may be charged to the Borrower's account and shall constitute Credit Advances.

amount shall either be applied, at the Lender's option, to the outstanding Loans
in such order as the Lender shall determine or refunded by the Lender to the
Borrower.

          (e) The Borrower shall pay principal, interest and all other amounts
payable hereunder, or under any Ancillary Agreement, without any deduction
whatsoever, including, but not limited to, any deduction for any set-off or

          (a) To secure the prompt payment to the Lender of the Obligations, the
Borrower hereby assigns, pledges and grants to the Lender a continuing security
interest in and to the Collateral, including a first lien on all unencumbered
Receivables, whether now owned or existing or hereafter acquired or arising and
wheresoever located, whether or not the same is subject to Article 9 of the UCC,
but not including any assets of any current or future Affiliate of Borrower
other than Receivables of Borrower. All of the Borrower's ledger sheets, files,
records, books of account, business papers and documents relating to the
Collateral shall, until delivered to or removed by the Lender, be kept by the
Borrower in trust for the Lender until all Obligations have been paid in full.
Each confirmatory assignment schedule or other form of assignment hereafter
executed by the Borrower shall be deemed to include the foregoing grant, whether
or not the same appears therein.

          (b) The Lender may, at its discretion, file one or more financing
statements disclosing the Lender's security interest in the Collateral without
the Borrower's signature appearing thereon or the Lender may sign on the
Borrower's behalf as provided in paragraph 11 herein. The parties agree that a
carbon, photographic or other reproduction of this Agreement shall be sufficient
as a financing statement. If any Receivable becomes evidenced by a promissory
note or any other instrument for the payment of money, the Borrower will
immediately deliver such instrument to the Lender appropriately endorsed.

     7. Covenants Concerning the Collateral. During the Term, the Borrower
covenants that it shall:

          (a) not dispose of any of the Collateral whether by sale, lease or
otherwise except for collection of the Collateral in the ordinary course of
business during any fiscal year; and to the extent that the amount of the Loan
exceeds the Maximum Loan Amount upon collection of the Collateral, the proceeds
of such Collateral shall be remitted to the Lender in reduction of the
Obligations;

          (b) not encumber, mortgage, pledge, assign or grant any security
interest in any of the Collateral to anyone other than the Lender;

          (c) keep and maintain the original and other documents evidencing, and
relating to, the agreements and transactions which gave rise to the Collateral,
including without limitation, all original orders and invoices;

create and maintain in the Lender's favor a valid perfected security interest in
all of the Collateral; and

                                        5

          (e) defend the Collateral against the claims and demands of all

Agreement, including, but not limited to, management letters prepared by
independent accountants, and (c) discuss with the Borrower's principal officers,

financial condition, results of operations and business prospects. The Borrower
will deliver to the Lender any instrument necessary for the Lender to obtain
records from any service bureau maintaining records for the Borrower.

     9. Financial Information The Borrower shall provide the Lender, no later
than two (2) business days following its I0-Q and 10-K filings under the
Securities Exchange Act of 1934, as amended, with the Securities and Exchange
Commission, a copy of the Borrower's financial statements that are included in
such filings. In addition, as soon as available and within 15 days after the end
of each month, the Borrower shall provide the Lender copies of Borrower's
consolidated balance sheet as of the end of such month, and the related
consolidated statements of income, shareholders' equity and cash flows for such
month and for the portion of the fiscal year ended with the last day of such
month.

     10. Representations, Warranties and Covenants. The Borrower represents,
warrants (each of which such representations and warranties shall be deemed
repeated upon the making of a request for a Credit Advance and made as of the
time of each Credit Advance made hereunder), and covenants that:

          (a) The Borrower is a corporation duly organized and validly existing

          (f) it will pay or discharge when due all taxes, assessments and

          (g) it will not (i) create, incur, assume or suffer to exist any
indebtedness (other than in the ordinary course) secured by the Collateral; (ii)

stock or preferred stock of the Borrower or apply any of its funds, property or
assets to the purchase, redemption or other retirement of any common or

credit to any Person;

          (h) it will bear the full risk of loss from any loss of any nature
whatsoever with respect to the Collateral. At it's own cost and expense in

Agreement, it shall (i) keep all its insurable properties and properties in
which it has an interest insured against the hazards of fire, flood, sprinkler

          (i) The Credit Advance will only be used for Borrower's working
capital or in connection with Avasta in accordance with Section 2(a) above,
provided, however, that on the Closing Date, the initial Credit Advance shall be
used to repay all outstanding indebtedness under the Original Agreement and the
Original Agreement shall be terminated as of such date and the Lender will be
provided with evidence satisfactory to it, including a copy of the cancelled
note; and

          (j) There is no Event of Default.

     11. Power of Attorney. The Borrower hereby appoints the Lender or any other
Person whom the Lender may designate as the Borrower's attorney, with power to

the Borrower. Lender shall provide copies of all such mail and its contents to
the Borrower. The Borrower hereby ratifies and approves all acts of the attorney
that are in accordance with this Section. Neither the Lender nor the attorney
will be liable for any acts or omissions that are in accordance with this
Section or for any error of judgment or mistake of fact or law. This power,
being coupled with an interest, is irrevocable so long as any receivable which
is assigned to the Lender or in which the Lender has a security interest remains
unpaid and until the Obligations have been fully satisfied.

                                        7

     12. Expenses. Each party shall pay all of its out-of-pocket costs and
expenses, including, without limitation, reasonable fees and disbursements of
counsel, in connection with the preparation, execution and delivery of this
Agreement and the Ancillary Agreements, and in connection with the prosecution
or defense of any action, contest, dispute, suit or proceeding concerning any
matter in any way arising out of, related to or connected with this Agreement or
any Ancillary Agreement. The Borrower shall pay the Lender's customary bank
charges for all bank services performed or caused to be performed by the Lender
for the Borrower at the Borrower's request or in connection with the Borrower's
loan account with the Lender. All such charges together with all filing,
recording and search fees, taxes and interest payable by the Borrower to the
Lender shall be payable on demand and shall be secured by the Collateral. If any
tax by any governmental authority is or may be imposed on or as a result of any
transaction between the Borrower and the Lender, which the Lender is or may be
required to withhold or pay, the Borrower agrees to indemnify and hold the
Lender harmless in respect of such taxes and the Borrower will repay to the
Lender the amount of any such taxes which shall be charged to the Borrower's
account; and until the Borrower shall furnish the Lender with indemnity therefor
(or supply the Lender with evidence satisfactory to it that due provision for
the payment thereof has been made), the Lender may hold without interest any
balance standing to the Borrower's credit and the Lender shall retain its
security interests in any and all of the Collateral.

     13. Assignment by Lender. The Lender may assign any or all of the
Obligations together with any or all of the security therefor and any transferee
shall succeed to all of the Lender's rights and duties with respect thereto as
set forth in this Agreement. Upon such transfer, the Lender shall be released
from all responsibility for the Collateral to the extent same is assigned to and
assumed by any transferee. The Lender may from time to time sell or otherwise
grant participations in any of the Obligations and the holder of any such
participation shall, subject to the terms of any agreement between the Lender
and such holder, be entitled to the same benefits as the Lender with respect to
any security for the Obligations in which such holder is a participant. The
Borrower agrees that each such holder may , in lieu of the Lender, exercise any
and all rights of the Lender's lien, set-off and counterclaim with respect to
its participation in the Obligations as fully as though the Borrower were
directly indebted to such holder in the amount of such participation.

     14. Waivers. The Borrower waives presentment and protest of any instrument
and notice thereof, notice of default and all other notices to which the
Borrower might otherwise be entitled.

effect until the expiration of the Term; provided, however, the Lender may
terminate at any time upon an Event of Default.

     16. Events of Default. The occurrence of any of the following shall
constitute an Event of Default upon which the unpaid principal amount of all
Credit Advances made hereunder, together with any accrued and unpaid interest,
fees and charges, and all other amounts owed to the Lender under this Agreement
shall automatically become immediately due and payable, all without presentment,
demand, notice, declaration, protest, or other requirements of any kind, all of
which are hereby expressly waived:

hereunder, in any Ancillary Agreement, any certificate, statement or document
delivered pursuant to the terms hereof, or in connection with the transactions
contemplated by this Agreement should at any time be false or misleading in any
material respect;

          (e) any lien created hereunder or under any Ancillary Agreement for
any reason ceases to be or is not a valid and perfected lien having a first
priority interest, unless solely due to the gross negligence of the Lender;

          (f) if pursuant to, or within the meaning of, the Bankruptcy Code or

trustee, examiner or liquidator of itself or of all or a substantial part of its
property;

conveys, or suffers or permits to occur any sale, assignment, transfer or
conveyance of any assets of the Borrower or any interest therein (including any
direct or indirect merger or consolidation of the Borrower) with any other
company, except (i) as permitted herein, (ii) in the ordinary course of
Borrower's business or (iii) the sale or disposition of old or obsolete
equipment, individually or in the aggregate, in an amount greater than $50,000;

     17. Remedies. The Lender has the right to demand repayment in full of all
of the Obligations pursuant to the terms of this Agreement, including upon the
occurrence of an Event of Default pursuant to paragraph 16 herein. Until all of
the Obligations have been fully satisfied, the Lender shall retain its security
interest in all of the Collateral. The Lender shall have, in addition to all
other rights provided herein, the rights and remedies of a secured party under
the UCC, and under other applicable law, all other legal and equitable rights to
which the Lender may be entitled, including, without limitation, the right to
take immediate possession of the Collateral, to require the Borrower to assemble
the Collateral, at the Borrower's expense, and to make it available to the
Lender at a place designated by the Lender that is reasonably convenient to both
parties and to enter any of the premises of the Borrower or wherever the
Collateral shall be located, with or without force or process of law, and to
keep and store the same on said premises until sold (and if said premises be the
property of the Borrower, the Borrower agrees not to charge the Lender for
storage thereof). Further, the Lender may, at any time or times after an Event
of Default by the Borrower, sell and deliver all of the Collateral held by or
for the Lender at public or private sale for cash, upon credit or otherwise, at
such prices and upon such terms as the Lender, in the Lender's sole discretion,
deems advisable or the Lender may otherwise recover upon the Collateral in any
commercially reasonable manner as the Lender, in its sole discretion, deems
advisable. The requirement of reasonable notice shall be met if such notice is
mailed postage prepaid to the Borrower at the Borrower's address as shown in the
Lender's records, at least ten (10) days before the time of the event of which
notice is being given. The Lender may be the purchaser at any sale, if it is
public. The proceeds of sale shall be applied first to all costs and expenses of
sale, including attorneys' fees, and second to the payment (in whatever order
the Lender elects) of all of the Obligations. The Lender will return any excess
to the Borrower and the Borrower shall remain liable to the Lender for any
deficiency.

     18. Waiver; Cumulative Remedies. Failure by the Lender to exercise any
right, remedy or option under this Agreement or any supplement hereto or any
other agreement between the Borrower and the Lender or delay by the Lender in
exercising the same, will not operate as a waiver, and no waiver by the Lender
will be effective unless it is in writing and then only to the extent
specifically stated. The Lender's rights and remedies under this Agreement will
be cumulative and not exclusive of any other right or remedy that the Lender may
have.

     19. Application of Payments. The Borrower irrevocably waives the right to
direct the application of any and all payments at any time or times hereafter
received by the Lender from or on the Borrower's behalf and the Borrower hereby
irrevocably agrees that the Lender shall have the continuing exclusive right to
apply and reapply any and all payments received at any time or times hereafter
against the Borrower's Obligations hereunder in such manner as the Lender may
deem advisable notwithstanding any entry by the Lender upon any of the Lender's
books and records.

     20. Notices. Any notice or request hereunder may be given to the Borrower
or the Lender at the respective addresses set forth below or as may hereafter be
specified in a notice designated as a change of address under this paragraph.
Any notice or request hereunder shall be given by registered or certified mail,
return receipt requested, hand delivery, overnight mail or telecopy (confirmed
by mail). Notices and requests shall be, in the case of those by hand delivery,
deemed to have been given when delivered to any officer of the party to whom it
is

Re:  400 Minuteman Road, Andover, Massachusetts (the "Property")

     Escrow # 2251-25171 with Chicago Title Insurance Company (the "Escrow")

     Closing Transactions Involving 400 River Limited Partnership ("River"),
     Farm Associates Limited Partnership ("Farm"), NaviSite, Inc. ("NaviSite"),
     and ClearBlue Technologies, Inc. ("ClearBlue") (collectively, the "Closing
     Transactions")

Dear Arthur:

As you and John Kusmiersky discussed, River and Farm (together, "Landlord"),
do not believe that the conditions to the "Closing Transactions" can be
satisfied before the end of the closing period on 1/31/2003. The "Closing
Transactions" and the conditions thereto and that closing period are described
in the Undertakings Agreement dated 9/11/2002 among River, Farm and ClearBlue
(as amended, the "Undertakings Agreement"), and the Letter Agreement dated
11/12/2002 among River, Farm, NaviSite and ClearBlue (the "Extension
Agreement").

We have the option of allowing the Closing Transactions to expire in accordance
with their terms assuming that the conditions thereto remain unsatisfied by
1/31/2003. Or, we can agree among ourselves now to terminate the Closing
Transactions, the Undertakings Agreement and the Escrow, in which case we will
promptly return to you ClearBlue's $2 Million Promissory Note that we are now
holding.

If you agree to terminate now, please arrange for ClearBlue and NaviSite to
promptly sign and return to me by fax a copy of this letter (please also send an
executed counterpart original by FedEx or the equivalent). When executed and
delivered by ClearBlue and NaviSite, this letter will serve to terminate the
Undertakings Agreement, the Extension Agreement, the Escrow and the obligations
thereunder without liability to any of the parties, and as instructions and
authorization to Chicago Title to terminate the Escrow and return the documents
it is holding in the Escrow to the depositing parties. All of the documents held
by Chicago Title in the Escrow, or to be delivered under Sections 7-12 of the
Undertakings Agreement, or to be delivered under the Extension Agreement, will
be deemed null and void, and it will be as if the conditions to the Closing
Transactions were unsatisfied as of the end of the closing period without
default of any party.

The existing agreements among the parties wi11 remain unaffected and in full
force and effect, including, without limitation, the existing Lease dated
5/14/1999, as amended, between River and NaviSite; the Guaranty of Lease dated

9/11/2002 made by Becker and Ruhan in favor of River, the letter agreement dated
November 12, 2002 between and among River, Farm, C1earBlue, NaviSite, Becker and
Ruhan regarding the transfer of the majority of the shares in NaviSite; and the
consents executed by River in favor of NaviSite and CMGI, Inc. on or about
