          (d) “Patent Rights” means invention disclosures, patent applications, and patents that the Medical School has the authority to license and are not obligated to other parties (e.g., by sponsored research agreement, material transfer agreements,) for license by the Medical School within the Field, but specifically excludes inventions or other technology developed by laboratories of Howard Hughes Medical Institute investigators, whether resulting in invention disclosures, patent applications, patents or other tangible media.

     1.2. Disclosure. After the internal disclosure is accepted by Medical School according to Medical School policy, the Medical School shall promptly disclose to Company in reasonable detail in writing Patent Rights in the Field that are conceived or reduced to practice by the Medical School during the term of this Agreement.

     1.3. MEDICAL SCHOOL MAKES NO WARRANTIES CONCERNING THE PATENT RIGHTS, INCLUDING WITHOUT LIMITATION ANY EXPRESS OR IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Specifically, Medical School makes no warranty or representation (a) regarding the validity, scope, or patentability of any Patent Rights, (b) that the exploitation of the Patent Rights will not infringe any patents or other intellectual property rights of a third party, and (c) that any third party is not currently infringing or will not infringe the Patent Rights.

2. Consideration for Disclosure Right. In consideration of the rights granted Company under this Agreement, Company shall pay the following to Medical School as of the Effective Date One Million One Hundred Thousand US Dollars ($1,100,000) according to the following schedule.

     2.1. Eight Hundred Thousand US Dollars ($800,000) within thirty (30) days of the Effective Date, payable in cash or that number of shares of Common Stock of Company having an aggregate valuation equal to Eight Hundred Thousand US dollars ($800,000) according to the Company valuation at the Initial Financing. In connection with the issuance of stock pursuant to this Section 2.1, Medical School agrees to become a party to other agreements of Company to the same extent (except any limitations relating to the Medical School’s status as an agency of the Commonwealth of Massachusetts, e.g., prohibition on indemnification) as holders of more than five percent (5%) of the Common Stock of Company (such as, voting agreement and stock restriction agreement). University acknowledges that all certificates representing the shares described in this Section 2.1 may bear customary legends requiring compliance with the Securities Act of 1933 and related state securities laws upon any transfer of such shares. Company shall use commercially reasonable efforts to register the stock issued to Medical School pursuant to this Section 2.1 as soon as possible, subject to customary terms in connection with such transaction.

     3. Option to License Patent Rights.

     3.1. Within sixty (60) days after disclosure pursuant to Section 1.2 (the “Option Period”), Company may choose to negotiate a license for the Patent Rights after Company pays the Medical School a nonrefundable “Option Fee” of Twenty-Five Thousand Dollars ($25,000) within the Option Period. After timely receipt of the Option Fee, Medical School grants Company a first option to negotiate a worldwide, royalty-bearing, exclusive license under its rights in the Patent Rights within the Field (the “Option Right”).

     3.2. If Company elects not to exercise the Option Right, or fails to exercise the Option Right during the Option Period, Medical School may license its rights under the Patent Rights to any third party without recourse by or obligation to Company.

     3.3. If Company does elect to exercise the Option Right, Medical School and Company shall negotiate in good faith a license agreement containing commercially reasonable terms in the form of Medical School’s then current standard license agreement. If Medical School and Company do not reach agreement within one hundred twenty (120) days after Company exercises the Option Right (the “Negotiation Period”), Medical School may offer its rights in the Patent Rights to any third parties without recourse by or obligation to Company. However, if the parties fail to reach an agreement within the Negotiation Period, the following terms apply:

          a. Within five (5) business days after expiration of the Negotiation Period, Company may elect to have the terms of the license determined by arbitration by delivering written notice of that election to Medical School. If Company elects arbitration, the arbitration shall be conducted in Boston, Massachusetts, by one (1) independent arbitrator who is experienced in licensing biotechnology intellectual property. The arbitrator shall be chosen by mutual consent of the parties within thirty (30) days after Company elects arbitration. Company shall pay the first Ten Thousand Dollars ($10,000) of the expenses of the arbitration, and thereafter the parties shall share the expenses equally. Unless Company rejects the arbitrator’s decision or fails to enter into the license agreement within ten (10) days after the arbitrator’s decision, each party is responsible for its own legal expenses in association with the arbitration. The arbitration shall be in a format in which the arbitrator shall rule that either Company’s or Medical School’s proposed terms are the final terms. The arbitrator shall issue its ruling to the parties within sixty (60) days of being selected. Once the terms have been established by the arbitrator and delivered in writing to Company, Company has ten (10) days to enter into the license agreement on those terms or to reject those terms. If Company rejects those terms or fails to enter into the license agreement within ten (10) days after the arbitrator’s decision, (a) Medical School thereafter is free to license its rights under the Patent Rights to any third party without further notice to Company, and (b) Company shall reimburse Medical School for its out-of-pocket arbitration expenses.

          b. If Company does not elect arbitration pursuant to Subsection 3.3(a), Medical School is free to license its rights under the Patent Rights to any third party.

4. Patent Rights. Medical School is responsible at its expense and in its sole discretion for the preparation, filing, prosecution, and maintenance of the optioned Patent Rights.

5. Information Exchange.

The notice shall summarize the Confidential Information and reference the time and place of disclosure.

     5.3. Obligations. For five (5) years after disclosure of any portion of Confidential Information, the Receiving Party shall (a) maintain Confidential Information in confidence, except that the Receiving Party may disclose or permit the disclosure of any Confidential Information to its directors, officers, employees, consultants, and advisors who are obligated to maintain the confidential nature of Confidential Information and who need to know Confidential Information for the purposes of this Agreement; (b) use Confidential Information solely for the purposes of this Agreement; and (c) allow its trustees or directors, officers, employees, consultants, and advisors to reproduce the Confidential Information only to the extent necessary for the purposes of this Agreement, with all reproductions being Confidential Information.

     6.6. Force Majeure. Neither party is responsible for delays resulting from causes beyond its reasonable control, including without limitation, fire, explosion, flood, war, strike, terrorism, or riot, provided that the nonperforming party uses commercially reasonable efforts to avoid or remove those causes of nonperformance and continues performance under this Agreement with reasonable dispatch whenever the causes are removed.

7. Miscellaneous.

     7.1. Publicity Restrictions. Neither party may use the name of the other or any of its trustees, officers, faculty, students, employees, or agents, or any adaptation of those names, or any terms of this Agreement in any promotional material or other public announcement or disclosure without the prior written consent of the other party. The foregoing notwithstanding, (a) Company or CytRx Corporation may disclose such information without the consent of Medical School in any prospectus, offering memorandum, or other document or filing required by applicable securities laws or other applicable law or regulation, provided that Company or CytRx Corporation shall provide Medical School at least ten (10) days (or a shorter period in order to enable Company to make a timely announcement to fulfill applicable securities laws or other applicable law or regulation, while affording Medical School the maximum feasible time to review the announcement) prior written notice of the proposed text for the purpose of giving Medical School the opportunity to comment on the text, and (b) Medical School may disclose the existence of the agreement (but not its terms) according to its customary practice of disclosing its research sponsors and collaborators.

If the Internal Revenue Service determines, or if counsel to Medical School reasonably determines, that any term of this Agreement jeopardizes the tax-exempt status of Medical School or the bonds used to finance Medical School facilities, the relevant term is invalid and the parties shall modify the term pursuant to Section 7.8.

     7.4. Assignment. This Agreement may not be assigned by either party without the prior written consent of the other party, including without limitation, in connection with a merger, consolidation, or sale of all or substantially all of its assets or that portion of its business (including any subsidiary) to which this Agreement relates
