                  claims thereunder in any way arising prior to the execution of
                  this Agreement. Those requirements include that Executive
                  understands and acknowledges that by executing this Agreement:

                           a. Executive is knowingly and voluntarily waiving any
                  and all rights and claims he may have under the ADEA and

                  addition to anything of value to which he is already entitled;

                           c. Executive has been advised to consult with an
                  attorney prior to executing this Agreement;

                           d. Executive has carefully read this Agreement, knows
                  and understand its contents and its significance, and intends
                  to be bound by its terms;

                           e. Executive has been given a period of 21 days from
                  the receipt of this Agreement to consider its contents and
                  ramifications and his decision to sign it (although it may be
                  executed and returned prior to that if desired).

                           f. Executive will be given seven days following
                  execution of this Agreement to revoke it by notifying the

                  become effective or enforceable and no payments will be made
                  under this Agreement until that seven day revocation period
                  has expired.

                  any and all claims as stated herein which he could or may make
                  on his own behalf, but also those claims solely with respect

                  other person or entity (including Executive's spouse and
                  family members).

                  It is further understood and agreed that this entire Agreement
                  is not to be construed as an admission of liability by the
                  Company or the Company Released Parties. Further, the payment
                  of monies under this Agreement does not constitute an
                  admission by or on behalf of the Company or the Company
                  Released Parties that you are entitled to any payment pursuant
                  to any policy or practice.

                  Nothing in this Agreement shall be construed as a release,
                  waiver or other relinquishment by you of (i) any claims,
                  demands, actions or liabilities based upon Executive's rights
                  pursuant to this Agreement, (ii) any indemnity to which the
                  Executive may be entitled pursuant to the terms and conditions
                  of the Company's Certificate of Incorporation, By-laws or any
                  directors' and officers' liability insurance policy in effect
                  as of the

<PAGE>   6

                  Effective Date (including, without limitation, any right the
                  Executive may have to retain separate counsel and
                  reimbursement by the Company in connection therewith) and
                  (iii) any right to collect any vested benefits to which he may
                  be entitled under the Company's 401(k) retirement plan.

                  the Effective Date it releases and discharges the Executive of
                  and from any and all claims, demands, actions or liability

                  Effective Date, whether known or unknown, arising out of or in
                  connection with the Executive's employment by the Company, or
                  the termination of such employment, except for any claims,
                  demands, actions or liability based upon the Company's rights
                  pursuant to this Agreement. Notwithstanding the foregoing, the

9.       GENERAL PROVISIONS.

         9.1.     BINDING AGREEMENT. This Agreement shall be binding upon and

                  Executive's personal or legal representatives or successors if
                  the Executive dies while any amounts would still be payable to
                  him hereunder, benefits would still be provided to his family
                  hereunder, or rights would still be exercisable by him
                  hereunder as if he had continued to live. Such amounts shall
                  be paid to the Executive's estate, such benefits shall be
                  provided to the Executive's family, and such rights shall
                  remain exercisable by the Executive's estate in accordance
                  with the terms of this Agreement. This Agreement shall not
                  otherwise be assignable by the Executive.

         9.2.     SUCCESSORS. This Agreement shall inure to and be binding upon

                  consolidation, lease or otherwise, by agreement in form and
                  substance satisfactory to the Executive, to assume this
                  Agreement expressly. This Agreement shall not otherwise be
                  assignable by the Company. In the event that it is
                  impracticable for a successor of the Company to perform the
                  Company's obligations under paragraph 1.1(d), of this
                  Agreement, the Company shall pay to the Executive, in a lump
                  sum payment without discounting to present value, an amount
                  equal to the aggregate of all remaining payments due under
                  such paragraph 1.1(d).

                  breach of this Agreement shall be deemed a waiver of a
                  subsequent breach.

similar to the distributions of Interim Capital Transactions contained in
Section 6.3 and, to the extent the ultimate distributions to be made on

Capital Account. In the event the Net Profits to be allocated are less than the
aggregate excess described above, each Partner will be allocated that portion of
the Net Profits to be allocated pursuant to this Section 6.6, the numerator of
which is the differential between its distribution and its Capital Account and
the denominator of which is the aggregate differential for all Partners; and

              (b) Thereafter, the balance of Net Profits from Interim Capital
Transactions shall be allocated 75% to the Limited Partners (to be shared by
them pro rata based upon their relative Percentage Interests) and 25% to the
General Partner;

              (c) Net losses from Interim Capital Transactions shall be
allocated among the Partners as follows:

                  (1) First, to the Partners in proportion to their Capital
Accounts, until their Capital Accounts are reduced to zero; and

                  (2) Thereafter, the balance of Net Losses, if any, shall be
allocated among the Partners pro rata in accordance with their Percentage
Interests.

         SECTION 6.7 - ALLOCATION OF NET PROFITS AND NET LOSS FROM CAPITAL
TRANSACTIONS UPON A LIQUIDATION OF THE PARTNERSHIP.

              (a) Except as provided in Section 6.8, all Net Profits of the
Partnership in connection with a dissolution and winding up of the Partnership
shall be allocated to the Partners in the following manner and priority:

                  (1) First, to the Class A Limited Partner until the positive
balance in the Capital Account of the Class A Limited Partner is equal to the
sum of the Unrecovered Capital of the Class A Limited Partner and the 6%
Preferred Return;

                  (2) Then, to the Class B Limited Partners until the positive
balance in the Capital Account of the Class B Limited Partners is equal to the
Unrecovered Capital of the Class B Limited Partners.

                  (3) Then, to the Class A Limited Partner until the positive
balance in the Capital Account of the Class A Limited Partner is increased by an
amount equal to the Balance of the Class A Limited Partner's 9% Preferred
Return;

<PAGE>   16

                  (4) Then, to the Class B Limited Partners until the positive
balance in the Capital Account of the Class B Limited Partners is increased by
an amount equal to the 9% Preferred Return;

                  (5) Then, to the General Partner until the positive balance of
the Capital Account of the General Partner is equal to the Unrecovered Capital
of the General Partner;

                  (6) Then, to the Limited Partners until the positive balance
in the Capital Account of the Limited Partners is increased by an amount equal
to the Balance of the Limited Partners' 15% Preferred Return under Section
6.3(g);

                  (7) Then, to the Class B Limited Partners and the General
Partner until the positive balance in their Capital Accounts is increased by the
Balance of the Special 15% Priority that is or was distributed to such Partners
under Section 6.3(h);

                  (8) Next, to the General Partner until the positive balance in
the Capital Account of the General Partner is increased by an amount equal to
the 15% Preferred Return;

                  (9) Thereafter, to the Partners in accordance with, and in
proportion to the amounts received, or to be received, by them pursuant to
Section 6.3(j).

              (b) Net Losses from Capital Transactions upon a liquidation of the
Partnership shall be allocated first to those Partners with positive Capital
Account balances, pro rata, until such Capital Account balances have been
reduced to zero. The balance of Net Losses, if any, shall be allocated, pro
rata, in accordance with the Partners' Percentage Interests.

         SECTION 6.8 - MINIMUM GAIN CHARGEBACK; QUALIFIED INCOME OFFSET.
Notwithstanding any allocation in this Article VI:

              (a) No Net Loss and no Net Loss from Capital Transactions shall be
allocated to any Partner to the extent that such allocation would cause or
increase the amount of a deficit balance in such Partner's Capital Account at a
time when any other Partner has a positive balance in his Capital Account. Any
Net Loss and any Net Loss from Capital Transaction not allocable to a Partner by
reason of the foregoing sentence shall be allocated to any remaining Partners
having positive Capital Account balances until such balances have been reduced
to zero.

              (b) In the event that: (i) any Partner or Partners unexpectedly
receives any adjustment, allocation, or distribution described in Treasury
Regulation Sections 1.704-1(b)(2)(ii) (d)(4), (5) or (6), and (ii) such
adjustment, allocation or distribution causes or increases a deficit balance in
such Partner's or Partners' Capital Accounts) as of the end of the Partnership
taxable year to which such adjustment, allocation or distribution relates, then,
notwithstanding the provisions of Sections 6.5, 6.6 and 6.7 hereof, items of
gross income (consisting of a pro rata portion of each item of gross income) for
such taxable year and each subsequent year shall be allocated among all such
Partners in proportion to such deficit balances or increases in such deficit
balance created or caused by such adjustment, allocation or distribution, as the
case may be, to eliminate such deficit balances or increases in such deficit
balances, as the case may be, as quickly as possible.

              (c) In the event that during a Partnership taxable year there is a
net decrease in the Partnership "Minimum Gain" (within the meaning of Treasury
Regulation Section 1.704-1(b)(4) (iv)(c)), then, prior to any other allocation
under Sections 6.5, 6.6 and 6.7, of all items of income and gain, each Partner
must be allocated items of income and gain for such year (and, if necessary, for
subsequent years) in proportion to, and to the extent of, an amount equal to the

<PAGE>   17

greater of (i) the portion of such Partner's share of the net decrease in
Partnership Minimum Gain during such year that is allocable to the disposition
of Partnership Property subject to one or more nonrecourse liabilities of the
Partnership, or (ii) the deficit balance in such Partner's Capital Account at
the end of such year (determined before any allocation of Partnership income,
gain, loss, deduction, or Code Section 705(a)(2)(H) expenditures for such year
and after making the adjustments required by Treas. Reg. ss.1.704-1(b)
(2)(ii)(d).

         For purposes of clauses (a), (b) and (c) of this Section 6.8, the
Capital Account balances of all Partners shall be adjusted as provided in
Treasury Regulation Section 1.704-1(b)(2) (ii)(d) and to reflect each Partner's
share of the Partnership minimum gain as provided in Treasury Regulation Section
1.704-1 (b)(4)(iv) as of the end of the Partnership taxable year.

         SECTION 6.9 - MONTHLY SEGMENTS; ALLOCATIONS AMONG PARTNERS.

              (a) Except as otherwise provided in this Agreement, all income,
gains, losses, deductions, credits and cash flow that are allocated or
distributed to the Limited Partners shall be allocated or distributed among them
in proportion to their respective Percentage interest as measured on the last
day of the appropriate monthly segment.

              (b) The Partnership shall divide each fiscal year into 12 monthly
segments for the purpose of allocating income, gains, losses, deductions,
credits and distributions to Partners who were members of the Partnership at the
end of each such monthly segment (hereinafter "segment"). In any case, each
segment shall be based on calendar months so that segments shall end on the last
day of each month whether or not the fiscal year is less than 12 months. Any
Partner entering the Partnership during any month shall be deemed to enter the
Partnership on the first day of the month and the income, gain, loss, deduction
and distributions, if any, attributable to such Partner will be allocated to
such Partner based on the closing of the books method.

              (c) Any allocations or distributions made hereunder to the Class H
Limited Partners shall be shared between them in accordance with their relative
Percentage Interests in the Partnership.

         SECTION 6.10 - NO NEGATIVE RESTORATION. In no event shall any Partner,
by reason of his or its execution of this Agreement, be liable to pay for any
loss beyond the amount of his or its Capital Contribution, or be personally
liable for any debts of the Partnership except to the extent provided by the
Act, or this Section 6.10. Each Limited Partner understands, however, that to
the extent required by applicable partnership law, if he or it receives the
return in whole or in part of his or its Capital Contribution, he may be liable
to the Partnership for any sum, not in excess of such return with interest
necessary to discharge the Partnership's liabilities to creditors.

         SECTION 6.11 - ACCOUNTING. The Partnership shall use the method of
accounting directed by the General Partner. The fiscal year of the Partnership
shall be the calendar year except that in any year the Partnership shall
commence or terminate for federal income tax purposes, the then current fiscal
year shall either begin on the date of commencement or end on the date of such
termination, as the case may be.

<PAGE>   18

         SECTION 6.12 - BOOK-UP PROVISIONS. Notwithstanding anything else
contained herein, if the General Partner in its sole discretion so determines,
upon the receipt of additional Capital Contributions from Partners, the assets
of the Partnership shall be valued by the General Partner, any unrecognized gain
or loss with respect to the Partnership's assets shall be allocated to the
Capital Accounts of the Partners in accordance with Treasury Regulation Section
1.704-1(b)(2)(iv)(f), the Capital Accounts of the Partners shall be maintained
in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(g), and the
allocations of items of taxable income, gain, deduction and loss with respect to
such assets shall be made in accordance with Treasury Regulation Section
1.704-1(b)(4)(i).

         SECTION 6.13 - SECTION 704(C) ALLOCATIONS. In accordance with Code
section 704(c) and the Regulations thereunder, income, gain, loss and deduction
with respect to any property contributed to the capital of the Partnership,
including DMCS Shares, shall, solely for tax purposes, be allocated among the
Partners so as to take into account the variation between the adjusted basis of
the property to the Partnership for federal income tax purposes and its initial
gross value. Allocations pursuant to this Section 6.13 are solely for purposes
of federal, state and local taxes and shall not affect or be taken into account
in computing any Partner's Capital Account or share of Net Profits or Net Losses
or other items or distributions pursuant to any provision of this Agreement.

         SECTION 6.14 - SPECIAL 35% PROFITS LIMITATION. Notwithstanding anything
contained in this Agreement to the contrary, the individual Class B Limited
Partner's profits interest in the Partnership (as such term is defined in Code
section 4946) (when combined with the indirect profits interest in the
Partnership held by Mitchell Kupperman) shall in no event exceed 354. In the
event that the Individual Class B Limited Partner's profits interest in the
Partnership were to exceed 354 (when combined with the indirect profits interest
of Mitchell Kupperman), the Partners agree and acknowledge that any return in
excess of such 35% profits interest in the Partnership shall be reallocated away
from the Individual Class B Limited Partner and to The Nirenberg Family
Charitable Foundation, or any successor to the Class B Limited Partner interest
held by The Nirenberg Family Charitable Foundation, so that after such
reallocation has been effectuated the individual Class B Limited Partner's
profits interest in the Partnership (when combined with the indirect, profits
interest in the Partnership held by Mitchell Kupperman) is no greater than 35%.

         SECTION 7.1 - TAX MATTERS PARTNER. The Partnership hereby designates
the General Partner to act as the Tax Matters Partner in accordance with
Internal Revenue Code Section 6231, as the same may be, from time to time,
amended. In the event that the General Partner ceases, for any reason, to be a
general partner, or if it shall resign as Tax Matters Partner, the remaining
General Partner, if any, shall be the Tax Matters Partner, and, if there is no
remaining General Partner, then a Super Majority of the Partners shall designate
the Partner to serve as Tax Matters Partner.

         SECTION 8.5 - REPRESENTATIONS BY GENERAL PARTNER. The General Partner
does hereby represent and warrant that:

              (a) the appropriate documents have been or will be filed which
will constitute the Partnership as duly organized and validly existing under the

will not constitute a violation of any law, administrative regulation or court
decree.

         SECTION 8.6 - OTHER ACTIVITIES. The General Partner shall devote only
such time to the Partnership's business as shall be reasonably required. The
Limited Partners hereby acknowledge that the partners of the General Partner are
officers of DMCS and that as such, a substantial portion of their time will be

General Partner, or the partners of the General Partner, for breach of the
General Partner's fiduciary obligation to the Partnership due, or relating to

against the said officers by virtue of any willful misconduct by said officers.

         SECTION 8.7 - PERIODIC REPORTING. The General Partner shall furnish to
the Limited Partners, within 10 days after they are received by the General

                            ------------------------

         SECTION 9.1 - ACTIONS OF THE GENERAL PARTNER. Whenever in this
Agreement or any other agreement contemplated herein, the General Partner is
permitted or required to make a decision (i) in its "discretion" or "sole
discretion", with "complete discretion" or under a grant of similar authority or
latitude, the General Partner shall be entitled to consider only such interest
and factors as it desires and shall have no duty or obligation to consider any
interest of or factors affecting the Limited Partners or their assigns or (ii)
in its "good faith" or under another express standard, the General Partner shall
be subject to only such express standard and shall not be subject to any other
or different standards imposed by the Act, any other applicable law, statute,
rule or regulation, or any other agreement contemplated herein. Each Limited
Partner and each assignee hereby agrees that any standard of care or duty
imposed in this Agreement or any other

<PAGE>   21

agreement contemplated herein or under the Act or any other applicable law,
rule, or regulation, shall be modified, waived or limited in each case as
required to permit the General Partner to act under this Agreement or any other
agreement contemplated herein and to make any decision pursuant to the authority
prescribed in this Section 9.1, so long as such action or decision does not
constitute gross negligence, malfeasance or fraud and is not reasonably believed
by the General Partner to be inconsistent with the overall purposes of the
Partnership. The General Partner may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, bond, debenture or other paper
or document believed by the General Partner to be genuine and to have been
signed or presented by the proper party or parties. The General Partner may
consult with legal counsel, accountants, appraisers, management consultants,
investment bankers and other consultants and advisors selected by the General
Partner. The opinion of such person as to matters which the General Partner
believes to be within such person's professional or expert competence shall be
full and complete authorization and protection in respect of any action taken or
suffered or omitted by the General Partner in good faith and in accordance with
such opinion.

         SECTION 9.2 - THIRD PARTY RELIANCE ON AUTHORITY OF THE GENERAL PARTNER.
The signed statement of the General Partner reciting that the General Partner
has authority to undertake any act or has the necessary votes or consents of the
Partners to take any such act, when delivered to any third party, including any
lender or purchaser (including any purchaser of the DMCS Shares from the
Partnership) ("Third Party"), shall be all of the evidence such Third Party
shall need concerning the capacity of such General Partner and any such Third
Party shall be entitled to rely upon such statement and shall not be required to
inquire further as to any of the facts contained in such statement, said facts
being deemed to be true insofar as such Third Party is concerned (provided,
however, that such Third Party may not rely upon such statement and deem it to
be true if such Third Party has actual knowledge to the contrary). After
delivering such statement, the General Partner by its signature alone, may sign
any instrument and bind the Partnership and the Partnership Property just as
though all of the Partners had also signed. The Limited Partners and/or their
assigns hereby waive any and all defenses or other remedies that may be
available against any such Third Party or other person to contest, negate or
disaffirm any action of the General Partner in connection with any such
statement provided for in this Section 9.2. Each contract, agreement, deed,
mortgage, security agreement, promissory note or other instrument or document
executed by the General Partner, or its representative, with respect to the
business or property of the Partnership shall be conclusive evidence in favor of
any and every person relying thereon or claiming thereunder that (a) at the time
of the execution and delivery thereof, this Agreement was in full force and
effect, (b) such instrument or document was duly executed in accordance with the
terms and provisions of this Agreement and is binding upon the Partnership, and
(c) the General Partner, or its representative, was duly authorized and
empowered to execute and deliver any and every such instrument or document for
and on behalf of the Partnership. Such statement shall not, however, have any
effect between the Partners unless the action in question was in fact authorized
pursuant to this Agreement.

                   ------------------------------------------

         SECTION 10.1 - AUTHORITY OF LIMITED PARTNERS. Except as set forth in
this Agreement, or as permitted by the General Partner, no Limited Partner
(unless such Limited Partner shall also be a General Partner acting in such
capacity) shall:

              (a) take part in the management of the business or transact any
business on behalf of the Partnership; or

              (b) have the power to execute instruments or documents on behalf
of the Partnership or bind the Partnership in any manner.

         SECTION 10.2 - RIGHTS OF LIMITED PARTNERS. Each Limited Partner (or its
duly authorized agent) shall have the right:

              (a) under reasonable circumstances to inspect at the office of the
Partnership during ordinary business hours and to copy at the requesting
Partner's expense:

                  (1) the list of the names and business addresses of the
Partners; and
                  (2) the Certificate of Limited Partnership, including
amendments, and powers of attorney utilized in the execution of such documents;

                  (3) Partnership income tax returns for the three most recent
years; and
                  (4) the written Partnership Agreement with all Amendments; and
                  (5) financial statements of the Partnership for the three most
recent years.

              (b) to obtain from the General Partner from time to time on
reasonable demand just and reasonable information including the state of the
business and financial condition of the Partnership and copies of the
Partnership tax returns after such become available.

         SECTION 10.3 - ASSIGNMENT BY PARTNERS. Except as provided in Article
XI, or Sections 10.5 or 5.2, and except for any transfer by the Class A Limited
Partner of all or any portion of its interest in the Partnership to any
Affiliate of such Limited Partner, no Limited Partner may transfer his interest
in the Partnership, voluntarily or involuntarily, unless such Limited Partner
complies with the right of refusal provisions contained in Section 10.4. No such
assignee shall become a Partner of the same class as his assignor unless:

              (a) such person executes an instrument reasonably satisfactory to
the General Partner accepting and adopting the terms and provisions of this
Agreement; and

              (b) in the case of assignments other than by operation of law, the
assignor states his intention in writing to have his assignee become a Partner
of the same class; and

              (c) such assignee executes a Power of Attorney as described in
Article XII and such other documents as the General Partner may reasonably
require; and

              (d) all expenses and costs relating to the assignment, including
the General Partner's attorneys' fees, shall be paid by the assignor or
assignee; and

<PAGE>   23

              (e) except for employees of DMCS who acquire their Class B Limited
Partner interest in the Partnership pursuant to Section 5.2, the transferee is
not a person or entity (i) which owns, operates or franchises convenience stores
and/or gasoline stations (a "Competing Person") or (ii) which controls, is
controlled by, or is under common control with a Competing Person.

         If the foregoing conditions are not complied with, the Partnership need
not recognize such assignment for any purpose. The assignment by a Limited
Partner or by an assignee of a Limited Partner, shall become effective on the
day of receipt by the General Partner of evidence of such assignment and of
compliance with this Section 10.3.

         SECTION 10.4 - RIGHT OF FIRST REFUSAL. Except with respect to (i)
transfers permitted pursuant to Article XI or Section 5.2, or (ii) transfers by
the Class A Limited Partner of all or, a portion of its interest in the
Partnership to any Affiliate of such Limited Partner, in the event a Limited
Partner desires to sell all or any part of his interest in the Partnership, the
Limited Partner may sell such interest only in accordance with this Section. In
the event a Limited Partner receives a bona fide offer ("Offer") to purchase his
interest (excluding an offer to purchase from another Partner), then such
Limited Partner shall provide the General Partner with a copy of the Offer. In
the event a Limited Partner has not received an Offer but desires to sell all or
any part of his interest in the Partnership, he may give the General Partner a
written statement indicating the price and term: that such Partner would be
willing to sell such interest (also an "Offer"). The General Partner shall then
have a period of twenty (20) days ("Notice Period") within which to give written
notice to the Limited Partner of its intention to purchase such interest (or
cause the Partnership to purchase such interest) in accordance with the terms of
the Offer. Failure to notify the Limited Partner within the Notice Period shall
be deemed a rejection. If the Offer is rejected, the selling Limited Partner
shall be free to consummate such sale in accordance with the Offer for a period
of one hundred and twenty (120) days next following the end of the Notice
Period, provided that all of the requirements of Section 10.3 are complied with.
Failure to consummate such sale within the one hundred and twenty (120) day
period shall cause such interest to be resubjected to the right of first refusal
set forth in this Section. In the event more than one Partner accepts the Offer,
then each such accepting Partner shall be entitled to purchase a proportionate
amount of the interest being sold.

         SECTION 10.5 - RIGHT TO GIFT INTEREST. Notwithstanding the transfer
restrictions contained in this Article X, The Nirenberg Family Charitable
Foundation, Inc. (the "Foundation") shall be permitted to transfer its Class B
interest in the Partnership by gift so long as such transfer is necessary or
required to avoid the imposition on the Foundation, or on any of its affiliates,
of the "excess business holdings" excise tax under Code section 4943.

Interest in the Partnership is greater than 30% may sell all or a portion of his
or its limited partnership interest in the Partnership, so long as such sale is
made in accordance with the following provisions:

<PAGE>   24

              (a) The Limited Partner must notify the General Partner, in
writing, of his or its desire to sell his or its interest in the Partnership. On
behalf of the Limited Partnership, the General Partner will thereafter negotiate
with the Limited Partner to acquire the Limited Partner's interest in the
Partnership. If, within 30 days after receipt of such written notice by the
General Partner, the General Partner and the Limited Partner do not reach an
agreement as to the acquisition by the Partnership of the interest of the
Limited Partner in the Partnership, the Limited Partner will thereafter have the
right to offer his or its Limited Partnership interest to a third party.

              (b) if the Limited Partner receives an offer to purchase his or
its Limited Partnership interest from a third party (the "Offer"), the Limited
Partner shall comply with the provisions of Section 10.4 above.

              (c) If the Limited Partner and the General Partner cannot agree on
the terms on which the Partnership would acquire the Limited Partner's interest
in accordance with Section 11.1(a) herein, and if the Limited Partner is unable
to find a third party purchaser within 60 days thereafter, then the Limited
Partner will have the right to either: (i) demand that the Limited Partnership
be dissolved, and that the assets of the Partnership be distributed to the
Partners in accordance with Article XV of this Agreement; or (ii) cause the
assets of the Limited Partnership to be sold. In the event the assets of the
Partnership are distributed, the Limited Partner will also have the right to
request that DMCS file a registration statement on the Limited Partner's behalf
on terms and conditions that are customarily applicable to registration rights
granted to the holders of convertible securities and, in such event, General
Partner will use its best efforts to cause such registration statement to be
filed and become effective.

  Restriction Against Transfers By General Partner; Removal of General Partner
  ----------------------------------------------------------------------------

         SECTION 14.1 - REMOVAL OF GENERAL PARTNER. The General Partner may be
removed as the General Partner only for gross negligence or willful misconduct.
Removal of a General Partner may be effected only by delivery of a written
notification to, the General Partner requesting removal of the General Partner,
which notification must be signed by a Super Majority of the Partners. The
notification shall set forth in reasonable detail the cause for removal, and
shall bear the witnessed and notarized signature of each Limited Partner joining
in said notification. The notification must also set forth the name and address
of a general partner which the signatory Limited Partners propose in
substitution for the removed General Partner.

         SECTION 14.2 - EFFECT OF REMOVAL. The removal of the General Partner
shall be effective upon election of a successor General Partner. A General
Partner so removed shall be entitled to receive that amount that would be due
him had the assets of the Partnership been sold at their fair market value as of
the date of the removal and such proceeds were distributed among the Partners in
accordance with Section 6.4. Such removed General Partner shall not be entitled
to any other distributions or to exercise any of the rights of a Partner. The
Percentage Interest of the removed General Partner shall, as of the effective
date of such removal, be vested in the successor General Partner if the removed
General Partner was the sole General Partner.

         SECTION 14.3 - SUCCESSOR. The consent of a Super Majority is required
to choose an additional or successor General Partner, but no sole remaining
General Partner may be removed unless and until a successor General Partner
shall have been elected. In the event that the sole remaining General Partner is
removed and no successor shall be elected within 90 days of the effectiveness of
such removal, then the Partnership shall be dissolved.

         SECTION 14.4 - TRANSFER OF GENERAL PARTNER'S INTEREST. The General
Partner may not sell, transfer (voluntarily or by operation of law), assign or
encumber by pledge or otherwise any part of its general partnership interest,
nor may more than 50% of the beneficial ownership of the General Partner be sold
or transferred (other than to persons who are already partners of the General
Partner on the date hereof), without first obtaining the written consent of a
Super Majority of the Limited Partners, which consent shall not be unreasonably
withheld or delayed.

              (b) A disposition by the Partnership of more than 1,115,245 DMCS
Shares in the aggregate (including all prior dispositions of DMCS Shares by the
Partnership), except that

<PAGE>   27

upon the happening of such event, the General Partner can extend the Partnership
for reasonable periods of time upon the vote of a Super Majority of the
Partners.

              (c) The bankruptcy, insolvency, death, incompetency or other event
set forth in Section 34-28 of the Connecticut General Statutes ("Event of
Withdrawal") by, of, on to the General Partner except that the Partnership shall
not be dissolved if either:

                  (1) a remaining General Partner, if any, continues the
business of the Partnership, or

                  (2) within 90 days followings such event a Super Majority of
Limited Partners agree in writing to continue the business of the Partnership
and to the appointment of one or more successor General Partner.

              (d) A determination by the General Partner to dissolve the
Partnership.

              (e) The failure to elect a successor to a sole remaining General
Partner who has withdrawn, dissolved or been removed within the time required by
Section 14.3.

              (f) Any Limited Partner electing pursuant to Section 11.1(c)(i) to
cause the Partnership to be dissolved.

         SECTION 15.2 - PRIORITY OF DISTRIBUTION. If the Partnership shall
terminate for any reason, the General Partner shall proceed to the liquidation
of the Partnership, subject to the rights of the Class A Limited Partner under
Section 15.6 hereof to elect to receive certain distributions in kind, and the
proceeds of such liquidation shall be applied and distributed in the following
order of priority:

              (a) To expenses of liquidation, and to creditors, including
Partners who are creditors, to the extent permitted by law, in satisfaction of
liabilities of the Partnership, except for distributions due Partners under
Sections 34-20(d) and 34-27(d) of the Act.

              (b) To the setting up of any reserves which the General Partner
may deem reasonably necessary for any contingent or unforeseen liabilities or
obligations of the Partnership or of the General Partner (other than any
liabilities for which the General Partner is not entitled to indemnification
under Article XIII or in respect of which the General Partner must indemnify the
Partners or the Partnership, in each case because of the General Partner's gross
negligence or willful misconduct) arising out of, or in connection with, the
Partnership. Such reserve shall be paid over by the General Partner to a
commercial bank or an attorney-at-law of the State of Connecticut, as escrowee,
to be held for the purpose of disbursing such reserves in payment of any of the
aforementioned contingencies, and, at the expiration of such period, as the
General Partner shall deem advisable, to distribute the balance thereafter
remaining in the manner hereinafter provided.

              (c) To Partners and former Partners in satisfaction of liabilities
for distributions under Sections 34-20(d) and 34-27(d) of the Act.

              (d) Any balance then remaining shall be distributed among all
Partners in accordance with Section 6.4.

<PAGE>   28

         SECTION 15.3 - PERIOD OF DISSOLUTION. A reasonable time (but in no
event later than the latter of the end of the taxable year of the liquidation of
the Partnership or 90 days after the date of the termination) shall be allowed
for the orderly liquidation of the assets of the Partnership and the discharge
of liabilities to creditors so as to enable the General Partner to minimize the
normal losses attendant upon a liquidation.

         SECTION 15.4 - STATEMENT. Each of the Partners shall be furnished with
a statement prepared by the Partnership's then independent accountants, which
shall set forth the assets and liabilities of the Partnership as of the date of
complete liquidation. Upon the General Partner complying with the foregoing
distribution plan (including payment over to an escrowee if there are sufficient
funds therefor), the General Partner shall execute and cause to be filed a
Certificate of Cancellation of the Partnership.

         SECTION 15.5 - LIABILITY FOR CAPITAL CONTRIBUTIONS. The General Partner
shall not be personally liable for the return of the Capital Contributions of
the Limited Partners or any portion of such Capital Contribution. Any such
return, if any, shall be made solely from Partnership assets.

         SECTION 15.6 - DISTRIBUTION OF ASSETS. (a) Upon any termination or
dissolution of the Partnership, the Class A Limited Partner shall have the
right, upon written notice to the General Partner (the "Notice"), to elect to
receive its distribution in the form of the assets of the Partnership if the
Class A Limited Partner shall determine in its reasonable judgment that the net
sales value of the Partnership's assets would be insufficient to enable such
Limited Partner to recover its Unrecovered Capital and the 6% Preferred Return.
In such event, the assets of the Partnership shall be valued at their fair
market sales value which, in the case of any DMCS Shares held by the
Partnership, shall equal the average closing sale price of such stock for the
ten (10) trading days immediately preceding the date of termination or
dissolution as reported by the National Association of Securities Dealers, Inc.
Automated Quotation System or if then listed on an exchange, the principal
exchange. The Class A Limited Partner may give the Notice up to 150 days prior
to a scheduled termination or dissolution of the Partnership, and for such
purposes (but not for purposes of determining the value of the assets for the
distribution or the right of the Class A Limited Partner ultimately to receive
its distribution in kind, which shall be determined as of the date of
termination or dissolution), the fair market sales value of the assets of the
Partnership shall be determined as of the date of the Notice (and in the case of
any DMCS Shares, shall equal the average closing sales price of such stock for
the ten trading days immediately preceding the date of the Notice as reported by
the National Association of Securities Dealers, Inc. Automated Quotation system,
or if then listed on an exchange, the principal exchange).

             (b) Notwithstanding the Class A Limited Partner's right to receive
DMCS Shares contained in Section 15.6(a), if the General Partner, within 60 days
after receipt of the Notice enters into a binding contract on behalf of the
Partnership, to sell the assets of the Partnership (the "Sales Contract") at a
net sales value which would allow the Class A Limited Partner to recover its
Unrecovered Capital plus the 6% Preferred Return, then the General Partner shall
be free to consummate such sale in accordance with the Sales Contract for a
period of ninety (90) days next following the date of the Sales Contract.
Failure to consummate such

<PAGE>   29

sale within the ninety day period shall entitle the Class A Limited Partner to
receive the assets of the Partnership pursuant to Section 15.6(a).
