If there occurs after the Closing Date any change in GAAP that affects in any respect the calculation of any covenant contained in this Agreement or the definition of any term defined under GAAP used in such calculations, Agent, Lenders and Borrowers shall negotiate in good faith to amend the provisions of this Agreement that relate to the calculation of such covenants with the intent of having the respective positions of Agent, Lenders and Borrowers after such change in GAAP conform as nearly as possible to their respective positions as of the Closing Date, provided, that, until any such amendments have been agreed upon, the covenants in this Agreement shall be calculated as if no such change in GAAP had occurred and Borrowers shall provide additional financial statements or supplements thereto, attachments to Compliance Certificates and/or calculations regarding financial covenants as Agent may reasonably require in order to provide the appropriate financial information required hereunder with respect to Borrowers both reflecting any applicable changes in GAAP and as necessary to demonstrate compliance with the financial covenants before giving effect to the applicable changes in GAAP.

Unless otherwise provided, all financial calculations shall be performed with Inventory valued at the lower of cost or market value, determined by the Borrowing Agent in accordance with its customary accounting procedures. 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 a senior officer of any Borrower or (ii) the knowledge that a senior officer would have obtained if he/she had engaged in a 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.

1.5 LIBOR Notification. Section 3.8.2 provides a mechanism for determining an alternative rate of interest in the event that the London interbank offered rate is no longer available or in certain other circumstances. The Agent does not warrant or accept any responsibility for and shall not have any liability with respect to, the administration, submission or any other matter related to the London interbank offered rate or other rates in the definition of “LIBOR Rate” or with respect to any alternative or successor rate thereto, or replacement rate therefor.

II. ADVANCES, PAYMENTS.

2.1 Revolving Advances.

(a) Amount of Revolving Advances. Subject to the terms and conditions set forth in this Agreement specifically including 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 Revolving 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 85% (the “Domestic Receivables Advance Rate”) of Eligible Domestic Receivables, plus

(ii) up to 85% of the value of the Eligible Foreign Receivables (the “Foreign Receivables Advance Rate”), plus

(iii) the lesser of (A) up to 85% of Eligible Unbilled Receivables (the “Unbilled Receivables Advance Rate”), or (B) $25,000,000 in the aggregate at any one time, plus

(iv) the least of (A) up to 50% of the value of the Eligible Inventory (the “Inventory Advance Rate”), (B) up to 85% of NOLV Percentage of the value of Eligible Inventory (the “Inventory NOLV Advance Rate”), or (C) 20% of the lesser of (I) the sum of Section 2.1(a)(y)(i), Section 2.1(a)(y)(ii), Section 2.1(a)(y)(iii) and the lesser of Sections 2.1(a)(y)(iv)(A) and (B), and (II) the Maximum Revolving Advance Amount, in each case in the aggregate at any one time, plus

(v) the lesser of (A) the Multi-Client Data Library Advance Rate of the net orderly liquidation value of the Eligible Multi-Client Data Library Assets pursuant to the most recent NOLV Appraisal, or (B) $28,500,000 in the aggregate at any one time, minus

(vi) the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit and the aggregate outstanding amount of Swing Loans, minus

(vii) the Royalty Payable Reserve, minus

(viii) such reserves as Agent may in its Permitted Discretion deem proper and necessary from time to time.

The amount derived from the sum of (x) Sections 2.1(a)(y)(i), (ii), (iii), (iv) and (v) minus (y) Sections 2. l(a)(y)(vi), (vii) and (viii) at any time and from time to time shall be referred to as the “Formula Amount”. Notwithstanding the foregoing, the parties agree that at any given time the maximum Formula Amount attributable to GX Mexico, excluding amounts added under clause (v), shall not exceed $5,000,000 (such Indebtedness, the “GX Mexico 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, provided that any decrease in the Advance Rates or any other exercise of Permitted Discretion that has the effect of reducing the Formula Amount shall not apply until five (5) Business Days after Agent shall have notified Borrowing Agent thereof in writing. 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. 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, subject to Section 2.1(b) above. 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 $1,000,000 and in integral multiples of $500,000 thereafter, and (iii) the duration of the first Interest Period therefor. Interest Periods for LIBOR Rate Loans shall be for one, two or three 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. Any Interest Period that begins on the last Business Day of a calendar month (or a day for which there is no numerically corresponding day in the last calendar month of such Interest Period) shall end on the last Business Day of the last calendar month of such Interest Period. 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, no LIBOR Rate Loan shall be made available to any Borrower. 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 Interest 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 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 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 in the payment of the principal of or interest on any LIBOR Rate Loan or failure by any 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; provided that GX Mexico shall only be liable for amounts attributable to the GX Mexico Obligations. 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.

(i) Anything to the contrary contained herein notwithstanding, neither Agent nor any Lender, nor any of their participants, is actually required to acquire LIBOR deposits to fund or otherwise match fund any Obligation as to which interest accrues based on the LIBOR Rate. The provisions set forth herein shall apply as if each Lender or its participants had match funded any Obligation as to which interest is accruing based on the LIBOR Rate by acquiring LIBOR deposits for each Interest Period in the amount of the LIBOR Rate Loans.

2.3 Reserved.

2.4 Swing Loans.

(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 Revolving 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. 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 Revolving 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 Revolving 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 Revolving Commitment Percentage. Swing Loan Lender or Agent may, at any time, require the Lenders holding Revolving 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 Revolving Commitment is required to fund, and funds, its participation in any Swing Loans purchased hereunder, Agent shall promptly distribute to such Lender its Revolving 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 Revolving Commitment shall be obligated in any event to make Revolving Advances in an amount in excess of its Revolving 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 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 or deemed 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.

2.6 Making and Settlement of Advances.

(a) Each borrowing of Revolving Advances shall be advanced according to the applicable Revolving Commitment Percentages of Lenders holding the Revolving 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 Revolving 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 Revolving Commitment that such Lender will not make the amount which would constitute its applicable Revolving 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. In such event, if a Lender has not in fact made its applicable Revolving 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 Revolving 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 Revolving 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 Revolving 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 Revolving Commitment shall transfer the amount of such Lender's Revolving 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 Revolving 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 Revolving 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.

2.8 Manner and Repayment of Advances.

(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 of an Event of Default under this Agreement or (y) termination of this Agreement. Each payment (including each prepayment) by any Borrower 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 Revolving Commitment Percentages of Lenders, to the outstanding Revolving Advances (subject to any contrary provisions of Section 2.22) with application first to Revolving Advances comprising Domestic Rate Loans and thereafter to Revolving Advances comprising LIBOR Rate Loans.

(b) [Reserved.]

(c) All payments of principal, interest and other amounts payable hereunder, or under any of the Other Documents shall be made to Agent without deduction, setoff or counterclaim and 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. At any time during which a Cash Dominion Trigger Event shall have occurred and then be continuing, Agent shall have the right to effectuate payment of any and all Obligations due and owing hereunder by charging Borrowers' Account or by making Advances as provided in Section 2.2 hereof.

(d) At any time during which a Cash Dominion Trigger Event shall have occurred and then be continuing, all proceeds received by Agent shall be applied to the Obligations (other than Hedge Liabilities and Cash Management Liabilities) in accordance with Section 4.8(h).

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 due and payable promptly, but in any event within three (3) Business Days of 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, a loan account (“Borrowers' Account”) in the name of Borrowers in which shall be recorded the date and amount of each Advance made by Agent or Lenders in accordance with this Agreement 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 Borrowers' Account shall be conclusive evidence absent manifest error of the amounts of Advances and other charges thereto and of payments applicable thereto.

2.11 Letters of Credit.

(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 (including for the support of the obligations of any Subsidiary of a 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.

2.12 Issuance of Letters of Credit.

(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 three (3) 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, or 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 (provided that any Letter of Credit may, if requested by Borrowing Agent, provide for renewal thereof for additional periods of up to twelve (12) months), but 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 (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.

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

2.13 Requirements for Issuance of Letters of Credit.

(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 Issuer to deliver to Agent all instruments, documents, and other writings and property received by 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, 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 is continuing: (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 (“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.

2.14 Disbursements, Reimbursement.

(a) Immediately upon the issuance of each Letter of Credit, each Lender holding a Revolving 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 Revolving 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. Promptly following receipt of 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; provided that GX Mexico shall only be liable for amounts attributable to the GX Mexico Obligations. 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 Revolving 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 Revolving 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; provided that GX Mexico shall only be liable for amounts attributable to the GX Mexico Obligations. 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 Revolving 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 Revolving 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 Revolving Commitment so notified fails to make available to Agent, for the benefit of Issuer, the amount of such Lender's Revolving 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 Revolving 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 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.

2.15 Repayment of Participation Advances.

(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 Revolving Commitment, in the same funds as those received by Agent, the amount of such Lender's Revolving Commitment Percentage of such funds, except Agent shall retain the amount of the Revolving Commitment Percentage of such funds of any Lender holding a Revolving 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 Revolving 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, 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 Revolving 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 Revolving 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;

(iii) any lack of validity or enforceability of any Letter of Credit;

(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, sufficiency, 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;

(ix) the occurrence of any Material Adverse Effect;

(x) any breach of this Agreement or any Other Document by any party thereto;

(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;

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

(xiv) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

2.19 Liability for Acts and Omissions.

(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. In furtherance and not in limitation of the

foregoing, Issuer shall not be responsible for: (i) the form, validity, sufficiency, 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 nonappealable 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.

2.20 Mandatory Prepayments: Voluntary Reductions of Revolving Commitments.

(a) Subject to Section 7.1 hereof, when any Loan Party sells or otherwise disposes of any Collateral other than (x) Inventory in the Ordinary Course of Business, or (y) pursuant to or in connection with the INOVA Transaction, Borrowers shall repay the Advances (if any are then outstanding) in an amount equal to the net cash proceeds of such sale (i.e., gross cash proceeds less the reasonable direct costs of such sales or other dispositions), such repayments to be made promptly but in no event more than three (3) Business Days following receipt of such net proceeds, and until the date of payment, such proceeds shall be held in trust for Agent; provided, however, that no such repayment shall be required to the extent Borrowers notified Agent that such net cash proceeds will instead be applied to replace such Collateral with productive assets of a kind used or useable in the business of the Loan Parties; provided, further, that if such net cash proceeds constituting proceeds of Collateral other than Eligible Domestic Receivables, Eligible Foreign Receivables, Eligible Unbilled Receivables and Eligible Inventory are received or being held by such Loan Party during a Cash Dominion Trigger Event, Agent shall establish a reserve in the amount of such net cash proceeds, which reserve shall become permanent to the extent such net cash proceeds have not been applied to replace such Collateral with productive assets of a kind used or useable in the business of the Loan Parties within three hundred sixty (360) days after the applicable Loan Party's receipt of such net cash proceeds; provided, further, that if such net cash proceeds constituting proceeds of Collateral relating to Borrower’s interest in its Multi-Client Data Library are received or being held by such Loan Party during a Cash Dominion Trigger Event, Agent shall establish a reserve in the amount of such net cash proceeds, which reserve shall become permanent to the extent such net cash proceeds have not been applied to replace such Collateral with productive assets of a kind used or useable in the business of the Loan Parties within one hundred eighty (180) days after the applicable Loan Party's receipt of such net cash proceeds. 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 Advances (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. Notwithstanding the foregoing, so long as no Event of Default has occurred and is continuing, the proceeds from any sale of Borrower’s interest in its Multi-Client Data Library pursuant to Section 7.1(b)(v) hereof may be retained by the Borrowers for general corporate purposes.

(b) [Reserved.]

(c) In the event of any issuance or other incurrence of Indebtedness (other than Permitted Indebtedness) by any Borrower, Borrowers shall, no later than three (3) Business Days

after the receipt by the applicable Borrower of the cash proceeds from any such incurrence of Indebtedness, repay the Advances (if any) in an amount equal to the lesser of (x) one hundred percent (100%) of such cash proceeds in the case of such incurrence or issuance of Indebtedness and (y) the amount of such Advances. Such repayments will be applied in the same manner as set forth in Section 2.20(a) hereof.

(d) 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 Loan Party, 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; provided, however, that no such repayment shall be required to the extent the Borrowing Agent has notified Agent that such proceeds will instead be applied to replace such assets or property with productive assets of a kind used or useable in the business of the Loan Parties; provided, further, that if such proceeds have not been applied to replace such assets or property with productive assets of a kind used or useable in the business of the Loan Parties within one hundred eighty (180) days after the applicable Loan Party's receipt of such proceeds, Borrowers shall repay the Advances in an amount equal to such proceeds of such sale on the next Business Day.

(e) Subject to Section 2.2(g) hereof, Borrowers may, at their option from time to time, permanently reduce the aggregate Revolving Commitments upon at least five (5) days prior written notice to Agent, which notice shall specify the amount of the reduction and shall be irrevocable once given, provided that a notice of reduction of the Revolving Commitments delivered by any Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by such Borrower (by notice to Agent on or prior to the specified effective date) if such condition is not satisfied. Each reduction shall be in a minimum amount of $10,000,000 or an increment of $5,000,000 in excess thereof and shall not reduce the aggregate Revolving Commitments to an amount less than the aggregate amount of Advances outstanding at such time.

Notwithstanding to foregoing, GX Mexico shall only be liable for amounts attributable to the GX Mexico Obligations.

2.21 Use of Proceeds.

(a) Borrowers shall apply the proceeds of Advances to (i) pay fees and expenses relating to this transaction, and (ii) provide for its general corporate needs, including its working capital requirements, capital expenditures, surety deposits and acquisition financing.

(b) Without limiting the generality of Section 2.21(a) above, neither 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.

2.22 Defaulting Lender.

(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 Revolving Commitments which are not Defaulting Lenders based on their respective Revolving Commitment Percentages, and no Revolving 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 Revolving Commitment in accordance with their Revolving 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(b) 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 Revolving 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 Revolving Commitments in proportion to the respective Revolving 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 Revolving 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 Revolving 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 (1) 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 Revolving 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 Revolving Commitments pursuant to Section 3.2(a) shall be adjusted and reallocated to Non-Defaulting Lenders holding Revolving 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 Revolving 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 Revolving 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 Revolving 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 Revolving 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 Revolving Commitment, then Participation Commitments of Lenders holding Revolving 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 Revolving 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 Revolving Commitment Percentage.

(f) So long as any Lender 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 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 as 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 the GX Mexico Obligations 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 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, 4.4, 4.7, 6.4, 6.6, 6.7 and 6.8 hereof, and all amounts so charged shall be added to the Obligations or the GX Mexico Obligations and shall be secured by the Collateral. To the extent Revolving Advances made (or deemed made) pursuant to this Section 2.23 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 Swing Loans 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, other than the GX Mexico Obligations.

III. INTEREST AND FEES.

3.1 Interest. Interest on Advances shall be payable in arrears on the first Business Day of each calendar quarter with respect to Domestic Rate Loans and, with respect to LIBOR Rate

Loans, at the end of each Interest Period; provided, 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 applicable Revolving Interest Rate and (ii) with respect to Swing Loans, the Revolving Interest Rate for Domestic Rate Loans (as applicable, the “Contract Rate”). Except as expressly provided otherwise in this Agreement, any Obligations other than the Advances (and other than Hedge Liabilities and Cash Management Liabilities) 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 applicable Contract Rate 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 (other than Hedge Liabilities and Cash Management Liabilities) shall bear interest at the applicable Contract Rate for Domestic Rate Loans plus two percent (2%) per annum (the “Default Rate”).

3.2 Letter of Credit Fees.

(a) Borrowers shall pay (x) to Agent, for the ratable benefit of Lenders holding Revolving 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 aggregate 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 Business 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 aggregate 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 Business 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 administrative, issuance, amendment, payment and negotiation charges with respect to Letters of Credit and all fees and expenses as agreed upon by Issuer and 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%) per annum.

(b) At any time following the occurrence 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 all 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 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 (other than Hedge Liabilities and Cash Management Liabilities); (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, 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 use such cash collateral to pay and satisfy such Obligations.

3.3 Facility Fee. If, for any day in each calendar quarter during the Term, (i) the average daily unpaid balance of the sum of Revolving Advances plus Swing Loans plus the Maximum Undrawn Amount of all outstanding Letters of Credit (the “Usage Amount”) for each day of such calendar quarter is greater than or equal to fifty percent (50%) of the Maximum Revolving Advance Amount, then Borrowers shall pay to Agent, for the ratable benefit of Lenders holding the Revolving Commitments based on their Revolving Commitment Percentages, a fee at a rate equal to three-quarters of one percent (0.75%) per annum on the amount by which the Maximum Revolving Advance Amount exceeds such Usage Amount, and (ii) the Usage Amount for each day of such calendar quarter is less than fifty percent (50%) of the Maximum Revolving Advance Amount, then Borrowers shall pay to Agent, for the ratable benefit of Lenders holding the Revolving Commitments based on their Revolving Commitment Percentages, a fee at a rate equal

to one percent (1.00%) per annum on the amount by which the Maximum Revolving Advance Amount on such day exceeds such Usage Amount (collectively, the “Facility Fee”). Such Facility Fee shall be payable to Agent in arrears on the first Business Day of each calendar quarter with respect to each day in the previous calendar quarter.

3.4 Fee Letter; Appraisals.

(a) Borrowers 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 out-of-pocket costs and expenses of any appraisals conducted pursuant to, and for which Borrowers are responsible in accordance with, Section 4.7 hereof shall be paid for by Borrowers when due, in full and without deduction, off-set or counterclaim.

3.5 Computation of Interest and Fees. Interest and fees hereunder shall be computed on the basis of a year of 360 days and for the actual number of days elapsed, except that interest on Domestic Rate Loans shall be computed on the basis of a year of 365/366 days 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 applicable Contract Rate during such extension.

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.

3.7 Increased Costs. In the event that any Applicable Law or 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 after the Closing Date, shall:

(a) subject Agent, Swing Loan Lender, any Lender or Issuer to any Tax 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 imposed on and 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 by an amount that Agent, Swing Loan Lender, such Lender or Issuer deems to be material or to reduce the amount of any payment (whether of principal, interest or otherwise) in respect of any of the Advances by an amount that Agent, Swing Loan Lender or such Lender or Issuer deems to be material, 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 GX Mexico shall only be liable for any such costs or expenses attributable to the GX Mexico Obligations. Agent, Swing Loan Lender, such Lender or Issuer shall certify the amount of such additional cost or reduced amount to Borrowing Agent, and such certification shall be conclusive absent manifest error.

3.8 Alternate Rate of Interest.

3.8.1. 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;

(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;

(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); or

(d) the LIBOR Rate will not adequately and fairly reflect the cost to such Lender of the establishment or maintenance of any LIBOR Rate Loan, then Agent shall give Borrowing Agent prompt written or telephonic notice of such determination. If such notice is given prior to a Benchmark Replacement Date (as defined below), (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.

3.8.2. Successor LIBOR Rate Index.

(a) Benchmark Replacement. Notwithstanding anything to the contrary herein or in any Other Document (and any agreement executed in connection with an Interest Rate Hedge shall be deemed not to be an “Other Document” for purposes of this Section 3.8.2), if a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (1) or (2) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Other Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or any Other Document and (y) if a Benchmark Replacement is determined in accordance with clause (3) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Other Document in respect of any Benchmark setting at or after 5:00 p.m. on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is provided to the Lenders without any amendment to, or further action or consent of any other party to, this Agreement or any Other Document so long as the Agent has not received, by such time, written notice of objection to such Benchmark Replacement from Lenders comprising the Required Lenders.

(b) Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any Other Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any Other Document.

(c) Notices; Standards for Decisions and Determination. The Agent will promptly notify the Borrower and the Lenders of (i) any occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date, (ii) the implementation of any Benchmark Replacement, (iii) the effectiveness of any Benchmark Replacement Conforming Changes, (iv) the removal or reinstatement of any tenor of a Benchmark pursuant to paragraph (d) below and (v) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 3.8.2, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any Other Document, except, in each case, as expressly required pursuant to this Section 3.8.2.

(d) Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any Other Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i) if the then-current Benchmark is a term rate (including Term SOFR or USD LIBOR) and either (A) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Agent in its reasonable discretion or (B) the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is or will be no longer representative, then the Agent may modify the definition of “Interest Period” for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is or will no longer be representative for a Benchmark (including a Benchmark Replacement), then the Agent may modify the definition of “Interest Period” for all Benchmark settings at or after such time to reinstate such previously removed tenor.

(e) Benchmark Unavailability Period. Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower may revoke any request for a Loan bearing interest based on USD LIBOR, conversion to or continuation of Loans bearing interest based on USD LIBOR to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any such request into a request for a Loan of or conversion to Loans bearing interest under the Base Rate. During any Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of the Base Rate based upon the then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of the Base Rate.

(f) Secondary Term SOFR Conversion. Notwithstanding anything to the contrary herein or in any Other Document and subject to the proviso below in this paragraph, if a Term SOFR Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then (i) the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder or under any Other Document in respect of such Benchmark setting (the “Secondary Term SOFR Conversion Date”) and subsequent Benchmark settings, without any amendment to, or further action or consent of any other party to, this Agreement or any Other Document; and (ii) Loans outstanding on the Secondary Term SOFR Conversion Date bearing interest based on the then-current Benchmark shall be deemed to have been converted to Loans bearing interest at the Benchmark Replacement with a tenor approximately the same length as the interest payment period of the then-current Benchmark; provided that, this paragraph (f) shall not be effective unless the Agent has delivered to the Lenders and the Borrowing Agent a Term SOFR Notice.

(g) Certain Defined Terms. As used in this Section 3.8.2:

“Available Tenor” means, as of any date of determination and with respect to the then-current Benchmark, as applicable, (x) if the then current Benchmark is a term rate or is based on a term rate, any tenor for such Benchmark that is or may be used for determining the length of an Interest Period pursuant to this Agreement as of such date and not including, for the avoidance of doubt, any tenor for such Benchmark that is then-removed from the definition of “Interest Period” pursuant to paragraph (d) of Section 3.8.2, or (y) if the then current Benchmark is not a term rate nor based on a term rate, any payment period for interest calculated with reference to such Benchmark pursuant to this Agreement as of such date.

“Benchmark” means, initially, USD LIBOR; provided that if a Benchmark Transition Event a Term SOFR Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred with respect to USD LIBOR or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement to the extent that such Benchmark Replacement has replaced such prior benchmark rate pursuant to paragraph (a) of Section 3.8.2.

“Benchmark Replacement” means, for any Available Tenor, the first alternative set forth in the order below that can be determined by the Agent for the applicable Benchmark Replacement Date:

(1) the sum of: (a) Term SOFR and (b) the related Benchmark Replacement Adjustment;

(2) the sum of: (a) Daily Simple SOFR and (b) the related Benchmark Replacement Adjustment; or

(3) the sum of: (a) the alternate benchmark rate that has been selected by the Agent and the Borrower as the replacement for the then-current Benchmark for the applicable Corresponding Tenor giving due consideration to (i) any selection or

recommendation of a replacement benchmark rate or the mechanism for determining such a rate by the Relevant Governmental Body or (ii) any evolving or then-prevailing market convention for determining a benchmark rate as a replacement for the then-current Benchmark for U.S. dollar-denominated syndicated credit facilities at such time and (b) the related Benchmark Replacement Adjustment;

provided that, in the case of clause (1), such Unadjusted Benchmark Replacement is displayed on a screen or other information service that publishes such rate from time to time as selected by the Agent in its reasonable discretion; provided, further, that, with respect to a Term SOFR Transition Event, on the applicable Benchmark Replacement Date, the “Benchmark Replacement” shall revert to and shall be determined as set forth in clause (1) of this definition. If the Benchmark Replacement as determined pursuant to clause (1), (2) or (3) above would be less than the Floor, the Benchmark Replacement will be deemed to be the Floor for the purposes of this Agreement and the Other Documents.

“Benchmark Replacement Adjustment” means, with respect to any replacement of the then-current Benchmark with an Unadjusted Benchmark Replacement for any applicable Available Tenor for any setting of such Unadjusted Benchmark Replacement:

(1) for purposes of clauses (1) and (2) of the definition of “Benchmark Replacement,” the first alternative set forth in the order below that can be determined by the Agent:

(a) the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) as of the Reference Time such Benchmark Replacement is first set for such Available Tenor that has been selected or recommended by the Relevant Governmental Body for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement for the applicable Corresponding Tenor;

(b) the spread adjustment (which may be a positive or negative value or zero) as of the Reference Time such Benchmark Replacement is first set for such Available Tenor that would apply to the fallback rate for a derivative transaction referencing the ISDA Definitions to be effective upon an index cessation event with respect to such Benchmark for the applicable Corresponding Tenor; and

(2) for purposes of clause (3) of the definition of “Benchmark Replacement,” the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected by the Agent and the Borrower for the applicable Corresponding Tenor giving due consideration to (i) any selection or recommendation of a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement by the Relevant Governmental Body on the applicable Benchmark Replacement Date or

(ii) any evolving or then-prevailing market convention for determining a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated syndicated credit facilities;

provided that, (x) in the case of clause (1) above, such adjustment is displayed on a screen or other information service that publishes such Benchmark Replacement Adjustment from time to time as selected by the Agent in its reasonable discretion and (y) if the then-current Benchmark is a term rate, more than one tenor of such Benchmark is available as of the applicable Benchmark Replacement Date and the applicable Unadjusted Benchmark Replacement will not be a term rate, the Available Tenor of such Benchmark for purposes of this definition of “Benchmark Replacement Adjustment” shall be deemed to be the Available Tenor that has approximately the same length (disregarding business day adjustments) as the payment period for interest calculated with reference to such Unadjusted Benchmark Replacement.

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “Alternate Base Rate,” the definition of “Business Day,” the definition of “Interest Period,” timing and frequency of determining rates and making payments of interest, timing of borrowing requests or prepayment, conversion or continuation notices, length of lookback periods, the applicability of breakage provisions, and other technical, administrative or operational matters) that the Agent decides may be appropriate to reflect the adoption and implementation of such Benchmark Replacement and to permit the administration thereof by the Agent in a manner substantially consistent with market practice (or, if the Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Agent determines that no market practice for the administration of such Benchmark Replacement exists, in such other manner of administration as the Agent decides is reasonably necessary in connection with the administration of this Agreement and the Other Documents).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark:

(2) in the case of clause (3) of the definition of “Benchmark Transition Event,” the date determined by the Agent, which date shall promptly follow the date of the public statement or publication of information referenced therein;

(3) in the case of a Term SOFR Transition Event, the date that is set forth in the Term SOFR Notice provided to the Lenders and the Borrower pursuant to Section 3.8.2, which date shall be at least 30 days from the date of the Term SOFR Notice; or

(4) in the case of an Early Opt-in Election, the sixth (6th) Business Day after the date notice of such Early Opt-in Election is provided to the Lenders, so long as the Agent has not received, by 5:00 p.m. on the fifth (5th) Business Day after the date notice of such Early Opt-in Election is provided to the Lenders, written notice of objection to such Early Opt-in Election from Lenders comprising the Required Lenders.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark:

(1) a public statement or publication of information by or on behalf of the administrator of such Benchmark (or the published component used in the calculation thereof) announcing that such administrator has ceased or will cease to provide all Available Tenors of such Benchmark (or such component thereof), permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide any Available Tenor of such Benchmark (or such component thereof);

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 (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, 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) by an amount deemed by Agent, Swing Loan Lender or any Lender to be material, 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 GX Mexico shall only be liable for amounts attributable to the GX Mexico 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.

3.10 Taxes.

(a) Any and all payments by or on account of any Obligations (other than Hedge Liabilities and Cash Management Liabilities) hereunder or under any Other Document shall be made free and clear of and without deduction or withholding for any Indemnified Taxes or Other Taxes; provided that if Borrowers shall be required by Applicable Law to deduct or withhold any Indemnified Taxes (including any Other Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) Agent, Swing Loan Lender, Lender, Issuer or Participant, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) Borrowers shall make such deductions or withholdings and (iii) Borrowers 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) Each Borrower shall indemnify Agent, Swing Loan Lender, each Lender, Issuer and any Participant, 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) paid by Agent, Swing Loan

Lender, such Lender, Issuer, or such Participant, as the case may be, 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 Borrowers by any Lender, Swing Loan Lender, Participant, or Issuer (with a copy to Agent), or by Agent on its own behalf or on behalf of Swing Loan Lender, a Lender or Issuer, shall be conclusive absent manifest error. Notwithstanding anything in this Agreement to the contrary, GX Mexico shall have no obligations under this Section 3.10(c)other than with respect to GX Mexico Obligations.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by any Borrower to a Governmental Body, 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.

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 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 Lender, Issuer or assignee or participant of a Lender or Issuer for the amount of any tax it deducts and withholds in accordance with regulations under § 1441 of the Code. In addition, any Lender, if requested by Borrowers or Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by Borrowers or Agent as will enable Borrowers or Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Without limiting the generality of the foregoing, in the event that any Borrower is resident for tax purposes in the United States of America, any Foreign Lender (or other Lender) shall deliver to Borrowers and Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender (or other Lender) becomes a Lender under this Agreement (and from time to time thereafter upon the request of Borrowers or Agent, but only if such Foreign Lender (or other Lender) is legally entitled to do so), whichever of the following is applicable: two (2) duly completed valid originals of IRS Form W-8BEN (or IRS Form W-8BEN-E, as applicable) claiming eligibility for benefits of an income tax treaty to which the United States of America is a party,

(iii) 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 Borrowers to determine the withholding or deduction required to be made, or

(iv) to the extent that any Lender is not a Foreign Lender, such Lender shall submit to Agent two (2) originals of an IRS Form W-9 or any other form prescribed by Applicable Law demonstrating that such Lender is not a Foreign Lender.

(f) If a payment made to a Lender, Swing Loan Lender, Participant, Issuer, or Agent 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 Lender, Swing Loan Lender, Participant, Issuer, or Agent shall deliver to the Agent (in the case of Swing Loan Lender, a Lender, Participant or Issuer) and Borrowers (A) a certification signed by the chief financial officer, principal accounting officer, treasurer or controller of such Person, and (B) other documentation reasonably requested by Agent or any Borrower sufficient for Agent and Borrowers to comply with their obligations under FATCA and to determine that Swing Loan Lender, such Lender, Participant, Issuer, or Agent has complied with such applicable reporting requirements or to determine the amount to deduct and withhold from such payment. For purposes of this Section 3.10(f). “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(g) Each Lender, Swing Loan Lender, Participant, Issuer or Agent agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify Borrowers and Agent in writing of its legal inability to do so.

(h) 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 or 3.9 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 ninety (90) 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 Agent pursuant to Section 16.2(b) hereof, as the case may be, by 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 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 Revolving 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 Agent in its good faith business judgment. 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 Revolving Commitment Percentage, then such Affected Lender shall assign, in accordance with Section 16.3 hereof, all of its Advances and its Revolving 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 (other than Hedge Liabilities and Cash Management Liabilities) then due and payable to the Affected Lender.

During such period no Borrower shall, without Agent's prior written consent, pledge, sell (except for sales or other dispositions otherwise permitted by this Agreement), assign, transfer, create or suffer to exist a Lien upon or encumber or allow or suffer to be encumbered in any way except for Permitted Encumbrances, any part of the Collateral. Each Borrower shall defend Agent's interests in the Collateral against any and all Persons whatsoever. Upon the occurrence of any

Event of Default and during the continuation thereof, 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 the foregoing right to take possession of the Collateral, Borrowers shall, upon demand, assemble it in the best manner possible and make it available to Agent at a place reasonably convenient to Agent.

4.7 Appraisals. Agent may, in its Permitted Discretion, at any time after the Closing Date, engage the services of an independent appraisal firm or firms of reputable standing, satisfactory to Agent, for the purpose of appraising the then current NOLV Percentage of each Borrower's Inventory or the net orderly liquidation value of the Collateral (each such appraisal, an “NOLV Appraisal”) (it being acknowledged that (i) so long as an Event of Default has not occurred and is then continuing, any such NOLV Appraisal shall, with respect to the net orderly liquidation value of the Multi-Client Data Library, be acceptable to Borrowers, and (ii) (X) prior to the occurrence and continuance of an Event of Default, Borrowers shall be responsible to reimburse Agent for no more than one (1) NOLV Appraisal per annum (including any additional or supplemental appraisals need to obtain an NOLV Appraisal acceptable to both Agent and the Borrowers) and (Y) after the occurrence and during the continuance of an Event of Default, there shall be no limitations on the frequency on which NOLV Appraisals may be conducted at Borrowers' expense). In addition to the foregoing, the Borrowers shall have the right to submit to an independent appraisal firm or firms of reputable standing, satisfactory to Agent, from time to time information (in reasonable detail) concerning the Multi-Client Data Library, including any additional completed portions of or collections of seismic data included in the Multi-Client Data Library, for evaluation and appraisal in order to have the net orderly liquidation value thereof included in the calculation of the Formula Amount in accordance with Section 2.1. If any Borrower

shall request such an appraisal, the Agent shall use commercially reasonable efforts to cause to be completed any such requested appraisal promptly following such request and delivery of such information, and shall provide to such Borrower the results thereof (it being acknowledged that, so long as an Event of Default has not occurred and is then continuing, any such requested appraisal shall be acceptable to Borrowers (not to be unreasonably withheld)), and following such approval, Borrower may thereafter include such net orderly liquidation value in subsequently delivered Borrowing Base Certificates. 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 any Borrower's Inventory, 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.

(f) At any time following the occurrence and during the continuation of a Cash Dominion Trigger Event, 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, at any time following the occurrence and during the continuation of an Event of Default: (A) to endorse such Borrower's name upon any notes, acceptances, checks, drafts, money orders or other evidences of payment or Collateral; (B) to sign such Borrower's name on any invoice or bill of lading relating to any of the Receivables, drafts against Customers, assignments and verifications of Receivables; (C) to send verifications of Receivables to any Customer; (D) to sign such Borrower's name on all financing statements or any other documents or instruments deemed necessary or appropriate by Agent to preserve, protect, or perfect Agent's interest in the Collateral and to file same; (E) to receive, open and dispose of all mail addressed to any Borrower at any post office box/lockbox maintained by Agent for Borrowers or at any other business premises of Agent; (F) to demand payment of the Receivables; (G) to enforce payment of the Receivables by legal proceedings or otherwise; (H) to exercise all of such Borrower's rights and remedies with respect to the collection of the Receivables and any other Collateral; (I) to extend the time of payment of, settle, adjust, compromise, extend or renew the Receivables; (J) to settle, adjust or compromise any legal proceedings brought to collect Receivables; (K) to prepare, file and sign such Borrower's name on a proof of claim in bankruptcy or similar document against any Customer; (L) 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; (M) to accept the return of goods represented by any of the Receivables; (N) to change the address for delivery of mail addressed to any Borrower to such address as Agent may designate; and (O) 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 done with gross negligence or willful misconduct

(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 (other than Hedge Liabilities and Cash Management Liabilities) remain unpaid.

(g) 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 unless such liability or damage results from Agent's or Lender's gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment).

(h) All proceeds of Collateral shall be deposited by Borrowers (other than GX Mexico) into either (i) a lockbox account, dominion account or such other “blocked account” (“Blocked Accounts”) pursuant to an arrangement reasonably acceptable to Agent or (ii) a depository account (“Depository Accounts”), in each case, established at Agent or a bank or banks (each such bank, a “Control Account Bank”) for the deposit of such proceeds; provided that proceeds of Receivables arising in connection with a Joint Data Acquisition Program may be deposited into a Joint Data Acquisition Program Account. Each applicable Borrower, Agent and each Control Account Bank shall enter into a deposit account control agreement in form and substance reasonably satisfactory to Agent that is sufficient to give Agent “control” (for purposes of Articles 8 and 9 of the Uniform Commercial Code) over such account and pursuant to which Agent may direct such Control Account Bank to transfer such funds so deposited on a daily basis to Agent, either to any account maintained by Agent at said Control Account Bank or by wire transfer to appropriate account(s) at Agent; provided that Agent shall not exercise such “control” right unless a Cash Dominion Trigger Event shall have occurred. All funds deposited in such Blocked Accounts or Depository Accounts shall immediately become subject to the security interest of Agent for its own benefit and the ratable benefit of Issuer, Lenders and all other holders of the Obligations, and Borrowing Agent shall obtain from any Control Account Bank that is not a Lender the agreement by such Control Account Bank to waive any offset rights against the funds so deposited. Neither Agent nor any Lender assumes any responsibility for such blocked account arrangement, including any claim of accord and satisfaction or release with respect to deposits accepted by any Control Account Bank thereunder.

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 $20,000,000 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 Loan Parties 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, (y) Loan Parties 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 Loan Party shall fail to respond promptly to any Hazardous Discharge or Environmental Complaint or any Loan Party shall fail to comply with any of the requirements of any Environmental Laws, 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 or advisable, to remediate, remove, mitigate or otherwise manage with any such Hazardous Discharge or Environmental Complaint. All reasonable 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 by Loan Parties upon demand, 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 Loan Party.

(d) Promptly upon the reasonable written request of Agent from time to time, Loan Parties shall provide Agent, at Borrowers' expense, with an environmental site assessment or environmental compliance audit report prepared by an environmental engineering firm acceptable in the reasonable opinion of Agent, to assess with a reasonable degree of certainty the existence of a Hazardous Discharge and the potential costs in connection with abatement, remediation and removal of any Hazardous Materials found on, under, at or within the Real Property. Any report or investigation of such Hazardous Discharge proposed and acceptable to the responsible Governmental Body shall be acceptable to Agent.

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) Intellectual Property which is 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. 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

119

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), and in no event shall Collateral supporting the GX Mexico Obligations or any property or assets of GX Mexico be used in any matter to satisfy the Obligations of any U.S. Borrower (and nothing in this Article XIV shall be construed to permit such use).

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; provided that the Agent shall not have any right to take any action that would permit the Collateral supporting the GX Mexico Obligations to be used to satisfy the Obligations of any U.S. Borrower.

11.3 Setoff. 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 U.S. Borrower’s, property held by Agent and such Lender or any of their Affiliates to reduce the Obligations of GX Mexico; provided that no Collateral supporting the GX Mexico Obligations or any assets or property of GX Mexico shall be used to satisfy the Obligations of any U.S. Borrower.

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 shall 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;

SECOND, to payment of any fees owed to Agent;

120

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;

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

provided that, for the avoidance of doubt, no Collateral supporting the GX Mexico Obligations or any assets or property of GX Mexico shall be used to satisfy the Obligations of any U.S. Borrower.

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, Cash Management Liabilities and Hedge Liabilities held by such Lender bears to the aggregate then outstanding Advances, Cash Management Liabilities and Hedge Liabilities) 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

121

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 GX Mexico shall only be applied to pay down the GX Mexico Obligations.

XII. WAIVERS AND JUDICIAL PROCEEDINGS.

12.1 Waiver of Notice. 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

122

COURT AS WRITTEN EVIDENCE OF THE CONSENTS OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

XIII. EFFECTIVE DATE AND TERMINATION.

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 the Scheduled Maturity Date, provided that this Agreement shall terminate on September 15, 2021 in the event that the Borrowers do not have sufficient unencumbered cash on-hand to cause the indefeasible payment in full of the 2016 Notes on such date without using proceeds of Revolving Advances. Borrowers may terminate this Agreement at any time upon ten (10) days prior written notice to Agent upon payment in full of the Obligations (other than Hedge Liabilities and Cash Management Liabilities) (provided that any such notice of termination may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by such Borrower (by notice to Agent on or prior to the specified effective date) if such condition is not satisfied).

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 (other than contingent Obligations not then due and payable) have been fully and 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' Account may from time to time be temporarily in a zero or credit position, until all of the Obligations (other than Hedge Liabilities and Cash Management Liabilities) of each Borrower have been paid and performed in full after the termination of this Agreement or each Loan Party has furnished Agent and Lenders with an indemnification satisfactory to Agent and Lenders with respect thereto. Accordingly, each Loan Party waives any rights which it may have under the Uniform Commercial Code 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 Loan Party, 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 (other than Hedge Liabilities and Cash Management Liabilities) have been paid in full in immediately available funds. All representations, warranties, covenants, waivers and agreements contained herein shall survive termination hereof until all Obligations (other than Hedge Liabilities and Cash Management Liabilities) are paid and performed in full.

XIV. REGARDING AGENT.

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

123

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), 3.3(a) and 3.4 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 nonappealable 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. 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.

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 Borrower and each Guarantor 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 Borrower and each Guarantor. 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 Borrower 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 or sufficiency of this Agreement or any Other Document, or of the financial condition of any

124

Borrower or any Guarantor, 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 or prospects 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 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 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, email, facsimile, 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,

125

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 default or misconduct of any such agents or attorneys-in-fact selected by Agent with reasonable care.

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 Revolving Commitment Amount constitutes of the total aggregate Revolving 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 all amounts from time to time due and payable by it for

126

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.

XV. BORROWING AGENCY.

15.1 Borrowing Agency Provisions.

(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 of 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

127

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, GX Mexico shall only be liable for the GX Mexico Obligations.

(c) All Obligations (other than Hedge Liabilities and Cash Management Liabilities) shall be joint and several (provided, that GX Mexico shall only be liable for the GX Mexico Obligations), and each Borrower shall make payment upon the maturity of the Obligations (other than Hedge Liabilities and Cash Management Liabilities) 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 the other Borrowers or any other Person directly or contingently liable for the Obligations hereunder, or against or with respect to any other Borrowers' property (including 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 Hedge Liabilities and Cash Management Liabilities).

15.3 Limitation on Liability of GX Mexico. It is the intent of the parties and the parties hereby agree that, notwithstanding any provision of this Agreement or any Other Documents, (a) GX Mexico shall not be liable for, provide credit support with respect to, pay any costs or expenses or fees or indemnify in any way for any Obligations other than the GX Mexico Obligations, (b) GX Mexico shall not be a Guarantor of any Obligations other than the GX Mexico Obligations, (c) the present and future assets of GX Mexico shall not be subject to any Charges, claim or action by the Agent or the Lenders to satisfy any Obligations other than the GX Mexico Obligations and (d) neither the Agent nor the Lenders shall have any recourse under this Agreement or any Other Documents against GX Mexico or its assets in respect of any Obligations other than the GX Mexico Obligations. In furtherance of the foregoing, each of the parties acknowledges and agrees that the liability of GX Mexico for the payment and performance of its covenants, representations and warranties set forth in this Agreement and the Other Documents shall be several from but not joint with the Obligations of the Borrowers, and the Collateral of GX Mexico shall not secure or be applied in satisfaction, by way of payment, prepayment or otherwise, of all or any portion of the Obligations other than the GX Mexico Obligations. All amounts paid by GX Mexico and all

128

value derived from its assets shall be applied only to the GX Mexico Obligations. Any references in this Agreement or in any Other Documents to specific statutes or to governmental agencies of the United States of America, shall be, when applied to GX Mexico, deemed to include a reference to the applicable, if any, provisions or governmental agencies of Mexico, as the case may be, if any. Any reference in a financial covenant or otherwise to any Dollar figure shall be deemed, when applied to GX Mexico, to refer to the U.S. Dollar Equivalent of the applicable foreign currency.

XVI. MISCELLANEOUS.

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. 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 GX Mexico only, the Agent and Lenders shall not be precluded from initiating any proceeding against it in the courts of the Mexico City, United Mexican States 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. 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 matters involving GX Mexico and Mexican law, Mexico City, United Mexican States. GX Mexico hereby irrevocable designates, appoints and empowers ION Geophysical Corporation, with an office on the Sixth Amendment Effective Date at 2105 CityWest Blvd., Suite 100, Houston, Texas 77042-2839, Attention: General Counsel (the “Process Agent”), in the case of any suit, action or proceeding brought in the United States as its designee appointee and agent to receive for and on its behalf service of any and all legal process summons notices and documents that may be served in any action or proceeding arising out of or in connection with this Agreement or any other related document. Such service may be made by mailing (by registered or certificate mail postage prepaid) or delivering a copy of such to GX Mexico in the care of the Process Agent at the Process Agent's above address and GX Mexico hereby irrevocably authorizes and directs

129

the Process Agent to accept such service on its behalf. As an alternative method of service GX Mexico irrevocably consents to the service of any and all process in any such action or proceeding by the mailing (by registered certified mail postage prepaid) of copies of such process to the Process Agent of GX Mexico at its address. GX Mexico agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdiction by suit on the judgment or in any other manner provided by law.

16.2 Entire Understanding.

(a) This Agreement, the documents executed concurrently herewith and the Other Documents 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 in accordance with this Section 16.2. Notwithstanding the foregoing, Borrowing Agent and 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 each Lender (which copy may be provided by electronic mail) and, if no Lender shall have objected within two Business Days after receipt of such notice, such modification shall be deemed effective. 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 executed by Borrowers, 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:

(i) increase the Revolving Commitment Percentage, or the maximum dollar amount of the Revolving Commitment Amount of any Lender without the consent of such Lender directly affected thereby;

(ii) whether or not any Advances are outstanding, extend the Term or the time for payment of principal or interest of any Advance (excluding the due date of any mandatory prepayment of an Advance), or any fee payable to any Lender, or reduce the principal amount of or the rate of interest borne by any Advances or reduce any fee payable to any Lender, without the consent of each Lender directly affected thereby (except that Required Lenders may

130

elect to waive or rescind any imposition of the Default Rate under Section 3.1 or of default rates of Letter of Credit fees under Section 3.2 (unless imposed by Agent));

(iii) increase the Maximum Revolving Advance Amount without the consent of all Lenders;

(iv) alter the definition of the term Required Lenders or alter, amend or modify this Section 16.2(b) without the consent of all Lenders;

(v) alter, amend or modify the provisions of Section 11.5 without the consent of all Lenders;

(vi) release any Collateral during any calendar year (other than the release of any Collateral in connection with the consummation of any action or transaction by a Borrower permitted hereunder or otherwise in accordance with the provisions of this Agreement) having an aggregate value in excess of $5,000,000 without the consent of all Lenders;

(vii) change the rights and duties of Agent without the consent of all Lenders;

(viii) subject to clause (e) below, permit any Revolving Advance to be made if after giving effect thereto the total of Revolving Advances outstanding hereunder would exceed the Formula Amount for more than sixty (60) consecutive Business Days or exceed one hundred and ten percent (110%) of the Formula Amount without the consent of all Lenders;

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

(x) release any Guarantor or Borrower without the consent of all Lenders.

(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 with respect to any matter requiring the consent of all Lenders 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

131

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 the commitments of Lenders to make Revolving Advances hereunder have been terminated for any reason, or (iii) any other contrary provision of this Agreement, Agent may at its discretion and without the consent of any Lender, voluntarily permit the outstanding Revolving Advances at any time to exceed the Formula Amount at such time (such sum, the “Overadvance Threshold Amount”) by up to ten percent (10%) of the Formula Amount for up to sixty (60) consecutive Business Days (the “Out-of-Formula Loans”). If Agent is willing in its sole and absolute discretion to permit such Out-of-Formula Loans, Lenders holding the Revolving Commitments shall be obligated to fund such Out-of-Formula Loans in accordance with their respective Revolving 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 Revolving 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 (but for greater certainty, not including where the Formula Amount is exceeded as a result of GX Mexico’s Collateral being included in the Formula Amount for advances to the U.S. Borrowers) for any reason, including, but not limited to, Collateral previously deemed to be “Eligible Domestic Receivables”, “Eligible Unbilled Receivables”, “Eligible Foreign Receivables” or “Eligible Inventory”, 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 Revolving 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 this Section 16.2, Agent is hereby authorized by Borrowers and Lenders, at any time in 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 on behalf of

132

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 $10,000,000 in the aggregate and provided further that at any time after giving effect to any such Protective Advances, the outstanding Revolving Advances, Swing Loans and Maximum Undrawn Amount of all outstanding Letters of Credit do not exceed the Maximum Revolving Advance Amount. Lenders holding the Revolving Commitments shall be obligated to fund such Protective Advances and effect a settlement with Agent therefor upon demand of Agent in accordance with their respective Revolving 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 Revolving Commitment under this Agreement and the Other Documents with respect to such Revolving Advances.

16.3 Successors and Assigns; Participations; New Lenders.

(a) This Agreement shall be binding upon and inure to the benefit of Borrowers, Agent, each Lender, all future holders of the Obligations and their respective successors and assigns, except that no Borrower may assign or transfer any of its rights or obligations under this Agreement (including, in each case, by way of an LLC Division) 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 to other Persons so long as any such Person is not an Ineligible Person (each such transferee or purchaser of a participating interest, a “Participant”); provided that any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to approve any amendment, modification or waiver of any provision of this Agreement or any Other Document; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in clauses (i) through (x) of the proviso in Section 16.2(b) that affects such Participant. Each Participant may exercise all rights of payment (including rights of set-off) with respect to the portion of such Advances held by it or other Obligations payable hereunder as fully as if such Participant were the direct holder thereof provided that (i) 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 unless the sale of the participation to such Participant is made with Borrowers' prior written consent, and (ii) 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 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. Any Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of Borrowers, maintain a register on which it enters the name and address

133

of each Participant and the principal amounts (and stated interest) of each Participant's interest in the Advances or other obligations hereunder or any Other Document (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 hereunder or under 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.

(c) Any Lender, with the consent of Agent (unless such assignment is to a Lender or an Affiliate of a Lender) and, unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Permitted Assignee, the consent of Borrowers (such Borrowers' consent not to be unreasonably withheld or delayed, provided that Borrowers shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to Agent within five (5) Business Days after having received prior notice thereof), may sell, assign or transfer all or any part of its rights and obligations under or relating to Revolving Advances under this Agreement and the Other Documents to one or more additional Persons and one or more additional Persons 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, provided, however, that each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender's rights and obligations under this Agreement with respect to each of the Revolving Advances under this Agreement in which such Lender has an interest. 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 Revolving 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 Revolving 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 Revolving 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. Subject to Borrowers' consent rights described above, 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

134

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, acting solely for this purpose as an agent of Borrower, 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 Borrowing Agent 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) Subject to the limitations and conditions set forth in Section 16.15, 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.

(g) Notwithstanding anything to the contrary contained in this Agreement, any Lender may at any time and from time to time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

135

16.4 Application of Payments. 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 the GX Mexico Obligations, as applicable; provided that, for the avoidance of doubt, no Collateral supporting the GX Mexico Obligations or any assets or property of GX Mexico shall be used to satisfy the Obligations of any U.S. Borrower. 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 Borrower 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 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, GX Mexico shall only be liable for any indemnification obligations hereunder to the extent related to the GX Mexico Obligations or attributable to its assets) in arising out of or in any way relating to or as a consequence, direct or indirect, of: (i) this Agreement, the Other Documents, the Advances and other Obligations and/or the transactions contemplated hereby including the Transactions, (ii) 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, (iii) any Borrower's or any Guarantor'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, (iv) the enforcement of any of the rights and remedies of Agent, Issuer or any Lender under the Agreement and the Other Documents, (v) any threatened or actual imposition of fines or penalties, or disgorgement of benefits, for violation of any Anti-Terrorism Law by any Borrower, any Affiliate or Subsidiary of any Borrower, or any Guarantor, and (vi) 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 Agent or any Lender is a party thereto. Without limiting the generality of any of the foregoing, each Borrower shall defend, protect, indemnify, pay and save harmless each Indemnified Party from (x) 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 (y) 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 Materials 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

136

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. Borrowers' obligations under this Section 16.5 shall arise upon the discovery of the presence of any Hazardous Materials 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 Materials, in each such case except to the extent it has been determined by a final non-appealable judgment of a court of competent jurisdiction to have resulted from (1) the gross negligence, bad faith or willful misconduct of the party to be indemnified, (2) any material breach (or, in the case of a proceeding brought by any Borrower, any breach) of this Agreement or any Other Document by the party to be indemnified or (3) disputes, claims, demands, actions, judgments or suits not arising from any act or omission by any Borrower or any of their Affiliates, brought by an Indemnified Party against any other Indemnified Party (other than disputes, claims, demands, actions, judgments or suits involving claims against the Agent in its capacity as such). 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 Materials 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.

16.7 Survival. The obligations of Borrowers under Sections 2.2(f), 2.2(g), 2.2(h), 3.7, 3.8, 3.9, 3.10, 16.5 and 16.9 and the obligations of Lenders under Sections 2.2, 2.15(b), 2.16, 2.18, 2.19, 14.8 and 16.5, shall survive termination of this Agreement and the Other Documents and payment in full of the Obligations.

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.

16.9 Expenses. Borrowers shall pay (i) all reasonable out-of-pocket expenses incurred by Agent and its Affiliates (including the reasonable fees, charges and disbursements of counsel for Agent), and shall pay all fees and time charges and disbursements for attorneys who may be employees of Agent, in connection with the syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and administration of this Agreement and the Other Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by Issuer in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder, (iii) all reasonable out-of-pocket expenses incurred by Agent, any Lender or Issuer (including the reasonable fees, charges and disbursements of any counsel for Agent, any Lender or Issuer), and shall pay all fees and time charges for attorneys who may be employees of Agent, any Lender or Issuer, in connection with the enforcement or protection of its rights (A) in connection with this

139

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; therefor, 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. No Loan Party or Indemnified Party, nor any agent or attorney for any of them, shall be liable to any other Loan Party or Indemnified Party or any agent or attorney for any of them, or any Guarantor (or any Affiliate 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 (provided the foregoing waiver shall not affect Borrowers' obligation to indemnify any Indemnified Party pursuant to Section 16.5 hereof).
