All references herein to the time of day shall mean the time in New York, New York. Unless otherwise provided, all financial calculations shall be performed with Inventory valued on a first-in, first-out basis. Whenever the words “including” or “include” shall be used, such words shall be understood to mean “including, without limitation” or “include, without limitation”. A Default or an Event of Default shall be deemed to exist at all times during the period commencing on the date that such Default or Event of Default occurs to the date on which such Default or Event of Default is waived in writing pursuant to this Agreement or, in the case of a Default, is cured within any period of cure expressly provided for in this Agreement; and an Event of Default shall “continue” or be “continuing” until such Event of Default has been waived in writing by Required Lenders. Any Lien referred to in this Agreement or any of the Other Documents as having been created in favor of Agent, any agreement entered into by Agent pursuant to this Agreement or any of the Other Documents, any payment made by or to or funds received by Agent pursuant to or as contemplated by this Agreement or any of the Other Documents, or any act taken or omitted to be taken by Agent, shall, unless otherwise expressly provided, be created, entered into, made or received, or taken or omitted, for the benefit or account of Agent and Lenders. Wherever the phrase “to the best of Borrowers’ knowledge” or words of similar import relating to the knowledge or the awareness of any Borrower are used in this Agreement or Other Documents, such phrase shall mean and refer to (i) the actual knowledge of an Authorized Officer of any Borrower or (ii) the knowledge that an Authorized Officer would have obtained if he/she had engaged in good faith and diligent performance of his/her duties, including the making of such reasonably specific inquiries as may be necessary of the employees or agents of such Borrower and a good faith attempt to ascertain the existence or accuracy of the matter to which such phrase relates. All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or otherwise within the limitations of, another covenant shall not avoid the occurrence of a default if such action is taken or condition exists. In addition, all representations and warranties hereunder shall be given independent effect so that if a particular representation or warranty proves to be incorrect or is breached, the fact that another representation or warranty concerning the same or similar subject matter is correct or is not breached will not affect the incorrectness of a breach of a representation or warranty hereunder.

All of the property and assets of the Borrowers, including, without limitation, its Receivables, Equipment and Inventory, shall be valued in, and converted into, Dollars in accordance with PNC’s customary banking and conversion practices and procedures.

1.6. Permitted Encumbrances. The inclusion of Permitted Encumbrances in this Agreement is not intended to subordinate and shall not subordinate any Lien created by any of the security contemplated by this Agreement and the Other Documents to any Permitted Encumbrances.

(a) Amount of Revolving Advances. Subject to the terms and conditions set forth in this Agreement specifically including Section 2.1(a) below regarding Sand Tiger and Section 2.1(b), each Lender, severally and not jointly, will make Revolving Advances to Borrowers in aggregate amounts outstanding at any time equal to such Lender’s Commitment Percentage of the lesser of (x) the Maximum Revolving Advance Amount, less the outstanding amount of Swing Loans, less the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit or (y) an amount equal to the sum of:

(i) up to eighty-five percent (85%) (the “Receivables Advance Rate”) of Eligible Receivables, plus

(ii) up to the lesser of (A) up to eighty-five percent (85%), subject to the provisions of Section 2.1(b), of Eligible Unbilled Receivables or (B) $10,000,000 (“Unbilled Receivables Advance Rate”); plus

(iii) up to the lesser of (A) up to seventy-five percent (75%), subject to the provisions of Section 2.1(b) hereof (the “Sand Inventory Advance Rate”), of the value of Eligible Inventory, (B) up to eighty-five percent (85%), subject to the provisions of Section 2.1(b) hereof (the “NOLV Advance Rate”), of the net orderly liquidation value percentage (as evidenced by the most recent appraisal accepted by Agent in its Permitted Discretion, each, an “NOLV Appraisal”) of Eligible Inventory, or (C) $10,000,000 less amounts included in the calculation of the Formula Amount attributable to clause iv below; plus

(iv) the lowest of (A) the Sand Inventory Advance Rate of the value of Eligible In-Transit Inventory, (B) the NOLV Advance Rate of the net orderly liquidation value percentage (as evidenced by the most recent NOLV Appraisal) of Eligible In-Transit Inventory or (C) $10,000,000 less amounts included in the calculation of the Formula Amount attributable to clause iii above; plus

(v) up to the least of (A) up to eighty percent (80%) (the “Equipment Advance Rate”, and together with the Receivables Advance Rate, the Sand Inventory Advance Rate, the NOLV Advance Rate, the Equipment Advance Rate and the Unbilled Receivables Advance Rate, the “Advance Rates”) of the appraised net orderly liquidation value percentage of Eligible Equipment as set forth in the NOLV Appraisal most recently accepted by Agent, (B) the Eligible Equipment Sublimit or (C) up to eighty percent (80%) of the Maximum Revolving Advance Amount; minus

(vi) the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit, minus

(vii) such reserves as Agent may reasonably deem proper and necessary from time to time in the exercise of its Permitted Discretion, including in respect of Priority Payables relating to Sand Tiger.

The amount derived from the sum of (x) Sections 2.1(a)(y)(i), (ii), (iii), (iv) and (v) minus (y) Sections 2.1 (a)(y)(vi) and (vii) at any time and from time to time shall be referred to as the “Formula Amount”. Notwithstanding the foregoing, the parties agree that not more than $15,000,000 of the proceeds of direct Revolving Advances may be made available and remain outstanding on any day during the Term to Sand Tiger and which value of the Formula amount shall indirectly be advanced to, and constitute Indebtedness of, Sand Tiger (such Indebtedness, the “Sand Tiger Obligations”). The Revolving Advances shall be evidenced by one or more secured promissory notes (collectively, the “Revolving Credit Note”) substantially in the form attached hereto as Exhibit 2.1(a). Notwithstanding anything to the contrary contained in the foregoing or otherwise in this Agreement, the outstanding aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding shall not exceed an amount equal to the lesser of (i) the Maximum Revolving Advance Amount less the Maximum Undrawn Amount of all outstanding Letters of Credit or (ii) the Formula Amount.

(b) Discretionary Rights. The Advance Rates may be increased or decreased by Agent at any time and from time to time in the exercise of its Permitted Discretion. Each Borrower consents to any such increases or decreases and acknowledges that decreasing the Advance Rates or increasing or imposing reserves may limit or restrict Advances requested by Borrowing Agent. Prior to the occurrence and continuance of an Event of Default or Default, Agent shall give Borrowing Agent five (5) days prior written notice of its intention to decrease the Advance Rates. The rights of Agent under this subsection are subject to the provisions of Section 16.2(b).

2.2. Procedures for Requesting Revolving Advances; Procedures for Selection of Applicable Interest Rates for All Advances.

(a) Borrowing Agent on behalf of any Borrower may notify Agent prior to 1:00 p.m. on a Business Day of a Borrower’s request to incur, on that day, a Revolving Advance hereunder. Should any amount required to be paid as interest hereunder, or as fees or other charges under this Agreement or any other agreement with Agent or Lenders, or with respect to any other Obligation under this Agreement, become due, same shall be deemed a request for a Revolving Advance maintained as a Domestic Rate Loan as of the date such payment is due, in the amount required to pay in full such interest, fee, charge or Obligation, and such request shall be irrevocable.

(b) Notwithstanding the provisions of subsection (a) above, in the event any Borrower desires to obtain a LIBOR Rate Loan for any Advance (other than a Swing Loan), Borrowing Agent shall give Agent written notice by no later than 1:00 p.m. on the day which is three (3) Business Days prior to the date such LIBOR Rate Loan is to be borrowed, specifying (i) the date of the proposed borrowing (which shall be a Business Day), (ii) the type of borrowing and the amount of such Advance to be borrowed, which amount shall be in a minimum amount of $500,000 and in integral multiples of $100,000 thereafter, and (iii) the duration of the first Interest Period therefor. Interest Periods for LIBOR Rate Loans shall be for one (1), two (2), three (3) or six (6) months; provided that, if an Interest Period would end on a day that is not a Business Day, it shall end on the next succeeding Business Day unless such day falls in the next succeeding calendar month in which case the Interest Period shall end on the next preceding Business Day. No LIBOR Rate Loan shall be made available to any Borrower during the

continuance of a Default or an Event of Default. After giving effect to each requested LIBOR Rate Loan, including those which are converted from a Domestic Rate Loan under Section 2.2(e), there shall not be outstanding more than six (6) LIBOR Rate Loans, in the aggregate.

(c) Each Period of a LIBOR Rate Loan shall commence on the date such LIBOR Rate Loan is made and shall end on such date as Borrowing Agent may elect as set forth in subsection (b)(iii) above, provided that the exact length of each Interest Period shall be determined in accordance with the practice of the interbank market for offshore Dollar deposits and no Interest Period shall end after the last day of the Term.

(d) Borrowing Agent shall elect the initial Interest Period applicable to a LIBOR Rate Loan by its notice of borrowing given to Agent pursuant to Section 2.2(b) or by its notice of conversion given to Agent pursuant to Section 2.2(e), as the case may be. Borrowing Agent shall elect the duration of each succeeding Interest Period by giving irrevocable written notice to Agent of such duration not later than 1:00 p.m. on the day which is three (3) Business Days prior to the last day of the then current Interest Period applicable to such LIBOR Rate Loan. If Agent does not receive timely notice of the Interest Period elected by Borrowing Agent, Borrowing Agent shall be deemed to have elected to convert such LIBOR Rate Loan to a Domestic Rate Loan subject to Section 2.2(e) below.

(e) Provided that no Default or Event of Default shall have occurred and be continuing, Borrowing Agent may, on the last Business Day of the then current Interest Period applicable to any outstanding LIBOR Rate Loan, or on any Business Day with respect to Domestic Rate Loans, convert any such loan into a loan of another type in the same aggregate principal amount provided that any conversion of a LIBOR Rate Loan shall be made only on the last Business Day of the then current Interest Period applicable to such LIBOR Rate Loan. If Borrowing Agent desires to convert a loan, Borrowing Agent shall give Agent written notice by no later than 1:00 p.m. (i) on the day which is three (3) Business Days prior to the date on which such conversion is to occur with respect to a conversion from a Domestic Rate Loan to a LIBOR Rate Loan, or (ii) on the day which is one (1) Business Day prior to the date on which such conversion is to occur (which date shall be the last Business Day of the Interest Period for the applicable LIBOR Rate Loan) with respect to a conversion from a LIBOR Rate Loan to a Domestic Rate Loan, specifying, in each case, the date of such conversion, the loans to be converted and if the conversion is to a LIBOR Rate Loan, the duration of the first Interest Period therefor.

(f) At its option and upon written notice given prior to 1:00 p.m. at least three (3) Business Days prior to the date of such prepayment, any Borrower (other than Sand Tiger) may, subject to Section 2.2(g) hereof, prepay the LIBOR Rate Loans in whole at any time or in part from time to time with accrued interest on the principal being prepaid to the date of such repayment. Such Borrower shall specify the date of prepayment of Advances which are LIBOR Rate Loans and the amount of such prepayment. In the event that any prepayment of a LIBOR Rate Loan is required or permitted on a date other than the last Business Day of the then current Interest Period with respect thereto, such Borrower shall indemnify Agent and Lenders therefor in accordance with Section 2.2(g) hereof.

(g) Each Borrower (other than Sand Tiger) shall indemnify Agent and Lenders and hold Agent and Lenders harmless from and against any and all losses or expenses that Agent and Lenders may sustain or incur as a consequence of any prepayment, conversion of or any default by any Borrower (other than Sand Tiger) in the payment of the principal of or interest on any LIBOR Rate Loan or failure by any such Borrower to complete a borrowing of, a prepayment of or conversion of or to a LIBOR Rate Loan after notice thereof has been given, including, but not limited to, any interest payable by Agent or Lenders to lenders of funds obtained by it in order to make or maintain its LIBOR Rate Loans hereunder. A certificate as to any additional amounts payable pursuant to the foregoing sentence submitted by Agent or any Lender to Borrowing Agent shall be conclusive absent manifest error.

(h) Notwithstanding any other provision hereof, if any Applicable Law, treaty, regulation or directive, or any change therein or in the interpretation or application thereof, including without limitation any Change in Law, shall make it unlawful for Lenders or any Lender (for purposes of this subsection (h), the term “Lender” shall include any Lender and the office or branch where any Lender or any Person controlling such Lender makes or maintains any LIBOR Rate Loans) to make or maintain its LIBOR Rate Loans, the obligation of Lenders (or such affected Lender) to make LIBOR Rate Loans hereunder shall forthwith be cancelled and Borrowers shall, if any affected LIBOR Rate Loans are then outstanding, promptly upon request from Agent, either pay all such affected LIBOR Rate Loans or convert such affected LIBOR Rate Loans into loans of another type. If any such payment or conversion of any LIBOR Rate Loan is made on a day that is not the last day of the Interest Period applicable to such LIBOR Rate Loan, Borrowers shall pay Agent, upon Agent’s request, such amount or amounts set forth in clause (g) above. A certificate as to any additional amounts payable pursuant to the foregoing sentence submitted by Lenders to Borrowing Agent shall be conclusive absent manifest error.

(a) Subject to the terms and conditions set forth in this Agreement, and in order to minimize the transfer of funds between Lenders and Agent for administrative convenience, Agent, Lenders holding Commitments and Swing Loan Lender agree that in order to facilitate the administration of this Agreement, Swing Loan Lender may, at its election and option made in its sole discretion cancelable at any time for any reason whatsoever, make swing loan advances (“Swing Loans”) available to Borrowers as provided for in this Section 2.4 at any time or from time to time after the date hereof to, but not including, the expiration of the Term, in an aggregate principal amount up to but not in excess of the Maximum Swing Loan Advance Amount, provided that the outstanding aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding shall not exceed an amount equal to the lesser of (i) the Maximum Revolving Advance Amount less the Maximum Undrawn Amount of all outstanding Letters of Credit or (ii) the Formula Amount and shall be subject to the sublimits in Section 2.1(a). All Swing Loans shall be Domestic Rate Loans only. Borrowers may borrow (at the option and election of Swing Loan Lender), repay and reborrow (at the option and election of Swing Loan Lender) Swing Loans and Swing Loan Lender may make Swing Loans as provided in this Section 2.4 during the period between Settlement Dates. All Swing Loans shall be evidenced by a secured promissory note (the “Swing Loan Note”) substantially in the form

attached hereto as Exhibit 2.4(a). Swing Loan Lender’s agreement to make Swing Loans under this Agreement is cancelable at any time for any reason whatsoever and the making of Swing Loans by Swing Loan Lender from time to time shall not create any duty or obligation, or establish any course of conduct, pursuant to which Swing Loan Lender shall thereafter be obligated to make Swing Loans in the future

(b) Upon either (i) any request by Borrowing Agent for a Revolving Advance made pursuant to Section 2.2(a) hereof or (ii) the occurrence of any deemed request by Borrowers for a Revolving Advance pursuant to the provisions of the last sentence of Section 2.2(a) hereof, Swing Loan Lender may elect, in its sole discretion, to have such request or deemed request treated as a request for a Swing Loan, and may advance same day funds to Borrowers as a Swing Loan; provided that notwithstanding anything to the contrary provided for herein, Swing Loan Lender may not make Swing Loan Advances if Swing Loan Lender has been notified by Agent or by Required Lenders that one or more of the applicable conditions set forth in Section 8.2 of this Agreement have not been satisfied or the Commitments have been terminated for any reason.

(c) Upon the making of a Swing Loan (whether before or after the occurrence of a Default or an Event of Default and regardless of whether a Settlement has been requested with respect to such Swing Loan), each Lender holding a Commitment shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from Swing Loan Lender, without recourse or warranty, an undivided interest and participation in such Swing Loan in proportion to its Commitment Percentage. Swing Loan Lender or Agent may, at any time, require the Lenders holding Commitments to fund such participations by means of a Settlement as provided for in Section 2.6(d) below. From and after the date, if any, on which any Lender holding a Commitment is required to fund, and funds, its participation in any Swing Loans purchased hereunder, Agent shall promptly distribute to such Lender its Commitment Percentage of all payments of principal and interest and all proceeds of Collateral received by Agent in respect of such Swing Loan; provided that no Lender holding a Commitment shall be obligated in any event to make Revolving Advances in an amount in excess of its Commitment Amount minus its Participation Commitment (taking into account any reallocations under Section 2.22) of the Maximum Undrawn Amount of all outstanding Letters of Credit.

2.5. Disbursement of Advance Proceeds. All Advances shall be disbursed from whichever office or other place Agent may designate from time to time and, together with any and all other Obligations of Borrowers to Agent or Lenders, shall be charged to Borrowers’ Account or Sand Tiger’s Account, as applicable, on Agent’s books. The proceeds of each Revolving Advance or Swing Loan requested by Borrowing Agent on behalf of any Borrower or deemed to have been requested by any Borrower under Sections 2.2(a), 2.6(b) or 2.14 hereof shall, (i) with respect to requested Revolving Advances, to the extent Lenders make such Revolving Advances in accordance with Section 2.2(a), 2.6(b) or 2.14 hereof, and with respect to Swing Loans made upon any request by Borrowing Agent for a Revolving Advance to the extent Swing Loan Lender makes such Swing Loan in accordance with Section 2.4(b) hereof, be made available to the applicable Borrower on the day so requested by way of credit to such Borrower’s operating account at PNC, or such other bank as Borrowing Agent may designate following

notification to Agent, in immediately available federal funds or other immediately available funds or, (ii) with respect to Revolving Advances deemed to have been requested by any Borrower or Swing Loans made upon any deemed request for a Revolving Advance by any Borrower, be disbursed to Agent to be applied to the outstanding Obligations giving rise to such deemed request. During the Term, Borrowers may use the Revolving Advances and Swing Loans by borrowing, prepaying and reborrowing, all in accordance with the terms and conditions hereof.

(a) Each borrowing of Revolving Advances shall be advanced according to the applicable Commitment Percentages of Lenders holding the Commitments (subject to any contrary terms of Section 2.22). Each borrowing of Swing Loans shall be advanced by Swing Loan Lender alone.

(b) Promptly after receipt by Agent of a request or a deemed request for a Revolving Advance pursuant to Section 2.2(a) and, with respect to Revolving Advances, to the extent Agent elects not to provide a Swing Loan or the making of a Swing Loan would result in the aggregate amount of all outstanding Swing Loans exceeding the maximum amount permitted in Section 2.4(a), Agent shall notify Lenders holding the Commitments of its receipt of such request specifying the information provided by Borrowing Agent and the apportionment among Lenders of the requested Revolving Advance as determined by Agent in accordance with the terms hereof. Each Lender shall remit the principal amount of each Revolving Advance to Agent such that Agent is able to, and Agent shall, to the extent the applicable Lenders have made funds available to it for such purpose and subject to Section 8.2, fund such Revolving Advance to Borrowers in U.S. Dollars and immediately available funds at the Payment Office prior to the close of business, on the applicable borrowing date; provided that if any applicable Lender fails to remit such funds to Agent in a timely manner, Agent may elect in its sole discretion to fund with its own funds the Revolving Advance of such Lender on such borrowing date, and such Lender shall be subject to the repayment obligation in Section 2.6(c) hereof.

(c) Unless Agent shall have been notified by telephone, confirmed in writing, by any Lender holding a Commitment that such Lender will not make the amount which would constitute its applicable Commitment Percentage of the requested Revolving Advance available to Agent, Agent may (but shall not be obligated to) assume that such Lender has made such amount available to Agent on such date in accordance with Section 2.6(b) and may, in reliance upon such assumption, make available to Borrowers a corresponding amount. Agent will promptly notify Borrowing Agent of its receipt of any such notice from a Lender. In such event, if a Lender has not in fact made its applicable Commitment Percentage of the requested Revolving Advance available to Agent, then the applicable Lender and Borrowers severally agree to pay to Agent on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to Borrowers through but excluding the date of payment to Agent, at (i) in the case of a payment to be made by such Lender, the greater of (A) (x) the daily average Federal Funds Effective Rate (computed on the basis of a year of 360 days) during such period as quoted by Agent, times (y) such amount or (B) a rate determined by Agent in accordance with banking industry rules on interbank compensation, and (ii) in the case of a payment to be made by Borrowers, the Revolving Interest Rate for Revolving

Advances that are Domestic Rate Loans. If such Lender pays its share of the applicable Revolving Advance to Agent, then the amount so paid shall constitute such Lender’s Revolving Advance. Any payment by Borrowers shall be without prejudice to any claim Borrowers may have against a Lender holding a Commitment that shall have failed to make such payment to Agent. A certificate of Agent submitted to any Lender or Borrowers with respect to any amounts owing under this paragraph (c) shall be conclusive, in the absence of manifest error.

(d) Agent, on behalf of Swing Loan Lender, shall demand settlement (a “Settlement”) of all or any Swing Loans with Lenders holding the Commitments on at least a weekly basis, or on any more frequent date that Agent elects or that Swing Loan Lender at its option exercisable for any reason whatsoever may request, by notifying Lenders holding the Commitments of such requested Settlement by facsimile, telephonic or electronic transmission no later than 3:00 p.m. on the date of such requested Settlement (the “Settlement Date”). Subject to any contrary provisions of Section 2.22, each Lender holding a Commitment shall transfer the amount of such Lender’s Commitment Percentage of the outstanding principal amount (plus interest accrued thereon to the extent requested by Agent) of the applicable Swing Loan with respect to which Settlement is requested by Agent, to such account of Agent as Agent may designate not later than 5:00 p.m. on such Settlement Date if requested by Agent by 3:00 p.m., otherwise not later than 5:00 p.m. on the next Business Day. Settlements may occur at any time notwithstanding that the conditions precedent to making Revolving Advances set forth in Section 8.2 have not been satisfied or the Commitments shall have otherwise been terminated at such time. All amounts so transferred to Agent shall be applied against the amount of outstanding Swing Loans and, when so applied shall constitute Revolving Advances of such Lenders accruing interest as Domestic Rate Loans. If any such amount is not transferred to Agent by any Lender holding a Commitment on such Settlement Date, Agent shall be entitled to recover such amount on demand from such Lender together with interest thereon as specified in Section 2.6(c).

(e) If any Lender or Participant (a “Benefited Lender”) shall at any time receive any payment of all or part of its Advances, or interest thereon, or receive any Collateral in respect thereof (whether voluntarily or involuntarily or by set-off) in a greater proportion than any such payment to and Collateral received by any other Lender, if any, in respect of such other Lender’s Advances, or interest thereon, and such greater proportionate payment or receipt of Collateral is not expressly permitted hereunder, such Benefited Lender shall purchase for cash from the other Lenders a participation in such portion of each such other Lender’s Advances, or shall provide such other Lender with the benefits of any such Collateral, or the proceeds thereof, as shall be necessary to cause such Benefited Lender to share the excess payment or benefits of such Collateral or proceeds ratably with each of the other Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under Applicable Law, that each Lender so purchasing a portion of another Lender’s Advances may exercise all rights of payment (including rights of set-off) with respect to such portion as fully as if such Lender were the direct holder of such portion, and the obligations owing to each such purchasing Lender in respect of such participation and such purchased portion of any other Lender’s Advances shall be part of the

Obligations secured by the Collateral, and the obligations owing to each such purchasing Lender in respect of such participation and such purchased portion of any other Lender’s Advances shall be part of the Obligations secured by the Collateral.

2.7. Maximum Advances. The aggregate balance of Revolving Advances plus Swing Loans outstanding at any time shall not exceed the lesser of (a) the Maximum Revolving Advance Amount less the aggregate Maximum Undrawn Amount of all issued and outstanding Letters of Credit or (b) the Formula Amount.

(a) The Revolving Advances and Swing Loans shall be due and payable in full on the last day of the Term subject to earlier prepayment as herein provided. Notwithstanding the foregoing, all Advances shall be subject to earlier repayment upon (x) acceleration upon the occurrence and continuance of an Event of Default under this Agreement or (y) termination of this Agreement by the Borrowing Agent. Each payment (including each prepayment) by any Borrower (other than Sand Tiger) on account of the principal of and interest on the Advances shall be applied, first to the outstanding Swing Loans and next, pro rata according to the applicable Commitment Percentages of Lenders, to the outstanding Advances (subject to any contrary provisions of Section 2.22). Each payment (including each prepayment) by Sand Tiger on account of the principal of and interest on the Advances in respect of Sand Tiger shall be applied, first to the outstanding Swing Loans made in respect of Sand Tiger and next, pro rata according to the applicable Commitment Percentages of Lenders, to the outstanding Advances made in respect of Sand Tiger (subject to any contrary provisions of Section 2.22).

(b) Each Borrower recognizes that the amounts evidenced by checks, notes, drafts or any other items of payment relating to and/or proceeds of Collateral may not be collectible by Agent on the date received by Agent. Agent shall conditionally credit Borrowers’ Account for each item of payment on the next Business Day after the Business Day on which such item of payment is received by Agent (and the Business Day on which each such item of payment is so credited shall be referred to, with respect to such item, as the “Application Date”). Agent is not, however, required to credit the applicable Borrowers’ Account for the amount of any item of payment which is unsatisfactory to Agent and Agent may charge Borrowers’ Account for the amount of any item of payment which is returned, for any reason whatsoever, to Agent unpaid. Subject to the foregoing, Borrowers agree that for purposes of computing the interest charges under this Agreement, each item of payment received by Agent shall be deemed applied by Agent on account of the Obligations on its respective Application Date. All proceeds received by Agent during a Trigger Period shall be applied to the Obligations in accordance with Section 4.8(h).

(c) All payments of principal, interest and other amounts payable hereunder, or under any of the Other Documents shall be made to Agent at the Payment Office not later than 1:00 p.m. on the due date therefor in Dollars in federal funds or other funds immediately available to Agent. Agent shall have the right to effectuate payment of any and all Obligations due and owing hereunder by charging the applicable Borrowers’ Account or by making Advances as provided in Section 2.2 hereof.

(d) Except as expressly provided herein, all payments (including prepayments) to be made by any Borrower on account of principal, interest, fees and other amounts payable hereunder shall be made without deduction, setoff or counterclaim and shall be made to Agent on behalf of Lenders to the Payment Office, in each case on or prior to 1:00 p.m., in Dollars and in immediately available funds.

2.9. Repayment of Excess Advances. If at any time the aggregate balance of outstanding Revolving Advances, Swing Loans, and/or Advances taken as a whole exceeds the maximum amount of such type of Advances and/or Advances taken as a whole (as applicable) permitted hereunder, such excess Advances shall be immediately due and payable without the necessity of any demand, at the Payment Office, whether or not a Default or an Event of Default has occurred.

2.10. Statement of Account. Agent shall maintain, in accordance with its customary procedures, loan accounts (“Borrowers’ Accounts”), one in the names of Borrowers other than Sand Tiger and one in the name of Sand Tiger for loans made to it, in which shall be recorded the date and amount of each Advance made by Agent or Lenders and the date and amount of each payment in respect thereof; provided, however, the failure by Agent to record the date and amount of any Advance shall not adversely affect Agent or any Lender. Each month, Agent shall send to Borrowing Agent a statement showing the accounting for the Advances made, payments made or credited in respect thereof, and other transactions between Agent, Lenders and Borrowers during such month. The monthly statements shall be deemed correct and binding upon Borrowers in the absence of manifest error and shall constitute an account stated between Lenders and Borrowers unless Agent receives a written statement of Borrowers’ specific exceptions thereto within thirty (30) days after such statement is received by Borrowing Agent. The records of Agent with respect to the Borrowers’ Accounts shall be conclusive evidence absent manifest error of the amounts of Advances and other charges thereto and of payments applicable thereto.

(a) Subject to the terms and conditions hereof, Issuer shall issue or cause the issuance of standby and/or trade letters of credit denominated in Dollars (“Letters of Credit”) for the account of any Borrower except to the extent that the issuance thereof would then cause the sum of (i) the outstanding Revolving Advances plus (ii) the outstanding Swing Loans, plus (iii) the Maximum Undrawn Amount of all outstanding Letters of Credit, plus (iv) the Maximum Undrawn Amount of the Letter of Credit to be issued to exceed the lesser of (x) the Maximum Revolving Advance Amount or (y) the Formula Amount (calculated without giving effect to the deductions provided for in Section 2.1(a)(y)(vi)). The Maximum Undrawn Amount of all outstanding Letters of Credit shall not exceed in the aggregate at any time the Letter of Credit Sublimit. All disbursements or payments related to Letters of Credit shall be deemed to be Domestic Rate Loans consisting of Revolving Advances and shall bear interest at the Revolving Interest Rate for Domestic Rate Loans. Letters of Credit that have not been drawn upon shall not bear interest (but fees shall accrue in respect of outstanding Letters of Credit as provided in Section 3.2 hereof).

(b) Notwithstanding any provision of this Agreement, Issuer shall not be under any obligation to issue any Letter of Credit if (i) any order, judgment or decree of any Governmental Body or arbitrator shall by its terms purport to enjoin or restrain Issuer from issuing any Letter of Credit, or any Law applicable to Issuer or any request or directive (whether or not having the force of law) from any Governmental Body with jurisdiction over Issuer shall prohibit, or request that Issuer refrain from, the issuance of letters of credit generally or the Letter of Credit in particular or shall impose upon Issuer with respect to the Letter of Credit any restriction, reserve or capital requirement (for which Issuer is not otherwise compensated hereunder) not in effect on the date of this Agreement, or shall impose upon Issuer any unreimbursed loss, cost or expense which was not applicable on the date of this Agreement, and which Issuer in good faith deems material to it, or (ii) the issuance of the Letter of Credit would violate one or more policies of Issuer applicable to letters of credit generally.

(a) Borrowing Agent, on behalf of any Borrower, may request Issuer to issue or cause the issuance of a Letter of Credit by delivering to Issuer, with a copy to Agent at the Payment Office, prior to 1:00 p.m., at least five (5) Business Days prior to the proposed date of issuance, such Issuer’s form of Letter of Credit Application (the “Letter of Credit Application”) completed to the satisfaction of Agent and Issuer; and, such other certificates, documents and other papers and information as Agent or Issuer may reasonably request. Issuer shall not issue any requested Letter of Credit if such Issuer has received notice from Agent or any Lender that one or more of the applicable conditions set forth in Section 8.2 of this Agreement have not been satisfied or the commitments of Lenders to make Revolving Advances hereunder have been terminated for any reason.

(b) Each Letter of Credit shall, among other things, (i) provide for the payment of sight drafts, other written demands for payment, or acceptances of usance drafts when presented for honor thereunder in accordance with the terms thereof and when accompanied by the documents described therein and (ii) have an expiry date not later than twelve (12) months after such Letter of Credit’s date of issuance and any automatic renewals thereof and in no event later than the last day of the Term. Each standby Letter of Credit shall be subject either to the Uniform Customs and Practice for Documentary Credits as most recently published by the International Chamber of Commerce at the time a Letter of Credit is issued (the “UCP”) or the International Standby Practices (ISP98-International Chamber of Commerce Publication Number 590) (the “ISP98 Rules”), or any subsequent revision thereof at the time a standby Letter of Credit is issued, as determined by Issuer, and each trade Letter of Credit shall be subject to the UCP. In addition, no trade Letter of Credit may permit the presentation of an ocean bill of lading that includes a condition that the original bill of lading is not required to claim the goods shipped thereunder.

(c) Agent shall use its reasonable efforts to notify Lenders of the request by Borrowing Agent for a Letter of Credit hereunder.

(a) Borrowing Agent shall authorize and direct any Issuer to name the applicable Borrower as the “Applicant” or “Account Party” of each Letter of Credit. If Agent is not the Issuer of any Letter of Credit, Borrowing Agent shall authorize and direct the Issuer to deliver to Agent all instruments, documents, and other writings and property received by the Issuer pursuant to the Letter of Credit and to accept and rely upon Agent’s instructions and agreements with respect to all matters arising in connection with the Letter of Credit or the application therefor.

(b) In connection with all trade Letters of Credit issued or caused to be issued by Issuer under this Agreement, each Borrower hereby appoints Issuer, or its designee, as its attorney, with full power and authority if an Event of Default shall have occurred and continues: (i) to sign and/or endorse such Borrower’s name upon any warehouse or other receipts, and acceptances; (ii) to sign such Borrower’s name on bills of lading; (iii) to clear Inventory through the United States of America Customs Department or Canada Border Services Agency, as applicable, (“Customs”) in the name of such Borrower or Issuer or Issuer’s designee, and to sign and deliver to Customs officials powers of attorney in the name of such Borrower for such purpose; and (iv) to complete in such Borrower’s name or Issuer’s, or in the name of Issuer’s designee, any order, sale or transaction, obtain the necessary documents in connection therewith, and collect the proceeds thereof. Neither Agent, Issuer nor their attorneys will be liable for any acts or omissions nor for any error of judgment or mistakes of fact or law, except for Agent’s, Issuer’s or their respective attorney’s gross negligence or willful misconduct. This power, being coupled with an interest, is irrevocable as long as any Letters of Credit remain outstanding.

(a) Immediately upon the issuance of each Letter of Credit, each Lender holding a Commitment shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from Issuer a participation in each Letter of Credit and each drawing thereunder in an amount equal to such Lender’s Commitment Percentage of the Maximum Undrawn Amount of such Letter of Credit (as in effect from time to time) and the amount of such drawing, respectively.

(b) In the event of any request for a drawing under a Letter of Credit by the beneficiary or transferee thereof, Issuer will promptly notify Agent and Borrowing Agent. Regardless of whether Borrowing Agent shall have received such notice, Borrowers shall reimburse (such obligation to reimburse Issuer shall sometimes be referred to as a “Reimbursement Obligation”) Issuer prior to 12:00 Noon, on each date that an amount is paid by Issuer under any Letter of Credit (each such date, a “Drawing Date”) in an amount equal to the amount so paid by Issuer. In the event Borrowers fail to reimburse Issuer for the full amount of any drawing under any Letter of Credit by 12:00 Noon, on the Drawing Date, Issuer will promptly notify Agent and each Lender holding a Commitment thereof, and Borrowers shall be automatically deemed to have requested that a Revolving Advance maintained as a Domestic Rate Loan be made by Lenders to be disbursed on the Drawing Date under such Letter of Credit, and Lenders holding the Commitments shall be unconditionally obligated to fund such Revolving Advance (all whether or not the conditions specified in Section 8.2 are then satisfied

or the commitments of Lenders to make Revolving Advances hereunder have been terminated for any reason) as provided for in Section 2.14(c) immediately below. Any notice given by Issuer pursuant to this Section 2.14(b) may be oral if promptly confirmed in writing; provided that the lack of such a confirmation shall not affect the conclusiveness or binding effect of such notice.

(c) Each Lender holding a Commitment shall upon any notice pursuant to Section 2.14(b) make available to Issuer through Agent at the Payment Office an amount in immediately available funds equal to its Commitment Percentage (subject to any contrary provisions of Section 2.22) of the amount of the drawing, whereupon the participating Lenders shall (subject to Section 2.14(d)) each be deemed to have made a Revolving Advance maintained as a Domestic Rate Loan to Borrowers in that amount. If any Lender holding a Commitment so notified fails to make available to Agent, for the benefit of Issuer, the amount of such Lender’s Commitment Percentage of such amount by 2:00 p.m. on the Drawing Date, then interest shall accrue on such Lender’s obligation to make such payment, from the Drawing Date to the date on which such Lender makes such payment (i) at a rate per annum equal to the Federal Funds Effective Rate during the first three (3) days following the Drawing Date and (ii) at a rate per annum equal to the rate applicable to Revolving Advances maintained as a Domestic Rate Loan on and after the fourth day following the Drawing Date. Agent and Issuer will promptly give notice of the occurrence of the Drawing Date, but failure of Agent or Issuer to give any such notice on the Drawing Date or in sufficient time to enable any Lender holding a Commitment to effect such payment on such date shall not relieve such Lender from its obligations under this Section 2.14(c), provided that such Lender shall not be obligated to pay interest as provided in Section 2.14(c)(i) and (ii) until and commencing from the date of receipt of notice from Agent or Issuer of a drawing.

(d) With respect to any unreimbursed drawing that is not converted into a Revolving Advance maintained as a Domestic Rate Loan to Borrowers in whole or in part as contemplated by Section 2.14(b), because of Borrowers’ failure to satisfy the conditions set forth in Section 8.2 hereof (other than any notice requirements) or for any other reason, Borrowers shall be deemed to have incurred from Agent, subject to Section 16.19, a borrowing (each a “Letter of Credit Borrowing”) in the amount of such drawing. Such Letter of Credit Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the rate per annum applicable to a Revolving Advance maintained as a Domestic Rate Loan. Each applicable Lender’s payment to Agent pursuant to Section 2.14(c) shall be deemed to be a payment in respect of its participation in such Letter of Credit Borrowing and shall constitute a “Participation Advance” from such Lender in satisfaction of its Participation Commitment in respect of the applicable Letter of Credit under this Section 2.14.

(e) Each applicable Lender’s Participation Commitment in respect of the Letters of Credit shall continue until the last to occur of any of the following events: (x) Issuer ceases to be obligated to issue or cause to be issued Letters of Credit hereunder; (y) no Letter of Credit issued or created hereunder remains outstanding and uncancelled; and (z) all Persons (other than Borrowers) have been fully reimbursed for all payments made under or relating to Letters of Credit.

(a) Upon (and only upon) receipt by Agent for the account of Issuer of immediately available funds from Borrowers (i) in reimbursement of any payment made by Issuer or Agent under the Letter of Credit with respect to which any Lender has made a Participation Advance to Agent, or (ii) in payment of interest on such a payment made by Issuer or Agent under such a Letter of Credit, Agent will pay to each Lender holding a Commitment, in the same funds as those received by Agent, the amount of such Lender’s Commitment Percentage of such funds, except Agent shall retain the amount of the Commitment Percentage of such funds of any Lender holding a Commitment that did not make a Participation Advance in respect of such payment by Agent (and, to the extent that any of the other Lender(s) holding the Commitment have funded any portion such Defaulting Lender’s Participation Advance in accordance with the provisions of Section 2.22, Agent will pay over to such Non-Defaulting Lenders a pro rata portion of the funds so withheld from such Defaulting Lender).

(b) If Issuer or Agent is required at any time to return to any Borrower, or to a trustee, receiver, liquidator, monitor, custodian, or any official in any insolvency proceeding, any portion of the payments made by Borrowers to Issuer or Agent pursuant to Section 2.15(a) in reimbursement of a payment made under the Letter of Credit or interest or fee thereon, each applicable Lender shall, on demand of Agent, forthwith return to Issuer or Agent the amount of its Commitment Percentage of any amounts so returned by Issuer or Agent plus interest at the Federal Funds Effective Rate.

2.16. Documentation. Each Borrower agrees to be bound by the terms of the Letter of Credit Application and by Issuer’s interpretations of any Letter of Credit issued on behalf of such Borrower and by Issuer’s written regulations and customary practices relating to letters of credit, though Issuer’s interpretations may be different from such Borrower’s own. In the event of a conflict between the Letter of Credit Application and this Agreement, this Agreement shall govern. It is understood and agreed that, except in the case of gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment), Issuer shall not be liable for any error, negligence and/or mistakes, whether of omission or commission, in following Borrowing Agent’s or any Borrower’s instructions or those contained in the Letters of Credit or any modifications, amendments or supplements thereto.

2.17. Determination to Honor Drawing Request. In determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, Issuer shall be responsible only to determine that the documents and certificates required to be delivered under such Letter of Credit have been delivered and that they comply on their face with the requirements of such Letter of Credit and that any other drawing condition appearing on the face of such Letter of Credit has been satisfied in the manner so set forth.

2.18. Nature of Participation and Reimbursement Obligations. The obligation of each Lender holding a Commitment in accordance with this Agreement to make the Revolving Advances or Participation Advances as a result of a drawing under a Letter of Credit, and the obligations of Borrowers to reimburse Issuer upon a draw under a Letter of Credit, shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Section 2.18 under all circumstances, including the following circumstances:

(i) any set-off, counterclaim, recoupment, defense or other right which such Lender or any Borrower, as the case may be, may have against Issuer, Agent, any Borrower or Lender, as the case may be, or any other Person for any reason whatsoever;

(ii) the failure of any Borrower or any other Person to comply, in connection with a Letter of Credit Borrowing, with the conditions set forth in this Agreement for the making of a Revolving Advance, it being acknowledged that such conditions are not required for the making of a Letter of Credit Borrowing and the obligation of Lenders to make Participation Advances under Section 2.14;

(iv) any claim of breach of warranty that might be made by any Borrower, Agent, Issuer or any Lender against the beneficiary of a Letter of Credit, or the existence of any claim, set-off, recoupment, counterclaim, cross-claim, defense or other right which any Borrower, Agent, Issuer or any Lender may have at any time against a beneficiary, any successor beneficiary or any transferee of any Letter of Credit or assignee of the proceeds thereof (or any Persons for whom any such transferee or assignee may be acting), Issuer, Agent or any Lender or any other Person, whether in connection with this Agreement, the transactions contemplated herein or any unrelated transaction (including any underlying transaction between any Borrower or any Subsidiaries of such Borrower and the beneficiary for which any Letter of Credit was procured);

(v) the lack of power or authority of any signer of (or any defect in or forgery of any signature or endorsement on) or the form of or lack of validity, accuracy, enforceability or genuineness of any draft, demand, instrument, certificate or other document presented under or in connection with any Letter of Credit, or any fraud or alleged fraud in connection with any Letter of Credit, or the transport of any property or provision of services relating to a Letter of Credit, in each case even if Issuer or any of Issuer’s Affiliates has been notified thereof;

(vi) payment by Issuer under any Letter of Credit against presentation of a demand, draft or certificate or other document which is forged or does not fully comply with the terms of such Letter of Credit (provided that the foregoing shall not excuse Issuer from any obligation under the terms of any applicable Letter of Credit to require the presentation of documents that on their face appear to satisfy any applicable requirements for drawing under such Letter of Credit prior to honoring or paying any such draw);

(vii) the solvency of, or any acts or omissions by, any beneficiary of any Letter of Credit, or any other Person having a role in any transaction or obligation relating to a Letter of Credit, or the existence, nature, quality, quantity, condition, value or other characteristic of any property or services relating to a Letter of Credit;

(viii) any failure by Issuer or any of Issuer’s Affiliates to issue any Letter of Credit in the form requested by Borrowing Agent, unless Agent and Issuer have each received written notice from Borrowing Agent of such failure within three (3) Business Days after Issuer shall have furnished Agent and Borrowing Agent a copy of such Letter of Credit and such error is material and no drawing has been made thereon prior to receipt of such notice;

(xi) the occurrence or continuance of an insolvency proceeding with respect to any Borrower or any Guarantor;

(xii) the fact that a Default or an Event of Default shall have occurred and be continuing; and

(xiii) the fact that the Term shall have expired or this Agreement or the obligations of Lenders to make Advances have been terminated.

(a) As between Borrowers and Issuer, Swing Loan Lender, Agent and Lenders, each Borrower assumes all risks of the acts and omissions of, or misuse of the Letters of Credit by, the respective beneficiaries of such Letters of Credit, other than the gross negligence or willful misconduct of the Agent as determined by a final and non-appealable judgment of a court of competent jurisdiction. In furtherance and not in limitation of the foregoing, Issuer shall not be responsible for: (i) the form, validity, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an issuance of any such Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if Issuer or any of its Affiliates shall have been notified thereof); (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any such Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) the failure of the beneficiary of any such Letter of Credit, or any other party to which such Letter of Credit may be transferred, to comply fully with any conditions required in order to draw upon such Letter of Credit or any other claim of any Borrower against any beneficiary of such Letter of Credit, or any such transferee, or any dispute between or among any Borrower and any beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, facsimile, telex or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing under such Letter of Credit; or (viii) any consequences arising from causes beyond the control of Issuer, including any Governmental Acts, and none of the above shall affect or impair, or prevent the vesting of, any of Issuer’s rights or powers hereunder. Nothing in the preceding sentence

shall relieve Issuer from liability for Issuer’s gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment) in connection with actions or omissions described in such clauses (i) through (viii) of such sentence. In no event shall Issuer or Issuer’s Affiliates be liable to any Borrower for any indirect, consequential, incidental, punitive, exemplary or special damages or expenses (including without limitation attorneys’ fees), or for any damages resulting from any change in the value of any property relating to a Letter of Credit.

(b) Without limiting the generality of the foregoing, Issuer and each of its Affiliates: (i) may rely on any oral or other communication believed in good faith by Issuer or such Affiliate to have been authorized or given by or on behalf of the applicant for a Letter of Credit; (ii) may honor any presentation if the documents presented appear on their face substantially to comply with the terms and conditions of the relevant Letter of Credit; (iii) may honor a previously dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court order, to settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to the same extent as if such presentation had initially been honored, together with any interest paid by Issuer or its Affiliates; (iv) may honor any drawing that is payable upon presentation of a statement advising negotiation or payment, upon receipt of such statement (even if such statement indicates that a draft or other document is being delivered separately), and shall not be liable for any failure of any such draft or other document to arrive, or to conform in any way with the relevant Letter of Credit; (v) may pay any paying or negotiating bank claiming that it rightfully honored under the laws or practices of the place where such bank is located; and (vi) may settle or adjust any claim or demand made on Issuer or its Affiliate in any way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee or of indemnity issued to a steamship agent or carrier or any document or instrument of like import (each an “Order”) and honor any drawing in connection with any Letter of Credit that is the subject of such Order, notwithstanding that any drafts or other documents presented in connection with such Letter of Credit fail to conform in any way with such Letter of Credit.

(c) In furtherance and extension and not in limitation of the specific provisions set forth above, any action taken or omitted by Issuer under or in connection with the Letters of Credit issued by it or any documents and certificates delivered thereunder, if taken or omitted in good faith and without gross negligence (as determined by a court of competent jurisdiction in a final non-appealable judgment), shall not put Issuer under any resulting liability to any Borrower, Agent or any Lender.

(a) Subject to Section 7.1 hereof, when any Borrower sells or otherwise disposes of any Collateral other than Inventory in the ordinary course of business or as otherwise permitted under this Agreement, each applicable Borrower shall repay the Advances made for its benefit and/or made directly or indirectly to it in an amount equal to the net proceeds of such sale (i.e., gross proceeds less the reasonable direct costs of such sales or other dispositions) if such net proceeds are in excess of $1,000,000, such repayments to be made promptly but in no event more than one (1) Business Day following receipt of such net proceeds, and until the date of payment, such proceeds shall be and shall be deemed to be held in trust exclusively for Agent.

The foregoing shall not be deemed to be implied consent to any such sale otherwise prohibited by the terms and conditions hereof. Such repayments shall be applied to the remaining Advances made for its benefit and/or made directly or indirectly to it (including cash collateralization of all Obligations relating to any outstanding Letters of Credit (issued in the case of Sand Tiger on its behalf only) in accordance with the provisions of Section 3.2(b); provided however that if no Default or Event of Default has occurred and is continuing, such repayments shall be applied to cash collateralize any Obligations related to outstanding Letters of Credit last) in such order as Agent may determine, subject to Borrowers’ ability to reborrow Revolving Advances in accordance with the terms hereof or (ii) if the Collateral disposed of is equipment other than as set forth in (i) above or other Collateral, to the remaining Advances made for its benefit and/or made directly or indirectly to it (including cash collateralization of all Obligations relating to any outstanding Letters of Credit in accordance with the provisions of Section 3.2(b), provided however that if no Default or Event of Default has occurred and is continuing, such repayments shall be applied to cash collateralize any Obligations related to outstanding Letters of Credit last) in such order as Agent may determine, subject to Borrowers’ ability to reborrow Revolving Advances in accordance with the terms hereof. Any such repayment shall not reduce the Maximum Revolving Advance Amount.

(b) Upon the consummation of any Qualified IPO, each applicable Borrower shall repay the Advances made for its benefit and/or made directly or indirectly to it in an amount necessary to cause Borrowers’ Excess Availability to at least equal to $75,000,000 after giving effect to such repayment, such repayments to be made promptly but in no event more than one (1) Business Day following receipt of such net proceeds, and until the date of payment, such proceeds shall be held in trust for Agent. Any such repayment shall not reduce the Maximum Revolving Advance Amount.

(c) During any Trigger Period, in the event of any issuance or other incurrence of Indebtedness (other than Indebtedness described in clause (i) of the definition of Permitted Indebtedness) by Borrowers, each applicable Borrower shall, no later than one (1) Business Day after the receipt by Borrowers of the cash proceeds from any such issuance or incurrence of Indebtedness, repay the Advances made for its benefit and/or made directly or indirectly to it in an amount equal to one hundred percent (100%) of such cash proceeds of such incurrence or issuance of Indebtedness. Any such repayment shall not reduce the Maximum Revolving Advance Amount.

(d) During any Trigger Period, all proceeds received by Borrowers or Agent (i) under any insurance policy on account of damage or destruction of any assets or property of any Borrowers, or (ii) as a result of any taking or condemnation of any assets or property shall be applied in accordance with Section 6.6 hereof.

(a) Borrowers shall apply the proceeds of Advances to (i) repay existing indebtedness of the Borrowers on the Closing Date, (ii) pay fees and expenses relating to the Transactions, and (iii) provide for the Borrowers’ general business purposes, including working capital requirements, making Capital Expenditures, making Permitted Acquisitions, making debt payments (but not prepayments on debt other than Advances) when due and making distributions and dividends, in each case, to the extent not prohibited under this Agreement.

(b) Without limiting the generality of Section 2.21(a) above, neither the Borrowers, the Guarantors nor any other Person which may in the future become party to this Agreement or the Other Documents as a Borrower or Guarantor, intends to use nor shall they use any portion of the proceeds of the Advances, directly or indirectly, for any purpose in violation of Applicable Law.

(a) Notwithstanding anything to the contrary contained herein, in the event any Lender is a Defaulting Lender, all rights and obligations hereunder of such Defaulting Lender and of the other parties hereto shall be modified to the extent of the express provisions of this Section 2.22 so long as such Lender is a Defaulting Lender.

(b) (i) except as otherwise expressly provided for in this Section 2.22, Revolving Advances shall be made pro rata from Lenders holding Commitments which are not Defaulting Lenders based on their respective Commitment Percentages, and no Commitment Percentage of any Lender or any pro rata share of any Revolving Advances required to be advanced by any Lender shall be increased as a result of any Lender being a Defaulting Lender. Amounts received in respect of principal of any type of Revolving Advances shall be applied to reduce such type of Revolving Advances of each Lender (other than any Defaulting Lender) holding a Commitment in accordance with their Commitment Percentages; provided, that, Agent shall not be obligated to transfer to a Defaulting Lender any payments received by Agent for Defaulting Lender’s benefit, nor shall a Defaulting Lender be entitled to the sharing of any payments hereunder (including any principal, interest or fees). Amounts payable to a Defaulting Lender shall instead be paid to or retained by Agent. Agent may hold and, in its discretion, re-lend to a Borrower the amount of such payments received or retained by it for the account of such Defaulting Lender.

(ii) fees pursuant to Section 3.3 hereof shall cease to accrue in favor of such Defaulting Lender.

(iii) if any Swing Loans are outstanding or any Letters of Credit (or drawings under any Letter of Credit for which Issuer has not been reimbursed) are outstanding or exist at the time any such Lender holding a Commitment becomes a Defaulting Lender, then:

(A) Defaulting Lender’s Participation Commitment in the outstanding Swing Loans and of the Maximum Undrawn Amount of all outstanding Letters of Credit shall be reallocated among Non-Defaulting Lenders holding Commitments in proportion to the respective Commitment Percentages of such Non-Defaulting Lenders to the extent (but only to the extent) that (x) such reallocation does not cause the aggregate sum of outstanding Revolving Advances made by any such Non-Defaulting Lender holding a Commitment plus such Lender’s reallocated Participation Commitment in the outstanding Swing Loans plus such Lender’s reallocated Participation Commitment in the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit to exceed the Commitment Amount of any such Non-Defaulting Lender, and (y) no Default or Event of Default has occurred and is continuing at such time;

(B) if the reallocation described in clause (A) above cannot, or can only partially, be effected, Borrowers shall within one Business Day following notice by Agent (x) first, prepay any outstanding Swing Loans that cannot be reallocated, and (y) second, cash collateralize for the benefit of Issuer, Borrowers’ obligations corresponding to such Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit (after giving effect to any partial reallocation pursuant to clause (A) above) in accordance with Section 3.2(b) for so long as such Obligations are outstanding;

(C) if Borrowers cash collateralize any portion of such Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit pursuant to clause (B) above, Borrowers shall not be required to pay any fees to such Defaulting Lender pursuant to Section 3.2(a) with respect to such Defaulting Lender’s Commitment Percentage of Maximum Undrawn Amount of all Letters of Credit during the period such Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit are cash collateralized;

(D) if Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit is reallocated pursuant to clause (A) above, then the fees payable to Lenders holding Commitments pursuant to Section 3.2(a) shall be adjusted and reallocated to Non-Defaulting Lenders holding Commitments in accordance with such reallocation; and

(E) if all or any portion of such Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit is neither reallocated nor cash collateralized pursuant to clauses (A) or (B) above, then, without prejudice to any rights or remedies of Issuer or any other Lender hereunder, all Letter of Credit Fees payable under Section 3.2(a) with respect to such Defaulting Lender’s Commitment Percentage of the Maximum Undrawn Amount of all Letters of Credit shall be payable to the Issuer (and not to such Defaulting Lender) until (and then only to the extent that) such Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit is reallocated and/or cash collateralized; and

(iv) so long as any Lender holding a Commitment is a Defaulting Lender, Swing Loan Lender shall not be required to fund any Swing Loans and Issuer shall not be required to issue, amend or increase any Letter of Credit, unless such Issuer is satisfied that the related exposure and Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit and all Swing Loans (after giving effect to any such issuance, amendment, increase or funding) will be fully allocated to Non-Defaulting Lenders holding Commitments and/or cash collateral for such Letters of Credit will be provided by Borrowers in accordance with clause (A) and (B) above, and participating interests in any newly made Swing Loan or any newly issued or increased Letter of Credit shall be allocated among Non-Defaulting Lenders in a manner consistent with Section 2.22(b)(iii)(A) above (and such Defaulting Lender shall not participate therein).

(c) A Defaulting Lender shall not be entitled to give instructions to Agent or to approve, disapprove, consent to or vote on any matters relating to this Agreement and the Other Documents, and all amendments, waivers and other modifications of this Agreement and the Other Documents may be made without regard to a Defaulting Lender and, for purposes of the definition of “Required Lenders”, a Defaulting Lender shall not be deemed to be a Lender, to have any outstanding Advances or a Commitment Percentage provided, that this clause (c) shall not apply to the vote of a Defaulting Lender in the case of an amendment, waiver or other modification described in clauses (i) or (ii) of Section 16.2(b).

(d) Other than as expressly set forth in this Section 2.22, the rights and obligations of a Defaulting Lender (including the obligation to indemnify Agent) and the other parties hereto shall remain unchanged. Nothing in this Section 2.22 shall be deemed to release any Defaulting Lender from its obligations under this Agreement and the Other Documents, shall alter such obligations, shall operate as a waiver of any default by such Defaulting Lender hereunder, or shall prejudice any rights which any Borrower, Agent or any Lender may have against any Defaulting Lender as a result of any default by such Defaulting Lender hereunder.

(e) In the event that Agent, Borrowers, Swing Loan Lender and Issuer agree in writing that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then Agent will so notify the parties hereto, and, if such cured Defaulting Lender is a Lender holding a Commitment, then Participation Commitments of Lenders holding Commitments (including such cured Defaulting Lender) of the Swing Loans and Maximum Undrawn Amount of all outstanding Letters of Credit shall be reallocated to reflect the inclusion of such Lender’s Commitment, and on such date such Lender shall purchase at par such of the Revolving Advances of the other Lenders as Agent shall determine may be necessary in order for such Lender to hold such Revolving Advances in accordance with its Commitment Percentage.

(f) If Swing Loan Lender or Issuer has a good faith belief that any Lender holding a Commitment has defaulted in fulfilling its obligations under one or more other agreements in which such Lender commits to extend credit, Swing Loan Lender shall not be required to fund any Swing Loans and Issuer shall not be required to issue, amend or increase any Letter of Credit, unless Swing Loan Lender or Issuer, as the case may be, shall have entered into arrangements with Borrowers or such Lender, satisfactory to Swing Loan Lender or Issuer, as the case may be, to defease any risk to it in respect of such Lender hereunder.

2.23. Payment of Obligations. Agent may charge to Borrowers’ Account or Sand Tiger’s Account, as applicable, a Revolving Advance or, at the discretion of Swing Loan Lender, as a Swing Loan (i) all payments with respect to any of the Obligations or Obligations of Sand Tiger, as applicable, required hereunder (including without limitation principal payments, payments of interest, payments of Letter of Credit Fees and all other fees provided for hereunder and payments under Sections 16.5 and 16.9) as and when each such payment shall become due and payable (whether as regularly scheduled, upon or after acceleration, upon maturity or otherwise), (ii) without limiting the generality of the foregoing clause (i), (a) all amounts expended by Agent or any Lender pursuant to Sections 4.2 or 4.3 hereof and (b) all respective expenses which Agent incurs in connection with the forwarding of Advance proceeds and the establishment and maintenance of any Blocked Accounts or Depository Accounts as provided for

in Section 4.8(h), and (iii) any sums expended by Agent or any Lender due to any Borrower’s failure to perform or comply with its obligations under this Agreement or any Other Document including any Borrower’s obligations under Sections 3.3, 3.4, 4.3, 4.6, 6.4, 6.6, 6.7 and 6.8 hereof, and all amounts so charged shall be added to the Obligations or Obligations of Sand Tiger, as applicable, and shall be secured by the Collateral securing the applicable Obligations. To the extent Revolving Advances are not actually funded by the other Lenders in respect of any such amounts so charged, all such amounts so charged shall be deemed to be Revolving Advances made by and owing to Agent and Agent shall be entitled to all rights (including accrual of interest) and remedies of a Lender under this Agreement and the Other Documents with respect to such Revolving Advances.

(a) Borrowers may request that the Maximum Revolving Advance Amount be increased by (1) one or more of the current Lenders increasing their Commitment Amount (any current Lender which elects to increase its Commitment Amount shall be referred to as an “Increasing Lender”) or (2) one or more new lenders (each a “New Lender”) joining this Agreement and providing a Commitment Amount hereunder, subject to the following terms and conditions:

(i) No current Lender shall be obligated to increase its Commitment Amount and any increase in the Commitment Amount by any current Lender shall be in the sole discretion of such current Lender;

(ii) There shall exist no Event of Default or Default on the effective date of such increase after giving effect to such increase;

(iii) After giving effect to such increase, the Maximum Revolving Advance Amount shall not exceed $250,000,000;

(iv) Borrowers may not request an increase in the Maximum Revolving Advance Amount under this Section 2.24 more than three (3) times during the Term, and no single such increase in the Maximum Revolving Advance Amount shall be for an amount less than $20,000,000, and all such increases in the Maximum Revolving Advance Amount shall not exceed $80,000,000 in the aggregate;

(v) Borrowers shall deliver to Agent on or before the effective date of such increase the following documents in form and substance satisfactory to Agent: (1) certifications of their corporate secretaries with attached resolutions certifying that the increase in the Commitment Amounts has been approved by such Borrowers, (2) certificate dated as of the effective date of such increase certifying that no Default or Event of Default shall have occurred and be continuing and certifying that the representations and warranties made by each Borrower herein and in the Other Documents are true and correct in all material respects (or, if such representation and warranty is, by its terms, limited by materiality (including a Material Adverse Effect), then such representation and warranty shall be true in all respects) on and as of such date as if made on and as of such date (except to the extent any such representation or warranty specifically relates to a certain prior date), (3) such other agreements,

instruments and information (including supplements or modifications to this Agreement and/or the Other Documents executed by Borrowers as Agent reasonably deems necessary in order to document the increase to the Maximum Revolving Advance Amount and to protect, preserve and continue the perfection and priority of the liens, security interests, rights and remedies of Agent and Lenders hereunder and under the Other Documents in light of such increase, and (4) an opinion of counsel in form and substance satisfactory to Agent which shall cover such matters related to such increase as Agent may reasonably require and each Borrower hereby authorizes and directs such counsel to deliver such opinions to Agent and Lenders;

(vi) Borrowers shall execute and deliver (1) to each Increasing Lender a replacement Note or Notes reflecting the new amount of such Increasing Lender’s Commitment Amount after giving effect to the increase (and the prior Note or Notes issued to such Increasing Lender shall be deemed to be cancelled) and (2) to each New Lender a Note or Notes reflecting the amount of such New Lender’s Commitment Amount;

(vii) Any New Lender shall be subject to the reasonable satisfaction of the Agent;

(viii) Each Increasing Lender shall confirm its agreement to increase its Commitment Amount pursuant to an acknowledgement in a form reasonably acceptable to Agent, signed by it and each Borrower and delivered to Agent at least five (5) days before the effective date of such increase; and

(ix) Each New Lender shall execute a lender joinder in substantially the form of Exhibit 2.24 pursuant to which such New Lender shall join and become a party to this Agreement and the Other Documents with a Commitment Amount as set forth in such lender joinder.

(b) On the effective date of such increase, (i) Borrowers shall repay all Revolving Advances then outstanding, subject to Borrowers’ obligations under Sections 3.7, 3.9, or 3.10; provided that subject to the other conditions of this Agreement, the Borrowing Agent may request new Revolving Advances on such date and (ii) the Commitment Percentages of Lenders holding a Commitment (including each Increasing Lender and/or New Lender) shall be recalculated such that each such Lender’s Commitment Percentage is equal to (x) the Commitment Amount of such Lender divided by (y) the aggregate of the Commitment Amounts of all Lenders. Each Lender shall participate in any new Revolving Advances made on or after such date in accordance with its Commitment Percentage after giving effect to the increase in the Maximum Revolving Advance Amount and recalculation of the Commitment Percentages contemplated by this Section 2.24.

(c) On the effective date of such increase, each Increasing Lender shall be deemed to have purchased an additional/increased participation in, and each New Lender will be deemed to have purchased a new participation in, each then outstanding Letter of Credit and each drawing thereunder and each then outstanding Swing Loan in an amount equal to such Lender’s Commitment Percentage (as calculated pursuant to Section 2.24(b) above) of the Maximum Undrawn Amount of each such Letter of Credit (as in effect from time to time) and the amount of each drawing and of each such Swing Loan, respectively. As necessary to effectuate the

foregoing, each existing Lender holding a Commitment Percentage that is not an Increasing Lender shall be deemed to have sold to each applicable Increasing Lender and/or New Lender, as necessary, a portion of such existing Lender’s participations in such outstanding Letters of Credit and drawings and such outstanding Swing Loans such that, after giving effect to all such purchases and sales, each Lender holding a Commitment (including each Increasing Lender and/or New Lender) shall hold a participation in all Letters of Credit (and drawings thereunder) and all Swing Loans in accordance with their respective Commitment Percentages (as calculated pursuant to Section 2.24(b) above).

(d) On the effective date of such increase, Borrowers shall pay all reasonable out-of-pocket costs and expenses incurred by Agent and by each Increasing Lender and New Lender in connection with the negotiations regarding, and the preparation, negotiation, execution and delivery of all agreements and instruments executed and delivered by any of Agent, Borrowers and/or Increasing Lenders and New Lenders in connection with, such increase (including all fees for any supplemental or additional public filings of any Other Documents necessary to protect, preserve and continue the perfection and priority of the liens, security interests, rights and remedies of Agent and Lenders hereunder and under the Other Documents in light of such increase).

(e) Each of the parties hereto hereby agrees that, upon the effectiveness of any increase to the Commitments provided for under this Section 2.24, this Agreement shall be amended to the extent (but only to the extent) necessary to reflect the existence of such increase and the Advances provided for in connection therewith, and any such amendment may, without the consent of the other Lenders, effect such amendments to this Agreement and the Other Documents as may be necessary or appropriate, in the reasonable opinion of the Agent and Borrowers, to effectuate the provisions of this Section 2.24 and, for the avoidance of doubt, this Section 2.24(e) shall supersede any contrary provisions in Section 16.2.

2.25. Reduction of Maximum Revolving Advance Amount. Borrowing Agent may no more than once during each period of twelve months, on at least three (3) Business Days’ prior written notice received by Agent (which shall promptly advise each Lender thereof) permanently reduce the Maximum Revolving Advance Amount, minimum increments of $10,000,000 to an amount not less than the amount of the then outstanding Advances. All reductions of the Maximum Revolving Advance Amount shall be applied ratably among the Lenders according to their respective Commitment Amounts. For the avoidance of doubt, voluntary prepayments on the unutilized portion of the Maximum Revolving Advance Amount coupled with any permanent reduction of the Maximum Revolving Advance Amount effected pursuant to the immediately preceding sentence will be subject to (x) payment of (i) if such permanent reduction is effective prior to the first anniversary of the Closing Date, fees contemplated in Section 13.1 hereof and (ii) breakage costs in the case of a prepayment of LIBOR Rate Loans other than on the last day of the relevant Interest Period, and (y) any other provisions contained in this Agreement.

3.1. Interest. Interest on Advances shall be payable in arrears on the first day of each month with respect to Domestic Rate Loans and, with respect to LIBOR Rate Loans, at (a) the end of each Interest Period or (b) for LIBOR Rate Loans with an interest period in excess of

three months, at the end of each three month period during such Interest Period, provided further that all accrued and unpaid interest shall be due and payable at the end of the Term. Interest charges shall be computed on the actual principal amount of Advances outstanding during the month at a rate per annum equal to (i) with respect to Revolving Advances, the Revolving Interest Rate and (ii) with respect to Swing Loans, the Revolving Interest Rate for Domestic Rate Loans. Except as expressly provided otherwise in this Agreement, any Obligations other than the Advances that are not paid when due shall accrue interest at the Revolving Interest Rate for Domestic Rate Loans, subject to the provision of the final sentence of this Section 3.1 regarding the Default Rate. Whenever, subsequent to the date of this Agreement, the Alternate Base Rate is increased or decreased, the Revolving Interest Rate for Domestic Rate Loans shall be similarly changed without notice or demand of any kind by an amount equal to the amount of such change in the Alternate Base Rate during the time such change or changes remain in effect. The LIBOR Rate shall be adjusted with respect to LIBOR Rate Loans without notice or demand of any kind on the effective date of any change in the Reserve Percentage as of such effective date. Upon and after the occurrence of an Event of Default, and during the continuation thereof, at the option of Agent or at the direction of Required Lenders (or, in the case of any Event of Default under Section 10.7, immediately and automatically upon the occurrence of any such Event of Default without the requirement of any affirmative action by any party), the Obligations shall bear interest at the applicable Revolving Interest Rate plus two percent (2%) per annum (the “Default Rate”).

(a) Each applicable Borrower shall pay (x) to Agent, for the ratable benefit of Lenders holding Commitments, fees for each Letter of Credit for the period from and excluding the date of issuance of same to and including the date of expiration or termination, equal to the average daily face amount of each outstanding Letter of Credit multiplied by the Applicable Margin for Revolving Advances consisting of LIBOR Rate Loans, such fees to be calculated on the basis of a 360-day year for the actual number of days elapsed and to be payable quarterly in arrears on the first day of each calendar quarter and on the last day of the Term, and (y) to Issuer, a fronting fee of one quarter of one percent (0.25%) per annum times the average daily face amount of each outstanding Letter of Credit for the period from and excluding the date of issuance of same to and including the date of expiration or termination, to be payable quarterly in arrears on the first day of each calendar quarter and on the last day of the Term. (all of the foregoing fees, the “Letter of Credit Fees”). In addition, Borrowers shall pay to Agent, for the benefit of Issuer, any and all applicable administrative, issuance, amendment, payment and negotiation charges with respect to Letters of Credit and all fees and expenses as agreed upon by Issuer and the Borrowing Agent in connection with any Letter of Credit, including in connection with the opening, amendment or renewal of any such Letter of Credit and any acceptances created thereunder, all such charges, fees and expenses, if any, to be payable on demand. All such charges shall be deemed earned in full on the date when the same are due and payable hereunder and shall not be subject to rebate or pro-ration upon the termination of this Agreement for any reason. Any such charge in effect at the time of a particular transaction shall be the charge for that transaction, notwithstanding any subsequent change in Issuer’s prevailing charges for that type of transaction. Upon and after the occurrence of an Event of Default, and during the continuation thereof, at the option of Agent or at the direction of Required Lenders (or, in the

case of any Event of Default under Section 10.7, immediately and automatically upon the occurrence of any such Event of Default without the requirement of any affirmative action by any party), the Letter of Credit Fees described in clause (x) of this Section 3.2(a) shall be increased by an additional two percent (2.0%) per annum.

(b) At any time following the occurrence and during the continuance of an Event of Default, at the option of Agent or at the direction of Required Lenders (or, in the case of any Event of Default under Section 10.7, immediately and automatically upon the occurrence of such Event of Default, without the requirement of any affirmative action by any party), or upon the expiration of the Term or any other termination of this Agreement (and also, if applicable, in connection with any mandatory prepayment under Section 2.20), Borrowers will cause cash to be deposited and maintained in an account with Agent, as cash collateral, in an amount equal to one hundred and five percent (105%) of the Maximum Undrawn Amount of their respective outstanding Letters of Credit, and each Borrower hereby irrevocably authorizes Agent, in its discretion, on such Borrower’s behalf and in such Borrower’s name, to open such an account and to make and maintain deposits therein, or in an account opened by such Borrower, in the amounts required to be made by such Borrower, out of the proceeds of Receivables or other Collateral or out of any other funds of such Borrower coming into any Lender’s possession at any time. Agent may, in its discretion, invest such cash collateral (less applicable reserves) in such short-term money-market items as to which Agent and such Borrower mutually agree (or, in the absence of such agreement, as Agent may reasonably select) and the net return on such investments shall be credited to such account and constitute additional cash collateral, or Agent may (notwithstanding the foregoing) establish the account provided for under this Section 3.2(b) as a non-interest bearing account and in such case Agent shall have no obligation (and Borrowers hereby waive any claim) under Article 9 of the Uniform Commercial Code or PPSA or under any other Applicable Law to pay interest on such cash collateral being held by Agent. No Borrower may withdraw amounts credited to any such account except upon the occurrence of all of the following: (x) payment and performance in full of all Obligations; (y) expiration of all Letters of Credit; and (z) termination of this Agreement. Borrowers hereby assign, pledge and grant to Agent, for its benefit and the ratable benefit of Issuer, Lenders and each other Secured Party, a continuing security interest in and to and Lien on any such cash collateral and any right, title and interest of Borrowers in any deposit account, securities account or investment account into which such cash collateral may be deposited from time to time to secure the Obligations or Sand Tiger’s Obligations, as applicable, specifically including all Obligations with respect to any Letters of Credit. Borrowers agree that upon the coming due of any Reimbursement Obligations (or any other Obligations, including Obligations for Letter of Credit Fees) with respect to the Letters of Credit, Agent may, subject to Section 16.19, use such cash collateral to pay and satisfy such Obligations.

3.3. Facility Fee. If, for any calendar quarter during the Term, the average daily unpaid balance of the sum of Revolving Advances (for purposes of this computation, Swing Loans shall be deemed to be Revolving Advances made by PNC as a Lender) plus Swing Loans plus the Maximum Undrawn Amount of all outstanding Letters of Credit for each day of such calendar quarter does not equal the Maximum Revolving Advance Amount, then Borrowers shall pay to Agent, for the ratable benefit of Lenders holding the Commitments based on their Commitment Percentages, a fee at a rate equal to three-eighths of one percent (0.375%) per

annum on the amount by which the Maximum Revolving Advance Amount exceeds such average daily unpaid balance (the “Facility Fee”). Such Facility Fee shall be payable to Agent in arrears on the first day of each calendar quarter with respect to the previous calendar quarter.

(a) Borrowers (other than Sand Tiger) shall pay the amounts required to be paid in the Fee Letter in the manner and at the times required by the Fee Letter.

(b) All of the fees and reasonable out-of-pocket costs and expenses of any appraisals conducted pursuant to Section 4.7 hereof shall be paid for when due, in full and without deduction, off-set or counterclaim by Borrowers.

3.5. Computation of Interest and. Interest and fees hereunder shall be computed on the basis of a year of 365 days or 366 days, as applicable (360 days with respect to LIBOR Rate Loans), with respect to Base Rate Loans and for the actual number of days elapsed. If any payment to be made hereunder becomes due and payable on a day other than a Business Day, the due date thereof shall be extended to the next succeeding Business Day and interest thereon shall be payable at the Revolving Interest Rate for Domestic Rate Loans during such extension. For purposes of the Interest Act (Canada): (i) whenever any interest or fee under this Agreement is calculated on the basis of a period of time other than a calendar year, such rate used in such calculation, when expressed as an annual rate, is equivalent to (x) such rate, multiplied by (y) the actual number of days in the calendar year in which the period for which such interest or fee is calculated ends, and divided by (z) the number of days in such period of time; (ii) the principle of deemed reinvestment of interest shall not apply to any interest calculation under this Agreement; and (iii) the rates of interest stipulated in this Agreement are intended to be nominal rates and not effective rates or yields.

3.6. Maximum Charges. In no event whatsoever shall interest and other charges charged hereunder exceed the highest rate permissible under Applicable Law. In the event interest and other charges as computed hereunder would otherwise exceed the highest rate permitted under Applicable Law: (i) the interest rates hereunder will be reduced to the maximum rate permitted under Applicable Law; (ii) such excess amount shall be first applied to any unpaid principal balance owed by Borrowers; and (iii) if the then remaining excess amount is greater than the previously unpaid principal balance, Lenders shall promptly refund such excess amount to Borrowers and the provisions hereof shall be deemed amended to provide for such permissible rate. Notwithstanding anything to the contrary contained in this Agreement or in any Other Document, all agreements which either now are or which shall become agreements among Credit Parties, Agent and Lenders are hereby limited so that in no contingency or event whatsoever shall the total liability for payments in the nature of interest, additional interest and other charges exceed the applicable limits imposed by any applicable usury laws. If any payments in the nature of interest, additional interest and other charges made under this Agreement or any Other Document are held to be in excess of the limits imposed by any applicable usury laws, it is agreed that any such amount held to be in excess shall be considered payment of principal hereunder, and the indebtedness evidenced hereby shall be reduced by such amount so that the total liability for payments in the nature of interest, additional interest and other charges shall not exceed the applicable limits imposed by any applicable usury laws, in compliance with the

desires of Credit Parties and Agent. The foregoing provisions shall never be superseded or waived and shall control every other provision of this Agreement or any Other Document and all agreements among Borrowers and Agent and Lenders, or their respective successors and assigns. If the applicable state or federal law is amended in the future to allow a greater rate of interest to be charged under this Agreement than is presently allowed by applicable state or federal law, then the limitation of interest hereunder shall be increased to the maximum rate of interest allowed by applicable state or federal law as amended, which increase shall be effective hereunder on the effective date of such amendment, and all interest charges owing to Lender by reason thereof shall be payable in accordance with Section 3.1 of this Agreement. If by operation of this provision, Borrowers would be entitled to a refund of interest paid pursuant to this Agreement, each Lender agrees that it shall pay to Borrowers upon Agent’s request such Lender’s Commitment Percentage, of such interest to be refunded, as determined by Agent. If any provision of this Agreement or Other Documents would oblige any Borrower to make any payment of interest or other amount payable to any Lender in an amount or calculated at a rate which would be prohibited by law or would result in a receipt by that Lender of “interest” at a “criminal rate” (as such terms are construed under the Criminal Code (Canada)), then, notwithstanding such provision, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by Applicable Law or so result in a receipt by that Lender of “interest” at a “criminal rate”, such adjustment to be effected, to the extent necessary (but only to the extent necessary), as follows: first, by reducing the amount or rate of interest, and, thereafter, by reducing any fees, commissions, costs, expenses, premiums and other amounts required to be paid to the affected Lender which would constitute interest for purposes of section 347 of the Criminal Code (Canada).

3.7. Increased Costs. In the event that any Applicable Law or any Change in Law or compliance by any Lender (for purposes of this Section 3.7, the term “Lender” shall include Agent, Swing Loan Lender, any Issuer or Lender and any corporation or bank controlling Agent, Swing Loan Lender, any Lender or Issuer and the office or branch where Agent, Swing Loan Lender, any Lender or Issuer (as so defined) makes or maintains any LIBOR Rate Loans) with any request or directive (whether or not having the force of law) from any central bank or other financial, monetary or other authority, shall:

(a) subject Agent, Swing Loan Lender, any Lender or Issuer to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any LIBOR Rate Loan, or change the basis of taxation of payments to Agent, Swing Loan Lender, such Lender or Issuer in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 3.10 and the imposition of, or any change in the rate of, any Excluded Tax payable by Agent, Swing Loan Lender, such Lender or the Issuer);

(b) impose, modify or deem applicable any reserve, special deposit, assessment, special deposit, compulsory loan, insurance charge or similar requirement against assets held by, or deposits in or for the account of, advances or loans by, or other credit extended by, any office of Agent, Swing Loan Lender, Issuer or any Lender, including pursuant to Regulation D of the Board of Governors of the Federal Reserve System; or

(c) impose on Agent, Swing Loan Lender, any Lender or Issuer or the London interbank LIBOR market any other condition, loss or expense (other than Taxes) affecting this Agreement or any Other Document or any Advance made by any Lender, or any Letter of Credit or participation therein;

and the result of any of the foregoing is to increase the cost to Agent, Swing Loan Lender, any Lender or Issuer of making, converting to, continuing, renewing or maintaining its Advances hereunder or to reduce the amount of any payment (whether of principal, interest or otherwise) in respect of any of the Advances, then, in any case Borrowers shall promptly pay Agent, Swing Loan Lender, such Lender or Issuer, upon its demand, such additional amount as will compensate Agent, Swing Loan Lender or such Lender or Issuer for such additional cost or such reduction, as the case may be, provided that the foregoing shall not apply to increased costs which are reflected in the LIBOR Rate, as the case may be (provided, that Sand Tiger shall only be liable for any such costs or expenses attributable to Sand Tiger’s Obligations). Agent, Swing Loan Lender, such Lender or Issuer shall certify the amount of such additional cost or reduced amount to Borrowing Agent within three hundred sixty (360) days of the occurrence thereof, and such certification shall be conclusive absent manifest error.

3.8. Basis For Determining Interest Rate Inadequate or Unfair. In the event that Agent or any Lender shall have determined that:

(a) reasonable means do not exist for ascertaining the LIBOR Rate applicable pursuant to Section 2.2 hereof for any Interest Period; or

(b) Dollar deposits in the relevant amount and for the relevant maturity are not available in the London interbank LIBOR market, with respect to an outstanding LIBOR Rate Loan, a proposed LIBOR Rate Loan, or a proposed conversion of a Domestic Rate Loan into a LIBOR Rate Loan; or

(c) the making, maintenance or funding of any LIBOR Rate Loan has been made impracticable or unlawful by compliance by Agent or such Lender in good faith with any Applicable Law or any interpretation or application thereof by any Governmental Body or with any request or directive of any such Governmental Body (whether or not having the force of law),

then Agent shall give Borrowing Agent prompt written or telephonic notice of such determination. If such notice is given, (i) any such requested LIBOR Rate Loan shall be made as a Domestic Rate Loan, unless Borrowing Agent shall notify Agent no later than 1:00 p.m. two (2) Business Days prior to the date of such proposed borrowing, that its request for such borrowing shall be cancelled or made as an unaffected type of LIBOR Rate Loan, (ii) any Domestic Rate Loan or LIBOR Rate Loan which was to have been converted to an affected type of LIBOR Rate Loan shall be continued as or converted into a Domestic Rate Loan, or, if Borrowing Agent shall notify Agent, no later than 1:00 p.m. two (2) Business Days prior to the proposed conversion, shall be maintained as an unaffected type of LIBOR Rate Loan, and (iii) any outstanding affected LIBOR Rate Loans shall be converted into a Domestic Rate Loan, or, if Borrowing Agent shall notify Agent, no later than 1:00 p.m. two (2) Business Days prior to the last Business Day of the then current Interest Period applicable to such affected LIBOR Rate

Loan, shall be converted into an unaffected type of LIBOR Rate Loan, on the last Business Day of the then current Interest Period for such affected LIBOR Rate Loans (or sooner, if any Lender cannot continue to lawfully maintain such affected LIBOR Rate Loan). Until such notice has been withdrawn, Lenders shall have no obligation to make an affected type of LIBOR Rate Loan or maintain outstanding affected LIBOR Rate Loans and no Borrower shall have the right to convert a Domestic Rate Loan or an unaffected type of LIBOR Rate Loan into an affected type of LIBOR Rate Loan.

(a) In the event that Agent, Swing Loan Lender or any Lender shall have determined that any Applicable Law or guideline regarding capital adequacy or liquidity requirements, or any Change in Law or any change in the interpretation or administration thereof by any Governmental Body, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by Agent, Swing Loan Lender, Issuer or any Lender (for purposes of this Section 3.9, the term “Lender” shall include Agent, Swing Loan Lender, Issuer or any Lender and any corporation or bank controlling Agent, Swing Loan Lender or any Lender and the office or branch where Agent, Swing Loan Lender or any Lender (as so defined) makes or maintains any LIBOR Rate Loans) with any request or directive regarding capital adequacy or liquidity requirements (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on Agent within three hundred sixty (360) days after such request or directive, Swing Loan Lender or any Lender’s capital as a consequence of its obligations hereunder (including the making of any Swing Loans) to a level below that which Agent, Swing Loan Lender or such Lender could have achieved but for such adoption, change or compliance (taking into consideration Agent’s, Swing Loan Lender’s and each Lender’s policies with respect to capital adequacy), then, from time to time, Borrowers shall pay upon demand to Agent, Swing Loan Lender or such Lender such additional amount or amounts as will compensate Agent, Swing Loan Lender or such Lender for such reduction (provided, that Sand Tiger shall only be liable for any such amounts attributable to Sand Tiger’s Obligations). In determining such amount or amounts, Agent, Swing Loan Lender or such Lender may use any reasonable averaging or attribution methods. The protection of this Section 3.9 shall be available to Agent, Swing Loan Lender and each Lender regardless of any possible contention of invalidity or inapplicability with respect to the Applicable Law, rule, regulation, guideline or condition.

(b) A certificate of Agent, Swing Loan Lender or such Lender setting forth such amount or amounts as shall be necessary to compensate Agent, Swing Loan Lender or such Lender with respect to Section 3.9(a) hereof when delivered to Borrowing Agent shall be conclusive absent manifest error.

(a) Any and all payments by or on account of any Obligations hereunder or under any Other Document shall be made free and clear of and without reduction or withholding for any Taxes except to the extent required by Applicable Law; provided that if the Borrowers shall be required by Applicable Law to deduct any Taxes from such payments, then (i) if such Taxes are Indemnified Taxes, the sum payable shall be increased as necessary so that after

making all required deductions for Indemnified Taxes (including deductions for Indemnified Taxes applicable to additional sums payable under this Section 3.10) the Recipient receives an amount equal to the sum it would have received had no such deductions for Indemnified Taxes been made, (ii) the Borrowers or other applicable withholding agent shall make such deductions and (iii) the Borrowers or other applicable withholding agent shall timely pay the full amount deducted to the relevant Governmental Body in accordance with Applicable Law.

(b) Without limiting the provisions of Section 3.10(a) above, Borrowers shall timely pay any Other Taxes to the relevant Governmental Body in accordance with Applicable Law.

(c) The Borrowers shall indemnify each Recipient, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 3.10) paid by such Recipient, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Body. A certificate as to the amount of such payment or liability delivered to the Borrowers by any Recipient (with a copy to Agent) shall be conclusive absent manifest error (provided, Sand Tiger shall only be liable for any such Taxes attributable to Sand Tiger’s Obligations).

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by any Borrower to a Governmental Body, the Borrowers shall deliver to Agent the original or a certified copy of a receipt issued by such Governmental Body evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to Agent.

(e) Any Recipient that is entitled to an exemption from or reduction of any withholding Tax under the law of the jurisdiction in which any Borrower is resident for Tax purposes, or under any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any Other Document shall deliver to the Borrowers (with a copy to Agent), at the time or times prescribed by Applicable Law or reasonably requested by the Borrowers or Agent, such properly completed and executed documentation prescribed by Applicable Law as will permit such payments to be made without withholding or at a reduced rate of withholding. Notwithstanding the submission of such documentation claiming a reduced rate of or exemption from U.S. withholding Tax, Agent shall be entitled to withhold United States federal income Taxes at the full 30% withholding rate if in its reasonable judgment it is required to do so under the due diligence requirements imposed upon a withholding agent under § 1.1441-7(b) of the United States Income Tax Regulations or other Applicable Law. Further, Agent is indemnified under § 1.1461-1(e) of the United States Income Tax Regulations against any claims and demands of any Recipient for the amount of any Tax it deducts and withholds in accordance with regulations under § 1441 of the Code. In addition, any Recipient, if requested by the Borrowers or Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrowers or Agent as will enable the Borrowers or Agent to determine whether or not such Recipient is subject to backup withholding or information reporting requirements. Without limiting the generality of the foregoing, each Recipient shall deliver to the Borrowers and Agent (in such number of copies as shall be requested by the recipient) on or

prior to the date on which such Recipient becomes a Recipient under this Agreement (and from time to time thereafter upon the request of the Borrowers or the Agent, but only if such Recipient is legally entitled to do so), whichever of the following is applicable:

(i) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party, (x) with respect to payments of interest under this Agreement or any Other Document, two (2) duly completed valid originals of IRS Form W¬8BEN establishing an exemption from, or reduction of, United States federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under this Agreement or any Other Document, IRS Form W-8BEN establishing an exemption from, or reduction of, United States federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty,

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit 3.10-1 to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrowers within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) two duly completed valid originals of IRS Form W-8BEN,

(iv) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a certificate substantially in the form of Exhibit 3.10-2 or Exhibit 3.10-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a certificate substantially in the form of Exhibit 3.10-4 on behalf of each such direct and indirect partner,

(v) any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by Applicable Law to permit the Borrowers to determine the withholding or deduction required to be made, or

(vi) in the case of a Recipient that is a United States person within the meaning of section 7701(a)(30) of the Code, two duly completed valid (2) originals of an IRS Form W-9 or any other form prescribed by Applicable Law certifying that such Recipient is exempt from United States federal backup withholding tax.

(f) If a payment made to a Recipient under this Agreement or any Other Document would be subject to U.S. Federal withholding Tax imposed by FATCA if such Person fails to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Recipient shall deliver to the Agent (in the case of Swing Loan Lender, a Lender, Participant or Issuer) and the Borrowers (i) a

certification signed by the chief financial officer, principal accounting officer, treasurer or controller of such Person, and (i) such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such other documentation reasonably requested by the Agent or any Borrower sufficient for Agent and the Borrowers to comply with their obligations under FATCA and to determine that such Recipient has complied with its obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (f), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(c) Subject to Section 16.5, each Recipient agrees that if any form or certification it previously delivered pursuant to clauses (e) or (f) above expires or becomes inaccurate in any respect, or if Borrowing Agent or Agent should request an updated form or certification, it shall update such form or certification or promptly notify the Borrowing Agent and the Agent in writing of its legal inability to so.

(d) If Agent, Swing Loan Lender, a Lender, a Participant or Issuer determines, in its sole discretion, that it has received a refund of any Indemnified Taxes or Other Taxes as to which it has been indemnified by Borrowers or with respect to which Borrowers have paid additional amounts pursuant to this Section, it shall pay to Borrowers an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by Borrowers under this Section with respect to the Indemnified Taxes or Other Taxes giving rise to such refund); net of all out-of-pocket expenses of the Agent, Swing Loan Lender, such Lender, Participant, or the Issuer, as the case may be, and without interest (other than any interest paid by the relevant Governmental Body with respect to such refund), provided that Borrowers, upon the request of Agent, Swing Loan Lender, such Lender, Participant, or Issuer, agrees to repay the amount paid over to Borrowers (plus any penalties, interest or other charges imposed by the relevant Governmental Body) to Agent, Swing Loan Lender, such Lender, Participant or the Issuer in the event Agent, Swing Loan Lender, such Lender, Participant or the Issuer is required to repay such refund to such Governmental Body. This Section shall not be construed to require Agent, Swing Loan Lender, any Lender, Participant, or Issuer to make available its tax returns (or any other information relating to its taxes that it deems confidential) to Borrowers or any other Person.

3.11. Replacement of Lenders. If any Lender (an “Affected Lender”) (a) makes demand upon Borrowers for (or if Borrowers are otherwise required to pay) amounts pursuant to Section 3.7, 3.9 or 3.10 hereof, (b) is unable to make or maintain LIBOR Rate Loans as a result of a condition described in Section 2.2(h) hereof, (c) is a Defaulting Lender, or (d) denies any consent requested by the Agent pursuant to Section 16.2(b) hereof, Borrowers may, within forty-five (45) days of receipt of such demand, notice (or the occurrence of such other event causing Borrowers to be required to pay such compensation or causing Section 2.2(h) hereof to be applicable), or such Lender becoming a Defaulting Lender or denial of a request by the Agent pursuant to Section 16.2(b) hereof, as the case may be, by notice (a “Replacement Notice”) in writing to the Agent and such Affected Lender (i) request the Affected Lender to cooperate with Borrowers in obtaining a replacement Lender satisfactory to the Agent and Borrowers (the “Replacement Lender”); (ii) request the non-Affected Lenders to acquire and assume all of the Affected Lender’s Advances and its Commitment Percentage, as provided herein, but none of

such Lenders shall be under any obligation to do so; or (iii) propose a Replacement Lender subject to approval by the Agent in its good faith business judgment; provided, (x) in the case of any such replacement resulting from a claim for compensation under Section 3.7, 3.9 or 3.10 hereof, such replacement will result in a reduction of such compensation from the Replacement Lender at the time of such replacement; and (y) such replacement does not conflict with applicable law. If any satisfactory Replacement Lender shall be obtained, and/or if any one or more of the non-Affected Lenders shall agree to acquire and assume all of the Affected Lender’s Advances and its Commitment Percentage, then such Affected Lender shall assign, in accordance with Section 16.3 hereof, all of its Advances and its Commitment Percentage, and other rights and obligations under this Loan Agreement and the Other Documents to such Replacement Lender or non-Affected Lenders, as the case may be, in exchange for payment of the principal amount so assigned and all interest and fees accrued on the amount so assigned, plus all other Obligations then due and payable to the Affected Lender. If any Affected Lender does not execute an assignment in accordance with Section 16.3 within five (5) Business Days after receipt of notice to do so by Agent or Borrowing Agent, then Agent shall be entitled (but not obligated) to execute such assignment on behalf of such Affected Lender, which shall be effective for purposes of Section 16.3 and this Agreement.

4.1. Security Interest in the Collateral. To secure the prompt payment and performance to Agent, Issuer and each Lender (and each other holder of any Obligations) of the Obligations, each Borrower hereby assigns, pledges and grants to Agent for its benefit and for the ratable benefit of each Lender, Issuer and each other Secured Party, a continuing security interest in and to and Lien on all of its Collateral, whether now owned or existing or hereafter created, acquired or arising and wheresoever located; provided, however, anything contained herein or in any other document to the contrary notwithstanding, the Lien granted by Sand Tiger pursuant to this Section 4.1 shall only secure (or be deemed to secure) the Sand Tiger Obligations. Each Borrower shall mark its books and records as may be necessary or appropriate to evidence, protect and perfect Agent’s security interest and shall cause its financial statements to reflect such security interest. Each Borrower shall provide Agent with written notice of all commercial tort claims promptly upon the occurrence of any events giving rise to any such claim(s) (regardless of whether legal proceedings have yet been commenced), such notice to contain a brief description of the claim(s), the events out of which such claim(s) arose and the parties against which such claims may be asserted and, if applicable in any case where legal proceedings regarding such claim(s) have been commenced, the case title together with the applicable court and docket number. Upon delivery of each such notice, such Borrower shall be deemed to thereby grant to Agent a security interest and lien in and to such commercial tort claims described therein and all proceeds thereof. Each Borrower shall provide Agent with written notice promptly upon becoming the beneficiary under any letter of credit or otherwise obtaining any right, title or interest in any letter of credit rights, and at Agent’s request shall take such actions as Agent may reasonably request for the perfection of Agent’s security interest therein.

4.2. Perfection of Security Interest. Except for any Collateral disposed of in accordance with Section 7.1, each Borrower shall take all action that may be necessary that

Agent may request, so as at all times to maintain the validity, perfection, enforceability and priority of Agent’s security interest in and Lien on the Collateral or to enable Agent to protect, exercise or enforce its rights hereunder and in the Collateral, including, but not limited to, (i) promptly discharging all Liens other than Permitted Encumbrances, (ii) obtaining Lien Waiver Agreements required under this Agreement, (iii) delivering to Agent, endorsed or accompanied by such instruments of assignment as Agent may specify, and stamping or marking, in such manner as Agent may specify, any and all chattel paper, instruments, letters of credits and advices thereof and documents evidencing or forming a part of the Collateral, (iv) entering into warehousing, lockbox, customs and freight agreements and other custodial arrangements satisfactory to Agent, and (v) executing and delivering financing statements, control agreements, instruments of pledge, mortgages, notices and assignments, in each case in form and substance satisfactory to Agent, relating to the creation, validity, perfection, maintenance or continuation of Agent’s security interest and Lien under the Uniform Commercial Code, PPSA or other Applicable Law. By its signature hereto, each Borrower hereby authorizes Agent to file against such Borrower, one or more financing, continuation or amendment statements pursuant to the Uniform Commercial Code or PPSA in form and substance satisfactory to Agent (which statements may have a description of collateral which is broader than that set forth herein, including without limitation a description of Collateral as “all assets” and/or “all personal property” of any Borrower). All reasonable out-of-pocket charges, expenses and fees Agent may incur in doing any of the foregoing, and any local taxes relating thereto, shall be charged to Borrowers’ Account or Sand Tiger’s Account, as applicable, as a Revolving Advance of a Domestic Rate Loan and added to the Obligations, or, at Agent’s option, shall be paid by the applicable Borrowers to Agent for its benefit and for the ratable benefit of Lenders immediately upon demand.

4.3. Preservation of Collateral. Each Borrower will safeguard and protect all Collateral for Agent’s general account. In addition to the rights and remedies set forth in Section 11.1 hereof, Agent: (a) may at any time take such steps as Agent deems necessary in the exercise of its Permitted Discretion to protect Agent’s interest in and to preserve the Collateral, including after the occurrence and during the continuance of an Event of Default, the hiring of such security guards or the placing of other security protection measures as Agent may deem appropriate; (b) after the occurrence and during the continuance of an Event of Default, may employ and maintain at any of each Borrower’s premises a custodian who shall have full authority to do all acts necessary to protect Agent’s interests in the Collateral; (c) after the occurrence and during the continuance of a Default or Event of Default, may lease warehouse facilities to which Agent may move all or part of the Collateral; (d) after the occurrence and during the continuance of an Event of Default, may use any Borrower’s owned or leased lifts, hoists, trucks and other facilities or equipment for handling or removing the Collateral; and (e) subject to Section 4.10 hereof, shall have, and is hereby granted, a right of ingress and egress to the places where the Collateral is located, and may proceed over and through any of Borrowers’ owned or leased property, subject to the rights of the landlords of any leased Real Property and, if applicable, the terms of any applicable Lien Waiver Agreement. Subject to the other provisions of this Agreement regarding Borrowers’ maintenance of Collateral, each Borrower shall cooperate with all of Agent’s efforts to preserve the Collateral and will take such actions to preserve the Collateral as Agent may direct in its Permitted Discretion. Subject to Section 16.9 and Section 6.19, all of Agent’s reasonable out-of-pocket expenses of preserving the Collateral,

including any such expenses relating to the bonding of a custodian, shall be charged to Borrowers’ Account or Sand Tiger’s Account, as applicable, as a Revolving Advance maintained as a Domestic Rate Loan and added to the Obligations.

(a) With respect to the Collateral, at the time the Collateral becomes subject to Agent’s security interest: (i) each Borrower is, and shall remain the sole owner of and fully authorized and able to sell, transfer, pledge and/or grant a first priority security interest (subject only to Permitted Encumbrances that have priority as a matter of Applicable Law) in each and every item of its respective Collateral; (ii) except for Permitted Encumbrances the Collateral shall be free and clear of all Liens; and (iii) each Borrower’s Equipment and Inventory shall be located as set forth on Schedule 4.4 (as updated from time to time pursuant to each Compliance Certificate delivered pursuant to Section 9.3) and shall not be removed from such location(s) without the prior written consent of Agent, except (1) as may be moved from one location on such schedule to another location on such schedule, (2) Equipment and Inventory in-transit, (3) Equipment out in the ordinary course of business (4) the sale, transfer or disposition of assets permitted under this Agreement and (5) as may be located at locations not set forth on Schedule 4.4 to the extent the aggregate value of Equipment and Inventory at such locations does not exceed $1,000,000 for any one location.

(b) (i) Schedule 4.4 hereto contains a correct and complete list, as of the Closing Date, of the legal names and addresses of each warehouse at which Inventory having a value in excess of $1,000,000 of any Borrower is stored; none of the receipts received by any Borrower from any warehouse states that the goods covered thereby are to be delivered to bearer or to the order of a named Person or to a named Person and such named Person’s assigns; (ii) Schedule 4.4 hereto sets forth a correct and complete list as of the Closing Date of (A) each place of business of each Borrower and (B) the chief executive office of each Borrower; and (iii) Schedule 4.4 hereto sets forth a correct and complete list as of the Closing Date of the location, by state and street address, of all Real Property owned or leased by each Borrower, together with the names of any landlords.

4.5. Defense of Agent’s and Lenders’ Interests. Until (a) payment and performance in full of all of the Obligations (including, without limitation, the cash collateralization of all issued and outstanding Letters of Credit, but excluding contingent indemnification Obligations for which no claim giving rise thereto has been asserted) and (b) termination of this Agreement and the Other Documents, Agent’s security interests in the Collateral shall continue in full force and effect except to the extent released pursuant to the terms of this Agreement. Each Borrower shall use all commercially reasonable efforts to defend Agent’s interests in the Collateral against any and all Persons whatsoever. At any time following demand by Agent for payment of all Obligations after the occurrence of and during the continuance of an Event of Default, Agent shall have the right to take possession of the indicia of the Collateral and the Collateral in whatever physical form contained, including: labels, stationery, documents, instruments and advertising materials. If Agent exercises this right to take possession of the Collateral, after the occurrence of and during the continuance of an Event of Default, Borrowers shall, upon demand, assemble it in the best manner possible and make it available to Agent at a place reasonably convenient to Agent. In addition, with respect to all Collateral, Agent and Lenders shall be

entitled to all of the rights and remedies set forth herein and further provided by the Uniform Commercial Code, PPSA or other Applicable Law. Each Borrower shall, and Agent may, at its option after the occurrence and during the continuance of an Event of Default, instruct all suppliers, carriers, forwarders, warehousers or others receiving or holding cash, checks, Inventory, documents or instruments in which Agent holds a security interest to deliver same to Agent and/or subject to Agent’s order and if they shall come into any Borrower’s possession, they, and each of them, shall be held by such Borrower in trust as Agent’s trustee, and such Borrower will immediately deliver them to Agent in their original form together with any necessary endorsement.

4.6. Inspection of Premises. At all reasonable times and from time to time as often as Agent shall elect in its sole discretion, Agent and each Lender shall have full access to and the right to audit, check, inspect and make abstracts and copies from each Borrower’s books, records, audits, correspondence and all other papers relating to the Collateral and the operation of each Borrower’s business. Agent, any Lender and their agents may enter upon any premises of any Borrower at any time during business hours and at any other reasonable time, and, if an Event of Default exists, from time to time as often as Agent shall elect in its sole discretion, for the purpose of inspecting the Collateral and any and all records pertaining thereto and the operation of such Borrower’s business.

4.7. Appraisals. Agent may, in its sole discretion, exercised in a commercially reasonable manner, up to twice during any fiscal year after the Closing Date and from time to time, engage the services of an independent appraisal firm or firms of reputable standing, satisfactory to Agent, for the purpose of appraising the then current values of Borrowers’ assets which will be identified by Borrowers to be included in the calculation of the Formula Amount. Absent the occurrence and continuance of an Event of Default at such time, Agent shall consult with Borrowers as to the identity of any such firm. In the event the value of Borrowers’ Inventory or Eligible Equipment, as so determined pursuant to such appraisal, is less than anticipated by Agent or Lenders, such that the Revolving Advances are in excess of such Advances permitted hereunder, then, promptly upon Agent’s demand for same, Borrowers shall make mandatory prepayments of the then outstanding Revolving Advances so as to eliminate the excess Advances.

(a) Nature of Receivables. Each of the Receivables at any time reported to Agent (whether pursuant to Section 9.2 or otherwise) shall, except as noted therein, be a bona fide and valid account representing a bona fide indebtedness incurred by the Customer therein named, for a fixed sum (subject to customary discounts or reductions permitted in the ordinary course of business and in accordance with past practices) as set forth in the invoice relating thereto (provided immaterial or unintentional invoice errors shall not be deemed to be a breach hereof) with respect to an absolute sale or lease and delivery of goods upon stated terms of a Borrower, or work, labor or services theretofore rendered by a Borrower as of the date each Receivable is created. Same shall be due and owing in accordance with the applicable Borrower’s standard terms of sale without dispute, setoff or counterclaim except as may be stated on the accounts receivable schedules delivered by Borrowers to Agent.

(b) Each Customer, to the best of each Borrower’s knowledge, as of the date each Receivable is created, is and will be solvent and able to pay all Receivables on which the Customer is obligated in full when due. With respect to such Customers of any Borrower who are not solvent, such Borrower has set up on its books and in its financial records bad debt reserves adequate to cover such Receivables.

(c) Each Borrower’s chief executive office is located as set forth on Schedule 4.4. Until written notice is given to Agent by Borrowing Agent of any other office at which any Borrower keeps its records pertaining to Receivables, all such records shall be kept at such executive office.

(d) Borrowers shall instruct their Customers to deliver all remittances upon Receivables (whether paid by check or by wire transfer of funds) to such Blocked Account(s) and/or Depository Accounts (and any associated lockboxes) as Agent shall designate from time to time as contemplated by Section 4.8(h) or as otherwise agreed to from time to time by Agent. Notwithstanding the foregoing, to the extent any Borrower directly receives any remittances upon Receivables, such Borrower shall, at such Borrower’s sole cost and expense, but on Agent’s behalf and for Agent’s account, collect as Agent’s property and in trust for Agent all amounts received on Receivables, and shall not commingle such collections with any Borrower’s funds or use the same except to pay Obligations, and shall as soon as possible and in any event no later than one (1) Business Day after the receipt thereof (i) in the case of remittances paid by check, deposit all such remittances in their original form (after supplying any necessary endorsements) and (ii) in the case of remittances paid by wire transfer of funds, transfer all such remittances, in each case, into such Blocked Accounts(s) and/or Depository Account(s). Each Borrower shall deposit in the applicable Blocked Account and/or Depository Account or, upon request by Agent during a Trigger Period, deliver to Agent, in original form and on the date of receipt thereof, all checks, drafts, notes, money orders, acceptances, cash and other evidences of Indebtedness.

(e) At any time following the occurrence, and during the continuance of, an Event of Default or a Default, Agent shall have the right to send notice of the assignment of, and Agent’s security interest in and Lien on, the Receivables to any and all Customers or any third party holding or otherwise concerned with any of the Collateral. At any time after the occurrence and during the continuance of an Event of Default, Agent shall have the sole right to collect the Receivables, take possession of the Collateral, or both. Agent’s actual collection expenses, including, but not limited to, stationery and postage, telephone, facsimile, telegraph, secretarial and clerical expenses and the salaries of any collection personnel used for collection, may be charged to Borrowers’ Account and added to the Obligations.

(f) Power of Agent to Act on Borrowers’ Behalf. Upon and during the continuance of an Event of Default (except to the extent otherwise agreed in any treasury management agreement between any Borrower and Agent), Agent shall have the right to receive, endorse, assign and/or deliver in the name of Agent or any Borrower any and all checks, drafts and other instruments for the payment of money relating to the Receivables, and each Borrower hereby waives notice of presentment, protest and non-payment of any instrument so endorsed. Each Borrower hereby constitutes Agent or Agent’s designee as such Borrower’s attorney with power (i) to endorse such Borrower’s name upon any notes, acceptances, checks, drafts, money

orders or other evidences of payment or Collateral upon and during the continuance of an Event of Default (except to the extent otherwise agreed in treasury management agreement between any Borrower and Agent); (ii) to sign such Borrower’s name on any invoice or bill of lading relating to any of the Receivables, drafts against Customers, and assignments of Receivables, upon and during the continuance of an Event of Default; (iii) to send verifications of Receivables to any Customer (provided, that, so long as no Event of Default has occurred and is continuing, Agent shall only conduct verifications of Receivables over the phone with participation from Borrowers or with Borrowers being present); (iv) to sign such Borrower’s name on any documents or instruments deemed necessary or appropriate by Agent to preserve, protect, or perfect Agent’s interest in the Collateral and to file same upon and during the continuance of an Event of Default; (v) to demand payment of the Receivables upon and during the continuance of an Event of Default; (vi) to enforce payment of the Receivables by legal proceedings or otherwise upon and during the continuance of an Event of Default; (vii) to exercise all of such Borrower’s rights and remedies with respect to the collection of the Receivables and any other Collateral upon and during the continuance of an Event of Default; (viii) to settle, adjust, compromise, extend or renew the Receivables upon and during the continuance of an Event of Default; (ix) to settle, adjust or compromise any legal proceedings brought to collect Receivables upon and during the continuance of an Event of Default; (x) to prepare, file and sign such Borrower’s name on a proof of claim in bankruptcy or similar document against any Customer upon and during the continuance of an Event of Default; (xi) to prepare, file and sign such Borrower’s name on any notice of Lien, assignment or satisfaction of Lien or similar document in connection with the Receivables upon and during the continuance of an Event of Default; (xii) to receive, open and dispose of all mail addressed to any Borrower to the extent such actions are taken in connection with operation and administration of Borrowers’ lockboxes or otherwise in connection with treasury management services; and (xiii) upon and during the continuance of an Event of Default, to do all other acts and things necessary to carry out this Agreement. All acts of said attorney or designee are hereby ratified and approved, and said attorney or designee shall not be liable for any acts of omission or commission nor for any error of judgment or mistake of fact or of law, unless constituting willful misconduct or gross negligence (as determined by a court of competent jurisdiction in a final non-appealable judgment); this power being coupled with an interest is irrevocable while any of the Obligations remain unpaid. Agent shall have the right at any time following the occurrence and during the continuation of an Event of Default, to change the address for delivery of mail addressed to any Borrower to such address as Agent may designate and to receive, open and dispose of all mail addressed to any Borrower.

(g) No Liability. Neither Agent nor any Lender shall, under any circumstances or in any event whatsoever, have any liability for any error or omission or delay of any kind occurring in the settlement, collection or payment of any of the Receivables or any instrument received in payment thereof, or for any damage resulting therefrom, except for the gross negligence or willful misconduct of the Agent as determined by a final and non-appealable judgment of a court of competent jurisdiction. Following the occurrence and during the continuance of an Event of Default, Agent may, without notice or consent from any Borrower, sue upon or otherwise collect, extend the time of payment of, compromise or settle for cash, credit or upon any terms any of the Receivables or any other securities, instruments or insurance applicable thereto and/or release any obligor thereof. Agent is authorized and empowered to accept, following the occurrence and during the continuance of an Event of Default, the return of the goods represented by any of the Receivables, without notice to or consent by any Borrower, all without discharging or in any way affecting any Borrower’s liability hereunder

(i) All proceeds of assets of the Borrowers and any other amounts payable to any Borrower at any time, shall be deposited by such Borrowers into either (A) during the period prior to the one hundred twentieth (120^th) day after the Closing Date, a collection account designated as such on Schedule 5.30 established at a bank reasonably satisfactory to Agent (each such bank, a “Blocked Account Bank”) pursuant to an arrangement with such Blocked Account Bank as may be selected by Borrowers and be acceptable to Agent or (B) a collection account established at PNC for the deposit of such proceeds (all such accounts in clauses (A) and (B), the “Collection Accounts”). Each Borrower shall deliver to Agent a Deposit Account Control Agreement, in form and substance satisfactory to Agent in its Permitted Discretion, with respect to each Collection Account other than any Excluded Deposit Account which shall be in “springing” form permitting Borrowers to access and use such Collection Accounts unless and until a “notice of sole control” (such notice, or any similar notice described in any applicable control agreement an “Activation Notice”) is issued by Agent to the bank at which such Collection Account is maintained; provided, that, Agent shall not issue such an Activation Notice except after the occurrence and during the continuance of a Trigger Event and shall revoke such Activation Notice if, subsequent thereto, the Trigger Period commenced by such Trigger Event shall have ended. Upon issuance of an Activation Notice, such Deposit Account Control Agreements shall provide that all available funds in each Collection Account will be transferred, on each Business Day, to Agent, either to any account maintained by Agent at such bank or by wire transfer to appropriate account(s) of Agent, and otherwise be in form and substance (including as to the extent of offset and statutory lien rights) reasonably satisfactory to Agent. All funds deposited in such Collection Accounts during the effectiveness of a Trigger Period shall immediately become the property of Agent and be applied to the outstanding Advances or Sand Tiger, as applicable. Neither Agent nor any Lender assumes any responsibility for such collection account arrangement, including any claim of accord and satisfaction or release with respect to deposits accepted by any bank maintaining a Collection Account.

(ii) Notwithstanding anything to the contrary herein or in any Other Document, Borrowers shall ensure that Agent does not receive, whether by deposit to the Collection Accounts or otherwise, any funds from any Customer located in a Sanctioned Country.

(iii) The parties hereto hereby acknowledge, confirm and agree that the implementation of the cash management arrangements contemplated herein is a contractual right provided to the Agent and the Lenders hereunder in order for the Agent and the Lenders to manage and monitor their collateral position and not a proceeding for enforcement or recovery of a claim, or pursuant to, or an enforcement of, any security or remedies whatsoever, the cash management arrangements contemplated herein are critical to the structure of the lending arrangements contemplated herein, the Agent and

Lenders are relying on the Credit Parties’ acknowledgement, confirmation and agreement with respect to such cash management arrangements in making accommodations of credit available to them and in particular that any accommodations of credit are being provided by the Agent and Lenders strictly on the basis of a borrowing base calculation to fully support and collateralize any such accommodations of credit hereunder.

(i) Adjustments. No Borrower will, without Agent’s consent, compromise or adjust any material amount of the Receivables (or extend the time for payment thereof) or accept any material returns of merchandise or grant any additional discounts, allowances or credits thereon except for those compromises, adjustments, returns, discounts, credits and allowances as have been granted in the ordinary course of business of such Borrower.

No Borrower shall open any new deposit account, securities account or investment account unless (i) Borrowers shall have given at least ten (10) days prior written notice to Agent and (ii) if such account is to be maintained with a bank, depository institution or securities intermediary that is not the Agent, such bank, depository institution or securities intermediary, each applicable Borrower and Agent shall first have entered into an account control agreement in form and substance satisfactory to Agent sufficient to give Agent “control” (for purposes of Articles 8 and 9 of the Uniform Commercial Code) over such account other than with respect to any Excluded Deposit Account.

The Equipment necessary to Borrowers’ business shall be maintained in good operating condition and repair (reasonable wear and tear and casualty excepted) and all necessary replacements of and repairs thereto shall be made so that the value and operating efficiency of the Equipment shall be maintained and preserved consistent with industry standards; provided that the same shall not be required if not necessary for the continued operation of the Borrowers’ business. No Borrower shall use or operate the Equipment in violation of any law, statute, ordinance, code, rule or regulation to the extent such use or operation could reasonably be expected to materially and adversely affect the operation of its business as currently conducted.

4.11. Exculpation of Liability. Nothing herein contained shall be construed to constitute Agent or any Lender as any Borrower’s agent for any purpose whatsoever, nor shall Agent or any Lender be responsible or liable for any shortage, discrepancy, damage, loss or destruction of any part of the Collateral wherever the same may be located and regardless of the cause thereof, except for the gross negligence or willful misconduct of the Agent as determined by a final and non-appealable judgment of a court of competent jurisdiction. Neither Agent nor any Lender, whether by anything herein or in any assignment or otherwise, assume any of any Borrower’s obligations under any contract or agreement assigned to Agent or such Lender, and neither Agent nor any Lender shall be responsible in any way for the performance by any Borrower of any of the terms and conditions thereof.

Credit Parties (or Borrowers if otherwise indicated) shall, and shall cause their Restricted Subsidiaries (or, if indicated, all of their Subsidiaries) to, until the Termination Date:

Comply in all material respects with all Applicable Laws with respect to the Collateral or any part thereof or to the operation of such Borrower’s business the non-compliance with which could reasonably be expected to have a Material Adverse Effect (except to the extent any separate provision of this Agreement shall expressly require compliance with any particular Applicable Law(s) pursuant to another standard). Each Borrower may, however, contest or dispute any Applicable Laws in any reasonable manner, provided that any related Lien is inchoate or stayed and sufficient reserves are established to the reasonable satisfaction of Agent to protect Agent’s Lien on or security interest in the Collateral.

6.2. Conduct of Business and Maintenance of Existence and Assets. (a) Conduct continuously and operate actively its business according to good business practices and maintain all of its properties useful or necessary in its business in good working order and condition (reasonable wear and tear excepted and except as may be disposed of in accordance with the terms of this Agreement), including all Intellectual Property necessary for the Borrowers’ business and take all actions necessary to enforce and protect the validity of any intellectual property right or other right included in the Collateral; (b) keep in full force and effect its existence and comply in all material respects with the laws and regulations governing the conduct of its business where the failure to do so could reasonably be expected to have a Material Adverse Effect; and (c) make all such reports and pay all such franchise and other taxes and license fees and do all such other acts and things as may be lawfully required to maintain its rights, licenses, leases, powers and franchises under the laws of the United States or any political subdivision thereof where the failure to do so could reasonably be expected to have a Material Adverse Effect.

Borrower’s including business interruption insurance; (ii) maintain a bond in such amounts as is customary in the case of companies engaged in businesses similar to such Borrower insuring against larceny, embezzlement or other criminal misappropriation of insured’s officers and employees who may either singly or jointly with others at any time have access to the assets or funds of such Borrower either directly or through authority to draw upon such funds or to direct generally the disposition of such assets; (iii) maintain public and product liability insurance against claims for personal injury, death or property damage suffered by others as is customary in the case of the Borrower’s properties or companies engaged in businesses similar to such Borrower’s; (iv) maintain all such worker’s compensation or similar insurance as may be required under the laws of any state or jurisdiction in which such Borrower is engaged in business; (v) furnish Agent with (A) copies of all policies and evidence of the maintenance of such policies by the renewal thereof at least thirty (30) days before any expiration date, and (B) appropriate loss payable endorsements in form and substance satisfactory to Agent, naming Agent as an additional insured and mortgagee and/or lender loss payee (as applicable) as its interests may appear with respect to all insurance coverage referred to in clauses (i), and (iii) above, and providing (I) that, during any Trigger Period, all proceeds thereunder shall be payable to Agent, (II) no such insurance shall be affected by any act or neglect of the insured or owner of the property described in such policy, and (III) that such policy and loss payable clauses may not be cancelled, amended or terminated unless at least thirty (30) days prior written notice is given to Agent (or in the case of non-payment, at least ten (10) days prior written notice). In the event of any loss thereunder, during any Trigger Period, the carriers named therein hereby are directed by Agent and the applicable Borrower to make payment for such loss to Agent and not to such Borrower and Agent jointly. If any insurance losses are paid by check, draft or other instrument payable to any Borrower and Agent jointly, Agent may endorse such Borrower’s name thereon and do such other things as Agent may deem advisable to reduce the same to cash.

(b) Each Borrower shall take all actions required under the Flood Laws and/or requested by Agent to assist in ensuring that each Lender is in compliance with the Flood Laws applicable to the Collateral, including, but not limited to, providing Agent with the address and/or GPS coordinates of each structure on any real property that will be subject to a mortgage in favor of Agent, for the benefit of Lenders, and, to the extent required, obtaining flood insurance for such property, structures and contents prior to such property, structures and contents becoming Collateral, and thereafter maintaining such flood insurance in full force and effect for so long as required by the Flood Laws.

During any Trigger Period, all loss recoveries shall be payable to Agent and all loss recoveries received by Agent under any such insurance may be applied to the Obligations, in such order as Agent in its sole discretion shall determine. Any surplus shall be paid by Agent to Borrowers or applied as may be otherwise required by law. During any Trigger Period, any deficiency thereon shall be paid by Borrowers to Agent, on demand. Anything hereinabove to the contrary notwithstanding, and subject to the fulfillment of the conditions set forth below, Agent shall remit to Borrowing Agent insurance proceeds received by Agent during any calendar year under insurance policies procured and maintained by Borrowers which insure Borrowers’ insurable properties to the extent such insurance proceeds do not exceed $10,000,000 in the aggregate during such calendar

year or $1,000,000 per occurrence. In the event the amount of insurance proceeds received by Agent for any occurrence exceeds $1,000,000, then Agent shall not be obligated to remit the insurance proceeds to Borrowing Agent unless Borrowing Agent shall provide Agent with evidence reasonably satisfactory to Agent that the insurance proceeds will be used by Borrowers to repair, replace or restore the insured property which was the subject of the insurable loss. In the event Borrowing Agent has previously received (or, after giving effect to any proposed remittance by Agent to Borrowing Agent would receive) insurance proceeds which equal or exceed $10,000,000 in the aggregate during any calendar year, then Agent may, in its sole discretion, either remit the insurance proceeds to Borrowing Agent upon Borrowing Agent providing Agent with evidence reasonably satisfactory to Agent that the insurance proceeds will be used by Borrowers to repair, replace or restore the insured property which was the subject of the insurable loss, or apply the proceeds to the Obligations, as aforesaid. The agreement of Agent to remit insurance proceeds in the manner above provided shall be subject in each instance to satisfaction of each of the following conditions: (x) No Event of Default or Default shall then have occurred and be continuing, (y) Borrowers shall use such insurance proceeds promptly to repair, replace or restore the insurable property which was the subject of the insurable loss and for no other purpose, and (z) such remittances shall be made under such procedures as Agent may establish. If any Borrower fails to obtain insurance as hereinabove provided, or to keep the same in force, Agent, if Agent so elects, may obtain such insurance and pay the premium therefor on behalf of such Borrower, which payments shall be charged to Borrowers’ Account or Sand Tiger’s Account, as applicable, and constitute part of the obligations.

6.7. Payment of Indebtedness and Leasehold Obligations. Pay, discharge or otherwise satisfy (i) at or before maturity (subject, where applicable, to specified grace periods) all its Indebtedness, except when the failure to do so could not reasonably be expected to have a Material Adverse Effect or when the amount or validity thereof is currently being Properly Contested, subject at all times to any applicable subordination arrangement in favor of Lenders and (ii) when due its rental obligations under all leases under which it is a tenant, and shall otherwise comply, in all material respects, with all other terms of such leases and keep them in full force and effect.

(a) Use commercially reasonable efforts to ensure that the Real Property and all operations and businesses conducted thereon are in material compliance and remain in material compliance with all Environmental Laws and it shall manage any and all Hazardous Substances on any Real Property in material compliance with Environmental Laws.

(b) Establish and maintain an environmental management and compliance system to assure and monitor continued compliance with all applicable Environmental Laws which system shall include periodic environmental compliance audits to be conducted by knowledgeable environmental professionals. All potential violations and violations of Environmental Laws shall be reviewed with legal counsel to determine any required reporting to applicable Governmental Bodies and any required corrective actions to address such potential violations or violations.

(c) Respond promptly to any Hazardous Discharge or Environmental Complaint known to a Borrower and take all necessary action in order to safeguard the health of any Person and to avoid subjecting a material portion of the Collateral or Real Property to any Lien. If any Borrower shall fail to respond promptly to any Hazardous Discharge or Environmental Complaint or any Borrower shall fail to comply with any of the requirements of any Environmental Laws, and such failure results in an Event of Default, Agent on behalf of Lenders may, but without the obligation to do so, for the sole purpose of protecting Agent’s interest in the Collateral: (i) give such notices or (ii) enter onto the Real Property (or authorize third parties to enter onto the Real Property) and take such actions as Agent (or such third parties as directed by Agent) deem reasonably necessary, to remediate, remove, mitigate or otherwise manage with any such Hazardous Discharge or Environmental Complaint. All reasonable out-of-pocket costs and expenses incurred by Agent and Lenders (or such third parties) in the exercise of any such rights, including any sums paid in connection with any judicial or administrative investigation or proceedings, fines and penalties, together with interest thereon from the date expended at the Default Rate for Domestic Rate Loans constituting Revolving Advances shall be paid upon demand by Borrowers (other than Sand Tiger) or Sand Tiger, as applicable, and until paid shall be added to and become a part of the Obligations secured by the Liens created by the terms of this Agreement or any other agreement between Agent, any Lender and any Borrower.

Upon the occurrence and during the continuation of any Event of Default, subject to Applicable Law, Agent shall have the right to exercise any and all rights and remedies provided for herein, under the Other Documents, under the Uniform Commercial Code, PPSA and at law or equity generally, including the right to foreclose the security interests granted herein and to realize upon any Collateral by any available judicial procedure and/or to take possession of and sell any or all of the Collateral with or without judicial process. Agent may enter any of any Borrower’s premises or other premises without legal process and without incurring liability to any Borrower therefor, and Agent may thereupon, or at any time thereafter, in its discretion without notice or demand, take the Collateral and remove the same to such place as Agent may deem advisable and Agent may require Borrowers to make the Collateral available to Agent at a convenient place. With or without having the Collateral at the time or place of sale, Agent may sell the Collateral, or any

part thereof, at public or private sale, at any time or place, in one or more sales, at such price or prices, and upon such terms, either for cash, credit or future delivery, as Agent may elect. Except as to that part of the Collateral which is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, Agent shall give Borrowers reasonable notification of such sale or sales, it being agreed that in all events written notice mailed to Borrowing Agent at least ten (10) days prior to such sale or sales is reasonable notification. At any public sale Agent or any Lender may bid for and become the purchaser, and Agent, any Lender or any other purchaser at any such sale thereafter shall hold the Collateral sold absolutely free from any claim or right of whatsoever kind, including any equity of redemption and all such claims, rights and equities are hereby expressly waived and released by each Borrower. In connection with the exercise of the foregoing remedies, including the sale of Inventory, Agent is granted a perpetual nonrevocable, royalty free, nonexclusive license and Agent is granted permission to use all of each Borrower’s (a) trademarks, trade styles, trade names, trade name applications, domain names, domain name applications, patents, patent applications, copyrights, service marks, licenses, franchises and other proprietary rights which are used or useful in connection with Inventory for the purpose of marketing, advertising for sale and selling or otherwise disposing of such Inventory and (b) Equipment for the purpose of completing the manufacture of unfinished goods. The cash proceeds realized from the sale of any Collateral shall be applied to the Obligations in the order set forth in Section 11.5 hereof unless required otherwise by Applicable Law. Noncash proceeds will only be applied to the Obligations as they are converted into cash. If any deficiency shall arise, Borrowers shall remain liable to Agent and Lenders therefor.

(b) To the extent that Applicable Law imposes duties on Agent to exercise remedies in a commercially reasonable manner, each Borrower acknowledges and agrees that it is not commercially unreasonable for Agent: (i) to fail to incur expenses reasonably deemed significant by Agent to prepare Collateral for disposition or otherwise to complete raw material or work in process into finished goods or other finished products for disposition; (ii) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of; (iii) to fail to exercise collection remedies against Customers or other Persons obligated on Collateral or to remove Liens on or any adverse claims against Collateral; (iv) to exercise collection remedies against Customers and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists; (v) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature; (vi) to contact other Persons, whether or not in the same business as any Borrower, for expressions of interest in acquiring all or any portion of such Collateral; (vii) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature; (viii) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets; (ix) to dispose of assets in wholesale rather than retail markets; (x) to disclaim disposition warranties, such as title, possession or quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure Agent against risks of loss, collection or disposition of Collateral or to provide to Agent a guaranteed return from the collection or disposition of Collateral; or (xii) to the extent deemed appropriate by the Agent, to obtain the

services of other brokers, investment bankers, consultants and other professionals to assist Agent in the collection or disposition of any of the Collateral. Each Borrower acknowledges that the purpose of this Section 11.1(b) is to provide non-exhaustive indications of what actions or omissions by Agent would not be commercially unreasonable in Agent’s exercise of remedies against the Collateral and that other actions or omissions by Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 11.1(b). Without limitation upon the foregoing, nothing contained in this Section 11.1(b) shall be construed to grant any rights to any Borrower or to impose any duties on Agent that would not have been granted or imposed by this Agreement or by Applicable Law in the absence of this Section 11.1(b).

(c) Upon the occurrence of an Event of Default which is continuing, Agent may seek the appointment of a receiver, receiver-manager, monitor or keeper (a “Receiver”) under the laws of Canada or any Province thereof including to take possession of all or any portion of the Collateral of Credit Parties or to operate same and, to the maximum extent permitted by law, may seek the appointment of such a receiver without the requirement of prior notice or a hearing. Any such Receiver shall, so far as concerns responsibility for his/her acts, be deemed agent of Credit Parties and not Agent and the Lenders, and Agent and the Lenders shall not be in any way responsible for any misconduct, negligence or non-feasance on the part of any such Receiver, his/her servants or employees. Subject to the provisions of the instrument appointing him/her, any such Receiver shall have power to take possession of Collateral of the Credit Parties, to preserve Collateral of the Credit Parties or its value, to carry on or concur in carrying on all or any part of the business of the Credit Parties and to sell, lease, license or otherwise dispose of or concur in selling, leasing, licensing or otherwise disposing of Collateral of the Credit Parties. To facilitate the foregoing powers, any such Receiver may, to the exclusion of all others, including the Credit Parties, enter upon, use and occupy all premises owned or occupied by the Credit Parties wherein Collateral of the Credit Parties may be situated, maintain Collateral of the Credit Parties upon such premises, borrow money on a secured or unsecured basis and use Collateral of the Credit Parties directly in carrying on the Credit Parties’ business or as security for loans or advances to enable the Receiver to carry on the Credit Parties’ business or otherwise, as such Receiver shall, in its discretion, determine. Except as may be otherwise directed by Agent, all money received from time to time by such Receiver in carrying out his/her appointment shall be received in trust for and paid over to Agent. Every such Receiver may, in the discretion of Agent, be vested with all or any of the rights and powers of Agent and the Lenders. Agent may, either directly or through its nominees, exercise any or all powers and rights given to a Receiver by virtue of the foregoing provisions of this paragraph.

11.2. Agent’s Discretion. Agent shall have the right in its sole discretion to determine which rights, Liens, security interests or remedies Agent may at any time pursue, relinquish, subordinate, or modify, which procedures, timing and methodologies to employ, and what any other action to take with respect to any or all of the Collateral and in what order, thereto and such determination will not in any way modify or affect any of Agent’s or Lenders’ rights hereunder as against Borrowers or each other.

(a) Subject to Section 14.13, in addition to any other rights which Agent or any Lender may have under Applicable Law, upon the occurrence and during the continuance of an Event of Default hereunder, Agent and such Lender shall have a right, immediately and without notice of any kind, to apply any Borrower’s or Sand Tiger’s (as applicable) property held by Agent and such Lender or any of their Affiliates to reduce the Obligations or Sand Tiger’s Obligations, in the case of Sand Tiger, and to exercise any and all rights of setoff which may be available to Agent and such Lender with respect to any deposits held by Agent or such Lender.

(b) If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of any of the Advances made by it resulting in such Lender’s receiving payment of a proportion of the aggregate amount of such Advances, greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Agent in writing of such fact, and (b) purchase (for cash at face value) a pro rata portion of the outstanding Advances (and participation interests in Letters of Credit) of each of the other Lenders (and such Lenders hereby agree to sell and to take all such further action to effectuate such sale) such that each Lender shall hold its pro rata share of the outstanding Advances (and participation interests) after giving effect to such purchase.

(c) Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against such Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

11.4. Rights and Remedies not Exclusive. The enumeration of the foregoing rights and remedies is not intended to be exhaustive and the exercise of any rights or remedy shall not preclude the exercise of any other right or remedies provided for herein or otherwise provided by law, all of which shall be cumulative and not alternative.

11.5. Allocation of Payments After Event of Default. Notwithstanding any other provisions of this Agreement to the contrary, after the occurrence and during the continuance of an Event of Default, all amounts collected or received by Agent on account of the Obligations (including without limitation any amounts on account of any of Cash Management Liabilities or Hedge Liabilities), or in respect of the Collateral may, at Agent’s discretion, be paid over or delivered as follows:

FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees) of Agent in connection with enforcing its rights and the rights of Lenders under this Agreement and the Other Documents, and any Out-of-Formula Loans and Protective Advances funded by Agent with respect to the Collateral under or pursuant to the terms of this Agreement;

THIRD, to the payment of all reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees) of each of the Lenders to the extent owing to such Lender pursuant to the terms of this Agreement;

FOURTH, to the payment of all of the Obligations consisting of accrued interest on account of the Swing Loans;

FIFTH, to the payment of the outstanding principal amount of the Obligations consisting of Swing Loans;

SIXTH, to the payment of all Obligations arising under this Agreement and the Other Documents consisting of accrued fees and interest (other than interest in respect of Swing Loans paid pursuant to clause FOURTH above);

SEVENTH, to the payment of the outstanding principal amount of the Obligations (other than principal in respect of Swing Loans paid pursuant to clause FIFTH above) arising under this Agreement (other than Cash Management Liabilities and Hedge Liabilities) (including the payment or cash collateralization of any outstanding Letters of Credit in accordance with Section 3.2(b) hereof).

EIGHTH, to all other Obligations arising under this Agreement (other than Cash Management Liabilities and Hedge Liabilities) which shall have become due and payable (hereunder, under the Other Documents or otherwise) and not repaid pursuant to clauses “FIRST” through “SEVENTH” above;

NINTH, to any Cash Management Liabilities and Hedge Liabilities which shall have become due and payable or otherwise and not repaid pursuant to Clauses “FIRST” through “EIGHTH” above; and

TENTH, to all other Obligations which shall have become due and payable and not repaid pursuant to clauses “FIRST” through “NINTH”; and

ELEVENTH, to the payment of the surplus, if any, to whoever may be lawfully entitled to receive such surplus.

In carrying out the foregoing, (i) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category; (ii) each of the Lenders shall receive (so long as it is not a Defaulting Lender) an amount equal to its pro rata share (based on the proportion that the then outstanding Advances held by such Lender bears to the aggregate then outstanding Advances) of amounts available to be applied pursuant to clauses “SIXTH”, “SEVENTH”, “EIGHTH” and “TENTH” above; and, with respect to clause “NINTH” above, an amount equal to its pro rata share (based on the proportion that the then outstanding Cash Management Liabilities and Hedge Liabilities held by such Lender bears to the aggregate then outstanding Cash Management Liabilities and Hedge Liabilities; and (iii) notwithstanding anything to the contrary in this Section 11.5, no Swap Obligations of any Non-Qualifying Party shall be paid with amounts received from such Non-Qualifying Party under its Guaranty (including sums received as a result of the exercise of remedies with respect to such Guaranty) or from the proceeds of such Non-Qualifying Party’s Collateral if such Swap Obligations would constitute Excluded Hedge Liabilities, provided, however, that to the extent possible appropriate adjustments shall be made with respect to payments and/or the proceeds of Collateral from other Borrowers and/or Guarantors that are Eligible Contract Participants with respect to such Swap

Obligations to preserve the allocation to Obligations otherwise set forth above in this Section 11.5; and (iv) to the extent that any amounts available for distribution pursuant to clause “SEVENTH” above are attributable to the issued but undrawn amount of outstanding Letters of Credit, such amounts shall be held by Agent as cash collateral for the Letters of Credit pursuant to Section 3.2(b) hereof and applied (A) first, to reimburse Issuer from time to time for any drawings under such Letters of Credit and (B) then, following the expiration of all Letters of Credit, to all other obligations of the types described in clauses “SEVENTH,” “EIGHTH”, “NINTH”, and “TENTH” above in the manner provided in this Section 11.5. Notwithstanding the foregoing, the assets of Sand Tiger shall only be applied to pay down Sand Tiger’s Obligations.

12.1. Waiver of Notice. To the fullest extent permitted by Applicable Law, each Borrower hereby waives notice of non-payment of any of the Receivables, demand, presentment, protest and notice thereof with respect to any and all instruments, notice of acceptance hereof, notice of loans or advances made, credit extended, Collateral received or delivered, or any other action taken in reliance hereon, and all other demands and notices of any description, except such as are expressly provided for herein.

12.2. Delay. No delay or omission on Agent’s or any Lender’s part in exercising any right, remedy or option shall operate as a waiver of such or any other right, remedy or option or of any Default or Event of Default.

12.3. Jury Waiver. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, COUNTERCLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A) ARISING UNDER THIS AGREEMENT, ANY OTHER DOCUMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR (B) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO THIS AGREEMENT, ANY OTHER DOCUMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE AND EACH PARTY HEREBY CONSENTS THAT ANY SUCH CLAIM, COUNTERCLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENTS OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

13.1. Term. This Agreement, which shall inure to the benefit of and shall be binding upon the respective successors and permitted assigns of each Borrower, Agent and each Lender, shall become effective on the date hereof and shall continue in full force and effect until

November 25, 2019 (the “Term”) unless sooner terminated as herein provided. Borrowers may terminate this Agreement at any time upon five (5) Business Days prior written notice to Agent upon payment in full of the Obligations (other than contingent indemnity claims not yet asserted or threatened). Each notice delivered by the Borrowing Agent under this Section 13.1 may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrowers (by notice to the Agent on or prior to the specified effective date) if such condition is not satisfied. In the event that the Maximum Revolving Advance Amount (whether voluntarily or involuntarily) is permanently reduced or terminated on or prior to the date immediately preceding the first anniversary of the Closing Date, Borrowers (other than Sand Tiger) shall concurrently pay to the Agent, for the benefit of Lenders on a pro rata basis, a termination or reduction fee in an amount equal to one percent (1%) of the amount that the Maximum Revolving Advance Amount is so reduced or terminated below $170,000,000.

13.2. Termination. The termination of the Agreement shall not affect Agent’s or any Lender’s rights, or any of the Obligations having their inception prior to the effective date of such termination or any Obligations which pursuant to the terms hereof continue to accrue after such date, and the provisions hereof shall continue to be fully operative until all transactions entered into, rights or interests created and Obligations have been fully and indefeasibly paid, disposed of, concluded or liquidated. The security interests, Liens and rights granted to Agent and Lenders hereunder and the financing statements filed hereunder shall continue in full force and effect, notwithstanding the termination of this Agreement or the fact that Borrowers’ Accounts may from time to time be temporarily in a zero or credit position, until all of the Obligations of each Borrower have been indefeasibly paid and performed in full after the termination of this Agreement or each Borrower has furnished Agent and Lenders with an indemnification satisfactory to Agent and Lenders with respect thereto. Accordingly, each Borrower waives any rights which it may have under the Uniform Commercial Code or PPSA to demand the filing of termination statements with respect to the Collateral, and Agent shall not be required to send such termination statements to each Borrower, or to file them with any filing office, unless and until this Agreement shall have been terminated in accordance with its terms and all Obligations have been indefeasibly paid in full in immediately available funds. All representations, warranties, covenants, waivers and agreements contained herein shall survive termination hereof until all Obligations are indefeasibly paid and performed in full.

14.1. Appointment. Each Lender hereby designates PNC to act as Agent for such Lender under this Agreement and the Other Documents. Each Lender hereby irrevocably authorizes Agent to take such action on its behalf under the provisions of this Agreement and the Other Documents and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of Agent by the terms hereof and thereof and such other powers as are reasonably incidental thereto and Agent shall hold all Collateral, payments of principal and interest, fees (except the fees set forth in Sections 2.8(b) and the Fee Letter), charges and collections received pursuant to this Agreement, for the ratable benefit of Lenders. Agent may perform any of its duties hereunder by or through its agents or employees. As to any matters not expressly provided for by this Agreement (including collection of the Note) Agent shall not be required to exercise any discretion or take any action, but shall be

required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of Required Lenders, and such instructions shall be binding; provided, however, that Agent shall not be required to take any action which, in Agent’s discretion, exposes Agent to liability or which is contrary to this Agreement or the Other Documents or Applicable Law unless Agent is furnished with an indemnification reasonably satisfactory to Agent with respect thereto.

14.2. Nature of Duties. Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the Other Documents. Neither Agent nor any of its officers, directors, employees or agents shall be (i) liable for any action taken or omitted by them as such hereunder or in connection herewith, unless caused by their gross (not mere) negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment), or (ii) responsible in any manner for any recitals, statements, representations or warranties made by any Borrower or any officer thereof contained in this Agreement, or in any of the Other Documents or in any certificate, report, statement or other document referred to or provided for in, or received by Agent under or in connection with, this Agreement or any of the Other Documents or for the value, validity, effectiveness, genuineness, due execution, enforceability or sufficiency of this Agreement, or any of the Other Documents or for any failure of any Borrower to perform its obligations hereunder or under any Other Document. Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any of the Other Documents, or to inspect the properties, books or records of any Borrower. The duties of Agent as respects the Advances to Borrowers shall be mechanical and administrative in nature; Agent shall not have by reason of this Agreement a fiduciary relationship in respect of any Lender; and nothing in this Agreement, expressed or implied, is intended to or shall be so construed as to impose upon Agent any obligations in respect of this Agreement or the transactions described herein except as expressly set forth herein.

Without limiting the foregoing, the Agent shall not be required to act hereunder or to advance its own funds or otherwise incur any financial liability in the performance of its duties or the exercise of its rights hereunder and under any Other Document, and shall in all cases be fully justified in failing or refusing to act hereunder unless it shall receive further assurances to its satisfaction from the Lenders of their indemnification obligations under and in accordance with the provisions of Section 14.7 against any and all liability and expense that may be incurred by it by reason of taking or continuing to take or refraining from taking any such action. The Agent shall be fully justified in requesting direction from the Required Lenders in the event this Agreement or any Other Document is silent or vague with respect to Agent’s duties, rights or obligations. The Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders or (ii) in the absence of its own gross negligence or willful misconduct, as determined by a court of competent jurisdiction in a final and non-appealable decision. In no instance shall the Agent have any liability for special, consequential or indirect damages or penalties (including lost profits) even if it has been advised of the likelihood of the same. Without prejudice to the generality of the foregoing, the Agent shall not be liable for any damage or loss resulting from or caused by events or circumstances beyond the Agent’s reasonable control, including nationalization, expropriation, currency restrictions, the interruption, disruption or suspension of the normal procedures and practices of

any securities market, power, mechanical, communications or other technological failures or interruptions, computer viruses or the like, acts of war or terrorism, riots, revolution, acts of God, work stoppages, strikes, national disasters of any kind, or other similar events or acts.

14.3. Lack of Reliance on Agent. Independently and without reliance upon Agent or any other Lender, each Lender has made and shall continue to make (i) its own independent investigation of the financial condition and affairs of each Credit Party in connection with the making and the continuance of the Advances hereunder and the taking or not taking of any action in connection herewith, and (ii) its own appraisal of the creditworthiness of each Credit Party. Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before making of the Advances or at any time or times thereafter except as shall be provided by any Credit Party pursuant to the terms hereof. Agent shall not be responsible to any Lender for any recitals, statements, information, representations or warranties herein or in any agreement, document, certificate or a statement delivered in connection with or for the execution, effectiveness, genuineness, validity, enforceability, collectability, sufficiency or value of this Agreement or any Other Document or any other instrument or document furnished pursuant hereto or thereto, or of the financial condition of any Credit Party, or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement, the Note, the Other Documents or the financial condition of any Borrower, or the existence of any Event of Default or any Default.

14.4. Resignation of Agent; Successor Agent. Agent may resign on sixty (60) days written notice to each Lender and Borrowing Agent and upon such resignation, Required Lenders will promptly designate a successor Agent reasonably satisfactory to Borrowers (provided that no such approval by Borrowers shall be required (i) in any case where the successor Agent is one of the Lenders or (ii) after the occurrence and during the continuance of any Event of Default). Any such successor Agent shall succeed to the rights, powers and duties of Agent, and shall in particular succeed to all of Agent’s right, title and interest in and to all of the Liens in the Collateral securing the Obligations created hereunder or any Other Document (including the Pledge Agreement and all account control agreements), and the term “Agent” shall mean such successor agent effective upon its appointment, and the former Agent’s rights, powers and duties as Agent shall be terminated, without any other or further act or deed on the part of such former Agent. However, notwithstanding the foregoing, if at the time of the effectiveness of the new Agent’s appointment, any further actions need to be taken in order to provide for the legally binding and valid transfer of any Liens in the Collateral from former Agent to new Agent and/or for the perfection of any Liens in the Collateral as held by new Agent or it is otherwise not then possible for new Agent to become the holder of a fully valid, enforceable and perfected Lien as to any of the Collateral, former Agent shall continue to hold such Liens solely as agent for perfection of such Liens on behalf of new Agent until such time as new Agent can obtain a fully valid, enforceable and perfected Lien on all Collateral, provided that Agent shall not be required to or have any liability or responsibility to take any further actions after such date as such agent for perfection to continue the perfection of any such Liens (other than to forego from taking any affirmative action to release any such Liens). After any Agent’s resignation as Agent, the provisions of this Article XIV, and any indemnification rights under this Agreement, including without limitation, rights arising under Section 16.5 hereof, shall inure to its benefit as

to any actions taken or omitted to be taken by it while it was Agent under this Agreement (and in the event resigning Agent continues to hold any Liens pursuant to the provisions of the immediately preceding sentence, the provisions of this Article XIV and any indemnification rights under this Agreement, including without limitation, rights arising under Section 16.5 hereof, shall inure to its benefit as to any actions taken or omitted to be taken by it in connection with such Liens).

14.5. Certain Rights of Agent. If Agent shall request instructions from Lenders with respect to any act or action (including failure to act) in connection with this Agreement or any Other Document, Agent shall be entitled to refrain from such act or taking such action unless and until Agent shall have received instructions from Required Lenders; and Agent shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, Lenders shall not have any right of action whatsoever against Agent as a result of its acting or refraining from acting hereunder in accordance with the instructions of Required Lenders.

14.6. Reliance. Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, order or other document or telephone message believed by it to be genuine and correct and to have been signed, sent or made by the proper person or entity, and, with respect to all legal matters pertaining to this Agreement and the Other Documents and its duties hereunder, upon advice of counsel selected by it. Agent may employ agents and attorneys-in-fact and shall not be liable for the acts, omissions, negligence or misconduct of any such agents or attorneys-in-fact selected by Agent with reasonable care. In determining compliance with any condition hereunder, the Agent shall be entitled to receive, and shall not incur any liability for relying upon, a certificate of an Authorized Officer or an opinion of counsel or both certifying as to compliance with such condition. The Agent may consult with legal counsel (who may be counsel for the Credit Parties or any Lender), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

14.7. Notice of Default. Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder or under the Other Documents, unless Agent has received notice from a Lender or Borrowing Agent referring to this Agreement or the Other Documents, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that Agent receives such a notice, Agent shall give notice thereof to Lenders. Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by Required Lenders; provided, that, unless and until Agent shall have received such directions, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of Lenders.

14.8. Indemnification. To the extent Agent is not reimbursed and indemnified by Borrowers, each Lender will reimburse and indemnify Agent in proportion to its respective portion of the outstanding Advances and its respective Participation Commitments in the outstanding Letters of Credit and outstanding Swing Loans (or, if no Advances are outstanding, pro rata according to the percentage that its Commitment Amount constitutes of the total aggregate Commitment Amounts), from and against any and all liabilities, obligations, losses,

damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against Agent in performing its duties hereunder, or in any way relating to or arising out of this Agreement or any Other Document; provided that Lenders shall not be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Agent’s gross (not mere) negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment).

14.9. Agent in its Individual Capacity. With respect to the obligation of Agent to lend under this Agreement, the Advances made by it shall have the same rights and powers hereunder as any other Lender and as if it were not performing the duties as Agent specified herein; and the term “Lender” or any similar term shall, unless the context clearly otherwise indicates, include Agent in its individual capacity as a Lender. Agent may engage in business with any Borrower as if it were not performing the duties specified herein, and may accept fees and other consideration from any Borrower for services in connection with this Agreement or otherwise without having to account for the same to Lenders.

14.10. Delivery of Documents. To the extent Agent receives financial statements required under Sections 9.7, 9.8, 9.9, 9.12 and 9.13 or Borrowing Base Certificates from any Borrower pursuant to the terms of this Agreement which any Borrower is not obligated to deliver to each Lender, Agent will promptly furnish such documents and information to Lenders.

14.11. Borrowers’ Undertaking to Agent. Without prejudice to their respective obligations to Lenders under the other provisions of this Agreement, each Borrower hereby undertakes with Agent to pay to Agent from time to time on demand all amounts from time to time due and payable by it for the account of Agent or Lenders or any of them pursuant to this Agreement to the extent not already paid. Any payment made pursuant to any such demand shall pro tanto satisfy the relevant Borrower’s obligations to make payments for the account of Lenders or the relevant one or more of them pursuant to this Agreement.

14.12. No Reliance on Agent’s Customer Identification Program. To the extent the Advances or this Agreement is, or becomes, syndicated in cooperation with other Lenders, each Lender acknowledges and agrees that neither such Lender, nor any of its Affiliates, participants or assignees, may rely on Agent to carry out such Lender’s, Affiliate’s, participant’s or assignee’s customer identification program, or other obligations required or imposed under or pursuant to the USA PATRIOT Act or the regulations thereunder, including the regulations contained in 31 CFR 103.121 (as hereafter amended or replaced, the “CIP Regulations”), or any other Anti-Terrorism Law, including any programs involving any of the following items relating to or in connection with any of Borrowers, their Affiliates or their agents, the Other Documents or the transactions hereunder or contemplated hereby: (i) any identity verification procedures, (ii) any recordkeeping, (iii) comparisons with government lists, (iv) customer notices or (v) other procedures required under the CIP Regulations or such Anti-Terrorism Laws.

14.13. Other Agreements. Each of the Lenders agrees that it shall not, without the express consent of Agent, and that it shall, to the extent it is lawfully entitled to do so, upon the request of Agent, set off against the Obligations, any amounts owing by such Lender to any Borrower or any deposit accounts of any Borrower now or hereafter maintained with such

Lender. Anything in this Agreement to the contrary notwithstanding, each of the Lenders further agrees that it shall not, unless specifically requested to do so by Agent, take any action to protect or enforce its rights arising out of this Agreement or the Other Documents, it being the intent of Lenders that any such action to protect or enforce rights under this Agreement and the Other Documents shall be taken in concert and at the direction or with the consent of Agent or Required Lenders.

(a) Each Borrower hereby irrevocably designates Borrowing Agent to be its attorney and agent and in such capacity to (i) borrow, (ii) request advances, (iii) request the issuance of Letters of Credit, (iv) sign and endorse notes, (v) execute and deliver all instruments, documents, applications, security agreements, reimbursement agreements and letter of credit agreements for Letters of Credit and all other certificates, notice, writings and further assurances now or hereafter required hereunder, (vi) make elections regarding interest rates, (vii) give instructions regarding Letters of Credit and agree with Issuer upon any amendment, extension or renewal of any Letter of Credit and (viii) otherwise take action under and in connection with this Agreement and the Other Documents, all on behalf of and in the name such Borrower or Borrowers, and hereby authorizes Agent to pay over or credit all loan proceeds hereunder in accordance with the request of Borrowing Agent.

(b) The handling of this credit facility as a co-borrowing facility with a borrowing agent in the manner set forth in this Agreement is solely as an accommodation to Borrowers and at their request. Neither Agent nor any Lender shall incur liability to Borrowers as a result thereof. To induce Agent and Lenders to do so and in consideration thereof, each Borrower hereby indemnifies Agent and each Lender and holds Agent and each Lender harmless from and against any and all liabilities, expenses, losses, damages and claims of damage or injury asserted against Agent or any Lender by any Person arising from or incurred by reason of the handling of the financing arrangements of Borrowers as provided herein, reliance by Agent or any Lender on any request or instruction from Borrowing Agent or any other action taken by Agent or any Lender with respect to this Section 15.1 except due to willful misconduct or gross (not mere) negligence by the indemnified party (as determined by a court of competent jurisdiction in a final and non-appealable judgment), and except that, Sand Tiger shall only be liable for the Sand Tiger Obligations.

(c) All Obligations shall be joint and several (provided, Sand Tiger shall only be liable for the Sand Tiger Obligations), and each Borrower shall make payment upon the maturity of the Obligations by acceleration or otherwise, and such obligation and liability on the part of each Borrower shall in no way be affected by any extensions, renewals and forbearance granted by Agent or any Lender to any Borrower, failure of Agent or any Lender to give any Borrower notice of borrowing or any other notice, any failure of Agent or any Lender to pursue or preserve its rights against any Borrower, the release by Agent or any Lender of any Collateral now or thereafter acquired from any Borrower, and such agreement by each Borrower to pay upon any notice issued pursuant thereto is unconditional and unaffected by prior recourse by Agent or any Lender to the other Borrowers or any Collateral for such Borrower’s Obligations or the lack thereof. Each Borrower waives all suretyship defenses.

15.2. Waiver of Subrogation. Each Borrower expressly waives any and all rights of subrogation, reimbursement, indemnity, exoneration, contribution of any other claim which such Borrower may now or hereafter have against any other Borrower or any other Person directly or contingently liable for the Obligations hereunder, or against or with respect to any other Borrowers’ property (including, without limitation, any property which is Collateral for the Obligations), arising from the existence or performance of this Agreement, until termination of this Agreement and repayment in full of the Obligations (other than contingent indemnification obligations in respect of which no assertion of liability has been made).

15.3. Common Enterprise. The successful operation and condition of each of the Borrowers (other than Sand Tiger) is dependent on the continued successful performance of the functions of the group of Borrowers as a whole and the successful operation of each Borrower is dependent on the successful performance and operation of each other Borrower. Each of the Borrowers expects to derive benefit (and its board of directors or other governing body has determined that it may reasonably be expected to derive benefit), directly and indirectly, from successful operations of Holdings and each of the other Borrowers. Each Borrower expects to derive benefit (and the boards of directors or other governing body of each such Borrower have determined that it may reasonably be expected to derive benefit), directly and indirectly, from the credit extended by the Lenders to the Borrowers hereunder, both in their separate capacities and as members of the group of companies. Each Borrower has determined that execution, delivery, and performance of this Agreement and any Other Documents to be executed by such Borrower is within its corporate purpose, will be of direct and indirect benefit to such Borrower, and is in its best interest.

16.1. Governing Law. This Agreement and each Other Document (unless and except to the extent expressly provided otherwise in any such Other Document), and all matters relating hereto or thereto or arising herefrom or therefrom (whether arising under contract law, tort law or otherwise) shall, in accordance with Section 5-1401 of the General Obligations Law of the State of New York, be governed by and construed in accordance with the laws of the State of New York applied to contracts to be performed wholly within the State of New York. Any judicial proceeding brought by or against any Borrower with respect to any of the Obligations, this Agreement, the Other Documents or any related agreement may be brought in any court of competent jurisdiction in the State of New York, United States of America, and, by execution and delivery of this Agreement, each Borrower accepts for itself and in connection with its properties, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts, and irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement, but with respect to Sand Tiger only, the Agent and Lenders shall not be precluded from initiating any proceeding against it in the courts of the Province of Alberta, Canada in their sole discretion. Each Borrower hereby waives personal service of any and all process upon it and consents that all such service of process may be made by certified or registered mail (return receipt requested) directed to Borrowing Agent at its address set forth in Section 16.6 and service so made shall be deemed completed five (5) days after the same shall have been so deposited in

the mails of the United States of America, or, at Agent’s option, by service upon Borrowing Agent which each Borrower irrevocably appoints as such Borrower’s Agent for the purpose of accepting service within the State of New York. Nothing herein shall affect the right to serve process in any manner permitted by law or shall limit the right of Agent or any Lender to bring proceedings against any Borrower in the courts of any other jurisdiction. Each Borrower waives any objection to jurisdiction and venue of any action instituted hereunder and shall not assert any defense based on lack of jurisdiction or venue or based upon forum non conveniens. Each Borrower waives the right to remove any judicial proceeding brought against such Borrower in any state court to any federal court. Any judicial proceeding by any Borrower against Agent or any Lender involving, directly or indirectly, any matter or claim in any way arising out of, related to or connected with this Agreement or any related agreement, shall be brought only in a federal or state court located in the County of New York, State of New York (or, with respect to Sand Tiger) the Province of Alberta.

(a) THIS AGREEMENT AND THE DOCUMENTS EXECUTED CONCURRENTLY HEREWITH CONTAIN THE ENTIRE UNDERSTANDING BETWEEN EACH BORROWER, AGENT AND EACH LENDER AND SUPERSEDES ALL PRIOR AGREEMENTS AND UNDERSTANDINGS, IF ANY, RELATING TO THE SUBJECT MATTER HEREOF. ANY PROMISES, REPRESENTATIONS, WARRANTIES OR GUARANTEES NOT HEREIN CONTAINED AND HEREINAFTER MADE SHALL HAVE NO FORCE AND EFFECT UNLESS IN WRITING, SIGNED BY EACH BORROWER’S, AGENT’S AND EACH LENDER’S RESPECTIVE OFFICERS. Neither this Agreement nor any portion or provisions hereof may be changed, modified, amended, waived, supplemented, discharged, cancelled or terminated orally or by any course of dealing, or in any manner other than by an agreement in writing, signed by the party to be charged. Notwithstanding the foregoing, Agent may modify this Agreement or any of the Other Documents for the purposes of completing missing content or correcting erroneous content of an administrative nature, without the need for a written amendment, provided that the Agent shall send a copy of any such modification to the Borrowers and each Lender (which copy may be provided by electronic mail). Each Borrower acknowledges that it has been advised by counsel in connection with the execution of this Agreement and Other Documents and is not relying upon oral representations or statements inconsistent with the terms and provisions of this Agreement.

(b) Required Lenders, Agent with the consent in writing of Required Lenders, and Borrowers may, subject to the provisions of this Section 16.2(b), from time to time enter into written supplemental agreements to this Agreement or the Other Documents (other than with respect to Cash Management Products and Services and Lender-Provided Hedges, other similar agreements or the Fee Letter, which shall require only the consent of the parties thereto) executed by the applicable Credit Parties, for the purpose of adding or deleting any provisions or otherwise changing, varying or waiving in any manner the rights of Lenders, Agent or Borrowers thereunder or the conditions, provisions or terms thereof or waiving any Event of Default thereunder, but only to the extent specified in such written agreements; provided, however, that no such supplemental agreement shall:

(ix) increase the Advance Rates above the Advance Rates in effect on the Closing Date without the consent of Supermajority Lenders;

(x) modify the definitions of Eligible Receivables, Eligible Equipment, Eligible Inventory, Eligible In-Transit Inventory, Eligible Unbilled Receivables, Eligible Equipment Sublimit, Letter of Credit Sublimit or the Maximum Swing Loan Advance Amount in effect on the Closing Date without the consent of Supermajority Lenders;

(xii) increase the amount of proceeds of direct Revolving Advances that may be made available, and remain outstanding on any day, to Sand Tiger without the consent of each Lender directly affected thereby.

(c) Any such supplemental agreement shall apply equally to each Lender and shall be binding upon Borrowers, Lenders and Agent and all future holders of the Obligations. In the case of any waiver, Borrowers, Agent and Lenders shall be restored to their former positions and rights, and any Event of Default waived shall be deemed to be cured and not continuing, but no waiver of a specific Event of Default shall extend to any subsequent Event of Default (whether or not the subsequent Event of Default is the same as the Event of Default which was waived), or impair any right consequent thereon.

(d) In the event that Agent requests the consent of a Lender pursuant to this Section 16.2 and such consent is denied, then Agent may, at its option, require such Lender to assign its interest in the Advances to Agent or to another Lender or to any other Person designated by Agent (the “Designated Lender”), for a price equal to (i) the then outstanding principal amount thereof plus (ii) accrued and unpaid interest and fees due such Lender, which interest and fees shall be paid when collected from Borrowers. In the event Agent elects to require any Lender to assign its interest to Agent or to the Designated Lender, Agent will so notify such Lender in writing within forty five (45) days following such Lender’s denial, and such Lender will assign its interest to Agent or the Designated Lender no later than five (5) days following receipt of such notice pursuant to a Commitment Transfer Supplement executed by such Lender, Agent or the Designated Lender, as appropriate, and Agent.

(e) Notwithstanding (i) the existence of a Default or an Event of Default, (ii) that any of the other applicable conditions precedent set forth in Section 8.2 hereof have not been satisfied or (iii) any other provision of this Agreement, Agent may at its discretion and without the consent of the Required Lenders, voluntarily permit the outstanding Revolving Advances at any time to exceed the Formula Amount by up to ten percent (10%) of the Formula Amount for up to thirty (30) consecutive Business Days (the “Out-of-Formula Loans”); provided, that, such outstanding Advances do not exceed the Maximum Revolving Advance Amount. If Agent is willing in its sole and absolute discretion to make such Out-of-Formula Loans, Lenders holding the Commitments shall be obligated to fund such Out-of-Formula Loans in accordance with their respective Commitment Percentages, and such Out-of-Formula Loans shall be payable on demand and shall bear interest at the Default Rate for Revolving Advances consisting of Domestic Rate Loans; provided that, if Agent does permit Out-of-Formula Loans, neither Agent nor Lenders shall be deemed thereby to have changed the limits of Section 2.1(a) nor shall any Lender be obligated to fund Revolving Advances in excess of its Commitment Amount. For purposes of this paragraph, the discretion granted to Agent hereunder shall not preclude involuntary overadvances that may result from time to time due to the fact that the Formula Amount was unintentionally exceeded for any reason, including, but not limited to, Collateral previously deemed to be either “Eligible Receivables”, “Eligible Equipment”, “Eligible Inventory”, “Eligible In-Transit Inventory” or “Eligible Unbilled Receivables”, as applicable, becomes ineligible, collections of Receivables applied to reduce outstanding Revolving

Advances are thereafter returned for insufficient funds or overadvances are made to protect or preserve the Collateral. In the event Agent involuntarily permits the outstanding Revolving Advances to exceed the Formula Amount by more than ten percent (10%), Agent shall use its efforts to have Borrowers decrease such excess in as expeditious a manner as is practicable under the circumstances and not inconsistent with the reason for such excess. Revolving Advances made after Agent has determined the existence of involuntary overadvances shall be deemed to be involuntary overadvances and shall be decreased in accordance with the preceding sentence. To the extent any Out-of-Formula Loans are not actually funded by the other Lenders as provided for in this Section 16.2(e), Agent may elect in its discretion to fund such Out-of-Formula Loans and any such Out-of-Formula Loans so funded by Agent shall be deemed to be Revolving Advances made by and owing to Agent, and Agent shall be entitled to all rights (including accrual of interest) and remedies of a Lender holding a Commitment under this Agreement and the Other Documents with respect to such Revolving Advances.

(f) In addition to (and not in substitution of) the discretionary Revolving Advances permitted above in Section 16.2, the Agent is hereby authorized by Borrowers and the Lenders, at any time in the Agent’s sole discretion, regardless of (i) the existence of a Default or an Event of Default, (ii) whether any of the other applicable conditions precedent set forth in Section 8.2 hereof have not been satisfied or the commitments of Lenders to make Revolving Advances hereunder have been terminated for any reason, or (iii) any other contrary provision of this Agreement, to make Revolving Advances (“Protective Advances”) to Borrowers, subject to Section 2.1(a), on behalf of the Lenders which Agent, in its reasonable business judgment, deems necessary or desirable (a) to preserve or protect the Collateral, or any portion thereof, (b) to enhance the likelihood of, or maximize the amount of, repayment of the Advances and other Obligations, or (c) to pay any other amount chargeable to Borrowers pursuant to the terms of this Agreement; provided, that the Protective Advances made hereunder shall not exceed, in the aggregate, 10% of the Maximum Revolving Advance Amount; and provided further that at any time after giving effect to any such Protective Advances, the outstanding Revolving Advances, Swing Loans Maximum Undrawn Amount of all outstanding Letters of Credit do not exceed the Maximum Revolving Advance Amount. The Lenders holding the Commitments shall be obligated to fund such Protective Advances and effect a settlement with Agent therefore upon demand of Agent in accordance with their respective Commitment Percentages. To the extent any Protective Advances are not actually funded by the other Lenders as provided for in this Section 16.2(f), any such Protective Advances funded by Agent shall be deemed to be Revolving Advances made by and owing to Agent, and Agent shall be entitled to all rights (including accrual of interest) and remedies of a Lender holding a Commitment under this Agreement and the Other Documents with respect to such Revolving Advances.

(a) This Agreement shall be binding upon and inure to the benefit of each Borrower, Agent, each Lender, all future holders of the Obligations and their respective successors and permitted assigns, except that Borrowers may not assign or transfer any of their rights or obligations under this Agreement without the prior written consent of Agent and each Lender.

(b) Each Borrower acknowledges that in the regular course of commercial banking business one or more Lenders may at any time and from time to time sell participating interests in the Advances (other than Swing Loans) to other financial institutions (each such transferee or purchaser of a participating interest, a “Participant”). Each Participant may exercise all rights of payment (including rights of set-off to the extent permitted by Applicable Law) with respect to the portion of such Advances (other than Swing Loans) held by it or other Obligations payable hereunder as fully as if such Participant were the direct holder thereof provided that Borrowers shall not be required to pay to any Participant more than the amount which it would have been required to pay to Lender which granted an interest in its Advances or other Obligations payable hereunder to such Participant had such Lender retained such interest in the Advances hereunder or other Obligations payable hereunder and in no event shall Borrowers be required to pay any such amount arising from the same circumstances and with respect to the same Advances or other Obligations payable hereunder to both such Lender and such Participant. Each Participant shall have the benefits of Section 3.10 hereof to the extent it complies with the provisions thereof. Each Borrower hereby grants to any Participant a continuing security interest in any deposits, moneys or other property actually or constructively held by such Participant as security for the Participant’s interest in the Advances. No Lenders shall transfer, grant or sell any participation under which the participant shall have the right to approve any amendment or waiver of this Agreement except to the extent such amendment or waiver would require the approval of all Lenders pursuant to Section 16.2(b). Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Advances or other obligations under this Agreement and the Other Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under this Agreement or any Other Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Agent (in its capacity as Agent) shall have no responsibility for maintaining a Participant Register.

(c) Any Lender, with the consent of Agent and so long as no Event of Default then exists, Borrowing Agent (other than with respect to any sale, assignment or transfer from any Lender to any Affiliate of such Lender or to any other Lender or any other Lender’s Affiliates), which shall not be unreasonably withheld, conditioned or delayed, may sell, assign or transfer all or any part of its rights and obligations under or relating to Revolving Advances (other than Swing Loans) under this Agreement and the Other Documents to one or more additional banks or financial institutions and one or more additional banks or financial institutions may commit to make Advances hereunder (each a “Purchasing Lender”), in minimum amounts of not less than $5,000,000, pursuant to a Commitment Transfer Supplement, executed by a Purchasing Lender, the transferor Lender, and Agent and delivered to Agent for recording. Upon such execution, delivery, acceptance and recording, from and after the transfer

effective date determined pursuant to such Commitment Transfer Supplement, (i) Purchasing Lender thereunder shall be a party hereto and, to the extent provided in such Commitment Transfer Supplement, have the rights and obligations of a Lender thereunder with a Commitment Percentage as set forth therein, and (ii) the transferor Lender thereunder shall, to the extent provided in such Commitment Transfer Supplement, be released from its obligations under this Agreement, the Commitment Transfer Supplement creating a novation for that purpose. Such Commitment Transfer Supplement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing Lender and the resulting adjustment of the Commitment Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. Each Borrower hereby consents to the addition of such Purchasing Lender and the resulting adjustment of the Commitment Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. Borrowers shall execute and deliver such further documents and do such further acts and things in order to effectuate the foregoing.

(d) Any Lender, with the consent of Agent which shall not be unreasonably withheld or delayed, may directly or indirectly sell, assign or transfer all or any portion of its rights and obligations under or relating to Revolving Advances under this Agreement and the Other Documents to an entity, whether a corporation, partnership, trust, limited liability company or other entity that (i) is engaged in making, purchasing, holding or otherwise investing in bank loans and similar extensions of credit in the ordinary course of its business and (ii) is administered, serviced or managed by the assigning Lender or an Affiliate of such Lender (a “Purchasing CLO” and together with each Participant and Purchasing Lender, each a “Transferee” and collectively the “Transferees”), pursuant to a Commitment Transfer Supplement modified as appropriate to reflect the interest being assigned (“Modified Commitment Transfer Supplement”), executed by any intermediate purchaser, the Purchasing CLO, the transferor Lender, and Agent as appropriate and delivered to Agent for recording. Upon such execution and delivery, from and after the transfer effective date determined pursuant to such Modified Commitment Transfer Supplement, (i) Purchasing CLO thereunder shall be a party hereto and, to the extent provided in such Modified Commitment Transfer Supplement, have the rights and obligations of a Lender thereunder and (ii) the transferor Lender thereunder shall, to the extent provided in such Modified Commitment Transfer Supplement, be released from its obligations under this Agreement, the Modified Commitment Transfer Supplement creating a novation for that purpose. Such Modified Commitment Transfer Supplement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing CLO. Each Borrower hereby consents to the addition of such Purchasing CLO. Borrowers shall execute and deliver such further documents and do such further acts and things in order to effectuate the foregoing.

(e) Agent shall maintain at its address a copy of each Commitment Transfer Supplement and Modified Commitment Transfer Supplement delivered to it and a register (the “Register”) for the recordation of the names and addresses of each Lender and the outstanding principal, accrued and unpaid interest and other fees due hereunder. The entries in the Register shall be conclusive, in the absence of manifest error, and each Borrower, Agent and Lenders may

treat each Person whose name is recorded in the Register as the owner of the Advance recorded therein for the purposes of this Agreement. The Register shall be available for inspection by any Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice. Agent shall receive a fee in the amount of $3,500 payable by the applicable Purchasing Lender and/or Purchasing CLO upon the effective date of each transfer or assignment (other than to an intermediate purchaser) to such Purchasing Lender and/or Purchasing CLO.

(f) Each Borrower authorizes each Lender to disclose to any Transferee and any prospective Transferee any and all financial information in such Lender’s possession concerning such Borrower which has been delivered to such Lender by or on behalf of such Borrower pursuant to this Agreement or in connection with such Lender’s credit evaluation of such Borrower; provided that the Transferee or prospective Transferee agrees to be bound by a non-disclosure agreement approved by Borrowers pursuant to which Borrowers are third party beneficiaries.

(g) Notwithstanding anything to the contrary in this Section 16.3: (i) no sale, transfer or assignment of all or any portion of any Lender’s rights and obligations under or relating to Loans under this Agreement shall be made to any Credit Party or any of their respective Affiliates.

16.4. Application of Payments. Subject to application of payments and proceeds in accordance with Section 11.5, Agent shall have the continuing and exclusive right to apply or reverse and re-apply any payment and any and all proceeds of Collateral to any portion of the Obligations or Sand Tiger’s Obligations, as applicable. To the extent that any Borrower makes a payment or Agent or any Lender receives any payment or proceeds of the Collateral for any Borrower’s benefit, which are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver, custodian or any other party under any bankruptcy law, common law or equitable cause, then, to such extent, the Obligations or part thereof intended to be satisfied shall be revived and continue as if such payment or proceeds had not been received by Agent or such Lender.

16.5. Indemnity. Each Credit Party shall defend, protect, indemnify, pay and save harmless Agent, Issuer, each Lender and each of their respective officers, directors, Affiliates, attorneys, employees and agents (each an “Indemnified Party”) for and from and against any and all claims, demands, liabilities, obligations, losses, damages, penalties, fines, actions, judgments, suits, costs, charges, expenses and disbursements of any kind or nature whatsoever (including reasonable fees and disbursements of counsel (including allocated costs of internal counsel)) (collectively, “Claims”) which may be imposed on, incurred by, or asserted against any Indemnified Party (provided, Sand Tiger shall only be liable for any indemnification obligations hereunder to the extent related to Sand Tiger’s Obligations or attributable to its assets) in, arising out of, or in any way relating to, or as a consequence, direct or indirect, of: (a) this Agreement, the Other Documents, the Advances and other Obligations and/or the transactions contemplated hereby including the Transactions, (b) any action or failure to act or action taken only after delay or the satisfaction of any conditions by any Indemnified Party in connection with and/or relating to the negotiation, execution, delivery or administration of the Agreement and the Other Documents, the credit facilities established hereunder and thereunder and/or the transactions contemplated hereby including the Transactions, (c) any Credit Party’s failure to observe,

perform or discharge any of its covenants, obligations, agreements or duties under or breach of any of the representations or warranties made in this Agreement and the Other Documents, (d) the enforcement of any of the rights and remedies of Agent, Issuer or any Lender under the Agreement and the Other Documents, (e) any threatened or actual imposition of fines or penalties, or disgorgement of benefits, for violation of any Anti-Terrorism Law by any Credit Party, any Affiliate or Subsidiary of any Credit Party, (f) any claim, litigation, proceeding or investigation instituted or conducted by any Governmental Body or instrumentality or any other Person with respect to any aspect of, or any transaction contemplated by, or referred to in, or any matter related to, this Agreement or the Other Documents, whether or not brought by any Credit Party, any director, equity holder or creditor thereof, any Indemnified Party or any other Person and whether or not any Indemnified Party is a party thereto and (g) arising from or incurred by reason of the handling of the financing arrangements of Borrowers as provided in Section 15.1, reliance by Agent or any Lender on any request or instruction from Borrowing Agent or any other action taken by Agent or any Lender with respect to Section 15.1; provided, however, notwithstanding anything in this Section 16.5, to the contrary, no Credit Party shall be required to indemnify any Indemnified Party for any Claim which, in each case is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from (x) such Indemnified Party’s own gross negligence or willful misconduct or that of its respective Affiliates or each of their respective officers, directors, employees, advisors and agents, (y) a claim brought by Borrower against an Indemnified Party for breach, in bad faith, of such Indemnified Party’s obligations to make Advances hereunder, or (z) any dispute solely among Indemnified Parties and not involving a Credit Party or any Subsidiary or Affiliate thereof and not arising out of or in connection with, in each case is found in a final non-appealable judgment by a court of competent jurisdiction, (i) the Agent’s or its Affiliates’ respective capacities in connection with this Agreement or in fulfilling their roles as Agent, arranger or bookrunner or (ii) any action or inaction of a Credit Party, any of its Subsidiaries or Affiliates. Without limiting the generality of any of the foregoing (but subject to clauses (x)-(z) above), each Credit Party shall defend, protect, indemnify, pay and save harmless each Indemnified Party from (A) any Claims which may be imposed on, incurred by, or asserted against any Indemnified Party arising out of or in any way relating to or as a consequence, direct or indirect, of the issuance of any Letter of Credit hereunder and (B) any Claims which may be imposed on, incurred by, or asserted against any Indemnified Party under any Environmental Laws with respect to or in connection with the Real Property, any Hazardous Discharge, the presence of any Hazardous Substances affecting the Real Property (whether or not the same originates or emerges from the Real Property or any contiguous real estate), including any Claims consisting of or relating to the imposition or assertion of any Lien on any of the Real Property under any Environmental Laws and any loss of value of the Real Property as a result of the foregoing except to the extent such loss, liability, damage and expense is attributable to any Hazardous Discharge resulting from actions on the part of Agent or any Lender. The Credit Parties’ obligations under this Section 16.5 shall arise upon the discovery of the presence of any Hazardous Substances in reportable quantities at the Real Property, whether or not any federal, state, or local environmental agency has taken or threatened any action in connection with the presence of any Hazardous Substances, in each such case except to the extent that any of the foregoing arises out of the gross negligence or willful misconduct of the Indemnified Party (as determined by a court of competent jurisdiction in a final and non-appealable judgment). Without limiting the generality of the foregoing (but subject to clauses (x)-(z) above), this indemnity shall extend to any liabilities,

obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever (including reasonable fees and disbursements of counsel) asserted against or incurred by any of the Indemnified Parties by any Person under any Environmental Laws or similar laws by reason of any Borrower’s or any other Person’s failure to comply with laws applicable to solid or hazardous waste materials, including Hazardous Substances and Hazardous Waste, or other Toxic Substances. No Indemnified Person shall be liable for any damage arising from the use by others of information relating to the Credit Parties obtained through electronic, telecommunications or other information systems, except to the extent such damages are found by a final, non-appealable judgment of a court to arise from the gross negligence or willful misconduct of such Indemnified Person. This Section 16.5 shall not apply to Taxes. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, THIS INDEMNITY SHALL EXTEND TO ANY LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER (INCLUDING FEES AND DISBURSEMENTS OF COUNSEL) ASSERTED AGAINST OR INCURRED BY ANY OF THE INDEMNIFIED PARTIES BY ANY PERSON UNDER ANY ENVIRONMENTAL LAWS OR SIMILAR LAWS BY REASON OF ANY BORROWER’S OR ANY OTHER PERSON’S FAILURE TO COMPLY WITH LAWS APPLICABLE TO SOLID OR HAZARDOUS WASTE MATERIALS, INCLUDING HAZARDOUS SUBSTANCES AND HAZARDOUS WASTE, OR OTHER TOXIC SUBSTANCES. ADDITIONALLY, IF ANY TAXES (EXCLUDING TAXES IMPOSED UPON OR MEASURED SOLELY BY THE NET INCOME OF AGENT AND LENDERS, BUT INCLUDING ANY INTANGIBLES TAXES, STAMP TAX, RECORDING TAX OR FRANCHISE TAX) SHALL BE PAYABLE BY AGENT, LENDERS OR BORROWERS ON ACCOUNT OF THE EXECUTION OR DELIVERY OF THIS AGREEMENT, OR THE EXECUTION, DELIVERY, ISSUANCE OR RECORDING OF ANY OF THE OTHER DOCUMENTS, OR THE CREATION OR REPAYMENT OF ANY OF THE OBLIGATIONS HEREUNDER, BY REASON OF ANY APPLICABLE LAW NOW OR HEREAFTER IN EFFECT, BORROWERS WILL PAY (OR WILL PROMPTLY REIMBURSE AGENT AND LENDERS FOR PAYMENT OF) ALL SUCH TAXES, INCLUDING INTEREST AND PENALTIES THEREON, AND WILL INDEMNIFY AND HOLD THE INDEMNIFIED PARTIES HARMLESS FROM AND AGAINST ALL LIABILITY IN CONNECTION THEREWITH.

16.8. Severability. If any part of this Agreement is contrary to, prohibited by, or deemed invalid under Applicable Laws, such provision shall be inapplicable and deemed omitted to the extent so contrary, prohibited or invalid, but the remainder hereof shall not be invalidated thereby and shall be given effect so far as possible.

16.10. Injunctive Relief. Each Borrower recognizes that, in the event any Borrower fails to perform, observe or discharge any of its obligations or liabilities under this Agreement, or threatens to fail to perform, observe or discharge such obligations or liabilities, any remedy at law may prove to be inadequate relief to Lenders; therefore, Agent, if Agent so requests, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving that actual damages are not an adequate remedy.

16.11. Consequential Damages. Neither Agent nor any Lender, nor any agent or attorney for any of them, shall be liable to any Credit Party (or any Subsidiary of any such Person) for indirect, punitive, exemplary or consequential damages arising from any breach of contract, tort or other wrong relating to the establishment, administration or collection of the Obligations or as a result of any transaction contemplated under this Agreement or any Other Document.

Such authorization shall survive the repayment of the other Obligations and the termination of this Agreement. Notwithstanding any non-disclosure agreement or similar document executed by Agent in favor of any Borrower or any of any Borrower’s affiliates, the provisions of this Agreement shall supersede such agreements.

16.16. Publicity. Each Borrower and each Lender hereby authorizes Agent to make appropriate announcements of the financial arrangement entered into among Borrowers, Agent and Lenders, including announcements which are commonly known as tombstones, in such publications and to such selected parties as Agent shall in its sole and absolute discretion deem appropriate.

(a) Each Lender or assignee or participant of a Lender that is not incorporated under the Laws of the United States of America or a state thereof (and is not excepted from the certification requirement contained in Section 313 of the USA PATRIOT Act and the applicable regulations because it is both (i) an affiliate of a depository institution or foreign bank that maintains a physical presence in the United States or foreign country, and (ii) subject to supervision by a banking authority regulating such affiliated depository institution or foreign bank) shall deliver to the Agent the certification, or, if applicable, recertification, certifying that such Lender is not a “shell” and certifying to other matters as required by Section 313 of the USA PATRIOT Act and the applicable regulations: (1) within ten (10) days after the Closing Date, and (2) as such other times as are required under the USA PATRIOT Act.

(b) Each Lender that is subject to the PATRIOT Act and Agent (for itself and not on behalf of any Lender) hereby notifies the Borrowers that pursuant to the requirements of the PATRIOT Act, it is required to obtain, verify and record information that identifies the Borrowers, which information includes the name and address of the Borrowers and other information that will allow such Lender or Agent, as applicable, to identify the Borrowers in accordance with the PATRIOT Act. The Borrowers shall, promptly following a request by Agent or any Lender, provide all documentation and other information that Agent or such Lender reasonably requests in order to comply with its ongoing obligations under applicable “know your customer” and anti-money-laundering rules and regulations, including the PATRIOT Act.

(a) Each Borrower represents and warrants that (i) no Covered Entity is a Sanctioned Person and (ii) no Covered Entity, either in its own right or through any third party, (A) has any of its assets in a Sanctioned Country or in the possession, custody or control of a Sanctioned Person in violation of any Anti-Terrorism Law; (B) does business in or with, or derives any of its income from investments in or transactions with, any Sanctioned Country or Sanctioned Person in violation of any Anti-Terrorism Law; or (C) engages in any dealings or transactions prohibited by any Anti-Terrorism Law.

(b) Each of Borrowers jointly and severally hereby irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor and primary obligor, joint and several liability with the other Borrowers with respect to the payment and performance of all of the Obligations, it being the intention of the parties hereto that all the Obligations shall be the joint and several obligations of each of Borrowers without preferences or distinction among them; provided, however, Sand Tiger shall only be liable for the Sand Tiger Obligations.

(c) If and to the extent that any of the Borrowers shall fail to make any payment with respect to any of the Obligations as and when due or to perform any of the Obligations in accordance with the terms thereof, then in each such event, the other Borrowers will make such payment with respect to, or perform, such Obligation; provided, however, that Sand Tiger’s liability shall be limited to Sand Tiger’s Obligations.

(d) The obligations of each Borrower under the provisions of this Section 16.19 constitute full recourse obligations of such Borrower, enforceable against it to the full extent of its properties and assets, irrespective of the validity, regularity or enforceability of this Agreement or any other circumstances whatsoever.

(e) Except as otherwise expressly provided herein, each Borrower hereby waives notice of acceptance of its joint and several liability, notice of any Advance made under this Agreement, notice of occurrence of any Event of Default, or of any demand for any payment under this Agreement (except as otherwise provided herein), notice of any action at any time taken or omitted by any Lender under or in respect of any of the Obligations, any requirement of diligence and, generally, all demands, notices and other formalities of every kind in connection with this Agreement. Each Borrower hereby assents to, and waives notice of, any extension or postponement of the time for the payment of any of the Obligations, the acceptance of any partial payment thereon, any waiver, consent or other action or acquiescence by any Lender at any time or times in respect of any default by any Borrower in the performance or satisfaction of any term, covenant, condition or provision of this Agreement, any and all other indulgences whatsoever by any Lender in respect of any of the Obligations, and the taking, addition, substitution or release, in whole or in part, at any time or times, of any security for any of the Obligations or in part, at any time or times, of any security for any of the Obligations or the addition, substitution or release, in whole or in part, of any Borrower. Without limiting the generality of the foregoing, each Borrower assents to any other action or delay in acting or failure to act on the part of any Lender, including, without limitation, any failure strictly or diligently to assert any right or to pursue any remedy or to comply fully with the applicable laws or regulations thereunder which might, but for the provisions of this Section 16.19, afford grounds for terminating, discharging or relieving such Borrower, in whole or in part, from any of its obligations under this Section 16.19, it being the intention of each Borrower that, so long as any of the Obligations remain unsatisfied, the obligations of such Borrower under this Section 16.19 shall not be discharged except by performance and then only to the extent of such performance or except as otherwise agreed in writing in accordance with Section 16.2. The Obligations of each Borrower under this Section 16.19 shall not be diminished or rendered unenforceable by any winding up, reorganization, arrangement, liquidation, reconstruction or similar proceeding with respect to any Borrower or any Lender. The joint and several liability of Borrowers hereunder shall continue in full force and effect notwithstanding any absorption, merger, amalgamation or any other change whatsoever in the name, membership, constitution or place of formation of any Borrower or any Lender.

(f) The provisions of this Section 16.19 are made for the benefit of the Lenders and their respective successors and assigns, and may be enforced by any such Person from time to time against any of the Borrowers as often as occasion therefor may arise and without requirement on the part of any Lender first to marshal any of its claims or to exercise any

of its rights against any of the other Borrowers or to exhaust any remedies available to it against any of the other Borrowers or to resort to any other source or means of obtaining payment of any of the Obligations or to elect any other remedy. The provisions of this Section 16.19 shall remain in effect until all the Obligations shall have been paid in full or otherwise fully satisfied. If at any time, any payment, or any part thereof, made in respect of any of the Obligations, is rescinded or must otherwise be restored or returned by any Lender upon the insolvency, bankruptcy or reorganization of any of the Borrowers, or otherwise, the provisions of this Section 16.19 will forthwith be reinstated in effect, as though such payment had not been made.

(g) Notwithstanding any provision to the contrary contained herein or in any other of the Other Documents, to the extent the joint obligations of a Borrower shall be adjudicated to be invalid or unenforceable for any reason (including, without limitation, because of any applicable state or federal law relating to fraudulent conveyances or transfers) then the obligations of each Borrower hereunder shall be limited to the maximum amount that is permissible under Applicable Law (whether federal or state and including, without limitation, any federal or state bankruptcy laws).

(h) Borrowers hereby agree, as among themselves, that if any Borrower shall become an Excess Funding Borrower (as defined below), each other Borrower shall, on demand of such Excess Funding Borrower (but subject to the next sentence hereof and to subsection (B) below), pay to such Excess Funding Borrower an amount equal to such Borrower’s Pro Rata Share (as defined below and determined, for this purpose, without reference to the properties, assets, liabilities and debts of such Excess Funding Borrower) of such Excess Payment (as defined below). The payment obligation of any Borrower to any Excess Funding Borrower under this Section 16.19(h) shall be subordinate and subject in right of payment to the prior payment in full of the Obligations of such Borrower under the other provisions of this Agreement, and such Excess Funding Borrower shall not exercise any right or remedy with respect to such excess until payment and satisfaction in full of all of such Obligations. For purposes hereof, (i) “Excess Funding Borrower” shall mean, in respect of any Obligations arising under the other provisions of this Agreement (hereafter, the “Joint Obligations”), a Borrower that has paid an amount in excess of its Pro Rata Share of the Joint Obligations; (ii) “Excess Payment” shall mean, in respect of any Joint Obligations, the amount paid by an Excess Funding Borrower in excess of its Pro Rata Share of such Joint Obligations; and (iii) “Pro Rata Share”, for the purposes of this Section 16.19(h), shall mean, for any Borrower, the ratio (expressed as a percentage) of (A) the amount by which the aggregate present fair salable value of all of its assets and properties exceeds the amount of all debts and liabilities of such Borrower (including contingent, subordinated, unmatured, and unliquidated liabilities, but excluding the obligations of such Borrower hereunder) to (B) the amount by which the aggregate present fair salable value of all assets and other properties of such Borrower and all of the other Borrowers exceeds the amount of all of the debts and liabilities (including contingent, subordinated, unmatured, and unliquidated liabilities, but excluding the obligations of such Borrower and the other Borrowers hereunder) of such Borrower and all of the other Borrowers, all as of the Closing Date (if any Borrower becomes a party hereto subsequent to the Closing Date, then for the purposes of this Section 16.19(h) such subsequent Borrower shall be deemed to have been a Borrower as of the Closing Date and the information pertaining to, and only pertaining to, such Borrower as of the date such Borrower became a Borrower shall be deemed true as of the Closing Date)

notwithstanding the payment obligations imposed on Borrowers in this Section, the failure of a Borrower to make any payment to an Excess Funding Borrower as required under this Section shall not constitute an Event of Default.

16.20. No Advisory or Fiduciary Responsibility. In connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other modification hereof or of any Other Document), each Borrower acknowledges and agrees, and acknowledges its Affiliates’ understanding, that: (a) (i) no fiduciary, advisory or agency relationship between the Borrowers and their Subsidiaries and Agent, any Issuer, any Swing Loan Lender or any Lender is intended to be or has been created in respect of the transactions contemplated hereby or by the Other Documents, irrespective of whether Agent, any Issuer, any Swing Loan Lender or any Lender has advised or is advising the Borrowers or any Subsidiary on other matters, (ii) the arranging and other services regarding this Agreement provided by the Agent, the Issuers, the Swing Loan Lenders and the Lenders are arm’s-length commercial transactions between the Borrowers and their Affiliates, on the one hand, and the Agent, the Issuers, the Swing Loan Lenders and the Lenders, on the other hand, (iii) the Borrowers have consulted their own legal, accounting, regulatory and tax advisors to the extent that each has deemed appropriate and (iv) the Borrowers are capable of evaluating, and understands and accepts, the terms, risks and conditions of the transactions contemplated hereby and by the Other Documents; and (b) (i) the Agent, the Issuers, the Swing Loan Lenders and the Lenders each is and has been acting solely as a principal and, except as expressly agreed in writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary for the Borrowers or any of their Affiliates, or any other Person; (ii) none of the Agent, the Issuers, the Swing Loan Lenders and the Lenders has any obligation to the Borrowers or any of their Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the Other Documents; and (iii) the Agent, the Issuers, the Swing Loan Lenders and the Lenders and their respective Affiliates may be engaged, for their own accounts or the accounts of customers, in a broad range of transactions that involve interests that differ from those of the Borrowers and their Affiliates, and none of the Agent, the Issuers, the Swing Loan Lenders and the Lenders has any obligation to disclose any of such interests to the Borrowers or their Affiliates. To the fullest extent permitted by Law, each Borrower hereby waives and releases any claims that it may have against the Agent, the Issuers, the Swing Loan Lenders and the Lenders with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby.

16.21. Canadian Anti-Money Laundering Legislation. Each Borrower acknowledges that, pursuant to the Proceeds of Crime Money Laundering and Terrorist Financing Act (Canada) and other applicable anti-money laundering, anti-terrorist financing, government sanction and “know your client” laws, under the laws of Canada (collectively, including any guidelines or orders thereunder, “AML Legislation”), Agent and Lenders may be required to obtain, verify and record information regarding each Borrower, its respective directors, authorized signing officers, direct or indirect shareholders or other Persons in control of such Borrower, and the transactions contemplated hereby. Borrowing Agent shall promptly provide all such information, including supporting documentation and other evidence, as may be reasonably requested by any Lender or Agent, or any prospective assign or participant of a Lender or Agent, necessary in order to comply with any applicable AML Legislation, whether now or hereafter in existence.

If Agent has ascertained the identity of any Borrower or any authorized signatories of any Borrower for the purposes of applicable AML Legislation, then the Agent:

(a) shall be deemed to have done so as an agent for each Lender, and this Agreement shall constitute a “written agreement” in such regard between each Lender and the Agent within the meaning of applicable AML Legislation; and

(b) shall provide to each Lender copies of all information obtained in such regard without any representation or warranty as to its accuracy or completeness.

Notwithstanding the provisions of this Section and except as may otherwise be agreed in writing, each Lender agrees that Agent has no obligation to ascertain the identity of the Borrowers or any authorized signatories of the Borrowers on behalf of any Lender, or to confirm the completeness or accuracy of any information it obtains from the Borrowers or any such authorized signatory in doing so.

Each of the parties has signed this Agreement as of the day and year first above written.
