and IV is incorporated by reference to Part I, Part II and Part IV,

EMPLOYMENT AGREEMENTS
 
     UBICS has entered into substantially identical employment agreements with
Messrs. Mallya, Hira, Nalavadi and Srinivas pursuant to which each of them serve
as an executive officer of the Company. The initial terms of the employment
agreements are three years and the agreements provide for payment of an annual
base salary to Messrs. Mallya, Hira, Nalavadi and Srinivas of $150,000,
$120,000, $100,000 and $75,000, respectively, and an annual bonus as determined
by the Compensation Committee of the Board of Directors. The agreements with
Messrs. Mallya, Hira and Nalavadi automatically extend beginning on the second
anniversary of the agreements, so that the remaining term of each agreement is
always one year unless either party gives notice of their intention to terminate
the agreement at the end of the term. The agreements are terminable by UBICS
immediately for cause. The agreements prohibit the executive officers from
competing with UBICS during their employment with UBICS and for one year
thereafter, and from improperly disclosing or using UBICS's proprietary
information. The employment agreements also include the provisions relating to
severance described below.

                                       7
<PAGE>   10
     The employment agreements with each of Messrs. Mallya, Hira, Nalavadi and
Srinivas provide that if, on or after the date of a "Change in Control" (as
defined herein), UBICS, for any reason, terminates the employee's employment or
the employee resigns "for good reason" (as defined herein), then UBICS shall pay
to the employee within five days following the date of termination or date of
resignation, as applicable: (i) the employee's salary and benefits through the
termination date or resignation date, both as in effect on the date prior to the
date of the Change in Control; and (ii) the amount of any bonus payable to the
employee for the year in which the Change in Control occurred, pro rated to take
into account the number of days that have elapsed in such year prior to the
termination date or resignation date. In addition, during a period following the
termination or resignation date equal to the remaining term of the employee's
employment agreement as of the date immediately prior to such termination or
resignation date, UBICS shall continue to pay to the employee his annual salary,
as in effect on the day prior to the date of the Change in Control, on the dates
when such salary would have been payable had the employee remained employed by
UBICS and shall continue to provide to the employee during such specified
period, at no cost to the employee, the benefits the employee was receiving on
the day prior to the date of the Change in Control or benefits substantially
similar thereto.
 
     For purposes of the employment agreements, a "Change in Control" is deemed
to occur upon any of the following events: (i) any individual, corporation,
partnership, association, trust or other entity (other than Mallya or an
affiliate of Mallya) becomes the beneficial owner (as defined in Rule 13d-3
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")),
directly or indirectly, of securities of UBICS representing 50% or more of the
combined voting power of UBICS' then outstanding voting securities; (ii) the
individuals who as of the date of the agreements are members of the Board of
Directors of UBICS (the "Incumbent Board") cease for any reason to constitute at
least a majority of the Board of Directors of UBICS (provided, however, that if
the election, or nomination for election by UBICS' stockholders, of any new
director was approved by a vote of at least a majority of the Incumbent Board,
such new director will, for purposes of such agreements, be considered as a
member of the Incumbent Board); (iii) an agreement by UBICS to consolidate or
merge with any other entity pursuant to which UBICS will not be the continuing
or surviving corporation or pursuant to which shares of the Common Stock of
UBICS would be converted into cash, securities or other property, other than a
merger of UBICS in which holders of the Common Stock of UBICS immediately prior
to the merger would have the same proportion of ownership of Common Stock of the
surviving corporation immediately after the merger; (iv) an agreement of UBICS
to sell, lease, exchange or otherwise transfer in one transaction or a series of
related transactions substantially all of the assets of UBICS; (v) the adoption
of any plan or proposal for a complete or partial liquidation or dissolution of
UBICS; or (vi) an agreement to sell more than 50% of the outstanding voting
securities of UBICS in one or a series of related transactions other than an
initial public offering of voting securities registered with the Commission.
 
     The term "good reason" means: (i) a material diminution by UBICS of the
employee's title or responsibilities, as that title and those responsibilities
existed on the day prior to the date of a Change in Control; or (ii) a material
diminution by UBICS in the employee's salary, benefits or incentive or other
forms of compensation, all as in effect on the day prior to the date of a Change
in Control.
 
     UBICS and Manohar B. Hira, currently President and a director of UBICS,
have entered into an Agreement of Severance, Waiver and Release (the "Severance
Agreement") pursuant to which Mr. Hira has agreed to resign as President of
UBICS effective on the closing date of the Exchange. The Severance Agreement
also provides that Mr. Hira will not be nominated and will not stand for
reelection to the Board of Directors of UBICS at the Annual Meeting. Mr. Hira
will continue as an employee of UBICS until his retirement on January 1, 2000
and will assist in the integration of the respective businesses of UBICS and R
Systems and perform such other duties as may be designated from time to time by
the Board, the Chairman or the President of UBICS.
 
     The Severance Agreement provides that UBICS will pay Mr. Hira a severance
payment of $450,000, payable in installments of $150,000 on January 1, 2000 (the
"Termination Date") and $100,000 on each of the first through third
anniversaries of the Termination Date. In addition, all stock options held by
Mr. Hira shall vest and be exercisable by Mr. Hira or his estate effective upon
consummation of the Exchange until the expiration date of such options. If UBICS
determines, in connection with the Exchange, to reduce the exercise price of its
outstanding stock options or to issue new options to replace the outstanding
options, Mr. Hira's options will also be repriced or replaced, as the case may
be, on the same basis. UBICS also agreed to amend a mortgage note dated June 24,
1998 from Mr. Hira to UBICS (the "Note") in the principal amount of $250,000 to
eliminate all scheduled installment payments and provide that the principal
amount and all accrued interest shall be due and payable on the fourth
anniversary of the Termination Date. Mr. Hira agreed to release UBICS and its
present and former officers, directors, employees, agents and attorneys from any
and all claims, suits, damages and expenses related to or arising out of Mr.
Hira's employment or termination of employment with UBICS.

INDEMNIFICATION AGREEMENTS
 
     The Company has entered into indemnification agreements with each of its
directors pursuant to which the Company has agreed to indemnify such party to
the full extent permitted by law, subject to certain exceptions, if such party
becomes subject to an action because such party is a director, officer,
employee, agent or fiduciary of the Company. Upon consummation of the Exchange
UBICS will enter into a similar indemnification agreement with Satinder Singh
Rekhi, Gen. Baldev Singh and Deborah Colden upon their appointment as directors
of UBICS.
 
COMPENSATION OF DIRECTORS
 
     The Company pays each director who is not an executive officer an annual
retainer of $20,000, and all directors are reimbursed for travel expenses
incurred in connection with attending board and committee meetings. Directors
are not entitled to additional fees for serving on committees of the Board of
Directors. In addition, under the 1997 Plan, Mr. Price was granted options to
purchase 20,000 shares of Common Stock at an exercise price of $13.63 per share
upon his appointment as a director.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Mr. Mallya, Chairman and the beneficial owner of approximately 62% of the
outstanding shares of Common Stock of the Company, may also deemed to be in
"control" (within the meaning of the Securities Act) of each company that is a
member of the UB Group. The UB Group is a multinational group of companies
headquartered in India, and Mr. Mallya is Chairman and a significant shareholder
of such companies. Any transaction between the Company, on the one hand, and a
company in the UB Group, on the other hand, may be deemed to be a transaction
between "affiliates" (within the meaning of the Securities Act). In addition,
Mr. Hira, currently President and a director of the Company, was employed in
various senior management capacities with the UB Group and its affiliate, UB
Information Consultancy Services Ltd., an Indian corporation ("UB Services")
from 1981 to 1995, and Mr. Nalavadi, Senior Vice President, Chief Financial
Officer and currently a director of the Company, was employed in various senior
management capacities with the UB Group from 1984 to 1997. See "ELECTION OF
DIRECTORS."
 
     From time to time, the UB Group has provided certain services to the
Company, primarily involving the provision of administrative services to the
Company by UB Group employees and allowing the Company the use of certain office
space and facilities in locations where the UB Group has an office. Prior to
1997, such services were provided on an informal basis and not under a written
contractual arrangement, although the Company reimbursed the UB Group for any
out-of-pocket cost of the services provided.
 
     The aggregate annual value of the services provided by the UB Group to the
Company was less than $10,000 in 1998. In October 1997 the Company entered into
Services Agreements with Mr. Mallya and certain UB Group companies (the
"Services Agreements") pursuant to which the UB Group will provide services and
accommodations to the Company, including the right to use the "UB Group" name,
both in India and in other countries where the UB Group has an office or
location, from time to time on an as needed basis. The Services Agreements,
which have an initial term of five years, require the Company to pay the UB
Group company providing the services or accommodations compensation on terms no
less favorable to the Company than those which would be made to non-affiliated
parties. Compensation for services will be based on the estimated costs,
including a reasonable allocation of direct and indirect overhead costs,
incurred by the UB Group company providing the services. Compensation for use of
facilities of a UB Group company will be based on the provider's costs
(including rent, taxes, utilities and other operating expenses) for the portion
of the facility used by the Company, prorated based on the number of days of
each month the Company actually uses the facility. The costs incurred by the
Company in the future pursuant to these agreements are expected to be comparable
to the costs incurred for such services for prior fiscal years.
 
     The Company also has entered into non-competition agreements with Mr.
Mallya and certain UB Group companies pursuant to which the UB Group (including
UB Services) and Mr. Mallya have agreed not, and to cause their respective
affiliates not, to compete with the Company or use the name "UBICS" and to cause
UB Services to cease business operations. Each non-competition agreement has a
term of five years subject to earlier termination upon certain events involving
a change in control of the Company.
