         On October 28, 2002, we offered to eligible option holders the
opportunity to exchange certain outstanding options to purchase shares of our
common stock that have an exercise price greater than $10.00 per share for new
options to purchase shares of our common stock. This Supplement amends and
supplements the offering materials that we sent to all eligible option holders
on October 28, 2002. Except as amended or supplemented below, the original
terms and conditions of the offering materials remain in effect. Please read
this Supplement together with those offering materials.

         This Supplement is being delivered to you via electronic mail. Hard
copies of this Supplement may be obtained at no cost by contacting: Stephanie
Shaw, Caminus Corporation, 825 Third Avenue, New York, New York 10022; Tel:
(212) 515-3600; Fax: (212) 893-8747.

         1.       Each of the final sentence of the third paragraph on the
cover page of the Offer to Exchange, the final sentence in the question "How
Many New Options Will I Receive in Exchange for My Tendered Options" in the
Summary Term Sheet Section of the Offer to Exchange, and the final sentence of
the third paragraph in Section 1 of the Offer to Exchange is replaced in its
entirety with the following:

         A separate new option will be granted in exchange for each old option
that is validly tendered and accepted for exchange. Accordingly, two or more
eligible old options will not be consolidated into a single new option grant.

         2.       The final paragraph in Section 5 of the Offer to Exchange is
replaced in its entirety with the following:

         Promptly after the expiration of the Offer, we will send each
tendering option holder a letter indicating the number of shares subject to the
options that we have accepted for exchange and that have been cancelled, the
corresponding number of shares that will be subject to the new options, and the
expected grant date of the new options.

         3.       The first subparagraph in Section 6 of the Offer to Exchange
is replaced in its entirety with the following:

         -     any action or proceeding by any government agency, authority or
               tribunal or any other person, domestic or foreign, is threatened
               or pending before any court, authority, agency or tribunal that
               directly or indirectly challenges the making of the Offer, the
               acquisition of some or all of the surrendered options, the
               issuance of new options, or otherwise relates to the Offer or
               that, in our reasonable judgment, could materially and adversely
               affect our business, condition (financial or other), income,
               operations or prospects or materially impair the benefits we
               believe we will receive from the Offer, including (i)

                                      -1-

               the creation of strong performance incentives for our
               employees, and (ii) the retention of our employees;

         4.       The second subparagraph in Section 6 of the Offer to Exchange
is replaced in its entirety with the following:

         -     any action is threatened, pending or taken, or any approval is
               withheld, by any court or any authority, agency or tribunal
               that, in our reasonable judgment, would or might directly or
               indirectly:

               -  make it illegal for us to accept some or all of the
                  surrendered options or to issue some or all of the new
                  options or otherwise restrict or prohibit consummation of the
                  Offer or otherwise relate to the Offer;

               -  delay or restrict our ability, or render us unable, to accept
                  the surrendered options for exchange or to issue new options
                  for some or all of the surrendered options;

               -  materially impair the benefits we believe we will receive
                  from the Offer, including (i) the creation of strong
                  performance incentives for our employees, and (ii) the
                  retention of our employees; or

               -  materially and adversely affect our business, condition
                  (financial or other), income, operations or prospects;

         5.       The third paragraph in Section 8 of the Offer to Exchange is
replaced in its entirety with the following:

         Eligible option holders who participate in the Offer will receive a
new option on the new grant date in exchange for each old option that was
validly tendered and accepted for exchange. The number of shares covered by
each new option will be equal to the number of shares covered by the old option
that was exchanged for such new option, subject to adjustments for any stock
splits, stock dividends and other events affecting our capital structure that
occur before the grant date of the new option. A separate new option will be
granted in exchange for each old option that is validly tendered and accepted
for exchange. Accordingly, two or more eligible old options will not be
consolidated into a single new option grant.

         Each new option will be granted under the 1999 Plan, the 2001 Plan or
a nonplan stock option agreement, as to be determined by Caminus in its sole
discretion. In selecting the plan under which a new option will be granted, we
will consider various factors, including the following: (i) only non-officer
employees may be granted options under the 2001 Plan, and accordingly we will
grant options to non-officer employees under the 2001 Plan to the greatest
extent possible; and (ii) incentive stock options may be granted only under the
1999 Plan.

         6.       The following new sentence is inserted at the end of the
fourth paragraph in Section 8 of the Offer to Exchange:

         Our Board of Directors will determine the fair market value of the new
options in the event that our common stock is not listed on Nasdaq (or any
securities exchange or over-the-counter market) on the date of grant of the new
options.

                                      -2-

         7.       The sixth paragraph in Section 8 of the Offer to Exchange is
replaced in its entirety with the following:

         Notwithstanding whether any old option tendered for exchange is a
non-qualified stock option or an incentive stock option, we will grant the new
option issued in exchange for such old option as either a non-qualified stock
option or an incentive stock option, in our sole discretion. In determining
whether to grant a new option as a non-qualified stock option or an incentive
stock option, we will consider various factors, including the fact that
incentive stock options may only be granted under the 1999 Plan and accordingly
may only be granted if there is availability under the 1999 Plan. Except as
provided in the preceding sentences of this paragraph and except with respect
to the exercise price, the vesting schedule and as otherwise specified in the
Offer, we expect that to the extent legally permissible the terms and
conditions of the new options will be substantially the same as the terms and
conditions of the options tendered for exchange.

         8.       The eighth paragraph in Section 8 of the Offer to Exchange is
replaced in its entirety with the following:

         The following description summarizes the material terms and conditions
of the 1999 Plan and the 2001 Plan, under which new options may be granted. If
new options are granted under a nonplan stock option agreement, we expect that
the terms of such nonplan stock option agreement will not be materially
different from those of the 1999 Plan or the 2001 Plan. Option holders who
exchange old options granted under the 1998 Plan for new options granted under
the 1999 Plan or the 2001 Plan should understand that there are certain
differences between the 1998 Plan, on the one hand, and the 1999 Plan and the
2001 Plan, on the other hand. For instance, incentive stock options may be
granted under the 1998 Plan and the 1999 Plan, but incentive stock options may
not be granted under the 2001 Plan. In addition, under the 1998 Plan, the
exercise price of options must be paid in cash, while under the 1999 Plan and
the 2001 Plan several forms of payment are permitted. There also are other
differences between the rights of option holders under the 1998 Plan and the
rights of option holders under the 1999 Plan and the 2001 Plan, none of which
are material.

         The following description concerning the 1999 Plan and the 2001 Plan
is merely a summary and does not purport to be complete. The description is
subject to, and is qualified in its entirety by reference to, all provisions of
such Option Plans. See Section 17 of this Offer to Exchange for a discussion of
how to obtain copies of these Option Plans.

         9.       The following new sentence is inserted at the end of the
first paragraph in Section 18 of the Offer to Exchange:

         The safe harbor afforded by the Private Securities Litigation Reform
Act of 1995 to certain forward-looking statements does not extend to statements
made by Caminus in connection with the Offer.

         10.      The second sentence on page 5 of the Letter of Transmittal is
replaced in its entirety with the following:

         I agree to all of the terms and conditions of the Offer.

                                      -3-

         11.      The final sentence in the first paragraph following the
salutation in the Notice of Withdrawal of Tender is deleted in its entirety.
