Exhibit 10.1

                FIRST AMENDMENT TO REGISTRATION RIGHTS AGREEMENT

          FIRST AMENDMENT (this "Amendment") dated June __, 2006 to the
Registration Rights Agreement (the "Agreement") dated June 10, 2004, by and
between NaviSite, Inc., a Delaware corporation (the "Company"), and Waythere,
Inc., a Delaware corporation formerly known as Surebridge, Inc. ("Waythere").
All capitalized terms used herein but not otherwise defined shall have the
meanings ascribed to such terms in the Agreement. The Agreement shall continue
in full force and effect in accordance with its terms, except to the extent
amended hereby.

          NOW, THEREFORE, the parties hereto, in consideration of the mutual
covenants and agreements hereinafter set forth, and other good and valuable
consideration, the receipt and sufficiency of which hereby are acknowledged,
agree as follows:

          (1) Section 1(e) (Incidental Registration) of the Agreement is hereby
     deleted in its entirety and of no further force or effect.

          (2) Section 1(f) (Limitations of Subsequent Registration Rights) of
     the Agreement is hereby deleted in its entirety and of no further force or
     effect.

          (3) Waythere hereby agrees and covenants that it shall not file, or
     cause or permit to be filed, a Form 144 with the Securities and Exchange
     Commission with respect to the sale or proposed sale of any shares of the
     Company's common stock, $0.01 par value per share (the "Common Stock"),
     during the 25 day trading period beginning on June 2, 2006.

          (4) Waythere hereby agrees that it shall not sell or otherwise
     transfer or dispose (collectively, the "Standstill") of any shares of
     Common Stock owned or controlled by it for up to 25 trading days between
     June 2, 2006 and December 31, 2006. Waythere and the Company hereby agree
     that Friday, June 2, 2006 was the first of such 25 trading days, and that
     Waythere shall continue to honor the Standstill after the date hereof until
     the earlier of (i) receipt of written notice from the Company that the
     Standstill has been suspended; or (ii) the end of the twenty-fifth trading
     day after June 2, 2006. The Company shall use its best efforts to provide
     at least one day's written notice to Waythere in the event an additional
     Standstill is imposed by the Company under this Section 4 after the date
     hereof. For the avoidance of doubt, in the event the Company suspends the
     Standstill prior to the expiration of the twenty-fifth trading day, the
     Company shall be permitted at any time prior to December 31, 2006 to impose
     an additional Standstill for up to the number of days equal to 25 less the
     number of trading days that were subject to and included within a
     Standstill previously imposed by the Company pursuant to this Amendment.
     The Company may impose stop-transfer instructions with respect to the
     shares of Common Stock owned by it during any Standstill.

          (5) The parties hereto hereby agree and acknowledge that the first day
     of the 60 day period referenced in Section 1(b)(iv) occurred on June 2,
     2006 and that the suspension of the effectiveness of any Registration
     Statement and the use of the



     Prospectus shall continue pursuant to the terms thereof until Waythere
     receives written notice thereof from the Company or until such period
     expires by its terms. In addition, the following words "and/or the sales of
     the Registrable Securities" shall be deleted from Section 1(b)(iv) of the
     Agreement and shall be of no further force or effect.

          (6) The Company, or its counsel, shall provide, within five days after
     receipt of a written request from Waythere, an appropriate legal opinion to
     the Company's transfer agent with respect to Rule 144(K) of the Securities
     Act of 1933, as amended (the "Securities Act"), provided that all
     appropriate documentation that is reasonably requested by the Company or
     its counsel is received on such date. In addition, the Company, or its
     counsel, shall provide, within two business days after receipt of a written
     request from Waythere, an appropriate legal opinion to the Company's
     transfer agent with respect to sales by Waythere pursuant to Rule 144 of
     the Securities Act, provided that all appropriate documentation and
     representation letters that are reasonably requested by the Company or its
     counsel is received on such date. Notwithstanding the foregoing, the
     Company and its counsel shall have no obligations under this Section 6 in
     the event (i) the Company or its counsel reasonably determines that
     Waythere is not compliant with the requirements of Rule 144(K) or Rule 144;
     or (ii) Waythere is then subject to a Standstill.

          (7) The definition of "Initial Registrable Securities" is hereby
     amended and restated in its entirety to mean (a) the "Parent Shares" under
     the Purchase Agreement and (b) any shares of capital stock issued or
     issuable, from time to time, upon any reclassification, share combination,
     share subdivision, stock split, share dividend, merger, consolidation or
     similar transaction or event or otherwise as a distribution on, in exchange
     for, of or with respect to, the shares of Common Stock described in (a), in
     each case held at the relevant time by an Investor. As to any particular
     securities, such securities will cease to be Initial Registrable Securities
     (i) when they have been transferred in a public offering registered under
     the Securities Act, (ii) when they have been transferred in a sale made
     through a broker, dealer or market-maker pursuant to Rule 144 under the
     Securities Act, (iii) when the Investors (including for this purpose the
     stockholders of Waythere) are or would be able to sell all of such
     securities under Rule 144 under the Securities Act during any 90-day period
     without restriction (including without limitation, as to volume by the
     holder thereof), (iv) on January 1, 2007, or (v) when they have been
     transferred other than as permitted by the Purchase Agreement, the Notes
     and this Agreement.

          (8) Section 1(a)(ii) is hereby amended to read in its entirety "The
     Company shall use its reasonable best efforts to cause any such Initial
     Registration Statement described in Section 1(a)(i) to remain effective (or
     if required by applicable law, to cause another Registration Statement with
     respect to the Initial Registrable Securities to become effective) until
     the earlier of (i) such time as all of such securities have been sold by
     Waythere and (ii) December 31, 2006."
