5.04 Royalties. Subject to the terms and conditions of this Agreement, PII shall pay to RBX a royalty in the amount of [*] percent ([*]%) of Net Sales of each Licensed Product in the Territory commencing with the First Commercial Sale of the first Licensed Product.

5.05 Royalty Period. PII’s obligation to pay royalties to RBX under Section 5.04 shall apply on a Licensed Product-by-Licensed Product basis and shall begin, on a country by country basis, upon the date of the First Commercial Sale in such country of such Licensed Product and shall end upon termination of sale of the Licensed Product in such country.

5.06 Payments to Third Parties. In the event PPD determines that it is necessary or desirable to seek a license or immunity from suit from any Third Party in order for PPD to exercise its rights hereunder to Develop, manufacture, commercialize, use or exploit the Compound or a Licensed Product in a particular country of the Territory, PPD shall obtain any such license or immunity from suit. Any upfront payment, milestone, royalty or other payment paid or payable by PPD to a Third Party in consideration for immunity from or license to such Third Party’s intellectual property rights with respect to the Compound or a Licensed Product shall be solely for PPD’s account and RBX shall have no liability (including, without limitation, any indemnity obligation) for any such amounts.

5.07 Method of Calculation. The calculation of the amount of royalties due under the provisions of Section 5.04 shall be subject to and computed in accordance with the following provisions:

(a) Frequency. Royalties shall be calculated and paid on a calendar quarter basis. PII shall provide RBX with a statement of royalties owed to RBX within thirty (30) days after the end of each calendar quarter and the quarterly royalty payment shall be made at the time of such statement. Each of the quarterly statement of royalties and the annual statement provided in the following sentence shall show in reasonably specific detail, on a country-by-country basis (i) the total number of units of each of the Licensed Products sold, (ii) the Net Sales on a Licensed Product-by-Licensed Product basis (including the detailed calculation of the deductions from gross sales of each of the Licensed Products in arriving at Net Sales); (iii) the calculation of the royalties payable pursuant to Section 5.04 in United States dollars which had been accrued hereunder based upon Net Sales of each Licensed Product, including a detailed calculation showing the application of the applicable royalty rates under Section 5.04 to the aggregate Net Sales for all Licensed Products; (iv) the withholding taxes, if any, required by law to be deducted with respect to such royalties and the amounts paid to the appropriate governmental authority with respect to such royalties; (v) the date of the first Commercial Sale of each Licensed Product in each country in the Territory during the reporting period; and (vi) the exchange rates used in determining the amount of United States dollars. In addition, at the end of each calendar year, aggregate royalties for such calendar year shall be calculated on aggregate Net Sales for all Licensed Products for such calendar year to determine additional royalty payments owed to RBX by PII. Within sixty (60) days after the end of each calendar year, PII shall provide RBX with a statement of such additional aggregate royalty payments owed to RBX and a written report showing the method by which the royalty payments for such calendar year were calculated, including a breakdown of gross sales and Net Sales for each Licensed Product sold, including any exchange rates used. If there are no sales of Licensed Product in a country in a given year,

[*]	Confidential treatment requested; certain information omitted and filed separately with the SEC.

then no statement for such country shall be included in such yearly report. PII shall submit any additional aggregate royalty payments to RBX together with such statement and written report. With respect to sales of any Licensed Products invoiced in United States dollars, the Net Sales and royalties and other payments payable hereunder shall be expressed in United States Dollars. With respect to sales of any Licensed Products invoiced in a currency other than United States Dollars, the Net Sales and royalties and other payments payable hereunder with respect to such Licensed Products shall be expressed in the domestic currency of the party making the sale together with the United States dollar equivalent of the royalty payment payable, and such exchange rate shall be calculated pursuant to Section 6.03.

(b) Combination Products. PII shall pay RBX royalties on Net Sales of any Combination Product. For the purpose of calculating royalties on Net Sales of Combination Products hereunder, Net Sales of a Combination Product shall be determined on a country by country basis by multiplying the actual Net Sales of the Combination Product by the fraction A/(A+B), where A is the average sale price of a Licensed Product in a given country when sold separately in finished form and B is the average sale price of the other product(s) comprising the active ingredients other than the Compound sold separately in finished form in that given country. With respect to Net Sales of Combination Products outside of the United States, where available in a given country, the most recent reference price(s) or government-regulated price(s) for the other product(s) in the given country will be used as the average sale price. In the event that such average sale price cannot be determined for either the Licensed Product or other product(s) in the Combination Product, Net Sales for purposes of determining royalty payments hereunder shall be calculated by multiplying the Net Sales of the Combination Product by the fraction C/(C+D), where C is PII’s, or its Affiliates’, sublicensees’ or Third Party Partner’s cost of goods of the Licensed Product and D is PII’s, or its Affiliates’, sublicensees’ or Third Party Partner’s cost of goods of the other product(s), in each case determined in accordance with GAAP.

(c) Royalty and Patents. Regardless of the number of patents that cover a Licensed Product, only one royalty shall be payable upon sale of a Licensed Product.

(d) Other Consideration. In the case of a sale or other disposal of Licensed Product for value other than in an arm’s-length transaction exclusively for money, such as barter or counter-trade, the amount of such sale shall be calculated using the fair market value of such Licensed Product (if higher than the stated sales price) in the country of disposition.

ARTICLE VI – Royalty Records, Verification and Payment

6.01 Books and Records. PII shall keep and shall require any Affiliates, sublicensees and Third Party Partner selling any Licensed Product to keep proper records and books of account, in accordance with GAAP, showing the Net Sales of each Licensed Product upon which the royalty payments and Sales Milestone Payments of PII are based, and all other information necessary for the accurate determination of royalty payments to be made hereunder.

6.02 Audit. On reasonable written notice RBX, at its own expense, shall have the right, no more than once a calendar year, to have an independent certified public accountant inspect and

audit the books and records of PII, its Affiliates, any sublicensees and Third Party Partner, including any Net Sales reports received from its Affiliates, its sublicensees and its Third Party Partner, during usual business hours for the sole purpose of, and only to the extent necessary for, determining the correctness of royalty payments due under this Agreement. Such examination with respect to any fiscal period shall not take place later than three years following the expiration of such period, after which royalty payments made for such fiscal periods shall be final and binding. The expense of any such audit shall be borne by RBX; provided, however, that, if the audit with respect to a particular calendar year discloses an error in excess of five percent (5%) in favor of the PII, then PII shall pay, in addition to the amount of any underpayment, the cost of the audit. PII shall include substantially the same audit rights in any sublicense it grants in order to ensure correctness of payments due hereunder.

6.03 Foreign Payments. All payments due hereunder shall be paid in U.S. dollars, including, without limitation, royalties on Net Sales outside of the U.S. Dollar amounts shall be calculated in the foreign currency for the country in which sales are recorded and will be translated into U.S. dollars based on the average of the average daily exchange rates for such calendar quarter as published by the Wall Street Journal for the quarter for which such payments are due. Payments in U.S. dollars shall be paid by wire transfer to RBX.

The previous sentence shall not apply to any decision of PII that is based on its determination, in its sole discretion, that the value of a particular PII invention will most likely be maximized by a form of intellectual property protection other than patent protection, or that a particular filing would detract from the overall value of the patent estate.

(c) [*] shall be responsible for all patent costs (including filing fees, maintenance fees, and outside attorney fees) with respect to each Patent within the RBX Patents and Joint Patents that covers the composition of matter, manufacture or use of the Compound.

7.04 Notification. PII shall provide a written report to RBX every second calendar quarter summarizing the status of all RBX Patents and Joint Patents. Such report shall constitute Confidential Information under Article IX.

PII shall have the first right to take whatever action it deems appropriate to enforce the RBX Patents, Joint Patents or PII Patents, at its sole cost and expense. If PII does not, within sixty (60) days of receipt of such notice of alleged infringement take any action, or file any suit to enforce the RBX Patents, Joint Patents and PII Patents against such infringing party in a country in the Territory, RBX may in its discretion, take such action as it deems appropriate, including, without limitation, filing suit against any such infringing party. If RBX elects to enforce the RBX Patents, RBX shall use good faith efforts in any such proceeding against infringers, shall consult with PII during said enforcement and shall solicit PII’s advice with respect to such enforcement. Regardless of which Party controls any such enforcement action, RBX and PII shall reasonably cooperate with each other in the planning and execution of any action to enforce the RBX Patents, Joint Patents and PII Patents. The Party controlling any such enforcement action may not settle or consent to an adverse judgment without the express written consent of the non-controlling Party (such consent not to be unreasonably withheld or delayed). Any damages or other amounts collected with respect to such action will first be used to reimburse each of the Parties, on a pro rata basis, for its out of pocket costs and expenses; and then, any remaining amount will be distributed [*]% to the Party controlling the enforcement action and [*]% to the other Party.

The execution, delivery and performance of this Agreement have been duly authorized by all necessary action on the part of PII, its officers and directors.

ARTICLE XI – TERM AND TERMINATION

11.01 Term. Unless otherwise terminated in accordance with the provisions of this Article XI, the licenses granted herein and the obligations assumed hereunder shall commence as of the Option Exercise Date and shall expire on a country-by-country and Licensed Product-by-Licensed Product basis (the Parties agreeing that each Licensed Product shall have its own term) upon the later to occur of (i) ten (10) years from the First Commercial Sale in such country of such Licensed Product, and (ii) the expiry of the last to expire Enforceable Claim covering such Licensed Product in such country. In the event PII does not exercise the Option prior to the expiration of the Option Period, subject to Section 11.05, this Agreement shall terminate and be of no further legal force or effect.

11.02 Material Breach. This Agreement may be terminated by either Party upon the material default of this Agreement by the other Party. In the event of such material default by a Party (“Defaulting Party”), the other Party (“Non-Defaulting Party”) shall give the Defaulting Party written notice of the default and its election to terminate this Agreement at the expiration of a cure period of twenty (20) days for payment default and thirty (30) days for non-payment defaults from the date of the notice. If the Defaulting Party fails to cure the default within the applicable grace period, or if such default is incapable of being cured within such grace period (expressly excluding payment defaults) and the Defaulting Party has failed within such period to take actions that are reasonably likely to cure such default, provided that in no event shall such default continue beyond one hundred fifty (150) days, then the Non-Defaulting Party may terminate this Agreement by giving written notice to the Defaulting Party. The termination will be effective upon Defaulting Party’s receipt of such termination notice. All termination rights shall be in addition to and not in substitution for any other remedies that may be available to the Non-Defaulting Party. Termination pursuant to this section will not relieve the Defaulting Party from liability and damages to the Non-Defaulting Party for default. Waiver by either Party of a single default or a succession of defaults will not deprive such Party of any right to terminate this Agreement arising by reason of any subsequent default. Notwithstanding the foregoing, PII shall not be considered in material default under this Agreement if such material default results from a Licensed Product Manufacturing Failure.

11.03 Termination for Failure to Meet Key Development Milestones. RBX may terminate this Agreement upon thirty (30) days’ written notice to PII in the event that any one or more of the following milestones have not been achieved within six (6) months of the date corresponding to such milestone as follows:


	Milestone	Date

1.	IND Submission	July, 2008

2.	First Dosing in a Phase I Clinical Study for a Licensed Product	September, 2009

3.	First Dosing in a Phase II Clinical Study for a Licensed Product	July, 2012

4.	First Dosing in a Phase III Clinical Study	Within two (2) years of receiving written meeting minutes from the End of Phase II FDA meeting for the first Licensed Product

5.	Filing of NDA with FDA for a Licensed Product	Within two (2) years of receiving written meeting minutes from the Pre-NDA FDA meeting for the first Licensed Product

6.	First Commercial Sale of such Licensed Product in the U.S.	Within two (2) years of receipt of written notification of US Regulatory Approval by the FDA for the first Licensed Product

provided; however, that the period within which a milestone must be achieved as provided above, and each subsequent milestone thereafter, will be extended to the extent of the delay in the completion of the applicable milestone that was caused by (i) RBX’s delay in compliance with its obligations provided in Sections 4.05 and 4.07 of this Agreement, (ii) a Force Majeure event or (iii) an Interfering Event. PII shall use Diligent Efforts to achieve each of the Milestones provided above as soon as practicable and shall, in the event of a delay, provide RBX detailed information on a monthly basis describing the reason for the delay, the actions being taken to overcome the delay and the estimated time to complete the delayed Milestone.

11.04 Termination for Insolvency/Bankruptcy. It either PII or RBX (i) makes a general assignment for the benefit or creditors or becomes insolvent; (ii) files an insolvency petition in bankruptcy; (iii) petitions for or acquiesces in the appointment of any receiver, trustee or similar officer to liquidate or conserve its business or a substantial part of its assets; (iv) commences under the laws of any jurisdiction any proceeding involving its insolvency, bankruptcy, reorganization, adjustment of debt, dissolution, liquidation or any other similar proceedings for the release of financially distressed debtors; or (v) becomes a party to any proceeding or action of the type described in (iii) or (iv) and such proceeding or action remains undismissed or unstayed for a period of more than sixty (60) days, then the other party may by written notice terminate this Agreement in its entirety with immediate effect.

11.05 Voluntary Termination by PII. PII shall have the right to terminate this Agreement in the course of Development upon giving RBX at least sixty (60) days prior written notice, if PII, in its sole discretion, determines that further Development or commercialization of Licensed Product is no longer viable for safety, efficacy or manufacturing reasons, or, if in the opinion of PII, the Licensed Product is no longer viable for commercial reasons. In such event, PII shall, to the extent it is legally required to do so, diligently finalize any clinical trial it has initiated and issue the corresponding final report and any other pertinent documents (including providing copies of same to RBX) in compliance with applicable regulatory requirements. In the event PII exercises the right of termination provided in this Section 11.05 prior to the completion of any

[*] Confidential treatment requested; certain information omitted and filed separately with the SEC.

Phase II Clinical Study for the Licensed Product other than (i) for safety, or efficacy reasons relating to the Licensed Product, (ii) for a material Licensed Product Manufacturing Failure, or (iii) for breach of this Agreement by RBX, within thirty (30) days of the provision of PII’s written notice of termination to Ranbaxy as provided in this Section 11.05, PII shall remit to Ranbaxy a termination payment of one million dollars ($1,000,000).

(e) PII shall be deemed to have automatically conveyed to RBX (without any further action required by PPD) all of PII’s, its Affiliates’ and its Third Party Partner’s right, title and interest in and to any and all Regulatory Approvals (including related Regulatory Documentation) then pending or otherwise obtained by PII, its Affiliates or its Third Party Partner relating to the Compound or any Licensed Product(s);

11.08 Residual Obligation upon Termination. Termination of this Agreement for any reason whatsoever will not release or discharge the Parties from the performance of any obligation, the payment of any debt or responsibility for any liability which may have previously accrued and remains to be performed, paid or discharged, at the date of such termination. However, upon termination no further obligations under this Agreement shall be incurred by the Parties. Moreover, termination of this Agreement shall not release either Party of the obligations of confidentiality set forth in Section 9.01.

[*] Confidential treatment requested; certain information omitted and filed separately with the SEC.

(b) PII Indemnification of RBX.

(c) Indemnification Procedure.

(i) If any action is brought against a party entitled to indemnification under Section 12.01(a) or 12.01(b), as applicable, (each, an “Indemnified Party”), such Indemnified Party or Parties shall promptly notify the party obligated to provide indemnification (an “Indemnifying Party”) in writing of the institution of such action.

(ii) Promptly upon receipt of notice pursuant to subparagraph (a) above, the Indemnifying Party shall promptly assume the defense of such action, including, without limitation, the employment of counsel reasonably satisfactory to such Indemnified Party or Parties, and payment of expenses. An Indemnified Party or Parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties, unless: (A) the employment of such counsel shall have been authorized in writing by the Indemnifying Party in connection with the defense of such action; or (B) the named parties to such action include both the Indemnified Party or Parties and the Indemnifying Party and such Indemnified Party or Parties shall have reasonably concluded that there may be one or more legal defenses available to it or them or to other Indemnified Parties which are different from, or in addition to, those available to the Indemnifying Party. In either of the foregoing events, such fees and expenses shall be borne by

[*] Confidential treatment requested; certain information omitted and filed separately with the SEC.

the Indemnifying Party and the Indemnifying Party shall not have the right to direct the defense of such action on behalf of the Indemnified Party or Parties. Notwithstanding anything to the contrary set forth herein, under no circumstances shall the Indemnifying Party be obligated to assume responsibility for the expenses for more than one counsel for all of the Indemnified Parties as a group.

(iii) Notwithstanding anything contained in this Section 12.01(c) to the contrary, the Indemnifying Party shall not be liable for any settlement of any such Claim or action effected without its written consent, which consent shall not be unreasonably withheld. The Indemnifying Party shall have the right to settle or compromise any action, or permit a default or consent to the entry of judgment in, or otherwise seek to terminate, any pending or threatened action, in respect of which indemnity may be sought hereunder (whether or not any Indemnified Party is a party thereto), provided such settlement, compromise, consent, or termination includes a disclaimer of any fault of the Indemnified Party and an unconditional release of each Indemnified Party from all liability in respect of such action. In the event such an unconditional release is not obtainable for each Indemnified Party, then the Indemnifying Party must obtain the prior written consent of any Indemnified Party not so released before the Indemnifying Party may enter into such settlement, compromise, consent or termination, which consent shall not be unreasonably withheld or delayed.

(d) Limitation on Liability. IN NO EVENT SHALL EITHER PARTY OR ITS AFFILIATES, OR THEIR DIRECTORS, OFFICERS, EMPLOYEES OR AGENTS BE LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES, WHETHER BASED UPON A CLAIM OR ACTION OF CONTRACT, WARRANTY, NEGLIGENCE, STRICT LIABILITY OR OTHER TORT, OR OTHERWISE ARISING OUT OF THIS AGREEMENT; PROVIDED, HOWEVER, THAT THIS LIMITATION WILL NOT LIMIT THE INDEMNIFICATION OBLIGATIONS OF SUCH PARTY UNDER THE PROVISIONS OF THIS ARTICLE XII FOR SUCH DAMAGES CLAIMED BY A THIRD PARTY (EXPRESSLY EXCLUDING ANY SUBLICENSEE, AFFILIATE OR THIRD PARTY PARTNER OF PII).

(e) Payment of Indemnification. Upon the final, nonappealable determination of liability and the amount of the indemnification payment under this Article, the indemnifying Party will pay such amount to the Indemnified Party in immediately available funds within thirty (30) days after such determination.

12.02. Product Recalls and Insurance.

(a) Product Recalls. PII shall oversee and handle, at its own cost and expense, all physical aspects relating to any withdrawal or recall of the Licensed Products sold by PII or its Affiliates, their respective sublicensees or a Third Party Partner in the Territory;

(b) Insurance. During the term of this Agreement and for a period of five (5) years after its expiration or earlier termination, each Party shall obtain, at its sole cost and expense, product liability insurance, or shall set up, at its sole cost and expense, a self insurance arrangement, that meets the following requirements:

(i) the insurance shall insure such Party against all liability related to the Products (whether that Party’s liability arises from its own conduct or by virtue of its participation in this Agreement), including liability for bodily injury, property damage, wrongful death, and any contractual indemnity obligations imposed by this Agreement; and

(ii) the insurance shall be in amounts, respectively, that are reasonable and customary in the United States in the pharmaceutical industry, but in no event shall the product liability insurance maintained by each Party cover less than [*] per occurrence (or claim) and an annual aggregate of [*]. Each Party shall provide written proof of the existence of such insurance to the other Party upon request.

12.03. Arbitration.

(a) Pre-Arbitration Efforts. If a dispute arises between the Parties as to the interpretation or performance of any of the provisions of this Agreement or as to matters related to but not covered by this Agreement, then the Parties shall consult initially to try to resolve the matter amicably. If they shall not be capable of resolving the matter within thirty (30) days of the dispute arising, the matter shall be dealt with in accordance with the provisions of Section 12.03(b).

(b) Arbitration Procedures. All disputes arising out of or in connection with the Agreement shall be settled by final and binding arbitration by the American Arbitration Association (“AAA”), under its commercial rules then in effect except as provided herein. The arbitration will be conducted in New York, NY or such other geographically neutral site within the United States that is mutually agreed by the Parties. All proceedings shall be held in English and a transcribed record prepared in English. The parties shall choose, by mutual agreement, one arbitrator within twenty (20) days of the filing of an arbitration demand with the AAA. If the parties are unable to appoint an arbitrator within the time herein provided or any extension of time that is mutually agreed on, one arbitrator will be appointed by PII, one arbitrator will be appointed by RBX, and the third arbitrator will be appointed by the two arbitrators within thirty (30) days of the date on which the initial period for appointment of a sole arbitrator by mutual agreement lapsed. The award rendered by the arbitrator shall include all costs of arbitration, reasonable attorneys’ fees and reasonable costs for expert and other witnesses, and judgment on such award may be entered in any court having jurisdiction thereof. Nothing in this Agreement shall be deemed as preventing either party from seeking injunctive relief (or any other provisional remedy) from any court having jurisdiction over the Parties and the subject matter of the dispute as necessary to protect either Party’s name, proprietary information, trade secrets, know-how or any other proprietary right. If the issues in dispute involve scientific or technical matters, any arbitrator chosen hereunder shall have educational training and/or experience sufficient to demonstrate a reasonable level of knowledge in the field of biotechnology.

12.06. Severability. Each Party agrees that, should any provision of this Agreement be determined by a court of competent jurisdiction to violate or contravene any applicable law or policy, such provision will be modified by the court to the extent necessary to comply with the applicable law or policy, and such modified provision and the remainder of the provisions hereof will continue in full force and effect; and if such provision cannot be so modified, it shall be severed from this Agreement and the remaining provisions shall be equitably adjusted if necessary, and shall remain in full force and effect.

12.07. Waiver. The waiver of a breach hereunder may be affected only by a writing signed by the waiving Party and shall not constitute a waiver of any other breach. Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, excepting only as to an express written and signed waiver as to a particular matter for a particular time period.
