                           For purposes of the calculating EBIT for the Second
                           Period, the parties hereto agree that EBIT for the
                           First Period shall be $4 million.

                  3. Section 1.3(b) of the Agreement is hereby amended to read
         in its entirety as follows:

                           (b) For purposes of this Agreement, "EBIT" shall mean
                  earnings of all three of the Companies, before interest and
                  taxes. EBIT for the period of July 1, 1999 to December 31,
                  1999 shall be calculated in accordance with the rules and
                  regulations set forth in Exhibit 3 attached hereto and in
                  accordance with Section 1.3 (c) of the Agreement.

                  4. Section 1.3 (f) of the Agreement is hereby terminated in
         its entirety.

                  5. The parties hereto agree that AHC agrees that the
         Shareholders, in their sole discretion and determination, may, upon
         written notice to AHC, determine the method for calculating earnings
         for purposes of the Employee Pool to allow employees to obtain an equal
         or greater percentage of the total available Employee Pool as compared
         to the Shareholders; provided, however that the size of the Employee
         Pool shall not be changed.

                  6. The parties hereto agree that, at any time during the
         period of October 1, 2000, through April 1, 2001, AHC shall have the
         right to redeem all or any portion of the shares of AHC Preferred Stock
         issued to the Shareholders of R-Anell pursuant to Section 2 above at a
         redemption price of $12.00 per share, payable in cash. In order to make
         any such redemption, AHC shall give written notice of such redemption
         to the Shareholders of R-Anell at least fourteen (14) days prior to the
         date of such redemption, and each Shareholder shall have the right,
         prior to such stated redemption date, to convert each of its shares of
         AHC Preferred Stock into one share of Common Stock of AHC (subject to
         adjustment as provided in the Certificate of Designations).

         B.       MISCELLANEOUS.

                  1. AHC hereby represents and warrants to the Shareholders as
         follows:

                           (a) The Series A Stock to be issued hereunder will,
                  when issued, be duly authorized, validly issued, fully paid
                  and nonassessable.

                           (b) Since May 31, 1995, AHC has filed all forms,
                  documents and reports with the SEC required to be filed by it
                  pursuant to federal securities laws and the SEC rules and
                  regulations thereunder (the "SEC Reports"), all of which
                  complied in all material respects with all applicable
                  requirements of the Securities Act and the Exchange Act. The
                  SEC Reports do not contain any untrue statement of a material
                  fact or omit to state a material fact required to be stated
                  therein to make statements contained therein not misleading.
                  AHC will take all steps necessary by AHC to enable the
                  Shareholders to be eligible to sell shares of Common Stock of
                  AHC underlying the Series A Stock under Rule 144 of the
                  Securities Act on and after October 1, 2000.

                           (c) The execution, delivery and performance of this
                  Third Amendment have been approved and authorized by AHC, and
                  this Third Amendment is enforceable against AHC in accordance
                  with its term, except as may be limited by applicable
                  bankruptcy, insolvency or similar laws affecting creditors'
                  rights generally or the availability of equitable remedies.

                           (d) As of May 31, 1999, AHC had authorized (i)
                  50,000,000 shares of Common Stock, 18,412,900 shares of which
                  were issued and outstanding; and (ii) 5,000,000 shares of
                  Preferred Stock, none of which share were issued and
                  outstanding. Between May 31, 1999 and September 29, 1999, the
                  Company has not increased its authorized shares of Common
                  Stock or Preferred Stock, has not issued a material amount of
                  Common Stock, has not issued any shares of Preferred Stock,
                  and has authorized the issuance of up to 1,000,000 shares of
                  Series A Stock.

                  2. The Shareholders acknowledge and agree that between
         December 28, 1998, and the date hereof, the Companies have been
         operated in a manner consistent with the terms and provisions of
         Section 1.3 (c) of the Agreement.

                  3. Except as specifically provided herein, the Agreement shall
         remain in full force and effect.

                  4. This Third Amendment may be executed in two or more
         counterparts, each of which shall be deemed an original, but all of
         which together shall constitute one and the same instrument.


                                        4

         IN WITNESS WHEREOF, the parties hereto have executed this Third
Amendment as of the date first above written.
