Ladies and Gentlemen:
We have acted as counsel to XOMA Corporation (the Company), a Delaware corporation, and you have requested our opinion with respect to certain matters in connection with the filing by the Company of a registration statement on Form S-8 (the Registration Statement) with the Securities and Exchange Commission covering the offering of up to 5,350,000 shares of the Companys common stock, par value $0.0075 per share (the Shares), pursuant to its Amended and Restated 2010 Long Term Incentive and Stock Award Plan (the Plan).
In connection with this opinion, we have examined the Registration Statement and related prospectus, the Companys certificate of incorporation and by-laws, each as amended, the Plan, and such other documents, records, certificates, memoranda or other instruments as we deem necessary as a basis for this opinion. We have assumed the genuineness and authenticity of all documents submitted to us as originals and the conformity to originals of all documents submitted to us as copies thereof.
On the basis of the foregoing, and in reliance thereon, we are of the opinion that the Shares, when sold and issued in accordance with the Plan, the Registration Statement and related prospectus, will be validly issued, fully paid, and nonassessable (except as to shares issued pursuant to certain deferred payment arrangements, which will be fully paid and nonassessable when such deferred payments are made in full).
We consent to the filing of this opinion as an exhibit to the Registration Statement.
Sincerely,
COOLEY LLP
