the maturing Revolving Advance, then the amount the Borrower is required to pay
on account of the maturing Revolving Advance will be reduced by, as the case
may, that amount of the Price of the new Revolving Advance allocable to the
principal of the maturing Revolving Advance being renewed, or that amount of the
net proceeds of the MBS related to the Base Facility Advance then converted from
the maturing Revolving Advance.

Advance is the first day of the month following the month in which the Revolving
Advance is made, the Borrower shall pay interest on the original stated
principal amount of the Revolving Advance for the partial month period
commencing on the Closing Date for the Revolving Advance and ending on the last
day of the calendar month in which the Closing Date occurs, at a rate per annum
equal to the greater of (i) the Coupon Rate for the Revolving Advance as
determined in accordance with Section 2.05(b) and (ii) a rate reasonably
determined by the Lender, based on the Lender's cost of funds and approved in
advance, in writing, by the Borrower, pursuant to the procedures mutually agreed
upon by the Borrower and the Lender.

installment shall be payable on or prior to the Closing Date for the Revolving
Advance and shall apply to the first full calendar month of the MBS backed by
the Revolving Advance. Subsequent installments shall be payable on the first day
of each calendar month, commencing on the first day of the second full calendar
month of such MBS, until the maturity of such MBS. Each installment of the
Revolving Facility Fee shall be in an amount equal to the product of multiplying
(i) the Revolving Facility Fee, by (ii) the amount of the Revolving Advance, by

Revolving Advance ("MBS Imputed Interest Rate") and (ii) the Revolving Facility
Fee.

          (b)  Notwithstanding anything to the contrary in this Section, if a
Revolving Advance is not made on the first day of a calendar month, and the MBS
Issue Date for the MBS backed by the Revolving Advance is the first day of the
month following the month in which the Revolving Advance is made, the Coupon
Rate for such Revolving Advance for such period shall be the greater of (i) the
rate for the Revolving Advance determined in accordance with subsection (a) of
this Section and (ii) a rate determined by the Lender, based on the Lender's
cost of funds, and approved in advance, in writing, by the Borrower, pursuant to
procedures mutually agreed upon by the Borrower and the Lender.

     documents and instruments evidencing a lien or security interest in

                                      -23-

<PAGE>

     Borrower's assets [except the Substitute Collateral] shall be released)
     upon the satisfaction of all of the following conditions:

               (1)  Defeasance Notice. Borrower shall give Lender a notice (the
                    -----------------
          "Defeasance Notice", in the manner specified in Section 3.10(g)(4), on
           -----------------
          a form provided by Lender, specifying a Business Day (the "Defeasance
                                                                     ----------
          Closing Date") which Borrower desires to consummate the Defeasance.
          ------------
          The Defeasance Closing Date specified by Borrower may not be more than
          45 calendar days, nor less than 30 calendar days, after the date on
          which the Defeasance Notice is received by Lender. Borrower shall also
          specify in the Defeasance Notice the name, address and telephone
          number of Borrower for notices pursuant to Section 3.10(g)(4). The
          form Defeasance Notice provided by Lender specifies: (i) which
          Mortgaged Properties Borrower proposes to be released; (ii) the name,
          address and telephone number of Lender for notices pursuant to Section
          3.10(g)(4); (iii) the account(s) to which payments to Lender are to be
          made; (iv) whether a Fannie Mae Investment Security will be offered
          for use as the Substitute Collateral and, if not, that U.S. Treasury
          Securities will be the Substitute Collateral; (v) whether the
          Successor Borrower will be designated by Lender or Borrower; and (vi)
          if a Fannie Mae Investment Security is offered for use as the
          Substitute Collateral, the Defeasance Notice shall also include the
          amount of the Defeasance Commitment Fee.

          Any applicable Defeasance Commitment fee must be paid by Borrower and
          received by Lender no later than the date and time when Lender
          receives the Defeasance Notice from Borrower.

               (2)  Confirmation. After Lender has confirmed that the Defeasance
                    ------------
          is then permitted as provided in Section 3.10(d), and has confirmed
          that the terms of the Defeasance Notice are acceptable to Lender,
          Lender shall, with reasonable promptness, notify Borrower of such
          confirmation by signing the Defeasance Notice, attaching the Annual
          Yields for the Mortgage Payments beginning on the first day of the
          second calendar month after the Defeasance Closing Date and ending on
          the Stated Maturity Date (if a Fannie Mae Investment Security is
          offered as Substitute Collateral) and transmitting the signed
          Defeasance Notice to Borrower pursuant to Section 3.10(g)(4). If,

          with the foregoing, Lender does not receive the Defeasance Commitment
          Fee within five (5) Business Days after the Defeasance Notice
          Effective Date, then Borrower's right to obtain Defeasance pursuant to
          that Defeasance Notice shall terminate.

               (3)  Substitute Collateral. On or before the Defeasance Closing
                    ---------------------
          Date, Borrower shall deliver to Lender a pledge and security
          agreement, in form and substance satisfactory to Lender in its sole
          discretion (the "Pledge Agreement"), creating a first priority
                           ----------------
          perfected security interest in favor of Lender in substitute
          collateral constituting an Investment Security (the "Substitute
                                                               ----------
          Collateral"). The Pledge Agreement shall provide Borrower's
          ----------
          authorization and direction that all interest on, principal of and
          other amounts payable with respect to the Substitute Collateral shall
          be paid directly to Lender to be applied to Mortgage Payments due

                                      -24-

<PAGE>

          under the Base Facility Note subject to Defeasance. If the Substitute
          Collateral is issued in a certificated form and Borrower has
          possession of the certificate, the certificate shall be endorsed
          (either on the certificate or on a separate writing attached thereto)
          by Borrower as directed by Lender and delivered to Lender. If the
          Substitute Collateral is issued in an uncertificated form, or in a
          certificated form but Borrower does not have possession of the
          certificate, Borrower shall execute and deliver to Lender all
          documents and instruments required by Lender to create in Lender's
          favor a first priority perfected security interest in such Substitute
          Collateral, including a securities account control agreement or any
          other instrument or document required to perfect a security interest
          in each Substitute Collateral.

               (4)  Closing Documents. Borrower shall deliver to Lender on or
                    -----------------
          before the Defeasance Closing Date the documents described in Section
          3.10(b).

               (5)  Amounts Payable by Borrower. On or before the Defeasance
                    ---------------------------
          Closing Date, Borrower shall pay to Lender an amount equal to the sum
          of:

                    (A)  the Next Scheduled P&I Payment;

                    (B)  all other sums then due and payable under the Base
                         Facility Note subject to Defeasance, the Security
                         Instruments related to the Mortgaged Properties to be
                         released; and

                    (C)  all costs and expenses incurred by Lender or Servicer
                         in connection with the Defeasance, including the
                         reasonable fees and disbursements of Lender's or
                         Servicer's legal counsel.

               (6)  Defeasance Deposit. If a Fannie Mae Investment Security will
                    ------------------
          be the Substitute Collateral, then, on or before 3:00 p.m.,
          Washington, D.C. time, on the Defeasance Closing Date, Borrower shall
          pay the Defeasance Deposit (reduced by the Defeasance Commitment Fee)
          to Lender to be used by Lender to purchase the Fannie Mae Investment
          Security as Borrower's agent.

               (7)  Covenants, Representations and Warranties. On the Defeasance
                    -----------------------------------------
          Closing Date, all of the covenants of the relevant Borrower set forth
          in Articles XIII, XIV and XV of this Agreement and all of the
          representations and warranties of the Borrower set forth in Article
          XII of this Agreement are true and correct in all material respects.

               (8)  Geographical Diversification. If, as a result of the
                    ----------------------------
          Defeasance, Lender determines that the geographical diversification of
          the Collateral Pool is compromised (whether or not the Geographical
          Diversification Requirement is met), Lender may require that Borrower
          add or substitute Multifamily Residential Properties to the Collateral
          Pool in a number and having a valuation required to restore the
          geographical diversification of the Collateral Pool to a level at
          least as diverse as before the Defeasance.

               -----------------
     Lender on or before the Defeasance Closing Date pursuant to Section
     3.10(a)(4) are:

               (1) an opinion of counsel for Borrower, in form and substance
          satisfactory to Lender, to the effect that Lender has a valid and
          perfected lien and security interest of first priority in the
          Substitute Collateral and the principal and interest payable
          thereunder;

               (2) an opinion of counsel for Borrower, in form and substance
          satisfactory to Lender, that the Defeasance, including both Borrower's
          granting to Lender of a lien and security interest in the Substitute
          Collateral and the assignment and assumption by Successor Borrower,
          and each of them, when considered in combination and separately, are
          not subject to avoidance under any applicable federal or state laws,
          including Sections 547 and 548 of the U.S. Bankruptcy Code;

               (3) if a Fannie Mae Investment Security is not used as Substitute
          Collateral, and unless waived by Lender, a certificate in form and
          substance satisfactory to Lender, issued by an independent certified
          public accountant, or financial institution, approved by Lender, to
          the effect that the Substitute Collateral will generate the Scheduled
          Defeasance Payments;

               (4) unless waived by Lender, an opinion of counsel for Borrower
          in form and substance satisfactory to Lender, that the Defeasance will

          the meaning of Section 1001(c) of the Internal Revenue Code and the
          temporary and final regulations promulgated thereunder;

               (5) such other opinions, certificates, documents or instruments
          as Lender may reasonably request; and

               (6) three counterparts of the executed Assignment and Assumption
          Agreement described in Section 3.10(e).

          (c)  Release. Upon Borrower's compliance with the requirements of
               -------

     such Mortgaged Properties, including assignments of leases, fixture filings
     and other documents and instruments evidencing a lien or security interest
     in Borrower's assets [except the Substitute Collateral] shall be released).
     Lender shall, with reasonable promptness, execute and deliver to Borrower,

     requested by Borrower in order to evidence or confirm the release of
     Lender's liens and security interests described in the immediately

              (3) after Lender has accelerated the maturity of the unpaid
          principal balance of, accrued interest on, and other amounts payable

          (e) Assignment and Assumption. Upon Borrower's compliance with the
              -------------------------
     requirements of Section 3.10(a), Borrower shall assign all its obligations
     and rights under the relevant Base Facility Note, together with the

                                                        ------------------
     designated by Lender or, if not so designated by Lender, designated by
     Borrower and acceptable to Lender in its sole discretion. Borrower and
     Successor Borrower shall execute and deliver to Lender an assignment and
     assumption agreement on a form provided by Lender (the "Assignment and
                                                             --------------

     Borrower of the Substitute Collateral, subject to the lien and security
     interest in favor of Lender, (ii) the assumption by Successor Borrower of
     all liabilities and obligations of Borrower under the relevant Base
     Facility Note, and (iii) the release by Lender of Borrower from all
     liabilities and obligations under the relevant Base Facility Note. Lender
     shall, at Borrower's request and expense, execute and deliver releases,
     reconveyances and security interest terminations with respect to the
     released Mortgage Properties and all other collateral held by Lender
     (except the Defeasance Deposit). The Assignment and Assumption Agreement
     shall be executed by Lender with a counterpart to be returned by Lender to
     Borrower and Successor Borrower thereafter; provided, however, in all
     events that it shall not be a condition of Defeasance that the Assignment
     and Assumption Agreement be executed by Lender, or any Successor Borrower
     that is designated by Lender.

          (f) Agent. If the Defeasance Notice provides that Lender will make
              -----
     available a Fannie Mae Investment Security for purchase by Borrower for use
     as the Substitute Collateral, Borrower hereby authorizes Lender to use, and
     appoints Lender as its agent and attorney-in-fact for the purpose of using,
     the Defeasance Deposit (including any portion thereof that constitutes the
     Defeasance Commitment Fee) to purchase a Fannie Mae Investment Security.

          (g) Administrative Provisions.
              -------------------------

              (1) Fannie Mae Security Liquidated Damages. If Borrower timely
                  --------------------------------------
          pays the Defeasance Commitment Fee, and Lender and Borrower timely
          transmit a signed facsimile copy of the Defeasance Notice pursuant to
          Section 3.10(a)(2), but Borrower fails to perform its other
          obligations under Sections 3.10(a) and Section 3.10(e), Lender shall
          have the right to retain the Defeasance Commitment Fee as liquidated
          damages for Borrower's default, as Lender's sole and exclusive remedy,
          and, except as provided in Section 3.10(g)(2), Borrower shall be
          released from all further obligations under this Section 3.10.
          Borrower acknowledges that, from and after the date on which Lender
          has executed the Defeasance Notice under Section 3.10(a)(2) and
          Borrower has delivered the Defeasance Commitment Fee, Lender will
          incur financing costs in arranging and preparing for the purchase of
          the Substitute

                                      -27-

<PAGE>

     Collateral and in arranging and preparing for the release of the Mortgaged
     Properties from the lien of the Security Instruments in reliance on the
     executed Defeasance Notice. Borrower agrees that the Defeasance Commitment
     Fee represents a fair and reasonable estimate, taking into account all
     circumstances existing on the date of this Agreement, of the damages Lender
     will incur by reason of Borrower's default.

          (2) Third Party Costs. In the event that the Defeasance is not

     to reimburse Lender and Servicer for all third party costs and expenses

     executed Defeasance Notice, within 10 Business Days after Borrower receives
     a written demand for payment, accompanied by a statement, in reasonable
     detail, of Lender's and Servicer's third party costs and expenses.

          (3) Payments. All payments required to be made by Borrower to Lender
              --------
     or Servicer pursuant to this Section 3.10 shall be made by wire transfer of

     Servicer, as the case may be, in the Defeasance Notice.

          (4) Notice. The Defeasance Notice delivered pursuant to this Section
              ------
     3.10(g)(4) shall be in writing and shall be sent by telecopier or facsimile
     machine which automatically generates a transmission report that states the
     date and time of the transmission, the length of the document transmitted
     and the telephone number of the recipient's telecopier or facsimile machine
     (or shall be sent by any distribution media, whether currently existing or
     hereafter developed, including electronic mail and internet distribution,
     as approved by Lender). Any notice so sent addressed to the parties at
     their respective addresses designated in the Defeasance Notice pursuant to
     Section 3.10(a), shall be deemed to have been received on the date and time
     indicated on the transmission report of recipient. To be effective,
     Borrower must send the Defeasance Notice (as described above) so that
     Lender receives the Defeasance Notice no earlier than 11:00 a.m. and no
     later than 3:00 p.m. Washington, D.C. time on a Business Day.

invalidate the Advance Confirmation Instrument or otherwise affect in any way

the Advance Confirmation Instrument, the Revolving Facility Note or the other
Loan Documents, but is merely meant to facilitate evidencing the date of funding
and to confirm that the Advance Confirmation Instrument is not effective until

the Advance or the failure of the purchaser of the MBS to purchase such MBS),
the Borrower shall pay all breakage and other costs, fees and damages incurred
by the Lender in connection with its failure to fulfill the MBS Commitment. The
Lender reserves the right to require that the Borrower post a deposit at the

SECTION 7.01 Right to Obtain Releases of Collateral. Subject to the terms and
             --------------------------------------
conditions of this Article, the Borrower shall have the right to obtain a

Lender, in the form attached as Exhibit T to this Agreement. The Collateral
                                ---------
Release Request shall not result in a termination of all or any part of the

released from the Collateral Pool ("Collateral Release Property").
                                    ---------------------------

          (b)  Closing. If all conditions contained in Section 7.03 are
               -------
satisfied, the Lender shall cause the Collateral Release Property to be released
from the Collateral Pool, at a closing to be held at offices designated by the
Lender on a Closing Date selected by the Lender, and occurring within 30 days
after the Lender's receipt of the Collateral Release Request (or on such other
date to which the Borrower and the Lender may agree, provided that in any
Calendar Quarter, the Closing Date for any release shall be on the same day as
the Closing Date of any addition of an Additional Mortgaged Property to the
Collateral Pool pursuant to Article VI of this Agreement or any increase in the
Credit Facility pursuant to Article VIII of this Agreement), by executing and
delivering, and causing all applicable parties to execute and deliver, all at
the sole cost and expense of the Borrower, instruments, in the form customarily
used by the Lender and reasonably satisfactory to the Title Company for releases
in the jurisdiction governing the perfection of the security interest being
released, releasing the applicable Security Instrument as a Lien on the
Collateral Release Property, and UCC-3 Termination Statements terminating the
UCC-1 Financing Statements perfecting a Lien on the portion of the Collateral
Release Property comprised of personal property and such other documents and
instruments as the Borrower may reasonably request evidencing the release of the
applicable Collateral from any lien securing the Obligations (including a
termination of any restriction on the use of any accounts relating to the
Collateral Release Property) and the release and return to the Borrower of any
and all escrowed amounts relating thereto. The instruments referred to in the
preceding sentence are referred to in this Article as the "Collateral Release

Agreement means the greater of (i) the Allocable Facility Amount for the
Mortgaged Property to be released and (ii) the amount, if any, of Advances
Outstanding which are required to be repaid by the Borrower to the Lender in
connection with the proposed release of the Mortgaged Property from the
Collateral Pool, so that, immediately after the release, the Coverage and LTV
Tests will be satisfied and neither the Aggregate Debt Service Coverage Ratios
for the Trailing 12 Month Period will be reduced nor the Aggregate Loan to Value
Ratio for the Trailing 12 Month Period will be increased as a result of such
release. In addition to the Release Price, the Borrower shall pay to the Lender
all associated prepayment premiums and other amounts due under the Notes and any
Advance Confirmation Instruments evidencing the Advances being repaid.

        (d)  Application of Release Price. The Release Price shall be applied
             ----------------------------
against the Revolving Advances Outstanding until there are no further Revolving
Advances Outstanding, and thereafter shall be held by the Lender (or its
appointed collateral agent) as substituted Collateral ("Substituted Cash

----------
form and substance acceptable to the Lender (or, at the Borrower's option, may
be applied against the prepayment of Base Facility Advances, so long as the
prepayment is permitted under the Base Facility Note for the Base Facility
Advance). Any portion of the Release Price held as Substituted Cash Collateral
may be released if, immediately after giving effect to the release, each of the
conditions set forth in Section 7.03(a) below shall have been satisfied. If, on
the date on which the Borrower pays the Release Price, Revolving Advances are
Outstanding but are not then due and payable, the Lender shall hold the payments
as additional Collateral for the Credit Facility, until the next date on which
Revolving Advances are due and payable, at which time the Lender shall apply the

roadways, either by location of the phase on a dedicated, all-weather road or by
access to such a road by means of a satisfactory easement, (ii) have access
which is sufficiently attractive and direct from major thoroughfares to be
conducive to continued good marketing, (iii) have a location which is not (A)
inferior to other phases, (B) such that inadequate maintenance of other phases
would have a significant negative impact on the phase, and (C) such that the
phase is visible only after passing through the other phases of the project and

     other jurisdiction in which such qualification and/or standing is necessary

     ability of the Borrower to perform the Obligations under this Agreement and
     the other Loan Documents. The Borrower is qualified to transact business
     and is in good standing in each State in which it owns a Mortgaged
     Property.

     its corporate existence.

                                       -46-

<PAGE>

          (b)  Power and Authority. The Borrower has the requisite power and
               -------------------
authority (i) to own its properties and to carry on its business as now
conducted and as contemplated to be conducted in connection with the performance
of the Obligations hereunder and under the other Loan Documents and (ii) to
execute and deliver this Agreement and the other Loan Documents and to carry out
the transactions contemplated by this Agreement and the other Loan Documents.

          (c)  Due Authorization. The execution, delivery and performance of
               -----------------
this Agreement and the other Loan Documents have been duly authorized by all
necessary action and proceedings by or on behalf of the Borrower, and no further
approvals or filings of any kind, including any approval of or filing with any

condition to the valid execution, delivery and performance by the Borrower of
this Agreement or any of the other Loan Documents.

          (d)  Valid and Binding Obligations. This Agreement and the other Loan
               -----------------------------
Documents have been duly authorized, executed and delivered by the Borrower and
constitute the legal, valid and binding obligations of the Borrower, enforceable
against the Borrower in accordance with their respective terms, except as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws or equitable principles affecting the
enforcement of creditors' rights generally or by equitable principles or by the
exercise of discretion by any court.

          (e)  Non-contravention; No Liens. Neither the execution and delivery
               ---------------------------
of this Agreement and the other Loan Documents, nor the fulfillment of or
compliance with the terms and conditions of this Agreement and the other Loan
Documents nor the performance of the Obligations:

               (1) does or will conflict with or result in any breach or
     violation of any Applicable Law enacted or issued by any Governmental
     Authority or other agency having jurisdiction over the Borrower, any of the
     Mortgaged Properties or any other portion of the Collateral or other assets
     of the Borrower, or any judgment or order applicable to the Borrower or to
     which the Borrower, any of the Mortgaged Properties or other assets of the
     Borrower are subject;

               (2) does or will conflict with or result in any material breach
     or violation of, or constitute a default under, any of the terms,
     conditions or provisions of the Borrower's Organizational Documents, any
     indenture, existing agreement or other instrument to which the Borrower is
     a party or to which the Borrower, any of the Mortgaged Properties or any

     of the Borrower, any Governmental Authority or any other Person except such

                                      -47-

<PAGE>

          (f)  Pending Litigation or other Proceedings. There is no pending or,
               ---------------------------------------
to the best knowledge of the Borrower, threatened action, suit, proceeding or
investigation, at law or in equity, before any court, board, body or official of
any Governmental Authority or arbitrator against or affecting any Mortgaged
Property or any other portion of the Collateral or other assets of the Borrower,
which, if decided adversely to the Borrower, would have, or may reasonably be
expected to have, a Material Adverse Effect. The Borrower is not in default with
respect to any order of any Governmental Authority.

          (g)  Solvency. The Borrower is not insolvent and will not be rendered
               --------
insolvent by the transactions contemplated by this Agreement or the other Loan
Documents and after giving effect to such transactions, the Borrower will not be
left with an unreasonably small amount of capital with which to engage in its
business or undertakings, nor will the Borrower have incurred, have intended to
incur, or believe that it has incurred, debts beyond its ability to pay such
debts as they mature. The Borrower did not receive less than a reasonably
equivalent value in exchange for incurrence of the Obligations. There (i) is no
contemplated, pending or, to the best of the Borrower's knowledge, threatened
bankruptcy, reorganization, receivership, insolvency or like proceeding, whether
voluntary or involuntary, affecting the Borrower or any of the Mortgaged
Properties and (ii) has been no assertion or exercise of jurisdiction over the
Borrower or any of the Mortgaged Properties by any court empowered to exercise

or, to the knowledge of the Borrower, by any other Person under any contract to
which the Borrower is a party relating to any Mortgaged Property, including any
management, rental, service, supply, security, maintenance or similar contract,
other than defaults which do not permit the non-defaulting party to terminate
the contract and which do not have, and are not reasonably expected to have, a
Material Adverse Effect. Neither the Borrower nor, to the knowledge of the
Borrower, any other Person, has received notice or has any knowledge of any
existing circumstances in respect of which it could receive any notice of
default or breach in respect of any contracts affecting or concerning any
Mortgaged Property, which would have a Material Adverse Effect.

          (i)  Compliance with the Loan Documents. The Borrower is in compliance
               ----------------------------------
with all provisions of the Loan Documents to which it is a party or by which it
is bound. The representations and warranties made by the Borrower in the Loan
Documents are true, complete and correct as of the Closing Date and do not
contain any untrue statement of material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements made
therein, in light of the circumstances under which they were made, not
misleading.

          (j)  ERISA. The Borrower is in compliance in all material respects
               -----
with all applicable provisions of ERISA and has not incurred any liability to
the PBGC on a Plan under Title IV of ERISA. None of the assets of the Borrower
constitute plan assets (within the meaning of Department of Labor Regulation (S)
2510.3-101) of any employee benefit plan subject to Title I of ERISA.

          (k)  Financial Information. The financial projections relating to the
               ---------------------
Borrower and delivered to the Lender on or prior to the date hereof, if any,
were prepared on the basis of assumptions believed by the Borrower, in good
faith at the time of preparation, to be reasonable and the Borrower is not aware
of any fact or information that would lead it to believe that such

                                      -48-

<PAGE>

assumptions are incorrect or misleading in any material respect; provided,
however, that no representation or warranty is made that any result set forth in
such financial projections shall be achieved. The financial statements of the
Borrower which have been furnished to the Lender are complete and accurate in
all material respects and present fairly the financial condition of the
Borrower, as of its date in accordance with GAAP, applied on a consistent basis,
and since the date of the most recent of such financial statements no event has
occurred which would have, or may reasonably be expected to have a Material
Adverse Effect, and there has not been any material transaction entered into by
the Borrower other than transactions in the ordinary course of business. The
Borrower has no material contingent obligations which are not otherwise
disclosed in its most recent financial statements.

          (l)  Accuracy of Information. No information, statement or report
               -----------------------
furnished in writing to the Lender by the Borrower in connection with this
Agreement or any other Loan Document or in connection with the consummation of
the transactions contemplated hereby and thereby contains any material
misstatement of fact or omits to state a material fact necessary to make the
statements contained therein, in light of the circumstances under which they
were made, not misleading; and the representations and warranties of the
Borrower and the statements, information and descriptions contained in the
Borrower's closing certificates, as of the Closing Date, are true, correct and
complete in all material respects, do not contain any untrue statement or
misleading statement of a material fact, and do not omit to state a material
fact required to be stated therein or necessary to make the certifications,
representations, warranties, statements, information and descriptions contained
therein, in light of the circumstances under which they were made, not
misleading; and the estimates and the assumptions contained herein and in any
certificate of the Borrower delivered as of the Closing Date are reasonable and
based on the best information available to the Borrower.

          (m)  Intentionally Omitted.
               ---------------------

          (n)  Governmental Approvals. No Governmental Approval not already
               ----------------------
obtained or made is required for the execution and delivery of this Agreement or
any other Loan Document or the performance of the terms and provisions hereof or
thereof by the Borrower.

          (o)  Governmental Orders. The Borrower is not presently under any
               -------------------
cease or desist order or other orders of a similar nature, temporary or
permanent, of any Governmental Authority which would have the effect of
preventing or hindering performance of its duties hereunder, nor are there any
proceedings presently in progress or to its knowledge contemplated which would,
if successful, lead to the issuance of any such order.

          (p)  No Reliance. The Borrower acknowledges, represents and warrants
               -----------
that it understands the nature and structure of the transactions contemplated by
this Agreement and the other Loan Documents, that it is familiar with the
provisions of all of the documents and instruments relating to such
transactions; that it understands the risks inherent in such transactions,
including the risk of loss of all or any of the Mortgaged Properties; and that
it has not relied on the Lender or Fannie Mae for any guidance or expertise in
analyzing the financial or other consequences of the transactions contemplated
by this Agreement or any other Loan Document or otherwise relied on the Lender
or Fannie Mae in any manner in connection with interpreting,

                                      -49-

<PAGE>

entering into or otherwise in connection with this Agreement, any other Loan
Document or any of the matters contemplated hereby or thereby.

               (q) Compliance with Applicable Law. The Borrower is in compliance
                   ------------------------------
with Applicable Law, including all Governmental Approvals, if any, except for
such items of noncompliance that, singly or in the aggregate, have not had and
are not reasonably expected to cause, a Material Adverse Effect.

               (r) Contracts with Affiliates. Except as otherwise approved in
                   -------------------------
writing by the Lender, the Borrower has not entered into and is not a party to
any contract, lease or other agreement with any Affiliate of the Borrower for
the provision of any service, materials or supplies to any Mortgaged Property
(including any contract, lease or agreement for the provision of property
management services, cable television services or equipment, gas, electric or
other utilities, security services or equipment, laundry services or equipment
or telephone services or equipment).

               (s) Lines of Business. Not less than sixty percent (60%) of the
                   -----------------
Consolidated Total Assets of each Borrower consist of Multifamily Residential
Properties.

               (t) Status as a Real Estate Investment Trust. UDRT is qualified,
                   ----------------------------------------
and is taxed as, a real estate investment trust under Subchapter M of the
Internal Revenue Code, and is not engaged in any activities which would
jeopardize such qualification and tax treatment.

SECTION 12.02  Representations and Warranties of the Borrower. The Borrower
               ----------------------------------------------
owning a Mortgaged Property hereby represents and warrants to the Lender as
follows with respect to each of the Mortgaged Properties owned by it:

               (a) Title. The relevant Borrower has good, valid, marketable and
                   -----
indefeasible title to each Mortgaged Property (either in fee simple or as tenant
under a ground lease meeting all of the requirements of the DUS Guide), free and
clear of all Liens whatsoever except the Permitted Liens. Each Security
Instrument, if and when properly recorded in the appropriate records, together
with any Uniform Commercial Code financing statements required to be filed in
connection therewith, will create a valid, perfected first lien on the Mortgaged
Property intended to be encumbered thereby (including the Leases related to such
Mortgaged Property and the rents and all rights to collect rents under such
Leases), subject only to Permitted Liens. Except for any Permitted Liens, there
are no Liens or claims for work, labor or materials affecting any Mortgaged
Property which are or may be prior to, subordinate to, or of equal priority
with, the Liens created by the Loan Documents. The Permitted Liens do not have,
and may not reasonably be expected to have, a Material Adverse Effect.

               (b) Impositions. The Borrower has filed all property and similar
                   -----------
tax returns required to have been filed by it with respect to each Mortgaged
Property and has paid and discharged, or caused to be paid and discharged, all
installments for the payment of all Taxes due to date, and all other material
Impositions imposed against, affecting or relating to each Mortgaged Property
other than those which have not become due, together with any fine, penalty,
interest or cost for nonpayment pursuant to such returns or pursuant to any
assessment received by it. Except for any Tax, levy or other assessment or
charge resulting from a reassessment of the value of a Mortgaged Property in the
ordinary course of business, the Borrower has no knowledge of any new

                                      -50-

<PAGE>

proposed Tax, levy or other governmental or private assessment or charge in
respect of any Mortgaged Property which has not been disclosed in writing to the
Lender.

               (c) Zoning. Each Mortgaged Property complies in all material
                   ------
respects with all Applicable Laws affecting such Mortgaged Property. Without
limiting the foregoing, all material Permits, including certificates of
occupancy, have been issued and are in full force and effect. Neither the
Borrower nor, to the knowledge of the Borrower, any former owner of any
Mortgaged Property, has received any written notification or threat of any
actions or proceedings regarding the noncompliance or nonconformity of any
Mortgaged Property with any Applicable Laws or Permits, nor is the Borrower
otherwise aware of any such pending actions or proceedings.

               (d) Leases. The Borrower has delivered to the Lender a true and
                   ------
correct copy of its form apartment lease for each Mortgaged Property (and, with
respect to leases executed prior to the date on which the Borrower first owned
the Mortgaged Property, the form apartment lease used for such leases), and each
Lease with respect to such Mortgaged Property is in the form thereof, with no
material modifications thereto, except as previously disclosed in writing to the
Lender. Except as set forth in a Rent Roll, no Lease for any unit in any
Mortgaged Property (i) is for a term in excess of one year, including any
renewal or extension period unless such renewal or extension period is subject
to termination by the Borrower upon not more than 30 days' written notice, (ii)
provides for prepayment of more than one month's rent, or (iii) was entered into
in other than the ordinary course of business.

               (e) Rent Roll. The Borrower has executed and delivered to the
                   ---------
Lender a Rent Roll for each Mortgaged Property, each dated as of and delivered
within 30 days prior to the Closing Date. Each Rent Roll sets forth each and
every unit subject to a Lease which is in full force and effect as of the date
of such Rent Roll. The information set forth on each Rent Roll is true, correct
and complete in all material respects as of its date and there has occurred no
material adverse change in the information shown on any Rent Roll from the date
of each such Rent Roll to the Closing Date. Except as disclosed in the Rent Roll

insurance or bond. No claims have been made against any contractor, architect or
other party with respect to the condition of any Mortgaged Property or the

 -----------
of the Lender; provided, however, that in any case, no such Alteration shall be
               --------  -------
made to any Mortgaged Property without the prior written consent of the Lender

value of such Mortgaged Property or its operation as a multifamily housing
facility in substantially the same manner in which it is being operated on the

regulation permitting, authorizing or requiring such Loan Document Taxes to be
levied, assessed or charged, which law or regulation in the opinion of counsel

                  (a)  Prohibition on Transfers and Changes of Control. The

         Property or Lender's interest in the Mortgaged Property and Borrower
         pays to Lender, on demand, all costs and expenses incurred by Lender in

         utility easement serving a Mortgaged Property to a publicly operated
         utility, or (B) the grant of an easement related to expansion or
         widening of roadways, provided that any such easement is in form and
         substance reasonably acceptable to Lender and does not materially and
         adversely affect the access, use or marketability of a Mortgaged
         Property.

                        (v)   The transfer of shares of common stock,

         either upon such transfer or upon the subsequent conversion to equity
         or such convertible debt or other securities.

                        (vi)  The issuance by Borrower of additional limited
         partnership units or convertible debt, equity, membership interests,
         and other similar securities, and the subsequent transfer of such units
         or other securities; provided, however, that no Change in Control

         by Borrower, provided that (A) Borrower is the surviving entity after
         such merger or acquisition, (B) no Change in Control occurs, and (C)
         such merger or acquisition does not result in an Event of Default, as
         such terms are defined in this Agreement.

otherwise violate this Section 13.21 if, prior to the Transfer or Change of
Control, Borrower has satisfied each of the following requirements:

         assumption agreement that is acceptable to Lender and that, among other

Borrower shall maintain Mortgaged Properties in the Collateral Pool so that the
Collateral Pool consists of at least nine (9) Mortgaged Properties located in at
least five (5) SMSA's, provided, however, that, upon the occurrence of any
increase in the Commitment pursuant to Article VIII, the Borrower shall at all
times thereafter cause the Collateral Pool to satisfy such other Geographical

prepayments made pursuant to the preceding sentence shall be applied first
against the Variable Advances Outstanding in the sequence specified by Borrower
until there are no further Variable Advances Outstanding then against the
prepayment of Fixed Advances Outstanding so long as the prepayment is permitted

accordance with a security agreement and other documents in form and substance
acceptable to Lender. Any Substitute Cash Collateral remaining will be returned

required by this Section, Variable Advances are Outstanding but are not then due
and payable, Lender shall hold such amounts (which amounts shall bear interest
at a rate determined by Lender) as additional collateral until the next date on
the Variable Advances are due and payable at which time Lender shall apply the

to it at law or in equity, including obtaining specific performance and
injunctive relief.

SECTION 18.02 Waivers; Rescission of Declaration. The Lender shall have the
              ----------------------------------
right, to be exercised in its complete discretion, to waive any breach hereunder
(including the occurrence of an Event of Default), by a writing setting forth
the terms, conditions, and extent of such waiver signed by the Lender and
delivered to the Borrower. Unless such writing expressly provides to the
contrary, any waiver so granted shall extend only to the specific event or
occurrence which gave rise to the waiver and not to any other similar event or
occurrence which occurs subsequent to the date of such waiver.

SECTION 18.03 The Lender's Right to Protect Collateral and Perform Covenants and
              ------------------------------------------------------------------
Other Obligations. If the Borrower fails to perform the covenants and agreements
-----------------
contained in this Agreement or any of the other Loan Documents, then the Lender
at the Lender's option may make such appearances, disburse such sums and take
such action as the Lender deems necessary, in its sole discretion, to protect
the Lender's interest, including (i) disbursement of attorneys' fees, (ii) entry
upon the Mortgaged Property to make repairs and Replacements, (iii) procurement
of satisfactory insurance as provided in paragraph 5 of the Security Instrument
encumbering the Mortgaged Property, and (iv) if the Security Instrument is on a
leasehold, exercise of any option to renew or extend the ground lease on behalf
of the Borrower and the curing of any default of the Borrower in the terms and
conditions of the ground lease. Any amounts disbursed by the Lender pursuant to
this Section, with interest thereon, shall become additional indebtedness of the
Borrower secured by the Loan Documents. Unless the Borrower and the Lender agree
to other terms of payment, such amounts shall be immediately due and payable and
shall bear interest from the date of disbursement at the weighted average, as
determined by Lender, of the interest rates in effect

                                      -75-

Borrower under applicable law. Nothing contained in this Section shall require
the Lender to incur any expense or take any action hereunder.

SECTION 18.04 No Remedy Exclusive. Unless otherwise expressly provided, no
              -------------------
remedy herein conferred upon or reserved is intended to be exclusive of any
other available remedy, but each remedy shall be cumulative and shall be in
addition to other remedies given under the Loan Documents or existing at law or
in equity.

SECTION 18.05 No Waiver. No delay or omission to exercise any right or power
              ---------
accruing under any Loan Document upon the happening of any Event of Default or
Potential Event of Default shall impair any such right or power or shall be
construed to be a waiver thereof, but any such right and power may be exercised
from time to time and as often as may be deemed expedient.

SECTION 18.06 No Notice. In order to entitle the Lender to exercise any remedy
              ---------
reserved to the Lender in this Article, it shall not be necessary to give any
notice, other than such notice as may be required under the applicable
provisions of this Agreement or any of the other Loan Documents.

SECTION 18.07 Application of Payments. Except as otherwise expressly provided in
              -----------------------
the Loan Documents, and unless applicable law provides otherwise, (i) all
payments received by the Lender from the Borrower under the Loan Documents shall
be applied by the Lender against any amounts then due and payable under the Loan
Documents by the Borrower, in any order of priority that the Lender may
determine and (ii) the Borrower shall have no right to determine the order of
priority or the allocation of any payment it makes to the Lender.

to Articles VII or X. The Borrower acknowledges that the Security Instruments
provide for the release of the Collateral under Articles VII and X. Accordingly,
the Borrower shall not look to the Lender for performance of any obligations set
forth in Articles VII and X, but shall look solely to the party secured by the
Collateral to be released for such performance. The Lender represents and
warrants to the Borrower that the party secured by the Collateral shall be
subject to the release and substitution provisions contained in Articles VII and
X by virtue of the release provisions in each Security Instrument.

other Loan Documents, and/or any related servicing obligations, and, at Fannie
Mae's option, the concurrent release of the Lender from its obligations under
this Agreement and the other Loan Documents, and/or any related servicing
obligations, and shall execute all releases, modifications and other documents
which Fannie Mae determines are necessary or desirable to effect such
assumption.

              ---------------------------------------
any provision providing for the payment of fees, costs or expenses incurred or
charged by the Lender pursuant to this Agreement shall be deemed to provide for
the Borrower's payment of all reasonable fees, costs and expenses incurred or
charged by the Lender or Fannie Mae in connection with the matter for which
fees, costs or expenses are payable.

SECTION 19.06 Third-Party Beneficiary. The Borrower hereby acknowledges and
              -----------------------
agrees that Fannie Mae is a third party beneficiary of all of the
representations, warranties and covenants made by the Borrower to, and all
rights under this Agreement conferred upon, the Lender, and, by virtue of its
status as third-party beneficiary and/or assignee of the Lender's rights under
this Agreement, Fannie Mae shall have the right to enforce all of the provisions
of this Agreement against the Borrower.

Borrower personally without regard to whether the Lender has exercised any
rights against the Mortgaged Property or any other security, or pursued any

Lender under the Loan Documents or applicable law. For purposes of this Article,
the term "Mortgaged Property" shall not include any funds that (1) have been
applied by the Borrower as required or permitted by the Loan Documents prior to
the occurrence of an Event of Default, or (2) are owned by the Borrower and
which the Borrower was unable to apply as required or permitted by the Loan
Documents because of a bankruptcy, receivership, or similar judicial proceeding.

more counterparts. All counterparts shall collectively constitute a single
agreement. It shall not be necessary in making proof of this Agreement to
produce or account for more than the number of counterparts containing the
respective signatures of, or on behalf of, all of the parties hereto.

SECTION 23.02 Amendments, Changes and Modifications. This Agreement may be
              -------------------------------------
amended, changed, modified, altered or terminated only by written instrument or

connection with:

           (a) Any amendment, consent or waiver to this Agreement or any of the
Loan Documents (whether or not any such amendments, consents or waivers are
entered into).

           (b) Defending or participating in any litigation arising from actions
by third parties and brought against or involving the Lender with respect to (i)
any Mortgaged Property, (ii) any event, act, condition or circumstance in

assessments or charges made by any governmental authority by reason of the
execution, delivery, filing, recordation, performance or enforcement of any of
the Loan Documents or the Advances. However, the Borrower will not be obligated
to pay any franchise, estate, inheritance, income, excess profits or similar tax
on the Lender. Any attorneys' fees and expenses payable by the Borrower pursuant
to this Section shall be recoverable separately from and in addition to any
other amount included in such judgment, and such obligation is intended to be
severable from the other provisions of this Agreement and to survive and not be
merged into any such judgment. Any amounts payable by the Borrower pursuant to
this Section, with interest thereon if not paid when due, shall become
additional indebtedness of the Borrower secured by the Loan Documents. Such
amounts shall bear interest from the date such amounts are due until paid in
full at the weighted average, as determined by Lender, of the interest rates in
effect from time to time for each Advance unless collection from the Borrower of
interest at such rate would be contrary to applicable law, in which event such
amounts shall bear interest at the highest rate which may be collected from the
Borrower under applicable law. The provisions of this Section are cumulative
with, and do not exclude the application and benefit to the Lender of, any
provision of any other Loan Document relating to any of the matters covered by
this Section.

SECTION 23.04  Payment Procedure. All payments to be made to the Lender pursuant

transfer to an account designated by the Lender before 1:00 p.m. (Washington,

                                      -79-

<PAGE>

then such payment or expiration of such time period need not occur on such date
but may be made on the next succeeding Business Day with the same force and
effect as if made on the day of maturity or expiration of such period, except
that interest shall continue to accrue for the period after such date to the
next Business Day.

SECTION 23.06   Choice of Law; Consent to Jurisdiction; Waiver of Jury Trial.

LOAN DOCUMENTS, INCLUDING THOSE CONTROVERSIES RELATING TO THE EXECUTION,

WITH RESPECT TO ANY ISSUE ARISING UNDER ANY OF THE LOAN DOCUMENTS TRIABLE BY A
JURY AND (II) WAIVES ANY RIGHT TO TRIAL BY JURY TO THE EXTENT THAT ANY SUCH
RIGHT SHALL NOW OR HEREAFTER EXIST. THIS WAIVER IS INTENDED TO ENCOMPASS
INDIVIDUALLY EACH INSTANCE AND EACH ISSUE AS TO WHICH THE RIGHT TO A JURY TRIAL
WOULD OTHERWISE ACCRUE. FURTHER, THE BORROWER HEREBY CERTIFIES THAT NO
REPRESENTATIVE OR AGENT OF LENDER (INCLUDING, BUT NOT LIMITED TO, LENDER'S
COUNSEL) HAS REPRESENTED, EXPRESSLY OR OTHERWISE, TO THE BORROWER THAT LENDER
WILL NOT SEEK TO ENFORCE THE PROVISIONS OF THIS SECTION. THE FOREGOING
PROVISIONS WERE KNOWINGLY, WILLINGLY AND VOLUNTARILY AGREED TO BY THE BORROWER
UPON CONSULTATION WITH INDEPENDENT LEGAL COUNSEL SELECTED BY THE BORROWER'S FREE
WILL.

               ------------
any other Loan Document shall be held invalid, illegal or unenforceable in any

     multiple of $500,000 in excess thereof (or, in the case of a Borrowing of
     Revolving Loans, if less, in the amount of the aggregate Unutilized
     Revolving Credit Commitments), and the aggregate principal amount of each
     Borrowing comprised of LIBOR Loans shall not be less than $3,000,000 or, if
     greater, an integral multiple of $1,000,000 in excess thereof;

          (ii) if the Borrower shall have failed to designate the Type of Loans
     comprising a Borrowing, the Borrower shall be deemed to have requested a
     Borrowing comprised of Base Rate Loans; and

          (iii) if the Borrower shall have failed to select the duration of the
     Interest Period to be applicable to any Borrowing of LIBOR Loans, then the
     Borrower shall be deemed to have selected an Interest Period with a
     duration of one month.

     (c) Not later than 1:00 p.m. (Charlotte, North Carolina time) on the
requested Borrowing Date, each Lender will make available to the Agent at its
office referred to in Section 11.5 (or at such other location as the Agent may
designate) an amount, in Dollars and in immediately available funds, equal to
the amount of the Loan or Loans to be made by such Lender. To the extent the
Lenders have made such amounts available to the Agent as provided hereinabove,
the Agent will make the aggregate of such amounts available to the Borrower in
accordance with Section 2.3(a) and in like funds as received by the Agent.

     (d) In order to make a Borrowing of a Swingline Loan, the Borrower will
give the Agent (and the Swingline Lender, if the Swingline Lender is not also
the Agent) written notice not later than 12:00 p.m. noon (Charlotte, North
Carolina time) on the day of such Borrowing (which shall be a Business Day).
Each such notice (each, a "Notice of Swingline Borrowing") shall be irrevocable,
shall be given in the form of Exhibit B-2 and shall specify (i) the principal
amount of the Swingline Loan to be made pursuant to such Borrowing (which shall
not be less than $1,000,000 and, if greater, shall be in an integral multiple of
$500,000 in excess thereof (or, if less, in the amount of the Unutilized
Swingline Commitment)) and (ii) the requested Borrowing Date, which shall be a
Business Day. Not later than 1:00 p.m. (Charlotte, North Carolina time) on the
requested Borrowing Date, the Swingline Lender will make available to the Agent
at its office referred to in Section 11.5 (or at such other location as the
Agent may designate) an amount, in Dollars and in immediately available funds,
equal to the amount of the requested Swingline Loan. To the extent the Swingline
Lender has made such amount available to the Agent as provided hereinabove, the
Agent will make such amount available to the Borrower in accordance with Section
2.3(a) and in like funds as received by the Agent. Notwithstanding the foregoing
or anything else herein to the contrary, at any time that a "Sweep

                                       27
<PAGE>

Plus" or similar cash management program is in effect between the Borrower and
First Union, as the Swingline Lender, each Borrowing and each voluntary
repayment of the Swingline Loans by the Borrower shall be made exclusively in
accordance with the procedures of such cash management program.

     (e) With respect to any outstanding Swingline Loans, the Swingline Lender
may at any time (whether or not an Event of Default has occurred and is
continuing) in its sole and absolute discretion (and is hereby authorized and
empowered by the Borrower to), cause a Borrowing of Revolving Loans to be made
for the purpose of repaying such Swingline Loans by delivering to the Agent (if
the Agent is not also the Swingline Lender) and each other Revolving Credit
Lender (on behalf of, and with a copy to, the Borrower), not later than 11:00
a.m. (Charlotte, North Carolina time) one (1) Business Day prior to the proposed
Borrowing Date therefor, a notice (which shall be deemed to be a Notice of
Borrowing given by the Borrower) requesting the Revolving Credit Lenders to make
Revolving Loans (which shall be made initially as Base Rate Loans) on such
Borrowing Date in an aggregate amount equal to the amount of such Swingline
Loans (the "Refunded Swingline Loans") outstanding on the date such notice is
given that the Swingline Lender requests to be repaid. Not later than 1:00 p.m.
(Charlotte, North Carolina time) on the requested Borrowing Date, each Revolving
Credit Lender (other than the Swingline Lender) will make available to the Agent
at its office referred to in Section 11.5 (or at such other location as the
Agent may designate) an amount, in Dollars and in immediately available funds,
equal to the amount of the Revolving Loan to be made by such Lender. To the
extent the Revolving Credit Lenders have made such amounts available to the
Agent as provided hereinabove, the Agent will make the aggregate of such amounts
available to the Swingline Lender in like funds as received by the Agent, to be
applied in repayment of the Refunded Swingline Loans. Notwithstanding any
provision of this Agreement to the contrary, on the relevant Borrowing Date, the
Refunded Swingline Loans (including the Swingline Lender's ratable share
thereof, in its capacity as a Revolving Credit Lender) shall be deemed to be
repaid with the proceeds of the Revolving Loans made as provided above
(including a Revolving Loan deemed to have been made by the Swingline Lender),
and such Refunded Swingline Loans deemed so to be repaid shall no longer be
outstanding as Swingline Loans but shall be outstanding as Revolving Loans. If
any portion of any such amount repaid (or deemed to be repaid) to the Swingline
Lender shall be recovered by or on behalf of the Borrower from the Swingline
Lender in any bankruptcy, insolvency or similar proceeding or otherwise, the
loss of the amount so recovered shall be shared ratably among all the Revolving
Credit Lenders in the manner contemplated by Section 2.15.

     (f) If, as a result of any bankruptcy, insolvency or similar proceeding
with respect to the Borrower, Revolving Loans are not made pursuant to Section
2.2(e) in an amount sufficient to repay any amounts owed to the Swingline Lender
in respect of any outstanding Swingline Loans, or if the Swingline Lender is
otherwise precluded for any reason from giving a notice on behalf of the
Borrower as provided for hereinabove, the Swingline Lender shall be deemed to
have sold without recourse, representation or warranty, and each Revolving
Credit Lender shall be deemed to have purchased and hereby agrees to purchase, a
participation in such outstanding Swingline Loans in an amount equal to its
ratable share (based on the proportion that its Revolving Credit Commitment
bears to the aggregate Revolving Credit Commitments at such time) of the unpaid
amount thereof together with accrued interest thereon. Upon one (1) Business
Day's prior notice from the Swingline Lender, each Revolving Credit Lender
(other

                                       28
<PAGE>

than the Swingline Lender) will make available to the Agent at its office
referred to in Section 11.5 (or at such other location as the Agent may
designate) an amount, in Dollars and in immediately available funds, equal to
its respective participation. To the extent the Revolving Credit Lenders have
made such amounts available to the Agent as provided hereinabove, the Agent will
make the aggregate of such amounts available to the Swingline Lender in like
funds as received by the Agent. In the event any such Revolving Credit Lender
fails to make available to the Agent the amount of such Lender's participation
as provided in this Section 2.2(f), the Swingline Lender shall be entitled to
recover such amount on demand from such Lender, together with interest thereon
for each day from the date such amount is required to be made available for the
account of the Swingline Lender until the date such amount is made available to
the Swingline Lender at the Federal Funds Rate for the first three (3) Business
Days and thereafter at the Adjusted Base Rate applicable to Revolving Loans.
Promptly following its receipt of any payment by or on behalf of the Borrower in
respect of a Swingline Loan, the Swingline Lender will pay to each Revolving
Credit Lender that has acquired a participation therein such Lender's ratable
share of such payment.

     (g) Notwithstanding any provision of this Agreement to the contrary, the
obligation of each Revolving Credit Lender (other than the Swingline Lender) to
make Revolving Loans for the purpose of repaying any Refunded Swingline Loans
pursuant to Section 2.2(e) and each such Lender's obligation to purchase a
participation in any unpaid Swingline Loans pursuant to Section 2.2(f) shall be
absolute and unconditional and shall not be affected by any circumstance or
event whatsoever, including, without limitation, (i) any set-off, counterclaim,
recoupment, defense or other right that such Lender may have against the
Swingline Lender, the Agent, the Borrower or any other Person for any reason
whatsoever, (ii) the occurrence or continuance of any Default or Event of
Default, (iii) any adverse change in the business, operations, properties,
assets, condition (financial or otherwise) or prospects of the Borrower or any
of its Subsidiaries, or (iv) any breach of this Agreement by any party hereto.

     2.3  Disbursements; Funding Reliance; Domicile of Loans.
          --------------------------------------------------

     (a) The Borrower hereby authorizes the Agent to disburse the proceeds of
each Borrowing in accordance with the terms of any written instructions from any
of the Authorized Officers, provided that the Agent shall not be obligated under
                            --------
any circumstances to forward amounts to any account not listed in an Account
Designation Letter. The Borrower may at any time deliver to the Agent an Account
Designation Letter listing any additional accounts or deleting any accounts
listed in a previous Account Designation Letter.

     (b) Unless the Agent has received, prior to 1:00 p.m. (Charlotte, North
Carolina time) on the relevant Borrowing Date, written notice from a Lender that
such Lender will not make available to the Agent such Lender's ratable portion,
if any, of the relevant Borrowing, the Agent may assume that such Lender has
made such portion available to the Agent in immediately available funds on such
Borrowing Date in accordance with the applicable provisions of Section 2.2, and
the Agent may, in reliance upon such assumption, but shall not be obligated to,
make a corresponding amount available to the Borrower on such Borrowing Date. If
and to the extent that such Lender shall not have made such portion available to
the Agent, and the Agent shall have made such corresponding amount available to
the Borrower, such Lender, on the one hand, and the Borrower, on the other,
severally agree to pay to the Agent forthwith on demand

                                       29
<PAGE>

such corresponding amount, together with interest thereon for each day from the
date such amount is made available to the Borrower until the date such amount is
repaid to the Agent, (i) in the case of such Lender, at the Federal Funds Rate,
and (ii) in the case of the Borrower, at the rate of interest applicable at such
time to the Type of Loans comprising such Borrowing, as determined under the
provisions of Section 2.8. If such Lender shall repay to the Agent such
corresponding amount, such amount shall constitute such Lender's Loan as part of
such Borrowing for purposes of this Agreement. The failure of any Lender to make
any Loan required to be made by it as part of any Borrowing shall not relieve
any other Lender of its obligation, if any, hereunder to make its Loan as part
of such Borrowing, but no Lender shall be responsible for the failure of any
other Lender to make the Loan to be made by such other Lender as part of any
Borrowing.

     (c) Each Lender may, at its option, make and maintain any Loan at, to or
for the account of any of its Lending Offices, provided that any exercise of
                                               --------
such option shall not affect the obligation of the Borrower to repay such Loan
to or for the account of such Lender in accordance with the terms of this
Agreement.

     2.4  Notes.
          -----

     (a) The Loans made by each Lender shall be evidenced (i) in the case of
Revolving Loans, by a Revolving Note appropriately completed in substantially
the form of Exhibit A-1, and (ii) in the case of the Swingline Loans, by a
Swingline Note appropriately completed in substantially the form of Exhibit A-2.

     (b) Each Revolving Note issued to a Lender shall (i) be executed by the
Borrower, (ii) be payable to the order of such Lender, (iii) be dated as of the
Closing Date (or, in the case of a Revolving Note issued after the Closing Date,
dated the effective date of the applicable Assignment and Acceptance), (iv) be
in a stated principal amount equal to such Lender's Revolving Credit Commitment,
(v) bear interest in accordance with the provisions of Section 2.8, as the same
may be applicable from time to time to the Revolving Loans made by such Lender,
and (vi) be entitled to all of the benefits of this Agreement and the other
Credit Documents and subject to the provisions hereof and thereof.

     (c) The Swingline Note shall (i) be executed by the Borrower, (ii) be
payable to the order of the Swingline Lender, (iii) be dated as of the Closing
Date, (iv) be in a stated principal amount equal to the Swingline Commitment,
(v) bear interest in accordance with the provisions of Section 2.8, as the same
may be applicable from time to time to the Swingline Loans, and (vi) be entitled
to all of the benefits of this Agreement and the other Credit Documents and
subject to the provisions hereof and thereof.

     (d) Each Lender will record on its internal records the amount and Type of
each Loan made by it and each payment received by it in respect thereof and
will, in the event of any transfer of any of its Notes, either endorse on the
reverse side thereof or on a schedule attached thereto (or any continuation
thereof) the outstanding principal amount and Type of the Loans evidenced
thereby as of the date of transfer or provide such information on a schedule to
the Assignment and Acceptance relating to such transfer; provided, however, that
                                                         --------- --------
the failure of any

                                       30
<PAGE>

Lender to make any such recordation or provide any such information, or any
error therein, shall not affect the Borrower's obligations under this Agreement
or the Notes.

     2.5  Termination and Reduction of Commitments.
          -----------------------------------------

     (a) The Revolving Credit Commitments and Swingline Commitments shall be
terminated as follows:

          (i) The Revolving Credit Commitments shall be automatically and
     permanently terminated on the Termination Date; and

          (ii) The Swingline Commitment shall be automatically and permanently
     terminated on the Swingline Maturity Date.

     (b) At any time and from time to time after the date hereof, upon not less
than five (5) Business Days' prior written notice to the Agent (and, in the case
of a termination or reduction of the Unutilized Swingline Commitment, the
Swingline Lender), the Borrower may terminate in whole or reduce in part the
aggregate Unutilized Revolving Credit Commitments or the Unutilized Swingline
Commitment, provided that any such partial reduction shall be in an aggregate
            --------
amount of not less than $5,000,000 ($1,000,000 in the case of the Unutilized
Swingline Commitment) or, if greater, an integral multiple of $1,000,000 in
excess thereof ($500,000 in the case of the Unutilized Swingline Commitment).
The amount of any termination or reduction made under this Section 2.5(b) may
not thereafter be reinstated.

     (c) Each reduction of the Revolving Credit Commitments pursuant to this
Section 2.5 shall be applied ratably among the Revolving Credit Lenders
according to their respective Revolving Credit Commitments. Notwithstanding any
provision of this Agreement to the contrary, any reduction of the Revolving
Credit Commitments pursuant to this Section 2.5 that has the effect of reducing
the aggregate Revolving Credit Commitments to an amount less than the amount of
the Swingline Commitment at such time shall result in an automatic corresponding
reduction of the Swingline Commitment to the amount of the aggregate Revolving
Credit Commitments (as so reduced), without any further action on the part of
the Borrower or the Swingline Lender.

     2.6  Mandatory Payments and Prepayments.
          -----------------------------------

     (a) Except to the extent due or paid sooner pursuant to the provisions of
this Agreement, (i) the aggregate outstanding principal of the Revolving Loans
shall be due and payable in full on the Maturity Date, and (ii) the aggregate
outstanding principal of the Swingline Loans shall be due and payable in full on
the Swingline Maturity Date.

     (b) In the event that, at any time, the sum of (i) the aggregate principal
amount of Revolving Loans outstanding at such time, (ii) the aggregate Letter of
Credit Exposure of all Lenders at such time and (iii) the aggregate principal
amount of Swingline Loans outstanding at such time (excluding the aggregate
amount of any Swingline Loans to be repaid with proceeds of Revolving Loans made
on the date of determination) shall exceed the aggregate Revolving Credit
Commitments at such time (after giving effect to any concurrent termination or
reduction thereof), the Borrower shall, within two (2) Business Days after such
time, prepay the

                                       31
<PAGE>

outstanding principal amount of the Swingline Loans and, to the extent of any
excess remaining after prepayment in full of outstanding Swingline Loans, the
outstanding principal amount of the Revolving Loans, in the amount of such
excess; provided that, to the extent such excess amount is greater than the
        --------
aggregate principal amount of Swingline Loans and Revolving Loans outstanding
immediately prior to the application of such prepayment, the amount so prepaid
shall be retained by the Agent and held in the Cash Collateral Account as cover
for Letter of Credit Exposure, as more particularly described in Section 3.8,
and thereupon such cash shall be deemed to reduce the aggregate Letter of Credit
Exposure by an equivalent amount.

     (c) Promptly upon (and in any event not later than two (2) Business Days
after) its receipt thereof, the Borrower will prepay the outstanding principal
amount of the Loans in an amount equal to 50% of the Net Cash Proceeds from any
Equity Issuance (but only to the extent such net cash proceeds exceed $2,000,000
in aggregate in any fiscal year) and 100% of the Net Cash Proceeds from any Debt
Issuance, and will deliver to the Agent, concurrently with such prepayment, a
certificate signed by a Financial Officer of the Borrower in form and substance
satisfactory to the Agent and setting forth the calculation of such Net Cash
Proceeds.

     (d) Not later than one hundred-eighty (180) days after its receipt of any
proceeds of insurance, condemnation award or other compensation in respect of
any Casualty Event (or, if earlier, upon its determination not to repair or
replace any property subject to such Casualty Event), the Borrower will prepay
the outstanding principal amount of the Loans in an amount equal to 100% of the
Net Cash Proceeds from such Casualty Event (less any amounts theretofore applied
(or committed to be applied) to the repair or replacement of property subject to
such Casualty Event) and will deliver to the Agent, concurrently with such
prepayment, a certificate signed by a Financial Officer of the Borrower in form
and substance satisfactory to the Agent and setting forth the calculation of
such Net Cash Proceeds; provided, however, that, notwithstanding the foregoing,
                        --------- --------
(i) nothing in this Section 2.6(d) shall be deemed to limit or otherwise affect
any right of the Agent herein or in any of the other Credit Documents to receive
and hold such proceeds as loss payee and to disburse the same to the Borrower
upon the terms hereof or thereof, or any obligation of the Borrower or any of
its Subsidiaries herein or in any of the other Credit Documents to remit any
such proceeds to the Agent upon its receipt thereof, and (ii) any and all such
proceeds received or held by the Agent or the Borrower or any of its
Subsidiaries during the continuance of an Event of Default (regardless of any
proposed or actual use thereof for repair or replacement) shall be applied to
prepay the outstanding principal amount of the Loans.

     (e) Promptly upon (and in any event not later than two (2) Business Days
after) its receipt thereof, the Borrower will prepay the outstanding principal
amount of the Loans in an amount equal to 100% of the Net Cash Proceeds from any
Asset Disposition and will deliver to the Agent, concurrently with such
prepayment, a certificate signed by a Financial Officer of the Borrower in form
and substance satisfactory to the Agent and setting forth the calculation of
such Net Cash Proceeds.

     (f) Concurrently with the delivery of its annual financial statements after
the end of each fiscal year, beginning with the fiscal year ending December 31,
2002, and in any event not later than ninety (90) days after the last day of
each such fiscal year, the Borrower will prepay the outstanding principal amount
of the Loans in an amount equal to 50% of Excess Cash Flow,

                                       32
<PAGE>

if any, for such fiscal year; provided, however that so long as the Borrower's
                              --------- -------
Leverage Ratio is equal to or less than 1.5 to 1.0 as of the last day of such
fiscal year, no Excess Cash Flow prepayment shall be required under this Section
2.6(f) for such fiscal year. The Borrower will deliver to the Agent,
concurrently with each such prepayment (or by the date that a prepayment would
have been due), a certificate signed by a Financial Officer of the Borrower in
form and substance satisfactory to the Agent and setting forth the calculation
of such Excess Cash Flow or, as applicable, the Leverage Ratio.

     (g) Each prepayment of the Loans made pursuant to Sections 2.6(c) through
2.6(f) shall be applied to reduce the outstanding principal amount of the
Revolving Loans (but without reduction of the Revolving Loan Commitments). If
excess funds remain after application of the prepayments in accordance with the
foregoing sentence, and no Default or Event of Default has occurred and is
continuing, then such excess funds shall be returned to or retained by the
Borrower. Each payment or prepayment pursuant to the provisions of this Section
2.6 shall be applied ratably among the Lenders holding the Loans being prepaid,
in proportion to the principal amount held by each. Revolving Loans prepaid
pursuant to this Sections 2.6(c) through 2.6(g) may be reborrowed, subject to
the terms and conditions of this Agreement.

     (h) The Borrower shall deliver to the Agent and each Lender, to the extent
practicable, at least one (1) Business Days' prior written notice of any
prepayment pursuant to Sections 2.6(c) through 2.6(g).

     (i) Each payment or prepayment of a LIBOR Loan made pursuant to the
provisions of this Section 2.6 on a day other than the last day of the Interest
Period applicable thereto shall be made together with all amounts required under
Section 2.18 to be paid as a consequence thereof; provided, that for prepayments
                                                  ---------
of LIBOR Loans required pursuant to Sections 2.6(c) through 2.6(f) on a date
other than the last day of the Interest Period with respect thereto, at the
Borrower's option, the amount of such prepayment (after application to any Base
Rate Loans) shall be deposited with the Agent as cash collateral for the LIBOR
Loans on terms reasonably satisfactory to the Agent and thereafter shall be
applied in the order of the Interest Periods next ending most closely to the
date such prepayment is required to be made and on the last day of each such
Interest Period. After such application, unless an Event of Default shall have
occurred and be continuing (in which case such interest shall be held as cash
collateral or applied by the Agent to any Obligations then due and payable), any
remaining interest earned on such cash collateral shall be paid to Borrower.

     (j) Notwithstanding the foregoing, nothing in this Section 2.6 shall be
deemed to permit any Equity Issuance, Debt Issuance or Asset Disposition not
expressly permitted under Article VII or Article VIII.

     2.7  Voluntary Prepayments.
          ----------------------

     (a) At any time and from time to time, the Borrower shall have the right to
prepay the Loans, in whole or in part, without premium or penalty (except as
provided in clause (iii) below), upon written notice given to the Agent not
later than 12:00 noon (Charlotte, North Carolina time) three (3) Business Days
prior to each intended prepayment of LIBOR Loans and on the same Business Day of
each intended prepayment of Base Rate Loans (including Swingline Loans),

                                       33
<PAGE>

provided that (i) each partial prepayment shall be in an aggregate principal
amount of not less than $1,000,000 or, if greater, an integral multiple of
$1,000,000 in excess thereof for LIBOR Loans and $500,000 in excess thereof for
Base Rate Loans ($1,000,000 and $500,000, respectively, in the case of Swingline
Loans), (ii) no partial prepayment of LIBOR Loans made pursuant to any single
Borrowing shall reduce the aggregate outstanding principal amount of the
remaining LIBOR Loans under such Borrowing to less than $3,000,000 or to any
greater amount not an integral multiple of $1,000,000 in excess thereof, and
(iii) unless made together with all amounts required under Section 2.18 to be
paid as a consequence of such prepayment, a prepayment of a LIBOR Loan may be
made only on the last day of the Interest Period applicable thereto. Each such
notice shall specify the proposed date of such prepayment and the aggregate
principal amount and Type of the Loans to be prepaid (and, in the case of LIBOR
Loans, the Interest Period of the Borrowing pursuant to which made), and shall
be irrevocable and shall bind the Borrower to make such prepayment on the terms
specified therein. Revolving Loans and Swingline Loans prepaid pursuant to this
Section 2.7(a) may be reborrowed, subject to the terms and conditions of this
Agreement.

     2.8  Interest.
          --------

     (a) The Borrower will pay interest in respect of the unpaid principal
amount of each Loan, from the date of Borrowing thereof until such principal
amount shall be paid in full, (i) at the Adjusted Base Rate as in effect from
time to time during such periods as such Loan is a Base Rate Loan, or (ii) at
the Adjusted LIBOR Rate as in effect from time to time during such periods as
such Loan is a LIBOR Loan.

     (b) Upon the occurrence and during the continuance of any Event of Default
under Section 9.1(a), hereof and (at the election of the Required Lenders) upon
the occurrence and during the continuance of any other Event of Default, all
outstanding principal amounts of the Loans and, to the greatest extent permitted
by law, all interest accrued on the Loans and all other accrued and outstanding
fees and other amounts hereunder, shall bear interest at a rate per annum equal
to the interest rate applicable from time to time thereafter to such Loans
(whether the Adjusted Base Rate or the Adjusted LIBOR Rate) plus 2% (or, in the
case of fees and other amounts, at the Adjusted Base Rate plus 2%), and, in each
case, such default interest shall be payable on demand. To the greatest extent
permitted by law, interest shall continue to accrue after the filing by or
against the Borrower of any petition seeking any relief in bankruptcy or under
any law pertaining to insolvency or debtor relief.

     (c) Accrued (and theretofore unpaid) interest shall be payable as follows:

          (i) in respect of each Base Rate Loan (including any Base Rate Loan or
     portion thereof paid or prepaid pursuant to the provisions of Section 2.6,
     except as provided hereinbelow), in arrears on the last Business Day of
     each calendar quarter, beginning with the first such day to occur after the
     Closing Date; provided, that in the event the Loans are repaid or prepaid
                   ---------
     in full and the Revolving Credit Commitments have been terminated, then
     accrued interest in respect of all Base Rate Loans shall be payable
     together with such repayment or prepayment on the date thereof;

                                       34
<PAGE>

          (ii) in respect of each LIBOR Loan (including any LIBOR Loan or
     portion thereof paid or prepaid pursuant to the provisions of Section 2.6,
     except as provided hereinbelow), in arrears (y) on the last Business Day of
     the Interest Period applicable thereto (subject to the provisions of
     Section 2.10(iv)) and (z) in addition, in the case of a LIBOR Loan with an
     Interest Period having a duration of six months or longer, on each date on
     which interest would have been payable under clause (y) above had
     successive Interest Periods of three months' duration been applicable to
     such LIBOR Loan; provided, that in the event all -------- LIBOR Loans made
     pursuant to a single Borrowing are repaid or prepaid in full, then accrued
     interest in respect of such LIBOR Loans shall be payable together with such
     repayment or prepayment on the date thereof; and

          (iii) in respect of any Loan, at maturity (whether pursuant to
     acceleration or otherwise) and, after maturity, on demand.

     (d) Nothing contained in this Agreement or in any other Credit Document
shall be deemed to establish or require the payment of interest to any Lender at
a rate in excess of the maximum rate permitted by applicable law. If the amount
of interest payable for the account of any Lender on any interest payment date
would exceed the maximum amount permitted by applicable law to be charged by
such Lender, the amount of interest payable for its account on such interest
payment date shall be automatically reduced to such maximum permissible amount.
In the event of any such reduction affecting any Lender, if from time to time
thereafter the amount of interest payable for the account of such Lender on any
interest payment date would be less than the maximum amount permitted by
applicable law to be charged by such Lender, then the amount of interest payable
for its account on such subsequent interest payment date shall be automatically
increased to such maximum permissible amount, provided that at no time shall the
aggregate amount by which interest paid for the account of any Lender has been
increased pursuant to this sentence exceed the aggregate amount by which
interest paid for its account has theretofore been reduced pursuant to the
previous sentence.

     (e) The Agent shall promptly notify the Borrower and the Lenders upon
determining the interest rate for each Borrowing of LIBOR Loans after its
receipt of the relevant Notice of Borrowing or Notice of
Conversion/Continuation, and upon each change in the Base Rate; provided,
                                                                ---------
however, that the failure of the Agent to provide the Borrower or the Lenders
--------
with any such notice shall neither affect any obligations of the Borrower or the
Lenders hereunder nor result in any liability on the part of the Agent to the
Borrower or any Lender. Each such determination (including each determination of
the Reserve Requirement) shall, absent manifest error, be conclusive and binding
on all parties hereto.

     2.9  Fees. The Borrower agrees to pay:
          ----

     (a) To the Agent, for the account of each Revolving Credit Lender, a
commitment fee for each calendar quarter (or portion thereof) for the period
from the date of this Agreement to the Termination Date, at a per annum rate
equal to the Applicable Margin Percentage in effect for such fee from time to
time during such quarter on such Lender's ratable share (based on the proportion
that its Revolving Credit Commitment bears to the aggregate Revolving Credit
Commitments) of the average daily aggregate Unutilized Revolving Credit
Commitments,

                                       35
<PAGE>

payable in arrears (i) on the last Business Day of each calendar quarter,
beginning with the first such day to occur after the Closing Date, and (ii) on
the Termination Date;

     (b) To the Agent, for the account of each Revolving Credit Lender, a letter
of credit fee for each calendar quarter (or portion thereof) in respect of all
Letters of Credit outstanding during such quarter, at a per annum rate equal to
the Applicable Margin Percentage in effect from time to time during such quarter
for Revolving Loans that are maintained as LIBOR Loans, on such Lender's ratable
share (based on the proportion that its Revolving Credit Commitment bears to the
aggregate Revolving Credit Commitments) of the daily average aggregate Stated
Amount of such Letters of Credit, payable in arrears (i) on the last Business
Day of each calendar quarter, beginning with the first such day to occur after
the Closing Date, and (ii) on the later of the Termination Date and the date of
termination of the last outstanding Letter of Credit;

     (c) To the Issuing Lender for its own account, a facing fee for each
calendar quarter (or portion thereof) in respect of all Letters of Credit
outstanding during such quarter, at a per annum rate of 0.125% on the daily
average aggregate Stated Amount of such Letters of Credit (provided, however,
                                                           --------- --------
that, notwithstanding the foregoing, the annual amount of such fee with regard
to any single Letter of Credit shall not be less than $2,000), payable in
arrears (i) on the last Business Day of each calendar quarter, beginning with
the first such day to occur after the Closing Date, and (ii )on the later of the
Termination Date and the date of termination of the last outstanding Letter of
Credit;

     (d) To the Issuing Lender, for its own account, such commissions, issuance
fees, transfer fees and other fees and charges incurred in connection with the
issuance and administration of each Letter of Credit as are customarily charged
from time to time by the Issuing Lender for the performance of such services in
connection with similar letters of credit, or as may be otherwise agreed to by
the Issuing Lender, but without duplication of amounts payable under Section
2.9(h); and

     (e) To the Agent, for its own account, the annual administrative fee
described in the Fee Letter, on the terms, in the amount and at the times set
forth therein.

     2.10 Interest Periods. Concurrently with the giving of a Notice of
          ----------------
Borrowing or Notice of Conversion/Continuation in respect of any Borrowing
comprised of Base Rate Loans to be converted into, or LIBOR Loans to be
continued as, LIBOR Loans, the Borrower shall have the right to elect, pursuant
to such notice, the interest period (each, an "Interest Period") to be
applicable to such LIBOR Loans, which Interest Period shall, at the option of
the Borrower, be a one, two, three or six-month period; provided, however, that:
                                                        --------- --------

          (i) all LIBOR Loans comprising a single Borrowing shall at all times
     have the same Interest Period;

          (ii) the initial Interest Period for any LIBOR Loan shall commence on
     the date of the Borrowing of such LIBOR Loan (including the date of any
     continuation of, or conversion into, such LIBOR Loan), and each successive
     Interest Period applicable to such LIBOR Loan shall commence on the day on
     which the next preceding Interest Period applicable thereto expires;

                                       36
<PAGE>

          (iii) LIBOR Loans may not be outstanding under more than seven (7)
     separate Interest Periods at any one time (for which purpose Interest
     Periods shall be deemed to be separate even if they are coterminous);

          (iv) if any Interest Period otherwise would expire on a day that is
     not a Business Day, such Interest Period shall expire on the next
     succeeding Business Day unless such next succeeding Business Day falls in
     another calendar month, in which case such Interest Period shall expire on
     the next preceding Business Day;

          (v) the Borrower may not select any Interest Period that begins prior
     to the third (3rd) Business Day after the Closing Date or that expires
     after the Maturity Date;

          (vi) the Borrower may not select an Interest Period having a duration
     longer than one month at any time prior to the 90th day after the Closing
     Date;

          (vii) if any Interest Period begins on a day for which there is no
     numerically corresponding day in the calendar month during which such
     Interest Period would otherwise expire, such Interest Period shall expire
     on the last Business Day of such calendar month; and

          (viii) the Borrower may not select any Interest Period (and
     consequently, no LIBOR Loans shall be made) if a Default or Event of
     Default shall have occurred and be continuing at the time of such Notice of
     Borrowing or Notice of Conversion/Continuation with respect to any
     Borrowing.

     2.11 Conversions and Continuations.
          -----------------------------

     (a) The Borrower shall have the right, on any Business Day occurring on or
after the Closing Date, to elect (i) to convert all or a portion of the
outstanding principal amount of any Base Rate Loans into LIBOR Loans, or to
convert any LIBOR Loans the Interest Periods for which end on the same day into
Base Rate Loans, or (ii) upon the expiration of any Interest Period, to continue
all or a portion of the outstanding principal amount of any LIBOR Loans the
Interest Periods for which end on the same day for an additional Interest
Period, provided that (w) any such conversion of LIBOR Loans into Base Rate
        --------
Loans shall involve an aggregate principal amount of not less than $1,000,000
or, if greater, an integral multiple of $500,000 in excess thereof; any such
conversion of Base Rate Loans into, or continuation of, LIBOR Loans shall
involve an aggregate principal amount of not less than $3,000,000 or, if
greater, an integral multiple of $1,000,000 in excess thereof; and no partial
conversion of LIBOR Loans made pursuant to a single Borrowing shall reduce the
outstanding principal amount of such LIBOR Loans to less than $3,000,000 or to
any greater amount not an integral multiple of $1,000,000 in excess thereof, (x)
except as otherwise provided in Section 2.16(d), LIBOR Loans may be converted
into Base Rate Loans only on the last day of the Interest Period applicable
thereto (and, in any event, if a LIBOR Loan is converted into a Base Rate Loan
on any day other than the last day of the Interest Period applicable thereto,
the Borrower will pay, upon such conversion, all amounts required under Section
2.18 to be paid as a consequence thereof), (y) no such conversion or
continuation shall be permitted with regard to any Base Rate Loans that are

                                       37
<PAGE>

Swingline Loans, and (z) no conversion of Base Rate Loans into LIBOR Loans or
continuation of LIBOR Loans shall be permitted during the continuance of a
Default or Event of Default.

     (b) The Borrower shall make each such election by giving the Agent written
notice not later than 12:00 p.m. noon (Charlotte, North Carolina time) three (3)
Business Days prior to the intended effective date of any conversion of Base
Rate Loans into, or continuation of, LIBOR Loans and on the same Business Day as
the intended effective date of any conversion of LIBOR Loans into Base Rate
Loans. Each such notice (each, a "Notice of Conversion/Continuation") shall be
irrevocable, shall be given in the form of Exhibit B-3 and shall specify (x) the
date of such conversion or continuation (which shall be a Business Day), (y) in
the case of a conversion into, or a continuation of, LIBOR Loans, the Interest
Period to be applicable thereto, and (z) the aggregate amount and Type of the
Loans being converted or continued. Upon the receipt of a Notice of
Conversion/Continuation, the Agent will promptly notify each Lender of the
proposed conversion or continuation. In the event that the Borrower shall fail
to deliver a Notice of Conversion/Continuation as provided herein with respect
to any outstanding LIBOR Loans, such LIBOR Loans shall automatically be
converted to Base Rate Loans upon the expiration of the then current Interest
Period applicable thereto (unless repaid pursuant to the terms hereof). In the
event the Borrower shall have failed to select in a Notice of
Conversion/Continuation the duration of the Interest Period to be applicable to
any conversion into, or continuation of, LIBOR Loans, then the Borrower shall be
deemed to have selected an Interest Period with a duration of one month.

     2.12 Method of Payments; Computations.
          --------------------------------

     (a) All payments by the Borrower hereunder shall be made without setoff,
counterclaim or other defense, in Dollars and in immediately available funds to
the Agent, for the account of the Lenders entitled to such payment or the
Swingline Lender, as the case may be (except as otherwise expressly provided
herein as to payments required to be made directly to the Issuing Lender or the
Lenders) at its office referred to in Section 11.5 (or at such other location as
the Agent may designate) prior to 12:00 noon (Charlotte, North Carolina time) on
the date payment is due. Any payment made as required hereinabove, but after
12:00 noon (Charlotte, North Carolina time) shall be deemed to have been made on
the next succeeding Business Day. If any payment falls due on a day that is not
a Business Day, then such due date shall be extended to the next succeeding
Business Day (except that in the case of LIBOR Loans to which the provisions of
Section 2.10(iv) are applicable, such due date shall be the next preceding
Business Day), and such extension of time shall then be included in the
computation of payment of interest, fees or other applicable amounts.

     (b) The Agent will distribute to the Lenders like amounts relating to
payments made to the Agent for the account of the Lenders as follows: (i) if the
payment is received by 12:00 noon (Charlotte, North Carolina time) in
immediately available funds, the Agent will make available to each relevant
Lender on the same date, by wire transfer of immediately available funds, such
Lender's ratable share of such payment (based on the percentage that the amount
of the relevant payment owing to such Lender bears to the total amount of such
payment owing to all of the relevant Lenders), and (ii) if such payment is
received after 12:00 noon (Charlotte, North Carolina time) or in other than
immediately available funds, the Agent will make available to each such Lender
its ratable share of such payment by wire transfer of immediately available

                                       38
<PAGE>

funds on the next succeeding Business Day (or in the case of uncollected funds,
as soon as practicable after collected). If the Agent shall not have made a
required distribution to the appropriate Lenders as required hereinabove after
receiving a payment for the account of such Lenders, the Agent will pay to each
such Lender, on demand, its ratable share of such payment with interest thereon
at the Federal Funds Rate for each day from the date such amount was required to
be disbursed by the Agent until the date repaid to such Lender. The Agent will
distribute to the Issuing Lender like amounts relating to payments made to the
Agent for the account of the Issuing Lender in the same manner, and subject to
the same terms and conditions, as set forth hereinabove with respect to
distributions of amounts to the Lenders.

     (c) Unless the Agent shall have received written notice from the Borrower
prior to the date on which any payment is due to any Lender hereunder that such
payment will not be made in full, the Agent may assume that the Borrower has
made such payment in full to the Agent on such date, and the Agent may, in
reliance on such assumption, but shall not be obligated to, cause to be
distributed to such Lender on such due date an amount equal to the amount then
due to such Lender. If and to the extent the Borrower shall not have so made
such payment in full to the Agent, and without limiting the obligation of the
Borrower to make such payment in accordance with the terms hereof, such Lender
shall repay to the Agent forthwith on demand such amount so distributed to such
Lender, together with interest thereon for each day from the date such amount is
so distributed to such Lender until the date repaid to the Agent, at the Federal
Funds Rate.

     (d) All computations of interest and fees hereunder (including computations
of the Reserve Requirement) shall be made on the basis of a year consisting of
(i) in the case of interest on Base Rate Loans, 365/366 days, as the case may
be, or (ii) in all other instances, 360 days; and in each case under (i) and
(ii) above, with regard to the actual number of days (including the first day,
but excluding the last day) elapsed.

     2.13 Recovery of Payments.
          --------------------

     (a) The Borrower agrees that to the extent the Borrower makes a payment or
payments to or for the account of the Agent, the Swingline Lender, any Lender or
the Issuing Lender, which payment or payments or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required to be repaid to a trustee, receiver or any other party under any
bankruptcy, insolvency or similar state or federal law, common law or equitable
cause, then, to the extent of such payment or repayment, the Obligation intended
to be satisfied shall be revived and continued in full force and effect as if
such payment had not been received.

     (b) If any amounts distributed by the Agent to any Lender are subsequently
returned or repaid by the Agent to the Borrower or its representative or
successor in interest, whether by court order or by settlement approved by the
Lender in question, such Lender will, promptly upon receipt of notice thereof
from the Agent, pay the Agent such amount. If any such amounts are recovered by
the Agent from the Borrower or its representative or successor in interest, the
Agent will redistribute such amounts to the Lenders on the same basis as such
amounts were originally distributed.

                                       39
<PAGE>

     2.14 Use of Proceeds. The proceeds of the Loans shall be used (i) first, to
          ---------------
repay the Terminating Senior Indebtedness in full, (ii) second, to pay or
reimburse reasonable transaction fees and expenses in connection with the
closing of the transactions contemplated hereby, and (iii) thereafter, for
working capital and general business purposes and in accordance with the terms
and provisions of this Agreement.

     2.15 Pro Rata Treatment.
          ------------------

     (a) Except in the case of Swingline Loans, all fundings, continuations and
conversions of Loans shall be made by the Lenders pro rata on the basis of their
respective Revolving Credit Commitments (in the case of the initial funding of
Loans pursuant to Section 2.2) or on the basis of their respective outstanding
Loans (in the case of continuations and conversions of Loans pursuant to Section
2.11, and additionally in all cases in the event the Revolving Credit
Commitments have expired or have been terminated), as the case may be from time
to time. All payments on account of principal of or interest on any Loans, fees
or any other Obligations owing to or for the account of any one or more Lenders
shall be apportioned ratably among such Lenders in proportion to the amounts of
such principal, interest, fees or other Obligations owed to them respectively.

     (b) Each Lender agrees that if it shall receive any amount hereunder
(whether by voluntary payment, realization upon security, exercise of the right
of setoff or banker's lien, counterclaim or cross action, or otherwise), other
than pursuant to Section 11.7, applicable to the payment of any of the
Obligations that exceeds its ratable share (according to the proportion of (i)
the amount of such Obligations due and payable to such Lender at such time to
(ii) the aggregate amount of such Obligations due and payable to all Lenders at
such time) of payments on account of such Obligations then or therewith obtained
by all the Lenders to which such payments are required to have been made, such
Lender shall forthwith purchase from the other Lenders such participations in
such Obligations as shall be necessary to cause such purchasing Lender to share
the excess payment or other recovery ratably with each of them; provided,
                                                                ---------
however, that if all or any portion of such excess payment is thereafter
--------
recovered from such purchasing Lender, such purchase from each such other Lender
shall be rescinded and each such other Lender shall repay to the purchasing
Lender the purchase price to the extent of such recovery, together with an
amount equal to such other Lender's ratable share (according to the proportion
of (i) the amount of such other Lender's required repayment to (ii) the total
amount so recovered from the purchasing Lender) of any interest or other amount
paid or payable by the purchasing Lender in respect of the total amount so
recovered. The Borrower agrees that any Lender so purchasing a participation
from another Lender pursuant to the provisions of this Section 2.15(b) may, to
the fullest extent permitted by law, exercise any and all rights of payment
(including, without limitation, setoff, banker's lien or counterclaim) with
respect to such participation as fully as if such participant were a direct
creditor of the Borrower in the amount of such participation. If under any
applicable bankruptcy, insolvency or similar law, any Lender receives a secured
claim in lieu of a setoff to which this Section 2.15(b) applies, such Lender
shall, to the extent practicable, exercise its rights in respect of such secured
claim in a manner consistent with the rights of the Lenders entitled under this
Section 2.15(b) to share in the benefits of any recovery on such secured claim.

     2.16 Increased Costs; Change in Circumstances; Illegality; etc.
          ----------------------------------------------------------

                                       40
<PAGE>

     (a) If the introduction of or any change in any applicable law, rule or
regulation or in the interpretation or administration thereof by any
Governmental Authority charged with the interpretation or administration
thereof, in each case after the date hereof, or compliance by any Lender with
any guideline or request from any such Governmental Authority (whether or not
having the force of law) given or made after the date hereof, shall (i) subject
such Lender to any tax or other charge, or change the basis of taxation of
payments to such Lender, in respect of any of its LIBOR Loans or any other
amounts payable hereunder or its obligation to make, fund or maintain any LIBOR
Loans (other than any change in the rate or basis of tax on the overall net
income or profits of, or any branch or franchise tax applicable to, such Lender
or its applicable Lending Office), (ii) impose, modify or deem applicable any
reserve, special deposit or similar requirement (but excluding any reserves to
the extent actually included within the Reserve Requirement in the calculation
of the LIBOR Rate) against assets of, deposits with or for the account of, or
credit extended by, such Lender or its applicable Lending Office, or (iii)
impose on such Lender or its applicable Lending Office any other condition, and
the result of any of the foregoing shall be to increase the cost to such Lender
of making or maintaining any LIBOR Loans or issuing or participating in Letters
of Credit or to reduce the amount of any sum received or receivable by such
Lender hereunder (including in respect of Letters of Credit), the Borrower will,
promptly upon written demand therefor by such Lender, (but in no event more than
15 days after delivery of such written demand), pay to such Lender such
additional amounts as shall compensate such Lender for such increase in costs or
reduction in return.

     (b) If any Lender shall have reasonably determined that the introduction of
or any change in any applicable law, rule or regulation regarding capital
adequacy or in the interpretation or administration thereof by any Governmental
Authority charged with the interpretation or administration thereof, in each
case after the date hereof, or compliance by such Lender with any guideline or
request from any such Governmental Authority (whether or not having the force of
law) given or made after the date hereof, has or would have the effect, as a
consequence of such Lender's Revolving Credit Commitment, Loans or issuance of
or participations in Letters of Credit hereunder, of reducing the rate of return
on the capital of such Lender or any Person controlling such Lender to a level
below that which such Lender or controlling Person could have achieved but for
such introduction, change or compliance (taking into account such Lender's or
controlling Person's policies with respect to capital adequacy), the Borrower
will, within fifteen (15) days of receipt of written demand therefor by such
Lender therefor, pay to such Lender such additional amounts as will compensate
such Lender or controlling Person for such reduction in return.

     (c) If, on or prior to the first day of any Interest Period, (i) the Agent
shall have determined that adequate and reasonable means do not exist for
ascertaining the applicable LIBOR Rate for such Interest Period or (ii) the
Agent shall have received written notice from the Required Lenders of their
determination that the rate of interest referred to in the definition of "LIBOR
Rate" upon the basis of which the Adjusted LIBOR Rate for LIBOR Loans for such
Interest Period is to be determined will not adequately and fairly reflect the
cost to such Lenders of making or maintaining LIBOR Loans during such Interest
Period, the Agent will forthwith so notify the Borrower and the Lenders in
writing. Upon such notice, (A) all then outstanding LIBOR Loans shall
automatically, on the expiration date of the respective Interest Periods
applicable thereto (unless then repaid in full), be converted into Base Rate
Loans, (B) the obligation of the Lenders to make, to convert Base Rate Loans
into, or to continue, LIBOR

                                       41
<PAGE>

Loans shall be suspended (including pursuant to the Borrowing to which such
Interest Period applies), and (C) any Notice of Borrowing or Notice of
Conversion/Continuation given at any time thereafter with respect to LIBOR Loans
shall be deemed to be a request for Base Rate Loans, in each case until the
Agent or the Required Lenders, as the case may be, shall have determined that
the circumstances giving rise to such suspension no longer exist (and the
Required Lenders, if making such determination, shall have so notified the
Agent), and the Agent shall have so notified the Borrower and the Lenders in
writing.

     (d) Notwithstanding any other provision in this Agreement, if, at any time
after the date hereof and from time to time, any Lender shall have determined in
good faith that the introduction of or any change in any applicable law, rule or
regulation or in the interpretation or administration thereof by any
Governmental Authority charged with the interpretation or administration
thereof, or compliance with any guideline or request from any such Governmental
Authority (whether or not having the force of law), has or would have the effect
of making it unlawful for such Lender to make or to continue to make or maintain
LIBOR Loans, such Lender will forthwith so notify the Agent and the Borrower in
writing. Upon such notice, (i) each of such Lender's then outstanding LIBOR
Loans shall automatically, on the expiration date of the respective Interest
Period applicable thereto (or, to the extent any such LIBOR Loan may not
lawfully be maintained as a LIBOR Loan until such expiration date, upon such
notice), be converted into a Base Rate Loan, (ii) the obligation of such Lender
to make, to convert Base Rate Loans into, or to continue, LIBOR Loans shall be
suspended (including pursuant to any Borrowing for which the Agent has received
a Notice of Borrowing but for which the Borrowing Date has not arrived), and
(iii) any Notice of Borrowing or Notice of Conversion/Continuation given at any
time thereafter with respect to LIBOR Loans shall, as to such Lender, be deemed
to be a request for a Base Rate Loan, in each case until such Lender shall have
determined that the circumstances giving rise to such suspension no longer exist
and shall have so notified the Agent, and the Agent shall have so notified the
Borrower in writing.

     (e) Determinations by the Agent or any Lender for purposes of this Section
2.16 of any increased costs, reduction in return, market contingencies,
illegality or any other matter shall, absent manifest error, be conclusive,
provided that such determinations are made in good faith. No failure by the
--------
Agent or any Lender at any time to demand payment of any amounts payable under
this Section 2.16 shall constitute a waiver of its right to demand payment of
any additional amounts arising at any subsequent time. Nothing in this Section
2.16 shall require or be construed to require the Borrower to pay any interest,
fees, costs or other amounts in excess of that permitted by applicable law.

     (f) Each Lender agrees that, upon the occurrence of any event giving rise
to the operation of this Section with respect to such Lender, it will, if
requested by the Borrower and to the extent permitted by law, endeavor in good
faith to designate another available Lending Office for its LIBOR Loans, but
only if such designation would make it lawful for such Lender to continue to
make or maintain LIBOR Loans hereunder, provided that no Lender shall be
required to make any such designation that in its good faith determination,
would result in increased cost or economic, legal or regulatory disadvantage.

     2.17 Taxes.
          ------

                                       42
<PAGE>

     (a) Any and all payments by the Borrower hereunder or under any Note shall
be made, in accordance with the terms hereof and thereof, free and clear of and
without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
excluding taxes imposed on, or measured by, the overall net income (or branch or
franchise taxes imposed in lieu thereof) of the Agent or any Lender by reason of
any present or former connection between the Agent or such Lender and the
jurisdiction of the Governmental Authority imposing such tax or any political
subdivision thereof, other than such a connection arising solely from the Agent
or such Lender having executed, delivered or performed its obligations or
received a payment under, or enforced, this Agreement or the Notes (all such
nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under any Note to the Agent or any Lender, (i) the sum payable
shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.17), the Agent or such Lender, as the case may be, receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower will make such deductions, (iii) the Borrower will pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law and (iv) the Borrower will deliver to the Agent
or such Lender, as the case may be, evidence of such payment.

     (b) The Borrower will indemnify the Agent and each Lender for the full
amount of Taxes (including, without limitation, any Taxes imposed by any
jurisdiction on amounts payable under this Section 2.17) paid by the Agent or
such Lender, as the case may be, and any liability (including penalties,
interest and expenses) arising therefrom or with respect thereto, whether or not
such Taxes were correctly or legally asserted. This indemnification shall be
made within 30 days from the date the Agent or such Lender, as the case may be,
makes written demand therefor.

     (c) Each of the Agent and the Lenders agrees that if it subsequently
recovers, or receives a permanent net tax benefit with respect to, any amount of
Taxes (i) previously paid by it and as to which it has been indemnified by or on
behalf of the Borrower or (ii) previously deducted by the Borrower (including,
without limitation, any Taxes deducted from any additional sums payable under
Section 2.17(a)(i)), the Agent or such Lender, as the case may be, shall
reimburse the Borrower to the extent of the amount of any such recovery or
permanent net tax benefit (but only to the extent of indemnity payments made, or
additional amounts paid, by or on behalf of the Borrower under this Section 2.17
with respect to the Taxes giving rise to such recovery or tax benefit);
provided, however, that the Borrower, upon the request of the Agent or such
--------  -------
Lender, agrees to repay to the Agent or such Lender, as the case may be, the
amount paid over to the Borrower (together with any penalties, interest or other
charges), in the event the Agent or such Lender is required to repay such amount
to the relevant taxing authority or other Governmental Authority. The
determination by the Agent or any Lender of the amount of any such recovery or
permanent net tax benefit shall be made in good faith and shall, in the absence
of manifest error, be conclusive and binding.

     (d) If any Lender is not a United States person (as such term is defined in
Section 7701(a)(30) of the Code) for federal income tax purposes (a "Non-U.S.
Lender") and is entitled to an exemption from or a reduction of United States
withholding tax pursuant to the Internal

                                       43
<PAGE>

Revenue Code, such Non-U.S. Lender will deliver to each of the Agent and the
Borrower, on or prior to the Closing Date (or, in the case of a Non-U.S. Lender
that becomes a party to this Agreement as a result of an assignment after the
Closing Date, on the effective date of such assignment), (i) in the case of a
Non-U.S. Lender that is a "bank" for purposes of Section 881(c)(3)(A) of the
Internal Revenue Code, a properly completed Internal Revenue Service Form
W-8BEN, W-8ECI or W-8EXP, as applicable (or successor forms), certifying that
such Non-U.S. Lender is entitled to an exemption from or a reduction of
withholding or deduction for or on account of United States federal income taxes
in connection with payments under this Agreement or any of the Notes, together
with a properly completed Internal Revenue Service Form W-8 or W-9, as
applicable (or successor forms), and (ii) in the case of a Non-U.S. Lender that
is not a "bank" for purposes of Section 881(c)(3)(A) of the Internal Revenue
Code, a certificate in form and substance reasonably satisfactory to the Agent
and the Borrower and to the effect that (x) such Non-U.S. Lender is not a "bank"
for purposes of Section 881(c)(3)(A) of the Internal Revenue Code, is not
subject to regulatory or other legal requirements as a bank in any jurisdiction,
and has not been treated as a bank for purposes of any tax, securities law or
other filing or submission made to any governmental authority, any application
made to a rating agency or qualification for any exemption from any tax,
securities law or other legal requirements, (y) is not a ten (10) percent
shareholder for purposes of Section 881(c)(3)(B) of the Internal Revenue Code
and (z) is not a controlled foreign corporation receiving interest from a
related person for purposes of Section 881(c)(3)(C) of the Internal Revenue
Code, together with a properly completed Internal Revenue Service Form W-8 or
W-9, as applicable (or successor forms). Each such Non-U.S. Lender further
agrees to deliver to each of the Agent and the Borrower an additional copy of
each such relevant form on or before the date that such form expires or becomes
obsolete or after the occurrence of any event (including a change in its
applicable Lending Office) requiring a change in the most recent forms so
delivered by it, in each case certifying that such Non-U.S. Lender is entitled
to an exemption from or a reduction of withholding or deduction for or on
account of United States federal income taxes in connection with payments under
this Agreement or any of the Notes, unless an event (including, without
limitation, any change in treaty, law or regulation) has occurred prior to the
date on which any such delivery would otherwise be required, which event renders
all such forms inapplicable or the exemption or reduction to which such forms
relate unavailable and such Non-U.S. Lender notifies the Agent and the Borrower
that it is not entitled to receive payments without or at a reduced rate of
deduction or withholding of United States federal income taxes. Each such
Non-U.S. Lender will promptly notify the Agent and the Borrower of any changes
in circumstances that would modify or render invalid any claimed exemption or
reduction.

     (e) The Borrower shall not be required to indemnify any Non-U.S. Lender, or
to pay any additional amounts to any Non-U.S. Lender, in respect of United
States federal withholding tax to the extent that (i) the obligation to pay such
additional amounts would not have arisen but for a failure by such Non-U.S.
Lender to comply with the provisions of Section 2.17(d), (ii) any of the
representations or certifications made by a Non-U.S. Lender pursuant to Section
2.17(d) are incorrect at the time a payment hereunder is made, other than by
reason of any change in treaty, law or regulation having effect after the date
such representations or certifications were made, or (iii) the obligations to
withhold amounts with respect to United States federal withholding tax existed
on the date such Non-U.S. Lender became a party to this Agreement; provided,
                                                                   --------
however, that this clause (iii) shall not apply to the extent that (y) the
-------
indemnity payments or additional amounts any Lender would be entitled to receive
(without regard to this

                                       44
<PAGE>

clause (iii)) do not exceed the indemnity payment or additional amounts that the
person making the assignment, participation or transfer to such Lender would
have been entitled to receive in the absence of such assignment, participation
or transfer, or (z) such assignment, participation or transfer was requested by
the Borrower.

     (f) Nothing in this Section 2.17 shall be deemed to require any Lender to
disclose any confidential information concerning its tax affairs.

     2.18 Compensation. The Borrower will compensate each Lender upon written
          ------------
demand (which demand shall set forth the basis for requesting such compensation
and shall be copied to the Agent) for all losses, expenses and liabilities
(including, without limitation, any loss, expense or liability incurred by
reason of the liquidation or reemployment of deposits or other funds required by
such Lender to fund or maintain LIBOR Loans) that such Lender may incur or
sustain (i) if for any reason (other than a default by such Lender or the Agent
or, with respect to any Borrowing, a change in law described in Section 2.16 or
any Taxes payable as described in Section 2.17, in each such case arising during
the three (3) Business Days after a Notice of Borrowing and of which the
Borrower did not have knowledge at the time the Borrower submitted such Notice
of Borrowing, provided further that the Lenders shall not be required to extend
such Borrowing as a LIBOR Loan if such extension would create undue hardship for
such Lender) a Borrowing or continuation of, or conversion into, a LIBOR Loan
does not occur on a date specified therefor in a Notice of Borrowing or Notice
of Conversion/ Continuation, (ii) if any repayment, prepayment or conversion of
any LIBOR Loan occurs (other than a conversion of a LIBOR Loan pursuant to
Sections 2.16(c) and 2.16(d) on a date other than the last day of an Interest
Period applicable thereto (including as a consequence of acceleration of the
maturity of the Loans pursuant to Section 9.2), (iii) if any prepayment of any
LIBOR Loan is not made on any date specified in a notice of prepayment given by
the Borrower or (iv) as a consequence of any other failure by the Borrower to
make any payments with respect to any LIBOR Loan when due hereunder. Calculation
of all amounts payable to a Lender under this Section 2.18 shall be made as
though such Lender had actually funded its relevant LIBOR Loan through the
purchase of a Eurodollar deposit bearing interest at the LIBOR Rate in an amount
equal to the amount of such LIBOR Loan, having a maturity comparable to the
relevant Interest Period; provided, however, that each Lender may fund its LIBOR
                          --------  -------
Loans in any manner it sees fit and the foregoing assumption shall be utilized
only for the calculation of amounts payable under this Section 2.18.
Determinations made in good faith by any Lender for purposes of this Section
2.18 of any such losses, expenses or liabilities shall, absent manifest error,
be conclusive.

     2.19 Substitution of Lender. In the event that any Lender shall have
          ----------------------
delivered a notice or certificate pursuant to Section 2.16 or the Borrower shall
be required to pay additional amounts to any Lender under Section 2.17, the
Borrower shall have the right, at its own expense, upon notice to such Lender
and the Agent, to require such Lender to transfer and assign without recourse
(in accordance with and subject to the provisions set forth in Section 11.7) all
its interests, rights and obligations under this Agreement to another Eligible
Assignee which shall assume such obligations, provided, that, (i) no such
assignment shall conflict with any law, rule, regulation or order of any
Governmental Authority and (ii) the Borrower shall pay or cause to be paid to
the affected Lender in immediately available funds on the date of such
assignment the entire amount of principal of and interest accrued to the date of
payment on the Loans made by it hereunder and all other amounts accrued for its
account or owed to it hereunder; provided,

                                       45
<PAGE>

further, that, if prior to any such assignment the circumstances or event that
resulted in such Lender's notice or certificate under Section 2.16 or demand for
additional amounts under Section 2.17, as the case may be, shall cease to exist
or become inapplicable for any reason or if such Lender shall waive its rights
in respect of such circumstances or event under Section 2.16 or 2.17, as the
case may be, then such Lender shall not thereafter be required to make any such
assignment hereunder.

                                   ARTICLE III

                                LETTERS OF CREDIT

     3.1 Issuance. Subject to and upon the terms and conditions herein set
         --------
forth, so long as no Default or Event of Default has occurred and is continuing,
the Issuing Lender will, at any time and from time to time on and after the
Closing Date and prior to the earlier of (i) the seventh day prior to the
Maturity Date and (ii) the Termination Date, and upon request by the Borrower in
accordance with the provisions of Section 3.2, issue for the account of the
Borrower one or more irrevocable standby letters of credit denominated in
Dollars and in a form customarily used or otherwise approved by the Issuing
Lender (together with all amendments, modifications and supplements thereto,
substitutions therefor and renewals and restatements thereof, collectively, the
"Letters of Credit"). The Stated Amount of each Letter of Credit shall not be
less than $100,000 and there shall not be more than seven (7) Letters of Credit
outstanding at one time. Notwithstanding the foregoing:

     (a) No Letter of Credit shall be issued the Stated Amount upon issuance of
which (i) when added to the aggregate Letter of Credit Exposure of the Lenders
at such time, would exceed $5,000,000 or (ii) when added to the sum of (x) the
aggregate Letter of Credit Exposure of all Lenders at such time, (y) the
aggregate principal amount of all Revolving Loans then outstanding and (z) the
aggregate principal amount of all Swingline Loans then outstanding, would exceed
the aggregate Revolving Credit Commitments at such time;

     (b) No Letter of Credit shall be issued that by its terms expires later
than the seventh day prior to the Maturity Date or, in any event, more than one
(1) year after its date of issuance; provided, however, that a Letter of Credit
                                     --------  -------
may, if requested by the Borrower, provide by its terms, and on terms acceptable
to the Issuing Lender, for renewal for successive periods of one year or less
(but not beyond the seventh day prior to the Maturity Date), unless and until
the Issuing Lender shall have delivered a notice of nonrenewal to the
beneficiary of such Letter of Credit; and

     (c) The Issuing Lender shall be under no obligation to issue any Letter of
Credit if, at the time of such proposed issuance, (i) any order, judgment or
decree of any Governmental Authority or arbitrator shall purport by its terms to
enjoin or restrain the Issuing Lender from issuing such Letter of Credit, or any
Requirement of Law applicable to the Issuing Lender or any request or directive
(whether or not having the force of law) from any Governmental Authority with
jurisdiction over the Issuing Lender shall prohibit, or request that the Issuing
Lender refrain from, the issuance of letters of credit generally or such Letter
of Credit in particular or shall

                                       46
<PAGE>

impose upon the Issuing Lender with respect to such Letter of Credit any
restriction or reserve or capital requirement (for which the Issuing Lender is
not otherwise compensated) not in effect on the Closing Date, or any
unreimbursed loss, cost or expense that was not applicable, or in effect as of
the Closing Date and that the Issuing Lender in good faith deems material to it,
or (ii) the Issuing Lender shall have actual knowledge, or shall have received
notice from any Lender, prior to the issuance of such Letter of Credit that one
or more of the conditions specified in Sections 4.1 (if applicable) or 4.2 are
not then satisfied (or have not been waived in writing as required herein) or
that the issuance of such Letter of Credit would violate the provisions of
subsection (a) above.

     3.2 Notices. Whenever the Borrower desires the issuance of a Letter of
         -------
Credit, the Borrower will give the Issuing Lender written notice with a copy to
the Agent not later than 11:00 a.m., Charlotte time, three (3) Business Days (or
such shorter period as is acceptable to the Issuing Lender in any given case)
prior to the requested date of issuance thereof. Each such notice (each, a
"Letter of Credit Notice") shall be irrevocable, shall be given in the form of
Exhibit B-4 and shall specify (i) the requested date of issuance, which shall be
a Business Day, (ii) the requested Stated Amount and expiry date of the Letter
of Credit, and (iii) the name and address of the requested beneficiary or
beneficiaries of the Letter of Credit. The Borrower will also complete any
application procedures and documents required by the Issuing Lender in
connection with the issuance of any Letter of Credit, provided, however, that
the terms of this Agreement shall govern in the event that there is any
inconsistency between the terms of such application and any of the terms and
conditions hereof. Upon its issuance of any Letter of Credit, the Issuing Lender
will promptly notify the Agent of such issuance, and the Agent will give prompt
notice thereof to each Lender.

     3.3 Participations. Immediately upon the issuance of any Letter of Credit,
         --------------
the Issuing Lender shall be deemed to have sold and transferred to each Lender,
and each Lender shall be deemed irrevocably and unconditionally to have
purchased and received from the Issuing Lender, without recourse or warranty, an
undivided interest and participation, pro rata (based on the percentage of the
aggregate Revolving Credit Commitments represented by such Lender's Revolving
Credit Commitment), in such Letter of Credit, each drawing made thereunder and
the obligations of the Borrower under this Agreement with respect thereto and
any security therefor or guaranty pertaining thereto; provided, however, that
                                                      --------  -------
the fee relating to Letters of Credit described in Section 2.9(c) shall be
payable directly to the Issuing Lender as provided therein, and the Lenders
shall have no right to receive any portion thereof. Upon any change in the
Revolving Credit Commitments of any of the Lenders pursuant to Section 11.7(a),
with respect to all outstanding Letters of Credit and Reimbursement Obligations
there shall be an automatic adjustment to the participations pursuant to this
Section to reflect the new pro rata shares of the assigning Lender and the
Assignee.

     3.4 Reimbursement. The Borrower hereby agrees to reimburse the Issuing
         -------------
Lender by making payment to the Agent, for the account of the Issuing Lender, in
immediately available funds, for any payment made by the Issuing Lender under
any Letter of Credit (each such amount so paid until reimbursed, together with
interest thereon payable as provided hereinbelow, a "Reimbursement Obligation")
                                                     ------------------------
immediately after, and in any event within one (1) Business Day after its
receipt of notice of, such payment (provided that any such Reimbursement
                                    --------
Obligation shall be deemed timely satisfied (but nevertheless subject to the
payment of interest thereon as

                                       47
<PAGE>

provided hereinbelow) if satisfied pursuant to a Borrowing of Revolving Loans
made on or prior to the next Business Day following the date of the Borrower's
receipt of notice of such payment), together with interest on the amount so paid
by the Issuing Lender, to the extent not reimbursed prior to 1:00 p.m.,
Charlotte time, on the date of such payment or disbursement, for the period from
the date of the respective payment to the date the Reimbursement Obligation
created thereby is satisfied, at the Adjusted Base Rate applicable to Revolving
Loans as in effect from time to time during such period, such interest also to
be payable on demand. The Issuing Lender will provide the Agent and the Borrower
with prompt notice of any payment or disbursement made under any Letter of
Credit, although the failure to give, or any delay in giving, any such notice
shall not release, diminish or otherwise affect the Borrower's obligations under
this Section or any other provision of this Agreement. The Agent will promptly
pay to the Issuing Lender any such amounts received by it under this Section.

     3.5 Payment by Revolving Loans. In the event that the Issuing Lender makes
         --------------------------
any payment under any Letter of Credit and the Borrower shall not have timely
satisfied in full its Reimbursement Obligation to the Issuing Lender pursuant to
Section 3.4, and to the extent that any amounts then held in the Cash Collateral
Account established pursuant to Section 3.8 shall be insufficient to satisfy
such Reimbursement Obligation in full, the Issuing Lender will promptly notify
the Agent, and the Agent will promptly notify each Lender, of such failure. If
the Agent gives such notice prior to 11:00 a.m., Charlotte time, on any Business
Day, each Lender will make available to the Agent, for the account of the
Issuing Lender, its pro rata share (based on the percentage of the aggregate
Revolving Credit Commitments represented by such Lender's Revolving Credit
Commitment) of the amount of such payment on such Business Day in immediately
available funds. If the Agent gives such notice after 11:00 a.m., Charlotte
time, on any Business Day, each such Lender shall make its pro rata share of
such amount available to the Agent on the next succeeding Business Day. If and
to the extent any Lender shall not have so made its pro rata share of the amount
of such payment available to the Agent, such Lender agrees to pay to the Agent,
for the account of the Issuing Lender, forthwith on demand such amount, together
with interest thereon at the Federal Funds Rate for each day from such date
until the date such amount is paid to the Agent. The failure of any Lender to
make available to the Agent its pro rata share of any payment under any Letter
of Credit shall not relieve any other Lender of its obligation hereunder to make
available to the Agent its pro rata share of any payment under any Letter of
Credit on the date required, as specified above, but no Lender shall be
responsible for the failure of any other Lender to make available to the Agent
such other Lender's pro rata share of any such payment. Each such payment by a
Lender under this Section of its pro rata share of an amount paid by the Issuing
Lender shall constitute a Revolving Loan by such Lender (the Borrower being
deemed to have given a timely Notice of Borrowing therefor) and shall be treated
as such for all purposes of this Agreement; provided that for purposes of
                                            --------
determining the aggregate Unutilized Revolving Credit Commitments immediately
prior to giving effect to the application of the proceeds of such Revolving
Loans, the Reimbursement Obligation being satisfied thereby shall be deemed not
to be outstanding at such time.

     3.6 Payment to Lenders. Whenever the Issuing Lender receives a payment in
         ------------------
respect of a Reimbursement Obligation as to which the Agent has received, for
the account of the Issuing Lender, any payments from the Lenders pursuant to
Section 3.5, the Issuing Lender will promptly pay to the Agent, and the Agent
will promptly pay to each Lender that has paid its pro

                                       48
<PAGE>

rata share thereof, in immediately available funds, an amount equal to such
Lender's ratable share (based on the proportionate amount funded by such Lender
to the aggregate amount funded by all Lenders) of such Reimbursement Obligation.

     3.7 Obligations Absolute. The Reimbursement Obligations of the Borrower,
         --------------------
and the obligations of the Lenders under Section 3.5 to make payments to the
Agent, for the account of the Issuing Lender, with respect to Letters of Credit,
shall be irrevocable, shall remain in effect until the Issuing Lender shall have
no further obligations to make any payments or disbursements under any
circumstances with respect to any Letter of Credit, and, except to the extent
resulting from any fraud, gross negligence or willful misconduct on the part of
the Issuing Lender, shall be absolute and unconditional, shall not be subject to
counterclaim, setoff or other defense or any other qualification or exception
whatsoever and shall be made in accordance with the terms and conditions of this
Agreement under all circumstances, including, without limitation, any of the
following circumstances; provided, that the making of such reimbursement
payments shall not affect the rights of the Borrower or the Lenders to seek
damages or other remedies arising from any breach of the Issuing Lender's
standard of care as set forth in the final paragraph of this Section 3.7:

     (a) Any lack of validity or enforceability of this Agreement, any of the
other Credit Documents or any documents or instruments relating to any Letter of
Credit;

     (b) Any change in the time, manner or place of payment of, or in any other
term of, all or any of the Obligations in respect of any Letter of Credit or any
other amendment, modification or waiver of or any consent to departure from any
Letter of Credit or any documents or instruments relating thereto, in each case
whether or not the Borrower has notice or knowledge thereof;

     (c) The existence of any claim, setoff, defense or other right that the
Borrower may have at any time against a beneficiary named in a Letter of Credit,
any transferee of any Letter of Credit (or any Person for whom any such
transferee may be acting), the Agent, the Issuing Lender, any Lender or other
Person, whether in connection with this Agreement, any Letter of Credit, the
transactions contemplated hereby or any unrelated transactions (including any
underlying transaction between the Borrower and the beneficiary named in any
such Letter of Credit);

     (d) Any draft, certificate or any other document presented under the Letter
of Credit proving to be forged, fraudulent, invalid or insufficient in any
respect or any statement therein being untrue or inaccurate in any respect
(provided that such draft, certificate or other document appears on its face to
 --------
comply with the terms of such Letter of Credit), any errors, omissions,
interruptions or delays in transmission or delivery of any messages, by mail,
telecopier or otherwise, or any errors in translation or in interpretation of
technical terms;

     (e) Any defense based upon the failure of any drawing under a Letter of
Credit to conform to the terms of the Letter of Credit (provided that any draft,
                                                        --------
certificate or other document presented pursuant to such Letter of Credit
appears on its face to comply with the terms thereof), any nonapplication or
misapplication by the beneficiary or any transferee of the

                                       49
<PAGE>

proceeds of such drawing or any other act or omission of such beneficiary or
transferee in connection with such Letter of Credit;

     (f) The exchange, release, surrender or impairment of any Collateral or
other security for the Obligations;

     (g) The occurrence of any Default or Event of Default; or

     (h) Any other circumstance or event whatsoever, including, without
limitation, any other circumstance that might otherwise constitute a defense
available to, or a discharge of, the Borrower or a guarantor.

Any action taken or omitted to be taken by the Issuing Lender under or in
connection with any Letter of Credit, if taken or omitted in the absence of
fraud, gross negligence or willful misconduct, shall be binding upon the
Borrower and each Lender and shall not create or result in any liability of the
Issuing Lender to the Borrower or any Lender. It is expressly understood and
agreed that, for purposes of determining whether a wrongful payment under a
Letter of Credit resulted from the Issuing Lender's gross negligence or willful
misconduct, (i) the Issuing Lender's acceptance of documents that appear on
their face to comply with the terms of such Letter of Credit, without
responsibility for further investigation, regardless of any notice or
information to the contrary, (ii) the Issuing Lender's exclusive reliance on the
documents presented to it under such Letter of Credit as to any and all matters
set forth therein, including the amount of any draft presented under such Letter
of Credit, whether or not the amount due to the beneficiary thereunder equals
the amount of such draft and whether or not any document presented pursuant to
such Letter of Credit proves to be insufficient in any respect (so long as such
document appears on its face to comply with the terms of such Letter of Credit),
and whether or not any other statement or any other document presented pursuant
to such Letter of Credit proves to be forged or invalid or any statement therein
proves to be inaccurate or untrue in any respect whatsoever, and (iii) any
noncompliance in any immaterial respect of the documents presented under such
Letter of Credit with the terms thereof shall, in each case, be deemed not to
constitute gross negligence or willful misconduct of the Issuing Lender.

     3.8 Cash Collateral Account. At any time and from time to time (i) after
         -----------------------
the occurrence and during the continuance of an Event of Default, the Agent, at
the direction or with the consent of the Required Lenders, may require the
Borrower to deliver to the Agent such additional amount of cash as is equal to
the aggregate Stated Amount of all Letters of Credit at any time outstanding
(whether or not any beneficiary under any Letter of Credit shall have drawn or
be entitled at such time to draw thereunder) and (ii) in the event of a
prepayment under Section 2.6(b), the Agent will retain such amount as may then
be required to be retained, such amount to be held by the Agent in a cash
collateral account (the "Cash Collateral Account"). The Borrower hereby grants
to the Agent, for the benefit of the Issuing Lender and the Lenders, a Lien upon
and security interest in the Cash Collateral Account and all amounts held
therein from time to time as security for Letter of Credit Exposure, and for
application to the Borrower's Reimbursement Obligations as and when the same
shall arise. The Agent shall have exclusive dominion and control, including the
exclusive right of withdrawal, over such account. Other than any interest on the
investment of such amounts in Cash Equivalents, which investments shall be made
at the direction of the Borrower (unless a Default or Event of Default shall
have

                                       50
<PAGE>

occurred and be continuing, in which case the determination as to investments
shall be made at the option and in the discretion of the Agent), amounts in the
Cash Collateral Account shall not bear interest. Interest and profits, if any,
on such investments shall accumulate in such account. In the event of a drawing,
and subsequent payment by the Issuing Lender, under any Letter of Credit at any
time during which any amounts are held in the Cash Collateral Account, the Agent
will deliver to the Issuing Lender an amount equal to the Reimbursement
Obligation created as a result of such payment (or, if the amounts so held are
less than such Reimbursement Obligation, all of such amounts) to reimburse the
Issuing Lender therefor. Any amounts remaining in the Cash Collateral Account
after the expiration of all Letters of Credit and reimbursement in full of the
Issuing Lender for all of its obligations thereunder shall be held by the Agent,
for the benefit of the Borrower, to be applied against the Obligations in such
order and manner as the Agent may direct. If the Borrower is required to provide
cash collateral pursuant to Section 2.6(b), such amount (to the extent not
applied as aforesaid) shall be returned to the Borrower on demand, provided that
                                                                   --------
after giving effect to such return (i) the sum of (x) the aggregate principal
amount of all Revolving Loans outstanding at such time, (y) the aggregate
principal amount of all Swingline Loans outstanding at such time and (z) the

all liability for taxes of the Borrower and its Subsidiaries for the periods

provision of the Exchange Act.

financial statements, to the absence of notes required by GAAP and to normal
year-end adjustments) and present fairly the financial condition of the Borrower
and its Subsidiaries on a consolidated basis as of the respective dates thereof
and the consolidated results of operations of the Borrower and its Subsidiaries
for the respective periods then ended. Except as reflected in the most recent
financial statements referred to above and the notes thereto, there are no
material liabilities or obligations with respect to the Borrower or any of its
Subsidiaries of the type required to be disclosed by GAAP. Consolidated EBITDA
for the 11-month period ended November 30, 2001 is not less than $151,250,000.

     (b) The unaudited pro forma balance sheet of the Borrower as of November
30, 2001, a copy of which has heretofore been delivered to the Agent, gives pro
forma effect to the issuance of the Subordinated Notes, the initial extensions
of credit made under this Agreement, and the payment of transaction fees and
expenses related to the foregoing, all as if such events had occurred on such
date (the "Pro Forma Balance Sheet"). The Pro Forma Balance Sheet has been
prepared in accordance with GAAP (subject to the absence of footnotes required
by GAAP and subject to normal year-end adjustments) and, subject to stated
assumptions made in good faith and having a reasonable basis set forth therein,
presents fairly the financial condition of the Borrower on an unaudited pro
forma basis as of the date set forth therein after giving effect to the
consummation of the transactions described above.

     (c) The Borrower has prepared, and has heretofore furnished to the Agent a
copy of, the projected balance sheets and statements of income and cash flows of
the Borrower on an annual basis from the fiscal year ending December 31, 2001
through the fiscal year ending December 31, 2007, in each case giving effect to
the issuance of the Subordinated Notes, the initial extensions of credit made
under this Agreement, the payment of transaction fees and expenses related to
the foregoing, and the Restructuring (the "Projections"). In the opinion of
management of the Borrower, the assumptions used in the preparation of the
Projections were fair, complete and reasonable when made and continue to be
fair, complete and reasonable as of the date hereof. The Projections have been
prepared in good faith by the senior management of the Borrower, and represent a
reasonable estimate of the future performance and financial condition of the
Borrower, based on assumptions (including as to business conditions) believed to
be reasonable at the time and subject to the uncertainties and approximations
inherent in any projections.

     (d) Each of the Borrower and its Subsidiaries, after giving effect to the
consummation of the transactions contemplated hereby, (i) has capital sufficient
to carry on its businesses as conducted and as proposed to be conducted, (ii)
has assets with a fair saleable value, determined on a going concern basis, (y)
not less than the amount required to pay the probable liability on its existing
debts as they become absolute and matured and (z) greater than the total amount
of its liabilities (including identified contingent liabilities, valued at the
amount that can reasonably be

                                       60
<PAGE>

expected to become absolute and matured), and (iii) does not intend to, and does
not reasonably believe that it will, incur debts or liabilities beyond its
ability to pay such debts and liabilities as they mature.

     5.12 Ownership of Properties.
          -----------------------

     (a) Each of the Borrower and its Subsidiaries (i) has good and marketable
title to all real property owned by it, (ii) holds interests as lessee under
valid leases in full force and effect with respect to all material leased real
and personal property used in connection with its business, (iii) possesses or

trade names and other assets sufficient to enable it to continue to conduct its
business substantially as heretofore conducted and without any material conflict
with the rights of others, and (iv) has good title to all of its other
properties and assets reflected in the most recent financial statements referred
to in Section 5.11(a) (except as sold or otherwise disposed of since the date
thereof in the ordinary course of business), in each case under (i), (ii), (iii)
and (iv) above free and clear of all Liens other than Permitted Liens.

     (b) Schedule 5.12 lists, as of the Closing Date, all owned real property
interests of the Borrower and its Subsidiaries, indicating in each case the
identity of the owner, the address of the property, the nature of use of the
premises and whether such interest is or shall be subject to a Mortgage.

     5.13 ERISA.
          -----

     (a) Each of the Borrower and its ERISA Affiliates is in compliance in all
material respects with the applicable provisions of ERISA, and each Plan is and
has been administered in compliance in all material respects with all applicable
Requirements of Law, including, without limitation, the applicable provisions of
ERISA and the Internal Revenue Code. No ERISA Event (i) has occurred within the
five-year period ending immediately prior to the Closing Date, (ii) has occurred
and is continuing, or (iii) to the knowledge of the Borrower, is reasonably
expected to occur with respect to any Plan. No Plan has any Unfunded Pension
Liability as of the most recent annual valuation date applicable thereto, and
neither the Borrower nor any ERISA Affiliate has engaged in a transaction that
could be subject to Section 4069 or 4212(c) of ERISA.

     (b) Neither the Borrower nor any ERISA Affiliate has had a complete or
partial withdrawal from any Multiemployer Plan, and to the knowledge of the
Borrower neither the Borrower nor any ERISA Affiliate would become subject to
any liability under ERISA that would have a Material Adverse Effect if the
Borrower or any ERISA Affiliate were to withdraw completely from all
Multiemployer Plans as of the most recent valuation date. To the knowledge of
the Borrower, no Multiemployer Plan is in "reorganization" or is "insolvent"
within the meaning of such terms under ERISA.

     5.14 Environmental Matters.
          ---------------------

     (a) No Hazardous Substances are or have been generated, used, located,

portion of any real property, leased or owned, of the Borrower or any of its

                                       61
<PAGE>

any of its Subsidiaries has been used by the Borrower or any of its Subsidiaries
or, to the knowledge of the Borrower, by any other Person, as or for a mine, a
landfill, a dump or other disposal facility, a gasoline service station, or
(other than for petroleum substances stored in the ordinary course of business)
a petroleum products storage facility; no portion of such real property or any
other real property at any time leased, owned or operated by the Borrower or any
of its Subsidiaries has, pursuant to any Environmental Law, been placed on the
"National Priorities List" or "CERCLIS List" (or any similar federal, state or
local list) of sites subject to possible environmental problems; and there are
not and have never been any underground storage tanks situated on any real
property, leased or owned, of the Borrower or any of its Subsidiaries.

     (c) All activities and operations of the Borrower and its Subsidiaries are
in compliance with the requirements of all applicable Environmental Laws, except
to the extent the failure so to comply, individually or in the aggregate, would
not be reasonably likely to have a Material Adverse Effect. Each of the Borrower
and its Subsidiaries has obtained all licenses and permits under Environmental
Laws necessary to its respective operations; all such licenses and permits are
being maintained in good standing; and each of the Borrower and its Subsidiaries
is in compliance with all terms and conditions of such licenses and permits,
except for such licenses and permits the failure to obtain, maintain or comply
with which would not, individually or in the aggregate, have a Material Adverse
Effect. Neither the Borrower nor any of its Subsidiaries is involved in any
suit, action or proceeding, or has received any notice, complaint or other
request for information from any Governmental Authority or other Person, with
respect to any actual or alleged Environmental Claims that, would, individually
or in the aggregate, have a Material Adverse Effect; and, to the knowledge of
the Borrower, there are no threatened actions, suits, proceedings or
investigations with respect to any such Environmental Claims, nor any basis
therefor.

     5.15 Compliance with Laws. Each of the Borrower and its Subsidiaries has
          --------------------
timely filed all material reports, documents and other materials required to be
filed by it under all applicable Requirements of Law with any Governmental
Authority, has retained all material records and documents required to be
retained by it under all applicable Requirements of Law, and is otherwise in
compliance with all applicable Requirements of Law in respect of the conduct of
its business and the ownership and operation of its properties, except for such
Requirements of Law the failure to comply with which, individually or in the
aggregate, would not have a Material Adverse Effect.

          ---------
insurance policies or arrangements carried or maintained by the Borrower and its
Subsidiaries as of the Closing Date, indicating in each case the insurer, policy

     5.19 Security Documents. The provisions of each of the Security Documents
          ------------------

are and will be effective to create in favor of the Agent, for its benefit and
the benefit of the Lenders, a valid and enforceable security interest in and
Lien upon all right, title and interest of each of the Borrower and its
Subsidiaries that is a party thereto in and to the Collateral purported to be

          -------------------------------------
Borrower and its Subsidiaries have been and will continue to be adjusted to
reflect reimbursement policies under all applicable Requirements of Law and
other Third Party Payor Arrangements to which the Borrower or such Subsidiary
(or the physician practices for which the Borrower or such Subsidiary bills and
collects) is subject, and do not exceed in any material respect amounts the
Borrower or such Subsidiary (or the physician practices for which the Borrower
or such Subsidiary bills and collects) is entitled to receive under any
capitation arrangement, fee schedule, discount formula, cost-based reimbursement
or other adjustment or limitation to usual charges. All physician practices
billings by the Borrower and each Subsidiary pursuant to physician practices'
Third Party Payor Arrangements have been made in compliance with all applicable
Requirements of Law, except where failure to comply would not, individually

                                       63
<PAGE>

or in the aggregate, be reasonably likely to have a Material Adverse Effect; and
there has been no intentional or material overbilling or overcollection pursuant
to any Third Party Payor Arrangements, other than as created by routine
adjustments and disallowances made in the ordinary course of business by the
payors with respect to such billings.

     Commitments to meet its ongoing working capital requirements.

approved in writing by the Required Lenders) all conditions thereto set forth in
this Section and in the description furnished under clause (i) of subsection (b)
above have been satisfied, that the same is permitted in accordance with the
terms of this Agreement, and that the matters certified to by the Financial
Officer of the Borrower in the certificate referred to in clause (iv) of

new Subsidiary initially does not meet the criteria of clauses (a) or (b) of

Subsidiary), in form and substance reasonably satisfactory to the Agent, as the
Agent may reasonably request in connection therewith and will

                                       71

take such other action as the Agent may reasonably request to create in favor of

mortgages and other Liens in and upon such assets and properties of the Borrower
or such Subsidiary as are not covered by the Security Documents executed and
delivered on the Closing Date or pursuant to Section 6.9 and as may be
reasonably requested from time to time by the Required Lenders (including,
without limitation, Liens on assets acquired by the Borrower or a Subsidiary in
connection with any Permitted Acquisition); provided that the Borrower and its
                                            --------
Subsidiaries shall promptly grant to the Agent (without the need for any request
by the Required Lenders of the Agent) security interests, mortgages and other
applicable Liens in and upon all real and personal property at any time acquired
out of the ELLF (without the need for any request by the Required Lenders or the
Agent) except to the extent such assets are used to secure purchase money
financing permitted pursuant to Section 8.3(vi) or another credit facility that
would be defined as the ELLF. Such security interests, mortgages and Liens shall
be granted pursuant to documentation in form and substance reasonably
satisfactory to the Agent and shall constitute valid and perfected security
interests and Liens, subject to no Liens other than Permitted Liens. Without
limitation of the foregoing, (i) in connection with the grant of any mortgage or
deed of trust with respect to any interest in real property, the Borrower will,
and will cause each applicable Subsidiary to, at the Borrower's expense,
prepare, obtain and deliver to the Agent any environmental assessments,

may reasonably request or as may be required under applicable banking laws and
regulations.

pursuant to the Security Documents and to effect, confirm or further assure or
protect and preserve the interests, rights and remedies of the Agent and the
Lenders under this Agreement and the other Credit Documents.

Subsidiaries or any of their respective properties and the same shall not be

or in any event later than five days prior to the date of any proposed sale
thereunder;

     (i) Any Security Document to which the Borrower or any of its Subsidiaries
is now or hereafter a party shall for any reason cease to be in full force and
effect or cease to be effective to give the Agent a valid and perfected security
interest in and Lien upon any material part of the Collateral purported to be
covered thereby, subject to no Liens other than Permitted Liens, in each case
unless any such cessation occurs in accordance with the terms thereof or is due
to any act or failure to act on the part of the Agent or any Lender; or the

Governmental Authority in response to any alleged failure by the Borrower or any

(including, without limitation, applicable laws and regulations relating to
healthcare providers), and such Limitation or other action, individually or in
the aggregate, would be reasonably likely to have a Material Adverse Effect;

     (l) Any one or more Environmental Claims shall have been asserted against
the Borrower or any of its Subsidiaries (or a reasonable basis shall exist
therefor); the Borrower and its Subsidiaries have incurred or would be
reasonably likely to incur liability as a result thereof; and such liability,
individually or in the aggregate, has or would be reasonably likely to have a
Material Adverse Effect;

     (m) Any agreement or contract to which the Borrower or any of its

consist of a majority of the individuals who constituted the Board of Directors
as of the date hereof or who shall have become a member thereof subsequent to
the date hereof after having been nominated, or otherwise approved in writing,
by at least a majority of individuals who constituted the Board of Directors of
the Borrower as of the date hereof (or their replacements approved as herein
required).

     9.2 Remedies: Termination of Commitments, Acceleration, etc. Upon and at
         -------------------------------------------------------
any time after the occurrence and during the continuance of any Event of
Default, the Agent shall at the direction, or may with the consent, of the
Required Lenders, take any or all of the following actions at the same or
different times:

                                       85
<PAGE>

     (a) Declare the Revolving Credit Commitments, the Swingline Commitment, and
the Issuing Lender's obligation to issue Letters of Credit, to be terminated,
whereupon the same shall terminate (provided that, upon the occurrence of an
                                    --------
Event of Default pursuant to Section 9.1(f) or Section 9.1(g), the Revolving
Credit Commitments, the Swingline Commitment and the Issuing Lender's obligation
to issue Letters of Credit shall automatically be terminated);

     (b) Declare all or any part of the outstanding principal amount of the
Loans to be immediately due and payable, whereupon the principal amount so
declared to be immediately due and payable, together with all interest accrued
thereon and all other amounts accrued and unpaid under this Agreement, the Notes
and the other Credit Documents (but excluding any amounts owing under any Hedge
Agreement), shall become immediately due and payable without presentment,
demand, protest, notice of intent to accelerate or other notice or legal process
of any kind, all of which are hereby knowingly and expressly waived by the
Borrower (provided that, upon the occurrence of an Event of Default pursuant to
Section 9.1(f) or Section 9.1(g), all of the outstanding principal amount of the
Loans and all other amounts described in this subsection (b) shall automatically
become immediately due and payable without presentment, demand, protest, notice
of intent to accelerate or other notice or legal process of any kind, all of
which are hereby knowingly and expressly waived by the Borrower);

     (c) Direct the Borrower to deposit (and the Borrower hereby agrees,
forthwith upon receipt of notice of such direction from the Agent, to deposit)
with the Agent from time to time such additional amount of cash as is equal to
the aggregate Stated Amount of all Letters of Credit then outstanding (whether
or not any beneficiary under any Letter of Credit shall have drawn or be
entitled at such time to draw thereunder), such amount to be held by the Agent
in the Cash Collateral Account as security for the Letter of Credit Exposure as
described in Section 3.8; and

     (d) Exercise all rights and remedies available to it under this Agreement,
the other Credit Documents and applicable law.

     9.3 Remedies: Set-Off. In addition to all other rights and remedies
         -----------------
available under the Credit Documents or applicable law or otherwise, upon and at
any time after the occurrence and during the continuance of any Event of
Default, each Lender may, and each is hereby authorized by the Borrower, at any
such time and from time to time, to the fullest extent permitted by applicable
law, without presentment, demand, protest or other notice of any kind, all of
which are hereby knowingly and expressly waived by the Borrower, to set off and
to apply any and all deposits (general or special, time or demand, provisional
or final) and any other property at any time held (including at any branches or
agencies, wherever located), and any other indebtedness at any time owing, by
such Lender to or for the credit or the account of the Borrower against any or
all of the Obligations to such Lender now or hereafter existing, whether or not
such Obligations may be contingent or unmatured, the Borrower hereby granting to
each Lender a continuing security interest in and Lien upon all such deposits
and other property as security for such Obligations. Each Lender agrees promptly
to notify the Borrower and the Agent after any such set-off and application;
provided, however, that the failure to give such notice shall not affect the
--------  -------
validity of such set-off and application.

                                    THE AGENT

     10.1 Appointment. Each Lender hereby irrevocably appoints and authorizes
          -----------
First Union to act as Agent hereunder and under the other Credit Documents and
to take such actions as agent on its behalf hereunder and under the other Credit
Documents, and to exercise such powers and to perform such duties, as are
specifically delegated to the Agent by the terms hereof or thereof, together
with such other powers and duties as are reasonably incidental thereto.

     10.2 Nature of Duties. The Agent shall have no duties or responsibilities
          ----------------
other than those expressly set forth in this Agreement and the other Credit
Documents. The Agent shall not have, by reason of this Agreement or any other
Credit Document, a fiduciary relationship in respect of any Lender; and nothing
in this Agreement or any other Credit Document, express or implied, is intended
to or shall be so construed as to impose upon the Agent any obligations or
liabilities in respect of this Agreement or any other Credit Document except as
expressly set forth herein or therein. The Agent may execute any of its duties
under this Agreement or any other Credit Document by or through agents or
attorneys-in-fact and shall not be responsible for the negligence or misconduct
of any agents or attorneys-in-fact that it selects with reasonable care. The
Agent shall be entitled to consult with legal counsel, independent public
accountants and other experts selected by it with respect to all matters
pertaining to this Agreement and the other Credit Documents and its duties
hereunder and thereunder and shall not be liable for any action taken or omitted
to be taken in good faith by it in accordance with the advice of such counsel,
accountants or experts. The Lenders hereby acknowledge that the Agent shall not
be under any duty to take any discretionary action permitted to be taken by it
pursuant to the provisions of this Agreement or any other Credit Document unless
it shall be requested in writing to do so by the Required Lenders (or, where a
higher percentage of the Lenders is expressly required hereunder, such Lenders).

     10.3 Exculpatory Provisions. Neither the Agent nor any of its officers,
          ----------------------
directors, employees, agents, attorneys-in-fact or Affiliates shall be (i)
liable for any action taken or omitted to be taken by it or such Person under or
in connection with the Credit Documents, except for its or such Person's own
gross negligence or willful misconduct, (ii) responsible in any manner to any
Lender for any recitals, statements, information, representations or warranties
herein or in any other Credit Document or in any document, instrument,
certificate, report or other writing delivered in connection herewith or
therewith, for the execution, effectiveness, genuineness, validity,
enforceability or sufficiency of this Agreement or any other Credit Document, or
for the financial condition of the Borrower, its Subsidiaries or any other
Person, or (iii) required to ascertain or make any inquiry concerning the
performance or observance of any of the terms, provisions or conditions of this
Agreement or any other Credit Document or the existence or possible existence of
any Default or Event of Default, or to inspect the properties, books or records
of the Borrower or any of its Subsidiaries.

     10.4 Reliance by Agent. The Agent shall be entitled to rely, and shall be
          -----------------
fully protected in relying, upon any notice, statement, consent or other
communication (including, without limitation, any thereof by telephone,
telecopy, telex, telegram or cable) believed by it in good faith to be genuine
and correct and to have been signed, sent or made by the proper Person

                                       87
<PAGE>

or Persons. The Agent may deem and treat each Lender as the owner of its
interest hereunder for all purposes hereof unless and until a written notice of
the assignment, negotiation or transfer thereof shall have been given to the
Agent in accordance with the provisions of this Agreement. The Agent shall be
entitled to refrain from taking or omitting to take any action in connection
with this Agreement or any other Credit Document (i) if such action or omission
would, in the reasonable opinion of the Agent, violate any applicable law or any
provision of this Agreement or any other Credit Document or (ii) unless and
until it shall have received such advice or concurrence of the Required Lenders
(or, where a higher percentage of the Lenders is expressly required hereunder,
such Lenders) as it deems appropriate or it shall first have been indemnified to
its satisfaction by the Lenders against any and all liability and expense (other
than liability and expense arising from its own gross negligence or willful
misconduct) that may be incurred by it by reason of taking, continuing to take
or omitting to take any such action. Without limiting the foregoing, no Lender
shall have any right of action whatsoever against the Agent as a result of the
Agent's acting or refraining from acting hereunder or under any other Credit
Document in accordance with the instructions of the Required Lenders (or, where
a higher percentage of the Lenders is expressly required hereunder, such
Lenders), and such instructions and any action taken or failure to act pursuant
thereto shall be binding upon all of the Lenders (including all subsequent
Lenders).

     10.5 Non-Reliance on Agent and Other Lenders. Each Lender expressly
          ---------------------------------------
acknowledges that neither the Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or Affiliates has made any representation
or warranty to it and that no act by the Agent or any such Person hereafter
taken, including any review of the affairs of the Borrower and its Subsidiaries,
shall be deemed to constitute any representation or warranty by the Agent to any
Lender. Each Lender represents to the Agent that (i) it has, independently and
without reliance upon the Agent or any other Lender and based on such documents
and information as it has deemed appropriate, made its own appraisal of and
investigation into the business, prospects, operations, properties, financial
and other condition and creditworthiness of the Borrower and its Subsidiaries
and made its own decision to enter into this Agreement and extend credit to the
Borrower hereunder, and (ii) it will, independently and without reliance upon
the Agent or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action hereunder and under the
other Credit Documents and to make such investigation as it deems necessary to
inform itself as to the business, prospects, operations, properties, financial
and other condition and creditworthiness of the Borrower and its Subsidiaries.
Except as expressly provided in this Agreement and the other Credit Documents,
the Agent shall have no duty or responsibility, either initially or on a
continuing basis, to provide any Lender with any credit or other information
concerning the business, prospects, operations, properties, financial or other
condition or creditworthiness of the Borrower, its Subsidiaries or any other
Person that may at any time come into the possession of the Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

     10.6 Notice of Default. The Agent shall not be deemed to have knowledge or
          -----------------
notice of the occurrence of any Default or Event of Default unless the Agent
shall have received written notice from the Borrower or a Lender referring to
this Agreement, describing such Default or Event of Default and stating that
such notice is a "notice of default." In the event that the Agent receives such
a notice, the Agent will give notice thereof to the Lenders as soon as
reasonably

                                       88
<PAGE>

practicable; provided, however, that if any such notice has also been furnished
             --------  -------
to the Lenders, the Agent shall have no obligation to notify the Lenders with
respect thereto. The Agent shall (subject to Sections 10.4 and 11.6) take such
action with respect to such Default or Event of Default as shall reasonably be
directed by the Required Lenders; provided that, unless and until the Agent
                                  --------
shall have received such directions, the Agent may (but shall not be obligated
to) take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable in the best interests of
the Lenders except to the extent that this Agreement expressly requires that
such action be taken, or not be taken, only with the consent or upon the
authorization of the Required Lenders or all of the Lenders.

     10.7 Indemnification. To the extent the Agent is not reimbursed by or on
          ---------------
behalf of the Borrower, and without limiting the obligation of the Borrower to
do so, the Lenders agree (i) to indemnify the Agent and its officers, directors,
employees, agents, attorneys-in-fact and Affiliates, ratably in proportion to
their respective percentages as used in determining the Required Lenders as of
the date of determination, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses (including, without limitation, attorneys' fees and expenses) or
disbursements of any kind or nature whatsoever that may at any time (including,
without limitation, at any time following the repayment in full of the Loans and
the termination of the Revolving Credit Commitments) be imposed on, incurred by
or asserted against the Agent in any way relating to or arising out of this
Agreement or any other Credit Document or any documents contemplated by or
referred to herein or the transactions contemplated hereby or thereby or any
action taken or omitted by the Agent under or in connection with any of the
foregoing, and (ii) to reimburse the Agent upon demand, ratably in proportion to
their respective percentages as used in determining the Required Lenders as of
the date of determination, for any expenses incurred by the Agent in connection
with the preparation, negotiation, execution, delivery, administration,
amendment, modification, waiver or enforcement (whether through negotiations,
legal proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement or any of the other Credit Documents
(including, without limitation, reasonable attorneys' fees and expenses and
compensation of agents and employees paid for services rendered on behalf of the
Lenders); provided, however, that no Lender shall be liable for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements to the extent resulting from the gross
negligence or willful misconduct of the party to be indemnified.

     10.8 The Agent in its Individual Capacity. With respect to its Revolving
          ------------------------------------
Credit Commitment and Swingline Commitment, the Loans made by it, the Letters of
Credit issued or participated in by it and the Note or Notes issued to it, the
Agent in its individual capacity and not as Agent shall have the same rights and
powers under the Credit Documents as any other Lender and may exercise the same
as though it were not performing the agency duties specified herein; and the
terms "Lenders," "Required Lenders," "holders of Notes" and any similar terms
shall, unless the context clearly otherwise indicates, include the Agent in its
individual capacity. The Agent and its Affiliates may accept deposits from, lend
money to, make investments in, and generally engage in any kind of banking,
trust, financial advisory or other business with the Borrower, any of its
Subsidiaries or any of their respective Affiliates as if the Agent were not
performing the agency duties specified herein, and may accept fees and other
consideration from any of them for services in connection with this Agreement
and otherwise without having to account for the same to the Lenders.

                                       89
<PAGE>

     10.9 Successor Agent. The Agent may resign at any time by giving ten (10)
          ---------------
days' prior written notice to the Borrower and the Lenders. Upon any such notice
of resignation, the Required Lenders will, with the prior written consent of the
Borrower (which consent shall not be unreasonably withheld), appoint from among
the Lenders a successor to the Agent (provided that the Borrower's consent shall
                                      --------
not be required in the event a Default or Event of Default shall have occurred
and be continuing). If no successor to the Agent shall have been so appointed by
the Required Lenders and shall have accepted such appointment within such
ten-day period, then the retiring Agent may, on behalf of the Lenders and after
consulting with the Lenders and the Borrower, appoint a successor Agent from
among the Lenders. Upon the acceptance of any appointment as Agent by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations
hereunder and under the other Credit Documents. After any retiring Agent's
resignation as Agent, the provisions of this Article shall inure to its benefit
as to any actions taken or omitted to be taken by it while it was Agent. If no
successor to the Agent has accepted appointment as Agent by the thirtieth (30th)
day following a retiring Agent's notice of resignation, the retiring Agent's
resignation shall nevertheless thereupon become effective, and the Lenders shall
thereafter perform all of the duties of the Agent hereunder and under the other
Credit Documents until such time, if any, as the Required Lenders appoint a
successor Agent as provided for hereinabove.

     10.10 Collateral Matters.
           ------------------

     (a) The Agent is hereby authorized on behalf of the Lenders, without the
necessity of any notice to or further consent from the Lenders, from time to
time (but without any obligation) to take any action with respect to the
Collateral and the Security Documents that may be necessary to perfect and
maintain perfected the Liens upon the Collateral granted pursuant to the
Security Documents.

     (b) The Lenders hereby authorize the Agent, at its option and in its

the Obligations and all obligations under the ELLF, (ii) constituting property
sold or to be sold or disposed of as part of or in connection with any
disposition expressly permitted hereunder or under any other Credit Document or

                                                                     --------
that the foregoing shall be subject to the terms of the Security Agreement and
the Mortgages and any intercreditor agreement relating thereto. Upon request by
the Agent at any time, the Lenders will confirm in writing the Agent's authority
to release Collateral pursuant to this subsection (b).

     10.11 Issuing Lender and Swingline Lender. The provisions of this Article
           -----------------------------------
(other than Section 10.9 and 10.10) shall apply to the Issuing Lender and the
Swingline Lender mutatis mutandis to the same extent as such provisions apply to
                 ------- --------
the Agent.

     10.12 Syndication Agent, Documentation Agent. Notwithstanding any other
           --------------------------------------
provision of this Agreement or any of the other Credit Documents, the
Syndication Agent and the Documentation Agent are named as such for recognition
purposes only, and in their capacities as

                                       90
<PAGE>

such shall have no powers, rights, duties, responsibilities or liabilities with
respect to this Agreement and the other Credit Documents and the transactions
contemplated hereby and thereby.

the credit arrangement provided under this Agreement, whether in the nature of a
"work-out," in any insolvency or bankruptcy proceeding or otherwise and whether

PRACTICES OF THE INTERNATIONAL CHAMBER OF COMMERCE AS IN EFFECT FROM TIME TO

     11.7 Assignments, Participations.
          ---------------------------

     (a) Each Lender may assign to one or more other Eligible Assignees (each,
an "Assignee") all or a portion of its rights and obligations under this
Agreement (including, without limitation, all or a portion of its Revolving
Credit Commitments, the outstanding Loans made by it, the Note or Notes held by
it and its participations in Letters of Credit); provided, however, that (i) any
                                                 --------  -------
such assignment (other than an assignment to a Lender or an Affiliate of a
Lender) shall not be made without the prior written consent of the Agent and the
Borrower (to be evidenced by its counterexecution of the relevant Assignment and
Acceptance), which consent shall not be unreasonably withheld (provided that the
                                                               --------
Borrower's consent shall not be required in the event a Default or Event of
Default shall have occurred and be continuing), (ii) each such assignment shall
be of a uniform, and not varying, percentage of all of the assigning Lender's
rights and obligations under this Agreement, (iii) except in the case of an
assignment to a Lender or an Affiliate of a Lender, no such assignment shall be
in an aggregate principal amount (determined as of the date of the Assignment
and Acceptance with respect to such assignment) less than (y) in the case of
Revolving Credit Commitments, $2,500,000, determined by combining the amount of
the assigning Lender's outstanding Revolving Loans, Letter of Credit Exposure
and Unutilized Revolving Credit Commitment being assigned pursuant to such
assignment (or, if less, the entire Revolving Credit Commitment of the assigning
Lender), provided that in the Agent's discretion such amount may be reduced for
         --------
assignments made in connection with additions to the aggregate Revolving Credit
Commitments as provided for in Section 2.1(c), or (z) in the case of Swingline
Loans, the entire Swingline Commitment and the full amount of the outstanding
Swingline Loans, and (iv) the parties to each such assignment will execute and
deliver to the Agent, for its acceptance and recording in the Register, an
Assignment and Acceptance, together with any Note or Notes subject to such
assignment, and will pay a nonrefundable processing fee of $3,500 to the Agent
for its own account. Upon such execution, delivery, acceptance and recording of
the Assignment and Acceptance, from and after the effective date specified
therein, which effective date shall be at least five Business Days after the
execution thereof (unless the Agent shall otherwise agree), (A) the Assignee
thereunder shall be a party hereto and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such Assignment and
Acceptance, shall have the rights and obligations of the assigning Lender
hereunder with respect thereto and (B) the assigning Lender shall, to the extent
that rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Acceptance, from and after such assignment relinquish its rights
(other than rights under the provisions of this Agreement and the other Credit
Documents relating to indemnification or payment of fees, costs and expenses, to
the extent such rights relate to the time prior to the

                                       95
<PAGE>

effective date of such Assignment and Acceptance) and be released from its
obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of such assigning Lender's
rights and obligations under this Agreement, such Lender shall cease to be a
party hereto). The terms and provisions of each Assignment and Acceptance shall,
upon the effectiveness thereof, be incorporated into and made a part of this
Agreement, and the covenants, agreements and obligations of each Lender set
forth therein shall be deemed made to and for the benefit of the Agent and the
other parties hereto as if set forth at length herein.

     (b) The Agent will maintain at its address for notices referred to herein a
copy of each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Lenders and the
Revolving Credit Commitments of, and principal amount of the Loans owing to,
each Lender from time to time (the "Register"). The entries in the Register
shall be conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Agent and the Lenders may treat each Person whose name is recorded
in the Register as a Lender hereunder for all purposes of this Agreement. The
Register shall be available for inspection by the Borrower and each Lender at
any reasonable time and from time to time upon reasonable prior notice.

     (c) Upon its receipt of a duly completed Assignment and Acceptance executed
by an assigning Lender and an Assignee and, if required, counterexecuted by the
Borrower, together with the Note or Notes subject to such assignment and the
processing fee referred to in subsection (a) above, the Agent will (i) accept
such Assignment and Acceptance, (ii) on the effective date thereof, record the
information contained therein in the Register and (iii) give notice thereof to
the Borrower and the Lenders. Within five (5) Business Days after its receipt of
such notice, the Borrower, at its own expense, will execute and deliver to the
Agent, in exchange for the surrendered Note or Notes, a new Note or Notes to the
order of the Assignee (and, if the assigning Lender has retained any portion of
its rights and obligations hereunder, to the order of the assigning Lender),
prepared in accordance with the applicable provisions of Section 2.4 as
necessary to reflect, after giving effect to the assignment, the Revolving
Credit Commitments of the Assignee and (to the extent of any retained interests)
the assigning Lender, dated the date of the replaced Note or Notes and otherwise
in substantially the form of Exhibits A-1 and A-2, as applicable. The Agent will
return canceled Notes to the Borrower.

     (d) Each Lender may, without the consent of the Borrower, the Agent or any
other Lender, sell to one or more other Persons (each, a "Participant")
participations in all or any portion of its rights and obligations under this
Agreement (including, without limitation, a portion of its Revolving Credit
Commitments, the outstanding Loans made by it, the Note or Notes held by it and
its participations in Letters of Credit); provided, however, that (i) such
                                          --------  -------
Lender's obligations under this Agreement shall remain unchanged and such Lender
shall remain solely responsible for the performance of such obligations, (ii)
the Borrower, the Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, and no Lender shall permit any Participant to
have any voting rights or any right to control the vote of such Lender with
respect to any amendment, modification, waiver, consent or other action
hereunder or under any other Credit Document (except as to actions, to the
extent such actions affect the rights of such Participant, that would (x) reduce
or forgive the principal amount of any Loan, reduce the rate of or forgive any
interest thereon, or reduce or forgive any fees or other Obligations, (y) extend
the Maturity

                                       96
<PAGE>

Date or any other date fixed for the payment of any principal of or interest on
any Loan, any fees or any other Obligations, or (z) increase or extend the
Revolving Credit Commitment of any Lender, it being understood that a waiver of
any Default or Event of Default, if agreed to by the requisite Lenders
hereunder, shall not constitute such an increase), and (iii) no Participant
shall have any rights under this Agreement or any of the other Credit Documents,
each Participant's rights against the granting Lender in respect of any
participation to be those set forth in the participation agreement, and all
amounts payable by the Borrower hereunder shall be determined as if such Lender
had not granted such participation. Notwithstanding the foregoing, each
Participant shall have the rights of a Lender for purposes of Sections 2.16(a),
2.16(b), 2.17, 2.18 and 9.3, and shall be entitled to the benefits thereto, to
the extent that the Lender granting such participation would be entitled to such
benefits if the participation had not been made, provided that no Participant
                                                 --------
shall be entitled to receive any greater amount pursuant to any of such Sections
than the Lender granting such participation would have been entitled to receive
in respect of the amount of the participation made by such Lender to such
Participant had such participation not been made.

     (e) Nothing in this Agreement shall be construed to prohibit any Lender
from pledging or assigning all or any portion of its rights and interest
hereunder or under any Note to any Federal Reserve Bank as security for
borrowings therefrom; provided, however, that no such pledge or assignment shall
                      --------  -------
release a Lender from any of its obligations hereunder.

     (f) Any Lender or Participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section,
disclose to the Assignee or Participant or proposed Assignee or Participant any
information relating to the Borrower and its Subsidiaries furnished to it by or
on behalf of any other party hereto, provided that such Assignee or Participant
                                     --------
or proposed Assignee or Participant agrees in writing for the express benefit of
the Borrower to keep such information confidential to the same extent required
of the Lenders under Section 11.13.

     11.8 No Waiver. The rights and remedies of the Agent and the Lenders
          ---------
expressly set forth in this Agreement and the other Credit Documents are
cumulative and in addition to, and not exclusive of, all other rights and
remedies available at law, in equity or otherwise. No failure or delay on the
part of the Agent or any Lender in exercising any right, power or privilege
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right, power or privilege preclude other or further exercise thereof or
the exercise of any other right, power or privilege or be construed to be a
waiver of any Default or Event of Default. No course of dealing between any of
the Borrower and the Agent or the Lenders or their agents or employees shall be
effective to amend, modify or discharge any provision of this Agreement or any
other Credit Document or to constitute a waiver of any Default or Event of
Default. No notice to or demand upon the Borrower in any case shall entitle the
Borrower to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the right of the Agent or any Lender to
exercise any right or remedy or take any other or further action in any
circumstances without notice or demand.

     11.9 Successors and Assigns. This Agreement shall be binding upon, inure to
          ----------------------
the benefit of and be enforceable by the respective successors and permitted
assigns of the parties hereto, and all references herein to any party shall be
deemed to include its successors

                                       97
<PAGE>

and permitted assigns; provided, however, that (i) the Borrower shall not sell,
                       --------  -------
assign or transfer any of its rights, interests, duties or obligations under
this Agreement without the prior written consent of all of the Lenders and (ii)
any Assignees and Participants shall have such rights and obligations with
respect to this Agreement and the other Credit Documents as are provided for
under and pursuant to the provisions of Section 11.7.

     11.10 Survival. All representations, warranties and agreements made by or
           --------
on behalf of the Borrower or any of its Subsidiaries in this Agreement and in
the other Credit Documents shall survive the execution and delivery hereof or
thereof, the making and repayment of the Loans and the issuance and repayment of
the Letters of Credit. In addition, notwithstanding anything herein or under
applicable law to the contrary, the provisions of this Agreement and the other
Credit Documents relating to indemnification or payment of fees, costs and
expenses, including, without limitation, the provisions of Sections 2.16(a),
2.16(b), 2.17, 2.18, 10.7, 11.1 and 11.2, shall survive the payment in full of
all Loans and Letters of Credit, the termination of the Revolving Credit
Commitments and all Letters of Credit, and any termination of this Agreement or
any of the other Credit Documents.

     11.11 Severability. To the extent any provision of this Agreement is
           ------------
prohibited by or invalid under the applicable law of any jurisdiction, such
provision shall be ineffective only to the extent of such prohibition or
invalidity and only in such jurisdiction, without prohibiting or invalidating
such provision in any other jurisdiction or the remaining provisions of this
Agreement in any jurisdiction.

     11.12 Construction. The headings of the various articles, sections and
           ------------
subsections of this Agreement have been inserted for convenience only and shall
not in any way affect the meaning or construction of any of the provisions
hereof. Except as otherwise expressly provided herein and in the other Credit
Documents, in the event of any inconsistency or conflict between any provision
of this Agreement and any provision of any of the other Credit Documents, the
provision of this Agreement shall control.

     11.13 Confidentiality. Each Lender agrees to keep confidential pursuant to
           ---------------
its customary procedures for handling confidential information of a similar
nature and in accordance with safe and sound banking practices, all nonpublic
information provided to it by or on behalf of the Borrower or any of its
Subsidiaries in connection with this Agreement or any other Credit Document;
provided, however, that any Lender may disclose such information (i) to its
--------  -------
directors, employees and agents and to its auditors, counsel and other
professional advisors, that have a reasonable need for access thereto, (ii) at
the demand or request of any bank regulatory authority, court or other
Governmental Authority having or asserting jurisdiction over such Lender, as may

appropriate reference to the fact that the Collateral has been assigned to the
Collateral Agent and that the Collateral Agent has a security interest therein.

of all rent due and payable under each lease) and enforce the terms and
provisions thereof in accordance with its terms to the extent consistent with
sound business practices, and will not waive, amend or modify any provision
thereof in any manner other than in the ordinary course of business of such
Pledgor in accordance with past practice or for a valid economic reason
benefiting such Pledgor. Each Pledgor will deliver copies of each Specified
Contract to which it is a party and each material amendment or modification
thereof to the Collateral Agent promptly upon the execution and delivery
thereof. With regard to all leases, contracts and agreements that are excluded
from the definition of the term "Contracts," each Pledgor covenants and agrees
to exercise all of its material rights and remedies under such leases,
agreements and contracts to which it is a party in a commercially reasonable
manner to the extent consistent with sound business practices. Except as

rights and interest thereunder in the manner contemplated by this

                                       16
<PAGE>

property leases and Licenses), in form and substance reasonably satisfactory to
the Collateral Agent, upon the request of the Collateral Agent, and will deliver
copies thereof to the Collateral Agent promptly upon execution and delivery
thereof. Each Pledgor further covenants and agrees to use its commercially
reasonable efforts to obtain any required consent to the collateral assignment
of any Material Contract, in form and substance reasonably satisfactory to the
Collateral Agent, upon the reasonable request of the Collateral Agent, and will
deliver copies thereof to the Collateral Agent promptly upon execution and
delivery thereof.

         -----
and governmental charges or levies imposed upon it, upon its income or profits
or upon any of its properties, prior to the date on which penalties would attach
thereto, and (ii) all lawful claims that, if unpaid, might become a Lien upon
any of its properties; provided, however, that no Pledgor shall be required to
                       --------  -------
pay any such tax, assessment, charge, levy or claim that is being contested in
good faith and by proper proceedings and as to which such Pledgor has maintained
adequate reserves with respect thereto in accordance with GAAP unless and until
any tax lien notice has become effective with respect thereto or until any Lien
resulting therefrom attaches to its properties and becomes enforceable against
its other creditors.

     4.10 Insurance.
          ---------

     (a) Each Pledgor will maintain and pay for, or cause to be maintained and
paid for, insurance covering commercial general liability, property and
casualty, business interruption and such other risks, and in such amounts and
with such financially sound and reputable insurance companies, as are usually
and customarily carried by companies of similar size engaged in similar
businesses (and in any event, insuring all Inventory and Equipment against such
losses and risks), and will deliver certificates of such insurance to the
Collateral Agent with standard loss payable endorsements naming the Collateral
Agent as loss payee (on property and casualty policies) and additional insured
(on liability policies) as its interests may appear. Each such policy of
insurance shall contain a clause requiring the insurer to give not less than 30
days' prior written notice to the Collateral Agent before any cancellation of
the policies for any reason whatsoever and shall provide that any loss shall be
payable in accordance with the terms thereof notwithstanding any act of any
Pledgor that might result in the forfeiture of such insurance.

     (b) Each Pledgor will direct all insurers under policies of property and
casualty insurance on the Collateral to pay all proceeds payable thereunder
directly to the Collateral Agent (and the receipt of such proceeds by the
Collateral Agent shall be deemed as received by the Borrower for purposes of
Section 2.6(d) of the Credit Agreement). The Collateral Agent shall hold all
such proceeds in excess of $3,000,000 for the account of the Pledgors, except
that upon the occurrence and during the continuance of any Default or Event of
Default the Collateral Agent shall hold all of such proceeds. So long as no
Event of Default has occurred and is continuing, and subject to any applicable
provision of the Credit Agreement requiring the prepayment of the Loans with the
proceeds of such insurance, the Collateral Agent shall, at the Borrower's
request, disburse such proceeds as payment for the purpose of replacing or
repairing destroyed or damaged assets, as and when required to be paid and upon
presentation of evidence

                                       17
<PAGE>

satisfactory to the Collateral Agent of such required payments and such other
documents as the Collateral Agent may reasonably request. As and to the extent
required by the Credit Agreement, but subject to the terms of the Intercreditor
Agreement and in any event upon and during the continuance of an Event of
Default, the Collateral Agent shall apply such proceeds in the manner provided
for in Section 6.2 hereof. Each Pledgor hereby irrevocably makes, constitutes
and appoints the Collateral Agent at all times during the continuance of an
Event of Default, its true and lawful attorney (and agent-in-fact) for the
purpose of making, settling and adjusting claims under such policies of
insurance, endorsing its name on any check, draft, instrument or other item or
payment for the proceeds of such policies of insurance and for making all
determinations and decisions with respect to such policies of insurance.

     (c) If any Pledgor fails to obtain and maintain any of the policies of
insurance required to be maintained hereunder or to pay any premium in whole or
in part, the Collateral Agent may, without waiving or releasing any obligation
or Default, at the Pledgors' expense, but without any obligation to do so,
procure such policies or pay such premiums. All sums so disbursed by the
Collateral Agent, including attorneys' fees, court costs, expenses and other
charges related thereto, shall be payable by the Pledgors to the Collateral
Agent on demand and shall be additional Secured Obligations hereunder, secured
by the Collateral.

     (d) Each Pledgor will deliver to the Collateral Agent, promptly as
rendered, true copies of all material claims and reports made in any reporting
forms to insurance companies. Not less than 30 days prior to the expiration date
of the insurance policies required to be maintained by such Pledgor hereunder,
such Pledgor will deliver to the Collateral Agent one or more certificates of
insurance evidencing renewal of the insurance coverage required hereunder plus
such other evidence of payment of premiums therefor as the Collateral Agent may
reasonably request. Upon the reasonable request of the Collateral Agent from
time to time, each Pledgor will deliver to the Collateral Agent evidence that
the insurance required to be maintained pursuant to this Section 4.10 is in
effect.

Collateral, Patent Collateral or Trademark Collateral, and the Registrant Name
Change Agreement, in the form of Annex A to Exhibit E with regard to any Domain

that after the date hereof any Pledgor shall acquire any registered Copyright,
Patent, Trademark or Domain Name or effect any registration of any Copyright,
Patent, Trademark or Domain Name, or file any application for registration
thereof, whether within the United States or any other country or jurisdiction,
such Pledgor shall promptly furnish written notice thereof to the Collateral
Agent together with information sufficient to permit the Collateral Agent, upon
its receipt of such notice, to (and each Pledgor hereby authorizes the
Collateral Agent to) modify this Agreement, as appropriate, by amending Annexes
D, E, F or G hereto or to add additional exhibits hereto to include any such
Copyright, Patent, Trademark or Domain Name that becomes part of the Collateral
under this Agreement, and such Pledgor shall additionally, at its own expense,
execute and deliver with regard to

grants of security interest in the forms of Exhibits B, C and E, as applicable,
together in all instances with any other agreements, instruments and documents

Agreement in such Copyrights, Patents, Trademarks and Domain Names, and each
Pledgor hereby appoints the Collateral Agent its attorney-in-fact to execute,
deliver and record any and all such agreements, instruments and documents for
the foregoing purposes, all acts of such attorney being hereby ratified and
confirmed and such power, being coupled with an interest, shall be irrevocable
for so long as this Agreement shall be in effect with respect to such Pledgor.

     (b) Each Pledgor (either itself or through its licensees or its
sublicensees) will, for each Trademark used in the conduct of its business, use
its commercially reasonable efforts to (i) maintain such Trademark in full force
and effect, free from any claim of abandonment or invalidity for non-use, (ii)
maintain the quality of products and services offered under such Trademark,
(iii) display such Trademark with notice of federal registration to the extent
required by applicable law (iv) take all necessary and appropriate steps to
police and defend such Trademark and prevent or arrest infringement, dilution or
other harm to such Trademark to the extent consistent with Pledgor's reasonable
business judgment and (v) not knowingly use or knowingly permit the use of such
Trademark in violation of any third-party rights.

     (c) Each Pledgor (either itself or through its licensees or sublicensees)
will consistent with its reasonable business judgment refrain from committing
any act, or omitting any act, whereby any Patent used in the conduct of such
Pledgor's business may become invalidated or dedicated to the public, and shall
continue to mark any products covered by a Patent with the relevant patent
number as required by applicable patent laws.

     (d) Each Pledgor (either itself or through its licensees or sublicensees)
will consistent with its reasonable business judgment, for each work covered by
a Copyright, continue to publish, reproduce, display, adopt and distribute the
work with appropriate copyright notice as required under applicable copyright
laws.

     (e) Each Pledgor shall notify the Collateral Agent immediately if it knows
or has reason to know that any material Patent, Trademark or Copyright used in
the conduct of its business may become abandoned or dedicated to the public, or
of any adverse determination or development (including the institution of, or
any such determination or development in, any proceeding in the U.S. Patent and
Trademark Office, U.S. Copyright Office or any court) regarding such Pledgor's
ownership of any material Patent, Trademark or Copyright, its right to register
the same, or to keep and maintain the same.

     (f) Each Pledgor will take all necessary or advisable steps in any
proceeding before the U.S. Patent and Trademark Office, U.S. Copyright Office or
any office or agency in any political subdivision of the United States or in any
other country or any political subdivision thereof, to maintain and pursue each
application relating to any material Patents, Trademarks or Copyrights useful
for its business or otherwise of material commercial value (and to obtain the
relevant grant or registration) and to maintain each registration of any
material Patents, Trademarks and Copyrights useful for its business or otherwise
of material commercial value,

                                       19
<PAGE>

including the filing of applications for renewal, affidavits of use, affidavits
of incontestability and maintenance fees, and, if consistent with its reasonable
business judgment, to initiate opposition, interference and cancellation
proceedings against third parties.

     (g) In the event that any Collateral consisting of a material Patent,
Trademark or Copyright useful in the conduct of any Pledgor's business or
otherwise of material commercial value is believed infringed, misappropriated or
diluted by a third party, such Pledgor shall notify the Collateral Agent
promptly after it learns thereof and shall, if consistent with its reasonable
business judgment, promptly sue for infringement, misappropriation or dilution

while an Event of Default shall have occurred and be continuing, each Pledgor
will deliver to the Collateral Agent originals of the certificates of title or
ownership for all Mobile Goods owned by it, together (in the case of motor
vehicles) with the manufacturer's statement of origin with the Collateral Agent
listed as lienholder and odometer statements and together in all other cases
with appropriate instruments or certificates of transfer and delivery, duly
completed and executed, and will take such other action as the Collateral Agent
may reasonably deem necessary to perfect the security interest created by this
Agreement in all such Mobile Goods.

     4.13 Collateral in Possession of Third Party. Without limiting the
          ---------------------------------------
generality of any other provision of this Agreement, each Pledgor agrees that it
shall not permit any Collateral to be in the possession of any bailee,
warehouseman, agent, processor or other third party at any time unless such
bailee or other Person shall have been notified of the security interest created
by this Agreement (or, if required under applicable law in order to perfect the
Collateral Agent's security interest in such Collateral, such bailee or other
Person shall have acknowledged to the Collateral Agent in writing that it is
holding such Collateral for the benefit of the Collateral Agent and subject to
such security interest and to the instructions of the Collateral Agent) and such
Pledgor shall have exercised its commercially reasonable efforts to obtain from
such bailee or other Person, at such Pledgor's sole cost and expense, the
written acknowledgement described above (if not already required by applicable
law to perfect the Collateral Agent's security interest), such agreement to be
in form and substance reasonably satisfactory to the Collateral Agent.

     4.14 Deposit and Collection Procedures Upon an Event of Default. If an
          ----------------------------------------------------------
Event of Default shall have occurred and be continuing for a period of 30
consecutive days, each Pledgor will execute all such documents and agreements
and take all such actions as are necessary to ensure that all proceeds of
Accounts (including Medicare, Medicaid and other similar Accounts payable by
Governmental Authorities ("Governmental Accounts")), remitted to it or any of
                           ---------------------
its Subsidiaries or affiliated physician practices are deposited, promptly upon
such Person's receipt thereof, directly into a deposit account controlled and
directed by the Borrower or any of its

                                       20
<PAGE>

Subsidiaries or such other Person (including any applicable provider as may be
required with respect to Governmental Accounts), and that the balances in each
such deposit account not maintained by any Pledgor are transferred daily into a
deposit account maintained by or for the benefit of a Pledgor or into a
Concentration Account (as defined below). The balances in each such deposit
account of a Pledgor shall be transferred daily to a cash concentration account
maintained with the Collateral Agent or with another bank or depository
institution that has, together with the such Pledgor, executed and delivered to
the Collateral Agent a duly completed agreement, in form and substance
reasonably satisfactory to the Collateral Agent, that among other things
acknowledges the security interest of the Collateral Agent in all funds, monies,
securities and instruments deposited in such account and pursuant to which such
bank or depository institution agrees to transfer such funds, monies, securities
and instruments to the Collateral Agent promptly upon demand at any time after
the occurrence and during the continuance of an Event of Default (each such
account, a "Concentration Account," and each such agreement, a "Concentration
            ---------------------                               -------------
Agreement") for application to the Secured Obligations then due and payable in
---------
accordance with Section 6.2. The applicable Pledgor will provide each bank or
depository institution at which any Deposit Account is maintained from time to
time with such transfer instructions and other information as such bank or
depository institution may require in order to permit the Pledgor to comply with
the provisions of this Section. All costs and expenses incurred in connection
with the establishment and maintenance of such Deposit Accounts and
Concentration Accounts and the transfers of funds therefrom and thereto as
described in this Section shall be for the account of the Pledgor. Except as
expressly provided in this Section 4.14, no proceeds of Accounts will be
deposited in, or at any time transferred to, a Deposit Account other than a
Concentration Account or a Deposit Account the balances in which are transferred
not less frequently than daily to a Concentration Account. The Pledgors shall
not cause or permit any funds or other property not constituting proceeds of
Collateral to be deposited into any Deposit Account containing proceeds of
Collateral. The Pledgors shall have the right to collect, withdraw and direct
the disposition of funds on deposit in the Concentration Accounts in a manner
not inconsistent with the provisions of this Agreement or any of the other Loan
Documents; provided, however, that during the continuance of an Event of Default
           --------  -------
and after notice thereof from the Collateral Agent to the Borrower, the
Collateral Agent shall have exclusive dominion and control over all
Concentration Accounts, with the powers and rights granted herein and in the
applicable Concentration Agreements with respect thereto, and the Pledgors shall
not have any right without the consent of the Collateral Agent to collect,
withdraw or direct the disposition of funds on deposit in the Concentration
Accounts or to take any action to effect the same. Any failure by the Pledgors
to observe, perform or comply with any provision of this Section shall
constitute an Event of Default under the Loan Agreement. Notwithstanding the
foregoing, any part or all of the requirements of this Section may be waived at
any time or times by the Required Secured Parties.

     4.15 Control Agreements. Upon the request of the Collateral Agent, each
          ------------------
Pledgor will, at its own cost and expense, cooperate with the Collateral Agent
in obtaining a control agreement, in form and substance reasonably satisfactory
to the Collateral Agent, and in taking such other actions as may be reasonably
requested by the Collateral Agent from time to time with respect to any
Investment Property or other Collateral in which a security interest may be
perfected by (or can be perfected only by) control under the Uniform Commercial
Code.

     4.16 Protection of Security Interest. Each Pledgor agrees that it will, at
          -------------------------------
its own cost and expense, take any and all actions reasonably necessary to
warrant and defend the right, title and interest of the Secured Parties in and
to the Collateral against the claims and demands of all other Persons.

                 PLEDGED INTERESTS AND INTERCOMPANY OBLIGATIONS

     5.1 Ownership; After-Acquired Pledged Interests.
         -------------------------------------------

     (a) Except to the extent otherwise expressly permitted by or pursuant to
the Credit Agreement and the Operative Agreements, each Pledgor will cause the
Pledged Interests in each issuer pledged hereunder to constitute at all times
100% of the capital stock or other Pledged Interests in each issuer such that
the issuer shall be a Wholly Owned Subsidiary of the Borrower, and unless the
Collateral Agent shall have given its prior written consent, no Pledgor will
cause or permit any such issuer to issue or sell any new capital stock, any
warrants, options or rights to acquire the same, or other Pledged Interests of
any nature to any Person other than such Pledgor, or cause, permit or consent to
the admission of any other Person as stockholder, partner or member of any such
issuer.

     (b) If any Pledgor shall, at any time and from time to time after the date
hereof, acquire any additional capital stock or other Pledged Interests in any
Person of the types described in the definition of the term "Pledged Interests,"
or any promissory notes or other instruments evidencing indebtedness or other
obligations of the types described in the definition of "Intercompany
Obligations," the same shall be automatically deemed to be Pledged Interests or
Intercompany Obligations hereunder, respectively, and to be pledged to the
Collateral Agent pursuant to Section 2.1, and such Pledgor will forthwith pledge
and deposit the same with the Collateral Agent and deliver to the Collateral
Agent any certificates or instruments therefor, together with the endorsement of
such Pledgor (in the case of any promissory notes or other Instruments), undated
stock powers (in the case of Pledged Interests evidenced by certificates) or
other necessary instruments of transfer or assignment, duly executed in blank
and in form and substance reasonably satisfactory to the Collateral Agent,
together with such other certificates and instruments as the Collateral Agent
may reasonably request (including Uniform Commercial Code financing statements
or appropriate amendments thereto), and will promptly thereafter deliver to the
Collateral Agent a fully completed and duly executed amendment to this Agreement
in the form of Exhibit A (each, a "Pledge Amendment") in respect thereof. Each
                                   ----------------
Pledgor hereby authorizes the Collateral Agent to attach each such Pledge
Amendment to this Agreement, and agrees that all such Collateral listed on any
Pledge Amendment shall for all purposes be deemed Collateral hereunder and shall
be subject to the provisions hereof; provided that the failure of any Pledgor to
                                     --------
execute and deliver any Pledge Amendment with respect to any such additional
Collateral as required hereinabove shall not impair the security interest of the
Collateral Agent in such Collateral or otherwise adversely affect the rights and
remedies of the Collateral Agent hereunder with respect thereto.

                                       22

     (c) If any Pledged Interests (whether now owned or hereafter acquired)
included in the Collateral are "uncertificated securities" within the meaning of
the Uniform Commercial Code or are otherwise not evidenced by any certificate or
instrument, each applicable Pledgor will promptly notify the Collateral Agent
thereof and will promptly take and cause to be taken, and will (if the issuer of
such uncertificated securities is a Person other than a Subsidiary of the
Borrower) use its commercially reasonable efforts to cause the issuer to take,
all actions required under Articles 8 and 9 of the Uniform Commercial Code and
any other applicable law, to enable the Collateral Agent to acquire "control" of
such uncertificated securities (within the meaning of such term under Section
8-106 (or its successor provision) of the Uniform Commercial Code) and as may be
otherwise necessary or reasonably deemed appropriate by the Collateral Agent to
perfect the security interest of the Collateral Agent therein.

     5.2 Voting Rights. So long as no Event of Default shall have occurred and
         -------------
be continuing each Pledgor shall be entitled to exercise all voting and other
consensual rights pertaining to its Pledged Interests (subject to its
obligations under Section 5.1), and for that purpose the Collateral Agent will
execute and deliver or cause to be executed and delivered to each applicable
Pledgor all such proxies and other instruments as such Pledgor may reasonably
request in writing to enable the Pledgor to exercise such voting and other
consensual rights; provided, however, that to the extent permitted by applicable
                   --------  -------
law Pledgor will not cast any vote, give any consent, waiver or ratification, or
take or fail to take any action, in any manner that would, or could reasonably
be expected to, violate or be inconsistent with any of the terms of this
Agreement, the Credit Agreement, any other Credit Document or any Operative
Agreement, or have the effect of materially impairing the position or interests
of the Collateral Agent or any other Secured Party (except to the extent
permitted under any Credit Document).

     5.3 Dividends and Other Distributions. So long as no Event of Default shall
         ---------------------------------
have occurred and be continuing (or would occur as a result thereof), and except
as provided otherwise herein, all interest, income, dividends, distributions and
other amounts payable in cash in respect of the Pledged Interests may be paid to
and retained by the Pledgors; provided, however, that all such interest, income,
                              --------  -------
dividends, distributions and other amounts shall, at all times after the
occurrence and during the continuance of an Event of Default, be paid to the
Collateral Agent and retained by it as part of the Collateral (except to the
extent applied upon receipt to the repayment of the Secured Obligations then due
and payable). The Collateral Agent shall also be entitled at all times (whether
or not during the continuance of an Event of Default) to receive directly, and
to retain as part of the Collateral, (i) all interest, income, dividends,
distributions or other amounts paid or payable in cash or other property in
respect of any Pledged Interests in connection with the dissolution,
liquidation, recapitalization or reclassification of the capital of the
applicable issuer to the extent representing an extraordinary, liquidating or
other distribution in return of capital that is not permitted under the Credit
Agreement, (ii) all additional Pledged Interests or other securities or property
(other than cash) paid or payable or distributed or distributable in respect of
any Pledged Interests in connection with any noncash dividend, distribution,
return of capital, spin-off, stock split, split-up, reclassification,
combination of shares or interests or similar rearrangement, and (iii) without
affecting any restrictions against such actions contained in the Credit
Agreement or any Operative Agreement , all additional Pledged Interests or other
securities or property (including cash) paid or payable or distributed or
distributable in respect of any Pledged Interests in connection with any
consolidation, merger, exchange of securities, liquidation or other
reorganization except those

                                       23
<PAGE>

paid, payable, distributed or distributable pursuant to any such transaction
permitted by the Credit Agreement. All interest, income, dividends,
distributions or other amounts that are received by any Pledgor in violation of
the provisions of this Section 5.3 shall be received in trust for the benefit of
the Collateral Agent, shall be segregated from other property or funds of such
Pledgor and shall be forthwith delivered to the Collateral Agent as Collateral
in the same form as so received (with any necessary endorsements) for
application to reduce the Secured Obligation then due and payable.

                                   ARTICLE VI

                                    REMEDIES

     6.1 Remedies. If an Event of Default shall have occurred and be continuing,
         --------
the Collateral Agent shall be entitled to exercise in respect of the Collateral
all of its rights, powers and remedies provided for herein, by law, in equity or
otherwise, including all rights and remedies of a secured party under the
Uniform Commercial Code, and shall be entitled in particular, but without
limitation of the foregoing, to exercise the following rights, which each
Pledgor agrees to be commercially reasonable:

     (a) To notify any or all account debtors or obligors under any Accounts,
Contracts or other Collateral of the security interest in favor of the
Collateral Agent created hereby and to direct all such Persons to make payments
of all amounts due thereon or thereunder directly to the Collateral Agent or to
an account designated by the Collateral Agent; and in such instance and from and
after such notice, all amounts and Proceeds (including wire transfers, checks
and other instruments) received by any Pledgor in respect of any Accounts,
Contracts or other Collateral shall be received in trust for the benefit of the
Collateral Agent hereunder, shall be segregated from the other funds of such
Pledgor and shall be forthwith deposited into such account or paid over or
delivered to the Collateral Agent in the same form as so received (with any
necessary endorsements or assignments), to be held as Collateral and applied to
the Secured Obligations then due and payable as provided herein; and by this
provision, each Pledgor irrevocably authorizes and directs each Person who is or
shall be a party to or liable for the performance of any Contract, upon receipt
of notice from the Collateral Agent to the effect that an Event of Default has
occurred and is continuing, to attorn to or otherwise recognize the Collateral
Agent as owner under such Contract and to pay, observe and otherwise perform the
obligations under such Contract to or for the Collateral Agent or the Collateral
Agent's designee as though the Collateral Agent or such designee were such
Pledgor named therein, and to do so until otherwise notified by the Collateral
Agent;

     (b) To take possession of, receive, endorse, assign and deliver, in its own
name or in the name of any Pledgor, all checks, notes, drafts and other
instruments relating to any Collateral, including receiving, opening and
properly disposing of all mail addressed to any Pledgor concerning Accounts and
other Collateral and to notify the appropriate postal authority to change the
mailing or delivery address of such mail; to verify with account debtors or
other contract parties the validity, amount or any other matter relating to any
Accounts or other Collateral, in its own name or in the name of any Pledgor; to
accelerate any indebtedness or other obligation constituting Collateral that may
be accelerated in accordance with its terms; to take or

                                       24
<PAGE>

bring all actions and suits deemed necessary or appropriate to effect
collections and to enforce payment of any Accounts or other Collateral; to
settle, compromise or release in whole or in part any amounts owing on Accounts
or other Collateral; and to extend the time of payment of any and all Accounts
or other amounts owing under any Collateral and to make allowances and
adjustments with respect thereto, all in the same manner and to the same extent
as any Pledgor might have done;

     (c) To notify any or all depository institutions with which any Deposit
Accounts are maintained to remit and transfer all monies, securities and other
property on deposit in such Deposit Accounts or deposited or received for
deposit thereafter to the Collateral Agent, for deposit in a Collateral Account
or such other accounts as may be designated by the Collateral Agent, for
application to the Secured Obligations then due and payable as provided herein;

     (d) To transfer to or register in its name or the name of any of its agents
or nominees all or any part of the Collateral, with or without disclosing that
such Collateral is subject to the security interest created hereunder;

     (e) To require any Pledgor to, and each Pledgor hereby agrees that it will
at its expense and upon request of the Collateral Agent forthwith, assemble all
or any part of the Collateral as directed by the Collateral Agent and make it
available to the Collateral Agent at a place designated by the Collateral Agent;

     (f) To enter upon the premises of any Pledgor and take possession of all or
any part of the Collateral, with or without judicial process; to use the
materials, services, books and records of any Pledgor for the purpose of
liquidating or collecting the Collateral, whether by foreclosure, auction or
otherwise; and to remove the same to the premises of the Collateral Agent or any
designated agent for such time as the Collateral Agent may desire, in order to
effectively collect or liquidate the Collateral;

     (g) To exercise (i) all voting, consensual and other rights and powers
pertaining to the Pledged Interests (whether or not transferred into the name of
the Collateral Agent), at any meeting of shareholders, partners, members or
otherwise, and (ii) any and all rights of conversion, exchange, subscription and
any other rights, privileges or options pertaining to the Pledged Interests as
if it were the absolute owner thereof (including without limitation the right to
exchange at its discretion any and all of the Pledged Interests upon the merger,
consolidation, reorganization, reclassification, combination of shares or
interests, similar rearrangement or other similar fundamental change in the
structure of the applicable issuer, or upon the exercise by any Pledgor or the
Collateral Agent of any right, privilege or option pertaining to such Pledged
Interests), and in connection therewith, the right to deposit and deliver any
and all of the Pledged Interests with any committee, depositary, transfer agent,
registrar or other designated agency upon such terms and conditions as the
Collateral Agent may determine, and give all consents, waivers and ratifications
in respect of the Pledged Interests, but the Collateral Agent shall have no duty
to exercise any such right, privilege or option or give any such consent, waiver
or ratification and shall not be responsible for any failure to do so or delay
in so doing; and for the foregoing purposes each Pledgor will promptly execute
and deliver or cause to be executed and delivered to the Collateral Agent, upon
request, all such proxies and other instruments as the Collateral Agent may
request to enable the Collateral Agent to exercise such rights and powers;

                                       25
<PAGE>

AND IN FURTHERANCE OF THE FOREGOING AND WITHOUT LIMITATION THEREOF, EACH PLEDGOR
HEREBY IRREVOCABLY CONSTITUTES AND APPOINTS THE COLLATERAL AGENT AS THE TRUE AND
LAWFUL PROXY AND ATTORNEY-IN-FACT OF SUCH PLEDGOR, WITH FULL POWER OF
SUBSTITUTION IN THE PREMISES, TO EXERCISE ALL SUCH VOTING, CONSENSUAL AND OTHER
RIGHTS AND POWERS TO WHICH ANY HOLDER OF ANY INVESTMENTS WOULD BE ENTITLED BY
VIRTUE OF HOLDING THE SAME, WHICH PROXY AND POWER OF ATTORNEY, BEING COUPLED
WITH AN INTEREST, IS IRREVOCABLE AND SHALL BE EFFECTIVE FOR SO LONG AS THIS
AGREEMENT SHALL BE IN EFFECT;

     (h) To sell, resell, assign and deliver, in its sole discretion, all or any
of the Collateral, in one or more parcels, on any securities exchange on which
any Pledged Interests may be listed, at public or private sale, at any of the
Collateral Agent's offices or elsewhere, for cash, upon credit or for future
delivery, at such time or times and at such price or prices and upon such other
terms as the Collateral Agent may deem satisfactory. If any of the Collateral is
sold by the Collateral Agent upon credit or for future delivery, the Collateral
Agent shall not be liable for the failure of the purchaser to purchase or pay
for the same and, in the event of any such failure, the Collateral Agent may
resell such Collateral. In no event shall any Pledgor be credited with any part
of the Proceeds of sale of any Collateral until and to the extent cash payment
in respect thereof has actually been received by the Collateral Agent. Each
purchaser at any such sale shall hold the property sold absolutely, free from
any claim or right of whatsoever kind, including any equity or right of
redemption of any Pledgor, and to the extent permitted by law each Pledgor
hereby expressly waives all rights of redemption, stay or appraisal, and all
rights to require the Collateral Agent to marshal any assets in favor of such
Pledgor or any other party or against or in payment of any or all of the Secured
Obligations, that it has or may have under any rule of law or statute now
existing or hereafter adopted. To the extent permitted by law no demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law, as referred to below), all of which are hereby expressly waived
by each Pledgor, shall be required in connection with any sale or other
disposition of any part of the Collateral. If any notice of a proposed sale or
other disposition of any part of the Collateral shall be required under
applicable law, the Collateral Agent shall give the applicable Pledgor at least
10 days' prior notice of the time and place of any public sale and of the time
after which any private sale or other disposition is to be made, which notice
each Pledgor agrees is commercially reasonable. The Collateral Agent shall not
be obligated to make any sale of Collateral if it shall determine not to do so,
regardless of the fact that notice of sale may have been given. The Collateral
Agent may, without notice or publication, adjourn any public or private sale or
cause the same to be adjourned from time to time by announcement at the time and
place fixed for sale, and such sale may, without further notice, be made at the
time and place to which the same was so adjourned. Upon each public sale and, to
the extent permitted by applicable law, upon each private sale, the Collateral
Agent may purchase all or any of the Collateral being sold, free from any
equity, right of redemption or other claim or demand, and may make payment
therefor by endorsement and application (without recourse) of the Secured
Obligations in lieu of cash as a credit on account of the purchase price for
such Collateral;

     (i) To transfer or register in its name or in the names of any of its
agents or nominees, all or any part of the Domain Names, with or without
disclosing that such Collateral is subject to the security interest created
hereunder, by using the Registrant Name Change

                                       26
<PAGE>

Agreement, attached as Schedule A to the Grant of Security Interest in Domain
Name Registration previously delivered by the applicable Pledgor to the
Collateral Agent pursuant to Section 4.11; and

     (j) To accelerate any Intercompany Obligation that may be accelerated in
accordance with its terms, and take or bring all actions and suits deemed
necessary or appropriate to effect the collection thereof, all in the same
manner and to the same extent as any Pledgor might have done.

     6.2 Application of Proceeds. After the occurrence and during the
         -----------------------
continuation of an Event of Default:

     (a) All Proceeds collected by the Collateral Agent upon any sale, other
disposition of or realization upon any of the Collateral, together with all
other moneys received by the Collateral Agent hereunder, shall be applied as
follows:

          (i) first, to the payment of all costs and expenses of such sale,
     disposition or other realization, including the costs and expenses of the
     Collateral Agent and the fees and expenses of its agents and counsel, all
     amounts advanced by the Collateral Agent for the account of any Pledgor,
     and all other amounts payable to the Collateral Agent under Section 8.1;

          (ii) second, after payment in full of the amounts specified in clause
     (i) above, to the ratable payment of all other Secured Obligations then due
     and payable owing to the Secured Parties, together with the cash
     collateralization of any Letter of Credit Exposure pursuant to Section 3.8
     of the Credit Agreement (such payments to be made in accordance with the
     Intercreditor Agreement); and

          (iii) third, after payment in full of the amounts specified in clauses
     (i) and (ii) above, and following the termination of this Agreement, to the
     Pledgors or any other Person lawfully entitled to receive such surplus.

     (b) For purposes of applying amounts in accordance with this Section 6.2,
the Collateral Agent shall be entitled to rely upon any Secured Party that has
entered into a Hedge Agreement with the Borrower for a determination (which such
Secured Party agrees to provide or cause to be provided upon request of the
Collateral Agent) of the outstanding Secured Obligations owed to such Secured
Party under any such Hedge Agreement. Unless it has actual knowledge (including
by way of written notice from any such Secured Party) to the contrary, the
Collateral Agent, in acting hereunder, shall be entitled to assume that no Hedge
Agreements or Secured Obligations in respect thereof are in existence between
any Secured Party and the Borrower. If any Lender that is a party to a Hedge
Agreement with the Borrower (the obligations of the Borrower under which are
Secured Obligations) ceases to be a Lender, such former Lender shall
nevertheless continue to be a Secured Party hereunder with respect to the
Secured Obligations under such Hedge Agreement.

     (c) Each Pledgor shall remain liable to the extent of any deficiency
between the amount of all Proceeds realized upon sale or other disposition of
the Collateral pursuant to this Agreement and the aggregate amount of the sums
referred to in Section 6.2(a)(i) and (ii). Upon

                                       27
<PAGE>

any sale of any Collateral hereunder by the Collateral Agent (whether by virtue
of the power of sale herein granted, pursuant to judicial proceeding, or
otherwise), the receipt of the Collateral Agent or the officer making the sale
shall be a sufficient discharge to the purchaser or purchasers of the Collateral
so sold, and such purchaser or purchasers shall not be obligated to see to the
application of any part of the purchase money paid over to the Collateral Agent
or such officer or be answerable in any way for the misapplication thereof.

     6.3 Collateral Accounts. Upon the occurrence and during the continuance of
         -------------------
an Event of Default, the Collateral Agent shall have the right to cause to be
established and maintained, at its principal office or such other location or
locations as it may establish from time to time in its discretion, one or more
accounts (collectively, "Collateral Accounts") for the collection of cash
                         -------------------
Proceeds of the Collateral. Such Proceeds, when deposited, shall continue to
constitute Collateral for the Secured Obligations and shall not constitute
payment thereof until applied as herein provided. The Collateral Agent shall
have sole dominion and control over all funds deposited in any Collateral
Account, and such funds may be withdrawn therefrom only by the Collateral Agent.
Upon the occurrence and during the continuance of an Event of Default, the
Collateral Agent shall have the right to (and, if directed by the Required
Secured Parties shall) apply amounts held in the Collateral Accounts in payment
of the Secured Obligations in the manner provided for in Section 6.2.

     6.4 Grant of License. Each Pledgor hereby grants to the Collateral Agent an
         ----------------
irrevocable, non-exclusive license (exercisable without payment of royalty or
other compensation to any Pledgor) to use, license or sublicense any Patent
Collateral, Trademark Collateral or Copyright Collateral now owned or licensed
or hereafter acquired or licensed by such Pledgor, wherever the same may be
located throughout the world, for such term or terms, on such conditions and in
such manner as the Collateral Agent shall determine, whether general, special or
otherwise, and whether on an exclusive or nonexclusive basis, and including in
such license access to all media in which any of the licensed items may be
recorded or stored and to all computer software and programs used for the
compilation or printout thereof. The use of such license or sublicense by the
Collateral Agent shall be exercised at the option of the Collateral Agent and
only upon the occurrence and during the continuation of an Event of Default;
provided that any license, sublicense or other transaction entered into by the
--------
Collateral Agent in accordance herewith shall be binding upon each applicable
Pledgor notwithstanding any subsequent cure of an Event of Default.

     6.5 Private Sales. Each Pledgor recognizes that, by reason of certain
         -------------
prohibitions contained in the Securities Act and applicable state securities
laws as in effect from time to time, the Collateral Agent may be compelled, with
respect to any sale of all or any part of the Pledged Interests conducted
without registration or qualification under the Securities Act and state
securities laws, to limit purchasers to any one or more Persons who will
represent and agree, among other things, to acquire such Pledged Interests for
their own account, for investment and not with a view to the distribution or
resale thereof. Each Pledgor acknowledges that any such private sales may be
made in such manner and under such circumstances as the Collateral Agent may
deem necessary or advisable in its discretion, including at prices and on terms
less favorable than those obtainable through a public sale without such
restrictions (including without limitation a public offering made pursuant to a
registration statement under the Securities Act), and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have

                                       28
<PAGE>

been made in a commercially reasonable manner and agrees that the Collateral
Agent shall have no obligation to conduct any public sales and no obligation to
delay the sale of any Pledged Interests for the period of time necessary to
permit its registration for public sale under the Securities Act and applicable
state securities laws, and shall not have any responsibility or liability as a
result of its election so not to conduct any such public sales or delay the sale
of any Pledged Interests, notwithstanding the possibility that a substantially
higher price might be realized if the sale were deferred until after such
registration. Each Pledgor hereby waives any claims against the Collateral Agent
or any other Secured Party arising by reason of the fact that the price at which
any Pledged Interests may have been sold at any private sale was less than the
price that might have been obtained at a public sale or was less than the
aggregate amount of the Secured Obligations, even if the Collateral Agent
accepts the first offer received and does not offer such Pledged Interests to
more than one offeree.

     6.6 The Pledgors Remain Liable. Notwithstanding anything herein to the
         --------------------------
contrary, (i) each Pledgor shall remain liable under all Contracts to which it
is a party included within the Collateral (including without limitation all
Ownership Agreements) to perform all of its obligations thereunder to the same
extent as if this Agreement had not been executed, (ii) the exercise by the
Collateral Agent of any of its rights or remedies hereunder shall not release
any Pledgor from any of its obligations under any of such Contracts, and (iii)
except as specifically provided for hereinbelow, neither the Collateral Agent
nor any Lender shall have any obligation or liability by reason of this
Agreement under any of such Contracts, nor shall the Collateral Agent or any
Lender be obligated to perform any of the obligations or duties of any Pledgor
thereunder or to take any action to collect or enforce any claim for payment
assigned hereunder. This Agreement shall not in any way be deemed to obligate
the Collateral Agent, any other Secured Party or any purchaser at a foreclosure
sale under this Agreement to assume any of a Pledgor's obligations, duties or
liabilities under any Ownership Agreement, including without limitation any
Pledgor's obligations, if any, to manage the business and affairs of the
applicable partnership, joint venture, limited liability company or other issuer
(collectively, the "Partner Obligations"), unless the Collateral Agent or such
                    -------------------
other Secured Party or purchaser otherwise agrees in writing to assume any or
all of such Partner Obligations. In the event of foreclosure by the Collateral
Agent hereunder, then except as provided in the preceding sentence, each
applicable Pledgor shall remain bound and obligated to perform its Partner
Obligations and neither the Collateral Agent nor any other Secured Party shall
be deemed to have assumed any Partner Obligations. In the event the Collateral
Agent, any other Secured Party or any purchaser at a foreclosure sale elects to
become a substitute partner or member in place of a Pledgor, the party making
such election shall adopt in writing such Ownership Agreement and agree to be
bound by the terms and provisions thereof; and subject to the execution of such
written agreement, each Pledgor hereby irrevocably consents in advance to the
admission of the Collateral Agent, any other Secured Party or any such purchaser
as a substitute partner or member to the extent of the Pledged Interests
acquired pursuant to such sale, and agrees to execute any documents or
instruments and take any other action as may be necessary or as may be requested
in connection therewith. The powers, rights and remedies conferred on the
Collateral Agent hereunder are solely to protect its interest and privilege in
such Contracts, as Collateral, and shall not impose any duty upon it to exercise
any such powers, rights or remedies.

     6.7 Waivers. Each Pledgor, to the greatest extent not prohibited by
         -------
applicable law, hereby (i) agrees that it will not invoke, claim or assert the
benefit of any rule of law or statute

                                       29
<PAGE>

now or hereafter in effect (including without limitation any right to prior
notice or judicial hearing in connection with the Collateral Agent's possession,
custody or disposition of any Collateral or any appraisal, valuation, stay,
extension, moratorium or redemption law), or take or omit to take any other
action, that would or could reasonably be expected to have the effect of
delaying, impeding or preventing the exercise of any rights and remedies in
respect of the Collateral, the absolute sale of any of the Collateral or the
possession thereof by any purchaser at any sale thereof, and to the extent
permitted by law waives the benefit of all such laws and further agrees that it
will not hinder, delay or impede the execution of any power granted hereunder to
the Collateral Agent, but that it will permit the execution of every such power
as though no such laws were in effect, (ii) waives all rights that it has or may
have under any rule of law or statute now existing or hereafter adopted to
require the Collateral Agent to marshal any Collateral or other assets in favor
of such Pledgor or any other party or against or in payment of any or all of the
Secured Obligations then due and payable, and (iii) to the extent permitted by
law waives all rights that it has or may have under any rule of law or statute
now existing or hereafter adopted to demand, presentment, protest, advertisement
or notice of any kind (except notices expressly provided for herein).

                                  ARTICLE VII

                              THE COLLATERAL AGENT

     7.1 The Collateral Agent; Standard of Care. The Collateral Agent will hold
         --------------------------------------
all items of the Collateral at any time received under this Agreement in
accordance with the provisions hereof. The obligations of the Collateral Agent
as holder of the Collateral and interests therein and with respect to the
disposition thereof, and otherwise under this Agreement and the Intercreditor
Agreement, are only those expressly set forth in this Agreement and the other
Intercreditor Agreement. The Collateral Agent shall act hereunder at the
direction, or with the consent, of the Required Secured Parties on the terms and
conditions set forth in the Intercreditor Agreement. The powers conferred on the
Collateral Agent hereunder are solely to protect its interest, on behalf of the
Secured Parties, in the Collateral, and shall not impose any duty upon it to
exercise any such powers. Except for treatment of the Collateral in its
possession in a manner substantially equivalent to that which the Collateral
Agent, in its individual capacity, accords its own property of a similar nature,
and the accounting for moneys actually received by it hereunder and the
Collateral Agent shall have no duty as to any Collateral or as to the taking of
any necessary steps to preserve rights against prior parties or any other rights
pertaining to the Collateral. Neither the Collateral Agent nor any other Secured
Party shall be liable to any Pledgor (i) for any loss or damage sustained by
such Pledgor, or (ii) for any loss, damage, depreciation or other diminution in
the value of any of the Collateral that may occur as a result of or in
connection with or that is in any way related to any exercise by the Collateral
Agent or any other Secured Party of any right or remedy under this Agreement,
any failure to demand, collect or realize upon any of the Collateral or any
delay in doing so, or any other act or failure to act on the part of the
Collateral Agent or any other Secured Party, except to the extent that the same
is caused by its own gross negligence or willful misconduct or fraud.

     7.2 Further Assurances; Attorney-in-Fact.
         ------------------------------------

     (a) Each Pledgor agrees that it will join with the Collateral Agent to
execute and, at its own expense, file and refile under the Uniform Commercial
Code such financing statements, continuation statements and other documents and
instruments in such offices as the Collateral Agent may deem necessary or
appropriate, and wherever required or permitted by law, in order to perfect and
preserve the Collateral Agent's security interest in the Collateral, and hereby
authorizes the Collateral Agent to file financing statements and amendments
thereto relating to all or any part of the Collateral in accordance with this
Agreement without the signature of such Pledgor where permitted by law, and
agrees to do such further acts and things (including without limitation making
any notice filings with state tax or revenue authorities required to be made by
account creditors in order to enforce any Accounts in such state) and to execute
and deliver to the Collateral Agent such additional conveyances, assignments,
agreements and instruments as the Collateral Agent may reasonably require or
deem advisable to perfect, establish, confirm and maintain the security interest
and Lien provided for herein, to carry out the purposes of this Agreement or to
further assure and confirm unto the Collateral Agent its rights, powers and
remedies hereunder.

     (b) Each Pledgor hereby irrevocably appoints the Collateral Agent its
lawful attorney-in-fact, with full authority in the place and stead of such
Pledgor and in the name of such Pledgor, the Collateral Agent or otherwise, and
with full power of substitution in the premises (which power of attorney, being
coupled with an interest, is irrevocable for so long as this Agreement shall be
in effect), from time to time in the Collateral Agent's discretion after the
occurrence and during the continuance of an Event of Default (except for the
actions described in clause (i)(A) below which may be taken by the Collateral
Agent without regard to whether an Event of Default has occurred) to take any
action and to execute any instruments that the Collateral Agent may deem
necessary or advisable to accomplish the purpose of this Agreement, including,
without limitation:

          (i) (A) to sign the name of such Pledgor on any financing statement,
     continuation statement, notice or other similar document that, in the
     Collateral Agent's opinion, should be made or filed in order to perfect or
     continue perfected the security interest granted under this Agreement and
     (B) to sign the name of such Pledgor on any title or ownership applications
     for filing with applicable state agencies to enable any motor vehicles now
     or hereafter owned by the Company to be retitled and the Collateral Agent
     listed as lienholder thereon;

          (ii) to ask, demand, collect, sue for, recover, compound, receive and
     give acquittance and receipts for moneys due and to become due under or in
     respect of any of the Collateral;

          (iii) to receive, endorse and collect any checks, drafts, instruments,
     chattel paper and other orders for the payment of money made payable to
     such Pledgor representing any interest, income, dividend, distribution or

          (iv) to obtain, maintain and adjust any property or casualty insurance
     required to be maintained by such Pledgor under Section 4.10 and direct the
     payment of proceeds thereof to the Collateral Agent;

          (v) to pay or discharge taxes, Liens or other encumbrances levied or
     placed on or threatened against the Collateral, the legality or validity
     thereof and the amounts necessary to discharge the same to be determined by
     the Collateral Agent in its sole discretion, any such payments made by the
     Collateral Agent to become Secured Obligations of the Pledgors to the
     Collateral Agent, due and payable immediately upon demand;

          (vi) to file any claims or take any action or institute any
     proceedings that the Collateral Agent may deem necessary or advisable for
     the collection of any of the Collateral or otherwise to enforce the rights
     of the Collateral Agent with respect to any of the Collateral; and

          (vii) to use, sell, assign, transfer, pledge, make any agreement with
     respect to or otherwise deal with any and all of the Collateral as fully
     and completely as though the Collateral Agent were the absolute owner of
     the Collateral for all purposes, and to do from time to time, at the
     Collateral Agent's option and the Pledgors' expense, all other acts and
     things deemed necessary by the Collateral Agent to protect, preserve or
     realize upon the Collateral and to more completely carry out the purposes
     of this Agreement.

     (c) If any Pledgor fails to perform any covenant or agreement contained in
this Agreement after written request to do so by the Collateral Agent, the
Collateral Agent may itself perform, or cause the performance of, such covenant
or agreement and may take any other action that it deems necessary and
appropriate for the maintenance and preservation of the Collateral or its
security interest therein, and the expenses so incurred in connection therewith
shall be payable by the Pledgors under Section 8.1.

     7.3 Incorporation of Credit Agreement Provisions. The provisions of
         --------------------------------------------
Sections 10.2, 10.3, 10.4, 10.6, 10.7, 10.8, and 10.9 of the Credit Agreement
(as amended from time to time) are incorporated herein and shall apply with
respect to the Collateral Agent in the same manner and with the same effect as
they apply or would apply with respect to the Agent (as defined in the Credit
Agreement) if it was acting as the Collateral Agent.

                                  ARTICLE VIII

                                  MISCELLANEOUS

     8.1 Indemnity and Expenses. The Pledgors agree jointly and severally:
         ----------------------

     (a) To indemnify and hold harmless the Collateral Agent, each other Secured
Party and each of their respective directors, officers, employees, agents and
affiliates from and against any and all claims, damages, demands, losses,
obligations, judgments and liabilities (including without limitation attorneys'
fees and expenses) in any way arising out of or in connection with this
Agreement and the transactions contemplated hereby, except to the extent the
same shall

                                       32
<PAGE>

arise as a result of the gross negligence or willful misconduct of the party
seeking to be indemnified; and

     (b) To pay and reimburse the Collateral Agent upon demand for all costs and
expenses (including without limitation attorneys' fees and expenses) that the
Collateral Agent may incur in connection with (i) the custody, use or
preservation of, or the sale of, collection from or other realization upon, any
of the Collateral, including the expenses of re-taking, holding, preparing for
sale or lease, selling or otherwise disposing of or realizing on the Collateral,
(ii) the exercise or enforcement of any rights or remedies granted hereunder
(including without limitation under Article VI), or otherwise available to it
(whether at law, in equity or otherwise), or (iii) the failure by any Pledgor to
perform or observe any of the provisions hereof. The provisions of this Section
8.1 shall survive the occurrence of the Termination Requirements (as hereinafter
defined).

     8.2 No Waiver. The rights and remedies of the Secured Parties expressly set
         ---------
forth in this Agreement, the other Credit Documents and the Operative Agreement
are cumulative and in addition to, and not exclusive of, all other rights and
remedies available at law, in equity or otherwise. No failure or delay on the
part of any Secured Party in exercising any right, power or privilege shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such right, power or privilege preclude any other or further exercise thereof or
the exercise of any other right, power or privilege or be construed to be a
waiver of any Default or Event of Default. To the extent permitted by law no
course of dealing between the Pledgors and the Secured Parties or their agents
or employees shall be effective to amend, modify or discharge any provision of
this Agreement, any other Credit Document or any Operative Agreement or to
constitute a waiver of any Default or Event of Default. No notice to or demand
upon any Pledgor in any case shall entitle such Pledgor or any other Pledgor to
any other or further notice or demand in similar or other circumstances or
constitute a waiver of the right of any Secured Party to exercise any right or
remedy or take any other or further action in any circumstances without notice
or demand.

     8.3 Pledgors' Obligations Absolute. Each Pledgor agrees that its
         ------------------------------
obligations hereunder, and the security interest granted to and all rights,
remedies and powers of the Collateral Agent hereunder, are irrevocable, absolute
and unconditional and shall not be discharged, limited or otherwise affected by
reason of any of the following, whether or not such Pledgor has knowledge
thereof:

          (i) any change in the time, manner or place of payment of, or in any
     other term of, any Secured Obligations, or any amendment, modification or
     supplement to, restatement of, or consent to any rescission or waiver of or
     departure from, any provisions of the Credit Agreement, any Subsidiary
     Guaranty, any other Credit Document, any Operative Agreement or any
     agreement or instrument delivered pursuant to any of the foregoing;

          (ii) the invalidity or unenforceability of any Secured Obligations or
     any provisions of the Credit Agreement, the Subsidiary Guaranty, any other
     Credit Document, any Operative Agreement or any agreement or instrument
     delivered pursuant to any of the foregoing;

                                       33
<PAGE>

          (iii) the addition or release of any other Pledgors hereunder or the
     taking, acceptance or release of any Secured Obligations of any other
     Person or additional Collateral or other security therefor;

          (iv) any sale, exchange, release, substitution, compromise,
     nonperfection or other action or inaction in respect of any Collateral or
     other direct or indirect security for any Secured Obligations, or any
     discharge, modification, settlement, compromise or other action or inaction
     in respect of any Secured Obligations of any other Person;

          (v) any agreement not to pursue or enforce or any failure to pursue or
     enforce (whether voluntarily or involuntarily as a result of operation of
     law, court order or otherwise) any right or remedy in respect of any
     Secured Obligations or any Collateral or other security therefor, or any
     failure to create, protect, perfect, secure, insure, continue or maintain
     any Liens in any such Collateral or other security;

          (vi) the exercise of any right or remedy available under the Credit
     Documents, any Operative Agreement, at law, in equity or otherwise in
     respect of any Collateral or other security for any Secured Obligations, in
     any order and by any manner thereby permitted, including without limitation
     foreclosure on any such Collateral or other security by any manner of sale
     thereby permitted, whether or not every aspect of such sale is commercially
     reasonable;

          (vii) any bankruptcy, reorganization, arrangement, liquidation,
     insolvency, dissolution, termination, reorganization or like change in the
     corporate structure or existence of the Borrower, any other Pledgor or any
     other Person directly or indirectly liable for any Secured Obligations;

          (viii) any manner of application of any payments by or amounts
     received or collected from any Person, by whomsoever paid and howsoever
     realized, whether in reduction of any Secured Obligations or any other
     obligations of the Borrower or any other Person directly or indirectly
     liable for any Secured Obligations, regardless of what Secured Obligations
     may remain unpaid after any such application; or

          (ix) any other circumstance that might otherwise constitute a legal or
     equitable discharge of, or a defense, set-off or counterclaim available to,
     the Borrower, any Pledgor or a surety or guarantor generally, other than
     the occurrence of all of the following: (x) the payment in full of the
     Secured Obligations (other than contingent liabilities that, by their
     nature, may accrue after principal of and interest on the Loans have been
     repaid in full), (y) the termination of the Commitments and the termination
     or expiration of all Letters of Credit under the Credit Agreement, and (z)
     the termination of, and settlement of all obligations of the Borrower
     under, each Hedge Agreement to which the Borrower and any Lender or
     Affiliate of any Lender are parties (the events in clauses (x), (y) and (z)
     above, collectively, the "Termination Requirements").
                               ------------------------

     8.4 Enforcement. By its acceptance of the benefits of this Agreement, each
         -----------
Secured Party agrees that this Agreement may be enforced only by the Collateral
Agent, acting upon the instructions or with the consent pursuant to the
Intercreditor Agreement, and that no Secured

                                       34
<PAGE>

Party shall have any right individually to enforce or seek to enforce this
Agreement or to realize upon any Collateral or other security given to secure
the payment and performance of the Secured Obligations.

     8.5 Amendments, Waivers, etc. No amendment, modification, waiver, discharge
         ------------------------
or termination of, or consent to any departure by any Pledgor from, any
provision of this Agreement, shall be effective unless in a writing signed by
the Collateral Agent and the Required Secured Parties or as otherwise may be
required under the provisions of the Intercreditor Agreement to concur in the
action then being taken, and then the same shall be effective only in the
specific instance and for the specific purpose for which given.

     8.6 Continuing Security Interest; Term; Successors and Assigns; Assignment;
         -----------------------------------------------------------------------
Termination and Release; Survival. This Agreement shall create a continuing
---------------------------------
security interest in the Collateral and shall secure the payment and performance
of all of the Secured Obligations as the same may arise and be outstanding at
any time and from time to time from and after the date hereof, and shall (i)
remain in full force and effect until the occurrence of the Termination
Requirements, (ii) be binding upon and enforceable against each Pledgor and its
successors and assigns (provided, however, that no Pledgor may sell, assign or
                        --------  -------
transfer any of its rights, interests, duties or obligations hereunder without
the prior written consent of the Lenders) and (iii) inure to the benefit of and
be enforceable (subject to the limitations of this Agreement) by each Secured
Party and its successors and assigns. Upon any sale or other disposition by any
Pledgor of any Collateral in a transaction expressly permitted hereunder or
under or pursuant to the Credit Agreement or any other applicable Credit
Document, the Operative Agreements, the Lien and security interest created by
this Agreement in and upon such Collateral shall be automatically released, and
upon the satisfaction of all of the Termination Requirements, this Agreement and
the Lien and security interest created hereby shall terminate; and in connection
with any such release or termination, the Collateral Agent, at the request and
expense of the applicable Pledgor, will execute and deliver to such Pledgor such
documents and instruments evidencing such release or termination as such Pledgor
may reasonably request and will assign, transfer and deliver to such Pledgor,
without recourse and without representation or warranty, such of the Collateral
as may then be in the possession of the Collateral Agent (or, in the case of any
partial release of Collateral, such of the Collateral so being released as may
be in its possession). All representations, warranties, covenants and agreements
herein shall survive the execution and delivery of this Agreement and any Pledge
Amendment or Pledgor Accession.

     8.7 Additional Pledgors. Each Pledgor recognizes that the provisions of the
         -------------------
Credit Agreement and the Operative Agreements require Persons that become
Subsidiaries of the Borrower, and that are not already parties hereto, to
execute and deliver a Pledgor Accession, whereupon each such Person shall become
a Pledgor hereunder with the same force and effect as if originally a Pledgor
hereunder on the date hereof, and agrees that its obligations hereunder shall
not be discharged, limited or otherwise affected by reason of the same, or by
reason of the Collateral Agent's actions in effecting the same or in releasing
any other Pledgor hereunder, in each case without the necessity of giving notice
to or obtaining the consent of such Pledgor or any other Pledgor.

                                       35

provisions set forth in the Credit Agreement, the Participation Agreement and
the Subsidiary Guaranty.

     8.9 Governing Law; Waiver of Jury Trial. This Agreement and the rights and
         -----------------------------------
obligations of the parties hereunder shall be governed by and construed and
enforced in accordance with the laws of the State of New York. Each of the
parties hereto irrevocably and unconditionally, to the fullest extent allowed by
applicable law, waives any right to trial by jury in any legal action or
proceeding arising under this Agreement or in any way connected with or related
or incidental to the dealings of the parties hereto with respect to this
Agreement or the transactions related hereto.

     8.10 Severability. To the extent any provision of this Agreement is
          ------------
prohibited by or invalid under the applicable law of any jurisdiction, such
provision shall be ineffective only to the extent of such prohibition or
invalidity and only in such jurisdiction, without prohibiting or invalidating
such provision in any other jurisdiction or the remaining provisions of this
Agreement in any jurisdiction.

     8.11 Construction. The headings of the various sections and subsections of
          ------------
this Agreement have been inserted for convenience only and shall not in any way
affect the meaning or construction of any of the provisions hereof. Unless the
context otherwise requires, words in the singular include the plural and words
in the plural include the singular.

     8.12 Counterparts. This Agreement may be executed in any number of
          ------------
counterparts and by different parties hereto on separate counterparts, each of
which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument.

     THIS SUBSIDIARY GUARANTY, dated as of the 1st day of February, 2002 (this
"Guaranty"), is made by each of the undersigned Subsidiaries of US ONCOLOGY,
 --------
INC., a Delaware corporation (the "Borrower"), and each other Subsidiary of the
                                   --------
Borrower that, after the date hereof, executes an instrument of accession hereto
substantially in the form of Exhibit A (a "Guarantor Accession"; the undersigned
                             ---------     -------------------
and such other Subsidiaries of the Borrower, collectively, the "Guarantors"), in
                                                                ----------
favor of the Guaranteed Parties (as hereinafter defined). Capitalized terms used
herein without definition shall have the meanings given to them in the Credit
Agreement referred to below.

                                    RECITALS

     A. The Borrower, certain banks and other financial institutions
(collectively, the "Lenders"), and First Union National Bank, as administrative
                    -------
agent for the Lenders (in such capacity, the "Agent"), are parties to a Credit
                                              -----
Agreement, dated as of February 1, 2002 (as amended, modified or supplemented
from time to time, the "Credit Agreement"), providing for the availability of
                        ---------------
certain credit facilities to the Borrower upon the terms and conditions set
forth therein.

     B. It is a condition to the extension of credit to the Borrower under the
Credit Agreement that each Guarantor shall have agreed, by executing and
delivering this Guaranty, to guarantee to the Guaranteed Parties the payment in
full of the Guaranteed Obligations (as hereinafter defined). The Guaranteed
Parties are relying on this Guaranty in their decision to extend credit to the
Borrower under the Credit Agreement, and would not enter into the Credit
Agreement without this Guaranty.

     C. The Borrower and the Guarantors are engaged in related businesses and
undertake certain activities and operations on an integrated basis. As part of
such integrated operations, the Borrower, among other things, will advance to
the Guarantors from time to time certain proceeds of the Loans made to the
Borrower by the Lenders under the Credit Agreement. Each Guarantor will
therefore obtain benefits as a result of the extension of credit to the Borrower
under the Credit Agreement, which benefits are hereby acknowledged, and,
accordingly, desires to execute and deliver this Guaranty.

                             STATEMENT OF AGREEMENT

     NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, to induce the Guaranteed Parties to enter into the Credit
Agreement and to induce the Lenders to extend credit to the Borrower thereunder,
each Guarantor hereby agrees as follows:

     with any Lender (or any Affiliate of any Lender to the extent contemplated
     by clause (b) below) in the capacity described in clause (b) below,

     defined), whether or not the claim for such interest is allowed in such
     proceeding), and all Obligations that, but for the operation of the
     automatic stay under Section 362(a) of the Bankruptcy Code, would become
     due, and (b) to each applicable Lender or Affiliate of any Lender in its
     capacity as a counterparty to any Hedge Agreement with the Borrower
     required or permitted under the Credit Agreement, all obligations of the
     Borrower under such Hedge Agreement (including any such Hedge Agreement
     with a party that subsequently ceases to be a Lender, which Hedge Agreement
     is entered into prior to the date such party ceases to be a Lender), in
     each case under (a) and (b) whether now existing or hereafter created or
     arising and whether direct or indirect, absolute or contingent, due or to
     become due (all liabilities and obligations described in this clause (i),

     the right to be indemnified hereunder for any such claims, losses, costs
     and expenses to the extent determined by a final and nonappealable judgment

     forth herein to have resulted from the gross negligence or willful
     misconduct of such indemnified party (all liabilities

     Obligations"; and the Other Obligations, together with the Guaranteed
     -----------
     Obligations, the "Total Obligations").
                       -----------------

     (b) Notwithstanding the provisions of subsection (a) above and
notwithstanding any other provisions contained herein or in any other Credit
Document:

          (i) no provision of this Guaranty shall require or permit the
     collection from any Guarantor of interest in excess of the maximum rate or
     amount that such Guarantor may be required or permitted to pay pursuant to
     applicable law; and

          (ii) the liability of each Guarantor under this Guaranty as of any
     date shall be limited to a maximum aggregate amount (the "Maximum
                                                               -------
     Guaranteed Amount") equal to the greatest amount that would not render such
     -----------------
     Guarantor's obligations under this Guaranty subject to avoidance, discharge
     or reduction as of such date as a fraudulent transfer or conveyance under
     applicable federal and state laws pertaining to bankruptcy, reorganization,
     arrangement, moratorium, readjustment of debts, dissolution, liquidation or
     other debtor relief, specifically including, without limitation, the
     Bankruptcy Code and any fraudulent transfer and fraudulent conveyance laws
     (collectively, "Insolvency Laws"), in each instance after giving effect to
                     ---------------
     all other liabilities of such Guarantor, contingent or otherwise, that are
     relevant under applicable Insolvency Laws (specifically excluding, however,
     any liabilities of such Guarantor in respect of intercompany indebtedness
     to the Borrower or any of its Affiliates to the extent that such
     indebtedness would be discharged in an amount equal to the amount paid by
     such Guarantor hereunder, and after giving effect as assets to the value
     (as determined under applicable Insolvency Laws) of any rights to
     subrogation, contribution, reimbursement, indemnity or similar rights of
     such Guarantor pursuant to (y) applicable law or (z) any agreement
     (including this Guaranty) providing for an equitable allocation among such
     Guarantor and other Affiliates of the Borrower of obligations arising under
     guaranties by such parties).

     (c) The Guarantors desire to allocate among themselves, in a fair and
equitable manner, their obligations arising under this Guaranty. Accordingly, in
the event any payment or distribution is made hereunder on any date by a
Guarantor (a "Funding Guarantor") that exceeds its Fair Share (as hereinafter
              -----------------
defined) as of such date, that Funding Guarantor shall be entitled to a
contribution from each of the other Guarantors in the amount of such other
Guarantor's Fair Share Shortfall (as hereinafter defined) as of such date, with
the result that all such contributions will cause each Guarantor's Aggregate
Payments (as hereinafter defined) to equal its Fair Share as of such date. "Fair
                                                                            ----
Share" means, with respect to a Guarantor as of any date of determination, an
-----
amount equal to (i) the ratio of (x) the Adjusted Maximum Guaranteed Amount (as
hereinafter defined) with respect to such Guarantor to (y) the aggregate of the
Adjusted Maximum Guaranteed Amounts with respect to all Guarantors, multiplied
by (ii) the aggregate amount paid or distributed on or before such date by all
Funding Guarantors hereunder in respect of the obligations guaranteed. "Fair
                                                                        ----
Share Shortfall" means, with respect to a Guarantor as of any date of
---------------
determination, the excess, if any, of the Fair Share of such Guarantor over the
Aggregate Payments of such Guarantor. "Adjusted Maximum Guaranteed Amount"
                                       ----------------------------------
means, with respect to a Guarantor as of any date of determination, the Maximum
Guaranteed Amount of such Guarantor, determined in accordance with the
provisions of subsection (b) above; provided
                                    --------

                                       3
<PAGE>

that, solely for purposes of calculating the "Adjusted Maximum Guaranteed
                                              ---------------------------
Amount" with respect to any Guarantor for purposes of this subsection (c), any
------
assets or liabilities arising by virtue of any rights to subrogation,
reimbursement or indemnity or any rights to or obligations of contribution
hereunder shall not be considered as assets or liabilities of such Guarantor.
"Aggregate Payments" means, with respect to a Guarantor as of any date of
 ------------------
determination, the aggregate amount of all payments and distributions made on or
before such date by such Guarantor in respect of this Guaranty (including,
without limitation, in respect of this subsection (c)). The amounts payable as
contributions hereunder shall be determined as of the date on which the related
payment or distribution is made by the applicable Funding Guarantor. Each
Funding Guarantor's right of contribution under this subsection (c) shall be
subject to the provisions of Section 4. The allocation among Guarantors of their
obligations as set forth in this subsection (c) shall not be construed in any
way to limit the liability of any Guarantor hereunder to the Guaranteed Parties.

     (d) The guaranty of each Guarantor set forth in this Section is a guaranty
of payment as a primary obligor, and not a guaranty of collection. Each
Guarantor hereby acknowledges and agrees that the Guaranteed Obligations, at any
time and from time to time, may exceed the Maximum Guaranteed Amount of such
Guarantor and may exceed the aggregate of the Maximum Guaranteed Amounts of all
Guarantors, in each case without discharging, limiting or otherwise affecting
the obligations of any Guarantor hereunder, except as specifically provided
otherwise in this Section, or the rights, powers and remedies of any Guaranteed
Party hereunder or under any other Credit Document.

     2. Guaranty Absolute. Each Guarantor agrees that its obligations hereunder
        -----------------
are irrevocable, absolute and unconditional, are independent of the Guaranteed
Obligations and any Collateral or other security therefor or other guaranty or
liability in respect thereof, whether given by such Guarantor or any other
Person, and shall not be discharged, limited or otherwise affected by reason of
any of the following, whether or not such Guarantor has notice or knowledge
thereof:

          (i) any change in the time, manner or place of payment of, or in any
     other term of, any Guaranteed Obligations or any guaranty or other
     liability in respect thereof, or any amendment, modification or supplement
     to, restatement of, or consent to any rescission or waiver of or departure
     from, any provisions of the Credit Agreement, any other Credit Document or
     any agreement or instrument delivered pursuant to any of the foregoing;

          (ii) the invalidity or unenforceability of any Guaranteed Obligations,
     any guaranty or other liability in respect thereof or any provisions of the
     Credit Agreement, any other Credit Document or any agreement or instrument
     delivered pursuant to any of the foregoing;

          (iii) the addition or release of Guarantors hereunder or the taking,

                                           ------------------------
     3. Certain Waivers. Each Guarantor hereby knowingly, voluntarily and
        ---------------
expressly waives:

          (i) presentment, demand for payment, demand for performance, protest
     and notice of any other kind, including, without limitation, notice of

<PAGE>

     referred to in Section 2 and of any rights to consent thereto;

          (ii) any right to require the Guaranteed Parties or any of them, as a
     condition of payment or performance by such Guarantor hereunder, to proceed

     other Guarantor or any other Person directly or indirectly liable for any
     Guaranteed Obligations, or to pursue any other remedy or enforce any other
     right; and any other defense based on an election of remedies with respect
     to any Collateral or other security for any Guaranteed Obligations of for
     any guaranty or other liability in respect thereof, notwithstanding that
     any such election (including any failure to pursue or enforce any rights or
     remedies) may impair or extinguish any right of indemnification,
     contribution, reimbursement or subrogation or other right or remedy of any
     Guarantor against the Borrower, any other Guarantor or any other Person
     directly or indirectly liable for any Guaranteed Obligations or any such
     Collateral or other security; and, without limiting the generality of the
     foregoing, each Guarantor hereby specifically waives the benefits of
     Sections 26-7 through 26-9, inclusive, of the General Statutes of North
     Carolina, as amended from time to time, and any similar statute or law of
     any other jurisdiction, as the same may be amended from time to time;

          (iii) any right or defense based on or arising by reason of any right
     or defense (other than satisfaction of the Termination Requirements) of the
     Borrower or any other Person, including, without limitation, any defense
     based on or arising from a lack of authority or other disability of the
     Borrower or any other Person, the invalidity or unenforceability of any
     Guaranteed Obligations, any Collateral or other security therefor or any
     Credit Document or other agreement or instrument delivered pursuant
     thereto, or the cessation of the liability of the Borrower for any reason
     other than the satisfaction of the Termination Requirements;

          (iv) any defense based on any Guaranteed Party's acts or omissions in
     the administration of the Guaranteed Obligations, any guaranty or other
     liability in respect thereof or any Collateral or other security for any of
     the foregoing, and promptness, diligence or any requirement that any
     Guaranteed Party create, protect, perfect, secure, insure, continue or
     maintain any Liens in any such Collateral or other security;

          (v) any right to assert against any Guaranteed Party, as a defense,
     counterclaim, crossclaim or set-off, any defense, counterclaim, claim,
     right of recoupment or set-off that it may at any time have against any
     Guaranteed Party (including, without limitation, failure of consideration,
     statute of limitations, payment, accord and satisfaction and usury), other
     than compulsory counterclaims; and

          (vi) any defense based on or afforded by any applicable law that

     any other way conflict with the terms of this Guaranty.

                                       6

     4. No Subrogation. Each Guarantor hereby agrees that, until satisfaction of
        --------------
the Termination Requirements, it will not exercise or seek to exercise any claim
or right that it may have against the Borrower or any other Guarantor at any
time as a result of any payment made under or in connection with this Guaranty
or the performance or enforcement hereof, including any right of subrogation to
the rights of any of the Guaranteed Parties against the Borrower or any other
Guarantor, any right of indemnity, contribution or reimbursement against the
Borrower or any other Guarantor (including rights of contribution as set forth
in Section 1(c)), any right to enforce any remedies of any Guaranteed Party
against the Borrower or any other Guarantor, or any benefit of, or any right to
participate in, any Collateral or other security held by any Guaranteed Party to
secure payment of the Guaranteed Obligations, in each case whether such claims
or rights arise by contract, statute (including without limitation the
Bankruptcy Code), common law or otherwise. Each Guarantor further agrees that
all indebtedness and other obligations, whether now or hereafter existing, of
the Borrower or any other Subsidiary of the Borrower to such Guarantor,
including, without limitation, any such indebtedness in any proceeding under the
Bankruptcy Code and any intercompany receivables, together with any interest
thereon, shall be, and hereby are, subordinated and made junior in right of
payment to the Total Obligations. Each Guarantor further agrees that if any
amount shall be paid to or any distribution received by any Guarantor (i) on
account of any such indebtedness at any time after the occurrence and during the
continuance of an Event of Default, or (ii) on account of any such rights of
subrogation, indemnity, contribution or reimbursement at any time prior to the
satisfaction of the Termination Requirements, such amount or distribution shall
be deemed to have been received and to be held in trust for the benefit of the
Guaranteed Parties, and shall forthwith be delivered to the Agent in the form
received (with any necessary endorsements in the case of written instruments),
to be applied against the Guaranteed Obligations, whether or not matured, in
accordance with the terms of the applicable Credit Documents and without in any
way discharging, limiting or otherwise affecting the liability of such Guarantor
under any other provision of this Guaranty. Additionally, in the event the
Borrower or any Subsidiary of the Borrower becomes a "debtor" within the meaning
of the Bankruptcy Code, the Agent shall be entitled, at its option, on behalf of
the Guaranteed Parties and as attorney-in-fact for each Guarantor, and is hereby
authorized and appointed by each Guarantor, to file proofs of claim on behalf of
each relevant Guarantor and vote the rights of each such Guarantor in any plan
of reorganization, and to demand, sue for, collect and receive every payment and
distribution on any indebtedness of the Borrower or such Subsidiary to any
Guarantor in any such proceeding, each Guarantor hereby assigning to the Agent
all of its rights in respect of any such claim, including the right to receive
payments and distributions in respect thereof.

     5. Representations and Warranties. Each Guarantor hereby represents and
        ------------------------------
warrants to the Guaranteed Parties as follows:

     (a) Such Guarantor is a corporation, partnership or other entity duly
organized, validly existing and, to the extent applicable, in good standing
under the laws of the jurisdiction of its incorporation or organization and has
the full power and authority to execute, deliver and perform this Guaranty and
the other Credit Documents to which it is or will be a party, to own and hold
its property and to engage in its business as presently conducted.

     (b) Such Guarantor has taken all necessary corporate or partnership action
to execute, deliver and perform this Guaranty and each of the other Credit
Documents to which it is or will

<PAGE>

be a party, and has, or on any later date of execution and delivery will have,
validly executed and delivered each of the Credit Documents to which it is or
will be a party. This Guaranty constitutes, and each of such other Credit
Documents upon execution and delivery will constitute, the legal, valid and
binding obligation of such Guarantor, enforceable against such Guarantor in
accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting creditors' rights generally or by general equitable principles.

     (c) The execution, delivery and performance by such Guarantor of this
Guaranty and the other Credit Documents to which it is a party, and compliance
by it with the terms hereof and thereof, do not and will not (i) violate any
provision of its articles or certificate of incorporation or bylaws, (ii)
contravene any Requirement of Law applicable to it, (iii) conflict with, result
in a breach of or constitute (with notice, lapse of time or both) a default
under any indenture, loan agreement, mortgage, deed of trust, lease or other
agreement or instrument to which it is a party, by which it or any of its
properties is bound or to which it is subject, or (iv) result in or require the
creation or imposition of any Lien upon any of its properties, other than Liens
created pursuant to the Credit Documents.

     (d) No consent, approval, authorization or other action by, notice to, or
registration or filing with, any Governmental Authority is or will be required
as a condition to or otherwise in connection with the due execution, delivery
and performance by such Guarantor of this Guaranty and the other Credit
Documents to which it is a party or the legality, validity or enforceability
hereof or thereof, other than (i) filings of Mortgages, Uniform Commercial Code
financing statements and other instruments and actions necessary to perfect the
Liens created by the Security Documents, (ii) consents, authorizations and
filings that have been made or obtained and that are in full force and effect,
which consents, authorizations and filings are listed on Schedule 5.4, and (iii)
consents and filings the failure to obtain or make which would not, individually
or in the aggregate, have a Material Adverse Effect..

     (e) Except as may be disclosed in Schedule 5.5 to the Credit Agreement,
there are no actions, investigations, suits or proceedings pending or, to the
knowledge of such Guarantor, threatened, at law, in equity or in arbitration,
before any court, other Governmental Authority or other Person, (i) against or
affecting such Guarantor or any of its properties that would, if adversely
determined, be reasonably likely to have a Material Adverse Effect or (ii) with
respect to this Guaranty or any of the other Credit Documents to which such
Guarantor is a party.

     (f) Such Guarantor has been provided with a true and complete copy of the
executed Credit Agreement, as in effect as of the date it became a party hereto,
and its principal officers are familiar with the contents thereof, particularly
insofar as the contents thereof relate or apply to such Guarantor.

     6. Financial Condition of Borrower. Each Guarantor represents that it has
        -------------------------------
knowledge of the Borrower's financial condition and affairs and that it has
adequate means to obtain from the Borrower on an ongoing basis information
relating thereto and to the Borrower's ability to pay and perform the Guaranteed
Obligations, and agrees to assume the responsibility for keeping, and to keep,
so informed for so long as this Guaranty is in effect with respect to such
Guarantor. Each Guarantor agrees that the Guaranteed Parties shall have no
obligation to investigate the

                                       8
<PAGE>

financial condition or affairs of the Borrower for the benefit of any Guarantor
nor to advise any Guarantor of any fact respecting, or any change in, the
financial condition or affairs of the Borrower that might become known to any
Guaranteed Party at any time, whether or not such Guaranteed Party knows or
believes or has reason to know or believe that any such fact or change is
unknown to any Guarantor, or might (or does) materially increase the risk of any
Guarantor as guarantor, or might (or would) affect the willingness of any
Guarantor to continue as a guarantor of the Guaranteed Obligations.

     7. Payments; Application; Set-Off.
        ------------------------------

     (a) Each Guarantor agrees that, upon the failure of the Borrower to pay any
Guaranteed Obligations when and as the same shall become due (whether at the
stated maturity, by acceleration or otherwise), and without limitation of any
other right or remedy that any Guaranteed Party may have at law, in equity or
otherwise against such Guarantor, such Guarantor will, subject to the provisions
of Section 1(b), forthwith pay or cause to be paid to the Agent, for the benefit
of the Guaranteed Parties, an amount equal to the amount of the Guaranteed
Obligations then due and owing as aforesaid.

     (b) All payments made by each Guarantor hereunder will be made in Dollars
to the Agent, without set-off, counterclaim or other defense and, in accordance
with Section 2.17 of the Credit Agreement, free and clear of and without
deduction for any Taxes, each Guarantor hereby agreeing to comply with and be
bound by the provisions of Section 2.17 of the Credit Agreement in respect of
all payments made by it hereunder and the provisions of which Section are hereby
incorporated into and made a part of this Guaranty by this reference as if set
forth herein at length.

     (c) All payments made hereunder shall be applied upon receipt as follows:

          (i) first, to the payment of all Other Obligations owing to the Agent;

          (ii) second, after payment in full of the amounts specified in clause
     (i) above, to the ratable payment of all other Total Obligations owing to
     the Guaranteed Parties; and

          (iii) third, after payment in full of the amounts specified in clauses
     (i) and (ii) above, and following the termination of this Guaranty, to the
     Guarantors or any other Person lawfully entitled to receive such surplus.

     (d) For purposes of applying amounts in accordance with this Section, the
Agent shall be entitled to rely upon any Guaranteed Party that has entered into
a Hedge Agreement with the Borrower for a determination (which such Guaranteed
Party agrees to provide or cause to be provided upon request of the Agent) of
the outstanding Guaranteed Obligations owed to such Guaranteed Party under any
such Hedge Agreement. Unless it has actual knowledge (including by way of
written notice from any such Guaranteed Party) to the contrary, the Agent, in
acting hereunder, shall be entitled to assume that no Hedge Agreements or
Guaranteed Obligations in respect thereof are in existence between any
Guaranteed Party and the Borrower. If any Lender that is a party to a Hedge
Agreement with the Borrower (the obligations of the Borrower under which are
Guaranteed Obligations) ceases to be a Lender, such former Lender shall
nevertheless

                                       9
<PAGE>

continue to be a Guaranteed Party hereunder with respect to the Guaranteed
Obligations under such Hedge Agreement.

     (e) The Guarantors shall remain jointly and severally liable to the extent
of any deficiency between the amount of all payments made hereunder and the
aggregate amount of the sums referred to in clauses (i) and (ii) of subsection
(c) above.

     (f) In addition to all other rights and remedies available under the Credit
Documents or applicable law or otherwise, upon and at any time after the
occurrence and during the continuance of any Event of Default, each Guaranteed
Party may, and is hereby authorized by each Guarantor, at any such time and from
time to time, to the fullest extent permitted by applicable law, without
presentment, demand, protest or other notice of any kind, all of which are
hereby knowingly and expressly waived by each Guarantor, to set off and to apply
any and all deposits (general or special, time or demand, provisional or final)
and any other property at any time held (including at any branches or agencies,
wherever located), and any other indebtedness at any time owing, by such
Guaranteed Party to or for the credit or the account of such Guarantor against
any or all of the obligations of such Guarantor to such Guaranteed Party
hereunder now or hereafter existing, whether or not such obligations may be
contingent or unmatured, each Guarantor hereby granting to each Guaranteed Party
a continuing security interest in and Lien upon all such deposits and other
property as security for such obligations. Each Guaranteed Party agrees to
notify any affected Guarantor promptly after any such set-off and application;
provided, however, that the failure to give such notice shall not affect the
--------  -------
validity of such set-off and application. NOTWITHSTANDING THE FOREGOING, NO
GUARANTEED PARTY SHALL EXERCISE, OR ATTEMPT TO EXERCISE, ANY RIGHT OF SETOFF,
BANKER'S LIEN OR THE LIKE, AGAINST ANY DEPOSIT ACCOUNT OR PROPERTY OF ANY
GUARANTOR HELD BY SUCH GUARANTEED PARTY, WITHOUT THE PRIOR WRITTEN CONSENT OF
THE REQUIRED LENDERS, AND ANY GUARANTEED PARTY VIOLATING THIS PROVISION SHALL
INDEMNIFY THE OTHER GUARANTEED PARTIES FROM ANY AND ALL COSTS, EXPENSES,
LIABILITIES AND DAMAGES RESULTING THEREFROM. The contractual restriction on the
exercise of setoff rights provided in the foregoing sentence is solely for the
benefit of the Guaranteed Parties and may not be enforced by the Borrower or any
Guarantor.

     8. No Waiver. The rights and remedies of the Guaranteed Parties expressly
        ---------
set forth in this Guaranty and the other Credit Documents are cumulative and in
addition to, and not exclusive of, all other rights and remedies available at
law, in equity or otherwise. No failure or delay on the part of any Guaranteed
Party in exercising any right, power or privilege shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right, power or
privilege preclude any other or further exercise thereof or the exercise of any
other right, power or privilege or be construed to be a waiver of any Default or
Event of Default. No course of dealing between any of the Guarantors and the
Guaranteed Parties or their agents or employees shall be effective to amend,
modify or discharge any provision of this Guaranty or any other Credit Document
or to constitute a waiver of any Default or Event of Default. No notice to or
demand upon any Guarantor in any case shall entitle such Guarantor or any other
Guarantor to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the right of any Guaranteed Party to
exercise any right or remedy or take any other or further action in any
circumstances without notice or demand.

                                       10
<PAGE>

     9. Enforcement. The Guaranteed Parties agree that, except as provided in
        -----------
Section 7(f), this Guaranty may be enforced only by the Agent, acting upon the
instructions or with the consent of the Required Lenders as provided for in the
Credit Agreement, and that no Guaranteed Party shall have any right individually
to enforce or seek to enforce this Guaranty or to realize upon any Collateral or
other security given to secure the payment and performance of the Guarantors'
obligations hereunder. The obligations of each Guarantor hereunder are
independent of the Guaranteed Obligations, and a separate action or actions may
be brought against each Guarantor whether or not action is brought against the
Borrower or any other Guarantor and whether or not the Borrower or any other
Guarantor is joined in any such action. Each Guarantor agrees that to the extent
all or part of any payment of the Guaranteed Obligations made by any Person is
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required to be repaid by or on behalf of any Guaranteed Party to a trustee,
receiver or any other party under any Insolvency Laws (the amount of any such
payment, a "Reclaimed Amount"), then, to the extent of such Reclaimed Amount,
            ----------------
this Guaranty shall continue in full force and effect or be revived and
reinstated, as the case may be, as to the Guaranteed Obligations intended to be
satisfied as if such payment had not been received; and each Guarantor
acknowledges that the term "Guaranteed Obligations" includes all Reclaimed
                            ----------------------
Amounts that may arise from time to time.

     10. Amendments, Waivers, etc. No amendment, modification, waiver, discharge
         ------------------------
or termination of, or consent to any departure by any Guarantor from, any
provision of this Guaranty, shall be effective unless in a writing signed by the
Agent and such of the Lenders as may be required under the provisions of the
Credit Agreement to concur in the action then being taken, and then the same
shall be effective only in the specific instance and for the specific purpose
for which given.

     11. Addition, Release of Guarantors. Each Guarantor recognizes that the
         -------------------------------
provisions of the Credit Agreement require Persons that become Subsidiaries of
the Borrower and that are not already parties hereto to become Guarantors
hereunder by executing a Guarantor Accession, and agrees that its obligations
hereunder shall not be discharged, limited or otherwise affected by reason of
the same, or by reason of the Agent's actions in effecting the same or in
releasing any Guarantor hereunder, in each case without the necessity of giving
notice to or obtaining the consent of any other Guarantor.

     12. Continuing Guaranty; Term; Successors and Assigns; Assignment;
         --------------------------------------------------------------
Survival. This Guaranty is a continuing guaranty and covers all of the
-------
Guaranteed Obligations as the same may arise and be outstanding at any time and
from time to time from and after the date hereof, and shall (i) remain in full
force and effect until satisfaction of all of the Termination Requirements
(provided that the provisions of clause (ii) of Section 1(a) shall survive any
 --------
termination of this Guaranty), (ii) be binding upon and enforceable against each
Guarantor and its successors and assigns (provided, however, that no Guarantor
                                          --------  -------
may sell, assign or transfer any of its rights, interests, duties or obligations
hereunder without the prior written consent of the Lenders) and (iii) inure to
the benefit of and be enforceable by each Guaranteed Party and its successors
and assigns. Without limiting the generality of clause (iii) above, any
Guaranteed Party may, in accordance with the provisions of the Credit Agreement,
assign all or a portion of the Guaranteed Obligations held by it (including by
the sale of participations), whereupon each Person that becomes the holder of
any such Guaranteed Obligations shall (except as may be otherwise

                                       11
<PAGE>

agreed between such Guaranteed Party and such Person) have and may exercise all
of the rights and benefits in respect thereof granted to such Guaranteed Party
under this Guaranty or otherwise. Each Guarantor hereby irrevocably waives
notice of and consents in advance to the assignment as provided above from time
to time by any Guaranteed Party of all or any portion of the Guaranteed
Obligations held by it and of the corresponding rights and interests of such
Guaranteed Party hereunder in connection therewith. All representations,
warranties, covenants and agreements herein shall survive the execution and
delivery of this Guaranty and any Guarantor Accession.

     THIS FINANCIAL CONDITION CERTIFICATE is delivered pursuant to Section

terms used herein without definition shall have the meanings given to such terms
in the Credit Agreement.

     The undersigned hereby certifies for and on behalf of the Borrower as
follows:

     1. Capacity. The undersigned is, and at all pertinent times mentioned
        --------
herein has been, the duly qualified and acting [Vice President-Finance] of the
Borrower, and in such capacity has responsibility for the management of the
Borrower's financial affairs and for the preparation of the Borrower's financial
statements. The undersigned has, together with other officers of the Borrower,
acted on behalf of the Borrower in connection with the negotiation and
consummation of the Credit Agreement and the consummation of the transactions
contemplated thereby.

     2. Procedures. For purposes of this Certificate, the undersigned has, as of
        ----------
or prior to the date hereof, undertaken the following activities in connection
herewith:

     2.1  The undersigned has carefully reviewed the following:

          (a) the contents of this Certificate;

          (b) the Credit Agreement (including the exhibits and schedules
     thereto);

          (c) the amendments to the End Loaded Lease Facility effected on the
     date hereof;

          (d) the audited consolidated and unaudited consolidating balance
     sheets of the Borrower and its Subsidiaries as of December 31, 2000, 1999
     and 1998, and the related consolidated and consolidating statements of
     income, stockholders' equity and cash flows of the Borrower and its
     Subsidiaries for the fiscal years then ended, each certified by
     PricewaterhouseCoopers, LLC; and

          (e) the unaudited consolidated and consolidating balance sheets of the
     Borrower and its Subsidiaries as of December 31, 2001, and the related
     consolidated and consolidating statements of income, stockholders' equity
     and cash flows of the Borrower and its Subsidiaries for the twelve-month
     period then ended.
<PAGE>

     2.2 Additionally, in preparation for the consummation of the transactions
contemplated by the Credit Agreement and the End Loaded Loan Facility (the
"Transactions") the undersigned has prepared or supervised the preparation of
 ------------
and has reviewed an unaudited consolidated balance sheet of the Borrower as of
December 31, 2001, a copy of which balance sheet is attached hereto as Annex A.
                                                                       -------
The undersigned also has prepared or supervised the preparation of and has
reviewed projected balance sheets and statements of income and cash flows of the
Borrower (i) on a quarterly basis for the eight-quarter period beginning with
the quarter ending December 31, 2001 and (ii) on an annual basis from the fiscal
year ending December 31, 2002 through the fiscal year ending December 31, 2007,
in each case giving effect to the issuance of the Subordinated Notes, the
initial extensions of credit made under the Credit Agreement, the payment of
transaction fees and expenses related to the foregoing, and the Restructuring
(the "Projections").
      -----------

     2.3 The undersigned, together with the other officers and personnel of the
Borrower who were involved in the preparation of the Projections, have relied on
historical financial and other information and upon information with respect to
sales, costs and other data obtained in discussions with executive officers of
the Borrower and other officers and supervisory personnel directly responsible
for the various operations involved. The undersigned has reexamined the
Projections as of the date hereof, and has considered the continuing
reasonableness of the assumptions set forth therein and the effect thereon of
any changes since the date of preparation thereof on the financial condition set
forth and the results projected therein.

     2.4 The undersigned has made inquiries of certain other officers and
personnel of the Borrower with responsibility for financial and accounting
matters regarding (i) whether the unaudited financial statements described in
paragraph 2.1(d) above are in conformity with GAAP applied on a basis consistent
with that of the audited financial statements described in paragraph 2.1(c)
above (subject to the absence of footnotes required by GAAP and subject to
normal year-end adjustments), and whether notes omitted from such unaudited
financial statements would have disclosed any new information that would be
necessary to make the statements contained therein not misleading, and (ii)
whether such persons were aware of any events or conditions that, as of the date
hereof, would cause the statements made in paragraph 3 below to be untrue.

     2.5 With respect to any contingent liabilities of the Borrower on a pro
forma basis after giving effect to the Transactions, the undersigned:

          (a) has inquired of certain officers and other personnel of the
     Borrower who have responsibility for the legal, financial and accounting
     affairs of the Borrower, as to the existence and estimated amounts of all
     contingent liabilities known to them;

          (b) has confirmed with senior accounting officers of the Borrower
     that, to the best of such officers' knowledge, (i) all appropriate items
     have been included in contingent liabilities made known to the undersigned
     in the course of the inquiry of the undersigned in connection herewith, and
     (ii) the amounts relating thereto were the maximum estimated amounts of
     liability reasonably likely to result therefrom as of the date hereof, and
<PAGE>

          (c) confirms that, to the best of his knowledge, all material
     contingent liabilities that may arise from any pending litigation, asserted
     claims and assessments, guarantees, uninsured risks, and other relevant
     contingencies and circumstances have been considered in making the
     certification set forth herein, and with respect to each such contingent
     liability the maximum estimated amount of liability with respect thereto
     was used in making such certification.

     2.6 The undersigned has conferred with counsel to the Borrower for the
purpose of discussing the meaning of the contents of this Certificate.

     3. Certifications. Based on the foregoing, the undersigned hereby certifies
        --------------
as follows:

     3.1 The Projections give effect to the consummation of the initial
extensions of credit made under the Credit Agreement, the extensions of credit
outstanding under the End Loaded Lease Facility, the payment of transaction fees
and expenses incident to the foregoing, and the consummation of all of the other
Transactions. In the opinion of the undersigned, the assumptions used in the
preparation of the Projections were fair, complete and reasonable when made and
continue to be fair, complete and reasonable as of the date hereof. The
Projections have been prepared in good faith by the executive and financial
personnel of the Borrower, are complete and represent a reasonable estimate of
the future performance and financial condition of the Borrower and its
Subsidiaries, subject to the uncertainties and approximations inherent in any
projections.

     3.2 After giving effect to the Transactions, all material accounts and
other liabilities of the Borrower and its Subsidiaries are current and not past
due.

     3.3 Neither the Borrower nor any Subsidiary is insolvent now, and the
incurrence by the Borrower and each Subsidiary of its liabilities and
obligations pursuant to the Credit Agreement and the other Loan Documents and
the consummation of the other Transactions will not render it insolvent. The
undersigned understands that, in this context, (i) "insolvent" means that the
present fair saleable value of assets is less than the amount that will be
required to be paid on or in respect of the existing debts as such debts mature,
(ii) "fair value" of assets means the aggregate amount that could be realized
within a reasonable time, either through collection or sale of such assets at
the regular market value as an ongoing business, conceiving of the latter as the
amount that could be obtained for the property in question within such period by
a capable and diligent seller from an interested buyer who is willing to
purchase under ordinary selling conditions, and (iii) "debts" includes any legal
liability, whether matured or unmatured, liquidated or unliquidated, absolute,
fixed or contingent, including any guaranty or other contingent obligation. A
valuation of the Borrower and its Subsidiaries, on the basis thereof and with
reasonable allowance for error, would reflect the net worth of the Borrower and
its Subsidiaries (on a consolidated basis) in the aggregate (excess of fair
value of assets over liabilities) as not less than [$             ].
                                                     -------------

     3.4 The undersigned reasonably believes that, by the incurrence of its
liabilities and obligations pursuant to the Credit Agreement and the other Loan
Documents and the consummation of the other Transactions, neither the Borrower
nor any Subsidiary will incur debts beyond its ability to pay as they mature
(taking into account the timing and amounts of cash to be payable on or in
respect of its debts). The foregoing conclusion is based in part on the
<PAGE>

Projections, which demonstrate that the cash flow of the Borrower and its
Subsidiaries, after taking into account all anticipated uses of cash of each
such Person, will at all times be sufficient to pay all amounts on or in respect
of Indebtedness of each such Person when such amounts are required to be paid
(including without limitation scheduled payments pursuant to the Credit
Agreement). The undersigned has concluded that the realization of current assets
in the ordinary course of business should be sufficient to pay recurring current
debt, short-term debt and long-term debt as such debts mature, that the cash
flow (including earnings plus non-cash charges to earnings) should be sufficient
to provide cash necessary to repay loans made under the Credit Agreement and
other long-term indebtedness as such debt matures, and that the Borrower should
have sufficient availability under the Credit Agreement to satisfy its working
capital and short-term liquidity requirements.

     3.5 After giving effect to the consummation of the Transactions, the assets
of the Borrower and each Subsidiary do not constitute "unreasonably small
capital" (within the meaning of Section 548(a) of the Bankruptcy Code, 11 U.S.C.
Section 548(a)) for such Person to carry on its business as now conducted and as
proposed to be conducted, taking into account the particular capital
requirements of the business conducted and to be conducted by it and the
availability of capital in respect thereof (with reference to, without
limitation, the Projections and the Borrower's available credit capacity).

     3.6 Neither the Borrower nor any Subsidiary has executed the Credit
Agreement or any other documents mentioned therein, or made any transfer or
incurred any obligations thereunder, with intent to hinder, delay or defraud
either present or future creditors of such Person.

     3.7 The statements made herein by the undersigned are based upon the
personal knowledge of the undersigned, or upon reports and other information
given to the undersigned by supervisory personnel of the Borrower having
responsibility for the reports and information given, and who in the opinion of
the undersigned are reliable and entitled to be relied upon. The statements made
herein are made in good faith and, to the best of the knowledge and belief of
the undersigned, and are reasonable in all material respects.

     3.8 The undersigned understands that the Lenders have performed their own
review and analysis of the financial condition of the Borrower, but that the
Lenders are relying on the foregoing statements in connection with the extension
of credit to the Borrower pursuant to the Credit Agreement.

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

     Encumbrances to the extent of those rights.

          (d) This Mortgage, when duly recorded in the appropriate public
     records and when financing statements are duly filed in the appropriate
     public records, will create a valid, perfected and enforceable lien upon

     Property, the Grantor will pay all sums, including reasonable attorneys'
     fees and disbursements, actually incurred (not as imposed by statute) by
     the Trustee or the Beneficiary related to the exercise of any remedy or
     right of the Trustee or the Beneficiary pursuant hereto or for the expense
     of any such action or proceeding together with all statutory or other
     costs, disbursements and allowances, interest thereon from the date of
     demand for payment thereof at the rate specified in Section 2.8(b) of the
     Credit Agreement (the "Default Interest Rate"), and such sums and the
                            ---------------------
     interest thereon shall, to the extent permissible by law, be a lien on the
     Trust Property prior to any right, title to, interest in or claim upon the
     Trust Property attaching or accruing subsequent to the recording of this
     Mortgage and shall be secured by this Mortgage to the extent permitted by
     applicable law.

          (c) Any payment of amounts due under this Mortgage not made on or
     before the due date for such payments shall accrue interest daily without
     notice from the due date until paid at the Default Interest Rate, and such
     interest at the Default Interest Rate shall be immediately due upon demand
     by the Trustee or the Beneficiary.

          (a) Except as may be permitted by Section 6.5 of the Credit Agreement
     or Section 8.3(o) of the Participation Agreement, the Grantor will pay and
     discharge from time to time prior to the time when the same shall become

     the occupancy, use or possession thereof.

          (b) In the event of the passage of any state, federal, municipal or
     other governmental law, order, rule or regulation subsequent to the date
     hereof (i) deducting from the value of real property for the purpose of
     taxation any lien or encumbrance thereon or in any manner changing or
     modifying the laws now in force governing the taxation of this Mortgage or
     debts secured by mortgages or deeds of trust (other than laws governing
     income, franchise and similar taxes generally) or the manner of collecting
     taxes thereon and (ii) imposing a tax to be paid by the Beneficiary or the
     Trustee, either

                                       8
<PAGE>

     directly or indirectly, on this Mortgage or any of the Credit Documents or
     to require an amount of taxes to be withheld or deducted therefrom, the
     Grantor will promptly notify the Beneficiary of such event. In such event
     the Grantor shall (i) agree to enter into such further instruments as may
     be reasonably necessary or desirable to obligate the Grantor to make any
     applicable additional payments, and (ii) the Grantor shall make all such
     additional payments.

          (c) At any time that an Event of Default (as defined in Section 2.1
     herein) shall occur hereunder, or if required by any law applicable to the
     Grantor or to the Beneficiary, the Beneficiary shall have the right to
     direct the Grantor to make an initial deposit on account of real estate
     taxes and assessments, insurance premiums and common area charges, levied
     against or payable in respect of the Trust Property in advance and
     thereafter semi-annually, each such deposit to be equal to one-half of any
     such annual charges reasonably estimated by the Beneficiary in order to
     accumulate with the Beneficiary sufficient funds to pay such taxes,
     assessments, insurance premiums and charges.

     Section 1.4 Payment of Closing Costs. The Grantor shall pay all reasonable
                 ------------------------
costs in connection with, relating to or arising out of the preparation,
execution and recording of this Mortgage, including title company premiums and

engineers', appraisers' and consultants' fees and disbursements and all other
similar expenses of every kind.

     Section 1.5 Alterations and Waste; Plans; Use.
                 ---------------------------------

          (a) No Improvements will be materially altered or demolished or
     removed in whole or in part by the Grantor. The Grantor will maintain and
     keep the Trust Property in good condition and repair and will not commit
     any waste on the Trust Property or make any alteration to, or change in the
     use of, the Trust Property that will diminish the utility thereof for the
     operation of the business conducted thereon or materially increase the risk
     of fire or other hazard and in no event shall any such alteration or change
     be contrary to the terms of any insurance policy required to be kept
     pursuant to Section 1.6 hereof.

          (b) To the extent the same exist on the date hereof or are obtained in
     connection with future permitted alterations, the Grantor shall maintain a
     complete set of final plans, specifications, blueprints and drawings for
     the Improvements either at the Trust Property or in a particular office at
     the headquarters of the Grantor to which the Beneficiary shall have access
     upon reasonable advance notice.

          (c) The Grantor shall cause the Premises and the Improvements to be
     used in material compliance with all existing and future laws, codes,
     ordinances, rules, regulations, orders and decrees of governmental
     authorities and courts, having jurisdiction over the Trust Property or the
     Grantor and the requirements of all Permits. The Grantor shall promptly
     notify the Beneficiary of any proposed zoning reclassification, variance,
     conditional or special use permit, subdivision plat or annexation affecting
     the Land. The Grantor shall at all times comply with its obligations

                                       9
<PAGE>

     under all recorded restrictions, conditions, easements and covenants
     ("Restrictive Covenants") encumbering the Land and shall duly enforce its
       ----------- ---------
     rights under all Restrictive Covenants encumbering other property for the
     benefit of the Land and/or the Improvements. If the Grantor receives any
     notice (whether oral or written) that any Restrictive Covenant has been
     violated, which violation could in any material way affect title to the
     Land or the Grantor's existing or intended use of the Land or the
     Improvements or result in material liens, fines, penalties or encumbrances
     being imposed on the Land or Improvements, the Grantor shall promptly
     notify the Beneficiary and take such steps as the Beneficiary may
     reasonably require to correct such violation.

     Section 1.6 Insurance. The Grantor will keep the Trust Property insured
                 ---------
against such risks, and in the manner, required by Section 6.6 of the Credit
Agreement and Section 5.3 of the Participation Agreement. Without limiting the
generality of the Credit Agreement, Grantor shall, at its sole expense, obtain
and maintain in full force and effect during the existence of this Mortgage, the
following insurance coverages at limits not less than those specified herein:

          (a) Worker's Compensation Insurance providing statutory limits of
     liability and Employers' Liability Insurance with a limit of liability not
     less than the underlying limit required by the Umbrella Excess Liability
     Policy, as described in subsection (c) below. The Umbrella Excess Liability
     Policy shall be in addition to the required underlying limits.

          (b) Commercial General Liability Insurance for Bodily Injury and
     Property Damage with coverages extended and endorsements to the policy as
     stated below with a limit of liability not less than the underlying limit
     required by the Umbrella Excess Liability Policy, as described in
     subsection (c) below. The Umbrella Excess Liability Policy shall be in
     addition to the required underlying limits. The coverages to be included in
     this policy are: (i) Operations - Premises Liability, (ii) Independent
     Contractors Liability, (iii) Contractual Liability covering the Grantor's
     obligations as set forth herein, in the Credit Agreement and other Credit
     Documents, (iv) Personal Injury Liability extending to claims arising from
     employees of Grantor and (v) Products and completed operations hazards.

          (c) Excess Umbrella Liability Insurance coverage with a limit of
     liability of not less than $10,000,000 per occurrence.

          (d) Property insurance with coverage extended to the hazards described
     below on the Premises, Improvements and Personal Property in an amount not
     less than full replacement cost thereof. These policies shall provide that
     no deduction will be made for depreciation and shall contain no
     co-insurance penalty. The coverage shall be extended to the following: (i)
     Fire, extended (including vandalism and malicious mischief) and all risk
     coverage, (ii) Windstorm, hurricane and hail damage, (iii) Theft loss, (iv)
     Flood and (v) Business Interruptions.

coverages required by this Section shall be delivered to the

                                       10
<PAGE>

Beneficiary upon request. Copies of the insurance policies shall be available
for inspection and copying by the Beneficiary and its agents at the Grantor's
corporate headquarters during reasonable business hours. All policies shall be
taken out with insurers that are reasonably acceptable to the Beneficiary and in
a form reasonably satisfactory to the Beneficiary and shall provide that the
Beneficiary is an additional insured, as its interests may appear for the
policies described in subsections (a) through (c) above, and a mortgagee and/or
loss payee under each of the policies described in subsection (d) above. All
liability policies shall contain a waiver of subrogation against the
Beneficiary. The Grantor shall use its best efforts to require that all policies
shall provide for a thirty (30) day advance written notice to the Beneficiary of
any renewal, cancellation or material change in the insurance policies; provided
                                                                        --------
that, in all events such policies shall provide for a minimum of ten (10) days
----
advance written notice to the Beneficiary of any renewal, cancellation or
material change in the insurance policies. For purposes of the foregoing
sentence, the Grantor's use of "best efforts" shall include, but is not limited
to, changing current or existing insurance carriers irrespective of whether
premiums are increased on account thereof. All such insurance required by this
Mortgage shall be provided by insurance companies licensed to do business in the
state where the Premises are located and shall have a Best's rating of A or
better, as shown in Best's Key Rating Guide, Property-Casualty, at the time of
issuance (or reissuance). The Grantor may maintain insurance required under this
Mortgage by means of one or more blanket insurance policies maintained by the
Grantor; provided, however, that (A) any such policy shall specify, or the
         --------  -------
Grantor shall furnish to the Beneficiary a written statement from the insurer so
specifying, the maximum amount of the total insurance afforded by such blanket
policy that is allocated to the Premises and the other Trust Property and any
sublimits in such blanket policy applicable to the Premises and the other Trust
Property, (B) each such blanket policy shall include an endorsement providing
that, in the event of a loss resulting from an insured peril, insurance proceeds
shall be allocated to the Trust Property in an amount equal to the coverages
required to be maintained by the Grantor as provided above and (C) the
protection afforded under any such blanket policy shall be no less than that
which would have been afforded under a separate policy or policies relating only
to the Trust Property.

     Section 1.7 Casualty; Restoration of Casualty Damage. The Grantor shall
                 ----------------------------------------
give the Beneficiary prompt written notice of any material fire or other
material casualty to all or any portion of the Trust Property (a "Casualty").
                                                                  --------
For purposes hereof, a "material" fire or other casualty shall mean any such
event that disrupts operations at the Trust Property for more than two (2)
consecutive days. In the event any Casualty triggers, or when taken together
with other events would trigger, a mandatory prepayment under either of Section
2.6 of the Credit Agreement or Section 2.6 of the ELLF Credit Agreement, then
payments made by the insurer with respect to that Casualty will be made directly
in its entirety to the Beneficiary and the proceeds relating to such Casualty
shall be held or applied by the Beneficiary in accordance with, as applicable,
Section 2.6(c) of the Credit Agreement or Section 2.6(b) of the ELLF Credit
Agreement. Otherwise, proceeds received by the Beneficiary from any Casualty
shall be paid to Grantor within five (5) Business Days after request.

     Section 1.8 Condemnation/Eminent Domain. The Grantor shall notify the
                 ---------------------------
Beneficiary promptly upon obtaining knowledge of any pending or threatened
condemnation or taking of all or any portion of the Trust Property (a
"Condemnation"). In the event any Condemnation triggers, or when taken together
 ------------
with other events would trigger, a mandatory prepayment under

                                       11
<PAGE>

either of Section 2.6 of the Credit Agreement or Section 2.6 of the ELLF Credit
Agreement, then payment of all proceeds from that Condemnation shall be made
directly in its entirety to the Beneficiary and shall be held or applied by the
Beneficiary in accordance with, as applicable, Section 2.6(c) of the Credit
Agreement or Section 2.6(b) of the ELLF Credit Agreement. Otherwise, proceeds
received by the Beneficiary from any Condemnation shall be paid to Grantor
within five (5) Business Days after request.

     Section 1.9 Assignment of Leases and Rents.
                 ------------------------------

          (a) The Grantor hereby irrevocably and absolutely grants, transfers
     and assigns to the Beneficiary all of its right, title and interest in and
     to all Leases, together with any and all extensions and renewals thereof
     for purposes of securing and discharging the performance by the Grantor of
     the Obligations. The Grantor has not assigned or executed any assignment
     of, and will not assign or execute any assignment of, any Lease or its
     respective Rents to anyone other than to the Trustee for the benefit of the
     Beneficiary.

          (b) Without the Beneficiary's prior written consent, the Grantor will
     not (i) modify, amend, terminate or consent to the cancellation or
     surrender of any Lease if such modification, amendment, termination or
     consent would, in the reasonable judgment of the Beneficiary, be adverse in
     any material respect to the Secured Parties, the value of the Trust
     Property or the liens and security interests created by this Mortgage or
     (ii) consent to an assignment of any tenant's interest in any Lease or to a
     subletting thereof covering a material portion of the Trust Property,
     except, in each case, as may be permitted by this Mortgage or the Credit
     Agreement.

          (c) Subject to Section 1.9(d) below, the Grantor has assigned and
     transferred to the Beneficiary all of the Grantor's right, title and
     interest in and to the Rents now or hereafter arising, it being intended
     that this assignment establish, subject to Section 1.9(d) below, an
     absolute transfer and assignment of all Rents and all Leases to the
     Beneficiary and not merely to grant a security interest therein. The
     Grantor shall have the license and right, subject to automatic revocation
     as provided in Section 1.9(d) below, to operate and rent, lease or let all
     or any portion of the Trust Property and to collect, but not more than one
     month prior to accrual, all of the Rents. As provided in Section 1.9(d)
     below, the license granted by this Section 1.9(c) is subject to automatic
     revocation and thereafter the Beneficiary may, in the Grantor's name and
     stead (with or without first taking possession of any of the Trust Property
     personally or by receiver as provided herein) operate the Trust Property
     and rent, lease or let, all or any portion of any of the Trust Property to
     any party or parties at such rental and upon such terms as the Beneficiary
     shall, in its sole discretion, determine, and may collect and have the
     benefit of all of such Rents arising from or accruing at any time
     thereafter or that may thereafter become due.

          (d) As long as no Event of Default has occurred and is continuing, the
     license granted under Section 1.9(c) above shall be effective and the
     Beneficiary shall not exercise any of its rights under Section 1.9(c)
     above, and the Grantor shall receive and collect the Rents accruing under
     any Lease pursuant to the revocable license granted therein; but upon the
     occurrence of any Event of Default, the license granted under

                                       12
<PAGE>

     Section 1.9(c) above shall be deemed to be automatically revoked and shall
     terminate automatically without notice and the Beneficiary shall be
     entitled to all of the Rents without the necessity of the Beneficiary's
     taking any action whatsoever, and the Rents shall thereupon be deemed to be
     cash collateral for all purposes, including without limitation for purposes
     of Section 363 of the Bankruptcy Code. Upon the occurrence and during the
     continuance of any Event of Default, the Beneficiary may receive and
     collect all Rents and enter upon the Premises and Improvements through its
     officers, agents, employees or attorneys for such purpose and for the
     operation and maintenance thereof. Upon the occurrence and during the
     continuance of any Event of Default, the Grantor hereby irrevocably
     authorizes and directs each tenant, if any, and each successor, if any, to
     the interest of any tenant under any Lease, respectively, to rely upon any
     notice of a claimed Event of Default sent by the Beneficiary to any such
     tenant or any of such tenant's successors in interest, and thereafter to
     pay Rents to the Beneficiary without any obligation or right to inquire as
     to whether an Event of Default actually exists and even if notice to the
     contrary is received from the Grantor, who shall have no right or claim
     against any such tenant or successor in interest for any such Rents so paid
     to the Beneficiary. Each tenant or any of such tenant's successors in
     interest from whom the Beneficiary or any officer, agent, attorney or
     employee of the Beneficiary shall have collected any Rents, shall be
     authorized to pay Rents to the Grantor only after such tenant or any of
     such tenant's successors in interest shall have received written notice
     from the Beneficiary that the Event of Default is no longer continuing,
     which notice the Beneficiary shall be obligated to give if the Beneficiary
     determines in its reasonable discretion that such Event of Default is no
     longer continuing (or if ordered by a court or arbitrator with
     jurisdiction), unless and until a further notice of an Event of Default is
     given by the Beneficiary to such tenant or any of such tenant's successors
     in interest.

          (e) The Beneficiary will not become a mortgagee in possession so long
     as it does not enter and take actual possession of the Trust Property. In
     addition, the Beneficiary shall not be responsible or liable for performing
     any of the obligations of the landlord under any Lease, for any waste by
     any tenants, or others, for any dangerous or defective conditions of any of
     the Trust Property, for negligence in the management, upkeep, repair or
     control of any of the Trust Property or any other act or omission by any
     other Person.

          (f) The Grantor shall furnish to the Beneficiary, within 30 days after
     a request by the Beneficiary to do so, a written statement containing the
     names of all tenants, subtenants and concessionaires of the Premises or
     Improvements, the terms of any Lease, the space occupied and the rentals or
     license fees payable thereunder.

          (g) If an Event of Default occurs, and if there is any applicable law
     requiring the Beneficiary or the Trustee to take actual or constructive
     possession of the Premises (or some action equivalent thereto, such as
     securing the appointment of a receiver) in order for the Beneficiary or the
     Trustee to "perfect" or "activate" its rights and remedies as set forth
     herein, the Grantor hereby waives the benefits of any such laws to the
     maximum extent allowable.

     Section 1.10 Restrictions on Transfers and Encumbrances. Except as
                  ------------------------------------------
permitted hereby, by the Credit Agreement, by the Security Agreement, by any
other applicable Credit Document or by any applicable Operative Agreement, the
Grantor shall not directly or indirectly sell, convey, alienate, assign, lease,
sublease, license, mortgage, pledge, encumber or otherwise transfer, create,
consent to or suffer the creation of any lien, charges or any form of
encumbrance upon any interest in or any part of the Trust Property, or be
divested of its title to the Trust Property or any interest therein in any
manner or way, whether voluntarily or involuntarily (other than resulting from a
taking), or engage in any common, cooperative, joint, timesharing or other
congregate ownership of all or part thereof; provided, however, that the Grantor
                                             --------  -------
may in the ordinary course of business, within reasonable commercial standards
and upon obtaining the prior written consent of the Beneficiary (which consent
shall not be unreasonably withheld or delayed), enter into easement agreements

materially or adversely affect the use and operation of the same (including
customary utility easements that service the Trust Property).

     Section 1.11 Security Agreement. This Mortgage is both a mortgage and grant
                  ------------------
of real property and a grant of a security interest in personal property, and
shall constitute and serve as a "Security Agreement" within the meaning of the
Uniform Commercial Code as adopted in the State wherein the Premises are located
(the "UCC"). The Grantor hereby grants unto the Beneficiary a security interest
      ---
in and to all the Trust Property described in this Mortgage that is not real
property, and simultaneously with the recording of this Mortgage, the Grantor
has filed or will file UCC financing statements, and will file continuation
statements prior to the lapse thereof, at the appropriate offices in the state
in which the Premises are located to perfect the security interest granted by
this Mortgage in all the Trust Property that is not real property. The Grantor
hereby appoints the Beneficiary as its true and lawful attorney-in-fact and
agent, for the Grantor and in its name, place and stead, in any and all
capacities, to execute any document and to file the same in the appropriate
offices (to the extent it may lawfully do so), and to perform each and every act
and thing requisite and necessary to be done to perfect the security interest
hereby granted. The Beneficiary shall have all rights with respect to the part
of the Trust Property that is the subject of a security interest afforded by the
UCC in addition to, but not in limitation of, the other rights afforded the
Trustee and the Beneficiary hereunder. The Grantor agrees, to the extent
permitted by law, that: (i) all of the goods described within the definition of
the word "Personal Property" are or are to become fixtures on the Land; (ii)
this Mortgage upon recording or registration in the real estate records of the
proper office shall constitute a financing statement filed as a "fixture filing"
within the meaning of Sections 9-313 and 9-402 of the UCC; (iii) the Grantor is
the record owner of the Premises; and (iv) the addresses of the Grantor and the
Beneficiary are as set forth on the first page of this Mortgage. Additionally,
this Mortgage shall constitute a financing statement covering fixtures and/or
minerals or the like (including oil and gas) and/or accounts resulting from the
sale thereof at the wellhead or minehead and, as such, shall be filed for record
in the real estate records of each county in which the Land, or any part
thereof, is located.

     Section 1.12 Filing and Recording. The Grantor will cause this Mortgage,
                  --------------------
any other security instrument creating a security interest in or evidencing the
lien hereof upon the Trust Property and each instrument of further assurance to
be filed, registered or recorded in such manner and in such places as may be
required by any present or future law in order to publish notice of and to
protect fully the liens and security interests of the Trustee and the
Beneficiary

                                       14
<PAGE>

hereby granted in and upon the Trust Property. The Grantor will pay all filing,
registration or recording fees, and all expenses incidental to the execution and
acknowledgment of this Mortgage, any deed of trust supplemental hereto, any
security instrument with respect to the Trust Property, and any instrument of
further assurance and all federal, state, county and municipal recording,
documentary or intangible taxes and other taxes, duties, imposts, assessments
and charges arising out of or in connection with the execution, delivery and
recording of this Mortgage, any deed of trust supplemental hereto, any security
instrument with respect to the Trust Property or any instrument of further
assurance.

     Section 1.13 Further Assurances. Upon demand by the Beneficiary, the
                  ------------------
Grantor will, at the sole cost of the Grantor and without expense to the Trustee
or the Beneficiary, do, execute, acknowledge and deliver all such further acts,
deeds, conveyances, deeds of trust, assignments, notices of assignment,
transfers and assurances as the Beneficiary shall from time to time reasonably
require for the better assuring, conveying, assigning, transferring and
confirming unto the Beneficiary and the Trustee the property and rights hereby
conveyed or assigned or intended now or hereafter so to be, or which the Grantor
may be or may hereafter become bound to convey or assign to the Trustee or the
Beneficiary, or for carrying out the intention or facilitating the performance
of the terms of this Mortgage, or for filing, registering or recording this
Mortgage, and on demand, the Grantor will also execute and deliver and hereby
appoints the Beneficiary as its true and lawful attorney-in-fact and agent for
the Grantor and in its name, place and stead, in any and all capacities, to
execute and file to the extent it may lawfully do so, one or more financing
statements, chattel mortgages or comparable security instruments reasonably
required by the Beneficiary to evidence or perfect the liens and security
interests hereby granted and to perform each and every act and thing requisite
and necessary to be done to accomplish the same.

     Section 1.14 Additions to Trust Property. All right, title and interest of
                  ---------------------------
the Grantor in and to all extensions, improvements, betterments, renewals,
substitutes and replacements of, and all additions and appurtenances to, the
Trust Property hereafter acquired by or released to the Grantor or constructed,
assembled or placed by the Grantor upon the Premises or the Improvements, and
all conversions of the security constituted thereby, immediately upon such
acquisition, release, construction, assembling, placement or conversion, as the
case may be, and in each such case without any further deed of trust,
conveyance, assignment or other act by the Grantor, shall become subject to the
liens and security interests of this Mortgage as fully and completely and with
the same effect as though now owned by the Grantor and specifically described in
the grant of the Trust Property above, but at any and all times the Grantor will
execute and deliver to the Beneficiary any and all such further assurances,
deeds of trust, conveyances or assignments thereof as the Beneficiary may

     hereafter permit or suffer any generation, treatment, use, storage,

     or soil vapor at, on, about, under or within the Trust Property (or any

     demand for performance thereof (or such shorter period of time as may be
     required under any applicable law, regulation, order or agreement),
     commence and thereafter diligently prosecute to completion all such
     Remedial Work unless the Grantor is contesting its obligation to perform
     such Remedial Work in good faith and through appropriate proceedings. All
     costs and expenses of such Remedial Work shall be paid by the Grantor. In

     near or emanating from the Trust Property, and shall promptly comply with
     its obligations under applicable law with respect thereto. For purposes of
     the foregoing, a "material liability" shall be defined as a loss, claim,
     cost, expense, charge, lien, fine, penalty or other disadvantage to the
     Grantor that exceeds $50,000. Upon posting security satisfactory to the
     Beneficiary, the Grantor may diligently pursue protest procedures as

                                                                   -----
     arising out of, attributable to, relating to, which may accrue out of, or
     which may result from (i) a violation or alleged violation of any
     Environmental Laws in connection with the Trust Property by any Person or
     entity or other source whether related or unrelated to the Grantor or (ii)
     the actual, threatened or alleged Release of Hazardous Materials (whether
     intentional or unintentional, direct or indirect, foreseeable or
     unforeseeable) to, from, on, within, in, under, near or affecting the Trust
     Property by any Person or entity or other source, whether related or
     unrelated to the Grantor. The foregoing indemnity shall survive the
     cancellation or satisfaction of this Mortgage, the satisfaction of the
     Obligations, the foreclosure or conveyance in lieu of foreclosure of all or
     any part of the Trust Property, or the exercise by the Trustee or the
     Beneficiary of any of the remedies available under this Mortgage, any of

     foregoing, the obligation to indemnify any Indemnified Person under this
     Section 1.16 shall not apply in respect of any loss, claim, damage or
     liability to the extent that a court of competent jurisdiction shall have
     determined by final and nonappealable judgment that such loss, claim,
     damage or liability resulted from (A) such Indemnified Person's willful
     misconduct or gross negligence or (B) a Hazardous Substance introduced to
     the Trust Property by any Indemnified Person after the Beneficiary takes
     possession of the Trust Property, whether by foreclosure or otherwise.

          (g) The Grantor agrees that the Beneficiary or any agent or
     representative acting on behalf of the Beneficiary may (but shall not be
     obligated to) enter upon the Premises and the Improvements at any time,
     after the occurrence of an Event of Default, to conduct such inspections
     and tests, at the Grantor's sole cost and expense, as may be desired by the
     Beneficiary to determine compliance with Environmental Laws. In the event
     any such inspections or tests reveal facts or circumstances that are
     required to be reported to governmental authorities under applicable laws,
     then the Grantor agrees to report those facts and circumstances in
     accordance with applicable laws.

                              DEFAULTS AND REMEDIES

     Section 2.1 Events of Default. It shall be an Event of Default under this
                 -----------------
Mortgage if (i) the Grantor fails to comply with, or otherwise defaults in, any
of the terms and provisions of this Mortgage, and such failure or default shall
continue unremedied for a period of thirty (30) days (or for any other grace
period that, under the terms of this Mortgage, is specifically applicable
thereto) after delivery of notice thereof from the Agent or any Lender to the
Grantor, or (ii) any Event of Default (as defined in the Security Agreement)
shall have occurred and be continuing.

     Section 2.2 Demand for Payment. Upon the occurrence of any Event of
                 ------------------
Default, in addition to any other rights and remedies the Beneficiary may have
pursuant to the Credit Agreement, the other Credit Documents or the Operative
Agreements, or as provided at law or in equity, and without limitation, the
Obligations and all other amounts payable with respect to the Loans, the Letters
of Credit, the Credit Agreement, this Mortgage, the other Credit Documents or
the Operative Agreements shall become due and payable as provided in the Credit
Agreement or any of the Operative Agreements. The Grantor shall pay to the
Beneficiary upon demand all such amounts and such further amounts as shall be
reasonably incurred (without regard to statutory presumption) to cover the costs
and expenses of collection, including reasonable attorneys' fees, disbursements
and expenses incurred by the Trustee or the Beneficiary. The Grantor hereby
waives notice of presentment, demand, protest, acceleration and notice of
acceleration. In case the Grantor shall fail forthwith to pay such amounts or
any amounts due under the Credit Agreement, any provision of this Mortgage, any
of the other Credit Documents or any of the Operative Agreements upon the
Beneficiary's demand, the Trustee or the Beneficiary, in addition to any other
rights or remedies provided herein or at law or equity, shall be entitled and
empowered to institute an action or proceedings at law or in equity as advised
by

                                       18

counsel for the collection of the sums so due and unpaid, to prosecute any such
action or proceedings to judgment or final decree, to enforce any such judgment
or final decree against the Grantor and to collect, in any manner provided by
law, all moneys adjudged or decreed to be payable.

     Section 2.3 Rights to Take Possession, Operate and Apply Revenues.
                 -----------------------------------------------------

          (a) If an Event of Default shall occur and be continuing, the Grantor
     shall, upon demand of the Beneficiary, forthwith surrender to the
     Beneficiary actual possession of the Trust Property and, if and to the
     extent permitted by applicable law, the Beneficiary itself, or by such
     officers or agents as it may appoint, may then enter and take possession of
     all the Trust Property with or without the appointment of a receiver or an
     application therefor, exclude the Grantor and its agents and employees
     wholly therefrom, and have access to the books, papers and accounts of the
     Grantor.

          (b) If the Grantor shall for any reason fail to surrender or deliver
     the Trust Property or any part thereof after such demand by the
     Beneficiary, the Beneficiary may obtain a judgment or decree conferring
     upon the Beneficiary the right to immediate possession or requiring the
     Grantor to deliver immediate possession of the Trust Property to the
     Beneficiary, to the entry of which judgment or decree the Grantor hereby
     specifically consents. The Grantor will pay to the Beneficiary, upon
     demand, all reasonable expenses of obtaining such judgment or decree,
     including compensation to the Beneficiary's attorneys (for reasonable fees
     actually incurred (not as imposed by statute)) and agents with interest
     thereon at the Default Interest Rate; and all such expenses and
     compensation shall, until paid, be secured by this Mortgage.

          (c) If an Event of Default shall occur and be continuing, the
     Beneficiary may hold, store, use, operate, manage and control the Trust
     Property, conduct the business thereof and, from time to time, (i) make all
     necessary, proper and reasonable maintenance, repairs, renewals,
     replacements, additions, betterments and improvements thereto and thereon,
     (ii) purchase or otherwise acquire additional fixtures, personalty and
     other property, (iii) insure or keep the Trust Property insured, (iv)
     manage and operate the Trust Property and exercise all the rights and
     powers of the Grantor to the same extent as the Grantor could in its own
     name or otherwise with respect to the same or (v) enter into any and all
     agreements with respect to the exercise by others of any of the powers
     herein granted to the Beneficiary, all as may from time to time be directed
     or determined by the Beneficiary to be in its best interest and the Grantor
     hereby appoints the Beneficiary as its true and lawful attorney-in-fact and
     agent, for the Grantor and in its name, place and stead, in any and all
     capacities, to perform any of the foregoing acts. Regardless of whether or
     not the Beneficiary has entered or taken possession, the Beneficiary may
     collect and receive all the Rents, issues, profits and revenues from the
     Trust Property, including those past due as well as those accruing
     thereafter, and, after deducting (i) all expenses of taking, holding,
     managing and operating the Trust Property (including compensation for the
     services of all persons employed for such purposes), (ii) the costs of all
     such maintenance, repairs, renewals, replacements, additions , betterments,
     improvements, purchases and acquisitions, (iii) the costs of insurance,
     (iv) such taxes, assessments and other similar charges as the Beneficiary
     may at its option pay, (v) other

                                       19
<PAGE>

     proper charges upon the Trust Property or any part thereof and (vi) the
     compensation, expenses and disbursements of the attorneys and agents of the
     Beneficiary, the Beneficiary shall apply the remainder of the moneys and
     proceeds so received first to the Beneficiary, for the ratable account of
     the Secured Parties, for the payment in full and satisfaction of the
     Obligations (such payments to be made in accordance with the Intercreditor
     Agreement (as defined herein)), and second, if there is any surplus, to the
     Grantor, subject to the entitlement of others thereto under applicable law.
     For purposes of this Mortgage, "Intercreditor Agreement" shall mean an
     intercreditor agreement between each of the Secured Parties and the
     Collateral Agent, initially dated as of the date of the Security Agreement,
     as amended, modified or supplemented from time to time.

          (d) Whenever, before any sale of the Trust Property under Section 2.6
     hereof, all Obligations that are then due shall have been paid and all
     Events of Default fully cured, the Beneficiary will surrender possession of
     the Trust Property back to the Grantor, its successors or assigns. The same
     right of taking possession shall, however, arise again if any subsequent
     Event of Default shall occur and be continuing.

     Section 2.4 Right to Cure the Grantor's Failure to Perform. Prior to the
                 ----------------------------------------------
occurrence of an Event of Default and upon five business days' notice to the
Grantor (except in the case of an emergency), or after the occurrence of an
Event of Default, at any time and without notice, should the Grantor fail in the
payment, performance or observance of any term, covenant or condition required
by this Mortgage, the Credit Agreement, any other Credit Document or the
Operative Agreements (with respect to the Trust Property), the Beneficiary may
pay, perform or observe the same, and all payments made or costs or expenses
incurred by the Beneficiary in connection therewith shall be secured hereby and
shall be, without demand, immediately repaid by the Grantor to the Beneficiary
with interest thereon at the Default Interest Rate. The Beneficiary shall make
the determination as to the necessity for any such actions and of the amounts to
be paid. Subject to the notice provisions of the first sentence of this Section
2.4, the Beneficiary is hereby empowered to enter and to authorize others to
enter upon the Premises or the Improvements or any part thereof for the purpose
of performing or observing any such defaulted term, covenant or condition
without having any obligation to so perform or observe and without thereby
becoming liable to the Grantor, to any Person in possession holding under the
Grantor or to any other Person.

     Section 2.5 Right to a Receiver. If an Event of Default shall occur and be
                 -------------------
continuing, the Beneficiary, upon application to a court of competent
jurisdiction, shall be entitled as a matter of right to the appointment of a
receiver to take possession of and to operate the Trust Property and to collect
and apply the Rents. The Grantor hereby consents to such appointment and
acknowledges and agrees that the Beneficiary shall be entitled to such
appointment without notice and without regard for the adequacy of security for
the Obligations or the solvency of the Grantor or any party liable for the
Obligations. The receiver shall have all of the rights and powers permitted
under the laws of the state wherein the Trust Property is located. The Grantor
will pay to the Beneficiary upon demand all expenses, including receiver's fees,
attorneys' fees and disbursements that are actually incurred (not as imposed by
statute), costs and agent's compensation incurred pursuant to the provisions of
this Section 2.5; and all such expenses shall

                                       20
<PAGE>

be secured by this Mortgage and shall be, without demand, immediately repaid by
the Grantor to the Beneficiary with interest thereon at the Default Interest
Rate.

     Section 2.6 Foreclosure and Sale.
                 --------------------

          (a) If an Event of Default shall occur and be continuing, the
     Beneficiary may elect to sell or to cause and direct the Trustee to sell
     the Trust Property or any part of the Trust Property by exercise of the
     power of foreclosure or of sale granted to the Beneficiary by applicable
     law, this Mortgage, the Security Agreement, any other applicable Credit
     Document or any applicable Operative Agreement. In such case, the Trustee
     or the Beneficiary may commence a civil action to foreclose this Mortgage,
     or the Trustee may proceed and sell the Trust Property, in accordance with
     applicable law, to satisfy any Obligation. The Trustee, or an officer
     appointed by a judgment of foreclosure to sell the Trust Property, may sell
     all or such parts of the Trust Property as may be chosen by the Trustee or
     the Beneficiary at the time and place of sale fixed by it in a notice of
     sale, either as a whole or in separate lots, parcels or items as the
     Trustee or the Beneficiary shall deem expedient, and in such order as it
     may determine, at public auction to the highest bidder. The Trustee or the
     Beneficiary or an officer appointed by a judgment of foreclosure to sell
     the Trust Property may postpone any foreclosure or other sale of all or any
     portion of the Trust Property by public announcement at such time and place
     of sale, and from time to time as permitted by applicable law thereafter
     may postpone such sale by public announcement or subsequently noticed sale.
     Except as otherwise required by applicable law, without further notice, the
     Trustee or the Beneficiary or an officer appointed to sell the Trust
     Property may make such sale at the time fixed by the last postponement, or
     may, in its discretion, give a new notice of sale. Any person, including
     the Grantor or the Beneficiary or any designee or affiliate thereof, may
     purchase any portion of the Trust Property at such sale.

          (b) The Trust Property may be sold subject to unpaid taxes and the
     Permitted Encumbrances, and after deducting all the costs, fees and
     expenses of the Trustee or the Beneficiary, including, without limitation,
     costs of evidence of title in connection with the sale, the Trustee or the
     Beneficiary or an officer that makes any sale shall apply the proceeds of
     sale in the manner set forth in Section 2.8 hereof.

          (c) Any foreclosure or other sale of less than the whole of the Trust
     Property or any defective or irregular sale made hereunder shall not
     exhaust the power of foreclosure or of sale provided for herein; and
     subsequent sales may be made hereunder until the Obligations have been
     satisfied, or the entirety of the Trust Property has been sold.

          (d) If an Event of Default shall occur and be continuing, the
     Beneficiary may, instead of, or in addition to, exercising the rights
     described in Section 2.6(a) above and either with or without entry or
     taking possession as herein permitted, proceed by a suit or suits in law or
     in equity or by any other appropriate proceeding or remedy (i) to
     specifically enforce payment of some or all of the terms of the Credit
     Documents or the performance of any term, covenant, condition or agreement
     of this Mortgage or any other

                                       21
<PAGE>

     right or (ii) to pursue any other remedy available to it, at law or in
     equity, all as the Beneficiary shall determine most effectual for such
     purposes.

     Section 2.7 Other Remedies.
                 --------------

          (a) In case an Event of Default shall occur and be continuing, the
     Beneficiary may also exercise, to the extent not prohibited by applicable
     law, any or all of the remedies available to a secured party under the UCC,
     including, to the extent not prohibited by applicable law, the following:

               (i) In the case of personal property, to exercise those rights
          and remedies under the Security Agreement.

               (ii) To make such payments and do such acts as the Beneficiary
          may deem necessary to protect its security interest in the Personal
          Property including paying, purchasing, contesting or compromising any
          encumbrance, charge or lien that is prior or superior to the security
          interest granted hereunder, and, in exercising any such powers or
          authority, paying all expenses incurred in connection therewith.

               (iii) To enter upon any or all of the Premises or Improvements to
          exercise the Beneficiary's rights hereunder.

          (b) In connection with a sale of the Trust Property and the
     application of the proceeds of sale as provided in Section 2.8 of this
     Mortgage, the Beneficiary shall be entitled to enforce payment of and to
     receive up to the principal amount of the Obligations, plus all other
     charges, payments and costs due under this Mortgage, and to recover a
     deficiency judgment for any portion of the aggregate principal amount of
     the Obligations remaining unpaid, with interest.

     Section 2.8 Application of Sale of Proceeds and Rents. After any
                 -----------------------------------------
foreclosure sale of all or any of the Trust Property, the Trustee or the
Beneficiary shall receive the proceeds of sale, no purchaser shall be required
to see to the application of the proceeds, and the Trustee or the Beneficiary
shall apply the proceeds of the sale together with any Rents that may have been
collected and any other sums that then may be held by the Trustee or the
Beneficiary under this Mortgage as follows:

          First, to the payment of the costs and expenses of such sale,

     to the Beneficiary (based on actual fees and expenses incurred), the
     Beneficiary's attorneys (based on actual fees and expenses incurred, not as
     imposed by statute) and agents, and of any judicial proceedings wherein the
     same may be made, and of all expenses, liabilities and advances made or
     incurred by the Beneficiary under this Mortgage, together with interest at
     the Default Interest Rate on all advances made by the Beneficiary,
     including all taxes or assessments (except any taxes, assessments or other
     charges subject to which the Trust Property shall have been sold) and the
     cost of removing any encumbrance (except any Permitted Encumbrance subject
     to which the Trust Property was sold);

          Second, to the Beneficiary for the ratable payment in full and
          ------

     to be made in accordance with any intercreditor agreement among the Secured
     Parties as may be in effect from time to time); and

          Third, to the person or persons entitled thereto under applicable law
          -----
     or as a court of competent jurisdiction may otherwise direct.

Except as required by applicable law, the Beneficiary shall have absolute
discretion as to the time of application of any such proceeds, moneys or
balances in accordance with this Mortgage. Upon any sale of the Trust Property
by the Trustee or the Beneficiary (including pursuant to a power of sale granted
by statute or under a judicial proceeding), the receipt of the Trustee or the
Beneficiary or of the officer making the sale shall be a sufficient discharge to
the purchaser or purchasers of the Trust Property so sold and such purchaser or
purchasers shall not be obligated to see to the application of any part of the
purchase money paid over to the Trustee or the Beneficiary or such officer or be
answerable in any way for the misapplication thereof.

For purposes of applying amounts in accordance with this Section, the
Beneficiary shall be entitled to rely upon any Secured Party that has (or whose
Affiliate has) entered into a Hedge Agreement with the Grantor for a
determination (which such Secured Party agrees to provide or cause to be
provided upon request of the Agent) of the outstanding Obligations owed to such
Secured Party or Affiliate thereof under any such Hedge Agreement. Unless it has
actual knowledge (including by way of written notice from any such Secured
Party) to the contrary, the Beneficiary, in acting hereunder, shall be entitled
to assume that no Hedge Agreements or Obligations in respect thereof are in
existence between any Secured Party or Affiliate thereof and the Grantor. If any
Secured Party that is a party to a Hedge Agreement with the Grantor (the
obligations of the Grantor under which are Obligations) ceases to be a Secured
Party, such former Secured Party shall nevertheless continue to be secured by
the Trust Property hereunder with respect to the Obligations under such Hedge
Agreement.

     Section 2.9 The Grantor as Tenant Holding Over. If the Grantor remains in
                 ----------------------------------
possession of any of the Trust Property after any foreclosure sale by the
Trustee or the Beneficiary, at the Beneficiary's election the Grantor shall be
deemed a tenant holding over and shall forthwith surrender possession to the
purchaser or purchasers at such sale or be summarily dispossessed or evicted
according to provisions of law applicable to tenants holding over.

     Section 2.10 Waiver of Appraisement, Valuation, Stay, Extension and
                  ------------------------------------------------------
Redemption Laws.
---------------

          (a) The Grantor will not object to any sale of the Trust Property
     pursuant hereto, and for itself and all who may claim under it, the Grantor
     waives, to the extent that it lawfully may, all right to have the Trust
     Property marshaled or to have the Trust Property sold as separate estates,
     parcels, tracts or units in the event of any foreclosure of this Mortgage.

          (b) To the full extent permitted by the law of the state wherein the
     Trust Property is located or other applicable law, neither the Grantor nor
     anyone claiming

                                       23
<PAGE>

     through or under it shall or will set up, claim or seek to take advantage
     of any appraisement, valuation, stay, extension, homestead-exemption or
     redemption laws now or hereafter in force in order to prevent or hinder the
     enforcement or foreclosure of this Mortgage, the absolute sale of the Trust
     Property or the final and absolute putting of the purchasers into
     possession thereof immediately after any sale; and the Grantor, for itself
     and all who may at any time claim through or under it, hereby waives to the
     full extent that it may lawfully do so, the benefit of all such laws and
     any and all right to have the assets covered by the security interest
     created hereby marshaled upon any foreclosure of this Mortgage.

     Section 2.11 Discontinuance of Proceedings. In case the Trustee or the
                  -----------------------------
Beneficiary shall proceed to enforce any right, power or remedy under this
Mortgage by foreclosure, entry or otherwise, and such proceedings shall be
discontinued or abandoned for any reason, or shall be determined adversely to
the Trustee or the Beneficiary, then and in every such case the Grantor, the
Trustee and the Beneficiary shall be restored to their former positions and
rights hereunder, and all rights, powers and remedies of the Trustee and the
Beneficiary shall continue as if no such proceeding had been taken.

     Section 2.12 Suits to Protect the Trust Property. The Trustee and/or the
                  -----------------------------------
Beneficiary shall have power (a) to institute and maintain suits and proceedings
to prevent any impairment of the Trust Property by any acts which may be
unlawful or in violation of this Mortgage, (b) to preserve or protect its
interest in the Trust Property and in the Rents arising therefrom and (c) to
restrain the enforcement of or compliance with any legislation or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid if the enforcement of or compliance with such enactment, rule or order
that may be unconstitutional or otherwise invalid if the enforcement of or
compliance with such enactment, rule or order would impair the security or be
prejudicial to the interest of the Trustee or the Beneficiary hereunder.

     Section 2.13 Filing Proofs of Claim. In case of any receivership,
                  ----------------------
insolvency, bankruptcy, reorganization, arrangement, adjustment, composition or
other proceedings affecting the Grantor, the Beneficiary shall, to the extent
permitted by applicable law, be entitled to file such proofs of claim and other
documents as may be necessary or advisable in order to have the claims of the
Beneficiary allowed in such proceedings for the Obligations secured by this
Mortgage at the date of the institution of such proceedings and for any interest
accrued, late charges and additional interest or other amounts due or that may
become due and payable hereunder after such date.

     Section 2.14 Possession by the Beneficiary. Notwithstanding the appointment
                  -----------------------------
of any receiver, liquidator or trustee of the Grantor, any of its property or
the Trust Property, the Beneficiary shall be entitled, to the extent not
prohibited by applicable law, to remain in possession and control of all parts
of the Trust Property now or hereafter granted under this Mortgage in accordance
with the terms hereof and applicable law.

     Section 2.15 Waiver.
                  ------

          (a) No delay or failure by the Trustee or the Beneficiary to exercise
     any right, power or remedy accruing upon any breach or Event of Default
     shall exhaust or impair

                                       24
<PAGE>

     any such right, power or remedy or be construed to be a waiver of any such
     breach or Event of Default or acquiescence therein; and every right, power
     and remedy given by this Mortgage to the Trustee or the Beneficiary may be
     exercised from time to time and as often as may be deemed expedient by the
     Trustee or the Beneficiary. No consent or waiver by the Beneficiary or the
     Trustee to or of any breach or default by the Grantor in the performance of
     the Obligations shall be deemed or construed to be a consent or waiver to
     or of any other breach or Event of Default in the performance of the same
     or any other Obligations by the Grantor hereunder. No failure on the part
     of the Beneficiary or the Trustee to complain of any act or failure to act
     or to declare an Event of Default, irrespective of how long such failure
     continues, shall constitute a waiver by the Beneficiary or the Trustee of
     its rights hereunder or impair any rights, powers or remedies consequent on
     any future Event of Default by the Grantor.

          (b) Even if the Beneficiary or the Trustee (i) grants some forbearance
     or an extension of time for the payment of any sums secured hereby, (ii)
     takes other or additional security for the payment of any sums secured
     hereby, (iii) waives or does not exercise some right granted herein or
     under the Credit Agreement, any of the other Credit Documents or any of the
     Operative Agreements, (iv) releases a part of the Trust Property from this
     Mortgage, (v) agrees to change some of the terms, covenants, conditions or
     agreements of the Credit Agreement, any of the Credit Documents or the
     Operative Agreement, (vi) consents to the filing of a map, plat or replat
     affecting the Premises, (vii) consents to the granting of an easement or
     other right affecting the Premises or (viii) makes or consents to an
     agreement subordinating the Beneficiary's lien on the Trust Property
     hereunder; no such act or omission shall preclude the Beneficiary or the
     Trustee from exercising any other right, power or privilege herein granted
     or intended to be granted in the event of any breach or Event of Default
     then made or of any subsequent default; nor, except as otherwise expressly
     provided in an instrument executed by the Trustee and the Beneficiary,
     shall this Mortgage be altered thereby. In the event of the sale or
     transfer by operation of law or otherwise of all or part of the Trust
     Property, the Beneficiary is hereby authorized and empowered to deal with
     any vendee or transferee with reference to the Trust Property secured
     hereby, or with reference to any of the terms, covenants, conditions or
     agreements hereof, as fully and to the same extent as it might deal with
     the original parties hereto and without in any way releasing or discharging
     any liabilities, obligations or undertakings.

     Section 2.16 Remedies Cumulative. No right, power or remedy conferred upon
                  -------------------
or reserved to the Trustee or the Beneficiary by this Mortgage is intended to be
exclusive of any other right, power or remedy, and each and every such right,
power and remedy shall be cumulative and concurrent and in addition to any other
right, power and remedy given hereunder or now or hereafter existing at law or
in equity or by statute.

Agreements is invalid or unenforceable in any jurisdiction or under any

created by this Mortgage is invalid or unenforceable, in whole or in part, as to
any part of the Obligations, or is invalid or unenforceable, in whole or in
part, as to any part of the Trust Property, such portion, if any, of the

paid prior to the payment of the portion of the Obligations and shall, unless
prohibited by applicable laws or unless Beneficiary, in its sole and absolute
discretion, otherwise elects, be deemed to have been first paid on and applied
to payment in full of the unsecured or partially secured portion of the
Obligations, and the remainder to the secured portion of the Obligations.

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

          (a) The conveyance to the Trustee of the Trust Property as security
     and for the benefit of the Beneficiary created and consummated by this
     Mortgage shall be null and void when all the Obligations have been
     indefeasibly paid in full in accordance with the terms of the Credit
     Agreement, the Credit Documents and the Operative Agreements, the
     Commitments have been terminated and all Letters of Credit have expired or
     been terminated, and all obligations of the Grantor under any Hedge
     Agreement with any Lender or any Affiliate of any Lender, which Hedge

     settled and such Hedge Agreement has been terminated.

          (b) In connection with any termination or release pursuant to
     subsection (a) above to the extent applicable, this Mortgage shall be
     marked "satisfied" by the Beneficiary and/or the Trustee, and this Mortgage

     shall execute any documents reasonably requested by the Grantor to
     accomplish the foregoing or to accomplish any release contemplated by
     subsection (a) or (b) of this Section 3.5, and the Grantor will pay all
     costs and expenses, including attorneys' fees and disbursements actually
     incurred (not as imposed by statute), incurred by the Beneficiary or the
     Trustee in connection with the preparation and execution of such documents.

     Section 3.7 The Credit Agreement, Other Credit Documents and the Operative
                 --------------------------------------------------------------
Agreements. The Grantor acknowledges that in addition to this Mortgage, the
----------
Credit Agreement, other Credit Documents and the Operative Agreements secure the
Obligations. The Grantor agrees that the lien of this Mortgage shall be absolute
and unconditional and shall not in any manner be affected or impaired by any
acts or omissions whatsoever of the Trustee or the Beneficiary and, without
limiting the generality of the foregoing, the lien hereof shall not be impaired
by any acceptance by the Trustee or the Beneficiary of any security for or
guarantees of any of the Obligations hereby secured, or by any failure, neglect
or omission on the part of the Trustee or the Beneficiary to realize upon or
protect any Obligation hereby secured or any collateral security therefor
including the Credit Agreement, the other Credit Documents and the Operative
Agreements. The lien hereof shall not in any manner be impaired or affected by
any release (except as to the property released), sale, pledge, surrender,
compromise, settlement, renewal, extension, indulgence, alteration, changing,
modification or disposition of any of the Obligations secured or of any of the
collateral security therefor, including the Credit Agreement, the other Credit
Documents or of any guarantee thereof, and the Operative Agreements, and the
Trustee or the Beneficiary may at its discretion foreclose, exercise any power
of sale, or exercise any other remedy available to it under the Credit
Agreement, any or all of the other Credit Documents or any or all of the
Operative Agreements without first exercising or enforcing any of its rights and
remedies hereunder. Such exercise of the Trustee's or the Beneficiary's rights
and remedies under the Credit Agreement, any or all of the other Credit
Documents or any of all of the Operative Agreements shall not in any manner
impair the Obligations hereby secured or the lien of this Mortgage and any
exercise of the rights or remedies of the Trustee or the Beneficiary hereunder
shall not impair the lien of the Credit Agreement, any of the other Credit
Documents, any of the Operative Agreements or any of the Trustee's or the
Beneficiary's rights and remedies

the Beneficiary may exercise its rights and remedies hereunder, under the Credit
Agreement, under the other Credit Documents and under the Operative Agreements
separately or concurrently and in any order that it may deem appropriate, and
the undersigned waives any rights of subrogation. In the event of a conflict
between the terms and provisions of this Mortgage, the Credit Agreement, the
Operative Agreements and the Intercreditor Agreement, the documents shall be
read together and construed, to the fullest, extent possible, to be in concert
with each other. In the event of a conflict that cannot be so resolved, the
terms and provisions of, first, the Intercreditor Agreement and, second, this
Mortgage shall control and govern.

     Section 3.8 The Trustee's Powers and Liabilities.
                 ------------------------------------

          (a) The Trustee, by acceptance hereof, covenants faithfully to perform
     and fulfill the trusts herein created, being liable, however, only for its
     gross negligence or willful misconduct. All authorities, powers and
     discretions given in this Mortgage to the Trustee and/or the Beneficiary
     may be exercised by either, without the other, with the same effect as if
     exercised jointly.

          (b) The Trustee may resign at any time upon giving 30 days' notice in
     writing to the Grantor and to the Beneficiary.

          (c) The Beneficiary may remove the Trustee at any time or from time to
     time and select a successor trustee. In the event of the death, removal,
     resignation, refusal to act, inability to act or absence of the Trustee
     from the state in which the premises are located, or in its sole discretion
     for any reason whatsoever, the Beneficiary may, upon notice to the Grantor
     and without specifying the reason therefor and without applying to any
     court, select and appoint a successor trustee, and all powers, rights,
     duties and authority of the former Trustee, as aforesaid, shall thereupon
     become vested in such successor. Such substitute trustee shall not be
     required to give bond for the faithful performance of his duties unless
     required by the Beneficiary. Such substitute trustee shall be appointed by
     written instrument duly recorded in the county where the Land is located.
     The Grantor hereby ratifies and confirms any and all acts that the herein
     named Trustee, or his successor or successors in this trust, shall do
     lawfully by virtue hereof. The Grantor hereby agrees, on behalf of itself
     and its heirs, executors, administrators and assigns, that the recitals
     contained in any deed or deeds executed in due form by any Trustee or
     substitute trustee, acting under the provisions of this instrument, shall
     be prima facie evidence of the facts recited, and that it shall not be
     necessary to prove in any court, otherwise than by such recitals, the
     existence of the facts essential to authorize the execution and delivery of
     such deed or deeds and the passing of title thereby.

          (d) The Trustee shall not be required to see that this Mortgage is
     recorded, nor be liable for its validity or its priority as a first deed of
     trust, or otherwise, nor shall the Trustee be answerable or responsible for
     performance or observance of the covenants and agreements imposed upon the
     Grantor or the Beneficiary by this Mortgage or any other agreement. The
     Trustee, as well as the Beneficiary, shall have authority in their
     respective discretion to employ agents and attorneys in the execution of
     this trust and to protect the interest of the Beneficiary hereunder, and to
     the extent permitted by applicable

                                       28
<PAGE>

     law they shall be compensated and all expenses relating to the employment
     of such agents and/or attorneys, including expenses of litigation, shall be
     paid out of the proceeds of the sale of the Trust Property conveyed hereby
     should a sale be had, but if no such sale be had, all sums so paid out
     shall be recoverable to the extent permitted by applicable law by all
     remedies at law or in equity.

          (e) At any time, or from time to time, without liability therefor and,
     with 10 days' prior written notice to the Grantor, upon written request of
     the Beneficiary and without affecting the effect of this Mortgage upon the
     remainder of the Trust Property, the Trustee may (i) reconvey any part of
     the Trust Property, (ii) consent in writing to the making of any map or
     plat thereof, so long as the Grantor has consented thereto, (iii) join in
     granting any easement thereon, so long as the Grantor has consented thereto
     or (iv) join in any extension agreement or any agreement subordinating the
     lien or charge hereof.

     Section 3.9 Subrogation. This Mortgage is made with full substitution and
                 -----------
subrogation of the Beneficiary in and to all covenants and warranties by others
heretofore given or made in respect of the Trust Property or any part thereof.
To the extent that proceeds of the Notes are used to pay any outstanding lien,
charge or prior encumbrance against the Trust Property, such proceeds have been
or will be advanced by the Beneficiary at the Grantor's request and the
Beneficiary shall be subrogated to any and all rights and liens held by any
owner or holder of such outstanding liens, charges and prior encumbrances,
irrespective of whether those liens, charges or encumbrances are released.

     Section 3.10 Beneficiary and Lender Powers. Without affecting the liability
                  -----------------------------
of any other Person liable for the payment of any obligations herein mentioned
and without affecting the lien or charge of this Mortgage upon any portion of
the Trust Property not then or theretofore released as security for the full
amount of all unpaid Obligations, from time to time, regardless of consideration
and without notice to or consent by the holder of any subordinate lien,
encumbrance, right, title or interest in or to the Trust Property, the
Beneficiary and/or the Secured Parties, or any of them, may (a) release any
persons liable for or on any Obligation, (b) extend the maturity or alter any of
the terms of any Obligation, (c) modify the interest rate payable on the
principal balance of the Obligations, (d) grant other indulgences, (e) release
or reconvey, or cause to be released or reconveyed at any time at the
Beneficiary's option any parcel, portion or all of the Trust Property, (f) take
or release any other or additional security for any obligations herein mentioned
or (g) make compositions or other arrangements with debtors in relation thereto.

     Section 3.11 Enforceability of Mortgage. This Mortgage is deemed to be and
                  --------------------------
may be enforced from time to time as an assignment, chattel mortgage, contract,
deed of trust, deed to secure debt, financing statement, real estate mortgage or
security agreement, and from time to time as any one or more thereof, as is
appropriate under applicable laws. A carbon, photographic or other reproduction
of this Mortgage or any financing statement in connection herewith shall be
sufficient as a financing statement for any and all purposes.

     Section 3.12 Amendments. No amendment, modification or waiver of any
                  ----------
provision of this Mortgage and no consent to any departure by the Grantor
therefrom shall in any event be

effective unless the same shall be in writing and shall be executed and
delivered in accordance with the Intercreditor Agreement, and then such
amendment, modification, waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given.

     Section 3.13 Applicable Law. THIS MORTGAGE SHALL BE GOVERNED BY AND
                  --------------
