terminated or the Close of Escrow fails to occur by reason of Buyer's default
hereunder, the Deposit (including all interest thereon) shall constitute
liquidated damages pursuant to Section 6.2 below. In the event this Agreement is

holders whose lien rights and security interests are, as of the Close of Escrow,
senior and prior to Buyer's rights to and under the appurtenant easements
described in Exhibit A attached hereto, and (viii) Seller will use best efforts
             ---------

              -----------
to disclose if the Real Property lies within the following natural hazard areas
or zones: (i) a special flood hazard area designated by the Federal Emergency
Management Agency (California Civil Code Section 1102.17); (ii) an area of
potential flooding (California Government Code Section 8589.4); (iii) a very
high fire hazard severity zone (California Government Code Section 51183.5);
(iv) a wild land area that may contain substantial forest fire risks and hazards
(Public Resources Code Section 4136); (v) an earthquake fault zone (Public
Resources Code Section 2621.9); or (vi) a seismic hazard zone (Public Resources
Code Section 2694). Buyer and Seller acknowledge that Seller has employed the
services of Vista Environmental (which, in such capacity is herein called
"Natural Hazard Expert") to examine the maps and other information specifically
 ---------------------
made available to the public by government agencies for the purpose of enabling
Seller to fulfill its disclosure obligations with respect to the natural hazards
referred to in California Civil Code Section 1102.6c(a) and to report the result
of its examination to Buyer and Seller in writing. The written report prepared
by the Natural Hazard Expert and delivered to Buyer regarding the results of its
examination fully and completely discharges Seller from its disclosure
obligations referred to herein, and, for the purpose of this Agreement, the
provisions of Civil Code Section 1102.4 regarding the non-liability of each of
Seller for errors or omissions not within its personal knowledge shall be deemed
to apply and the Natural Hazard Expert shall be deemed to be an expert, dealing
with matters within the scope of its expertise with respect to the examination
and written report regarding the natural hazards referred to above. Seller shall
not have any responsibility for matters not actually known to Seller. In
addition, Seller has disclosed to Buyer or its consultants, to the extent it has
actual knowledge, all material issues regarding the Real Property and the
environmental condition of the Adjacent Property, including those involving
environmental conditions and asserted environmental claims, and those contained
in privileged documents. Buyer acknowledges that certain pre-October 4, 1988
documents are contained in boxes which are not well-indexed and which Buyer will
have to review at its expense.

          7.6 Contracts.  Other than as set forth on Exhibit H attached hereto,
              ---------                              ---------
there are no service, maintenance, employment, supply, management or other
agreements affecting the Property, either oral or written, which will remain in
effect after the Close of Escrow. Notwithstanding the foregoing, it shall not be
a default hereunder if Seller has in good faith failed to disclose one or more
of such agreements so long as no one such agreement has a post Close of Escrow
obligation of more than Five Thousand Dollars ($5,000) and all of such

                                       23
<PAGE>

foregoing agreements in the aggregate do not have a post Close of Escrow
obligation of more than Twenty-Five Thousand Dollars ($25,000).

          7.7  Leases.  Other than as set forth on Exhibit V attached hereto or
               ------                              ---------
in the PTR, there are no leases, licenses or other agreements permitting the use
or occupancy of the Real Property, which will remain in effect after the Close
of Escrow. Other than as set forth on Exhibit V attached hereto or in the PTR,
                                      ---------
to Seller's actual knowledge there are no persons entitled to use or occupy the
Real Property or any portion thereof by reason of any easements by prescription
or necessity.

involuntary petition by its creditors; (c) suffered the appointment of a

assets. Buyer acknowledges that, in 1987, Seller (which was then known as Kaiser
Steel Corporation) filed a voluntary Petition for Reorganization under Chapter
11 of the United Bankruptcy Code and the Order of the United States Bankruptcy
Court approving Seller's Plan of Reorganization was entered on the docket on
October 4, 1988.

          7.9  No Other Agreements to Convey.  Except as set forth in Exhibit W
               -----------------------------                          ---------

of the Real Property or any portion thereof, including any right of access to
the Real Property; (b) any government plans for public improvements that might
result in a special assessment against the Real Property; (c) any underground or
above-ground storage tanks on the Real Property not previously disclosed to
Buyer in writing or referenced in the records previously made available to
Buyer; or (d) any pending or threatened change in the zoning of the Real
Property.

          7.12 No Approvals Needed.  Other than the approvals and consents
               -------------------
described in Exhibit S attached hereto, the sale of the Real Property and the
             ---------
performance of Seller's obligations hereunder are not subject to any requirement
to obtain any approval or consent of any governmental agency or third party.

          7.13 Documents, Files and Records.  The files, records and other

documents delivered or made available to Buyer or its consultants pursuant to

                    ------------------
Property and the Adjacent Property were formerly used for Steel Mill Operations

other occupants; and (b) Hazardous Substances were placed, may have spilled,
leaked, seeped or entered onto or under the ground, air, water or groundwater
and Hazardous Substances are present at, under, above or adjacent to and/or
emanating to or from the Real Property and/or other real property in the
vicinity of the Real Property (including, without limitation, the Adjacent
Property). Buyer acknowledges that, following the Close of Escrow, Buyer shall
have the obligation to investigate, remove, remediate, monitor and clean up such
Hazardous Substances as provided more specifically in this Article 10. Buyer has
evaluated and is familiar with the potential magnitude of remediation of
Hazardous Substances contamination at, under, above, adjacent and/or emanating

financial resources necessary to purchase the Property pursuant to this
Agreement and to carry out such remediation (including ongoing continuing
operations and maintenance obligations) of Hazardous Substances according to all

under this Agreement. Buyer acknowledges that Seller's disclosures hereunder

and any financial assurances given by Kaiser in connection therewith provided
that Seller shall pay any expenses which may be incurred by Buyer post-closing
in connection with such cooperation (other than Buyer's or Buyer's affiliates'
internal overhead expenses). Seller acknowledges and agrees that the DTSC's
refusal to terminate the Kaiser Consent Order or to substitute Seller's

affiliates and subsidiaries and each of their officers, directors, employees,
agents and representatives shall refrain from any communications or discussions
with any Agency or any third party, and from taking any other action, which
could result in any Agency requesting or requiring Buyer or the owner of the
Real Property or the Adjacent Property to take, perform or cease any activity on
or with respect to the Real Property or the Adjacent Property. Seller shall be
entitled, so long as Buyer's representatives have the opportunity to be present
after reasonable notice thereof, to meet or have conversations with the DTSC
regarding (i) termination of the Kaiser Consent Order; (ii) elimination of the
public hearing requirement regarding closure of the Speedway site under the
Buyer Consent Order and (iii) remediation of the Tar Pits Property. Seller shall
deliver a copy of any and all notices and correspondence received from any
Agency to Buyer within two (2) business days after receipt thereof. Seller
acknowledges that, as an inducement to providing the indemnities in Section
10.3.4, below, Buyer is relying on Seller's covenant and agreement to permit
Buyer to complete all aspects of the Corrective Action, including any
communications with applicable Agencies. The provisions of this Section 10.2.4
shall not be deemed to prohibit Seller or Seller's affiliates from engaging in
communications or discussions with any Agency with respect to (i) the MRF's
operations, (ii) the Excluded Liabilities or (iii) any activities described in
Section 10.2.2, above, so long as, in each event, such communications or
discussions do not materially impact the Corrective Action to be performed by
Buyer hereunder. Seller shall not be deemed to have engaged in a communication
or discussion in breach of this Agreement as a result of a material impact on
the Corrective Action arising out of a communication or discussion with an
Agency otherwise permitted under clauses (i), (ii) or (iii), above, if Seller or
its applicable affiliate could not reasonably have anticipated the material
impact and Seller provides Buyer with prompt notice of the communication or
discussion and provides Buyer with an opportunity to participate in any follow
up communications or discussions.

the Agency having jurisdiction over the Corrective Action or by applicable Laws;
provided, however, that Seller shall pay for the incremental cost and expense of
remediating the Tar Pits Property as provided in Section 10.7 hereof.

is permitted; or (ii) upon Buyer's Default (as hereinafter defined); or (iii) in
connection with Seller's enforcement of the performance bond or the IT Contract
in accordance with the terms hereof and thereof. Until (i) receipt of a NFA
Letter, (ii) an Agency determination that an NFA Letter is not required for the

clean up cost coverage under the Real Estate Environmental Insurance Policy
referred to in Section 10.5.1.3, below, Buyer shall keep Seller reasonably
informed of the progress of each Corrective Action (other than ongoing
operations and maintenance) being performed or planned at the Real Property, the

other remediation, by delivering written status reports to Seller at least once

(c) the existence of any threat to health, safety or the environment under any
Laws, or the presence or alleged presence or release of any Hazardous Substances

recoverable from Seller which third party consequential damages shall be
recoverable hereunder); (f) any breach of the IT Contract or the performance and
completion bond, as defined in Section 10.4 below and (g) personal injury,
including death and disability, occurring on or after the Close of Escrow caused

the Real Property to the extent such injury is not related to Hazardous
Substances conditions at the Real Property or the Adjacent Property; provided,
however, that this subparagraph (g) of Section 10.3.2 shall not be deemed to
limit Buyer's assumption and responsibility for any claims (whether arising
prior to, as of or after the Close of Escrow) as provided in this Agreement or
in any exhibit hereto related to Hazardous Substances conditions that were or
are at or from the Real Property and/or the Adjacent Property. Any
indemnification and defense to be provided pursuant to this Section 10.3.4 shall
be conducted in accordance with the procedures set forth in Section 14, below.

          10.3.5 Seller's Responsibility.  Following the Close of Escrow,
                 -----------------------
Seller shall refrain from any communications or discussions with any Agency or
any third party (other than communications or discussions relating to the
Excluded Liabilities) and from taking any other action which could result in any
Agency requesting or requiring Buyer or the owner of the Real Property, the Tar
Pits Property or any Adjacent Property to take, perform or cease any activity on
or with respect to such Real Property, the Tar Pits Property or Adjacent
Property except communications (which shall be made jointly with Buyer) relating
to remediation of the Tar Pits Property. Seller and Buyer shall give notice to
DTSC and each other Agency with which Seller has been in communications within
the past twelve (12) months regarding the Real Property, the Tar Pits Property
and/or any Adjacent Property that further communications should

                                       30
<PAGE>

be addressed to Buyer (although Seller may be copied on such notices), and shall
so refer any such communications. Seller shall deliver any and all notices and
correspondence received from any Agency to Buyer within five (5) business days
after receipt thereof. Seller acknowledges that the covenants and agreements of
Seller set forth herein are a material inducement to the agreements of Buyer set
forth herein. The provisions of this Section 10.3.5 shall be suspended during
any period in which Buyer is in Default (as hereinafter defined) or if Seller
takes action to enforce the terms of the performance and completion bond or the
IT Contract.

                    10.3.6  Indemnification by Seller. Seller agrees to
                            -------------------------
indemnify, hold harmless and defend Buyer and its members, affiliates and
subsidiaries and each of their past, current and future officers, directors,
employees, agents and representatives from and against any and all liabilities,
penalties, fines, suits, claims, demands, actions, losses, damages, expenses,
investigation and remediation costs (including, but not limited to, laboratory,
handling, transportation, containment, neutralization, disposal, capping and
other similar costs), operation and maintenance costs, financial assurance
costs, Agency costs (including, but not limited to, permitting, licensing,
hazardous waste taxes and oversight costs), causes of action, proceedings,
judgments, executions and reasonable costs of any kind or nature whatsoever
(including reasonable attorneys', consultants', engineers' and contractors'
fees) in connection with arising out of or related to any Excluded Liabilities
except for consequential damages incurred by Buyer arising out of Seller's
breach of this Agreement or any Exhibit (as distinct from consequential damages
incurred by third parties as a result of Seller's breach of this Agreement and
recovered or recoverable from Buyer which third party consequential damages
shall be recoverable hereunder). Any indemnification and defense to be provided
pursuant to this Section 10.3.6 shall be conducted in accordance with the
procedures set forth in Section 14, below.

                    10.3.7  Payment for Apollo Testing. Seller has performed
                            --------------------------
certain inspections of the Apollo Wood Recycling premises prior to the
Contingency Date. Buyer shall reimburse Seller for $20,000 of such costs upon
the Close of Escrow upon verification that not less than $40,000 was spent in
performing such inspections and preparing reports concerning same. Nothing
herein shall be deemed to excuse Apollo from any obligations it may have with
respect to the Real Property.

               10.4  IT Contract. As an inducement to execute this Agreement,
                     -----------
Seller is relying upon, and hereby approves and consents to, Buyer's retention
of ITG and LandBank, Inc., (each, a "Consultant") for the Corrective Action at
                                     ----------
or near the Real Property and/or the Tar Pits Property pursuant to a fixed-
priced contract between Buyer and ITG and a remediation services agreement with
LandBank, Inc. (the contracts, together with the lien and completion bond issued
to secure performance thereof and the multiple obligee agreement, are
collectively, the "IT Contract"), the forms of which shall be attached hereto as
                   -----------
Exhibit Q. Seller shall be an express third party beneficiary of the IT Contract
---------
and an obligee of the performance bond. Buyer shall have no obligation to obtain
Seller's consent to any termination or amendment of the IT Contract after the
Close of Escrow except for amendments relating to the Tar Pits Property. If
Buyer terminates the IT Contract or modifies it to significantly reduce the
scope of work to be performed by IT where such work is still required to be
performed by any Agency, Buyer shall, within a reasonable period of time, enter
into a contract providing for performance of the remaining Corrective Action or
the Corrective Action no longer covered by the IT Contract but still required to
be performed by any Agency. Seller shall be named as a third party beneficiary

                                       31
<PAGE>

of such contract and, if a bond is provided under such contract, Seller shall be
named as an additional obligee under such bond and be a party to a multiple
obligee agreement. Buyer shall deliver to Seller copies of any such replacement
contract and, if issued, such bond. Buyer shall also, at the request of Seller,
make a representative reasonably available to consult with Seller with respect
to such replacement contract, and, if, within a reasonable period of time prior
to the date when such replacement contract is intended to be signed, Seller
requests that such meeting be held prior to entry into the replacement contract,
Buyer shall provide Seller with a copy of the draft contract and shall make
itself reasonably available to consult with Seller prior to execution of the
replacement contract. Buyer acknowledges that it does not have any current
intention or expectation of terminating the IT Contract after the Close of
Escrow.

               10.5 Required Insurance.
                    ------------------

                    10.5.1  Upon the Close of Escrow, Buyer shall obtain the
following insurance policies in forms and with such named insureds and
additional insureds as are agreed upon by the parties prior to the expiration of
the Contingency Date (collectively, the "Insurance Policies"):
                                         ------------------

                         10.5.1.1  A Remediation Stop Loss Insurance Policy in
the form of Exhibit L;
            ---------

                         10.5.1.2  An Operations, Maintenance and Monitoring
Insurance Policy in the form of Exhibit G;
                                ---------

                         10.5.1.3  A Real Estate Environmental Liability
Insurance Policy in the form of Exhibit K.
                                ---------

                    10.5.2  Terms of Insurance.  Buyer shall pay the full policy
                            ------------------
premiums for each of the Insurance Policies and endorsements thereto at or prior
to the Close of Escrow.  Each of the Insurance Policies shall be placed through
a carrier rated A.M. Best A+,VIII or better.  Seller hereby approves the Zurich
Entities.

                    10.5.3  Deductibles.  Buyer shall be solely responsible for
                            -----------
the payment of any deductibles and self insured retentions under the Insurance
Policies.

                    10.5.4  Additional Coverage.  At its sole cost and expense,
                            -------------------
Seller may increase the liability limits under the Insurance Policies.

                    10.5.5  Amendments or Termination.  If the Zurich Entities
                            -------------------------
will not agree to prohibit termination of the Insurance Policies or amendments
which materially reduce the term, coverage or liability limits thereunder
without Seller's prior consent, Buyer agrees that it will not terminate the
Insurance Policies or enter into any amendment of the Insurance Policies which
will materially reduce the term, coverage or liability limits thereunder without
Seller's prior consent.

               10.6  Other Assumed Obligations and Liabilities. In addition to
                     -----------------------------------------
the Environmental Liabilities and Obligations, pursuant to the Omnibus
Assignment and

                                       32
<PAGE>

Assumption Agreement, Buyer shall assume and perform certain of Seller's
obligations under the Material Agreements.

               10.7  Tar Pits Property. Seller is currently seeking to amend the
                     -----------------
current remedial action plan with the DTSC for the Tar Pits Property to an
immobilization and capping remedial action plan as opposed to the current
removal and disposal. In the event Seller elects, or an Agency requires, a
removal and disposal strategy for the Tar Pits Property instead of an
immobilization and capping strategy, Seller shall pay the incremental cost of
the removal and disposal remediation alternative over the capping remediation
alternative as such costs are incurred. Seller shall have the right to elect the
removal and disposal strategy by giving written notice to Buyer at any time
prior to the commencement of the immobilization and capping of the Tar Pits
Property of its desire to cause a removal and disposal strategy for the Tar Pits
Property. Buyer shall join with Seller in seeking DTSC approval for such an
immobilization and capping remedial action plan. Buyer agrees that if a capping
plan is approved by DTSC, Buyer will use reasonable efforts to complete such
capping within eighteen (18) months after such plan is approved by DTSC or
within such shorter time period as may be required by the DTSC.

               10.8  Deed Restriction. Buyer agrees that Seller's deed to Buyer
                     ----------------
and Buyer's deed to future owners of the Real Property shall contain the
restriction set forth in Exhibit Y attached hereto.
                         ---------

               10.9  Default by Buyer. Buyer shall be deemed to have defaulted
                     ----------------
in its obligations (a "Default") and agreements set forth in Section 10.3.3.1
                       -------
hereof if all work included in the definition of Corrective Action has not been
                                                                       ---
completed on the Real Property and/or the Tar Pits Property and all of the
                                                            ---
following events occur:

                    a.  An Agency seeks in a written notice to have Seller
                    perform Corrective Action with respect to the Real Property
                    or the Tar Pits Property; and

                    b.  Seller gives Buyer written notice of the Agency's
                    written notice or order; and

                    c.  Buyer fails to respond to the Agency and timely commence
                    taking the appropriate action or entering into good faith
                    negotiations with such Agency; and

                    d.  As a result of Buyer's failure to take appropriate
                    action in response to such Agency notice, Agency performs
                    Corrective Action and submits a claim or invoice against
                    Seller for the cost of such performance; and

                    e.  Buyer does not pay the costs described in clause (d)
                    above within thirty (30) days after receipt of a demand from
                    Seller hereunder or provide a bond or other security for
                    such costs reasonably acceptable to Seller so that Seller is
                    not obligated to pay such costs to the Agency.

               Notwithstanding the foregoing, if, after the occurrence of a. and
b. above, and despite Buyer's compliance with c., above, an Agency issues an
order on Seller requiring Seller to perform Corrective Action, and the cost of
performing or failure to perform such Corrective

                                       33
<PAGE>

Action (including, without limitation, fines, penalties and/or interest for
failure to perform) will or may in the aggregate exceed $250,000 and, based on
the opinion of a "big 5" or other nationally recognized accounting firm
reasonably acceptable to Buyer, which firm is not then retained by Seller for
audit purposes, Seller will be required to disclose such order in its SEC
filings and reserve against the costs of performing or failing to perform such
order, Buyer shall be in default hereunder if Buyer has not provided such surety
or bonds as are necessary to avoid the reserve requirement of Seller on or
before the date for Seller's SEC filing in which such order shall be disclosed
and such reserve requirement will be satisfied.

          If a Default occurs as defined in this Section 10.9, then Seller shall
have the right to take such steps as necessary to cure such default (including
the right to enter onto the Real Property) and to recover from Buyer the costs
reasonably expended by Seller to cure such default. In addition, Seller shall
have the right to exercise and exercise all rights and remedies afforded to
Seller under the CDC Guaranty in a similar manner and fashion against Buyer.

          10.10  CDC Guaranty. Certain of Buyer's obligations to make payments
                 ------------
for Corrective Action shall be secured by a guaranty (the "CDC Guaranty") from
                                                           ------------
CDC in the form to be attached as of Exhibit CC hereto.  Buyer and Seller
                                     ----------
acknowledge that CDC has required that its liability under the CDC Guaranty be
subject to a cap in the amount of the self insured retention under the
Remediation Stop Loss Insurance Policy and further acknowledge that they are
discussing whether exceptions should be made to that cap, which exceptions must
be reasonably agreed upon by the parties and approved by CDC in its sole
discretion.

          -----
PROPERTY IS SOLD BY SELLER TO BUYER ON AN "AS-IS WHERE-IS" BASIS WITH NO

             Buyer's Initials               Seller's Initials

     12.  Obligations Retained by Seller. Without limiting Seller's obligations
          ------------------------------
with respect to the Excluded Liabilities in Article 10 hereof, Seller shall also
retain the following obligations following the Close of Escrow:

          12.1 Employees of Seller. Seller shall retain all obligations relating
               -------------------
to its existing or past employee relationships. Buyer shall have no obligation
to offer employment to, employ, or compensate the employees of Seller who
currently perform duties at or concerning the Real Property, and all
notifications to federal, state, or local governments concerning the effects of
the sale of the Real Property upon employees shall be the responsibility of
Seller.

          12.2 Litigation Matters.  Seller shall defend itself and the Real
               ------------------
Property and, if required, Buyer or its successors and assigns, against any
claims or causes of action raised with

                                       35
<PAGE>

respect to the SAWPA Plume, the Ontario Litigation and/or the Mushegian
Litigation, as each is more fully described in Exhibit O attached hereto. In the
                                               ---------
event that such claims or causes of action are coupled with unrelated claims or
causes of action against Buyer, then Buyer shall have the right (a) to be
represented by the same counsel as Seller and to participate in the defense of
such claims or causes of action, in which case Buyer shall pay a reasonably
prorated portion of the defense costs; or (b) to defend itself against such
unrelated claims or causes of action, in which case Buyer shall engage separate
counsel for such purpose and shall pay all costs and expenses of such separate
counsel.

     13.  Casualty and Condemnation. Casualty and condemnation occurrences prior
          -------------------------
to the Close of Escrow will have the following results:

          13.1  Casualty. If, prior to the Close of Escrow, all or any portion
                --------
of the Improvements on the Land are damaged or destroyed by an insured event,
Buyer shall purchase the Property without any reduction in the Purchase Price on
account of any diminishment of value resulting from such damage or destruction.
If, prior to the Close of Escrow, all or any portion of the Improvements on the
Land are damaged or destroyed by an uninsured event, Buyer shall have the right
(a) to purchase the Real Property without any reduction in the Purchase Price on
account of any diminishment of value resulting from such damage or destruction,
or (b) to terminate this Agreement. Buyer shall make such election by delivering
written notice to Seller within ten (10) business days after receiving written
notice of such damage or destruction. Buyer's failure to deliver notice of its
election within such ten (10) day period shall constitute Buyer's election of
alternative described in clause (b) hereof. In the event Buyer cannot or does
not terminate the Agreement pursuant to this Section 13.1, Buyer shall be
entitled at the Close of Escrow to an assignment by Seller to Buyer of Seller's
right, title and interest in and to any insurance proceeds arising out of such
damage or destruction.

          13.2 Condemnation. If, prior to the Close of Escrow, all or any
               ------------
material portion of the Real Property is taken or proposed to be taken by
eminent domain, Buyer shall have the right (a) to purchase the Real Property
which has not been condemned without any reduction in the Purchase Price on
account of any diminishment of value resulting from such taking, or (b) to
terminate this Agreement. For purposes of this Agreement, a "material" portion
of the Real Property shall be deemed to be taken or proposed to be taken if it
would cost in excess of Two Hundred Fifty Thousand Dollars ($250,000) to repair
or replace the remaining portion of the Real Property. In the event Buyer elects
not to terminate this Agreement pursuant to this Section 13.2, or in the event
that a non-material portion of the Real Property is taken or proposed to be
taken by eminent domain, then this Agreement shall remain in full force and
effect and Buyer shall be entitled at the Close of Escrow to an assignment of
any condemnation awards arising out of such taking. Prior to the Closing Date,
Buyer and Seller shall jointly prosecute, at Buyer's expense, any claim for an
award with respect to a taking of the Real Property, which claim shall not be
compromised or settled without Buyer's consent.

          13.3 Early Termination. Upon any termination of this Agreement
               -----------------
pursuant to this Article 13, Buyer shall promptly be refunded the entire Deposit
and any interest accrued thereon (less all Title Company and Escrow cancellation
fees), and the Parties shall have no other rights or obligations under this
Agreement, except that Buyer's obligations under the Entry

                                       36
<PAGE>

Permit and Buyer's and Seller's obligations under Sections 15.2, 15.9 and 15.16
of this Agreement shall survive the termination of this Agreement.

     14.  Indemnification Procedures.
          --------------------------

          14.1  Notice of Claim. With respect to any request for indemnification
                ---------------
made under this Agreement, any Exhibit hereto including, without limitation, the
Omnibus Assignment and Assumption Agreement, the Indemnitee shall give the
Indemnitor written notice thereof (together with a copy of any claim, process or
other legal pleading) promptly after becoming aware of such claim; provided,
                                                                   --------
however, that the failure of any Indemnitee to give notice as provided in this
-------
Agreement or any Exhibit hereto shall not relieve any Indemnitor of its
indemnification obligations except to the extent that such Indemnitor is
actually prejudiced by such failure to give notice. Such notice shall describe
such claim in reasonable detail. Nothing in this Section 14.1 shall be deemed to
prevent a Party from making a claim under any available insurance policy, in
addition to pursuing indemnifications under this Agreement or any Exhibit
hereto.

          14.2  Defense of Claim.  An Indemnitor, at such Indemnitor's own
                ----------------
expense and through counsel chosen by such Indemnitor (which counsel shall be
reasonably acceptable to the Indemnitee), may, but shall have no obligation to,
elect to defend any claim.  If an Indemnitor elects to defend a claim, then,
within ten (10) business days after receiving notice of such claim (or sooner,
if the nature of such claim so requires), such Indemnitor shall notify the
Indemnitee of its intent to do so, and such Indemnitee shall cooperate in the
defense of such claim (and pending such notice and assumption of defense, an
Indemnitee may take such steps to defend against such claim as, in such
Indemnitee's good faith judgment, are appropriate to protect its interests).
Such Indemnitor shall pay such Indemnitee's reasonable out-of-pocket expenses
incurred in connection with such cooperation.  Such Indemnitor shall keep the
Indemnitee reasonably informed as to the status of the defense of such claim.
After notice from an Indemnitor to an Indemnitee of its election to assume the
defense of a claim, such Indemnitor shall not be liable to such Indemnitee for
any legal or other expenses subsequently incurred by such Indemnitee in
connection with the defense thereof other than those expenses referred to in the
preceding sentence; provided, however, that such Indemnitee shall have the right
                    --------  -------
to employ one law firm as counsel, together with a separate local law firm in
each applicable jurisdiction (if necessary) ("Separate Counsel"), to represent
                                              ----------------
such Indemnitee in any action or group of related actions (which firm or firms
shall be reasonably acceptable to the Indemnitor) if, in such Indemnitee's
reasonable judgment at any time, either a conflict of interest between such
Indemnitee and such Indemnitor exists in respect of such claim, or there may be
defenses available to such Indemnitee which are different from or in addition to
those available to such Indemnitor and the representation of both parties by the
same counsel would be inappropriate, and in that event:  (a) the reasonable fees
and expenses of such Separate Counsel shall be paid by such Indemnitor (it being
understood, however, that the Indemnitor shall not be liable for the expenses of
more than one Separate Counsel (excluding local counsel) with respect to any
claim (even if against multiple Indemnitees)); and (b) each of such Indemnitor
and such Indemnitee shall have the right to conduct its own defense in respect
of such claim.  If any Indemnitor elects not to defend against a claim, or fails
to notify an Indemnitee of its election as provided in this Section 14.2 within
the period of ten (10) business days described above, the Indemnitee may defend,
compromise and settle such claim and shall be entitled to indemnification
hereunder (to

                                       37
<PAGE>

the extent permitted by this Agreement). Notwithstanding the foregoing, the
Indemnitor shall not, without the prior written consent of the Indemnitee (which
consent shall not be unreasonably withheld, conditioned or delayed), settle or
compromise any claim or consent to the entry of any judgment unless (x) there is
no finding or admission of any violation of law or any violation of the rights
of any person and no effect on any other claims that may be made against the
Indemnitee and (y) the sole relief provided is monetary damages that are paid in
full by the Indemnitor.

     15.  Miscellaneous.
          -------------

          15.1  Entire Agreement; Modification. This Agreement constitutes the
                ------------------------------
entire Agreement between the Parties hereto pertaining to the subject matter
hereof and supersedes all prior negotiations, agreements and understandings of
the Parties with respect to the subject matter hereof. All exhibits referred to
in this Agreement are attached and incorporated by this reference. This
Agreement may not be amended or otherwise changed except by a writing executed
by both Parties.

          15.2  Confidentiality.  Until the Close of Escrow, Buyer agrees that
                ---------------
the terms and conditions of this Agreement and any information concerning the
Property obtained either from Seller or through other third parties shall be
used solely for the purpose of evaluating the Property. Unless and until Buyer
has completed the acquisition of the Real Property, such information shall be
kept confidential by Buyer and its advisors, except as necessary to develop,
sell and finance the Real Property and to perform its obligations pursuant to
this Agreement or as required by the rules of Securities Exchange Commission.
Seller understands that Buyer may need to disclose the such information or
portions thereof to those of Buyer's directors, officers, employees, agents,
advisors, attorneys, accountants, consultants, lenders, investment bankers,
investment partners and financial advisors (collectively, "Representatives") who
                                                           ---------------
need to know such information for the purpose of evaluating or financing Buyer's
acquisition of the Property or in connection with obtaining the Insurance
Policies, and also to developers in connection with Buyer's evaluation of the
feasibility of Buyer's proposed development of the Real Property. Prior to any
such disclosure, however, Buyer shall inform such Representatives and developers
of the confidential nature of such information, and such Representatives of
Buyer and developers shall agree to be bound by this statement of
confidentiality and not to disclose such information to any other person. Buyer
has also agreed to be responsible for any breach of this statement of
confidentiality by Buyer or its Representatives. In the event that Buyer or any
of its Representatives become legally compelled to disclose any of such
information, Buyer and its Representatives shall provide Seller with prompt
prior written notice of such requirements so that Seller may seek a protective
order or other appropriate remedy and/or waive compliance with the terms of this
statement of confidentiality. In the event that Buyer fails to complete the
acquisition of the Property, Buyer and its Representatives will promptly return
to Seller all of such written information which has been provided to Buyer and
its Representatives will destroy all copies of any analysis, compilations,
studies or other documents prepared by Buyer or for its use containing or
reflecting any such information. Buyer acknowledges that Seller is a publicly
traded company and is required to publicly disclose certain material
information.

          15.3  Further Assurances. Each Party hereto shall from and after the
                ------------------
date hereof execute and acknowledge and deliver such further instruments and
perform such additional acts

                                       38
<PAGE>

as any other Party may reasonably request to effectuate the intent of this
Agreement; provided, however, that no such request may require any Party to make
           --------  -------
any material expenditure.


          15.4  Notices. Any notices, demands or other communications required
                -------

may desire to give the other shall be given in writing, delivered personally or
sent by certified mail, postage pre-paid, facsimile, or by Federal Express or
similar generally recognized delivery service regularly providing proof of

     Chicago Title Company
     560 East Hospitality Lane
     San Bernardino, CA 92408
     Attn.: Kathy Benson
     Telephone: (909) 884-0448
     Telecopier: (909) 384-7855

          A copy of any notice, demand or other communication given to or by
Escrow Holder by or to either Party shall be given to the other Party at the
same time. Notice by United States Postal Service or delivery service as
provided herein shall be considered given on the earlier of the date on which
said notice is actually received by the Party to whom such notice is addressed,
or as of the date of delivery, whether accepted or refused, established by the
United States Postal service return receipt or such overnight carrier's proof of
delivery, as the case may be. Any such notice given by facsimile shall be deemed
given upon receipt of the same by the Party to which it is addressed, provided
that such facsimile was received between the hours of 8:00 a.m. and 5:00 p.m.
local time of the recipient of the facsimile on a business day. Receipt of a
facsimile at any other time will be deemed received on the next business day.

          15.5  Computation of Time. All references to a period of "days" shall
                -------------------
mean calendar days unless otherwise specifically set forth herein. If the last
day for any period or any date pursuant to this Agreement is a weekend or
holiday, such last day or date shall automatically be deemed to be the next
succeeding business day. A day shall be construed to be a business day if banks
are open for business on that day in the county in which the Real Property is
located.

          15.6  Counterparts. This Agreement may be executed in one or more
                ------------
counterparts, and bear the signature of each Party on a separate counterpart,
each of which when so executed and delivered shall be deemed an original but all
of which taken together shall constitute but one and the same instrument.

          15.7  Time of the Essence.  Seller and Buyer hereby acknowledge and
                -------------------
agree that time is strictly of the essence with respect to each and every term,
condition, obligation and provision hereof and that failure to timely perform
any of the terms, conditions, obligations or provisions hereof by either Party
shall constitute a material breach of and a non-curable (but waivable) default
under this Agreement by the Party so failing to perform.

          15.8  Binding Effect; Assignment. This Agreement shall be binding upon
                --------------------------
and inure to the benefit of Seller and Buyer and their respective successors and
permitted assigns.  Buyer may assign its rights and obligations under this
Agreement with Seller's prior written consent, which shall not be unreasonably
withheld.  No assignment of any rights or obligations hereunder shall be deemed
to release any party hereto from its obligations hereunder unless the non-
assigning party expressly agrees to such release.

          15.9  Enforcement Costs.  Should either Party institute any action or
                -----------------
proceeding to enforce any provision of this Agreement, or for damages by reason
of an alleged breach of any

                                       40
<PAGE>

provision of this Agreement, or for a declaration of rights hereunder, the
prevailing Party in such action, on trial or appeal, shall be entitled to
receive from the other Party all costs and expenses of such action or
proceeding, including reasonable attorneys', consultants', experts' and
engineers' fees incurred by the prevailing Party in connection with such action
or proceeding. Such costs and expenses shall include, without limitation,
attorneys', consultants' and engineers' fees, costs and expenses incurred in
trial, on appeal and in post-judgment motions, garnishment, levy and debtor and
third party examinations, discovery, and bankruptcy proceedings.

          15.10  Waivers. No Party shall be deemed to have waived any right
                 -------
which such Party has under this Agreement, unless this Agreement expressly
provides a period of time within which such right may be exercised and such
period has expired, or unless such Party has expressly waived the same in
writing or unless this Agreement specifies that a waiver shall be deemed to have
occurred. Except as otherwise provided herein, the waiver by either Party of a
right, claim or default by the other Party hereunder shall not be deemed to be a
waiver of any other right, claim or default, or any subsequent default of the
same kind. No waiver of a condition shall limit either Party's liability for a
breach of this Agreement.

          15.11  No Third Party Beneficiary. Except as otherwise expressly set
                 --------------------------
forth herein, no term or provision of this Agreement or the exhibits hereto is
intended to or shall be for the benefit of any person or entity not a party
hereto, and no such other person or entity shall have any right or cause of
action hereunder, nor is anything in this Agreement intended to relieve or
discharge the obligation or liability of any third persons to any Party to this
Agreement.

          15.12  Governing Law.  The Parties hereto expressly agree that this
                 -------------
Agreement shall be governed by, interpreted under, and construed and enforced in
accordance with the laws of the State of California without the application of
its choice of law rules.

          15.13  Construction.  Headings at the beginning of each paragraph and
                 ------------
subparagraph are solely for the convenience of the Parties and are not a part of
the Agreement.  Whenever required by the context of this Agreement, the singular
shall include the plural and the masculine shall include the feminine and vice
versa.  This Agreement shall not be construed as if it had been prepared by one
of the Parties, but rather as if both Parties had prepared the same.  Unless
otherwise indicated, all references to paragraphs and subparagraphs are to this
Agreement.  All exhibits referred to in this Agreement are attached and
incorporated by this reference.  In the event the date on which Buyer or Seller
is required to take any action under the terms of this Agreement is not a
business day, the action shall be taken on the next succeeding business day.

          15.14  Partial Invalidity.  If any term or provision of this Agreement
                 ------------------
or the application thereof to any person or circumstance shall, to any extent,
be invalid or unenforceable, the remainder of this Agreement, or the application
of such term or provision to persons or circumstances other than those as to
which it is held invalid or unenforceable, shall not be affected thereby, and
each such term and provision of this Agreement shall be valid and be enforced to
the fullest extent permitted by Law.

          15.15  Cumulative Remedies.  No remedy conferred upon a Party in this
                 -------------------
Agreement is intended to be exclusive of any other remedy herein or by law
provided or

                                       41
<PAGE>

permitted, but each shall be cumulative and shall be in addition to every other
remedy given hereunder or now or hereafter existing at law, in equity or by
statute (except as otherwise expressly herein provided).

          15.16  Indemnity.  Buyer shall indemnify, defend and hold Seller
                 ---------
harmless from and against any losses, damages, costs and expenses (including,
but not limited to, attorneys' fees and costs) incurred by Seller by reason of
any breach or inaccuracy of Buyer's representations set forth in Section 8.3.
Seller shall indemnify, defend and hold Buyer harmless from and against any
losses, damages, costs and expenses (including, but not limited to, attorneys'
fees and costs) incurred by Buyer by reason of any breach or inaccuracy of
Seller's representations set forth in Section 7.4 or as a result of any
commission claimed as a result of Seller's acts by EYKL for any matter or by any
other broker described in Exhibit T attached hereto for matters other than those
described in Exhibit T.  The provisions of this Section 15.16 shall survive the
Close of Escrow and the recordation of the Deed for a period of thirty-six (36)
months, and any action under this Section 15.16 must be filed and served within
thirty-nine (39) months from the date of recordation of the Deed.

          15.17  Pre-Closing Conveyance.  Prior to the Close of Escrow, Kaiser
                 ----------------------
Steel Land Development shall be entitled to convey its interest in the Real
Property by grant deed to Kaiser Ventures, Inc. in which event the Grant Deed
required hereunder shall be delivered solely by Kaiser Ventures, Inc.
