the number of Shares that may be issued with respect to Awards granted under the
Plan shall be 2,267,270. If an Award is forfeited or otherwise lapses, expires,
terminates or is canceled without the actual delivery of Shares, then the Shares

by the Company.

SECTION 5. ELIGIBILITY.

     Any Employee shall be eligible to be designated a Participant by the
Committee.

SECTION 6. AWARDS.

     (a) Restricted Stock. Awards of Restricted Stock with respect to the total
number of Shares that may be issued under the Plan shall be granted on the
Effective Date, and, subject to the provisions of the Plan, the Committee shall
have the authority to determine the Participants to whom Restricted Stock shall
be granted, the number of Shares of Restricted Stock to be granted to each such
Participant, the duration of the Restricted Period, the conditions under which
the Restricted Stock may be forfeited to the Company, and the other terms and
conditions of such Awards.

          (i) Dividends. Dividends paid on Restricted Stock may be paid directly
     to the Participant, may be subject to risk of forfeiture and/or transfer
     restrictions during any period established by the Committee or sequestered
     and held in a bookkeeping cash account (with or without interest) or
     reinvested on an immediate or deferred basis in additional shares of Common
     Stock, which credit or shares may be subject to the same restrictions as
     the underlying Award or such other restrictions, all as determined by the
     Committee in its discretion, as provided in the Award Agreement.

          (ii) Registration. Any Restricted Stock may be evidenced in such
     manner as the Committee shall deem appropriate, including, without
     limitation, book-entry registration or issuance of a stock certificate or
     certificates. In the event any stock certificate is issued in respect of
     Restricted Stock granted under the Plan, such certificate

                                       -3-

<PAGE>

     shall be registered in the name of the Participant and shall bear an
     appropriate legend referring to the terms, conditions, and restrictions
     applicable to such Restricted Stock.

          (iii) Forfeiture and Restrictions Lapse. Except as otherwise
     determined by the Committee or the terms of the Award Agreement that
     granted the Restricted Stock, upon the termination of a Participant's
     employment for any reason during the applicable Restricted Period, all
     Restricted Stock shall be forfeited by the Participant without payment and
     re-acquired by the Company. The Committee may, when it finds that a waiver
     would be in the best interests of the Company, waive in whole or in part
     any or all remaining restrictions with respect to such Participant's
     Restricted Stock.

          (iv) Transfer Restrictions. During the Restricted Period, Restricted
     Stock will be subject to such limitations on transfer as necessary to
     comply with Section 83 of the Code.

     (b) General.

          (i) Awards May Be Granted Separately or Together. Awards may, in the
     discretion of the Committee, be granted either alone or in addition to, in
     tandem with, any award granted under any other plan of the Company or any
     Parent Entity or Subsidiary. Awards granted in addition to or in tandem
     with other awards granted under any other plan of the Company or any Parent
     Entity or Subsidiary may be granted either at the same time as or at a
     different time from the grant of such other Awards or awards.

          (ii) Limits on Transfer of Awards. No Award and no right under any
     such Award may be assigned, alienated, pledged, attached, sold or otherwise
     transferred or encumbered by a Participant other than by will or by the
     laws of descent and distribution, and any such purported prohibited
     assignment, alienation, pledge, attachment, sale, transfer or encumbrance
     shall be void and unenforceable against the Company or any Parent Entity or
     Subsidiary. To the extent specifically approved in writing by the
     Committee, an Award may be transferred to immediate family members or
     related family trusts, limited partnerships or similar entities or other
     Persons on such terms and conditions as the Committee may establish or
     approve in its sole discretion.

          (iii) Terms of Awards. The terms of each Award shall be as determined
     by the Committee.

          (iv) Share Restrictions. All Shares or other securities of the Company
     delivered under the Plan pursuant to any Award shall be subject to such
     stop transfer orders and other restrictions as the Committee may deem
     advisable under the Plan or the rules, regulations, and other requirements
     of the SEC, any stock exchange upon which such Shares or other securities
     are then listed, and any applicable federal or state laws, and, if
     certificates are issued for the Shares, the Committee may cause a legend or
     legends to be put on any such certificates to make appropriate reference to
     such restrictions.

                                       -4-

<PAGE>

          (v) Consideration for Grants. Awards may be granted for no cash
     consideration or for such consideration as the Committee determines
     including, without limitation, such minimal cash consideration as may be
     required by applicable law.

          (vi) Delivery of Shares or other Securities and Payment by Participant
     of Consideration. No Shares or other securities shall be delivered pursuant
     to any Award until payment in full of any amount required to be paid
     pursuant to the Plan or the applicable Award Agreement (including, without
     limitation, any tax withholding) is received by the Company. Such payment
     may be made by such method or methods and in such form or forms as the
     Committee shall determine, including, without limitation, cash, Shares,
     other securities, or other property, withholding of Shares, or any
     combination thereof, provided that the combined value, as determined by the
     Committee, of all cash and cash equivalents and the Fair Market Value of
     any such Shares or other property so tendered to the Company, as of the
     date of such tender, is at least equal to the full amount required to be
     paid pursuant to the Plan or the applicable Award Agreement to the Company.

          (vii) Unusual Transactions or Events. In the event of any distribution
     (whether in the form of cash, Shares, other securities, or other property),
     recapitalization, reorganization, merger, spin-off, split-off, split-up,
     consolidation, combination, repurchase, or exchange of Shares or other
     securities of the Company, or other relevant corporate transaction or event
     or any unusual or nonrecurring transactions or events affecting the
     Company, or any affiliate of the Company, and whenever the Committee
     determines that action is appropriate in order to prevent the dilution or
     enlargement of the benefits or potential benefits intended to be made
     available under the Plan or with respect to any Award under the Plan, to
     facilitate such transactions or events, the Committee, in its sole
     discretion and on such terms and conditions as it deems appropriate, may
     take any one or more of the following actions:

               (A) To provide that such Award be assumed by the successor or
          survivor corporation, or a parent or subsidiary thereof, or shall be
          substituted for by similar rights or awards covering the stock of the
          successor or survivor corporation, or a parent or subsidiary thereof,
          with appropriate adjustments as to the number and kind of shares; and

               (B) To provide that such Award shall be payable or fully vested
          with respect to all Shares covered thereby, notwithstanding anything
          to the contrary in the Plan or the applicable Award Agreement.

SECTION 7. AMENDMENT.

     Except to the extent prohibited by applicable law and unless otherwise
expressly provided in an Award Agreement or in the Plan:

          (i) Amendments to the Plan. The Board or the Committee may amend or
     alter the Plan without the consent of any stockholder, Participant, other
     holder or beneficiary of an Award, or other Person; provided, however, that
     no such amendment or

                                       -5-

<PAGE>

     alteration shall materially adversely affect the rights of a Participant
     under an Award without the consent of such Participant.

          (ii) Amendments to Awards. Subject to clause (i) above, the Committee
     may waive any conditions or rights under, amend any terms of, or alter any
     Award theretofore granted, provided no change in any Award shall materially
     adversely affect the rights of a Participant under the Award without the
     consent of such Participant.

          (iii) Compliance with Applicable Law. Notwithstanding the foregoing,
     the Committee may make any amendment to the Plan or an Award Agreement that
     it believes necessary or helpful to comply with any applicable law,
     including without limitation, Section 409A of the Code.

SECTION 8. GENERAL PROVISIONS.

     (a) No Rights to Awards. No Participant or other Person shall have any
claim to be granted any Award, there is no obligation for uniformity of
treatment of Participants, or holders or beneficiaries of Awards and the terms
and conditions of Awards need not be the same with respect to each recipient.

     (b) No Right to Employment or Retention. The grant of an Award shall not be
construed as giving a Participant the right to be retained in the employ of the
Company or any Parent Entity or Subsidiary or under any other service contract
with the Company or any Parent Entity or Subsidiary. Further, the Company or a
Parent Entity or Subsidiary may at any time dismiss a Participant from
employment free from any liability or any claim under the Plan, unless otherwise
expressly provided in the Plan, in any Award Agreement or any other agreement or
contract between the Company or a Parent Entity or Subsidiary and the affected
Participant. If a Participant's employer was a Parent Entity or Subsidiary and
ceases to be a Parent Entity or Subsidiary, such Participant shall be deemed to
have terminated employment for purposes of the Plan, unless specifically
provided otherwise in the Award Agreement.

     (c) Governing Law. The validity, construction, and effect of the Plan and
any rules and regulations relating to the Plan shall be determined in accordance
with the laws of the State of Texas and applicable federal law.

     (d) Severability. If any provision of the Plan or any Award is or becomes
or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as
to any Person or Award, or would disqualify the Plan or any Award under any law
deemed applicable by the Committee, such provision shall be construed or deemed
amended to conform to the applicable laws, or if it cannot be construed or
deemed amended without, in the determination of the Committee, materially
altering the intent of the Plan or the Award, such provision shall be stricken
as to such jurisdiction, Person or Award and the remainder of the Plan and any
such Award shall remain in full force and effect.

     (e) Other Laws. The Committee may refuse to issue or transfer any Shares or
other consideration under an Award, permit the exercise of an Award and/or the
satisfaction of its tax withholding obligation in the manner elected by the
Participant, holder or beneficiary if, acting in its sole discretion, it
determines that the issuance of transfer or such Shares or such other

                                       -6-

<PAGE>

consideration, the manner of exercise or satisfaction of the tax withholding
obligation might violate any applicable law or regulation, including without
limitation, the Sarbanes-Oxley Act, or entitle the Company to recover the same
under Section 16(b) of the Exchange Act, and any payment tendered to the Company
by a Participant, other holder or beneficiary in connection with the exercise of
such Award shall be promptly refunded or refused, as the case may be, to the
relevant Participant, holder or beneficiary.

     (f) No Trust or Fund Created. Neither the Plan nor the Award shall create
or be construed to create a trust or separate fund of any kind or a fiduciary
relationship between the Company or any Parent Entity or Subsidiary and a
Participant or any other Person. To the extent that any Person acquires a right
to receive payments from the Company or any Parent Entity or Subsidiary pursuant
to an Award, such right shall be no greater than the right of any general
unsecured creditor of the Company or any Parent Entity or Subsidiary.

     (g) No Fractional Shares. No fractional Shares shall be issued or delivered
pursuant to the Plan or any Award, and the Committee shall determine whether
cash, other securities, or other property shall be paid or transferred in lieu
of any fractional Shares or whether such fractional Shares or any rights thereto
shall be cancelled, terminated, or otherwise eliminated.

     (h) Headings. Headings are given to the Section and subsections of the Plan
solely as a convenience to facilitate reference. Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
the plan or any provision thereof.

SECTION 9. EFFECTIVE DATE OF AND TERM OF THE PLAN.

     The Plan shall become effective as of the Effective Date. Further, no
Awards may be made after the Effective Date. However, unless otherwise expressly
provided in the Plan or in an applicable Award Agreement, the Plan shall remain
in effect until all Awards granted under the Plan have vested or been forfeited.

     1. Notice of Grant. Subject to the terms and conditions of the Plan and
this Agreement and subject to your execution of this Agreement within 14 days
after the Date of Grant, you are hereby granted pursuant to the Mariner Energy,
Inc. Equity Participation Plan (the "Plan") the above number of restricted
shares of Common Stock ("Restricted Stock") of Mariner Energy, Inc. (the
"Company"). If you fail to execute this Agreement within 14 days after the Date
of Grant, the grant of Restricted Stock and this Agreement shall be void as of
the Date of Grant.

     2. Vesting of Restricted Stock. Subject to the further provisions of this
Agreement, the shares of Restricted Stock shall become 100% vested upon the
earlier of: (i) the later to occur of: (A) the first anniversary of the Date of
Grant and (B) the Public Sale Date (as defined below) and (ii) the second
anniversary of the Date of Grant. For purposes of this Agreement, the "Public
Sale Date" shall mean the earlier to occur of: (a) the 90th day following the
date on which the Common Stock is listed on the New York Stock Exchange or
admitted to trading and quoted on the Nasdaq National Market or Nasdaq SmallCap
Market and (b) the first date on which both of the following conditions are met:
(1) a registration statement covering the resale of the Restricted Stock has
been declared effective by the Securities and Exchange Commission, and no stop
order suspending the effectiveness of such registration statement is in effect
and (2) the Common Stock is listed on the New York Stock Exchange or admitted to
trading and quoted on the Nasdaq National Market or Nasdaq SmallCap Market;
provided, however, that if upon the occurrence of any event described in clauses
(a) and (b) the Restricted Stock is subject to restrictions on resale as a
result of a lock-up agreement or arrangement applicable to such shares in
connection with a public offering of stock, the Public Sale Date shall be the
earlier of the first business day following the date of expiration of the
lock-up period and a date 181 days from the date the lock-up period commenced.

     Notwithstanding the above vesting schedule, but subject to the further
provisions hereof, upon the occurrence of the following events the unvested
shares of Restricted Stock shall vest or be forfeited as provided below:

          (a) Disability. If you are entitled to benefits under Section 7(d) of
     your Employment Agreement entered into with the Company, dated February 7,
     2005 ("Employment Agreement") or if the Employment Agreement has
     terminated, your employment with the Company terminates by reason of a
     disability that entitles you to benefits under the Company's or an
     affiliate's long-term disability plan, the unvested shares of Restricted
     Stock shall become fully vested.

<PAGE>

          (b) Death. If you die while in the employ of the Company, the unvested
     shares of Restricted Stock shall become fully vested.

          (c) By the Company other than for Cause. If your employment with the
     Company is terminated by the Company for any reason other than for Cause
     (as defined below), the unvested shares of Restricted Stock shall become
     fully vested. For purposes of this Section 2, the term "Cause" shall have
     the meaning ascribed to such term in your Employment Agreement, or if the
     Employment Agreement has terminated, shall mean (i) a material failure to
     perform your duties, (ii) your conviction of or plea of nolo contendere for
     any felony or any misdemeanor involving moral turpitude, dishonesty, fraud
     or breach of trust, (iii) your willful engagement in gross misconduct in
     the performance of your duties, your substance abuse, (iv) your
     misappropriation of funds, or (v) your disparagement of the Company or any
     affiliate or any of their respective managements or employees.

          (d) Termination for Cause or other than for Good Reason. Except as
     otherwise provided in Section 2(f) below, if your employment with the
     Company is terminated by the Company for Cause or by you other than for a
     Good Reason (as defined below), the unvested shares of Restricted Stock
     shall be forfeited without consideration. For purposes of this Section 2,
     the term "Good Reason" shall have the meaning ascribed to such term in your
     Employment Agreement, or if the Employment Agreement has terminated, shall
     mean (i) a material adverse change in the nature or scope of your
     authorities, powers, duties and functions performed; (ii) a material
     reduction in your base salary or in the cash bonus opportunities made
     available to you, excluding opportunities under (A) any plan, program,
     arrangement or agreement providing for compensation in the form of
     overriding royalty interests or income from overriding royalty interests,
     (B) any equity-based compensation plans, programs, arrangements or
     agreements, including, but not limited to, stock options, and (C) 401(k)
     and profit-sharing plans; or (iii) your permanent place of employment with
     the Company is changed to a location that is more than 50 miles from your
     location prior to such change.

          (e) For Good Reason. If your employment with the Company is terminated
     by you for a Good Reason, the unvested shares of Restricted Stock shall
     become fully vested.

          (f) Change of Control. Upon the occurrence of a Change of Control (as
     defined in your Employment Agreement) that occurs while you are employed by
     the Company or within nine months following a termination of your
     employment with the Company that entitles you to severance under Section
     7(c) of your Employment Agreement, the unvested shares of Restricted Stock
     shall become fully vested.

     For purposes of this Agreement, "employment with the Company" shall include
being an employee of the Company or a Parent Entity or Subsidiary.

     All shares of Restricted Stock that are not vested on or before your
termination of employment with the Company as provided above shall be
automatically cancelled and forfeited without consideration upon your
termination, except that if your employment with the Company terminates and you
are entitled to severance benefits under Section 7(c) of your Employment

                                       -2-

<PAGE>

Agreement, then the unvested shares of Restricted Stock, if any, shall not be
cancelled or forfeited until the date following the date that is nine months
after your termination from the Company. If a Change of Control occurs during
such nine-month period, the unvested shares of Restricted Stock shall become
vested on such Change of Control. Notwithstanding anything in this Agreement
seemingly to the contrary, no additional vesting shall occur during such
nine-month period except upon a Change of Control as provided above.

     Any distributions on a share of Restricted Stock shall be held by the
Company without interest until the Restricted Stock with respect to which the
distribution was made becomes vested or is forfeited and then such withheld
distribution shall be paid or forfeited, as the case may be.

     3. Book Entry. A book entry evidencing the shares of Restricted Stock shall
be made in your name in the books of the Company maintained by its transfer
agent, pursuant to which you shall have all of the rights of a shareholder of
the Company (except with respect to distributions as provided above) with
respect to the shares of Restricted Stock, including, without limitation, voting
rights. The book entry shall reflect the restrictions on transfer set forth in
Section 4 below. Upon vesting, the Company will cause the book entry to be
amended to remove any restrictions (except for any restrictions required
pursuant to applicable securities laws or any other agreement to which you are a
party) with respect to the shares of Restricted Stock that have vested.

     4. Nontransferability of Restricted Stock. Prior to vesting, you may not
sell, transfer, pledge, exchange, hypothecate or dispose of the shares of
Restricted Stock in any manner otherwise than by will or by the laws of descent
or distribution. A breach of the terms of this Agreement shall cause a
forfeiture of all shares of unvested Restricted Stock.

     5. Entire Agreement; Governing Law. The Plan is incorporated herein by
reference. The Plan, this Agreement, and your Employment Agreement constitute
the entire agreement of the parties with respect to the subject matter hereof
and thereof and supersede in their entirety all prior undertakings and
agreements of the Company and you with respect to the subject matter hereof and
thereof, and may not be modified adversely to your interest except by means of a
writing signed by the Company and you. This Agreement is governed by the
internal substantive laws, but not the choice of law rules, of the State of
Texas.

     6. Withholding of Tax. To the extent that the receipt of the shares of
Restricted Stock or the vesting thereof results in income to you for federal,
state or other tax purposes, unless the Company agrees otherwise, you shall
either pay the Company an amount of cash equal to the Company's tax withholding
obligations or have the Company withhold and cancel from the number of shares of
Restricted Stock awarded you such number of shares of Restricted Stock as the
Company determines to be necessary to satisfy the tax required to be withheld by
the Company; provided however, that if you fail to satisfy the Company's tax
withholding obligations, the Company, in its sole discretion, may withhold and
cancel from the number of shares of Restricted Stock awarded you such number of
shares of Restricted Stock as it determines to be necessary to satisfy the tax
required to be withheld by the Company.

     7. Amendment. Except as provided below, this Agreement may not be modified
in any respect by any verbal statement, representation or agreement or by any
employee, officer, or representative of the Company or by any written agreement
unless signed by you and by an

officer of the Company who is expressly authorized by the Company to execute
such document. Notwithstanding anything in the Plan or this Agreement to the
contrary, if the Committee determines that the terms of this grant do not, in
whole or in part, satisfy the requirements of Section 409A of the Internal
Revenue Code, to the extent applicable, the Committee, in its sole discretion,
may unilaterally modify this Agreement in such manner as it deems appropriate to
comply with such section and any regulations or guidance issued thereunder.

     8. Status of Stock. You agree that the shares of Restricted Stock issued
under this Agreement will not be sold or otherwise disposed of in any manner
that would constitute a violation of the terms and provisions of any applicable
federal or state securities laws. You also agree that (i) the book entry made
(or the certificates, if any are issued) representing the shares of Restricted
Stock may bear such restriction, restrictions, legend or legends as the
Committee deems appropriate, (ii) the Company may refuse to register the
transfer of the Restricted Stock on the stock transfer records of the Company if
such proposed transfer would, in the opinion of counsel satisfactory to the
Company, be contrary to the terms and provisions of any applicable securities
law, and (iii) the Company may give related instructions to its transfer agent,
if any, to stop registration of the transfer of the Restricted Stock.

     9. General. You agree that the shares of Restricted Stock are granted under
and governed by the terms and conditions of the Plan and this Agreement. In the
event of any conflict, the terms of the Plan shall control. Unless otherwise
defined herein, the terms defined in the Plan shall have the same defined
meanings in this Restricted Stock Agreement.
