                                    AMENDMENT
                                       TO
                   AGREEMENT OF SEVERANCE, WAIVER AND RELEASE

          This Amendment to Agreement of Severance, Waiver and Release (this
"Amendment") is made as of December 1, 1999, between UBICS, Inc., a Delaware
corporation ("UBICS") and Manohar B. Hira ("Hira").

                                    PREAMBLE:

          UBICS and Hira are parties to an Agreement of Severance, Waiver and
Release dated March 18, 1999 (the "Severance Agreement"), which sets forth the
terms of Hira's retirement from employment with UBICS effective on January 1,
2000. The Severance Agreement contemplated that UBICS would acquire R Systems,
Inc. and the President of R Systems, Inc. would become the President and Chief
Executive Officer of UBICS. UBICS did not acquire R Systems. Inc. and has not
yet hired a new President and Chief Executive Officer. The parties therefore
wish to amend the Severance Agreement to provide for the continued employment of
Hira by UBICS through March 31, 2000.

          Therefore, UBICS and Hira, intending to be legally bound, agree as
follows:

          1.        The first sentence of Section 1 of the Severance Agreement
shall be amended to read as follows:

                    Hira shall retire and his employment with UBICS will
                    terminate on March 31, 2000 (the "Termination Date").

          2.        Section 2 of the Severance Agreement shall be amended in its
entirety to read as follows:

                    2. Resignation as President and Director. Hira hereby
                    resigns from the office of President of UBICS effective on
                    the earlier of (a) the date on which UBICS hires a new
                    President and Chief Executive Officer (the "Hiring Date") or
                    (b) the Termination Date. The parties acknowledge that Hira
                    was not nominated for reelection to the Board of Directors
                    of UBICS at the 1999 Annual Meeting of Stockholders of
                    UBICS, but that on December 1, 1999, the Board of Directors
                    of UBICS elected Hira to fill the vacancy on the Board
                    created by the resignation of Craig A. Wolfanger. Hira
                    hereby resigns from the Board of Directors of UBICS
                    effective on the Termination
<PAGE>   2
                    Date. During the period from the Hiring Date until the
                    Termination Date, Hira shall perform such duties as shall be
                    necessary or appropriate to make a transition of his
                    responsibilities to the new President and Chief Executive
                    Officer, and shall perform such other duties and
                    responsibilities as the Board of Directors, Chairman or
                    President of UBICS may from time to time designate.

          3.        The first sentence of Section 3 of the Severance Agreement
shall be amended to read as follows:

                    Provided Hira continues to perform his duties as employee of
                    UBICS through January 1, 2000, UBICS shall pay Hira a
                    severance payment of $450,000.00 in cash as follows:
                    $150,000.00 on the Termination Date, and $100,000.00 on each
                    of the first three anniversaries of the Termination Date, in
                    each case minus applicable deductions, as a severance.

          4.        Section 8 of the Severance Agreement shall be amended in its
entirety to read as follows:

                    8. Stock Options. In consideration of Hira agreeing to
                    extend his retirement date until March 31, 2000, UBICS
                    hereby grants to Hira options (the "New Options") to
                    purchase 35,000 shares of common stock at an exercise price
                    of $2.50 per share, all in accordance with the terms of a
                    separate stock option agreement between UBICS and Hira dated
                    as of December 1, 1999. Upon the Termination Date, all
                    options to purchase common stock of UBICS held by Hira,
                    including the New Options, shall immediately vest and be
                    exercisable by Hira or his estate until the expiration date
                    of such options, which is on the tenth anniversary of the
                    date of grant. In the event that [,on or prior to the
                    Termination Date,] the Board of Directors determines to
                    reduce the exercise price of its outstanding options, to
                    issue new options to replace such outstanding options, or to
                    issue additional options to holders of such outstanding
                    options, the Company will also reprice or replace Hira's
                    options (other than the New Options) or issue additional
                    options to Hira (other than with respect to the New
                    Options), as the case may be, on the same basis,

                                      -2-

                    provided that any such new or additional options shall be
                    fully vested and exercisable upon issuance.

          5.        Except as set forth above, the Severance Agreement shall
remain unchanged and in full force and effect.

          IN WITNESS WHEREOF, the parties hereto have executed this Amendment as
of the date first written above.

                   AGREEMENT OF SEVERANCE, WAIVER AND RELEASE

          This Amendment No. 2 to Agreement of Severance, Waiver and Release
(this "Amendment") is made as of March 31, 2000, between UBICS, Inc., a Delaware
corporation ("UBICS"), and Manohar B. Hira ("Hira").

                                    PREAMBLE:

          UBICS and Hira are parties to an Agreement of Severance, Waiver and
Release dated March 18, 1999, as amended on December 1, 1999 (the "Severance
Agreement"), which sets forth the terms of Hira's retirement from employment

wish to amend further the Severance Agreement to provide for the continued
employment of Hira by UBICS on a month-to-month basis following the Termination
Date.

          Therefore, UBICS and Hira, intending to be legally bound, agree as
follows:

          1.        Notwithstanding the provisions of Section 1 of the
Severance Agreement, Hira shall continue to be employed by UBICS on a month-to-
month basis from and after the Termination Date, and during such time Hira shall
receive compensation and benefits pursuant to, and Hira and UBICS shall be
bound by the other terms of, the Employment Agreement, except as otherwise
provided in this Amendment or in the Severance Agreement, as amended hereby.
Either UBICS or Hira may elect to terminate Hira's employment effective as of
the last day of any calendar month by giving to the other party written notice
of such intent to terminate on or before the 15th day of the month in which such
termination is to be effective. The effective date of such termination shall be
the "Final Termination Date" for purposes of the Severance Agreement and this
Amendment. On the Final Termination Date, except as otherwise provided in the
Severance Agreement, as amended hereby, the Employment Agreement shall terminate
and be of no further force and effect and the parties shall be released from all
of their obligations under the Employment Agreement.

          2.        Section 2 of the Severance Agreement shall be amended in its

                    President and Chief Executive Officer (the "Hiring Date") or
                    (b) the Final Termination Date. The parties acknowledge that
                    Hira was not nominated for reelection to the Board of
                    Directors of UBICS at the 1999 Annual Meeting of
                    Stockholders of UBICS, but that on December 1, 1999, the
                    Board of Directors of UBICS elected Hira to fill the vacancy
                    on the Board created by the resignation of Craig A.
                    Wolfanger.

                    the Hiring Date until the Final Termination Date, Hira shall

                    make a transition of his responsibilities to the new

                    such other duties and responsibilities as the Board of
                    Directors, Chairman or President of UBICS may from time to
                    time designate.

                    Period"), Hira shall be entitled to continued participation
                    in the medical insurance plans maintained by UBICS for its
                    employees.

          5.        Section 6 of the Severance Agreement shall be amended in its

                    Date.
