Dear Bo:

On behalf of the Board of Directors (the Board) of Silicon Graphics, Inc. (the Company), it is our pleasure to offer you the position of Chief Executive Officer of the Company. The terms of our
offer and the benefits provided by the Company are as set forth below. If you accept the terms of our offer and the conditions of our offer are satisfied, it is anticipated that your employment with the Company will commence on April 9, 2007
(the Start Date).



|1. | Position, Duties and Responsibilities.
|-- | --------------------------------------

a. You
shall be the Chief Executive Officer of the Company and shall, in such capacity, report to the Board. Your duties and responsibilities will be determined from time to time by the Board, and will be consistent with your position.

b. You will be appointed to the Board as a Class I director effective as of your first day of employment with the Company. You will serve on such
Committees of the Board as elected or appointed by the Board.

c. During your employment and except for periods of illness or vacation, you
shall devote your full business time, ability and attention to the business of the Company, and shall not engage in or perform duties for any other person or entity which interfere with the performance of your duties hereunder. If you wish to hold
board of director positions on outside civic organizations, reasonable time will be made available to fulfill your duties in that regard as long as those activities do not interfere with the performance of your duties hereunder. Any outside
commercial board of directors positions will be subject to written approval by the Board.



|2. | Base Salary and Bonus.
|-- | ----------------------

a. Base Salary. As
compensation for your services hereunder, including your services as a member of the Board, you shall receive an annual base salary of $600,000, payable in accordance with the Companys regular payroll schedule. Your base salary will be
reviewed, and may be adjusted in the discretion of the Board, on an annual basis.



---

b. Fiscal Year Bonus. You will be eligible to receive a cash bonus each fiscal year based upon the
achievement of specified objectives established for the Company and for your position under the Companys executive bonus program, as such program may be modified and established for each fiscal year (the Executive Bonus Program).
Your participation in such bonus programs will commence on the first day of the Companys 2008 fiscal year. You will be responsible for establishing the proposed terms and conditions of this program, which shall be subject to the approval of
the Compensation Committee of the Board (the Compensation Committee). Your target bonus under the Executive Bonus Program shall be 100% of your then current annual base salary and the amount of bonus you are paid is to be determined by
the Compensation Committee based upon your and the Companys achievement of all relevant objectives, as determined by the Board in its reasonable discretion. For the Companys 2007 fiscal year, you will be guaranteed a cash bonus equal to
100% of your base salary, prorated for the days in fiscal 2007 that you are actually employed by the Company (the Guaranteed Bonus). The Guaranteed Bonus shall be paid in a lump sum at the same time as all 2007 fiscal year executive
bonuses are scheduled to be paid, in or about August 2007.

Because employee retention is one of the objectives of the Companys bonus programs and
agreements, you must be employed on June 29, 2007 to receive the Guaranteed Bonus and you must be employed on the last day of each fiscal year thereafter to be eligible to receive a bonus for the preceding fiscal year.



|3. | Equity.
|-- | -------

a. It will be recommended to the Board
that you be granted an option to purchase shares of Silicon Graphics, Inc. common stock (the Option). The per share exercise price of the Option will be equal to the fair market value of the common stock on April 16, 2007. The
number of shares will be based on the following formula: (a) if the fair market value of the Companys common stock on the day of the grant (Exercise Price) is less than or equal to $22.50, then the number of shares subject to
the Option will equal 287,500; (b) if the Exercise Price is greater than or equal to $30.00, then the number shares subject to the Option will equal 241,142; (c) if the Exercise Price is greater than $22.50 and less than $30.00, then the
number shares subject to the Option will equal 287,500 less ((the Exercise Price less $22.50) multiplied by 185,434) divided by the Exercise Price. The Option will be granted to you under the Companys Management Incentive Plan (the
MIP); provided, however, that any shares subject to the Option in excess of 147,500 will be subject to stockholder approval of an increase in the maximum number of shares of Common Stock available under the MIP within 9 months following
the option grant date so as to cover those shares. The Option will be evidenced by a standard stock option agreement and will be subject to the terms and conditions of that agreement and the stock option plan under which the Option is granted. The
Option shares shall vest in forty-eight (48) equal monthly installments beginning on the one month anniversary of your employment commencement date, provided you continue in the Companys employment through such date, so that this award
shall be fully vested 48 months after the date of grant. Notwithstanding the foregoing, the Option will not be exercisable until an amendment to the MIP authorizing a change in the vesting provisions of options granted pursuant to the MIP is
approved by the stockholders. The Option shall be a non-statutory stock option under the federal tax laws.

---

b. Depending on the Exercise Price, it will be recommended to the Board that you be granted Restricted
Stocks Units (RSUs), following the commencement of your employment with the Company. The RSUs will be granted to you from shares outside of the MIP. The number of RSUs will be equal to 287,500 less the number of shares of the
Companys Common Stock subject to the Option. The RSUs will be evidenced by an RSU agreement and will be subject to the terms and conditions of that agreement and the plan under which the RSUs are granted, if any. The RSUs shall vest in
forty-eight (48) equal, monthly installments beginning on the one month anniversary of your employment commencement date, provided you continue in the Companys employment through such date  so that this award shall be fully vested
48 months after the date of grant. The shares that vest each calendar year pursuant to the RSU award will be issued to you on or before December 31 of the calendar year in which such shares vest.

c. At any time or from time to time during your employment, following the twenty fourth (24th) month after your employment with the Company
commences, the Compensation Committee may review your equity compensation. As a result of any such review, the Compensation Committee may issue you additional equity grants in their sole discretion.



|4. | Employee Benefits.
|-- | ------------------

a. General Benefits. You
will be eligible to participate in all of the employee benefits and benefit plans that the Company generally makes available to its full-time employees and key executives of the Company, subject to the terms and conditions of such benefits and
benefit plans and subject to any statutory requirements or limitations. These benefits currently include, but are not limited to, stock option plans, stock purchase plans, incentive or other bonus plans, and insurance plans (life, disability,
health, and accident).

b. Vacation. Initially, you will be eligible for three weeks of paid vacation in the first year, and
vacation will accrue thereafter in accordance with the Companys standard vacation accrual policy.



|5. | Expense Reimbursement.
|-- | ----------------------

The Company shall reimburse you for
reasonable and customary business expenses incurred during your employment in accordance with the Companys reimbursement policies in effect from time to time, provided that you furnish to the Company reasonably adequate records and documentary
evidence of such expenses.

The Company shall reimburse you in an amount up to $75,000 of relocation expenses pursuant to the Companys standard
Domestic Relocation Policy, a copy of which is attached hereto.

|-- | -------------------------

(the Release Agreement) that becomes effective and enforceable and (ii) your continued compliance with the Companys standard employee invention assignment and confidentiality agreement. In addition to a release of all claims,

|-- | ------------------

In the event of a Change in
Control as defined below and subject to Section 11 below:

a. provided shareholder approval of the increase to the maximum number of
shares of common stock available under the MIP has been obtained prior to the effective date of a Change in Control, and in any event to the extent of all Option shares that could be validly issued to you, all of the Option shares shall become fully
vested and exercisable immediately prior to the effective time of the Change in Control and you shall have the right to elect during the period beginning immediately prior to such Change in Control and ending on the date that is six months following
the effective date of such Change in Control to either (i) have such Option cashed out at its intrinsic value determined as provided herein or (ii) to exercise such Option. Any cash out proceeds shall be paid to you as soon as
practicable following the date of your election to have such Option cashed out. For this purpose, the intrinsic value of the Option shall be measured as the difference between the aggregate option exercise price of the shares of common stock subject
to the Option (if exercised after the effective time of the Change in Control, as such exercise price is adjusted to reflect the exchange ratio in effect pursuant to the Change in Control transaction) and the fair market value of the surviving
entitys common stock on the date of exercise.

b. the RSUs granted to you by the Company pursuant to this Agreement, shall become
fully vested upon the effective date of a Change in Control, and the shares of common stock subject to such RSUs shall be issued to you within fifteen (15) days following the effective date of such Change in Control.
