                                   (UNAUDITED)


1.      FINANCIAL STATEMENTS

        The balance sheet as of June 30, 1999, the statements of operations for
        the quarters ended and the six months ended June 30, 1999 and 1998 and
        the statements of cash flows for the six months ended June 30, 1999 and
        1998 are unaudited, but in the opinion of the Company's management
        reflect all adjustments, consisting only of normal recurring
        adjustments, which are necessary to present fairly the financial
        condition and results of operations at those dates and for those
        periods. The results of operations for the interim periods are not
        necessarily indicative of results for a full year. It is suggested that
        these financial statements be read in conjunction with the audited
        financial statements and notes thereto included in the Company's Form
        10-K for the year ended December 31, 1998.


2.      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        Deferred Costs

        The Company adopted the provisions of Statement of Position 98-5
        "Reporting on the Costs of Start-up Activities" effective January 1,
        1999. The effect of adopting this statement was an additional charge of
        $1.34 million related to the write off of the unamortized balance of
        organizational costs and is included as a component of depreciation and
        amortization in the accompanying statement of operations for the six
        months ended June 30, 1999.


3.      DEBT

        NationsBank Credit Facility

        On May 16, 1997, the Company entered into a Credit Agreement (the
        "Original NationsBank Credit Agreement") with NationsBank of Texas, N.A.
        ("NationsBank"), pursuant to which NationsBank agreed to make term loans
        (the "Original NationsBank Loans") to the Company in an aggregate
        principal amount of up to $100 million. The maximum amount of the
        Original NationsBank Loans which may be outstanding at any time reduces
        quarterly commencing March 31, 1998 through the May 16, 2000 maturity
        date. Subject to the satisfaction of certain conditions precedent, the
        Company may extend the maturity date of the Original NationsBank Loans
        to December 31, 2000 and such loans will bear interest based on LIBOR
        plus 2.125%. As of December 31, 1998, the outstanding balance on the
        Original NationsBank Loans was $80 million. On March 31, 1999 and on
        June 30, 1999, the Company repaid $6.25 million bringing the outstanding
        balance of the Original NationsBank Loans down to $67.5 million.

        New NationsBank Credit Facility

        The Company entered into a second Credit Agreement (the "New NationsBank
        Credit Agreement") as of April 12, 1999, with NationsBank, pursuant to
        which NationsBank agreed to make additional term loans (the "New
        NationsBank Loans") to the Company in an aggregate principal amount of
        up to $47 million. NationsBank made the first term loan to the Company,
        under the New NationsBank Credit Agreement,

       in the principal amount of $5 million on April 28, 1999. A second term
       loan was made to the Company on June 28, 1999 in the principal amount of
       $25 million. Similar to the Original NationsBank Credit Agreement, the
       Company may elect interest periods based on one, two, three, or six month
       LIBOR. Interest accrues at LIBOR plus 2.50% and is payable at the end of
       each interest period. The maximum amount of the New NationsBank Loans
       which may be outstanding at any time reduces quarterly commencing
       December 31, 1999 through the May 16, 2000 maturity date. Subject to the
       satisfaction of certain conditions precedent, the Company may extend the
       maturity date of the New NationsBank Loans to December 31, 2000 and such
       loans will bear interest based on LIBOR plus 2.50%.

       In connection with the New NationsBank Credit Agreement, the Company
       purchased an interest rate protection agreement from Goldman Sachs
       Capital Markets L.P. capping LIBOR at 7.85%.

       As a condition to making the New NationsBank Loans, the holder of the 14%
       Debentures and the Company amended the intercreditor and subordination
       agreement, executed as part of the Original NationsBank Loans (as defined
       in the December 31, 1998 Form 10-K) to include the New NationsBank Loans
       (the Original NationsBank Loans and the New NationsBank Loans are
       hereafter referred to as the ("NationsBank Loans"). The intercreditor and
       subordination agreement provides that the holder of the 14% Debentures
       agrees (i) to subordinate payment on the 14% Debentures to the
       NationsBank Loans, (ii) that in certain circumstances interest would
       accrue but not be paid on the 14% Debentures, and (iii) that NationsBank
       may take certain actions on behalf of the holder of the 14% Debentures
       upon the occurrence of certain bankruptcy related events in respect of
       the Company.

       In addition, certain members of the Investor Group (as defined in the
       December 31, 1998 Form 10-K) and/or certain of their affiliates entered
       into a Limited Recourse Agreement dated as of April 12, 1999, in favor of
       NationsBank.


4.     RELATED PARTY TRANSACTIONS

       During 1999, the Company paid a $470,000 investment banking fee to
       Goldman, Sachs & Co., an affiliate of one member of the investor group,
       related to the closing of the New NationsBank Loans (see Note 3). This
       fee was capitalized as a component of deferred costs in the accompanying
       1999 balance sheet.

The following table shows selected lease expirations and vacancy of the Property
as of June 30, 1999. Area, as presented below and discussed above, is measured
based on standards promulgated by the New York Real Estate Board in 1987. Lease
turnover could offer an opportunity to increase the revenue of the Property or
might have a negative impact on the Property's revenue. Actual renewal and
rental income will be affected significantly by market conditions at the time
and by the terms at which the Company can then lease space.

Debt

The Zero Coupon Convertible Debentures (the "Zero Coupons") due December 31,
2000 accrete to a face value of approximately $586.2 million at an effective
annual interest rate of 12.10%. At June 30, 1999 and December 31, 1998, the
carrying value of the Zero Coupons, net of unamortized discount, was
approximately $489.3 million and $460.8 million, respectively.

The 14% Debentures have a principal balance of $75 million and mature on
December 31, 2007. At the time the Property was acquired by the Company, the
carrying value of the 14% Debentures was adjusted to reflect their estimated
fair value at that date, resulting in a premium. The effective interest rate,
which is net of the amortization of this premium, is approximately 9.03%.
Interest payments are made semi-annually on July 31

and January 31. As of June 30, 1999 and December 31, 1998, the carrying value of
the 14% Debentures was approximately $97.3 million and $98.1 million,
respectively.

As of June 30, 1999, the Original NationsBank Loans have an aggregate principal
balance of $67.5 million and mature on May 16, 2000. The Company may elect
interest periods based on one, two, three or six month LIBOR rates. Interest
accrues at LIBOR plus 1.75% and is payable monthly in arrears.

As of June 30, 1999, the New NationsBank Loans have an aggregate principal
balance of $30 million and mature on May 16, 2000. The Company may elect
interest periods based on one, two, three or six month LIBOR rates. Interest
accrues at LIBOR plus 2.50% and is payable monthly in arrears.

Cash Flow

During the six months ended June 30, 1999, the Company received cash flows of
approximately $37.0 million from operations of the Property. The Company used
part of this cash flow from operations and draws on the New NationsBank Credit
Agreement totaling $30 million to fund tenant improvements, building
improvements and other leasing costs totaling approximately $37.8 million. The
Company also made two $6.25 million amortization payments on the Original
NationsBank Loans on March 31, 1999 and on June 30, 1999 from its cash flow from
operations.

The Company believes that its current cash balance and future cash flows from
operations, together with its expected borrowings in an amount currently
believed not to exceed $17 million, will be sufficient to fund its capital and
debt service requirements for the foreseeable future.

Beginning in January 1999, the Company commenced a retail redevelopment project
which includes, among other things, the restoration of the Channel Gardens,
repaving of Rockefeller Plaza, refurbishment of the common area in the concourse
under 30 Rockefeller Plaza and the completion of numerous new retail stores.
Such work is scheduled to be finished by the end of 1999.

Inflation

Inflation and changing prices during the current period did not significantly
affect the markets in which the Company conducts its business. In view of the
moderate rate of inflation, its impact on the Company's business has not been
significant.


RESULTS OF OPERATIONS - RCPI TRUST

Base rent for the quarter and the six months ended June 30, 1999 increased
approximately $10.2 million and $18.9 million, respectively, from the quarter
and the six months ended June 30, 1998 and is due mainly to higher rental rates
on new leases, which did not exist in the prior year. Additionally, the Company
signed several new retail leases which had lease and rent commencement dates
after the first six months of 1998 and the occupancy level increased to 92.5% as
of June 30, 1999, as compared to 88.1% as of June 30, 1998.

Interest and other income decreased for the quarter and the six months ending
June 30, 1999, as compared to the quarter and the six months ending June 30,
1998, primarily due to lower interest income. The decrease in interest income
was due to a lower average cash balance during both the quarter ended March 31,
1999 and for the majority of the quarter ended June 30, 1999.

Interest expense has increased by approximately $1.4 million and $3.6 million
for the quarter and the six months ended June 30, 1999, respectively, as
compared to the quarter and the six months ended June 30, 1998, primarily due to
the increase in the outstanding debt balance. Total outstanding debt as of June
30, 1999 was approximately $684.1 million, as compared to $617.8 million as of
June 30, 1998. The increase is due primarily to accretion of the Zero Coupon
Debentures and additional draws under the NationsBank credit facilities which
have increased by $17.5 million since December 31, 1998.

The increase in depreciation and amortization expense of approximately $1.4
million and $3.8 million for the quarter and the six months ended June 30, 1999,
respectively, as compared to the quarter and the six months ended June 30, 1998,
was primarily due to additional capital projects at the Property being placed
into service since June 30, 1998 and due to additional tenant improvements and
leasing commissions expended as a result of increased leasing activity.
Additionally, the increase in amortization expense was due to the adoption of
the provisions of SOP 98-5 "Reporting on the Costs of Start-Up Activities"
effective January 1, 1999. This required the write-off of the Company's
remaining organizational costs of approximately $1.34 million.

       ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK


The Company has no material exposure to market risk sensitive instruments other
than the NationsBank Loans. The market risk associated with this floating rate
loan is minimized by an interest rate protection agreement which caps out the
floating rate on the Original NationsBank Loans at 7.69% during the first two
years of the initial term and 8.69% thereafter, including the extension period.
The New NationsBank Loans are capped at 7.85% by an interest rate protection
agreement during the entire term. The Company enters into derivative instruments
only to hedge its exposure to changes in interest rates on some of its
outstanding indebtedness, not for speculative or trading purposes, and does not
enter into leveraged derivatives. See Note 6 to the Financial Statements
included in the Company's Form 10-K for the year ended December 31, 1998 for
information about the Company's interest rate protection agreement with respect
to the Original NationsBank Loans.

                                    AMENDMENT

         AMENDMENT, dated as of April 12, 1999 (this "Amendment"), among RCPI
TRUST, a Delaware business trust (the "Borrower"), the lenders parties hereto
and NATIONSBANK, N.A., a national banking association (successor by merger to
NationsBank of Texas, N.A.), as agent (in such capacity, the "Agent") for the
Lenders, to the Existing Credit Agreement (as defined below). Capitalized terms
used but not otherwise defined herein shall have the meanings given to them in
the Existing Credit Agreement.

                                    RECITALS

         The Borrower, the lenders from time to time parties hereto (the
"Lenders") and the Agent are parties to that certain Credit Agreement, dated as
of May 16, 1997 (as previously amended and as otherwise amended, supplemented or
otherwise modified, the "Existing Credit Agreement").

         The Borrower has requested that the Lenders amend the Existing Credit
Agreement to, among other things, allow the Borrower to enter into an additional
credit agreement, dated as of the date hereof, among the Borrower, the lenders
from time to time parties thereto and NationsBank, N.A., as agent (as amended,
supplemented or otherwise modified, the "Additional Credit Agreement"). Subject
to the terms and conditions of this Amendment, the Lenders and the Agent have
agreed to so amend the Existing Credit Agreement.

         NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Borrower, the Lenders and the Agent hereby agree as follows:

         1. Amendment. The Existing Credit Agreement is hereby amended as
follows:

            (a) Section 1.1 is hereby amended by adding the following
    definitions:

            "'Additional Credit Agreement': that certain Credit Agreement, dated
            April 12, 1999, among the Borrower, the lenders from time to time
            parties thereto, and NationsBank, N.A., as agent for the lenders, as
            amended, supplemented or otherwise modified from time to time."

            "'Additional Loan Documents': the "Loan Documents", as defined under
            the Additional Credit Agreement.

            "'Additional Loans': the loans made under the Additional Credit
            Agreement."

            (b) Section 1.1 is hereby amended by deleting from the definition of
    "Investors" the phrase "Derrycroft Enterprises, Inc., a Delaware
    corporation; FIMA
<PAGE>   2
    Finance Management Inc., a British Virgin Islands corporation;" and
    substituting in lieu thereof the phrase "EXOR Group, a Luxembourg investment
    holding company; EXOR America Inc., a Delaware corporation;".

            (c) Section 3.8(d) is hereby amended by inserting the words "Loan
    Documents, the Additional" after the word "Leases,".

            (d) Section 5.2(g) is hereby amended by deleting the reference to
    "this Section 5.3(g)" and substituting in lieu thereof the words "this
    Section 5.2(g)".

            (e) Section 5.6(b) is hereby amended by deleting such clause (b) and
    substituting in lieu thereof a new clause (b) to read in its entirety as
    follows:

            "(b) In the event that any portion of any Property is so damaged,
            destroyed or lost, and such damage, destruction or loss is covered,
            in whole or in part, by insurance described in Section 5.5, then,
            (i) if no Event of Default has occurred and is continuing and the
            amount of Net Proceeds received (or reasonably anticipated by the
            Borrower to be received) in connection with such damage, destruction
            or loss is less than $50,000,000, then the Borrower may retain such
            Net Proceeds and, at the Borrower's option, apply such Net Proceeds
            to the restoration, replacement or rebuilding, in whole or in part,
            of the portion of such Property so damaged, destroyed or lost or to
            the prepayment of the Loans and, to the extent that the Loans have
            been paid in full, the Additional Loans, provided, however, that the
            Borrower shall be required to apply such Net Proceeds to the
            prepayment of the Loans (x) if the Borrower shall have failed to
            commence the restoration, replacement or rebuilding, in whole or in
            part, of the portion of such Property so damaged, destroyed or lost
            within six months following the receipt of such Net Proceeds or (y)
            if the Borrower shall cease to be diligently continuing such
            restoration, replacement or rebuilding, in the case of each of (x)
            and (y), subject to force majeure; or (ii) if no Event of Default
            has occurred and is continuing and the amount of Net Proceeds
            received (or reasonably anticipated by the Borrower to be received)
            in connection with such damage, destruction or loss is $50,000,000
            or greater, then the Borrower shall cause such Net Proceeds to be
            deposited in a segregated account at a bank (which need not be a
            Lender) selected by the Borrower, and the Borrower hereby covenants
            and agrees that such Net Proceeds shall be withdrawn from such
            segregated account and applied solely for the purpose of, and in the
            amounts necessary to, make required payments in connection with the
            restoration, replacement or rebuilding, in whole or in part, of the
            portion of such Property so damaged, destroyed or lost or to the
            prepayment of the Loans and, to the extent the Loans have been paid
            in full, the Additional Loans, provided, however, that the Borrower
            shall be required to apply such Net Proceeds to the prepayment of
            the Loans (x) if the Borrower shall have failed to commence the
            restoration, replacement or rebuilding, in whole or in part, of the
            portion of such Property so damaged, destroyed or lost within six
            months following the receipt of such Net Proceeds or (y) if the
            Borrower shall cease to


                                      -2-

            be diligently continuing such restoration, replacement or
            rebuilding, in the case of each of (x) and (y), subject to force
            majeure."

            (f) Section 5.6(d) is hereby amended by deleting such clause (d) and
    substituting in lieu thereof a new clause (d) to read in its entirety as
    follows:

                "(d) In the event of any condemnation of any Property or any
            part or interest therein or any similar event with respect thereto,
            then, (i) if no Event of Default has occurred and is continuing and
            the amount of Net Proceeds received (or reasonably anticipated by
            the Borrower to be received) in connection with such condemnation or
            similar event is less than $50,000,000, then the Borrower may retain
            such Net Proceeds and, at the Borrower's option, apply such Net
            Proceeds to the replacement, in whole or in part, of such Property
            or such part thereof so condemned or to the prepayment of the Loans
            and, to the extent the Loans have been paid in full, the Additional
            Loans, provided, however, that the Borrower shall be required to
            apply such Net Proceeds to the prepayment of the Loans (x) if the
            Borrower shall have failed to commence the replacement of such
            Property or such part thereof so condemned within six months
            following the receipt of such Net Proceeds or (y) if the Borrower
            shall cease to be diligently continuing such replacement, in the
            case of each of (x) and (y), subject to force majeure; or (ii) if no
            Event of Default has occurred and is continuing and the amount of
            Net Proceeds received (or reasonably anticipated by the Borrower to

         CREDIT AGREEMENT, dated as of April 12, 1999, among RCPI TRUST, a
Delaware business trust (the "Borrower"), the lenders from time to time parties
to this Agreement (the "Lenders"), NATIONSBANK, N.A., a national banking
association, as agent for the Lenders hereunder and BANKBOSTON, N.A., a national
banking association, as co-agent for the Lenders hereunder.

                                    RECITALS

         The Borrower was formed to take title to certain real and personal
property constituting a portion of the twelve buildings in New York City known
as Rockefeller Center, pursuant to the Second Amended Joint Plan of
Reorganization, confirmed on May 29, 1996, in the bankruptcy cases of RCP
Associates, a New York limited partnership, and Rockefeller Center Properties, a
New York general partnership. Pursuant to the Agreement and Plan of Merger,
dated as of November 7, 1995, as amended (the "Merger Agreement"), among
Rockefeller Center Properties, Inc. ("Old RCPI"), predecessor by merger to
Rockefeller Center Properties, Inc., a Delaware corporation, the surviving
entity of the merger of Old RCPI with and into RCPI Holdings, Inc., a Delaware
corporation (such surviving entity, "Holdings" or "RCPI"), RCPI Merger, Inc., a
Delaware corporation ("RCPI Merger"), and certain investors party thereto, RCPI
Merger was merged with and into RCPI effective July 10, 1996, after giving
effect to which RCPI was a wholly-owned subsidiary of Holdings. Each of RCPI and
RCPI Investors LLC, a Delaware limited liability company (the "LLC"), are the
owners of approximately 50% in beneficial interest in the Borrower. The Borrower
has assumed substantially all of the liabilities of RCPI. Pursuant to the
Existing Senior Credit Agreement (as hereinafter defined), certain lenders have
made available a loan facility to the Borrower in an original aggregate
principal amount of $100,000,000, under which $80,000,000 aggregate principal
amount of loans is outstanding as of the date hereof, which will be reduced to
$73,750,000 on March 31, 1999. The Borrower has requested that each of the
Lenders make one or more term loans to the Borrower in one or more advances, in
an aggregate principal amount not to exceed $47,000,000, the proceeds of which
would be used to fund budgeted tenant work allowances and leasing commissions,
to fund capital improvements to the Properties, to fund scheduled amortization
payments under the Existing Senior Credit Agreement, and for other general
working capital purposes of the Borrower.

         The Lenders are willing to make such term loans available to the
Borrower, but only on the terms, and subject to the conditions, set forth in
this Agreement.

         Accordingly, the parties hereto hereby agree as follows:

         SECTION 1. DEFINITIONS

         1.1 Defined Terms. As used in this Agreement, the following terms
shall have the following meanings:

                                      -1-

          2.11(e).

               "Adjusted Debt Service Coverage Ratio": for any period, the Debt
          Service Coverage Ratio for such period excluding, however, from the
          calculation of such Debt Service Coverage Ratio any principal and
          interest to be paid with respect to the Loans.

               "Adjusted Net Operating Income": for any Test Period, Net
          Operating Income for such period minus the Stabilized Capital

          control with, such Person. For purposes of this definition, "control"
          of a Person (including, with its correlative meanings, "controlled by"
          and "under common control with") means the power, directly or
          indirectly, either to (a) vote 10% or more of the securities having
          ordinary voting power for the election of directors of such Person or
          (b) direct or cause the direction of the management and policies of
          such Person, whether by contract or otherwise.

               "Agent": NationsBank, N.A., together with its affiliates, as the
          arranger of the Commitments and as the agent for the Lenders under
          this Agreement and the other Loan Documents. For purposes of
          clarification, the Co-Agent shall not be deemed the "Agent" for any
          purpose hereunder.

               "Agreement": this Credit Agreement, as amended, supplemented or
          otherwise modified from time to time.

               "Air Rights": the excess, if any, of the maximum permissible
          floor area of buildings now or hereafter available for "as of right"
          development of buildings on the portion of the Properties described as
          "Remaining Property" on Schedule 1.1(a) annexed hereto, together with
          all buildings and improvements thereon and all rights appurtenant
          thereto, without regard to the landmark status of the improvements
          thereon, over the current as-built floor area of the improvements
          erected on such parcel, all determined in accordance with the
          applicable provisions of the Zoning Resolution, and including, without
          limitation, the development rights specified in the Special Permit. As
          used in this definition, "Special Permit" means that certain special
          permit granted by the City Planning Commission of The City of New York
          (Permit No. C 890639 ZSM), as amended, renewed or replaced from time
          to time; and "Zoning Resolution" means the Zoning Resolution of The

          City Planning Commission pursuant to Section 200 of the New York City
          Charter.

               "Allocated Loan Amount": with respect to any Property, the amount
          set forth opposite the name of such Property on Schedule 1.1(a);
          provided, however, that the Allocated Loan Amount of each Property
          shall be reduced on and as of the date of any scheduled payment of
          principal of the Loans or any optional or mandatory prepayment


                                      -2-
<PAGE>   8

          of the Loans (other than any mandatory prepayment made pursuant to
          Section 2.11(a) in connection with any Release, but only to the extent
          of the Allocated Loan Amount(s) of the Property or Properties (or
          portions thereof) being released) by an amount equal to the amount of
          such payment or prepayment multiplied by a fraction, the numerator of
          which shall be such Allocated Loan Amount immediately prior to such
          reduction and the denominator of which shall be the aggregate of all
          Allocated Loan Amounts of all Properties owned by the Borrower
          immediately prior to such reduction; provided, further, however, that
          for purposes of determining any reduction of any Allocated Loan
          Amount, if a Release shall occur on the same date as any payment or
          prepayment of the Loans which would require a reduction in Allocated
          Loan Amounts pursuant to the immediately preceding proviso, such
          Release shall be deemed to occur prior to such payment or prepayment
          and prior to such reduction in Allocated Loan Amounts; and provided,
          further, however, that, with respect to the Release of any portion of
          any Property, (i) the Allocated Loan Amount of such Property shall be
          allocated ratably between the portion of such Property subject to such
          Release and the portion of such Property not subject to such Release
          by the Agent in good faith based upon such factors as, without
          limitation, the respective square footages and loan to value ratios of
          such portions of such Property and the contractual rents attributable
          to such portions of such Property, and such allocated amount shall be
          deemed the "Allocated Loan Amount" for each such portion of such
          Property, and (ii) from and after such Release, the portion of such
          Property which was not subject to such Release shall be deemed to be a
          "Property" for all purposes hereof.

               "Applicable Lending Office": for each Lender and for each Type of
          Loan, the lending office of such Lender designated for such Type of
          Loan on Schedule I hereto (or any other lending office from time to
          time notified to the Agent by such Lender ) as the office at which its
          Loans of such Type are to be made and maintained.

               "Applicable Margin": for any Loan of any Type at any time, the
          rate per annum set forth under the relevant column heading set forth

          SECTION 2. AMOUNT AND TERMS OF COMMITMENTS

               2.1 Commitments. Subject to the terms and conditions hereof, each
          Lender severally agrees to make one or more term loans (each, a
          "Loan") to the Borrower from time to time during the Commitment Period
          in an aggregate principal amount not to exceed the amount of the
          Commitment of such Lender then in effect; provided, that the
          Commitments shall terminate at 3:00 p.m., Dallas, Texas time, on May
          9, 1999, if the initial Loans have not been made prior to that time;
          and provided, further, that the Borrower shall not request Loans more
          frequently than once per calendar month; and provided, further, that
          after giving effect to the making of any Loans on any Borrowing Date
          occurring on or after any date set forth in the table on Schedule 2.2,
          the aggregate outstanding principal amount of Loans may in no event
          exceed the amount set forth on such table opposite such date as the
          "Maximum Allowable Loan Balance". The Loans may from time to time be
          (a) Eurodollar Loans, (b) Base Rate Loans or (c) a combination
          thereof, as determined by the Borrower and notified to the Agent in
          accordance with Sections 2.3 and 4.2. Amounts repaid on account of the
          Loans may not be reborrowed.

               2.2 Notes. The Loans of each Lender shall be evidenced by a
          promissory note of the Borrower, substantially in the form of Exhibit
          A with appropriate insertions as to


                                      -20-
<PAGE>   26

          payee, date and principal amount (a "Note"), payable to the order of
          such Lender and representing the obligation of the Borrower to pay a
          principal amount equal to the lesser of (a) the amount of the
          Commitment of such Lender and (b) the aggregate unpaid principal
          amount of all Loans made by such Lender. Each Lender is hereby
          authorized to record the date, Type and amount of its Loans and the
          date and amount of each payment or prepayment of principal thereof on
          the schedule annexed to and constituting a part of its Note, and any
          such recordation shall constitute prima facie evidence of the accuracy
          of the information so recorded absent manifest error; provided, that
          the failure of such Lender to make any such recordation shall not
          impair or otherwise affect the validity or enforceability of its Note.
          Each Note shall (a) be dated the Closing Date, (b) be stated to mature
          in installments in amounts equal to such Lender's Commitment
          Percentage of the amounts, and payable on the dates, set forth, or
          determined as set forth, on Schedule 2.2, and (c) bear interest for
          the period from the date thereof on the unpaid principal amount
          thereof at the applicable interest rates per annum specified in
          Section 2.7. Interest on the Notes shall be payable on the dates
          specified in Section 2.7(d).

               2.3 Procedure for Borrowing. The Borrower may borrow under the
          Commitments during the Commitment Period on any Business Day in an
          aggregate principal amount not exceeding the aggregate Available
          Commitments then in effect; provided, that the Borrower shall give the
          Agent irrevocable notice (which notice must be received by the Agent
          prior to 10:00 a.m., Dallas, Texas time, (a) three Business Days prior
          to the requested Borrowing Date, if all or any part of the Loans are
          to be initially Eurodollar Loans or (b) one Business Day prior to the
          requested Borrowing Date, otherwise) requesting that the Lenders make
          the Loans on such requested Borrowing Date and specifying (i) the
          amount to be borrowed, (ii) the requested Borrowing Date, (iii)
          whether the borrowing is to be of Eurodollar Loans or Base Rate Loans
          or a combination thereof, (iv) if the Loans are to be entirely or
          partly Eurodollar Loans, the amounts of such Type of Loan and the
          lengths of the initial Interest Periods therefor, and (v) the
          certificate required pursuant to Section 4.2(c). The initial borrowing
          shall be in an amount equal to at least $5,000,000. Each borrowing
          thereafter under the Commitments shall be in an amount equal to at
          least $1,000,000. Upon receipt of such notice the Agent shall promptly
          notify each Lender thereof. Each Lender will make the amount of its
          pro rata share of each borrowing available to the Agent for the
          account of the Borrower at the office of the Agent specified in
          Section 9.2 prior to 11:00 a.m., Dallas, Texas time, on the Borrowing
          Date requested by the Borrower in funds immediately available to the
          Agent. Such borrowing will then be made available to the Borrower by
          the Agent by wire transfer to an account designated by the Borrower in
          writing with the aggregate of the amounts made available to the Agent
          by the Lenders and in like funds as received by the Agent.

               2.4 [Intentionally Omitted].

               2.5 Termination or Reduction of Commitments. The Borrower shall
          have the right at any time during the Commitment Period, upon not less
          than five Business Days' notice to the Agent, to terminate the
          Commitments or, from time to time, to reduce the amount of the
          Commitments. Any such reduction shall be in an amount equal to
          $1,000,000 or a whole multiple thereof and shall reduce permanently
          the Commitments then in effect.

         2.6 Extension of Maturity Date. The Borrower may, at its option and
subject to the satisfaction of the conditions precedent set forth in the next
succeeding sentence, on a single occasion request that the Maturity Date as in
effect on the date of this Agreement (the "Original Maturity Date") be extended
to December 31, 2000 (such new date, the "New Maturity Date"). The effectiveness
of the extension of the Original Maturity Date to the New Maturity Date shall be
subject to the satisfaction of the following conditions precedent on and as of
the Original Maturity Date:

               (a) the Borrower shall have provided written notice to the Agent,
          at least 30 days but no more than 90 days prior to the Original
          Maturity Date, that it has elected to extend the Original Maturity
          Date to the New Maturity Date, which notice shall contain a
          certification from a Responsible Officer of the Borrower that as of
          the date of such notice the Borrower shall be able to satisfy each of
          the other conditions precedent to the extension of the Maturity Date
          set forth in this Section 2.6 and shall include computations, in
          reasonable detail, supporting the assertion that the Borrower shall be
          able to satisfy the conditions set forth in clauses (d) and (e) of
          this Section 2.6;

               (b) the Borrower shall not have received written notice from the
          Agent of any Default;

               (c) no Event of Default shall have occurred and be continuing;

               (d) the Debt to Value Ratio (based upon the appraisal delivered
          pursuant to Section 5.2(g)) shall not exceed 65%;

               (e) the Debt Service Coverage Ratio for the Test Period ended
          December 31, 1999 shall not be less than 1.15 to 1;

               (f) the Adjusted Debt Service Coverage Ratio for the Test Period
          ended December 31, 1999 shall not be less than 1.55 to 1;

               (g) the Borrower shall have obtained an interest rate swap, cap,
          collar or other interest rate hedge with respect to at least 50% of
          the then outstanding principal amount of the Loans, fixing the
          Eurodollar Rate for the Extension Term at not more than 3% above the
          Eurodollar Rate as in effect on the Original Maturity Date; and

               (h) the Borrower shall have paid an extension fee (the "Extension
          Fee"), in an amount equal to 0.25% of the aggregate principal amount
          of the Loans then outstanding, to the Agent for the ratable benefit of
          the Lenders.

From and after the effectiveness of any such extension as provided in this
Section 2.6, the New Maturity Date shall constitute the Maturity Date for all
purposes of the Loan Documents.

         2.7 Interest Rates and Payment Dates. (a) Each Eurodollar Loan shall
bear interest for each day during each Interest Period (excluding the last day
of each Interest Period) with respect thereto at a rate per annum equal to the
Eurodollar Rate determined for such day plus the Applicable Margin.

                                      -22-
<PAGE>   28

               (b) Each Base Rate Loan shall bear interest at a rate per annum
          equal to the Base Rate plus the Applicable Margin.


               (c) If any Event of Default shall have occurred and be
          continuing, the principal of the Loans and any interest, commitment
          fee or other amount shall bear interest during the period such Event
          of Default continues at a rate per annum which is the higher of (A)
          (x) in the case of principal, the rate that would otherwise be
          applicable thereto pursuant to the foregoing provisions of this
          Section plus 2% or (y) in the case of any such overdue interest,
          commitment fee or other amount, the rate described in paragraph (b) of
          this Section plus 2%, and (B) the rate at which interest accrues on
          overdue amounts payable under the Zeros in each case from the date of
          such non-payment until such overdue principal, interest, commitment
          fee or other amount is paid in full (as well after as before
          judgment), but in no event in excess of the maximum amount permitted
          by applicable law.

               (d) Interest shall be payable in arrears on each Interest Payment
          Date, provided that interest accruing pursuant to paragraph (c) of
          this Section shall be payable from time to time on demand.

         2.8 Conversion and Continuation Options. (a) The Borrower may elect
from time to time to Convert Eurodollar Loans to Base Rate Loans, by giving the
Agent at least two Business Days' prior irrevocable notice of such election,
provided that any such Conversion of Eurodollar Loans may only be made on the
last day of an Interest Period with respect thereto. The Borrower may elect from
time to time to Convert Base Rate Loans to Eurodollar Loans by giving the Agent
at least three Business Days' prior irrevocable notice of such election. Any
such notice of Conversion to Eurodollar Loans shall specify the length of the
initial Interest Period or Interest Periods therefor. Upon receipt of any such
notice the Agent shall promptly notify each Lender thereof. All or any part of
outstanding Eurodollar Loans and Base Rate Loans may be Converted as provided
herein, provided that (i) no Loan may be Converted into a Eurodollar Loan when
any Event of Default has occurred and is continuing and the Agent has determined
or the Required Lenders have notified the Agent of their determination that such
a Conversion is not appropriate, (ii) any such Conversion may only be made if,
after giving effect thereto, Section 2.9 shall not have been contravened, and
(iii) no Loan may be converted into a Eurodollar Loan after the date that is one
month prior to the Maturity Date.

               (b) Any Eurodollar Loans may be Continued as such upon the
          expiration of the then current Interest Period with respect thereto by
          the Borrower giving notice to the Agent, in accordance with the
          applicable provisions of the term "Interest Period" set forth in
          Section 1.1, of the length of the next Interest Period to be
          applicable to such Loans, provided that no Eurodollar Loan may be
          Continued as such (i) when any Event of Default has occurred and is
          continuing and the Agent has determined or the Required Lenders have
          notified the Agent of their determination that such a Continuation is
          not appropriate, (ii) if, after giving effect thereto, Section 2.9
          would be contravened or (iii) after the date that is one month prior
          to the Maturity Date and provided, further, that if the Borrower shall
          fail to give such notice or if such Continuation is not permitted such


                                      -23-
<PAGE>   29

          Loans shall be automatically converted to Base Rate Loans on the last
          day of such then expiring Interest Period.

         2.9 Minimum Amounts and Maximum Number of Tranches. All borrowings,
Conversions and Continuations of Loans hereunder and all selections of Interest
Periods hereunder shall be in such amounts and be made pursuant to such
elections so that, after giving effect thereto, the aggregate principal amount
of the Loans comprising each Tranche shall be equal to $1,000,000 or a whole
multiple of $250,000 in excess thereof. In no event shall there be more than
four Tranches outstanding at any time.


         2.10 Optional Prepayments. The Borrower may at any time and from time
to time, prepay the Loans, in whole or in part, without premium or penalty, upon
at least four Business Days' irrevocable notice to the Agent, specifying the
date and amount of prepayment and whether the prepayment is of Eurodollar Loans,
Base Rate Loans or a combination thereof, and, if of a combination thereof, the
amount allocable to each. Upon receipt of any such notice the Agent shall
promptly notify each Lender thereof. If any such notice is given, the amount
specified in such notice shall be due and payable on the date specified therein,
together with any amounts payable pursuant to Section 2.18 and accrued interest
to such date on the amount prepaid. Partial prepayments of the Loans pursuant to
this Section shall be applied to the installments of principal thereof in the
direct order of their scheduled maturities. Amounts prepaid on account of the
Loans may not be reborrowed. Partial prepayments pursuant to this Section shall
be in an aggregate principal amount of $100,000 or a whole multiple thereof.

         2.11 Mandatory Prepayments.

          (a) (i) Upon the date of any Release of any Property (or portion
     thereof) other than the Air Rights, the Borrower shall prepay the Loans in
     an amount equal to the Release Price of such Property (or portion thereof),
     and (ii) upon the sale or other disposition of the Air Rights, the Borrower
     shall prepay the Loans in an amount equal to the excess, if any, of 10% of
     the Net Proceeds of such sale over the aggregate amount of prepayments of
     the Existing Loans required to be made pursuant to Section 2.11(a)(ii) of
     the Existing Senior Credit Agreement in respect of such sale or
     disposition.

          (b) To the extent required to be applied to the prepayment of the
     Loans pursuant to Section 5.6, unless the Required Lenders otherwise agree,
     the Borrower shall prepay the Loans in an amount equal to the excess, if
     any, of 100% (or such smaller portion as required pursuant to Section 5.6)
     of the Net Proceeds of any destruction, casualty or taking of any property
     of the Borrower or any Subsidiary (including any insurance proceeds) over
     the aggregate amount of prepayments of the Existing Loans required to be
     made pursuant to Section 2.11(b) of the Existing Senior Credit Agreement in
     respect of such destruction, taking or casualty, in any such case no later
     than three Business Days following receipt by the Borrower or such
     Subsidiary of such proceeds, together with accrued interest to such date on
     the amount prepaid.

                                      -24-
<PAGE>   30

          (c) Prepayments of Loans pursuant to Section 2.11(a) and (b) shall be
     applied pro rata to the installments of the Loans and such amounts so
     prepaid may not be reborrowed. Prepayments of Loans pursuant to this
     Section 2.11 (other than Section 2.11(a) and (b)) shall be applied to the
     installments of the Loans in the inverse order of maturity and such amounts
     so prepaid may not be reborrowed.

          (d) Nothing in Section 2.11(a) shall be construed to derogate any
     restriction or limitation contained in any Loan Document imposed on any
     transaction of the types described in Section 2.11(a), including without
     limitation the restrictions and limitations set forth in Sections 6.1, 6.4
     and 6.5 hereof.

          (e) If, on the last day of any fiscal quarter of the Borrower
     (commencing with second quarter of 1999), either (i) the Debt Service
     Coverage Ratio for the Test Period ended on such day was less than 1.15 to
     1 or (ii) the Adjusted Debt Service Coverage Ratio for the Test Period
     ended on such day was less than 1.40 to 1, the Borrower shall prepay the
     Loans in an amount equal to the excess, if any, of the 14% Debenture
     Quarterly Amount for the 14% Debenture Interest Payment Date next occurring
     after the last day of such quarter over the aggregate amount of prepayments
     of the Existing Loans required pursuant to Section 2.11(e) of the Existing
     Senior Credit Agreement in respect of such fiscal quarter (any such
     prepayment pursuant to this Section 2.11(e), an "Accelerated Amortization
     Payment").

     Such calculations of Debt Service Coverage Ratio (or Adjusted Debt Service
     Coverage Ratio) for any such Test Period shall be made on the date the
     Estimated Calculation for such Test Period is required to be delivered to
     the Agent pursuant to Section 5.2(h), and the Borrower shall make any such
     prepayment required by this Section 2.11(e) based upon such Estimated
     Calculation. If, on the date that the financial statements for the fiscal
     quarter ended on the last day of such Test Period are delivered to the
     Agent pursuant to Section 5.1(a) or (b), the amounts calculated for Debt
     Service Coverage Ratio (or Adjusted Debt Service Coverage Ratio) for such
     Test Period based upon such financial statements would have resulted in a
     determination that a prepayment is or is not required under Section 2.11(e)
     that is different from the determination resulting from the Estimated
     Calculation, on the date of delivery of such financial statements the
     Borrower shall make such prepayment, or the Lenders shall as soon as
     reasonably practicable after such delivery of such financial statements
     return to the Borrower the prepayment made pursuant to such Estimated
     Calculation, as the case may be, so that the prepayment made by the
     Borrower for such Test Period is the prepayment required under this Section
     2.11(e) based upon the calculation of Debt Service Coverage Ratio (or
     Adjusted Debt Service Coverage Ratio)for such Test Period determined with
     reference to such financial statements delivered pursuant to Section 5.1(a)
     or (b).

         2.12 Computation of Interest and Fees. (a) Commitment fees and interest
shall be calculated on the basis of a 360-day year for the actual days elapsed.
The Agent shall as soon as practicable notify the Borrower and the Lenders of
each determination of a Eurodollar Rate. Any change in the interest rate on a
Loan resulting from a change in the Base Rate or the Eurocurrency Reserve
Requirements shall become effective as of the opening of


                                      -25-
<PAGE>   31

business on the day on which such change becomes effective. The Agent shall as
soon as practicable notify the Borrower and the Lenders of the effective date
and the amount of each such change in interest rate.

         (b) Each determination of an interest rate by the Agent pursuant to any
provision of this Agreement shall be conclusive and binding on the Borrower and
the Lenders in the absence of manifest error. The Agent shall, at the request of
the Borrower, deliver to the Borrower a statement showing the quotations used by
the Agent in determining any interest rate pursuant to Section 2.7(a).

         2.13 Inability to Determine Interest Rate. If prior to the first day of
any Interest Period for a Eurodollar Loan:

         (a) the Agent shall have determined (which determination shall be
     conclusive and binding upon the Borrower) that, by reason of circumstances
     affecting the relevant market, adequate and reasonable means do not exist
     for ascertaining the Eurodollar Rate for such Interest Period, or

         (b) the Agent shall have received notice from the Majority Lenders
     that the Eurodollar Rate determined or to be determined for such Interest
     Period will not adequately and fairly reflect the cost to such Lenders (as
     conclusively certified by such Lenders) of making or maintaining their
     affected Loans during such Interest Period,

the Agent shall give telecopy or telephonic notice thereof to the Borrower and
the Lenders as soon as practicable thereafter. If such notice is given (x) any
Eurodollar Loans requested to be made on the first day of such Interest Period
shall be made as Base Rate Loans, and (y) any outstanding Eurodollar Loans shall
be Converted, on the first day of such Interest Period, to Base Rate Loans.
Until such notice has been withdrawn by the Agent, no further Eurodollar Loans
shall be made or Continued as such.

         2.14 Pro Rata Treatment and Payments. (a) Each borrowing by the
Borrower from the Lenders hereunder, each payment by the Borrower on account of
any commitment fee hereunder and any reduction of the Commitments of the Lenders
shall be made pro rata according to the respective Commitment Percentages, as
applicable, of the Lenders. Each payment (including each prepayment) by the
Borrower on account of principal of and interest on the Loans shall be made pro
rata according to the respective outstanding principal amounts of the Loans then
held by the Lenders. All payments (including prepayments) to be made by the
Borrower hereunder, whether on account of principal, interest, fees or
otherwise, shall be made without set-off or counterclaim and shall be made prior
to 12:00 noon, Dallas, Texas time, on the due date thereof to the Agent, for the
account of the Lenders, at the Agent's office specified in Section 9.2, in
Dollars and in immediately available funds. The Agent shall distribute such
payments to the Lenders promptly upon receipt in like funds as received. If any
payment hereunder (other than payments on Eurodollar Loans) becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day, and, with respect to payments of principal,
interest thereon shall be payable at the then applicable rate during such
extension. If


                                      -26-
<PAGE>   32

any payment on a Eurodollar Loan becomes due and payable on a day other than a
Business Day, the maturity thereof shall be extended to the next succeeding
Business Day unless the result of such extension would be to extend such payment
into another calendar month in which event such payment shall be made on the
immediately preceding Business Day.

          (b) Unless the Agent shall have been notified in writing by any Lender
     prior to a borrowing that such Lender will not make the amount that would
     constitute its Commitment Percentage of such borrowing available to the
     Agent, the Agent may assume that such Lender is making such amount
     available to the Agent, and the Agent may, in reliance upon such
     assumption, make available to the Borrower a corresponding amount. If such
     amount is not made available to the Agent by the required time on the
     Borrowing Date therefor, such Lender shall pay to the Agent, on demand,
     such amount with interest thereon at a rate equal to the daily average
     Federal Funds Effective Rate for the period until such Lender makes such
     amount immediately available to the Agent. A certificate of the Agent
     submitted to any Lender with respect to any amounts owing under this
     Section shall be conclusive in the absence of manifest error. If such
     Lender's Commitment Percentage of such borrowing is not made available to
     the Agent by such Lender within three Business Days of such Borrowing Date,
     the Agent shall also be entitled to recover, without duplication of
     interest paid by such Lender pursuant to the second preceding sentence,
     such amount with interest thereon at the rate per annum applicable to Base
     Rate Loans hereunder, on demand, from the Borrower.

         2.15 Illegality. Notwithstanding any other provision herein, if the
adoption of or any change in any Requirement of Law or in the interpretation or
application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such
Lender hereunder to make Eurodollar Loans and Continue Eurodollar Loans as such
shall forthwith be canceled and (b) such Lender's Loans then outstanding as
Eurodollar Loans, if any, shall be Converted automatically to Base Rate Loans on
the respective last days of the then current Interest Periods with respect to
such Loans or within such earlier period as required by law. If any such
Conversion of a Eurodollar Loan occurs on a day which is not the last day of the
then current Interest Period with respect thereto, the Borrower shall pay to
such Lender such amounts, if any, as may be required pursuant to Section 2.18.

         2.16 Requirements of Law. (a) If the adoption of or any change in any
Requirement of Law or in the interpretation or application thereof or compliance
by any Lender with any request or directive (whether or not having the force of
law) from any central bank or other Governmental Authority, in any such case,
made subsequent to the date hereof:

          (i) shall subject any Lender to any tax of any kind whatsoever with
     respect to this Agreement, any Note or any Eurodollar Loan made by it, or
     change the basis of taxation of payments to such Lender in respect thereof
     (except for Non-Excluded Taxes covered by Section 2.17 and changes in the
     rate of tax on the overall net income of such Lender);

                                      -27-
<PAGE>   33

          (ii) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender which is not otherwise included in the determination
     of the Eurodollar Rate hereunder; or

          (iii) shall impose on any Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, Continuing or
maintaining Eurodollar Loans or to reduce any amount receivable hereunder in
respect thereof, then, in any such case, the Borrower shall promptly pay such
Lender, upon its written demand, such additional amount or amounts as will
compensate such Lender for such increased cost or the amount by which such
amount received is reduced.

          (b) If any Lender shall have determined that the adoption of or any
     change in any Requirement of Law regarding capital adequacy or in the
     interpretation or application thereof or compliance by such Lender or any
     corporation controlling such Lender with any request or directive regarding
     capital adequacy (whether or not having the force of law) from any
     Governmental Authority, in any such case, made subsequent to the date
     hereof shall have the effect of reducing the rate of return on such
     Lender's or such corporation's capital as a consequence of its obligations
     hereunder to a level below that which such Lender or such corporation could
     have achieved but for such adoption, change or compliance (taking into
     consideration such Lender's or such corporation's policies with respect to
     capital adequacy) by an amount deemed by such Lender to be material, then
     from time to time, the Borrower shall, subject to paragraph (c) below and
     Section 2.20, promptly pay to such Lender such additional amount or amounts
     as will compensate such Lender for such reduction.

          (c) If any Lender becomes entitled to claim any additional amounts
     pursuant to this Section, it shall promptly notify the Borrower (with a
     copy to the Agent) of the event by reason of which it has become so
     entitled. A certificate as to any additional amounts payable pursuant to
     this Section submitted by such Lender to the Borrower (with a copy to the
     Agent) shall be conclusive in the absence of manifest error. The agreements
     in this Section shall survive the termination of this Agreement and the
     payment of the Loans and all other amounts payable hereunder.

          (d) Any amount payable by the Borrower on account of this Section 2.16
     shall not be duplicative of any amounts payable under Sections 2.17 or 2.18
     or included in the calculation of Eurodollar Rate.


         2.17 Taxes. (a) All payments made by the Borrower under this Agreement
and any Notes shall be made free and clear of, and without deduction or
withholding for or on account of, any present or future income, stamp or other
taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now
or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding net income taxes and franchise


                                      -28-
<PAGE>   34

taxes (imposed in lieu of net income taxes) imposed on the Agent or any Lender
as a result of a present or former connection between the Agent or such Lender
and the jurisdiction of the Governmental Authority imposing such tax or any
political subdivision or taxing authority thereof or therein (other than any
such connection arising solely from the Agent or such Lender having executed,
delivered or performed its obligations or received a payment under, or enforced,
this Agreement or any Note). If any such non-excluded taxes, levies, imposts,
duties, charges, fees deductions or withholdings ("Non-Excluded Taxes") are
required to be withheld from any amounts payable to the Agent or any Lender
hereunder or under any Note, the amounts so payable to the Agent or such Lender
shall be increased to the extent necessary to yield to the Agent or such Lender
(after payment of all Non-Excluded Taxes) interest or any such other amounts
payable hereunder at the rates or in the amounts specified in this Agreement,
provided, however, that the Borrower shall not be required to increase any such
amounts payable to any Lender that is not organized under the laws of the United
States of America or a state thereof if such Lender fails to comply with the
requirements of clause (b) of this Section. Whenever any Non-Excluded Taxes are
payable by the Borrower, as promptly as possible thereafter the Borrower shall
send to the Agent for its own account or for the account of such Lender, as the
case may be, a certified copy of an original official receipt received by the
Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded
Taxes when due to the appropriate taxing authority or fails to remit to the
Agent the required receipts or other required documentary evidence, the Borrower
shall indemnify the Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Agent or any Lender as a result of any
such failure. The agreements in this Section shall survive the termination of
this Agreement and the payment of the Loans and all other amounts payable
hereunder.

          (b) Each Lender that is not incorporated under the laws of the United
     States of America or a state thereof shall:

          (i) (A) if such Lender is a "bank" within the meaning of Section
     881(c)(3)(A) of the Code, deliver to the Borrower and the Agent (x) two
     duly completed copies of United States Internal Revenue Service Form 1001
     or 4224, or successor applicable form, as the case may be, and (y) an
     Internal Revenue Service Form W-8 or W-9, or successor applicable form, as
     the case may be, or (B) if such Lender is not a "bank" within the meaning
     of Section 881(c)(3)(A) of the Code and cannot deliver either Internal
     Revenue Service Form 1001 or 4224, deliver (x) a certificate substantially
     in the form of Exhibit B (a "Tax Status Certificate") and (y) two completed
     and signed copies of Internal Revenue Service Form W-8 or successor
     applicable form;

          (ii) deliver to the Borrower and the Agent two further copies of any
     such form or certification on or before the date that any such form or
     certification expires or becomes obsolete and after the occurrence of any
     event requiring a change in the most recent form previously delivered by it
     to the Borrower; and

          (iii) obtain such extensions of time for filing and complete such
     forms or certifications as may reasonably be requested by the Borrower or
     the Agent;

                                      -29-
<PAGE>   35

     unless in any such case an event (including, without limitation, any change
     in treaty, law or regulation) has occurred prior to the date on which any
     such delivery would otherwise be required which renders all such forms
     inapplicable or which would prevent such Lender from duly completing and
     delivering any such form with respect to it and such Lender so advises the
     Borrower and the Agent. Such Lender shall certify (i) in the case of a Form
     1001 or 4224, that it is entitled to receive payments under this Agreement
     without deduction or withholding of any United States federal income taxes,
     (ii) in the case of a Tax Status Certificate, that it is not a "bank" as
     such term is defined in Section 881(c)(3)(A) of the Code, and (iii) in the
     case of a Form W-8 or W-9, that it is entitled to an exemption from United
     States backup withholding tax. Each Person that shall become a Lender or a
     Participant pursuant to Section 9.6 shall, upon the effectiveness of the
     related transfer, be required to provide all of the forms and statements
     required pursuant to this Section, provided that in the case of a
     Participant such Participant shall furnish all such required forms and
     statements to the Lender from which the related participation shall have
     been purchased.

          (c) Any amount payable by the Borrower on account of this Section 2.17
     shall not be duplicative of any amounts payable under Sections 2.16 or 2.18
     or included in the calculation of Eurodollar Rate.

         2.18 Indemnity. The Borrower agrees to indemnify each Lender and to
hold each Lender harmless from any loss or expense which such Lender may sustain
or incur as a consequence of (a) default by the Borrower in making a borrowing
of or Continuation of Eurodollar Loans after the Borrower has given a notice
requesting the same in accordance with the provisions of this Agreement, (b)
default by the Borrower in making any prepayment after the Borrower has given a
notice thereof in accordance with the provisions of this Agreement or (c) the
making of a prepayment or Conversion of Eurodollar Loans on a day which is not
the last day of an Interest Period with respect thereto. Such indemnification
may include an amount equal to the excess, if any, of (i) the amount of interest
which would have accrued on the amount so prepaid or Converted, or not so
borrowed or Continued, for the period from the date of such prepayment or
Conversion or of such failure to borrow or Continue to the last day of such
Interest Period (or, in the case of a failure to borrow or Continue, the
Interest Period that would have commenced on the date of such failure) in each
case at the applicable rate of interest for such Loans provided for herein
(excluding, however, the Applicable Margin included therein, if any) over (ii)
the amount of interest (as reasonably determined by such Lender) which would
have accrued to such Bank on such amount by placing such amount on deposit for a
comparable period with leading banks in the interbank eurodollar market. Any
amount payable by the Borrower on account of this Section 2.18 shall not be
duplicative of any amounts payable under Sections 2.16 or 2.17 or included in
the calculation of Eurodollar Rate. This covenant shall survive the termination
of this Agreement and the payment of the Loans and all other amounts payable
hereunder.

         2.19 Lending Offices; Change of Lending Office. (a) Loans of each Type
made by any Lender shall be made and maintained at such Lender's Applicable
Lending Office for Loans of such Type.

                                      -30-
<PAGE>   36

          (b) Each Lender agrees that if it makes any demand for payment under
     Section 2.16 or 2.17(a), or if any adoption or change of the type described
     in Section 2.15 shall occur with respect to it, it will use reasonable
     efforts (consistent with its internal policy and legal and regulatory
     restrictions and so long as such efforts would not be disadvantageous to
     it, as determined in its sole discretion) to designate a different lending
     office if the making of such a designation would reduce or obviate the need
     for the Borrower to make payments under Section 2.16 or 2.17(a), or would
     eliminate or reduce the effect of any adoption or change described in
     Section 2.15.

         2.20 Certificates, Etc. (a) If requested by the Borrower, in connection
with any demand for payment pursuant to Sections 2.16, 2.17 or 2.18, a Lender
shall provide to the Borrower, with a copy to the Agent, a certificate setting
forth in reasonable detail the basis for such demand and the satisfaction of the
conditions set forth in the next succeeding sentence.

          (b) Anything to the contrary herein notwithstanding, no Lender shall
     have the right to demand any payment or compensation under Section 2.16 or
     2.17 (i) with respect to any period more than nine months prior to the date
     it has made a demand pursuant to such Sections, and (ii) to the extent that
     such Lender determines in good faith that the interest rate or margin on
     the relevant Loans appropriately accounts for the increased cost or reduced
     rate of return which is the subject of such demand.

         2.21 Replacement of Lenders. If no Default or Event of Default shall
have occurred and be continuing, the Borrower may replace any Lender (other than
NationsBank or any Affiliate thereof) that has requested the Borrower to pay
amounts pursuant to Sections 2.16 or 2.17 or the obligations of which to make
any Loans has been suspended pursuant to Section 2.15 (such Lender, an "Affected
Lender"), at any time until such Affected Lender's request for payment under
Section 2.16 or 2.17 has been withdrawn or such suspension of the obligation to
make Loans has ceased, by giving not less than 10 Business Days' notice to the
Agent (which shall promptly notify the Affected Lender and each other Lender)
that it intends to replace such Affected Lender with one or more Eligible
Assignees (or other lender acceptable to the Agent). Such replacement shall be
effected by Assignment and Acceptance and registration of such assignment in the
Register in accordance with Section 9.6(c). Upon the effective date of any such
replacement pursuant to this Section 2.21, and as a condition thereto, the
Borrower shall, or shall cause the replacement Lender or Lenders to, pay to the
Affected Lender being so replaced an amount equal to the entire outstanding
principal amount of such Affected Lender's Loans and any other amounts owing to
such Affected Lender hereunder (including, without limitation, interest, fees,
compensation and additional amounts under this Section 2, in each case accrued
to the effective date of such replacement), whereupon (i) each replacement
lender shall become a "Lender" for all purposes of this Agreement and the other
Loan Documents having a Commitment in the amount of such Affected Lender's
Commitment assumed by it, (ii) the Commitment of the Affected Lender being
replaced shall be terminated upon such effective date and (iii) the Affected
Lender shall cease to be a "Lender" as of such effective date.


         SECTION 3. REPRESENTATIONS AND WARRANTIES

                                      -31-
<PAGE>   37

         To induce the Agent and the Lenders to enter into this Agreement and to
make the Loans, the Borrower hereby represents and warrants to the Agent and
each Lender that:

         3.1 Financial Condition.

          (a) The balance sheet of the Borrower as at December 31, 1998 and the
     related statements of income and of cash flows for the fiscal year ended on
     such date, reported on by Arthur Andersen LLP, copies of which have
     heretofore been furnished to the Agent, are complete and present fairly the
     financial condition of the Borrower as at such date, and the results of its
     operations and its cash flows for the fiscal year then ended. All such
     financial statements, including the related schedules and notes thereto,
     have been prepared in accordance with GAAP applied consistently throughout
     the periods involved (except as approved by such accountants or Responsible
     Officer, as the case may be, and as disclosed therein). The Borrower did
     not have, at the date of the most recent balance sheet referred to above,
     any material Guarantee Obligation, contingent liability or liability for
     taxes, or any long-term lease (other than the Ground Leases, and other than
     leases with respect to which the Borrower is landlord) or unusual forward
     or long-term commitment, including, without limitation, any interest rate
     or foreign currency swap or exchange transaction or other financial
     derivative, which is not reflected in the foregoing statements or in the
     notes thereto. During the period from December 31, 1998 to and including
     the date hereof there has been no sale, transfer or other disposition by
     the Borrower of any material part of its business or property and no
     purchase or other acquisition of any business or property (including any
     Capital Stock of any other Person) material in relation to the financial
     condition of the Borrower at December 31, 1998.

          (b) The pro forma balance sheet of the Borrower as at March 31, 1999,
     certified by a Responsible Officer of the Borrower (the "Pro Forma Balance
     Sheet"), a copy of which has been provided to the Agent, is the unaudited
     balance sheet of the Borrower adjusted to give effect (as if such events
     had occurred on such date) to (i) the making of Loans in an aggregate
     principal amount of $47,000,000 and (ii) the payment of all fees and
     expenses related to the foregoing transaction, as estimated in good faith
     as of the date of the Pro Forma Balance Sheet. The Pro Forma Balance Sheet,
     together with the notes thereto, presents fairly, on a pro forma basis, the
     financial position of the Borrower as at March 31, 1999, assuming that the
     events specified in the preceding sentence had actually occurred on such
     date.

          (c) The operating forecast and cash flow projections of the Borrower,
     copies of which have heretofore been furnished to the Agent, were prepared
     in good faith under the direction of a Responsible Officer of the Borrower.

         3.2 No Change. (a) Since December 31, 1998 there has been no
development or event which has had or could reasonably be expected to have a
Material Adverse Effect, and (b) during the period from December 31, 1998 to and
including the date hereof no distributions have been declared, paid or made upon
the Capital Stock of the Borrower nor has any of the Capital Stock of the
Borrower been redeemed, retired, purchased


                                      -32-
<PAGE>   38

or otherwise acquired for value by the Borrower, any Investor or any of their
respective Affiliates or Subsidiaries.

         3.3 Existence; Compliance with Law. The Borrower (a) is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization, (b) has the power and authority, and the legal right, to own and
operate its property, to lease the property it operates as lessee and to conduct
the business in which it is currently engaged, (c) is duly qualified and in good
standing under the laws of each jurisdiction where its ownership, lease or
operation of property or the conduct of its business requires such qualification
and (d) is in compliance with all Requirements of Law except to the extent that
the failure to comply therewith could not, in the aggregate, reasonably be
expected to have a Material Adverse Effect.

         3.4 Power; Authorization; Enforceable Obligations. (a) The Borrower has
the power and authority, and the legal right, to make, deliver and perform the
Loan Documents to which it is a party and to borrow hereunder and has taken all
necessary action to authorize the borrowings on the terms and conditions of this
Agreement and any Notes and to authorize the execution, delivery and performance
of the Loan Documents to which it is a party. No consent or authorization of,
filing with, notice to or other act by or in respect of, any Governmental
Authority or any other Person is required in connection with the borrowings
hereunder or with the execution, delivery, performance, validity or
enforceability of the Loan Documents to which the Borrower is a party, except as
may have been obtained or made and is in full force and effect. This Agreement
has been, and each other Loan Document to which it is a party will be, duly
executed and delivered on behalf of the Borrower. This Agreement constitutes,
and each other Loan Document to which it is a party when executed and delivered
will constitute, a legal, valid and binding obligation of the Borrower
enforceable against the Borrower in accordance with its terms, subject to the
effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar laws relating to or affecting creditors' rights
generally, general equitable principles (whether considered in a proceeding in
equity or at law) and an implied covenant of good faith and fair dealing.

          (b) To the knowledge of Borrower, except as set forth on Schedule
     3.4(b), the Properties and the use thereof by the Borrower or any tenant of
     the Borrower comply in all material respects with (i) all applicable
     federal, state and local laws, ordinances, building codes, rules and
     regulations pertaining to zoning, building, subdivision, land use and
     environmental matters, (ii) all special permits, variances and certificates
     of occupancy, if any, issued by the New York City Planning Commission, the
     New York City Board of Estimate, the New York City Council, the New York
     City Landmarks Preservation Commission, the New York City Board of
     Standards and Appeals, the New York City Building Department and the New
     York City Fire Department, and (iii) other similar restrictions.

         3.5 No Legal Bar. The execution, delivery and performance of the Loan
Documents to which the Borrower is a party, the borrowings hereunder and the use
of the proceeds thereof will not violate any Requirement of Law or material
Contractual Obligation of the Borrower and will not result in, or require, the
creation or imposition of any Lien on any


                                      -33-
<PAGE>   39

of its or their respective properties or revenues pursuant to any such
Requirement of Law or material Contractual Obligation.

         3.6 No Material Litigation. Except as set forth on Schedule 3.6, no
litigation, investigation or proceeding of or before any arbitrator or
Governmental Authority is pending or, to the knowledge of the Borrower,
threatened by or against the Borrower or against any Property or any of its
other properties or revenues (a) with respect to any of the Loan Documents or
any of the transactions contemplated hereby or thereby, or (b) which could
reasonably be expected to have a Material Adverse Effect. All litigation, claims
and proceedings relating to a transaction proposed in 1995 by a group of Persons
organized by Samuel Zell for the refinancing of the mortgage loan made by RCPI
to RCP Associates and Rockefeller Center Properties (including without
limitation the actions captioned Zell/Merrill Lynch Real Estate Opportunity
Partners Limited Partnership III v. Rockefeller Center Properties, Inc., 96 Civ.
1445, United States District Court, Southern District of New York, and
Rockefeller Center Properties, Inc. v. Zell/Merrill Lynch Real Estate
Opportunity Partners Limited Partnership III and Equity Office Holdings, L.L.C.,
Index No. 106176/96, Supreme Court for the State of New York, New York County)
have been fully resolved and settled, all proceedings related thereto have been
dismissed with prejudice, any amounts required to be paid by the Borrower in
connection with any such settlements have been paid in full, and there are no
further obligations binding upon the Borrower in connection therewith.

         3.7 No Default. The Borrower is not in default under or with respect to
any of its Contractual Obligations in any respect which could reasonably be
expected to have a Material Adverse Effect. No Default or Event of Default has
occurred and is continuing.

         3.8  Ownership of Property; Condition of Title; Leases Major Space
              Leases and Major Retail Leases; Liens; Other Agreements.

          (a) The Borrower has good and marketable fee or leasehold title to
     each Property as set forth on Schedule 1.1(a); and the Borrower owns each
     Property free and clear of all Liens, except those Liens described on
     Schedule 3.8(a) hereof (the "Permitted Encumbrances"). The Properties
     constitute all of the real property owned, leased or operated by the
     Borrower as of the Closing Date. Schedule 1.1(a) accurately sets forth as
     to each Property the nature of the Borrower's interest therein. As of the
     date of the Rent Roll, none of the Properties is subject to any leases
     other than the Leases described in the Rent Roll. No Person has any
     possessory interest in any Property or right to occupy the same except

     Telecommunications Agreement.

          (b) The Rent Roll contains a complete list of all Leases in effect
     with respect to the Properties as of the date thereof and the information
     disclosed therein is true, accurate and complete in all material respects
     as of such date.

          (c) Except as noted on Schedule 3.8(c) the Borrower has not received
     any written notice from any tenant claiming that the Borrower is in default
     under any of the Scheduled Leases.

                                      -34-
<PAGE>   40

          (d) Schedule 3.8(d) annexed hereto is a summary of all contracts
     affecting the Properties to which Borrower is a party (other than Leases,
     Loan Documents, the Existing Loan Documents and the Property Management
     Agreement) which require payments by the Borrower in excess of $250,000 per
     annum, including without limitation, management, service and supply
     agreements, all as in effect on the date of this Agreement (herein
     collectively referred to as the "Material Service Contracts"), setting
     forth, with respect to each of the Material Service Contracts, (i) the
     names of the parties thereto, (ii) the service provided thereunder or the
     subject matter thereof, (iii) the monthly payment or other rate of payment
     payable thereunder as of the date of this Agreement and (iv) the
     termination rights of the Borrower, if any. The copies of the Material
     Service Contracts which were heretofore furnished by the Borrower to the

     of this Agreement no amounts are delinquent (under customary trade terms)
     under any Material Service Contract.

          (e) Except as set forth in Schedule 3.8(e) annexed hereto, as of the
     date of this Agreement there is no real property tax assessment pending or
     affecting any Property.

          (f) To Borrower's knowledge, the Borrower has all governmental
     permits, licenses and approvals to occupy each Property as it is occupied
     as of the date hereof, including, but not limited to, the Certificate of
     Occupancy and such governmental permits, licenses and approvals for each
     Property or the operation thereof are in full force and effect.

          (g) The Condominium Regime is in full force and effect, the
     condominium declaration therefor has been recorded in the Office of the
     Register of New York County, and has not been amended, supplemented or
     modified except as shown on Schedule 3.8(g). No assessment or unit charge
     now delinquent thereunder by Borrower remains unpaid. Borrower has not
     received any written notice of default from the Board of Managers under the
     Condominium Regime.

          (h) The Ground Leases are in full force and effect and have not been
     amended, modified or supplemented in any way. Except as noted on Schedule
     3.8(h), Borrower has no knowledge of any material default of Borrower under
     the Ground Leases.

          (i) Except as shown on Schedule 3.8(i), there are no Tenant
     Improvement Obligations under any Leases in effect on the Closing Date
     which have not been fully performed and paid for.

          (k) The Property Management Agreement is in full force and effect and
     has not been amended, modified or supplemented. To Borrower's knowledge,

                                      -35-
<PAGE>   41

     conditions that, with the passage of time or the giving of notice, or both,
     would constitute defaults thereunder. Borrower has not received any written
     notice from the Property Manager claiming that Borrower is in default under
     the Property Management Agreement.


          (l) The Expense Sharing Agreement is in full force and effect and has
     not been amended, modified or supplemented. To Borrower's knowledge, there
     are no defaults under the Expense Sharing Agreement by either party and
     there are no conditions that, with the passage of time or the giving of
     notice, or both, would constitute defaults thereunder. Borrower has not
     received any written notice from any other party thereto claiming that
     Borrower is in default under the Expense Sharing Agreement.

          (m) Attached hereto as Schedule 3.8(m) is a true and complete schedule
     of all brokerage agreements requiring payment of an amount in excess of
     $100,000 to which the Borrower is a party as of the Closing Date.

         3.9 Intellectual Property. The Borrower owns, or is licensed to use,
all trademarks, tradenames, copyrights, technology, know-how and processes
necessary for the conduct of its business as currently conducted except for
those the failure to own or license which could not reasonably be expected to
have a Material Adverse Effect (the "Intellectual Property"). No claim has been
asserted and is pending by any Person challenging or questioning the use by the
Borrower of any such Intellectual Property or the validity or effectiveness of
any such Intellectual Property. The use of such Intellectual Property by the
Borrower does not infringe on the rights of any Person, except for such claims
and infringements that, in the aggregate, could not reasonably be expected to
have a Material Adverse Effect.

         3.10 Taxes. The Borrower has filed or caused to be filed all tax
returns which, to the knowledge of the Borrower, are required to be filed and
has paid all taxes shown to be due and payable by the Borrower on said returns
or on any assessments made against it or any of its property and all other
taxes, fees or other charges imposed on it or any of its property by any
Governmental Authority (other than any the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with
respect to which reserves in conformity with GAAP have been provided on the
books of the Borrower). No tax Lien has been filed, and, to the knowledge of the
Borrower, no claim is being asserted, with respect to any such tax, fee or other
charge.

         3.11 Federal Regulations. No part of the proceeds of any Loans will be
used for "purchasing" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U of the Board of
Governors of the Federal Reserve System as now and from time to time hereafter
in effect, or for any purpose which violates, or which would be inconsistent
with, the provisions of the regulations of such Board of Governors.

         3.12 ERISA. There is no "accumulated funding deficiency" (within the
meaning of Section 412 of the Code or Section 302 of ERISA), whether or not
waived, in


                                      -36-
<PAGE>   42

respect of any Plan as of the last day of the most recent fiscal year of such
Plan ended prior to the date hereof. No Reportable Event has occurred during the
five year period prior to the date on which this representation is made or
deemed made with respect to any Plan which would have a Material Adverse Effect.
Each Plan has complied in all material respects with the applicable provisions
of ERISA and the Code. No termination of a Single Employer Plan has occurred
which has resulted in the imposition of a Lien in favor of the PBGC or a Plan
has arisen. The present value of all accrued benefits under each Single Employer
Plan (based on those assumptions used to fund such Plans) did not, as of the
last annual valuation date prior to the date on which this representation is
made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits. Neither the Borrower nor any Commonly Controlled Entity
has had a complete or partial withdrawal from any Multiemployer Plan, and
neither the Borrower nor any Commonly Controlled Entity would become subject to
any liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made. No such Multiemployer Plan is in Reorganization or Insolvent. As of
the Closing Date, neither the Borrower nor any Commonly Controlled Entity has
any liability for post retirement benefits to be provided to their current and
former employees under Plans which are employee welfare benefit plans (as
defined in Section 3(1) of ERISA).

         3.13 Investment Company Act; Other Regulations. The Borrower is not an
"investment company", or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended. The
Borrower is not subject to regulation under any Federal or State statute or
regulation (other than Regulation X of the Board of Governors of the Federal
Reserve System) which limits its ability to incur Indebtedness.

         3.14 Subsidiaries. Schedule 3.14 sets forth the name of each direct or
indirect Subsidiary of the Borrower, its form of organization, its jurisdiction
of organization, the total number of issued and outstanding shares or other
interests of Capital Stock thereof, the classes and number of issued and
outstanding shares or other interests of Capital Stock of each such class, the
name of each holder of Capital Stock thereof and the number of shares or other
interests of such Capital Stock held by each such holder and the percentage of
all outstanding shares or other interests of such class of Capital Stock held by
such holders. None of the Subsidiaries of the Borrower owns any material
property or engages in any operations except as set forth on Schedule 3.14.

         3.15 Accuracy and Completeness of Information. (a) All factual
information, reports and other papers and data with respect to the Borrower and
the Properties (other than projections) furnished, and all factual statements
and representations made, to the Agent or the Lenders by the Borrower, or on
behalf of the Borrower, were, at the time the same were so furnished or made,
when taken together with all such other factual information, reports and other
papers and data previously so furnished and all such other factual statements
and representations previously so made, complete and correct in all material
respects, to the extent necessary to give the Agent and the Lenders true and
accurate knowledge of the subject matter thereof in all material respects, and
did not, as of the date so furnished or made, contain


                                      -37-
<PAGE>   43

any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements contained therein not misleading in
light of the circumstances in which the same were made.

          (b) No fact has occurred and is known to the Borrower which has or in
     the future is reasonably likely (so far as the Borrower can reasonably
     foresee) to have a Material Adverse Effect which has not been set forth in
     the financial statements referred to in Section 3.1 or in such information,
     reports, papers and data or otherwise disclosed to the Agent or the Lenders
     prior to the Closing Date.

         3.16 Labor Relations. To Borrower's knowledge, there is (a) no unfair
labor practice compliant pending or threatened against the Borrower before the
National Labor Relations Board which could reasonably be expected to have a
Material Adverse Effect and no grievance or arbitration proceeding arising out
of or under a collective bargaining agreement is so pending or threatened; (b)
no strike, labor dispute, slowdown or stoppage pending or threatened against the
Borrower; and (c) no union representation question existing with respect to the
employees of the Borrower and no union organizing activities are taking place
with respect to any thereof.

         3.17 Insurance. The Borrower has, with respect to its properties and
business, insurance covering the risks, in the amounts, with the deductible or
other retention amounts, and with the carriers, disclosed on the insurance
certificates or other evidence of insurance delivered pursuant to Section
4.1(q), which insurance meets the requirements of Section 5.5 hereof as of the
Closing Date.

         3.18 Solvency. On the Closing Date, after giving effect to the
borrowing of Loans in an aggregate principal amount of $47,000,000 (i) the
amount of the "present fair saleable value" of the assets of the Borrower will,
as of such date, exceed the amount of all "liabilities of the Borrower,
contingent or otherwise", as of such date, as such quoted terms are determined
in accordance with applicable federal and state laws governing determinations of
the insolvency of debtors, (ii) the present fair saleable value of the assets of
the Borrower will, as of such date, be greater than the amount that will be
required to pay the liabilities of the Borrower on its debts as such debts
become absolute and matured, (iii) the Borrower will not have, as of such date,
an unreasonably small amount of capital with which to conduct its business, and
(iv) the Borrower will be able to pay its debts as they mature. For purposes of
this Section 3.18, "debt" means "liability on a claim", "claim" means any (x)
right to payment, whether or not such a right is reduced to judgment,
liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed,
undisputed, legal, equitable, secured or unsecured, and (y) right to an
equitable remedy for breach of performance if such breach gives rise to a right
to payment, whether or not such right to an equitable remedy is reduced to
judgment, fixed, contingent, matured or unmatured, disputed, undisputed, secured
or unsecured.

         3.19 Purpose of Loans. The proceeds of the Loans shall be used by the
Borrower to fund budgeted tenant work allowances and leasing commissions, to
fund capital improvements to the Properties, to fund scheduled amortization
payments of the Existing Loans under the Existing Senior Credit Agreement, and
for other general working capital


                                      -38-
<PAGE>   44

purposes of the Borrower. None of the proceeds of the Loans shall be used to pay
any amounts in connection with any settlement, decree or judgment entered in
connection with any investigation, litigation or proceeding.

         3.20 Environmental Matters. Except as set forth on Schedule 3.20:

          (a) To the Borrower's knowledge and except as disclosed in any
     environmental report delivered to the Agent by or on behalf of the Borrower
     on or prior to the Closing Date, the Properties do not contain any
     Materials of Environmental Concern in amounts or concentrations which (i)
     constitute or constituted a violation of, or (ii) could reasonably be
     expected to give rise to liability under, any Environmental Law except in
     either case insofar as such violation or liability, or any aggregation
     thereof, is not reasonably likely to result in the payment of a Material
     Environmental Amount.

          (b) To the Borrower's knowledge and except as disclosed in any
     environmental report delivered to the Agent by or on behalf of the Borrower
     on or prior to the Closing Date, the Properties and all operations at the
     Properties are in compliance, and have since July 17, 1996 been in
     compliance, in all material respects with all applicable Environmental
     Laws, and there is no contamination at, under or about the Properties in
     violation of any Environmental Law with respect to the Properties or the
     business operated by the Borrower (the "Business") which could materially
     interfere with the continued operation of the Properties or materially
     impair the fair saleable value thereof.

          (c) The Borrower has not received any notice of violation, alleged
     violation, non-compliance, liability or potential liability regarding
     environmental matters or compliance with Environmental Laws with regard to
     any of the Properties or the Business, nor does the Borrower have knowledge
     or reason to believe that any such notice will be received or is being
     threatened except insofar as such notice or threatened notice, or any
     aggregation thereof, does not involve a matter or matters that is or are
     reasonably likely to result in the payment of a Material Environmental
     Amount.

          (d) To the Borrower's knowledge, Materials of Environmental Concern
     have not been transported or disposed of from the Properties in violation
     of, or in a manner or to a location which could reasonably be expected to
     give rise to liability under, any Environmental Law, nor have any Materials
     of Environmental Concern been generated, treated, stored or disposed of at,
     on or under any of the Properties in violation of, or in a manner that
     could reasonably be expected to give rise to liability under, any
     applicable Environmental Law except insofar as any such violation or
     liability referred to in this paragraph, or any aggregation thereof, is not
     reasonably likely to result in the payment of a Material Environmental
     Amount.

          (e) No judicial proceeding or governmental or administrative action is
     pending or, to the knowledge of the Borrower, threatened, under any
     Environmental Law to which the Borrower is or is threatened to be named as
     a party with respect to


                                      -39-
<PAGE>   45

     the Properties or the Business, nor are there any consent decrees or other
     decrees, consent orders, administrative orders or other orders, or other
     administrative or judicial requirements outstanding under any Environmental
     Law with respect to the Properties or the Business except insofar as such
     proceeding, action, decree, order or other requirement, or any aggregation
     thereof, is not reasonably likely to result in the payment of a Material
     Environmental Amount.

          (f) To the Borrower's knowledge, there has been no release or threat
     of release of Materials of Environmental Concern at or from the Properties,
     or arising from or related to the operations of the Borrower in connection
     with the Properties or otherwise in connection with the Business, in
     violation of or in amounts or in a manner that could reasonably give rise
     to liability under Environmental Laws except insofar as any such violation
     or liability referred to in this paragraph, or any aggregation thereof, is
     not reasonably likely to result in the payment of a Material Environmental
     Amount.

         3.21 Obligation to Convey. As of the Closing Date, there is no contract
or other obligation providing for or requiring the Borrower to convey (other
than lease) any interest in any of the Properties to any Person.

         3.22 Certain Existing Indebtedness. (a) As of the Closing Date, (i) the
aggregate outstanding principal amount of the 14% Debentures is $75,000,000 and
(ii) the aggregate accreted amount with respect to all Zeros outstanding is
approximately $496,116,000. During the period from May 16, 1997 to and including
April 12, 1999, neither the 14% Debentures, nor any interest therein, has been
sold, assigned or otherwise transferred or amended (other than the amendment to
the 14% Debenture Purchase Agreement entered into as of the date hereof),
supplemented or otherwise modified. During the period from May 16, 1997 to and
including April 12, 1999, the Zeros Indenture has not been amended, supplemented
or otherwise modified.

          (b) After giving effect to the execution and delivery of the Loan
     Documents, no provision of the Zeros or the Zeros Indenture requires that
     the Zeros shall be prepaid, redeemed, repurchased or defeased with any
     portion of any proceeds of any sale, lease, assignment, transfer, pledge,
     exchange or other disposition or hypothecation of any property of the
     Borrower (including, without limitation, any proceeds received upon any
     destruction, casualty or condemnation with respect to any such property).

         3.23 Year 2000. The Borrower has (i) initiated a review and assessment
of all areas within its and each of its Subsidiaries' business and operations
that could be adversely affected by the Year 2000 Problem, (ii) developed a plan
and timeline for addressing the Year 2000 Problem on a timely basis, and (iii)
to date, implemented that plan in accordance with that timetable. Based on the
foregoing, the Borrower believes that all computer applications that are
material to its or any of its Subsidiaries' business and operations are
reasonably expected on a timely basis to be able to perform properly
date-sensitive functions for all dates before and after January 1, 2000 in all
material respects ("Year 2000 Compliant"), except to the extent that a failure
to do so would not reasonably be expected to have a Material Adverse Effect.

precedent:

          (a) Representations and Warranties. Each of the representations and
     warranties made by the Borrower in or pursuant to the Loan Documents shall

     the provisions of this Agreement and the other Loan Documents.

          (d) Additional Matters. All corporate and other proceedings, and all
     documents, instruments and other legal matters in connection with the

pay, discharge or satisfy such obligations would not result in a Material
Adverse Effect.

          (b) Without limiting the generality of the foregoing, (i) pay all
     taxes (including any component of maintenance charges comprised of taxes),

permitted pursuant to Section 6.4; comply with all Contractual Obligations and

         5.5 Maintenance of Property; Insurance. (a) Keep all property useful
and necessary in its business in good working order and condition.

          (b) The Borrower will keep each Property insured as follows:

          (i) "All Risk" property insurance, including sprinkler leakage in an
     amount sufficient to prevent the Borrower from becoming a co-insurer of any
     loss under the terms of the policy but in no event less than the then full
     replacement value of such Property;

          (ii) rental value insurance in an amount equal to not less than one
     year's gross rent from such Property;

          (iii) steam boiler and machinery breakdown direct damage insurance and
     third-party liability coverage (if not covered under the comprehensive
     general liability policy), with full comprehensive coverage on a repair and
     replacement cost basis, for all boilers and machinery which form a part of
     such Property, including rental value insurance in connection therewith in
     accordance with subsection (ii) of this Section 5.5(b) above;

          (iv) comprehensive general liability insurance with respect to all the

     value basis insuring against such risks (including, without limitation,
     fire and extended coverage, collapse of such Property) as the Agent may
     request, in form and substance acceptable to the Agent;

          (vi) a policy or policies of workers' compensation insurance as
     required by workers' compensation insurance laws subject to the statutory
     limits of the State of New York in respect of any work or other operations
     on, about or in connection with all the Properties and covering all
     employees of the Borrower and employer's liability insurance coverage of
     not less than $5,000,000; and

          (vii) such other insurance with respect to such Property as the Agent

                                      -48-
<PAGE>   54

          (c) All policies of insurance required under this Section 5.5 shall be
     issued by companies having a claims paying ability determined by A. M. Best
     Company of A or better and which are licensed to do business in the State
     of New York or with such other companies satisfactory to the Agent. The
     Agent shall be furnished with a duplicate original of each policy required
     to be provided by the Borrower hereunder, which policy shall provide that
     no cancellation, material change or reduction thereof shall be effective
     until at least ten (10) Business Days after receipt by the Agent of written
     notice thereof. At least ten (10) Business Days prior to expiration of any
     policy required to be provided by the Borrower hereunder, the Borrower
     shall furnish the Agent (without notice or demand by the Agent) with a
     duplicate original of such renewal policy replacing the policy so expiring;
     provided, however, if such renewal policy is not yet available, the
     Borrower shall provide the Agent with an insurance certificate or
     certificates thereof executed by the insurer or its authorized agent
     evidencing the insurance maintained under such policy which shall be
     acceptable to the Agent on an interim basis until the duplicate original
     thereof is available. The Borrower shall furnish the Agent receipts for the
     payment of premiums on such insurance policies or other evidence of such
     payment satisfactory to the Agent. In the event that the Borrower does not
     deposit with the Agent a new duplicate original policy of insurance with
     evidence of payment of premiums thereon at least ten (10) Business Days
     prior to the expiration of any expiring policy, then the Agent may, but
     shall not be obligated to, procure such insurance and pay the premiums
     therefor, and the Borrower agrees to repay to the Agent the premiums
     thereon promptly on demand, together with interest thereon at the rate per
     annum which would be applicable to Base Rate Loans under Section 2.7(c) and
     the same shall be part of the Obligations.

          (d) The Borrower may effect coverage under this Section 5.5 under a
     blanket insurance policy satisfactory to the Agent, provided that (i) any
     such policy of blanket insurance shall specify therein, or the insurer
     under such policy shall certify to the Agent, (A) the maximum amount of the
     total insurance afforded by the blanket policy allocated to such Property,
     and (B) any sublimits in such blanket policy applicable to such Property,
     which amounts shall not be less than the limits required pursuant to the
     provisions of this Section 5.5; (ii) any such policy of blanket insurance
     shall comply in all respects with the other provisions of this Section 5.5;
     and (iii) the protection afforded under any policy of blanket insurance
     hereunder shall be no less than that which would have been afforded under a
     separate policy or policies relating only to such Property.

          (e) The Borrower shall not take out separate insurance concurrent in
     form or contributing in the event of loss with the insurance required under
     this Section 5.5 unless (i) the policies are submitted to the Agent for its
     approval; and (ii) the insurers thereunder and the terms thereof are not
     unreasonably disapproved of by the Agent within 10 Business Days of such
     submission. The Borrower shall notify the Agent thirty (30) days before any
     such separate insurance is taken out and shall furnish the Agent with
     duplicate originals of the policy or policies or certificate or
     certificates of insurance executed by the insurer or its authorized agent
     with respect thereto, in the


                                      -49-
<PAGE>   55

     same manner as provided in subsection (c) of this Section 5.5 with respect
     to insurance required to be maintained hereunder.

          (f) For purposes of this Section, the term "full replacement value"
     shall mean the actual cost of replacing the property in question, exclusive
     of the cost of excavations, foundations and footings, as determined from
     time to time (but not less often than once every calendar year) by the
     insurance company or companies holding such insurance or by an appraiser,
     engineer, architect or contractor proposed by the Borrower and approved by
     said company or companies and the Agent.

          (g) No approval by the Agent of any insurer shall be construed to be a
     representation, certification or warranty of its solvency and no approval
     by the Agent as to the amount, type and/or form of any insurance shall be
     construed to be a representation, certification or warranty of its
     sufficiency.

         5.6 Damage, Destruction, Condemnation. (a) In the event of any damage
to or loss or destruction of any Property, the Borrower shall (i) promptly
notify the Agent of such event and take such steps as shall be necessary to
preserve any undamaged portion of such Property and (ii) if no Event of Default
has occurred and is continuing, at the Borrower's election (subject to the
requirements of clause (b) of this Section 5.6), or if an Event of Default has
occurred and is continuing, at the Agent's election, either (x) commence and
diligently pursue to completion the restoration, replacement and rebuilding of
such Property as nearly as possible to its value, condition and character
immediately prior to such damage, loss or destruction and in accordance with
plans and specifications reasonably approved by the Agent, and apply the excess,
if any, of the Net Proceeds of any insurance award over the amount required to
be applied to the Existing Loans pursuant to Section 5.6(a) of the Existing
Senior Credit Agreement thereto, or (y) apply the excess, if any, of the Net
Proceeds of any insurance award over the amount required to be applied to the
Existing Loans pursuant to Section 5.6(a) of the Existing Senior Credit
Agreement to prepay the Loans (without premium or penalty).

          (b) In the event that any portion of any Property is so damaged,
     destroyed or lost, and such damage, destruction or loss is covered, in
     whole or in part, by insurance described in Section 5.5, then, (i) if no
     Event of Default has occurred and is continuing and the amount of Net
     Proceeds received (or reasonably anticipated by the Borrower to be
     received) in connection with such damage, destruction or loss is less than
     $50,000,000, then the Borrower may retain such Net Proceeds and, at the
     Borrower's option, apply such Net Proceeds to the restoration, replacement
     or rebuilding, in whole or in part, of the portion of such Property so
     damaged, destroyed or lost or to the prepayment of the Existing Loans and,
     to the extent that the Existing Loans have been paid in full, the Loans,
     provided, however, that the Borrower shall be required to apply the excess,
     if any, of such Net Proceeds over the amount required to be applied to the
     Existing Loans pursuant to Section 5.6(b) of the Existing Senior Credit
     Agreement to the prepayment of the Loans (x) if the Borrower shall have
     failed to commence the restoration, replacement or rebuilding, in whole or
     in part, of the portion of such Property so damaged, destroyed or lost
     within six months following the receipt of such Net Proceeds or (y) if the
     Borrower shall cease to be diligently continuing such


                                      -50-
<PAGE>   56

     restoration, replacement or rebuilding, in the case of each of (x) and (y),
     subject to force majeure; or (ii) if no Event of Default has occurred and
     is continuing and the amount of Net Proceeds received (or reasonably
     anticipated by the Borrower to be received) in connection with such damage,
     destruction or loss is $50,000,000 or greater, then the Borrower shall
     cause the excess, if any, of such Net Proceeds over the amount required to
     be applied to the Existing Loans pursuant to Section 5.6(b) of the Existing
     Senior Credit Agreement to be deposited in a segregated account at a bank
     (which need not be a Lender) selected by the Borrower, and the Borrower
     hereby covenants and agrees that the excess, if any, of such Net Proceeds
     over the amount required to be applied to the Existing Loans pursuant to
     Section 5.6(b) of the Existing Senior Credit Agreement shall be withdrawn
     from such segregated account and applied solely for the purpose of, and in
     the amounts necessary to, make required payments in connection with the
     restoration, replacement or rebuilding, in whole or in part, of the portion
     of such Property so damaged, destroyed or lost or to the prepayment of the
     Loans; provided, however, that the Borrower shall be required to apply the
     excess, if any, of such Net Proceeds over the amount required to be applied
     to the Existing Loans pursuant to Section 5.6(b) of the Existing Senior
     Credit Agreement to the prepayment of the Loans (x) if the Borrower shall
     have failed to commence the restoration, replacement or rebuilding, in
     whole or in part, of the portion of such Property so damaged, destroyed or
     lost within six months following the receipt of such Net Proceeds or (y) if
     the Borrower shall cease to be diligently continuing such restoration,
     replacement or rebuilding, in the case of each of (x) and (y), subject to
     force majeure.

          (c) The Borrower, promptly upon obtaining knowledge of any pending or
     threatened institution of any proceedings for the condemnation of any
     Property, or any part or interest therein, or of any right of eminent
     domain, or of any other proceedings arising out of injury or damage to or
     decrease in the value of any Property (including a change in grade of any
     street), or any part thereof or interest therein, will notify the Agent of
     the threat or pendency thereof. The Borrower shall, at its expense,
     diligently prosecute any such proceedings. In the event of any condemnation
     of any Property or any part or interest therein or any similar event with
     respect thereto, if no Event of Default has occurred and is continuing, at
     the Borrower's option (subject to the requirements of clause (d) of this
     Section 5.6), and if an Event of Default has occurred and is continuing, at
     the Agent's option, the Borrower shall either (x) commence and diligently
     pursue to completion the replacement of such Property as nearly as possible
     to its value, condition and character immediately prior to such
     condemnation or similar event in accordance with plans and specifications
     reasonably approved by the Agent, and apply the excess, if any, of the Net
     Proceeds of any award over the amount required to be applied to the
     Existing Loans pursuant to Section 5.6(c) of the Existing Senior Credit
     Agreement thereto, or (y) apply the excess, if any, of the Net Proceeds of
     any award received by the Borrower over the amount required to be applied
     to the Existing Loans pursuant to Section 5.6(c) of the Existing Senior
     Credit Agreement to prepay the Loans (without premium or penalty).

          (d) In the event of any condemnation of any Property or any part or
     interest therein or any similar event with respect thereto, then, (i) if no
     Event of Default has


                                      -51-
<PAGE>   57

     occurred and is continuing and the amount of Net Proceeds received (or
     reasonably anticipated by the Borrower to be received) in connection with
     such condemnation or similar event is less than $50,000,000, then the
     Borrower may retain such Net Proceeds and, at the Borrower's option, apply
     such Net Proceeds to the replacement, in whole or in part, of such Property
     or such part thereof so condemned or to the prepayment of the Existing
     Loans and, to the extent the Existing Loans have been paid in full, the
     Loans, provided, however, that the Borrower shall be required to apply the
     excess, if any, of such Net Proceeds over the amount required to be applied
     to the Existing Loans pursuant to Section 5.6(d) of the Existing Senior
     Credit Agreement to the prepayment of the Loans (x) if the Borrower shall
     have failed to commence the replacement of such Property or such part

                  SECTION 8. THE AGENT

                  8.1 Appointment. Each Lender hereby irrevocably designates and
appoints the Agent as the agent of such Lender under this Agreement and the
other Loan Documents, and each such Lender irrevocably authorizes the Agent, in
such capacity, to take such action on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers and perform
such duties as are expressly delegated to the Agent by the terms of this
Agreement and the other Loan Documents, together with such other powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
elsewhere in this Agreement, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the Agent.

                  8.2 Delegation of Duties. The Agent may execute any of its
duties under this Agreement and the other Loan Documents by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The


                                      -65-
<PAGE>   71
Agent shall not be responsible for the negligence or misconduct of any agents or
attorneys in-fact selected by it with reasonable care.

                  8.3 Exculpatory Provisions. Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be
(i) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Agreement or any other Loan Document
(except for its or such Person's own gross negligence or willful misconduct) or
(ii) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by the Borrower or any officer
thereof contained in this Agreement or any other Loan Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in connection with, this Agreement or any
other Loan Document or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan Document or
for any failure of the Borrower to perform its obligations hereunder or
thereunder. The Agent shall not be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of the Borrower.

                  8.4 Reliance by Agent. The Agent shall be entitled to rely,
and shall be fully protected in relying, upon any Note, writing, resolution,
notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy,
telex or teletype message, statement, order or other document or conversation
believed by it to be genuine and correct and to have been signed, sent or made
by the proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to the Borrower or any other Loan
Party), independent accountants and other experts selected by the Agent. The
Agent may deem and treat the payee of any Note as the owner thereof for all
purposes unless a written notice of assignment, negotiation or transfer thereof
shall have been filed with the Agent. The Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Required Lenders as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement and the other Loan Documents in accordance with a
request of the Required Lenders, and such request and any action taken or
failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Loans.

                  8.5 Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Agent has received notice from a Lender or the Borrower
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". In the event that the Agent
receives such a notice, the Agent shall give notice thereof to the Lenders. The
Agent shall take such action with respect to such Default or Event of Default as
shall be reasonably directed by the Required Lenders; provided that unless and
until the Agent shall have received such directions, the Agent may (but shall
not be obligated to) take such action,


                                      -66-
<PAGE>   72
or refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interests of the Lenders.

                  8.6 Non-Reliance on Agent and Other Lenders. Each Lender
expressly acknowledges that neither the Agent nor any of its officers,
directors, employees, agents, attorneys-in-fact or Affiliates has made any
representations or warranties to it and that no act by the Agent hereinafter
taken, including any review of the affairs of the Borrower or any other Loan
Party, shall be deemed to constitute any representation or warranty by the Agent
to any Lender. Each Lender represents to the Agent that it has, independently
and without reliance upon the Agent or any other Lender, and based on such
documents and information as it has deemed appropriate, made its own appraisal
of and investigation into the business, operations, property, financial and
other condition and creditworthiness of the Borrower and the other Loan Parties
and made its own decision to make its Loans hereunder and enter into this
Agreement. Each Lender also represents that it will, independently and without
reliance upon the Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigation as
it deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Borrower. Except for
notices, reports and other documents expressly required to be furnished to the
Lenders by the Agent hereunder or under the other Loan Documents, the Agent
shall not have any duty or responsibility to provide any Lender with any credit
or other information concerning the business, operations, property, condition
(financial or otherwise), prospects or creditworthiness of the Borrower or any
other Loan Party which may come into the possession of the Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

                  8.7 Indemnification. The Lenders agree to indemnify the Agent
and the Arranger in their respective capacities as such (to the extent not
reimbursed by the Borrower and without limiting the obligation of the Borrower
to do so), ratably according to their respective Credit Exposure Percentages in
effect on the date on which indemnification is sought, from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind whatsoever which may at any
time (including, without limitation, at any time following the payment of the
Loans) be imposed on, incurred by or asserted against the Agent or the Arranger
in any way relating to or arising out of, the Commitments, this Agreement, any
of the other Loan Documents or any documents contemplated by or referred to
herein or therein or the transactions contemplated hereby or thereby or any
action taken or omitted by the Agent or the Arranger under or in connection with
any of the foregoing; provided that no Lender shall be liable for the payment of
any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting solely
from the Agent's or the Arranger's gross negligence or willful misconduct. The
agreements in this Section shall survive the payment of the Loans and all other
amounts payable hereunder.

                  8.8 Agent in Its Individual Capacity. The Agent and its
Affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the Borrower and the other Loan Parties as though the
Agent were not the Agent hereunder and


                                      -67-
<PAGE>   73
under the other Loan Documents. With respect to the Loans made by it, the Agent
shall have the same rights and powers under this Agreement and the other Loan
Documents as any Lender and may exercise the same as though it were not the
Agent, and the terms "Lender" and "Lenders" shall include the Agent in its
individual capacity.

                  8.9 Successor Agent. The Agent may resign as Agent upon
10 days' notice to the Lenders. If the Agent shall resign as Agent under this
Agreement and the other Loan Documents, then the Required Lenders shall appoint
from among the Lenders a successor agent for the Lenders, which successor agent
shall be approved by the Borrower, whereupon such successor agent shall succeed
to the rights, powers and duties of the Agent, and the term "Agent" shall mean
such successor agent effective upon such appointment and approval, and the
former Agent's rights, powers and duties as Agent shall be terminated, without
any other or further act or deed on the part of such former Agent or any of the
parties to this Agreement or any holders of the Loans. After any retiring
Agent's resignation as Agent, the provisions of this Section 8 shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent under this Agreement and the other Loan Documents.

                  8.10 Dealings with Agent. Except as otherwise expressly
provided herein, in connection with any matter consented to, approved or waived
by the Lenders or to be consented to, approved or waived by the Lenders, as
between the Borrower, on the one hand, and the Lenders and the Agent, on the
other hand, the Borrower shall be entitled to rely upon the Agent's approval or
consent.

                  8.11 Co-Agent. The Co-Agent shall have no rights, powers,
duties or responsibilities (other than as a Lender) hereunder or under any other
Loan Document. To the extent that the Borrower is permitted or required to deal
with or rely upon the Agent under any of the Loan Documents, the Borrower shall
be permitted or required to deal with or rely solely upon NationsBank, N.A., as
agent, or any successor agent appointed in accordance with Section 8.9 hereof.

                  SECTION 9. MISCELLANEOUS

                  9.1 Amendments and Waivers. Neither this Agreement nor any
other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this
Section 9.1. The Required Lenders may, or, with the written consent of the
Required Lenders, the Agent may, from time to time, (a) enter into with the
Borrower written amendments, supplements or modifications hereto and to the
other Loan Documents for the purpose of adding any provisions to this Agreement
or the other Loan Documents or changing in any manner the rights of the Lenders
or of the Borrower hereunder or thereunder or (b) waive, on such terms and
conditions as the Required Lenders or the Agent, as the case may be, may specify
in such instrument, any of the requirements of this Agreement or the other Loan
Documents or any Default or Event of Default and its consequences; provided,
however, that no such waiver and no such amendment, supplement or modification
shall (i) reduce the amount or extend the scheduled date of maturity of any Loan
or of any installment thereof, or reduce the stated rate of any interest or fee
payable hereunder or extend the scheduled date of any payment thereof or
increase the aggregate amount or


                                      -68-
<PAGE>   74
extend the expiration date of any Lender's Commitment, in each case without the
consent of each Lender affected thereby, or (ii) amend, modify or waive any
provision of this Section 9.1 or reduce the percentage specified in the
definition of Required Lenders or Majority Lenders, or consent to the assignment
or transfer by the Borrower of any of its rights and obligations under this
Agreement and the other Loan Documents or release any collateral for the
Obligations or any Recourse Party from its obligations under the Limited
Recourse Agreement, in each case without the written consent of all the Lenders,
or (iii) amend, modify or waive any provision of Section 8 without the written
consent of the then Agent. Any such waiver and any such amendment, supplement or
modification shall apply equally to each of the Lenders and shall be binding
upon the Borrower, the Lenders, the Agent and all future holders of the Loans.
In the case of any waiver, the Borrower, the Lenders and the Agent shall be
restored to their former positions and rights hereunder and under the other Loan
Documents, and any Default or Event of Default waived shall be deemed to be
cured and not continuing; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

                  9.5 Payment of Expenses and Taxes. The Borrower agrees (a) to
pay or reimburse the Agent and the Arranger, and each Lender (but limited, with
respect to the Lenders pursuant to this Section 9.5(a), but not with respect to
the Agent or Arranger, to an aggregate amount not to exceed the lesser of (i)
$5,000 per Lender and (ii) $35,000 in the aggregate for all Lenders) for all
their out-of-pocket costs and expenses incurred in connection with the

modification to, this Agreement and the other Loan Documents and any other
documents prepared in connection herewith or therewith, and the consummation and
(except with respect to the Lenders) the administration of the transactions

including, without limitation, the fees and disbursements of counsel to each
Lender and of counsel to the Agent, (c) to pay, indemnify, and hold each Lender

all liabilities with respect to, or resulting from any delay in paying, stamp,
excise and other taxes, if any, which may be payable or determined to be payable

noncompliance with or liability under, any Environmental Law applicable to the
operations of the Borrower, any of its Subsidiaries, or any of the Properties
(all the foregoing in this clause (d), collectively, the "indemnified
liabilities"), provided, that the Borrower shall have no obligation hereunder to
the Agent, Arranger or any Lender with respect to indemnified liabilities
arising from (i) the gross negligence or willful misconduct of the Agent,
Arranger or any such Lender or (ii) legal proceedings commenced against the
Agent, Arranger or any such Lender by any security holder or creditor thereof
arising out of and based upon rights afforded any such security holder or
creditor solely in its capacity as such. The agreements in this Section shall
survive repayment of the Loans and all other amounts payable hereunder.

                  9.6 Successors and Assigns; Participations and Assignments.
(a) This Agreement shall be binding upon and inure to the benefit of the
Borrower, the Lenders, the Agent and their respective successors and assigns,
except that the Borrower may not assign or transfer any of its rights or
obligations under this Agreement without the prior written consent of each
Lender.

                  (b) Any Lender may, in the ordinary course of its commercial
         banking business and in accordance with applicable law, at any time
         sell to one or more banks or other entities ("Participants")
         participating interests in any Loan owing to such Lender, any
         Commitment of such Lender or any other interest of such Lender
         hereunder and under the other Loan Documents. In the event of any such
         sale by a Lender of a participating interest to a Participant, such
         Lender's obligations under this Agreement to the other parties to this
         Agreement shall remain unchanged, such Lender shall remain solely
         responsible for the performance thereof, such Lender shall remain the
         holder of any such Loan for all purposes under this Agreement and the
         other Loan Documents, and the Borrower and the Agent shall continue to
         deal solely and directly with such Lender in connection with such
         Lender's rights and obligations under this Agreement and the other Loan
         Documents. The Borrower agrees that if amounts outstanding under this
         Agreement are due or unpaid, or shall have been declared or shall have
         become due and payable upon the occurrence of an Event of Default, each
         Participant shall, to the maximum extent permitted by applicable law,
         be deemed to have the right of setoff in respect of its participating
         interest in amounts owing under this Agreement to the same extent as if
         the amount of its participating interest were owing directly to it as a
         Lender under this Agreement, provided that, in purchasing such
         participating interest, such Participant shall be deemed to have agreed
         to share with the Lenders the proceeds thereof as provided in Section
         9.7(a) as fully as if it were a Lender hereunder. The Borrower also
         agrees that each Participant shall be entitled to the benefits of
         Sections 2.16, 2.17 and 2.18 with respect to its participation in the
         Commitments and the Loans outstanding from time to time as if it was a
         Lender; provided that, in the case of Section 2.17, such Participant
         shall have complied with the requirements of said Section and provided,
         further, that no Participant shall be entitled to receive any greater
         amount pursuant to any such Section than the transferor Lender would
         have been entitled to receive in respect of the amount of the
         participation transferred by such transferor Lender to such Participant
         had no such transfer occurred.

                  (c) Any Lender may, in the ordinary course of its commercial
         banking business and in accordance with applicable law, at any time and
         from time to time assign to any Lender or to an additional bank or
         financial institution or entity which is an Eligible Assignee or, with
         the consent of the Agent (in its sole discretion) and the Borrower
         (which consent of the Borrower shall not be unreasonably withheld,
         delayed or conditioned; provided, that it shall not be unreasonable for
         the Borrower to withhold consent to an additional bank, financial
         institution or entity that fails to execute and deliver a certificate
         in the form of Exhibit G hereto), to an additional bank or financial
         institution or entity which is not a Lender or an Eligible Assignee
         (such assignee Lender, Eligible Assignee or other financial institution
         or entity, an "Assignee") all or any part of its rights and obligations
         under this Agreement and the other Loan


                                      -72-
<PAGE>   78
         Documents pursuant to an Assignment and Acceptance, substantially in
         the form of Exhibit E, with appropriate completions (an "Assignment and
         Acceptance"), executed by such Assignee, such assigning Lender (and, in
         the case of an Assignee that is not then a Lender, by the Agent) and
         delivered to the Agent for its acceptance and recording in the
         Register, provided, that in the case of any such assignment to an
         additional bank or financial institution, the sum of the aggregate
         principal amount of the Loans and Available Commitment being assigned
         shall be at least $5,000,000 or, if less, all of the rights and
         obligations of the assigning Lender. Upon such execution, delivery,
         acceptance and recording, from and after the effective date determined
         pursuant to such Assignment and Acceptance, (x) the Assignee thereunder
         shall be a party hereto and, to the extent provided in such Assignment
         and Acceptance, have the rights and obligations of a Lender hereunder
         with Commitments as set forth therein, and (y) the assigning Lender
         thereunder shall, to the extent provided in such Assignment and
         Acceptance, be released from its obligations under this Agreement (and,
         in the case of an Assignment and Acceptance covering all or the
         remaining portion of an assigning Lender's rights and obligations under
         this Agreement, such assigning Lender shall cease to be a party
         hereto). Notwithstanding any provision of this paragraph (c) and
         paragraph (e) of this Section, the consent of the Borrower shall not be
         required, and, unless requested by the Assignee and/or the assigning
         Lender, new Notes shall not be required to be executed and delivered by
         the Borrower, for any assignment which occurs at any time when any of
         the events described in Section 7(h) with respect to the Borrower shall
         have occurred and be continuing.

                  (d) The Agent, on behalf of the Borrower, shall maintain at
         the address of the Agent referred to in Section 9.2 a copy of each
         Assignment and Acceptance delivered to it and a register (the
         "Register") for the recordation of the names and addresses of the
         Lenders and the Commitments of, and principal amounts of the Loans
         owing to, each Lender from time to time. The entries in the Register
         shall be conclusive, in the absence of manifest error, and the
         Borrower, the Agent and the Lenders may (and, in the case of any Loan
         or other obligation hereunder not evidenced by a Note, shall) treat
         each Person whose name is recorded in the Register as the owner of a
         Loan or other obligation hereunder as the owner thereof for all
         purposes of this Agreement and the other Loan Documents,
         notwithstanding any notice to the contrary. Any assignment of any Loan
         or other obligation hereunder not evidenced by a Note shall be
         effective only upon appropriate entries with respect thereto being made
         in the Register. The Register shall be available for inspection by the
         Borrower or any Lender at any reasonable time and from time to time
         upon reasonable prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance executed
         by an assigning Lender and an Assignee (and, in the case of an Assignee
         that is not then a Lender, by the Agent) together with payment to the
         Agent of a registration and processing fee of $3,500, the Agent shall
         (i) promptly accept such Assignment and Acceptance and (ii) on the
         effective date determined pursuant thereto record the information
         contained therein in the Register and give notice of such acceptance
         and recordation to the Lenders and the Borrower.


                                      -73-
<PAGE>   79
                  (f) The Borrower authorizes each Lender to disclose to any
         Participant or Assignee (each, a "Transferee") and any prospective
         Transferee, subject to the provisions of Section 9.15, any and all
         financial information in such Lender's possession concerning the
         Borrower and its Affiliates which has been delivered to such Lender by
         or on behalf of the Borrower pursuant to this Agreement or which has
         been delivered to such Lender by or on behalf of the Borrower in
         connection with such Lender's credit evaluation of the Borrower and its
         Affiliates prior to becoming a party to this Agreement.

                  (g) For avoidance of doubt, the parties to this Agreement
         acknowledge that the provisions of this Section concerning assignments
         of Loans and Notes relate only to absolute assignments and that such
         provisions do not prohibit assignments creating security interests,
         including, without limitation, any pledge or assignment by a Lender of
         any Loan or Note to any Federal Reserve Bank in accordance with
         applicable law.

                  (h) Notwithstanding anything to the contrary set forth in this
         Section 9.6, no assignment by NationsBank or its Affiliates under
         Section 9.6(c) shall be permitted unless, immediately after giving
         effect to such assignment, the Commitment and Loans of NationsBank and
         its Affiliates shall be not less than the lesser of (i) $10,000,000 and
         (ii) 21% of the aggregate Commitments and Loans of all of the Lenders.

                  9.7 Adjustments; Set-off. (a) If any Lender (a "benefited
Lender") shall at any time receive any payment of all or part of its Loans, or
interest thereon, or receive any collateral in respect thereof (whether
voluntarily or involuntarily, by set-off, pursuant to events or proceedings of
the nature referred to in Section 7(g), or otherwise), in a greater proportion
than any such payment to or collateral received by any other Lender, if any, in
respect of such other Lender's Loans, or interest thereon, such benefited Lender
shall purchase for cash from the other Lenders a participating interest in such
portion of each such other Lender's Loan, or shall provide such other Lenders
with the benefits of any such collateral, or the proceeds thereof, as shall be
necessary to cause such benefited Lender to share the excess payment or benefits
of such collateral or proceeds ratably with each of the Lenders; provided,
however, that if all or any portion of such excess payment or benefits is
thereafter recovered from such benefited Lender, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest. The Borrower agrees that each Lender so
purchasing a portion of another Lender's Loan may exercise all rights of payment
(including, without limitation, rights of set-off) with respect to such portion
as fully as if such Lender were the direct holder of such portion.

                  (b) In addition to any rights and remedies of the Lenders
         provided by law, each Lender shall have the right, without prior notice
         to the Borrower, any such notice being expressly waived by the Borrower
         to the extent permitted by applicable law, upon any amount becoming due
         and payable by the Borrower hereunder (whether at the stated maturity,
         by acceleration or otherwise), but after compliance with any applicable
         notice provisions and after expiration of any applicable grace periods,
         to set-off and appropriate and apply against such amount any and all
         deposits (general or special, time or demand, provisional or final), in
         any currency, and any other credits, indebtedness


                                      -74-

         or claims, in any currency, in each case whether direct or indirect,
         absolute or contingent, matured or unmatured, at any time held or owing
         by such Lender or any branch or agency thereof to or for the credit or
         the account of the Borrower. Each Lender agrees promptly to notify the
         Borrower and the Agent after any such set-off and application made by
         such Lender, provided that the failure to give such notice shall not
         affect the validity of such set-off and application.

                  9.8 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts
(including by facsimile transmission of signature pages hereto), and all of said
counterparts taken together shall be deemed to constitute one and the same
instrument. A set of the copies of this Agreement signed by all the parties
shall be lodged with the Borrower and the Agent.

                  9.9 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                  9.10 Integration. This Agreement and the other Loan Documents
represent the agreement of the Borrower, the Agent and the Lenders with respect
to the subject matter hereof, and there are no promises, undertakings,
representations or warranties by the Agent or any Lender relative to subject
matter hereof not expressly set forth or referred to herein or in the other Loan
Documents.

                  9.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND

                  (b) consents that any such action or proceeding may be brought
         in such courts and waives any objection that it may now or hereafter
         have to the venue of any such action or proceeding in any such court or
         that such action or proceeding was brought in an inconvenient court and
         agrees not to plead or claim the same;

                  (c) agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially

         shall have been notified pursuant thereto;

                  (d) agrees that nothing herein shall affect the right to
         effect service of process in any other manner permitted by law or shall
         limit the right to sue in any other jurisdiction; and

                  (e) waives, to the maximum extent not prohibited by law, any
         right it may have to claim or recover in any legal action or proceeding
         referred to in this Section any special, exemplary, punitive or
         consequential damages.

         Lenders.

to clause (b) of the definition of "Blockage Period", payments on account of
current and accrued interest on the 14% Debentures:

                           (x) on any 14% Debenture Interest Payment Date in an
                  amount, and only up to an amount, equal to the excess, if any,
                  of the amount of interest scheduled to be paid on the 14%
                  Debentures on such 14% Debenture Interest Payment Date
                  (excluding any scheduled interest on the 14% Debentures unpaid
                  from prior 14% Debenture Interest Payment Dates, but including
                  interest

<PAGE>   6
                  accrued on such unpaid interest for the period since the
                  immediately preceding 14% Debenture Interest Payment Date)
                  over the aggregate amount of any Accelerated Amortization
                  Payments payable in respect of each of the two Test Periods
                  most recently ended prior to such 14% Debenture Interest
                  Payment Date, and

                           (y) on any 14% Debenture Interest Payment Date in an
                  amount, and only up to an amount, equal to the 14% Debenture
                  Quarterly Amount for such 14% Debenture Interest Payment Date,
                  so long as (1) no payment of interest on the 14% Debentures
                  pursuant to this clause (y) of this proviso has been made
                  during the one-year period preceding the date of such payment
                  and (2) after giving effect to such payment, the Borrower
                  shall have cash and Cash Equivalents standing to its account
                  in an aggregate amount not less than $10,000,000, and

                           (z) so long as no Default or Event of Default (as to
                  which, if any notice is required to be given by the Agent,
                  such notice has been given) shall have occurred and be
                  continuing before or after giving effect to such payment, in
                  an amount not in excess of a cash contribution to the common
                  equity of the Borrower by the Investors made contemporaneously
                  with such payment.

                  (c) No Event of Default which existed on the date any Default
Blockage Notice was given shall be the basis for giving any subsequent Default
Blockage Notice, unless such Event of Default shall have been cured or waived or
otherwise ceased to exist for a period of not less than 90 consecutive days
after the date such Default Blockage Notice was given.

                  (d) No more than one Default Blockage Notice may be given
within any consecutive 180-day period.

                  (e) The expressions "prior payment in full," "payment in
full," "paid in full" and any other similar terms or phrases when used herein
with respect to the Senior Obligations shall mean the payment in full, in cash
and in immediately available funds, of all of the Senior Obligations.

                  3. Additional Provisions concerning Subordination. (a) The
Subordinated Holders and the Borrower agree that upon the occurrence of any
Subordination Event:

                     (1) all Senior Obligations shall be paid in full before
any payment or distribution is made with respect to the Subordinated
Obligations; and

                     (2) any payment or distribution of assets of the Borrower,
whether in cash, property or securities, to which any Subordinated Holder would
be entitled except for the provisions hereof, shall be paid or delivered by the
Borrower, or any receiver, trustee in bankruptcy, liquidating trustee,
disbursing agent or other Person making such payment or distribution, directly
to the Agent, for the account of the Senior Lenders, to the extent necessary to
pay in full all Senior Obligations, before any payment or distribution shall be
made to any Subordinated Holder.


                                      -6-
<PAGE>   7
                  (b) Upon the occurrence of any event or proceeding described
in clause (1) or (2) of the definition of "Insolvency Event" commenced by or
against the Borrower:

                      (1) each Subordinated Holder irrevocably authorizes and
empowers the Agent (A) to demand, sue for, collect and receive every payment or
distribution on account of the Subordinated Obligations payable or deliverable
in connection with such event or proceeding and give acquittance therefor, and
(B) to file claims and proofs of claim in any statutory or non-statutory
proceeding and take such other actions (but excluding the right to vote any
claim of any Subordinated Holder in any such proceeding), in its own name as
Agent, or in the name of the Subordinated Holders or otherwise, as the Agent may
deem necessary or advisable for the enforcement of the provisions of this
Agreement; provided, however, that the foregoing authorization and empowerment
imposes no obligation on the Agent to take any such action, and provided,
further, however, that if the Agent shall take such action, the Agent shall use
its reasonable efforts to keep the Subordinated Holders reasonably informed in
connection with such action;

                      (2) each Subordinated Holder shall take such action, duly
and promptly, as the Agent may reasonably request from time to time (A) to
collect the Subordinated Obligations for the account of the Senior Lenders and
(B) to file appropriate proofs of claim in respect of the Subordinated
Obligations; and

                      (3) each Subordinated Holder shall execute and deliver
such powers of attorney, assignments or proofs of claim or other instruments as
the Agent may reasonably request to enable the Agent to enforce any and all
claims in respect of the Subordinated Obligations and to collect and receive any
and all payments and distributions which may be payable or deliverable at any
time upon or in respect of the Subordinated Obligations.

                  (c) If any payment or distribution, whether consisting of
money, property or securities, be collected or received by any Subordinated
Holder in respect of the Subordinated Obligations, except payments permitted to
be made at the time of payment as provided in paragraph 2(b), such Subordinated
Holder forthwith shall deliver the same to the Agent for the account of the
Senior Lenders, in the form received, duly endorsed to the Agent, if required,
to be applied to the payment or prepayment of the Senior Obligations until the
Senior Obligations are paid in full. Until so delivered, such payment or
distribution shall be held in trust by such Subordinated Holder as the property
of the Senior Lenders, segregated from other funds and property held by such
Subordinated Holder.

                  4. Subrogation. Subject to the prior payment in full of the
Senior Obligations, the Subordinated Holders shall be subrogated to the rights
of the Senior Lenders to receive payments or distributions of assets of the
Borrower in respect of the Senior Obligations. For the purposes of such
subrogation, payments or distributions to the Agent, for the account of the
Senior Lenders, of any money, property or securities to which any Subordinated
Holder would be entitled except for the provisions of this Agreement shall be
deemed, as between the Borrower and its creditors other than the Senior Lenders
and such Subordinated Holder, to be a payment by the Borrower to or on account
of Subordinated Obligations, it being understood that the provisions of this
Agreement are, and are intended


                                      -7-
<PAGE>   8
solely, for the purpose of defining the relative rights of the Subordinated
Holders, on the one hand, and the Senior Lenders, on the other hand.

                  5. Consent of Subordinated Holders.

                  (a) Each Subordinated Holder consents, notwithstanding any
provision to the contrary contained in the Subordinated Debt Documents, to the
execution, delivery and performance of the Senior Loan Documents and to the
incurrence and existence of the Senior Obligations.

                  (b) Each Subordinated Holder consents that, without the
necessity of any reservation of rights against any Subordinated Holder, and
without notice to or further assent by any Subordinated Holder:

                      (1) any demand for payment of any Senior Obligations made
by the Agent or any Senior Lender may be rescinded in whole or in part by the
Agent or any such Senior Lender, and any Senior Obligation may be continued, and
the Senior Obligations, or the liability of the Borrower or any co-obligor or
any other party upon or for any part thereof, or right of offset with respect
thereto, or any obligation or liability of the Borrower or any other party under
the Senior Credit Agreements or any other agreement, may, from time to time, in
whole or in part, be renewed, extended, modified, accelerated, compromised,
waived, surrendered, or released by the Agent or any Senior Lender; and

                      (2) the Senior Credit Agreements, the Senior Notes and any
other Senior Loan Document may be amended, modified, supplemented or terminated,
in whole or in part, as the Agent or any Senior Lender may deem advisable from
time to time, provided, that no such amendment, supplement or other modification
shall increase the aggregate principal amount of the Commitments or Loans
available and outstanding thereunder, or increase the interest rate thereon,

in each case all without notice to or further assent by any Subordinated Holder,
which will remain bound under this Agreement, and all without impairing,
abridging, releasing or affecting the subordination provided for herein.

                  (c) Each Subordinated Holder waives any and all notice of the
creation, renewal, extension or accrual of any of the Senior Obligations and
notice of or proof of reliance by the Senior Lenders upon this Agreement. The
Senior Obligations, and any of them, shall be deemed conclusively to have been
created, contracted or incurred in reliance upon this Agreement, and all
dealings between the Borrower and the Senior Lenders shall be deemed to have
been consummated in reliance upon this Agreement. Each Subordinated Holder
acknowledges and agrees that the Senior Lenders have relied upon the
subordination provided for herein in entering into the Senior Credit Agreements
and in making funds available to the Borrower thereunder. Each Subordinated
Holder waives notice of or proof of reliance on this Agreement and protest,
demand for payment and notice of default.

                  6. Covenants of the Subordinated Holders and Whitehall. (a) So
long as any of the Senior Obligations shall remain outstanding, no Subordinated
Holder shall, without the prior written consent of the Agent:

                  (i) sell, assign, or otherwise transfer, in whole or in part,
the Subordinated Obligations or any interest therein to any other Person (a
"Transferee") or create, incur or suffer to exist any security interest, lien,
charge or other encumbrance whatsoever upon the Subordinated Obligations in
favor of any Transferee unless such transaction is made expressly subject to
this Agreement, and the Transferee expressly acknowledges to the Agent, by a
writing in form and substance reasonably satisfactory to the Agent, the
subordination provided for herein and agrees to be bound by all of the terms
hereof;

                  (ii) permit any of the Subordinated Debt Documents to be
amended, modified or otherwise supplemented; or

                  (iii) commence, or join with any creditors other than the
Senior Lenders in commencing any proceeding referred to in clause (1) or (2) of
the definition of "Insolvency Event."

                  (b) Whitehall covenants and agrees that, in the event of any
sale, assignment or transfer by any Subordinated Holder of any interest in the
Subordinated Obligations, Whitehall shall (i) give prompt written notice thereof
to the Agent.

                  7. Senior Obligations Unconditional. All rights and interests
of the Senior Lenders hereunder, and all agreements and obligations of the
Subordinated Holders and the Borrower hereunder, shall remain in full force and
effect irrespective of:

                  (a) any lack of validity or enforceability of any Senior Loan
Documents by reason of the commencement or pendency of any case, proceeding or
action described in clause (1) or (2) of the definition of 'Insolvency Event";

                  (b) subject to the proviso to Section 5(b)(2) hereof, any
change in the time, manner or place of payment of, or in any other term of, all
or any of the Senior Obligations, or any amendment or waiver or other
modification, whether by course of conduct or otherwise, of the terms of the
Senior Credit Agreements or any other Senior Loan Document;

                  (c) any exchange, release or nonperfection of any security
interest in any collateral for any Senior Obligations, or any release,
amendment, waiver or other modification, whether in writing or by course of
conduct or otherwise, of all or any of the Senior Obligations or any guarantee
thereof; or

                  (d) any other circumstances which otherwise might constitute a
defense available to, or a discharge of, the Borrower in respect of the Senior
Obligations, or of either any Subordinated Holder or the Borrower in respect of
this Agreement which is or is in the nature of a defense available to a surety.

                  8. Representations and Warranties. (a) The Holder represents
and warrants to the Agent and the Senior Lenders that:

                  (i) its 14% Debentures are owned by the Holder free and clear
of any Liens whatsoever arising from, through or under the Holder, other than
the interest of Whitehall, Goldman Sachs Capital Markets, L.P. and the interest
of the Senior Lenders under this Agreement.

                  (ii) The Holder has the corporate power and authority and the
legal right to execute and deliver and to perform its obligations under this
Agreement and has taken all necessary corporate action to authorize its
execution, delivery and performance of this Agreement.

                  (iii) This Agreement constitutes a legal, valid and binding
obligation of the Holder enforceable against the Holder in accordance with its
terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally, general equitable principles (whether considered in
a proceeding in equity or at law) and an implied covenant of good faith and fair
dealing.

                  (iv) The execution, delivery and performance of this Agreement
will not violate any provision of any Requirement of Law or Contractual
Obligation of the Holder and will not result in the creation or imposition of
any Lien on any of the properties or revenues of the Holder pursuant to any
Requirement of Law affecting or any Contractual Obligation of the Holder, except
the interest of the Senior Lenders under this Agreement.

                  (v) No consent or authorization of, filing with, or other act
by or in respect of, any arbitrator or Governmental Authority and no consent of
any other Person (including, without limitation, any stockholder or creditor of
the Holder), is required in connection with the execution, delivery,
performance, validity or enforceability of this Agreement.

                  9. No Representation by Agent. Neither the Agent nor any
Senior Lender has made, and none of them hereby or otherwise makes to the
Subordinated Holders, any representations or warranties, express, or implied,
nor does the Agent or any Senior Lender assume any liability to any Subordinated
Holder with respect to: (a) the financial or other condition of obligors under
any instruments of guarantee with respect to the Senior Obligations, (b) the
enforceability, validity, value or collectibility of the Senior Obligations or
the Subordinated Obligations, any collateral therefor, or any guarantee or
security which may have been granted in connection with any of the Senior
Obligations or the Subordinated Obligations or (c) the Borrower's title or right
to transfer any collateral or security.

                  10. Waiver of Claims. To the maximum extent permitted by law,
each Subordinated Holder waives any claim it might have against the Senior
Lenders with respect to, or arising out of, any action or failure to act or any
error of judgment, negligence, or mistake or oversight whatsoever on the part of
the Agent, the Senior Lenders or their respective directors, officers, employees
or agents with respect to any exercise of rights or


                                      -10-
<PAGE>   11
remedies under the Senior Loan Documents. Neither the Agent, any Senior Lender
nor any of their respective directors, officers, employees or agents shall be
liable for failure to demand, collect or realize upon any of such collateral or
for any delay in doing so or shall be under any obligation to sell or otherwise
dispose of any such collateral upon the request of the Borrower or any
Subordinated Holder or any other Person or to take any other action whatsoever
with regard to such collateral or any part thereof.

                  11. Provisions Applicable After Bankruptcy; No Turnover.

                  (a) The provisions of this Agreement shall continue in full
force and effect notwithstanding the occurrence of any Insolvency Event.

                  (b) To the extent that any Subordinated Holder has or acquires
any rights under Section 363 or Section 364 of the Bankruptcy Code with respect
to any collateral for any Senior Obligations or Subordinated Obligations, such
Subordinated Holder hereby agrees not to assert such rights without the prior
written consent of the Agent, on behalf of the Senior Lenders; provided that, if
requested by the Agent, such Subordinated Holder shall seek to exercise such
rights in the manner requested by the Agent, including the rights in payments in
respect of such rights.

                  12. Further Assurances. The Subordinated Holders and the
Borrower, at their own expense and at any time from time to time, upon the
written request of the Agent will promptly and duly execute and deliver such
further instruments and documents and take such further actions as the Agent
reasonably may request for the purposes of obtaining or preserving the full
benefits of this Agreement and of the rights and powers herein granted.

                  13. Provisions Define Relative Rights. This Agreement is
intended solely for the purpose of defining the relative rights of the Agent and
the Senior Lenders on the one hand and the Subordinated Holders on the other,
and no other Person shall have any right, benefit or other interest under this
Agreement.

                  14. Powers Coupled With An Interest. All powers,
authorizations and agencies contained in this Agreement are coupled with an
interest and are irrevocable until the Senior Obligations are paid in full and
the Commitments are terminated.

                  15. Authority of Agent. The Borrower and the Subordinated
Holders acknowledge that the rights and responsibilities of the Agent under this
Agreement with respect to any action taken by the Agent or the exercise or
non-exercise by the Agent of any option, request, judgment or other right or
remedy provided for herein or resulting or arising out of this Agreement shall,
as between the Agent and the Senior Lenders, be governed by the applicable
Senior Credit Agreement and by such other agreements with respect thereto as may
exist from time to time among them, but, as between the Agent, on the one hand,
and the Borrower and the Subordinated Holders, on the other hand, the Agent
shall be conclusively presumed to be acting as agent for the Lenders with full
and valid authority so to act or refrain from acting, and neither the Borrower
nor any Subordinated Holder shall be under any obligation, or entitlement, to
make any inquiry respecting such authority.

the Agent and the Senior Lenders and the Subordinated Holders with respect to
the subject matter hereof and there are no promises or representations by the
Agent or any Senior Lender or any Subordinated Holder relative to the subject
matter hereof not reflected herein.

                  20. Amendments in Writing; No Waiver: Cumulative Remedies. (a)
None of the terms or provisions of this Agreement may be waived, amended,
supplemented or otherwise modified except by a written instrument executed by
the Agent, the Borrower and each Subordinated Holder; provided that any
provision of this Agreement may be waived by the Agent and the Senior Lenders in
a letter or agreement executed by the Agent or by telex or facsimile
transmission from the Agent.

                  (b) No failure to exercise, nor any delay in exercising, on
the part of the Agent or any Senior Lender, any right, power or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of
any right, power or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power or privilege.

                  (c) The rights and remedies herein provided are cumulative,
may be exercised singly or concurrently and are not exclusive of any other

binding upon the successors and assigns of the Borrower and the Subordinated
Holders and shall inure to the benefit of the Agent and the Senior Lenders and
their successors and assigns.

                  (b) Upon a successor Agent becoming the Agent under either
Senior Credit Agreement, such successor Agent automatically shall become an
Agent hereunder with respect to such Senior Credit Agreement with all the rights
and powers of the Agent hereunder without the need for any further action on the
part of any party hereto. In the event that the "Agent" under one Senior Credit
Agreement is not the same as the "Agent" under the other Senior Credit
Agreement, the term "Agent" herein shall refer collectively to both such Agents.

                  23. Governing Law. This Agreement shall be governed by, and
construed and interpreted in accordance with, the law of the State of New York.
