ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

(a) On November 20, 2001, Caminus Corporation, a Delaware corporation (the
"COMPANY"), completed its acquisition (the "ACQUISITION") of Altra Software
Services, Inc., a Delaware corporation ("ALTRA SOFTWARE"), by purchasing from
Altra Energy Technologies, Inc., a Delaware corporation ("ALTRA ENERGY"), all of
the capital stock of Altra Software pursuant to a Stock Purchase Agreement,
dated as of October 12, 2001, by and between the Company and Altra Energy (the
"STOCK PURCHASE AGREEMENT").

         The purchase price for the Acquisition consisted of 1,975,000 shares
(the "SHARES") of the Company's Common Stock, $0.01 par value per share, and
$24,778,147 in cash. Based on Caminus' closing share price of $17.30 on November
20, 2001, the total purchase price for the Acquisition is approximately $59
million. The purchase price is subject to adjustment, depending on the final
determined value of the tangible net worth, as defined, of Altra Software, 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 $15,000,000 Term
Credit Agreement, dated as of November 20, 2001, between the Company and Blue
Ridge Investments, LLC (the "TERM CREDIT AGREEMENT"), and in part from proceeds
from the Company's initial public offering. The Shares issued to Altra Energy
were authorized, but previously unissued, shares of the Company's 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 the Company and Altra Energy (the
"REGISTRATION RIGHTS AGREEMENT").

         The purchase price for the Acquisition was determined based upon
arm's-length negotiations between the parties. Prior to the execution of the
Stock Purchase Agreement, to the knowledge of the Company, neither the Company
nor any of its affiliates, nor any director or officer of the Company or any
associate of any such director or officer, had any material relationship with
Altra Energy.

         The Company, Altra Energy and JP Morgan Chase Bank entered into an
Escrow Agreement, dated as of November 20, 2001 (the "ESCROW AGREEMENT"),
pursuant to which (i) 348,387 Shares will be held in escrow pending the
distribution thereof to the Company and/or Altra Energy based upon the final
determined value of the tangible net worth, as defined, of Altra Software as of
the closing date, and (ii) 645,162 Shares will be held in escrow pending the
distribution thereof (A) to the Company to reimburse it in connection with
certain indemnification claims, if any, that the Company may make pursuant to
the Stock Purchase Agreement and/or (B) with respect to any Shares still held in
escrow following the expiration of the applicable indemnification periods, to
Altra Energy.

         The foregoing descriptions of the Stock Purchase Agreement, the Term
Credit Agreement, the Registration Rights Agreement and the Escrow Agreement do
not purport to be complete and are qualified in their entirety by reference to
the full texts of such agreements, which are filed hereto as Exhibits 2.1, 99.1,
99.2 and 99.3, respectively, and are incorporated herein by reference.

(b) Certain of the assets of Altra Software acquired by the Company in the
Acquisition constitute equipment and other physical property. Prior to the
Acquisition, Altra Energy,

through Altra Software, created and implemented transaction management software
for the energy industry. The Company currently intends to continue Altra
Software's business substantially in the manner conducted by Altra Energy
immediately prior to the Acquisition.
