provided for illustrative purposes only and are not necessarily indicative of
future results or the results that actually would have occurred if the

1.  ACQUISITIONS

ALTRA ACQUISITION

On November 20, 2001, Caminus completed its acquisition of Altra, a provider of
software solutions to the energy industry, by purchasing from Altra Energy
Technologies, Inc. ("Altra Energy"), all of the capital stock of Altra pursuant
to a Stock Purchase Agreement, dated as of October 12, 2001, by and between
Caminus and Altra Energy. The purchase price of $60,794 consisted of $24,947 in
cash, the issuance of 1,975 shares of common stock ("Shares") with a fair value
of $33,891 and approximately $1,956 of other direct acquisition costs including
liabilities for severance. The purchase price is subject to  adjustment,
depending on the final determined value of the tangible net worth, as defined,
of Altra, as more fully described in the Stock Purchase Agreement. The cash
portion of the purchase price was paid for in part from the proceeds of a
$15,000 Term Credit Agreement, dated as of November 20, 2001, between Caminus
and Blue Ridge Investments, LLC, and in part from Caminus' cash and cash
equivalents. The Shares issued to Altra Energy were authorized, but previously
unissued, shares of Caminus' Common Stock. Altra Energy is entitled to certain
registration rights with respect to the Shares, as more fully described in the
Registration Rights Agreement, dated as of November 20, 2001, by and between
Caminus and Altra Energy.

A summary of the allocation of the acquisition purchase price is as follows:


                                                                     
Fair value of net tangible liabilities assumed...................      $(11,207)
Acquired in-process research and development.....................         1,300
Acquired technology..............................................        17,659
Other identifiable intangible assets.............................        11,100
Goodwill.........................................................        41,942
                                                                       --------
                                                                       $ 60,794
                                                                       ========




The acquisition was accounted for under the purchase method of accounting. The
fair value assigned to intangible assets acquired was based on a preliminary
appraisal. Upon completion of the appraisal to estimate the fair value of the
assets acquired, the allocation of the purchase price may change. Acquired
in-process research and development represents the fair value of the project
under development at the date of acquisition. Acquired technology represents
the fair value of applications and technologies existing at the date of
acquisition. Other intangible assets represent the fair value of customer
relationships. Goodwill is the only intangible asset not subject to
amortization, although it will be deductible for tax purposes over fifteen
years.

NUCLEUS ACQUISITION

         On August 30, 2000, Caminus acquired substantially all of the assets
and assumed certain liabilities of Nucleus, a provider of software solutions to
the energy industry. The purchase price of $17,606 consisted of $13,584 in
cash, the issuance of 261 shares of common stock with a fair value of $3,757
and approximately $265 of other direct acquisition costs. A summary of the
allocation of the acquisition purchase price is as follows:


                                                                    
Fair value of net tangible liabilities assumed ...........             $   (391)
Acquired technology ......................................                2,960
Other identifiable intangible assets .....................                3,007
Goodwill .................................................               12,030
                                                                       --------
                                                                       $ 17,606
                                                                       ========


The acquisition was accounted for under the purchase method of accounting. The
fair value assigned to intangible assets acquired was based on an appraisal.
Acquired technology represents the fair value of applications and technologies
existing at the date of acquisition. Other intangible assets represent the fair
value of other acquired intangible assets including primarily customer lists, a
covenant not to compete and work force in place.

2. PRO FORMA ADJUSTMENTS

          (h) To record the fair value of the 1,975 shares issued in
              connection with the acquisition, amounting to $33,891.
          (i) To reflect the effect on equity of an in-process research and

              accumulated deficit of Altra.
          (j) To reflect amortization of acquired technology resulting from the
              acquisition.
          (k) To eliminate the amortization of Altra's historical intangible

          (l) To eliminate Altra's historical net interest expense on
              intercompany debt not acquired and reflect interest expense on
              the long-term debt incurred in connection with the
              acquisition of Altra and reduction of interest income related to
              the cash portion of the acquisition costs.


3. UNAUDITED PRO FORMA NET LOSS PER SHARE DATA

Shares used to calculate unaudited pro forma net loss per share data for the
year ended December 31, 2000 were computed by adding the weighted average shares
issued for the Nucleus acquisition for the period from January 1, 2000 to August
30, 2000 of 174 and the 1,975 shares issued for the Altra acquisition to the
weighted average common shares outstanding for Caminus of 14,925. Shares used to
calculate unaudited pro forma net loss per share data for the nine months ended
September 30, 2001 were computed by adding the 1,975 shares issued for the Altra
acquisition to the weighted average common shares outstanding for Caminus of
15,808.
