          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

  The following unaudited pro forma financial information is included in
this report:

  - Pro Forma Condensed Combined Balance Sheet as of April 30, 2004 (unaudited)

  - Pro Forma Condensed Combined Statement of Operations for the three months
    ended April 30, 2004 (unaudited)

  - Pro Forma Condensed Combined Statement of Operations for the nine months
    ended April 30, 2004 (unaudited)

  - Pro Forma Condensed Combined Statement of Operations for the year ended July
    31, 2003 (unaudited)

  The unaudited pro forma condensed combined balance sheet as of April 30, 2004
combines the unaudited condensed consolidated balance sheet of NaviSite as of
April 30, 2004 with the condensed consolidated balance sheet of Surebridge as of
March 31, 2004.

  The unaudited pro forma condensed combined statement of operations for the
year ended July 31, 2003 combines the unaudited pro forma condensed consolidated
statement of operations of NaviSite for the fiscal year ended July 31, 2003 with
the unaudited condensed consolidated results of operations of Surebridge for the
twelve months ended June 30, 2003. As required under Article 11(c)(3) of
Regulation S-X, Surebridge's December 31, 2002 fiscal year end has been
conformed to be within 93 days of NaviSite's July 31, 2003 fiscal year end by
using Surebridge's results of operations for the twelve months ended June 30,
2003. In addition, the unaudited pro forma condensed combined statements of
operations for the three and nine months ended April 30, 2004 combine the
unaudited condensed consolidated statements of operations of NaviSite for the
three and nine months ended April 30, 2004 with the unaudited condensed
consolidated statements of operations of Surebridge for the three and nine
months ended March 31, 2004.


  The unaudited pro forma condensed combined statement of operations for the
year ended July 31, 2003 also gives pro forma effect to NaviSite's other recent
acquisitions of ClearBlue Technologies, Inc., or CBT, Interliant, Inc., or
Interliant, Conxion Corporation, or Conxion, and ClearBlue Technologies
Management, Inc., or CBTM, as if they had occurred as of August 1, 2002.


  The following is a summary of the additional acquisitions noted above for
which pro forma effect is given in the unaudited pro forma condensed combined
statement of operations for the year ended July 31, 2003 for the portion of the
fiscal year ended July 31, 2003 that each respective company was not owned by
NaviSite:


  - In August 2003, NaviSite acquired all of the outstanding shares of six
    wholly-owned subsidiaries of CBT with data centers in various U.S. locations
    and assumed the revenue and expense of four additional wholly-owned
    subsidiaries of CBT. Pursuant to the acquisition agreement, as amended,
    NaviSite had the right to acquire the four additional subsidiaries for no
    additional consideration at any time on or prior to August 8, 2005. In April
    2004, NaviSite exercised its right to acquire the additional four
    subsidiaries and thereby acquired all of the outstanding shares of the
    additional four wholly-owned subsidiaries of CBT. This transaction was
    accounted for as a combination of entities under common control, similar to
    a pooling-of-interests, whereby the assets and liabilities of the ten
    wholly-owned subsidiaries of CBT (as described above) and NaviSite were
    combined at their historical amounts as of the date CBT had control of both
    entities (September 11, 2002). CBT's results of operations and cash flows
    for the eleven months ended July 31, 2003 are included in NaviSite's
    consolidated statement of operations and consolidated statement of cash
    flows for the year ended July 31, 2003. The subsidiaries of CBT that
    NaviSite acquired are now operated as wholly-owned subsidiaries of NaviSite.


  - In May 2003, NaviSite acquired assets of Interliant related to managed
    messaging, application hosting and application development services.
    Interliant's results of operations and cash flows for

                                        1


    the two-and-one-half months ended July 31, 2003 are included in NaviSite's
    consolidated statement of operations and consolidated statement of cash
    flows for the year ended July 31, 2003. The Interliant business is now
    operated as a wholly-owned subsidiary of NaviSite.

  - In April 2003, NaviSite acquired Conxion, a provider of application hosting,
    content and electronic software distribution and security services.
    Conxion's results of operations and cash flows for the four months ended
    July 31, 2003 are included in NaviSite's consolidated statement of
    operations and consolidated statement of cash flows for the year ended July
    31, 2003. Conxion is operated as a wholly-owned subsidiary of NaviSite.


  - In December 2002, NaviSite acquired all of the issued and outstanding stock
    of CBTM, a wholly-owned subsidiary of CBT, NaviSite's then parent company
    which previously had acquired assets from the bankrupt estate AppliedTheory
    Corporation related to application management and application hosting
    services. As CBT had a controlling interest in both companies at the time of
    the combination, the transaction was accounted for as a combination of
    entities under common control, similar to a pooling-of-interests, whereby
    the assets and liabilities of CBTM and NaviSite were combined at their
    historical amounts as of the date CBT had control of both entities
    (September 11, 2002). CBTM's results of operations and cash flows for the
    eleven months ended July 31, 2003 are included in NaviSite's consolidated
    statement of operations and consolidated statement of cash flows for the
    year ended July 31, 2003. CBTM is operated as a wholly-owned subsidiary of
    NaviSite.


  The unaudited pro forma financial information is not necessarily indicative of
the results of operations or financial position of NaviSite had the transactions
assumed therein occurred, nor are they necessarily indicative of the results of
operations or financial position, which may be expected to occur in the future.
Furthermore, the unaudited pro forma financial information is based on
assumptions that NaviSite believes are reasonable and should be read in
conjunction with NaviSite's Form 10-K for the fiscal year ended July 31, 2003,
Forms 10-Q for the fiscal quarters ended October 31, 2003, January 31, 2004
and April 30, 2004 and Form 8-K dated June 10, 2004 (filed June 14, 2004)
previously filed.

PRO FORMA ADJUSTMENTS AND ASSUMPTIONS

  (A)  PURCHASE PRICE ALLOCATION

  The following represents the preliminary allocation of the estimated purchase
price for NaviSite's acquisition of Surebridge over the historical net book
values of the acquired assets and assumed liabilities of Surebridge as of the
date of the pro forma balance sheet, and is for illustrative purposes only.
Assuming the transaction occurred on April 30, 2004, the estimated purchase
price allocation for the acquisition of Surebridge would have been as follows
(in thousands):

<Table>
                                                            
Working capital, including cash acquired....................   $(3,871)
Property & equipment, net...................................     7,782
Other non-current assets....................................     4,956
Long-term debt..............................................    (1,019)
Non-current liabilities.....................................       (95)
Goodwill....................................................    46,417
                                                               -------
Purchase price..............................................   $54,170

</Table>

  The goodwill adjustment in the pro forma condensed combined balance sheet was
determined as follows (in thousands):

<Table>
                                                            
Elimination of pre-existing Surebridge goodwill.............   $(6,327)
Goodwill resulting from the acquisition (see above).........    46,417
                                                               -------
Goodwill adjustment.........................................   $40,090
                                                               =======
</Table>


  The purchase price allocation for the acquisition of Surebridge is preliminary
and is subject to adjustment upon finalization of the purchase accounting as of
the date of consummation of the acquisition. NaviSite has engaged a third party
to conduct a valuation of the intangible assets acquired. The third-party
valuation firm has not yet completed its valuation, but NaviSite anticipates
that, upon completion of the valuation, a substantial amount of the $46.4
million of preliminary goodwill will be assigned to an amortizable customer list
with an identifiable useful life. Assuming a five-year useful life, every $1.0
million of identifiable intangible assets recorded would result in approximately
$200,000 of annual amortization expense in the pro forma statements of
operations. The final allocation of the excess of the purchase price over the
book value of the net assets acquired could differ materially.


  The primary reasons for the acquisition included the addition of service
offerings, specific contractual relationships with PeopleSoft and Microsoft, and
established contractual revenue base, as well as potential operations savings.
As the primary reasons for the acquisition were not related to the tangible net
assets of Surebridge, the purchase price was significantly in excess of the fair
value of the net assets acquired.


  (B)  COMPONENTS OF THE ESTIMATED PURCHASE CONSIDERATION

  The pro forma financial information reflects NaviSite's acquisition of
substantially all the assets and liabilities of Surebridge for consideration
valued at approximately $54.2 million. The pro forma adjustments reconcile the
historical balance sheet of NaviSite to the allocated purchase price above and

  We must repay the outstanding principal of the promissory notes, with all
accrued interest thereon, no later than June 10, 2006. In addition, if at any
time during the first six months after the date of issuance of the notes we
complete certain equity or debt financings, we are obligated to use a
significant portion of the proceeds to make payments on the notes, depending on
the total net proceeds received by us in the financing. If we receive net
proceeds of less than $20 million in a debt or equity financing, then we would
be obligated to make a payment on the notes equal to 75% of the net proceeds. If
we receive net proceeds of between $20 million and $30 million, then we would be
obligated to make a payment on the notes equal to $15 million. If we receive net
proceeds in excess of $30 million, then we would be obligated to make a payment
on the notes equal to 50% of the net proceeds.


  In addition, if we realize net proceeds in excess of $1.0 million from certain
equity or debt financings or sales of assets at any time after six months from
the date the notes were issued, we are obligated to use a significant portion of
the proceeds to make payments on the notes, depending on the total payments, if
any, made on the notes during the first six months after the notes were issued.
If the amount we paid on the notes during the first six months the notes were
outstanding is less than $10 million, we would be obligated to make a payment on
the notes equal to 75% of the net proceeds. If the amount we paid on the notes
during the first six months the notes were outstanding was greater than $15
million, we would be obligated to make a payment on the notes equal to 50% of
the net proceeds. If the amount we paid on the notes during the first six months
the notes were outstanding is between $10 million and $15 million, we would be
obligated to make a payment on the notes equal to a percentage between 50% and
75% of the net proceeds received, such percentage to be calculated in accordance
with a formula set forth in the notes.
