(1)	The Reporting Person directly owns 1,385,100 shares of Common Stock issued in the acquisition (the "Acquisition") completed pursuant to that certain Purchase and IPO Reorganization Agreement (the "Purchase Agreement"), dated as of August 2, 2009, as amended, among Resolute Energy Corporation, Hicks Acquisition Company I, Inc., Resolute Holdings, LLC and others and registered in the Issuer's Form S-4 Registration Statement (333-161076). With the exception of 100 shares which the Reporting Person owns with no limitations, these shares of Common Stock are subject to forfeiture unless at any time prior to five years from the closing of the Acquisition, either (a) the closing sale price of Common Stock exceeds $15.00 per share for 20 trading days in any 30 day trading period beginning 90 days after the closing of the Acquisition, or (b) a change in control event occurs in which Common Stock is valued at greater than $15.00 per share.

	The Reporting Person also directly owns 2,333,333 warrants (the "Sponsor Warrants") acquired in connection with the Acquisition. Each Sponsor Warrant entitles the holder to purchase one share of Common Stock at a price of $13.00 per share commencing on the date of the closing of the Acquisition and ending five years from the Acquisition Closing Date.

	Thus, for purposes of this Schedule 13D, the Reporting Person is deemed to directly beneficially own 3,718,433 shares of Common Stock even though certain of the shares of Common Stock directly owned by the Reporting Person are subject to the limitations set forth above.

	The Reporting Person also directly owns 4,600,000 warrants (the "Founders' Warrants") issued in the Acquisition. Each Founders’ Warrant entitles the holder to purchase one share of Common Stock at a price of $13.00 per share, but such shares are not deemed to be beneficially owned as of the date of this filing and are therefore excluded from this Schedule 13D. The warrant exercise period of Founders' Warrants commences any time after the Closing Price (as defined in the Purchase Agreement) of the Common Stock exceeds $13.75 for any 20 days within any 30 day trading period prior to September 25, 2014.

NGP VII (and NGP-VII Income Co-Investment Opportunities, L.P.) received the securities it is deemed to directly beneficially own in the Issuer reported in this Schedule 13D as a result of a pro rata distribution without consideration of such securities from Resolute Holdings to its members on December 21, 2009 in accordance with the limited liability company operating agreement of Resolute Holdings.

Resolute Holdings received the securities it is deemed to directly beneficially own in the Issuer reported in this Schedule 13D in the acquisition (the "Acquisition") completed pursuant to that certain Purchase and IPO Reorganization Agreement (the "Purchase Agreement"), dated as of August 2, 2009, as amended, among Resolute Energy Corporation, Hicks Acquisition Company I, Inc., Resolute Holdings and others and registered in the Issuer's Form S-4 Registration Statement (333-161076).

Item 4. Purpose of Transaction.

The Reporting Persons acquired the Common Stock reported herein solely for investment purposes. The Reporting Persons may make additional purchases of Common Stock either in the open market or in private transactions depending on the Reporting Persons’ business, prospects and financial condition, the market for the Common Stock, general economic conditions, stock market conditions and other future developments.

Except as described in this Item 4, the Reporting Persons do not have, as of the date of this Schedule 13D, any plans or proposals that relate to or would result in any of the actions or events specified in clauses (a) through (j) of Item 4 of Schedule 13D. The Reporting Persons may change their plans or proposals in the future. In determining from time to time whether to sell the Common Stock reported as beneficially owned in this Schedule 13D (and in what amounts) or to retain such securities, the Reporting Persons will take into consideration such factors as they deem relevant, including the business and prospects of the Issuer, anticipated future developments concerning the Issuer, existing and anticipated market conditions from time to time, general economic conditions, regulatory matters, and other opportunities available to the Reporting Persons.

(a)-(b)

(i)

Kenneth A. Hersh does not directly own any Common Stock. Kenneth A. Hersh is an Authorized Member of GFW VII, L.L.C., the general partner of G.F.W. Energy VII, L.P., which is the general partner of NGP VII, and thus may be deemed to possess shared voting and dispositive powers with respect to all shares of Common Stock that NGP VII is the sole record owner of (6,276,166 shares (11.81%)), as well as all shares of Common Stock that NGP VII may be deemed to beneficially own (289,719 shares (0.55%) directly owned by NGP VII Co-Investment Opportunities, L.P. and 3,718,433 shares (6.7%) deemed beneficially owned by Resolute Holdings). Therefore, Kenneth A. Hersh may be deemed to possess shared voting and dispositive powers with respect to 10,284,318 shares (18.53%) of Common Stock.

		(ii)	NGP VII is the sole record owner of, and has the sole power to vote and dispose of 6,276,166 shares (11.81%) of Common Stock.

			NGP VII owns 100% of NGP Income Management, L.L.C which serves as the general partner of NGP-VII Income Co-Investment. NGP VII may thus be deemed to possess shared voting and dispositive powers with respect to all of the shares of Common Stock owned directly by NGP-VII Income Co-Investment (289,719 shares (0.55%)).

		NGP VII and NGP-VII Income Co-Investment Opportunities, L.P. have an approximately 71% membership interest in Resolute Holdings subject to certain adjustments in the future that could decrease such interest. Thus, NGP VII may be deemed to possess shared voting and dispositive powers with respect to all of the shares of Common Stock deemed beneficially owned by Resolute Holdings (3,718,433 shares (6.7%)).

		Therefore, NGP VII may be deemed to possess sole and shared voting and dispositive powers with respect to 10,284,318 shares (18.53%) of Common Stock.

	(iii)	Resolute Holdings is the sole record owner of, and has the sole power to vote and dispose of 1,385,100 shares (2.5%) of Common Stock. With the exception of 100 shares which Resolute Holdings owns with no limitations, these shares of Common Stock are subject to forfeiture unless at any time prior to five years from the closing of the Acquisition, either (a) the closing sale price of Common Stock exceeds $15.00 per share for 20 trading days in any 30 day trading period beginning 90 days after the closing of the Acquisition, or (b) a change in control event occurs in which Common Stock is valued at greater than $15.00 per share.

	Resolute Holdings also directly owns 2,333,333 warrants (the "Sponsor Warrants") acquired in connection with the Acquisition. Each Sponsor Warrant entitles the holder to purchase one share of Common Stock at a price of $13.00 per share commencing on the date of the closing of the Acquisition and ending five years from the Acquisition Closing Date.

	Thus, for purposes of this Schedule 13D, Resolute Holdings is deemed to directly beneficially own 3,718,433 shares (6.7%) of Common Stock even though certain of the shares of Common Stock directly owned by Resolute Holdings are subject to the limitations set forth above.

	Resolute Holdings also directly owns 4,600,000 warrants (the "Founders' Warrants") issued in the Acquisition. Each Founder’s Warrant entitles the holder to purchase one share of Common Stock at a price of $13.00 per share, but such shares are not deemed to be beneficially owned as of the date of this filing and are therefore excluded from this Schedule 13D. The warrant exercise period of Founders' Warrants commences any time after the Closing Price (as defined in the Purchase Agreement) of the Common Stock exceeds $13.75 for any 20 days within any 30 day trading period prior to September 25, 2014.

The above Reporting Persons disclaim beneficial ownership of the reported securities except to the extent of their pecuniary interests therein, and this report shall not be deemed an admission that the Reporting Persons are the beneficial owners of the reported securities for purposes of Section 16 or for any other purpose.

(c)	There have been no reportable transactions with respect to the Common Stock within the last 60 days by the Reporting Persons except for the distribution of shares of Common Stock from Resolute Holdings to its members as reported on this Schedule 13D.

(d)	No person other than the Reporting Persons or the managers of Resolute Holdings indentified on Schedule A, has the right to receive or the power to direct the receipt of distributions from, or the proceeds from the sale of, the Common Stock being reported on this Schedule 13D.

(e)	Not applicable.
