validly prescribed by law which a court of




                                       33
<PAGE>   41

competent jurisdiction may deem applicable hereto, then, ipso facto, the
obligations to be fulfilled shall be reduced to an amount computed at the
highest rate of interest permissible under applicable law, and if for any reason
whatsoever any Purchaser shall ever receive as interest an amount which would be
deemed unlawful under such applicable law such interest shall be automatically
applied to the payment of principal of the Notes outstanding hereunder (whether
or not then due and payable), without prepayment charge, premium or penalty, and
not to the payment of interest, or shall be refunded to the Issuer if such
principal and all other Obligations of the Issuer to such Purchaser have been
paid in full.

Revenue Service or a court of competent jurisdiction).

               Section 2.9 Subordination. The Notes and all other Obligations of
the Credit Parties under the Note Documents are and shall at all times be and
remain subordinated and subject in right of payment to the extent and in the

then outstanding.

Section 3.2, the Issuer at its option may prepay within five (5) Business Days
of the consummation of a Qualified Public Offering up to 35% of the aggregate
outstanding principal amount of the Notes, together with accrued but unpaid
interest thereon, plus payment of a prepayment premium equal to 13.5% of the
aggregate principal amount of the Notes being prepaid at such time (the
"Qualified Public Offering Prepayment Premium"); provided that the prepayment is
financed solely with the proceeds of such Qualified Public Offering which
proceeds were, immediately prior to such purchase, contributed by the Parent to
the common equity capital of the Issuer in a manner satisfactory to the Required
Purchasers.

               Section 3.2 Notice of Prepayment of the Notes. The Issuer shall

the amount of accrued interest to be paid or anticipated to be paid on such
date, and (d) the amount of the Prepayment Premium or Qualified Public Offering
Prepayment Premium, if any, to be paid in connection therewith. Notice of
prepayment having been so given, the aggregate principal amount of the Notes so
to be prepaid as specified in such notice, together with interest accrued
thereon to such date fixed for prepayment, plus the applicable Prepayment
Premium or Qualified Public Offering Prepayment Premium, if any, shall become
due and payable on the specified prepayment date.

               Section 3.3 Scheduled Payments. On the Maturity Date, the unpaid
principal balance of the Notes to the extent not sooner paid or prepaid
hereunder, shall be paid in full, together with accrued interest and fees
thereon and all costs, expenses, indemnities and other Obligations outstanding
hereunder or under any other Note Document.

               Section 3.4 Taxes.

by any Credit Party under this Agreement, the Notes or any other Note Document
to each Purchaser shall be made free and clear of and without deduction for any
and all present or future Charges excluding Charges imposed on or measured by
the net income or capital of such Purchaser by the jurisdiction (or a political
subdivision thereof) in which such Purchaser is organized, or in which the
principal office or applicable lending office of such Purchaser is located (all
such non-excluded Charges being hereinafter referred to as "Taxes").

               (b) If any Credit Party shall be required by law to deduct any
Taxes imposed by any taxing authority or other Governmental Body from or in
respect of any sum payable under this Agreement, the Notes or any other Note
Document to any Purchaser, except as provided in subsection (f) of this Section
3.4, the sum payable to the Purchaser shall be increased as may be necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section 3.4), such Purchaser receives an
amount equal to the sum it would have received




                                       35
<PAGE>   43

had no such deductions been required, the Issuer shall make, or cause the
applicable Credit Party to make, such deductions and the Issuer shall pay, or
cause the applicable Credit Party to pay, the full amount deducted to the
relevant taxation authority or other Governmental Body in accordance with
applicable law.

               (c) In addition, to the extent not precluded from doing so
pursuant to applicable law, the Issuer agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges or similar
levies that arise from any payment made under this Agreement, the Notes or any
other Note Document or from the execution, delivery, enforcement or registration
of, or otherwise with respect to, this Agreement, the Notes or any other Note
Document, other than any transfer taxes payable in connection with a change in
the registered holder of any Notes (hereinafter referred to as "Other Taxes").

               (d) Except as provided in subsection (f) of this Section 3.4, to
the extent not precluded from doing so pursuant to applicable law the Issuer
will indemnify each Purchaser (and in the case of a Purchaser that is a
partnership, each partner of the partnership) for the full amount of Taxes or
Other Taxes imposed by any taxing authority or other Governmental Body and paid
by the Purchaser or partner, as applicable, and any liability (including
penalties, additions to tax, interest and expenses) arising therefrom or with
respect thereto, whether or not such Taxes or Other Taxes were correctly or
legally asserted. This indemnification shall be made within 30 days from the
date a Purchaser or partner, as applicable, makes written demand therefor.

               (e) Within 30 days after the date of any payment of Taxes or
Other Taxes, the Issuer will furnish to the applicable Purchaser the original or
a certified copy of any receipt evidencing payment thereof.

               (f) The Credit Parties shall have no obligation to pay additional
amounts in respect of Taxes imposed by the United States of America or any
taxing authority or other Governmental Body thereof ("U.S. Taxes") on any
Purchaser which is not a U.S. Person pursuant to subsection (b) of this Section
3.4, or to indemnify any Purchaser in respect of such U.S. Taxes pursuant to
subsection (d) of this Section 3.4, if such U.S. Taxes are imposed solely by
reason of such Purchaser's failure (1) to provide the relevant Credit Party,
immediately prior to the time such Person becomes a Purchaser, with two duly
completed copies of United States Internal Revenue Service Form W-8ECI or W-8BEN
or successor applicable form, as the case may be, certifying in each case that
such Purchaser is entitled to receive


                                       36
<PAGE>   44

payments under this Agreement without deduction or withholding of any United
States federal income taxes and Internal Revenue Service Form W-8 or W-9 or
successor applicable form, as the case may be, to establish an exemption from
United States backup withholding tax, or (2) to provide the relevant Credit
Party, on or before the date that any form previously supplied to such Credit
Party pursuant to this Section 3.4(f) expires or becomes obsolete or immediately
subsequent to the occurrence of any event requiring a change in the form most
recently supplied by it to such Credit Party, two further copies of such Form
W-8ECI or W-8BEN and Form W-8 or W-9, or successor applicable forms, certifying
that such Purchaser is entitled to receive payments under this Agreement without
deduction or withholding of any United States federal income taxes and is exempt
from United States backup withholding tax unless a change in treaty, law or
regulation has occurred after the date on which such Purchaser became a party
hereto and prior to the date on which the delivery of the forms required by this
Section 3.4(f)(2) would otherwise be due renders all such forms inapplicable or
prevents such Purchaser from duly completing and delivering any such form and
such Purchaser advises such Credit Party that it is no longer capable of
receiving payments without deduction or withholding.

               (g) Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 3.4
shall survive the payment in full of principal, interest, fees and any other
amounts payable hereunder (other than amounts payable pursuant to this Section
3.4).

               Section 3.5 Purchase of Notes. No Credit Party will, nor will
they permit any of their Subsidiaries or Affiliates to, acquire directly or
indirectly by purchase or prepayment or otherwise any of the outstanding Notes
or Warrants except (x) by way of payment or prepayment in accordance with the
provisions of such Notes and Warrants and of this Agreement or (y) to the extent
permitted by Section 13.5(c). If any Credit Party or any of their respective
Subsidiaries or Affiliates acquires any Notes pursuant to any such offer in
violation of this Section 3.5 or in any other manner, such Notes shall
thereafter be canceled and shall not be reissued, no Note shall be issued in
substitution therefor, and such Notes shall not be deemed to be outstanding for
any purpose under this Agreement.

assumptions, which such management reasonably believes as of June 15, 2000 were
fair and reasonable in all material respects over the entire period in light of
the historical financial performance and working capital position of the Credit
Parties and of then reasonably foreseeable business conditions, and represent
such management's reasonable estimate of the Credit Parties' future cash flows
for the entire period taken as a whole (after giving effect to the Transactions)

Multiemployer Plan is currently in reorganization or insolvency under and within
the meaning of Section 4241 or 4245 of ERISA or that such Multiemployer Plan
intends to terminate or has been terminated under Section 4041A of ERISA, except
for such non-compliances that could not reasonably be expected to have a
Material Adverse Effect;

               (v) each Credit Party and its ERISA Affiliates are in compliance

               (vi) the actuarial present value of all benefit liabilities (as
defined in Section 4001(a)(16) of ERISA) under each Pension Plan that is subject
to Title IV of ERISA does not exceed the Fair Market Value of the assets
allocable to such liabilities, determined as if such Pension Plan were
terminated as of the date hereof, and using such Pension Plan's actuarial

Pension Plan, except for non-compliances that could not reasonably be expected

Adverse Effect;

               (ix) except as described in Schedule 4.18, there are no

                                       47
<PAGE>   55

Affiliates or any of its directors, officers, employees or agents has engaged in
a transaction that subject the Parent, the Issuer, or any of their Subsidiaries,
directly or indirectly, to a material tax or civil penalty. With respect to each
Foreign Pension Plan, reserves have been established in the financial statements
furnished to Purchasers in respect of any unfunded liabilities in accordance
with applicable law and prudent business practice or, where required, in
accordance with ordinary accounting practices in the jurisdiction in which such
Foreign Pension Plan is maintained. The aggregate unfunded liabilities, with
respect to such Foreign Pension Plans could not reasonably be expected to result
in a Material Adverse Effect. There are no actions, suits or claims (other than
routine claims for benefits) pending or threatened against the Parent or any of
its Affiliates with respect to any Foreign Pension Plan which could reasonably
be expected, individually or in the aggregate, to result in a Material Adverse
Effect.

Parent and the Issuer no third party to any of such Material Contracts is in

(i) Intellectual Property owned by the Credit Parties, and applications for any
thereof, and all (ii) License Agreements with respect to Intellectual Property
used in the business of the Credit Parties, specifying with respect to each such
item the owner thereof, the registration or application number thereof, the
jurisdiction by or in which such item has been issued or registered or in which
an application therefor has been filed, if any, the date of such issuance,
registration or application, and the expiration date thereof, other than (x)
Intellectual Property which is not material to the Credit Parties' business or
operations and (y) "off the shelf" software obtained for less than $5,000
individually which is subject to shrink wrap licenses.

         (b) The Credit Parties own and have good title to, or are party to
enforceable License Agreements permitting the Credit Parties the use of, all
material items of Intellectual Property, free from Liens and restrictions that
adversely affect their businesses as now conducted and material additional
costs, which are necessary for the present and planned future conduct of their
businesses. Except as set forth in Schedule 4.22, and except for such matters as
in the aggregate are not reasonably likely to, and will not, result in a
Material Adverse Effect, (i) to the best knowledge of the Parent and the Issuer,
none of the present or contemplated products or operations of the Credit
Parties, or the use by the Credit Parties of any of such Intellectual Property,
infringes or otherwise violates, or will then infringe or otherwise violate, any
Intellectual Property owned by any other Person, and (ii) there is no pending
or, to the best knowledge of the Parent and the Issuer, threatened claim,
demand, litigation, investigation, arbitration or other proceeding against or
affecting any Credit Party contesting the right of any of them to manufacture,
distribute or sell any such product or to engage in any such operation, or to
use any of such Intellectual Property.

         (c) All registrations for Intellectual Property identified on Schedule
4.22 are valid and in force, and all applications to register any unregistered
Intellectual Property so identified are pending and in good standing, and are
all without challenge of any kind. The Intellectual Property owned by the Credit
Parties is valid and enforceable in all material respects. Each Credit Party has
the sole and exclusive right to bring actions




                                       49
<PAGE>   57

for infringement or unauthorized use of the Intellectual Property and software
that is listed on Schedule 4.22 owned by such Credit Party, as the case may be,
and there is no valid basis for any such action. Correct and complete copies of
registrations for all registered Intellectual Property identified on Schedule
4.22 (together with any subsequent correspondence with the United States
Copyright Office or the United States Patent and Trademark Office, as
applicable, or filings relating to the foregoing) have been delivered or made
available by the Credit Parties to the Purchasers or their counsel.

         Section 4.23 Use of Proceeds. The proceeds from the sale and issuance
of the Notes and Warrants on the Closing Date will be used by the Credit Parties
to refinance the Senior Subordinated Bridge Loan and to pay costs and expenses
of the Transactions.

         Section 4.24 Foreign Assets Control Regulations. None of the Credit
Parties nor, to the best knowledge of the Parent and the Issuer after due
inquiry, any Affiliate of any Credit Party, is, or will be after consummation of
the Transactions and application of the proceeds of the Notes, by reason of
being a "national" of a "designated foreign country" or a "specially designated
national" within the meaning of the Regulations of the Office of Foreign Assets
Control, United States Treasury Department (31 C.F.R., Subtitle B, Chapter V),
or for any other reason, in violation of, any United States Federal Statute or
Presidential Executive Order concerning trade or other relations with any
foreign country or any citizen or national thereof or the ownership or operation
of any Property.

         Section 4.25 Status under Certain Laws. No Credit Party is an
"investment company" or a "person directly or indirectly controlled by or acting
on behalf of an investment company" within the meaning of the Investment Company
Act of 1940, as amended, or a "holding company," or a "subsidiary company" of a
"holding company," or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company," within the meaning of the Public Utility
Holding Company Act of 1935, as amended. No Credit Party is subject to
regulation as a "common carrier" or "contract carrier" or any similar
classification by the Interstate Commerce Commission or under the laws of any
state, or is subject to regulation under any other federal, state or local
Statute which limits its ability to incur Indebtedness.

         Section 4.26 Ranking of Notes. The Indebtedness represented by the
Notes and the other Obligations under the Note Documents of each Credit Party
are intended to constitute senior subordinated Indebtedness, and accordingly is,
and shall be at all times while the Notes remain outstanding or the Purchasers
have any obligation to purchase Notes hereunder, (i) senior in right of payment
to, or pari passu with, all other unsecured Indebtedness (other than the
unsecured portion, if any, of the Senior Indebtedness), of such Credit Party, as
the case may be, respectively, and (ii) senior in right of payment to all other
Indebtedness of such Credit Party which, under the terms of the documents
pursuant to or in connection with which such Indebtedness was created or
incurred, is subordinated in right of payment to some or all of the other
Indebtedness (other than the Senior Indebtedness) of such Credit Party, as the
case may be.

         Section 4.27 Customers . Set forth in Schedule 4.27 is a list, as of
the Closing Date after giving effect to the Transactions, of the Credit Parties'
ten largest operating customers and clients, as measured by gross revenues of
the Credit Parties generated by such customers and clients, for the three years
ended as of December 31, 1997, 1998 and 1999. Except as disclosed on Schedule
4.27, as of the Closing Date, no significant customer or client (or group of
related customers or clients which in the aggregate is significant) of the
Credit Parties has given any of them notice or, to the knowledge of the Credit
Parties, has taken any other action which has given any Credit Party any reason
to believe that such customer or client (or group of customers or clients) will
materially reduce the amount of its purchases or adversely change the price or
terms to any Credit Party of such purchases. For such purposes, a customer or
client (or group of customers or clients) shall be deemed "significant" if such
customer or client (or group of related customers or clients) has accounted for
more than 5% of the total gross revenues of the Credit Parties (taken as a
whole) during the past fiscal year.

such representation or warranty specifically relate to an earlier date in which
case such representation or warranty shall be true and correct in all material

upon such representations and warranties with the same force and effect as if
they were incorporated in this Agreement and made to the Purchasers directly.

         (b) All aspects of the Transactions have been effected in all material
respects in accordance with terms of the Transaction Documents and applicable

Government Bodies required in order to consummate the Transactions in accordance
with the terms of the Transaction Documents and all applicable laws shall have
been obtained, given, filed or taken and are in full force and effect (or
effective judicial relief with respect thereto has been obtained). All
applicable waiting periods with respect thereto have or, prior to the time when
required, will have, expired without, in all such cases, any action being taken
by any competent authority which restrains, prevents or imposes material adverse
conditions upon the consummation




                                       51
<PAGE>   59

thereof, except as heretofore disclosed to the Purchasers in writing). This
Agreement and the other Transaction Documents constitute the only material
agreements relating to the Transactions to which any Credit Party is a party.

         (d) Except as set forth on Schedule 4.29, as of the Closing Date, no
Credit Party has any further obligations or liabilities to make any payments of
any kind to any Person pursuant to the Transaction Documents or relating to the
Transactions.

         Section 4.30 RICO. No Credit Party is engaged in or has engaged in any

the time of the acquisition thereof as a result of an Investment pursuant to
Section 9.7; provided that the restrictions applicable to the respective such
Joint Venture are not made worse, or more burdensome, from the perspective of
the




                                       52
<PAGE>   60

Parent and its Subsidiaries, than those as in effect immediately before giving

Second Step Merger, the Issuer caused an amendment to its Certificate of

               Section 4.34 Operating Company Status. Each of the Credit Parties

operating company"), as such terms are defined in 29 C.F.R. Section 2510.3-101,
and (ii) primarily engaged in the provision of executive office suites and
related office services and not the investment of capital. Each of the Credit
Parties employs a majority of its assets in the foregoing operating business,
incurs a majority of its expenses in furtherance thereof, and derives a majority
of its gross income from such activities. Each of the Credit Parties has not
merely passively assumed the risks from the ownership of its assets, but the

office service functions with respect to the foregoing operating business,
subject to supervision by such Credit Party, as to which supervision such Credit

promulgated thereunder.

Agreement shall be true on and as of the Closing Date with the same effect as if
such representations and warranties had been made on and as of the Closing Date
after giving effect to the Transactions contemplated hereby (except to the

all material respects on and as of such date). Each Credit Party shall have

Agreement on or prior to the Closing Date, and there shall exist no Default or
Event of Default on the Closing Date after giving effect to the Transactions

by such Purchaser's attorney duly authorized in writing, the Issuer will execute
and deliver in exchange therefor a new Note or Notes in such denominations as
may be requested by such Purchaser, of like tenor and in the same aggregate
unpaid principal amount as the aggregate unpaid principal amount of the Note or
Notes so surrendered. Any Note issued in exchange for any other Note or upon
transfer thereof shall carry the rights to unpaid interest and interest to
accrue which were carried by the Note so exchanged or transferred, and neither
gain nor loss of interest shall result from any such transfer or




                                       93

exchange. Any transfer tax or governmental charge relating to such transaction

and exclusive record and beneficial Purchaser and owner of such Note for the
purpose of receiving payment of the principal of, prepayment charge (if any) and
interest and other amounts on such Note and for all other purposes whatsoever,
whether or not such Note be overdue.

         Section 12. Lost, Stolen, Damaged and Destroyed Notes. At the request
of any Purchaser, the Issuer will issue and deliver at its expense, in
replacement of any Note or Notes issued by the Issuer lost, stolen, damaged or
destroyed, upon surrender thereof, if mutilated, a new Note or Notes in the same
aggregate unpaid principal amount, and otherwise of the same tenor, as the Note
or Notes so lost, stolen, damaged or destroyed, duly executed by the Issuer. The
Issuer may condition the replacement of a Note or Notes reported by the
Purchaser thereof as lost, stolen, damaged or destroyed, upon the receipt from
such Purchaser of an indemnity and/or security reasonably satisfactory to the
Issuer; provided that if such Purchaser shall be Chase, Capital Trust, Ares I,
Ares II, Blackstone Partners, or Blackstone Holdings, or a nominee thereof, such
Purchaser's unsecured agreement of indemnity shall be sufficient for purposes of
this Section.

         Section 13. Miscellaneous.

               Section 13.1 Amendment and Waiver

               (a) No amendment or waiver of any provision of this Agreement,
the Notes or any other Note Document, or any consent to any departure by the
Credit Parties therefrom, shall in any event be effective unless the same shall
be in writing and signed by the Required Purchasers, the Parent and the Issuer.
Any such waiver or consent shall be effective only in the specific instance and
for the purpose for which given. Neither any failure nor any delay on the part
of the Purchasers in exercising any right, power or privilege hereunder or under
the Notes or any of the Transaction Documents shall operate as a waiver thereof,
nor shall a single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. Except
as otherwise provided herein or in the Notes or any Note Document, no notice to
or demand on the Credit Parties or any other Person in any case shall entitle
such Person to any other or further notice or demand in the same, similar or
other circumstances.

               (b) Notwithstanding the provisions of subsection (a) of this
Section 13.1, without the specific prior written consent of all of the
Purchasers, no amendment, waiver or consent referred to in such subsection (a)
shall (i) reduce the principal of, or the rate of interest on, or the fees
payable with respect to, any of the Notes, (ii) extend the time for payment of
all or any portion of the principal of or interest on, or fees payable with
respect to, any of the Notes, (iii) reduce the percentage of the Notes required
with respect to any such amendment or to effectuate any such waiver or consent,
or modify the definitions herein of the term "Required Purchasers", or (iv)
modify any provision of this Section 13.1.

               (d) any attempt to enforce any remedies of any Purchaser against

         Section 13.3 Survival of Representations and Warranties. All
representations and warranties contained herein or made in writing by or on
behalf of any party to this Agreement or otherwise in connection herewith, shall
(i) survive the execution and delivery of this Agreement and the delivery of the
Notes and Warrants to the Purchasers and shall continue in effect until all of
the Obligations have been indefeasibly paid in full and no Notes are
outstanding, and thereafter as provided in Sections 13.2 and 13.6 with respect
to the obligations imposed thereunder, and (ii) be deemed to be material and to
have been relied upon by the Purchasers, regardless of any investigation made by
the Purchasers or on their behalf.

         Section 13.4 Successors and Assigns.

         (a) This Agreement shall be binding upon and inure to the benefit of
the Parent and the Issuer and the Purchasers, and their respective successors
and assigns; provided, however, that none of the Parent or the Issuer shall have
the right to assign its rights hereunder or any interest herein or to delegate
any of its duties hereunder without the prior written consent of the Purchasers.

         (b) Subject to the provisions of Section 13.4(c), any Purchaser (the
"Assignor") may at any time at its cost and expense sell or assign to any Person
(each an "Assignee") all or any part of its interests in the Notes, this
Agreement and the other Note Documents and in the obligations of the Credit
Parties hereunder and thereunder, and each such Assignee shall assume the
obligations of the Assignor hereunder and thereunder, to the extent provided in
such assignment, and to the extent of such assumption the Assignor shall be
released from its obligations hereunder and thereunder.




                                       96
<PAGE>   104

Upon execution and delivery of such an instrument, such Assignee shall be a
party to this Agreement and shall have the rights and obligations of a Purchaser
(including its rights under this Section 13.4(b)), to the extent of such
assignment, and the Assignor shall be released from its obligations hereunder to
a corresponding extent. Upon the consummation of any assignment by the Assignor
pursuant to this Section 13.4(b), the Assignor and the Issuer shall make
appropriate arrangements so that, if required, new Notes shall be issued to the
Assignor and the Assignee. The Assignor shall give the Issuer prior written
notice of the date that any such assignment shall become effective, which date
shall be no less than two Business Days after the date such notice is given.

         (c) Notwithstanding any other provision of this Agreement to the
contrary (other than Section 13.4(d)), no Purchaser shall transfer any Notes to
any Person (other than any Person who immediately prior to such transfer is (x)
an Affiliate of such Purchaser or a limited or general partner of any Purchaser
or (y) another Purchaser) unless (i) the aggregate principal amount of Notes
concurrently transferred to such Person (taken together with any concurrent
transfers of Notes by the transferor to the transferee) shall be not less than
the lesser of $5,000,000 and the entire remaining principal balance of the Notes
held by such transferor, (ii) such Person is an Eligible Transferee, (iii) such
Person is not a Company Competitor and (iv) so long as no Event of Default shall
have occurred and is continuing the prior written consent of the Issuer (which
shall not be unreasonably withheld or delayed) shall have been obtained.

         (d) Notwithstanding the foregoing Section 13.4(c), if the Notes are
publicly registered, no selling Purchaser shall be required to obtain the
consent of the Issuer and, subject to Section 13.4(b), the Notes shall be freely
transferable without restriction; provided that, without the prior written
consent of the Issuer (which shall not be unreasonably withheld or delayed), no
selling Purchaser shall transfer any Notes to a Company Competitor.

         Section 13.5 Notices. All notices hereunder shall be in writing and
shall be conclusively deemed to have been received and shall be effective (a) on
the day on which delivered if delivered personally or transmitted by telecopier,
(b) one Business Day after the date on which the same is delivered to a
nationally recognized overnight courier service, or (c) three Business Days
after being sent by registered or certified United States mail, return receipt
requested, and shall be addressed:

         Section 13.6 Indemnification. The Parent and the Issuer jointly and
severally, each hereby agrees to defend, indemnify, exonerate and hold harmless
each Purchaser and its affiliates and each of their respective officers,
partners, members, directors, stockholders, trustees, employees and agents
(herein collectively called the "Indemnitees") from and against any and all
liabilities, obligations, losses (excluding any loss in the value of the
Warrants or Warrant Stock), damages, claims, actions, suits, proceedings,
judgments, costs and expenses, including legal fees and other expenses incurred
in the investigation, defense, appeal and settlement of claims, actions, suits
and proceedings (herein collectively called the "Indemnified Liabilities"),
incurred by the Indemnitees or any of them as a result of, or arising out of or
relating to:

               (i) any action or failure to act by any Credit Party;

               (ii) any statements or omissions made in any disclosure or other
information or materials used in connection with the Transactions, including any
sale, syndication or other transfer of securities of any Credit Party;

               (iii) the action or failure to act by an Indemnitee with the
consent or in reliance on any action or failure to act of any Credit Party;

               (iv) the execution, delivery, performance or enforcement of this
Agreement, the other Transaction Documents or any other instrument or document
contemplated hereby or thereby by any of the Indemnitees, or the Transactions or
any act, event or transaction related or attendant thereto or contemplated
hereby or thereby, or any action or inaction by any Indemnitee under or in
connection therewith; or

               (v) any Environmental Matter, any Environmental Law or the actual
or alleged existence or release of any Hazardous Material

except with respect to any Indemnitee for any such Indemnified Liabilities that
are finally judicially determined to have resulted from such Indemnitee's gross
negligence or willful misconduct, and if and to the extent that the foregoing
undertaking may be unenforceable for any reason, the Parent and the Issuer
jointly and severally each hereby agrees to make





                                      100
<PAGE>   108

the maximum contribution to the payment and satisfaction of each of the
Indemnified Liabilities which is permissible under applicable law. The
obligations of the Parent and the Issuer under this Section 13.6 shall be in
addition to any liability that they may otherwise have and shall survive the
payment or prepayment in full or transfer of any Note or Warrant and the
enforcement of any provision hereof or thereof.

               Section 13.7 Public Announcements. The Parent and the Issuer
agree that they will not issue any press release or make any other public
announcement, statement or filing with regard to this Agreement, the Notes, the
Warrants or the other Transaction Documents or the Transactions without the
prior approval of the Required Purchasers, which approval shall not be
unreasonably withheld and shall in no event be withheld in any case where such
press release, public announcement, statement or filing is required by
applicable law (including applicable rules and regulations of the SEC).

               Section 13.8 No Fiduciary Relationship. The Purchasers shall not,
by reason of their purchase or holding of Notes or Warrants pursuant to this
Agreement, be deemed to have any fiduciary or other special relationship with
the Credit Parties. No provision of this Agreement, the Notes, the Warrants, the
other Note Documents or any of the other documents executed and delivered in
connection herewith shall be construed to create a fiduciary duty on the part of
the Purchasers or any trustee or agent therefor in favor of the Credit Parties,
any of their Subsidiaries or Affiliates, or their respective directors,
officers, employees, agents, Stockholders or creditors.

               Section 13.9 Integration and Severability. This Agreement
(including the schedules and exhibits thereto), the Notes, the Warrants, the
other Note Documents and the other documents executed pursuant to this Agreement
