appointed within 60 days of the expiration of the Resolution Period and shall

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

         (b) Within ten (20) days from the date of such notice to the Seller,
the Seller shall notify the Purchaser in writing if he intends to dispute that
such Third Party Claim constitutes or will constitute a Loss subject to
indemnification hereunder (the "DISPUTE NOTICE"). If the Dispute Notice is
given within said twenty (20) day period, the issue of whether such Third Party
Claim constitutes or will constitute a Loss subject to indemnification

Third Party Claim: (i) the Purchaser shall have the right to defend such Third
Party Claim and the costs of such defense, including, without limitation, the

<PAGE>   23
Losses, (ii) the Seller 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 could prejudice the Purchaser's defense of the
Third Party Claim, and (iii) the Purchaser shall consult with the Seller prior
to reaching a settlement of the Third Party Claim, if any.

         (d) In order for the Seller to exercise the right to participate in
the defense of a Third Party Claim, the Seller shall give notice to the
Purchaser within twenty (20) days after receipt of the notice of the Third
Party Claim as to which no Dispute Notice was given. If the Seller fails to
notify the Purchaser within such period, the Seller shall be deemed to have
waived his right to defend such Third Party Claim and the Purchaser shall have
the right to defend such Third Party Claim, and its costs and expense,
including without limitation the fees and expenses of counsel and other
professionals shall be deemed to be  Losses.

other than Losses arising out of Third Party Claims (as hereinafter defined)
under Section 9.4:

         (a) the Purchaser shall give written notice to the Seller  of any
claim (the "INDEMNIFICATION CLAIM"), which notice shall set forth a reasonably
detailed statement of the Indemnification Claim and the cost, expense, loss,
damage and liability the Purchaser and/or Verplast 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 (the "NOTICE
PERIOD") or, (ii) if such claim is contested as hereinafter provided, within 10
days from the date in which the dispute is resolved in accordance with this
Section 9.3, or (iii) within 10 days from  the date in which such

days after the expiration of the Notice Period (the "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 Resolution Period and shall

Section shall apply to any Losses which arise or may arise as a result of a
claim made by a third party and any related Litigation or similar process or
proceeding ("THIRD PARTY CLAIM").

         (a) the Purchaser or the Designated Purchaser shall give notice to the
Seller promptly after the Purchaser or the Designated Purchaser becomes aware
of any Third Party Claim, which notice shall include a copy of any letter,
complaint or similar writing received by the Purchaser, Designated Purchaser
<PAGE>   43
and/or Verplast setting out such Third Party Claim or a written description of
any oral notice received by such party; provided, however, that any delay in
providing such notification shall not constitute a bar or defense to indemnify
except to the extent the Seller has been prejudiced thereby.

         (b) Within ten (20) days from the date of such notice to the Seller,
the Seller shall notify the Purchaser in writing if he intends to dispute that
such Third Party Claim constitutes or will constitute a Loss subject to
indemnification hereunder (the "DISPUTE NOTICE"). If the Dispute Notice is

Party Claim and the costs of such defense, including, without limitation, the
fees and expenses of counsel and other professionals, shall be deemed to be

the defense of a Third Party Claim, the Seller shall give notice to the
Purchaser within twenty (20) days after receipt of the notice of the Third
Party Claim as to which no Dispute Notice was given. If the Seller fails to
notify the Purchaser within such period, the Seller shall be deemed to have
waived his right to defend such Third Party Claim and the Purchaser shall have
the right to defend such Third Party Claim, and its costs and expense,
including without limitation the fees and expenses of counsel and other
professionals shall be deemed to be  Losses.

       (i) All the employment contracts to which Verplast is a party are in
compliance with all applicable laws and regulations and Collective Bargaining
Agreements (including Company Agreements). All obligations deriving from the
applicable Collective Bargaining Agreements in force have been duly fulfilled.
There are no economic or legal conditions which are not expressed in the above
employment contracts or Collective Bargaining Agreements (in particular, but

truly, completely and accurately summarizes their current position, TFR and
applicable benefits, if any.

       (ii) Verplast  always has been and is currently in full compliance with

any laws and regulations concerning accident prevention, safety and hygiene at
work, and to this regard, except as disclosed in Annex 6.21 (b), Verplast has
not been notified nor is it aware of any warnings, assessments or pending
proceedings. No allegation, charge, claim or complaint of age, disability, sex
or race discrimination or similar charge, claim or request of recognition of
the employee status by a self-employed person or any other person not included
in the payroll of Verplast has been made to Verplast or in any way threatened

Closing Financial Statements.

Seller aware, that any of its customers and/or suppliers intend to cease doing
business with it or to reduce the amount of goods or services purchased and/or
sold on a regular on-going basis from or to it, the cessation or reduction of
which could have a material Adverse Effect.  As far as supplies are concerned,
Verplast has not experienced in the past 12 months any material shortage of
supplies or any price increase in such supplies (unless due to significant
variation of the exchange rate between the Italian Lira and the other major
currencies) or changes in terms of dealing with any of its customers or
suppliers, which can be reasonably expected to have a material Adverse Effect.

<PAGE>   62




       (i) in respect of Loss(es) suffered under Section 9.1 (a) above, the
Purchaser's right to indemnification shall lapse if no notice of an
Indemnification Claim shall have been given to the Seller on or before December

Agreement, in which case the applicable statutory limitation period (periodo di
prescrizione) shall apply;

       (ii) in respect of Loss(es) suffered under Section 9.1 (b), (c), (d) and
(e) above, the Purchaser's right to indemnification shall lapse if no
Indemnification Claim is notified to the Seller on or before the date in which
the applicable statutory limitation period (periodo di prescrizione) will
lapse;


9.3    INDEMNIFICATION PROCEDURE. In order for the Purchaser to be indemnified
and held harmless against and from Losses under this Section 9 other than
Losses arising out of Third Party Claims (as hereinafter defined) under Section
9.4:

       (a) the Purchaser shall give written notice to the Seller  of any claim
(the "INDEMNIFICATION CLAIM"), which notice shall set forth a reasonably
detailed statement of the Indemnification Claim and the cost, expense, loss,
damage and liability the Purchaser and/or Verplast 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 (the "NOTICE
PERIOD") or, (ii) if such claim is contested as hereinafter provided, within 10
days from the date in which the dispute is resolved in accordance with this
Section 9.3, or (iii) within 10 days from  the date in which such
Indemnification Claim becomes liquidated in amount; and

       (c) if, prior to the expiration of the Notice of Period, the Seller
notifies the Purchaser in writing of his intention to dispute the
Indemnification Claim, and if such dispute is not resolved within thirty (30)
days after the expiration of the Notice Period (the "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 Resolution Period and shall
act in accordance with Section 10.10 below. The parties shall cooperate and
diligently pursue the arbitration of such Indemnification Claim in order for a
decision to be made by the arbitrators within 45 days after their appointment.

9.4    INDEMNIFICATION CLAIMS FOR THIRD PARTY CLAIMS. The provisions of this
Section shall apply to any Losses which arise or may arise as a result of a
claim made by a third party and any related Litigation or similar process or

       (a) the Purchaser or the Designated Purchaser shall give notice to the
Seller promptly after the Purchaser or the Designated Purchaser becomes aware
of any Third Party Claim, which notice shall include a copy of any letter,
complaint or similar writing received by the Purchaser, Designated Purchaser
<PAGE>   63




and/or Verplast setting out such Third Party Claim or a written description of
any oral notice received by such party; provided, however, that any delay in
providing such notification shall not constitute a bar or defense to indemnify
except to the extent the Seller has been prejudiced thereby.

       (b) Within ten (20) days from the date of such notice to the Seller, the
Seller shall notify the Purchaser in writing if he intends to dispute that such
Third Party Claim constitutes or will constitute a Loss subject to
indemnification hereunder (the "DISPUTE NOTICE"). If the Dispute Notice is
given within said twenty (20) day period, the issue of whether such Third Party
Claim constitutes or will constitute a Loss subject to indemnification
hereunder may be submitted to arbitration in accordance with Section 10.10
hereof, unless an agreement is subsequently reached between the Parties.

       (c) For the purpose of this Section 9.4, in the case of a defence of a
Third Party Claim: (i) the Purchaser shall have the right to defend such Third
Party Claim and the costs of such defense, including, without limitation, the
fees and expenses of counsel and other professionals, shall be deemed to be
Losses, (ii) the Seller 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 could prejudice the Purchaser's defense of the
Third Party Claim, and (iii) the Purchaser shall consult with the Seller prior
to reaching a settlement of the Third Party Claim, if any.

       (d) In order for the Seller to exercise the right to participate in the
defense of a Third Party Claim, the Seller shall give notice to the Purchaser
within twenty (20) days after receipt of the notice of the Third Party Claim as
to which no Dispute Notice was given. If the Seller fails to notify the
Purchaser within such period, the Seller shall be deemed to have waived his
right to defend such Third Party Claim and the Purchaser shall have the right
to defend such Third Party Claim, and its costs and expense, including without
limitation the fees and expenses of counsel and other professionals shall be
deemed to be  Losses.
