EXHIBIT 10.4

INDEPENDENT CONTRACTOR SERVICES AGREEMENT

THIS AGREEMENT is made as of November 16, 2005, (“Effective Date”) by and between RACKABLE SYSTEMS, INC and its successors or assignees (“Company”) and the undersigned JACK RANDALL (“Contractor”).

1. ENGAGEMENT OF SERVICES. Company may from time to time submit a Statement of Work (“SOW”) to Contractor substantially in the form of Exhibit A to this Agreement. Each SOW shall, when executed by Company and Contractor, form a part of this Agreement and be subject to the terms and conditions set forth herein. Subject to the terms of this Agreement, Contractor will use commercially reasonable efforts to provide the services set forth in each SOW accepted by Contractor (the “Project(s)”) by the completion dates set forth therein. The manner and means that Contractor chooses to complete the Projects are in Contractor’s sole discretion and control. Contractor shall perform the services necessary to complete the Projects in a timely and professional manner consistent with industry standards and at a location, place and time that Contractor deems appropriate. In completing the Projects, Contractor agrees to provide its own equipment, tools, and other materials at its own expense; however, Company will make its facilities and equipment available to Contractor when necessary.

2. COMPENSATION.

2.1 Fees. Company will pay Contractor the fee specified in each SOW as Contractor’s sole compensation for the Project, provided such Project meets the terms of the SOW and this Agreement and is of a quality consistent with industry standards. Contractor shall be responsible for all expenses incurred in performing services under this Agreement, except as set forth in the SOW. Upon termination of this Agreement for any reason prior to completion of an SOW, Company will pay Contractor fees and expenses on the basis stated in the SOW for work which is then in progress, within fifteen (15) days of the later of Contractor’s invoice and the effective date of such termination.

2.2 Invoicing. Unless otherwise provided in the applicable SOW, (a) payment to Contractor of undisputed fees will be due fifteen (15) days following Company’s receipt of an invoice which contains accurate records of the work performed sufficient to document the invoiced fees; and (b) Contractor will submit invoices to Company upon completion of the milestones specified in the applicable SOW or, if no such milestones are specified, on a monthly basis for services performed in the previous month.

3. INDEPENDENT CONTRACTOR RELATIONSHIP. Contractor’s relationship with Company will be that of an independent contractor, and nothing in this Agreement should be construed to create a partnership, joint venture, or employer-employee relationship. Contractor (a) is not the agent of Company; (b) is not authorized to make any representation, contract, or commitment on behalf of Company; (c) will not be entitled to any of the benefits that Company makes available to its employees, such as group insurance, profit-sharing or retirement benefits (and waives the right to receive any such benefits); and (d) will be solely responsible for all tax returns and payments required to be filed with or made to any federal, state, or local tax authority with respect to Contractor’s performance of services and receipt of fees under this Agreement. If applicable, Company will report amounts paid to Contractor by filing Form 1099-MISC with the Internal Revenue Service, as required by law. Contractor agrees to accept exclusive liability for complying with all applicable state and federal laws, including laws governing self-employed individuals, if applicable, such as laws related to payment of taxes, social security, disability, and other contributions based on fees paid to Contractor under this Agreement. Company will not withhold or make payments for social security, unemployment insurance or disability insurance contributions, or obtain workers’ compensation insurance on Contractor’s behalf. Contractor hereby agrees to indemnify and defend Company against any and all such taxes or contributions, including penalties and interest. Contractor agrees to provide proof of payment of appropriate taxes on any fees paid to Contractor under this Agreement upon reasonable request of Company.

7. TERMINATION.

7.1 Termination without Cause. Either party may terminate this Agreement without cause at its convenience upon fifteen (15) days’ prior written notice to the other party.

“Intellectual Property Rights,” “Contractor Representations and Warranties,” “Indemnification,” “Return of Company Property,” “Survival,” and “General Provisions.”

8. MULTI-EMPLOYEE CONTRACTOR. If Contractor will be hiring employees or agents to provide services pursuant to this Agreement, Contractor must obtain Company’s prior written consent to such hiring, and before any Contractor employee or agent performs services in connection with this Agreement or has access to Confidential Information, the employee or agent and Contractor must have entered into a binding written agreement expressly for the benefit of Company that contains provisions substantially equivalent to the sections of this Agreement titled “Engagement of Services” and “Intellectual Property Rights.” At Company’s request, Contractor will provide Company with copies of such agreements. Company reserves the right to refuse or limit Contractor’s use of any employee or agent or to require Contractor to remove any employee or agent already engaged in the performance of the services. Company’s exercise of such right will in no way limit Contractor’s obligations under this Agreement. Contractor agrees (a) that its employees and agents shall not be entitled to or eligible for any benefits that Company may make available to its employees; (b) to limit access to the Confidential Information to employees or agents of Contractor who have a reasonable need to have such access in order to perform the services pursuant to this Agreement; and (c) to be solely responsible for all expenses incurred by any of its employees or agents in performing the services or otherwise performing its obligations under this Agreement, except as set forth in the SOW.

9. LIMITATION OF LIABILITY.

9.1 General Limitation. Contractor’s aggregate liability to Company for damages in connection with this Agreement and the Projects or any Work Product provided pursuant to this Agreement, regardless of the form of action giving rise to such liability (under any theory, whether in contract, tort, statutory or otherwise) shall not exceed the aggregate fees paid by Company to Contractor pursuant to the SOW giving rise to such damages.

9.2 Limitation on Other Damages. To the extent permitted by applicable law and notwithstanding anything in this Agreement to the contrary or any failure of essential purpose of any limited remedy or limitation of liability, Contractor shall not be liable for any indirect, exemplary, special, consequential or incidental damages of any kind, or for any damages resulting from loss or interruption of business, lost data or lost profits, arising out of or relating to this Agreement or the subject matter hereof, however caused, even if Contractor has been advised of or should have known of the possibility of such damages.

10. GENERAL PROVISIONS.

10.1 9.1 Governing Law and Venue. This Agreement and any action related thereto will be governed, controlled, interpreted, and defined by and under the laws of the State of California, without giving effect to any conflicts of laws principles that require the application of the law of a different state. Contractor hereby expressly consents to the personal jurisdiction and venue in the state and federal courts for the county in which Company’s principal place of business is located for any lawsuit filed there against Contractor by Company arising from or related to this Agreement.

10.2 Severability. If any provision of this Agreement is, for any reason, held to be invalid or unenforceable, the other provisions of this Agreement will be unimpaired and the invalid or unenforceable provision will be deemed modified so that it is valid and enforceable to the maximum extent permitted by law.

10.3 No Assignment. This Agreement, and Contractor’s rights and obligations herein, may not be assigned, subcontracted, delegated, or otherwise transferred by Contractor without Company’s prior written consent, and any attempted assignment, subcontract, delegation, or transfer in violation of the foregoing will be null and void. The terms of this Agreement shall be binding upon assignees.

10.4 Notices. Each party must deliver all notices or other communications required or permitted under this Agreement in writing to the other party at the address listed on the signature page, by courier, by certified or registered mail (postage prepaid and return receipt requested), or by a nationally-recognized express mail service. Notice will be effective upon receipt or refusal of delivery. If delivered by certified or registered mail, any such notice will be considered to have been given five (5) business days after it was mailed, as evidenced by the postmark. If delivered by courier or express mail service, any such notice shall be considered to have been given on the delivery date reflected by the courier or express mail service receipt. Each party may change its address for receipt of notice by giving notice of such change to the other party.

10.5 Injunctive Relief. Contractor acknowledges that, because its services are personal and unique and because Contractor will have access to Confidential Information of Company, any breach of this Agreement by Contractor would cause irreparable injury to Company for which monetary damages would not be an adequate remedy and, therefore, will entitle Company to injunctive relief (including specific performance). The rights and remedies provided to each party in this Agreement are cumulative and in addition to any other rights and remedies available to such party at law or in equity.

10.6 Waiver. Any waiver or failure to enforce any provision of this Agreement on one occasion will not be deemed a waiver of any other provision or of such provision on any other occasion.

10.7 Export. Contractor agrees not to export, directly or indirectly, any U.S. technical data acquired from Company or any products utilizing such data, to countries outside the United States, because such export could be in violation of the United States export laws or regulations.

10.8 Remedies. All rights and remedies hereunder shall be cumulative, may be exercised singularly or concurrently and, unless otherwise stated herein, shall not be deemed exclusive. If any legal action is brought to enforce any obligations hereunder, the prevailing party shall be entitled to receive its attorneys’ fees, court costs and other collection expenses, in addition to any other relief it may receive.

10.9 Force Majeure. Both parties shall be excused from performance under this Agreement and any related SOW for any period to the extent that a party is prevented from performing any obligation, in whole or in part, as a result of causes beyond its reasonable control and without its negligent or willful misconduct, including without limitation, acts of God, natural disasters, war or other hostilities, labor disputes, civil disturbances, governmental acts, orders or regulations, third party nonperformance, or failures or fluctuations in electrical power, heat, light, air conditioning or telecommunications equipment.

10.10 Entire Agreement. This Agreement is the final, complete and exclusive agreement of the parties with respect to the subject matters hereof and supersedes and merges all prior discussions between the parties with respect to such subject matters. No modification of or amendment to this Agreement, or any waiver of any rights under this Agreement, will be effective unless in writing and signed by Contractor and CEO of Company. The terms of this Agreement will govern all SOWs and services undertaken by Contractor for Company. In the event of any conflict between this Agreement and a SOW, the terms of the SOW shall govern, but only with respect to the services set forth therein.

IN WITNESS WHEREOF, the parties have caused this Independent Contractor Services Agreement to be executed by their duly authorized representatives.
