period shall be deemed to be agreed to by the other party. Buyer and Sellers

objections have been raised during the period of ten (10) days following receipt
of objections. Any adjustments to the Estimated Purchase Price that either party
has objected to and has not been resolved during the ten (10) day period
following the objection shall be settled in accordance with the CPA Procedure.

to each other, in immediately available funds, the amounts owed, if any, by

                            ARTICLE XIII - INDEMNITY

         13.1     SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

         All of the representations and warranties of the Sellers contained in
Article VIII or made otherwise herein or in any documents delivered in
connection with the Closing shall survive the Closing and continue in full force
and effect for a period of two (2) years (the "Survival Period") provided that
the representations contained in Sections 8.1, 8.3, 8.11, and 8.24 shall survive
indefinitely. All representations and warranties of BMHC and Buyer contained in
this Agreement or in any documents delivered in connection with the Closing
shall continue in full force and effect for the Survival Period except the
representations in Sections 9.1 and 9.2 shall survive indefinitely.

         13.2     INDEMNIFICATION AND PAYMENT OF DAMAGES BY SELLERS.

         Sellers will indemnify and hold harmless Buyer for, and will pay to
Buyer the amount of, any loss, liability, claim, damage (including incidental
and consequential damages), expense (including costs of investigation and
defense and reasonable attorneys' fees) or diminution of value, whether or not
involving a third-party claim (collectively, "Damages"), arising, directly or
indirectly, from or in connection with the following provided that the aggregate
amount of Damages from all indemnification claims must exceed a threshold of
$100,000; provided that if Damages exceed $100,000, Seller shall be responsible
for all Damages:

                  13.2.1   any breach of any of the representations, warranties,
covenants or obligations in this Agreement by Sellers, or any other certificate
or document delivered by the Company or Sellers pursuant to this Agreement;

                                       30
<PAGE>


                  13.2.2   any product shipped or manufactured by, or any
services provided by the Business prior to the Closing Date;

                  13.2.3   any claims by any person for a brokerage or finder's
fee or commission or similar payment based upon any alleged agreement with the
Company or Sellers.

To the extent any claim for indemnification is covered by applicable insurance,
Buyer agrees that the Company must first seek recovery from such insurance and
the indemnification claim shall be reduced to the extent of any such insurance
proceeds actually paid to Buyer.

         The party seeking indemnification shall be paid the amount of the claim
within ninety (90) days after submission of the claim. If there is any
disagreement on the right of the Indemnified Party to payment of the claim or
the amount of the claim, the parties shall submit the dispute to non-binding
mediation with CPA. Mediation shall occur within sixty (60) days after the
expiration of the payment date. If mediation does not result in resolution of
the claim, the parties may pursue any legal remedies available to them.

         Except with respect to Damages resulting from (1) the breach of
Sections 8.1 or 8.11 or (2) fraudulent or deliberate misrepresentations, Damages
payable by Sellers shall in no event exceed $5,000,000. Damages, other than
those arising under (1) and (2) above, shall be payable solely by reducing the
Redemption Price (in the case of a Redemption, as defined in the Operating
Agreement) or the Purchase Price (as defined in the Put Agreement, in the case
of the exercise of the Put); provided that any such Damages shall bear interest
from the time they would otherwise have been payable in cash by the Sellers
until the closing of the Redemption or Put (as applicable) at the prime rate of
interest published in THE WALL STREET JOURNAL, plus 1%, compounded monthly.
Notwithstanding the preceding, Sellers at their option may at any time pay to
Buyer all or a portion of the amount otherwise payable under this Section, in
which case the amount of the reduction in the Redemption Price or the Purchase
Price, shall be reduced by such payment.

         13.3     INDEMNIFICATION AND PAYMENT OF DAMAGES BY BMHC AND BUYER.

         BMHC and Buyer will indemnify and hold harmless Sellers, and will pay
to Sellers the amount of any Damages arising, directly or indirectly, from or in
connection with (a) any breach of any representation or warranty made by BMHC or
Buyer in this Agreement or in any certificate delivered by Buyer pursuant to
this Agreement, or (b) any breach by BMHC or Buyer of any covenant or obligation
of Buyer in this Agreement provided that the aggregate amount of Damages from
all indemnification claims must exceed the aggregate threshold of $100,000;
provided that if Damages exceed $100,000, Sellers shall be responsible for all
Damages.

         To the extent any claim for indemnification is covered by applicable
insurance, Sellers and the Company agree that the Company must first seek
recovery from such insurance, and the indemnification claim shall be reduced to
the extent of any such insurance proceeds paid to Sellers or the Company. The
party seeking indemnification shall be paid the amount of the claim within
ninety (90) days after submission of the claim. If there is any disagreement on
the

                                       31
<PAGE>


right of the Indemnified Party to payment of the claim or the amount of the
claim, the parties shall submit the dispute to non-binding mediation with CPA.
Mediation shall occur within sixty (60) days after the expiration of the payment
date. If mediation does not result in resolution of the claim, the parties may
pursue any legal remedies available to them.

         Except with respect to Damages resulting from (1) the breach of
Sections 9.1 or 9.11 or (2) fraudulent or deliberate misrepresentations, Damages
payable by Buyers shall in no event exceed $5,000,000. Damages, other than those
arising under (1) and (2) above, shall be payable solely by increasing the
Redemption Price (in the case of a Redemption, as defined in the Operating
Agreement) or the Purchase Price (as defined in the Put Agreement, in the case
of the exercise of the Put); provided that any such Damages shall bear interest
from the time they would otherwise have been payable in cash by the Buyer until
the closing of the Redemption or Put (as applicable) at the prime rate of
interest published in THE WALL STREET JOURNAL, plus 1%, compounded monthly.
Notwithstanding the preceding, Buyer at its option may at any time pay to
Sellers all or a portion of the amount otherwise payable under this Section, in
which case the amount of the increase in the Redemption Price or the Purchase
Price, shall be reduced by such payment.

         13.4     INDEMNIFICATION PROCEDURE.

                  13.4.1   Any party seeking indemnification, damages, or any
other recovery whatsoever (the "Indemnified Party") from another party or
parties (individually or collectively, the "Indemnifying Party") with respect to
any claim, demand, action, proceeding or other matter pursuant to this Agreement
or arising out of the transactions contemplated hereby (the "Claim") shall
notify the Indemnifying party of the existence of the Claim, setting forth in
reasonable detail the facts and circumstances pertaining thereto and the basis
for the Indemnified Party's right to indemnification (a "Notice of Claims"),
which Notice of Claim shall contain the following information to the extent it
is reasonably available to the Indemnified Party: (a) an estimate of the amount
then reasonably ascertainable of the alleged loss, expense or liability against
which the Indemnified Party is indemnified; (b) a description, in reasonable
detail, of the circumstances giving rise to the alleged loss, expense, or
liability; and (c) a statement identifying each party against whom a Claim is
asserted. In no event shall such notice be valid or enforceable if sent after
the Survival Period.

                  13.4.2   If any third party shall notify any Indemnified Party
with respect to any matter which may give rise to a Claim for indemnification
against the Indemnifying Party under this Agreement, then the Indemnified Party
shall notify the Indemnifying Party thereof, which notice shall set forth the
information required in Section 13.4.1 and be furnished within thirty (30) days
after the Indemnified Party's receipt of notice from the third party; provided,
however, that no delay on the part of the Indemnified Party in notifying any
Indemnifying Party shall relieve the Indemnifying Party from any liability or
obligation hereunder unless (and then solely to the extent) the Indemnifying
Party thereby is materially prejudiced by such failure to give notice. However,
in no event shall such notice be valid or enforceable if sent after the Survival
Period. If the Indemnifying Party notifies the Indemnified Party within thirty
(30) days that it will assume the defense thereof:

                                       32
<PAGE>


                           (1)      the Indemnifying Party shall defend the
Indemnified Party against the matter with counsel of its choice reasonably
satisfactory to the Indemnified Party;

                           (2)      the Indemnified Party may retain separate
counsel at its sole cost and expense (except that the Indemnifying Party will be
responsible for the fees and expenses of the separate counsel to the extent the
Indemnified Party concludes based upon advice of counsel that a conflict of
interest exists between the Indemnified Party and Indemnifying Party that there
may be one or more legal defenses available to the Indemnified Party which are
not available to the Indemnifying Party, or available to the Indemnifying Party,
but the assertion of which would be adverse to the interest of the Indemnified
Party);

                           (3)      the Indemnified Party will not consent to
the entry of any judgment or enter into any settlement with respect to the
matter without the written consent of the Indemnifying Party (not to be withheld
unreasonably); and

                           (4)      the Indemnifying Party will not consent to
the entry of any judgment or enter into any settlement which does not include a
provision whereby the plaintiff or claimant in the matter releases the
Indemnified Party from all liability with respect thereto, without the written
consent of the Indemnified Party (not to be withheld unreasonably);

                  13.4.3   If the Indemnifying Party does not notify the
Indemnified Party within thirty (30) days that it will assume the defense
thereof, then the Indemnified Party may defend against, or enter into any
settlement with respect to, the matter in any manner it reasonably may deemed
appropriate, without prejudice to any of its rights hereunder;

                  13.4.4   The Indemnified Party shall be entitled to
reimbursement for reasonable expenses, included in damages with respect to any
Claim (including, without limitation, the cost of defense, preparation and
investigation relating to such Claim) as such expenses are incurred by the
Indemnified Party;

         13.5     COOPERATION.

         The Indemnified Party and the Indemnifying Party shall each use
commercially reasonable efforts to cooperate with the other such party in
connection with the defense of third-party Claims.
