any of its material properties or assets are bound, or of any material provision

4.1 In the event upon merger the Buyer is not deemed registered under the

4.3 The right to indemnification, payment of Damages (as defined in section 4.5)
or other remedy based on any representation, warranty, covenant or obligation of
a party hereunder shall not be affected by any investigation conducted with
respect to, or any knowledge acquired (or capable of being acquired) at any
time, whether before or after the execution and delivery of this Agreement, with
respect to the accuracy or inaccuracy of or compliance with, any such
representation, warranty, covenant or obligation. 4.4 The waiver of any
condition to a party's obligation to consummate the transactions contemplated
hereunder, where such condition is based on the accuracy of any representation
or warranty, or on the performance of or compliance with any covenant or
obligation, will not affect the right to indemnification, payment of Damages, or
other remedy based on such representation, warranty, covenant or obligation. 4.5
Advanced Ceiling and each of the Sellers, jointly and severally, shall indemnify
and hold harmless the Buyer, and each of its representatives, employees,
officers, directors, stockholders, controlling persons and affiliates
(collectively, the "Buyer Indemnified Persons") for, and will pay to the Buyer
Indemnified Persons, the amount of, any loss, liability, claim, damage
(including, without limitation, incidental and consequential damages), cost,
expense (including, without limitation, interest, penalties, costs of
investigation and defense and the reasonable fees and expenses of attorneys and
other professional experts) or diminution of value, whether or not involving a
third-party claim (collectively, "Damages"), directly or indirectly arising
from, attributable to or in connection with:

     (a)  any representation or warranty made by the Sellers and Advanced
          Ceiling in this agreement or any of the Sellers' and Advanced Ceiling
          closing deliveries, that is, or was at the time made, false or
          inaccurate, or any breach of, or misrepresentation with respect to,
          any such representation or warranty; and

                                       5
<PAGE>

     (b)  any breach by any of the Sellers or Advanced Ceiling of any covenant,
          agreement or obligation of the Sellers contained in this agreement.

     (c)  any claims or litigation relating to Advanced Ceiling now pending or
          threatened or which may hereafter be brought against Buyer and/or
          Advanced Ceiling based upon events occurring prior to the date hereof
          and not attributable to the acts of the Buyer.

     (d)  any and all actions, suits, proceedings, claims, demands, assessments,
          judgments, costs, losses, liabilities and reasonable legal and other
          expenses incident to any of the foregoing.

            4.6 The Sellers and Advanced Ceiling shall have no liability for
indemnification with respect to any representation or warranty, unless, on or
before the [third] anniversary of the date hereof, the Buyer notifies the
Sellers of a claim specifying the basis thereof in reasonable detail to the
extent then known by the Buyer. A claim with respect to any covenant, agreement
or obligation contained in this agreement, may be made at any time without any
time limitation.

            4.7 Promptly after receipt by an indemnified party of written notice
(the "Notice of Claim") of the commencement of any action, suit or proceeding
against it, or written threat thereof, such indemnified party will, if a claim
is to be made against an indemnifying party under either of said sections, as
applicable, give notice to the indemnifying party of the commencement of such
action, suit or proceeding. The indemnified party shall furnish to the
indemnifying party in reasonable detail such information as the indemnified
party may have with respect to such indemnification claims (including copies of
any summons, complaint or other pleading which may have been served on it and
any written claim, demand, invoice, billing or other document evidencing or
assenting the same). Subject to the limitations set forth in this section, no
failure or delay by the indemnified party in the performance of the foregoing
shall reduce or otherwise affect the obligation of the indemnifying party to
indemnify and hold the indemnified party harmless except to the extent that such
failure or delay shall have materially and adversely affected the indemnifying
party's ability to defend against, settle or satisfy any action, suit or
proceeding the claim for which the indemnified party is entitled to
indemnification hereunder. The foregoing shall not apply to the extent
inconsistent with the provisions of section 4.8 relating to Proceedings.

            4.8 If the claim or demand set forth in the Notice of Claim given by
the indemnified party is a claim or demand asserted by a third party, the
indemnifying party shall have 30 days after the Date of Notice of Claim to
notify the indemnified party in writing of its election to defend such third
party claim or demand on behalf of the indemnified party (the "Notice Period");
provided, however, that the indemnified party is authorized to file any motion,
answer or other pleading which it deems necessary or appropriate to protect its
interests during the Notice Period. If the indemnifying party elects to defend
such third party claim or demand, the indemnified party shall make available to
the indemnifying party and its agents and representatives all records and other
materials which are reasonably required in the defense of such third party claim
or demand and shall otherwise cooperate (at the sole cost and expense of the
indemnifying party) with, and assist (at the sole cost and expense of the
indemnifying party) the indemnifying party in the defense of, such third party
claim or demand, and so long as the

                                       6
<PAGE>

indemnifying party is diligently defending such third party claim in good faith,
the indemnified party shall not pay, settle or compromise such third party claim
or demand. If the indemnifying party elects to defend such third party claim or
demand, the indemnified party shall have the right to control the defense of
such third party claim or demand, at the indemnified party's own expense. If the
indemnifying party does not elect to defend such third party claim or demand or
does not defend such third party claim or demand in good faith, the indemnified
party shall have the right, in addition to any other right or remedy it may have
hereunder at the indemnifying party's expense, to defend such third party claim
or demand.

            4.9 The term "Date of Notice of Claim" shall mean the date the
Notice of Claim is effective pursuant to section 5.5 of this Agreement.

            4.10 A claim for indemnification for any matter not involving a
third-party claim may be asserted by notice to the party from whom
indemnification is sought.

            4.11 Any legal action or proceeding with respect to this Agreement
or any matters arising out of or in connection with this Agreement or the
transactions contemplated hereby or the documents executed and delivered in
connection herewith, and any action for enforcement of any judgment in respect
thereof may be brought in the courts of the State of New York or of the United
States of America for the Southern District of New York, and, by execution and
delivery of this Agreement, the parties each hereby accepts for itself and in
respect of its property, generally and unconditionally, the jurisdiction of the
aforesaid courts and appellate courts thereof. The parties irrevocably consent
to service of process out of any of the aforementioned courts in any such action
or proceeding in accordance with the notice provisions set forth in Section 5.5.
The parties each hereby irrevocably waive any objection that it may now or
hereafter have to the laying of venue of any of the aforesaid actions or
proceedings arising out of or in connection with this Agreement or the
transactions contemplated hereby or the documents execute and delivered in
connection herewith brought in the courts referred to above and hereby further
irrevocably waive and agree, to the extent permitted by applicable law, not to
plead or claim in any such court that any such action or proceeding brought in
any such court has been brought in an inconvenient forum. Nothing herein shall
affect the right of any party hereto to serve process in any other manner
permitted by law.
