For purposes of computing interest, funds received by the Lender after that time on such due date shall be deemed to have been paid by the Borrower on the next succeeding Business Day, in the Lender’s sole discretion. Each such payment shall be made to the Lender at its address specified in Section 9.01. All payments hereunder and under each other Loan Document shall be made in Dollars.

(b) Except as otherwise expressly provided herein, whenever any payment (including principal of or interest on any Loan or other amounts) hereunder or under any other Loan Document shall become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest, if applicable.

(b) Any Escrow Funds delivered for conversion will be deemed to have been converted immediately prior to 5:00 p.m. New York time on Escrow Amount Conversion Date. The Lender shall be entitled to rights with regard to the Common Stock only to the extent such

The date on which the Lender satisfies all of the requirements in the immediately preceding sentence is the “Escrow Amount Conversion Date.” Upon receipt by the Borrower of the Escrow Funds delivered for conversion in accordance with Section 2.11(a), the Borrower shall deliver to the Lender the number of whole shares of Common Stock issuable upon the conversion thereof (and cash in lieu of any fractional shares) no later than five (5) Business Days following the relevant Escrow Amount Conversion Date.

SECTION 2.13. Adjustment of Conversion Rate . If at any time between (i) the execution of this Agreement and (ii) the date on which all amounts outstanding under this Agreement are paid by Borrower and/or all of the Loans and any Escrow Funds have been converted into Common Stock as provided herein, the number of outstanding shares of Common Stock shall (A) increase by virtue of or in connection with any dividend or distribution on the Common Stock or any stock split or other subdivision of the outstanding shares of Common Stock or a reclassification, then the Conversion Rate in effect immediately prior to such dividend, distribution, stock split or other subdivision shall, concurrently with the effectiveness of such increase, be adjusted to a Conversion Rate that would entitle the holder of any Loans and any Escrow Funds delivered for conversion to receive, from time to time upon conversion thereof, the same percentage of the outstanding shares of Common Stock that such holder would have received on conversion thereof had such Loan or Escrow Funds been outstanding and converted immediately prior to such increase and (B) decrease by virtue of or in connection with any combination or consolidation, by reclassification or otherwise, into a lesser number of shares of Common Stock (including, without limitation, pursuant to a reverse stock split), then the Conversion Rate in effect immediately prior to such combination, consolidation, reclassification, stock split or other process shall, concurrently with the effectiveness of such decrease, be adjusted to a Conversion Rate that would entitle the holder of any Loans and any Escrow Funds delivered for conversion to receive, from time to time upon conversion, the same percentage of the outstanding shares of Common Stock that such holder would have received on conversion

thereof had such Loan or Escrow Funds been outstanding and converted immediately prior to such decrease.

Guaranty

SECTION 7.01. Guaranty of the Obligations. (a) Guarantors jointly and severally hereby irrevocably and unconditionally guaranty to the Lender the due and punctual payment in full of all Obligations when the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code) (collectively, the “Guaranteed Obligations”).

(b) Each Guarantor and the Lender hereby confirms that it is the intention of all such Persons that this Guaranty and the Obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of any law related to fraudulent transfer or conveyance to the extent applicable to this Guaranty and the Obligations of the Guarantor hereunder. To effectuate the foregoing intention, the Lender and the Guarantors hereby irrevocably agree that the Obligations of each Guarantor under this Guaranty at any time shall be limited to the maximum amount as will result in the Obligations of such Guarantor under this Guaranty not constituting a fraudulent transfer or conveyance.

SECTION 7.02. Payment by Guarantors. Guarantors hereby jointly and severally agree, in furtherance of the foregoing and not in limitation of any other right which the Lender may have at law or in equity against any Guarantor by virtue hereof, that upon the failure of Borrower to pay any of the Guaranteed Obligations when and as the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code), Guarantors will upon demand pay, or cause to be paid, in cash, to the Lender, an amount equal to the sum of the unpaid principal amount of all Guaranteed Obligations then due as aforesaid, accrued and unpaid interest on such Guaranteed Obligations (including interest which, but for Borrower’s becoming the subject of a case under the Bankruptcy Code, would have accrued on such Guaranteed Obligations, whether or not a claim is allowed against Borrower for such interest in the related bankruptcy case) and all other Guaranteed Obligations then owed to the Lenders as aforesaid.

SECTION 7.03. Liability of Guarantors Absolute. Each Guarantor agrees that its obligations hereunder are irrevocable, absolute, independent and unconditional and shall not be affected by any circumstance which constitutes a legal or equitable discharge of a guarantor or surety other than payment in full of the Guaranteed Obligations. In furtherance of the foregoing and without limiting the generality thereof, each Guarantor agrees as follows:

(a) this Guaranty is a guaranty of payment when due and not of collectability. This Guaranty is a primary obligation of each Guarantor and not merely a contract of surety;

(b) the Lender may enforce this Guaranty upon the occurrence of an Event of Default notwithstanding the existence of any dispute between Borrower and the Lender with respect to the existence of such Event of Default;

(c) the obligations of each Guarantor hereunder are independent of the obligations of Borrower and the obligations of any other guarantor (including any other Guarantor) of the obligations of Borrower, and a separate action or actions may be brought and prosecuted against such Guarantor whether or not any action is brought against Borrower or any of such other guarantors and whether or not Borrower is joined in any such action or actions;

(d) payment by any Guarantor of a portion, but not all, of the Guaranteed Obligations shall in no way limit, affect, modify or abridge any Guarantor’s liability for any portion of the Guaranteed Obligations which has not been paid. Without limiting the generality of the foregoing, if the Lender is awarded a judgment in any suit brought to enforce any Guarantor’s covenant to pay a portion of the Guaranteed Obligations, such judgment shall not be deemed to release such Guarantor from its covenant to pay the portion of the Guaranteed Obligations that is not the subject of such suit, and such judgment shall not, except to the extent satisfied by such Guarantor, limit, affect, modify or abridge any other Guarantor’s liability hereunder in respect of the Guaranteed Obligations;

(e) the Lender, upon such terms as it deems appropriate, without notice or demand and without affecting the validity or enforceability hereof or giving rise to any reduction, limitation, impairment, discharge or termination of any Guarantor’s liability hereunder, from time to time may (i) renew, extend, accelerate, increase the rate of interest on, or otherwise change the time, place, manner or terms of payment of the Guaranteed Obligations; (ii) settle, compromise, release or discharge, or accept or refuse any offer of performance with respect to, or substitutions for, the Guaranteed Obligations or any agreement relating thereto and/or subordinate the payment of the same to the payment of any other obligations; (iii) request and accept other guaranties of the Guaranteed Obligations and take and hold security for the payment hereof or the Guaranteed Obligations; and (iv) exercise any other rights available to it under the Loan Documents; and

(f) this Guaranty and the obligations of Guarantors hereunder shall be valid and enforceable and shall not be subject to any reduction, limitation, impairment, discharge or termination for any reason (other than payment in full of the Guaranteed Obligations), including the occurrence of any of the following, whether or not any Guarantor shall have had notice or knowledge of any of them: (i) any failure or omission to assert or enforce or agreement or election not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of, any claim or demand or any right, power or remedy (whether arising under the Loan Documents, at law, in equity or otherwise) with respect to the Guaranteed Obligations or any agreement relating thereto, or with respect to any other guaranty of the payment of the Guaranteed Obligations; (ii) any rescission, waiver, amendment or modification of, or any consent to departure from, any of the terms or provisions (including provisions relating to Events of Default) hereof, any of the other Loan Documents or any agreement or instrument executed pursuant thereto, or of any other guaranty for the Guaranteed Obligations, in each case whether or not in accordance with the terms hereof or such Loan Document or any agreement relating to such other guaranty; (iii) the Guaranteed Obligations, or any agreement relating thereto, at any time being found to be illegal, invalid or unenforceable in any respect; (iv) the application of payments received from any source (other than payments received pursuant to the other Loan Documents) to the payment of indebtedness other than the Guaranteed Obligations, even though the Lender might have elected to apply such payment to

any part or all of the Guaranteed Obligations; (v) the Lender’s consent to the change, reorganization or termination of the corporate structure or existence of Borrower or any of its Subsidiaries and to any corresponding restructuring of the Guaranteed Obligations; (vi) any defenses, set offs or counterclaims which Borrower may allege or assert against the Lender in respect of the Guaranteed Obligations, including failure of consideration, breach of warranty, payment, statute of frauds, statute of limitations, accord and satisfaction and usury; and (vii) any other act or thing or omission, or delay to do any other act or thing, which may or might in any manner or to any extent vary the risk of any Guarantor as an obligor in respect of the Guaranteed Obligations.

SECTION 7.04. Waivers by Guarantors. Each Guarantor hereby waives, for the benefit of the Lender: (a) any right to require the Lender, as a condition of payment or performance by such Guarantor, to (i) proceed against Borrower, any other guarantor (including any other Guarantor) of the Guaranteed Obligations or any other Person, (ii) proceed against or exhaust any security held from Borrower, any such other guarantor or any other Person, (iii) proceed against or have resort to any balance of any deposit account or credit on the books of the Lender in favor of Borrower or any other Person, or (iv) pursue any other remedy in the power of the Lender whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of Borrower or any other Guarantor including any defense based on or arising out of the lack of validity or the unenforceability of the Guaranteed Obligations or any agreement or instrument relating thereto or by reason of the cessation of the liability of Borrower or any other Guarantor from any cause other than payment in full of the Guaranteed Obligations; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (d) any defense based upon the Lender’s errors or omissions in the administration of the Guaranteed Obligations, except behavior which amounts to bad faith; (e) (i) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms hereof and any legal or equitable discharge of such Guarantor’s obligations hereunder, (ii) the benefit of any statute of limitations affecting such Guarantor’s liability hereunder or the enforcement hereof, and (iii) any rights to set offs, recoupments and counterclaims; (f) notices, demands, presentments, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance hereof, notices of default hereunder, notices of any renewal, extension or modification of the Guaranteed Obligations or any agreement related thereto, notices of any extension of credit to Borrower and notices of any of the matters referred to in Section 7.03 and any right to consent to any thereof; and (g) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms hereof.

SECTION 7.05. Guarantors’ Rights of Subrogation, Contribution, Etc. Until the Guaranteed Obligations shall have been indefeasibly paid in full and the Commitments shall have terminated, each Guarantor hereby waives any claim, right or remedy, direct or indirect, that such Guarantor now has or may hereafter have against Borrower or any other Guarantor or any of its assets in connection with this Guaranty or the performance by such Guarantor of its obligations hereunder, in each case whether such claim, right or remedy arises in equity, under contract, by statute, under common law or otherwise and including (a) any right of subrogation, reimbursement or indemnification that such Guarantor now has or may hereafter have against Borrower with respect to the Guaranteed Obligations, and (b) any right to enforce, or to

participate in, any claim, right or remedy that the Lender now has or may hereafter have against Borrower. In addition, until the Guaranteed Obligations shall have been indefeasibly paid in full and the Commitments shall have terminated, each Guarantor shall withhold exercise of any right of contribution such Guarantor may have against any other guarantor (including any other Guarantor) of the Guaranteed Obligations. Each Guarantor further agrees that, to the extent the waiver or agreement to withhold the exercise of its rights of subrogation, reimbursement, indemnification and contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any rights of subrogation, reimbursement or indemnification such Guarantor may have against Borrower, and any rights of contribution such Guarantor may have against any such other guarantor, shall be junior and subordinate to any rights the Lender may have against Borrower to any right the Lender may have against such other guarantor. If any amount shall be paid to any Guarantor on account of any such subrogation, reimbursement, indemnification or contribution rights at any time when all Guaranteed Obligations shall not have been finally and indefeasibly paid in full, such amount shall be held in trust for the Lender and shall forthwith be paid over to the Lender to be credited and applied against the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms hereof.

SECTION 7.06. Subordination of Other Obligations. Any Indebtedness of Borrower or any Guarantor now or hereafter held by any Guarantor (the “Obligee Guarantor”) is hereby subordinated in right of payment to the Guaranteed Obligations, and any such Indebtedness collected or received by the Obligee Guarantor after an Event of Default has occurred and is continuing shall be held in trust for the Lender and shall forthwith be paid over to the Lender to be credited and applied against the Guaranteed Obligations but without affecting, impairing or limiting in any manner the liability of the Obligee Guarantor under any other provision hereof.

SECTION 7.07. Continuing Guaranty. This Guaranty is a continuing guaranty and shall remain in effect until all of the Guaranteed Obligations shall have been paid in full and the Commitments shall have terminated. Each Guarantor hereby irrevocably waives any right to revoke this Guaranty as to future transactions giving rise to any Guaranteed Obligations.

SECTION 7.08. Authority of Guarantors or Borrower. It is not necessary for the Lender to inquire into the capacity or powers of any Guarantor or Borrower or the officers, directors or any agents acting or purporting to act on behalf of any of them.

SECTION 7.09. Financial Condition of Borrower. Any Loan may be made to Borrower or continued from time to time without notice to or authorization from any Guarantor regardless of the financial or other condition of Borrower at the time of any such grant or continuation. The Lender shall have no obligation to disclose or discuss with any Guarantor its assessment, or any Guarantor’s assessment, of the financial condition of Borrower. Each Guarantor has adequate means to obtain information from Borrower on a continuing basis concerning the financial condition of Borrower and its ability to perform its obligations under the Loan Documents and each Guarantor assumes the responsibility for being and keeping informed of the financial condition of Borrower and of all circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations. Each Guarantor hereby waives and relinquishes any duty on the part of the Lender to disclose any matter, fact or thing relating to the business, operations or conditions of Borrower now known or hereafter known by the Lender.

SECTION 7.10. Bankruptcy, Etc. (a) So long as any Guaranteed Obligations remain outstanding, no Guarantor shall, without the prior written consent of the Lender, commence or join with any other Person in commencing any bankruptcy, reorganization or insolvency case or proceeding of or against Borrower or any other Guarantor. The obligations of Guarantors hereunder shall not be reduced, limited, impaired, discharged, deferred, suspended or terminated by any case or proceeding, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement of Borrower or any other Guarantor or by any defense which Borrower or any other Guarantor may have by reason of the order, decree or decision of any court or administrative body resulting from any such proceeding.

(b) Each Guarantor acknowledges and agrees that any interest on any portion of the Guaranteed Obligations which accrues after the commencement of any case or proceeding referred to in clause (a) above (or, if interest on any portion of the Guaranteed Obligations ceases to accrue by operation of law by reason of the commencement of such case or proceeding, such interest as would have accrued on such portion of the Guaranteed Obligations if such case or proceeding had not been commenced) shall be included in the Guaranteed Obligations because it is the intention of Guarantors and the Lender that the Guaranteed Obligations which are guaranteed by Guarantors pursuant hereto should be determined without regard to any rule of law or order which may relieve Borrower of any portion of such Guaranteed Obligations. Guarantors will permit any trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit of creditors or similar Person to pay the Lender, or allow the claim of the Lender in respect of, any such interest accruing after the date on which such case or proceeding is commenced.

(c) In the event that all or any portion of the Guaranteed Obligations are paid by Borrower, the obligations of Guarantors hereunder shall continue and remain in full force and effect or be reinstated, as the case may be, in the event that all or any part of such payment(s) are rescinded or recovered directly or indirectly from the Lender as a preference, fraudulent transfer or otherwise, and any such payments which are so rescinded or recovered shall constitute Guaranteed Obligations for all purposes hereunder.

ARTICLE VIII.

(g) an involuntary proceeding shall be commenced or an involuntary petition shall be filed in a court of competent jurisdiction seeking (i) relief in respect of the Borrower , or of a substantial part of the property or assets of the Borrower under the Bankruptcy Code, as now constituted or hereafter amended, or any other Federal, state or foreign bankruptcy, insolvency, receivership or similar law, (ii) the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for the Borrower or for a substantial part of the property or assets of the Borrower or (iii) the winding-up or liquidation of the Borrower; and such proceeding or petition shall continue undismissed for 60 days or an order or decree approving or ordering any of the foregoing shall be entered;

(h) the Borrower shall (i) voluntarily commence any proceeding or file any petition seeking relief under the Bankruptcy Code, as now constituted or hereafter amended, or any other Federal, state or foreign bankruptcy, insolvency, receivership or similar law, (ii) consent to the institution of, or fail to contest in a timely and appropriate manner, any proceeding or the filing of any petition described in (g) above, (iii) apply for or consent to the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for the Borrower or for a substantial part of the property or assets of the Borrower, (iv) file an answer admitting the material allegations of a petition filed against it in any such proceeding, (v) make a general assignment for the benefit of creditors, (vi) admit in writing its inability or fail generally to pay its debts as they become due or (vii) take any action for the purpose of effecting any of the foregoing;

(i) one or more judgments for the payment of money that, individually or in the aggregate, would reasonably be expected to result in a Company Material Adverse Effect shall

be rendered against the Borrower or any combination thereof and the same shall remain undischarged for a period of thirty (30) consecutive days during which execution shall not be effectively stayed, or any action shall be legally taken by a judgment creditor to levy upon assets or properties of the Borrower to enforce any such judgment; or

(j) the Borrower shall fail to repay on the date required pursuant to Section 2.06 the entire principal amount of and accrued interest on the Loans,

then, and in every such event (other than an event with respect to the Borrower described in paragraph (g) or (h) above), and at any time thereafter during the continuance of such event either or both of the following actions may be taken: the Lender by notice to the Borrower may declare the Loans then outstanding to be forthwith due and payable in whole or in part, whereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and all other liabilities of the Borrower accrued hereunder and under any other Loan Document, shall become forthwith due and payable, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Borrower, anything contained herein or in any other Loan Document to the contrary notwithstanding, and the Lender shall have the right to take all or any actions and exercise any remedies available to them under this Agreement, applicable law or in equity; and in any event with respect to the Borrower described in paragraph (g) or (h) above, the principal of the Loans then outstanding, together with accrued interest thereon and all other liabilities of the Borrower accrued hereunder and under any other Loan Document, shall automatically become due and payable, without presentment, demand, protest or any other notice of any kind, all of which are hereby expressly waived by the Borrower, anything contained herein or in any other Loan Document to the contrary notwithstanding, and the Lender shall have the right to take all or any actions and exercise any remedies available to them under this Agreement, applicable law or in equity.

SECTION 9.02. Survival of Agreement. All rights, covenants, agreements, representations and warranties made by the Borrower in this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that any such other party may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as (i) the principal of or any accrued interest on any Loan or any other amount payable under this Agreement is outstanding and unpaid, (ii) any Convertible Portion of the Loans has not been converted into Common Stock and (iii) any amount remains in the Escrow Account that has not been converted into Common Stock.

SECTION 9.03. Binding Effect. This Agreement shall become effective when it shall have been executed by each of the parties hereto and thereto and when the Lender shall have received counterparts hereof and thereof which, when taken together, bear the signatures of each of the other parties hereto and thereto.

SECTION 9.04. Successors and Assigns. (a) Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to include the permitted successors and assigns of such party; and all covenants, promises and agreements by or on behalf of the Borrower or the Lender that are contained in this Agreement shall bind and inure to the benefit of their respective successors and assigns.

(b) Neither the Lender nor the Borrower shall assign or delegate any of its rights or duties hereunder to any Person (other than with respect to the Borrower by operation of law to ▇▇▇▇▇▇ Merger Sub I, Inc. and ▇▇▇▇▇▇ Merger Sub II, Inc., or their respective successors and assigns, in the Acquisition) without the prior written consent of the Lender or the Borrower, as applicable, and any attempted assignment without such prior written consent shall be null and void.

(c) The Borrower and the Lender intend that the Loans (including any promissory notes evidencing such Loans) shall be obligations in “registered form” within the meaning of section 163(f) of the Internal Revenue Code of 1986, as amended, and section 5f.103-1(c) of the

Treasury Regulations (and any successor provisions) at all times during which the Loans remain in effect. Neither the Borrower nor the Lender shall take any action or otherwise permit such obligation to become an obligation that is not in “registered form.” The Borrower shall maintain a register for the recordation of the name and address of the Lender (and any permitted assignees pursuant to Section 9.04(b)) and principal and interest shall only be paid to such persons recorded in the register. The register is intended to function as a “book entry” system within the meaning of sections 5f.103-1(c)(1)(ii) and 5f.103–1(c)(2) of the Treasury Regulations (and any successor provisions).

SECTION 9.05. Right of Setoff.

The rights of the Lender under this Section 9.05 are in addition to other rights and remedies (including other rights of setoff) which the Lender may have.

SECTION 9.06. Applicable Law. THIS AGREEMENT AND THE NOTES SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES THEREOF.

SECTION 9.07. Waivers; Amendment. (a) No failure or delay of the Lender in exercising any power or right hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Lender hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that it would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Lender.

SECTION 9.08. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan or

participation in accordance with applicable law, the rate of interest payable in respect of such Loan or participation hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan or participation but were not payable as a result of the operation of this Section 9.08 shall be cumulated and the interest and Charges payable to the Lender in respect of other Loans or participations or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by the Lender.

SECTION 9.09. Entire Agreement. This Agreement, the other Loan Documents, the Definitive Agreement and the other documents contemplated hereby and thereby constitute the entire contract between the parties relative to the subject matter hereof. Any other previous agreement among the parties with respect to the subject matter hereof is superseded by this Agreement, the other Loan Documents, the Definitive Agreement and the other documents contemplated hereby and thereby. Nothing in this Agreement or in the other Loan Documents, expressed or implied, is intended to confer upon any person (other than the parties hereto and thereto, their respective successors and assigns permitted hereunder and, to the extent expressly contemplated hereby, the Related Parties of the Lender) any rights, remedies, obligations or liabilities under or by reason of this Agreement or the other Loan Documents.

SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.10.

SECTION 9.11. Severability. In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 9.12. Counterparts. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original but all of which when taken together shall constitute a single contract, and shall become effective as provided in Section 9.03. Delivery of an executed signature page to this Agreement by facsimile

or other electronic transmission shall be as effective as delivery of a manually signed counterpart of this Agreement.

SECTION 9.13. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement.

SECTION 9.14. Jurisdiction; Consent to Service of Process. (a) The Borrower and the Lender each irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of any New York State court or Federal court of the United States of America sitting in the Borough of Manhattan, New York, New York and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court sitting in the Borough of Manhattan, New York, New York. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(a) Each party hereto hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any New York State or Federal court sitting in the Borough of Manhattan, New York, New York. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(b) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 9.15. No Fiduciary Duty. The Lender and its Affiliates (collectively, solely for purposes of this paragraph, the “Lender”), may have economic interests that conflict with those of the Borrower. The Borrower agrees that nothing in the Loan Documents or otherwise will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between the Lender and the Borrower, its stockholders or its affiliates. The Borrower acknowledge and agree that (i) the transactions contemplated by the Loan Documents are arm’s-length commercial transactions between the Lender, on the one hand, and the Borrower, on the other, (ii) in connection therewith and with the process leading to such transaction the Lender is acting solely as a principal and not the agent or fiduciary of the Borrower, its management, stockholders, creditors or any other Person, (iii) the Lender has not assumed an advisory or fiduciary responsibility in favor of the Borrower with respect to the transactions contemplated hereby or the process leading thereto (irrespective of whether the Lender or any of its affiliates has advised or is currently advising the Borrower on other matters) or any other obligation to the Borrower except the obligations expressly set forth in the Loan Documents and (iv) the Borrower has consulted its own legal and financial advisors to the extent they deemed appropriate. The Borrower further acknowledges and agrees that it is responsible for making its own independent

judgment with respect to such transactions and the process leading thereto. The Borrower agrees that it will not claim that the Lender has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Borrower, in connection with such transaction or the process leading thereto.
