         The following unaudited pro forma condensed combined financial
statements reflect the acquisition by the Registrant of IMC in exchange for
shares of the Registrant's Common Stock and options to purchase shares of the
Registrant's Common Stock.  The acquisition was accounted for using the
purchase method of accounting.  The pro forma condensed combined balance sheet
assumes the merger took place on January 24, 1997 and combines the January 24,
1997 balance sheet of the Registrant with the January 31, 1997 balance sheet of
IMC. The pro forma condensed combined statement of operations for the fiscal
year ended April 30, 1996 assumes the acquisition took place as of the
beginning of the fiscal year and combines the Registrant's historical results
for the fiscal year ended April 30, 1996 (for which period IMC was not in
operation) with  pro forma adjustments.  The pro forma condensed combined
statement of operations for the nine months ended January 24, 1997 assumes the
acquisition took place as of the beginning of the most recently completed
fiscal year and combines the Registrant's historical results for the nine
months ended January 24, 1997 with the historical results of IMC for the period
from inception (May 6, 1996) to January 31, 1997.  The pro forma condensed
combined statements of operations exclude the effect of any nonrecurring
charges directly attributable to the acquisition.

         The pro forma information is presented for illustrative purposes only
and is not necessarily indicative of the operating results or financial
position that would have occurred had the acquisition of IMC by the Registrant
been consummated at the beginning of the periods presented, nor is it
necessarily indicative of future operating results or financial position. These
pro forma financial statements are based on and should be read in conjunction
with the historical consolidated financial statements and the related notes
thereto of the Registrant and IMC.

         NOTES TO PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

  1.     On March 17, 1997 the Registrant acquired IMC in exchange for
approximately 187,023 shares of the Registrant's Common Stock and options to
purchase shares of the Registrant's Common Stock.  In connection with the
acquisition certain former employees of IMC who entered into employment
agreements with the Registrant were granted options to purchase shares of the
Registrant's Common Stock at a discount to the market price of the Registrant's
Common Stock immediately preceding the acquisition.  IMC was founded in 1996 to
develop and commercialize Internet/Intranet proxy caching software.  The
acquisition was accounted for as a purchase.

        In connection with the acquisition, intangible assets of $8.4 million
were acquired by the Registrant of which $7.4  million was allocated to
in-process research and development and will be charged to operations in the
fiscal quarter ending April 30, 1997 as the technology had not achieved
technological feasibility and had no alternative future use.  The remaining $1.0
million of intangible assets will be amortized over an estimated useful life of
five years.  Also in connection with the acquisition, a compensation expense of
$3.2 million, relating to the granting of discounted stock options, will be
charged to operations in the fiscal quarter ending April 30, 1997.

        The pro forma condensed combined statements of operations for the fiscal
year ended April 30, 1996 and for the nine months ended January 24, 1997 exclude
the impact of the nonrecurring charge associated with expensing in-process
research and development and the one-time compensation charge, net of deferred
taxes, related to the granting of options to certain former IMC employees to
purchase shares of the Registrant's Common Stock at a discount to the market
price of the Registrant's Common Stock immediately preceding the acquisition.

        The unaudited pro forma condensed combined financial statements give
effect to the merger of the Registrant and IMC on a purchase accounting basis.
The pro forma condensed combined balance sheet assumes the merger took place on
January 24, 1997 and combines the January 24, 1997 balance sheet of the
Registrant with the January 31, 1997 balance sheet of IMC. The pro forma
condensed combined statement of operations for the fiscal year ended April 30,
1996 assumes the merger took place as of the beginning of the fiscal year and
combines the Registrant's historical results for the fiscal year ended April
30, 1996 (for which period IMC was not in operation) with pro forma
adjustments. The pro forma condensed combined statement of operations for the
nine months ended January 24, 1997 assumes the merger took place as of the
beginning of the most recently completed fiscal year and combines the
Registrant's historical results for the nine months ended January 24, 1997 with
the historical results of IMC for the period from inception (May 6, 1996) to
January 31, 1997.   

2.       The pro forma condensed combined financial statements included herein
have been prepared by the Registrant, without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission.  Certain information and
footnote disclosures normally prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules and
regulations.  However, the Registrant believes that the disclosures are
adequate to make the information not misleading.  These pro forma condensed
combined financial statements should be read in conjunction with the financial
statements and the notes thereto included in the Registrant's annual report on
Form 10-K for the fiscal year ended April 30, 1996 and the financial statements
of IMC included in this filing.

3.       Net income per share for each period is calculated by dividing net
income by the weighted average number of common and common equivalent shares
outstanding during the period plus approximately 172,375 shares of the
Registrant's Common Stock which was exchanged for all issued and outstanding
shares of IMC Common Stock. Common equivalent shares consist of stock options
(using the treasury stock method).
