Item 7.   Financial Statements and Exhibits

     (b)  Pro forma financial information:
          -------------------------------

   On August 18, 1999, CMGI, Inc. ("the Company" or "CMGI") acquired an 81.495%
equity stake in the former AltaVista division of Digital Equipment Corporation
("the AltaVista Business") from Compaq Computer Corporation ("Compaq) and its
wholly-owned subsidiary Digital Equipment Corporation ("Digital"), for
consideration preliminarily valued at approximately $2.420 billion, including
approximately $4 million of direct costs of the acquisition. The AltaVista
Business includes the assets and liabilities constituting the AltaVista Internet
search service ("AltaVista Search"), which was a division of Digital, and also
includes former Compaq/Digital wholly-owned subsidiaries Zip2 Corporation and
Shopping.com. In consideration for the acquisition, the Company issued
18,994,975 shares of its common stock valued at approximately $1.816 billion,
18,090.45 shares of its Series D Preferred Stock (which were converted into
1,809,045 shares of CMGI common stock on October 28, 1999) valued at
approximately $173 million and promissory notes for an aggregate principal
amount of $220 million. Additionally, AltaVista Business and CMGI stock options
issued in the transaction, preliminarily valued at approximately $203 million
and $4 million, respectively, have been included in the purchase consideration.

   The unaudited Pro Forma Condensed Combined Statement of Operations (the "Pro
Forma Statement of Operations") for the year ended July 31, 1999 gives effect to
the acquisition of the AltaVista Business as if it had occurred on August 1,
1998. The Pro Forma Statement of Operations is based on historical results of
operations of the Company for the year ended July 31, 1999 and the historical
results of the components of the AltaVista Business as follows: the carve-out
historical results of AltaVista Search and the historical results of Zip2
Corporation for the twelve months ended June 30, 1999 and the historical results
of Shopping.com for the twelve months ended July 31, 1999. The unaudited Pro
Forma Condensed Combined Balance Sheet as of July 31, 1999 (the "Pro Forma
Balance Sheet") gives effect to the acquisition of the AltaVista Business as if
the acquisition had occurred on that date. The Pro Forma Balance Sheet is based
on the historical balance sheet of the Company as of July 31, 1999 and the
historical balance sheet of the AltaVista Business as of June 30, 1999. The Pro
Forma Statements of Operations and Pro Forma Balance Sheet and the accompanying
notes (collectively the "Pro Forma Financial Information") should be read in
conjunction with and are qualified by the historical financial statements of the
Company and notes thereto.

   The Pro Forma Financial Information is intended for informational purposes
only and is not necessarily indicative of the future financial position or
future results of operations of the consolidated company after the acquisition
of the AltaVista Business, or of the financial position or results of operations
of the consolidated company that would have actually occurred had the
acquisition of the AltaVista Business been effected as of the dates described
above.

 Notes to the Unaudited Pro Forma Condensed Combined Financial Information


(1)  Pro Forma Adjustments and Assumptions

     (A)  The Company acquired an 81.495% equity stake in the AltaVista Business
          for consideration preliminarily valued at approximately $2.420 billion
          on August 18, 1999, including costs of acquisition (see description of
          the components of the consideration above). The following represents
          the allocation of the purchase price over 81.495% of the historical
          net book values of the acquired assets and liabilities of the
          AltaVista Business as of the date of the Pro Forma Balance Sheet, and
          is for illustrative purposes only. The actual purchase price
          allocation will be based on fair values of the acquired assets and
          liabilities as of the actual acquisition date (August 18, 1999).
          Assuming the transaction occurred on July 31, 1999, the allocation
          would have been as follows (in thousands):

                    Working capital deficit                         $  (18,808)
                    Property, plant and equipment                       34,301
                    Other non-current assets                            18,618
                    Other non-current liabilities                       (3,106)
                    Goodwill and other intangible assets             2,388,995
                                                                    ----------
                    Purchase price                                  $2,420,000
                                                                    ==========

          The pro forma adjustment reconciles the historical balance sheet of
          the AltaVista Business to the allocated purchase price above and
          includes the accrual of approximately $4.0 million of estimated
          acquisition costs to be paid by CMGI. The cash and cash equivalents of
          the AltaVista Business as of August 18, 1999 were retained by Compaq
          at the date of acquisition and, accordingly, the pro forma adjustment
          and the allocation of the purchase price as of July 31, 1999 include
          the effect of this event.

     (B)  The pro forma adjustment includes $796.3 million in amortization of
          goodwill and other intangible assets (per the allocation in "(A)"
          above) that would have been recorded during the period covered by the
          Pro Forma Statement of Operations. The adjustment amount has been
          reduced by $132.8 million, which represents 81.495% of the
          amortization of goodwill and other intangible assets recorded in the
          historical financial statements of the AltaVista Business. The
          historical financial statements of the AltaVista Business represented
          in the Pro Forma Statement of Operations include amortization of
          goodwill and other intangible assets totaling $163.0 million. These
          amounts relate to Compaq's acquisition of Digital in June 1998 and
          Compaq/Digital's acquisitions of Shopping.com and Zip2 Corporation in
          January 1999 and April 1999, respectively. The pro forma adjustment
          also includes an increase in expense of $24.9 million, which
          represents 18.505% of the incremental amount of goodwill and other
          intangible assets amortization that would have been recorded in the
          historical financial statements of the AltaVista Business if
          Compaq/Digital's acquisitions of Shopping.com and Zip2 Corporation had
          occurred on August 1, 1998.

          The pro forma adjustment is based on the assumption that the entire
          amount identified as goodwill and other intangible assets in CMGI's
          acquisition of the AltaVista Business will be amortized on a straight-
          line basis over a three-year period. The Company has not yet completed
          the valuation of the actual intangible assets acquired at August 18,
          1999. When completed, certain amounts identified as intangible assets
          may be amortized over periods other than the three-year period
          represented in the Pro Forma Statement of Operations. Additionally, a
          portion of the purchase price may be identified as in-process research
          and development. This amount, if any, will be charged to operating
          results in the Company's fiscal 2000 when the acquisition accounting
          and valuation are determined. The Pro Forma Statement of Operations
          does not give effect to any potential in-process research and
          development charge related to the acquisition of the AltaVista
          Business.

     (C)  The pro forma adjustment is a reduction in expense of $8.9 million,
          which relates to stock-based compensation charges recorded in the
          historical financial statements of the AltaVista Business. The value
          of the stock options to which these charges related have been included
          in the calculation of the purchase consideration, or would have been
          included in the pre-acquisition financial statements of the AltaVista
          Business. Accordingly, on a pro forma basis, these expenses have been
          eliminated.

 Notes to the Unaudited Pro Forma Condensed Combined Financial Information
                                  (Continued)


     (D)  The pro forma adjustment reflects the interest expense that would have
          been recorded by CMGI related to the $220 million of aggregate
          principal amounts of notes payable issued in the acquisition of the
          AltaVista Business. The notes bear interest at an annual rate of
          10.5%.

     (E)  The pro forma adjustment reflects the 18.505% minority interest in the
          results of operations of the AltaVista Business assuming that CMGI's
          acquisition of 81.495% of the AltaVista Business occurred on August 1,
          1998.

     (F)  The pro forma adjustment reflects the income tax benefit that would
          have been recorded by the Company in its consolidated statement of
          operations related to the AltaVista Business' net loss and the income
          tax effect, if any, of the other pre-tax pro forma adjustments. The
          pro forma adjustment assumes that the Company would be able to
          recognize a federal tax benefit for the amortization of goodwill and
          other intangible assets related to the acquisition of the AltaVista
          Business. The pro forma adjustment also assumes that the Company would
          record a valuation allowance for all state tax benefits associated
          with the AltaVista Business. Actual effective tax rates may differ
          from pro forma rates reflected herein.

     (G)  Since the Pro Forma Statement of Operations results in a loss from
          continuing operations, the pro forma basic and diluted loss from
          continuing operations per common share are computed by dividing the
          loss from continuing operations available to common stockholders by
          the weighted average number of common shares outstanding. The
          calculation of the weighted average number of common shares
          outstanding assumes that the 18,994,975 shares of the Company's common
          stock issued in the acquisition of the AltaVista Business were
          outstanding for the entire period. The calculation of the weighted
          average number of common shares outstanding also assumes that the
          18,090.45 shares of the Company's Series D preferred stock were
          converted into 1,809,045 shares of the Company's common stock on
          October 11, 1998 (the 71/st/ day after the assumed acquisition date of
          August 1, 1998) and that such common shares were outstanding for the
          entire period thereafter. The Series D preferred shares were converted
          into common stock on October 28, 1999 (the 71/st/ day after the actual
          acquisition date of August 18, 1999).
