SG hereby grants GNE the right to elect to include SGN 11 and 12 specifically (other than single chain portions thereof as set forth in Section 1.3, which are included in the grant of rights under Section 5.1) as Antibodies, and the patents related thereto as SG Patents and BMS Patents, as applicable, for use in the BMS Field under this Agreement as follows (the "SGN 11/12 Option"): for a period of [*] ([*]) years from the Effective Date, GNE shall have the right to exercise the SGN 11/12 Option; provided, however, that if no [*] for SGN 11&12 agreed to by both GNE and SG shall have been successfully completed (i.e., it has proved its primary hypothesis) within such [*] ([*]) year period, then the period to exercise the SGN 11/12 Option under this Agreement shall be extended until 90 days following GNE's receipt of a final report of the results of such a [*]. If GNE elects to exercise the SGN 11/12 Option, GNE shall notify SG of such election in writing, and within thirty (30) days of such notice shall make a payment to SG in the amount of [*] dollars ($[*]). From and after the receipt by SG of the payment set forth above, both SGN 11&12 will be considered Antibodies under this Agreement, and all SG Patents and BMS Patents related to SGN 11 and SGN 12 shall be added to this Agreement, and royalties and milestones applicable to its development and commercialization shall be determined in accordance with Section 6.1. If a Licensed Product incorporating SGN 11 and SGN 12 is the first product to complete a milestone set forth in Section 6.1(a), then the applicable amount set forth in Section 6.1(a) will become due and payable to SG.

5.6 [*]; [*]

(a) Subject to the other terms of this Agreement, SG hereby grants GNE a [*] during the Term of this Agreement to obtain an [*] license to develop and commercialize [*] for use in the BMS Field in the Territory. During the Term of this Agreement, if SG receives a [*] a third party to begin [*] to reach a definitive development, licensing or marketing agreement that would grant a third party a license in any proposed territory to intellectual property owned or licensed by SG necessary or useful to develop, market, promote, use, import, export, offer for sale and/or sell [*], then SG [*] of SG's interest in negotiating and [*] for [*] in the Territory and of the material business terms on which SG is [*] such technology, including sufficient information regarding the scope of the SG technology which would be licensed in such proposed arrangement as is reasonably necessary for GNE to [*] with respect thereto. SG shall not be required to [*] of the third party from whom it has [*], and the business terms will be Confidential Information under this Agreement. GNE shall have up to [*] ([*]) [*], from the effective date of any notice from SG under this Section 5.6(a), to notify SG if GNE is [*] in the proposed territory. Notwithstanding the foregoing, SG shall [*] notice under this Section 5.6(a), nor shall [*] with any third party for a license to [*], prior to providing GNE with the [*] report on data from a [*] [*] of [*].

(b) if GNE sends a timely notice under Section 5.6(a) indicating its interest to negotiate with respect to [*], then the Parties agree to negotiate in good faith following such timely GNE notice, for [*] ([*]) [*] from effective date of GNE's notice to SG under Section 5.6(a). If the Parties do not reach agreement on the [*] for [*] in the proposed territory by the close of business on the expiration date of the [*] ([*]) [*] negotiation period (or such other date the Parties may have mutually agreed to, the "[*] Negotiation Deadline"), or if GNE does not exercise its right to negotiate under this Section 5.6 or fails to timely respond to the SG notice under Section 5(a) with respect to [*], then after the end of the applicable period SG shall be free to enter into an agreement granting such license rights in the proposed territory to the third party with respect to [*], provided, however, that the terms of such license are not more favorable to the third party than the [*] previously made by SG to GNE without SG [*] such [*] terms to GNE and providing GNE

with the opportunity to accept such [*]. Such [*] shall expire on the [*] ([*]) anniversary of the [*] Negotiation Deadline.

5.7 Exclusivity. Subject to the other terms of this Agreement, during the Term of this Agreement SG agrees that it shall not (alone or with partner(s)) commence development or commercialization of any pharmaceutical formulation containing SGN 11&12 which would be substantially competitive with a Licensed Product already in development or commercialization pursuant to this Agreement. Any such pharmaceutical formulation is referred to herein as a "Competing Product". For purposes of clarification but not limitation, a candidate molecule for development would not constitute a Competing Product hereunder if the parties reasonably agree that (i) it would not substantially compete with a Licensed Product already in development or commercialization pursuant to this Agreement, and (ii) it would be developed or commercialized for a significantly different indication than any indication for which an existing Licensed Product is being researched, developed, commercialized or used, and for which said different indication would yield in excess of $[100 million] in additional annual peak sales beyond that projected for the existing Licensed Product(s).

5.8 Compliance with BMS Agreement. With respect to the BMS Technology, GNE hereby agrees to comply with the covenants and conditions of the BMS Agreement set forth in Exhibit C hereto as if they were a party to the BMS Agreement.

Subject to the other terms of this Agreement, and as consideration to SG for the licenses and other rights granted to GNE under this Agreement, commencing as to each country in the Territory on the date of Commercial Introduction of the first Licensed Product in such country, GNE shall make royalty payments to SG with respect to Net Sales of each Licensed Product in such country by GNE and any sublicensee(s) (using the foreign currency exchange provisions of Section 4.6(b) to calculate worldwide Net Sales in U.S. Dollars), as follows:

(a) Subject to Section 6.2(b), for any Licensed Product containing a construct of the Antibody that SG prepares and provides to GNE, GNE shall pay a royalty of [*] percent ([*]%) of Net Sales.

(b) For any Licensed Product that has been humanized or substantially altered by GNE from SG's construct of the Antibodies (e.g., by affinity maturation, etc.), GNE shall pay a royalty of [*] percent ([*]%) of Net Sales.

6.3 Third Party Royalties. On a country-by-country basis, the royalties otherwise due and payable by GNE hereunder shall be reduced by an amount equal to [*] percent ([*]%) of the amounts GNE or any sublicensee must pay to any third party with respect to the development, manufacture, import or export, use or sale of any Licensed Product; provided, however, that in no event shall the royalty payments due and payable to SG be reduced by this Section 6.3 below [*] percent ([*]%) of Net Sales of such Licensed Product by GNE and any sublicensee(s) in such country; and provided, further, that for so long as there is no other product in the market in such country that interacts with the CD40 antigen and competes with the Licensed Product, the royalty payments due and payable to SG shall not be reduced by this Section 6.3 below [*] percent ([*]%) of Net Sales of such Licensed Product by GNE and any sublicensee(s) in such country. If GNE believes in good faith that there is a competing product, it shall give notice to SG of such conclusion and GNE's intention to offset royalties payable to SG pursuant to this Section 6.3 subject to a minimum royalty of [*] percent ([*]%). If SG disagrees with GNE's conclusion that there is a competing product, the dispute will be resolved in accordance with the provisions of Section 12.12.

6.4 Royalties payable by SG. In the event that SG terminates this Agreement pursuant to Section 3.3(c)(ii), or GNE terminates this agreement pursuant to Section 9.2 prior to the filing by GNE of an IND on a Licensed Product, SG shall owe GNE royalties on the Net Sales by SG or its licensees of any Product that would fall under the definition of Licensed Product hereunder as follows: (i) if SG utilizes a construct of an anti-CD40 antibody modified by GNE (identified in Section 6.2(b)), a [*]% royalty; (ii) if SG utilizes its own construct (identified in Section 6.2(a)) but GNE's cell line, a [*]% royalty; (iii) if SG does not utilize GNE's construct or cell line, but uses or incorporates any GNE Know-how, a [*]% royalty.

6.5 Payment of Royalties and Other Amounts.

(a) Mode of Payments. For purposes of determining when a sale of any Licensed Product occurs under this Agreement, the sale shall be deemed to occur on the later of: (i) the date the Licensed Product is shipped; or (ii) the date of the invoice to the purchaser of the Licensed Product. After the date of Commercial Introduction of the first Licensed Product, all royalty payments shall be made within ninety (90) days after the end of each calendar quarter in which such sales were deemed to occur. Such royalty payments shall be accompanied by a detailed statement for each country in the Territory in which sales of Licensed Products occurred in the calendar quarter covered by such statement, specifying: the gross sales (if available) and Net Sales in each country's currency; the applicable royalty rate under this Agreement; the royalties payable in each country's currency, including an accounting of deductions taken in the calculation of Net Sales; the applicable exchange rate to convert from each country's currency to U.S. Dollars under Section 6.5(b); and the royalties payable in U.S. Dollars. All payments hereunder shall be made free and clear of any taxes, duties, levies, fees or charges, except for withholding taxes (to the

extent applicable). GNE shall make any applicable withholding payments due on behalf of SG and shall promptly provide SG with written documentation of any such payment sufficient to satisfy the requirements of the United States Internal Revenue Service related to an application by SG for a foreign tax credit for such payment. All royalty payments hereunder shall be made to SG in U.S. Dollars by bank wire transfer in immediately available funds to the account designated by SG in writing to GNE from time to time.

(b) Foreign Currency Conversion. For sales of any. Licensed Product that occur in a currency other than U.S. Dollars, the quarterly royalty payment will be calculated as follows:

(A/B) × C = U.S. Dollars royalty payment on foreign currency sales, where

A = foreign currency "Net Sales" per quarter;

B = foreign exchange conversion rate, expressed in local currency per U.S. Dollar (using as the applicable foreign exchange conversion rate the average of the rate published in the western edition of the Wall Street Journal, or any other mutually agreed-upon source, for the last business day of the calendar quarter); and

C = the royalty rate applicable to such Net Sales under this Agreement.

(c) Restrictions on Payment. If by law, regulations or fiscal policy of a particular country in the Territory, remittance of royalties in U.S. Dollars is restricted or forbidden, written notice thereof will promptly be given to SG, and payment of the royalty shall be made by the deposit thereof in local currency to the credit of SG in a recognized banking institution designated by SG in writing. When in any country in the Territory the law or regulations prohibit both the transmittal and deposit of royalties on sales in such country, royalty payments shall be suspended for as long as such prohibition is in effect and as soon as such prohibition ceases to be in effect, all royalties that GNE would have been under an obligation to transmit or deposit but for the prohibition shall forthwith be deposited or transmitted to the extent allowable.

6.6 Equity Purchases.

(a) Initial Purchase. Subject to the other terms of this Agreement, and as consideration to SG for the licenses and other rights granted to GNE under this Agreement, GNE shall be obligated to purchase up to $2 million of preferred stock of SG in the first offering of such preferred stock to occur after the Effective Date; provided, however, that SG is not in material breach of this Agreement (or was not at time of termination); provided, further, that such offering is completed no later than the second anniversary of Effective Date; and provided, further, that in no event will GNE be required to purchase stock that would cause GNE to own, in the aggregate, more than 19.9% of SG's issued and outstanding capital stock. The purchase of stock contemplated by this Section 6.6 shall be effectuated by the Parties entering into a mutually acceptable stock purchase agreement on terms equivalent to those of the other investors taking part in such offering. Without limitation, the stock purchase agreement and related agreements shall contain: (i) full registration rights; (ii) transfer rights (subject to compliance with applicable securities laws); (iii) an anti-dilution provision to prevent erosion of purchase price in the event of another sale of equity, and; (iv) a right of first refusal to newly issued shares to maintain GNE percentage ownership (subject to the carve outs set forth in SG's Investor Rights Agreement in effect as of the Effective Date); and (v) other provisions that are customary or advisable for similar purchases of preferred equity; provided, however, that in the case of all of the foregoing terms, in no event will such terms and conditions be less favorable to GNE than the terms and conditions contained in SG's Certificate of Incorporation and Investor Rights Agreement in effect as of the Effective Date. GNE will be entitled to review and comment on the documents prepared in connection with the next equity financing and SG will consider such comments in good faith. SG shall provide GNE with audited and unaudited financial statements and other documents

reasonably requested by GNE (including SG's most recent private financing documents), in connection with the purchase of preferred equity.

(b) IPO Support. In addition to the foregoing, and subject to the other terms of this Agreement, GNE shall invest up to two million dollars ($2,000,000) in an initial public offering of common stock of SG, at the offering price to the public, provided, however, that this Agreement has not been terminated and that SG is not in material breach of its terms, and provided, further, that in no event will GNE be required to purchase stock that would cause GNE to own, in the aggregate, more than 19.9% of SG's issued and outstanding capital stock. In lieu of GNE's participation in such initial public offering, if prior to any such initial public offering GNE files an IND with regard to the Antibodies, SG shall have the option to cause GNE to invest said two million dollars ($2,000,000) in a private placement purchase of SG's stock; provided, however, that SG must exercise such option by written notice to GNE within 60 days of the filing date of such IND; and provided, further, that in no event will GNE be required to purchase stock that would cause GNE to own, in the aggregate, more than 19.9% of SG's issued and outstanding capital stock. [*]

6.7 Financial Record Keeping and Review.

(a) GNE Records. After the date of Commercial Introduction of the first Licensed Product, GNE shall keep for at least three (3) years following the end of the calendar year to which they pertain records of all sales of Licensed Products, in sufficient detail to permit SG to confirm the accuracy of GNE's royalty calculations.

(b) Review. Subject to the other terms of this Section 6.7(b), at the request of SG, upon at least fifteen (15) business days' prior written notice from SG to GNE, and at the expense of SG (except as otherwise provided below), GNE shall permit an independent certified public accountant selected by SG and reasonably acceptable to GNE to inspect (during regular business hours) the records required to be maintained by GNE under this Section 6.7 as provided herein. At SG's request hereunder (which shall not be made more frequently than once per year during the Term of this Agreement after the first Commercial Introduction of a Licensed Product and for three (3) years following expiration or termination of this Agreement), the accountant shall be entitled to review, the then-preceding three (3) years of GNE's records for purposes of verifying GNE's royalty calculations. In every case the accountant must have previously entered into a

confidentiality agreement with both Parties substantially similar to the confidentiality provisions of Article 8 and limiting the disclosure and use of such information to authorized representatives of the Parties and the purposes germane to this Section 6.7. Results of any such review shall be made available to both Parties. If any review reveals a deficiency in the calculation of royalties resulting in any underpayment by GNE, GNE shall promptly pay SG the amount remaining to be paid (plus interest thereon at a rate equal to two percent (2%) over the prime rate of interest as reported by Bank of America NT&SA in San Francisco, California from time to time), and if such underpayment is by ten percent (10%) or more, GNE shall pay all costs and expenses of the review.
