  1.   OVERVIEW ================================================================================

The goal of this document is to provide a reasonably complete list of Yukon requirements for the Inktomi search service.  Note that a number of the requirements in this document are met by the existing search service but are included anyway for the sake of completeness.

The Section 2 lists all requirements according to area (Performance and Scalability, Reliability and Fault Tolerance, ...) together with information on Target Release and Due Date as defined below.  The Appendix (Section 7) follows a similar organization and provides more detail on the requirements..

                          OVER-UTILIZATION ADJUSTMENT

In the event that one party under-provisions its portion of the shared Inktomi hosting cluster such that its [*] are [*] by the [*], there will be a charge on a [*] levied against the under-provisioned party.

If [*] for a [*] exceeds its agreed capacity provisioning (as determined in accordance with Sections 2.2 and 2.8, then Microsoft's [*] will be [*] ([*] if the [*] is by [*], or [*] if such [*] is by [*]) in accordance with the following computation: [*] the [*] ([*]) times the [*] of the provisioned capacity ([*]). Note that the over-utilization could apply to [*] in any [*].

[*] will be calculated each month by taking the [*] of the Inktomi [*] without regard to [*] ([*]) [*] ([*]) [*] by the agreed total [*] provisioned.

[*] will be calculated for each party each month by [*] the number of [*] ([*] the [*] in the [*]) from the number of [*] for the [*].





Example:

     Assumptions:      1. Microsoft provisioned capacity is [*]      2. Inktomi provisioned capacity is [*]      3. [*] in [*] is $[*]      4. [*] is [*] for a [*]      5. [*] is [*] for that [*]

     [*] = $[*] = $[*]

     [*] = [*]  = [*]

     Over-Utilization Adjustment = [*] = $[*]              [*] in such [*] payable by [*]

Notwithstanding anything contained herein to the contrary, if a party shall have [*] its provisioned capacity by [*] in any month, such party shall be deemed [*] for its [*] during such month as soon as possible.

                                     EXHIBIT F                                    ---------

                              Transfer by Inktomi                               -------------------

If Inktomi requests Microsoft's consent to a transfer as described in clause (a) of Section 12.5 of this Software Hosting Agreement to which this Exhibit F is  appended, and Microsoft reasonably withholds its consent to such transfer (an  Unconsented Transfer), then Inktomi will nevertheless have the right to  transfer this Agreement in connection with its proposed Unconsented Transfer  subject to the following conditions precedent to the Unconsented Transfer:

(i)   Inktomi, at its sole cost and expense, and without any financing supplied by Microsoft, will create a separate cluster of Hosting Servers for Microsoft required to service Microsoft's reasonably anticipated needs for a period of twelve months after the commencement of operation of such new and relocated cluster [provided however that Microsoft will purchase, or fund (in accordance with the Loan Agreement) Inktomi's of, (whichever Microsoft elects) any new hosting servers beyond the Hosting Servers purchased by Inktomi under said Software Hosting Agreement necessary to service Microsoft's reasonably anticipated needs as set forth above];

(ii)  Inktomi will relocate, at its sole cost and expense (including, without  limitation, indemnifying Microsoft and holding it harmless against any and all  Taxes that arise as a direct or indirect result of the relocation of the Hosting Servers), all Hosting Servers referred to in clause (i) to a location designated by Microsoft, in its sole discretion;

(iii) Inktomi, at its sole cost and expense, will provide training to Microsoft  personnel to the extent requested by Microsoft, to enable such personnel to use  and maintain the Microsoft Search Engine, and to create enhancements thereto,  with reasonable competence (all as determined by Microsoft in its sole discretion);

(iv)  Inktomi will grant to Microsoft an irrevocable, non-exclusive,  royalty-free license to use the Product (and all required underlying Inktomi  Technology) solely in connection with Microsoft's operation of the Microsoft  Search Engine (which license shall include the right to create enhancements and  other derivative works based thereon for use in conjunction therewith) for such  period as Microsoft may require to transition its search engine services to  non-Inktomi technology (the Transition Period), and Inktomi will waive all  royalties otherwise payable pursuant to the Software Development Agreement  and/or the Information Services Agreement between the parties of even date  herewith; for the purposes of this clause (iv), the Transition Period will  commence at such time as Microsoft assumes control over said separate cluster  and begins itself operating the Microsoft Search Engine, and will continue  thereafter for eighteen months (18) or until the

                                      24

  termination of the Software Development Agreement and Information Services  Agreement (whichever is longer);

(v)   Inktomi will direct the Escrow Agent to release to Microsoft all Confidential Materials held by the Escrow Agent, subject to Microsoft's agreement to use such Confidential Materials only in connection with its licensed rights under clause (iv) above;

(vi)  Inktomi will agree to reimburse Microsoft for all reasonable costs incurred by Microsoft in transitioning its search engine to non-Inktomi technology (whether created by Microsoft or by a third party); and

(vii) Inktomi will cause the applicable proposed transferee of this Agreement to assume, jointly and severally with Inktomi, all of Inktomi's obligations  hereunder.

Microsoft will cooperate with Inktomi and use its reasonable best efforts so as





to enable Inktomi to satisfy the foregoing conditions precedent in a timely  manner. Upon satisfaction of the foregoing conditions precedent, this Software  Hosting Agreement shall be deemed terminated pursuant to Section 10.1. Upon  expiration of the Transition Period, all rights granted to Microsoft to use the  Product (other than Microsoft Technology, Joint Derivative Technology and the  Microsoft Derivative Technology) and/or any Inktomi Technology under the  transitional license referred to in clause (iv) or otherwise shall cease, and  Microsoft shall immediately return to Inktomi all Confidential Materials (and all copies thereof), provided however that, notwithstanding any provision of the Ancillary Agreements to the contrary, the undertaking by Inktomi to indemnify Microsoft and hold it harmless against Taxes as provided in clause (ii) above shall survive any such terminations.

activities contemplated or required of it by this Agreement; provided that in each case the Person to whom Confidential Information is being disclosed is subject to obligations of confidentiality and non-use with respect to such Confidential Information substantially similar to the obligations of confidentiality and nonuse of the receiving Party pursuant to this Section 12.1; and provided further, that each Party shall remain responsible for any failure by its attorneys, independent accountants and financial advisors, Affiliates, and its and its Affiliates' respective directors, officers, employees, consultants, advisors, actual or potential acquirers and permitted subcontractors, sublicensees and subdistributors, to treat such Confidential Information as required under this Section 12.1.

12.1.4 Each Party acknowledges that a Party in breach of any of its obligations under this Section 12.1 shall cause the non-breaching Party irreparable harm, for which monetary damages will be an inadequate remedy. Therefore, notwithstanding anything to the contrary in this Agreement in the event of any such breach, the non-breaching Party shall be entitled, in addition to any other remedy available to it under this Agreement, at law or in equity, to injunctive relief, including an accounting for profits, specific performance of the terms hereof and other equitable relief for such breach, without the posting of bond or other security.

Notwithstanding the foregoing any disclosure which is required by Applicable Law or the rules of the U.S. Securities and Exchange Commission or any securities exchange, as reasonably advised by the disclosing Party's counsel, may be made without the prior consent of the other Party, although, prior to any such legally required disclosure by a Party, such Party shall use reasonable efforts where practicable to give the other Party reasonable notice and an opportunity to comment on the proposed disclosure.

12.4 Publications. Except for disclosures permitted under this Agreement, if Xencor, its Affiliates, or its employee(s) or consultant(s) wishes to make a publication or presentation specific to the Product or which otherwise may reasonably contain Know-How, or other intellectual property, of Aimmune, Xencor must receive written approval, not to be unreasonably withheld, conditioned or delayed, from Aimmune at least [***] ([***]) days prior to submission for publication or presentation.

12.5 Use of Names. Except as otherwise set forth in this Agreement, neither Party shall use the name of the other Party in relation to this transaction in any public announcement, press release or other public document without the written consent of such other Party, which consent shall not be unreasonably withheld; provided, however, that subject to Section 12.3, either Party may use the name of the other Party in any document filed with any Regulatory Authority or Governmental Authority, including the Securities and Exchange Commission or the rules of any securities exchange.

12.6 Unauthorized Disclosure of Confidential Information. Each Party shall have a response plan in place for any disclosure of Confidential Information that is not authorized or otherwise permitted under this Agreement. Such plan shall include considerations of, among other things, notification, remediation and retrieval. In the event that a Party becomes aware of an unauthorized disclosure of Confidential Information, then such Party shall notify the other Party promptly in writing.

FOR IMMEDIATE RELEASE

Aimmune Licenses Exclusive Worldwide Rights to Xencor's XmAb®7195 for the Development of Next-Generation Food Allergy Treatments

BRISBANE, Calif. - February 5, 2020 - Aimmune Therapeutics, Inc. (Nasdaq: AIMT), a biopharmaceutical company developing treatments for potentially life-threatening food allergies, today announced it has obtained an exclusive worldwide license to develop and commercialize the investigational humanized monoclonal antibody XmAb®7195 from Xencor, Inc.

XmAb7195, which has been renamed AIMab7195, was originally developed by Xencor for the treatment of allergic asthma. It uses three distinct mechanisms of action to reduce blood serum IgE and suppress IgE-producing cells. Aimmune initially plans to develop AIMab7195 as an adjunctive treatment with select Characterized Oral Desensitized ImmunoTherapy (CODIT™) programs, including PALFORZIA™ , to explore treatment outcomes in patients with food allergies.

As we look to the future of food allergy treatments, we are excited to explore the potential of oral immunotherapy to achieve greater levels of desensitization - and perhaps even remission - when combined with adjunctive biologics that target immune pathways, said Jayson Dallas, M.D., President and CEO of Aimmune. In-licensing AIMab7195 demonstrates our commitment to enriching our pipeline and strengthening Aimmune's global leadership in the evolving therapeutic landscape of food allergy treatments.

Aimmune's focus, clinical success and regulatory expertise in food allergy demonstrate their capability to advance AIMab7195 with highly complementary CODIT pipeline programs to create new options for people living with food allergy, said Bassil Dahiyat, Ph.D., President and CEO of Xencor. AIMab7195 is designed to reduce levels of IgE, a key mediator of allergic response, and there is strong scientific rationale that this reduction would synergize with the activity of desensitization therapies.

Under the terms of the agreement, Aimmune will make an upfront payment to Xencor of $5 million in cash and $5 million in equity, equivalent to 156,238 newly issued shares of Aimmune common stock at $32.0025/share. Xencor also is eligible to receive up to $385 million based on the achievement of certain clinical development, regulatory and commercialization milestones — beginning with the initiation of a Phase 2 clinical trial — and is eligible to receive a high single-digit to mid-teen percentage of royalties upon commercialization of AIMab7195. Aimmune will be solely responsible for costs related to the development of AIMab7195 and plans to provide a development plan in the coming months.

About AIMab7195 (formerly XmAb®7195)

AIMab7195 is an anti-IgE monoclonal antibody with enhanced binding to the Fc gamma receptor IIb (FcyRIIb). IgE recognizes and interacts with allergens and, as a result, can activate immune cells, such as mast cells and basophils, that drive an allergic response

in patients. AIMab7195 is designed to clear IgE rapidly from circulation, to prevent the production of IgE by preventing the activation of IgE-positive B cells, and to block IgE from interacting with its receptor on immune cells. AIMab7195 has been evaluated in two Phase 1 studies that enrolled more than 100 healthy volunteers and patients with allergy and atopic disease.
