 EMPLOYMENT AGREEMENT 
  

THIS EMPLOYMENT AGREEMENT (this “Agreement”) is made and entered into as of December 23, 2002, between Rackable Systems, Inc., a
Delaware corporation (formerly known as Rackable Corporation) (the “Company”) and Tom Barton (“Executive”). 
  
 In consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties intending to be legally bound agree as follows: 
  
 1. Employment. The Company shall employ Executive, and Executive hereby accepts employment with the Company, upon the terms and conditions set forth in this Agreement for the period beginning on the date hereof
and ending on the earlier of (i) the five (5) year anniversary of the date hereof (unless extended by mutual agreement of the parties) or (ii) as provided in Section 4 hereof (the “Employment Period”). 
  
 2. Position and Duties. 
  
 (a) During the Employment Period, Executive shall serve as President and
Chief Executive Officer of the Company, or in such other senior executive position as the Company’s Board of Directors (the “Board”), in its sole discretion, may designate from time to time, subject in each such case, to the
overall direction and authority of the Board. In addition, and without further compensation, Executive shall serve as a director and/or senior executive officer of one or more of the Company’s Affiliates if requested by the Board and so elected
or appointed. 
  
 (b) During the Employment Period, Executive
shall report to the Board or its designee, and Executive shall devote his best efforts and his full business time, business judgment, skill, knowledge and attention to advancing the business and affairs of the Company and its Affiliates as the Board
or its designee may from time to time direct and to the discharge of his duties and responsibilities hereunder, with the understanding that Executive will also devote a certain amount of time and attention to personal investment activities, and
civic, charitable or religious activities (but excluding employment with any business other than the Company) so long as such activities do not interfere with Executive’s performance of his duties hereunder. 
  
 3. Base Salary and Benefits. 
  
 (a) During the Employment Period, Executive’s base salary shall be
$180,000 per year (the “Base Salary”), which salary shall be payable in regular installments in accordance with the Company’s general payroll practices and shall be subject to required withholding. The Base Salary shall be
reviewed by the Board for increase at least once every twelve (12) months. 
  
 (b) Executive will be eligible to receive an annual bonus (the “Bonus”) of $60,000, based upon Executive and the Company meeting targets (including revenue and profitability targets and other
organizational milestones) set by the Board and agreed upon in writing by the Executive (i) which shall be consistent with Exhibit A attached hereto for fiscal year 2003 and (ii) which shall be determined by the Board and Executive annually
thereafter. The Bonus (if any) shall be payable quarterly for fiscal year 2003 and annually thereafter. 
  
 (c) Executive shall be eligible to be included in all employee benefit plans, programs or arrangements (including, without limitation, any plans, programs
or arrangements providing for retirement benefits, incentive compensation, profit sharing, bonuses, disability benefits, health and life insurance, automobile (or automobile allowance), vacation and paid holidays) to the extent established by the
Company for, or made available to all its senior executives. 
  

 1. 








 (d) The Company shall reimburse Executive for all reasonable out-of-pocket expenses incurred by him in
the course of performing his duties under this Agreement which are consistent with the Company’s policies in effect from time to time with respect to travel, entertainment and other business expenses, subject to the Company’s requirements
with respect to reporting and documentation of such expenses. 
  
 (e) The Company shall grant Executive two stock options, subject to the terms and conditions of the Company’s 2002 Stock Option Plan and the Option Agreements (in forms and substance as attached hereto as Exhibit B) (the
“Stock Option Agreements”) executed by Executive and the Company as a condition to the grant of such options. 
  
 (f) Without the prior written consent of Executive, the Company will not adopt any changes or amendments to its charter and bylaws provisions reducing the
level of indemnification provided to its officers and directors. The Company intends to obtain Directors and Officers’ insurance (“D&O Insurance”) as soon as practicable and Executive will be covered under such D&O
Insurance and other applicable insurance policies. 
  
 4.
Term. 
  
 (a) The Employment Period shall begin on the
date hereof and shall terminate upon the earlier of (i) the five (5) year anniversary of the date hereof (unless extended by the mutual agreement of the parties), (ii) Executive’s resignation without Good Reason, death or Disability, (iii) the
termination by the Company at any time without Cause or by Executive with Good Reason, and (iv) the termination by the Company at any time with Cause. 
  
 (b) If the Employment Period is terminated by the Company without Cause or by Executive for Good Reason, the Company shall provide, and the Executive
shall be entitled to receive the following: (i) his Base Salary payable in regular installments from the date of termination through the date that is six (6) months after the date of termination; and (ii) payment of COBRA premiums for the Executive
and his covered dependents for a period of six (6) months after the end of the Employment Period (collectively, the “Severance Benefits”). Any such amounts payable under this Section 4(b) will be payable at such times as such
amounts would have been payable had Executive not been terminated. In addition, in accordance with the Stock Option Agreement, in the event the Employment Period is terminated by the Company without Cause or by Executive for Good Reason prior to the
one year anniversary of the date hereof, Executive’s stock options issued thereunder shall be deemed 20% vested. Notwithstanding anything in this Agreement to the contrary, the Company shall have no obligation to pay any amounts, or provide any
benefits, payable under this Section 4(b) in the event that Executive has, directly or indirectly, taken any action described in Sections 6 or 7 hereof. As a condition to the Company’s obligations (if any) to make severance
payments, and provide benefits, pursuant to this Section 4(b), Executive and the Company will execute and deliver a general release for the benefit of the Company in form and substance mutually satisfactory to the Company and Executive, each
of the parties acting in good faith. 
  
 (c) If the Employment
Period ends for any other reason than termination by the Company without Cause or by Executive’s resignation without Good Reason, Executive shall be only entitled to receive his Base Salary through the date of termination. 
  

 2. 








 (d) Except as otherwise provided above, all of Executive’s rights to unvested or unearned benefits
and compensation (including, without limitation, bonuses) hereunder (if any) which accrue or become payable after the termination of the Employment Period shall cease upon such termination. 
  
 5. Parachute Payments. If any payment or benefit Executive would
receive from the Company in connection with a change in control of the beneficial ownership of the Company or otherwise (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the
Internal Revenue Code of 1986, as amended (the “Code”), and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the
Reduced Amount. The “Reduced Amount” shall be either (x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of
the Payment, whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Executive’s receipt, on an
after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that
the Payment equals the Reduced Amount, reduction shall occur in the following order unless Executive elects in writing a different order (provided, however, that such election shall be subject to Company approval if made on or after the date on
which the event that triggers the Payment occurs): reduction of cash payments; cancellation of accelerated vesting of stock awards; reduction of employee benefits. In the event that acceleration of vesting of stock award compensation is to be
reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of Executive’s stock awards unless Executive elects in writing a different order for cancellation. 
  
 In addition, at the reasonable request of Executive, the Company shall use
its best efforts to submit to the stockholders of the Company for approval the amount of Executive’s Payment pursuant to the requirements of Section 280(G) of the Code. 
  
 6. Confidential Information, Inventions and Intellectual Property Rights; Non-Disparagement; Confidentiality of
Terms. 
  
 (a) Executive hereby acknowledges and reaffirms
all of his liabilities and obligations under that certain Invention and Non-Disclosure Agreement, dated as of the date hereof, by and between the Company and Executive and attached hereto as Exhibit B. 
  
 (b) Executive agrees that Executive shall not, at any time, whether during or
after Executive ceases to provide services to the Company or any of its Affiliates, make or publish any untruthful statement (orally or in writing) that intentionally libels, slanders, disparages or otherwise defaces the goodwill or reputation
(whether or not such disparagement legally constitutes libel or slander) of the Company, any Subsidiary, RSI or any of their Affiliates, or its other officers, managers, directors, partners or investment professionals. 
  
 (c) The Company agrees that it shall direct its senior officers to not, at
any time, whether during or after Executive ceases to provide services to the Company or any of its Affiliates, make or publish any untruthful statement (orally or in writing) that intentionally libels, slanders, disparages or otherwise defaces the
goodwill or reputation (whether or not such disparagement legally constitutes libel or slander) of the Executive. 
  
 (d) Executive agrees, subject to applicable law, to treat with confidentiality the terms of this Agreement and to not disclose or discuss or release any
such terms to any person or entity (except Executive’s attorneys, accountants and other consultants and Executive’s spouse who agree to keep such information confidential) without the consent of the Board. 
  

 3. 








 7. Non-Solicitation. 
  
 (a) In further consideration of the compensation to be paid to Executive hereunder, Executive acknowledges that in the
course of his employment with the Company or any of its Affiliates he shall become familiar and during his employment with the Company and RSI prior to the date hereof he has become familiar with RSI’s and the Company’s trade secrets and
with other Confidential Information and Work Product concerning the Company, its Affiliates and RSI, including, without limitation, Confidential Information and Work Product and that his services have been and shall be of special, unique and
extraordinary value to the Company, its Affiliates and RSI. Therefore, Executive agrees that during the period beginning on the date hereof and ending on the two (2) year anniversary of the termination of the Employment Period (the
“Non-solicitation Period”), he shall not directly or indirectly through another entity (i) induce or attempt to induce any employee of the Company (or any of its Subsidiaries or any of its other Affiliates to which Executive
provides executive services (each Subsidiary and Affiliate, together with RSI, a “Designated Affiliate”) to leave the employ of the Company or such Designated Affiliate; (ii) hire or employ any person who was an employee of the
Company or any Designated Affiliate at any time during the Employment Period; (iii) call on, solicit, or service any customer, supplier, licensee, licensor or other business relation or prospective client of the Company or any Designated Affiliate
with respect to products and/or services that are or have been provided by the Company or such Designated Affiliate during the twelve-month period prior to the termination of the Employment Period, or which the Company or its Designated Affiliate is
currently in the process of developing; or (iv) induce or attempt to induce any customer, supplier, licensee, licensor or other business relation of the Company or any of its Designated Affiliates to cease doing business with the Company or such
Designated Affiliate. For the purposes of this Agreement, “RSI” shall mean Rackable Systems, Inc. and its predecessors, the predecessor in interest to the Company’s business. 
  
 (b) Executive acknowledges that, in the course of his employment with the
Company and RSI, he has and will become familiar with the Confidential Information and Work Product of the Company and its Designated Affiliates. Executive further acknowledges that the scope of the business of the Company and its Designated
Affiliates is independent of location (such that it is not practical to limit the restrictions contained in this Section 7 to a specified county, city, or part thereof) and that, therefore, as a senior executive of the Company or one of its
Designated Affiliates, Executive has and will have direct or indirect responsibility, oversight or duties with respect to all of the businesses of the Company and its Designated Affiliates and its and their current and prospective employees,
vendors, customers, clients and other business relations, and that, accordingly, the restrictions contained in this Section 7 are reasonable in all respects and necessary to protect the goodwill and Confidential Information and Work Product
of the Company and its Designated Affiliates and that, without such protection, the Company’s and its Designated Affiliates’ customer and client relations and competitive advantage would be materially adversely effected. It is specifically
recognized by Executive that his services to the Company and its Designated Affiliates are special, unique, and of extraordinary value, that the Company and its Subsidiaries have a protectable interest in prohibiting Executive as provided in this
Section 7, that Executive is significantly responsible for the growth and development of the Company and its Designated Affiliates and the creation and preservation of their goodwill, and that money damages are insufficient to protect such
interests, that such prohibitions would be necessary and appropriate without regard to payments being made to Executive hereunder, and that the Company would not enter this Agreement with Executive without the restrictions contained in this
Section 7. Executive further acknowledges that the restrictions contained in this Section 7 do not impose an undue hardship on him. Executive agrees that each provision of this Section 7 shall be interpreted in such manner as to
be effective and valid under applicable law, but if any provision of this Section 7 is held to be invalid, illegal or unenforceable in any 
  

 4. 








 respect under any applicable law by which this Agreement is governed, such invalidity, illegality or unenforceability
shall not affect any other provision of this Section 7; provided that such provision shall be construed to give effect to the parties intent of such provision to the maximum extent permitted by applicable law. 
  
 8. Enforcement. If, at the time of enforcement of Section 6 or
7 of this Agreement, a court holds that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographical area reasonable under such circumstances shall
be substituted for the stated period, scope or area. Because Executive’s services are unique and because Executive has access to Confidential Information and Work Product, and for the other reasons set forth herein, the parties hereto agree
that money damages would not be an adequate remedy for any breach of this Agreement. Therefore, in the event a breach or threatened breach of any of Section 6 or 7 of this Agreement that is continuing, the Company, its successors or
assigns and any third-party beneficiary to this Agreement may, in addition to other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive or other relief in order to
enforce, or prevent any violations of, the provisions hereof (without posting a bond or other security). In addition, in the event of a breach or violation by Executive of Section 7, the Non-Solicitation Period shall be tolled until such
breach or violation has been duly cured. Executive agrees that the restrictions contained in this Section 8 are reasonable. Except as provided by applicable law, the enforceability and scope of this Agreement shall not be limited on the
ground that the termination of Executive’s employment was initiated by the Company. 
  
 9. Other Businesses. Except as expressly provided for herein, as long as Executive is employed by the Company or any of its Subsidiaries, Executive agrees that he will not, except with the express written
consent of the Board, become engaged in, or render services for, any business other than the business of the Company, any of its Affiliates or any corporation, partnership or other Person in which the Company or any of its Affiliates has an equity
interest; provided that this Section 9 shall not restrict Executive’s ability to devote a certain amount of time and attention to personal investment activities, and civic, charitable or religious activities in accordance with Section
2(b) above (but excluding employment with, or service to, any business other than the Company). 
  
 10. Executive’s Representations. Executive hereby represents and warrants to the Company that (i) the execution, delivery and performance of
this Agreement by Executive do not and shall not conflict with, breach, violate or cause a default under any contract, agreement, instrument, order, judgment or decree to which Executive is a party or by which he is bound, (ii) Executive is not a
party to or bound by any employment agreement or noncompete agreement, or any confidentiality agreement inconsistent with this Agreement, and (iii) upon the execution and delivery of this Agreement by the Company, this Agreement shall be the valid
and binding obligation of Executive, enforceable in accordance with its terms. Executive hereby acknowledges and represents that he has consulted with independent legal counsel regarding his rights and obligations under this Agreement and that he
fully understands the terms and conditions contained herein.

limitation. Reference to any agreement, document or instrument means such agreement, document or instrument as amended or otherwise modified from time to time in accordance with the terms thereof, and if applicable hereof. Without limiting the
generality of the immediately preceding sentence, no amendment or other modification to any agreement, document or instrument that requires the consent of any Person pursuant to the terms of this Agreement or any other agreement will be given effect
hereunder unless such Person has consented in writing to such amendment or modification. The use of the words “or,” “either” and “any” shall not be exclusive.

 22. Choice of Law. All issues and questions concerning the construction, validity, enforcement and interpretation of this Agreement and the
exhibits and schedules hereto shall be governed by, and construed in accordance with, the laws of the state of California, without giving effect to any choice of law or conflict of law rules or provisions (whether of the state of California or any
other jurisdiction) that would cause the application of the laws of any jurisdiction other than the state of California. 
  
 23. Amendment and Waiver. The provisions of this Agreement may be amended or waived only with the prior written consent of the Company (with Board
approval) and Executive, and no course of conduct or failure or delay in enforcing the provisions of this Agreement shall affect the validity, binding effect or enforceability of this Agreement. 
  
 24. Delivery by Facsimile. This Agreement, the agreements referred to
herein, and each other agreement or instrument entered into in connection herewith or therewith or contemplated hereby or 
  

 8. 








 thereby, and any amendments hereto or thereto, to the extent signed and delivered by means of a facsimile machine, shall
be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto or
to any such agreement or instrument, each other party hereto or thereto shall re-execute original forms thereof and deliver them to all other parties. No party hereto or to an such agreement or instrument shall raise the use of a facsimile machine
to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine as a defense to the formation or enforceability of a contract and each such party forever waives
any such defense. 
  
 25. Dispute Resolution. Other than
with respect to suits for injunctive or other equitable relief, any dispute under this Agreement shall be resolved by instituting, after thirty (30) days written notice to the other party, an arbitration to be conducted in San Francisco, California

such arbitration shall be conducted by a panel of three arbitrators, one of whom is selected by the Company, one of whom is selected by the Executive and one of whom is mutually agreeable to the arbitrators selected by the Company and Executive;
provided that such arbitrators shall each be a retired judge or other qualified person with relevant experience in deciding cases concerning the matter which is the subject of the dispute. The arbitrators shall prepare a written decision containing
the essential findings and conclusions on which the award is based so as to ensure meaningful judicial review of the decision. In rendering such decision, the arbitrators shall not add to, subtract from or otherwise modify the provisions of this
Agreement and shall make their determinations in accordance therewith. Any award rendered by the arbitrators shall be final, binding and sole and exclusive with respect to the subject matter thereof and judgment may be entered on it in any court of
competent jurisdiction. The losing party shall pay the fees and expenses of both parties and the arbitrators, and the arbitrators shall resolve any fee disputes. Notwithstanding the provisions of this Section 25, nothing herein shall be
construed in such a manner as to prevent the Company from terminating Executive in accordance with the terms of this Agreement.

Executives completing the 100 Day Plan, $15,000 will be earned for exceeding $63MM of Revenue and $7.5MM of EBITDA, and $7,500 will be earned for exceeding the hurdle on the second metric. The calculation of the $7,500 is based on the Executives
achieving 25% of the EBITDA hurdle [(8.0-7.5) / (9.5-7.5)] as it was lower than the 28.6% achievement of the Revenue hurdle [(65-63) / (70-63)].

Option Shares within 90 days after the Repurchase Event. The Company may elect to purchase all or any portion of the Option Shares. The Repurchase Notice will set forth the number of Option Shares to be acquired from such holder(s), the aggregate
consideration to be paid for such holder’s Option Shares and the time and place for the closing of the transaction. If any Option Shares are held by any transferees of Executive, the Company will purchase such Option Shares elected to be

 5. 








 (d) Parthenon Repurchase. If for any reason the Company does not elect to purchase all of the
Option Shares pursuant to the Repurchase Option. Parthenon shall be entitled to exercise the Repurchase Option for all or any portion of the Option Shares that the Company has not elected to purchase (the “Available Shares”). As
soon as practicable after the Company has determined that there will be Available Shares, but not later than 90 days following the Repurchase Event, the Company shall give written notice (the “Option Notice”) to Parthenon and
Executive setting forth the number of Available Shares and the purchase price for the Available Shares. Parthenon may elect to purchase any or all of the Available Shares by giving written notice to the Company and Executive within one month after

purchase, the aggregate purchase price and the time and place of the closing of the transaction.

and Supplemental Repurchase Notice, as the case may be. The Company will pay for any Option Shares to be purchased pursuant to a Repurchase Option by first offsetting any amounts outstanding under any bona fide debts owed by Executive (or one or

certified or cashier’s check or wire transfer of funds in the aggregate amount of the purchase price for such Option Shares. Parthenon will pay for Option Shares to be purchased by it pursuant to the Repurchase Option by first offsetting

its Affiliates and will pay the remainder of the purchase price by a certified or cashier’s check or wire transfer of funds in the aggregate amount of the purchase price for such Option Shares. Executive acknowledges that all repurchases of
Option Shares will be subject to applicable restrictions and covenants contained in applicable law and in the Company’s and its affiliates financing agreements. Notwithstanding anything to the contrary contained herein, if (A) any such
restrictions or covenants contained in such financing agreements or applicable law prohibit the repurchase by cash of Option Shares hereunder which the Company is otherwise entitled to make, or such repurchase for cash would result in a default or
acceleration under such financing agreements, or (B) the Company does not have adequate cash availability (as determined in its sole discretion) (collectively, the “Repurchasing Circumstances”), then the Company will not be required
to make such repurchase (and may defer making such repurchase even though it has exercised the Repurchase Option) until promptly following the date that the Repurchasing Circumstances cease to exist or until the completion of the nine month period
following the Repurchase Event, whichever is earlier. 
  
 9.
Restrictions on Transfer of Option Shares. 
  
 (a)
Non-Transferability of Option. The Option is personal to Executive and is not transferable by Executive other than by will or the laws of descent and distribution. During such Executive’s lifetime only Executive (or his guardian or legal
representative) may exercise the Option. In the event of such Executive’s death, the Option may be exercised only (i) by the executor or administrator of Executive’s estate or the person or persons to whom Executive’s rights under the
Option shall pass by will or the laws of descent and distribution and (ii) to the extent that Executive was entitled hereunder at the date of such Executive’s death. 
  

 6. 








 (b) Transfer of Option Shares. Executive shall not sell, pledge, transfer or otherwise dispose (a
“Transfer”) any interest in any Option Shares unless Executive obtains the prior written consent of the Board. 
  
 10. Additional Restrictions on Transfer. 
  
 (a) Legend. The certificates, if any, representing the Option Shares will bear the following legend: 
  
 “THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION THEREUNDER. THE SECURITIES
REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER, CERTAIN REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH IN AN OPTION AGREEMENT BETWEEN THE COMPANY AND TOM BARTON DATED DECEMBER
    , 2002 PURSUANT TO WHICH THEY WERE ORIGINALLY ISSUED, A COPY OF WHICH MAY BE OBTAINED BY THE HOLDER HEREOF AT THE ISSUER’S PRINCIPAL PLACE OF BUSINESS WITHOUT CHARGE.” 
  
 The legend set forth above shall be removed from the certificates evidencing
any securities which cease to be Option Shares. 
  
 (b)
Transfer Requirement. No holder of Option Shares may Transfer any Option Shares (except pursuant to an effective registration statement under the Securities Act) without first delivering to the Company an opinion of counsel reasonably
acceptable in form and substance to the Company (which counsel will be reasonably acceptable to the Company) that registration under the Securities Act is not required in connection with such Transfer and that such Transfer is in compliance with the
provisions herein. If such opinion of counsel reasonably acceptable in form and substance to the Company further states that no subsequent Transfer of such Option Shares will require registration under the Securities Act, the Company will promptly
upon such Transfer deliver new certificates (in the event such Option Shares are certificated) for such securities which do not bear the Securities Act legend set forth in Section 10(a). 
  
 (c) Securities Laws Restrictions and Other Restrictions on Transfer of
Option Shares. Executive hereby represents that when such Executive exercises his Option Executive shall be purchasing Option Shares for his own account and not on behalf of others. Executive understands and acknowledges that federal and state
securities laws govern and restrict such Executive’s right to Transfer any Option Shares unless such Transfer thereof is registered under the Securities Act and state securities laws, or in the opinion of the Company’s counsel, such offer,
sale or other disposition is exempt from registration or qualification thereunder. Subject to the terms and conditions set forth in this Agreement, Executive hereby agrees that he shall not Transfer any Option Shares in any manner which would: (i)
require the Company to file any registration statement with the Securities and Exchange Commission (or any similar filing under state law) or to amend or supplement any such filing or (ii) violate or cause the Company to violate the Securities Act,
the rules and regulations promulgated thereunder or any other state or federal law. 
  

 7. 








 11. Approved Sale. 
  
 (a) In the event of an Approved Sale (as defined below), each holder of Option Shares will vote for, consent to and raise no
objections against such Approved Sale, provided that such holders participating in such Approved Sale will, upon the consummation of such Approved Sale, be entitled to receive the same type of consideration as to be received by the preferred
stockholders of the Company and provided further that, if there is more than one type of consideration, that each type of consideration be allocated proportionately among the preferred stockholders of the Company and such holders based upon the
total value of consideration to be received by the preferred stockholders and such holders in the transaction. Lithe Approved Sale is structured (x) as a merger or consolidation, each such holder of Option Shares will waive any dissenters rights,
appraisal rights or similar rights in conjunction with such merger or consolidation or (y) as a sale of equity, each such holder of Option Shares will agree to sell up to all of such Option Shares on the terms and conditions approved by the Company,
and (z) as a sale of assets, each such holder of Option Shares will vote in favor of any subsequent liquidation or other distribution of the proceeds therefrom as approved by the Board. Each holder of Option Shares will take all necessary or
desirable actions in connection with the consummation of the Approved Sale as requested by Parthenon (including, without limitation, by executing and delivering definitive agreements with respect thereto). An “Approved Sale” means
any transaction approved by Parthenon or the Board involving a sale of over 50% of the assets of the Company or any direct Subsidiary thereof or of equity with over 50% of the voting power of the Company or of any direct Subsidiary thereof (whether
by merger, consolidation, recapitalization, transfer of equity securities or otherwise), or any such transaction involving any other Subsidiary. 
  
 (b) Upon the consummation of the Approved Sale, each holder of Option Shares participating in such Approved Sale will receive the same portion of the
aggregate consideration available to be distributed to the common stockholders of the Company (in their capacity as such) that such holders participating in such sale (in their capacity as stockholders of the Company) would have received if such
aggregate consideration had been distributed by the Company in complete liquidation pursuant to the rights and preferences set forth in the Company’s Certificate of Incorporation as in effect immediately before such Approved Sale (a
“Liquidation”) (and, in the event of a sale of stock, assuming that the only securities of the Company outstanding were those shares of capital stock involved in such sale), and assuming that the holders of convertible securities
had converted their shares if by converting such holders would have received more proceeds upon a Liquidation (for the purposes of clarity, any holders of options or warrants shall only be entitled to receive proceeds in respect thereof if such
options or warrants are exercised in connection with such Approved Sale). 
  
 (c) Each holder of Option Shares will be obligated to join on a pro rata basis (applied such that after giving effect thereto, the aggregate consideration paid to each such holder would comply with the provisions of
Section 10(b)) in any purchase price adjustments, indemnification or other obligations that the sellers of Option Shares are required to provide in connection with the Approved Sale (other than any such obligations that relate solely to a
particular holder of Option Shares, such as indemnification with respect to representations and warranties given by a holder regarding such holder’s title to and ownership of Option Shares, in respect of which only such holder will be liable)
(and, without limiting the foregoing, in the Company’s sole discretion, the proceeds with respect to an Approved Sale may be withheld from any holder pending the execution of such documents or posting of security as the Board deems necessary to
cover any purchase price adjustments, indemnification or other such obligations of the Company or such holder). 
  
 (d) If the Company or the holders of the Company’s securities enter into any negotiation or transaction for which Rule 506 (or any similar rule then
in effect) promulgated by the Securities and Exchange Commission may be available with respect to such negotiation or transaction (including a 

  

 8. 








 
merger, consolidation or other reorganization), the holders of Option Shares will, at the request of the Company, appoint a purchaser representative (as such
term is defined in Rule 501) reasonably acceptable to the Company. If any holder of Option Shares appoints a purchaser representative designated by the Company, the Company will pay the fees of such purchaser representative, but if any holder of
Option Shares declines to appoint the purchaser representative designated by the Company, such holder will appoint another purchaser representative, and such holder will be responsible for the fees of the purchaser representative so appointed.

  
 (e) Each holder of Option Shares will bear their pro rata
share (applied such that after giving effect thereto, the aggregate consideration paid to each such holder would comply with the provisions of Section 10(b)) of the costs of any sale of such Option Shares pursuant to an Approved Sale to the
extent such costs are incurred for the benefit of all holders of Option Shares participating in such Approved Sale and are not otherwise paid by the Company or the acquiring party. Costs incurred by the holders of Option Shares on their own behalf
will not be considered costs of the transaction hereunder; it being understood that the fees and disbursements of one counsel chosen by Parthenon will be deemed for the benefit of all holders of Option Shares participating in such Approved Sale.

  
 (f) If any holder of Option Shares fails to deliver any
certificates representing its Option Shares as required by this Section 10, such holder (i) will not be entitled to the consideration that such holder would otherwise receive in the Approved Sale until such holder cures such failure by
providing the Company with reasonably satisfactory evidence (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing his or its Option Shares, and
indemnify in respect thereto which is reasonably satisfactory to the Company (provided that, after curing such failure, such holder will be so entitled to such consideration without interest), (ii) will be deemed, for all purposes, no longer
to be a stockholder of the Company and will have no voting rights, (iii) will not be entitled to any dividends or other distributions declared after the Approved Sale with respect to the Option Shares held by such holder, (iv) will have no other
rights or privileges granted to the holder of Option Shares under this or any future agreement, and (v) in the event of liquidation of the Company, such holder’s rights with respect to any consideration that such holder would have received if
such holder had complied with this Section 11 if any, will be subordinate to the rights of any equity holder. 
  
 (g) The provisions of this Section 11 shall terminate upon a Public Offering. 
  
 12. Holdback Agreement. Before and after the effective date of any underwritten Public Offering, no holder of Option
Shares will effect any sale or distribution of Option Shares during the period designated by the underwriters managing such underwritten Public Offering. 
  
 13. Conformity with 2002 Plan. The Option granted hereunder is intended to conform in all respects with, and is subject to all applicable
provisions of, the 2002 Plan (which is incorporated herein by reference). Inconsistencies between this Agreement and the 2002 Plan shall be resolved in accordance with the terms of the 2002 Plan. By executing and returning the enclosed copy of this
Agreement, Executive acknowledges his receipt of this Agreement and the 2002 Plan and agree to be bound by all of the terms of this Agreement and the 2002 Plan. 
  

14. Rights of Participants. Nothing in this Agreement shall interfere with or limit in any way the right of the Company to terminate
Executive’s employment at any time (with or without Cause), nor confer upon Executive any right to continue in the employ of the Company for any period of time or to continue Executive’s present (or any other) rate of compensation, and in
the event of Executive’s termination of employment (including, but not limited to, termination by the Company without Cause) any portion of the Option that was not previously vested and exercisable shall be forfeited. Nothing in

Designated Affiliate during the twelve-month period prior to the Termination Date, or which the Company or its Designated Affiliate is currently in the process of developing; or (D) induces or attempts to induce any customer, supplier, licensee,
licensor or other business relation of the Company or any of its Designated Affiliates to cease doing business with the Company or such Designated Affiliate. Notwithstanding the foregoing, a Repurchase Event will not occur if Todd Ford and Tom
Barton elect to work together following their termination of employment with the Company, and do not otherwise take any of the actions described in this Section 7(b)(i), and provided further that such collaboration is not a Repurchase Event under
Sections 7(b)(ii) or 7(b)(iii) below. For the purposes of this Agreement, “RSI” shall mean Rackable Systems, Inc. and its predecessors, the predecessor in interest to the Company’s business. 
  
 (ii) If at any time from the effective date of the
Employment Agreement through the two (2) year anniversary of the Termination Date, Executive intentionally uses, discloses or misappropriates the intellectual property or other confidential information of the Company and such use, disclosure or
misappropriation causes material harm to the Company. 
  
 (iii) If at any time from the Termination Date through the two (2) year anniversary of the Termination Date, Executive provides services to any person entity that provides substantially similar services and/or products as the Company on the
Termination Date of during the twelve-month period prior to the Termination Date. 
  
 (iv) Nothing contained in this Option Agreement shall affect any of the Company’s rights or the Executive’s obligations under
his employment agreement with the Company or any other agreements related thereto. 
  
 (c) Repurchase Procedures. The Company may elect or decline to exercise the Repurchase Option by delivering written notice (the
“Repurchase Notice”) to the holder or holders of the applicable Option Shares within 90 days after the Repurchase Event. The Company may elect to purchase all or any portion of the Option Shares. The Repurchase Notice will set forth
the number of Option Shares to be acquired from such holder(s), the aggregate consideration to be paid for such holder’s Option Shares and the time and place for the closing of the transaction. If any Option Shares are held by any transferees
of Executive, the Company will purchase such Option Shares elected to be purchased from such holder(s), pro rata according to the number of Option Shares held by such holder(s) at the time of delivery of the Repurchase Notice (determined as nearly
as practicable to the nearest share of Option Shares). 
  
 (d) Parthenon Repurchase. If for any reason the Company does not elect to purchase all of the Option Shares pursuant to the Repurchase Option, Parthenon shall be entitled to exercise the Repurchase Option for all or any portion of
the Option Shares that the Company has not elected to purchase (the “Available Shares”). As soon as practicable after the Company has determined that there will be Available Shares, but not later than 90 days following the
Repurchase Event, the Company shall give written notice (the “Option Notice”) to Parthenon and Executive setting forth the number of Available Shares and the purchase price for the Available Shares. Parthenon may elect to purchase
any or all of the Available Shares by giving written 

  

 6. 








 
notice to the Company and Executive within one month after the Option Notice has been given by the Company. As soon as practicable thereafter, the Company
shall notify each holder of Option Shares as to the number of shares being purchased from such holder by Parthenon (the “Supplemental Repurchase Notice”). At the time the Company delivers the Supplemental Repurchase Notice to the
holder(s) of Option Shares, the Company shall also deliver written notice to Parthenon setting forth the number of shares Parthenon is entitled to purchase, the aggregate purchase price and the time and place of the closing of the transaction.

  
 8. Closing of Repurchase. The closing of a repurchase
transaction will take place on the date(s) designated by the Company in the Repurchase Notice and Supplemental Repurchase Notice, as the case may be. The Company will pay for any Option Shares to be purchased pursuant to a Repurchase Option by first
offsetting any amounts outstanding under any bona fide debts owed by Executive (or one or more of Executive’s transferees, other than the Company, Parthenon, or a bona fida purchaser following a Public Offering or a Sale of the Company) to the
Company or any of its Affiliates and will pay the remainder of the purchase price by a certified or cashier’s check or wire transfer of funds in the aggregate amount of the purchase price for such Option Shares. Parthenon will pay for Option
Shares to be purchased by it pursuant to the Repurchase Option by first offsetting amounts outstanding under any bona fide debts owed by Executive (or one or more of Executive’s transferees, other than the Company, Parthenon or a bona fida
purchaser following a Public Offering or a Sale of the Company) to Parthenon or any of its Affiliates and will pay the remainder of the purchase price by a certified or cashier’s check or wire transfer of funds in the aggregate amount of the
purchase price for such Option Shares. Executive acknowledges that all repurchases of Option Shares will be subject to applicable restrictions and covenants contained in applicable law and in the Company’s and its affiliates financing
agreements. Notwithstanding anything to the contrary contained herein, if (A) any such restrictions or covenants contained in such financing agreements or applicable law prohibit the repurchase by cash of Option Shares hereunder which the Company is
otherwise entitled to make, or such repurchase for cash would result in a default or acceleration under such financing agreements, or (B) the Company does not have adequate cash availability (as determined in its sole discretion) (collectively, the
“Repurchasing Circumstances”), then the Company will not be required to make such repurchase (and may defer making such repurchase even though it has exercised the Repurchase Option) until promptly following the date that the
Repurchasing Circumstances cease to exist or until the completion of the nine month period following the Repurchase Event, whichever is earlier. 
  
 9. Restrictions on Transfer of Option Shares. 
  
 (a) Non-Transferability of Option. The Option is personal to Executive and is not transferable by Executive other than by will or
the laws of descent and distribution. During such Executive’s lifetime only Executive (or his guardian or legal representative) may exercise the Option. In the event of such Executive’s death, the Option may be exercised only (i) by the
executor or administrator of Executive’s estate or the person or persons to whom Executive’s rights under the Option shall pass by will or the laws of descent and distribution and (ii) to the extent that Executive was entitled hereunder at
the date of such Executive’s death. 
  

 7. 








 (b) Transfer of Option Shares. Executive shall not sell, pledge, transfer or
otherwise dispose (a “Transfer”) any interest in any Option Shares unless Executive obtains the prior written consent of the Board. 
  
 10. Additional Restrictions on Transfer. 
  
 (a) Legend. The certificates, if any, representing the Option Shares will bear the following legend: 
  
 “THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION THEREUNDER. THE SECURITIES
REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER. CERTAIN REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH IN AN OPTION AGREEMENT BETWEEN THE COMPANY AND TOM BARTON DATED DECEMBER
    , 2002 PURSUANT TO WHICH THEY WERE ORIGINALLY ISSUED, A COPY OF WHICH MAY BE OBTAINED BY THE HOLDER HEREOF AT THE ISSUER’S PRINCIPAL PLACE OF BUSINESS WITHOUT CHARGE.” 
  
 The legend set forth above shall be removed from the
certificates evidencing any securities which cease to be Option Shares. 
  
 (b) Transfer Requirement. No holder of Option Shares may Transfer any Option Shares (except pursuant to an effective registration statement under the Securities Act) without first delivering to the Company an
opinion of counsel reasonably acceptable in form and substance to the Company (which counsel will be reasonably acceptable to the Company) that registration under the Securities Act is not required in connection with such Transfer and that such
Transfer is in compliance with the provisions herein. If such opinion of counsel reasonably acceptable in form and substance to the Company further states that no subsequent Transfer of such Option Shares will require registration under the
Securities Act, the Company will promptly upon such Transfer deliver new certificates (in the event such Option Shares are certificated) for such securities which do not bear the Securities Act legend set forth in Section 10(a). 

 
 (c) Securities Laws Restrictions and Other
Restrictions on Transfer of Option Shares. Executive hereby represents that when such Executive exercises his Option Executive shall be purchasing Option Shares for his own account and not on behalf of others. Executive understands and
acknowledges that federal and state securities laws govern and restrict such Executive’s right to Transfer any Option Shares unless such Transfer thereof is registered under the Securities Act and state securities laws, or in the opinion of the
Company’s counsel, such offer, sale or other disposition is exempt from registration or qualification thereunder. Subject to the terms and conditions set forth in this Agreement, Executive hereby agrees that he shall not 

  

 8. 








 
Transfer any Option Shares in any manner which would: (i) require the Company to file any registration statement with the Securities and Exchange Commission
(or any similar filing under state law) or to amend or supplement any such filing or (ii) violate or cause the Company to violate the Securities Act, the rules and regulations promulgated thereunder or any other state or federal law. 
  
 11. Approved Sale. 
  
 (a) In the event of an Approved Sale (as defined below),
each holder of Option Shares will vote for, consent to and raise no objections against such Approved Sale, provided that such holders participating in such Approved Sale will, upon the consummation of such Approved Sale, be entitled to receive the
same type of consideration as to be received by the preferred stockholders of the Company and provided further that, if there is more than one type of consideration, that each type of consideration be allocated proportionately among the preferred
stockholders of the Company and such holders based upon the total value of consideration to be received by the preferred stockholders and such holders in the transaction. If the Approved Sale is structured (x) as a merger or consolidation, each such
holder of Option Shares will waive any dissenters rights, appraisal rights or similar rights in conjunction with such merger or consolidation or (y) as a sale of equity, each such holder of Option Shares will agree to sell up to all of such Option
Shares on the terms and conditions approved by the Company, and (z) as a sale of assets, each such holder of Option Shares will vote in favor of any subsequent liquidation or other distribution of the proceeds therefrom as approved by the Board.
Each holder of Option Shares will take all necessary or desirable actions in connection with the consummation of the Approved Sale as requested by Parthenon (including, without limitation, by executing and delivering definitive agreements with
respect thereto). An “Approved Sale” means any transaction approved by Parthenon or the Board involving a sale of over 50% of the assets of the Company or any direct Subsidiary thereof or of equity with over 50% of the voting power
of the Company or of any direct Subsidiary thereof (whether by merger, consolidation, recapitalization, transfer of equity securities or otherwise), or any such transaction involving any other Subsidiary. 
  
 (b) Upon the consummation of the Approved Sale, each holder
of Option Shares participating in such Approved Sale will receive the same portion of the aggregate consideration available to be distributed to the common stockholders of the Company (in their capacity as such) that such holders participating in
such sale (in their capacity as stockholders of the Company) would have received if such aggregate consideration had been distributed by the Company in complete liquidation pursuant to the rights and preferences set forth in the Company’s
Certificate of Incorporation as in effect immediately before such Approved Sale (a “Liquidation”) (and, in the event of a sale of stock, assuming that the only securities of the Company outstanding were those shares of capital stock
involved in such sale), and assuming that the holders of convertible securities had converted their shares if by converting such holders would have received more proceeds upon a Liquidation (for the purposes of clarity, any holders of options or
warrants shall only be entitled to receive proceeds in respect thereof if such options or warrants are exercised in connection with such Approved Sale). 
  
 (c) Each holder of Option Shares will be obligated to join on a pro rata basis (applied such that after giving effect thereto, the
aggregate consideration paid to each such 

  

 9. 








 
holder would comply with the provisions of Section 10(b)) in any purchase price adjustments, indemnification or other obligations that the sellers of
Option Shares are required to provide in connection with the Approved Sale (other than any such obligations that relate solely to a particular holder of Option Shares, such as indemnification with respect to representations and warranties given by a
holder regarding such holder’s title to and ownership of Option Shares, in respect of which only such holder will be liable) (and, without limiting the foregoing, in the Company’s sole discretion, the proceeds with respect to an Approved
Sale may be withheld from any holder pending the execution of such documents or posting of security as the Board deems necessary to cover any purchase price adjustments, indemnification or other such obligations of the Company or such holder).

  
 (d) If the Company or the holders of the
Company’s securities enter into any negotiation or transaction for which Rule 506 (or any similar rule then in effect) promulgated by the Securities and Exchange Commission may be available with respect to such negotiation or transaction
(including a merger, consolidation or other reorganization), the holders of Option Shares will, at the request of the Company, appoint a purchaser representative (as such term is defined in Rule 501) reasonably acceptable to the Company. If any
holder of Option Shares appoints a purchaser representative designated by the Company, the Company will pay the fees of such purchaser representative, but if any holder of Option Shares declines to appoint the purchaser representative designated by
the Company, such holder will appoint another purchaser representative, and such holder will be responsible for the fees of the purchaser representative so appointed. 
  
 (e) Each holder of Option Shares will bear their pro rata share (applied such that after giving effect
thereto, the aggregate consideration paid to each such holder would comply with the provisions of Section 10(b)) of the costs of any sale of such Option Shares pursuant to an Approved Sale to the extent such costs are incurred for the benefit
of all holders of Option Shares participating in such Approved Sale and are not otherwise paid by the Company or the acquiring party. Costs incurred by the holders of Option Shares on their own behalf will not be considered costs of the transaction
hereunder; it being understood that the fees and disbursements of one counsel chosen by Parthenon will deemed for the benefit of all holders of Option Shares participating in such Approved Sale. 
  
 (f) If any holder of Option Shares fails to deliver any
certificates representing its Option Shares as required by this Section 10, such holder (i) will not be entitled to the consideration that such holder would otherwise receive in the Approved Sale until such holder cures such failure by
providing the Company with reasonably satisfactory evidence (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing his or its Option Shares, and
indemnify in respect thereto which is reasonably satisfactory to the Company (provided that, after curing such failure, such holder will be so entitled to such consideration without interest), (ii) will be deemed, for all purposes, no longer
to be a stockholder of the Company and will have no voting rights, (iii) will not be entitled to any dividends or other distributions declared after the Approved Sale with respect to the Option Shares held by such holder, (iv) will have no other
rights or privileges granted to the holder of Option Shares under this or any future agreement, and (v) in the event of liquidation of the Company, such holder’s rights with respect to any consideration that such 

  

 10. 








 
holder would have received if such holder had complied with this Section 11, if any, will be subordinate to the rights of any equity holder.

  
 (g) The provisions of this Section 11
shall terminate upon a Public Offering.

Cause) any portion of the Option that was not previously vested and exercisable shall be forfeited. Nothing in this Agreement shall confer upon Executive any right to be selected again as a 2002 Plan participant, and nothing in the 2002 Plan or this
Agreement shall provide for any adjustment to the number of Option Shares subject to the Option upon the occurrence of subsequent events except as provided in Section 16 below. 
  
 15. Indemnification and Reimbursement of Payments on Behalf of Executive. It shall be a condition of the exercise of
