EXCLUSIVE START-UP LICENSE AGREEMENT

This Exclusive License Agreement (this “Agreement”), effective as of the date of last signature (the “Effective Date”), is made and entered into between the University of Washington, a public institution of higher education and an agency of the state of Washington, (“University”), and Neoleukin Therapeutics, Inc., a corporation organized under the laws of the state of Delaware (“Company”).

BACKGROUND

A. Certain innovations relating to the de novo design of cytokine mimics (University reference number 48337; Stanford University reference S18-238) were collaboratively made in (i) the University laboratory of Dr. Xxxxx Xxxxx (“Principal Investigator”), a University faculty member in the Department of Biochemistry and an employee of the Xxxxxx Xxxxxx Medical Institute (“HHMI”), and (ii) in the Stanford University laboratory of Dr. Xxxxx Xxxxxx, a Stanford University faculty member in the Department of Molecular and Cellular Physiology (at Stanford University) and an employee of HHMI. In addition, certain innovations relating to [***] neoleukin-2/15 variants for [***] and targeted IL-2 receptor binding (University reference number 48351) and de novo IL-2 antagonist (University reference number 48465) were made in the University laboratory of Dr. Xxxxx Xxxxx.

B. HHMI assigned its rights in such innovations (such rights via Xx. Xxxxx) to University and its rights in such innovations (such rights via Xx. Xxxxxx) to Stanford University, each assignment subject to the HHMI License (as defined herein). University and Stanford University thus co-own certain intellectual property rights in such innovations (University reference number 48337; Stanford University reference S18-238) , as listed in Exhibit A “Start-Up License Schedule” to this Agreement. University and Stanford University have executed an interinstitutional agreement (“IIA”), dated August 14, 2018, that authorizes University to assume sole responsibility for both the patent prosecution and licensing of co-owned patent applications. University has shared a copy of the IIA with Company under the confidentiality terms of the Option (as defined in Section 13.21). In addition, University solely owns certain intellectual property rights in innovations made in the course of University research relating to [***] neoleukin-2/15 variants for [***] and targeted IL-2 receptor binding (University reference number 48351) and de novo IL-2 antagonist (University reference number 48465), as listed in Exhibit A “Start-Up License Schedule” to this Agreement. Thus, University has the right to license to others certain rights to use and practice such intellectual property. University is willing to grant those rights so that such innovations may be developed for use in the public interest.

C. Company desires that University grant it an exclusive license under such intellectual property rights, and University is willing to grant such a license, on the terms set forth in this Agreement.

“Event of Force Majeure” means an unforeseeable act that prevents or delays a Party from performing one or more of its duties under this Agreement and that is outside of the reasonable control of the affected Party. An Event of Force Majeure includes acts of war or of nature, insurrection and riot, and labor strikes. An Event of Force Majeure does not include a Party’s inability to obtain a Third Party’s consent to any act or omission, unless the inability was caused by a separate Event of Force Majeure.

“Fair Market Value” means the average price at which the stock in question is publicly trading for twenty (20) days prior to the announcement of its purchase by the Sublicensee(s), or, if the stock is not publicly traded, the value of such stock as determined in good faith by the board of directors of Company or Sublicensee.

On sales of Licensed Products by made in other than an arm’s length transaction, the value of the Net Sales attributed to such transaction will be equal to the Net Sales that which would have been received in an arm’s length transaction, based on sales of like quantity and quality of Licensed Products sold on or about the time of the transaction. Net Sales does not include sale, lease, disposition or other transfer of Licensed Products among or between Company, Subsidiaries and Sublicensees for the purpose of subsequent resale to a Third Party, but does include subsequent resale to such Third Party. For avoidance of doubt Net Sales are calculated on sales by Company or Sublicensee to Distributor, and not on the subsequent sale by Distributor.

If, on a country-by-country basis, the other product, component or ingredient or service in the Combination Product is not sold separately in said country, Net Sales for the purpose of determining running royalties of the Combination Product shall be calculated by multiplying actual Net Sales of the Combination Product by the fraction A/C where “A” is the Net Sales price of the Licensed Product, if sold separately, and “C” is the Net Sales price of the Combination Product. If, on a country-by-country basis, neither the Licensed Product, nor the other product, component or ingredient or service in the Combination Product, is sold separately in said country, Net Sales for the purpose of determining running royalties of the Combination Product shall be determined in good faith by the Parties.

3. RIGHTS OF UNIVERSITY; LIMITATIONS

3.1 University’s Rights. University reserves all rights not expressly granted to Company under this Agreement. University retains for itself, Stanford University, and other not-for-profit academic research institutions, an irrevocable, nonexclusive license to practice Licensed Rights for academic research, instructional, or any other academic or non-commercial purpose. University retains for itself an irrevocable, nonexclusive license to practice Licensed Rights for clinical purposes. Expressly included within University’s reservation of rights is to do the following in connection with academic research, instructional, or any other academic or non-commercial purposes: (a) to use the Licensed Rights in sponsored research or collaborative research with any Third Party, but not for any commercial purpose, and only to the extent that no such Third Party is granted any commercialization rights of any kind under the Licensed Rights or to commercialize Licensed Products, (b) to grant material transfer agreements to the extent that the use of such materials is restricted to academic research, teaching and or other scholarly activities, and (c) to publish any information included in the Licensed Rights or any other information that may result from University’s or Stanford University’s research. For the avoidance of doubt, nothing in this Section 3.1 or elsewhere in this Agreement is intended to or shall be construed to alter, restrict, or limit the HHMI License.

3.2 Sublicensing Opportunities. If a Third Party notifies University that it wishes to license any of the exclusively licensed Licensed Rights in any field or territory in which Company is unable or unwilling to develop and market a Licensed Product, University will notify Company of such Third Party’s wish to obtain such license, and Company will have good faith discussions with such Third Party regarding the terms and conditions under which such Sublicense could be obtained. Company will not be obligated to provide such sublicense where it interferes with Company’s (or its Sublicensee’s) business strategy; however, Company will not unreasonably withhold such Sublicense.

3.3 Reservation of Rights for Humanitarian Purposes. Consistent with 35 U.S.C. §200 et seq., University retains the right to require Company to grant Sublicenses to responsible applicants in the Field of Use under the Licensed Patents on terms that are reasonable under the circumstances; or, if Company fails to grant a license, to grant the license itself. The exercise of these rights by University will only be in exceptional circumstances and only if University determines (a) the action is necessary to meet health or safety needs that are not reasonably satisfied by Company; or (b) the action is necessary to meet requirements for public use specified by federal regulations, and such requirements are not reasonably satisfied by Company, and (c) the action will not have a significant negative effect on Company’s (or its Sublicensee’s) business strategy with respect to the Licensed Products. University will not require the granting of a sublicense, and will not grant the license itself, unless the responsible applicant has first negotiated in good faith with Company. Company shall be entitled to use the dispute resolution mechanisms of Section 13.4 “Escalation; Dispute Resolution”, including seeking an injunction from the court if mediation is unsuccessful, if Company wishes to dispute that University should be entitled to exercise its rights under this Section 3.3.

4. APPLICATIONS AND PATENTS

4.1 Pre-Agreement Patent Filings. Company has reviewed the Licensed Patents and as of the Effective Date is not aware of any basis to challenge or dispute the inventorship, validity, or enforceability of any of the claims made in the Licensed Patents.

CONFIDENTIAL

4.2 Patent Prosecution Decisions. University and Company will consult on the preparation, filing and prosecution of the Licensed Patents (including, without limitation, on the selection of patent counsel). Patent counsel will be directed to deliver to Company all written and electronic communications to and from all patent offices and foreign counsel, and provide summaries of oral communications with patent offices. Provided Company is in compliance with Section A3.8 “Patent Expense Payment” of Exhibit A “Start-Up License Schedule”, Company’s directions regarding patent preparation, filing and prosecution will be followed unless detrimental to University’s intellectual property rights. University and Company will consult prior to deciding in which countries to pursue patent protection and provided Company is in compliance with Section A3.8 “Patent Expense Payment”, patents will be filed in all countries Company designates. University acknowledges the key role and value of the Licensed Patent portfolio to Company and the need for timely review and exchange of information between University and Company prior to Licensed Patent portfolio decisions. University will remain the client of record, and may at its own expense instruct patent counsel to take actions necessary to protect University’s intellectual property rights, if in University’s reasonable opinion, Company actions will result in a loss of rights; provided that for any such actions, if Company declines to reimburse University pursuant to Section A1.1 “Licensed Patents”, those applications and resultant patents will not be subject to this Agreement. In no event will Company file a patent application where all of the inventors are under University policy obligated to assign their rights in such patent application to University.

4.3 Assumption of Patent Prosecution and Maintenance. Provided Company is in compliance with Section A3.8 “Patent Expense Payment” of Exhibit A “Start-Up License Schedule”, University will take all commercially reasonable steps to cause patents and patent applications within the Licensed Patents to be diligently prosecuted and maintained. If Company is in compliance, and University, against Company’s instructions, decides to abandon or allow to lapse any patent application or any claim of any patent included in the Licensed Patents or not pursue patent protection for any foreign patent mutually agreed upon by the Parties under Section 4.2 “Patent Prosecution Decisions”, University will notify Company at least sixty (60) days before such decision would be effective, and Company will have the right to file, prosecute, and maintain, as applicable, such patent or patent application in University’s name at Company’s expense provided Company shall keep University informed of such activity. Company may thereafter abandon or allow to lapse any or all patents or patent applications for which it is responsible. Company will notify University of any abandoned or lapsed patents at least thirty (30) days prior to such abandonment or lapse.

5. COMMERCIALIZATION

5.1 Performance Milestones. Company will, directly or through its Subsidiaries or Sublicensees, use its commercially reasonable efforts, consistent with sound and reasonable business practices and judgment, to commercialize the inventions claimed in the Licensed Rights and to make and sell Licensed Products as soon as practicable and to maximize sales thereof. Unless an extension is provided due to an Event of Force Majeure during the term of this Agreement, Company shall perform, or shall cause to happen or be performed, the Performance Milestones in accordance with the Performance Milestone Dates. Upon the occurrence of an Event of Force Majeure, the Performance Milestones and Performance Milestone Dates shall be equitably adjusted to accommodate the Event of Force Majeure.

CONFIDENTIAL

5.2 Renegotiation of Performance Milestones. If Company determines that it will be unable to achieve a Performance Milestone, Company will so notify University in advance of the Performance Milestone Date, Company may request a Performance Milestone Extension (as described below) or, providing Company demonstrates it is diligently pursuing development and commercialization of at least one Licensed Product, Company may request that the Parties negotiate an appropriate new Performance Milestone and/or related Performance Milestone Date in good faith. If the Parties are unable to agree on a renegotiated Performance Milestone within sixty (60) days after commencing negotiations, University may proceed with its termination rights under Section 9.2 “Termination by University”, subject to both Company and University having the right to seek mediation under Section 13.4 “Escalation; Dispute Resolution”. In addition, if for any reason Company will be unable to achieve a Performance Milestone, then upon written notice to University and payment of [***] US dollars ($[***]), the timing for the Performance Milestone will be extended for one (1) year (“Performance Milestone Extension”) (and the timing for each subsequent Performance Milestone will likewise be extended for one (1) year. Company shall have the right to three (3) Performance Milestone Extensions by providing such notice and paying such fee. In the case that Company is unable to achieve a Performance Milestone (after any extensions provided for above) and University proceeds with its termination rights under Section 9.2 “Termination by University”, University will only have the right to terminate the particular performance category (e.g. agonist protein biologic, [***] molecular entity, or antagonist protein biologic) for such failed Performance Milestone, with such termination effectively removing such performance category from the Field of Use, and the Agreement would continue with respect to the other performance categories.

5.3 Commercialization Reports. Throughout the term of this Agreement and during the Sell-Off Period, and within [***] of December 31^st of each year, Company will deliver to University written reports of Company’s and Sublicensees’ efforts and plans to develop and commercialize the innovations covered by the Licensed Rights and to make and sell Licensed Products.

Company will not settle any suits or actions in any manner relating to the Licensed Rights without obtaining the prior written consent of University, which consent shall not be unreasonably withheld or delayed; provided, however, that the Parties agree that loss of University’s intellectual property rights is a reasonable reason to withhold consent.

The scope of the direct license, the licensed territory, and the duration of the license grant will be comparable to the corresponding terms granted by Company to such Sublicensee, provided that such Sublicensee will be granted at least the same scope of rights as it obtained from Company under its Sublicense. For the sake of clarity, the financial terms, including without limitation, the running royalty rate and milestone payments, will be identical to the corresponding financial terms set forth in this Agreement, provided University shall consider in good faith reducing the non-running royalty financial payments where there are multiple direct licensees or such direct licensee has a reduced scope compared with this Agreement. Notwithstanding the foregoing, each Sublicensee’s right to enter into such direct license will be conditioned upon:

Except as set forth in Subsection 9.8.5 “Time Limitations”, University may, at its sole discretion, waive any of these requirements. If all of the conditions set forth in this Section 9.8 are met, then Sublicensee will be granted such direct license by University. If any condition set forth in this Section 9.8 is not met, then after expiration of any time period granted to Sublicensee with respect to meeting such condition (for example and to the extent applicable, the Initial Notice Period and/or the periods described in Subsections 9.8.4 “Sublicensee Certification that Conditions are Satisfied” and 9.8.5 “Time Limitations”), Sublicensee will not practice Licensed Rights except as provided for in Section 9.6 “Effect of Termination” and University will be free to license or not license Licensed Rights to such Sublicensee according to University’s sole discretion.

HHMI, and its trustees, officers, employees, and agents (collectively, “HHMI Indemnitees”), will be indemnified, defended by counsel acceptable to HHMI, and held harmless by Company from and against any claim, liability, cost, expense, damage, deficiency, loss, or obligation, of any kind or nature (including, without limitation, reasonable attorneys’ fees and other costs and expenses of defense) (collectively, “HHMI Claims”), based upon, arising out of, or otherwise relating to this Agreement or any Sublicense or Permitted Sublicense, including without limitation any cause of action relating to product liability. The previous sentence will not apply to any HHMI Claim that is determined with finality by a court of competent jurisdiction to result solely from the gross negligence or willful misconduct of an HHMI Indemnitee. Notwithstanding any other provision of this Agreement, Company and Sublicensee’s obligations to defend, indemnify and hold harmless the HHMI Indemnitees under this paragraph will not be subject to any limitation or exclusion of liability or damages or otherwise limited in any way.

If (a) Company disputes that (i) a default has occurred as contemplated in Section 9.2 “Termination by University”, or that a default has not been cured, or (ii) Company wishes to dispute termination of this Agreement resulting from a failed negotiation of a new Performance Milestone as contemplated under Section 5.2 “Renegotiation of Performance Milestones”, then Company may provide University with a written dispute notice (“Dispute Notice”) prior to expiration of the [***]-day cure period referenced in Section 9.2, stating the basis of Company’s disagreement with respect to such default or cure, or (b) if there is a dispute as provided under Sections 3.3 or 7.2, then either Party may provide the other with a Dispute Notice. If Company disputes that a default has occurred as contemplated in Section 9.3 “Events of Default”, then Company may provide University with a Dispute Notice within [***] days of University sending the notice of termination referenced in Section 9.3. Upon receipt of a Dispute Notice, University’s right to terminate this Agreement will be suspended and all rights under this Agreement will continue unaffected provided the dispute resolution process in this Section 13.4 “Escalation; Dispute Resolution” is being exercised. Any dispute will first be escalated to Company’s Chief Executive Officer or to a representative from Company’s Board of Directors, and to University’s Vice President for Innovation Strategy, representatives of which will be instructed to work in good faith to attempt to reach a mutually acceptable resolution of the dispute that would avoid termination of this Agreement. If the representatives are unable to reach such resolution of the dispute within [***] days of delivery of the Dispute Notice, an independent, neutral mediator acceptable to both Parties (acting reasonably) will be appointed. The Parties will submit their dispute to mediation according to such parameters as they may mutually agree in writing. The Parties agree to discuss their differences in good faith and to attempt in good faith, with facilitation by the mediator, to reach an amicable resolution of the dispute within [***] days after the mediator’s appointment. If the Parties are not able to agree on resolution of the dispute within such period, or within [***] days of the Dispute Notice, whichever is earlier, including agreeing on a new Performance Milestone pursuant to Section 5.2 “Renegotiation of Performance Milestones” if that is the subject of the dispute, then the dispute resolution process of this Section 13.4 “Escalation; Dispute Resolution” will be complete and either Party may pursue any other action that is legally available to it. Notwithstanding the foregoing, no dispute affecting the rights or property of HHMI shall be subject to arbitration.

Company hereby submits to the jurisdiction of that court and waives any objections it may have to that court asserting jurisdiction over Company or its assets and property.

13.21 Entire Agreement. Company has evaluated the innovations and Licensed Patents under a Confidentiality Agreement (“CDA”) with University (UW reference number 43597A), dated September 14, 2018. In addition, Company and University executed an exclusive option agreement (“Option”) for certain Licensed Patents, with University reference UW reference number 43729A, dated November 29, 2018. This Agreement (including all attachments, exhibits, and amendments) is the final and complete understanding between the Parties concerning licensing the Licensed Rights.

However, the obligations of nonuse and nondisclosure for Confidential Information disclosed under the CDA and Option will survive according to the terms of those agreements. Confidential Information disclosed under this Agreement will be governed by the terms of this Agreement. This Agreement may not be modified in any manner, except by written agreement signed by an authorized representative of both Parties.

A3.2.1 Third Party Royalties. If Company or its Sublicensees are required to pay royalties to a Third Party based on Company’s or such Sublicensee’s manufacture, use, offer for sale, sale or import of Licensed Product subject to one or more patents of such Third Party that create a total royalty burden for the Licensed Product of greater than [***] percent ([***]%) (such figure including the above running royalty to University), then the royalty Company pays to University may be reduced by the lesser of (i) [***] percent ([***]%) of the royalty otherwise due to the University absent of a Third Party royalty reduction, (ii) [***] percent ([***]%) of the royalty actually paid to the Third Party, or (iii) the percent Company may reduce such Third Party royalty by based on a royalty stacking provision for the same product. To qualify for this reduction the Third Party patent must be required for the manufacture, use, offer for sale, sale or import of the Licensed Product

In addition, Company agrees to issue additional Shares to University sufficient to cause the University to own in aggregate [***] percent ([***]%) of Company’s Fully-Diluted Shares through such time as the Company has raised Qualified Financing; provided, however, that if Company closes an equity financing that would result in its cumulative equity capital raised being in excess of the Qualified Offering Proceeds, any such excess capital (and resulting dilution) will be ignored and the number of additional Shares to be issued to University will be calculated assuming Company had raised only such amount of equity capital as would result in its cumulative equity capital raised since incorporation being equal to the Qualified Offering Proceeds. Any such additional Shares will be issued as of or immediately after such closing.

A3.5.1 Participation Rights. If the Company proposes to sell any equity securities or securities that are convertible into equity securities of the Company (collectively, “Equity Securities”), then the University and/or its Assignee (as defined below) will have the right to purchase up to [***] percent ([***]%) of the securities issued in each offering on the same terms and conditions as are offered to the other purchasers in each such financing. Company shall provide ten business days advanced written notice of each such financing, including reasonable detail regarding the terms and purchasers in the financing. If all Equity Securities that the University and/or its Assignee are entitled to purchase pursuant to this Subsection A3.5.1 are not elected to be purchased by the University and/or its Assignee during such ten business day period, the Company may offer the remaining unsubscribed portion of such Equity Securities to any person or persons at a price not less than that, and upon terms no more favorable to the offeree than those, specified in such written notice. The term “Assignee” means (a) any entity to which the University’s participation rights under this section have been assigned either by the University or another entity, or (b) any entity that is controlled by the University. Notwithstanding the foregoing, the foregoing participation rights shall not apply to the following: (i) the issuance or sale of Shares or options therefor, to employees, directors, consultants and other service providers for the primary purpose of soliciting or retaining their services pursuant to plans or agreements approved by the Company’s Board of Directors (the “Board”); (ii) the issuance of securities pursuant to the conversion or exercise of convertible or exercisable securities that are outstanding as of the date hereof; (iii) the issuance of securities in connection with a bona fide business acquisition by the Company, whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise, approved by the Board; (iv) the issuance of stock, warrants or other securities or rights pursuant to any equipment leasing arrangement or debt financing arrangement, which arrangement is approved by the Board and is primarily for non-equity financing purposes; (v) the issuance of stock, warrants or other securities or rights to persons or entities with which the Company has business relationships, provided such issuances are approved by the Board and are primarily for non-equity financing purposes; (vi) the issuance of Equity Securities that are specifically deemed (in a written instrument) not to be subject to the participation rights set forth in this Subsection A3.5.1 by the University and/or its Assignee; or (vii) the issuance of any other Equity Securities that are excluded from any right of first offer or participation right granted by the Company to any of its investors and set forth in an “Investors’ Rights Agreement” or any similar agreement at any time then-outstanding. In addition to the foregoing, this participation right shall not be applicable with respect to any Assignee in any subsequent offering of Equity Securities if (x) at the time of such offering, Assignee is not an “accredited investor,” as that term is then defined in Rule 501(a) of the Securities Act of 1933, as amended, and (y) such offering of Equity Securities is otherwise being offered only to accredited investors. This paragraph shall survive the termination of this Agreement.

A3.6 Sublicense Consideration. Within [***] days of the end of each calendar quarter during the term of this Agreement, Company will pay to University [***] percent ([***]%) of any Sublicense Consideration received by Company during such calendar quarter unless reduced by achievement of milestones by Company or its Sublicensees prior to execution of the particular Sublicense in accordance with the schedule below; provided that if the nature of the sublicense is a co-development agreement where Company remains involved in the funding and/or conduct of the development, then the percentage of Sublicense Consideration will be based on status of the molecular entity (agonist in A2.1, [***] molecule in A2.2, or antagonist in A2.3) at the time the Sublicense Consideration payment is received by Company. Determination of the relevant Performance Milestone having been achieved for the purposes of determining the Sublicense Consideration percentage shall be based on the milestones achieved by the most advanced molecular entity under development by Company that is the same type of molecular entity as the Licensed Product then in development for which Sublicense Consideration was received. A reduction of the percentage of Sublicense Consideration payable to University under this Agreement will be negotiated in good faith between the Parties where, in addition to the Sublicense of any rights granted to Company hereunder, Company or its Sublicensee also grants a Sublicensee a license under a Third Party’s intellectual property rights that are infringed by Licensed Product(s), and only to the extent that the total aggregate consideration for such combined license is treated as Sublicense Consideration.

The Acquisition Fee otherwise due under this Section A3.7 will be reduced and offset by the amount of consideration attributable to University’s Shares under Section A3.5 “Equity” above. For this purpose, the consideration attributable to the Shares will be deemed to include all amounts paid at closing, placed in escrow, subject to earnout payments, or otherwise contemplated by the agreement relating to such Acquisition, to the extent such amounts are actually received by University. The Company will act in good faith and will not intentionally seek to avoid payment of or reduce the Acquisition Fee by raising capital or achieving other Performance Milestones specifically for that purpose.

A3.8 Patent Expense Payment. Company will pay, or reimburse University for paying, all Patent Expenses incurred prior to, on or after the Effective Date, within [***] days of its receipt of University’s invoice for such Patent Expenses. University reserves the right to request advance payments for certain Patent Expenses, at University’s discretion.

Exhibit C

STOCK SUBSCRIPTION AGREEMENT

STOCK SUBSCRIPTION AGREEMENT, dated the date indicated below on the signature page hereof, by and between the Company and the University. If and when accepted by the Company, this Stock Subscription Agreement, when executed below, shall constitute a subscription for that number of shares of the Securities indicated on the attached Appendix A. All capitalized terms are defined on Appendix A.

INTENDING TO BE LEGALLY BOUND, and in consideration of the mutual representations, warranties, covenants and agreements contained herein, Company and University hereby agree as follows:

1. Representations and Warranties of the University. The University hereby represents and warrants to the Company as of the date of this Agreement as follows:

1.1 The University: (a) is an Accredited Investor as that term is defined in 17 CFR § 230.501(a); (b) has been furnished with all information deemed necessary by the University to evaluate the merits and risks of the Securities; (c) has had the opportunity to ask questions and receive answers concerning the Company and the Securities; and (d) has been given the opportunity to obtain any additional information necessary to verify the accuracy of any information obtained concerning the Company.

1.2 Ability to Bear Risk. The University is in a financial position to hold the Securities and is able to bear the economic risk and withstand a complete loss of the investment in the Securities.

1.3 Risk Factors. The University recognizes that the Securities as an investment involve an extremely high degree of risk. There can be no assurance that the Company will be able to meet its projected goals and the Company may need significant additional capital to be successful, which capital may not be readily available or available upon terms that are not substantially dilutive to the University. If provided, the University has reviewed the risk factors description provided by the Company.

1.4. Sophistication. The University is a sophisticated investor, is able to fend for itself in the transactions contemplated by this Agreement, and has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the prospective investment in the Securities.

1.5. Suitability. The investment in the Securities is suitable for the University based upon its investment objectives and financial needs, and the University has adequate net worth and means for providing for its current financial needs and contingencies and has no need for liquidity of investment with respect to the Securities.

1.6. Overall Commitment to Illiquid Investments. The University’s overall commitment to investments which are illiquid or not readily marketable is not disproportionate to its net worth, and investment in the Securities will not cause such overall commitment to become excessive.

CONFIDENTIAL

1.7. Restricted Securities. The University realizes that (i) none of the Securities have been registered under the Securities Act of 1933, as amended (the “Act”), (ii) the Securities are characterized under the Act as “restricted securities” and, therefore, cannot be sold or transferred unless they are subsequently registered under the Act or an exemption from such registration is available and (iii) there is presently no public market for the Securities and the University may not be able to liquidate his investment in the event of an emergency or pledge the Securities as collateral security for loans. In this connection, the University represents that it is familiar with Rule 144 promulgated under the Act, and understands the resale limitations imposed thereby and by the Act.

1.8. Exemption Reliance. The University has been advised that the Securities are not being registered under the Act or the applicable state securities laws but are being offered and sold pursuant to exemptions from such laws. The University understands that the Company’s reliance on such exemptions is predicated in part upon the truth and accuracy of the University’s representations in this Agreement.
