                 (FORMERLY AMENDED AND RESTATED 1994 STOCK PLAN)

         1. Purposes of the Plan. The purposes of this Stock Plan are to attract
and retain the best available personnel for positions of substantial
responsibility, to provide additional incentive to Employees, Directors and
Consultants and to promote the success of the Company's business. Options
granted under the Plan may be Incentive Stock Options or Nonstatutory Stock
Options, as determined by the Administrator at the time of grant. Stock Purchase
Rights may also be granted under the Plan.

sales were reported) as quoted on such exchange or system for the last market
trading day prior to the time of determination, as reported in The Wall Street
Journal or such other source as the Administrator deems reliable;

         (ii) If the Common Stock is regularly quoted by a recognized securities
dealer but selling prices are not reported, its Fair Market Value shall be the

market trading day prior to the day of determination; or

option and sold under the Plan is 1,500,000 Shares. The Shares may be authorized
but unissued, or reacquired Common Stock.

         If an Option or Stock Purchase Right expires or becomes unexercisable
without having been exercised in full, or is surrendered pursuant to an Option
Exchange Program, the unpurchased Shares which were subject thereto shall become
available for future grant or sale under the Plan (unless the Plan has
terminated). However, Shares that have actually been issued under the Plan, upon
exercise of either an Option or Stock Purchase Right, shall not be returned to
the Plan and shall not become available for future distribution under the Plan,
except that if Shares of Restricted Stock are repurchased by the Company at
their original purchase price, such Shares shall become available for future
grant under the Plan.
<PAGE>

         4. Administration of the Plan.

         (a) Administrator. The Plan shall be administered by the Board or a
Committee appointed by the Board, which Committee shall be constituted to comply
with Applicable Laws.

         (b) Powers of the Administrator. Subject to the provisions of the Plan
and, in the case of a Committee, the specific duties delegated by the Board to
such Committee, and subject to the approval of any relevant authorities, the
Administrator shall have the authority in its discretion:

         (i) to determine the Fair Market Value;

         (ii) to select the Service Providers to whom Options and Stock Purchase
Rights may from time to time be granted hereunder;

         (iii) to determine the number of Shares to be covered by each such
award granted hereunder;

         (iv) to approve forms of agreement for use under the Plan;

         (v) to determine the terms and conditions, of any Option or Stock
Purchase Right granted hereunder. Such terms and conditions include, but are not
limited to, the exercise price, the time or times when Options or Stock Purchase
Rights may be exercised (which may be based on performance criteria), any
vesting acceleration or waiver of forfeiture restrictions, and any restriction
or limitation regarding any Option or Stock Purchase Right or the Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

         (vi) to determine whether and under what circumstances an Option may be
settled in cash under subsection 9(e) instead of Common Stock;

         (vii) to reduce the exercise price of any Option to the then current
Fair Market Value if the Fair Market Value of the Common Stock covered by such
Option has declined since the date the Option was granted;

         (viii) to initiate an Option Exchange Program;

<PAGE>

         (ix) to prescribe, amend and rescind rules and regulations relating to
the Plan, including rules and regulations relating to sub-plans established for
the purpose of qualifying for preferred tax treatment under foreign tax laws;

         (x) to allow Optionees to satisfy withholding tax obligations by
electing to have the Company withhold from the Shares to be issued upon exercise
of an Option or Stock Purchase Right that number of Shares having a Fair Market
Value equal to the amount required to be withheld. The Fair Market Value of the
Shares to be withheld shall be determined on the date that the amount of tax to
be withheld is to be determined. All elections by Optionees to have Shares
withheld for this purpose shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable; and

         (xi) to construe and interpret the terms of the Plan and awards granted
pursuant to the Plan.

         (c) Effect of Administrator's Decision. All decisions, determinations
and interpretations of the Administrator shall be final and binding on all
Optionees.

         5.           Eligibility.

         (a) Nonstatutory Stock Options and Stock Purchase Rights may be granted
to Service Providers. Incentive Stock Options may be granted only to Employees.

         (b) Each Option shall be designated in the Option Agreement as either
an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $ 100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 5(b), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

         (c) Neither the Plan nor any Option or Stock Purchase Right shall
confer upon any Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall it interfere in
any way with his or her right or the Company's right to terminate such
relationship at any time, with or without cause.

         6. Term of Plan. The Plan shall become effective upon its adoption by
the Board. It shall continue in effect for a term of ten (10) years unless
sooner terminated under Section 14 of the Plan.

         7. Term of Option. The term of each Option shall be stated in the
Option Agreement; provided, however, that the term shall be no more than ten
(10) years from the date of grant thereof.

its determination as to the type of consideration to accept, the Administrator
shall consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

         9. Exercise of Option.

         (a) Procedure for Exercise, Rights as a Shareholder. Any Option granted
hereunder shall be exercisable according to the terms hereof at such times and
under such conditions as determined by the Administrator and set forth in the
Option Agreement. Except in the case of Options granted to Officers, Directors
and Consultants, Options shall become exercisable at a rate of no less than 20%
per year over five (5) years from the date the Options are granted. Unless the
Administrator provides otherwise, vesting of Options granted hereunder shall be
tolled during any unpaid leave of absence. An Option may not be exercised for a
fraction of a Share.

         An Option shall be deemed exercised when the Company receives: (i)
written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Shares, notwithstanding the exercise of the Option. The
Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

         Exercise of an Option in any manner shall result in a decrease in the
number of Shares thereafter available, both for purposes of the Plan and for
sale under the Option, by the number of Shares as to which the Option is
exercised.

         (b) Termination of Relationship as a Service Provider. If an Optionee
ceases to be a Service Provider, such Optionee may exercise his or her Option
within such period of time as is specified in the Option Agreement (of at least
thirty (30) days) to the extent that the Option is vested on the date of
termination (but in no event later than the expiration of the term of the Option
as set forth in the Option Agreement). In the absence of a specified time in the
Option Agreement, the Option shall remain exercisable for three (3) months
following the Optionee's termination. If, on the date of termination, the
Optionee is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option shall revert to the Plan. If, after termination,
the Optionee does not exercise his or her Option within the time specified by
the Administrator, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.
<PAGE>

         (c) Disability of Optionee. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
(of at least six (6) months) to the extent the Option is vested on the date of
termination (but in no event later than the expiration of the term of such
Option as set forth in the Option Agreement). In the absence of a specified time
in the Option Agreement, the Option shall remain exercisable for twelve (12)
months following the Optionee's termination. If, on the date of termination, the
Optionee is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option shall revert to the Plan. If, after termination,
the Optionee does not exercise his or her Option within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

         (d) Death of Optionee. If an Optionee dies while a Service Provider,
the Option may be exercised within such period of time as is specified in the
Option Agreement (of at least six (6) months) to the extent that the Option is
vested on the date of death (but in no event later than the expiration of the
terms of such Option as set forth in the Option Agreement) by the Optionee's
estate or by a person who acquires the right to exercise the Option by bequest
or inheritance. In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to the
entire Option, the Shares covered by the unvested portion of the Option shall
immediately revert to the Plan. If the Option is not so exercised within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

         (e) Buyout Provisions. The Administrator may at any time offer to buy
out for a payment in cash or Shares, an Option previously granted, based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.

         10. Non-Transferability of Options and Stock Purchase Rights. The
Options and Stock Purchase Rights may not be sold, pledged, assigned,
hypothecated, transferred, or disposed of in any manner other than by will or by
the laws of descent or distribution and may be exercised, during the lifetime of
the Optionee, only by the Optionee.
<PAGE>

         11. Stock Purchase Rights.

         (a) Rights to Purchase. Stock Purchase Rights may be issued either
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically of the terms, conditions and restrictions
related to the offer, including the number of Shares that such person shall be
entitled to purchase, the price to be paid, and the time within which such
person must accept such offer. The terms of the offer shall comply in all
respects with Section 260.140.42 of Title 10 of the California Code of
Regulations. The offer shall be accepted by execution of a Restricted Stock
purchase agreement in the form determined by the Administrator.

         (b) Repurchase Option. Unless the Administrator determines otherwise,
the Restricted Stock purchase agreement shall grant the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's service with the Company for any reason (including death or
disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock purchase agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at such rate as the
Administrator may determine. Except with respect to Shares purchased by
Officers, Directors and Consultants, the repurchase option shall in no case
lapse at a rate of less than 20% per year over five (5) years from the date of
purchase.

         (c) Other Provisions. The Restricted Stock purchase agreement shall
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.

         (d) Rights as a Shareholder. Once the Stock Purchase Right is
exercised, the purchaser shall have rights equivalent to those of a shareholder
and shall be a shareholder when his or her purchase is entered upon the records
of the duly authorized transfer agent of the Company. No adjustment shall be
made for a dividend or other right for which the record date is prior to the
date the Stock Purchase Right is exercised, except as provided in Section 12 of
the Plan.

         12. Adjustments Upon Changes in Capitalization. Merger or Asset Sale.

         (a) Changes in Capitalization. Subject to any required action by the
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company. The conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option or Stock Purchase Right.
<PAGE>

         (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option or Stock Purchase Right until
fifteen (15) days prior to such transaction as to all of the Optioned Stock
covered thereby, including Shares as to which the Option or Stock Purchase Right
would not otherwise be exercisable. In addition, the Administrator may provide
that any Company repurchase option applicable to any Shares purchased upon
exercise of an Option or Stock Purchase Right shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised, an
Option or Stock Purchase Right will terminate immediately prior to the
consummation of such proposed action.

         (c) Merger or Asset Sale. In the event of a merger of the Company with
or into another corporation, or the sale of substantially all of the assets of
the Company, each outstanding Option and Stock Purchase Right shall be assumed
or an equivalent option or right substituted by the successor corporation or a
Parent or Subsidiary of the successor corporation. In the event that the
successor corporation refuses to assume or substitute for the Option or Stock
Purchase Right, the Optionee shall fully vest in and have the right to exercise
the Option or Stock Purchase Right as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or excercisable. If an
0ption or Stock Purchase Right becomes fully vested and exercisable in lieu of
assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify the Optionee in writing or electronically that the
Option or Stock Purchase Right shall be fully exercisable for a period of
fifteen (15) days from the date of such notice, and the Option or Stock Purchase
Right shall terminate upon the expiration of such period. For the purposes of
this paragraph, the Option or Stock Purchase Right shall be considered assumed
if, following the merger or sale of assets, the option or right confers the
right to purchase or receive, for each Share of Optioned Stock subject to the
Option or Stock Purchase Right immediately prior to the merger or sale of
assets, the consideration (whether stock, cash, or other securities or property)
received in the merger or sale of assets by holders of Common Stock for each
Share held on the effective date of the transaction (and if holders were offered
a choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares); provided, however, that if such
consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option or Stock Purchase Right, for each Share
of Optioned Stock subject to the Option or Stock Purchase Right, to be solely
common stock of the successor corporation or its Parent equal in fair market
value to the per share consideration received by holders of Common Stock in the
merger or sale of assets.

         13. Time of Granting Options and Stock Purchase Rights. The date of
grant of an Option or Stock Purchase Right shall, for all purposes, be the date
on which the Administrator makes the determination granting such Option or Stock
Purchase Right, or such other date as is determined by the Administrator. Notice
of the determination shall be given to each Service Provider to whom an Option
or Stock Purchase Right is so granted within a reasonable time after the date of
such grant.

<PAGE>

         14. Amendment and Termination of the Plan.

         (a) Amendment and Termination. The Board may at any time amend, alter,
suspend or terminate the Plan.

         (b) Shareholder Approval. The Board shall obtain shareholder approval
of any Plan amendment to the extent necessary and desirable to comply with
Applicable Laws.

         (c) Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

         15. Conditions Upon Issuance of Shares.

         (a) Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

         (b) Investment Representations. As a condition to the exercise of an
Option, the Administrator may require the person exercising such Option to
represent and warrant at the time of any such exercise that the Shares are being
purchased only for investment and without any present intention to sell or
distribute such Shares if, in the opinion of counsel for the Company, such a
representation is required.

         16. Inability to Obtain Authority. The inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

         17. Reservation of Shares. The Company, during the term of this Plan,
shall at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

         18. Shareholder Approval. The Plan shall be subject to approval by the
shareholders of the Company within twelve (12) months after the date the Plan is
adopted. Such shareholder approval shall be obtained in the degree and manner
required under Applicable Laws.<PAGE>

whole number of shares of USI Common Stock, and (ii) the per share exercise
price for the shares of USI Common Stock issuable upon exercise of such assumed
option will be equal to the quotient determined by dividing the exercise price
per share of Soft Plus Common Stock at which such Soft Plus Option was
exercisable immediately prior to the Effective Time by the Optionholder Exchange
Ratio, rounded up to the nearest whole cent. Each Soft Plus Optionholder shall
be vested in the option to purchase USI Common Stock in the same proportion that
such Soft Plus Optionholder was vested in his or her Soft Plus Option as of the
Closing Date, and shall continue to vest in the option to purchase USI Common
Stock in accordance with the same vesting schedule applicable to such Soft Plus
Optionholder's Soft Plus Option prior to the Closing Date with respect to
service performed for USI following the Closing Date. It is the intention of the
parties that the Soft Plus Options assumed by USI qualify following the
Effective Time as incentive stock options as defined in section 422 of the Code
if, and only to the extent, such Soft Plus Options qualified as incentive stock
options prior to the Effective Time.

               3.1.3.5 On and after the Closing Date, each Soft Plus
Optionholder holding a Soft Plus Option shall cease to have any rights as an
Optionholder of Soft Plus, except for his, her or its rights as a holder of Soft
Plus Options to purchase USI Common Stock pursuant to the terms of the Soft Plus
Option Plans and applicable grant letters, and no transfer of Soft Plus Options
shall be made on the transfer books of Acquisition. Following the Closing, USI
will provide written notice to each person who immediately prior to the
Effective Time was a Soft Plus Optionholder of USI's assumption of such Soft
Plus Option.

               3.1.3.6 All outstanding warrants to purchase Soft Plus Common
Stock shall terminate unexercised by virtue of the Merger and without any action
on the part of the holder thereof.

         3.1.4 Adjustment of the principal amount of the USI Note. At the
Closing or in connection with the Post-Closing Audit (as defined in Section
9.5), the principal amount of the USI Note shall be adjusted as provided in this
Section 3.1.4. If the principal amount of the USI Note is not outstanding at the
time such adjustment is to be made under this Section 3.1.4, then USI shall be
entitled to receive Escrow Shares with a value (based on the USI Closing Date
Price) equal to the adjustment required by this Section 3.1.4. If the
Post-Closing Audit requires an adjustment that has an effect on more than one of
the following subsections, then USI shall have the right to select only one of
the subsections so effected for purposes of the adjustment required under this
Section 3.1.4. Any adjustment hereunder shall considered a reduction of the
original consideration paid by USI hereunder.

               3.1.4.1 The principal amount of the USI Note shall be reduced by
the amount the Soft Plus Debt as of the Closing Date exceeds the Soft Plus Debt

                                       8
<PAGE>

Ceiling, as determined in connection with the Post-Closing Audit if any Soft
Plus Debt from and after the date hereof is incurred other than in accordance
with Section 8.1.1.6.

               3.1.4.2 The principal amount of the USI Note shall be reduced by
the amount the Post-Closing Audit determines Soft Plus's shareholders' equity is
less than $2.2 million (Soft Plus's shareholders' equity as reported on its
financial statements as at December 31, 1999), before taking into account
deferred stock compensation charges.

               3.1.4.3 The principal amount of the USI Note shall be reduced by
the product of (a) the amount the Post-Closing Audit determines Soft Plus's
gross revenue for 1999 is less than $24 million (Soft Plus's projected gross
revenue based on its financial statements for the period ended December 31,
1999), multiplied by (b) the dollar amount resulting from dividing the Merger
Value by $24 million.

               3.1.4.4 The principal amount of the USI Note shall be reduced by
the Professional Fees paid by USI in accordance with Section 8.5 in excess of
the Expense Threshold.

               3.1.4.5 The principal amount of the USI Note shall be reduced by
the aggregate cost to acquire all right, title and interest of the minority
shareholders in Soft Plus Systems Private Limited (India), including all legal
fees and related regulatory costs and expenses in excess of $10,000.

         3.1.5 Escrow Shares. USI Common Stock equal to ten percent (10%) of the
Merger Value (that number of shares equal to ten percent of the quotient of (a)
the Merger Value divided by (b) the USI Closing Date Price, herein the "Escrow
Shares") will be issued to the Escrow Agent to hold, subject to the following
sentence, for a period of one year following the Closing Date as escrow agent in
accordance with an escrow agreement, by and among USI, the Soft Plus Shareholder
Agent on behalf of all Soft Plus Shareholders and the Escrow Agent to be
executed and delivered at the Closing in the form attached hereto as Exhibit H
(the "Escrow Agreement") for purposes of the indemnification provided in Article
XII. The cost and expense of such escrow and the Escrow Agent shall be borne
equally by USI and the Principal Shareholders. If USI pays the full cost of such
fees and expenses, it may set-off against the principal amount of the USI Note,
or make a claim against the Escrow Fund, as USI may elect, the share of such
fees and expenses of the Principal Shareholders.

         3.1.6 Anti-Dilution Provisions. If USI changes (or establishes a record
date for changing) the number of shares of USI Common Stock issued and
outstanding prior to the Closing Date as a result of a stock split, stock
dividend, recapitalization, subdivision, reclassification, combination, exchange
of shares or similar transaction with respect to the outstanding USI Common
Stock and the record date therefor shall be prior to the Closing Date, the
Shareholder Exchange Ratio and the Optionholder Exchange Ratio shall be
proportionately adjusted to reflect fully such split, stock dividend,
recapitalization, subdivision, reclassification, combination, exchange of shares
or similar transaction.

     3.2 Exchange of Certificates.

         3.2.1 Surrender of Certificates and Disbursement. Subject to the terms
hereof and upon the surrender of the Certificates to USI (or to an agent for
such purpose designated by USI) by each Soft Plus Shareholder together with a
Letter of Transmittal substantially in the form of Exhibit I (the "Letter of
Transmittal") and any necessary stock powers and other documents (including
forms W-9 and W-8, as required by USI or Acquisition), duly executed and, if
required, with signatures notarized or guaranteed, each holder of such
Certificates shall be entitled to receive in exchange therefor USI Common Stock,
a pro rata portion of Closing Cash Consideration, and a pro rata portion of the
cash proceeds of the USI Note once the USI Note is paid in full in accordance
with its terms as provided herein and therein. Upon such surrender, USI or its
designee will promptly tender or cause to be tendered the USI Common Stock and
the pro rata portion of Closing Cash Consideration to each such holder. If USI
engages a third party to act as the paying agent hereunder, the fees and
expenses thereof shall be borne one-half by USI and one-half by the Principal
Shareholders. If USI pays the full cost of such fees and expenses, it may
set-off against the principal amount of the USI Note, or make a claim against
the Escrow Fund, as USI may elect, the share of such fees and expenses of the
Principal Shareholders.

         3.2.2 Transferred Certificates. If USI Common Stock and Closing Cash
Consideration is to be delivered to a Person other than the Person in whose name
the Certificates surrendered in exchange therefor are registered, it shall be a
condition to the delivery of the USI Common Stock and the cash portion of the
Cash Consideration at the Closing that the Certificates so surrendered shall be
properly endorsed or accompanied by appropriate stock transfer powers and any
other documents required by USI and otherwise in proper form for transfer, that
such transfer otherwise be proper and that the Person requesting such transfer
pay to the Soft Plus Shareholder Agent any transfer or other taxes payable by
reason of the foregoing or establish to the satisfaction of USI or its designee
that such taxes have been paid or are not required to be paid.

         3.2.3 Delivery of USI Common Stock. At the Closing USI or its designee
shall deliver to each Soft Plus Shareholder who has complied with the delivery
requirements of Section 3.2.1 above such Soft Plus Shareholder's pro rata share
of the Closing Cash Consideration, and as promptly as reasonably and
commercially possible following the Closing USI shall deliver or cause to be
delivered by USI or its designee a certificate in the name of each Soft Plus
Shareholder representing that number of whole shares of USI Common Stock, in
each case as such Soft Plus Shareholder is entitled; provided, however, USI
shall retain the per share Closing Cash Consideration with respect to any
Unvested Soft Plus Shares, which USI shall hold, together with in accordance
with Section 3.2.8. If USI delivers shares of USI Common Stock and the Closing
Cash Consideration with its designee, or upon delivery of the same to each such
Soft Plus Shareholder, none of USI, Acquisition or the Soft Plus shall have any
further liability to the Soft Plus Shareholders with respect to the USI Common
Stock to be delivered at the Closing.

         3.2.4 Delivery of the USI Note. At the Closing, USI shall deliver to
the Soft Plus Shareholder Agent the USI Note to be held by the Soft Plus
Shareholder Agent in accordance with the Soft Plus Shareholder Agent Agreement
until the USI Note is paid in full in accordance with its terms. Each Soft Plus
Shareholder shall be entitled to receive a pro rata portion of the proceeds of
the USI Note when paid in full, based on the relative number of shares of USI
Common Stock received at or in connection with the Closing by Soft Plus
Shareholders, as the same may be reduced to reflect shares of USI Common Stock
into which Unvested Soft Plus Shares are converted and exchanged in connection
with the Merger that are repurchased in accordance with the provisions of
Section 3.2.8.

                                       10
<PAGE>

         3.2.5 Delivery of USI Common Stock to the Escrow Agent. At the Closing,
USI shall deliver certificates representing the Escrow Shares to the Escrow
Agent for holding pursuant to the terms of the Escrow Agreement.

         3.2.6 Delivery of Soft Plus Common Stock. In order for a Soft Plus
Shareholder to receive the Merger Consideration to which such Soft Plus
Shareholder is entitled, such Soft Plus Shareholder shall comply with the
delivery requirements of Section 3.2.1 above. Each such Certificate or an
attached stock power shall be duly and validly endorsed in the name of
Acquisition and in proper form for transfer.

         3.2.7 No Fractional Shares. As permitted by Section 407 of the CGCL,
fractional shares shall be disregarded for all Soft Plus Shareholders who, if
fractional shares were to be issued in connection with the Merger, would
otherwise have received a fraction of a share of USI Common Stock that
represents less than one-half of one percent (.5%) of the total shares of USI
Common Stock any Soft Plus Shareholder is entitled to receive in connection with
the Merger. No certificates or scrip representing fractional shares of USI
Common Stock shall be issued upon the surrender for exchange of Certificates, no
dividend or distribution of USI shall relate to such fractional share interests
and such fractional share interests will not entitle the owner thereof to vote
or to any rights of a stockholder of USI.

         3.2.8 Certain Restrictions.

               3.2.8.1 Certain shares of Soft Plus Common Stock were issued
under and subject to certain Restricted Stock Purchase Agreements. Such shares
of Soft Plus Common Stock that remain unvested immediately following the Closing
are referred to herein as the Unvested Soft Plus Shares. The shares of USI
Common Stock into which Unvested Soft Plus Shares are exchanged in accordance
with the terms hereof shall continue to be subject to the terms and conditions
of such Restricted Stock Purchase Agreements, and a legend regarding such terms
and conditions shall be set forth on such Certificates, in addition to any other
applicable legend thereon.

               3.2.8.2 Each of the Soft Plus Shareholders listed on Schedule
3.2.8.2 will hold the number of Unvested Soft Plus Shares set forth such
Schedule as of the Closing Date. Shares of USI Common Stock into which such
Unvested Soft Plus Shares are converted and exchanged in connection with the
Merger shall remain unvested and shall remain subject to a right of repurchase
by USI, as provided in the foregoing subsection. Until the time such shares
become fully vested and are no longer subject to repurchase by USI, USI shall
hold and retain such shares and the per share Closing Cash Consideration to
which a holder of a Unvested Soft Plus Shares would otherwise be entitled in
connection with the Merger. USI shall release such shares and the applicable
Closing Cash Consideration as promptly as commercially reasonable following the
date such shares become fully vested and are no longer subject to a right of
repurchase.

               3.2.8.3 Shares of USI Common Stock that are not exchanged in
accordance with the terms hereof, if any, and only to the extent permitted by
law, including the provisions of applicable escheat laws, shall not be issued by
USI to a former Soft Plus Shareholder, but shall be retained to satisfy claims,
if any, arising from or relating to any verbal offer, commitment, understanding

                                       11

or agreement to issue any equity interest in Soft Plus to any Person. Any shares
not so exchanged shall be returned to the treasury of USI.

         3.2.9 Dissenting Shares.

               3.2.9.1 Each outstanding share of Soft Plus Common Stock or Soft
Plus Preferred Stock held by a Soft Plus Shareholder who has demanded and
perfected his or her right to an appraisal of his or her shares in accordance
with section 1301 of the CGCL and who has not effectively withdrawn or lost such
right to such appraisal ("Dissenting Shares") shall not be converted into or
represent a right to receive USI Common Stock or a pro rata share of the Cash
Consideration based upon the Shareholder Exchange Ratio (as the same may be
adjusted in accordance with the terms hereof) pursuant to Section 3.1.3 and the
other provisions of this Article III, but the holder thereof shall be entitled
only to such rights as are granted by Chapter 13 of the CGCL. Each holder of
Dissenting Shares who becomes entitled to payment for Soft Plus Common Stock or
Soft Plus Preferred Stock then owned pursuant to Chapter 13 of the CGCL shall
receive payment therefor from USI in accordance with the CGCL.

               3.2.9.2 If any Soft Plus Shareholder who demands appraisal of
his, her or its shares under Chapter 13 of the CGCL shall effectively withdraw
or lose (through failure to perfect or otherwise) his, her or its right to
appraisal, each share of Soft Plus Common Stock and/or Soft Plus Preferred Stock
held by such Soft Plus Shareholder, and each shall automatically be converted
into the right to receive that number of shares of USI Common Stock equal to the
Shareholder Exchange Ratio, rounded down to the nearest whole number, plus a
portion of the Cash Consideration equal to the product of (a) the Cash
Consideration Ratio multiplied by (b) the Cash Consideration, and all such
shares of Soft Plus Common Stock and Soft Plus Preferred Stock shall be
delivered in accordance with the provisions of this Article III.

               3.2.9.3 Prior to the Closing, Soft Plus shall give USI and
Acquisition prompt notice of any written demands for appraisal, withdrawals of
demands for appraisal and any other instruments served pursuant to Chapter 13 of
the CGCL received by Soft Plus. From and after the Closing USI shall give the
Soft Plus Shareholder Agent prompt notice of any written demands for appraisal,
withdrawals of demands for appraisal and any other instruments served pursuant
to Chapter 13 of the CGCL received by Acquisition.

         3.2.10 Lost Certificates. If any Certificate shall have been lost,
stolen or destroyed, upon the delivery to USI or its designee of a notarized
affidavit of that fact by the Person claiming such Certificate to be lost,
stolen or destroyed, USI or its designee will cause to be issued the allocable
USI Common Stock and Cash Consideration to such Person; provided, however, that
as a condition to such issuance USI or its designee may, in its discretion,
require the owner of such lost or destroyed Certificate to give USI or its
designee a bond in such sum as USI or its designee may reasonably direct as
indemnity against any claim that may be made with respect to the Certificate
alleged to have been lost, stolen or destroyed.

         3.2.11 Legends. Each stock certificate evidencing the USI Common Stock,
whether delivered at the Closing or to the Escrow Agent, shall be designated
with such legend or legends as shall be deemed necessary or appropriate by USI
upon the advice of its counsel.

exceptions as are specifically disclosed in the Schedules referred to in the
following Section, dated as of the date of this Agreement and delivered by the
Principal Shareholders to USI and Acquisition prior to the execution and

that specifically references a Section or subsection of this Agreement shall be
deemed to qualify only the representation, warranty, covenant, statement or
certificate delivered in connection herewith to which it specifically relates
unless specifically incorporated in and cross-referenced in another Schedule.

     5.1 Organization; Qualification.

     Each of Soft Plus and its Subsidiaries is a corporation or other legal
entity duly organized, validly existing and in good standing (with respect to
jurisdictions which recognize such concept) under the laws of the jurisdiction
in which it is organized and has the requisite corporate or other power, as the
case may be, and authority to carry on its business as now being conducted,
except for those jurisdictions where the failure to be so organized, existing or
in good standing individually or in the aggregate is not reasonably likely to
have a material adverse effect on Soft Plus or any of its Subsidiaries. Each of
Soft Plus and its Subsidiaries is duly qualified or licensed to do business and
is in good standing (with respect to jurisdictions which recognize such concept)
in each jurisdiction in which the nature of its business or the ownership,
leasing, licensing or operation of its properties makes such qualification or
licensing necessary, except for those jurisdictions where the failure to be so
qualified or licensed or to be in good standing individually or in the aggregate
is not reasonably likely to have a material adverse effect on Soft Plus. Copies
of the articles of incorporation and bylaws of Soft Plus heretofore delivered to
USI are accurate and complete as of the date hereof and as of the Closing Date.

     5.2 Subsidiaries.

     Schedule 5.2 sets forth a true, correct and complete list of (a) the name
and jurisdiction of incorporation of each Subsidiary of Soft Plus in which Soft
Plus owns, directly or indirectly, capital stock, (b) the total number of shares
of each class of capital stock of each Subsidiary authorized, the number of such
shares outstanding and the number of such shares owned by Soft Plus or any of
the Subsidiaries (indicating the name of the owner), and (c) a true, correct and
complete list of the directors and officers of Soft Plus and each Subsidiary.
All of the issued and outstanding shares of each Subsidiary have been duly and
validly authorized and issued and are fully paid, nonassessable and free of
preemptive rights. No shares of any Subsidiary have been issued in violation of
the preemptive rights of any shareholder of such Subsidiary. The shares of each
Subsidiary were issued in compliance with all applicable federal, state and
foreign securities laws and regulations, and are owned as set forth in Schedule
5.2, free and clear of any and all Liens and free of any restriction on the
right to vote, sell or otherwise dispose of such capital stock or other
ownership interests. Except for Soft Plus's ownership of the Subsidiaries as
disclosed on Schedule 5.2 and as may be otherwise described in such Schedule,
Soft Plus does not, directly or indirectly, have any ownership or other interest
in, or control of, any Person, nor is Soft Plus an affiliate of any Person other
than the shareholders of Soft Plus set forth on Schedule 3.2.3. The interests in
Soft Plus Systems Private Limited (India) not otherwise owned by Soft Plus (the
"Indian Subsidiary Minority Interest") are subject to repurchase on and after
May 1, 2000 (the "India Repurchase"), Soft Plus has executed a memorandum of
understanding in the form of Exhibit I-1 ("MOU") which assuming due
authorization, execution and delivery by the other parties thereto, creates a
valid and binding agreement, enforceable in accordance with its term, for Soft
Plus to acquire the Indian Subsidiary Minority Interest in accordance with
applicable law and without interfering with the on-going operations of Soft Plus
Systems Private Limited (India). Soft Plus is the equitable owner of 89.96%
interest in Soft Plus Systems Private Limited (India), has applied for the
necessary and appropriate authorization for the issuance to Soft Plus of such
equity interest in Soft Plus Systems Private Limited (India), and to the
knowledge of the Principal Shareholders there is no reason why such
authorization will not be granted.

grant attached hereto as Exhibit G with no material variation in the terms
thereof.

         5.3.7 Except as specifically described in this Section 5.3 or set forth
in Schedule 5.3.7, (x) there are not issued, reserved for issuance or

         5.3.8 Each Soft Plus Shareholder who acquired shares of Soft Plus
Common Stock under a restricted stock purchase agreement filed an election under
section 83(b) of the Code, and Soft Plus has received a copy of each such
election.

     5.4 Authority; Noncontravention.

         5.4.1 Soft Plus has all requisite corporate power and authority to
enter into this Agreement and to consummate the transactions contemplated by
this Agreement. The execution and delivery of this Agreement by Soft Plus and
the consummation by Soft Plus of the transactions contemplated by this Agreement
has been duly authorized by all necessary corporate action on the part of Soft
Plus, subject only to providing notice to Soft Plus Shareholders as provided in

and, assuming due authorization, execution and delivery by USI and Acquisition,
constitutes legal, valid and binding obligations of Soft Plus, enforceable
against Soft Plus in accordance with its terms.

         5.4.2 Without limiting the other provisions of Section 5.4.1 above, the
Board of Directors of Soft Plus, at a meeting duly called and held has, in light
of and subject to the terms and conditions set forth herein, determined that
this Agreement, the Merger and the other transactions contemplated hereby are
fair and in the best interests of the Soft Plus Shareholders.

         5.4.3 Except as set forth on Schedule 5.4.3, the execution and delivery

rights or benefits that each Principal Shareholder may have pursuant to Article
XII below.

         The foregoing shall not be a waiver of any claim to payments due to and
accrued on the books and records of Soft Plus prior to the Effective Date, nor
shall it act as a wavier of any right to indemnification for a claim made or
asserted by or on behalf of a Person not a party hereto, or an employee or
affiliate of Soft Plus, whether such indemnification arises by way of insurance,
under Soft Plus's bylaws or contact if consistent with the articles of
incorporation of Soft Plus and the applicable provisions of the CGCL.

         Notwithstanding the immediately preceding sentence, the foregoing is
specifically intended to waive any rights to severance or other payments that
are or may be due as a result of the termination of the employment agreement of
each Principal Shareholder with Soft Plus in connection with the Merger, it
being acknowledged and agreed that the employment with Soft Plus shall not end
as a result of said termination.

business or the ownership, leasing or operation of its properties makes such
qualification or licensing necessary, except for those jurisdictions where the

in the aggregate is not reasonably likely to have a material adverse effect on
USI. USI has made available to Soft Plus prior to the execution of this
Agreement true, correct and complete of its certificate of incorporation and
bylaws and the certificate of incorporation and bylaws of USI and Acquisition,
in each case as amended to date.

with the SEC by USI prior to the date hereof, and USI will have made available
to Soft Plus true and complete copies of any additional documents filed with the
SEC by USI after the date hereof and prior to the Closing Date (collectively,

Documents complied in all material respects with the requirements of the
Exchange Act and the Securities Act

included in the USI SEC Documents (the "USI Financial Statements") were complete
and correct in all material respects as of their respective filing dates,
complied as to form in all material respects with applicable accounting

respect thereto as of their respective dates, and have been prepared in
accordance with GAAP applied on a basis consistent throughout the periods
indicated and consistent with each other (except as may be indicated in the
notes thereto or, in the case of unaudited statements, included in Quarterly

consolidated financial condition and operating results of USI and its
subsidiaries at the dates and during the periods indicated therein (subject, in
the case of unaudited statements, to normal, recurring year-end adjustments).
There has been no change in USI accounting policies except as described in the
notes to the USI Financial Statements. Since the date of the most recently filed
USI SEC Document, USI's Quarterly Report on Forms 10-Q, there has been no
material adverse change in USI's business or the results of its operations.

         7.7.3 USI agrees to use its reasonable best efforts to file with the
SEC in a timely manner (including available extensions of time) all reports and
other documents required to be filed by an issuer of securities registered under
the Exchange Act.

     USI has no material obligations or liabilities of any nature (matured or

provided for in the Balance Sheet included in USI's Quarterly Report on Form
10-Q heretofore provided to Soft Plus for the period ended September 30, 1999
(the "USI Balance Sheet"), (ii) those incurred in the ordinary course of
business and not required to be set forth in the USI Balance Sheet under GAAP,
and (iii) those incurred in the ordinary course of business since the USI
Balance Sheet Date and consistent with past practice.

     USI has complied with, is not in violation of, and has not received any
notices of violation with respect all applicable statutes, laws, ordinances,
rules and regulations except applicable statutes, laws, ordinances, rules and
regulations the non-compliance with which would cost $10,000 to correct or
satisfy the applicable penalty or fine on an individual basis or $100,000 in the
aggregate, or the non-compliance with which would not have a material adverse
effect on USI. No action, demand or investigation by any Governmental Entity and
no suit, action or proceeding by any Person, in each case with respect to USI or
any of its properties, is pending or, to the knowledge of USI, threatened that
could reasonably be expected to have an adverse effect on USI or impair the
ability of USI to perform its obligations under this Agreement or prevent or

of USI (an "Officer's Certificate") identifying Damages in the aggregate amount
in excess of the Indemnity Threshold has been delivered to the Escrow Agent and
the Soft Plus Shareholder Agent in accordance with the Escrow Agreement, in
which case USI shall receive Escrow Shares (valued at the USI Closing Date
Price) equal to the full amount of such Damages in excess of the Indemnity
Threshold in accordance with the terms and conditions of the Escrow Agreement.
If the USI Note is unpaid, and USI desires to make a claim of set-off against.
USI and the Soft Plus Shareholder Agent shall follow the procedures for notice
and dispute resolution set forth in the Escrow Agreement.

     12.5 Escrow Period.

     Subject to the following requirements, the Escrow Fund shall remain in
existence until the Escrow Termination Date (the "Escrow Period"). Upon the
expiration of the Escrow Period, the Escrow Fund shall terminate with respect to
all Escrow Shares; provided, however, that the number of Escrow Shares, which,
in the reasonable judgment of USI, subject to the objection of the Soft Plus
Shareholder Agent and the subsequent arbitration of the claim in the manner
provided in the Escrow Agreement, are necessary to satisfy any unsatisfied
claims specified in any Officer's Certificate delivered to the Escrow Agent
prior to the expiration of such Escrow Period with respect to facts and
circumstances existing on or prior to the Escrow Termination Date shall remain
in the Escrow Fund (and the Escrow Fund shall remain in existence) until such
claims have been resolved. As soon as all such claims have been resolved, the
Escrow Agent shall deliver to the Soft Plus Shareholders all Escrow Shares and
other property remaining in the Escrow Fund and not required to satisfy such
claims. Escrow Shares delivered to the Soft Plus Shareholder Agent pursuant to
this Section 12.5 for distribution to the Soft Plus Shareholders in proportion
to their respective interests may appear.

     12.6 Distributions; Voting.

          12.6.1 Any shares of USI Common Stock or other equity securities
issued or distributed by USI (including shares issued upon a stock split) ("New
Shares") in respect of the Escrow Shares that have not been released from the
Escrow Fund shall be added to the Escrow Fund and become a part thereof. When
and if cash dividends on Escrow Shares in the Escrow Fund shall be declared and
paid, they shall be distributed as soon as reasonably practicable to the
beneficial owners of the Escrow Shares. The beneficial owners of the Escrow
Shares shall pay any taxes on such dividends.

          12.6.2 Each Soft Plus Shareholder shall have voting rights with
respect to that number of Escrow Shares allocated to such Soft Plus Shareholder
in the Escrow Fund (and on any voting securities added to the Escrow Fund in
respect of such Escrow Shares) so long as such Escrow Shares or other voting
securities are held in the Escrow Fund. As the record holder of such shares, the

                                       52
<PAGE>

Escrow Agent shall vote such shares in accordance with the instructions of the
Soft Plus Shareholders having the beneficial interest therein and shall promptly
deliver copies of all proxy solicitation materials to such stockholders. USI
shall show the USI Common Stock contributed to the Escrow Fund as issued and
outstanding on its balance sheet.

     12.7 Method of Asserting Claims.

     All claims for indemnification by the Soft Plus Indemnitees or any other
Indemnified Person pursuant to this Article XII shall be made in accordance with
the provisions of the Escrow Agreement.

     12.8 Soft Plus Shareholder Agent; Power of Attorney.

     As of the Closing Date the Soft Plus Shareholder Agent shall be appointed
as agent and attorney-in-fact for each Soft Plus Shareholder (except such Soft
Plus Shareholders, if any, as shall have perfected their dissenters' rights
under California law), for and on behalf of Soft Plus Shareholders, to give and
receive notices and communications on behalf of the Soft Plus Shareholders, to
enter into and perform the Escrow Agreement, to authorize delivery to USI of the
Escrow Shares or other property from the Escrow Fund in satisfaction of claims
by USI or any other Indemnified Person, to object to such deliveries, to agree
to, negotiate, enter into settlements and compromises of, and demand arbitration
and comply with orders of courts and awards of arbitrators with respect to such
claims, and to take all actions necessary or appropriate in the judgment of the
Soft Plus Shareholder Agent for the accomplishment of the foregoing.

     12.9 Waiver of Contribution.

     The Principal Shareholders and the other Soft Plus Shareholders hereby
waive and disclaim any right of contribution or indemnity, whether under
contract or at law or in equity, against Acquisition or Soft Plus in connection
with any obligation of indemnification hereunder.

     12.10 Indemnity by USI.

           12.10.1 Subject to the limitations set forth in this Article XII,
from and after the Effective Time, USI agrees to indemnify and hold harmless
Soft Plus, and its affiliates, officers, directors, employees, representatives
and agents, acting in such capacity (each a "Corporate Soft Plus Indemnitee")
and each of the Soft Plus Shareholders, the Soft Plus Optionholders and the Soft
Plus Warrantholders (each a "Soft Plus Equity Holder Indemnitee," and together
with each Corporate Soft Plus Indemnitee hereafter referred to as a Soft Plus
Indemnitee) from, against, for and in respect of, and shall pay all Damages in
excess of the Indemnity Threshold suffered, sustained, incurred or required to
be paid by a Soft Plus Indemnitee with respect to any claim, demand, action or
cause of action during the Escrow Period by reason of, in connection with,
arising from or relating to any misrepresentation, breach of, or default in
connection with, any of the representations, warranties, covenants or agreements
of USI contained in this Agreement or any certificate delivered hereunder,
including any exhibits or schedules attached hereto, if any, and the Certificate
of Merger, but with respect to a Soft Plus Equity Holder only if such
representation, warranty, covenant or agreement of USI was made to such Soft
Plus Equity Holder Indemnitee, which breach becomes known to an Soft Plus
Indemnitee and is asserted in writing to USI on or before the Escrow Termination
Date, at which date this indemnification provision shall terminate. USI
hereunder shall have the right to satisfy Damages of a Soft Plus Indemnitee in

                                       53
<PAGE>

excess of the Indemnity Threshold by delivering shares of USI Common Stock
(valued at the USI Closing Date Price or cash, as USI elects, to the full amount
of such Damages in excess of the Indemnity Threshold.

           12.10.2 Damages of a Soft Plus Indemnitee in each case shall be net
of the amount of any insurance proceeds and indemnity and contribution actually
recovered by a Soft Plus Indemnitee.

           12.10.3 In no event shall USI's obligation hereunder to indemnify a
Soft Plus Indemnitee for Damages in excess of the Indemnity Threshold exceed an
amount in the aggregate equal to (X) the Indemnity Damages Limit, plus (Y) the
principal amount of the USI Note until such time that the USI Note is paid in
full, at which time the limitation of this Section 12.10.3 shall be the
Indemnity Damages Limit alone. Nothing in this Section 12.10.3 shall limit the
liability of USI for fraud or intentional misrepresentation of any
representations, warranties, covenants or agreements under this Agreement.

     12.11 Effect of Investigation.

     All statements contained in any certificate, Schedule or other instrument
delivered by or on behalf of the Principal Shareholders pursuant to this
Agreement or in connection with the transactions contemplated hereby shall be
deemed representations and warranties by the Principal Shareholders hereunder,
and no such representations or warranties, whether stated herein or in any
certificate, Schedule or other instrument delivered by or on behalf of the
Principal Shareholders pursuant to this Agreement or in connection with the
transactions contemplated hereby, shall be deemed waived or otherwise affected
by any investigation on the part of USI or Acquisition.

     12.12 Notice to the Indemnitor.

     Promptly after the assertion of any claim by a third-party or occurrence of
any event which may give rise to a claim for indemnification from a party
obligated to provide indemnification under this Article XII (an "Indemnitor"),
the party entitled to indemnification under this Article XII (the "Indemnified
Party") shall notify the Indemnitor in writing of such claim and advise the
Indemnitor of the estimated claim and whether the Indemnified Party intends to
contest the same (the "Indemnification Notice"), but the failure to give or
delay in giving such notice shall not affect the obligations of the Indemnitor
hereunder except to the extent the Indemnitor has been actually prejudiced
thereby.

     12.13 Rights of Parties to Settle or Defend.

     The Indemnified Party will permit the Indemnitor to assume the defense of
any such claim, or any litigation resulting therefrom. Counsel for the
Indemnitor, which will conduct the defense of such claim or litigation, must be
approved by the Indemnified Party, whose approval will not be unreasonably
withheld, and the Indemnified Party may participate in such defense at the
Indemnified Party's expense. If the Indemnitor determines not to contest such
claim within ten days of receiving the Indemnification Notice, the Indemnified
Party shall have the right, at the cost and expense of the Indemnitor, to
contest and defend against such claim. If the Indemnitor determines to contest
such claim, the Indemnified Party shall have the right to be represented, at its
own expense by its own counsel and accountants, their participation to be
subject to the reasonable direction of the Indemnitor. In either case, the

                                       54
<PAGE>

Indemnified Party shall make available to the Indemnitor and its attorneys and
accountants, at all reasonable times during normal business hours, all books,
records, and other documents in its possession relating to such claim. Any party
hereto contesting any such claim shall be furnished all reasonable assistance in
connection therewith by the other party hereto. If the Indemnitor fails to
undertake the defense of or settle or pay any such third-party claim within ten
days after receipt of an Indemnification Notice advising that the Indemnified
Party does not intend to contest such claim, or if the Indemnitor, after having
received such notification from the Indemnified Party, fails forthwith to
defend, settle or pay such claim, then the Indemnified Party may take any and
all necessary action to dispose of such claim, including, without limitation,
the settlement or full payment thereof upon such terms as it shall deem
appropriate, in its sole discretion, subject to Section 12.14 with respect to
any proposed settlement thereof.

     12.14 Settlement Proposals.

     If the Indemnified Party desires to settle any such third-party claim
(whether or not contested by the Indemnitor), the Indemnified Party shall advise
the Indemnitor of the amount it proposes to pay in settlement thereof (the
"Proposed Settlement"). If such Proposed Settlement is unsatisfactory to the
Indemnitor, it shall have the right, at its expense, to contest such claim by
giving written notice of such election to the Indemnified Party within ten days
after the Indemnitor has been advised of the Proposed Settlement. If the
Indemnitor does not deliver such written notice within ten days after the
Indemnitor has been advised of the Proposed Settlement, the Indemnified Party
may offer the Proposed Settlement to the third party making such claim. If the
Proposed Settlement is not accepted by the party making such claim, any new
Proposed Settlement that the Indemnified Party may wish to present to the party
making such claim shall first be presented to the Indemnitor who shall have the
right, subject to the conditions set forth in this Section 12.14, to contest
such claim. In all such events, the Indemnitor shall indemnify the Indemnified
Party and hold it harmless against and from any and all costs of defense,
payment or settlement, including reasonable attorneys' fees incurred in
connection therewith.

                       Article XIII. General Provisions.

     13.6 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 conflict of laws thereof.

     13.7 Dispute Resolution

          13.7.1 Informal Dispute Resolution. Any controversy between the
parties hereto ("Dispute") shall be resolved as follows:

                 13.7.1.1 Upon written request of either party, the Soft Plus
Shareholder Agent and a representative of USI will be to meet for the purpose of
endeavoring to resolve such Dispute. Each such designated representative shall
meet as often as the parties reasonably deem necessary to discuss the problem in
an effort to resolve the Dispute without the necessity of any formal proceeding.

                 13.7.1.2 If representatives of the parties are unable to
resolve the Dispute within 45 days after the Dispute is submitted to them, or if
after ten days either party determines in good faith prior to the expiration of
such period that such representatives are unlikely to be able to resolve such
matter, the Dispute shall be submitted to arbitration in accordance with Section
13.7.2.

          13.7.2 Arbitration. If the parties are unable to resolve the Dispute
as contemplated by Section 13.7.1 hereof, such Dispute shall be submitted to
mandatory and binding arbitration at the election of either party (the
"Disputing Party"), in such locale as the parties may agree, and if the parties
cannot agree, then in the City of St. Louis, MO. Except as otherwise provided in
this Section 13.7, the arbitration shall be pursuant to the Commercial
Arbitration Rules of the AAA. Within 15 days after a party delivers a written
demand for arbitration to the other party, the Soft Plus Shareholder Agent or
USI shall each select one arbitrator. The third arbitrator shall be selected as
soon as practicable by agreement of the first two arbitrators or, failing such
agreement, by the American Arbitration Association. The written decision of a
majority of the three arbitrators shall be binding and conclusive upon the
parties to this Agreement. The arbitrators shall award reimbursement to the
prevailing party in the arbitration of its reasonable expenses of the
arbitration (including costs and reasonable attorneys' fees). The award of the
arbitrators shall be the sole and exclusive monetary remedy of the parties and

                                       58
<PAGE>

shall be enforceable in any court of competent jurisdiction. Notwithstanding the
foregoing, any party shall be entitled to seek injunctive relief or other
equitable remedies from any court of competent jurisdiction.

     13.8 Assignment.

     Neither this Agreement nor any of the rights, interests or obligations
under this Agreement shall be assigned, in whole or in part, by operation of law
or otherwise by any of the parties hereto without the prior written consent of
the other parties. Any assignment in violation of the preceding sentence shall
be void. Subject to the preceding two sentences, this Agreement will be binding
upon, inure to the benefit of, and be enforceable by, the parties and their
respective successors and assigns.

     13.9 Enforcement.

     The parties agree that irreparable damage would occur and that the parties
would not have any adequate remedy at law 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 an injunction or injunctions to prevent breaches of
this Agreement and to enforce specifically the terms and provisions of this
Agreement in any federal court located in the State of Delaware or in 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

          13.9.1 consents to submit himself or itself 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 by this Agreement,

          13.9.2 agrees that it will not attempt to deny or defeat such personal
jurisdiction by motion or other request for leave from any such court, and

          13.9.3 agrees that it will not bring any action relating to this
Agreement or any of the transactions contemplated by this Agreement in any court
other than a federal court sitting in the State of Delaware or a Delaware state
court subject to the provisions of Section 13.7.

     13.10 Headings.

     The headings contained in this Agreement are for reference purposes only
and shall not affect in any way the meaning or interpretation of this Agreement.

     13.11 Severability.

     If any term or other provision of this Agreement is held by a court of
competent jurisdiction or other Governmental Entity to be invalid, illegal or
incapable of being enforced by any rule of law or public policy, all other
conditions and provisions of this Agreement shall nevertheless remain in full
force and effect. Upon such determination that any term or other provision is
invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible to the fullest extent permitted by
applicable law in an acceptable manner to the end that the transactions
contemplated hereby are fulfilled to the extent possible.

time periods set forth or referred to in this Agreement, time is of the essence.
