As Representative of the Initial Purchasers

Ladies and Gentlemen:

Introductory. Parker Drilling Company, a Delaware corporation (the “Company”), proposes to issue and sell to the several Initial Purchasers named in Schedule A (the “Initial Purchasers”), acting severally and not jointly, the respective amounts set forth in such Schedule A of $125.0 million aggregate principal amount of the Company’s 9 1/8% Senior Notes due 2018 (the “Notes”). Barclays Capital Inc. has agreed to act as the representative of the several Initial Purchasers (the “Representative”) in connection with the offering and sale of the Notes.

The Notes are to be issued as “Additional Notes” pursuant to, and in accordance with, the provisions of an Indenture, dated as of March 22, 2010 (the “Indenture”), among the Company, the Guarantors (as defined below) and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). Certain terms of the Notes will be established pursuant to an Officers’ Certificate of the Company to be dated as of the Closing Date (as defined below) pursuant to, and in accordance with, Section 2.01 of the Indenture (the “Officers’ Certificate”). Securities (as defined below) will be issued only in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”) pursuant to a letter of representations, dated on or before the Closing Date (as defined in Section 2 hereof) (the “DTC Agreement”), among the Company, the Trustee and the Depositary.

The holders of the Notes will be entitled to the benefits of a registration rights agreement, to be dated as of the Closing Date (as defined below) (the “Registration Rights Agreement”), among the Company, the Guarantors and the Initial Purchasers, pursuant to which the Company and the Guarantors may be required to file with the Commission (as defined below), under the circumstances set forth therein, (i) a registration statement under the Securities Act (as defined below) relating to another series of debt securities of the Company with terms substantially identical to the Notes (the “Exchange Notes”) and the Guarantees (the “Exchange Guarantees”) to be offered in exchange for the Notes and the Guarantees (the “Exchange Offer”) and (ii) to the extent required by the Registration Rights Agreement, a shelf registration statement pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Notes, and in each case, to use its commercially reasonable best efforts to cause such registration statements to be declared effective. All references herein to the Exchange Notes and the Exchange Offer are only applicable if the Company and the Guarantors are in fact required to consummate the Exchange Offer pursuant to the terms of the Registration Rights Agreement.

The payment of principal of, premium, if any, and interest on the Notes will be fully and unconditionally guaranteed on a senior unsecured basis, jointly and severally by (i) the entities listed on the signature pages hereof as “Guarantors” and (ii) any subsidiary of the Company formed or acquired after the Closing Date that executes an additional guarantee in accordance with the terms of the Indenture, and their respective successors and assigns (collectively, the “Guarantors”), pursuant to their guarantees (the “Guarantees”). The Notes and the Guarantees attached thereto are herein collectively referred to as the “Securities”; and the Exchange Notes and the Exchange Guarantees attached thereto are herein collectively referred to as the “Exchange Securities.”

As described under the caption “Refinancing Transactions” in the Pricing Disclosure Package and the Final Offering Memorandum, the Company has commenced a tender offer for any and all of the Company’s outstanding 2¹/8% Convertible Senior Notes due 2012 (the “Tender Offer”).

This Agreement, the Indenture, the Securities, the Exchange Securities and the Registration Rights Agreement are referred to in this Agreement collectively as the “Transaction Documents”.

The Company understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and in the Pricing Disclosure Package (as defined below) and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (the “Subsequent Purchasers”) on the terms set forth in the Pricing Disclosure Package (the first time when sales of the Securities are made is referred to as the “Time of Sale”). The Securities are to be offered and sold to or through the Initial Purchasers without being registered with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933 (as amended, the “Securities Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder), in reliance upon exemptions therefrom. Pursuant to the terms of the Securities and the Indenture, investors who acquire Securities shall be deemed to have agreed that Securities may only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemptions afforded by Rule 144A under the Securities Act (“Rule 144A”) or Regulation S under the Securities Act (“Regulation S”)).

The Company has prepared and delivered to each Initial Purchaser copies of a Preliminary Offering Memorandum, dated April 11, 2012 (the “Preliminary Offering Memorandum”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement, dated April 11, 2012 (the “Pricing Supplement”), describing the terms of the Securities, each for use by such Initial Purchaser in connection with its solicitation of offers to purchase the Securities.

All references herein to the terms “Pricing Disclosure Package” and “Final Offering Memorandum” shall be deemed to mean and include all information filed under the Securities Exchange Act of 1934 (as amended, the “Exchange Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder) prior to the Time of Sale and

incorporated by reference in the Pricing Disclosure Package (including the Preliminary Offering Memorandum) or the Final Offering Memorandum (as the case may be), and all references herein to the terms “amend,” “amendment” or “supplement” with respect to the Final Offering Memorandum shall be deemed to mean and include all information filed under the Exchange Act after the Time of Sale and incorporated by reference in the Final Offering Memorandum.

with any provision hereof, the Company agrees to reimburse the Initial Purchasers upon demand for all out-of-pocket expenses that shall have been reasonably incurred by the Initial Purchasers in connection with the proposed purchase and the offering and sale of the Securities, including, without limitation, fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges.

SECTION 7. Offer, Sale and Resale Procedures. Each of the Initial Purchasers, on the one hand, and the Company and each of the Guarantors, on the other hand, hereby agree to observe the following procedures in connection with the offer and sale of the Securities:

(a) Offers and sales of the Securities will be made only by the Initial Purchasers or Affiliates thereof qualified to do so in the jurisdictions in which such offers or sales are made. Each such offer or sale shall only be made to persons whom the offeror or seller reasonably believes to be Qualified Institutional Buyers or non-U.S. persons outside the United States to whom the offeror or seller reasonably believes offers and sales of the Securities may be made in reliance upon Regulation S upon the terms and conditions set forth in Annex I hereto, which Annex I is hereby expressly made a part hereof.

(b) The Securities will be offered by approaching prospective Subsequent Purchasers on an individual basis. No general solicitation or general advertising (within the meaning of Rule 502 under the Securities Act) will be used in the United States in connection with the offering of the Securities.

(c) Upon original issuance by the Company, and until such time as the same is no longer required under the applicable requirements of the Securities Act, the Securities (and all securities issued in exchange therefor or in substitution thereof, other than the Exchange Securities) shall bear the legend contained in “Transfer Restrictions” in the Preliminary Offering Memorandum.

(d) Each of the Initial Purchasers represents and agrees that (i) it has only communicated or caused to be communicated and will only communicate or cause to be communicated any invitation or inducement to engage in investment activity (within the meaning of section 21 of the Financial Services and Markets Act 2000 (the “FSMA”)) received by it in connection with the issue or sale of the Securities in circumstances in which section 21(1) of the FSMA does not apply to the Company and the Guarantors; and (ii) it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the Securities in, from or otherwise involving the United Kingdom.

Following the sale of the Securities by the Initial Purchasers to Subsequent Purchasers pursuant to the terms hereof, the Initial Purchasers shall not be liable or responsible to the Company for any losses, damages or liabilities suffered or incurred by the Company, including any losses, damages or liabilities under the Securities Act, arising from or relating to any resale or transfer of any Security other than by or on behalf of such Initial Purchasers.

SECTION 8. Indemnification.

(a) Indemnification of the Initial Purchasers. Each of the Company and the Guarantors, jointly and severally, agrees to indemnify and hold harmless each Initial Purchaser, its affiliates, directors, officers and employees, and each person, if any, who controls any Initial Purchaser within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Initial Purchaser, director, officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based: (i) upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), (ii) the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) any act or failure to act or any alleged act or failure to act by any Initial Purchaser in connection with, or relating in any manner to, the Securities or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided that the Company and the Guarantors will not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Initial Purchaser through its gross negligence or willful misconduct); and to reimburse each Initial Purchaser and each such director, officer, employee or controlling person for any and all expenses (including the fees and disbursements of counsel chosen by Barclays Capital Inc.) as such expenses are reasonably incurred by such Initial Purchaser or such director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply, with respect to an Initial Purchaser, to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto). The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have.

(b) Indemnification of the Company and the Guarantors. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each Guarantor, each of their respective directors, officers and each person, if any, who controls the Company or any Guarantor within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, any Guarantor or any such director, officer or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise

(including in settlement of any litigation, if such settlement is effected with the written consent of such Initial Purchaser), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by such Initial Purchaser through the Representative expressly for use therein; and to reimburse the Company, any Guarantor and each such director, officer or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by the Company, any Guarantor or such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. Each of the Company and the Guarantors hereby acknowledges that the only information that the Initial Purchasers through the Representative have furnished to the Company expressly for use in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto) are the statements set forth in the 9th paragraph under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Final Offering Memorandum. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Initial Purchaser may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party hereunder for contribution or otherwise than under the indemnity agreement contained in this Section 8, except to the extent it is materially prejudiced (through the forfeiture of substantive rights and defenses) as a result of such failure and shall not relieve the indemnifying party from any liability that the indemnifying party may have to an indemnified party otherwise than under the provisions of this Section 8 and Section 9. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional

to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel (in each jurisdiction)), approved by the indemnifying party (Barclays Capital Inc. in the case of Sections 8(b) and 9 hereof), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which will not be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 8, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

SECTION 9. Contribution. If the indemnification provided for in Section 8 hereof is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement 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 fault of the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total discount received by the Initial Purchasers bear to the aggregate initial offering price of the Securities. The relative fault of the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Company and the Guarantors, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or inaccuracy.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8 hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8 hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8 hereof for purposes of indemnification.

The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9.

Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in excess of the discount received by such Initial Purchaser in connection with the Securities distributed by it. No person guilty of fraudulent misrepresentation (within the meaning of Section 11 of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each director, officer and employee of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director of the Company or any Guarantor, and each person, if any, who controls the Company or any Guarantor with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company and the Guarantors.

SECTION 10. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representative by notice given to the Company if at any time: (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by the NYSE; (ii) trading in securities generally on either the Nasdaq Stock Market or the NYSE shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such quotation system or stock exchange by the Commission or FINRA; (iii) a general banking moratorium shall have been declared by any of federal, New York or Delaware authorities; (iv) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representative is material and adverse and makes it impracticable or inadvisable to proceed with the offering sale or delivery of the Securities in the manner and on the terms described in the Pricing Disclosure Package or to enforce contracts for the sale of securities; (v) in the judgment of the Representative there shall have occurred any Material Adverse Change; or (vi) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representative may interfere materially with the conduct of the business and operations of the Company regardless of whether or not such loss shall have been insured. Any termination pursuant to this Section 10 shall be without liability on the part of (i) the Company or any Guarantor to any Initial Purchaser, except that the Company and the Guarantors shall be obligated to reimburse the expenses of the Initial Purchasers pursuant to Sections 4 and 6 hereof, (ii) any Initial Purchaser to the Company, or (iii) any party hereto to any other party except that the provisions of Sections 8 and 9 hereof shall at all times be effective and shall survive such termination.

SECTION 11. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Guarantors, their respective officers and the several Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser, the Company, any Guarantor or any of their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

The term “successors” shall not include any Subsequent Purchaser or other purchaser of the Securities as such from any of the Initial Purchasers merely by reason of such purchase.

SECTION 14. Authority of the Representative. Any action by the Initial Purchasers hereunder may be taken by Barclays Capital Inc. on behalf of the Initial Purchasers, and any such action taken by Barclays Capital Inc, shall be binding upon the Initial Purchasers.

SECTION 15. Partial Unenforceability.

SECTION 16. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE.

SECTION 17. Default of One or More of the Several Initial Purchasers. If any one or more of the several Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportions that the number of Securities set forth opposite their respective names on Schedule A bears to the aggregate number of Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing Date. If any one or more of the Initial Purchasers shall fail or refuse to purchase Securities and the aggregate number of Securities with respect to which such default occurs exceeds 10% of the aggregate number of Securities to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Company for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination. In any such case either the Initial Purchasers or the Company shall have the right to postpone the 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 Final Offering Memorandum or any other documents or arrangements may be effected.

As used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 17. Any action taken under this Section 17 shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

SECTION 18. No Advisory or Fiduciary Responsibility. Each of the Company and the Guarantors acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Guarantors, on the one hand, and the several Initial Purchasers, on the other hand, and the Company and the Guarantors are capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Initial Purchaser is and has been acting solely as a principal and is not the agent or fiduciary of the Company, and the Guarantors or their respective affiliates, stockholders, creditors or employees or any other party; (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Company and the Guarantors with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Company and the Guarantors on other matters) or any other obligation to the Company and the Guarantors except the obligations expressly set forth in this Agreement; (iv) the several Initial Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the Guarantors and that the several Initial Purchasers have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship;

and (v) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company and the Guarantors have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Guarantors and the several Initial Purchasers, or any of them, with respect to the subject matter hereof. The Company and the Guarantors hereby waive and release, to the fullest extent permitted by law, any claims that the Company and the Guarantors may have against the several Initial Purchasers with respect to any breach or alleged breach of fiduciary duty.

SECTION 19. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile or other electronic transmission (i.e., a “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart thereof. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to the Company the enclosed copies hereof, whereupon this instrument, along with all counterparts hereof, shall become a binding agreement in accordance with its terms.

Very truly yours,

EXHIBIT A

[Form of Baker Botts L.L.P. Opinion]

Each of the Company and the Delaware Guarantor is a corporation validly existing corporation in good standing under the laws of the State of Delaware. The Company has all requisite corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Pricing Disclosure Package and the Final Offering Memorandum and to execute and deliver the Purchase Agreement, the Indenture, the Officers’ Certificate and the Securities and to consummate the transactions contemplated thereby.

The Indenture has been duly authorized, executed and delivered by each of the Company and the Delaware Guarantor and, assuming the due authorization, execution and delivery thereof by the Trustee and each of the Guarantors (other than the Delaware Guarantor), constitutes a valid and binding agreement of each of the Company and the Delaware Guarantor, enforceable against each of the Company and the Delaware Guarantor in accordance with its terms.

3.	The Officers’ Certificate has been duly authorized, executed and delivered by the Company.

The Notes have been duly authorized and executed by the Company and, when authenticated by the Trustee and issued and delivered in the manner provided in the Indenture and the Purchase Agreement against payment of the consideration thereof, will constitute valid and binding obligations of the Company enforceable against the Company in accordance with their terms and will be entitled to the benefits provided by the Indenture.

5.	The Exchange Notes (have been duly authorized by the Company and the Exchange Guarantee by the Delaware Guarantor has been duly authorized by the Delaware Guarantor.

6.	The Guarantee by the Delaware Guarantor has been duly authorized by the Delaware Guarantor.

7.	The Purchase Agreement has been duly authorized, executed and delivered by the Company and the Delaware Guarantor.

The Registration Rights Agreement has been duly authorized, executed and delivered by each of the Company and the Delaware Guarantor and, assuming the due authorization, execution and delivery by you and each of the Guarantors (other than the Delaware Guarantor), constitutes a valid and binding agreement of each of the Company and the Delaware Guarantor, enforceable against each of the Company and the Delaware Guarantor in accordance with its terms.

No consent, approval, authorization or order of, or filing or registration with, any U.S. federal, Delaware, New York or Texas governmental authority or agency having jurisdiction over the Company or the Delaware Guarantor or, to our knowledge, any U.S. federal, Delaware, New York or Texas court, is required to be obtained or made that has not been obtained or made by the Company or the Delaware Guarantor for the execution and delivery by each of the Company or the Delaware Guarantor of the Transaction Documents to which it is a party, the execution and delivery of the Officers’ Certificate, the consummation by the Company or the Delaware Guarantor of the transactions contemplated by the Transaction Documents or the consummation of the Tender Offer, except (A) with respect to the Registration Rights Agreement and the transactions contemplated thereunder, the filing of one or more registration statements by the Company and the Guarantors with the Commission pursuant to the Securities Act of 1933, as amended (the “Securities Act”), an order by the Commission declaring each such registration statement effective and the qualification of the Indenture under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”); (B) as may be required under state securities or “blue sky” laws; (C) those which have been made or obtained, as applicable; and (D) filings with the Commission pursuant to Rule 13e-4 under the Exchange Act and current and periodic reporting obligations under the Exchange Act; provided that such counsel may state that they are not, in this paragraph 9, opining on whether registration of the Notes or the Guarantees under the Securities Act or qualification of the Indenture under the Trust Indenture Act is required for (i) the offer and sale of the Notes by the Company to you and (ii) the initial resale of the Notes by you (such opinion to be covered exclusively by paragraph 11 below).

10.

The authorization, execution and delivery by each of the Company and the Delaware Guarantor of the Transaction Documents to which it is a party, the performance by it of the obligations contemplated thereby, the authorization, execution and delivery of the Officers’ Certificate, and the consummation of the Tender Offer will not, (i) violate the Certificate of Incorporation or Bylaws, of the Company or the Delaware Guarantor; (ii) violate or result in a default under or breach of the Credit Agreement or any of the agreements listed on Schedule II hereto or (iii) violate any applicable provisions of existing U.S. federal law, the laws of the State of Texas, the laws of the State of New York or the General Corporation Law of the State of Delaware, except in the case of (ii) or (iii) where such violations, defaults and breaches would not, individually or in the aggregate, have a material adverse effect on the financial condition or results of operations of the Company and its subsidiaries and other consolidated entities, taken as a whole.

11.

Assuming the accuracy of the representations and warranties of the Company, the Guarantors and you in the Purchase Agreement and the due performance by the Company, the Guarantors and you of the agreements and undertakings contained therein, neither registration of the Notes or the Guarantees under the Securities Act nor qualification of the Indenture under the Trust Indenture Act is required for (i) the offer and sale of the Notes by the Company to you and (ii) the initial resale of the Notes by you, in each case in the manner contemplated by the Purchase Agreement, the Pricing Disclosure Package and the Final Offering Memorandum. We express no opinion, however, as to when or under what circumstances any Notes sold by you may be reoffered or resold.

12.

The Company is not and, after giving effect to the issuance of the Notes and the application of the proceeds from their sale as described in the Pricing Disclosure Package and the Final Offering Memorandum, will not be required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

13.

The statements set forth in the Pricing Disclosure Package and the Final Offering Memorandum under the captions “Description of the Notes” and “Description of Certain Indebtedness”, insofar as they purport to constitute summaries of the documents described therein, constitute accurate summaries of such documents in all material respects; and the statements made in the Pricing Disclosure Package and the Final Offering Memorandum under the caption “Certain United States Federal Income Tax Considerations,” insofar as they purport to constitute summaries of matters of U.S. federal tax law and regulations or legal conclusions with respect thereto, constitute accurate summaries of the matters described therein in all material respects, subject in each case to the assumptions and qualifications set forth therein.

We have reviewed the Pricing Disclosure Package and the Final Offering Memorandum and have participated in conferences with officers and other representatives of the Company and the Guarantors, with representatives of the Company’s independent registered public accounting firm and with your representatives and your counsel, at which the contents of the Pricing Disclosure Package, the Final Offering Memorandum and related matters were discussed. The purpose of our professional engagement was not to establish or confirm factual matters set forth in the Pricing Disclosure Package or the Final Offering Memorandum, and we have not undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Pricing Disclosure Package and the Final Offering Memorandum involve matters of a non-legal nature. Accordingly, we are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements included in the Pricing Disclosure Package and the Final Offering Memorandum (except to the extent stated in paragraph 12 above). Subject to the foregoing, and on the basis of the information we gained in the course of performing the services referred to above, we advise you that nothing came to our attention that caused us to believe that:

(1) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

(2) the Final Offering Memorandum, as of its date or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that in each case we have not been asked to, and do not, express any belief with respect to (a) the financial statements and other financial or accounting information contained or included or incorporated by reference therein or omitted therefrom, or (b) the representations and warranties included and other statements of fact contained in the exhibits to documents incorporated by reference therein.

Barclays Capital Inc.

As representative of the several initial purchasers named on Schedule I hereto

745 Seventh Avenue

New York, New York 10019

Ladies and Gentlemen:

I am the Vice President and General Counsel of Parker Drilling Company, a Delaware corporation (the “Company”), and in such capacity I have advised the Company in connection with the purchase today by the several initial purchasers named therein (the “Initial Purchasers”), for whom you are acting as representative, pursuant to the Purchase Agreement, dated as of April [—], 2012 (the “Purchase Agreement”), among the Company, the subsidiaries of the Company listed on Schedule II hereto (the “Guarantors”) and you, of $[—] aggregate principal amount of the Company’s 9 1/8% Senior Notes due 2018 (the “Notes”), guaranteed as to payment of principal, premium, if any, and interest by the Guarantors (the “Guarantees). The Notes are issued pursuant to an Indenture dated as of March 22, 2010 (the “Indenture”) among the Company, the Guarantors and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”), relating to the Notes and the Guarantees. Certain terms of the Notes were established pursuant to an Officers’ Certificate of the Company, dated as of April [—], 2012, pursuant to, and in accordance with, Section 2.01 of the Indenture (the “Officers’ Certificate”). I have been requested by the Company to furnish this opinion to you pursuant to Section 5(c) of the Purchase Agreement.

In connection with the opinion set forth below, I have examined copies of (i) the preliminary offering memorandum, dated April [—], 2012 (the “Preliminary Offering Memorandum”), (ii) the pricing supplement dated April [—], 2012 (the “Pricing Supplement” and together with the Preliminary Offering Memorandum, the “Pricing Disclosure Package”), (iii) the Final Offering Memorandum, dated April [—], 2012 (the “Final Offering Memorandum”), (iv) the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011 as filed under the Securities Exchange Act of 1934, as amended and incorporated by reference into the Pricing Disclosure Package and Final Offering Memorandum; (v) the Purchase Agreement; (vi) the Indenture;

(vii) the Officers’ Certificate; (viii) the Registration Rights Agreement, dated as of April [—], 2012 (the “Registration Rights Agreement”), among the Company, the Guarantors and you; (viii) the Credit Agreement dated May 15, 2008 by and among the Company as Borrower, Bank of America, N.A., as Administrative Agent, the lenders from time to time party thereto and the other persons from time to time party thereto as amended on April 1, 2011 (the “Credit Agreement”); (ix) the Certificate of Incorporation and Bylaws of the Company, each as amended to the date hereof; and (x) certain resolutions of the Board of Directors of the Company. I also have made such investigations of law and examined originals or copies of such other documents and records as I have deemed necessary and relevant as a basis for the opinion hereinafter expressed. With your approval, I have relied as to certain matters of fact on information obtained from public officials, officers of the Company and other sources believed by me to be reliable. In the course of the foregoing investigations and examinations, I assumed (i) the genuineness of all signatures on, and the authenticity of, all documents and records submitted to me as originals and the conformity to original documents and records of all documents and records submitted to me as copies; (ii) the truthfulness of all statements of fact set forth in the documents and records examined by me; (iii) the due authorization, execution and delivery by the parties thereto (other than the Company) of all documents and instruments examined by me; and (iv) that, to the extent such documents and instruments purport to constitute agreements of such parties, they constitute valid, binding and enforceable obligations of such parties.

Based on the foregoing and subject to the qualifications, limitations and assumptions set forth herein, and having due regard for such legal considerations as I deem relevant, I am of the opinion that:

The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or be in good standing would not, individually or in the aggregate, have a Material Adverse Effect (as defined in the Purchase Agreement).

Each significant subsidiary (as defined by Rule 1-02 of Regulation S-X) (each a “Significant Subsidiary”) of the Company (other than Parker Drilling Netherland B.V. and Parker Drilling Russia B.V.) is duly qualified as a foreign corporation or limited liability company, as the case may be, to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or be in good standing would not, individually or in the aggregate, have a Material Adverse Effect.

To my knowledge, after reasonable investigation, all of the issued shares of capital stock, ownership interests or partnership interests, as the case may be, of each Significant Subsidiary are owned directly or indirectly by the Company, free and clear of all liens, encumbrances, equities, claims or adverse interests (except as otherwise disclosed or contemplated in the Pricing Disclosure Package and the Final Offering Memorandum and for pledges in favor of the lenders under the Credit Agreement).

The issuance of the Notes and Exchange Notes in accordance with the Indenture and the sale of the Notes by the Company to you pursuant to the Purchase Agreement do not, and the authorization, execution and delivery of, and the performance by, the Company of its obligations, if any, under the Notes, Exchange Notes, the Indenture, the Officers’ Certificate, the Registration Rights Agreement and the Purchase Agreement will not, (i) result in the imposition or creation of (or the obligation to create or impose) a material lien, encumbrance, equity, claim or adverse interest under any agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries or their respective properties or assets is bound, other than such as would not reasonably be expected to have a Material Adverse Effect (as defined in the Purchase Agreement); or (ii) result in the suspension, termination or revocation of any Material Authorization (as defined in the Purchase Agreement) of the Company or any of its subsidiaries or any other impairment of the rights of the holder of any such Material Authorization.

To my knowledge, there are no contracts, agreements or understandings between the Company or any Guarantor, on the one hand, and any person, on the other hand, granting such person the right to require the Company or any Guarantor, as the case may be, to file a registration statement under the Securities Act with respect to any securities of the Company or any Guarantor owned or to be owned by such person and to require the Company or any Guarantor to include such securities in the securities registered pursuant to any registration statement filed in connection with the Exchange Securities (as defined in the Registration Rights Agreement) or in any securities being registered pursuant to any other registration statement filed by the Company or any Guarantor under the Securities Act.

The Company’s authorized capital stock is as set forth in the Pricing Disclosure Package and the Final Offering Memorandum.

To my knowledge, there are no contracts or other documents that would be required to be described in the Pricing Disclosure Package or the Final Offering Memorandum if the Pricing Disclosure Package or the Final Offering Memorandum were a prospectus included in a registration statement on Form S-3 that have not been so described therein.

To my knowledge, after reasonable investigation, except as set forth in the Pricing Disclosure Package and the Final Offering Memorandum, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property or assets of the Company or any of its subsidiaries is the subject that if determined adversely to the Company and its subsidiaries could, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect (as defined in the Purchase Agreement); and to my knowledge, no such proceedings are threatened by governmental authorities or others.

The foregoing opinion is based on and is limited to the General Corporation Law of the State of Delaware and the relevant Federal law of the United States of America. I express no opinion with respect to the state securities or blue sky laws of any jurisdiction or with respect to the law of any other jurisdiction. I am not admitted to the practice of law in the State of Delaware. I also express no opinion with respect to the anti-fraud provisions of the federal securities laws.

I am not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Pricing Disclosure Package or the Final Offering Memorandum and I have not independently verified the accuracy, completeness or fairness of such statements. I have, however, participated in conferences with other officers of the Company, its independent registered public accounting firm, your representatives and your counsel at which the contents of the Pricing Disclosure Package and the Final Offering Memorandum and related matters were discussed. Based upon such participation, I advise you that no facts have come to my attention that have caused me to believe that the (i) the Final Offering Memorandum (except for the financial statements, schedules and related data and other financial or accounting data, as to which I have not been asked to comment), as of its date or as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) the Pricing Disclosure Package (except for the financial statements, schedules and related data and other financial or accounting data, as to which I have not been asked to comment), as of [—] pm, New York City time, on April [—], 2012, contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

This opinion is solely for the Initial Purchasers’ benefit, in their capacity as the Initial Purchasers of the Notes, pursuant to Section 5(c) of the Purchase Agreement, and may not be used or relied upon by them in any other capacity or for any other purpose and may not be used or relied upon for any purpose by any other person or entity without my express prior written authorization. Except for the use permitted herein, this opinion may not be quoted, circulated or published, in whole or in part, or otherwise referred to, filed with or furnished to any other person or entity, without my express prior written authorization.

The opinion expressed herein is not an opinion with respect to matters of fact or a guarantee and should not be construed or relied upon as such. The opinion expressed herein is as of the date hereof, and I expressly disclaim any responsibility to update my opinion after the date hereof. This opinion is strictly limited to the matters stated herein, and no other or more extensive opinion is intended, implied or to be inferred beyond the matters expressly stated herein.

Very truly yours,

Jon-Al Duplantier

Re:

Parker Drilling Company

Ladies and Gentlemen:

We have acted as Oklahoma counsel to the subsidiaries of Parker Drilling Company, a Delaware corporation (the “Company”), listed on Annex 1 attached hereto (the “Oklahoma Guarantors”) in connection with the closing of the transactions contemplated by that certain Purchase Agreement, dated as of April [—], 2012 (the “Purchase Agreement”), among the Company, the subsidiaries of the Company (including the Oklahoma Guarantors) parties thereto as Guarantors, and Barclays Capital Inc., for itself and as representative of the Initial Purchasers (as therein defined). This opinion is delivered to you pursuant to Section 5(c) of the Purchase Agreement.

Capitalized terms used herein and not otherwise defined herein have the respective meanings assigned to them in the Purchase Agreement.

In connection with the opinions and statements expressed below, we have examined originals or copies, certified or otherwise identified to our satisfaction, of each of the following documents (collectively, the “Transaction Documents”):

the Purchase Agreement;

the Indenture, including the form of Note annexed thereto;

the Officers’ Certificate;

the Guarantees;

the Registration Rights Agreement;

the Pricing Disclosure Package; and

the Final Offering Memorandum.

We have also examined and relied upon originals or copies, certified or otherwise identified to our satisfaction, of (i) the articles or certificate of incorporation, articles of organization or certificate of limited partnership, as the case may be, and the bylaws, operating agreement or limited partnership agreement, as the case may be, of each of the Oklahoma Guarantors, each as amended and in effect on the date hereof (collectively, the “Organic

Documents”), (ii) a certificate of good standing for each of the Oklahoma Guarantors issued April [—], 2012, by the Oklahoma Secretary of State (collectively, the “Good Standing Certificates”), (iii) resolutions adopted by the Board of Directors or other governing body of each of the Oklahoma Guarantors (or of its manager or general partner), (iv) an officer’s certificate delivered on behalf of each of the Oklahoma Guarantors by its secretary or assistant secretary or by a secretary, assistant secretary or other responsible officer of its manager or general partner (collectively, the “Opinion Certificates”), and (v) an on-line search conducted by a legal assistant of this firm on April __, 2012, of the website maintained by the office of the Oklahoma Secretary of State with respect to the existence and good standing of each of the Oklahoma Guarantors. Due to the limited scope of our engagement and of this opinion, we have not examined any other documents or instruments, nor have we conducted any factual investigation of any matter. We have relied, without independent investigation, as to factual matters on the representations and warranties contained in the Transaction Documents and on the Good Standing Certificates and the Opinion Certificates. It is understood that you have consented to the scope of our examination.

We also made such examination of the laws of the State of Oklahoma and the federal law of the United States of America as we deemed relevant for the purpose of expressing our opinions.

We have assumed (a) the legal capacity of all natural persons executing the Transaction Documents and such other agreements, certificates and documents, (b) the genuineness of all signatures thereon, (c) the authority of all persons signing the Transaction Documents and such other agreements, certificates and documents on behalf of the parties thereto, other than officers and other representatives of the Oklahoma Guarantors, (d) the authenticity of all documents submitted to us as originals, and (e) the conformity to the original of all copies submitted to us as electronic copies, telecopies, photocopies or conformed copies.

Based upon the foregoing and subject to the additional qualifications, limitations and exceptions hereinafter set forth, we are of the opinion that:

1. Each of the Oklahoma Guarantors has been duly incorporated or formed, as the case may be, and is a validly existing corporation, limited liability company or limited partnership, as the case may be, in good standing under the laws of the State of Oklahoma.

2. Each of the Oklahoma Guarantors has the corporate, limited liability company or limited partnership power and authority, as the case may be, to own, lease and operate its respective properties and conduct its business as described in the Pricing Disclosure Package and Final Offering Memorandum.

3. The Indenture has been duly authorized, executed and delivered by each of the Oklahoma Guarantors.

4. The Guarantees of the Oklahoma Guarantors have been duly authorized by each of the applicable Oklahoma Guarantors.

5. The Purchase Agreement has been duly authorized, executed and delivered by each of the Oklahoma Guarantors.

6. No consent, approval, authorization or order of, or filing with, any Oklahoma governmental authority or agency having jurisdiction over the Oklahoma Guarantors or, to our knowledge, any Oklahoma court, is required to be obtained or made by the Oklahoma Guarantors for (i) the issuance of the Notes and the Exchange Securities (as defined in the Registration Rights Agreement) in accordance with the Indenture, (ii) the sale of the Notes by the Company to you pursuant to the Purchase Agreement, or (iii) the execution, delivery and performance by the Company and the Oklahoma Guarantors of their respective obligations under the Notes, the Exchange Securities, the Registration Rights Agreement, the Indenture (including the Guarantees), the Officers’ Certificate, or the Purchase Agreement, except as may be required under the Oklahoma Securities Act and regulations promulgated thereunder in connection with the purchase and distribution by you of the Notes and the Exchange Notes.

7. The issuance of the Notes and the Exchange Notes in accordance with the Indenture, the issuance of the Guarantees by the Oklahoma Guarantors and the sale of the Notes by the Company to you pursuant to the Purchase Agreement do not, and the authorization, execution and delivery of, and the performance by, the Company and each of the Oklahoma Guarantors of their obligations under the Notes, the Exchange Notes, the Registration Rights Agreement, the Indenture, the Officers’ Certificate and the Purchase Agreement will not, (i) violate the Organic Documents of any of the Oklahoma Guarantors, or (ii) violate any applicable provisions of the Oklahoma General Corporation Act, the Oklahoma Limited Liability Company Act or the Oklahoma Revised Uniform Limited Partnership Act, as the case may be.

The foregoing opinions are subject to the following additional qualifications, limitations and exceptions:

A. We express no opinion herein concerning the laws of any jurisdiction other than the laws of the State of Oklahoma and the relevant federal law of the United States of America. We express no opinions regarding the ordinances, rules or regulations of any county, municipality or special political subdivision of the State of Oklahoma.

B. Our opinions in Paragraph 6 above insofar as they relate to laws, statutes, rules or regulations of the State of Oklahoma are based upon those laws, statutes, rules or regulations which, in our experience, are normally applicable to transactions of the type contemplated by the Transaction Documents or entities engaged in the type of business engaged in by the Oklahoma Guarantors as described in the Transaction Documents.

C. This opinion is rendered as of the date hereof and based solely upon compilations of the applicable laws as were available to the public on the date hereof. We assume no obligation to update or supplement this opinion to reflect any facts or circumstances that may hereafter come to our attention or any changes in law that may hereafter occur.

D. This opinion is limited to the matters expressly set forth herein, and no opinion is to be inferred or may be implied beyond the matters expressly stated herein.

E. The opinions expressed herein have been rendered at your request, are solely for the benefit of you, the Initial Purchasers and any Subsequent Purchasers who acquire Securities in accordance with the express provisions of the Purchase Agreement, may not be relied upon by you or any other Purchaser for any purpose, and may not be communicated or published by you

to any other Person for any purpose or filed with any governmental authority without our prior written approval in each instance. At your request, we hereby consent to reliance hereon by any Purchaser of the Securities made in accordance with the express provisions of the Purchase Agreement, on the condition and understanding that (i) this letter speaks only as of the date hereof, and (ii) any such reliance by a future Purchaser must be actual and reasonable under the circumstances existing at the relevant time, including any changes in law, facts or any other developments known to or reasonably knowable by the Purchaser at such time.

Ladies and Gentlemen:

We have acted as special Nevada counsel to Parker Drilling Company, a Delaware corporation (the “Company”), and in such capacity have advised the Company and the subsidiaries of the Company listed above (the “Nevada Guarantors”) in connection with the purchase today by you pursuant to the Purchase Agreement, dated as of April [—], 2012 (the “Purchase Agreement”), among the Company, the Nevada Guarantors, the subsidiaries of the Company listed on Schedule II hereto (together with the Nevada Guarantors, the “Guarantors”) and you, as representative of the several initial purchasers named therein (the “Initial Purchasers”), of $[—] aggregate principal amount of the Company’s 9 1/8% Senior Notes due 2018 (the “Notes”), guaranteed as to payment of principal, premium, if any, and interest by the Guarantors (the “Guarantees”). The Notes are issued pursuant to an Indenture dated as of March 22, 2010 (the “Indenture”) among the Company, the Guarantors and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”), relating to the Notes and the Guarantees, and certain terms of the Notes were established pursuant to an Officers’ Certificate of the Company, dated as of April [—], 2012, pursuant to, and in accordance with, Section 2.01 of the Indenture (the “Officers’ Certificate”). We have been requested by the Company to furnish this opinion to you pursuant to Section 5(c) of the Purchase Agreement.

In connection with the opinion set forth below, we have examined copies of (i) the preliminary offering memorandum, dated April [—], 2012 (the “Preliminary Offering Memorandum”), (ii) the pricing supplement dated April [—], 2012 (the “Pricing Supplement” and together with the Pre-liminary

Offering Memorandum, the “Pricing Disclosure Package”), (iii) the Final Offering Memorandum, dated April [—], 2012 (the “Final Offering Memorandum”), (iv) the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011 (other than information that is furnished rather than filed in accordance with Securities and Exchange Commission rules) as filed under the Securities Exchange Act of 1934, as amended and incorporated by reference into the Pricing Disclosure Package and Final Offering Memorandum; (v) the Purchase Agreement; (vi) the Indenture; (vii) the Officers’ Certificate; (viii) the Registration Rights Agreement, dated as of April [—], 2012 (the “Registration Rights Agreement”), among the Company, the Guarantors and you; (ix) the charter, bylaws or other constitutive documents of each of the Nevada Guarantors, each as amended to the date hereof; and (x) certain resolutions of the Board of Directors of each of the Nevada Guarantors. We also have made such investigations of law and examined originals or copies of such other documents and records as we have deemed necessary and relevant as a basis for the opinion hereinafter expressed. With your approval, we have relied as to certain matters of fact exclusively on information obtained from public officials, officers of the Company, and officers of the Nevada Guarantors. We have performed no other investigation, inquiry, or due diligence, and no inference as to our knowledge of the existence or absence of such facts may be drawn from our representation in this matter. In the course of the foregoing investigations and examinations, we assumed (i) the genuineness of all signatures on, and the authenticity of, all documents and records submitted to us as originals and the conformity to original documents and records of all documents and records submitted to us as copies; (ii) the truthfulness of all statements of fact set forth in the documents and records examined by us; (iii) the due authorization, execution and delivery by the parties thereto (other than the Nevada Guarantors) of all documents and instruments examined by us; and (iv) that, to the extent such documents and instruments purport to constitute agreements of such parties, they constitute valid, binding and enforceable obligations of such parties.

Based on the foregoing and subject to the qualifications, limitations and assumptions set forth herein, and having due regard for such legal considerations as we deem relevant, we are of the opinion that:

Each of the Nevada Guarantors has been duly incorporated and is a validly existing corporation in good standing under the laws of the State of Nevada; and each of the Nevada Guarantors has the corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Pricing Disclosure Package and the Final Offering Memorandum.

The Indenture has been duly authorized, executed and delivered by each of the Nevada Guarantors.

The Guarantees and the guarantees of the Exchange Securities (as defined in the Registration Rights Agreement) have been duly authorized by each of the Nevada Guarantors.

The Purchase Agreement has been duly authorized, executed and delivered by each of the Nevada Guarantors.

The Registration Rights Agreement has been duly authorized, executed and delivered by each of the Nevada Guarantors.

No consent, approval, authorization or order of, or filing with, any Nevada governmental authority or agency having jurisdiction over the Nevada Guarantors or, to my knowledge after due inquiry, any Nevada court, is required to be obtained or made and has not been obtained or made by the Nevada Guarantors for the issuance of the Guarantees in accordance with the Indenture or the execution, delivery and performance by the Nevada Guarantors of their obligations under the Notes, the Exchange Securities (as defined in the Registration Rights Agreement), the Indenture (including the Guarantees), the Officers’ Certificate, the Registration Rights Agreement or the Purchase Agreement, except as may be required under state securities or “blue sky” laws in connection with the purchase and distribution of the Notes by you.

The issuance of the Guarantees by the Nevada Guarantors does not, and the authorization, execution and delivery of, and the performance by, each of the Nevada Guarantors of their obligations under the Notes, the Exchange Securities, the Indenture, the Officers’ Certificate, the Registration Rights Agreement and the Purchase Agreement will not, (i) violate the Articles of Incorporation or Bylaws, each as amended to the date hereof, of any of the Nevada Guarantors; or (ii) violate any applicable provisions of the General Corporation Law or limited liability law of the State of Nevada.

The foregoing opinion is, with your approval, based on and is limited to the General Corporation Law of the State of Nevada and the relevant Federal law of the United States of America. We express no opinion with respect to the state securities or blue sky laws of any jurisdiction or with respect to the law of any other jurisdiction. We also express no opinion with respect to the anti-fraud provisions of the federal securities laws.

This opinion is solely for the Initial Purchasers’ benefit, as the Initial Purchasers of the Notes, pursuant to Section 5(c) of the Purchase Agreement, and may not be used or relied upon by the Initial Purchasers in any other capacity or for any other purpose and may not be used or relied upon for any purpose by any other person or entity without my express prior written authorization. Except for the use permitted herein, this opinion may not be quoted, circulated or published, in whole or in part, or otherwise referred to, filed with or furnished to any other person or entity, without my express prior written authorization.
