ITEM 4.  PURPOSE OF TRANSACTION


            AIG intends to exercise the Series A Warrants and
convert the shares of Series A Preferred Stock during the third quarter of 1998
so that it will own in excess of 50 percent of the Common Stock by the end of
such  quarter, thereby allowing AIG to account for its investment in the
Company on a consolidated basis.   

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

            (a). Between June 26, 1998 and July 7, 1998, AIG, through its
subsidiary American Home, purchased 383,500 shares of Common Stock in open
market transactions effected on the New York Stock Exchange at prices ranging
from $28.6250 to $28.9375 per share. 

            AIG has entered into a stock purchase agreement dated as of July
10, 1998 (the "Stock Purchase Agreement") with (i) Gladyce L. Foster and Robert
Scott Foster as Trustees of the Louis W. Foster and Gladyce L. Foster Revocable
Trust Dated December 10, 1991, (ii) Gregory A. Foster, (iii) R. Scott Foster,
(iv) Basil G. Witt and Judith Witt as Trustees of the Witt Family Trust Dated
June 24, 1996, (v) Christina Kirkpatrick and (vi) R. Scott Foster as Trustee of
the R. Scott Foster, M.D., Inc., 401(k) Profit Sharing Plan and  Trust, (the
"Sellers") whereby the parties agreed that AIG (directly or through one or more
of its wholly-owned subsidiaries) shall purchase from the Sellers 4,576,001
shares of Common Stock (the "Shares") for a purchase price of $29.00 per share.
The Stock Purchase Agreement provides that the closing of the purchase of the
Shares shall take place as soon as practicable following the satisfaction or
waiver of customary conditions set forth therein and the parties have agreed to
use their best efforts to assure that the closing takes place no later than
July 16, 1998. The closing under the Stock Purchase Agreement occurred with
respect to 4,376,001 Shares on July 14, 1998 and is expected to occur promptly
with respect to the remaining Shares. AIG purchased or intends to effect the
purchase of the Shares through National Union.

            American Home's, National Union's and each other AIG Sub's current
ownership interests in the Company and the Common Stock are as shown in the

                    (a) each of the Sellers shall deliver to American Stock

      Purchase Price (as hereinafter defined) for such Shares, and the
      Sellers shall use their best efforts to deliver the remaining Shares
      in proper form for transfer and settlement as soon as practicable
      thereafter, and the Purchaser shall pay the Purchase Price for such
      remaining Shares by wire transfer of federal funds to the bank or
      banks and for accounts designated by the Sellers of such Shares upon
      their delivery to the Transfer Agent; and

                    (b) Immediately upon receipt from the Transfer Agent of an
      acknowledgment that Share certificates have been delivered to the Transfer
      Agent in good order with viable instructions to the Transfer Agent to
      issue Shares to the Purchaser, the Purchaser shall deliver to the Sellers,
      by wire transfer of federal funds to a bank or banks and for accounts to
      be designated by the Sellers, Twenty-Nine dollars ($29.00) per share (the
      "Purchase Price"), for each of the Shares delivered and purchased
      hereunder. For purposes of this Section, acknowledgment by the Transfer
      Agent may be by telephone confirmation or facsimile transmission.

            Section 3. Adjustments to the Purchase Price. The Purchase Price
payable to the Sellers hereunder will be subject to adjustment as follows:

                    (a) Any dividend or other distribution (whether in cash,
      stock or otherwise) on the Shares to be sold by the Sellers pursuant
      hereto with a record date after the date of this Agreement and prior to
      the Closing Date shall be delivered by the Sellers to the Purchaser on the
      Closing Date (or as soon as practicable thereafter if the payment or
      distribution date occurs subsequent to the Closing Date); provided,
      however, that the Purchaser acknowledges and agrees that any cash dividend
      declared on the Shares with a record date prior to the date hereof but not
      paid to the Seller prior to the Closing Date shall be for the account of
      the Sellers. In the event of any merger, consolidation or other business

      Shares illegal, or (ii) impose material limitations on the ability of the
      Purchaser effectively to acquire or hold or to exercise full rights of
      ownership of the Shares acquired by it, including, but not limited to, the
      right to vote the Shares purchased by it on all matters properly presented
      to the stockholders of the Company; or

            (d) The Company shall have taken any action or shall have declared
      any form of dividend or other distribution to its stockholders that, as a
      result of the purchase of the Shares by the Purchaser, could have,
      directly or indirectly, an adverse effect on the Purchaser or diminish the
      value of (i) the Shares if they were to be beneficially owned by the
      Purchaser or (ii) any other securities, options, warrants or rights to
      purchase securities of the Company that are beneficially held by the

action to impede the Purchaser from seeking to enforce such right of specific
performance.

representations and warranties included in Section 8 shall survive the purchase
and sale of the Shares hereunder.

            Section 14. Assignment. The Purchaser may, without the consent of
the Sellers, assign its rights hereunder to any direct or indirect wholly owned
subsidiary of the Purchaser, provided that any such assignment shall not affect
the obligations of the Purchaser hereunder. The Sellers shall not have either

to any other person or entity, and any such purported assignment or delegation
shall be void.

            Section 19. Severability. The invalidity or unenforceability of any

any other provision of this Agreement, which shall remain in full force and
effect.

            Section 20. Amendment; Waiver. No amendment or waiver of any
provision of this Agreement or consent to departure therefrom shall be effective

amendment, or by the party which is the beneficiary of any such provision, in
the case of a waiver or a consent to departure therefrom.
