     This Agreement and Plan of Merger (this "Merger Agreement") dated as of

"Parent"), and DDi Merger Co., a Delaware corporation that is a wholly owned

     The Parent's Board of Directors has determined that it is advisable and in
the best interests of the Parent and its stockholders to reincorporate the
Parent as a Delaware corporation.  The purpose of this Merger Agreement is to
effect such reincorporation through the merger of the Parent with and into the
Subsidiary.

in accordance with this Merger Agreement, the Delaware General Corporation Law,
and the California Corporations Code (the "Merger").  From and after the
Effective Time (as defined in Section 2 below), the separate existence of the
Parent shall terminate and the Subsidiary shall continue in existence as the
surviving corporation (the "Surviving Corporation").  The Surviving Corporation
shall be governed by the laws of the State of Delaware.

     2.   EFFECTIVE TIME OF MERGER.  Following (i) the requisite approval of the
Merger and this Merger Agreement by the shareholders of the Parent and (ii) the
execution and filing of a Certificate of Ownership and Merger pursuant to
Section 253 of the Delaware General Corporation Law and Section 1110 of the
California Corporations Code, the Merger shall become effective immediately
prior to the initial public offering of the Common Stock, $.01 par value, of the
Surviving Corporation (the "Effective Time").

     3.   CERTIFICATE OF INCORPORATION AND BY-LAWS OF SURVIVING CORPORATION.
From and after the Effective Time, the Certificate of Incorporation (including
without limitation the authorized capital stock set forth therein) and the by-
laws of the Subsidiary shall be the Certificate of Incorporation and by-laws,
respectively, of the Surviving Corporation.  Article I of the Certificate of
Incorporation of the Surviving Corporation shall, by effect of the Merger, be
amended to read as follows:

     "The name of this corporation is "DDi Corp." (hereinafter referred to as
     the "Corporation")."

     4.   DIRECTORS AND OFFICERS.  From and after the Effective Time, the
respective directors and officers of the Subsidiary shall continue in office as
the directors and officers of the Surviving Corporation, subject to the

          Restated and Amended Articles of Incorporation, based on the

          of the Parent and the Subsidiary; and

          and outstanding immediately before the Effective Time (after giving
          effect to clause (c) above) shall be converted into and become a
          number of fully paid and non-assessable shares of  the Common Stock of
          the Surviving Corporation equal to the Conversion Ratio;

          (iii)  pursuant to Section 155 of the Delaware General Corporation
          Law, each fractional share of the Surviving Corporation's capital
          stock that is issued and outstanding shall be redeemable by the
          Surviving Corporation for cash in an amount to be determined by
          multiplying such fraction of a share by the initial public offering
          price per share;

          (ii) all treasury shares of the Class A-1, Class A-2, Class A-3, Class
          A-4, Class A-5, Class A-6, Class A-7 and Class L Common Stock of the

<PAGE>

          would have acquired in the Merger had the options and warrants been
          exercised immediately prior to the reclassification described in
          clause (b) above with appropriate adjustments to the exercise price to
          reflect the effect of such reclassification and the Merger.

     (e) Cancellation of Shares of the Subsidiary's Capital Stock.  As of the
Effective Time, automatically and without further actions, each share of the
Subsidiary's capital stock that was issued and outstanding or held in treasury
immediately before the Effective Time shall be canceled and returned to the
status of an authorized but unissued share of capital stock.

     (f) Exchange of Certificates.  From and after the Effective Time, the
certificates formerly representing shares of the Parent's capital stock that
have been converted into shares of the Surviving Corporation's capital stock in
accordance with this Merger Agreement shall thereafter represent the shares of
the Surviving Corporation's capital stock into which the shares of the Parent's
capital stock formerly represented thereby have been so converted, regardless of
whether such certificates are surrendered to the Surviving Corporation,
provided, however, that the Surviving Corporation shall not be obligated to
issue new certificates evidencing such shares of its capital stock unless and
until the old certificates are either delivered to the Surviving Corporation, or
in any particular case the registered holder thereof notifies the Surviving
Corporation that such certificates have been lost, stolen, or destroyed and
executes an agreement satisfactory to the Surviving Corporation to indemnify the
Surviving Corporation and its officers, directors, employees, agents, and
representatives, including without limitation its transfer agent(s), from and
against any loss or damage incurred in connection therewith.
