WHEREAS, the Company has filed with the Securities and Exchange Commission (the "SEC") a Registration Statement, No. 333-126355 on Form S-1 ("Registration Statement") for the registration, under the Securities Act of 1933, as amended ("Act") of, among other securities, the Warrants and the Common Stock issuable upon exercise of the Warrants;

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration, transfer, exchange, redemption, exercise and cancellation of the Warrants;

WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the holders of the Warrants; and

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent, as provided herein, the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Agreement.

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement.

2. Warrants.

2.1 Form of Warrant. Each Warrant shall be issued in registered form only evidenced by a Warrant Certificate, shall be in substantially the form of Exhibit A hereto, the provisions of which are incorporated herein and shall be signed by, or bear the facsimile signature of, the Chairman of the Board or Chief Executive Officer and Treasurer, Secretary or Assistant Secretary of the Company and shall bear a facsimile of the Company's seal. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance. All of the Warrants

shall initially be represented by one or more Book-Entry certificates (each a "Book Entry Warrant Certificate").

2.2 Effect of Countersignature. Unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

2.3 Detachability of Warrants. The securities comprising the Units will not be separately transferable until (A) the 20^th trading day after the earlier of the expiration of the underwriters' over-allotment option and the exercise in full by the underwriters of such option and (B) the Company files a Current Report on Form 8-K which includes an audited balance sheet reflecting the receipt by the Company of the net proceeds of the Public Offering, including the proceeds received by the Company from the exercise of the underwriters' over-allotment option (the "Detachment Date").

2.4 Registration.

2.4.1 Warrant Register. The Warrant Agent shall maintain books ("Warrant Register"), for registration of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. All of the Warrants shall initially be represented by one or more Book-Entry Warrant Certificates deposited with the Depository Trust Company (the "Depository") and registered in the name of Cede & Co., a nominee of the Depository. Ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by (i) the Depository or its nominee for each Book-Entry Warrant Certificate, or (ii) institutions that have accounts with the Depository (such institution, with respect to a Warrant in its account, a "Participant").

If the Depository subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depository to deliver to the Warrant Agent for cancellation each Book-Entry Warrant Certificate, and the Company shall instruct the Warrant Agent to deliver to the Depository definitive Warrant Certificates in physical form evidencing such Warrants. Such definitive Warrant Certificates shall be in the form annexed hereto as Exhibit A with appropriate insertions, modifications and omissions, as provided above.

2.4.2 Beneficial Owner; Registered Holder. The term "beneficial owner" shall mean, on or after the Detachment Date, any person in whose name ownership of a beneficial interest in the Warrants evidenced by a Book-Entry Warrant Certificate is recorded in the records maintained by the Depository or its nominee, and prior to the Detachment Date, the person in whose name the Unit to which such Warrant Certificate was initially attached as registered upon the register relating to such Units. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant shall be registered upon the Warrant Register (a "Registered Holder"), as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on the Warrant Certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

2.4.3 Warrants and Representative's Warrants. The Representative's Warrants shall have the same terms and be in the same form as the Public Warrants and the Insider Warrants except with respect to the Warrant Price as set forth below in Section 3.1.

3. Terms and Exercise of Warrants

3.1 Warrant Price. Each Public Warrant and Insider Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof, subject to the provisions of (a) such Public Warrant or Insider Warrant, as the case may be, and (b) this Warrant Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $6.00 per whole share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. Each Representative's Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof, subject to the provisions of such Representative's Warrant and of this Warrant Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $7.98 per whole share, subject to the adjustments provided in Section 4 hereof. The term "Warrant Price" as used in this Warrant Agreement refers to the price per share at which Common Stock may be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration Date.

3.2 Duration of Warrants. A Warrant may be exercised only during the period ("Exercise Period") commencing on the later of the consummation by the Company of a merger, capital stock exchange, asset acquisition or other similar business combination of one or more operating businesses in the technology-related sector having, individually or collectively, a fair market value (as calculated in accordance with the Company's Certificate of Incorporation) at least equal to 80% of the Company's net assets at the time of such acquisition (a "Business Combination") and , 2006, and terminating at 5:00 p.m., New York City time on the earlier to occur of (i) , 2010 and (ii) the Redemption Date (as defined in Section 6 of this Agreement (the "Expiration Date"). Except with respect to the right to receive the Redemption Price (as set forth in Section 6 hereunder) in the case of a redemption by the Company, each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at the close of business on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date.

3.3 Exercise of Warrants. A Registered Holder may exercise a Warrant by delivering, not later than 5:00 P.M., New York time, on any Business Day during the Exercise Period (the "Exercise Date") to the Warrant Agent at its corporate trust department (i) the Warrant Certificate evidencing the Warrants to be exercised, or, in the case of a Book-Entry Warrant Certificate, the Warrants to be exercised (the "Book-Entry Warrants") free on the records of the Depository to an account of the Warrant Agent at the Depository designated for such purpose in writing by the Warrant Agent to the Depository from time to time, (ii) an election to purchase the Shares underlying the Warrants to be exercised ("Election to Purchase"), properly completed and executed by the Registered Holder on the reverse of the Warrant Certificate or, in the case of a Book-Entry Warrant Certificate, properly delivered by the Participant in accordance with the Depository's procedures, and (iii) the Exercise Price for each Warrant to be exercised in lawful money of the United States of America by certified or official bank check or by bank wire transfer in immediately available funds. If any of (A) the Warrant Certificate or the Book-Entry Warrants, (B) the Election to Purchase, or (C) the Exercise Price therefor, is received by the Warrant Agent after 5:00 P.M., New York time, on the specified Exercise Date, the Warrants will be deemed to be received and exercised on the Business Day next succeeding the Exercise Date. If the date specified as the Exercise Date is not a Business Day, the Warrants will be deemed to be received and exercised on the next succeeding day that is a Business Day. If the Warrants are received or

deemed to be received after the Expiration Date, the exercise thereof will be null and void and any funds delivered to the Warrant Agent will be returned to the Registered Holder or Participant, as the case may be, as soon as practicable. In no event will interest accrue on funds deposited with the Warrant Agent in respect of an exercise or attempted exercise of Warrants. The validity of any exercise of Warrants will be determined by the Company in its sole discretion and such determination will be final and binding upon the Registered Holder and the Warrant Agent. Neither the Company nor the Warrant Agent shall have any obligation to inform a Registered Holder of the invalidity of any exercise of Warrants.

The Warrant Agent shall deposit all funds received by it in payment of the Exercise Price in the account of the Company maintained with the Warrant Agent for such purpose and shall advise the Company at the end of each day on which funds for the exercise of the Warrants are received of the amount so deposited to its account. The Warrant Agent shall promptly confirm such telephonic advice to the Company in writing.

(i) The Warrant Agent shall, by 11:00 A.M. on the Business Day following the Exercise Date of any Warrant, advise the Company and the transfer agent and registrar in respect of (a) the shares of Common Stock (the "Shares") issuable upon such exercise as to the number of Warrants exercised in accordance with the terms and conditions of this Agreement, (b) the instructions of each Registered Holder or Participant, as the case may be, with respect to delivery of the Shares issuable upon such exercise, and the delivery of definitive Warrant Certificates, as appropriate, evidencing the balance, if any, of the Warrants remaining after such exercise, (c) in case of a Book-Entry Warrant Certificate, the notation that shall be made to the records maintained by the Depository, its nominee for each Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance, if any, of the Warrants remaining after such exercise and (d) such other information as the Company or such transfer agent and registrar shall reasonably require.

(ii) The Company shall, by 5:00 P.M., New York time, on the third Business Day next succeeding the Exercise Date of any Warrant and the clearance of the funds in payment of the Warrant Price, execute, issue and deliver to the Warrant Agent, the Shares to which such Registered Holder is entitled, in fully registered form, registered in such name or names as may be directed by such Holder or the Participant, as the case may be. Upon receipt of such Shares, the Warrant Agent shall, by 5:00 P.M., New York time, on the fifth Business Day next succeeding such Exercise Date, transmit such Shares, to or upon the order of the Registered Holder or Participant, as the case may be.

In lieu of delivering physical certificates representing the Shares issuable upon exercise, provided the Company's transfer agent is participating in the Depository Fast Automated Securities Transfer program, the Company shall use its reasonable best efforts to cause its transfer agent to electronically transmit the Shares issuable upon exercise to the Registered Holder or Participant by crediting the account of the Registered Holder's prime broker with the Depository or of the Participant through its Deposit Withdrawal Agent Commission system. The time periods for delivery described in the immediately preceding paragraph shall apply to the electronic transmittals described herein. Notwithstanding the foregoing, the Company shall not be obligated to deliver any securities pursuant to the exercise of a Warrant unless a registration statement under the Act with respect to the Common Stock is effective. Warrants may not be exercised by, or securities issued to, any Registered Holder in any state in which such exercise would be unlawful.

(iii) The accrual of dividends, if any, on the Shares issued upon the valid exercise of any Warrant will be governed by the terms generally applicable to the Shares. From and after the issuance of such Shares, the former Registered Holder of the Warrants exercised will be

entitled to the benefits generally available to other holders of Shares and such former Registered Holder's right to receive payments of dividends and any other amounts payable in respect of the Shares shall be governed by, and shall be subject to, the terms and provisions generally applicable to such Shares.

(iv) Warrants may be exercised only in whole numbers of Warrants. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number. If fewer than all of the Warrants evidenced by a Warrant Certificate are exercised, a new Warrant Certificate for the number of Warrants remaining unexercised shall be executed by the Company and countersigned by the Warrant Agent as provided in Section 2 hereof, and delivered to the holder of this Warrant Certificate at the address specified on the books of the Warrant Agent or as otherwise specified by such Registered Holder. If fewer than all the Warrants evidenced by a Book-Entry Warrant Certificate are exercised, a notation shall be made to the records maintained by the Depository, its nominee for each Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance of the Warrants remaining after such exercise.

(v) The Company shall not be required to pay any stamp or other tax or governmental charge required to be paid in connection with any transfer involved in the issue of the Shares upon the exercise of Warrants; and in the event that any such transfer is involved, the Company shall not be required to issue or deliver any Shares until such tax or other charge shall have been paid or it has been established to the Company's satisfaction that no such tax or other charge is due.

3.4 Valid Issuance. All shares of Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and nonassessable.

3.5 Date of Issuance. Each person in whose name any such certificate for shares of Common Stock is issued shall for all purposes be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open.

4. Adjustments.

4.1 Stock Dividends—Split-Ups. If after the date hereof, and subject to the provisions of Section 4.6 below, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of Common Stock, or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased in proportion to such increase in outstanding shares of Common Stock.

4.2 Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.6, the number of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding shares of Common Stock.

4.3 Adjustments in Exercise Price. Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted, as provided in Section 4.1 and 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price

immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter.

4.4 Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common Stock (other than a change covered by Section 4.1 or 4.2 hereof or that solely affects the par value of such shares of Common Stock), or in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Warrant holders shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the Warrant holder would have received if such Warrant holder had exercised his, her or its Warrant(s) immediately prior to such event; and if any reclassification also results in a change in shares of Common Stock covered by Section 4.1 or 4.2, then such adjustment shall be made pursuant to Sections 4.1, 4.2, 4.3 and this Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers.

4.5 Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, then, in any such event, the Company shall give written notice to the Warrant holder, at the last address set forth for such holder in the warrant register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.

4.6 No Fractional Shares. Notwithstanding any provision contained in this Warrant Agreement to the contrary, the Company shall not issue fractional shares upon exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round up to the nearest whole number the number of the shares of Common Stock to be issued to the Warrant holder.

4.7 Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrants initially issued pursuant to this Agreement. However, the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

5. Transfer and Exchange of Warrants.

5.1 Transfer of Warrants. Prior to the Detachment Date, Warrants may be transferred or exchanged only together with the Unit in which such Warrant is included, and only for the purpose of effecting, or in conjunction with, a transfer or exchange of such Unit. Furthermore, prior to the Detachment Date, each transfer of a Unit on the register relating to such Units shall operate also to transfer the Warrants included in such Unit. From and after the Detachment Date, this Section 5.1 shall be of no further force and effect.

5.2 Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be canceled by the Warrant Agent. The Warrants so canceled shall be delivered by the Warrant Agent to the Company from time to time upon request.

5.3 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the registered holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that except as otherwise provided herein or in any Book-Entry Warrant Certificate, each Book-Entry Warrant Certificate may be transferred only in whole and only to the Depository, to another nominee of the Depository, to a successor depository, or to a nominee of a successor depository; provided further, however, that in the event that a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange therefor until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend. Upon any such registration of transfer, the Company shall execute, and the Warrant Agent shall countersign and deliver, in the name of the designated transferee a new Warrant Certificate or Warrant Certificates of any authorized denomination evidencing in the aggregate a like number of unexercised Warrants.

5.4 Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the issuance of a warrant certificate for a fraction of a Warrant.

5.5 Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.

5.6 Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, will supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

6. Redemption.

Subject to Section 6.4 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of the Company, at any time after they become exercisable and prior to , 2010, at the office of the Warrant Agent, upon the notice referred to in Section 6.2, at the price of $.01 per Warrant ("Redemption Price"), provided that the last sales price of the Common Stock has been at least $11.50 per share on each of any twenty (20) trading days within a thirty (30) trading day period ending on the third Business Day prior to the date on which notice of redemption is given.

6.2 Date Fixed for, and Notice of, Redemption. In the event the Company shall elect to redeem all of the Warrants, the Company shall fix the Redemption Date). Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than thirty (30) days prior to the date fixed for redemption to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration books (the "Redemption Notice"). Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given on the date sent whether or not the Registered Holder received such notice.

6.3 Exercise After Notice of Redemption. The Warrants may be exercised in accordance with Section 3 of this Agreement at any time the Redemption Notice shall have been given by the Company pursuant to Section 6.2 hereof and prior to the time and date fixed for redemption. On and after the Redemption Date, the record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price.

6.4 Outstanding Warrants Only. The Company understands that the redemption rights provided for by this Section 6 apply only to outstanding Warrants. To the extent a person holds rights to purchase Warrants, such purchase rights shall not be extinguished by redemption. However, once such purchase rights are exercised, the Company may redeem the Warrants issued upon such exercise provided that the criteria for redemption is met.

7. Other Provisions Relating to Rights of Holders of Warrants.

7.1 No Rights as Stockholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of the Company or any other matter.

7.2 Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost, stolen, mutilated, or destroyed, the Company and the Warrant Agent may, on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.

7.3 Reservation of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.
