The prospectus subject to completion in the form included in the Registration Statement at the time of the initial filing of such Registration Statement with the Commission and each such prospectus filed with the Commission from time to time until the date of the Prospectus is referred to in this Agreement as a “Preliminary Prospectus.” For purposes of this Agreement, “Free Writing Prospectus” has the meaning ascribed to it in Rule 405 of the Rules and Regulations, and “Issuer Free Writing Prospectus” shall mean each Free Writing Prospectus prepared by or on behalf of the Company or used or referred to by the Company in connection with the offering of the Common Stock. “Time of Sale Information” shall mean the most recent Preliminary Prospectus together with each Free Writing Prospectus, if any, identified in Schedule IV hereto and the information set forth in Schedule V hereto.

2. Agreements to Sell and Purchase. Upon the terms and conditions set forth herein, severally and not jointly, (i) the Company agrees to issue and sell to the Underwriters 1,250,000 Firm Shares and (ii) each Selling Stockholder agrees to sell to the Underwriters the number of Firm Shares set forth opposite its name on Schedule II hereto. Upon the basis of the representations, warranties and agreements of the Company and the Selling Stockholders herein contained, and subject to all the terms and conditions set forth herein, each Underwriter agrees, severally and not jointly, to purchase from the Company and the Selling Stockholders at a purchase price of $[•] per Share (the “purchase price per Share”) the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto.

If any Additional Shares are to be purchased, each Underwriter, severally and not jointly, agrees to purchase the number of Additional Shares (subject to such adjustments as you may determine to avoid fractional shares) that bears the same proportion to the total number of Additional Shares to be purchased by the Underwriters as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto bears to the total number of Firm Shares. The option to purchase Additional Shares may be exercised in whole or in part at any time or from time to time within 30 days after the date of the Prospectus. In the event and to the extent that the Underwriters exercise their option to purchase Additional Shares, the Underwriters shall purchase such Additional Shares from each Selling Stockholder in the same proportion that the number of Firm Shares sold by each Selling Stockholder bears to the total number of Firm Shares sold by the Selling Stockholders.

It is further understood and agreed that up to [•] Firm Shares, or [•]% of the Firm Shares to be purchased by the Underwriters (the “Directed Shares”), will initially be reserved by the several Underwriters for offer and sale upon the terms and conditions to be set forth in the most recent Preliminary Prospectus and in accordance with the rules and regulations of the Financial Industry Regulatory Authority (“FINRA”) to certain officers, directors, employees and consultants of the Company and certain other persons associated with the Company (each such person a “Directed Share Participant”) who have heretofore delivered to ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Associates, Inc. offers to purchase Firm Shares in form satisfactory to ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Associates, Inc.

(f) The Company will retain in accordance with the Act and the Rules and Regulations all Issuer Free Writing Prospectuses not required to be filed pursuant to the Act and the Rules and Regulations; and if at any time after the date hereof any events shall have occurred as a result of which any Issuer Free Writing Prospectus, as then amended or supplemented, would conflict with the information in the Registration Statement, the most recent Preliminary Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or, if for any other reason it shall be necessary to amend or supplement any Issuer Free Writing Prospectus, to notify you and, upon your request, to file such document (if required to be filed by the Act) and to prepare and furnish without charge to each Underwriter as many copies as they may from time to time reasonably request of an amended or supplemented Issuer Free Writing Prospectus that will correct such conflict, statement or omission or effect such compliance.

- 7 -

you may request for the distribution of the Shares, the Company will deliver to each Underwriter and each dealer, without charge, as many copies of the Prospectus and the Time of Sale Information (and of any amendment or supplement thereto) as they may reasonably request. The Company consents to the use of the Prospectus and the Time of Sale Information (and of any amendment or supplement thereto) by the several Underwriters and by all dealers to whom Shares may be sold in accordance with the provisions of the Act, the Rules and Regulations and the securities or Blue Sky laws of the jurisdictions in which the Shares are offered, both in connection with the offering and sale of the Shares and for such period of time thereafter as the Prospectus is required by the Act and the Rules and Regulations to be delivered in connection with sales by any Underwriter or dealer. If at any time prior to the later of (i) the completion of the distribution of the Shares pursuant to the offering contemplated by the Registration Statement and (ii) the expiration of prospectus delivery requirements with respect to the Shares under Section 4(3) of the Act and Rule 174 of the Rules and Regulations, any event shall occur that in the judgment of the Company or in the reasonable opinion of counsel for the Underwriters is required to be set forth in the Prospectus (as then amended or supplemented) or should be set forth therein in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary to supplement or amend the Prospectus to comply with the Act, the Rules and Regulations or any other applicable law, the Company will prepare and, subject to Section 5(a) hereof, file with the Commission and use its commercially reasonable efforts to cause to become effective as promptly as possible an appropriate supplement or amendment thereto, and will furnish to each Underwriter who has previously requested Prospectuses, without charge, a reasonable number of copies thereof.

In the event that the qualification of the Shares in any jurisdiction is suspended, the Company shall so advise you promptly in writing.

(j) The Company will make generally available to its security holders a consolidated earnings statement (in form complying with the provisions of Rule 158), which need not be audited, covering a 12-month period commencing after the Effective Date and ending not later than 16 months thereafter, as soon as reasonably practicable after the end of such period, which consolidated earnings statement shall satisfy the provisions of Section 11(a) of the Act.

(k) During the period ending five years from the date hereof, the Company will furnish to you and, upon your request, to each of the other Underwriters, (i) as soon as practicable, a copy of each proxy statement, quarterly or annual report or other report of the Company mailed to stockholders or filed with the Commission, FINRA, the Nasdaq Stock

- 30 -

If the indemnification provided for in this Section 10 is unavailable or insufficient for any reason whatsoever to an indemnified party in respect of any Damages referred to herein, then an indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Damages (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters on the other hand, from the offering and sale of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative and several fault of the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters on the other hand, in connection with the statements or omissions that resulted in such Damages as well as any other relevant equitable considerations. The relative and several benefits received by the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering (after deducting underwriting discounts and commissions, but before expenses) received by the Company and the Selling Stockholders bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus; provided that in the event that the Underwriters shall have purchased any Additional Shares hereunder, any determination of the relative benefits received by the Company and the Selling Stockholders or the Underwriters from the offering of the Shares shall include the net proceeds (after deducting underwriting discounts and commissions, but before expenses) received by the Company and the Selling Stockholders, and the underwriting discounts and commissions received by the Underwriters, from the sale of such Additional Shares, in each case computed on the basis of the respective amounts set forth in the notes to the table on the cover page of the Prospectus. The relative fault of the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Stockholders, on the one hand, or by the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company , the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 10 was determined by a pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the Damages referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 10 are several in proportion to the respective numbers of Firm Shares set forth opposite their names in Schedule I hereto (or such numbers of Firm Shares increased as set forth in Section 13 hereof) and not joint.

Any Damages for which an indemnified party is entitled to indemnification or contribution under this Section 10 shall be paid by the indemnifying party to the indemnified party as Damages are incurred after receipt of reasonably itemized invoices therefor. The indemnity, contribution and reimbursement agreements contained in this Section 10 and the several, and not joint, representations and warranties of the Company and the Selling Stockholders set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter, its directors, officers, employees and agents, any person controlling such Underwriter, any Participating Affiliate of such Underwriter, the Company, the Selling Stockholders, their respective directors, officers, managers or members who sign the Registration Statement or any person controlling the Company or the Selling Stockholders, (ii) acceptance of any Shares and payment therefor hereunder and (iii) any termination of this Agreement.

The Company shall

If any of the conditions hereinabove provided for in this Section 11 shall not have been satisfied when and as required by this Agreement, this Agreement may be terminated by you by notifying the Company of such termination in writing or by telegram at or prior to such Closing Date, but you shall be entitled to waive any of such conditions.

12. Effective Date of Agreement. This Agreement shall become effective upon the later of (a) the execution and delivery hereof by the parties hereto and (b) release of notification of the effectiveness of the Registration Statement by the Commission; provided, however, that the provisions of Sections 9 and 10 hereof shall at all times be effective.

13. Defaulting Underwriters. If any one or more of the Underwriters shall fail or refuse to purchase Firm Shares that it or they have agreed to purchase hereunder, and the aggregate number of Firm Shares that such

- 35 -

defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Firm Shares, each non-defaulting Underwriter shall be obligated, severally, in the proportion in which the number of Firm Shares set forth opposite its name in Schedule I hereto bears to the aggregate number of Firm Shares set forth opposite the names of all non-defaulting Underwriters or in such other proportion as you may specify in the Agreement Among Underwriters, to purchase the Firm Shares that such defaulting Underwriter or Underwriters agreed, but failed or refused to purchase. If any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares and arrangements satisfactory to you and the Company for the purchase of such Firm Shares are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case that does not result in termination of this Agreement, either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven (7) days, in order that the required changes, if any, in the Registration Statement and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any such default of any such Underwriter under this Agreement. The term “Underwriter” as used in this Agreement includes, for all purposes of this Agreement, any party not listed in Schedule I hereto who, with the approval of the Representatives and the Company, purchases Shares that a defaulting Underwriter is obligated, but fails or refuses, to purchase.

14. Termination of Agreement. This Agreement shall be subject to termination in your absolute discretion, without liability on the part of any Underwriter to the Company, by notice to the Company if, prior to the Closing Date or Additional Closing Date (if different from the Closing Date and then only as to the Additional Shares), as the case may be, in your sole judgment, (i) trading in the Common Stock shall have been suspended by the Commission or the NASDAQ, (ii) trading in securities generally on the New York Stock Exchange or NASDAQ shall have been suspended or materially limited, or minimum or maximum prices shall have been generally established on such exchange, or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed upon trading in securities generally by any such exchange or by order of the Commission or any court or other governmental authority, (iii) a general moratorium on commercial banking activities shall have been declared by either federal or New York State authorities, (iv) any downgrading shall have occurred in the rating accorded the Company’s debt securities by any “nationally recognized statistical rating organization”, as that term is defined by the Commission for purposes of Rule 436(g)(2) of the Rules and Regulations, (v) any such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s debt securities or (vi) there shall have occurred any outbreak or escalation of hostilities or other international or domestic calamity, crisis or change in political, financial or economic conditions or other material event the effect of which on the financial markets of the United States is such as to make it, in your judgment, impracticable or inadvisable to market the Shares or to enforce contracts for the sale of the Shares. Notice of such cancellation shall be promptly given to the Company and its counsel by telegraph, telecopy or telephone and shall be subsequently confirmed by letter.

- 36 -

15. Failure of One or More of the Selling Stockholders to Sell and Deliver the Shares. If one or more of the Selling Stockholders shall fail to sell and deliver to the Underwriters the Shares to be sold and delivered by such Selling Stockholders on the Closing Date or Additional Closing Date, as the case may be, pursuant to this Agreement, then the Underwriters may at their option, by written notice from the Representatives to the Company and the Selling Stockholders, either (i) terminate this Agreement without any liability on the part of any Underwriter or, except as provided in Sections 9 and 10 hereof, the Company or the Selling Stockholders or (ii) purchase the Shares that the Company and other Selling Stockholders have agreed to sell and deliver in accordance with the terms hereof. If one or more of the Selling Stockholders shall fail to sell and deliver to the Underwriters the Shares to be sold and delivered by such Selling Stockholders pursuant to this Agreement on the Closing Date or Additional Closing Date, as the case may be, then the Underwriters shall have the right, by written notice from the Representatives to the Company and the Selling Stockholders, to postpone the Closing Date or Additional Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected.

16. Information Furnished by the Underwriters. The Underwriters severally confirm and the Company acknowledges and agrees that (i) the list of Underwriters and their respective participation in the sale of Shares, (ii) the concession figure set forth in the fourth paragraph and (iii) the information set forth under the sub-captions “Stabilization,” “Discretionary Accounts,” “Conflicts of Interest” and “Electronic Prospectus,” in each case under the caption “Underwriting” in the most recent Preliminary Prospectus and the Prospectus, constitute the only information concerning the Underwriters furnished by or on behalf of the Underwriters through you or on your behalf expressly for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto.

17. Miscellaneous. Except as otherwise provided in Sections 5, 6 and 14 hereof, notice given pursuant to any of the provisions of this Agreement shall be in writing and shall be delivered

18. No Fiduciary Duty. Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by any of the Underwriters, each of the Company and the Selling Stockholders acknowledges and agrees that (i) nothing herein shall create a fiduciary or agency relationship between the Company or the Selling Stockholders, on the one hand, and the Underwriters, on the other hand; (ii) the Underwriters have been retained solely to act as underwriters and are not acting as advisors, expert or otherwise, to either the Company or the Selling Stockholders in connection with this offering, the sale of the Shares or any other services the Underwriters may be deemed to be providing hereunder, including, without limitation, with respect to the public offering price of the Shares; (iii) the relationship between the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other hand, is entirely and solely commercial, and the price of the Shares was established by the Company, the Selling Stockholders and the Underwriters based on discussions and arms’ length negotiations and each of the Company and the Selling Stockholders understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (iv) any duties and obligations that the Underwriters may have to the Company or the Selling Stockholders shall be limited to those duties and obligations specifically stated herein; and (v) notwithstanding anything in this Agreement to the contrary, each of the Company and the Selling Stockholders acknowledges that the Underwriters may have financial interests in the success of the offering that are not limited to the difference between the price to the public and the purchase price delivered to the Company and the Selling Stockholders by the Underwriters for the Shares and that such interests may differ from the interests of the Company and the Selling Stockholders, and the Underwriters have no obligation to disclose, or account to the Company or the Selling Stockholders for any benefit that they may derive from, such additional financial interests. Each of the Company and the Selling Stockholders hereby waives and releases, to the fullest extent permitted by applicable law, any claims that the Company or the Selling Stockholders may have against the Underwriters with respect to any breach or alleged breach of fiduciary duty and agree that the Underwriters shall have no liability (whether direct or indirect) to the Company or the Selling Stockholders in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company or the Selling Stockholders or any of their respective members, managers, employees or creditors.

19. Research Analyst Independence. The Company and the Selling Stockholders acknowledge that (a) the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies and (b) the Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company, the value of the Common Stock and/or the offering that differ from the views of their respective investment banking divisions. The Company and the Selling Stockholders hereby waive and release, to the fullest extent permitted by law, any claims that they may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by the Underwriters’ independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company, the Selling Stockholders or their affiliates by any Underwriter’s investment banking division. The Company and the Selling Stockholders acknowledge that each of the Underwriters is a full service securities firm and as such, from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or

- 39 -

short positions in debt or equity securities of the companies that are the subject of the transactions contemplated by this Agreement.

20. Applicable Law; Counterparts. This Agreement shall be governed by and construed in accordance with the laws of the State of New York without reference to choice of law principles thereunder.

This Agreement may be signed in various counterparts, which together shall constitute one and the same instrument.

The Company, the Selling Stockholders and the Underwriters each hereby irrevocably waive any right they may have to a trial by jury in respect to any claim based upon or arising out of this Agreement or the transactions contemplated hereby.

Re:

Great White Energy Services, Inc. - Restriction on Stock Sales

Ladies and Gentlemen:

This letter is delivered to you pursuant to the Underwriting Agreement (the “Underwriting Agreement”) entered or to be entered into by and among Great White Energy Services, Inc., a Delaware corporation (the “Company”), certain stockholders of the Company named in Schedule II thereto (the “Selling Stockholders”) and ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Associates, Inc. and ▇▇▇▇▇▇▇▇▇ & Company, Inc. as the representatives (the “Representatives”) of the several underwriters (the “Underwriters”) named in Schedule I thereto. Upon the terms and subject to the conditions of the Underwriting Agreement, the Underwriters intend to effect a public offering of the common stock, par value $0.01 per share, of the Company (the “Common Stock”), as described in and contemplated by the registration statement of the Company on Form S-1, File No. 333-172174 (the “Registration Statement”), as filed with the Securities and Exchange Commission on [•], 2011 (the “Offering”).

The undersigned recognizes that it is in the best financial interests of the undersigned, as an officer or director of the Company, or an owner of Common Stock, options, warrants or other securities of the Company convertible into or exercisable for Common Stock (the “Company Securities”), that the Company complete the proposed Offering.

The undersigned further recognizes that the Company Securities held by the undersigned are, or may be, subject to certain restrictions on transferability, including those imposed by United States federal securities laws. Notwithstanding these restrictions, the undersigned has agreed to enter into this letter agreement to further assure the Underwriters that the Company Securities of the undersigned, now held or hereafter acquired, will not enter the public market at a time that might impair the underwriting effort.

Therefore, as an inducement to the Underwriters to execute the Underwriting Agreement, the undersigned hereby acknowledges and agrees that the undersigned will not, for a period commencing on the date hereof and ending 180 days after the date of the Prospectus first filed pursuant to Rule 424(b) of the Rules and Regulations, inclusive (the “Lock-Up Period”), without the prior written consent of ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Associates, Inc., (i) offer, sell, contract to sell, pledge or otherwise dispose of (each, a “Disposition”) any Company Securities, or any securities

A-1

convertible into or exercisable or exchangeable for, or rights to purchase or otherwise acquire, any Company Securities, held by the undersigned or acquired by the undersigned after the date hereof, or that may be deemed to be beneficially owned by the undersigned (collectively, the “Lock-Up Shares”), pursuant to the rules and regulations (the “Rules and Regulations”) promulgated under the Securities Act of 1933, as amended (the “Act”), and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), (ii) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such Company Securities, whether any transaction described in the foregoing clauses (i) or (ii) is to be settled by delivery of Company Securities or other securities, in cash or otherwise, (iii) exercise or seek to exercise or effectuate in any manner any rights of any nature that the undersigned has or may have hereafter to require the Company to register under the Act the undersigned’s sale, transfer or other disposition of any of the Lock-Up Shares or Company Securities held by the undersigned, or to otherwise participate as a selling securityholder in any manner in any registration effected by the Company under the Act, including under the Registration Statement, or (iv) publicly announce the intention to do any of the foregoing. Notwithstanding the foregoing, if (A) during the last 17 days of the Lock-Up Period, the Company issues an earnings release or announces material news or a material event relating to the Company occurs or (B) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then the restrictions imposed in this letter agreement shall continue to apply until the expiration of the 18-day period beginning on the date of issuance of the earnings release or the announcement of the material news or the occurrence of the material event; provided that such extension shall not apply if (x) at the expiration of the Lock-Up Period, the Company Securities are “actively traded securities” (as defined in Regulation M under the Exchange Act) and (y) the Company meets the applicable requirements of paragraph (a)(1) of Rule 139 under the Act, in the manner contemplated by NASD Rule 2711(f)(4) of the FINRA Manual. The foregoing restrictions are expressly agreed to preclude the undersigned from engaging in any hedging, collar (whether or not for any consideration) or other transaction that is designed to or may reasonably be expected to lead to or result in a Disposition of Lock-Up Shares during the Lock-Up Period, even if such Lock-Up Shares would be disposed of by someone other than such holder. Such prohibited hedging or other transactions would include any short sale or any purchase, sale or grant of any right (including any put or call option or reversal or cancellation thereof) with respect to any Lock-Up Shares or with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from Lock-Up Shares.

Notwithstanding the agreement not to make any Disposition during the Lock-Up Period, you have agreed that the foregoing restrictions shall not apply to:

(1)

the Company Securities being offered in the prospectus included in the Registration Statement;

(2)

any grant or exercise of options pursuant to the Company’s 2011 Equity Incentive Plan;

(3)

transactions related to the Company Securities acquired in open market transactions after the completion of the Offering, provided that no filing under

A-2

Section 16 of the Exchange Act, other than a Form 5, will be required or will be voluntarily made in connection with the subsequent sales of Company Securities acquired in such open market transactions during the Lock-Up Period;

(4)

transfers as a bona fide gift or gifts;

(5)

transfers to a family member, trust, family limited partnership or family limited liability company for the direct or indirect benefit of the undersigned or his or her family member;

(6)

transfers by testate or intestate succession; or

(7)

if the undersigned is an entity, transfers to the limited partners, members or stockholders as part of a distribution, or to any corporation, partnership or other business that is its affiliate;

The statements in the Prospectus and the Time of Sale Information under the captions “Description of Capital Stock” and “Shares Eligible for Future Sale,” insofar as such statements constitute a summary of the documents referred to therein, matters of law or legal proceedings, fairly present in all material respects the information required to be shown and are fair and accurate summaries.

Negative Assurance

Because the primary purpose of such counsel’s professional engagement was not to establish or confirm factual matters or financial, accounting, statistical or reserve information, and because many determinations involved in the preparation of the Registration Statement, the

B-3

Time of Sale Information or the Prospectus are of a wholly or partially non-legal character, except as set forth in paragraphs 11, 14 and 16 of this letter, such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus and such counsel makes no representation that it has independently verified the accuracy, completeness or fairness of such statements.

However, in the course of such counsel’s acting as counsel to the Company in connection with its preparation of the Registration Statement, the Time of Sale Information and the Prospectus, prior to the filing of the Registration Statement, the Preliminary Prospectus and the Prospectus, such counsel participated in conferences and telephone conversations with representatives of the Company, representatives of the independent public accountants for the Company, representatives of the Selling Stockholders, representatives of the Underwriters and representatives of the Underwriters’ counsel, during which conferences and conversations the contents of the Registration Statement, the Time of Sale Information and the Prospectus and related matters were discussed, and such counsel reviewed certain corporate records and documents furnished to such counsel by the Company and certain documents publicly filed by the Company with the Commission.

Subject to the foregoing, such counsel confirms to you that, on the basis of the information we gained in the course of performing the services referred to above:

(a)

Each of the Registration Statement, the Time of Sale Information and the Prospectus, and each amendment or supplement thereto, including the documents incorporated by reference therein, in each case as of their respective effective or issue dates appeared on its face, as supplemented or amended, to be appropriately responsive in all material respects to the requirements of the Securities Act and the applicable rules and regulations thereunder, except that (i) we express no view as to the financial statements and related notes and schedules or other financial data, accounting data [or reports on the effectiveness of internal control over financial reporting], or statistical data derived from such financial data contained in or omitted from the Registration Statement, the Time of Sale Information or the Prospectus and (ii) we express no view of the anti-fraud provisions of the U.S. securities Laws and the rules and regulations promulgated under such provisions; and

(b)

No facts have come to our attention that cause us to believe that:

(i)

the Registration Statement, at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

(ii)

the Time of Sale Information, as of the Time of Sale, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

B-4

(iii)

the Prospectus, as of its date and as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; except that in the case of each of clauses (i) – (iii) above, such counsel does not express any view as to the financial statements and related notes and schedules or other financial data, accounting data [or reports on the effectiveness of internal control over financial reporting], or statistical data derived from such financial data contained in or omitted from the Registration Statement, the Time of Sale Information or the Prospectus.

Included Laws

We express no opinion as to the laws of any jurisdiction other than the Included Laws. We have made no special investigation or review of any published constitutions, treaties, laws, rules or regulations or judicial or administrative decisions (“Laws”), other than a review of (i) the DGCL, (ii) the Federal securities Laws of the United States of America and (iii) the NY UCC. For purposes of this opinion, the term “Included Laws” means the items described in clauses (i), (ii) and (iii) of the preceding sentence that are, in our experience, normally applicable to transactions of the type contemplated in the Underwriting Agreement. The term Included Laws specifically excludes (a) Laws of any counties, cities, towns, municipalities and special political subdivisions, or foreign governments and any agencies thereof, (b) zoning, land use, building and construction Laws, (c) Federal Reserve Board margin regulations, (d) any antifraud, environmental, labor, tax, pension, employee benefit, antiterrorism, money laundering, insurance, antitrust, securities or intellectual property Laws and (e) Laws relating to the regulation of the conduct of the business of the Company and the Subsidiaries, including, without limitation, the business of oil and natural gas exploration and production companies.

The execution and delivery of the Underwriting Agreement by each Selling Stockholder, and the performance by each Selling Stockholder of its obligations thereunder, have been duly authorized by all necessary limited liability company action on the part of such Selling Stockholder. The Underwriting Agreement has been duly executed and delivered by each Selling Stockholder.

None of the sale of the Shares to be sold by the Selling Stockholders to the Underwriters pursuant to the Underwriting Agreement or the execution, delivery or performance by the Selling Stockholders of the Underwriting Agreement will (i) with or without the giving of notice or passage of time or both, conflict with or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to, any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any other agreement or instrument known to me to which such Selling Stockholder is a party or by which it is bound, (ii) result in a violation of the organizational documents of such Selling Stockholder, (iii) result in the violation of any law, rule or regulation of any Relevant Laws or (iv) result in any violation of any order, writ, judgment or decree of any governmental authority known to me and identified in a schedule to my opinion.

No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any Federal or state governmental authority or agency is required for the sale of the Shares to be sold by the Selling Stockholders to the Underwriters pursuant to the Underwriting Agreement or the due execution and delivery of the Underwriting Agreement by each Selling Stockholder and the performance by each Selling Stockholder of its respective obligations under the Underwriting Agreement except for (i) those that have been obtained or made and (ii) those that may be required under state securities laws or blue sky laws.

The opinions expressed herein are qualified in their entirety as follows: (a) no opinion is expressed with respect to laws other than the Federal laws of the United States, the laws of the State of New York, the Delaware General Corporation Law and the Limited Liability Company Act of the State of Delaware (the “Relevant Laws”); and (b) to the extent that any one or more of the foregoing opinions relates to the enforceability of any agreement or instrument: (1) the opinions are subject to the effect of applicable laws or judicial decisions regarding bankruptcy, reorganization, insolvency, fraudulent transfers, moratorium and other laws affecting creditors’ rights and debtors’ relief generally; (2) the enforceability of the provisions of any such agreement or instrument is subject to the application of principles of equity, whether in a proceeding at law or in equity, including the exercise of discretionary powers of any tribunal

C-1

before which equitable remedies may be sought (including, without limitation, specific performance and injunctive relief); and (3) the enforceability of the provisions of any such agreement or instrument in accordance with its respective terms may be limited by laws affecting the remedies which it provides, including, but not limited to, laws and judicial decisions limiting such enforceability.

The opinions expressed herein are based upon the Relevant Laws and interpretations thereof in effect on the date hereof, and the facts and circumstances in existence on the date hereof, and I assume no obligation to revise or supplement this opinion letter should any such law or interpretation be changed by legislative action, judicial decision or otherwise or should there be any change in such facts or circumstances after the date hereof.

The opinions expressed herein are matters of professional judgment, are not a guarantee of result, are effective only as of the date hereof, may not be relied upon for any other purpose and may not be furnished to or relied upon by any other person other than the addressees hereof and their successors and permitted assignees for any purpose without my prior written consent. This opinion letter is rendered as of the date hereof, and I disclaim any undertaking to advise of any changes that may hereafter be brought to my attention. I express no opinion other than as expressly set forth herein. No expansion of the opinions expressed herein may or should be made by implication or otherwise.

Each of Pressure Control and Directional Services has the corporate power or limited liability company power, as applicable, and authority to own, lease, hold and operate its properties and to conduct the business in which it is engaged as described in the Registration Statement, the Time of Sale Information and the Prospectus.

Negative Assurance

Because such counsel’s primary responsibility was not to establish or confirm factual matters or financial, accounting, statistical or reserve information, and because many determinations involved in the preparation of the Registration Statement, the Time of Sale Information or the Prospectus are of a wholly or partially non-legal character, except as set forth in paragraph 4 of this letter, such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus and such counsel makes no representation that he has independently verified the accuracy, completeness or fairness of such statements.

However, in the course of such counsel’s acting as General Counsel of the Company in connection with its preparation of the Registration Statement, the Time of Sale Information and the Prospectus, prior to the filing of the Registration Statement, the Preliminary Prospectus and the Prospectus, such counsel participated in conferences and telephone conversations with other representatives of the Company, representatives of the independent public accountants for the

Company, representatives of the Selling Stockholders, representatives of the Underwriters and representatives of the Underwriters’ counsel, during which conferences and conversations the contents of the Registration Statement, the Time of Sale Information and the Prospectus and related matters were discussed, and such counsel reviewed certain records and documents maintained by the Company and certain documents publicly filed by the Company with the Commission.

Subject to the foregoing, such counsel confirms to you that, on the basis of the information he gained in the course of performing the services referred to above, no facts have come to my attention that cause me to believe that:
