of the California Corporation Code, the parties acknowledge that under the Code
the Merger for Federal income Tax and California income tax purposes is treated
as a taxable sale of the assets of the Company, including without limitation a
promissory note from Kenyen Projects Limited dated September 29, 1995, in the
original principal amount of $19,763,000 (the "Kenyen Note") by the Company to

Company, including without limitation estimated liabilities of approximately
$32.1 million as of December 31, 1995 on a GAAP basis (including environmental
liabilities which Parent and Sub acknowledge to be approximately $23.6 million
as of December 31, 1995) and all liabilities of the Company for state and local
Taxes regardless of the party against whom such Taxes are assessed, by Sub and
$1 million in cash to be transferred by Sub to the Company for distribution to
the Shareholder. The Federal income Tax consequences of the sale of the
Company's assets will be reported on the consolidated Federal income Tax Return
of the Consolidated Group for the taxable year of the Consolidated Group in
which the sale of assets by the Company occurs and the California income tax
consequences of the sale of the Company's assets will be reported on the
Company's final California income tax return for the taxable year in which the
sale of assets by the Company occurs. Parent and Sub acknowledge and agree that
for all purposes, including but not limited to Tax reporting purposes, the
Kenyen Note will be given effect at its fair market value of $19,763,000 and
that neither of them will take or permit to be taken any action inconsistent
with such value. The consideration for the assets deemed to be sold by the
Company to Sub for Federal income Tax purposes shall be allocated among such
assets as set forth on Schedule 6.1 attached hereto, and the parties shall use
such allocation for all Tax reporting and other purposes, including without
limitation the preparation of Form 8594.

shall use their best efforts to sell such assets for the maximum available price
and will use the net proceeds received from such sales to pay or otherwise
satisfy and discharge all obligations of Sub with respect to Environmental
Claims, with any balance to be used as Parent and Sub shall determine in their
sole discretion.

          Section 8.4 Subscription. Parent shall not modify or release the
Subscription and shall enforce the terms thereof, and use its best efforts to
collect all monies due thereunder.

which is to prevent or inhibit the Surviving Corporation's ability to perform
any such obligations. Parent and Sub agree that Kenyen Projects Limited is an
intended third party beneficiary of the terms of this Section 8.5 and shall be
entitled to enforce its rights hereunder directly against Parent and the

treatment of the transactions consummated pursuant to the Asset Agreement for
Federal income tax purposes as a sale of the assets specified therein for
consideration consisting of the Kenyen Note and the other consideration
specified in the Asset Agreement is proper and that neither Parent nor Sub will
take or permit to be taken any action inconsistent with the Company's treatment

assets in the Federal income Tax Return of the Consolidated Group for the fiscal
year ended September 30, 1995.

relevant to the Arbitration and providing access to all documents, records and
other information of the Company with respect to the matters related to the

indemnify and hold the Parent Indemnitees harmless from and against any Damages
suffered by them resulting from, arising out of or incurred with respect to, or
(in the case of claims asserted against any Parent Indemnitee by a third party)
alleged to result from, arise out of or have been incurred with respect to (i)
the falsity, breach or inaccuracy of any of the warranties, representations,
covenants or agreements of Castle and/or Shareholder contained in this Merger
Agreement or in any schedule, exhibit, document or instrument delivered in
connection herewith, (ii) any and all actions, suits, proceedings, claims,
demands, assessments, judgments, costs and expenses relating to Federal Tax
liability of Castle, any Affiliate of Castle or other person or entity which
arises by reason of the Company having been joined in the filing of consolidated

(exclusive of claims for Taxes) and (iv) any and all actions, suits,
proceedings, claims, demands, assessments, judgments, costs and expenses,
including, without limitation, legal fees and expenses, incurred in enforcing
this indemnity.

          (b) The Parent shall indemnify and hold the Castle Indemnitees
harmless from and against any Damages suffered by them resulting from, arising
out of or incurred with respect to, or (in the case of claims asserted against
any Castle Indemnitee by a third party) alleged to result from, arise out of or
have been incurred with respect to (i) the falsity, breach or inaccuracy of any
representation, warranty, covenant or agreement of the Parent or Sub contained

Claims alleging Liability of the Company, (iv) any Liability whatsoever of the
Parent, Sub or the Company which are not specifically subject to indemnification
under Section 11.1(a) above, whether arising prior to, on or after the Closing
Date, including without limitation, any Liability arising out of the Parent's

                                       28

<PAGE>



          Section 11.2 Procedures Relating to Indemnification. (a) A party (the
"indemnified party") seeking indemnification under this Merger Agreement in
respect of, arising out of or involving a claim or demand made by any Person
against the indemnified party (a "Third Party Claim") shall notify the
indemnifying party in writing of the Third Party Claim within 20 days after
receipt by the indemnified party of written notice of the Third Party Claim;
provided, however, that failure to give such notification shall not affect the
indemnification provided under this Merger Agreement, except to the extent the
indemnifying party shall actually have been prejudiced by the failure.
Thereafter, the indemnified party shall deliver to the indemnifying party,
promptly after the indemnified party's receipt thereof, copies of all notices
and documents (including court papers) received by the indemnified party
relating to the Third Party Claim.

          (b) The indemnifying party shall have the right, within 30 days after
being so notified, to assume the defense of such Third Party Claim with counsel
reasonably satisfactory to the indemnified party. In any such proceeding, the
defense of which the indemnifying party shall have so assumed, the indemnified
party shall have the right to participate therein and retain its own counsel at
its own expense unless (i) the indemnified party and the indemnifying party
shall have mutually agreed to the retention of such counsel, (ii) the
indemnified party shall have received a written opinion of counsel to the effect
that there may be one or more legal defenses available to it which are different
from or additional to those available to the indemnifying party (iii) the named
parties to any such proceeding (including the impleaded parties) include both
the indemnifying party and the indemnified party, and representation of both
parties by the same counsel would be inappropriate in the opinion of the
indemnified party's counsel due to actual or potential differing interests
between them; in any such case, such separate counsel may be retained by the
indemnified party at the indemnifying party's expense (provided that the
indemnifying party shall not be required to bear the fees and expenses of more
than one such counsel). To the extent that the settlement of such a Third Party
Claim, the defense of which has been assumed by the indemnifying party, involves
the payment of money only, the indemnifying party shall have the right, in
consultation with the indemnified party, to settle those aspects dealing only
with the payment of money, provided that the indemnifying party pays such money.
In connection with any such defense or settlement, the indemnifying party shall
not enter into a consent decree involving injunctive or non-monetary relief or
consent to an injunction without the indemnified party's prior written consent.
If the indemnifying party shall have assumed the defense of a Third Party Claim,
the indemnified party shall not, without first waiving the indemnity as to such
claim, admit any liability with respect to, or settle, compromise or discharge,
the Third Party Claim without the indemnifying party's prior written consent.



                                       29

<PAGE>



          (c) With respect to all Third Party Claims, the indemnified party
shall cooperate in all reasonable respects with the indemnifying party in
connection with such claims and the defense or compromise of the claims. Such
cooperation shall include the retention and (upon the indemnifying party's
request) the provision to the indemnifying party of records and information
reasonably relevant to the Third Party Claim, making employees available on a
mutually convenient basis to provide additional information and explanation of
any material provided under this Merger Agreement.

          Section 11.3 Defense of Third-Party Claim. The failure by the
indemnifying party to notify the indemnified party of its election to defend any
Third Party Claim within 30 days after written notice thereof shall have been
given to the indemnifying party shall be deemed a waiver by the indemnifying
party of its right to defend such Third Party Claim. If the indemnifying party
shall not assume the defense of any such Third Party Claim, the indemnified
party may defend against and, subject to obtaining the consent of the
indemnifying party, which shall not be unreasonably delayed or denied, settle
such Third Party Claim in such manner as it may deem appropriate.

          Section 11.4 Payment. The indemnifying party shall pay directly all
Damages or shall, if the indemnified party elects to pay any Damages directly,
promptly reimburse the indemnified party for any Damages paid by the indemnified
party that is the subject of an indemnification given under this Article XI. The
indemnifying party shall reimburse the indemnified party promptly upon demand
for the amount of any judgment rendered or settlement entered into with respect
to any Third Party Claim, the defense of which was not assumed by the
indemnifying party, and, promptly upon demand, for all Damages paid by the
indemnified party in connection with the defense against such Third Party Claim.
