Item 3.     Source and Amount of Funds or Other Consideration.

          The  source  of  funds  for  the  purchases  reported  by  each of the
Reporting Persons herein was working capital of each such Reporting Person.  The
total amount of funds used by certain Reporting  Persons to purchase  14,072,190

for  certain  interests  in real  properties  valued at  $13,967,095  which were
contributed to the Trust by RDVI pursuant to the Transactions (defined below).

Item 4.     Purpose of Transaction.

          As described in proxy materials sent to the Trust's shareholders on or
about July 10, 1998 and filed with the  Securities  and Exchange  Commission  on
Schedule  14A,  the  purpose  of the  acquisition  of the  Common  Shares by the
Reporting  Persons was to acquire control of the Trust and for  investment.  The
Reporting  Persons purchased the 16,061,238 Common Shares in connection with the
consummation of certain  transactions  contemplated by a Contribution  and Share
Purchase  Agreement,  dated as of April 15, 1998, among the Trust,  Mark Centers
Limited Partnership and certain entities  affiliated with RD Capital,  Inc. (the
"Transactions").  The Transactions were formally approved by the shareholders of
the Trust on August  12,  1998,  which is the same  date as the  closing  of the
Transactions (the "Closing").  Confirmation of the exact number of Common Shares
owned by each Reporting  Person was a post-closing  item which was determined on
September 3, 1998.

          Each of the  Reporting  Persons  intends to review its  holdings  with
respect to the Trust on a continuing  basis.  Depending on each of the Reporting
Persons'  evaluation  of the Trust's  business  and  prospects,  and upon future
developments (including,  but not limited to, market prices of the Common Shares
and  availability  and  alternative  uses of funds, as well as conditions in the
securities  markets and general economic and industry  conditions),  each of the
Reporting  Persons  may acquire  other  securities  of the Trust,  sell all or a
portion  of its Common  Shares or other  securities  of the Trust,  now owned or
hereafter acquired,  provided,  however,  that each of the Reporting Persons has
agreed  pursuant to the agreements  described in Exhibit 99.3,  99.4 and 99.5 in
Item 7 below that prior to 18 months  after the Closing (12 months with  respect
to the RDC  Funds)  it shall  not  sell,  transfer,  convey,  assign,  pledge or
hypothecate any of the Common Shares beneficially owned by such Reporting Person
reported herein. See Item 5(b).

          Other than as described  above,  each of the Reporting  Persons has no
present  plans or  proposals  which  relate  to, or would  result in, any of the
matters  enumerated  in  paragraphs  (b) through  (j),  inclusive,  of Item 4 of
Schedule 13D.  Each of the  Reporting  Persons may, at any time and from time to
time, review or reconsider its position with respect to the Trust, and formulate
plans or proposals with respect to any such matters.

Item 5.     Interest in Securities of the Issuer.

(a) As of the close of business on  September  3, 1998,  the  Reporting  Persons
owned,  within  the  meaning  of Rule  13d-3  under  the  Exchange  Act,  in the
aggregate,  16,061,238 Common Shares. The Reporting Persons beneficially own, in
the aggregate,  approximately  63.2% of the Common Shares issued and outstanding

13d-3 under the Exchange Act,  2,266,667 Common Shares or 8.9% of the issued and
outstanding  Common  Shares.  Each of Dworman  and  Bernstein,  as the  managing
members  of the  General  Partner,  may be deemed  the  beneficial  owner of the
16,061,238  Common  Shares held by the RDC Funds.  Rothschild,  as sole managing
member of Five  Arrows,  may be deemed  the  beneficial  owner of the  2,266,667
Common Shares held by Five Arrows.  Charlesbank,  by virtue of its  relationship
with Harvard  described under Item 2 (c) above, may be deemed to have beneficial
ownership of the 2,000,000 Common Shares beneficially owned by Harvard.

          (b) Through the date which is 18 months after the Closing, each of the
RDC Funds has the sole power to dispose of the Common  Shares owned by it, which
power may be exercised  by the General  Partner.  Beginning  after such 18 month
period each of the limited  partners of the RDC Funds  (i.e.,  the LP  Reporting
Persons) have the sole right to dispose of 1/3 of the Common Shares allocated to
it which would  otherwise be  distributable  to such limited partner if such RDC
Fund were  liquidated,  and such limited partners have the sole right to dispose
of an  additional  1/3  of  such  Common  Shares  on the  24th  and  30th  month
anniversary of the Closing.

          Each  limited  partner of the RDC Funds has the sole power to vote the
Common Shares  allocable to it which would  otherwise be  distributable  to such
limited  partner if such RDC Fund were  liquidated.  With respect to Five Arrows
such voting power also may be exercised by Rothschild.

          (c) The RDC Funds  purchased  a then  indeterminable  number of Common
Shares from the Trust on August 12, 1998, in connection  with the  Transactions.
On September 3, 1998, the exact number of shares  purchased by the RDC Funds was
determined to be 14,072,190.  In consideration  for such Common Shares,  the RDC
Funds paid $7.50 per Common Share for a total of $105,541,425.  In addition, the
1,989,048  Common  Shares  received in exchange  for  interests  in certain real
property  contributed  to the Trust by RDVI were  valued  at $7.022  per  Common
Share, for a total of $13,967,095.

          (d) Not Applicable.

          (e) Not Applicable.


Item 6.   Contracts, Arrangements,  Understandings or Relationships with respect
          to Securities of the Issuer.

          Pursuant to the terms of the partnership  agreements of the RDC Funds,
each RDC  Fund has  granted  to its  limited  partners  (i.e.  the LP  Reporting
Persons) a proxy to exercise all of the voting  rights of a  shareholder  of the
Trust  with  respect  to the Common  Shares  owned by such RDC Fund which  would
otherwise  be  distributable  to the  limited  partners  if such RDC  Fund  were
liquidated.  There are no agreements among any of the LP Reporting  Persons with
respect to voting  such  Common  Shares as a group.  Therefore,  other than with
respect  to  the  initial  acquisition  of the  Common  Shares  pursuant  to the
Transactions,  the LP  Reporting  Persons

transaction that results in the realization of UBTI without the consent of all
of the Limited Partners.

                  SECTION 3.4.  Expenses.

                  (a) The Partnership shall be responsible for and shall pay all
Partnership Expenses except to the extent that there are not sufficient funds of
the Partnership to pay such Partnership Expenses or the General Partner shall
determine that it is not in the best interest of the Partnership to pay such
Partnership Expenses. As used herein, the term "Partnership Expenses" means all

         expenses reimbursed to the General Partner in connection with any
         litigation brought by or on behalf of any Limited Partner against the
         General Partner shall not constitute Partnership Expenses and the
         General Partner shall be obligated to repay any reimbursement for such
         expenses pursuant to this Section 3.4(a) if such litigation is resolved
         against the General Partner), but nothing herein shall preclude the

         therewith, as to which neither the General Partner nor any of its
         Affiliates is entitled to indemnification pursuant to the provisions of
         Section 8.1 hereof or otherwise shall not constitute Partnership
         Expenses for which either the General Partner or any of its Affiliates
         shall be entitled to be paid or reimbursed pursuant hereto and the
         General Partner and any of its Affiliates shall be required to repay

                  (b) Any action which may be taken at any meeting of the

                                   ARTICLE IV

                    INVESTMENTS AND INVESTMENT OPPORTUNITIES

                  SECTION 4.1.  Investments Generally.

                  (a) Subject to Section 3.3, the Investments to be acquired by
the Partnership shall be selected by the General Partner in its sole discretion.
Except for the Shares, the Partnership shall not purchase any single Investment
the capitalized acquisition cost of which (excluding the amount of any
acquisition financing) exceeds 20% of the Capital Commitments of the
Partnership. However, the Partnership may invest a larger percentage of its
Capital Commitments in a single Investment if, in the opinion of the General
Partner, such Investment is reasonably likely to be reduced to 20% of the
Partnership's Capital Commitments within twelve months by attracting suitable
co-investors or through a financing.

                  (b) The General Partner shall not, without the consent of the
Required Partners, cause the Partnership to acquire any Investment after the
Full Investment Date other than (i) any Investment as to which a Drawdown Notice
was given prior to the Full Investment Date or (ii) any Investment which then is
or will become part of, adjacent to or ancillary to any then existing Investment
of the Partnership.

                  (c) The General Partner shall not, without the consent of the
Required Partners, cause the Partnership at any time to apply proceeds from the
sale of any Investment to the acquisition by the Partnership of any other
Investment other than any Investment which then is or will become part of,
adjacent to or ancillary to any then existing Investment of the Partnership.

                  SECTION 4.2. Restriction on Investments by the General
Partner. Prior to the time at which the Remaining Capital Commitments of the
Limited Partners are equal to or less than One Million Dollars ($1,000,000) the
General Partner or any of its Affiliates may not make an Equity Investment (as
defined below) for its own account without first having obtained the consent of
the Required Partners. "Equity Investment" means (i) any direct ownership
interest in real estate assets or (ii) any debt security, loan or other similar
obligation having equity participation or conversion rights with respect to
interests referred to in clause (i) above. The Partners acknowledge that Ross
Dworman, a member of the General Partner, may, on behalf of family trusts and
their affiliates, be involved in various

                                       20

720885.2


<PAGE>



investments, which shall not conflict with the investment
objectives of the Partnership.

                  SECTION 4.3. Permitted Investments. Nothing in Section 4.2,
4.3, 4.5 or any other provision of this Agreement shall limit the right of the
General Partner or any of its Affiliates, and each of them shall be permitted
without first having consulted with any Limited Partner (a) to hold, improve,
develop, construct, maintain, operate, manage, lease, mortgage, sell, exchange,
dispose of and otherwise deal in and exercise control over any assets owned or
managed directly or indirectly by the General Partner or any Affiliate thereof
as of the date hereof (or where the impending ownership or management thereof
has been heretofore disclosed in writing to the Limited Partners) or where such
assets are hereafter acquired pursuant to the provisions of this Section 4.3 (b)
to acquire any improved or unimproved land adjacent or contiguous (but for
rights-of-way, easements, strips, gores or similar separations between
properties) to any real estate owned or controlled by the General Partner or any
Affiliate thereof as of the date thereof, (c) to acquire any residential
property for personal use by the General Partner or any of its Affiliates or any
family members of the same, (d) in connection with the sale or exchange of any
asset referred to in clauses (a) or (b) above, to acquire any improved or
unimproved property (including any partnership interests or shares in Real
Estate Investment Trusts) in an effort to mitigate any tax effect of such sale
or exchange, or (e) to acquire, hold, improve, develop, construct, maintain,
operate, manage, lease, mortgage, sell, exchange, dispose of and otherwise deal
in and exercise control over any assets now or hereafter owned or operated,
whether directly or indirectly, including through any existing intermediate
entities, and (ii) during the respective period that an investment partnership
is in the process of being dissolved and during any period following such
dissolution, then the general partner of such dissolving or dissolved investment
partnership shall confine any such activities to the respective investments of
the investment partnership in which it is or was a general partner and any
investments which it may acquire as a distribution in kind from the investment
partnership or through any tax-deferred exchange or similar transaction in an
effort to avoid the recognition of taxable income.

                  SECTION 4.4. Restrictions on Advisory Work. By their
respective signatures attached hereto Ross Dworman and Kenneth F. Bernstein
agree that during the period prior to the time at which the Remaining Capital
Commitments of the Limited Partners is equal to or less than Ten Million Dollars
($10,000,000), they shall not, without first consulting with the Advisory
Committee,

                                       21

720885.2


<PAGE>



cause any Advisory Entity (as hereinbelow defined), to provide any Advisory
Services (as hereinbelow defined), other than services performed on behalf of a
Limited Partner.

As used in this Section 4.5:

                  (a) "Advisory Entity" means (i) the General Partner, (ii) RD
Capital, Inc. (iii) Acadia Management Company LLC and (iv) any Affiliate of any
of the Persons listed in clauses (i) through (iii) above. The term control, as
used in the preceding sentence, shall have the same meaning as in the definition
of Affiliate as set forth in Section 1.1.

                  (b) "Advisory Services" means property advisory services or
investment advisory services pertaining to any real property assets (without
regard to whether such real property assets are located within the geographic
area in which Investments are permitted hereunder). Advisory Services does not
include (i) any property management services or real estate leasing, sales or
loan brokerage services, or (ii) any services rendered in connection with any
real property asset that is described in Section 4.3 clauses (a) through (e),
inclusive. The Partners acknowledge that Ross Dworman, a member of the General
Partner, may, on behalf of family trusts and their affiliates, be involved in
various investments, which shall not conflict with the investment objectives of
the Partnership.

                  SECTION 4.5. Investment in Sub-Tier Entities. It is understood
that the General Partner has the right to make investments in other entities
including a Subsidiary Entity of the Partnership (collectively, a "Sub-Tier
Entity"). It is the intention of the Partners that, without the consent of the
Required Partners, their respective rights and obligations provided for in this
Agreement not be vitiated or altered in any material respect by reasons of the
Partnership's investment in any Sub-Tier Entity, as opposed to its direct
investment in any real estate asset, and that neither the General Partner nor
any of its Affiliates shall be entitled to be paid or receive in the aggregate
from the Partnership and any Sub-Tier Entity any fees, expenses or distributions
above the amount that would be so payable or receivable by or distributable to
such General Partner or its Affiliates in accordance with the terms of this
Agreement, if such Investment were made directly by the Partnership, rather than
through a Sub-Tier Entity. Accordingly, the General Partner agrees that, without
the consent of the Required Partners, it will not cause or permit the
Partnership to invest in any Sub- Tier Entity unless all of the conditions set
forth below have been satisfied.

                                       22

                  1. Such Sub-Tier Entity shall be a pass-through entity, such
as a partnership, for federal income tax purposes.

                  2. Under the terms of the partnership agreement or other
governing instrument or agreement of such Sub-Tier Entity, each Limited Partner

such Sub-Tier Entity as is provided for in this Agreement with respect to the
books and records of the Partnership.

                  3. Each Limited Partner of the Partnership shall receive the
same reports and statements with respect to such Sub- Tier Entity as are

made applicable in respect of such Sub-Tier Entity.

                  5. Under the terms of the partnership agreement or other
governing instrument or agreement of such Sub-Tier Entity, such Sub-Tier Entity
shall not be entitled to take any of the actions described in either Section
3.3(a)(i) or 3.3(a)(v) without the consent or approval of the Partnership; and
in each case the General Partner, on behalf of the Partnership, shall not grant
such consent or approval in respect of any Sub-Tier Entity without first
obtaining the consent to such action of the Required Partners.

                  6. The fees and other amounts which this Agreement permits to
be paid to or received by the General Partner and/or its Affiliates and the
expenses which this Agreement permits the General Partner to pay to itself
and/or its Affiliates on behalf and at the cost of the Partnership (including
but not limited to, Reimbursable Expenses) shall not be increased by virtue of
the Partnership's investment in any Sub-Tier Entity above the amount that such
would increase if such Investment were made directly by the Partnership rather
than through a Sub-Tier Entity, whether by reason of the payment by any Sub-Tier
Entity or higher fees or a greater amount of expenses than are permitted
hereunder in respect of the Partnership, the payment of fees or expenses by both
any Sub-Tier Entity and the Partnership for the same services or items, or the
distribution by such Sub-Tier Entity of amounts to the General Partner or any
Affiliate thereof.

shall be made binding on such Sub-Tier Entity.

                  8. Nothing in the partnership agreement or other governing
instrument or agreement of such Sub-Tier Entity shall in any way restrict the
right of the Limited Partners to exercise their remedies under Section 10.2 of
this Agreement or to substitute another Person for the General Partner as
general partner of the Partnership.

                  9. The provisions required by this Section to be included in
the partnership agreement or other governing instrument or agreement of any
Sub-Tier Entity shall not be subject to amendment without the consent of the
Partnership, which consent shall not be granted without the consent of the
Required Partners.

                  10. The provisions of Section 3.3(b) shall apply to any
Sub-Tier Entity.

                  SECTION 4.6.  Additional Rights of Limited Partner with
Respect to the Investment.

                  (a)  Right of First Preference for Preferred Stock.

                  (i) If Mark Centers Trust has an offering of preferred stock
convertible into common shares of beneficial interest of Mark Centers Trust (the
"Offered Stock"), it has agreed, pursuant to the Contribution Agreement, to use
its commercially reasonable efforts to provide each Limited Partner and the
limited partners of the Sister Partnerships (collectively, with the Limited
Partners, the "Sister LPs" and individually, a "Sister LP") with a right of
first preference to purchase the first offering or offerings with respect to an
aggregate of $75 million (the "Offering") of such Offered Stock which occurs
subsequent to the Closing Date, on terms and conditions which will be identical
to the offer and sale of such Offered Stock to investors other than the Sister
LPs. Notwithstanding the foregoing, up to $10 million of the Offering may be
reserved for persons other than the Sister LPs. If the Offering is increased to
up to $90 million, the excess of the amount of the Offering over $75 million may
also be reserved for Persons other than the Sister LPs, and if the Offering is
increased to above $90 million, the right of first preference to purchase shares
of Offered Stock in favor of the Sister LPs shall equal the sum of (I) $65
million and (II) the lesser of (A) $10 million and (B) the excess of (i) the
amount of the Offering over (ii) $90 million.

                  (ii) The Partners hereby acknowledge that the terms of the
Offered Stock will be subject to the discretion of Mark Centers Trust.
Notwithstanding the foregoing, the General Partner, as authorized in the
Contribution Agreement, hereby grants to each Limited Partner and agrees that
each Limited Partner shall have the right, and agrees to use its best efforts to
cause Mark Centers Trust to offer to each Limited Partner the right to acquire
at least its pro rata share of the Offered Stock. The General Partner hereby
agrees that the Sister LPs shall have the right to acquire the Offered Stock in
accordance with the following procedures:

                  1. If any Limited Partner and any or all of the other Sister
                  LPs elect to acquire all or any portion of the Offered Stock,
                  then such Limited Partner may acquire up to its pro rata share
                  of the Offered Stock. Such pro rata share shall be determined
                  by multiplying the number of shares of Offered Stock times a
                  fraction, the numerator of which is the number of Shares
                  acquired by the Partnership and the denominator of which is
                  the aggregate number of Shares and common shares of beneficial
                  interest of Mark Centers Trust acquired by the Partnership and
                  the Sister Partnerships, and then applying each Limited
                  Partner's Interest Percentage to such amount.

                  2. If any Sister LP elects not to purchase all or any portion
                  of its pro rata share of the Offered Stock, the General
                  Partner will use its best efforts to cause Mark Centers Trust
                  to offer to each Limited Partner and Sister LPs which have
                  agreed to purchase Offered Stock the right to purchase some or
                  all of the remaining Offered Stock. The Limited Partners and
                  those Sister LPs desiring to purchase additional shares of
                  Offered Stock may purchase up to their pro rata share as
                  determined above (but excluding from the calculation the
                  Interest Percentage of any Limited Partner which has not
                  agreed to purchase Offered Stock) of the remaining Offered
                  Stock until such remaining Offered Stock is either purchased
                  or the Limited Partner or the other Sister LPs no longer
                  desire to purchase such Offered Stock.

                  3. A Limited Partner may condition its offer to acquire
                  Offered Stock on the purchase of a minimum number of shares or
                  dollar amount of Offered Stock, and may acquire less shares of
                  Offered Stock than its pro rata share.

                  (b) Registration Rights. Reference is made to the form of
Registration Rights and Lock-Up Agreement attached as Exhibit E to the
Contribution Agreement (the "Registration Rights Agreement"). To the extent the
final Registration Rights Agreement entered into on the Closing Date does not
provide that the rights of the Partnership thereunder are automatically
assignable to transferees of the Shares, the General Partner, on behalf of the
Partnership, hereby agrees to assign such rights to the Limited Partners upon
any distribution of the Shares from the Partnership and the General Partner will
cause the Partnership to execute and deliver any and all documents necessary to
effect such assignment. The General Partner hereby warrants that under the terms
of the Registration Rights Agreement such rights are so assignable.

                  (c) Tag-Along Rights. (i) If the General Partner or any
Affiliate of the General Partner (collectively with the General Partner, a "GP
Affiliate") desires to sell or otherwise dispose of (other than a pledge in
connection with a borrowing) any common shares of beneficial interest of Mark
Centers Trust, options to purchase common shares of beneficial interest of Mark
Centers Trust (not including the exercise of employee stock options granted to
such GP Affiliate who is an officer or trustee of MCT), operating partnership
units of Mark Centers Limited Partnership or other securities convertible into
or exchangeable for common shares of beneficial interest of Mark Centers Trust
(collectively, "MCT Securities") held by it to any other Person other than a GP
Affiliate (a "Third Party Sale"), the GP Affiliate shall, at least thirty (30)
Business Days prior to the proposed closing date of such Third Party Sale, give
written notice to the Limited Partners describing such Third Party Sale in
reasonable detail including the price offered and all material terms and
conditions of the Third Party Sale.

                  (ii) Each Limited Partner shall have the right and the option,
by written notice given to the selling GP Affiliate within fifteen (15) Business
Days prior to the closing of such Third Party Sale, to sell in such Third Party
Sale the same percentage of the total number of Shares held by the Limited
Partner (which for this purpose shall mean Shares held by the Limited Partner
and Shares held by the Partnership for the account of the Limited Partner) (or
direct the Partnership to sell such number of Shares) as the number of MCT
Securities to be sold by the selling GP Affiliate represents to all MCT
Securities held by such GP Affiliate.

                  (iii) In the event a Third Party Sale is proposed, the right
granted under this Section 4.6(c) shall be exercisable by the Partnership at the
written request of the Limited Partner.

                  (d) Pre-emptive Rights. In the event that any GP Affiliate
receives pre-emptive rights to acquire MCT Securities (the "Pre-emptive
Rights"), such GP Affiliate shall grant to the Limited Partners and/or use its
best efforts to cause Mark Centers Trust (or other grantor of Pre-emptive
Rights) to grant to each Limited Partner and the other Sister LPs Pre-emptive
Rights to acquire, at terms no less favorable than those offered to the GP
Affiliates, the same aggregate number of MCT Securities as are subject to the
Pre-emptive Rights offered to such GP Affiliates. Of such Pre-emptive Rights to
be granted to the Sister LPs, each of the Limited Partners shall be entitled to
acquire its pro rata share of such MCT Securities. Such pro rata share shall be
determined in the same manner as is set forth in Section 4.6(a)(ii).

                  (e) Pass-through of Right to Purchase. In the event that Mark
Centers Trust commences a rights offering for any securities or other similar
offering of rights or securities to its shareholders, the Limited Partner may
exercise the rights granted to shareholders of Mark Centers Trust, as if it were
a shareholder with respect to the Shares not otherwise previously distributed to
it pursuant to this Agreement; provided the cost of exercising such rights shall
be paid directly by the Limited Partner.

                  (f) Voting Proxy. Notwithstanding anything else contained in
this Agreement, the General Partner hereby constitutes and appoints each Limited
Partner its true and lawful attorney, agent and proxy to exercise all voting
rights of shareholders of Mark Centers Trust with respect to the number of
Shares owned by the Partnership which would otherwise be distributable to the
Limited Partner if the Partnership were liquidated.

                  (g) Any purchase of securities pursuant to Sections 4.6(a),
(d) and (e) hereof (i) which are required to be purchased in the name of the
Partnership, shall be purchased by the Partnership (upon a contribution of cash
by the Limited Partner therefor) and shall immediately be distributed by the
Partnership to the Limited Partner, (ii) shall not be deemed property of the
Partnership and (iii) shall not be subject to the provisions of this Agreement,
including without limitation, the provisions relating to the Preferred Return,
Carried Interest or distributions.

                  (h) The provisions of Section 4.6(c) through (f) shall
terminate at the earlier to occur of (i) the termination or dissolution of the
Partnership and (ii) thirty (30) months after the MCT Closing Date
(collectively, the "Expiration Date"). The provisions of Section 4.6(a) shall
survive the termination or dissolution of the Partnership only if an offering of
Offered Securities has not occurred prior to the Expiration Date and the General
Partner will do whatever is necessary to confirm the continuation of such rights
to the Limited Partners. The provisions of Section 4.6(b) shall survive the
termination or dissolution of the Partnership.

                                    ARTICLE V

                  CAPITAL COMMITMENTS AND CAPITAL CONTRIBUTIONS

                  SECTION 5.1.  Capital Commitments.

                  (a) Each Partner hereby agrees to make Capital Contributions
to the Partnership from time to time as hereinafter set forth; provided that
notwithstanding any other provision of this Article V, no Partner shall be
required to make any Capital Contribution to the Partnership to the extent that
such Capital Contribution exceeds such Partner's then Remaining Capital
Commitment.

                  (b) Upon the execution and delivery of a counterpart of this
Agreement, each such additional Limited Partner shall become a Limited Partner
of the Partnership and shall be shown as such on the books and records of the
Partnership. No additional Limited Partner shall be admitted to the Partnership,
and no existing Limited Partner shall be allowed to increase its Capital
Commitment, if the admission of such Limited Partner or the increase by such
Limited Partner of its Capital Commitment would, in the judgment of the General
Partner, cause a dissolution of the Partnership under the Delaware Act, cause
the Partnership to be deemed to be an "investment company" for purposes of the
Investment Company Act of 1940, or cause the Partnership to violate, any
applicable law or regulation, including any applicable Federal or state
securities laws, or result in the Partnership being treated as a publicly traded
partnership for federal income tax purposes.

                  SECTION 5.2.  Drawdown Procedures.

                  (a) Subject to Section 5.1, each Partner shall make Capital
Contributions to the Partnership in such amounts and at such times as the
General Partner shall specify in notices

                                       28

720885.2


<PAGE>



(individually a "Drawdown Notice") delivered from time to time to such Partner
as hereinafter provided. Each drawdown by the Partnership of Capital
Contributions pursuant to a Drawdown Notice is hereinafter referred to as a
"Drawdown". All Capital Contributions shall be paid to the Partnership in
immediately available funds in United States dollars by 2:00 p.m. (New York
time) on the date specified in the applicable Drawdown Notice. Drawdowns may
only be made for amounts that the General Partner determines are reasonably
anticipated to be necessary to make Investments or to pay Partnership Expenses.

                  (b)(1) Except as otherwise provided in Section 5.2(c), each
Drawdown Notice shall specify:

                             (i)    the aggregate Capital Contributions to be
         made by the Partners (the "Drawdown Amount"),

                            (ii) the manner in which, and the expected date on
         which, such Drawdown is to be applied,

                       (iii) if such Drawdown is to be applied to an existing
         Investment, a description of the application of such amount and if to
         make a new Investment, a description of the expected material terms of
         the proposed Investment,

                            (iv) the required Capital Contribution to be made by
         each Partner,

                       (v) the date (the "Drawdown Date") on which such Capital
         Contribution is due (which shall be at least ten (10) Business Days
         from and including the date of delivery of the Drawdown Notice),

                            (vi) the account to which such Capital Contribution
         should be paid, and

                       (vii) that the General Partner acknowledges the continued
         existence of the representations and warranties made by it in Section
         12.5(a) hereof and that there is then no uncured breach by the General
         Partner of any of such representations and warranties and that the
         acknowledgements and agreements of Ross Dworman and Kenneth F.
         Bernstein, as set forth in clauses (a), (b), and (c) of Section 12.6,
         continue in existence and that there is no uncured breach of any of
         such acknowledgements and agreements.

                  The General Partner may reduce the Drawdown Amount by notice
to the Partners at least one (1) Business Day prior to any

                                       29

720885.2


<PAGE>



Drawdown Date. All payments made by the Partners to the Partnership pursuant to
a Drawdown Notice shall be deemed Capital Contributions to the Partnership
effective as of the Drawdown Date. Any Capital Contributions made by the
Partners in connection with any Drawdown for the purpose of making an Investment
that are not applied to the making of such Investment (other than reserves for
future needs and earnest money deposits with respect to such Investment) within
fifteen (15) Business Days of such Drawdown shall be returned to such Partners
(together with any amounts earned with respect thereto during such period). For
purposes of determining each Partner's Capital Contributions for the purpose of
Sections 6.1(a)(ii), Unreturned Capital and Remaining Capital Commitment, the
amount of such returned Capital Contributions shall reduce the Capital
Contributions made by such Partners.

                  (2) In connection with any Drawdown, each Partner shall be
required to make a Capital Contribution equal to the product of (x) such
Partner's Capital Commitment Percentage (at the time the Drawdown Notice is
delivered) times (y) the Drawdown Amount specified in the applicable Drawdown
Notice.

                  (c)(1) If, in connection with the making of any Investment or
the payment of any Partnership Expense in respect of which a Drawdown Notice has
been delivered, the General Partner shall determine that it is necessary or
desirable to increase the required Capital Contributions to be made by the
Partners in connection therewith, the General Partner shall deliver an
additional Drawdown Notice to each Partner, amending the original Drawdown
Notice and specifying:

                  (A)  the amount of any increase in the Drawdown Amount,

                  (B) the amount of the increase in the required Capital
         Contribution to be made by such Partner,

                  (C) the Drawdown Date with respect to the amount of the
         increase in the required Capital Contribution if different from the
         Drawdown Date specified in the original Drawdown Notice, and

                  (D) the reason for such increase.

                  (2) If the amount of the increase in the required Capital
Contribution of any Partner is equal to or less than 25% of the required Capital
Contribution specified in the original Drawdown Notice, the Drawdown Date with
respect to such incremental amount shall be no earlier than the later of (i) the

                                       30

720885.2


<PAGE>



Drawdown Date specified in the original Drawdown Notice and (ii) five (5)
Business Days from and including the date of delivery of the additional Drawdown
Notice. If the amount of such increase is greater than 25% of the required
Capital Contribution specified in the original Drawdown Notice, the Drawdown
Date with respect to such incremental amount shall be no earlier than the later
of (x) the Drawdown Date specified in the original Drawdown Notice and (y) ten
(10) Business Days from and including the date of delivery of the additional
Drawdown Notice.

                  (d) If after the Full Investment Date the General Partner
shall determine that it is necessary or desirable to have the Partners make
additional contributions of capital to the Partnership to pay any Partnership
Expense or otherwise in connection with any existing Investment, and provided
that the Partners have been consulted regarding the delivery of a Drawdown
Notice, the General Partner shall be entitled to deliver appropriate Drawdown
Notices in accordance with Section 5.2(a) and the Partners shall be obligated to
comply therewith in accordance with the otherwise applicable provisions of
Section 5.2, including requiring that any Capital Contribution made by any
partner be made in proportion to such Partner's Capital Commitment Percentage to
the Capital Commitment Percentages of all the other Partners.

                  SECTION 5.3.  Default Loans.

                  (a) If any Partner (the "Defaulting Partner") shall fail to
advance the full amount of its share of any Capital Contribution on or before
the Drawdown Date therefor, distributions of Distributable Proceeds to the
Defaulting Partner shall be immediately suspended, the General Partner shall
immediately notify the other Partners of such default and the amount thereof and
each of the other Partners (a "Non-Defaulting Partner") shall have the right,
but not the obligation, to advance to the Partnership on behalf of such
Defaulting Partner, within fifteen (15) Business days after the Drawdown Date,
an amount of money equal to its proportionate share (based upon the ratio of the
Capital Commitment Percentages of those Non- Defaulting Partners to each other
or in such other proportion as they may agree) of the amount of the Capital
Contribution the Defaulting Partner was required to but did not make, which
advance shall be considered a loan (a "Default Loan") from the Non-Defaulting
Partner to the Defaulting Partner and shall bear interest on the outstanding
principal amount thereof at an annual rate equal to the lesser of (x) the Prime
Rate plus 3% (but in no event less than the rate provided in Section 6.2), and
(y) the maximum rate permitted by law, for the period commencing on the

                                       31

720885.2


<PAGE>



date of the advance by the Non-Defaulting Partner to, but not including, the
date of repayment thereof. Each Non-Defaulting Partner which has made the
maximum Default Loan permitted hereunder shall also have the right but not the
obligation to make an additional Default Loan within thirty (30) Business Days
after the Drawdown Date, corresponding to its proportionate share (based upon
the ratio of the Capital Commitment Percentages of those Non-Defaulting Partners
to each other or in such other proportion as they may agree) of any amount not
contributed by any other Non-Defaulting Partner. The amount of each Default Loan
(excluding interest) shall be reflected on the books of the Partnership as, and
shall be deemed for the purposes of this Agreement, a Capital Contribution by
the Defaulting Partner.

                  (b) Each Default Loan shall have a term of 180 days from the
date of its advance. At any time within such 180-day period the Defaulting
Partner shall have the right to satisfy and discharge the Default Loan by paying
to the Non-Defaulting Partners the amount of their respective Default Loan
(including interest). As long as any Default Loan remains unpaid, the Defaulting
Partner's share of any Distributable Proceeds shall be paid on behalf of the
Defaulting Partner to the Non-Defaulting Partners pro rata in accordance with
the respective amounts of their Default Loans and applied first to the payment
of interest on such Default Loans and then to the repayment of the principal
amount thereof.

                  (c) If any of the Non-Defaulting Partners makes a Default
Loan, the Defaulting Partner, if a Limited Partner, shall be deemed to have
pledged to such Non-Defaulting Partner, and granted to such Non-Defaulting
Partner a continuing security interest in, all of the Defaulting Partner's
Interest to secure the payment of the principal of, and interest on, such
Default Loan in accordance with the provisions hereof, and for such purpose this
Agreement shall be deemed a security agreement. Notwithstanding anything herein
to the contrary, the security interest granted to a Non-Defaulting Partner under
this Section 5.3(c) is hereby expressly made subordinate to the security
interest granted to the Partnership under Section 2.6. The Defaulting Partner,
if a Limited Partner, shall promptly execute, acknowledge and deliver such
financing statements, continuation statements or other documents and take such
other actions as the Non-Defaulting Partners shall reasonably request in order
to perfect or continue the perfection of such security interest; and, if the
Defaulting Partner shall fail to do so within five (5) days after demand
therefor, the General Partner is hereby appointed the attorney-in-fact of, and
is hereby authorized on behalf of, the Defaulting Partner, to execute,
acknowledge and

                                       32

720885.2


<PAGE>



deliver all such documents and to take all such other actions as may be required
to perfect such security interest. Such appointment and authorization are
coupled with an interest and shall be irrevocable.

                  (d) Any Limited Partner who is a Defaulting Partner pursuant
to the terms of this Agreement shall not have any of the rights to consultation,
or voting, consent or approval rights, if any, enumerated in this Agreement, nor
shall he be able to participate in any future property investments made by the
Partnership subject to the permission of the General Partner.

                  (e) The General Partner may, in its reasonable discretion,
waive a default by a Defaulting Partner, except that any such waiver shall not
reduce or impair the rights of any other Partner who makes a Default Loan.

                  SECTION 5.4. Non-Payment of Default Loans. If the Defaulting
Partner has not repaid in full a Default Loan and the interest due thereon
within 180 days after the advance of such Default Loan by a Non-Defaulting
Partner, each Non-Defaulting Partner shall have the right upon ten (10) Business
Days' notice to the General Partner and the Defaulting Partner to exchange the
unpaid portion of its Default Loan and the interest due thereon (the "Exchange
Amount") for a percentage of the Defaulting Partner's Interest (including such
Defaulting Partner's Capital Account and Interest Percentage, but excluding its
Capital Commitment Percentage) having a fair market value equal to 110% of the
Exchange Amount. The fair market value of the Defaulting Partner's Interest as
of the date of the conversion of the Exchange Amount shall be the lesser of: (i)
the then Unreturned Capital of the Defaulting Partner; or (ii) if the
Investments have been appraised, the amount which the accountants for the
Partnership estimate would be distributed to the Defaulting Partner if the
Investments were sold at the most recent appraised value and the Partnership
dissolved in accordance with Article IX (with the good faith estimation of such
accountants to be binding upon all Partners). In the event of such exchange, the
Exchange Amount shall be deemed to have been applied to pay the Default Loan in
full, and the Defaulting Partner shall execute and deliver to the Non-Defaulting
Partner all instruments necessary to effectuate such exchange and, if the
Defaulting Partner shall fail to do so within five (5) days after demand
therefor, the General Partner is hereby appointed the attorney-in-fact of, and
is hereby authorized on behalf of, the Defaulting Partner, to execute,
acknowledge and deliver all such instruments and to take all such other actions
as may be required to effectuate such exchange. Nothing herein shall be deemed
to require a Non- 

                                       33
720885.2

<PAGE>

Defaulting Partner to accept such an exchange of a percentage
of a Defaulting Partner's Interest instead of either pursuing its rights as a
secured creditor or seeking repayment of the Default Loan personally from the
Defaulting Partner or from any Distributable Proceeds thereafter payable on
behalf of the Defaulting Partner.

                  SECTION 5.5. Defaults not Supported by Default Loans. (a) To
the extent the amount of a Capital Contribution a Defaulting Partner was
required to but did not make exceeds the aggregate amount of Default Loans to
such Defaulting Partner with respect to such required Capital Contribution, such
excess shall not be treated as a Capital Contribution by the Defaulting Partner.
Further, such Defaulting Partner's Interest Percentage (and its right to
Distributable Proceeds under clause (iii) of Section 6.1(a)) shall be reduced in
proportion to the ratio, as determined by the General Partner, of (i) the sum of
the fair market value of the Defaulting Partner's Interest immediately prior to
the date of delivery of the Drawdown Notice with respect to which it failed to
make a Capital Contribution (to be determined in the manner provided in the
second sentence of Section 5.4) plus the amount of the Capital Contribution, if
any, made by such Defaulting Partner pursuant to such Drawdown Notice minus ten
percent (10%) of the amount of the Capital Contribution which such Defaulting
Partner failed to make pursuant to such Drawdown Notice to (ii) the sum of the
aggregate fair market value of all the Partners' Interests on such date (to be
determined in the manner provided in the second sentence of Section 5.4) plus
the total amount of Capital Contributions made pursuant to such Drawdown Notice.
The Interest Percentages (and the rights to Distributable Proceeds under clause
(iii) of Section 6.1(a)) of the other Partners shall be adjusted accordingly.
Any deemed adjustment in the aggregate Percentage Interests of the other
Partners pursuant to this Section 5.5 shall be allocated among such Partners in
accordance with their relative Percentage Interests obtained immediately prior
to the time of such deemed increase. The General Partner shall be authorized,
without any further action or consultation with any Partner, to amend this
Agreement to reflect the adjustments to the Interest Percentages of the Partners
required by this Section 5.5, including any changes in the tax allocations
contained herein that, in the sole discretion of the General Partner, are
necessary to reflect such adjustments in compliance with the Code, Regulations
and generally accepted accounting principles. The General Partner may also, in
lieu of such procedure or in addition to such procedure, pursue any remedies
available to the Partnership, in law or at equity, against the Defaulting
Partner,

                                       34

720885.2


<PAGE>



including the commencement of an action seeking specific
performance and/or damages.

                  (b) The General Partner may pursue any remedies available to
the Partnership, in law or at equity, against any Partner who fails to make a
Capital Contribution as required pursuant to this Agreement, including the
commencement of an action seeking specific performance and/or damages, and after
the closing of the transactions contemplated by the Contribution Agreement, if
the Limited Partner has failed to make all or a portion of its Capital
Contribution attributable to the Shares, the General Partner's rights hereunder
to pursue such remedies may be exercised by Mark Centers Trust directly.
Notwithstanding the foregoing, the Partners shall not be obligated to make
Capital Contributions attributable to the Shares as described herein if (i)
there is an amendment to the Contribution Agreement that could reasonably be
expected to be materially adverse to the Investment, or any Limited Partner or
the Partnership, or (ii) the General Partner (or an Affiliate of the General
Partner) waives a condition to closing under the Contribution Agreement which
could reasonably be expected to be materially adverse to the Investment, any
Limited Partner or the Partnership. For purposes hereof, any change to (i) the
purchase price per Share, (ii) the aggregate amount to be invested by all of the
Sister Partnerships in excess of $120 million, (iii) the aggregate number of and
percentage of the outstanding shares of beneficial interest of Mark Centers
Trust represented by the Shares to be purchased, as compared with such number
and percentage assuming a purchase by the Partnership and the Sister
Partnerships of 16 million Shares at $7.50 per share, (iv) the right of first
preference to purchase Offered Stock, shall be deemed to be materially adverse,
or (v) any increase over $25 million in the aggregate amount of Offered Stock
offered to, or reserved for, any person other than the Limited Partners and the
Sister LPs. Once a Limited Partner has made its Capital Contributions pursuant
to Section 5.1 in an amount equal to its Capital Commitments, it shall have no
further obligation to make any contributions to the capital of the Partnership.

                  SECTION 5.6. Temporary Investment of Funds. Subject to a
determination by the General Partner as to the amount of cash required in
connection with the conduct of the Partnership's business, the General Partner
shall invest all cash held by the Partnership in money market instruments which
instruments shall be (i) debt instruments issued or guaranteed by the United
States or its agencies or instrumentalities maturing within six months or less
from the date of acquisition, (ii) commercial paper rated P-1 or A-1 on the date
of acquisition and maturing within six

                                       35

720885.2


<PAGE>



months or less from the date of acquisition, (iii) overnight time deposits or
other interest-bearing deposits (whether or not insured) in national or state
banks (a) having capital and surplus of at least $1,000,000,000 and having a
long-term senior debt rating by Standard & Poor's Corporation of "A" or better
(or an equivalent rating issued by Moody's Investors Service, Inc.) or (b)

Distributable Proceeds promptly after the Partnership receives such proceeds.

                  (c) Notwithstanding anything in this Agreement to the
contrary, the Partnership shall make no distributions except to the extent
permitted under the Act.

                           (iii) If during the term of this Agreement any Shares
         are distributed to any Limited Partner, the following provisions shall
         apply:

                             (A) The distribution of such Shares shall not
                       reduce the Limited Partner's Unreturned Capital or
                       Interest Percentage.

                             (B) Any cash received by the Limited Partner in
                       respect of such Shares, whether dividends or net proceeds
                       of sale, shall be deemed to have been received by the
                       Partnership and shall be deemed to have been distributed
                       to the Partner pursuant to Section 6.1(a) for all
                       purposes of this Agreement; provided, however, that there

                       distribution; and provided further, however, that if the
                       offset above provided for exceeds the amount of the
                       deemed distribution being made to the Limited Partner,
                       the Limited Partner shall pay an amount equal to such
                       excess to the General Partner, but only to the extent of
                       the amount of the deemed distribution then made to the
                       General Partner.

                             (C) If on a date which is the earlier of 60 months
                       after the MCT Closing Date and a date selected by any
                       Limited Partner (which shall be 36 months or more after
                       the MCT Closing Date), a Limited Partner shall be holding
                       Shares previously distributed to it by the Partnership,
                       the Fair Market Value of such Shares, net of brokerage or
                       underwriting commissions that would be incurred if such
                       Shares then held by such Limited Partner were then sold,
                       shall be deemed to have been received by the Partnership
                       and the provisions of Section 6.1(e)(iii)(B) shall apply
                       to such amount. Any amount due to the General Partner as
                       a result of its deemed distribution pursuant to this
                       subsection 6.1(e)(iii)(C) shall be paid by the Limited
                       Partner to the General Partner in cash or in Shares, as
                       elected by the Limited Partner. Each Limited Partner will
                       consider, but is not obligated with respect to, a request
                       from the General Partner for the Carried Interest to be
                       paid to the General Partner in Shares.

                             (D) In order that the provisions of Section
                       6.1(e)(iii)(B) can be effectuated, each Limited Partner
                       shall give the General Partner notice each time such
                       Limited Partner sells any Shares distributed to it by the
                       Partnership, and in such notice shall set forth the
                       amount of the net proceeds received by the Limited
                       Partner upon said sale. The obligations of the Limited
                       Partners under Section 6.1(e)(iii)(D) shall terminate on
                       the earliest of 60 months after the MCT Closing Date, the
                       date on which Shares held by such Limited Partner are
                       valued pursuant to Section 6.1(e)(iii)(C) and the date on
                       which all Shares held by such Limited Partner and held by
                       the Partnership in which such Limited Partner has an
                       interest have been sold.

                            (iv) The Carried Interest will remain in effect with
         respect to distributed Shares until sixty months after the MCT Closing
         Date (or the date selected by the Limited Partner in accordance with
         clause (c), above). At the time each Limited Partner determines to sell
         Shares, each Limited Partner will consider, but is not obligated with
         respect to, a request from the General Partner for the Carried Interest
         to be paid to the General Partner in Shares.

                             (v) Whenever any distribution or deemed
         distribution is to be made to the General Partner pursuant to Section
         6.1(a)(iii) and/or Section 6.1(e)(iii) by reason of the sale of any
         Shares by the Partnership or a Limited Partner or pursuant to Section
         6.1(e)(iii)(C), such distribution or deemed distribution shall be
         reduced to reflect (A) the aggregate "value" on the date of the
         distribution or deemed distribution of the Share options in Mark
         Centers Trust held by and/or previously exercised by Ross Dworman and
         Ken Bernstein, (B) any extraordinary compensation that has been paid by
         Mark Centers Trust to Ross Dworman and/or Ken Bernstein (i.e., bonus
         compensation in excess of amounts customarily paid to executive
         officers of public real estate investment trusts), as reasonably
         determined by the Limited Partners and (C) the net present value,
         calculated using a discount rate equal to Treasury Securities of
         similar maturity, of amounts payable by Mark Centers Trust to Ross
         Dworman and/or Kenneth Bernstein as a result of a change in control (as
         defined in any agreement between Mark Centers Trust and either Ross
         Dworman or Kenneth Bernstein) of Mark Centers Trust (the "Excess
         Compensation")). The distribution or deemed distribution to the General
         Partner will be reduced by an amount equal to (a) the "value" of all
         vested Share options held by and/or previously exercised by Ross
         Dworman and Ken Bernstein and the Excess Compensation multiplied by (b)
         a fraction, the numerator of which is the number of Shares sold by the
         Partnership or the Limited Partner or the number of Shares being valued
         and the denominator of which is all of the issued and outstanding
         shares of Mark Centers Trust and units of Mark Centers Limited
         Partnership, on a fully diluted basis. For purposes of this
         calculation, the "value" of the share options shall be determined using
         the Black-Scholes method for unexercised options and shall be the
         excess of the closing market price of shares acquired pursuant to
         options over the purchase price of such shares, for exercised options.

                  SECTION 6.2. Preferred Return. No later than nor less
frequently than the thirtieth (30th) day following the close of each fiscal
quarter, the General Partner shall determine, based on a statement of operations
and cash flow for the Partnership, which need not be audited, and distribute to
the Partners to the extent of Distributable Proceeds, pro rata in accordance
with their respective amounts of Unreturned Capital, an amount, in the
aggregate, equal to eight percent (8%) per annum of the average monthly balance
of such Partners' aggregate Unreturned Capital (the "Preferred Return")since the
last distribution of

                                       40

720885.2


<PAGE>



Distributable Proceeds. To the extent the Partnership is unable to make a
Preferred Return payment pursuant to this Section 6.2 in any quarter, the unpaid
amount of the Preferred Return will be compounded semiannually at a rate of 8%
per annum and paid in future quarters. No amounts shall be distributed to
Partners pursuant to Section 6.1 (other than Section 6.1(a)(i)) if any Preferred
Return amount required to be paid under this Section 6.2 is accrued but unpaid.
Amounts paid pursuant to this Section 6.2 are intended to constitute payments of
a preferred return for capital within the meaning of Treasury Regulations ss.
1.514(c)- 2(d)(2) and not guaranteed payments within the meaning of Section
707(c) of the Code.

                  SECTION 6.3.  Capital Accounts.  (a)  There shall be
established for each Partner on the books and records of the
Partnership an account (a "Capital Account"), which shall
initially be zero and which shall be adjusted as follows:

                             (i) The amount of cash contributed or deemed
         contributed to the Partnership by each Partner, including amounts
         contributed or deemed contributed pursuant to Article V (including
         Section 5.3(a)) shall be credited to the Capital Account of such
         Partner.

                            (ii) The amount of cash (or the fair market value of
         other property as determined by the General Partner pursuant to this
         Article VI, net of any liabilities assumed or taken subject to by the
         Partners) distributed or deemed distributed by the Partnership to each
         Partner shall be debited against the Capital Account of such Partner.

   
                             (iii) The Net Income and Net Loss of the
         Partnership (and the items entering into the determination thereof)
         allocated to each Partner pursuant to this Article VI shall be credited
         to and debited against, respectively, the Capital Account of such
         Partner.
    

                       (b)  If all or any portion of an Interest is
transferred in accordance with this Agreement, the transferee shall succeed to
the Capital Account of the transferor to the extent it relates to the
transferred Interest or portion thereof.

                       (c)  The provisions of this Agreement relating to
the maintenance of Capital Accounts are intended to comply with applicable
Regulations under Code Section 704 and to provide for allocations which have
"substantial economic effect" within the meaning of those Regulations or, in the
case of allocations attributable to nonrecourse indebtedness, which are deemed

                                       41

720885.2

pursuant to those Regulations to be in accordance with the Partners' Interests.
Subject to Section 6.5, the provisions of this Agreement shall be interpreted
and applied in a manner consistent with this intention. Moreover, in determining
the amount of any liability for purposes hereof, Code Section 752 and the
Regulations thereunder shall be applied insofar as relevant. In the event the
General Partner shall determine that it is prudent to modify the manner in which
the Capital Accounts, or any debits or credits thereto, are computed in order to
comply with such Regulations, the General Partner may make such modification,
subject to Section 6.5 and provided that no such modification that has a
material adverse effect upon any Partner shall be made without that Partner's
consent.

                  SECTION 6.4.  Allocations of Net Income and Net Loss.

                  (a) Net Income. Except as otherwise provided in this Article
VI, Net Income for each Fiscal Year shall be allocated in the following order:

                             (i) first, if any Net Loss has been previously
         allocated to the Partners, reversing the prior allocations of Net Loss
         on a most recent in time basis until the cumulative amount allocated
         pursuant to this Section 6.4(a)(i) equals the cumulative amount of Net
         Loss previously so allocated; and

                            (ii) second, to the Partners in an amount equal to
         the distributions made to each Partner (or which would be made to each
         Partner, if the Partnership distributed cash in an amount equal to such
         Net Income) pursuant to Section 6.1(a)(i) and (iii).

                  (b) Net Loss. Except as otherwise provided in this Article VI,
Net Loss for each Fiscal Year shall be allocated first, if any Net Income has
previously been allocated to the General Partner with respect to its Carried
Interest, to the General Partner in an amount equal to such Net Income and then
to the General Partner and the Limited Partners in proportion to their Interest
Percentages.

                  (c) Miscellaneous. Any Net Income or Net Loss allocated to the
Limited Partners shall be allocated among the Limited Partners pro rata in
accordance with their Interest Percentages.

                  SECTION 6.5.  Other Allocations.

                  (a) UBTI. Notwithstanding anything to the contrary in this
Agreement:

                             (i) without violating the requirements of Section
         6.5(a)(ii), all allocations under this article VI may be adjusted
         insofar as may be required in the reasonable judgement of the General
         Partner in order to avoid the recognition of UBTI by the Limited
         Partners and to provide equitable allocations among the Limited
         Partners, provided, however, that the Partners shall be consulted
         regarding any such adjustment that has a material adverse effect upon
         the present value of cash distributions from the Partnership to any
         Partner (exclusive of tax allocations); and

                            (ii) although the parties confirm their good faith
         belief that the terms of this Agreement meet the requirements of Code
         Section 514(c)(9)(E), so that all allocations hereunder have
         "substantial economic effect" within the meaning of Code Section
         704(b)(2) (or in the case of an allocation that cannot have economic
         effect, are in accordance with the Partners' interests in the
         Partnership within the meaning of the applicable regulations under
         Section 704(c) of the Code) and so that as to each Partner, all
         allocations under this Agreement shall be adjusted insofar as may be
         required to enable the Partnership to meet the following requirements:

                             (A) each Limited Partner's percentage share of the
                  Partnership's "overall partnership income" (within the meaning
                  of Section 514(c)(9)(E)(i)(I) of the Code) shall not, for any
                  taxable year of the Partnership, be greater than such
                  Partner's Fractions Rule Percentage; and

                             (B) each Limited Partner's percentage share of the
                  Partnership's "overall partnership loss" (within the meaning
                  of Section 514(c)(9)(E)(i)(I) of the Code) shall not, for any
                  taxable year of the Partnership, be less than such Partner's
                  Fractions Rule Percentage, subject in either case to the
                  special rules of Section 514(c)(9)(E)(ii) of the Code.

                  (b) Regulatory Allocations. The following special allocations
shall be made in the following order:

                             (i) Notwithstanding any other provision of Article
         VI except Section 6.5(a)(ii), if there is a net decrease in
         "partnership minimum gain" or "partner nonrecourse debt minimum gain"
         (as defined in applicable Regulations under Code Section (704) for any
         Fiscal Year, then items of Partnership income and gain for such year
         (and, if necessary, subsequent years) shall be specially allocated
         among the Partners in accordance with requirements of such Regulations.
         This Section 6.5(b)(i) is intended to comply with the "minimum gain
         chargeback" and "partner nonrecourse debt minimum gain chargeback"
         requirements of such Regulations and shall be interpreted consistently
         therewith.

                            (ii) If any Partner unexpectedly receives any
         adjustments, allocations or distributions described in Regulations
         Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership
         income and gain shall be specially allocated to such Partner in
         accordance with the requirements of Regulation Section
         1.704-1(b)(2)(ii)(d). This Section 6.5(b)(i) is intended to comply with
         the "qualified income offset" provision of such Regulations and shall
         be interpreted consistently therewith.

                           (iii) If and to the extent required by applicable
         Regulations under Section 704 and computed after giving effect to such
         allocation to the Limited Partner of the Code, any "nonrecourse
         deductions" or "partner nonrecourse deductions" (within the meaning of
         such Regulations) shall be specially allocated in accordance with the
         requirements of such Regulations.

                            (iv) If for any Fiscal Year the Partnership has a
         Net Loss and the allocation of such Net Loss would otherwise give rise
         to a negative Capital Account balance for any Limited Partner in excess
         of such Limited Partner's share of "partnership minimum gain" (as
         defined in applicable regulations under Code Section 704), then that
         portion of such excess, to the extent otherwise allocable to any such
         Limited Partner, shall be allocated entirely to the General Partner.

                  (c)  Other Allocation Rules.

                             (i) To the extent required by Code Section 704 and
         the Regulations thereunder, income, gain, loss, deduction and credit
         with respect to any property shall, solely for tax purposes (and not
         for purposes of maintaining

                                       44

         the Capital Accounts hereunder), be allocated among the Partners so as
         to take account of any variation between the adjusted basis of such
         property for federal income tax purposes and its 704(c) Value. Any
         elections or other decisions relating to such allocation shall be made
         by the General Partner with the consent of the Required Partner.

                  "704(c) Value" means, with respect to any Partnership asset,
the adjusted basis for federal income tax purposes of such asset, adjusted as of
the following times to equal its gross fair market value (as determined by the
General Partner in its discretion): (a) the acquisition of an additional
Interest by any new or existing Partner in exchange for more than a de minimis
(as that term is used in Regulation Section 1.704-1(b)(2)(iv)(f)) Capital
Contribution; (b) the distribution by the Partnership to a Partner of more than
a de minimis amount of Partnership property or money if the General Partner
determines in its discretion that such adjustment is necessary or appropriate to
reflect the economic interests of the Partners in the Partnership; and (c) the
liquidation of the Partnership for federal income tax purposes within the
meaning of Regulation Section 1.704(b)(2)(ii).

                            (ii) Distributions during the course of any Fiscal
         Year shall be on account of the Net Income for that Fiscal Year to the
         extent of such Net Income.

                  SECTION 6.6. Tax Allocations. All items of income, gain, loss,
deduction or credit of the Partnership shall be allocated among the Partners for
federal income tax purposes in a manner consistent with the allocation of the
corresponding items to the Partners under the other provisions of this Article
VI.

                  SECTION 6.7. Distributions in Kind. The General Partner may
distribute any property constituting all or any portion of an Investment in
kind. Any property so distributed shall be deemed for purposes of determining
Net Income or Net Loss under this Article VI to have been sold by the
Partnership for an amount equal to its Fair Market Value in the case of Shares,
and its fair market value, in the case of other property. Except as provided in
Section 6.1(e), in any distribution of property in kind, the General Partner
shall not, without the consent of all the Limited Partners, discriminate among
Partners and shall endeavor to (i) distribute to each applicable Partner a
proportional interest in any particular property in accordance with this Article
VI and (ii) if cash and property in kind are to be distributed simultaneously in
respect of any Investment,

                                       45

720885.2


<PAGE>



distribute cash and property in kind in the same proportion to
each applicable Partner.

                  Notwithstanding the foregoing, if any Limited Partner notifies
the General Partner that such Limited Partner is prohibited by applicable law or
regulation from holding directly the property to be distributed in kind, the
General Partner shall, in lieu of making such distribution in kind to such
Limited Partner and to the extent permitted by applicable law, use commercially
reasonable efforts to sell such property on such Limited Partner's behalf, on
terms acceptable to such Limited Partner and, upon such sale, the General
Partner shall promptly distribute to such Limited Partner the net proceeds of
such sale.

                  SECTION 6.8. Setoff and Withholding of Certain Amounts.
Notwithstanding anything else contained in this Agreement, the General Partner
may in its discretion set off against, or withhold from, any distribution to any
Partner pursuant to this Agreement, the following amounts:

                  (a) any amounts due from such Partner to the Partnership or
the General Partner pursuant to this Agreement to the extent not otherwise paid,

                  (b) any amount owed by a Defaulting Partner on a Default Loan
pursuant to Section 5.3, and

                  (c) any amounts required to pay or reimburse (x) the
Partnership for the payment of any withholding or other taxes properly
attributable to such Partner or (y) the General Partner for any advances made by
the General Partner for such purpose.

                  Any amounts so set off or withheld pursuant to this Section
6.8 shall be applied by the General Partner to discharge the obligation in
respect of which such amounts were withheld. All amounts set off or withheld
either pursuant to this Section 6.8 or pursuant to the Code or any provision of
any state or local tax law attributable to any Partner shall be treated as
amounts distributed to such Partner for all purposes under this Agreement.

                  SECTION 6.9. Withdrawal and Return of Capital. Except as
specifically provided in this Agreement, a Partner shall not have any right to
demand the return of any Capital Contribution or to withdraw any portion of
Partnership capital. If the Distributable Proceeds remaining upon dissolution of
the Partnership after the payment or discharge of Partnership Expenses are
insufficient to return any Partner's Unreturned

                                       46

720885.2


<PAGE>



Capital, the Partner shall have no recourse against any of the Partners or
against the Partnership.

                  SECTION 6.10. Deemed Partnerships. Notwithstanding anything to
the contrary set forth in this Article VI or elsewhere in this Agreement, for
the purposes of calculating amounts to be distributed or to be deemed to have
been distributed to the Partners pursuant to this Article VI or Article IX, it
shall be deemed that the Partnership constitutes four separate partnerships,
each of which is between the General Partner and one of the Limited Partners
(each a "Deemed Partnership"). The Interest Percentage of the General Partner in
a Deemed Partnership shall be the Interest Percentage of the General Partner in
the Partnership multiplied by the Interest Percentage of the Limited Partner of
such Deemed Partnership in the Partnership. The Interest Percentage of the
Limited Partner in a Deemed Partnership shall be 100% less the Interest
Percentage of the General Partner therein. There shall be deemed owned by each
Deemed Partnership on the MCT Closing Date a number of Shares equal to the
number of Shares acquired by the Partnership on the MCT Closing Date multiplied
by a fraction, the numerator of which is the Interest Percentage of the Limited
Partner of said Deemed Partnership in the Partnership plus the Interest
Percentage of the General Partner in the Deemed Partnership and the denominator
of which is 100.

                           REPORTS TO LIMITED PARTNERS

                  SECTION 7.1.  Reports.

                  (a) The books of account and records of the Partnership shall
be audited as of the end of each Fiscal Year by the Partnership's independent
public accountants. All reports provided to the Limited Partners pursuant to
this Section 7.1 shall be prepared on an accrual basis. The Partnership's
independent public accountants shall be a nationally recognized independent
certified public accounting firm selected by the General Partner. Until such
time as the Limited Partners become shareholders of Mark Centers Trust, the
Partnership shall deliver to the Limited Partners a copy of any reports and
other correspondence sent by Mark Centers Trust to the Partnership, as a
shareholder of Mark Centers Trust promptly after receipt thereof.

                  (b) Within 60 days after the end of each fiscal quarter, the
General Partner shall prepare and mail to each Person who was a Partner during
such quarter an unaudited report setting forth as of the end of such fiscal
quarter:

                             (i)    unless such quarter is the last fiscal
         quarter, a balance sheet of the Partnership;

                            (ii) unless such quarter is the last fiscal quarter,
         an income and expense statement of the Partnership reflecting the cash
         flow of the Partnership for such fiscal quarter (including an estimate
         of the amount of UBTI that is expected to be incurred for such quarter
         and the related Fiscal Year); and

                             (iii) a status report of the Partnership's
         Investments (which report shall include occupancy percentages, leasing
         activity, a comparison of actual results to the budget for each
         Investment other than the Shares and an aging report for accounts
         receivable) and activities during such fiscal quarter, including
         summary descriptions of Investments made and disposed of by the
         Partnership, expenditures for renovation and construction, and amounts
         withheld for expenses or reserves upon Disposition (or the tax-deferred
         exchange) of an Investment during such fiscal quarter.

                  (c) Within 105 days after the end of each Fiscal Year, the
General Partner shall prepare (or cause to be prepared) and mail to each
Partner, an audited report setting forth as of the end of such Fiscal Year:

                             (i) a balance sheet of the Partnership,

                            (ii) an income and expense statement of the
         Partnership reflecting the cash flow of the Partnership for such Fiscal
         Year, and

                             (iii) a statement of each Partner's Capital
         Account.

                  (d) Each Limited Partner other than an Affiliate of the
General Partner agrees that it will not, and it will cause its employees,
representatives and advisors not to, disclose the information in any reports
issued pursuant to this Section 7.1 to any Person without the prior written
consent of the General Partner; provided that any Limited Partner may make such
disclosures as it reasonably believes may be required by law,

regulation or rule of any governmental authority or in
conjunction with any litigation proceeding.

                  (e) After the end of each Fiscal Year, the General Partner
shall cause the Partnership's independent certified public accountants to
prepare and transmit, as promptly as possible, and in any event within 90 days
of the close of the Fiscal Year, a federal income tax form K-1 for each Partner,
a copy of the Partnership's return filed for federal income tax purposes and a
report setting forth in sufficient detail such transactions effected by the
Partnership during such Fiscal Year as shall enable each Partner to prepare its
federal income tax return, if any. The General Partner shall mail such materials
to (i) each Partner and (ii) each former Partner (or its successors, assigns,
heirs or personal representatives) who may require such information in preparing
its federal income tax return.

                         EXCULPATION AND INDEMNIFICATION

                  SECTION 8.1.  Exculpation and Indemnification.

                  (a) Notwithstanding anything to the contrary in this
Agreement, the General Partner, its members and Affiliates and its and their
directors, officers, shareholders, partners, trustees and employees
(individually and respectively, a "Released Party") shall not be liable to the
Partnership or to the Limited Partners for any losses, claims, damages or
liabilities arising from any act or omission performed or omitted by such
Released Party arising out of or in connection with this Agreement or the
Partnership's business or affairs, except for (i) any such loss, claim, damage
or liability attributable to the negligence or willful misconduct of such
Released Party or a material breach of this Agreement which such Released Party
fails to cure, or fails to cause the General Partner to cure, within ten (10)
Business Days following receipt by the General Partner of notice of such breach
from the Required Partners (a "Breach"), provided that if such breach is capable
of being cured but cannot be cured with diligent efforts within such period of
10 Business Days and if such Released Party or the General Partner, as the case
may be, has commenced to cure such breach within such period of 10 Business
Days, no Breach of this Agreement shall be deemed to have occurred unless either
(a) such Released Party or the General Partner, as the case may be, ceases to
proceed diligently to cure such breach or (b) such breach is not cured within

                                       49

fifteen (15) days after the receipt by the General Partner of such notice of the
breach, or (ii) any such loss, claim, damage or liability attributable to or
arising out of or as a result of any Released Party's position as an officer,
director, trustee or controlling stockholder (except in the case of any such
loss, claim, damage or liability attributable to such person's position as a
controlling stockholder arising solely by reason of the initial funding of the
Partnership Investment pursuant to the Contribution Agreement) of Mark Centers
Trust or with respect to actions taken or omitted to be taken by them in such
capacity. The General Partner shall, to the fullest extent permitted by
applicable law, indemnify, defend and hold harmless the Partnership and the
Limited Partners against any losses, claims, damages or liabilities to which the
Partnership or such Limited Partners may become subject in connection with (i)
any Breach or (ii) actions or omissions of any Released Party after the Closing
Date relating to their positions as executive officers, trustees, directors or
controlling stockholders (except in the case of any such loss, claim, damage or
liability attributable to such person's position as a controlling stockholder
arising solely by reason of the initial funding of the Partnership Investment
pursuant to the Contribution Agreement) of Mark Centers Trust or actions taken
or omitted to be taken by them in such capacity.

                  (b) The Partnership shall, to the fullest extent permitted by
applicable law, indemnify, defend and hold harmless each Released Party against
any losses, claims, damages or liabilities to which such Released Party may
become subject in connection with any matter arising out of or in connection
with this Agreement or the Partnership's business or affairs, except for any
such loss, claim, damage or liability attributable to the gross negligence,
willful misconduct or Breach of such Released Party or as a result of any
Released Party's position as an officer, trustee, director or controlling
stockholder of Mark Centers Trust or with respect to actions taken by or omitted
to be taken by any Released Party in such capacity. If any Released Party
becomes involved in any capacity in any action, proceeding or investigation in
connection with any matter arising out of or in connection with this Agreement
or the Partnership's business or affairs, the Partnership shall reimburse such
Released Party for its legal and other expenses (including the cost of any
investigation and preparation) as they are incurred in connection therewith,
provided that such Released Party shall promptly repay to the Partnership the
amount of any such reimbursed expenses paid to it if it shall ultimately be
determined that such Released Party was not entitled to be indemnified by the
Partnership in connection with such action, proceeding or investigation. Any
such obligation of the Partnership shall be

                                       50

720885.2

limited to the assets of the Partnership and there shall be no personal
liability of any of the Limited Partners for any such obligation of the
Partnership.

                  (c) Each Partner covenants for itself and its successors,
assigns, heirs and personal representatives that such Person will, at any time
prior to or after dissolution of the Partnership, on demand, whether before or
after such Person's withdrawal from the Partnership, pay to the Partnership or
the General Partner any amount which the Partnership or the General Partner, as
the case may be, pays in respect of taxes (including withholding taxes) imposed
upon income of or distributions to such Partner.


                                   ARTICLE IX

                   DURATION AND DISSOLUTION OF THE PARTNERSHIP

                  SECTION 9.1. Duration. The term of the Partnership shall
commence on the Effective Date and, subject to Section 9.2 and Section
3.3(a)(iii), the term of the Partnership shall continue until the earlier of (i)
December 31, 2005, unless extended in accordance with Section 3.3(a)(iii) for no
more than three years thereafter, until December 31, 2008 and (ii) the date by
which no further distributions or deemed distributions will be made to the
Partners pursuant to Sections 6.1(a) or 6.1(e).

                  SECTION 9.2.  Dissolution.  Subject to the Act, the
Partnership shall be dissolved and its affairs shall be wound up
upon the earliest to occur of:

                  (a)  the expiration of the term of the Partnership
provided in Section 9.1;

                  (b)  the written consent of the Partners to dissolve
the Partnership;

                  (c) a decision made by the General Partner to dissolve the
Partnership because it has reasonably determined that changes in any applicable
law or regulation would have a material adverse effect on the continuation of
the Partnership and has delivered to the Required Partners an opinion of counsel
reasonably acceptable (as to the opinion itself and the counsel rendering such
opinion) to the Required Partners to that effect; and

                  (d) the withdrawal, removal or other cessation of the General
Partner as a general partner of the Partnership (within

                                       51

the meaning of the Act) or the termination of the active
engagement of either Ross Dworman or Kenneth F. Bernstein from
the Partnership.

                  SECTION 9.3. Winding Up of Partnership. Upon dissolution, the
Partnership's business shall be wound up in an orderly manner. The General
Partner shall be the liquidator to wind up the affairs of the Partnership
pursuant to this Agreement. If no general partner remains, the Limited Partners
may approve one or more liquidators to act as the liquidator in carrying out
such liquidation. Subject to the Act (and with respect to any distribution of
assets, Section 6.7), the liquidator shall dispose of or distribute all
Partnership assets to the Partners within one year following dissolution, except
that such one-year period may be extended with the approval of the Limited
Partners. During such winding up period the liquidator shall not pursue the
making of any Investments or require any further Capital Contributions from the
Partners unless, and then only to the extent, required to pay normal and
reasonable Partnership Expenses, and in all events, limited to the amount of
each partner's respective remaining Capital Commitment.

                  SECTION 9.4.  Distribution Upon Dissolution of the
Partnership.

                  (a) Upon dissolution of the Partnership, the liquidator shall
determine which assets of the Partnership shall be disposed of and, subject to
Section 6.7, which assets of the Partnership shall be retained for distribution
in kind to the partners. In performing its duties, the liquidator is authorized
to sell, distribute, exchange or otherwise dispose of the assets of the
Partnership in any manner that the liquidator shall determine to be in the best
interest of the Partners. Subject to the Act, after all liabilities contingent
or otherwise of the Partnership (including any liabilities to Partners and any
obligations to Partners under Section 6.2) have been satisfied or duly provided
for (as determined by the liquidator in its discretion), the remaining assets of
the Partnership shall be distributed to the partners in proportion to their
positive Capital Accounts (after giving effect to adjustments attributable to
all Partnership transactions prior to any such distribution).

                  (b) Subject to the Act, if at the time of dissolution, any new
construction, repair or rehabilitation of Partnership assets has not been
completed, then completion thereof shall be a proper act in winding up the
Partnership and the liquidator shall have full power and authority to do all
acts appropriate to

                                       52


720885.2


<PAGE>



complete any such construction, repair or rehabilitation in process, including
arranging for all appropriate financing. The full rights, powers and authority
of the liquidator shall continue so long as appropriate and necessary to
complete the process of winding up the business and affairs of the Partnership.

                  (c) In the discretion of the liquidator a portion of the
distributions that would otherwise be made to the Partners pursuant to this
Section 9.4 may be:

                             (i) distributed to a trust established for the
         benefit of the Partners for the purposes of liquidating Partnership
         assets, collecting amounts owed to the Partnership, and paying any
         liabilities or obligations of the Partnership or of the General Partner
         arising to of or in connection with the Partnership. (Subject to
         Section 6.7, the assets of any such trust shall be distributed to the
         Partners from time to time, in the discretion of the liquidator, in the
         same proportions as the amount distributed to such trust by the
         Partnership would otherwise have been distributed to the Partners
         pursuant to this Agreement); or

                            (ii) withheld to provide a reserve for Partnership
         liabilities (contingent or otherwise), provided that such withheld
         amounts shall be distributed to the Partners as soon as the liquidator
         determines, in its discretion, that such amounts are no longer
         necessary to be retained.

                  (d) Except as otherwise provided in this Agreement, (i) each
Partner shall look solely to the assets of the Partnership for the return of its
Capital Contributions and shall have no right or power to demand or receive
property other than cash from the Partnership and (ii) no Limited Partner shall
have priority over any other Limited Partner as to the return of its Capital
Contributions. Subject only to any applicable provisions of the Act, in
conjunction with the dissolution of the Partnership, no Partner shall have any
obligation to contribute to or reimburse the Partnership for any deficit in such
Partner's Capital Account.

                  SECTION 10.1.  Transferability of General Partner's
Interest.

                  (a) Except as otherwise provided herein, the General Partner
may not Transfer all or any portion of its Interest to any Person without the
prior approval of the Required Partners.

                  (b) In connection with any Transfer permitted hereunder, the
General Partner may admit a transferee as a general partner of the Partnership
without further action by any partner or any other Person, and such transferee
shall be deemed admitted to the Partnership as a general partner of the
Partnership immediately prior to the Transfer and shall continue the business of
the Partnership without dissolution.

                  (c) Notwithstanding, the foregoing, the General Partner agrees
that no Transfer contemplated by this Section 10.1 shall be effected if such
Transfer would jeopardize the status of the Partnership as a partnership for
federal income tax purposes.

                  (d) In connection with any Transfer permitted hereunder, all
expenses, including attorneys' fees and expenses, incurred by the Partnership in
connection with such Transfer shall be fully borne by the General Partner or the
General Partner's transferee. In addition, the General Partner or the General
Partner's transferee shall indemnify the Partnership in a manner reasonably
satisfactory to the Limited Partners against any losses, claims, damages,
liabilities or expenses to which the Partnership may become subject arising out
of or based upon any false representation or warranty made by, or breach or
failure to comply with any covenant or agreement of, the General Partner or the
General Partner's transferee in connection with such Transfer.

                  SECTION 10.2.  Removal of the General Partner.

                  (a) In the event of fraud, gross negligence, willful
misconduct, or an Event of Default by the General Partner, the General Partner
may be removed by written notice (a "Removal Notice") from Limited Partners
(other than a Defaulting Partner and any Limited Partner that is an Affiliate of
the General Partner) representing 66.67% of the aggregate Capital Commitments of
all Limited Partners (other than any Defaulting Partners and any Limited Partner
that is an Affiliate of the General Partner).

                  (b) Upon the removal of the General Partner pursuant to

of the General Partner shall be admitted to the Partnership as a Limited
Partner, and (iii) the Partnership shall have the right to terminate upon no
more than thirty (30) days' notice, any management agreements or other
agreements between the Partnership and the General Partner or its Affiliates
(but no such termination shall affect any liability to the Partnership for any
then incurred or accrued Reimbursable Expenses hereunder or any contract
theretofore entered into or obligations theretofore incurred on behalf of or for
the benefit of the Partnership by the General Partner or its Affiliates with any
third parties).

                  (c) The removal of the General Partner pursuant to Section

for any fraud, gross negligence, willful misconduct, or an Event of Default by
the General Partner.

                                   ARTICLE XI

                 TRANSFERABILITY OF A LIMITED PARTNER'S INTEREST

                  SECTION 11.1. Restrictions on Transfer. Prior to 18 months
from the MCT Closing Date, no Transfer of all or any portion of a Limited
Partner's Interest (including some or all of its rights or obligations
hereunder) may be made (other than to an Affiliate of the Limited Partner)
without the prior written consent of the General Partner in its absolute
discretion. After 18 months from the MCT Closing Date, a Limited Partner may
transfer all or a portion of its Interest upon the prior written consent of the
General Partner. If the General Partner does not consent to such Transfer
(unless the General Partner withholds its consent because of evidence that the
proposed transferee has a reputation of committing acts of moral turpitude), the
interest of such Limited Partner in the Partnership shall be redeemed, the
Partnership shall distribute Shares and any other assets to such Limited Partner
in accordance with its Interest Percentage, and within six months of such
distribution the Limited Partner shall pay the Carried Interest with respect to
the Shares distributed. Subject to the Act, no Transfer shall relieve the
transferor of any of its obligations under this Agreement without the written
consent of the General Partner.

                  SECTION 11.2. Expenses of Transfer; Indemnification. All
expenses, including attorneys' fees and expenses, incurred by the General
Partner or the Partnership in connection with any Transfer shall be fully borne
by the transferring Limited Partner or such Limited Partner's transferee. In
addition, the transferring Limited Partner or such transferee shall indemnify
the Partnership and the General Partner in a manner reasonably satisfactory to
the General Partner against any losses, claims, damages, liabilities or expenses
to which the Partnership or the General Partner may become subject arising out
of or based upon any false representation or warranty made by, or breach or
failure to comply with any covenant or agreement of, such transferring Limited
Partner or such transferee in connection with such Transfer.

                  SECTION 11.3.  Recognition of Transfer.

                  (a) The Partnership shall not recognize for any purpose any
purported Transfer of all or any portion of a Limited Partner's Interest
(including some or all of its rights or obligations hereunder) and no transferee
of all or any portion of such Interest shall be admitted as a Limited Partner
hereunder unless:

                  (1) the provisions of Sections 11.1, 11.2 and 11.3(b) shall
         have been complied with;

                  (2) the General Partner shall have been furnished with the
         documents effecting such Transfer, in form and substance satisfactory
         to the General Partner, executed and acknowledged by both transferor
         and the transferee;

                  (3) such Transfer shall have been made in accordance with all
         applicable laws and regulations and all necessary governmental consents
         shall have been obtained and requirements satisfied, including the
         Transfer having been made pursuant to an exemption from the Securities
         Act of 1933 and in compliance with the provisions of New York Corporate
         Securities Law or any other applicable state real estate or securities
         laws or regulations, and such Transfer shall not jeopardize the
         availability of the Partnership's exemption from registration in
         connection with the original offering and sale of Interests referred to
         in Section 12.4(a);

                  (4) such Transfer will not cause a termination of the
         Partnership for federal income tax purposes or cause the

                                       56

<PAGE>



         Partnership to be treated as a publicly traded partnership
         for federal income tax purposes;

                  (5) the books and records of the Partnership shall have been
         changed (which change shall be made as promptly as practicable) to
         reflect the admission of such Limited Partner;

                  (6) all necessary instruments reflecting such admission shall
         have been filed in each jurisdiction in which such filing is necessary
         in order to qualify the Partnership to conduct business or to preserve
         the limited liability of the Limited Partners; and

                  (7) the General Partner shall have received such advice and
         opinions from counsel to the transferor and counsel to the Partnership
         as the General Partner shall deem appropriate to determine that the
         Transfer complies with the requirements of clauses (3) and (4) above.

                  (b) Each transferee, as a condition to its admission as a
Limited Partner, shall execute and acknowledge such instruments, in form and
substance satisfactory to the General Partner, as the General Partner deems
necessary or desirable to effectuate such admission and to confirm the agreement
of such Limited Partner to be bound by all the terms and provisions of this
Agreement with respect to any rights and/or obligations represented by the
Interest acquired by such Limited Partner. The admission of any such Limited
Partner shall not require the approval of any Limited Partner.

                  SECTION 11.4. Transfers During a Fiscal Year. If any Transfer
of a Partner's Interest shall occur at any time other than the end of a Fiscal
Year, the distributive shares of the various items of Partnership income, gain,
loss and expense as computed for tax purposes and the distributions of the
Partnership shall be allocated between the transferor and the transferee
consistent with applicable requirements under Code Section 706; provided that no
such allocation shall be effective unless the transferor and the transferee
shall have agreed to reimburse the General Partner for any incremental
accounting fees and other expenses incurred by the General Partner for any
incremental accounting fees and other expenses incurred by the General Partner
in making such allocation. Neither the General Partner nor the Partnership shall
incur any liability for making allocations and distributions in accordance with
the provisions of this Section 11.4.

Agreement may be amended by the General Partner with the approval of Limited
Partners representing a majority of the aggregate Capital Commitments of all
Limited Partners; provided that no amendment of this Agreement shall:

                  (1) without the approval of all the Limited Partners (other
         than any Defaulting Partners), amend this Section 12.1(a),

                  (2) without the approval of the affected Limited Partner, (w)

         of any Partner (other than as provided in this Agreement), (y) change

         Commitments representing the percentage of Capital Commitments
         specified in any provision of this Agreement required for any action or
         approval of the Partners, amend such provision.

                  SECTION 12.2. Approvals. To the extent permitted by applicable
law, each Limited Partner agrees that the written approval of the Required
Partners shall bind the Partnership and each Limited Partner and shall have the
same legal effect as the written approval of each Partner, for purposes of
granting the approval of the Limited Partners with respect to any proposed
action of the Partnership, the General Partner or any of its Affiliates that
specifically requires such approval.

Interests is intended to be exempt from Registration under the Securities Act of
1933, as amended (the "Securities Act"), by virtue of Section 4(2) of the
Securities Act and that the Partnership will make a notation in its records as

to the effect that the Interests may not be transferred in violation of the
Securities Act;

                  (b) it understands and accepts that the offering and sale of

virtue of a transactional exemption set forth therein;

                  (c) it has such knowledge and experience in business, tax and

merits and risks of an investment in the Interests and to make an informed
investment decision with respect thereto;

                  (d) it is an "accredited investor" within the meaning of Rule
501 under the Securities Act;

                  (e) it is making its investment in the Partnership for its own

Partnership is terminated;

720885.2


<PAGE>



                  (f) it understands that transferability of its Interest is
restricted and the Limited Partner cannot expect to have any liquidity with
respect to its investment;

enter into this Agreement and to perform its obligations hereunder, the person

which the Limited Partner or such person is subject or by which they are bound;

                  (h) unless the General Partner has previously determined that
the admission of the Limited Partner will not cause assets of the Partnership to
be "plan assets" within the meaning of Department of Labor Regulation
ss.2510.3-101, it is not an employee benefit plan subject to Title I of the
Employee Retirement Income Security Act of 1974;

                  (i) it understands that no federal or state agency has

         of trust, loan agreement or similar instrument, any lease or other
         agreement or contract to which it is a party or by which any of its
         property may be bound or any applicable law or order, rule or
         regulation or any court or governmental agency that has jurisdiction

                             (v) there are no actions, suits or proceedings
         pending or, to the knowledge of the General Partner, threatened against
         or affecting the General Partner or, to the knowledge of the General

         the transactions contemplated by this Agreement or might result in a

         governance;

                             (iii) this Agreement is a valid and binding
         obligation of such Limited Partner; and

                             (iv) the execution, delivery and performance of
         this Agreement by it does not conflict with or result in a breach of

                                       63

pledged or otherwise conveyed other than among such individuals or to or for the
benefit of their respective families. Absent death, disability or the consent of
the Required Partners, Ross Dworman and Kenneth F. Bernstein each agree that
they shall commit sufficient attention, time and effort to the management and
operation of the General Partner and through such entity to the management and
operation of the Partnership and its Investments as is then reasonably
appropriate or required in light of the then activities of the Partnership. Ross
Dworman and Kenneth Bernstein will not exercise or transfer (other than due to
death or disability) the Share options described in Section 6.1(e)(v) prior to
36 months after the MCT Closing Date.

                  SECTION 12.7. Successors; Counterparts. This Agreement (i)
shall be binding as to the executors, administrators, estates, heirs and legal
successors of the Partners and (ii) may be executed in several counterparts with
the same effect as if the parties executing the several counterparts had all

                  SECTION 12.8. Governing Law; Severability. This Agreement
shall be governed by and construed in accordance with the laws of the State of
Delaware without giving effect to the principles of conflict of laws thereof. In
particular, it shall be construed to the maximum extent possible to comply with
all of the terms and conditions of the Act. If, nevertheless, it shall be
determined by a court of competent jurisdiction that any provision or wording of
this Agreement shall be invalid or unenforceable under said Act or other
applicable law, such invalidity or unenforceability shall not invalidate the
entire Agreement. In that case, this Agreement shall be construed so as to limit
any term or provision so as to make it enforceable or valid within the
requirements of applicable law, and, in the event such term or provision cannot
be so limited, this Agreement shall be construed to omit such invalid or
unenforceable provisions. If it shall be determined by a court of competent
jurisdiction that any provision relating to the distributions and allocations of
the Partnership or to any fee payable by the Partnership is invalid or
unenforceable, this Agreement shall be construed or interpreted so as (i) to
make it enforceable or valid and (ii) to make the distributions, allocations and
fees as closely equivalent to those set forth in this Agreement as is
permissible under applicable law.

                  SECTION 12.9.  Filings.  Following the execution and
delivery of this Agreement, the General Partner shall promptly
prepare any documents required to be filed and recorded under the
Act, and the General Partner shall promptly cause each such

                                       64

to time be required by the laws of the United States of America, the State of
Delaware or any other state, or any political subdivision or agency thereof, to
effectuate, implement and continue the valid and subsisting existence of the
Partnership or to dissolve the Partnership.

                  The power of attorney granted hereby is coupled with an
interest and shall (a) survive and not be affected by the subsequent death,
incapacity, disability, dissolution, termination or bankruptcy of the Limited
Partner granting the same or the transfer of all or any portion of such Limited
Partner's Interest and (b) extend to such Limited Partner's successors, assigns
and legal representatives.

                     TO THE AGREEMENT OF LIMITED PARTNERSHIP
                            OF RD PROPERTIES, L.P. VI

             SCHEDULE OF REIMBURSABLE EXPENSES, PROPERTY MANAGEMENT
           FEES, LEASING FEES AND OTHER TRANSACTION FEES (ss. 3.5(B))
                            (as of November 1, 1997)


         A. Reimbursable Expenses. The following expenses ("Reimbursable
Expenses"), to the extent they are related to an Investment, shall be reimbursed
by the Partnership to the General Partner to the extent actually incurred by the
General Partner or its designated Affiliate:

                  Any expense that would have constituted a Partnership Expense
                  (as defined in Section 3.5 of the Agreement), but which the
                  General Partner or its Affiliate paid or incurred directly;
                  travel costs to and from any Investments located outside of
                  the New York metropolitan area; costs of travel and lodging
                  associated with any Investment or the conducting of any
                  business of the Partnership outside of the New York
                  metropolitan area; telephone and telecopy expenses; postage;
                  photocopy expenses; courier expenses and similar expenses.

The legal fees and costs associated with the drafting and formation of the

It is understood that the Partnership may be reimbursed for some of such
expenses from tenants under the leases for space in some Investments.

         B. Transaction Fees. The following expenses ("Transaction Fees"), to
the extent they relate to an Investment, shall be paid by the Partnership to the
General Partner or its designated Affiliate in the manner and amount provided
herein: Leasing Fees; Property Management Fees; and Construction/Project

         C.       Leasing Fees and Related Reimbursable Expenses.
                  
                  (a) During the term of the Partnership, in consideration for
the General Partner's or its designated Affiliate's supervision and management
of the Partnership's leasing activities for such Investment, the Partnership
shall pay to the General Partner or its designated Affiliate the leasing fees
hereinafter described ("Leasing Fees") with respect to each (i) lease for space
in an Investment ("Lease"), (ii) extension or renewal of the term of a Lease, or
(iii) expansion of the premises leased under a Lease (collectively, a "Leasing
Event"), entered into by the Partnership during the term of the Partnership. The
Partnership shall pay to the General Partner or its designated Affiliate any
Leasing Fees payable hereunder within ten (10) day following the end of the
month during which full execution of the document giving effect to the Leasing
Event occurred.

                  (b) As used in this Paragraph C, the term "Standard
Commission" shall have the following meaning: (i) with respect to each new
Lease, including any Lease or any amendment relating to expansion of the
premises leased under a Lease, (A) for any retail or commercial Lease, 5.0%, or
6.0% on any co-brokered retail or commercial Lease, (not including any
pass-through charges such as common area maintenance charges, insurance premiums
or taxes that the tenant under such Lease may be obligated to pay or any future
percentage rent) (the "Base Rent") required to be paid by the tenant under such
Lease during the period from the commencement of the original term of such Lease
(the term for this purpose shall be deemed to commence on the commencement of
the tenant's rental obligation under the lease after any rent-free buildout
period or other free rent period) through the end of the first to occur of the
end of the first ten (10) years of such term or the end of the initial term of
such Lease, and (B) if the initial term of the Lease is longer than ten years,
two and one-half percent (2.5%) of the Base Rent required to be paid by the
tenant under such Lease during the period from the eleventh year of such term
through the first to occur of the end of the fifteenth year of such term or the
end of the initial term of such Lease, and (ii) with respect to each extension
or renewal of the term of any lease ("Renewal"), one half of the amount that
would be calculated under clause (i) immediately above with respect to each such
Renewal if the term of such Renewal were treated as an initial term and the rent
payable during such Renewal were treated as the Base Rent payable during such
initial term.

                  (c) With respect to any Leasing Event, the Partnership shall
pay the following leasing Fees to the General Partner or its designated
Affiliate:

720885.2
                                       D-2

<PAGE>



                           (i)  If the Leasing Event occurred solely with the
assistance of a listing broker other than the General Partner or an Affiliate
thereof and with no assistance from the General Partner or an Affiliate thereof,
there shall be no Leasing Fees.

                           (ii) If the Leasing Event occurred with the
General Partner or an Affiliate thereof acting as the broker with or without the
assistance of either a listing broker or a procuring broker (other than the
General Partner or an Affiliate thereof), then the General Partner (or such
Affiliate) shall be entitled to the Standard Commission in connection with such
Leasing Event, provided that the Standard Commission payable to the General
Partner or its Affiliates shall be payable based upon the Standard Commission
with respect to the first $100,000 of commission for a Leasing Event but (A) be
reduced in any co- brokered transaction to 1.5% with respect to the portion, if
any, of the commission payable to the General Partner or its Affiliates for such
transaction which would exceed $100,000 without applying this proviso and (B)
shall be reduced in any transaction other than a co-brokered transaction to 3%
with respect to the portion, if any, of the commission for such transaction
payable to the General Partner or its Affiliates which would exceed $100,000
without applying this proviso. In addition, any leasing commission payable to
the General Partner or its Affiliates in excess of $100,000 shall be payable
only after the General Partner has consulted with the Advisory Committee
concerning whether the amount of such commission is consistent with an
arm's-length commission.

                  The Leasing Fees so payable to the General Partner or the
designated Affiliate shall be determined as provided above, without regard to
whether (i) any commissions then payable to any procuring broker (other than the
General Partner or any Affiliate thereof) are based upon a commission schedule
that is structured differently, or (ii) any particular Leasing Event would
provide for a third party leasing commission to any other participating broker
greater or less than the corresponding Leasing Fees payable to the General
Partner or its designated Affiliate hereunder.

                  (d) In addition to the Leasing Fees the Partnership (and not
the General Partner or any of its Affiliates) shall be responsible for, and if
incurred by the General Partner or any of its Affiliates, the Partnership shall
reimburse the General Partner or its Affiliates for the following costs and
expenses (the "Leasing Reimbursable Expenses"): (i) all costs incurred in
connection with the marketing or the leasing of the space in the Investment,
including without limitation, all leasing signs, brochures, floor plans,
renderings and space plans, and (ii) all payments due and owing to third party
listing brokers or

720885.2
                                       D-3

procuring brokers. All of the Leasing Reimbursable Expenses payable to the
General Partner or any of its Affiliates shall be paid by the Partnership within
ten (10) days following the end of the month in respect of which the Leasing
Reimbursable Expenses were incurred or paid.

                  (e) The General Partner will cause its Affiliate which
provides leasing and management services to provide to the Advisory Committee at
least annually, financial statements of such Affiliate, which include the
Affiliate's gross revenue and gross expenses.

         D.       Property Management Fee.

                  (a) During the term of the Partnership, in consideration for
the General Partner's or its designated Affiliate's performance of property
management services as to any Investment (for which management the Partnership
has not engaged a management company other than the General partner or its
designated Affiliate), the Partnership shall pay to the General Partner or its
designated Affiliate an amount (the "Property Management Fee") equal to 4.0% of
Gross Revenues with respect to retail and commercial properties and 4.5% of
Gross Revenues with respect to residential properties, during the Partnership's
ownership of the Investment. The Property Management Fee shall be payable
monthly in arrears within ten (10) days after the last day of each calendar
month (prorated for any partial calendar month).

                  (b) "Gross Revenues" means with respect to a particular
Investment all revenues derived from such Investment, but excluding (i) security
deposits made by tenants in such Investment (except to the extent that such
security deposits are applied to rent and other amounts payable by tenants of
such Investment), (ii) proceeds from the sale or financing of such Investment,
(iii) proceeds from insurance or condemnation with respect to such Investment
(except to the extent such proceeds are payments for lost rents or other amounts
payable by tenants of such Investment), (iv) all federal, state and local
excise, sales, use or rent taxes (other than such real property taxes and other
taxes which are payable to the landlord as operating expenses by tenants under
Leases), and (v) Capital Contributions made by the Partners to the Partnership
in respect of such Investment.

                  (c) Fees with respect to Investments that are debt obligations
shall be paid to the extent the General Partner or an Affiliate perform services
with respect to such Investments, in an amount equal to the cost incurred by the
General Partner or its Affiliate in performing such services.

         E. Construction/Project Management Fee. During the term of the
Agreement, in consideration for the General Partner's or its designated
Affiliate's performance of construction or project management services that the
General Partner or its designated Affiliate, after consultation with the
Advisory Committee, elects to perform (rather than causing the Partnership to
retain a separate construction or project manager), with respect to any
Investment, the Partnership shall pay to the General Partner or its designated
Affiliate an amount (the "Construction/Project Management Fee") equal to 7.5% of
the hard costs for the construction project ("Construction Project") whether for
retail, commercial or residential space. If the Construction/Project Management
Fee is not to be a fixed fee but rather is to be based on the Construction Costs
of a Construction Project, then, "Construction Costs" shall mean the total
construction costs to the Partnership of all elements of the Construction
Project managed by the General Partner or its designated Affiliate, including,
without limitation, all architect's and engineering fees, and all amounts
payable to contractors and subcontractors with respect to the Construction
Project; provided, however, that Construction Costs shall not include the
Construction/Project Management Fee.

         F. Legal Fees. During the term of the Agreement, in consideration for
the General Partner's or its designated Affiliate's performance of any legal
services that the General Partner or its designated Affiliate, performs through
an attorney, with respect to any Investment, the Partnership shall pay to the
General Partner or its designated Affiliate an amount (the "Legal Fee") equal to
$175.00 per hour, plus expenses. This fee may be increased by the General
Partner, upon prior notification to the Advisory Committee, by up to 4% per
year.

         G. Financing Fees. In lieu of an outside mortgage banker, the General
Partner may cause an Affiliate to provide mortgage banking services. In such
event, the services shall be provided at cost and subject to reasonable prior
approval of the Advisory Committee.

require different reporting, in which case the Limited Partners requiring such

                  SECTION 3.7.  Tax Matters Partner.

                  (a) The General Partner is hereby designated as the "tax
matters partner" of the Partnership as defined in Section 6231 of the Code, and
any successor provisions (the "Tax Matters Partner").

                  (b) The Tax Matters Partner shall give prompt notice to the

                  (a) Partnership meetings shall be held at the Partnership's
principal executive office (unless another address is duly noticed by the

the General Partner or, (ii) as respects any matter on which the Limited
Partners may vote or are required to be consulted or to consent, when called by
any Limited Partners representing more than ten percent (10%) of the aggregate
Interest Percentages held by all of the Limited Partners. Notice of a meeting
shall be given in accordance with the provisions of Section 12.15, unless such

                  (b) Any action which may be taken at any meeting of the
Partners may be taken without a meeting if a consent in writing, setting forth

at which all Partners entitled to vote thereon were present and voted. Any
written solicitation for the consent of any Limited Partner to the taking of any
action shall be simultaneously forwarded by the General Partners to all of the

would be necessary to authorize or take that action at a meeting at which all
Partners entitled to vote thereon were present and voted.


                                                    ARTICLE IV

                                     INVESTMENTS AND INVESTMENT OPPORTUNITIES

                  SECTION 4.1.  Investments Generally.

                  The assets of the Partnership shall consist solely of the
Shares, and any cash from time to time distributed to the Partnership with
respect thereto which may be invested pending distribution to the Partners as
set forth hereunder.

                  SECTION 4.2. Partner Investments. Nothing in any other
provision of this Agreement shall limit the right of the Partners or any of
their Affiliates, and each of them shall be permitted without first having
consulted with any other Partner, to engage in or conduct any other business.

                  SECTION 4.3.  Additional Rights of Limited Partner with
Respect to the Investment.

                  (a)  Right of First Preference for Preferred Stock.

                  (i) If, following the Closing Date, Mark Centers Trust has an
offering of preferred stock convertible into common shares of beneficial
interest of Mark Centers Trust (the "Offered Stock"), it has agreed, pursuant to
the Contribution Agreement, to use its commercially reasonable efforts to
provide each

704007.16
                                      -14-



<PAGE>



Limited Partner and the limited partners of the Sister Partnerships
(collectively, with the Limited Partners, the "Sister LPs" and individually, a
"Sister LP") with a right of first preference to purchase the first offering or
offerings with respect to an aggregate of $75 million (the "Offering") of such
Offered Stock which occurs subsequent to the Closing Date, on terms and
conditions which will be identical to the offer and sale of such Offered Stock
to investors other than the Sister LPs. Notwithstanding the foregoing, up to $10
million of the Offering may be reserved for persons other than the Sister LPs.
If the Offering is increased to up to $90 million, the excess of the amount of
the Offering over $75 million may also be reserved for Persons other than the
Sister LPs, and if the Offering is increased to above $90 million, the right of
first preference to purchase shares of Offered Stock in favor of the Sister LPs
shall equal the sum of (I) $65 million and (II) the lesser of (A) $10 million
and (B) the excess of (i) the amount of the Offering over (ii) $90 million.

                  (ii) The Partners hereby acknowledge that the terms of the
Offered Stock will be subject to the discretion of Mark Centers Trust.
Notwithstanding the foregoing, the General Partner, as authorized in the
Contribution Agreement, hereby grants to each Limited Partner and agrees that
each Limited Partner shall have the right, and agrees to use its best efforts to
cause Mark Centers Trust to offer to each Limited Partner the right to acquire
at least its pro rata share of the Offered Stock. The General Partner hereby
agrees that the Sister LPs shall have the right to acquire the Offered Stock in
accordance with the following procedures:

                  1. If any Limited Partner and any or all of the other Sister
                  LPs elect to acquire all or any portion of the Offered Stock,
                  then such Limited Partner may acquire up to its pro rata share
                  of the Offered Stock. Such pro rata share shall be determined
                  by multiplying the number of shares of Offered Stock times a
                  fraction, the numerator of which is the number of Shares
                  acquired by the Partnership and the denominator of which is
                  the aggregate number of Shares and common shares of beneficial
                  interest of Mark Centers Trust acquired by the Partnership and
                  the Sister Partnerships, and then applying each Limited
                  Partner's Interest Percentage to such amount.

                  2. If any Sister LP elects not to purchase all or any portion
                  of its pro rata share of the Offered Stock, the General
                  Partner will use its best efforts to cause Mark

704007.16
                                      -15-



<PAGE>



                  Centers Trust to offer to each Limited Partner and Sister LPs
                  which have agreed to purchase Offered Stock the right to
                  purchase some or all of the remaining Offered Stock. The
                  Limited Partners and those Sister LPs desiring to purchase
                  additional shares of Offered Stock may purchase up to their
                  pro rata share as determined above (but excluding from the
                  calculation the Interest Percentage of any Limited Partner
                  which has not agreed to purchase Offered Stock) of the
                  remaining Offered Stock until such remaining Offered Stock is
                  either purchased or the Limited Partner or the other Sister
                  LPs no longer desire to purchase such Offered Stock.

                  3. A Limited Partner may condition its offer to acquire
                  Offered Stock on the purchase of a minimum number of shares or
                  dollar amount of Offered Stock, and may acquire less shares of
                  Offered Stock than its pro rata share.

                  (b) Registration Rights. Reference is made to the form of
Registration Rights and Lock-Up Agreement attached as Exhibit E to the
Contribution Agreement (the "Registration Rights Agreement"). To the extent the
final Registration Rights Agreement entered into on the Closing Date does not
provide that the rights of the Partnership thereunder are automatically
assignable to transferees of the Shares, the General Partner, on behalf of the
Partnership, hereby agrees to assign such rights to the Limited Partners upon
any distribution of the Shares from the Partnership and the General Partner will
cause the Partnership to execute and deliver any and all documents necessary to
effect such assignment. The General Partner hereby warrants that under the terms
of the Registration Rights Agreement such rights are so assignable.

                  (c) Tag-Along Rights. (i) If the General Partner or any
Affiliate of the General Partner (collectively with the General Partner, a "GP
Affiliate") desires to sell or otherwise dispose of (other than a pledge in
connection with a borrowing) any common shares of beneficial interest of Mark
Centers Trust, options to purchase common shares of beneficial interest of Mark
Centers Trust (not including the exercise of employee stock options granted to
such GP Affiliate who is an officer or trustee of MCT), operating partnership
units of Mark Centers Limited Partnership or other securities convertible into
or exchangeable for common shares of beneficial interest of Mark Centers Trust
(collectively, "MCT Securities") held by it to any other Person other than a GP
Affiliate (a "Third Party Sale"), the GP

704007.16
                                      -16-



<PAGE>



Affiliate shall, at least thirty (30) Business Days prior to the proposed
closing date of such Third Party Sale, give written notice to the Limited
Partners describing such Third Party Sale in reasonable detail including the
price offered and all material terms and conditions of the Third Party Sale.

                  (ii) Each Limited Partner shall have the right and the option,
by written notice given to the selling GP Affiliate within fifteen (15) Business
Days prior to the closing of such Third Party Sale, to sell in such Third Party
Sale the same percentage of the total number of Shares held by the Limited
Partner (which for this purpose shall mean Shares held by the Limited Partner
and Shares held by the Partnership for the account of the Limited Partner) (or
direct the Partnership to sell such number of Shares) as the number of MCT
Securities to be sold by the selling GP Affiliate represents to all MCT
Securities held by such GP Affiliate.

                  (iii) In the event a Third Party Sale is proposed, the right
granted under this Section 4.3(c) shall be exercisable by the Partnership at the
written request of the Limited Partner.

                  (d) Pre-emptive Rights. In the event that any GP Affiliate
receives pre-emptive rights to acquire MCT Securities (the "Pre-emptive
Rights"), such GP Affiliate shall grant to the Limited Partners and/or use its
best efforts to cause Mark Centers Trust (or other grantor of Pre-emptive
Rights) to grant to each Limited Partner and the other Sister LPs Pre-emptive
Rights to acquire, at terms no less favorable than those offered to the GP
Affiliates, the same aggregate number of MCT Securities as are subject to the
Pre-emptive Rights offered to such GP Affiliates. Of such Pre-emptive Rights to
be granted to the Sister LPs, each of the Limited Partners shall be entitled to
acquire its pro rata share of such MCT Securities. Such pro rata share shall be
determined in the same manner as is set forth in Section 4.3(a)(ii).

                  (e) Pass-through of Right to Purchase. In the event that Mark
Centers Trust commences a rights offering for any securities or other similar
offering of rights or securities to its shareholders, the Limited Partner may
exercise the rights granted to shareholders of Mark Centers Trust, as if it were
a shareholder with respect to the Shares not otherwise previously distributed to
it pursuant to this Agreement; provided the cost of exercising such rights shall
be paid directly by the Limited Partner.

                  (f) Voting Proxy. Notwithstanding anything else contained in
this Agreement, the General Partner hereby constitutes and appoints each Limited
Partner its true and lawful attorney, agent and proxy to exercise all voting
rights of shareholders of Mark Centers Trust with respect to the number of
Shares owned by the Partnership which would otherwise be distributable to the
Limited Partner if the Partnership were liquidated.

                  (g) Any purchase of securities pursuant to Sections 4.3(a),
(d) and (e) hereof (i) which are required to be purchased in the name of the
Partnership, shall be purchased by the Partnership (upon a contribution of cash
by the Limited Partner therefor) and shall immediately be distributed by the
Partnership to the Limited Partner, (ii) shall not be deemed property of the
Partnership and (iii) shall not be subject to the provisions of this Agreement,
including without limitation, the provisions relating to the Preferred Return,
Carried Interest or distributions.

                  (h) The provisions of Section 4.3(c) through (f) shall
terminate at the earlier to occur of (i) the termination or dissolution of the
Partnership and (ii) thirty (30) months after the Closing Date (collectively,
the "Expiration Date"). The provisions of Section 4.3(a) shall survive the
termination or dissolution of the Partnership only if an offering of Offered
Securities has not occurred prior to the Expiration Date and the General Partner
will do whatever is necessary to confirm the continuation of such rights to the
Limited Partners. The provisions of Section 4.3(b) shall survive the termination
or dissolution of the Partnership.

                  SECTION 5.1.  Capital Contributions.

                  (a) Each Partner hereby agrees to make Capital Contributions
to the Partnership in the amount set forth on Schedule B on or before five

Partner may pursue any remedies available to the Partnership, in law or at
equity, against any Partner who fails to make a Capital Contribution as required
pursuant to this Agreement, including the commencement of an action seeking
specific performance and/or damages, and after the closing of the transactions
contemplated by the Contribution Agreement, if the Limited Partner has failed to
make all or a portion of its Capital Contribution, the General Partner's rights
hereunder to pursue such remedies may be exercised by Mark Centers Trust
directly. Notwithstanding the foregoing, the Partners shall not be obligated to
make Capital Contributions as described herein if (i) there is an amendment to
the Contribution Agreement that could reasonably be expected to be materially
adverse to the Investment, or any Limited Partner or the Partnership, or (ii)
the General Partner (or an Affiliate of the General Partner) waives a condition
to closing under the Contribution Agreement which could reasonably be expected
to be materially adverse to the Investment, any Limited Partner or the
Partnership. For purposes hereof, any change to (i) the purchase price per
Share, (ii) the aggregate amount to be invested by all of the Sister
Partnerships in excess of $120 million, (iii) the aggregate number of and
percentage of the outstanding shares of beneficial interest of Mark Centers
Trust represented by the Shares to be purchased, as compared with such number
and percentage assuming a purchase by the Partnership and the Sister
Partnerships of 16 million Shares at $7.50 per share, (iv) the right of first
preference to purchase Offered Stock, shall be deemed to be materially adverse,
or (v) any increase over $25 million in the aggregate amount of Offered Stock
offered to, or reserved for, any person other than the Limited Partners and the
Sister LPs. Once a Limited Partner has made its Capital Contribution pursuant to
this Section 5.1, it shall have no further obligation to make any contributions
to the capital of the Partnership.

                  (b) If the closing under the Contribution Agreement does not
occur for any reason by the earlier of December 31, 1998 and the termination of
the Contribution Agreement, the General Partner shall promptly, and in no event
later than two (2) Business Days after the earlier of such date and the
termination of the Contribution Agreement, pay to each Limited Partner an amount
equal to each Limited Partner's Capital Contribution plus interest earned
thereon in immediately available funds to an account designated by the Limited
Partner, and the Limited Partner shall be released from and have no further
obligations hereunder.

                  SECTION 5.2.  Temporary Investment of Funds.  The
General Partner shall invest all cash held by the Partnership in

or guaranteed by the United States or its agencies or instrumentalities maturing
within six months or less from the date of acquisition, (ii) commercial paper
rated P-1 or A-1 on the date of acquisition and maturing within six months or
less from the date of acquisition, (iii) overnight time deposits or other
interest-bearing deposits (whether or not insured) in national or state banks
(a) having capital and surplus of at least $1,000,000,000 and having a long-term

at least $750,000,000 and investments comprised of debt with a credit rating of
A1 or P1 or a substantially similar rating and (v) similar quality short-term
investments. Notwithstanding the foregoing, it is not expected that the
Partnership will retain any material cash balances. Any interest earned on
investments pursuant to this Section 5.2 shall be payable to the Partners pro
rata in accordance with their Interest Percentage in the event the Closing does
not occur or shall be added to the Capital Contributions made hereunder, pro
rata in accordance with the Partners' Interest Percentage and shall be applied
first to pay Partnership Expenses and second to purchase Shares.

         of such distribution; and

                  (d)  Intentionally Deleted.

                       then the Partnership will be dissolved in accordance
         with Article IX.

                           (iii) If during the term of this Agreement any Shares
         are distributed to any Limited Partner, the following provisions shall
         apply:

                             (A) The distribution of such Shares shall not
                       reduce the Limited Partner's Unreturned Capital or
                       Interest Percentage or otherwise be treated as a
                       distribution pursuant to this Agreement.

                             (B) Any cash received by the Limited Partner in
                       respect of such Shares, whether dividends or net proceeds
                       of sale, shall be deemed to have been received by the
                       Partnership and shall be deemed to have been distributed
                       to the Partners pursuant to Section 6.1(a) for all
                       purposes of this Agreement;

                       and the Limited Partner shall pay to the General Partner
                       any amount of the deemed distribution then made to the
                       General Partner.

                             (C) If on a date which is the earlier of 60 months
                       after the Closing Date and a date selected by any Limited
                       Partner (which shall be 36 months or more after the
                       Closing Date), a Limited Partner shall be holding Shares
                       previously distributed to it by the Partnership, the Fair
                       Market Value of such Shares, net of brokerage or
                       underwriting commissions that would be incurred if such
                       Shares then held by such Limited Partner were then sold,
                       shall be deemed to have been received by the Partnership
                       and the provisions of Section 6.1(e)(iii)(B) shall apply
                       to such amount. Any amount due to the General Partner as
                       a result of its deemed distribution pursuant to this
                       subsection 6.1(e)(iii)(C) shall be paid by the Limited
                       Partner to the General Partner in cash or in Shares, as
                       elected by the Limited Partner. Each Limited Partner will
                       consider, but is not obligated with respect to, a request
                       from the General Partner for the Carried Interest to be
                       paid to the General Partner in Shares.

                             (D) In order that the provisions of Section
                       6.1(e)(iii)(B) can be effectuated, each Limited Partner
                       shall give the General Partner notice each time such
                       Limited Partner sells any Shares distributed to it by the
                       Partnership, and in such notice shall set forth the
                       amount of the net proceeds received by the Limited
                       Partner upon said sale. The obligations of the Limited
                       Partners under Section 6.1(e)(iii)(D) shall terminate on
                       the earliest of 60 months after the Closing Date, the
                       date on which Shares held by such Limited Partner are
                       valued pursuant to Section 6.1(e)(iii)(C) and the date on
                       which all Shares held by such Limited Partner and held by
                       the Partnership in which such Limited Partner has an
                       interest have been sold.

                            (iv) The Carried Interest will remain in effect with
         respect to distributed Shares until sixty months after the Closing Date
         (or the date selected by the Limited Partner in accordance with clause
         (c), above). At the time each Limited Partner determines to sell
         Shares, each Limited Partner will consider, but is not obligated with
         respect to, a request from the General Partner for the Carried Interest
         to be paid to the General Partner in Shares.

                             (v) Whenever any distribution or deemed
         distribution is to be made to the General Partner pursuant to Section
         6.1(a)(iii) and/or Section 6.1(e)(iii) by reason of the sale of any
         Shares by the Partnership or a Limited Partner or pursuant to Section
         6.1(e)(iii)(C), such distribution or deemed distribution shall be
         reduced to reflect (A) the aggregate "value" on the date of the
         distribution or deemed distribution of the Share options in Mark
         Centers Trust held by and/or previously exercised by Ross Dworman
         and/or Ken Bernstein, (B) any extraordinary compensation that has been
         paid by Mark Centers Trust to Ross Dworman and/or Ken Bernstein (i.e.,
         bonus compensation in excess of amounts customarily paid to executive
         officers of public real estate investment trusts, as reasonably
         determined by the Limited Partners and (C) the net present value,
         calculated using a discount rate equal to Treasury Securities of
         similar maturity, of amounts payable by Mark Centers Trust to Ross
         Dworman and/or Kenneth Bernstein as a result of a change in control (as
         defined in any agreement between Mark Centers Trust and either Ross
         Dworman or Kenneth Bernstein) of Mark Centers Trust (the "Excess
         Compensation")). The distribution or deemed distribution to the General
         Partner will be reduced by an amount equal to (a) the "value" of all
         vested Share options held by and/or previously exercised by Ross
         Dworman and Ken Bernstein and the Excess Compensation multiplied by (b)
         a fraction, the numerator of which is the number of Shares sold by the
         Partnership or such Limited Partner or the number of Shares of such
         Limited Partner being valued and the denominator of which is all of the
         issued and outstanding shares of Mark Centers Trust and units of Mark
         Centers Limited Partnership, on a fully diluted basis. For purposes of
         this calculation, the "value" of the share options shall be determined
         using the Black-Scholes method for unexercised options and shall be the
         excess of the closing market price on the date of exercise of each
         option of shares acquired pursuant to options over the purchase price
         of such shares, for exercised options.

                  SECTION 6.2. Preferred Return. No later than nor less
frequently than the thirtieth (30th) day following the close of each fiscal
quarter, the General Partner shall determine, based on a statement of operations
and cash flow for the Partnership, which need not be audited, and distribute to
the Partners to the extent of Distributable Proceeds, pro rata in accordance
with their respective amounts of Unreturned Capital, an amount, in the
aggregate, equal to eight percent (8%) per annum of the average monthly balance
of such Partners' aggregate Unreturned Capital (the "Preferred Return")since the
last distribution of Distributable Proceeds. To the extent the Partnership is
unable to make a Preferred Return payment pursuant to this Section 6.2 in any
quarter, the unpaid amount of the Preferred Return will be compounded
semiannually at a rate of 8% per annum and paid in future quarters. No amounts
shall be distributed to Partners pursuant to Section 6.1 (other than Section
6.1(a)(i)) if any Preferred Return amount required to be paid under this Section
6.2 is accrued but unpaid. Amounts paid pursuant to this Section 6.2 are
intended to constitute payments of a preferred return for capital within the
meaning of Treasury Regulations ss. 1.514(c)- 2(d)(2) and not guaranteed
payments within the meaning of Section 707(c) of the Code.

                  SECTION 6.3.  Capital Accounts.  (a)  There shall be
established for each Partner on the books and records of the
Partnership an account (a "Capital Account"), which shall
initially be zero and which shall be adjusted as follows:

                             (i) The amount of cash contributed to the
         Partnership by each Partner shall be credited to the Capital Account of
         such Partner.

                            (ii) The amount of cash (or the fair market value of
         other property as determined by the General Partner pursuant to this
         Article VI, net of any liabilities assumed or taken subject to by the
         Partners) distributed by the Partnership to each Partner shall be
         debited against the Capital Account of such Partner.

                           (iii) The Net Income and Net Loss of the Partnership
         (and the items entering into the determination thereof) allocated to
         each Partner pursuant to this Article VI shall be credited to and
         debited against, respectively, the Capital Account of such Partner.

                       (b)  If all or any portion of an Interest is
transferred in accordance with this Agreement, the transferee

704007.16
                                      -25-



<PAGE>



shall succeed to the Capital Account of the transferor to the extent it relates
to the transferred Interest or portion thereof.

                       (c)  The provisions of this Agreement relating to
the maintenance of Capital Accounts are intended to comply with applicable
Regulations under Code Section 704 and to provide for allocations which have
"substantial economic effect" within the meaning of those Regulations and shall
be interpreted and applied in a manner consistent with this intention.

                  SECTION 6.4.  Allocations of Net Income and Net Loss.

                  (a) Net Income. Except as otherwise provided in this Article
VI, Net Income for each Fiscal Year shall be allocated in the following order:

                             (i) first, if any Net Loss has been previously
         allocated to the Partners, reversing the prior allocations of Net Loss
         on a most recent in time basis until the cumulative amount allocated
         pursuant to this Section 6.4(a)(i) equals the cumulative amount of Net
         Loss previously so allocated; and

                            (ii) second, to the Partners in an amount equal to
         the distributions made to each Partner (or which would be made to each
         Partner, if the Partnership distributed cash in an amount equal to such
         Net Income) pursuant to Section 6.1(a).

                  (b) Net Loss. Except as otherwise provided in this Article VI,
Net Loss for each Fiscal Year shall be allocated first, if any Net Income has
previously been allocated to the General Partner with respect to its Carried
Interest, to the General Partner in an amount equal to such Net Income and then
to the General Partner and the Limited Partners in proportion to their Interest
Percentages.

                  (c) Miscellaneous. Any Net Income or Net Loss allocated to the
Limited Partners shall be allocated among the Limited Partners pro rata in
accordance with their Interest Percentages.

                  SECTION 6.5.  Other Allocations.

                  (a)  Other Allocation Rules.

                             (i) To the extent required by Code Section 704 and
         the Regulations thereunder, income, gain, loss,

704007.16
                                      -26-



<PAGE>



         deduction and credit with respect to any property shall, solely for tax
         purposes (and not for purposes of maintaining the Capital Accounts
         hereunder), be allocated among the Partners so as to take account of
         any variation between the adjusted basis of such property for federal
         income tax purposes and its 704(c) Value. Any elections or other
         decisions relating to such allocation shall be made by the General
         Partner with the consent of the Required Partners.

                  "704(c) Value" means, with respect to any Partnership asset,
the adjusted basis for federal income tax purposes of such asset, adjusted as of
the following times to equal its gross fair market value (as determined by the
General Partner in its discretion): (a) the acquisition of an additional
Interest by any new or existing Partner in exchange for more than a de minimis
(as that term is used in Regulation Section 1.704-1(b)(2)(iv)(f)) Capital
Contribution; (b) the distribution by the Partnership to a Partner of more than
a de minimis amount of Partnership property or money if the General Partner
determines in its discretion that such adjustment is necessary or appropriate to
reflect the economic interests of the Partners in the Partnership; and (c) the
liquidation of the Partnership for federal income tax purposes within the
meaning of Regulation Section 1.704(b)(2)(ii).

                  SECTION 6.6. Tax Allocations. All items of income, gain, loss,
deduction or credit of the Partnership shall be allocated among the Partners for
federal income tax purposes in a manner consistent with the allocation of the
corresponding items to the Partners under the other provisions of this Article
VI.

                  SECTION 6.7. Distributions in Kind. The General Partner may
distribute any property constituting all or any portion of an Investment in
kind. Any property so distributed shall be deemed for purposes of determining
Net Income or Net Loss under this Article VI to have been sold by the
Partnership for an amount equal to its Fair Market Value (calculated in United
States dollars). Except as provided in Section 6.1(e), in any distribution of
property in kind, the General Partner shall not, without the consent of all the
Limited Partners, discriminate among Partners and shall endeavor to (i)
distribute to each applicable Partner a proportional interest in any particular
property in accordance with this Article VI and (ii) if cash and property in
kind are to be distributed simultaneously in respect of any Investment,
distribute cash and property in kind in the same proportion to each applicable
Partner.

<PAGE>



                  Notwithstanding the foregoing, if any Limited Partner notifies
the General Partner that such Limited Partner is prohibited by applicable law or
regulation from holding directly the property to be distributed in kind, the
General Partner shall, in lieu of making such distribution in kind to such
Limited Partner and to the extent permitted by applicable law, use commercially
reasonable efforts to sell such property on such Limited Partner's behalf, on
terms acceptable to such Limited Partner and, upon such sale, the General
Partner shall promptly distribute to such Limited Partner the net proceeds of
such sale.

                  SECTION 6.8. Setoff and Withholding of Certain Amounts.
Notwithstanding anything else contained in this Agreement, the General Partner
may in its discretion set off against, or withhold from, any distribution to any
Partner pursuant to this Agreement, the following amounts:

                       (a) any amounts due from such Partner to the Partnership
         or the General Partner pursuant to this Agreement to the extent not
         otherwise paid,

                       (b) any amounts required to pay or reimburse (x) the
         Partnership for the payment of any withholding or other taxes properly
         attributable to such Partner or (y) the General Partner for any
         advances made by the General Partner for such purpose.

                  Any amounts so set off or withheld pursuant to this Section
6.8 shall be applied by the General Partner to discharge the obligation in
respect of which such amounts were withheld. All amounts set off or withheld
either pursuant to this Section 6.8 or pursuant to the Code or any provision of
any state or local tax law attributable to any Partner shall be treated as
amounts distributed to such Partner for all purposes under this Agreement.

                  SECTION 6.9.  Withdrawal and Return of Capital.  Except
                                --------------------------------
as specifically provided in this Agreement, a Partner shall not
have any right to demand the return of any Capital Contribution
or to withdraw any portion of Partnership capital.  If the
Distributable Proceeds remaining upon dissolution of the
Partnership after the payment or discharge of Partnership
Expenses are insufficient to return any Partner's Unreturned
Capital, the Partner shall have no recourse against any of the
Partners or against the Partnership.

                  SECTION 6.10.  Deemed Partnerships.  Notwithstanding
anything to the contrary set forth in this Article VI or

704007.16
                                      -28-



<PAGE>



elsewhere in this Agreement, for the purposes of calculating amounts to be
distributed or to be deemed to have been distributed to the Partners pursuant to
this Article VI or Article IX, it shall be deemed that the Partnership
constitutes four separate partnerships, each of which is between the General
Partner and one of the Limited Partners (each a "Deemed Partnership"). The
Interest Percentage of the General Partner in a Deemed Partnership shall be the
Interest Percentage of the General Partner in the Partnership multiplied by the
Interest Percentage of the Limited Partner of such Deemed Partnership in the
Partnership. The Interest Percentage of the Limited Partner in a Deemed
Partnership shall be 100% less the Interest Percentage of the General Partner
therein. There shall be deemed owned by each Deemed Partnership on the Closing
Date a number of Shares equal to the number of Shares acquired by the
Partnership on the Closing Date multiplied by a fraction, the numerator of which
is the Interest Percentage of the Limited Partner of said Deemed Partnership in
the Partnership plus the Interest Percentage of the General Partner in the
Deemed Partnership and the denominator of which is 100.

                  SECTION 7.1.  Reports.

                  (a) The books of account and records of the Partnership shall
be audited as of the end of each Fiscal Year by the Partnership's independent
public accountants. All reports provided to the Limited Partners pursuant to
this Section 7.1 shall be prepared on an accrual basis. The Partnership's
independent public accountants shall be a nationally recognized independent
certified public accounting firm selected by the General Partner. Until such
time as the Limited Partners become shareholders of Mark Centers Trust, the
Partnership shall deliver to the Limited Partners a copy of any reports and
other correspondence sent by Mark Centers Trust to the Partnership, as a
shareholder of Mark Centers Trust promptly after receipt thereof.

                  (b) Within 15 days after the end of each fiscal quarter, the
General Partner shall prepare and mail to each Person who was a Partner during
such quarter an unaudited report setting forth as of the end of such fiscal
quarter:


704007.16

                             (i)    unless such quarter is the last fiscal
         quarter, a balance sheet of the Partnership;

                            (ii) unless such quarter is the last fiscal quarter,
         an income and expense statement of the Partnership reflecting the cash
         flow of the Partnership for such fiscal quarter (including an estimate
         of the amount of UBTI that is expected to be incurred for such quarter
         and the related Fiscal Year); and

                           (iii) a status report of the Partnership's
         Investments and activities during such fiscal quarter.

                  (c) Within 45 days after the end of each Fiscal Year, the
General Partner shall prepare (or cause to be prepared) and mail to each
Partner, an audited report setting forth as of the end of such Fiscal Year:

                             (i)    a balance sheet of the Partnership,

                            (ii) an income and expense statement of the
         Partnership reflecting the cash flow of the Partnership for such Fiscal
         Year, and

                           (iii) a statement of each Partner's Capital Account.

                  (d) Each Limited Partner other than an Affiliate of the
General Partner agrees that it will not, and it will cause its employees,
representatives and advisors not to, disclose the information in any reports
issued pursuant to this Section 7.1 to any Person without the prior written
consent of the General Partner; provided that any Limited Partner may make such
disclosures as it reasonably believes may be required by law, regulation or rule
of any governmental authority or in conjunction with any litigation proceeding.

                  (e) After the end of each Fiscal Year, the General Partner
shall cause the Partnership's independent certified public accountants to
prepare and transmit, as promptly as possible, and in any event within 45 days
of the close of the Fiscal Year, a federal income tax form K-1 for each Partner,
a copy of the Partnership's return filed for federal income tax purposes and a
report setting forth in sufficient detail such transactions effected by the
Partnership during such Fiscal Year as shall enable each Partner to prepare its
federal income tax return, if any. The General Partner shall mail such materials
to (i) each Partner and (ii) each former Partner (or its successors,

preparing its federal income tax return.

                  SECTION 8.1.  Exculpation and Indemnification.

                  (a) Notwithstanding anything to the contrary in this
Agreement, the General Partner, its members and Affiliates and its and their
directors, officers, shareholders, partners, trustees and employees
(individually, a "Released Party" and collectively, the "Released Parties")
shall not be liable to the Partnership or to the Limited Partners for any
losses, claims, damages or liabilities arising from any act or omission
performed or omitted by such Released Party arising out of or in connection with
this Agreement or the Partnership's business or affairs, except for (i) any such
loss, claim, damage or liability attributable to the negligence or willful
misconduct of such Released Party or a material breach of this Agreement which
such Released Party fails to cure, or fails to cause the General Partner to
cure, within ten (10) Business Days following receipt by the General Partner of
notice of such breach from the Required Partners (a "Breach"), provided that if
such breach is capable of being cured but cannot be cured with diligent efforts
within such period of 10 Business Days and if such Released Party or the General
Partner, as the case may be, has commenced to cure such breach within such
period of 10 Business Days, no Breach of this Agreement shall be deemed to have
occurred unless either (a) such Released Party or the General Partner, as the
case may be, ceases to proceed diligently to cure such breach or (b) such breach
is not cured within fifteen (15) days after the receipt by the General Partner
of such notice of the breach, or (ii) any such loss, claim, damage or liability
attributable to or arising out of or as a result of any Released Party's
position as an officer, director, trustee or controlling stockholder (except in
the case of any such loss, claim, damage or liability attributable to such
person's position as a controlling stockholder arising solely by reason of the
initial funding of the Partnership Investment pursuant to the Contribution
Agreement) of Mark Centers Trust or with respect to actions taken or omitted to
be taken by them in such capacity. The General Partner shall, to the fullest
extent permitted by applicable law, indemnify, defend and hold harmless the
Partnership and the Limited Partners against any losses, claims, damages or
liabilities to which the Partnership or such Limited Partners may become subject
in connection with (i) any

<PAGE>



Breach or (ii) actions or omissions of any Released Party after the Closing Date
relating to their positions as executive officers, trustees, directors or
controlling stockholders (except in the case of any such loss, claim, damage or
liability attributable to such person's position as a controlling stockholder
arising solely by reason of the initial funding of the Partnership Investment
pursuant to the Contribution Agreement) of Mark Centers Trust or actions taken
or omitted to be taken by them in such capacity.

                  (b) The Partnership shall, to the fullest extent permitted by
applicable law, indemnify, defend and hold harmless each Released Party against
any losses, claims, damages or liabilities to which such Released Party may
become subject in connection with any matter arising out of or in connection
with this Agreement or the Partnership's business or affairs, except for any
such loss, claim, damage or liability attributable to the gross negligence,
willful misconduct or Breach of such Released Party or as a result of any
Released Party's position as an officer, trustee, director or controlling
stockholder of Mark Centers Trust or with respect to actions taken by or omitted
to be taken by any Released Party in such capacity. If any Released Party
becomes involved in any capacity in any action, proceeding or investigation in
connection with any matter arising out of or in connection with this Agreement
or the Partnership's business or affairs, the Partnership shall reimburse such
Released Party for its legal and other expenses (including the cost of any
investigation and preparation) as they are incurred in connection therewith,
provided that such Released Party shall promptly repay to the Partnership the
amount of any such reimbursed expenses paid to it if it shall ultimately be
determined that such Released Party was not entitled to be indemnified by the
Partnership in connection with such action, proceeding or investigation. Any
such obligation of the Partnership shall be limited to the assets of the
Partnership and there shall be no personal liability of any of the Limited
Partners for any such obligation of the Partnership.

                  (c) Each Partner covenants for itself and its successors,
assigns, heirs and personal representatives that such Person will, at any time
prior to or after dissolution of the Partnership, on demand, whether before or
after such Person's withdrawal from the Partnership, pay to the Partnership or
the General Partner any amount which the Partnership or the General Partner, as
the case may be, pays in respect of taxes (including withholding taxes) imposed
upon income of or distributions to such Partner.

                                    DURATION AND DISSOLUTION OF THE PARTNERSHIP

                  SECTION 9.1. Duration. The term of the Partnership shall
commence on the Effective Date and, subject to Section 9.2, the term of the
Partnership shall continue until the earlier of (i) December 31, 2005 and (ii)
the date by which no further distributions or deemed distributions will be made
to the Partners pursuant to Sections 6.1(a) or 6.1(e).

                  SECTION 9.2.  Dissolution.  Subject to the Act, the
Partnership shall be dissolved and its affairs shall be wound up
upon the earliest to occur of:

                  (a)  the expiration of the term of the Partnership
provided in Section 9.1;

                  (b)  the written consent of the Partners to dissolve
the Partnership;

                  (c) a decision made by the General Partner to dissolve the
Partnership because it has reasonably determined that changes in any applicable
law or regulation would have a material adverse effect on the continuation of
the Partnership and has delivered to all of the Limited Partners an opinion of
counsel reasonably acceptable (as to the opinion itself and the counsel
rendering such opinion) to the Limited Partners to that effect;

                  (d) the withdrawal, removal or other cessation of the General
Partner as a general partner of the Partnership (within the meaning of the Act)
or the termination of the active engagement of either Ross Dworman or Kenneth F.

Partner shall be the liquidator to wind up the affairs of the Partnership
pursuant to this Agreement. If no general partner remains, the Limited Partners

such liquidation. Subject to the Act (and with respect to any distribution of
assets, Section 6.7), the

liquidator shall dispose of or distribute all Partnership assets to the Partners
within one year following dissolution, except that such one-year period may be
extended with the approval of the Limited Partners.

                  SECTION 9.4.  Distribution Upon Dissolution of the
Partnership.

                  (a) Upon dissolution of the Partnership, the liquidator shall
make a distribution in kind to the Partners. Subject to the Act, after all
liabilities contingent or otherwise of the Partnership (including any
liabilities to Partners and any obligations to Partners under Section 3.4) have
been satisfied or duly provided for (as determined by the liquidator in its
discretion), the remaining assets of the Partnership shall be distributed to the
Partners in proportion to their positive Capital Accounts (after giving effect
to adjustments attributable to all Partnership transactions prior to any such
distribution).

                  (b) The full rights, powers and authority of the liquidator
shall continue so long as appropriate and necessary to complete the process of
winding up the business and affairs of the Partnership.

                  (c) In the discretion of the liquidator a portion of the
distributions that would otherwise be made to the Partners pursuant to this
Section 9.4 may be:

                             (i) distributed to a trust established for the
         benefit of the Partners for the purposes of liquidating Partnership
         assets and collecting amounts owed to the Partnership to the extent
         required for paying any liabilities or obligations of the Partnership
         or of the General Partner arising to of or in connection with the
         Partnership. (Subject to Section 6.7, the assets of any such trust
         shall be distributed to the Partners from time to time, in the
         discretion of the liquidator, in the same proportions as the amount
         distributed to such trust by the Partnership would otherwise have been
         distributed to the Partners pursuant to this Agreement); or

                            (ii) withheld to provide a reserve for Partnership
         liabilities (contingent or otherwise), provided that such withheld
         amounts shall be distributed to the Partners as soon as the liquidator
         determines, in its discretion, that such amounts are no longer
         necessary to be retained.

                  (d) Except as otherwise provided in this Agreement, (i) each
Partner shall look solely to the assets of the Partnership for the return of its
Capital Contributions and (ii) no Limited Partner shall have priority over any
other Limited Partner as to the return of its Capital Contributions. Subject
only to any applicable provisions of the Act, in conjunction with the
dissolution of the Partnership, no Partner shall have any obligation to
contribute to or reimburse the Partnership for any deficit in such Partner's
Capital Account.

                                   TRANSFERABILITY OF GENERAL PARTNER'S INTEREST

                  SECTION 10.1.  Transferability of General Partner's
Interest.

                  (a) Except as otherwise provided herein, the General Partner
may not Transfer all or any portion of its Interest to any Person without the
prior approval of the Required Partners.

                  (b) In connection with any Transfer permitted hereunder, the
General Partner may admit a transferee as a general partner of the Partnership
without further action by any partner or any other Person, and such transferee
shall be deemed admitted to the Partnership as a general partner of the
Partnership immediately prior to the Transfer and shall continue the business of
the Partnership without dissolution.

                  (c) Notwithstanding, the foregoing, the General Partner agrees
that no Transfer contemplated by this Section 10.1 shall be effected if such
Transfer would jeopardize the status of the Partnership as a partnership for
federal income tax purposes.

                  (d) In connection with any Transfer permitted hereunder, all
expenses, including attorneys' fees and expenses, incurred by the Partnership in
connection with such Transfer shall be fully borne by the General Partner or the
General Partner's transferee. In addition, the General Partner or the General
Partner's transferee shall indemnify the Partnership in a manner reasonably
satisfactory to the Limited Partners against any losses, claims, damages,
liabilities or expenses to which the Partnership may become subject arising out
of or based upon any false representation or warranty made by, or breach or
failure to comply with any covenant or agreement of, the General Partner or the
General Partner's transferee in connection with such Transfer.

                  (a) In the event of fraud, gross negligence, willful
misconduct, or an Event of Default by the General Partner, the General Partner

(other than any Limited Partner that is an Affiliate of the General Partner)
representing 66.67% of the aggregate Capital Contributions of all Limited
Partners (other than any Limited Partner that is an Affiliate of the General
Partner).

                  (b) Upon the removal of the General Partner pursuant to
Section 10.2(a), (i) the Partnership shall immediately and automatically be
terminated, and (ii) the Carried Interest shall not be payable to such removed
General Partner.

                  (c) The removal of the General Partner pursuant to Section

for any fraud, gross negligence, willful misconduct, or an Event of Default by
the General Partner.


                  SECTION 10.3. Withdrawal of the General Partner. Except as

Interest (including some or all of its rights or obligations hereunder) may be
made (other than to an Affiliate of the Limited Partner) without the prior
written consent of the General Partner in its absolute discretion. After 18
months from the Closing Date, a Limited Partner may transfer all or a portion of
its Interest upon the prior written consent of the General Partner. If the
General Partner does not consent to such Transfer (unless the General Partner
withholds its consent because of evidence that the proposed transferee has a
reputation of committing acts of moral turpitude), the interest of such Limited
Partner in the Partnership shall be redeemed, the Partnership shall distribute
Shares and any other assets to such Limited Partner in accordance with its
Interest Percentage, and within six months of such distribution the Limited
Partner shall

this Agreement without the written consent of the General Partner.

                  SECTION 11.2. Expenses of Transfer; Indemnification. All
expenses, including attorneys' fees and expenses, incurred by the General
Partner or the Partnership in connection with any Transfer shall be fully borne
by the transferring Limited Partner or such Limited Partner's transferee. In
addition, the transferring Limited Partner or such transferee shall indemnify
the Partnership and the General Partner in a manner reasonably satisfactory to
the General Partner against any losses, claims, damages, liabilities or expenses
to which the Partnership or the General Partner may become subject arising out
of or based upon any false representation or warranty made by, or breach or
failure to comply with any covenant or agreement of, such transferring Limited
Partner or such transferee in connection with such Transfer.

                  SECTION 11.3.  Recognition of Transfer.

                  (a) The Partnership shall not recognize for any purpose any
purported Transfer of all or any portion of a Limited Partner's Interest
(including some or all of its rights or obligations hereunder) and no transferee
of all or any portion of such Interest shall be admitted as a Limited Partner
hereunder unless:

                  (1) the provisions of Sections 11.1, 11.2 and 11.3(b) shall
         have been complied with;

                  (2) the General Partner shall have been furnished with the
         documents effecting such Transfer, in form and substance satisfactory
         to the General Partner, executed and acknowledged by both transferor
         and the transferee;

                  (3) such Transfer shall have been made in accordance with all
         applicable laws and regulations and all necessary governmental consents
         shall have been obtained and requirements satisfied, including the
         Transfer having been made pursuant to an exemption from the Securities
         Act of 1933 and in compliance with the provisions of New York Corporate
         Securities Law or any other applicable state real estate or securities
         laws or regulations, and such Transfer shall not jeopardize the
         availability of the Partnership's exemption from registration in
         connection with the original

704007.16
                                      -38-

         offering and sale of Interests referred to in Section
         12.4(a); and

                  (4) the General Partner shall have received such advice and
         opinions from counsel to the transferor and counsel to the Partnership
         as the General Partner shall reasonably deem appropriate to determine
         that the Transfer complies with the requirements of clause (3) above.

                  (b) Each transferee, as a condition to its admission as a
Limited Partner, shall execute and acknowledge such instruments, in form and
substance satisfactory to the General Partner, as the General Partner deems
necessary or desirable to effectuate such admission and to confirm the agreement
of such Limited Partner to be bound by all the terms and provisions of this
Agreement with respect to any rights and/or obligations represented by the
Interest acquired by such Limited Partner. The admission of any such Limited
Partner shall not require the approval of any Limited Partner.

                  SECTION 11.4. Transfers During a Fiscal Year. If any Transfer
of a Partner's Interest shall occur at any time other than the end of a Fiscal
Year, the distributive shares of the various items of Partnership income, gain,
loss and expense as computed for tax purposes and the distributions of the
Partnership shall be allocated between the transferor and the transferee
consistent with applicable requirements under Code Section 706; provided that no
such allocation shall be effective unless the transferor and the transferee
shall have agreed to reimburse the General Partner for any incremental
accounting fees and other expenses incurred by the General Partner in making
such allocation. Neither the General Partner nor the Partnership shall incur any
liability for making allocations and distributions in accordance with the
provisions of this Section 11.4.

                  SECTION 11.5. Withdrawal of a Limited Partner. Except as
otherwise provided in this Article XI, a Limited Partner may not withdraw from
the Partnership prior to its dissolution.

         this Agreement) or (z) change the method of distribution or allocations
         made under Article VI to any Partner (other than as provided in this

         Contributions representing the percentage of Capital Contributions

         approval of the Partners, amend such provision.

                  SECTION 12.2. Approvals. To the extent permitted by applicable
law, each Limited Partner agrees that the written approval of the Required

of the Required Partners and absent death or disability of either of them, the
ownership of interests in the General Partner shall not be voluntarily
transferred, pledged or otherwise conveyed other than among such individuals or

all of the terms and conditions of the Act. If, nevertheless, it shall be
determined by a court of competent jurisdiction that any provision or wording of
this Agreement shall be invalid or unenforceable under said Act or other
applicable law, such invalidity or unenforceability shall not invalidate the
entire Agreement. In that case, this Agreement shall be construed so as to limit
any term or provision so as to make it enforceable or valid within the
requirements of applicable law, and, in the event such term or provision cannot
be so limited, this Agreement shall be construed to omit such invalid or
unenforceable provisions. If it shall be determined by a court of competent
jurisdiction that any provision relating to the distributions and allocations of
the Partnership or to any fee payable by the Partnership is invalid or
unenforceable, this Agreement shall be construed or interpreted so as (i) to
make it enforceable or valid and (ii) to make the distributions, allocations and
fees as

or any state or other jurisdiction which governs the conduct of its business
from time to time.

hereby constitute and appoint the General Partner as its true and lawful
representative and attorney-in-fact, in its name, place and stead to make,
execute, sign, deliver and file (i) a Certificate of Limited Partnership of the
Partnership, any amendment thereof required because of an amendment to this
Agreement or in order to effectuate any change in the membership of the
Partnership, (ii) any amendments to this Agreement pursuant to Section 12.1, and
(iii) all such other instruments, documents and certificates which may from time
to time be required by the laws of the United States of America, the State of
Delaware or any other state, or any political subdivision or agency thereof, to
effectuate, implement and continue the valid and subsisting existence of the
Partnership or to dissolve the Partnership.

                  The power of attorney granted hereby is coupled with an
interest and shall (a) survive and not be affected by the subsequent death,
incapacity, disability, dissolution, termination or bankruptcy of the Limited
Partner granting the same or the transfer of all or any portion of such Limited

                  SECTION 3.9.  Meetings of Partners.

                  (a) Partnership meetings shall be held at the Partnership's
principal executive office (unless another address is duly noticed by the
General Partner to all of the Partners), and shall be held (i) when called by
the General Partner or, (ii) as respects any matter on which the Limited
Partners may vote or are required to be consulted or to consent, when called by
any Limited Partners representing more than ten percent (10%) of the aggregate
Interest Percentages held by all of the Limited Partners. Notice of a meeting
shall be given in accordance with the provisions of Section 12.15, unless such
notice is waived by all of the Partners. Partners may participate in a meeting
of the Partnership through the use of conference telephones or similar
communication equipment, so long as all Partners participating in the meeting
can hear one another.

                  (b) Any action which may be taken at any meeting of the
Partners may be taken without a meeting if a consent in writing, setting forth
the action so taken, shall be signed by Partners having not less than the
minimum number of votes that would be necessary to authorize or take that action
at a meeting at which all Partners entitled to vote thereon were present and

voted. Any written solicitation for the consent of any Limited Partner to the
taking of any action shall be simultaneously forwarded by the General Partners
to all of the other Limited Partners. Any action taken without a meeting as
provided in this Section 3.9(b) shall be effective as of the date for
effectiveness set forth in the written document evidencing such consent, or, if
no such date is set forth, then on the date upon which the last required
signature of a Partner thereon is obtained. The record date for determining
Partners entitled to give written consent to Partnership action without a
meeting shall be the day on which the first written consent is given. Similarly,
any action which may be taken only after obtaining the consent of the Required
Partners may be taken without a meeting if a consent in writing, setting forth
the action to be so taken, shall be signed by Partners having not less than the
minimum number of votes that would be necessary to authorize or take that action
at a meeting at which all Partners entitled to vote thereon were present and
voted.


                                   ARTICLE IV

                    INVESTMENTS AND INVESTMENT OPPORTUNITIES

                  SECTION 4.1.  Investments Generally.

                  The assets of the Partnership shall consist solely of the
Shares, and any cash from time to time distributed to the Partnership with
respect thereto which may be invested pending distribution to the Partners as
set forth hereunder.

                  SECTION 4.2. Partner Investments. Nothing in any other
provision of this Agreement shall limit the right of the Partners or any of
their Affiliates, and each of them shall be permitted without first having
consulted with any other Partner to engage in or conduct any other business.

                  SECTION 4.3.  Additional Rights of Limited Partner with
Respect to the Investment.

                  (a)  Right of First Preference for Preferred Stock.

                  (i) If, following the Closing Date, Mark Centers Trust engages
in an offering of preferred stock convertible into common shares of beneficial
interest of Mark Centers Trust (the "Offered Stock"), it has agreed, pursuant to
the Contribution Agreement, to use its commercially reasonable efforts to
provide the Limited Partner and the limited partners of the Sister Partnerships

704007.15


<PAGE>



(collectively, with the Limited Partner, the "Sister LPs" and individually, a
"Sister LP") with a right of first preference to purchase shares of Offered
Stock in the first offering or offerings with respect to an aggregate of $75
million (the "Offering") of such Offered Stock which occurs subsequent to the
Closing Date, on terms and conditions which will be identical to the offer and
sale of such Offered Stock to investors other than the Sister LPs.
Notwithstanding the foregoing, up to $10 million of the Offering may be reserved
for Persons other than the Sister LPs. If the Offering is increased to up to $90
million, the excess of the amount of the Offering over $75 million may also be
reserved for Persons other than the Sister LPs, and if the Offering is increased
to above $90 million, the right of first preference to purchase shares of
Offered Stock in favor of the Sister LPs shall equal the sum of (I) $65 million
and (II) the lesser of (A) $10 million and (B) the excess of (i) the amount of
the Offering over (ii) $90 million.

                  (ii) The Partners hereby acknowledge that the terms of the
Offered Stock will be subject to the discretion of Mark Centers Trust.
Notwithstanding the foregoing, the General Partner, as authorized in the
Contribution Agreement, hereby grants to the Limited Partner, and agrees to use
its best efforts to cause Mark Centers Trust to offer to the Limited Partner,
the right to acquire at least its pro rata share of the Offered Stock. The
General Partner hereby agrees that the Sister LPs shall have the right to
acquire the Offered Stock, if any, in accordance with the following procedures:

                  1. If the Limited Partner and the other Sister LPs elect to
                  acquire all or any portion of the Offered Stock, then the
                  Limited Partner may acquire up to its pro rata share of the
                  Offered Stock. Such pro rata share shall be determined by
                  multiplying the number of shares of Offered Stock times a
                  fraction, the numerator of which is the number of Shares
                  acquired by the Partnership and the denominator of which is
                  the aggregate number of Shares and common shares of beneficial
                  interest of Mark Centers Trust acquired by the Partnership and
                  the Sister Partnerships.

                  2. If any Sister LP elects not to purchase all or any portion
                  of its pro rata share of the Offered Stock, the General
                  Partner will use its best efforts to cause Mark Centers Trust
                  to offer to the Limited Partner and the other Sister LPs the
                  right to purchase some or all of the remaining Offered Stock.
                  The Limited Partner and those other Sister LPs desiring to
                  purchase additional

704007.15


<PAGE>



                  shares of Offered Stock may purchase up to their pro rata
                  share as determined above of the remaining Offered Stock until
                  such remaining Offered Stock is either purchased or the
                  Limited Partner and the other Sister LPs no longer desire to
                  purchase any additional Offered Stock.

                  (b) Registration Rights. Reference is made to the form of
Registration Rights and Lock-Up Agreement attached as Exhibit E to the
Contribution Agreement (the "Registration Rights Agreement"). To the extent the
final Registration Rights Agreement entered into on the Closing Date does not
provide that the rights of the Partnership thereunder are automatically
assignable to transferees of the Shares, the General Partner, on behalf of the
Partnership, hereby agrees to assign such rights to the Limited Partners upon
any distribution of the Shares from the Partnership and the General Partner will
cause the Partnership to execute and deliver any and all documents necessary to
effect such assignment.

                  (c) Tag-Along Rights. (i) If the General Partner or any
Affiliate of the General Partner (collectively with the General Partner, a "GP
Affiliate") desires to sell or otherwise dispose of (other than a pledge in
connection with a borrowing) any common shares of beneficial interest of Mark
Centers Trust, options to purchase common shares of beneficial interest of Mark
Centers Trust (not including the exercise of employee stock options granted to
such GP Affiliate who is an officer of Mark Centers Trust), operating
partnership units of Mark Centers Limited Partnership or other securities
convertible into or exchangeable for common shares of beneficial interest of
Mark Centers Trust (collectively, "MCT Securities") held by it to any other
Person other than a GP Affiliate (a "Third Party Sale"), the GP Affiliate shall,
at least thirty (30) Business Days prior to the proposed closing date of such
Third Party Sale, give written notice to the Limited Partner describing such
Third Party Sale in reasonable detail including the price offered and all
material terms and conditions of the Third Party Sale.

                  (ii) The Limited Partner shall have the right and the option,
by written notice given to the selling GP Affiliate within fifteen (15) Business
Days prior to the closing of such Third Party Sale, to sell in such Third Party
Sale the same percentage of the total number of Shares held by the Partnership
(or direct the Partnership to sell such number of Shares) as the number of MCT
Securities to be sold by the selling GP Affiliate or Affiliates represents to
all MCT Securities held by such GP Affiliate or Affiliates.

704007.15


<PAGE>



                  (iii) In the event a Third Party Sale is proposed, the right
granted under this Section 4.3(c) shall be exercisable by the Partnership at the
written request of the Limited Partner.

                  (d) Pre-emptive Rights. In the event that any GP Affiliate
receives pre-emptive rights to acquire MCT Securities (the "Pre-emptive
Rights"), such GP Affiliate shall grant to the Limited Partner and/or use its
best efforts to cause Mark Centers Trust (or other giver of Pre-emptive Rights)
to grant to the Limited Partner and the other Sister LPs Pre-emptive Rights to
acquire, on terms no less favorable than those offered to the GP Affiliates, the
same aggregate number of MCT Securities as are subject to the Pre-emptive Rights
offered to such GP Affiliates. Of such Pre-emptive Rights to be given to the
Sister LPs, the Limited Partner shall be entitled to acquire its pro rata share
of such MCT Securities. Such pro rata share shall be determined in the same
manner as is set forth in Section 4.3(a)(ii).

                  (e) Pass-through of Right to Purchase. In the event that Mark
Centers Trust commences a rights offering for any securities or other similar
offering of rights or securities to its shareholders, the Limited Partner may
exercise the rights granted to shareholders of Mark Centers Trust, as if it were
a shareholder with respect to the Shares not otherwise previously distributed to
it pursuant to this Agreement; provided the cost of exercising such rights shall
be paid directly by the Limited Partner.

                  (f) Voting Proxy. Notwithstanding anything else contained in
this Agreement, the General Partner hereby constitutes and appoints the Limited
Partner its true and lawful attorney, agent and proxy to exercise all voting
rights of shareholders of Mark Centers Trust with respect to the number of
Shares owned by the Partnership which would otherwise be distributable to the
Limited Partner if the Partnership were liquidated.

                  (g) Any purchase of securities pursuant to Sections 4.3(a),
(d) and (e) hereof (i) which are required to be purchased in the name of the
Partnership, shall be purchased by the Partnership (upon a contribution of cash
by the Limited Partner therefor) and shall immediately be distributed by the
Partnership to the Limited Partner (ii) shall not be deemed property of the
Partnership and (iii) shall not be subject to the provisions of this Agreement,
including without limitation, the provisions relating to the Preferred Return,
Carried Interest or distributions.


704007.15


<PAGE>



                  (h) The provisions of Sections 4.3(c) through (f) hereof shall
terminate upon the earlier to occur of (i) the termination or dissolution of the
Partnership and (ii) thirty (30) months after the Closing Date (collectively,
the "Expiration Date"). The provisions of Section 4.3(a) shall survive the
termination or dissolution of the Partnership only if an offering of Offered
Securities has not occurred prior to the Expiration Date and the General Partner
will do whatever is necessary to confirm the continuation of such rights to the
Limited Partner. The provisions of Section 4.3(b) shall survive the termination
or dissolution of the Partnership.


                                    ARTICLE V

                              CAPITAL CONTRIBUTIONS

                  SECTION 5.1.  Capital Contributions.

                  (a) Each Partner hereby agrees to make Capital Contributions
to the Partnership in the amount set forth on Schedule B on or before five
business days prior to the Closing Date. The General Partner shall send a
written notice to each Limited Partner at least five business days before the
date on which the Capital Contribution is to be made. All Capital Contributions
shall be paid to the Partnership in immediately available funds in United States
dollars by 2:00 p.m. (New York time) on the date specified by the General
Partner. The General Partner may pursue any remedies available to the
Partnership, in law or at equity, against any Partner who fails to make a
Capital Contribution as required pursuant to this Agreement, including the
commencement of an action seeking specific performance and/or damages, and after
the closing of the transactions contemplated by the Contribution Agreement, if
the Limited Partner has failed to make all or a portion of its Capital
Contribution, the General Partner's rights hereunder to pursue such remedies may
be exercised by Mark Centers Trust directly. Notwithstanding the foregoing, the
Partners shall not be obligated to make Capital Contributions as described
herein if (i) there is an amendment to the Contribution Agreement that could
reasonably be expected to be materially adverse to the Investment, the Limited
Partner or the Partnership, (ii) the General Partner (or an Affiliate of the
General Partner) waives a condition to closing under the Contribution Agreement
which could reasonably be expected to be materially adverse to the Investment,
the Limited Partner or the Partnership, or (iii) there is any increase over $25
million in the aggregate amount of Offered Stock offered to, or reserved for,
any Person other than the Limited Partner and the Sister

704007.15


<PAGE>



LPs. For purposes hereof, any change to (i) the purchase price per Share, (ii)
the aggregate amount to be invested by the Partnership and all of the Sister
Partnerships in excess of $120 million, (iii) the aggregate number of and
percentage of the outstanding common shares of beneficial interest of Mark
Centers Trust represented by the Shares to be purchased, as compared with such
number and percentage assuming a purchase by the Partnership and the Sister
Partnerships of 16 million common shares of beneficial interest of Mark Centers
Trust at $7.50 per share, or (iv) the right of first preference to purchase
Offered Stock, shall be deemed to be materially adverse to the Investment, the
Limited Partner and the Partnership.

                  (b) If the closing under the Contribution Agreement does not
occur for any reason by the earlier of December 31, 1998 and the termination of
the Contribution Agreement, the General Partner shall promptly, and in no event
later than two (2) Business Days after the earlier of such date and the
termination of the Contribution Agreement, pay to the Limited Partner an amount
equal to the Limited Partner's Capital Contribution plus all interest earned
thereon in immediately available funds to an account designated by the Limited
Partner, and the Limited Partner shall be released from and have no further
obligations hereunder.

                  SECTION 5.2. Temporary Investment of Funds. The General
Partner shall invest all cash held by the Partnership in money market
instruments which instruments shall be (i) debt instruments issued or guaranteed
by the United States or its agencies or instrumentalities maturing within six
months or less from the date of acquisition, (ii) commercial paper rated P-1 or
A-1 on the date of acquisition and maturing within six months or less from the
date of acquisition, (iii) overnight time deposits or other interest-bearing
deposits (whether or not insured) in national or state banks (a) having capital
and surplus of at least $1,000,000,000 and having a long-term senior debt rating
by Standard & Poor's Corporation of "A" or better (or an equivalent rating
issued by Moody's Investors Service, Inc.) or (b) otherwise approved by the
Required Partners, (iv) money market mutual funds with assets of at least
$750,000,000 and investments comprised of debt with a credit rating of A1 or P1
or a substantially similar rating and (v) similar quality short-term
investments. Notwithstanding the foregoing, it is not expected that the
Partnership will retain any material cash balances. Any interest earned on
investments pursuant to this Section 5.2 shall be payable to the Partners pro
rata in accordance with their Interest Percentage in the event the Closing does
not occur or in the event the Closing does occur, shall be added to the Capital

704007.15


<PAGE>



Contributions made hereunder, pro rata in accordance with the Partners' Interest
Percentage and shall be applied first to pay Partnership Expenses and second to
purchase Shares.


                                   ARTICLE VI

                 DISTRIBUTIONS, CAPITAL ACCOUNTS AND ALLOCATIONS

                  SECTION 6.1.  Distributions.

                  (a) Prior to the dissolution of the Partnership, the General
Partner shall cause the Partnership, to the extent of Distributable Proceeds, to
make distributions in cash, as soon as practicable (and in all events within two
(2) Business Days) after receipt of such proceeds, to the Partners as follows:

                             (i) first, to the Limited Partners in payment of
         the preferred return described in Section 6.2 pro rata in accordance
         with their Interest Percentages;

                            (ii) second, to the Partners, pro rata in accordance
         with their respective amounts of Unreturned Capital until each such
         Partner has received distributions pursuant to this Section 6.1(a)(ii)
         in an aggregate amount equal to its Capital Contribution as of the date
         of such distribution; and

                           (iii) third, (A) 80% to the Limited Partners, pro
         rata in accordance with their respective Interest Percentages, and (B)
         20% to the General Partner.

                  (b) The General Partner shall determine and distribute
Distributable Proceeds promptly (and in all events within two (2) Business Days)
after the Partnership receives cash proceeds.

                  (c) Notwithstanding anything in this Agreement to the
contrary, the Partnership shall make no distributions except to the extent
permitted under the Act.

                  (d)  Intentionally Deleted.

                  (e) (i) Each Limited Partner shall have the right to cause the
         Partnership to distribute to it a number of Shares as determined in
         accordance with the following formula, at or about the times indicated
         below:

                       (18th) month after the Closing Date, the product of (i)
                       one-third of the number of Shares held by the Partnership
                       and (ii) the Limited Partner's Interest
                       Percentage;

                             (B) At any time commencing after the twenty-fourth
                       (24th) month after the Closing Date, the greater of the
                       product of (i) (a) one-half of the number of Shares then
                       held by the Partnership and (b) the Limited Partner's
                       Interest Percentage and (ii)(a) two-thirds of the number
                       of Shares originally acquired by the Partnership less any
                       Shares distributed to the Limited Partner pursuant to
                       Section 6.1(e)(i)(A) and (b) the Limited Partner's
                       Interest Percentage;

                             (C) At any time commencing after the thirtieth
                       (30th) month after the Closing Date, the product of (i)
                       the number of Shares then held by the Partnership and
                       (ii) the Limited Partner's Interest
                       Percentage.

                       (ii) If any of the following shall occur: (a) both Ross
         Dworman and Kenneth Bernstein are not executive officers of Mark
         Centers Trust and spending a substantial portion of their time on the
         management of Mark Centers Trust, (b) a tender offer is initiated for
         the shares of Mark Centers Trust, (c) the closing price per share of
         Mark Centers Trust common stock as officially reported on the principal
         national securities exchange on which the shares are then listed or
         admitted for trading is less than $7.50 per share for more than twenty
         consecutive Business Days at any time after the last day of the

         beneficial interest of Mark Centers Trust have been suspended from
         trading or have been delisted, (d) either Ross Dworman or Kenneth
         Bernstein are the subject of a governmental investigation required to
         be disclosed pursuant to Items 401(f)(2) through (6) of Regulation S-K
         promulgated under the Securities Act of 1933, as amended (or any

         uncured Event of Default shall have occurred, (g) the funds from
         operations (as described on Schedule E) per common share of beneficial
         interest of

704007.15


<PAGE>



         Mark Centers Trust for the twelve-month period ending on March 31, 2000
         as reported in the audited financial statements of Mark Centers Trust
         is less than $0.72, (h) the General Partner is removed pursuant to
         Section 10.2, (i) either Ross Dworman or Kenneth Bernstein is no longer
         a member of the board of trustees of Mark Centers Trust, or (j) either
         Ross Dworman or Kenneth Bernstein has, as a result of a voluntary
         decision, ceased to be an executive officer of Mark Centers Trust who
         spends a substantial portion of his time on the management of Mark
         Centers Trust,

         then each Limited Partner will have the right to cause the Partnership
         to distribute to it, upon request, the number of Shares equal to (a)
         the product of (A) the number of Shares then held by the Partnership
         and (B) such Partner's Interest Percentage.

                           (iii) At the time a distribution is made pursuant to
         Section 6.1(e)(i) or (ii) above, Section 6.7 shall apply and the
         Interest Percentage of the Partners shall be recalculated to reflect
         said distribution.

                            (iv) The General Partner's interest set forth in
         Section 6.1(a)(iii) (the "Carried Interest") will remain in effect with
         respect to distributed Shares until sixty months after the Closing Date
         (which period shall end at such earlier time as may be designated by a
         Limited Partner, but in no event earlier than thirty-six months after
         the Closing Date) unless Shares distributed are actually sold
         (including as Shares actually sold, any such Shares distributed to the
         partners or members of the Limited Partners) by the Limited Partners
         prior to such date. For any distributed shares sold prior to such date,
         the Carried Interest will be calculated at the time of sale with
         respect to the Shares sold based upon the sales price received by the
         Limited Partner for such Shares, net of any broker fees and commissions
         and other expenses and costs of sale, and paid from the Limited Partner
         to the General Partner either in cash or shares, at the option of the
         Limited Partner, in the manner set forth below. Upon sixty months after
         the Closing Date (or such earlier date as may be determined by a
         Limited Partner in accordance with this paragraph) the Carried Interest
         shall be calculated based on the Fair Market Value (except that if the
         Shares are treated as having been sold because the second parenthetical
         in the first sentence of this paragraph applies, the last sentence of
         the definition of Fair Market Value shall not be applied) and paid in
         full, in cash or in shares (at the option of the Limited Partner),

704007.15


<PAGE>



         for all remaining Shares held by the Partnership, the Limited Partners
         and the General Partner. If Shares are distributed pursuant to this
         Section 6.1(e), for purposes of calculating the Carried Interest, (i)
         dividends received on the Shares after the Shares have been distributed
         shall be taken into account and (ii) the value of the Shares at the
         time the Carried Interest is determined (rather than at the time the
         Shares were distributed) shall be applied. At the time the Limited
         Partner determines to sell Shares, the Limited Partner will consider,
         but is not obligated to comply with, a request from the General Partner
         to pay the Carried Interest to the General Partner in Shares in lieu of
         cash.

                             (v) In order to avoid any duplication of fees, at
         the time either (i) the Partnership sells any of its Shares or (ii)
         following a distribution, a Limited Partner sells any of its Shares (in
         either case, a "Triggering Event"), the Carried Interest will be
         reduced to reflect (A) the aggregate "value" on the date of the
         Triggering Event of the options for common shares of beneficial
         interest of Mark Centers Trust held by and/or previously exercised by
         Ross Dworman and Ken Bernstein and (B) any extraordinary compensation
         that has been paid by Mark Centers Trust to Ross Dworman and Ken
         Bernstein (i.e., bonus compensation in excess of amounts customarily
         paid to executive officers of public real estate investment trusts, as
         reasonably determined by the Limited Partner) and the net present
         value, calculated using a discount rate equal to Treasury Securities of
         similar maturity, of amounts payable by Mark Centers Trust to Ross
         Dworman and Kenneth Bernstein as a result of a change in control (as
         defined in any agreement between Mark Centers Trust and either Ross
         Dworman or Kenneth Bernstein) of Mark Centers Trust (the "Excess
         Compensation"). The Carried Interest for the Partnership will be
         reduced by an amount equal to (a) the "value" of all vested options for
         common shares of beneficial interest of Mark Centers Trust held by
         and/or previously exercised by Ross Dworman and Ken Bernstein and the
         Excess Compensation multiplied by (b) a fraction, the numerator of
         which is the number of Shares sold by the Partnership or the Limited
         Partner and the denominator of which is all of the issued and
         outstanding common shares of beneficial interest of Mark Centers Trust
         and operating units of Mark Centers Limited Partnership, on a fully
         diluted basis. For purposes of this calculation, the "value" of the
         options shall be determined using the Black-Scholes method.

                  SECTION 6.2. Preferred Return. No later and no less frequently
than the thirtieth (30th) day following the close of each fiscal quarter, the
General Partner shall determine, based on a statement of operations and cash
flow for the Partnership, which need not be audited, and distribute to the
Limited Partners to the extent of Distributable Proceeds, pro rata in accordance
with their respective amounts of Unreturned Capital, an amount, in the
aggregate, equal to eight percent (8%) per annum of the average monthly balance
of such Partners' aggregate Unreturned Capital (the "Preferred Return")since the
last distribution of Distributable Proceeds. To the extent the Partnership is
unable to make a Preferred Return payment pursuant to this Section 6.2 in any
quarter, the unpaid amount of the Preferred Return will be compounded
semiannually at a rate of 8% per annum and paid in future quarters. No amounts
shall be distributed to Partners pursuant to Section 6.1 (other than Section
6.1(a)(i))or Section 9.4 if any Preferred Return amount required to be paid
under this Section 6.2 is accrued but unpaid. Amounts paid pursuant to this
Section 6.2 are intended to constitute payments of a preferred return for
capital within the meaning of Treasury Regulations ss. 1.514(c)-2(d)(2) and not
guaranteed payments within the meaning of Section 707(c) of the Code.

                  SECTION 6.3.  Capital Accounts.  (a)  There shall be
established for each Partner on the books and records of the
Partnership an account (a "Capital Account"), which shall
initially be zero and which shall be adjusted as follows:

                             (i) The amount of cash contributed to the
         Partnership by each Partner shall be credited to the Capital Account of
         such Partner.

                            (ii) The amount of cash (or the fair market value of
         other property as determined by the General Partner pursuant to this
         Article VI, net of any liabilities assumed or taken subject to by the
         Partners) distributed by the Partnership to each Partner shall be
         debited against the Capital Account of such Partner.

                           (iii) The Net Income and Net Loss of the Partnership
         (and the items entering into the determination thereof) allocated to
         each Partner pursuant to this Article VI shall be credited to and
         debited against, respectively, the Capital Account of such Partner.

                       (b)  If all or any portion of an Interest is
transferred in accordance with this Agreement, the transferee

704007.15


<PAGE>



shall succeed to the Capital Account of the transferor to the extent it relates
to the transferred Interest or portion thereof.

                       (c)  The provisions of this Agreement relating to
the maintenance of Capital Accounts are intended to comply with applicable
Regulations under Code Section 704 and to provide for allocations which have
"substantial economic effect" within the meaning of those Regulations and shall
be interpreted and applied in a manner consistent with this intention.

                  SECTION 6.4.  Allocations of Net Income and Net Loss.

                  (a) Net Income. Except as otherwise provided in this Article
VI, Net Income for each Fiscal Year shall be allocated in the following order:

                             (i) first, if any Net Loss has been previously
         allocated to the Partners, reversing the prior allocations of Net Loss
         on a most recent in time basis until the cumulative amount allocated
         pursuant to this Section 6.4(a)(i) equals the cumulative amount of Net
         Loss previously so allocated; and

                            (ii) second, to the Partners in an amount equal to
         the distributions made to each Partner (or which would be made to each
         Partner, if the Partnership distributed cash in an amount equal to such
         Net Income) pursuant to Section 6.1(a).

                  (b) Net Loss. Except as otherwise provided in this Article VI,
Net Loss for each Fiscal Year shall be allocated to the General Partner and the
Limited Partners in proportion to their Interest Percentages.

                  (c) Miscellaneous. Any Net Income or Net Loss allocated to the
Limited Partners shall be allocated among the Limited Partners pro rata in
accordance with their Interest Percentages.

                  SECTION 6.5.  Other Allocations.

                  (a)  Other Allocation Rules.

                             (i) To the extent required by Code Section 704 and
         the Regulations thereunder, income, gain, loss, deduction and credit
         with respect to any property shall, solely for tax purposes (and not
         for purposes of maintaining the Capital Accounts hereunder), be
         allocated among the

704007.15


<PAGE>



         Partners so as to take account of any variation between the adjusted
         basis of such property for federal income tax purposes and its 704(c)
         Value. Any elections or other decisions relating to such allocation
         shall be made by the General Partner with the consent of the Required
         Partners.

                  "704(c) Value" means, with respect to any Partnership asset,
the adjusted basis for federal income tax purposes of such asset, adjusted as of
the following times to equal its gross fair market value (as determined by the
General Partner in its discretion): (a) the acquisition of an additional
Interest by any new or existing Partner in exchange for more than a de minimis
(as that term is used in Regulation Section 1.704-1(b)(2)(iv)(f)) Capital
Contribution; (b) the distribution by the Partnership to a Partner of more than
a de minimis amount of Partnership property or money if the General Partner
determines in its discretion that such adjustment is necessary or appropriate to
reflect the economic interests of the Partners in the Partnership; and (c) the
liquidation of the Partnership for federal income tax purposes within the
meaning of Regulation Section 1.704(b)(2)(ii).

                  SECTION 6.6. Tax Allocations. All items of income, gain, loss,
deduction or credit of the Partnership shall be allocated among the Partners for
federal income tax purposes in a manner consistent with the allocation of the
corresponding items to the Partners under the other provisions of this Article
VI.

                  SECTION 6.7. Distributions in Kind. The General Partner may
distribute any property constituting all or any portion of an Investment in
kind. Any property so distributed shall be deemed for purposes of determining
Net Income or Net Loss under this Article VI to have been sold by the
Partnership for an amount equal to its Fair Market Value (calculated in United
States dollars). Except as provided in Section 6.1(e), in any distribution of
property in kind, the General Partner shall not, without the consent of all the
Limited Partners, discriminate among Partners and shall endeavor to (i)
distribute to each applicable Partner a proportional interest in any particular
property in accordance with this Article VI and (ii) if cash and property in
kind are to be distributed simultaneously in respect of any Investment,
distribute cash and property in kind in the same proportion to each applicable
Partner.

                  Notwithstanding the foregoing, if any Limited Partner notifies
the General Partner that such Limited Partner is prohibited by applicable law or
regulation from holding directly the property to be distributed in kind, the
General Partner

704007.15


<PAGE>



shall, in lieu of making such distribution in kind to such Limited Partner and
to the extent permitted by applicable law, use commercially reasonable efforts
to sell such property on such Limited Partner's behalf, on terms acceptable to
such Limited Partner and, upon such sale, the General Partner shall promptly
distribute to such Limited Partner the net proceeds of such sale.

                  SECTION 6.8. Setoff and Withholding of Certain Amounts.
Notwithstanding anything else contained in this Agreement, the General Partner
may in its discretion set off against, or withhold from, any distribution to any
Partner pursuant to this Agreement, the following amounts:

                       (a) any amounts due from such Partner to the Partnership
         or the General Partner pursuant to this Agreement to the extent not
         otherwise paid,

                       (b) any amounts required to pay or reimburse (x) the
         Partnership for the payment of any withholding or other taxes properly
         attributable to such Partner or (y) the General Partner for any
         advances made by the General Partner for such purpose.

                  Any amounts so set off or withheld pursuant to this Section
6.8 shall be applied by the General Partner to discharge the obligation in
respect of which such amounts were withheld. All amounts set off or withheld
either pursuant to this Section 6.8 or pursuant to the Code or any provision of
any state or local tax law attributable to any Partner shall be treated as
amounts distributed to such Partner for all purposes under this Agreement.

                  SECTION 6.9. Withdrawal and Return of Capital. Except as
specifically provided in this Agreement, a Partner shall not have any right to
demand the return of any Capital Contribution or to withdraw any portion of
Partnership capital. If the Distributable Proceeds remaining upon dissolution of
the Partnership after the payment or discharge of Partnership Expenses are
insufficient to return any Partner's Unreturned Capital, the Partner shall have
no recourse against any of the Partners or against the Partnership.

                                   ARTICLE VII

                           REPORTS TO LIMITED PARTNERS

                  SECTION 7.1.  Reports.

                  (a) The books of account and records of the Partnership shall
be audited as of the end of each Fiscal Year by the Partnership's independent
public accountants. All reports provided to the Limited Partners pursuant to
this Section 7.1 shall be prepared on an accrual basis. The Partnership's
independent public accountants shall be a nationally recognized independent
certified public accounting firm selected by the General Partner. Until such
time as the Limited Partner becomes a shareholder of Mark Centers Trust, the
Partnership shall deliver to the Limited Partner a copy of any reports and other
correspondence sent by Mark Centers Trust to the Partnership, as a shareholder
of Mark Centers Trust promptly after receipt thereof.

                  (b) Within 15 days after the end of each fiscal quarter, the
General Partner shall prepare and mail to each Person who was a Partner during
such quarter an unaudited report setting forth as of the end of such fiscal
quarter:

                             (i)    unless such quarter is the last fiscal
         quarter, a balance sheet of the Partnership;

                            (ii) unless such quarter is the last fiscal quarter,
         an income and expense statement of the Partnership reflecting the cash
         flow of the Partnership for such fiscal quarter (including an estimate
         of the amount of UBTI that is expected to be incurred for such quarter
         and the related Fiscal Year); and

                           (iii) a status report of the Partnership's
         Investments and activities during such fiscal quarter.

                  (c) Within 45 days after the end of each Fiscal Year, the
General Partner shall prepare (or cause to be prepared) and mail to each
Partner, an audited report setting forth as of the end of such Fiscal Year:

                             (i)    a balance sheet of the Partnership,

                            (ii) an income and expense statement of the
         Partnership reflecting the cash flow of the Partnership for such Fiscal
         Year, and

704007.15


<PAGE>



                           (iii) a statement of each Partner's Capital Account.

                  (d) Each Limited Partner other than an Affiliate of the
General Partner agrees that it will not, and it will cause its employees,
representatives and advisors not to, disclose the information in any reports
issued pursuant to this Section 7.1 to any Person without the prior written
consent of the General Partner; provided that any Limited Partner may make such
disclosures as it reasonably believes may be required by law, regulation or rule
of any governmental authority or in conjunction with any litigation proceeding.

                  (e) After the end of each Fiscal Year, the General Partner
shall cause the Partnership's independent certified public accountants to
prepare and transmit, as promptly as possible, and in any event within 45 days
of the close of the Fiscal Year, a federal income tax form K-1 for each Partner,
a copy of the Partnership's return filed for federal income tax purposes and a
report setting forth in sufficient detail such transactions effected by the
Partnership during such Fiscal Year as shall enable each Partner to prepare its
federal income tax return, if any. The General Partner shall mail such materials
to (i) each Partner and (ii) each former Partner (or its successors, assigns,
heirs or personal representatives) who may require such information in preparing
its federal income tax return.


                                  ARTICLE VIII

                         EXCULPATION AND INDEMNIFICATION

                  SECTION 8.1.  Exculpation and Indemnification.

                  (a) Notwithstanding anything to the contrary in this
Agreement, the General Partner, its members and Affiliates and its and their
directors, officers, shareholders, partners, trustees and employees
(individually, a "Released Party" and collectively, the "Released Parties")
shall not be liable to the Partnership or to the Limited Partners for any
losses, claims, damages or liabilities arising from any act or omission
performed or omitted by a Released Party arising out of or in connection with
this Agreement or the Partnership's business or affairs, except for (i) any such
loss, claim, damage or liability attributable to the negligence or willful
misconduct of a Released Party or a material breach of this Agreement which a
Released Party fails to cure, or fails to cause the General Partner to cure,
within ten (10) Business Days following receipt

704007.15


<PAGE>



by the General Partner of notice of such breach from the Required Partners (a
"Breach"), provided that if such breach is capable of being cured but cannot be
cured with diligent efforts within such period of 10 Business Days and if such
Released Party or the General Partner, as the case may be, has commenced to cure
such breach within such period of 10 Business Days, no Breach of this Agreement
shall be deemed to have occurred unless either (a) such Released Party or the
General Partner, as the case may be, ceases to proceed diligently to cure such
breach or (b) such breach is not cured within fifteen (15) days after the
receipt by the General Partner of such notice of the breach, or (ii) any such
loss, claim, damage or liability attributable to or arising out of or as a
result of any Released Party's position as an officer or director or controlling
stockholder (except in the case of any such loss, claim, damage or liability
attributable to such person's position as a controlling stockholder arising in
connection with the initial funding of the Partnership Investment pursuant to
the Contribution Agreement) of Mark Centers Trust or with respect to actions
taken or omitted to be taken by them in such capacity. The General Partner
shall, to the fullest extent permitted by applicable law, indemnify, defend and
hold harmless the Partnership and the Limited Partners against any losses,
claims, damages or liabilities to which the Partnership or such Limited Partners
may become subject in connection with (i) any Breach or (ii) actions or
omissions of any Released Party after the Closing Date relating to his positions
as an executive officer or director or controlling stockholder (except in the
case of any such loss, claim, damage or liability attributable to such person's
position as a controlling stockholder arising in connection with the initial
funding of the Partnership Investment pursuant to the Contribution Agreement) of
Mark Centers Trust or actions taken or omitted to be taken by him in such
capacity.

                  (b) The Partnership shall, to the fullest extent permitted by
applicable law, indemnify, defend and hold harmless each Released Party against
any losses, claims, damages or liabilities to which such Released Party may
become subject in connection with any matter arising out of or in connection
with this Agreement or the Partnership's business or affairs, except for any
such loss, claim, damage or liability attributable to the gross negligence,
willful misconduct or Breach of a Released Party or as a result of any Released
Party's position as an officer or director or controlling stockholder of Mark
Centers Trust or with respect to actions taken by or omitted to be taken by any
Released Party in such capacity. If any Released Party becomes involved in any
capacity in any action, proceeding or investigation in connection with any
matter arising out of or in connection with this Agreement or the Partnership's
business or

704007.15


<PAGE>



affairs, the Partnership shall reimburse such Released Party for its legal and
other expenses (including the cost of any investigation and preparation) as they
are incurred in connection therewith, provided that such Released Party shall
promptly repay to the Partnership the amount of any such reimbursed expenses
paid to it if it shall ultimately be determined that such Released Party was not
entitled to be indemnified by the Partnership in connection with such action,
proceeding or investigation. Any such obligation of the Partnership shall be
limited to the assets of the Partnership and there shall be no personal
liability of any of the Limited Partners for any such obligation of the
Partnership.

                  (c) Each Partner covenants for itself and its successors,
assigns, heirs and personal representatives that such Person will, at any time
prior to or after dissolution of the Partnership, on demand, whether before or
after such Person's withdrawal from the Partnership, pay to the Partnership or
the General Partner any amount which the Partnership or the General Partner, as
the case may be, pays in respect of taxes (including withholding taxes) imposed
upon income of or distributions to such Partner.



                                   ARTICLE IX

                   DURATION AND DISSOLUTION OF THE PARTNERSHIP

                  SECTION 9.1.  Duration.  The term of the Partnership
shall commence on the Effective Date and, subject to Section 9.2,
the term of the Partnership shall continue until December 31,
2005.

                  SECTION 9.2.  Dissolution.  Subject to the Act, the
Partnership shall be dissolved and its affairs shall be wound up
upon the earliest to occur of:

                  (a)  the expiration of the term of the Partnership
provided in Section 9.1;

                  (b)  the written consent of the Partners to dissolve
the Partnership;

                  (c) a decision made by the General Partner to dissolve the
Partnership because it has reasonably determined that changes in any applicable
law or regulation would have a material adverse effect on the continuation of
the Partnership and has delivered

704007.15


<PAGE>



to the Required Partners an opinion of counsel reasonably acceptable (as to the
opinion itself and the counsel rendering such opinion) to the Required Partners
to that effect;

                  (d) the withdrawal, removal or other cessation of the General
Partner as a general partner of the Partnership (within the meaning of the Act)
or the termination of the active engagement of either Ross Dworman or Kenneth F.
Bernstein from the Partnership; and

                  (e) any of the events set forth in Section 6.1(e)(ii) shall
have occurred or for any other reason the Partnership no longer holds any
Shares.

                  SECTION 9.3. Winding Up of Partnership. Upon dissolution, the
Partnership's business shall be wound up in an orderly manner. The General
Partner shall be the liquidator to wind up the affairs of the Partnership
pursuant to this Agreement. If no general partner remains, the Limited Partners
may approve one or more liquidators to act as the liquidator in carrying out
such liquidation. Subject to the Act (and with respect to any distribution of
assets, Section 6.7), the liquidator shall dispose of or distribute all
Partnership assets to the Partners within one year following dissolution, except
that such one-year period may be extended with the approval of the Limited
Partners.

                  SECTION 9.4.  Distribution Upon Dissolution of the
Partnership.

                  (a) Upon dissolution of the Partnership, the liquidator shall
make a distribution in kind to the Partners. In performing its duties, the
liquidator is authorized to sell, distribute, exchange or otherwise dispose of
the assets of the Partnership in any manner that the liquidator shall determine
to be in the best interest of the Partners. Subject to the Act, after all
liabilities contingent or otherwise of the Partnership (including any
liabilities to Partners and any obligations to Partners under Section 3.4) have
been satisfied or duly provided for (as determined by the liquidator in its
discretion), the remaining assets of the Partnership shall be distributed to the
partners in proportion to their positive Capital Accounts (after giving effect
to adjustments attributable to all Partnership transactions prior to any such
distribution including the sale of any property deemed to occur under Section
6.7).

                  (b) The full rights, powers and authority of the liquidator
shall continue so long as appropriate and necessary to

704007.15


<PAGE>



complete the process of winding up the business and affairs of
the Partnership.

                  (c) In the discretion of the liquidator a portion of the
distributions that would otherwise be made to the Partners pursuant to this
Section 9.4 may be:

                             (i) distributed to a trust established for the
         benefit of the Partners for the purposes of liquidating Partnership
         assets, collecting amounts owed to the Partnership, and paying any
         liabilities or obligations of the Partnership or of the General Partner
         arising to of or in connection with the Partnership. (Subject to
         Section 6.7, the assets of any such trust shall be distributed to the
         Partners from time to time, in the discretion of the liquidator, in the
         same proportions as the amount distributed to such trust by the
         Partnership would otherwise have been distributed to the Partners
         pursuant to this Agreement); or

                            (ii) withheld to provide a reserve for Partnership
         liabilities (contingent or otherwise), provided that such withheld
         amounts shall be distributed to the Partners as soon as the liquidator
         determines, in its discretion, that such amounts are no longer
         necessary to be retained.

                  (d) Except as otherwise provided in this Agreement, (i) each
Partner shall look solely to the assets of the Partnership for the return of its
Capital Contributions and shall have no right or power to demand or receive
property other than cash from the Partnership and (ii) no Limited Partner shall
have priority over any other Limited Partner as to the return of its Capital
Contributions. Subject only to any applicable provisions of the Act, in
conjunction with the dissolution of the Partnership, no Partner shall have any
obligation to contribute to or reimburse the Partnership for any deficit in such
Partner's Capital Account.

                  TRANSFERABILITY OF GENERAL PARTNER'S INTEREST

                  SECTION 10.1.  Transferability of General Partner's
Interest.

                  (a) Except as otherwise provided herein, the General Partner
may not Transfer all or any portion of its Interest to any Person without the
prior approval of the Required Partners.

704007.15


<PAGE>




                  (b) In connection with any Transfer permitted hereunder, the
General Partner may admit a transferee as a general partner of the Partnership
without further action by any partner or any other Person, and such transferee
shall be deemed admitted to the Partnership as a general partner of the
Partnership immediately prior to the Transfer and shall continue the business of
the Partnership without dissolution.

                  (c) Notwithstanding, the foregoing, the General Partner agrees
that no Transfer contemplated by this Section 10.1 shall be effected if such
Transfer would jeopardize the status of the Partnership as a partnership for
federal income tax purposes.

                  (d) In connection with any Transfer permitted hereunder, all
expenses, including attorneys' fees and expenses, incurred by the Partnership in
connection with such Transfer shall be fully borne by the General Partner or the
General Partner's transferee. In addition, the General Partner or the General
Partner's transferee shall indemnify the Partnership in a manner reasonably
satisfactory to the Limited Partners against any losses, claims, damages,
liabilities or expenses to which the Partnership may become subject arising out
of or based upon any false representation or warranty made by, or breach or
failure to comply with any covenant or agreement of, the General Partner or the
General Partner's transferee in connection with such Transfer.

                  SECTION 10.2.  Removal of the General Partner.

                  (a) In the event of fraud, gross negligence, willful
misconduct, or an Event of Default by the General Partner, the General Partner
may be removed by written notice (a "Removal Notice") from Limited Partners
(other than any Limited Partner that is an Affiliate of the General Partner)
representing 66.67% of the aggregate Capital Contributions of all Limited
Partners (other than any Limited Partner that is an Affiliate of the General
Partner).

                  (b) Upon the removal of the General Partner pursuant to
Section 10.2(a), (i) the Partnership shall immediately and automatically be
terminated, and (ii) the Carried Interest shall not be payable.

                  (c) The removal of the General Partner pursuant to Section
10.2(a) is not the exclusive remedy of the Partnership or the Limited Partners
for any fraud, gross negligence, willful misconduct, or an Event of Default by
the General Partner.

                  SECTION 10.3. Withdrawal of the General Partner. Except as
otherwise provided in this Article X, the General Partner may not withdraw from
the Partnership prior to its dissolution.


                                   ARTICLE XI

                 TRANSFERABILITY OF A LIMITED PARTNER'S INTEREST

                  SECTION 11.1. Restrictions on Transfer. Prior to 18 months
from the Closing Date, no Transfer of all or any portion of a Limited Partner's
Interest (including some or all of its rights or obligations hereunder) may be
made (other than to an Affiliate of the Limited Partner) without the prior
written consent of the General Partner in its absolute discretion. After 18
months from the Closing Date, a Limited Partner may transfer all or a portion of
its Interest upon the prior written consent of the General Partner. If the
General Partner does not consent to such Transfer (unless the General Partner
withholds its consent because of evidence that the proposed transferee has a
reputation of committing acts of moral turpitude), the General Partner shall
terminate the Partnership and distribute the Shares to the Partners, and within
six months of such distribution the Limited Partner shall pay the Carried
Interest with respect to the Shares distributed. Subject to the Act, no Transfer
shall relieve the transferor of any of its obligations under this Agreement
without the written consent of the General Partner.

                  SECTION 11.2. Expenses of Transfer; Indemnification. All
expenses, including attorneys' fees and expenses, incurred by the General
Partner or the Partnership in connection with any Transfer shall be fully borne
by the transferring Limited Partner or such Limited Partner's transferee. In
addition, the transferring Limited Partner or such transferee shall indemnify
the Partnership and the General Partner in a manner reasonably satisfactory to
the General Partner against any losses, claims, damages, liabilities or expenses
to which the Partnership or the General Partner may become subject arising out
of or based upon any false representation or warranty made by, or breach or
failure to comply with any covenant or agreement of, such transferring Limited
Partner or such transferee in connection with such Transfer.

                  SECTION 11.3.  Recognition of Transfer.

                  (a) The Partnership shall not recognize for any purpose any
purported Transfer of all or any portion of a Limited Partner's Interest
(including some or all of its rights or obligations hereunder) and no transferee
of all or any portion of such Interest shall be admitted as a Limited Partner
hereunder unless:

                  (1) the provisions of Sections 11.1, 11.2 and 11.3(b) shall
         have been complied with;

                  (2) the General Partner shall have been furnished with the
         documents effecting such Transfer, in form and substance satisfactory
         to the General Partner, executed and acknowledged by both transferor
         and the transferee;

                  (3) such Transfer shall have been made in accordance with all
         applicable laws and regulations and all necessary governmental consents
         shall have been obtained and requirements satisfied, including the
         Transfer having been made pursuant to an exemption from the Securities
         Act of 1933 and in compliance with the provisions of New York Corporate
         Securities Law or any other applicable state real estate or securities
         laws or regulations, and such Transfer shall not jeopardize the
         availability of the Partnership's exemption from registration in
         connection with the original offering and sale of Interests referred to
         in Section 12.4(a);

                  (4) such Transfer will not cause a termination of the
         Partnership for federal income tax purposes;

                  (5) the books and records of the Partnership shall have been
         changed (which change shall be made as promptly as practicable) to
         reflect the admission of such Limited Partner;

                  (6) all necessary instruments reflecting such admission shall
         have been filed in each jurisdiction in which such filing is necessary
         in order to qualify the Partnership to conduct business or to preserve
         the limited liability of the Limited Partners; and

                  (7) the General Partner shall have received such advice and
         opinions from counsel to the transferor and counsel to the Partnership
         as the General Partner shall deem

704007.15


<PAGE>



         appropriate to determine that the Transfer complies with the
         requirements of clauses (3) and (4) above.

                  (b) Each transferee, as a condition to its admission as a
Limited Partner, shall execute and acknowledge such instruments, in form and
substance satisfactory to the General Partner, as the General Partner deems
necessary or desirable to effectuate such admission and to confirm the agreement
of such Limited Partner to be bound by all the terms and provisions of this
Agreement with respect to any rights and/or obligations represented by the
Interest acquired by such Limited Partner. The admission of any such Limited
Partner shall not require the approval of any Limited Partner.

                  SECTION 11.4. Transfers During a Fiscal Year. If any Transfer
of a Partner's Interest shall occur at any time other than the end of a Fiscal
Year, the distributive shares of the various items of Partnership income, gain,
loss and expense as computed for tax purposes and the distributions of the
Partnership shall be allocated between the transferor and the transferee
consistent with applicable requirements under Code Section 706; provided that no
such allocation shall be effective unless the transferor and the transferee
shall have agreed to reimburse the General Partner for any incremental
accounting fees and other expenses incurred by the General Partner in making
such allocation. Neither the General Partner nor the Partnership shall incur any
liability for making allocations and distributions in accordance with the
provisions of this Section 11.4.

                  SECTION 11.5. Withdrawal of a Limited Partner. Except as
otherwise provided in this Article XI, a Limited Partner may not withdraw from
the Partnership prior to its dissolution.


                                   ARTICLE XII

                                  MISCELLANEOUS

                  SECTION 12.1.  Amendment to the Agreement.

                  Except as otherwise provided in this Section 12.1, this
Agreement may be amended by the General Partner with the approval of Limited
Partners representing a majority of the aggregate Capital Contributions of all
Limited Partners; provided that no amendment of this Agreement shall:


704007.15


<PAGE>



                  (1)  without the approval of all the Limited Partners,
         amend this Section 12.1,

                  (2) without the approval of the affected Limited Partner, (w)
         increase the liability of a Partner beyond the liability of such
         Partner expressly set forth in this Agreement or otherwise modify or
         affect the limited liability of such Partner, (x) decrease the Interest
         of any Partner (other than as provided in this Agreement), (y) change
         the Capital Contributions of any Partner (other than as provided in
         this Agreement) or (z) change the method of distribution or allocations
         made under Article VI to any Partner (other than as provided in this
         Agreement), or

                  (3) without the approval of Partners having Capital
         Contributions representing the percentage of Capital Contributions
         specified in any provision of this Agreement required for any action or
         approval of the Partners, amend such provision.

                  SECTION 12.2. Approvals. To the extent permitted by applicable
law, each Limited Partner agrees that the written approval of the Required
Partners shall bind the Partnership and each Limited Partner and shall have the
same legal effect as the written approval of each Partner, for purposes of
granting the approval of the Limited Partners with respect to any proposed
action of the Partnership, the General Partner or any of its Affiliates that
specifically requires such approval.

                  SECTION 12.3.  Consultation with the Limited Partners.

                  (a) The General Partner shall consult on a quarterly basis
with the Limited Partners (other than Limited Partners who are Affiliates of the
General Partner) on any material Partnership matters.

                  (b) Notwithstanding anything else contained in this Section
12.3, the Limited Partners shall not possess or exercise any power that, if
possessed or exercised by a General Partner, would constitute participation in
the control of the business of the Partnership.

                  SECTION 12.4.  Investment Representation.  Each Limited
Partner, by executing this Agreement, represents and warrants
that the following statements are true:

                  (a) it understands and accepts that the offering and sale of
Interests is intended to be exempt from Registration

704007.15


<PAGE>



under the Securities Act of 1933, as amended (the "Securities Act"), by virtue
of Section 4(2) of the Securities Act and that the Partnership will make a
notation in its records as to the nontransferability of the Interests without
the prior consent of the General Partner and place a legend on any certificates
evidencing the Interests to the effect that the Interests may not be transferred
in violation of the Securities Act;

                  (b) it understands and accepts that the offering and sale of
Interests is intended to be exempt from registration under the securities laws
of the state or states in which the offer and sale are deemed to be made, by
virtue of a transactional exemption set forth therein;

                  (c) it has such knowledge and experience in business, tax and
financial matters so as to enable it to utilize the information made available
to it in connection with the offering of the Interests in order to evaluate the
merits and risks of an investment in the Interests and to make an informed
investment decision with respect thereto;

                  (d) it is an "accredited investor" within the meaning of Rule
501 under the Securities Act;

                  (e) it is making its investment in the Partnership for its own
account and not for the account of others and is not investing with the present
intention of selling, distributing, transferring or reallocating all or any
portion of its investment and, while the disposition of its investments is
always subject to its own control, presently intends to hold the same until the
Partnership is terminated;

                  (f) it understands that transferability of its Interest is
restricted and the Limited Partner cannot expect to have any liquidity with
respect to its investment;

                  (g) unless the General Partner has previously determined that
the admission of the Limited Partner will not cause assets of the Partnership to
be "plan assets" within the meaning of Department of Labor Regulation
ss.2510.3-101, it is not an employee benefit plan subject to Title I of the
Employee Retirement Income Security Act of 1974;

                  (h) it understands that no federal or state agency has
recommended or endorsed the purchase of the Interests or passed on the adequacy
or accuracy of the information set forth in this Agreement;


704007.15


<PAGE>



                  (i) it has had the opportunity, at a reasonable time prior to
its purchase of the Interests, to ask questions and receive answers concerning
the terms and conditions of an investment in the Partnership and to obtain any
additional information, financial or otherwise, which it deems appropriate in
order to evaluate an investment in the Partnership; and

                  (j) it is treated as a single investor for purposes of the
Investment Company Act of 1940.

                  SECTION 12.5.  Representations.

                  (a) The General Partner represents and warrants to the Limited
Partners, and covenants and agrees, that:

                                    (i)  the General Partner is a limited
         liability company, duly formed, validly existing and in good standing
         under the laws of the State of Delaware and is duly qualified and in
         good standing in each jurisdiction in which the character and location
         of its properties or the nature of its business activities makes such
         qualification necessary, and has all requisite power and authority to
         execute, deliver and perform this Agreement;

                                    (ii) the execution, delivery and performance
         by the General Partner of this Agreement is within its power, has been
         authorized by all necessary action and does not contravene any
         provision of its organizational documents;

                                    (iii) this Agreement is a valid and binding
         obligation of the General Partner;

                                    (iv) the execution, delivery and performance
         of this Agreement by the General Partner does not conflict with or
         result in a breach of any of the provisions of, or constitute a default
         under, any bond, note or other form of indebtedness, indenture,
         mortgage, deed of trust, loan agreement or similar instrument, any
         lease or other agreement or contract to which it is a party or by which
         any of its property may be bound or any applicable law or order, rule
         or regulation or any court or governmental agency that has jurisdiction
         over it or any of its property;

                                    (v) there are no actions, suits or
         proceedings pending or, to the knowledge of the General Partner,
         threatened against or affecting the General Partner or, to the
         knowledge of the General Partner or its members,

704007.15


<PAGE>



         which would bring into question the validity of the transactions
         contemplated by this Agreement or might result in a material adverse
         change in the business, assets or condition of the General Partner;

                                    (vi) during the term of the Partnership, the
         General Partner will not subject any of its Interests in the
         Partnership (or its respective right in the future to receive income or
         profits from the Partnership) to the claims of any creditors;

                                    (vii) during the term of the Partnership,
         the General Partner shall defend at its sole cost and expense any claim
         made against its Interest in the Partnership (or its respective right
         in the future to receive income or profits from the Partnership)
         resulting from the respective indebtedness or the claims of any
         creditors of the General Partner;

                                    (viii) during the term of the Partnership,
         the General Partner shall promptly notify the Limited Partners as to
         (A) any claim asserted or threatened against the General Partner's

         receive income and profits from the Partnership), or against any assets
         of the Partnership or against any of the respective members of the
         General Partner and (B) any other obligation entered into by the
         General Partner or any of the respective members of the General
         Partner, where such claim or obligation in the judgment of the General
         Partner might reasonably have a material adverse effect on the
         Partnership or the Interest of the Limited Partners in the Partnership;

                                    (ix) there are no terms governing the
         investment of the Sister Partnerships (whether in a partnership
         agreement, a side letter or otherwise) that are more favorable to any
         limited partner of any Sister Partnership than the terms of this
         Agreement, and in the event that any term governing the investment of
         the Sister Partnerships is subsequently granted (whether in a
         partnership agreement, a side letter or otherwise) that is more
         favorable to any limited partner of any Sister Partnership than the
         Limited Partner, the General Partner shall promptly grant to the
         Limited Partner such more favorable term; and

                                    (x) the General Partner is not aware of any
         material inaccuracy in the written material concerning Mark

704007.15


<PAGE>



         Centers Trust and the properties controlled by Affiliates of the
         General Partner prepared by the General Partner or its Affiliates and
         delivered to the Limited Partners prior to the date hereof.

                  (b) Each of the Limited Partners represents and warrants
individually and respectively to the General Partner that:

                                    (i) it is duly formed and validly existing
         under the laws of the jurisdiction of its formation or is an individual
         and has all requisite power and authority to execute, deliver and
         perform this Agreement;

                                    (ii) the execution, delivery and performance
         of this Agreement by it are within its power, and for Limited Partners
         that are not individuals, have been authorized by all necessary action
         and do not contravene any provision of its articles of formation or
         governance;

                                    (iii) this Agreement is a valid and binding
         obligation of such Limited Partner; and

                                    (iv) the execution, delivery and performance
         of this Agreement by it does not conflict with or result in a breach of
         any of the provisions of, or constitute a default under, any bond, note
         or other form of indebtedness, indenture, mortgage, deed of trust, loan
         agreement or similar instrument, any lease or other agreement or
         contract to which it is a party or by which any of its property may be
         bound or any applicable law or order, rule or regulation or any court
         or governmental agency that has jurisdiction over it or any of its
         property.

                  SECTION 12.6. Involvement of Ross Dworman & Kenneth F.
Bernstein in the Partnership. Ross Dworman and Ken Bernstein, by their
respective signatures attached hereto, each respectively acknowledges and agrees
as follows: (a) that they are the sole members of the General Partner; (b) that,
absent his death or disability, each shall at all times during the term of the
Partnership actively participate in such capacity on behalf of the General
Partner in the management of the Partnership; and (c) that, without the consent
of the Required Partners and absent death or disability of either of them, the
ownership of interests in the General Partner shall not be voluntarily
transferred, pledged or otherwise conveyed other than among such individuals or

the consent of the Required Partners, Ross

704007.15


<PAGE>



Dworman and Kenneth F. Bernstein each agree that they shall commit sufficient
attention, time and effort to the management and operation of the General
Partner and through such entity to the management and operation of the
Partnership and its Investments as is then reasonably appropriate or required in
light of the then activities of the Partnership. Ross Dworman and Kenneth
Bernstein will not exercise the options described in Section 6.1(e)(v) prior to
36 months after the Closing Date.

                  SECTION 12.7. Successors; Counterparts. This Agreement (i)
shall be binding as to the executors, administrators, estates, heirs and legal
successors of the Partners and (ii) may be executed in several counterparts with
the same effect as if the parties executing the several counterparts had all
executed one counterpart.

                  SECTION 12.8. Governing Law; Severability. This Agreement
shall be governed by and construed in accordance with the laws of the State of
Delaware without giving effect to the principles of conflict of laws thereof. In
particular, it shall be construed to the maximum extent possible to comply with
all of the terms and conditions of the Act. If, nevertheless, it shall be
determined by a court of competent jurisdiction that any provision or wording of
this Agreement shall be invalid or unenforceable under said Act or other
applicable law, such invalidity or unenforceability shall not invalidate the
entire Agreement. In that case, this Agreement shall be construed so as to limit
any term or provision so as to make it enforceable or valid within the
requirements of applicable law, and, in the event such term or provision cannot
be so limited, this Agreement shall be construed to omit such invalid or
unenforceable provisions. If it shall be determined by a court of competent
jurisdiction that any provision relating to the distributions and allocations of
the Partnership or to any fee payable by the Partnership is invalid or
unenforceable, this Agreement shall be construed or interpreted so as (i) to
make it enforceable or valid and (ii) to make the distributions, allocations and
fees as closely equivalent to those set forth in this Agreement as is
permissible under applicable law.

                  SECTION 12.9. Filings. Following the execution and delivery of
this Agreement, the General Partner shall promptly prepare any documents
required to be filed and recorded under the Act, and the General Partner shall
promptly cause each such document to be filed and recorded in accordance with
the Act and, to the extent required by local law, to be filed and recorded or
notice thereof to be published in the appropriate place in each state in which
the Partnership may hereafter establish a place of

704007.15


<PAGE>



business. The General Partner shall also promptly cause to be filed, recorded
and published such statements of fictitious business name and other notices,
certificates, statements or other instruments required by any provision of any
applicable law of the United States or any state or other jurisdiction which
governs the conduct of its business from time to time.

                  SECTION 12.10. Power of Attorney. Each Limited Partner does
hereby constitute and appoint the General Partner as its true and lawful
representative and attorney-in-fact, in its name, place and stead to make,
execute, sign, deliver and file (i) a Certificate of Limited Partnership of the
Partnership, any amendment thereof required because of an amendment to this
Agreement or in order to effectuate any change in the membership of the
Partnership, (ii) any amendments to this Agreement pursuant to Section 12.1, and
(iii) all such other instruments, documents and certificates which may from time
to time be required by the laws of the United States of America, the State of
Delaware or any other state, or any political subdivision or agency thereof, to
effectuate, implement and continue the valid and subsisting existence of the
Partnership or to dissolve the Partnership.

                  The power of attorney granted hereby is coupled with an
interest and shall (a) survive and not be affected by the subsequent death,
incapacity, disability, dissolution, termination or bankruptcy of the Limited
Partner granting the same or the transfer of all or any portion of such Limited
Partner's Interest and (b) extend to such Limited Partner's successors, assigns
and legal representatives.

                  SECTION 12.11. Waiver of Action for Partition. Each of the
Partners irrevocably waives any right that it may have to maintain any action or
other legal proceeding for partition with respect to any of the Partnership's
assets.

                  SECTION 12.12. Headings. Section and other headings contained
in this Agreement are for reference purposes only and are not intended to
describe, interpret, define or limit the scope or intent of this Agreement or
any provision hereof.

                  SECTION 12.13. Additional Documents. Each Partner, upon the
request of the General Partner, agrees to perform all further acts and execute,
acknowledge and deliver any documents that may be reasonably necessary to carry
out the provisions of this Agreement.

                  SECTION 12.14.  Goodwill.  No value shall be placed on
the name or goodwill of the Partnership.

                  SECTION 12.15. Notices. All notices, requests and other
communications to any party hereunder shall be in writing (including telecopier
or similar writing) and shall be given to such party (and any other person
designated by such party) at its address or telecopier number set forth on
Schedule A hereto or such other address or telecopier number as such party may
hereafter specify for the purpose by notice to the General Partner (if such
party is a Limited Partner) or to all the Limited Partners (if such party is the
General Partner). Each such notice, request or other communication shall be
effective (i) if given by telecopier, when transmitted to the number specified
pursuant to this Section 12.15 and the appropriate answerback or confirmation is
received, (ii) if given by mail, 72 hours after such communication is deposited
in the mails with first class postage prepaid, addressed as aforesaid or (iii)
if given by any other means, when delivered at the address specified pursuant to

                  SECTION 12.16. Enforcement Costs. In the event any Partner
defaults in the performance of its obligations under this Agreement, the

reasonable costs and expenses (including, without limitation, reasonable
attorneys' fees and costs) expended or incurred in connection with enforcing its
rights under this Agreement.

                  SECTION 12.17. No Third Party Rights. The obligations or
rights of the Partnership or any Partners to make or require any Capital
Contribution under this Agreement shall not grant any rights to or confer any
benefits upon any Person who is not a Partner other than Mark Centers Trust
pursuant to Section 5.1. The provisions of this Agreement are intended only for
the regulation of relations among Partners, putative Partners and the
Partnership. This Agreement is not intended for the benefit of non-Partner
creditors and does not grant any rights to non-Partner creditors other than
Mark Centers Trust pursuant to Section 5.1.
