                                WARRANT AGREEMENT

     This Agreement made as of ______ __, 2006 between Geneva Acquisition
Corporation, a Delaware corporation, with offices at One Boston Place, Suite
3630, Boston, Massachusetts 02108 ("Company"), and Continental Stock Transfer &
Trust Company, a New York corporation, with offices at 17 Battery Place, New
York, New York 10004 ("Warrant Agent").

     WHEREAS, the Company is engaged in a public offering ("Public Offering") of
Units ("Units") and, in connection therewith, has determined to issue and
deliver (i) up to 23,000,000 Warrants, including 3,000,000 Warrants that may be
issued to Ladenburg Thalmann & Co. Inc. ("LTC"), as representative of the
underwriters (the "Underwriters"), upon exercise of its over-allotment option,
to the public investors (the "Public Warrants"); (ii) up to 1,000,000 Warrants
to LTC or its designee ("Representative's Warrants"); and (iii) 2,155,000
Warrants to certain of the initial stockholders of the Company (the "Placement
Warrant Purchasers") in a private placement (the "Placement Warrants") (the
Public Warrants, the Representative's Warrants and the Placement Warrants are
herein collectively referred to as the "Warrants"). Each Warrant evidences the
right of the holder thereof to purchase one share of common stock, par value
$0.0001 per share, of the Company's Common Stock ("Common Stock") for the
Warrant Price described herein, subject to adjustment as described herein; and

     WHEREAS, the Company has filed with the Securities and Exchange Commission
a Registration Statement on Form S-1, No. 333-______ (the "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; and

     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 and exercise of the
Warrants; and

     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,
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, Chief Executive Officer or President, and Chief
Financial Officer, 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.

<Page>

     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  REGISTRATION.

          2.3.1 WARRANT REGISTER. The Warrant Agent shall maintain books
("Warrant Register"), for the 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.

          2.3.2 REGISTERED HOLDER. 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 ("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 DETACHABILITY OF WARRANTS. The securities comprising the Units will
not be separately transferable until 90 days after the date hereof unless LTC
informs the Company of its decision to allow earlier separate trading, but in no
event will LTC allow separate trading of the securities comprising the Units
until the Company files a Current Report on Form 8-K which includes an audited
balance sheet reflecting the receipt by the Company of the gross proceeds of the
Public Offering including the proceeds received by the Company from the exercise
of the Underwriter's over-allotment option, if the over-allotment option is
exercised prior to the filing of the Form 8-K.

     2.5 WARRANT ATTRIBUTES. The Placement Warrants and Representative's
Warrants shall have the same terms and be in the same form as the Public
Warrants.

3.   TERMS AND EXERCISE OF WARRANTS.

     3.1 WARRANT PRICE. Each Warrant shall, when countersigned by the Warrant
Agent, entitle the registered holder thereof, subject to the provisions of such
Warrant and of this Warrant Agreement, to purchase from the Company the number
of shares of Common Stock stated therein, at the price of $5.00 per whole share,
subject to the adjustments provided in Section 4 hereof and in the last sentence
of this Section 3.1. 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; provided, however, that any such
price reduction shall be in effect for a period of not less than ten (10)
business days, and that any change in the Warrant Price must apply equally to
all of the Warrants.

     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 ("Business Combination") (as described more fully in the Company's
Registration Statement) or _________ ____, 2007, and terminating at 5:00 p.m.,
New York City local time on the earlier to occur of (i) ________ __, 2010 or
(ii) the date fixed for redemption of the Warrants as provided in Section 6 of
this Agreement ("Expiration Date"). Except with respect to the right to receive
the Redemption Price (as set forth in Section 6 hereunder), 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;
provided, however, that the Company will provide notice to Registered Holders of
any extension of not less than 20 days and that any extension of the duration of
the Warrants must apply equally to all of the Warrants.

                                        2

     3.3  EXERCISE OF WARRANTS.

          3.3.1 PAYMENT. Subject to the provisions of the Warrant and this
Warrant Agreement, a Warrant, when countersigned by the Warrant Agent, may be
exercised by the registered holder thereof by surrendering it, at the office of
the Warrant Agent, or at the office of its successor as Warrant Agent, in the
Borough of Manhattan, City and State of New York, with the subscription form, as
set forth in the Warrant, duly executed, and by paying in full the Warrant Price
for each full share of Common Stock as to which the Warrant is exercised and any
and all applicable taxes due in connection with the exercise of the Warrant, as
follows:

          (a) in cash, good certified check or good bank draft payable to the
     order of the Company (or as otherwise agreed to by the Company); or

          (b) with respect to any Placement Warrants, in the event of redemption
     pursuant to Section 6 hereof, so long as such Placement Warrants are held
     by the Placement Warrant Purchasers or their affiliates, by surrendering
     the Placement Warrants for that number of shares of Common Stock equal to
     the quotient obtained by dividing (x) the product of the number of shares
     of Common Stock underlying the Placement Warrants, multiplied by the
     difference between the Warrant Price and the "Fair Market Value" (defined
     below) by (y) the Fair Market Value. Solely for purposes of this Section
     3.3.1(b), the "Fair Market Value" shall mean the average reported last sale
     price of the Common Stock for the 10 trading days ending on the third
     trading day prior to the date on which the notice of redemption is sent to
     holders of Warrant pursuant to Section 6 hereof.

          3.3.2 ISSUANCE OF CERTIFICATES. As soon as practicable after the
exercise of any Warrant and the clearance of the funds in payment of the Warrant
Price, the Company shall issue to the registered holder of such Warrant a
certificate or certificates for the number of full shares of Common Stock to
which he is entitled, registered in such name or names as may be directed by
him, her or it, and if such Warrant shall not have been exercised in full, a new
countersigned Warrant for the number of shares as to which such Warrant shall
not have been exercised. 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. In the
event a registration statement under the Act with respect to the Common Stock
underlying the Warrants is not effective, or because such exercise would be
unlawful with respect to a registered holder in any state, the registered holder
shall not be entitled to exercise such Warrants and such Warrants may have no
value and expire worthless. In no event will the Company be obligated to pay
such registered holder any cash or other consideration or otherwise "net cash
settle" the Warrant. Furthermore, in the event that a registration statement is
not effective under the Act with respect to the Common Stock underlying the
Warrants, the purchaser of a Unit containing such Warrant will have paid the
full purchase price for the Unit solely for the shares included in such Unit.

          3.3.3 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.

          3.3.4 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

                                        3

<Page>

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 or down 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

                                        4

<Page>

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 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 cancelled by the
Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent
to the Company from time to time upon request.

     5.2 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 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.

     5.3 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.

     5.4 SERVICE CHARGES. No service charge shall be made for any exchange or
registration of transfer of Warrants.

     5.5 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.

     6.1 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 their expiration, at the office of
the Warrant Agent, upon the notice referred to in Section 6.2, at the price of
$0.01 per Warrant ("Redemption Price"), provided that the last sales price of
the Common Stock has been at least $8.50 per share, on each of twenty (20)
trading days within any 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 a date for the
redemption. Notice of redemption shall be mailed by first class mail, postage
prepaid, by the Company not less than 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. Any notice mailed
in the manner herein provided shall be conclusively presumed to have been duly
given 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 after notice of
redemption 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

                                        5

<Page>

Company may redeem the Warrants issued upon such exercise provided that the
criteria for redemption is met. The provisions of this Section 6.4 may not be
modified, amended or deleted without the prior written consent of LTC.

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

(unless other evidence in respect thereof be herein specifically prescribed) may
be deemed to be conclusively proved and established by a statement signed by the
Chief Executive Officer, President or Chairman of the Board of the Company and
delivered to the Warrant Agent. The Warrant Agent may rely upon such statement
for any action taken or suffered in good faith by it pursuant to the provisions
of this Agreement.

          8.4.2 INDEMNITY. The Warrant Agent shall be liable hereunder only for
its own negligence, willful misconduct or bad faith. The Company agrees to

liabilities, including judgments, costs and reasonable counsel fees, for
anything done or omitted by the Warrant Agent in the execution of this Agreement
except as a result of the Warrant Agent's negligence, willful misconduct, or bad
faith.
