         This Amendment No. 1 supplements and amends the Schedule 14D-1 Tender
Offer Statement (the "Schedule 14D-1") relating to a tender offer by
United/Harvey Holdings, L.P., a Delaware limited partnership ("Purchaser"), to
purchase all of the outstanding shares of Common Stock, par value $1.00 per
share (the "Shares"), of United Inns, Inc., a Delaware corporation (the
"Company"), at $25.00 per Share, net to the seller in cash, on the terms and
subject to the conditions set forth in Purchaser's Offer to Purchase, dated
November 21, 1994 (the "Offer to Purchase"), and in the related Letter of
Transmittal (which together constitute the "Offer").  Capitalized terms used
herein which are not otherwise defined herein are so used with the respective
meanings ascribed to them in the Offer to Purchase.

ITEM 4.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         Item 4 of the Schedule 14D-1 is hereby supplemented and amended by
adding the following:

         (b)     As disclosed in the Offer to Purchase (see Section 10
                 thereof), Hampstead Investment Partners Funding Corp., an
                 affiliate of Purchaser ("Hampstead Funding"), is party to a
                 bank credit agreement (the "Credit Agreement") with the
                 lenders party thereto and Bankers Trust Company, as agent
                 ("BTC"), providing for a revolving line of credit and letter
                 of credit facility.  Under the Credit Agreement, Hampstead
                 Funding and investment entities, including Purchaser, formed
                 by Hampstead through Hampstead Funding may borrow funds or
                 have letters of credit issued on their behalf for the purpose
                 of financing the costs and expenses of carrying on their
                 day-to-day business and pursuing and making investments,
                 including Purchaser's acquisition of Shares pursuant to the
                 Offer.  The lenders under the Credit Agreement have committed
                 to provide up to $125.0 million of loans and letters of credit
                 to Hampstead Funding and related investment partnerships.
                 Purchaser anticipates that, as of the Expiration Date, in
                 excess of $60.0 million will be available for borrowings by
                 Purchaser under the Credit Agreement.  In addition, affiliates
                 of Purchaser have unconditional commitments in excess of
                 $145.0 million for the provision of equity investments in
                 affiliated acquisition entities, including Purchaser.  The
                 payment for Shares acquired pursuant to the Offer will be
                 financed by a combination of the foregoing sources.

                          Loans under the Credit Agreement bear interest at a
                 rate determined by reference to, at the option of Hampstead
                 Funding from time to time, (i) BTC's base rate or (ii) BTC's
                 adjusted interbank offered rate plus 0.625%.  Interest on
                 loans under the Credit Agreement is payable monthly in
                 arrears.  The interest period for any adjusted interbank
                 offered rate loan will be one, two, three, six or, if
                 available, 12 months, as Hampstead Funding may elect.
                 Hampstead Funding is required to pay to the lenders commitment
                 fees of 0.25% per annum on the unused portion of the total
                 loan commitments, payable quarterly in arrears, and Hampstead
                 Funding or the appropriate investment entity is required to
                 pay a letter of credit fee of 0.625% per annum on the amount
                 of any outstanding letter of credit issued on its behalf,
                 payable quarterly in arrears.  Hampstead Funding and related
                 investment entities are also required to pay to BTC certain
                 fees in consideration of the administration of the Credit
                 Agreement.  The unpaid principal amount of loans under the
                 Credit Agreement, together with accrued and unpaid interest
                 thereon, is payable on July 3, 1998.  Hampstead Fundings'
                 obligations under the Credit Agreement are secured by the
                 grant to BTC of a security interest in certain of its assets.

                          Pursuant to the Credit Agreement, Hampstead Funding
                 is required to satisfy certain covenants, including without
                 limitation covenants to (i) deliver certain information
                 regarding Hampstead Funding and related investment entities to
                 BTC, (ii) timely pay all taxes, (iii) maintain rights and
                 privileges necessary in the ordinary course of business, (iv)
                 notify BTC of defaults or events of default under the Credit
                 Agreement, (v) notify BTC of certain changes in the financial
                 condition of Hampstead Funding or any related investment
                 entity, (vi) comply with the provisions of the Credit
                 Agreement, (vii) act prudently and in accordance with
                 customary industry standards in managing assets, (viii) give
                 BTC and other

                 lenders access to books and records, (ix) comply with law, (x)
                 maintain insurance consistent with customary standards, (xi)
                 obtain required governmental licenses and permits, and (xii)
                 preserve and protect the rights of the lenders under the
                 Credit Agreement.  The Credit Agreement also imposes certain
                 restrictions and limitations, including without limitation
                 restrictions and limitations on (i) the incurrence of
                 additional indebtedness by Hampstead Funding and related
                 investment entities, (ii) the creation of certain liens by
                 Hampstead Funding, (iii) any merger involving Hampstead
                 Funding, (iv) the modification of certain agreements to which
                 Hampstead Funding is a party, (v) the establishment of
                 employee benefit plans, (vi) the use of borrowings under the
                 Credit Agreement, and (vii) the incurrence of contingent
                 liabilities by Hampstead Funding and related investment
                 entities.

                          It is anticipated that any borrowings under the
                 Credit Agreement will be repaid, depending on business and
                 market conditions, with cash from operations, capital
                 transactions, additional borrowings or other financings or
                 such combination of the foregoing as Hampstead may deem
                 appropriate from time to time.

         (c)     Not applicable.

                  REVOLVING CREDIT LOAN AND LETTERS OF CREDIT

         2.01.   THE LOAN COMMITMENT.

                 (a)      LENDERS' LOAN COMMITMENTS.  Subject to the terms and
         conditions herein set forth, the Lenders agree, during the
         Availability Period, to (i) extend to Borrower or any Qualified
         Borrower a revolving line of credit, and (ii) cause the Agent to cause
         the Letter of Credit Issuer to issue Letters of Credit for the account
         of Borrower or any Qualified Borrower.

                 (b)      LIMITATION ON BORROWINGS AND RE-BORROWINGS.
         Notwithstanding anything to the contrary herein contained, Lenders
         shall not be required to extend any Borrowing or Rollover or cause the
         issuance of any Letter of Credit hereunder if:

                          (i)     after giving effect to such Borrowing,
                 Rollover or issuance of such Letter of Credit, the sum of (A)
                 the aggregate outstanding and unpaid principal balance of the
                 Loans PLUS (B) the Letter of Credit Liability would exceed the
                 Total Loan Commitment;

                          (ii)    such Borrowing would be disbursed within
                 thirty (30) days before the Loan Commitment Termination Date;

                          (iii)   the expiration date of such Letter of Credit
                 would be later than thirty (30) days before the Loan
                 Commitment Termination Date; or

                          (iv)    an Event of Default has occurred and is
                 continuing, or an event has occurred which, with the giving of
                 notice or passage of time, or both, would become an Event of
                 Default.

                 (c)      REDUCTION OF COMMITTED AMOUNT.  If any of the
         following events shall occur with respect to any Included Investor:

                      (i)     it shall (A) apply for or consent to the
                 appointment of a receiver, trustee, custodian, intervenor, or
                 liquidator of itself or of all or substantially all of its
                 assets, (B) file a voluntary petition in bankruptcy or admit
                 in writing that it is unable to pay its debts as they become
                 due, (C) make a general assignment for the benefit of
                 creditors, (D) file a petition or answer seeking
                 reorganization or an arrangement with creditors or take
                 advantage of any Debtor Relief Laws, (E) file an answer
                 admitting the material allegations of, or consent to, or
                 default in answering, a petition filed against it in any
                 bankruptcy, reorganization, or insolvency

                 proceeding, or (F) take personal, partnership, corporate or 
                 trust action, as applicable, for the purpose of effecting any 
                 of the foregoing;

                      (ii)    an order, order for relief, judgment, or decree
                 shall be entered by any court of competent jurisdiction or
                 other competent authority approving a petition seeking its
                 reorganization or appointing a receiver, custodian, trustee,
                 intervenor, or liquidator of it, or of all or substantially
                 all of its assets, and such order, judgment, or decree shall
                 continue unstayed and in effect for a period of sixty (60)
                 days;

                     (iii)    any final judgment(s) for the payment of money in
                 excess of fifteen percent (15%) of its net worth shall be
                 rendered against it, and such judgment or judgments shall not
                 be satisfied or discharged at least ten (10) days prior to the
                 date on which any of its assets could be lawfully sold to
                 satisfy such judgment;

                      (iv)    it shall repudiate, challenge, or declare
                 unenforceable its obligation to make cash contributions to
                 Borrower or a Partnership pursuant to its Remaining Capital
                 Commitment or a Capital Call Notice, or shall otherwise
                 disaffirm the provisions of the Commitment Agreement;

                       (v)    it shall fail to make a cash contribution to
                 Borrower or a Partnership when required pursuant to a Capital
                 Call Notice and such failure shall continue for three (3)
                 Business Days after the date required;

                      (vi)    any representation or warranty made under any
                 Loan Documents executed by it shall prove to be untrue or
                 inaccurate in any material respect, as of the date on which
                 such representation or warranty is made, and such Investor
                 shall fail to cure the adverse effect of the failure of such
                 representation or warranty within five (5) days after the
                 earlier of (A) Borrower's and such Investor's knowledge
                 thereof (as used in this SECTION, "Borrower's knowledge" shall
                 mean the current actual knowledge of a Hampstead Principal) or
                 (B) written notice thereof is delivered from Agent to Borrower
                 and to such Investor, or if such failure is not reasonably
                 able to be cured within five (5) days, then, provided Investor
                 commences the cure within such five (5) day period and
                 diligently pursues same, within fifteen (15) additional days;

                     (vii)    default shall occur in the performance of any of
                 the covenants or agreements contained in any of the Loan
                 Documents executed by it (except the financial covenants in
                 its Consent to Assignment, which are specifically addressed in
                 SUBSECTION (IX) below) and such default shall continue uncured
                 to the satisfaction of Agent for a period of five (5) days 
                 after the earlier of (A) Borrower's and such Investor's 
                 knowledge thereof or (B) written notice thereof has been given 
                 by Agent to Borrower and to such Investor;





                                       16
<PAGE>   17
                    (viii)    the occurrence of any circumstances or events
                 which (A) is likely to materially impair the ability of such
                 Investor to fulfill its obligations under the Loan Documents
                 executed by it, or (B) is likely to impair, impede, or
                 jeopardize the obligation and the liability of such Investor
                 to fulfill its obligations under the Commitment Agreement;
                 Agent shall use reasonable efforts to promptly notify Borrower
                 and such Investor in the event it believes any circumstance or
                 event described in this SUBSECTION (VIII) has occurred;
                 PROVIDED, HOWEVER, that Agent shall not be liable to Borrower,
                 any Investor or any other Person in the event it fails to do
                 so;

                      (ix)    default shall occur with respect to any of the
                 financial covenants contained in the Consent to Assignment of
                 such Investor.

         then the Agent may, and, upon the direction of the Majority Lenders,
         shall, upon notice to Borrower, treat such Included Investor's
         Remaining Capital Commitment as zero (in which case such Investor
         shall become an "EXCLUDED INVESTOR") for purposes of (i) calculating
         the aggregate Remaining Capital Commitments of the Included Investors
         when making future Borrowings or Rollovers or issuing Letters of
         Credit, (ii) calculating the Total Loan Commitment, and (iii)
         calculating whether a mandatory prepayment is required to be made by
         Borrower pursuant to SECTION 2.01(e) hereof.  If Agent determines that
         an event described in SUBSECTIONS (I) through (IX) above shall have
         occurred, Agent will promptly notify Lenders of the same.

                 (d)      REINSTATEMENT OF COMMITTED AMOUNT.  If Agent
         determines, in its sole discretion, that, after an Investor has become
         an Excluded Investor pursuant to SECTION 2.01(c) above, the default or
         other adverse event described in SECTION 2.01(c) which caused such
         exclusion has been cured or no longer exists, Agent shall, with the
         consent of the Majority Lenders, reinstate such Excluded Investor as
         an Included Investor.

                 (e)      MANDATORY PREPAYMENT.  If, on any day, the sum of (A)
         the aggregate outstanding and unpaid principal balance of the Loans
         PLUS (B) the Letter of Credit Liability exceeds the Total Loan
         Commitment, then Borrower shall pay such excess to the Agent, for the
         benefit of Lenders, in immediately available funds, (x) promptly, to
         the extent such funds are available in the Capital Commitments
         Account, and (y) within twenty-three (23) Business Days to the extent
         that it is necessary for Borrower to issue a Capital Call Notice to
         fund such required payment.

                 (f)      REDUCTION OF TOTAL COMMITMENT.  Borrower shall have
         the right, without Agent's consent, to designate any Investor an
         Excluded Investor and to consequently treat such Excluded Investor's
         Remaining Capital Commitment as zero solely for the purpose of
         reducing the Total Loan Commitment, if and only if, after giving
         effect thereto, (i) the aggregate outstanding and unpaid principal
         balance of the Loans, PLUS the Letter of Credit Liability shall not be
         in excess of the Total Loan Commitment as reduced, (ii) unless such
         reduction in the Total Loan Commitment would result in a Total Loan





                                       17
<PAGE>   18
         Commitment of zero (0), the aggregate Investor Funding Percentage of
         the Investors is equal to or greater than seventy-five percent (75%)
         of the Investor Funding Percentage in effect on the date of this
         Credit Agreement and (iii) Borrower shall notify the Agent in writing
         of its election to exclude such Investor's Remaining Capital
         Commitment thirty (30) days prior to the effective date of such
         exclusion.  The impact of designating an Investor as an Excluded
         Investor shall be only to reduce the Total Loan Commitment, and shall
         have no effect on the obligation of such Investor to respond to
         Capital Calls or otherwise comply with its obligations under its
         Consent Agreement or otherwise.

         2.02.   REVOLVING CREDIT COMMITMENT.  Subject to the terms and
conditions herein set forth, each Lender severally agrees to lend to Borrower
or any Qualified Borrower at any time and from time to time during the
Availability Period sums in an aggregate principal amount up to such Lender's
Loan Commitment at any such time; provided, however, that the outstanding and
unpaid principal balance of such Lender's Pro Rata Share of the Loans shall not
exceed at any one time such Lender's Loan Commitment, as of such date minus
such Lender's Pro Rata Share of the Letter of Credit Liability as of such date.
Subject to the foregoing limitation, Borrower or any Qualified Borrower may
borrow, repay without penalty or premium, and re-borrow hereunder, during the
Availability Period.  Each Borrowing pursuant to this SECTION 2.02 shall be
made ratably by Lenders in proportion to such Lender's Pro Rata Share of the
Total Loan Commitment.

         2.03.   MANNER OF BORROWING.  Borrower shall give Agent notice of the
date of each requested Borrowing hereunder, which date shall be a Funding Date
if such requested Borrowing is to be a Eurodollar Loan.  Such notice may be by
telephone, if confirmed in writing, facsimile, if confirmed by returned
facsimile, or other written communication (the "REQUEST FOR BORROWING"), and
such Request for Borrowing shall be irrevocable and effective upon receipt by
Agent.  Each Request for Borrowing shall be furnished to Agent at least four
(4) Eurodollar Business Days prior to the Funding Date of a Eurodollar Loan,
and at least two (2) Business Days prior to the requested date of funding of a
Floating Base Loan, and must specify the amount of such Borrowing, the Interest
Period therefor in the case of a Eurodollar Loan, whether the Borrowing shall
be a Eurodollar Loan or a Floating Base Loan, and the name of the applicable
Qualified Borrower, if any.

                 (a)      REQUEST FOR BORROWING.  Each Request for Borrowing
         shall be in the form attached hereto as EXHIBIT C (with blanks
         appropriately completed in conformity herewith) and shall be deemed to
         constitute a representation and warranty by Borrower that the
         representations and warranties set forth in Article VII hereof are
         true and correct in all material respects on and as of the date of
         such notice (except as Borrower may have otherwise notified Agent
         about changes in the matters addressed in SECTIONS 7.12 or 7.17), with
         the same force and effect as if made on and as of such date, and that
         no Event of Default or condition, event, or act which with the giving
         of notice or lapse of time, or both, would constitute an Event of
         Default, exists and is continuing at such date.  Each Request for
         Borrowing shall be irrevocable and binding on Borrower or the
         applicable





                                       18
<PAGE>   19
         Qualified Borrower, as the case may be, and Borrower or the applicable
         Qualified Borrower, as the case may be, shall indemnify Lenders
         against any cost, loss, or expense incurred by Lenders, or any of
         them, as a result of any failure to fulfill, on or before the date
         specified for such Borrowing, the conditions to such Borrowing set
         forth herein, including, without limitation, any cost, loss, or
         expense incurred by reason of the liquidation or re-deployment of the
         deposits or other funds acquired by Lenders, or any of them, to fund
         the Borrowing to be made by Lenders as a part of such Borrowing when
         such Borrowing, as a result of such failure, is not made on such date,
         except with respect to a Borrowing for a Floating Base Loan, as to
         which Borrower or the applicable Qualified Borrower, as the case may
         be, shall not be required to indemnify Lenders against such costs,
         losses or expenses incurred by Lenders as a result of such liquidation
         or redeployment of funds.  A certificate of a Lender setting forth the
         amount of any such cost, loss or expense, and the basis for the
         determination thereof, shall be delivered to Borrower or the
         applicable Qualified Borrower and the Agent and shall, in the absence
         of a manifest error, be conclusive and binding.

                 (b)      RATE REQUEST.  Prior to making a Request for
         Borrowing or delivering a Rollover Notice or a Conversion Notice,
         Borrower may (without specifying whether the anticipated Borrowing
         shall be a Floating Base Loan or Eurodollar Loan) request that the
         Agent provide it with the most recent Floating Base Rate and Adjusted
         Interbank Rate available to Lenders.  The Agent shall endeavor to
         provide such quoted rates to Borrower within two (2) Business Days of
         such request.

                 (c)      ROLLOVER.  At least four (4) Eurodollar Business Days
         prior to the termination of each Eurodollar Interest Period, Borrower
         or any applicable Qualified Borrower shall give the Agent written
         notice (the "ROLLOVER NOTICE") whether it desires to renew such
         Eurodollar Loan and shall designate the Interest Option which shall be
         applicable to such Rollover upon the expiration of such Interest
         Period.  The Rollover Notice shall also specify the length of the
         Interest Period selected by the Borrower or a Qualified Borrower with
         respect to such Rollover.  Each Rollover Notice shall be irrevocable
         and effective upon notification thereof to Agent and shall be deemed
         to constitute a representation and warranty by Borrower that the
         representations and warranties set forth in ARTICLE VII hereof are
         true and correct in all material respects on and as of the date of
         such notice (except as Borrower may have notified Agent about changes
         in the matters addressed in SECTIONS 7.12 or 7.17), with the same
         force and effect as if made on and as of such date.  If Borrower or a
         Qualified Borrower fails to timely give Agent the Rollover Notice, or
         if Borrower or a Qualified Borrower fails to repay a Eurodollar Loan 
         as provided in SECTION 4.01(b)(i), 4.02 or 4.03, then Borrower or the 
         applicable Qualified Borrower shall be deemed to have elected the 
         Floating Base Rate as the Interest Option with respect to such Loan 
         commencing on the expiration of the preceding Interest Period.

                 (d)      CONVERSION.  With respect to any Floating Base Loan,
         Borrower or the applicable Qualified Borrower shall have the right, on
         any Eurodollar Business Day (a "CONVERSION DATE"), to convert all or
         any portion of such Floating Base Loan to a





                                       19
<PAGE>   20
         Eurodollar Loan, by giving the Agent a Conversion Notice of such
         selection at least four (4) Eurodollar Business Days prior to such
         Conversion Date.

                 (e)      BORROWING LIMITATIONS.  Notwithstanding anything to
         the contrary contained herein, Borrower and each applicable Qualified
         Borrower shall be limited to no more than two (2) outstanding
         Eurodollar Loans each, hereunder at any one time during the
         Availability Period, and neither Borrower nor any applicable Qualified
         Borrower shall have the right to request a Eurodollar Loan if the
         interest rate applicable thereto under SECTION 2.06(a) hereof would
         exceed the Maximum Rate in effect on the first day of the Interest
         Period applicable to such Eurodollar Loan.

                 (f)      NOTICE TO LENDERS BY AGENT.  The Agent shall promptly
         notify each Lender of receipt of a Borrowing Notice or Rollover
         Notice, the amount of the Borrowing and such Lender's Pro Rata Share
         thereof, the date the Borrowing is to be made, the Interest Option
         selected, the Interest Period selected, if applicable, and the
         applicable rate of interest.

                 (g)      ASSESSMENT OF BORROWING PROCEDURE.  If, at any time,
         Agent determines, in its sole discretion, that the manner of borrowing
         described in this SECTION and in SECTION 2.04, in particular, without
         limitation, the number of Eurodollar Loans permitted and the minimum
         amount of each Loan, causes a burdensome degree of administrative
         complexity, Agent shall so notify Borrower, and Agent and Borrower
         shall, and Borrower shall cause each qualified Borrower to, amend the
         terms hereof to reduce or otherwise resolve the administrative burden.

                 (h)      JOINT BORROWINGS.  Agent shall have the sole
         authority to permit Qualified Borrowers to borrow a Eurodollar Loan or
         Eurodollar Loans jointly and severally, such joint and several
         Borrowing to be made pursuant to appropriate Qualified Borrower
         Promissory Notes, Guaranty Agreements and other Loan Documents.

         2.04.   MINIMUM LOAN AMOUNTS.  Each Eurodollar Loan shall be in an
amount of at least $5,000,000, and, if higher, an integral multiple of
$1,000,000 and each Floating Base Loan shall be in an amount of at least
$500,000, provided, however, that Borrower and the Qualified Borrowers may
borrow an aggregate of six (6) Eurodollar Loans in any one twelve-month period,
each in an amount less than $5,000,000, but greater than $1,000,000.

         2.05.   FUNDING.

                 (a)      LENDER FUNDING.  Each Lender shall make the proceeds
         of its Pro Rata Share of each Borrowing available to the Agent at its
         Funding Account for the account of Borrower or a Qualified Borrower on
         the borrowing date in immediately available funds, and upon
         fulfillment of all applicable conditions set forth herein, the Agent
         shall deposit such proceeds in immediately available funds in
         Borrower's or the applicable Qualified Borrower's account maintained
         at Bankers Trust.  If Borrower or a Qualified





                                       20
<PAGE>   21
         Borrower desires such funds to be wire transferred to another account
         on the same date, Borrower or the applicable Qualified Borrower shall
         deliver all applicable information by 11:00 a.m. (New York City time)
         on the date of the required Borrowing.  The failure of any Lender to
         advance the proceeds of its Pro Rata Share of any Borrowing required
         to be advanced hereunder shall not relieve any other Lender of its
         obligation to advance the proceeds of its Pro Rata Share of any
         Borrowing required to be advanced hereunder.  The liabilities and
         obligations of each of the Lenders hereunder shall be several and not
         joint, and neither the Agent nor any Lender shall be responsible for
         the performance by any other Lender of its obligations hereunder.
         Each of the Lenders hereunder shall be liable to the Borrower and any
         Qualified Borrower only for the amount of its respective Loan
         Commitment.  In the event that the conditions precedent to a Borrowing
         are not met and the Borrowing is not advanced by the Agent, Agent
         shall return to each Lender its Pro Rata Share of the Borrowing
         previously paid by such Lender to Agent.

                 (b)      FAILURE OF LENDER TO FUND.  Unless the Agent has been
         notified by any Lender before 2:00 p.m. (New York City time) on the
         date of a proposed Borrowing that such Lender does not intend to make
         available to the Administrative Agent on such date such Lender's
         portion of such Borrowing, the Agent may assume that such Lender will
         make such amount available to the Agent on such date and the Agent may
         (but shall not be obligated to) make available to the Borrower or
         Qualified Borrower a corresponding amount.  If and to the extent any
         Lender shall not have made its full amount available to the Agent and
         the Agent in such circumstances has made available to the Borrower or
         Qualified Borrower such amount, that Lender shall on the next Business
         Day following the date of such Borrowing make such amount available to
         the Agent, together with interest at the Federal Funds Rate for and
         determined as of each day during such period.  A certificate of the
         Agent submitted to any Lender with respect to amounts owing under this
         SECTION 2.05 shall be conclusive and binding, absent manifest error.
         If such amount is so made available, such payment to the Agent shall
         constitute such Lender's Loan on the borrowing date for all purposes
         of this Agreement.  If such amount is not made available to the Agent
         on the next Business Day following the borrowing date, the Agent shall
         notify the Borrower or Qualified Borrower of such failure to fund and,
         immediately upon such demand, if funds are available (and not
         otherwise specifically committed for some other purpose) in the
         Capital Commitments Account, and otherwise, within twenty-three (23)
         Business Days after, demand therefor by the Agent, the Borrower or
         Qualified Borrower shall pay such amount to the Agent's account,
         together with interest thereon for each day elapsed since the date of
         such Borrowing, at a rate per annum equal to the interest rate
         applicable at the time to the Loans comprising such Borrowing.





                                       21

         2.06.   INTEREST RATE.

                 (a)      RATE.  The unpaid principal of each Floating Base
         Loan shall bear interest at a rate per annum which shall from day to
         day be equal to the Floating Base Rate in effect from day to day.  The
         unpaid principal of each Eurodollar Loan shall bear interest at a rate
         per annum which shall be equal to the Adjusted Interbank Rate for the
         applicable Interest Period.

                 (b)      CHANGE IN RATE; PAST DUE AMOUNTS; CALCULATIONS OF
         INTEREST.  Each change in the rate of interest under each Note shall
         become effective, without prior notice to Borrower, automatically as
         of the opening of business of Agent on the date of said change.
         Interest on Loans shall be calculated from the date of Borrowing on
         the basis of actual days elapsed in a year consisting of 360 days.  If
         any principal of, or interest on, any Note is not paid when due, then
         (in lieu of the interest rate provided in SECTION 2.06(a) above) such
         past due principal and interest on the Note shall bear interest at the
         Default Rate.

         2.07.   DETERMINATION OF RATE.  The Agent shall determine each
interest rate applicable to the Borrowings hereunder.  The Agent shall give
prompt notice to the Borrower or the applicable Qualified Borrower of each rate
of interest so determined, and its determination thereof shall be conclusive
and binding in the absence of manifest error.

         2.08.   LETTERS OF CREDIT.

                 (a)      LETTER OF CREDIT COMMITMENT.  Subject to the terms
         and conditions hereof, on any Business Day during the Availability
         Period, the Agent shall cause the Letter of Credit Issuer to issue
         such Letters of Credit in such aggregate face amount as Borrower or a
         Qualified Borrower may request, each such Letter of Credit to have an
         expiration date not later than one year from the date of issuance,
         provided that after giving effect to the issuance of any such Letter
         of Credit, the Letter of Credit Liability will not exceed the lesser
         of (i) the remainder of (x) the Total Loan Commitment as of such date
         MINUS (y) the aggregate outstanding unpaid principal balance of the
         Loans as of such date, or (ii) fifty percent (50%) of the Total Loan
         Commitment.  In the event that Agent is not the Letter of Credit
         Issuer, any extension of a Letter of Credit must be approved by Agent.

                 (b)      REQUEST.  Each application for Letters of Credit
         ("REQUEST FOR LETTER OF CREDIT") shall be submitted to the Agent
         substantially in the form attached hereto as EXHIBIT D with respect to
         Borrower, and EXHIBIT G with respect to a Qualified Borrower (with
         blanks appropriately completed in conformity herewith), provided,
         however, that the form of the Letter of Credit and related annexes and
         notices may be amended as agreed between the requesting Borrower or
         Qualified Borrower and the Letter of Credit Issuer, together with an
         Application and Agreement for Letter of Credit for each Letter of
         Credit Issuer on or before 11:00 a.m. (New York City time) at least
         four (4) Business





                                       22
<PAGE>   23
         Days prior to the requested date of issuance.  Upon each such
         application Borrower shall be deemed to have automatically made to the
         Agent, each Lender and the Letter of Credit Issuer the following
         representations and warranties:

                       (i)    As of the date of issuance of the Letter of
                 Credit requested, each representation and warranty set forth
                 in ARTICLE VII hereof, is true and correct in all material
                 respects (except as Borrower may have otherwise notified Agent
                 about changes in the matters addressed in SECTIONS 7.12 or
                 7.17), both immediately before and after the issuance of the
                 requested Letter of Credit, as though such representations and
                 warranties were made on and as of such date; and there exists
                 no Event of Default or event which with the giving of notice
                 or lapse of time, or both, would result in an Event of
                 Default.

                      (ii)    Following the issuance of the requested Letter of
                 Credit, the Letter of Credit Liability will not exceed the
                 lesser of (A) the remainder of (x) the Total Loan Commitment
                 as of such date MINUS (y) the aggregate outstanding unpaid
                 principal balance of the Loans as of such date, or (B) fifty
                 percent (50%) of the Total Loan Commitment.

                 (c)      PARTICIPATION BY LENDERS.  Each Lender shall and does
         hereby participate ratably with the Letter of Credit Issuer in each
         Letter of Credit issued and outstanding hereunder to the extent of its
         Pro Rata Share of the Letter of Credit Liability with respect to each
         such Letter of Credit, and shall share in all rights and obligations
         resulting therefrom, including, without limitation (i) the right to
         receive from the Agent its Pro Rata Share of any reimbursement of the
         amount of each draft drawn under each Letter of Credit, (ii) the right
         to receive from the Agent its Pro Rata Share of the Letter of Credit
         fee pursuant to SECTION 2.13 hereof, (iii) the right to receive from
         the Agent its additional costs pursuant to SECTION 2.08(e) hereof, and
         (iv) the obligation to pay the beneficiary of any Letter of Credit its
         Pro Rata Share of the Letter of Credit Liability of such Letter of
         Credit upon proper presentation to the Letter of Credit Issuer by
         promptly delivering to the Agent when it receives notice of any
         payment by the Agent or the Letter of Credit Issuer to any beneficiary
         of any Letter of Credit in immediately available funds, its Pro Rata
         Share thereof.

                 (d)      PAYMENT OF LETTER OF CREDIT.  In consideration for
         the issuance by the Letter of Credit Issuer of the Letters of Credit,
         Borrower hereby authorizes, empowers, and directs the Agent, for the
         benefit of Lenders and the Letter of Credit Issuer, to disburse
         directly to the Letter of Credit Issuer, with notice to Borrower, in
         immediately available funds an amount equal to the face amount of each
         draft drawn under each Letter of Credit plus all interest, costs,
         expenses, and fees due to the Letter of Credit Issuer pursuant to the
         applicable Application and Agreement for Letter of Credit, which
         amounts shall be due and payable by Lenders to the Letter of Credit
         Issuer on the Business Day on which the Letter of Credit Issuer honors
         any such draft or incurs or is owed any such interest, costs, expenses
         or fees.  The Agent will promptly notify





                                       23
<PAGE>   24
         Borrower of any disbursements made by Lenders pursuant to the terms
         hereof, provided that the failure to give such notice will not affect
         the validity of the disbursement.  Any such disbursement made by
         Lenders to the Letter of Credit Issuer on account of a Letter of
         Credit issued for the account of Borrower shall initially be deemed to
         be a Floating Base Loan pursuant to SECTION 2.03 hereof, and Borrower
         shall be deemed to have given to the Agent, in accordance with the
         terms and conditions of SECTION 2.03, a Request for Borrowing with
         respect thereto.  Any such disbursement made by Lenders to the Letter
         of Credit Issuer on account of a Letter of Credit issued for the
         account of a Qualified Borrower shall be a Floating Base Loan pursuant
         to the terms of the related Qualified Borrower Letter of Credit Note.
         The Agent and Lenders may conclusively rely on the Letter of Credit
         Issuer as to the amount due to the Letter of Credit Issuer by reason
         of any draft under a Letter of Credit or fees due to the Letter of
         Credit Issuer under any Letter of Credit or any Application and
         Agreement for Letter of Credit.

                 (e)      INCREASED COSTS.  Borrower, or Qualified Borrower, as
         the case may be, shall pay to the Agent, immediately upon such demand,
         if funds are available (and not otherwise specifically committed for
         some other purpose) in the Capital Commitments Account, and otherwise,
         within twenty-three (23) Business Days after demand therefor, amounts
         sufficient to compensate the Letter of Credit Issuer and the Lenders
         for any and all costs resulting from any law or rule or regulation or
         any guideline or request or in the interpretation thereof by any
         Governmental Authority, central bank or comparable agency charged with
         the administration of such law or rule or regulation or guideline or
         in Generally Accepted Accounting Principles or regulatory accounting
         principles which directly or indirectly (i) impose or modify or deem
         applicable any reserve, special deposit or similar requirement against
         letters of credit issued by the Letter of Credit Issuer or imposed
         upon any Lender by virtue of its participation arrangement provided in
         SECTION 2.08(c) hereof, (ii) increase the amount of capital required
         or expected to be maintained or funded by the Letter of Credit Issuer
         or any Lender and applicable to banks generally, or (iii) impose on
         the Letter of Credit Issuer or any Lender, some condition regarding
         this Credit Agreement or any Application and Agreement for Letter of
         Credit, and the result of any event referred to in (i), (ii) or (iii)
         above shall be to increase the cost to the Letter of Credit Issuer of
         issuing or maintaining the Letters of Credit, or to increase the cost
         to a Lender of maintaining its participation arrangement as provided
         in SECTION 2.08(c) hereof.  In addition, Borrower, or a Qualified
         Borrower, as the case may be, shall pay to the Agent on demand,
         amounts to compensate the Letter of Credit Issuer, and the Lenders for
         any additional costs resulting from any change after the date hereof
         in any law or regulation or in the interpretation thereof by any
         Governmental Authority charged with the administration of such law or
         regulation or in Generally Accepted Accounting Principles or
         regulatory accounting principles, the effect of which shall be to
         further increase the costs to the Letter of Credit Issuer of issuing
         or maintaining the Letters of Credit or to further increase the cost
         to a Lender of maintaining its participation arrangement as provided
         in SECTION 2.08(c) hereof.  A certificate as to such increased costs,
         which states the basis of calculation thereof, submitted by the Letter
         of Credit Issuer or an affected Lender to the Borrower, or a





                                       24
<PAGE>   25
         Qualified Borrower, as the case may be, shall be conclusive, absent
         manifest error, as to the amount thereof.  Such increase in cost
         shall, with respect to the Letter of Credit Issuer, be based upon a
         reasonable allocation of the Letter of Credit Issuer's aggregate costs
         related to the Letters of Credit and, with respect to each affected
         Lender be based upon the actual cost incurred.  Agent will use
         reasonable efforts to promptly notify Borrower of any additional cost
         reimbursement obligations of which it is aware, whether or not any
         Letters of Credit are then outstanding or under application.

                 (f)      ACCELERATION OF UNDRAWN AMOUNTS.  Should the Agent
         demand payment of the Obligation hereunder prior to the Loan
         Commitment Termination Date pursuant to SECTION 5.02 or SECTION 10.02
         hereof, the Agent, by written notice to the Borrower, may take one or
         more of the following actions (a) declare the obligation of the
         Lenders to cause Letters of Credit to be issued pursuant to SECTION
         2.01 hereof and this SECTION 2.08 terminated, whereupon such
         obligations shall forthwith terminate without any other notice of any
         kind, or (b) demand that the Borrower pay to the Agent for deposit in
         a segregated interest-bearing cash collateral account, as security for
         the Obligation, an amount equal to the Letter of Credit Liability then
         outstanding at the time such notice is given, whereupon such amount
         shall forthwith be due and payable into such account, without
         presentment, demand, protest or any other notice of any kind, all of
         which are hereby waived.  Unless otherwise required by law, upon the
         full and final payment of the Obligation, the Agent shall return to
         Borrower any amounts remaining in said cash collateral account.

         2.09.   PAYMENT OF GUARANTY AGREEMENT.  In consideration of Lenders'
agreement to advance funds to a Qualified Borrower pursuant to SECTIONS 2.02
and 2.03 hereof, to cause Letters of Credit to be issued for the account of a
Qualified Borrower pursuant to SECTION 2.08 hereof, and to accept Guaranty
Agreements in support thereof, Borrower hereby authorizes, empowers and directs
the Agent, for the benefit of Lenders, to disburse directly to Lenders, with
notice to Borrower, in immediately available funds an amount equal to the
amount due and owing under any Qualified Borrower Note or Guaranty Agreement,
together with all interest, costs, expenses and fees due to Lenders pursuant
thereto in the event the Agent shall have not received payment of such
Qualified Borrower Note when due.  The Agent shall have no obligation to make
any such disbursement.  The Agent will promptly notify Borrower of any
disbursement made to the Lenders pursuant to the terms hereof, provided that
the failure to give such notice shall not affect the validity of the
disbursement.  Any such disbursement made by the Agent to Lenders shall be
deemed to be a Floating Base Loan pursuant to SECTION 2.03 hereof, and Borrower
shall be deemed to have given to the Agent in accordance with the terms and
conditions of SECTION 2.03 a Request for Borrowing with respect thereto.  The
Agent may conclusively rely on Lenders as to the amount due Lenders under any
Qualified Borrower Note or Guaranty Agreement.

         2.10.   USE OF PROCEEDS, LETTERS OF CREDIT AND GUARANTY AGREEMENTS.
The proceeds of the Loans and the Letters of Credit shall be used by Borrower
only for working capital, to pay for the costs and expenses of Borrower's
day-to-day businesses (including, without

limitation, any costs and expenses under this Credit Agreement), and by each
Qualified Borrower in connection with the making or pursuit of Qualified
Investments, and its and any General Partner's costs and expenses of its
day-to-day businesses (including, without limitation, any costs and expenses
under this Credit Agreement).  Neither Lenders nor Agent shall have any
liability, obligation, or responsibility whatsoever with respect to Borrower's
or a Qualified Borrower's use of the proceeds of the Loans, the Letters of
Credit or execution and delivery of the Guaranty Agreements, and neither
Lenders nor Agent shall be obligated to determine whether or not Borrower's or
a Qualified Borrower's use of the proceeds of the Loans or the Letters of
Credit are for purposes permitted under the Commitment Agreement.  Nothing,
including, without limitation, any Borrowing, any Rollover, any issuance of any
Letter of Credit, or acceptance of any Guaranty Agreement or other document or
instrument, shall be construed as a representation or warranty, express or
implied, to any party by Lenders or Agent as to whether any investment by
Borrower qualifies as an Investment or is otherwise permitted by the terms of
the Commitment Agreement.

         2.11.   AGENT FEES.  Borrower and the Qualified Borrowers shall pay to
the Agent fees in consideration of the administration of the Total Loan
Commitment and its issuance and fronting of Letters of Credit, which fees shall
be payable in amounts and on the dates agreed to between Borrower and Agent in
letter agreements dated December 15, 1993.

         2.12.   LOAN COMMITMENT FEE.  In addition to the payments provided for
in ARTICLE III hereof, Borrower shall pay to the Agent, for the account of each
Lender a commitment fee during the Availability Period at the rate of one
quarter of one percent (0.25%) per annum, on the average daily amount of such
Lender's Pro Rata Share of the Total Loan Commitment which was unused (through
the extension of Loans or the issuance of Letters of Credit) during the
immediately preceding calendar quarter of Borrower calculated on the basis of
actual days elapsed in a year consisting of 360 days, and payable in arrears on
the first Business Day of each calendar quarter (for such amounts accrued
through the last day of the immediately preceding calendar quarter).  For
purposes of this SECTION, (a) the average daily amount of the Total Loan
Commitment which was unused shall equal (i) the average daily Total Loan
Commitment during a calendar quarter of Borrower, less (ii) the average daily
utilization of the Total Loan Commitment during such calendar quarter; (b) the
average daily Total Loan Commitment during a calendar quarter shall equal the
quotient of (i) the aggregate of the Total Loan Commitment on each day during
such calendar quarter, divided by (ii) the number of days in such calendar
quarter; and (c) the average daily utilization of the Total Loan Commitment
during a calendar quarter of Borrower shall equal the quotient of (i) the
aggregate on each day during such calendar quarter of (A) the aggregate
outstanding and unpaid principal balance of the Loans, plus (B) the Letter of
Credit Liability, divided by (ii) the number of days in such calendar quarter.

Borrower and Lenders acknowledge and agree that the commitment fees payable
hereunder are bona fide commitment fees and are intended as reasonable
compensation to Lenders for committing to make funds available to Borrower as
described herein and for no other purposes.

<PAGE>   27
         2.13.   LETTER OF CREDIT FEE.  Borrower or the appropriate Qualified
Borrower shall pay to the Agent, for the benefit of the Lenders, in
consideration for the issuance of Letters of Credit hereunder, a per annum fee
equal to the Letter of Credit Fee multiplied by the available amount of each
Letter of Credit, calculated on the actual number of days elapsed in a year
consisting of 360 days, and payable in arrears on the first Business Day of
each calendar quarter (for amounts accrued through the last Business Day of the
preceding calendar quarter), commencing on the first Business Day of the
calendar quarter after the calendar quarter in which such Letter of Credit is
issued and continuing on the first Business Day of each calendar quarter
thereafter during which such Letter of Credit is outstanding.

                                  ARTICLE III

                            NOTES AND NOTE PAYMENTS

         3.01.   REVOLVING CREDIT NOTES.  The Loans to be made by Lenders to
Borrower hereunder shall be evidenced by promissory notes of Borrower.  Each
Note issued by Borrower shall (a) be dated the date hereof, or the date of such
Lender's Assignment and Acceptance Agreement, as applicable, (b) be in the
amount of such Lender's Loan Commitment, (c) be payable to the order of such
Lender at the principal office of the Agent, (d) bear interest in accordance
with SECTION 2.06 hereof, and (e) be in the form of EXHIBIT B attached hereto
(with blanks appropriately completed in conformity herewith).  Borrower agrees,
from time to time, upon the request of the Agent or any affected Lender, to
reissue new Notes, in accordance with the terms and in the form heretofore
provided, to any Lender and any Assignee of such Lender in accordance with
SECTION 12.08(c) hereof, in renewal of and substitution for the Note previously
issued by Borrower to the affected Lender.

         3.02.   PAYMENT OF PRINCIPAL OF THE NOTES.  The unpaid principal
amount of each of the Notes, together with all accrued but unpaid interest
thereon, unless otherwise accelerated pursuant to the terms hereof, shall be
due and payable on the Loan Commitment Termination Date.

         3.03.   PAYMENT OF INTEREST ON THE NOTES.

                 (a)      INTEREST.  Interest on the Notes shall be due and
         payable on each Interest Payment Date (for interest accrued through
         the last day of the month preceding the Interest Payment Date), and on
         the Loan Commitment Termination Date.

                 (b)      DIRECT DISBURSEMENT.  If, at any time, the Agent
         shall not have received on the date due, any payment of interest upon
         the Loans or any fee described herein, Agent shall disburse funds from
         the Capital Commitments Account to Lenders to the extent available
         therein for payment of any such amount and thereafter may, within the
         limits of the Total Loan Commitment, disburse to Lenders, without
         notice to or the consent of Borrower, in immediately available funds
         an amount equal to the interest or fee due to Lenders, which
         disbursement (if made from other than the Capital Commitments Account)
         shall be deemed to be a Floating Base Loan pursuant to SECTION 2.03
         hereof, and Borrower shall be deemed to have given to Lenders in
         accordance with the terms and conditions of SECTION 2.03 a Request for
         Borrowing with respect thereto.

         3.04.   PAYMENTS ON THE NOTES.  All payments of principal of, and
interest on, the Notes, of fees and of all other amounts payable under this
Credit Agreement by Borrower and Qualified Borrowers to or for the account of
Lenders, or any of them, shall be made by Borrower and Qualified Borrowers to
Agent before 11:00 a.m. (New York City time) in federal or other immediately
available funds to the Funding Account.  Funds received after 11:00 a.m.





                                       28
<PAGE>   29
(New York City time) shall be treated for all purposes as having been received
by Agent on the first Business Day next following receipt of such funds.
Except as provided in SECTION 12.08 hereof, each Lender shall be entitled to
receive its Pro Rata Share of each payment received by the Agent hereunder for
the account of Lenders on the Notes.  Each payment received by Agent hereunder
for the account of a Lender shall be promptly distributed by the Agent to such
Lender.  Agent and each Lender hereby agree that payments to the Agent by
Borrower and Qualified Borrowers of principal of, and interest on, the Notes,
of fees and of all other amounts payable under this Credit Agreement by
Borrower and Qualified Borrowers to or for the account of Lenders in accordance
with the terms of the Credit Agreement, the Notes and the other Loan Documents
shall constitute satisfaction of Borrower's and Qualified Borrowers'
obligations with respect to any such payments, and Agent shall indemnify and
hold harmless Borrower and Qualified Borrowers from any claims asserted by any
Lender in connection with the Agent's duty to timely distribute and apportion
such payments to the Lenders in accordance with this SECTION.  Each payment of
principal and interest shall be applied to such of the Loans as Borrower or the
appropriate Qualified Borrower shall direct by notice to be received by Agent
on or before the date of such payment.  Notwithstanding the foregoing to the
contrary, during the existence of an Event of Default, any amounts paid or made
available to pay the Obligation shall be applied to the Obligation in the order
and manner as Agent and Lenders shall determine.

         3.05.   PREPAYMENTS.  Borrower or any Qualified Borrower may, without
premium or penalty so long as no Event of Default has occurred, upon four (4)
Business Days' prior written notice to the Agent, prepay the principal of the
Notes then outstanding, in whole or in part, at any time or from time to time;
provided, however, that if Borrower or any Qualified Borrower shall prepay the
principal of any Eurodollar Loan on any date other than the last day of the
Interest Period applicable thereto, Borrower or such Qualified Borrower, as the
case may be, shall make the payments required by SECTION 4.05 hereof.
Notwithstanding any provision to the contrary in this SECTION 3.05, if Borrower
or a Qualified Borrower desires to prepay a Floating Base Loan, provided no
Event of Default has occurred under this Credit Agreement, Borrower or a
Qualified Borrower shall only be required to provide written notice thereof to
the Agent of such prepayment twenty-four (24) hours in advance of such payment.
Prepayments of the entire outstanding principal of a Loan shall be made
together with accrued interest thereon.  Any interest accrued at the time of a
partial prepayment of any Loan shall be paid on the next succeeding Interest
Payment Date.

         3.06    TAXES.

                 (a) Any and all payments by Borrower or a Qualified Borrower
         hereunder and under the Notes shall be made free and clear of and
         without deduction for any and all present or future taxes, levies,
         imposts, deductions, charges or withholdings, and all liabilities with
         respect thereto, EXCLUDING, in the case of each Lender, (i) taxes
         imposed on its income, and franchise taxes





                                       29
<PAGE>   30
         imposed on it, by the jurisdiction under the laws of which the Lender
         is organized or any taxing authority or other political subdivision
         thereof and, in the case of each Lender, taxes imposed on its income,
         and franchise taxes imposed on it, by the jurisdiction of each
         Lender's applicable lending office or any political subdivision
         thereof and (ii) any taxes imposed by the United States of America by
         means of withholding at the source if and to the extent that such
         taxes shall be in effect and shall be applicable, on the date hereof,
         to payments to be made to each Lender (all such non-excluded taxes,
         levies, imposts, deductions, charges, withholdings and liabilities
         being hereinafter referred to as "TAXES").  If Borrower or a Qualified
         Borrower shall be required by law to deduct any Taxes from or in
         respect of any sum payable hereunder to a Lender, (A) the sum payable
         shall be increased as may be necessary so that after making all
         required deductions (including deductions applicable to additional
         sums payable under this SECTION 3.06) such Lender receives an amount
         equal to the sum it would have received had no such deductions been
         made, (B) Borrower or such Qualified Borrower, as the case may be,
         shall make such deductions and (C) Borrower or such Qualified
         Borrower, as the case may be, shall pay the full amount deducted to
         the relevant taxation authority or other authority in accordance with
         applicable law.

                 (b)      Notwithstanding anything to the contrary contained in
         this Credit Agreement, Borrower and each Qualified Borrower shall be
         entitled, to the extent it is required to do so by law, to deduct or
         withhold income or other similar taxes imposed by the United States of
         America from interest, fees or other amounts payable hereunder for the
         account of any Lender (without the payment of increased amounts to
         such Lender pursuant to clause (a) above) other than a Lender (i)
         which is a domestic corporation (as such term is defined in Section
         7701 of the Internal Revenue Code) for Federal income tax purposes or
         (ii) which has the Prescribed Forms on file with Borrower to the
         extent deduction or withholding of such taxes is not required as a
         result of the filing of such Prescribed Forms, provided that if
         Borrower, or any Qualified Borrower, as the case may be, shall so
         deduct or withhold any such taxes, it shall provide a statement to
         such Lender, setting forth the amount of such taxes so deducted or
         withheld, the applicable rate and any other information or
         documentation which such Lender may reasonably request for assisting
         such Lender to obtain any allowable credits or deductions for the
         taxes so deducted or withheld in the jurisdiction or jurisdictions in
         which such Lender is subject to tax.

                 (c)      In addition, Borrower and each Qualified Borrower, as
         the case may be, agrees to pay any present or future stamp or
         documentary taxes or any other excise or property taxes, charges or
         similar levies which arise from any payment made hereunder or from the
         execution, delivery or registration of, otherwise with respect to,
         this Credit Agreement (hereinafter referred to as "OTHER TAXES").

                 (d)      Borrower and each Qualified Borrower, as the case may
         be, will indemnify each Lender for the full amount of Taxes or Other
         Taxes (including, without limitation, any Taxes or Other Taxes imposed
         by any jurisdiction on amounts payable under this SECTION 3.06) paid
         by a Lender and any liability (including penalties, interest and
         expenses) arising therefrom or with respect thereto except as a result
         of the negligence or willful misconduct of such Lender, whether or not
         such Taxes or Other Taxes were
                




                                       30
<PAGE>   31
         correctly or legally asserted.  Payment pursuant to this
         indemnification shall be made immediately upon demand therefor, if
         funds are available (and not otherwise specifically committed for some
         other purpose) in the Capital Commitments Account, and otherwise
         within twenty-three (23) Business Days from the date such Lender makes
         written demand therefor.
        
                 (e)      Within thirty (30) days after the date of any payment
         of Taxes by or at the direction of Borrower or a Qualified Borrower,
         as the case may be, Borrower or such Qualified Borrower, as the case
         may be, will furnish to the applicable Lender, at its address referred
         to in SECTION 12.03 hereof, the original or a certified copy of a
         receipt evidencing payment thereof.

                 (f)      Each Lender shall endeavor in good faith (consistent
         with its internal policies and legal and regulatory restrictions) to
         select a jurisdiction for its lending office or change the
         jurisdiction for its lending office, as the case may be, so as to
         avoid the imposition of any Taxes or Other Taxes or to eliminate the
         amount of any such additional amounts which may thereafter accrue;
         PROVIDED that no such selection or change of the jurisdiction for its
         lending office shall be made if, in the reasonable judgment of such
         Lender, such selection or change would be disadvantageous to such
         Lender.

                 (g)      Without prejudice to the survival of any other
         agreement of Borrower and each Qualified Borrower hereunder, the
         agreements and obligations of Borrower and the Qualified Borrowers
         contained in this SECTION 3.06 shall survive the payment in full of
         the Obligation.

         3.07.   LENDING OFFICE.  Each Lender may (a) designate its principal
office or a foreign branch, subsidiary or Affiliate of such Lender as its
lending office (and the office to whose accounts payments are to be credited)
for any Eurodollar Loan, (b) designate its principal office or a domestic
branch, subsidiary or Affiliate as its lending office (and the office to whose
accounts payments are to be credited) for any Floating Base Loan and (c) change
its lending offices from time to time by notice to the Agent and the Borrower.
In such event, such Lender shall continue to hold the Note evidencing its loans
for the benefit and account of such foreign branch, subsidiary or Affiliate.
Each Lender shall be entitled to fund all or any portion of its Loan Commitment
in any manner it deems appropriate, but for the purposes of this Credit
Agreement such Lender shall, regardless of such Lender's actual means of
funding, be deemed to have funded its Loan Commitment in accordance with the
Interest Option, from time to time, selected by the Borrower or a Qualified
Borrower for such Borrowing period.

                                   ARTICLE IV

                    SPECIAL PROVISIONS FOR EURODOLLAR LOANS

         4.01.   INADEQUACY OF EURODOLLAR LOAN PRICING.  If with respect to an
Interest Period for any Eurodollar Loan the Agent determines that deposits in
Dollars (in the applicable amounts) are not being offered by Agent in the
applicable interbank Eurodollar market for such Interest Period, then the Agent
shall forthwith give notice thereof to Borrower or the applicable Qualified
Borrower, whereupon until the Agent notifies Borrower or the applicable
Qualified Borrower that the circumstances giving rise to such suspension no
longer exist, (a) the obligation of Lenders to make Eurodollar Loans shall be
suspended and (b) Borrower or the applicable Qualified Borrower shall, at their
sole options, either (i) repay in full the then outstanding principal amount of
such Eurodollar Loan, together with accrued interest thereon on the last day of
the then current Interest Period applicable to such Eurodollar Loan or (ii)
convert such Eurodollar Loan to a Floating Base Loan in accordance with the
terms of this Credit Agreement on the last day of the then current Interest
Period applicable to each such Eurodollar Loan.

         4.02.   ILLEGALITY.  If, after the date of this Credit Agreement, the
adoption of any applicable law, rule, or regulation, or any change therein, or
any change in the interpretation or administration thereof by any Governmental
Authority, central bank, or comparable agency charged with the interpretation
or administration thereof, or compliance by any Lender (or its Eurodollar
lending office) with any request or directive (whether or not having the force
of law) of any such Governmental Authority, central bank, or comparable agency
shall make it unlawful or impossible for any Lender (or its Eurodollar lending
office) to make, maintain, or fund any type of Eurodollar Loans, then such
Lender shall so notify the Agent, and the Agent shall forthwith give notice
thereof to the Borrower and the applicable Qualified Borrower and the Lenders.
Before giving notice to Agent pursuant to this SECTION, such Lender shall
designate a different Eurodollar lending office, if such designation will avoid
the need for giving such notice and will not be otherwise disadvantageous to
any material extent to such Lender (as determined in good faith by such
Lender).  Upon receipt of such notice, Borrower or the applicable Qualified
Borrower shall, at their sole options, either (a) repay in full the then
outstanding principal amount of the portion of such Eurodollar Loan made by the
affected Lenders, together with accrued interest thereon, or (b) convert the
portion of such Eurodollar Loan made by the affected Lenders to a Floating Base
Loan on either (i) the last day of the then current Interest Period applicable
to each such Eurodollar Loan if such Lender may lawfully continue to maintain
and fund such Eurodollar Loan to such day or (ii) immediately if such Lender
may not lawfully continue to fund and maintain such Eurodollar Loan to such
day.

         4.03.   INCREASED COSTS FOR EURODOLLAR LOANS.  If any Governmental
Authority, central bank, or other comparable authority shall at any time
impose, modify, or deem applicable any law, rule, regulation or guideline
regarding capital adequacy or reserve (including, without limitation, any
imposed by the Board of Governors of the Federal Reserve System or pursuant to
or arising out of the July 1988 report of the Basle Committee on Banking
Regulations and Supervisory Practices entitled "International Convergence of
Capital Measurement and Capital





                                       32
<PAGE>   33
Standards" but excluding any reserve requirement included in the Eurodollar
Reserve Requirement of each Lender (or its Eurodollar lending office)), special
deposit or similar requirement against assets of, deposits with or for the
account of, or credit extended by any Lender (or its Eurodollar lending
office), or shall impose on any Lender (or its Eurodollar lending office) or
the applicable interbank Eurodollar market any other condition affecting any
type of its Eurodollar Loan, its Note, or the obligation to make any type of
Eurodollar Loan; and the result of any of the foregoing is to increase the cost
to any Lender of making or maintaining any type of Eurodollar Loan, or to
reduce the amount of any sum received or receivable by Lender under this Credit
Agreement or under its Note with respect to any Eurodollar Loan, by an amount
reasonably deemed by such Lender to be material, then, immediately upon such
demand, if funds are available (and not otherwise specifically committed for
some other purpose) in the Capital Commitments Account, and otherwise, within
twenty-three (23) Business Days after demand by such Lender (with a copy to the
Agent), Borrower shall pay or shall cause the applicable Qualified Borrower to
pay to such Lender, such additional amount or amounts as will compensate such
Lender for such increased cost or reduction.  Each Lender will promptly notify
Borrower and Agent of any event of which it has knowledge, occurring after the
date hereof, which will entitle such Lender to compensation pursuant to this
SECTION and, in connection with Eurodollar Loans, will, to the extent possible,
designate a different Eurodollar lending office if such designation will avoid
the need for, or reduce the amount of, such compensation and will not be
otherwise disadvantageous to any material extent to such Lender (as determined
in good faith by such Lender).  A certificate of such Lender claiming
compensation under this SECTION and setting forth the additional amount or
amounts to be paid to it hereunder shall be conclusive in the absence of
manifest error.  If any Lender demands compensation under this SECTION, then
Borrower or other Qualified Borrower, as the case may be, may at any time, upon
at least four (4) Eurodollar Business Days' prior notice to Agent either (a)
repay in full the then outstanding principal amount of such Eurodollar Loan,
together with accrued interest thereon to the date of prepayment or (b) convert
such Eurodollar Loan to a Floating Base Loan in accordance with the provisions
of this Credit Agreement; provided however, that Borrower or other Qualified
Borrower, as the case may be, shall be liable for any Consequential Loss
arising pursuant to such actions.

         4.04.   EFFECT ON EURODOLLAR LOANS AND FLOATING BASE LOANS.  If notice
has been given pursuant to SECTIONS 4.01 or 4.02 hereof requiring the then
outstanding Eurodollar Loans of Lenders to be repaid or converted, then unless
and until such Lender notifies the Borrower and Agent that the circumstances
giving rise to such repayment no longer apply, all Borrowings of that Lender
shall be Floating Base Loans.  If such Lender notifies Borrower and the Agent
that the circumstances giving rise to such repayment no longer apply, Borrower
or any Qualified Borrower may thereafter select Borrowings from that Lender and
any other Lender to be Eurodollar Loans in accordance with the terms hereof.

         4.05.   PAYMENTS NOT AT END OF INTEREST PERIOD.  If Borrower or any
Qualified Borrower makes any payment of principal with respect to any
Eurodollar Loan on any day other than the last day of an Interest Period
applicable to such Eurodollar Loan, then Borrower or such Qualified Borrower
shall pay to the Agent for the account of such Lender after demand by such





                                       33
<PAGE>   34
Lender (with a copy to the Agent) the Consequential Loss incurred by such
Lender as a result of the timing of such payment.  A certificate of such Lender
setting forth the basis for the determination of the amount of Consequential
Loss shall be delivered to Borrower or the applicable Qualified Borrower and
the Agent and shall, in the absence of manifest error, be conclusive and
binding.  Any conversion of a Eurodollar Loan to a Floating Base Loan on any
day other than the last day of the Interest Period for such Eurodollar Loan
shall be deemed a payment for purposes of this SECTION.

         4.06.   INDEMNITY.  Without prejudice to any other provisions of this
ARTICLE IV, Borrower and each Qualified Borrower shall indemnify each Lender
against any loss or expense which such Lender may sustain or incur as a
consequence of any default by Borrower or such Qualified Borrower in making any
payment when due of any amount due under this Credit Agreement or in making any
scheduled Borrowing, Rollover, or conversion under this Credit Agreement, in
respect of any Eurodollar Loan, including, but not limited to, any loss of
profit, premium or penalty incurred by such Lender in respect of funds borrowed
by it for the purpose of making, funding or maintaining such Eurodollar Loan,
as determined by such Lender in the exercise of its sole but reasonable
discretion.  A certificate as to any such loss or expense shall be promptly
submitted by such Lender to Borrower or the applicable Qualified Borrower (with
a copy to the Agent) and shall, in the absence of manifest error, be conclusive
and binding as to the amount thereof.

         5.01.   LIENS AND SECURITY INTEREST.

                 (a)      CAPITAL COMMITMENTS AND CAPITAL CALLS.  To secure
         performance by Borrower of the payment of each Note and the
         Obligation, Borrower shall grant to the Agent, for the benefit of each
         of the Lenders, a first, exclusive, and prior security interest and
         lien in and to the Remaining Capital Commitments, the Capital
         Commitments Account, the Capital Call Notices and any other rights to
         call for additional capital contributions as contemplated in ARTICLE
         IV of or otherwise by the Commitment Agreement, pursuant to an
         assignment agreement (the "BORROWER SECURITY AGREEMENT") (in
         substantially the form attached hereto as EXHIBIT K) as amended by an
         amendment agreement in substantially the form attached hereto as
         EXHIBIT K-1, an assignment of bank account (in substantially the form
         attached hereto as EXHIBIT L), financing statements, and other
         documents satisfactory to Agent.

                 (b)      INVESTOR INTERESTS.  To secure performance by each
         Investor of its obligation to make Capital Contributions pursuant to
         Capital Calls made by Borrower or the Agent, Borrower shall request
         that each Investor acknowledge the pledge and assignment of the
         Remaining Capital Commitments of the Investors and the right to make
         Capital Calls by Borrower to the Agent, for the benefit of Lenders,
         consent to the terms of the Borrower Assignment Agreement and the
         other Loan Documents, and waive certain terms of the Commitment
         Agreement, by execution of a consent to assignment (a "CONSENT
         AGREEMENT") (in substantially the form attached hereto as EXHIBIT M).

                 (c)      COLLATERAL DOCUMENTS.  The assignment agreements,
         financing statements, and other documents and instruments from time to
         time executed and delivered pursuant to this Credit Agreement and any
         documents or instruments amending or supplementing the same are
         collectively referred to herein as the "COLLATERAL DOCUMENTS."

         5.02.   COLLATERAL ACCOUNT; CAPITAL CALLS.

                 (a)      COLLATERAL ACCOUNT.  In order to secure further the
         payment of the Notes and the performance by Borrower of the Obligation
         and to effect and facilitate Lenders' right of offset, Borrower shall
         require that all Investors wire-transfer to Bankers Trust Company, 280
         Park Avenue-23 West, New York, New York 10017, ABA No. 021001033,
         Account No.  99-799-800, for further credit to: Hampstead Investment
         Partners Funding Corp., Account No. 42-850222, reference Hampstead
         Capital Commitments Account (the "CAPITAL COMMITMENTS ACCOUNT"), all
         monies or sums paid or to be paid by any Investors to the capital of
         Borrower as Capital Contributions as and when Capital Contributions
         are called pursuant to the Capital Call Notices.  In addition,





                                       35
<PAGE>   36
         Borrower shall, upon receipt, deposit in the Capital Commitments
         Account any payments and monies which Borrower receives directly from
         the Investors as Capital Contributions.

                 (b)      CAPITAL CALLS.  In order that Lenders may monitor the
         collateral and the Capital Commitment, Borrower shall not initiate or
         make any Capital Call or otherwise request, notify, or demand that any
         Investor make any Capital Contribution, except through the Agent
         acting on behalf of Lenders.  At least three (3) Business Days prior
         to any proposed Capital Call Notice, Borrower shall furnish to the
         Agent (a) the original Capital Call Notice for each Investor from whom
         a Capital Contribution is being sought (substantially in the form
         attached hereto as EXHIBIT O with any blanks appropriately completed),
         and (b) self-addressed, stamped or otherwise prepaid envelopes to each
         such Investors for purposes of mailing such Capital Call Notices.
         Borrower and the Agent on behalf of Lenders shall jointly verify that
         the Capital Call Notices have been manually signed by Borrower, and
         manually acknowledged by the Agent on behalf of Lenders.  The Agent
         shall use its reasonable efforts to acknowledge and deliver (via the
         method directed by Borrower) such Investors Notices within two (2)
         Business Days of receipt, with copies to Borrower.  Any attempted
         Capital Call Notice by Borrower other than through the Agent as
         contemplated above shall be void as respect to either Borrower's or
         Investors' obligations under this SECTION 5.02 or the other Loan
         Documents.

                 (c)      NO LIABILITY OF AGENT OR LENDERS.  Notwithstanding
         anything to the contrary herein contained, it is expressly understood
         and agreed that, other than the obligation to use its reasonable
         efforts to acknowledge and mail the Capital Call Notices as described
         above, neither the Agent nor Lenders undertake any duties,
         responsibilities, or liabilities with respect to the Capital Call
         Notices.  Neither the Agent nor Lenders shall be required to refer to
         the Commitment Agreement, or take any other action with respect to any
         other matter that might arise in connection with the Commitment
         Agreement, or any Capital Call Notice.  Neither the Agent nor Lenders
         have any duty to determine or inquire into any happening or occurrence
         or any performance or failure of performance of any of the Investors.
         Neither the Agent nor Lenders has any duty to inquire into the use,
         purpose, or reasons for the making of any Capital Call Notice or the
         investment or use of the proceeds thereof.

                 (d)      USE OF ACCOUNT; CAPITAL CALLS BY AGENT.  Borrower may
         withdraw funds from the Capital Commitments Account, with the approval
         of the Agent, at any time or from time to time, so long as there does
         not exist an Event of Default or an event which, with the giving of
         notice or lapse of time or both, would become an Event of Default.

                 Borrower hereby irrevocably authorizes and directs Lenders,
         acting through the Agent, to charge from time to time the Capital
         Commitments Account and any other accounts of Borrower at any Lender
         for amounts due to Lenders or any of them hereunder and under the
         Notes.  The Agent, on behalf of Lenders, is hereby authorized, in the
         name of Lenders or the name of the Borrower, at any time or from time
         to time during the existence of an Event of Default, to notify any or
         all parties obligated to





                                       36
<PAGE>   37
         Borrower with respect to the Capital Commitments to make all payments
         due or to become due thereon directly to the Agent on behalf of
         Lenders, at a different account number, or to initiate one or more
         Capital Calls of the Capital Commitments in order to pay the Loans or
         the Letter of Credit Liability, or both.  With or without such general
         notification, and during the existence of an Event of Default, the
         Agent, on behalf of Lenders, may, subject to the limitations in the
         Consent Agreements, (i) take or bring in Borrower's name or that of
         Lenders all steps, actions, suits, or proceedings deemed by the Agent
         necessary or desirable to effect possession or collection of payments,
         (ii) complete any contract or agreement of Borrower in any way deemed
         necessary or desirable by the Agent to collect any of the Capital
         Calls, (iii) make allowances or adjustments related to the Capital
         Calls, or (iv) compromise any claims related to the Capital Calls.
         Regardless of any provision hereof, in the absence of gross negligence
         or willful misconduct by Agent or Lenders, neither the Agent nor
         Lenders shall ever be liable for failure to collect or for failure to
         exercise diligence in the collection of all or part of the Capital
         Calls or Capital Commitments or sums due or paid thereon, nor shall
         they be under any obligation whatsoever to anyone by virtue of the
         security interests and liens relating to the Capital Calls or Capital
         Commitments.

                 (e)      EVENT OF DEFAULT.  During the existence of an Event
         of Default, issuance by the Agent on behalf of Lenders of a receipt to
         any Person obligated to pay any Capital Commitment to Borrower shall
         be a full and complete release, discharge, and acquittance to such
         Person to the extent of any amount so paid to the Agent for the
         benefit of the Lenders.  The Agent, on behalf of Lenders, is hereby
         authorized and empowered, and during the existence of an Event of
         Default, on behalf of Borrower, to endorse the name of Borrower upon
         any check, draft, instrument, receipt, instruction, or other document
         or items relating to the Capital Calls or Capital Contributions,
         including, but not limited to, all items evidencing payment upon a
         Capital Commitment of any Person to Borrower coming into Agent's
         possession, and to receive and apply the proceeds therefrom in
         accordance with the terms hereof.  The Agent on behalf of Lenders is
         hereby granted an irrevocable Power of Attorney, which is coupled with
         an interest, to execute all checks, drafts, receipts, instruments,
         instructions, or other documents, agreements, or items relating to the
         Capital Calls or Capital Contributions on behalf of Borrower, either
         before or after demand of payment on the Notes but only during the
         occurrence of an Event of Default, as shall be deemed by the Agent to
         be necessary or advisable, in the sole discretion, reasonably
         exercised, of the Agent, to protect the security interests and liens
         in the Capital Commitments or the repayment of the Obligation, and
         neither the Agent nor Lenders shall incur any liability in connection
         with or arising from its exercise of such Power of Attorney in the
         absence of any gross negligence or willful misconduct by Agent or any
         such Lenders.

         The application by Lenders of such funds to the Obligation shall,
         unless the Agent shall agree otherwise in writing, be made in the
         order and manner determined by Agent and Lenders in their discretion.





                                       37
<PAGE>   38
                 (f)      NO REPRESENTATIONS.  Neither the Agent nor Lenders
         shall be deemed to make at any time any representation or warranty as
         to the validity of any Capital Call Notice nor shall the Agent or
         Lenders be accountable for Borrower's or any Qualified Borrower's use
         of the proceeds of any Capital Call.

         5.03.   LENDER OFFSET.  In addition to the rights granted to the Agent
and Lenders under SECTION 5.02 hereof, Borrower and each Qualified Borrower
hereby grants to each Lender a right of offset, to secure repayment of the
Obligation, upon any and all monies, securities, or other property of Borrower
or such Qualified Borrower and the proceeds therefrom, now or hereafter held or
received by or in transit to Lenders, from or for the account of Borrower or
such Qualified Borrower, whether for safekeeping, custody, pledge,
transmission, collection, or otherwise, and also upon any and all deposits
(general or specified) and credits of Borrower or such Qualified Borrower, and
any and all claims of Borrower or such Qualified Borrower against Lenders at
any time existing.  Lenders are hereby authorized at any time and from time to
time during the occurrence of an Event of Default, without notice to Borrower
or such Qualified Borrower, to offset, appropriate, apply, and enforce such
right of offset against any and all items hereinabove referred to against the
Obligation.  Borrower shall be deemed directly indebted to Lenders in the full
amount of the Obligation, and Lenders shall be entitled to exercise the rights
of offset provided for above.

         5.04.   AGREEMENT TO DELIVER ADDITIONAL COLLATERAL DOCUMENTS.
BORROWER shall deliver such security agreements, financing statements,
assignments, and other collateral documents (all of which shall be deemed part
of the Collateral Documents), in form and substance reasonably satisfactory to
the Agent, as the Agent acting on behalf of Lenders may reasonably request from
time to time for the purpose of granting to, or maintaining or perfecting in
favor of Lenders, first and exclusive security interests in any of the Capital
Call Notices, Capital Calls and Capital Commitments, together with other
assurances of the enforceability and priority of Lenders' liens and assurances
of due recording and documentation of copy of the Collateral Documents, as the
Agent may reasonably require to avoid material impairment of the liens and
security interests granted or purported to be granted pursuant to this ARTICLE
V.

         5.05.   SUBORDINATION OF ALL BORROWER CLAIMS.  As used herein, the
term "BORROWER CLAIMS" shall mean all debts and liabilities of an Investor to
Borrower or any General Partner, whether such debts and liabilities now exist
or are hereafter incurred or arise, or whether the obligations of such Investor
thereon be direct, contingent, primary, secondary, several, joint and several,
or otherwise, and irrespective of whether such debts or liabilities be
evidenced by note, contract, open account, or otherwise, and irrespective of
the Person or Persons in whose favor such debts or liabilities may, at their
inception, have been, or may hereafter be created, or the manner in which they
have been or may hereafter be acquired by Borrower or any General Partner.  The
Borrower Claims shall include without limitation all rights and claims of
Borrower against an Excluded Investor under Section 4.5 or otherwise of the
Commitment Agreement.

         Borrower agrees that any liens, security interests, judgment liens,
charges, or other encumbrances upon an Investor's assets securing payment of
the Borrower Claims, shall be and





                                       38
<PAGE>   39
remain inferior and subordinate in right and payment to any liens, security
interests, judgment liens, charges, or other encumbrances upon an Investor's
assets securing such Investor's obligations and liabilities to Lenders pursuant
to any of the Collateral Documents executed by such Investor, regardless of
whether such encumbrances in favor of Borrower or Lenders presently exist or
are hereafter created or attach.  Without the prior written consent of the
Agent, unless Lenders have released such Investor in writing, Borrower shall
not, at any time during the existence of an Event of Default, subject to the
terms herein limiting Borrower's rights to take the following actions without
Agent approval, (a) exercise or enforce any creditor's or partnership right it
may have against an Investor, (b) foreclose, repossess, sequester, or otherwise
take steps or institute any action or proceedings (judicial or otherwise,
including without limitation, the commencement of, or joinder in, any
liquidation, bankruptcy, rearrangement, debtor's relief, or insolvency
proceeding) to enforce any liens, mortgages, deeds of trust, security interest,
collateral rights, judgments or other encumbrances on assets of such Investor
held by Borrower, or (c) exercise any rights or remedies against an Investor
under Section 4.5 or otherwise of the Commitment Agreement.

         Upon the Agent's notification to Borrower that the Total Loan
Commitment has been reduced pursuant to SECTION 2.01(c) hereof and until the
mandatory prepayment pursuant to SECTION 2.01(e) hereof in connection
therewith, if any, shall be paid and satisfied in full, Borrower shall not
receive or collect, directly or indirectly, from any Investor any amount upon
the Borrower Claims.

                         REPRESENTATIONS AND WARRANTIES

         To induce Lenders to make the Loans and cause the issuance of Letters
of Credit hereunder, Borrower represents and warrants to Lenders that:

         7.01.   ORGANIZATION AND GOOD STANDING OF BORROWER.  Borrower is a
corporation duly organized, validly existing and in good standing under the
laws of the State of Texas, has the requisite corporate power and authority to
own its properties and assets and to carry on its business as now conducted,
and is qualified to do business in the State of Texas and in every jurisdiction
where the nature of the business conducted or the property owned or leased
requires such qualification and where the failure to be so qualified to do
business would have a Material Adverse Effect.

         7.02.   AUTHORIZATION AND POWER.  Borrower has the corporate power and
requisite authority to execute, deliver, and perform its obligations under this
Credit Agreement, the Notes, and the other Loan Documents to be executed by it;
Borrower is duly authorized to, and has taken all corporate action necessary to
authorize Borrower to execute, deliver, and perform its obligations under this
Credit Agreement, the Notes, and such other Loan Documents and are and will
continue to be duly authorized to perform its obligations under this Credit
Agreement, the Notes, and such other Loan Documents.

         7.03.   NO CONFLICTS OR CONSENTS.  None of the execution and delivery
of this Credit Agreement, the Notes, or the other Loan Documents, the
consummation of any of the transactions herein or therein contemplated, or the
compliance with the terms and provisions hereof or with the terms and
provisions thereof, will contravene or conflict with any provision of law,
statute, or regulation to which Borrower is subject or any judgment, license,
order, or permit applicable to Borrower or any indenture, mortgage, deed of
trust, or other agreement or instrument to which Borrower is a party or by
which Borrower may be bound, or to which Borrower may be subject.  No consent,
approval, authorization, or order of any court or Governmental Authority or
third party is required in connection with the execution and delivery by
Borrower of the Loan Documents or to consummate the transactions contemplated
hereby or thereby.

         7.04.   ENFORCEABLE OBLIGATIONS.  This Credit Agreement, the Notes,
the other Loan Documents and the Commitment Agreement are the legal and binding
obligations of Borrower enforceable in accordance with their respective terms,
subject to Debtor Relief Laws.

         7.05.   PRIORITY OF LIENS.  The Agent, for the benefit of Lenders, has
a valid, exclusive, enforceable, perfected, first priority security interest in
the Capital Commitments, the Capital Commitments Account, the Capital Call

<PAGE>   48
         7.06.   FINANCIAL CONDITION.  Borrower has delivered to Agent a copy
of its pro forma balance sheet as of December 1, 1993, and the related
statements of income, certified by the Chief Financial Officer thereof to be
true and correct.  The most recent financial statements of Borrower which
Borrower has delivered to Agent are true and correct, fairly present the
respective financial condition of Borrower as of such date and have been
prepared in accordance with Generally Accepted Accounting Principles.

         7.07.   FULL DISCLOSURE.  To Borrower's current, actual knowledge,
there is no material fact that Borrower has not disclosed to Agent in writing
which is likely to have a Material Adverse Effect.  Neither the financial
statements referred in SECTION 7.06 hereof, nor any certificate or statement
delivered herewith or heretofore by Borrower to Agent in connection with
negotiations of this Credit Agreement, contains any untrue statement of a
material fact or omits to state any material fact that is likely to have a
Material Adverse Effect.

         7.08.   NO DEFAULT.  No event has occurred and is continuing which
constitutes an Event of Default or which, with the lapse of time or giving of
notice or both, would constitute an Event of Default.

         7.09.   MATERIAL ADVERSE EFFECT.  No change to Borrower has occurred
which is likely to have a Material Adverse Effect since the date of the most
recent financial statements of Borrower delivered to Lenders.

 hereto, there are no actions, suits or legal, equitable, arbitration or
 administrative proceedings pending, or to the knowledge of Borrower
 threatened, against Borrower that would, if adversely determined, have a
 Material Adverse Effect.

         7.11.   TAXES.  To the extent that failure to do so would have a
Material Adverse Effect, all tax returns required to be filed by the Borrower
in any jurisdiction have been filed and all taxes (including mortgage recording
taxes), assessments, fees, and other governmental charges upon Borrower or upon
any of its properties, income or franchises have been paid prior to the time
that such taxes could give rise to a lien thereon.  There is no proposed tax
assessment against Borrower or any basis for such assessment which is likely to
have a Material Adverse Effect and is not being contested in good faith.

         7.12.   PRINCIPAL OFFICE.  The chief executive office of Borrower is
at 4200 Texas Commerce Tower West, 2200 Ross Avenue, Dallas, Texas 75201.

         7.13.   ERISA.  Borrower has not established and does not maintain any
Plan.

         7.14.   COMPLIANCE WITH LAW.  Borrower is in compliance in all
material respects with all laws, rules, regulations, orders, and decrees which
are applicable to Borrower or its properties, including, without limitation,

<PAGE>   49
Survey Act of 1976, as amended, and Environmental Laws, to the extent
non-compliance would be likely to have a Material Adverse Effect.

         7.15.   HAZARDOUS SUBSTANCES.  Borrower (a) has not received any
notice or other communication or otherwise learned of any Environmental
Liability which would individually or in the aggregate have a Material Adverse
Effect arising in connection with (i) any non-compliance with or violation of
the requirements of any Environmental Law, or any permit issued under any
Environmental Law, or (ii) the Release or threatened Release of any Hazardous
Material into the environment, and (b) has no threatened or actual liability in
connection with the Release or threatened Release of any Hazardous Material
into the environment which would individually or in the aggregate have a
Material Adverse Effect.

         7.16.   INSIDER.  Borrower is not an "executive officer," "director,"
or "person who directly or indirectly or acting through or in concert with one
or more persons owns, controls, or has the power to vote more than 10% of any
class of voting securities" (as those terms are defined in 12 U.S.C. Section
375b or in regulations promulgated pursuant thereto) of any Lender, of a bank
holding company of which any Lender is a subsidiary, or of any subsidiary, of a
bank holding company of which any Lender is a subsidiary, of any bank at which
any Lender maintains a correspondent account, or of any bank which maintains a
correspondent account with any Lender.

         all of its assets, and such order, judgment or decree shall continue
         unstayed and in effect for a period of sixty (60) days;

                 (i)      any final judgment(s) for the payment of money in

         judgments is likely to have a Material Adverse Effect; or

                 (j)      there shall occur any change in the condition

                                       57
<PAGE>   58
whereupon the same shall forthwith become due and payable without presentment,

accelerate or other notice of any kind all of which Borrower hereby expressly
waives, anything contained herein or in the Note to the contrary

         10.03.  PERFORMANCE BY AGENT.  Should Borrower fail to perform any
covenant, duty, or agreement contained herein or in any of the Loan Documents
and should such failure continue beyond any grace period granted herein, the
Agent may, but shall not be obligated to, perform or attempt to perform such
covenant, duty, or agreement on behalf of Borrower and Agent shall give
Borrower notice prior to any action taken by Agent.  In such event, Borrower
shall, at the request of the Agent pay, immediately upon such demand, if funds
are available (and not otherwise specifically committed for some other purpose)

Borrower, nor by any such action shall the Agent or the Lenders be deemed to
create a partnership arrangement with the Borrower.

                                   ARTICLE XI

                                   THE AGENT

         11.01.  APPOINTMENT AND AUTHORIZATION.  Each Lender hereby appoints
Bankers Trust to act as the Agent as herein specified, and each Lender hereby
irrevocably appoints and authorizes the Agent to take such action on its behalf
and to exercise such power under this Credit Agreement and the other Loan
Documents as are delegated to the Agent by the terms hereof or thereof,
together with such powers as are reasonably incidental thereto.  Neither the
Agent nor any of its respective directors, officers or employees shall be
liable for any action taken or omitted to be taken by it or them under or in
connection with this Credit Agreement or the Loan Documents, except for its or
their own gross negligence or willful misconduct.  Agent may perform any of its
duties under this Credit Agreement and Loan Documents by or through its agents
or employees.

         In being bound by this Credit Agreement, each Lender acknowledges and
agrees that it shall not have any right to deal with the Borrower with respect
to the rights, benefits and obligations of the Borrower under this Credit
Agreement or the other Loan Documents, but instead it has appointed the Agent
to act in its behalf under this Credit Agreement in accordance with the terms
hereof and thereof.

         11.02.  AGENT IN ITS INDIVIDUAL CAPACITY.  With respect to the Note
issued to Agent, Agent shall have the same rights and powers under this Credit
Agreement as any other Lender and may exercise the same as though it were not
an Agent; and the term "Lender" or "Lenders" shall, unless otherwise expressly
indicated, include the Agent in its capacity as a Lender.  The Agent and its
Affiliates may accept deposits from, lend money to, act as trustee under
indentures of, and generally engage in any kind of business with, Borrower, any
Qualified Borrower, any Investor, any General Partner, and any direct or
indirect Affiliates of any of them, and any such Person which may do business
with any of them, all as if the Agent were not an Agent hereunder and without
any duty to account therefor to the other Lenders.

         11.03.  NOTE HOLDERS.  The Agent may treat the payee of any Note as
the holder thereof until written notice of transfer shall have been filed in
the manner provided in SECTION 12.08(c), signed by such payee, and in form
satisfactory to Agent.

         11.04.  CONSULTATION WITH COUNSEL.  The Lenders agree that the Agent
may retain and consult with legal counsel, accountants and other professionals
selected by Agent and shall not be liable for any action taken or suffered in
good faith by it in accordance with the advice of such professionals.

         11.05.  DOCUMENTS.  The Agent shall not be under a duty to examine or
pass upon the validity, effectiveness, enforceability, genuineness or value of
any of the Loan Documents or any other instrument or document furnished
pursuant thereto, and the Agent shall be entitled


                                       59
<PAGE>   60
to assume that the same are valid, effective, enforceable and genuine and what
they purport to be.

         11.06.  RELIANCE ON AGENT.  Borrower shall be entitled to rely upon,
and to act or refrain from acting on the basis of, any notice, statement,
certificate, waiver or other document or instrument delivered by the Agent to
Borrower on behalf of the Lenders so long as the Agent is purporting to act in
its capacity as Agent pursuant to this Credit Agreement, and Borrower shall not
be responsible or liable to any Lender (or to any Participant, as defined in
SECTION 12.08(b) hereof or to any Assignee, as defined in SECTION 12.08(c)
hereof), or as a result of any action or failure to act (including actions or
omissions which would otherwise constitute defaults hereunder) which is based
upon such reliance upon the Agent.  Borrower shall be entitled to treat the
Agent as the properly authorized Agent pursuant to this Credit Agreement until
Borrower shall have received notice of resignation, and Borrower shall not be
obligated to recognize any successor Agent until Borrower shall have received
written notification satisfactory to it of the appointment of such successor
Agent.

         11.07.  RESIGNATION OF AGENT AND SUCCESSOR AGENTS.  Agent may resign
at any time by giving written notice thereof to Lenders and Borrower, subject
to the appointment and acceptance of a successor Agent as provided below, and
Agent shall continue to serve as Agent until such appointment and acceptance by
a successor Agent.  If Agent resigns, then Borrower and Majority Lenders shall
work diligently toward the appointment of a successor Agent, and if no
successor Agent shall have been so appointed and shall have accepted such
appointment within thirty (30) days after the retiring Agent gives notice of
resignation, then the Majority Lenders shall, on behalf of the Lenders, appoint
successor Agent.  If Agent resigns and no successor Agent(s) shall have been
appointed and shall have accepted such appointment as aforesaid within sixty
(60) days after the retiring Agent gives notice of resignation, then the
retiring Agent shall, on behalf of Lenders, appoint a successor Agent.  Upon
the acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all of the
rights, powers, privileges and duties of the retiring Agent and the retiring
Agent shall be discharged from any further duties and obligations arising
thereafter hereunder.  After any retiring Agent's resignation or removal
hereunder as Agent, the provisions of this ARTICLE XI shall continue in effect
for its benefit in respect to any actions taken or omitted to be taken by it
while it was acting as Agent.

         11.08.  RESPONSIBILITY OF AGENT.  It is expressly understood and
agreed that the obligations of the Agent under the Loan Documents are only
those expressly set forth in the Loan Documents and that the Agent shall be
entitled to assume that no Event of Default or event which, with the giving of
notice or lapse of time, or both, would constitute an Event of Default has
occurred and is continuing, unless the Agent has actual knowledge of such fact
or has received notice from a Lender that such Lender considers that an Event
of Default or such event has occurred and is continuing and specifying the
nature thereof.  As used herein "actual knowledge" shall mean the actual
knowledge of the account officers at the Agent who have the account
responsibility for Borrower.  The Lenders recognize and agree that, for
purposes of this Credit Agreement, the Agent shall not be required to determine
independently whether the


                                       60
<PAGE>   61
conditions described in SECTIONS 6.03(a) and (b), 6.04(a) and (b), 6.05(a) and
(b) and 6.06(a) and (b) thereof have been satisfied and, in disbursing funds to
Borrower or a Qualified Borrower or causing the Letters of Credit to be issued,
may rely fully upon statements contained in the relevant requests by Borrower
or a Qualified Borrower.  The Agent shall not incur any liability under or in
respect of this Credit Agreement or the other Loan Documents by acting upon any
notice, consent, certificate, warranty or other paper or instrument believed by
it to be genuine or authentic or to be signed by the proper parties, or with
respect to anything which it may do or refrain from doing in the reasonable
exercise of its judgment, or which may seem to it to be necessary or desirable
in the premises.  Furthermore, the Agent shall be fully justified by acting in
good faith upon any notice, consent, certificate or other instrument or writing
(which may be by telegram, telecopy, cable or telex) believed by the Agent to
be genuine and signed or sent by a Lender.  In the event that Agent has not
exercised its right to initiate a Capital Call under the circumstances
described in the second paragraph of SECTION 5.02(d), Majority Lenders may
direct the Agent to exercise any rights it has under that paragraph.

         The relationship between the Agent and each Lender is only that of
agent and principal and has no fiduciary aspects, and the Agent's duties
hereunder are acknowledged to be only ministerial and not involving the
exercise of discretion on its part.  Nothing in this Credit Agreement or
elsewhere contained shall be construed to impose on the Agent any duties or
responsibilities other than those for which express provision is made herein.
In performing its duties and functions hereunder, the Agent does not assume and
shall not be deemed to have assumed, and hereby expressly disclaims, any
obligation or responsibility toward or any relationship of agencies or trusts
with or for, Borrower.  As to any matters not expressly provided for herein
(including without limitations, enforcement or collection of the Notes), the
Agent shall not be required to exercise any discretion or take any action, but
shall be required to act or to refrain from acting (and shall be fully
protected in so acting or from refraining from acting) upon the instruction of
the Majority Lenders, and such instructions shall be binding upon all Lenders
and all holders of the Notes; provided, however, that Agent shall not be
required to take any action which exposes such Agent to personal liability or
which is contrary to this Credit Agreement or applicable law.

         11.09.  ADMINISTRATION OF CREDIT AGREEMENT.  The Agent shall carry out
its administrative duties to the Lenders hereunder in accordance with the terms
of this Credit Agreement and as otherwise required by applicable law.

                 The Agent shall not, without the prior written consent of all
Lenders, agree to the modification or waiver of any of the terms of this Credit
Agreement, the Notes or any other Loan Document, consent to any action or
failure to act by the Borrower, or exercise any rights in respect of the Loans
or under this Credit Agreement, the Notes or any other Loan Documents,
including, without limitation, the Collateral Documents, if the agreement,
consent or exercise of rights would (a) extend the time for payment for the
principal or interest on any Notes, or reduce or increase the principal amount
of the Notes (except as a result of the application of payments or prepayments
under this Credit Agreement), or reduce the rate of interest borne by any
Notes, or otherwise affect the terms of payment of the principal of or any


                                       61
<PAGE>   62
interest on any Notes; (b) release any liens granted under the Collateral
Documents, except as otherwise contemplated therein; (c) permit any Person to
become an Included Investor except for the Persons designated as Included
Investors on the date of this Credit Agreement; (d) amend or waive the
provisions of SECTIONS 9.02, 9.04, 9.05(a) OR 9.06; (e) change the percentages
specified in the definition of Majority Lenders; or (f) release any guarantor
of the Obligation.

                 The Agent shall not, without the prior written consent of the 
Majority Lenders, agree to the modification or waiver of any of the terms of
ARTICLE VIII, or SECTIONS 5.02(d)(iv), 9.01, 9.03, 9.05(b), 9.07, 9.08 OR 9.09
or consent to any action or failure to act by the Borrower, or exercise any
rights in respect of such Article or Sections.
        
                 Further, the Agent shall not, without the prior written 
consent of the affected Lender, agree to the modification or waiver of any of
the terms of this Credit Agreement, the Notes or any other Loan Document,
consent to any action or failure to act by the Borrower, or exercise any rights
in respect of the Loans or under this Credit Agreement, the Notes or any other
Loan Documents, if the agreement, consent or exercise of rights would reduce or
increase the amount or alter the term of the Loan Commitment of such Lender, or
alter the provisions relating to any fees (or any other payments) payable to
such Lender.
        
                 If the Agent shall request the consent of a Lender to any 
agreement, consent or exercise of rights covered by this Credit Agreement, and
not receive such consent or denial thereof in writing within ten (10) Business
Days of the making of such request by the Agent, as the case may be, such
Lender shall be deemed not to have given its consent to the request.  Any
modification not addressed above and any exercise of rights or discretion not
explicitly reserved to the Agent under the terms hereof, shall require the
written consent of the Majority Lenders.
        
         11.10.  NOTICE OF EVENT OF DEFAULT.  In the event that the Agent shall
have acquired actual knowledge of any Event of Default or of an event which,
with the giving of notice or the lapse of time, or both, would constitute an
Event of Default, the Agent shall promptly give notice thereof to the Lenders.
In the event that any Lender shall have acquired actual knowledge of any Event
of Default or of any event which, with the giving of notice of the lapse of
time, or both, will constitute an Event of Default, such Lender shall promptly
give notice thereof to the Agent.

         11.11.  INDEPENDENT INVESTIGATION.  Each Lender represents and
warrants to the Agent that it has made its own independent investigation and
assessment of the financial condition and affairs of the Borrower, the
Qualified Borrowers and the Investors in connection with the making and
continuation of its participation under this Credit Agreement and has not
relied exclusively on any information provided to such Lender by the Agent in
connection herewith or therewith, and each Lender represents, warrants and
undertakes to the Agent that it shall continue to make its own independent
appraisal of the credit-worthiness of the Borrower, the Qualified Borrowers and
the Investors while its Loan Commitment under this Credit Agreement is in
force.


                                       62
<PAGE>   63
         11.12.  SHARING OF OFFSETS.  Each Lender and Agent agrees that if it
shall, through the exercise of any right of counterclaim, offset, banker's lien
or otherwise, receive payment of a portion of the aggregate amount of principal
and interest due with respect to any Note or with respect to the Obligation of
Borrower under this Credit Agreement which constitutes a greater proportion of
the aggregate amount of principal, interest and fees then due to such Lender
under this Credit Agreement or its Note than the proportion received by any
other Lender in respect of the aggregate amount of principal, interest and fees
due with respect to such other Lender's Note or the Obligation of Borrower to
such other Lender under this Credit Agreement, then such Lender shall purchase
participations in the Notes and in the Loan Commitment and other rights and
obligations under this Credit Agreement held by such other Lenders so that all
such recoveries of principal and interest with respect to this Credit
Agreement, the Notes and Borrower's Obligation thereunder held by the Lenders
shall be pro rata according to each Lender's Loan Commitment (determined as of
the date hereof and regardless of any change in any Lender's Loan Commitment
caused by such Lender's receipt of a proportionately greater or lesser payment
hereunder).

         11.13.  REPURCHASE.  If for any reason a Lender shall fail or refuse
to abide by its obligations (a "LENDER DEFAULT") under this Credit Agreement,
and such Lender fails to cure such Lender Default within five (5) Business Days
of its occurrence, then, in addition to the rights and remedies that may be
available to the Agent and the Lenders at law or in equity, such defaulting
Lender's Pro Rata Share, during the existence of such Lender Default, shall be,
solely for the purpose of determining Majority Lenders, a percentage obtained
from the fraction (a) the numerator of which is the aggregate principal amount
of such Lender's outstanding Loans and Letter of Credit Liability and (b) the
denominator of which is $125,000,000.  The Agent shall have the right, but not
the obligation, in its sole discretion, to acquire at par all of such
defaulting Lender's Loan Commitment, including its Pro Rata Share in the
outstanding principal balance of the Loans, its Pro Rata Share of its
participation in the Letter of Credit Liability and all fees which have accrued
with respect thereto under this Credit Agreement.  In the event that the Agent
does not exercise its right to so acquire all of such defaulting Lender's
interests, then the Agent and each of the Lenders that is not in Default (a
"CURRENT PARTY") shall then, thereupon, have the right, but not the obligation,
in its sole discretion to acquire at par (or if more than one Current Party
exercises such right, each Current Party shall have the right to acquire, pro
rata) such defaulting Lender's Loan Commitment, including its Pro Rata Share in
the outstanding principal balance of the Loans, its Pro Rata Share of its
participation in the Letter of Credit Liability and all fees which have accrued
with respect thereto under this Credit Agreement.

         11.14.  INDEMNIFICATION.  Lenders agree to indemnify Agent (to the
extent not reimbursed by Borrower), ratably according to their respective Pro
Rata Shares, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses, or
disbursements of any kind or nature whatsoever which may be imposed on,
incurred by or asserted against Agent in any way relating to or arising out of
this Credit Agreement or the other Loan Documents or any action taken or
omitted by Agent under this Credit Agreement or the other Loan Documents,
provided that no Lender shall be liable for any


                                       63
<PAGE>   64
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from Agent's gross
negligence or willful misconduct.  If a Lender Defaults, such defaulting Lender
shall indemnify, defend and hold the Agent and each of the other Lenders
harmless from and against any and all losses, damages, liabilities, or expenses
(including, but not limited to, reasonable attorneys' fees and interest at the
Default Rate set forth in herein for funds advanced by the Agent or any one of
the Lenders on account of the defaulting Lender) which they may sustain or
incur by reason of or in consequence of the defaulting Lender's failure or
refusal to abide by its obligations under the Loan Documents. The Agent may set
off against payments due to the defaulting Lender, for the claims of the Agent
and the other Lenders against the defaulting Lender.  The exercise of the above
remedies shall not reduce, diminish or liquidate the defaulting Lender's Pro
Rata Share or the obligations for the sharing of losses and reimbursement for
costs, liabilities and expenses under this Credit Agreement and the other Loan
Documents.

         11.15.  BENEFIT OF ARTICLE XI.  The agreements contained in this
ARTICLE XI are solely for the benefit of Agent and the Lenders, and are not for
the benefit of, or to be relied upon by, the Borrower (except for the
agreements in SECTION 11.06 which explicitly relate to the Borrower), or any
other Person, including, without limitation, the agreements expressed in
SECTION 11.13.

                                  ARTICLE XII

                                 MISCELLANEOUS

         12.01.  WAIVER.  No failure to exercise, and no delay in exercising,
on the part of the Agent or Lenders, any right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise thereof preclude any
other further exercise thereof or the exercise of any other right.  The rights
of the Agent and Lenders hereunder and under the Loan Documents shall be in
addition to all other rights provided by law.  No modification or waiver of any
provision of this Credit Agreement, the Notes or any of the other Loan
Documents, nor consent to departure therefrom, shall be effective unless in
writing and no such consent or waiver shall extend beyond the particular case
and purpose involved.  No notice or demand given in any case shall constitute a
waiver of the right to take other action in the same, similar or other
instances without such notice or demand.  The Agent, acting on behalf of all
Lenders, with the approval of Lenders to the extent required in SECTION 11.09,
and Borrower may from time to time enter into agreements amending or changing
any provision of this Credit Agreement or the rights of Lenders or Borrower
hereunder, or may grant waivers or consents to a departure from the due
performance of the obligations of Borrower hereunder, any such agreement,
waiver or consent made with such written consent of the Agent being effective
to bind all Lenders.

         12.02.  PAYMENT OF EXPENSES; INDEMNITY.

                 (a)      Borrower agrees to pay all out-of-pocket costs and
         expenses of Agent and Lenders (including, without limitation, the
         reasonable attorneys' fees of Agent's and Lenders' legal counsel)
         reasonably incurred by them in connection with the presentation and
         enforcement of, and Agent and Lenders' rights under, this Credit
         Agreement, the Notes, and the other Loan Documents, and all
         out-of-pocket costs and expenses of Agent (including without
         limitation the reasonable fees and expenses of Agent's legal counsel)
         reasonably incurred by it in connection with the negotiation,
         preparation, execution and delivery of this Credit Agreement, the
         Notes, and the other Loan Documents and any and all amendments,
         modifications and supplements thereof or thereto including, without
         limitation, Agent's out-of-pocket costs and expenses relating to the
         assignment of interests under this Credit Agreement to Eligible
         Assignees.

                 (b)      Borrower agrees to indemnify Agent and each of the
         Lenders and their respective directors, officers, employees, attorneys
         and agents (each such Person, including without limitation the Agent
         and each of the Lenders, being called an "INDEMNITEE") against, and to
         hold each Indemnitee harmless from, any and all losses, claims,
         actions, judgments, suits, disbursements, penalties, damages (other
         than consequential damages), liabilities and related expenses,
         including reasonable attorneys' fees and expenses, incurred by or
         asserted against any Indemnitee arising out of, in any way connected
         with, or as a result of (i) the execution and delivery of this Credit
         Agreement or any other Loan Document or any agreement or instrument
         contemplated thereby, (ii) the use or misuse of the proceeds of the
         Loans, (iii) the fraudulent actions


                                       65
<PAGE>   66
         or misrepresentations of Borrower, any Qualified Borrower or any
         Investor in connection with the transactions contemplated by this
         Credit Agreement and the other Loan Documents, or (iv) any claim,
         litigation, investigation or proceeding relating to any of the
         foregoing, whether or not any Indemnitee is a party thereto; provided,
         however, that such indemnity shall not, as to any Indemnitee, apply to
         any such losses, claims, actions, judgments, suits, disbursements,
         penalties, damages, liabilities or related expenses arising from gross
         negligence or willful misconduct of such Indemnitee.  In addition to
         and without limiting the foregoing, Borrower hereby indemnifies and
         holds the Indemnitees harmless from and against, and agrees to
         reimburse any Indemnitee with respect to, any and all claims, demands,
         causes of action, judgments, suits, disbursements, penalties, loss,
         damage, liabilities, costs, or expenses not resulting from the gross
         negligence or willful misconduct of any Indemnitee (including
         attorneys' fees and court costs) of any and every kind or character,
         known or unknown, fixed or contingent, asserted against or incurred by
         such Indemnitee under any Environmental Law by reason of any and all
         matters arising out of (1) any act or omission of Borrower, any
         Qualified Borrower or any officer, director, partner or shareholder of
         Borrower or any Qualified Borrower, (2) or any act, omission, event,
         or circumstance occurring on or in relationship to any Property of
         Borrower or any Qualified Borrower or any facility owned or operated
         by Borrower or any Qualified Borrower and arising in connection with
         the relationship of Borrower, Qualified Borrowers and Lenders related
         to the Obligation or the exercise or attempted exercise by Lenders of
         their rights hereunder (including, without limitation, the presence
         on, or the Release or threatened Release from or on, any Property of
         Borrower or any Qualified Borrower or any facility owned or operated
         by Borrower or any Qualified Borrower of any Hazardous Materials),
         regardless of whether the act, omission, event, or circumstance
         constituted a violation of any Environmental Law at the time of
         existence or occurrence, including, without limitation (x) all
         foreseeable and all unforeseeable damages (other than consequential
         damages) directly or indirectly arising out of (A) the use,
         generation, storage, or disposal of Hazardous Materials on any of the
         Properties, the transportation of any Hazardous Materials to or from
         any of the Properties, or the Release, threatened Release, or
         discharge of any Hazardous Materials to or from any of the Properties
         by Borrower or any Qualified Borrower, any prior owner or operator of
         any of the Properties or any person on or about any of the Properties,
         or (B) any damage to any natural resource or the environment, and (y)
         the costs of any repair, cleanup, or other remediation or
         detoxification for which Borrower or any Qualified Borrower is liable,
         and the preparation of any closure or other required plans under any
         Environmental Law.  In addition, Borrower agrees that, in the event
         any Hazardous Material is caused to be removed from any Property by
         Borrower or any Qualified Borrower, or any entity controlled by or
         owned in whole or in part by, or under common control with, Borrower
         or such Qualified Borrower, the number assigned by the Environmental
         Protection Agency in connection with generation, storage, use,
         transportation, or disposal of Hazardous Material, as between
         Borrower, such Qualified Borrower and Lender, shall be solely in the
         name of Borrower or the appropriate Qualified Borrower and, as between
         Lenders and Borrower or any Qualified Borrower, Borrower shall assume
         any and all liability for the generation, transportation, disposal


                                       66
<PAGE>   67
         or handling, in any manner whatsoever of the removed Hazardous
         Material.  All such losses, claims, actions, judgments, suits,
         disbursements, damages, liabilities, costs and expenses referred to in
         this SECTION 12.02(b) are hereinafter referred to as "EXPENSES."
         Borrower understands and agrees that its liability to each Indemnitee
         hereunder or under any Environmental Law shall arise when an
         Indemnitee incurs or is billed for any Expenses, and Borrower agrees
         to pay to each Indemnitee within sixty (60) days following the
         Indemnitee's demand from time to time in an amount equal to such
         Expenses.  Promptly after receipt by any Indemnitee of notice of any
         claim or the commencement of any action, such Indemnitee shall, if a
         claim in respect thereof is to be made by the Indemnitee against
         Borrower, notify Borrower in writing of that claim or the commencement
         of that action.  If any such claim or action shall be brought against
         any Indemnitee, and it shall notify Borrower thereof, Borrower shall
         be entitled to participate therein and to assume the defense thereof
         with counsel reasonably satisfactory to such Indemnitee.
         Notwithstanding the preceding sentence, each Indemnitee shall have the
         right to employ its own counsel and to determine its own defense of
         such action in any such case, but the fees and expenses of such
         counsel shall be at the expense of such Indemnitee unless (i) the
         employment of such counsel shall have been authorized in writing by
         the Borrower or (ii) the Borrower after the aforementioned notice of
         the action, shall not have employed counsel reasonably satisfactory to
         such Indemnitee to have charge of such defense or (iii) the
         representation of the Indemnitee by Borrower's counsel would give rise
         to a conflict of interest or (iv) the Indemnitee's counsel shall have
         reasonably concluded that there appear to be defenses available to it
         which are different from or additional to those available to the
         Borrower (in which case the Borrower shall not have the right to
         determine the defense of such action on behalf of the Indemnitee), in
         any of which events the reasonable fees and expenses of the Indemnitee
         shall be borne by the Borrower.

                 (c)      The provisions of this SECTION 12.02 shall remain
         operative and in full force and effect regardless of the expiration of
         the Availability Period, the consummation of the transactions
         contemplated hereby, the repayment of the Loans, the occurrence of the
         Loan Commitment Termination Date, the invalidity, illegality, or
         unenforceability of any term or provision of this Credit Agreement or
         any other Loan Document, or any investigation made by or on behalf of
         the Lenders.  All amounts due under this SECTION 12.02 shall be
         payable immediately upon demand, if funds are available (and not
         otherwise specifically committed for some other purpose) in the
         Capital Commitments Account, and otherwise, within twenty-three (23)
         Business Days after written demand therefor.

         12.03.           NOTICE.  Any notice, demand, request or other
communication which any party hereto may be required or may desire to give

Qualified Borrower and each Lender hereby irrevocably waives any objections
which it may now or hereafter have to the laying of venue of any suit, action
or proceeding arising out of or relating to this Credit Agreement or the Notes
brought in the courts located in the State of New York, Borough of Manhattan in
New York City, and hereby further irrevocably waives any claim that any such
suit, action or proceeding brought in any such court has been brought in an
inconvenient forum.  BORROWER AND EACH QUALIFIED BORROWER HEREBY WAIVES TRIAL
BY JURY IN ANY SUIT, ACTION OR PROCEEDING BROUGHT IN CONNECTION WITH THIS
CREDIT AGREEMENT, THE NOTES OR ANY OF THE OTHER LOAN DOCUMENTS, WHICH WAIVER IS
INFORMED AND VOLUNTARY.

         12.06.  INVALID PROVISIONS.  If any provision of this Credit Agreement
is held to be illegal, invalid, or unenforceable under present or future laws
effective during the term of this Credit Agreement, such provision shall be
fully severable and this Credit Agreement shall be construed and enforced as if
such illegal, invalid or unenforceable provision had never comprised a part of
this Credit Agreement, and the remaining provisions of this Credit Agreement
shall remain in full force and effect and shall not be affected by the illegal,
invalid or unenforceable provision or by its severance from this Credit
Agreement, unless such continued effectiveness of this Credit Agreement, as
modified, would be contrary to the basic understandings and


                                       69
<PAGE>   70
intentions of the parties as expressed herein.  If any provision of this Credit
Agreement shall conflict with or be inconsistent with any provision of any of
the other Loan Documents, then the terms, conditions and provisions of this
Credit Agreement shall prevail.

         12.07.  ENTIRETY AND AMENDMENTS.  The Loan Documents embody the entire
agreement between the parties and supersede all prior agreements and
understandings, if any, relating to the subject matter hereof and thereof, and
this Credit Agreement and the other Loan Documents to which Borrower or any
Qualified Borrower is a party may be amended only by an instrument in writing
executed by Borrower or the party Qualified Borrower and the Agent.

         12.08.  PARTIES BOUND; ASSIGNMENT.

                 (a)      The provisions of this Credit Agreement shall be
         binding upon and inure to the benefit of the parties hereto and their
         respective successors and assigns, except that Borrower may not assign
         or otherwise transfer any of its rights under this Credit Agreement
         without the prior written consent of all Lenders.

                 (b)      Any Lender may at any time grant to one or more banks
         or other institutions (each a "PARTICIPANT") a participating interest
         in its Loan Commitment or any or all of its Loans.  In the event of
         any such grant by a Lender of a participating interest to a
         Participant, such Lender shall remain responsible for the performance
         of its obligations hereunder, and 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 Credit Agreement.
         Any agreement pursuant to which any Lender may grant such a
         participating interest shall provide that such Lender shall retain the
         sole right and responsibility to enforce the obligations of Borrower
         hereunder including, without limitation, the right to approve any
         amendment, modification or waiver of any provision of this Credit
         Agreement.  Borrower agrees that each Participant shall be entitled to
         the benefits of SECTIONS 2.08(e) and 5.03 and ARTICLE IV hereof with
         respect to its participating interest.  Agent shall not, without the
         consent of all Participants, agree to any modification or waiver of
         any of the terms of any Loan Document, any action or failure to act by
         the Borrower, or any exercise of rights in respect of the Loans or
         under any Loan Documents, if the agreement, consent or exercise of
         rights would (a) extend the time for payment for the principal or
         interest on any Notes, or reduce or increase the principal amount of
         the Notes (except as a result of the application of payments or
         prepayments under this Credit Agreement), or reduce the rate of
         interest borne by any Notes, or otherwise affect the terms of payment
         of the principal of or any interest on any Notes; (b) release any
         liens granted under the Collateral Documents, except as otherwise
         contemplated therein; or (c) release any guarantor of the Obligation.
         A Transfer which is not permitted by SUBSECTION (c) below shall be
         given effect for purposes of this Credit Agreement only to the extent
         of a participating interest granted in accordance with this SUBSECTION
         (b).


                                       70
<PAGE>   71
                 (c)      Any Lender may, with the prior written consent of the
         Agent, Transfer to one or more Eligible Assignees (each an "ASSIGNEE")
         all, or a proportionate part of all, of its rights and obligations
         under this Credit Agreement and its Note, and such Assignee shall
         assume such rights and obligations, pursuant to an Assignment and
         Acceptance Agreement, PROVIDED, HOWEVER, that, unless the Agent
         otherwise consents, and except for Transfers made by the Agent, or
         Transfers to a Person that is a Lender prior to the Transfer, any such
         Transfer shall be in a minimum principal amount of $10,000,000.
         Notwithstanding the foregoing, any Lender may, at any time, Transfer
         to an Affiliate of such Lender or to a Federal Reserve Bank, all, or a
         proportionate part of all, of its rights and obligations under this
         Credit Agreement and its Note, and such Assignee (other than a Federal
         Reserve Bank) shall assume such rights and obligations, pursuant to an
         Assignment and Acceptance Agreement.  Upon (i) execution and delivery
         of such Assignment and Acceptance Agreement, (ii) payment by such
         Assignee to such transferor Lender of an amount equal to the purchase
         price agreed between such transferor Lender and such Assignee and
         (iii) payment to Agent of a processing and recordation fee of (x)
         $2,500 if such Assignee is not then a Lender or (y) $1,000 if such
         Assignee is then a Lender, such Assignee shall be a Lender party to
         this Credit Agreement and shall have all the rights and obligations of
         a Lender with a Loan Commitment as set forth in such Assignment and
         Acceptance Agreement, and the transferor Lender shall be released from
         its obligations hereunder to a corresponding extent, and no further
         consent or action by any party shall be required.  Upon the
         consummation of any assignment pursuant to this SUBSECTION (C), the
         transferor Lender, the Agent and Borrower shall make appropriate
         arrangements so that, if required, new Notes are issued to such
         Assignee and the transferor Lender.

                 (d)      The Agent shall maintain at its principal offices in
         New York, New York or at such other location as the Agent shall
         designate in writing to each Lender and Borrower, a copy of each
         Assignment and Acceptance Agreement delivered to and accepted by it
         and a register for the recordation of the names and addresses of the
         Lenders, the amount of each Lender's Pro Rata Share of the Total Loan
         Commitment and the Loans, and the name and address of each Lender's
         agent for service of process in New York City (the "REGISTER").  The
         entries in the Register shall be conclusive and binding for all
         purposes, absent manifest error, and Borrower, the Agent and the
         Lenders may treat each person or entity whose name is recorded in the
         Register as a Lender hereunder for all purposes of this Credit
         Agreement.  The Register shall be available for inspection and copying
         by Borrower or any Lender during normal business hours upon reasonable
         prior notice to the Agent.  A Lender may change its address and its
         agent for service of process upon written notice to the Agent, which
         notice shall be effective upon actual receipt by the Agent, which
         receipt will be acknowledged by the Agent upon request.  Upon receipt
         of any Assignment and Acceptance Agreement the Agent shall, if such
         Assignment and Acceptance Agreement has been completed, fully-executed
         and is substantially in the form of EXHIBIT P hereto, (i) accept such
         an Assignment and Acceptance Agreement, (ii) record the information
         contained therein in the Register and (iii) give prompt notice thereof
         to Borrower.

         12.09.  MAXIMUM INTEREST.  Regardless of any provision contained in
any of the Loan Documents, Lender shall never be entitled to receive, collect
or apply as interest on the Notes any amount in excess of the Maximum Rate,
and, in the event that Lender ever receives, collects or applies as interest
any such excess, the amount which would be excessive interest shall be deemed
to be a partial prepayment of principal and treated hereunder as such; and, if
the principal amount of the Obligation is paid in full, any remaining excess
shall forthwith be paid to Borrower.  In determining whether or not the
interest paid or payable under any specific contingency exceeds the Maximum
Rate, Borrower and Lender shall, to the maximum extent permitted under
applicable law, (a) characterize any nonprincipal payment as an expense, fee or
premium rather than as interest; (b) exclude voluntary prepayments and the
effects thereof; and (c) amortize, prorate, allocate and spread, in equal
parts, the total amount of interest throughout the entire contemplated term of
the Notes so that the interest rate does not exceed the Maximum Rate; provided
that, if the Notes is paid and performed in full prior to the end of the full
contemplated term thereof, and if the interest received for the actual period
of existence thereof exceeds the Maximum Rate, Lender shall refund to Borrower
the amount of such excess or credit the amount of such excess against the
principal amount of the Notes and, in such event, Lender shall not be subject
to any penalties provided by any laws for contracting for, charging, taking,
reserving or receiving interest in excess of the Maximum Rate.

         12.10.  HEADINGS.  Section headings are for convenience of reference
only and shall in no way affect the interpretation of this Credit Agreement.

         12.11.  SURVIVAL.  All representations and warranties made by Borrower
herein shall survive delivery of the Notes, the making of the Loans and the
issuance of the Letters of Credit.

         12.12.  AVAILABILITY OF RECORDS; CONFIDENTIALITY.  Borrower
acknowledges and agrees that the Agent may provide to the Lenders and to Fitch
Investor Service, Inc., and that the Agent and each of the Lenders may provide
to any Participant or Assignee or proposed Participant or Assignee, originals
or copies of this Credit Agreement, all Loan Documents and all other documents,
certificates, opinions, letters of credit, reports, and other material
information of every nature or description, and may communicate all oral
information, at any time submitted by or on behalf of Borrower or any Qualified
Borrower or received by the Agent or a Lender in connection with the Loans, the
Letter of Credit Liability, the Remaining Capital Commitments or Borrower or
any Qualified Borrower; provided, however, that, prior to any such delivery or
communication, the Lender, Participant, or Assignee, as the case may be, shall
agree to preserve the confidentiality of all data and information which
constitutes Confidential Information.  Anything herein to the contrary
notwithstanding, the provisions of this SECTION 12.12 shall not preclude or
restrict any such party from disclosing any Confidential Information:  (a) with
the prior written consent of Borrower, (b) upon the order of or pursuant to the
rules and regulations of any Governmental Authority having jurisdiction  over
such party, (c) in connection with any audit by an independent public
accountant of such party, provided such auditor thereto agrees to be bound by
the provisions of this SECTION 12.12, (d) to examiners or auditors of any
applicable Governmental Authority which examines such party's books and


                                       72
<PAGE>   73
records while conducting such examination or audit, or (e) as otherwise
specifically required by law.

         12.13.  PUBLICITY.  Neither Agent, any Lender nor Borrower shall
publish any "tombstone" advertisements, issue any press releases or otherwise
publicize this Credit Agreement or the transactions contemplated herein without
the prior mutual written consent of Borrower and Agent.

         12.14.  MULTIPLE COUNTERPARTS.  This Credit Agreement may be executed
in any number of counterparts, all of which taken together shall constitute one
and the same agreement, and any of the parties hereto may execute this Credit
Agreement by signing any such counterpart.

         IN WITNESS WHEREOF, the parties hereto have caused this Credit
Agreement to be duly executed as of the day and year first above written.
