similarly located.

          5.2    RE-PRORATION OF IMPOSITIONS. If the real property taxes, water

finally fixed before the Cutoff Date, the apportionments thereof made at the
Closing shall be based upon the real property taxes, water rates and charges and
sewer taxes and rents assessed

                                                                              11

for the preceding fiscal year or applicable billing period and, after the real
property taxes, water rates and charges and sewer taxes and rents are finally
fixed, the KRF3/KR5 Transferor and the Partnership shall make a recalculation of
the apportionment of the same, and the KRF3/KR5 Transferor or the Partnership,
as the case may be, shall promptly make an appropriate settlement with the other
based upon such recalculation.

          5.3    UTILITIES. Water rates and charges, sewer taxes and rents and
gas and electricity charges for the Properties shall be prorated pursuant to
Section 5.1, based upon the per diem charges obtained by using the most recent
period for which such readings shall then be available. On the subsequent taking
of actual readings, the apportionment of such charges shall be recalculated and
the apportionment between the KRF3/KR5 Transferor and the Partnership readjusted
and settled based upon such readings.

          5.4    RENT ARREARAGES. Rents collected or received from a Tenant
which, as of the Closing Date, was in arrears in the payment of Rents, shall be
applied as follows: (i) in the case of Rents received from a Tenant which, as at
the Cutoff Date, was not more than two (2) months in arrears in the payment of
Rents, the Rents so collected shall be applied first to such arrears and then to
any other amounts which may then be due after the Cutoff Date; and (ii) in the
case of Rents received from a Tenant which, as at the Cutoff Date, was more than
two (2) months in arrears in the payment of Rents, the Rents so collected shall
first be applied to any amounts due after the Cutoff Date and any balance
remaining shall be applied to the arrears. All costs and expenses incurred by
the Owner Entities in bringing any action or proceeding to collect Rent
Arrearages from any Tenant who is delinquent on the Closing Date shall, to the
extent of the Partnership's (or the applicable Subsidiary's) share thereof under
the KRF3 Tenancy-in-Common Agreement and the Century Operating Agreement, be
borne by the Partnership and the KRF3/KR5 Transferor in proportion to the
collected amounts (or the share thereof) to which each may be entitled hereunder
and the KRF3/KR5 Transferor's portion may be deducted from the amounts otherwise
to be remitted to the KRF3/KR5 Transferor. The KRF3/KR5 Transferor shall have no
right with respect to Rent Arrearages collected after the Final Adjustment Date;
PROVIDED, HOWEVER, if an Owner Entity shall institute a legal action or
litigation to collect any portion of such Rent Arrearages after the Closing Date
and prior to the Final Adjustment Date, the KRF3/KR5 Transferor shall retain the
right to receive its share of such Rent Arrearages, net of litigation costs and
expenses, if collected.

          5.5    SECURITY DEPOSITS. The Schedule of Leases includes a schedule
setting forth the unapplied portion of any security deposits which have been
deposited with the Owner Entities or their agents (or with any predecessors in
interest to the Owner Entities with respect to the Properties to the extent said
predecessors have turned over security deposits to an Owner Entity or given an
Owner Entity a credit therefor) by any Tenants. The KRF3/KR5 Transferor shall
pay to the Partnership in cash at the Closing the KRF3/KR5 Transferor's share of
the aggregate amount of the security deposits set forth on such schedule which
are no longer on deposit with the Owner Entities. The Partnership shall pay to
the KRF3/KR5 Transferor in cash at the Closing the KRF3/KR5 Transferor's share
of the aggregate amount of interest accrued prior to the Closing Date

                                                                              12

on any security deposits held by the Owner Entities except to the extent such
interest is required to be paid to any Tenants pursuant to their respective
Leases.

          5.6    RESERVES AND DEPOSITS. The KRF3/KR5 Transferor's share of the
amount of any reserves, escrow deposits or accruals made with, or held by, the
holders of any Mortgages or any insurance carriers, together with all interest
earned thereon, if any, which is payable to the Owner Entities, for real
property taxes and assessments, insurance premiums or other items shall be paid
to the KRF3/KR5 Transferor at the Closing by the Partnership.

          5.7    SETTLEMENT OF ADJUSTMENTS.

                 (A)    On or before the Final Adjustment Date, the adjustments
made as of the Closing Date shall be adjusted for any differences between the
actual apportionment or adjustment based on calculations as of the Cutoff Date
and the amount thereof estimated on the Closing Date and the net amount of any
such adjustments shall be paid to the Partnership or to the KRF3/KR5 Transferor.
Any payments which are due on or after the Final Adjustment Date and are
attributable to periods on or before the Cutoff Date will be apportioned within
ninety (90) days of receipt of such payment and the net amount of any such
adjustments shall be paid to the Partnership or to the KRF3/KR5 Transferor.

                 (B)    Any errors or omissions in computing apportionments at
the Closing shall be corrected promptly after their discovery.

                 (C)    Net prorations and adjustments made pursuant to this
Article V as of the Closing Date and from time to time after the Closing shall
be made in cash.

          5.8    INSPECTION OF BOOKS AND RECORDS. Prior to Closing and upon
request of the Partnership, the KRF3/KR5 Transferor shall from time to time make
available for inspection by the Partnership or its designee, at the place or
places where they are regularly kept and maintained, during reasonable business
hours, the records and books of account relating to the Properties and, during
such inspection, shall permit extracts and copies to be made from said records
and books of account, at the Partnership's expense. The KRF3/KR5 Transferor
shall have the right from time to time subsequent to the Closing to examine and
audit the records and books of account relating to the Properties.

          5.9    [SCHEDULE OF RENT ARREARAGES. Attached as EXHIBIT J hereto is a
schedule of Rent Arrearages (the "SCHEDULE OF RENT ARREARAGES"), which schedule
sets forth each Tenant which is in arrears under a Lease and the items of Rents
with respect to which such Tenant is in arrears as of the Cutoff Date, the
amount of each item and the period of such arrearage.]

          5.10   SURVIVAL. Unless otherwise provided in this Article V, the
provisions of this Article V shall survive until thirty days after the Final
Adjustment Date except with respect to claims made prior to the end of such
thirty-day period.

to any other representations and warranties of the Transferors herein contained,
the Transferors represent and warrant to the Partnership and Partnership Sub as
follows:

                 (A)    CONFLICTS. The execution and delivery of the Agreement
and the consummation of the transactions contemplated hereby by the Transferors
does not and will not (i) violate or conflict with the operating agreement of
the KRF3/KR5 Transferor or the organizational documents of the GP Transferor,
KRF3, KR5 or any

<Page>

                                                                              20

Subsidiary, (ii) violate or conflict with any judgment, decree or order of any
court applicable to or affecting either of the Transferors, KRF3, KR5 or any
Subsidiary, (iii) assuming all required consents of third parties are obtained,
breach the provisions of, or constitute a default under, any contract, mortgage,
loan agreement, note, lease, joint venture or partnership agreement or other
instrument or agreement obligation to which either of the Transferors, KRF3, KR5
or any Subsidiary is a party or by which the Transferors, KRF3, KR5 or any
Subsidiary is bound (including without limitation the KRF3 Tenancy-in-Common
Agreement or the Century Operating Agreement), (iv) violate or conflict with any
law or governmental regulation or permit applicable to Transferors, KRF3, KR5 or
any Subsidiary, or (v) require any authorization, approval, consent, license,
exemption of or filing or registration (in each case, a "consent") with any
court or governmental department, commission, board, bureau, agency or
instrumentality, foreign or domestic or any other person or entity (except for
those consents listed in Schedule 7.6 (A) hereto), which consents have been
obtained and true and correct copies of which consents have been made available
to the Partnership.

                 (B)    LEASES. The Schedule of Leases (the "SCHEDULE OF
LEASES") sets forth with respect to each Lease (whether or not the terms of each
Lease has commenced as of the date of such Schedule) (i) the name of the Tenant
under each Lease, (ii) the commencement date of such Lease, (iii) the term of
such Lease and (iv) the annual rent payable by such Tenant. This Schedule of
Leases is complete and accurate in all material respects, and originals and/or
true and complete copies of each such Lease, each modification, amendment,
extension and assignment thereof, have heretofore either been furnished to the
Partnership or been made available to the Partnership for inspection. To the
Transferors' knowledge, there are no other leases affecting any portion of the
Properties except as set forth on the Schedule of Leases and except for those,
if any, entered into after the date of such Schedule in the ordinary course of
business consistent with past practices of the Owner Entities. No Tenant has
paid more than one month's rent or other charges in advance, except for security
deposits.

                 (C)    MODIFICATION OF LEASES. The Leases are unmodified and in
full force and effect as of the date of the Schedules of Leases [(except for
those designated on the Schedule of Leases as "out for signature"), and
constitute the sole agreements and understandings (written or oral) between the
Owner Entities and the parties thereto. There have been no changes in the Leases
since the date of such Schedules except for those made in the ordinary course of
business.

                 (D)    LEASE DEFAULTS. Except as set forth in the Schedule of
Rent Arrearages and the schedule of litigation attached as EXHIBIT K hereto (the
"SCHEDULE OF LITIGATION"), no action, proceeding or arbitration is pending in
respect of any Lease, the resolution of which would have a material adverse
effect on any of the Properties, and except as set forth in the Schedule of Rent
Arrearages, (i) the Transferors have no actual knowledge of any breaches of or
defaults under any Lease by the Tenant or landlord thereunder which, in the
aggregate for any Property, would have a material adverse effect on such
Property, and (ii) all payments payable by or due to the Owner Entities under
any Lease to the date of such Schedule have been made and received without any
material default thereunder or, to the Transferors' knowledge, without any
defenses,

<Page>

                                                                              21

counterclaims, offsets, concessions, rebates, credits or allowances having been
claimed or given.

                 (E)    SECURITY DEPOSITS. All security deposits that have been
paid to the Owner Entities by or on behalf of any of the Tenants are as set
forth in EXHIBIT L.

                 (F)    VIOLATIONS. None of the Transferors, KRF3, KR5 and any
Subsidiary has received written notice from any governmental authority claiming
or noting with respect to any Property any violation of any federal or local
law, regulation, requirement or ordinance, which violation remains uncured,
except as set forth in EXHIBIT M.

                 (G)    LIABILITIES. Except for (i) obligations and liabilities
referred to, or contained in or arising under agreements referred to, in this
Agreement (including without limitation the Leases, the Mortgages, the Service
Contracts, the Operating Agreements, the KRF3 Tenant-in-Common Agreement, the
Century Operating Agreement and the other organizational documents of KRF3, KR5
and the Subsidiaries), including obligations and liabilities for which
adjustments are being made under Article V, (ii) matters affecting title to the
Properties (including real estate taxes and water and sewer rents not yet due
and payable), (iii) requirements of law generally applicable to the Properties
and/or KRF3, KR5 and the Subsidiaries (including laws imposing taxes,
assessments or other charges or the submission of reports or returns with
respect thereto), [(iv) items set forth in the financial statements of KRF3, KR5
and the Subsidiaries], (v) matters which are the subject of the litigations
listed (or not required to be listed) in EXHIBIT K, (vi) other liabilities and
obligations arising in the ordinary course of business and (vii) items set forth
on EXHIBIT N, to the best of the Transferors' knowledge, none of KRF3, KR5, DOH
or any Subsidiary has any liabilities or obligations.

                 (H)    BUSINESS PURPOSE. KRF3, KR5, DOH and the Subsidiaries
have not engaged in any activity or business other than the ownership of
interests in Subsidiaries (in the case of KRF3 and KR5) or other Subsidiaries
(in the case of the Subsidiaries other than the Owner Entities) or the
acquisition, ownership, development, financing, leasing and management of the
Properties or interests therein and actions incidental thereto (in the case of
the Owner Entities).

                 (I)    EMPLOYEES. KRF3, KR5 and the Subsidiaries have no
employees other than those set forth on EXHIBIT O, for whom all applicable
governmental filings and tax payments have been made. There are no employment,
union, collective bargaining, or similar agreements or arrangements between
KRF3, KR5 or any of the Subsidiaries and any employees; and, to the Transferors'
knowledge and, except as set forth on EXHIBIT P, there are no pending claims
which have been asserted in writing or any threatened claim against KRF3, KR5 or
any of the Subsidiaries by or on behalf of any employees whose employment
relates to the Properties. DOH does not have, nor has it ever had, any
employees.

                                                                              22

                 (J)    TAX FILINGS. To the best of the Transferors' knowledge,
all Federal, state and local tax returns required to be filed by KRF3, KR5, DOH
and the Subsidiaries have been timely, duly and accurately completed and filed,
and all Federal, state and local taxes due and payable by any of such entities
have been paid in full, except as set forth on EXHIBIT R. No tax certiorari or
audit proceedings are currently pending with respect to the Properties except as
set forth on EXHIBIT S. The Transferors have delivered or made available to the
Partnership true, correct and complete copies of each such tax return in
Transferors' possession, if any, filed prior to the date hereof.

                 (K)    [FINANCIAL STATEMENTS. The financial statements of KRF3,
KR5 and the Subsidiaries for the most recent fiscal year fairly present, in all
material respects, their respective financial positions, their respective
operations and their respective cash flows for the periods indicated [,all in
accordance with generally accepted accounting principles consistently applied].
Such financial statements have been, in all material respects, accurately
derived from the books and records of such entities.]

                 (L)    INSURANCE. There is in full force and effect with
reputable insurance companies casualty and liability insurance with respect to
the Properties in compliance with the requirements contained in all applicable
Leases and Mortgages. No written notice of cancellation has been received by the
Transferors, DOH, KRF3, KR5 or any Subsidiary with respect to any insurance
policy maintained by any of such entities and, to the Transferors' knowledge,
none is threatened; and none of the Transferors, DOH, KRF3, KR5 and any
Subsidiary has received any written notice that any act is required to maintain
any such insurance policy which has not heretofore been accomplished.

                 (M)    SERVICE CONTRACTS. The Schedule of Contracts lists all
service contracts in effect with respect to the Properties (the "SERVICE
CONTRACTS"), if any, and except as set forth in the Schedule of Contracts, all
such Service Contracts are in full force and effect in accordance with their
respective terms as of the date of such Schedule and, together with the
Management Agreements, constitute the sole agreements and understandings
(written or oral) of the Transferors, DOH, KRF3, KR5 and any Subsidiary with
respect to the operation and maintenance of the Properties or any part thereof,
and to the Transferors' knowledge, such entities have not given and have not
received any written notice of default which remains outstanding with respect
thereto. The Transferors have no knowledge of any breaches of or defaults under
any service contracts by any party thereunder which would have a material
adverse effect on any of the Properties.

                 (N)    MANAGEMENT AGREEMENT. The Transferors have heretofore
delivered or made available to the Partnership true, correct and complete copies
of the Management Agreements. The Management Agreements have not been further
modified and are in full force and effect in accordance with their terms as of
the date hereof and constitute the sole agreements and understandings (written
or oral) of the Transferors, DOH, KRF3, KR5 and any Subsidiary with respect to
the management of the Properties or any part thereof. The Transferors have no
knowledge of any material breach of or material default under the Management
Agreements.

                 (O)    LEASING OR BROKERAGE COMMISSIONS. There are no leasing
or brokerage commissions which will be due after the Cutoff Date in respect of
any Leases.

                 (P)    LICENSES AND PERMITS. To the Transferors' knowledge, the
Owner Entities hold all licenses, permits and authorizations with respect to the
use, operation and occupancy of each Property the failure of which to hold would
have a materially adverse effect on the current ownership and operation of such
Property.

                 (Q)    ENVIRONMENTAL COMPLIANCE. The Transferors have
heretofore either furnished to the Partnership or made available to the
Partnership for inspection complete and accurate copies of all reports, studies,
analyses, Phase I reports, notices from any governmental authority,
correspondence or agreements with any person or governmental authority and
similar documents relating to environmental matters on, in or under the
Properties (collectively, the "ENVIRONMENTAL REPORTS"). Except as disclosed in
the Environmental Reports, none of the Transferors, DOH, KRF3, KR5 and any
Subsidiary has received any written notice from any governmental entity or other
person that the Properties, or current or former operations on the Properties,
are not or has not been in compliance with any Environmental Laws or that any
such entity has any material liability with respect thereto. To the Transferors'
knowledge, except as set forth in the Environmental Reports, there are no
underground tanks for Hazardous Materials, active or abandoned, at the
Properties and no Hazardous Materials have been released in a reportable
quantity (where such a quantity has been established by statute, ordinance,
rule, regulation or order) at, on or under the Properties.

                 (R)    CONDEMNATION. (i) No condemnation proceeding in which
the Transferors, DOH, KRF3, KR5 or any Subsidiary has been served with process
is pending with respect to all or any part of any Property, (ii) to the
Transferors' knowledge, no condemnation proceeding in which no such process has
been served is pending with respect to all or any part of any Property and (iii)
to the Transferors' knowledge, no taking in condemnation or by eminent domain is
threatened with respect to all or any part of any Property.

                 (S)    LITIGATION. Except as set forth on the Schedule of
Litigation, there is no litigation, action or suit which is not fully covered by
insurance, excluding deductible or retained amounts, and there is no
governmental, administrative or arbitration proceeding or investigation before
any court or governmental agency or body, domestic or foreign pending or, to the
Transferors' knowledge, threatened, before any court or governmental agency or
body, domestic or foreign, or any unsatisfied arbitration awards or judicial
orders against or affecting the Transferors, DOH, KRF3, KR5 or any of the
Subsidiaries or the Properties.

                 (T)    BANKRUPTCY. No attachments, execution proceedings,
assignments for the benefit of creditors, insolvency, bankruptcy, reorganization
or other similar proceedings are pending or, to the Transferors' knowledge,
threatened against the Transferors, DOH, KRF3, KR5 or any of the Subsidiaries,
nor are any of such proceedings anticipated or contemplated by the Transferors
or any of such entities.

                                                                              24

                 (U)    MORTGAGES. The Schedule of Mortgages sets forth with
respect to each Mortgage (i) the name of the holders thereof, (ii) the unpaid
principal balances as of the date hereof, (iii) the annual debt service
thereunder, (iv) the maturity date thereof, (v) the estimated balloon payment
due thereunder on maturity and (vi) the earliest date of which all notes secured
thereby can be prepaid. The Mortgages are in full force and effect, none of the
Transferors, DOH, KRF3, KR5 and any of the Subsidiaries has received any written
notice of default under any Mortgage, and, to the Transferors' knowledge, no
material default on the part of any Owner Entity or any other party thereto,
exists under any Mortgage and no event has occurred which with the giving of
notice or passage of time, or both, would constitute a material default under
any Mortgage. Originals and/or true and complete copies of each Mortgage, all
loan documents relating thereto, and each modification and amendment thereof
have heretofore either been furnished to the Partnership or been made available
to the Partnership for inspection.

                 (V)    TITLE.

                        (a)    EXHIBIT F accurately depicts (i) the ownership
interests of the KRF3/KR5 Transferor in KRF3 and KR5, (ii) the ownership
interests of the GP Transferor in WPT, Century Associates and DOH, (iii) the
ownership interests of KRF3, KR5 and the Subsidiaries (other than the Owner
Entities) in the Subsidiaries shown as being owned by such entities in such
Exhibits and (iv) to the best of Transferors' knowledge, the ownership interests
of third parties in the Subsidiaries or the Properties. All of such ownership
interests (other than those owned by third parties, as to which no
representation is made under this sentence) are held free and clear of all
Liens. Each of KRF3, KR5 and each Subsidiary is duly formed, validly existing
and in good standing under the laws of its state of formation and is in good
standing and duly qualified to conduct business in any state in which such
qualification is necessary. None of KRF3, KR5 or any Subsidiary has any
subsidiaries except as shown in EXHIBIT F.

                        (b)    Each Owner Entity holds a valid title insurance
policy ensuring its fee title to its Property (or, in the case of KRF3, its
interest as a 91.382% tenant-in-common in fee title to the KRF3 Properties),
free and clear of all Liens other than Permitted Exceptions and Liens which have
been discharged or otherwise terminated, and no Owner Entity has, since its
acquisition of its respective Property, done anything (other than the creation
of Permitted Exceptions and Liens which have been discharged or terminated in
full) to encumber its title to such Property.

                 (W)    EMPLOYEE BENEFIT PLANS. None of KRF3, KR5 and any of the
Subsidiaries maintains or has any liability under any employee benefit plan.

          7.7    REGARDING REPRESENTATIONS AND WARRANTIES. At the Closing, the
acknowledgments, representations and warranties in Sections 7.1, 7.2, 7.3, 7.4,
7.5 and 7.6 shall be deemed to have been remade on and as of the Closing Date,
provided that each party hereto shall, in the case of the representations and
warranties set forth in

<Page>

                                                                              25

Sections 7.3, 7.4, 7.5 and 7.6, have the option to update the same so that they
reflect facts and circumstances on a current basis.

          7.8    FAILURE TO SATISFY CONDITIONS PRECEDENT TO CLOSING.

                 (A)    If any representation or warranty made by the
Transferors, as updated, shall be untrue in any material respect on the Closing
Date (or if any update shall disclose changed facts or circumstances which alter
the representations and warranties previously made by the Transferors in any
material respect and which are not the result of actions permitted to be taken
by the Transferors under this Agreement and are not reasonably satisfactory to
the Partnership) or if any other condition precedent to the obligation of the
Partnership to consummate the transactions herein contemplated is unsatisfied as
of the Closing Date (including, the delivery of any KRF3/KR5 Transferor Closing
Documents or GP Transferor Closing Documents), the Partnership and Partnership
Sub shall have the right to terminate this Agreement by Notice in writing
delivered to the Transferors on or prior to the Closing Date, in which event
this Agreement, and the rights and obligations of the parties hereto (other than
rights and obligations which are expressly stated herein to survive the
termination of this Agreement), shall terminate upon delivery of such Notice
without liability on the part of any party hereto.

                 (B)    If any representation or warranty made by the
Partnership in Section 7.3, as updated, shall be untrue in any material respect
on the Closing Date (or if any update shall disclose facts or circumstances
which alter the representations and warranties previously made by the
Partnership in any material respect and which are not the result of actions
permitted to be taken by the Partnership under this Agreement and are not
reasonably satisfactory to the Transferors) or if the Partnership Closing
Documents or Partnership Sub Closing Documents identified in Section 6.3 or 6.4
have not been delivered on the Closing Date, the Transferors shall have the
right to elect to terminate this Agreement by Notice in writing delivered to the
Partnership on or prior to the Closing Date, in which event this Agreement, and
the rights and obligations of the parties hereto (other than rights and
obligations which are expressly stated herein to survive the termination of this
Agreement), shall terminate upon delivery of such Notice without liability on
the part of any party hereto.

          7.9    SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The representations
and warranties made by the Partnership and Partnership Sub in Section 7.3 and by
the Transferors in Sections 7.4. 7.5 and 7.6, as updated as of the Closing Date,
shall survive for one year after the Closing Date; provided, however that no
claim for breach of any representation or warranty in Sections 7.3, 7.4, 7.5 or
7.6 or for indemnification under Section 7.10 may be maintained by the
Partnership, Partnership Sub, or the Transferors unless the Partnership,
Partnership Sub, or the Transferors, as the case may be, shall have delivered a
written Notice specifying in reasonable detail such claim to the Partnership,
Partnership Sub, or the Transferors, as applicable, which Notice shall be
delivered for any representation or warranty in Sections 7.3, 7.4, 7.5 or 7.6 on
or before the first anniversary of the Closing Date (and, if such Notice is so
delivered, such claim shall survive until the expiration of the statute of
limitations applicable thereto).

                                                                              26

          7.10   INDEMNIFICATION.

                 (A)    Subject to the limitations set forth in Section 7.11 and
the provisions of Section 7.9, the Partnership shall indemnify and hold the
Transferors and each member or shareholder thereof (and their respective
officers, directors and employees) harmless from and against any claim, loss,
damage, expense, cost (including reasonable attorney's fees and disbursements)
or liability (including liabilities arising by reason of damages incurred by a
Party or other person) (collectively, "LOSSES") resulting from a breach by the
Partnership of any representation, warranty or covenant contained in this
Agreement; provided, however, that this indemnity shall not apply to the
KRF3/KR5 Transferor in its capacity as a limited partner of the Partnership,
with respect to which the provisions of the Limited Partnership Agreement shall
control.

                 (B)    Subject to the limitations set forth in Section 7.11 and
the provisions of Section 7.9, the Transferors shall indemnify and hold the
Partnership, Partnership Sub, BIR and the General Partner, and their respective
members, officers, directors and employees, harmless from and against any Losses
resulting from a breach by the Transferors, or either of them, of any
representation, warranty or covenant contained in this Agreement.

          7.11   LIMITATIONS ON INDEMNIFICATION. The indemnification provided
for in Section 7.10 shall be subject to the following limitations:

                 (A)    The Partnership may only seek recourse in respect of the
Transferors' indemnification obligation in Section 7.10(B) against the
Partnership Units issued to the KRF3/KR5 Transferor pursuant to this Agreement,
and the Partnership may not seek recourse against the direct or indirect members
of the Transferors or any of their assets or any of the other assets of the
Transferors for satisfaction of any liability of the Transferors under Section
7.10(B).

                 (B)    [Notwithstanding anything to the contrary in this
Agreement, the Transferors shall not be liable for any Losses based on a breach
or alleged breach of the representations and warranties contained in Sections
7.4, 7.5 and 7.6 unless all Losses arising out of such breaches or alleged
breaches shall exceed $250,000 in the aggregate, and then only to the extent of
such excess.]

                                  ARTICLE VIII

                            CASUALTY AND CONDEMNATION

          8.1    CASUALTY. If, prior to the Closing Date, any of the Properties
shall be materially damaged by fire or any other casualty with an estimated
repair or restoration costs in excess of [$2,500,000], the Partnership may by
written Notice delivered to the Transferors on or before the Closing Date, elect
either (i) to cause the transactions contemplated hereby to be restructured such
that the Partnership receives the Transferors' interest in only the remaining
Properties (or in entities which own only the remaining Properties) together
with, in lieu of the Transferors' interest in the Property

<Page>

                                                                              27

which was affected by the casualty, cash and/or other assets acceptable to the
Partnership having a value equivalent to that of such interest in exchange for
receipt by the KRF3/KR5 Transferor of Partnership Units having an equivalent
value (subject, however, to any consents of mortgagees or other third parties
necessitated by such restructuring); (ii) to continue this Agreement in effect
without abatement of the Consideration on account thereof; or (iii) to terminate
this Agreement (in which event the Partnership shall have no further rights and
obligations under this Agreement except for those which expressly survive such
termination).

          8.2    CONDEMNATION.

                 (A)    If, prior to the Closing, condemnation proceedings are
threatened in writing by an authorized governmental agency or commenced with
respect to (i) five percent (5%) or more of the rentable area of any Property,
(ii) so much of the parking facilities included in such Property that the
remaining parking facilities are legally inadequate to serve such Property or
(iii) so much of the Property that access to the remaining portion of the
Property is materially adversely affected, the Partnership may by written Notice
delivered to the Transferors on or before the Closing Date, elect either (i) to
cause the transactions contemplated hereby to be restructured such that the
Partnership receives the Transferors' interest in only the remaining Properties
(or in entities which own only the remaining Properties) together with, in lieu
of the Transferors' interest in the Property which was affected by the
condemnation, cash and/or other assets acceptable to the Partnership having a
value equivalent to that of such interest in exchange for receipt by the
KRF3/KR5 Transferor of Partnership Units having an equivalent value (subject,
however, to any consents of mortgagees or other third parties necessitated by
such restructuring); (ii) to continue this Agreement in effect without abatement
of the Consideration on account thereof; or (iii) to terminate this Agreement
(in which event the Partnership shall have no further rights and obligations
under this Agreement except for those which expressly survive such
termination)..

                 (B)    If a condemnation proceeding regarding any portion of
the Property is threatened or commenced prior to the Closing Date, the
Transferors shall promptly advise the Partnership of such event and shall keep
the Partnership reasonably informed as to any such proceeding. Between the date
hereof and the Closing Date, the Transferors shall not (i) agree to make any
conveyance in lieu of any such condemnation or (ii) make any conveyance in lieu
of any such condemnation without the Partnership's prior written consent.

                                   ARTICLE IX

                                     BROKER

          9.1    BROKERAGE INDEMNITY. The Transferors represent and warrant to
the Partnership that the Transferors have not dealt, and the Partnership
represents and warrants to the Transferors that neither it nor the Partnership
Sub has dealt, with any real estate broker, firm, salesperson or other similar
person or entity in connection with the transactions contemplated by this
Agreement. The Partnership shall indemnify and hold

<Page>

                                                                              28

the Transferors harmless from and against any and all claims, liabilities, costs
and expenses, including, without limitation, reasonable attorneys' fees and
disbursements, incurred in connection with any claims made against the
Transferors for brokerage commissions, and other fees or compensation made by
any broker, firm, salesperson or other entity with whom the Partnership may have
dealt in connection with this transaction. The Transferors shall indemnify and
hold the Partnership harmless from and against any and all claims, liabilities,
costs and expenses, including, without limitation, reasonable attorneys' fees
