1.3 “Confidential Information” of a party shall mean, subject to the exceptions specified below, all information disclosed by such party (the “disclosing party”) to the other party (the “receiving party”), whether in oral, written, graphic or electronic form. Notwithstanding the foregoing, the Assets shall be deemed the Confidential Information of Purchaser (i.e., Purchaser shall be considered the disclosing party and Seller shall be considered the receiving party with respect thereto), and, except as otherwise provided in Article 5 hereof, the contents of this Agreement shall be considered the Confidential Information of both parties.

Such amounts shall be determined in accordance with U.S. generally applicable accounting principles, consistently applied, and may include using accrual accounting where applicable. In no event will any particular amount identified above be deducted more than once in calculating Net Sales (i.e., no “double counting” of reductions).

2. Purchase And Sale Of Assets

2.1 Purchase and Sale of Assets. Subject to the terms and conditions of this Agreement, including, without limitation, payment in accordance with Article 3, and effective as of the Effective Date, Seller hereby sells, transfers, conveys, assigns and delivers to Purchaser all of Seller’s right, title and interest in and to the Assets, free and clear of any liens, claims, liabilities, options, pledges, mortgages, security interests, restrictions and encumbrances of any kind, whether accrued, absolute, contingent or otherwise. Without derogating from the foregoing, and for the avoidance of doubt, it is hereby clarified that upon such sale and assignment, Purchaser shall have the absolute right, at Purchaser’s sole cost and expense: (a) to seek to have any existing intellectual property rights in the Assets vested and/or registered in its name or as directed by it and to protect and enhance its ownership of the Assets by obtaining further and/or new intellectual property rights in the Assets anywhere in the world; and (b) to develop and commercialize the Assets and/or products which utilize or incorporate the Assets, including the rights for Purchaser, its Affiliates and/or third parties licensed or otherwise authorized by Purchaser or its Affiliates, to research, develop, promote, market, sell, distribute, manufacture (or have manufactured), register, import, export or use the Assets and/or products which utilize or incorporate the Assets.

2.2 Further Actions.

(a) From and after the Effective Date, Seller shall, without further consideration, execute and deliver such documents and other instruments of transfer, and take such other actions, as Purchaser determines in good faith to be necessary or appropriate in order to put Purchaser in possession of, and to vest in Purchaser, good, valid and unencumbered title to the Assets in accordance with this Agreement and to effect, record, evidence and perfect the assignment of the Assets to Purchaser. Without limiting the generality of the foregoing, Seller shall execute and deliver to Purchaser such documents and other instruments as Purchaser determines in good faith to be necessary or appropriate in order to transfer to Purchaser, and to put Purchaser in possession of and to vest in Purchaser, good, valid and unencumbered title to, the Patent Rights, and to effect, record, evidence and perfect Purchaser’s ownership of the Patent Rights, including patent assignments that Purchaser may reasonably require.

(b) Seller hereby constitutes and appoints Purchaser, and any successor or assign of Purchaser, its true and lawful attorney-in-fact with full power of substitution for it and in its name, place and stead or otherwise on behalf of it, its successors and assigns, and for the benefit of Purchaser and any successor or assign of Purchaser, (i) to execute in the name of Seller and its successors and assigns, instruments of conveyance with respect to the Assets, (ii) from time to time to institute and prosecute in the name of Purchaser any and all proceedings at law, in equity or otherwise which Purchaser or any successor and assign of Purchaser may deem proper in order to collect, assert or enforce any claims, rights or titles of any kind in and to the Assets, (iii) to defend and compromise any and all actions, suits or proceedings in respect of any of the Assets, and (iv) to do any and all such acts and things in furtherance of the sale, transfer, conveyance, assignment and delivery of the Assets as Purchaser or any successor or assign of Purchaser shall deem advisable. Seller declares that the foregoing appointment and power of attorney are coupled with an interest and are and shall be irrevocable and perpetual.

(c) From and after the Effective Date, Seller shall execute, verify, and deliver (and/or cause its employees to execute, verify and deliver) such documents, perform such other acts, and provide such other assistance as Purchaser may reasonably request in order to apply for, prosecute, maintain, defend and enforce the Patent Rights in any jurisdiction, provided that Purchaser shall compensate Seller for the provision of such assistance (other than for mere execution, verification and delivery of documents) at a reasonable hourly rate to be mutually agreed by the parties for the time actually spent by Seller at Purchaser’s request on providing such assistance.

3. Payments

3.1 Purchase Price. In full consideration of the assignments and other rights conveyed to or conferred upon Purchaser under Article 2 hereof, Purchaser shall:

(a) issue to Seller a convertible promissory note in the principal amount of five hundred thousand dollars ($500,000) on the terms set forth in the form of convertible promissory note attached hereto as Exhibit B (the “Convertible Note”);

(b) pay to Seller contingent payments (the “Milestone Payments”) for the achievement of the following milestone events (the “Milestone Events”) by Purchaser or its Affiliate or licensee in the amounts set forth below, which shall be payable [***] days after the achievement of the applicable Milestone Event:

(i) $[***];

(ii) $[***];

(iii) $[***];

(iv) $[***];

(v) $[***];

(vi) $[***];

(vii) $[***];

(viii) $[***]; and

(ix) $[***].

(c) pay to Seller royalties on Products sold by or on behalf of Purchaser or its Affiliates or licensees (the “Royalties”) on a Product-by-Product and country-by-country basis during the period from the first commercial sale of a Product in a given country through the date of expiration of the last-to-expire of the Patent Rights that include a [***] (the “Royalty Period”). Royalties due each calendar year during the Royalty Period shall be calculated by multiplying the incremental Net Sales of Products for such year against the applicable royalty rate identified below, subject to any applicable reductions provided for in Section 3.4, with each royalty rate referred to below applying only to that increment of Net Sales that falls within the incremental sales bracket for such royalty rate.


Annual aggregate Net Sales of Products		Royalty Rate

Less than or equal to $[***]		[***]%

Greater than $[*] and less than or equal to $[*]		[***]%

Greater than $[***]		[***]%

To illustrate, if, for example, aggregate annual worldwide Net Sales of Products upon which royalties are due and payable as provided in this Section 3.1(c) were $[***] during any year of the Royalty Period, then absent any reductions pursuant to Section 3.4, the royalties due would be calculated as follows: ([***] x $[***]) + ([***] x $[***]).

3.2 Royalty and Milestone Payments. Royalties due under Section 3.1(c) shall be paid no later than [***] days following the end of each calendar quarter during the Royalty Period and accompanied by a reasonably detailed written accounting of Net Sales for the applicable calendar quarter in sufficient detail to permit confirmation of the accuracy of the Royalties paid. The Milestone Payments and Royalties shall be payable in U.S. dollars by wire transfer to a bank and account designated in writing by Seller, unless otherwise specified in writing by Seller. Except as otherwise provided in Section 3.1(b)(v), each of the Milestone Payments shall be payable one time only upon the first occurrence of the applicable Milestone Event, regardless of the number of Products developed or the indications for which any Product is developed. When conversion of payments from any foreign currency is required in connection with the payment of any Royalties, such conversion shall be made using the exchange rate used by Purchaser or, as applicable, its Affiliate or licensee, in its accounting system for the calendar quarter to which such payments relate. Purchaser shall be solely responsible for any payments due or payable to any third party in connection with the development or commercialization of any Product.

[***] = CERTAIN CONFIDENTIAL INFORMATION OMITTED

3.3 Royalty Termination. After the payment of all Milestone Payments and Royalties due and payable through the end of the Royalty Period, Purchaser shall have no further obligation to make any payments to Seller under Section 3.1(b) or (c).

3.4 Royalty Reduction. If Purchaser or any of its Affiliates or licensees is obligated or finds it reasonably necessary to pay consideration to any third party (other than an Affiliate) that holds a patent that is in the reasonable judgment of Purchaser or its Affiliate or licensee and its counsel would [***], and if the [***] to Seller and such third party(ies) [***] percent ([***]%), then the royalty percentage to be paid to Seller by Purchaser set forth above shall be reduced by the percentage calculated by the following formula: [***], in which A is the [***] and B is [***] on the Product. For example, if, after [***] $[***], the [***] due to Seller and one non-Affiliate third party is [***] percent ([***]%), the reduction would be equal to [***], or [***]% and, the royalty percentages owed to Seller as set forth in Section 3.1(c) above would be reduced to [***] percent ([***]%). However, in no event shall the royalty amount payable to Seller for any [***] be reduced below [***] percent ([***]%) of the royalty that would otherwise payable as set forth in Section 3.1(c), without reduction pursuant to this Section 3.4.

3.5 Representations and Warranties. In connection with Section 3.1(a), Seller represents and warrants to Purchaser as follows:

(a) Purchase Entirely for Own Account. The applicable equity securities of Purchaser to be acquired by Seller will be acquired for investment for Seller’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and Seller has no present intention of selling, granting any participation in, or otherwise distributing the same. Seller does not presently have any contract, undertaking, agreement or arrangement with any third party to sell, transfer or grant participations to such third party, with respect to any of the applicable equity securities of Purchaser.

(b) Disclosure of Information. Seller has had an opportunity to discuss Purchaser’s business, management, financial affairs and the terms and conditions of the offering of the applicable equity securities of Purchaser with Purchaser’s management.

(c) Restricted Securities. Seller understands that the applicable equity securities of Purchaser have not been, and will not be, registered under the Securities Act of 1933, as amended, by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of Seller’s representations as expressed herein. Seller understands that the applicable equity securities of Purchaser are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, Seller must hold such equity securities indefinitely unless they are registered with the Securities and Exchange Commission and qualified by state authorities, or an exemption from such registration and qualification requirements is available. Seller acknowledges that Purchaser has no obligation to register or qualify the applicable equity securities of Purchaser, or any securities into which such equity securities may be converted, for resale except as set forth in the Convertible Note. Seller further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the applicable equity securities of Purchaser, and on requirements relating to Purchaser which are outside of the Seller’s control, and which Purchaser is under no obligation and may not be able to satisfy.

(d) No Public Market. Seller understands that no public market now exists for the applicable equity securities of Purchaser, and that Purchaser has made no assurances that a public market will ever exist for such securities.

(e) Accredited Investor. Seller is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities Act.

(f) Legends. Seller understands that the stock certificates for the applicable equity securities of Purchaser and any securities issued in respect of or exchange for such equity securities, may bear one or all of the following legends:

(i) “THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE

[***] = CERTAIN CONFIDENTIAL INFORMATION OMITTED

REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933, AS AMENDED”.

(ii) Any legend set forth in, or required by, applicable financing agreements entered into in connection with the issuance of the equity securities.

(iii) Any legend required by the securities laws of any state to the extent such laws are applicable to such equity securities represented by the certificate so legended.

3.6 Audit Rights. Purchaser shall keep, and shall cause its Affiliates and licensees, as applicable, to keep records in sufficient detail with respect to the Royalties. Upon written request from Seller, Purchaser shall provide Seller with written certification from Purchaser’s auditors concerning the accuracy of the calculation of Royalties and corresponding Royalties payments for each calendar quarter (or portion thereof, as applicable) within the Royalty Period. In the event the audit indicates any underpayment for a given calendar quarter (or portion thereof, as applicable) within the Royalty Period by Purchaser, Purchaser shall promptly pay Seller for the additional Royalties owed by Purchaser for such calendar quarter (or portion thereof, as applicable). Purchaser shall pay interest at [***] regarding any underpayment from the time period commencing when the payment should have been made until the date of payment.

3.7 Taxes. Purchaser shall be responsible for the payment of any sales, use, transfer or similar taxes arising out of or in connection with the transactions contemplated by Article 2. Purchaser will make all payments to Seller under this Agreement without deduction or withholding for any taxes except to the extent that any such deduction or withholding is required by applicable law in effect at the time of payment. If any taxes are required to be withheld by Purchaser, Purchaser shall (a) deduct such taxes from the payment to Seller, (b) increase the sum payable to Seller by the amount necessary to yield to Seller an amount equal to the sum it would have received had no withholdings or deductions been made (c) timely pay the taxes to the proper taxing authority, and (d) send proof of payment to Seller and certify its receipt by the taxing authority promptly following such payment. The parties agree to cooperate in good faith to obtain the benefit of any tax treaty that may be applicable to the payments made or to be made under this Agreement. If Seller or any of its members (only in their capacity as members of Seller) is able to obtain credit for any taxes for which an additional payment is made by Purchaser under this Section (“Creditable Taxes”) against any tax liability otherwise payable by Seller or any of its members (only in their capacity as members of Seller), Seller shall reimburse to Purchaser an amount equivalent to the Creditable Taxes. Seller shall provide Purchaser with evidence as Purchaser may reasonably request to review the amount of any Creditable Taxes.

4. Representations And Warranties

4.1 Mutual Representations and Warranties. Each party represents and warrants to the other party that, as of the Effective Date: (a) the execution, delivery and performance of this Agreement by such party have been duly authorized by all necessary action on the part of such party; and (b) this Agreement constitutes the legal, valid and binding obligation of such party, enforceable against such party in accordance with its terms.

EXCEPT FOR PAYMENTS UNDER ARTICLE 3 OR LIABILITY FOR BREACH OF ARTICLE 5, NEITHER PARTY SHALL BE ENTITLED TO RECOVER FROM THE OTHER PARTY ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES IN CONNECTION WITH THIS AGREEMENT; provided, however, that this Section 4.4 shall not be construed to limit either party’s indemnification obligations under Article 6.

5.1 Confidentiality. The receiving party hereby agrees to keep confidential and not to publish or otherwise disclose or use for any purpose any Confidential Information of the disclosing party.

The Holder also may exercise from time to time any rights and remedies available to it by law.

4. Conversion.

(a) Mandatory Conversion. Subject to and in compliance with the provisions of this Section 4, at any time prior to the Maturity Date, upon the Company’s receiving gross proceeds of at least $10,000,000.00 (not including the aggregate principal amount of, and accrued interest on, the Note to be converted) in an offering or series of related offerings from the bona fide sale of Series A Preferred Stock or such other class of shares as are issued by the Company (a “Qualified Equity Financing”), the entire outstanding Principal Amount of this Note and all accrued and unpaid interest thereon shall automatically convert into shares of the Company’s capital stock with equivalent rights and preferences as the shares issued in such Qualified Equity Financing (such shares to be issued upon such conversion hereof, the “Qualified Equity Financing Shares”) at a conversion price equal to the lowest per share purchase price paid for the shares offered in the Qualified Equity Financing.

(b) Conversion Procedure. Before the Holder shall be entitled to convert this Note into Qualified Equity Financing Shares pursuant to Section 4(a) above, the Holder shall surrender this Note, duly endorsed, at the office of the Company. The conversion shall be deemed to have been made immediately prior to the close of business on the date of the consummation of the Qualified Equity Financing. Thereupon, the Company shall promptly issue and deliver to the Holder a certificate or certificates for the number of Qualified Equity Financing Shares to which the Holder is entitled.

(c) Note No Longer Outstanding. Upon conversion of this Note, this Note shall no longer be deemed to be outstanding and all rights of the Holder as a holder of this Note shall cease.

(d) Fractional Shares. No fractional Qualified Equity Financing Shares shall be issued upon conversion of this Note. The Company shall, in lieu of issuing any fractional shares, pay the Holder cash equal to the product of such fraction multiplied by the applicable conversion price on the date of conversion.

(e) Execution of Agreements Upon Conversion. If this Note converts upon a Qualified Equity Financing pursuant to Section 4(a) above, then in connection therewith, the Holder and the Company will, if requested by either the Company or Holder, execute and deliver to each other such agreements (including, without limitation, a purchase agreement, investor rights agreement, right of first refusal/co-sale agreement and voting agreement (the “Financing Agreements”)) as are executed and delivered by other investors in such financing.

5. Change of Control.

The Company shall provide written notice to the Holder of a Change of Control at least 15 days in advance of the consummation thereof. A “Change of Control” means (a) any merger with another company or an acquisition of the Company, whether by recapitalization, consolidation, sale of outstanding equity securities or otherwise, as a result of which the existing equity holders of the Company prior to
