COMMON STOCK SUBSCRIPTION AGREEMENT  

        Boomerang Holdings, Inc., a Delaware corporation ("Company") and the Investor hereby enter into this Common
Stock Subscription Agreement (this "Subscription Agreement") agree as follows: 

        1.    Subscription for Common Stock.    I (sometimes referred to herein as the
"Investor") hereby subscribe for and agree to
purchase                        shares of the Company's Common Stock (the "Common
Stock") at a price of $0.01 per share for a total of $            . Investor is subscribing for the Common Stock as part of a private placement by the Company of
up to
720,000 shares of Common Stock (the "Private Placement"). The Private Placement shall be on the terms set forth in that certain Private Placement
Memorandum ("PPM") attached hereto as Exhibit A. 

        2.    Offering Period; Maximum.    The offering of the Common Stock is on a "best efforts,"
$7,200 maximum basis. There is no minimum amount of aggregate investment that must be received by the Company in order for there to be a closing of the Private Placement. 

        3.    Closing.    The Company expects the closing of the Private Placement (the
"Closing") to occur                        , 2006, or such other date to
which the Company, in its sole discretion, shall determine to extend the Private
Placement. 

        4.    Investor Delivery of Payment and Documents.    

        4.1.  Concurrently
herewith, I have tendered the full purchase price for the Common Stock by one or a combination of the following means: 

        (a)   wiring
funds in accordance with the instructions set forth in Section 1 to Schedule 1; or 

        (b)   by
delivery of a check in accordance with the instructions set forth in Section 2 of Schedule 1.

        4.2.  I
hereby tender to the Company an executed copy of this Subscription Agreement. 

        4.3.  In
the event that a Closing does not take place with respect to any subscription for any reason or if my subscription is otherwise rejected, all cash proceeds delivered
by me in accordance with the foregoing shall be returned to me as soon as practicable, without interest, offset or deduction. 

        4.4.  In
the event my subscription is accepted and there is a Closing, the Common Stock for which I am subscribing will be delivered promptly to me along with a copy of a
fully executed version of this Subscription Agreement. 

        5.    Acceptance or Rejection of Subscription Agreement.    The Company has the right to
reject this subscription for the Common Stock, in whole or in part, for any reason and at any time prior to the Closing, notwithstanding prior receipt by me of notice of acceptance of my subscription.
The Common Stock subscribed for herein will not be deemed issued to or owned by me until a copy of this Subscription Agreement has been executed by me and countersigned by the Company, and a Closing
with respect to my subscription has occurred. 

        6.    Private Placement to Certain Investors.    The Private Placement is limited to
accredited investors as defined by Rule 501(a) of Regulation D promulgated under the Securities Act of 1933, as amended (the "Securities
Act") and a limited number of nonaccredited investors pursuant to Section 4(2) of the Securities Act and Rule 506 promulgated thereunder on the terms set forth in
the PPM. 

 

        7.    Investor Representations and Warranties.    I acknowledge, represent and warrant to the
Company as follows: 

        7.1.    Obligations of the Company and the Investor.    The Company has no obligation to me other than as set forth in
this Subscription Agreement. I am aware that, except for any rescission rights that may be provided under applicable laws, I am not entitled to cancel, terminate or revoke this subscription and any
agreements made in connection herewith will survive my death or disability. In order to induce the Company to issue and sell the Common Stock to me, I represent and warrant that the information
relating to me stated herein is true and complete as of the date hereof and will be true and complete as of the date on which my purchase of the Common Stock becomes effective. If, prior to the later
to occur of (a) the Closing, and (b) the effective date of the registration statement (the "Registration Statement") filed for registering
the Company's securities in the proposed public offering (the "Public Offering") as described in the PPM, there should be any change in such information
or any of such information becomes incorrect or incomplete, I agree to notify the Company and supply the Company promptly with corrective information. 

        7.2.    Information About the Company.    

        (a)   I
have been given reasonable opportunity to meet with officers of the Company for the purpose of asking reasonable questions of such officers concerning the terms and
conditions of the Private Placement, the business objectives of the Company and all such questions have been answered to my full satisfaction. I understand that the Company is a blank check company
recently formed for the purpose of acquiring through a purchase, asset acquisition or other combination, one or more businesses engaged in the oil and gas industry, and in particular, the oilfield
services sector. I have also been given an opportunity to obtain any additional relevant information to the extent reasonably available to the Company. I have received all information regarding the
Company that I have reasonably requested. I understand that there is no assurance as to the future performance of the Company and that the Company may never effectuate a business combination. For
purposes of this Agreement, a "business combination" means, following the Public Offering (the net proceeds of which shall be deposited in a trust
account), the Company's initial acquisition of one or more assets or operating businesses through a merger, capital stock exchange, asset or stock acquisition or other similar business combination
pursuant to which the Company will require that a majority of the shares of common stock voted by its public stockholders are voted in favor of the acquisition and less than 20% of the public
stockholders both (1) vote against the proposed acquisition and (2) elect to convert their shares of common stock into a pro rata share of the aggregate amount then on deposit in the
trust account, as described in the PPM. 

        (b)   I
have read and fully understand the PPM. I have read and fully understand the risks regarding the Company set forth under the caption "Risk Factors" in the PPM. 

        7.3.    No assurances; No general solicitation.    I have received no representation or warranty from the Company or
any of its officers, directors, employees or agents in respect of my investment in the Company. I am not participating in the Private Placement as a result of or subsequent to: (i) any
advertisement, article, notice or other communication published in any newspaper, magazine or similar media or broadcast over television, radio or the Internet or (ii) any seminar or meeting
whose attendees have been invited by any general solicitation or general advertising. 

        7.4.    Speculative Investment.    I am aware that my purchase of the Common Stock is a speculative investment. I
acknowledge that I can lose the entire amount of my investment in the Company. I have been urged to seek independent advice from my professional advisors relating to the suitability of an investment
in the Company in view of my overall financial needs and with 

2

 

respect
to the legal and tax implications of such investment. I believe that the investment in the Company represented by my purchase of the Common Stock in the Private Placement is suitable for me
based upon my investment objectives and financial needs, and I have adequate means for providing for my current financial needs and contingencies and have no need for liquidity with respect to my
investment in the Company. My investment in the Company does not constitute all, or substantially all, of my investment portfolio. 

        7.5.    Restrictions on Transfer.    I understand that (i) the Common Stock has not been registered under the
Securities Act or the securities laws of certain states in reliance on specific exemptions from registration, (ii) no securities administrator of any state or the federal government has
recommended or endorsed this Private Placement or made any finding or determination relating to the fairness of an investment in the Company, and (iii) the Company is relying on my
representations and agreements for the purpose of determining whether this transaction meets the requirements of the exemptions afforded by the Securities Act and certain state securities laws. I
acknowledge that the Common Stock is subject to restrictions on transferability and may not be resold, assigned or otherwise disposed of unless they are subsequently registered under the Securities
Act and under applicable securities laws of certain states or an exemption from such registration is available. I understand that I may not sell or transfer the Common Stock until three years from the
effective date of the Registration Statement. I understand that each certificate evidencing the Common Stock will bear the legend set forth below: 

	"THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED ("ACT') OR APPLICABLE STATE LAW. THE SECURITIES
MAY NOT BE PLEDGED, SOLD, ASSIGNED OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT WITH RESPECT THERETO UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAW, OR UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL, SATISFACTORY TO
THE COMPANY, THAT SUCH REGISTRATION IS NOT REQUIRED."
	

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE PROVISIONS OF A SUBSCRIPTION AGREEMENT BETWEEN THE HOLDER HEREOF AND THE COMPANY, A COPY OF WHICH IS ON FILE IN THE PRINCIPAL OFFICES OF THE COMPANY."

        7.6.    No Market for the Common Stock.    I am purchasing the Common Stock for my own account
for investment and not with a view to, or for sale in connection with, any subsequent distribution of the Common Stock, nor with any present intention of selling or otherwise disposing of all or any
part of the Common Stock. I understand that there is a currently no market for the Common Stock and there may not be any market for the Common Stock in the future. I agree that (i) the purchase
of the Common Stock is a long-term investment; (ii) I may have to bear the economic risk of investment for an indefinite period of time because the Common Stock has not been
registered under the Securities Act and may never be registered and, cannot be resold, pledged, assigned, or otherwise disposed of unless they are subsequently registered under the Securities Act and
under applicable securities laws of certain states or an exemption from such registration is available; and (iii) the Common Stock will not be transferable until three years from the effective
date of the Registration Statement, at which time the Common Stock will be released from escrow. The Common Stock may be released from escrow earlier in the event of a liquidation of the Company
following a business combination or the closing of a transaction resulting in the stockholders having the right to exchange their Common Stock for cash or other securities.

        7.7.    Entity Authority.    

        (a)   If
the Investor is a corporation, partnership, company, trust, employee benefit plan, individual retirement account, Keogh Plan, or other tax-exempt entity,
it is authorized and qualified to become an investor in the Company and the person signing this Subscription Agreement on behalf of such entity has been duly authorized by such entity to do so. 

        (b)   The
undersigned represents and Common Stock to the Company that (i) if an entity, its principal place of business and executive offices are located in the State
set forth on the Signature Page for Entity Investors and (ii) if an individual, his or her state of residency is the State set forth on the Signature Page for Individual Investors.

SECTION 7.7.  

        7.8.    No Offer Until Determination of Suitability.    I acknowledge that any delivery to me
of the documents relating to the Private Placement prior to the determination by the Company of my suitability will not constitute an offer of the Common Stock until such determination of suitability

regulations or decree, ruling or judgment of any United States or state court applicable to the Company or its property. 

        9.    Indemnification.    I hereby agree to indemnify and hold harmless the Company, its
respective officers, directors, stockholders, employees, agents, and attorneys against any and all losses, claims, demands, liabilities, and expenses (including reasonable legal or other expenses

indemnified party in any action or proceeding between the indemnitor and indemnified party or between the indemnified party and any third party) to which any such indemnified party may become subject,
insofar as such losses, claims, demands, liabilities and expenses (a) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact made by me and contained herein, or (b) arise out of or are based upon any breach by me of any representation, warranty, or agreement made by me contained herein.

$                        (the "Warrants"). Each Warrant shall entitle the

        2.    Terms of the Warrants; Warrant Agreement.    The terms of the Warrants are as set forth
in the form of Warrant Agreement attached hereto as Exhibit A. The shares of Common Stock underlying the Warrants are referred to herein as the

which the Company, in its sole discretion, shall determine to extend this offering. 

        5.    Investor Delivery of Payment and Documents.

        8.2.    Information About the Company.

services sector. I have also been given an opportunity to obtain any additional relevant information to the extent reasonably available to the Company. I have received all information regarding the
Company that I have reasonably requested. I understand that there is no assurance as to the future performance of the Company and that the Company may never effectuate a business combination. For
purposes of this Agreement, a "business combination" means, following the Public Offering (the net proceeds of which shall be deposited in a trust

trust account. 

        (b)   I
have read and fully understand the terms of the Warrant as set forth in the Warrant Agreement. 

        8.3.    No assurances; No general solicitation.    I have received no representation or warranty from the Company or
any of its officers, directors, employees or agents in respect of my investment in the Company. I am not participating in the Private Placement as a result of or subsequent to: (i) any
advertisement, article, notice or other communication published in any newspaper, magazine or similar media or broadcast over television, radio or the Internet or (ii) any seminar or meeting
whose attendees have been invited by any general solicitation or general advertising.

        8.4.    Speculative Investment.    I am aware that my purchase of the Warrants is a speculative investment. I
acknowledge that I can lose the entire amount of my investment in the Company. I have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and
risks of an investment in the Warrants and have obtained, in my judgment, sufficient information from the Company to evaluate the merits and risks of an investment in the Company. I have not utilized
any person as my purchaser representative (as defined in Regulation D promulgated under the Securities Act) in connection with evaluating such merits and risks and have relied solely upon my
own investigation in making a decision to invest in the Company. I have been urged to seek independent advice from my professional advisors relating to the suitability of an investment in the Company
in view of my overall financial needs and with respect to the legal and tax implications of such investment. I believe that the investment in the Company represented by my purchase of the Warrants in
the Private Placement is suitable for me based upon my investment objectives and financial needs, and I have adequate means for providing for my current financial needs and contingencies and have no
need for liquidity with respect to my investment in the Company. My investment in the Company does not constitute all, or substantially all, of my investment portfolio. 

        8.5.    Restrictions on Transfer.    I understand that (i) the Warrants (and the Warrant Shares) have not been
registered under the Securities Act or the securities laws of certain states in reliance on specific exemptions from registration, (ii) no securities administrator of any state or the federal
government has recommended or endorsed this Private Placement or made any finding or determination relating to the fairness of an investment in the Company and (iii) the Company is relying on
my representations and agreements for the purpose of determining whether this transaction meets the requirements of the exemptions afforded by the Securities Act and certain state securities laws. I
acknowledge that the Warrants are (and the Warrant Shares, when issued, will be) subject to restrictions on transferability and may not be resold, assigned or otherwise disposed of unless they are
subsequently registered under the Securities Act and under applicable securities laws of certain states or an exemption from such registration is available. I understand that I may not sell or
transfer the Warrants until ninety (90) days after the consummation of a business combination. I understand that each certificate evidencing each of the Warrants and the Warrant Shares will
bear the legend set forth below: 

	

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED ("ACT') OR APPLICABLE STATE LAW. THE SECURITIES MAY NOT BE PLEDGED, SOLD,
ASSIGNED OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT WITH RESPECT THERETO UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAW, OR UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY, THAT SUCH
REGISTRATION IS NOT REQUIRED."
	

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE PROVISIONS OF A SUBSCRIPTION AGREEMENT BETWEEN THE HOLDER HEREOF AND THE COMPANY, A COPY OF WHICH IS ON FILE IN THE PRINCIPAL OFFICES OF THE COMPANY."

        8.6.    No Market for the Common Stock and Warrants.    I am purchasing the Warrants for my
own account for investment and not with a view to, or for sale in connection with, any subsequent distribution of the Warrants, nor with any present intention of selling or otherwise disposing of all
or any part of the Warrants. I understand that there is a currently no market for the Common Stock or Warrants and there may not be any market for the Common Stock or Warrants in the future. I agree
that (i) the purchase of the Warrants is a long-term investment; (ii) I may have to 

3

 

bear
the economic risk of investment for an indefinite period of time because the Warrants have not been registered under the Securities Act and may never be registered and, cannot be resold, pledged,
assigned, or otherwise disposed of unless they are subsequently registered under the Securities Act and under applicable securities laws of certain states or an exemption from such registration is
available; and (iii) the Warrants cannot be resold until ninety (90) days after the consummation of a business combination. 

        8.7.    Entity Authority.    

        (a)   If
the Investor is a corporation, partnership, company, trust, employee benefit plan, individual retirement account, Keogh Plan, or other tax-exempt entity,
it is authorized and qualified to become an investor in the Company and the person signing this Subscription Agreement on behalf of such entity has been duly authorized by such entity to do so. 

        (b)   The
undersigned represents and warrants to the Company that (i) if an entity, its principal place of business and executive offices are located in the State set
forth on the Signature Page for Entity Investors and (ii) if an individual, his or her state of residency is the State set forth on the Signature Page for Individual Investors. 

        8.8.    Accredited Investor Status for Individuals.    (INVESTORS THAT ARE CORPORATIONS, LIMITED LIABILITY COMPANIES,
PARTNERSHIPS, REVOCABLE TRUSTS, IRREVOCABLE TRUSTS, EMPLOYEE BENEFIT PLAN TRUSTS AND INDIVIDUAL RETIREMENT ACCOUNTS SHOULD IGNORE THE FOLLOWING QUESTIONS AND PROCEED TO SECTION 8.9).

CONFIRMATION AT THE END OF SECTION 8.8.

        8.10.    No Offer Until Determination of Suitability.    I acknowledge that any delivery to me of the documents
relating to the Private Placement prior to the determination by the Company of my suitability will not constitute an offer of the Warrants until such determination of suitability is made. 

        9.    Company Representations and Warranties.    The Company hereby represents and warrants to
the Investor that the Company has all necessary corporate power and authority to enter into this Subscription Agreement and to consummate the transactions contemplated hereby. All corporate action
necessary to be taken by the Company to authorize the execution, delivery and performance of this Subscription Agreement and all other agreements and instruments delivered by the Company in connection
with the transactions contemplated hereby has been duly and validly taken and this Subscription Agreement has been duly executed and delivered by the Company. Subject to the terms and conditions of
this Subscription Agreement, the Subscription Agreement constitutes the valid, binding and enforceable obligation of the Company, enforceable in accordance with its terms, except as enforceability may
be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or similar laws of general application now or hereafter in effect affecting the rights and
remedies of creditors and by general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity); and (ii) the applicability of the federal and state
securities laws and public policy as to the enforceability of the indemnification provisions of this Subscription Agreement. The sale by the Company of the Warrants does not conflict with the
certificate of incorporation or by-laws of the Company or any material contract by which the Company or its property is bound, or any federal or state laws or regulations or decree, ruling
or judgment of any United States or state court applicable to the Company or its property. 

        10.    Indemnification.    I hereby agree to indemnify and hold harmless the Company, its
respective officers, directors, stockholders, employees, agents, and attorneys against any and all losses, claims, demands, liabilities, and expenses (including reasonable legal or other expenses
incurred by each such person in connection with defending or investigating any such claims or liabilities, whether or not resulting in any liability to such person or whether incurred by the
indemnified party in any action or proceeding between the indemnitor and indemnified party or between the indemnified party and any third party) to which any such indemnified party may become subject,
insofar as such losses, claims, demands, liabilities and expenses (a) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact made by me and contained
herein, or (b) arise out of or are based upon any breach by me of any representation, warranty, or agreement made by me contained herein. 

        11.    Severability; Remedies.    In the event any parts of this Subscription Agreement are
found to be void, the remaining provisions of this Subscription Agreement are nevertheless binding with the same effect as though the void parts were deleted. 

        12.    Governing Law and Jurisdiction.    This Subscription Agreement will be deemed to have
been made and delivered in New York City and will be governed as to validity, interpretation, construction, effect and in all other respects by the internal laws of the State of New York. Each of the
Company and the Investor hereby (i) agrees that any legal suit, action or proceeding arising out of or relating to this Subscription Agreement will be instituted exclusively in New York State
Supreme Court, County of New York, or in the United States District Court for the Southern District of New York, (ii) waives any objection to the venue of any such suit, action or proceeding
and the right to assert that such forum is not a convenient forum for such suit, action or proceeding, (iii) irrevocably consents to the jurisdiction of the New York State Supreme Court, County
of New York, and the United States District Court for the Southern District of New York in any such suit, action or proceeding, (iv) agrees to accept and 

10

 

acknowledge
service of any and all process that may be served in any such suit, action or proceeding in New York State Supreme Court, County of New York or in the United States District Court for the
Southern District of New York and (v) agrees that service of process upon it mailed by certified mail to its address set forth on my signature page will be deemed in every respect effective
service of process upon it in any suit, action or proceeding. 

        13.    Counterparts.    This Subscription Agreement may be executed in one or more
counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument. The execution of this Subscription Agreement may be by actual or facsimile
signature. 

        14.    Benefit.    This Subscription Agreement is binding upon and inures to the benefit of
the parties hereto and their respective heirs, executors, personal representatives, successors and assigns. 

        15.    Notices.    All notices, offers, acceptance and any other acts under this Subscription
Agreement (except payment) must be in writing, and are sufficiently given if delivered to the addressees in person, by overnight courier service, or, if mailed, postage prepaid, by certified mail

telecopy, in each case addressed to a party. All communications to me should be sent to my preferred address on the signature page hereto. All communications to the Company should be sent to the

        16.    Oral Evidence.    This Subscription Agreement constitutes the entire agreement between
the parties with respect to the subject matter hereof and supersedes all prior oral and written agreements between the parties hereto with respect to the subject matter hereof. This Subscription
Agreement may not be changed, waived, discharged, or terminated orally, but rather, only by a statement in writing signed by the party or parties against which enforcement or the change, waiver,
discharge or termination is sought. 

        17.    Section Headings.    Section headings herein have been inserted for reference only and

warranties and agreements contained herein will survive the delivery of, and the payment for, the Warrants.
