Texas Entities, or any other guarantor of the Exchange Notes in regard to (i) the formation of Parent or any of the Texas Entities, or (ii) except for the preparation of this opinion letter and the review of the Indenture and Texas Constituent Documents in connection therewith, the offering, issuance, or sale of the Exchange Notes, or the negotiation of the Guarantees or any other guarantee, including, without limitation, the development or preparation of any offering memorandum or circular, the Registration Statement (other than the section titled “Texas Registrants” in Item 20 of Part II thereof), any other registration statement, or other disclosure document, or any agreement, instrument, or document related to any of the foregoing, and (b) have not advised any of the Texas Entities with respect to the consummation of the transactions contemplated by any of the foregoing, or the internal governance considerations related to any of the foregoing, and our sole representation of the Texas Entities is limited to rendering the opinions expressed herein. We have not reviewed any documents (other than the Indenture and the Texas Constituent Documents) that are referred to in or incorporated by reference into the Indenture or any Texas Constituent Document. In addition, we have assumed that there exists no provision in any document that we have not reviewed that is inconsistent with the opinions set forth herein.
In rendering the opinions expressed herein, we have (a) examined the Indenture (including the Guarantee), Texas Constituent Documents, certificates of representatives of the Texas Entities, certificates and other communications of public officials, and such other instruments, agreements, and documents as are in our judgment necessary to enable us to render the opinions expressed herein, and (b) as to questions of fact material to the opinions expressed herein, and as to factual matters arising in connection with our examination of the aforesaid materials, relied, to the extent we deemed appropriate, upon the factual representations and warranties contained in the Indenture, the Texas Constituent Documents, and such certificates, communications, instruments, agreements, and documents and certain facts stated elsewhere herein, and we have made no independent investigation into the accuracy of such information, representations, warranties, and certificates.
In making such examination and in such reliance, we have assumed (i) the authenticity and completeness of all records, certificates, instruments, agreements, and other documents submitted to us as originals, (ii) the conformity to authentic originals, records, certificates, instruments, agreements, and other documents of all documents submitted to us as copies, (iii) the legal capacity of each natural person identified in, or indicated as having executed, any of those records, certificates, instruments, agreements, and other documents, (iv) the genuineness of all signatures on all such records, certificates, instruments, agreements, and other documents, (v) the due execution and delivery by all parties thereto (except to the extent set forth in paragraph 5 below) of the Indenture, and (vi) the enforceability of the Indenture against all parties thereto.
In rendering the opinions expressed herein, we also have assumed that (i) Precision Drilling Holdings Company, a Nevada corporation and general partner of the Texas Partnership Entity (“PDHC”) (1) has been duly organized or formed, (2) is validly existing as a corporation in good standing under the laws of the State of Nevada, and (3) has the corporate power and

authority to execute and deliver, in its capacity as general partner of the Texas Partnership Entity, the Indenture, and (ii) the execution and delivery by PDHC, in its capacity as general partner of the Texas Partnership Entity, of the Indenture have been duly authorized by all necessary corporate action on the part of PDHC in accordance with the laws of the State of Nevada.
Based upon the foregoing and in the reliance thereon, and subject to and qualified by the assumptions, qualifications, limitations, and exceptions set forth herein, and having due regard for such legal considerations as we deem relevant, we are of the opinion that:
1. Each Texas Corporate Entity (a) is validly existing as a corporation in good standing under the laws of the State of Texas, and (b) has the corporate power and authority to execute and deliver, and to perform its obligations (including its Guarantee obligations) under, the Indenture.
2. The Texas Partnership Entity (a) is validly existing as a limited partnership in good standing under the laws of the State of Texas, and (b) has the limited partnership power and authority to execute and deliver, and to perform its obligations (including its Guarantee obligations) under, the Indenture.
3. The execution and delivery by each Texas Corporate Entity of the Indenture, and the performance by each Texas Corporate Entity of its obligations (including its Guarantee obligations) thereunder, have been duly authorized by all necessary corporate action.
4. The execution and delivery by the Texas Partnership Entity of the Indenture, and the performance by the Texas Partnership Entity of its obligations (including its Guarantee obligations) thereunder, have been duly authorized by all necessary limited partnership action.
5. The Indenture has been duly executed and delivered by each Texas Entity.
6. Neither the execution and delivery by a Texas Entity of the Indenture, nor the performance by such Texas Entity of its obligations (including its Guarantee obligations) thereunder, will violate, or result in a breach of, or constitute a default under (a) the articles of incorporation, certificate of incorporation, or certificate of formation, and bylaws or limited partnership agreement, as the case may be, of such Texas Entity, or (b) any statutory law or regulation of the State of Texas applicable to such Texas Entity.
The foregoing opinions expressed herein are further subject to, and qualified by, the following assumptions, exceptions, qualifications and limitations:
A. The opinions expressed herein are limited exclusively to the internal laws of the State of Texas.

We hereby consent to the filing of this opinion letter as an exhibit to the Registration Statement. The opinions expressed herein are as of the date hereof (and not as of any other date, including, without limitation, the effective date of the Indenture, if a date other than the date hereof) or, to the extent a reference to a certificate or other document dated another date is made herein, to such date, and we make no undertaking to amend or supplement such opinions as facts and circumstances come to our attention or changes in the law occur which could affect such opinions.
