Upon the occurrence and during the continuance of any Event of Default, Agent shall have the right to exercise any and all rights and remedies provided for herein, under the Other Documents, under the Uniform Commercial Code and at law or equity generally, including the right to foreclose the security interests granted herein and to realize upon any Collateral by any available judicial procedure and/or to take possession of and sell any or all of the Collateral with or without judicial process. If reasonably required, Agent may enter any of any Loan Party’s premises or other premises without legal process and without incurring liability to any Loan Party therefor (except for Agent’s gross negligence or willful misconduct), and Agent may thereupon, or at any time thereafter, in its discretion without notice or demand (except for any notice required by Applicable Law), take the Collateral and remove the same to such place as Agent may deem advisable and Agent may require Loan Parties to make the Collateral available

to Agent at a convenient place. With or without having the Collateral at the time or place of sale, Agent may sell the Collateral, or any part thereof, at public or private sale, at any time or place, in one or more sales, at such price or prices, and upon such terms, either for cash, credit or future delivery, as Agent may elect. Agent shall give Loan Parties reasonable notification of such sale or sales, it being agreed that in all events written notice mailed to Borrower at least ten (10) days prior to such sale or sales is reasonable notification. At any public sale Agent or any Lender may bid for and become the purchaser, and Agent, any Lender or any other purchaser at any such sale thereafter shall hold the Collateral sold absolutely free from any claim or right of whatsoever kind, including any equity of redemption and all such claims, rights and equities are hereby expressly waived and released by each Loan Party. The cash proceeds realized from the sale of any Collateral shall be applied to the Obligations in the order set forth in Section 11.5 hereof. Noncash proceeds will only be applied to the Obligations as they are converted into cash. If any deficiency shall arise, Loan Parties shall remain liable to Agent and Lenders therefor.

(b) To the extent that Applicable Law imposes duties on Agent to exercise remedies in a commercially reasonable manner, each Loan Party acknowledges and agrees that it is not commercially unreasonable for Agent (i) to fail to incur expenses reasonably deemed significant by Agent to prepare Collateral for disposition, (ii) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (iii) to fail to exercise collection remedies against any Persons obligated on Collateral or to remove Liens on or any adverse claims against Collateral, (iv) to exercise collection remedies against any Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (v) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (vi) to contact other Persons, whether or not in the same business as any Loan Party, for expressions of interest in acquiring all or any portion of such Collateral, (vii) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (viii) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets, (ix) to dispose of assets in wholesale rather than retail markets, (x) to disclaim disposition warranties, such as title, possession or quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure Agent against risks of loss, collection or disposition of Collateral or to provide to Agent a guaranteed return from the collection or disposition of Collateral, or (xii) to the extent deemed appropriate by Agent, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist Agent in the collection or disposition of any of the Collateral. Each Loan Party acknowledges that the purpose of this Section 11.1(b) is to provide non-exhaustive indications of what actions or omissions by Agent would not be commercially unreasonable in Agent’s exercise of remedies against the Collateral and that other actions or omissions by Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 11.1(b). Without limitation upon the foregoing, nothing contained in this Section 11.1(b) shall be construed to grant any rights to any Loan Party or to impose any duties on Agent that would not have been granted or imposed by this Agreement or by Applicable Law in the absence of this Section 11.1(b).

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

11.3. Setoff. Subject to Section 14.11, in addition to any other rights which Agent or any Lender may have under Applicable Law, upon the occurrence and during the continuance of an Event of Default hereunder, Agent and such Lender shall have a right, immediately and without notice of any kind, to apply any Loan Party’s property held by Agent and such Lender to reduce the Obligations.

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

11.5. Allocation of Payments After Event of Default. Notwithstanding any other provisions of this Agreement to the contrary, after the occurrence and during the continuance of an Event of Default, all amounts collected or received by Agent on account of the Obligations or any other amounts outstanding under any of the Other Documents or in respect of the Collateral may, at Agent’s discretion, be paid over or delivered as follows:

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

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

THIRD, to the payment of all of the Obligations consisting of accrued interest;

FOURTH, to the payment of the outstanding principal amount of the Obligations;

FIFTH, to all other Obligations and other obligations which shall have become due and payable under the Other Documents or otherwise and not repaid pursuant to clauses “FIRST” through “FOURTH” above; and

In carrying out the foregoing, (i) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category; and (ii) each of the Lenders shall receive an amount equal to its pro rata share (based on the proportion that the amount of the then outstanding Term Loan held by such Lender bears to the aggregate then outstanding Term Loan) of amounts available to be applied pursuant to clauses “THIRD”, “FOURTH” and “FIFTH” above.

XII. WAIVERS AND JUDICIAL PROCEEDINGS.

12.1. Waiver of Notice. Each Loan Party hereby waives demand, presentment, protest and notice thereof with respect to any and all instruments, notice of acceptance hereof, notice of loans or advances made, credit extended, Collateral received or delivered, or any other action taken in reliance hereon, and all other demands and notices of any description, except such as are expressly provided for herein.

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

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

XIII. EFFECTIVE DATE AND TERMINATION.

13.1. Term. This Agreement, which shall inure to the benefit of and shall be binding upon the respective successors and permitted assigns of each Loan Party, Agent and each Lender, shall become effective on the Effective Date and shall continue in full force and effect until terminated (which termination shall occur automatically) upon the earlier to occur of (a) payment in full of the Obligations (other than contingent indemnification and reimbursement obligations) and (b) if occurring prior the Conversion Date, initial approval of the application for the Health Registration Approval for the first Stand-Alone Product in the United States.

13.2. Termination and Release. (a) Upon the termination of this Agreement in accordance with its terms, all security interests created under this Agreement and the Other Documents shall be automatically released and Agent shall take all actions reasonably requested by Borrower at Borrower’s expense to evidence the termination of such security interest including without limitation, the filing of UCC-3 financing statements. If such termination and

release occurs on or following the Conversion Date, to the extent that any payments or proceeds previously received by the Agent or any Lender, or any part of such payments, shall be subsequently invalidated, declared to be fraudulent, a fraudulent conveyance, or preferential, set aside and/or required to be repaid to a trustee, receiver, debtor in possession, or any other party under any bankruptcy law, state or federal law, common law or equitable cause, then to the extent that such payment or proceeds received by any such Person is rescinded or must be otherwise restored by any such Person, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, the security interests granted hereunder shall be revived and reinstated and continue in full force and effect, as if such payment or proceeds had never been received by such Person.

(b) Upon the sale or other disposition of any portion of the Collateral in a transaction not prohibited by this Agreement, all security interests created in such portion of the Collateral under this Agreement and the Other Documents shall be automatically released and Agent shall take all actions reasonably requested by Borrower at Borrower’s expense to evidence the termination of such security interest.

XIV. REGARDING AGENT.

14.1. Appointment. Each Lender hereby designates AstraZeneca to act as Agent for such Lender under this Agreement and the Other Documents. Each Lender hereby irrevocably authorizes Agent to take such action on its behalf under the provisions of this Agreement and the Other Documents and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of Agent by the terms hereof and thereof and such other powers as are reasonably incidental thereto and Agent shall hold all Collateral, payments of principal and interest, fees, charges and collections (without giving effect to any collection days) received pursuant to this Agreement, for the ratable benefit of Lenders. Agent may perform any of its duties hereunder by or through its agents or employees. As to any matters not expressly provided for by this Agreement (including collection of the Term Note), Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders, and such instructions shall be binding; provided, however, that Agent shall not be required to take any action which exposes Agent to liability or which is contrary to this Agreement or the Other Documents or Applicable Law unless Agent is furnished with an indemnification reasonably satisfactory to Agent with respect thereto.

14.2. Nature of Duties. Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the Other Documents. Neither Agent nor any of its officers, directors, employees or agents shall be (i) liable for any action taken or omitted by them as such hereunder or in connection herewith, unless caused by their gross (not mere) negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment), or (ii) responsible in any manner for any recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement, or in any of the Other Documents or in any certificate, report, statement or other document referred to or provided for in, or received by Agent under or in connection with, this Agreement or any of the Other Documents or for the value, validity, effectiveness, genuineness, due execution, enforceability or sufficiency of this Agreement, or any of the Other Documents or

for any failure of any Loan Party to perform its obligations hereunder. Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any of the Other Documents, or to inspect the properties, books or records of any Loan Party. The duties of Agent as respects the Term Loan shall be mechanical and administrative in nature; Agent shall not have by reason of this Agreement a fiduciary relationship in respect of any Lender; and nothing in this Agreement, expressed or implied, is intended to or shall be so construed as to impose upon Agent any obligations in respect of this Agreement except as expressly set forth herein.

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

Agent may resign on sixty (60) days’ written notice to each of Lenders and Borrower and upon such resignation, the Required Lenders will promptly designate a successor Agent reasonably satisfactory to Loan Parties.

Any such successor Agent shall succeed to the rights, powers and duties of Agent, and the term “Agent” shall mean such successor agent effective upon its appointment, and the former Agent’s rights, powers and duties as Agent shall be terminated, without any other or further act or deed on the part of such former Agent. After any Agent’s resignation as Agent, the provisions of this Article XIV shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.

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

14.5. Reliance. Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, order or other document or telephone message believed by it to be genuine and correct and to have been signed, sent or made by the proper person or entity. Agent may employ agents and attorneys-in-fact and shall not be liable for the default or misconduct of any such agents or attorneys-in-fact selected by Agent with reasonable care.

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

14.7. Indemnification. To the extent Agent is not reimbursed and indemnified by Loan Parties, each Lender will reimburse and indemnify Agent in proportion to its respective portion of the Term Loan, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against Agent in performing its duties hereunder, or in any way relating to or arising out of this Agreement or any Other Document; provided that, Lenders shall not be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Agent’s gross (not mere) negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment).

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

14.9. Delivery of Documents. To the extent Agent receives financial statements required under Section 9.4 from any Loan Party pursuant to the terms of this Agreement which such Loan Party is not obligated to deliver to each Lender, Agent will promptly furnish such documents and information to Lenders.

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

14.11. Other Agreements. Each of the Lenders agrees that it shall not, without the express consent of Agent, and that it shall, to the extent it is lawfully entitled to do so, upon the request of Agent, set off against the Obligations, any amounts owing by such Lender to any Loan Party or any deposit accounts of any Loan Party now or hereafter maintained with such Lender. Anything in this Agreement to the contrary notwithstanding, each of the Lenders further agrees that it shall not, unless specifically requested to do so by Agent, take any action to protect or enforce its rights arising out of this Agreement or the Other Documents, it being the intent of Lenders that any such action to protect or enforce rights under this Agreement and the Other Documents shall be taken in concert and at the direction or with the consent of Agent or Required Lenders.

XV. MISCELLANEOUS.

15.1. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applied to contracts to be performed wholly within the State of New York. Any judicial proceeding brought by or against any Loan Party with respect to any of the Obligations, this Agreement, the Other Documents or any related agreement may be brought in any court of competent jurisdiction in the State of New York, United States of America, and, by execution and delivery of this Agreement, each Loan Party accepts for itself and in connection with its properties, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts, and irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement. Each Loan Party hereby waives personal service of any and all process upon it and consents that all such service of process may be made by registered mail (return receipt requested) directed to Borrower at its address set forth in Section 15.6 and service so made shall be deemed completed five (5) days after the same shall have been so deposited in the mails of the United States of America, or, at Agent’s option, by service upon Borrower which each Loan Party irrevocably appoints as such Loan Party’s Agent for the purpose of accepting service within the State of New York. Nothing herein shall affect the right to serve process in any manner permitted by law or shall limit the right of Agent or any Lender to bring proceedings against any Loan Party in the courts of any other jurisdiction. Each Loan Party waives any objection to jurisdiction and venue of any action instituted hereunder and shall not assert any defense based on lack of jurisdiction or venue or based upon forum non conveniens. Each Loan Party waives the right to remove any judicial proceeding brought against such Loan Party in any state court to any federal court. Any judicial proceeding by any Loan Party against Agent or any Lender involving, directly or indirectly, any matter or claim in any way arising out of, related to or connected with this Agreement or any related agreement, shall be brought only in a federal or state court located in the County of New York, State of New York.

15.2. Entire Understanding.

(a) This Agreement and the documents executed concurrently herewith contain the entire understanding between each Loan Party, Agent and each Lender and supersedes all prior agreements and understandings, if any, relating to the subject matter hereof. Any promises, representations, warranties or guarantees not herein contained and hereinafter made shall have no force and effect unless in writing, signed by each Loan Party’s, Agent’s and each Lender’s respective officers. Neither this Agreement nor any portion or provisions hereof may be changed, modified, amended, waived, supplemented, discharged, cancelled or terminated orally or by any course of dealing, or in any manner other than by an agreement in writing, signed by the party to be charged. Each Loan Party acknowledges that it has been advised by counsel in connection with the execution of this Agreement and Other Documents and is not relying upon oral representations or statements inconsistent with the terms and provisions of this Agreement.

(b) The Required Lenders, Agent with the consent in writing of the Required Lenders, and Loan Parties may, subject to the provisions of this Section 15.2(b), from time to time enter into written supplemental agreements to this Agreement or the Other Documents executed by Loan Parties, for the purpose of adding or deleting any provisions or otherwise changing, varying or waiving in any manner the rights of Lenders, Agent or Loan Parties thereunder or the conditions, provisions or terms thereof or waiving any Event of Default thereunder, but only to the extent specified in such written agreements; provided, however, that no such supplemental agreement shall, without the consent of all Lenders adversely affected thereby:

(i) extend, with respect to such Lender, the maturity of the Term Note or the due date for any amount payable hereunder, or decrease the rate of interest or reduce any fee payable by Borrower to Lenders pursuant to this Agreement;

(ii) alter the definition of the term Required Lenders or alter, amend or modify this Section 15.2(b);

(iii) release all or substantially all of the Collateral (other than in accordance with the provisions of this Agreement or any Other Document);

(iv) change the rights and duties of Agent; or

(v) release any material Guarantor (other than in accordance with the terms of this Agreement or any Other Document).

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

15.3. Successors and Assigns; New Lenders.

(a) This Agreement shall be binding upon and inure to the benefit of Loan Parties, Agent, each Lender, all future holders of the Obligations and their respective successors and permitted assigns, except that no Loan Party may assign or transfer any of its rights or obligations under this Agreement without the prior written consent of Agent and each Lender.

(b) Any Lender, with the consent of Agent, may sell, assign or transfer all or any part of its rights and obligations under or relating to the Term Loan under this Agreement and the Other Documents to one or more of its Affiliates (each a “Transferee”), pursuant to an assignment agreement substantially in the form attached hereto as Exhibit B (an “Assignment Agreement”) executed by the Transferee, the transferor Lender, and Agent and delivered to Agent for recording. Upon such execution, delivery, acceptance and recording, from and after the transfer effective date determined pursuant to such Assignment Agreement, (i) the Transferee thereunder shall be a party hereto and, to the extent provided in such Assignment Agreement, have the rights and obligations of a Lender thereunder with respect to the portion of the Term Loan set forth therein, and (ii) the transferor Lender thereunder shall, to the extent provided in such Assignment Agreement, be released from its obligations under this Agreement, the Assignment Agreement creating a novation for that purpose. Such Assignment Agreement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Transferee and the resulting adjustment of the Lenders’ proportionate shares of the Term Loan arising from the purchase by such Transferee of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. Each Loan Party hereby consents to the addition of such Transferee and the resulting adjustment of the Lenders’ proportionate shares of the Term Loan arising from the purchase by such Transferee of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. The Loan Parties shall execute and deliver such further documents and do such further acts and things in order to effectuate the foregoing.

(c) Agent shall maintain at its address a copy of each Assignment Agreement delivered to it and a register (the “Register”) for the recordation of the names and addresses of each Lender and the outstanding principal, accrued and unpaid interest and other fees due hereunder. The entries in the Register shall be conclusive, in the absence of manifest error, and each Loan Party, Agent and Lenders may treat each Person whose name is recorded in the Register as the owner of the portion of the Term Loan recorded therein for the purposes of this Agreement. The Register shall be available for inspection by Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Each Loan Party authorizes each Lender to disclose to any Transferee and any prospective Transferee any and all financial information in such Lender’s possession concerning such Loan Party which has been delivered to such Lender by or on behalf of such Loan Party pursuant to this Agreement or in connection with such Lender’s credit evaluation of such Loan Party.

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

15.5. Indemnity. Each Loan Party shall indemnify Agent, each Lender and each of their respective officers, directors, Affiliates, attorneys, employees and agents from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever (including fees and disbursements of counsel) which may be imposed on, incurred by, or asserted against Agent or any Lender in any claim, litigation, proceeding or investigation instituted or conducted by any Governmental Body or instrumentality or any other Person arising out of any breach by any Loan Party of any representation, warranty or covenant in this Agreement or the Other Documents, whether or not Agent or any Lender is a party thereto, except, with respect to any indemnitee, for claims resulting from the gross negligence or willful misconduct of such indemnitee or any of its respective officers, directors, Affiliates, attorneys, employees and agents, as determined by final judgment of a court of competent jurisdiction.

15.6. Notice. Any notice or request hereunder may be given to Borrower or any Loan Party or to Agent or any Lender at their respective addresses set forth below or at such other address as may hereafter be specified in a notice designated as a notice of change of address under this Section 15.6. Any notice, request, demand, direction or other communication (for purposes of this Section 15.6 only, a “Notice”) to be given to or made upon any party hereto under any provision of this Agreement shall be given or made by telephone or in writing (which includes by means of facsimile transmission). Any such Notice must be delivered to the applicable parties hereto at the addresses and numbers set forth under their respective names on Section 15.6 hereof or in accordance with any subsequent unrevoked Notice from any such party that is given in accordance with this Section 15.6. Any Notice shall be effective:

(b) If given by mail, four (4) days after such Notice is deposited with the United States Postal Service, with first-class postage prepaid, return receipt requested;

(c) In the case of a telephonic Notice, when a party is contacted by telephone, if delivery of such telephonic Notice is confirmed no later than the next Business Day by hand delivery, a facsimile transmission or an overnight courier delivery of a confirmatory Notice (received at or before noon on such next Business Day);

15.7. Survival. The obligations of Loan Parties under Section 15.5 and the obligations of Lenders under Section 14.7 shall survive termination of this Agreement and the Other Documents and payment in full of the Obligations.

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

15.9. Expenses. All costs and expenses including reasonable attorneys’ fees and disbursements incurred by Agent on its behalf or on behalf of Lenders in all efforts made to enforce payment of any Obligation or effect collection of any Collateral shall be part of the Obligations.

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

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

15.13. Counterparts; Facsimile Signatures. This Agreement may be executed in any number of and by different parties hereto on separate counterparts, all of which, when so executed, shall be deemed an original, but all such counterparts shall constitute one and the same agreement. Any signature delivered by a party by facsimile transmission or email transmission of a .pdf or similar file shall be deemed to be an original signature hereto.

15.14. Construction. The parties acknowledge that each party and its counsel have reviewed this Agreement and that the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Agreement or any amendments, schedules or exhibits thereto.

XVI. GUARANTY.

16.1. Guaranty. Each Guarantor hereby unconditionally guarantees, as a primary obligor and not merely as a surety, jointly and severally with each other Guarantor when and as due, whether at maturity, by acceleration, or otherwise, the due and punctual payment and performance of all Obligations of Borrower. Each payment made by any Guarantor pursuant to this Guaranty shall be made in lawful money of the United States in immediately available funds.

16.2. Waivers. Each Guarantor hereby absolutely, unconditionally and irrevocably waives (i) promptness, diligence, notice of acceptance, notice of presentment of payment and any other notice hereunder, (ii) demand of payment, protest, notice of dishonor or nonpayment, notice of the present and future amount of the Obligations and any other notice with respect to the Obligations, (iii) any requirement that Agent or any Lender protect, secure, perfect or insure any security interest or Lien on any property subject thereto or exhaust any right or take any action against any other Loan Party, or any Person or any Collateral, (iv) any other action, event or precondition to the enforcement hereof or the performance by each such Guarantor of the Obligations, and (v) any defense arising by any lack of capacity or authority or any other defense of any Loan Party or any notice, demand or defense by reason of cessation from any cause of Obligations other than payment in full of the Obligations (other than contingent indemnification or reimbursement obligations) by the Loan Parties and any defense that any other guarantee or security was or was to be obtained by Agent.

16.3. No Defense. No invalidity, irregularity, voidableness, voidness or unenforceability of this Agreement or any Other Document or any other agreement or instrument relating thereto, or of all or any part of the Obligations or of any collateral security therefor shall affect, impair or be a defense hereunder.

16.4. Guaranty of Payment. The Guaranty hereunder is one of payment and performance, not collection, and the obligations of each Guarantor hereunder are independent of the Obligations of the other Loan Parties, and a separate action or actions may be brought and prosecuted against any Guarantor to enforce the terms and conditions of this Article XVI, irrespective of whether any action is brought against any other Loan Party or other Persons or whether any other Loan Party or other Persons are joined in any such action or actions. Each Guarantor waives any right to require that any resort be had by Agent or any Lender to any security held for payment of the Obligations or to any balance of any deposit account or credit on the books of Agent or any Lender in favor of any Loan Party or any other Person. No election to proceed in one form of action or proceedings, or against any Person, or on any Obligations, shall constitute a waiver of Agent’s right to proceed in any other form of action or proceeding or against any other Person unless Agent has expressed any such right in writing. Without limiting the generality of the foregoing, no action or proceeding by Agent against any Loan Party under any document evidencing or securing indebtedness of any Loan Party to Agent shall diminish the liability of any Guarantor hereunder, except to the extent Agent receives actual payment on account of Obligations by such action or proceeding, notwithstanding the effect of any such election, action or proceeding upon the right of subrogation of any Guarantor in respect of any Loan Party.

16.5. Liabilities Absolute. The liability of each Guarantor hereunder shall be absolute, unlimited and unconditional and shall not be subject to any reduction, limitation, impairment, discharge or termination for any reason other than payment in full of the Obligations, including, without limitation, any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any claim, defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of any other Obligation or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor shall not be discharged or impaired, released, limited or otherwise affected by:

(i) any change in the manner, place or terms of payment or performance, and/or any change or extension of the time of payment or performance of, release, renewal or alteration of, or any new agreements relating to any Obligation, any security therefor, or any liability incurred directly or indirectly in respect thereof, or any rescission of, or amendment, waiver or other modification of, or any consent to departure from, this Agreement or any Other Document, including any increase in the Obligations resulting from the extension of additional credit to Borrower or otherwise;

(ii) any sale, exchange, release, surrender, loss, abandonment, realization upon any property by whomsoever at any time pledged or mortgaged to secure, or howsoever securing, all or any of the Obligations, and/or any offset there against, or failure to perfect, or continue the perfection of, any Lien in any such property, or delay in the perfection of any such Lien, or any amendment or waiver of or consent to departure from any other guaranty for all or any of the Obligations;

(iii) the failure of Agent or any Lender to assert any claim or demand or to enforce any right or remedy against Borrower or any other Loan Party or any other Person under the provisions of this Agreement or any Other Document or any other document or instrument executed and delivered in connection herewith or therewith;

(b) Agent shall not be required to marshal any assets in favor of any Guarantor, or against or in payment of Obligations.

(c) No Guarantor shall be entitled to claim against any present or future security held by Agent from any Person for Obligations in priority to or equally with any claim of Agent, or assert any claim for any liability of any Loan Party to any Guarantor in priority to or equally with claims of Agent for Obligations, and no Guarantor shall be entitled to compete with Agent with respect to, or to advance any equal or prior claim to any security held by Agent for Obligations.

(d) If any Loan Party makes any payment to Agent, which payment is wholly or partly subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to any Person under any federal or provincial statute or at common law or under equitable principles, then to the extent of such payment, the Obligation intended to be paid shall be revived and continued in full force and effect as if the payment had not been made, and the resulting revived Obligation shall continue to be guaranteed, uninterrupted, by each Guarantor hereunder.

(e) All present and future monies payable by any Loan Party to any Guarantor, whether arising out of a right of subrogation or otherwise, are assigned to Agent for its benefit and for the ratable benefit of Lenders as security for such Guarantor’s liability to Agent and Lenders hereunder and are postponed and subordinated to Agent’s prior right to payment in full of Obligations. Except to the extent prohibited otherwise by this Agreement, all monies received by any Guarantor from any Loan Party shall be held by such Guarantor as agent and trustee for Agent. This assignment, postponement and subordination shall only terminate when the Obligations are paid in full and this Agreement is terminated.

(f) Each Loan Party acknowledges this assignment, postponement and subordination and, except as otherwise set forth herein, agrees to make no payments to any Guarantor without the prior written consent of Agent. Each Loan Party agrees to give full effect to the provisions hereof.

16.9. Limit. Each Guarantor and each of Agent and each Lender (by its acceptable of the benefits of this Agreement) hereby confirms that it is its intention that the guaranty made by the Guarantors not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act or similar Federal or state law. To effectuate the foregoing intention, each Guarantor and each of Agent and each Lender (by its acceptable of the benefits of this Agreement) hereby irrevocably agrees that the Obligations guaranteed by such Guarantor shall be limited to such amount as will, after giving effect to such maximum amount and all other (contingent or otherwise) liabilities of such Guarantor that are relevant under such laws, not constitute a fraudulent transfer or conveyance for purposes of such laws.

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