Item 5. Other Events

Settlement Agreements

         On October 6, 1997, Dart Group Corporation ("Dart") announced
settlements (the "Settlements") with Herbert H. Haft and Ronald S. Haft pursuant
to a settlement agreement with Herbert H. Haft (the "HHH Settlement Agreement"),
a First Supplemental Settlement Agreement with Ronald S. Haft (the "First
Supplemental Agreement") and a Second Supplemental Settlement Agreement with
Ronald S. Haft (the "Second Supplemental Agreement"). The closing of the
transactions contemplated in the Settlement Agreement, First Supplemental
Agreement and Second Supplemental Agreement, which have been approved by Dart's
Board of Directors, is subject to court approval. A press release announcing the
Settlements is incorporated by reference and attached hereto as Exhibit 99.1.

         If the Settlements are approved by the Delaware Court of Chancery, then
upon closing Herbert H. Haft will (a) sell to Dart all of his shares of, and
options to purchase, Dart Class A Common Stock, and his capital stock of Dart's
subsidiaries Trak Auto Corporation and Crown Books Corporation, (b) retire from
all of his positions with Dart and its subsidiary corporations, (c) relinquish
his claim to voting control of Dart, and (d) terminate his employment agreement
with Dart. In addition, all outstanding litigation and disputes between Dart
and Herbert H. Haft will be resolved. As consideration for the Settlements,
Dart  will pay Herbert H. Haft approximately $28 million upon closing, of which 
amount $9.25 million may be deferred until June 1, 1998 if the closing occurs 
before then. Dart also will make a $10 million loan to a partnership owned by 
Herbert H. Haft and Ronald S. Haft. The HHH Settlement Agreement, the First
Supplemental Agreement and the Second Supplemental Agreement are each
incorporated by reference and attached hereto as Exhibits 99.2, 99.3 and 99.4,
respectively.

         In connection with the Second Supplemental Agreement, Dart and Ronald
S. Haft entered into an Amendment to Voting Trust Agreement amending the Voting
Trust Agreement dated as of October 6, 1995 among Dart, Ronald S. Haft, Larry G.
Schafran and Sidney B. Silverman as initial voting trustees. A copy of the
Amendment to Voting Trust Agreement is incorporated by reference and attached 
hereto as Exhibit 99.5.

         The closing of the Settlements is not expected to occur before December
1997 and could be delayed until sometime in 1998. There can be no assurance as
to whether or when court approval of the Settlement will be obtained, and there
can be no assurance that the closing of the Settlement will occur. The
description of the Settlements and the Amendment to Voting Trust Agreement set
forth herein does not purport to be complete and is qualified in its entirety by
the provisions of the HHH Settlement Agreement, the First Supplemental
Agreement, the Second Supplemental Agreement and the Amendment to Voting Trust
Agreement.

Composition of Board of Directors

         On October 21, 1997 certain changes were made in the composition of
Dart's Board of Directors as more fully set forth in the Press Release issued
by Dart on October 22, 1997, a copy of which is incorporated herein by
reference and attached hereto as Exhibit 99.6.

FOR IMMEDIATE RELEASE

               DART GROUP ANNOUNCES SETTLEMENT WITH HERBERT HAFT
               AND APPOINTMENT OF RICHARD B. STONE AS ACTING CEO

        Landover, MD... October 17, 1997 ... The Executive Committee of the
Board of Directors of Dart Group Corporation (NASDAQ: DARTA), consisting of
Senator Richard B. Stone, Douglas M. Bregman, Esq. and Bonita A. Wilson, today
announced that it has entered into a Settlement Agreement with Herbert Haft.
If the settlement is approved by the Delaware Court of Chancery, then upon
closing Herbert Haft will retire from all of his positions with Dart and its
subsidiary corporations.  The positions he will relinquish include his
positions as Chairman and Chief Executive Officer of Dart, Co-Chairman of
Shoppers Food Warehouse Corp., and Chairman of Trak Auto Corporation and Crown
Books Corporation.  Herbert Haft also will relinquish his claim to voting
control of Dart upon closing of the settlement.

        Dart's Board has appointed Richard B. Stone to serve as Acting Chief
Executive Officer pending closing of the settlement with Herbert Haft.  Mr.
Stone also has been named Chairman of the Executive Committee of Dart's Board
of Directors.

        At the closing of the settlement, Herbert Haft will sell to the Company
all 122,747 of his shares of Dart Class A Common Stock and options to purchase
a total of approximately 129,750 shares of Dart Class A Common Stock, and
substantially lesser holdings in Trak Auto and Crown Books.  Herbert Haft's
employment agreement with Dart will terminate at closing, and all outstanding
litigation and disputes between Dart and Herbert Haft will be resolved.  Mr.
Haft will also assign certain real estate interests to the Company.

        Dart will pay Herbert Haft approximately $28 million if the settlement
closes, of which amount $9.25 million may be deferred until June 1, 1998 if the
closing occurs before then.  Dart also will make a $10 million loan to a
partnership owned by Herbert and Ronald Haft, which loan will be personally
guaranteed by Ronald Haft and will be secured by such partnership's interests
in three shopping centers located in suburban Washington, D.C. and by a
one-half indirect interest in an office building in Lanham, Maryland leased by
Shoppers Food Warehouse Corp.  Herbert Haft will also receive an additional
$11.6 million from escrowed funds previously paid by Dart to Ronald Haft as
part of its October 1995 settlement with Ronald Haft (and $700,000 interest on
those funds).

        Closing of the settlement between Dart and Herbert Haft is subject to
final and non-appealable action by the Delaware Court of Chancery or the
Delaware Supreme Court approving all of the terms of the settlement,
terminating certain putative derivative actions pending with respect to Dart in
the Delaware Court of Chancery, and approving the October 1995 settlement
between Dart and Ronald Haft and the supplemental settlement between Dart and
Ronald Haft.





                                     - 1 -
<PAGE>   2
The closing of the settlement is not expected to occur before December 1997 and
could be delayed until sometime in 1998.  There can be no assurance as to
whether or when court approval of the settlement will be obtained, and there
can be no assurance that the closing of the settlement will occur.

        Dart also announced that it has entered into supplemental settlement
arrangements with Ronald Haft.  These arrangements will permit the shares now
held in a Voting Trust for the benefit of Ronald S. Haft to be transferred to
the Corporation upon the later of the closing and January 1998, which will
terminate the Voting Trust.  Assuming this occurs, no shares of Dart's Class B
voting stock will be outstanding.  It is contemplated that the shares of Dart's
Class A common stock, which now are non-voting, will have the right to vote in
the election of directors and other matters after the closing of Dart's
settlement with Herbert Haft.

        Dart's supplemental settlement arrangements with Ronald Haft also will
permit the completion of bankruptcy plans of reorganization for the
partnerships owning Dart's headquarters building in Landover, Maryland and a
warehouse leased by Dart's subsidiary, Trak Auto Corporation, in Bridgeview,
Illinois.  Under these bankruptcy plans, the Corporation will pay a total of
$7.0 million to reduce outstanding institutional mortgage loans on these
properties, which will thereafter be wholly-owned by Dart affiliates.  The
supplemental settlement arrangements with Ronald Haft also will provide for a
$2.2 million payment to Dart from escrowed funds previously earmarked for
Ronald Haft.

        A portion of the cost of these transactions may be allocated to Trak
Auto Corporation and, possibly, Crown Books Corporation, which are subsidiaries
of Dart.  No such allocations have yet been determined.

        Herbert Haft said, "Senator Stone has had a distinguished career as a
U.S. Senator, a diplomat, a lawyer and a businessman.  I wish him all the best
and for the success of the companies."

        Dart is the majority owner of Trak Auto Corporation (NASDAQ: TRKA) and
Crown Books Corporation (NASDAQ: CRWN), and the sole owner of Shoppers Food
Warehouse Corp. and Total Beverage Corp.

his positions as an officer or director of Dart and each Dart Affiliate, and
the Employment Agreement shall terminate without further liability of either
party to the other thereunder.  On the Closing Date, Dart and HHH shall execute
and deliver a Termination of Employment Agreement in the form of EXHIBIT 10.

          (c)  Continued Indemnification.  Notwithstanding the termination of
the Employment Agreement, Dart hereby confirms and agrees that HHH shall be
entitled, after he shall cease to hold directorships and/or officerships with
Dart and the Dart Affiliates, to enjoy the benefit of the indemnification
obligations of Dart under the certificate of incorporation and bylaws of Dart
in each case as in effect on the date hereof, and under the Delaware General
Corporation Law and the Indemnification Agreement for indemnification against
any liabilities arising out of his being or having been an officer, employee or
director of Dart or any Dart Affiliate; provided, however, that this SECTION
2.1(c) shall not waive any defenses Dart or any Dart Affiliate might have to
any claim by HHH to indemnification.  Dart further agrees that prior to the
Closing Date it shall not, and thereafter shall not, amend, supplement or
otherwise modify, and shall not permit any Dart Affiliate to amend, supplement
or otherwise modify, its certificate of incorporation or bylaws if such
amendment, supplement or other modification would adversely affect the
indemnification rights of HHH thereunder.  Neither Dart nor any Dart Affiliate
shall amend or modify any policy of directors and officers liability insurance
that has been in existence prior to the date of this Agreement in any way that
would adversely affect HHH's rights thereunder. To the fullest extent permitted
by Delaware law, Dart hereby unconditionally and irrevocably agrees to pay,
within five

required by law, a Schedule 13D indicating such beneficial ownership, or (B)
within six (6) months after such announcement, the transaction contemplated by
such memorandum of intent or agreement in principle or a similar type of
written understanding has not become the subject of a definitive acquisition or
similar agreement.  Notwithstanding the prohibitions contained in this SECTION
2.1(d) with respect to the acquisition or ownership of Restricted Securities of

categories by both Moody's and Standard & Poor's.  Interest and discounts
earned and collected on the foregoing investments are not required to be
reinvested but may be retained by Dart or the applicable Dart Affiliate and
used in the business.  Dart shall issue to HHH on the fifth day of every
calendar month a written report certified as true and correct to the best of
their knowledge and belief by Dart's Chairman of the Executive Committee and
its Chief Financial Officer showing for the preceding calendar month (A) all
gross proceeds received from the transactions referred to in the immediately

reinvestments made during such month and the amounts of earned and collected

reinvested as provided above.  Dart will not, and will not permit any of its
Affiliates to create or suffer to exist, any lien, claim, charge or encumbrance
on any of the foregoing investments and non-cash assets until after HHH shall
have received all the funds payable to him at Closing.  Nothing in the
preceding provisions of this SECTION 2.1(f) shall preclude the transfer by a
Dart Affiliate to Dart of any net proceeds as defined above, so long as Dart
holds, invests and reports about such proceeds it receives and complies with
the foregoing the same as such Dart Affiliate would have been required to had
such net proceeds not been so transferred or paid by way of dividend.

of its Affiliates to make, any Restricted Payment as defined in Event of

Affiliates, to amend its Certificate of Incorporation; and (c) Dart will not,

net proceeds realized on such issue, sale

or other transfer are held, invested, used and reported on as required by
SECTION 2.1(f) for release at Closing to Dart or its Affiliate, as the case may
be, but only if HHH shall have been paid all cash due him at the Closing

          (b)  Deliveries by Dart.  On the Closing Date, subject to applicable
tax withholding in the maximum amount of $2,536,390 as specified in EXHIBIT 20:

                         (i)      Cash Payment and Note Deliveries by Dart. (A)
        Dart shall pay to HHH, in cash, in immediately available funds, the
        amount of $18,829,000, (less the Vehicular Setoff and less the amount
        payable to LGH pursuant to the direction set forth in the last sentence
        of this Section 2.2(b)(i)(A)).  Notwithstanding the foregoing, if prior
        to the Closing Dart has made $1,259,381 of tax withholdings from its
        settlement payment to LGH for her five (5) putative Dart/SFW stock
        options and paid such amount to tax agencies in respect of HHH's tax
        liability in respect of such settlement payment, then HHH hereby
        irrevocably directs that $629,692 of the amount payable by Dart to him
        under Section 2.2(b)(i)(A) shall instead be payable to LGH on the
        Closing Date provided, however, that if prior to Closing Dart shall
        have closed the disposition of assets, merger or other transaction
        pursuant to which Dart or any Dart Affiliate ceases to own or control
        all or any part of SFW, except for sales of assets in the ordinary
        course of business as heretofore conducted, then Dart shall pay HHH, in
        cash, at





                                     - 17 -
<PAGE>   23
        closing, the additional sum of $9,250,000 and the June Note (as defined
        below) shall not be issued.

                 (B)     If and only if Dart shall not have closed the
        disposition of interests in SFW described in Section 2.2(b)(i)
        immediately above, Dart shall execute and deliver to HHH its
        full-recourse secured note (the "June Note"), in the form of EXHIBIT 21
        hereto, in the principal amount of $9,250,000, payable on the earlier
        of June 1, 1998 or a Special Transaction, which June Note shall bear
        simple interest from and after the Closing Date, payable monthly in
        arrears, at 5% per annum; provided that June Note shall be subject to
        mandatory prepayment upon the occurrence of any Special Transaction.

                 (C)     [Intentionally omitted]

                 (D)     To secure the June Note Dart will (I) execute and
        deliver to a bank or brokerage firm mutually acceptable to Dart and
        HHH, as Security Perfection Agent, its pledge and security agreement in
        the form of EXHIBIT 22 hereto, pledging to HHH the 122,747 Dart Class A
        Shares purchased by Dart from HHH pursuant to this Agreement (the
        "Pledged Class A Shares") and shares of common stock of Trak (or, if
        Dart no longer holds Trak stock, then shares of common stock of the
        corporation which holds Dart's shares of stock in SFW, which is SFW
        Holding Corp.) and (II) deliver to such Security Perfection Agent
        certificates for such shares, registered in the name of Dart, duly
        endorsed for transfer accompanied by appropriate signed stock powers
        (in either case, with signatures guaranteed by Medallion Signature
        Guaranty), it being understood that the number of shares pledged to HHH
        and delivered to the Security Perfection Agent as collateral for the
        June Note shall be that number of shares the value of which,
        determined, in the case of Trak, by reference to the average of the
        closing





                                     - 18 -
<PAGE>   24
        bid/asked prices on the thirty (30) trading days immediately prior to
        the Closing Date or any later date of determination, equals at least
        $20,000,000 (or such larger amount, if any, as may be required to
        comply with applicable laws and regulations) determined by reference to
        the average of the closing bid/asked prices on the thirty (30) trading
        days immediately prior to the Closing Date or such later date of
        determination and in the case of any other shares determined by a fair
        and reasonable method in compliance with applicable law as determined
        by majority vote of the independent directors of Dart.

                 (E)     [Intentionally omitted]
           
                 (F)     [Intentionally omitted]

                 (G)     Dart shall pay in immediately available funds, the sum
        of the amount of all HHH's accrued but unpaid base salary from the last
        date of payment to the Closing Date.

                 (ii)    Vehicles.  In full satisfaction of any obligation by
        Dart to provide HHH with a car under the Employment Agreement, Dart
        shall transfer clear and good title (except for any encumbrances
        created by HHH) to each of the Vehicles to HHH, registered in his name
        and titled in the District of Columbia, in exchange for which Dart
        shall receive a total of $62,000.  This transaction shall occur at any
        time on or prior to the Closing Date as HHH shall elect by written
        notice to Dart.  It is anticipated that Dart will (A) receive $15,000
        of the purchase price from RMH and (B) if the transaction occurs at
        Closing, reduce the sum referred to in SECTION 2.2(b)(i)(a) by the
        amount of $47,000 (the "Vehicular Setoff") as payment of the other
        $47,000 of the purchase price.  HHH may, in his sole discretion, elect
        not to purchase the Vehicles as contemplated by this SECTION 2.2(b)(ii)
        if any of them has been stolen or damaged or if he wishes for any other
        reason not to purchase the Vehicles.

                 (iii)   Estoppel Certificates.  Subject to prior due diligence
        satisfactory to Dart's Affiliates (which will be completed prior to
        Closing), Dart will cause each Dart Affiliate which is a lessee of
        retail space in either or both of the Landmark and Fair City properties
        to deliver to HHH or his designee estoppel/no-controversy certificates
        relating to space leased or subleased by it, in the form of EXHIBIT 17
        hereto, in exchange for the estoppel/





                                     - 19 -
<PAGE>   25
        no-controversy certificates contemplated by SECTION 2.2(a)(x) above;

                 (iv)    Garnishment.  After (A) a final order of satisfaction
        or (B) a stipulation of dismissal signed by First Union has been
        entered by the Circuit Court for Prince George's County terminating all
        writs of garnishment of wages issued on behalf of First Union against
        Dart, Trak and Crown, Dart will reasonably cooperate with HHH to have
        all of HHH's wages previously withheld by Dart, Trak and Crown and
        deposited with the Clerk of the Circuit Court for Prince George's
        County (inclusive of interest earned on such sums, if any, while on
        deposit with the Court) turned over to HHH.

                 (v)     Mutual Release.  Dart shall, and Dart shall cause each
        of the Dart Affiliates listed on EXHIBIT 14 to, execute and deliver to
        HHH a Mutual Release in the form of EXHIBIT 14;

                 (vi)    Life Insurance.  Dart will permit HHH, after the
        Closing, to (A) continue the life insurance policies (the "Insurance
        Policies") on his life set forth in EXHIBIT 23 in whole or in part, at
        his election, if and to the extent such continuation is permitted by
        those policies without cost to Dart or any Dart Affiliates and (B)
        assign the Insurance Policies to GGH upon delivery by GGH to Dart of
        security documentation (including financing statements on Form UCC-1)
        satisfactory to Dart to secure loans described below that have not been
        repaid; provided, however, that the cash value of the policies and all
        death benefits thereunder will be subject to a first priority perfected
        security interest to secure HHH's obligation on a non-recourse basis to
        repay Dart for all premiums heretofore paid on the Insurance Policies,
        which obligation the parties acknowledge is in the total amount of
        $1,068,313 as of the date of this Agreement; and provided further that
        HHH (and his assigns) shall be responsible on a non-recourse basis for
        outstanding policy loans and shall be prohibited from taking new policy
        loans until Dart has been fully repaid the premiums that it paid.  GGH
        shall not be required to deliver such security documentation to Dart if
        HHH shall have delivered to Dart an





                                     - 20 -
<PAGE>   26
        irrevocable designation of Dart as sole beneficiary under each
        Insurance Policy, which irrevocable designation shall have been
        acknowledged by the issuer of such Insurance Policy and if such
        designation is made, Dart shall deliver to GGH any cash proceeds
        received by it under the Insurance Policies that, in the aggregate,
        exceed $1,068,313.  HHH shall not be personally liable for the loans
        listed in EXHIBIT 23.

                 (vii)   Escrow Funds.  Dart shall notify the Escrow Agent that
        Dart has no objection to the delivery to HHH (or to any other Person as
        HHH may instruct in writing) (A) all Escrow Funds (as defined in the
        Escrow Agreement) in the amount of $11,619,274.00, and (B) if the
        Escrow Agent has received written consent from RSH to do so, $700,000
        of the interest earned or accrued on the Escrow Funds since October 6,
        1995;

                 (viii)  Legal Fees.  Dart shall reimburse HHH in the manner
        provided in SECTION 7.1, up to $90,000 for reasonable fees of DPW for
        reviewing filings made by Dart with the Securities and Exchange
        Commission and assisting HHH with Board meetings of Dart and Dart
        Affiliates since September 1994, if HHH shall have provided Dart with
        reasonable evidence to support such reimbursement.

                 (ix)    Closing Representation Certificates.  Dart shall
        execute and deliver the Closing Representation Certificates in the
        forms attached hereto as EXHIBIT 24.

                 (x)     Total Option.  Dart will deliver to HHH an option to
        purchase an interest in Total, which shall be the same as that to which
        RMH was declared entitled in his litigation with Dart in the United
        States District Court for the District of Delaware, mutatis mutandis.
        Such option and the terms of its exercise will be as provided in
        EXHIBIT 25 hereto.

                 (xi)    Dart will, at HHH's instructions, wire cash payable to
        him at Closing to Gloria G. Haft and Davis Polk & Wardwell, in amounts
        and to banks, as instructed in writing by HHH.

        SECTION 3.1.     Closing Process; Interrelationship of Settlements.
(a) Standstill Order.  The parties acknowledge that this Agreement and the
obligation of Dart and each Dart Affiliate to consummate the transactions
contemplated hereby, are subject to compliance with an order of the Delaware
Court of Chancery (the "Standstill Order") entered on December 6, 1995 that
requires Dart to refrain from taking or recognizing specified actions and, in
particular, Section 8 of the Standstill Order that requires Dart to give not
less than seven (7) days' notice of certain "extraordinary transactions" to the
other parties to the lawsuits contesting the Dart/RSH Settlement Agreement.
Within two (2) Business Days after the date of execution and delivery of each
of this Agreement, the Dart/RSH First Supplemental Agreement and the Dart/RSH
Second Supplemental Agreement, Dart shall send written notice of the
transactions contemplated thereby in accordance with the terms of Section 8 of
the Standstill Order.  Notwithstanding any other provision of this Agreement,
neither Dart nor any Dart Affiliate shall be obligated to enter into any
agreement or perform any transaction or action contemplated hereby (other than
SECTION 2.1(a)) until such time as the seven (7) day notice period under
Section 8 of the Standstill Order has expired, or if later, such date as no
temporary restraining order, preliminary injunction, permanent injunction or
other court order is in effect that restrains Dart or any Dart Affiliate from
entering into such agreement or performing such transaction or action.

         (b)   Deliveries on Closing Date.  On the Closing Date, each of the
parties shall simultaneously deliver to each other all of the agreements,
instruments and other documents each is specifically required to deliver to the
other on the Closing Date pursuant to SECTION 2.2 of this Agreement.

the parties may agree on a date mutually acceptable to the parties within
forty-five (45) days after the date on which conditions to closing under
SECTIONS 3.4(a) AND 3.4(b) shall have been fulfilled (or waived in writing by
the party entitled to waive); provided, that neither party shall be obligated
to close unless all of the conditions to such party's obligation to close set

such party in writing.

It is expressly understood that, even though HHH's obligation to close is not
excused by any such failure to perform by Dart, Dart's obligations to HHH in
respect of the Stipulated Duties are not diminished, released or otherwise
affected by the fact that HHH has a duty to close despite Dart's
non-performance.  The occurrence of the Closing shall not waive or alter any of
HHH's rights and HHH shall be entitled to pursue all available remedies against
Dart by reason of any non-performance in respect of the Stipulated Duties,
provided, however, that any recovery by HHH shall be limited to specific
performance and actual money damages for breach.

         (e)   Other Closings.  The closings under the Dart/Other Hafts
Agreement, the Dart/RSH First Supplemental Agreement and the Dart/RSH Second

Dart to the HHH/RSH Tier II Limited Partnership, a Maryland limited
partnership, which will own and pledge to Dart 99% of the equity interests in

occurred (which loan shall be 100% without recourse to HHH), simultaneously
with the Closing, pursuant to the Dart/RSH Second Supplemental Agreement and
the Loan Agreement attached as Exhibit C to the Dart/RSH Second Supplemental
Agreement and (ii) RSH shall concurrently prepay or shall have previously
prepaid in full the $10,000,000 in principal amount of notes issued by him to
HHH which by their terms are required to be prepaid upon receipt by RSH of such
$10 million loan.

         (g)   Dart shall execute and deliver documents acknowledging receipt
of all cash and other property received by it at the Closing.

<PAGE>   35


        SECTION 4.1.     Representations and Warranties of HHH.  HHH will
represent and warrant as follows on the Closing Date and, as to the matters set
forth in clauses (a), (b) and (e) below, represents and warrants the same on
the date hereof:

         (a)   Valid and Binding Obligations.  This Agreement has been duly
executed and delivered by HHH and constitutes a legal, valid and binding
obligation of HHH enforceable against HHH in accordance with its terms, except
as such enforcement may be limited by bankruptcy, insolvency, reorganization or
similar laws of general application affecting the remedies of creditors
generally, and except that, in the discretion of the court, equitable remedies
may not be available for the enforcement thereof.  The Settlement Documents
(other than this Agreement) to which HHH is or will be a party are or, when
executed and delivered by HHH, will be valid and binding obligations of HHH,
enforceable against HHH in accordance with their terms, except as such
enforcement may be limited by bankruptcy, insolvency, reorganization or similar
laws of general application affecting the remedies of creditors generally, and
except that, in the discretion of the court, equitable remedies may not be
available for the enforcement thereof.

         (b)   No Interference.  Except as described on EXHIBIT 26, the
execution, delivery and performance by HHH of each of the Settlement Documents
to which HHH is or will be a party, and the consummation of the transactions
contemplated thereby, will not breach, violate or conflict with any provision
of, give rise to any right of acceleration of any obligation under or
constitute a default under (or an event which with the giving of notice or
lapse of time, or both, would give rise to such a right or constitute such a
default) nor require the consent or waiver of any other party to (i) any
mortgage, lease, note, contract, agreement or instrument to which HHH is a
party or (ii) any law, regulation, order, judgment, writ, decree, decision or
award by which HHH is bound.

         (c)   No Approvals.  Except as described in EXHIBIT 26, no consent,
waiver, release, approval, order or authorization of, or notification to, any
third party or any government or government agency is required in connection
with the execution, delivery or





                                     - 30 -
<PAGE>   36
performance by HHH of the Settlement Documents and the consummation by HHH of
the transactions contemplated thereby.

         (d)   Title.  (i) There are on October 6, 1997 no Liens (as defined
below) created by the signature of HHH or imposed by operation of law against
HHH other than Liens in favor of GGH and Liens on the Dart A Shares included in
the Assets which were originally created to secure First Union Bank ("First
Union Lien").  Except for such Liens, HHH has on October 6, 1997 good and
marketable title to all of the Assets, free and clear of Liens.

         (ii)  HHH will upon Closing have good and marketable title to all of
the assets being transferred by him to Dart at the Closing (the "Assets"), free
and clear of liens, charges, security interests, restrictions, claims or
encumbrances of any kind ("Liens"), and HHH has not taken any action that could
give rise to any such Lien; provided that HHH makes no representation or
warranty with respect to the HHH Warehouse/Office Building Interests except as
set forth in the Assignment of Warehouse Interests.

         (e)   Options.  Except as described in EXHIBIT 26, HHH owns, and at
all times prior to the Closing will own, good and marketable title to all of
the Options free and clear of any Lien.  HHH has not taken and will not take
any action that could give rise to such Lien.  HHH does not own and does not
have any right to acquire any other shares of the capital stock of Dart or any
Dart Affiliate except the Options.  Upon consummation of the transactions
contemplated by this Agreement at the Closing, HHH shall not beneficially own,
directly or indirectly, any interest in any shares of capital stock (or any
right to acquire any shares of capital stock) of Dart or any Dart Affiliate
other than his rights under (and any interests acquired pursuant to) the pledge
and security agreement executed and delivered by Dart pursuant to SECTION
2.2(h)(i).

         (f)   Absence of Certain Liens.  HHH will on the Closing Date have no
liabilities, obligations or commitments, including, without limitation, those
for taxes of any kind, that, if adversely determined or not discharged or
performed by HHH, will create any Lien on or against any of the Assets.





                                     - 31 -
<PAGE>   37
         (g)   No Partnership Commitments.  To the best knowledge of HHH, there
will on the Closing Date be no liability, commitment or obligation of HHH or
any partnership of which HHH is or has been a general partner, that affects or
could affect any of the Assets.

         (h)   No Litigation.  There will on the Closing Date be no actions,
suits, proceedings, investigations or claims pending or, to the knowledge of
HHH, threatened against HHH or, to the knowledge of HHH, any other party, or
involving any of the Assets, that affect or could affect any of the Assets in
any respect, or that relate to any of the transactions contemplated by this
Agreement and that, if successful, could restrain or prohibit the consummation
of such transactions, and neither HHH nor any Assets is subject to any order,
judgment, writ, decree, decision or award that affects or could affect any of
the Assets in any respect; provided that HHH makes no representation or
warranty with respect to the HHH Warehouse/Office Building Interests except as
set forth in the Assignment of Warehouse Interests.

         (i)   HHH does not have the present intention to do any of the
following: (a) apply for, or consent in writing to, the appointment of a
receiver, trustee or liquidator; (b) file a voluntary petition seeking relief
under the Bankruptcy Code or be unable, or admit in writing his inability, to
pay his debts as they become due; or (c) make a general assignment for the
benefit of creditors.

         (j)   The delivery by HHH of certificates at the Closing representing
the Shares in the manner provided in SECTION 2.2(a)(ii) will transfer to Dart
or a Dart Affiliate, as the case may be, good, valid and marketable title to
such shares, free and clear of Liens, except the security interest in stock
securing the June Note.

        SECTION 4.2.     Representations and Warranties of Dart.  Dart will
represent and warrant as follows on the Closing Date and, as to the matters set
forth in clauses (a), (b), (c) and (f) below, on the date hereof:





                                     - 32 -
<PAGE>   38
         (a)   Organization and Good Standing.  Dart is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware.

         (b)   Valid and Binding Obligations.  Assuming that all conditions
precedent to Closing set forth in SECTION 3.3(a) shall have been fulfilled, as
to which no representation or warranty is made, each of (i) the Settlement
Documents, (ii) the note issued by Dart to HHH on the Closing Date and (iii)
the pledge and security agreement provided to HHH on the Closing Date to which
Dart is or will be a party are or, when executed and delivered by Dart will be
the valid and binding obligations of Dart, enforceable against Dart in
accordance with their terms, except as such enforcement may be limited by
bankruptcy, insolvency, reorganization or similar laws of general application
affecting the remedies of creditors generally, and except that, in the
discretion of the court, equitable remedies may not be available for the
enforcement thereof.

         (c)   No Interference.  Except as described in EXHIBIT 27, the
execution, delivery and performance by Dart of the Settlement Documents to
which Dart is or will be a party and the consummation of the transactions
contemplated thereby will not breach, violate or conflict with any provision
of, give rise to any right of acceleration of any obligation under or
constitute a default under (or an event which with the giving of notice or
lapse of time or both would give rise to such a right or constitute such a
default), nor require the consent or waiver of any other party to (i) any
mortgage, lease, note, contract, agreement or instrument to which Dart is a
party or (ii) any law, regulation, order, judgment, writ, decree, decision or
award by which Dart is bound.

         (d)   No Approvals.  Except as described in EXHIBIT 27, no consent,
waiver, release, approval, order or authorization of, or notification to, any
third party or any government or government agency is required in connection
with the execution, delivery or performance by Dart of the Settlement Documents
to which Dart is or will be a party or the consummation by Dart of the
transactions contemplated thereby.





                                     - 33 -
<PAGE>   39

         (e)   No Litigation.  Except as set forth in EXHIBIT 27, there are no
actions, suits, proceedings, investigations or claims pending or, to the
knowledge of Dart, threatened against Dart or, to the knowledge of Dart, any
other party, that relate to any of the transactions contemplated hereby and
that, if successful, could restrain or prohibit the consummation of such
transactions.

         (f)   Absence of Certain Intentions.  Dart does not have the present
intention to do any of the following: (i) apply for, or consent in writing to,
the appointment of a receiver, trustee or liquidator; (ii) file a voluntary
petition seeking relief under the Bankruptcy Code or be unable, or admit in
writing its inability, to pay its debts as they become due; or (iii) make a
general assignment for the benefit of creditors.

        SECTION 4.3.     Additional Covenants.

         (a)   HHH covenants that, on or before the Closing, he will cause all
of his liabilities to GGH which are secured by Liens on the Assets to be paid
in full.

         (b)   HHH further covenants (I) that he will create no consensual
Liens on any one or more of the Assets prior to Closing, except to secure a
lender or lenders for one or more new-money loans substantially all of the
proceeds of which are applied to pay in full the liabilities to GGH referred to
above ("bridge loan") and (II) that if he takes down a bridge loan and the same
is secured by Liens on any of the Assets, he will, at or before Closing cause
all liabilities to the holder or holders of the bridge loan which are secured
by Liens on the Assets to be paid in full.

         (c)   HHH hereby consents that if at Closing there exist any
consensual Liens created by HHH on any of the Assets other than those referred
to above and HHH fails to pay all good-faith uncontested liabilities secured by
all such Liens and if any of such liabilities not contested in good faith by
HHH to GGH or a holder or holders of a bridge loan shall not have been paid in
full by HHH, then HHH consents to Dart applying proceeds otherwise payable to
HHH to the extent necessary to pay down in





                                     - 34 -
<PAGE>   40
full all such then-unpaid liabilities not contested in good faith by HHH.

         (d)   Dart covenants that it will not attempt to apply or have applied
any amounts payable to HHH at Closing for use to eliminate the First Union Lien
for which HHH understands RSH has agreed with HHH that RSH will be responsible.


                                   ARTICLE V

                           COOPERATION; OTHER MATTERS

        SECTION 5.1.     Pending Litigation.  Within six (6) business days
after execution of the last to be executed of this Agreement, the Dart/Other
Hafts Agreement, the Dart/RSH First Supplemental Agreement and the Dart/RSH
Second Supplemental Agreement, counsel for Dart shall prepare and, subject to
approval thereof by counsel for HHH, file appropriate papers with the
appropriate courts to approve this Agreement and the transactions contemplated
hereby (these papers to be prepared at the sole cost and expense of Dart,
except that HHH will be responsible for his own legal fees in reviewing the
same).  At or promptly after the execution and delivery of this Agreement, Dart
and HHH shall cooperate in the preparation, delivery and filing of appropriate
pleadings and stipulations to stay, if possible, all Pending Litigation during
the period prior to the Closing or the termination of this Agreement.  Neither
party shall use the stay of any Pending Litigation pursuant to this Agreement
as a basis for arguing that the other party failed to prosecute or that such
party has been prejudiced by the lapse of time.  Dart and HHH shall cooperate
in the preparation, delivery and filing of appropriate papers with the
appropriate courts for the dismissal with prejudice of all Pending Litigation
except that Dart and HHH shall request that the lawsuit captioned Lou v.
Herbert H. Haft, et al., C.A. No. 13761 (Del. Ch. filed Sept. 23, 1994) be
dismissed without prejudice as against defendant Michael Klein and with
prejudice as against all other defendants.

        SECTION 5.2.     New Litigation.  Except for claims concerning
enforcement of this Agreement, neither party shall initiate any new litigation
claims against the other party prior to Closing or the termination of this
Agreement.  The parties agree that the





                                     - 35 -
<PAGE>   41
time periods prescribed in any statutes of limitations relevant to any claims
they may have against each other are tolled and shall not run from the date of
this Agreement until Closing or the termination of this Agreement.

        SECTION 5.3.     Cooperation and Support.  (a)  Subject to clause (d)
below, HHH and Dart shall each support the achievement of fulfillment of all
conditions precedent to Closing before the Bankruptcy Court and the Delaware
Court of Chancery and any other court or tribunal which shall be asked to
assert jurisdiction over the same.

        (b)  Subject to clause (d) below, Dart and HHH will each cooperate in
the defense of any litigation instituted by any Person challenging, and will
not challenge in any court proceeding this Agreement, the Dart/RSH Settlement
Agreement, the Dart/Other Hafts Agreement, the Dart/RSH First Supplemental
Agreement, the Dart/RSH Second Supplemental Agreement or any of the
transactions contemplated thereby provided, that all legal fees and costs
incurred in such defense of Dart's counsel and expert witnesses, if any, (other
than for HHH's and RSH's personal counsel) shall be paid by Dart.  Effective
upon execution and delivery of this Agreement by both HHH and Dart, HHH agrees
not to object, and effective upon such execution and delivery HHH consents, to
any settlement among Dart, Crown, Trak, Dart/SFW Corp., SFW Holding Corp., SFW,
RMH, GGH and LGH provided, however that nothing in the foregoing consent
requires HHH to enter into any agreement or incur any liability or obligation.
If any challenges to the transactions contemplated hereby are made after the
Closing, HHH's sole rights in respect thereof shall be governed by his
indemnification rights provided for in SECTION 2.1(c) above.

        (c)  Subject to clause (d) below, HHH hereby agrees to cooperate, in
his individual capacity and in his capacities as a stockholder, director,
officer and employee of Dart, with Dart in the full implementation of the
transactions contemplated by this Agreement, the Dart/RSH Settlement Agreement,
the Dart/RSH First Supplemental Agreement, the Dart/RSH Second Supplemental
Agreement and the Dart/Other Hafts Agreement and the financing thereof.

        (d)  Nothing in this SECTION 5.3 shall require HHH or Dart to waive
any attorney-client privilege.  Nothing in this SECTION 5.3





                                     - 36 -
<PAGE>   42
shall require HHH to take any action in his capacity as a director of Dart or
any Dart Affiliate that HHH determines to be inconsistent with the exercise of
his independent judgment as a fiduciary.  HHH shall not be required by this
SECTION 5.3 to take or not take any action individually or as a stockholder,
director, officer or employee of Dart if he reasonably determines, based on
written advice of counsel experienced in corporate law, that such action or
inaction would violate any duties imposed on him by law.

          (e)  In addition, subject to clause (d) above, HHH will cooperate
fully and promptly (including voting in favor of) and not interfere with the
confirmation and consummation of the Other Plans of Reorganization, provided
that no transfers of cash or other consideration thereunder may be payable to
or for the account of RSH or any one or more CPI Debtors unless and until the
Closing shall have occurred.

          (f)  Each of Dart and HHH shall use reasonable efforts to fulfill all
conditions to closing that are within the power of such party to fulfill;
provided, however, that this SECTION 5.3(f) shall not require Dart or HHH to
waive any conditions to closing and shall not require Dart or HHH to make any
payments or incur any costs not expressly required by this Agreement.
Notwithstanding the foregoing, neither this SECTION 5.3(f) nor any other
provision of this Agreement shall require Dart to agree to any terms, waive any
conditions or fail to perform any of its obligations with respect to the
Dart/Other Hafts Agreement, the Dart/RSH First Supplemental Agreement or the
Dart/RSH Second Supplemental Agreement, it being specifically acknowledged that
the Dart/Other Hafts Agreement may require Dart to close the transactions
pursuant thereto on a date prior to the Closing Date and whether or not the
Closing will occur.

          (g)  Subject to clause (d) above, HHH shall cooperate fully and
promptly and not interfere with the amended plans of reorganization for the
75th Avenue/Wooded Lot and Bridgeview Warehouses approved by RSH and Dart,
which may become effective prior to the Closing.

          (h)  Subject to clause (d) above, from and after the date of this
Agreement, HHH will agree not to object to or interfere in any way with, and
will agree to provide any consents that may be reasonably requested by Dart in
connection with any financing,





                                     - 37 -
<PAGE>   43
stock sale, asset sale or other similar transactions by Dart and/or any of its
subsidiaries after approval by a majority of the members of the Board of
Directors of Dart, SFW, Trak or Crown.

          (i)  Subject to clause (d) above, if and to the extent that clauses
(g) and (h) of this SECTION 5.3 are deemed to be inconsistent with any other
clause of this SECTION 5.3, clauses (g) and (h) shall take precedence.

          SECTION 5.4.     Further Assurances.  HHH and Dart each shall execute
and deliver, or shall cause to be executed and delivered, promptly such
additional documents, assignments, certificates and instruments as the other
party to this Agreement may reasonably request in order to effectuate more
effectively the transactions contemplated by the Settlement Documents.

          SECTION 5.5.     Liquidation Distributions.  In the event that after
the Closing the Board of Directors of Dart, after adopting a plan of complete
liquidation or after dissolution of Dart has been authorized in accordance with
Section 275 of the Delaware General Corporation Law (or any successor or
comparable statutory provision then applicable), may determine to pay a
liquidating distribution to the shareholders of Dart, then Dart may elect to
cap any and all actual and contingent liabilities that it or any Dart
Affiliates or any of their respective affiliates may have to HHH by the
establishment of a reserve fund for such purpose in the aggregate amount of
$1,000,000, it being understood that any unused portion of such reserve fund
may be withdrawn by or on behalf of Dart (or any liquidating trustee for Dart)
or distributed to Dart's stockholders at any time after December 31, 2002;
provided, that establishment of the reserve fund shall not cap any obligations
under the promissory note issued by Dart pursuant to SECTION 2.2(b)(i)(B) AND
(C) of this Agreement and any indemnification obligations for claims that are
pending, or are threatened or asserted in writing, and of which Dart has
written notice before the reserve fund is established.

                                INDEMNIFICATION

        SECTION 6.1.     Indemnification by HHH.  HHH shall defend, indemnify
and hold Dart, each of its subsidiaries and each of their respective officers,
employees, directors, agents and representatives (the "Dart Indemnitees")
harmless from and against any and all demands, claims, actions, suits,
proceedings, losses, damages, judgments, liabilities, costs and expenses,
including, without limitation, fees and expenses of legal counsel
(collectively, "Costs"), asserted against or incurred by any Dart Indemnitee,
directly or indirectly, arising out of or resulting from any inaccuracy in or
breach of any of the representations, warranties or covenants in any material
respect of HHH contained in any of the Settlement Documents, or any certificate
or other instrument furnished to any Dart Indemnitee by or on behalf of HHH
pursuant to any of the Settlement Documents.

        SECTION 6.2.     Indemnification by Dart.  Dart shall defend, indemnify
and hold HHH and his agents and representatives (the "HHH Indemnitees")
harmless from and against any and all Costs asserted against or incurred by any
HHH Indemnitee, directly or indirectly, arising out of or resulting from any
inaccuracy in or breach of any of the representations, warranties or covenants
in any material respect of Dart contained in any of the Settlement Documents,
or any certificate or other instrument furnished to any HHH Indemnitee by or on
behalf of Dart pursuant to any of the Settlement Documents.

        SECTION 6.3.     Indemnification Procedure.  As soon as is reasonably
practicable after any HHH Indemnitee or any Dart Indemnitee becomes aware of
any claim that it has to recover Costs under this ARTICLE 6, such HHH
Indemnitee or Dart Indemnitee, as the case may be ("Indemnified Party"), shall
notify the other party ("Indemnifying Party") in writing, which notice shall
describe the claim in reasonable detail, and shall indicate the amount
(estimated, if necessary and to the extent feasible) of the claim.  The failure
of any Indemnified Party to promptly give any Indemnifying Party such notice
shall not preclude such Indemnified Party from obtaining indemnification under
this ARTICLE 6, except to the extent that such Indemnified Party's failure has
materially prejudiced the Indemnifying Party's rights or materially increased
its liabilities and

obligations hereunder.  In the event of a third-party claim which is subject to
indemnification under this ARTICLE 6, the Indemnifying Party shall have the
right, upon agreeing in writing that it is obligated to fully indemnify the
Indemnified Party for the full amount of the claim (to the extent such claim is
proven or settled) and providing satisfactory evidence to the Indemnified Party
that the Indemnifying Party has sufficient financial resources to provide such
indemnification and defend such claim properly, to assume the defense of such
claim by counsel of its own choosing.  The Indemnified Party and the
Indemnifying Party shall cooperate with one another in the defense of such
claim, including the settlement of the matter on the basis stipulated by the
Indemnifying Party (with the Indemnifying Party being responsible for all costs
and expenses of such settlement).  If the Indemnifying Party within a
reasonable time after notice of a claim fails to defend the Indemnified Party,
the Indemnified Party shall be entitled to undertake the defense, compromise or
settlement of such claim at the expense of and for the account and risk of the
Indemnifying Party.

        SECTION 6.4.     Remedies to be Cumulative.  The remedies to any
Indemnified Party provided herein shall be in addition to, and not in lieu of
any other remedies to which such Indemnified Party is entitled at law or in
equity for any breach or non-compliance by any Indemnifying Party with the
provisions of any of the Settlement Documents, provided, however, that no claim
by a Dart Indemnitee shall constitute a defense to or set off against any
payment obligation of Dart under the June Note unless the same shall be based
solely on wrongful conduct by HHH after the Closing Date.

                                  ARTICLE VII

                                 MISCELLANEOUS

        SECTION 7.1.     Payments.  All payments to either party under this
Agreement shall be made on the date when due in immediately available funds to
such party's account, or such other account, as such party shall theretofore
have specified in accordance with the provisions of SECTION 7.4.

        SECTION 7.2.     Expenses.  Except as otherwise expressly provided for

with this Agreement and the transactions hereunder, including, without
limitation, any sales, transfer or other similar taxes and fees for accountants
and attorneys; provided, however, that any transfer or recordation taxes
payable in connection with the transfer by HHH of his interest in the Warehouse
Interest known as Pennsy I will be paid 50% by HHH and 50% by Dart.

        SECTION 7.3.     Drafting Party.  Each party stipulates that it has
been represented in the negotiations for and the preparation of this Agreement
by counsel of their own choosing; that they have read the Agreement or have had
it read to them by their counsel; that they have had it fully explained to them
by their counsel; and that they are fully aware of its contents and of its
legal effect.  Accordingly, HHH and Dart agree that the rule that the language
of this Agreement be interpreted against the drafting party shall not apply.

        SECTION 7.5.     Amendment and Waivers.  This Agreement may be amended
or supplemented only by a written instrument duly executed by or on behalf of
each party hereto.  Any term or condition of this Agreement may be waived at
any time by the party that is entitled to the benefit thereof, but no such
waiver shall be effective unless set forth in a written instrument duly
executed by or on behalf of the party waiving such term or condition.  No
waiver by either HHH or Dart of such party's rights under any provision of this
Agreement shall constitute a waiver of such party's rights under such provision
at any other time or the waiver of such party's rights under any other
provision of this Agreement.  No failure or delay by HHH or Dart in exercising
any right, power or privilege hereunder shall operate as a waiver thereof nor

        SECTION 7.6.     Severability.  If any one or more provisions of this
Agreement or any agreement, document or instrument delivered pursuant hereto
(including without limitation the Mutual Releases in the form of EXHIBIT 14)
shall be declared invalid, illegal or unenforceable in whole, in part or in any
respect, the validity, legality and enforceability of all remaining provisions
shall not in any way be affected or impaired.

        SECTION 7.7.     Survival of Representations and Warranties.  The
representations and warranties and covenants of the parties hereto shall
survive the Closing Date.

        SECTION 7.8.     Governing Law.  This Agreement and the documents and
instruments delivered pursuant hereto (except as otherwise provided therein)
shall be governed by and construed in accordance with the laws of the State of
Delaware.

        SECTION 7.9.     Counterparts.  This Agreement may be signed in
counterparts, each of which shall be an original, with the same effect as if
the signatures thereto and hereto were upon the same instrument.  This
Agreement constitutes the entire agreement and understanding among the parties

acknowledge and agree that in the event of any breach of this Agreement or any
other Settlement Document, the non-breaching party would be irreparably harmed
and could not be made whole by monetary damages.  It is accordingly agreed that
HHH and Dart, in addition to any other remedy to which they may be entitled to
at law or in equity, shall be entitled to compel specific performance
(including by temporary restraining orders) of this Agreement or any other
Settlement Document in any action instituted in the Delaware Court of Chancery
or the United States District Court for the District of Delaware, or, in the
event neither of said courts could have jurisdiction over such action,





                                     - 43 -
<PAGE>   49
in any court of the United States or any state having subject matter
jurisdiction.

          (b)  If this Agreement terminates without the Closing having
occurred, neither party shall have any liability for damages arising out of
this Agreement except for actual damages directly caused by such party's breach
of its express obligations set forth in this Agreement.

          (c)  HHH and Dart consent to personal jurisdiction in any such action
brought in the Delaware Court of Chancery or the United States District Court
for the District of Delaware.

        SECTION 7.12.    Termination.  (a) Either party may terminate this
Agreement at any time prior to Closing by written notice to the other if at the
time such notice is delivered to any of the Dart/Other Hafts Settlement
Agreement, the Dart/RSH First Supplemental Agreement or the Dart/RSH Second
Supplemental Agreement shall have been terminated or become unenforceable.

         (b)   Either party may terminate this Agreement at any time prior to
Closing by written notice to the other:  (i) if the other party shall have
failed in any material way to perform its obligations under this Agreement and
shall have failed to cure such failure within ten (10) days after written
notice thereof from the other party; (ii) if the Dart/Other Hafts Settlement
Agreement, the Dart/RSH First Supplemental Agreement or the Dart/RSH Second
Supplemental Agreement shall have terminated without closing otherwise than by
reason of default by Dart or any Dart Affiliate; (iii) if the conditions
precedent set forth in Sections 3.3(a) and 3.3(b) and SECTIONS 3.4(a) AND
3.4(b) shall not have been fulfilled on or before June 15, 1998; (iv) if all of
the express conditions to such party's obligation to close set forth in
SECTIONS 3.3 OR 3.4, as the case may be, shall not have been satisfied by June
30, 1998; provided, however, that if the Delaware Court of Chancery shall have
issued a ruling on the application for approval of this Agreement or any
related matters, and any applications for rehearing, notices of appeal or other
similar proceedings with respect thereto have been made or filed
("post-judgment review") then each of the two deadline dates set forth above
shall automatically be extended until the fifteenth Business Day after the
entry of its order on the approval of this Agreement or final resolution of all
such post-judgment review, as the case may be, with the understanding that





                                     - 44 -
<PAGE>   50
each of the above dates, if so postponed, will each be postponed to the same
date as the other; or (v) if the Closing shall not have occurred by 11:59 p.m.
(EST) on December 31, 1998.

        SECTION 7.13.    Time.  Time is of the essence in this Agreement.

        SECTION 7.14.    Assignment.  Neither party may assign its rights
hereunder, except that Dart may assign any of its rights under this Agreement
to any Person, who at the time of such assignment, is a Dart Affiliate.  The
obligations under this Agreement shall not be the obligations of any Dart
Affiliate.

        SECTION 7.15.    Third Parties.  Nothing herein expressed or implied is
intended or shall be construed to confer upon or give any Person, other than
the parties hereto, any right or remedies under or by reason of this Agreement.

                                  ARTICLE VIII

        SECTION 8.1.     Limited Right of Dart to Terminate Agreement.  (a)
Notwithstanding any other provision of this Agreement, none of the
representations and warranties, covenants, agreements, obligations or
commitments of Dart set forth in this Agreement shall be effective if (i) after
Dart shall have given written notice of this Agreement pursuant to Section 8 of
the Standstill Order to the other Persons subject to the Standstill Order, any
of such Persons shall have timely filed any objection to this





                                     - 45 -
<PAGE>   51
        Agreement pursuant thereto and (ii) Dart, in good faith, determines
that there might be sufficient merit in such objection that it is in the best
interests for Dart to declare, by written notice to HHH, that it has elected to
invoke this clause (a) and declare this Agreement to have been null and void,
ab initio, whereupon, after the giving of such notice, this Agreement shall be
null and void, ab initio.

        (b) This Agreement shall be null, void and of no effect, ab initio, if
on or before the eighth (8th) Business Day after the date of execution and
delivery hereof by Dart, the Delaware Court of Chancery issues any order, writ,
injunction or decree restraining, enjoining or prohibiting in any way the
effectiveness of this Agreement or the consummation of any of the transactions
contemplated by this Agreement.

        SECTION 8.2.     HHH Bound.  All of the provisions of this Agreement
shall be binding on and effective with respect to HHH from the date stated in
the first sentence of this Agreement.  HHH hereby acknowledges that adequate
and valid consideration has been received for his agreement to be bound to all
of the provisions of this Agreement from this date, notwithstanding Dart's
right to elect not to be bound pursuant to SECTION 8.1.

executed on its behalf) this Agreement as of the date first above written.

other default, breach or violation. The rights or remedies herein expressly
specified are cumulative and not exclusive of any other rights and remedies

                    CONTRIBUTION AND SUBORDINATION AGREEMENT


         THIS CONTRIBUTION AND SUBORDINATION AGREEMENT (this "Agreement"), dated
__________ __, 1997, is made by and among, Dart Group Corporation, A Delaware
corporation ("Dart"), HHH/RSH Tier II Limited Partnership, a Maryland limited
partnership (the "Retained Partnership"), Ronald S. Haft (RSH"), Herbert H. Haft
("HHH"), the Releasing Guarantors listed on Schedule 1 hereto and the Released
Guarantors listed on Schedule 2 hereto.

                                    Recitals

A.       It is contemplated that Dart may make a $10 million loan (the "RSH/HHH
         Loan") pursuant to the RSH/HHH Loan Agreement (as such term is defined
         in the Settlement Agreement dated as of August 18, 1997, among Dart,
         certain Affiliates of Dart, Robert M. Haft, Gloria G. Haft and Linda G.
         Haft (the "Settlement Agreement")), repayment of which would be secured
         in party by, among other things, all of HHH and RSH's rights, title and
         interest in and to the Collateral (as defined in Section 2(a) of this
         Agreement) and the Retained Partnership.

B.       All of the parties to this Agreement, except Dart and the Retained
         Partnership, are parties to an Indemnification Agreement, dated as of
         July 31, 1994 (the "Indemnification Agreement"), under which HHH and
         RSH agreed to indemnify Robert M. Haft ("RMH"), Gloria G. Haft ("GGH")
         and Linda G. Haft ("LGH") and collectively "RGH") with respect to,
         among other things, "all claims . . . made or incurred by, or asserted
         against, any of [RGL]" in connection with all liabilities or
         obligations that RMH, LGH or GGH may have in connection with "all
         partnership, corporate and individually held interest of the Haft
         Family in that collection of entities, through which the Haft Family
         owns, operates or manages their privately held warehouses (the
         "Combined Entities") . . . ." The Combined Entities, which include
         guaranteed these indemnification obligations of HHH and RSH to RGL.
         Each of the Combined Entities has certain rights to seek contribution
         from the other Combined Entities in the event that it pays more than
         its share of any of the guaranteed indemnification obligations.

C.       If Dart makes the RSH/HHH Loan, the Retained Partnership, pursuant to
         the terms and provisions of that certain Retained Partnership Guaranty,
         will become a Guarantor under the Indemnification Agreement.


                                                1


<PAGE>   66
D.       Dart is unwilling to make the RSH/HHH Loan unless the Releasing
         Guarantors (1) release all rights of contribution they may have against
         the Released Guarantors, and (2) subordinate any claims they now have,
         or may hereafter have in the Collateral to the claims of Dart.

                                   Agreements

         NOW THEREAFTER, to induce Dart to enter into the RGL Settlement
Agreement, to enter into the RSH/HHH Loan Agreement and to make the loans
contemplated thereunder, the parties hereto hereby agree as follows:

         1. Release of Released Guarantors. Each of the Releasing guarantors
irrevocably and unconditionally hereby releases each of the Released Guarantors
from any and all manner of claims, demands, damages, actions, causes of action,
contracts, agreements, charges, sums of money, claims for attorney's fees and
lawsuits of every kind and description whatsoever, in law or equity, whether
known or unknown, for contribution, or otherwise (a "Claim") under, or in
connection with, the Indemnification Agreement, that certain Settlement
Agreement dated as of August __, 1997 between RSH and HHH, and any other
agreements pursuant to which any of the Released Guarantors are jointly,
severally, or jointly and severally liable in any respect to HHH, RSH, RMH, GGH,
LGH or any entity directly or indirectly controlled by one or more of such
persons.

         2. Subordination of Claims.

            (a) Subordination of Claims. Any Claim, however arising, which any
Releasing Guarantor may now or hereafter have in or against or with respect to
any of the Collateral shall be subject, junior and subordinate to any Claim that
Dart or any affiliate of Dart now or hereafter has against the Guarantors for,
or with respect to any Collateral for, the obligations owing to Dart under the
RSH/HHH Loan and to any unsecured Claim or Dart or any affiliate of Dart against
any Guarantor or the Retained Partnership to the extent that Dart or such
affiliate has any secured or unsecured Claims arising in connection with or
relating to the RSH/HHH Loan. The term "Collateral" shall mean: (i) all general
and limited partnership interest or shares in Combined Property/Forbes Limited
Partnership, CP/Forbes Boulevard, Inc., Haft/Equities-Sully Plaza Limited
Partnership, Combined Property/Ontario Limited Partnership and 3301 Pennsy Drive
Associates Limited Partnership (collectively, the "Collateral Entities"); and
(ii) all property of and interests in the property of the Collateral Entities
and of the Retained Partnership, whenever acquired and wherever located, that is
collateral security for the indebtedness to Dart arising under the RSH/HHH Loan,
including, without limitation, any direct or indirect interests in the Rolling
Valley, Maryland 


                                        2


<PAGE>   67
City and Sully shopping centers and the 4600 Forbes Boulevard office building
(but excluding any other property or interest of RSH, HHH or of the Releasing
guarantors that may hereafter be acquired by any of the Collateral Entities or
the Retained Partnership, if and to the extent such acquisition was for less
than fair value.

            (b) Extent of Subordination. The subordinations and priorities
specified herein are applicable irrespective of the time, manner or order of
attachment or perfection of any security interest in the Collateral, or the time
or order of filing of any financing statements, or the giving or failure to give
notice of the acquisition or expected acquisition of any purchase money security
interest or other security interest. Such subordinations and priorities shall
remain effective notwithstanding the amendment or modification of the documents
governing the FSH/HHH Loan or governing the grant of any security interest in
the Collateral to secure repayment of the indebtedness arising under the RSH/HHH
Loan or the commencement of a case by or against either Dart of any obligor
under the RSH/HHH Loan under Title 11 of the United States Code or any similar
insolvency or moratorium laws; except that such subordination shall not be
effective to the extent that Dart hereafter increases the principal amount owing
under the RSH/HHH Loan or extends the maturity date thereof.

            (c) Standstill. Until all of the obligations owed to Dart, or any
affiliate of Dart, under the HHH/RSH Loan have been paid in full, no Releasing
Guarantor shall accept any payment from the Retained Partnership or any entity
constituting (or the partnership interest in which, or capital stock of which,
constitute) a part of the Collateral. Each Releasing Guarantor agrees to refrain
from taking any action against the Collateral unless it shall have obtained
Dart's prior written consent or Dart shall have been repaid in full for all
amounts owing under the RSH/HHH Loan. No Releasing Guarantor shall obtain or
take any action to obtain any judgment under which it could attach or seize any
of the Collateral in any way until Dart shall have been repaid in full for all
amounts owing under the RSH/HHH Loan. If, prior to the repayment in full of the
RSH/HHH Loan, an RGH Release Party has been granted or otherwise obtains
possession of Collateral then, in addition to any obligations or remedies
imposed or provided under the Uniform Commercial Code (the "UCC") or other
applicable law, the RGL Release Parties shall hold such Collateral, any right,
title or interest therein and any proceeds thereof in trust for the Dart
Companies (the "Trust Property"), and turn over such Trust Property to the Dart
Companies as soon as practicable.

            (d) Rights on Default. Each Releasing Guarantor acknowledges that
Dart has and is entitled to exercise all of the rights and remedies of a secured
creditor under the UCC with respect to the Collateral, 


                                        3


<PAGE>   68
including, without limitation, the right to take possession of and dispose of
the Collateral after an event of default, and to accept the Collateral as
discharge of the obligations under the RSH/HHH Loan to the extent permitted
under the UCC. If Dart were to elect to sell the Collateral in a public or
private sale, conducted in accordance with the UCC, any purchaser of all or any
part of the Collateral shall take such Collateral free and clear of all rights
and interests of any of the Releasing Guarantors (including, without limitation,
any rights or interests of any of the RGL Releasing Guarantors in the property
or assets of any of the Collateral Partnerships(, and the Releasing Guarantors
shall have such rights and interests in and to the proceeds of any such sale,
after payment in full of all obligations owed to Dart or any affiliate of Dart
under the HHH/RSH Loan, as may be provided under the UCC.

         3. No Challenge to Dart Company Rights in the Collateral.

         No Releasing Guarantor shall challenge the attachment, validity,
perfection, priority or extent of any Claim of Dart or any affiliate of Dart in
the Collateral or with respect to the Retained Partnership in any judicial,
administrative or alternative dispute resolution proceeding.

         4. Waivers.

         No delay on the part of a party hereto in exercising any right, power
or privilege granted hereunder shall operate as a waiver thereof, and no
purported waiver of any default, breach or violation of any term or provision
contained herein shall be deemed to be a waiver of such term or provision unless
the waiver is in writing and signed by the waiving party. No such waiver shall
in any event be deemed a waiver of any subsequent or other default, breach or
violation. The rights or remedies herein expressly specified are cumulative and
not exclusive of any other rights and remedies which the parties would otherwise
have.

         5. Severability; Enforceability.

         In case any provision of this Agreement shall be held to be illegal,
invalid or unenforceable under present or future laws effective while this
Agreement remains in effect, the legality, validity and enforceability of the
remaining provisions will not in any way be affected or impaired thereby.

         6. Governing Law.

         This Agreement will be governed by and construed in accordance with the
laws of the Commonwealth of Virginia, without regard to its principles
concerning conflicts of law, and any actions under this Agreement may be 


                                        4


<PAGE>   69
brought in the courts of the Commonwealth of Virginia or the United States
District Court for the Eastern District of Virginia.

         7. Different Facts.

         Each Releasing guarantor specifically acknowledges that the facts with
respect to which this Agreement is executed may turn out to be other than or
different from the facts now known to or believed by it to be true, and that it
therefore expressly assumes the risk of the facts turning out to be different
and agrees that this Agreement shall be in all respects effective and not
subject to termination or rescission by reason of any different facts.

         8. Notices.

         Notices given in connection with this Agreement shall be in writing and

         attorneys' fees and court costs.

         All such obligations, sums and expenses set forth in clauses (a) and

Schedule A.

         SECTION 3.  Pledge.

         3.1.  Pledge.  To secure the Secured Obligations and for the purposes

               (b)  all cash, securities, interest, dividends, distributions,
         rights and other property at any time and from time to time received,
         receivable or otherwise distributed in respect of or in exchange for 
         any or all of the Pledged Stock; and

               (c)  to the extent not otherwise included, all proceeds of any

<PAGE>   86

Secured Party to have a good, valid and perfected first lien on, pledge of and
security interest in the Pledged Stock.

         (b)     Upon the occurrence and during the continuance of an Event of
Default, any or all of the shares of the Pledged Stock may, at the option of
the Secured Party, be registered in the name of the Secured Party or in the

demand of the Secured Party, Pledgor shall cause the Issuer to effect such
registration.

         3.3.    Substitution.  At the option of Pledgor, Pledgor may at any
time deliver to the Secured Party a letter of credit in the face amount equal

and (b) holding and applying any other Collateral in accordance with the terms
of this Agreement.  The agreement by which the Agent agrees to serve in such

         SECTION 5.  Voting Rights, Dividends and Distributions.

         5.1.  Voting Rights.  Prior to (a) the occurrence of an Event of
Default and (b) the lapse of ten days thereafter, Pledgor shall be entitled to

<PAGE>   87
voting and other consensual rights and powers pertaining to the Pledged Stock
or any part thereof and the other Collateral; provided, however, that no vote
shall be cast or any consent, waiver or ratification given or any action taken
which would violate (or cause Pledgor to violate) any of the terms of this
Agreement.  After the occurrence of an Event of Default, Pledgee shall be the
sole Person entitled to vote.

         5.2.  No Dividends or Distributions.  All dividends and distributions
made on or in respect of the Pledged Stock, and any and all cash and other
property received in exchange for or redemption of any of the Pledged Stock,
shall be delivered to Agent to be held and applied, as part of the Collateral,
as set forth in this Agreement.

         SECTION 6.  Remedies on Default.

         6.1.  Sale of Collateral.

         (a)   If at any time an Event of Default shall have occurred and be
continuing and shall have resulted in acceleration of the maturity of the
Secured Obligations, then, in addition to having all of the rights of a secured
party upon default under the Uniform Commercial Code as then in effect in any
applicable jurisdiction (the "UCC"), the Secured Party may, to the extent
permitted by law, without being required to give any notice to Pledgor except
as expressly provided below:

                (i)       apply any cash held by the Secured Party hereunder in
         the manner provided in Section 6.2 below; and

                (ii)      if there shall be no such cash or if the cash so
         applied shall be insufficient to pay in full the items specified
         in such Section 6.2, collect, receive, appropriate and realize
         upon the Collateral or any part thereof, and sell, assign,
         contract to sell or otherwise dispose of and deliver the
         Collateral or any part thereof, in one or more portions, at public
         or private sale or at any broker's board, on any securities
         exchange or elsewhere, for cash, upon credit or for future
         delivery, and at such price or prices as the Secured Party may
         reasonably deem best, and, subject to Section 6.1(h) hereof, the
         Secured Party may (except as otherwise provided by law) be the
         purchaser of any or all of the Collateral so sold and thereafter
         may hold the same, absolutely, free from any right or claim of
         whatsoever kind.

         (b)  In the event of a sale of the Pledged Stock as aforesaid, the
Secured Party is authorized, at any such sale, if the Secured Party deems it
advisable so to do in order that such sale may be effected in such manner as to
comply with all applicable state and federal securities laws, to restrict the
number of prospective





                                       4
<PAGE>   88
bidders or purchasers and/or further restrict such prospective bidders or
purchasers to persons who will represent and agree that they are purchasing for
their own account, for investment, and not with a view to the distribution or
resale of the Pledged Stock, and may otherwise require that such sale be
conducted subject to restrictions as to such other matters as the Secured Party
may reasonably deem necessary in order that such sale may be effected in such
manner as to comply with all applicable state and federal securities laws.
Upon any such sale, the Secured Party shall have the right to deliver, assign
and transfer to the purchaser thereof the Pledged Stock so sold.

          (c)  Pledgor hereby acknowledges that, notwithstanding that a higher
price might be obtained for the Pledged Stock at a public sale than at a
private sale or sales, the making of a public sale of the Pledged Stock may be
subject to registration requirements under federal and state securities laws
and similar other legal restrictions compliance with which would require such
actions on the part of Pledgor, would entail such expenses, and would subject
the Secured Party, any underwriter through whom the Pledged Stock may be sold
and any controlling person of any thereof to such liabilities, as would make a
public sale or the Pledged Stock impractical.  Accordingly, Pledgor hereby
acknowledges that (i) private sales of the Pledged Stock made by the Secured
Party in accordance with the provisions of this Section 6.1 may be at prices
and on other terms less favorable to the seller than if the Pledged Stock were
sold at public sale; and (ii) the Secured Party shall have no obligation to
take any steps in order to permit the Pledged Stock to be sold at a public
sale.

          (d)  Each purchaser or Collateral at any such sale made in accordance
with the provisions of this Section 6.1 shall hold the property sold,
absolutely, free from any claim or right of whatsoever kind, including any
equity or right of redemption of Pledgor.  Upon any sale of Collateral by the
Secured Party made in accordance with the provisions of this Section 6.1
(whether by virtue of the power or sale herein granted, pursuant to judicial
process or otherwise), the receipt of the Secured Party or any agent thereof
making the sale shall be a sufficient discharge to the purchaser or purchasers
of the Collateral so sold, and such purchaser or purchasers shall not be
obligated to see to the application of any part of the purchase money paid over
to the Secured Party or agent or be answerable in any way for the
misapplication or nonapplication thereof.  The Secured Party shall give Pledgor
not less than ten (10) days' prior written notice of the Secured Party's
intention to make any public or private sale of Collateral and Pledgor shall
have the right, during the period following receipt of such notice until the
date of any public sale specified in such notice, or in the case of any private
sale, until such time as the Secured Party shall have entered into an agreement
for the sale of Collateral (or any portion thereof), to redeem the Collateral
by payment in full of the Secured Obligations and all amounts described in
Section 6.2(a) hereof.  Such notice, in case of public sale, shall state the
time and place fixed for such sale,





                                       5
<PAGE>   89
and, in case of sale at broker's board, on a securities exchange, or elsewhere,
shall state the board, exchange or other location at which such sale is to be
made and the day on which the Collateral, or that portion thereof so being
sold, will first be offered for sale at such location, and such notice shall be
deemed to be reasonable notification of such matters.

          (e)  Any public sale of Collateral shall be held at such time or
times within the ordinary business hours and at such place or places as the
Secured Party may fix in the notice of such sale.  Any sale of the Collateral
held by the Secured Party may be sold in one lot as an entirety or in parts, as
the Secured Party may determine.  The Secured Party shall not be obligated to
make any sale pursuant to any such notice.  The Secured Party may, without
notice or publication, adjourn any sale or cause the same to be adjourned from
time to time by announcement at the time and place fixed for the sale, and such
sale may be made at any time or place to which the same may be so adjourned.
In case of any sale of all or any part of the Collateral on credit or for
future delivery, the Collateral so sold may be retained by the Secured Party
until the selling price is paid by the purchaser thereof, but the Secured Party
shall not incur any liability in case of the failure of such purchaser to take
up and pay for the Collateral so sold and, in case of any such failure, such
Collateral may again be sold upon like notice.

          (f)  The Secured Party, instead of exercising the power of sale
herein conferred upon him, may proceed by a suit or suits at law or in equity
to foreclose this Agreement and sell the Collateral held by the Secured Party,
or any portion thereof, under a judgment or decree of court or courts of
competent jurisdiction.

          (g)  On any sale of the Collateral, the Secured Party is hereby
authorized to comply with any limitation or restriction in connection with such
sale that the Secured Party may be advised by counsel in writing is necessary
in order to avoid any violation of applicable law or in order to obtain any
required approval of the purchaser or purchasers by any Governmental Authority
or officer or court.

          (h)  Notwithstanding anything contained herein to the contrary, the
Secured Party hereby agrees (i) not to purchase the Collateral if a third party
has made an offer to purchase the Collateral at a price which would repay in
full the Secured Obligations and all amounts described in Section 6.2(a) hereof
and (ii) that if the Secured Party does purchase the Collateral, he will sell,
transfer or otherwise dispose of the Pledged Stock within six (6) months after
the date of acquisition thereof.

          (i)  If an Event of Default shall have occurred and be continuing,
Dart will, at the Secured Party's request, use its reasonable efforts to file a
registration statement the form of which is, under the rules and regulations of
the Securities





                                       6
<PAGE>   90
and Exchange Commission, suitable for effecting a public offering in which
stock constituting any part of the Collateral (hereafter "Stock Collateral")
shall be offered for sale and to cause such registration statement to become
effective within 120 days after the filing of such registration statement.  In
connection with such registration of the Stock Collateral:

                (i)       Dart shall indemnify and hold harmless each Secured
         Party and any underwriter (as defined in the Securities Act of
         1933, as amended (the "Act")) for such Secured Party from and
         against any and all losses, damages, liabilities, claims, costs or
         expenses (each a "Loss" and collectively "Losses"), to which such
         Secured Party or any such underwriter becomes subject under the
         Act or otherwise, insofar as such Losses are caused by any untrue
         statement of any material fact contained in such registration
         statement, any prospectus contained therein or any amendment or
         supplement thereto, or arise out of or are based upon the omission
         to state therein a material fact required to be stated therein or
         necessary to make the statements therein, in light of the
         circumstances in which they were made, not misleading; provided,
         however, that Dart will not be liable in any such case to the
         extent that any such Losses arise out of or are based upon (A) an
         untrue statement or omission made in conformity with information
         furnished by the Secured Party seeking indemnification in writing
         specifically for use in the preparation of a registration
         statement or (B) a Secured Party's failure to deliver a copy of
         the registration statement, prospectus or any amendments or
         supplements thereto; and
         
               (ii)       Each Secured Party shall indemnify and hold harmless
         Dart, its officers, directors and agents, each other Secured
         Party, and any underwriter, from and against any and all Losses to
         which such indemnified person or entity becomes subject under the
         Act or otherwise which are caused by any untrue statement of any
         material fact contained in such registration statement, any
         prospectus contained therein, or any amendment or supplement
         thereto, or arise out of or are based upon the omission to state
         therein a material fact required to be stated therein or necessary
         to make the statements therein, in light of the circumstances in
         which they were made, not misleading, in each case to the extent
         that such untrue statement or omission was so made in reliance
         upon written information furnished by such indemnifying Secured
         Party for use in the preparation of such registration statement.

6.2      Application of Proceeds.  The proceeds of any collection, recovery,
receipt, appropriation, realization or sale of the Collateral as aforesaid
shall be applied as follows:





                                       7
<PAGE>   91
               (a)        First, to the payment of all reasonable costs and
         expenses of every kind incurred by the Secured Party in connection
         therewith or incidental to the care, safekeeping or otherwise of
         any of the Collateral required to be paid by Pledgor hereunder,
         including, without limitation, reasonable attorneys' fees and
         expenses;
         
               (b)        Second, to the payment to the Secured Party in
         satisfaction of the Secured Obligations owed to the Secured Party;
         and
         
               (c)        Third, to the payment of any surplus then remaining
         from such proceeds to Pledgor, unless otherwise required by law or
         directed by a court of competent jurisdiction;

provided, however, that Pledgor shall be liable for any deficiency if such
proceeds are insufficient to satisfy all of the Secured Obligations.

         SECTION 7.  Remedies Cumulative.

         Each right, power and remedy of the Secured Party provided for in this
Agreement or the Secured Notes or now or hereafter existing at law or in equity
or by statute shall be cumulative and concurrent and shall be in addition to
every other such right, power or remedy.  The exercise or beginning of the
exercise by the Secured Party of any one or more of the rights, powers or
remedies provided for in this Agreement or the Secured Notes or now or
hereafter existing at law or in equity or by statute or otherwise shall not
preclude the simultaneous or later exercise by the Secured Party of all such
other rights, powers and remedies, and no failure or delay on the part of the
Secured Party to exercise any such right, power or remedy shall operate as a
waiver thereof.

         SECTION 8.  Duties of the Secured Party.

         The rights conferred on the Secured Party hereunder are solely to
protect the Secured Party's interest in the Collateral as security for the
Secured Obligations and shall not impose any duty upon the Secured Party to
exercise any such rights.  The Secured Party shall not have any duty as to any
Collateral or as to the taking of any necessary steps to preserve rights
against prior parties or any other rights pertaining to any of the Collateral,
except that with respect to the custody, safekeeping and physical preservation
of any Collateral in the Secured Party's possession, under Section 9-207 of the
UCC or otherwise, the sole duty of the Secured Party shall be to deal with it
in the same manner as the Secured Party deals with similar securities and
property for the Secured Party's own account.  To the fullest extent permitted
by law, the Secured Party shall not be liable for failure to demand, collect or
realize upon any of the Collateral or for any delay in doing so and shall not
be under any obligation to sell or otherwise dispose of any





                                       8
<PAGE>   92
Collateral upon the request of Pledgor or otherwise.  The Secured Party shall
be accountable only for amounts that the Secured Party actually receives as a
result of the exercise of such powers, and the Secured Party shall not be
responsible to Pledgor for any act or failure to act with respect to the
Collateral, other than the Secured Party's negligence or willful misconduct.

         SECTION 9.  Further Assurances.

         Pledgor agrees that it will join with the Secured Party in executing
and will file and refile under the UCC such financing statements, continuation
statements and other documents in such offices as the Secured Party may
reasonably deem necessary or appropriate and wherever required or permitted by
law in order to perfect and preserve the security interest in the Collateral
created hereunder, and hereby authorizes the Secured Party to file financing
statements and amendments thereto relative to all or any part of the Collateral
without the signature of Pledgor where permitted by law, and agrees to do such
further acts and things and to execute and deliver to the Secured Party such
additional conveyances, assignments, agreements and instruments as such person
may reasonably require or deem advisable to effectuate the purposes of this
Agreement or to further assure and confirm unto the Secured Party his rights,
powers and remedies hereunder.

         SECTION 10.  Termination; Release.

         Upon the Termination Date (as defined below), this Agreement shall
terminate and (a)  the Agent, at the request of Pledgor, shall promptly deliver
to Pledgor all of the Collateral (including, without limitation, the Pledged
Stock) then in the possession of the Agent, and (b) the Secured Party, at the
request of Pledgor, shall promptly execute and deliver to Pledgor a proper
instrument or instruments acknowledging the satisfaction and termination of
this Agreement, and will duly assign, transfer and deliver to Pledgor (without
recourse and without any representation or warranty) such of the Collateral as
may be in the possession of the Secured Party and as has not theretofore been
sold or otherwise applied or released pursuant to this Agreement.  As used in
this Agreement, the term "TERMINATION DATE" shall mean the date upon which the
Secured Notes are paid in full and all other Secured Obligations, if any, then
owing shall have been paid in full.

         SECTION 11.  Notices.

                                 PLEDGED STOCK

  A.  Initial Pledged Stock.  The Pledged Stock securing the obligations of the
      Pledgor to Secured Party shall initially consist of certain of the
      outstanding and issued common stock of Pledgor and Trak Auto Corporation,
      a Delaware corporation ("TRAK") (or if Dart shall have sold any part of
      Trak, then SFW Holding Corp. ("SFWH"), which Pledged Stock is owned by
      Pledgor, as follows:

      Pledged Stock                                                  Issuer

      1.  $20,000,000 worth of shares of common stock of              Trak

          regulations); and

      2.  122,247 shares of Class A Common Stock of                  Pledgor
          Pledgor.                                                         

  B.  Adjustments to Pledged Stock.  On the first business day of each month
      following the date of the Agreement until the Secured Notes are paid in
      full (each such date being a "DETERMINATION DATE"), Pledgor shall deliver
      by fax to Pledgee a written statement of Pledgor's determination of the
      Collateral Value (as defined below).  If (1) on any Determination Date
      the Collateral Value is not equal to the Required Collateral Valuation
      Amount (as defined below) and (2) HHH has not sent to Pledgor sooner than
      the fifth business day after such first business day a written objection
      as to Pledgor's determination of value, then on the sixth business day
      after such Determination date:

          (i)  if the Collateral Value is less than the Required Collateral
               Valuation Amount, Pledgor shall deliver to the Security
               Perfection Agent certificates evidencing such additional number
               of shares of common stock of Trak registered in the name of
               Pledgor (duly endorsed for transfer or accompanied by signed
               stock powers (in either case, with signatures guaranteed by
               Medallion Signature Guaranty)) as shall be necessary for the
               Collateral Value as of such Determination Date to equal the
               Required Collateral Valuation Amount; provided, however, that
               Pledgor shall not be obligated to deliver more than 3,962,246





<PAGE>   98
               shares of the common stock of Trak as collateral for any
               obligations of Pledgor to Secured Party whether arising under
               this Agreement, the Secured Notes, any other agreement or
               promissory note, or otherwise; and

         (ii)  if the Collateral Value as of any Determination Date is greater
               than the Required Collateral Valuation Amount, the Security
               Perfection Agent shall return to Pledgor certificates evidencing
               such number of shares of common stock of Trak (together with any
               endorsements or other stock powers as shall have been delivered
               in connection with such common stock by Pledgor) as shall be
               necessary for the Collateral Value as of such Determination Date
               to equal the Required Collateral Valuation Amount.

  C.  Certain Definitions.  For purposes of this Schedule A, the following
      terms shall have the meanings set forth below:

          (i)  "COLLATERAL VALUE" for any Determination Date shall be an amount
               equal to the sum of 100% of the aggregate value of the shares of
               common stock of Trak constituting a part of the Pledged Stock,
               determined by reference to the average of the closing bid/asked
               prices as reported on the NASDAQ (or any other national
               securities exchange) for the thirty (30) trading days
               immediately prior to such Determination Date; plus the value of
               any cash constituting a part of the Collateral.

         (ii)  "REQUIRED COLLATERAL VALUATION" means an amount equal to 200%
               (or such higher percentage, if any, as may at any time be
               required by applicable law or regulation) of the then aggregate
               principal amount outstanding under the Secured Note.

Larry Schafran, et al., Civ. A. No. 14620 (Del. Ch.), challenging certain of
the transactions pursuant to the RSH/Dart Settlement Agreement, contending that

directors selected by the RGL Individuals are the properly empowered directors
of Dart (the "Section 225 Lawsuit");

                 WHEREAS, on November 6, 1995 Herbert H. Haft ("HHH") filed a
lawsuit captioned Herbert H. Haft v. Dart Group Corporation, et al., Civ. A.
No. 14685 (Del. Ch.), challenging the transactions pursuant to the RSH/Dart
Settlement Agreement (the "HHH Settlement Lawsuit");

                 WHEREAS, in connection with the Section 225 Lawsuit and the
HHH Settlement Lawsuit, the Delaware Court of Chancery entered an order (the
"Standstill Order") on December 6, 1995 that requires Dart to refrain from
taking or recognizing specified actions and that, in Section 8 of the
Standstill Order, requires Dart to give not less than seven (7) days' notice of
certain "extraordinary transactions" to the other parties to such lawsuits;

                 WHEREAS, on or about August 18, 1997, Dart and the RGL

                 1.2       CLOSING PROCESS; CONDITIONS; INTERRELATIONSHIP OF
                           SETTLEMENTS.

        (a)  STANDSTILL ORDER.  The parties acknowledge that this First
Supplemental Agreement and the obligation of Dart and its affiliates and RSH to
close the transactions contemplated hereby, are subject to compliance by Dart
with Section 8 of the Standstill Order.  Within two (2) business days after the
date of execution and delivery of this First Supplemental Agreement, Dart shall
send written notice of the transactions contemplated by this First Supplemental
Agreement in accordance with the terms of Section 8 of the Standstill Order,
unless all parties entitled to notice pursuant to Section 8 of the Standstill
Order shall have executed and delivered to Dart a written waiver of such notice
in form acceptable to Dart.
Notwithstanding any other provision of this First Supplemental Agreement,
neither the Dart Parties (as defined in the REMA) nor any of their affiliates
nor RSH shall be obligated to enter into any agreement or perform any
transaction contemplated by Section 1.1 or 1.3 until such time as the seven (7)
day notice period under Section 8 of the Standstill Order has expired or the
date that the written waiver of such notice shall have been executed and
delivered by all parties entitled to such notice pursuant to section 8 of the
Standstill Order, or if later, such date as no temporary restraining order,
preliminary injunction, permanent injunction or other court order (any of the
foregoing referred to as a "Settlement Injunction") is in effect that restrains
Dart or any affiliate of Dart from entering into such agreement or performing
such transaction.

                 (b)      NO SEVERABILITY OF SUPPLEMENTAL SETTLEMENT DOCUMENTS.
The parties intend that the execution and delivery of the Supplemental
Settlement Documents (as defined in Section 1.3(a)), other than this First
Supplemental Agreement, and the performance of the transactions contemplated by
this First Supplemental Agreement are mutually dependent on





                                       3
<PAGE>   4
each other and that no Supplemental Settlement Document (other than this First
Supplemental Agreement) shall become effective, and none of the transactions
contemplated hereby to occur on the First Supplemental Closing Date shall be
consummated, unless all the transactions contemplated by this First
Supplemental Agreement and the other Supplemental Settlement Documents to occur
on the First Supplemental Closing Date are consummated simultaneously.

                 1.3       CLOSING.

                 (a)  Dart and RSH agree to execute and deliver the documents
and instruments and consummate the transactions set forth in Section 1.1 (all
such documents, together with this First Supplemental Agreement and the
documents and instruments executed pursuant thereto, referred to herein as the
"Supplemental Settlement Documents") to which either is a party at a closing
(the "First Supplemental Closing") that shall take place at the offices of
Jones, Day, Reavis & Pogue, 1450 G Street, N.W., Washington, D.C. 20005 on the
First Supplemental Closing Date, as defined below, subject to the outside date
set forth in Section 1.1 hereof.  Except as otherwise provided herein, all
payments to be made as part of the closing of the transactions contemplated by
the Supplemental Settlement Documents shall be made by certified check, bank
check or wire transfer of immediately available funds pursuant to written
instructions from the party entitled to receive the payment.

                 (b)  The First Supplemental Closing shall occur on the "First
Supplemental Closing Date", which shall be the date on which the Warehouse
Plans shall have become effective in accordance with their terms, subject to
the outside closing date set forth in Section 1.1 hereof, it being the
intention of the parties that the Effective Date of each of the Warehouse Plans
(as defined therein, respectively) and the First Supplemental Closing Date
shall all occur simultaneously.

                 (c)  On the date of the First Supplemental Closing the parties
shall execute and deliver the Supplemental Settlement Documents and consummate
the transactions set forth in Section 1.1.  The obligation of the Dart Parties
and their affiliates and RSH to consummate the First Supplemental Closing, and
the effectiveness of any Supplemental Settlement Document (other than this
First Supplemental Agreement), shall be subject to the satisfaction in full of
the following conditions, on or before the outside closing date set forth in
Section 1.1 hereof:

                          (i) SUPPLEMENTAL SETTLEMENT DOCUMENTS.  Each of the
        Supplemental Settlement Documents shall have been executed and
        delivered;

                          (ii) ACKOWLEDGEMENTS OF EFFECTIVENESS OF PLANS OF
        REORGANIZATION.  RSH and Dart shall have caused to be executed and
        exchanged between them Acknowledgements of Effectiveness for the Plans
        in the forms attached hereto as Exhibit F;

                          (iii) PLANS OF REORGANIZATION.  The terms and
        conditions of the Warehouse Plans shall not have been amended, waived
        or modified from the form of the Warehouse Plans confirmed by orders of
        the Bankruptcy Court entered on or about





                                       4
<PAGE>   5
        June 12, 1997 without the written approval of Dart; all conditions
        precedent to the effectiveness of the Warehouse Plans and Dart's and/or
        Trak Auto Corporation's obligations thereunder shall have been
        satisfied in full but for closings having occurred with respect to the
        settlement agreements described in Section 13.01 (d) of each such Plan,
        it being the intention of the parties to this First Supplemental
        Agreement that such closings shall be simultaneous with the First
        Supplemental Closing; and the Warehouse Plans shall otherwise remain in
        full force and effect in accordance with their respective terms; and

                          (iv)  RSH ESCROW ACCOUNT.  On the First Supplemental
        Closing Date, $1,550,180 of the funds in the RSH Escrow Account shall
        be disbursed to Dart in consideration of the withholding obligation
        arising from the termination of the Options for 197,048 Class B Shares
        pursuant to Section 8.2(a) of REMA, as amended by the First Amendment
        to REMA (and upon such disbursement, RSH shall have no right, title or
        interest in or claim to the funds so disbursed), and the balance of the
        funds in the RSH Escrow Account shall be disbursed to RSH.  RSH shall
        indemnify Dart with respect to all such disbursements in accordance
        with the provisions of Article 6 of this First Supplemental Agreement
        and Section 10 of the First Amendment to REMA

                              ARTICLE 4. COVENANTS

                 4.1      COOPERATION.  The parties shall cooperate in the
defense of any litigation challenging the validity of this First Supplemental
Agreement, the RGL/Dart Settlement Agreement or the RSH/Dart Settlement
Agreement and the transactions contemplated hereby and thereby.  RSH hereby (a)
consents to the RGL/Dart Settlement Agreement and the transactions contemplated
thereby, (b) agrees to not file any lawsuit or initiate any proceeding
challenging the RGL/Dart Settlement Agreement or any of the transactions
contemplated thereby, and (c) waives and releases any claims he may have
against Dart, its affiliates, directors and officers arising out of or in
connection with the RGL/Dart Settlement Agreement and the transactions
contemplated thereby except for that certain right of indemnity under Section
7.4 of the Real Estate Master Agreement, as amended by the First Amendment to
Real





                                       7
<PAGE>   8
Estate Master Agreement, pursuant to which Dart has agreed to indemnify RSH
against fifty percent (50%) of any claims by Robert M. Haft or Linda G. Haft
for a "gross-up" of income taxes due on payments of $4,400,000 in the aggregate
made to such individuals by Dart with respect to Seventy-Fifth Avenue
Associates Limited Partnership, Trak Chicago Limited Partnership I, 75th Avenue
Tier II Limited Partnership or Trak Chicago Tier II Limited Partnership.

                 4.2      FURTHER ASSURANCES.  RSH and the Dart Parties each
shall execute and deliver, and RSH shall cause to be executed and delivered,
promptly such additional documents, assignments, certificates and instruments
as the other party to this First Supplemental Agreement may reasonably request
in order to effectuate more effectively the transactions contemplated by the
Supplemental Settlement Documents.

                 4.3       SPECIFIC PERFORMANCE.  The Dart Parties and RSH each
acknowledge and agree that in the event of any breach of this First
Supplemental Agreement or any other Supplemental Settlement Document, the
non-breaching party would be irreparably harmed and could not be made whole by
monetary damages.  It is accordingly agreed that the Dart Parties and RSH, in
addition to any other remedy to which they may be entitled at law or in equity,
shall be entitled to compel specific performance (including temporary
restraining orders) of this First Supplemental Agreement or any other
Supplemental Settlement Document in any action instituted in the Delaware Court
of Chancery or the United States District Court for the District of Delaware,
or, in the event neither of said courts would have jurisdiction over such
action, in any court of the United States or any state having subject matter
jurisdiction.  The Dart Parties and RSH each consent to non-exclusive personal
jurisdiction in any such action brought in the Delaware Court of Chancery or
the United States District Court for the District of Delaware.

                 4.4       LIQUIDATION DISTRIBUTIONS.  (a)  In the event that
at any time after both the First Supplemental Closing and the closing of the
Simultaneous Purchase, the Put Option or the Call Option (each as defined in
the Buy/Sell/Offering Agreement) the Board of Directors of Dart (as distinct
from any of its subsidiaries or affiliates), after adopting a plan of complete
liquidation or after dissolution of Dart has been authorized in accordance with
Section 275 of the Delaware General Corporation Law (or any successor or
comparable statutory provision then applicable), may determine to pay a
liquidating distribution to the shareholders of Dart (the "Liquidating
Distribution"), then Dart, at its election in its sole discretion, after
providing notice to RSH in the same manner and at the same time as any notice
of liquidation provided to Dart's shareholders, may elect, simultaneously with
the payment of such Liquidating Distribution, to cap any and all actual and
contingent liabilities that it or any Dart Affiliates or any of their
respective affiliates may have to RSH for any reason, or to any other parties
arising out of the RSH/Dart Settlement Agreement and the transactions pursuant
thereto, by the establishment of a reserve fund for such purpose in the Reserve
Amount (as defined below), it being understood that any unused portion of such
reserve fund may be withdrawn by or on behalf of Dart (or any liquidating
trustee for Dart) or distributed to Dart's shareholders at any time after
December 31, 2002.  For purposes of this Section 4.4(a), the Reserve Amount
shall be $1,000,000; provided, that if Dart commits funds in an escrow, trust,
letter of credit or similar arrangement for the payment, after the





                                       8
<PAGE>   9
Liquidating Distribution, of indemnification claims by members of the Executive
Committee or other members of Dart's Board of Directors, then the Reserve
Amount shall be equal to the greater of (i) one-third of the amount of funds so
committed or (ii) $1,000,000.

        (b)      The establishment of a reserve fund in accordance with clause
(a) of this Section 4.4 shall be effective to limit to the amount in such
reserve fund any and all actual and contingent liabilities that Dart or any
Dart Affiliates or any of their respective affiliates may have to RSH for any
reason, or to any other parties arising out of the RSH/Dart Settlement
Agreement and the transactions pursuant thereto, other than to the extent set
forth in clause (c) below; provided that each of the following conditions shall
have been satisfied:  (i) notice of Dart's intention to make a Liquidating
Distribution (the "Liquidating Distribution Notice") was given no earlier than
one (1) year after the date of the First Supplemental Closing, and (ii) the
Liquidation Date shall have occurred no earlier than 240 calendar days after
the Liquidating Distribution Notice was given.

        (c)      Notwithstanding anything contained herein to the contrary,
nothing in this Section 4.4 shall limit (i) Dart's obligations to indemnify RSH
for pending or threatened claims of which Dart has written notice not later
than 60 days before the Liquidation Date or (ii) the coverage of RSH under any
policy of directors and officers liability insurance policy in effect at any
time.

                            ARTICLE 5. EFFECTIVENESS

                 5.1      LIMITED INITIAL EFFECTIVENESS OF AGREEMENT.

        (a)      Notwithstanding any other provision of this First Supplemental
Agreement, none of the agreements, obligations or commitments of Dart set forth
in this First Supplemental Agreement shall be effective on or prior to October
26, 1997 (except that Dart shall be obligated to give written notice of this
First Supplemental Agreement pursuant to Section 8 of the Standstill Order to
the other persons subject to the Standstill Order, not later than October 18,
1997 , unless all parties entitled to notice pursuant to Section 8 of the
Standstill Order shall have executed and delivered to Dart a written waiver of
such notice in form acceptable to Dart).

        (b)      This Agreement shall be null, void and of no effect, ab
initio, if on or before October 26, 1997 the Delaware Court of Chancery issues
any order, writ, injunction or decree restraining, enjoining or prohibiting in
any way the effectiveness of this First Supplemental Agreement or the
consummation of any of the transactions contemplated by this First Supplemental
Agreement.

5.2     RSH BOUND

        All of the provisions of this First Supplemental Agreement shall be
binding on and effective with respect to RSH from the date stated in the first
sentence of this First Supplemental Agreement.  RSH hereby acknowledges that
adequate and valid consideration





                                       9
<PAGE>   10
has been received for his agreement to be bound to all of the provisions of
this First Supplemental Agreement from this date, notwithstanding Dart's right
to elect not to be bound pursuant to Section 5.1.

         ARTICLE 6.  RSH INDEMNIFICATION AS TO CERTAIN ESCROW ACCOUNTS

        6.1  RSH hereby agrees that he shall defend, indemnify and hold Dart,
its respective subsidiaries and affiliates, and each of their respective
officers, employees, directors, agents and representatives (the "Dart Parties")
harmless from and against any and all demands, claims, actions, suits,
proceedings, losses, damages, judgments, liabilities, costs and expenses,
including, without limitation, fees and expenses of legal counsel
(collectively, "Costs") asserted against or incurred by any Dart Party,
directly or indirectly, that arises from or in connection with any actual or
prospective release, distribution, withdrawal or other disposition of funds in
either the C-M Escrow Account or the RSH Escrow Account, as such terms are
defined in the REMA (whether to, in favor of, or for the benefit of RSH, Dart
or other person or entity) and that is based upon a claim or assertion that
such actual or prospective release, distribution, withdrawal or other
disposition violates or is subject to any security interest, lien or right of
Herbert H. Haft, Robert M. Haft, Mary Z. Haft, Linda G. Haft, New Frontiers
Investments LLC, Acquiport Midatlantic Retail, Inc., and any other person or
entity.  As soon as is reasonably practicable after any Dart Party becomes
aware of any claim that it has to recover Costs under this Section 6.1, such
Dart Party shall notify RSH in writing, which notice shall describe the claim
in reasonable detail, and shall indicate the amount (estimated, if necessary
and to the extent feasible) of the claim.  The failure of any Dart Party to
promptly give RSH such notice shall not preclude such Dart Party from obtaining
indemnification under this Section 6.1, except to the extent that such failure
has materially prejudiced RSH's rights or materially increased RSH's
liabilities and obligations hereunder.  In the event of a third party claim
which is subject to indemnification under this Section 6.1, RSH shall have the
right, upon agreeing in writing that he is obligated to fully indemnify the
Dart Party for the full amount of the claim (to the extent such claim is proven
or settled) and providing satisfactory evidence to the Dart Party that RSH has
sufficient financial resources to provide such indemnification and defend such
claim properly, to assume the defense of such claim by counsel of his own
choosing reasonably acceptable to Dart.  The Dart Party and RSH shall cooperate
with one another in the defense of such claim, including the settlement of the
matter on the basis stipulated by RSH (with RSH being responsible for all costs
and expenses of such settlement).  If RSH within a reasonable time after notice
of a claim fails to vigorously defend the Dart Party, the Dart Party shall be
entitled to undertake the defense, compromise or settlement of such claim at
the expense of and for the account and risk of RSH.

                    CONTRIBUTION AND SUBORDINATION AGREEMENT


        THIS CONTRIBUTION AND SUBORDINATION AGREEMENT (this "Agreement"), dated
__________ __, 1997, is made by and among, Dart Group Corporation, A Delaware
corporation ("Dart"), HHH/RSH Tier II Limited Partnership, a Maryland limited
partnership (the "Retained Partnership"), Ronald S. Haft (RSH"), Herbert H.
Haft ("HHH"), the Releasing Guarantors listed on Schedule 1 hereto and the
Released Guarantors listed on Schedule 2 hereto.

                                    Recitals

A.      It is contemplated that Dart may make a $10 million loan (the "RSH/HHH
        Loan") pursuant to the RSH/HHH Loan Agreement (as such term is defined
        in the Settlement Agreement dated as of August 18, 1997, among Dart,
        certain Affiliates of Dart, Robert M. Haft, Gloria G. Haft and Linda G.
        Haft (the "Settlement Agreement")), repayment of which would be secured
        in party by, among other things, all of HHH and RSH's rights, title and
        interest in and to the Collateral (as defined in Section 2(a) of this
        Agreement) and the Retained Partnership.

B.      All of the parties to this Agreement, except Dart and the Retained
        Partnership, are parties to an Indemnification Agreement, dated as of
        July 31, 1994 (the "Indemnification Agreement"), under which HHH and
        RSH agreed to indemnify Robert M. Haft ("RMH"), Gloria G. Haft ("GGH")
        and Linda G. Haft ("LGH") and collectively "RGH") with respect to,
        among other things, "all claims . . . made or incurred by, or asserted
        against, any of [RGL]" in connection with all liabilities or
        obligations that RMH, LGH or GGH may have in connection with "all
        partnership, corporate and individually held interest of the Haft
        Family in that collection of entities, through which the Haft Family
        owns, operates or manages their privately held warehouses (the
        "Combined Entities") . . . ."   The Combined Entities, which include
        guaranteed these indemnification obligations of HHH and RSH to RGL.
        Each of the Combined Entities has certain rights to seek contribution
        from the other Combined Entities in the event that it pays more than
        its share of any of the guaranteed indemnification obligations.

C.      If Dart makes the RSH/HHH Loan, the Retained Partnership, pursuant to
        the terms and provisions of that certain Retained Partnership Guaranty,
        will become a Guarantor under the Indemnification Agreement.

D.      Dart is unwilling to make the RSH/HHH Loan unless the Releasing
        Guarantors (1) release all rights of contribution they may have against
        the Released Guarantors, and (2) subordinate any claims they now have,
        or may hereafter have in the Collateral to the claims of Dart.







<PAGE>   23
                                   Agreements

        NOW THEREAFTER, to induce Dart to enter into the RGL Settlement
Agreement, to enter into the RSH/HHH Loan Agreement and to make the loans
contemplated thereunder, the parties hereto hereby agree as follows:

        1.       Release of Released Guarantors.  Each of the Releasing
guarantors irrevocably and unconditionally hereby releases each of the Released
Guarantors from any and all manner of claims, demands, damages, actions, causes
of action, contracts, agreements, charges, sums of money, claims for attorney's
fees and lawsuits of every kind and description whatsoever, in law or equity,
whether known or unknown, for contribution, or otherwise (a "Claim") under, or
in connection with, the Indemnification Agreement, that certain Settlement
Agreement dated as of August __, 1997 between RSH and HHH, and any other
agreements pursuant to which any of the Released Guarantors are jointly,
severally, or jointly and severally liable in any respect to HHH, RSH, RMH,
GGH, LGH or any entity directly or indirectly controlled by one or more of such
persons.

        2.       Subordination of Claims.

                 (a)     Subordination of Claims.  Any Claim, however arising,
which any Releasing Guarantor may now or hereafter have in or against or with
respect to any of the Collateral shall be subject, junior and subordinate to
any Claim that Dart or any affiliate of Dart now or hereafter has against the
Guarantors for, or with respect to any Collateral for, the obligations owing to
Dart under the RSH/HHH Loan and to any unsecured Claim or Dart or any affiliate
of Dart against any Guarantor or the Retained Partnership to the extent that
Dart or such affiliate has any secured or unsecured Claims arising in
connection with or relating to the RSH/HHH Loan.  The term "Collateral" shall
mean: (i) all general and limited partnership interest or shares in Combined
Property/Forbes Limited Partnership, CP/Forbes Boulevard, Inc.,
Haft/Equities-Sully Plaza Limited Partnership, Combined Property/Ontario
Limited Partnership and 3301 Pennsy Drive Associates Limited Partnership
(collectively, the "Collateral Entities"); and (ii) all property of and
interests in the property of the Collateral Entities and of the Retained
Partnership, whenever acquired and wherever located, that is collateral
security for the indebtedness to Dart arising under the RSH/HHH Loan,
including, without limitation, any direct or indirect interests in the Rolling
Valley, Maryland City and Sully shopping centers and the 4600 Forbes Boulevard
office building (but excluding any other property or interest of RSH, HHH or of
the Releasing guarantors that may hereafter be acquired by any of the
Collateral Entities or the Retained Partnership, if and to the extent such
acquisition was for less than fair value.

                 (b)     Extent of Subordination.  The subordinations and
priorities specified herein are applicable irrespective of the time, manner or
order of attachment or perfection of any security interest in the Collateral,
or the time or order of filing of any financing statements, or the giving or
failure to give notice of the acquisition or expected acquisition of any
purchase money security interest or other security interest.  Such
subordinations and priorities shall remain effective notwithstanding the
amendment or modification of the documents governing the FSH/HHH Loan or
governing the grant of any security interest in the Collateral to secure
repayment of the indebtedness arising under the RSH/HHH Loan or the
commencement of a case by or against either Dart of any obligor under the
RSH/HHH Loan under Title 11 of the United
<PAGE>   24
States Code or any similar insolvency or moratorium laws; except that such
subordination shall not be effective to the extent that Dart hereafter
increases the principal amount owing under the RSH/HHH Loan or extends the
maturity date thereof.

                 (c)     Standstill.  Until all of the obligations owed to
Dart, or any affiliate of Dart, under the HHH/RSH Loan have been paid in full,
no Releasing Guarantor shall accept any payment from the Retained Partnership
or any entity constituting (or the partnership interest in which, or capital
stock of which, constitute) a part of the Collateral.  Each Releasing Guarantor
agrees to refrain from taking any action against the Collateral unless it shall
have obtained Dart's prior written consent or Dart shall have been repaid in
full for all amounts owing under the RSH/HHH Loan.  No Releasing Guarantor
shall obtain or take any action to obtain any judgment under which it could
attach or seize any of the Collateral in any way until Dart shall have been
repaid in full for all amounts owing under the RSH/HHH Loan.  If, prior to the
repayment in full of the RSH/HHH Loan, an RGH Release Party has been granted or
otherwise obtains possession of Collateral then, in addition to any obligations
or remedies imposed or provided under the Uniform Commercial Code (the "UCC")
or other applicable law, the RGL Release Parties shall hold such Collateral,
any right, title or interest therein and any proceeds thereof in trust for the
Dart Companies (the "Trust Property"), and turn over such Trust Property to the
Dart Companies as soon as practicable.

                 (d)     Rights on Default.  Each Releasing Guarantor
acknowledges that Dart has and is entitled to exercise all of the rights and
remedies of a secured creditor under the UCC with respect to the Collateral,
including, without limitation, the right to take possession of and dispose of
the Collateral after an event of default, and to accept the Collateral as
discharge of the obligations under the RSH/HHH Loan to the extent permitted
under the UCC.  If Dart were to elect to sell the Collateral in a public or
private sale, conducted in accordance with the UCC, any purchaser of all or any
part of the Collateral shall take such Collateral free and clear of all rights
and interests of any of the Releasing Guarantors (including, without
limitation, any rights or interests of any of the RGL Releasing Guarantors in
the property or assets of any of the Collateral Partnerships(, and the
Releasing Guarantors shall have such rights and interests in and to the
proceeds of any such sale, after payment in full of all obligations owed to
Dart or any affiliate of Dart under the HHH/RSH Loan, as may be provided under
the UCC.

        3.       No Challenge to Dart Company Rights in the Collateral.

        No Releasing Guarantor shall challenge the attachment, validity,
perfection, priority or extent of any Claim of Dart or any affiliate of Dart in
the Collateral or with respect to the Retained Partnership in any judicial,
administrative or alternative dispute resolution proceeding.

        4.       Waivers.

        No delay on the part of a party hereto in exercising any right, power
or privilege granted hereunder shall operate as a waiver thereof, and no
purported waiver of any default, breach or violation of any term or provision
contained herein shall be deemed to be a waiver of such term or provision
unless the waiver is in writing and signed by the waiving party.  No such
waiver shall in any event be deemed a waiver of any subsequent or other
default, breach or violation.  The rights or remedies herein expressly
specified are cumulative and not exclusive of any other rights and remedies
which the parties would otherwise have.

        5.       Severability; Enforceability.

        In case any provision of this Agreement shall be held to be illegal,
invalid or unenforceable under present or future laws effective while this
Agreement remains in effect, the legality, validity and enforceability of the
remaining provisions will not in any way be affected or impaired thereby.

        6.       Governing Law.

        This Agreement will be governed by and construed in accordance with the
laws of the Commonwealth of Virginia, without regard to its principles
concerning conflicts of law, and any actions under this Agreement may be
brought in the courts of the Commonwealth of Virginia or the United States
District Court for the Eastern District of Virginia.

        7.       Different Facts.

        Each Releasing guarantor specifically acknowledges that the facts with
respect to which this Agreement is executed may turn out to be other than or
different from the facts now known to or believed by it to be true, and that it
therefore expressly assumes the risk of the facts turning out to be different
and agrees that this Agreement shall be in all respects effective and not
subject to termination or rescission by reason of any different facts.

        8.       Notices.

        Notices given in connection with this Agreement shall be in writing and
be deemed to have been given when actually received by telecopy or otherwise or
five (5) days after being deposited in the United States mail, postage prepaid,
addressed to a party hereto at the address set forth below such party's
signature to this Agreement, or to such other address designated by such party
by notice to each other party.

        9.       Counterparts.

        This Agreement may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all of which together
shall constitute one and the same instrument.

        10.      Additional Parties.

        HHH agrees that on and after the date hereof he shall cause any
entities that he now or hereafter controls, directly or indirectly, which
entities are or become indemnitors/guarantors under the Indemnification
Agreement to become parties hereto and to execute and deliver to Dart, the
Retained Partnership and RSH a counterpart hereof.

        RSH agrees that on and after the date hereof, he shall cause any

Agreement to become parties hereto and to execute and deliver to Dart, the
Retained Partnership and HHH a counterpart hereof.

Settlement Agreement (the "HHH Settlement Lawsuit");

                 WHEREAS, in connection with the HHH Settlement Lawsuit and
other litigation challenging the transactions pursuant to the RSH/Dart
Settlement Agreement, the Delaware Court of Chancery entered an order (the
"Standstill Order") on December 6, 1995 that requires Dart to refrain from
taking or recognizing specified actions and that, in Section 8 of the
Standstill Order, requires Dart to give not less than seven (7) days' notice of
certain "extraordinary transactions" to the other parties to such lawsuits;

                 WHEREAS, concurrently with the execution and delivery of this

agreement pursuant to which Dart and HHH agree to settle the HHH Settlement

                 WHEREAS, RSH desires that Dart enter into and consummate the
transactions contemplated by the HHH/Dart Settlement Agreement in order to

substantial economic benefits of the RSH/Dart Settlement Agreement, which have

respect to like-kind exchanges, and (iv) Dart shall waive its right to the
additional interest kicker if the Loan is repaid during the first 5 years.

this Second Supplemental Agreement, RSH acknowledges and agrees that (i)
neither Dart nor any of its affiliates has made any express or implied

the transactions contemplated thereby will be consummated (and Dart hereby
expressly disclaims any such representation, warranty or covenant) and (ii)
neither Dart nor any of its affiliates shall have any liability to RSH in the
event (A) the HHH/Dart Settlement Agreement does not become effective or (B) a
closing under the HHH/Dart Settlement Agreement does not occur and/or the

                 6.3      SPECIFIC PERFORMANCE.  Dart and RSH each acknowledge
and agree that in the event of any breach of this Second Supplemental
Agreement, the Voting Trust Amendment or the Buy/Sell Amendment or the
Contribution Agreement, the non-breaching party would be irreparably harmed and
could not be made whole by monetary damages.  It is accordingly agreed that

of the United States or any state having subject matter jurisdiction.  Dart and
RSH each consent to non-exclusive personal jurisdiction in any such action
brought in the Delaware Court of Chancery or the United States District Court
for the District of Delaware.

        10.      INTEREST RATE; INTEREST PAYMENTS.

                 (a)  Commencing as of the date hereof and continuing until
repayment in full of all sums due under this Agreement, the Principal Amount
shall bear interest at the Applicable Interest Rate.  Payments of interest only
on the Principal Amount shall be payable to Lender on the first day of each
calendar month from and after the date hereof.

                 (b)  Notwithstanding Section 3(a) above, during the period
commencing on the date hereof and ending on the date which is the fifth (5th)
anniversary of the date of this Agreement, Borrower shall pay to Lender, on the
first day of each calendar month, interest only on the Principal Amount at the
rate of four percent (4%) per annum.  The difference between the interest
payable under Section 3(a) above and that paid under this subsection shall
accrue and be added to the Principal Amount but without any interest thereon
until such fifth (5th) anniversary.  (By way of example and not of limitation,
if no principal payments are made for the first five years, then:  the
difference between the earn rate under Section 3(a) above and the pay rate
under this subsection is 8% - 4% = 4%/year; 4%/year times $10,000,000 =
$400,000 of deferred accrued interest becoming principal, without further
interest accruing, per year; $400,000/year times 5 years = $2,000,000 of
additional principal; $10,000,000 of original principal + $2,000,000 of
additional principal = an aggregate principal balance of $12,000,000 after 5
years, all of which thereafter bears interest and is payable at 8%/year per
Section 3(a) above.)

        11.      ADDITIONAL INTEREST.  Upon repayment of the Loan in full,
whether before, on or after the Maturity Date (without hereby implying that the
Loan will not be in default if not paid in full on the Maturity Date), Borrower
shall pay to Lender, as "Additional Interest," an amount equal to the
difference between (i) the amount that Lender would have received if the
Applicable Interest Rate throughout the term of the Loan was eleven percent
(11%) per annum, compounded monthly, and (ii) the amount of interest actually
paid to Lender by Borrower with respect to the Loan; provided, however, the
obligation to pay Additional Interest pursuant to the provisions of this
Section shall be limited to the extent by which the Net Property Value exceeds
(x) the original Principal Amount plus accrued interest thereon at the
Applicable Interest Rate plus (y) the original principal balance plus accrued
interest thereon at a rate not to exceed the Applicable Interest Rate under all
Haft-family Loans.





                                       14
<PAGE>   26

        12.      LATE CHARGE.  In the event that any payment due under the
terms of this Agreement (except the payment due on the Maturity Date) is not
received by Lender within five (5) days after the date such non-Maturity Date
payment is due (inclusive of the date when due), Borrower shall pay to Lender
on demand a late charge equal to five percent (5%) of such payment or the
maximum rate provided by law.  In the event that any payment due under the
terms of this Agreement on the Maturity Date is not received by Lender within
thirty (30) days after the Maturity Date (inclusive of the Maturity Date),
Borrower shall pay to Lender on demand a late charge equal to five percent (5%)
of such payment or the maximum rate provided by law.

        13.      DEFAULT INTEREST RATE.  Upon the occurrence of an Event of
Default (hereinafter defined), all amounts due hereunder shall bear interest
thereafter until such Event of Default is cured at a rate which is at all times
equal to three percent (3%) per annum in excess of the rate of interest
announced publicly by Citibank, N.A. in New York, New York from time to time as
Citibank N.A.'s base rate or prime rate (which is not necessarily the lowest
rate offered to borrowers by Citibank, N.A.).

        14.      PREPAYMENT.  Borrower may prepay the Principal Amount in whole
or in part, at any time or from time to time without premium or penalty.

        15.      MANNER AND APPLICATION OF PAYMENTS.  All payments on account
of the Loan shall be paid in lawful money of the United States of America in
immediately available funds, without offset, deduction or recoupment.  All
payments, including prepayments, made on account of the Loan, regardless of how
the same may be designated by Borrower, shall be applied first to the payment
of any late charge, costs, expenses and all other amounts (other than principal
and interest) due hereunder, second, to the payment of accrued and unpaid
interest then due hereunder, and the remainder, if any, shall be applied to the
outstanding Principal Amount; provided, however, if an Event of Default has
occurred, Lender shall have the right to apply such payments in such order as
Lender shall determine in its sole discretion.  If any payment of principal,
interest or other amounts to be made hereunder shall become due on a day other
than a Business Day, such payment may be made on the next succeeding Business
Day (unless the result of such extension of time would be to extend the date
for such payment into another calendar month or beyond the Maturity Date; in
any such event, payment shall be made on the Business Day immediately preceding
the day on which such





                                       15
<PAGE>   27
payment would otherwise have been due) and such extension of time shall in such
case be included in computing the interest, if any, in connection with such
payment.

and guaranteed by the Loan Documents.

        discharge from liability hereon, in whole or in part, on account of any
        facts or circumstances other than full and complete payment of all
        amounts due hereunder, including, but not limited to, all rights to the
        benefits of any statute of limitations and any moratorium,
        appraisement, exemption or homestead law now provided or which may

        extensions, renewals and modifications hereof; provided, however, that
        the foregoing waiver shall not apply to any one homestead claimed by
        RSH in the State of Florida;

        Lender to diligently collect the sums due hereunder;

                         (iv)  all other defenses available to sureties and
        guarantors generally.

                 (b)  Each Obligor (i) agrees that Lender, at any time or
times, without notice to it or its consent, may grant extensions of time,
without limit as to the number or the aggregate period of such extensions, for
the payment of any principal or interest due hereon, or other accommodations

record against any person or entity under the name or names of the Guarantors,
or any of them, and not listed on Exhibit J are not against the Guarantors, but

bankruptcy have been instituted by or against the Guarantors, or any of them,
nor have the Guarantors, or any of them, made an assignment or assignments for

        20.      COVENANTS OF BORROWER.  Borrower covenants and agrees with
Lender as follows:

                 (a)     Borrower shall maintain in good standing its
existence, franchises, rights and privileges under the laws of the jurisdiction
of its organization and its rights to transact business in the State of
Maryland and the Commonwealth of Virginia.  Borrower shall not, and shall not
permit the Partnerships or Combined Properties/Forbes Boulevard Limited
Partnership or CP/Forbes Boulevard, Inc. to, dissolve, terminate or otherwise
dispose, directly or indirectly or by operation of law, of all or substantially
all of its or their assets except as set forth in Section 14(b) below or in any
other Loan Document to which Combined Properties/Forbes Boulevard Limited
Partnership or CP/Forbes Boulevard, Inc. is a party, or, without giving Lender
at least sixty (60) days prior written notice, change its or their legal
structure or name.  Borrower shall not admit, or allow any of the Partnerships
or Combined Properties/Forbes Boulevard Limited Partnership to admit, any new
partner therein, nor shall Borrower allow any new shareholder in CP/Forbes
Boulevard, Inc. or any new member in RSH GP LLC.  Borrower shall not amend its,
nor permit the amendment of the Partnerships' or Combined Properties/Forbes
Boulevard Limited Partnership's partnership agreements (or their limited
partnership certificates) in any way that could adversely affect (i) Borrower's
ability to repay the Loan or perform its other obligations under the Loan
Documents, (ii) the collateral pledged under the Loan Documents or (iii)
Lender's rights and remedies





                                       23
<PAGE>   35
under the Loan Documents, without the prior written consent of Lender.

                 (b)     Borrower will comply with all covenants, obligations
and restrictions set forth in the Existing Mortgages or any Refinancing
thereof, including, but not limited to, the covenants regarding maintenance and
repair, payment of taxes and assessments, insurance requirements, and
compliance with applicable laws.

                 (c)     Borrower will provide Lender with a copy of any notice
of default received by Borrower from the holder of any mortgage encumbering the
Properties or any portion thereof within two (2) Business Days after receipt
thereof by Borrower.

                 (d)     Borrower shall make the capital expenditures
contemplated by the terms of the bankruptcy plans of reorganization applicable
to each Property as and when required thereunder, as such plans of
reorganization have been approved by Lender.

                 (e)     Borrower shall comply and shall cause the Partnerships
to comply in all material respects with all covenants and obligations of the
landlord set forth in all leases of space in the Properties or any portion
thereof.

                 (f)     Borrower shall cause the Partnerships to amend their
existing respective management agreements with Combined Properties Incorporated
to provide (or enter into new management agreements with Combined Properties
Incorporated providing) that, if Lender or any successor to Lender (whether at
foreclosure sale or otherwise) gains control of any such Partnership, the
management agreement between that Partnership and Combined Properties
Incorporated may be terminated by that Partnership without cause and without
payment of any termination fee or penalty of any type on not less than thirty
(30) days written notice to Combined Properties Incorporated.  The foregoing
does not supersede the rights of any mortgagee under an Existing Mortgage.

                 (g)     Borrower shall cause Capital Resources Limited
Partnership to amend the HCP Notes made by HESPLP and by Combined
Properties/Forbes Boulevard Limited Partnership to provide that if Lender or
any successor to Lender (whether at foreclosure sale or otherwise) gains
control of either of such partnerships, the HCP Note made by that partnership
shall automatically be deemed





                                       24
<PAGE>   36
cancelled and all debt evidenced thereto or incurred pursuant thereto forgiven.

        21.      NEGATIVE COVENANTS OF BORROWER.  Borrower covenants and agrees
with Lender that it shall not:

                 (a)     Terminate, cancel, amend, modify or otherwise alter
any of the management agreements related to the Properties entered into with
Combined Properties Incorporated without the prior written consent of Lender
(except pursuant to a plan of reorganization approved by Lender) or enter into
a new management agreement affecting one or more of the Properties without the
prior written consent of Lender.

                 (b)     Permit the Partnerships to, whether voluntarily or
involuntarily, sell, grant, convey, assign or otherwise transfer, by operation
of law or otherwise, the Properties or any part thereof, without the prior
written consent of Lender except as an Arms-Length Sale to an unrelated third
party with the Net Sales Proceeds being paid to Lender or, in the absence of an
Arms-Length Sale, with the Net Property Value under Section 1(y)(ii) above
being paid to Lender.

                 (c)     Permit the Partnerships to enter into a Refinancing
with respect to the Properties or any part thereof without the prior written
consent of Lender unless such refinancing is on commercially reasonable terms
(including, without limitation, requiring regular principal amortization, not
containing any participation or equity kicker, and otherwise being made on such
terms as life insurance companies are making permanent mortgage loans on the
date hereof), at market rates, and is structured in such a way so as to not
adversely prejudice Lender's interests with the Net Refinancing Proceeds being
paid to Lender.  In no event shall any second mortgage financing be permitted.
Borrower shall not and shall not permit the Partnerships to permit any lien,
encumbrance, charge, assessment or imposition (other than the Existing
Mortgages or such permitted Refinancing) to become due and payable out of or in
respect of, or become a lien on, the Properties or any part thereof without the
prior written consent of Lender.

                 (d)     Permit any Partnership to enter into any new lease
with respect to more than 50,000 square feet of space in the Properties or any
portion thereof without the prior written consent of Lender.





                                       25
<PAGE>   37
                 (e)     Permit or allow, or permit or allow the Partnerships
to permit or allow, any Hazardous Substance to (i) affect, (ii) be generated on
or deposited upon, (iii) be incorporated into, (iv) be transported to or from,
or (v) be stored on the Properties or any portion thereof, except as
customarily done by tenants in the normal course of business and in compliance
with applicable law; provided, however, that Borrower shall not be in default
of this subsection if a non-Affiliate does any of the foregoing without
Borrower's knowledge or with Borrower's knowledge but Borrower is unable to
prevent it.

                 (f)     Prepay any Haft-family Loan without the prior written
consent of Lender except when required to do so by the terms of the loan
documents applicable to that Haft-family Loan.

                 (g)     Nor shall Borrower permit any Partnership or any
partner of any Partnership to indemnify or guaranty the obligations of any
third party except as specifically contemplated by the Loan Documents.

                 22.     EVENTS OF DEFAULT.  The occurrence of any one or more
of the following events shall constitute an event of default (individually, an
"Event of Default" and collectively, the "Events of Default") under this
Agreement:

                 (a)     Lender has not actually received any payments (other
than payments due on the Maturity Date) due and payable by Borrower to Lender
under the terms of this Agreement including, but not limited to, payments of
principal and interest (including Additional Interest), within five (5) days
after giving written notice to Borrower that any such payment is overdue;
provided, however, that Lender need not give such notice more than two (2)
times in any calendar year and thereafter during any calendar year an Event of
Default shall exist if Lender has not actually received any payments (other
than payments due on the Maturity Date) due and payable by Borrower to Lender
under the terms of this Agreement including, but not limited to, payments of
principal and interest (including Additional Interest), within five (5) days
after the date due;

                 (b)     Lender has not actually received all payments due and
payable at the Maturity Date, including, but not limited to, the Principal
Amount, accrued interest thereon and Additional Interest;

                 (c)     failure of Borrower to perform, observe or comply with
any non-monetary agreement, covenant or promise made under this Agreement or
under any of the other Loan Documents and not covered elsewhere in this section
if such failure continues beyond any applicable notice and cure period set
forth elsewhere in this Agreement or the Loan Documents or, if no notice and
cure period is specified, if such failure continues for more than thirty (30)
days after written notice thereof is given to Borrower; provided, however, that
no Event of Default shall exist if such failure is not reasonably capable of
being cured in such thirty (30) day period but Borrower begins its cure within
such period and thereafter diligently prosecutes such cure to successful
completion within an additional sixty (60) day period;

                 (d)     the occurrence of a default or an event of default by 
any party other than Borrower under the terms and conditions of any of the
other Loan Documents (including, without limitation, the Guaranty), which
default or event of default remains uncured beyond any applicable grace and/or
cure period provided therefor;

                 (e)     if Borrower has made any representation or warranty in
this Agreement or any other Loan Document that contains any untrue statement of
a material fact or omits a material fact necessary to make such representation
or warranty not misleading in a material and adverse manner;

                 (f)     if Borrower or any Partnership sells, assigns,
transfers, pledges or encumbers, or allows to be sold, assigned, transferred,
pledged or encumbered, any interest or asset subject to the liens granted to
Lender under any other Loan Documents, except as may be expressly permitted by
this Agreement, without the prior written consent of Lender;

                 (g)     the occurrence of any default under any other
borrowing if the result of such default would permit the acceleration of the
maturity of any note, loan or other agreement between Borrower or any
Partnership and any person other than Lender;

                 (h)     the filing of any petition or relief under the United

                 (l)     if any execution or attachment is levied against any
property of Borrower or any Partnership, and such execution or attachment is

Borrower or such Partnership to discharge the same, or cause it to be
discharged, or bonded off to Lender's satisfaction, within thirty (30) days
from the date of the order, decree or process under which or pursuant to which
such judgment was entered.

        23.      REMEDIES.

                 (a)  Upon the occurrence of an Event of Default, at the option
of Lender all amounts payable by Borrower to Lender under the terms of this
Agreement shall immediately become due and payable by Borrower to Lender
without notice to Borrower or any other person, and Lender shall have all of
the rights, powers and remedies available under the terms of this Agreement,
any of the other Loan Documents and all applicable laws.

                 (b)  If Lender exercises its remedies under this Agreement
or any other Loan Document, then, notwithstanding anything to the contrary
contained in any Loan Document or in any partnership agreement or certificate
of limited partnership, certificate or articles of incorporation, operating
agreement or other organizational document of any signatory to any Loan
Document, or in any agreement between members of the Haft family or their
Affiliates, whether or not disclosed to Lender before the making of the Loan,
neither Lender nor any entity that is or comes under the control of Lender
shall be bound to make any distributions, allocations, or other payments to any
member of





                                       28
<PAGE>   40
the Haft family or any Affiliate of any member of the Haft family under any
such document or agreement, or be bound to protect the tax position of any
member of the Haft family or any Affiliate of any member of the Haft family.
The foregoing includes, without limitation, any obligation of RSH, Borrower or
any partner in Borrower to protect Herbert H. Haft's tax position with respect
to Borrower or any of its assets.

        24.      EXPENSES; INDEMNIFICATION.

                 (a)     Borrower promises to pay to Lender on demand by Lender
all reasonable costs and expenses incurred by Lender in connection with the
collection and enforcement of this Agreement or any portion thereof or the
enforcement of any other Loan Document, including, without limitation, all
reasonable attorneys' fees and expenses, investigation costs, and all court
costs, whether or not suit is filed hereon, whether before or after the
Maturity Date, or whether in connection with bankruptcy, insolvency or appeal,
or whether collection is made against Borrower or any Guarantor or endorser or
any other person primarily or secondarily liable hereunder.

                 (b)     Borrower shall defend, indemnify and hold Lender
harmless from and against all fines, liabilities, obligations, claims, damages,
penalties, causes of action, costs and expenses imposed upon or incurred by or
asserted against Lender by reason of any matter whatsoever relating to this
Agreement, the Loan Documents and/or the Properties or the use, non-use or
condition of any thereof (except to the extent caused by the gross negligence
or willful misconduct of Lender or its agents) and/or by reason of any failure
by Borrower to perform any Obligations.

                 (c)     Borrower agrees to indemnify and hold Lender harmless
from and against all fines and penalties and liabilities, including all
foreseeable and unforeseeable consequential damages and any other damages,
costs, and losses, including reasonable attorneys fees, directly or indirectly
and in whole or in part arising out of or attributable to Hazardous Substances
existing beneath or on the surface of the Properties or any part thereof at any
time or the migration thereof within or from the Properties at any time,
including, without limitation, the cost of any remedial, removal, response,
abatement, clean-up, investigative and monitoring costs and any other related
costs and expenses.  If any action, suit or other proceeding is brought against
Lender by reason of any such occurrence, Lender shall have the right, at
Borrower's expense,





                                       29
<PAGE>   41
to defend against such proceeding or require Borrower, at Borrower's expense,
to defend such proceeding by counsel designated by Lender.

                 (d)     The provisions of this Section shall survive repayment
of the Loan.

        25.      SECURITY; GUARANTY.  The Loan is secured by, among other
things, the Pledge Agreements and is guaranteed by the Guaranty.

        26.      REMEDIES CUMULATIVE.  Each right, power, and remedy of Lender
as provided for in this Agreement or any of the other Loan Documents, or now or
hereafter existing under any applicable law or otherwise shall be cumulative
and concurrent and shall be in addition to every other right, power, or remedy
provided for in this Agreement or any of the other Loan Documents or now or
hereafter existing under any applicable law, and the exercise or beginning of
the exercise by Lender of any one or more of such rights, powers, or remedies
shall not preclude the simultaneous or later exercise by Lender of any or all
such other rights, powers, or remedies.  No failure or delay by Lender to
insist upon the strict performance of any term, condition, covenant, or
agreement of this Agreement or any of the other Loan Documents, or to exercise
any right, power, or remedy consequent upon a breach thereof, shall constitute
a waiver of any such term, condition, covenant, or agreement or of any such
breach, or preclude Lender from exercising any such right, power, or remedy at
a later time or times.  By accepting payment after the due date of any amount
payable under the terms of this Agreement, Lender shall not be deemed to waive
the right either to require prompt payment when due of all other amounts
payable under the terms of this Agreement or to declare an Event of Default for
the failure to effect such prompt payment of any such other amount.  No
provision hereof may be waived or modified orally, but all such waivers or
modifications shall be in writing, expressly waiving or modifying such
provision and signed by the party against whom enforcement of any waiver or
modification is sought.  No course of dealing or conduct shall be effective to
amend, modify, waive, release, or change any provisions of this Agreement.

        27.      GOVERNING LAW; CONSENT TO JURISDICTION.  The provisions of
this Agreement shall be construed, interpreted and enforced in accordance with
the laws of the State of Maryland, without regard to conflicts of laws, as the
same may be in effect from time to





                                       30
<PAGE>   42
time.  Borrower irrevocably submits to the non-exclusive jurisdiction of any
state or federal court sitting in the State of Maryland or in the State of
Delaware over any suit, action, or proceeding arising out of or relating to
this Agreement or any other Loan Document.  Borrower hereby agrees that Lender
shall have the option, in its sole discretion, to lay the venue of any such
suit, action or proceeding in any of the aforementioned courts.  Borrower
irrevocably waives, to the fullest extent permitted by law, any objection that
Borrower may now or hereafter have to laying the venue of any such suit,
action, or proceeding brought in any such court and any claim that any such
suit, action, or proceeding brought in any such court has been brought in an
inconvenient forum.  Borrower agrees that a final judgment (for which there is
no more right of appeal) in any such suit, action or proceeding brought in such
a court shall be conclusive and binding upon Borrower.

        28.      SERVICE OF PROCESS.

                 (a)     Borrower hereby irrevocably designates and appoints
RSH as Borrower's authorized agent to accept and acknowledge on Borrower's
behalf service of any and all process that may be served in any suit, action,
or proceeding instituted in connection with this Agreement or any other Loan
Document in any state or federal court sitting in the State of Maryland or in
the State of Delaware.  If such agent shall cease so to act, Borrower shall
irrevocably designate and appoint without delay another such agent satisfactory
to Lender and shall promptly deliver to Lender evidence in writing of such
agent's acceptance of such appointment and its agreement that such appointment
shall be irrevocable.

                 (b)     Borrower hereby consents to process being served in
any suit, action, or proceeding instituted in connection with this Agreement or
any other Loan Document by the mailing of a copy thereof by certified mail,
postage prepaid, return receipt requested, to the agent hereinabove designated
and appointed by Borrower as Borrower's agent for service of process.  Borrower
irrevocably agrees that such service shall be deemed to be service of process
upon Borrower in any such suit, action, or proceeding.  Nothing in this
Agreement shall affect the right of Lender to serve process in any manner
otherwise permitted by law and nothing in this Agreement will limit the right
of Lender otherwise to bring proceedings against Borrower in the courts of any
other jurisdiction or jurisdictions.  Initiating such proceeding or taking such
action in any other jurisdiction or 





                                       31
<PAGE>   43
state shall not, however, constitute a waiver of the agreement contained
herein that the laws of the State of Maryland shall govern the rights and
obligations of the parties hereunder.

        29.      NOTICE.  Any notice, request, or demand to or upon Borrower or
Lender shall be in writing and shall be deemed given upon receipt (refusal to
accept delivery or inability to make delivery because of an incorrect or
outdated address provided by the intended recipient constituting receipt)
addressed as follows, unless any such address is changed by written notice
hereunder:

        30.      INVALIDITY OF ANY PART.  If this Agreement or any other Loan
Document or any one or more of the provisions contained in this Agreement or
any other Loan Document should be held to be invalid, illegal or unenforceable
in any respect, the validity, legality and enforceability of all remaining
provisions shall not in any way be affected or impaired.  Notwithstanding the
foregoing, if interest in excess of such maximum legal rate of interest
permitted to be charged Borrower under applicable laws shall be paid or payable
hereunder, then the rate imposed hereunder shall be reduced to such maximum
legal rate, and if from any circumstances Lender shall ever receive as interest
an amount which would exceed the maximum lawful rate, such amount which would
be deemed excessive interest shall be applied to the





                                       32
<PAGE>   44
reduction of the unpaid principal balance due hereunder and not to the payment
of interest.

        31.      COMMERCIAL PURPOSES.  Borrower represents, covenants and
warrants that the use of the proceeds of the Loan is a business or commercial
purpose and not a household or consumer purpose, that the Loan is not secured
by residential real property, and that the Loan is a "commercial loan" as
defined in Section 12-101(c) of the Commercial Law Article of the Annotated
Code of Maryland.

        32.      MISCELLANEOUS.

delivered pursuant hereto inure to the benefit of, and shall be binding upon,

also be deemed to be a reference to its successors, assigns, heirs, or personal
representatives.  Without limiting the generality of the foregoing, Lender
shall have the right to sell, transfer and/or assign this Agreement and the
other Loan Documents without the consent of Borrower.

                 (b)     Time is of the essence as to each of the provisions

agreements between them with respect to the subject matter hereof and all prior
negotiations between the parties are merged in this Agreement and the other
Loan Documents, and there are no promises, agreements, conditions,
undertakings, warranties or representations, oral or written, express or
implied, between them other than as herein set forth.

                 (e)     No waiver of any of the provisions of this Agreement
or any other agreement referred to herein shall be





                                       33
<PAGE>   45
valid unless in writing and signed by the party against whom it is sought to be
enforced.  The waiver by any party hereto of any matter provided for herein
shall not be deemed to be a waiver of any other matter provided for herein.

                 (f)     This Agreement may be amended only by a written
agreement executed by the parties hereto.

                 (g)     Notwithstanding the entry of any judgment under or in
connection with this Agreement, the outstanding principal balance of the Loan
shall continue to bear interest at the applicable rate or rates of interest
provided for in this Agreement unless required by law to bear a lower rate of
interest.

                 (h)     This Agreement may be executed in any number of
counterparts, each of which so executed shall be deemed to be an original but
all of which together shall constitute one and the same instrument.

                 (i)     The headings in this Agreement and the headings in the
exhibits hereto are solely for convenience of reference and shall not be given
any effect in the construction or interpretation of this Agreement.  Unless
otherwise specified, references in this Agreement to sections or exhibits are
references to sections of or exhibits to this Agreement.

                 (j)     Whenever this Agreement or any other Loan Document
requires a party to act reasonably, to not unreasonably withhold its consent,
to pay reasonable costs, expenses or fees, or otherwise uses or implies a
"reasonableness" standard and the parties disagree over whether such standard
has been met, the party challenging the reasonableness of the other party's
actions or challenging any cost, expense or fee charged to it or levied on it
shall have the burden of proof of proving the unreasonableness thereof and the
standard of proof shall be a "clearly erroneous" standard, which shall mean a
standard higher than the usual civil "preponderance of the evidence" or "more
likely than not" standard but lower than a criminal "beyond a reasonable doubt"
standard.

        33.      CONFESSION OF JUDGMENT.  UPON THE OCCURRENCE OF AN EVENT OF
DEFAULT, BORROWER HEREBY AUTHORIZES ANY ATTORNEY DESIGNATED BY LENDER OR ANY
CLERK OF ANY COURT OF RECORD TO APPEAR FOR BORROWER IN ANY COURT OF RECORD AND
TO CONFESS JUDGMENT WITHOUT PRIOR HEARING AGAINST BORROWER IN FAVOR OF

EXTINGUISHED BY ANY JUDGMENT ENTERED PURSUANT THERETO.  SUCH AUTHORITY MAY BE
EXERCISED ON ONE OR MORE OCCASIONS OR FROM TIME TO TIME IN THE SAME OR
DIFFERENT JURISDICTIONS AS OFTEN AS LENDER SHALL DEEM NECESSARY OR DESIRABLE,
FOR ALL OF WHICH THIS AGREEMENT SHALL BE A SUFFICIENT WARRANT.

        34.      WAIVER OF TRIAL BY JURY.  BORROWER HEREBY WAIVES TRIAL BY JURY
IN ANY ACTION OR PROCEEDING TO WHICH IT AND LENDER MAY BE PARTIES ARISING OUT
OF OR IN ANY WAY PERTAINING TO THIS AGREEMENT, THE LOAN OR THE LOAN DOCUMENTS.
IT IS AGREED AND UNDERSTOOD THAT THIS WAIVER CONSTITUTES A WAIVER OF TRIAL BY
JURY OF ALL CLAIMS AGAINST ALL PARTIES TO SUCH ACTIONS OR PROCEEDINGS,
INCLUDING CLAIMS AGAINST PARTIES WHO ARE NOT PARTIES TO THIS AGREEMENT.

        35.      REPRESENTATIONS OF BORROWER.  BORROWER REPRESENTS AND WARRANTS
THAT THE WAIVER OF TRIAL BY JURY AND THE CONFESSION OF JUDGMENT CONTAINED
HEREIN ARE KNOWINGLY, WILLINGLY AND VOLUNTARILY MADE BY BORROWER, AND BORROWER
HEREBY REPRESENTS THAT NO REPRESENTATIONS OF FACT OR AGREEMENTS HAVE BEEN MADE
BY ANY INDIVIDUAL TO INDUCE THE WAIVER OF TRIAL BY JURY OR CONFESSION OF
JUDGMENT OR TO IN ANY WAY MODIFY OR NULLIFY ITS EFFECT.  BORROWER FURTHER
REPRESENTS THAT IT HAS BEEN REPRESENTED IN THE SIGNING OF THIS AGREEMENT AND IN
THE MAKING OF THE WAIVER OF TRIAL BY JURY AND THE CONFESSION OF JUDGMENT BY
INDEPENDENT LEGAL COUNSEL, SELECTED OF ITS OWN FREE WILL, AND THAT IT HAS HAD
THE OPPORTUNITY TO DISCUSS THE WAIVER OF TRIAL BY JURY AND THE CONFESSION OF
JUDGMENT WITH SUCH COUNSEL.

        IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be

                    CONTRIBUTION AND SUBORDINATION AGREEMENT

        THIS CONTRIBUTION AND SUBORDINATION AGREEMENT (this "Agreement"), dated
__________ __, 1997, is made by and among, Dart Group Corporation, A Delaware
corporation ("Dart"), HHH/RSH Tier II Limited Partnership, a Maryland limited
partnership (the "Retained Partnership"), Ronald S. Haft (RSH"), Herbert H.
Haft ("HHH"), the Releasing Guarantors listed on Schedule 1 hereto and the
Released Guarantors listed on Schedule 2 hereto.

                                    Recitals

A.      It is contemplated that Dart may make a $10 million loan (the "RSH/HHH
        Loan") pursuant to the RSH/HHH Loan Agreement (as such term is defined
        in the Settlement Agreement dated as of August 18, 1997, among Dart,
        certain Affiliates of Dart, Robert M. Haft, Gloria G. Haft and Linda G.
        Haft (the "Settlement Agreement")), repayment of which would be secured
        in party by, among other things, all of HHH and RSH's rights, title and
        interest in and to the Collateral (as defined in Section 2(a) of this
        Agreement) and the Retained Partnership.

B.      All of the parties to this Agreement, except Dart and the Retained
        Partnership, are parties to an Indemnification Agreement, dated as of
        July 31, 1994 (the "Indemnification Agreement"), under which HHH and
        RSH agreed to indemnify Robert M. Haft ("RMH"), Gloria G. Haft ("GGH")
        and Linda G. Haft ("LGH") and collectively "RGH") with respect to,
        among other things, "all claims . . . made or incurred by, or asserted
        against, any of [RGL]" in connection with all liabilities or
        obligations that RMH, LGH or GGH may have in connection with "all
        partnership, corporate and individually held interest of the Haft
        Family in that collection of entities, through which the Haft Family
        owns, operates or manages their privately held warehouses (the
        "Combined Entities") . . . ."   The Combined Entities, which include
        guaranteed these indemnification obligations of HHH and RSH to RGL.
        Each of the Combined Entities has certain rights to seek contribution
        from the other Combined Entities in the event that it pays more than
        its share of any of the guaranteed indemnification obligations.

C.      If Dart makes the RSH/HHH Loan, the Retained Partnership, pursuant to
        the terms and provisions of that certain Retained Partnership Guaranty,
        will become a Guarantor under the Indemnification Agreement.

D.      Dart is unwilling to make the RSH/HHH Loan unless the Releasing
        Guarantors (1) release all rights of contribution they may have against
        the Released Guarantors, and (2) subordinate any claims they now have,
        or may hereafter have in the Collateral to the claims of Dart.
<PAGE>   53

                                   Agreements

        NOW THEREAFTER, to induce Dart to enter into the RGL Settlement
Agreement, to enter into the RSH/HHH Loan Agreement and to make the loans
contemplated thereunder, the parties hereto hereby agree as follows:

        1.       Release of Released Guarantors.  Each of the Releasing
guarantors irrevocably and unconditionally hereby releases each of the Released
Guarantors from any and all manner of claims, demands, damages, actions, causes
of action, contracts, agreements, charges, sums of money, claims for attorney's
fees and lawsuits of every kind and description whatsoever, in law or equity,
whether known or unknown, for contribution, or otherwise (a "Claim") under, or
in connection with, the Indemnification Agreement, that certain Settlement
Agreement dated as of August __, 1997 between RSH and HHH, and any other
agreements pursuant to which any of the Released Guarantors are jointly,
severally, or jointly and severally liable in any respect to HHH, RSH, RMH,
GGH, LGH or any entity directly or indirectly controlled by one or more of such
persons.

        2.       Subordination of Claims.

                 (a)     Subordination of Claims.  Any Claim, however arising,
which any Releasing Guarantor may now or hereafter have in or against or with
respect to any of the Collateral shall be subject, junior and subordinate to
any Claim that Dart or any affiliate of Dart now or hereafter has against the
Guarantors for, or with respect to any Collateral for, the obligations owing to
Dart under the RSH/HHH Loan and to any unsecured Claim or Dart or any affiliate
of Dart against any Guarantor or the Retained Partnership to the extent that
Dart or such affiliate has any secured or unsecured Claims arising in
connection with or relating to the RSH/HHH Loan.  The term "Collateral" shall
mean: (i) all general and limited partnership interest or shares in Combined
Property/Forbes Limited Partnership, CP/Forbes Boulevard, Inc.,
Haft/Equities-Sully Plaza Limited Partnership, Combined Property/Ontario
Limited Partnership and 3301 Pennsy Drive Associates Limited Partnership
(collectively, the "Collateral Entities"); and (ii) all property of and
interests in the property of the Collateral Entities and of the Retained
Partnership, whenever acquired and wherever located, that is collateral
security for the indebtedness to Dart arising under the RSH/HHH Loan,
including, without limitation, any direct or indirect interests in the Rolling
Valley, Maryland City and Sully shopping centers and the 4600 Forbes Boulevard
office building (but excluding any other property or interest of RSH, HHH or of
the Releasing guarantors that may hereafter be acquired by any of the
Collateral Entities or the Retained Partnership, if and to the extent such
acquisition was for less than fair value.

                 (b)     Extent of Subordination.  The subordinations and
priorities specified herein are applicable irrespective of the time, manner or
order of attachment or perfection of any security interest in the Collateral,
or the time or order of filing of any financing statements, or the giving or
failure to give notice of the acquisition or expected acquisition of any
purchase money security interest or other security interest.  Such
subordinations and priorities shall remain effective notwithstanding the
amendment or modification of the documents governing the FSH/HHH Loan or
governing the grant of any security interest in the Collateral to secure





                                       2
<PAGE>   54
repayment of the indebtedness arising under the RSH/HHH Loan or the
commencement of a case by or against either Dart of any obligor under the
RSH/HHH Loan under Title 11 of the United States Code or any similar insolvency
or moratorium laws; except that such subordination shall not be effective to
the extent that Dart hereafter increases the principal amount owing under the
RSH/HHH Loan or extends the maturity date thereof.

                 (c)     Standstill.  Until all of the obligations owed to
Dart, or any affiliate of Dart, under the HHH/RSH Loan have been paid in full,
no Releasing Guarantor shall accept any payment from the Retained Partnership
or any entity constituting (or the partnership interest in which, or capital
stock of which, constitute) a part of the Collateral.  Each Releasing Guarantor
agrees to refrain from taking any action against the Collateral unless it shall
have obtained Dart's prior written consent or Dart shall have been repaid in
full for all amounts owing under the RSH/HHH Loan.  No Releasing Guarantor
shall obtain or take any action to obtain any judgment under which it could
attach or seize any of the Collateral in any way until Dart shall have been
repaid in full for all amounts owing under the RSH/HHH Loan.  If, prior to the
repayment in full of the RSH/HHH Loan, an RGH Release Party has been granted or
otherwise obtains possession of Collateral then, in addition to any obligations
or remedies imposed or provided under the Uniform Commercial Code (the "UCC")
or other applicable law, the RGL Release Parties shall hold such Collateral,
any right, title or interest therein and any proceeds thereof in trust for the
Dart Companies (the "Trust Property"), and turn over such Trust Property to the
Dart Companies as soon as practicable.

                 (d)     Rights on Default.  Each Releasing Guarantor
acknowledges that Dart has and is entitled to exercise all of the rights and
remedies of a secured creditor under the UCC with respect to the Collateral,
including, without limitation, the right to take possession of and dispose of
the Collateral after an event of default, and to accept the Collateral as
discharge of the obligations under the RSH/HHH Loan to the extent permitted
under the UCC.  If Dart were to elect to sell the Collateral in a public or
private sale, conducted in accordance with the UCC, any purchaser of all or any
part of the Collateral shall take such Collateral free and clear of all rights
and interests of any of the Releasing Guarantors (including, without
limitation, any rights or interests of any of the RGL Releasing Guarantors in
the property or assets of any of the Collateral Partnerships(, and the
Releasing Guarantors shall have such rights and interests in and to the
proceeds of any such sale, after payment in full of all obligations owed to
Dart or any affiliate of Dart under the HHH/RSH Loan, as may be provided under
the UCC.

        3.       No Challenge to Dart Company Rights in the Collateral.

        No Releasing Guarantor shall challenge the attachment, validity,
perfection, priority or extent of any Claim of Dart or any affiliate of Dart in
the Collateral or with respect to the Retained Partnership in any judicial,
administrative or alternative dispute resolution proceeding.

        4.       Waivers.

        No delay on the part of a party hereto in exercising any right, power
or privilege granted hereunder shall operate as a waiver thereof, and no
purported waiver of any default, breach or violation of any term or provision
contained herein shall be deemed to be a waiver of such term





                                       3
<PAGE>   55
or provision unless the waiver is in writing and signed by the waiving party.
No such waiver shall in any event be deemed a waiver of any subsequent or other
default, breach or violation.  The rights or remedies herein expressly
specified are cumulative and not exclusive of any other rights and remedies
which the parties would otherwise have.

        5.       Severability; Enforceability.

        In case any provision of this Agreement shall be held to be illegal,
invalid or unenforceable under present or future laws effective while this
Agreement remains in effect, the legality, validity and enforceability of the
remaining provisions will not in any way be affected or impaired thereby.

        6.       Governing Law.

        This Agreement will be governed by and construed in accordance with the
laws of the Commonwealth of Virginia, without regard to its principles
concerning conflicts of law, and any actions under this Agreement may be
brought in the courts of the Commonwealth of Virginia or the United States
District Court for the Eastern District of Virginia.

        7.       Different Facts.

        Each Releasing guarantor specifically acknowledges that the facts with
respect to which this Agreement is executed may turn out to be other than or
different from the facts now known to or believed by it to be true, and that it
therefore expressly assumes the risk of the facts turning out to be different
and agrees that this Agreement shall be in all respects effective and not
subject to termination or rescission by reason of any different facts.

        8.       Notices.

        Notices given in connection with this Agreement shall be in writing and
be deemed to have been given when actually received by telecopy or otherwise or
five (5) days after being deposited in the United States mail, postage prepaid,
addressed to a party hereto at the address set forth below such party's
signature to this Agreement, or to such other address designated by such party
by notice to each other party.

        9.       Counterparts.

        This Agreement may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all of which together
shall constitute one and the same instrument.

        10.      Additional Parties.

entities that he now or hereafter controls, directly or indirectly, which

        1.       Amendment of Voting Trust Agreement.  The Voting Trust
Agreement shall hereby be amended by adding the following new paragraphs (c)
and (d) at the end of Section 4 of the Voting Trust Agreement:

                 (c)     Notwithstanding any other provision of this Agreement,
        upon the adoption by the Board of Directors of Dart of a resolution
        setting forth, and declaring the advisability of, an amendment to the
        Certificate of Incorporation of Dart, as amended, to provide the holder
        of each outstanding share of Dart's Class A Common Stock with





                                       4
<PAGE>   5
        the right to vote in the election of directors and all other matters on
        the same basis as the holder of each outstanding share of Dart's Class
        B Common Stock, the Voting Trustee shall be required to vote all of the
        Trust Shares (to the full extent the Trust Shares are entitled to be
        voted) in favor of such amendment, either by written consent of
        majority stockholder in lieu of a meeting pursuant to Section 228 of
        the Delaware General Corporation Law or at a special meeting of
        stockholders called for such purpose, so as to cause such amendment to
        become effective immediately at the time of the HHH Closing (as defined
        in that certain Second Supplemental Settlement Agreement, dated as of
        October 15, 1997, by and between the Beneficiary and Dart).

                 "(d)    Notwithstanding any other provision of this Agreement,
        after an amendment of Dart's Certificate of Incorporation referenced in
        paragraph (c) of this Section 4 has become effective, the Voting
        Trustees shall not be entitled to vote any of the Trust Shares in any
        election of directors or on any other matter, unless all of the Trust
        Shares are voted in the same proportion as the other outstanding shares
        of Dart that are voted in such election or on such matter, so that the
        voting of the Trust Shares in such election or on such matter shall not
        change the outcome."

        2.       Effectiveness.  Dart is hereby authorized to deliver written
notice of this Voting Trust Amendment to Richard B. Stone, as Voting Trustee
under the Voting Trust Agreement.  In accordance with Section 12 of the Voting
Trust Agreement, the amendment of the Voting Trust Agreement set forth in

the earlier of (i) the written acceptance of such amendment by Richard B.
Stone, as Voting Trustee, or (ii) ten (10) days after written notice of this
Voting Trust Amendment is delivered to

<PAGE>   6
Richard B. Stone pursuant to the first sentence of this Section 2.

        3.       Counterparts.  This Voting Trust Amendment may be executed in
any number of counterparts, each of which so executed shall be deemed to be an
original, but all of which together shall constitute one and the same
instrument.

        IN WITNESS WHEREOF, the Beneficiary and Dart have executed this
Amendment, or have caused this Amendment to be executed on their behalf, on the
date first above written.
