[*] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. EXHIBIT 10.2 FIRST AMENDMENT TO SUPPLY AND MANUFACTURING AGREEMENT This First Amendment (Amendment) to the Supply and Manufacturing Agreement dated April 1, 2017 between Cerus Corporation (Cerus) and Porex Corporation (Porex) (the Agreement) is made this 22 day of June 2018. RECITALS A. Cerus and Porex have agreed to make certain changes to the raw material and process to develop Components and such changes have resulted in a change to the cost and expense structure originally contemplated by the Agreement; B. Pursuant to Section 3 of the Agreement, Cerus and Porex have mutually agreed to temporarily modify the pricing for Platelet Wafers set forth on Exhibit D and to proactively set a cost structure for non-production related work. NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged and accepted, the parties hereby agree to amend the Agreement as follows: 1. New Exhibits AA-1, AA-2, AA-3 and AA-4, as set forth in Schedule 1 to this Amendment, shall be attached to the Agreement (inserted between Exhibit A-5 and Exhibit B-1) and incorporated therein by reference. The parties acknowledge and agree that Exhibits AA-1, AA-2, AA-3 and AA-4 set forth the revised specifications for Platelet Wafers manufactured by Porex for Cerus (collectively, the Revised Wafer Specifications). Unless otherwise agreed in writing, Porex shall continue to manufacture and produce Platelet Wafers using the existing specifications for Platelet Wafers until Cerus gives written notice to Porex that Platelet Wafers shall be thereafter manufactured in accordance with the Revised Wafer Specifications. References in the Agreement to Specifications shall be interpreted to include the Revised Wafer Specifications, as applicable. 2. A new Exhibit D-1, as set forth in Schedule 2 to this Amendment, shall be attached to the Agreement and incorporated therein by reference. As of April 1, 2018 and continuing until Cerus determines, in its sole discretion, that the Protocol EPP-029-886 under which Porex is currently operating can be discontinued, the price for Platelet Wafers shall be the prices set forth in Exhibit D-1. Upon Cerus' determination that the Protocol EPP-029- 886 can be discontinued, Cerus shall provide written notice thereof to Porex, along with a new purchase order for Platelet Wafers (the New Pricing PO). On and after the date of such notice, the Pricing table for Platelet Wafers in Exhibit D, as of the date immediately preceding the date of this Amendment, shall be reinstated and apply to Platelet Wafers that are produced pursuant to the New Pricing PO and were also produced after the date of the written notice. References in Section 1.5.1 of the Agreement to Exhibit D shall be amended to include Exhibit D-1, as applicable. 3. The penultimate sentence in Section 1.3 shall be deleted in its entirety and replaced with the following: In no event shall any Purchase Order: require delivery of more than [*] units of [*] and [*] units of [*] in any [*] (the Porex Capacity Limitations). 4. A new Section 1.5.3 shall be added to the Agreement as follows:





1.5.3 Porex will invoice Cerus monthly for Services performed by Porex during the prior month. Unless otherwise expressly provided in the applicable Statement of Work payment to Porex of undisputed fees shall be due [*] days following Cerus' receipt of the invoice submitted by Porex. Payment information, including Tax Identification Number will be included on each invoice.

Cerus shall have the right to accept or reject the Services, or any portion thereof, in writing within [*] days from Porex's completion of the Services. Such acceptance or rejection shall be consistent with the criteria set forth in the Statement of Work, if any. If Cerus does not reject in writing within [*] days, the Services shall be considered accepted by Cerus. Within [*] days of any notice of rejection, Porex shall present a corrective plan of action to Cerus. Upon approval by Cerus of the corrective plan, Porex, at no additional expense to Cerus, shall then make the corrections and, where applicable, Porex shall resubmit the corrected Services to Cerus. For disputed invoices or the disputed portion of an invoice, Cerus shall use reasonable efforts to provide to Porex, in writing, within [*] days, a description of the disputed amounts. Cerus and Porex shall negotiate in a timely, good faith manner to resolve billing queries. Cerus will not have responsibility to pay for identified errors, incomplete or inaccurate items (collectively the invoice errors) which result in increases to previously invoiced amounts if the aforementioned invoice errors are communicated to Cerus later than [*] days from the original invoice date.

5. A new Section 3a shall be added to the Agreement as follows: 3a Non-Production Related Work. From time to time, Cerus may submit to Porex written work orders substantially in the form of Schedule 3 that specify development activities, engineering analysis, part, material and/or fixture design and development, or other services or activities that Cerus requests Porex to perform that are not activities or services that are necessary for the then-current manufacture and production of Components for Cerus under the Agreement (collectively, as defined in each work order, the Services). Each work order shall set forth the terms and conditions (including specifications (if applicable), delivery and performance schedules, and fees) pursuant to which Porex will perform the Services. Upon acceptance of a work order by Porex (in writing), such work order shall become a Statement of Work. If Porex begins to perform services under a work order that has not been formally agreed in writing, then Porex shall bear the costs of any expenses incurred prior to formal written agreement of the Statement of Work. Cerus hereby consents to Porex's use of the Cerus Dedicated Space and Equipment, as specified in a Statement of Work, solely as necessary to perform the Services under that Statement of Work. Such consent shall automatically terminate upon the completion of the applicable Statement of Work and is limited by the terms of the Agreement. In the event of any conflict between the Agreement and a Statement of Work, the Agreement shall control unless the Statement of Work expressly refers to the Parties' intent to alter the terms of the Agreement with respect to that Statement of Work and shall not be construed as an amendment to the terms of the Agreement. 6. A new section titled Pricing for Non-Production Related Work Orders from Cerus is added to Exhibit D as set forth in Schedule 2 attached. Such pricing, upon mutual agreement of the Parties, shall apply to any Statement of Work mutually agreed by the Parties pursuant to Section 3a. 7. No other changes are made to the Agreement, including without limitation, the original Exhibit D, and the Agreement, the Plasma Disk pricing and related information as set forth in Exhibit D remain the same. Except as amended herein, the Agreement shall remain in full force and effect. Capitalized terms not otherwise defined herein shall have the same meanings as set forth in the Agreement. IN WITNESS WHEREOF, the undersigned have caused this First Amendment to be signed, all as of the date first written above.
