THIS LOAN AND SECURITY AGREEMENT (this "Agreement"), dated as of September 5, 2012 (the "Closing Date") by and among MIDCAP FINANCIAL SBIC, LP, a Delaware limited partnership ("MidCap"), as administrative agent ("Agent"), the Lenders listed on Schedule 1 hereto and otherwise party hereto from time to time (each a "Lender", and collectively the "Lenders"), and KALOBIOS PHARMACEUTICALS, INC., a Delaware corporation ("Borrower"), provides the terms on which Lenders agree to lend to Borrower and Borrower shall repay Lenders. The parties agree as follows:


1. ACCOUNTING AND OTHER TERMS

Accounting terms not defined in this Agreement shall be construed in accordance with GAAP. Calculations and determinations must be made in accordance with GAAP. Capitalized terms not otherwise defined in this Agreement shall have the meanings set forth in Section 14. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the Code to the extent such terms are defined therein.


2. LOAN AND TERMS OF PAYMENT

2.1 Promise to Pay. Borrower hereby unconditionally promises to pay to Agent, for payment to each Lender in accordance with its respective Pro Rata Share, the outstanding principal amount of all Credit Extensions made by the Lenders, and accrued and unpaid interest thereon, and any other amounts due hereunder as and when due in accordance with this Agreement.

2.2 Term Loans.

(a) Availability. Subject to the terms and conditions of this Agreement, during the Draw Period, the Lenders agree, severally and not jointly, to make one or more term loans to Borrower in an aggregate amount up to Fifteen Million Dollars ($15,000,000) according to each Lender's Term Loan Commitment as set forth on Schedule 1 hereto (such term loans are hereinafter referred to singly as a "Term Loan", and collectively as the "Term Loans"). After repayment, no Term Loan may be re-borrowed. The Term Loans shall be available in three (3) tranches. The first tranche ("Tranche One") shall be in an amount not less than Five Million Dollars ($5,000,000), but not to exceed Ten Million Dollars ($10,000,000), and shall be advanced on the Closing Date. The second tranche ("Tranche Two") shall be in an amount equal to Ten Million Dollars ($10,000,000) less the amount advanced under Tranche One, and shall be available to be advanced in a single advance during the Draw Period. The Third Tranche ("Tranche Three") shall be in amount equal to Five Million Dollars ($5,000,000) and shall be available in a single advance during the Draw Period. Notwithstanding anything set forth herein to the contrary, it is understood and agreed that Borrower is required to draw not less than Ten Million Dollar ($10,000,000) on or prior to the Draw Period Termination Date. Subject to the terms and conditions set forth in Section 12.1, Borrower may not assign its right to request the Term Loans.

(b) Interest Payments and Repayment. Commencing on the first (1st) Payment Date following the Funding Date of Tranche One, of Tranche Two and Tranche Three, respectively, and continuing on the Payment Date of each successive month thereafter through and including the Maturity Date, Borrower shall make monthly payments of interest to Agent, for payment to each Lender in accordance with its respective Pro Rata Share, in arrears, and calculated as set forth in Section 2.3. Commencing on the Amortization Date, and continuing on the Payment Date of each successive month thereafter through and including the Maturity Date, Borrower shall make consecutive monthly payments of principal to Agent, for payment to each Lender in accordance with its respective Pro Rata Share, as calculated by Agent based upon: (i) the amount of such Lender's Term Loans, (ii) the effective rate of interest, as determined in Section 2.3, and (iii) a straight-line amortization schedule for each Credit Extension beginning on the Amortization Date and ending on the Maturity Date. All unpaid principal and accrued interest with respect to the Term Loans is due and payable in full on the Maturity Date. The Term Loans may be prepaid only in accordance with Sections 2.2(c) and 2.2(d).


(c) Mandatory Prepayments. If the Term Loans are accelerated following the occurrence of an Event of Default, Borrower shall immediately pay to Agent, for payment to each Lender in accordance with its respective Pro Rata Share, an amount equal to the sum of: (i) all outstanding principal of the Term Loans and all other Obligations, and all accrued and unpaid interest thereon, plus (ii) the Final Payment, plus (iii) the Prepayment Fee, plus (iv) all other sums that shall have become due and payable, including Lenders' Expenses.

(d) Permitted Prepayment of Loans. Borrower shall have the option to prepay all or a portion of the Term Loans advanced by the Lenders under this Agreement; provided, however, that Borrower (i) provides written notice to Agent of its election to prepay the Term Loans at least thirty (30) days prior to such prepayment, and (ii) pays to Agent, for payment to each Lender in accordance with its respective Pro Rata Share, on the date of such prepayment, an amount equal to the sum of: (A) all amount of the Term Loan and Obligations (plus accrued and unpaid interest thereon) being prepaid, plus (B) the Final Payment applicable to the amount being prepaid, plus (C) the Prepayment Fee applicable to the amount being prepaid, plus (D) all other sums that shall have become due and payable, including Lenders' Expenses.

2.3 Payment of Interest on the Credit Extensions.

(a) Computation of Interest. Interest on the Credit Extensions and all fees payable hereunder shall be computed on the basis of a 360-day year and the actual number of days elapsed in the period during which such interest accrues. In computing interest on any Credit Extension, the date of the making of such Credit Extension shall be included and the date of payment shall be excluded; provided, however, that if any Credit Extension is repaid on the same day on which it is made, such day shall be included in computing interest on such Credit Extension.

(b) Interest Rate Determination. Subject to the provisions of Section 2.3(c) below, each Term Loan shall bear interest on the outstanding principal amount thereof from the date when made until paid in full at a rate per annum equal to the sum of (i) the greater of (A) the LIBOR Rate in effect for the applicable Interest Period and (B) three percent (3.00%), plus (ii) the LIBOR Rate Margin adjusted on the first (1st) day of each Interest Period and fixed for the duration of each such Interest Period. As of each Interest Rate Determination Date, Agent shall determine (which determination shall, absent manifest error in calculation, be final, conclusive and binding upon all parties) the interest rate that shall apply to the Term Loan for which an interest rate is then being determined for the applicable Interest Period. In the event that Agent shall have determined (which determination shall be final and conclusive and binding upon all parties hereto), as of any Interest Rate Determination Date with respect to any Term Loan, that adequate and fair means do not exist for ascertaining the interest rate applicable to such Term Loan on the basis provided for in the definition of Base LIBOR Rate, then Agent may select a comparable replacement index and corresponding margin.

(c) Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, Obligations shall bear interest at a rate per annum that is five percent (5.0%) above the rate that is otherwise applicable thereto (the "Default Rate"). Payment or acceptance of the increased interest rate provided in this Section 2.3(c) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Agent or Lenders.

(d) Debit of Accounts. Agent may debit any of Borrower's Deposit Accounts, including the Designated Deposit Account, for principal and interest payments when due or any other amounts Borrower owes the Lenders under the Loan Documents when due, for payment to each Lender in accordance with its respective Pro Rata Share. These debits shall not constitute a set-off.

(e) Payments. Payments of principal and/or interest received after 12:00 Noon Eastern Time are considered received at the opening of business on the next Business Day. When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest, as applicable, shall continue to accrue until paid. All payments to be made by Borrower hereunder or under any other Loan Document, including payments of principal and interest made hereunder and pursuant to any other Loan Document, and all fees, expenses, indemnities and reimbursements, shall be made without set-off, recoupment or counterclaim, in lawful money of the United States and in immediately available funds. All payments required under this Agreement are to be made directly to Agent unless otherwise directed by Agent in writing.


2


(f) Maximum Lawful Rate. In no event shall the interest charged hereunder, with respect to the notes (if any) or any other obligations of Borrower under any of the Loan Documents exceed the maximum amount permitted under the Laws of the State of Maryland. Notwithstanding anything to the contrary herein or elsewhere, if at any time the rate of interest payable hereunder or under any note or other Loan Document (the "Stated Rate") would exceed the highest rate of interest permitted under any applicable Law to be charged (the "Maximum Lawful Rate"), then for so long as the Maximum Lawful Rate would be so exceeded, the rate of interest payable shall be equal to the Maximum Lawful Rate; provided, however, that if at any time thereafter the Stated Rate is less than the Maximum Lawful Rate, Borrower shall, to the extent permitted by Law, continue to pay interest at the Maximum Lawful Rate until such time as the total interest received is equal to the total interest which would have been received had the Stated Rate been (but for the operation of this provision) the interest rate payable. Thereafter, the interest rate payable shall be the Stated Rate unless and until the Stated Rate again would exceed the Maximum Lawful Rate, in which event this provision shall again apply. In no event shall the total interest received by any Lender exceed the amount which it could lawfully have received, had the interest been calculated for the full term hereof at the Maximum Lawful Rate. If, notwithstanding the prior sentence, any Lender has received interest hereunder in excess of the Maximum Lawful Rate, then such excess amount shall be applied to the reduction of the principal balance of such Lender's Term Loan or to other amounts (other than interest) payable hereunder, and if no such principal or other amounts are then outstanding, such excess or part thereof remaining shall be paid to Borrower. In computing interest payable with reference to the Maximum Lawful Rate applicable to any Lender, such interest shall be calculated at a daily rate equal to the Maximum Lawful Rate divided by the number of days in the year in which such calculation is made.

2.4 Fees and Expenses. Borrower shall pay to Agent, for payment to each Lender:

(a) Closing Fee. A non refundable closing fee to each Lender, in accordance with its respective Pro Rata Share, equal to the product of (i) one half of one percent (0.50%) multiplied by (ii) the aggregate Term Loan Commitment on the Closing Date, which shall be due and payable on the Funding Date of Tranche One;

(b) Final Payment. The Final Payment, when due under Section 2.2(c) or 2.2(d), or otherwise on the Maturity Date, to each Lender, in accordance with its respective Pro Rata Share;

(c) Prepayment Fee. The Prepayment Fee, when due under Section 2.2(c) or 2.2(d), to each Lender, in accordance with its respective Pro Rata Share immediately prior to application of the corresponding prepayment;

(d) Good Faith Deposit. Borrower has paid to Agent, for payment to each Lender, a deposit of Seventy Five Thousand Dollars ($75,000) (the "Good Faith Deposit") to initiate Agent's due diligence review process. On the Closing Date, such Good Faith Deposit will be applied to the Closing Fee; and

(e) Lenders' Expenses. All of Lenders' Expenses (including reasonable attorneys' fees and expenses for documentation and negotiation of this Agreement) incurred through and after the Closing Date, when due (and in the absence of any other due date specified herein, such Lenders' Expenses shall be due upon demand).

2.5 Additional Costs. If any new Law or regulation increases a Lender's costs or reduces its income for any Term Loan, Borrower shall pay the increase in cost or reduction in income or additional expense; provided, however, that Borrower shall not be liable for any amount attributable to any period before one hundred eighty (180) days prior to the date such Lender notifies Borrower of such increased costs. Each Lender agrees that it shall allocate any increased costs among its customers similarly affected in good faith and in a manner consistent with such Lender's customary practice.

2.6 Payments and Taxes. Any and all payments made by Borrower under this Agreement or any other Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, duties, deductions, withholdings, assessments, fees or other charges imposed by any governmental authority (including any interest, additions to tax or penalties applicable thereto) other than any taxes imposed on or measured by any Lender's overall net income and franchise taxes imposed on it (in lieu of net income taxes), by a jurisdiction (or any political subdivision thereof) as a result of any Lender being organized or resident, conducting business (other than a business deemed to arise from such Lender having executed, delivered or performed its


3


obligations or received a payment under, or enforced, or otherwise with respect to, this Agreement or any other Loan Document) or having its principal office in such jurisdiction ("Indemnified Taxes"). If any Indemnified Taxes shall be required by Law to be withheld or deducted from or in respect of any sum payable under this Agreement or any other Loan Document to any Lender, (a) an additional amount shall be payable as may be necessary so that, after making all required withholdings or deductions (including withholdings or deductions applicable to additional sums payable under this Section) such Lender receives an amount equal to the sum it would have received had no such withholdings or deductions been made, (b) Borrower shall make such withholdings or deductions, (c) Borrower shall pay the full amount withheld or deducted to the relevant taxing authority or other authority in accordance with applicable Law, and (d) Borrower shall deliver to such Lender evidence of such payment. Borrower's obligation hereunder shall survive the termination of this Agreement.

2.7 Secured Promissory Notes. Each Term Loan shall be evidenced by a Secured Promissory Note in the form attached as Exhibit D hereto (each a "Secured Promissory Note"), and shall be repayable as set forth herein. Borrower irrevocably authorizes each Lender to make or cause to be made, on or about the Funding Date of any Term Loan or at the time of receipt of any payment of principal on such Lender's Secured Promissory Note, an appropriate notation on such Lender's Secured Promissory Note Record reflecting the making of such Term Loan or (as the case may be) the receipt of such payment. The outstanding amount of each Term Loan set forth on such Lender's Secured Promissory Note Record shall be prima facie evidence of the principal amount thereof owing and unpaid to such Lender, but the failure to record, or any error in so recording, any such amount on such Lender's Secured Promissory Note Record shall not limit or otherwise affect the obligations of Borrower hereunder or under any Secured Promissory Note to make payments of principal of or interest on any Secured Promissory Note when due. Upon receipt of an affidavit of an officer of a Lender as to the loss, theft, destruction, or mutilation of its Secured Promissory Note, Borrower shall issue, in lieu thereof, a replacement Secured Promissory Note in the same principal amount thereof and of like tenor.

2.8 Issuance of Warrants to Lenders. Borrower has duly authorized and issued to Lenders warrants, the form of which is attached hereto as Exhibit E (collectively, the "Warrants"), evidencing Lenders' (or their respective affiliates or designees) right to acquire their respective Pro Rata Share of the class of stock of Borrower, on the terms and conditions set forth in the Warrants, as necessary to comply with the requirements of the Loan Documents.

2.9 SBIC Acknowledgement. Borrower acknowledges that Agent is a Federal licensee under the Small Business Investment Act of 1958, as amended.

5.4 No Material Deterioration in Financial Condition; Financial Statements. All consolidated financial statements for Borrower and any of its Subsidiaries delivered to Agent fairly present, in conformity with GAAP, in all material respects Borrower's consolidated financial condition and Borrower's consolidated results of operations as of the date of such financial statements. There has not been any material deterioration in Borrower's consolidated financial condition since the date of the most recent financial statements and projections submitted to Agent.

5.5 Solvency. The fair salable value of Borrower's assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities. After giving effect to the transactions described in this Agreement, (a) Borrower is not left with unreasonably small capital in relation to its business as presently conducted, and (b) Borrower is able to pay its debts (including trade debts) as they mature.

5.6 Regulatory Compliance.

(a) Borrower is not an "investment company" or a company "controlled" by an "investment company" under the Investment Company Act of 1940, as amended. Borrower is not engaged in the business of purchasing or selling margin stock and/or extending credit for the purpose of purchasing margin stock (under Regulations X, T and U of the Federal Reserve Board of Governors). As of the Closing Date, except as set forth on Schedule B, no Loan Party and no Subsidiary of any Loan Party owns any Margin Stock. Borrower has complied in all material respects with the Federal Fair Labor Standards Act. Neither Borrower nor any of its Subsidiaries is a "holding company" or an "affiliate" of a "holding company" or a "subsidiary company" of a "holding company", as each term is defined and used in the Public Utility Holding Company Act of 2005. Borrower has not violated any Laws, ordinances or rules, the violation of which could reasonably be expected to have a Material Adverse Change. None of Borrower's or any of its Subsidiaries' properties or assets has been used by Borrower or any Subsidiary or, to Borrower's knowledge, by previous Persons, in disposing, producing, storing, treating, or transporting any hazardous substance other than in material compliance with applicable Laws. Borrower has obtained all Required Permits, or has contracted with third parties holding Required Permits, necessary for compliance in all material respects with all Laws and all such Required Permits are current. Borrower and each of its Subsidiaries have obtained all material consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all Governmental Authorities that are necessary to continue their respective businesses as currently conducted.

(b) None of the Borrower, its Affiliates or any of their respective agents acting or benefiting in any capacity in connection with the transactions contemplated by this Agreement is (i) in violation of any Anti-Terrorism Law, (ii) engages in or conspires to engage in any transaction that evades or avoids, or has the purpose of evading or avoiding or attempts to violate, any of the prohibitions set forth in any Anti-Terrorism Law, or (iii) is a Blocked Person. Neither Borrower nor, to the knowledge of Borrower, any of its Affiliates or agents acting or benefiting in any capacity in connection with the transactions contemplated by this Agreement, (x) conducts any business or engages in making or receiving any contribution of funds, goods or services to or for the benefit of any Blocked Person, or (y) deals in, or otherwise engages in any transaction relating to, any property or interest in property blocked pursuant to Executive Order No. 13224, any similar executive order or other Anti-Terrorism Law.

5.7 Subsidiaries; Investments. Borrower does not own any stock, partnership interest or other equity securities, except for Permitted Investments.

5.8 Tax Returns and Payments; Pension Contributions. Borrower has timely filed all required tax returns or tax extensions and reports (except where the failure to file any such tax return, extension or report does not result in penalties or other liabilities to Borrower in excess of, individually or in the aggregate at any time, Twenty Thousand Dollars ($20,000), and there are no Liens on any of the Collateral in favor of a Governmental Authority resulting from the failure to file any such tax return, extension or report except for "Permitted Liens"), and Borrower and its Subsidiaries have timely paid all foreign, federal, state and local taxes, assessments, deposits and contributions owed by Borrower, except for such taxes, assessments, deposits and contributions that do not at any time exceed an amount of, individually or in the aggregate, Twenty Thousand Dollars ($20,000) and there are no Liens on any of the Collateral in favor of a Governmental Authority resulting from such unpaid taxes, assessments, deposits and contributions except for "Permitted Liens". Borrower may defer payment of any contested taxes, provided, however, that Borrower (a) in good faith contests its obligation to pay the taxes by appropriate


8

9. RIGHTS AND REMEDIES

9.1 Rights and Remedies.

(a) Upon the occurrence and during the continuance of an Event of Default, Agent may, without notice or demand, do any or all of the following: (i) deliver notice of the Event of Default to Borrower, (ii) by notice to Borrower declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all Obligations shall be immediately due and payable without any action by Agent or the Lenders), or (iii) by notice to Borrower suspend or terminate the obligations, if any, of the Lenders to advance money or extend credit for Borrower's benefit under this Agreement or under any other agreement between Borrower and Agent and/or the Lenders (but if an Event of Default described in Section 8.5 occurs all obligations, if any, of the Lenders to advance money or extend credit for Borrower's benefit under this Agreement or under any other agreement between Borrower and Agent and/or the Lenders shall be immediately terminated without any action by Agent or the Lenders).

(b) Without limiting the rights of Agent and Lenders set forth in Section 9.1(a) above, upon the occurrence and during the continuance of an Event of Default, Agent shall have the right, at the written direction of the Required Lenders, without notice or demand, to do any or all of the following:

(i) foreclose upon and/or sell or otherwise liquidate, the Collateral;

(ii) apply to the Obligations any (a) balances and deposits of Borrower that Agent or any Lender holds or controls, or (b) any amount held or controlled by Agent or any Lender owing to or for the credit or the account of Borrower; and/or


17


(iii) commence and prosecute an Insolvency Proceeding or consent to Borrower commencing any Insolvency Proceeding.

(c) Without limiting the rights of Agent and Lenders set forth in Sections 9.1(a) and ((b)) above, upon the occurrence and during the continuance of an Event of Default Agent shall have the right, without notice or demand, to do any or all of the following:

(i) settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Agent considers advisable, notify any Person owing Borrower money of Agent's security interest in such funds, and verify the amount of such Account;

(ii) make any payments and do any acts it considers necessary or reasonable to protect the Collateral and/or its security interest in the Collateral. Borrower shall assemble the Collateral if Agent requests and make it available as Agent designates. Agent may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Agent a license to enter and occupy any of its premises, without charge, to exercise any of Agent's rights or remedies;

(iii) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, and/or advertise for sale, the Collateral. Agent is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower's labels, patents, copyrights, mask works, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Agent's exercise of its rights under this Section 9.1, Borrower's rights under all licenses and all franchise agreements inure to Agent for the benefit of the Lenders;

(iv) place a "hold" on any account maintained with Agent or the Lenders and/or deliver a notice of exclusive control, any entitlement order, or other directions or instructions pursuant to any Control Agreement or similar agreements providing control of any Collateral;

(v) demand and receive possession of Borrower's Books; and

(vi) subject to clauses 9.1(a)and (b), exercise all rights and remedies available to Agent under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof).

Notwithstanding any provision of this Section 9.1 to the contrary, upon the occurrence of any Event of Default, Agent shall have the right to exercise any and all remedies referenced in this Section 9.1 without the written consent of Required Lenders following the occurrence of an Exigent Circumstance. As used in the immediately preceding sentence, "Exigent Circumstance" means any event or circumstance that, in the reasonable judgment of Agent, imminently threatens the ability of Agent to realize upon all or any material portion of the Collateral, such as, without limitation, fraudulent removal, concealment, or abscondment thereof, destruction or material waste thereof, or failure of Borrower after reasonable demand to maintain or reinstate adequate casualty insurance coverage, or which, in the judgment of Agent, could result in a material diminution in value of the Collateral.

9.2 Power of Attorney. Borrower hereby irrevocably appoints Agent as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower's name on any checks or other forms of payment or security; (b) sign Borrower's name on any invoice or bill of lading for any Account or drafts against Account Debtors; (c) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts and on terms Agent determines reasonable; (d) make, settle, and adjust all claims under Borrower's insurance policies; (e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of Agent or a third party as the Code permits. Borrower hereby appoints Agent as its lawful attorney-in-fact to sign Borrower's name on any documents necessary to perfect or continue the perfection of Agent's security interest in the Collateral regardless of whether an


18


Event of Default has occurred until all Obligations have been satisfied in full and Agent and the Lenders are under no further obligation to make Credit Extensions hereunder. Agent's foregoing appointment as Borrower's attorney in fact, and all of Agent's rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Agent's and the Lenders' obligation to provide Credit Extensions terminates.

9.3 Protective Payments. If Borrower fails to obtain the insurance called for by Section 6.5 or fails to pay any premium thereon or fails to pay any other amount which Borrower is obligated to pay under this Agreement or any other Loan Document, Agent may obtain such insurance or make such payment, and all amounts so paid by Agent are Lenders' Expenses and immediately due and payable, bearing interest at the then highest applicable rate, and secured by the Collateral. Agent will make reasonable efforts to provide Borrower with notice of Agent obtaining such insurance at the time it is obtained or within a reasonable time thereafter. No such payments by Agent are deemed an agreement to make similar payments in the future or Agent's waiver of any Event of Default.

9.4 Application of Payments and Proceeds.

(a) Notwithstanding anything to the contrary contained in this Agreement, upon the occurrence and during the continuance of an Event of Default, (i) Borrower irrevocably waives the right to direct the application of any and all payments at any time or times thereafter received by Agent from or on behalf of Borrower of all or any part of the Obligations, and, as between Borrower on the one hand and Agent and Lenders on the other, Agent shall have the continuing and exclusive right to apply and to reapply any and all payments received against the Obligations in such manner as Agent may deem advisable notwithstanding any previous application by Agent, and (ii) the proceeds of any sale of, or other realization upon all or any part of the Collateral shall be applied: first, to the Lenders Expenses; second, to accrued and unpaid interest on the Obligations (including any interest which, but for the provisions of the United States Bankruptcy Code, would have accrued on such amounts); third, to the principal amount of the Obligations outstanding; and fourth, to any other indebtedness or obligations of Borrower owing to Agent or any Lender under the Loan Documents. Any balance remaining shall be delivered to Borrower or to whoever may be lawfully entitled to receive such balance or as a court of competent jurisdiction may direct. In carrying out the foregoing, (x) amounts received shall be applied in the numerical order provided until exhausted prior to the application to the next succeeding category, and (y) each of the Persons entitled to receive a payment in any particular category shall receive an amount equal to its pro rata share of amounts available to be applied pursuant thereto for such category.

(b) Agent, or if applicable, each Lender, shall promptly remit to the other Lenders such sums as may be necessary to ensure the ratable repayment of each Lender's portion of any Term Loan and the ratable distribution of interest, fees and reimbursements paid or made by Borrower. Notwithstanding the foregoing, a Lender receiving a scheduled payment shall not be responsible for determining whether the other Lenders also received their scheduled payment on such date; provided, however, if it is determined that a Lender received more than its ratable share of scheduled payments made on any date or dates, then such Lender shall remit to the Agent such sums as may be necessary to ensure the ratable payment of such scheduled payments, as instructed by Agent. If any payment or distribution of any kind or character, whether in cash, properties or securities and whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise, shall be received by a Lender in excess of its ratable share, then (i) the portion of such payment or distribution in excess of such Lender's ratable share shall be received by such Lender in trust for application to the payments of amounts due on the other Lender's claims, or, in the case of Collateral, shall hold such Collateral for itself and as agent and bailee for the Agent and other Lenders and (ii) such Lender shall promptly advise the Agent of the receipt of such payment, and, within five (5) Business Days of such receipt and, in the case of payments and distributions, such Lender shall purchase (for cash at face value) from the other Lenders (through the Agent), without recourse, such participations in the Term Loan made by the other Lenders as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them in accordance with the respective Pro Rata Shares of the Lenders; provided, however, that if all or any portion of such excess payment is thereafter recovered by or on behalf of Borrower from such purchasing Lender, the purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest; provided, further, that the provisions of this Section 9.4(b) shall not be construed to apply to (x) any payment made by Borrower pursuant to and in accordance with the express terms of this Agreement, or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Term Loan pursuant to Section 12.1. Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 9.4(b) may exercise all its rights of payment (including the right of set-off) with


19


respect to such participation as fully as if such Lender were the direct creditor of Borrower in the amount of such participation. No documentation other than notices and the like shall be required to implement the terms of this Section 9.4(b). The Agent shall keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased pursuant to this Section 9.4(b) and shall in each case notify the Lenders following any such purchases.

(c) Notwithstanding anything to the contrary herein, any warrants issued to the Lenders by Borrower, the stock issuable thereunder, any equity securities purchased by Lenders, any amounts paid thereunder, any dividends, and any other rights in connection therewith shall not be subject to the terms and conditions of this Agreement. Nothing herein shall affect any Lender's rights under any such warrants, stock, or other equity securities to administer, manage, transfer, assign, or exercise such warrants, stock, or other equity securities for its own account.

(d) Any reference in this Agreement to an allocation between or sharing by the Lenders of any right, interest or obligation "ratably," "proportionally" or in similar terms shall refer to Pro Rata Share unless expressly provided otherwise.

9.5 Liability for Collateral. So long as Agent and the Lenders comply with reasonable banking practices regarding the safekeeping of the Collateral in the possession or under the control of Agent and the Lenders, Agent and the Lenders shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. Borrower bears all risk of loss, damage or destruction of the Collateral.

9.6 No Waiver; Remedies Cumulative. Agent's failure, at any time or times, to require strict performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Agent thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by Agent and then is only effective for the specific instance and purpose for which it is given. Agent's rights and remedies under this Agreement and the other Loan Documents are cumulative. Agent has all rights and remedies provided under the Code, by Law, or in equity. Agent's exercise of one right or remedy is not an election, and Agent's waiver of any Event of Default is not a continuing waiver. Agent's delay in exercising any remedy is not a waiver, election, or acquiescence.

9.7 Demand Waiver. Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Agent on which Borrower is liable.

NOTWITHSTANDING THE FOREGOING, AGENT AND LENDERS SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH AGENT AND LENDERS (IN ACCORDANCE WITH THE PROVISIONS OF SECTION 9.1) DEEM NECESSARY OR APPROPRIATE TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE AGENT'S AND LENDERS' RIGHTS AGAINST BORROWER OR ITS PROPERTY. BORROWER EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND BORROWER HEREBY WAIVES ANY OBJECTION THAT IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE, OR FORUM NON CONVENIENS AND HEREBY CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH COURT. BORROWER HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINTS, AND OTHER PROCESS ISSUED IN SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINTS, AND OTHER PROCESS MAY BE MADE BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO BORROWER AT THE ADDRESS SET FORTH IN SECTION 10 OF THIS AGREEMENT AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON THE EARLIER TO OCCUR OF BORROWER'S ACTUAL RECEIPT THEREOF OR THREE (3) DAYS AFTER DEPOSIT IN THE U.S. MAILS, PROPER POSTAGE PREPAID.

THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.


21


Borrower, Agent and each Lender agree that each Term Loan (including those made on the Closing Date) shall be deemed to be made in, and the transactions contemplated hereunder and in any other Loan Document shall be deemed to have been performed in, the State of Maryland.


12. GENERAL PROVISIONS

12.1 Successors and Assigns; Additional Lenders; Participations. This Agreement binds and is for the benefit of the successors and permitted assigns of each party. Borrower may not assign this Agreement or any rights or obligations under it without Agent's prior written consent (which may be granted or withheld in Agent's discretion). Subject to the terms and conditions set forth herein, any Lender may at any time assign to one or more Eligible Assignees all or any portion of such Lender's Term Loan, together with all related obligations of such Lender hereunder, with the prior written consent of Borrower (which such consent shall not be unreasonably withheld); provided, however, that no such consent shall be required if the Eligible Assignee is an Approved Fund or an Affiliate of such Lender or if an Event of Default has occurred and is continuing at such time. Borrower and Agent shall be entitled to continue to deal solely and directly with such Lender in connection with the interests so assigned until Agent shall have received and accepted an effective assignment agreement in form and substance acceptable to Agent, executed, delivered and fully completed by the applicable parties thereto, and shall have received such other information regarding such Eligible Assignee as Agent reasonably shall require. Notwithstanding anything set forth in this Agreement to the contrary, any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided, however, that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. Nothing herein shall be interpreted or construed, however, to limit or otherwise restrict the Agent's rights or abilities to assign all of its agency rights hereunder to an Approved Fund or an Affiliate of Agent or add new or additional Lenders after the Closing Date (each an "Additional Lender", and collectively the "Additional Lenders"); provided, however, that any such Additional Lender which is not an Affiliate of Agent or any Lender or is not an Approved Fund, shall, unless an Event of Default has occurred and is continuing at such time, be subject to Borrower's prior written consent (which such consent shall not be unreasonably withheld). Notwithstanding anything to the contrary in this Agreement, Agent and Lenders agree that Agent (in its capacity as a Lender) and Lenders may assign one hundred percent (100%) of the Term Loan Commitments of all Lenders (and in conjunction with such assignment, Agent may assign all of its agency rights hereunder) to an Eligible Assignee, without the consent of Borrower if (i) a majority of the Agent's Life Sciences loan portfolio (which for the avoidance of doubt, the term "majority" as used in this sentence, shall mean more than half of the loans from such Life Sciences loan portfolio) have been sold or assigned to another Person or (ii) the Eligible Assignee is an Approved Fund or an Affiliate of such Lender, or (iii) an Event of Default has occurred and is continuing at such time. Notwithstanding anything set forth in this Agreement to the contrary, any Lender may at any time sell a participation in all or any portion of its rights under this Agreement, to any one or more Persons.

12.2 Indemnification.

(a) Borrower agrees to indemnify, defend and hold Agent and the Lenders and their respective directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Agent or the Lenders (each, an "Indemnified Person") harmless against: (i) all obligations, demands, claims, and liabilities (collectively, "Claims") asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (ii) all losses or Lenders' Expenses incurred, or paid by Indemnified Person from, following, or arising from transactions between Agent, and/or the Lenders and Borrower (including reasonable attorneys' fees and expenses), except for Claims and/or losses directly caused by such Indemnified Person's gross negligence or willful misconduct (collectively, the "Indemnified Liabilities").

(b) Borrower hereby further indemnifies, defends and holds each Indemnified Person harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and disbursements of any kind or nature whatsoever (including the fees and disbursements of counsel for such Indemnitee) in connection with any investigative, response, remedial, administrative or judicial matter or proceeding, whether or not such Indemnified Person shall be designated a party thereto and including any


22


such proceeding initiated by or on behalf of Borrower, and the reasonable expenses of investigation by engineers, environmental consultants and similar technical personnel and any commission, fee or compensation claimed by any broker (other than any broker retained by Agent or Lenders) asserting any right to payment for the transactions contemplated hereby which may be imposed on, incurred by or asserted against such Indemnified Person as a result of or in connection with the transactions contemplated hereby and the use or intended use of the proceeds of the loan proceeds.

(c) To the extent that the undertaking set forth in this Section 12.2 may be unenforceable, Borrower shall contribute the maximum portion which it is permitted to pay and satisfy under applicable law to the payment and satisfaction of all such indemnified liabilities incurred by the Indemnitees or any of them.

12.3 Time of Essence. Time is of the essence for the performance of all Obligations in this Agreement.

12.4 Severability of Provisions. Each provision of this Agreement is severable from every other provision in determining the enforceability of any provision.

12.5 Correction of Loan Documents. Agent and the Lenders may correct patent errors and fill in any blanks in this Agreement and the other Loan Documents consistent with the agreement of the parties.

12.6 Integration. This Agreement and the Loan Documents represent the entire agreement about this subject matter and supersede prior negotiations or agreements. All prior agreements, understandings, representations, warranties, and negotiations between the parties about the subject matter of this Agreement and the Loan Documents merge into this Agreement and the Loan Documents.

12.7 Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, is an original, and all taken together, constitute one Agreement.

12.8 Survival. All covenants, representations and warranties made in this Agreement continue in full force until this Agreement has terminated pursuant to its terms and all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been satisfied. The obligation of Borrower in Section 12.2 to indemnify each Lender and Agent shall survive until the statute of limitations with respect to such claim or cause of action shall have run.

12.9 Confidentiality. In handling any confidential information of Borrower, the Lenders and Agent shall exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (a) to the Lenders' and Agent's Subsidiaries or Affiliates; (b) to prospective transferees or purchasers of any interest in the Credit Extensions (provided, however, the Lenders and Agent shall obtain such prospective transferee's or purchaser's agreement to the terms of this provision); (c) as required by Law, regulation, subpoena, or other order; (d) to regulators or as otherwise required in connection with an examination or audit; (e) as Agent considers appropriate in exercising remedies under the Loan Documents; and (f) to third party service providers of the Lenders and/or Agent so long as such service providers have executed a confidentiality agreement with the Lenders and Agent with terms no less restrictive than those contained herein. Confidential information does not include information that either: (i) is in the public domain or in the Lenders' and/or Agent's possession when disclosed to the Lenders and/or Agent, or becomes part of the public domain after disclosure to the Lenders and/or Agent; or (ii) is disclosed to the Lenders and/or Agent by a third party, if the Lenders and/or Agent does not know that the third party is prohibited from disclosing the information. Agent and/or Lenders may use confidential information for any purpose, including, without limitation, for the development of client databases, reporting purposes, and market analysis, so long as Agent and/or Lenders, as applicable, do not disclose Borrower's identity or the identity of any Person associated with Borrower unless otherwise expressly permitted by this Agreement. The provisions of the immediately preceding sentence shall survive the termination of this Agreement. The agreements provided under this Section 12.9 supersede all prior agreements, understanding, representations, warranties, and negotiations between the parties about the subject matter of this Section 12.9.


23


12.10 Right of Set Off. Borrower hereby grants to Agent and to each Lender, a lien, security interest and right of set off as security for all Obligations to Agent and each Lender hereunder, whether now existing or hereafter arising upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Agent or the Lenders or any entity under the control of Agent or the Lenders (including a Agent affiliate) or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Agent or the Lenders may set off the same or any part thereof and apply the same to any liability or obligation of Borrower even though unmatured and regardless of the adequacy of any other collateral securing the Obligations. ANY AND ALL RIGHTS TO REQUIRE AGENT TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

12.11 [Reserved].

12.12 Amendments.

(a) No amendment, modification, termination or waiver of any provision of this Agreement or any other Loan Document, no approval or consent thereunder, or any consent to any departure by Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by Borrower, Agent and Required Lenders. Except as set forth in clause (b) below, all such amendments, modifications, terminations or waivers requiring the consent of the "Lenders" shall require the written consent of Required Lenders.

(b) No amendment, modification, termination or waiver of any provision of this Agreement or any other Loan Document shall, unless in writing and signed by Agent and each Lender directly affected thereby: (i) increase or decrease the Commitment of any Lender (which shall be deemed to affect all Lenders), (ii) reduce the principal of or rate of interest on any Obligation or the amount of any fees payable hereunder (other than waiving the imposition of the Default Rate), (iii) postpone the date fixed for or waive any payment of principal of or interest on any Term Loan, or any fees or reimbursement obligation hereunder, (iv) release all or substantially all of the Collateral, or consent to a transfer of any of the Intellectual Property, in each case, except as otherwise expressly permitted in the Loan Documents (which shall be deemed to affect all Lenders), (v) subordinate the lien granted in favor of Agent securing the Obligations (which shall be deemed to affect all Lenders), (vi) release a Loan Party from, or consent to a Loan Party's assignment or delegation of, such Loan Party's obligations hereunder and under the other Loan Documents or any Guarantor from its guaranty of the Obligations (which shall be deemed to affect all Lenders) or (vii) amend, modify, terminate or waive Section 9.4, 12.10 or 12.12 or the definition of "Required Lenders" or any other provision hereof specifying the number or percentage of Lenders required to amend, waive or otherwise modify any rights hereunder or make any determination or grant any consent hereunder, without the consent of each Lender.

(c) Notwithstanding any provision in this Section 12.12 to the contrary, no amendment, modification, termination or waiver affecting or modifying the rights or obligations of Agent hereunder shall be effective unless signed by Borrower, Agent and Required Lenders.

Any amendment, modification, supplement, termination, waiver or consent pursuant to this Section 12.12 shall apply equally to, and shall be binding upon, all the Lenders and Agent.

12.13 Publicity. Borrower will not directly or indirectly publish, disclose or otherwise use in any public disclosure, advertising material, promotional material, press release or interview, any reference to the name, logo or any trademark of Agent or any Lender or any of their Affiliates or any reference to this Agreement or the financing evidenced hereby, in any case except as required by applicable Law (including the rules and regulations of the Securities and Exchange Commission), subpoena or judicial or similar order, in which case Borrower shall endeavor to give Agent prior written notice of such publication or other disclosure. Each Lender and Borrower hereby authorizes each Lender to publish the name of such Lender and Borrower, the existence of the financing arrangements referenced under this Agreement, the primary purpose and/or structure of those arrangements, the amount of credit extended under each facility, the title and role of each party to this Agreement, and the total amount of the financing evidenced hereby in any "tombstone", comparable advertisement or press release which such


24


Lender elects to submit for publication. In addition, each Lender and Borrower agrees that each Lender may provide lending industry trade organizations with information necessary and customary for inclusion in league table measurements after the Closing Date. With respect to any of the foregoing, such authorization shall be subject to such Lender providing Borrower and the other Lenders with an opportunity to review and confer with such Lender regarding, and approve, the contents of any such tombstone, advertisement or information, as applicable, prior to its initial submission for publication, but subsequent publications of the same tombstone, advertisement or information shall not require Borrower's approval.

12.14 No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement.


13. AGENT

13.1 Appointment and Authorization of Agent. Each Lender hereby irrevocably appoints, designates and authorizes Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere herein or in any other Loan Document, Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall Agent have or be deemed to have any fiduciary relationship with any Lender or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against Agent. Without limiting the generality of the foregoing sentence, the use of the term "agent" herein and in the other Loan Documents with reference to Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

13.2 Delegation of Duties. Agent may execute any of its duties under this Agreement or any other Loan Document by or through its, or its Affiliates', agents, employees or attorneys-in-fact and shall be entitled to obtain and rely upon the advice of counsel and other consultants or experts concerning all matters pertaining to such duties. Agent shall not be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects in the absence of gross negligence or willful misconduct.

13.3 Liability of Agent. Except as otherwise provided herein, no Agent-Related Person shall (a) be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby (except for its own gross negligence or willful misconduct in connection with its duties expressly set forth herein), or (b) be responsible in any manner to any Lender or participant for any recital, statement, representation or warranty made by Borrower or any officer thereof, contained herein or in any other Loan Document, or in any certificate, report, statement or other document referred to or provided for in, or received by Agent under or in connection with, this Agreement or any other Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document, or for any failure of Borrower or any other party to any Loan Document to perform its obligations hereunder or thereunder. No Agent-Related Person shall be under any obligation to any Lender or participant to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of Borrower or any Affiliate thereof.

13.4 Reliance by Agent. Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone message, electronic mail message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including counsel to Borrower), independent accountants and other experts selected by Agent. Agent shall be fully justified in failing or refusing to take any action under any Loan Document unless it shall first receive such advice or concurrence of all Lenders as it deems appropriate and, if


25


it so requests, it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of all Lenders and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders.

13.5 Notice of Default. Agent shall not be deemed to have knowledge or notice of the occurrence of any Default and/or Event of Default, unless Agent shall have received written notice from a Lender or Borrower, describing such default or Event of Default. Agent will notify the Lenders of its receipt of any such notice. Agent shall take such action with respect to an Event of Default as may be directed in writing by the Required Lenders in accordance with Section 9(a); provided, however, that while an Event of Default has occurred and is continuing, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Event of Default as Agent shall deem advisable or in the best interest of the Lenders, including without limitation, satisfaction of other security interests, liens or encumbrances on the Collateral not permitted under the Loan Documents, payment of taxes on behalf of Borrower, payments to landlords, warehouseman, bailees and other Persons in possession of the Collateral and other actions to protect and safeguard the Collateral, and actions with respect to insurance claims for casualty events affecting Borrower and/or the Collateral.

13.6 Credit Decision; Disclosure of Information by Agent. Each Lender acknowledges that no Agent-Related Person has made any representation or warranty to it, and that no act by Agent hereafter taken, including any consent to and acceptance of any assignment or review of the affairs of Borrower or any Affiliate thereof, shall be deemed to constitute any representation or warranty by any Agent-Related Person to any Lender as to any matter, including whether Agent-Related Persons have disclosed material information in their possession. Each Lender represents to Agent that it has, independently and without reliance upon any Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of, and investigation into, the business, prospects, operations, property, financial and other condition and creditworthiness of Borrower and its respective Subsidiaries, and all applicable bank or other regulatory Laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to Borrower hereunder. Each Lender also represents that it will, independently and without reliance upon any Agent-Related Person and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of Borrower. Except for notices, reports and other documents expressly required to be furnished to the Lenders by Agent herein, Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of Borrower or any of its Affiliates which may come into the possession of any Agent-Related Person.

13.7 Indemnification of Agent. Whether or not the transactions contemplated hereby are consummated, each Lender shall, severally and pro rata based on its respective Pro Rata Share, indemnify upon demand each Agent-Related Person (to the extent not reimbursed by or on behalf of Borrower and without limiting the obligation of Borrower to do so), and hold harmless each Agent-Related Person from and against any and all Indemnified Liabilities (which shall not include legal expenses of Agent incurred in connection with the closing of the transactions contemplated by this Agreement) incurred by it; provided, however, that no Lender shall be liable for the payment to any Agent-Related Person of any portion of such Indemnified Liabilities to the extent determined in a judgment by a court of competent jurisdiction to have resulted from such Agent-Related Person's own gross negligence or willful misconduct; provided, however, that no action taken in accordance with the directions of the Required Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section 13.7. Without limitation of the foregoing, each Lender shall, severally and pro rata based on its respective Pro Rata Share, reimburse Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including Lenders' Expenses incurred after the closing of the transactions contemplated by this Agreement) incurred by Agent (in its capacity as Agent, and not as a Lender) in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to the extent that Agent is not reimbursed for such expenses by or on behalf of Borrower.

After the retiring Agent's resignation hereunder and under the other Loan Documents, the provisions of this Section 13 shall continue in effect for the benefit of such retiring Agent and its sub-agents in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting or was continuing to act as Agent.

13.10 Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to Borrower, Agent (irrespective of whether the principal of any Loan, shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether Agent shall have made any demand on Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

The Lenders irrevocably authorize Agent, at its option and in its discretion, to release any Guarantor and any Lien on any Collateral granted to or held by Agent under any Loan Document (a) upon the date that all Obligations due hereunder have been fully and indefeasibly paid in full and no Term Loan Commitments or other obligations of any Lender to provide funds to Borrower under this Agreement remain outstanding, (b) that is transferred or to be transferred as part of or in connection with any Transfer permitted hereunder or under any other Loan Document, or (c) as approved in accordance with Section 12.11.
