                  Re:      Registration Statement on Form S-8

Ladies and Gentlemen:

         In connection with the registration under the Securities Act of 1933,
as amended, by Geron Corporation, a Delaware corporation (the "Company"), of an
aggregate of 300,000 shares of common stock of the Company, par value $0.001 per
share (the "Employee Shares"), issuable under the Company's 1996 Employee Stock
Purchase Plan (the "Employee Plan"), and an aggregate of 500,000 shares of
Common Stock of the Company (the "Directors' Shares" and, together with the
Employee Shares, the "Shares") issuable under the Company's 1996 Directors'
Stock Option Plan (the "Directors' Plan" and, together with the Employee Plan,
the "Plans"), on Form S-8 to be filed with the Securities and Exchange
Commission on July 23, 2003 (the "Registration Statement"), you have requested
our opinion with respect to the matters set forth below.

         In our capacity as your special counsel in connection with such
registration, we are familiar with the proceedings taken and to be taken by the
Company in connection with the authorization, issuance and sale of the Shares.
In addition, we have made such legal and factual examinations and inquiries,
including an examination of originals or copies certified or otherwise
identified to our satisfaction, of such documents, corporate records and
instruments as we have deemed necessary or appropriate for purposes of this
opinion.

         In our examination, we have assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals, and the
conformity to authentic original documents of all documents submitted to us as
copies.

         We are opining herein as to the effect on the subject transaction only
of the General Corporation Law of the State of Delaware, and we express no
opinion with respect to the applicability thereto, or the effect thereon, of the
laws of any other jurisdictions, or, in the case of Delaware, any other laws, or
as to any matters of municipal law or the laws of any local agencies within any
state.

         Subject to the foregoing, it is our opinion that the Shares to be
issued under the Plans have been duly authorized, and upon the issuance and
delivery of the Shares in the manner contemplated by the Plans, and assuming the
Company completes all actions and proceedings required on its part to be taken
prior to the issuance and delivery of the Shares pursuant to the terms of the
Plans, including, without limitation, collection of required payment for the
Shares, the Shares will be validly issued, fully paid and nonassessable.

         We consent to your filing this opinion as an exhibit to the
Registration Statement.

                                                     Very truly yours,

                                                     /s/ Latham & Watkins LLP
