                        SEPARATION AGREEMENT AND RELEASE

       This Separation Agreement and Release (together with its attachments, the
"Agreement") is made and entered into as of December 14, 2001 by and between
Transmeta Corporation, a Delaware corporation (together with its subsidiaries,
successors and assigns, the "Company"), and David P. Jensen (the "Employee").

       WHEREAS, the Employee has been employed by the Company in the office of
Vice President of Operations;

       WHEREAS, the Employee and the Company terminated that employment
relationship, and the Employee resigned his position as an officer of the
Company effective November 16, 2001;

       WHEREAS, the Company believes that it is in the best interest of its
shareholders to enter into a comprehensive separation agreement and release with
the Employee;

       WHEREAS, the Employee and the Company (the "Parties") desire to settle
fully and finally any and all differences between them, and so have negotiated
and agreed to a final settlement of their respective rights, obligations and
liabilities;

       NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the Employee and the Company hereby
agree as follows:

       1. Resignation. The Parties agree that as of November 16, 2001, the
Employee has tendered, and the Company has accepted, his resignation as Vice
President of Operations and any and all other offices that he may have held with
the Company or any affiliate or subsidiary of the Company (the "Resignation
Date"). From the Resignation Date through and including December 31, 2001, the
Employee shall continue as an employee of the Company and provide such services
as are requested by the Company's Chief Executive Officer or President.

       2. Severance Payment. The Company shall continue to pay to the Employee
his normal salary and such other incentives and benefits as he might earn,
subject to ordinary tax withholding, in accordance with its ordinary payroll
schedule through and including December 31, 2001. The Company shall also make to
the Employee a final lump sum severance payment of $135,000, subject to the
Employee's continued compliance with the terms and covenants set out in this
Agreement, on January 2, 2002. The Employee acknowledges that such $135,000 sum
represents a gross amount before all applicable federal, state and local
withholding taxes that are required to be deducted by the Company.

       3. Benefits. From the Resignation Date through and including December 31,
2001, the Company shall continue to make available to the Employee all Company
benefits that were available to and received by the Employee immediately before
the

Resignation Date. The Employee and each eligible dependent who constitutes a
qualified beneficiary, as defined in Section 4980B(g)(1) of the Internal Revenue
Code of 1986, as amended, will be eligible to continue coverage under the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"),
within the time period prescribed pursuant to COBRA. After December 31, 2001,
upon the Employee's timely COBRA election, and to the extent consistent with the
terms of the Company's existing health plan, the Company will continue to pay
for the Employee's present election of group health benefits (including medical,
dental, and vision coverage) for the Employee and his dependents until he finds
employment providing comparable health benefits, or through and including
December 31, 2002, whichever occurs first.

       4. Reimbursements. The Company shall promptly reimburse the Employee for
any reasonable business expenses properly incurred by the Employee through
December 31, 2001 and duly submitted by the Employee for reimbursement.

       5. Stock Options. With respect to the stock options granted to the
Employee by the Company, the Parties acknowledge and agree to the following:

       a. The parties acknowledge and agree that the stock option granted to the
Employee on July 26, 2001 to purchase 100,000 shares of the Company's common
stock at an exercise price of $3.11 per share is hereby canceled and terminated
in full. The Employee acknowledges and agrees that he has not exercised that
option to purchase any shares of the Company's common stock and that, effective
as of the date of this Agreement, he shall have no surviving right, title or
interest in that stock option.

       b. The Parties acknowledge that they previously entered into that certain
Stock Repurchase Agreement on November 27, 2001 (the "Stock Repurchase
Agreement"), pursuant to which (1) the Company exercised its right to repurchase
at the market price of $3.22 per share all 550,000 shares of the Company's
common stock that originated in the stock option granted to the Employee by the
Company on February 18, 2000 to purchase such shares for $3.62 per share (the
"Stock Option"), (2) the Company paid the price for that stock repurchase by
canceling debt owed by Employee under the promissory note issued by the Employee
for the purpose of exercising the Stock Option (the "Note") in an amount equal
to the repurchase price, and (3) the Company canceled the Note and any and all
remaining debts or obligations owed by the Employee under the Note. The Employee
acknowledges that he is solely responsible for any and all tax consequences
arising from or relating to the cancellation of the Note by the Company;
provided, however, that the Company shall make timely and appropriate tax
withholding payments in a total amount not to exceed $420,000 in the aggregate
on behalf of or for the benefit of the Employee relating to the cancellation of
the Note.

       c. The Employee acknowledges and agrees that the Company has not issued
to him any option to purchase common stock of the Company other than the stock
options described above in sections 5.a and 5.b of this Agreement, and that he
has no other right, title or interest in or to any option or right to acquire
common stock of the Company.
