For the period January 1, 2013 through December 31, 2013, Chevron Corporation has identified one
product (a catalyst) contracted by a subsidiary of the Corporation (the Corporation together with its
subsidiaries, “Chevron”) to be manufactured containing a “conflict mineral” that is necessary to the
product’s functionality, as defined and within the meaning of Section 13(p) of the Securities Exchange
Act of 1934 and Rule 13p-1 and Form SD promulgated thereunder (collectively, the “Conflict Mineral
Rules”). Chevron conducted in good faith a reasonable country of origin inquiry regarding the conflict
mineral contained in the product. The inquiry was reasonably designed to determine whether the conflict
mineral contained in the product originated in the Democratic Republic of the Congo (“DRC”) or any
country adjoining the DRC (collectively, a “Covered Country”), or was from recycled or scrap sources.
The inquiry included obtaining written representations from each supplier of the product stating that (i)
the supplier conducted its own reasonable country of origin inquiry within the meaning of the Conflict
Mineral Rules with respect to the conflict mineral included in the product manufactured for Chevron; and
(ii) based on that inquiry, the supplier determined that the conflict mineral did not originate in a Covered
Country or was from recycled or scrap sources, or that the supplier has no reason to believe that the
conflict mineral originated in a Covered Country. Based on this inquiry, Chevron has determined that it
has no reason to believe that the conflict mineral may have originated in a Covered Country.
In addition, Chevron uses catalysts containing a conflict mineral in the refining process for products sold
by Chevron. These catalysts are not intended to be consumed in the refining process and, therefore, no
traces of the conflict mineral should remain in the products sold by Chevron. Accordingly, we do not
believe these products are within the scope of the Conflict Mineral Rules. Nevertheless, we have
conducted in good faith a reasonable country of origin inquiry with respect to the conflict mineral as
described above. Based on this inquiry, Chevron has determined that it has no reason to believe that the
conflict mineral may have originated in a Covered Country
