                              STOCK PURCHASE AGREEMENT



     THIS STOCK PURCHASE AGREEMENT ("AGREEMENT") is entered into as of this 30th
day of March, 1998 between and among Koll Real Estate Group, Inc., a Delaware
corporation ("KREG"), KREG Holdings Inc., a Delaware corporation which is a
wholly -owned subsidiary of KREG ("KHI"), KN Holding Corp., a New York
corporation ("KNHC"), Koll Development Company LLC, a Delaware limited liability
company ("KDC"), and, solely for purposes of SECTION 10.1, Donald M. Koll and
Richard M. Ortwein (collectively , the "INDIVIDUAL PARTIES") and solely for the
purpose of SECTION 4.1, Donald M. Koll.  Capitalized terms not otherwise defined
when first used herein shall have the meaning assigned to them in ARTICLE  XII
of this Agreement.


                                  R E C I T A L S

     WHEREAS, KHI owns all  1,000 shares of Common Stock (the "STOCK") of KREG
Operating Co., a Delaware corporation ("KOC");

     WHEREAS, KREG desires to cause KHI to sell to  KNHC, and  KNHC desires to
purchase from KHI, the Stock; and

     WHEREAS, KNHC desires to cause KOC to be liquidated and its assets and
liabilities to be contributed to KDC (such liquidation and contribution,
collectively, the "Contribution"); following which KNHC shall be relieved of any
further obligation under this Agreement, provided that all of its assets and
obligations hereunder have been transferred to and assumed by KDC, pursuant to
the Contribution, to the same extent as if KDC had originally purchased the
Stock pursuant to this Agreement.

                                 A G R E E M E N T

     NOW, THEREFORE, in consideration of the preceding recitals and the
representations, warranties, covenants and agreements set forth herein, and
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto agree as follows:


                           I.  SALE AND PURCHASE OF STOCK

     1.1   AGREEMENT TO SELL AND PURCHASE STOCK.  For the consideration
hereinafter provided and subject to the terms and conditions of this Agreement,
at the Closing (as defined in SECTION 1.3), KHI shall sell, assign, transfer,
convey and deliver to  KNHC, free and clear of all liens, charges, claims or
encumbrances, and  KNHC shall purchase and acquire from KHI, the Stock.  At the
Closing, KHI shall cause to be delivered to  KNHC


                                          1
<PAGE>

a certificate representing the Stock, together with an accompanying signed stock
power or instrument of assignment, duly endorsed in blank for the transfer of
the Stock to  KNHC.

     1.2   PURCHASE PRICE.  Subject to the terms and conditions of this
Agreement and in addition to the other deliverables of  KNHC as set forth in
SECTION 8.2, KNHC agrees to pay to KHI the collective purchase price (the
"PURCHASE PRICE") for the Stock as follows:

           (a)  $1 million of the Purchase Price shall be delivered to KHI in
     immediately available funds upon the execution of this Agreement (the
     "INITIAL CONSIDERATION"), which shall not be subject to return to  KNHC
     except to the extent provided for in accordance with the provisions of
     SECTION 4.1 or SECTION 11.15;

           (b) $29 million of the Purchase Price shall be delivered to KHI in
     immediately available funds at the Closing (the "CLOSING CONSIDERATION");
     and

           (c)  such additional amount shall be delivered to KHI in immediately
     available funds at the Closing as is determined no later than one (1) day
     prior to the Closing in accordance with the  methodology set forth on
     SCHEDULE  1.2 (the "1998 ACTIVITY CONSIDERATION").  As a clarification to
     the methodology set forth on SCHEDULE 1.2, it is the intention of the
     parties hereto that all 1998 revenue through and including the Closing Date
     received by KOC shall decrease the Purchase Price and all 1998 expenses
     through, and including the Closing Date paid by KOC shall increase the
     Purchase Price.  The dollar amounts set forth on SCHEDULE  1.2  are based
     upon reasonably available information as of the date of this Agreement,
     however, such amounts shall be updated on the basis of the best available
     information prior to the Closing and the amount of the  1998 Activity
     Consideration shall then be recalculated for the purpose of determining the
     amount to be paid on the Closing Date.  Within thirty (30) days after the
     Closing Date, a final accounting of KOC's consolidated financial activity
     from January 1, 1998 through the Closing Date shall be completed and
     reviewed by the accounting staffs of KDC and KREG.  Thereafter, the amount
     of the  1998 Activity Consideration shall be calculated for the final time
     and (i) if the amount paid on the Closing Date is determined to be less
     than the amount of the final calculation then  KNHC shall pay the
     incremental amount to KREG in immediately available funds within five (5)
     days of such determination, or (ii) if the amount paid on the Closing Date
     is determined to be more than the amount of the final calculation then KREG
     shall repay the incremental amount to  KNHC in immediately available funds
     within five (5) days of such determination.

     The amount of all cash balances in the various bank accounts of KOC and the
Investments, as reflected on the books and records of KOC and the Investments,
but subject to adjustment for month-end bank account reconciliations to the book
balance, shall be delivered to KREG on the Closing Date as a partial repayment
of intercompany debt owed to KREG by KOC and its Affiliates.  Following the
final calculation and payment in full of the 1998 Activity Consideration, the
balance of the amount of intercompany debt of


                                          2
<PAGE>

KOC and the Investments that is reflected as being outstanding on the books of
KREG shall be deemed a capital contribution made as of the Closing Date.

     1.3   CLOSING.  The closing of the sale and purchase of the Stock under and
in accordance with this Agreement (the "CLOSING") shall take place at the
offices of McDermott, Will & Emery, 1301 Dove Street, Suite 500, Newport Beach,
California, on (a) April 30, 1998, (b) such later date determined in accordance
with the provisions of SECTION 4.1, (c) such later date determined by KNHC
pursuant to the proviso in SECTION 7.4, or (d) such earlier or later date as may
be mutually agreed to in writing by the parties hereto (the "CLOSING DATE").


                  II. REPRESENTATIONS AND WARRANTIES OF KREG AND KHI

     As an inducement to KNHC and KDC to enter into this Agreement and to
purchase the Stock, KREG and KHI jointly and severally represent and warrant to
KNHC and KDC as set forth below in this ARTICLE II; provided, however, that no
such representation or warranty which is qualified as being subject to the
Knowledge of the Individual Parties shall be deemed to have been made in the
event that such representation or warranty was not, to the Knowledge of the
Individual Parties, true and correct at the time(s) made:

     2.1   CAPITALIZATION; OWNERSHIP OF KOC SHARES.   The authorized capital
stock of KOC consists of the Stock, all of which shares are issued and
outstanding and owned beneficially and of record by KHI.  Subject to the
Knowledge of the Individual Parties, there are no securities convertible into or
exchangeable or exercisable for shares of capital stock of KOC and no warrants,
calls, options or other rights to acquire from KOC or KHI, or any obligation of
KOC or KHI  to issue, any securities of KOC.

     2.2   SUBSIDIARIES AND OTHER INVESTMENTS.  SCHEDULE 2.2  identifies KOC's
equity or other interests in all of its direct and indirect subsidiaries and the
KOC Employee Affiliates (collectively, the "INVESTMENTS") as of the date of this
Agreement, but no representation or warranty is made as to any of the assets
held by any of the KOC Employee Affiliates or Project Partnerships, including
any of their respective equity or other interests in any other entity, joint
venture or project.  All the outstanding shares of capital stock of, or other
equity interests in, each Investment are: duly authorized, validly issued, fully
paid and nonassessable and not subject to preemptive rights; are (subject to the
Knowledge of the Individual Parties) owned directly or indirectly by KOC free
and clear of all pledges, claims, liens, charges, encumbrances and security
interests securing indebtedness or similar obligations (collectively "Liens");
and are (subject to the Knowledge of the Individual Parties) free of any other
restriction on the right to vote, sell or otherwise dispose of such capital
stock or other ownership interests that would prevent the operation by KOC of
such Investment's business as currently conducted, provided that although the
partnership agreements of each KOC Employee Affiliate do not contain any
restrictions on transfer, the organizational documents of certain Project
Partnerships may contain restrictions on transfer of KOC's interests in the KOC
Employee Affiliates.  Other than as


                                          3
<PAGE>

set forth on SCHEDULE 2.2, there are no securities convertible into or
exchangeable or exercisable for shares of capital stock of, or other interests
in, any Investment and (subject to the Knowledge of the Individual Parties) no
warrants, calls, options or other rights to acquire from KOC or any Investment,
or (subject to the Knowledge of the Individual Parties) any obligation of KOC or
any Investment to issue, any securities of any Investment.  There are no
agreements, commitments, understandings, arrangements, facts or circumstances
which create or would give rise to the creation of any direct, contingent or
other economic or beneficial interest being held by KREG or KHI or their
respective lower tier Affiliates after the Closing which relates directly or
indirectly to any of the Investments or their assets including, without
limitation, the Project Partnerships (collectively the "Interests") and to the
extent any such Interests exist, KREG disclaims any legal or beneficial interest
in the Project Partnerships and agrees that if it receives any proceeds with
respect thereto to promptly remit such proceeds to KDC.

     2.3   ORGANIZATION AND GOOD STANDING.  Each of KREG, KHI, KOC and each
Investment is a corporation, or limited partnership duly organized, validly
existing and in good standing under the laws of the state of its organization
and has the requisite corporate or other power and authority to carry on its
business as now conducted.  KOC and each Investment is duly qualified or
licensed to do business and is in good standing (with respect to jurisdictions
which recognize such concept) in (subject to the Knowledge of the Individual
Parties) each jurisdiction in which the nature of its business or the ownership,
leasing or operation of its properties makes such qualification or licensing
necessary except where the failure to be qualified or licensed would not have a
Material Adverse Effect.  KREG has made available to KNHC prior to the execution
of this Agreement complete and correct copies of the certificate of
incorporation and by-laws of KOC and the certificates of incorporation, by-laws,
partnership agreements, or similar organizational documents of each Investment,
in each case as amended to date.

     2.4   AUTHORIZATION AND VALIDITY.  KREG and KHI have all requisite
corporate power to enter into this Agreement and all other agreements entered
into in connection with the transactions contemplated hereby and to consummate
the transactions contemplated hereby and thereby.  The execution, delivery and

     2.7   EMPLOYEE BENEFIT PLANS; ERISA

     (a)   SCHEDULE 2.7A contains a true and complete list (subject to the
Knowledge of the Individual Parties) of each material bonus, incentive
compensation, severance, change-in-control, or termination pay, profit-sharing,
pension, or retirement plan, program, agreement or arrangement and each other
material employee benefit plan, program, agreement or arrangement, sponsored,
maintained or contributed to or required to be contributed to by KOC or any of
its subsidiary corporations or KREG or any subsidiary corporations of KREG, all
of which are set forth in SCHEDULE 2.7B (an "ERISA AFFILIATE"), that together
with KOC would be deemed a "single employer" within the meaning of SECTION
4001(b)(1) of ERISA, for the benefit of any current or former employee or
director of KOC, or any ERISA Affiliate (the "PLANS").  Included in SCHEDULE
2.7A are the Plans that are "employee welfare benefit plans," or "employee
pension benefit plans" as such terms are defined in Sections 3(1) and 3(2) of
ERISA (such plans being hereinafter referred to collectively as the "ERISA
PLANS").  None of KOC nor any ERISA Affiliate has (subject to the Knowledge of
the Individual Parties) any formal plan or commitment, whether legally binding
or not, to create any additional Plan or modify or change any existing Plan that
would affect any current or former employee or director of KOC or any ERISA
Affiliate.

     (b)   With respect to each of the Plans, KREG or KOC has heretofore made
available to KNHC true and complete copies of (i) each of the Plan documents
(including all amendments thereto) for each written Plan or a written
description of any Plan that is not otherwise in writing, (ii) if the Plan is
funded through a trust or any other funding vehicle, a copy of the trust or
other funding agreement (including all amendments thereto) and the latest
financial statements thereof, if any, and (iii) the most recent determination
letter received from the IRS with respect to each Plan that is intended to be
qualified under section 401(a) of the Internal Revenue Code of 1986, as amended
(the "CODE").

     (c)   No liability under Title IV of ERISA has been incurred by KOC or any
ERISA Affiliate (except for the Pullman Inc. Non-contributory Pension Plan which
is the responsibility of MAFCO Consolidated Group, Inc., and the current status
of which KREG is not aware) that has not been satisfied in full, and no
condition exists that presents a material risk to KOC or any ERISA Affiliate of
incurring any liability under such Title, other than liability for premiums due
the Pension Benefit Guaranty Corporation (the "PBGC"), which payments have been
or will be made when due.  To the extent this representation applies to Sections
4064, 4069 or 4204 of Title IV of ERISA, it is made not only with respect to the
ERISA Plans but also with respect to any employee benefit plan, program,
agreement or arrangement subject to Title IV of ERISA to which KOC or any ERISA
Affiliate made, or was required to make, contributions during the past six
years.


                                          6
<PAGE>

     (d)   The PBGC has not instituted proceedings pursuant to Section 4042
of ERISA to terminate any of the ERISA Plans subject to Title IV of ERISA,
and no condition exists that presents a material risk that such proceedings
will be instituted by the PBGC.

     (e)   With respect to each of the ERISA Plans that is subject to Title
IV of ERISA, the present value of accumulated benefit obligations under such
Plan, as determined by the Plan's actuary based upon the actuarial
assumptions used for funding purposes in the most recent actuarial report
prepared by such Plan's actuary with respect to such Plan, did not, as of its
latest valuation date, exceed the then current value of the assets of such
Plan allocable to such accumulated benefit obligations (excluding the Pullman
Inc. Non-contributory Pension Plan which is the responsibility of MAFCO
Consolidated Group, Inc., and the current status of which KREG is not aware).

     (f)   None of KOC, any ERISA Affiliate, any of the ERISA Plans, any
trust created thereunder, nor to the Knowledge of KREG, any trustee or
administrator thereof has engaged in a transaction or has taken or failed to
take any action in connection with which KOC or any ERISA Affiliate could be
subject to any material liability for either a civil penalty assessed
pursuant to Section 409 or 502(i) of ERISA or a tax imposed pursuant to
section 4975(a) or (b), 4976 or 4980B of the Code.

     (g)   All contributions and premiums which KOC or any ERISA Affiliate is
required to pay under the terms of each of the ERISA Plans and section 412 of
the Code, have, to the extent due, been paid in full or properly recorded on
the financial statements or records of KOC and none of the ERISA Plans or any
trust established thereunder has incurred any "accumulated funding
deficiency" (as defined in Section 302 of ERISA and section 412 of the Code),
whether or not waived, as of the last day of the most recent fiscal year of
each of the ERISA Plans ended prior to the date of this Agreement.  No lien
has been imposed under section 412(n) of the Code or Section 302(f) of ERISA
on the assets of KOC or any ERISA Affiliate, and no event or circumstance has
occurred that is reasonably likely to result in the imposition of any such
lien on any such assets on account of any ERISA Plan.

     (h)   No ERISA Plan is a "multiemployer plan," as such term is defined
in Section 3(37) of ERISA.

     (i)   Each of the Plans has been operated and administered in all
material respects in accordance with applicable laws, including but not
limited to ERISA and the Code.

     (j)   With regard to each of the ERISA Plans that is intended to be
"qualified" within the meaning of Section 401(a) of the Code, the sponsor of
the Plan has applied for a currently effective determination letter from the
IRS stating that it is so qualified, and to the Knowledge of KREG, no event
has occurred which would affect such qualified status except for a recent
amendment to The Koll Company 401(k) Plan.

                                          7
<PAGE>

     (k)   Any fund established under an ERISA Plan that is intended to
satisfy the requirements of section 501(c)(9) of the Code has received an IRS
letter confirming satisfaction of such requirements, and no event has
occurred which, to the Knowledge of KREG, would affect such satisfaction.

     (l)   No amounts payable under any of the Plans or any other contract,
agreement or arrangement with respect to which KOC or any ERISA Affiliate may
have any liability could fail to be deductible for federal income tax
purposes by virtue of section 162(m) or section 280G of the Code.

     (m)   Except for the KREG Retiree Medical Plan, no Plan provides
benefits, including without limitation death or medical benefits (whether or
not insured), with respect to current or former employees of KOC or any ERISA
Affiliate after retirement or other termination of service (other than (i)
coverage mandated by applicable laws, (ii) death benefits or retirement
benefits under any "employee pension plan," as that term is defined in
Section 3(2) of ERISA, (iii) deferred compensation benefits accrued as
liabilities on the books of KOC or an ERISA Affiliate, or (iv) benefits, the
full direct cost of which is borne by the current or former employee (or
beneficiary thereof)).

     (n)   The consummation of the transactions contemplated by this
Agreement (including the Contribution) will not, either alone or in
combination with any other event, (i) entitle any current or former employee,
officer or director of KOC or any ERISA Affiliate except for employees
remaining with KREG after the Closing Date to continued participation in any
ERISA Plan, to severance pay, unemployment compensation or any other similar
termination payment, or (ii) accelerate the time of payment or vesting, or
increase the amount of or otherwise enhance any benefit due any such
employee, officer or director.

SECTION 1504 of the Code of which KOC is or has been a member (the "KREG
CONSOLIDATED GROUP"), has filed or caused to be filed in a timely manner (within

this SECTION 2.8 and SECTIONS 9.4, 9.5, 11.23, 11.24 and 11.25, references to
KOC shall include KOC and any Person in which KOC has a direct or indirect
ownership interest.

shall be deemed an additional contribution of capital and all such agreements,
arrangements and understandings shall be terminated as of the Closing Date
without any further liability.

arbitral or other proceedings, or, as to which KREG has received written notice,
any claims, actions, causes of action, private environmental investigations or

     warranty that was breached) or covenant of KNHC or KDC contained in this
     Agreement or in any schedule, exhibit, certificate or other instrument

          (c)  any acts or omissions of KOC or its Affiliates that result in any
     action being threatened or pursued against KREG or any of its Affiliates
     pursuant to any of the Guarantees.

          (a)  any party claiming indemnification pursuant to this ARTICLE  IX
     (an "INDEMNIFIED PARTY") shall promptly (and, in any event at least ten
     days prior to the due date for any responsive pleadings, filings or other
     documents) (i) notify the party for whom indemnification is sought (the
     "INDEMNIFYING PARTY") of any third -party claim or claims asserted against
     the Indemnified Party (a "THIRD PARTY CLAIM")  that could give rise to a
     right of indemnification pursuant to this ARTICLE  IX and (ii) transmit to
     the Indemnifying Party a written notice ("CLAIM NOTICE") describing in
     reasonable detail the nature of the Third Party Claim, a copy of all papers
     served with respect to such claim (if any), an estimate of the amount of
     Damages attributable to the Third Party Claim and the basis of the
     Indemnified Party's request for indemnification under this Agreement.  The
     failure to promptly deliver a Claim Notice shall not relieve any
     Indemnifying Party of its obligations to any


                                          22
<PAGE>

     Indemnified Party with respect to the related Third Party Claim except to
     the extent that the resulting delay is materially prejudicial to the
     defense of such claim.  Within 30 days after receipt of any Claim Notice
     (the "ELECTION PERIOD"), the Indemnifying Party shall notify the
     Indemnified Party (x) whether the Indemnifying Party disputes its potential
     liability to the Indemnified Party under this ARTICLE  IX with respect to
     such Third Party Claim and (y) whether the Indemnifying Party desires, at
     the sole cost and expense of such Indemnifying Party, to defend the
     Indemnified Party against such Third Party Claim;

          (b)  If the Indemnifying Party notifies the Indemnified Party within
     the Election Period that the Indemnifying Party elects to assume the
     defense of the Third Party Claim, then the Indemnifying Party shall have
     the right to defend, at its sole cost and expense, with counsel reasonably
     acceptable to such Indemnified Party, such Third Party Claim by all
     appropriate proceedings, which proceedings shall be prosecuted diligently
     by the Indemnifying Party to a final conclusion or settled at the
     discretion of the Indemnifying Party in accordance with this SECTION
     9.3(b).  Except as set forth in SECTION 9.3(f) hereof, the Indemnifying
     Party shall have full control of such defense and proceedings, including
     any compromise or settlement thereof.  The Indemnified Party is hereby
     authorized, at the sole cost and expense of the Indemnifying Party (but
     only if the Indemnified Party is entitled to indemnification hereunder), to
     file, during the Election Period, any motion, answer or other pleadings
     that the Indemnified Party shall deem necessary or appropriate to protect
     its interests or those of the Indemnifying Party and not prejudicial to the
     Indemnifying Party.  If requested by the Indemnifying Party, the
     Indemnified Party agrees, at the sole cost and expense of the Indemnifying
     Party, to cooperate with the Indemnifying Party and their counsel in
     contesting any Third Party Claim that the Indemnifying Party elects to
     contest, including, without limitation, the making of any related
     counterclaim against the Person asserting the Third Party Claim or any
     cross -complaint against any Person.  The Indemnified Party may participate
     in, but not control, any defense or settlement of any Third Party Claim
     controlled by the Indemnifying Party pursuant to this SECTION 9.3(b) and
     shall bear its own costs and expenses with respect to such participation;
     provided, however, that if the named parties to any such action (including
     any impleaded parties) include both the Indemnifying Party and the
     Indemnified Party, and the Indemnified Party has been advised by counsel
     that there may be one or more legal defenses available to it that are
     different from or additional to those available to the Indemnifying Party,
     then the Indemnified Party may employ separate counsel at the expense of
     the Indemnifying Party, and upon written notification thereof, the
     Indemnifying Party shall not have the right to assume the defense of such
     action on behalf of the Indemnified Party; provided further that the
     Indemnifying Party shall not, in connection with any one such action or
     separate but substantially similar or related actions in the same
     jurisdiction arising out of the same general allegations or circumstances,
     be liable for the reasonable fees and expenses of more than one separate
     firm of attorneys at any time for the Indemnified Party, which firm shall
     be designated in writing by the Indemnified Party.  Notwithstanding the
     foregoing, the Indemnifying Party shall be prohibited from


                                          23
<PAGE>

     confessing or settling any criminal allegations brought against the
     Indemnified Party without the express written consent of the Indemnified
     Party.

          (c)  If the Indemnifying Party fails to notify the Indemnified Party
     within the Election Period that the Indemnifying Party elects to defend the
     Indemnified Party pursuant to SECTION 9.3(b), or if the Indemnifying Party
     elects to defend the Indemnified Party pursuant to SECTION 9.3(b) but fails
     diligently and promptly to prosecute or settle the Third Party Claim, then
     the Indemnified Party shall have the right to defend, at the sole cost and
     expense of the Indemnifying Party (if the Indemnified Party is entitled to
     indemnification hereunder), the Third Party Claim by all appropriate
     proceedings, which proceedings shall be promptly and vigorously prosecuted
     by the Indemnified Party to a final conclusion or settled.  The Indemnified
     Party shall have full control of such defense and proceedings, provided,
     however, that the Indemnified Party may not enter into, without the
     Indemnifying Party's consent, which shall not be unreasonably withheld, any
     compromise or settlement of such Third Party Claim.  Notwithstanding the
     foregoing, if the Indemnifying Party has delivered a written notice to the
     Indemnified Party to the effect that the Indemnifying Party disputes their
     potential liability to the Indemnified Party under this ARTICLE  IX and if
     such dispute is resolved in favor of the Indemnifying Party, the
     Indemnifying Party shall not be required to bear the costs and expenses of
     the Indemnified Party's defense pursuant to this SECTION 9.3 or of the
     Indemnifying Party's participation therein at the Indemnified Party's
     request, and the Indemnified Party shall reimburse the Indemnifying Party
     in full for all reasonable costs and expenses of such litigation.  The
     Indemnifying Party may participate in, but not control, any defense or
     settlement controlled by the Indemnified Party pursuant to this SECTION
     9.3(c), and the Indemnifying Party shall bear its own costs and expenses
     with respect to such participation; provided, however, that if the named
     parties to any such action (including any impleaded parties) include both
     the Indemnifying Party and the Indemnified Party, and the Indemnifying
     Party has been advised by counsel that there may be one or more legal
     defenses available to it that are different from or additional to those
     available to the Indemnified Party, then the Indemnifying Party may employ
     separate counsel and upon written notification thereof, the Indemnified
     Party shall not have the right to assume the defense of such action on
     behalf of the Indemnifying Party.

          (d)  In the event any Indemnified Party should have a claim against
     any Indemnifying Party hereunder that does not involve a Third Party Claim,
     the Indemnified Party shall transmit to the Indemnifying Party a written
     notice (the "INDEMNITY NOTICE") describing in reasonable detail the nature
     of the claim, an estimate of the amount of damages attributable to such
     claim and the basis of the Indemnified Party's request for indemnification
     under this Agreement.  If the Indemnifying Party does not notify the
     Indemnified Party within thirty (30) days from its receipt of the Indemnity
     Notice that the Indemnifying Party disputes such claim, the claim specified
     by the Indemnified Party in the Indemnity Notice shall be deemed a
     liability of the Indemnifying Party hereunder.  If the Indemnifying Party
     has timely


                                          24
<PAGE>

     disputed such claim, as provided above, such dispute shall be resolved by
     litigation in an appropriate court of competent jurisdiction if the parties
     do not reach a settlement of such dispute within thirty (30) days after
     notice of a dispute is given.

          (e)  Payments of all amounts owing by any Indemnifying Party pursuant
     to this ARTICLE  IX relating to a Third Party Claim shall be made within
     thirty (30) days after the latest of (i) the settlement of such Third Party
     Claim, (ii) the expiration of the period for appeal of a final adjudication
     of such Third Party Claim, or (iii) the expiration of the period for appeal
     of a final adjudication of the Indemnifying Party's liability to the
     Indemnified Party under this Agreement.  Payments of all amounts owing by
     the Indemnifying Party pursuant to SECTION 9.3(d) shall be made within ten
     (10) days after the later of (i) the expiration of the 30 -day Indemnity
     Notice period or (ii) the expiration of the period for appeal of a final
     adjudication of the Indemnifying Party's liability to the Indemnified Party
     under this Agreement.

          (f)  The Indemnifying Party shall provide the Indemnified Party with
     written notice of any firm offer that is made to settle or compromise a
     Third Party Claim against an Indemnified Party.  If a firm offer is made to
     settle such a claim solely by the payment of money damages and the
     Indemnifying Party notifies the Indemnified Party in writing that the
     Indemnifying Party agrees to such settlement, but the Indemnified Party
     elects not to accept and agree to it, the Indemnified Party may continue to
     contest or defend such Third Party Claim and, in such event, the total
     maximum liability of the Indemnifying Party to indemnify or otherwise
     reimburse the Indemnified Party hereunder with respect to such a claim
     shall be limited to and shall not exceed the amount of such settlement
     offer, plus reasonable out -of -pocket costs and reasonable expenses
     (including reasonable attorneys' fees and disbursements) to the date of
     notice that the Indemnifying Party desired to accept such settlement.

          (g)  Notwithstanding any provision herein to the contrary, the
     obligation of an Indemnifying Party to provide indemnification to an
     Indemnified Party for breach of any representation or warranty  shall not
     take effect unless and until the Damages asserted against or incurred in
     the aggregate and on a collective basis by the Indemnified Parties pursuant
     to either SECTION 9.1 or 9.2 (as applicable) as a result of such a breach
     or breaches exceeds $15,000.

     9.4  TAX INDEMNIFICATION.

     (a)   Notwithstanding  anything in this Agreement to the contrary, each
of KREG and KHI shall indemnify KNHC, KDC and their Affiliates (including
KOC) and hold them harmless for, from and against (i) all liability for all
Taxes of KOC for all taxable periods ending on or before the Closing Date and
the portion ending on the Closing Date of any taxable period that includes
(but does not end on) the Closing Date ("PRE-CLOSING TAX PERIOD"), including,
without limitation, any liability for any Taxes imposed pursuant to Treasury
Regulation SECTION 1.1502-6 as a result of being a member of the affiliated
group, within the meaning of SECTION 1504 of the Code, of which KREG is a
member and liabilities for

                                   25

<PAGE>

any Taxes imposed in respect of the matters set forth in SCHEDULE 2.8, (ii)
assuming a valid, timely and effective election under Sections 338(g) and
338(h)(10) of the Code is made, as contemplated by SECTION 11.21 of this
Agreement (the "ELECTION"), all liability for Taxes accruing on or before the
Closing Date which result from (A) the Election, (B) any comparable elections
under state or local tax laws and (C) any deemed assets sales resulting from
the Election in any jurisdictions, including jurisdictions in which KOC files
its Tax Returns on a separate company basis and (iii) any liability for Taxes
attributable to a breach by KREG or KHI of any of its obligations under this
Agreement.

     (b)  KDC shall indemnify KREG and its Affiliates and hold them harmless
for, from and against all liability for Taxes of KOC for any taxable period
commencing after the Closing Date.

     (c)  In the case of any taxable period that includes (but does not end on)
the Closing Date ("Straddle Period"), the Taxes of KOC for the Pre-Closing Tax
Period shall be computed as if such taxable period ended on and included the
Closing Date (and included any income from any deemed assets sale).

     9.5  PROCEDURES RELATING TO INDEMNIFICATION OF TAX CLAIMS.

     (a)  If a claim for Taxes shall be made by any taxing authority in writing,
which, if successful, might result in an indemnity payment pursuant to SECTION
9.4, the Indemnified Party shall promptly notify the Indemnifying Party in
writing of such claim (a "TAX CLAIM").  If notice of a Tax Claim (a "TAX
NOTICE") is not given to the Indemnifying Party within a reasonably sufficient
period of time to allow the Indemnifying Party effectively to contest such Tax
Claim, or in reasonable detail to apprize the Indemnifying Party of the nature
of the Tax Claim, taking into account the facts and circumstances with respect
to such Tax Claim, the Indemnifying Party shall not be liable to the Indemnified
Party or any of its affiliates to the extent that the Indemnifying Party's
position is actually prejudiced as a result thereof.

     (b)  With respect to any Tax Claim which might result in an indemnity
payment to KNHC, KDC or any of their Affiliates pursuant to SECTION 9.4 (other
than a Tax Claim relating to Taxes of KOC for a Straddle Period), and provided
that KREG shall first have admitted its liability to KNHC, KDC or any of their
Affiliates as the case may be, KREG shall control all proceedings taken in
connection with such Tax Claim (including, without limitation, selection of
counsel) and, without limitation of the foregoing, may in its sole discretion
and at its sole expense pursue or forego any and all administrative appeals,
proceedings, hearings and conferences with any taxing authority with respect
thereto, and may, in its sole discretion, either pay the Tax claimed and sue for
a refund where applicable law permits such refund suits or contest such Tax
Claim in any permissible manner.  In no case shall KNHC, KDC or KOC settle or
otherwise compromise any Tax Claim referred to in the preceding sentence without
KREG's prior written consent.  KNHC, KDC, KOC and their affiliates shall
cooperate with KREG in contesting such Tax Claim, which cooperation shall
include, without limitation, the reasonable retention and (upon KREG's


                                          26
<PAGE>

     request) the provision to KREG of records and information which are
     reasonably relevant to such Tax Claim, and making employees reasonably
     available to provide additional information or explanation of any material
     provided hereunder or to testify at proceedings relating to such Tax Claim,
     all at KREG's expense.

     (c)   The contest of any Tax Claim that relates to Taxes of KOC for a
Straddle Period shall be controlled by KDC (or, if required by law, KNHC) and
KREG agrees, and agrees to cause its affiliates, to cooperate with KNHC, KDC
(and their Affiliates) in pursuing such contest.  KREG shall be kept informed of
any such contest and shall have the right to participate, or have its legal
counsel or advisors participate, at its expense.  KDC shall not settle any claim
with any taxing authority with respect to taxes for a Straddle Period unless (i)
KREG shall have agreed in writing to such settlement, such agreement not to be
unreasonably withheld, and (ii) KREG and KDC shall have agreed on an
apportionment of the proposed settlement liability amongst the Pre-Closing Tax
Period and the portion of the Straddle Period commencing on the day after the
Closing Date.  To the extent KDC is represented in any discussions with any
taxing authority with respect to taxes for a Straddle Period, such
representatives shall owe an equal duty to both KDC and KREG.

instrument pursuant to SECTION 11.1 ), delay, indulgence, omission or otherwise
be deemed to have waived any right or remedy hereunder or to have acquiesced in
any default in or breach of any of the terms and conditions hereof.  No failure

single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege.  No remedy set forth in this Agreement or otherwise
conferred upon or reserved to any party shall be considered exclusive of any
other remedy available to any party, but the same shall be distinct, separate
and cumulative and may be exercised from time to time as often as occasion may
arise or as may be deemed expedient.

     11.15  TERMINATION PRIOR TO CLOSING.  This Agreement and the transactions
contemplated hereby may be terminated (a) at any time prior to the Closing by
mutual agreement of all parties; or (b) by any party hereto if the Closing of
this Agreement and the consummation of the transactions contemplated hereby

extended pursuant to SECTION 4.1, by KNHC pursuant to SECTION 7.4 or is
otherwise mutually extended by all parties; (c) by KREG or KHI in the event of

days after the date of such termination.  In the event of a termination of this
Agreement pursuant to SECTION 4.1, KREG shall pay to KDC on the date of

and each and every remedy shall be cumulative and shall be in addition to every
other remedy given hereunder or now or hereafter existing at law or in equity or
by statute or otherwise.  The election of anyone or more remedies by any party
hereto shall not constitute a waiver of the right to pursue other available
remedies.

     11.18  COSTS, EXPENSES AND LEGAL FEES.  Whether or not the transactions
contemplated hereby are consummated, each party hereto shall bear its own costs
and expenses (including attorneys' fees and expenses), except that (a)  KNHC and

Code (and any comparable election under state or local tax law), (ii) KREG and
KNHC shall jointly make the election provided for by SECTION 338(h)(10) of the
Code (the "Election") and KREG and KNHC shall, as promptly as practicable

necessary and appropriate (including filing such forms, returns, elections,
schedules and other documents as may be required) to effect and preserve a
timely Election in accordance with the provisions of Treasury Regulation SECTION
1.338(h)(10)-1(d) (or any comparable provisions of state or local tax law) or

                                          33
<PAGE>

position to the contrary thereto in any Tax Return, any proceeding before any
taxing authority, or otherwise.

     (b)    In connection with the Election, KREG and KNHC shall act together in
good faith to agree on the Aggregate Deemed Sales Price and Adjusted Grossed-up
Basis (as defined under applicable Treasury Regulations) and the allocation of
such Adjusted Grossed-up Basis among the assets of KOC and any corporate
Affiliate of KOC for which an Election has been made.  Such allocation of the
Adjusted Grossed-up Basis shall be made in accordance with section 338(b) of the
Code and any applicable Treasury Regulations.  KREG and KNHC (i) shall be bound
by such allocation for purposes of determining any Taxes; (ii) shall prepare and
file all Tax Returns to be filed with any taxing authority in a manner
consistent with such allocation; and (iii) shall take no position inconsistent
with such allocation in any Tax Return, any proceeding before any taxing
authority or otherwise.  In the event that such allocation is disputed by any
taxing authority, the party receiving notice of such dispute shall promptly
notify and consult with the other party hereto concerning resolution of such
dispute.

     11.22  SURVIVAL OF TAX PROVISIONS.  Any claim to be made pursuant to

extensions) of the applicable statutes of limitations relating to the Taxes at
issue.

     11.23  REAL AND PERSONAL PROPERTY TAXES.  KREG shall pay or cause to be
paid any and all liabilities of KOC for real and personal property taxes and
assessments relating to all periods ending on or prior to December 31, 1997.
KDC shall pay or cause to be paid any and all liabilities of KOC for real and
personal property taxes and assessments relating to taxable periods commencing
on or after January 1, 1998, provided that with respect to periods prior to the
Closing Date, personal property taxes and adjustments (but not real property
taxes and adjustments which are capitalized) shall be taken into account in
determining the 1998 Activity Consideration as set forth in SCHEDULE 1.2.

     11.24  TRANSFER TAXES.  Notwithstanding any other provisions of this
Agreement to the contrary, KDC and KREG shall pay, or cause to be paid, equal

if any, required to be paid in connection with KDC's purchase of the Stock
pursuant to this Agreement.

     11.25  RETURN FILINGS, REFUNDS AND CREDITS.

     (a)  KREG shall prepare or cause to be prepared and file or cause to be
filed on a timely basis (in each case, at its own cost and expense and in a
manner consistent with past practice) all Tax Returns with respect to KOC for
taxable periods ending on or prior to the Closing Date.  KREG shall provide KOC
with copies of such Tax Returns (which, with respect to Tax Returns that relate
to an affiliated or combined group that includes KOC, shall be "pro-forma"
returns) covering any taxable period beginning on January 1, 1998 and ending on
or prior to the Closing Date, on or prior to the due date thereof (including any
extensions thereto). KREG shall pay all Taxes shown on all such Tax Returns.


                                          34
<PAGE>

     (b)    KDC shall prepare or cause to be prepared and shall file or cause to
be filed on a timely basis all other Tax Returns with respect to KOC.  In
connection therewith, KDC shall be responsible for and shall pay any Taxes for
which KDC has agreed to indemnify KREG pursuant to SECTION 9.4 hereof. In filing
its return for purposes of Texas franchise tax, KDC shall treat any income from
the deemed sale of assets attributable to the sale of partnership interests
owned by KOC as a sale of intangible assets and net gain attributable to such
deemed sale shall be included only in the denominator of the gross receipts
apportionment formula because it is apportioned (attributed) to the location,
i.e. the legal domicile, of the payor in accordance with Texas Regulation, 34
TAC Sec. 3.549.  KDC shall provide KREG with copies of any such Tax Returns
covering Taxes for which KREG has agreed to indemnify KNHC, KDC and their
Affiliates (including KOC) pursuant to SECTION 9.4 hereof at least ten (10) days
prior to the due date thereof (giving effect to the extensions thereto),
accompanied by a statement calculating KREG's indemnification obligation
pursuant to SECTION 9.4 hereof.  KREG shall pay to KDC the amount of KREG's
indemnification obligation within ten (10) days of receiving copies of such Tax
Returns unless the parties are unable to agree on the amount of KREG's
indemnification obligation hereunder in which case such dispute shall be
resolved by independent accountants acceptable to both parties whose fees and
expenses shall be paid by KREG and KDC in proportion to each party's respective
liability for Taxes as determined by such accountants, and KREG shall pay the
amount determined by such accountants within ten (10) days of such
determination.

     (c)    KREG, KOC, KNHC and KDC shall reasonably cooperate, and shall cause
their respective affiliates, officers, employees, agents, auditors and
representatives reasonably to cooperate, in preparing and filing all Tax Returns
(including amended returns and claims for refund), including maintaining and
making available to each other all records necessary in connection with Taxes
and in resolving all disputes and audits with respect to all taxable periods
relating to Taxes.  KDC and KREG recognize that KREG and its affiliates will
need access, from time to time, after the Closing Date, to certain accounting
and tax records and information held by KOC to the extent such records and
information pertain to events prior to the Closing Date; therefore, KDC agrees
that (i) from and after the Closing Date until the eighteenth anniversary of the
Closing Date, KDC shall, and shall cause KOC to, (A) use all reasonable efforts
to properly retain and maintain such records until such time as KREG agrees that
such retention and maintenance is no longer necessary, and (B) allow KREG and
its agents and representatives (and agents or representatives of any of its
affiliates), to inspect, review and make copies of such records as KREG may deem
necessary or appropriate from time to time, such activities to be conducted
during normal business hours and at KREG's sole expense and (ii) from and after
the eighteenth anniversary of the Closing Date, KDC shall not, and shall cause
KOC not to, dispose of any of such records without first providing KREG with an
opportunity to take possession of such records or to make copies thereof, at
KREG's sole expense, prior to any such disposal.

     (d)    Any refunds or credits of Taxes of KOC for any taxable period ending
on or before the Closing Date shall be for the account of KREG.  Any refunds or
credits of Taxes of KOC for any taxable period beginning after the Closing Date
shall be for the account of


                                          35
<PAGE>

KDC and shall be paid by KREG to KDC within 10 days after KREG receives such
refund.  Any refunds or credits of Taxes of KOC for any Straddle Period shall be
apportioned between KREG and KDC on the basis of the "interim closing of the
books". If KDC in good faith determines that it will not have any adverse effect
on its Tax liability, KDC shall, if KREG so requests and at KREG's sole expense,
cause KOC to file for and obtain any refunds or credits which KREG is entitled
under this SECTION 11.23.  If KDC makes such good faith determination, KDC shall
cause KOC to forward to KREG any such refund within 10 days after the refund is
received (or reimburse KREG for any such credit within 10 days after the
relevant Tax Return is filed in which the credit is actually applied against
KOC's liability for Taxes).

     11.26  CONSISTENT TAX POSITIONS.  KNHC and KDC (and by written
acknowledgement hereto KOC) covenant and agree that neither KOC nor any of
its subsidiaries shall take a position, for federal income tax purposes and
comparable state and local tax purposes (including in connection with any
examination or audit by any tax authority or other proceeding), inconsistent
with the position that (a) the federal consolidated group of which KREG is
the common parent (the "KREG Group") underwent an ownership change within the
meaning of SECTION 382 of the Code as a result of the bankruptcy
reorganization of KREG in 1997, (b) the provisions of SECTION 382(1)(5) apply
to such ownership change, and (c) that each member of the KREG Group is
subject to the provisions of SECTION 382(1)(5) of the Code in the respect of
such ownership change; PROVIDED, HOWEVER, that if KREG elects not to apply
the provisions of SECTION 382(1)(5) of the Code, this provision shall not
apply.  Accordingly, subject to the provision in the preceding sentence, KOC
and its subsidiaries shall treat the purchase of the stock of KOC pursuant to
this Agreement as a second ownership change within the meaning of SECTION
382(1)(5)(D) of the Code and under any comparable provisions of state and
local law.  In furtherance of the foregoing, KOC further agrees to execute
and deliver, and to cause its subsidiaries to execute and deliver, to KREG
such other documents or agreements evidencing the foregoing and compliance
therewith, if and when reasonably requested by KREG.

     11.27  TERMINATION OF TAX SHARING AGREEMENTS.  KREG hereby agrees and
covenants that any obligation of KOC pursuant to any tax sharing agreement or
similar arrangements shall be terminated on or before the Closing Date, and
no payments pursuant to any such tax sharing agreement or arrangements shall
be made after such termination.

                                NOTES TO BALANCE SHEET


Note 1      Basis of Presentation

            The financial statements of KREG Operating Co. (the "Company"), an
            indirect wholly-owned subsidiary of Koll Real Estate Group, Inc.
            (the "Parent"), are internally prepared and unaudited. Certain
            information and substantially all footnote disclosures normally
            included in financial statements prepared in accordance with
            generally accepted accounting principles have been condensed or
            omitted. The Company began business on September 30, 1993, upon its
            acquisition of the domestic development operations of The Koll
            Company.

Note 2      Reorganization value in excess of amounts allocated to net assets

            Reorganization value in excess of amounts allocated to net assets
            arose from the adoption of Fresh-Start Reporting upon the Parent's
            completion of its recapitalization on September 2, 1997 and is
            being amortized on a straight-line basis over 15 years.

Note 3      Income taxes

            The Company is included in the consolidated tax returns of the
            Parent and no current or deferred tax provisions are reflected in
            the accompanying balance sheet from inception.

NEWS RELEASE - DRAFT DATED 3/30/98

Contact:  Raymond J. Pacini, Chief Financial Officer, 714-833-3025 X291


          KREG ANNOUNCES AGREEMENT TO SELL COMMERCIAL DEVELOPMENT BUSINESS

                - COMPANY PLANS TO FOCUS ON RESIDENTIAL BUSINESS


     NEWPORT BEACH, California -- March 31, 1998 - Koll Real Estate Group,
Inc. (NASDAQ:KREG) announced today that it has executed a definitive
agreement with Koll Development Company LLC ("KDC") and an affiliated
company, for the sale of the Company's commercial development business for
(1) $30 million in cash plus adjustments for 1998 activity; and (2) the
assumption by KDC of all liabilities related to the business.

     KDC is a newly formed limited liability company, whose members include
the Company's current Chairman and Chief Executive Officer, Donald M. Koll
and its President, Richard M. Ortwein. Upon completion of the transaction,
Messrs. Koll and Ortwein will resign from their current positions with the
Company, and the Company will change its name to discontinue use of the
"Koll" name.

     The Company also announced that, effective upon completion of the
transaction, Raymond J. Pacini will be appointed as the Company's new
President and Chief Executive Officer. Mr. Pacini has been the Chief
Financial Officer of the Company since 1992 and has 18 years of experience
with publicly traded companies, including 10 years in real estate
development. Prior to moving to the Company's headquarters in Newport Beach,
CA in 1990, Mr. Pacini held various financial management positions with the
Company's predecessor, The Henley Group, Inc. from 1986 to 1989 in Hampton,
NH. From 1979 to 1986, he was a C.P.A. with the "Big Six" accounting firm of
Coopers & Lybrand in Boston, MA.

     In approving the transaction, the Company's Board of Directors accepted
a recommendation from a Special Committee of independent directors that had
negotiated with KDC that the terms of the proposed sale of the commercial
development business to KDC are fair to, and in the best interests of, the
Company and its shareholders.

     Mr. Koll stated, "This transaction is beneficial to all parties
concerned. The Company and its shareholders will receive necessary capital to
continue development of its existing land inventory, while the commercial
group will be better positioned to focus on its core competency, which is the
development of office, industrial and retail real estate across the United
States and Asia."

          Mr. Pacini commented, "We believe the residential real estate
market in California is one of the best in this state's history.  By selling
the commercial development business, the Company will be in a position to
focus exclusively on maximizing the value of its significant residential land
holdings.  Our residential team, which includes Lucy Dunn, Senior Vice
President; Ed Mountford, Vice President; and Mike Rafferty, the President
of our homebuilding subsidiary, will remain with the Company to lead the
litigation process and the ultimate development of the Bolsa Chica property.
This infusion of cash allows the Company to vigorously defend its land use
entitlements at Bolsa Chica through the pending court appeals and commence
construction immediately thereafter." The Company also is developing
master-planned communities elsewhere in Southern California, in Aliso Viejo
(1,200 homes), Escondido (580 homes) and Fairbanks Highlands (a 93-home joint
venture).

     KREG received a deposit of $1 million from KDC upon execution of the
definitive agreement, which is nonrefundable except under limited
circumstances, including if a higher offer for the commercial development
business ultimately is accepted by the Company, in which case KDC also would
be paid a break-up fee of $2 million plus up to $500,000 for legal and other
advisory fees. In the event that a higher offer is accepted, Messrs. Koll
and Ortwein would not be obligated to perform any services for the acquiror
and would have the right to immediately be released from their employment
agreements with the Company, including their covenants-not-to-compete.

          As noted above, the definitive agreement was unanimously approved
by a Special Committee of independant directors, which commissioned an
investment banking firm, The Blackstone Group L.P., to provide advice on
strategic alternatives and the fairness of the proposed terms of the
transaction. The Special Committee has directed

the Company's management and The Blackstone Group L.P. to be available to
receive inquiries from any other parties interested in the possible
acquisition of the commercial development business and, if appropriate, to
provide information and enter into discussions and negotiations with such
parties in connection with any such indicated interest.

          The transaction is scheduled to be completed on April 30, 1998,
subject to various conditions, unless extended by agreement of the parties.
The Company expects to realize a gain on this transaction of approximately
$9.5 million; however, there can be no assurance that the transaction with

                             1998 Activity Consideration

NOTES TO SCHEDULE 1.2

(A)  Interest carry on the $30 million Purchase Price from January 1, 1998
through March 31, 1998 shall be calculated  using a simple interest rate of
13.5% per annum based on a 360 day year (i.e. $30 million * 13.5% / 360 * 90
days = $1,012,500).  In the event that KNSH elects to defer the Closing Date
in accordance with Section 7.4, then interest carry on the $30 million
Purchase Price shall be increased for the period from May 1, 1998 through the
Closing Date using a simple interest rate of 12% per annum based on a 360 day
year.

(B) Net Cash Used By Operations Before Asset Sales shall be calculated based
on KOC's standard monthly financial reports (see 1.2 - 4) in a manner
consistent with Schedule 1.2 and the notes thereto, and includes an agreed
upon allocation of Corporate overhead of $50,000 per quarter, or $16,667 per
month (see 1.2 -3).

(C) For Net Cash Used By Operations Before new Project Equity Investments and
Asset Sales Activity, interest on the average monthly balance (which shall be
calculated beginning 1/1/98 by adding net cumulative cash flow as of the
beginning of the month plus net cumulative cash flow as of the end of the
month and dividing by 2) shall be calculated using a rate of 13.5% per annum,
or 1.125% per month for each month between 1/1/98 and 3/31/98, and at a rate
of 12% per annum, or 1.00% per month or portion thereof from 4/1/98 through
closing. Such calculation shall include the agreed upon allocation of
Corporate overhead of $16,667 per month. For Net Asset Sales Activity,
interest shall be credited @ a rate of .0375% per day (1.125% per month)
prior to 3/31/98 and @ a rate of .0333% per day (1.00% per month) from 4/1/98
through closing, and shall be calculated on the daily balance from the date
funds are received by KREG.

(D)  See 1.2 - 3

(E)  For new Project Equity Investments after January 1, 1998, the preferred
return shall be calculated on the daily balance from the date such Project
Equity Investment is made through and including the Closing Date at a rate of
25% per annum, or .0694444% per day based on a 360 day year from 1/1/98
through 3/31/98 and @ a rate of .0333% per day (1.00% per month) from 4/1/98
through closing.  Project Equity Investments shall include partial fundings
in advance of project loan fundings where KREG is the intended equity source
from the beginning (i.e. Disney project where KREG funded land purchase prior
to loan closing).

(F)  To be adjusted to reflect best estimate one day prior to Closing Date
and further adjusted to reflect actual within 30 days of Closing Date.

                                     SCHEDULE 2.8

     The Internal Revenue Service ("IRS") has completed its examinations of the
tax returns of KREG and its consolidated subsidiaries, including formerly
affiliated entities, for the years ended December 31, 1989, 1990 and 1991. With
respect to each examination, the IRS has proposed material audit adjustments.
KREG disagrees with the positions taken by the IRS and has filed a protest with
the IRS to vigorously contest the proposed adjustments. After review of the
IRS's proposed adjustments, KREG estimates that, if upheld, the adjustments
could result in Federal tax liability, before interest, of approximately $17
million (net of amounts which may be payable by former affiliates pursuant to
tax sharing agreements). The IRS proposed adjustments, if upheld, could result
in a disallowance of up to $132 million of available NOL carryforwards, of which
none are recognized after consideration of the valuation allowance, as of
September 30, 1997. KREG has not determined the extent of potential accompanying
state tax liability adjustments should the proposed IRS adjustments be upheld.
KREG's protest was filed in August 1995 and is being considered by the IRS
Appeals Division. Management currently believes that the IRS's positions will
not ultimately result in any material adjustments to KREG's financial
statements. KREG is prepared to pursue all available administrative and judicial
appeal procedures with regard to this matter and KREG is advised that its
dispute with the IRS could take up to five years to resolve.

NOTES:
     *    Amounts to be estimated one day prior to Closing Date for the purpose
          of determining the amount to be paid on the Closing Date. Within
          thirty (30) days after the Closing Date a final accounting shall be
          completed and reviewed by the accounting staffs of KDP and KREG and
          any adjustments shall be paid in the same manner as set forth in
          Section 1.2 (c).

     **   If closing does not occur on a month-end, then KOC would owe KREG
          reimbursement for salaries, payroll taxes, benefits, rent and other
          overhead for any stub period between the closing date and the end of
          the next payroll period for D. Koll, J. Dubbs and M. Roylance (assumes
          these 3 KREG employees stay on KREG payroll until the end of a pay
          period; alternatively, KREG could remove these people from its payroll
          as of closing date if that is more convenient. However, since rent and
          related overhead costs are paid by KREG in advance, KOC would owe KREG
          for such costs for any stub period.)
