                                                                 EXHIBIT 10.16.2

                                 FIRST AMENDMENT

                                     TO THE

                           RANGE RESOURCES CORPORATION
                             1999 STOCK OPTION PLAN

     THIS AMENDMENT (the "AMENDMENT") to the Amended and Restated 1999 Stock
Option Plan, dated April 5, 2001 (the "PLAN"), was duly approved and adopted by
the shareholders of Range Resources Corporation (the "CORPORATION") on May 24,
2001.

     1. Article V(a) of the Plan shall be amended and restated in its entirety
as follows:

        (a) STOCK GRANT AND AWARD LIMITS. The Committee may from time to time
grant Awards to one or more employees, Consultants or Directors determined by it
to be eligible for participation in the Plan in accordance with the provisions
of Paragraph VI. Subject to adjustment in the same manner as provided in
Paragraph IX with respect to shares of Stock subject to Awards then outstanding,
the aggregate number of shares of Stock that may be issued under the Plan shall
not exceed 3,400,000 shares. Shares shall be deemed to have been issued under
the Plan only (i) to the extent actually issued and delivered pursuant to an
Award, or (ii) to the extent an Award is settled in cash. To the extent that an
Award lapses or the rights of its Holder terminate, any shares of Stock subject
to such Award shall again be available for the grant of an Award.
Notwithstanding any provision in the Plan to the contrary, the maximum number of
shares of Stock that may be subject to the Awards granted to any one individual
during any calendar year may not exceed 250,000 shares of Stock (subject to
adjustment in the same manner as provided in Paragraph IX with respect to shares
of Stock subject to Awards then outstanding). The limitation set forth in the
preceding sentence shall be applied in a manner which will permit compensation
generated under the Plan to constitute "performance-based" compensation for
purposes of section 162(m) of the Code including, without limitation, counting
against such maximum number of shares, to the extent required under section
162(m) of the Code and applicable interpretive authority thereunder, any shares
subject to Awards that are canceled or repriced.<PAGE>

                 AMENDMENT TO ASSOCIATED MATERIALS INCORPORATED
                          EMPLOYEE STOCK PURCHASE PLAN

         At a meeting held on December 27, 2001, the Board of Directors of
Associated Materials Incorporated took action to amend and restate in its
entirety Section X.B of the Associated Materials Incorporated Employee Stock
Purchase Plan to read as follows:

                  B. The Plan may be terminated or suspended at any time by
         action of the Board; provided, however, that the termination or
         suspension of the Plan shall not adversely affect the terms of any
         outstanding purchase rights. The Plan may be suspended by action of the
         Board for one or more Purchase Periods (or any portion of a Purchase
         Period) and until such time as the Board determines to reinstate the
         Plan. Any suspension of the Plan will be subject to such terms and
         conditions as the Board determines in its sole discretion; provided,
         however, that such terms and conditions shall apply in the same manner
         to all Eligible Employees.<PAGE>
                                                                   EXHIBIT 10.12

                         AMENDED AND RESTATED AGREEMENT

         THIS AMENDED AND RESTATED AGREEMENT (this "Agreement"), made and
entered into this 5th day of February 2002, by and between Associated Materials
Incorporated, a Delaware corporation ("AMI"), and MICHAEL CAPORALE, JR.
("CAPORALE").

                                  WITNESSETH:

         WHEREAS, AMI and CAPORALE are parties to an Agreement, dated December
18, 1999 (the "Prior Agreement"), setting forth the terms and conditions of
CAPORALE's employment with AMI; and

         WHEREAS, AMI and CAPORALE each desire to amend and restate in its
entirety the Prior Agreement as set forth in this Agreement;

         NOW, THEREFORE, in consideration of the mutual covenants and
obligations contained herein, AMI hereby agrees to continue to employ CAPORALE
and CAPORALE hereby agrees to continue to be employed by AMI upon the terms and
conditions hereinafter set forth.

1. Employment. AMI agrees to employ CAPORALE and CAPORALE agrees to be employed
by AMI as President and Chief Executive Officer of Alside, a division of AMI
("Alside"). CAPORALE's duties and responsibilities shall be those traditionally
associated with the president and chief executive officer of a corporation.
CAPORALE shall not be required to report to anyone other than the President of
AMI or Board of Directors of AMI.

2. Compensation.

         (a) Base Salary. CAPORALE shall be paid a base salary of $475,000 per
annum to be reviewed annually by the Board of Directors of AMI. CAPORALE's
salary shall be subject to all appropriate federal and state withholding taxes
and shall be payable in accordance with the normal payroll procedures of AMI.

         (b) Bonus Payments. For calendar year 2002 and for each calendar year
thereafter during the term of this Agreement, CAPORALE shall be paid a cash
bonus equal to 0.0079 times Alside's earnings before income taxes and after
interest expense allocated to Alside, as determined by AMI consistent with AMI's
past practice. On or prior to December 31 of each calendar year, AMI will pay
CAPORALE an amount equal to 90% of CAPORALE's estimated bonus, as reasonably
determined by AMI and consistent with this Section 2(b). The final bonus amount
will be determined, and any supplemental payment (or reimbursement of any over
payment) will be made at such times as other bonuses are paid to Alside's
executives.

<PAGE>

3. Benefits.

         (a) Benefit Plans. CAPORALE shall participate in all benefit programs
and plans provided to other Alside executives in accordance with the terms and
conditions of those programs and plans. Such benefits currently include medical,
dental, short and long-term disability and group life insurance, an employee
spending account, employee stock purchase plan, and the Alside 401(k) Plan.
CAPORALE's group life insurance benefit shall be two times his base salary and
cash bonus for the preceding calendar year, adjusted annually on or before March
31st of each year; provided, however, that the amount of CAPORALE's group life
insurance benefit shall not exceed the maximum life insurance benefit permitted
for any individual under Alside's then-current group life insurance plan.

         (b) Car Allowance. CAPORALE shall be paid a car allowance as provided
to other executives of Alside. Currently the car allowance is $1,000 per month.
Such allowance shall be paid by AMI to CAPORALE on the last business day of each
month or on such other day during the month as these payments are made to other
executives of Alside.

         (c) Club Membership. AMI shall reimburse CAPORALE for monthly dues and
business related expenses in connection with his country club membership
throughout the term of this Agreement.

4. Vacations. CAPORALE shall be permitted to take vacation time in each calendar
year as determined by the Board of Directors of AMI. CAPORALE shall be entitled
to four weeks paid vacation during each calendar year. In addition, CAPORALE
shall be entitled to such holidays as may be established by Alside for employees
generally and a reasonable number of personal and sick days not inconsistent
with the performance of his duties hereunder.

5. Term of Employment. This Agreement shall be effective when executed by both
CAPORALE and AMI and shall expire on the close of business on December 31, 2004;
provided, however, that commencing on January 1, 2005 and each January 1
thereafter, the term of this Agreement shall automatically be extended for one
additional year unless, not later than September 30 of the immediately preceding
year, either AMI or CAPORALE shall have given written notice that it or he, as
the case may be, does not desire to have the term of this Agreement extended.

6. Termination. The employment relationship between AMI and CAPORALE created
hereunder shall terminate before the expiration of the term of this Agreement
upon the occurrence of any one of the following events:

         (a) Mutual Agreement. Upon mutual written agreement between CAPORALE
and AMI. Any severance hereunder shall be payable as mutually agreed.

         (b) Death. Upon CAPORALE's death, AMI shall have no further obligations
hereunder other than for amounts accrued and unpaid prior to the date of his
death.

         (c) Termination by AMI for Cause. AMI may terminate this Agreement for
Cause (as defined below). If CAPORALE's employment is terminated for Cause by
AMI pursuant to this Section 6(c), AMI shall have no further obligations
hereunder other than for amounts

                                      -2-
<PAGE>

accrued and unpaid prior to the date of termination for Cause. As used herein,
"Cause" for termination by AMI shall mean that CAPORALE shall have (i) been
convicted of a criminal violation involving fraud, embezzlement or theft; (ii)
committed intentional wrongful damage to property of AMI or any subsidiary of
AMI; or (iii) committed intentional wrongful disclosure of confidential
information of AMI or any subsidiary of AMI, and any such act shall have been
materially harmful to AMI. For purposes of this Agreement, no act or failure to
act on the part of CAPORALE shall be deemed "intentional" if it was due
primarily to an error in judgment or negligence, but shall be deemed
"intentional" only if done or omitted to be done by CAPORALE not in good faith
and without reasonable belief that CAPORALE's action or omission was in the best
interest of AMI. Nothing herein will limit the right of CAPORALE or his
beneficiaries to contest the validity of any determination by CAPORALE to
terminate CAPORALE for Cause.

         (d) Termination by AMI Without Cause. AMI may terminate this Agreement
at any time with or without Cause.

         (e) Termination by CAPORALE. CAPORALE may terminate this Agreement at
any time with or without Good Reason (as defined).

         (f) Termination by CAPORALE for Good Reason. CAPORALE may terminate
this Agreement and become entitled to the rights set forth in Section 6(g)
hereof, if CAPORALE has Good Reason to terminate his employment with AMI. As
used herein, "Good Reason" to terminate employment with AMI occurs if: (1)
without his consent, duties are assigned to CAPORALE that are materially
inconsistent with his current duties or with his position as President and Chief
Executive Officer of Alside; (2) without his consent, duties and
responsibilities previously performed by CAPORALE are substantially reduced or
assigned to others; or (3) AMI breaches any of its material obligations under
this Agreement, including without limitation payment obligations and obligations
to provide benefits and, in each case specified in clauses (1), (2) and (3) of
this Section 6(f), AMI fails to cure any such alleged breach within 30 days
after AMI receives written notice of such alleged breach from CAPORALE.

         (g) Severance Payments. In the event CAPORALE's employment has been
terminated (x) by AMI without Cause, (y) by CAPORALE for Good Reason or (z) as a
result of AMI giving CAPORALE written notice that it does not desire to have the
term of this Agreement extended pursuant to Section 5 hereof, CAPORALE shall
receive the following:

                  (i)      An amount equal to three times CAPORALE's
                           then-current base salary;

                  (ii)     An amount equal to three times CAPORALE's annual cash
                           incentive payment (determined by reference to the
                           highest cash incentive payment received by CAPORALE
                           for services rendered in any calendar year during the
                           three full calendar years immediately prior to the
                           termination of his employment).

                  (iii)    If CAPORALE's employment is terminated after June 30
                           of any calendar year, an additional payment in an
                           amount equal to the cash bonus (calculated in
                           accordance with Section 2(b) hereof) based upon
                           Alside's earnings for the then-current calendar year
                           from January 1 through the end

                                      -3-
<PAGE>

                           of the last full calendar month immediately prior to
                           the effective date of his termination of employment
                           and budgeted Alside earnings for the remaining full
                           calendar months of that calendar year. The actual
                           bonus payment will be prorated on the actual number
                           of days CAPORALE was employed by AMI during the
                           calendar year in which his employment with AMI was
                           terminated.

                  (iv)     For a period of three years following the effective
                           date of the termination of his employment with AMI,
                           AMI will provide or arrange to provide CAPORALE with
                           the benefits he was receiving pursuant to Section 3
                           hereof on the effective date of the termination of
                           his employment (other than stock options, stock
                           purchase or similar stock-based benefits).
                           Notwithstanding the foregoing, benefits otherwise
                           receivable by CAPORALE pursuant to this Section
                           6(g)(iv) will be reduced to the extent comparable
                           benefits are actually received by CAPORALE from
                           another employer during the three-year period
                           following CAPORALE's termination of employment, and
                           any such benefits actually received by CAPORALE shall
                           be reported by CAPORALE to AMI.

                  (v)      The options to purchase 100,000 shares of AMI's
                           common stock granted to CAPORALE in 2000 under
                           Section 2(d) of the Prior Agreement (the "Options")
                           shall become fully and immediately vested and the
                           Options shall remain exercisable for 10 years from
                           the grant date, as provided in the agreement under
                           which the Options were granted.

7. Limitation on Payments and Benefits. Notwithstanding any provision of this
Agreement to the contrary, if any amount or benefit to be paid or provided to
CAPORALE under this Agreement (or any other agreement to which CAPORALE is a
party, including any stock option agreement) would be an "Excess Parachute
Payment," within the meaning of Section 280G of the Internal Revenue Code of
1986, as amended (the "Code"), or any successor provision thereto, but for the
application of this sentence, then the payments and benefits to be paid or
provided under this Agreement shall be reduced to the minimum extent necessary
(but in no event to less than zero) so that no portion of any such payment or
benefit, as so reduced, constitutes an Excess Parachute Payment. The
determination of whether any reduction in such payments or benefits to be
provided under this Agreement or otherwise is required pursuant to the preceding
sentence shall be made at the expense of AMI, if requested by the CAPORALE or
AMI, by a firm of independent accountants or a law firm selected by AMI and
reasonably acceptable to CAPORALE. The fact that CAPORALE's right to payments or
benefits may be reduced by reason of the limitations contained in this Section 7
shall not of itself limit or otherwise affect any other rights of CAPORALE other
than pursuant to this Agreement. In the event that any payment or benefit
intended to be provided under this Agreement or otherwise is required to be
reduced pursuant to this Section 7, CAPORALE shall be entitled to designate the
payments and/or benefits to be so reduced in order to give effect to this
Section 7. AMI shall provide CAPORALE with all information reasonably requested
by CAPORALE to permit CAPORALE to make such designation. In the event that
CAPORALE fails to make such designation within 10 business days of the date of
his termination of employment, AMI may effect such reduction in any manner it
deems appropriate.

                                      -4-
<PAGE>

8. Trade Secrets. CAPORALE recognizes and acknowledges that during his term of
employment hereunder, he will come into possession of trade secrets, customer
lists, and other confidential information in connection with the business of AMI
and Alside. CAPORALE agrees that he will not at any time disclose to any other
third party any trade secrets, business policies or other confidential
information pertaining to AMI's or Alside's business.

9. Legal Fees and Expenses.

         (a) It is the intent of AMI that CAPORALE not be required to incur
legal fees and the related expenses associated with the interpretation,
enforcement or defense of CAPORALE's rights under this Agreement by litigation
or otherwise because the cost and expense thereof would substantially detract
from the benefits intended to be extended to CAPORALE under this Agreement.
Accordingly, if it should appear to CAPORALE that AMI has failed to comply with
any of its obligations under this Agreement or in the event that AMI or any
other person takes or threatens to take any action to declare this Agreement
void or unenforceable, or institutes any litigation or other action or
proceeding designed to deny, or to recover from, CAPORALE the benefits provided
or intended to be provided to CAPORALE hereunder, AMI irrevocably authorizes
CAPORALE from time to time to retain counsel of CAPORALE's choice, at the
expense of AMI as hereafter provided, to advise and represent CAPORALE in
connection with any such interpretation, enforcement or defense, including
without limitation the initiation or defense of any litigation or other legal
action, whether by or against AMI or any director, officer, stockholder or other
person affiliated with AMI, in any jurisdiction. Without respect to whether
CAPORALE prevails, in whole or in part, in connection with any of the foregoing,
AMI will pay and be solely financially responsible for any and all attorneys'
and related fees and expenses incurred by CAPORALE in connection with any of the
foregoing; provided that, in regard to such matters, CAPORALE has not acted in
bad faith or with no colorable claim of success. The fees and expenses of
counsel solicited from time to time by CAPORALE shall be paid, or reimbursed to
CAPORALE if paid, as promptly as practicable (and in any event within 15
calendar days) upon presentation of a statement or statements prepared by such
counsel in accordance with its customary practices.

         (b) Notwithstanding anything contained in this Agreement to the
contrary, the provisions of Section 9(a) shall not be operative unless and until
a Change in Control (as defined herein) occurs. Upon the occurrence of a Change
in Control, the provisions of Section 9(a) shall become immediately operative
without further action.

10. Certain Defined Terms. In addition to terms defined elsewhere herein, the
following terms have the following meanings when used in this Agreement with
initial capital letters:

         (a) "Change in Control" means any transaction or series of
transactions, the result of which causes any person (as the term "person" is

Winspear Family, to become the beneficial owner (as the term "beneficial owner"
is defined in Rule 13d-3 or any successor rule or regulation promulgated under
the Securities Exchange Act) of securities representing more than 50% of the
combined voting power of the then-outstanding Voting Stock of AMI. For the
purpose of this Agreement, any

                                      -5-

Person (including any member of the Winspear Family) shall be deemed to
beneficially own shares of Voting Stock of AMI held directly or indirectly in
accordance with Rule 13d-3.

         (b) "Voting Stock" means securities entitled to vote generally in an
election of directors.

         (c) "Winspear Family" means William W. Winspear, his affiliates

Exchange Act), any trust established for the benefit of William W. Winspear or
members of his immediate family and any private charitable foundation controlled
by William W. Winspear or members of his immediate family.

CAPORALE and their respective heirs, executors, administrators or successors in
