                                    EXHIBIT A

                         AGREEMENT TO ARBITRATE DISPUTES

I recognize that certain events may ultimately lead to my leaving GAF Materials
Corporation, ElkCorp and/or its and their respective subsidiaries or affiliates
(collectively the "Company") and, at that time, disputes may arise between the
Company and me relating to my hiring, employment or separation of employment by
the Company or events occurring thereafter relating to my employment. I
understand and agree that by entering into this Agreement to Arbitrate Disputes
("Agreement"), I anticipate gaining the benefits of a speedy, simple, and
impartial dispute resolution procedure. The mutual promises by the Company and
me to arbitrate, rather than to litigate claims, and my employment or continued
employment by the Company pursuant to the August 2007 Employment Agreement are
consideration for this Agreement.

CLAIMS COVERED BY THIS AGREEMENT
--------------------------------

The Company and I mutually agree to the resolution, by final and binding
arbitration, of all claims relating to my employment by the Company that the
Company may have against me, or that I may have against the Company and/or its
shareholders, officers, directors, employees or agents, following the
termination of my employment. Such claims include, without limitation, claims
for wages or salary, severance or other compensation; claims for breach of any
contract or covenant (express or implied); claims for violation of any
whistle-blower protections, claims under New Jersey's Conscientious Employee
Protection Act ("CEPA"); tort claims; claims for any type of discrimination
(race, gender, sexual harassment, sexual orientation, religion, national origin,
age, marital status, or medical condition, handicap or disability); claims for
benefits (except where any employee benefit or pension plan specifies a
different procedure for resolving claims); and claims for violation of any
federal statute (Age Discrimination in Employment Act, the Americans with
Disabilities Act, Civil Rights Act of 1964, Civil Rights Act of 1991, Employee
Retirement Income Security Act of 1974, Family Medical Leave Act of 1993, Older
Worker Benefit Protection Act, Pregnancy Discrimination Act of 1978)), state, or
other governmental law, statute, regulation, or ordinance, claims under New
Jersey's Law Against Discrimination, Texas' Labor Code and/or the Texas Human
Rights Act (collectively referred to as "Claims"); but excluding claims for
worker's compensation, unemployment benefits, claims which are filed with any
state and/or federal agencies, or lawsuits seeking requests for injunctive or
equitable relief in connection with the enforcement of any agreements between
the Company and me which seek to prohibit me from disclosing the Company's
confidential or proprietary information and/or prohibit me from competing with
the Company or to compel arbitration of the Claims.

ARBITRATION PROCEDURES
----------------------

Written notice of any Claims must be given no later than the applicable statute
of limitations for the cause of action alleged. Written notice to the Company
shall be sent to the Company's General Counsel in Wayne, New Jersey. Written
notice to the Employee shall be sent to his last known address.



                                       8
<PAGE>



The Company and I agree that any arbitration shall be in accordance with the
National Rules for the Resolution of Employment Disputes of the American
Arbitration Association ("AAA") in effect at the time of the hearing (a current
copy of those rules is available through the Law Department). The arbitration
shall be before one neutral arbitrator selected from the Regional Employment
Dispute Resolution Roster. The arbitration shall take place in the city nearest
to my last place of employment with the Company.

All fees and expenses of the arbitrator shall be borne by the Company. The
arbitrator shall determine my rights and obligations and those of the Company
according to the applicable substantive laws. Notwithstanding the foregoing, in
rendering the award, the arbitrator will have no authority to award punitive
damages in excess of Twenty-Five Thousand ($25,000) Dollars unless such a
limitation is prohibited by applicable law. The Company and I shall each bear
the expenses of our own counsel, experts, witnesses, preparation, and
presentation of proofs, unless otherwise awarded by the arbitrator; however, any
such award shall not exceed Twenty-Five Thousand ($25,000) Dollars unless such a
limitation is prohibited by applicable law. Judgment on the award rendered in
arbitration may be entered in any court having jurisdiction.

KNOWING AND VOLUNTARY WAIVER OF RIGHTS
--------------------------------------

BY SIGNING THIS AGREEMENT, I UNDERSTAND THAT CERTAIN EVENTS MAY LEAD TO MY

                                    EXHIBIT B

               AGREEMENT REGARDING CONFIDENTIALITY AND COMPETITION

         In consideration of my employment pursuant to the August 2007
Employment Agreement and my access to and receipt of Confidential Information as
described below, or such other good and valuable consideration by GAF Materials
Corporation, ElkCorp, GAF-ELK Corporation and its and their respective
subsidiaries and affiliates (collectively "GAFMC"), I agree to the terms and
conditions in this Agreement.

         1. Confidential Information. I will not, without GAFMC's prior written
permission, directly or indirectly utilize for any purpose other than
performance of my employment duties to GAFMC, or disclose to anyone outside of
GAFMC, either during or after my employment with GAFMC, any information provided
to or obtained by me in the course of my employment with GAFMC, trade secrets or
other confidential information of GAFMC, or any information received by GAFMC in
confidence from or about third parties, as long as such matters remain trade
secrets or confidential. Trade secrets and other confidential information shall
include any information or material which is not generally known to the public,
and which (a) is generated or collected by or utilized in the operations of
GAFMC and relates to the actual or anticipated business or research or
development of GAFMC or GAFMC's actual or prospective vendors, customers or
clients; or (b) is suggested by or results from any task assigned to me by GAFMC
or work performed by me for or on behalf of GAFMC or any customer or client of
GAFMC. Confidential information shall not be considered generally known to the
public if revealed improperly to the public by me or others without GAFMC's
express written consent and/or in violation of an obligation of confidentiality
to GAFMC. Examples of confidential information include, but are not limited to,
customer and supplier identification and contacts, business relationships,
contract provisions, pricing, margins, business plans, marketing plans,
financial data, business and customer strategies, techniques, technical
know-how, formulae, research, development, technological and production
information, processes, designs, architecture, prototypes, models, software,
solutions, discussion guides, personal or performance information about
employees, research and development, patent applications and plans or proposals
related to the foregoing. The confidentiality obligations herein shall not
prohibit me from divulging confidential information or trade secrets by order of
court or agency of competent jurisdiction or as required by law; however, I
shall promptly inform GAFMC of any such situations and shall take reasonable
steps to prevent disclosure of confidential information or trade secrets until
GAFMC has been informed of such required disclosure and has had a reasonable
opportunity to seek a protective order.

         2. Non-Competition. GAFMC does not intend to interfere with any former
employee's employment opportunities unless there is a conflict with GAFMC's
legitimate business interests. In order to help protect those interests, during
the Term of Employment set forth in the Employment Agreement by and between me
and GAFMC and for twenty-four (24) months (the "Restricted Period") after the
expiration of such Term of Employment, I agree not to become engaged, directly
or indirectly, as an employee, consultant, or otherwise for any Competitive
Organization in any management, executive, sales and marketing, research and
development or operations position. I may accept such an engagement with a
Competitive Organization if: (i) it is diversified and has well-established,
pre-existing, separate and distinct divisions, (ii) I am involved only in that


                                       11
<PAGE>



part of the business which is not a Competitive Organization, and (iii) prior to
my accepting such an engagement, in any capacity, the Competitive Organization
provides GAFMC with written assurances, satisfactory to GAFMC, that I will not,
and the Competitive Organization will not cause me to, render services directly
or indirectly in connection with any Competitive Product. The running of the
Restricted Period shall be stopped or tolled for any period of time following
the termination of my GAFMC employment during which I compete with GAFMC in
violation of this paragraph 2.

          (ii) "Competitive Product" means: any product(s) or service(s) offered
by GAFMC at the time my employment relationship terminates or with which I had
substantial involvement at any time during the twenty-four (24) months
immediately preceding my last day of employment by GAFMC; and

         (iii)"Competitive Organization" means: any person(s),
organization(s),or entity(ies)which is/are a distributor, manufacturer or
formulator of a Competitive Product.

         3. Conduct Regarding GAFMC Employees. For twelve (12) months after
termination, I will not, directly or indirectly, attempt to hire, engage the
services of, or employ in any manner any person who is then an GAFMC executive,
management, sales and marketing, operations, engineering, or research and
development employee.

         4. Assignment of Developments. I hereby assign to GAFMC my entire
right, title and interest in any idea, formula, invention, discovery, design,
drawing, process, method, technique, device, improvement, computer program and
related documentation, technical and non-technical data, work of authorship and
patent and patent applications (all hereinafter called "Developments"), which I
may solely or jointly conceive, write or acquire in whole or in part during the
period I am employed by GAFMC, and for six (6) months thereafter, which relate
in any way to the actual or anticipated business or technology or research or
development of GAFMC for which I had access or responsibility during my
employment at GAFMC, or which are suggested by or result from any task assigned
to me or work performed by me for or on behalf of GAFMC, whether or not such
Developments are made, conceived, written or acquired during normal hours of
work or using GAFMC's facilities, and whether or not such Developments are
patentable, copyrightable or susceptible to other forms of protection. This
assignment does not apply to any Development for which no equipment, supplies,
facilities or trade secret, proprietary or confidential information of GAF was
used, and which was developed entirely on my own time unless (a) the development
relates (i) to the actual or anticipated business of GAFMC, for which I had
access or responsibility during my employment at GAFMC, or (ii) to GAFMC's
actual or demonstrably anticipated research or development, for which I had
access or responsibility during my employment at GAFMC or (b) the Development
results from any work performed by me for GAFMC. I agree all rights in any
Developments created during my employment at GAFMC belong to GAFMC.

         5. Remedies. Any breach or threatened breach of this Agreement will
irreparably injure GAFMC, and money damages will not be an adequate remedy.
Accordingly, GAFMC may obtain and enforce an injunction prohibiting me from
violating or threatening to violate this Agreement. This is not GAFMC's only
remedy, it is in addition to any other remedy available.



                                       12

         6. Choice of Law and Forum: Submission to Jurisdiction. The
construction, interpretation and performance of this Agreement shall be governed
by, and in accordance with, the laws of the State of New Jersey, and any action
or proceeding arising from or related to this Agreement shall be commenced,
prosecuted and maintained only in the State of New Jersey. I hereby consent to
the personal jurisdiction of the state and federal courts located in New Jersey
with respect to all actions and proceedings of the type described in the
immediately preceding sentence.

         7. Advice. I have the right to consult an attorney before signing this
Agreement.

         8. General. Each of the provisions of this Agreement shall be binding
on me after my employment terminates, regardless of the reason(s) for
termination.

         This Agreement supersedes all prior agreements dealing with any of the
subject matter of this Agreement and can be revoked or modified only by a
written agreement signed by me and GAFMC.

         The provisions of this agreement are severable, and the invalidity or
unenforceability of any provision shall not affect application of any other
provision. When possible, consistent with the purpose of this Agreement, any
invalid provision of this Agreement may be reformed, and as reformed, enforced.

         GAFMC may assign its rights under this Agreement.
