2005  INTRODUCTION  Building Materials Corporation of America, a Delaware corporation
(hereinafter referred to as the Corporation) established the BUILDING
MATERIALS CORPORATION OF AMERICA 2001 LONG-TERM INCENTIVE PLAN (hereinafter
referred to as the Plan) to permit the grant of Incentive Units (as hereafter
defined) to eligible employees of the Corporation and the Subsidiaries (as
hereafter defined).  The Plan provides
for a long term incentive system that supports the Corporations business
strategy and emphasizes pay-for performance by tying reward opportunities to
corporate goals.  The Plans original
effective date was December 31, 2000 (the Effective Date).  The Corporation hereby amends and restates
the Plan, effective as of January 1, 2005, to comply with the
provisions of Section 409A of the Code (hereinafter defined) and
regulations and guidance issued thereunder (Section 409A).  The Plan shall be interpreted and
administered consistent with this intent and shall apply to all outstanding and
prospective Incentive Unit awards.  I.  DEFINITIONS  For
purposes of this Plan, the following terms shall be defined as follows unless
the context clearly indicates otherwise:  (a)Affiliate
shall mean any member of the group of corporations, trades or businesses
or other organizations comprising the controlled group with the
Corporation.  For purposes of the foregoing,
whether an entity is affiliated shall be determined pursuant to the controlled
group rules of Code Section 414; however, a 50% minimum ownership
threshold shall be used when applying the applicable provisions of (A) Code
Section 1563 for determining a controlled group of corporations under Code
Section 414(b), and (B) Treasury Regulation Section 1.414(c)-2
for determining the trades or businesses that are under common control under
Code Section 414(c).  (b)Beneficiary
shall mean one or more persons, trusts, estates or other entities designated by
the Employee in accordance with Section V that are entitled to receive
payment of a Gain under this Plan upon the death of an Employee.  (c)Board of
Directors or Board
shall mean the Board of Directors of the Corporation. All determinations by the
Board shall be made in good faith in its sole discretion and shall be binding
and conclusive.  (d)Book Value

cumulative consolidated net income or loss of the Corporation for the period January 1,
2001 through the date of determination and (iii) $2,480,625 multiplied by  1


the number of full fiscal quarters of the Corporation that have ended
after December 31, 2000 but on or before the date of determination
(such product representing a 15% per annum credit on the aggregate dividends or
distributions made by the Corporation to its stockholders during the period of October 1,
1997 through December 31, 2000), and excluding, to the extent occurring
after December 31, 2000, the impact of (A) nonrecurring operating
losses, nonrecurring operating gains and extraordinary items, each as
determined in accordance with generally accepted accounting principles, (B) any
charge incurred after December 31, 2000 relating to asbestos-related
liabilities, (C) net after-tax gains or losses in respect of dispositions
of assets by the Corporation other than in the ordinary course of business, (D) any
charges relating to amortization of goodwill and other intangibles arising from
the management buy-out of GAF Corporation in March 1989, and (E) such
other items as the Board of Directors may determine to be extraordinary or
unusual and the impact of which should not be included in consolidated net
income or loss, as the case may be, for the purposes of computing Book Value.
There shall be deducted from Book Value an amount equal to a 15% per annum
charge on the aggregate capital contributions made to the Corporation by its
stockholders during the period commencing January 1, 2001 and ending with
the date of determination (the Period), amounts actually received by the
Corporation during the Period for shares of its capital stock and, to the
extent not actually charged against the net income of the Corporation, on the
outstanding principal amount of loans and other advances made to the
Corporation by affiliates (excluding Subsidiaries of the Corporation) during
the Period. There shall be added to Book Value a 15% per annum credit on the
aggregate dividends or distributions (including redemption of shares of its
capital stock) made by the Corporation to its stockholders during the Period
and, to the extent interest is not actually imputed to the Corporation in respect
of such amounts, on the outstanding principal amount of loans and other
advances made by the Corporation to affiliates (excluding Subsidiaries of the
Corporation) during the Period. Any adjustments to Book Value (including the
15% charge and credit referred to in the preceding two sentences) shall take
into account the tax effect, if any, associated therewith. If the Corporations
common stock is converted into or exchanged for other securities or property
pursuant to a recapitalization, stock split, combination, reorganization,
merger, exchange or similar transaction, or if a sale of all or substantially
all of, the common stock of the Corporation shall occur or be pending, Book
Value, the Incentive Units and the terms hereof shall be modified by the Board

eligibility of any individual to participate in the Plan, and to require any
person to furnish any information as it may request to properly administer the
Plan as a condition to that person receiving any benefit under the Plan;  (iv)          to compute the amount of
benefits that are payable to any Employee or Beneficiary in accordance with the
provisions of the Plan, and to determine the person or persons to whom those

the Committee in good faith, but excluding the gross negligence or willful
misconduct of any member.  Such
indemnification shall include attorneys fees and other costs and expenses
reasonably incurred in defense of any action brought by reason of any such act
or failure to act.  III.  ELIGIBILITY TO PARTICIPATE  Each
individual who is an Employee shall be initially eligible to participate in the
Plan.  No individual shall automatically
be entitled to receive a grant of Incentive Units solely because he is
classified as an Employee.  6


IV.  INCENTIVE UNITS  (a)Grant of Incentive Units. The
Committee may, in its sole discretion, grant Incentive Units to any one or more
Employees.  The number of Incentive Units
granted to each Employee shall be determined by the Committee in its sole discretion.  Incentive Units may only be granted as of a
Valuation Date.  Unless otherwise
determined by the Committee, in its sole discretion, subject to adjustment as
provided in Section IV(b), the Initial Value of any Incentive Unit granted under this Plan shall be equal to the value
of such Incentive Unit determined as of the Valuation Date on which such
Incentive Unit is granted.  (b)          Recapitalization, Etc. In the event there is any change in the
outstanding common stock of the Corporation by reason of any merger,
reorganization, recapitalization, stock split, stock dividend, combination of
shares, increase or decrease in the number of outstanding shares or otherwise
(including that a sale of all or substantially all of the assets of its common
stock shall occur or be pending), there shall be substituted for, added to or
subtracted from each Incentive Unit then outstanding under the Plan, the number
of additional or partial Incentive Units that the Board determines accurately
reflects the effect of such merger, reorganization, recapitalization, stock
split, stock dividend, share combination or other such event.  Likewise, the Initial Value of each Incentive
Unit shall also be adjusted by the Board if it determines in its sole
discretion that such adjustment is appropriate. 
In the event that the Corporation enters into a transaction with an
Affiliate of the Corporation, the Board may make an equitable adjustment to the
Incentive Units if, in its sole discretion, the Board determines that such
adjustment is appropriate.  (c)Vesting in Incentive Units. The Incentive Units granted to an Employee shall
vest as determined by the Committee, in its sole discretion.  In the absence of any action by the Committee
to select a different vesting schedule, Incentive Units shall vest
cumulatively, in twenty percent (20%) increments annually and such vesting
shall end upon the Employees (i) Separation from Service for any reason
whatsoever or (ii) transfer from the employer to whom he was providing
services as of the date he received an Incentive Unit award to an Affiliate
(other than a Subsidiary). 
Notwithstanding the foregoing, to the extent not previously canceled or
forfeited, Incentive Units shall become immediately vested if, within twelve
(12) months after a Change in Control of the Corporation, an Employees
employment is terminated (x) by the Corporation or Affiliate for any
reason other than Good Cause, (y) as a result of death or permanent
disability, or (z) by the Employee for Good Reason.  Notwithstanding any Plan provision to the
contrary, if an Employee separates from service for Good Cause, all Incentive
Units shall be immediately forfeited on the date of the Employees Separation
from Service.  (d)          Exercise of Incentive Units; Fixed Payment Date.  (i)            Default

Gains shall be paid in a lump sum in the next fiscal quarter.  Notwithstanding the foregoing, with respect
to any exercise occurring in the last fiscal month of any fiscal year, related
Gains shall be paid  7


during the
first fifteen (15) days of the second fiscal quarter following the Default
Fixed Exercise Date.  (ii)Elected Fixed Exercise Date. 
Notwithstanding Section IV(d)(i), the Committee, in its sole
discretion, may permit an Employee to elect an Elected Fixed Exercise Date on
which Incentive Units shall be exercised. 
Gains resulting from such exercise shall be paid in a lump sum in the
next fiscal quarter.  Notwithstanding the
foregoing, with respect to any exercise occurring in the last fiscal month of
any fiscal year, related Gains shall be paid during the first fifteen (15) days
of the second fiscal quarter following the Elected Fixed Exercise Date.  An Elected Fixed Exercise Date must be on or
after the date an Incentive Unit vests and prior to the Default Fixed Exercise
Date.  (A)          Process
and Timing.  To select an Elected Fixed Exercise Date, the
Employee must complete and submit an Exercise and Payment Agreement to the
Corporation no later than the end of the calendar year prior to the year in
which an Incentive Unit is granted, or such earlier date specified by the Committee.  The Exercise and Payment Agreement shall
become irrevocable as of the end of such calendar year, or such earlier date as
specified by the Committee. 
Notwithstanding the foregoing, at the discretion of the Committee, an
Employee may select an Elected Fixed Exercise Date within thirty (30) days
after the Incentive Unit is granted, provided that the Exercise and Payment
Agreement is submitted at least twelve (12) months in advance of the Incentive
Units first vesting date.  In such case,
the Exercise and Payment Agreement shall become irrevocable as of the end of
such thirty (30) day period.  (B)Section 409A Transition Relief. 
Notwithstanding paragraph (A), on or before December 31, 2008, the
Committee, in its sole discretion, may permit Employees to select or change an
Elected Fixed Exercise Date for previously awarded Incentive Units by
submitting an Exercise and Payment Agreement to the Corporation consistent with
transition relief provided by the Department of the Treasury in
Notice 2006-79, Notice 2007-86 and proposed regulations promulgated under Section 409A.  If an Employee submits or changes an Exercise
and Payment Agreement pursuant to this paragraph (B), then the last Exercise
and Payment Agreement validly in effect as of December 31, 2008 shall
control and be irrevocable.  (iii)Separation from Service. 
Notwithstanding Sections IV(d)(i) and IV(d)(ii) and subject to
Section IV(d)(iv), a deemed exercise shall occur with respect to vested
Incentive Units on the date an Employee experiences a Separation from
Service.  Resulting Gains shall be paid
in a lump sum in the fiscal quarter following the Employees Separation from
Service.  Notwithstanding the foregoing,
with respect to any deemed exercise occurring in the last fiscal month of any
fiscal year, related Gains shall be paid during the first fifteen (15) days of
the second fiscal quarter following the Employees Separation from

Employees Separation from Service, (2) the Employees Elected Fixed
Exercise Date or (3) the Default Fixed Exercise Date.  Resulting Gains shall be paid in a lump sum
in the fiscal quarter following the deemed exercise date.  Notwithstanding the foregoing, with respect
to any deemed exercise occurring in the last fiscal month of any fiscal year,
related Gains shall be paid during the first fifteen (15) days of the second
fiscal quarter following the deemed exercise date.  (v)           Death.  In the
event of an Employees death, a deemed exercise shall occur with respect to
vested Incentive Units on the date of the Employees death.  Resulting Gains shall be paid to the Employees
Beneficiary in a lump sum in the first fiscal quarter following the Employees
death.  Notwithstanding the foregoing,
with respect to any deemed exercise occurring in the last fiscal month of any
fiscal year, related Gains shall be paid to the Employees Beneficiary during
the first fifteen (15) days of the second fiscal quarter following the Employees
death.  (vi)          Forfeiture of Unvested
Incentive Units.  Subject to Section IV(c),
in the event of an Employees Separation from Service, death or transfer to an
Affiliate (other than a Subsidiary), all unvested Incentive Units shall be
forfeited immediately on the date of such Separation from Service, death or
transfer.  (vii)         Transfer to an Affiliate
(other than a Subsidiary). 
Effective with respect to Incentive Units awarded on or after January 1,
2009, in the event that an Employee transfers from the employer to whom he was
providing services as of the date he received an Incentive Unit Award to an
Affiliate (other than a Subsidiary), a deemed exercise shall occur with respect
to vested Incentive Units on the Employees transfer date.  Resulting Gains (including any earnings or
losses, as described below) shall be paid in a lump sum at the earliest time
payment would otherwise have occurred, applying the provisions of Sections
IV(d)(i)-(v).  Until such time as the
Gains are paid, the Committee, in its sole discretion, may permit an Employee
to notionally invest such Gains in accordance with Section IV(f).  (e)Value of Incentive Unit Upon Exercise.  Upon the
exercise or deemed exercise of an Incentive Unit, the Employee (or his
Beneficiary in the event of the Employees death) shall receive from the
Corporation a cash payment equal to the Gain.  (i)Final Value Generally.  For purposes
of calculating the Gain, the Final Value shall equal the Incentive Unit Value as of the Valuation Date immediately preceding the
exercise date or, if applicable, the Value on the Valuation Date  9


coinciding
with the date of such exercise; provided that if the date of such exercise or
deemed exercise is within thirty (30) days of the end of the Corporations
fiscal quarter, then the Final Value shall equal the Incentive Unit Value as
of the Valuation Date immediately following the date of such exercise or deemed
exercise.  (ii)           Final
Value for Employees Transferred to An Affiliate. 
Notwithstanding any provision to the contrary, for purposes of
calculating the Gain in relation to the deemed exercise of Incentive Units
pursuant to Section IV(d)(vii), the Final Value shall equal the
Incentive Unit Value as of the Valuation
Date immediately preceding the Employees transfer date or, if applicable, the
Value on the Valuation Date coinciding with the Employees transfer date;
provided that if the date of such transfer is within thirty (30) days of the
end of the Corporations fiscal quarter, then the Final Value shall equal the
Incentive Unit Value as of the Valuation Date immediately following the Employees
transfer date.  (iii)          Final Value Upon Certain
Terminations Following a Change in Control.Notwithstanding Section IV(e)(i), in the event an
Employee experiences an involuntary termination of employment other than for

months following a Change in Control, for
purposes of calculating the Gain resulting from a deemed exercise, the Final
Value shall equal the Value of the Incentive Unit as of the fiscal month ended
immediately preceding the Change in Control, provided that, notwithstanding the
foregoing, in determining such Final Value, the Corporation shall exclude any
non-cash charges incurred in connection with the Change in Control which would
otherwise have been included in such calculation.  (f)Investment of Transferred Employees Gains.  Upon the
deemed exercise of an Employees Incentive Unit pursuant to Section IV(d)(vii),
the Committee, in its sole discretion, may permit the Employee to make a
written election to notionally invest his Gain in investment funds selected by
the Committee.  The Committee may
promulgate rules and procedures governing investment elections under this Section IV(f).  If such an
election is made, the Committee shall establish a bookkeeping account for the
Employee to reflect earnings and losses allocable thereto at such times
and in such manner as shall be determined by the Committee.  Notwithstanding any provision in the Plan to
the contrary, earnings and losses based on an Employees investment elections
shall begin to accrue only as of the date such Employees Gain is credited to
his account.  (g)Expiration Date.  Outstanding Incentive Units
shall expire at 5:00 p.m. New York City time on the sixth (6th) anniversary of the grant date.  (h)Deferral Election.  Employees eligible to
participate in the Deferred Compensation Plan may elect to contribute up to
100% of the Gain, if any, into the Deferred Compensation Plan on a pre-tax
basis.  To make a deferral election, the
Employee must complete and submit a Deferral Agreement to the Corporation no
later than the end of the calendar year prior to the year in which an Incentive
Unit is granted, or such earlier date specified by the  10


Committee.  The Deferral Agreement shall become irrevocable as of the end of such
calendar year, or such earlier date as specified by the Committee.  Notwithstanding the foregoing, at the
discretion of the Committee, an Employee may complete and submit a Deferral Agreement
within thirty (30) days after the date the Incentive Unit is granted, provided
that the Deferral Agreement is submitted at least twelve (12) months in advance
of the Incentive Units first vesting date. 
In such case, the Deferral Agreement shall
become irrevocable as of the end of such thirty (30) day period.  V.  BENEFICIARY DESIGNATION  (a)          Beneficiary.  Each
Employee may, at any time, designate one or more Beneficiaries (both primary as
well as contingent) to receive any benefits payable under the Plan upon his
death.  The Beneficiary designated under
this Plan may be the same or different from the Beneficiary designation under
any other plan of the Corporation or Subsidiary in which the Employee
participates.  (b)          Beneficiary Designation; Change.  An Employee shall designate his
Beneficiary by completing and signing a beneficiary designation form
established by the Committee or its delegate, and returning it to the Committee
or its designated agent.  An Employee may
change his Beneficiary designation by completing, signing and otherwise
complying with the terms of the beneficiary designation form and the Committees
rules and procedures, as in effect from time to time.  Upon the acceptance by the Committee of a new
beneficiary designation form, all Beneficiary designations previously filed
shall be canceled.  The Committee shall
rely on the last completed beneficiary designation form filed by the Employee
and accepted by the Committee before his death.  (c)Acknowledgment.  No Beneficiary designation
or change in Beneficiary designation shall be effective until accepted by the
Committee or a Plan representative.  (d)          No Beneficiary Designation.  If
an Employee fails to designate a Beneficiary as provided in this Section V
or, if all designated Beneficiaries predecease the Employee, then the Employees
designated Beneficiary shall be deemed to be his surviving spouse.  If the Employee leaves no surviving spouse,
payment shall be made to the Employees estate.  (e)Discharge of Obligations.  The
complete payment under the Plan to a Beneficiary shall fully and completely
discharge the Corporation and its Subsidiaries from all further obligations
under this Plan with respect to the Employee.  VI.  MISCELLANEOUS PROVISIONS  (a)          Assignment or Transfer. No right to any accrued but unpaid Incentive Unit
shall be sold, assigned, redeemed, pledged, transferred or otherwise encumbered
by an Employee except by will or the laws of descent and distribution.  (b)          Withholding Taxes. The Corporation or the appropriate Subsidiary
shall have the right to deduct from all cash payments hereunder any federal,
state, local or foreign income and employment taxes required by law to be
withheld with respect to such payments.  11


(c)Costs and Expenses. The costs and expenses of administering the Plan
shall be borne by the Corporation and shall not be charged against any
particular award nor to any Employee receiving an Incentive Unit but shall be
included in the Corporations computation of consolidated net income or loss.  (d)          Funding of Plan. The Plan shall be unfunded. The Corporation shall
not be required to segregate any of its assets to assure the payment of any
Incentive Unit under the Plan. Neither the Employees nor any other persons
shall have any interest in any fund or in any specific asset or assets of the
Corporation or any other entity by reason of any accrued but unpaid Incentive
Unit. The interests of each Employee hereunder are unsecured and shall be
subject to the general creditors of the Corporation and the applicable
Subsidiaries.  (e)Other Incentive Plans. The adoption of the Plan does not preclude the
adoption by appropriate means of any other incentive plan for Employees of the
Corporation or any Subsidiary.  (f)Plurals and Gender. Where appearing in this Plan, masculine gender
shall include the feminine and neuter genders, and the singular shall include
the plural, and vice versa, unless the context clearly indicates a different
meaning.  (g)          Headings. The headings and sub-headings in this Plan are
inserted for the convenience of reference only and are to be ignored in any
construction of the provisions hereof.  (h)          Severability. In case any provision of this Plan shall be held
illegal or void, such illegality or invalidity shall not affect the remaining
provisions of this Plan, but shall be fully severable, and the Plan shall be
construed and enforced as if said illegal or invalid provisions had never been
inserted herein.  (i)           Limitations on Liability. Neither the Corporation nor any Subsidiary shall
be responsible in any way for any action or omission of the Board, the
Committee, or any other fiduciaries in the performance of their duties and
obligations as set forth in this Plan. Furthermore, neither the Corporation nor
any Subsidiary shall be responsible for any act or omission of any of their
agents, or with respect to reliance upon advice of their counsel, provided that
the Corporation and/or the appropriate Subsidiary relied in good faith upon the
action of such agent or the advice of such counsel. Neither the Corporation,
any Subsidiary, the Board, the Committee, nor any agents, employees, officers,
directors or stockholders of any of them, nor any other person, shall have any
liability or responsibility with respect to this Plan, except as expressly
provided herein.  (j)Incapacity. If the Committee shall receive evidence satisfactory to it that a
person entitled to receive payment of, or exercise, any Incentive Unit is, at
the time when such benefit becomes payable, a minor, or is physically or
mentally incompetent to receive such Incentive Unit and to give a valid release
thereof, and that another person or an institution is then maintaining or has
custody of such person and that no guardian, committee or other representative
of the estate of such person shall have been duly appointed, the Committee may
make payment of such Incentive Unit otherwise payable to  12


such person to such other person or institution, including a custodian
under a Uniform Gifts to Minors Act, or corresponding legislation (who shall be
an adult, a guardian of the minor or a trust company), and the release by such
other person or institution shall be a valid and complete discharge for the
payment or exercise of such Incentive Unit.  (k)          Cooperation of Parties. All parties to this Plan and any person claiming
any interest hereunder agree to perform any and all acts and execute any and
all documents and papers which are necessary or desirable for carrying out this
Plan or any of its provisions.  (l)           Governing Law. All questions pertaining to the validity,
construction and administration of the Plan shall be determined in accordance
with the laws of the State of New Jersey, without giving effect to conflict of
law principles.  (m)Nonguarantee of Employment. Nothing contained in this Plan shall be construed
as a contract of employment between the Corporation or any Subsidiary and any
Employee, as a right of any Employee to be continued in the employment of the
Corporation or any Subsidiary, or as a limitation on the right of the
Corporation or any Subsidiary to discharge any of its Employees, at any time,
with or without cause.  (n)          Notices. Each notice relating to this Plan shall be in writing
and delivered in person, by recognized overnight courier or by certified mail
to the proper address. Except as otherwise provided in any Incentive Unit award
agreement with respect to the exercise thereunder, all notices to the
Corporation or the Committee shall be addressed to it at GAF-Elk Corporation,
14911 Quorum Drive, Suite 600, Dallas, TX 75254, Attn: Senior Vice
