SECTION 2

THE COMMITMENT

2.01 Commitments. Each Lender agrees severally, on and subject to the terms and conditions of this Agreement (including Section 6), to make up to two term loans (provided that PIK Loans shall be deemed not to constitute “term loans” for purposes of this Section 2.01) to Borrower, each on a Business Day during the Commitment Period in Dollars in an aggregate principal amount for such Lender not to exceed such Lender’s Commitment; provided, however, that at no time shall any Lender be obligated to make a Loan in excess of such Lender’s Proportionate Share of the amount by which the then effective Commitments exceeds the aggregate principal amount of Loans outstanding at such time. Amounts of Loans repaid may not be reborrowed.

2.02 Borrowing Procedures. Subject to the terms and conditions of this Agreement (including Section 6), each Borrowing (other than a Borrowing of PIK Loans) shall be made on written notice in the form of Exhibit B given by Borrower to the Lenders not later than 11:00 a.m. (Central time) on the Borrowing Notice Date (a “Notice of Borrowing”).

2.03 Fees. On the first Borrowing Date, Borrower shall pay, out of the proceeds of the Loans advanced by the Lenders on such Borrowing Date, a financing fee in an amount equal to $200,000. Such financing fee shall be paid by the Borrower to the Lenders pro rata in accordance with such Lenders’ Proportionate Shares.

2.04 Notes. If requested by any Lender, the Loans of such Lender shall be evidenced by one or more promissory notes (each a “Note”). Borrower shall prepare, execute and deliver to the Lenders such promissory note(s) payable to the Lenders (or, if requested by the Lenders, to the Lenders and their registered assigns) and in the form attached hereto as Exhibit C-1. Thereafter, the Loans and interest thereon shall at all times (including after assignment pursuant to Section 12.05) be represented by one or more promissory notes in such form payable to the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

2.05 Use of Proceeds. Borrower shall use the proceeds of the Loans for general working capital purposes and corporate purposes and to pay fees, costs and expenses incurred in connection with the Transactions; provided that the Lenders shall have no responsibility as to the use of any proceeds of Loans in the amount made by PIOP. No portion of any proceeds of Loans in the amount made by PIOP (i) will be used to acquire realty or to discharge an obligation relating to the prior acquisition of realty; (ii) will be used outside of the United States (except to pay for services to be rendered outside the United States and to acquire from abroad inventory, material and equipment or property rights for use or sale in the United States, unless prohibited by Part 107.720 of the United States Code of Federal Regulations); or (iii) will be used for any purpose contrary to the public interest (including but not limited to activities which are in violation of law) or inconsistent with free competitive enterprise, in each case, within the meaning of Part 107.720 of Title 13 of the United States Code of Federal Regulations. Borrower will use the proceeds of the Loans in the amount made by PIOP for only those purposes specified in the SBA Form 1031 provided to the Lenders, and Borrower shall not violate any SBA regulations which may be applicable to it.

2.06 Defaulting Lenders.

20

(a) Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(b) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 12.04.

(c) Reallocation of Payments. Any payment of principal, interest, fees or other amounts received by the Lenders for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Section 11 or otherwise), shall be applied at such time or times as follows: first, as Borrower may request (so long as no Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement; second, if so determined by the Majority Lenders and Borrower, to be held in a non-interest bearing deposit account and released in order to satisfy obligations of such Defaulting Lender to fund Loans under this Agreement; third, to the payment of any amounts owing to the Lenders as a result of any judgment of a court of competent jurisdiction obtained by any Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; fourth, so long as no Default exists, to the payment of any amounts owing to Borrower as a result of any judgment of a court of competent jurisdiction obtained by Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and fifth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (A) such payment is a payment of the principal amount of any Loans in respect of which such Defaulting Lender has not fully funded its appropriate share and (B) such Loans were made at a time when the conditions set forth in Section 6 were satisfied or waived, such payment shall be applied solely to pay the Loans of all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of such Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender pursuant to this Section 2.06(c) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(d) Defaulting Lender Cure. If Borrower and the Majority Lenders agree in writing in their sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, that Lender will, to the extent applicable, purchase that portion of outstanding Loans of the other Lenders or take such other actions as necessary to cause the Loans to be held on a pro rata basis by the Lenders in accordance with their Proportionate Share, whereupon that Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

2.07 Substitution of Lenders.

21

(a) Substitution Right. If any Lender (an “Affected Lender”), (i) becomes a Defaulting Lender or (ii) does not consent to any amendment, waiver or consent to any Loan Document for which the consent of the Majority Lenders is obtained but that requires the consent of other Lenders (a “Non-Consenting Lender”), then (x) Borrower may elect to pay in full such Affected Lender with respect to all Obligations due to such Affected Lender or (y) either Borrower or the Majority Lenders shall identify any willing Lender or Affiliate of any Lender or Eligible Transferee (in each case, a “Substitute Lender”) to substitute for such Affected Lender; provided that any substitution of a Non-Consenting Lender shall occur only with the consent of Majority Lenders.

(b) Procedure. To substitute such Affected Lender or pay in full all Obligations owed to such Affected Lender, Borrower shall deliver a notice to such Affected Lender. The effectiveness of such payment or substitution shall be subject to the delivery by Borrower (or, as may be applicable in the case of a substitution, by the Substitute Lender) of (i) payment for the account of such Affected Lender, of, to the extent accrued through, and outstanding on, the effective date for such payment or substitution, all Obligations owing to such Affected Lender (which for the avoidance of doubt, shall not include any Prepayment Premium) and (ii) in the case of a substitution, an Assignment and Acceptance executed by the Substitute Lender, which shall thereunder, among other things, agree to be bound by the terms of the Loan Documents; provided, however, that if the Affected Lender does not execute such Assignment and Acceptance within ten (10) Business Days of delivery of the notice required hereunder, such Affected Lender shall be deemed to have executed such Assignment and Acceptance.

(c) Effectiveness. Upon satisfaction of the conditions set forth in Section 2.07(a) and Section 2.07(b), the Control Agent shall record such substitution or payment in the Register, whereupon (i) in the case of any payment in full of an Affected Lender, such Affected Lender’s Commitments shall be terminated and (ii) in the case of any substitution of an Affected Lender, (A) such Affected Lender shall sell and be relieved of, and the Substitute Lender shall purchase and assume, all rights and claims of such Affected Lender under the Loan Documents, except that the Affected Lender shall retain such rights under the Loan Documents that expressly provide that they survive the repayment of the Obligations and the termination of the Commitments, (B) such Affected Lender shall no longer constitute a “Lender” hereunder and such Substitute Lender shall become a “Lender” hereunder and (C) such Affected Lender shall execute and deliver an Assignment and Acceptance to evidence such substitution; provided, however, that the failure of any Affected Lender to execute any such Assignment and Acceptance shall not render such sale and purchase (or the corresponding assignment) invalid.

SECTION 3

PAYMENTS OF PRINCIPAL AND INTEREST

3.01 Repayment.

(a) Repayment. During the Interest-Only Period, no payments of principal of the Loans shall be due. Borrower agrees to repay to the Lenders the outstanding principal amount of the Loans, on each Payment Date occurring after the Interest-Only Period, in equal installments. The amounts of such installments shall be calculated by dividing (i) the sum of the aggregate

22

any default under the Borrower Lease or permit Lenders to take such other action required to enable Lenders to cure or remedy the matter in default and preserve the security interest of Lenders under the Loan Documents with respect to the Borrower Facility.

(iii) Borrower shall use commercially reasonable efforts to enforce, in a commercially reasonable manner, each covenant or obligation of the Borrower Landlord in the Borrower Lease in accordance with its terms. Subject to the terms and requirements of the Borrower Lease, within ten (10) days after receipt of written request by Lenders, Borrower shall use reasonable efforts to obtain from the Borrower Landlord under the Borrower Lease and furnish to Lenders an estoppel certificate from Borrower Landlord stating the date through which rent has been paid and whether or not, to Borrower Landlord’s knowledge, there are any defaults thereunder and specifying the nature of such claimed defaults, if any, and such other matters as Lenders may reasonably request or in the form required pursuant to the terms of the Borrower Lease. Borrower shall furnish to Lenders all information that Lenders may reasonably request from time to time in the possession of Borrower (or reasonably available to Borrower) concerning the Borrower Lease and Borrower’s compliance with the Borrower Lease.

(iv) Borrower, promptly upon learning that Borrower Landlord has failed to perform the material terms and provisions under the Borrower Lease and immediately upon learning of a rejection or disaffirmance or purported rejection or disaffirmance of the Borrower Lease pursuant to any state or federal bankruptcy law, shall notify Lenders thereof. Borrower shall promptly notify Lenders of any request that any party to the Borrower Lease makes for arbitration or other dispute resolution procedure pursuant to the Borrower Lease and of the institution of any such arbitration or dispute resolution. Borrower hereby authorizes Lenders to attend any such arbitration or dispute, and upon the occurrence and during the continuance of an Event of Default participate in any such arbitration or dispute resolution but such participation shall not be to the exclusion of Borrower; provided, however, that, in any case, Borrower shall consult with Lenders with respect to the matters related thereto. Borrower shall promptly deliver to Lenders a copy of the determination of each such arbitration or dispute resolution mechanism.

(v) If Lenders or their designee shall acquire or obtain a new Borrower Lease following a termination of the Borrower Lease, then Borrower shall have no right, title or interest whatsoever in or to such new Borrower Lease, or any proceeds or income arising from the estate arising under any such new Borrower Lease, including from any sale or other disposition thereof. Lenders or their designee shall hold such new Borrower Lease free and clear of any right or claim of Borrower.

(vi) Borrower shall promptly, after obtaining knowledge of such filing notify Lenders orally of any filing by or against Borrower Landlord under the Borrower Lease of a petition under the Bankruptcy Code or other applicable law. Borrower shall thereafter promptly give written notice of such filing to Lenders, setting forth any information available to Borrower as to the date of such filing, the court in which such petition was filed, and the relief sought in such filing. Borrower shall promptly deliver to Lenders any and all notices, summonses, pleadings, applications and other documents received by Borrower in connection with any such petition and any proceedings relating to such petition.

23

8.09 Licenses. Borrower shall, and shall cause each of its Subsidiaries to, obtain and maintain all licenses, authorizations, consents, filings, exemptions, registrations and other Governmental Approvals necessary in connection with the execution, delivery and performance of the Loan Documents, the consummation of the Transactions or the operation and conduct of its business and ownership of its properties, except where failure to do so could not reasonably be expected to have a Material Adverse Effect.

8.10 Action under Environmental Laws. Borrower shall, and shall cause each of its Subsidiaries to, upon becoming aware of the presence of any Hazardous Materials or the existence of any environmental liability under applicable Environmental Laws with respect to their respective businesses, operations or properties, take all actions, at their cost and expense, as shall be necessary or advisable to investigate and clean up the condition of their respective businesses, operations or properties, including all required removal, containment and remedial actions, and restore their respective businesses, operations or properties to a condition in compliance with applicable Environmental Laws.

8.11 Use of Proceeds. The proceeds of the Loans will be used only as provided in Section 2.05. No part of the proceeds of the Loans will be used, whether directly or indirectly, for any purpose that entails a violation of any of the Regulations of the Board of Governors of the Federal Reserve System, including Regulations T, U and X. Neither Borrower nor any of its affiliates (as that term is defined in Section 121.103 of Title 13 of the United States Code of Federal Regulation) will engage in any activities or use directly or indirectly the proceeds from the Loans for any purpose for which an SBIC is prohibited from providing funds by the SBIC Act as set forth in Section 107.720 of Title 13 of the United States Code of Federal Regulation.

8.12 Certain Obligations Respecting Subsidiaries; Further Assurances.

(a) Subsidiary Guarantors. Borrower will take such action, and will cause each of its Subsidiaries to take such action, from time to time as shall be necessary to ensure that all Subsidiaries that are Domestic Subsidiaries of Borrower (other than Computational Engines, Inc.), and such Foreign Subsidiaries as are required under Section 8.12(b), are “Subsidiary Guarantors” hereunder. Without limiting the generality of the foregoing, in the event that Borrower or any of its Subsidiaries shall form or acquire any new Subsidiary that is a Domestic Subsidiary (other than Computational Engines, Inc.) or a Foreign Subsidiary meeting the requirements of Section 8.12(b), Borrower and its Subsidiaries will promptly and in any event within 30 days of the formation or acquisition of such Subsidiary:

(i) cause such new Subsidiary to become a “Subsidiary Guarantor” hereunder, and a “Grantor” under the Security Agreement, pursuant to a Guarantee Assumption Agreement;

(ii) take such action or cause such Subsidiary to take such action (including delivering such shares of stock together with undated transfer powers executed in blank) as shall be necessary to create and perfect valid and enforceable first priority (subject to Permitted Priority Liens) Liens on substantially all of the personal property of such new Subsidiary as collateral security for the obligations of such new Subsidiary hereunder;

24

(iii) to the extent that the parent of such Subsidiary is not a party to the Security Agreement or has not otherwise pledged Equity Interests in its Subsidiaries in accordance with the terms of the Security Agreement and this Agreement, cause the parent of such Subsidiary to execute and deliver a pledge agreement in favor of the Lenders in respect of all outstanding issued shares of such Subsidiary; and

(iv) deliver such proof of corporate action, incumbency of officers, opinions of counsel and other documents as is consistent with those delivered by each Obligor pursuant to Section 6.01 on the Closing Date or as the Majority Lenders shall have requested.

In the event that, at any time, Foreign Subsidiaries of Borrower have, in the aggregate, (i) total revenues constituting 5% or more of the total revenues of Borrower and its Subsidiaries on a consolidated basis, or (ii) total assets constituting 5% or more of the total assets of Borrower and its Subsidiaries on a consolidated basis, promptly (and, in any event, within 30 days after such time) Borrower shall cause one or more of such Foreign Subsidiaries to become Subsidiary Guarantors in the manner set forth in Section 8.12(a), such that, after such Subsidiaries become Subsidiary Guarantors, the non-guarantor Foreign Subsidiaries in the aggregate shall cease to have revenues or assets, as applicable, that meet the thresholds set forth in clauses (i) and (ii) above; provided that no Foreign Subsidiary shall be required to become a Subsidiary Guarantor if doing so would result in material adverse tax consequences for Borrower and its Subsidiaries, taken as a whole.

(c) Further Assurances. Borrower will, and will cause each of its Subsidiaries to, take such action from time to time as shall reasonably be requested by the Majority Lenders to effectuate the purposes and objectives of this Agreement.

Without limiting the generality of the foregoing, Borrower will, and will cause each Person that is required to be a Subsidiary Guarantor to, take such action from time to time (including executing and delivering such assignments, security agreements, control agreements and other instruments) as shall be reasonably requested by the Majority Lenders to create, in favor of the Lenders, perfected security interests and Liens in substantially all of the personal property of such Obligor (subject to Permitted Liens) as collateral security for the Obligations; provided that any such security interest or Lien shall be subject to the relevant requirements of the Security Documents.

8.13 Termination of Non-Permitted Liens. In the event that Borrower or any of its Subsidiaries shall become aware or be notified by the Lenders of the existence of any outstanding Lien against any Property of Borrower or any of its Subsidiaries, which Lien is not a Permitted Lien, Borrower shall use its best efforts to promptly terminate or cause the termination of such Lien.

8.14 Intellectual Property.

(a) Notwithstanding any provision in this Agreement or any other Loan Documents to the contrary, the Lenders are not assuming any liability or obligation of Borrower, the Subsidiary Guarantors or their Affiliates of whatever nature, whether presently in existence or arising or asserted hereafter. All such liabilities and obligations shall be retained by and remain

25

obligations and liabilities of the Obligors, the Subsidiary Guarantors and/or their Affiliates as the case may be. Without limiting the foregoing, the Lenders are not assuming and shall not be responsible for any liabilities or Claims of Borrower, the Subsidiary Guarantors or their Affiliates, whether present or future, absolute or contingent and whether or not relating to the Obligors, the Obligor Intellectual Property, and/or the Material Agreements, and Borrower shall indemnify and save harmless the Lenders from and against all such liabilities, Claims and Liens.

(b) In the event that the Obligors acquire Obligor Intellectual Property during the term of this Agreement, then the provisions of this Agreement shall automatically apply thereto and any such Obligor Intellectual Property shall automatically constitute part of the Collateral hereunder, without further action by any party, in each case from and after the date of such acquisition (except that any representations or warranties of any Obligor shall apply to any such Obligor Intellectual Property only from and after the date, if any, subsequent to such acquisition that such representations and warranties are brought down or made anew as provided herein).

8.15 Small Business Documentation. Borrower shall accurately complete, execute, and deliver to PIOP prior to the Closing Date, SBA Forms 480, 652, and 1031 (Parts A and B).

8.16 Warrants. If the Required Equity Financing occurs on or prior to March 13, 2014 but the Borrower shall not have made the first Borrowing by such date, Borrower shall promptly, and in any case not later than March 31, 2014, (i) issue to the Lenders all of the Warrants described in Section 6.01(i)(xiv) and (ii) pay to Lenders the financing fee set forth in Section 2.03 as if the initial Borrowing had occurred on such date.

SECTION 12

MISCELLANEOUS

12.01 No Waiver. No failure on the part of the Lenders to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege under any Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under any Loan Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The remedies provided herein are cumulative and not exclusive of any remedies provided by law.

12.02 Notices. All notices, requests, instructions, directions and other communications provided for herein (including any modifications of, or waivers, requests or consents under, this Agreement) shall be given or made in writing (including by telecopy) delivered, if to Borrower,

38

another Obligor or the Lenders, to its address specified on the signature pages hereto or its Guarantee Assumption Agreement, as the case may be, or at such other address as shall be designated by such party in a notice to the other parties. Except as otherwise provided in this Agreement, all such communications shall be deemed to have been duly given upon receipt of a legible copy thereof, in each case given or addressed as aforesaid. All such communications provided for herein by telecopy shall be confirmed in writing promptly after the delivery of such communication (it being understood that non-receipt of written confirmation of such communication shall not invalidate such communication). Notices, documents, certificates and other deliverables to the Lenders by any Obligor may be made solely to the Control Agent and the Control Agent shall promptly deliver such notices, documents, certificates and other deliverables to the other Lenders hereunder.

12.03 Expenses, Indemnification, Etc.

(a) Expenses. Borrower agrees to pay or reimburse (i) the Lenders for all of their reasonable out of pocket costs and expenses (including the reasonable out-of-pocket fees and expenses of Morrison & Foerster LLP, special counsel to the Lenders, and any sales, goods and services or other similar taxes applicable thereto, and printing, reproduction, document delivery, communication and travel costs) in connection with (x) the negotiation, preparation, execution and delivery of this Agreement and the other Loan Documents and the making of the Loans (exclusive of post-closing costs), (y) post-closing costs and (z) the negotiation or preparation of any modification, supplement or waiver of any of the terms of this Agreement or any of the other Loan Documents (whether or not consummated) and (ii) the Lenders for all of their out of pocket costs and expenses (including the fees and expenses of legal counsel) in connection with any enforcement or collection proceedings resulting from the occurrence of an Event of Default; provided, however, that Borrower shall not be required to pay or reimburse any amounts pursuant to Section 12.03(a)(i)(x) in excess of $200,000; provided further that, so long as the Loans are consummated and all Commitments fully drawn prior to the expiry of the Commitment Period, then such fees shall be credited from the fees paid by the Borrower pursuant to Section 2.03.

(b) Indemnification. Borrower hereby indemnifies the Lenders, their Affiliates, and their respective directors, officers, employees, attorneys, agents, advisors and controlling parties (each, an “Indemnified Party”) from and against, and agrees to hold them harmless against, any and all Claims and Losses of any kind (including reasonable fees and disbursements of counsel), joint or several, that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or relating to any investigation, litigation or proceeding or the preparation of any defense with respect thereto arising out of or in connection with or relating to this Agreement or any of the other Loan Documents or the transactions contemplated hereby or thereby or any use made or proposed to be made with the proceeds of the Loans, whether or not such investigation, litigation or proceeding is brought by Borrower, any of its shareholders or creditors, an Indemnified Party or any other Person, or an Indemnified Party is otherwise a party thereto, and whether or not any of the conditions precedent set forth in Section 6 are satisfied or the other transactions contemplated by this Agreement are consummated, except to the extent such Claim or Loss is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct. Any Indemnified Party seeking indemnity hereunder

39

shall give Borrower prompt notice of any claim for which indemnity may be sought. Borrower may assume defense of such claim with its own counsel so long as such counsel is reasonably acceptable to the relevant Indemnified Party or Parties; provided that such Indemnified Party or Parties shall preserve all rights to settle any claims or admit any liability at its sole discretion. Upon such assumption of defense, Borrower shall have no further indemnity obligation to such Indemnified Party or Parties for the cost of defense. Each Indemnified Party shall reasonably cooperate, at Borrower’s expense, with such defense. No Obligor shall assert any claim against any Indemnified Party, on any theory of liability, for consequential, indirect, special or punitive damages arising out of or otherwise relating to this Agreement or any of the other Loan Documents or any of the transactions contemplated hereby or thereby or the actual or proposed use of the proceeds of the Loans. Borrower, its Subsidiaries and Affiliates and their respective directors, officers, employees, attorneys, agents, advisors and controlling parties are each sometimes referred to in this Agreement as a “Borrower Party.” No Lender shall assert any claim against any Borrower Party, on any theory of liability, for consequential, indirect, special or punitive damages arising out of or otherwise relating to this Agreement or any of the other Loan Documents or any of the transactions contemplated hereby or thereby or the actual or proposed use of the proceeds of the Loans.

12.04 Amendments, Etc. Except as otherwise expressly provided in this Agreement, any provision of this Agreement may be modified or supplemented only by an instrument in writing signed by Borrower and the Lenders. Any consent, approval, (including without limitation any approval of or authorization for any amendment to any of the Loan Documents), instruction or other expression of the Lenders under any of the Loan Documents may be obtained by an instrument in writing signed in one or more counterparts by Majority Lenders; provided however, that the consent of all of the Lenders shall be required to:

(i) amend, modify, discharge, terminate or waive any of the terms of this Agreement if such amendment, modification, discharge, termination or waiver would increase the amount of the Loans, reduce the fees payable hereunder, reduce interest rates or other amounts payable with respect to the Loans, extend any date fixed for payment of principal, interest or other amounts payable relating to the Loans or extend the repayment dates of the Loans;

(ii) amend the provisions of Section 6;

(iii) amend, modify, discharge, terminate or waive any Security Document if the effect is to release a material part of the Collateral subject thereto otherwise than pursuant to the terms hereof or thereof; or

(iv) amend this Section 12.04.

Notwithstanding anything to the contrary herein, a Defaulting Lender shall not have any right to approve or disapprove any amendment, waiver or consent hereunder (and any amendment, waiver or consent which by its terms requires the consent of all Lenders or each affected Lender may be effected with the consent of the applicable Lenders other than Defaulting Lenders), except that (x) the Commitment of any Defaulting Lender may not be increased or extended without the consent of such Lender and (y) any waiver, amendment or modification requiring the

40

consent of all Lenders or each affected Lender that by its terms affects any Defaulting Lender more adversely than other affected Lenders shall require the consent of such Defaulting Lender.

12.05 Successors and Assigns.

(a) General. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Lenders. Any of the Lenders may assign or otherwise transfer any of their rights or obligations hereunder to an assignee in accordance with the provisions of Section 12.05(b), (ii) by way of participation in accordance with the provisions of Section 12.05(e) or (iii) by way of pledge or assignment of a security interest subject to the restrictions of Section 12.05(f). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in Section 12.05(d) and, to the extent expressly contemplated hereby, the Indemnified Parties) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any of the Lenders may at any time assign to one or more Eligible Transferees (or, if an Event of Default has occurred and is continuing, to any Person) all or a portion of their rights and obligations under this Agreement (including all or a portion of the Commitment and the Loans at the time owing to it); provided, however, that no such assignment shall be made to Borrower, an Affiliate of Borrower, or any employees or directors of Borrower at any time or to any party that the assigning Lender should, in the exercise of reasonable diligence, know or that Borrower has notified the assigning Lender is a competitor of Borrower or any Affiliate of any such competitor. Subject to the recording thereof by the Lenders pursuant to Section 12.05(c), from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of the Lenders under this Agreement, and correspondingly the assigning Lender shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of a Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Section 5 and Section 12.03. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.05(b) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.05(e).

(c) Amendments to Loan Documents. Each of the Lenders and the Obligors agrees to enter into such amendments to the Loan Documents, and such additional Security Documents and other instruments and agreements, in each case in form and substance reasonably acceptable to the Lenders and the Obligors, as shall reasonably be necessary to implement and give effect to any assignment made under this Section 12.05.

(d) Register. Lenders, acting solely for this purpose as an agent of Borrower, shall maintain at one of its offices, which shall be the office of the Control Agent, a register for the

41

recordation of the name and address of any assignee of the Lenders and the Commitment and outstanding principal amount of the Loans owing thereto (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and Borrower shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as the “Lender” hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by Borrower, at any reasonable time and from time to time upon reasonable prior notice.

(e) Participations. Any of the Lenders may at any time, without the consent of, or notice to, Borrower, sell participations to any Person (other than a natural person or Borrower or any of Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of the Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) Borrower shall continue to deal solely and directly with the Lenders in connection therewith.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; 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 that would (i) increase or extend the term of such Lender’s Commitment, (ii) extend the date fixed for the payment of principal of or interest on the Loans or any portion of any fee hereunder payable to the Participant, (iii) reduce the amount of any such payment of principal, or (iv) reduce the rate at which interest is payable thereon to a level below the rate at which the Participant is entitled to receive such interest. Subject to Section 12.05(e), Borrower agrees that each Participant shall be entitled to the benefits of Section 5 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.05(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 4.04(a) as though it were the Lender.

(f) Limitations on Rights of Participants. A Participant shall not be entitled to receive any greater payment under Section 5.01 or 5.05 than a Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with Borrower’s prior written consent.

(g) Certain Pledges. The Lenders may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement and any other Loan Document to secure obligations of the Lenders, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release the Lenders from any of their obligations hereunder or substitute any such pledgee or assignee for the Lenders as a party hereto.

12.06 Survival. The obligations of Borrower under Sections 5.01, 5.03, 5.05, 12.03, 12.05, 12.09, 12.10, 12.11, 12.12, 12.13, 12.14 and Section 13 (solely to the extent guaranteeing any of the obligations under the foregoing Sections) shall survive the repayment of the Loans and the termination of the Commitment and, in the case of the Lenders’ assignment of any interest in the

42

Commitment or the Loans hereunder, shall survive, in the case of any event or circumstance that occurred prior to the effective date of such assignment, the making of such assignment, notwithstanding that the Lenders may cease to be “Lenders” hereunder. In addition, each representation and warranty made, or deemed to be made by a notice of the Loans, herein or pursuant hereto shall survive the making of such representation and warranty.

12.08 Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the parties hereto may execute this Agreement by signing any such counterpart.

12.09 Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be governed by, and construed in accordance with, the law of the State of New York, without regard to principles of conflicts of laws that would result in the application of the laws of any other jurisdiction; provided that Section 5-1401 of the New York General Obligations Law shall apply.

12.10 Jurisdiction, Service of Process and Venue.

(a) Submission to Jurisdiction. Each Obligor agrees that any suit, action or proceeding with respect to this Agreement or any other Loan Document to which it is a party or any judgment entered by any court in respect thereof may be brought initially in the federal or state courts in Houston, Texas or in the courts of its own corporate domicile and irrevocably submits to the non-exclusive jurisdiction of each such court for the purpose of any such suit, action, proceeding or judgment. This Section 12.10(a) is for the benefit of the Lenders only and, as a result, no Lender shall be prevented from taking proceedings in any other courts with jurisdiction. To the extent allowed by applicable Laws, the Lenders may take concurrent proceedings in any number of jurisdictions.

(b) Alternative Process. Nothing herein shall in any way be deemed to limit the ability of the Lenders to serve any such process or summonses in any other manner permitted by applicable law.

(c) Waiver of Venue, Etc. Each Obligor irrevocably waives to the fullest extent permitted by law any objection that it may now or hereafter have to the laying of the venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document and hereby further irrevocably waives to the fullest extent permitted by law any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. A final judgment (in respect of which time for all appeals has elapsed) in any such suit, action or proceeding shall be conclusive and may be enforced in any court to the jurisdiction of which such Obligor is or may be subject, by suit upon judgment.

12.11 Waiver of Jury Trial. EACH OBLIGOR AND EACH LENDER HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY SUIT, ACTION OR

43

PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

12.12 Waiver of Immunity. To the extent that any Obligor may be or become entitled to claim for itself or its Property or revenues any immunity on the ground of sovereignty or the like from suit, court jurisdiction, attachment prior to judgment, attachment in aid of execution of a judgment or execution of a judgment, and to the extent that in any such jurisdiction there may be attributed such an immunity (whether or not claimed), such Obligor hereby irrevocably agrees not to claim and hereby irrevocably waives such immunity with respect to its obligations under this Agreement and the other Loan Documents.

12.13 Entire Agreement. This Agreement and the other Loan Documents constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. EACH OBLIGOR ACKNOWLEDGES, REPRESENTS AND WARRANTS THAT IN DECIDING TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS OR IN TAKING OR NOT TAKING ANY ACTION HEREUNDER OR THEREUNDER, IT HAS NOT RELIED, AND WILL NOT RELY, ON ANY STATEMENT, REPRESENTATION, WARRANTY, COVENANT, AGREEMENT OR UNDERSTANDING, WHETHER WRITTEN OR ORAL, OF OR WITH THE LENDERS OTHER THAN THOSE EXPRESSLY SET FORTH IN THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

12.14 Severability. If any provision hereof is found by a court to be invalid or unenforceable, to the fullest extent permitted by applicable law the parties agree that such invalidity or unenforceability shall not impair the validity or enforceability of any other provision hereof.

12.15 No Fiduciary Relationship. Borrower acknowledges that the Lenders have no fiduciary relationship with, or fiduciary duty to, Borrower arising out of or in connection with this Agreement or the other Loan Documents, and the relationship between the Lenders and Borrower is solely that of creditor and debtor. This Agreement and the other Loan Documents do not create a joint venture among the parties.

12.16 Confidentiality. The Lenders agree to maintain the confidentiality of the Confidential Information (as defined in the Non-Disclosure Agreement (defined below)) in accordance with the terms of that certain non-disclosure agreement dated June 5, 2013 between Borrower and Capital Royalty L.P (the “Non-Disclosure Agreement”).

Any new Lender that becomes party to this Agreement hereby agrees to be bound by the terms of the Non-Disclosure Agreement. The parties to this Agreement shall prepare a mutually agreeable press release announcing the completion of this transaction on the Closing Date.

12.17 USA PATRIOT Act. The Lenders hereby notify Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), they are required to obtain, verify and record information that identifies

44

Borrower, which information includes the name and address of Borrower and other information that will allow such Lender to identify Borrower in accordance with the Act.

12.18 Maximum Rate of Interest. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (in each case, the “Maximum Rate”). If the Lenders shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans, and not to the payment of interest, or, if the excessive interest exceeds such unpaid principal, the amount exceeding the unpaid balance shall be refunded to the applicable Obligor. In determining whether the interest contracted for, charged, or received by the Lenders exceeds the Maximum Rate, the Lenders may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Indebtedness and other obligations of any Obligor hereunder, or (d) allocate interest between portions of such Indebtedness and other obligations under the Loan Documents to the end that no such portion shall bear interest at a rate greater than that permitted by applicable Law.

12.19 Real Property Security Waivers.

(a) Real Property Security Waivers.

(i) Each Obligor acknowledges that all or any portion of the Obligations may now or hereafter be secured by a Lien or Liens upon real property evidenced by certain documents including, without limitation, deeds of trust and assignments of rents. Lenders may, pursuant to the terms of said real property security documents and applicable law, foreclose under all or any portion of one or more of said Liens by means of judicial or nonjudicial sale or sales. Each Obligor agrees that Lenders may exercise whatever rights and remedies they may have with respect to said real property security, all without affecting the liability of any Obligor under the Loan Documents hereunder, except to the extent Lenders realize payment by such action or proceeding. No election to proceed in one form of action or against any party, or on any obligation shall constitute a waiver of Lenders’ rights to proceed in any other form of action or against any Obligor or any other Person, or diminish the liability of any Obligor, or affect the right of Lenders to proceed against any Obligor for any deficiency, except to the extent Lenders realize payment by such action, notwithstanding the effect of such action upon any Obligor’s rights of subrogation, reimbursement or indemnity, if any, against Obligor or any other Person.

(ii) To the extent permitted under applicable law, each Obligor hereby waives any rights and defenses that are or may become available to such Obligor by reason of Sections 2787 to 2855, inclusive, of the California Civil Code.

(iii) To the extent permitted under applicable law, each Obligor hereby waives all rights and defenses that such Obligor may have because the Obligations are or may be secured by real property. This means, among other things:

45

(A) Lenders may collect from any Obligor without first foreclosing on any real or personal property collateral pledged by any other Obligor;

(B) If Lenders foreclose on any real property collateral pledged by any Obligor:

(1) The amount of the Loans may be reduced only by the price for which that collateral is sold at the foreclosure sale, even if the collateral is worth more than the sale price; and

(2) Lenders may collect from each Obligor even if Lenders, by foreclosing on the real property collateral, have destroyed any right that such Obligor may have to collect from any other Obligor.

(3) To the extent permitted under applicable law, this is an unconditional and irrevocable waiver of any rights and defenses each Obligor may have because the Obligations hereunder are or may be secured by real property. These rights and defenses include, but are not limited to, any rights or defenses based upon Section 580a, 580b, 580d or 726 of the California Code of Civil Procedure.

(iv) To the extent permitted under applicable law, each Obligor waives all rights and defenses arising out of an election of remedies by Lenders, even though that election of remedies, such as a nonjudicial foreclosure with respect to security for a guaranteed obligation, has destroyed such Obligor’s rights of subrogation and reimbursement against the principal by the operation of Section 580d of the California Code of Civil Procedure or otherwise.

(b) Waiver of Marshaling. WITHOUT LIMITING THE FOREGOING IN ANY WAY, EACH OBLIGOR HEREBY IRREVOCABLY WAIVES AND RELEASES, TO THE EXTENT PERMITTED BY LAW, ANY AND ALL RIGHTS IT MAY HAVE AT ANY TIME (WHETHER ARISING DIRECTLY OR INDIRECTLY, BY OPERATION OF LAW, CONTRACT OR OTHERWISE) TO REQUIRE THE MARSHALING OF ANY ASSETS OF ANY OBLIGOR, WHICH RIGHT OF MARSHALING MIGHT OTHERWISE ARISE FROM ANY PAYMENTS MADE OR OBLIGATIONS PERFORMED.

SECTION 13

GUARANTEE

13.01 The Guarantee. The Subsidiary Guarantors hereby jointly and severally guarantee to the Lenders and their successors and assigns the prompt payment in full when due (whether at stated maturity, by acceleration or otherwise) of the principal of and interest on the Loans and all fees and other amounts from time to time owing to the Lenders by Borrower under this Agreement or under any other Loan Document and by any other Obligor under any of the Loan Documents, in each case strictly in accordance with the terms thereof (such obligations being herein collectively called the “Guaranteed Obligations”). The Subsidiary Guarantors hereby further jointly and severally agree that if Borrower shall fail to pay in full when due (whether at stated maturity, by acceleration or otherwise) any of the Guaranteed Obligations, the Subsidiary Guarantors will promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Guaranteed Obligations,

46

the same will be promptly paid in full when due (whether at extended maturity, by acceleration or otherwise) in accordance with the terms of such extension or renewal.

13.02 Obligations Unconditional. The obligations of the Subsidiary Guarantors under Section 13.01 are absolute and unconditional, joint and several, irrespective of the value, genuineness, validity, regularity or enforceability of the obligations of Borrower under this Agreement or any other agreement or instrument referred to herein, or any substitution, release or exchange of any other guarantee of or security for any of the Guaranteed Obligations, and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, it being the intent of this Section 13.02 that the obligations of the Subsidiary Guarantors hereunder shall be absolute and unconditional, joint and several, under any and all circumstances. Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not alter or impair the liability of the Subsidiary Guarantors hereunder, which shall remain absolute and unconditional as described above:

(a) at any time or from time to time, without notice to the Subsidiary Guarantors, the time for any performance of or compliance with any of the Guaranteed Obligations shall be extended, or such performance or compliance shall be waived;

(b) any of the acts mentioned in any of the provisions of this Agreement or any other agreement or instrument referred to herein shall be done or omitted;

(c) the maturity of any of the Guaranteed Obligations shall be accelerated, or any of the Guaranteed Obligations shall be modified, supplemented or amended in any respect, or any right under this Agreement or any other agreement or instrument referred to herein shall be waived or any other guarantee of any of the Guaranteed Obligations or any security therefor shall be released or exchanged in whole or in part or otherwise dealt with; or

(d) any lien or security interest granted to, or in favor of, the Lenders as security for any of the Guaranteed Obligations shall fail to be perfected.

The Subsidiary Guarantors hereby expressly waive diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that the Lenders exhaust any right, power or remedy or proceed against Borrower under this Agreement or any other agreement or instrument referred to herein, or against any other Person under any other guarantee of, or security for, any of the Guaranteed Obligations.

13.03 Reinstatement. The obligations of the Subsidiary Guarantors under this Section 13 shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of Borrower in respect of the Guaranteed Obligations is rescinded or must be otherwise restored by any holder of any of the Guaranteed Obligations, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, and the Subsidiary Guarantors jointly and severally agree that they will indemnify the Lenders on demand for all reasonable costs and expenses (including fees of counsel) incurred by the Lenders in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim

47

alleging that such payment constituted a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law.

13.04 Subrogation. The Subsidiary Guarantors hereby jointly and severally agree that until the payment and satisfaction in full of all Guaranteed Obligations (other than Warrant Obligations) and the expiration and termination of the Commitment of the Lenders under this Agreement they shall not exercise any right or remedy arising by reason of any performance by them of their guarantee in Section 13.01, whether by subrogation or otherwise, against Borrower or any other guarantor of any of the Guaranteed Obligations or any security for any of the Guaranteed Obligations.

13.05 Remedies. The Subsidiary Guarantors jointly and severally agree that, as between the Subsidiary Guarantors and the Lenders, the obligations of Borrower under this Agreement and under the other Loan Documents may be declared to be forthwith due and payable as provided in Section 11 (and shall be deemed to have become automatically due and payable in the circumstances provided in Section 11) for purposes of Section 13.01 notwithstanding any stay, injunction or other prohibition preventing such declaration (or such obligations from becoming automatically due and payable) as against Borrower and that, in the event of such declaration (or such obligations being deemed to have become automatically due and payable), such obligations (whether or not due and payable by Borrower) shall forthwith become due and payable by the Subsidiary Guarantors for purposes of Section 13.01.

13.06 Instrument for the Payment of Money. Each Subsidiary Guarantor hereby acknowledges that the guarantee in this Section 13 constitutes an instrument for the payment of money, and consents and agrees that the Lender, at its sole option, in the event of a dispute by such Subsidiary Guarantor in the payment of any moneys due hereunder, shall have the right to proceed by motion for summary judgment in lieu of complaint pursuant to N.Y. Civ. Prac. L&R § 3213.

13.07 Continuing Guarantee. The guarantee in this Section 13 is a continuing guarantee, and shall apply to all Guaranteed Obligations whenever arising.

13.08 Rights of Contribution. The Subsidiary Guarantors hereby agree, as between themselves, that if any Subsidiary Guarantor shall become an Excess Funding Guarantor (as defined below) by reason of the payment by such Subsidiary Guarantor of any Guaranteed Obligations, each other Subsidiary Guarantor shall, on demand of such Excess Funding Guarantor (but subject to the next sentence), pay to such Excess Funding Guarantor an amount equal to such Subsidiary Guarantor’s Pro rata Share (as defined below and determined, for this purpose, without reference to the properties, debts and liabilities of such Excess Funding Guarantor) of the Excess Payment (as defined below) in respect of such Guaranteed Obligations. The payment obligation of a Subsidiary Guarantor to any Excess Funding Guarantor under this Section 13.08 shall be subordinate and subject in right of payment to the prior payment in full of the obligations of such Subsidiary Guarantor under the other provisions of this Section 13 and such Excess Funding Guarantor shall not exercise any right or remedy with respect to such excess until payment and satisfaction in full of all of such obligations.

48

For purposes of this Section 13.08, (i) “Excess Funding Guarantor” means, in respect of any Guaranteed Obligations, a Subsidiary Guarantor that has paid an amount in excess of its Pro rata Share of such Guaranteed Obligations, (ii) “Excess Payment” means, in respect of any Guaranteed Obligations, the amount paid by an Excess Funding Guarantor in excess of its Pro rata Share of such Guaranteed Obligations and (iii) “Pro Rata Share” means, for any Subsidiary Guarantor, the ratio (expressed as a percentage) of (x) the amount by which the aggregate present fair saleable value of all properties of such Subsidiary Guarantor (excluding any shares of stock of any other Subsidiary Guarantor) exceeds the amount of all the debts and liabilities of such Subsidiary Guarantor (including contingent, subordinated, unmatured and unliquidated liabilities, but excluding the obligations of such Subsidiary Guarantor hereunder and any obligations of any other Subsidiary Guarantor that have been Guaranteed by such Subsidiary Guarantor) to (y) the amount by which the aggregate fair saleable value of all properties of all of the Subsidiary Guarantors exceeds the amount of all the debts and liabilities (including contingent, subordinated, unmatured and unliquidated liabilities, but excluding the obligations of Borrower and the Subsidiary Guarantors hereunder and under the other Loan Documents) of all of the Subsidiary Guarantors, determined (A) with respect to any Subsidiary Guarantor that is a party hereto on the Closing Date, as of the Closing Date, and (B) with respect to any other Subsidiary Guarantor, as of the date such Subsidiary Guarantor becomes a Subsidiary Guarantor hereunder.

13.09 General Limitation on Guarantee Obligations. In any action or proceeding involving any provincial, territorial or state corporate law, or any state or federal bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Subsidiary Guarantor under Section 13.01 would otherwise, taking into account the provisions of Section 13.08, be held or determined to be void, invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability under Section 13.01, then, notwithstanding any other provision hereof to the contrary, the amount of such liability shall, without any further action by such Subsidiary Guarantor, the Lenders or any other Person, be automatically limited and reduced to the highest amount that is valid and enforceable and not subordinated to the claims of other creditors as determined in such action or proceeding.

13.10 Additional Waivers.

(a) To the extent permitted under applicable law, each Subsidiary Guarantor hereby waives any rights and defenses that are or may become available to Subsidiary Guarantor by reason of Sections 2787 to 2855, inclusive, of the California Civil Code.

(b) To the extent permitted under applicable law, each Subsidiary Guarantor hereby waives all rights and defenses that Subsidiary Guarantor may have because the Obligations are or may be secured by real property. This means, among other things:

(i) Lenders may collect from any Subsidiary Guarantor without first foreclosing on any real or personal property collateral pledged by Borrower;

(ii) If Lenders foreclose on any real property collateral pledged by Borrower:

49

(B) Lenders may collect from each Subsidiary Guarantor even if Lenders, by foreclosing on the real property collateral, has destroyed any right such Subsidiary Guarantor may have to collect from Borrower.

To the extent permitted under applicable law, this is an unconditional and irrevocable waiver of any rights and defenses each Subsidiary Guarantor may have because the Obligations are or may be secured by real property. These rights and defenses include, but are not limited to, any rights or defenses based upon Section 580a, 580b, 580d or 726 of the California Code of Civil Procedure.

(c) To the extent permitted under applicable law, each Subsidiary Guarantor waives all rights and defenses arising out of an election of remedies by Lenders, even though that election of remedies, such as a nonjudicial foreclosure with respect to security for a guaranteed obligation, has destroyed such Subsidiary Guarantor’s rights of subrogation and reimbursement against the principal by the operation of Section 580d of the California Code of Civil Procedure or otherwise.

(d) To the extent permitted under applicable law, each Subsidiary Guarantor hereby waives any right or defense it may have at law or equity, including California Code of Civil Procedure Section 580a, to a fair market value hearing or action to determine a deficiency judgment after a foreclosure.

In furtherance of the foregoing, [Subordinated Lender] hereby appoints Lenders as its attorney-in-fact, with full

3

authority in the place and stead of [Subordinated Lender] and full power of substitution and in the name of [Subordinated Lender] or otherwise, to execute and deliver any document or instrument which [Subordinated Lender] is required to deliver pursuant to this Section 6, such appointment being coupled with an interest and irrevocable. [Subordinated Lender] agrees that Lenders may release or refrain from enforcing its security interest in any Collateral, or permit the use or consumption of such Collateral by Borrower free of any [Subordinated Lender] security interest, without incurring any liability to [Subordinated Lender].

7. Attorney-In-Fact. Until the Senior Discharge Date, [Subordinated Lender] irrevocably appoints Lenders as its attorney-in-fact, with power of attorney with power of substitution, in [Subordinated Lender]’s name or in Lenders’ name, for Lenders’ use and benefit without notice to [Subordinated Lender], to do the following in any bankruptcy, insolvency or similar proceeding involving Borrower:

(a) file any claims for the Subordinated Debt on behalf of [Subordinated Lender] if [Subordinated Lender] does not do so at least 30 days before the time to file claims expires, and

(b) accept or reject any plan of reorganization or arrangement for [Subordinated Lender] and vote [Subordinated Lender]’s claims in respect of the Subordinated Debt in any way it chooses.

Such power of attorney is irrevocable and coupled with an interest.

8. Legend; Amendment of Debt. (a) [Subordinated Lender] will immediately put a legend on the [Subordinated Lender] Note that the [Subordinated Lender] Note is subject to this Agreement.

(b) No amendment of the Subordinated Debt documents will modify this Agreement in any way that terminates or impairs the subordination of the Subordinated Debt or the subordination of any security interest or lien that Lenders have in Borrower’s property. No amendment, modification or waiver of any provision of the Subordinated Debt Documents (including any refinancing thereof) shall be made without first obtaining the consent of Lenders, if the effect thereof is to: (i) increase the interest rate on the Subordinated Debt or change (to earlier dates) the dates upon which principal, interest and other sums are due under the [Subordinated Lender] Note; (ii) alter the redemption, prepayment or subordination provisions thereof; (iii) impose on Borrower or any guarantor of the Subordinated Debt any new or additional prepayment charges, premiums, reimbursement obligations, reimbursable costs or expenses, fees or other payment obligations; (iv) alter the representations, warranties, covenants, events of default, remedies and other provisions in a manner which would make such provisions materially more onerous, restrictive or burdensome to Borrower or any guarantor of the Subordinated Debt; or (v) otherwise increase the obligations of Borrower or any guarantor of the Subordinated Debt in respect of the Subordinated Debt or confer additional rights upon [Subordinated Lender], which individually or in the aggregate would be materially adverse to Borrower or any guarantor of the Subordinated Debt or Lenders.

(c) At any time without notice to [Subordinated Lender], Lenders may take such action with respect to the Senior Debt as Lenders, in their sole discretion, may deem appropriate,

4

including, without limitation, terminating advances, increasing the principal, extending the time of payment, increasing interest rates, renewing, compromising or otherwise amending any documents affecting the Senior Debt and any Collateral securing the Senior Debt, and enforcing or failing to enforce any rights against Borrower or any other person. No action or inaction will impair or otherwise affect Lenders’ rights under this Agreement.

9. Representations and Warranties. [Subordinated Lender] represents and warrants to Lenders that:

(a) all action on the part of [Subordinated Lender], its officers, directors, partners, members and shareholders, as applicable, necessary for the authorization of this Agreement and the performance of all obligations of [Subordinated Lender] hereunder has been taken;

(b) this Agreement constitutes the legal, valid and binding obligation of [Subordinated Lender], enforceable against [Subordinated Lender] in accordance with its terms;

(c) the execution, delivery and performance of and compliance with this Agreement by [Subordinated Lender] will not (i) result in any material violation or default of any term of any of [Subordinated Lender]’s charter, formation or other organizational documents (such as Articles or Certificate of Incorporation, bylaws, partnership agreement, operating agreement, etc.) or (ii) violate any material applicable law, rule or regulation.

10. Term; Reinstatement. This Agreement shall remain effective until the Senior Discharge Date. If, after the Senior Discharge Date, Lenders must disgorge any payments made on the Senior Debt for any reason (including, without limitation, the bankruptcy of Borrower), this Agreement and the relative rights and priorities provided in it, will be reinstated as to all disgorged payments as though the payments had not been made, and [Subordinated Lender] will immediately pay Lenders all payments received under the Subordinated Debt to the extent the payments or retention thereof would have been prohibited under this Agreement.

11. Successors and Assigns. This Agreement binds [Subordinated Lender], its successors or assigns, and benefits Lenders’ successors or assigns. This Agreement is for [Subordinated Lender]’s and Lenders’ benefit and not for the benefit of Borrower or any other party. [Subordinated Lender] shall not sell, assign, pledge, dispose of or otherwise transfer all or any portion of the Subordinated Debt or any related document or any interest in any Collateral therefor unless prior to the consummation of any such action, the transferee thereof shall execute and deliver to Lenders an agreement of such transferee to be bound hereby, or an agreement substantially identical to this Agreement providing for the continued subjection of the Subordinated Debt, the interests of the transferee in the Collateral and the remedies of the transferee with respect thereto as provided herein with respect to [Subordinated Lender] and for the continued effectiveness of all of the other rights of Lenders arising under this Agreement, in each case in form satisfactory to Lenders.

12. Further Assurances. [Subordinated Lender] hereby agrees to execute such documents and/or take such further action as Lenders may at any time or times reasonably request in order to carry out the provisions and intent of this Agreement, including, without limitation,

5

ratifications and confirmations of this Agreement from time to time hereafter, as and when requested by Lenders.

13. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument.

14. Governing Law; Waiver of Jury Trial. (a) This Agreement and the rights and obligations of the parties hereunder shall be governed by, and construed in accordance with, the law of the State of New York, without regard to principles of conflicts of laws that would result in the application of the laws of any other jurisdiction; provided that Section 5-1401 of the New York General Obligations Law shall apply.

(b) EACH PARTY HERETO WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN.

15. Entire Agreement. This Agreement represents the entire agreement with respect to the subject matter hereof, and supersedes all prior negotiations, agreements and commitments. Lenders and [Subordinated Lender] are not relying on any representations by the other creditor party or Borrower in entering into this Agreement, and each of Lenders and [Subordinated Lender] has kept and will continue to keep itself fully apprised of the financial and other condition of Borrower. This Agreement may be amended only by written instrument signed by Lenders and [Subordinated Lender].

16. Legal Fees. In the event of any legal action to enforce the rights of a party under this Agreement, the party prevailing in such action shall be entitled, in addition to such other relief as may be granted, all reasonable costs and expenses, including reasonable attorneys’ fees, incurred in such action.

17. Severability. Any provision of this Agreement which is illegal, invalid, prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent such illegality, invalidity, prohibition or unenforceability without invalidating or impairing the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

18. Notices. All notices, demands, instructions and other communications required or permitted to be given to or made upon any party hereto shall be in writing and shall be delivered or sent by first-class mail, postage prepaid, or by overnight courier or messenger service or by facsimile or electronic mail, message confirmed, and shall be deemed to be effective for purposes of this Agreement on the day that delivery is made or refused. Unless otherwise specified in a notice mailed or delivered in accordance with the foregoing sentence, notices, demands, instructions and other communications in writing shall be given to or made upon the respective parties hereto at their respective addresses and facsimile numbers indicated on the signature pages hereto.

19. Loan Document. Notwithstanding anything to the contrary in the Senior Term Loan Agreement, the parties agree that this Agreement shall be a “Loan Document” under the Senior Term Loan Agreement.

4

(iii) acknowledges, agrees and covenants, notwithstanding Section 2(c), that it shall not contest, challenge or dispute the validity, attachment, perfection, priority or enforceability of the other Creditor’s security interest in the Common Collateral, or the validity, priority or enforceability of the other Creditor’s Claim.

4. Subordination of Remedies. Each Creditor (for purposes of this Section 4, the “Junior Creditor”) agrees that, (i) unless and until all Claims of the other Creditor (for purposes of this Section 4, the “Senior Creditor”) have been indefeasibly paid in full and all commitments of the Senior Creditor under its Credit Documents have been terminated, or (ii) until the expiration of a period of 180 days from the date of notice of default under the Senior Creditor’s Credit Documents given by the Senior Creditor to the Junior Creditor, whichever is earlier, and whether or not any Insolvency Proceeding has been commenced by or against Borrower, the Junior Creditor shall not, without the prior written consent of the Senior Creditor, enforce, or attempt to enforce, any rights or remedies under or with respect to any of such Junior Creditor’s Junior Collateral, including causing or compelling the pledge or delivery of Junior Collateral, any attachment of, levy upon, execution against, foreclosure upon or the taking of other action against or institution of other proceedings with respect to any Junior Collateral, notifying any account debtors of Borrower, asserting any claim or interest in any insurance with respect to the Junior Collateral, or exercising any rights under any lockbox agreement, account control

5. Insolvency Proceedings. In the event of Borrower’s insolvency, reorganization or any case or proceeding under any bankruptcy or insolvency law or laws relating to the relief of debtors, including, without limitation, any voluntary or involuntary bankruptcy, insolvency, receivership or other similar statutory or common law proceeding or arrangement involving Borrower, the readjustment of its liabilities, any assignment for the benefit of its creditors or any marshalling of its assets or liabilities (each, an “Insolvency Proceeding”), (a) this Agreement shall remain in full force and effect in accordance with Section 510(a) of the United States Bankruptcy Code, (b) the Collateral shall include, without limitation, all Collateral arising during or after any such Insolvency Proceeding.

6. Limitation on Liens. Each Creditor agrees that it shall not obtain a security interest on any property of any Obligor to secure all or any portion of such Creditor’s Claims unless, concurrently therewith, the other Creditor obtains a security interest on such property and the Creditors agree that all such security interests are and shall be subject to this Agreement.

7. Notice of Default. Each Creditor shall give to the other prompt written notice of the occurrence of any default or event of default (which has not been promptly waived or cured) under any of such Creditor’s Credit Documents (and any subsequent cure or waiver thereof) and shall, simultaneously with giving any notice of default or acceleration to Borrower, provide to the other Creditor a copy of such notice of default. CR acknowledges and agrees that any event of default under the CR Documents shall be deemed to be an event of default under the [ ] Documents, and [ ] acknowledges and agrees that any event of default under the [ ] Documents shall be deemed to be an event of default under the CR Documents.

8. Release of Liens. In the event of any private or public sale or other disposition, by or with the consent of any Creditor (for purposes of this Section 8, the “Senior Creditor”), of all or any portion of such Creditor’s Senior Collateral, the other Creditor (for purposes of this Section 8, the “Junior Creditor”) agrees that such sale or disposition shall be free and clear of such Junior Creditor’s liens, provided that such sale or disposition is made in accordance with the UCC. The Junior Creditor agrees that, in connection with any such sale or other disposition, (i) the Senior Creditor is authorized to file any and all UCC and other applicable lien releases and/or terminations in respect of the liens held by the Junior Creditor in connection with such a sale or other disposition, and (ii) it shall execute any and all lien releases or other documents reasonably requested by the Senior Creditor in connection therewith.

9. Agent for Perfection.

6

(a) [ ] acknowledges that applicable provisions of the UCC may require, in order to properly perfect CR’s security interest in the Common Collateral securing the CR Claims, that CR possess certain of such Common Collateral, and may require the execution of control agreements in favor of CR concerning such Common Collateral. In order to help ensure that CR’s security interest in such Common Collateral is properly perfected (but subject to and without waiving the other provisions of this Agreement), [ ] agrees to hold both for itself and, solely for the purposes of perfection and without incurring any duties or obligations to CR as a result thereof or with respect thereto, for the benefit of CR, any such Common Collateral, and agrees that CR’s lien in such Common Collateral shall be deemed perfected in accordance with applicable law.

(b) CR acknowledges that applicable provisions of the UCC may require, in order to properly perfect [ ]’s security interest in the Common Collateral securing the [ ] Claims, that [ ] possess certain of such Common Collateral, and may require the execution of control agreements in favor of [ ] concerning such Common Collateral. In order to help ensure that [ ]’s security interest in such Common Collateral is properly perfected (but subject to and without waiving the other provisions of this Agreement), CR agrees to hold both for itself and, solely for the purposes of perfection and without incurring any additional duties or obligations to [ ] as a result thereof or with respect thereto, for the benefit of [ ], any such Common Collateral, and agrees that [ ]’s lien in such Common Collateral shall be deemed perfected in accordance with applicable law.

10. Credit Documents.

(a) Each Creditor represents and warrants that it has provided to the other true, correct and complete copies of all Credit Documents which relate to its credit agreement.

(b) At any time and from time to time, without notice to the other Creditor, each Creditor may take such actions with respect to its Claims as such Creditor, in its sole discretion, may deem appropriate, including, without limitation, terminating advances to Borrower, increasing the principal amount, extending the time of payment, increasing applicable interest to the default rate, renewing, compromising or otherwise amending the terms of any documents affecting its Claims and any Collateral therefor, and enforcing or failing to enforce any rights against Borrower or any other person. No such action or inaction shall impair or otherwise affect such Creditor’s rights hereunder. Each Creditor waives any benefits of California Civil Code Sections 2809, 2810, 2819, 2845, 2847, 2848, 2849, 2850, 2899 and 3433. Each Creditor waives the benefits, if any, of any statutory or common law rule that may permit a subordinating creditor to assert any defenses of a surety or guarantor, or that may give the subordinating creditor the right to require a senior creditor to marshal assets, and each Creditor agrees that it shall not assert any such defenses or rights.

(c) Each Creditor agrees that any other Creditor may release or refrain from enforcing its security interest in the Collateral, or permit the use or consumption of such Collateral by Borrower free of the other Creditor’s security interest, without incurring any liability to any other Creditor.

7

11. Waiver of Right to Require Marshaling. Each Creditor hereby expressly waives any right that it otherwise might have to require any other Creditor to marshal assets or to resort to Collateral in any particular order or manner, whether provided for by common law or statute. No Creditor shall be required to enforce any guaranty or any security interest or lien given by any person or entity as a condition precedent or concurrent to the taking of any Enforcement Action with respect to the Collateral.

12. Representations and Warranties. Each Creditor represents and warrants to the other that:

(a) all action on the part of such Creditor, its officers, directors, partners, members and shareholders, as applicable, necessary for the authorization of this Agreement and the performance of all obligations of such Creditor hereunder has been taken;

(b) this Agreement constitutes the legal, valid and binding obligation of such Creditor, enforceable against such Creditor in accordance with its terms;

(c) the execution, delivery and performance of and compliance with this Agreement by such Creditor will not (i) result in any material violation or default of any term of any of such Creditor’s charter, formation or other organizational documents (such as Articles or Certificate of Incorporation, bylaws, partnership agreement, operating agreement, etc.) or (ii) violate any material applicable law, rule or regulation.

13. Disgorgement.

(a) If, at any time after payment in full of the [ ] Claims any payments of the [ ] Claims must be disgorged by [ ] for any reason (including, without limitation, any Insolvency Proceeding), this Agreement and the relative rights and priorities set forth herein shall be reinstated as to all such disgorged payments as though such payments had not been made and CR shall immediately pay over to [ ] all money or funds received or retained by CR with respect to the CR Claims to the extent that such receipt or retention would have been prohibited hereunder.

(b) If, at any time after payment in full of the CR Claims any payments of the CR Claims must be disgorged by CR for any reason (including, without limitation, any Insolvency Proceeding), this Agreement and the relative rights and priorities set forth herein shall be reinstated as to all such disgorged payments as though such payments had not been made and [ ] shall immediately pay over to CR all money or funds received or retained by [ ] with respect to the [ ] Claims to the extent that such receipt or retention would have been prohibited hereunder.

14. Successors and Assigns. This Agreement shall bind any successors or assignees of each Creditor. This Agreement shall remain effective until all Claims are indefeasibly paid or otherwise satisfied in full and Creditors have no commitment to extend credit under the Credit Documents. This Agreement is solely for the benefit of the Creditors and not for the benefit of Borrower, any Obligor or any other party. Each Creditor shall not sell, assign, pledge, dispose of or otherwise transfer all or any portion of its Claims or any of its Credit Documents or any interest in any Common Collateral unless prior to the consummation of any such action, the

8

transferee thereof shall execute and deliver to the other Creditor an agreement of such transferee to be bound hereby, or an agreement substantially identical to this Agreement providing for the continued subjection of such Claims, the interests of the transferee in the Collateral and the remedies of the transferee with respect thereto as provided herein with respect to the transferring Creditor and for the continued effectiveness of all of the other rights of the other Creditor arising under this Agreement, in each case in form satisfactory to the other Creditor.

15. Further Assurances. Each Creditor hereby agrees to execute such documents and/or take such further action as the other Creditor may at any time or times reasonably request in order to carry out the provisions and intent of this Agreement, including, without limitation, ratifications and confirmations of this Agreement from time to time hereafter, as and when requested by the other Creditor.

16. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument.

17. Governing Law; Waiver of Jury Trial.

(a) This Agreement and the rights and obligations of the parties hereunder shall be governed by, and construed in accordance with, the law of the State of California without regard to principles of conflicts of laws that would result in the application of the laws of any other jurisdiction.

(b) EACH CREDITOR WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN.

18. Entire Agreement. This Agreement represents the entire agreement with respect to the subject matter hereof, and supersedes all prior negotiations, agreements and commitments. Each Creditor is not relying on any representations by the other Creditor or Borrower in entering into this Agreement, and each Creditor has kept and will continue to keep itself fully apprised of the financial and other condition of Borrower. This Agreement may be amended only by written instrument signed by the Creditors.

19. Relationship among Creditors. The relationship among the Creditors is, and at all times shall remain solely that of Creditors. Creditors shall not under any circumstances be construed to be partners or joint venturers of one another; nor shall the Creditors under any circumstances be deemed to be in a relationship of confidence or trust or a fiduciary relationship with one another, or to owe any fiduciary duty to one another. Creditors do not undertake or assume any responsibility or duty to one another to select, review, inspect, supervise, pass judgment upon or otherwise inform each other of any matter in connection with Borrower’s property, any Collateral held by any Creditor or the operations of Borrower. Each Creditor shall rely entirely on its own judgment with respect to such matters, and any review, inspection, supervision, exercise of judgment or supply of information undertaken or assumed by any Creditor in connection with such matters is solely for the protection of such Creditor.

20. Credit Agreements. Notwithstanding anything to the contrary in the CR Credit Agreement, the parties agree that (i) this Agreement shall be a “Loan Document” under the CR

9

Credit Agreement, and (ii) indebtedness of the Borrower under the [ ] Credit Agreement shall be “Permitted Priority Debt” under the CR Credit Agreement. Notwithstanding anything to the contrary in the [ ] Credit Agreement, the parties agree that (i) this Agreement shall be a “Loan Document” under the [ ] Credit Agreement, and (ii) indebtedness of the Borrower under the CR Credit Agreement shall be “Permitted Indebtedness” under the [ ] Credit Agreement.

21. Severability. Any provision of this Agreement which is illegal, invalid, prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent such illegality, invalidity, prohibition or unenforceability without invalidating or impairing the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

22. Notices. All notices, demands, instructions and other communications required or permitted to be given to or made upon any party hereto shall be in writing and shall be delivered or sent by first-class mail, postage prepaid, or by overnight courier or messenger service or by facsimile, message confirmed, and shall be deemed to be effective for purposes of this Agreement on the day that delivery is made or refused. Unless otherwise specified in a notice mailed or delivered in accordance with the foregoing sentence, notices, demands, instructions and other communications in writing shall be given to or made upon the respective parties hereto at their respective addresses and facsimile numbers indicated on the signature pages hereto.
