In exercising the rights and licenses granted under this Agreement, MedImmune shall have the right to have Adjuvant and/or Product in the Field researched, developed and/or made for MedImmune by a Third Party without granting a sublicense to such Third Party; provided, that such research and development is ***. The sublicense granted by IDC under this Section 2.1(a) to any IDC Patent Rights or IDC Know-How owned or controlled by a Third Party shall be subject to the applicable Technology Acquisition Agreement.

(b) In addition to the rights and licenses granted to MedImmune under this Agreement, IDC covenants that neither IDC nor its Affiliates has granted or will grant any rights or licenses under IDC Patents or IDC Know-How with respect to *** Product in the Field in the Territory nor will IDC or its Affiliates assist a Third Party with respect to research, development, manufacture, use, sale, offer for sale or importation of Adjuvant for use in a *** Product in the Field in the Territory, except that IDC has granted rights to a Third Party under a *** dated ***, as amended and provided, however that an acquiring entity and Affiliates of an acquiring entity in a Change of Control of IDC may provide assistance to a Third-Party with respect to research, development, manufacture, use, sale, offer for sale or importation of Adjuvant for use in a *** Product in the Field in the Territory with respect to Patent Rights or Know-How that are owned

***

or controlled by the acquiring entity or its Affiliates at the time of such Change of Control or Know-How that is developed thereafter that does not result from the use of IDC Know-How. IDC covenants and agrees that neither IDC nor its Affiliates will practice, use or exploit IDC Patents and/or IDC Know-How with respect to *** Product in the Field in the Territory except in carrying out its obligations hereunder. In the event of a Change of Control, IDC shall cause the acquiring entity and its Affiliates to agree for the benefit of MedImmune not to use any Know-How that results from the use of IDC Know-How for the research, development, manufacture, use, sale, or importation of *** Product in the Field in the Territory. The limitations in this Section 2.1(b) shall no longer apply in any country where the license granted in Section 2.1(a) has become non-exclusive or has been terminated.

(i) Provide to IDC the written reports as required by Section 3.1(d) of the IDRI Agreement.

(ii) Comply with the obligations of Section 3.4 of the IDRI Agreement.

(iii) *** shall defend, indemnify, and hold IDRI, its Affiliates, and their respective officers, directors, employees, and agents (the “IDRI Indemnitees”) harmless from and against any and all damages or other amounts payable to a Third Party claimant, as well as any reasonable attorneys fees and costs of litigation incurred by such IDRI Indemnitees (collectively, “IDRI Damages”), all to the extent resulting from claims, suits, proceedings or causes of action brought by such Third Party (“IDRI Claims”) against such IDRI Indemnitee based on or alleging: (a) the development, manufacture, storage, handling, use, promotion, sale, offer for sale, and importation of any IDRI Licensed Product by MedImmune or its Affiliates, Sublicensees, Third Party contractors, or distributors in the Territory; (b) the development, manufacture, storage, handling, use, promotion, sale, offer for sale, and importation of a Adjuvant by MedImmune or its Affiliates, Sublicensees, Third Party contractors or distributors in the Territory; (c) the willful misconduct or negligent acts of MedImmune, its Affiliates, or the officers, directors, employees, or agents of MedImmune or its Affiliates; or (d) any activities

***

conducted by or for MedImmune as part of Phase I Clinical Trials, Phase II Clinical Trials or Phase III Clinical Trials of IDRI Licensed Products. The foregoing indemnity obligation shall not apply if the IDRI Indemnitees materially fail to comply with the indemnification procedures set forth in Section 2.1(c)(iv), or to the extent that such IDRI Claim is based on or alleges: (i) the development, manufacture, storage, handling, use, promotion, sale, offer for sale, and importation of any product by IDRI or its Affiliates, sublicensees, or distributors in the Territory; or (ii) the willful misconduct or negligent acts of IDRI or its Affiliates, or the officers, directors, employees, or agents of IDRI or its Affiliates.

The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense of the Claim for which indemnity is being sought. The Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole expense; provided, however, the Indemnifying Party shall have the right to assume and conduct the defense of the Claim with counsel of its choice. The Indemnifying Party shall not settle any Claim without the prior written consent of the Indemnified Party, not to be unreasonably withheld, unless the settlement involves only the payment of money. So long as the Indemnifying Party is actively defending the Claim in good faith, the Indemnified Party shall not settle any such Claim without the prior written consent of the Indemnifying Party. If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, (a) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to the Claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (b) the Indemnifying Party will remain responsible to indemnify the Indemnified Party as provided in Section 2.1(c)(iii).

(v) MedImmune shall procure and maintain, and require Sublicensees to procure and maintain, insurance, including product liability insurance or self-insure, in an amount adequate to cover its obligations hereunder and which are consistent with normal

***

business practices of prudent companies similarly situated at all times during which any IDRI Licensed Product is being clinically tested in human subjects or commercially distributed or sold. It is understood that such insurance shall not be construed to create a limit on MedImmune’s liability with respect to its indemnification obligations under Section 2.1(c)(iii). MedImmune shall provide IDC with written evidence of such insurance upon request. MedImmune shall provide IDC with written notice at least *** days prior to the cancellation, non-renewal or material change in such insurance or self-insurance which materially adversely affects the rights of IDC hereunder.

Notwithstanding any representation or warranty in Article 7 or any other provision of this Agreement to the contrary, the federal government of the United States of America may have certain rights to such IDC Patent Rights as described in Chapter 18, Title 35 of the United States Code and accompanying regulations, including Part 401, Chapter 37 of the Code of Federal Regulation, as such may be amended. The Parties’ rights and obligations under this Agreement to any government-funded inventions, including the license set forth in Section 2.1(a) and any sublicense granted under Section 2.2, are subject to the applicable terms of the foregoing United States laws. If and to the extent required by applicable United States law, MedImmune agrees that Adjuvant and Product used or sold in the United States by MedImmune, its Affiliates or its Sublicensees will be manufactured substantially in the United States or its territories, subject to such waivers as required or obtained in advance from the U.S. government.

(e) With respect to each Technology Acquisition Agreement pursuant to which MedImmune is sublicensed under this Agreement, provided that MedImmune has a copy of the Technology Acquisition Agreement that includes the terms applicable to a sublicensee thereunder, MedImmune shall comply with such terms thereunder.

2.2 Within its sole discretion, MedImmune may grant exclusive or non-exclusive sublicenses (including the right to grant further sublicenses) under some or all of the rights and licenses granted to MedImmune under Section 2.1(a) of this Agreement to one or more entities (except as limited by any Technology Acquisition Agreement) subject to the following conditions: (a) each sublicense shall be subject to and consistent with the rights and licenses

***

granted under this Agreement; and (b) shall include an obligation of the Sublicensee to account for and report its sales of Products to MedImmune on the same basis as if such sales were Net Sales by MedImmune; (c) shall include (i) confidentiality and non-use obligations that require the Sublicensee to comply with confidentiality obligations with respect to IDC Know-How and Confidential Information of IDC similar to those of this Agreement; (ii) the obligations of Section 2.1 with respect to IDRI Licensed Product sublicensed to the Sublicensee; (iii) the obligations of Section 2.1 (d) with respect to Technology Acquisition Agreements sublicensed to the Sublicensee; (iv) the obligations of Section 2.9 with respect to notice as to Third Party Patent Rights; (v) the notice, joinder, cooperation/assistance and settlement obligations of Section 5.2(a), (c) and (e); (vi) the obligations to “abide” and “cooperate” of Section 5.3; (vii) the obligations of Section 6.2; (viii) the obligations of Section 7.6(b); (ix) the notice obligations of Section 7.7; and (x) the obligations of Section 7.8 with respect to Product sublicensed to the Sublicensee; (d) ***; and (e) ***.

2.5 IDC shall not perform any *** of *** Product in the Field in any human in any country without the prior written consent of MedImmune, which consent may be withheld in the sole discretion of MedImmune, during the period that the license granted under Section 2.1(a) is exclusive in such country.

2.6 MedImmune shall provide IDC with prompt written notice of any adverse events with respect to Product. IDC shall provide MedImmune with prompt written notice of any adverse events with respect to the Adjuvant and/or product that includes the Adjuvant known to IDC to the extent IDC has the right to disclose such information.

***

2.7 Except for the license granted under Section 2.1(a), MedImmune shall have no other license, implied or express, in or to the IDC Patent Rights or IDC Know-How.

2.8 MedImmune acknowledges that MedImmune has not been granted a license to sell or distribute the Adjuvant supplied by IDC for use pursuant to the license granted under Section 2.1(a) or *** under the license granted under Section 2.1(a) other than (i) for use in or as part of a Product for use in the Field or (ii) for producing a Product for use in the Field. MedImmune *** pursuant to the license granted under Section 2.1(a) or *** under the license granted under Section 2.1(a) ***.

2.9 During the Term, if IDC or MedImmune becomes aware of one or more Patent Rights of a Third Party that cover the Adjuvant or Adjuvant as part of the Product in the Field or the manufacture or use thereof, such Party shall promptly inform the other Party thereof. If IDC desires to obtain a license thereto, it shall promptly inform MedImmune as to such Patent Rights, and upon written request from MedImmune, IDC shall ***. Prior to entering into any such agreement under which IDC can sublicense to MedImmune, IDC shall provide MedImmune with a copy of such agreement or a description of the material terms. Within *** days after MedImmune receives such agreement, MedImmune shall notify IDC, in writing, as to whether MedImmune shall be sublicensed under such agreement. Upon such written notice from MedImmune that MedImmune is to be sublicensed under such agreement, such agreement when entered into by IDC shall automatically become a Technology Acquisition Agreement; provided that ***. Otherwise, such agreement shall not be a Technology Acquisition Agreement.

2.10 (a) Subject to Section 2.10(b), (c), and (d), MedImmune hereby grants to IDC *** to (i) ***, and (ii) *** from (i) above.

(b) The licenses granted under Section 2.10(a) with respect to Patent Rights that are in existence prior to termination or expiration of this Agreement shall be terminable only in the event that IDC fails to meet its indemnity obligations under this Agreement, which termination shall be in accordance with the termination provisions applicable to MedImmune under Section 9.3 of this Agreement.

***

(c) Notwithstanding Section 2.10(a), IDC shall not have the right to grant a Third Party a sublicense under MedImmune Licensed Patent Rights unless *** to *** a *** of such Third Party that is ***, which license is *** and is *** under this Agreement without any *** other than those *** under *** of this Agreement and with respect to other Technology Acquisition Agreements also under *** of this Agreement. The license granted under Section 2.10(a) does not include a right to enforce or defend MedImmune Licensed Patent Rights. For the avoidance of doubt, no license is granted under this Section 2.10 with respect to any Patent Rights that cover inventions that are made after termination of this Agreement without violation of Section 6.1, or after expiration of this Agreement, ***. IDC shall provide written notice to MedImmune of each sublicense including the name of the sublicensee and the scope of the license that is granted under MedImmune Licensed Patent Rights.

(d) In the event that MedImmune and/or its Affiliate or Sublicensee owes a Third Party a royalty or any other payment with respect to MedImmune Licensed Patent Rights licensed to IDC as a result of activities of IDC or its Affiliates or activities of any person or entity that is granted a sublicense thereunder by IDC or its Affiliates, then IDC shall reimburse MedImmune for such royalty or other payment; provided, that MedImmune has disclosed such royalty or other payment obligations in advance in writing and IDC elects in writing to receive license rights under such MedImmune Licensed Patents Rights for which a royalty or other payment obligation is owing. If IDC elects not to receive license rights under such Patent Rights, then the applicable Patent Rights shall be deemed excluded from MedImmune Licensed Patent Rights and from the license granted pursuant to Section 2.10(a).

***

MedImmune shall not be obligated to *** pursuant to this Section 3.1(a) until *** after the Effective Date; provided, however, that upon written notice from MedImmune to IDC prior to expiration of such *** that MedImmune elects to *** with respect to a Vaccine Product that includes an Adjuvant for use in the treatment and/or prevention of *** prior to *** with respect to Product, then MedImmune’s obligation to *** shall be *** to *** after the Effective Date.

(b) If, in any ***, MedImmune or its Affiliate(s) and/or a Sublicensee of MedImmune, and/or an entity performing work for or on behalf of or pursuant to a collaborative agreement with MedImmune alone or together, has performed *** of the following with respect to a Product, then MedImmune shall be deemed to have complied with MedImmune’s obligations under Section 3.1(a) with respect to Product in the United States:

***

For purposes of the foregoing, *** means ***, in each of the foregoing according to the approved ***, and *** means ***.

If, in a ***, MedImmune has not met *** with respect to a Product in the United States, the failure to meet such obligation shall not alone establish that MedImmune has not met MedImmune’s obligations under Section 3.1(a) with respect to a Product in the United States.

(c) Subject to Section 3.1(d), in the event that MedImmune has not performed *** during a *** with respect to a Product in the United States, and has failed to comply with the obligations of Section 3.1(a) in such *** with respect to a Product, IDC shall have the right *** to ***, provided that IDC provides to MedImmune written notice thereof within *** days after the end of the applicable ***, which notice shall describe the failure and the efforts needed to be taken by MedImmune to overcome the failure.

obligations. If a Party requests such arbitration, *** shall not *** unless in such arbitration there is a final determination that MedImmune has not met MedImmune’s obligation under Section 3.1(a) with respect to Product, in the applicable ***, and, in addition, in such *** none of *** has occurred with respect to Product and in addition, MedImmune subsequently fails to take the steps determined in the arbitration decision to satisfy its obligations under Section 3.1(a). For clarity, if an arbitrator determines that MedImmune has not satisfied its obligations under Section 3.1(a), then IDC shall not have the right to *** under Section 3.1(c) unless MedImmune fails to take steps determined in the arbitration decision to satisfy this obligation under Section 3.1(a).

(e) Subject to Section 3.4, MedImmune agrees to use Commercially Reasonable Efforts to, at its expense, develop one Product and obtain Regulatory Approval to sell one Product in *** and in ***, provided, however, that it is expressly understood that MedImmune will not be required to conduct registration trials intended for use for approval of a Product in *** until at least *** has transpired and in *** until at least *** has transpired, in each case, ***.

its obligations. If a Party requests such arbitration, this Agreement shall not *** pursuant to Section 3.1(e) or 3.2(b) unless (i) in such arbitration there is a final determination that MedImmune has not met its obligations under Section 3.1(e) or 3.2(a) and (ii) except as otherwise provided in Section 3.3, and in addition MedImmune subsequently fails to take the steps determined in the arbitration decision. For clarity, if an arbitrator determines that IDC has not satisfied its obligations under Section 3.1(e) or 3.2(a), then IDC shall not have the right to *** under Section 3.1(e) or 3.2(b) unless MedImmune fails to the take steps determined in the arbitration decision to satisfy this obligation under Section 3.1(e) or 3.2(a) as the case may be.

ARTICLE 4

PAYMENTS BY MEDIMMUNE AND IDC

4.1 MedImmune shall pay to IDC the amounts set forth in Appendix I.

4.2 (a) Subject to Sections 4.2(b), (c), (d), (f) and (g), MedImmune shall pay to IDC royalties on Net Sales of Products in the Territory in the amounts set forth below:


(i) Portion of Net Sales of Products in the Territory in a calendar year up to and including $***.	***	%
(ii) Portion of Net Sales of Products in the Territory in a calendar year above $* up to and including $*.	***	%
(iii) Portion of Net Sales of Products in the Territory in a calendar year above $***.	***	%

For the purposes of clarity, the royalty owed to IDC based on Net Sales is the royalty calculated under this Section 4.2(a) as reduced under Sections 4.2(c), (d), and (f).

(b) Royalties on Product under Section 4.2(a) shall commence in a country of the Territory as of the date of First Commercial Sale of any Product in such country and shall terminate on a country-by-country basis on the tenth anniversary of the First Commercial Sale of the first Product in such country, after which time there is no further royalty obligations with respect to any Product in such country, except that the royalty shall continue after such tenth anniversary in such country with respect to Product sold in such country which sale of Product in such country infringes (except for the license granted under this Agreement) a Valid Claim of an IDC Patent Right in such country but only for as long as such infringement exists. The termination of royalty payments under this Section 4.2(b) in a country shall not terminate the licenses granted to MedImmune in such country, however, the exclusive license granted for such country shall become a non-exclusive license for such country *** after termination of royalty payments in such country.

***

(c) If there are sales of Products in a country in which there are no Valid Claims of IDC Patent Rights licensed to MedImmune that are infringed in such country, then the royalty amount for Net Sales in that country(ies) shall be reduced by *** percent (***%), subject to Section 4.2(g). The reduction under this Section 4.2(c) shall be determined by first reducing the royalties calculated under Section 4.2(a) pursuant to Section 4.2(d).

(d) In the event that MedImmune or its Affiliates or Sublicensees owe and pay running royalties to a Third Party during a calendar quarter related to *** of *** Product in the Field in a country (a “Third Party Royalty”), then, *** percent (***%) of such Third Party Royalties owed and paid by MedImmune or its Affiliates or Sublicensees for sale of such Product in the Field for a calendar quarter shall be deducted against up to *** percent (***%) of any royalty payments calculated under Section 4.2(a) with respect to the sale of such Product in such country for the calendar quarter before taking into account the royalty reduction under Sections 4.2(c), subject to Section 4.2(g).

(e) IDC shall be solely responsible for making any and all payments that are due and payable under a Technology Acquisition Agreement in effect as of the Effective Date. IDC agrees to make all payments under a Technology Acquisition Agreement in effect as of the Effective Date when due including but not limited to milestone payments and royalties for sales of Product made by MedImmune and/or its Affiliates and/or their Sublicensees subject to MedImmune making payments as required herein. If, after the Effective Date, IDC or its Affiliates acquires or licenses intellectual property rights from a Third Party under a Technology Acquisition Agreement that are subject to a royalty or other payment obligation to the Third Party, then IDC shall promptly disclose to MedImmune the obligations owing to the Third Party (with a true and complete description of the payment obligations to the Third Party). Unless MedImmune elects in writing not to receive the license rights under the Technology Acquisition Agreement, it shall promptly reimburse IDC for any milestones, royalties or other amounts that become due and owing to the Third Party by reason of the exercise of the license by MedImmune or its Affiliates or Sublicensees with respect to the Third Party’s intellectual property rights. If MedImmune elects not to receive the license rights, then the Third Party’s intellectual property rights shall be deemed excluded from the license granted pursuant to Section 2.1(a) and the definitions of IDC Know-How and IDC Patent Rights, as the case may be. IDC covenants to use reasonable efforts to insure that such Technology Acquisition Agreements entered into after the date of this Agreement are ***.

***

(f) In the event that a Competing Product is sold in a country of the Territory that in such country does not infringe a Valid Claim of an IDC Patent Right in such country, then

(i) if in the *** in which sales of Competing Product is initiated in such country or in any *** thereafter the Net Sales of Product in such country is reduced by at least *** percent (***%) and less than *** percent (***%) of Net Sales of Product in the Base *** unless such reduction was a result of ***, then the royalties payable by MedImmune in such country for such Product after taking into account any applicable credits against royalties under Section 4.2(d) and after taking into account the Section 4.2(c) reductions shall be reduced by *** percent (***%) for that ***, subject to Section 4.2(g); and

(ii) if in the *** in which sales of Competing Product is initiated in such country or in any *** thereafter the Net Sales of Product in such country is reduced by at least *** percent (***%) of Net Sales of Product in the Base ***, unless such reduction was a result of factors unrelated to the Competing Product, then the royalties payable by MedImmune in such country for such Product after taking into account any *** under Section 4.2(d) and after taking into account the Section 4.2(c) reductions shall be reduced by *** percent (***%) for that calendar year, subject to Section 4.2(g).

(iii) The “Base ***” shall be for each country the *** that immediately precedes the *** in which Competing Product is first sold in such country. For the first *** in which a Competing Product is sold in a country, the determination of the reduction in Net Sales as compared to the Base *** shall be determined by multiplying the Net Sales for the Base *** and the Net Sales for the first *** in which the Competing Product is sold by a fraction having as the numerator the number of *** remaining in the applicable *** after the first sale of Competing Product and as a denominator ***.

In the event of a reduction under this Section 4.2(f) the reduction shall be applied on a Product-by-Product, country-by-country basis.

(iv) The reductions in this Section 4.2(f) shall be determined *** and if Net Sales return to prior levels of Net Sales in the Base ***, the reductions shall be eliminated or adjusted as the case may be. Further, the reductions shall cease to apply if the Competing Product is no longer sold in a country for which a reduction has been made.

***

(g) Notwithstanding the reductions set forth in Sections 4.2(c), (d) and (f), in no event shall the royalty amounts paid under this Agreement on a country-by-country, Product-by-Product basis be reduced by more than *** percent (***%) of the amount that would otherwise be due absent the application of the reductions in Sections 4.2(c), (d) and (f) and elsewhere in this Agreement.

(h) All payments required under this Article 4 shall be made in U.S. Dollars. For the purpose of computing the Net Sales of Products sold in a currency other than U.S. Dollars, such currency shall be converted from local currency to U.S. Dollars in accordance with the rates of exchange for the relevant month for converting such other currency into U.S. Dollars used by MedImmune’s internal accounting system.

(i) Only one royalty shall be due hereunder with respect to the same unit of Product and no further royalty or other payment is due to IDC for subsequent transfer or use of a unit of Product for which royalties have been paid under this Agreement. Except as provided in Section 4.2(j), such royalty shall be payable on first sale of Product.

(j) No royalties shall be due upon the sale or other transfer of Product among MedImmune or its Affiliates, but in such cases the royalty shall be due and calculated upon MedImmune’s or its Affiliates Net Sales to the first Third Party.

(k) In the event that MedImmune grants a sublicense to a Third Party under this Agreement with respect to Product prior to ***, and for such sublicense MedImmune receives payments in addition to royalty payments (“Sublicense Payments”), MedImmune shall pay to IDC *** percent of the difference between (i) such Sublicense Payments and (ii) the portion of such Sublicense Payments attributable to *** for Product.

(l) In the event that a Technology Acquisition Agreement in effect as of the Effective Date is terminated, or the scope of the license thereunder is reduced and MedImmune was not responsible for making payments thereunder pursuant to Section 4.2(e), and MedImmune obtains a license under one or more Patent Rights and/or Know-How that was previously sublicensed to MedImmune thereunder, MedImmune shall have the right to deduct such payments from any payments owed by MedImmune to IDC after deducting any and all amounts that are deductable or creditable under this Agreement.

***

4.3 During the Term, following the First Commercial Sale of a Product in a country of the Territory, MedImmune shall furnish to IDC a quarterly written report for each calendar quarter showing the Net Sales and calculation thereof for each Product in each country during the reporting period, applicable royalty deductions for each Product in each country and the royalties payable under this Agreement for each Product in each country. Reports shall be due on the *** day following the close of each calendar quarter. Royalties shown to have accrued by each royalty report shall be due and payable on the date such royalty report is due. MedImmune shall keep complete and accurate records in sufficient detail to enable the royalties payable hereunder to be determined provided however, such obligation shall terminate with respect to each calendar quarter *** after the end of such calendar quarter.

4.4 (a) Upon the written request of IDC and not more than *** in each calendar year, and upon at least *** days prior written notice, MedImmune shall permit an independent certified public accounting firm of nationally recognized standing selected by IDC and reasonably acceptable to MedImmune, at IDC’s expense, to have access during normal business hours to such of the records of MedImmune as may be reasonably necessary to verify the accuracy of the royalty reports and payments hereunder for any or all of the *** preceding the calendar quarter in which the request is made. The accounting firm shall disclose to IDC and MedImmune only whether the royalty reports, are correct or incorrect and the amount of any discrepancy. No other information shall be provided to IDC. IDC shall provide MedImmune with a copy of such report within *** after receipt thereof. To the extent that a Technology Acquisition Agreement requires MedImmune as a sublicensee thereunder to permit the licensor of IDC to have access to the books and records of MedImmune or its Affiliate, MedImmune shall make such books and records accessible for inspection by such licensor.

(b) If such accounting firm identifies a discrepancy made during such period, the appropriate Party shall pay the other Party the amount of the discrepancy within *** of the date IDC delivers to MedImmune such accounting firm’s written report so concluding, or as otherwise agreed upon by the Parties or within its discretion, MedImmune may offset any such overpayment against payments due under this Agreement. The payment of the amount of the discrepancy will bear interest at an annual rate of interest equal to the ***, calculated on the

***

number of days such payment is delinquent. The fees charged by such accounting firm shall be paid by IDC unless the underpayment exceeded *** percent (***%) of the amount owed by MedImmune to IDC for the period audited, in which case, MedImmune shall pay to IDC the reasonable fees and costs charged by such accounting firm.

(c) MedImmune shall include in each sublicense granted by it pursuant to this Agreement a provision requiring the Sublicensee to make reports to MedImmune, to keep and maintain records of Net Sales made pursuant to such sublicense and to grant access to such records by IDC’s independent accountant to the same extent required of MedImmune under this Agreement.

(d) Upon the expiration of *** following the end of any ***, the *** payable with respect to such *** and all prior *** shall be ***, and *** shall be *** with respect to *** for such ***.

4.5 IDC shall treat all financial information subject to review under this Article 4 in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with MedImmune or its Sublicensees obligating it to retain all such information in confidence pursuant to such confidentiality agreement.

4.6 IDC alone shall be responsible for paying any and all taxes (other than withholding taxes required to be paid by MedImmune) levied on account of, or measured in whole or in part by reference to, any payments made by MedImmune to IDC under this Agreement. If provision is made in law or regulation of any country of the Territory for withholding of taxes of any type, levies or other charges with respect to any amounts payable hereunder to IDC, MedImmune (“Withholding Party”) shall promptly pay such tax, levy or charge for and on behalf of IDC to the proper governmental authority, and shall promptly furnish IDC with a receipt for such payment. The Withholding Party shall have the right to deduct any such tax, levy or charge actually paid from payment due IDC or be promptly reimbursed by IDC if no further payments are due the Withholding Party. The Withholding Party agrees to assist IDC in claiming exemption from such deductions or withholdings under double taxation or similar agreement or treaty from time to time in force and in minimizing the amount required to be so withheld or deducted. The Withholding Party shall apply the reduced rate of withholding,

***

or dispense with withholding, as the case may be, provided that the Withholding Party has received evidence, in a form satisfactory to the Withholding Party, of IDC’s delivery of all applicable forms (and, if necessary, its receipt of appropriate governmental authorization) at least *** prior to the time that the payment is due.

IDC shall have the first right within its sole discretion, but not the obligation, to control the defense thereof with attorneys selected by IDC, at the cost and expense of IDC. IDC shall promptly notify MedImmune as to whether IDC shall defend such action and if MedImmune does not receive such notice, MedImmune shall have the right but not the obligation to defend such action. The defending Party shall not settle or compromise such an action or proceeding in a manner that materially adversely affects the scope, validity or enforceability of any IDC Patent Rights in the Territory without the written consent of the other Party, which consent shall not be withheld unreasonably. If a defending Party is unable to defend such action solely in its own name, the other Party shall join such action voluntarily and shall execute and cause its Affiliates and sublicensees to execute all documents necessary for the defending Party to defend such action. The defending Party shall keep the other Party reasonably informed of the course of such action.

5.6 Except to the extent precluded by any Technology Acquisition Agreement, IDC and MedImmune shall jointly own Inventions and Know-How made jointly by one or more employees or contractors of IDC or its Affiliates and one or more employees or contractors of MedImmune or its Affiliates in connection with this Agreement and the intellectual property rights therein (“Joint Inventions”). Joint Inventions shall be licensed to MedImmune under Section 2.1 of this Agreement to the extent useful to research, develop, use, manufacture, sell, offer for sale, or import Adjuvant in the Field and/or a combination of Adjuvant and Vaccine Product for use in the Field. Except as exclusively licensed herein, each Party shall have the right to license or grant rights to Joint Inventions and the intellectual property rights therein for research, commercial and other purposes without the consent of the other Party or a duty to account to the other Party.

5.7 For the purposes of Sections 5.4, 5.5 and 5.6 the making of any Invention shall be determined in accordance with U.S. patent laws.

***

(c) Any combination of features or disclosures shall not be deemed to fall within the foregoing exclusions merely because individual features are published or available to the general public or in the rightful possession of the receiving Party unless the combination itself is published or available to the general public or in the rightful possession of the receiving party.

(d) If a Party is required by law or regulation (including, without limitation, regulations of the Securities and Exchange Commission and the U.S. Food and Drug Administration) or judicial or administrative process to disclose Confidential Information that is subject to the non-disclosure provisions of this Section 6.1, to the extent that such Party is not prohibited by applicable law from doing so, such Party shall promptly inform the other Party of the disclosure that is being sought in order to provide the other Party an opportunity to challenge or limit the disclosure obligations. Confidential Information that is disclosed by law or regulation or judicial or administrative process shall remain otherwise subject to the confidentiality and non-use provisions of this Section 6.1, and the Party disclosing Confidential Information pursuant to law or court order shall, except where impracticable, take all steps reasonably necessary, including without limitation obtaining an order of confidentiality, to ensure the continued confidential treatment of such Confidential Information.

6.2 (a) At least *** prior to the submission to any outside person for publication of a manuscript or prior to any oral public disclosure describing scientific data with respect to Adjuvant or Product in the Field, MedImmune or IDC, as the case may be, shall disclose to the other Party, as the case may be, the disclosure or manuscript to be made or submitted, and shall allow at least *** to allow the other Party to determine whether such disclosure or manuscript contains Confidential Information that should not be disclosed and/or permit MedImmune or IDC to determine whether such disclosure or manuscript contains subject matter for which patent protection should be sought prior to publication or disclosure or which MedImmune or IDC believes should be modified to avoid regulatory or commercial difficulties.

(b) After the expiration of *** from the date of mailing such disclosure or manuscript to a Party, unless MedImmune or IDC, as the case may be, has received from the other the written notice specified below, the authoring Party shall be free to submit such manuscript for publication or to publish the disclosed research results in any manner consistent with academic standards.

(c) Prior to the expiration of the *** period specified in this Section 6.2, a Party may notify the submitting Party of its determination that such oral presentation or manuscript contains Confidential Information of such Party or may notify the other Party that it contains material for which patent protection should be sought and/or material that will cause regulatory or commercial difficulties. The notified Party shall withhold its proposed public disclosure and confer with the designated contact of the other Party to determine the best course of action to take in order to modify the disclosure or to obtain patent protection. After resolution of the regulatory or commercial issues, or the filing of a patent application or due consideration as to whether a patent application can reasonably be filed and the outcome of such consideration is mutual agreement that a patent application should not be filed, then the submitting Party shall be free to submit the manuscript and/or make its public oral disclosure. Notwithstanding anything to the contrary in this Section 6.2, if the publication contains information that a Party reasonably determines is Confidential Information of such Party subject to the confidentiality obligations of this Article 6, then upon written notice to the other Party such information shall be deleted from any publication.

6.3 (a) Neither Party shall disclose the terms of this Agreement except either Party shall be permitted to disclose the terms of this Agreement to the extent required, in the reasonable opinion of such Party’s legal counsel, to comply with applicable laws, rules or regulations, including without limitation the rules and regulations promulgated by the United States Securities and Exchange Commission (“SEC”) or any other governmental agency. Notwithstanding the foregoing, before disclosing this Agreement or any of the terms hereof pursuant to this Section 6.3(a), the Parties will consult with one another on the terms of this Agreement for which confidential treatment will be sought in making any such disclosure. If a Party wishes to disclose this Agreement or any of the terms hereof in accordance with this Section 6.3(a), such Party agrees, at its own expense, to seek confidential treatment of the portions of this Agreement or such terms as may be reasonably requested by the other Party, provided that the disclosing Party shall always be entitled to comply with legal requirements, including without limitation the requirements of the SEC or any other governmental agency.

Immune Design Corp. Grants Adjuvant License to MedImmune

Seattle, WA, September 27, 2010 - Immune Design Corp. (IDC), a privately held biotechnology company developing novel vaccines and immunotherapies for infectious disease and cancer, announced today that it has entered into a license and development agreement with MedImmune for the use and commercialization of IDC’s proprietary Glucopyranosyl Lipid Adjuvant (GLA) as a component in vaccines for select infectious diseases.

“We are pleased to enter into this license with MedImmune as one of the world’s leading vaccine research-based pharmaceutical and healthcare companies,” commented IDC Executive Chairman Dr. ▇▇▇▇▇ ▇▇▇▇▇▇. “This relationship fits very well with IDC’s business model to advance the development of GLA and enable innovative vaccine products that we believe will provide significant benefit in areas of unmet need while maintaining our commitment to global access.”

Under the terms of the license agreement, IDC grants MedImmune exclusive worldwide rights to research, develop, use, and commercialize the GLA adjuvant in vaccines for specific indications. In return, IDC will receive an upfront licensing fee and potential development, regulatory and commercial milestones totaling $212M, in addition to royalty payments on sales of marketed products.

GLA is a toll-like receptor 4 (TLR-4) agonist which IDC has advanced into early clinical stage development. The small molecule adjuvant has several important features including a pure synthetic composition with straightforward manufacturing and long term stability, a rational design for optimal activation of human dendritic cells, compatibility with antigens in multiple formulations, and a well established safety profile.
