     WHEREAS,  Stockholder is the record and  beneficial  owner of the number of
shares of Common Stock,  par value $1.00 per share, of the Company (the "Company

     WHEREAS,  as a condition to their willingness to enter into the LOI and the
Merger  Agreement,  Apollo and Merger Co. have  requested  that the  Stockholder

     NOW,  THEREFORE,  to induce  Apollo and Merger  Co. to enter  into,  and in

applicable),  and in  consideration  of the  premises  and the  representations,
warranties and agreements contained herein, the parties agree as follows:

         1.       Purchase and Sale of Shares.

         (a) Sale.  The  Stockholder  hereby  agrees to sell to Merger Co., upon
written notice from Merger Co. (the "Notice"),  all such Stockholder's Shares at
a price per Share equal to $12.00; provided, that (i) one of the following shall
have occurred (A) a third party shall have

                                        1


made an Alternative Proposal (as defined in the LOI), (B) the Company materially
breaches  its  obligations  under  the LOI or the  Merger  Agreement  or (C) the
approval  of the  Merger  by the  Company's  stockholders  shall  not have  been
obtained at a meeting duly convened  therefor or at any adjournment  thereof and
(ii)  any  applicable  waiting  period  under  the  Hart-Scott-Rodino  Antitrust
Improvements Act of 1976 (the "HSR Act") shall have expired or been terminated.

         (b)  Closing.  Subject  to  Section  1(a)  hereof,  the  closing of the
purchase  and sale of the  Stockholder's  Shares  shall take place at the place,
time and date for the  closing of the  purchase by Merger Co.  specified  in the
Notice. At the closing, Stockholder shall deliver certificates representing such
Stockholder's  Shares, in proper form for transfer,  accompanied by stock powers
duly  executed in blank  against  delivery of the  Purchase  Price of $12.00 per
share.  Such delivery  shall vest in Merger Co., and  Stockholder  will take any
additional actions reasonably  requested by Merger Co. to perfect in Merger Co.,
good and marketable title to the Shares, free and clear of any lien, encumbrance
or voting agreement of any kind other than as may be created by this Agreement.

         (c)  Subsequent  Sale.  (i) In  the  event  Merger  Co.  purchases  the
Stockholder's  Shares as  contemplated  by Section  1(b) above and  subsequently
consummates the sale of such Shares  pursuant to (i) an Alternative  Proposal or
(ii) the Merger  Agreement,  in the event the  transactions  contemplated by the
Merger Agreement are consummated and the  consideration per Share paid by Merger
Co. is  increased  to in excess of $12.00 per Share (a "Merger  Co.  Increase"),
then Merger Co. agrees to pay to Stockholder,  on demand, an amount equal to all
Excess  Consideration  (determined in accordance  with paragraphs (ii) and (iii)
below) of Merger Co. from the consummation of any Alternative Proposal for which
a definitive  agreement is entered into within the time periods  contemplated by
Section 7 below or a Merger Co. Increase.

         (ii) For purposes of this Section 1(c), the "Excess  Consideration"  of
any Stockholder from any Alternative Proposal or Merger Co. Increase shall equal
the sum of (A)(1)  the  aggregate  consideration  received  by such  Stockholder
pursuant to such (x) Alternative  Proposal or (y) Merger Co.  Increase,  valuing
any non-cash  consideration  (including any residual interest in the Company) at
its fair market value on the date of such  consummation plus (2) the fair market
value  (which  shall not be less than the  purchase  price per share of  Company
Common Stock set forth in the Alternative  Proposal or a Merger Co. Increase) of
all Shares of such  Stockholder  disposed of after the termination of the LOI or
the Merger  Agreement and prior to the date of such  consummation,  less (B) the
product  of (x) the  number of Shares  held by such  Stockholder  on the date of
termination  of the LOI or the Merger  Agreement  and (y) $12.00.  An equivalent
calculation  shall be made with respect to any options sold and included as part
of the calculation of Excess Consideration.

         (iii) For purposes of this Section  1(c),  the fair market value of any
non-cash consideration consisting of:


                                        2



                  (A)  securities  listed on a national  securities  exchange or
traded on the New York  Stock  Exchange  shall be equal to the  average  closing
price per share of such  security as reported on such exchange or New York Stock
Exchange for the five trading days after the date of determination; and

                  (B)  consideration  which is other than securities of the form
specified  in clause (A) of this  Section  1(c)(iii)  shall be  determined  by a
nationally recognized  independent  investment banking firm mutually agreed upon
by the parties within 10 business days of the event requiring  selection of such
banking firm; provided,  however, that if the parties are unable to agree within
10 business days after the date of such event as to the investment banking firm,
then the  parties  shall each select one firm,  and those  firms shall  select a
third investment  banking firm, which third firm shall make such  determination;
provided  further,  that the fees and expenses of such  investment  banking firm
shall be borne equally by Merger Co., on the one hand, and the  Stockholder,  on
the other  hand.  The  determination  of the  investment  banking  firm shall be
binding upon the parties.

         (d)  Dividends and  Split-Ups.  In event of any change in the number of
issued  and  outstanding  Shares  by reason  of any  stock  dividend,  split-up,
recapitalization,  merger, combination,  conversion,  exchange of shares, rights
plan or other change in the corporate or capital  structure of the Company which
would have the effect of  diluting  the  rights of Merger  Co.  hereunder  or of
reducing  the  aggregate  Purchase  Price (as defined in the LOI)  payable  with
respect to the Shares  hereunder,  the number and kind of Shares subject to this
Agreement and the Purchase Price shall be appropriately adjusted.
