THE ACQUISITION NOTE

SECTION 2.01 Acquisition Note.

(a) Issuance of Acquisition Note. So long as no Default or Event of Default has occurred and is continuing, InterMune agrees, on the terms and conditions hereinafter set forth, to accept on the Closing Date the Acquisition Note, representing a loan from InterMune to Purchaser in the amount of the first Acquisition Installment Payment, which amount shall be changed as each additional Acquisition Installment Payment becomes due and payable under the Asset Purchase Agreement.

(b) Acquisition Note. Purchaser shall execute and deliver to InterMune the promissory note in substantially the form of Exhibit A (the “Acquisition Note”) on the Closing Date, as evidence of the obligations of Purchaser to make the Acquisition Installment Payments to InterMune under the Asset Purchase Agreement, such Acquisition Note to be automatically amended to increase or decrease the principal amount outstanding thereunder from time to time to reflect Acquisition Installment Payments under the Asset Purchase Agreement and conversions of principal into New Equity Shares upon the occurrence of the Preferred Equity Financing or thereafter (subject to the Ownership Limitation).

(c) Effect of Event of Default. Upon the occurrence of an Event of Default prior to the occurrence of the First Milestone (as defined in the Asset Purchase Agreement) or the Second Milestone (as defined in the Asset Purchase Agreement), only the portion of the principal amount of the Acquisition Note that is then outstanding (that is, without taking into account the Acquisition Installment Payments that would become due on the occurrence of the First Milestone or Second Milestone, as the case may be) shall become due and payable, as set forth in Article 6 hereof. Notwithstanding the occurrence of an Event of Default, Purchaser shall be obligated to make the Acquisition Installment Payments upon the First Milestone or Second Milestone, as applicable, to the extent such payments have not yet been made.

(d) Conversion of Acquisition Note. The Acquisition Note shall be converted into shares of Purchaser’s capital stock in connection with a Preferred Equity Financing or Subsequent Equity Financing, as the case may be, in accordance with the terms and conditions

set forth in Section 9 of such Acquisition Note. Upon the closing of any Equity Financing (as defined in the Acquisition Note) pursuant to which any portion of the principal amount of the Acquisition Note is converted into preferred stock of the Purchaser, InterMune shall be a party to any purchase agreement entered in connection with such Equity Financing and Purchaser’s counsel shall include InterMune as an addressee in the opinion delivered to the other investors in such Equity Financing. So long as Purchaser may be required, under the Asset Purchase Agreement, to make Acquisition Installment Payments, the Acquisition Note shall remain outstanding, notwithstanding all amounts owing under the Acquisition Note having been converted into shares of Purchaser’s capital stock in accordance with Section 9 of the Acquisition Note. As provided in Section 9 of the Acquisition Note, if Purchaser, prior to the maturity date of the Acquisition Note, completes the Preferred Equity Financing or a Subsequent Equity Financing, the maximum amount of principal under the Acquisition Note as may, subject to the Ownership Limitation, be converted into New Equity Shares or Subsequent Equity Shares, as the case may be, shall automatically be converted into such equity securities. In the event that InterMune’s equity ownership in Purchaser inadvertently exceeds the Ownership Limitation, including without limitation as a result of repurchases or redemptions of equity securities by Purchaser, then (i) that number of equity securities resulting in InterMune’s equity ownership exceeding the Ownership Limitation shall be automatically be cancelled (the “Violating Shares”) and (ii) the principal amount of the Acquisition Note shall automatically be increased by an amount equal to the product of (x) the number of Violating Shares and (y) the Per Share Price (as defined in the Acquisition Note) at which such Violating Shares were originally issued upon conversion thereunder.

(e) Treatment in Connection with a Liquidity Event. Absent acceleration after an Event of Default, at any time, if there shall be a Liquidity Event, then the balance outstanding under the Acquisition Note as of the closing of the Liquidity Event shall be (i) automatically converted into the most recently issued series of preferred stock of Purchaser at the conversion price such shares were originally sold to unrelated third parties, subject to the Ownership Limitation, (ii) due and payable in cash or (iii) assumed by the successor entity in connection with such Liquidity Event, as more fully set forth in Section 10 of the Acquisition Note.

SECTION 2.02 Interest.

(a) No Interest Payments Absent Acceleration. Except as set forth in this Section 2.02, no interest shall accrue and no interest payments shall be due under the Acquisition Note.

(b) Default Rate of Interest. In the event of an Event of Default, which Event of Default shall not have been cured in the applicable cure period, if any, from the date of the Event of Default until such Event of Default has been cured or, if such Event of Default cannot be cured, until all Obligations have been paid in full, Purchaser shall pay interest on the unpaid principal of the Acquisition Note at a rate per annum equal at all times to the lesser of (i) 8%, and (ii) the highest lawful rate. Anything herein to the contrary notwithstanding, if during any period for which interest is computed hereunder, the applicable interest rate, together with all fees, charges and other payments which are treated as interest under applicable law, as provided for herein or in any other Acquisition Document, would exceed the maximum rate of interest

which may be charged, contracted for, reserved, received or collected by InterMune in connection with this Agreement under applicable law (the “Maximum Rate”), Purchaser shall not be obligated to pay, and InterMune shall not be entitled to charge, collect, receive, reserve or take, interest in excess of the Maximum Rate, and during any such period the interest payable hereunder shall be limited to the Maximum Rate.

(c) Computations. All computations of interest hereunder shall be made on the basis of a year of 365 or 366 days, as the case may be, for the actual number of days occurring in the period for which any such interest is payable.

SECTION 2.03 General Provisions Regarding Payments.

(a) Unconditional Obligation. Purchaser shall make each payment under this Agreement, the Acquisition Note and each payment on account of the purchase price of the Purchased Assets under the Asset Purchase Agreement, unconditionally in full without set-off, counterclaim or, to the extent permitted by applicable law, other defense (except to the extent otherwise permitted by the Asset Purchase Agreement). Each payment shall be made not later than 11:00 a.m. (San Francisco time) on the day when due to InterMune in Dollars and in same day funds, or such other funds as shall be separately agreed upon by Purchaser and InterMune, in accordance with InterMune’s payment instructions.

(b) Extension. Whenever any payment hereunder shall be stated to be due, or whenever any interest payment date or any other date specified hereunder would otherwise occur, on a day other than a Business Day, then, except as otherwise provided herein, such payment shall be made, and such interest payment date or other date shall occur, on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest.

SECTION 2.04 No Prepayments of the Acquisition Note. Purchaser may not pre-pay all or any portion of the Acquisition Note.

SECTION 2.05 Waiver of Presentment, Etc. Unless otherwise expressly provided herein, Purchaser waives presentment, and notice of demand or dishonor and protest as to any instrument, notice of intent to accelerate the payment Obligations and notice of acceleration of the payment Obligations, as well as any and all other notices to which it might otherwise be entitled. No notice to or demand on Purchaser that InterMune may elect to give shall entitle Purchaser to any or further notice or demand in the same, similar or other circumstances.

Each notice pursuant to clauses (i) through (iii) of this subsection (c) shall be accompanied by a written statement by a Responsible Officer of Purchaser setting forth details of the occurrence referred to therein.

SECTION 5.02 Affirmative Covenants. So long as any of the Obligations shall remain unpaid or outstanding or Purchaser may be required, under the Asset Purchase Agreement, to make Acquisition Installment Payments, Purchaser agrees that:

(a) Preservation of Existence, Etc.

(i) Purchaser will, and will cause each of its Subsidiaries to, maintain and preserve its corporate existence.

(ii) Purchaser will, and will cause each of its Subsidiaries to, use commercially reasonable efforts to maintain and preserve its rights to transact business and all other rights, Permits and privileges necessary in the normal course of its business and operations and the ownership of its properties, except in connection with any transactions expressly permitted by this Agreement, or where the failure to so maintain or preserve such rights, Permits and privileges would not result in a Material Adverse Effect. Notwithstanding the foregoing, this covenant will not be breached by the fact that Purchaser has not yet obtained a license to sell pharmaceutical products in California (or any jurisdiction where the same may be necessary or desirable) so long as Purchaser uses its best efforts to diligently obtain such license or licenses, and the lack of the same does not cause a Material Adverse Effect.

(b) Payment of Taxes, Etc. Purchaser will, and will cause each of its Subsidiaries to, use commercially reasonable efforts to pay and discharge all taxes, fees, assessments and governmental charges or levies imposed upon it or upon its properties or assets prior to the date on which penalties attach thereto, and all lawful claims for labor, materials and supplies which, if unpaid, might become a Lien upon any properties or assets of Purchaser or any Subsidiary, except to the extent such taxes, fees, assessments or governmental charges or levies, or such claims, are being contested in good faith by appropriate proceedings and are adequately reserved against in accordance with GAAP.

(c) Maintenance of Insurance. Purchaser will, and will cause each of its Subsidiaries to, use commercially reasonable efforts to carry and maintain in full force and

effect, at its own expense and with financially sound and reputable insurance companies, insurance in such amounts, with such deductibles and covering such risks as, in the good faith belief of Purchaser, is customarily appropriate for companies engaged in similar businesses and owning similar properties in the localities where Purchaser or such Subsidiary operates. Insurance on the Collateral shall name InterMune as an additional insured and as a loss payee. Upon the request of InterMune, Purchaser shall furnish InterMune from time to time with full information as to the insurance carried by it and, if so reasonably requested, copies of all such insurance policies. Purchaser shall also furnish to InterMune, from time to time upon its reasonable request, a certificate of Purchaser’s insurance broker or other insurance specialist stating that all premiums then due on the policies relating to Purchaser’s insurance have been paid and that such policies are in full force and effect.

Purchaser will, and will cause each of its Subsidiaries to, use commercially reasonable efforts to obtain and maintain all licenses, authorizations, consents, filings, exemptions, registrations and other governmental approvals of any governmental agency or authority necessary in connection with the execution, delivery and performance of the Acquisition Documents, the consummation of the transactions therein contemplated or the operation and conduct of its business and ownership of its properties.

Purchaser shall not surrender or lose possession of (other than (i) to InterMune, (ii) related to sales or other dispositions of inventory in the ordinary course of business or (iii) by transfer of the custody thereof in the ordinary course of business to a third party contracted by Purchaser to store any portion of the Collateral), sell, lease, rent, or otherwise dispose of or transfer any of the Collateral or any right or interest therein, except as otherwise permitted by this Agreement.

(g) Affiliate Security Agreement. In the event Purchaser transfers any of the assets or rights relating to or constituting the Products or any Collateral to any Affiliate of Purchaser (subject to the terms and conditions of this Agreement), then within two Business

Days of such transfer, Purchaser shall cause to be delivered to InterMune a security agreement (relating to the Collateral transferred to such Affiliate) and a guaranty of the Obligations duly executed by such Affiliate and otherwise in form and substance satisfactory to InterMune and shall cause such Affiliate to have executed and filed any UCC-1 financing statements furnished by InterMune in each jurisdiction in which such filing is necessary to perfect the security interest of InterMune in the Collateral of such Affiliate and in which InterMune requests that such filing be made. Additionally, Purchaser and such Affiliate shall have executed and delivered to InterMune such other items as reasonably requested by InterMune in connection with the foregoing, including resolutions, search reports and other certificates and documents.

(i) Composition of Board of Directors. Purchaser shall cause the Board of Directors of Purchaser to include one member designated by InterMune.

(j) Preferred Equity Financing. Purchaser shall cause the closing of the Preferred Equity Financing to occur no later than one hundred and twenty (120) days following achievement of the First Milestone by Purchaser (the “Cut Off Date”); provided that if, at the Cut Off Date, the Purchaser is in good faith negotiations with a lead investor regarding the terms of a Preferred Equity Financing but Purchaser is not yet ready to close such Preferred Equity Financing, Purchaser shall cause the closing of such Preferred Equity Financing to occur as soon as practicable following the Cut Off Date, but in any event no longer than sixty (60) days following the Cut Off Date.

(k) Additional Security Documents. As promptly as practicable after the Closing Date, and in no event more than thirty (30) days after the Closing Date, Purchaser will cause each of the Ontario Subsidiary and the Quebec Subsidiary to (i) enter into, execute and deliver a guarantee of the Obligations, and a security agreement or hypothec, as applicable, pursuant to which each of them shall, as security for the payment and performance of the Obligations, pledge, assign, transfer, hypothecate and grant a first priority security interest and lien in all of such entity’s right, title and interest in, to and under the Collateral (as defined in the Security Agreement) and (ii) take any and all other actions reasonably requested by InterMune for the attachment, perfection and priority of and the ability of InterMune to enforce InterMune’s security interest in any and all of the Collateral.

(i) fail to make any payment of any principal of, or interest or premium on, any Indebtedness (other than in respect of the Acquisition Note) in an aggregate principal amount outstanding of at least $500,000 (or its equivalent in another currency) when due (whether by scheduled maturity, required prepayment, acceleration, demand or otherwise) and such failure shall continue after the applicable grace period, if any, specified in the agreement or instrument relating to such Indebtedness as of the date of such failure, provided that so long as such Indebtedness or the non-payment thereof is being diligently contested in good faith by Purchaser, no Event of Default shall be triggered unless the party claiming that Purchaser has defaulted exercises some right or remedy or takes some action that would otherwise be a Default or Event of Default under any of the Acquisition Documents; or

(ii) have any Indebtedness in an aggregate principal amount outstanding of at least $500,000 be declared to be immediately due and payable, or required to be prepaid (other than by a regularly scheduled required prepayment) prior to the stated maturity thereof.

(h) Judgments.

(i) final, non-appealable judgment or order for the payment of money, where the portion payable by Purchaser (or any Subsidiary) and not a third-party insurance carrier is in excess of $1,000,000 shall be rendered against Purchaser or any of its Subsidiaries (or its equivalent in another currency); or

(ii) any non-monetary judgment or court order shall be rendered against Purchaser or any Subsidiary that has or could be reasonably expected to have a Material Adverse Effect;

and in each case there shall be any period of thirty (30) consecutive days during which such judgment continues unsatisfied or during which a stay of enforcement of such judgment or order, by reason of a pending appeal or otherwise, shall not be in effect.

(i) Collateral Documents. It shall be an immediate Event of Default hereunder and not susceptible of cure should any of the Collateral Documents after delivery thereof for any reason be revoked or invalidated, or otherwise cease to be in full force and effect (other than due to an action or inaction that was solely the fault of InterMune, and not the consequence of some other default or breach of Purchaser under any of the Acquisition Documents), or Purchaser or any other Person shall contest in any manner the validity or enforceability thereof, or Purchaser or any other Person shall deny that it has any further liability or obligation thereunder; or any of the Collateral Documents for any reason, except to the extent permitted by the terms thereof, shall cease to create a valid and perfected first priority Lien subject only to Permitted Liens in any of the Collateral purported to be covered thereby (other than due to an action or inaction that was solely the fault of InterMune, and not the consequence of some other default or breach of Purchaser under any of the Acquisition Documents).

(j) Violation of Regulations, Etc. Notwithstanding anything to the contrary in this Agreement, and despite any representation, warranty and covenant to the contrary set forth herein or in the other Acquisition Documents or the Disclosure Letter, in the event that Purchaser

(i) is in material violation of any law, rule, regulation, order, judgment, decree or the like reasonably expected to be binding on or affecting Purchaser;

(ii) lacks any authorization, consent, approval, license, exemption of, or filing or registration with, any governmental agency or authority that is material to the Purchaser, or

(iii) lacks any material Permits, free from burdensome restrictions, that are necessary for the ownership, maintenance or operation of Purchaser’s business,

then so long as any of the same, (A) if known on the Closing Date, have been disclosed in the Disclosure Letter, and/or (B) if not known on the Closing Date, are promptly disclosed to InterMune once Purchaser has notice thereof, Purchaser shall have 120 days from the date Purchaser learns (or should have learned) that the foregoing events have caused or can reasonably be expected to cause a Material Adverse Effect within which to effectuate a cure and reverse the Material Adverse Effect, thereby postponing the occurrence of an Event of Default until such 120th day (if no cure is effected), notwithstanding that Purchaser may be in breach of the covenants contained in any of Sections 5.02(a)(ii) and/or 5.02(e) or any similar covenants relating to the matters referred to in subsections (i), (ii), or (iii) of this Section 6.01(j).

(k) Amendment of Investor Convertible Notes. It shall be an immediate Event of Default if the Investor Convertible Notes are amended in a manner that materially and adversely affects InterMune, except if InterMune shall have consented in advance and in writing to such amendment.

SECTION 6.02 Effect of Event of Default. If any Event of Default shall occur, InterMune may (i) by notice to Purchaser, (A) declare its commitment to accept the Acquisition Note in place of the Acquisition Installment Payments to be terminated, upon which declaration such commitment to accept the Acquisition Note shall forthwith terminate, and/or (B) declare the entire unpaid outstanding principal amount of the Acquisition Note and all interest accrued and unpaid on the foregoing and all other Obligations to be forthwith due and payable, whereupon the Acquisition Note and all such accrued interest shall become and be forthwith due and payable, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by Purchaser; provided that if an event described in Section 6.01(f) or (g) shall occur, the result of which would otherwise occur only upon giving of notice by InterMune to Purchaser as specified in this clause (i) shall occur automatically, without the giving of any such notice; and (ii) whether or not the actions referred to in clause (i) have been taken, (A) exercise any or all of InterMune’s rights and remedies under the Collateral Documents, and (B) proceed to enforce all other rights and remedies available to InterMune under the Acquisition Documents and applicable law; and provided, further, that if an Event of Default occurs because of a breach of the covenant set forth in Section 5.02(j) and InterMune elects to exercise its rights to the Collateral under Section 6 the Security Agreement, all obligations, whether outstanding or potentially arising in the future, owed to InterMune by Purchaser under the Acquisition Note shall immediately be released and terminated.

ARTICLE VII

MISCELLANEOUS

SECTION 7.01 Amendments and Waivers. No amendment to any provision of the Acquisition Documents shall be effective unless it is in writing and has been signed by InterMune and Purchaser, and no waiver of any provision of any Acquisition Document, or consent to any departure by Purchaser therefrom, shall be effective unless it is in writing and has been signed by InterMune. Any such amendment, waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

SECTION 7.02 Notices. All notices and other communications provided for hereunder and under the other Acquisition Documents shall, unless otherwise stated herein, be in writing (including by facsimile transmission) and mailed, sent or delivered to the respective parties hereto at or to their respective addresses or facsimile numbers set forth below their names on the signature pages hereof, or at or to such other address or facsimile number as shall be designated by any party in a written notice to the other party hereto. All such notices and communications shall be effective (i) if delivered by hand, when delivered; (ii) if sent by mail, upon the earlier of the date of receipt or five Business Days after deposit in the mail, first class, postage prepaid; and (iii) if sent by facsimile transmission, when sent; provided, however, that notices and communications to InterMune pursuant to Article II shall not be effective until received.

SECTION 7.03 No Waiver; Cumulative Remedies. No failure on the part of InterMune to exercise, and no delay in exercising, any right, remedy, power or privilege under any Acquisition Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, remedy, power or privilege preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights and remedies under the Acquisition Documents are cumulative and not exclusive of any rights, remedies, powers and privileges that may otherwise be available to InterMune.

SECTION 7.04 Costs and Expenses; Indemnity.

(a) Costs and Expenses. Purchaser agrees to pay on demand all costs and expenses of InterMune and its Affiliates, and fees and disbursements of counsel, in connection with (A) any Default, (B) the enforcement or attempted enforcement of, and preservation of any rights or interests under, the Acquisition Documents (excluding the Asset Purchase Agreement because the cost and expense provisions contained therein shall govern the Asset Purchase Agreement), and (C) any out-of-court workout or other refinancing or restructuring or any bankruptcy or insolvency case or proceeding.

(b) Treatment of Tax Liabilities. Each of InterMune and Purchaser shall be responsible for paying its own sales, use, transfer and value added and other related taxes, if any, relating to this Agreement.

(c) Indemnification. Purchaser shall indemnify, reimburse, defend and hold harmless InterMune, its Affiliates and their respective officers, directors, employees, agents, successors and assigns (each an “Indemnified Person”) from and against any and all Damages (as defined in the Asset Purchase Agreement) on the terms set forth in the Asset Purchase Agreement, under which Purchaser shall be considered “Buyer” and InterMune shall be considered “Seller.”

SECTION 7.05 Currency. The United States dollar is the currency of account and payment for each and every sum at any time due from Purchaser hereunder provided that each payment in respect of costs and expenses or Taxes shall be made in the currency in which the same were incurred.

SECTION 7.06 Survival. All covenants, agreements, representations and warranties made in any Acquisition Documents (excluding the Asset Purchase Agreement which shall not be governed or limited by this provision) shall, except to the extent otherwise provided therein, survive the execution and delivery of this Agreement, the acceptance by InterMune of the Acquisition Note and the execution and delivery of the Acquisition Note, and shall continue in full force and effect so long as InterMune has any commitment to accept the Acquisition Note in place of any Acquisition Installment Payment from Purchaser, the Acquisition Note remains outstanding or any other Obligations remain unpaid or any obligation to perform any other act hereunder or under any other Acquisition Document remains unsatisfied. Without limiting the generality of the foregoing, the obligations of Purchaser under Section 7.04, and all similar obligations under the other Acquisition Documents (including all obligations to pay costs and expenses and all indemnity obligations, excluding the Asset Purchase Agreement which shall not be governed or limited by this provision), and all confidentiality obligations shall survive the repayment of the Acquisition Note and the termination of the commitment or InterMune to accept the Acquisition Note in place of any Acquisition Installment Payment.

SECTION 7.07 Benefits of Agreement. The Acquisition Documents are entered into for the sole protection and benefit of the parties hereto and thereto and their successors and assigns, and no other Person shall be a direct or indirect beneficiary of, or shall have any direct or indirect cause of action or claim in connection with, any Acquisition Document.

SECTION 7.08 Binding Effect; Assignment. This Agreement shall become effective when it shall have been executed by Purchaser and InterMune and thereafter shall be binding upon, inure to the benefit of and be enforceable by Purchaser, InterMune and their respective successors and assigns. Purchaser shall not have the right to assign its rights and obligations hereunder or under the other Acquisition Documents or any interest herein or therein without the prior written consent of InterMune, which consent shall not be unreasonably withheld, other than the assignment in connection with a Liquidity Event of an obligation to issue an Acquisition Note. Any such purported assignment, transfer, hypothecation or other conveyance by Purchaser without the prior express written consent of InterMune shall be void. InterMune reserves the right to sell, assign, transfer or grant participations in all or any portion of InterMune’s rights and obligations hereunder and under the other Acquisition Documents to any other Person in accordance with Section 4.02(b). In the event of any such sale, assignment, transfer or grant (including of participation interests) by InterMune in accordance with Section 4.02(b) hereof, the assignee shall be deemed “InterMune” for all purposes of the Acquisition Documents with respect to the rights and obligations assigned to it, and the obligations of InterMune so assigned shall thereupon terminate. Purchaser shall, from time to time upon request of InterMune, enter into such amendments to the Acquisition Documents and execute and deliver such other documents as shall be necessary to effect any such sale, assignment, transfer or grant (including of participation interests). Purchaser agrees that in connection with any such sale, assignment, transfer or grant (including of participation interests), InterMune may deliver to the prospective participant, assignee, purchaser, transferee or grantee financial statements and other relevant information relating to Purchaser and its Subsidiaries. InterMune shall obtain from any such prospective participant, assignee, purchaser, transferee or grantee a confidentiality agreement in which such participant or assignee agrees to an obligation of confidentiality substantially similar to the terms of Section 7.09 of this Agreement and Section 12.01 of the Asset Purchase Agreement.

SECTION 7.09 Confidentiality.

(a) In addition to the restrictions contained in Section 7.12 of this Agreement, after the Closing Date no party to this Agreement (a “Disclosing Party”) shall, without the prior written consent of the other Party (the “Non-disclosing Party”), disclose to any Person and Confidential Information (as defined below) of the Non-disclosing party, except to a Disclosing Party’s employees or representatives who need to know such information in connection with the transactions contemplated hereby (and then only to the extent that such persons are under an obligation to maintain the confidentiality of the Confidential Information) or use any Confidential Information of the Non-disclosing Party for any reason other than contemplated by this Agreement unless such Disclosing Party has used its best efforts to (i) consult with the Non-disclosing Party and obtain the Non-disclosing Party’s prior written consent in a timely manner, and (ii) the Disclosing Party has been advised by counsel that disclosure is required to be made under applicable law or the requirements of a national securities exchange or another similar regulatory body. In the event that the Disclosing Party is requested or required by documents

subpoena, civil investigative demand, interrogatories, requests for information, or other similar process to disclose any Confidential Information, the Disclosing Party shall provide the Non-disclosing Party with prompt notice of such request or demands or other similar process so that the Non-disclosing Party may seek an appropriate protective order or, if such request, demand or other similar process is mandatory, waive the Disclosing Party’s compliance with the provisions of this Section 7.09(a) as appropriate.

(b) The term “Confidential Information” as used in this Section 7.09 means (i) as to Purchaser, the provisions and terms of this Agreement and the other Acquisition Documents, as well as all confidential information relating to Purchaser’s business, and the Purchased Assets, and the Assumed Liabilities (as defined in the Asset Purchase Agreement), and (ii) as to InterMune, the provisions and terms of this Agreement and the other Acquisition Documents, all confidential information relating to the Business (as defined in the Asset Purchase Agreement) other than information related solely to the business and operations of InterMune and its Affiliates, including the Excluded Assets and the Excluded Liabilities (as those terms are defined in the Asset Purchase Agreement) or other obligations other than the Assumed Liabilities, in each of (i) and (ii) whether disclosed prior to or after the date hereof. The term “Confidential Information” does not include information that becomes generally available to the public other than as a result of disclosure by the Disclosing Party, or becomes available to the Disclosing Party on a non-confidential basis from a source other than the Non-disclosing Party, provided that such source is not bound by a confidentiality agreement with the Non-disclosing Party.

SECTION 7.10 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE APPLICABLE TO CONTRACTS EXECUTED AND PERFORMED IN SUCH STATE, WITHOUT GIVING EFFECT TO CONFLICTS OF LAWS PRINCIPLES.

SECTION 7.11 Public Announcements. Neither Purchaser, InterMune nor any of their respective Affiliates shall issue any press release or make any public announcement with respect to this Agreement and the transactions contemplated hereby without obtaining the prior written consent of the other party, which consent shall not be unreasonably withheld, except as may be required by applicable law upon the advice of counsel and only if the disclosing Party provides the non-disclosing Party with an opportunity to first review the release or other public announcement.

SECTION 7.12 Entire Agreement. The Acquisition Documents reflect the entire agreement between Purchaser and InterMune with respect to the matters set forth herein and therein and supersede any prior agreements, commitments, drafts, communication, discussions and understandings, oral or written, with respect thereto.

SECTION 7.13 Severability. Whenever possible, each provision of the Acquisition Documents shall be interpreted in such manner as to be effective and valid under all applicable laws and regulations. If, however, any provision of any of the Acquisition Documents shall be prohibited by or invalid under any such law or regulation in any jurisdiction, it shall, as to such jurisdiction, be deemed modified to conform to the minimum requirements of such law or regulation, or, if for any reason it is not deemed so modified, it shall be ineffective and invalid only to the extent of such prohibition or invalidity without affecting the remaining provisions of such Acquisition Document, or the validity or effectiveness of such provision in any other jurisdiction.

SECTION 7.14 Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute but one and the same agreement.
