CAPRICOR THERAPEUTICS, INC.

The Company’s Board of Directors (the “Board”) has approved four stock option plans: (i) the 2006 Stock Option Plan, (ii) the 2012 Restated Equity Incentive Plan (which superseded the 2006 Stock Option Plan) (the “2012 Plan”), (iii) the 2012 Non-Employee Director Stock Option Plan (the “2012 Non-Employee Director Plan”), and (iv) the 2020 Equity Incentive Plan (the “2020 Plan”). In April 2021, the Board also approved the 2021 Equity Incentive Plan (the “2021 Plan”), however the 2021 Plan will not become effective unless and until it is approved by the shareholders of the Company. The Company is seeking stockholder approval for the 2021 Plan at its 2021 annual stockholders’ meeting.

Capricor and JHU entered into an Exclusive License Agreement (the “JHU Exosome License Agreement”) effective April 28, 2021 for its co-owned interest in certain intellectual property rights related to exosome-mRNA vaccines and therapeutics. The JHU Exosome License Agreement provides for the grant of an exclusive, world-wide, royalty-bearing license by JHU to Capricor, with the right to sublicense, in order to conduct research using the patent rights and know-how and to develop and commercialize products in the field using the patent rights and know-how.

Pursuant to the JHU Exosome License Agreement, JHU was paid an upfront license fee of $10,000 and Capricor has agreed to reimburse JHU for certain fees and costs incurred in connection with the prosecution of certain patent rights. Additionally, Capricor is required to meet certain development milestones for which a milestone payment fee shall be due and is obligated to pay low single-digit royalties on sales of royalty-bearing products as well as a double-digit percentage

of any non-royalty consideration received from any sublicenses. The above-mentioned royalties are subject to reduction in the event Capricor becomes obligated to pay royalties on one or more third party patents as a requirement to make or sell a licensed product. In addition, Capricor will, beginning with the third year of the JHU Exosome License Agreement, be obligated to pay JHU a minimum annual royalty which is non-refundable but will be credited against royalties incurred by Capricor for the year in which the minimum annual royalty becomes due.

The JHU Exosome License Agreement will, unless sooner terminated, continue in each country until the date of expiration of the last to expire patent included within the patent rights in that country, or if no patents issue, then for 20 years. The JHU Exosome License Agreement may be terminated by Capricor upon 90 days’ written notice in its discretion and with 60 days’ notice with respect to any particular patent or application or as to any particular licensed product. The JHU Exosome License Agreement may also be terminated by either party if it fails to perform or otherwise breaches any of its obligations and fails to cure such breach within a 60-day cure period commencing upon notice. A material breach by Capricor may include (a) a delinquency with respect to payment or reporting; (b) the failure by Capricor to timely achieve a specified milestone or otherwise failing to diligently develop, commercialize, and sell licensed products throughout the term of the JHU Exosome License Agreement; (c) non-compliance with record keeping or audit obligations; (d) voluntary bankruptcy or insolvency of Capricor; and (e) non-compliance with Capricor’s insurance obligations.

task completion review, analysis of expenses against budgeted amounts, analysis of work performed against approved contract budgets and payment schedules, and recognition of any changes in scope of the services to be performed. Certain CRO and significant clinical trial vendors provide an estimate of costs incurred but not invoiced at the end of each quarter for each individual trial. These estimates are reviewed and discussed with the CRO or vendor as necessary, and are included in R&D expenses for the related period. For clinical study sites which are paid periodically on a per-subject basis to the institutions performing the clinical study, we accrue an estimated amount based on subject screening and enrollment in each quarter. All estimates may differ significantly from the actual amount subsequently invoiced, which may occur several months after the related services were performed.
