ARTICLE 2.

GRANT OF LICENSE

2.1. License. EMORY hereby grants LICENSEE an exclusive right and license under the Licensed Patents to make, have made, use, import, offer for Sale, and Sell Licensed Products and to practice Licensed Technology for the Field of Use in the Licensed Territory during the term of this Agreement. If any Affiliate exercises any rights granted by EMORY hereunder, LICENSEE shall remain primarily liable to EMORY for the duties and obligations of any Affiliate hereunder, and any breach hereof by an Affiliate is deemed to be a breach by LICENSEE of this Agreement. Except for the right to grant sublicenses under Article 2.3 (as qualified by Articles 2.4 through 2.9), no other rights or licenses are granted.

2.2. Retained License. EMORY retains on behalf of itself, and any research collaborators, a royalty-free right and license to make and use Licensed Products and to practice Licensed Technology for research and educational purposes only.

2.3. Sublicenses. Provided that written approval of EMORY is obtained in advance, which approval shall not be unreasonably withheld, (provided that if the approval of EMORY is withheld solely on the basis of the fact that the financial obligations of the sublicensee under the sublicense would be materially less favorable to EMORY than those of LICENSEE hereunder,

such withholding of approval shall not be deemed to be unreasonable), LICENSEE shall have the right to grant sublicenses (including further sublicenses thereunder), consistent with this Agreement. If the proposed sublicensee is Triangle Pharmaceuticals, Inc. (“Triangle”) and EMORY has not responded to LICENSEE’s request to sublicense within ten (10) business days after receipt of a proposed sublicense agreement between PHARMASSET and Triangle, such agreement will be assumed to be approved. If the proposed sublicensee is any party other than Triangle and Licensee provides EMORY with a copy of a term sheet promptly following its adoption by Licensee and such sublicensee and EMORY has not responded to LICENSEE’s request to sublicense within fifteen (15) business days after receipt of a proposed sublicense agreement between PHARMASSET and such sublicense, such agreement will be assumed to be approved.

2.4. Sublicensee Performance. EMORY agrees that any sublicensee’s performance of its diligence obligations as set forth in a sublicense agreement approved by EMORY shall be deemed to be performance by LICENSEE of its diligence obligations under this License Agreement including, but not limited to, those set forth in Article 3 hereof. LICENSEE further agrees to attach redacted copies of pertinent portions of this Agreement to sublicense agreements.

2.5. Sublicense Restrictions. The right to sublicense granted to LICENSEE under Article 2.3 is subject to the following conditions:

2.5.1. Within thirty (30) days after LICENSEE enters into any sublicense, LICENSEE must deliver to EMORY a complete copy of the sublicense written in the English language.

2.5.2. In the event of a termination hereof under Article 12.2, all payments then or thereafter due to LICENSEE from each of its sublicensees shall, upon notice from EMORY to any such sublicensee, become owed directly to EMORY for the account of LICENSEE; provided that EMORY shall remit to LICENSEE the amount by which such payments in the aggregate exceed the total amount owed by LICENSEE to EMORY.

2.5.3. Even if LICENSEE enters into sublicenses, LICENSEE shall remain primarily liable to EMORY for all of LICENSEE’s duties and obligations contained in this Agreement, and in the event of any act or omission of a sublicensee that would be a breach of its sublicense, LICENSEE shall be liable for the performance of its duties and obligations under this Agreement in respect of those matters as to which such breach by sublicensee has occurred.

2.6. Form of Sublicensee Payments. Except as provided for in Article 2.8, LICENSEE shall not receive from sublicensees anything of value in lieu of cash payments in consideration for any sublicense under this Agreement without the prior written permission of EMORY.

2.7. Delivery of Sublicense Agreements. LICENSEE agrees to forward to EMORY a copy of any and all sublicense agreements promptly upon execution by the parties.

2.8. Sharing of Sublicensee Payments. LICENSEE and EMORY agree to share cash actually received from sublicensing Licensed Patents and Licensed Technology in the following manner:


	EMORY		LICENSEE
Running royalties received from sublicensee(s)	[***]	%	[***]	%

Cash or the cash value of other valuable consideration received from sublicense issue fees, milestone payments, or other fees other than royalties (excluding only (i) funds actually received for use by LICENSEE solely for the pre-clinical or clinical development of Enantionmerically Enriched FTC and (ii) additional equity investments in LICENSEE up to $8 million).	[***]	%	[***]	%

2.9. Taxes. LICENSEE further agrees that all sublicenses shall contain an agreement substantially similar to Article 5.2 of this Agreement. If a sublicensee shall fail to comply with such provision (or the sublicense does not provide for such provision), then EMORY’s percentage, as determined in Article 2.8, shall be adjusted so that EMORY shall receive an amount equal to [***] Percent ([***]%) of the royalty, as calculated without reduction for Taxes withheld or due to be withheld on the payment.

2.10. Sublicense Royalty Floor. LICENSEE agrees that payments to EMORY in respect of royalties received by LICENSEE from any sublicensees shall not be less than [***] ([***]%) percent of the Net Selling Price of all Licensed Products Sold by the sublicensee.

2.11. Milestone Payment. LICENSEE shall pay EMORY, as additional partial consideration a Marketing Milestone of [***] ($[***]) Dollars. The Marketing Milestone shall be payable as follows: on each [***] ($[***]) Dollars in Net Sales (up to a cumulative total of [***] ($[***]) Dollars in Net Sales within the Licensed Territory, a Marketing Milestone

Payment of [***] ($[***]) Dollars will be due (up to an aggregate of [***] ($[***]) Dollars). Upon payment of the final [***] ($[***]) Dollars in respect of the first [***] ($[***]) Dollars in cumulative Net Sales within the Licensed Territory, the Marketing Milestone Payment obligation shall terminate. Each Marketing Milestone Payment shall be due at the same time the royalty report coveting the royalty period in which such incremental [***] ($[***]) Dollars in Net Sales has been achieved, is due.

2.12. No Implied License. The license and right granted in this Agreement shall not be construed to confer any rights upon LICENSEE by implication, estoppel, or otherwise as to any technology not specifically identified in this Agreement as Licensed Patents or Licensed Technology.

2.13. Government Rights. The Licensed Patents, Licensed Technology, or portions thereof were developed with financial or other assistance through grants or contracts funded by the United States government. LICENSEE acknowledges that in accordance with Public Law 96-517 and other statutes, regulations, and Executive Orders as now exist or may be amended or enacted and the U.S. Government Licenses, the United States government has certain rights in the Licensed Patents and Licensed Technology. LICENSEE shall take all action necessary to enable EMORY to satisfy its obligations under any federal law relating to the Licensed Patents or Licensed Technology. If the United States government should take action which renders it impossible or impractical for EMORY to grant the rights and license granted herein to LICENSEE under this Agreement or otherwise perform EMORY’s obligations under this Agreement, EMORY or LICENSEE may terminate this Agreement immediately by notice to the other party. LICENSEE shall not have any right to the return of any payments of any kind made by it to EMORY prior to the date of termination.

2.14. Cooperation. During the term of this License Agreement, EMORY shall, at its expense, fully cooperate with LICENSEE in dealing with any persons or entities who may have been previously granted any rights, including manufacturing rights, in respect of any Licensed Patents, Licensed Products or Licensed Technology (all as defined in this License Agreement) including visits to the facilities of any such persons and entities if deemed advisable by EMORY. Without limiting the foregoing, in the event that Triangle is a sublicensee hereunder, EMORY shall use reasonable efforts to facilitate the collaboration between LICENSEE and Triangle, and regardless of the identity of sublicensees EMORY shall make available to LICENSEE any data or intellectual property or other rights relating to FTC obtained during the term hereof from GlaxoWellcome to the extent that making such items available does not violate any obligation of EMORY to GlaxoWellcome or other third party.

2.15. Access to Materials. During the term of this License Agreement, EMORY shall provide LICENSEE with full access upon reasonable notice to all documents and samples, including reagents, which may be in the possession or control of EMORY relating to both the Licensed Patents and Licensed Technology provided to LICENSEE hereunder and shall, within a reasonable period, provide LICENSEE with a true and complete list thereof.

2.16. Cooperation in Regulatory Activities. During the term of this License Agreement, EMORY shall cooperate fully with LICENSEE, in respect of LICENSEE’s pursuit of all regulatory approvals to market and sell Enantiomerically Enriched FTC, provided that all such activities shall be undertaken at the sole expense of LICENSEE.

2.17. U.S. Manufacture. LICENSEE, either directly or through Affiliates or sublicensees, agrees to use its best efforts to manufacture Licensed Products for United States Sales substantially in the United States.

ARTICLE 3.

DILIGENCE AND COMMERCIALIZATION

3.1. Diligence and Commercialization. LICENSEE shall use its reasonable best efforts, either directly or through Affiliates or sublicensees, throughout the term of this Agreement to comply with LICENSEE’s Development Plan and to bring Licensed Products to market in accordance with LICENSEE’s Development Plan through a thorough, vigorous, and diligent program for exploitation of the right and license granted in this Agreement to LICENSEE and to create, supply, and service in the Licensed Territory as extensive a market as possible. In no instance shall LICENSEE’s reasonable best efforts be less than efforts customary in LICENSEE’s industry.

3.2. Lack of Diligence. If EMORY concludes that LICENSEE is not diligent in development or Sales of Licensed Products pursuant to Article 3.1 for any reason other than a) the withholding by a regulatory agency of marketing approval despite LICENSEE’s diligent effort to obtain such approval; or b) unanticipated technical or scientific problems which have been promptly reported to EMORY in writing; or (c) other causes beyond the reasonable control of LICENSEE which have been promptly reported to EMORY in writing; then EMORY may give notice to LICENSEE stating the basis for its conclusion and, upon the request of EMORY, LICENSEE shall show cause why the license granted hereunder should not be terminated. If within ninety (90) days after LICENSEE’s receipt of said notice, the parties have not resolved the matter through good faith negotiations in a mutually acceptable manner, the parties shall submit the dispute to arbitration under the provisions of Article 14 of this Agreement.

ARTICLE 4.

CONSIDERATION FOR LICENSE

4.1. Purchased Shares. In partial consideration for the license granted to LICENSEE under this Agreement, LICENSEE shall issue to EMORY such number of shares (the “Purchased Shares”) of LICENSEE’s Common Stock, no par value Common Stock, as will cause EMORY to own shares of Common Stock representing [***] percent ([***]%) (in addition to any percentage owned at the date hereof by virtue of any other extant license agreement between EMORY and LICENSEE) of the outstanding shares of the capital stock of LICENSEE on a fully diluted basis, assuming the exercise, conversion and/or exchange of all outstanding securities of LICENSEE for or into shares of Common Stock, all on the terms and conditions as set forth in the stock purchase agreement between LICENSEE and EMORY (“Stock Purchase Agreement”), a copy of which is attached as EXHIBIT “E”.

4.2. Antidilution. In partial consideration for the license granted to LICENSEE under this Agreement, until LICENSEE’s receipt of [***] ($[***]) cash in equity financing prior to (and excluding) the initial underwritten public offering for cash of LICENSEE’s equity securities, LICENSEE shall issue to EMORY, for no additional consideration, from time to time, such number of additional shares of Common Stock (collectively, the “Additional Purchased Shares”) as will cause EMORY to continue to hold shares of Common Stock representing such additional [***] percent ([***]%) of the outstanding capital stock of LICENSEE (referenced in Section 4.1 hereof) on a fully diluted basis, assuming the exercise, conversion and/or exchange of all outstanding securities of LICENSEE for or into shares of Common Stock.

4.3. Royalties. As partial consideration for the license granted to LICENSEE under this Agreement, LICENSEE or Affiliates which are not also sublicensees shall pay EMORY a

royalty equal to [***] percent ([***]%) of the Net Selling Price of all Licensed Products Sold by LICENSEE or such Affiliates during the term of this Agreement. Royalties shall be due and payable on a semi-annual basis on December 31 and June 30 of each year.

4.4. Minimum Royalties. LICENSEE shall pay annual minimum royalties to EMORY in accordance with the following schedule:

Year after NDA Registration in the First Major Market


2	$	[***]
3	$	[***]
4	$	[***]
5	$	[***]
6 and thereafter	$	[***]

If the actual royalties due under Article 4.3 in any year are greater than the minimum royalty payment due for that year, the minimum royalty will be credited against actual royalties due in that year.

If the minimum royalties due in any year are greater than the actual royalties due for that year, the difference shall become a future credit against [***] percent ([***]%) of each earned royalty payment which LICENSEE would be required to pay pursuant to Article 4.3 hereof until the entire credit is exhausted. In no event shall LICENSEE make a payment less than the minimum royalty due in that year.

Minimum royalties shall be paid for a period of [***] ([***]) years after NDA registration in the first Major Market. After such [***] ([***]) year period, minimum royalties shall be paid only so long as the manufacture, use, offer for Sale, Sale or importation of Licensed Products in the Licensed Territory would, in the absence of this license, infringe a Valid Claim.

4.5. Reimbursement for Patent Expenses. LICENSEE shall reimburse EMORY for all reasonable external out-of-pocket fees, costs, and expenses heretofore and hereafter during the term of this Agreement paid or incurred by EMORY in filing, prosecuting, and maintaining the Licensed Patents in the Licensed Territory (excluding any currently pending legal proceedings), which expenses are not required to be reimbursed by Triangle or any prior licensee. LICENSEE shall deliver such reimbursement to EMORY within ninety (90) days after EMORY notifies LICENSEE of out-of-pocket fees, costs and expenses and provides LICENSEE with documentation, including copies of invoices, from time to time of the amount of such fees, costs, and expenses which have been paid or incurred by EMORY.

ARTICLE 5.

REPORTS AND PAYMENTS

5.1. Payments. Unless otherwise specified, all payments required under this Agreement shall be payable within thirty (30) days of the due date for each payment. All payments due under this Agreement shall be made in person or via the United States mail or private courier to the following address:

5.2. Tax Matters. All payments made to EMORY under the terms of this Agreement (without limitation including the delivery of the Purchased Stock and the Additional Purchased Stock, the royalties, the minimum royalties and the amounts due under Article 2.8 and 2.11) shall be made free and clear of any tax, withholding or other governmental charge or levy (other than taxes imposed on the net income of EMORY), all such non-excluded amounts being taxes.

Should the LICENSEE be obligated by law to withhold any Taxes, the payment due hereunder shall be increased such that after the withholding of the appropriate amount EMORY receives the amount that would have been paid but for the Taxes withheld. Should EMORY be obligated to pay such Taxes, and such Taxes were not satisfied by way of withholding, LICENSEE shall promptly reimburse EMORY for such payment, in an amount such that after the payment of the Taxes, EMORY has received the same amount that it would have received had such Taxes not been payable.

5.3. Progress Reports. LICENSEE will provide EMORY with semi-annual progress reports detailing the activities of LICENSEE relevant to LICENSEE’s Development Plan.

5.4. Royalty Reports.

(f) in case no payment is due, LICENSEE shall so report.

Each royalty report shall be accompanied by the payment of all royalties due for the six months in question. Any minimum royalty payment due under Article 4.4 shall accompany the report for six months ending on December 31 of the applicable License Agreement Year.

5.5. Currency Conversion.

5.6. Interest. Payments required under this Agreement shall, if overdue, bear interest until payment at a per annum rate [***] percent ([***]%) above the prime rate in effect as published in the Wall Street Journal on the due date. The payment of such interest shall not foreclose EMORY from exercising any other rights it may have because any payment is late.

ARTICLE 6.

RECORDS

6.1. Records of Sales. During the term of this Agreement and for a period of three (3) years thereafter, LICENSEE shall keep at its principal place of business true and accurate records of all Sales in accordance with generally accepted accounting principles in the respective country where such Sales occur and in such form and manner so that all royalties and other payments owed to EMORY may be readily and accurately determined.

6.2. Audit of Records. EMORY shall have the right, from time to time at reasonable times during normal business hours through an independent certified public accountant, to examine the records of LICENSEE in order to verify the calculation of any royalties payable under this Agreement. Such examination and verification shall not occur more than once each License Agreement Year and the calendar year immediately following termination of this Agreement. Unless otherwise agreed in writing by LICENSEE, the fees and expenses of performing such examination and verification shall be borne by EMORY. LICENSEE shall, subject to Article 14 hereof, immediately pay EMORY any underpayment identified by such independent certified public account. In addition, if such examination reveals an underpayment by LICENSEE of more than five percent (5%) for any six-month period examined, LICENSEE shall reimburse EMORY for all expenses of the accountant reasonably incurred in performing the examination.

ARTICLE 7.

PATENT PROSECUTION

7.1. Triangle License Agreement. LICENSEE acknowledges that the Licensed Patents are subject to an extant License Agreement made and entered into between EMORY and Triangle on April 17, 1996 (hereinafter the “Triangle License”), a redacted copy of which is attached hereto as EXHIBIT “F”. Under the Triangle License, EMORY agreed to prosecute, acquire from the relevant patent offices, defend and maintain and handle any litigation, interference, opposition or other action pertaining to the validity, enforceability, allowability or subsistence (all of the foregoing activities being referred to as “Patent Prosecution Activities”) of all such Licensed Patents in the following countries: United States, EPO countries, Japan, Canada and Australia. EMORY further agreed that if EMORY decided to abandon or allow to

lapse any patent application or patent within the Licensed Patents or discontinue any other Patent Prosecution Activities in respect thereof in any country of the licensed territory thereunder, EMORY would inform Triangle and Triangle would be given the opportunity to assume such Patent Prosecution Activities. The Triangle License provides that Triangle shall reimburse EMORY for all such Patent Prosecution Activities. The Triangle License further provides mechanisms for Triangle to voluntarily discontinue its obligations to reimburse EMORY for such Patent Prosecution Activities, in which case EMORY may discontinue such activities, as well as mechanisms for the loss of Triangle’s license rights with respect to patent applications or issued patents for which Triangle fails to reimburse EMORY for Patent Prosecution Activities.

7.2. Management of Licensed Patents Subject to the Triangle License. To the extent not prohibited by the Triangle License, EMORY shall keep LICENSEE informed regarding significant developments and activities with respect to Licensed Patents which are subject to the Triangle License. LICENSEE shall, subject to the Triangle License, be afforded reasonable opportunities to advise EMORY and cooperate with EMORY in such Patent Prosecution Activities pertaining to the Licensed Patents. In the event that EMORY abandons or allows to lapse any Licensed Patent which is subject to the Triangle License or discontinues any other Patent Prosecution Activities in respect thereof in any country of the licensed territory thereunder, and Triangle does not assume such Patent Prosecution Activities (or in the event that Triangle discontinues reimbursement to EMORY for EMORY’s Patent Prosecution Activities), EMORY shall promptly so notify LICENSEE in writing in which case LICENSEE shall have the right, with patent attorneys selected by it, to perform such Patent Prosecution Activities or to reimburse EMORY therefor, as the case may be. In all cases, each party hereto shall give due consideration to the other party’s or its sublicensees’ position with request to Patent Prosecution

Activities and provide the other party with copies of all domestic and foreign patent office correspondence with respect to such Licensed Patents as well as such additional documentation as a party hereto may reasonably request relating to such Licensed Patents.

7.3. Licensed Patents Not Subject to the Triangle License. If, during the term of this Agreement, LICENSEE wishes EMORY to undertake any Patent Prosecution Activities as that term is defined in Section 7.1, with respect to any Licensed Patent which, at such time, is not, for any reason, subject to the Triangle License, EMORY shall cooperate with LICENSEE in establishing appropriate procedures and mechanisms to undertake such activities. Unless otherwise agreed in writing, all such activities shall be primarily managed by EMORY (and EMORY shall inform and consult with LICENSEE with respect thereto). LICENSEE shall be responsible for promptly reimbursing EMORY for all its reasonable out-of-pocket costs incurred in pursuing such Patent Prosecution Activities.

7.4. Right of First Refusal. LICENSEE acknowledges that it is bound by the right of first refusal provisions of Section 2.7 of the Triangle License, a copy of which is in LICENSEE’s possession.

7.5. Extension of Licensed Patents. LICENSEE may request that EMORY have the normal term of any Licensed Patent extended or restored under a country’s procedure of extending life for time lost in government regulatory approval processes, and the expense of same shall be borne in accordance with the terms of Article 4.5. LICENSEE shall assist EMORY to take whatever action is necessary to obtain such extension. In the case of such extension, royalties pursuant to Article 4 hereof shall be payable until the end of the extended life of the patent. In the event that LICENSEE does not elect to extend Licensed Patent(s), EMORY may, at its own expense, effect the extension of such Licensed Patent(s) and if in such

case EMORY elects to pay such expenses, such extended Licensed Patents shall not be subject to any license granted to LICENSEE hereunder.

7.6. Patent Prosecution Activities by Sublicensee. In the event that any sublicense hereunder provides that any Patent Prosecution Activities which LICENSEE is authorized to perform may be performed by such sublicensee, EMORY shall communicate directly with such sublicensee with respect thereto.

ARTICLE 8.

ABATEMENT OF INFRINGEMENT

8.1. Abatement. LICENSEE shall promptly inform EMORY and EMORY will promptly notify LICENSEE of any suspected infringement of any Licensed Patents. LICENSEE acknowledges that pursuant to the extant Triangle License, Triangle has been granted the first opportunity to pursue infringement activities with respect to all Licensed Patents falling within the scope of the Triangle License. During the term of this Agreement, but subject to any prior rights granted to Triangle, EMORY and LICENSEE shall have the right to institute an action for infringement of the Licensed Patents against such third party in accordance with the following:

(a) If EMORY and LICENSEE agree to institute suit jointly, the suit shall be brought in both their names and the out-of-pocket costs thereof shall be borne by LICENSEE and any recovery shall first be used to reimburse all out-of-pocket costs. Any recovery or settlement received by EMORY and/or LICENSEE for punitive or exemplary damages shall be shared equally, and any other recovery or settlement received, including compensatory damages or damages based on a loss of revenues, shall be paid to LICENSEE, and LICENSEE shall pay to EMORY an amount representing the royalty which would have been paid by LICENSEE on such amount in accordance with the provisions of Article 4 had such amount been accrued by LICENSEE as Sales. LICENSEE and EMORY shall agree in good

faith upon the manner in which they shall exercise control over such action. EMORY may, if it so desires, also be represented by separate counsel of its own selection, the fees for which counsel shall be paid by EMORY and first reimbursed from any recovery after reimbursement to LICENSEE as provided above in the event of joint suit;

(b) In the absence of agreement to institute a suit jointly, EMORY may institute suit, and, at its option, name LICENSEE as a plaintiff. EMORY shall bear the entire cost of such litigation and shall be entitled to retain the entire amount of any recovery or settlement; and

(c) In the absence of agreement to institute a suit jointly and if EMORY notifies LICENSEE that it has decided not to join in or institute a suit, as provided in (a) or (b) above, LICENSEE may institute suit and, at its option, name EMORY as a plaintiff. LICENSEE shall bear the entire cost of such litigation, including defending any counterclaims brought against EMORY and paying any judgements rendered against EMORY, and shall be entitled to retain the entire amount of any recovery or settlement.

8.2. Abandonment. Should either EMORY or LICENSEE commence a suit under the provisions of this Article and thereafter elect to abandon such suit, the abandoning party shall give timely notice to the other party who may, if it so desires, continue prosecution of such suit, provided that the sharing of expenses and any recovery in such suit shall be as agreed upon in good faith between EMORY and LICENSEE.

ARTICLE 9.

(b) a party may disclose and use the other party’s information where the disclosure and use of such will be necessary to the procurement of patent protection, pursuant to this Agreement, for a Licensed Product;

(c) a party may disclose and use the other party’s information to the extent that it is necessary to aid in the development and commercialization, pursuant to this Agreement, of any Licensed Product provided that any such disclosure of the disclosing party’s information shall be in confidence and subject to provisions the same, or substantially the same, as those in Paragraph 9.1 hereof;

(d) a party may disclose the other party’s information where such disclosure is required by applicable law.

9.3. Prior Agreements. The provisions of this Agreement supersede and shall be substituted for any terms of any prior confidentiality agreement between LICENSEE and EMORY which are not consistent with this Agreement.

ARTICLE 10.

LIMITED WARRANTY, MERCHANTABILITY AND EXCLUSION OF WARRANTIES

EMORY represents and warrants that it has the right and authority to enter into this Agreement and that neither the execution of this Agreement nor the performance of its obligations hereunder will constitute a breach of the terms and provisions of any other agreement to which EMORY is a party.

Upon the expiration of such period, this Agreement shall automatically terminate unless the LICENSEE has cured the breach. Such notice and termination shall not prejudice EMORY’s right to receive royalties or other sums due hereunder and shall not prejudice any cause of action or claim of EMORY accrued or to accrue on account of any breach or default by LICENSEE.

12.5. Failure to Enforce. The failure of EMORY at any time, or for any period of time, to enforce any of the provisions of this Agreement shall not be construed as a waiver of such provisions or as a waiver of the right of EMORY thereafter to enforce each and every such provision.

12.6. Termination by LICENSEE. LICENSEE may terminate this Agreement at its sole discretion upon three (3) months’ written notice to EMORY. In the event of such termination, LICENSEE agrees, upon the request of EMORY, to provide EMORY with all existing data in LICENSEE’s possession or control in support of registration of Licensed Products for the Field of Use with the relevant governmental agencies.

15.9. Severability. All rights and restrictions contained herein may be exercised and shall be applicable and binding only to the extent that they do not violate any applicable laws and are intended to be limited to the extent necessary so that they will not render this Agreement illegal, invalid or unenforceable.

Gentlemen:

The License Agreement by and between Emory University (“Emory”) and Triangle Pharmaceuticals, Inc. (“Triangle”) dated April 17, 1996 (“License Agreement”) under which Emory Granted to Triangle exclusive license rights to commercially develop the (-) enantiomer of FTC provides to Triangle, in Section 2.7 (b) thereof, a right of first refusal with respect to any license or assignment agreement with a third party relating to Emory’s rights to Enantiomerically Enriched FTC (as therein defined) and further provides, in Section 2.7(c) thereof, that a license or assignment to any Permitted Transferee (as therein defined) would be outside the scope of such right of first refusal so long as the Permitted Transferee agrees in writing to be bound by the terms of the right of first refusal prior to entering such license or assignment.

BACKGROUND

A. Concurrently with the execution of this Agreement, University is entering into a License Agreement with Licensee dated the date hereof in respect of enantiomerically enriched FTC (the “License Agreement”), whereby University is licensing to Licensee certain technology owned by University; and

B. In partial consideration for the execution and delivery of the License Agreement by University, Licensee has agreed to issue to University certain shares of Licensee’s capital stock in accordance with the terms and conditions of this Agreement;

NOW, THEREFORE, in consideration of the premises and mutual promises and covenants contained herein, and intending to be legally bound hereby, the parties hereby agree as follows:

PURCHASE OF SHARES

1.1 Purchase. In partial consideration for the execution and delivery of the License Agreement by University, Licensee hereby agrees to sell and issue to University such number of shares (the “Purchased Shares”) of Licensee’s common stock (“Common Stock”), as will cause University to own shares of Common Stock representing [***] percent ([***]%) (in addition to any percentage owned at the date hereof by virtue of any other extant license agreement between Licensee and University) of the outstanding and the reserved shares of the capital stock of Licensee on a fully diluted basis, assuming the exercise, conversion and/or exchange of all outstanding securities of Licensee for or into shares of Common Stock, on the terms and conditions as hereinafter set forth.

1.2 Closing. The purchase and sale of the Purchased Shares shall occur contemporaneously with the execution and delivery of the License Agreement at a closing (the “Closing”) to be held at a time (the “Closing Date”) and place agreed upon by the parties.

Each purchase and sale of any Additional Purchased Shares shall occur at a time and place designated by Licensee, at which University shall deliver to Licensee such documents as Licensee may reasonably require and Licensee shall deliver to University a stock certificate or certificates representing such Additional Purchased Shares.

Articles of Incorporation of Licensee

Amendments to Articles of Incorporation

At a special meeting of the stockholders of the Licensee called for the purpose of amending the Articles of Incorporation of the Licensee, the Articles of Incorporation of the Licensee shall be amended to (i) provide that no restrictions on shares of Common Stock shall exist under the Articles of Incorporation, including without limitation under Sections 3 and 6(d) thereof, other than those arising under securities laws or by contract and (ii) authorize the issuance of shares of Preferred Stock with rights and preferences identical in all respects to shares of Common Stock, except that such shares of Preferred Stock shall have a liquidation preference equal to the consideration per share paid to the Licensee for such shares of Preferred Stock over the rights of the shares of Common Stock and such shares of Preferred Stock shall be convertible at any time and at the election of the holder or holders thereof into shares of Common Stock on a share-for-share basis (subject to customary adjustments to the conversion rate in the event of a stock split, stock dividend or reverse stock split for the shares of Common Stock). University agrees to vote its shares of Common Stock in favor of such amendments to the Articles of Incorporation.

E-13

EXHIBIT C

Valuation Procedure

Whenever the value of the Shares must be determined pursuant to Section 4.2 hereof, within ten (10) days after notice is given by University, University and Licensee shall attempt to agree upon the selection of a disinterested independent qualified investment banking firm or other disinterested independent qualified appraiser (the “Appraiser”) to determine the fair market value of such Shares. If the parties are able to agree upon an Appraiser, then such Appraiser will be instructed to furnish a written valuation or appraisal (an “Appraisal”) within thirty (30) days after its selection. If the parties are unable to agree upon the selection of an Appraiser within a ten (10) day period, then University and Licensee will, within five (5) days after the end of such ten (10) day period, each select an Appraiser to determine the fair market value of such Shares. If either University or Licensee fails to so select an Appraiser, the Appraisal of the Appraiser selected by the other shall determine the fair market value of such Shares. If the higher of the two Appraisals is not more than one hundred ten percent (110%) of the lower Appraisal, then the fair market value of such Shares will be the arithmetic average of the two Appraisals. If the higher of the two Appraisals is equal to or greater than one hundred ten percent (110%) of the lower Appraisal, then the two Appraisers shall, within ten (10) days after the issuance of their respective reports, select a third Appraiser to determine the fair market value of such Shares. The third Appraiser will be instructed to issue a written Appraisal within thirty (30) days after this selection. The third Appraisal shall be arithmetically averaged with the two Appraisals, and the Appraisal furthest from the average of all three Appraisals will be disregarded. The arithmetic average of the two remaining Appraisals will be the fair market value of such Shares.

Each Appraiser engaged to provide an Appraisal pursuant hereto will be instructed (i) to include therein a statement of the criteria applied and assumptions made to determine the fair market value of the Shares, (ii) to arrive at a single calculation of such fair market value rather than alternative calculations or a range of calculations, and (iii) not to attribute a premium or discount based on the fact that the Shares being valued constitutes a majority or less than a majority of the total issued and outstanding Shares of Licensee. Any Appraisal by an Appraiser that fails to follow the instructions set forth in this Exhibit C shall not constitute an Appraisal for purposes of this Agreement; except that the failure of an Appraiser to complete an Appraisal within thirty (30) days as instructed shall not affect the validity of such Appraiser’s Appraisal.

The cost of Appraisal or Appraisals under the first redemption of stock by the University shall be paid as follows: Licensee shall pay for the cost of the first Appraiser. If a second Appraiser is required, University shall pay the cost of the second Appraiser. If a third Appraiser is required, Licensee and University shall share equally the cost of the third Appraiser. With respect to any subsequent redemption of stock in which any Appraiser is engaged, University shall bear the complete cost of such Appraiser or Appraisers.

In lieu of determining the Redemption Price for the Shares by Appraisal, Licensee and University may negotiate and stipulate a Redemption Price on terms mutually acceptable to such parties.

Until the end of such [REDACTED BY EMORY] calendar year, the amount of such credits shall not exceed in any year [REDACTED BY EMORY] of the royalty payments due hereunder in such year. Commencing upon the [REDACTED BY EMORY] calendar year following the year in which such FDA Registration is granted, such credits shall not exceed in any year [REDACTED BY EMORY] of the Annual Minimum payments due in such year.

LICENSOR acknowledges that it shall not be entitled to share in any payment made by a [REDACTED BY EMORY] regardless of how such payment is denominated, that represents reimbursement or advance payment of costs incurred by COMPANY for research, development or other purposes (as agreed by LICENSOR and COMPANY) in COMPANY’s pursuit of regulatory or marketing approval for any Licensed Product. With respect to a [REDACTED BY EMORY] or [REDACTED BY EMORY] concluded prior to Registration in [REDACTED BY EMORY] of the first Licensed Product, the Applicable Percentage shall be [REDACTED BY EMORY]. With respect to a sublicense or other contractual arrangement concluded after Registration in [REDACTED BY EMORY] of the first Licensed Product, the Applicable Percentage shall be [REDACTED BY EMORY].

3.9 THIRD PARTY ROYALTIES.

(a) If COMPANY, its Affiliates or sublicensees determine after consultation with LICENSOR, but at COMPANY’s discretion, that it or they are required to pay royalties or other fees to any third party (including under any third party or GW license to which Section 2.6 applies) because the manufacture, use, offer for sale, importation, or sale of a Licensed Product infringes any patent or other intellectual property rights of such third party in a given country (“Third Party Royalties”), COMPANY, its Affiliates or sublicensees may deduct from running royalties thereafter due to LICENSOR (per Section 3.4 of this Agreement) with respect to the Net Selling Price of such Licensed Product in such country up to [REDACTED BY EMORY] of the Third Party Royalties. In no event shall the royalties due on such Sales of such Licensed Product in such country on account of any reduction pursuant to this Subsection 3.9(a) be thereby reduced to less than [REDACTED BY EMORY] on such Sales of such Licensed Product in such country.

(b) If the sum of the royalties paid hereunder and Third Party Royalties for a given Licensed Product in a given country exceeds, at any time, [REDACTED BY EMORY] of the Net Selling Price for such Licensed Product, upon COMPANY’s request, LICENSOR and COMPANY agree to negotiate in good faith in an effort to agree on a reduction in the royalties payable hereunder to LICENSOR for such Licensed Product in such country.

Should a compulsory license be granted to any third party in any country of the Licensed Territory to make, have made, use, import, offer for sale or sell Licensed Products, the royalty rate payable thereunder for sales of the Licensed Products by COMPANY in such country shall be adjusted to match any lower royalty rate granted to the third party for such country. COMPANY shall provide LICENSOR with prompt written notice of any governmental or judicial procedures initiated in any country to impose a compulsory license.

COMPANY shall take all reasonable and legal steps as COMPANY deems appropriate which are available to oppose such compulsory license and shall, at LICENSOR’s request, cooperate reasonably with LICENSOR in any legal action which LICENSOR may wish to take to oppose such compulsory license, which action shall be at LICENSOR’s sole expense and may not be taken by LICENSOR if such action would materially jeopardize the validity of any Licensed Patents in such country.

3.11 REDUCTION IN ROYALTY DUE TO INVALID CLAIMS. In the event that all applicable claims of all patents or patent applications included within the Licensed Patents under which COMPANY is selling or actively developing a Licensed Product shall be held invalid or not infringed by the Licensed Products COMPANY is selling or actively developing by a court of competent jurisdiction in a given country of the Licensed Territory, whether or not there is a conflicting decision by another court of competent jurisdiction in such country, COMPANY may cease all royalty payments on its, its Affiliates’ or its sublicensees’ sales of such Licensed Product


* Confidential Treatment Requested		14

covered by such claims and, if it does so, shall deposit such royalty payments in an interest-bearing escrow account until such judgment is finally reversed by an unappealed or unappealable decree of a court of competent jurisdiction of higher dignity in such country or is otherwise unappealable or is unappealed within the time allowed therefor; provided, however, that if such judgment is finally reversed by an unappealed or unappealable decree of a court of competent jurisdiction of higher dignity in such country, the former royalty payments shall be resumed and the royalty payments not theretofore made and interest earned thereon shall become due and payable to LICENSOR.

3.12 MOST FAVORED LICENSEE. Should COMPANY’s exclusive license hereunder become nonexclusive in any country of the Licensed Territory due to LICENSOR’s exercise of their conversion remedy and should LICENSOR thereafter grant to a third party a license for any Licensed Product in such country containing more favorable terms than those granted to COMPANY, then in such an event, LICENSOR promptly shall notify COMPANY and or its Affiliates or sublicensees, as applicable, and COMPANY and such Affiliates or sublicensees shall have the benefit of such more favorable terms provided they accept any less favorable terms contained in such license.

(i) fulfill all of its obligations under the Yale Agreement, including, but not limited to, any royalty obligations set forth therein;

unapprovable by the FDA (which notice is hereinafter referred to as a “Failure of Diligence Notice”).

Upon receipt of such a Failure of Diligence Notice, COMPANY shall be deemed to have failed to meet its diligence obligations, and LICENSOR may thereafter invoke any remedy provided for in this Article without any further notice to COMPANY.

(b) In the event COMPANY fails to meet any diligence requirement set forth herein in respect of a Licensed Product for a given [REDACTED BY EMORY], LICENSOR shall have the option in its sole discretion to (i) terminate the Agreement within the entire Licensed Territory or any portion of the Licensed Territory for such [REDACTED BY EMORY], (ii) convert the license granted in this Agreement into a non-exclusive license within the entire Licensed Territory or any portion of the Licensed Territory for such Major Indication, or (iii) terminate the Agreement within a portion of the Licensed Territory and convert the license granted in this Agreement into a non-exclusive license within a portion of the Licensed Territory for such [REDACTED BY EMORY].

Upon expiration of such [REDACTED BY EMORY] period, LICENSOR 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 obligation is met during such [REDACTED BY EMORY] period.

6.3 PROGRESS REPORTS. COMPANY shall, no less frequently than once every [REDACTED BY EMORY] until a Licensed Product has been Registered, provide LICENSOR with a written report detailing all activities of COMPANY, its Affiliates and sublicensees related

prior notice to COMPANY, such patent application or issued patent shall not be considered a Licensed Patent and LICENSOR shall be free, at its election, to abandon or maintain the prosecution of such patent application or issued patent or grant rights to such patent application or issued patent to third parties.

(c) COMPANY reserves the right to terminate its obligations pursuant to Section 7.1 with respect to any patent application or patent included in the Licensed Patents in any country or countries upon at least thirty (30) days’ prior written notice to LICENSOR.

7.2 LICENSED PATENTS JOINTLY ASSIGNED TO COMPANY AND LICENSOR. Any invention relating to a Licensed Compound, the invention of which under applicable patent law is attributed jointly to at least one employee of LICENSOR and at least one employee of COMPANY, shall be assigned by such employees to such LICENSOR and COMPANY.

Thereafter, LICENSOR’s rights to such patent application and issued patent shall no longer be included in the license granted pursuant to Section 2.1 and COMPANY shall further, upon LICENSOR’s request, license COMPANY’s rights under such jointly assigned patents to LICENSOR or any licensees of LICENSOR, non-exclusively on a royalty free basis.
