If such judgement is finally reversed by an unappealable decree of a court of competent jurisdiction of higher dignity in such country, or is deemed reversed as provided herein, the former royalty rates shall be restored and the royalty payments not theretofore made, together with the interest that TRIANGLE might reasonably have earned (based on immediately available deposits) on the payments withheld, shall become due and payable to ARROW. If such judgement is not reversed, deemed reversed, is unappealed or becomes unappealable, as aforesaid, TRIANGLE shall be entitled to all of the royalty reductions pursuant to this Section 6.13. This Section 6.13 shall only be applicable to royalties which TRIANGLE and its AFFILIATES and SUB LICENSEES are paying in respect of PRODUCTS covered by Subsection 6.5.1(a). 6.14 ARROW shall have the right, upon prior notice to TRIANGLE, not more than once in each TRIANGLE fiscal year nor more than once in respect of any fiscal year, through - ---------- *** Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission. an independent certified public accountant selected by ARROW and acceptable to TRIANGLE, which acceptance shall not be unreasonably refused, to have access during normal business hours to those records of TRIANGLE as may be reasonably necessary to verify the accuracy of the royalty reports required to be furnished by TRIANGLE pursuant to this Article 6. TRIANGLE shall include in any sublicenses granted pursuant to this AGREEMENT a provision requiring the SUB-LICENSEE to keep and maintain records of sales made pursuant to such sublicense and to grant access to such records by ARROW's independent certified public accountant. If such independent certified public accountant's report shows any underpayment of royalties by TRIANGLE or its AFFILIATES or SUB-LICENSEES, within thirty (30) days after TRIANGLE'S receipt of such report, TRIANGLE shall remit or cause its SUB-LICENSEES to remit to ARROW the amount of such underpayment together with interest, compounded quarterly, calculated on the amount underpaid at the rate of *** % per month; and if such underpayment exceeds *** percent ( *** %) of the total royalties owed for the fiscal year then being reviewed, the reasonably necessary fees and expenses of such independent certified public accounting performing the audit. Otherwise, ARROW's accountant's fees and expenses shall be borne by ARROW. Any overpayment of royalties shall be fully creditable against future royalties payable in any subsequent royalty periods. Upon the expiration of *** months following the end of any fiscal year, the calculation of royalties payable with respect to such fiscal year shall be binding and conclusive on ARROW and TRIANGLE, unless an audit for such fiscal year is initiated before expiration of such *** months. 6.15 All information subject to review under this Article 6 shall be confidential.

ARTICLE 7. DEVELOPMENT PROGRAMME 7.1 Subject to ARROW'S timely performance of its obligations hereunder, and in complete fulfilment of TRIANGLE'S development obligations hereunder and any such obligations implied by law, TRIANGLE will undertake, or will cause its AFFILIATES or SUB-LICENSEES to undertake, the development activities described in this Article 7. TRIANGLE shall, *** , use its best efforts to conduct a development program (the "DEVELOPMENT PROGRAMME") in the U.S. relating to the use of at least one PRODUCT containing a given ARROW SELECTED COMPOUND and to seek REGISTRATION for such PRODUCT in at least one MAJOR MARKET COUNTRY. The DEVELOPMENT PROGRAMME shall be mutually discussed by the parties hereto and shall take into consideration studies and experiments carried out, or to be carried out by, ARROW, but the activities comprising the DEVELOPMENT PROGRAMME shall be determined at TRIANGLE'S sole discretion. Anything in this AGREEMENT to the contrary notwithstanding, TRIANGLE shall be entitled to exercise prudent and justifiable business judgement in meeting its best efforts obligations hereunder. For purposes of this Article 7, "best efforts" shall mean that TRIANGLE shall use reasonable efforts consistent with those used by it in its development projects with other compounds in its development portfolio deemed to have comparable commercial potential. - ---------- *** Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission. 7.2 Subject to the foregoing provisions of this Article 7, TRIANGLE'S best efforts obligations set forth in this Article 7 shall be deemed to have been satisfied if TRIANGLE: (a) files an IND in a MAJOR MARKET COUNTRY for the first PRODUCT containing a given ARROW SELECTED COMPOUND within *** months after the date on which such ARROW SELECTED COMPOUND has been selected as a candidate for the DEVELOPMENT PROGRAMME by the JOINT STEERING COMMITTEE. (b) files in at least one MAJOR MARKET COUNTRY what it reasonably believes to be a complete NDA for such PRODUCT with the appropriate regulatory agency within *** months after the ARROW SELECTED COMPOUND contained in such PRODUCT is selected for the DEVELOPMENT PROGRAMME by the JOINT STEERING COMMITTEE. The time periods set forth in clauses (a) and (b) shall each be subject to up to *** extensions of *** each at TRIANGLE'S election by payment to ARROW of a sum of *** Dollars ($ *** ) for each such *** extension. 7.3 (a) In the event TRIANGLE fails to meet any diligence requirements set forth in Section 7.2(a) or 7.2(b) with respect to a given PRODUCT, and does not demonstrate to ARROW's reasonable satisfaction that, despite TRIANGLE'S efforts, the failure to meet the diligence requirements was delayed due to reasons beyond TRIANGLE'S reasonable control, ARROW shall have the option, at its sole and exclusive remedy, to terminate the AGREEMENT in the entire TERRITORY with respect only to such PRODUCT. (b) Prior to exercising any rights under this Section 7.3, ARROW shall give - ---------- *** Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission. TRIANGLE *** notice and shall meet with TRIANGLE in London, at TRIANGLE'S request, during such *** period, to discuss any disagreements about whether TRIANGLE has complied with the applicable diligence requirements of this Article 7. Upon expiration of such *** period, ARROW shall have the right in its sole discretion to proceed with the exercise of all rights and remedies provided for herein unless the applicable diligence requirement is fulfilled during such *** period. (c) Upon termination by ARROW of this AGREEMENT pursuant to this Section 7.3, the provisions of Article 14.2 shall apply in respect of such PRODUCT. ARTICLE 8. JOINT STEERING COMMITTEE 8.1 Prior to the EFFECTIVE DATE, ARROW and TRIANGLE have each appointed an authorized representative (a "Coordinator"). In the case of ARROW, the Coordinator is Jeremy Stables and in the case of TRIANGLE, the Coordinator is Merrick Almond. Each Coordinator shall be responsible for communications, other than legal notices, between the parties with respect to the subject matter of this AGREEMENT. Each party may replace its Coordinator at any time for any or no reason by providing written notice to the other party. 8.2 The Coordinators shall establish the JOINT STEERING COMMITTEE consisting of equal numbers of representatives of TRIANGLE and ARROW. The JOINT STEERING COMMITTEE will consist of at least three (3) persons from each of TRIANGLE and ARROW, such persons having significant responsibility for the development and/or marketing of the PRODUCTS. The JOINT STEERING COMMITTEE will meet from time to time at mutually agreeable times via teleconference or in-person, but no less than quarterly during the term of the AGREEMENT. The Coordinators shall set the agenda for each meeting, and each Coordinator shall determine which regular members of the JOINT STEERING COMMITTEE and other representatives of such Coordinator's party shall attend in light of the agenda. Each party shall bear its own costs incurred in - ---------- *** Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission. connection with participation in the JOINT STEERING COMMITTEE. 8.3 The primary objective of the JOINT STEERING COMMITTEE will be to facilitate the expeditious development and REGISTRATION of PRODUCTS by, inter alia: (a) facilitating the exchange of data and study results between the parties; (b) providing a forum for protocol and development plan review; (c) coordinating the developmental efforts of the parties so as to avoid duplication and inconsistency of such efforts; (d) coordinating the manufacturing of, and controls relating to, all PRODUCTS during the DEVELOPMENT PROGRAMME; and (e) reviewing the regulatory plans and timelines relating to the PRODUCTS. Each party agrees to give due consideration to any input received from the other party at such JOINT STEERING COMMITTEE meetings; provided, however, that, in the event of disagreement, all final decisions relating to (x) the research of the ARROW- SOURCED COMPOUNDS will be made by ARROW, and (y) the research and development of SELECTED COMPOUNDS and/or TRIANGLE-SOURCED COMPOUNDS and the PRODUCTS in the TERRITORY will be made by TRIANGLE. 8.4 Each party shall submit a report detailing the results of each study or test which it performs to the other party within forty-five (45) days after completion of the final statistical analyses of the results of such study. In addition, each party will provide the other party with semi-annual progress reports summarizing its activities in respect of the development of PRODUCTS during the relevant semi-annual period. Such reports shall cover the semi-annual periods ending each June 30 and December 31 and shall be due on or before July 15 and January 15 of each year, respectively. 8.5 Each party reserves the right to publish or publicly present the results of its own development activities in respect of the PRODUCTS (the "Results"). The party proposing to publish or publicly present the Results (the "publishing party") will, however, submit a draft of any proposed manuscript, abstract, speech, transparencies, presentation materials and press releases to the other party (the "non-publishing party") for comments at least: (a) twenty (20) days prior to submission for publication or oral presentation in the case of full manuscripts; (b) five (5) days prior to submission for publication or oral presentation in the case of abstracts; and (c) two (2) days prior to publication in the case of press releases, except, in the case of press releases, where applicable law, in the reasonable opinion of the publishing party, requires such press release to be issued within time constraints which would make such review impractical. The non-publishing party shall notify the publishing party in writing within the applicable time period set forth above after receipt of such draft whether such draft contains Information (as hereinafter defined) of the non-publishing party which it considers to be confidential under the provisions of Article 9 hereof, or information that if published would have an adverse effect on a patent application for which the non-publishing party has initial patent prosecution responsibility pursuant to Article 4 of this Agreement. In the latter case, the non-publishing party shall have the right to request a delay and the publishing party shall delay such publication for a period not exceeding sixty (60) days. In any such notification, the non-publishing party shall indicate with specificity its suggestions regarding the manner and degree to which the publishing party may disclose such information. The publishing party shall have the final authority to determine the scope and content of any publication, provided that such authority shall be exercised with reasonable regard for the interests of the non-publishing party, except that no publication will contain any Information disclosed by the non-publishing party to the publishing party without the non-publishing party's prior written permission. Each party shall cause its Affiliates, licensees or sublicensees, as the case may be, to comply with the requirements of this Section 8.5 with respect to any of their proposed publications. ARTICLE 9. CONFIDENTIALITY 9.1 During the term of this AGREEMENT and for a period of *** years thereafter: 9.1.1 TRIANGLE, its AFFILIATES and SUB-LICENSEES will retain in confidence and use only for purposes of this AGREEMENT any INFORMATION supplied by ARROW or on behalf of ARROW to TRIANGLE under this AGREEMENT; and 9.1.2 ARROW will retain in confidence and use only for purposes of this AGREEMENT, INFORMATION supplied by TRIANGLE or on behalf of TRIANGLE to ARROW under this AGREEMENT. 9.2 To the extent it is reasonably necessary or appropriate to fulfill its obligations or exercise its rights under this AGREEMENT, a party may disclose INFORMATION received from the other party to its AFFILIATES and/or sub-licensees (prospective or actual), consultants, outside contractors and clinical investigators on condition that such entities or persons agree (i) to keep the INFORMATION confidential for at least *** years from the date of disclosure and to the same extent as such party is required to keep the INFORMATION confidential and (ii) to use the INFORMATION only for such purposes as such party is entitled to use the INFORMATION. TRIANGLE or its AFFILIATES and SUB-LICENSEES and ARROW may disclose such INFORMATION to government or other regulatory authorities to the extent that such disclosure is reasonably necessary to obtain patents or authorisations to conduct clinical trials with and to commercially market the PRODUCT. In the case of government or other regulatory authorities the Recipient shall wherever possible provide the Disclosing Party with reasonable notice of such disclosures and to whom such disclosures are being made. 9.3 The foregoing obligations in respect of confidentiality and use shall not apply to - ---------- *** Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission. any part of INFORMATION disclosed by one party (the "Disclosing Party") to another (the "Recipient") which: (a) is in the public domain at the time of disclosure or thereafter becomes part of the public domain through no fault of the Recipient or of a person to whom the Recipient made a disclosure in accordance with Section 9.2; (b) is in the possession of the Recipient at the time of disclosure and was not acquired on a confidential basis from the Disclosing Party; (c) is received by the Recipient from a third party having the right to disclose the same; (d) is developed by the Recipient totally independent from any disclosures hereunder; (e) the Disclosing Party agrees may be disclosed to third parties under secrecy agreement containing the same restrictions as in this AGREEMENT; or (f) the Recipient is required to disclose to a court or governmental agency or pursuant to subpoena or other compulsory process. 9.4 In the event that a party is required by a court or governmental agency or pursuant to subpoena or other compulsory process (excluding disclosures made to patent office) to disclose the Disclosing Party's INFORMATION other than as authorised herein, it shall use reasonable efforts to obtain a protective order or otherwise protect the confidentiality of such INFORMATION. In no event, however, shall such party's disclosure of such INFORMATION to a court, governmental agency, or other non-authorised party pursuant to a subpoena or other compulsory process, be regarded as making such INFORMATION publicly known, available by publication or in the public domain or otherwise permit any further or subsequent disclosure of such INFORMATION by such party. For purposes of this Section 9.4 "third party" shall mean any party other than TRIANGLE and ARROW. 9.5 Except to the extent otherwise required by applicable law or regulation or the terms of this AGREEMENT or mutually agreed upon in good faith by the parties hereto, each party shall treat as confidential the financial terms and conditions contained in this AGREEMENT; provided, however, that each party may disclose the terms of this Agreement in confidence to its consultants, financial, legal and other advisors and prospective investors and sublicensees.

In the event that during the term of this AGREEMENT, ARROW becomes debarred or receives notice of an action or threat of an action with respect to its debarment, ARROW shall notify TRIANGLE immediately.

Neither party shall have any authority to enter into any contracts or assume any obligations for the other party nor make any warranties or representations on behalf of that other party. 20.4 This AGREEMENT sets forth the entire agreement and final understanding between the parties hereto as to the subject matter hereof, and neither of the parties shall be bound by any conditions, definitions, warranties, understandings or representations with respect to such subject matter other than as expressly provided herein or as duly set forth subsequent to the date hereof in writing signed by a proper and duly authorised officer or representative of the relevant party. 20.5 Neither party shall be held liable or responsible to the other party nor be deemed to have defaulted under or breached this AGREEMENT for failure or delay in fulfilling or performing any provision of this AGREEMENT, when such failure or delay is caused by or results from fire, floods, embargoes, government regulations (including regulatory holds), prohibitions or interventions, war, acts of war (whether war is declared or not), insurrections, riots, civil commotions, strikes, acts of God, or any other cause beyond the reasonable control of the affected party. 20.6 Each party agrees to give the other party prompt written notice of the occurrence of any such condition set forth in Section 20.5 above, the nature thereof, and the extent to which the affected party will be unable fully to perform its obligations hereunder. Each party further agrees to use all reasonable efforts to correct the condition as quickly as possible, and to give the other prompt written notice when it is again fully able to perform such obligations. If, as a result of conditions set forth in Section 20.5 above, either party is unable fully to perform its obligations hereunder for any consecutive period of three hundred and sixty-five (365) days, the other party shall have the right to terminate this AGREEMENT upon written notice. 20.7 Both parties hereby expressly agree and contract that it is the intention of neither party to violate any public policy, statutory or common laws, rules, regulations, treaty or decision of any government agency or executive body thereof of any country or community or association of countries; that if any word, sentence, paragraph, clause or combination thereof of this AGREEMENT is found, by a court or executive body with judicial powers having jurisdiction over this AGREEMENT or any of the parties hereto, in a final unappealed order, to be in violation of any such provisions in any country or community or association of countries, such words, sentences, paragraphs, clauses or combination shall be inoperative in such country or community or association of countries and the remainder of this AGREEMENT shall remain binding upon the parties hereto. 20.8 The failure of a party to enforce at any time for any period any of the provisions hereof shall not be construed as a waiver of such provisions or of the rights of such party thereafter to enforce each such provision. 20.9 The parties agree to issue mutual press releases concerning their entry into this Agreement, with the content of such releases to be approved (which consent shall not be unreasonably withheld or delayed) in advance by the parties. In all other respects, except as required by law, neither party shall use the name of the other party in any publicity release without the prior written permission of such other party, which shall not be unreasonably withheld. The other party shall have a reasonable opportunity to review and comment on any such proposed publicity release. Except as required by law, neither party shall publicly disclose the terms of this Agreement or issue any publicity release with regard thereto unless expressly authorised to do so by the other party which authorisation shall be agreed upon. 20.10 This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
