     indemnification, and upon surrender and cancellation of this Note, if
     mutilated, the Company will execute and deliver a new Note of like tenor
     and date. Any such new Note executed and delivered shall constitute an
     additional contractual obligation on the part of the Company, whether or
     not this Note so lost, stolen, destroyed, or mutilated shall be at any time
     enforceable by anyone.

          3. DEFAULT.

sell all or any of the Notes held by it (in integral multiples of $500,000),

securities" as defined under Article 8 of the Code) are "general intangibles" as
defined under Article 9 of the Code;

          3.9 Borrower's correct name, principal place of business and the
office where it keeps its records concerning the Pledged Interests is stated in
the caption hereof. In the event of any change in Borrower's principal place of
business, Borrower shall give Lender thirty (30) days' prior written notice of
such change. Borrower will hold and preserve such records (in accordance with
Borrower's usual document retention practices) and chattel paper and will

                                        3

<PAGE>

permit representatives of Lender upon reasonable advance notice (except if a
Default has occurred and is continuing in which event no such notice shall be
required) to have access to all premises of Borrower during normal business
hours to inspect and make abstracts from such records. In any suit, proceeding
or action brought by Lender against the Underlying Companies, Borrower shall
save, indemnify and keep Lender harmless from and against all expenses, loss or
damage suffered by reason of any defense, set off, counterclaim, recoupment or
reduction of liability whatsoever of the Underlying Companies thereunder,
arising out of a breach by Borrower of any obligation or arising out of any
other agreement, indebtedness or liability at any time owing to or in favor of
Lender from Borrower, and all such obligations of Borrower shall be and shall
remain enforceable against and only against Borrower and shall not be
enforceable against Lender; and

          3.10 No authorization, consent, approval or other action by, and no
notice to or filing with, any governmental authority, the Underlying Companies,
or any affiliate or subsidiary of the Underlying Companies, that have not
already been taken or made and which are in full force and effect, are required
(i) for the grant by Borrower of the security interest in and lien on the
Pledged Interests granted hereby; (ii) the execution, delivery or performance of
this Agreement by Borrower; or (iii) for the exercise by Lender of any of its
rights or remedies hereunder.

          3.11 Borrower covenants and agrees with Lender that, from and after
the date of this Agreement until the Obligations are paid in full, Borrower
will:

          (a) if Borrower shall, as a result of its ownership of the Pledged
Interests, become entitled to receive or shall receive any stock certificate,
limited liability company certificate or other certificated equity interest, as
applicable (including, without limitation, any certificate representing a
dividend or a distribution in connection with any reclassification, increase or
reduction of capital or any certificate issued in connection with any
reorganization), option or rights, whether in addition to, in substitution of,
as a conversion of, or in exchange for any Pledged Interests, or otherwise in
respect thereof, Borrower shall accept the same as Lender's agent, hold the same
in trust for Lender and deliver the same forthwith to Lender in the exact form
received, duly endorsed by the Borrower to Lender, if required, together with an
undated stock power, membership, partnership or limited liability company
interest power covering such certificate duly executed in blank and with, if
Lender so requests, signature guaranteed, to be held by Lender hereunder as
additional security for the Obligations. Any sums paid to Borrower upon or in
respect of the Pledged Interests upon the liquidation or dissolution of any
Underlying Company, and any distribution of capital made on or in respect of the
Pledged Interests or any property distributed upon or with respect to the
Pledged Interests pursuant to the recapitalization or reclassification of the
capital of any Underlying Company or pursuant to the reorganization thereof,
shall be used to immediately prepay the Loan. If any sums of money or property
so paid or distributed to the Borrower in respect of Pledged Interests shall be
received by Borrower, Borrower shall, until such money or property is paid or
delivered to Lender in order to prepay the Loan, hold such money or property in
trust for Lender, segregated from other funds of Borrower, as additional
security for the Obligations;

          (b) pay, and save Lender harmless from, any and all liabilities with
respect to, or resulting from any delay in paying, any and all stamp, excise,
sales or other taxes which may

                                        4

<PAGE>

be payable or determined to be payable with respect to any of the Pledged
Interests or in connection with any of the transactions contemplated by this
Agreement;

          (c) not (i) change its state of formation, (ii) change its name,
identity or structure to such an extent that any financing statement filed by
Lender in connection with this Agreement would become misleading within the
meaning of Section 9-506 of the Code, unless it shall have given Lender at least
thirty (30) days prior written notice thereof, or (iii) otherwise fail to
qualify as a "registered organization" (as defined in Section 9-102 of the Code)
organized under the laws of the State of Delaware; and

          (d) promptly (and in any event within five (5) Business Days), upon
obtaining ownership (by purchase, or exercise of any warrant, or option rights,
or stock dividend or otherwise) of any additional stock, partnership, limited
liability company, membership interests or other equity interests in an
Underlying Company that is otherwise required to be pledged to Lender pursuant
to any of the Loan Documents, which equity interests are not already Pledged
Interests, deliver to Lender a Pledge Amendment, duly executed by Borrower, in
substantially the form of Schedule D attached hereto (a "PLEDGE AMENDMENT") in
respect of such additional equity interests in an Underlying Company pursuant to
which Borrower shall pledge to Lender all of such additional equity interests.
Borrower hereby authorizes Lender to attach each Pledge Amendment to this
Agreement and agrees that all interests listed on any Pledge Amendment delivered
to Lender shall for all purposes hereunder be considered Pledged Interests.

     4. Voting; Receipt of Dividends. Unless a Default shall have occurred and
be continuing, Borrower shall be entitled to (a) vote any and all of the Pledged
Interests and to give consents, waivers or ratifications in respect thereof,
provided that no vote shall be cast or consent, waiver or ratification given or
action taken which would violate or be inconsistent with any of the terms of
this Agreement, the other Loan Documents or any other document or instrument
referred to in the Loan Documents or which would have the effect of impairing
the position or interests of Lender and (b) receive and retain all Dividends.
All such rights of Borrower to vote and to give consents, waivers and
ratifications, and to receive and retain Dividends, shall cease upon the
occurrence of, but only during the continuation of, a Default.

     5. Remedies Upon Default.

          5.1 After the occurrence and during the continuance of a Default,
Lender shall be entitled to exercise all of its rights, powers and remedies
(whether vested in it by this Agreement, the other Loan Documents or by law) for
the protection and enforcement of its rights in respect of the Pledged
Interests, and Lender shall be entitled, without limitation, to exercise the
following rights (in addition to the rights and remedies of a secured party
under the Code) which Borrower hereby agrees shall be commercially reasonable:

          (a) to vote all or any part of the Pledged Interests (whether or not
transferred into the name of Lender) and give all consents, waivers and
ratifications in respect of the Pledged Interests and otherwise act with respect
thereto as though it were the outright owner thereof (Borrower hereby
irrevocably constituting and appointing Lender, its employees, agents,
successors and assigns the proxy and attorney-in-fact of Borrower, with full
power of substitution to do the foregoing acts);

                                        5

<PAGE>

          (b) at any time or from time to time to sell, assign and deliver, or
grant options to purchase, all or any part of the Pledged Interests, or any
interest therein, at any public or private sale without demand of performance,
advertisement or notice of intention to sell or of the time or place of sale or
adjournment thereof or to redeem or otherwise, all of which are hereby waived by
Borrower, for cash, on credit or for other property, for immediate or future
delivery without any assumption of credit risk, and for such price or prices and
on such terms as Lender in its absolute discretion may determine, provided that
at least five (5) days' prior notice of the time and place of any such sale
shall be given to Borrower;

          (c) to ask, demand, collect, sue for, recover, compromise, receive and
give acceptance and receipts for moneys due and to become due under or in
respect of any of the Pledged Interests; receive, endorse, and collect any
drafts or other instruments, documents and chattel paper, in connection
therewith;

          (d) to file any claims or take any action or institute any proceedings
which Lender may deem necessary or desirable for the collection of any of the
Pledged Interests, or otherwise to enforce the rights of Lender with respect to
any of the Pledged Interests; and

          (e) to notify the Underlying Companies, at Borrower's expense, of the
security interests of Lender under this Agreement and direct that payments of
all amounts due or that become due in respect of the Pledged Interests therein
be made directly to Lender or its designee.

          Notwithstanding any provision herein to the contrary, upon the
occurrence of a Default, Lender may, at its option, at any time thereafter and
without notice to Borrower, exercise any and all rights pursuant to the terms of
the Loan Documents and shall receive the Proceeds of the Pledged Interests which
shall be applied in accordance with Section 7 hereof.

          5.2 If any of the Pledged Interests are sold by Lender upon credit or
for future delivery, Lender shall not be liable for the failure of the purchaser
to pay for the same and in such event Lender may resell such Pledged Interests.
Lender may buy any part or all of the Pledged Interests at any public sale and
if any part or all of the Pledged Interests are of a type customarily sold in a
recognized market or are of the type which are the subject of widely-distributed
standard price quotations, Lender may buy at a private sale and may make payment
therefor by any means including, without limitation, cancellation of
indebtedness secured thereby.

          5.3 Borrower recognizes that Lender may be unable to effect a public
sale of some or all of the Pledged Interests by reason of certain prohibitions
contained in the Securities Act of 1933, as amended, or in other applicable
laws, regulations, or agreements to which such Pledged Interests may be subject
but may be compelled to resort to one or more private sales thereof to a
restricted group of purchasers. Borrower agrees that any such private sales may
be at prices and other terms less favorable to the seller than if sold at public
sales and that such private sales shall be deemed to have been made in a
"commercially reasonable" maimer within the meaning of Section 9-610(b) of the
Code, provided that the notice specified in Section 5.1 hereof shall have been
given to Borrower. Lender shall be under no obligation to delay a sale of any
such Pledged Interests for the period of time necessary to permit the issuer of
such securities

                                        6

<PAGE>

to register such securities for public sale under the Securities Act of 1933, as
amended, even if the issuer would agree to do so.

          5.4 At any sale of the Pledged Interests, unless prohibited by
applicable law, Lender or any holder of the Obligations may bid for and purchase
all or any part thereof so sold free from any such right or equity of
redemption.

     6. Remedies Cumulative. Each right, power and remedy of Lender or any
holder of the Obligations provided for in this Agreement, the other Loan
Documents or in any of the other documents, instruments or agreements securing
the Obligations or now or hereafter existing at law or in equity or by statute
shall be cumulative and concurrent and shall be in addition to every other such
right, power or remedy. The exercise or beginning of the exercise by Lender or
any holder of the Obligations of any one or more of the rights, powers or
remedies provided for in this Agreement, the other Loan Documents or in any such
other document, instrument or agreement now or hereafter existing at law or in
equity or by statute or otherwise shall not preclude the simultaneous or later
exercise by Lender or any holder of the Obligations of all such other rights,
powers or remedies, and no failure or delay on the part of Lender or any holder
of the Obligations to exercise any such right, power or remedy shall operate as
a waiver thereof.

     7. Application of Moneys by Lender. All moneys collected upon any sale by
or on behalf of Lender of the Pledged Interests hereunder, together with all
other moneys received by Lender hereunder, shall be applied as follows: (i) to
the payment of all costs and expenses incurred by Lender in connection with such
sale, the delivery of the Pledged Interests or the collection of any such moneys
(including, without limitation, reasonable attorneys' fees and expenses); (ii)
to satisfy the Obligations; and (iii) to Borrower to the extent of any surplus
proceeds.

     8. Transfer By Borrower. Except as provided herein, Borrower will not sell
or otherwise dispose of, grant any option with respect to, or mortgage, pledge
(except pursuant to this Agreement or as otherwise permitted by the Loan
Documents) or otherwise encumber any of the Pledged Interests or any interest
therein or consent to or approve the issuance of any additional stock
certificates, partnership or membership interests in the Underlying Companies,
or any securities convertible voluntarily by the holder thereof or automatically
upon the occurrence or nonoccurrence of any event or condition into, or
exchangeable for, any such partnership or membership interests, or any warrants,
options, rights, or other commitments entitling any person to purchase or
otherwise acquire any such stock certificates, partnership or membership
interests.

     9. Borrower's Obligations Absolute. The obligations of Borrower under this
Agreement shall be absolute and unconditional and shall remain in full force and
effect without regard to, and shall not be released, suspended, discharged,
terminated or otherwise affected by any circumstance or occurrence whatsoever,
including, without limitation: (a) any renewal, extension, amendment or
modification of or addition or supplement to or deletion from the other Loan
Documents, or any document, instrument or agreement referred to therein, or any
assignment or transfer of the other Loan Documents or any such other document,
instrument or agreement; (b) any waiver, consent, extension, indulgence or other
action or inaction under or in respect of the Loan Documents or any such other
document, instrument or agreement; (c) any

                                        7

<PAGE>

furnishing of any additional security to Lender or its assignees or any
acceptance thereof or any release of any security by Lender or its assignees,
including, without limitation, partial releases; (d) any limitation on any
party's liability or obligations under the Loan Documents or any such other
document, instrument or agreement or any invalidity or unenforceability, in
whole or in part, of the same; or (e) any bankruptcy, insolvency,
reorganization, composition, adjustment, dissolution, liquidation or other like
proceeding relating to Borrower or the other Underlying Companies, or any action
taken with respect to this Agreement by any trustee or receiver or by any court,
in any such proceeding; whether or not Borrower or the other Underlying
Companies shall have notice or knowledge of any of the foregoing.

     10. Further Assurances. Borrower at its expense will execute, acknowledge
and deliver all such instruments and take all such action as Lender from time to
time may reasonably request in order to further effectuate the purposes of this
Agreement and to carry out the terms hereof. In furtherance of the foregoing,
Borrower hereby irrevocably appoints Lender as its attorney-in-fact, with full
authority in the place and stead of Borrower and in the name of Borrower or
otherwise, from time to time in Lender's discretion, to execute, acknowledge and
deliver all such instruments and take all such actions, including, without
limitation, the filing of one or more financing or continuation statements under
the Code, to perfect Lender's security interest in the Pledged Interests.

     11. Lender's Exoneration. Under no circumstances shall Lender be deemed to
assume any responsibility for or obligation or duty with respect to any part or
all of the Pledged Interests of any nature or kind (including, without
limitation, under any of the Underlying Company's organizational documents and
any other agreements or instruments evidencing or relating to the Pledged
Interests), or any matter or proceedings arising out of or relating thereto, but
the same shall be at Borrower's sole risk at all times, except in connection
with acts of gross negligence or willful misconduct as determined in a final
judgment of a court of law. Notwithstanding the pledge and security interest
granted herein or the exercise by Lender of its rights and remedies hereunder,
Borrower shall remain liable and not be released from its obligations under the
Underlying Companies' organizational documents and any other agreements or
instruments evidencing or relating to the Pledged Interests. Lender shall not be
required to take any action of any kind to collect, preserve or protect its or
Borrower's rights in the Pledged Interests or against other parties thereto.
Lender may exercise any or all of the rights and remedies available to it under
this Agreement, the other Loan Documents and applicable law in any order, manner
or combination which Lender shall determine, and therefore Lender shall not be
required to exercise its rights or remedies with respect to any part or all of
the Pledged Interests prior to making any demand, or instituting any suit or
proceeding for payment or collection of the Obligations.

     12. No Waiver, Etc. Lender may exercise its rights with respect to the
Pledged Interests without resorting or regard to other collateral or sources of
reimbursement. Lender shall not be deemed to have waived any of its rights upon
or under the Obligations or the Pledged Interests unless such waiver is in
writing and signed by Lender. No delay or omission on the part of Lender in
exercising any right under this Agreement shall operate as a waiver of such
right or any other right. A waiver on any one occasion shall not be construed as
a bar to or waiver of any right on any future occasion. All rights and remedies
of Lender on the Obligations or the Pledged

                                        8

<PAGE>

Interests, whether evidenced hereby or by any other instrument or papers, shall
be cumulative and may be exercised separately or concurrently.

     13. Termination. At such time as the Obligations have been paid in full,
this Agreement shall terminate and Lender, at the expense of Borrower, will duly
assign, transfer and deliver to Borrower, or its successors or assigns, as the
case may be, such of the Pledged Interests and the certificates representing
such interests as have not theretofore been sold or otherwise applied or
released pursuant to this Agreement.

     14. Miscellaneous.

          14.1 Successors and Assigns. This Agreement shall inure to the benefit
of and shall be binding upon the parties hereto and their respective successors
and assigns whether or not an express assignment of rights hereunder is made. No
other person shall acquire or have any right under or by virtue of this
Agreement.

          14.2 Provisions to Survive. All representations, warranties, covenants
and agreements contained in this Agreement shall survive the execution and
delivery of the Loan Documents and shall continue until payment in full of the
Obligations.

          14.3 Severability. The invalidity or unenforceability of any one or
more provisions of this Agreement or any other Loan Document in its entirety or
under particular circumstances shall not affect the validity or enforceability
of such provisions under different circumstances or the validity or
enforceability of any other provision.

          14.4 Amendments. This Agreement may be amended, modified and
supplemented only by written agreement of the parties hereto.

          14.5 Execution and Counterparts; Facsimile. This Agreement maybe
executed in several counterparts, each of which shall be deemed an original
enforceable against the signatory thereto and all of which shall constitute one
and the same instrument. This Agreement constitutes the entire agreement and
understanding among the parties hereto and supersedes any and all prior or
contemporaneous agreements and understandings, oral or written, relating to the
subject matter hereof. A facsimile of an original signature on any document or
instrument, including this Agreement, shall be deemed an original signature for
all purposes.

          14.6 Captions. Captions and headings in this Agreement are for
convenience only and in no way define, limit or describe the scope or intent of
the provisions hereof.

          14.7 Notices. All notices, certificates or other communications
hereunder shall be in writing and shall be sufficiently given and shall be
deemed given when given in the manner set forth in Section 11(g) of the Note.

          14.8 Governing Law and Jurisdiction. This Agreement shall be governed
by, and construed in accordance with, the laws of the State of Massachusetts
without regard to principles of conflicts of laws.

                                        9

<PAGE>

          14.9 Lender May Perform. If Borrower fails to perform any agreement
contained herein, Lender may, without notice to Borrower, perform, or cause
performance of, such agreement, and the reasonable expense of Lender incurred in
connection therewith shall be payable by Borrower.

          14.10 Powers of Attorney. It is hereby acknowledged that each power of
attorney granted hereunder is coupled with an interest. Borrower hereby
irrevocably appoints Lender as Borrower's attorney-in-fact, with full authority
in the place and stead of Borrower and in the name of Borrower or otherwise,
from time to time in Lender's discretion, to take any action and to execute any
instrument which Lender may deem necessary or advisable to accomplish the
purposes of this Agreement, including, without limitation, in connection with
the exercise of the rights and remedies granted to Lender under Section 5
hereof.

          14.11 Revival of Security Interests. To the extent that Borrower makes
a payment or other transfer to Lender or Lender receives any payment of Proceeds
of the Pledged Interests, which is later invalidated, declared to be a
fraudulent transfer or preference, set aside or required to be repaid under any
bankruptcy law, other law or equitable principle, Lender's security in the
Pledged Interests shall be revived and continue as if the payment, transfer or
Proceeds had never been received by Lender.

          14.12 Specific Performance Remedies Cumulative. The parties hereby
agree with each other that, in the event of any breach of this Agreement by any
party where such breach may cause irreparable harm to any other party, or where
monetary damages may not be sufficient or may not be adequately quantified, then
the affected party or parties shall be entitled to specific performance,
injunctive relief or such other equitable remedies as may be available to it,
which remedies shall be cumulative and non-exclusive, and in addition to such
other remedies as such party may otherwise have at law or in equity.
