securities issued in such offering. This right will expire following the first round of bona fide equity investment in Atreca from a single investor or group of investors that includes at least one venture capital, professional angel, not-for-profit foundation, corporate or other similar institutional investor (other than Stanford) and that either (i) is at least $2,500,000 in size or (ii) involves the sale to outside investors of at least 25% of the shares outstanding after such round on a Fully-Diluted Basis, but will apply to all shares to be issued in such round.

7.5                   Future Offerings; Limitation on Right to Purchase. In any private offering of Atreca’s equity securities (or securities convertible into or exercisable for Atreca’s equity securities) in exchange for cash (or in satisfaction of debt issued for cash), Stanford may purchase for cash that number of the securities issued in such offering as is necessary for Stanford to maintain its pro rata ownership interest in Atreca on a Fully-Diluted Basis. For the avoidance of doubt: (i) any securities Stanford may acquire or have the right to acquire under Section 7.3 shall not reduce the number of securities Stanford may purchase under this Section 7.5; (ii) if both Section 7.4 and this Section 7.5 apply to an offering, the provision granting Stanford the superior rights will govern; and (iii) Stanford shall not be obligated to purchase under Section 7.4 or 7.5 any Atreca securities it has the right to acquire under Section 7.3.

7.6                   Purchase Terms and Procedures; Financial Information; Notices.

(A)                   In any offering subject to Section 7.4 or 7.5:

provides that no amendment to the rights specified in the preceding clauses (i), (ii) and (iii) will be effective without Stanford’s written consent;

(3)                     Stanford may elect to exercise its right of purchase, in whole or in part, by notice given to Atreca within 15 Stanford business days (i.e., days other than Saturdays, Sundays, and holidays or other days on which Stanford is officially closed) after receipt of Atreca’s notice; and

(4)                     If Stanford elects not to purchase, or fails to give an election notice within such period, Stanford’s purchase right will not apply to the offering if (and only if and to the extent) it is consummated within 90 days on the same or less favorable (to the investor) terms as stated in Atreca’s notice to Stanford.

(B)                   If there is a conflict between the terms of this Agreement and those of any Atreca investor rights or similar agreement to which Stanford is a party, this Agreement will prevail.

(D)                   In the event of the closing of a firm commitment underwritten public offering of Atreca’s common stock, the rights granted in Sections 7.4 and 7.5 will terminate (in addition to any earlier termination pursuant to their terms) immediately before such closing.

(E)                    Atreca shall furnish to Stanford, as promptly as reasonably practicable, Atreca’s annual financial statements and annual operating plan, including an annual report of the holders of Atreca’s capital stock and other securities, and such other information as Stanford may reasonably request from time to time for the purpose of valuing its interest in Atreca.

(F)                     Notwithstanding any notice provision in this Agreement to the contrary, any notice given under this Agreement that refers or relates to any of Section 7.3 through and including Section 7.7 shall be copied concurrently to ***@***; provided, however, that delivery of the copy will not by itself constitute notice for any purpose under this Agreement.

[*]           = Certain confidential information contained in this document, marked by brackets, has been omitted pursuant to Rule 406 of the Securities Act of 1933, as amended.

7.7                   Repurchase Obligation.

If Stanford is to conduct any clinical trial on behalf of Atreca or any agent of Atreca, Atreca will repurchase all Stanford’s equity interest in Atreca (whether or not acquired pursuant to this Agreement) and Stanford’s right to acquire Atreca securities under this Agreement will terminate upon the commencement of such trial. Atreca cannot begin any such trial until Stanford no longer holds any equity interest in Atreca. The repurchase price for any such equity interest will be the fair market value for that equity at the time Atreca and Stanford enter into a definitive agreement under which any such clinical research will be performed. Fair market value of publicly traded equity instruments will be determined by taking the average of the closing price for such equity over the five days preceding such date. Fair market value of non-public equity instruments will be at least as high as the greater of:

(A)                   the last value placed on any such equity in Atreca through an arms-length transaction regarding the issuance or sale of any equity in Atreca; or

(B)                   the last value placed on such equity by Atreca’s Board of Directors in good faith in connection with any transaction purporting to value such equity at fair market value, other than this repurchase of shares from Stanford.

7.8                   License Maintenance Fee. Beginning June 28, 2014 and each June 28 thereafter, Atreca will pay Stanford a yearly license maintenance fees as follows:

(A)                   $[*] on June 28, 2014 and June 28, 2015;

(B)                   $[*] each June 28 thereafter until the first commercial sale of a treatment Licensed Product;

(C)                   $[*] each June 28 thereafter.

Yearly maintenance payments are nonrefundable, but they are creditable each year as described in Section 7.12.

7.9                   Milestone Payments. Atreca will pay Stanford the following milestone payments:

(A)                   $[*] upon [*] as a [*];

(B)                   $[*] upon [*] for a [*];

(C)                   $[*] upon [*];

(D)                   Thereafter, $[*] upon [*].

Milestones will not be due for Licensed Products in Developing Nations.

7.10            Earned Royalty. Atreca will pay Stanford earned royalties ([*]%) on Net Sales as follows:

(A)                   [*]% of Net Sales for [*];

10

[*]           = Certain confidential information contained in this document, marked by brackets, has been omitted pursuant to Rule 406 of the Securities Act of 1933, as amended.

(B)                   [*]% of Net Sales for [*];

(C)                   [*]% of Net Sales for [*];

(D)                   [*]% of Net Sales for [*];

(E)                    [*]% of Net Sales for [*];

(F)                     [*]% of Net Sales for [*].

If the Licensed Product becomes non-exclusive for 7.10 (E), the amount due will be reduced by [*] ([*]%). Atreca will not receive any earned royalties from its work with the Bill and Melinda Gates Foundation, and therefore Stanford will also not receive any earned royalties from any Licensed Products that would otherwise fall under this Agreement.

7.11            Earned Royalty if Atreca Challenges the Patent. Notwithstanding the above, should Atreca bring an action seeking to invalidate any Licensed Patent, Atreca will pay royalties to Stanford at the rate of [*] percent ([*]%) of the Net Sales of all Licensed Products sold during the pendency of such action. Moreover, should the outcome of such action determine that any claim of a patent challenged by Atreca is both valid and infringed by a Licensed Product, Atreca will pay royalties at the rate of [*] percent ([*]%) of the Net Sales of all Licensed Products sold.

7.12            Creditable Payments. The license maintenance fee for a year may be offset against earned royalty payments due on Net Sales occurring in that year.

For example:

(A)                   if Atreca pays Stanford a $[*] maintenance payment for year Y, and
according to Section 7.10 $[*] in earned royalties are due Stanford for Net Sales in year Y, Atreca will only need to pay Stanford an additional $[*] for that year’s earned royalties.

(B)                   if Atreca pays Stanford a $[*] maintenance payment for year Y, and
according to Section 7.10 $[*] in earned royalties are due Stanford for Net Sales in year Y, Atreca will not need to pay Stanford any earned royalty payment for that year. Atreca will not be able to offset the remaining $[*] against a future year’s earned royalties.

7.13            Obligation to Pay Royalties. A royalty is due Stanford under this Agreement for any activity conducted under the licenses granted. For convenience’s sake, the amount of that royalty is calculated using Net Sales. Nonetheless, if certain Licensed Products are made, used, imported, or offered for sale before the date this

11

[*]           = Certain confidential information contained in this document, marked by brackets, has been omitted pursuant to Rule 406 of the Securities Act of 1933, as amended.

Agreement terminates, and those Licensed Products are sold after the termination date, Atreca will pay Stanford an earned royalty for its exercise of rights based on the Net Sales of those Licensed Products.

7.14            No Escrow. Atreca shall not pay royalties into any escrow or other similar account.

7.15            Currency. Atreca will calculate the royalty on sales in currencies other than U.S. Dollars using the appropriate foreign exchange rate for the currency quoted by the Wall Street Journal on the close of business on the last banking day of each calendar quarter. Atreca will make royalty payments to Stanford in U.S. Dollars.

7.16            Non-U.S. Taxes. Atreca will pay all non-U.S. taxes related to royalty payments. These payments are not deductible from any payments due to Stanford.

7.17            Interest. Any payments not made when due will bear interest at the lower of (a) the Prime Rate published in the Wall Street Journal plus 200 basis points or (b) the maximum rate permitted by law.

8                       ROYALTY REPORTS, PAYMENTS, AND ACCOUNTING

8.1                   Quarterly Earned Royalty Payment and Report. Beginning with the first sale of a Licensed Product by Atreca or a sublicensee, Atreca will submit to Stanford a written report (even if there are no sales) and an earned royalty payment within 30 days after the end of each calendar quarter. This report will be in the form of Appendix B and will state the number, description, and aggregate Net Sales of Licensed Product during the completed calendar quarter.
