                                 Exhibit 10.16
                  Amendment to Executive Employment Agreement

     This Amendment to Executive Employee Agreement ("Amendment") is entered
into on this 30 day of November, 1999, by and between AMERICAN BUILDERS &
CONTRACTORS SUPPLY CO., INC. (the "Company") and ROBERT BARELTS ("Executive").

     WHEREAS, the Company and Executive entered into that certain Employment
Agreement dated November 30, 1998 (the "Agreement"); and

     NOW, THEREFORE, in consideration of the mutual covenants made herein, and
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the Company and Executive agree as follows:

1.   All capitalized terms used herein and not otherwise defined shall have the
same meaning as such term is given in the Agreement.

2.   Section 4(b) of the Agreement is hereby amended and restated in its
entirety as follows:

          (b)  Annual Bonus.  For each calendar year of the Term from 1999
               -------------
        through 2003, Executive shall receive a bonus equal to one percent
        (1.0%) of the Company's Net Profits over the Threshold, if any. As used
        herein, "Net Profits" means the pre-federal income tax profits of the
        Company for the calendar year in which the bonus calculation is made.
        "Threshold" means one percent (1%) of gross sales of the Company for the
        calendar year in which the bonus calculation is made. The bonus
        described in this paragraph 4(b) is referred to herein as the "Annual
        Bonus". The Annual Bonus, if any, shall be paid on April 30/th/ of the
        calendar year following the year for which the bonus is determined. A
        calculation example for 2000 follows:

               ABC Gross Sales (2000)        $1,320,000,000.00
               ABC Net Profits               $   26,400,000.00
               Threshold (1% gross sales)    $   13,200,000.00
               Net Profits Over Threshold    $   13,200,000.00

               Total annual Bonus:           $      132,000.00

          The foregoing example (including the dates and amounts referenced
        therein) are for illustrative purposes only and are not intended to
        represent any particular result. The Company makes no representation or
        warranty with respect to the income earned in the past or projected to
        be earned at any time, and the Company makes no representation or
        warranty that Executive will receive any amount of Annual Bonus. The
        calculations of Net Profits and any bonuses due hereunder shall be made
        in the reasonable discretion and in accordance with generally accepted
        accounting principles by the Company's Chief Financial Officer. From
        time to time, the Company may change its accounting principles and tax
        status as determined by its Board of Directors.

          In any event, Executive shall not be entitled to receive the Annual
        Bonus if the Company's Net Profits do not exceed the Threshold. The
        Company makes no representation or warranty with respect to the income
        earned in the past or projected to be earned at any time, and the
        Company makes no representation or warranty that Executive will receive
        any amount of Earning Bonus.

3.      All references in the agreement shall mean the Agreement as amended
        hereby.

4.      Except as set forth here, in the agreement is herby ratified and
        affirmed in all respects and remains in full force and effect.
