                        EXECUTIVE COMPENSATION PLAN 2001

NAME:                          MARK MAYS
TITLE                          VP, DIRECTOR BACK UP ENGINEERING
BASE SALARY:                   $230,000
ON-PLAN BONUS:                 50% OF BASE SALARY ($115,000)
--------------------------------------------------------------------------------
EXHIBIT C
By signing this Executive Compensation Plan 2001 ("Plan"), you hereby agree that
the terms of this Plan shall be in addition to the terms of the Employment
Agreement between you and Dot Hill dated August 2, 1999 ("Employment
Agreement"), and shall replace and supercede the terms of Exhibit C of the
Employment Agreement with respect to your base salary and bonus for the year
2001. Otherwise, the terms of our Employment Agreement remain unchanged. For any
period of time after December 31, 2001, your base salary and bonus shall be
subject to change, as determined by Dot Hill's Board of Directors and/or
Compensation Committee ("BOD").

BASE SALARY
Total base salary will be paid in regular periodic payments, in accordance with
Company Policy, less required payroll deductions and withholdings.

BONUS
Bonus is calculated based on a percentage of base salary.

Bonus will be paid once annually as soon as practicable after an audit of the
Company's fiscal year 2001 results has been completed and after the Dot Hill
Board of Directors and/or Compensation Committee ("BOD") has approved the
payment.

Bonus is tied to Dot Hill's overall 2001 annual operating plan.
          a.   50% of bonus is tied to achieving on-plan revenue of $160,000,000
               for 2001
          b.   50% of bonus is tied to achieving on-plan net income of
               $9,865,000 for 2001
          c.   If at the end of 2001, the year-end revenue AND the net income is
               equal to or less than 85% of the on-plan targets, no bonus will
               be paid.
          d.   For each 1% increase above 85% of on-plan revenue and,
               separately, on-plan net income, a bonus equal to 3.33% of on-plan
               bonus will be paid, with no cap. For example, assume that the
               Company attains 112% of on-plan revenue and 100% of on-plan for
               net income, and the entire on-plan bonus is $100,000. Bonus based
               on revenue will be paid by multiplying 3.33 by (112% - 85%),
               which equals 89.91%, and then multiplying that by the on-plan
               bonus of $100,000 equaling $89,910. Further, the bonus based on
               net income would be calculated by multiplying 3.33 by (100% -
               85%), which equals 50%, and then multiplying that by the on-plan
               bonus of $100,000 equaling $50,000. The total bonus payout would
               be $89,910 + $50,000 or $139,910.
          e.   Overachievement of on-plan bonus is possible based on Dot Hill's
               exceeding its 2001 revenue and/or net income targets, as per "d"
               above.

TERMS
a.   You must be an employee in good standing on the date of payout to be
     eligible for the bonus payout.
b.   The base salary and bonus structure may be revised by the BOD at any time,
     with no notice.
c.   You are eligible for all benefits afforded Regular Full-time Exempt
     employees as set forth in the most current version of the Dot Hill Employee
     Handbook.
d.   The terms, conditions, and benefits of your employment with Dot Hill
     Systems Corporation are governed by the terms of the Employment Agreement
     and the standard Company policies and benefits. No verbal promises, verbal
     commitments, or implied promises will alter the Employment Agreement or
     these standard policies and benefits.
e.   The employment relationship between the parties is "at will" and may be
     terminated by Dot Hill at any time.

         In consideration of the payments and other benefits set forth in my
employment offer letter, to which this form is attached, I hereby furnish Box
Hill Systems Corp. (the "Company") with the following release and waiver.

         I hereby release, and forever discharge the Company, its officers,
directors, agents, employees, stockholders, successors, assigns and affiliates,
of and from any and all claims, liabilities, demands, causes of action, costs,
expenses, attorneys' fees, damages, indemnities and obligations of every kind

Company.

         I acknowledge that, among other rights, I am waiving and releasing any
rights I may have under ADEA, that this waiver and release is knowing and
voluntary, and that the consideration given for this waiver and release is in
addition to anything of value to which I was already entitled as an employee of

Older Workers Benefit Protection Act, that: (a) the waiver and release granted
herein does not relate to claims which may arise after this release and waiver
is executed; (b) I have the right to consult with an attorney prior to executing
this release and waiver (although I may choose voluntarily not to do so); and
(c) if on the date of execution of this release and waiver I am age 40 or older,
then (I) I have twenty-one (21) days from the date I receive this release and
waiver, in which to consider this release and waiver (although I may choose
voluntarily to execute this release and waiver earlier); and (II) I have seven
(7) days following the execution of this release and waiver to revoke my consent
to this release and waiver. This release and waiver shall be effective as of the
date of execution hereof; provided that if on the date of execution of this
release and waiver I am age 40 or older, then this release and waiver shall not
be effective until the foregoing seven (7) day revocation period has expired.
The date

QUARTERLY PERFORMANCE BONUS

Each quarter, you shall be eligible for a performance bonus of up to 50% of your
base salary for such quarter (Quarterly Bonus). The Quarterly Bonus shall be
based on the following formula, and on the Company's Business Plan, as approved
by the Board of Directors, for such quarter:

FORMULA

1.       REVENUE-BASED BONUS: Half of the Quarterly Bonus shall be based on
revenue. If the Company meets the Business Plan revenue goals for any given
quarter, you shall be entitled to half of the Quarterly Bonus (25% of the
your base salary for such quarter) for performance during the quarter. If the
Company fails to meet the Business Plan revenue goals for a given quarter,
then the revenue-based bonus shall be paid as follows:

         if the Company attains less than 75% of the Business Plan revenue
         goals, you shall not receive any revenue-based bonus for that quarter.
         For attaining levels of revenue between 75% and 100% of plan, you shall
         receive 2% of the total Quarterly Bonus for every 1% of revenue above
         75%.

2.       INCOME-BASED BONUS: Half of the Quarterly Bonus is to be based on
net income. If the Company meets the Business Plan net income goals for any
given quarter, then you shall be entitled to half of the Quarterly Bonus (25%
of your salary for such quarter) for performance during that quarter. If the
Company fails to meet the Business Plan net income goals for a given quarter,
then the net income-based bonus shall be paid as follows:

         0.5% of the Quarterly Bonus, payable for each 1% achieved of the net
         income line of the Business Plan, up to a maximum of 100%.
