                        SEPARATION AGREEMENT AND RELEASE

         This Separation Agreement and Release ("Agreement") is made this 7th
day of February, 2001 (the "Effective Date") by and between Storage Technology

         WHEREAS, Employee was employed by the Company as Chief Administrative
Officer;

         WHEREAS, Employee signed a Storage Technology Corporation Proprietary
Rights Agreement in consideration of employment with the Company;

         WHEREAS, Employee's employment with the Company and Corporate Officer
Employment Agreement dated October 1, 1999 (the "Employment Agreement") are both
terminated effective February 14, 2001 (the "Termination Date"); with salary and
benefits paid through the Termination Date;

         WHEREAS, the Company has agreed to provide Employee with valuable
consideration to facilitate Employee's transition from the Company;

         WHEREAS, Employee has agreed to release the Company from any claims
arising from or related to Employee's employment relationship with the Company;

         WHEREAS, this Separation and Release Agreement supersedes all previous
oral and written agreements regarding Employee's employment with Storage
Technology Corporation, provided, however, that the terms and conditions of
Employee's Employment Agreement, to the degree that they do not conflict with
the terms and conditions of this Separation Agreement, shall remain in full
force and effect;

         NOW THEREFORE, in consideration of the mutual promises made herein, the
Company and Employee (jointly referred to as "the Parties") hereby agree as
follows:

         1. CONSIDERATION: The Company agrees to pay Employee a separation
payment of $250,000.00, which amount equals one year's current base salary, said
amount to be paid to Employee less applicable withholding (the "Consideration").
Employee acknowledges that she is not entitled to the Consideration recited in
this Separation Agreement and Release but for the execution of this Separation
Agreement and Release. The Consideration will be paid within thirty days upon
the full execution and acceptance of this Agreement and upon expiration of the
revocation period as described in Paragraph 6 below. The Parties acknowledge and
agree that 25% of the severance payment is made solely in consideration of
Employee executing and not revoking the ADEA Waiver and Release as set forth in
Paragraph 6 below.

         2. STOCK OPTIONS & RESTRICTED STOCK: As of the Termination Date,
Employee agrees and acknowledges that she has 29,742 vested shares of the
Company's common

stock under the 1995 Storage Technology Corporation Equity Participation Plan.
Employee's stock will continue to be governed by the respective Storage
Technology Equity Participation Plan as listed above. Employee shall not be
entitled to continue vesting in Company stock after the Termination Date.
Pursuant to the terms of the company's 1995 Equity Participation Plan, Employee
will have ninety (90) days from the Termination Date to exercise the vested
options. On the Termination Date, the Company shall exercise its right to
repurchase all of Employee's unvested restricted stock.

         3. BENEFITS: Employee's insurance benefits (medical, dental, long-term
disability, accidental death and dismemberment and life insurance) will cease on
the Termination Date, subject to Employee's rights to continue her health
insurance under COBRA. Employee will not be entitled to accrual of any employee
benefits, including, but not limited to, vacation and personal time off
benefits, after the Termination Date. In addition to the consideration recited
above, the Parties further acknowledge and agree that Employee will be paid the
lump sum payment of $8,753.24, which represents twelve (12) months of COBRA
health insurance premium payments for family medical and dental coverage.

         4. PAYMENT OF SALARY: Employee acknowledges and represents that the
Company has paid all salary, wages, bonuses, earned unused vacation, and any and
all other benefits and compensation due to Employee up to the Termination Date.
The parties further acknowledge and agree that Employee is entitled to receive a
performance bonus in the amount of 50% of Employee's current base salary
($137,500.00) for the achievement of performance objectives through December 31,
2000, said bonus to be paid on the Termination Date or on the next paycheck.
Employee acknowledges and agrees that with the exception of the bonus payment
referenced herein, she is not eligible or entitled to receive any other type of
bonus payment by the Company for the calendar years 2000 or 2001. Employee
specifically acknowledges that she is not entitled to receive any type of bonus
through the Management By Objective Bonus Program ("MBO Program") or any type of
bonus through the Retention Bonus Program paid by the Company for the calendar
years 2000 or 2001.

         6. ACKNOWLEDGMENT OF WAIVER OF CLAIMS UNDER ADEA: Employee acknowledges
that she is waiving and releasing any rights she may have under the Age
Discrimination in Employment Act of 1967, as amended ("ADEA") and that this
