NATIONAL ENERGY RESOURCES ACQUISITION COMPANY  


 
  SPONSOR'S WARRANTS SUBSCRIPTION AGREEMENT    
    


        THIS SPONSOR'S WARRANTS SUBSCRIPTION AGREEMENT (this "Agreement") is made as of the 26th day of November, 2007, by
and between National Energy Resources Acquisition Company, a Delaware corporation (the "Company"), and NRCO LLC, a Colorado limited liability company
(the "Purchaser"). 


        WHEREAS,
the Company has filed a registration statement on Form S-1 with the Securities and Exchange Commission (the "Registration
Statement") in connection with the proposed initial public offering of the Company's units (the "IPO"), each unit consisting of
one share of the Company's common stock, par value $0.0001 per share (the "Common Stock"), and one warrant to purchase one share of Common Stock at an
exercise price of $7.50 per share; 


        WHEREAS,
the Company desires to commit to issue and sell, and the Purchaser desires to commit to purchase and acquire, Sponsor's Warrants (as defined below) on the terms and conditions
hereinafter set forth; 


        NOW,
THEREFORE, for and in consideration of the promises and mutual covenants set forth herein, it is agreed between the parties as follows: 


        1.     Commitment To Purchase Sponsor's Warrants. Subject to the terms and conditions of this Agreement, the Purchaser hereby
agrees to subscribe for and purchase from the Company, and the Company hereby agrees to issue and sell to Purchaser, an aggregate of 3,000,000 warrants (each a "Sponsor's
Warrant") at a purchase price of $1.00 per Sponsor's Warrant for an aggregate purchase price of $3,000,000 on the Closing Date (as defined below). Each Sponsor's Warrant shall
entitle the holder thereof to purchase one share of Common Stock at an exercise price of $7.50, in accordance with the terms of the Sponsor's Warrant as set forth in the Warrant Agreement entered into
by and between the Company and Computershare Trust Company, Inc., as warrant agent. The Warrant Agreement shall be substantially in the form attached hereto as Exhibit A (the
"Warrant Agreement"). The closing of the purchase and sale of the Sponsor's Warrants hereunder, including payment for and delivery of the Sponsor's
Warrants, shall occur at the offices of the Company or at such other location by mutual agreement of the parties on the Closing Date. 


        2.     Purchase and Sale of the Sponsor's Warrants. Simultaneously with, and subject to the consummation of, the IPO (the
"Closing Date"), the Company shall issue and sell to the Purchaser, and the Purchaser agrees to purchase from the Company, the respective number of
Sponsor's Warrants set forth opposite the Purchaser's name on Schedule A hereto. 



        3.     Payment of Purchase Price. The purchase price for the Sponsor's Warrants to be purchased by the Purchaser shall be
tendered in full on the Closing Date by the Purchaser, by one or a combination of the following means: 



        (a)   wiring
of immediately available United States funds to an account for the benefit of the Company, pursuant to wire instructions provided by the Company no less than two
business days prior to the Closing Date; or 


        (b)   delivery
of a cashier's check to the Company of immediately available United States funds. 




        4.     Acceptance or Rejection of Agreement. The Sponsor's Warrants subscribed for herein will not be deemed issued to or owned
by the Purchaser until a copy of this Agreement has been executed by the Company and the Purchaser, and the IPO has been consummated. 


        5.     Limitations on Transfer. Without the prior written consent of the representative of the underwriters with respect to the
IPO, Purchaser shall not, other than transfers to Permitted Transferees 







 



(as
defined in Section 5 of the Warrant Agreement) that agree in writing to be bound by the terms and conditions of the transfer restrictions set forth in this Section 5 and, if at the
time applicable, the provisions of Section 6(f) of the Warrant Agreement, (a) sell, offer to sell, contract or agree to sell, assign, hypothecate, donate, pledge, grant any
security interest in, encumber, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or
decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission
("SEC") promulgated thereunder, with respect to, the Sponsor's Warrants or the shares of Common Stock issuable upon exercise of the Sponsor's Warrants
or any securities exchangeable for the Sponsor's Warrants or other rights to purchase the Sponsor's Warrants or any such securities, (b) enter into any swap or other arrangement that transfers
to another, in whole or in part, any of the economic consequences of ownership of the Sponsor's Warrants or the shares of Common Stock issuable upon exercise of the Sponsor's Warrants or any
securities exchangeable for the Sponsor's Warrants or other rights to purchase the Sponsor's Warrants or any such securities, whether any such transaction is to be settled by delivery of Common Stock
or such other securities, in cash or otherwise, or (c) publicly announce any intention to effect any transaction specified in this Section 5(a) or (b), until the date immediately
following the date of the consummation by the Company of an initial Business Combination (as defined in Section 8 hereof). 


        6.     Registration Rights. In connection with the closing of the IPO, the Company and the Purchaser shall enter into an
agreement (the "Registration Rights Agreement") granting the Purchaser registration rights with respect to Sponsor's Warrants and the shares underlying the Sponsor's Warrants. 



        7.     Restrictive Legends. All certificates representing the Sponsor's Warrants (and any underlying securities thereof) shall
have endorsed thereon legends in substantially the following forms (in addition to any other legend which may be required by other agreements between the parties hereto): 



        (a)   "THE
SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE SECURITIES MAY NOT BE SOLD, OFFERED FOR
SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS
NOT REQUIRED." 


        (b)   "THE
SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE ASSIGNED, HYPOTHECATED, DONATED, ENCUMBERED, SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN
ACCORDANCE WITH THAT CERTAIN SPONSOR'S WARRANTS SUBSCRIPTION AGREEMENT DATED AS OF NOVEMBER 26, 2007 AND THAT CERTAIN WARRANT AGREEMENT DATED AS OF            , 2007, COPIES OF WHICH
ARE
AVAILABLE FOR INSPECTION AT THE OFFICES OF THE COMPANY." 


        (c)   Any
legend required by appropriate blue sky officials. 




        8.     Investment Representations. In connection with the purchase of the Sponsor's Warrants, the Purchaser represents to the
Company the following: 



        (a)   The
Purchaser has been furnished with all materials relating to the Company's business affairs and financial condition and materials related to the offer and sale of the
Sponsor's Warrants that have been requested by the Purchaser and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Sponsor's
Warrants. The Purchaser has been afforded the opportunity to ask questions of the executive officers and directors of the Company. The Purchaser understands that its investment in the Sponsor's
Warrants involves a high degree of risk. The Purchaser has sought such accounting, legal and tax advice as the Purchaser has considered necessary to make an informed investment decision with 



2







 

respect
to the Purchaser's acquisition of the Sponsor's Warrants. The Purchaser has such knowledge and expertise in financial and business matters, knows of the high degree of risk associated with
investments generally and particularly investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the
Sponsor's Warrants, and is able to bear the economic risk of an investment in the Sponsor's Warrants in the amount contemplated hereunder. The Purchaser has adequate means of providing for its current
financial needs and contingencies and will have no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Sponsor's Warrants. The Purchaser can afford a
complete loss of its investment in the Sponsor's Warrants. The Purchaser is purchasing the Sponsor's Warrants for investment for the Purchaser's own account only and not with a view to, or for resale
in connection with, any "distribution" thereof within the meaning of the Securities Act of 1933, as amended (the "Act"). The Purchaser understands that
the Company is a blank check development stage company recently formed for the purpose of consummating an initial business combination (a "Business
Combination") and understands that there is no assurance as to the future performance of the Company and that the Company may never effectuate a Business Combination. 


        (b)   The
Purchaser understands that the Sponsor's Warrants (and the securities underlying the Sponsor's Warrants) have not been registered under the Act or any state
securities law by reason of a specific exemption therefrom, and that the Company is relying on the truth and accuracy of, and the Purchaser's compliance with, the representations and warranties and
agreements of the Purchaser set forth herein to determine the availability of such exemptions and the eligibility of the Purchaser to acquire such Sponsor's Warrants, including, but not limited to,
the bona fide nature of the Purchaser's investment intent as expressed herein. 



        (c)   The
Purchaser further acknowledges and understands that the Sponsor's Warrants (and the securities underlying the Sponsor's Warrants) must be held indefinitely, subject
to any expiration, unless the Sponsor's Warrants (and the securities underlying the Sponsor's Warrants) are subsequently registered under the Act or an exemption from such registration is available.
The Purchaser understands that the certificates evidencing the Sponsor's Warrants (and the securities underlying the Sponsor's Warrants) will be imprinted with a legend which prohibits the transfer of
the Sponsor's Warrants (and the
securities underlying the Sponsor's Warrants) unless the Sponsor's Warrants (and the securities underlying the Sponsor's Warrants) are registered or such registration is not required in the opinion of
counsel for the Company. 


        (d)   The
Purchaser is familiar with the provisions of Rule 144 under the Act, as in effect from time to time
("Rule 144"), which, in substance, permit limited public resale of "restricted securities" acquired, directly or indirectly, from the issuer
thereof (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions. Unless the Company registers the Sponsor's Warrants (and the
securities underlying the Sponsor's Warrants) under the Act, the Sponsor's Warrants (and the securities underlying the Sponsor's Warrants) may be resold by the Purchaser only in certain limited
circumstances subject to the provisions of Rule 144, which requires, among other things: (i) the availability of certain public information about the Company and (ii) the resale
occurring following the required holding period under Rule 144 after the Purchaser has purchased, and made full payment of (within the meaning of Rule 144), the securities to be sold. 


        (e)   The
Purchaser further understands that at the time the Purchaser wishes to sell the Sponsor's Warrants there may be no public market upon which to make such a sale, and
that, even if such a public market then exists, the Company may not be satisfying the current public information requirements of Rule 144, and that, in such event, the Purchaser would be
precluded from selling the Sponsor's Warrants (and the securities underlying the Sponsor's Warrants) under Rule 144 even if the minimum holding period requirement had been satisfied.
Notwithstanding 



3







 




Sections 8(d) and
(e) hereof, the Purchaser understands that it may be considered a promoter of the Company and understands that it is the position of the SEC that promoters or
affiliates of a blank check company and their transferees, both before and after a Business Combination, would be deemed to be "underwriter" under the Act when reselling the securities of the blank
check company. Accordingly, the SEC believes that those securities can be resold only through a registered offering and that Rule 144 would not be available for those resale transactions
despite technical compliance with the requirements of Rule 144. 



        (f)    The
Purchaser represents that it is an "accredited investor" as that term is defined in Rule 501 of Regulation D promulgated by the SEC under the Act. 


        (g)   The
Purchaser has all necessary company power and authority to enter into this Agreement and to consummate the transactions contemplated hereby. All action necessary to
be taken by the Purchaser to authorize the execution, delivery and performance of this Agreement and all other agreements and instruments delivered by the Purchaser in connection with the transactions
contemplated hereby has been duly and validly taken, and this Agreement has been duly executed and delivered by the Purchaser. This Agreement constitutes the valid, binding and enforceable obligation
of the Purchaser, 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 Agreement. The purchase by the Purchaser of the Sponsor's Warrants does not conflict with the organizational documents of the Purchaser
or with any material contract by which the Purchaser or its property is bound, or any laws or regulations or decree, ruling or judgment of any court applicable to the Purchaser or its property. The
principal place of business of the Purchaser is as set forth on the signature page hereto. 


        (h)   The
Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the meaning of
Rule 502(c) of the Act. 


        (i)    The
Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or
endorsement of the Sponsor's Warrants or the fairness or suitability of the investment in the Sponsor's Warrants, nor have such authorities passed upon or endorsed the merits of the offering of the
Sponsor's Warrants. 




        9.     Company Representations and Warranties.



        (a)   The
Company hereby represents and warrants to the Purchaser that the Company has all necessary corporate power and authority to enter into this 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 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 Agreement has been duly executed and delivered by
the Company. This 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 Agreement. The sale by the Company of the Sponsor's Warrants does not conflict with the certificate of
incorporation or 



4







 

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. 


        (b)   Upon
issuance in accordance with, and payment pursuant to, the terms hereof and the Warrant Agreement, the shares issuable upon exercise of the Sponsor's Warrants will
be duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms
hereof and the Warrant Agreement, the Purchaser will have good title to the Sponsor's Warrants and the shares issuable upon exercise of such Sponsor's Warrants, will be free and clear of all liens,
claims and encumbrances of any kind, other than (i) transfer restrictions hereunder and under the other agreements contemplated hereby, (ii) transfer restrictions under federal and state
securities laws, and (iii) liens, claims or encumbrances imposed due to the actions of the applicable Purchaser.

transactions contemplated by this Agreement or the Warrant Agreement.
