                      EMPLOYMENT SEPARATION AGREEMENT AND
                        GENERAL RELEASE OF LEGAL RIGHTS

     This agreement and legal release ("Agreement") is entered into between
Formus Communications, Inc., (hereinafter the "Company") and Osmo Hautanen.
The purpose of this Agreement is to facilitate Mr. Hautanen's separation from
employment with the Company by providing him with severance pay and other
considerations in exchange for him giving up any legal rights he may have in
connection with his employment and separation from employment.

                                  I. RECITALS

1.   Mr. Hautanen is currently employed by the Company as its Chief Executive
Officer pursuant to a letter agreement dated July 1, 1998 (the "Letter
Agreement").

2.   Mr. Hautanen and the Company also entered into a Stock Option Agreement
dated July 1, 1998 (the "Stock Option Agreement").

3.   Mr. Hautanen and the Company now desire to terminate their
employer/employee relationship through this Agreement, to resolve completely
any and all issues related to that relationship, to incorporate certain terms
contained in the Letter Agreement, and to modify certain terms contained in the
Stock Option Agreement.

                                 II. AGREEMENT

     In consideration of the promises set forth below, Mr. Hautanen and the
Company agree as follows:
<PAGE>   2
1.    Resignation. Mr. Hautanen will resign his employment with the Company, and
with any affiliate of the Company by which he may have been employed, including
all officer and Board of Directors positions, with the exception of his position
as a member of the Board of Directors of Formus Communications, Inc. Mr.
Hautanen shall remain a member of the Company's Board of Directors subject to
immediate removal at any time at the sole discretion of a majority of the other
members of that board effective December 31, 1999 (the "Separation Date"). Mr.
Hautanen's last day of work shall be December 1, 1999, and the time between this
date and the Separation Date shall be deemed to be vacation. Mr. Hautanen agrees
to execute and deliver any other documents and take any other actions reasonably
requested by the Company to further evidence the transaction contemplated by
this Agreement.

2.    Severance Pay. The Company shall continue to pay Mr. Hautanen's salary in
the gross amount of $420,000 per annum, less customary and required withholding
in twenty-four equal payments on the Company's regularly scheduled pay dates,
commencing January 1, 2000 and ending December 31, 2000 (the "Salary
Continuation Period").

3.    Benefits Continuation. In addition to the severance payments described
above, Mr. Hautanen may elect to continue to participate in the Company's
medical, dental and Long Term Disability plans for a maximum of eighteen months.
If Mr. Hautanen elects to participate in these plans, the Company will continue
to pay the same portion of the premium it pays on behalf of its regular
employees for a period of twelve months, provided Mr. Hautanen continues to pay
his share of these premiums. If Mr. Hautanen becomes eligible for medical,
dental or Long Term Disability benefits through another employer, Mr. Hautanen
will no longer be eligible to continue participating in the Company's plans, and
if this occurs during the twelve-month period in which the Company is paying a
portion of the premiums for Mr. Hautanen, the obligation of the Company to pay
these premiums will cease.

4. Post Employment Office Support and Executive Coaching. The Company shall pay
for administrative/secretarial office support and executive coaching assistance
in an amount not to exceed $25,000, provided the assistance is obtained within
twelve months following the Separation Date. Invoices for these services shall
be sent directly to the Company and the Company shall pay the service provider
directly as they are incurred.

5. Relocation Assistance. In the event Mr. Hautanen elects to relocate and sell
his home in the Denver metropolitan area, the Company will pay reasonable and
customary closing costs associated with the sale of that home, so long as the
sale occurs within twelve months following the Separation Date.

6. Modification of Stock Option Agreements. Subject to approval by the
Company's Board of Directors, the Company and Mr. Hautanen hereby modify
paragraphs 2, 3, 5(d) and 6(c) of the Stock Option Agreement as provided in
this paragraph. As of the Separation Date, Mr. Hautanen shall become vested in
an additional 250,000 shares, in addition to those in which he is vested
pursuant to paragraph 2 of the Stock Option Agreement. The parties agree that
as of the Separation Date, this acceleration of the vesting of the Option means
that Mr. Hautanen shall be vested in 625,000 shares as of the Separation Date.
As an Option Holder, as that term is defined in the Stock Option Agreement, Mr.
Hautanen shall have the right to exercise the Options in which he is vested as
of his Separation Date within five years following the date of his Separation
but not thereafter, provided there is no change in control (as defined in
paragraph 5 of the Stock Option Agreement) prior to the exercise of the Option.
If a change in control or an underwritten public offering of the Common Stock
of the Company that is registered under the Securities Act of 1933, as amended,
occurs before the end of the five-year period, the Option

                                  Page 3 of 10
<PAGE>   4
shall terminate on the earlier of 90 days following the change in control or
underwritten public offering of the Common Stock, or the end of the five-year
period. If a change in control occurs within 365 days of the Separation Date,
then Mr. Hautanen shall become vested in an additional portion of the Options in
accordance with the schedule attached as Exhibit A. Paragraph 3 of the Stock
Option Agreement will be modified as follows: The outstanding loan shall be
repayable the earlier of (i) the date on which the Option Holder sells any of
the stock secured by the load in an amount proportionate to the amount of the
stock sold, and (ii) in its entirety, five years from the date of the loan, or
(iii) in its entirety within 90 days after Formus Communications stock becomes
publicly traded. The parties agree that the exercise and ownership of any shares
under the Stock Option Agreement shall be subject to all of the terms and
conditions of the Employee Stockholders Agreement Dated August 1, 1997, a copy
of which is attached as Exhibit C.

7. Confidential Information, Covenant Not to Compete, and Non-Solicitation. Mr.
Hautanen acknowledges that paragraph 6 of the Letter Agreement imposes certain
obligations on him regarding confidentiality, competition, discoveries and
non-solicitation. Mr. Hautanen and the Company incorporate paragraph 6 of the
Letter Agreement by reference, a copy of which is attached as Exhibit D, and
acknowledge and agree that the obligations contained therein survive the
termination of Mr. Hautanen's employment.

8. Approval of Press Release. Mr. Hautanen and the Company shall agree on the
contents of a press release to be issued by the Company regarding Mr. Hautanen's
separation from the Company.

SECTION 2. AMOUNT AND TERMS OF COMMITMENT AND LOANS; NOTES

              2.1 Loans and Notes.

              (1) Commitment. Subject to the terms and conditions of this
Agreement and in reliance upon the representations and warranties of the Company
herein set forth, the Lenders hereby agree to lend to the Company on the Lending
Date an aggregate amount of up to $75,000,000 (the "Loans"), each such Lender
committing to lend the amount set forth next to such Lender's name on the
signature pages hereto; provided that the Lending Date must occur no later than
June 30, 2000, and the Loans shall be in an aggregate amount of not less than
the lesser of (i) $37,500,000 or (ii) the amount of available Commitments (as
defined below) on the Lending Date. The Lenders' commitments to make the Loans
to the Company pursuant to this Section 2.1(a) are herein called individually,
the "Commitment" and collectively, the "Commitments."

              (2) Notice of Borrowing. When the Company desires to borrow under
this Section 2.1, it shall deliver to the Agent a Notice of Borrowing no later
than 11:00 A.M. (New York time), at least five (5) Business Days in advance of
the date of the proposed Lending Date or such later date as shall be agreed to
by the Agent. The Notice of Borrowing shall specify the proposed Lending Date
(which shall be a Business Day). Upon receipt of such Notice of Borrowing, the
Agent shall promptly notify each Lender of its share of the Loan and the other
matters covered by the Notice of Borrowing. Such Lender's share of the Loan
shall be determined by reference to the quotient of such Lender's unfunded
Commitment, divided by the aggregate amount of all unfunded Commitments. All
Loans shall be funded on a pro rata basis by the Lenders as aforesaid.

              (3) Disbursement of Funds. No later than 12:00 Noon (New York
time) on the Lending Date, each Lender will make available its pro rata share of
the Loan requested to be made on such date in the manner provided below. All
amounts shall be made available to the Agent in U.S. dollars and immediately
available funds at the Agent's Office and the Agent promptly will deliver by
wire transfer, to the account designated by the Company, the aggregate of the
amounts so made available in the type of funds received. Unless the Agent shall
have been notified by any Lender prior to the Lending Date that such Lender does
not intend to make available to the Agent its portion of the Loan to be made on
such date, the Agent may assume

                                       34
<PAGE>   41
that such Lender has made such amount available to the Agent on such date, and
the Agent, in reliance upon such assumption, may (in its sole discretion and
without any obligation to do so) make available to the Company a corresponding
amount. If such corresponding amount is not in fact made available to the Agent
by such Lender and the Agent has made available same to the Company, the Agent
shall be entitled to recover such corresponding amount from such Lender. If such
Lender does not pay such corresponding amount forthwith upon the Agent's demand
therefor, the Agent shall promptly notify the Company, and the Company shall
immediately pay such corresponding amount to the Agent; provided, that the
notice to the Company shall have been received not more than ten (10) Business
Days after the applicable Lending Date. The Agent shall also be entitled to
recover from the Lender or the Company, as the case may be, interest on such
corresponding amount in respect of each day from the date such corresponding
amount was made available by the Agent to the Company to the date such
corresponding amount is recovered by the Agent, at a rate per annum equal to (x)
if paid by such Lender, the overnight Federal Funds Rate or (y) if paid by the
Company, the then applicable rate of interest on the Loans.

              Nothing herein shall be deemed to relieve any Lender from its
obligation to fulfill its Commitment hereunder or to prejudice any rights which
the Company may have against any Lender as a result of any default by such
Lender hereunder.

              (4) Notes. The Company shall execute and deliver to each Lender on
the Closing Date a Note dated the Closing Date and having a principal amount
equal to such Lender's Commitment, substantially in the form of Exhibit I
annexed hereto (the "Original Notes"). On each interest payment date on which
the Company elects to pay a PIK Amount pursuant to Section 2.2(b), the Company
shall execute and deliver to each Lender on such interest payment date a Note
dated such interest payment date substantially in the form of Exhibit I annexed
hereto in a principal amount equal to such Lender's pro rata portion of such PIK
Amount and with other appropriate insertions (each, a "Subsequent Note" and,
together with the Original Bridge Notes, the "Notes"). A Subsequent Note shall
bear interest from the date of its issuance at the same rate borne by all Notes.

              (5) Scheduled Payment of Loan. The Company shall pay in full the
outstanding amount of the Loans and all other Obligations owing hereunder,
including, without limitation, the Prepayment Premium, if any, no later than the
Maturity Date.

              (6) Termination of Commitment. The Commitment hereunder shall
terminate on the earlier of (i) the commencement by the Company or any of its
Subsidiaries of the marketing of, or the issuance by the Company or any of its
Subsidiaries of, any Securities or the arrangement of any other financing for
the

                                       35
<PAGE>   42
Company or any of its Subsidiaries of which each of the Bridge Arrangers (or one
of their Affiliates) is not the sole joint lead underwriter, sole joint lead
initial purchaser or sole joint book running manager and, in the case of the
Co-Arranger, a co-manager, or, in the case of any bank financing, in which each
of the Bridge Arrangers is not sole joint syndication agent or arranger, and, in
the case of the Co-Arranger, sole co-arranger, as the case may be, (ii) upon the
Company or any of its Subsidiaries issuing Securities for gross proceeds of at
least $75,000,000, or (iii) June 30, 2000, if the Loans are not made on or
before such date (except for, in each case (A) any Incurrence of Equipment
Financing Obligations permitted under this Agreement, (B) Permitted Investments
and Asset Sales permitted under this Agreement, (C) as required pursuant to
shareholders agreements and joint venture agreements relating to Subsidiaries of
the Company entered into in the ordinary course of the business of the Company
and its Subsidiaries, and (D) any issuance of Securities of the Company in a
private placement to "accredited investors" (as defined in Regulation D under
the Securities Act of 1933) resulting in gross proceeds (together with the gross
proceeds of all such private placements on or subsequent to April 25, 2000) not
in excess of $200,000,000; provided that with respect to this clause (D), any
gross proceeds of all such private placements on or subsequent to April 25, 2000
in excess of $100,000,000 in the aggregate (the "Excess") shall be subject to
the mandatory reduction in Commitment and prepayment requirements set forth in
Section 2.4(d). The Company shall have the right, without premium or penalty, to
reduce or terminate the Commitment of the Lenders hereunder at any time upon at
least three (3) Business Days' notice to the Lenders. All Commitments not
utilized on the Lending Date shall immediately terminate.

              (7) Pro Rata Borrowings. The Loans made under this Agreement shall
be made by the Lenders pro rata on the basis of their respective Commitments. It
is understood that no Lender shall be responsible for any default by any other
Lender of its obligation to make its portion of the Loans hereunder and that
each Lender shall be obligated to make its portion of the Loans hereunder,
regardless of the failure of any other Lender to fulfill its commitments
hereunder.

              2.2 Interest on the Loans.

(1) Rate of Interest. The Loans shall bear interest on the unpaid principal
amount thereof from the date made through maturity (whether by prepayment,
acceleration or otherwise) at a rate determined as set forth below.

                   (1) Loans. The Loans shall bear interest for each Interest
Period at a rate per annum equal to the Applicable Rate for each relevant
Interest Period; provided that if Additional Loans are advanced, all Loans shall
at all times bear interest at the same rate as the Loans issued on the Lending
Date.

                                       36
<PAGE>   43
                   (2) Additional Loans. Notwithstanding the foregoing or any
other provision herein, in no event will the combined sum of interest (cash or
otherwise) on the Loans exceed seventeen percent (17.00%) per annum or be less
than thirteen percent (13.00%) per annum (in each case exclusive of the default
rate of interest payable pursuant to Section 2.2(c)). In addition, if and to the
extent that the amount of interest (exclusive of the default rate of interest
payable pursuant to Section 2.2(c)) payable on any Interest Payment Date is
greater than the amount of interest on the Loans which would have been payable
on such Interest Payment Date if the interest rate in effect at all times during
the three-month period then ended had been 15.00% per annum (the amount of such
excess being hereinafter referred to as the "PIK Amount" for such period), then
the Company may, at its option, in lieu of payment of the PIK Amount of interest
in cash, pay such PIK Amount by increasing the principal of the applicable Loans
by an amount equal to the PIK Amount (the "Additional Loans") and by issuance of
Subsequent Notes in an aggregate principal amount equal to the PIK Amount.
Notwithstanding anything to the contrary expressed or implied herein, such
Additional Loans made on any Interest Payment Date shall, subject to the
remaining provisions of this paragraph, bear interest at the same interest rate
as the Loans in respect of which such Additional Loans are being issued, shall
mature on the Maturity Date and be subject to prepayment and acceleration of
maturity in the same manner as the Loans, shall otherwise be identical to the
outstanding Loans and shall be deemed made by the applicable Lenders in
proportions such that each Lender shall receive the same ratio of cash interest
to Additional Loans on such Interest Payment Date.

              (2) Interest Payments. Interest shall be payable in arrears on the
last day of each Interest Period and upon any prepayment of the Loans (to the
extent accrued on the amount being prepaid) and at maturity of the Loans in
respect of any amounts paid on such date.

              (3) Default Rate. At any time that a Default or Event of Default
has occurred and is continuing, all Loans and other Obligations shall bear
interest payable upon demand at a rate which is 2.00% per annum in excess of the
rate of interest otherwise payable under this Agreement for the Loans.

              (4) Computation of Interest. Interest on the Loans shall be
computed on the basis of a 360-day year and the actual number of days elapsed in
the period during which it accrues. In computing interest on the Loans, the date
of the making of the Loans shall be included and the date of payment shall be
excluded; provided, however, that if a Loan is repaid on the same day on which
it is made, one day's interest shall be paid on that Loan.

              2.3 Fees. The Company agrees to pay to the Lenders all fees and
other obligations in accordance with, and at the times specified by, the Fee
Letter.

                                       37
<PAGE>   44
              2.4 Prepayments and Reductions in the Commitment.

              (1) Voluntary Prepayments. The Company at its option may, upon at
least ten (10) days' written notice to the Lenders, prepay all or any part of
the principal amount of outstanding Loans at a redemption price equal to 100% of
the principal amount of the Loans so prepaid plus the Prepayment Premium, if
applicable, together with accrued interest through the date of prepayment. Loans
so prepaid may not be reborrowed.

              (2) Mandatory Prepayments.

                   (1) Prepayments from Asset Sales. Except with respect to any
Asset Sale the Net Cash Proceeds of which are permitted to be reinvested in
Replacement Assets pursuant to Section 6.9(b) and which, at the time of such
Asset Sale, the Company intends to reinvest in Replacement Assets within ninety
(90) days as set forth in Section 6.9(b), the Company shall prepay Loans having
an aggregate principal amount equal to the Net Cash Proceeds of any Asset Sale
occurring after the Closing Date on a date not later than the fifth (5th)
Business Day next succeeding the date of consummation of such Asset Sale or, in
the case of that portion of the purchase price which is deferred, the date of
receipt of such Net Cash Proceeds, whichever is later. The Company shall also be
required to prepay Loans in the manner set forth above with any Net Cash
Proceeds of any Asset Sale which, at the time of the Asset Sale, the Company
intended to reinvest in Replacement Assets as permitted under Section 6.9(b) but
which were not reinvested in Replacement Assets as permitted under Section
6.9(b), and any such prepayment shall be made on or before the 90th day after
the applicable Asset Sale. At any time prior to the Lending Date, such Net Cash
Proceeds shall be applied to permanently reduce each Lender's Commitment on a
pro rata basis. Concurrently with the consummation of an Asset Sale, the Company
shall deliver to the Agent an Officer's Certificate demonstrating the derivation
of Net Cash Proceeds from the gross sales price of such Asset Sale.

                   (2) Prepayments from Issuances of Take-Out Securities.
Concurrently with the receipt by the Company or any Subsidiary of proceeds from
the issuance of Take-Out Securities or the sale, issuance or transfer of Capital
Stock (to the extent not constituting an Asset Sale) or the receipt by the
Company of proceeds from a capital contribution, the Company shall prepay the
Loans in a principal amount equal to the Net Cash Proceeds thereof. At any time
prior to the Lending Date, such Net Cash Proceeds shall be applied to
permanently reduce each Lender's Commitment on a pro rata basis.

                   (3) Prepayments from Incurrence of Indebtedness. Concurrently
with the Incurrence by the Company or any of its Subsidiaries of any
Indebtedness not permitted under Section 6.1, the Company shall prepay the Loans
in a principal amount equal to the principal amount of such Indebtedness so
Incurred.

                                       38
<PAGE>   45
At any time prior to the Lending Date, such Indebtedness Incurred shall be
applied to permanently reduce each Lender's Commitment on a pro rata basis.

                   (4) Notice. The Company shall notify the Agent of any
prepayment to be made pursuant to Section 2.4(b) at least two Business Days
prior to such prepayment date (unless shorter notice is satisfactory to the
Required Lenders).

              (3) Company's Mandatory Prepayment Obligation; Application of
Prepayments. All prepayments shall include: (i) payment of accrued interest on
the principal amount so prepaid (which shall be applied to payment of interest
before application to principal) and (ii) the Prepayment Premium, if applicable.
Loans so prepaid may not be reborrowed.

              (4) Mandatory Reduction in Commitments. In the event that
issuances of Securities of the Company in one or more private placements to
"accredited investors" (as defined in Regulation D under the Securities Act of
1933) on or subsequent to April 25, 2000 result in gross proceeds which exceed
$100,000,000 in the aggregate, concurrently with receipt by the Company or any
of its Subsidiaries of the Excess, the Required Amount shall be applied (i) at
any time prior to the Lending Date, first to permanently reduce the Commitments
in an amount equal to the Required Amount to the full extent thereof, and second
to prepay the Loans in a principal amount equal to any remaining portion of the
Required Amount, and (ii) on or after the Lending Date, to prepay the Loans in a
principal amount equal to the Required Amount.

              All prepayments of Loans shall include payment of accrued interest
on the principal amount so prepaid (which shall be applied to payment of
interest before application to principal) and the Prepayment Premium, if
applicable. Loans so prepaid may not be reborrowed. Notwithstanding anything to
the contrary contained herein, the Company shall not be required to pay any
Prepayment Premium in connection with any reduction in Commitments under this
Section 2.4(d). Loans prepaid hereunder may not be reborrowed. All reductions in
the Commitments shall apply to each Lender's Commitment on a pro rata basis.

              (5) Manner and Time of Payment. All payments of principal and
interest hereunder and under the Notes by the Company shall be made without
defense, set-off or counterclaim and in same-day funds and delivered to the
Agent, unless otherwise specified, not later than 12:00 Noon (New York time) on
the date due at the Agent's Office to such account as the Agent shall have
notified the Company for the account of the Lenders; funds received by the Agent
after that time shall be deemed to have been paid by the Company on the next
succeeding Business Day. Other than with respect to PIK Amounts, all payments of
any Obligations to be made hereunder or under the Notes by the Company or any
other obligor with respect thereto shall be made solely in U.S. Legal Tender or
such other currency as is

                                       39
<PAGE>   46
then legal tender for public and private debts in the United States of America.
The Company hereby authorizes the Agent to charge its account with the Agent in
order to cause timely payment to be made of all principal, interest and fees due
hereunder (subject to sufficient funds being available in its account for that
purpose).

              (6) Payments on Non-Business Days. Whenever any payment to be made
hereunder or under the Notes shall be stated to be due on a day which is not a
Business Day, the payment shall be made on the next succeeding Business Day and
such extension of time shall be included in the computation of the payment of
interest hereunder or under the Notes or of the commitment and other fees
hereunder, as the case may be. (1)

              (7) Notation of Payment. Each Lender agrees that before disposing
of any Note held by it, or any part thereof (other than by granting
participations therein), such Lender will make a notation thereon of all
principal payments previously made thereon and of the date to which interest
thereon has been paid and will notify the Company of the name and address of the
transferee of that Note; provided, however, that the failure to make (or any
error in the making of) such a notation or to notify the Company of the name and
address of such transferee shall not limit or otherwise affect the obligation of
the Company hereunder or under such Notes with respect to the Loans and payments
of principal or interest on any such Note.

              2.5 Use of Proceeds.

              (1) Loans. The proceeds of the Loans shall be used by the Company
for business development purposes, including the acquisition of wireless
spectrum licenses, as well as for general corporate purposes.

              (2) Margin Regulations. No portion of the proceeds of any
borrowing under this Agreement shall be used by the Company in any manner which
might cause the borrowing or the application of such proceeds to violate the
applicable requirements of Regulation T, Regulation U or Regulation X of the
Board of Governors of the Federal Reserve System or any other regulation of the
Board of Governors or to violate the Exchange Act, in each case as in effect on
the date or dates of such borrowing and such use of proceeds.

set forth in this Section 3.1 are satisfied on and as of the Closing Date.

              (18) The representations and warranties in Section 4 are true,

              (21) The making of the Loans in the manner contemplated in this

SECTION 4. REPRESENTATIONS AND WARRANTIES

carry on its business as now conducted and as proposed to be conducted and is
duly qualified as a foreign organization and in good standing in all
jurisdictions in which it is doing business, except where failure to be so
qualified or in good standing, singly or in the aggregate, could not reasonably
be expected to have a Material Adverse Effect.

                                       45
<PAGE>   52
                  4.2 Authorization and Power. Each of the Company and its
Subsidiaries, to the extent a party thereto, has the requisite power and
authority, and has taken all action necessary, to execute, deliver and perform
its obligations under the Loan Documents and to issue the Notes.

                  4.3      No Conflicts or Consents.

                  (1) The execution and delivery of the Loan Documents, the
consummation of each of the transactions herein contemplated, the compliance
with each of the terms and provisions hereof or thereof, and the issuance,
delivery and performance of the Notes, do not and will not (i) violate any
material provision of any Law or any governmental rule or regulation applicable
to any of the Company and its Subsidiaries, the Certificate or Articles of
Incorporation or By-laws or other organizational documents of any of them or any
order, judgment or decree of any court or other agency of government binding on
any of them, (ii) conflict with, result in a breach of or constitute (with due
notice or lapse of time or both) a default under any Permit or any Contractual
Obligation of any of the Company or its Subsidiaries, except for those
conflicts, breaches or defaults which would not result in a Material Adverse
Effect, (iii) result in or require the creation or imposition of any Lien upon
any of the properties or assets of any of the Company or its Subsidiaries except
for Liens created pursuant to this Agreement, (iv) require any approval of
stockholders or any approval or consent of any Person under any Permit or any
Contractual Obligation of any of the Company or its Subsidiaries except for such
approvals or consents which will be obtained on or before the Closing Date and
disclosed in writing to Lenders.

                  (2) No consent, approval, authorization or order of any
Tribunal or other Person is required in connection with the execution and
delivery by the Company or any of its Subsidiaries, to the extent a party
thereto, of the Loan Documents or the consummation of the transactions
contemplated hereby or thereby, other than any such consent, approval,
authorization or order which has been obtained and remains in full force and
effect.

                  4.4 Enforceable Obligations. Each of the Loan Documents and
each other document or instrument to be delivered in connection therewith has
been duly authorized; each of the Loan Documents and each other document or
instrument to be delivered in connection therewith to be executed and delivered
on or prior to the Closing Date has been duly executed and delivered by the
Company and each of its Subsidiaries that are a party thereto; and each of the
Loan Documents and each other document or instrument to be delivered in
connection therewith to be executed and delivered on or prior to the Closing
Date is, and each of the Loan Documents to be executed and delivered after the
Closing Date will be, upon such execution and delivery, the legal, valid and
binding obligations of the Company and each such

                                       46
<PAGE>   53
Subsidiary (to the extent a party thereto), enforceable in accordance with their
respective terms, except to the extent that the enforceability thereof may be
limited by applicable bankruptcy, insolvency, reorganization or similar Laws
affecting the enforcement of creditors' rights generally or by general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

                  4.5 Properties; Liens. Each of the Company and its
Subsidiaries has good, sufficient and legal title to all their respective
properties and assets, and all properties held under lease by any of them are
held under valid, subsisting and enforceable leases, and none of the Company or
its Subsidiaries is in default under any lease, except in each case for such
defects or defaults that, singly or in the aggregate, would not have a Material
Adverse Effect. Except for Permitted Liens, as reflected on Schedule D annexed
hereto, or as permitted by this Agreement, all such properties and assets owned
or leased are so owned or leased free and clear of Liens.

                  4.6      Financial Condition.

                  (1) The audited Financial Statements of the Company and its
Subsidiaries for the two-year period ended December 31, 1999, certified by the
Company's Auditors, copies of which have been delivered to the Agent, have been
prepared from, and are consistent with, the books and records of the Company and
its Subsidiaries and fairly present the consolidated financial position of the
Company and its Subsidiaries as at the respective dates thereof and the
consolidated results of operations and cash flows of the Company and its
Subsidiaries for the periods then ended, except as otherwise disclosed on
Schedule K. Except as disclosed on Schedule K, neither the Company nor any of
its Subsidiaries had at December 31, 1999, any material contingent liabilities,
liabilities for Taxes or long-term leases, unusual forward or long-term
commitments or unrealized or unanticipated losses from any unfavorable
commitments which are not reflected or reserved against in the foregoing
Financial Statements or in the notes thereto. No events or developments which
have had or could reasonably be expected to have a Material Adverse Effect have
occurred since December 31, 1999.

                  (2) The unaudited selected financial information of the
Company and its Subsidiaries meeting the requirements of Item 301(a) of
Regulation S-K for the three fiscal years immediately preceding the two fiscal
year period ended December 31, 1999 or since inception, whichever is less, a
copy of which has been delivered to the Agent, have been prepared from, and are
consistent with, the books and records of the Company and its Subsidiaries and
fairly present the consolidated financial position of the Company and its
Subsidiaries as of such date and the consolidated results of operations and cash
flows of the Company and its Subsidiaries for the period covered thereby,
subject to normal year-end audit adjustments, consistent with past practices.
Except as disclosed on Schedule K, neither the

                                       47
<PAGE>   54
Company nor any of its Subsidiaries had on such date any material contingent
liabilities, liabilities for Taxes or long-term leases, unusual forward or
long-term commitment or unrealized or unanticipated losses from any unfavorable
commitment which are not reflected or reserved against in the foregoing
statements or in the notes thereto.

                  (3) The pro forma balance sheet of the Company and its
Subsidiaries as of December 31, 1999, a copy of which has heretofore been
furnished to the Agent, fairly presents the estimated consolidated opening
balance sheet of the Company and its Subsidiaries assuming the Loans had been
made as of December 31, 1999, and the financial condition of the Company on the
Closing Date does not differ in any material respect from the information
therein set forth.

                  (4) Upon giving effect to the Loans:

                    (1) The fair saleable value of the assets of the Company and
each of its Subsidiaries, on a stand-alone basis, exceeds the amount that will
be required to be paid on or in respect of the existing debts and other
liabilities (including contingent liabilities) of such Person as they mature.

                    (2) The assets of each of the Company and its Subsidiaries,
on a stand-alone basis, do not constitute unreasonably small capital for any
such Person to carry out its business as now conducted and as proposed to be
conducted including the capital needs of any such Person, taking into account
the particular capital requirements of the business conducted by such Person,
and projected capital requirements and capital availability thereof in
accordance with the business plan of the Company and its Subsidiaries.

                    (3) The Company does not intend to, and does not intend to
permit any of its Subsidiaries to, incur debts beyond its ability to pay such
debts as they mature (taking into account the timing and amounts of cash to be
payable on or in respect of Indebtedness of each such Person). The cash flow of
the Company and each of its Subsidiaries, after taking into account all
anticipated uses of the cash of each such Person, will at all times be
sufficient to pay all amounts on or in respect of debt of each such company when
such amounts are required to be paid.

                    (4) The Company does not intend, and does not believe, that
final judgments against any of the Company or its Subsidiaries in actions for
money damages will be rendered at a time when, or in an amount such that, any
such Person will be unable to satisfy any such judgments promptly in accordance
with their terms (taking into account the maximum reasonable amount of such
judgments in any such actions and the earliest reasonable time at which such
judgments might be rendered). The cash flow of the Company and each of its
Subsidiaries, on a stand-alone basis, after taking into account all other
anticipated uses of the cash of each such Person (including the payments on or
in respect of Indebtedness referred to in

                                       48
<PAGE>   55
paragraph (iii) of this Section 4.6(d)), will at all times be sufficient to pay
all such judgments promptly in accordance with their terms.

                  4.7 Full Disclosure. The financial projections (including,
without limitation, the pro forma financial statements included therewith)
heretofore furnished to the Agent by the Company are complete, were prepared by
or under the direction of an officer of the Company and were prepared in good
faith on the basis of information and assumptions that the Company believed to
be fair, complete and reasonable as of the date of such information, and which
assumptions are believed to be fair, complete and reasonable as of the date
hereof. All other factual information heretofore or contemporaneously furnished
in writing by or on behalf of the Company or any of its Subsidiaries to the
Agent or Lenders for purposes of or in connection with this Agreement does not
contain any untrue statement of a material fact or omit to state any material
fact necessary to keep the statements contained herein or therein, in light of
circumstances under which they were made, from being misleading. No fact is
known, no condition exists nor has any event occurred which has not been
disclosed herein or in any other document, certificate or statement furnished to
the Agent or the Lenders for use in the transactions contemplated hereby which,
singly or in the aggregate, has had or could reasonably be expected to have a
Material Adverse Effect.

                  4.8 No Default. No event has occurred and is continuing which
constitutes a Default or an Event of Default.

                  4.9 Compliance with Contracts, Etc. None of the Company or any
of its Subsidiaries is in violation of (i) its certificate of incorporation,
by-laws or other organizational documents or (ii) any material provision of any
applicable Law, ordinance, administrative or governmental rule or regulation, or
(iii) any order, decree or judgment of any Tribunal having jurisdiction over any
of them; no event of default or event that but for the giving of notice or the
lapse of time, or both, would constitute an event of default exists under any
material Contractual Obligation of the Company or any of its Subsidiaries,
except for those which would not result in a Material Adverse Effect.

                  4.10 No Litigation. Except as described in Schedule E attached
hereto, there is no Litigation pending or, to the best knowledge of the Company
after due investigation, threatened, by, against, or which may relate to or
affect (a) any benefit plan of the Company or any of its Subsidiaries or any
fiduciary or administrator thereof, or (b) the Company or any of its
Subsidiaries which, singly or in the aggregate, would reasonably be expected to
have a Material Adverse Effect. There are no outstanding injunctions or
restraining orders prohibiting consummation of any of the transactions
contemplated by the Loan Documents. There are no unsatisfied judgments against
the Company or any of its Subsidiaries or any of their respective

                                       49
<PAGE>   56
businesses or activities in excess of $100,000. Except as specifically noted on
Schedule E, neither the Company nor any of its Subsidiaries has been advised
that there is a reasonable likelihood of an adverse determination of any
Litigation which adverse determination, should it occur, would have a Material
Adverse Effect.

                  4.11 Use of Proceeds; Margin Stock, Etc. The proceeds of the
Loans will be used solely for the purposes specified herein. None of such
proceeds will be used for the purpose of purchasing or carrying any Margin Stock
within the meaning of the applicable provisions of Regulation T, U or X, or for
the purpose of reducing or retiring any Indebtedness which was originally
incurred to purchase or carry a Margin Stock or for any other purpose which
might constitute this transaction a "purpose credit" within the meaning of the
applicable provisions of Regulation T, U or X. Neither the Company nor any of
its Subsidiaries has taken or will take any action which might cause any of the
Loan Documents to violate the applicable provisions of Regulation T, U or X, or
any other regulation of the Board of Governors of the Federal Reserve System.

                  4.12 Taxes. Except as set forth on Schedule L hereto, all Tax
returns required to be filed by the Company and each of its Subsidiaries have
been filed and all such re- turns are true, complete, and correct in all
material respects. All Taxes that are due or claimed to be due from the Company
and each of its Subsidiaries have been paid other than those (i) currently
payable without penalty or interest or (ii) being contested in good faith and by
appropriate proceedings and for which, in the case of both clauses (i) and (ii),
adequate reserves have been established on the books and records of the Company
and its Subsidiaries in accordance with GAAP. There are no proposed Tax
assessments against the Company or any of its Subsidiaries. To the best
knowledge and belief of the Company, the accruals and reserves on the books and
records of the Company and its Subsidiaries in respect of any Tax liability for
any Taxable period not finally determined are adequate to meet any assessments
of Tax for any such period.

                  4.13     ERISA.

                  (1) The Company, each Subsidiary and each of their respective
ERISA Affiliates are in compliance in all material respects with all applicable
provisions and requirements of the Internal Revenue Code and ERISA and the
regulations and published interpretations thereunder with respect to each
Employee Benefit Plan, and have performed all their obligations under each
Employee Benefit Plan.

                  (2) No ERISA Events have occurred or are reasonably expected
to occur which individually or in the aggregate resulted in or might reasonably
be expected to result in a liability of the Company or any Subsidiary of the
Company or

                                       50
<PAGE>   57
any of their respective ERISA Affiliates in excess of $500,000 during the term
of this Agreement.

                  (3) Except as disclosed on Schedule F annexed hereto and
except to the extent required under Section 4980B of the Internal Revenue Code,
no Employee Benefit Plan provides health or welfare benefits (through the
purchase of insurance or otherwise) for any retired or former employees of the
Company or any Subsidiary or any of their respective ERISA Affiliates.

                  (4) In accordance with the most recent actuarial valuations,
the Amount of Unfunded Benefit Liabilities individually or in the aggregate for
all Pension Plans (excluding for purposes of such computation any Pension Plans
which have a negative Amount of Unfunded Benefit Liabilities), does not exceed
$500,000.

                  (5) The Company and each of its Subsidiaries and each of the
Foreign Plans are in compliance in all material respects with all applicable
Laws and regulations with respect to the Foreign Plans and the terms of the
Foreign Plans, and all required contributions have been made to the Foreign
Plans.

                  4.14 Government Regulation. Neither the Company nor any of its
Subsidiaries is subject to regulation under the Public Utility Holding Company
Act of 1935, the Federal Power Act, the Investment Company Act of 1940 (as any
of the preceding acts have been amended) or other Law which regulates the

Loan Documents and (ii) if as of any date any Person other than a Subsidiary
owns or holds any such Indebtedness or any Person holds a Lien in respect of

the purchase, sale, lease or exchange of any property or the rendering of any
service) with, or for the benefit of, any of its Affiliates (each an "Affiliate
Transaction"), other than (x) Affiliate Transactions permitted under paragraph
(b) below and (y) Affiliate Transactions on terms that are no less favorable to
the Company or the applicable Subsidiary than those that might reasonably have
been obtained in a comparable transaction at such time on an arm's-length basis
from a Person that is not an Affiliate of the Company or such Subsidiary. All
Affiliate Transactions (and each series of related Affiliate Transactions which
are similar or part of a common plan) involving aggregate payments or other
property with a fair market value in excess of $5,000,000 (or the equivalent
amount in any other currency) shall be approved by the Board of Directors of the
Company or such Subsidiary, as the case may be, such approval to be

                                       71
<PAGE>   78
evidenced by a Board Resolution stating that such Board of Directors has
determined that such transaction complies with the foregoing provisions. If the
Company or any Subsidiary enters into an Affiliate Transaction (or a series of
related Affiliate Transactions related to a common plan) that involves an
aggregate fair market value of more than $10,000,000 (or the equivalent amount
in any other currency), the Company or such Subsidiary, as the case may be,
shall, prior to the consummation thereof, obtain a favorable opinion as to the
fairness of such transaction or series of related transactions to the Company or
the relevant Subsidiary, as the case may be, from a financial point of view,
from an Independent Financial Advisor and provide the same to the Agent;
provided, however, that a fairness opinion shall not be required with respect to
an Affiliate Transaction unless an executive officer, director or shareholder of
the Company (or an Affiliate of any of them) has an equity or debt interest in
the Affiliate party to the Affiliate Transaction (other than an indirect
interest held by virtue of an ownership interest in the Company).

                  (2) The restrictions set forth in clause (a) shall not apply
to (i) reasonable fees and compensation paid to and indemnity provided on behalf
of, officers, directors and employees of the Company or any of its Subsidiaries
as determined in good faith by the Company's Board of Directors or Senior
Officers in connection with compensation and retention of such Persons; (ii)
transactions exclusively between or among the Company and any of its
Subsidiaries or exclusively between or among any of the Subsidiaries of the
Company; provided such transactions are not otherwise prohibited by this
Agreement; (iii) Restricted Payments permitted by this Agreement; (iv) any
issuance of Securities or other payments, awards or grants in cash, Securities
or otherwise pursuant to, or the funding of, employment arrangements, stock
options and stock ownership plans of the Company entered into in the ordinary
course of business in connection with director, officer and employee
compensation and approved by the Board of Directors; and (v) loans and advances
to employees and officers of the Company and its Subsidiaries in the ordinary
course of business for bona fide business purposes not in excess of $2,000,000
(or the equivalent amount in any other currency) at any time outstanding.

                  6.7 Business Activities. The Company shall not, nor shall the
Company cause or permit any of its Subsidiaries to, directly or indirectly,
materially alter the nature of the consolidated business of the Company and its
Subsidiaries from that in existence as of the Closing Date or similar or related
businesses.

                  6.8 Amendments to Charter Documents. The Company shall not,
nor shall it cause or permit any of its Subsidiaries to, amend its certificate
of incorporation or by-laws or any other organizational document in any respect
which could be materially adverse to the interests of the Lenders.

                  6.9      Asset Sales.

<PAGE>   79
                  (1) The Company shall not, nor shall it cause or permit any of
its Subsidiaries to, directly or indirectly, consummate any Asset Sale unless
(i) the aggregate of all Asset Sales does not exceed $5,000,000 (or the
equivalent amount in any other currency), (ii) the Company or such Subsidiary,
as the case may be, receives consideration therefor at the time thereof at least
equal to the fair market value at the time of such Asset Sale of the property,
assets or stock that is the subject of such Asset Sale, (iii) at least 85% of
the consideration received therefor by the Company or such Subsidiary is in the
form of cash or Cash Equivalents, and (iv) all of the Net Cash Proceeds in
respect thereof are applied by the Company or a Subsidiary in accordance with
Section 2.4(b)(i).

                  (2) The restrictions set forth in clauses (a)(i), (iii) and
(iv) above shall not apply to any Capital Stock owned by FII or any Subsidiary
of FII or any Capital Stock issued by any Subsidiary of FII, so long as, (i) to
the extent such transfer is for cash consideration, the proceeds of such
transfer are used, within ninety (90) days following such transfer or issuance
by FII or Subsidiaries of FII or its Subsidiaries own equity, for the purpose of
developing the broadband telecommunications business of FII and its Subsidiaries
and (ii) to the extent such transfer is not for cash consideration, it consists
of assets that are acquired within ninety (90) days of such equity issuance or
transfer and are appropriate, in the judgment of the Board of Directors of the
Company, for the purpose of developing the broadband telecommunication business
of FII and its Subsidiaries ("Replacement Assets"); provided that (1) the
aggregate amount of cash consideration and the aggregate fair market value of
Replacement Assets received in connection with all such transactions (a) shall
not exceed $20,000,000 (or the equivalent amount in any other currency), except
as permitted pursuant to clause (2) below and (b) not invested in the broadband
telecommunications business of Formus Polska and Callino GmbH shall not exceed
$10,000,000 (or the equivalent amount in any other currency), (2) Capital Stock
of Formus Polska and Callino GmbH may be so transferred or issued so long as,
after giving effect to such transfer or issuance, the Company will continue to,
directly or through Wholly Owned Subsidiaries, beneficially own and control an
amount of common equity of such Subsidiary and an amount of votes ordinarily
entitled, in the absence of contingencies, to vote in the election of directors
of such Subsidiary and on the approval of other matters subject to stockholder
vote equal, in each case, to 51% of the amount of such equity and votes held by
the Company and its Subsidiaries as of the Closing Date hereof, and (3) the cash
or other proceeds of any transfer or issuance of Capital Stock in Formus Polska
and Callino GmbH shall be required to be invested in the broadband
telecommunications business of Formus Polska and Callino GmbH.

any Guarantor is a party shall for any reason fail to result in the Agent, for
the benefit of the Lenders, having a valid, first priority perfected Lien on the

on the Loans and an amount as liquidated damages for the loss of the bargain
evidenced hereby (and not as a penalty) equal to the amount that would be

occurrence of any Event of Default, and all other outstanding Obligations shall
automatically become

                                       76
<PAGE>   83
immediately due and payable, without presentment, demand, protest or other
requirements of any kind, all of which are hereby expressly waived by the
Company, and the Commitments of the Lenders hereunder shall thereupon terminate,
and (ii) upon the occurrence of any other Event of Default, the Agent shall,
upon written notice by Lenders holding in the aggregate more than 25% of the
outstanding principal amount of Loans, by written notice to the Company, declare
all of the unpaid principal amount of and accrued interest on the Loans and an
amount as liquidated damages for the loss of the bargain evidenced hereby (and
not as a penalty) equal to the amount that would be payable as a Prepayment
Premium by the Company determined as of the date of the occurrence of any Event
of Default, and all other outstanding Obligations to be, and the same shall
forthwith become, due and payable, and the Commitments of the Lenders hereunder
shall thereupon terminate. The provisions of clause (ii) above are subject to
the condition that if the principal of and accrued interest on all or any
outstanding Loans and the Prepayment Premiums and all other outstanding
Obligations have been declared immediately due and payable by reason of the
occurrence of any Event of Default other than an Event of Default described in
Sections 7.6 or 7.7, the Lenders holding in the aggregate more than 50% of the
outstanding principal amount of Loans may, by written instrument filed with the
Company, rescind and annul such declaration and the consequences thereof,
provided that at the time such declaration is annulled and rescinded:

                  (i) no judgment or decree has been entered for the payment of
         any monies due pursuant to the Loans or this Agreement;

                  (ii) all arrears of interest upon all the Loans and all other
         sums payable under the Loans and under this Agreement (except any
         principal, interest or Prepayment Premium on the Loans which has become
         due and payable solely by reason of such declaration under clause (ii)
         above) shall have been duly paid; and

                  (iii) each and every other Default and Event of Default shall
         have been made good, cured or waived pursuant to the terms of this
         Agreement;
and provided further, that no such rescission and annulment shall extend to or
affect any subsequent Default or Event of Default or impair any right consequent
thereto. If an Event of Default shall occur and for as long as such Event of
Default shall be continuing, DLJ Bridge shall have the right (in consultation
with the other Arrangers) to designate one (1) representative to serve on the
Company's Board of Directors; provided, however, that such right shall terminate
if the Arrangers no longer retain at least 50% of the aggregate principal amount
of outstanding Loans. If DLJ Bridge (in consultation with the other Arrangers)
elects to make such designation, DLJ Bridge shall provide written notice to the
Company of the designated representative. No later than five (5) Business Days
after DLJ Bridge provides such notice to

                                       77
<PAGE>   84
the Company, the Company shall provide written confirmation to DLJ Bridge that
such designated representative is a member of the Company's Board of Directors
and shall thereafter receive all notices and other benefits and rights of a
member of the Company's Board of Directors. The designated representative may be
replaced at any time at the sole election of DLJ Bridge by another
representative designated by DLJ Bridge.

SECTION 8. THE AGENT

                  8.1 Appointment. Each Lender hereby irrevocably designates and
appoints DLJ Bridge as Agent of such Lender to act as specified herein and in
the other Loan Documents, and each Lender hereby irrevocably authorizes DLJ
Bridge as the Agent to take such action on its behalf under the provisions of
this Agreement and the other Loan Documents and to exercise such powers and
perform such duties as are expressly delegated to the Agent by the terms of this
Agreement and the other Loan Documents, together with such other powers as are
reasonably incidental thereto. The Agent agrees to act as such upon the express
conditions contained in this Section 8. Notwithstanding any provision to the
contrary elsewhere in this Agreement or in any other Loan Document, the Agent
shall not have any duties or responsibilities, except those expressly set forth
herein or in the other Loan Documents, or any fiduciary relationship with any
Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or otherwise exist
against the Agent. The provisions of this Section 8 are solely for the benefit
of the Agent and the Lenders, and neither the Company nor any of its
Subsidiaries shall have any rights as a third party beneficiary of any of the
provisions hereof. In performing its functions and duties under this Agreement,
the Agent shall act solely as agent of the Lenders and the Agent does not assume
and shall not be deemed to have assumed any obligation or relationship of agent
or trust with or for the Company or any of its Subsidiaries.

                  8.2 Delegation of Duties. The Agent may execute any of its
duties under this Agreement or any other Loan Document by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties (including counsel to the Company). The Agent
shall not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care except to the extent
otherwise required by Section 8.3.

                  8.3 Exculpatory Provisions. Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be
(a) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Agreement or the other Loan Documents
(except for its or such Person's own gross negligence or willful misconduct as
finally and unappealably

                                       78
<PAGE>   85
determined by a court of competent jurisdiction) or (b) responsible in any
manner to any of the Lenders for any recitals, statements, representations or
warranties made by the Company or any of its Subsidiaries or any of their
respective officers contained in this Agreement, any other Loan Documents, or in
any certificate, report, statement or other document referred to or provided for
in, or received by the Agent under or in connection with, this Agreement or any
other Loan Document or for any failure of the Company or any of its Subsidiaries
or any of their respective officers to perform its obligations hereunder or
thereunder. The Agent shall not be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or the other Loan
Documents, or to inspect the properties, books or records of the Company or any
of its Subsidiaries. The Agent shall not be responsible to any Lender for the
effectiveness, genuineness, validity, enforceability, collectability or
sufficiency of this Agreement or any other Loan Document or for any
representations, warranties, recitals or statements made herein or therein or
made in any written or oral statement or in any financial or other statements,
instruments, reports, certificates or any other documents in connection herewith
or therewith furnished or made by the Agent to the Lenders or by or on behalf of
the Company or any of its Subsidiaries to the Agent or any Lender or be required
to ascertain or inquire as to the performance or observance of any of the terms,
conditions, provisions, covenants or agreements contained herein or therein or
as to the use of the proceeds of the Loans or of the existence or possible
existence of any Default or Event of Default.

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

                                       79

<PAGE>   86
                  8.5 Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Agent has actually received notice from a Lender or the
Company referring to this Agreement, describing such Default or Event of Default
and stating that such notice is a "notice of default." In the event that the
Agent receives such a notice, the Agent shall give prompt notice thereof to the
Lenders. The Agent shall take such action with respect to such Default or Event
of Default as shall be reasonably directed by the Required Lenders; provided,
that, as between the Agent and the Lenders 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.

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

                  8.7 Indemnification. The Lenders agree to indemnify the Agent
in its capacity as such ratably according to their respective "percentages" as
used in determining the Required Lenders at such time, from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, ex-

                                       80
<PAGE>   87
penses or disbursements of any kind whatsoever which may at any time (including,
without limitation, at any time following the payment of the Obligations) be
imposed on, incurred by or asserted against the Agent in its capacity as such in
any way relating to or arising out of this Agreement or any other Loan Document,
or any documents contemplated by or referred to herein or the transactions
contemplated hereby of any action taken or omitted to be taken by the Agent
under or in connection with any of the foregoing, but only to the extent that
any of the foregoing is not paid by the Company or any of its Subsidiaries;
provided, that no Lender shall be liable to the Agent for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting solely from the
gross negligence or willful misconduct of the Agent as finally and unappealably
determined by a court of competent jurisdiction. If any indemnity furnished to
the Agent for any purpose shall, in the opinion of the Agent be insufficient or
become impaired, the Agent may call for additional indemnity and cease, or not
commence, to do the acts indemnified against until such additional indemnity is
furnished. The agreements in this Section 8.7 shall survive the payment of all
Obligations.

                  8.8 Agent in Its Individual Capacity. The Agent and its
Affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the Company and its Subsidiaries as though the Agent were
not the Agent hereunder. With respect to the Loans made by it and all
Obligations owing to it, the Agent shall have the same rights and powers under
this Agreement as any Lender and may exercise the same as though it were not the
Agent and the terms "Lender" and "Lenders" shall include the Agent in its
individual capacity.

                  8.9 Resignation of the Agent; Successor Agent. The Agent may
resign as the Agent upon ten (10) days' notice to the Lenders and the Company.
Upon the resignation of the Agent, the Required Lenders shall appoint from among
the Lenders a successor Agent for the Lenders, whereupon such successor agent
shall succeed to the rights, powers and duties of the Agent, and the term
"Agent" shall include such successor Agent effective upon its appointment, and
the resigning Agent's rights, powers and duties as the Agent shall be
terminated, without any other or further act or deed on the part of such former
Agent or any of the parties to this Agreement. If no successor shall have been
so appointed by the Required Lenders and shall have accepted such appointment
within thirty (30) days after the retiring Agent gives notice of its
resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent or delegate its duties to the Lenders, whereupon such successor
agent or the Lenders, as the case may be, shall succeed to the rights, powers
and duties of the Agent, and the term "Agent" shall include such successor Agent
or the Lenders, as the case may be, effective upon its or their appointment, and

                                       81
<PAGE>   88
the resigning Agent's rights, powers and duties as the Agent shall be
terminated, without any other or further act or deed on the part of such former
Agent or any of the parties to this Agreement. After the resignation of the
Agent hereunder, the provisions of this Section 8 shall inure to its benefit as
to any actions taken or omitted to be taken by it while it was Agent under this
Agreement.

SECTION 9.        GUARANTEE

                  9.1 Unconditional Guarantee. Each Guarantor hereby
unconditionally, jointly and severally, guarantees (such guarantee to be
referred to herein as the "Guarantee") to each of the Lenders and to the Agent
and their respective successors and assigns, that the principal of and interest
and Prepayment Premium on the Loans will be promptly paid in full when due,
whether at maturity, by acceleration or otherwise and interest on the overdue
principal, if any, and interest on any interest, to the extent lawful, of the
Loans and all other obligations of the Company to the Lenders or the Agent
hereunder or thereunder (including the Obligations) will be promptly paid in
full or performed, all in accordance with the terms hereof and thereof; subject,
however, to the limitations set forth in Section 9.4. Each Guarantor hereby
agrees that its obligations hereunder shall be unconditional, irrespective of
the validity, regularity or enforceability of the Loans or this Agreement or any
other Loan Document, the absence of any action to enforce the same, any waiver
or consent by any of the Lenders with respect to any provisions hereof or
thereof, the recovery of any judgment against the Company, any action to enforce
the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a Guarantor. Each Guarantor hereby waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenants that this Guarantee will not be discharged except by complete
performance of the obligations (including, without limitation, payment of all
Obligations) contained in the Loans, this Agreement, the other Loan Documents
and in this Guarantee. If any Lender or the Agent is required by any court or
otherwise to return to the Company, any Guarantor, or any custodian, trustee,
liquidator or other similar official acting in relation to the Company or any
Guarantor, any amount paid by the Company or any Guarantor to the Agent or such
Lender, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. Each Guarantor further agrees that, as
between each Guarantor, on the one hand, and the Lenders and the Agent, on the
other hand, (x) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Section 7 for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby, and (y) in the
event of any acceleration of such

                                       82
<PAGE>   89
obligations as provided in Section 7, such obligations (whether or not due and
payable) shall forthwith become due and payable by each Guarantor for the
purpose of this Guarantee.

                  9.2 Severability. In case any provision of this Guarantee
shall be invalid, illegal or unenforceable, the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

                  9.3 Release of a Guarantor. Upon the sale or disposition
(whether by merger, stock purchase, asset sale or otherwise) of a Guarantor (or
all or substantially all its assets) to an entity which is not a Subsidiary of
the Company and which sale or disposition is otherwise in compliance with the
terms of this Agreement, such Guarantor shall be deemed released from all
obligations under this Section 9 without any further action required on the part
of the Agent or any Lender.

                  The Agent shall deliver an appropriate instrument evidencing
such release upon receipt of a request by the Company accompanied by an
Officers' Certificate certifying as to the compliance with this Section 9.3. Any
Guarantor not so released remains liable in all respects with respect to its
Guarantee as provided in this Section 9.

                  9.4 Limitation of Guarantor's Liability. Each Guarantor and,
by its acceptance hereof each of the Lenders, hereby confirms that it is the
intention of all such parties that the guarantee by such Guarantor pursuant to
its Guarantee not constitute a fraudulent transfer or conveyance for purposes of
any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform
Fraudulent Transfer Act or any similar Federal or state Law. To effect the
foregoing intention, the Lenders and such Guarantor hereby irrevocably agree
that the obligations of such Guarantor under the Guarantee shall be limited to
the maximum amount as will, after giving effect to all other contingent and
fixed liabilities of such Guarantor and after giving effect to any collections
from or payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under its Guarantee or pursuant to Section
9.5, result in the obligations of such Guarantor under the Guarantee not
constituting such fraudulent transfer or conveyance.

                  9.5 Contribution. In order to provide for just and equitable
contribution among the Guarantors, the Guarantors agree, inter se, that in the
event any payment or distribution is made by any Guarantor (a "Funding
Guarantor") under its Guarantee, such Funding Guarantor shall be entitled to a
contribution from all other Guarantors in a pro rata amount based on the
Adjusted Net Assets of each Guarantor (including the Funding Guarantor) for all
payments, damages and expenses incurred by that Funding Guarantor in discharging
the Company's obligations with respect to the Obligations. "Adjusted Net Assets"
of such Guarantor at any date shall mean the lesser of (x) the amount by which
the fair value of the property of

                                       83
<PAGE>   90
such Guarantor exceeds the total amount of liabilities, including, without
limitation, contingent liabilities (after giving effect to all other fixed and
contingent liabilities Incurred on such date (other than liabilities of such
Guarantor under Subordinated Indebtedness)), but excluding liabilities under the
Guarantee, of such Guarantor at such date and (y) the amount by which the
present fair salable value of the assets of such Guarantor at such date exceeds
the amount that will be required to pay the probable liabilities of such
Guarantor on its debts, excluding debt in respect of the Guarantee of such
Guarantor, as they become absolute and matured.

                  9.6 Waiver of Subrogation. Until such time as all Obligations
on the Loans are paid in full, each Guarantor hereby irrevocably waives any
claim or other rights which it may now or hereafter acquire against the Company
that arise from the existence, payment, performance or enforcement of such
Guarantor's obligations under its Guarantee and this Agreement, including,
without limitation, any right of subrogation, reimbursement, exoneration,
indemnification, and any right to participate in any claim or remedy of any
Lender against the Company, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from the Company, directly or indirectly, in cash
or other property or by set-off or in any other manner, payment or security on
account of such claim or other rights. If any amount shall be paid to any
Guarantor in violation of the preceding sentence and the Loans shall not have
been paid in full, such amount shall be deemed to have been paid to such
Guarantor for the benefit of, and held in trust for the benefit of, the Lenders,
and shall forthwith be paid to the Agent for the benefit of such Lenders to be
credited and applied upon the Loans, whether matured or unmatured, in accordance
with the terms of this Agreement. Each Guarantor acknowledges that it will
receive direct and indirect benefits from the financing arrangements
contemplated by this Agreement and that the waiver set forth in this Section 9.6
is knowingly made in contemplation of such benefits.

                  9.7 Waiver of Stay, Extension or Usury Laws. Each Guarantor
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, plead, or in any manner whatsoever claim or take the benefit
or advantage of, any stay or extension law or any usury law or other Law that
would prohibit or forgive such Guarantor from performing its Guarantee as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this Agreement; and (to the
extent that it may lawfully do so) each Guarantor hereby expressly waives all
benefit or advantage of any such Law, and covenants that it will not hinder,
delay or impede the execution of any power herein granted to the Agent, but will
suffer and permit the execution of every such power as though no such Law had
been enacted.

                                       84
<PAGE>   91
SECTION 10.       MISCELLANEOUS

                  10.1 Representation of the Lenders. Each Lender hereby
represents that it is a commercial lender which makes loans in the ordinary
course of its business and that it will make the Loans hereunder for its own
account or the account of its affiliates in the ordinary course of such
business.

                  10.2 Participations in and Assignments of Loans and Notes.

                  (1) Each Lender shall have the right at any time to sell,
assign, transfer or negotiate all or any portion of its Loans or Commitment in
an aggregate amount of not less than $2,500,000 to any Eligible Assignee. In the
case of any sale, transfer or negotiation of all or part of the Loans or any
Commitment authorized under this Section 10.2(a), the assignee, transferee or
recipient shall become a party to this Agreement as a Lender by execution of an
assignment and assumption agreement; provided that (i) at such time Section
2.1(a) shall be deemed modified to reflect the Commitment of such new Lender and
of the existing Lenders, (ii) upon surrender of the Notes, new Notes will be
issued, at the Company's expense, to such new Lender and to the assigning
Lender, such new Notes to be in conformity with the requirements of Section
2.1(d) (with appropriate modifications) to the extent needed to reflect the
revised Commitment, and (iii) the Agent shall receive at the time of each such
assignment, from the assigning or assignee Lender, the payment of a
non-refundable assignment fee of $3,500; and provided, further, that such
transfer or assignment will not be effective until recorded by the Agent on the
Register pursuant to Section 10.23. To the extent of any assignment pursuant to
this Section 10.2(a), the assigning Lender shall be relieved of its obligations
hereunder with respect to its assigned Commitment, and the assignee, transferee
or recipient shall have, to the extent of such sale, assignment, transfer or
negotiation, the same rights, benefits and obligations as it would if it were a
Lender with respect to such Loans or Commitment, including, without limitation,
the right to approve or disapprove actions which, in accordance with the terms
hereof, require the approval of a Lender. At the time of each assignment
pursuant to this Section 10.2(a) to an Eligible Assignee which is not already a
Lender hereunder and which is not a United States Person (as such term is
defined in Section 7701(a)(30) of the Internal Revenue Code) for Federal income
tax purposes, the respective Eligible Assignee shall provide to the Company and
the Agent the appropriate Internal Revenue Service Forms (and, if applicable, a
Section 10.2(e)(ii) Certificate) described in Section 10.2(e).

                  (2) Each Lender may grant participations in all or any part of
its Loans or its Commitment to any Person (a "participant"); provided, however,
that (i) such Lender's obligations under this Agreement shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations and (iii) the Company, the Agent and the
other Lenders shall

                                       85
<PAGE>   92
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under the Agreement and such Lender shall retain
the sole right to enforce the obligations of the Company relating to the Loans
and to approve any amendment, modification or waiver of any provision of this
Agreement (other than amendments, modifications or waivers with respect to any
fees payable hereunder or the amount of principal of or the rate at which
interest is payable on the Loans, or the dates fixed for payments of fees or
principal of or interest on the Loans or termination of the Commitment). The
Company agrees that each participant shall be entitled to the benefits of
Section 10.19 to the same extent as if it were a Lender and had acquired its
interest by assignment pursuant to Section 10.2(a); provided, however, that a
participant shall not be entitled to receive any greater payment under Section
10.19 than the applicable Lender would have been entitled to receive with
respect to the participation sold to such participant, unless the sale of the
participation to such participant is made with the Company's prior written
consent. To the extent permitted by law, each participant also shall be entitled
to the benefits of Section 10.5 as though it were a Lender, provided such
participant agrees to be subject to Section 10.18(b) as though it were a Lender.

                  (3) The Company shall, at its own cost and expense, provide
such certificates, acknowledgments and further assurances in respect of this
Agreement and the Loans as any Lender may reasonably require in connection with
any participation, transfer or assignment pursuant to this Section 10.2.

                  (4) Nothing in this Agreement shall prevent or prohibit any
Lender from pledging its Loan and Notes hereunder to a Federal Reserve Bank in
support of borrowings made by such Lender from such Federal Reserve Bank.

                  (5) Each Lender that is an assignee or transferee of an
interest under this Agreement pursuant to Section 10.2(a) (unless the respective
Lender was already a Lender hereunder immediately prior to such assignment or
transfer) and that is not a United States Person (as such term is defined in
Section 7701(a)(30) of the Internal Revenue Code) agrees to deliver to the
Company and the Agent, on the date of such assignment or transfer to such
Lender, (i) two accurate and complete original signed copies of Internal Revenue
Service Form 4224 (or W-8ECI) or 1001 (or W-8BEN) (or successor forms)
certifying to such Lender's entitlement to a complete exemption from United
States withholding tax with respect to payments to be made under this Agreement
and under any Note, or (ii) if the Lender is not a "bank" within the meaning of
Section 881(c)(3)(A) of the Internal Revenue Code and cannot deliver either
Internal Revenue Service Form 1001 (or W-8BEN) or 4224 (or W-8ECI) pursuant to
clause (i) above, two accurate and complete original signed copies of Internal
Revenue Service Form W-8 (or successor form) certifying to such Lender's
entitlement to a complete exemption from United States withholding tax

                                       86
<PAGE>   93
with respect to payments of interest to be made under this Agreement and under
any Note. In addition, each Lender agrees that, when a lapse in time or change
in circumstances renders the previous certification obsolete or inaccurate in
any material respect, it will deliver to the Company and the Agent two new
accurate and complete original signed copies of Internal Revenue Service Form
4224 (or W-8ECI) or 1001 (or W-8BEN), or Form W-8, as the case may be, and such
other forms as may be required in order to confirm or establish the entitlement
of such Lender to a continued exemption from or reduction in United States
withholding tax with respect to payments under this Agreement and any Note, or
it shall notify the Company and the Agent of its inability to deliver any such
Form or Certificate.

                  (6) In order to facilitate the sale or syndication of the
Loans, any of the Lenders may restructure the Loans made by such Lender into
different tranches, with different interest rates, rights to warrants and other
terms and conditions (which may include issuances of one or more tranches of
Notes or preferred equity securities) so long as the overall interest cost and
dilutive effect in respect of the Loans is not thereby increased.

                  10.3 Expenses. Whether or not the transactions contemplated
hereby shall be consummated, the Company agrees to promptly pay (a) all the
costs and expenses incurred by the Lenders in connection with the transactions
contemplated by the Loan Documents, including, without limitation, the
reasonable fees, expenses and disbursements of counsel to the Lenders (including
allocated costs of internal counsel) in connection with the negotiation,
preparation, execution and administration of the Loan Documents and the Loans
hereunder, and any amendments, modifications and waivers hereto or thereto and
consents to departures from the terms hereof and thereof; and (b) after the
occurrence of an Event of Default, all costs and expenses (including attorneys'
fees and costs of settlement) incurred by the Lenders or the Agent in enforcing
any Obligations of or in collecting any payments due from the Company or any
Guarantor hereunder or under the Notes or any other Loan Document by reason of
such Event of Default or in connection with any refinancing or restructuring of
the credit arrangements provided under this Agreement in the nature of a
"work-out" or in connection with any insolvency or bankruptcy proceedings.

                  10.4 Indemnity. In addition to the payment of expenses
pursuant to Section 10.3, whether or not the transactions contemplated hereby
shall be consummated, the Company agrees to indemnify, pay and hold each of the
Lenders, the Agent and any holder of any of the Notes, and each of their
respective officers, directors, employees, agents, representatives and
affiliates (collectively called the "Indemnitees"), harmless from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, claims, costs, expenses and disburse-

                                       87
<PAGE>   94
ments of any kind or nature whatsoever (including, without limitation, the
reasonable fees and disbursements of counsel for such Indemnitees in connection
with any investigative, administrative or judicial proceeding commenced or
threatened, whether or not such Indemnitee shall be designated as a party
thereto), which may be suffered by, imposed on, incurred by, or asserted against
that Indemnitee, in any manner resulting from, connected with, in respect of,
relating to or arising out of this Agreement, the other Loan Documents, the
Commitment Letter, the Lenders' agreements to make the Loans or the use or
intended use of any of the proceeds of the Loans hereunder or the issuance of
the Take-Out Securities (the "indemnified liabilities"); provided, however, that
the Company shall have no obligation to an Indemnitee hereunder with respect to
indemnified liabilities (a) to the extent such liabilities are finally and
unappealably judicially determined by a court of competent jurisdiction to have
resulted solely from the gross negligence or willful misconduct of that
Indemnitee or (b) in connection with the obligations of any Indemnitee under any
Loan Document or for any transfer fees. To the extent that the undertaking to
indemnify, pay and hold harmless set forth in the preceding sentence may be
unenforceable because it is violative of any law or public policy, the Company
shall contribute the maximum portion which it is permitted to pay and satisfy
under applicable law to the payment and satisfaction of all indemnified
liabilities incurred by the Indemnitees or any of them.

                  10.5 Setoff. In addition to any rights now or hereafter
granted under applicable Law and not by way of limitation of any such rights,
upon the occurrence and during the continuance of any Default or Event of
Default, each Lender, the Agent and each subsequent holder of any Note and any
Affiliate thereof is hereby authorized by the Company and the Guarantors at any
time or from time to time, without notice to the Company or any Guarantor, any
such notice being hereby expressly waived, to set off and to appropriate and to
apply any and all deposits (general or special, including, but not limited to,
Indebtedness evidenced by certificates of deposit, whether matured or unmatured)
and any other Indebtedness or obligations at any time held or owing by the
Agent, such Lender, such subsequent holder or such Affiliate to or for the
credit or the account of the Company or such Guarantor against and on account of
the obligations and liabilities of the Company or such Guarantor to the Lenders
under this Agreement, the Notes and the other Loan Documents, including, but not
limited to, all claims of any nature or description arising out of or connected
with this Agreement, the Notes, the Guarantees or the other Loan Documents,
irrespective of whether or not (a) the Agent, such Lender, such subsequent
holder or such Affiliate shall have made any demand hereunder or (b) the Agent,
such Lender, such subsequent holder or such Affiliate shall have declared the
principal of or the interest on its portion of the Loans and its Notes and

                                       88
<PAGE>   95
other amounts due hereunder to be due and payable as permitted by Section 7 and
although said obligations and liabilities, or any of them, may be contingent or
unmatured.

                  10.6 Amendments and Waivers. No amendment, modification,
termination or waiver of any term or provision of this Agreement, of the Notes,
any Guarantee or the Pledge Agreement or consent to any departure by the Company
or any Guarantor therefrom, shall in any event be effective without the prior
written concurrence of the Company or such Guarantor, as the case may be, and
the Required Lenders, and, upon the request of any Lender, the receipt of a
written opinion of counsel of the Company addressed to the Lenders to the effect
that such amendment, modification, termination, waiver or consent does not
violate or conflict with any of the terms and provisions of any Contractual
Obligation of the Company; provided, however, that without the prior written
consent of each Lender affected, an amendment, modification, termination or
waiver of this Agreement, any Notes, any Guarantee, the Pledge Agreement or
consent to departure from a term or provision hereof or thereof may not: (a)
reduce the principal amount of Notes whose holders must consent to any such
amendment, modification, termination, waiver or consent; (b) reduce the rate of
or extend the time for payment of principal or interest on any Note; (c) reduce
the principal amount of any Note; (d) make any Note payable in money other than
that stated in the Note; (e) make any change in the definition of Change of
Control, in the last paragraph of Section 7 or in this Section 10.6; (f) reduce
the rate or extend the time of payment of fees or other compensation payable to
the Lenders hereunder (including the Prepayment Premium); (g) increase the
amount of the Commitment; (h) release all or substantially all or a material
portion of the collateral purported to be subject to the Liens of the Pledge
Agreement (other than releases necessary to effectuate transactions otherwise
permitted under this Agreement); or (i) change the definition of "Required
Lenders"; and provided, further, that without the consent of the Agent, no such
amendment, modification, termination or waiver may amend, modify, terminate or
waive any provision of Section 8 as the same applies to the Agent or any other
provision of this Agreement or any other Loan Document as it relates to the
rights or obligations of the Agent. Any waiver or consent shall be effective
only in the specific instance and for the specific purpose for which it was
given. No notice to or demand on the Company in any case shall entitle the
Company to any further notice or demand in similar or other circumstances. Any
amendment, modification, termination, waiver or consent effected in accordance
with this Section 10.6 shall be binding upon each Lender, and, if signed by the
Company or a Guarantor, on the Company and such Guarantor.

                  10.7 Independence of Covenants. All covenants hereunder shall
be given independent effect so that if a particular action or condition is not
permitted by

                                       89
<PAGE>   96
any of such covenants, the fact that it would be permitted by an exception to,
or be otherwise within the limitation of, another covenant shall not avoid the
occurrence of a Default or Event of Default if such action is taken or condition
exists. For the purpose of determining compliance with any covenant contained
herein, if an item meets the criteria of more than one type of exception
described in such covenants or the definitions used therein, the Company or the
Subsidiary in question shall have the right to determine in its sole discretion
the category to which such item applies and shall not be required to include the
amount and type of such item in more than one of such categories and may elect
to apportion such item between or among two or more of such categories otherwise
applicable.

                  10.8 Entirety. The Loan Documents and the Fee Letter embody
the entire agreement of the parties and supersede all prior agreements and
understandings, if any, relating to the subject matter hereof and thereof.

                  10.9 Notices. Unless otherwise provided herein, any notice or
other communications herein required or permitted to be given shall be in
writing and may be personally served or delivered, telecopied, or sent by mail
and shall be deemed to have been given when delivered in person, upon receipt of
telecopy against receipt of answer back or four Business Days after depositing
it in the mail, registered or certified, with postage prepaid and properly
addressed; provided, however, that notices to the Agent and the Lenders shall
not be effective until received. For the purposes hereof, the addresses of the
parties hereto (until notice of a change thereof is delivered as provided in
this Section 10.9) shall be set forth under each party's name on the signature
pages hereto.

                  10.10 Survival of Warranties and Certain Agreements.

                  (1) All agreements, representations and warranties made herein
shall survive the execution and delivery of this Agreement, the making of the
Loans hereunder and the execution and delivery of the Notes and, notwithstanding
the making of the Loans, the execution and delivery of the Notes or any
investigation made by or on behalf of any party, shall continue in full force
and effect. The closing of the transactions herein contemplated shall not
prejudice any right of one party against any other party in respect of anything
done or omitted hereunder or in respect of any right to damages or other
remedies.

                  (2) Notwithstanding anything in this Agreement or implied by
Law to the contrary, the agreements of the Company set forth in Sections 10.3,
10.4, 10.14, 10.15, 10.17 and 10.19 shall survive the payment of the Loans and
the Notes and the termination of this Agreement.

                  10.11 Failure or Indulgence Not Waiver; Remedies Cumulative.
No failure or delay on the part of the Agent or any Lender or any holder of any
Note in the exercise of any power, right or privilege hereunder, under a
Guarantee, under the

                                       90
<PAGE>   97
Pledge Agreement or under the Notes shall impair such power, right or privilege
or be construed to be a waiver of any default or acquiescence therein, nor shall
any single or partial exercise of any such power, right or privilege preclude
other or further exercise thereof or of any other right, power or privilege. All
rights and remedies existing under this Agreement, under a Guarantee, the Pledge
Agreement or the Notes are cumulative to and not exclusive of any rights or
remedies otherwise available.

                  10.12 Severability. In case any provision in or obligation
under this Agreement, under a Guarantee, the Pledge Agreement or the Notes shall
be invalid, illegal or unenforceable in any jurisdiction, the validity, legality
and enforceability of the remaining provisions or obligations, or of such
provision or obligation in any other jurisdiction, shall not in any way be
affected or impaired thereby.

                  10.13 Headings. Section and subsection headings in this
Agreement are included herein for convenience of reference only and shall not
constitute a part of this Agreement for any other purpose or given any
substantive effect.

                  10.14 Applicable Law. THIS AGREEMENT, EACH GUARANTEE, THE
PLEDGE AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND
ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK INCLUDING,
WITHOUT LIMITATION, SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL
OBLIGATIONS LAW.

                  10.15 Successors and Assigns; Subsequent Holders of Notes.
This Agreement shall be binding upon the parties hereto and their respective
successors and assigns and shall inure to the benefit of the parties hereto and
the permitted successors and assigns of the Lenders. The terms and provisions of
this Agreement, each Guarantee and the Pledge Agreement shall inure to the
benefit of any assignee or transferee of the Loans pursuant to Section 10.2(a),
and in the event of such transfer or assignment, the rights and privileges
herein conferred upon the Lenders shall automatically extend to and be vested in
such transferee or assignee, all subject to the terms and conditions hereof. In
determining whether the holders of a sufficient aggregate principal amount of
the Loans shall have consented to any action under this Agreement, any amount of
the Loans owned or held by the Company, any Guarantor or any of their respective
Affiliates shall be disregarded. The Company's rights or any interest therein
hereunder may not be assigned without the prior express written consent of each
of the Lenders.

                  10.16 Counterparts; Effectiveness. This Agreement and any
amendments, waivers, consents or supplements may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed and delivered shall be deemed an original, but all such
counter-

                                       91

parts together shall constitute but one and the same instrument. This Agreement
shall become effective upon the execution of a counterpart hereof by each of the
parties hereto, and delivery thereof to the Agent or, in the case of the
Lenders, written facsimile notice or telephonic notification (confirmed in
writing) of such execution and delivery. The Agent will give the Company and
each Lender prompt notice of the effectiveness of this Agreement.

                  10.17 Consent to Jurisdiction; Venue; Waiver of Jury Trial;
Currency.

                  (1) Any legal action or proceeding with respect to this
Agreement, any Note, any Guarantee or the Pledge Agreement may be brought in the
courts of the State of New York or of the United States for the Southern
District of New York, and, by execution and delivery of this Agreement, each of
the parties to this Agreement hereby irrevocably accepts for itself and in
respect of its respective property, generally and unconditionally, the
jurisdiction of the aforesaid courts. Each of the parties to this Agreement
hereby further irrevocably waives any claim that any such courts lack
jurisdiction over itself, and agrees not to plead or claim, in any legal action
or proceeding with respect to this Agreement, the Notes, the Guarantees or the
Pledge Agreement brought in any of the aforesaid courts, that any such court
lacks jurisdiction over such party. Each of the parties to this Agreement
irrevocably consents to the service of process in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, to such party, at its respective address for notices pursuant to
Section 10.9 or to the Process Agent in accordance with Section 10.17(d), such
service to become effective 30 days after such mailing. To the extent permitted
by Law, each of the parties to this Agreement hereby irrevocably waives any
objection to such service of process and further irrevocably waives and agrees
not to plead or claim in any action or proceeding commenced hereunder or under
any Note, any Guarantee or the Pledge Agreement that service of process was in
any way invalid or ineffective. Nothing herein shall affect the right of any
party to this Agreement to serve process in any other manner permitted by Law or
to commence legal proceedings or otherwise proceed against any party in any
other jurisdiction.

                  (2) Each of the parties to this Agreement hereby irrevocably
waives any objection which it may now or hereafter have to the laying of venue
of any of the aforesaid actions or proceedings arising out of or in connection
with this Agreement, the Notes, the Guarantees or the Pledge Agreement brought
in the courts referred to in clause (a) above and hereby further irrevocably
waives and agrees not to plead or claim in any such court that any such action
or proceeding brought in any such court has been brought in an inconvenient
forum.

                                       92
<PAGE>   99
                  (3) Each of the parties to this Agreement hereby irrevocably
waives all right to a trial by jury in any action, proceeding or counterclaim
arising out of or relating to this Agreement, the Notes, the Guarantees or the
Pledge Agreement or the transactions contemplated hereby or thereby.

                  (4) Each of the Company and the Guarantors hereby agrees that
service of all writs, process and summonses in any proceeding brought against it
in the State of New York may be made upon CT Corporation System, presently
located at 111 Eighth Avenue, New York, New York 10011 (the "Process Agent"),
and each of the Company and the Guarantors hereby has irrevocably appointed the
Process Agent as its agent and true and lawful attorney-in-fact in its name,
place and stead to accept such service of any and all such writs, process and
summonses, and agrees that the failure of the Process Agent to give any notice
to it of any such service of process shall not impair or affect the validity of
such service or of any judgment based thereon. Each of the Company and the
Guarantors agrees to maintain at all times an agent with an office in New York
to act as Process Agent as aforesaid. Nothing herein shall in any way be deemed
to limit the ability to serve any such writs, process and summonses in any other
manner permitted by applicable law.

                  (5) If for the purpose of obtaining judgment in any court it
is necessary to convert a sum due hereunder or under a Loan from one currency
into another currency, the Company and each Lender agree, to the fullest extent
that they may effectively do so, that the rate of exchange used shall be that at
which, in accordance with normal banking procedures, such Lender could purchase
the first currency with such other currency on the day two (2) Business Days
preceding the day on which final judgment is given.

                  (6) To the extent permitted by applicable law, the obligations
of the Company in respect of any sum payable by it to a Lender shall,
notwithstanding any judgment in a currency (the "Judgment Currency") other than
Dollars, be discharged only to the extent that on the Business Day following
receipt by such Lender of any sum adjudged to be so due in the Judgment
Currency, such Lender may, in accordance with normal banking procedures,
purchase Dollars with the Judgment Currency; if the amount of Dollars so
purchased is less than the sum originally due to the Lender in Dollars
(determined in the manner set forth in Section 10.17(e) above), the Company
agrees, as a separate obligation and notwithstanding any such judgment, to
indemnify the Lender against such loss, and if the amount of Dollars so
purchased exceeds the sum originally due to the Lender, such Lender agrees to
remit to the Company such excess; provided that the Lender shall have no
obligation to remit any such excess as long as the Company shall have failed to
pay such Lender any obligations due and payable under this Agreement, the other
Loan Documents or the Engagement Letter, in which case such excess may be
applied to

                                       93
<PAGE>   100
such obligations of the Company, in accordance with the terms of this Agreement,
the other Loan Documents and the Engagement Letter.

                  10.18 Payments Pro Rata.

                  (1) The Agent agrees that promptly after its receipt of each
payment of any interest or premium on or principal of the Loans from or on
behalf of the Company or any Guarantor, it shall, except as otherwise provided
in this Agreement, distribute such payment to the Lenders (other than any Lender
that has consented in writing to waive its pro rata share of such payment) pro
rata based upon their respective pro rata shares, if any, of such payment.

                  (2) Each of the Lenders agrees that, if it should receive any
amount hereunder (whether by voluntary payment, by realization upon security, by
the exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Loan Documents, or otherwise)
which is applicable to the payment of the principal of, or interest on, the
Loans of a sum which with respect to the related sum or sums received by other
Lenders is in a greater proportion than the total of such Obligations then owed
and due to such Lender bears to the total of such Obligations then owed and due
to all of the Lenders immediately prior to such receipt, then such Lender
receiving such excess payment shall purchase for cash without recourse or
warranty from the other Lenders an interest in the Obligations of the Company to
such Lenders in such amount as shall result in a proportional participation by
all of the Lenders in such amount; provided that, if all or any portion of such
excess amount is thereafter recovered from such Lender, such purchase shall be
rescinded and the purchase price restored to the extent of such recovery, but
without interest.

                  10.19 Taxes.

                  (1) Any and all payments by the Company hereunder or under any
of the other Loan Documents shall be made free and clear of and without
deduction or withholding for or on account of any and all present or future
Taxes, unless such deduction or withholding is required by Law or the
administration thereof and excluding in the case of each Lender and the Agent,
Taxes imposed on such Lender's or the Agent's net income and franchise taxes
imposed on such Lender or the Agent by the jurisdiction under the Laws of which
such Person is organized or any political subdivision thereof (all such
nonexcluded Taxes hereinafter referred to as "Covered Taxes"). If the Company
shall be required by Law or the administration thereof to deduct or withhold any
Covered Taxes from or in respect of any sum payable hereunder or under any other
Loan Document, (1) the sum payable shall be increased as may be necessary so
that after making all required deductions or withholdings (including deductions
or withholdings applicable to additional amounts paid under this paragraph), the
Lender receives an amount equal to the sum it would have

                                       94
<PAGE>   101
received if no such deduction or withholding had been made; (2) the Company
shall make such deductions or withholdings; and (3) the Company forthwith shall
pay the full amount deducted or withheld to the relevant authority in accordance
with applicable Law.

                  (2) The Company agrees to pay forthwith any present or future
stamp, duty or documentary taxes or any other excise or property taxes, charges
or similar levies (all such taxes, charges and levies hereinafter referred to as
"Other Taxes") imposed by any jurisdiction (or any political subdivision or
taxing authority thereof or therein) which arise from any payment made by the
Company hereunder or under any other Loan Document or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement or any
other Loan Document.

                  (3) The Company agrees to indemnify the Agent and each of the
Lenders for the full amount of Covered Taxes or Other Taxes not deducted or
withheld and paid by the Company in accordance with Section 10.19(a) and (b) to
the relevant authority and any Taxes other than Covered Taxes or Other Taxes
imposed by any jurisdiction on amounts payable by the Company under this Section
10.19 paid by the Lender or the Agent and any liability (including penalties,
interest, additions to tax and expenses) arising therefrom or with respect
thereto, whether or not any such Taxes or Other Taxes were correctly or legally
asserted. Payment under this indemnification shall be made within 30 days from
the date the Agent or such Lender makes written demand therefor. A certificate
as to the amount of such Taxes or Other Taxes and evidence of payment thereof
submitted to the Company shall be prima facie evidence, absent manifest error,
of the amount due from the Company to the Agent or such Lender.

                  (4) The Company shall promptly furnish to the Agent and each
of the Lenders the original or a certified copy of a receipt evidencing any
payment of Taxes or Other Taxes made by the Company.

                  (5) The provisions of this Section 10.19 shall survive the
termination of the Agreement and repayment of all Obligations.

                  10.20 Waiver of Stay, Extension or Usury Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, plead, or in any manner whatsoever claim or take the benefit
or advantage of, any stay or extension law or any usury law or other Law that
would prohibit or forgive the Company from paying all or any portion of the
principal of or interest on the Loans as contemplated herein, wherever enacted,
now or at any time hereafter in force, or which may affect the covenants or the
performance of this Agreement; and (to the extent that it may lawfully do so)
the Company hereby expressly waives all benefit or advantage of any such Law,
and covenants that it will not hinder, delay or

                                       95
<PAGE>   102
impede the execution of any power herein granted to the Agent, but will suffer
and permit the execution of every such power as though no such Law had been
enacted.

                  10.21 Requirements of Law. In the event that any change in Law
occurring after the date that any lender becomes a Lender party to this
Agreement with respect to such Lender shall, in the opinion of such Lender,
require that any Commitment of such Lender be treated as an asset or otherwise
be included for purposes of calculating the appropriate amount of capital to be
maintained by such Lender or any corporation controlling such Lender, and such
change in Law shall have the effect of reducing the rate of return on such
Lender's or such corporation's capital, as the case may be, as a consequence of
such Lender's obligations hereunder to a level below that which such Lender or
such corporation, as the case may be, could have achieved but for such change in
Law (taking into account such Lender's or such corporation's policies, as the
case may be, with respect to capital adequacy) by an amount deemed by such
Lender to be material, then from time to time following notice by such Lender to
the Company of such change in Law as provided in paragraph (b) of this Section
10.21, within fifteen (15) days after demand by such Lender, the Company shall
pay to such Lender such additional amount or amounts as will compensate such
Lender or such corporation, as the case may be, for such reduction.

                  10.22 Confidentiality. Each Lender shall hold all non-public
information obtained pursuant to the requirements of or in connection with this
Agreement which has been identified as confidential by the Company in accordance
with such Lender's customary procedures for handling confidential information of
this nature and in accordance with safe and sound banking practices, it being
understood and agreed by the Company that (a) in any event a Lender may make
disclosures reasonably required by any Eligible Assignee, transferee or
participant in connection with the contemplated assignment or transfer by such
Lender of any Loans or any participation therein or as required or requested by
any governmental agency or representative thereof or pursuant to legal process;
provided that unless specifically prohibited by applicable Law or court order,
each Lender shall notify the Company of any request by any governmental agency
or representative thereof (other than any such request in connection with any
examination of the financial condition of such Lender by such governmental
agency) for disclosure of any such non-public information prior to disclosure of
such information, (b) a Lender may share with any of its Affiliates, and such
Affiliates may share with any Lender, any information related to the Company or
the Company's or their respective Affiliates (including information relating to
creditworthiness) and (c) a Lender may make disclosures in connection with the
enforcement hereof or any litigation relating hereto or to any other Loan
Document; and provided, further, that in no event shall any Lender be

                                       96
<PAGE>   103
obligated or required to return any materials furnished by the Company or any of
its Subsidiaries. Notwithstanding the foregoing, each of the Lenders and the
Agent agree to keep all information relating to the WBD Line of Credit
(including the whole or any part of the WBD Line of Credit facility agreement or
any of the facility documents, whether in draft or final form) made available to
it (either before or after the date of the WBD Line of Credit facility agreement
or any of the facility documents) confidential and not to communicate or allow
communications of that information to any third party or use it for any purpose
except in connection with the transactions contemplated in the WBD Line of
Credit facility documents without the prior written consent of Westdeutsche
Landesbank (France) S.A., unless the exceptions and conditions outlined in
clause 34.1 of the WBD Line of Credit facility agreement and clause 14.1 of the
WBD Line of Credit security trust deed have been satisfied.

                  10.23 Register. The Company hereby designates the Agent to
serve as the Company's agent, solely for purposes of this Section 10.23, to
maintain a register (the "Register") on which it will record the Loans made by
each of the Lenders and each repayment in respect of the principal amount of the
Loans of each Lender. Failure to make any such recordation, or any error in such
recordation shall not affect the Company's obligations in respect of such Loans.
With respect to any Lender, the transfer of the Commitments of such Lender and
the rights to the principal of, and interest on, any Loan made pursuant to such
Commitments shall not be effective until such transfer is recorded on the
Register maintained by the Agent with respect to ownership of such Commitments
and Loans and prior to such recordation all amounts owing to the transferor with
respect to such Commitments and Loans shall remain owing to the transferor. The
registration of assignment or transfer of all or part of any Commitments and
Loans shall be recorded by the Agent on the Register only upon the receipt by
the Agent of a properly executed and delivered assignment and assumption
agreement pursuant to Section 10.2(a). Coincident with the delivery of such an
assignment and assumption agreement to the Agent for acceptance and registration
of assignment or transfer of all or part of a Loan, or as soon thereafter as
practicable, the assigning or transferor Lender shall surrender the Note
evidencing such Loan, and thereupon one or more new Notes of the same type and
in the same aggregate principal amount shall be issued to the assigning or
transferor Lender and/or the new Lender.
