due and owing on the first business day thereafter. Failure by the Payor to pay
any sum due hereunder when due and payable which has not been cured by the Payor
within 30 days following actual receipt of written notice given by the Payee
shall constitute an event of default under this Note and the Payee may, at its
sole option exercised by notice to the Payor, declare the entire outstanding
principle balance hereof, together with all unpaid interest accrued hereon, to
be immediately due and payable in full. Upon the occurrence of an event of
default hereunder, the Payee may exercise all rights and remedies available to

have the right to prepay all or any portion of the amounts evidenced by this
Note at any time without premium or penalty; provided, however, such prepayment
shall include all interest accrued and unpaid hereunder as of the date of such
prepayment.

        Failure by Payor to pay any sum due hereunder when due and payable which
has not been cured by Payor within 30 days following actual receipt of written
notice given by Payee, or the occurrence of an event of default under that
certain pledge agreement (the "Pledge Agreement") made by Payor to Payee dated
as of the date hereof and any of the documents, relating to the indebtedness
evidenced by this Note shall constitute an Event of Default under this note and
Payee may, at its sole option exercised by notice to Payor, declare the entire
outstanding principal balance hereof, together with all unpaid interest accrued
hereon, to be immediately due and payable in full. Upon the occurrence of an
Event of Default, Payee may exercise all rights and remedies available to it
under the Pledge Agreement or otherwise.

        If this Note is collected by legal proceedings (including proceedings in
the probate or bankruptcy courts) then all costs and expenses of collection or
enforcement shall be added to the principal of, and be collectible as part of,
this Note.

        In case any one or more of the provisions of this Note shall be invalid,
illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein shall not in any way
be affected or impaired thereby.

        THIS NOTE IS MADE UNDER AND IS TO BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO
ITS CHOICE-OF-LAW RULES.

        IN WITNESS WHEREOF, the Payor has caused this instrument to be duly

               REVOLVING CREDIT AGREEMENT (this "Agreement") dated as of March
___, 2000 among VORNADO REALTY L.P., a limited partnership organized and
existing under the laws of the State of Delaware ("Borrower"), VORNADO REALTY
TRUST, a real estate investment trust organized and existing under the laws of
the State of Maryland and the sole general partner of Borrower ("General
Partner"), UBS AG, STAMFORD BRANCH, as agent for the Banks (in such capacity,
together with its successors in such capacity, "Administrative Agent"), CITICORP
REAL ESTATE, INC., as Syndication Agent, THE CHASE MANHATTAN BANK, as
Syndication Agent, BANK OF AMERICA, N.A., as Documentation Agent, UBS AG,
STAMFORD BRANCH (in its individual capacity and not as Administrative Agent,
"UBS") and the other lenders signatory hereto (UBS, said other lenders signatory
hereto and the lenders who from time to time become Banks pursuant to Section
3.07 or 12.05 and, if applicable, any of the foregoing lenders' Designated
Lender, each a "Bank" and collectively, the "Banks").

               Borrower, General Partner, UBS and the Administrative Agent
entered into a Revolving Credit Agreement dated as of July 17, 1997 (the
"Initial Credit Agreement"), which provided for a revolving line of credit in
the amount of up to Six Hundred Million Dollars ($600,000,000) in favor of
Borrower. The Initial Credit Agreement was amended by certain letter agreements.
In addition, pursuant to the terms and provisions of the Initial Credit
Agreement, certain of the lenders who are identified on the signature pages
hereof became "Banks" thereunder.

               Borrower thereafter requested certain additional amendments to
the Initial Credit Agreement to, among other things, increase the amount of the
credit provided thereby to up to One Billion Dollars ($1,000,000,000).
Borrower's request was agreed to pursuant to the terms and conditions of an
Amended and Restated Revolving Loan Agreement dated as of February 23, 1998 (the
"Prior Credit Agreement"), which superseded the Initial Credit Agreement in its
entirety.

               Now, Borrower has requested a new revolving line of credit in the
amount of One Billion Dollars ($1,000,000,000) to replace the Prior Credit
Agreement and the Administrative Agent and the Banks have agreed to Borrower's
request pursuant to the terms and conditions of this Agreement. General Partner
is fully liable for the obligations of Borrower under this Agreement by virtue
of its status as the sole general partner of Borrower.

               NOW, THEREFORE, in consideration of the premises and the mutual
agreements, covenants and conditions hereinafter set forth, the Prior Credit
Agreement (as previously modified) is hereby amended and restated in its
entirety and Borrower, General Partner, the Administrative Agent and each of the
Banks agree as follows:

               SECTION 2.01.  Ratable Loans; Bid Rate Loans; Purpose.   (a)
Subject to the terms and conditions of this Agreement, the Banks agree to make
loans to Borrower as provided in this Article II.

               (b) Each of the Banks severally agrees to make a loan to Borrower
(each such loan by a Bank, a "Ratable Loan") in an amount up to its Loan
Commitment pursuant to which the Bank shall from time to time advance and
re-advance to Borrower an amount equal to its Pro Rata Share of the excess (the
"Available Total Loan Commitment") of the Total Loan Commitment over the sum of
(1) all previous advances (including Bid Rate Loans) made by the Banks which
remain unpaid and (2) the outstanding amount of all Letters of Credit. Within
the limits set forth herein, Borrower may borrow from time to time under this
paragraph (b) and prepay from time to time pursuant to Section 2.09 (subject,
however, to the restrictions on prepayment set forth in said Section), and
thereafter re-borrow pursuant to this paragraph (b). The Ratable Loans may be
outstanding as: (1) Base Rate Loans; (2) LIBOR Loans; or (3) a combination of
the foregoing, as Borrower shall elect and notify Administrative Agent in
accordance with Section 2.13. The LIBOR Loan, Bid Rate Loan and Base Rate Loan
of each Bank shall be maintained at such Bank's Applicable Lending Office.

               (c) In addition to Ratable Loans pursuant to paragraph (b) above,
so long as Borrower's Credit Rating is BBB- or better by S&P and Baa3 or better
by Moody's, one or more Banks may, at Borrower's request and in their sole
discretion, make non-ratable loans which shall bear interest at the LIBOR Bid
Rate in accordance with Section 2.02 (such loans being referred to in this
Agreement as "Bid Rate Loans"). Borrower may borrow Bid Rate Loans from time to
time pursuant to this paragraph (c) in an amount up to the Available Total Loan
Commitment at the time of the borrowing (taking into account any repayments of
the Loans made simultaneously therewith) and shall repay such Bid Rate Loans as
required by Section 2.08, and it may thereafter re-borrow pursuant to this
paragraph (c) or paragraph (b) above; provided, however, that the aggregate
outstanding principal amount of Bid Rate Loans at any particular time shall not
exceed the Bid Borrowing Limit.

               (d) The obligations of the Banks under this Agreement are
several, and no Bank shall be responsible for the failure of any other Bank to
make any advance of a Loan to be

                                       17
<PAGE>   19

made by such other Bank. However, the failure of any Bank to make any advance of
the Loan to be made by it hereunder on the date specified therefor shall not
relieve any other Bank of its obligation to make any advance of its Loan
specified hereby to be made on such date.

               (e) Borrower shall use the proceeds of the Loans for general
capital and working capital purposes of Borrower and its Consolidated Businesses
and UJVs, including costs incurred in connection with real estate acquisitions
and/or developments. In no event shall proceeds of the Loans be used for any
illegal purpose or for the purpose, whether immediate, incidental or ultimate,
of buying or carrying "margin stock" within the meaning of Regulation U, or in
connection with any hostile acquisition.

               SECTION 2.02. Bid Rate Loans. (a) When Borrower has the
Borrower's Credit Rating required by Section 2.01(c) and wishes to request
offers from the Banks to make Bid Rate Loans, it shall transmit to
Administrative Agent by facsimile a request (a "Bid Rate Quote Request")
substantially in the form of EXHIBIT G-1 so as to be received not later than
10:30 a.m. (New York time) on the fifth Banking Day prior to the date for
funding of the Bid Rate Loan(s) proposed therein, specifying:

                  (1) the proposed date of funding of the Bid Rate Loan(s),
        which shall be a Banking Day;

                  (2) the aggregate amount of the Bid Rate Loans requested,
        which shall be Twenty-Five Million Dollars ($25,000,000) or a larger
        integral multiple of One Million Dollars ($1,000,000); and

                  (3) the duration of the Interest Period(s) applicable thereto,
        subject to the provisions of the definition of "Interest Period" in
        Section 1.01.

Borrower may request offers to make Bid Rate Loans for more than one (1)
Interest Period in a single Bid Rate Quote Request. No Bid Rate Quote Request
may be submitted by Borrower sooner than thirty (30) days after the submission
of any other Bid Rate Quote Request.

               (b) Promptly upon receipt of a Bid Rate Quote Request,
Administrative Agent shall send to the Banks by facsimile an invitation (an
"Invitation for Bid Rate Quotes") substantially in the form of EXHIBIT G-2,
which shall constitute an invitation by Borrower to the Banks to submit Bid Rate
Quotes offering to make Bid Rate Loans to which such Bid Rate Quote Request
relates in accordance with this Section 2.02.

               (c) (1) Each Bank may submit a Bid Rate Quote containing an offer
or offers to make Bid Rate Loans in response to any Invitation for Bid Rate
Quotes. Each Bid Rate Quote must comply with the requirements of this paragraph
(c) and must be submitted to Administrative Agent by facsimile not later than
2:00 p.m. (New York time) on the fourth Banking Day prior to the proposed date
of the Bid Rate Loan(s); provided that Bid Rate Quotes submitted by UBS (or any
Affiliate of Administrative Agent) in its capacity as a Bank may be submitted,
and may only be submitted, if UBS or such Affiliate notifies Borrower of the
terms of the offer or offers contained therein not later than one (1) hour prior
to the deadline for the other

                                       18

<PAGE>   20

Banks. Any Bid Rate Quote so made shall (subject to Borrower's satisfaction of
the conditions precedent set forth in this Agreement to its entitlement to an
advance) be irrevocable except with the written consent of Administrative Agent
given on the instructions of Borrower. Bid Rate Loans to be funded pursuant to a
Bid Rate Quote may, as provided in Section 12.16, be funded by a Bank's
Designated Lender. A Bank making a Bid Rate Quote shall specify in its Bid Rate
Quote whether the related Bid Rate Loans are intended to be funded by such
Bank's Designated Lender, as provided in Section 12.16.

               (2) Each Bid Rate Quote shall be in substantially the form of
EXHIBIT G-3 and shall in any case specify:

               (i) the proposed date of funding of the Bid Rate Loan(s);

               (ii) the principal amount of the Bid Rate Loan(s) for which each
        such offer is being made, which principal amount (w) may be greater than
        or less than the Loan Commitment of the quoting Bank, (x) must be in the
        aggregate Twenty-Five Million Dollars ($25,000,000) or a larger integral
        multiple of One Million Dollars ($1,000,000), (y) may not exceed the
        principal amount of Bid Rate Loans for which offers were requested and
        (z) may be subject to an aggregate limitation as to the principal amount
        of Bid Rate Loans for which offers being made by such quoting Bank may
        be accepted;

               (iii) the margin above or below the applicable LIBOR Interest
        Rate (the "LIBOR Bid Margin") offered for each such Bid Rate Loan,
        expressed as a percentage per annum (specified to the nearest 1/1,000th
        of 1%) to be added to (or subtracted from) the applicable LIBOR Interest
        Rate;

               (iv) the applicable Interest Period; and

               (v) the identity of the quoting Bank.

A Bid Rate Quote may set forth up to three (3) separate offers by the quoting
Bank with respect to each Interest Period specified in the related Invitation
for Bid Rate Quotes.

               (3) Any Bid Rate Quote shall be disregarded if it:

                (i) is not substantially in conformity with EXHIBIT G-3 or does
        not specify all of the information required by sub-paragraph (c)(2)
        above;

                (ii) contains qualifying, conditional or similar language
        (except for an aggregate limitation as provided in sub-paragraph
        (c)(2)(ii) above);

                (iii) proposes terms other than or in addition to those set
        forth in the applicable Invitation for Bid Rate Quotes (except for an
        aggregate limitation as provided in sub-paragraph (c)(2)(ii) above); or

                (iv) arrives after the time set forth in sub-paragraph (c)(1)
        above.

                                       19
<PAGE>   21

               (d) Administrative Agent shall on the Banking Day of receipt
thereof notify Borrower in writing of the terms of (x) any Bid Rate Quote
submitted by a Bank that is in accordance with paragraph (c) and (y) any Bid
Rate Quote that amends, modifies or is otherwise inconsistent with a previous
Bid Rate Quote submitted by such Bank with respect to the same Bid Rate Quote
Request. Any such subsequent Bid Rate Quote shall be disregarded by
Administrative Agent unless such subsequent Bid Rate Quote is submitted solely
to correct a manifest error in such former Bid Rate Quote. Administrative
Agent's notice to Borrower shall specify (A) the aggregate principal amount of
Bid Rate Loans for which offers have been received for each Interest Period
specified in the related Bid Rate Quote Request, (B) the respective principal
amounts and LIBOR Bid Margins so offered and (C) if applicable, limitations on
the aggregate principal amount of Bid Rate Loans for which offers in any single
Bid Rate Quote may be accepted.

               (e) Not later than 4:00 p.m. (New York time) on the fourth
Banking Day prior to the proposed date of funding of the Bid Rate Loan, Borrower
shall notify Administrative Agent of its acceptance or non-acceptance of the
offers so notified to it pursuant to paragraph (d). A notice of acceptance shall
be substantially in the form of EXHIBIT G-4 and shall specify the aggregate
principal amount of offers for each Interest Period that are accepted. Borrower
may accept any Bid Rate Quote in whole or in part; provided that:

                (i) the principal amount of each Bid Rate Loan may not exceed
        the applicable amount set forth in the related Bid Rate Quote Request or
        be less than Five Million Dollars ($5,000,000) and shall be an integral
        multiple of One Hundred Thousand Dollars ($100,000);

                (ii) acceptance of offers with respect to a particular Interest
        Period may only be made on the basis of ascending LIBOR Bid Margins
        offered for such Interest Period from the lowest effective cost; and

                (iii) Borrower may not accept any offer that is described in
        sub-paragraph (c)(3) or that otherwise fails to comply with the
        requirements of this Agreement.

                (f) If offers are made by two (2) or more Banks with the same
LIBOR Bid Margins, for a greater aggregate principal amount than the amount in
respect of which such offers are accepted for the related Interest Period, the
principal amount of Bid Rate Loans in respect of which such offers are accepted
shall be allocated by Administrative Agent among such Banks as nearly as
possible (in multiples of One Hundred Thousand Dollars ($100,000), as
Administrative Agent may deem appropriate) in proportion to the aggregate
principal amounts of such offers. Administrative Agent shall promptly (and in
any event within one (1) Banking Day after such offers are accepted) notify
Borrower and each such Bank in writing of any such allocation of Bid Rate Loans.
Determinations by Administrative Agent of the allocation of Bid Rate Loans shall
be conclusive in the absence of manifest error.

                (g) In the event that Borrower accepts the offer(s) contained in
one (1) or more Bid Rate Quotes in accordance with paragraph (e), the Bank(s)
making such offer(s) shall

                                       20
<PAGE>   22

make a Bid Rate Loan in the accepted amount (as allocated, if necessary,
pursuant to paragraph (f)) on the date specified therefor, in accordance with
the procedures specified in Section 2.04.

               (h) Notwithstanding anything to the contrary contained herein,
each Bank shall be required to fund its Pro Rata Share of the Available Total
Loan Commitment in accordance with Section 2.01(b) despite the fact that any
Bank's Loan Commitment may have been or may be exceeded as a result of such
Bank's making Bid Rate Loans.

               (i) A Bank who is notified that it has been selected to make a
Bid Rate Loan as provided above may designate its Designated Lender (if any) to
fund such Bid Rate Loan on its behalf, as described in Section 12.16. Any
Designated Lender which funds a Bid Rate Loan shall on and after the time of
such funding become the obligee under such Bid Rate Loan and be entitled to
receive payment thereof when due. No Bank shall be relieved of its obligation to
fund a Bid Rate Loan, and no Designated Lender shall assume such obligation,
prior to the time the applicable Bid Rate Loan is funded.

               SECTION 2.03. Advances, Generally. The Initial Advance shall be
in the minimum amount of One Million Dollars ($1,000,000) and in integral
multiples of One Hundred Thousand Dollars ($100,000) above such amount and shall
be made upon satisfaction of the conditions set forth in Section 4.01.
Subsequent advances shall be made no more frequently than weekly thereafter,
upon satisfaction of the conditions set forth in Section 4.02. The amount of
each advance subsequent to the Initial Advance shall be in the minimum amount of
One Million Dollars ($1,000,000) (unless less than One Million Dollars
($1,000,000) is available for disbursement pursuant to the terms hereof at the
time of any subsequent advance, in which case the amount of such subsequent
advance shall be equal to such remaining availability) and in integral multiples
of One Hundred Thousand Dollars ($100,000) above such amount. Additional
restrictions on the amounts and timing of, and conditions to the making of,
advances of Bid Rate Loans are set forth in Section 2.02.

               Each advance shall be subject, in addition to the limitations and
conditions applicable to advances of the Loans generally, to Administrative
Agent's receipt, on or immediately prior to the date the request for such
advance is made, of a certificate from the officer requesting the advance (1)
certifying that Borrower is in compliance with all covenants enumerated in
paragraph 3(b) of Section 6.09 and containing covenant compliance calculations
that include the pro-forma adjustments described below, which calculations shall
demonstrate Borrower's compliance, on a pro-forma basis, as of the end of the
most recently ended calendar quarter for which financial results have been
reported by Borrower as required hereunder, with such covenants and (2) setting
forth the use of the advance, the income projected to be generated from such
advance for purposes of determining Combined EBITDA and the type of income so
generated.

               In connection with each advance of Loan proceeds, the following
pro-forma adjustments shall be made to the covenant compliance calculations
required as of the end of the most recently ended calendar quarter for which
financial results are required hereunder to have been reported by Borrower:

                                       21
<PAGE>   23

                  (i) Total Outstanding Indebtedness and Unsecured Indebtedness
        shall be adjusted by adding thereto, respectively, all indebtedness and
        unsecured indebtedness that is incurred by Borrower in connection with
        the advance;

                  (ii) Combined EBITDA, for any period, shall be adjusted by
        adding the income to be included as provided in Borrower's certificate;
        and

                  (iii) Interest Expense for any period, shall be adjusted by
        adding thereto interest expense to be incurred by Borrower in connection
        with the advance.

               SECTION 2.04. Procedures for Advances. In the case of advances of
Ratable Loans, Borrower shall submit to Administrative Agent a request for each
advance, stating the amount requested and the expected purpose for which such
advance is to be used, no later than 10:00 a.m. (New York time) on the date, in
the case of advances of Base Rate Loans, which is one (1) Banking Day, and, in
the case of advances of LIBOR Loans, which is three (3) Banking Days, prior to
the date the advance is to be made. In the case of advances of Bid Rate Loans,
Borrower shall submit a Bid Rate Quote Request at the time specified in Section
2.02, accompanied by a statement of the expected purpose for which such advance
is to be used. Administrative Agent, upon its receipt and approval of the
request for advance, will so notify the Banks either by telephone or by
facsimile. Not later than 11:00 a.m. (New York time) on the date of each
advance, each Bank (in the case of Ratable Loans) or the applicable Bank(s) (in
the case of Bid Rate Loans) shall, through its Applicable Lending Office and
subject to the conditions of this Agreement, make the amount to be advanced by
it on such day available to Administrative Agent, at Administrative Agent's
Office and in immediately available funds for the account of Borrower. The
amount so received by Administrative Agent shall, subject to the conditions of
this Agreement, be made available to Borrower, in immediately available funds,
by Administrative Agent's crediting account number 2017537183 of Borrower
maintained at Fleet Bank.

               SECTION 2.05. Interest Periods; Renewals. In the case of the
LIBOR Loans, Borrower shall select an Interest Period of any duration in
accordance with the definition of Interest Period in Section 1.01, subject to
the following limitations: (1) no Interest Period may extend beyond the Maturity
Date; (2) if an Interest Period would end on a day which is not a Banking Day,
such Interest Period shall be extended to the next Banking Day, unless such
Banking Day would fall in the next calendar month, in which event such Interest
Period shall end on the immediately preceding Banking Day; and (3) only eight
(8) discrete segments of a Bank's Ratable Loan bearing interest at a LIBOR
Interest Rate for a designated Interest Period pursuant to a particular
Election, Conversion or Continuation, may be outstanding at any one time (each
such segment of each Bank's Ratable Loan corresponding to a proportionate
segment of each of the other Banks' Ratable Loans).

               Upon notice to Administrative Agent as provided in Section 2.13,
Borrower may Continue any LIBOR Loan on the last day of the Interest Period of
the same or different duration in accordance with the limitations provided
above.

                                       22
<PAGE>   24

               SECTION 2.06. Interest. Borrower shall pay interest to
Administrative Agent for the account of the applicable Bank on the outstanding
and unpaid principal amount of the Loans, at a rate per annum as follows: (1)
for Base Rate Loans at a rate equal to the Base Rate plus the Applicable Margin;
(2) for LIBOR Loans at a rate equal to the applicable LIBOR Interest Rate plus
the Applicable Margin; and (3) for Bid Rate Loans at a rate equal to the
applicable LIBOR Bid Rate. Any principal amount not paid when due (when
scheduled, at acceleration or otherwise) shall bear interest thereafter, payable
on demand, at the Default Rate.

               The interest rate on Base Rate Loans shall change when the Base
Rate changes. Interest on Base Rate Loans, LIBOR Loans and Bid Rate Loans shall
not exceed the maximum amount permitted under applicable law. Interest shall be
calculated for the actual number of days elapsed on the basis of, in the case of
Base Rate Loans, LIBOR Loans and Bid Rate Loans, three hundred sixty (360) days.

               Accrued interest shall be due and payable in arrears, (x) in the
case of both Base Rate Loans and LIBOR Loans, on the first Banking Day of each
calendar month and (y) in the case of Bid Rate Loans, at the expiration of the
Interest Period applicable thereto; provided, however, that interest accruing at
the Default Rate shall be due and payable on demand.

               SECTION 2.07. Fees. Borrower shall, during the term of the Loans
commencing as of the Closing Date, pay to Administrative Agent for the account
of each Bank a commitment fee computed (1) during periods when Borrower's Credit
Rating is below BBB- by S&P or below Baa3 by Moody's or unrated, on the daily
unused Loan Commitment of such Bank and (2) during periods when Borrower's
Credit Rating is BBB- or higher by S&P and Baa3 or higher by Moody's, on the
daily Loan Commitment of such Bank, in either such case at a rate per annum
equal to the daily Commitment Fee Rate, calculated on the basis of a year of
three hundred sixty (360) days for the actual number of days elapsed. The
accrued commitment fee shall be due and payable in arrears on the first day of
October, January, April and July of each year, commencing on the first such date
after the Closing Date, and upon the Maturity Date (as the case may be
accelerated) or earlier termination of the Loan Commitments.

               SECTION 2.08. Notes. The Ratable Loan made by each Bank under
this Agreement shall be evidenced by, and repaid with interest in accordance
with, a promissory note of Borrower in the form of EXHIBIT B duly completed and
executed by Borrower, in the principal amount equal to such Bank's Loan
Commitment, payable to such Bank for the account of its Applicable Lending
Office (each such note, as the same may hereafter be amended, modified,
extended, severed, assigned, substituted, renewed or restated from time to time,
including any substitute note pursuant to Section 3.07 or 12.05, a "Ratable Loan
Note"). The Bid Rate Loans of the Banks shall be evidenced by a single global
promissory note of Borrower in the form of EXHIBIT C, duly completed and
executed by Borrower, in the principal amount of Five Hundred Million Dollars
($500,000,000), payable to Administrative Agent for the account of the
respective Banks making Bid Rate Loans (such note, as the same may hereafter be
amended, modified, extended, severed, assigned, substituted, renewed or restated
from time to time, the "Bid Rate Loan Note"). A particular Bank's Ratable Loan
Note, together with its interest, if any, in the Bid Rate Loan Note, are
referred to collectively in this Agreement as such Bank's "Note"; all such
Ratable Loan Notes and interests are referred to collectively in this

                                       23
<PAGE>   25

Agreement as the "Notes". The Ratable Loan Notes shall mature, and all
outstanding principal and accrued interest and other sums thereunder shall be
paid in full, on the Maturity Date, as the same may be accelerated. The
outstanding principal amount of each Bid Rate Loan evidenced by the Bid Rate
Loan Note, and all accrued interest and other sums with respect thereto, shall
become due and payable to the Bank making such Bid Rate Loan at the earlier of
the expiration of the Interest Period applicable thereto or the Maturity Date,
as the same may be accelerated.

               Each Bank is hereby authorized by Borrower to endorse on the
schedule attached to the Ratable Loan Note held by it, the amount of each
advance, and each payment of principal received by such Bank for the account of
its Applicable Lending Office(s) on account of its Ratable Loan, which
endorsement shall, in the absence of manifest error, be conclusive as to the
outstanding balance of the Ratable Loan made by such Bank. Administrative Agent
is hereby authorized by Borrower to endorse on the schedule attached to the Bid
Rate Loan Note the amount of each Bid Rate Loan, the name of the Bank making the
same, the date of the advance thereof, the interest rate applicable thereto and
the expiration of the Interest Period applicable thereto (i.e., the maturity
date thereof). The failure by Administrative Agent or any Bank to make such
notations with respect to the Loans or each advance or payment shall not limit
or otherwise affect the obligations of Borrower under this Agreement or the
Notes.

               SECTION 2.09. Prepayments. Without prepayment premium or penalty
but subject to Section 3.05, Borrower may, upon at least one (1) Banking Day's
notice to Administrative Agent in the case of the Base Rate Loans, and at least
three (3) Banking Days' notice to Administrative Agent in the case of LIBOR
Loans, prepay the Ratable Loans in whole or, with respect to Base Rate Loans
only, in part, provided that (1) any partial prepayment under this Section shall
be in integral multiples of One Million Dollars ($1,000,000); and (2) each
prepayment under this Section shall include, at Administrative Agent's option,
all interest accrued on the amount of principal prepaid to (but excluding) the
date of prepayment.

               SECTION 2.10. Method of Payment. Borrower shall make each payment
under this Agreement and under the Notes not later than 11:00 a.m. (New York
time) on the date when due in Dollars to Administrative Agent at Administrative
Agent's Office in immediately available funds. Administrative Agent will
thereafter, on the day of its receipt of each such payment, cause to be
distributed to each Bank (1) such Bank's appropriate share (based upon the
respective outstanding principal amounts and interest due under the Notes of the
Banks) of the payments of principal and interest in like funds for the account
of such Bank's Applicable Lending Office; and (2) fees payable to such Bank in
accordance with the terms of this Agreement. Borrower hereby authorizes
Administrative Agent and the Banks, if and to the extent payment by Borrower is
not made when due under this Agreement or under the Notes, to charge from time
to time against any account Borrower maintains with Administrative Agent or any
Bank any amount so due to Administrative Agent and/or the Banks.

               Except to the extent provided in this Agreement, whenever any
payment to be made under this Agreement or under the Notes is due on any day
other than a Banking Day, such payment shall be made on the next succeeding
Banking Day, and such extension of time shall in such case be included in the
computation of the payment of interest and other fees, as the case may be.

               SECTION 2.11. Elections, Conversions or Continuation of Loans.
Subject to the provisions of Article III and Sections 2.05 and 2.12, Borrower
shall have the right to Elect to have all or a portion of any advance of the
Ratable Loans be LIBOR Loans, to Convert Base Rate Loans into LIBOR Loans, to
Convert LIBOR Loans into Base Rate Loans, or to Continue LIBOR Loans as LIBOR
Loans, at any time or from time to time, provided that: (1) Borrower shall give
Administrative Agent notice of each such Election, Conversion or Continuation as
provided in Section 2.13; and (2) a LIBOR Loan may be Continued only on the last
day of the applicable Interest Period for such LIBOR Loan. Except as otherwise
provided in this Agreement, each Election, Continuation and Conversion shall be
applicable to each Bank's Ratable Loan in accordance with its Pro Rata Share.

               SECTION 2.12. Minimum Amounts. With respect to the Ratable Loans
as a whole, each Election and each Conversion shall be in an amount at least
equal to Three Million Dollars ($3,000,000) and in integral multiples of One
Hundred Thousand Dollars ($100,000).

               SECTION 2.13. Certain Notices Regarding Elections, Conversions
and Continuations of Loans. Notices by Borrower to Administrative Agent of
Elections, Conversions and Continuations of LIBOR Loans shall be irrevocable and
shall be effective only if received by Administrative Agent not later than 10:00
a.m. (New York time) on the number of Banking Days prior to the date of the
relevant Election, Conversion or Continuation specified below:

                                  Notice                                 Banking Days Prior

     Elections of, Conversions into or Continuations as LIBOR Loans          three (3)
     </TABLE>

Promptly following its receipt of any such notice, Administrative Agent shall so
advise the Banks either by telephone or by facsimile. Each such notice of
Election shall specify the portion of the amount of the advance that is to be
LIBOR Loans (subject to Section 2.12) and the duration of the Interest Period
applicable thereto (subject to Section 2.05); each such notice of Conversion
shall specify the LIBOR Loans or Base Rate Loans to be Converted; and each such
notice of Conversion or Continuation shall specify the date of Conversion or
Continuation (which shall be a Banking Day), the amount thereof (subject to
Section 2.12) and the duration of the Interest Period applicable thereto
(subject to Section 2.05). In the event that Borrower fails to Elect to have any
portion of an advance of the Ratable Loans be LIBOR Loans, the entire amount of
such advance shall constitute Base Rate Loans. In the event that Borrower fails
to Continue LIBOR Loans within the time period and as otherwise provided in this
Section, such LIBOR Loans will be automatically Converted into Base Rate Loans
on the last day of the then current applicable Interest Period for such LIBOR
Loans.

               SECTION 2.14. Late Payment Premium. Borrower shall pay to
Administrative Agent for the account of the Banks a late payment premium in the
amount of 4% of any

                                       25
<PAGE>   27

payments of principal or interest under the Loans made more than ten (10) days
after the due date thereof, which shall be due with any such late payment.

               SECTION 2.15. Changes of Commitments. (a) At any time, Borrower
shall have the right, without premium or penalty, to terminate any unused Loan
Commitments existing as of the date of such termination, in whole or in part,
from time to time, provided that: (1) Borrower shall give notice of each such
termination to Administrative Agent (which shall promptly notify each of the
Banks) no later than 10:00 a.m. (New York time) on the date which is fifteen
(15) Banking Days prior to the effectiveness of such termination; (2) the Loan
Commitments of each of the Banks must be terminated ratably and simultaneously
with those of the other Banks; and (3) each partial termination of the Loan
Commitments as a whole (and corresponding reduction of the Total Loan
Commitment) shall be in an integral multiple of One Million Dollars
($1,000,000).

               (b) The Loan Commitments, to the extent terminated, may not be
reinstated.

               SECTION 2.16. Letters of Credit. (a) Borrower, by notice to
Administrative Agent, may request, in lieu of advances of proceeds of the
Ratable Loans, that Administrative Agent issue unconditional, irrevocable
standby letters of credit (each, a "Letter of Credit") for the account of
Borrower, payable by sight drafts, for such beneficiaries and with such other
terms as Borrower shall specify. Promptly upon issuance of a Letter of Credit,
Administrative Agent shall notify each of the Banks by telephone or by
facsimile.

               (b) The amount of any such Letter of Credit shall be limited to
the lesser of (1) Two Hundred Fifty Million Dollars ($250,000,000) less the
amount of all other Letters of Credit then issued and outstanding or (2) the
Available Total Loan Commitment, it being understood that the amount of each
Letter of Credit issued and outstanding shall effect a reduction, by an equal
amount, of the Available Total Loan Commitment as provided in Section 2.01(b)
(such reduction to be allocated to each Bank's Loan Commitment ratably in
accordance with the Banks' respective Pro Rata Shares).

               (c) The amount of each Letter of Credit shall be further subject
to the conditions and limitations applicable to amounts of advances set forth in
Section 2.03 and the procedures for the issuance of each Letter of Credit shall
be the same as the procedures applicable to the making of advances as set forth
in the first sentence of Section 2.04.

               (d) Administrative Agent's issuance of each Letter of Credit
shall be subject to Borrower's satisfaction of all conditions precedent to its
entitlement to an advance of proceeds of the Loans.

               (e) Each Letter of Credit shall expire no later than the earlier
of (x) one (1) month prior to the Maturity Date or (y) one (1) year after the
date of its issuance.

               (f) In connection with, and as a further condition to the
issuance of, each Letter of Credit, Borrower shall execute and deliver to
Administrative Agent an application for

                                       26
<PAGE>   28

the Letter of Credit on Administrative Agent's standard form therefor, together
with such other documents, opinions and assurances as Administrative Agent shall
reasonably require.

               (g) In connection with each Letter of Credit, Borrower hereby
covenants to pay to Administrative Agent the following fees, each payable
quarterly in arrears (on the first Banking Day of each calendar quarter
following the issuance of the Letter of Credit): (i) a fee, payable to
Administrative Agent for the account of the Banks, computed daily on the amount
of the Letter of Credit issued and outstanding at a rate per annum equal to the
"Banks' L/C Fee Rate" (as hereinafter defined) and (ii) a fee, payable to
Administrative Agent for its own account, computed daily on the amount of the
Letter of Credit issued and outstanding at a rate per annum of 0.125%. For
purposes of this Agreement, the "Banks' L/C Fee Rate" shall mean, at any time, a
rate per annum equal to the Applicable Margin for LIBOR Loans less 0.125% per
annum. It is understood and agreed that the last installment of the fees
provided for in this paragraph (g) with respect to any particular Letter of
Credit shall be due and payable on the first day of the calendar quarter
following the return, undrawn, or cancellation, of such Letter of Credit.

               (h) The parties hereto acknowledge and agree that, immediately
upon notice from Administrative Agent of any drawing under a Letter of Credit,
each Bank shall, notwithstanding the existence of a Default or Event of Default
or the non-satisfaction of any conditions precedent to the making of an advance
of the Loans, advance proceeds of its Ratable Loan, in an amount equal to its
Pro Rata Share of such drawing, which advance shall be made to Administrative
Agent to reimburse Administrative Agent, for its own account, for such drawing.
Each of the Banks further acknowledges that its obligation to fund its Pro Rata
Share of drawings under Letters of Credit as aforesaid shall survive the Banks'
termination of this Agreement or enforcement of remedies hereunder or under the
other Loan Documents. If any Ratable Loan cannot for any reason be made on the
date otherwise required above (including, without limitation, as a result of the
commencement of a proceeding under any applicable bankruptcy law with respect to
Borrower), then each of the Banks shall purchase (on the date such Ratable Loan
would otherwise have been made) from Administrative Agent a participation
interest in any unreimbursed drawing in an amount equal to its Pro Rata Share of
such unreimbursed drawing.

               (i) Borrower agrees, upon the occurrence of an Event of Default
and at the request of Administrative Agent, (x) to deposit with Administrative
Agent cash collateral in the amount of all the outstanding Letters of Credit,
which cash collateral is hereby pledged and shall be held by Administrative
Agent in an account as security for Borrower's obligations in connection with
the Letters of Credit and (y) to execute and deliver to Administrative Agent
such documents as Administrative Agent requests to confirm and perfect the
assignment of such cash collateral and such account to Administrative Agent for
the benefit of the Banks.

               (j) Any letter of credit issued and currently outstanding under
the Prior Credit Agreement shall be deemed to be a Letter of Credit under this
Agreement as of the Closing Date.

                                  ARTICLE III

                       YIELD PROTECTION; ILLEGALITY; ETC.

               SECTION 3.01. Additional Costs. Borrower shall pay directly to
each Bank from time to time on demand such amounts as such Bank may reasonably
determine to be necessary to compensate it for any increased costs which such
Bank determines are attributable to its making or maintaining a LIBOR Loan or a
Bid Rate Loan, or its obligation to make or maintain a LIBOR Loan or a Bid Rate
Loan, or its obligation to Convert a Base Rate Loan to a LIBOR Loan hereunder,
or any reduction in any amount receivable by such Bank hereunder in respect of
its LIBOR Loan or Bid Rate Loan(s) or such obligations (such increases in costs
and reductions in amounts receivable being herein called "Additional Costs"), in
each case resulting from any Regulatory Change which:

               (1) changes the basis of taxation of any amounts payable to such
        Bank under this Agreement or the Notes in respect of any such LIBOR Loan
        or Bid Rate Loan (other than (i) changes in the rate of general
        corporate, franchise, branch profit, net income or other income tax
        imposed on such Bank or its Applicable Lending Office or (ii) a tax
        described in Section 10.13); or

               (2) (other than to the extent the LIBOR Reserve Requirement is
        taken into account in determining the LIBOR Rate at the commencement of
        the applicable Interest Period) imposes or modifies any reserve, special
        deposit, deposit insurance or assessment, minimum capital, capital ratio
        or similar requirements relating to any extensions of credit or other
        assets of, or any deposits with or other liabilities of, such Bank
        (including any LIBOR Loan or Bid Rate Loan or any deposits referred to
        in the definition of "LIBOR Interest Rate" in Section 1.01), or any
        commitment of such Bank (including such Bank's Loan Commitment
        hereunder); or

               (3) imposes any other condition (unrelated to the basis of
        taxation referred to in paragraph (1) above) affecting this Agreement or
        the Notes (or any of such extensions of credit or liabilities).

               Without limiting the effect of the provisions of the first
paragraph of this Section, in the event that, by reason of any Regulatory
Change, any Bank either (1) incurs Additional Costs based on or measured by the
excess above a specified level of the amount of a category of deposits or other
liabilities of such Bank which includes deposits by reference to which the LIBOR
Interest Rate is determined as provided in this Agreement or a category of
extensions of credit or other assets of such Bank which includes loans based on
the LIBOR Interest Rate or (2) becomes subject to restrictions on the amount of
such a category of liabilities or assets which it may hold, then, if such Bank
so elects by notice to Borrower (with a copy to Administrative Agent), the
obligation of such Bank to permit Elections of, to Continue, or to Convert Base
Rate Loans into, LIBOR Loans shall be suspended (in which case the provisions of
Section 3.04 shall be applicable) until such Regulatory Change ceases to be in
effect.

                                       28
<PAGE>   30

               Determinations and allocations by a Bank for purposes of this
Section of the effect of any Regulatory Change pursuant to the first or second
paragraph of this Section, on its costs or rate of return of making or
maintaining its Loan or portions thereof or on amounts receivable by it in
respect of its Loan or portions thereof, and the amounts required to compensate
such Bank under this Section, shall be included in a calculation of such amounts
given to Borrower and shall be conclusive absent manifest error.

               SECTION 3.02. Limitation on Types of Loans. Anything herein to
the contrary notwithstanding, if, on or prior to the determination of the LIBOR
Interest Rate for any Interest Period:

               (1) Administrative Agent reasonably determines (which
        determination shall be conclusive) that quotations of interest rates for
        the relevant deposits referred to in the definition of "LIBOR Interest
        Rate" in Section 1.01 are not being provided in the relevant amounts or
        for the relevant maturities for purposes of determining rates of
        interest for the LIBOR Loans or Bid Rate Loans as provided in this
        Agreement; or

               (2) a Bank reasonably determines (which determination shall be
        conclusive) and promptly notifies Administrative Agent that the relevant
        rates of interest referred to in the definition of "LIBOR Interest Rate"
        in Section 1.01 upon the basis of which the rate of interest for LIBOR
        Loans or Bid Rate Loans for such Interest Period is to be determined do
        not adequately cover the cost to such Bank of making or maintaining such
        LIBOR Loan or Bid Rate Loan for such Interest Period;

then Administrative Agent shall give Borrower prompt notice thereof, and so long
as such condition remains in effect, the Banks (or, in the case of the
circumstances described in clause (2) above, the affected Bank) shall be under
no obligation to permit Elections of LIBOR Loans, to Convert Base Rate Loans
into LIBOR Loans or to Continue LIBOR Loans and Borrower shall, on the last
day(s) of the then current Interest Period(s) for the affected outstanding LIBOR
Loans or Bid Rate Loans, either (x) prepay the affected LIBOR Loans or Bid Rate
Loans pursuant to Section 3.07 or (y) Convert the affected LIBOR Loans into Base
Rate Loans in accordance with Section 2.11 or convert the rate of interest under
the affected Bid Rate Loans to the rate applicable to Base Rate Loans by
following the same procedures as are applicable for Conversions into Base Rate
Loans set forth in Section 2.11.

               SECTION 3.03. Illegality. Notwithstanding any other provision of
this Agreement, in the event that it becomes unlawful for any Bank or its
Applicable Lending Office to honor its obligation to make or maintain a LIBOR
Loan or Bid Rate Loan hereunder, to allow Elections or Continuations of a LIBOR
Loan or to Convert a Base Rate Loan into a LIBOR Loan, then such Bank shall
promptly notify Administrative Agent and Borrower thereof and such Bank's
obligation to make or maintain a LIBOR Loan or Bid Rate Loan, or to permit
Elections of, to Continue, or to Convert its Base Rate Loan into, a LIBOR Loan
shall be suspended (in which case the provisions of Section 3.04 shall be
applicable) until such time as such Bank may again make and maintain a LIBOR
Loan or Bid Rate Loan.

                                       29
<PAGE>   31

               SECTION 3.04. Treatment of Affected Loans. If the obligations of
any Bank to make or maintain a LIBOR Loan or a Bid Rate Loan, or to permit an
Election of a LIBOR Loan, to Continue its LIBOR Loan, or to Convert its Base
Rate Loan into a LIBOR Loan, are suspended pursuant to Section 3.01 or 3.03
(each LIBOR Loan or Bid Rate Loan so affected being herein called an "Affected
Loan"), such Bank's Affected Loan shall be automatically Converted into a Base
Rate Loan (or, in the case of an Affected Loan that is a Bid Rate Loan, the
interest rate thereon shall be converted to the rate applicable to Base Rate
Loans) on the last day of the then current Interest Period for the Affected Loan
(or, in the case of a Conversion or conversion resulting from Section 3.01 or
3.03, on such earlier date as such Bank may specify to Borrower).

               To the extent that such Bank's Affected Loan has been so
Converted (or the interest rate thereon so converted), all payments and
prepayments of principal which would otherwise be applied to such Bank's
Affected Loan shall be applied instead to its Base Rate Loan (or to its Bid Rate
Loan bearing interest at the converted rate) and such Bank shall have no
obligation to Convert its Base Rate Loan into a LIBOR Loan.

               SECTION 3.05. Certain Compensation. Other than in connection with
a Conversion of an Affected Loan, Borrower shall pay to Administrative Agent for
the account of the applicable Bank, upon the request of such Bank through
Administrative Agent which request includes a calculation of the amount(s) due,
such amount or amounts as shall be sufficient (in the reasonable opinion of such
Bank) to compensate it for any loss, cost or expense which such Bank reasonably
determines is attributable to:

               (1) any payment or prepayment of a LIBOR Loan or Bid Rate Loan
        made by such Bank, or any Conversion of a LIBOR Loan (or conversion of
        the rate of interest on a Bid Rate Loan) made by such Bank, in any such
        case on a date other than the last day of an applicable Interest Period,
        whether by reason of acceleration or otherwise; or

               (2) any failure by Borrower for any reason to Convert a LIBOR
        Loan or a Base Rate Loan or to Continue a LIBOR Loan, as the case may
        be, to be Converted or Continued by such Bank on the date specified
        therefor in the relevant notice under Section 2.13; or

               (3) any failure by Borrower to borrow (or to qualify for a
        borrowing of) a LIBOR Loan or Bid Rate Loan which would otherwise be
        made hereunder on the date specified in the relevant Election notice
        under Section 2.13 or Bid Rate Quote acceptance under Section 2.02(e)
        given or submitted by Borrower; or

               (4) any failure by Borrower to prepay a LIBOR Loan or Bid Rate
        Loan on the date specified in a notice of prepayment.

               Without limiting the foregoing, such compensation shall include
an amount equal to the present value (using as the discount rate an interest
rate equal to the rate determined under (2) below) of the excess, if any, of (1)
the amount of interest (less the Applicable Margin) which otherwise would have
accrued on the principal amount so paid, prepaid, Converted or Continued

                                       30
<PAGE>   32

(or not Converted, Continued or borrowed) for the period from the date of such
payment, prepayment, Conversion or Continuation (or failure to Convert, Continue
or borrow) to the last day of the then current applicable Interest Period (or,
in the case of a failure to Convert, Continue or borrow, to the last day of the
applicable Interest Period which would have commenced on the date specified
therefor in the relevant notice) at the applicable rate of interest for the
LIBOR Loan or Bid Rate Loan provided for herein, over (2) the amount of interest
(as reasonably determined by such Bank) based upon the interest rate which such
Bank would have bid in the London interbank market for Dollar deposits, for
amounts comparable to such principal amount and maturities comparable to such
period. A determination of any Bank as to the amounts payable pursuant to this
Section shall be conclusive absent manifest error.

               SECTION 3.06. Capital Adequacy. If any Bank shall have determined
that, after the date hereof, the adoption of, or any change in, any applicable
law, rule or regulation regarding capital adequacy, 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 any request or directive regarding capital adequacy (whether or not
having the force of law) of any such Governmental Authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on capital of such Bank (or its Parent) as a consequence of such Bank's
obligations hereunder to a level below that which such Bank (or its Parent)
could have achieved but for such adoption, change, request or directive (taking
into consideration its policies with respect to capital adequacy) by an amount
deemed by such Bank to be material, then from time to time, within fifteen (15)
days after demand by such Bank (with a copy to Administrative Agent), Borrower
shall pay to such Bank such additional amount or amounts as will compensate such
Bank (or its Parent) for such reduction. A certificate of any Bank claiming
compensation under this Section, setting forth in reasonable detail the basis
therefor, shall be conclusive absent manifest error.

               SECTION 3.07. Substitution of Banks. If any Bank (an "Affected
Bank") (i) makes demand upon Borrower for (or if Borrower is otherwise required
to pay) Additional Costs pursuant to Section 3.01 or (ii) is unable to make or
maintain a LIBOR Loan or Bid Rate Loan as a result of a condition described in
Section 3.03 or clause (2) of Section 3.02, Borrower may, within ninety (90)
days of receipt of such demand or notice (or the occurrence of such other event
causing Borrower to be required to pay Additional Costs or causing Section 3.03
or clause (2) of Section 3.02 to be applicable), as the case may be, give
written notice (a "Replacement Notice") to Administrative Agent and to each Bank
of Borrower's intention either (x) to prepay in full the Affected Bank's Note
and to terminate the Affected Bank's entire Loan Commitment or (y) to replace
the Affected Bank with another financial institution (the "Replacement Bank")
designated in such Replacement Notice.

               In the event Borrower opts to give the notice provided for in
clause (x) above, and if the Affected Bank shall not agree within thirty (30)
days of its receipt thereof to waive the payment of the Additional Costs in
question or the effect of the circumstances described in Section 3.03 or clause
(2) of Section 3.02, then, so long as no Default or Event of Default shall
exist, Borrower may (notwithstanding the provisions of clause (2) of Section
2.15(a)) terminate the Affected Bank's entire Loan Commitment, provided that in
connection therewith it pays to the Affected Bank all outstanding principal and
accrued and unpaid interest under the Affected

                                       31
<PAGE>   33

Bank's Note, together with all other amounts, if any, due from Borrower to the
Affected Bank, including all amounts properly demanded and unreimbursed under
Sections 3.01 and 3.05.

               In the event Borrower opts to give the notice provided for in
clause (y) above, and if (i) Administrative Agent shall, within thirty (30) days
of its receipt of the Replacement Notice, notify Borrower and each Bank in
writing that the Replacement Bank is reasonably satisfactory to Administrative
Agent and (ii) the Affected Bank shall not, prior to the end of such thirty
(30)-day period, agree to waive the payment of the Additional Costs in question
or the effect of the circumstances described in Section 3.03 or clause (2) of
Section 3.02, then the Affected Bank shall, so long as no Default or Event of
Default shall exist, assign its Note and all of its rights and obligations under
this Agreement to the Replacement Bank, and the Replacement Bank shall assume
all of the Affected Bank's rights and obligations, pursuant to an agreement,
substantially in the form of an Assignment and Assumption Agreement, executed by
the Affected Bank and the Replacement Bank. In connection with such assignment
and assumption, the Replacement Bank shall pay to the Affected Bank an amount
equal to the outstanding principal amount under the Affected Bank's Note plus
all interest accrued thereon, plus all other amounts, if any (other than the
Additional Costs in question), then due and payable to the Affected Bank;
provided, however, that prior to or simultaneously with any such assignment and
assumption, Borrower shall have paid to such Affected Bank all amounts properly
demanded and unreimbursed under Sections 3.01 and 3.05. Upon the effective date
of such assignment and assumption, the Replacement Bank shall become a Bank
Party to this Agreement and shall have all the rights and obligations of a Bank
as set forth in such Assignment and Assumption Agreement, and the Affected Bank
shall be released from its obligations hereunder, and no further consent or
action by any party shall be required. Upon the consummation of any assignment
pursuant to this Section, a substitute Ratable Loan Note shall be issued to the
Replacement Bank by Borrower, in exchange for the return of the Affected Bank's
Ratable Loan Note. The obligations evidenced by such substitute note shall
constitute "Obligations" for all purposes of this Agreement and the other Loan
Documents. If the Replacement Bank is not incorporated under the laws of the
United States of America or a state thereof, it shall, prior to the first date
on which interest or fees are payable hereunder for its account, deliver to
Borrower and Administrative Agent certification as to exemption from deduction
or withholding of any United States federal income taxes in accordance with
Section 10.13. Each Replacement Bank shall be deemed to have made the
representations contained in, and shall be bound by the provisions of, Section
10.13.

               Borrower, Administrative Agent and the Banks shall execute such
modifications to the Loan Documents as shall be reasonably required in
connection with and to effectuate the foregoing.

               SECTION 5.01. Existence. Borrower is a limited partnership duly

principal place of business in the State of New Jersey, and is duly qualified as
a foreign limited partnership, properly licensed, in good standing and has all
requisite authority to conduct its business in each jurisdiction in which it
owns properties or conducts business except where the failure to be so qualified

of its Consolidated Businesses is duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization and has all
requisite authority to conduct its business in each jurisdiction in which it
owns property or conducts business, except where the failure to be so qualified
or to obtain such authority would not constitute a Material Adverse Change.

                                       35
<PAGE>   37

               SECTION 5.02. Corporate/Partnership Powers. The execution,
delivery and performance of this Agreement and the Loan Documents required to be
delivered by Borrower hereunder are within its partnership authority and the
corporate power of General Partner, have been duly authorized by all requisite
action, and are not in conflict with the terms of any organizational instruments
of such entity, or any instrument or agreement to which Borrower or General
Partner is a party or by which Borrower, General Partner or any of their
respective assets may be bound or affected.

               SECTION 5.03. Power of Officers. The officers of General Partner
executing the Loan Documents required to be delivered by it on its own behalf or
that of Borrower hereunder have been duly elected or appointed and were fully
authorized to execute the same at the time each such Loan Document was executed.

               SECTION 5.04. Power and Authority; No Conflicts; Compliance With
Laws. The execution and delivery of, and the performance of the obligations
required to be performed by Borrower and General Partner under, the Loan
Documents do not and will not (a) violate any provision of, or require any
filing, registration, consent or approval under, any Law (including, without
limitation, Regulation U), order, writ, judgment, injunction, decree,
determination or award presently in effect having applicability to either of
them, (b) result in a breach of or constitute a default under or require any
consent under any indenture or loan or credit agreement or any other agreement,
lease or instrument to which either of them may be a party or by which either of
them or their properties may be bound or affected except for consents which have
been obtained, (c) result in, or require, the creation or imposition of any
Lien, upon or with respect to any of its properties now owned or hereafter
acquired, or (d) cause either of them to be in default under any such Law,
order, writ, judgment, injunction, decree, determination or award or any such
indenture, agreement, lease or instrument; to the best of their knowledge,
Borrower and General Partner are in compliance with all Laws applicable to them
and their properties where the failure to be in compliance would cause a
Material Adverse Change to occur.

               SECTION 5.05. Legally Enforceable Agreements. Each Loan Document
is a legal, valid and binding obligation of Borrower and/or General Partner, as
the case may be, enforceable in accordance with its terms, except to the extent
that such enforcement may be limited by applicable bankruptcy, insolvency and
other similar laws affecting creditors' rights generally.

               SECTION 5.06. Litigation. Except as disclosed in General
Partner's SEC Reports existing as of the date hereof, there are no actions,
suits or proceedings pending or, to its knowledge, threatened against Borrower,
General Partner or any of their Affiliates before any court or arbitrator or any
Governmental Authority reasonably likely to have a material effect on Borrower's
ability to repay the Loans.

               SECTION 5.07. Good Title to Properties. Borrower and each of its
Affiliates have good, marketable and legal title to all of the properties and
assets each of them purports to own (including, without limitation, those
reflected in the December 31, 1999 financial statements referred to in Section
5.15) and only with exceptions which do not materially detract from the value of
such property or assets or the use thereof in Borrower's and such Affiliate's
business,

                                       36
<PAGE>   38

and except to the extent that any such properties and assets have been
encumbered or disposed of since the date of such financial statements without
violating any of the covenants contained in Article VII or elsewhere in this
Agreement. Borrower and its Material Affiliates enjoy peaceful and undisturbed
possession of all leased property necessary in any material respect in the
conduct of their respective businesses. All such leases are valid and subsisting
and are in full force and effect.

               SECTION 5.08. Taxes. Borrower and General Partner have filed all
tax returns (federal, state and local) required to be filed and have paid all
taxes, assessments and governmental charges and levies due and payable without
the imposition of a penalty, including interest and penalties, except to the
extent they are the subject of a Good Faith Contest.

               SECTION 5.09. ERISA. Borrower and General Partner are in
compliance in all material respects with all applicable provisions of ERISA.
Neither a Reportable Event nor a Prohibited Transaction has occurred with
respect to any Plan; no notice of intent to terminate a Plan has been filed nor
has any Plan been terminated within the past five (5) years; no circumstance
exists which constitutes grounds under Section 4042 of ERISA entitling the PBGC
to institute proceedings to terminate, or appoint a trustee to administer, a
Plan, nor has the PBGC instituted any such proceedings; Borrower, General
Partner and the ERISA Affiliates have not completely or partially withdrawn
under Section 4201 or 4204 of ERISA from a Multiemployer Plan; Borrower, General
Partner and the ERISA Affiliates have met the minimum funding requirements of
Section 412 of the Code and Section 302 of ERISA of each with respect to the
Plans of each and there is no Unfunded Current Liability with respect to any
Plan established or maintained by each; and Borrower, General Partner and the
ERISA Affiliates have not incurred any liability to the PBGC under ERISA (other
than for the payment of premiums under Section 4007 of ERISA). No part of the
funds to be used by Borrower in satisfaction of its obligations under this
Agreement constitute "plan assets" of any "employee benefit plan" within the
meaning of ERISA or of any "plan" within the meaning of Section 4975(e)(1) of
the Code, as interpreted by the Internal Revenue Service and the U.S. Department
of Labor in rules, regulations, releases or bulletins or as interpreted under
applicable case law.

               SECTION 5.10. No Default on Outstanding Judgments or Orders.
Borrower and General Partner have satisfied all judgments which are not being
appealed and are not in default with respect to any judgment, order, writ,
injunction, decree, rule or regulation of any court, arbitrator or federal,
state, municipal or other Governmental Authority, commission, board, bureau,
agency or instrumentality, domestic or foreign.

               SECTION 5.11. No Defaults on Other Agreements. Except as
disclosed to the Bank Parties in writing or as disclosed in General Partner's
SEC Reports, Borrower or General Partner, to the best of their knowledge, are
not a party to any indenture, loan or credit agreement or any lease or other
agreement or instrument or subject to any partnership, trust or other
restriction which is likely to result in a Material Adverse Change. To the best
of their knowledge, neither Borrower nor General Partner is in default in any
respect in the performance, observance or fulfillment of any of the obligations,
covenants or conditions contained in any agreement or instrument which is likely
to result in a Material Adverse Change.

                                       37
<PAGE>   39

               SECTION 5.12. Government Regulation. Neither Borrower nor General
Partner is subject to regulation under the Investment Company Act of 1940 or any
statute or regulation limiting any such Person's ability to incur indebtedness
for money borrowed as contemplated hereby.

               SECTION 5.13. Environmental Protection. To Borrower's knowledge,
except as disclosed in General Partner's SEC Reports existing as of the date
hereof, none of Borrower's or its Affiliates' properties contains any Hazardous
Materials that, under any Environmental Law currently in effect, (1) would
impose liability on Borrower or General Partner that is likely to result in a
Material Adverse Change, or (2) is likely to result in the imposition of a Lien
on any assets of Borrower, General Partner or any Material Affiliates that is
likely to result in a Material Adverse Change. To Borrower's knowledge, neither
it, General Partner nor any Material Affiliates are in violation of, or subject
to any existing, pending or threatened investigation or proceeding by any
Governmental Authority under any Environmental Law that is likely to result in a
Material Adverse Change.

               SECTION 5.14. Solvency. Borrower and General Partner are, and
upon consummation of the transactions contemplated by this Agreement, the other
Loan Documents and any other documents, instruments or agreements relating
thereto, will be, Solvent.

               SECTION 5.15. Financial Statements. The VRT Consolidated
Financial Statements most recently delivered to the Banks pursuant to the terms
of this Agreement are in all material respects complete and correct and fairly
present the financial condition and results of operations of the subjects
thereof as of the dates of and for the periods covered by such statements, all
in accordance with GAAP. There has been no Material Adverse Change since the
date of such most recently delivered VRT Consolidated Financial Statements.

               SECTION 5.16. Valid Existence of Affiliates. Each Material
Affiliate is an entity duly organized and existing in good standing under the
laws of the jurisdiction of its formation. As to each Material Affiliate, its
correct name, the jurisdiction of its formation, Borrower's direct or indirect
percentage of beneficial interest therein, and the type of business in which it
is primarily engaged, are set forth on EXHIBIT F. Borrower and each of its
Material Affiliates have the power to own their respective properties and to
carry on their respective businesses now being conducted. Each Material
Affiliate is duly qualified as a foreign corporation to do business and is in
good standing in every jurisdiction in which the nature of the respective
businesses conducted by it or its respective properties, owned or held under
lease, make such qualification necessary and where the failure to be so
qualified would have the effect of a Material Adverse Change.

               SECTION 5.17. Insurance. Borrower and each of its Affiliates has
in force paid insurance with financially sound and reputable insurance companies
or associations in such amounts and covering such risks as are usually carried
by companies engaged in the same or a similar business and similarly situated
and reasonably acceptable to Administrative Agent.

               SECTION 5.18. Accuracy of Information; Full Disclosure. Neither
this Agreement nor any documents, financial statements, reports, notices,
schedules, certificates,

                                       38
<PAGE>   40

statements or other writings furnished by or on behalf of Borrower to
Administrative Agent or any Bank in connection with the negotiation of this
Agreement or the consummation of the transactions contemplated hereby, or
required herein to be furnished by or on behalf of Borrower (other than
projections which are made by Borrower in good faith), contains any untrue or
misleading statement of a material fact or omits a material fact necessary to
make the statements herein or therein not misleading. There is no fact which
Borrower has not disclosed to Administrative Agent and the Banks in writing or
which is not included in General Partner's SEC Reports which materially affects
adversely or, so far as Borrower can now foresee, will materially affect
adversely the business or financial condition of Borrower or the ability of
Borrower to perform this Agreement and the other Loan Documents.

                                   ARTICLE VI

                              AFFIRMATIVE COVENANTS

               So long as any of the Notes shall remain unpaid or the Loan

shall each:

               SECTION 6.01. Maintenance of Existence. Preserve and maintain its
legal existence and, if applicable, good standing in the jurisdiction of
organization and, if applicable, qualify and remain qualified as a foreign
entity in each jurisdiction in which such qualification is required, except to
the extent that failure to so qualify is not likely to result in a Material
Adverse Change.

and keep in force, and cause each of its Material Affiliates to maintain and
keep in force, insurance with financially sound and reputable insurance
companies or associations in such amounts and covering such risks as are usually
carried by companies engaged in the same or a similar business and similarly
situated, which insurance may provide for reasonable deductibility from coverage
thereof.

               SECTION 6.04. Compliance with Laws; Payment of Taxes. Comply in
all material respects with all Laws applicable to it or to any of its properties
or any part thereof, such compliance to include, without limitation, paying
before the same become delinquent all taxes, assessments and governmental
charges imposed upon it or upon any of its property, except to the extent they
are the subject of a Good Faith Contest.

               SECTION 6.05. Right of Inspection. At any reasonable time and
from time to time upon reasonable notice, permit Administrative Agent or any
Bank or any agent or representative thereof (provided that, at Borrower's
request, Administrative Agent or such Bank,

                                       39
<PAGE>   41

accounts of Borrower with the independent accountants of Borrower.

material respects with all applicable Environmental Laws and immediately pay or
cause to be paid all costs and expenses incurred in connection with such

required for the satisfaction of the conditions of this Agreement.

               SECTION 6.08. Maintenance of Properties. Do all things reasonably

                   ADMINISTRATIVE AGENT; RELATIONS AMONG BANKS

               SECTION 10.01. Appointment, Powers and Immunities of
Administrative Agent. Each Bank hereby irrevocably appoints and authorizes
Administrative Agent to act as its agent hereunder and under any other Loan
Document with such powers as are specifically delegated to Administrative Agent
by the terms of this Agreement and any other Loan Document, together with such
other powers as are reasonably incidental thereto. Administrative Agent shall
have no duties or responsibilities except those expressly set forth in this
Agreement and any other Loan Document or required by law, and shall not by
reason of this Agreement be a fiduciary or trustee for any Bank except to the
extent that Administrative Agent acts as an agent with respect to the receipt or
payment of funds (nor shall Administrative Agent have any fiduciary duty to
Borrower nor shall any Bank have any fiduciary duty to Borrower or to any other
Bank). Administrative Agent shall not be responsible to the Banks for any
recitals, statements, representations or warranties made by Borrower or any
officer, partner or official of Borrower or any other Person contained in this
Agreement or any other Loan Document, or in any certificate or other document or
instrument referred to or provided for in, or received by any of them under,
this Agreement or any other Loan Document, or for the value, legality, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document or any other document or instrument referred to or
provided for herein or therein, for the perfection or priority of any Lien
securing the Obligations or for any failure by Borrower to perform any of its
obligations hereunder or thereunder. Administrative Agent may employ agents and
attorneys-in-fact and shall not be responsible, except as to money or securities
received by it or its authorized agents, for the negligence or misconduct of any
such agents or attorneys-in-fact selected by it with reasonable care. Neither
Administrative Agent nor any of its directors, officers, employees or agents
shall be liable or responsible for any action taken or omitted to be taken by it
or them hereunder or under any other Loan Document or in connection herewith or
therewith, except for its or their own gross negligence or willful misconduct.
Borrower shall pay any fee agreed to by Borrower and Administrative Agent with
respect to Administrative Agent's services hereunder. Notwithstanding anything
to the contrary contained in this Agreement, Administrative Agent agrees with
the Banks that Administrative Agent shall perform its obligations under this
Agreement in good faith according to the same standard of care as that
customarily exercised by it in administering its own revolving credit loans.

               SECTION 10.02. Reliance by Administrative Agent. Administrative
Agent shall be entitled to rely upon any certification, notice or other
communication (including any thereof by telephone, telex, telegram or cable)
believed by it to be genuine and correct and to have been signed or sent by or
on behalf of the proper Person or Persons, and upon advice and statements of
legal counsel, independent accountants and other experts selected by
Administrative Agent. Administrative Agent may deem and treat each Bank as the
holder of the Loan made by it for all purposes hereof and shall not be required
to deal with any Person who has acquired a participation in any Loan or
participation from a Bank. As to any matters not expressly provided for by this
Agreement or any other Loan Document, Administrative Agent shall in all cases be
fully protected in acting, or in refraining from acting, hereunder in accordance
with instructions signed by the Required Banks, and such instructions of the

                                       47
<PAGE>   49

Required Banks and any action taken or failure to act pursuant thereto shall be
binding on all of the Banks and any other holder of all or any portion of any
Loan or participation.

               SECTION 10.03. Defaults. Administrative Agent shall not be deemed
to have knowledge of the occurrence of a Default or Event of Default unless
Administrative Agent has received notice from a Bank or Borrower specifying such
Default or Event of Default and stating that such notice is a "Notice of
Default." In the event that Administrative Agent receives such a notice of the
occurrence of a Default or Event of Default, Administrative Agent shall give
prompt notice thereof to the Banks. Administrative Agent, following consultation
with the Banks, shall (subject to Section 10.07 and Section 12.02) take such
action with respect to such Default or Event of Default which is continuing as
shall be directed by the Required Banks; provided that, unless and until
Administrative Agent shall have received such directions, Administrative Agent
may take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable in the best interest of
the Banks; and provided further that Administrative Agent shall not send a
notice of Default, Event of Default or acceleration to Borrower without the
approval of the Required Banks. In no event shall Administrative Agent be
required to take any such action which it determines to be contrary to law.

               SECTION 10.04. Rights of Agent as a Bank. With respect to its
Loan Commitment and the Loan provided by it, each Agent in its capacity as a
Bank hereunder shall have the same rights and powers hereunder as any other Bank
and may exercise the same as though it were not acting as such Agent, and the
term any "Bank" or "Banks" shall include each Agent in its capacity as a Bank.
Each Agent and its Affiliates may (without having to account therefor to any
Bank) accept deposits from, lend money to (on a secured or unsecured basis), and
generally engage in any kind of banking, trust or other business with, Borrower
(and any Affiliates of Borrower) as if it were not acting as such Agent.

               SECTION 10.05. Indemnification of Agent. Each Bank agrees to
indemnify each Agent (to the extent not reimbursed under Section 12.04 or under
the applicable provisions of any other Loan Document, but without limiting the
obligations of Borrower under Section 12.04 or such provisions), for its Pro
Rata Share of any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind and
nature whatsoever which may be imposed on, incurred by or asserted against such
Agent in any way relating to or arising out of this Agreement, any other Loan
Document or any other documents contemplated by or referred to herein or the
transactions contemplated hereby or thereby (including, without limitation, the
costs and expenses which Borrower is obligated to pay under Section 12.04) or
under the applicable provisions of any other Loan Document or the enforcement of
any of the terms hereof or thereof or of any such other documents or
instruments; provided that no Bank shall be liable for (1) any of the foregoing
to the extent they arise from the gross negligence or willful misconduct of the
party to be indemnified, (2) any loss of principal or interest with respect to
such Agent's Loan or (3) any loss suffered by such Agent in connection with a
swap or other interest rate hedging arrangement entered into with Borrower.

               SECTION 10.06. Non-Reliance on Agent and Other Banks. Each Bank
agrees that it has, independently and without reliance on any Agent or any other
Bank, and based on

                                       48
<PAGE>   50

such documents and information as it has deemed appropriate, made its own credit
analysis of Borrower and the decision to enter into this Agreement and that it
will, independently and without reliance upon any Agent or any other Bank, and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own analysis and decisions in taking or not taking
action under this Agreement or any other Loan Document. Each Agent shall not be
required to keep itself informed as to the performance or observance by Borrower
of this Agreement or any other Loan Document or any other document referred to
or provided for herein or therein or to inspect the properties or books of
Borrower. Except for notices, reports and other documents and information
expressly required to be furnished to the Banks by any Agent hereunder, each
Agent shall not have any duty or responsibility to provide any Bank with any
credit or other information concerning the affairs, financial condition or
business of Borrower (or any Affiliate of Borrower) which may come into the
possession of such Agent or any of its Affiliates. Each Agent shall not be
required to file this Agreement, any other Loan Document or any document or
instrument referred to herein or therein for record, or give notice of this
Agreement, any other Loan Document or any document or instrument referred to
herein or therein, to anyone.

               SECTION 10.07. Failure of Administrative Agent to Act. Except for
action expressly required of Administrative Agent hereunder, Administrative
Agent shall in all cases be fully justified in failing or refusing to act
hereunder unless it shall have received further assurances (which may include
cash collateral) of the indemnification obligations of the Banks under Section
10.05 in respect of any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action.

               SECTION 10.08. Resignation or Removal of Administrative Agent.
Administrative Agent shall have the right to resign at any time. Administrative
Agent may be removed at any time with cause by the Required Banks, provided that
Borrower and the other Banks shall be promptly notified thereof. Upon any such
removal or resignation, the Required Banks shall have the right to appoint a
successor Administrative Agent which successor Administrative Agent, so long as
it is reasonably acceptable to the Required Banks, shall be that Bank then
having the greatest Loan Commitment. If no successor Administrative Agent shall
have been so appointed by the Required Banks and shall have accepted such
appointment within thirty (30) days after the Required Banks' removal of the
retiring Administrative Agent, then the retiring Administrative Agent may, on
behalf of the Banks, appoint a successor Administrative Agent, which shall be
one of the Banks. The Required Banks or the retiring Administrative Agent, as
the case may be, shall upon the appointment of a successor Administrative Agent
promptly so notify Borrower and the other Banks. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder. After any retiring Administrative
Agent's removal hereunder as Administrative Agent, the provisions of this
Article X shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as Administrative Agent.

               SECTION 10.09. Amendments Concerning Agency Function.
Notwithstanding anything to the contrary contained in this Agreement,
Administrative Agent shall not be bound by any waiver, amendment, supplement or
modification of this Agreement or any other Loan Document which affects its
duties, rights, and/or function hereunder or thereunder unless it shall have
given its prior written consent thereto.

               SECTION 10.10. Liability of Administrative Agent. Administrative
Agent shall not have any liabilities or responsibilities to Borrower on account
of the failure of any Bank to perform its obligations hereunder or to any Bank
on account of the failure of Borrower to perform its obligations hereunder or
under any other Loan Document.

               SECTION 10.11. Transfer of Agency Function. Without the consent
of Borrower or any Bank, Administrative Agent may at any time or from time to
time transfer its functions as Administrative Agent hereunder to any of its
offices wherever located in the United States, provided that Administrative
Agent shall promptly notify Borrower and the Banks thereof.

               SECTION 10.12. Non-Receipt of Funds by Administrative Agent.
Unless Administrative Agent shall have received notice from a Bank or Borrower
(either one as appropriate being the "Payor") prior to the date on which such
Bank is to make payment hereunder to Administrative Agent of the proceeds of a
Loan or Borrower is to make payment to Administrative Agent, as the case may be
(either such payment being a "Required Payment"), which notice shall be
effective upon receipt, that the Payor will not make the Required Payment in
full to Administrative Agent, Administrative Agent may assume that the Required
Payment has been made in full to Administrative Agent on such date, and
Administrative Agent in its sole discretion may, but shall not be obligated to,
in reliance upon such assumption, make the amount thereof available to the
intended recipient on such date. If and to the extent the Payor shall not have
in fact so made the Required Payment in full to Administrative Agent, the
recipient of such payment shall repay to Administrative Agent forthwith on
demand such amount made available to it together with interest thereon, for each
day from the date such amount was so made available by Administrative Agent
until the date Administrative Agent recovers such amount, at the customary rate
set by Administrative Agent for the correction of errors among Banks for three
(3) Banking Days and thereafter at the Base Rate.

               SECTION 10.13. Withholding Taxes. Each Bank represents at all
times during the term of this Agreement that it is entitled to receive any
payments to be made to it hereunder without the withholding of any tax and will
furnish to Administrative Agent and Borrower such forms, certifications,
statements and other documents as Administrative Agent or Borrower may request
from time to time to evidence such Bank's exemption from the withholding of any
tax imposed by any jurisdiction or to enable Administrative Agent or Borrower to
comply with any applicable Laws or regulations relating thereto. Without
limiting the effect of the foregoing, if any Bank is not created or organized
under the laws of the United States of America or any state thereof, such Bank
will furnish to Administrative Agent and Borrower Form W-8ECI or Form W-8BEN of
the United States Internal Revenue Service, or such other forms, certifications,
statements or documents, duly executed and completed by such Bank as evidence of
such Bank's complete exemption from the withholding of United States tax with
respect thereto.

                                       50
<PAGE>   52

Administrative Agent shall not be obligated to make any payments hereunder to
such Bank in respect of any Loan or participation or such Bank's Loan Commitment
or obligation to purchase participations until such Bank shall have furnished to
Administrative Agent and Borrower the requested form, certification, statement
or document.

               SECTION 10.14. Minimum Commitment by UBS. Subsequent to the
Closing Date, UBS hereby agrees to maintain a Loan Commitment in an amount no
less than Sixty Million Dollars ($60,000,000) for so long as (1) no Event of
Default exists and (2) UBS remains as Administrative Agent, and further agrees
to hold and not to participate or assign any of such amount other than an
assignment to a Federal Reserve Bank or to the Parent or a majority-owned
subsidiary of UBS.

               SECTION 10.15. Pro Rata Treatment. Except to the extent otherwise
provided, (1) each advance of proceeds of the Ratable Loans shall be made by the
Banks, (2) each reduction of the amount of the Total Loan Commitment under
Section 2.15 shall be applied to the Loan Commitments of the Banks and (3) each
payment of the commitment fee accruing under Section 2.07(a) shall be made for
the account of the Banks, ratably according to the amounts of their respective
Loan Commitments.

               SECTION 10.16. Sharing of Payments Among Banks. If a Bank shall
obtain payment of any principal of or interest on any Loan made by it through
the exercise of any right of setoff, banker's lien or counterclaim, or by any
other means (including direct payment), and such payment results in such Bank
receiving a greater payment than it would have been entitled to had such payment
been paid directly to Administrative Agent for disbursement to the Banks, then
such Bank shall promptly purchase for cash from the other Banks participations
in the Loans made by the other Banks in such amounts, and make such other
adjustments from time to time as shall be equitable to the end that all the
Banks shall share ratably the benefit of such payment. To such end the Banks
shall make appropriate adjustments among themselves (by the resale of
participations sold or otherwise) if such payment is rescinded or must otherwise
be restored. Borrower agrees that any Bank so purchasing a participation in the
Loans made by other Banks may exercise all rights of setoff, banker's lien,
counterclaim or similar rights with respect to such participation. Nothing
contained herein shall require any Bank to exercise any such right or shall
affect the right of any Bank to exercise, and retain the benefits of exercising,
any such right with respect to any other indebtedness of Borrower.

               SECTION 10.17. Possession of Documents. Each Bank shall keep
possession of its own Ratable Loan Note. Administrative Agent shall hold all the
other Loan Documents and related documents in its possession and maintain
separate records and accounts with respect thereto, and shall permit the Banks
and their representatives access at all reasonable times to inspect such Loan
Documents, related documents, records and accounts.

                                   ARTICLE XI

                              NATURE OF OBLIGATIONS

               SECTION 11.01. Absolute and Unconditional Obligations. Borrower
and General Partner acknowledge and agree that their obligations and liabilities
under this Agreement and under the other Loan Documents shall be absolute and
unconditional irrespective of: (1) any lack of validity or enforceability of any
of the Obligations, any Loan Documents, or any agreement or instrument relating
thereto; (2) any change in the time, manner or place of payment of, or in any
other term in respect of, all or any of the Obligations, or any other amendment
or waiver of or consent to any departure from any Loan Documents or any other
documents or instruments executed in connection with or related to the
Obligations; (3) any exchange or release of any collateral, if any, or of any
other Person from all or any of the Obligations; or (4) any other circumstances
which might otherwise constitute a defense available to, or a discharge of,
Borrower, General Partner or any other Person in respect of the Obligations.

               The obligations and liabilities of Borrower and General Partner
under this Agreement and the other Loan Documents shall not be conditioned or
contingent upon the pursuit by any Bank or any other Person at any time of any
right or remedy against Borrower, General Partner or any other Person which may
be or become liable in respect of all or any part of the Obligations or against
any collateral or security or guarantee therefor or right of setoff with respect
thereto.

               SECTION 11.02. Non-Recourse to VRT Principals. This Agreement and
the obligations hereunder and under the other Loan Documents are fully recourse
to Borrower and General Partner. Notwithstanding anything to the contrary
contained in this Agreement, in any of the other Loan Documents, or in any other
instruments, certificates, documents or agreements executed in connection with
the Loans (all of the foregoing, for purposes of this Section, hereinafter
referred to, individually and collectively, as the "Relevant Documents"), no
recourse under or upon any Obligation, representation, warranty, promise or
other matter whatsoever shall be had against any of the VRT Principals, and each
Bank expressly waives and releases, on behalf of itself and its successors and
assigns, all right to assert any liability whatsoever under or with respect to
the Relevant Documents against, or to satisfy any claim or obligation arising
thereunder against, any of the VRT Principals or out of any assets of the VRT
Principals, provided, however, that nothing in this Section shall be deemed to:
(1) release Borrower or General Partner from any personal liability pursuant to,
or from any of its respective obligations under, the Relevant Documents, or from
personal liability for its fraudulent actions or fraudulent omissions; (2)
release any VRT Principals from personal liability for its or his own fraudulent
actions or fraudulent omissions; (3) constitute a waiver of any obligation
evidenced or secured by, or contained in, the Relevant Documents or affect in
any way the validity or enforceability of the Relevant Documents; or (4) limit
the right of Administrative Agent and/or the Banks to proceed against or realize
upon any collateral hereafter given for the Loans or any and all of the assets
of Borrower or General Partner (notwithstanding the fact that the VRT Principals
have an ownership interest in Borrower or General Partner and, thereby, an
interest in the assets of Borrower or General Partner) or to name Borrower or
General Partner (or, to the extent that the same are required by applicable law
or are determined by a court to be necessary parties in

                                       52
<PAGE>   54

connection with an action or suit against Borrower, General Partner or any
collateral hereafter given for the Loans, any of the VRT Principals) as a party
defendant in, and to enforce against any collateral hereafter given for the
Loans and/or assets of Borrower or General Partner any judgment obtained by
Administrative Agent and/or the Banks with respect to, any action or suit under
the Relevant Documents so long as no judgment shall be taken (except to the
extent taking a judgment is required by applicable law or determined by a court
to be necessary to preserve Administrative Agent's and/or Banks' rights against
any collateral hereafter given for the Loans or Borrower or General Partner, but
not otherwise) or shall be enforced against the VRT Principals or their assets.

                                  ARTICLE XII

                                  MISCELLANEOUS

               SECTION 12.01. Binding Effect of Request for Advance. Borrower
agrees that, by its acceptance of any advance of proceeds of the Loans under
this Agreement or the issuance of any Letter of Credit, it shall be bound in all
respects by the request for advance or Letter of Credit submitted on its behalf
in connection therewith with the same force and effect as if Borrower had itself
executed and submitted the request for advance or Letter of Credit and whether
or not the request for advance is executed and/or submitted by an authorized
person.

               SECTION 12.02. Amendments and Waivers. No amendment or material
waiver of any provision of this Agreement or any other Loan Document nor consent
to any material departure by Borrower therefrom, shall in any event be effective
unless the same shall be in writing and signed by the Required Banks and, solely
for purposes of its acknowledgment thereof, Administrative Agent, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given, provided, however, that no amendment, waiver
or consent shall, unless in writing and signed by all the Banks do any of the
following: (1) reduce the principal of, or interest on, the Notes or any fees
due hereunder or any other amount due hereunder or under any other Loan
Document; (2) postpone any date fixed for any payment of principal of, or
interest on, the Notes or any fees due hereunder or under any other Loan
Document; (3) change the definition of Required Banks; (4) amend this Section
12.02 or any other provision requiring the consent of all the Banks; (5) waive
any default in payment under paragraph (1) of Section 9.01 or any default under
paragraph (5) of Section 9.01; (6) increase the Total Loan Commitment; or (7)
release the Guaranty. Any advance of proceeds of the Loans made prior to or
without the fulfillment by Borrower of all of the conditions precedent thereto,
whether or not known to Administrative Agent and the Banks, shall not constitute
a waiver of the requirement that all conditions, including the non-performed
conditions, shall be required with respect to all future advances. No failure on
the part of Administrative Agent or any Bank to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof or preclude
any other or further exercise thereof or the exercise of any other right. The
remedies herein provided are cumulative and not exclusive of any remedies
provided by law. All communications from Administrative Agent to the Banks
requesting the Banks' determination, consent, approval or disapproval (i) shall
be given in the form of a written notice to each Bank, (ii) shall be accompanied
by a description of the matter or thing as to which such determination,

                                       53
<PAGE>   55

approval, consent or disapproval is requested and (iii) shall include
Administrative Agent's recommended course of action or determination in respect
thereof. Each Bank shall reply promptly, but in any event within fifteen (15)
Banking Days (or five (5) Banking Days with respect to any decision to
accelerate or stop acceleration of the Loan) after receipt of the request
therefor by Administrative Agent (the "Bank Reply Period"). Unless a Bank shall
give written notice to Administrative Agent that it objects to the
recommendation or determination of Administrative Agent (together with a written
explanation of the reasons behind such objection) within the Bank Reply Period,
such Bank shall be deemed to have approved or consented to such recommendation
or determination.

               SECTION 12.03. Usury. Anything herein to the contrary
notwithstanding, the obligations of Borrower under this Agreement and the Notes
shall be subject to the limitation that payments of interest shall not be
required to the extent that receipt thereof would be contrary to provisions of
law applicable to a Bank limiting rates of interest which may be charged or
collected by such Bank.

               SECTION 12.04. Expenses; Indemnification. Borrower agrees to
reimburse Administrative Agent on demand for all costs, expenses, and charges
(including, without limitation, all reasonable fees and charges of engineers,
appraisers and external legal counsel) incurred by Administrative Agent in
connection with the Loans and to reimburse each of the Banks for reasonable
legal costs, expenses and charges incurred by each of the Banks in connection
with the performance or enforcement of this Agreement, the Notes, or any other
Loan Documents; provided, however, that Borrower is not responsible for costs,
expenses and charges incurred by the Bank Parties in connection with the
administration or syndication of the Loans (other than any administration fee
payable to Administrative Agent). Borrower agrees to indemnify Administrative
Agent and each Bank and their respective directors, officers, employees and
agents from, and hold each of them harmless against, any and all losses,
liabilities, claims, damages or expenses incurred by any of them arising out of
or by reason of (x) any claims by brokers due to acts or omissions by Borrower,
or (y) any investigation or litigation or other proceedings (including any
threatened investigation or litigation or other proceedings) relating to any
actual or proposed use by Borrower of the proceeds of the Loans, including
without limitation, the reasonable fees and disbursements of counsel incurred in
connection with any such investigation or litigation or other proceedings (but
excluding any such losses, liabilities, claims, damages or expenses incurred by
reason of the gross negligence or willful misconduct of the Person to be
indemnified).

               The obligations of Borrower under this Section shall survive the
repayment of all amounts due under or in connection with any of the Loan
Documents and the termination of the Loan Commitments.

               SECTION 12.05. Assignment; Participation. This Agreement shall be
binding upon, and shall inure to the benefit of, Borrower, Administrative Agent,
the Banks and their respective successors and permitted assigns. Borrower may
not assign or transfer its rights or obligations hereunder.

                                       54
<PAGE>   56

               Any Bank or its Designated Lender may at any time grant to one or
more banks or other institutions or entities (each a "Participant")
participating interests in its Loan and/or Loan Commitment (the
"Participations"). In the event of any such grant by a Bank of a participating
interest to a Participant, whether or not Borrower or Administrative Agent was
given notice, such Bank shall remain responsible for the performance of its
obligations hereunder, and Borrower and Administrative Agent shall continue to
deal solely and directly with such Bank in connection with such Bank's rights
and obligations hereunder. Any agreement pursuant to which any Bank may grant
such a participating interest shall provide that such Bank shall retain the sole
right and responsibility to enforce the obligations of Borrower hereunder and
under any other Loan Document including, without limitation, the right to
approve any amendment, modification or waiver of any provision of this Agreement
or any other Loan Document; provided that such participation agreement may
provide that such Bank will not agree to any modification, amendment or waiver
of this Agreement described in clauses (1) through (7) of Section 12.02 without
the consent of the Participant.

               Subject to the provisions of Section 10.14, any Bank may at any
time assign to any bank or other institution with the acknowledgment of
Administrative Agent and the consent of UBS and, provided there exists no Event
of Default, of Borrower, which consents shall not be unreasonably withheld or
delayed (such assignee, a "Consented Assignee"), or to one or more banks or
other institutions which are majority owned subsidiaries of a Bank or to the
Parent of a Bank (each Consented Assignee or subsidiary bank or institution, an
"Assignee") all, or a proportionate part of all, of its rights and obligations
under this Agreement and its Note, and such Assignee shall assume rights and
obligations, pursuant to an Assignment and Assumption Agreement executed by such
Assignee and the assigning Bank, provided that, in each case, after giving
effect to such assignment the Assignee's Loan Commitment and, in the case of a
partial assignment, the assigning Bank's Loan Commitment, each will be equal to
or greater than Fifteen Million Dollars ($15,000,000). Upon (i) execution and
delivery of such instrument, (ii) payment by such Assignee to the Bank of an
amount equal to the purchase price agreed between the Bank and such Assignee and
(iii) payment by such Assignee to Administrative Agent of a fee, for
Administrative Agent's own account, in the amount of Two Thousand Five Hundred
Dollars ($2,500), such Assignee shall be a Bank party to this Agreement and
shall have all the rights and obligations of a Bank as set forth in such
Assignment and Assumption Agreement, and the assigning Bank 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 paragraph, substitute Ratable Loan Notes shall be
issued to the assigning Bank (in the case of a partial assignment) and Assignee
by Borrower, in exchange for the return of the original Ratable Loan Note of the
assigning Bank. The obligations evidenced by such substitute notes shall
constitute "Obligations" for all purposes of this Agreement and the other Loan
Documents. If the Assignee is not incorporated under the laws of the United
States of America or a state thereof, it shall, prior to the first date on which
interest or fees are payable hereunder for its account, deliver to Borrower and
Administrative Agent certification as to exemption from deduction or withholding
of any United States federal income taxes in accordance with Section 10.13. Each
Assignee shall be deemed to have made the representations contained in, and
shall be bound by the provisions of, Section 10.13.

                                       55
<PAGE>   57

               Any Bank may at any time assign all or any portion of its rights
under this Agreement and its Note to a Federal Reserve Bank. No such assignment
shall release the transferor Bank from its obligations hereunder.

               Borrower recognizes that in connection with a Bank's selling of
Participations or making of assignments, any or all documentation, financial
statements and other data, or copies thereof, relevant to Borrower or the Loans
may be exhibited to and retained by any such Participant or assignee or
prospective Participant or assignee. In connection with a Bank's delivery of any
financial statements and appraisals to any such Participant or assignee or
prospective Participant or assignee, such Bank shall also indicate that the same
are delivered on a confidential basis. Borrower agrees to provide all assistance
reasonably requested by a Bank to enable such Bank to sell Participations or
make assignments of its Loan and Loan Commitment as permitted by this Section
12.05. Each Bank agrees to provide Borrower with notice of all Participations
sold by such Bank.

               SECTION 12.06. Documentation Satisfactory. All documentation
required from or to be submitted on behalf of Borrower in connection with this
Agreement and the documents relating hereto shall be subject to the prior
approval of, and be satisfactory in form and substance to, Administrative Agent,
its counsel and, where specifically provided herein, the Banks. In addition, the
persons or parties responsible for the execution and delivery of, and
signatories to, all of such documentation, shall be acceptable to, and subject
to the approval of, Administrative Agent and its counsel and the Banks.

               SECTION 12.07. Notices. Unless the party to be notified otherwise
notifies the other parties in writing as provided in this Section, and except as
otherwise provided in this Agreement, notices shall be given to Administrative
Agent by telephone, confirmed by writing, and to the Banks and to Borrower and
General Partner by ordinary mail or overnight courier or telecopy, receipt
confirmed, addressed to such party at its address on the signature page of this
Agreement. Notices shall be effective: (1) if by telephone, at the time of such
telephone conversation, (2) if given by mail, three (3) days after mailing; (3)
if given by overnight courier, upon receipt; and (4) if given by telecopy, upon
receipt.

               SECTION 12.08. Setoff. To the extent permitted or not expressly
prohibited by applicable law, Borrower and General Partner agree that, in
addition to (and without limitation of) any right of setoff, bankers' lien or
counterclaim a Bank may otherwise have, each Bank shall be entitled, at its
option, to offset balances (general or special, time or demand, provisional or
final) held by it for the account of Borrower or General Partner at any of such
Bank's offices, in Dollars or in any other currency, against any amount payable
by Borrower or General Partner to such Bank under this Agreement or such Bank's
Note, or any other Loan Document, which is not paid when due (regardless of
whether such balances are then due to Borrower or General Partner), in which
case it shall promptly notify Borrower, General Partner and Administrative Agent
thereof; provided that such Bank's failure to give such notice shall not affect
the validity thereof. Payments by Borrower or General Partner hereunder or under
the other Loan Documents shall be made without setoff or counterclaim.

                                       56
<PAGE>   58

               SECTION 12.09. Table of Contents; Headings. Any table of contents
and the headings and captions hereunder are for convenience only and shall not
affect the interpretation or construction of this Agreement.

               SECTION 12.10. Severability. The provisions of this Agreement are
intended to be severable. If for any reason any provision of this Agreement
shall be held invalid or unenforceable in whole or in part in any jurisdiction,
such provision shall, as to such jurisdiction, be ineffective to the extent of
such invalidity or unenforceability without in any manner affecting the validity
or enforceability thereof in any other jurisdiction or the remaining provisions
hereof in any jurisdiction.

               SECTION 12.11. Counterparts. This Agreement may be executed in
any number of counterparts, all of which taken together shall constitute one and
the same instrument, and any party hereto may execute this Agreement by signing
any such counterpart.

               SECTION 12.12. Integration. The Loan Documents set forth the
entire agreement among the parties hereto relating to the transactions
contemplated thereby (except with respect to agreements relating solely to
compensation, consideration and the coordinated syndication of the Loan) and
supersede any prior oral or written statements or agreements with respect to
such transactions.

               SECTION 12.13. Governing Law. This Agreement shall be governed
by, and interpreted and construed in accordance with, the laws of the State of
New York.

               SECTION 12.14. Waivers. To the extent permitted or not expressly
prohibited by applicable law, in connection with the obligations and liabilities
as aforesaid, Borrower and General Partner hereby waive: (1) promptness and
diligence; (2) notice of any actions taken by any Bank Party under this
Agreement, any other Loan Document or any other agreement or instrument relating
hereto or thereto except to the extent otherwise provided herein; (3) all other
notices, demands and protests, and all other formalities of every kind in
connection with the enforcement of the Obligations, the omission of or delay in
which, but for the provisions of this Section 12.14, might constitute grounds
for relieving Borrower or General Partner of their obligations hereunder; (4)
any requirement that any Bank Party protect, secure, perfect or insure any Lien
on any collateral or exhaust any right or take any action against Borrower,
General Partner or any other Person or any collateral; (5) any right or claim of
right to cause a marshalling of the assets of Borrower or General Partner; and
(6) all rights of subrogation or contribution, whether arising by contract or
operation of law (including, without limitation, any such right arising under
the Federal Bankruptcy Code) or otherwise by reason of payment by Borrower or
General Partner, either jointly or severally, pursuant to this Agreement or any
other Loan Document.

               SECTION 12.15. Jurisdiction; Immunities. Borrower, General
Partner, Administrative Agent and each Bank hereby irrevocably submit to the
jurisdiction of any New York State or United States Federal court sitting in New
York City over any action or proceeding arising out of or relating to this
Agreement, the Notes or any other Loan Document. Borrower, General Partner,
Administrative Agent, and each Bank irrevocably agree that all claims in

                                       57
<PAGE>   59

respect of such action or proceeding may be heard and determined in such New
York State or United States Federal court. Borrower, General Partner,
Administrative Agent, and each Bank irrevocably consent to the service of any
and all process in any such action or proceeding by the mailing of copies of
such process to Borrower, General Partner, Administrative Agent or each Bank, as
the case may be, at the addresses specified herein. Borrower, General Partner,
Administrative Agent and each Bank agree that a final judgment in any such
action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Borrower, General Partner, Administrative Agent and each Bank further waive any
objection to venue in the State of New York and any objection to an action or
proceeding in the State of New York on the basis of forum non conveniens.
Borrower, General Partner, Administrative Agent and each Bank agree that any
action or proceeding brought against Borrower, General Partner, Administrative
Agent or any Bank, as the case may be, shall be brought only in a New York State
court sitting in New York City or a United States Federal court sitting in New
York City, to the extent permitted or not expressly prohibited by applicable
law.

               Nothing in this Section shall affect the right of Borrower,
General Partner, Administrative Agent or any Bank to serve legal process in any
other manner permitted by law.

               To the extent that Borrower, General Partner, Administrative
Agent or any Bank have or hereafter may acquire any immunity from jurisdiction
of any court or from any legal process (whether from service or notice,
attachment prior to judgment, attachment in aid of execution, execution or
otherwise) with respect to itself or its property, Borrower, General Partner,
Administrative Agent and each Bank hereby irrevocably waive such immunity in
respect of its obligations under this Agreement, the Notes and any other Loan
Document.

               BORROWER, GENERAL PARTNER, ADMINISTRATIVE AGENT AND EACH BANK
WAIVE ANY RIGHT EACH SUCH PARTY MAY HAVE TO JURY TRIAL IN CONNECTION WITH ANY
SUIT, ACTION OR PROCEEDING BROUGHT WITH RESPECT TO THIS AGREEMENT, THE NOTES OR
THE LOAN. IN ADDITION, BORROWER AND GENERAL PARTNER HEREBY WAIVE, IN CONNECTION
WITH ANY SUIT, ACTION OR PROCEEDING BROUGHT BY ADMINISTRATIVE AGENT OR THE BANKS
WITH RESPECT TO THE NOTES, ANY RIGHT BORROWER OR GENERAL PARTNER MAY HAVE TO (1)
TO THE EXTENT PERMITTED OR NOT EXPRESSLY PROHIBITED BY APPLICABLE LAW, INTERPOSE
ANY COUNTERCLAIM THEREIN (OTHER THAN A COUNTERCLAIM THAT IF NOT BROUGHT IN THE
SUIT, ACTION OR PROCEEDING BROUGHT BY ADMINISTRATIVE AGENT OR THE BANKS COULD
NOT BE BROUGHT IN A SEPARATE SUIT, ACTION OR PROCEEDING OR WOULD BE SUBJECT TO
DISMISSAL OR SIMILAR DISPOSITION FOR FAILURE TO HAVE BEEN ASSERTED IN SUCH SUIT,
ACTION OR PROCEEDING BROUGHT BY ADMINISTRATIVE AGENT OR THE BANKS) OR (2) TO THE
EXTENT PERMITTED OR NOT EXPRESSLY PROHIBITED BY APPLICABLE LAW, HAVE THE SAME
CONSOLIDATED WITH ANY OTHER OR SEPARATE SUIT, ACTION OR PROCEEDING. NOTHING
HEREIN CONTAINED SHALL PREVENT OR PROHIBIT BORROWER OR GENERAL PARTNER FROM
INSTITUTING OR MAINTAINING A SEPARATE ACTION

                                       58
<PAGE>   60

AGAINST ADMINISTRATIVE AGENT OR THE BANKS WITH RESPECT TO ANY ASSERTED CLAIM.

               SECTION 12.16. Designated Lender. Any Bank (other than a Bank
which is such solely because it is a Designated Lender) (each, a "Designating
Lender") may at any time designate one (1) Designated Lender to fund Bid Rate
Loans on behalf of such Designating Lender subject to the terms of this Section
and the provisions in Section 12.05 shall not apply to such designation. No Bank
may designate more than one (1) Designated Lender. The parties to each such
designation shall execute and deliver to Administrative Agent for its acceptance
a Designation Agreement. Upon such receipt of an appropriately completed
Designation Agreement executed by a Designating Lender and a designee
representing that it is a Designated Lender, Administrative Agent will accept
such Designation Agreement and give prompt notice thereto to Borrower,
whereupon, (i) from and after the "Effective Date" specified in the Designation
Agreement, the Designated Lender shall become a party to this Agreement with a
right to make Bid Rate Loans on behalf of its Designating Lender pursuant to
Section 2.02 after Borrower has accepted the Bid Rate Quote of the Designating
Lender and (ii) the Designated Lender shall not be required to make payments
with respect to any obligations in this Agreement except to the extent of excess
cash flow of such Designated Lender which is not otherwise required to repay
obligations of such Designated Lender which are then due and payable; provided,
however, that regardless of such designation and assumption by the Designated
Lender, the Designating Lender shall be and remain obligated to Borrower,
Administrative Agent and the Banks for each and every of the obligations of the
Designating Lender and its related Designated Lender with respect to this
Agreement, including, without limitation, any indemnification obligations under
Section 10.05. Each Designating Lender shall serve as the administrative agent
of its Designated Lender and shall on behalf of, and to the exclusion of, the
Designated Lender: (i) receive any and all payments made for the benefit of the
Designated Lender and (ii) give and receive all communications and notices and
take all actions hereunder, including, without limitation, votes, approvals,
waivers and consents under or relating to this Agreement and the other Loan
Documents. Any such notice, communication, vote, approval, waiver or consent
shall be signed by the Designating Lender as administrative agent for the
Designated Lender and shall not be signed by the Designated Lender on its own
behalf, but shall be binding on the Designated Lender to the same extent as if
actually signed by the Designated Lender. Borrower, Administrative Agent and the
Banks may rely thereon without any requirement that the Designated Lender sign
or acknowledge the same. No Designated Lender may assign or transfer all or any
portion of its interest hereunder or under any other Loan Document, other than
assignments to the Designating Lender which originally designated such
Designated Lender.

               SECTION 12.17. No Bankruptcy Proceedings. Each of Borrower, the
Banks and Administrative Agent hereby agrees that it will not institute against
any Designated Lender or join any other Person in instituting against any
Designated Lender any bankruptcy, reorganization, arrangement, insolvency or
liquidation proceeding under any federal or state bankruptcy or similar law, for
one (1) year and one (1) day after the payment in full of the latest maturing
commercial paper note issued by such Designated Lender.

               Re:    Revolving Credit Agreement dated as of the date hereof
                      (the "Loan Agreement"; capitalized terms not otherwise
                      defined herein shall have the meanings ascribed to such
                      terms in the Loan Agreement) among us, as Borrower, the
                      Banks named therein, and you, as Administrative Agent for
                      said Banks

Gentlemen:

               In connection with the captioned Loan Agreement, we hereby
designate any of the following persons to give to you instructions, including
notices required pursuant to the Loan Agreement, orally, by telephone or
teleprocess, or in writing:

                      Steven Roth
                      Michael Fascitelli
                      Joseph Macnow
                      Ross Morrison
                      Irwin Goldberg.

               Instructions may be honored on the oral, telephonic, teleprocess
or written instructions of anyone purporting to be any one of the above
designated persons even if the instructions are for the benefit of the person
delivering them. We will furnish you with confirmation of each such instruction
either by telex (whether tested or untested) or in writing signed by any person
designated above (including any telecopy which appears to bear the signature of
any person designated above) on the same day that the instruction is provided to
you but your responsibility with respect to any instruction shall not be
affected by your failure to receive such confirmation or by its contents.

<PAGE>   89

               Without limiting the foregoing, we hereby unconditionally
authorize any one of the above-designated persons to execute and submit requests
for advances of proceeds of the Loans (including the Initial Advance) and
notices of Elections, Conversions and Continuations to you under the Loan
Agreement with the identical force and effect in all respects as if executed and
submitted by us.

               You and the Banks shall be fully protected in, and shall incur no
liability to us for, acting upon any instructions which you in good faith
believe to have been given by any person designated above, and in no event shall
you or any Bank be liable for special, consequential or punitive damages. In
addition, we agree to hold you, the Banks and your and the Banks' agents
harmless from any and all liability, loss and expense arising directly or
indirectly out of instructions that we provide to you in connection with the
Loan Agreement except for liability, loss or expense occasioned by the gross
negligence or willful misconduct of you or your agents.

               Upon notice to us, you may, at your option, refuse to execute any
instruction, or part thereof, without incurring any responsibility for any loss,
liability or expense arising out of such refusal if you in good faith believe
that the person delivering the instruction is not one of the persons designated
above or if the instruction is not accompanied by an authentication method that
we have agreed to in writing.

               We will promptly notify you in writing of any change in the
persons designated above and, until you have actually received such written
notice and have had a reasonable opportunity to act upon it, you are authorized
to act upon instructions, even though the person delivering them may no longer
be authorized.

                                         Very truly yours,

the unpaid principal balance hereof, for the period such balance is outstanding,
in like money, at said office for the account of said Applicable Lending Office,

               The date and amount of each advance of the Ratable Loan made by

and UBS AG, Stamford Branch, as administrative agent for the Banks referred to
below (in such capacity, together with its successors in such capacity, the
"Administrative Agent").

                              Preliminary Statement

               1. This Assignment and Assumption Agreement (this "Agreement")
relates to the Revolving Credit Agreement dated March ___, 2000 (as the same may
be amended from time to time, the "Loan Agreement") among Borrower, Vornado
Realty Trust, the banks party thereto (each a "Bank" and, collectively, the
"Banks") and the Administrative Agent. All capitalized terms not otherwise
defined herein shall have the respective meanings set forth in the Loan
Agreement.

               2. Subject to the terms and conditions set forth in the Loan
Agreement, Assignor has made a Loan Commitment to Borrower.

               3. Assignor desires to assign to Assignee all of the rights of
Assignor under the Loan Agreement in respect of a portion of its Ratable Loan
and Loan Commitment thereunder in an amount equal to __________ Dollars
($__________) (collectively, the "Assigned Loan and Commitment"); and Assignee
desires to accept assignment of such rights and assume the corresponding
obligations from Assignor on such terms. No portion of any outstanding Bid Rate
Loans is being assigned hereby.

               NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements contained herein, the parties hereto agree as follows:

               SECTION 1. Assignment. Assignor hereby assigns and sells to
Assignee all of the rights of Assignor under the Loan Agreement in and to the
Assigned Loan and Commitment, and Assignee hereby accepts such assignment from
Assignor and assumes all of the obligations of Assignor under the Loan Agreement
with respect to the Assigned Loan and Commitment. Upon the execution and
delivery hereof by Assignor, Assignee, Borrower and the Administrative Agent and
the payment of the amount specified in Section 2 hereof required to be paid on
the date hereof, (1) Assignee shall, as of the commencement of business on the
date hereof, succeed to the rights and obligations of a Bank under the Loan
Agreement with a Loan and a Loan Commitment in amounts equal to the Assigned
Loan and Commitment (and the definition of Loan Commitment in the Loan Agreement
is revised accordingly), and (2) the Loan and Loan Commitment of Assignor shall,
as of the commencement of business on the date hereof, be reduced
correspondingly and Assignor released from its obligations under the Loan
Agreement to the extent such obligations have been assumed by Assignee. Assignor
represents and warrants

                                      E-1
<PAGE>   98

to Assignee (1) that Assignor is the legal and beneficial owner of the Assigned
Loan and Commitment free and clear of all liens and other encumbrances and (2)
that Assignor is legally authorized to enter into this Agreement. Except as
provided in the immediately preceding sentence, the assignment provided for
herein shall be without representation or warranty by, or recourse to, Assignor.
Assignee represents and warrants to Assignor that Assignee is legally authorized
to enter into this Agreement.

               SECTION 2. Payments. As consideration for the assignment and sale
contemplated in Section 1 hereof, Assignee shall pay to Assignor on the date
hereof in immediately available funds an amount equal to __________ Dollars
($___________) [insert the amount of that portion of Assignor's Loan being
assigned]. It is understood that any fees paid to Assignor under the Loan
Agreement are for the account of Assignor. Each of Assignor and Assignee hereby
agrees that if it receives any amount under the Loan Agreement which is for the
account of the other party hereto, it shall receive the same for the account of
such other party to the extent of such other party's interest therein and shall
promptly pay the same to such other party.

               SECTION 3. [Consent of Borrower and UBS and Acknowledgment by the
Administrative Agent;] Execution and Delivery of Note. [This Agreement is
conditioned upon the consent of UBS and, provided there exists no Event of
Default, Borrower and upon the acknowledgment by the Administrative Agent
pursuant to Section 12.05 of the Loan Agreement. The execution of this Agreement
by Borrower and the Administrative Agent is evidence of this consent and
acknowledgment, respectively. ONLY NECESSARY IF ASSIGNEE IS NOT A MAJORITY OWNED
SUBSIDIARY OF A BANK OR OF THE PARENT OF A BANK] Pursuant to Section 12.05 of
the Loan Agreement, Borrower has agreed to execute and deliver Ratable Loan
Notes payable to the respective orders of Assignee and Assignor to evidence the
assignment and assumption provided for herein.

               SECTION 4. Non-Reliance on Assignor. Assignor makes no
representation or warranty in connection with, and shall have no responsibility
with respect to, the solvency, financial condition, or statements of Borrower or
any other party to any Loan Document, or the validity and enforceability of the
obligations of Borrower or any other party to a Loan Document in respect of the
Loan Agreement or any other Loan Document. Assignee acknowledges that it has,
independently and without reliance on Assignor, and based on such documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and will continue to be responsible for
making its own independent appraisal of the business, affairs and financial
condition of Borrower and the other parties to the Loan Documents.

               SECTION 5.    Governing Law.  This Agreement shall be governed by
and construed in accordance with the laws of the State of New York.

               SECTION 6. Counterparts. This Agreement may be signed in any
number of counterparts, each of which shall be an original, with the same effect
as if the signatures thereto and hereto were upon the same instrument.

the Loan Agreement or hereunder without the withholding of any tax and agrees to
furnish the evidence of such exemption as specified therein and otherwise to
comply with the provisions of said Section 10.13.

                              DESIGNATION AGREEMENT

               Reference is made to that certain Revolving Credit Agreement
dated as of March ___, 2000 (as amended, supplemented or otherwise modified from
time to time, the "Loan Agreement") among [BORROWER], Vornado Realty Trust, the
Banks party thereto, and UBS AG, Stamford Branch, as administrative agent for
said banks. Terms defined in the Loan Agreement and not otherwise defined herein
are used herein with the same meaning.

               [BANK] ("Designor") and ____________________, a ________________
("Designee") agree as follows:

               1. Designor hereby designates Designee, and Designee hereby
accepts such designation, to have a right to make Bid Rate Loans pursuant to
Section 2.02 of the Loan Agreement. Any assignment by Designor to Designee of
its rights to make a Bid Rate Loan pursuant to such Section shall be effective
at the time of the funding of such Bid Rate Loan and not before such time.

               2. Except as set forth in Section 6 below, Designor makes no
representation or warranty and assumes no responsibility pursuant to this
Designation Agreement with respect to (a) any statements, warranties or
representations made in or in connection with any Loan Document or any other
instrument or document furnished pursuant thereto or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of any Loan Document
or any other instrument and document furnished pursuant thereto or (b) the
financial condition of Borrower or General Partner or the performance or
observance by Borrower or General Partner of any of their obligations under any
Loan Document or any other instrument or document furnished pursuant thereto.

               3. Designee (a) confirms that it has received a copy of each Loan
Document, together with copies of such financial statements and other documents
and information as it has deemed appropriate to make its own credit analysis and
decision to enter into this Designation Agreement; (b) agrees that it will
independently and without reliance upon Administrative Agent, Designor or any
other Bank, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under any Loan Document; (c) represents that it is a
Designated Lender; (d) appoints and authorizes Administrative Agent to take such
action as agent on its behalf and to exercise such powers and discretion under
any Loan Document as are delegated to Administrative Agent by the terms thereof,
together with such powers and discretion as are reasonably incidental thereto;
and (e) agrees that it will perform in accordance with their terms all of the
obligations which by the terms of any Loan Document are required to be performed
by it as a Bank.

<PAGE>   108

               4. Designee hereby appoints Designor as Designee's agent and
attorney-in-fact, and grants to Designor an irrevocable power of attorney, to
receive payments made for the benefit of Designee under the Loan Agreement, to
deliver and receive all communications and notices under the Loan Agreement and
other Loan Documents and to exercise on Designee's behalf all rights to vote and
to grant and make approvals, waivers, consents or amendments to or under the
Loan Agreement or other Loan Documents. Any document executed by Designor on
Designee's behalf in connection with the Loan Agreement or other Loan Documents
shall be binding on Designee. Borrower, Administrative Agent and each of the
Banks may rely on and are beneficiaries of this Designation Agreement.

               5. Following the execution of this Designation Agreement by
Designor and Designee, it will be delivered to Administrative Agent for
acceptance by Administrative Agent. The effective date for this Designation
Agreement (the "Effective Date") shall be the date of acceptance hereof by
Administrative Agent.

               6. Designor unconditionally agrees to pay or reimburse Designee
and save Designee harmless against all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever which may be imposed or asserted by any of the
parties to the Loan Documents against Designee, in its capacity as such, in any
way relating to or arising out of this Agreement or any other Loan Documents or
any action taken or omitted by the Designee hereunder or thereunder, provided
that Designor shall not be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements if the same results from Designee's gross negligence
or willful misconduct.

               7. As of the Effective Date, Designee shall be a party to the
Loan Agreement with a right to make Bid Rate Loans as a Bank pursuant to Section
2.02 of the Loan Agreement and the rights and obligations of a Bank related
thereto; provided, however, that Designee shall not be required to make payments
with respect to such obligations except to the extent of excess cash flow of
Designee which is not otherwise required to repay obligations of Designee which
are then due and payable. Notwithstanding the foregoing, Designor, as
administrative agent for Designee, shall be and remain obligated to Borrower,
Administrative Agent and the Banks for each and every of the obligations of
Designee and Designor with respect to the Loan Agreement, including, without
limitation, any indemnification obligations under Section 10.05 of the Loan
Agreement.

               8. This Designation Agreement shall be governed by, and construed
in accordance with, the laws of the State of New York.

               9. This Designation Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.
