<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">This Conflict Minerals Report (the &#147;Report&#148;) of Cerus Corporation (&#147;Cerus&#148;) has been prepared pursuant to Rule 13p-1 and Form SD (the
&#147;Rule&#148;) promulgated under the Securities Exchange Act of 1934, as amended, for the reporting period January&nbsp;1, 2015 to December&nbsp;31, 2015. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Rule requires disclosure of certain information when a company manufactures or contracts to manufacture products and the minerals specified in the Rule
are necessary to the functionality or production of those products. The specified minerals, which are collectively referred to in this Report as the &#147;Conflict Minerals,&#148; are gold, columbite-tantalite (coltan), cassiterite and wolframite,
including their derivatives, which are limited to tantalum, tin and tungsten. The &#147;Covered Countries,&#148; for the purposes of the Rule and this Report, are the Democratic Republic of the Congo, the Republic of the Congo, the Central African
Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania, Zambia and Angola. As described in this Report, Cerus contracts to manufacture one product which contains Conflict Minerals that are necessary to the functionality or production of such
product (the &#147;Necessary Conflict Minerals&#148;). As discussed below, following the performance of a reasonable country-of-origin inquiry (&#147;RCOI&#148;) and due diligence on the source and chain of custody of the Necessary Conflict
Minerals, Cerus has reasonably concluded that is unable to determine whether, with respect to the Covered Product (as defined below), Necessary Conflict Minerals were used, directly or indirectly, to finance or benefit armed groups in the Covered
Countries and that, therefore, the Covered Product is &#147;DRC Conflict Undeterminable.&#148; </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Description of Cerus&#146; Product Covered by this
Report </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Cerus is a biomedical products company focused on the field of blood safety. Cerus&nbsp;currently markets and sells the INTERCEPT Blood System
for both platelets and plasma (the &#147;platelet system&#148; and &#147;plasma system,&#148; respectively) in the United States; certain countries in Europe, the Commonwealth of Independent States, the&nbsp;Middle East, and Latin America&nbsp;and
selected countries in other regions around the world. Both the platelet system and plasma system employ the same technology. Platelet or plasma components collected from blood donors are transferred into plastic INTERCEPT disposable kits and are
mixed with Cerus&#146; proprietary compound, amotosalen, a small molecule compound which has an affinity for nucleic acid. The disposable kits are then placed in the INTERCEPT Illuminator, an illumination device (the &#147;Illuminator&#148;), where
the mixture is exposed to ultra-violet A, or UVA, light. If pathogens such as viruses, bacteria or parasites are present in the platelet or plasma components, the energy from the UVA light causes the amotosalen to bond with the nucleic acid. Since
platelets and plasma do not rely on nucleic acid for therapeutic efficacy, the INTERCEPT Blood System is designed to preserve the therapeutic function of the platelet and plasma components when used in human transfusions. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">This Report relates one product, which is referred to in this Report as the &#147;Covered Product&#148;: (i)&nbsp;for which Conflict Minerals are necessary to
its functionality or production; (ii)&nbsp;that were manufactured, or contracted to be manufactured, by Cerus; and (iii)&nbsp;for which the manufacture was completed during calendar year 2015. For the Reporting Period, the Illuminator was the only
Covered Product. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Reasonable Country&#150;of-Origin Inquiry </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Cerus has conducted a good faith reasonable country-of-origin inquiry regarding the Necessary Conflict Minerals. This good faith RCOI was reasonably designed
to determine whether any of the Necessary Conflict Minerals originated in the Covered Countries and whether any of the Necessary Conflict Minerals may be from recycled or scrap sources. Cerus&#146; RCOI comprises the conduct described under the
caption &#147;Description of Due Diligence Measures &#151; Identify and Assess Risk in the Supply Chain&#148; below. Because, as a result of the RCOI, Cerus was unable to determine the countries of origin of all of the Necessary Conflict Minerals in
its supply chain, Cerus also performed due diligence on the source and chain of custody of the Necessary Conflict Minerals. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Cerus&#146; Due Diligence
Process </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Illuminator is manufactured by Cerus&#146; supplier according to Cerus-provided specifications and contains over 400 electronic components
purchased from over 50 of Cerus&#146; supplier&#146;s upstream component manufacturers. Due to the Illuminator&#146;s level of regulatory classification in most jurisdictions where it is sold, changes to its design or components will require
significant regulatory review and approval. The supply chain for the components of the Illuminator is complex and includes many third-party suppliers between the ultimate manufacturer of the Illuminator and the original sources of the Necessary
Conflict Minerals contained therein. Cerus does not purchase any Necessary Conflict Minerals directly from mines, smelters or refiners and do not make any purchases in any of the Covered Countries. Therefore, Cerus must rely on its direct

Minerals management team have worked with Cerus&#146; supplier to identify a subset of Illuminator components for which Cerus&#146; supplier will conduct a technical review to determine if any alternative suppliers are available that can provide
assurance that such components do not contain any Conflict Minerals and the potential additional cost, if any, of sourcing such components from an alternative up-stream supplier. </P>

<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Conclusions </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Due to the large number of suppliers
upstream of the Illuminator supplier, as well as the relatively small percentage of the Illuminator supplier&#146;s business that the manufacture of the Illuminator comprises, Cerus was unable to obtain complete information regarding the source and
chain of custody for all of the Conflict Minerals contained in components of the Illuminator. The EICC templates that were completed by component suppliers and provided as part of Cerus&#146; diligence effort included information only at the company
level (i.e., identifying smelters and refiners that process Conflict Minerals for all of the products of that supplier) and did not specify which smelters or refiners were the source of Conflict Minerals in the particular components furnished to the
Illuminator supplier for use in the Illuminator. Similarly, the EICC templates did not specify the country of origin for Conflict Minerals in the particular components furnished to the Illuminator supplier. As a result, based on the diligence
performed to date, Cerus determined that it did not have sufficient information to reasonably or reliably identify the particular smelters or refiners that processed the Conflict Minerals contained in the Illuminator or the country of origin of such
Conflict Minerals, and thus did not list the smelters or refiners or countries of origin in this Report. To determine the mines or location of origin of the Conflict Minerals with the greatest possible specificity, Cerus performed the due diligence
measures described above. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Future Due Diligence and Risk Mitigation.&nbsp;</I>Cerus intends to take the following steps to improve its due diligence:
(a)&nbsp;continue to maintain close contact with the Illuminator supplier with the goal of having a conflict-free supply chain; (b)&nbsp;increase the transparency of Cerus&#146; supply chain by determining and identifying the affected
suppliers&#146; smelters and countries of origin of Conflict Minerals; and (c)&nbsp;review supplier contracts to include a clause relating to sourcing of Conflict Minerals. </P>
