Ladies and Gentlemen:

Resolute Energy Corporation, a Delaware corporation (the “Company”), proposes to issue and sell to the initial purchasers listed in Schedule 1 hereto (the “Initial Purchasers”), for whom you are acting as representative (the “Representative”), an aggregate of 55,000 shares of 8-1/8% Series B Cumulative Perpetual Convertible Preferred Stock of the Company, with an initial liquidation preference of $1,000.00 per share (the “Convertible Preferred Stock”) (such Convertible Preferred Stock, the “Firm Securities”) and, at the option of the Initial Purchasers, up to an additional 7,500 shares of Convertible Preferred Stock (such Convertible Preferred Stock, the “Option Securities”). The Firm Securities and the Option Securities are herein referred to as the “Securities.” The Securities will be convertible, subject to certain conditions set forth in the certificate of designations establishing the Securities (the “Certificate of Designations”), for shares of common stock of the Company, par value $0.0001 per share (the “Common Stock”), in accordance with the terms of the Securities. “Underlying Shares,” as used herein, means the maximum number of shares of Common Stock issuable upon conversion of the Securities (including the maximum number of shares of Common Stock that may be issued upon conversion of the Securities in connection with a Fundamental Change (as described in the Disclosure Package (as defined below)). The Underlying Shares may have attached thereto rights (the “Rights”) to purchase fractions of a share of Series A Junior Participating Preferred Stock of the Company upon the occurrence of certain events, as more particularly set forth in the Rights Agreement (the “Rights Agreement”) dated as of May 17, 2016 between the Company and Continental Stock Transfer & Trust Company, as rights agent.

To the extent there are no additional Initial Purchasers listed on Schedule 1 other than you, the term Representative as used herein shall mean you, as Initial Purchasers, and the terms Representative and Initial Purchasers shall mean either the singular or plural as the context requires.

The sale of the Securities to the Initial Purchasers will be made without registration of the Securities under the Securities Act of 1933, as amended (the “Securities Act”) in reliance upon exemptions from the registration requirements of the Securities Act. The Company understands that the Initial Purchasers propose to offer the Securities in accordance with Rule 144A under the Securities Act to “qualified institutional buyers” (as defined in Rule 144A) as soon as the Representative deems advisable after this Purchase Agreement (this “Agreement”) has been executed and delivered.

It is expected that concurrent with the Company and the Initial Purchasers entering into this Agreement , the Company will enter into a purchase and sale agreement with Firewheel Energy, LLC (the “Seller”), relating to a proposed acquisition of assets (the “Acquisition”) from the Seller. The closing of the offering of the Securities is not conditioned on the completion of the Acquisition.

In the event that the Acquisition is completed, it is expected that the Acquisition would be financed with the net proceeds of the offering of the Securities, together with borrowings under the Company’s Second Amended and Restated Credit Agreement, dated March 30, 2010, among the Company, as borrower, ▇▇▇▇▇ Fargo Bank National Association, as administrative agent, and the other agents and lenders party thereto (as amended, restated, supplemented and otherwise modified from time to time, the “Revolving Credit Facility”), and the issuance of shares of our Common Stock in a private placement to the Seller (the “Equity Consideration”).

In connection with the offering of Securities, the Company has obtained an amendment (the “RBL Amendment”) to the Company’s revolving credit agreement (the “Revolving Credit Agreement”).

In connection with the offering of the Securities, the Company has prepared a preliminary offering memorandum, dated September 30, 2016 (including the annexes thereto and the information incorporated by reference therein, the “Preliminary Memorandum”), and a final offering memorandum, dated October 4, 2016 (as amended or supplemented to the date of such amendment or supplement, including the annexes thereto and the information incorporated by reference therein, the “Final Memorandum”). Each of the Preliminary Memorandum and the Final Memorandum sets forth certain information concerning the Company and the Securities. The Company hereby confirms that it has authorized the use of the Disclosure Package (as defined below) and the Final Memorandum and any amendment or supplement thereto, in connection with the offer and sale of the Securities by the Initial Purchasers. Unless stated to the contrary, any references herein to the terms “amend,” “amendment” or “supplement” with respect to the Disclosure Package and the Final Memorandum shall be deemed to refer to and include any information filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), subsequent to the Time of Sale that is incorporated by reference therein.

(s) Listing of Underlying Shares. The Underlying Shares shall have been approved for listing on the NYSE and evidence thereof shall have been provided to the Initial Purchasers.

(t)DTC Eligibility. The Securities shall be eligible for clearance and settlement through The Depository Trust Company.

(u) Additional Documents. On or prior to the Closing Date or any Additional Closing Date, as the case may be, the Company shall have furnished to the Representative such further certificates and documents as the Representative may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representative and counsel for the Initial Purchasers, this Agreement and all obligations of the Initial Purchasers hereunder may be cancelled at, or at any time prior to, the Closing Date by the Representative. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

7.Indemnification and Contribution.

(a) Indemnification of the Initial Purchasers. The Company agrees to indemnify and hold harmless each Initial Purchaser, and each of their respective directors, partners, officers, employees, affiliates and agents of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities or actions in respect thereof arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Disclosure Package, the Final Memorandum, any Issuer Written Communication or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities, or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of

or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Memorandum, the Disclosure Package or the Final Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Company, by or on behalf of any Initial Purchaser through the Representative specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Company may otherwise have.

(b) Indemnification of the Company. Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Company, its directors, officers, and each person, if any, who controls the Company within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity to each Initial Purchaser, but only with reference to written information relating to such Initial Purchaser furnished to the Company by or on behalf of such Initial Purchaser through the Representative specifically for inclusion in the Preliminary Memorandum, the Disclosure Package, the Final Memorandum or any Issuer Written Communication (or in any amendment or supplement thereto). This indemnity agreement will be in addition to any liability that any Initial Purchaser may otherwise have. The Company acknowledges that the fourth paragraph and the fourth and fifth sentences of the seventh paragraph and the section entitled “Stabilization and Short Positions,” in each case, in the section entitled “Plan of Distribution” in the Preliminary Memoranda and the Final Memorandum constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Memoranda and the Final Memorandum or in any amendment or supplement thereto.

(c) Notice and Procedures. Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) of this Section 7 unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) of this Section 7. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the

indemnifying party; (iii) 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 the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) Contribution. In the event that the indemnity provided in paragraph (a) or (b) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company, on the one hand, and the Initial Purchasers, on the other, severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively “Losses”) to which the Company and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and by the Initial Purchasers on the other from the offering of the Securities; provided, however, that in no case shall any Initial Purchaser be responsible under this Section 7 for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Initial Purchaser hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company, on the one hand, and the Initial Purchasers, on the other, severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, on the one hand, and the Initial Purchasers, on the other, in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company, on the one hand, or the Initial Purchasers, on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person who controls an Initial Purchaser within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee, affiliate and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representative, by notice given to the Company prior to delivery of and payment for the Securities on the Closing Date or, in the case of the Option Securities, any Additional Closing Date, if at any time prior to such time (i) trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such exchange; (ii) a banking moratorium shall have been declared either by U.S. federal or New York State authorities; or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representative, impractical or inadvisable to proceed with the offering or delivery of the Securities on the Closing Date or any Additional Closing Date, as the case may be, as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

10. Defaulting Initial Purchaser.

(a) If, on the Closing Date or any Additional Closing Date, as the case may be, any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder on such date, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date or any Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Disclosure Package, in the Final Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Disclosure Package or the Final Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers as provided in paragraph (a) of this Section 10, the aggregate number of shares of Securities that remain unpurchased on the Closing Date or any Additional Closing Date, as the case may be, does not exceed ten percent of the aggregate number of shares of Securities to be purchased on such date, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the number of shares of Securities that such Initial Purchaser agreed to purchase hereunder (or under any other agreement pursuant to which such Initial Purchaser agreed to purchase shares of Securities that a defaulting

Initial Purchaser failed to purchase) on such date plus such Initial Purchaser’s pro rata share (based on the number of shares of Securities that such Initial Purchaser agreed to purchase on such date) of the shares of Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers as provided in paragraph (a) of this Section 10, the aggregate number of shares of Securities that remain unpurchased on the Closing Date or any Additional Closing Date, as the case may be, exceeds ten percent of the aggregate amount of shares of Securities to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) of this Section 10, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Initial Purchasers to purchase shares of Securities on such Additional Closing Date, as the case may be, shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company or any non-defaulting Initial Purchaser for damages caused by its default hereunder, including expenses paid pursuant to Section 11(b) below.

11. Payment of Expenses.

(a) The Company agrees, whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, to pay all expenses, costs, fees and taxes incident to and in connection with (i) the authorization, issuance, sale and delivery of the Securities to be sold by the Company and any stamp duties, transfer or other taxes payable in that connection; (ii) the preparation and printing of the Preliminary Memoranda, the Final Memorandum, any Issuer Written Communication, and any amendment or supplement thereto; (iii) the distribution of the Preliminary Memoranda, the Final Memorandum, any Issuer Written Communication, and any amendment or supplement thereto, or any document incorporated by reference therein, all as provided in this Agreement; (iv) the production and distribution of this Agreement, any supplemental agreement among Initial Purchasers, and any other related documents in connection with the offering, purchase, sale and delivery of the Securities; (v) the listing of the Underlying Shares on the NYSE; (vi) the qualification of the Securities under state securities laws and the preparation, printing and distribution of a Blue Sky Memorandum (including related reasonable fees and expenses of counsel to the Initial Purchasers); (vii) the investor presentations, any pre-marketing activities or any “road show” undertaken in connection with the marketing of the Securities, including, without limitation, reasonable expenses associated with any electronic road show, travel and lodging expenses of the representatives and officers of the Company and the Initial Purchasers and the cost of any aircraft chartered in connection with the road show; (viii) the fees and expenses of the Company’s accountants and the fees and expenses of counsel for the Company; (ix) the fees and expenses of the Company’s transfer agent; and (x) all other costs and expenses incident to the performance of the obligations of the Company pursuant to this Agreement. Except as provided in this Section 11, the Initial Purchasers shall pay their own costs and expenses, including the fees and expenses of their

counsel, any transfer taxes on resale of the Securities by them and the expenses of advertising any offering of the Securities made by the Initial Purchasers. (b) If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 9 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Initial Purchasers, the Company will reimburse the Initial Purchasers severally through the Representative on demand for all expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

12.Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the indemnified persons referred to in Section 7 hereof and their respective successors, and, except as expressly set forth in Section 5(k) hereof, no other person will have any right or obligation hereunder.

13. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the 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 the Initial Purchasers or the Company or any of the indemnified persons referred to in Section 7 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 11 hereof shall survive the termination or cancellation of this Agreement.

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (d) the term “significant subsidiary” has the meaning set forth in Rule 1-02 of Regulation S-X under the Exchange Act.

15. No Fiduciary Duty. The Company hereby acknowledges that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Initial Purchasers and any affiliate through which it may be acting, on the other, (b) the Initial Purchasers are acting as principal and not as an agent or fiduciary of the Company and (c) the Company’s engagement of the Initial Purchasers in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Initial Purchasers has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Initial Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

Annex A

Form of Opinion and 10b-5 of Counsel for the Company

October 7, 2016

BMO Capital Markets Corp.

▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇^▇▇ ▇▇▇▇▇
▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

We have acted as counsel to Resolute Energy Corporation, a Delaware corporation (the “Company”), in connection with that certain Purchase Agreement, dated as of October 4, 2016 (the “Agreement”), between the Company and BMO Capital Markets Corp. (the “Initial Purchaser”), providing for the sale by the Company and the purchase by the Initial Purchaser of 55,000 shares of 8-1/8% Series B Cumulative Perpetual Convertible Preferred Stock of the Company (the “Firm Securities”) and, at the option of the Initial Purchaser, the sale by the Company and the purchase by the Initial Purchaser of up to 7,500 additional shares of 8-1/8% Series B Cumulative Perpetual Convertible Preferred Stock of the Company (together with the Firm Securities, the “Securities”). The Securities will be convertible into shares of common stock, par value $0.0001 per share, of the Company (the “Common Stock”) pursuant to the Certificate of Designations of 8-1/8% Series B Cumulative Perpetual Convertible Preferred Stock (the “Certificate of Designations” and, together with the Agreement, collectively, the “Transaction Documents”) establishing the terms of the Securities filed with the Secretary of State of the State of Delaware. This opinion is being issued to you pursuant to Section 6(h) of the Agreement. Capitalized terms used but not defined herein shall have the meanings given to them in the Agreement.

In connection with the opinion set forth below, we have examined (i) an executed counterpart of the Agreement, (ii) the Amended and Restated Certificate of Incorporation of the Company, as amended to the date hereof (the “Certificate of Incorporation”), including the Certificate of Designations, (iii) the Amended and Restated By-Laws of the Company, as amended to the date hereof (together with the Certificate of Incorporation, as amended by the Certificate of Designations, the “Organizational Documents”), (iv) certain resolutions of the Board of Directors of the Company relating to the issuance of the Securities and the other transactions contemplated by the Agreement, (v) the final Offering Memorandum, dated as of October 4, 2016, relating to the sale of the Securities by the Initial Purchaser (the “Offering Memorandum”), (vi) the Disclosure Package, (vii) the Rights Agreement, dated as of May 17, 2016, between the Company and Continental Stock Transfer & Trust Company, as rights agent, and (viii) those documents incorporated by reference into the Offering Memorandum and the Disclosure Package.

We have also examined such other corporate documents and records of the Company, certificates of public officials and representatives of the Company, and other statutes, instruments, documents and laws as we have deemed necessary for purposes of this opinion. We have relied as to factual matters, without independent inquiry, on the representations set forth in the Agreement, certificates of officers of the Company delivered pursuant to the Agreement, one or more certificates of officers of the Company delivered to us in connection with this opinion (each, an “Officer’s Certificate”), and such other documents, records, certificates and instruments as we deemed necessary for purposes of this opinion. In such examination, we have assumed, with your consent, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity with originals of all documents submitted to us as copies and the authenticity of the originals of such documents, the due execution and delivery of the Agreement by the parties thereto (other than the Company), that all parties (other than the Company) are duly organized, validly existing and in good standing under the jurisdictions of their organization, that the Agreement has been duly authorized by the parties thereto (other than the Company), and constitutes the valid and binding obligations of the parties thereto (other than the Company), enforceable against them in accordance with its terms, and that the proceeds from the issuance and sale of the Securities will be applied as set forth in the Disclosure Package and the Offering Memorandum.

The opinions set forth in paragraph 5 below regarding the qualification and good standing of the Company (i) are based solely on our review of certificates of good standing of the Company (including, where applicable, certificates of incorporation of the Company itemized in such certificates), (ii) speak only as of October [__], 2016, the date indicated on such certificates of good standing, and (iii) are limited to the meaning set forth in such certificates by the applicable issuing authority and applicable law. We express no opinion herein, including in paragraph 7 below, regarding the Company’s, any of its subsidiaries’ or any other person’s compliance with financial covenants. The opinion in paragraph 2 regarding investment company status is based as to matters of fact solely on the representations set forth in an Officer’s Certificate and a review of financial information for the Company as set forth in its annual report on Form 10-K for the year ended December 31, 2015 and its quarterly report for the six months ended June 30, 2016, in each case, as filed with the U.S. Securities and Exchange Commission pursuant to the Securities Exchange Act of 1934, as amended. For purposes of determining whether a particular entity is an “investment company” as defined in the Investment Company Act of 1940, as amended (the “Investment Company Act”), it is necessary to examine the “value” of the assets of such entity within the meaning of Section 2(a)(41)(A) of the Investment Company Act. Section 2(a)(41)(A)(ii) of the Investment Company Act provides that the “value” of certain assets held by an entity shall be the “fair value” of such assets as of the end of the previous fiscal quarter as determined in good faith by such entity’s board of directors (or similar governing body). Although the aforementioned Officer’s Certificate may make certain certifications regarding the value of the assets of the Company and/or its subsidiaries, the officer executing the Officer’s Certificate did not request the board of directors (or the equivalent governing body) of the Company or of any of its subsidiaries to determine the value of any assets required to be valued at “fair value” pursuant to Section 2(a)(41)(A)(ii), but obtained values from other sources deemed to be reliable. We have assumed, however, with your permission, that all assets of the Company and its subsidiaries that are required to be valued at “fair value” pursuant to Section 2(a)(41)(A)(ii) of the Investment Company Act by the board of directors (or the equivalent governing body) of the Company, or of the relevant subsidiary, as the case may be,

would have been valued at the same values ascribed to such assets for purposes of the Officer’s Certificate had the board of directors (or the equivalent governing body) of the Company or of the relevant subsidiary determined the “fair value” thereof pursuant to that section.

Based on and subject to the foregoing and the comments and qualifications set forth below, it is our opinion that:

1.Assuming the accuracy of the representations and warranties and compliance with the agreements in the Agreement and deemed to have been made or agreed to in the “Transfer Restrictions” section of the Disclosure Package and the Offering Memorandum, no registration under the Securities Act of 1933, as amended, of the Securities is required for the sale and delivery of the Securities by the Company to the Initial Purchaser in the manner contemplated in the Agreement or for the offer and sale by the Initial Purchaser of the Securities in the manner contemplated in the Agreement, in the Disclosure Package and in the Offering Memorandum.

2.The Company is not, and after giving effect to the sale and delivery of the Securities and the application of the proceeds thereof as described in the Disclosure Package and the Offering Memorandum, will not be, an “investment company” as defined in the Investment Company Act.

3.The statements in the Disclosure Package and Offering Memorandum under the heading “Material U.S. Federal Income Tax Considerations,” insofar as they purport to constitute summaries of (i) matters of United States federal tax law and regulations or legal conclusions with respect thereto or (ii) the terms of statutes, rules or regulations, constitute accurate summaries of such matters in all material respects.

4.The statements in the Disclosure Package and Offering Memorandum under the heading “Description of Series B Cumulative Perpetual Convertible Preferred Stock” and “Description of Capital Stock” and the information contained in the form of pricing term sheet attached as Annex C to the Agreement, in each case insofar as they purport to constitute summaries of the terms of the Securities and the Common Stock, constitute accurate summaries of the terms of the Securities and Common Stock in all material respects.

5.The Company has been duly incorporated and is validly existing and in good standing under the laws of the State of Delaware, with full corporate power and authority to own or lease, as the case may be, and to operate its properties and conduct its business as described in the Disclosure Package and the Offering Memorandum.

6.The Securities have been duly authorized by the Company and, when issued, paid for and delivered pursuant to the terms of the Agreement, will be validly issued, fully paid, non-assessable and free and clear of any preemptive or similar rights under the Organizational Documents. The Common Stock issuable upon conversion of the Securities pursuant to the Certificate of Designations (the “Conversion Shares”) has been duly authorized and reserved for issuance and, when issued and delivered in accordance with the Organizational Documents, will be validly issued, fully paid and non-assessable, and the issuance of such Conversion Shares will not give rise to any preemptive or similar rights under the Organizational Documents.

7.None of the Company’s execution and delivery of the Agreement, the filing of the Certificate of Designations, the performance by the Company of its obligations under the Transactions Documents, the issuance and sale of the Securities to the Initial Purchaser or the issuance of the Conversion Shares upon conversion of the Securities in accordance with the Certificate of Designations will conflict with, result in a breach or violation of, or result in the imposition of any lien, charge or encumbrance upon any property or asset of the Company or its subsidiaries pursuant to (i) the Organizational Documents; (ii) the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, covenant or instrument set forth on Schedule A to this opinion; or (iii) any Applicable Law (as defined below), except in the case of (ii) and (iii) above, for any such breach or violation that would not reasonably be expected to have a material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its subsidiaries, taken as a whole, and assuming in the case of clause (iii) above, that all filings or other public disclosures regarding the transactions contemplated by the Agreement required under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder, and applicable New York Stock Exchange rules, have in all cases been made or obtained, as applicable.

(a)the Disclosure Package, as amended or supplemented at the date and time that the Agreement was executed and delivered by the parties thereto, 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

RESOLUTE ENERGY CORPORATION

55,000 Shares of 8⅛% Series B Cumulative Perpetual Convertible Preferred Stock

This pricing term sheet is qualified in its entirety by reference to the Preliminary Offering Memorandum (as supplemented by Supplement No. 1 dated October 4, 2016, the “Preliminary Offering Memorandum”). The information in this pricing term sheet supplements the Preliminary Offering Memorandum and updates and supersedes the information in the Preliminary Offering Memorandum to the extent it is inconsistent with the information in the Preliminary Offering Memorandum. Capitalized terms used in this pricing term sheet but not defined have the meanings given them in the Preliminary Offering Memorandum.

The convertible preferred stock and the common stock issuable upon conversion of the convertible preferred stock, if any, have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any other jurisdiction. The convertible preferred stock and the common stock issuable upon conversion of the convertible preferred stock, if any, may not be offered or sold except in transactions exempt from, or not subject to, the registration requirements of the Securities Act. Accordingly, the convertible preferred stock and the common stock issuable upon conversion of the convertible preferred stock, if any, are being offered only to “qualified institutional buyers,” as defined in Rule 144A under the Securities Act, in accordance with Rule 144A under the Securities Act. For further details about eligible offerees and resale restrictions, see the section of the Preliminary Offering Memorandum captioned “Transfer Restrictions.”

Issuer:	Resolute Energy Corporation, a Delaware corporation
Title of Securities:	8⅛% Series B Cumulative Perpetual Convertible Preferred Stock (the “convertible preferred stock”)
Shares Offered:	55,000 shares of convertible preferred stock
Initial Purchaser’s Option to Purchase Additional Shares:	7,500 additional shares of the convertible preferred stock
Distribution:	144A
NYSE Closing Sale Price of the Issuer’s Common Stock on October 4, 2016:	$25.68 per share of common stock
Pricing Date:	October 4, 2016
Settlement Date:	October 7, 2016
Liquidation Preference:	$1,000 per share of convertible preferred stock
Initial Offering Price:	$1,000 per share of convertible preferred stock
Net Proceeds (before expenses):	$52.8 million (or $60.0 million if the Initial Purchaser exercises its option to purchase additional shares in full)
Use of Proceeds:	The Issuer intends to use the net proceeds of this offering, together with borrowings under its Revolving Credit Facility, to fund the cash portion of the purchase price for the Delaware Basin Acquisition. In the event the Delaware Basin Acquisition is not completed, then the Issuer expects to use the net proceeds for general corporate purposes. This offering of convertible preferred stock is not conditioned on completion of the Delaware Basin Acquisition. Accordingly, investors must consider the possibility that such acquisition does not occur and the Issuer obtains none of the benefits expected from such acquisition.

Maturity Date:	The convertible preferred stock has no maturity date and will remain outstanding unless converted by the holders or mandatorily converted or redeemed by the Issuer in the event of an acquisition termination.
Dividends:	Holders of convertible preferred stock are entitled to receive, when, as and if declared by the Issuer’s board of directors, or an authorized committee thereof, cumulative cash dividends at a rate of 8⅛% per annum on the liquidation preference of $1,000 per share of the convertible preferred stock. Dividends will accumulate from the Settlement Date, whether or not any of the Issuer’s agreements prohibit the current payment of dividends, the Issuer has earnings or funds legally available to pay such dividends or the Issuer declares the payment of dividends. To the extent that the Issuer’s board of directors, or an authorized committee thereof, declares (out of funds legally available for the payment in cash) a dividend payable with respect to the convertible preferred stock, the Issuer will pay such dividends in cash on the relevant dividend payment date.
Dividend Payment Dates:	January 15, April 15, July 15 and October 15 of each year, beginning on January 15, 2017
Dividend Record Dates:	January 1, April 1, July 1 and October 1 immediately preceding the relevant dividend payment date.
Conversion Premium:	Approximately 15% above the NYSE closing sale price of the Issuer’s common stock on October 4, 2016
Initial Conversion Rate:	33.8616 shares of the Issuer’s common stock per share of convertible preferred stock
Initial Conversion Price:	Approximately $29.53 per share of the Issuer’s common stock

Acquisition Termination Redemption:	If the Acquisition Agreement relating to the Delaware Basin Acquisition is terminated (other than by consummation of the Delaware Basin Acquisition), the Issuer may redeem all, but not less than all, of the outstanding convertible preferred stock for cash on an acquisition termination redemption date to occur on or prior to April 1, 2017. The acquisition termination redemption price for each share of convertible preferred stock to be redeemed will be equal to the sum of (i) $1,010.00, (ii) accumulated and unpaid dividends on such convertible preferred stock to, but not including, the acquisition termination redemption date and (iii) 90% of the excess, if any, of the acquisition termination redemption conversion value (as defined below) over the initial conversion value (as defined below). Following April 1, 2017, the convertible preferred stock will not be redeemable. The “acquisition termination redemption conversion value” means, with respect to the acquisition termination redemption date, the product of (i) 33.8616, which is the initial conversion rate and (ii) the average of the per share VWAP of the Issuer’s common stock for each day during a 20 consecutive trading day period ending immediately prior to the acquisition termination redemption date. The “initial conversion value” means the product of (i) 33.8616, which is the initial conversion rate and (ii) $25.68, the NYSE closing sale price of the Issuer’s common stock on October 4, 2016.
Mandatory Conversion:	At any time on or after October 15, 2021, the Issuer may give notice of its election to cause all, and not part, of the outstanding shares of the convertible preferred stock to be automatically converted into shares of the Issuer’s common stock, if the closing sale price of the Issuer’s common stock equals or exceeds 150% of the conversion price for at least 20 trading days (whether or not consecutive) in a period of 30 consecutive trading days, including the last trading day of such 30 trading day period, ending on, and including, the trading day immediately preceding the business day on which the Issuer issues a press release announcing the mandatory conversion of the convertible preferred stock (as described in the Preliminary Offering Memorandum), in which case each holder will receive, for each share of convertible preferred stock being converted, a number of shares of the Issuer’s common stock equal to the conversion rate in effect at the time.
Conversion Upon Fundamental Change:	Upon a Fundamental Change, holders of shares of the convertible preferred stock will have the right to convert their shares of convertible preferred stock, in whole or in part, into shares of the Issuer’s common stock during the fundamental change conversion period. If a holder converts its convertible preferred stock, such holder will receive, for each share of the convertible preferred stock surrendered for conversion a number of shares of the Issuer’s common stock equal to the sum of (x) the conversion rate and (y) the make-whole premium, if any, as calculated and described in the Preliminary Offering Memorandum under “—Determination of the Make-Whole Premium.” In addition, such holder will have the right to receive an amount in cash equal to any accumulated and unpaid dividends on such converted shares, whether or not declared prior to the conversion date, for all prior dividend periods ending on or prior to the dividend payment date immediately preceding (or, if applicable, ending on) such date (other than previously declared dividends payable to holders of record as of a prior date); provided that the Issuer is then legally permitted to pay such dividends.
Make-Whole Premium:	The following table sets forth the number of additional shares that will be added to the conversion rate following the date on which the fundamental change occurs or becomes effective (the “effective date”) and prior to the Special Rights End Date (as defined in the Preliminary Offering Memorandum) for each stock price and effective date below:

(1)

The stock prices set forth in the table above (i.e., the column headers) will be adjusted as of any date on which the conversion rate is adjusted under the Preliminary Offering Memorandum. The adjusted stock prices will be equal to the stock prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the conversion rate immediately prior to the adjustment giving rise to the stock price adjustment and the denominator of which is the conversion rate as so adjusted. The number of additional shares in the table above will be adjusted in the same manner and at the same time as the conversion rate.

	The exact stock price and effective date may not be set forth on the table, in which case:
	· if the stock price is between two stock prices on the table or the effective date is between two effective dates on the table, the number of additional shares will be determined by a straight-line interpolation between the number of additional shares set forth for the higher and lower stock prices or the earlier and later effective dates, as applicable, based on a 365-day year;
	· if the stock price is in excess of $100.00 per share (subject to adjustment in the same manner as the stock prices), no additional shares will be added to the conversion rate; and
	· if the stock price is less than $25.68 per share (subject to adjustment in the same manner as the stock prices), no additional shares will be added to the conversion rate.
CUSIP/ISIN Numbers:	76116A 405/US76116A4058
Listing:	Prior to this offering, there has been no public market for the convertible preferred stock. The Issuer does not intend to apply to list the convertible preferred stock on any securities exchange or any automated dealer quotation system.
Book-Running Manager:	BMO Capital Markets Corp.

Changes to Information in the Preliminary Offering Memorandum

In addition to pricing information set forth above, the Preliminary Offering Memorandum will be updated to reflect the following:

As the size of the offering has increased from 50,000 shares of convertible preferred stock (or 57,500 shares of convertible preferred stock if the initial purchaser exercises its option to purchase additional shares in full) to 55,000 shares of convertible preferred stock (or 62,500 shares of convertible preferred stock if the initial purchaser exercises its option to purchase additional shares in full), all corresponding references in the Preliminary Offering Memorandum related to the offering size are hereby updated. References in the Preliminary Offering Memorandum related to expected borrowings under the Revolving Credit Agreement in relation to the Delaware Basin Acquisition are hereby updated.

As a result of the increase in the size of the offering, the Issuer intends to decrease its expected borrowings under its Revolving Credit Agreement to $38.2 million (instead of $43 million) to fund the cash portion of the purchase price for the Delaware Basin Acquisition.

As of June 30, 2016, on a pro forma basis after giving effect to this offering, the Delaware Basin Acquisition and repayments made on the Revolving Credit Facility since June 30, 2016, (i) the Issuer would have had total indebtedness of $566.5 million, $166.5 million of which would have been secured, and (ii) the Issuer would have had $63.2 million available for borrowing under the Revolving Credit Facility.

c/o BMO Capital Markets Corp.

▇ ▇▇▇▇▇ ▇▇▇▇▇▇

▇▇▇▇ ▇▇▇▇▇

▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

The undersigned understands that you and certain other firms (the “Initial Purchasers”) propose to enter into a Purchase Agreement (the “Purchase Agreement”) providing for the purchase by the Initial Purchasers of shares (the “Securities”) of Series B Cumulative Perpetual Convertible Preferred Stock, with an initial liquidation preference of $1,000.00 per share, of Resolute Energy Corporation, a Delaware corporation (the “Company”), and that the Initial Purchasers propose to reoffer the Securities in accordance with Rule 144A or another applicable exemption under the Securities Act of 1933, as amended (the “Offering”). The Securities will be convertible, subject to certain conditions set forth in the Certificate of Designations establishing the Securities, for shares of common stock of the Company, par value $0.0001 per share (the “Common Stock”), in accordance with the terms of the Securities.

In consideration of the execution of the Purchase Agreement by the Initial Purchasers, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of BMO Capital Markets Corp., on behalf of the Initial Purchasers, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock (including, without limitation, shares of Common Stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission, and shares of Common Stock that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for Common Stock, (2) 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 shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock or any other securities of the Company or (4) publicly disclose the intention to do any of the foregoing, for a period commencing on the date hereof and ending on the 75th day after the date of the Final Memorandum relating to the Offering.

The foregoing paragraph shall not apply to (a) transactions relating to shares of Common Stock or other securities acquired in the open market after the completion of the Offering, (b) bona fide gifts of shares of Common Stock in an aggregate amount not exceeding 25,000 shares of Common Stock, (c) sales or other dispositions of shares of any class of the Company’s capital stock, in each case that are made exclusively between and among the undersigned or members of the undersigned’s family, or affiliates of the undersigned, including its partners (if a partnership) or members (if a limited liability company); provided that it shall be a condition to any transfer pursuant to this clause (c) that (i) the transferee agrees to be bound by the terms of this Lock-Up Letter Agreement (including, without limitation, the restrictions set forth in the preceding sentence) to the same extent as if the transferee were a party hereto, and (ii) the undersigned notifies BMO Capital Markets Corp. at least two business days prior to the proposed transfer or disposition; (d) the exercise of warrants or the exercise of stock options or the vesting of other outstanding equity awards granted pursuant to the Company’s stock option/incentive plans or otherwise outstanding on the date hereof; provided, that the restrictions shall apply to shares of Common Stock issued upon such exercise or conversion, and (e) the transfer of shares of Common Stock to the Company in satisfaction or payment of any exercise price or to satisfy any tax withholding obligations with respect to equity awards granted under any existing employee benefit plan of the Company.

In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if the Company notifies the Initial Purchasers that it does not intend to proceed with the Offering, if the Purchase Agreement does not become effective, or if the Purchase Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities, the undersigned will be released from its obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Company and the Initial Purchasers will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to a Purchase Agreement, the terms of which are subject to negotiation between the Company and the Initial Purchasers.

This Lock-Up Letter Agreement shall automatically terminate upon the earliest to occur, if any, of (1) the termination of the Purchase Agreement before the sale of any Securities to the Initial Purchasers or (2) October 15, 2016, in the event that the Purchase Agreement has not been executed by that date.

[Signature page follows]

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.


Very truly yours,
