Item 1.01    Amendment of Material Definitive Agreement.

     On October 2, 2006, the Compensation Committee of the Board of Directors of
Geron Corporation (the "Company") approved an amendment and restatement to the
Company's severance plan (the "Severance Plan") effective October 2, 2006.

     All of the Company's employees are eligible to participate in the Severance
Plan. The amendment redefines certain employment positions (the "Covered
Positions") and the severance payment amount for such Covered Positions.
Eligible participants under the plan who are terminated for any reason other
than "cause" (as defined in the Severance Plan) and have signed a mutually
acceptable separation agreement shall hereafter be entitled to (i) a lump sum
payment equal to the participant's then-current base salary for the Severance
Period (as defined in the Severance Plan); and (ii) payment of premiums required
for the continuation of health, dental and vision insurance under the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA")
through the earlier of the end of the applicable Severance Period or when other
employment offering health care coverage is obtained.

     The amendment also provides for certain limitations with respect to the
timing of payments under the Severance Plan to ensure compliance with the
requirements of Section 409A of the Internal Revenue Code, which was enacted as
part of the American Jobs Creation Act of 2004, and the proposed regulations
issued by the Treasury Department under Section 409A.

     Pursuant to the requirements of the Securities Exchange Act of 1934, the
registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.
