                    ACQUISITION AND STOCK EXCHANGE AGREEMENT


         This Agreement is made as of March 18, 1999 among UBICS, INC., a
Delaware corporation ("UBICS"), R SYSTEMS, INC., a California corporation ("R
SYSTEMS") SATINDER SINGH REKHI and HARPREET K. REKHI, husband and wife, residing
in Rancho Cordova, California (together "REKHI") and the shareholders of R
Systems listed on the signature page hereof (the "R SYSTEMS SHAREHOLDERS"). R
Systems and Rekhi are collectively referred to herein as the "R SYSTEMS
PARTIES." Concurrently with the execution and delivery of this Agreement, the
parties are delivering a Disclosure Schedule containing certain disclosures
about the parties. References in this Agreement to any "SCHEDULE" are to the
various schedules contained in the Disclosure Schedule.

                                    PREAMBLE

         The Boards of Directors of UBICS and R Systems deem it advisable and in
the best interests of their respective stockholders to consummate (1) the
acquisition of R Systems by UBICS upon the terms and subject to the conditions
set forth herein and (2) the acquisition of R Systems (Singapore) Pte Limited, a
Singapore company ("R SYSTEMS-SINGAPORE"), and R Systems (India) Private
Limited, an Indian corporation ("R SYSTEMS-INDIA"), both of which are affiliated
with R Systems, by UBICS upon the terms and conditions set forth in separate
Acquisition and Stock Exchange Agreements to be executed of even date herewith
and in conjunction herewith (the "RELATED ACQUISITION AGREEMENTS").

         The Boards of Directors of UBICS and R Systems have each, in light of
and subject to the terms and conditions set forth herein, (i) determined that
the Exchange (as defined below) is fair to and in the best interests of their
respective stockholders and corporations, and (ii) adopted resolutions approving
and adopting this Agreement and the transactions contemplated hereby and
recommending the approval and adoption by the stockholders of UBICS and R
Systems, respectively, of this Agreement and the Exchange.

         The parties desire to structure the Exchange as a tax-free
reorganization within the meaning of Section 368(a)(1)(B) of the Internal
Revenue Code of 1986, as amended (together with the rules and regulations
promulgated thereunder, the "CODE"), and desire that the Exchange be accounted
for as a pooling of interests pursuant to generally accepted accounting
principles ("GAAP").

         UBICS would not be willing to enter into this Agreement unless the R
Systems Shareholders agreed to refrain from competing with UBICS, R Systems, R
Systems-Singapore and R Systems-India (collectively, the "COMBINED COMPANIES")
for a 

<PAGE>   7


reasonable period of time, and accordingly each of the R Systems Shareholders
has agreed to execute and deliver to UBICS a noncompetition agreement.

         In conjunction with the execution and delivery of this Agreement and as
an inducement to the R Systems Parties' willingness to enter into this
Agreement, United Breweries Information Consultancy Services Ltd., the owner of
approximately 62% of the outstanding shares of UBICS Common Stock (as defined
below), has agreed to enter into the Voting Agreement with R Systems attached
hereto as Exhibit A (the "VOTING AGREEMENT").

         Therefore, in consideration of the premises and the mutual covenants,
agreements, representations, and warranties herein contained, the parties
hereto, intending to be legally bound, agree as follows.


                                    ARTICLE I
                                    EXCHANGE

         1.01. Exchange. The parties desire to engage in a tax-free
stock-for-stock exchange under Section 368(a)(1)(B) of the Code, for the purpose
of developing and enhancing the parties' respective businesses. Therefore, on
the Closing Date (as defined below), the R Systems Shareholders, will exchange
all of their shares of R Systems Common Stock (as defined below) for shares of
UBICS Common Stock upon the terms and subject to the conditions set forth below
(the "EXCHANGE").

         1.02. Exchange of Shares. At and as of the Closing Date:

                  (a) The R Systems Shareholders will transfer and deliver to
UBICS all of the shares of R Systems' common stock, no par value (the "R SYSTEMS
COMMON STOCK") issued and outstanding immediately prior to the Closing Date in
exchange for 4,718,000 shares (the "EXCHANGE SHARES") of UBICS' common stock,
par value $.01 per share (the "UBICS COMMON STOCK"), such Exchange Shares to be
apportioned among the R Systems Shareholders as set forth on Annex 1.02(a)
hereto;

                  (b) upon the surrender by the R Systems Shareholders of
certificates (or evidence of lost certificates reasonably acceptable to UBICS)
representing all of the outstanding shares of R Systems Common Stock to UBICS,
UBICS shall (i) deliver to the R Systems Shareholders certificates representing
4,246,200 of the Exchange Shares and (ii) deposit into the Escrow (as defined
below), certificates representing 471,800 of the Exchange Shares to secure the
obligations of Rekhi under Article VII below (the "HOLDBACK ESCROW SHARES"). The
Holdback Escrow Shares shall be held in and released from Escrow as and to the
extent provided in the Escrow Agreement among UBICS, Rekhi and Capital City
Escrow, Inc. as escrow agent (the "ESCROW AGENT"), in substantially the form
attached hereto as Exhibit B (the "ESCROW AGREEMENT");


                                      -2-
<PAGE>   8


                  (c) all of the shares of UBICS Common Stock previously issued
and outstanding shall remain issued and outstanding and shall not be affected by
the Exchange; and

                  (d) the Exchange Shares to be issued to the R Systems
Shareholders will not at the time of issuance be registered under the Securities
Act of 1933, as amended (the "SECURITIES ACT"), on the ground that the issuance
thereof in the Exchange is exempt from registration pursuant to Section 4(2)
thereof and/or Regulation D thereunder. The parties understand that the
availability of such exemption is based in part upon the imposition of
restrictions on the transfer of the Exchange Shares, upon certain information
supplied to UBICS by R Systems, the R Systems Shareholders and upon the
representations of the R Systems Parties and the R Systems Shareholders set
forth in this Agreement. The Exchange Shares may not be transferred except
pursuant to an effective registration statement under the Securities Act or an
exemption from such registration requirements and compliance with applicable
state securities law. The following legend will be placed on the certificates
representing the Exchange Shares:

                  THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT
         BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR ANY STATE
         SECURITIES LAWS, AND SUCH SHARES MAY NOT BE SOLD, ENCUMBERED OR
         OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
         STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR AN
         EXEMPTION FROM SUCH REGISTRATION REQUIREMENT, AND, IF AN EXEMPTION
         SHALL BE APPLICABLE, THE HOLDER SHALL HAVE DELIVERED AN OPINION OF
         COUNSEL REASONABLY ACCEPTABLE TO THE COMPANY THAT SUCH REGISTRATION IS
         NOT REQUIRED.

         UBICS may instruct its transfer agent to place stop transfer orders
against any transfer of the Exchange Shares in violation of this subsection (d).

         1.03. The Combined Companies After The Exchange. Effective on the
Closing Date (as defined below):

                  (a) UBICS shall operate under the name RUBICS Solutions, shall
amend its certificate of incorporation to change its corporate name to "RUBICS
Solutions, Inc." and shall relocate its principal corporate offices to the
offices of R Systems in El Dorado Hills, California;

                  (b) the Board of Directors and corporate officers of UBICS and
R Systems will consist of the individuals listed on Annex 1.03(b); and


                                      -3-

Companies or the R Systems Shareholders take, nor will they allow any of their
Affiliates to take, any action which would violate the pooling criteria set
forth in APB Opinion No. 16, thereby affecting the ability of the R Systems
Companies and UBICS to account for the business combination to be effected
pursuant to the Transaction Documents as a pooling of interests. R Systems
hereby affirms and agrees to the matters set forth in Annex 2.31.

         4.06. UBICS Securities Matters and Financial Statements.

                  (a) UBICS has filed with the SEC, and has heretofore made
available to the R Systems Parties true and complete copies of, all forms,
reports, schedules, statements and other documents required to be filed by it
and its Subsidiaries since September 1, 1997 under the Exchange Act or the
Securities Act (as such documents have been amended since the time of their
filing, collectively, the "UBICS SEC DOCUMENTS"), which are all the documents
(other than preliminary material) that UBICS, or any present or former
Subsidiary of UBICS, was required to file with the SEC since such date. As of
their respective filing dates, the UBICS SEC Documents complied in all material
respects with the requirements of the Exchange Act or the Securities Act, as the
case may be, and the rules and regulations of the SEC thereunder applicable to
the UBICS SEC Documents. As of their respective dates or, if amended, as of the
date of the last such amendment, the UBICS SEC Documents, including, without
limitation, any financial statements or schedules included therein did not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

                  (b) The financial statements (including the related notes) of
UBICS included in the UBICS SEC Documents (the "UBICS FINANCIAL STATEMENTS")
comply as to form in all material respects with all applicable accounting
requirements and with the published rules and regulations of the SEC with
respect thereto, present fairly the financial condition of UBICS and its
consolidated Subsidiaries as at the end of the periods covered thereby and the
results of its consolidated operations and the changes in its consolidated cash
flows for the periods covered thereby, and were prepared in accordance with GAAP
applied on a consistent basis throughout the periods covered thereby subject, in
the case of the unaudited interim statements, to year-end audit adjustments
(which are not expected to be material except as otherwise disclosed on Schedule
4.06) and the lack of footnotes and other presentation items. Except as and to
the extent otherwise disclosed in the UBICS Financial Statements or on Schedule
4.06, UBICS and its consolidated Subsidiaries have no liabilities of any kind,
whether direct or indirect, fixed or contingent or otherwise, other than (y)
liabilities which are not required to be set forth on the UBICS Financial
Statements in accordance with GAAP, and (z) liabilities incurred in the ordinary
course of business since September 30, 1998 (the "UBICS FINANCIAL STATEMENT
DATE").

         4.07. Pooling Matters. To UBICS' best knowledge, UBICS has not taken,
nor has it permitted any of its Affiliates to take, nor will it take or allow
any of its Affiliates to take, any action which would violate the pooling
criteria set forth in APB Opinion No. 16, thereby affecting the ability of the R
Systems Companies and UBICS to account for the business combination to be
effected pursuant to the Transaction Documents as a pooling of interests.

agreement with such other party (which UBICS determines in good faith, after
consultation with outside counsel, is required to be executed in order for the
Board of Directors to act in accordance with its fiduciary duties to
stockholders imposed by law), UBICS keeps R Systems informed of the status (not
the terms) of any such discussions or negotiations.

                  "UBICS ACQUISITION PROPOSAL," shall mean any bona fide
proposal, whether in writing or otherwise, made by a third party to acquire
beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) of all or
a material portion of the assets of, or any material equity interest in, UBICS

Thereafter, neither UBICS, R Systems nor any of their respective Affiliates
shall issue or cause the publication of any press release or other public

                                      -41-
<PAGE>   47


(which shall not be unreasonably withheld or delayed), except as may be required
by law or by the NASDAQ National Market ("NASDAQ"), in which case each party
will use reasonable efforts to consult with the other parties prior to any such
issuance.

         5.05. HSR Act Compliance. Promptly following the execution of this
Agreement, the parties to this Agreement shall, if required to do so, file with
the United States Federal Trade Commission (the "FTC") and the United States
Department of Justice (the "DOJ") the notification and report form required for
the transactions contemplated hereby and any supplemental information requested
in connection therewith pursuant to the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended (the "HSR ACT"). Any such notification and report form
and supplemental information shall be in substantial compliance with the
requirements of the HSR Act. Each of the parties to this Agreement shall
cooperate fully with the other parties and furnish to the other parties such
necessary information and reasonable assistance as the other parties may request
in connection with the preparation of any filing or submission which is
necessary under the HSR Act. Each of the parties to this Agreement shall keep
each other party apprised of the status of any communications with, and
inquiries or requests for additional information addressed to the entity that
filed a notification and report form as an acquired or acquiring person from,

comply promptly with any such inquiry or request. Each of the parties to this
Agreement shall use commercially reasonable efforts to obtain any clearance
required under the HSR Act for the transactions contemplated herein.

         5.06. Stockholders Meeting. As soon as practicable after the date
hereof, UBICS, acting through its Board of Directors, shall, in accordance with
applicable Governmental Rules, the rules and regulations of Nasdaq, and its
by-laws, duly call, give notice of, convene and hold a Stockholders Meeting of
UBICS' stockholders (the "STOCKHOLDERS MEETING") for the purpose of considering
and taking action upon this Agreement and the Transactions contemplated hereby.
The Board of Directors of UBICS will recommend to the stockholders of UBICS the
approval of this Agreement and the Transactions contemplated hereby, unless such
Board determines, in good faith, in connection with an Acquisition Proposal,
after consultation with outside counsel, that such action would be inconsistent
with its fiduciary duties to stockholders as required by law and, if such
determination is made, will give written notice to R Systems of such
determination within two business days of the making of such determination. Upon
the issuance of such written notice to R Systems, and upon the written election
of R Systems, UBICS will negotiate in good faith with R Systems for a period of
two business days regarding such adjustments in the terms of the Exchange as
would enable the Board of Directors of UBICS, consistent with its fiduciary
duties to the stockholders, to proceed to recommend the Exchange to the
stockholders of UBICS as contemplated in this Agreement, provided, that there
shall be no obligation, express or implied, on the part of R Systems to agree to
any terms or conditions which may be different from those set forth in this
Agreement.

Affiliates and their respective officers, directors, employees, agents, and

of or in connection with any of the following:

                  (a) any breach of or any inaccuracy in any representation or

<PAGE>   58


         7.04. Claims. The provisions of this Section shall be subject to 
Section 7.05. As soon as is reasonably practicable after becoming aware 
of a claim for indemnification under this Agreement, the party claiming
indemnification from the other party (the "INDEMNIFIED PERSON") shall promptly
give notice to the party from whom indemnification is requested (the
"INDEMNIFYING PERSON") (and, if a UBICS Indemnified Party is the Indemnified
Person, the Escrow Agent) of such claim and the amount the Indemnified Person
will be entitled to receive hereunder from the Indemnifying Person; provided,
however that the failure of the Indemnified Person to give notice shall not
relieve the Indemnifying Person of its obligations under this Article VII,
except to the extent (if any) that the Indemnifying Person shall have been
prejudiced thereby. If the Indemnifying Person does not object in writing to
such indemnification claim within 30 calendar days of receiving notice thereof,
the Indemnified Person shall be entitled to recover from the Indemnifying Person
(and, if a UBICS Indemnified Party is the Indemnified Person, the Escrow Agent)
within five Business Days after such 30 day period, the amount of such claim
(but such recovery shall not limit the amount of any additional indemnification
to which the Indemnified Person may be entitled pursuant to Section 7.02 or
7.03). If the Indemnifying Person agrees that it has an indemnification
obligation, but objects in writing that it is obligated to pay only a lesser
amount, the Indemnified Person shall nevertheless be entitled to recover from
the Indemnifying Person (and, if a UBICS Indemnified Party is the Indemnified
Person, the Escrow Agent) within five Business Days of the receipt of such
objection, the lesser amount, without prejudice to the Indemnified Person's
claim for the difference.

         7.05. Notice of Third Party Claims; Assumption of Defense. The
Indemnified Person shall give notice as promptly as is reasonably practicable to
the Indemnifying Person (and, if the Indemnified Person is a UBICS Indemnified
Party and the Escrow continues to be held by the Escrow Agent, the Escrow Agent)
of the assertion of any claim, or the commencement of any suit, action or
proceeding, by any person not a party hereto in respect of which indemnity may
be sought under this Agreement; provided, however that the failure of the
Indemnified Person to give notice shall not relieve the Indemnifying Person of
its obligations under this Article VII, except to the extent (if any) that the
Indemnifying Person shall have been prejudiced thereby. The Indemnifying Person
may, at its own expense participate in the defense of any claim, suit, action or
proceeding, provided, however that (i) the Indemnifying Person's counsel is
reasonably satisfactory to the Indemnified Person, and (ii) the Indemnifying
Person shall thereafter consult with the Indemnified Person upon the Indemnified
Person's reasonable request for such consultation from time to time with respect
to such claim, suit, action or proceeding. If the Indemnifying Person assumes
such defense, the Indemnified Person shall have the right (but not the
obligation) to participate as counsel of record in the defense thereof and to
employ counsel, at its own expense, separate from the counsel employed by the
Indemnifying Person. If, however, the Indemnified Person reasonably determines
in its judgment that representation by the Indemnifying Person's counsel of both
the Indemnifying Person and the Indemnified Person would 


                                      -53-
<PAGE>   59


present such counsel with a conflict of interest, then such Indemnified Person
may employ separate counsel to represent or defend it in any such claim, action,
suit or proceeding, and the Indemnifying Person shall pay the fees and
disbursements of such separate counsel. Whether or not the Indemnifying Person
chooses to defend or prosecute any such claim, suit, action or proceeding, all
of the parties hereto shall cooperate in the defense or prosecution thereof.

         7.06. Settlement or Compromise. Any settlement or compromise made or
caused to be made by the Indemnified Person or the Indemnifying Person, as the
case may be, of any such claim, suit, action or proceeding of the kind referred
to in Section 7.05 shall also be binding upon the Indemnifying Person or the
Indemnified Person, as the case may be, in the same manner as if a final
judgment or decree had been entered by a court of competent jurisdiction in the
amount of such settlement or compromise; provided, however that no obligation,
restriction or Loss shall be imposed on the Indemnified Person as a result of
such settlement without its prior written consent. The party defending the claim
shall give the other party at least 30 calendar days' notice of any proposed
settlement or compromise of any claim, suit, action or proceeding it is
defending, during which time the other party may reject such proposed settlement
or compromise; provided, however that from and after such rejection, the other
party shall be obligated to assume the defense of and full and complete
liability and responsibility for such claim, suit, action or proceeding and
shall be responsible for any and all Losses in connection therewith in excess of
the amount of the proposed settlement amount.

         7.07. Failure of Indemnifying Person to Act. In the event that the
Indemnifying Person does not elect to assume the defense of any claim, suit,
action or proceeding, then any failure of the Indemnified Person to defend or to
participate in the defense of any such claim, suit, action or proceeding or to
cause the same to be done, shall not relieve the Indemnifying Person of its
obligations hereunder.

         7.08. Escrow. If during the duration of the Escrow Agreement, a UBICS
Indemnified Party is entitled to receive an indemnification amount from Rekhi
pursuant to this Agreement, such amount shall be satisfied to the extent
possible by a transfer to the UBICS Indemnified Party by the Escrow Agent of a
portion of the Holdback Escrow Shares, pursuant to the Escrow Agreement.
Likewise, if during the duration of the Escrow Agreement, Rekhi is entitled to
receive any indemnification amount pursuant to this Agreement, such amount shall
be satisfied by the issuance by UBICS of shares of UBICS Common Stock. The
number of shares of UBICS Common Stock to be transferred by the Escrow Agent to
the UBICS Indemnified Party, or by UBICS to Rekhi, shall be based on a value of
per share equal to the closing sales price of the shares of UBICS Common Stock
as reported on Nasdaq on the Closing Date (the "CLOSING PRICE"). Pursuant to the
Escrow Agreement, the remaining balance of the Holdback Escrow Shares shall be
released to Rekhi on the earlier of the close of business on (i) the first
anniversary of the Closing Date or (ii) the date that the first post-Closing
audit of the Combined Companies is completed (the "ESCROW TERMINATION DATE"),



                                      -54-
<PAGE>   60

except if and to the extent claims have been asserted by UBICS against Rekhi, in
which case an appropriate portion of the Holdback Escrow Shares shall remain in
Escrow until such claims are finally resolved.

         7.09. Duration of Indemnification Obligations. Claims for
indemnification under this Article may only be asserted until the Escrow
Termination Date.

         7.10. Indemnification Threshold and Cap.

                  (a) Notwithstanding any other provision hereof, neither UBICS,
on one hand, nor Rekhi, on the other hand, shall have any indemnification
obligations under this Article unless and until the claims asserted against such
party exceed $175,000 in the aggregate (the "THRESHOLD AMOUNT"); thereafter,
such party shall be liable for all indemnification claims properly asserted
against it, including those comprising the Threshold Amount.

                  (b) The maximum aggregate indemnification obligations of Rekhi
under Section 7.02 and of UBICS under Section 7.03, shall in each case, not
exceed 30% of the product of (i) the total number of Exchange Shares times (ii)
the Closing Price.


                                  ARTICLE VIII
                            MISCELLANEOUS PROVISIONS

         8.01. Filing Fees. UBICS and R Systems shall share equally the HSR
filing fee. All other fees shall be borne by the party responsible therefor.

         8.02. Amendments. This Agreement may be amended only by a writing
signed by each of the parties, and any such amendment shall be effective only to
the extent specifically set forth in such writing.

         8.03. Assignment. Neither this Agreement nor any right, interest or
obligation hereunder may be assigned, pledged or otherwise transferred by any
party, whether by operation of law or otherwise, without the prior consent of
the other party or parties.

         8.04. Counterparts; Telefacsimile Execution. This Agreement and all
agreements, certificates and documents to be delivered in connection herewith
(each an "INSTRUMENT") may be executed in any number of counterparts, and by
each of the parties on separate counterparts, each of which, when so executed,
shall be deemed an original, but all of which shall constitute but one and the
same instrument. Delivery of an executed counterpart of an Instrument by
telefacsimile shall be equally as effective as delivery of a manually executed
counterpart of an Instrument. Any party delivering an executed counterpart of an
Instrument by telefacsimile also shall deliver a manually executed counterpart
of such Instrument, but the failure to deliver a manually executed 


                                      -55-

counterpart shall not affect the validity, enforceability or binding effect of
such Instrument.

contains the entire agreement of the parties with respect to the transactions
contemplated hereby and supersedes all prior written and oral agreements, and
all contemporaneous oral agreements, relating to such transactions.

         8.06. Expenses. Except as otherwise specifically provided herein or in
any other Transaction Document, each party shall be responsible for such
expenses as it may incur in connection with the negotiation, preparation,

perform such additional acts and execute and deliver such additional documents
and instruments as may be required by applicable Governmental Rules or
reasonably requested by any party to establish, maintain or protect its rights
and remedies or to effect the intents and purposes of this Agreement and the
other Transaction Documents. Without limiting the generality of the foregoing,
each party agrees to endorse (if necessary) and deliver to the other, promptly
after its receipt thereof, any payment or document which it receives after the
Closing Date and which is the property of the other.

         8.08. Governing Law. This Agreement shall be a contract under the laws
of the State of Delaware and for all purposes shall be governed by and construed
and enforced in accordance with the laws of said State without giving effect to
the principles of conflicts of law thereof or of any other jurisdiction.

         8.12. Termination.

                  (a) This Agreement may be terminated at any time prior to the
Closing:

                           (i) by mutual agreement of UBICS, R Systems and the R
Systems Shareholder;

                           (ii) by UBICS if there has been a material
misrepresentation by the R Systems Parties hereunder or a material breach by the
R Systems Parties of any of their warranties set forth herein, a material breach
by the R Systems Parties of any of their covenants set forth herein or if any of
the conditions specified in Section 6.02 shall not have been fulfilled within
the time required and shall not have been waived by UBICS;

                           (iii) by R Systems if there has been a material
misrepresentation by UBICS hereunder or a material breach by UBICS of any of its
warranties set forth herein, a material breach by UBICS of any of its covenants
set forth herein or if any of the conditions specified in Section 6.03 shall not
have been fulfilled within the time required and shall not have been waived by R
Systems; or

                           (iv) by UBICS or R Systems if the Closing shall not
have occurred prior to June 30, 1999; provided, that UBICS or R Systems may
terminate this Agreement pursuant to this subparagraph only if the Closing shall
not have occurred on or prior to such date for a reason other than a failure by
such party to satisfy the conditions to Closing of the other party set forth in
Section 6.02 or 6.03.

                  (b) If this Agreement is terminated by either R Systems or

or liabilities hereunder except for obligations or liabilities arising from a
breach of this Agreement prior to such termination or which survive such
termination by their own terms and except for obligations under confidentiality
agreements between UBICS and R Systems. Notwithstanding the foregoing, the
maximum amount of damages that may be recovered with respect to any breach of
this Agreement which results in termination of this Agreement prior to closing
is an aggregate of $500,000, which amount, the parties agree, shall constitute
liquidated damages for such breach.

         8.13. Waivers. The due performance or observance by the parties of
their respective obligations hereunder and under the other Transaction Documents
shall not be waived, and the rights and remedies of the parties hereunder and
under the other Transaction Documents shall not be affected, by any course of
dealing or performance or by any delay or failure of any party in exercising any
such right or remedy. The due performance or observance by a party of any of its
obligations hereunder or under any other Transaction Document may be waived only
by a writing signed by the party 


                                      -58-
<PAGE>   64


against whom enforcement of such waiver is sought, and any such waiver shall be
effective only to the extent specifically set forth in such writing.

         8.14 Arbitration. Any claim, controversy or dispute arising between the
parties with respect to this Agreement (a "DISPUTE"), to the maximum extent
allowed by applicable law, shall be submitted to and finally resolved by binding
arbitration. Either party may file a written Demand for Arbitration with the
American Arbitration Association's Sacramento, California Regional Office, and
shall send a copy of the Demand for Arbitration to the other party. The
arbitration shall be conducted pursuant to the terms of the Federal Arbitration
Act and the Commercial Arbitration Rules of the American Arbitration
Association, except that discovery may be had in accordance with the Federal
Rules of Civil Procedure. The venue for the arbitration shall be the Sacramento,
California office of the American Arbitration Association. The arbitration shall
be conducted before a panel of three arbitrators selected as follows:. Within 15
business days after a Demand for Arbitration is filed, each party shall select
an arbitrator and, within 10 business days after the end of such 15-day period,
such two arbitrators shall select a third arbitrator. Each arbitrator must
either have professional experience relating to the business or legal aspects of
the subject of the arbitration or be a retired judge. No arbitrator shall (i)
have any material interest in the result of the arbitration or (ii) be, or shall
ever have been, an Affiliate, equity holder or creditor of, or an attorney,
accountant, agent or consultant for, any party to such arbitration proceeding.
The arbitrators shall meet promptly, fix the time, date and place of the hearing
and notify the parties. The parties shall stipulate that the arbitration hearing
shall last no longer than five business days. A majority of the panel shall
render a decision within 10 days of the completion of the hearing, which
decision may include an award of legal fees, costs of arbitration and interest.
The panel of arbitrators shall promptly transmit an executed copy of its
decision to the parties. The decision of the arbitrators shall be final, binding
and conclusive upon the parties. Each party shall have the right to have the
decision enforced by any court of competent jurisdiction. Notwithstanding any
other provision of this Section, any Dispute in which a party seeks equitable
relief may be brought in any court having jurisdiction. The obligations of the
parties under this Section shall be specifically enforceable and shall survive
any termination of this Agreement.

                                VOTING AGREEMENT


         This Agreement is made as of March 18, 1999 by and among UBICS, INC., a
Delaware corporation ("UBICS"), R SYSTEMS, INC., a California corporation ("R
SYSTEMS") and UNITED BREWERIES INFORMATION CONSULTANCY SERVICES LTD., a British
Virgin Islands corporation (the "STOCKHOLDER").

                                    PREAMBLE

         UBICS has entered into separate Acquisition and Stock Exchange
Agreements dated as of the date hereof (as the same may be amended or
supplemented, the "ACQUISITION AGREEMENTS"; capitalized terms used but not
defined herein shall have the meanings set forth in the Acquisition Agreements)
providing for the acquisition of all of the outstanding stock of R Systems, Inc.
and its related companies, R Systems (India) Private Limited and R Systems
(Singapore), (collectively, the "R SYSTEMS COMPANIES"), by UBICS (the
"ACQUISITIONS"), upon the terms and subject to the conditions set forth in the
Acquisition Agreements.

         The Stockholder owns 4,033,751 shares of UBICS Common Stock (such
shares of UBICS Common Stock, together with any other shares of capital stock of
UBICS acquired by the Stockholder after the date hereof and during the term of
this Agreement as set forth below, being collectively referred to herein as the
"SUBJECT SHARES").

         As a condition to their willingness to enter into the Acquisition
Agreements, the R Systems Companies and their shareholders have requested that
the Stockholder enter into this Agreement.

         Therefore, to induce the R Systems Companies and their shareholders to
enter into, and in consideration of their entering into, the Acquisition
Agreements, and intending to be legally bound, the parties agree as follows:

         1. Representations and Warranties of the Stockholder. The Stockholder
represents and warrants as follows:

                  (a) Authority. The Stockholder has all requisite power and
authority to enter into this Agreement and to consummate the transactions
contemplated hereby. This Agreement has been duly and validly authorized,
executed and delivered by the Stockholder and constitutes a legal, valid and
binding obligation of the Stockholder enforceable in accordance with its terms
(except as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' rights generally
or by the principles governing the availability of equitable remedies). The
execution, delivery and performance of this Agreement do not, and the


<PAGE>   77


consummation of the transactions contemplated hereby and compliance with the
terms hereof will not, conflict with, breach, or result in any violation of, or
default (with or without notice or lapse of time or both) under any provision
of, any trust agreement, loan or credit agreement, note, bond, mortgage,
indenture, lease or other agreement, instrument, permit, concession, franchise,
license, judgment, order, notice, decree, statute, law, ordinance, rule or
regulation applicable to the Stockholder or to the Stockholder's property or
assets.

                  (b) The Subject Shares. The Stockholder is the record and
beneficial owner of, and has good and marketable title to, the Subject Shares,
free and clear of any claims, liens, options, charges, or other encumbrances and
security interests except as set forth on Schedule 1(b) hereto. As of the date
hereof, the Stockholder does not own, of record or beneficially, any shares of
capital stock of UBICS other than the Subject Shares. The Stockholder has the
sole right to vote such Subject Shares, and none of the Subject Shares is
subject to any voting trust or other agreement, arrangement or restriction with
respect to the voting of the Subject Shares, except as contemplated by this
Agreement.

         2. Agreement to Vote Shares. Until the termination of this Agreement in
accordance with Section 7, at every meeting of stockholders of UBICS called to
vote upon the Acquisitions and the Acquisition Agreements or at any adjournment
thereof or in every other circumstance upon which a vote, consent or other
approval (including by written consent) with respect to the Acquisitions and the
Acquisition Agreements is sought, the Stockholder shall, including by executing
a written consent if requested by UBICS, vote (or cause to be voted) the Subject
Shares in favor of the Acquisitions, the adoption by UBICS of the Acquisition
Agreements, the approval of the terms thereof and each of the other transactions
contemplated by the Acquisition Agreements and any matter that could reasonably
be expected to facilitate the Acquisitions. The Stockholder agrees to refrain
from (a) voting at any annual or special meeting of the stockholders of UBICS in
any manner inconsistent with the terms of this Agreement, (b) executing any
written consent in lieu of a meeting of the stockholders of UBICS in any manner
inconsistent with the terms of this Agreement, (c) granting any proxy or
authorization to any person with respect to the voting of the Subject Shares, or
taking any action contrary to or in any manner inconsistent with the terms of
this Agreement. Until after the Acquisitions are consummated or the Acquisition
Agreements are terminated, the Stockholder shall use all reasonable efforts to
take, or cause to be taken, all actions, and to do, or cause to be done, and to
assist and cooperate with the other parties in doing, all things necessary,
proper or advisable to consummate and make effective, in the most expeditious
manner practicable, the Acquisitions and the other transactions contemplated by
the Acquisition Agreements.

         3. Additional Share Purchases. The Stockholder agrees that any shares
of capital stock of UBICS that the Stockholder purchases or with respect to
which the Stockholder otherwise acquires beneficial ownership after the
execution of this 



                                       2
<PAGE>   78


Agreement and prior to termination of this Agreement under Section 7 shall be
subject to the terms and conditions of this Agreement to the same extent as if
they constituted Subject Shares.

         4. Irrevocable Proxy. Concurrently with the execution of this
Agreement, the Stockholder agrees to deliver to the R Systems Companies a proxy
in the form attached hereto as Exhibit A (the "PROXY"), which shall be
irrevocable, with the total number of shares of capital stock of UBICS
beneficially owned by the Stockholder set forth therein.

         5. Further Assurances. The Stockholder will, from time to time, execute
and deliver, or cause to be executed and delivered, such additional or further
consents, documents and other instruments as R Systems may reasonably request
for the purpose of effectively carrying out the transactions contemplated by
this Agreement.

         6. Assignment. Neither this Agreement nor any of the rights, interests
or obligations hereunder shall be assigned by any of the parties without the
prior written consent of the other parties. Subject to the preceding sentence,
this Agreement will be binding upon, inure to the benefit of and be enforceable
by the parties and their respective successors and permitted assigns.

         7. Termination. This Agreement shall terminate upon the Closing Date;
provided, however, that if UBICS is not in breach of its obligations under the
Acquisition Agreements and the Stockholder is not in breach of its obligations
under Section 2 of this Agreement, this Agreement shall terminate automatically
if the Acquisition Agreements are terminated pursuant to the terms thereof.

         8. General Provisions.

                  (a) Amendments. This Agreement may not be amended, modified,
altered or supplemented except by an instrument in writing signed by each of the
parties hereto.

                  (b) Notice. All notices and other communications hereunder
shall be in writing and shall be deemed given if delivered personally or sent by
overnight courier (providing proof of delivery) to UBICS and R Systems in
accordance with the Acquisition Agreements and to the Stockholder at 3 Harbor
Drive, Suite 115, Sausalito, California 94965 (or at such other address for a
party as shall be specified by like notice).

                  (c) Counterparts. This Agreement may be executed in one or
more counterparts, all of which shall be considered one and the same agreement,
and shall become effective when one or more of the counterparts have been signed
by each of the 


                                       3
<PAGE>   79


parties and delivered to the other party, it being understood that each party
need not sign the same counterpart.

                  (d) Entire Agreement; No Third-Party Beneficiaries. This
Agreement (including the documents and instruments referred to herein) (i)
constitutes the entire agreement and supersedes all prior negotiations,
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof and (ii) is not intended to confer upon any
person other than the parties hereto any rights or remedies hereunder.

                  (e) Governing Law. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of Delaware regardless of
the laws that might otherwise govern under applicable principles of conflicts of
law thereof.

                  (f) Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, void or unenforceable, then the remainder of the terms, provisions,
covenants and restrictions of this Agreement shall remain in full force and
effect and shall in no way be affected, impaired or invalidated.

         9. Enforcement. The parties agree that irreparable damage would occur
in the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to seek an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in any court of the United States
located in the State of Delaware or in a Delaware state court, this being in
addition to any other remedy to which they are entitled at law or in equity. In
addition, each of the parties hereto (i) consents to submit such party to the
personal jurisdiction of any Federal court located in the State of Delaware or
any Delaware state court in the event any dispute arises out of this Agreement
or any of the transactions contemplated hereby, (ii) agrees that such party will
not attempt to deny or defeat such personal jurisdiction by motion or other
request for leave from any such court, and (iii) agrees that such party will not
bring any action relating to this Agreement or the transactions contemplated
hereby in any court.

individuals residing in Rancho Cordova, California (collectively, the
"SHAREHOLDER"), and CAPITAL CITY ESCROW, INC., as escrow agent (the "ESCROW
AGENT").

                                    PREAMBLE

         UBICS, R Systems, Inc., a California corporation ("R SYSTEMS"), and the
shareholders of R Systems, including the Shareholder, have entered into an
Acquisition and Stock Exchange Agreement dated as of March 18, 1999 (the
"ACQUISITION AGREEMENT"), pursuant to which UBICS is acquiring all of the
outstanding shares of common stock of R Systems in exchange for shares of UBICS
common stock. Section 1.02(b) of the Acquisition Agreement provides for certain
of the Exchange Shares to be placed in an escrow account to secure certain
indemnification obligations of the Shareholder to UBICS under Section 7.02 of
the Acquisition Agreement, on the terms and subject to the conditions set forth
herein (the "ESCROW"). All capitalized terms used but not defined herein shall
have the meanings given to them in the Acquisition Agreement.

         Therefore, in consideration of the premises and the mutual covenants
and agreements contained herein, the parties hereto, intending to be legally
bound, agree as follows:

         1. Establishment of Escrow.

                  (a) UBICS and the Shareholder hereby appoint Escrow Agent to
serve as the escrow agent under and to administer the terms of this Agreement
and Escrow Agent hereby accepts such appointment and agrees to hold the Holdback
Shares subject to the terms and conditions of this Agreement.

                  (b) UBICS and the Shareholder have caused to be deposited with
Escrow Agent the Holdback Escrow Shares, which shall be held by Escrow Agent in
trust for the benefit of UBICS and the Shareholder, and shall be released and
disbursed by Escrow Agent only in accordance with the terms of this Agreement.

         2. Delivery of Holdback Escrow Shares. Simultaneously with the
execution hereof by UBICS, the Shareholder and Escrow Agent, certificates
evidencing the Holdback Escrow Shares shall have been delivered by UBICS to
Escrow Agent along with stock powers duly executed in blank by the Shareholder,
substantially in the form set forth as Attachment A hereto. Escrow Agent hereby
acknowledges receipt of the Holdback Escrow Shares and the executed stock
powers.

           3. Rights in Holdback Escrow Shares. Except as provided herein, all
legal and beneficial ownership rights to the Holdback Escrow Shares shall remain
with the Shareholder during such time as the Holdback Escrow Shares are held by
Escrow Agent, including, but not limited to, any right to vote or to receive
distributions thereon. Notwithstanding the foregoing, certificates evidencing
any shares of UBICS capital stock that are payable with respect to the Holdback
Escrow Shares that have not been released from escrow pursuant to the terms of
this Agreement as a result of any stock dividend, reclassification, stock split,
subdivision or combination of shares, recapitalization or other events generally
made with respect to the UBICS common stock ("ADDITIONAL SHARES") shall be
delivered to Escrow Agent and shall be held in the Escrow. Unless otherwise
indicated, as used in this Agreement, the term "Holdback Escrow Shares" includes
any Additional Shares. Unless and until the Escrow Agent has received such
Additional Shares, it may assume without inquiry that none have been or are
required to be issued.

           Additional Shares issued in respect of Holdback Escrow Shares which
have been released from the Escrow pursuant to the terms of this Agreement shall
not be added to the Escrow but shall be distributed to the record holders of
such released Holdback Escrow Shares, Cash dividends paid with respect to
Holdback Escrow Shares shall not be added to the Escrow but shall be distributed
upon receipt by the Escrow Agent to the Shareholder at his address set forth in
the Acquisition Agreement.

           The Shareholder shall have voting rights with respect to the
Additional Shares. The Escrow Agent need not furnish proxy materials or other
information received by it with respect to the Holdback Escrow Shares to the
Shareholder, it being understood that UBICS will deliver such proxy materials
and other information to the Shareholder.

           4. Release of Holdback Escrow Shares. Escrow Agent agrees to disburse
the Holdback Escrow Shares as follows:

                  (a) Set-Off Shares. Upon receipt by Escrow Agent at any time
on or before the Escrow Termination Date (as hereinafter defined), of a
certificate signed by the Chairman or the chief financial officer of UBICS (a
"CLAIM NOTICE"), (1) stating that Losses exist or are asserted, (2) specifying
in reasonable detail the individual items of such Losses, the date each such
item was paid or incurred (if already paid or incurred) and the nature of the
misrepresentation, breach of warranty or covenant to which such item is related,
(3) stating the dollar amount of such Losses, paid or incurred by UBICS, or if
the amount of Losses has not yet been determined, UBICS' good faith estimate of
the maximum amount of Losses it expects to incur with respect to such item,
which estimate shall not be binding on UBICS, and (4) the number of Holdback
Escrow Shares to be retained, assuming no objections, by Escrow Agent to satisfy
such Losses, Escrow Agent shall, subject to the provisions of this Section 4,
and upon expiration of the 30-day period specified in Section 4(a)(i) hereof and
provided Escrow Agent has not 


                                      -2-
<PAGE>   85


received notice of a Disputed Claim (as defined in Section 4(a)(i), deliver to
UBICS out of the Escrow, as promptly as practicable, Holdback Escrow Shares
having a value (determined in accordance with Section 4(a)(ii) below) equal to
the full amount of such Losses (the "SET-OFF SHARES"). Except as otherwise
provided herein, any claim by UBICS against the Escrow made in a Claim Notice
pursuant to this Section 4 shall be referred to herein as a "CLAIM" or, if
multiple, "CLAIMS." Any delivery of the Set-Off Shares by Escrow Agent is
subject to the following terms and conditions:

                           (i) At the time of delivery of any Claim Notice to
Escrow Agent, UBICS shall cause to be delivered to the Shareholder a duplicate
copy of such notice and for a period of thirty (30) days after receipt by Escrow
Agent of such Claim Notice, Escrow Agent shall make no delivery to UBICS of any
Holdback Escrow Shares pursuant to Section 4(a) unless Escrow Agent shall have
received written authorization from the Shareholder to make such delivery.
Within thirty (30) calendar days of receipt of the Claim Notice from UBICS, the
Shareholder shall either (A) direct Escrow Agent in writing to disburse the
Set-Off Shares to UBICS, or (B) notify UBICS, with contemporaneous delivery to
Escrow Agent, in writing of an intention to dispute the Claim and the basis of
such dispute (a "DISPUTED CLAIM"), including, but not limited to, a dispute on
matters relating to Losses. If the Shareholder fails to make any of the
foregoing elections within such thirty (30) day period, UBICS shall send written
notice of such failure to Escrow Agent, who shall disburse the Set-Off Shares to
UBICS on the next Business Day following the receipt of such written notice. If
the Shareholder elects to dispute the Claim, UBICS and the Shareholder shall
attempt in good faith until thirty (30) calendar days after receipt of the
Disputed Claim to agree upon the rights of the respective parties with respect
to each Claim. If UBICS and the Shareholder should so agree, a memorandum
setting forth such agreement shall be prepared and signed jointly by the
Shareholder and by the Chairman or the chief financial officer of UBICS and
shall be delivered to Escrow Agent. Escrow Agent shall be entitled to rely on
any such memorandum and shall distribute the Set-Off Shares from the Escrow in
accordance with the terms thereof. If UBICS and the Shareholder are unable to
agree, then, subject to Sections 4(b) and 4(c) below, such Holdback Escrow
Shares shall remain subject to the Escrow until such dispute shall be resolved
in accordance with the terms of the Acquisition Agreement. If such resolution is
determined by arbitration under the terms of the Acquisition Agreement, the
decision of a majority of the three arbitrators as to the validity and amount of
any Loss in such officer's certificate and any other matter related to the
Disputed Claim shall be binding and conclusive upon UBICS and the Shareholder
involved in the Disputed Claim, notwithstanding anything in Section 4 hereof.
The arbitrators shall provide a copy of the written decision to Escrow Agent and
Escrow Agent shall be entitled to act in accordance with such written decision
of the arbitrators and to make or withhold distributions of Set-Off Shares in
accordance therewith. Such decision shall be written and shall be supported by
written findings of fact and conclusions which shall set forth the award,
judgment, decree or order awarded by the arbitrators. If such resolution is not
determined by arbitration and is 



                                      -3-
<PAGE>   86


determined by mutual agreement of UBICS and the Shareholder, promptly after such
resolution, UBICS (by either its Chairman or chief financial officer) and the
Shareholder shall jointly execute a written memorandum which sets forth such
resolution and deliver such memorandum to Escrow Agent. Escrow Agent shall be
entitled to rely on any such memorandum and shall distribute the Set-Off Shares
in accordance with the terms thereof.

                           (ii) For purposes of determining the number of
Holdback Escrow Shares equivalent to the dollar value of payments to which
either UBICS or the Shareholder are entitled under this Agreement, the Holdback
Escrow Shares shall be valued at $_______ per share [CLOSING PRICE ON CLOSING
DATE](the "UBICS PRICE PER SHARE").

                           (iii) As a condition to the delivery of the Set-Off
Shares, UBICS shall deliver to Escrow Agent certificates representing the
remaining balance of the Holdback Escrow Shares.

                           (iv) Fractional shares of UBICS Common Stock need not
be issued. Nor shall payments be made in lieu of fractional interests.
Accordingly, each Claim Notice and each officer's certificate delivered to
Escrow Agent pursuant to Section 4(a)(i) shall round up Losses so that an even
number of shares, valued at the UBICS Price Per Share, may be allocated to such
Losses.

                  (b) Release of Escrow. Subject to this Section 4(b), on the
earlier of (i) the first anniversary of the Closing Date or (ii) the date of the
first post-Closing audit of the Combined Companies, both of which will be
certified to Escrow Agent in a certificate jointly signed by the Shareholder and
the Chairman or the Chief Executive Officer of UBICS (the "ESCROW TERMINATION
DATE"), Escrow Agent shall release to the Shareholder all of the Holdback Escrow
Shares deposited in Escrow, less the sum of (i) that number of Holdback Escrow
Shares that shall have been released prior to such date pursuant to the terms
hereof, and (ii) that number of Retained Shares (defined below) together with
corresponding stock powers. In the event that there are any Claims specified in
any Claim Notice previously delivered to Escrow Agent which are unresolved or
are the subject of a Disputed Claim on the Escrow Termination Date, subject to
the objection of the Shareholder as provided herein, Escrow Agent shall retain
in the Escrow that number of Holdback Escrow Shares which are necessary based on
the UBICS Price Per Share, to satisfy any such unsatisfied Claims until such
Claims have been fully and finally resolved (the "RETAINED SHARES"). If the
Shareholder disputes the retention of all or a portion of the Retained Shares,
UBICS and the Shareholder shall attempt in good faith within thirty (30)
calendar days after the Escrow Termination Date (the "RETENTION RESOLUTION
PERIOD") to agree upon the number of Retained Shares. If UBICS and the
Shareholder should so agree, a memorandum setting forth such agreement shall be
prepared and signed by the Shareholder and by the Chairman 



                                      -4-
<PAGE>   87


or chief financial officer of UBICS and shall be delivered to Escrow Agent.
Escrow Agent shall be entitled to rely on any such memorandum and shall
distribute and/or retain such Holdback Escrow Shares in accordance with the
terms thereof. If UBICS and the Shareholder cannot agree within the Retention
Resolution Period, the number of Retained Shares (if any) shall be determined
pursuant to Section 4(c) below.

                  (c) Arbitration. If UBICS and the Shareholder cannot agree
within the Retention Resolution Period, the number of Retained Shares (if any)
shall be determined by arbitration as set forth in Section 21 below. The
decision of a majority of the three arbitrators as to the validity and amount of
Retained Shares to be held in the Escrow shall be binding and conclusive upon
UBICS and the Shareholder involved in the disputed Retained Shares, and
notwithstanding anything in Section 4 hereof. The arbitrators shall provide a
copy of the written decision to Escrow Agent and Escrow Agent shall be entitled
to act in accordance with such written decision of the arbitrators, so long as
such decision shall no longer be or shall not be subject to appeal or review by
lapse of time or otherwise, and to make or withhold distributions of Retained
Shares in accordance therewith. Such decision shall be written and shall be
supported by written findings of fact and conclusions which shall set forth the
award, judgment, decree or order awarded by the arbitrators. If such resolution
is not determined by arbitration and is determined by mutual agreement of UBICS
and the Shareholder, UBICS (on the one hand) and the Shareholder (on the other
hand) shall each be responsible for one half of all fees and costs of the
arbitrators.

                  (d) Joint Release. Notwithstanding the foregoing, Escrow Agent
shall promptly release and disburse the Holdback Escrow Shares pursuant to a
mutual written express agreement to release such shares as directed in any
certificate jointly executed by the Shareholder and the Chairman or chief
financial officer of UBICS.

         5. Transfer of Escrow Shares. UBICS, upon receipt of any Holdback
Escrow Shares (together with corresponding stock powers) shall have full legal
and beneficial ownership of such Holdback Escrow Shares, and may either cancel
such shares, hold them in treasury or reissue them as it deems appropriate.

         6. Termination of Escrow. This Escrow Agreement and the escrow account
created hereby shall terminate upon delivery of all of the Holdback Escrow
Shares pursuant to the terms of Section 4 herein.

         7. Escrow Agent Fees and Expenses. Escrow Agent's fee for serving as
Escrow Agent hereunder shall consist of a $_______ initial fee and a $_______
annual fee for each year of this Agreement, payable on each anniversary of the
date hereof. If for any reason Escrow Agent resigns, Escrow Agent shall refund a
pro rata part of the annual fee based on the number of days in the year that
Escrow Agent has served as such. UBICS (on the one hand) and the Shareholder (on
the other hand) 



                                      -5-
<PAGE>   88


shall each be responsible for one-half of all of Escrow Agent's fees. Further,
Escrow Agent shall be reimbursed equally by UBICS (on one hand) and the
Shareholder (on the other hand) for all reasonable expenses incurred by Escrow
Agent in the performance of its duties hereunder.

         8. Escrow Agent's Duties and Responsibilities.

                  (a) Scope of Undertaking. Escrow Agent's duties and

hold and deliver the property as herein provided. Escrow Agent shall not be
liable for any error in judgment, any act or omission, any mistake of law or

hold and safeguard the Holdback Escrow Shares during the term of the Escrow, and

Agreement and not as the property of UBICS and shall hold and dispose of the
Holdback Escrow Shares only in accordance with the terms hereof.

           9. Reliance; Liability. Escrow Agent may rely on, and shall not be
liable for acting or refraining from acting upon, any written notice,

to be genuine and what it purports to be and to have been signed or presented by
the proper party or parties. Escrow Agent shall be responsible for holding and
disbursing the property held in the Escrow pursuant to this Agreement; provided
that in no event shall Escrow Agent be liable for any lost profits, lost
savings, or other special, exemplary, consequential or incidental damages in
excess of Escrow Agent's fee hereunder, except to the extent such losses or
damages are attributable to the gross negligence or willful misconduct of Escrow
Agent; and 


                                      -6-
<PAGE>   89

of this Agreement or any part hereof or for the transaction or transactions
requiring or underlying the execution of this Agreement, the form or execution
hereof or for the identity or authority of any person executing this Agreement
or any part hereof.

         10. Right of Interpleader. Should any controversy arise involving the
parties hereto or any of them or any other person, firm or entity with respect
to this Agreement, or should a substitute escrow agent fail to be designated as
provided below, or if Escrow Agent receives conflicting demands or claims, or if
Escrow Agent should be in doubt as to what action to take under the terms of
this Agreement, Escrow Agent shall have the right, but not the obligation,
either to (a) withhold delivery of the property until the controversy is
resolved, a substitute escrow agent is properly appointed, the conflicting
demands or claims are withdrawn, or its doubt is resolved or (b) institute a
petition for interpleader in any court of competent jurisdiction to determine
the rights of the parties hereto.

         11. Indemnification. UBICS and the Shareholder hereby jointly and
severally indemnify Escrow Agent, its officers, directors, employees and agents

without limitation, attorneys' fees, and claims, including, but not limited to,
costs of investigation, litigation, arbitration, tax liability or loss on
investments, suffered or incurred by any Indemnified Party in connection with or
arising from or out of this Agreement, except such acts or omissions as may
result from the willful misconduct or gross negligence of such Indemnified
Party.

         12. Resignation and Removal. Escrow Agent may resign hereunder at any
time upon thirty (30) calendar days' prior written notice of resignation to all
of the other parties to this Agreement. Upon the effective date of such
resignation, Escrow Agent shall deliver the Holdback Escrow Shares remaining in
the Escrow at the time of such resignation to any substitute escrow agent
designated by the other parties in writing. The other parties shall designate,
in a writing signed by the Shareholder and the Chairman or Chief Financial
Officer of UBICS and delivered to Escrow Agent, a replacement Escrow Agent
within thirty (30) calendar days of the giving of such notice. If the other
parties fail to designate a substitute escrow agent in a writing signed by both
parties within thirty (30) calendar days after the giving of such notice, Escrow
Agent may institute a petition for interpleader in a court of competent
jurisdiction. Escrow Agent's sole responsibility after such thirty (30) day
notice period expires shall be to hold such Holdback Escrow Shares in safe
keeping and to deliver the same to a designated substitute escrow agent, if any,
or in accordance with the directions of a final order or judgment of a court of
competent jurisdiction, all of which, by lapse of time or otherwise, shall no
longer be or shall not be subject to appeal or review, at which time of delivery
Escrow Agent's obligations hereunder shall cease and terminate. The other
parties may remove and replace Escrow Agent by a writing signed by the Chairman
or chief financial officer of UBICS and the Shareholder designating a
replacement Escrow Agent and delivered to Escrow Agent, and Escrow Agent shall
deliver the Holdback Escrow Shares remaining in the Escrow at the time of such
removal to any designated replacement Escrow Agent selected by the other
parties.

but only in writing signed by Escrow Agent, UBICS (by its Chairman or chief
financial officer) and the Shareholder.

                                   TERMINATION

         2.01 Illness, Incapacity. Subject to the Company's compliance with
applicable laws, if during the term of Employee's employment hereunder Employee

Company, from effectively performing his duties hereunder, for a period of the
lesser of (a) 90 days or (b) the number of days after which benefits would begin

or disability, then the Company may, by written notice to Employee, terminate

together with payment of any compensation set forth in Article I of this
Agreement and benefits accrued under this Agreement, Employee's employment and
all obligations of the Company under Article I hereof shall 



                                      -3-

programs referred to in Section 1.05. The obligations of Employee under Article
IV hereof shall continue notwithstanding termination of Employee's employment
pursuant to this Section 2.01.

         2.02 Death. If Employee dies during the term of his employment
hereunder, Employee's employment hereunder shall terminate and all obligations
of the Company hereunder shall forthwith terminate; provided, however, the

period of six months following the date of Employee's death.

         2.03 Company Termination.

                  (a) For Cause. Employee's employment hereunder may be
terminated at any time by the Company for cause. Termination shall be deemed for
cause if among the reasons therefor are Employee's dishonesty, disloyalty,
willful misconduct, gross negligence or refusal or unwillingness to perform his
duties hereunder in good faith and to the best of his ability. Payment of all
compensation and provision of all benefits to Employee hereunder shall cease to
be effective as of the date of any such termination, except that Employee will
be entitled to all compensation and benefits accrued as of the date of
termination. The obligations of Employee under Article IV hereof shall continue
notwithstanding termination of Employee's employment pursuant to this Section
2.03.

                  (b) Without Cause. Employee's employment hereunder may be
terminated at any time by the Company without cause, provided that upon any such
termination without cause the Company shall pay Employee, subject to Employee's
compliance with all of his obligations hereunder, his full Salary plus employee
benefits for the remainder of the term of this Agreement. In addition, the
Company shall, at Employee's option either (i) pay Employee the full amount
Employee would have received under the terms of the Consulting Agreement or (ii)
enter into the Consulting Agreement with Employee and Employee shall serve as a
consultant pursuant to the terms thereof. The obligations of Employee under
Article IV hereof shall continue notwithstanding termination of Employee's
employment pursuant to this Section 2.03(b).

         2.04 Employee Termination. Employee may terminate his employment
hereunder by giving the Company two months prior written notice of such
termination. Simultaneously with such notice, Employee shall inform the Company
in writing as to his employment plans following the termination of his
employment with the Company. Payment of all compensation and provision of all
benefits to Employee hereunder shall cease to be effective as of the date of any
such termination, except that Employee will be 



                                      -4-
<PAGE>   100


entitled to all compensation and benefits accrued as of the date of termination.
The obligations of Employee under Article IV hereof shall continue
notwithstanding termination of Employee's employment pursuant to this Section
2.04.

         2.05 Effect of Termination on Options. Notwithstanding anything to the
contrary set forth in any stock option plan of the Company or any Stock Option
Agreement between the Company and Employee, in the event of termination of
Employee's employment hereunder for any reason other than for cause due to
Employee's willful misconduct or gross negligence, all stock options held by
Employee shall immediately vest and shall remain exercisable by Employee or
Employee's estate for a period of one year following such termination.

of the parties that the provisions of Section 7 hereof shall be enforceable to

provisions hereof shall not render unenforceable, or impair, the remainder
thereof. If any provision or provisions hereof shall be deemed invalid or

an affiliate, equity holder or creditor of, or an attorney, accountant, agent or
consultant for, any party to such arbitration proceeding. The arbitrators shall
meet promptly, fix the time, date and place of the hearing and notify the
parties. The parties shall stipulate that the arbitration hearing shall last no
longer than five business days. A majority of the panel shall render a decision
within 10 days of the completion of the hearing, which decision may include an

express written consent of the Company. Consultant agrees not to represent to
any person or corporation or other entity that the relationship of Consultant to
the Company is other than that of independent contractor.

                  12. MISCELLANEOUS. The invalidity or unenforceability of any
provision hereof shall in no way affect the validity or enforceability of any
other provision. This Agreement embodies the entire Agreement between the
parties hereto with respect to the subject matter hereof and supersedes any and
all prior or contemporaneous, oral or written understandings, negotiations, or
communications on behalf of such parties. This Agreement may be executed in any
number of counterparts, each of which shall be deemed an original, but all of

party of any breach or violation of any provision of this Agreement shall not
operate or be construed as a waiver of any subsequent breach or violation
hereof. This Agreement is executed in and shall be governed by and construed in
accordance with the laws of the State of Delaware. This Agreement may

Agreement because the Company is in material violation of its obligations under
this Agreement.

                  8. REMEDIES. In the event of a breach by the Consultant of the
terms of this Agreement, the Company shall be entitled, if it shall so elect, to
institute legal proceedings to obtain damages for any such breach, or to enforce
the specific performance of this Agreement by the Consultant and to enjoin the
Consultant from any further violation of this Agreement and to exercise such
remedies cumulatively or in conjunction with all other rights and remedies
provided by law. The Consultant acknowledges, however, that the remedies at law

                  9. AUTHORIZATION TO MODIFY RESTRICTIONS. It is the intention
of the parties that the provisions of Section 7 hereof shall be enforceable to
the fullest extent permissible under applicable law, but that the

provisions hereof shall not render unenforceable, or impair, the remainder
thereof. If any provision or provisions hereof shall be deemed invalid or
unenforceable, either in whole or in part, this Agreement shall be deemed
amended to delete or modify, as necessary, the offending provision or provisions
and to alter the bounds thereof in order to render it valid and enforceable.

                 10. BINDING ARBITRATION. Any claim, controversy or dispute

maximum extent allowed by applicable law, shall be submitted to and finally
resolved by binding arbitration. Either party may file a written Demand for
Arbitration with the American Arbitration Association's Sacramento, California
Regional Office, and shall send a copy of the Demand for Arbitration to the
other party. The arbitration shall be conducted pursuant to the terms of the
Federal Arbitration Act and the Commercial Arbitration Rules of the American
Arbitration Association, except that discovery may be had in accordance with the
Federal Rules of Civil Procedure. The venue for the arbitration shall be the

an arbitrator and, within 10 business days after the end of such 15-day period,
such two arbitrators shall select a third arbitrator. Each arbitrator must
either have professional experience relating to the business or legal aspects of
the subject of the arbitration or be a retired judge. No arbitrator shall (i)
have any material interest in the result of the arbitration or (ii) be, or shall
ever have been, an affiliate, equity holder or creditor of, or an attorney,
accountant, agent or consultant for, any party to such arbitration proceeding.
The arbitrators shall meet promptly, fix the time, date and place of the hearing
and notify the parties. The parties shall stipulate that the arbitration hearing
shall last no longer than five business days. A majority of the panel shall
render a decision within 10 days of the completion of the hearing, which
decision may include an award of legal fees, costs of arbitration and interest.
The panel of arbitrators shall promptly transmit an executed copy of its
decision to the parties. The decision of the arbitrators shall be final, binding
and conclusive upon the parties. Each party shall have the right to have the
decision enforced by any court of competent jurisdiction. Notwithstanding any
other provision of this Section, any Dispute in which a party seeks equitable
relief may be brought in any court having jurisdiction. The obligations of the
parties under this Section shall be specifically enforceable and shall survive
any termination of this Agreement.

                  11. CONSULTANT'S ACKNOWLEDGMENTS. It is expressly understood
and agreed between the Company and the Consultant that the Consultant, in
entering into this Agreement and carrying out its obligations hereunder, is an
independent contractor, is not and shall not be deemed to be an agent or
employee of the Company, and shall have no power to bind the Company to any
contract or warranty or in any respect whatever, whether by written or oral
statements or by any course of dealing or in any other manner, without the
express written consent of the Company. Consultant agrees not to represent to
any person or corporation or other entity that the relationship of Consultant to
the Company is other than that of independent contractor.

                  12. MISCELLANEOUS. The invalidity or unenforceability of any
provision hereof shall in no way affect the validity or enforceability of any
other provision. This Agreement embodies the entire Agreement between the
parties hereto with respect to the subject matter hereof and supersedes any and
all prior or contemporaneous, oral or written understandings, negotiations, or
communications on behalf of such parties. This Agreement may be executed in any
number of counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument. The waiver by any
party of any breach or violation of any provision of this Agreement shall not
operate or be construed as a waiver of any subsequent breach or violation
hereof. This Agreement is executed in and shall be governed by and construed in
accordance with the laws of the State of Delaware. This Agreement may be amended
only by written agreement of all parties hereto. This Agreement shall be binding
on and inure to the benefit of the Company, the Consultant and their respective

Agreement and benefits accrued under this Agreement, Employee's employment and
all obligations of the Company under Article I hereof shall forthwith terminate;

compensation and provision of all benefits to Employee hereunder shall cease to
be effective as of the date of any such termination, except that Employee will

termination. The obligations of Employee under Article IV hereof shall continue
notwithstanding termination of Employee's employment pursuant to this Section
2.03(a).

                  (b) Without Cause. Employee's employment hereunder may be
terminated at any time by the Company without cause, provided that upon any such
termination without cause the Company shall pay Employee, subject to Employee's

Employee's employment pursuant to this Section 2.03(b).

         2.04 Employee Termination. Employee may terminate his employment
hereunder by giving the Company two months prior written notice of such
termination. Simultaneously with such notice, Employee shall inform the Company

under Article IV hereof shall continue notwithstanding termination of Employee's
employment pursuant to this Section 2.04.

contrary set forth in any stock option plan of the Company or any Stock Option
Agreement between the Company and Employee, in the event of termination of
Employee's employment hereunder for any reason other than for cause due to
Employee's willful misconduct or gross negligence, all stock options held by
Employee shall immediately vest and shall remain exercisable by Employee or
Employee's estate for a period of one year following such termination.

                                     FORM OF
                            NONCOMPETITION AGREEMENT


         This Agreement is made as of ____________ ___, 1999 between RUBICS
SOLUTIONS, INC., a Delaware corporation ("RUBICS"), and ____________________, an
individual residing in _________________ (the "SHAREHOLDER").

                                    PREAMBLE

         RUBICS (formerly, UBICS, Inc.) is party to separate Acquisition and
Stock Exchange Agreements (the "ACQUISITION AGREEMENTS") with R Systems, Inc.
("R SYSTEMS"), R Systems (India) Private Limited, an Indian corporation, and R
Systems (Singapore) Pte Limited, a Singapore company, each an affiliated company
of R Systems (together with R Systems, the "R SYSTEMS COMPANIES"), and their
respective shareholders, each dated as of even date herewith.

         The Shareholder owns shares of capital stock in one or more of the R
Systems Companies. To induce RUBICS to enter into the Acquisition Agreements,
the Selling Shareholder has agreed to refrain from competing with RUBICS, the R
Systems Companies and their Affiliates (as defined below) (collectively, the
"RUBICS GROUP"), upon the terms and conditions as set forth below.

         Therefore, in consideration of the mutual promises of the parties set
forth herein, and intending to be legally bound hereby, the parties agree as
follows:

                                    AGREEMENT

         1. Noncompetition and Nonsolicitation. During the period commencing on
the date hereof and ending on the earlier of the expiration of five years
following the date hereof or six months following a Change in Control (as
defined below) (the "TERM"), the Shareholder shall not, directly or indirectly,
as a partner, investor, stockholder, creditor, guarantor, advisor, officer,
director, employee or consultant, (i) own, manage, operate, join, advise,
control, or otherwise engage or participate in the business of providing
information technology services that are similar to or would be competitive with
the services provided by the RUBICS Group as currently being conducted on the
date hereof (the "BUSINESS") within the United States, India, Japan or
Singapore, (ii) induce or attempt to induce any customer or supplier of any
member of the RUBICS Group to reduce the business done by such supplier or
customer with the RUBICS Group, or (iii) solicit any employee of any member of
the RUBICS Group to leave the employ of the RUBICS Group other than family
members or relatives of the Shareholders. Notwithstanding the foregoing, this
Agreement does not prohibit the Shareholder from acquiring or holding the
outstanding shares of capital stock of any 


<PAGE>   153


entity engaged in the Business if such shares are publicly traded and the
Shareholder's ownership is less than four percent (4%) of such outstanding
shares. As used herein, an "AFFILIATE" of RUBICS or any R Systems Company means
any person or entity which controls, is controlled by or is under common control
with RUBICS or any R Systems Company.

                  (b) A "CHANGE IN CONTROL" is deemed to occur upon any of the
following events: (i) any individual, corporation, partnership, association,
trust or other entity becomes the beneficial owner (as defined in Rule 13(d)(3)
under the Securities Exchange Act of 1934), directly or indirectly, of
securities of RUBICS representing 50% or more of the combined voting power of
RUBICS's then outstanding voting securities; (ii) the individuals who as of the
date of this Agreement are members of the Board of Directors of RUBICS (the
"INCUMBENT BOARD"), cease for any reason to constitute at least a majority of
the Board of Directors of RUBICS (provided, however, that if the election, or
nomination for election by RUBICS's shareholders, of any new director was
approved by a vote of a least a majority of the Incumbent Board, such new
director will be considered to be a member of the Incumbent Board); (iii) an
agreement by RUBICS to consolidate or merge with any other entity pursuant to
which RUBICS will not be the continuing or surviving corporation or pursuant to
which shares of the Common Stock of RUBICS would be converted into cash,
securities or other property, other than a merger of RUBICS in which holders of
the Common Stock of RUBICS 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 RUBICS to sell, lease, exchange or
otherwise transfer in one transaction or a series of related transactions
substantially all the assets of RUBICS; (v) the adoption of any plan or proposal
for a complete or partial liquidation or dissolution of RUBICS; or (vi) an
agreement to sell more than 50% of the outstanding voting securities of RUBICS
in one or a series of related transactions other than an initial public offering
of voting securities registered with the Securities and Exchange Commission.

         2. Confidentiality.

                  (a) The Shareholder shall not, during the Term, without the
prior written consent of RUBICS, use for his own benefit or reveal to any third
party, any confidential, proprietary or trade secret information and material of
the RUBICS Group including, without limitation, technical details and know-how
relating to the services of the RUBICS Group, sales, sales volume, sales
methods, customers, customer purchases, marketing ideas (i.e. advertising and
selling techniques), suppliers, supplier information, and other confidential or
proprietary information belonging to the RUBICS Group or relating to the affairs
of the RUBICS Group (hereinafter collectively referred to as "PROPRIETARY
INFORMATION") (except to the extent required for performance by the Shareholder
of services for a member of the RUBICS Group under a service or similar
agreement). The Shareholder acknowledges that it is vital to the protection of
the 


                                      -2-
<PAGE>   154



RUBICS Group's goodwill and to the maintenance of the RUBICS Group's competitive
position that the Shareholder be restrained from disclosing to others, or using
for the Shareholder's own advantage, any Proprietary Information.

                  (b) Proprietary Information that is or was (i) already
publicly available or otherwise in the public domain prior, (ii) lawfully
obtained by the Shareholder from a source other than a member of the RUBICS
Group (or their officers, directors, employees, equity holders or agents) so
long as, in the case of information obtained from a third party, such third
party was not known to the Shareholder to be subject to an obligation of
confidentiality owed to a member of the RUBICS Group at the time such
Proprietary Information was or is disclosed to the Shareholder, or (iii) becomes
publicly available or otherwise comes into the public domain by means other than
a wrongful act of the Shareholder, shall not be considered Proprietary
Information for purposes of this Agreement.

         3. Injunctive Relief. The Shareholder acknowledges and agrees that the
covenants and agreements set forth in Sections 1 and 2 are necessary to protect
the legitimate business interests of RUBICS and that any breach of such
covenants and agreements will cause immediate and irreparable harm to RUBICS.
The Shareholder acknowledges that damages for the violation of any such covenant
or agreement will not give full and sufficient relief to RUBICS and agrees that,
in the event of any violation of any such covenant or agreement, RUBICS shall be
entitled to seek injunctive relief with respect to any such breach, which remedy
shall be in addition to any other remedy which RUBICS may have on account of
such breach, including, without limitation, the recovery of damages from the
Shareholder. None of these remedies shall be mutually exclusive, and all of them
may be pursued concurrently and cumulatively.

         4. Material Covenants. The Shareholder acknowledges that without his
covenants set forth in this Agreement, RUBICS would not be willing to consummate
the transactions contemplated by the Acquisition Agreements. The Shareholder
expressly agrees that the character, duration and geographical scope of this
Agreement are reasonable in light of the circumstances as they exist on the date
of this Agreement and are necessary to protect the legitimate business interests
of RUBICS because of the geographic scope of the RUBICS Group's business.

         5. Severability. It is the intent of the parties that each provision of
this Agreement be enforced to the fullest extent permissible under the laws and
public policies of each jurisdiction in which enforcement hereof is sought. In
furtherance of the foregoing, each provision hereof shall be severable from each
other provision. If any provision of this Agreement is adjudicated by a court of
competent jurisdiction to be invalid or unenforceable, the remainder of the
Agreement that can be given full force and effect without the invalid provision
shall continue in full force and effect and shall in no way be impaired or
invalidated.



                                      -3-

         6. Waivers and Amendments. No breach of any term of this Agreement
shall be deemed waived unless it is expressly waived in writing by the party who
might assert such breach. No waiver of any right hereunder shall operate as a
waiver of any other right or of the same or a similar right on another occasion.
To be effective, any amendment to this Agreement must be in writing and signed
by the party against whom enforcement of the same is sought.

         7. Entire Agreement. This Agreement, together with the Acquisition
Agreements, contains the entire understanding of the parties with regard to the
subject matter hereof, supersedes all prior agreements and understandings
relating to the subject matter hereof, and shall not be amended except by a
written instrument signed by all of the parties hereto.

         8. Governing Law. This Agreement shall be governed and construed in
accordance with the laws of the State of Delaware without giving effect to the
principles of conflicts of law thereof or of any other jurisdiction.

         9. Jurisdiction. Each of the parties hereto hereby expressly and
irrevocably submits to the non-exclusive personal jurisdiction of the United
States District Court for Delaware and to the jurisdiction of any other
competent court of the State of Delaware (collectively, the "DELAWARE COURTS"),
preserving, however, all rights of removal to such federal court under 28 U.S.C.
Section 1441, in connection with all disputes arising out of or in connection
with this Agreement and agrees not to commence any litigation relating thereto
except in such courts. If the aforementioned courts do not have subject matter
jurisdiction, then the proceeding shall be brought in any other state or federal
court located in the State of Delaware, preserving, however, all rights of
removal to such federal court under 28 U.S.C. Section 1441. Each party hereby
waives the right to any other jurisdiction or venue for any litigation arising
out of or in connection with this Agreement to which any of them may be entitled
by reason of its present or future domicile. Notwithstanding the foregoing, each
of the parties hereto agrees that each of the other parties shall have the right
to bring any action or proceeding for enforcement of a judgment entered by the
Delaware Courts in any other court or jurisdiction.

        10. Counterparts. This Agreement may be executed by the parties in
separate counterparts, each of which when so executed and delivered shall be an
original, but all such counterparts shall together constitute but one and the
same instrument.

        11. Successors and Assigns. This Agreement shall be binding upon and
shall inure to the benefit of each of the parties and their respective heirs,
personal representatives, successors and permitted assigns.

date hereof the Company elects, in its sole discretion, to register (including
for this purpose a registration effected by the Company for shareholders other

Company pursuant to a stock option, stock purchase or similar plan, or a
registration relating to a Rule 145 transaction or a registration on Form S-4 or

give each Holder written notice of such registration. Upon the written request
of each Holder given within thirty (30) days after mailing of such notice by the
Company, the Company shall, subject to the provisions of Sections 2.4, 2.6 and
2.7, use its best efforts to cause to be registered under the Securities Act all
of the Registrable Securities that each such Holder has requested to be

                           2.3 FORM S-3 REGISTRATION. Any Holder or group of
Holders holding at least $2,500,000 of Registrable Securities may, at any time
during the five-year period beginning on the date of this Agreement, demand that
the Company effect a registration on Form S-3 with respect to at most $2,500,000
of Registrable Securities. The Company shall be obligated to effect such
registration only once during each calendar year. Any such registration shall
also trigger the piggy-back registration rights of any Holder that does not
participate in the demand registration. The value of the Registrable Securities
for purposes of this Section 2.3 shall be determined by the 


                                       3
<PAGE>   160

closing price of the Company's Common Stock as reported by NASDAQ or any
securities exchange or market on which the Company's Common Stock is listed on
the date the demand for registration is received by the Company. Upon receipt of
a demand as set forth herein that the Company effect a registration on Form S-3
and any related qualification or compliance with respect to all or a part of the
Registrable Securities owned by such Holder or Holders, the Company will:

                                    (a) promptly give written notice of the
proposed registration, and any related qualification or compliance, to all other
Holders, and

                                    (b) as soon as practicable, effect such
registration and all such qualifications and compliances as may be so requested
and as would permit or facilitate the sale and distribution of all or such
portion of such Holder's or Holders' Registrable Securities as are specified in
such request, together with all or such portion of the Registrable Securities of
any other Holder or Holders joining in such request as are specified in a
written request given within fifteen (15) days after receipt of such written
notice from the Company; provided, however, that the Company shall not be
obligated to effect any such registration, qualification, or compliance pursuant
to this Section 2.3: (i) if the Company shall furnish to the holders a
certificate signed by the President of the Company stating that, in the good
faith judgment of the Board of Directors of the Company, it would be seriously
detrimental to the Company and its shareholders for such Form S-3 Registration
to be effected at such time, in which event the Company shall have the right to
defer the filing of the Form S-3 registration statement for a period of not more
than ninety (90) days after receipt of the request of the Holder or Holders
under this Section 2.3; or (ii) in any particular jurisdiction in which the
Company would be required to qualify to do business or to execute a general
consent to service of process in effecting such registration, qualification or
compliance.

                           2.4 OBLIGATIONS OF THE COMPANY. Whenever required
under this Section 2 to effect the registration of any Registrable Securities,
the Company shall, as expeditiously as reasonably possible:

                                    (a) Prepare and file with the SEC a
registration statement with respect to such Registrable Securities and use its
best efforts to cause such registration statement to become effective and keep
such registration statement effective until the earlier of (i) the date on which
all Registrable Securities covered by the registration statement are sold or
(ii) 180 days from the effective date of the registration statement.

                                    (b) Prepare and file with the SEC such
amendments and supplements to such registration statement and the prospectus
used in connection with such registration statement as may be necessary to
comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by such registration statement.


                                       4
<PAGE>   161


                                    (c) Furnish to the Holders such numbers of
copies of a prospectus, including a preliminary prospectus, in conformity with
the requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                                    (d) Use its best efforts to register and
qualify the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably
requested by the Holders, provided that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such states or jurisdiction.

                                    (e) In the event of any underwritten public
offering, enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the managing underwriter of such
offering. Each Holder participating in such underwriting shall also enter into
and perform its obligations under such an agreement.

                           2.5 FURNISH INFORMATION. It shall be a condition
precedent to the obligations of the Company to take any action pursuant to this
Section 2 that the selling Holders shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them, and the intended
method of disposition of such securities as shall be required to effect the
registration of their Registrable Securities.

                           2.6 EXPENSES OF REGISTRATION. All Registration
Expenses incurred in connection with any registration, filing, qualification or
compliance pursuant to Sections 2.2 or 2.3 shall be borne by the Company. Unless
otherwise stated, all Selling Expenses relating to securities registered by the
Holders shall be borne by the holders of such securities pro rata on the basis
of the number of shares so registered.

                           2.7 UNDERWRITING REQUIREMENTS. In connection with any
offering involving an underwriting of shares, the Company shall not be required
under Sections 2.2 or 2.3 to include any of the Holders' Registrable Securities
in such underwriting unless they accept the terms of the underwriting as agreed
upon between the Company and the underwriters selected by it, and then only in
such quantity as will not, in the opinion of the underwriters, jeopardize the
success of the offering by the Company or the Company's shareholders demanding
such registration. If the total amount of Registrable Securities that all
selling Holders of the Company request to be included in such offering exceeds
(when combined with the securities being offered by the Company or its
shareholders demanding such registration) the amount of securities that the
underwriters reasonably believe compatible with the success of the offering,
then the Company shall be required to include in the offering only that number
of such Registrable Securities which the underwriters believe will not
jeopardize the success of the offering (the securities so included to be
apportioned pro rata among the selling Holders according to the total amount of
Registrable Securities owned by each selling 



                                       5

Holder or in such other proportions as shall mutually be agreed to by such
selling Holders).

                           2.8 DELAY OF REGISTRATION. No Holder shall have any
right to obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 2. 

                           2.9 INDEMNIFICATION. In the event any Registrable
Securities are included in a registration statement under this Section 2:

                                    (a) To the extent permitted by law, the
Company will indemnify and hold harmless each Holder, the officers and directors
of each Holder, any underwriter (as defined in the Securities Act) for such
Holder and each person, if any who controls such Holder or underwriter within
the meaning of the Securities Act or Exchange Act, against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject
under the Securities Act, the Exchange Act or other federal or state law,
insofar as such losses, claims, damages, or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation"): (i) any untrue statement
or alleged untrue statement of a material fact contained in such registration
statement including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto; (ii) the omission or alleged
omission to state therein a material fact required to be stated therein, or
necessary to make the statements therein not misleading; or (iii) any violation
or alleged violation by the Company of the Securities Act, the Exchange Act, any
state securities law or any rule or regulation promulgated under the Securities
Act, the Exchange Act or any state securities law; and the Company will
reimburse each such Holder, officer or director, underwriter or controlling
person for any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such loss, claim, damage, liability, or
action, provided, however, that the indemnity agreement contained in this
Section 2.9(a) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability, or action if such settlement is effected without the
consent of the Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable in any such case for any such loss, claim, damage,
liability, or action to the extent that it arises out of or is based upon a
Violation which occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by
any such Holder, underwriter or controlling person.

                                    (b) To the extent permitted by law, each
selling Holder will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the registration statement, each
person, if any, who controls the Company within the meaning of the Securities
Act, any underwriter (within the meaning of the Securities Act) for the Company
or such other Holders, any person who controls such underwriter, and any other
Holder selling securities in such registration statement 



                                       6
<PAGE>   163


or any of its directors or officers or any person who controls such Holder,
against any losses, claims, damages, or liabilities (joint or several) to which
the Company or any such director, officer, controlling person, or underwriter or
controlling person, or other such Holder or director, officer or controlling
person may become subject, under the Securities Act, the Exchange Act or other
federal or state law insofar as such losses, claims, damages, or liabilities (or
actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished by such
Holder expressly for use in connection with such registration, and each such
Holder will reimburse any legal or other expenses reasonably incurred by the
Company or any such director, officer, controlling person, underwriter or
controlling person, other Holder, officer, director, or controlling person in
connection with investigating or defending any such loss, claim damage,
liability, or action, provided, however, that the indemnity agreement contained
in this Section 2.9(b) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Holder, which consent shall not be unreasonably withheld,
and, provided further that in no event shall any selling Holder's liability
hereunder exceed the gross proceeds actually received by such Holder in respect
of the sale of such Holder's shares in such offering.

                                    (c) Promptly after receipt by an indemnified
party under this Section 2.9 of notice of the commencement of any action
(including any governmental action), such indemnified party will, if a claim in
respect thereof is to be made against any indemnifying party under this Section
2.9, notify the indemnifying party in writing of the commencement thereof and
the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to notify an
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
2.9, but the omission so to notify the indemnifying party will not relieve it of
any liability that it may have to any indemnified party otherwise than under
this Section 2.9.

                           2.10 REPORTS UNDER EXCHANGE ACT. With a view to
making available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3, the Company agrees to:


                                       7
<PAGE>   164


                                    (a) make and keep public information
available as those terms are understood and defined in Rule 144, at all times
until all of the Registrable Securities are sold;

                                    (b) take such action as is necessary to
enable the Holders to utilize Form S-3 for the sale of their Registrable
Securities, and to continue to maintain Form S-3 eligibility. In the event that
the Company fails to be eligible to use Form S-3, the Company shall satisfy the
Holders' demand registration rights by using whatever form may be available to
effect such registration;

                                    (c) file with the SEC in a timely manner all
reports and other documents required of the Company under the Securities Act and
the Exchange Act; and

                                    (d) furnish to any Holder, so long as the
Holder owns any Registrable Securities, forthwith upon request: (i) a written
statement by the Company that it has complied with the reporting requirements of
Rule 144, the Securities Act and the Exchange Act, or that it qualifies as a
registrant whose securities may be resold pursuant to Form S-3 (at any time
after it so qualifies); (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company; and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

                                    (e) For so long as any Registrable
Securities remain unsold, use its best efforts to continue to list the Common
Stock on NASDAQ or a national securities exchange.

                           2.11 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to
cause the Company to register Registrable Securities pursuant to this Section 2
may be assigned by a Holder to a transferee or assignee of such Registrable
Securities, provided the Company is, within a reasonable time after such
transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned; and provided, further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Securities Act.

                           2.12 "MARKET STAND-OFF" AGREEMENT. Each Holder hereby
agrees that it shall not, to the extent requested by the Company and an
underwriter of Common Stock (or other securities) of the Company sell or
otherwise transfer or dispose of any Registrable Securities during the one
hundred and eighty (180) day period following the effective date of a
registration statement except for Registrable Securities which are included in
such registration statement of the Company filed under the Securities Act;
provided, however, that all officers and directors of the 



                                       8
<PAGE>   165


Company and all other persons with registration rights (whether or not pursuant
to this Agreement) enter into similar agreements.

                           In order to enforce the foregoing covenant, the
Company may impose stop-transfer instructions with respect to the Registrable
Securities of each Holder (and the shares or securities of every other person
subject to the foregoing restriction) until the end of such one hundred and
eighty (180) day period.

                           2.3 Termination of Registration Rights. The Company
shall not be obligated under this Section 2 to register or include in any
registration Registrable Securities held by any Holder from and after such time
as all Registrable Securities that such Holder holds may be publicly offered,
sold and distributed without registration under the Act pursuant to Rule 144.

                  3. MISCELLANEOUS.

                           3.1 This Agreement constitutes the entire agreement
between the Company and the Stockholders with respect to the subject matter
hereof. Any previous agreement between the Company and the Stockholders is
superseded by this Agreement. Subject to the exceptions specifically set forth
in this Agreement, the terms and conditions of this Agreement shall inure to the
benefit of and be binding upon the respective heirs, successors, administrators,
executors and assigns of the parties hereto.

                           3.2 Unless otherwise provided, any notice required or
permitted under this Agreement shall be given in writing and shall be deemed
effectively given upon personal delivery or facsimile to the party to be
notified or five (5) days after deposit with the United States Post Office, by
registered or certified mail, postage prepaid and addressed to the party to be

Financial Officer at the Company's principal executive office, and if to a
Holder, at the address indicated for such Holder on the signature pages hereto,
or at such other address as such party may designate by ten (10) days advance
written notice to the other parties.

                           3.3 This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

                           3.4 This Agreement shall be governed in all respects
by the laws of the State of Delaware applicable to contracts entered into and
wholly to be performed within the State of Delaware by Delaware residents. Any
disputes arising hereunder shall be subject to the dispute resolution provisions
set forth in the applicable Acquisition Agreement.

                            INDEMNIFICATION AGREEMENT


         This INDEMNIFICATION AGREEMENT is made as of ________________, 1999 by
and between RUBICS SOLUTIONS, Inc., a Delaware corporation (the "Corporation"),
and the undersigned director of the Corporation (the "Indemnitee").


                                   WITNESSETH:


         WHEREAS, Indemnitee is a member of the Corporation's Board of Directors
and in that capacity is performing a valuable service for the Corporation and
its stockholders and the Corporation desires to retain the continued service of
Indemnitee in that capacity; and

         WHEREAS, pursuant to Article VII of the Corporation's Amended and
Restated Certificate of Incorporation ("Certificate of Incorporation") and
Article III, Section 10 of the Corporation's Amended Bylaws ("Bylaws"),
Indemnitee is entitled to be indemnified by the Corporation to the full extent
permitted by law or a court, whichever is greater, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement incurred by
him in connection with any threatened, pending, or completed action, suit or
proceeding to which the Indemnitee was, is or is threatened to be made a party
by reason of the fact that he is or was a director, officer, incorporator,
employee, or agent of the Corporation, or is or was serving at the request of
the Corporation as a director, officer, incorporator, employee, or agent of
another corporation, partnership, joint venture, trust or other enterprise (the
"Indemnification Provisions"); and

         WHEREAS, consistent with the Indemnification Provisions of the
Corporation's Certificate of Incorporation and Bylaws, and as permitted by
Section 145(e) of the Delaware General Corporation Law, as amended ("DGCL"), and
in order to retain the continued service of the Indemnitee as a director of the
Corporation, the Corporation desires to agree to pay the expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by Indemnitee in defending any civil, criminal,
administrative or investigative action, suit or proceeding for which he may be
indemnified pursuant to the Indemnification Provisions in advance of the final
disposition of such action, suit or proceeding; and

         NOW, THEREFORE, in consideration of Indemnitee's continued service as a
director after the date of this Agreement, and intending to be legally bound,
the parties agree as follows:

         1. Maintenance of Insurance.

                  (a) Subject only to the provisions of Subsection 1(b) hereof,
so long as the Indemnitee shall continue to serve as a director, officer,
incorporator, employee or agent of the Corporation (or shall continue, at the
request of the Corporation, to serve 


<PAGE>   169

as a director, officer, incorporator, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise) and thereafter so long as
the Indemnitee shall be subject to any possible claim or threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative by reason of the fact that the Indemnitee was a director of the
Corporation or served in any of the above-described capacities, the Corporation
will purchase and maintain in effect for the benefit of the Indemnitee, one or
more valid, binding and enforceable policies of directors' and officers'
insurance ("D&O Insurance").

                  (b) The Corporation shall not be required to maintain D&O
Insurance in effect if such insurance is not reasonably available or if, in the
reasonable business judgment of the then directors of the Corporation, either
(i) the premium cost for such insurance is substantially disproportionate to the
amount of coverage or (ii) the coverage provided by such insurance is so limited
by exclusions that there is insufficient benefit from such insurance.

                  (c) In the event the Corporation does not purchase and
maintain in effect D&O Insurance pursuant to the provisions of Subsection 1(b)
hereof, the Corporation shall hold harmless and indemnify the Indemnitee to the
full extent of the coverage which would otherwise have been provided for the
benefit of the Indemnitee pursuant to such D&O Insurance.

         2. Indemnification.

                  Notwithstanding Subsection 1(a) hereof, the Corporation shall
indemnify the Indemnitee to the fullest extent permitted by law and the
Certificate of Incorporation, whichever is greater, in effect on the date hereof
or as such laws or the Certificate of Incorporation may from time to time be
amended. The right to indemnification conferred in the Certificate of
Incorporation and the Bylaws shall be presumed to have been relied on by
Indemnitee in serving or continuing to serve the Corporation (or if the
Indemnitee shall continue, at the request of the Corporation, to serve as a
director, officer, incorporator, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise) and shall be enforceable
as a contract right.

         3. Advancement of Expenses.

                  (a) The Corporation shall pay the expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred or estimated to be incurred by Indemnitee in connection with
any civil, criminal, administrative or investigative action, suit or proceeding
for which he would be entitled to be indemnified pursuant to the Indemnification
Provisions, the D&O Insurance, the DGCL or otherwise (in any capacity) in
advance of the final disposition thereof promptly after receipt by the
Corporation of a request therefor stating in reasonable 



                                      -2-
<PAGE>   170



detail the expenses incurred or to be incurred by him. No security shall be
required in connection with any advancement of expenses to Indemnitee hereunder
and such a request shall be accepted without reference to the Indemnitee's
ability to make a repayment.

                  (b) If a claim under Subsection 3(a) hereof is not paid in
full by the Corporation within thirty (30) days after a written claim has been
received by the Corporation, the Indemnitee may, at any time thereafter, bring
suit against the Corporation to recover the unpaid amount of the claim. The
burden of proving that advancement of expenses is not appropriate shall be on
the Corporation. The Corporation shall pay such fees and expenses in advance of
the final disposition of such action upon receipt of a written request therefor.

         4. Undertaking to Repay Expenses.

                  (a) In the event it shall ultimately be determined that the
Indemnitee is not entitled to be indemnified for the expenses paid by the
Corporation pursuant to the provisions of this Agreement or otherwise or was not
entitled to be fully indemnified, the Indemnitee shall repay to the Corporation
such amount of the expenses or the appropriate portion thereof, so paid or
advanced. This provision shall constitute the undertaking contemplated by
Section 145(e) of the DGCL and no further assurances shall be required of
Indemnitee before any expenses are advanced.

                  (b) Notwithstanding Subsection 4(a) hereof, the Corporation's
Board of Directors shall be deemed to have determined that the Indemnitee is
entitled to indemnification unless, within twenty (20) days after submission of
Indemnitee's request pursuant to Subsection 3(a) hereof, the Corporation's Board
of Directors shall have notified the Indemnitee in writing that it has
determined, by a majority vote of directors, based on clear and convincing
evidence, that the Indemnitee is not entitled to indemnification under this
Agreement. The evidence shall be disclosed to the Indemnitee in such notice
which shall be sworn to by all directors who participated in the determination
and voted to deny indemnification.

         5. Notice.

                  Any notice to the Corporation shall be directed to RUBICS,
Inc., 333 Technology Drive, Suite 210, Canonsburg, Pennsylvania 15317,
Attention: President (or such other address as the Corporation shall designate
in writing to the Indemnitee).

         6. Indemnification Under this Agreement Not Exclusive.

                  The rights provided to Indemnitee by this Agreement shall not
be exclusive of any other rights to which Indemnitee may be entitled under the



                                      -3-
<PAGE>   171

Corporation's Certificate of Incorporation, its Bylaws, any other agreement, any
vote of stockholders or directors, or otherwise, as to action in any capacity.

         7. Miscellaneous.

                  (a) This Agreement shall be interpreted and enforced in
accordance with the laws of the State of Delaware.

                  (b) This Agreement shall be binding upon Indemnitee and upon
