                            INDEMNIFICATION BY SELLER

9.1      INDEMNIFICATION GENERALLY. From and after the Closing Date, Seller
         shall indemnify and hold Purchaser harmless against and from any and
         all costs, expenses, losses, damages and liabilities (including,
         without limitation, reasonable attorneys' fees) incurred by Purchaser
         with respect to or in connection with any breach of any of the
         representations and warranties of Seller under this Agreement
         (hereinafter, the "PURCHASER'S LOSSES" and each a "PURCHASER'S LOSS").
         Notwithstanding anything to the contrary contained in this Agreement,
         Seller shall have no indemnification obligations to Purchaser under
         this Article 9 with respect to any claim made by Purchaser for any
         Purchaser's Loss, whether or not arising as a result of a claim made by
         a third party, of which Seller is notified after the first anniversary
         of the Closing Date.

9.2      INDEMNIFICATION RIGHTS FOR DIRECT CLAIMS. In order to be held
         indemnified and harmless against and from Purchaser's Losses under this
         Article 9 (other than Purchaser's Losses arising from a claim made by a
         third party, as to which Section 9.3 shall apply):

         (a) Purchaser shall give written notice to Seller of any claim (the
         "PURCHASER'S INDEMNIFICATION Claim"), which notice shall set forth a
         reasonably detailed statement of the Purchaser's Indemnification Claim
         and the cost, expense, loss, damage and liability Purchaser incurred
         and/or expects to incur by reason thereof;

         (b) such indemnification payment shall be made on the later of (i) the
         expiration of thirty (30) days from the date of such notice
         (hereinafter, the "PURCHASER'S NOTICE OF CONTEST PERIOD") or, (ii) if
         such claim is contested as hereinafter provided, the date the dispute
         is resolved in accordance with this Section 9.2, or (iii) the date in
         which such Purchaser's Indemnification Claim becomes liquidated in
         amount; and

         (c) if, prior to the expiration of the Purchaser's Notice of Contest
         Period, Seller notifies Purchaser in writing of his intention to
         dispute the Purchaser's Indemnification Claim, and if such dispute is
         not resolved within thirty (30) days after the expiration of such
         period (hereinafter, the "PURCHASER'S RESOLUTION PERIOD"), then such
         dispute shall be resolved by a committee of three arbitrators who shall
         be appointed (within 60 days of the expiration of the Purchaser's
         Resolution Period) and shall be acting in accordance with Section 12.9
         below. The Parties shall cooperate and diligently pursue the
         arbitration of such Purchaser's Indemnification Claim in order for a
         decision to be made by the arbitrators within 45 days after their
         appointment.

9.3      PURCHASER'S INDEMNIFICATION CLAIMS FOR THIRD PARTY CLAIMS. The
         provisions of this Section shall apply to any Purchaser's Losses which
         arise or may arise as a 



                                      -18-
   13

         result of a claim made by a third party and any related litigation or
         proceeding (hereinafter, the "THIRD PARTY CLAIM").

         (a) Purchaser shall give notice to Seller promptly after Purchaser
         becomes aware of any Third Party Claim, which notice shall include a
         copy of any letter, complaint or similar writing received by Purchaser
         and/or FOREM or any of FOREM's consolidated subsidiaries setting out
         such Third Party Claim or a written description of any oral notice
         received by Purchaser or FOREM or any of FOREM's consolidated
         subsidiaries; PROVIDED, HOWEVER, that any delay in providing such
         notification shall not constitute a bar or defense to indemnify except
         to the extent Seller has been prejudiced thereby.

         (b) Within ten (10) days from the date of such notice, Seller shall
         notify Purchaser in writing if he intends to dispute that such Third
         Party Claim constitutes or will constitute Purchaser's Losses subject
         to indemnification hereunder (hereinafter, the "SELLER'S DISPUTE
         NOTICE"). If the Seller's Dispute Notice is given within said ten (10)
         day period, the issue of whether such Third Party Claim constitutes or
         will constitute Purchaser's Losses subject to indemnification hereunder
         may be submitted to arbitration in accordance with Section 12.9 hereof
         unless an agreement is subsequently reached between the Parties.

         (c) For the purpose of this Paragraph (c) and subsequent Paragraphs (d)
         and (e) of this Section 9.3 the defense of a Third Party Claim by
         either Purchaser or Seller shall include, as the case may be, the
         Purchaser's or the Seller's right to designate counsel to be employed
         by Purchaser or FOREM or any of FOREM's consolidated subsidiaries in
         defending the Third Party Claim and to provide such counsel with
         instructions with respect to the defense thereof, as well as the power
         to settle the Third Party Claim on behalf of Purchaser or FOREM or any
         of FOREM's consolidated subsidiaries in the cases and subject to the
         conditions set forth by this Section 9.3. If a Seller's Dispute Notice
         with respect to a Third Party Claim is given then: (i) Purchaser shall
         have the right to defend such Third Party Claim and the costs of such
         defense shall be added to Purchaser's Losses, (ii) Seller shall have
         the right to participate in the defense of the Third Party Claim at his
         own costs and expenses provided that such right is not exercised in a
         way which may prejudice the Purchaser's defense of the Third Party
         Claim, and (iii) Purchaser shall consult with Seller prior to reaching
         a settlement of the Third Party Claim, if any.

         (d) Seller shall have the right to assume the defense of a Third Party
         Claim unless:

         (i) a Seller's Dispute Notice is sent to Purchaser pursuant to
         Paragraph 9.3 (b) hereof; or


                                      -19-
   14

         (ii) the named parties to any action constituting such Third Party
Claim (including any impleaded parties) include Seller or any member of the
Seller's family or any party belonging to a group in which Seller may have a
business interest.

         (e) In order for Seller to exercise the right to assume the defense of
         a Third Party Claim, Seller shall give notice to Purchaser within ten
         (10) days after receipt of the notice of the Third Party Claim as to
         which no Seller's Dispute Notice was given. If Seller fails to notify
         Purchaser within such period, Seller shall be deemed to have waived his
         right to defend such Third Party Claim and Purchaser shall have the
         right to defend such Third Party Claim and its costs and expense shall
         be added to the Purchaser's Losses. If Purchaser assumes the defense of
         a Third Party Claim pursuant to this paragraph (e), Purchaser may not
         settle such Third Party Claim without the consent of Seller, which
         consent cannot be unreasonably withheld. If Seller assumes the defense
         of such Third Party Claim then: (i) Purchaser may participate in the
         defense of such claim with its own counsel at its own cost and expense,
         (ii) Seller may settle such Third Party Claim without the consent of
         Purchaser provided such settlement includes an unconditional release of
         Purchaser and its subsidiaries from all liability with respect to any
         Third Party Claim and does not involve the imposition of any
         restriction or obligation on Purchaser or any of its subsidiaries, and
         (iii) Seller may not consent to the entry of any judgment (other than a
         judgment of dismissal on the merits) except with the written consent of
         Purchaser.

                                   ARTICLE 10
                          INDEMNIFICATION BY PURCHASER

10.1     INDEMNIFICATION GENERALLY. From and after the Closing Date, Purchaser
         shall indemnify and hold Seller harmless against and from any and all
         costs, expenses, losses, damages and liabilities (including, without
         limitation, reasonable attorneys' fees) incurred by Seller with respect
         to or in connection with any breach of any of the representations and
         warranties of Purchaser under this Agreement (hereinafter, the
         "SELLER'S LOSSES" and each a "SELLER'S LOSS").Notwithstanding anything
         to the contrary contained in this Agreement, Purchaser shall have no
         indemnification obligations to Seller under this Article 10 with
         respect to any claim made by Seller for any Seller's Loss, whether or
         not arising as a result of a claim made by a third party, of which
         Purchaser is notified after the first anniversary of the Closing Date.

10.2     INDEMNIFICATION RIGHTS FOR DIRECT CLAIMS. In order to be held
         indemnified and harmless against and from Seller's Losses under this
         Article 10 (other than Seller's Losses arising from a claim made by a
         third party, as to which Section 10.3 shall apply):

   15

         (a) Seller shall give written notice to Purchaser of any claim (the
         "SELLER'S INDEMNIFICATION CLAIM"), which notice shall set forth a
         reasonably detailed statement of the Seller's Indemnification Claim and
         the cost, expense, loss, damage and liability Seller incurred and/or
         expects to incur by reason thereof;

         (b) such indemnification payment shall be made on the later of (i) the
         expiration of thirty (30) days from the date of such notice
         (hereinafter, the "SELLER'S NOTICE OF CONTEST PERIOD") or, (ii) if such
         claim is contested as hereinafter provided, the date the dispute is
         resolved in accordance with this Section 10.2, or (iii) the date in
         which such Seller's Indemnification Claim becomes liquidated in amount;
         and

         (c) if, prior to the expiration of the Seller's Notice of Contest
         Period, Purchaser notifies Seller in writing of its intention to
         dispute the Seller's Indemnification Claim, and if such dispute is not
         resolved within thirty (30) days after the expiration of such period
         (hereinafter, the "SELLER'S RESOLUTION PERIOD"), then such dispute
         shall be resolved by a committee of three arbitrators who shall be
         appointed (within 60 days of the expiration of the Seller's Resolution
         Period) and shall be acting in accordance with Section 12.9 below. The
         Parties shall cooperate and diligently pursue the arbitration of such
         Seller's Indemnification Claim in order for a decision to be made by
         the arbitrators within 45 days after their appointment.

10.3     SELLER'S INDEMNIFICATION CLAIMS FOR THIRD PARTY CLAIMS. The provisions
         of this Section shall apply to any Seller's Losses which arise or may
         arise as a result of a Third Party Claim.

         (a) Seller shall give notice to Purchaser promptly after Seller becomes
         aware of any Third Party Claim, which notice shall include a copy of
         any letter, complaint or similar writing received by Seller setting out
         such Third Party Claim or a written description of any oral notice
         received by Seller; PROVIDED, HOWEVER, that any delay in providing such
         notification shall not constitute a bar or defense to indemnify except
         to the extent Purchaser has been prejudiced thereby.

         (b) Within ten (10) days from the date of such notice, Purchaser shall
         notify Seller in writing if it intends to dispute that such Third Party

         indemnification hereunder may be submitted to arbitration in accordance
         with Section 12.9 hereof unless an agreement is subsequently reached
         between the Parties.

         (c) For the purpose of this Paragraph (c) and subsequent Paragraphs (d)
         and (e) of this Section 10.3 the defense of a Third Party Claim by
         either Seller or Purchaser shall include, as the case may be, the
         Seller's or the Purchaser's right 



                                      -21-
   16

         to designate counsel to be employed by Seller in defending the Third
         Party Claim and to provide such counsel with instructions with respect
         to the defense thereof, as well as the power to settle the Third Party
         Claim on behalf of Seller in the cases and subject to the conditions
         set forth by this Section 10.3. If a Purchaser's Dispute Notice with
         respect to a Third Party Claim is given then: (i) Seller shall have the
         right to defend such Third Party Claim and the costs of such defense
         shall be added to Seller's Losses, (ii) Purchaser shall have the right
         to participate in the defense of the Third Party Claim at its own costs
         and expenses provided that such right is not exercised in a way which
         may prejudice the Seller's defense of the Third Party Claim, and (iii)
         Seller shall consult with Purchaser prior to reaching a settlement of
         the Third Party Claim, if any.

         (d) Purchaser shall have the right to assume the defense of a Third
         Party Claim unless:

         (i) a Purchaser's Dispute Notice is sent to Seller pursuant to
Paragraph 10.3 (b) hereof; or

         (ii) the named parties to any action constituting such Third Party
Claim (including any impleaded parties) include Purchaser or any party belonging
to a group in which Purchaser may have a business interest.

         (e) In order for Purchaser to exercise the right to assume the defense
         of a Third Party Claim, Purchaser shall give notice to Seller within
         ten (10) days after receipt of the notice of the Third Party Claim as
         to which no Purchaser's Dispute Notice was given. If Purchaser fails to
         notify Seller within such period, Purchaser shall be deemed to have
         waived its right to defend such Third Party Claim and Seller shall have
         the right to defend such Third Party Claim and its costs and expense
         shall be added to the Seller's Losses. If Seller assumes the defense of
         a Third Party Claim pursuant to this paragraph (e), Seller may not
         settle such Third Party Claim without the consent of Purchaser, which
         consent cannot be unreasonably withheld. If Purchaser assumes the
         defense of such Third Party Claim then: (i) Seller may participate in
         the defense of such claim with its own counsel at its own cost and
         expense, (ii) Purchaser may settle such Third Party Claim without the
         consent of Seller provided such settlement includes an unconditional
         release of Seller from all liability with respect to any Third Party
         Claim and does not involve the imposition of any restriction or
         obligation on Seller, and (iii) Purchaser may not consent to the entry
         of any judgment (other than a judgment of dismissal on the merits)
         except with the written consent of Seller.
