<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 <FONT
STYLE="white-space:nowrap">13p-1</FONT> and Form SD (the &#147;Rule&#148;) promulgated under the Securities Exchange Act of 1934, as amended, for the reporting period January&nbsp;1, 2017 to December&nbsp;31, 2017. </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 <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">country-of-origin</FONT></FONT> 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. </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 to one product, which is referred to in this Report as the &#147;Covered Product&#148;: (i) 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 2017. 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 <FONT STYLE="white-space:nowrap">Country&#150;of-Origin</FONT> 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 <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">country-of-origin</FONT></FONT> 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 several hundred electronic components purchased from over 60 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
primarily third-party suppliers or distributors 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 does not make any purchases in any of the Covered Countries. Therefore, Cerus </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">
must rely on its direct supplier and its supplier&#146;s upstream component manufacturers to provide information on the origin of the Conflict Minerals contained in the components and materials
used in the manufacture of the Illuminator and the applicable smelters and refiners of Necessary Conflict Minerals in Cerus&#146; supply chain. The information provided by Cerus&#146; direct supplier and its supplier&#146;s upstream component
manufacturers may be inaccurate or incomplete or subject to other irregularities. In addition, because of Cerus&#146; relative location within the supply chain in relation to the actual extraction and transport of Conflict Minerals, Cerus&#146;
ability to verify the accuracy of information reported by its direct supplier and its supplier&#146;s upstream component manufacturers is limited. Accordingly, Cerus cannot provide absolute assurance regarding the source and chain of custody of the
Necessary Conflict Minerals in the Illuminator. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Cerus&#146; amended agreement with its direct supplier, among other things, requires the supplier to
(i)&nbsp;use its best efforts to source materials for the manufacture of the Illuminator that do not contain Conflict Minerals, and (ii)&nbsp;deliver to Cerus a full report each year identifying the sources of any Conflict Minerals, if any,
contained in the Illuminator. As in the prior year, in 2017, Cerus&#146; direct supplier manufactured two versions of the Illuminator and provided to Cerus full reports for both the INT100 and INT100G2 Illuminators manufactured in 2017
(collectively, the &#147;2017 Report&#148;). The 2017 Report identifies the suppliers or distributors of components in the INT100 and INT100G2 Illuminators that contained Necessary Conflict Minerals that (a)&nbsp;did not originate from the Covered
Countries, (b)&nbsp;are unknown to have originated from the Covered Countries, or (c)&nbsp;were not found by the third-party software program. With respect to the INT100 Illuminator, of the 396 components analyzed, 25% did not originate from a
Covered Country or did not originate from a smelter or refiner known to finance or benefit armed groups in the Covered Countries (such status, <FONT STYLE="white-space:nowrap">&#147;Non-Covered</FONT> Country of Origin&#148;), 73% were of an unknown
origin, and 1% were not found by the third-party software program; as compared to 31%, 67% and 1%, respectively, in the report for INT100 Illuminators manufactured in 2016. Of the 367 components that were analyzed for the INT100G2 Illuminator, 19%
had a status of <FONT STYLE="white-space:nowrap">Non-Covered</FONT> Country of Origin, 77% were of an unknown origin, and 3% were not found by the third-party software program, as compared to 59%, 38% and 3%, respectively, in the report for INT100G2
Illuminators manufactured in 2016. Due to the significant decrease in the percentage of components that were not classified as <FONT STYLE="white-space:nowrap">Non-Covered</FONT> Country of Origin in the 2017 Report compared to 2016, Cerus further
investigated the reason for such difference and found that of the nearly 400 components analyzed, 149 components changed from a <FONT STYLE="white-space:nowrap">Non-Covered</FONT> Country of Origin status in the report for 2016 to an unknown origin
in the 2017 Report. Cerus further determined that two upstream suppliers provided a majority of such 149 components and both such suppliers answered &#147;unknown&#148; instead of &#147;no&#148; on its EICC template when asked <I>Do any of the
smelters in your supply chain source the 3TG from the covered countries?</I> In addition, the EICC template provided by one of the two upstream suppliers indicated that it had a 78% increase in the number of smelters included on their smelter list
from 2016 to 2017, suggestive of a broader sourcing program with potentially more unknown origins of Conflict Minerals. The other upstream supplier indicated to Cerus that it frequently changes its upstream suppliers and that those suppliers, in
turn, may also be changing its sourcing smelters, which similarly impacts the potential for unknown origins of Conflict Minerals. As a result of the disparity in the percentage of components from <FONT STYLE="white-space:nowrap">Non-Covered</FONT>
Countries of Origins between 2016 and 2017, Cerus has decided to undertake, with its supplier, additional technical review to determine if any alternative suppliers are available for certain components used in the manufacture of the Illuminators.
However, based on the potential impact that changing components may have on the regulatory approval for the Illuminators, in addition to Cerus&#146; downstream position in the supply chain for components of the Covered Products, Cerus cannot ensure
that such additional technical review will result in sourcing Illuminator components from <FONT STYLE="white-space:nowrap">non-Covered</FONT> Countries. Additionally, because Cerus is unlikely to know about future sourcing changes by upstream
suppliers of the Illuminator components until the annual EICC templates are published, Cerus may continue to experience year-over-year uncertainty in its effort to achieve a supply chain that is free of Conflict Minerals sourced from a Covered
Country. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Design of Due Diligence </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Cerus&#146; due

established a reporting protocol under which the Conflict Minerals management team reports risks arising from its diligence exercise to executives of the company. The protocol is designed to enable the Conflicts Minerals management team to report,
among other things, identified risks in the supply chain. Cerus&#146; risk management strategy includes maintaining close contact with its direct supplier in order to (a)&nbsp;obtain the required upstream supplier information for components of the
Covered Product, (b)&nbsp;pursue Cerus&#146; goal of having a conflict-free supply chain, and (c)&nbsp;attempt to influence the selection, to the extent practicable, of alternative upstream suppliers that can provide assurance that their components

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. Cerus was unable to locate any component specification datasheets that were provided as part of Cerus&#146; diligence effort which specified the smelters
or refiners that were the source of Conflict Minerals for the particular component. Most of the smelter information provided was obtained through the EICC templates and were reported at the company level for products manufactured by the supplier;
thus, did not specify the country of origin for Conflict Minerals in the particular components used to manufacture the Illuminator. 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
