   NEITHER THIS SECURITY NOR ANY SECURITY ISSUABLE UPON CONVERSION HEREOF HAS
 BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE
      STATE SECURITIES LAWS AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED,

                                 NAVISITE, INC.

                                 PROMISSORY NOTE
                                  (ESCROW NOTE)

Principal Amount:  [$____________]                                  May __, 2004

      FOR VALUE RECEIVED, the undersigned, NAVISITE, INC., a Delaware
corporation ("NAVISITE"), and each Principal Subsidiary (as defined below) which
is a signatory hereto (NaviSite and such Principal Subsidiaries, collectively,
and jointly and severally, the "COMPANY"), hereby unconditionally promise,
jointly and severally, to pay to the order of SUREBRIDGE, INC. (together with
its successors and/or permitted assigns, the "HOLDER"), in lawful money of the
United States of America and in immediately available funds, the principal
amount of [___________________ UNITED STATES DOLLARS ($_______________)],
together with all accrued and unpaid interest thereon (and any unpaid penalties,
fees, costs or expenses due the Holder hereunder) on this Note.

      The undersigned further agree, jointly and severally, to pay interest as
provided below at the Holder's address referred to below on the unpaid balance
of this Note at the rates per annum and on the dates specified below until paid
in full. Subject to the provisions of the Purchase Agreement (as defined below),
all payments hereunder shall be made for the account of Holder at such Holder's
address, or if the Holder is Surebridge, Inc., to Surebridge, Inc., c/o Spectrum
Equity Investors, One International Place, Boston, MA 02110, or in any case to
such other address as the Holder may designate in accordance with the terms of
Section 14 hereof. If any principal of, or interest on, this Note is not paid
when due or there exists an Event of Default, certain additional interest may be
payable on this Note in accordance with the provisions hereof.

      This Note and the Primary Note (as herein defined) are being issued to the
Holder in connection with that certain Asset Purchase Agreement, dated as of May
6, 2004 (as amended, supplemented or otherwise modified from time to time, the
"Purchase Agreement"), among Surebridge, Inc., Lexington Acquisition Corp. and
NaviSite. The Purchase Agreement, the Registration Rights Agreement (as defined
in the Purchase Agreement) providing for the
<PAGE>
registration of the Parent Shares (as defined in the Purchase Agreement), the
Primary Note and this Note are collectively referred to herein as the
"TRANSACTION DOCUMENTS").

      ALL OBLIGATIONS OF THE COMPANY HEREUNDER ARE AND SHALL BE FOR ALL PURPOSES
HEREUNDER AND OTHERWISE THE JOINT AND SEVERAL OBLIGATIONS OF NAVISITE AND ITS
PRINCIPAL SUBSIDIARIES SIGNATORIES HERETO.

1.    Principal Repayment; Mandatory Prepayment.

      The original principal amount of this Note is [$__________]. The original
principal amount is subject to adjustment as set forth in the Purchase
Agreement. This Note shall be surrendered to the Company at such time as any
such adjustments are finally determined and the Company shall cancel this Note
and shall prepare and issue a new replacement note with all terms and provisions
identical to the terms hereof, other than with respect to the principal amount
of the note and with respect to this sentence and the immediately preceding
sentences, both of which sentences shall be omitted from the replacement note.
The Company shall repay the outstanding principal of this Note, together with
all interest accrued thereon and other amounts due in respect thereof on [May
__], 2006 (the "MATURITY DATE").

      After the date hereof, the Company shall prepay all or part of the
outstanding principal balance of this Note and the Primary Note, together with
all interest accrued and unpaid thereon, and any other amounts due with respect
thereto in an amount equal to seventy-five percent (75%) of all Net Cash
Proceeds (as defined below) within three business days of receipt of Net Cash
Proceeds by the Company (a "MANDATORY PREPAYMENT"). Such Mandatory Prepayment
shall be pro rated between this Note and the Primary Note based on the total
principal outstanding under both Notes. Payments in respect of this Note shall
be applied, first, to interest accrued and unpaid on the outstanding principal
of this Note and, second, to prepay the principal amount of this Note.
Notwithstanding the foregoing, during the period when the Working Capital
Adjustment is not resolved under Section 1.6 of the Purchase Agreement, and
NaviSite would otherwise be obligated to pay this Note in full as a Mandatory
Prepayment, NaviSite may retain up to $500,000 of the amount otherwise payable
until such time as the Net Working Capital Adjustment is resolved under the
Purchase Agreement.

      2.    Optional Prepayment.

      The Company may prepay all or any part of the unpaid principal of this
Note and the Primary Note, together with all accrued and unpaid interest thereon
and other amounts due in respect thereof, at any time and from time to time
without premium or penalty, provided that in connection with any such
prepayment, the Company, at the Holder's request, shall provide the Holder,
within a reasonable time after receipt of Holder's request, with evidence
reasonably satisfactory to the Holder that such prepayment is not prohibited
under the Company's other outstanding Indebtedness. Other than a prepayment
required by Section 5.22 of the Purchase Agreement, such prepayment shall be pro
rated between this Note and the Primary Note based on the total principal then
outstanding under both Notes. Payments in respect of this Note shall be applied,
first, to interest accrued and unpaid on the outstanding principal of this Note
and, second, to repay the principal amount of this Note.

                                       2
<PAGE>
3.    Interest.

      Interest shall accrue on the unpaid balance of this Note at the annual
rate of ten percent (10%), and shall be paid in full on the Maturity Date (or
such earlier date as provided herein); provided, however, that if an Event of
Default (as defined below) shall occur and be continuing, all principal and
interest outstanding under this Note shall, as of and after the occurrence of
such Event of Default, bear interest at a rate per annum of fifteen percent
(15%). Interest on this Note shall be computed based on a 360-day year of twelve
30-day months. Notwithstanding the foregoing or anything to the contrary, no
interest shall be due or payable and no interest shall accrue on account of any
principal amount paid to the Holder on or prior to the six month anniversary of
the issuance date of this Note.

4.    Event of Default.

      If any of the following shall occur (each an "EVENT OF DEFAULT"):

      (a) all or any portion of the principal of, or interest on, or other
amounts payable with respect to this Note is not paid when due, and such failure
continues for three business days after receipt of written notice thereof from
the Holder or a holder hereof; or

      (b) there shall have been a material breach by NaviSite of Section 4.10 of
the Purchase Agreement; or

      (c) a proceeding under 11 U.S.C. Sections 101 et seq., as amended,
and any similar or successor Federal statute, and the rules and regulations
thereunder (collectively, the "BANKRUPTCY CODE"), seeking an order for relief or
under any other bankruptcy, reorganization, arrangement of debt, insolvency,
readjustment of debt or receivership law or statute is filed against NaviSite or
any Principal Subsidiary and such proceeding is not dismissed within 60 days of
the date of its filing, or a proceeding under the Bankruptcy Code seeking an
order for relief or under any bankruptcy, reorganization, arrangement of debt,
insolvency, readjustment of debt or receivership law or statute is filed by
NaviSite or any Principal Subsidiary, or NaviSite or any Principal Subsidiary
makes an assignment for the benefit of creditors, or NaviSite or any Principal
Subsidiary authorizes any of the foregoing; or

      (d) NaviSite or any Principal Subsidiary voluntarily or involuntarily
dissolves or is dissolved, or its existence terminates or is terminated (other
than following a merger by any Principal Subsidiary with and into another
Principal Subsidiary or with or into NaviSite) unless NaviSite or such Principal
Subsidiary revives its certificate of incorporation within three business days
thereafter; or

      (e) NaviSite or any Principal Subsidiary fails generally to pay its debts
as they become due; or

      (f) NaviSite or any Principal Subsidiary fails to pay any principal of or
interest on any Debt for Borrowed Money (for purposes of clarity only, such Debt
for Borrowed Money shall not include Capitalized Leases (as defined herein))
having an outstanding principal amount of $500,000 or more ("MATERIAL
INDEBTEDNESS") for a period, with respect to the SVB Line, longer than the grace
or cure period, if any, provided for such payment, or with respect to any

                                       3
<PAGE>
other Material Indebtedness for a period longer than 120 days after the
applicable grace or cure period, if any, provided for such payment; an event of
default is declared under any instrument or agreement evidencing, creating,
securing or otherwise relating to such Material Indebtedness (including without
limitation any guaranty or assumption agreement relating to such Material
Indebtedness) or other event occurs and continues beyond any applicable grace
period, and the effect of such default or other event is to cause, or to permit
the holder or holders of such Material Indebtedness (or their representative) to
cause, such Material Indebtedness (or the obligations under any such guaranty or
assumption agreement) to become due and payable prior to the stated maturity
thereof; or

      (g) NaviSite shall fail to maintain the listing or quotation of its common
stock on the Nasdaq SmallCap Market (unless it obtains a listing or quotation of
its common stock on the Nasdaq National Market or the American Stock Exchange);
or

      (h) NaviSite shall breach any of its covenants contained in Section 5 or
Section 9 hereof; or

      (i) NaviSite shall fail to perform its obligations under Sections 1, 2 or
6 of the Registration Rights Agreement, unless such failure to perform is the
result of actions or omissions by Surebridge; or

      (j) NaviSite shall be acquired or agree to be acquired (which for purposes
hereof, shall mean the acquisition by any party of (i) more than 50% of the
stock or (ii) all or substantially all of the assets of NaviSite) (whether by
merger, consolidation, sale of all or substantially all of its assets or
otherwise) and in connection with such transaction the acquiring party does not
expressly agree in writing to pay the remaining outstanding principal and
accrued interest hereunder or otherwise assume and honor the terms and
provisions of this Note;

then, in any such case, upon the delivery of written notice to NaviSite (subject
to any grace or cure periods identified above) in the manner provided in Section
14 below, the Holder may declare due and payable the principal of, interest on
and other amounts due in respect of, this Note, whereupon the same shall be
immediately due and payable; provided, however, if an Event of Default of the
type described in the preceding clauses (c) or (d) shall occur, then the
principal of, interest on and other amounts due in respect of, this Note shall
be, without any action on the part of the holder hereof, automatically due and
payable immediately upon the occurrence of such an Event of Default. In the
event that this Note becomes or is declared due and payable prior to its stated
maturity, the same shall become due and payable without presentment, demand,
protest or other notice of any kind, all of which are hereby expressly waived.

5.    Covenants.

      (a) Priority of Obligations; Incurrence of Indebtedness. For so long as
any principal shall be outstanding hereunder, or any interest or other amounts
due with respect hereto, shall be outstanding, the Company shall not incur, and
shall not commit itself to, or permit or suffer any of its Subsidiaries to incur
or to commit to incur consolidated (as defined below) Indebtedness (including,
without limitation assume, guarantee, endorse or otherwise be or become
directly, indirectly or contingently liable for Indebtedness of any other
Person) that, together with all

                                       4
<PAGE>
other consolidated Indebtedness of the Company exceeds (or would exceed if so
incurred) $20,500,000 in the aggregate (the "WORKING CAPITAL INDEBTEDNESS"),
unless (i) such Indebtedness is unsecured and expressly subordinated by its
terms, to the reasonable satisfaction of the Holder, to the prior indefeasible
payment in full in cash of this Note, including the principal hereof, interest
accrued thereon and other amounts payable with respect hereto; (ii) such
Indebtedness is Excluded Indebtedness (as defined below); or (iii) the proceeds
of such Indebtedness are used to make a Mandatory Prepayment hereunder.
Notwithstanding the foregoing, if the Company pays any portion of the
outstanding principal balance under the Primary Note and the Primary Note prior
to the Maturity Date as a Mandatory Prepayment or otherwise, the Working Capital
Indebtedness which is equal to or senior with the indebtedness hereunder that
the Company shall be authorized to incur shall be increased by an amount equal
to all Mandatory Prepayment installments and other payments made by the Company
pursuant hereto. For purposes of this Section 5(a), "EXCLUDED INDEBTEDNESS"
shall mean (i) any indebtedness outstanding under this Note or the Primary Note;
(ii) any Capitalized Lease obligations of the Company; (iii) the outstanding
unsecured Indebtedness that is identified on SCHEDULE A attached hereto; and
(iv) any promissory note entered into with any of the Company's or its
subsidiaries' landlords, in each case not affiliated with the Company, solely as
part of restructuring of a real estate lease obligation.

      (b) Financial Reporting. Upon written request of a Holder, NaviSite shall
provide to the Holder a copy of all financial and other information provided to
all stockholders of NaviSite concurrently with providing such information to its
stockholders. The financial statements of NaviSite and the related notes
contained in the Public Filings (as defined in the Purchase Agreement) will
present fairly, in accordance with generally accepted accounting principles
(except for the absence of notes, and in the case of unaudited quarterly
financial statements, as permitted by Regulation S-X) the consolidating
financial position of NaviSite as of the dates indicated, and the results of its
operations and cash flows for the periods therein specified (subject in the case
of unaudited financial statements to normal year-end audit adjustments). Such
financial statements (including the related notes) will be prepared in
accordance with generally accepted accounting principles applied on a consistent
basis throughout the periods therein specified, except as disclosed in the
Public Filings.

      (c) Continued Listing. NaviSite will comply with the continued listing
requirements of the Nasdaq Marketplace Rules and will take no action designed
to, or which to its knowledge is likely to have the effect of, terminating the
registration of its common stock under the Exchange Act of 1934 or delisting the
common stock from the Nasdaq SmallCap Market (unless it obtains a listing or
quotation of its common stock on the Nasdaq National Market or the American
Stock Exchange).

      (D) RULE 145. THE HOLDER COVENANTS, FOR PURPOSES OF AND WITHIN THE MEANING
OF RULE 145 UNDER THE SECURITIES ACT OF 1933, AS AMENDED, THAT FOR ONE (1) YEAR
AFTER THE DATE HEREOF, THE HOLDER AND THE HOLDER'S BOARD OF DIRECTORS WILL NOT:
(A) DISTRIBUTE THIS NOTE OR ANY INTERESTS HEREUNDER PRO RATA OR OTHERWISE TO ITS
SECURITYHOLDERS; (B) ADOPT A PLAN OR AGREEMENT THAT PROVIDES FOR DISSOLUTION OR
LIQUIDATION OF THE HOLDER; OR (C) ADOPT A PLAN OR

                                       5
<PAGE>
AGREEMENT THAT PROVIDES FOR A PRO RATA OR SIMILAR DISTRIBUTION OF THIS NOTE TO
THE SECURITYHOLDERS OF THE HOLDER OR OTHERWISE.

6.    Acknowledgment. The Holder acknowledges, understands and agrees that in no
      event shall this Note and the Primary Note collectively be convertible
      into an aggregate number of shares of NaviSite's Common Stock that is
      equal to or greater than the Share Cap (as defined in the Purchase
      Agreement) unless and until NaviSite has obtained the effective approval
      of its stockholders of those matters described in Section 5.18 of the
      Purchase Agreement.

7.    Legends.

The Holder hereby acknowledges that this Note (unless no longer required in the
opinion of counsel, which opinion and counsel shall be reasonably satisfactory
to the Company, it being agreed that Goodwin Procter LLP shall be satisfactory)
shall bear legends substantially in the following forms:

            THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
            1933, AS AMENDED, OR ANY APPLICABLE STATE SECURITIES LAWS AND MAY
            NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE
            TRANSFERRED WITHOUT COMPLIANCE WITH THE REGISTRATION OR
            QUALIFICATION PROVISIONS OF APPLICABLE FEDERAL AND STATE SECURITIES
            LAWS OR APPLICABLE EXEMPTIONS THEREFROM.

            IN NO EVENT SHALL THIS PROMISSORY NOTE NOR ANY INTEREST HEREIN OR
            HEREUNDER BE ASSIGNED, CONVEYED, ENCUMBERED, PLEDGED, SOLD,
            DISTRIBUTED OR OTHERWISE TRANSFERRED UNTIL AFTER THE FIRST
            ANNIVERSARY OF THE DATE OF THIS PROMISSORY NOTE.

8.    No Impairment; Obligations Absolute.

      The obligations hereunder of NaviSite and each of the Principal
Subsidiaries shall remain in full force and effect without regard to, and shall
not be impaired by, (A) any bankruptcy, insolvency, reorganization, arrangement,
readjustment, composition, liquidation or the like of NaviSite or any Principal
Subsidiary; (B) any exercise or non-exercise, or any waiver of, any right,
remedy, power or privilege under or in respect of this Note; or (C) any
amendment to this Note, whether or not NaviSite or any Principal Subsidiary
shall have notice or knowledge of any of the foregoing. The obligations of
NaviSite and each Principal Subsidiary are independent of any other obligations
of NaviSite under or in respect of the Purchase Agreement, and a separate action
or actions may be brought and prosecuted against NaviSite or any Principal
Subsidiary to enforce this Note, irrespective of whether any action is brought
against NaviSite under or in respect of the Purchase Agreement. All rights of
the Holder shall be irrevocable, absolute and unconditional irrespective of, and
NaviSite and each Principal Subsidiary hereby irrevocably waives (to the maximum
extent permitted by applicable law) any defenses it may now have or may
hereafter acquire in any way relating to, any or all of the following: (a) any
lack of validity

                                       6
<PAGE>
or enforceability of the Purchase Agreement or any other agreement or instrument
relating thereto; (b) any change in the time, manner or place of payment of, or
in any other term of, all or any obligations of NaviSite under or in respect of
the Purchase Agreement or any other amendment or waiver of or any consent to any
departure therefrom; (c) any change, restructuring or termination of the
corporate structure or existence of NaviSite or any Principal Subsidiary; or (d)
any other circumstance or any existence of or reliance on any representation by
the Holder or any other holder that might otherwise constitute a defense
available to, or a discharge of, NaviSite or any Principal Subsidiary.

9.    Conversion.

      The outstanding principal of this Note, all accrued and unpaid interest
thereon and other amounts in respect thereto shall be converted, if the Holder
so elects, into NaviSite common stock, par value $0.01 per share (the "COMMON
STOCK") in accordance with this Section 9.

      Subject to any express grace or cure periods set forth herein, upon the
written election of the Holder and without payment of any additional
consideration, this Note shall be converted into such whole number of fully paid
and nonassessable shares of Common Stock as is determined by dividing (A) all or
a portion, as elected by the Holder, of the then outstanding principal of this
Note, accrued and unpaid interest thereon, and any other amounts due in respect
thereto by (B) $____________, [AVERAGE CLOSING PRICE FOR THE TEN TRADING DAYS
ENDING ONE DAY PRIOR TO CLOSING] (such formula, the "CONVERSION FORMULA"), with
such Conversion Formula to be appropriately adjusted to account for stock
dividends, stock splits, reverse stock splits, stock combinations or other
events. No fractional shares shall be issued, and the number of shares resulting
from the Conversion Formula shall be rounded down to the nearest whole share.
Any election by the Holder pursuant to this Section 9 shall be made by written
notice to NaviSite, and such notice may be given:

      (a) at any time following the first anniversary of the date hereof until
the eighteen (18) month anniversary hereof if the combined principal amount of
the Primary Note and the Escrow Note then outstanding as of the first
anniversary is greater than or equal to $20,000,000;

      (b) at any time following the eighteen (18) month anniversary hereof if
the combined principal amount of the Primary Note and the Escrow Note
outstanding as of said date is greater than or equal to $10,000,000;

      (c) at any time and from time to time after the second anniversary hereof;
or

      (d) after the occurrence of an Event of Default, provided that if such
Event of Default occurs prior to the effectiveness of the stockholder's approval
contemplated by Section 5.18 of the Purchase Agreement, then this Note and the
Primary Note collectively shall not be convertible into a number of shares of
NaviSite's Common Stock that is equal to or greater than the Share Cap unless
and until NaviSite has obtained the effective approval of its stockholders of
those matters described in Section 5.18 of the Purchase Agreement.

      Notwithstanding the foregoing, in the event the Holder desires to convert
pursuant to Section 9(a) or 9(b), NaviSite may, within 5 days of receipt of the
Holder's Conversion Notice, notify the Holder of its good faith intent to pay,
within 30 days of NaviSite's receipt of the

                                       7
<PAGE>
Conversion Notice, to the Holder an amount that would cause the $20,000,000
threshold in Section 9(a) or the $10,000,000 threshold in Section 9(b), as
applicable, to be satisfied if such payment had been made on the applicable
anniversary date. In such event, a Holder may only convert pursuant to Section
9(a) or 9(b), as applicable, in the 5 business day period following receipt of
NaviSite's notice of its intent to pay. If the Holder does not convert, the
restriction on conversion set forth in the previous sentence shall expire on the
earlier to occur of (i) receipt from NaviSite of notice that it will not be able
to pay such amounts and (ii) 30 days after NaviSite's receipt of the Conversion
Notice. NaviSite shall act in good faith to promptly deliver the notice in
clause (i) above in the event it becomes reasonably apparent to NaviSite that
NaviSite will not be able to pay such amount in the 30 day period.

      Upon election to convert, the Holder shall surrender this Note, duly
assigned or endorsed for transfer to NaviSite or shall deliver an affidavit of
loss to NaviSite (together with an agreement to indemnify NaviSite in full with
respect to any loss actually incurred with respect to the lost Note), at its
principal executive office or such other place as NaviSite may from time to time
designate by notice to the Holders. Upon surrender of this Note or delivery of
an affidavit of loss (together with an agreement to indemnify NaviSite in full
with respect to any loss actually incurred with respect to the lost Note),
NaviSite shall commence the issuance of, and shall send by hand delivery, by
courier or by first class mail (postage prepaid) to the Holder, or to the
Holder's designee, at the address designated by the Holder, certificates for the
number of shares of Common Stock to which the Holder shall be entitled upon
conversion. The issuance of certificates for Common Stock upon conversion of
this Note shall be deemed effective as of the date of surrender of this Note or
delivery of such affidavit of loss (together with an agreement to indemnify
NaviSite in full with respect to any loss actually incurred with respect to the
lost Note) and will be made without charge to the holder of this Note for any
issuance tax in respect thereof or other costs incurred by NaviSite in
connection with such conversion and the related issuance of such stock. In the
event that the Holder elects to convert pursuant to this Section 9 less than all
of the then outstanding principal of this Note, accrued and unpaid interest
thereon, and any other amounts due in respect thereto, the Company shall issue a
replacement note with the same terms as this Note and a principal equal to the
amount of principal, interest and other amounts not converted into Common Stock
by the Holder.

      NaviSite shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of
effecting the conversion of this Note as provided hereunder, such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of this Note as provided hereunder; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of this Note as provided hereunder, NaviSite will take such
corporate action as may be necessary to increase the number of its authorized
but unissued shares of Common Stock to such number of shares as shall be
sufficient for such purpose, and to reserve the appropriate number of shares of
Common Stock for issuance upon such conversion.

      NaviSite and the Holder shall act in good faith in the performance of
their respective covenants hereunder.

                                       8
<PAGE>
10.   No Waivers; Amendments.

      No failure or delay on the part of the Holder or NaviSite in exercising
any right, power or remedy hereunder or under the Purchase Agreement or any
other document executed in connection therewith shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right, power or
remedy preclude any other or further exercise thereof or the exercise of any
other right, power or remedy. The remedies provided for herein and in the
Purchase Agreement and the Registration Rights Agreement are cumulative and are
not exclusive of any remedies that may be available to the Holder at law or in
equity or otherwise.

      Subject to the provisions of Section 11 below on the effect of an
assignment of this Note, this Note may not be amended except by a writing duly
executed and delivered by the Holder (or, if more than one Holder, by those
Holders holding greater than fifty percent (50%) of the total then outstanding
principal amount hereunder) and NaviSite.

11.   Assignment; Lost Note, etc.

      Subject to Holder's compliance with federal and state securities laws to
the reasonable satisfaction of counsel for the Company, after the first
anniversary of the date hereof, the Holder may, prior to maturity or prepayment
thereof, assign all or a portion of this Note, in connection with the
liquidation of the Holder or otherwise, to each stockholder or Affiliate of the
Holder. Prior to such assignment, the Holder shall deliver an opinion of counsel
(which opinion and counsel shall be reasonably satisfactory to the Company, it
being agreed that Goodwin Procter LLP shall be satisfactory) to the effect that
such assignment is exempt from the registration requirements of the Securities
Act of 1933.

      Automatically, upon any assignment of the Note in whole or in part:

      (a) Each reference to "the Holder" shall mean and be a reference to each
assignee holder and all assignee holders, and their successors and assigns;

      (b) Each reference to "the Note" or "this Note" shall mean and be a
reference to each replacement Note and all the Notes issued and outstanding;

      (c) Any reference to the consent, request or satisfaction of the Holder or
like term, and any action to be taken by the Holder, including any amendment to
this Note, any waiver of any provision of this Note, other than an election to
convert this Note under Section 9(a), (b) or (c), shall mean and be a reference
to, and shall require the written consent or approval, of holders of the Notes
holding more than fifty percent (50%) of the principal amount of the Notes then
outstanding, and any such consent, waiver, amendment, election or other action
shall be binding on all of the holders of the Notes; provided that no such
consent, waiver or amendment shall be effective (i) to reduce or eliminate the
obligation to repay the outstanding principal on the Notes and accrued interest
at the rates provided in Section 3; or (ii) to alter or amend the consent
mechanism provided for under Section 10 or this Section 11, without, in the case
of clause (i), the approval of the holders of each Note affected thereby and, in
the case of clause (ii), all holders of the Notes then outstanding; provided
further that each holder of Notes may exercise its rights and remedies as a
creditor of NaviSite and each Principal Subsidiary if an Event of Default shall
have occurred and be continuing.

                                       9
<PAGE>
      (d) Upon any assignment of this Note by the Holder to any Affiliate of the
Holder or to each stockholder of the Holder as set forth above, in order to
efficiently administer (i) the delivering of any notices to holders of the Notes
by the Company, and (ii) the obtaining of any consent, waiver, amendment or
election from, or the taking of any other action by, the holders of the Notes,
the holders of the Notes shall designate a note holder representative (the
"Representative") and shall promptly deliver notice to the Company of such
designation, including the name and contact information for such Representative.
Initially, the Representative shall be Spectrum Equity Investors III, L.P.,
attn: Michael J. Kennealy.

      Upon such assignment of this Note and the designation of the
Representative by the holders of the Notes, the Representative shall be
authorized (i) to take all action necessary in connection with obtaining any
consent, waiver, amendment or election from the holders of the Notes in
accordance with the requirements hereof, (ii) to give and receive all notices
required to be given under the Notes, and (iii) to take any and all additional
action as is contemplated to be taken by or on behalf of the holders of the
Notes by the terms of this Note.

      Upon designation of the Representative by the holders of the Notes, (i)
the Company shall be able to rely conclusively on the instructions and
representations of the Representative as to the taking of any action by, or the
obtaining of any waiver, amendment or consent from the holders of the Notes in
accordance with the requirements of hereof, (ii) any notice delivered by the
Company to the Representative shall be deemed delivered to all holders of the
Notes, and (iii) no holders of the Notes shall have any cause of action against
the Company for any action taken by the Company in reliance upon the
instructions or representations of the Representative.

      In the event that the Representative dies, becomes unable to perform his
responsibilities hereunder or resigns from such position, holders of the Notes
holding more than 50% of the principal amount of the Notes then outstanding
shall promptly select another representative to fill such vacancy and such
substituted representative shall be deemed to be the Representative for all
purposes hereunder.

      The Representative shall not be liable to any holder of the Notes for any
action taken by him pursuant to this Section 11 unless he has acted in bad faith
or engaged in willful or intentional misconduct, and each holder of a Note, by
receipt of such Note, agrees to jointly and severally indemnify the
Representative from any losses arising out of or relating to his service as such
hereunder, it being expressly understood that the Representative shall be
entitled to reimbursement from the holders of the Notes for his costs and
expenses (including, without limitation, reasonable attorneys' fees) incurred by
Representative in his capacity as such, which third-party costs and expenses
may, at the request of the Representative, be paid by the Company to the
Representative at the time of any payment of principal or interest hereunder,
and which shall constitute a reduction in the unpaid balance of this Note.

      (e) At any time at which there are two or more holders of this Note,
NaviSite shall keep a register in which it shall provide for the registration of
the Notes and the registration of transfers of the Notes, and a copy of such
register (and updates thereto) shall be provided to the Representative. The
holder of any Note may, prior to maturity or prepayment thereof, surrender such
Note at the principal office of NaviSite for transfer or exchange. Any holder
desiring to transfer or exchange any Note shall first notify the Company in
writing at least five (5) days in

                                       10
<PAGE>
advance of such transfer or exchange and, if reasonably requested by the
Company, shall deliver an opinion of counsel (which opinion and counsel shall be
reasonably satisfactory to the Company, it being agreed that Goodwin Procter LLP
shall be satisfactory) to the effect that such assignment is exempt from the
registration requirements of the Securities Act of 1933. Within a reasonable
time after such notice to NaviSite from a holder of its intention to make such
exchange and without expense (other than transfer taxes, if any) to such holder,
NaviSite shall issue in exchange therefor another Note in the same aggregate
principal amount or if requested by the holder in denominations of at least
$500,000 and multiples thereof, except in the case of a Note for the balance of
the aggregate amount of the Note so transferred, as of the date of such
issuance, as the unpaid principal amount of the Note so surrendered and having
the same maturity and rate of interest, containing the same provisions and
subject to the same terms and conditions as the Note so surrendered (provided
that no minimum shall apply to a liquidating distribution of Notes to
stockholders of the Holder or any subsequent holder and any Notes so distributed
may be subsequently transferred by such stockholder and its successors in the
original denomination thereof without further restriction). Each new Note shall
be made payable to such Person or Persons, or assigns, as the holder of such
surrendered Note may designate, and such transfer or exchange shall be made in
such a manner that no gain or loss of principal or interest shall result
therefrom. NaviSite shall have no obligation hereunder or under any Note to any
Person other than the registered holder of each such Note at any time that
NaviSite maintains a register of Notes as provided in this paragraph.

      (f) If this Note is mutilated, destroyed, lost or stolen, upon receipt of
evidence satisfactory to NaviSite of such loss, theft, destruction or mutilation
of this Note and, if requested in the case of any such loss, theft or
destruction, upon delivery of an indemnity agreement holding NaviSite harmless,
which agreement is reasonably satisfactory to NaviSite, or, in the case of any
such mutilation, upon surrender and cancellation of this Note, NaviSite and its
Principal Subsidiaries shall issue a new Note of like tenor and amount and dated
the date to which interest has been paid, in lieu of this Note; provided,
however, if any Holder that is an initial holder hereof and this Note is lost,
stolen or destroyed, the affidavit of an authorized partner or officer of such
holder setting forth the circumstances with respect to such loss, theft or
destruction shall be accepted as satisfactory evidence thereof, and no
indemnification bond or other security shall be required as a condition to the
execution and delivery by NaviSite of a new Note in replacement of this Note
other than the holder's written agreement to indemnify NaviSite and hold
NaviSite and its Affiliates harmless from any claims resulting from such loss,
theft, destruction or mutilation.

12.   Method of Payments; Multiple Payees.

      All payments to be made under this Note shall be made in United States
dollars by wire transfer or by check of immediately available funds to the
account or accounts specified by the Holder in writing and delivered to NaviSite
in the manner specified in Section 14 below. If this Note is assigned to one or
more parties pursuant to Section 11 hereof, any payments made by NaviSite
hereunder shall be made to such holders pro rata based on the total principal
outstanding under such notes.

shall the amount paid or agreed to be paid to the Holder for the use or the
forbearance of the obligations of NaviSite and its Subsidiaries hereunder exceed
the maximum permissible under applicable law. As used herein, the term

<PAGE>
"applicable law" shall mean the law in effect as of the date hereof; provided,
however, that in the event there is a change in the law which results in a
higher permissible rate of interest, then this provision shall be governed by
such new law as of its effective date. In this regard, it is expressly agreed
that it is the intent of NaviSite and each of its Subsidiaries and the Holder in
the execution, delivery and acceptance of this Note to contract in strict
compliance with the laws of The State of Delaware from time to time in effect.
If, under or from any circumstances whatsoever, fulfillment of any provision
hereof at the time of performance of such provision shall be due, shall involve
transcending the limit of such validity prescribed by applicable law, then the
obligation to be fulfilled shall automatically be reduced to the limits of such
validity, and if under or from any circumstances whatsoever the Holder should
ever receive as interest an amount which would exceed the highest lawful rate,
such amount which would be excessive interest shall be applied to the reduction
of the principal balance of the obligations of the Company hereunder, as
determined by the Holder, and not to the payment of interest.

                                    RECITALS

            such Services when ordered. Commitments against this Agreement shall
            be in the form of a Statement of Work (collectively, hereinafter
            "Statement(s) of Work") which shall be deemed to be part of this
            Agreement and which shall contain, at a minimum, the following
            information: (a) the term of performance of the Services authorized
            by the Statement of Work or the date by which performance shall be
            completed; (b) the fee schedule, plus a description of any other
            costs to be paid by Customer relating to the Services, including all
            travel, per diem, , and other related charges; (c) the services,
            actions, and Deliverables to be provided by Vendor to Customer; and
            (d) the Statement of Work shall reference and state that the terms
            and conditions of this Agreement shall govern the Statement of Work.
            Customer shall have no obligation to pay Vendor for any activities
            performed without a Statement of Work.

      2.2   If Schedule A to this Agreement states that Vendor shall provide
            Services in phases, Vendor agrees to perform each phase of Services
            in the order specified by Schedule A to this Agreement, and at the
            conclusion of each phase to submit a progress report to Customer
            that certifies that Vendor has completed all the tasks that were a
            part of that phase. Each progress report shall be signed by an
            authorized manager of Vendor who shall certify that the
            representations contained therein are complete and accurate. The
            progress report shall also set forth any changes recommended by
            Vendor with respect to any remaining phases of Services.

3.    CUSTOMER ACCEPTANCE UPON SATISFACTION OF TESTS.

      3.0   Except as otherwise set forth in a Statement of Work, the terms of
            Sections 3,1 through 3.3 below shall apply only to Deliverables
            provided on a fixed-price basis.

      3.1   Pursuant to the terms set forth in Schedule A to this Agreement,
            Vendor shall deliver the Deliverables to Customer and shall notify
            Customer of the readiness of the Deliverables for testing by
            Customer (the date of such notification hereinafter being referred
            to as the "Delivery Date").

      3.2   Customer shall have [**] business days after the Delivery Date to
            complete testing of the Deliverables. If this test establishes that
            the Deliverables do not materially conform to the requirements set
            forth in Schedule A, Customer shall forthwith notify Vendor and
            Vendor shall, within a reasonable time, modify or otherwise improve
            the Deliverables in an effort to make the Deliverables conform to
            the applicable requirements.

            If no written notification of material non-conformance is received
            by Vendor within [**] business days following the Delivery Date of
            the Deliverables, the Deliverables shall be deemed accepted by
            Customer.

      3.3   If Customer notifies Vendor in writing of any material
            non-conformance in the Deliverables, and Vendor is unable to remedy
            any non-conformance despite two (2) attempts to do so (or such other
            number of attempts that the parties shall mutually agree to),
            Customer's sole and exclusive remedy shall be to reject the
            defective Deliverables and to recover from Vendor the full amount
            paid by Customer to Vendor for the defective Deliverables and any
            Deliverables materially adversely affected by the failure of the
            defective Deliverables.

                                                                    Page 2 of 13

4.    DUTIES AND OBLIGATIONS OF CUSTOMER.

      4.1   Customer shall pay Vendor for its performance of Services in
            accordance with the terms of this Agreement (including Schedule B)
            and the price and schedule of progress payments set forth in
            Schedule A to this Agreement. For Services rendered on a
            time-and-materials basis, the rates and terms in the attached
            Schedule B shall apply and invoices will be provided to Customer on
            a monthly basis for Services performed in the prior month. Except as
            otherwise set forth in a Statement of Work, invoices shall not be
            submitted until the Deliverables provided in accordance with the
            Statement of Work have been accepted by Customer in accordance with
            Section 3 above. Each invoice shall refer to the applicable
            Statement of Work and where applicable the hours expended, the
            applicable rates or other performance measurement authorized by the
            Statement of Work, the time period covered by the invoice, and
            details of any costs and expenses, which are reimbursable or
            payable. Except as otherwise set forth in Schedule B or a Statement
            of Work, Vendor shall provide original receipts for costs or
            expenses reimbursable under the terms of the Statement of Work. The
            rates specified in Schedule B shall be valid for a period of one
            year from the Effective Date. In addition to the above, all fees for
            Services performed pursuant to this Agreement will include an
            additional [**] percent ([**]%) charge for technology and
            administrative fees. (The [**] percent charge shall only apply to
            Services' fees, and shall not apply to any expenses, which may be
            reimbursable and/or payable.) Invoices shall be payable [**] days
            from receipt by Netegrity and shall be payable by wire transfer to
            Vendor's account in Fremont, California.

      4.2   Customer will pay the cost of travel to the primary place of work as
            provided in Schedule B.

      4.3   Customer shall pay or reimburse Vendor for all taxes paid or
            incurred based on work performed or products delivered pursuant to
            this Agreement, except for any tax based on Vendor's net income or
            personal property, Vendor employee withholding taxes, or taxes which
            Vendor advised Customer in writing were not applicable.

      4.4   Customer shall promptly provide Vendor with a complete library of
            any necessary source code and Documentation if the Services that
            Vendor is required to perform under this Agreement include
            modification of existing Customer software.

      4.5   Customer shall cooperate fully with Vendor's performance of
            Services.

      4.6   Customer shall provide Vendor's employees who will be working
            on-site at Customer's premises with suitable office facilities,
            including computing resources, clerical support and reprographic
            facilities, required for carrying out Services under this Agreement.

      4.7   Customer shall provide link connectivity between Customer's site and
            Vendor's communication center in the United States to support and
            help facilitate work performed abroad for Customer by Vendor.
            Customer shall take all steps necessary for the security of its
            network. Vendor shall take all applicable security measures at its
            end of the network.

5.0   OWNERSHIP

      5.1   All computer software and documentation, databases, reports and
            other copyrightable materials, product designs, inventions,
            discoveries, developments and improvements written, invented, made
            or conceived by Vendor in the course of or arising out of the
            Services (hereafter "Work Product") shall become and remain the sole
            and exclusive property of Customer. Vendor shall promptly notify
            Customer in writing of all such Work Product. All copyrightable
            materials, including software and computer programs, produced by
            Vendor in rendering Services hereunder shall be deemed "works made
            for hire" under applicable copyright law. Vendor hereby transfers
            and assigns to Customer all right, title and interest in and to all
            Work Product including all copyrights and patent rights, whether or
            not copyright or patent applications are filed thereon.

      5.2   Upon request and at the expense of Customer, Vendor will, from time
            to time during and after the term of this Agreement, (a) make or
            assist in applications upon such Work Product through attorneys and
            representatives designated by Customer for copyright and/or patent
            in the United States and in all other countries and shall assign

                                                                    Page 3 of 13
<PAGE>
            such applications to Customer, or execute all instruments reasonably
            requested by Customer to perfect or enforce its rights in and to the
            Work Product.

      5.3   In consideration of the opportunity to provide Services hereunder,
            Vendor for itself and its employees and successors hereby waives and
            agrees not to assert or act upon any moral rights or author's rights
            with respect to the Work Product, including without limitation any
            rights of paternity, integrity, and disclosure.

      5.4   Vendor shall obtain any necessary agreements from its employees to
            affect Customer's ownership rights as provided in this Section 5.

      5.5   Notwithstanding the above, the Customer acknowledges that all or
            part of the Services may contain general know-how and prior
            intellectual property of Vendor, which is used or useable in
            connection with the providing of products and services by Vendor to
            other persons, firms and entities. Accordingly, Customer agrees that
            Vendor may use all such know-how and prior intellectual property in
            connection with the providing of products and services to others.
            All rights in such general know-how and prior intellectual property,
            including but not limited to utility routines, generalized
            interfaces, algorithms, ideas, techniques, concepts, proprietary
            processes, tools, methodologies and improvements thereon shall
            continue to vest in Vendor. Should such general know-how and prior
            intellectual property form a part of the Deliverables, Vendor grants
            to Customer a non-exclusive and perpetual license to use such
            know-how and prior intellectual property to enable Customer's and
            Customer's personnel's use and Customer's sublicense of such
            Deliverables in connection with Customer's products and services.

      5.6   Except as otherwise agreed by the parties in writing, provided that
            Vendor makes no use of Customer's intellectual property or
            Confidential Information, nothing in this Agreement shall be
            construed so as to preclude Vendor from developing, using or
            marketing software that is competitive with that prepared for
            Customer hereunder, irrespective of whether such software is similar
            in functionality or design or is otherwise related to the
            Deliverables developed by Vendor for Customer pursuant to this
            Agreement.

6.    REPRESENTATIONS AND WARRANTIES

      6.1   Vendor warrants that any Services rendered by Vendor shall be
            performed with the care and skill ordinarily used by other members
            of Vendor's profession practicing under similar conditions at the
            same time and in the same locality. Vendor shall only assign
            personnel to perform services for Customer who are competent and
            qualified to do so. If, however, in Customer's reasonable opinion
            any of Vendor's personnel fail to carry out the Services
            competently, Customer may notify Vendor and Vendor shall promptly
            rectify the situation at no additional cost to Customer.

      6.2   Except as otherwise set forth in a Statement of Work, Vendor further
            warrants that, to the extent that any Services rendered hereunder
            involve the provision of or modification to computer code, the
            results thereof (the "Results") shall be Year 2000 compliant. "Year
            2000 Compliant" means that means that the Results will be capable of
            correctly processing, providing, and/or receiving date data,
            including the correct processing of leap years, within and between
            the twentieth and twenty-first centuries and handling the century
            date rollover. Vendor shall have no responsibility or liability for
            any failure of the Results to be Year 2000 Compliant if such failure
            is caused by or related to: (i) Customer or third party hardware,
            firmware, software or data not provided and/or modified by Vendor
            that interfaces with, is manipulated by, or otherwise operates in
            conjunction with the computer code, including but not limited to
            inconsistencies between the date handling characteristics of the
            computer code and such Customer or third party hardware, firmware,
            software, components or data, or (ii) modification of the computer
            code provided by Vendor by Customer or a third party, if such
            modification results in the computer code not being Year 2000
            Compliant.

      6.3   Customer represents and warrants that it possesses the legal right
            to have the intellectual property with respect to which Vendor is to
            perform Services under this Agreement used, maintained and modified
            by Vendor.

      6.4   THE EXPRESS WARRANTIES SET FORTH IN THIS AGREEMENT ARE THE ONLY
            WARRANTIES MADE, AND THERE ARE NO OTHER WARRANTIES, EXPRESS OR
            IMPLIED, AND SPECIFICALLY THERE ARE NO IMPLIED WARRANTIES OF
            MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

                                                                    Page 4 of 13

7.    INDEMNIFICATION.

      7.1   Except as provided in Section 7.3 below, Vendor shall, at its own
            expense, defend or, at its option, settle any claim, suit, or action
            brought against Customer by third parties for infringement or
            misappropriation of a third party's copyright, patent, trade secret,
            or other intellectual property right by any Deliverables provided by
            Vendor to Customer under this Agreement, and shall pay any damages
            or settlement assessed against Customer under such a claim. Vendor
            shall have sole control and authority over the defense or settlement
            of such a claim, suit or action, including the right, at its sole
            discretion, to (i) procure for Customer the right to use the
            infringing Deliverables, (ii) replace the infringing Deliverables
            with non-infringing, functionally equivalent Deliverables, (iii)
            suitably modify the infringing Deliverables, or (iv) accept return
            of the infringing Deliverables and refund any fees paid by Customer
            to Vendor with respect to the infringing Deliverables. Customer
            shall be obligated to give Vendor prompt written notice of, and the
            parties shall cooperate in, the defense of any claim, suit or
            action, including appeals and negotiations. This indemnity shall not
            extend to any claim of infringement or misappropriation resulting
            from Customer's specifications, modification of the Deliverables
            unless made by Vendor, and use or incorporation of the Deliverables
            in a manner for which the Deliverables were not designed or with
            items not provided by Vendor, if such claim of infringement would
            not have arisen but for such conformance to specification,
            modification, or incorporation. Except as specified above, Vendor
            shall not be liable for any costs or expenses incurred without its
            prior written authorization.

      7.2   SECTION 7.1 ABOVE STATES THE ENTIRE INDEMNITY OBLIGATIONS OF VENDOR,
            AND THE EXCLUSIVE REMEDY OF CUSTOMER, WITH RESPECT TO ANY ACTUAL OR
            ALLEGED INFRINGEMENT OF ANY PATENT, COPYRIGHT, TRADE SECRET, OR
            OTHER INTELLECTUAL PROPERTY RIGHT BY SOFTWARE PROVIDED BY VENDOR TO
            CUSTOMER UNDER THIS AGREEMENT.

      7.3   Except as provided in Section 7.1 above, Customer shall, at its own
            expense, defend any claim, suit, or action brought against Vendor by
            third parties for infringement or misappropriation of a third
            party's copyright, patent, trade secret or other intellectual
            property rights by any intellectual property provided by Customer to
            Vendor under this Agreement, and shall pay any damages or settlement
            assessed against Vendor under such a claim. Vendor shall be
            obligated to give Customer prompt written notice of, and the parties
            shall cooperate in, the defense of any claim, suit or action,
            including appeals and negotiations. This indemnity shall not extend
            to any claim of infringement or misappropriation resulting from the
            Vendor's modification of such intellectual property, if such claim
            would not have arisen but for such modification. Except as specified
            above, Customer shall not be liable for any costs or expenses
            incurred without its prior written authorization.

      7.4   SECTION 7.3 ABOVE STATES THE ENTIRE INDEMNITY OBLIGATIONS OF
            CUSTOMER, AND THE EXCLUSIVE REMEDY OF VENDOR, WITH RESPECT TO ANY
            ACTUAL OR ALLEGED INFRINGEMENT OF ANY PATENT, COPYRIGHT, TRADE
            SECRET, OR OTHER INTELLECTUAL PROPERTY RIGHT BY ANY INTELLECTUAL
            PROPERTY PROVIDED BY CUSTOMER TO VENDOR UNDER THIS AGREEMENT.

      7.5   Customer and Vendor shall each indemnify, defend, and hold harmless
            the other from any claim or damages due to the injury or death of
            any individual, or the loss or damage to real or tangible personal
            property, resulting from the willful acts or omissions or gross
            negligence of the indemnifying party, its agents or employees.

8.    LIMITATION OF LIABILITY.

      EACH PARTY'S LIABILITY, WHETHER IN CONTRACT, TORT, OR OTHERWISE, FOR ANY
      CLAIM ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT SHALL NOT EXCEED
      THE TOTAL AMOUNT PAID TO VENDOR BY CUSTOMER UNDER THE APPLICABLE STATEMENT
      OF WORK FROM WHICH THE CLAIM AROSE OR IS RELATED. IN NO EVENT SHALL EITHER
      PARTY BE LIABLE FOR COSTS OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES
      BY ANYONE, NOR SHALL EITHER PARTY BE LIABLE FOR ANY INDIRECT, SPECIAL,
      INCIDENTAL, CONSEQUENTIAL, OR PUNITIVE

                                                                    Page 5 of 13
<PAGE>
      DAMAGES, HOWEVER CAUSED, INCLUDING, WITHOUT LIMITATION, ANY DAMAGES
      RESULTING FROM LOSS OF USE, LOSS OF DATA, LOSS OF PROFITS OR LOSS OF
      BUSINESS ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT, OR OF ANY
      OTHER OBLIGATIONS RELATING TO THIS AGREEMENT, WHETHER OR NOT THE PARTY HAS
      BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THIS PARAGRAPH SHALL NOT
      APPLY TO DAMAGES RESULTING FROM WRONGFUL DISCLOSURE OF CONFIDENTIAL
      INFORMATION, INFRINGEMENT OF THE OTHER PARTY'S INTELLECTUAL PROPERTY
      RIGHTS, OR EITHER PARTY'S INDEMNIFICATION OBLIGATIONS IN SECTION 7 ABOVE.

9.    TERM OF AGREEMENT.

            The term of this Agreement shall commence on the Effective Date and
      shall continue unless terminated in accordance with the provisions of this
      Agreement. The provisions of Sections 5, 6, 7, 8, 12.2, and 12.4 of this
      Agreement shall survive any termination, cancellation or expiration of
      this Agreement.

10.   TERMINATION.

      10.1  Either party has the right to terminate this Agreement (a) if the
            other breaches or is in default of any obligation hereunder which
            default is incapable of cure or which, being capable of cure, has
            not been cured within ten (10) calendar days after receipt of notice
            of such default (or such additional cure period as the nondefaulting
            party may authorize) or (b) immediately upon the adoption of any
            applicable law, rule or regulation, or revision thereof, or upon any
            change in the interpretation or administration thereof, that
            materially affects Customer's rights or interests in Work Product
            and/or the Deliverables, provided that after termination under this
            subsection (b) Customer shall pay Vendor for Services provided to
            the date of termination and Vendor's costs incurred and otherwise
            payable hereunder.

      10.2  Customer may terminate this Agreement and/or any Statement of Work
            issued hereunder at any time without cause by submitting to Vendor
            thirty (30) calendar days' prior written notice to terminate. Upon
            receipt of such notice, Vendor shall perform only those efforts
            necessary to close out any ongoing project within thirty days, as
            determined by consultation with Customer, or otherwise as Customer
            may direct. Such efforts may include without limitation the
            following: employee relocation, summary of work to date, and
            identification of work yet unfinished. Vendor shall promptly notify
            Customer of costs incurred to the effective date of termination and
            Customer shall pay all such unpaid allowed and supported fees and
            costs, related to such termination, but excluding charges for the
            period following the effective date of termination for activities
            not reasonably necessary to close out the project. Vendor may
            terminate this Agreement at any time without cause by submitting to
            Customer sixty (60) calendar days' prior written notice to
            terminate; provided that such termination shall not affect the
            completion of any Statement of Work which is in progress, and such
            Statement of Work shall continue to be governed by the terms and
            conditions of this Agreement. Notwithstanding the foregoing, Vendor
            may terminate an open-ended Statement of Work without a specified
            end date for convenience upon sixty (60) days' prior written notice
            to Customer.

      10.3  Either party may terminate this Agreement by written notice to the
            other and may regard the other party as in default of this
            Agreement, if the other party becomes insolvent, makes a general
            assignment for the benefit of creditors, files a voluntary petition
            of bankruptcy, suffers or permits the appointment of a receiver for
            its business or assets, or becomes subject to any proceedings under

            failure which arises from causes beyond a party's reasonable control

            performance has been so affected shall immediately give notice to

            unable to perform, Customer shall have the right to keep such
            papers, materials and other properties until such time as Customer
            has found a comparable replacement for Vendor.

            binding unless made in writing and signed by both Customer and
            Vendor. The failure of either Customer or Vendor at any time or
            times to require performance of any provision hereof shall in no
            manner affect the right at a later time to enforce such provision.
            No remedy referred to in this Agreement is intended to be exclusive,
            but each shall be cumulative and in addition to any other remedy
            referred to herein or otherwise available at law, in equity or
            otherwise.

      12.2  Confidential and Proprietary Information. The provisions of the
            Mutual Non-Disclosure Agreement between Vendor and Customer dated
            November 17, 2000 are hereby incorporated by reference.

      12.3  Independent Contractors. It is expressly understood that Vendor and
            Customer are contractors independent of one another, and that
            neither has the authority to bind the other to any third person or
            otherwise to act in any way as the representative of the other,
            unless otherwise expressly agreed to in a writing signed by both
            parties hereto. Vendor shall have the right to assign or subcontract
            any of its obligations under this Agreement to others. If any of its
            obligations under this Agreement are assigned or subcontracted to
            others, Vendor shall take steps to ensure that its

                                                                    Page 7 of 13
<PAGE>
            assignee or subcontractor observe and enforce the confidentiality
            requirements and the intellectual property ownership assignment
            provisions of this Agreement.

      12.4  Non-Solicit/No-Hire. Except as otherwise expressly agreed in
            writing, Vendor and Customer each agree not to directly or
            indirectly or through third parties knowingly solicit or hire for
            employment any of the other party's personnel who are involved in
            the provision of Services hereunder while any such person is
            involved in the provision of Services, and for a period of [**]
            following such person's provision of Services hereunder. For the
            purposes hereof, "knowingly" shall mean that the representatives of
            a party responsible for hiring or soliciting of employees, or
            approving the same, has knowledge, or reasonably could have been
            expected to have knowledge, of this provision.

      12.5  Customer Name. Six (6) months following the Effective Date and
            thereafter during the term of this Agreement only, Vendor may
            include Customer's name in a general listing of Vendor customers.
            Inclusion of Customer's name in the general customer list shall not
            imply endorsement of Vendor by Customer.

      12.6  Arbitration. Except for matters relating to either party's
            intellectual property rights, any unresolved dispute or controversy
            arising under or in connection with this Agreement shall be settled
            exclusively by arbitration, conducted before a panel of three
            arbitrators in Boston, Massachusetts, in accordance with the rules
            of the American Arbitration Association then in effect. The
            arbitrators shall not have the authority to add to, detract from, or
            modify any provision hereof nor to award punitive damages to any
            injured party. A decision by a majority of the arbitration panel
            shall be final and binding. Judgment may be entered on the
            arbitrators' award in any court having jurisdiction.

      12.7  Authority; Compliance with Laws. Vendor represents that it has all
            licenses, permits, and authorization necessary and has obtained all
            approvals from any government office, board of directors or
            shareholders necessary to carry out the Services and related
            activities and to comply with the terms of this Agreement. Vendor
            acknowledges that certain information, including but not limited to
            Work Product, may be restricted by law of the United States
            Government and other governments from export and import to certain
            countries and certain organizations and individuals, and agrees to
            comply with such laws. Vendor agrees that no information or Work
            Product or portion thereof will be exported or re-exported by
            Vendor, except to Customer in the United States or as Customer
            otherwise directs. In performing any activities hereunder, Vendor
            agrees to comply with the U.S. Foreign Corrupt Practices Act and all
            applicable laws and regulations of the United States and any other
            government with jurisdiction over Vendor. Vendor warrants that any
            personnel of Vendor offered to Customer hereunder for work in the
            United States is authorized to work in the United States, according
            to the Immigration Reform and Control Act (IRCA). Vendor also
            certifies that it has on file a validly completed Federal Form I-9
            (Employment Eligibility Verification) for each such offered
            personnel and will provide a certified copy of said form to Customer
            upon Customer's request.

      12.8  Governing Law. This Agreement shall be governed by, and construed
            and enforced in accordance with, the substantive laws of the
            Commonwealth of Massachusetts, without regard to its principles of
            conflicts of laws. The state and federal courts located in
            Massachusetts shall have nonexclusive jurisdiction of all matters
            and disputes arising under this Agreement or in connection with the
            Services performed and/or Work Product provided hereunder. The
            United Nations Convention on the Sale of Goods shall not apply to
            this Agreement.

      12.9  Entire Agreement. This Agreement, including the Schedules attached
            hereto, sets forth the entire agreement and understanding of the
            parties with respect to the subject matter hereof, and supersedes

            understandings, representations, conditions and all other
            communications relating thereto.

                                                                    Page 8 of 13
