14.5Dispute Resolution.

(a)Except for any “Excluded Claim” (defined in Section 14.5(g) below), the Parties shall negotiate in good faith and use reasonable efforts to settle any dispute, controversy or claim arising from or related to this Agreement, or the breach thereof, as follows. Any Party shall give the other Party written notice of any dispute, controversy or claim not resolved in the normal course of business.  Within fifteen (15) Business Days from the date of delivery of such notice, the receiving Party shall submit to the other Party a written response.  The notice and response shall include (a) a statement of that Party’s position and a summary of arguments supporting that position, and (b) the name and title of the executive who will represent that Party and of any other person who will accompany the executive.  Within thirty (30) Business Days from the date of delivery of the initial notice, the executives of both Parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to attempt to resolve the dispute, controversy or claim. These executives shall have the authority to settle the dispute and shall be at a higher level of management than the persons with direct responsibility for

25

 

---

 

administration of this Agreement. All negotiations pursuant to this paragraph are confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.  

(b)If the Parties do not fully settle within thirty (30) Calendar Days of such meeting, and a Party wishes to pursue the matter, each such dispute, controversy or claim that is not an Excluded Claim shall be finally resolved by binding arbitration in accordance with the Commercial Arbitration Rules and Supplementary Procedures for Large Complex Disputes of the American Arbitration Association (“AAA”), and judgment on the arbitration award may be entered in any court having jurisdiction thereof.

(c)The arbitration shall be conducted by a panel of three (3) persons experienced in the pharmaceutical business (provided that such arbitrators are not required to be selected from AAA’s list of arbitrators) as follows: (a) within ten (10) Business Days after initiation of arbitration, each Party shall select one (1) person to act as arbitrator, and (b) the two (2) Party-selected arbitrators shall select a third arbitrator within five (5) Business Days of their appointment. If the arbitrators selected by the Parties are unable or fail to agree upon the third arbitrator, the third arbitrator shall be appointed promptly by the AAA. The place of arbitration shall be Waco, Texas.

(d)Either Party may apply to the arbitrators for any applicable interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either Party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending the arbitration award. The arbitrators shall have no authority to award punitive or any other type of damages not measured by a Party’s compensatory damages. Each Party shall bear its own costs and expenses and attorneys’ fees and an equal share of the arbitrators’ and any administrative fees of arbitration.

(e)Except to the extent necessary to confirm an award, or as may be required by applicable law, rule or regulation, neither a Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would be barred by the applicable law or statute of limitations.

(f)The Parties agree that, in the event of a dispute over the nature or quality of performance under this Agreement, neither Party may terminate the Agreement until final resolution of the dispute through arbitration or other judicial determination. The Parties further agree that any payments made pursuant to this Agreement pending resolution of the dispute shall be refunded if an arbitrator or court determines that such payments are not due.

(g)As used in this Section 14.5, the term “Excluded Claim” shall mean a dispute, controversy or claim that concerns: (a) the validity or infringement of a patent, trademark or copyright; (b) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory; or (c) the need to seek preliminary or injunctive measures or other equitable relief (e.g., in the event of a potential or actual breach of the confidentiality and non-use provisions in Section

26

 

---

 

11). An Excluded Claim need not be resolved through the procedure described in Sections 14.5(a) – 14.5(f) and may be immediately brought in a court of competent jurisdiction.

14.6Severability. If any provision of this Agreement is determined by any court or administrative tribunal of competent jurisdiction in the Territory to be invalid or unenforceable under Applicable Laws, the Parties shall negotiate in good faith a replacement provision that is commercially equivalent, to the maximum extent permitted by the Applicable Laws, to such invalid or unenforceable provision. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of the other provisions of this Agreement.

14.7Governing Law. This Agreement shall be governed by and construed exclusively in accordance with the laws of State of Texas and, with respect to the Licensed Patents and related matters, the patent laws of the relevant patent granting jurisdiction (except that as between the Parties, inventorship shall be determined under United States patent law), without reference to any rules of conflicts of law or renvoi.

14.8Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, and all of which together shall constitute one and the same instrument. Each party acknowledges that an original signature or a copy thereof transmitted by facsimile or by pdf shall constitute an original signature for purposes of this Agreement.

14.9Headings. The subject headings of this Agreement are included for purposes of convenience only and shall not affect the construction or interpretation of any provision of this Agreement.

14.10Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

14.11Entire Agreement and Amendments. This Agreement, together with all Exhibits attached hereto, constitutes the entire agreement between the Parties, and supersedes all prior agreements, understandings and communications between the Parties, with respect to the subject matter hereof. No modification or amendment of this Agreement, including but not limited to this Section 14.11, shall be binding upon the Parties unless in writing and executed by the duly authorized representative of each of the Parties.

14.12Waivers. The failure by either Party hereto to assert any of its rights hereunder, including, but not limited to, the right to terminate this Agreement due to a breach or default by the other Party hereto, shall not be deemed to constitute a waiver by that Party of its right thereafter to enforce each and every provision of this Agreement in accordance with its terms.

Exhibit B

PLUS THERAPEUTICS, INC.
COMMON Stock Purchase Agreement

THIS COMMON STOCK PURCHASE AGREEMENT (the “Agreement”) is entered into effective as of [●], 2020, by and between Plus Therapeutics, Inc., a Delaware corporation (the “Company”), and NanoTx, Corp., a Delaware corporation (“Purchaser”) pursuant to that certain License Agreement between the Company and the Purchaser dated as of March 29, 2020 (the “License Agreement”).

1.Purchase of Shares

In partial consideration for Purchaser’s license to the Company of certain intellectual property under the License Agreement, the Company hereby issues to Purchaser, [●] shares (the “Shares”) of the Company’s Common Stock (the “Common Stock”), valued at the per share price of $[●] for an aggregate value of $300,000.

2.Securities Law Compliance

2.1Exemption from Registration

The sale of the Shares has not been registered under the Securities Act of 1933, as amended (the “1933 Act”), or registered or qualified under applicable state securities laws in reliance upon certain exemptions from such registration and qualification.  The Shares must be held indefinitely and may not be resold, transferred or otherwise disposed of without registration under the 1933 Act and registration or qualification under applicable state securities laws or an opinion of counsel, in form and substance reasonably satisfactory to the Company, that such registration and qualification is not required.  

2.2Representations and Warranties of the Purchaser

In connection with the purchase of the Shares, Purchaser represents to the Company as follows:

(a)This Agreement has been duly and validly authorized, executed and delivered on behalf of the Purchaser and is a valid and binding agreement of the Purchaser enforceable against the Purchaser in accordance with its terms, subject as to enforceability to general principles of equity and to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors' rights and remedies.

(b)Purchaser is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Shares.  Purchaser is purchasing the Shares for investment for Purchaser’s own account and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the 1933 Act or under any applicable state securities laws.  Purchaser does not have any present intention to transfer the Shares to any other party.  

1

---

 

Purchaser understands that the exemption from registration under the 1933 Act for the issuance of the Shares depends in part upon the bona fide nature of Purchaser’s investment intent as expressed in this Agreement.

(c)Purchaser understands that the Shares are “restricted securities” under federal and state securities laws and that, pursuant to these laws, Purchaser must hold the Shares indefinitely unless they are registered and qualified under such laws or an exemption from such registration and qualification is available.  Purchaser acknowledges that the Company has no obligation to register or qualify the Shares for resale.  Purchaser further acknowledges that, if an exemption from registration or qualification is available, it may be conditioned on certain requirements, including, but not limited to, the time and manner of sale, the holding period for the Shares and requirements relating to the Company, which are outside of Purchaser’s control and which the Company is under no obligation, and may not be able, to satisfy.

(d)Purchaser believes that an investment in the Shares is suitable for Purchaser based on Purchaser’s investment objectives and financial needs, and Purchaser is able to bear the economic risk of an investment in the Shares.  Purchaser has such knowledge and experience in financial and business matters as to make Purchaser capable of evaluating the risks of the prospective investment and to make an informed investment decision and is able to bear the economic risk of an investment in the Shares.  Purchaser has either (i) preexisting personal or business relationships with the Company or any of its officers, directors or controlling persons, or (ii) the capacity to protect Purchaser’s own interests in connection with the purchase of the Shares by virtue of the business or financial expertise of Purchaser or professional advisors to Purchaser who are unaffiliated with and who are not compensated by the Company or any of its affiliates, directly or indirectly.

(e)Purchaser realizes that an investment in the Shares is highly speculative and involves a high degree of risk, including, without limitation, the developmental stage of the Company, the need for additional capital, the ability of the Company to develop its products and services on a timely basis or at all, the market acceptance of the Company’s products or services, the rapid technological change and competition in the industry and the ability of the Company to assert and protect its intellectual property rights.

(f)The Purchaser understands that no U.S. federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Shares or the fairness or suitability of an investment in the Shares nor have such authorities passed upon or endorsed the merits of the offering of the Shares.

(g)The Purchaser represents and warrants to the Company that at no time prior to the date of this Agreement has the Purchaser, its agents, representatives or affiliates engaged in or effected, in any manner whatsoever, directly or indirectly, any (i) "short sale" (as such term is defined in Rule 200 of Regulation SHO of the 1933 Act or the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of the Common Stock or (ii) hedging transaction, which establishes a net short position with respect to the Common Stock.

▇.▇▇▇▇▇▇ Stand-Off Agreement

6.1Stand-Off. Purchaser agrees that Purchaser shall not transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale of, any Common Stock (or other securities) of the Company held by Purchaser (other than those included in the registration) during the one hundred eighty (180) day period following the date hereof (such period, the “Holding Period”) and during the ninety (90) day period following the effective date of any subsequent registration statement of the Company filed under the 1933 Act; provided that such restrictions with respect to any subsequent registration shall terminate one year from the date hereof.  The foregoing provisions shall not apply to the sale of any securities to an underwriter pursuant to an underwriting agreement and shall only be applicable to Purchaser if all then current officers and directors and greater than one percent (1%) stockholders of the Company enter into similar agreements.  The underwriters in connection with any public offering subject to this Section are intended third party beneficiaries and shall have the right to enforce the provisions hereof as though they were a party hereto.  The provisions hereof shall not apply to a registration relating solely to employee benefit plans on Form S‑8 or Rule 145 transactions on Form S‑4, or similar forms that may be promulgated in the future.  The Company may impose stop‑transfer instructions with respect to the securities subject to the provisions hereof until the end of the applicable periods.

6.2Exclusions. The provisions of Section 6.1 shall not apply to:

(a)transfers (A) by will, other testamentary document or intestate succession; or (B) by operation of law, such as pursuant to a qualified domestic order or as required by a divorce settlement (provided, however, that the transferee agrees to be bound in writing by the terms of this Agreement prior to such transfer, and such transfer shall not involve a disposition for value);

(b)the establishment of a trading plan pursuant to Rule 10b5-1 promulgated under the Exchange Act, provided that such plan does not provide for transfers during the Holding Period; or

(c)transfers by Purchaser to its shareholders as part of a distribution, or to any corporation, partnership or other entity that is its affiliate of Purchaser (provided, however, that the transferee agrees to be bound in writing by the terms of this Agreement prior to such transfer, and such transfer shall not involve a disposition for value).

7.Indemnification. The Company shall defend, protect, indemnify and hold harmless Purchaser and its officers, directors, employees and agents (the “Indemnitees”) to the fullest extent lawful from and against any and all actions, causes of action, suits, claims, losses (including losses from the diminution of value of any Shares), costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees

and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Company in this Agreement, or (b) any breach of any covenant, agreement or obligation of the Company contained in this Agreement. Notwithstanding anything in this Section 8, the Company will have no duty to indemnify the Indemnitees for Indemnified Liabilities in the aggregate in excess of $300,000.
