                        NOTES TO CONDENSED CONSOLIDATED
                              FINANCIAL STATEMENTS
                                 MARCH 31, 1997
                                  (Unaudited)


1.  BASIS OF PRESENTATION:

These accompanying unaudited Condensed Consolidated Financial Statements
("Financial Statements") have been prepared pursuant to Securities and Exchange
Commission ("SEC") rules and regulations and should be read in conjunction with
the Consolidated Financial Statements and Notes thereto included on Form 10-K
for the year ended December 31, 1996 (the "Annual Report") for American Classic
Voyages Co. ("AMCV") and its subsidiaries. These Financial Statements include
the accounts of AMCV and its wholly owned subsidiaries, The Delta Queen
Steamboat Co. ("DQSC") and Great Hawaiian Cruise Line, Inc. ("GHCL")
(collectively with such subsidiaries, the "Company"). The following notes to the
Financial Statements highlight significant changes to the notes included in the
Annual Report and such interim disclosures as required by the SEC. These
Financial Statements reflect, in the opinion of management, all adjustments
necessary for a fair presentation of the interim financial statements. All such
adjustments are of a normal and recurring nature. Certain previously reported
amounts have been reclassified to conform to the 1997 presentation.

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent liabilities at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates.


2.  RECENT PRONOUNCEMENTS:

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 128, "Earnings Per Share", which
requires dual presentation of basic and fully diluted earnings per share. The
Company will adopt the new standard, as required, in the fourth quarter of
1997. In the interim, the Company will disclose, if material, the pro forma
effect of calculating the Company's earnings per share under the new standard
in the notes to its financial statements. For the quarter ending March 31,
1997, SFAS No. 128 did not have a material impact on the Company's loss per
share calculation.

As of March 31, 1997, the Company was in compliance with all covenants under
its various debt agreements.

4.  IMPAIRMENT WRITE-DOWN:

As discussed more fully in the Company's Annual Report, in the first quarter of
1996, the Company recognized an impairment write-down of $38.4 million related
to its decision not to renovate or return the Constitution to service. The
impairment write-down was recognized in accordance with SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed of", which the Company adopted effective January 1, 1996. SFAS No.
121 establishes accounting standards for recognizing the impairment of
long-lived assets, identifiable intangibles and goodwill, whether to be disposed
of or to be held and used. The Company reserved for the estimated costs to be
incurred on behalf of the Constitution until its eventual disposition. These
costs include insurance, wet berthing fees and general maintenance of the
vessel. As of March 31, 1997, the balance of this reserve was $2.5 million. The
estimated salvage value for the Constitution of $2.5 million is reflected in
property and equipment on the balance sheet.

                          AMERICAN CLASSIC VOYAGES CO.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                           OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS


GENERAL

American Classic Voyages Co. ("AMCV," or along with its subsidiaries, the
"Company"), is a holding company which owns and controls The Delta Queen
Steamboat Co. ("DQSC") and Great Hawaiian Cruise Line, Inc. ("GHCL"). The
following discusses the Company's consolidated results of operations and
financial condition for the first quarter of 1997 as compared to the first
quarter of 1996. This section should be read in conjunction with the
Management's Discussion and Analysis of Financial Condition and Results of
Operations included in the Company's Annual Report for the year ended December
31, 1996.

The Company, through its various subsidiaries, operates two cruise lines:
"Delta Queen", which owns and operates the American Queen, Mississippi Queen
and Delta Queen steamboats, and "American Hawaii", which owns and operates the
Independence steamship. American Hawaii also owns the Constitution steamship
which was removed from service in June 1995 and is currently in wet berth in
Portland, Oregon and will not be returned to service. The Company wrote-down
the value of the vessel to its estimated salvage value effective March 31,
1996. The Company also owned and operated the Maison Dupuy Hotel ("Hotel")
located in New Orleans, prior to its sale in October 1996.

The Company's operations are seasonal. At Delta Queen, historically there is
greater passenger interest at higher yields in the spring and fall months of
the year and the vessels typically undergo an annual lay-up in December and/or
January. American Hawaii historically experiences greater passenger interest in
the summer and fall months of the year. During the summer months, in
particular, American Hawaii tends to have average occupancy in excess of 100%
as the number of families sharing cabins with children increases significantly
during this period.

Results of operations for the first quarter of 1996 include an impairment
write-down as discussed in Note 4 of the Notes to Condensed Consolidated
Financial Statements. In addition, 1996 operating results included the
operations of the Hotel which was sold in October 1996.  American Hawaii is
required to drydock the Independence every 30 months, and as such, the
Independence will be out of service for a four-week period beginning May 17,
1997. As a result of the factors mentioned above, interim results of operations
are not necessarily indicative of results for a full year.


RESULTS OF OPERATIONS

The following tables set forth various financial results and operating
statistics for the three months ended March 31, 1997 and 1996 (certain
previously reported amounts have been reclassified to conform to the 1997
presentation):

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

(1)  Weighted average operating days for each cruise line is determined by
     dividing capacity passenger nights for each cruise line by the cruise
     line's total vessel capacity per day.

(2)  Vessel capacity per day represents the number of passengers each cruise
     line can carry assuming double occupancy for cabins which accommodate two
     or more passengers. Some cabins on the Independence and the American Queen
     can accommodate three or four passengers.

(3)  Capacity passenger nights is determined by multiplying, for the respective
     period, the actual operating days of each vessel by each vessel's capacity
     per day.

(4)  A passenger night represents one passenger spending one night on a vessel;
     for example, one passenger taking a three-night cruise would generate three
     passenger nights.

(5)  Physical occupancy percentage is passenger nights divided by capacity
     passenger nights.

QUARTER ENDED MARCH 31, 1997 COMPARED TO QUARTER ENDED MARCH 31, 1996

Consolidated first quarter 1997 revenues decreased $1.3 million to $40.4
million from $41.6 million for the first quarter 1996 representing a $0.7
million increase in cruise revenues offset by a $1.9 million decrease in Hotel
revenues as a result of the sale of the Hotel in October 1996. Delta Queen's
cruise revenues increased $3.6 million, reflecting an 18% increase in fare
revenue per passenger night ("fare per diems").  The increase in fare per diems
as compared to 1996 was attributable to the shifting of the booking cycle of
when a majority of its cabin inventory is sold to its optimal schedule of six
to nine months in advance. American Hawaii's revenues decreased $2.9 million
mainly due to a 12% decrease in passenger nights with a slight increase in fare
per diems. The consolidated fare per diems increased 8% to $221. Consolidated
total revenue per passenger night increased by 10% to $304 due to the increase
of passengers purchasing travel packages at Delta Queen.  However, the increase
in travel package revenue was largely offset by an increase in related travel
package expenses.

Consolidated cost of operations decreased to $27.1 million for the first
quarter of 1997 from $28.1 million for the comparable period of 1996.  Of the
$28.1 million in 1996, $0.6 million represented Hotel related cost of
operations. American Hawaii's operating costs decreased $1.9 million as a
result of lower variable expenses associated with lower passenger nights. Delta
Queen's operating costs increased $1.6 million primarily due to higher travel
package expenses. Consolidated gross profit for the cruise lines increased $1.0
million as a result of higher revenues at Delta Queen and lower operating
expenses at American Hawaii.

Consolidated selling, general and administrative ("SG&A") expenses decreased to
$11.5 million for the first quarter of 1997 from $13.5 million for the same
period in 1996. Of the $13.5 million in 1996, $0.5 million represented Hotel
related SG&A expenses. Both operating lines realized savings in corporate
overhead expenses as a result of strong cost control measures. Delta Queen's
marketing expenses were approximately 13% lower than the prior year offset
somewhat by a slight increase in American Hawaii's marketing expenses. The $0.2
million increase in depreciation and amortization expense represented a $0.1
million decrease in Hotel related depreciation expense offset by a $0.3 million
increase in cruise depreciation expense.

In the first quarter of 1996, the Company recognized an impairment write-down
of $38.4 million related to its decision not to renovate or return the
Constitution to service. The Company has reserved for the estimated costs to be
incurred on behalf of the Constitution until its eventual disposition. These
costs include insurance, wet berthing fees and general maintenance of the
vessel. As of March 31, 1997, the balance of this reserve was $2.5 million.

Consolidated operating loss for the first quarter of 1997 was $1.9 million as
compared to an operating loss of $3.4 million, excluding the write-down, for
the first quarter of 1996.

Interest expense decreased $0.4 million due to a lower outstanding debt balance
in the first quarter of 1997. The Company's consolidated effective tax rate was
higher in the first quarter of 1997 as compared to the same period in 1996. In
the first quarter of 1996, the Company recognized a valuation allowance for the
full amount of the Federal tax benefit due to the possibility that the deferred
tax asset created may not be realized in the future. The Company subsequently
reviewed its position and in the fourth quarter of 1996 recognized an
adjustment for the full amount of the Federal tax benefit.


LIQUIDITY, CAPITAL RESOURCES AND FINANCIAL CONDITION

Operating Activities

For the three months ended March 31, 1997, cash used in operations before
changes in unearned passenger revenues ("Operating Cash Flow") of $2.9 million
was slightly higher than the $2.3 million used in the prior year due to working
capital changes. Unearned passenger revenues, representing passenger cruise
deposits, increased $5.8 million as of March 31, 1997, reflecting the higher
advance reservation levels at Delta Queen on three boats for the historically
strong spring season and a decrease in American Hawaii's unearned passenger
revenues in anticipation of the upcoming four week out-of-service period
beginning May 17, 1997 for a drydock.

Capital Expenditures

Capital expenditures of $2.5 million in the first quarter of 1997 included $1.9
million related to the Delta Queen, Mississippi Queen and American Queen
lay-ups.

The Independence will be out of service for a four-week period beginning May
17, 1997 for a drydock to comply with U.S. Coast Guard requirements. In
addition, 1997 SOLAS upgrades will be made, as well as passenger area
enhancements and the build-out of approximately 25 new cabins. This drydock is
estimated to cost approximately $12.3 million. In addition, with the Company's
decision to relocate the Chicago operations of American Hawaii to New Orleans,
the current Delta Queen operating facility at Robin Street Wharf will be
expanded and upgraded.  The work will be completed in phases from the middle of
September 1997 through the end of December 1997, at an approximate cost of $3.0
million.

Debt

As of March 31, 1997, the Company was in compliance with all covenants under
its various debt agreements.

The Company believes it will have adequate access to capital resources, both
internally and externally, to meet its short-term and long-term capital
commitments. Such resources may include cash on hand and the ability to secure
additional financing through the capital markets. The Company continually
evaluates opportunities to increase capacity, particularly with regard to the
American Hawaii business. In addition, the Company also evaluates opportunities
to strategically grow its business. If it would elect to increase capacity or
pursue a strategic business opportunity, the Company may seek to secure
additional financing. Notwithstanding, there can be no assurances that the
Company will choose to increase capacity or strategically grow its business,
or, if it elects to do so, that it will obtain additional financing.

Other

The Federal Maritime Commission ("FMC") regulates passenger vessels with 50 or
more berths departing from U.S. ports and requires that operators post security
to be used in the event the operator fails to provide cruise services, or
otherwise satisfy certain financial standards. The Company has been approved as
a self-insurer by the FMC, and therefore, subject to continued approval, is not
required to post security for passenger cruise deposits. In June 1996, the FMC
issued proposed regulations to increase the financial responsibility
requirements. The Company filed its opposition to the proposal, as it believes
that the FMC's current standards provide passengers with adequate protection in
the event of an operator's non-performance and that further requirements may
impose an undue burden on operators. If implemented, these proposed regulations
would be phased in over time and, among other things, require operators
qualifying as a self-insurer, such as the Company, to satisfy a working capital
test, in addition to the existing net worth test, and to provide third-party
coverage for 25% of its unearned passenger revenue in the form of a surety bond
or similar instrument. At this time, the Company cannot predict if the proposed
changes will be approved as currently constituted, or at all. If they are
implemented, the proposed changes would require that the Company establish a
bond to cover a portion of its passenger deposits and payments, which may
impact the Company's liquidity.

Factors Concerning Forward-Looking Statements

Certain statements in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" constitute "forward-looking statements"
within the meaning of the Private Securities Litigation Reform Act of 1995.
Such forward-looking statements involve known and unknown risks, uncertainties
and other factors which may cause the actual results, performance or
achievements of the Company to be materially different from any future results,
performance or achievements expressed or implied by such forward-looking
statements. Such factors include, among others, the following: general economic
and business conditions which may impact passenger yields and occupancy;
weather patterns affecting either the inland waterways in the Continental U.S.
or the Hawaiian Islands; unscheduled repairs and drydocking of the Company's
vessels; construction delays and/or cost overruns during regularly scheduled
lay-ups and/or drydocks; the impact of changes in laws and implementation of
government regulations; an increase in capacity at American Hawaii or pursuit
of a strategic business opportunity; and the ability to obtain additional
financing, if necessary.

                                    AS AGENT


          This Amendment Number 1 (this "Amendment") to the Third Amended and
Restated Credit Agreement dated as of April 22, 1996 among The Delta Queen
Steamboat Co., American Classic Voyages Co., the financial institutions from
time to time parties thereto and The Chase Manhattan Bank (formerly known as

1996.  Capitalized terms used herein but not otherwise defined herein shall have
the respective meanings assigned to such terms in the Credit Agreement.

          1.       The Borrower, the Parent, the Lenders and the Agent have
agreed to amend the Credit Agreement, and accordingly, effective as of November
18, 1996, upon satisfaction of the conditions precedent set forth below and in
reliance upon the representations and warranties set forth herein, the Credit
Agreement is hereby amended as follows:

          1.1      Section 7.03(i) is amended by adding at the end thereof the
following:

                   "; and Investments by the Borrower in commercial paper that
                   would qualify as a Cash Equivalent but for the fact that the
                   issuer's rating on such commercial paper is not at least A-1
                   from S&P of P-1 from Moody's, provided that (i) such rating
                   is at least A-2 from S&P or P-2 from Moody's and (ii) the
                   aggregate amount of such Investments at any time shall not
                   exceed $10,000,000;"

          2.       This Amendment shall become effective as of November 18, 1996

under the Credit Agreement as amended by this Amendment; and (ii) the Agent
shall have received a copy of this Amendment duly executed by the Borrower, the
Parent and the Requisite Lenders, together with the Consent attached hereto
executed by the Borrower Subsidiaries named thereon.

          3.       The Borrower and the Parent hereby represent and warrant that
this Amendment and the Credit Agreement, as amended, constitute legal, valid and
binding obligations of the Borrower and the Parent and are enforceable against
the Borrower and the


<PAGE>   2


Parent in accordance with their respective terms, and that after giving effect
to this Amendment, no Event of Default or Potential Event of Default has
occurred and is continuing.

          4.       Upon the effectiveness of this Amendment, each reference in
the Credit Agreement to "this Agreement," "hereunder," "hereof," "herein," or
words of like import, and each reference in the other Loan Documents to "the
Credit Agreement," "thereunder," "thereof," "therein," or words of like import,
shall mean and be a reference to the Credit Agreement as amended hereby.  Except
as expressly set forth herein, all terms and conditions of the Credit Agreement,
the other Loan Documents and the other documents and agreements executed by the
Borrower or its Affiliates in connection therewith shall remain in full force
and effect and are hereby ratified and confirmed in all respects.

          5.       This Amendment may be executed by the parties hereto on
separate counterparts and each of said counterparts taken together shall be
deemed to constitute one and the same instrument.


          IN WITNESS WHEREOF, this Amendment has been duly executed on the date
set forth above.

     receivable or otherwise distributed in respect of or in exchange for any or
     all of such shares and will promptly thereafter deliver to the Lender, a
     certificate duly executed by the Pledgor describing such percentage
     interests, certificates, units, options or warrants and certifying that the
     same have been duly pledged hereunder;

          (c) The property and interests in property described in Section 3
     below; and

          (d) All proceeds of the foregoing.

          2.  Security for Liabilities.  The Pledged Collateral secures the
prompt payment, performance and observance of (i) the Obligations and (ii) the
Pledgor's obligations and liabilities under this Agreement and each agreement,
document or instrument executed pursuant to or in connection with this Agreement
(all such 

<PAGE>   3

obligations and liabilities of the Pledgor and the Borrower now or hereafter
existing being hereinafter referred to as the "LIABILITIES").

          3.  Pledged Collateral Adjustments.  If, during the term of this
Agreement:

          (a)  Any reclassification, readjustment or other change is declared or
     made in the capital structure of GRCL or of GOCL, or any option included
     within the Pledged Collateral is exercised, or both, or

          (b)  Any subscription, warrants or any other rights or options shall
     be issued in connection with the Pledged Collateral,

then all new, substituted and additional membership interests, certificates,
warrants, rights, options or other securities, issued by reason of any of the
foregoing, shall be immediately delivered to and held by the Agent under the
terms of this Agreement and shall constitute Pledged Collateral hereunder;
provided, however, that nothing contained in this Section 3 shall be deemed to
permit any distribution, issuance of additional membership interests, warrants,
rights or options, reclassification, readjustment or other change in the
capital structure of GRCL or of GOCL which is not expressly permitted in the
Credit Agreement.

          4.  Subsequent Changes Affecting Pledged Collateral. The Pledgor
represents and warrants that it has made its own arrangements for keeping itself
informed of changes or potential changes affecting the Pledged Collateral
(including, but not limited to, rights to convert, rights to subscribe, cash
distributions or other distributions, reorganization or other exchanges, tender
offers and voting rights), and the Pledgor agrees that neither the Agent nor any
of the Holders of Secured Obligations shall have any obligation to inform the
Pledgor of any such changes or potential changes or to take any action or omit
to take any action with respect thereto.  The Agent may, after the occurrence of
an Event of Default, without notice and at its option, transfer or register the
Pledged Collateral or any part thereof into its or its nominee's name with or
without any indication that such Pledged Collateral is subject to the security
interest hereunder.  In addition, the Agent may at any time exchange
certificates or instruments representing or evidencing Pledged Membership
Interests for certificates or instruments of smaller or larger denominations.


          5.  Representations and Warranties.  The Pledgor represents and
warrants as follows:

          (a)  The Pledgor is the sole legal and beneficial owner of the
     membership interests in GRCL and in GOCL pledged to the Agent pursuant to
     this Agreement, free and clear of any Lien except for the security interest
     created by this Agreement;

          (b)  This Agreement has been duly and validly authorized, executed and
     delivered by Pledgor and constitutes the legal, valid and binding
     obligation of the Pledgor enforceable against the Pledgor in accordance
     with its terms except as enforcement may be limited by bankruptcy,
     insolvency and other similar laws affecting the enforcement of creditors'
     rights generally and by moratorium laws from time to time in effect and
     general equitable principles;

<PAGE>   4


          (c)     Such Pledgor is the direct beneficial owner of the Pledged
     Collateral hereby pledged by it;

          (d)     The Pledgor owns such Pledged Collateral free and clear of any
     Lien, except for the pledge and security interest granted to the Agent and
     the Holders of Secured Obligations hereunder;

          (e)     The Pledgor shall cause GRCL and GOCL to make a notation on
     their respective records, which notation shall indicate the security
     interest granted hereby, and such Pledgor agrees to execute and file
     financing statements pursuant to the Uniform Commercial Code as the Agent
     may request to perfect the security interest granted hereby, and such
     Pledgor agrees to execute and deliver to GRCL and to GOCL a Pledge
     Instruction in the form of Exhibit B hereto;

          (f)     The pledge of the Pledged Collateral by the Pledgor does not
     violate (1) the Operating Agreements of GRCL or of GOCL or any of the other
     organizational documents of GRCL or of GOCL; (2) the certificate of
     incorporation or by-laws of the Pledgor; (3) any indenture, mortgage, loan
     or credit agreement to which the Pledgor, GRCL or GOCL is a party or by
     which any of their respective properties or assets may be bound; or (4) any
     restriction on such transfer or encumbrance of such Pledged Collateral;

          (g)  Except as set forth in the Operating Agreements, there are no
     restrictions upon the voting rights associated with, or upon the transfer
     of, any of the Pledged Collateral;

          (h)  Except as set forth in the Operating Agreements, the Pledgor has
     the right to vote, pledge, assign and grant a security interest in or
     otherwise transfer such Pledged Collateral free of any Liens;

          (i)  No authorization, approval, or other action by, and no notice to
     or filing with, any governmental authority or regulatory body is required
     either (i) for the pledge of the Pledged Collateral pursuant to this
     Agreement or for the execution, delivery or performance of this Agreement
     by the Pledgor or (ii) for the exercise by the Agent of the voting or other
     rights provided for in this Agreement or the remedies in respect of the
     Pledged Collateral pursuant to this Agreement (except as may be required in
     connection with such disposition by laws affecting the offering and sale of
     securities generally);

          (j)  The pledge of the Pledged Collateral pursuant to this Agreement
     creates a valid and perfected first priority security interest in the
     Pledged Collateral, in favor of the Agent for the benefit of the Agent and
     the Holders of Secured Obligations, securing the payment and performance of
     the Liabilities;

          (k)  The pledge of the Pledge Collateral pursuant to this Agreement
     constitutes a complete assignment of the Pledged Collateral pursuant to 6
     Del. Code Ann. Section  18-702 (1996).

<PAGE>   5


          6.  Voting Rights and Other Powers.  During the term of this
Agreement, and except as provided in this Section 6 below, the Pledgor shall
have (i) the right to vote the Pledged Membership Interest on all questions in a
manner not inconsistent with the terms of this Agreement, the Credit Agreement
and any other agreement, instrument or document executed pursuant thereto or in
connection therewith, and (ii) the right to be the member and manager of GRCL
and/or GOCL, and shall be entitled to exercise all managerial, election and
other rights relating to the Pledged Collateral.  After the occurrence or during
the continuance of an Event of Default, the Agent or the Agent's nominee may, at
the Agent's or such nominee's option and following written notice ("ELECTION
NOTICE") from the Agent to the Pledgor (x) exercise, or direct such Pledgor as
to the exercise of (whereupon such Pledgor shall exercise as so directed), all
voting, consent, managerial, election and other membership and manager rights to
the Pledged Collateral of the Pledgor; such authorization shall constitute an
irrevocable voting proxy from the Pledgor to the Agent or, at the Agent's
option, to the Agent's nominee; and (y) exercise, or direct such Pledgor as to
the exercise of (whereupon the Pledgor shall exercise as so directed), any and
all rights of conversion, exchange, subscription or any other rights, privileges
or options pertaining to the Pledged Collateral of the Pledgor as if the Agent
were the absolute owner thereof, all without liability except to account for
property actually received by it, but the Agent shall have no duty to exercise
any of the aforesaid rights, privileges or options and shall not be responsible
for any failure so to do or delay in so doing.  Under no circumstances shall the
Agent have, or be deemed to have or to have had, any right to exercise, or to
direct the Pledgor to exercise, any voting, managerial, election or other rights
of an owner of the Pledged Collateral, or arising under the Pledged Collateral,
unless and until the Agent shall have delivered to such Pledgor an Election
Notice as described hereinabove.

          7.  Cash and Other Distributions.  (a) So long as no Event of Default
or Potential Event of Default shall have occurred and be continuing:

          (i)  The Pledgor shall be entitled to receive and retain any and all
     cash distributions and interest paid in respect of the Pledged Collateral
     (including a distribution of net cash flow) to the extent such
     distributions are not prohibited by the Credit Agreement, provided,
     however, that any and all

               (A)  distributions and interest paid or payable other than in
          cash with respect to, and instruments and other property received,
          receivable or otherwise distributed with respect to, or in exchange
          for, any of the Pledged Collateral;

               (B)  other distributions paid or payable in cash with respect to
          any of the Pledged Collateral on account of a partial or total
          liquidation or dissolution or in connection with a reduction of
          capital, capital surplus or paid-in surplus; and

               (C)  cash paid, payable or otherwise distributed with respect to
          principal of, or in redemption of, or in exchange for, any of the
          Pledged Collateral;

     shall be Pledged Collateral, and shall be forthwith delivered to the Agent
     to hold, for the benefit of the Agent and the Holders of Secured
     Obligations, as Pledged 

<PAGE>   6

          Collateral and shall, if received by the Pledgor, be received in trust
          for the Agent, for the benefit of the Agent and the Holders of Secured
          Obligations, be segregated from the other property or funds of the
          Pledgor, and be delivered immediately to the Agent as Pledged
          Collateral in the same form as so received (with any necessary
          endorsement); and

               (ii)  The Agent shall execute and deliver (or cause to be
          executed and delivered) to the Pledgor all such proxies and other
          instruments as the Pledgor may reasonably request for the purpose of
          enabling the Pledgor to receive the distributions or interest payments
          which it is authorized to receive and retain pursuant to clause (i)
          above.

          (b) After the occurrence and during the continuance of an Event of
     Default or Potential Event of Default:

               (i)  All rights of the Pledgor to receive the distributions and
          interest payments which it would otherwise be authorized to receive
          and retain pursuant to Section 7(a)(i) hereof shall cease, and all
          such rights shall thereupon become vested in the Agent, for the
          benefit of the Agent and the Holders of Secured Obligations, which
          shall thereupon have the sole right to receive and hold as Pledged
          Collateral such distributions and interest payments;

               (ii)  All distributions and interest payments which are received
          by the Pledgor contrary to the provisions of clause (i) of this
          Section 7(b) shall be received in trust for the Agent, for the benefit
          of the Agent and the Holders of Secured Obligations, shall be
          segregated from other funds of the Pledgor and shall be paid over
          immediately to the Agent as Pledged Collateral in the same form as so
          received (with any necessary endorsements).

          (c)  All sums of money that are delivered to the Agent pursuant to
     this Section 7 shall be deposited into an interest bearing account with the
     Agent (the "CASH COLLATERAL ACCOUNT").  Some or all of the funds from time
     to time in the Cash Collateral Account may be invested in time deposits,
     including, without limitation, certificates of deposit issued by the Agent
     (such certificates of deposit or other time deposits being hereinafter
     referred to, collectively, as "TIME DEPOSITS"), that are satisfactory to
     the Agent after consultation with the Pledgor.  Interest earned on the Cash
     Collateral Account and on the Time Deposits, and the principal of the Time
     Deposits at maturity that is not invested in new Time Deposits, shall be
     deposited in the Cash Collateral Account.  The Cash Collateral Account, all
     sums from time to time standing to the credit of the Cash Collateral
     Account, any and all Time Deposits, any and all instruments or other
     writings evidencing Time Deposits and any and all proceeds of any thereof
     are hereinafter referred to as the "Cash Collateral" and shall constitute
     Pledged Collateral hereunder. Except as otherwise expressly provided in
     Section 13, the Pledgor shall have no right to withdraw sums from the Cash
     Collateral Account, to receive any of the Cash Collateral or to require the
     agent to part with the Agent's possession of any instruments or other
     writings evidencing any Time Deposits.

          8.  Transfers and Other Liens.  The Pledgor agrees that it will not
(i) sell or otherwise dispose of, or grant any option with respect to, any of
the Pledged Collateral without the prior written consent of the Agent, or (ii)
create or permit to exist 

<PAGE>   7

any Lien upon or with respect to any of the Pledged Collateral, except for the
security interest under this Agreement.  To the extent additional or different
members of GRCL or of GOCL are permitted, Pledgor shall cause as a condition to
permitting such entity to become a member that the new member consent to (i) the
terms of this Agreement; (ii) the Pledge and assignment of the Pledged
Collateral; and (ii) the rights granted hereunder for the Agent to become the/a
member of GRCL or of GOCL at its election.

          9.  Remedies.  (a)  The Agent shall have, in addition to any other
rights given under this Agreement or by law, all of the rights and remedies with
respect to the Pledged Collateral of a secured party under the Uniform
Commercial Code as in effect in the State of New York.  After the occurrence and
during the continuance of an Event of Default and following written notice to
the Pledgor, the Agent (personally or through an agent) is hereby authorized and
empowered to transfer and register in its name or in the name of its nominee the
whole or any part of the Pledged Collateral, to exercise all voting rights with
respect thereto, to collect and receive all cash distributions and other
distributions made thereon, and to otherwise act with respect to the Pledged
Collateral as though the Agent were the outright owner thereof and the sole
member and manager of GRCL and of GOCL, the Pledgor hereby irrevocably
constituting and appointing the Agent as the proxy and attorney-in-fact of the
Pledgor, with full power of substitution to do so, such proxy becoming effective
upon the occurrence of an Event of Default and following written notice thereof;
provided, however, that the Agent shall have no duty to exercise any such right
or to preserve the same and shall not be liable for any failure to do so or for
any delay in doing so.  In addition, after the occurrence of an Event of
Default, the Agent shall have such powers of sale and other powers as may be
conferred by applicable law.  With respect to the Pledged Collateral or any part
thereof which shall then be in or shall thereafter come into the possession or
custody of the Agent or which the Agent shall otherwise have the ability to
transfer under applicable law, the Agent may, in its sole discretion, without
notice except as specified below, after the occurrence of an Event of Default,
sell or cause the same to be sold at any exchange, broker's board or at public
or private sale, in one or more sales or lots, at such price as the Agent may
deem best, for cash or on credit or for future delivery, without assumption of
any credit risk, and the purchaser of any or all of the Pledged Collateral so
sold shall thereafter own the same, absolutely free from any claim, encumbrance
or right of any kind whatsoever.  The Agent and each of the Holders of Secured
Obligations may, in its own name, or in the name of a designee or nominee, buy
the Pledged Collateral at any public sale and, if permitted by applicable law,
buy the Pledged Collateral at any private sale.  The Pledgor will pay to the
Agent all reasonable expenses (including, without limitation, court costs and
reasonable attorneys' and paralegals' fees and expenses) of, or incidental to,
the enforcement of any of the provisions hereof.  The Agent agrees to distribute
any proceeds of the sale of the Pledged Collateral in accordance with the Credit
Agreement and the Pledgor shall remain liable for any deficiency following the
sale of the Pledged Collateral.

          (b)  Unless any of the Pledged Collateral threatens to decline
speedily in value or is or becomes of a type sold on a recognized market, the
Agent will give the Pledgor reasonable notice of the time and place of any
public sale thereof, or of the time after which any private sale or other
intended disposition is to be made.  Any sale of the Pledged Collateral
conducted in conformity with reasonable commercial practices of banks,
commercial finance companies, insurance companies or other financial
institutions disposing of property similar to the Pledged Collateral shall be
deemed to be 

<PAGE>   8

commercially reasonable.  Notwithstanding any provision to the contrary
contained herein, the Pledgor agrees that any requirements of reasonable notice
shall be met if such notice is received by the Pledgor as provided in Section 25
below at least ten (10) Business Days before the time of the sale or
disposition; provided, however, that Agent may give any shorter notice that is
commercially reasonable under the circumstances.  Any other requirement of
notice, demand or advertisement for sale is waived, to the extent permitted by
law.

          (c)  In view of the fact that federal and state securities laws may
impose certain restrictions on the method by which a sale of the Pledged
Collateral may be effected after a Default, the Pledgor agrees that after the
occurrence of an Event of Default, the Agent may, from time to time, attempt to
sell all or any part of the Pledged Collateral by means of a private placement
restricting the bidders and prospective purchasers to those who are qualified
and will represent and agree that they are purchasing for investment only and
not for distribution.  In so doing, the Agent may solicit offers to buy the
Pledged Collateral, or any part of it, from a limited number of investors deemed
by the Agent, in its reasonable judgment, to be financially responsible parties
who might be interested in purchasing the Pledged Collateral.  If the Agent
solicits such offers from not less than four (4) such investors, then the
acceptance by the Agent of the highest offer obtained therefrom shall be deemed
to be a commercially reasonable method of disposing of such Pledged Collateral;
provided, however, that this Section does not impose a requirement that the
Agent solicit offers from four or more investors in order for the sale to be
commercially reasonable.

          10.  Security Interest Absolute.  All rights of the Agent and security
interests hereunder, and all obligations of the Pledgor hereunder, shall be
absolute and unconditional irrespective of:

          (i)  Any lack of validity or enforceability of the Credit Agreement or
     any other agreement or instrument relating thereto;

          (ii)  Any change in the time, manner or place of payment of, or in any
     other term of, all or any part of the Liabilities, or any other amendment
     or waiver of or any consent to any departure from the Credit Agreement;

          (iii)  Any exchange, release or non-perfection of any other
     collateral, or any release or amendment or waiver of or consent to
     departure from any guaranty, for all or any part of the Liabilities; or

          (iv)  any other circumstance which might otherwise constitute a
     defense available to, or a discharge of, the Pledgor in respect of the
     Liabilities or of this Agreement.

          11.  Agent Appointed Attorney-in-Fact.  The Pledgor hereby appoints
the Agent its attorney-in-fact, with full authority, in the name of the Pledgor
or otherwise, after the occurrence and during the continuation of an Event of
Default, from time to time in the Agent's sole discretion, to take any action
and to execute any instrument which the Agent may deem necessary or advisable to
accomplish the purposes of this Agreement, including, without limitation, to
receive, endorse and collect all instruments made payable to the Pledgor
representing any cash distribution, interest payment or 

<PAGE>   9

other distribution in respect of the Pledged Collateral or any part thereof and
to give full discharge for the same, to exercise all rights of a member and
manager (upon the election of the Agent) such as all voting, consent, managerial
and other member rights, and to arrange for the transfer of all or any part of
the Pledged Collateral on the books of GRCL and of GOCL to the name of the Agent
or the Agent's nominee.

          12.  Waivers; Marshalling.  (a)  The Pledgor waives presentment and
demand for payment of any of the Liabilities, protest and notice of dishonor or
default with respect to any of the Liabilities and all other notices to which
the Pledgor might otherwise be entitled except as otherwise expressly provided
herein or in the Credit Agreement.

          (b)  Neither the Agent nor any Holder of Secured Obligations shall be
required to marshall any present or future collateral security for (including
but not limited to this Agreement and the Pledged Collateral), or other
assurances of payment of, the Obligations or any of them, or to resort to such
collateral security or other assurances of payment in any particular order.  All
of the Agent's rights hereunder and of the Holders of Secured Obligations and
the Agent in respect of such collateral security and other assurances of payment
shall be cumulative and in addition to all other rights, however existing or
arising.  To the extent that it lawfully may, the Pledgor hereby agrees that it
will not invoke any law relating to the marshalling of collateral that might
cause delay in or impede the enforcement of the Agent's rights under this
Agreement or under any other instrument evidencing any of the Obligations or
under which any of the Obligations is outstanding or by which any of the
Obligations is secured or payment thereof is otherwise assured, and to the
extent that it lawfully may, the Pledgor hereby irrevocably waives the benefits
of all such laws.

          13.  Term.  This Agreement shall remain in full force and effect until
the Liabilities (other than continuing indemnity obligations) have been fully
and indefeasibly paid in cash and the Credit Agreement has terminated pursuant
to its terms.  Upon the termination of this Agreement as provided above (other
than as a result of the sale of the Pledged Collateral), the Agent will release
the security interest created hereunder and, if it then has possession of the
Pledged Membership Interest or other Pledged Collateral, will deliver the
Pledged Membership Interest and the Powers or such other Pledged Collateral to
the Pledgor.

          14.  Definitions.  The singular shall include the plural and vice
versa and any gender shall include any other gender as the context may require.

          15.  Successors and Assigns.  This Agreement shall be binding upon and
inure to the benefit of the Pledgor, the Agent, for the benefit of itself and
the Holders of Secured Obligations, and their respective successors and assigns.
The Pledgor's successors and assigns shall include, without limitation, a
receiver, trustee or debtor-in-possession of or for the Pledgor.

          16.  GOVERNING LAW.  THE AGENT HEREBY ACCEPTS THIS AGREEMENT, ON
BEHALF OF ITSELF AND THE HOLDERS OF SECURED OBLIGATIONS, AT NEW YORK, NEW YORK
BY ACKNOWLEDGING AND AGREEING TO IT THERE.  ANY DISPUTE BETWEEN THE AGENT OR ANY
HOLDER OF SECURED OBLIGATIONS AND THE PLEDGOR ARISING OUT OF OR RELATED TO THE
RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT, AND 

<PAGE>   10

WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE RESOLVED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

          17.  Consent to Jurisdiction; Counterclaims; Forum Non Conveniens.
(a) Exclusive Jurisdiction.  Except as provided in subsection (b) of this
Section 17, the Agent, on behalf of itself and the Holders of Secured
Obligations, and the Pledgor agree that all disputes between them arising out of
or related to the relationship established between them in connection with this
Agreement, whether arising in contract, tort, equity, or otherwise, shall be
resolved only by state or federal courts located in New York, New York, but the
parties acknowledge that any appeals from those courts may have to be heard by a
court located outside of New York, New York.

          (b)  Other Jurisdictions.  The Agent shall have the right to proceed
against the Pledgor or its real or personal property in a court in any location
to enable the Agent to obtain personal jurisdiction over the Pledgor, to realize
on the Pledged Collateral or any other security for the Liabilities or to
enforce a judgment or other court order entered in favor of the Agent. The
Pledgor shall not assert any permissive counterclaims in any proceeding brought
by the Agent arising out of or relating to this Agreement.

          (c)  Venue; Forum Non Conveniens.  Each of the Pledgor and the Agent
waives any objection that it may have (including, without limitation, any
objection to the laying of venue or based on forum non conveniens) to the
location of the court in which any proceeding is commenced in accordance with
this Section 17.

          18.  Service of Process.  The Pledgor waives personal service of any
process upon it and, as security for the Liabilities, irrevocably appoints The
Prentice Hall Corporation System, Inc., 1013 Centre Road, Wilmington, Delaware
19805, as its registered agent for the purpose of accepting service of process
issued by any court.

          19.  WAIVER OF JURY TRIAL.  EACH OF THE PLEDGOR AND THE AGENT WAIVES
ANY RIGHT TO TRIAL BY JURY IN ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT,
OR OTHERWISE, BETWEEN THE AGENT AND THE PLEDGOR ARISING OUT OF OR RELATED TO THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR
AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH.  EITHER THE PLEDGOR OR
THE AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS AGREEMENT WITH ANY
COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF
THEIR RIGHT TO TRIAL BY JURY.

          20.  Waiver of Bond.  The Pledgor waives the posting of any bond
otherwise required of the Agent in connection with any judicial process or
proceeding to realize on the Pledged Collateral or any other security for the
Liabilities, to enforce any judgment or other court order entered in favor of
the Agent, or to enforce by specific performance, temporary restraining order,
or preliminary or permanent injunction, this Agreement or any other agreement or
document between the Agent and the Pledgor.

          21.  Advice of Counsel.  The Pledgor represents and warrants to the
Agent and the Holders of Secured Obligations that it has consulted with its
legal counsel regarding all waivers under this Agreement, including without
limitation those under Section 12 and Sections 16 through 20 hereof, that it
believes that it fully understands 

<PAGE>   11

all rights that it is waiving and the effect of such waivers, that it assumes
the risk of any misunderstanding that it may have regarding any of the
foregoing, and that it intends that such waivers shall be a material inducement
to the Agent and the Holders of Secured Obligations to extend the indebtedness
secured hereby.

          22.  Severability.  Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but, if any provision of this Agreement shall be held to be
prohibited or invalid under applicable law, such provision shall be ineffective
only to the extent of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this Agreement.

          23.  Further Assurances.  The Pledgor agrees that it will cooperate
with the Agent and will execute and deliver, or cause to be executed and
delivered, all such other stock powers, proxies, instruments and documents, and
will take all such other actions, including, without limitation, the execution
and filing of financing statements, as the Agent may reasonably request from
time to time in order to carry out the provisions and purposes of this
Agreement.

          24.  The Agent's Duty of Care.  The Agent shall not be liable for any

priority security interest in the Pledged Collateral (as hereinafter defined).

          ACCORDINGLY, for and in consideration of the foregoing and of any
financial accommodations or extensions of credit (including, without limitation,
any loan or advance by renewal, refinancing or extension of the agreements
described hereinabove or otherwise) heretofore, now or hereafter made to or for

sufficiency of which are hereby acknowledged, the Pledgor and the Agent hereby
agree as follows:

     other organizational documents (such documents hereinafter collectively
     referred to as the "OPERATING AGREEMENTS") of GRCL or of GOCL, or at law or

     interests, certificates, units, options or warrants and certifying that the
     same have been duly pledged hereunder;

          (c) The property and interests in property described in Section 3
     below; and

          (d) All proceeds of the foregoing.

<PAGE>   3


          2.  Security for Liabilities.  The Pledged Collateral secures the
prompt payment, performance and observance of (i) the Obligations and (ii) the
Pledgor's obligations and liabilities under this Agreement and each agreement,
document or instrument executed pursuant to or in connection with this Agreement
(all such obligations and liabilities of the Pledgor and the Borrower now or
hereafter existing being hereinafter referred to as the "LIABILITIES").

          3.  Pledged Collateral Adjustments.  If, during the term of this
Agreement:

          (a)  Any reclassification, readjustment or other change is declared or
     made in the capital structure of GRCL or of GOCL, or any option included
     within the Pledged Collateral is exercised, or both, or

          (b)  Any subscription, warrants or any other rights or options shall
     be issued in connection with the Pledged Collateral,

then all new, substituted and additional membership interests, certificates,
warrants, rights, options or other securities, issued by reason of any of the
foregoing, shall be immediately delivered to and held by the Agent under the
terms of this Agreement and shall constitute Pledged Collateral hereunder;
provided, however, that nothing contained in this Section 3 shall be deemed to
permit any distribution, issuance of additional membership interests, warrants,
rights or options, reclassification, readjustment or other change in the capital
structure of GRCL or of GOCL which is not expressly permitted in the Credit
Agreement.

          4.  Subsequent Changes Affecting Pledged Collateral. The Pledgor
represents and warrants that it has made its own arrangements for keeping itself
informed of changes or potential changes affecting the Pledged Collateral
(including, but not limited to, rights to convert, rights to subscribe, cash
distributions or other distributions, reorganization or other exchanges, tender
offers and voting rights), and the Pledgor agrees that neither the Agent nor any
of the Holders of Secured Obligations shall have any obligation to inform the
Pledgor of any such changes or potential changes or to take any action or omit
to take any action with respect thereto.  The Agent may, after the occurrence of
an Event of Default, without notice and at its option, transfer or register the
Pledged Collateral or any part thereof into its or its nominee's name with or
without any indication that such Pledged Collateral is subject to the security
interest hereunder.  In addition, the Agent may at any time exchange
certificates or instruments representing or evidencing Pledged Membership
Interests for certificates or instruments of smaller or larger denominations.

          5.  Representations and Warranties.  The Pledgor represents and
warrants as follows:

          (a)  The Pledgor is the sole legal and beneficial owner of the
     membership interests in GRCL and in GOCL pledged to the Agent pursuant to
     this Agreement, free and clear of any Lien except for the security interest
     created by this Agreement;

<PAGE>   4


          (b)  This Agreement has been duly and validly authorized, executed and
     delivered by Pledgor and constitutes the legal, valid and binding
     obligation of the Pledgor enforceable against the Pledgor in accordance
     with its terms except as enforcement may be limited by bankruptcy,
     insolvency and other similar laws affecting the enforcement of creditors'
     rights generally and by moratorium laws from time to time in effect and
     general equitable principles;

          (c)     Such Pledgor is the direct beneficial owner of the Pledged
     Collateral hereby pledged by it;

          (d)     The Pledgor owns such Pledged Collateral free and clear of any
     Lien, except for the pledge and security interest granted to the Agent and
     the Holders of Secured Obligations hereunder;

          (e)     The Pledgor shall cause GRCL and GOCL to make a notation on
     their respective records, which notation shall indicate the security
     interest granted hereby, and such Pledgor agrees to execute and file
     financing statements pursuant to the Uniform Commercial Code as the Agent
     may request to perfect the security interest granted hereby, and such
     Pledgor agrees to execute and deliver to GRCL and to GOCL a Pledge
     Instruction in the form of Exhibit B hereto;

          (f)     The pledge of the Pledged Collateral by the Pledgor does not
     violate (1) the Operating Agreements of GRCL or of GOCL or any of the other
     organizational documents of GRCL or of GOCL; (2) the certificate of
     incorporation or by-laws of the Pledgor; (3) any indenture, mortgage, loan
     or credit agreement to which the Pledgor, GRCL or GOCL is a party or by
     which any of their respective properties or assets may be bound; or (4) any
     restriction on such transfer or encumbrance of such Pledged Collateral;

          (g)  Except as set forth in the Operating Agreements, there are no
     restrictions upon the voting rights associated with, or upon the transfer
     of, any of the Pledged Collateral;

          (h)  Except as set forth in the Operating Agreements, the Pledgor has
     the right to vote, pledge, assign and grant a security interest in or
     otherwise transfer such Pledged Collateral free of any Liens;

          (i)  No authorization, approval, or other action by, and no notice to
     or filing with, any governmental authority or regulatory body is required
     either (i) for the pledge of the Pledged Collateral pursuant to this
     Agreement or for the execution, delivery or performance of this Agreement
     by the Pledgor or (ii) for the exercise by the Agent of the voting or other
     rights provided for in this Agreement or the remedies in respect of the
     Pledged Collateral pursuant to this Agreement (except as may be required in
     connection with such disposition by laws affecting the offering and sale of
     securities generally);

          (j)  The pledge of the Pledged Collateral pursuant to this Agreement
     creates a valid and perfected first priority security interest in the
     Pledged


<PAGE>   5

     Collateral, in favor of the Agent for the benefit of the Agent and the
     Holders of Secured Obligations, securing the payment and performance of the
     Liabilities;

          (k)  The pledge of the Pledge Collateral pursuant to this Agreement
     constitutes a complete assignment of the Pledged Collateral pursuant to 6
     Del. Code Ann. Section  18-702 (1996).

          6.  Voting Rights and Other Powers.  During the term of this
Agreement, and except as provided in this Section 6 below, the Pledgor shall
have (i) the right to vote the Pledged Membership Interest on all questions in a
manner not inconsistent with the terms of this Agreement, the Credit Agreement
and any other agreement, instrument or document executed pursuant thereto or in
connection therewith, and (ii) the right to be the member and manager of GRCL
and/or GOCL, and shall be entitled to exercise all managerial, election and
other rights relating to the Pledged Collateral. After the occurrence or during
the continuance of an Event of Default, the Agent or the Agent's nominee may, at
the Agent's or such nominee's option and following written notice ("ELECTION
NOTICE") from the Agent to the Pledgor (x) exercise, or direct such Pledgor as
to the exercise of (whereupon such Pledgor shall exercise as so directed), all
voting, consent, managerial, election and other membership and manager rights to
the Pledged Collateral of the Pledgor; such authorization shall constitute an
irrevocable voting proxy from the Pledgor to the Agent or, at the Agent's
option, to the Agent's nominee; and (y) exercise, or direct such Pledgor as to
the exercise of (whereupon the Pledgor shall exercise as so directed), any and
all rights of conversion, exchange, subscription or any other rights, privileges
or options pertaining to the Pledged Collateral of the Pledgor as if the Agent
were the absolute owner thereof, all without liability except to account for
property actually received by it, but the Agent shall have no duty to exercise
any of the aforesaid rights, privileges or options and shall not be responsible
for any failure so to do or delay in so doing.  Under no circumstances shall the
Agent have, or be deemed to have or to have had, any right to exercise, or to
direct the Pledgor to exercise, any voting, managerial, election or other rights
of an owner of the Pledged Collateral, or arising under the Pledged Collateral,
unless and until the Agent shall have delivered to such Pledgor an Election
Notice as described hereinabove.

          7.  Cash and Other Distributions.  (a) So long as no Event of Default
or Potential Event of Default shall have occurred and be continuing:

          (i)  The Pledgor shall be entitled to receive and retain any and all
     cash distributions and interest paid in respect of the Pledged Collateral
     (including a distribution of net cash flow) to the extent such
     distributions are not prohibited by the Credit Agreement, provided,
     however, that any and all

               (A)  distributions and interest paid or payable other than in
          cash with respect to, and instruments and other property received,
          receivable or otherwise distributed with respect to, or in exchange
          for, any of the Pledged Collateral;

               (B)  other distributions paid or payable in cash with respect to
          any of the Pledged Collateral on account of a partial or total
          liquidation or 

<PAGE>   6

          dissolution or in connection with a reduction of capital, capital
          surplus or paid-in surplus; and

               (C)  cash paid, payable or otherwise distributed with respect to
          principal of, or in redemption of, or in exchange for, any of the
          Pledged Collateral;

     shall be Pledged Collateral, and shall be forthwith delivered to the Agent
     to hold, for the benefit of the Agent and the Holders of Secured
     Obligations, as Pledged Collateral and shall, if received by the Pledgor,
     be received in trust for the Agent, for the benefit of the Agent and the
     Holders of Secured Obligations, be segregated from the other property or
     funds of the Pledgor, and be delivered immediately to the Agent as Pledged
     Collateral in the same form as so received (with any necessary
     endorsement); and

          (ii)  The Agent shall execute and deliver (or cause to be executed and
     delivered) to the Pledgor all such proxies and other instruments as the
     Pledgor may reasonably request for the purpose of enabling the Pledgor to
     receive the distributions or interest payments which it is authorized to
     receive and retain pursuant to clause (i) above.

     (b) After the occurrence and during the continuance of an Event of Default
or Potential Event of Default:

          (i)  All rights of the Pledgor to receive the distributions and
     interest payments which it would otherwise be authorized to receive and
     retain pursuant to Section 7(a)(i) hereof shall cease, and all such rights
     shall thereupon become vested in the Agent, for the benefit of the Agent
     and the Holders of Secured Obligations, which shall thereupon have the sole
     right to receive and hold as Pledged Collateral such distributions and
     interest payments;

          (ii)  All distributions and interest payments which are received by
     the Pledgor contrary to the provisions of clause (i) of this Section 7(b)
     shall be received in trust for the Agent, for the benefit of the Agent and
     the Holders of Secured Obligations, shall be segregated from other funds of
     the Pledgor and shall be paid over immediately to the Agent as Pledged
     Collateral in the same form as so received (with any necessary
     endorsements).

     (c)  All sums of money that are delivered to the Agent pursuant to this
Section 7 shall be deposited into an interest bearing account with the Agent
(the "CASH COLLATERAL ACCOUNT").  Some or all of the funds from time to time in
the Cash Collateral Account may be invested in time deposits, including, without
limitation, certificates of deposit issued by the Agent (such certificates of
deposit or other time deposits being hereinafter referred to, collectively, as
"TIME DEPOSITS"), that are satisfactory to the Agent after consultation with the
Pledgor.  Interest earned on the Cash Collateral Account and on the Time
Deposits, and the principal of the Time Deposits at maturity that is not
invested in new Time Deposits, shall be deposited in the Cash Collateral
Account.  The Cash Collateral Account, all sums from time to time standing to
the credit of the Cash 

<PAGE>   7

Collateral Account, any and all Time Deposits, any and all instruments or other
writings evidencing Time Deposits and any and all proceeds of any thereof are
hereinafter referred to as the "Cash Collateral" and shall constitute Pledged
Collateral hereunder.  Except as otherwise expressly provided in Section 13, the
Pledgor shall have no right to withdraw sums from the Cash Collateral Account,
to receive any of the Cash Collateral or to require the agent to part with the
Agent's possession of any instruments or other writings evidencing any Time
Deposits.

          8.  Transfers and Other Liens.  The Pledgor agrees that it will not
(i) sell or otherwise dispose of, or grant any option with respect to, any of
the Pledged Collateral without the prior written consent of the Agent, or (ii)
create or permit to exist any Lien upon or with respect to any of the Pledged
Collateral, except for the security interest under this Agreement.  To the
extent additional or different members of GRCL or of GOCL are permitted, Pledgor
shall cause as a condition to permitting such entity to become a member that the
new member consent to (i) the terms of this Agreement; (ii) the Pledge and
assignment of the Pledged Collateral; and (ii) the rights granted hereunder for
the Agent to become the/a member of GRCL or of GOCL at its election.

          9.  Remedies.  (a)  The Agent shall have, in addition to any other
rights given under this Agreement or by law, all of the rights and remedies with
respect to the Pledged Collateral of a secured party under the Uniform
Commercial Code as in effect in the State of New York.  After the occurrence and
during the continuance of an Event of Default and following written notice to
the Pledgor, the Agent (personally or through an agent) is hereby authorized and
empowered to transfer and register in its name or in the name of its nominee the
whole or any part of the Pledged Collateral, to exercise all voting rights with
respect thereto, to collect and receive all cash distributions and other
distributions made thereon, and to otherwise act with respect to the Pledged
Collateral as though the Agent were the outright owner thereof and the sole
member and manager of GRCL and of GOCL, the Pledgor hereby irrevocably
constituting and appointing the Agent as the proxy and attorney-in-fact of the
Pledgor, with full power of substitution to do so, such proxy becoming effective
upon the occurrence of an Event of Default and following written notice thereof;
provided, however, that the Agent shall have no duty to exercise any such right
or to preserve the same and shall not be liable for any failure to do so or for
any delay in doing so.  In addition, after the occurrence of an Event of
Default, the Agent shall have such powers of sale and other powers as may be
conferred by applicable law.  With respect to the Pledged Collateral or any part
thereof which shall then be in or shall thereafter come into the possession or
custody of the Agent or which the Agent shall otherwise have the ability to
transfer under applicable law, the Agent may, in its sole discretion, without
notice except as specified below, after the occurrence of an Event of Default,
sell or cause the same to be sold at any exchange, broker's board or at public
or private sale, in one or more sales or lots, at such price as the Agent may
deem best, for cash or on credit or for future delivery, without assumption of
any credit risk, and the purchaser of any or all of the Pledged Collateral so
sold shall thereafter own the same, absolutely free from any claim, encumbrance
or right of any kind whatsoever. The Agent and each of the Holders of Secured
Obligations may, in its own name, or in the name of a designee or nominee, buy
the Pledged Collateral at any public sale and, if permitted by applicable law,
buy the Pledged Collateral at any private sale.  The Pledgor will pay to the
Agent all reasonable expenses (including, without limitation, court costs and
reasonable attorneys' and


<PAGE>   8
paralegals' fees and expenses) of, or incidental to, the enforcement of any of
the provisions hereof.  The Agent agrees to distribute any proceeds of the sale
of the Pledged Collateral in accordance with the Credit Agreement and the
Pledgor shall remain liable for any deficiency following the sale of the
Pledged Collateral.

          (b)  Unless any of the Pledged Collateral threatens to decline
speedily in value or is or becomes of a type sold on a recognized market, the
Agent will give the Pledgor reasonable notice of the time and place of any
public sale thereof, or of the time after which any private sale or other
intended disposition is to be made.  Any sale of the Pledged Collateral
conducted in conformity with reasonable commercial practices of banks,
commercial finance companies, insurance companies or other financial
institutions disposing of property similar to the Pledged Collateral shall be
deemed to be commercially reasonable.  Notwithstanding any provision to the
contrary contained herein, the Pledgor agrees that any requirements of
reasonable notice shall be met if such notice is received by the Pledgor as
provided in Section 25 below at least ten (10) Business Days before the time of
the sale or disposition; provided, however, that Agent may give any shorter
notice that is commercially reasonable under the circumstances.  Any other
requirement of notice, demand or advertisement for sale is waived, to the extent
permitted by law.

          (c)  In view of the fact that federal and state securities laws may
impose certain restrictions on the method by which a sale of the Pledged
Collateral may be effected after a Default, the Pledgor agrees that after the
occurrence of an Event of Default, the Agent may, from time to time, attempt to
sell all or any part of the Pledged Collateral by means of a private placement
restricting the bidders and prospective purchasers to those who are qualified
and will represent and agree that they are purchasing for investment only and
not for distribution.  In so doing, the Agent may solicit offers to buy the
Pledged Collateral, or any part of it, from a limited number of investors deemed
by the Agent, in its reasonable judgment, to be financially responsible parties
who might be interested in purchasing the Pledged Collateral.  If the Agent
solicits such offers from not less than four (4) such investors, then the
acceptance by the Agent of the highest offer obtained therefrom shall be deemed
to be a commercially reasonable method of disposing of such Pledged Collateral;
provided, however, that this Section does not impose a requirement that the
Agent solicit offers from four or more investors in order for the sale to be
commercially reasonable.

          10.  Security Interest Absolute.  All rights of the Agent and security
interests hereunder, and all obligations of the Pledgor hereunder, shall be
absolute and unconditional irrespective of:

          (i)  Any lack of validity or enforceability of the Credit Agreement or
     any other agreement or instrument relating thereto;

          (ii)  Any change in the time, manner or place of payment of, or in any
     other term of, all or any part of the Liabilities, or any other amendment
     or waiver of or any consent to any departure from the Credit Agreement;

<PAGE>   9


          (iii)  Any exchange, release or non-perfection of any other
     collateral, or any release or amendment or waiver of or consent to
     departure from any guaranty, for all or any part of the Liabilities; or

          (iv)  any other circumstance which might otherwise constitute a
     defense available to, or a discharge of, the Pledgor in respect of the
     Liabilities or of this Agreement.

          11.  Agent Appointed Attorney-in-Fact.  The Pledgor hereby appoints
the Agent its attorney-in-fact, with full authority, in the name of the Pledgor
or otherwise, after the occurrence and during the continuation of an Event of
Default, from time to time in the Agent's sole discretion, to take any action
and to execute any instrument which the Agent may deem necessary or advisable to
accomplish the purposes of this Agreement, including, without limitation, to
receive, endorse and collect all instruments made payable to the Pledgor
representing any cash distribution, interest payment or other distribution in
respect of the Pledged Collateral or any part thereof and to give full discharge
for the same, to exercise all rights of a member and manager (upon the election
of the Agent) such as all voting, consent, managerial and other member rights,
and to arrange for the transfer of all or any part of the Pledged Collateral on
the books of GRCL and of GOCL to the name of the Agent or the Agent's nominee.

          12.  Waivers; Marshalling.  (a)  The Pledgor waives presentment and
demand for payment of any of the Liabilities, protest and notice of dishonor or
default with respect to any of the Liabilities and all other notices to which
the Pledgor might otherwise be entitled except as otherwise expressly provided
herein or in the Credit Agreement.

     (b)  Neither the Agent nor any Holder of Secured Obligations shall be
required to marshall any present or future collateral security for (including
but not limited to this Agreement and the Pledged Collateral), or other
assurances of payment of, the Obligations or any of them, or to resort to such
collateral security or other assurances of payment in any particular order. All
of the Agent's rights hereunder and of the Holders of Secured Obligations and
the Agent in respect of such collateral security and other assurances of payment
shall be cumulative and in addition to all other rights, however existing or
arising.  To the extent that it lawfully may, the Pledgor hereby agrees that it
will not invoke any law relating to the marshalling of collateral that might
cause delay in or impede the enforcement of the Agent's rights under this
Agreement or under any other instrument evidencing any of the Obligations or
under which any of the Obligations is outstanding or by which any of the
Obligations is secured or payment thereof is otherwise assured, and to the
extent that it lawfully may, the Pledgor hereby irrevocably waives the benefits
of all such laws.

          13.  Term.  This Agreement shall remain in full force and effect until
the Liabilities (other than continuing indemnity obligations) have been fully
and indefeasibly paid in cash and the Credit Agreement has terminated pursuant
to its terms.  Upon the termination of this Agreement as provided above (other
than as a result of the sale of the Pledged Collateral), the Agent will release
the security interest created hereunder and, if it then has possession of the
Pledged Membership Interest or other Pledged 

<PAGE>   10

Collateral, will deliver the Pledged Membership Interest and the Powers or such
other Pledged Collateral to the Pledgor.

          14.  Definitions.  The singular shall include the plural and vice
versa and any gender shall include any other gender as the context may require.

          15.  Successors and Assigns.  This Agreement shall be binding upon and
inure to the benefit of the Pledgor, the Agent, for the benefit of itself and
the Holders of Secured Obligations, and their respective successors and assigns.
The Pledgor's successors and assigns shall include, without limitation, a
receiver, trustee or debtor-in-possession of or for the Pledgor.

          16.  GOVERNING LAW.  THE AGENT HEREBY ACCEPTS THIS AGREEMENT, ON
BEHALF OF ITSELF AND THE HOLDERS OF SECURED OBLIGATIONS, AT NEW YORK, NEW YORK
BY ACKNOWLEDGING AND AGREEING TO IT THERE.  ANY DISPUTE BETWEEN THE AGENT OR ANY
HOLDER OF SECURED OBLIGATIONS AND THE PLEDGOR ARISING OUT OF OR RELATED TO THE
RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT, AND
WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE RESOLVED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

          17.  Consent to Jurisdiction; Counterclaims; Forum Non Conveniens.
(a) Exclusive Jurisdiction.  Except as provided in subsection (b) of this
Section 17, the Agent, on behalf of itself and the Holders of Secured
Obligations, and the Pledgor agree that all disputes between them arising out of
or related to the relationship established between them in connection with this
Agreement, whether arising in contract, tort, equity, or otherwise, shall be
resolved only by state or federal courts located in New York, New York, but the
parties acknowledge that any appeals from those courts may have to be heard by a
court located outside of New York, New York.

          (b)  Other Jurisdictions.  The Agent shall have the right to proceed
against the Pledgor or its real or personal property in a court in any location
to enable the Agent to obtain personal jurisdiction over the Pledgor, to realize
on the Pledged Collateral or any other security for the Liabilities or to
enforce a judgment or other court order entered in favor of the Agent. The
Pledgor shall not assert any permissive counterclaims in any proceeding brought
by the Agent arising out of or relating to this Agreement.

          (c)  Venue; Forum Non Conveniens.  Each of the Pledgor and the Agent
waives any objection that it may have (including, without limitation, any
objection to the laying of venue or based on forum non conveniens) to the
location of the court in which any proceeding is commenced in accordance with
this Section 17.

          18.  Service of Process.  The Pledgor waives personal service of any
process upon it and, as security for the Liabilities, irrevocably appoints The
Prentice Hall Corporation System, Inc., 1013 Centre Road, Wilmington, Delaware
19805, as its registered agent for the purpose of accepting service of process
issued by any court.

          19.  WAIVER OF JURY TRIAL.  EACH OF THE PLEDGOR AND THE AGENT WAIVES
ANY RIGHT TO TRIAL BY JURY IN ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT,
OR 

<PAGE>   11

OTHERWISE, BETWEEN THE AGENT AND THE PLEDGOR ARISING OUT OF OR RELATED
TO THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY OTHER INSTRUMENT,
DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH.  EITHER THE
PLEDGOR OR THE AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS
AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES
HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

          20.  Waiver of Bond.  The Pledgor waives the posting of any bond
otherwise required of the Agent in connection with any judicial process or
proceeding to realize on the Pledged Collateral or any other security for the
Liabilities, to enforce any judgment or other court order entered in favor of
the Agent, or to enforce by specific performance, temporary restraining order,
or preliminary or permanent injunction, this Agreement or any other agreement or
document between the Agent and the Pledgor.

          21.  Advice of Counsel.  The Pledgor represents and warrants to the
Agent and the Holders of Secured Obligations that it has consulted with its
legal counsel regarding all waivers under this Agreement, including without
limitation those under Section 12 and Sections 16 through 20 hereof, that it
believes that it fully understands all rights that it is waiving and the effect
of such waivers, that it assumes the risk of any misunderstanding that it may
have regarding any of the foregoing, and that it intends that such waivers shall
be a material inducement to the Agent and the Holders of Secured Obligations to
extend the indebtedness secured hereby.

          22.  Severability.  Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but, if any provision of this Agreement shall be held to be
prohibited or invalid under applicable law, such provision shall be ineffective
only to the extent of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this Agreement.

          23.  Further Assurances.  The Pledgor agrees that it will cooperate
with the Agent and will execute and deliver, or cause to be executed and
delivered, all such other stock powers, proxies, instruments and documents, and
will take all such other actions, including, without limitation, the execution
and filing of financing statements, as the Agent may reasonably request from
time to time in order to carry out the provisions and purposes of this
Agreement.

          24.  The Agent's Duty of Care.  The Agent shall not be liable for any
acts, omissions, errors of judgment or mistakes of fact or law, including,
without limitation, acts, omissions, errors or mistakes with respect to the
Pledged Collateral, except for those arising out of or in connection with the
Agent's (i) gross negligence or willful misconduct, or (ii) failure to use
reasonable care with respect to the safe custody of the Pledged Collateral in
the Agent's possession.  Without limiting the generality of the foregoing, the
Agent shall be under no obligation to take any steps necessary to preserve
rights in the Pledged Collateral against any other parties but may do so at its
option.  All expenses incurred in connection therewith shall be for the sole
account of the Pledgor, and shall constitute part of the Liabilities secured
hereby.

<PAGE>   12


          25.  Notices.  The Pledgor appoints Borrower as its agent to receive
notices and other communications under this Agreement.  Any such notice or
communication received by Borrower under this Agreement shall be deemed to have
been received by the Pledgor.  All such notices to Borrower shall be given in
the manner and to the addresses set forth in the Credit Agreement.

acknowledges that the Agent may, in its discretion, appoint one or more
financial institutions to act as the Agent's agent in holding in custodial
account instruments or other financial assets in which the Agent on behalf of
the Lenders and the Agent is granted a security interest hereunder, including,
without limitation, certificates of deposit and other instruments evidencing
short-term obligations.
        
          (c)  Notwithstanding the foregoing provisions of this Section 2, such
grant of security interest shall not extend to, and the term "Collateral" shall
not include, any chattel paper and general intangibles which are now or
hereafter held by the Company as licensee, lessee or otherwise, to the extent
that (i) such chattel paper and general intangibles are not assignable or
capable of being encumbered as a matter of law or under the terms of the
license, lease or other agreement applications thereto (but solely to the extent
that any such restriction shall be enforceable under applicable law), without
the consent of the licensor or lessor thereof or other applicable party thereto
and (ii) such consent has not been obtained; provided, however, that the
foregoing grant of security interest shall extend to, and the term "Collateral"
shall include, (A) any and all proceeds of such chattel paper and general
intangibles to the extent that the assignment or encumbering of such proceeds is
not so restricted and (B) upon any such licensor, lessor or other applicable
party consent with respect to any otherwise excluded chattel paper or general
intangibles being obtained, thereafter such chattel paper or general intangibles
as well as any and all proceeds thereof that might have theretofore have been
excluded from such grant of a security interest and the term "Collateral".

          Section 3.  Title to Collateral, etc.  The Company is the owner of the
Collateral free from any adverse lien, security interest or other encumbrance,
except for the security interest created by this Agreement and other liens
permitted by the Credit Agreement.  None of the Collateral constitutes, or is
the proceeds of, "farm products" as defined in Section 9-109(3) of the Uniform
Commercial Code of the State of Louisiana.  None of the account debtors in
respect of any accounts, chattel paper or general intangibles and none of the
obligors in respect of any instruments included in the Collateral is a
Governmental Authority subject to the Federal Assignment of Claims Act.

          Section 4.  Continuous Perfection.  The Company's place of business
or, if more than one, chief executive office is indicated on the Perfection
Certificate delivered to the Agent herewith (the "Perfection Certificate").  The
Company will not change the same, or the name, identity or corporate structure
of the Company in any manner, without providing at least 30 days' prior written
notice to the Agent.  The Collateral other than the Delta Queen and the
Mississippi Queen and any Collateral located thereon, to the extent not
delivered to the Agent pursuant to Section 2(b), will be kept at those locations
listed on the Perfection Certificate and the Company will not remove the
Collateral from such locations, except with respect to inventory as required in
the ordinary course of business, without providing at least 30 days' prior
written notice to the Agent.

          Section 5.  No Liens.  Except for the security interest herein granted
and liens permitted by the Credit Agreement, the Company shall be the owner of
the Collateral free from any lien, security interest or other encumbrance, and
the Company shall 



                                      -3-
<PAGE>   4

defend the same against all claims and demands of all Persons at any time
claiming the same or any interests therein adverse to the Agent or any of the
Lenders. The Company shall not pledge, mortgage or create, or suffer to exist a
security interest in the Collateral in favor of any Person other than Agent, for
the benefit of the Lenders and the Agent, except for liens permitted by the
Credit Agreement.

          Section 6.  No Transfers.  Subject to the provisions of the Credit
Agreement, the Company will not sell or offer to sell or otherwise transfer the
Collateral or any interest therein except for sales or other dispositions of
obsolescent items of equipment in the ordinary course of business consistent
with past practices.

          Section 7.  Insurance.

          (a)  Subject to the provisions of the Credit Agreement, the Company
will maintain with financially sound and reputable insurers insurance with
respect to its properties and business against such casualties and contingencies
as shall be in accordance with general practices of businesses engaged in
similar activities in similar geographic areas.  Such insurance shall be in such
amounts that the Company will not be deemed a co-insurer under applicable
insurance laws, regulations and policies and otherwise shall be in such amounts,
contain such terms, be in such forms and be for such periods as may be
reasonably satisfactory to the Agent.  In addition, all such insurance shall be
payable to the Agent as loss payee under a "standard mortgage" loss payee clause
for the benefit of the Lenders and the Agent.  Without limiting the foregoing,
the Company will (i) maintain all such worker's compensation or similar
insurance as may be required by law and (ii) maintain, in amounts and with
deductibles equal to those generally maintained by businesses engaged in similar
activities in similar geographic areas, general public liability insurance
against claims of bodily injury, death or property damage occurring, on, in or
about the properties of the Company and business interruption insurance.

          (b)  Subject to the provisions of the Credit Agreement, the proceeds
of any casualty insurance in respect of the casualty loss of any of the
Collateral shall, subject to the rights, if any, of other parties with a prior
interest in the property covered thereby, (i) so long as no Event of Default has
occurred and is continuing and to the extent that the amount of such proceeds is
less than $1,000,000, be disbursed to the Company for direct application by the
Company solely to the repair or replacement of the Company's property so damaged
or destroyed and (ii) in all other circumstances, be held by the Agent as cash
collateral for the Guaranteed Obligations.  The Agent may, at its sole option,
disburse from time to time all or any part of such proceeds so held as cash
collateral, upon such terms and conditions as the Agent may reasonably
prescribe, for direct application by the Company solely to the repair or
replacement of the Company's property so damaged or destroyed, or the Agent may
apply all or any part of such proceeds to the Guaranteed Obligations.

          (c)  All policies of insurance shall provide for at least thirty days'
prior written cancellation notice to the Agent.  In the event of failure by the
Company to provide and maintain insurance as herein provided, the Agent may, at
its option, provide such insurance and charge the amount thereof to the Company
plus interest at the Default Rate as set forth in the Credit Agreement.  The
Company shall furnish the Agent 


                                      -4-
<PAGE>   5

with certificates of insurance and policies evidencing compliance with the
foregoing insurance provision.

          Section 8.  Maintenance of Collateral; Compliance with Law. The
Company will keep the Collateral in good order and repair and will not use the
same in violation of law or any policy of insurance thereon.  The Agent, or its
designee, may inspect the Collateral at any reasonable time, wherever located.

          Section 9.  Collateral Protection Expenses; Preservation of
Collateral.

          (a)  In its discretion, the Agent may, upon ten (10) days' prior
written notice to the Company so long as no Event of Default has occurred and is
continuing (and otherwise without prior notice), discharge taxes and other
encumbrances at any time levied or placed on any of the Collateral, make repairs
thereto and pay any necessary filing fees.  The Company agrees to reimburse the
Agent on demand for any and all expenditures so made.  The Agent shall have no
obligation to the Company to make any such expenditures, nor shall the making
thereof relieve the Company of any default.

          (b)  Anything herein to the contrary notwithstanding, the Company
shall remain liable under each contract or agreement comprised in the Collateral
to be observed or performed by the Company thereunder.  Neither the Agent nor
any Lender shall have any obligation or liability under any such contract or
agreement by reason of or arising out of this Agreement or the receipt by the
Agent or any Lender of any payment relating to any of the Collateral, nor shall
the Agent or any Lender be obligated in any manner to perform any of the
obligations of the Company under or pursuant to any such contract or agreement,
to make inquiry as to the nature or sufficiency of any payment received by the
Agent or any Lender in respect of the Collateral or as to the sufficiency of any
performance by any party under any such contract or agreement, to present or
file any claim, to take any action to enforce any performance or to collect the
payment of any amounts which may have been assigned to the Agent or to which the
Agent or any Lender may be entitled at any time or times.  The Agent's sole duty
with respect to the custody, safe keeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the Uniform Commercial Code
or otherwise, shall be to deal with such Collateral in the same manner as the
Agent deals with similar property for its own account.


          Section 10.  Securities and Deposits.  If an Event of Default shall
have occurred and be continuing, (i) the Agent may at any time, at its option,
transfer to itself or any nominee any securities constituting Collateral,
receive any income thereon and hold such income as additional Collateral or
apply it to the Guaranteed Obligations, and (ii) whether or not any Guaranteed
Obligations are due, the Agent may demand, sue for, collect, or make any
settlement or compromise which it deems desirable with respect to the
Collateral.  Regardless of the adequacy of Collateral or any other security for
the Guaranteed Obligations, any deposits or other sums at any time credited by
or due from the Agent or any Lender to the Company may at any time be applied to
or set off against any of the Guaranteed Obligations.

          Section 11.  Notification to Account Debtors and Other Obligors.  If
an Event of Default shall have occurred and be continuing, the Company shall, at
the request of the 


                                      -5-
<PAGE>   6

Agent, notify account debtors on accounts, chattel paper and general intangibles
of the Company and obligors on instruments for which the Company is an obligee
of the security interest of the Agent in any account, chattel paper, general
intangible or instrument and that payment thereof is to be made directly to the
Agent or to any financial institution designated by the Agent as the Agent's
agent therefor, and the Agent may itself, if an Event of Default shall have
occurred and be continuing, without notice to or demand upon the Company, so
notify account debtors and obligors.  After the making of such a request or the
giving of any such notification, the Company shall hold any proceeds of
collection of accounts, chattel paper, general intangibles and instruments
received by the Company as trustee for the Agent, for the benefit of the Lenders
and the Agent, without commingling the same with other funds of the Company and
shall turn the same over to the Agent in the identical form received, together
with any necessary endorsements or assignments.  The Agent shall apply the
proceeds of collection of accounts, chattel paper, general intangibles and
instruments received by the Agent to the Guaranteed Obligations, such proceeds
to be immediately entered after final payment in cash or solvent credits of the
items giving rise to them.

          Section 12.  Further Assurances.  The Company, at its own expense,
shall do, make, execute and deliver all such additional and further acts,
things, deeds assurances and instruments as the Agent may require more
completely to vest in and assure to the Agent and the Lenders their respective
rights hereunder or in any of the Collateral, including, without limitation, (a)
executing, delivering and, where appropriate, filing financing statements and
continuation statements under the Uniform Commercial Code, (b) obtaining
governmental and other third party consents and approvals, including without
limitation any consent of any licensor, lessor or other applicable party
referred to in Section 2(c), (c) obtaining waivers from mortgagees and landlords
and (d) taking all actions required by Sections 8-313 and 8-321 of the Uniform
Commercial Code, as applicable in each relevant jurisdiction, with respect to
certificated and uncertificated securities.

          Section 13.  Power of Attorney.

          (a)  The Company hereby irrevocably constitutes and appoints the Agent
and any officer or agent thereof, with full power of substitution, as its true
and lawful attorneys-in-fact with full irrevocable power and authority in the
place and stead of the Company or in the Agent's own name, for the purpose of
carrying out the terms of this Agreement, to take any and all appropriate action
and to execute any and all documents and instruments that may be necessary or
desirable to accomplish the purposes of this Agreement and, without limiting the
generality of the foregoing, hereby gives said attorneys the power and right, on
behalf of the Company, without notice to or assent by the Company, to do the
following:

          (i)  upon the occurrence and during the continuance of an Event of
     Default, generally to sell, transfer, pledge, make any agreement with
     respect to or otherwise deal with any of the Collateral in such manner as
     is consistent with the Uniform Commercial Code and as fully and completely
     as though the Agent were the absolute owner thereof for all purposes, and
     to do at the Company's expense, at any time, or from time to time, all acts
     and things which the Agent deems necessary to protect, preserve or realize
     upon the Collateral and the Agent's security interest 


                                      -6-
<PAGE>   7

     therein, in order to effect the intent of this Agreement, all as fully and
     effectively as the Company might do, including, without limitation, (A) the
     filing and prosecuting of registration and transfer applications with the
     appropriate federal or local agencies or authorities with respect to
     trademarks, copyrights and patentable inventions and processes, (B) upon
     written notice to the Company, the exercise of voting rights with respect
     to voting securities, which rights may be exercised, if the Agent so
     elects, with a view to causing the liquidation in a commercially reasonable
     manner of assets of the issuer of any such securities and (C) the
     execution, delivery and recording, in connection with any sale or other
     disposition of any Collateral, of the endorsements, assignments or other
     instruments of conveyance or transfer with respect to such Collateral; and

          (ii)  to file such financing statements with respect hereto, with or
     without the Company's signature, or a photocopy or carbon copy of this
     Agreement or of a signed financing statement in substitution for a
     financing statement, as the Agent may deem appropriate and to execute in
     the Company's name such financing statements and continuation statements
     which may require the Company's signature.

          (b)  To the extent permitted by law, the Company hereby ratifies all
that said attorneys shall lawfully do or cause to be done by virtue hereof.
This power of attorney is a power coupled with an interest and shall be
irrevocable.

          (c)  The powers conferred on the Agent hereunder are solely to protect
the interests of the Agent and the Lenders in the Collateral and shall not
impose any duty upon the Agent to exercise any such powers.  The Agent shall be
accountable only for the amounts that it actually receives as a result of the
exercise of such powers and neither it nor any of its officers, directors,
employees or agents shall be responsible to the Company for any act or failure
to act, except for the Agent's own gross negligence or willful misconduct.


          Section 14.  Remedies.  If an Event of Default shall have occurred and
be continuing, the Agent may, without notice to or demand upon the Company,
declare this Agreement to be in default, and the Agent shall thereafter have in
any jurisdiction in which enforcement hereof is sought, in addition to all other
rights and remedies, the rights and remedies of a secured party under the
Uniform Commercial Code, including, without limitation, the right to take
possession of the Collateral, and for that purpose the Agent may, so far as the
Company can give authority therefor, enter upon any premises on which the
Collateral may be situated and remove the same therefrom.  The Agent may require
the Company to assemble all or any part of the Collateral at such location or
locations within the state(s) of the Company's principal office(s) or at such
other locations as the Agent may designate.  Unless the Collateral is perishable
or threatens to decline speedily in value or is of a type customarily sold on a
recognized market, the Agent shall give to the Company at least ten (10)
Business Days' prior written notice of the time and place of any public sale of
Collateral or of the time after which any private sale or any other intended
disposition is to be made.  The Company hereby acknowledges that ten (10)
Business Days' prior written notice of such sale or sales shall be reasonable
notice.  In addition, the Company waives any and all rights that it may have to
a judicial hearing in advance of the enforcement of any of the Agent's rights 



                                      -7-
<PAGE>   8

hereunder, including, without limitation, its right following an Event of
Default to take immediate possession of the Collateral and to exercise its
rights with respect thereto.  To the extent that any of the Guaranteed
Obligations are to be paid or performed by a Person other than the Company, the
Company waives and agrees not to assert any rights or privileges which it may
have under Section 9-112 of the Uniform Commercial Code.

          Section 15.    Special Louisiana Provisions.  The Company hereby 
agrees as follows:

          (a)  For purposes of Louisiana executory process, the Company
acknowledges the Guaranteed Obligations secured hereby, whether now existing or
to arise hereafter, and confesses judgment thereon.  Upon the occurrence of an
Event of Default and at any time thereafter so long as the same shall be
continuing, and in addition to all other rights and remedies granted the Agent
hereunder, it shall be lawful for and the Company hereby authorizes the Agent
without making a demand or putting the Company in default, a putting in default
being expressly waived, to cause all and singular the Collateral to be seized
and sold after due process of law, the Company waiving the benefit of any and
all laws or parts of laws relative to the appraisement of property seized and
sold under executory process or other legal process, and consenting that the
Collateral be sold without appraisement, either in its entirety or in lots or
parcels, as the Agent may determine, to the highest bidder for cash or on such
other terms as the plaintiff in such proceedings may direct.  In addition, the
Agent shall have all of the rights and remedies available to it under this
Agreement or under the Louisiana Commercial Laws (Louisiana Revised Statutes,
Title 10), then in effect, and under Chapter 9 of the Louisiana Commercial Laws,
then in effect (La. R.S. 10:9-101 et seq.).

          (b)  the Company hereby waives:

            (i)  the benefit of appraisement provided for in Articles 2332,
          2336, 2723 and 2724 of the Louisiana Code of Civil Procedure and all
          other laws conferring the same;

            (ii)  the demand and three (3) days' notice of demand as provided in
          Articles 2639 and 2721 of the Louisiana Code of Civil Procedure;

            (iii)  the notice of seizure provided by Articles 2293 and 2721 of
          the Louisiana Code of Civil Procedure; and

            (iv)  the three (3) days' delay provided for in Articles 2331 and
          2722 of the Louisiana Code of Civil Procedure.

          (c)      the Company expressly authorizes and agrees that the Agent
shall have the right to appoint a keeper of the Collateral, or any part thereof,
pursuant to the terms and provisions of La. R.S. 9:5136.

          Section 16.    No Waiver, etc.  The Company waives demand, notice,
protest, notice of acceptance of this Agreement, notice of loans made, credit
extended, Collateral received or delivered or other action taken in reliance
hereon and all other 


                                      -8-
<PAGE>   9

demands and notices of any description.  With respect to both the Guaranteed
Obligations and the Collateral, the Company assents to any extension or
postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of Collateral, to the addition or release of
any party or Person primarily or secondarily liable, to the acceptance of
partial payment thereon and the settlement, compromising or adjusting of any
thereof, all in such manner and at such time or times as the Agent may deem
advisable.  The Agent shall have no duty as to the collection or protection of
the Collateral or any income thereon, nor as to the preservation of rights
against prior parties, nor as to the preservation of any rights pertaining
thereto beyond the safe custody thereof as set forth in Section 9(b).  The Agent
shall not be deemed to have waived any of its rights upon or under the
Guaranteed Obligations or the Collateral unless such waiver shall be in writing
and signed by the Agent with the consent of the Required Lenders. No delay or
omission on the part of the Agent in exercising any right shall operate as a
waiver of such right or any other right.  A waiver on any one occasion shall not
be construed as a bar to or waiver of any right on any future occasion.  All
rights and remedies of the Agent with respect to the Guaranteed Obligations or
the Collateral, whether evidenced hereby or by any other instrument or papers,
shall be cumulative and may be exercised singularly, alternatively, successively
or concurrently at such time or at such times as the Agent deems expedient.

          Section 17.   Marshalling.  Neither the Agent nor any Lender
shall be required to marshal any present or future collateral security
(including but not limited to this Agreement and the Collateral) for, or other
assurances of payment of, the Guaranteed Obligations or any of them or to resort
to such collateral security or other assurances of payment in any particular
order, and all of the rights of the Agent hereunder and of the Agent or any
Lender in respect of such collateral security and other assurances of payment
shall be cumulative and in addition to all other rights, however existing or
arising.  To the extent that it lawfully may, the Company hereby agrees that it
will not invoke any law relating to the marshalling of collateral which might
cause delay in or impede the enforcement of the Agent's rights under this
Agreement or under any other instrument creating or evidencing any of the
Guaranteed Obligations or under which any of the Guaranteed Obligations is
outstanding or by which any of the Guaranteed Obligations is secured or payment
thereof is otherwise assured, and, to the extent that it lawfully may, the
Company hereby irrevocably waives the benefits of all such laws.

          Section 18.   Proceeds of Dispositions; Expenses.   The Company shall
pay to the Agent on demand any and all expenses, including reasonable attorneys'
fees and disbursements, incurred or paid by the Agent in protecting, preserving
or enforcing the Agent's rights under or in respect of any of the Guaranteed
Obligations or any of the Collateral.  After deducting all of said expenses, the
residue of any proceeds of collection or sale of the Guaranteed Obligations or
Collateral shall, to the extent actually received in cash, be applied to the
payment of the Guaranteed Obligations in such order or preference as the Agent
may determine in its sole discretion proper allowance being made for any
Guaranteed Obligations not then due.  Upon the indefeasible payment and
satisfaction in full of all of the Guaranteed Obligations and the termination of
all financial arrangement among the Borrower and the Lenders, and after making
any payments required by Section 9-504(1)(c) of the Uniform Commercial Code, any
excess shall be returned to the Company, and the Company shall remain liable for
any deficiency in the payment of the Guaranteed Obligations.

          Section 19.       Agent.  The Agent shall exercise its rights and
remedies hereunder in accordance with the provisions of the Credit Agreement,
including without limitation the provisions for acting upon the request or at
the direction of one or more of the Lenders.

          Section 20.       Overdue Amounts.  Until paid, all amounts due and

shall bear, whether before or after judgment, interest at the Default Rate as
set forth in the Credit Agreement.

This Confirmation of Guaranty Agreement, effective as of December 31, 1996, is
made by The Delta Queen Steamboat Co., a corporation organized and existing
under the laws of the State of Delaware (the "Guarantor"), in favor of the
United States of America, represented by the Secretary of Transportation,
acting by and through the Maritime Administration (the "Secretary").  

     WHEREAS, on August 24, 1995, the Guarantor executed a Guaranty Agreement
     (the "Guaranty Agreement") in favor of the Secretary, relating to the
     guarantee of the due and punctual payment of United States Government
     Guaranteed Ship Financing Obligations, American Queen Series, made up of
     the 2005 Notes and the 2020 Bonds (the "Obligations") in the amount of
     $60,589,000.00, of which $58,165,000.00 are Outstanding on the date hereof,
     issued by Great AQ Steamboat Co., a Delaware corporation (the "Original
     Shipowner"), pursuant to the Secretary's Note.  

     WHEREAS, effective as of December 31, 1996, the Original Shipowner merged
     (the "Merger") into Great AQ Steamboat, L.L.C., a Delaware limited
     liability company (the "LLC") with the LLC being the successor entity,
     assuming all of the rights, duties and obligations of the Original
     Shipowner, including the Obligations and the Secretary's Note.  

     WHEREAS, effective December 31, 1996, the LLC has endorsed the Secretary's

     and valuable consideration, the receipt and adequacy of which are hereby
     acknowledged, Guarantor hereby acknowledges that the LLC has endorsed the

     of interest on the 2005 Notes and of assuming payment of the Obligations,
     and the Guarantor consents to such endorsement and confirms each and every
     term and obligation of the Guaranty Agreement and further confirms that it
     is absolutely, irrevocably and unconditionally bound by the Guaranty
     Agreement subsequent to the Merger as if the LLC had been an original party
     to the Secretary's Note, and as if the interest calculation applicable to

                        ADDENDUM TO THE SECRETARY'S NOTE

          Interest on this Secretary's Note shall be payable from August 24,
1995, semi-annually on February 24 and August 24 of each year, commencing
February 24, 1996, until the principal sum has been paid at the following rates:

          1. With respect to principal relating to the 2005 Notes, said amounts
shall bear interest at a floating rate equal to 0.25% plus the six (6) month
London Interbank Borrowing Rate ("LIBOR"), calculated on the basis of the actual
number of days for which interest is payable divided by 360 from the interest
payment date referred to above next preceding the date of this Secretary's Note
to which interest on the 2005 Notes has been paid (unless the date hereof is the
date to which interest on the 2005 Notes has been paid, in which case from the
date of this Secretary's Note), or if no interest has been paid on the 2005
Notes since the date of the Secretary's Note, from such date, until payment of
said principal sum has been made or duly provided for, and at the same rate per
annum on any overdue principal; if all or a portion of any principal or interest
due on this Secretary's Note is not paid by the Shipowner when due, such overdue
amount shall bear interest at the rate per annum that otherwise would be
applicable pursuant to the following paragraph (for Reset Periods, as
hereinafter defined, of six (6) months), notwithstanding any other provision of
this Secretary's Note, in no event shall the interest rate of this Secretary's
Note, with respect to amounts Outstanding relating to the 2005 Notes, whether
pre-default or post-default, exceed 12.55% per annum.

          The floating interest rate is calculated as follows:  Two Business
Days prior to the commencement of each Reset Period, as such term is defined
below ("Interest Reset Date"), the Indenture Trustee will determine LIBOR for
such Reset Period on the basis of the offered rates for deposits in United
States dollars having a maturity of six (6) months (and, if so categorized, in a
principal amount comparable to the amount scheduled to be Outstanding under the
2005 Notes [having the same Reset Period] during such Reset Period) which appear
on the Reuters Screen LIBO page as of 11:00 a.m., London time.  If at least two
such offered rates appear on the Reuters Screen LIBO page, LIBOR for such Reset
Period shall be the arithmetic average (rounded upwards, if necessary to the
nearest 1/100 of 1%) of such offered rates on the applicable Interest Reset
Date, as determined by the Indentured Trustee.  If fewer than two offered rates
appear, LIBOR for such Reset Period shall be the arithmetic average (rounded
upwards if necessary, to the nearest 1/100 of 1%) of the rates quoted at
approximately 11:00 a.m., New York time, on such Interest Reset Date by three
major banks in New York City selected by the Indenture Trustee as the rates at
which such banks offer deposits in United States dollars to leading banks in the
interbank eurodollar market for delivery on the first day of such Reset Period,
having a maturity of six (6) months and in a principal amount comparable to the
amount scheduled to be Outstanding under the 2005 Notes (having the same Reset
Period) during such Reset Period; provided, however, that if the banks in New
York City selected by the Indenture Trustee are not quoting rates as mentioned
herein, LIBOR for such Reset Period shall be the single rate appearing on the
Reuters Screen LIBO Page in effect on such Interest Reset Date, or, if no such
rate appears, LIBOR for such Reset Period shall be as determined on the previous
Interest Reset Date.  For the purpose of calculation of the 

<PAGE>   4

LIBOR rate, the term "Reset Period" will mean (i) initially, the period from and
including the date of this Secretary's Note and ending on but excluding the
twenty-fourth (24th) day of February, 1996 and (ii) thereafter, each successive
period beginning on the last day of the next preceding Reset Period and ending
on but excluding the twenty-fourth (24th) day of the next succeeding sixth
calendar month, provided, however, if any Reset Period would otherwise end on a
day which is not a Business Day, such Reset Period will be extended to the next
succeeding Business Day; and provided, further, with respect to overdue amounts
of principal and interest on the 2005 Notes, the Reset Period will also be
provided herein.

          2.  With respect to principal relating to the 2020 Bonds, this
Secretary's Note shall bear interest at the rate of 7.68%.

Subordinated Debt, the Debtor shall not repay the Subordinated Debt unless and
until the Senior Debt has been paid in full; provided, however, that in the
event of a default under the Subordinated Debt, the Subordinated Creditors may
seek recourse against the Debtor, but only with the prior written consent of
the Secretary, which shall be granted or withheld in his sole discretion.

              8.  DEFAULT AND NET WORTH OF DEBTOR.  In the event and during the
continuance of any default by the Debtor or the Subordinated Creditors in the
observance or performance of any of the provisions of this Subordination
Agreement, the Subordinated Debt shall forthwith cease to be included in New
Worth, as defined in the RFFA, without any requirement for notice, demand, or
other action by the Secretary.

              9.  DEBTOR'S REPRESENTATIONS AND WARRANTIES.  The Debtor hereby
represents and warrants to the Secretary (a) that the factual statements set
forth in the recitals herein are true and accurate; and (b) that it has made
all Senior Loan Documents available to the Subordinated Creditors.

             10. SUBORDINATED CREDITORS' REPRESENTATIONS AND WARRANTIES.  The
Subordinated Creditor each hereby represents and warrants to the Secretary (a)
that the factual statements set forth in the recitals herein are true and
accurate; and (b) that it has either reviewed all the Senior Loan Documents or
hereby waives such review.

             11. SPECIFIC PERFORMANCE.  Subordinated Creditors hereby agree
that Senior Creditor is hereby authorized to demand specific performance of
this Agreement at any time Subordinated Creditors shall have failed to comply
with any of the provisions of this Agreement applicable to it.  Subordinated
Creditors hereby irrevocably waive any defense based on the adequacy of a
remedy at law, which might be asserted as a bar to such remedy of specific
performance.

             12. ASSIGNMENTS AND OTHER INSTRUMENTS.  Subordinated Creditors
agree to execute and deliver to Senior Creditor such assignments or other
instruments as may be requested by Senior Creditor to enable it to enforce its
rights hereunder, and to collect any and all dividends or other payments or
disbursements which may be made at any time on account of all or any of the
Subordinated Debt so long as any Senior Debt remains due and unpaid.

             13. REFERENCES TO SUBORDINATION.   Upon the request of the
Secretary, Subordinated Creditors (a) shall cause the Subordinated Loan
Documents, and any amendment, renewal or extension thereof, to refer, in form
and substance satisfactory to the Secretary, to the fact that the indebtedness
evidenced by each such instrument is 

<PAGE>   5

subordinated to the Senior Debt under this Subordination Agreement; (b) shall
further mark its books of accounts in such a manner as shall be effective to
give proper notice of the effect of this Agreement; and (c) shall, at any time
and from time to time, promptly execute and deliver all additional instruments
and documents, and take all further action, as may be necessary or desirable, in
the opinion of Senior Creditor, to protect any right or interest granted or
purported to be granted by this Agreement and to enable Senior Creditor to
exercise and enforce its rights and remedies hereunder.

             14.  NO LIABILITY FOR ACTIONS BY SENIOR CREDITOR. The parties 
hereto agree that Senior Creditor shall not be liable for any action or
failure to act under or in connection with any of the documents or instruments
creating the Senior Liens or the Senior Debt, it being understood that the
decision of whether and when to act and the manner of proceeding under such
instruments and documents are within the sole discretion of Senior Creditor and
shall not be affected in any manner by the existence of the Subordinated Debt
and the Subordinated Liens.  The parties hereto further agree that such
obligations as may be imposed under the documents and instruments creating the
Senior Liens or under the Uniform Commercial Code or other applicable laws
shall run exclusively to the benefit of the Senior Creditor and may be enforced
or waived by the Senior Creditor and not by the Subordianted Creditor.

             15.  NO DUTY TO INFORM SUBORDINATED CREDITORS.  Nothing in this
Agreement shall be construed as imposing on Senior Creditor an obligation to
inform Subordinated Creditors of any defaults arising under the Senior Loan
Documents or to provide Subordinated Creditors with any financial or other
information of which Senior Creditor is or becomes aware with respect to the
Debtor.  Without limiting the generality of the foregoing, Senior Creditor
shall not be obligated to provide Subordinated Creditors with a notice that an
event of default has occurred under the Senior Loan Documents.

             16.  RIGHTS OF SUBROGATION.  Subordinated Creditors agree that no
payment or distribution to Senior Creditor pursuant to the provisions of this
Agreement shall entitle Subordinated Creditors to exercise any rights of
subrogation in respect thereof until the Senior Debt has been paid in full.

             17.  NO ASSIGNMENT OF SUBORDINATED DEBT.  Subordinated Creditors
shall not, without Senior Creditor's prior written consent, sell, assign,
pledge, encumber or otherwise dispose of any of the Subordinated Debt, and any
attempt to do so shall be null and void ab initio.

             18.  OBLIGATIONS HEREUNDER NOT AFFECTED.  All rights and interests
of Senior Creditor hereunder, and all agreements and obligations of the
Subordinated Creditors hereunder, shall remain in full force and effect
irrespective of:  (a) any lack of validity or enforceability of the Senior Loan
Documents or any other agreement or instrument relating thereto; (b) any change
in the time, manner or place of payment of, or in any other term of, all or any
of the Senior Debt, or any other amendment or waiver of or any consent to the
departure from the Senior Loan Documents; (c) any exchange, release or
nonperfection of any Senior Lien, or any release or amendment or waiver of 

<PAGE>   6

or consent to departure from any guaranty supporting all or any portion of the
Senior Debt; or (d) any other circumstances which might otherwise constitute a
defense available to, or a discharge of the Debtor in respect of the Senior Debt
or Subordinated Creditors in respect of this Agreement.  This Agreement shall
continue to be effective or be reinstated, as the case may be, if at any time
any payment of any of the Senior Debt is rescinded or must be otherwise returned
by Senior Creditor upon Debtor Insolvency, all as though such payment had not
been made.

             19.  WAIVER.  Subordinated Creditors and the Debtor hereby waive
promptness, diligence, notice of acceptance and any other notice with respect
to any of the Senior Debt and this Agreement and any requirement that Senior
Creditor protect, secure or insure any security interest or lien or property
subject thereto or exhaust any right or take any action against the Debtor or
any other person or entity or any collateral.

             20.  MISCELLANEOUS

     (a) GOVERNING LAW.  This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns, and
shall be construed and enforced in accordance with the laws of the District of
Columbia.

     (b)  SEVERABILITY.  If any of the provisions or terms of this Agreement
shall for any reason be held to be invalid or unenforceable, such invalidity or
unenforceability shall not affect any other of the terms hereof, and this
agreement shall be construed as if such unenforceable term had never been
contained herein.

     (c)  COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, each of which shall constitute an original Agreement but all of
which together shall constitute one and the same instrument.

     (d)  HEADINGS.  The descriptive headings herein are for convenience only
and shall not affect the meaning or construction of any of the provisions
hereof.

     (e)  NOTICES.   All notices and other communications provided for in
this Agreement shall be in writing or (unless otherwise specified) by telex,
telegram or facsimile transmission and shall be mailed (with first class postage
prepaid, return receipt requested) or sent or delivered to each party at the
address set forth under its name on the signature page hereof, or at such other
address as shall be designated by such party in a written notice to each other
party. Except as otherwise specified, all such notices and communications if
duly given or made shall be effective upon receipt.

     (f)  CONSENT TO JURISDICTION; WAIVER OF IMMUNITIES.  The Subordinated
Creditors hereby irrevocably submit to the jurisdiction of any federal court
sitting in the District of Columbia, in any action or proceeding brought to
enforce or otherwise arising out of or relating to this Agreement, and
irrevocably waives to the fullest extent permitted by law any objection which it
may now or hereafter have to the laying of venue in any such action or
proceeding in such forum and hereby further irrevocably waives any claim that
such forum is an inconvenient forum.  The Subordinated Creditors agree 

<PAGE>   7

that a final judgement in any such action or proceeding shall be conclusive and
may be enforced in any other jurisdiction by suit on the judgement or in any
manner provided by law.  Nothing herein shall impair the right of Senior
Creditor or the holder of the Senior Loan Documents to bring any action or
proceeding againt Subordinated Creditors or their respective properties in the
courts of any other jurisdiction, and Subordinated Creditors irrevocably submit
to the nonexclusive jurisdiction of the appropriate courts of the jurisdiction
or jurisdictions in which the Subordinated Creditors are incorporated, or
sitting in any place or places where property or an office of Subordinated
Creditors are located.

                   (g)  ENTIRE AGREEMENT; AMENDMENT.  This Agreement represents
the entire Agreement between the parties hereto and, except as expressely
provided herein, shall not be affected by reference to any other documents.
Neither this Agreement nor any provision hereof may be changed, waived,
discharged or terminated orally, but such may be accomplished only by an
instrument in writing signed by the parties hereto.

                   (h)  COSTS OF ENFORCEMENT.  Subordinated Creditors agree to
pay to Senior Creditor any and all costs and expenses, including attorney's
fees, incurred by Senior Creditor as a result of Subordinated Creditors'
default hereunder and/or in protecting and/or enforcing the rights of Senior
Creditor under this Agreement whether or not a lawsuit is commenced.
Attorneys' fees, in either case, shall include services rendered at both the
trial and appellate levels, as well as services rendered subsequent to
judgement and obtaining execution thereon.  Costs and expenses, including
attorneys' fees, shall be considered as part of the Senior Debt, as that term
is used herein.

                   (i)  CONTINUING AGREEMENT.  This Agreement is solely for
the benefit of, and shall be enforceable by the Senior Creditor, and its
successors, transferees and assigns, and no other person or persons shall have
any right, benefit, priority, or interest under, or because of the existence
of, this Agreement.  This Agreement is a continuing agreement and shall (a)
remain in full force and effect until the Senior Debt shall have been paid in
full, and (b) be binding on Subordinated Creditors, their respective successors
or assigns.  Without limiting the generality of the foregoing, Senior Creditor
may assign or otherwise transfer any other promissory note held by it
evidencing the Senior Debt to any other person or entity, and such other person
or entity shall thereupon become vested with all the rights in respect thereof
granted to Senior Creditor herein.
