COMPANY WARRANT AGREEMENT

Exhibit 10.5

COMPANY WARRANT AGREEMENT

THIS COMPANY WARRANT AGREEMENT (the “Agreement”) is made as of December 23, 2002 (the “Closing Date”), by and between Rackable Corporation, a Delaware corporation (the “Company”), Rackable Investment LLC, a Delaware limited liability company (“Investment LLC”), and Rackable Systems. Inc., a Delaware corporation (“Rackable”). All capitalized terms used herein but not otherwise defined shall have the meanings set forth in the Asset Purchase Agreement (as defined below).

WHEREAS, the Company and Rackable are parties to that certain Asset Purchase Agreement, dated as of the date hereof (the “Asset Purchase Agreement”) pursuant to which, among other things, the Company purchased substantially all of the assets of Rackable;

WHEREAS, part of the consideration for the assets sold pursuant to the Asset Purchase Agreement was the agreement of the Company to enter into this Agreement with Rackable and to issue to Rackable a Company Warrant under certain circumstances and subject to the terms and conditions set forth herein;

WHEREAS, immediately after the consummation of the transactions contemplated by the Asset Purchase Agreement, Rackable holds an aggregate of 7,175,004 shares of Common Stock of the Company, par value $0.001 per share (the “Common Stock”); and

WHEREAS, the Company and Rackable each believe that it is in their respective best interests to enter into this Agreement and consummate the transactions contemplated hereby and by the Asset Purchase Agreement.

NOW, THEREFORE, in consideration of the mutual promises and covenants hereof, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, intending to be legally bound, the parties hereby agree as follows:

1. Issuance of the Company Warrant.

(a) Company Warrant. Subject to the terms and conditions set forth herein, upon the first Potential Warrant Issuance Event in which the Investment Targets are met, the Company shall issue to Rackable a Company Warrant in the Applicable Warrant Share Amount (set forth below) for each Target Level (set forth below) which would be achieved in connection therewith. Notwithstanding anything contained to the contrary herein, the Company shall only be obligated to issue one Company Warrant with respect to each Target Level achieved in connection with the initial Potential Warrant Issuance Event pursuant to this Agreement.

(b) Investment Targets. The “Investment Target” shall be deemed met at the Target Level set forth below, so long as the Investment LLC has achieved (i) an IRR of at least the applicable IRR Target and (ii) an Investment Return greater than or equal to the applicable Investment Return Target set forth opposite such Target Level (assuming, in calculating whether such targets are met, that the Company Warrant applicable to such Target Level was (and the Company Warrants, if any, which would be issued at all lower Target Levels were) issued, outstanding and exercised prior to making such calculation):

For the purposes of clarity, and without limiting the generality of the foregoing, the Company shall issue up to four Company Warrants hereunder depending on the number of Target Levels which have been achieved (assuming, in calculating whether a given Target Level is achieved, that the Company warrant applicable to such Target Level was (and the Company Warrants, if any, which would be issued at all lower Target Levels were) issued, outstanding and exercised prior to making such calculation).

(c) Applicable Warrant Share Amount. The “Applicable Warrant Share Amount” with respect to each Investment Target shall be equal to that percentage of the Company’s Common Stock as set forth below:

For purposes of clarity, and notwithstanding anything to the contrary contained herein, the Parties agree that (i) the Applicable Warrant Share Amounts listed above are separate (not additive; e.g., only one Company Warrant shall be issued upon each Target Level which is achieved) and (ii) no Company Warrant shall be issued if, at minimum, Target Level I is not achieved upon the first Potential Warrant Issuance Event.

(d) Exercise Price. The “Exercise Price” with respect to each Company Warrant issued hereunder shall, at the time of the first Potential Warrant Issuance Event, be set at the price per share of Common Stock which would be necessary for each of the applicable Investment Targets to be met with respect to a given Target Level (assuming, in calculating whether such targets are met, that the Company Warrant applicable to such Target Level was (and the Company Warrants, if any, which would be issued at all lower Target Levels were) issued, outstanding and exercised prior to making such calculation). For the purposes of clarity, and by way of example, the Parties recognize that the Exercise Price for the Company Warrant issued upon the achievement of Target Level I shall be necessarily lower than the Exercise Price for the Company Warrant issued upon achievement of Target Level II).

2.

(e) Termination. Notwithstanding anything to the contrary contained herein, the obligation of the Company to issue any Company Warrants hereunder shall expire and be of no further force and effect following the first Potential Warrant Issuance Event.

(f) Representations and Warranties. In connection with the purchase, sale and issuance of the Company Warrants, and as a condition thereto, Rackable hereby represents and warrants to the Company and the Investment LLC that:

3.

of any statements or opinions as to the advisability of such exchange or investments or as to the properties, business, prospects or condition (financial or otherwise) of the Company or any of its Subsidiaries, which may have been made or given by any such other Person, and such is not being given, or relying upon any legal, accounting or tax advice by the Company, the Investment LLC or its and their officers, directors, members, agents, partners, employees, equityholders, legal or other advisors or its and their Affiliates.

(g) Founders Agreement. The Company and Rackable agree and acknowledge that the Company Warrants and the shares of Common Stock issuable thereby are subject to the terms and conditions of the Founders Repurchase and Rights Agreement, dated as of the date hereof, between the Company, Rackable and certain of Rackable’s stockholders (the “Founders Agreement”) (including, without limitation, the drag-along provisions, transfer restrictions, and other restrictions contained therein).

Any notice provided for in this Agreement must be in writing and must be either personally delivered, mailed by first class mail (postage prepaid and return receipt requested), sent by facsimile (answerback confirmed) or sent by reputable overnight courier service. Any notice under this Agreement will be deemed to have been given when so delivered or sent or, if mailed, five days after deposit in the U.S. mail.

(a) Certain Definitions.

“Affiliate” of any particular Person means any other Person controlling, controlled by or under common control with such particular Person, where “control” means the possession, directly or indirectly, of the power to direct the management and policies of a Person whether through the ownership of voting securities, contract or otherwise.

“Cash Inflows” means, as of a given measurement date, without duplication, all cash payments (excluding expense reimbursements), plus the Fair Market Value of any publicly traded securities, determined by the Company in good faith taking into account the expiration of any lock-up periods or other transfer restrictions, received by the Investment LLC on or before such date with respect to or in exchange for securities of the Company which were issued to the Investment LLC pursuant to the Securities Purchase Agreement (including, without limitation, pursuant to Section 1.4 thereof) (whether such payments are received from the Company or any third party). For the purposes of greater certainty, and without in any way limiting the generality of the foregoing, Cash Inflows shall not include any management fees.

“Cash Outflows” means, as of a given measurement date, without duplication, all cash payments, plus the Fair Market Value of any publicly traded securities, determined by the Company in good faith taking into account the expiration of any lock-up periods or other transfer restrictions, made by the Investment LLC on or before such date (on a cumulative basis) with respect to or in exchange for securities of the Company which were issued to the Investment LLC pursuant to the Securities Purchase Agreement (including, without limitation, pursuant to Section 1.4 thereof) (whether such payments are made to the Company or any third party).

The IRR shall be determined in good faith by the Company. For the purposes of the IRR net present value calculation, each Cash Inflow and each Cash Outflow (i) will be determined as if the Company Warrant with respect to the applicable Target Level (and all lower Target Levels, if any) had previously been issued to Rackable (and exercised by Rackable), and (ii) in the event of any portion of the Cash Inflows are in public securities, the fair market value of such securities shall be determined in good faith by the Company taking into account the expiration of any lock-up periods or other transfer restrictions.

6.

“Sale of the Company” means (i) a sale of all or substantially all of the consolidated assets of the Company to any Person or (ii) the transfer or other disposition to any Person or group of Persons (as the term “group” is defined in the Securities Exchange Act of 1934) (other than Parthenon or any affiliate thereof) of outstanding equity securities (whether by sale, issuance, merger, consolidation, reorganization, combination or otherwise) of the Company such that after giving effect to such transfer, such Person or group of Persons would own or control the right to elect at least a majority of the members of the Board.

(d) Severability. Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

(e) Complete Agreement. This Agreement, those documents expressly referred to herein and other documents of even date herewith embody the complete agreement and understanding among the parties and supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way.

(k) Amendment and Waiver. The provisions of this Agreement may be amended and waived only with the prior written consent of the Company, Rackable and the Investor LLC.

(l) Further Assurances. The Company and Rackable shall execute and deliver such further instruments, documents and agreements, and take such additional action as the Company or Rackable may reasonably request to achieve or further the purposes of this Agreement.

This Warrant (the “Warrant”) is issued pursuant to the terms of the Company Warrant Agreement, dated as of December     , 2002 (the “Company Warrant Agreement”), between the Company, Rackable Systems, Inc. and Rackable Investment LLC. Certain capitalized terms used herein are defined in Sections 2 and 5 hereof. The amount and kind of securities obtainable pursuant to the rights granted hereunder and the purchase price for such securities are subject to adjustment pursuant to the provisions contained in this Warrant. For the purposes hereof, the “Closing Date” shall mean December     , 2002.

This Warrant is subject to the following provisions:

Section 1. Exercise of Warrant.

1A. Exercise Period. The Registered Holder may exercise, in whole or in part (but not as to a fractional share of Common Stock), the purchase rights represented by this Warrant at any time and from time to time after the Date of Issuance to and including the first to occur of (i) December 31, 2007, or (ii) the consummation of a Sale of the Company (the “Exercise Period”).

1B. Exercise Procedure.

(i) This Warrant shall be deemed to have been exercised when the Company has received all of the following items (the “Exercise Time”):

(a) a completed Exercise Agreement, as described in Section 1D below, executed by the Person exercising all or part of the purchase rights represented by this Warrant (the “Purchaser”);

(b) this Warrant;

(c) if this Warrant is not registered in the name of the Purchaser, an Assignment or Assignments in the form set forth in Exhibit II hereto evidencing the assignment of this Warrant to the Purchaser, in which case the Registered Holder shall have complied with the provisions set forth in Section 4 hereof; and

(d) payment to the Company, by check or by wire transfer of immediately available funds, in an amount equal to the product of the Exercise Price multiplied by the number of shares of Common Stock being purchased upon such exercise (the “Aggregate Exercise Price”).

(ii) Certificates for shares of Common Stock purchased upon exercise of this Warrant shall be delivered by the Company to the Purchaser within five business days after the date of the Exercise Time. Unless this Warrant has expired or all of the purchase rights represented hereby have been exercised, the Company shall prepare a new Warrant, substantially identical hereto, representing the rights formerly represented by this Warrant which have not expired or been exercised and shall, within such five-day period, deliver such new Warrant to the Person designated for delivery in the Exercise Agreement.

(iii) The Common Stock issuable upon the exercise of this Warrant shall be deemed to have been issued to the Purchaser at the Exercise Time, and the Purchaser shall be deemed for all purposes to have become the record holder of such Common Stock at the Exercise Time.

(iv) The issuance of certificates for shares of Common Stock upon exercise of this Warrant shall be made without charge to the Company for any issuance tax in respect thereof or other cost incurred by the Purchaser in connection with such exercise and the related issuance of shares of Common Stock. Each share of Common Stock issuable upon exercise of this Warrant shall, upon payment of the Exercise Price therefor, be fully paid and nonassessable and free from all liens and charges with respect to the issuance thereof. The Company shall be entitled, as a condition to the exercise of this Warrant, to withhold or deduct any federal, state, local or foreign withholding taxes, excise taxes, or employment taxes imposed with respect hereto.

(v) The Company shall not close its books against the transfer of this Warrant or of any share of Common Stock issued or issuable upon the exercise of this Warrant in any manner which interferes with the timely exercise of this Warrant.

2.

(vi) Notwithstanding any other provision hereof, if an exercise of any portion of this Warrant is to be made in connection with a Qualified Public Offering, the Sale of the Company or a Recapitalization of the Company, the exercise of any portion of this Warrant may, at the election of the holder hereof, be conditioned upon the consummation of such Public Offering, Sale of the Company or Recapitalization of the Company in which case such exercise shall be deemed to be effective simultaneously with the consummation of such transaction.

1C. Net Exercise. Notwithstanding any provisions herein to the contrary, if the fair market value of one share of Common Stock is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant by payment of cash, the Registered Holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Exercise Agreement in which event the Company shall issue to the Registered Holder a number of shares of Common Stock computed using the following formula

For purposes of the above calculation, the fair market value of one share of Common Stock shall be determined by the Company’s Board of Directors in good faith.

1D. Exercise Agreement. Upon any exercise of this Warrant, the Exercise Agreement shall be substantially in the form set forth in Exhibit I hereto, except that if the shares of Common Stock are not to be issued in the name of the Person in whose name this Warrant is registered, the Exercise Agreement shall also state the name of the Person to whom the certificates for the shares of Common Stock are to be issued, and if the number of shares of Common Stock to be issued does not include all the shares of Common Stock purchasable hereunder, it shall also state the name of the Person to whom a new Warrant for the unexercised portion of the rights hereunder is to be delivered. Such Exercise Agreement shall be dated the actual date of execution thereof.

1E. Fractional Shares. If a fractional share of Common Stock would, but for the provisions of Section 1A, be issuable upon exercise of the rights represented by this Warrant, the Company shall, at its option, within five (5) business days after the date of the Exercise Time, deliver to the Purchaser either (i) a check payable to the Purchaser in lieu of such fractional share in an amount equal to the difference between the market price of such fractional share as of the date of the Exercise Time and the Exercise Price of such fractional share or (ii) deliver such fractional shares of Common Stock.

3.

Section 2. Definitions. The following terms have meanings set forth below:

“Common Stock” means the Company’s Common Stock, par value $0.001 per share.

“Person” means an individual, a partnership, a joint venture, a corporation, a limited liability company, a trust, an unincorporated organization and a government or any department or agency thereof.

Other capitalized terms used in this Warrant but not defined herein shall have the meanings set forth in the Company Warrant Agreement.

Section 3. No Voting or Other Rights. This Warrant shall not entitle the holder hereof to any voting rights or other rights as a stockholder of the Company.

Section 4. Warrant Transferable. Subject at all times to the transfer conditions referred to in the legend endorsed hereon, this Warrant and all rights hereunder shall not be transferable, in whole or in part, (i) except pursuant to the terms and conditions of the Founders Repurchase and Rights Agreement, dated as of the date hereof, by and among the Company, Rackable Systems, Inc. and the other parties thereto, or (ii) except in connection with a distribution or other transfer from the Registered Holder to its equity holders, and in each case unless accompanied by the surrender of this Warrant with a properly executed Assignment (in the form of Exhibit II hereto) at the principal office of the Company.

Section 5. Warrant Exchangeable for Different Denominations. This Warrant is exchangeable, upon the surrender hereof by the Registered Holder at the principal office of the Company, for a new Warrant of like tenor representing in the aggregate the purchase rights hereunder, and each such new Warrant shall represent such portion of such rights as is designated by the Registered Holder at the time of such surrender. The date the Company initially issues this Warrant shall be deemed to be the “Date of Issuance” hereof regardless of the number of times new certificates representing the unexpired and unexercised rights formerly represented by this Warrants shall be issued. All Warrants representing portions of the rights hereunder are referred to herein as the “Warrant.”

Section 6. Adjustments.

6A. Stock Splits and Dividends. If outstanding shares of Common Stock shall be subdivided into a greater number of shares or a dividend in Common Stock shall be paid in respect of Common Stock, the Exercise Price in effect immediately prior to such subdivision or at the record date of such dividend shall simultaneously with the effectiveness of such subdivision or immediately after the record date of such dividend be proportionately reduced. If outstanding shares of Common Stock shall be combined into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall, simultaneously with the effectiveness of such combination, be proportionately increased. When any adjustment is required to be made in the Exercise Price, the number of shares of Common Stock purchasable upon the exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Exercise Price in effect immediately prior to such adjustment, by (ii) the Exercise Price in effect immediately after such adjustment.

6B. Reclassification. In case there occurs any reclassification of the Company’s Common Stock issuable upon exercise of this Warrant on or after the date hereof, then and in such case the Registered Holder, upon the exercise hereof at any time after the consummation of such reclassification shall be entitled to receive, in lieu of the Common Stock receivable upon the exercise

4.

hereof prior to such consummation, the stock or other securities or property to which such Registered Holder would have been entitled upon such consummation if such Registered Holder had exercised this Warrant immediately prior thereto, all subject to further adjustment pursuant to the provisions of this Section 6.

6C. Adjustment Certificate. When any adjustment is required to be made in the Common Stock or the Exercise Price pursuant to this Section 6, the Company shall promptly mail to the Registered Holder a certificate setting forth (i) a brief statement of the facts requiring such adjustment, (ii) the Exercise Price after such adjustment, and (iii) the kind and amount of stock or other securities or property into which this Warrant shall be exercisable after such adjustment.

Section 7. Replacement. Upon receipt of evidence reasonably satisfactory to the Company (an affidavit of the Registered Holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing this Warrant, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Company (provided that if the holder is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Company shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the same rights represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate.

Section 8. Notices. Except as otherwise expressly provided herein, all notices referred to in this Warrant shall be in writing and shall be delivered personally, sent by reputable overnight courier service (charges prepaid) or sent by registered or certified mail, return receipt requested, postage prepaid and shall be deemed to have been given when so delivered, sent or deposited in the U.S. Mail (i) to the Company, at its principal executive offices and (ii) to the Registered Holder of this Warrant, at such holder’s address as it appears in the records of the Company (unless otherwise indicated by any such holder).

Section 9. Amendment and Waiver. The provisions of this Warrant may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Registered Holders of Warrants representing, in the aggregate, a majority of the shares of Common Stock obtainable upon exercise of this Warrant.

Section 10. Descriptive Headings; Governing Law. The descriptive headings of the several Sections and paragraphs of this Warrant are inserted for convenience only and do not constitute a part of this Warrant. The corporation laws of the State of Delaware shall govern all issues concerning the relative rights of the Company and its stockholders. All other questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by the internal law of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of Delaware.
