                     licensed to do business and is in good standing in each
                     jurisdiction in which the nature of its business or the
                     ownership or leasing of its properties makes such
                     qualification or licensing necessary, other than in such
                     jurisdictions where the failure to be so qualified or
                     licensed, individually or in the aggregate, would not have
                     a Material Adverse Effect. True and correct copies of the

Sub or, to the  Knowledge of Lessee,  Management  or  Management  Sub, any other

               Leases (i) are legal, valid and binding obligations of Lessee,
               Management or Management Sub, as applicable, and to the Knowledge
               of Lessee, Management or Management Sub, as applicable, each

               Lessee or, to the Knowledge of Management, Management Sub or
               Lessee, as applicable, any other party thereto) under any Real
               Property Lease and no event has occurred which, with notice or
               the lapse of time, or both, would constitute a default (either on
               the part of Management, Management Sub or Lessee or, to the

               consummation of the Transactions will not result in any payment
               obligations under any of the Real Property Leases (whether
               pursuant to a "change in control" provision in the Real Property
               Leases or otherwise) to any Person other than Sunstone OP or its
               Subsidiaries, except as set forth on Schedule 3.1(j)(ii).

               the case may be, and the other party or parties named therein.
               Each such Space Lease is a legal, valid and binding obligation of

               alterations have not been completed as required pursuant to the

               the Knowledge of Lessee, Management or Management Sub, as
               applicable, no brokerage commissions or finder's fees that
               Lessee, Management or Management Sub is required to pay in excess
               of $20,000 with respect to the negotiation, renewal, extension or
               modification of any Space Lease set forth on Schedule 3.1(i)(iv)
               will be owing on the Closing Date. To the Knowledge of Lessee,
               Management or Management Sub, as applicable, there are no pending
               actions or proceedings instituted against Management, Management
               Sub, Lessee or any Lessee Subsidiary by any tenant under any

               legal, valid and binding obligation of Lessee, Management or
               Management Sub, as applicable, and to the Knowledge of Lessee,
               Management or Management Sub, as applicable, each other party

               have a Material Adverse Effect by any Person exists under any
               Section (v) Contract and none of Management, Management Sub or
               Lessee has received any written notice from any party to any
               Section (v) Contract claiming the existence of any default under
               such Section (v) Contract and no such Section (v) Contract has
               been assigned, transferred, hypothecated, pledged or encumbered
               by Management, Management Sub, Lessee or any Lessee Subsidiary.
               None of Management, Management Sub, Lessee, any Lessee Subsidiary
               or any of their Affiliates has any direct or indirect ownership
               interests in any Person providing goods or services under the
               Section (v) Contracts. To the Knowledge of Management, Management
               Sub or Lessee, as applicable, there are no pending actions or
               proceedings instituted against Management, Management Sub, Lessee
               or any Lessee Subsidiary by any party under any Section (v)
               Contracts. Each Section (v) Contract to be transferred to SHP and
               Management Newco pursuant to this Agreement is transferable
               without consent, other than as set forth on Schedule 3.1(j)(v)

               the date hereof, the Liquor Licenses for the businesses conducted
               by Management, Management Sub, Lessee and any Lessee Subsidiary,
               all of which are held in the names as set forth on Schedule
               3.1(j)(vi). The Liquor Licenses are legal, valid and binding
               obligations of Lessee, each Lessee Subsidiary, Management and
               Management Sub, as applicable, and to the Knowledge of Lessee,
               Management or Management Sub, as applicable, each other party
               thereto, enforceable in accordance with their terms. To the
               Knowledge of Management, Management Sub or Lessee, as applicable,
               no default except for defaults that would not have a Material
               Adverse Effect by any Person exists under the Liquor Licenses,
               and none of Management, Management Sub or Lessee has received any
               written notification of any material violation or alleged
               material violation of any applicable laws or regulations relating
               to the sale and service of alcoholic beverages which are
               outstanding and which have not been remedied. The Liquor Licenses
               are adequate for the operation of the business conducted by
               Management, Management Sub, Lessee and each Lessee Subsidiary
               consistent with past practice. All applicable state and federal

against Management,  Management Sub, Lessee or any Lessee Subsidiary or relating
to any of the  assets  of  Management,  Management  Sub,  Lessee  or any  Lessee

labor union or organization, and (iii) none of Management, Management Sub,
Lessee or any Lessee Subsidiary has closed any facility, effectuated any layoffs

foregoing which, individually or in the aggregate, would not have a Material
Adverse Effect.

               (m) Intellectual Property and Technology. Management, Management
Sub, Lessee and each Lessee Subsidiary own, or are licensed or otherwise have
the right to use in the manner currently being used, all patents, patent
registrations, patent applications, trademarks, trademark registrations,
trademark applications, tradenames, copyrights, copyright applications,
copyright registrations, franchises, URLs, domain names, permits and licenses
("Intellectual Property") used by Management, Management Sub and Lessee and
necessary to the operation of their respective businesses (the "Business
Intellectual Property"), subject to the terms of the respective franchise,
license and other agreements. Except as would not, individually or in the

third party. Except as would not,  individually or in the aggregate,  reasonably
be expected to have a Material  Adverse Effect,  all trademark  registrations of
each of Management,  Management Sub, Lessee and Lessee  Subsidiary are valid and
subsisting  and in full force and effect.  Each of Management,  Management  Sub,
Lessee or each Lessee  Subsidiary owns or is licensed or otherwise has the right
to use all of the processes, formulae, proprietary technology, inventions, trade
secrets, know-how, product descriptions and specifications ("Technology") in the
manner  currently  used by  Management,  Management  Sub,  Lessee or each Lessee
Subsidiary, except as would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect. Except as would not, individually or
in the  aggregate,  reasonably  be expected to have a Material  Adverse  Effect,
there have been no written  claims  (whether  private or  governmental)  against
Management,   Management   Sub   or   Lessee   asserting   the   invalidity   or
unenforceability  of its  ownership,  license  or other  right to use any of the
Technology. Except as would not, individually or in the aggregate, reasonably be
expected to have a Material  Adverse  Effect,  none of the rights of Management,
Management  Sub,  Lessee or any Lessee  Subsidiary to the Business  Intellectual
Property  or  the  Technology  will  be  impaired  in  any  way  by  any  of the

Intellectual Property licensed under franchise agreements,  such exception being
applicable only if Management, Management Sub, Lessee or such Lessee Subsidiary,
as the case may be,  shall  not be in  violation  of the  Intellectual  Property
provisions  of the  applicable  franchise  agreement,  and all of the  rights of
Management  and  Management  Sub  to  the  Business  Intellectual  Property  and
Technology  included in the Management Assets and the Basis Assets will be fully
enforceable  by  Management  Newco after the Closing  Date to the same extent as
such rights would have been  enforceable by Management or Management Sub, as the
case may be, before the Closing.

               Governmental Authority applicable to it, except where the failure
               to be in such compliance would not have, either individually or

                     (ii) Each of Management, Management Sub, Lessee and each
               Lessee Subsidiary has all licenses, permits, consents, approvals,

and except for matters that, individually or in the aggregate, would not have a
Material Adverse Effect, (i) each of Management, Management Sub, Lessee and each

Management,   Management  Sub,  Lessee  or  any  Lessee  Subsidiary  that  could
reasonably be expected to give rise to any liability under any Environmental Law
or result in costs  arising out of any  Environmental  Law;  (iii) no  judicial,
administrative,  or arbitral  proceeding  (including  any notice of violation or

Lessee  Subsidiary  of  complying  with  applicable  Environmental  Laws  or  of
obtaining,  renewing, or complying with all permits required under Environmental
Laws required under such laws; and (v) Management, Management Sub, Lessee, Alter
and Biederman have provided to SHP true and complete  copies of all reports with

Retirement Income Security Act of 1974, as amended and the rules and regulations
promulgated thereunder ("ERISA") ("Pension Plan"), any multiemployer plan, as
defined in Section 3(37) of ERISA (a "Multiemployer Plan") and any welfare plan
as defined in Section 3(1) of ERISA ("Welfare Plan")), whether or not any of the
foregoing is funded, insured or self-funded, written or oral, (i) sponsored or
maintained by Management, Management Sub, Lessee, any Lessee Subsidiary, or any
entity which, together with Management, Management Sub or Lessee, would be
treated as a single employer under Section 414 of the Code (each a "Controlled
Group Member") and covering any Controlled Group Member's active or former
employees (or their beneficiaries), (ii) to which any Controlled Group Member is
a party or by which any Controlled Group Member (or any of the rights,
properties or assets thereof) is bound or (iii) with respect to which any
current Controlled Group Member may otherwise have any material liability
(whether or not such Controlled Group Member still maintains such Employee
Plan). Each Employee Plan is listed in Schedule 3.1(p). With respect to the
Employee Plans:

                     (i) Except as disclosed in Schedule 3.1(p), no Controlled
               Group Member has any continuing liability under any Welfare Plan
               which provides for continuing benefits or coverage for any
               participant or any beneficiary of a participant after such

               Section 601 (et seq.) of ERISA, or under any applicable state
               law, and at the expense of the participant or the beneficiary of
               the participant.

                     (ii) Except as disclosed in Schedule 3.1(p), each Employee
               Plan which is not a Multiemployer Plan (and, to the Knowledge of
               Management, Management Sub or Lessee, as applicable, each
               Multiemployer Plan) complies in all material respects with the
               applicable requirements of ERISA and any other applicable law
               governing such Employee Plan, and each Employee Plan which is not
               a Multiemployer Plan (and, to the Knowledge of Management,
               Management Sub or Lessee, as applicable, each Multiemployer Plan)
               has at all times been administered in all material respects in
               accordance with all such requirements of law, and in accordance
               with its terms and the terms of any applicable collective
               bargaining agreement to the extent consistent with all such
               requirements of law. Each Employee Plan which is intended to be
               qualified has (A) received a favorable determination letter from
               the Internal Revenue Service stating that such Employee Plan
               meets the requirements of and is qualified under Section 401(a)
               of the Code, and that the trust associated with such Employee
               Plan is tax exempt under Section 501(a) of the Code, (B) an
               application for such determination is pending or (C) the remedial
               amendment period during which an application for such
               determination may be timely filed has not expired and such
               application will be timely filed before the expiration of such
               remedial amendment period, and to the Knowledge of Management,
               Management Sub or Lessee, as applicable, no event has occurred
               which would jeopardize the qualified status of any such plan or
               the tax exempt status of any such trust under Sections 401(a) and
               Section 501(a) of the Code, respectively, except in circumstances
               in which, individually or in the aggregate, the failure to so
               qualify or be tax exempt would not have a Material Adverse
               Effect.

                     (iii) No lawsuits, claims (other than routine claims for
               benefits) or complaints to, or by, any Person or Governmental
               Authority have been filed or are pending which, individually or
               in the aggregate, would have a Material Adverse Effect and, to
               the Knowledge of Management, Management Sub or Lessee, as
               applicable, there is no fact or contemplated event which would be
               expected to give rise to any such lawsuit, claim (other than
               routine claims for benefits) or complaint with respect to any
               Employee Plan that would have a Material Adverse Effect. Without
               limiting the foregoing, except in the case of the following
               clauses (1) through (6) as would not individually or in the
               aggregate have a Material Adverse Effect, the following are true
               with respect to each Employee Plan:

                         (1) all Controlled Group Members have filed or caused
                     to be filed every material return, report statement,
                     notice, declaration and other document required by any law
                     or governmental agency, federal, state and local
                     (including, without limitation, the Internal Revenue
                     Service and the Department of Labor) with respect to each
                     such Employee Plan, other than a Multiemployer Plan, each
                     of such filings has been complete and accurate in all
                     material respects and no Controlled Group Member has
                     incurred any material liability in connection with such
                     filings;

                         (2) all Controlled Group Members have delivered or

                     plan descriptions, returns, reports, schedules, notices,
                     statements and similar materials, including, without
                     limitation, summary plan descriptions and summary annual
                     reports, as are required under Title I of ERISA, the Code,
                     or both, and no Controlled Group Member has incurred any
                     material liability in connection with such deliveries;

                         (3) all contributions and payments with respect to
                     Employee Plans that are required to be made by a Controlled
                     Group Member with respect to periods ending on or before
                     the Closing Date (including periods from the first day of
                     the current plan or policy year to the Closing Date) have
                     been, or will be, made or accrued before the Closing Date
                     in accordance with the appropriate plan document, actuarial
                     report, collective bargaining agreements or insurance
                     contracts or arrangements or as otherwise required by ERISA
                     or the Code;

                         (4) with respect to each such Employee Plan, to the
                     extent applicable, Management, Management Sub and Lessee
                     have delivered to or have made available to Westbrook LLC
                     true and complete copies of (i) plan documents, or any and
                     all other documents that establish the existence of the

the contracts, commitments, books and records relating thereto, and shall use
commercially reasonable efforts to furnish such Persons all such documents and
such financial, operating and other data and information regarding such
businesses and Persons that are in the possession of such Person as the

including providing information and using reasonable best efforts to obtain all

<PAGE>


                                                                              39



in an aggregate amount in excess of $200,000 in connection with the obtaining of
all consents required to effect the Transactions. In case at any time after the
Closing Date any further action is necessary or desirable to transfer any of the
Management Assets, Basis Assets, Sunstone Stock or OP Units pursuant to the
terms of this Agreement, or to otherwise to carry out the terms of this
Agreement, the parties hereto and their respective Affiliates shall execute such
further documents (including assignments, acknowledgments and consents and other
instruments of transfer) and shall take such further action as shall be
necessary or desirable to effect such transfer and to otherwise carry out the
terms of this Agreement, in each case to the extent not inconsistent with
applicable law provided that Alter, Management and Management Sub are not
required to make any payments thereby and are reimbursed for all expenses and
costs incurred.

           4.5 Consents. Notwithstanding anything to the contrary contained in
this Agreement, to the extent that the sale, conveyance, transfer, assignment or
delivery or attempted sale, conveyance, transfer, assignment or delivery to SHP
or Management Newco of any Management Asset (including any assumed contract,
license or other agreement) is prohibited by applicable law or would require any
governmental or third-party authorization, approval, consent or waiver and such
authorization, approval, consent or waiver shall not have been obtained prior to
the Closing, this Agreement shall not constitute a sale, conveyance, transfer,
assignment or delivery, or an attempted sale, conveyance, transfer, assignment
or delivery thereof if any of the foregoing would constitute a breach of
applicable law or the rights of any third party; provided, however, that, except
to the extent that a condition to closing set forth herein, if any, relating to
the foregoing shall not be satisfied (in which case the Closing shall not occur
unless waived by Westbrook LLC), the Closing shall occur notwithstanding the
foregoing on account of such required authorization. Following the Closing,
Alter and Management shall use all reasonable best efforts to obtain promptly
such authorizations, approvals, consents or waivers provided, however, that
neither Alter nor Management shall be required to make any payments to obtain
such authorizations, approvals, consents or waivers. Pending or in the absence
of such authorization, approval, consent or waiver, Alter and Management shall
enter into reasonable and lawful arrangements which do not conflict with the
terms of any agreements relating to the Management Assets or the Basis Assets in
existence as of the date of this Agreement with SHP and/or Management Newco
designed to provide to SHP and/or Management Newco the benefits and liabilities
of use of such Management Assets and Basis Assets provided that Alter and
Management are not required to make any payments thereby and are reimbursed for
all expenses and costs incurred.

           4.6 Public Statements. Before any party to this Agreement or any
Affiliate of such party shall release any statements concerning this Agreement

dissemination thereof, such party shall cooperate with the other parties and
provide the other parties the reasonable opportunity to review and comment upon
any such statements and shall not release or permit release of any such
information without the consent of the other parties, which shall not be
unreasonably withheld.

           4.7 Notification of Certain Matters. Each party to this Agreement
shall give prompt notice to each other party of (i) the occurrence or
non-occurrence of any event, the occurrence or non-occurrence of which is likely
to cause any representation or warranty of such party contained



<PAGE>


                                                                              40



in this Agreement to be untrue or inaccurate at or prior to the Closing Date and
(ii) any failure of such party to comply with or satisfy any covenant, condition
or agreement to be complied with or satisfied by it hereunder; provided,
however, that the delivery of any notice pursuant to this Section 4.7 shall not
limit or otherwise affect any remedies available to the party receiving such
notice. No disclosure by any party pursuant to this Section 4.7 shall be deemed
to amend or supplement the disclosures set forth on the Schedules hereto or
prevent or cure any misrepresentations, breach of warranty or breach of
covenant.

           4.8 Employee Matters. (a) SHP shall cause Management Newco and Lessee
to promptly pay or provide when due all compensation and benefits earned or
accrued through or prior to the Closing Date as provided pursuant to the terms
of any compensation arrangements, employment agreements and employee or director
pension, welfare benefit or employee benefit plans, programs, arrangements and
policies in existence as of the date hereof for all employees (and former
employees) and directors (and former directors) of Management Newco and Lessee
and listed on any Schedule to this Agreement. SHP shall cause Management Newco
and Lessee to pay promptly or provide when due all compensation and benefits
required to be paid pursuant to the terms of any individual agreement with any
current or former employee or director in effect and listed on Schedule 4.8(a)
to this Agreement. Nothing in this Agreement shall require the continued
employment of any Person or prevent SHP and/or Management Newco or Lessee from
taking any action or refraining from taking any action which Management or
Lessee could take or refrain from taking prior to the Closing Date.
Notwithstanding the above, except as set forth on Schedule 4.8(a), SHP shall
cause Management Newco and Lessee to pay compensation to any key employee in
accordance with compensation parameters agreed to by Alter and Westbrook LLC and
as provided in the LLC Agreement and this Agreement.

               (b) After the Closing Date, all employees of Management or Lessee
who continue employment with SHP and/or Management Newco or Lessee shall, at the
option of SHP, either continue to be eligible to participate in an "employee
benefit plan," as defined in Section 3(3) of ERISA, of Management or Lessee
which is, at the option of SHP, continued by SHP, Management Newco or Lessee, or
alternatively shall be eligible to participate in any "employee benefit plan,"
as defined in Section 3(3) of ERISA, established, sponsored or maintained by
SHP, Management Newco or Lessee after the Closing Date; provided that the
employee benefits immediately after the Closing shall be no less favorable to
the employees of Management and Lessee in the aggregate than the employee
benefits immediately prior to the Closing; and provided further that nothing
contained in this Section 4.8(b) shall in any way limit the ability of SHP,
Management Newco or Lessee to modify any employee benefits in any respect
following the Closing. With respect to each such employee benefit plan not
formerly maintained by Management or Lessee, service with Management, Lessee or
any Controlled Group Member (as applicable) shall be included for purposes of
determining eligibility to participate, vesting (if applicable) and entitlement
to and level of benefits (other than accrual of benefits under any defined
benefit plan) and all pre-existing condition exclusions and waiting periods
shall be waived and expenses incurred by any employee for deductibles and
copayments in the portion of the year prior to the date employee first becomes a
participant in such employee benefit plan shall be credited to the benefit of
such employee under such employee benefit plan for the year in which the
employee's participation commences.

               (c) With respect to any accrued but unused vacation time to which
any Transferred Employee is entitled pursuant to the vacation policy applicable
to such Employee immediately prior to the Closing (the "Vacation Policy"), SHP
shall cause Management Newco and Lessee to allow such Employee to use such
accrued vacation; provided, however, that if SHP deems it necessary to disallow
such employee from taking such accrued vacation, SHP shall cause Management
Newco and Lessee to be liable for and pay in cash to each such Employee an
amount equal to such vacation time in accordance with terms of the Vacation
Policy.

           4.9 Transfer Taxes. SHP shall bear all share transfer taxes,
recording fees and other sales, transfer, use, purchase, stamp or similar taxes
resulting or arising out of the Transactions.

           4.10 Injunctions or Restraints. In the event that there exists at or
prior to Closing (i) any injunction, restraining order or other decree of any
nature of any court of competent jurisdiction or other Governmental Authority
that is in effect that restrains or prohibits the consummation of any of the
Transactions or (ii) any action taken, or any statute, rule, regulation or order
enacted, entered or enforced, which makes the consummation of the Transactions
illegal, each party to this Agreement shall use their reasonable commercial
efforts to have any such injunction, order, decree, action, statute, rule or
regulation vacated or declared inapplicable.

           4.11 Certification of United States Status of Alter and Biederman.
Each of Alter and Biederman shall deliver as of Closing to SHP a certificate,
duly executed and acknowledged, certifying that each is not a foreign person, as
defined in Treasury regulation section 1.1445- 2(b)(2)(i), such certification in
the form similar to that described in Treasury regulation section
1.1445-2(b)(2)(iii)(A) or otherwise meeting the requirements of Treasury
regulation section 1.1445-2(b)(2).

           4.12 Spousal Claims. Alter agrees to maintain all Lessee Stock, OP
Units and other property to be contributed to SHP pursuant to Section 2.1 hereof
free from all potential spousal claims including election share, community
property interest or otherwise.

           4.13 Tax Matters. (a) Guaranty or Indemnity. To enable Riverside,
Management, Alter and Biederman (the "Contributors") at their election to defer
the recognition of gain for federal income tax purposes resulting from their
contribution to SHP pursuant to Section 2.1 hereof at Closing, or at any time
subsequent thereto in accordance with the terms hereof, SHP agrees to permit,
and to cause its Subsidiaries to permit, the Contributors to guarantee at the
Contributors' option (or indemnify SHP or its Affiliates at the Contributors'
option) at or any time after the Closing, upon the request of any Contributor,
indebtedness of SHP or its Subsidiaries in an amount not to exceed $10.5 million
to be allocated among such Contributors as set forth in Schedule 4.13. Such
guarantee or indemnity will be with respect to debt chosen by the Contributors,
subject to the consent of the Westbrook Entities with respect to which debt
shall be guaranteed or indemnified, which consent shall not be unreasonably
withheld, and shall guarantee or indemnify the bottom portion of such debt. The
Westbrook Entities hereby consent to the guarantee by the Contributors of the
debt to be provided by PaineWebber in connection with the Merger and any
indebtedness that replaces such indebtedness.

               (b) Representatives. For purposes of this Section 4.13(b), the
Contributors shall designate Alter as their representative and if Alter is
unavailable, Biederman as their representative, for purposes of coordinating any
guarantees, indemnities, or other items set forth in such sections.

               (c) Allocation Method. SHP covenants that the "traditional
method" (without curative allocations), as defined in Treas. Reg. ss.1-704-3(b),
of allocating income, gain, loss and deduction to account for the variation
between the fair market value and adjusted basis of the property for federal

           4.14 Tax Filing. The parties to this Agreement agree to report the
Transactions in the manner described in Section 2.1 hereto for purposes of
filing any and all Tax and information returns and to take and defend positions
consistent therewith in all dealings with the Internal Revenue Service, and all
other government authorities (except upon a decision by a final taxing authority
in which case any returns shall be amended to be consistent with such decision
and any future returns shall be filed consistently with such decision).

           4.15 Certain Obligations. (a) SHP will use its reasonable best
efforts to secure the release of each of Alter and Biederman from their
respective obligations incurred following the Closing under the guarantees and
indemnities listed in Schedule 4.15(a), which release may be accomplished (at
SHP's election) by issuances of guarantees or indemnities by SHP with respect to
such obligations or the assumption by SHP of such obligations. To the extent
Alter and Biederman are not released from such post-Closing obligations, SHP and
Management Newco shall, jointly and severally, indemnify and hold Alter and
Biederman, and their respective Affiliates, heirs, executors, successors and
assigns, harmless for all Losses suffered or incurred by either of them under
such obligations.

               (b) Effective as of the Closing, all arrangements between any of
the Alter Entities, Biederman, Lessee, Management or Management Sub or any
Affiliate of the foregoing, other than Sunstone and Sunstone's Subsidiaries
(collectively the "Alter/Biederman Parties"), on the one hand, and Sunstone or
any of Sunstone's Subsidiaries, on the other hand, shall be terminated with no
further obligations or Liabilities by Sunstone or any of Sunstone's Subsidiaries
thereunder, except for the agreements listed on Schedule 4.15(b) (which shall
not be terminated) and the obligations or liabilities incurred thereunder
following the Closing. Each of the Alter/Biederman Parties severally represents
to SHP that no amounts are owing or payable by it or him to Sunstone or any
Sunstone Subsidiary under any agreement or arrangement between any of the
Alter/Biederman Parties, on the one hand, and Sunstone or any of Sunstone's
Subsidiaries, on the other hand, whether or not such agreement or arrangement
shall be terminated pursuant to this section. Notwithstanding the termination of
the agreements and arrangements referred to in the second preceding sentence,
the Alter/Biederman Parties shall retain all obligations and Liabilities to
Sunstone and its Subsidiaries under all agreements and arrangements between the
Alter/Biederman Parties, on the one hand, and Sunstone and its

Subsidiaries, on the other hand, incurred before the Closing, and shall
indemnify SHP for all Losses incurred by it in connection with such obligations
and Liabilities. Except with respect to obligations or Liabilities incurred
following the Closing under the agreements listed on Schedule 4.15(a) or
Schedule 4.15(b), any obligations or Liabilities under this Agreement or the
Implementing Agreements or payment obligations under the Lessee Line of Credit,
the Alter/Biederman Parties hereby release and discharge and indemnify and hold
harmless SHP, on behalf of Sunstone and Sunstone's Subsidiaries, and their
successors and assigns from all actions, causes of action, suits, debts, dues,
sums of money, accounts, claims and demands owed by Sunstone or any of
Sunstone's Subsidiaries to any of the Alter/Biederman Parties, by reason of any
matter, cause, contract, course of dealing or thing whatsoever arising during,
or in respect of, the period on or before the Closing.

               (c) All amounts due and payable by Management and Lessee under
the agreement set forth on Schedule 3.1(v) will be Assumed Management
Liabilities (in the case of amounts due and payable by Management) or a
Liability of Lessee after the Closing (in the case of amounts due and payable by
Lessee), and Alter agrees to reimburse Management and Lessee for 44.5% of such
amounts at or prior to the Closing.

                                   ARTICLE VI

                 COVENANTS AND AGREEMENTS WITH RESPECT TO LESSEE
                 -----------------------------------------------

           6.1 Recapitalization of Lessee. (a) Lessee hereby agrees to take all
necessary action required to be taken by it to recapitalize its capital
structure (the "Recapitalization") so that immediately prior to the Closing the
outstanding capital stock of Lessee shall consist of 1,000 shares of Lessee
Class A Voting Stock and 1,000 shares of Lessee Class B Non-Voting Stock, 800
shares of each such class to be held by Alter and 200 shares of each such class
to be held by Biederman. All such actions (and documentation related thereto)
shall be reasonably satisfactory to the Westbrook Entities.

               (b) Each of Alter and Biederman hereby agrees to take all
necessary action required to be taken by such Person, and to cause Lessee to
take all necessary action to effect the Recapitalization. All such actions (and
documentation related thereto) shall be reasonably satisfactory to the Westbrook
Entities.

               (c) To the extent the Recapitalization shall not be effected on
terms and in a manner reasonably satisfactory to the Westbrook Entities, (i)
Lessee shall not effect the Recapitalization and (ii) all of the outstanding
Lessee Stock shall be contributed to SHP by the Alter Entities and Biederman
pursuant to Section 2.1 (without receipt of any additional consideration
(including any additional Capital Account credit)).

           6.2 Governance. Each of Alter, any of his Affiliates who owns
Securities and SHP (collectively, the "Lessee Stockholders"), hereby covenants
and agrees, from and after the Closing until exercise of the Option, to comply
with the following provisions related to the governance of Lessee:

               (a) Election of Directors. Each Lessee Stockholder hereby agrees
that such Lessee Stockholder will vote all of the Securities beneficially owned
by it entitled to vote in the



<PAGE>


                                                                              47



election of members of the board of directors of Lessee (the "Lessee Board") so
as to elect and to continue in office a Lessee Board consisting of three
designees of SHP ("SHP Directors") and one designee of Alter (the "Alter
Director"). For so long as Alter is employed by SHP, Alter shall be the Alter
Director. If Alter is no longer an employee of SHP, another individual
acceptable to SHP may be selected by Alter to serve as the Alter Director
instead of Alter. SHP agrees to vote all of the voting Securities beneficially
owned by it so as to elect the Alter Director to the Lessee Board. If at any
time SHP shall notify Alter it desires to remove any SHP Director, with or
without cause, Alter agrees to vote all of such voting Securities beneficially
owned or held by him as to remove such SHP Director.

               (b) Lessee Board Meetings. Meetings of the Lessee Board, annual,
regular and special, shall be held at the principal office of Lessee or other
place as may from time to time be fixed by resolution of the Lessee Board.
Regular meetings of the Lessee Board shall be held at such times as may from
time to time be fixed by resolution of the Lessee Board, and no notice (other
than the resolution) need be given as to any regular meeting. Special meetings
may be held at any time upon the call of any two members of the Lessee Board, by
oral, telephonic or facsimile notice (or notice given by other means of
electronic transmission (including electronic mail)) duly given or sent at least
one day, or by written notice sent by express mail at least two days, before the
meeting to each member of the Lessee Board. Any action required or permitted to
be taken at any meeting of the Lessee Board may be taken without a meeting if a
written consent thereto is signed by all members of the Lessee Board. Lessee
shall reimburse each member of the Lessee Board for his or her reasonable
expenses in connection with attending any meeting of the Lessee Board.

               (c) Lessee Board Voting. A majority of incumbent members of the
Lessee Board shall be necessary to constitute a quorum for the transaction of
business at any Lessee Board meeting. The Lessee Board shall have the general
powers and duties typically vested in the board of directors of a corporation.
All actions or decisions of the Lessee Board shall require approval of a
majority of the members of the Lessee Board; provided that, so long as Lessee is
a Subsidiary of SHP, it will remain subject to the provisions of the LLC
Agreement applicable to Subsidiaries of SHP.

           6.3       Restrictions on Transfers and Issuances.

               (a) Limitations on Transfer. Alter hereby agrees that he will
not, and will not permit or cause any of his Affiliates (including Alter SHP
LLC) to, from and after the Closing, without the prior written consent of SHP,
Transfer or agree to Transfer record or beneficial ownership of any Securities.
To the extent SHP consents to a Transfer of Securities by Alter or any of his
Affiliates (including Alter SHP LLC) who holds Securities, Alter agrees that all
consideration paid or payable to him or such Affiliate with respect to any such
Transfer shall be paid directly to SHP, and Alter will direct any purported
transferee of such Securities to pay such proceeds or consideration directly to
SHP. To the extent any such proceeds or consideration are paid directly to Alter
or any of his Affiliates, Alter agrees to immediately forward any such
consideration to SHP.

                                                                              48



               (b) Effect of Void Transfers. In the event of any purported
Transfer of any Securities in violation of the provisions of this Article VI,
such purported Transfer shall be void and of no effect and Lessee shall not give
effect to such Transfer.

               (c) Rights to Dividends and Distributions. Alter agrees that
Lessee shall pay, and Lessee agrees to pay, directly to SHP all dividends and
other distributions after the Closing and prior to the exercise of the Option,
whether cash or non-cash, with respect to any Securities beneficially owned by
it. To the extent any such dividends or other distributions are paid directly to
Alter or any of his Affiliates (including Alter SHP LLC), Alter agrees to, or to
direct any such Affiliate to, immediately forward any such dividends and
distributions to SHP.

           6.4 Option. In the event that (a) the Alter Director fails to vote in
favor of any action approved by a majority of the Lessee Board (a "Failure to
Approve") or (b) Alter ceases to be an employee of SHP for any reason (a
"Termination"), SHP shall have the right, at any time to require Alter or any of
Alter's Affiliates holding Securities to sell to SHP all of the Securities owned
by him or it, as the case may be, and Alter shall have the obligation to sell,
or cause such Affiliate to sell, such Securities to SHP, free and clear of all
Liens (the "Option") for an aggregate cash purchase price of $1 (the "Option
Price"). The Option may be exercised by SHP at any time after a Failure to
Approve or a Termination by delivery of written notice to Alter (the "Exercise
Notice"). Unless otherwise agreed upon by SHP and Alter, the closing of the
purchase of the Securities shall occur at the offices of SHP on the third
business day after delivery of the Exercise Notice. At the closing, Alter shall,
or shall cause his Affiliate to, deliver to Lessee all stock certificates
representing the Securities together with blank stock powers or such other
assignments as reasonably requested by SHP, and SHP shall pay Alter or his
designee the Option Price. In addition, in the event Alter or his Affiliate
fails to deliver the stock certificates, stock powers or assignments reasonably
requested by SHP as set forth herein, SHP may deliver the Option Price to Alter
and upon such delivery, execute and deliver, as the attorney in fact for the
Alter Member, such stock powers and required assignments, as well as
documentation instructing Lessee to issue replacement stock certificates. Such
power of attorney is coupled with an interest and shall survive the insolvency,
bankruptcy and dissolution of Alter or his Affiliate. SHP, on the one hand, and
Alter and his Affiliates on the other hand, shall each pay their own expenses in
connection with the exercise of the Option.

           6.5 Additional Securities Subject to Agreement. Each Lessee
Stockholder agrees that any other Securities which it shall hereafter acquire by
means of a stock split, stock dividend, distribution, exercise of stock options,
or otherwise shall be subject to the provisions of this Article VI to the same
extent as if held on the date hereof.

           6.6 No Conflicting Agreements. Neither of the Lessee Stockholders
shall enter into, nor shall they permit Lessee or any Affiliate thereof to enter
into, directly or indirectly, any stockholder agreement or other arrangement of
any kind with any Person with respect to any Securities which is inconsistent
with the provisions of this Article VI or which may impair its ability to comply
with this Agreement.

           6.7 Survival. The provisions of this Article VI shall survive the
Closing and continue until terminated by exercise of the Option by SHP.

                                   -----------

           7.1 Termination Events. This Agreement may be terminated and the
Transactions may be abandoned at any time prior to the Closing:

               (a) by mutual written consent of Alter and Westbrook LLC;

               (b) by Westbrook LLC, upon a breach of any representation,
warranty, covenant, obligation or agreement on the part of Management, Lessee,
any Alter Entity or Biederman set forth in this Agreement, in any case such that
the conditions set forth in Section 5.2(a) or 5.2(b), as the case may be, are
not satisfied or would be incapable of being satisfied within 30 days after the
giving of written notice to Alter;

               (c) by Alter, upon a breach of any representation, warranty,
covenant, obligation or agreement on the part of any of the Westbrook Entities
such that the conditions set forth in Section 5.3(a) or 5.3(b) are not satisfied
or would be incapable of being satisfied within 30 days after the giving of
written notice to Westbrook LLC; or by Biederman, upon a breach of any
representation, warranty, covenant, obligation or agreement on the part of any

5.4(b) are not satisfied or would be incapable of being satisfied within 30 days
after the giving of written notice to Westbrook LLC;

               (d) by any of Alter or Westbrook LLC if any court of competent
jurisdiction in the United States shall have issued a final and unappealable
permanent injunction, order, judgment or other decree (other than a temporary
restraining order) restraining, enjoining or otherwise prohibiting the
consummation of the Transactions, provided that the party seeking to terminate
this Agreement under this clause (d) is not then in material breach of this
Agreement and provided, further, that the right to terminate this Agreement
under this clause (d) shall not be available to any party who shall not have
used reasonable commercial efforts to avoid the issuance of such order, decree
or ruling; and

               (e) by any of Alter, Biederman or Westbrook LLC if the Merger
Agreement or the Partnership Merger Agreement shall have been terminated in
accordance with its terms.

                                                                              50



           7.2 Fees and Expenses.

               (a) In the event that this Agreement is terminated by any party
prior to Closing, all documented out-of-pocket fees and expenses (including
reasonable attorney's fees and costs relating thereto) incurred by each of the
Alter Entities, Biederman, the Westbrook Entities and their respective
Affiliates (including SHP) in connection with this Agreement and the
Transactions (the "Expenses") shall be paid by SHP, but only to the extent SHP
receives any payments pursuant to Section 7.2 of the Merger Agreement (the
"Merger Agreement Payment"). To the extent the Merger Agreement Payment is not
sufficient to pay all the Expenses incurred by the parties hereto, Westbrook LLC
and its Affiliates, on the one hand, and Alter and his Affiliates, on the other
hand, shall receive a pro rata portion of the Merger Agreement Payment based on
the actual Expenses incurred by the Westbrook Entities and the Alter Entities,
respectively. To the extent the Merger Agreement Payment exceeds all Expenses,
any remaining portion of the Merger Agreement Payment will be distributed 88.5%
to the Westbrook Entities (the "Westbrook Payment") and 11.5% to Alter.

               (b) Subject to the terms and conditions of this Section 7.2(b),
to the extent the Westbrook Entities receive a Westbrook Payment, the Westbrook
Entities, jointly and severally, agree to use 30% of the Westbrook Payment (the
"Section 7.2 Price") in cash to purchase, and Alter agrees to sell, or to cause
one or more of his Affiliates to sell, a number of shares of Lessee Stock
representing the Section 7.2 Percentage (as defined below) of all issued and
outstanding Lessee Stock as soon as practicable following receipt of the
Westbrook Payment by the Westbrook Entities (the "Section 7.2 Purchase"). The
Section 7.2 Purchase shall be subject to the terms and conditions hereof, other
than the provisions of Article II, Sections 3.3, 3.5, 4.13, 4.14, 4.15, 5.1(c),
5.1(d), 5.4, 5.5, Article VI and Sections 8.3, 8.5, 8.8(d) and 8.9 and such
other modifications to this Agreement as may be necessary to reflect the Section
7.2 Purchase rather than the closing of all the transactions contemplated by
this Agreement. In addition, (i) references to "Biederman" in Sections 5.2, 5.3,
8.1 and 8.2 shall be disregarded in connection with the Section 7.2 Purchase,
(ii) each dollar amount referenced in Sections 8.8(a) and 8.8(b) shall be deemed
to be replaced by the Section 7.2 Percentage multiplied by such amount and (iii)
the consummation of a Section 7.2 Purchase shall be conditioned on the
Recapitalization having not been consummated or, if consummated, the
Recapitalization having been rescinded. As used herein, the "Section 7.2
Percentage" shall be equal to the Section 7.2 Price divided by $16 million, but
in no event shall the Section 7.2 Percentage exceed 37.5%, and in no event shall
the Section 7.2 Price exceed $6 million.

               (c) Notwithstanding anything to the contrary contained herein, in

           8.6 Third-Party Claims. If a claim by a third party is made against

indemnity with respect thereto under this Article, such indemnified Person shall
promptly notify the indemnifying Person in writing of such claims setting forth
such claims in reasonable detail, provided that failure of such indemnified
Person to give prompt notice as provided herein shall not relieve the
indemnifying Person of any of its obligations hereunder, except to the extent
that the indemnifying Person is materially prejudiced by such failure. If the
indemnifying Person acknowledges in writing its obligation to indemnify the
indemnified Person against any Losses that may result from such third party
claim, then the indemnifying Person shall have 20 days after receipt of such
notice to undertake, through counsel of its own choosing, subject to the
reasonable approval of such indemnified Person, and at its own expense, the
settlement or defense thereof, and the indemnified Person shall cooperate with
it in connection therewith; provided, however, that the indemnified Person may
participate in such settlement or defense through counsel chosen by such
indemnified Person, provided that the fees and expenses of such counsel shall be
borne by such indemnified Person. The indemnifying Person shall not settle any
claim or consent to the entry of any judgment without the prior written consent
of the indemnified Person, unless (i) such settlement or judgement includes as
an unconditional term thereof the giving by the claimant of a release of the
indemnified Person from all Liability with respect to such claim and (ii) such
settlement or judgement does not involve the imposition of equitable remedies or
the imposition of any material obligations on such indemnified Person other than
financial obligations for which such indemnified Person will be indemnified
hereunder. If the indemnifying Person shall assume

the defense of a claim, the fees of any separate counsel retained by the
indemnified Person shall be borne by such indemnified Person unless there exists
or is reasonably likely to exist a conflict of interest between them as to their
respective legal defenses (other than one that is of a monetary nature) in the
reasonable judgment of the indemnified Person, in which case the indemnified
Person shall be entitled to retain one law firm as its separate counsel, the
reasonable fees and expenses of which shall be reimbursed as they are incurred
by the indemnifying Person. If the indemnifying Person does not notify the
indemnified Person within 20 days after the receipt of the indemnified Person's
notice of a claim of indemnity hereunder that it elects to undertake the defense
thereof and that it acknowledges its obligation to indemnify the indemnified
Person against any Losses that may result from such claim, the indemnified
Person shall have the right to contest, settle or compromise the claim in a
reasonable manner, and the indemnifying Person shall cooperate with in
connection therewith, but the indemnified Person shall not thereby waive any
right to indemnity therefor pursuant to this Agreement.

warranty or pre-closing agreement pursuant to Section 3.6; provided, however,
that such obligation to indemnify and hold harmless shall not terminate with
respect to any item as to which the Person to be indemnified shall have, before
the expiration of the applicable period, previously made a claim by delivering a
written notice (stating in reasonable detail the basis of such claim) to the
indemnifying party.
