Exhibit 10.55

APPENDIX 1

ACCELERATION CONDITIONS

The acceleration of the vesting of 50% of the Option is subject to the conditions set forth in this Appendix 1 (the “Conditions”).

First, the Conditions are based on “Adjusted EBITDA” performance. Adjusted EBITDA, for the purpose of the Conditions, has the meaning given to the term “Segment EBITDA” in the Annual Report on Form 10-K for the Company for the period ending June 30, 2018, where the “segment” shall refer to Paragon Bioservices, Inc. (“Paragon”); provided, however, that (a) if and to the extent that the Company or any of its subsidiaries, other than Paragon, incurs any cost that Paragon would have incurred absent the acquisition of Paragon by the Company (the “Acquisition”)(e.g., the incremental costs to provide legal services to Paragon in connection with customer contracts, whether provided by outside counsel or Company personnel), such cost will be treated as a Paragon cost for the purpose of computing Paragon’s Adjusted EBITDA, (b) any revenue that is accelerated from a period after 2020 into 2020 due to any contract cancellation or buyout will not be deemed received in such year for the purpose of computing Paragon’s Adjusted EBITDA, and (c) all employee retention costs agreed, prior to the closing of the Acquisition, between the Company and Paragon in connection with the Acquisition will be excluded from the calculation of Adjusted EBITDA regardless of when paid or accrued.

Second, Paragon’s Adjusted EBITDA during the fiscal year commencing July 1, 2019 and ending June 30, 2020 (“FY2020”) must exceed (a) 120% multiplied by (b) $74 million.

Third, the Adjusted EBITDA for FY2020 will be fixed for the purpose of the Conditions when the Compensation & Leadership Committee of the Company’s board of directors certifies to whether the Conditions are satisfied following receipt of the Company’s audited financial results for FY2020.

Fourth, the Conditions also require that the Participant remains President, Gene Therapy or in another position mutually acceptable to the Participant and the Company during the period from the closing of the Acquisition through the date of such certification.
