            2. GUARANTY.

                  (a) Each Guarantor hereby absolutely, unconditionally and
irrevocably guarantees the punctual payment when due, whether at scheduled
maturity or on any date of a required prepayment or by acceleration, demand or
otherwise, of all obligations of the Company now or hereafter existing under or
in respect of the Operative Documents (including, without limitation, any
extensions, modifications, substitutions, amendments or renewals of any or all
of the foregoing obligations), whether direct or indirect, absolute or
contingent, and whether for principal, interest, premiums, fees, indemnities,
contract causes of action, costs, expenses or otherwise (such obligations being
the "Guaranteed Obligations"), and agrees to pay any and all reasonable expenses
(including, without limitation, reasonable fees and expenses of counsel)
reasonably incurred by the Agent or any Investor in enforcing any rights under
or in respect of any Operative Document. Without limiting the generality of the
foregoing, each Guarantor's liability shall extend to all amounts that
constitute part of the Guaranteed Obligations and would be owed by the Company
to any Investor under or in respect of the Operative Documents but for the fact
that they are unenforceable or not allowable due to the existence of a
bankruptcy, reorganization or similar proceeding involving the Company.

                  (b) Each Guarantor, and by its acceptance of this Guaranty,
the Agent and each other Investor, hereby confirms that it is the intention of
all such Persons that the provisions of this Guaranty and the obligations of
each Guarantor hereunder not constitute a fraudulent transfer or conveyance for
purposes of Bankruptcy Law (as hereinafter defined), the Uniform Fraudulent
Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign,
federal or state law to the extent applicable to this Guaranty and the
obligations of each Guarantor hereunder. To effectuate the foregoing intention,
the Agent, the other Investors and the Guarantors hereby irrevocably agree that
the obligations of each Guarantor under this Guaranty at any time shall be
limited to the maximum amount as will result in the obligations of such
Guarantor under this Guaranty not constituting a fraudulent transfer or
conveyance. For purposes hereof, "Bankruptcy Law" means any proceeding of the
type referred to Title 11, U.S. Code, or any similar foreign, federal or state
law for the relief of debtors.

                  (c) Each Guarantor hereby unconditionally and irrevocably
agrees that in the event any payment shall be required to be made to any
Investor under this Guaranty or any other guaranty, such Guarantor will
contribute, to the maximum extent permitted by law, such amounts to each other
Guarantor so as to maximize the aggregate amount paid to the Investors under or
in respect of the Operative Documents.

                  (d) Each Guarantor guarantees that the Guaranteed Obligations
will be paid strictly in accordance with the terms of the Operative Documents,
regardless of any law, regulation or order now or hereafter in effect in any
jurisdiction affecting any of such terms or the rights of any Investor with
respect thereto. The obligations of each Guarantor under or in respect of this
Guaranty are independent of the Guaranteed Obligations or any other obligations
of any other Guarantor under or in respect of the Operative Documents, and a
separate action or actions may be brought and prosecuted against each Guarantor
to enforce this Guaranty, irrespective of whether any action is brought against
the Company or any other Guarantor or whether the Company or any other Guarantor
is joined in any such action or actions. The liability of each Guarantor under
this Guaranty shall be irrevocable, absolute and unconditional irrespective of,
and each Guarantor hereby irrevocably waives any defenses it may now have or
hereafter acquire in any way relating to, any or all of the following:
<PAGE>
                                       10

                        (i) any lack of validity or enforceability of any
                  Operative Document, the Purchase Agreement or any agreement or
                  instrument relating thereto;

                        (ii) any change in the time, manner or place of payment
                  of, or in any other term of, all or any of the Guaranteed
                  Obligations or any other obligations of any other Guarantor
                  under or in respect of the Operative Documents or any other
                  amendment or waiver of or any consent to departure from any
                  Operative Document or the Purchase Agreement including,
                  without limitation, any increase in the Guaranteed Obligations
                  resulting from the extension of additional credit to the
                  Company or any of its Subsidiaries or otherwise;

                        (iii) any taking, exchange, release or non-perfection of
                  any Collateral or any other collateral, or any taking, release
                  or amendment or waiver of, or consent to departure from, any
                  other guaranty, for all or any of the Guaranteed Obligations;

                        (iv) any manner of application of Collateral or any
                  other collateral, or proceeds thereof, to all or any of the
                  Guaranteed Obligations, or any manner of sale or other
                  disposition of any Collateral or any other collateral for all
                  or any of the Guaranteed Obligations or any other obligations
                  of the Company under or in respect of the Operative Documents
                  or any other assets of the Company or any of its Subsidiaries;

                        (v) any change, restructuring or termination of the
                  corporate structure or existence of the Company or any of its
                  Subsidiaries;

                        (vi) any failure of any Investor to disclose to any
                  Guarantor any information relating to the business, condition
                  (financial or otherwise), operations, performance, properties
                  or prospects of the Company now or hereafter known to such
                  Investor (each Guarantor waiving any duty on the part of the
                  Investors to disclose such information);

                        (vii) the failure of any other Person to execute or
                  deliver this Agreement or any other guaranty or agreement or
                  the release or reduction of liability of any Guarantor or
                  other guarantor or surety with respect to the Guaranteed
                  Obligations; or

                        (viii) any other circumstance (including, without
                  limitation, any statute of limitations) or any existence of or
                  reliance on any representation by any Investor that might
                  otherwise constitute a defense available to, or a discharge
                  of, any Guarantor or any other guarantor or surety.

This Guaranty shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Guaranteed Obligations is rescinded
or must otherwise be returned by any Investor or any other Person upon the
insolvency, bankruptcy or reorganization of the Company or any other Guarantor
or otherwise, all as though such payment had not been made.

            3. CREATION OF SECURITY INTEREST.

                  (a) Each Grantor does hereby grant and pledge to the Agent,
for the ratable benefit of the Investors and the Agent, a security interest in
and to, all right, title and interest of such Grantor in and to all presently
existing and hereafter acquired Collateral. The security interest hereunder
secures the payment and performance of all obligations of each Grantor now or
hereafter existing under or in respect of the Operative Documents. The security
interest and pledge created by this Section 3 shall continue in effect so long
as such obligations remain outstanding.
<PAGE>
                                       11

                  (b) Each Grantor agrees that it will not sell, assign, or
otherwise dispose of any of the Collateral other than (i) cash expenditures not
otherwise in violation of the Operative Documents, (ii) sales and leases of
customer premises equipment in the ordinary course of business, (iii) sales of
inventory in the ordinary course of business and (iv) sales of worn-out,
obsolete or excess equipment provided that such sales are made on an arms length
basis. Upon the consummation of such sales or other dispositions, in the manner
contemplated by this Section 3(b), the security interest granted herein with
respect to such Collateral shall be deemed released.

            4. DELIVERY OF PLEDGED COLLATERAL.

                  (a) Each Certificate shall, on (i) the Closing Date (with
respect to Certificates delivered on such date) and (ii) the day on which such
Certificate shall be received or acquired by a Grantor (with respect to any
Certificate received or acquired after the Closing Date), be delivered to and
held by or on behalf of the Agent, and shall be in suitable form for transfer by
delivery, or shall be accompanied by duly executed undated endorsements,
instruments of transfer or assignment in blank, all in form and substance
reasonably satisfactory to the Agent.

                  (b) With respect to each uncertificated Limited Liability
Company Interest and each uncertificated Partnership Interest, on (i) the
Closing Date (with respect such Limited Liability Company Interests and such
Partnership Interests existing on such date) and (ii) the day on which any such
Limited Liability Company Interest and any such Partnership Interest shall be
acquired by a Grantor (with respect to such Limited Liability Company Interests
and such Partnership Interests acquired after the Closing Date), a notice in the
form set forth in Exhibit A-1 attached hereto (the "Pledge Notice") shall be
appropriately completed and delivered to each Pledged Entity and each Pledged
Partnership Entity, notifying each Pledged Entity and each Pledged Partnership
Entity of the existence of this Agreement, a certified copy of this Agreement
shall be delivered by the Grantor to the relevant Pledged Entity and relevant
Pledged Partnership Entity, and such Grantor shall have received and delivered
to the Agent a copy of such Pledge Notice, along with an acknowledgment in the
form set forth in Exhibit A-2 attached hereto (the "Issuer Acknowledgment"),
duly executed by the relevant Pledged Entity.

                  (c) The Agent shall have the right, during the existence of an
Event of Default, without notice to any of the Grantors, in connection with a
commercially reasonable foreclosure sale, to transfer to, or to direct the
applicable Grantor or any nominee of such Grantor to register or cause to be
registered in the name of, the Agent or any of its nominees any or all of the
Pledged Securities, Pledged Partnership Interests or Pledged Limited Liability
Company Interests. In addition, the Agent, in furtherance of any action
referenced in the previous sentence, shall have the right at any time to
exchange certificates or instruments representing or evidencing Pledged
Securities for certificates or instruments of smaller or larger denominations.

            5. APPOINTMENT OF THE AGENT.

                  (a) Authorization and Action. Each Investor hereby appoints
and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers and discretion under this Agreement and the other Operative
Documents as are delegated to the Agent by the terms hereof and thereof,
together with such powers and discretion as are reasonably incidental thereto
and the Agent hereby accepts such appointment. As to any matters not expressly
provided for by the Operative Documents, the Agent shall not be required to
exercise any discretion or take any action, but shall be required to act or to
refrain from acting (and shall be fully protected in so acting or refraining
from acting) upon the instructions of the Majority Investors, and such
instructions shall be binding upon all Investors; provided, however, that the
Agent shall not be required to take any action that exposes the Agent to
personal liability or that is contrary to this Agreement, the other Operative
Documents, the Purchase
<PAGE>
                                       12

Agreement or applicable law. The Agent agrees to give to each Investor prompt
notice of each notice given to it by any Grantor pursuant to the terms of the
Operative Documents and the Purchase Agreement.

                  (b) Agent's Reliance, Etc. Neither the Agent nor any of its
respective directors, officers, agents or employees shall be liable for any
action taken or omitted to be taken by it or them under or in connection with
the Operative Documents, except for its or their own gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, the Agent:
(i) may consult with legal counsel (including counsel for any Grantor),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts; (ii) makes
no warranty or representation to any Investor and shall not be responsible to
any Investor for any statements, warranties or representations (whether written
or oral) made in or in connection with the Operative Documents or the Purchase
Agreement; (iii) shall not have any duty to ascertain or to inquire as to the
performance or observance of any of the terms, covenants or conditions of any
Operative Document on the part of any Grantor or to inspect the property
(including the books and records) of any Grantor; (iv) shall not be responsible
to any Grantor for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of, or the perfection or priority of any lien
or security interest created or purported to be created under or in connection
with, any Operative Document, the Purchase Agreement or any other instrument or
document furnished pursuant thereto; and (v) shall incur no liability under or
in respect of any Operative Document or the Purchase Agreement by acting upon
any notice, consent, certificate or other instrument or writing (which may be by
telegram, telecopy or telex) believed by it to be genuine and signed or sent by
the proper party or parties.

                  (c) Deutsche Bank Trust Company Americas and Affiliates. With
respect to the Note issued to it, Deutsche Bank Trust Company Americas shall
have the same rights and powers under the Operative Documents as any other
Investor and may exercise the same as though it were not the Agent; and the term
"Investors" shall, unless otherwise expressly indicated, include Deutsche Bank
Trust Company Americas in its individual capacity. Deutsche Bank Trust Company
Americas and its affiliates may accept deposits from, lend money to, act as
trustee under indentures of, accept investment banking engagements from and
generally engage in any kind of business with, any Grantor, any of its
Subsidiaries and any Person that may do business with or own securities of any
Grantor or any such Subsidiary, all as if Deutsche Bank Trust Company Americas
were not the Agent and without any duty to account therefor to the Investors.

                  (d) Investors Credit Decision. Each Investor acknowledges that
it has, independently and without reliance upon the Agent or any other Investor
and based on the financial statements referred to in Section 2 of the Purchase
Agreement and such other documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into the Operative Documents
and the Purchase Agreement. Each Investor also acknowledges that it will,
independently and without reliance upon the Agent or any other Investor and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under the Operative Documents and the Purchase Agreement.

                  (e) Successor Agents. The Agent may resign at any time by
giving written notice thereof to the Investors and the Grantors. Upon any such
resignation, the Majority Investors shall have the right to appoint a successor
Agent. If no successor Agent shall have been so appointed by the Majority
Investors, and shall have accepted such appointment, within 30 days after the
retiring Agent's giving of notice of resignation, then the retiring Agent may,
on behalf of the Investors, appoint a successor Agent, which shall be a
commercial bank organized under the laws of the United States or of any State
thereof and having a combined capital and surplus of at least $250,000,000. Upon
the acceptance of any appointment as the Agent hereunder by a successor Agent
and, upon the execution and
<PAGE>
                                       13

filing or recording of such financing statements, or amendments thereto, and
such other instruments or notices, as may be necessary or desirable, or as the
Majority Investors may request, in order to continue the perfection of the Liens
granted or purported to be granted by this Agreement and the other Operative
Documents, such successor Agent shall succeed to and become vested with all the
rights, powers, discretion, privileges and duties of the retiring Agent, and the
retiring Agent shall be discharged from its duties and obligations under the
Operative Documents. If within 45 days after written notice is given of the
retiring Agent's resignation under this Section 5(e) no successor Agent shall
have been appointed and shall have accepted such appointment, then on such 45th
day (a) the retiring Agent's resignation shall become effective, (b) the
retiring Agent shall thereupon be discharged from its duties and obligations
under the Operative Documents and (c) the Majority Investors shall thereafter
perform all duties of the retiring Agent under the Operative Documents until
such time, if any, as the Majority Investors appoint a successor Agent as
provided above. After any retiring Agent's resignation hereunder as the Agent
shall have become effective, the provisions of this Section 5(e) shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
the Agent under this Agreement.

                  (f) Agent's Rights Regarding Collateral. At any time and from
time to time, the Agent may, to the extent necessary or desirable to protect the
security hereunder, but the Agent shall not be obligated to: (a) (whether or not
an Event of Default has occurred) itself or through its representatives, at its
own expense (which shall be payable by the Grantors under Section 20, upon
reasonable prior notice and at such reasonable times during usual business
hours, visit and inspect any of the Grantors' properties and examine and make
abstracts from any of its books and records at any reasonable time and as often
as may reasonably be desired and discuss the business, operations, properties
and financial and other condition of any of the Grantors with officers of such
Grantors and with their accountants or (b) if an Event of Default has occurred
and is continuing, at the expense of the Grantors, perform any obligation of any
of the Grantors under this Agreement. At any time and from time to time after an
Event of Default has occurred and is continuing, at the expense of the Grantors,
the Agent may, to the extent necessary or desirable to protect the security
hereunder, but the Agent shall not be obligated to: (i) notify obligors of the
Collateral that the Collateral has been pledged as security to the Agent; (ii)
request from obligors of the Collateral, in the name of the applicable Grantor
or in the name of the Agent, information concerning the Collateral and the
amounts owing thereon; and (iii) direct obligors under the contracts included in
the Collateral to direct their performance to the Agent. Each Grantor shall keep
proper books and records and accounts in which full, true and correct entries in
conformity with GAAP and all applicable laws (including, without limitation, all
applicable regulations, rules and orders) shall be made of all material dealings
and transactions pertaining to the Collateral owned by it. The Agent shall at
all reasonable times on reasonable prior notice have full access to and the
right to audit any and all of Grantors' books and records pertaining to the
Collateral, and to confirm and verify the value of the Collateral. The Agent
shall not be under any duty or obligation whatsoever to take any action to
preserve any rights of or against any prior or other parties in connection with
the Collateral, to exercise any voting rights or managerial rights with respect
to any Collateral or to make or give any presentments for payment, demands for
performance, notices of non-performance, protests, notices of protest, notices
of dishonor or notices of any other nature whatsoever in connection with the
Collateral or the Notes. The Agent shall not be under any duty or obligation
whatsoever to take any action to protect or preserve the Collateral or any
rights of the Grantors therein, or to make collections or enforce payment
thereon, or to participate in any foreclosure or other proceeding in connection
therewith. Nothing contained herein or in any consent shall constitute an
assumption by the Agent of any of the Grantors' obligations under the contracts
assigned hereunder unless the Agent shall have given written notice to the
counterpart to such assigned contract of the Agent's intention to assume such
contract. Each Grantor shall continue to be liable for performance of its
obligations under such contracts.

                  (g) Possession of Collateral by the Agent. All the Collateral
now, heretofore or hereafter delivered to the Agent shall be held by the Agent
in its possession, custody and control. During
<PAGE>
                                       14

the existence of an Event of Default, whenever any of the Collateral is in
Agent's possession, custody or control, the Agent may use, operate and consume
the Collateral, whether for the purpose of preserving and/or protecting the
Collateral, or for the purpose of performing any of the Grantors' obligations
with respect thereto, or otherwise so long as consistent with the Operative
Documents or transactions contemplated thereby. The Agent may at any time
deliver or redeliver the Collateral or any part thereof to the Grantors, and the
receipt of any of the same by the Grantors shall be complete and full
acquittance for the Collateral so delivered, and the Agent thereafter shall be
discharged from any liability or responsibility arising after such delivery to
the Grantors. The Agent shall have no liability for any loss of or damage to any
Collateral not in the Agent's possession, and in no event shall the Agent have
liability for any diminution in value of Collateral occasioned by economic or
market conditions or events. The Agent shall be deemed to have exercised
reasonable care in the custody and preservation of any Collateral in its
possession, if such Collateral is accorded treatment substantially equal to that
which it accords its own property.

                  (h) Agent Appointed Attorney-in-Fact. To the full extent
permitted by applicable law, each Grantor hereby irrevocably appoints the Agent
as such Grantor's attorney-in-fact, with full authority in the place and stead
of such Grantor, and in the name of such Grantor, or otherwise, from time to
time, in the Agent's sole and absolute discretion to do any of the following
acts or things during the existence of an Event of Default: (a) to do all acts
and things and to execute all documents necessary or advisable to perfect and
continue the perfection of the security interests created by this Agreement and
to preserve, maintain and protect the Collateral, including, without limitation,
to obtain and adjust insurance required to be paid to the Agent pursuant to
Section 18; (b) to do any and every act that such Grantor is obligated to do
under this Agreement, including, without limitation, to ask for, demand,
collect, sue for, recover, compromise, receive and give acquittance and receipts
for moneys due and to become due under or in respect of any of the Collateral;
(c) to prepare, sign, file and record, in such Grantor's name, any financing
statement covering the Collateral; (d) to endorse and transfer the Collateral
upon foreclosure by the Agent; (e) to file any claims or take any action or
institute any proceedings that the Agent may deem necessary or desirable for the
collection of any of the Collateral or the protection or enforcement of any of
the rights of the Agent with respect to any of the Collateral; and (f) to
receive, indorse, and collect any draft or other instruments, documents and
chattel paper, in connection with any of the foregoing; provided, however, that
the Agent shall be under no obligation whatsoever to take any of the foregoing
actions, and the Agent shall have no liability or responsibility for any act or
omission (other than the Agent's own gross negligence or willful misconduct)
taken with respect thereto.

            6. PAYMENTS AND COMPUTATIONS.

                  (a) Each payment or prepayment of principal or interest on the
Notes shall be allocated pro rata among the Investors in proportion, as nearly
as practicable, to the respective unpaid principal amounts thereof.

                  (b) The Company will not directly or indirectly pay or cause
to be paid any remuneration, whether by way of supplemental or additional
interest, fee or otherwise, or grant any security, to any Investor as
consideration for or as an inducement to the entering into by any Investor of
any waiver of amendment of any of the terms and provisions hereof unless such
remuneration is concurrently paid, or security is concurrently granted, on the
same terms, ratably to all Investors then outstanding even if such Investor did
not consent to such waiver or amendment, so long as such waiver or amendment was
consented to by the requisite Investors.

            7. SHARING OF PAYMENTS, ETC. If any Investor shall obtain at any
time any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise), on account of the obligations to such Investor
under and in respect of the Notes at such time in excess of its ratable share of
<PAGE>
                                       15

payments on account of the obligations to all Investors under and in respect of
the Notes at such time obtained by all the Investors at such time, such Investor
shall forthwith purchase from the other Investors such interests or
participating interests in the obligations due and payable or owing to them, as
the case may be, as shall be necessary to cause such purchasing Investor to
share the excess payment ratably with each of them; provided, however, that if
all or any portion of such excess payment is thereafter recovered from such
purchasing Investor, such purchase from each other Investor shall be rescinded
and such other Investor shall repay to the purchasing Investor the purchase
price to the extent of such Investor's ratable share of such recovery together
with an amount equal to such Investor's ratable share of any interest or other
amount paid or payable by the purchasing Investor in respect of the total amount
so recovered. The Company agrees that any Investor so purchasing an interest or
participating interest from another Investor pursuant to this Section 7 may, to
the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such interest or participating
interest, as the case may be, as fully as if such Investor were the direct
creditor of the Company in the amount of such interest or participating
interest, as the case may be.

            8. FURTHER ASSURANCES.

                  (a) At any time and from time to time at the reasonable
written request of the Agent, each Grantor shall promptly execute and deliver to
the Agent, at such Grantor's expense, all such financing statements and other
instruments, certificates and documents (including account control agreements)
in form and substance reasonably satisfactory to the Agent, and perform all such
other acts as shall be necessary or reasonably desirable to fully perfect or
protect or maintain, when filed, recorded, delivered or performed, the Agent's
security interests granted pursuant to this Agreement or to enable the Agent to
exercise and enforce its rights and remedies hereunder with respect to any
Collateral. Without limiting the generality of the foregoing, each Grantor
shall: (i) at the request of the Agent, mark conspicuously each document
included in the Inventory and each chattel paper relating to the Receivables,
each Related Contract, and all instruments and other documents and each of its
records pertaining to the Collateral with a legend, in form and substance
satisfactory to the Agent, indicating that such document, chattel paper, Related
Contract, instrument or Collateral is subject to the security interest granted
hereby, (ii) at the request of the Agent, if any account or contract or other
writing relating thereto shall be evidenced by a promissory note or other
instrument, deliver and pledge to the Agent hereunder, such note or other
instrument duly endorsed and accompanied by duly executed undated instruments of

                  (b) Each Grantor hereby authorizes the Agent to file one or
more financing or continuation statements, and amendments thereto (including,
without limitation, one or more financing statements indicating that such
financing statement covers all assets or all property (or words of similar
effect) of such Grantor), relative to the Collateral (or any part thereof), in
each case without the signature of such Grantor (and regardless of whether any
particular asset described in such financing statements falls within the scope
of the UCC or the granting clause of this Agreement) where permitted by law. A
carbon, photographic or other reproduction of this Agreement or any financing
statement covering the Collateral or any part thereof shall be sufficient as a
financing statement where permitted by law.

                  (c) With respect to any Collateral consisting of securities,
instruments, partnership or joint venture interests, limited liability company
interests, or the like, each Grantor hereby consents and agrees that, during the
existence of an Event of Default, the issuers of, or obligors on, any such
Collateral, or any registrar or transfer agent or trustee for any such
Collateral, shall be entitled to accept the provisions of this Agreement as
conclusive evidence of the right of the Agent to effect any transfer or exercise
any right hereunder or with respect to any such Collateral subject to the terms
hereof, notwithstanding any other notice or direction to the contrary heretofore
or hereafter given by any Grantor or any other Person to such issuers or such
obligors or to any such registrar or transfer agent or trustee.

                  (d) At any time and from time to time, the Agent shall be
entitled to file and/or record any instruments and documents held by it and any
or all such further documents and instruments, relative to the Collateral or any
part thereof in each instance, and to take all such other actions as the Agent
may reasonably deem appropriate or necessary to perfect and to maintain
perfected the security interests granted herein.

            9. VOTING RIGHTS; DIVIDENDS; ETC.  So long as no Event of Default
shall have occurred and be continuing:

                  (a) Voting Rights. Each Grantor shall be entitled to exercise
any and all voting and other consensual rights pertaining to its Pledged
Securities, its Pledged Partnership Interests and its Pledged Limited Liability
Company Interests, or any part thereof, for any purpose not inconsistent with
the terms of this Agreement, or the other Operative Documents; provided,
however, that each Grantor shall not exercise, or shall refrain from exercising,
any such right if it would result in an Event of Default.

                  (b) Dividend and Distribution Rights. Subject to the terms of
the Purchase Agreement, each Grantor shall be entitled to receive and to retain
and use any and all dividends, interest or distributions paid in respect of its
Pledged Securities, its Pledged Partnership Interests or its Pledged Limited
Liability Company Interests; provided, however, that any and all:

                        (i) non-cash dividends or distributions in the form of
                  capital stock, certificated limited liability company
                  interests, instruments or other property received, receivable
                  or otherwise distributed in respect of, or in exchange for,
                  any Pledged Securities, Pledged Partnership Interests, Pledged
                  Limited Liability Company Interests,

                        (ii) dividends and other distributions paid or payable
                  in cash in respect of any Pledged Securities, Pledged
                  Partnership Interests or Pledged Limited Liability Company
                  Interests in connection with a partial or total liquidation or
                  dissolution or in connection with a reduction of capital,

                        (iii) cash paid, payable or otherwise distributed in
                  redemption of, or in exchange for, any Pledged Securities,

<PAGE>
                                       17

shall, except as otherwise provided for in the Operative Documents, be forthwith
delivered to the Agent, in the case of (i) above, to be held as Collateral and
shall, if received by such Grantor, be received in trust for the benefit of the
Agent, be segregated from the other property of such Grantor and forthwith be
delivered to the Agent as Collateral in the same form as so received (with any
necessary endorsements), and in the case of (ii) and (iii) above, to be held as
Collateral.

            10. RIGHTS AS TO PLEDGED COLLATERAL DURING EVENT OF DEFAULT. When an
Event of Default has occurred and is continuing:

                  (a) Voting, Dividend and Distribution Rights. Upon notice from
the Agent to the Grantors, all rights of each Grantor to exercise the voting and
other consensual rights which it would otherwise be entitled to exercise
pursuant to Section 9(a) above, and to receive the dividends and distributions
which it would otherwise be authorized to receive and retain pursuant to Section
9(b) above, shall cease, and all such rights shall thereupon become vested in
the Agent who shall thereupon have the sole right to exercise such voting and
other consensual rights and to receive and to hold as Pledged Collateral such
dividends and distributions during the continuance of such Event of Default.

                  (b) Dividends and Distributions Held in Trust. All dividends
and other distributions which are received by any Grantor contrary to the
provisions of Section 10(a) of this Agreement shall be received in trust for the
benefit of the Agent, shall be segregated from other funds of such Grantor and
forthwith shall be paid over to the Agent as Collateral in the same form as so
received (with any necessary endorsements).

            11. IRREVOCABLE PROXY. Each Grantor hereby revokes all previous
proxies with regard to its Pledged Securities, its Pledged Partnership Interests
and its Pledged Limited Liability Company Interests and, appoints the Agent as
its respective proxyholder to (a) attend and vote at any and all meetings of the
shareholders of the corporation(s) which issued the Pledged Securities, and any
adjournments thereof, held on or after the date of the giving of this proxy and
prior to the termination of this proxy and to execute any and all written
consents of shareholders of such corporation(s) executed on or after the date of
the giving of this proxy and prior to the termination of this proxy, with the
same effect as if such Grantor had personally attended the meetings or had
personally voted its shares or had personally signed the written consents,
waivers or ratification, and (b) to attend and vote at any and all meetings of
the members of the Pledged Entities or partners of the Pledged Partnership
Entities (whether or not such Pledged Limited Liability Company Interests or
Pledged Partnership Interests are transferred into the name of the Agent), and
any adjournments thereof, held on or after the date of the giving of this proxy
and to execute any and all written consents, waivers and ratifications of the
Pledged Entities or Pledged Partnership Entities executed on or after the date
of the giving of this proxy and prior to the termination of this proxy with the
same effect as if such Grantor had personally attended the meetings or had
personally voted on their respective Limited Liability Company Interests or
Partnership Interests or had personally signed the consents, waivers or
ratifications; provided, however, that the Agent as proxyholder shall have
rights hereunder only during the existence of an Event of Default. Each Grantor
hereby authorizes the Agent to substitute another Person (which Person shall be
a successor to the rights of the Agent hereunder, a nominee appointed by the
Agent to serve as proxyholder, or otherwise as approved by such Grantor in
writing, such approval not to be unreasonably withheld) as the proxyholder and,
during the existence of any Event of Default, hereby authorizes and directs the
proxyholder to file this proxy and the substitution instrument with the
secretary of the appropriate corporation. This proxy is coupled with an interest
and is irrevocable until such time as all outstanding principal and interest on
the Notes have been indefeasibly paid in full.

            12. THE GRANTORS' REPRESENTATIONS AND WARRANTIES. Each Grantor
represents and warrants as follows:

of funds in the Deposit Accounts without the further consent of the Grantor and

the Agent (the "Account Control Agreement").

                  (e) No consent of any Person, including, without limitation,

Schedule 3-C attached hereto, and there is no other class of shares issued and
outstanding of the respective issuers thereof except as set forth on Schedule

as may be required in connection with any disposition of Collateral consisting
of securities by laws affecting the offering and sale of securities generally or
(C) the perfection or maintenance of the security interest created hereunder

            13. COPYRIGHTS.

                  (a) Royalties. Each Grantor hereby agrees that the use by the
Agent of the Copyrights as authorized hereunder in connection with the Agent's
exercise of its rights and remedies hereunder shall be without any liability for
royalties or other related charges from the Agent to Grantors.

                  (b) Restrictions on Future Agreements. Subject to the terms
hereof and of the Purchase Agreement, each Grantor shall be permitted to manage,
license and administer its Copyrights in such manner as such Grantor in its
reasonable business judgment deems desirable, provided, however, that such
Grantor will not, without the Agent's prior written consent, such consent not to
be unreasonably withheld or delayed, (i) enter into any copyright license
agreements except license agreements entered into in the ordinary course of its
business consistent with past practices and containing such additional
provisions to protect the Agent's interest hereunder as the Agent may from time
to time reasonably request or (ii) take any action, or permit any action to be
taken by others, including, without limitation, licensees, or fail to take any
action, which would customarily be taken by a Person in the same business and in
similar circumstances as such Grantor, which could in any respect reasonably be
expected to have a Material Adverse Effect.

                  (c) Duties of Grantors. Each Grantor shall have the duty to:

                      In accordance with its standard commercial practices, (i)
prosecute diligently any copyright application included in the Copyrights, (ii)
place notices of copyright on all copyrightable property produced or owned by
such Grantor embodying the Copyrights and use diligent reasonable efforts to

preserve and maintain all of Grantor's rights in the Copyrights that are or
shall be necessary in the operation of Grantor's business, including, without

Copyrights and diligently monitoring unauthorized use thereof. Any expenses
incurred in connection with the foregoing
<PAGE>
                                       20

shall be borne by Grantors. The Agent shall have no duty with respect to the
Copyrights other than to act lawfully and without gross negligence or willful
misconduct. Without limiting the generality of the foregoing, the Agent shall
not be under any obligation to take any steps necessary to preserve rights in
the Copyrights against any other parties, but the Agent may do so at its option
upon the occurrence and during the continuance of an Event of Default, and all
reasonable expenses incurred in connection therewith shall be for the sole
account of Grantors.

            14. PATENTS AND MARKS.

                  (a) Royalties. Each Grantor hereby agrees that any rights
granted hereunder to the Agent with respect to Patents and Marks shall be
applicable to all jurisdictions in which such Grantor has the right to use such
Patents and Marks, from time to time, and without any liability for royalties or
other related charges from the Agent to Grantors.

                  (b) Restrictions on Future Agreements. Each Grantor will not,
except in accordance with its standard commercial practices, abandon any Patent
or Mark in which such Grantor now owns or hereafter acquires any rights or
interests if such abandonment could reasonably be expected to have a Material
Adverse Effect or enter into any agreement, including, without limitation, any
license agreement, which is inconsistent with such Grantor's obligations under
this Agreement, if such actions could reasonably be expected to have a Material
Adverse Effect. Each Grantor further agrees that it will not take any action, or
permit any action to be taken by others subject to its control, including
licensees, or fail to take any action which would customarily be taken by a
Person in the same business and in similar circumstances as such Grantor, which
could reasonably be expected to have a Material Adverse Effect.

                  (c) Duties of Grantors. In accordance with its standard
commercial practices, each Grantor shall have the duty to (i) prosecute
diligently any patent application or trademark application pending as of the
date hereof or thereafter until the Notes shall have been indefeasibly paid in
full, (ii) file and prosecute opposition and cancellation proceedings if the
failure to do so could reasonably be expected to have a Material Adverse Effect
and (iii) take all reasonable action necessary in such Grantor's reasonable
business judgment consistent with past practices to preserve and maintain all
rights in patent applications of the Patents and in applications for
registrations of the Marks unless the failure so to do could not reasonably be
expected to have a Material Adverse Effect. Any expenses incurred in connection
with the foregoing applications shall be borne by Grantors. Each Grantor shall
not abandon any right to file a Patent application or Mark application except in
accordance with its standard commercial practices if such abandonment could
reasonably be expected to have a Material Adverse Effect. Each Grantor shall
give proper statutory notice in connection with its use of each of the Marks to
the extent necessary for the protection of each of the Marks. Grantors shall
notify the Agent of any suits it commences to enforce the Patents and Marks and
shall provide the Agent with copies of any documents reasonably requested by the
Agent relating to such suits.

            15. GRANTORS' COVENANTS. In addition to the other covenants and
agreements set forth herein and in the other Operative Documents, each Grantor
covenants and agrees as follows:

                  (a) Such Grantor will pay, prior to delinquency, all taxes,
charges, Liens and assessments against the Collateral owned by it, except those

appropriate proceedings and with respect to which reserves in conformity with
GAAP have been provided on the books of such Grantor and except those which
could not reasonably be expected to have a Material Adverse Effect.

                  (b) The Collateral owned by it will not be used in violation

without limitation, all applicable regulations,
<PAGE>
                                       21

be produced in compliance with all requirements of applicable law, including,

and applicable, will otherwise deal with the Collateral in all such ways as are
considered customary practice by owners of like property.

                  (e) Such Grantor will take all reasonable steps to preserve
and protect the Collateral owned by it except where the failure to do so could
not reasonably be expected to have a Material Adverse Effect.

pursuant to the terms of the Purchase Agreement.

                  (g) Such Grantor will promptly notify the Agent in writing in

any location of Collateral owned by it not listed in Schedule 3-A, (ii) move its
principal place of business, chief executive offices or any other office listed
in Schedule 3-D, (iii) change its jurisdiction of incorporation or organization,
or (iv) adopt, use or conduct business under any trade name or other corporate
or fictitious name not disclosed in Schedule 3-E, except upon not less than 30
days prior written notice to the Agent and such Grantor's prior compliance with
all applicable requirements of Section 4 hereof necessary to perfect the Agent's
security interest hereunder.

                  (i) Such Grantor shall cause all of its equipment constituting
Collateral owned by it to be operated in accordance with any applicable
manufacturer's manuals or instructions and the requirements of its insurance
policies. Such Grantor, at its expense, shall maintain such equipment in good
condition, reasonable wear and tear excepted, and will comply with all laws,
ordinances and regulations to which the use and operation of such equipment may
be or become subject. Such obligation shall extend to repair and replacement of
any partial loss or damage to such equipment, regardless of the cause. All parts
furnished in connection with such maintenance or repair shall immediately become
part of such equipment. All such maintenance, repair and replacement services
shall be promptly paid for and discharged by such Grantor with the result that
no lien will attach to such equipment. Only qualified personnel of such Grantor
or qualified contract personnel shall operate such equipment. Such equipment
shall be used only for the purposes for which it was designed.

                  (j) Such Grantor shall, promptly, upon the release of all
Liens related to the NAS Agreement, take all actions necessary, including,
without limitation, the actions contemplated in Section 8 hereof, to grant to

                  (k) Such Grantor shall comply in all material respects, with
the terms and conditions of all material agreements, commitments or instruments
to which such Grantor is a party or by which it is bound. Such Grantor shall
duly comply in all material respects, with any applicable laws, ordinances,
rules and regulations of any foreign, federal, state or local government or any

governmental authorities relating to the conduct of its business, properties or
assets.

                  (l) Such Grantor shall maintain in all material respects, all

the continuance of an Event of Default, upon notice from the Agent to the
Grantors, each Grantor's right to make collections on and receive dividends and
other proceeds of the Collateral owned by it and to use or dispose of such
collections and proceeds shall terminate, and any and all dividends, proceeds

thereafter received on or on account of the Collateral will be held or received
by such Grantor in trust for the Agent and promptly delivered in kind to the
Agent (duly endorsed to the Agent, if required), to be held as Collateral, as

deposit and deliver, in the name of any of the Grantors, any and all checks,
notes, drafts and other instruments for the payment of money constituting
proceeds of or otherwise relating to the Collateral; and each Grantor hereby
authorizes the Agent to affix, by facsimile signature or otherwise, the general
or special endorsement of such Grantor, in such manner as the Agent shall deem
advisable, to any such instrument in the event the same has been delivered to or
obtained by the Agent without appropriate endorsement, and the Agent and any
collecting bank are hereby authorized to consider such endorsement to be a
sufficient, valid and effective endorsement by such Grantor, to the same extent
as though it were manually executed by the duly authorized representative of
such Grantor, regardless of by whom or under what circumstances or by what
authority such endorsement actually is affixed, without duty of inquiry or
responsibility as to such matters, and such Grantor hereby expressly waives
demand, presentment, protest and notice of protest or dishonor and all other
notices of every kind and nature with respect to any such instrument.

the UCC as enacted in any such jurisdiction in effect at that time, and in
addition the following rights and remedies in accordance with applicable law,
all of which may be exercised only at the direction of the Majority Investors
with or without further prior notice to the Grantors except such notice as may
be specifically required by applicable law: (i) to foreclose the Liens and
security interests created under any Operative Document by any available
judicial procedure or without judicial process; (ii) to enter peaceably any
premises where any Collateral may be located for the purpose of securing,
protecting, inventorying, appraising, inspecting, repairing, preserving,
storing, preparing, processing, taking possession of or removing the same; (iii)
to sell, assign, lease or otherwise dispose of any Collateral or any part
thereof, either at public or private sale or at any broker's board, in lot or in
bulk, for cash, on credit or otherwise, with or without representations or
warranties and upon such terms as shall be commercially reasonable; (iv) to
notify obligors on the Collateral that the Collateral has been assigned to the
Agent and that all payments thereon, or performance with respect thereto, are to
be made directly and exclusively to the Agent; (v) to collect by legal
proceedings or otherwise all dividends, distributions, interest, principal or
other sums now or hereafter payable upon or on account of the Collateral; (vi)
to enter into any extension, reorganization, disposition, merger or
consolidation agreement, or any other agreement relating to or affecting the
Collateral, and in connection therewith the Agent may deposit or surrender
control of the Collateral and/or accept other property in exchange for the
Collateral as the Agent reasonably deems appropriate and is commercially
reasonable; (vii) to settle, compromise or release, on terms acceptable to the
Agent, in whole or in part, any amounts owing on the Collateral and/or any
disputes with respect thereto; (viii) to extend the time of payment, make
allowances and adjustments and issue credits in connection with the Collateral
in the name of the applicable Grantor for the benefit of the Agent; (ix) to
enforce payment and prosecute any action or proceeding with respect to any or
all of the Collateral and take or bring, on behalf of itself or in the name of
the applicable Grantor, any and all steps, actions, suits or proceedings deemed
necessary or reasonably desirable by the Agent to effect collection of or to
realize upon the Collateral, including any judicial or nonjudicial foreclosure
thereof or thereon, and each Grantor specifically consents to any nonjudicial
foreclosure of any or all of the Collateral or any other action taken by the
Agent which may release any obligor from personal liability on any of the
Collateral, and each Grantor waives, to the extent permitted by applicable law,
any right to receive prior notice of any public or private judicial or
nonjudicial sale or foreclosure of any security or any of the Collateral, and
any money or other property received by the Agent in exchange for or on account
of the Collateral, whether representing collections or proceeds of Collateral,
and whether resulting from voluntary payments or foreclosure proceedings or
other legal action taken by the Agent or any of the Grantors, may be applied by
the Agent, without notice to the Grantors, to decrease the amount owed by the
Company under the Notes in such order and manner as described in the Notes; (x)
to insure, protect and preserve the Collateral; (xi) to exercise all rights,
remedies, powers or privileges provided under any of the Operative Documents or
the Purchase Agreement; and (xii) to remove peaceably, from any premises where
the same may be located, the Collateral and any and all documents, instruments,
files and records, and any receptacles and cabinets containing the same,
relating to the Collateral, and the Agent may, at the cost and expense of the
Grantors and subject to the rights of third parties, use such of its supplies,
equipment, facilities and space at its places of business as may be necessary or
appropriate to properly administer, process, store, control, prepare for sale or
disposition and/or sell or dispose of the Collateral or to properly administer
and control the handling of collections and realizations thereon, and, subject
to the rights of third parties, the Agent shall be deemed to have a rent-free
tenancy of any premises of the Grantors for such purposes and for such periods
of time as reasonably required by the Agent. So long as an Event of Default has
occurred and is continuing, each Grantor will, at the Agent's request, assemble
the Collateral and make it available to the Agent at places which the Agent may
designate, whether at the premises of such Grantor or elsewhere, which are
reasonably convenient to the Agent and the Grantors and will make available to
the Agent, free of cost and subject to the rights of third parties, all
premises, equipment and facilities of such Grantor for the purpose of the
Agent's taking possession of the Collateral or storing the same or removing or
putting the Collateral in salable form or selling or disposing of the same.
<PAGE>
                                       24

                  (b) Possession by the Agent. During the existence of an Event
of Default, the Agent also shall have the right, without prior notice or demand,
either in person, by the Agent or by a receiver to be appointed by a court in
accordance with the provisions of applicable law (and each Grantor hereby
expressly consents, to the fullest extent permitted by applicable law, during
the existence of an Event of Default to the appointment of such a receiver),
and, to the extent permitted by applicable law, without regard to the adequacy
of any security for the Notes, to take possession of the Collateral or any part
thereof and to collect and receive the rents, issues, profits, income and
proceeds thereof. The taking possession of the Collateral by the Agent shall not
cure or waive any Event of Default or notice thereof or invalidate any act done
pursuant to such notice. The rights, remedies and powers of any receiver
appointed by a court shall be as ordered by said court.

                  (c) Sale of Collateral. Any public or private sale or other
disposition of the Collateral pursuant to this Section 15 may be held, subject
to the rights of third parties, at any office of the Agent, or at the Grantors'
places of business, or at any other place permitted by applicable law, and
without the necessity of the Collateral being within the view of prospective
purchasers. The Agent may direct the order and manner of sale of the Collateral,
or portions thereof, as it in its sole and absolute discretion may determine
provided such sale is commercially reasonable, and each Grantor expressly
waives, to the extent permitted by applicable law, any right to direct the order
and manner of sale of any Collateral. The Agent or any Person acting on the
Agent's behalf may bid and purchase at any such sale or other disposition. In
furtherance of the Agent's rights hereunder, each Grantor hereby grants to the
Agent an irrevocable, non-exclusive license (exercisable without royalty or
other payment by the Agent) to use, license or sublicense any patent, trademark,
trade name, copyright or other intellectual property in which Grantor now or
hereafter has any right, title or interest together with the right of access to
all media in which any of the foregoing may be recorded or stored; provided,
however, that such license shall only be exercisable in connection with the
disposition of Collateral upon the Agent's exercise of its remedies hereunder.

                  (d) Notice of Sale. Unless the Collateral is perishable or
threatens to decline speedily in value or is of a type customarily sold on a
recognized market, the Agent will give the Grantors reasonable notice of the
time and place of any public sale thereof or of the time on or after which any
private sale thereof is to be made. The requirement of reasonable notice
conclusively shall be met if such notice is mailed, certified mail, postage
prepaid, to the Grantors at their addresses set forth on the signature page
hereto or delivered or otherwise sent to the Grantors, at least ten (10)
business days before the date of the sale. Each Grantor expressly waives, to the
fullest extent permitted by applicable law, any right to receive notice of any
public or private sale of any Collateral or other security for the Notes except
as expressly provided for in this paragraph. The Agent shall not be obligated to
make any sale of the Collateral if it shall determine not to do so regardless of
the fact that notice of sale of the Collateral may have been given. The Agent
may, without notice or publication, except as required by applicable law,
adjourn the sale from time to time by announcement at the time and place fixed
for sale, and such sale may, without further notice (except as required by
applicable law), be made at the time and place to which the same was so
adjourned.

                  (e) Private Sales. With respect to any Collateral consisting
of securities, partnership interests, limited liability company interests, joint
venture interests or the like, and whether or not any of such Collateral has
been effectively registered under the Securities Act of 1933, as amended, or
other applicable laws, the Agent may, in its sole and absolute discretion, sell
all or any part of such Collateral at private sale pursuant to this Section 15
in such manner and under such circumstances as the Agent may deem necessary or
advisable in order that the sale may be lawfully conducted in a commercially
reasonable manner. Without limiting the foregoing, the Agent may (i) approach
and negotiate with a limited number of potential purchasers, and (ii) restrict
the prospective bidders or purchasers to persons who will represent and agree
that they are purchasing such Collateral for their own account for investment
<PAGE>
                                       25

and not with a view to the distribution or resale thereof. In the event that any
such Collateral is sold at private sale pursuant to this Section 15, each
Grantor agrees to the extent permitted by applicable law that if such Collateral
is sold for a price which is commercially reasonable, then (A) the Grantors
shall not be entitled to a credit against the Notes in an amount in excess of
the purchase price, and (B) the Agent shall not incur any liability or
responsibility to the Grantors in connection therewith, notwithstanding the
possibility that a substantially higher price might have been realized at a
public sale. Each Grantor recognizes that a ready market may not exist for such
Collateral if it is not regularly traded on a recognized securities exchange,
and that a sale by the Agent of any such Collateral for an amount substantially
less than a pro rata share of the fair market value of the issuer's assets minus
liabilities may be commercially reasonable in view of the difficulties that may
be encountered in attempting to sell a large amount of such Collateral or
Collateral that is privately traded.

                  (f) Title of Purchasers. Upon consummation of any sale of
Collateral hereunder, the Agent shall have the right to assign, transfer and
deliver to the purchaser or purchasers thereof the Collateral so sold. Each such
purchaser at any such sale shall hold the Collateral so sold absolutely free
from any claim or right upon the part of any Grantor or any other Person
claiming through any Grantor, and each Grantor hereby waives (to the extent
permitted by applicable laws) all rights of redemption, stay and appraisal which
it now has or may at any time in the future have under any rule of law or
statute now existing or hereafter enacted. If the sale of all or any part of the
Collateral hereunder is made on credit or for future delivery, the Agent shall
not be required to apply any portion of the sale price to the Notes until such
amount actually is received by the Agent, and any Collateral so sold may be
retained by the Agent until the sale price is paid in full by the purchaser or
purchasers thereof. The Agent shall not incur any liability in case any such
purchaser or purchasers shall fail to pay for the Collateral so sold, and, in
case of any such failure, the Collateral may be sold again.

                  (g) Disposition of Proceeds of Sale. The proceeds resulting
from the collection, liquidation, sale or other disposition of the Collateral
hereunder shall be applied, first, to the reasonable costs and expenses
(including reasonable attorneys' fees) of retaking, holding, storing, processing
and preparing for sale, selling, collecting and liquidating the Collateral, and
the like; and second, to the satisfaction of all obligations under or in respect
of the Notes; and third, any surplus remaining after the satisfaction of all
obligations under or in respect of the Notes, to be paid over to the Grantors or
to whomsoever may be lawfully entitled to receive such surplus.

                  (h) Certain Waivers. To the extent permitted by applicable
law, each Grantor waives all claims, damages and demands against the Agent
arising out of the repossession, retention or sale of the Collateral, or any
part or parts thereof hereunder, except to the extent any such claims, damages
and awards arise out of the gross negligence or willful misconduct of the Agent.

                  (i) Remedies Cumulative. The rights and remedies provided
under this Agreement are cumulative and may be exercised singly or concurrently,
and are not exclusive of any other rights and remedies provided by law or
equity.

            18. INSURANCE.

                  (a) Each Grantor will, at its own expense, maintain insurance
with respect to the Equipment and Inventory of such Grantor in amounts, against
risks, in form and with insurers consistent with its normal business practice.
Each policy of each Grantor for liability insurance shall provide for all
covered losses to be paid on behalf of the Agent and such Grantor as their
interests may appear, and each policy for property damage insurance shall
provide for all covered losses (except for losses of less than $50,000 per
occurrence) to be paid directly to the Deposit Account bearing account number
94077-15973 held at Fleet Bank, with notice by the applicable Grantor to the
Agent or, if the Agent so elects, directly to
<PAGE>
                                       26

the Agent. Notwithstanding the foregoing, only the World Trade Center claim
beginning September 11, 2001 and the computer virus related claims beginning
July 13, 2001, August 7, 2001 and September 17, 2001, respectively, in each case
filed prior to the date hereof and payable under the Chubb Property Damage
Insurance Policy bearing policy number 3539-79-82NHO, shall be paid directly to
the relevant Grantor. Each policy for property damage insurance shall in
addition (i) name such Grantor and the Agent as insured parties thereunder
(without any representation or warranty by or obligation upon the Agent) as
their interests may appear, (ii) contain the agreement by the insurer that any
loss payable thereunder to the Grantor shall be payable to the Deposit Account
bearing account number 94077-15973 held at Fleet Bank, with notice by the
applicable Grantor or, if the Agent so elects, directly to the Agent
notwithstanding any action, inaction or breach of representation or warranty by
such Grantor, (iii) provide that there shall be no recourse against the Agent
for payment of premiums or other amounts with respect thereto and (iv) provide
that at least ten (10) days' prior written notice of cancellation or of lapse
shall be given to the Agent by the insurer. Each Grantor will, if so requested
by the Agent, deliver to the Agent original or duplicate policies of such
insurance and, as often as the Agent may reasonably request, a report of a
reputable insurance broker with respect to such insurance. Further, each Grantor
will, at the request of the Agent following the occurrence of any Default, duly
execute and deliver instruments of assignment of such insurance policies to
comply with the requirements of this Section and use its best efforts to cause
the insurers to acknowledge notice of such assignment.

                  (b) Payment under any liability insurance maintained by any
Grantor pursuant to this Section will be paid directly to the Person who shall
have incurred liability covered by such insurance. In case of any loss involving
damage to Equipment or Inventory when subsection (c) of this Section is not
applicable, the applicable Grantor will make or cause to be made the necessary
repairs to or replacements of such Equipment or Inventory, and any proceeds of
insurance properly received by or released to such Grantor shall be used by such
Grantor, except as otherwise required hereunder or by the Purchase Agreement, to
pay or as reimbursement for the costs of such repairs or replacements.

                  (c) So long as no Default shall have occurred and be
continuing, all insurance payments received into the applicable Deposit Account
or by the Agent in connection with any loss, damage or destruction of any
Inventory or Equipment shall be used by the applicable Grantor for the repair,
replacement or restoration thereof, subject to such terms and conditions with
respect to the use thereof as the Agent may reasonably require. To the extent
that (i) the amount of any such insurance payments exceeds the cost of any such
repair, replacement or restoration, or (ii) such insurance payments are not
otherwise required by the applicable Grantor to complete any such repair,
replacement or restoration required hereunder, the Agent may require that the
amount thereof be held in the applicable Deposit Account. Upon the occurrence
and during the continuance of any Default or the actual or constructive total
loss (in excess of $50,000 per occurrence) of any Equipment or Inventory, all
insurance payments in respect of such Equipment or Inventory shall be paid to
the Agent and shall, in the Agent's sole discretion, (i) be released to the
applicable Grantor to be applied as set forth in the first sentence of this
subsection (c) or (ii) be held as additional Collateral hereunder.

            19. NOTICE. The Agent shall use reasonable efforts to give the
Grantors reasonable prior written notice of the exercise of any remedy provided
for herein, provided that the failure to give such notice shall not subject the
Agent to liability and shall not affect the validity or exercise of any remedy
hereunder.

            20. COSTS AND EXPENSES. Each Grantor shall pay on demand (i) all
reasonable fees and expenses, including reasonable attorneys' fees and expenses,
incurred by the Agent in connection with the exercise of its duties under, this
Agreement and the preparation, execution and delivery of amendments and waivers
hereunder and (ii) all reasonable fees and expenses, including reasonable
attorneys' fees and expenses, incurred by the Agent and the Investors in
connection with the enforcement or attempted
<PAGE>
                                       27

enforcement of this Agreement or any of the Notes or in preserving any of the
Agent's rights and remedies (including, without limitation, all such fees and
expenses incurred in connection with any "workout" or restructuring affecting
the Operative Documents or any bankruptcy or similar proceeding involving such
Grantor, any other Grantor, the Company or any of their Affiliates).

            21. COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original, but all of which taken
together shall constitute one and the same agreement. Delivery of an executed
counterpart of a signature page to this Agreement by telecopier shall be
effective as delivery of an original counterpart of this Agreement.

            22. UNDERSTANDINGS WITH RESPECT TO WAIVERS AND CONSENTS. Each
Grantor warrants and agrees that each of the waivers and consents set forth
herein are made with full knowledge of their significance and consequences, with
the understanding that events giving rise to any defense or right waived may
diminish, destroy or otherwise adversely affect rights which such Grantor
otherwise may have against the Agent or others, or against any Collateral. If
any of the waivers or consents herein are determined to be unenforceable under
applicable law, such waivers and consents shall be effective to the maximum
extent permitted by law.

            23. INDEMNITY.

                  (a) Each Grantor agrees to indemnify, defend and save and hold
harmless the Agent and each Investor and each of their Affiliates and their
respective officers, directors, employees, agents and advisors (each, an
"Indemnified Party") from and against, and shall pay on demand, any and all
claims, damages, losses, liabilities and expenses (including, without
limitation, reasonable fees and expenses of counsel) that may reasonably be
incurred by or asserted or awarded against any Indemnified Party, in each case
arising out of or in connection with or resulting from any Operative Document
(including, without limitation, enforcement of any Operative Document), except
to the extent such claim, damage, loss, liability or expense is found in a
final, non-appealable judgment by a court of competent jurisdiction to have
resulted from such Indemnified Party's gross negligence or willful misconduct;

                  (b) Each Grantor will upon demand pay to the Agent the amount
of any and all reasonable expenses, including, without limitation, the
reasonable fees and expenses of its counsel and of any experts and agents, that
the Agent may reasonably incur in connection with (i) the administration of any
Operative Document, (ii) the custody, preservation, use or operation of, or the
sale of, collection from or other realization upon, any of the Collateral of
such Grantor or (iii) the exercise or enforcement of any of the rights of the
Agent or the Investors hereunder or (iv) the failure by such Grantor to perform
or observe any of the provisions of any Operative Document. In the case of any
investigation, litigation or proceeding giving rise to any Indemnified Costs,
this Section 23 applies whether any such investigation, litigation or proceeding
is brought by any Grantor, Indemnified Party or any other Person and whether or
not an Indemnified Party is otherwise a party thereto.

                  (c) Each Investor severally agrees to indemnify the Agent (to
the extent not promptly reimbursed by the Grantors) from and against such
Investor's ratable share (determined as provided below) of any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever that may
reasonably be imposed on, incurred by, or asserted against the Agent in any way
relating to or arising out of the Operative Documents or any action taken or
omitted by the Agent under the Operative Documents (collectively, the
"Indemnified Costs"); provided, however, that no Investor shall be liable for
any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting from the
Agent's gross negligence or willful misconduct as found in a final,
non-appealable judgment by a court of
<PAGE>
                                       28

competent jurisdiction. Without limitation of the foregoing, each Investor
agrees to reimburse the Agent promptly upon demand for its ratable share of any
costs and expenses (including, without limitation, fees and expenses of counsel)
payable by the Grantors under any Operative Document, to the extent that the
Agent is not promptly reimbursed for such costs and expenses by the Grantors.
For purposes of this Section 23, the Investors respective ratable shares of any
amount shall be determined, at any time, according to the sum of the aggregate
outstanding principal amount of the Notes at such time owing to the respective
Investor. The failure of any Investor to reimburse the Agent, promptly upon
demand for its ratable share of any amount required to be paid by the Investors
to the Agent, as provided herein and under the Operative Documents, shall not
relieve any other Investor of its obligation hereunder and under the Operative
Documents to reimburse the Agent for its ratable share of such amount, but no
Investor shall be responsible for the failure of any other Investor to reimburse
the Agent for such other Investor's ratable share of such amount.

                  (d) Without prejudice to the survival of any other agreement
of any party hereunder, the agreement and obligations of each Grantor and
Investor contained in this Section 23 shall survive the payment in full of
principal, interest and all other amounts payable hereunder and under the other
Operative Documents.

            24. AMENDMENTS, WAIVERS, ETC. No amendment of any provision of this
Agreement or the Notes, shall in any event be effective unless the same shall be
in writing and signed by the Company and the Investors holding at least 80% of
the sum of the aggregate unpaid principal amount owing under the Notes. No
waiver of any provision of this Agreement or the Notes, nor consent to any
departure by any Grantor therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Majority Investors, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given. provided, however, that no amendment, waiver
or consent shall, unless in writing and signed by all of the Investors, do any
of the following at any time: (i) change the number of Investors or the
percentage of the aggregate amount outstanding under the Notes that, in each
case, shall be required for the Investors or any of them to take any action
hereunder, (ii) reduce or limit the obligations of any Guarantor under Section 2
or release such Guarantor or otherwise limit such Guarantor's liability with
respect to the obligations owing to the Agents and the Investors, (iii) amend
this Section 24, (iv) reduce the principal of, or interest on, the Notes or any
fees or other amounts payable under any Operative Document, (v) postpone any
date scheduled for any payment of principal of, or interest on, the Notes
pursuant to Section 6 or any date fixed for payment of fees or other amounts
payable under any Operative Document, or (vi) limit the liability of any Grantor
under any of the Operative Documents.

            25. NOTICES. All notices and other communications provided for
hereunder shall be given in writing in the manner and to the addresses set forth
in the Notes.

            26. CONTINUING SECURITY INTEREST: TRANSFER OF NOTES; TERMINATION.
This Agreement shall create a continuing security interest in the Collateral
pursuant to Section 3 hereof and shall (i) remain in full force and effect until
indefeasible payment in full of the Notes (ii) be binding upon each Grantor,
their successors and assigns and (iii) inure, together with the rights and
remedies of the Agent and the Investors hereunder, to the benefit of the Agent
and the Investors and their respective successors, transferees and assigns. Any
Investor may assign or otherwise transfer its rights thereof, or any rights in
Collateral held by it to any other Person, and such other Person shall thereupon
become vested with all the benefits in respect thereof granted to such Investor
or the Agent herein or otherwise. Nothing set forth in any Operative Document is
intended or shall be construed to give to any other party any right, remedy or
claim under, to or in respect of any Operative Document or any Collateral. The
Grantors' successors and assigns shall include, without limitation, a receiver,
trustee or debtor-in-possession thereof or therefor, provided that, except as
otherwise permitted under the Purchase Agreement or any Operative
<PAGE>
                                       29

Document, none of the rights or obligations of the Grantors hereunder may be
assigned or otherwise transferred without the prior written consent of the
Agent.

            27. RELEASE OF THE GRANTORS. This Agreement and all obligations of
each Grantor hereunder and all security interests granted hereby shall terminate
and be released when all Notes and all other obligations of the Grantors under
or in respect of the Operative Documents have been paid in full. Upon such
termination and release all rights in and to the Collateral granted or pledged
by the Grantors hereunder shall automatically revert to the Grantors, and the
Agent shall return any pledged Collateral in its possession to the Grantors, or
to the Person or Persons legally entitled thereto, and shall endorse, execute,
deliver, record and file all instruments and documents, and do all other acts
and things, reasonably required for the return of the Collateral to the
Grantors, or to the Person or Persons legally entitled thereto, and to evidence
or document the release of the interests of the Agent arising under this
Agreement, all as reasonably requested by, and at the sole expense of, the
Grantors.

            28. GOVERNING LAW. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York.

            29. JURY TRIAL. Each Grantor, each Investor and the Agent, to the
fullest extent permitted by applicable law, hereby irrevocably waives all right
to trial by jury as to any issue relating hereto in any action, proceeding, or
counterclaim arising out of or relating to this Agreement.

            30. LIMITATION OF LIABILITY. No claim may be made by any Grantor
against any Investor or the Agent or the members, affiliates, directors,
officers, employees, or attorneys of any Investor or the Agent for any special,
indirect, consequential or punitive damages in respect of any claim (whether
based upon any breach of contract, tort, breach of statutory duty or any other
theory of liability) arising out of or related to the transactions contemplated
by this Agreement, or any act, omission or event occurring in connection
therewith and each Grantor hereby waives, releases and agrees not to sue upon
any claim for any such damages, whether or not now accrued and whether or not
known or suspected to exist in its favor.

            31. COVENANT NOT TO ISSUE UNCERTIFICATED SECURITIES. Each Grantor
covenants to the Agent that any Pledged Securities held by it shall be in
certificated form (as contemplated by Article 8 of the UCC), and that it will
not seek to convert all or any part of any Pledged Securities into
uncertificated form (as contemplated by Article 8 of the UCC).

            32. COVENANT NOT TO DILUTE INTERESTS OF THE AGENT IN SECURITIES.
Each Grantor represents, warrants and covenants to the Agent that it will (a)
not at any time cause or permit any subsidiary that is an issuer of Pledged
Securities to issue any capital stock or any warrants, options or other rights
to acquire any capital stock, other than to such Grantor or as otherwise
permitted under the Purchase Agreement and (b) pledge to the Agent in accordance
with the terms hereof, promptly upon its acquisition (directly or indirectly)
thereof, and in any event, within 5 days of such acquisition, any and all shares
of stock or other securities of each issuer of Pledged Securities.

            33. PLEDGED LIMITED LIABILITY COMPANY INTERESTS/COVENANT NOT TO
DILUTE. Each Grantor represents, warrants and covenants to the Agent that it
will (a) not at any time cause or permit any Pledged Entities to issue any
additional membership interests or any other rights or options to acquire any
additional limited liability company interests, or as otherwise permitted under
the Purchase Agreement, and (b) pledge to the Agent in accordance with the terms
hereof, promptly upon its acquisition (directly or indirectly) thereof, and in
any event, within 5 days of such acquisition, any and all additional Limited
Liability Company Interests of each Pledged Entity.
<PAGE>
                                       30

            34. PLEDGED PARTNERSHIP INTERESTS/COVENANT NOT TO DILUTE. Each
Grantor represents, warrants and covenants to the Agent that it will (a) not at
any time cause or permit any Pledged Partnership Entities to issue any
additional partnership interests or any other rights or options to acquire any
additional partnership interests, other than to the Grantors or as otherwise
permitted under the Purchase Agreement, and (b) pledge to the Agent in
accordance with the terms hereof, promptly upon its acquisition (directly or

and all additional Partnership Interests of each Pledged Partnership Entity.

            35. CONFIDENTIALITY. The Agent and each Investor agree to use the
same degree of care to safeguard and prevent disclosure of the Confidential
Information as such Person uses with its own confidential information, but in
any event no less than a reasonable degree of care. The Agent and each Investor
shall not disclose such Confidential Information to any Person without the
consent of the Grantors and shall use such Confidential Information solely for
purposes of the exercise of its rights and the enforcement of its remedies under
or in respect of the Operative Documents. These obligations of confidentiality
shall not apply to any information provided (a) to the Agent's or such
Investor's Affiliates and their officers, directors, employees, agents and
advisors, and then only on a confidential basis (and the Agent and such Investor
shall be responsible for any disclosure or misuse of such Confidential
Information by such Person), (b) as required by any law, rule or regulation or
judicial process, (c) as requested or required by any state, Federal or foreign
authority or examiner regulating such Investor and (d) to any rating agency when
required by it, provided that, prior to any such disclosure, such rating agency
shall undertake to preserve the confidentiality of any Confidential Information
relating to the Grantors received by it from such Investor and provided further,
that this Section 35 shall not apply to information related to the tax treatment
or the Tax Structure (as defined below) of the transactions contemplated herein.
For this purpose "Tax Structure" is limited to any facts relevant to the U.S.
federal income tax treatment of the transactions contemplated by the Operative
Documents and does not include information relating to the identity of the
parties thereto.

                   To Agency, Guaranty and Security Agreement

                        FORM OF ACCOUNT CONTROL AGREEMENT
                                (Deposit Account)

            ACCOUNT CONTROL AGREEMENT (this "Agreement") dated as of ________,
____, among____________, a ___________ (the "Grantor"), Deutsche Bank Trust
Company Americas, a ___________, as Administrative Agent (the "Secured Party"),
and _________, a _________ ("____________"), as securities intermediary and
depository bank (the "Account Holder").

PRELIMINARY STATEMENTS:

            (1) The Grantor has granted the Secured Party a security interest
(the "Security Interest") in the following accounts maintained by the Account
Holder for the Grantor (each, an "Account" and collectively, the "Accounts"):

           [Insert account numbers and other identifying information.]

            (2) Terms defined in Article 8 or 9 of the Uniform Commercial Code
in effect in the State of New York ("N.Y. Uniform Commercial Code") are used in
this Agreement as such terms are defined in such Article 8 or 9.

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

            SECTION 1. The Accounts. The Grantor and Account Holder represent
and warrant to, and agrees with, the Secured Party that:

            (a) The Account Holder maintains each Account for the Grantor, and
all property (including, without limitation, all funds and financial assets)
held by the Account Holder for the account of the Grantor are, and will continue
to be, credited to an Account in accordance with instructions given by the
Grantor (unless otherwise provided herein).

            (b) To the extent that funds are credited to any Account, such
Account is a deposit account; and to the extent that financial assets are
credited to any Account, such Account is a securities account. The Account
Holder is (i) the bank with which each Account that is a deposit account is
maintained and (ii) the securities intermediary with respect to financial assets
held in any Account that is a securities account. The Grantor is (x) the Account
Holder's customer with respect to the Accounts and (y) the entitlement holder
with respect to financial assets credited from time to time to any Account.

            (c) Notwithstanding any other agreement to the contrary, the Account
Holder's jurisdiction with respect to each Account for purposes of the N.Y.
Uniform Commercial Code is, and will continue to be for so long as the Security
Interest shall be in effect, the State of New York.

            (d) Attached as Exhibit A hereto are statements of the respective
Accounts as of the date hereof showing the property credited to each Account.
<PAGE>

            (e) The Grantor and Account Holder do not know of any claim to or
interest in any Account or any property (including, without limitation, funds
and financial assets) credited to any Account, except for claims and interests
of the parties referred to in this Agreement.

            SECTION 2. Control by Secured Party. The Account Holder will comply
with (i) all instructions directing disposition of the funds in any and all of
the Accounts, (ii) all notifications and entitlement orders that the Account
Holder receives directing it to transfer or redeem any financial asset in any
and all of the Accounts, and (iii) all other directions concerning any and all
of the Accounts, including, without limitation, directions to distribute to the
Secured Party proceeds of any such transfer or redemption or interest or
dividends on property in any and all of the Accounts (any such instruction,
notification or direction referred to in clause (i), (ii) or (iii) above being
an "Account Direction"), in each case of clauses (i), (ii) and (iii) above
originated by the Secured Party without further consent by the Grantor or any
other Person.

            SECTION 3. Grantor's Rights in Accounts.

            (a) Except as otherwise provided in this Section 3, the Account
Holder will comply with Account Directions and other directions concerning each
Account originated by the Grantor without further consent by the Secured Party.

            (b) Until the Account Holder receives a notice from the Secured
Party that the Secured Party will exercise exclusive control over any Account,
which notice shall only be delivered by the Secured Party during an Event of
Default as defined in the Agency and Security Agreement, a copy of which notice
shall also be sent to Grantor (a "Notice of Exclusive Control" with respect to
such Account, the form of which is attached hereto as Exhibit B), the Account
Holder may distribute to the Grantor all interest and regular cash dividends on
property (including, without limitation, funds and financial assets) in such
Account.

            (c) If the Account Holder receives from the Secured Party a Notice
of Exclusive Control with respect to any Account, the Account Holder will not
comply with any Account Direction originated by the Grantor that would require
the Account Holder to make a free delivery of any funds or financial asset to
the Grantor or any other Person.

            (d) If the Account Holder receives from the Secured Party a Notice
of Exclusive Control with respect to any Account, the Account Holder will comply
only with Account Directions originated by the Secured Party and will cease:

                  (i) complying with Account Directions or other directions
concerning such Account originated by the Grantor and

                  (ii) distributing to the Grantor interest and dividends on
property (including, without limitation, funds and financial assets) in such
Account.

            SECTION 4. Priority of Secured Party's Security Interest. (a) The
Account Holder (i) subordinates to the Security Interest and in favor of the
Secured Party any security interest, lien, or right of recoupment or setoff that
the Account Holder may have, now or in the future, against any Account or
property (including, without limitation, any funds and financial assets)
credited to any Account, and (ii) agrees that it will not exercise any right in
respect of any such security interest or lien or any such right of recoupment or
setoff until the Security Interest is terminated, except that the Account Holder
(A) will retain its prior security interest and lien on property credited to any
Account, (B) may exercise any right in respect of such security interest or
lien, and (C) may exercise any right of
<PAGE>

recoupment or setoff against any Account, in the case of clauses (A), (B) and
(C) above, to secure or to satisfy, and only to secure or to satisfy, payment
(x) for such property, (y) for its customary fees and expenses for the routine
maintenance and operation of such Account, and (z) if such Account is a deposit
account, for the face amount of any items that have been credited to such
Account but are subsequently returned unpaid because of uncollected or
insufficient funds.

            (b) The Account Holder will not enter into any other agreement with
any Person relating to Account Directions or other directions with respect to
any Account.

            SECTION 5. Statements, Confirmations, and Notices of Adverse Claims.
(a) The Account Holder will send copies of all statements and confirmations for
each Account simultaneously to the Secured Party and the Grantor.

            (b) When the Account Holder knows of any claim or interest in any
Account or any property (including, without limitation, funds and financial
assets) credited to any Account other than the claims and interests of the
parties referred to in this Agreement, the Account Holder will promptly notify
the Secured Party and the Grantor of such claim or interest.

            SECTION 6. The Account Holder's Responsibility. (a) Except for
permitting a withdrawal, delivery, or payment in violation of Section 3, the
Account Holder will not be liable to the Secured Party for complying with
Account Directions or other directions concerning any Account from the Grantor
that are received by the Account Holder before the Account Holder receives and
has a reasonable opportunity to act on a Notice of Exclusive Control.

            (b) The Account Holder will not be liable to the Grantor or the
Secured Party for complying with a Notice of Exclusive Control or with an
Account Direction or other direction concerning any Account originated by the
Secured Party, even if the Grantor notifies the Account Holder that the Secured
Party is not legally entitled to issue the Notice of Exclusive Control or
Account Direction or such other direction unless the Account Holder takes the
action after it is served with an injunction, restraining order, or other legal
process enjoining it from doing so, issued by a court of competent jurisdiction,
and had a reasonable opportunity to act on the injunction, restraining order or
other legal process.

            (c) This Agreement does not create any obligation of the Account
Holder except for those expressly set forth in this Agreement and, in the case
of any Account that is a securities account, in Part 5 of Article 8 of the N.Y.
Uniform Commercial Code and, in the case of any Account that is a deposit
account, in Article 4 of the N.Y. Uniform Commercial Code. In particular, the
Account Holder need not investigate whether the Secured Party is entitled under
the Secured Party's agreements with the Grantor to give an Account Direction or
other direction concerning any Account or a Notice of Exclusive Control. The
Account Holder may rely on notices and communications it believes given by the
appropriate party.

            SECTION 7. Indemnity. The Grantor will indemnify the Account Holder,
its officers, directors, employees and agents against claims, liabilities and
expenses arising out of this Agreement (including, without limitation,
reasonable attorney's fees and disbursements), except to the extent the claims,
liabilities or expenses are caused by the Account Holder's gross negligence or
willful misconduct as found by a court of competent jurisdiction in a final,
non-appealable judgment.

            SECTION 8. Termination; Survival. (a) The Secured Party may
terminate this Agreement by notice to the Account Holder and the Grantor. If the
Secured Party notifies the Account Holder that the Security Interest has
terminated, this Agreement will immediately terminate.
<PAGE>

            (b) The Account Holder may terminate this Agreement on 60 days'
prior notice to the Secured Party and the Grantor, provided that before such
termination the Account Holder and the Grantor shall make arrangements to
transfer the property (including, without limitation, all funds and financial
assets) credited to each Account to another Account Holder that shall have
executed, together with the Grantor, a control agreement in favor of the Secured
Party in respect of such property in substantially the form of this Agreement or
otherwise in form and substance satisfactory to the Secured Party.

            (c) Sections 6 and 7 will survive termination of this Agreement.

            SECTION 9. Governing Law. This Agreement and each Account will be
governed by the law of the State of New York. The Account Holder and the Grantor
may not change the law governing any Account without the Secured Party's express
prior written agreement.

            SECTION 10. Entire Agreement. This Agreement is the entire
agreement, and supersedes any prior agreements, and contemporaneous oral
agreements, of the parties concerning its subject matter.

            SECTION 11. Amendments. No amendment of, or waiver of a right under,
this Agreement will be binding unless it is in writing and signed by the party
to be charged.

            SECTION 12. Financial Assets. The Account Holder agrees with the
Secured Party and the Grantor that, to the fullest extent permitted by
applicable law, all property (other than funds) credited from time to time to
any Account will be treated as financial assets under Article 8 of the N.Y.
Uniform Commercial Code.

            SECTION 13. Notices. A notice or other communication to a party
under this Agreement will be in writing (except that Account Directions may be
given orally), will be sent to the party's address set forth under its name
below or to such other address as the party may notify the other parties and
will be effective on receipt.

            SECTION 14. Binding Effect. This Agreement shall become effective
when it shall have been executed by the Grantor, the Secured Party and the
Account Holder, and thereafter shall be binding upon and inure to the benefit of
the Grantor, the Secured Party and the Account Holder and their respective
successors and assigns.

            SECTION 15. Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of an original executed
counterpart of this Agreement.

            IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be executed by their respective officers thereunto duly authorized, as of the
date first above written.

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

                                VOTING AGREEMENT

            THIS VOTING AGREEMENT, dated as of July 18, 2003 (this "Agreement"),
is made and entered into by and among DSL.net, Inc., a Delaware corporation
("DSLN"), certain stockholders of DSLN who have executed a signature page hereto
(each a "Stockholder," and collectively, the "Stockholders") and the Investors
listed on the signature pages hereto (collectively, the "Investors").

                                    PREAMBLE

            The Stockholders are stockholders of DSLN and desire that DSLN and
the Investors enter into the Note and Warrant Purchase Agreement dated as of the
date hereof (the "Purchase Agreement") among DSLN and the Investors with respect
to the sale of certain Notes and Warrants to the Investors set forth therein.
The Stockholders are executing this Agreement as an inducement to DSLN and the
Investors to enter into and execute the Purchase Agreement.

            All capitalized terms used herein which are not defined herein shall
have the same meanings as ascribed to them in the Purchase Agreement.

            NOW, THEREFORE, in consideration of the execution and delivery by
DSLN and the Investors of the Purchase Agreement and the mutual covenants,
conditions and agreements contained herein and therein, the parties agree as
follows:

            1. REPRESENTATIONS AND WARRANTIES. (a) The Stockholders severally
and not jointly represent and warrant to DSLN and the Investors as follows:

                                    (i) As of the date hereof, the Stockholders
            are the record owners of the DSLN Common Stock, the Series X
            Preferred Stock, the Series Y Preferred Stock or warrants (listed on
            an as-if-converted to DSLN Common Stock basis) set forth on Schedule
            1 to this Agreement. Except for the DSLN Capital Stock set forth on
            Schedule 1 to this Agreement, the Stockholders are not the record
            owner of any other shares of DSLN Capital Stock. "DSLN Capital
            Stock" shall mean the DSLN Common Stock, the Series X Preferred
            Stock and the Series Y Preferred Stock. The DSLN Capital Stock set
            forth on Schedule 1 to this Agreement and any other DSLN Capital
            Stock (including Common Stock issuable pursuant to the warrants set
            forth on Schedule 1) or other voting stock of DSLN that the
            Stockholders may acquire in the future are referred to herein as the
            "Shares." This Agreement has been duly authorized, executed and
            delivered by, and constitutes a valid and binding agreement of, the
            Stockholders, enforceable in accordance with its terms, except as
            enforceability may be limited by applicable bankruptcy, insolvency,
            reorganization, moratorium or similar laws affecting creditors
            rights generally or the availability of equitable remedies, and the
            execution and delivery of this Agreement will not violate or result
            in a default under any agreement to which the Stockholders are a
            party. Neither the execution and delivery of this Agreement nor the

            consummation by the Stockholders of the transactions contemplated
            hereby will (A) conflict with or violate, or require any consent,
            approval or notice under any provision of any judgment, order,
            decree, statute, law, rule or regulation applicable to a Stockholder
            or a Stockholder's Shares or (B) constitute a violation of, conflict
            with or constitute a default under, any contract, commitment,
            agreement, understanding, arrangement or other restriction of any
            kind to which a Stockholder is a party or by which a Stockholder is
            bound.

                                    (ii) Except as permitted by Section 3, each
            Stockholder's Shares and the certificates representing such Shares
            are now and at all times during the term hereof will be held by each
            Stockholder, free and clear of all liens, claims, security
            interests, proxies, voting trusts or agreements, understandings or
            arrangements or any other encumbrances whatsoever that would
            interfere with the voting of the Shares or the granting of any proxy
            with respect to the subject matter of the proxy granted in Section 2
            below, except for any such encumbrances or proxies arising
            hereunder.

                                    (iii) The DSLN Capital Stock set forth on
            Schedule 1 and held by the  Stockholders  as of the date  hereof is
            subject to this Agreement and is sufficient, if voted in accordance
            with the terms hereof, under the Delaware General Corporation Law
            and the Company's certificate of incorporation and by-laws to obtain
            the Required Stockholder Approvals, regardless of whether all
            options, warrants, rights or agreements for the purchase or
            acquisition of any DSLN Capital Stock or other voting stock of DSLN
            that may be exercised by any Person prior to any DSLN Stockholders
            Meeting are exercised.

                                    (iv) The Stockholders understand and
            acknowledge that any DSLN Capital Stock or other voting stock of the
            Company that the Stockholders purchase or with respect to which the
            Stockholders otherwise acquire beneficial ownership after the date
            of this Agreement and prior to the Termination Date shall be subject
            to the terms and conditions of this Agreement to the same extent as
            if they constituted Shares as of the date hereof.

                                    (v) The Stockholders understand and
            acknowledge that DSLN and the Investors are entering the Purchase
            Agreement in reliance upon the Stockholders' execution and delivery
            of this Agreement. The Stockholders acknowledge that the irrevocable
            proxy set forth in Section 4 is granted in consideration for the
            execution and delivery of the Purchase Agreement by DSLN and the
            Investors.

            (b) DSLN and each of the Investors severally and not jointly
represent and warrant to the Stockholders as follows:

                                    (i) This Agreement has been duly authorized,
            executed and delivered by and constitutes a valid and binding
            agreement of it, enforceable in accordance with its terms except as
            enforceability may be limited by applicable bankruptcy, insolvency
            or similar laws affecting creditors' rights generally or the
            availability of equitable remedies,

                                        2
<PAGE>

            and the execution and delivery of this Agreement will not violate or
            result in a default under any agreement to which it is a party.
            Neither the execution and delivery of this Agreement nor the
            consummation by it of the transactions contemplated hereby will (A)
            violate, or require any consent, approval or notice under any
            provision of any judgment, order, decree, statute, law, rule or
            regulation applicable to it or (B) constitute a violation of,
            conflict with or constitute a default under, any contract,
            commitment, agreement, understanding, arrangement or other
            restriction of any kind to which it is a party or by which it is
            bound.

            2. VOTING AGREEMENT. The Stockholders severally agree with, and
covenant to, DSLN and the Investors that, during the term of this Agreement, at
any meeting of DSLN stockholders called for the purpose of approving the
transactions contemplated by the Purchase Agreement, including the Required
Stockholder Approvals and all other meetings of Stockholders related thereto
(each, a "DSLN Stockholders Meeting"), or at any adjournment thereof or in any
other circumstances upon which a vote, consent, agreement or other approval is
sought for the purpose of approving the transactions contemplated by the
Purchase Agreement, including the Required Stockholder Approvals, the
Stockholders shall vote (or cause to be voted) the Stockholder's Shares (and all
shares of DSLN Capital Stock for which such Stockholder has been granted a proxy
to the extent permitted thereby), and shall otherwise consent or agree to vote,
in favor of the issuances of the Notes and Warrants as proposed under the
Purchase Agreement and each of the amendments to DSLN's certificate of
incorporation set forth in Exhibit A hereto. The Stockholders, as holders of
DSLN Capital Stock, shall be present in person or by proxy at all meetings of
stockholders of DSLN so that all Shares are counted for purposes of determining
the presence of a quorum at such meetings.

            3. COVENANTS. The Stockholders severally agree with, and covenant
to, DSLN and the Investors that prior to the termination of this Agreement, the
Stockholders shall not (i) without the prior written consent of DSLN and the DB
Investors (which consent shall not be unreasonably withheld if the transferee
executes this Agreement at the time of the transfer) transfer (which term shall
include, without limitation, for the purposes of this Agreement, any sale, gift,
pledge, or consent to any transfer of) any or all of a Stockholder's Shares or
any interest therein; (ii) enter into any contract, option or other agreement or
understanding with respect to any transfer of any or all of such Shares or any
interest therein; (iii) grant any proxy, power of attorney or other
authorization in or with respect to such Shares other than pursuant hereto; or

arrangement with respect to such Shares other than pursuant hereto.

            4. GRANT OF IRREVOCABLE PROXY; APPOINTMENT OF PROXY.

                        (a) Each Stockholder hereby revokes any previous proxies
            relating to its Shares and irrevocably (to the fullest extent
            permitted by Section 212 of the Delaware General Corporation Law)
            grants to, and appoints, David F. Struwas, Robert DeSantis, and
            Stephen Zamansky, each of DSLN, and each of them individually, and
            any individual who shall hereafter succeed such person in such
            office at DSLN, such Stockholder's proxy and attorney-in-fact (with
            full power of substitution), for and in the name, place

                                        3
<PAGE>

            and stead of such Stockholder, to vote such Stockholder's Shares at
            any meeting of stockholders of DSLN (including without limitation
            the DSLN Stockholders Meeting), or at any adjournment thereof or in
            any other circumstances upon which a vote, agreement, consent or
            other approval is sought, on the matters set forth in Section 2
            hereof; provided, however, that such vote shall be restricted to the
            matters set forth in Section 2 and such vote shall be an affirmative
            vote in favor of the transactions contemplated by the Purchase
            Agreement, including the Required Stockholder Approvals. Such
            attorney-in-fact may evidence the taking of any action, giving of
            any consent or the voting of the Shares by the execution of any
            document or instrument for such purpose in the name of such
            Stockholder.

                        (b) Each Stockholder hereby affirms that the irrevocable
            proxy set forth in this Section 4 is given in connection with the
            execution of the Purchase Agreement, and that such irrevocable proxy
            is given to secure the performance of the duties of such Stockholder
            under this Agreement. Each Stockholder hereby further affirms that
            the irrevocable proxy is coupled with an interest and may under no
            circumstances be revoked. Each Stockholder hereby ratifies and
            confirms all that such irrevocable proxy may lawfully do or cause to
            be done by virtue hereof. SUCH IRREVOCABLE PROXY IS EXECUTED AND
            INTENDED TO BE IRREVOCABLE IN ACCORDANCE WITH THE PROVISIONS OF
            SECTION 212 OF THE DELAWARE GENERAL CORPORATION LAW.

            5. CERTAIN EVENTS. The Stockholders agree that, except as provided
in Section 3, this Agreement and the obligations hereunder shall attach to the
Stockholders' Shares and shall be binding upon any person or entity to which
legal or beneficial ownership of such Shares shall pass, whether by operation of
law or otherwise, including without limitation the Stockholders' successors or
assigns. In the event of any stock split, stock dividend, merger,
reorganization, recapitalization or other change in the capital structure of
DSLN, or the acquisition of additional shares of DSLN Capital Stock or other
voting securities of DSLN by any Stockholder, the number of Shares subject to
the terms of this Agreement shall be adjusted appropriately and this Agreement
and the obligations hereunder shall attach to any additional shares of DSLN
Capital Stock or other voting securities of DSLN issued to or acquired by the
Stockholders.

            6. FURTHER ASSURANCES. The Stockholders shall, upon request of DSLN
or any of the Investors execute and deliver any additional documents and take
such further actions as may be necessary to carry out the provisions hereof and
to vest the power to vote each Stockholder's Shares as contemplated by Section 4
(except as provided in Section 3) in DSLN and the other irrevocable proxies
described therein at the expense of DSLN.

            7. TERMINATION. This Agreement, and all rights and obligations of
the parties hereunder, including, without limitation, the proxy set forth in
Section 4, shall terminate upon the first to occur of (i) the termination of the
Purchase Agreement in accordance with Section 1.5 thereof, or (ii) upon the
Second Closing (the "Termination Date").

                                        4

            8. MISCELLANEOUS.

                        (a) This Agreement may be executed in two or more
            counterparts (including by facsimile transmission), all of which
            shall be considered one and the same agreement.

                        (b) This Agreement (including the documents and
            instruments referred to herein) constitutes the entire agreement,
            and supersedes all prior agreements and understandings, both written
            and oral, among the parties with respect to the subject matter
            hereof.

                        (c) This Agreement shall be governed by, and construed
            in accordance with, the laws of the State of Delaware, regardless of
            the laws that might otherwise govern under applicable principles of
            conflicts of laws thereof.

                        (d) Neither this Agreement nor any of the rights,
            interests or obligations under this Agreement shall be assigned, in
            whole or in part, by operation of law or otherwise, by any of the
            parties without the prior written consent of the other parties. Any
            assignment in violation of the foregoing shall be void.

                        (e) The Stockholders agree that irreparable damage would
            occur and that DSLN and the Investors would not have any adequate
            remedy at law in the event that any of the provisions of this
            Agreement were not performed in accordance with their specific terms
            or were otherwise breached. It is accordingly agreed that DSLN and
            the Investors shall be entitled to an injunction or injunctions to
            prevent breaches by the Stockholders of this Agreement and to
            enforce specifically the terms and provisions of this Agreement,
            this being in addition to any other remedy to which they are
            entitled at law or in equity.

                        (f) If any term, provision, covenant or restriction
            herein, or the application thereof to any circumstance, shall, to
            any extent, be held by a court of competent jurisdiction to be
            invalid, void or unenforceable, such term, provision, covenant or
            restriction shall be modified or voided, as may be necessary to
            achieve the intent of the parties to the extent possible, and the
            remainder of the terms, provisions, covenants and restrictions
            herein and the application thereof to any other circumstances, shall
            remain in full force and effect, shall not in any way be affected,
            impaired or invalidated, and shall be enforced to the fullest extent
            permitted by law.

                        (g) No amendment, modification or waiver in respect of
            this Agreement shall be effective against any party unless it shall
            be in writing and signed by such party.
