                     AGREEMENT AND PLAN OF REORGANIZATION

    
    This AGREEMENT AND PLAN OF REORGANIZATION (the "AGREEMENT") is made and
entered into effective as of August 29, 1997 by and among Peregrine Systems,
Inc., a Delaware corporation (the "PARENT"); French Acquisition Corporation, a
Delaware corporation and wholly-owned subsidiary of Parent (the "MERGER SUB");
United Software, Inc., a Delaware corporation (the "COMPANY"); Vincent Worms as
Securityholder Agent; ChaseMellon Shareholder Services, LLC as Escrow Agent; and
for purposes of Sections 2.1(b), 2.2, and 2.3(b) of Article II and Sections 6.10
and 6.20 of Article VI, certain stockholders of the Company listed on EXHIBIT A
attached hereto (the "AFFILIATE STOCKHOLDERS").

                                   RECITALS

    A.   On August 29, 1997, the Boards of Directors of each of the Company and
Parent authorized the officers of the Company and Parent, respectively, to
execute and deliver a Memorandum of Understanding (the "Memorandum") setting
forth the terms and conditions upon which Parent would acquire the Company
through the statutory merger of Merger Sub with and into the Company (the
"Merger") and directed such officers to negotiate, execute, and deliver this
Agreement to memorialize the terms of the Merger set forth in the Memorandum. 

    B.   The Boards of Directors of each of the Company, Parent, and Merger Sub
believe it to be in the best interests of each such company and their respective
stockholders that the parties consummate the Merger.  

    C.   Pursuant to the Merger, among other things, and subject to the terms
and conditions of this Agreement, all of the issued and outstanding shares of
the Company's capital stock ("COMPANY CAPITAL STOCK") and all outstanding
options and other rights to acquire or receive shares of Company Capital Stock
shall be converted into the right to receive shares of Parent's Common Stock,
$0.001 par value per share ("PARENT COMMON STOCK"), at the rate determined
herein.

    D.   A portion of the shares of Parent Common Stock otherwise issuable by
Parent in connection with the Merger shall be placed in escrow by Parent, the
release of which amount shall be contingent upon certain events and conditions,
all as set forth in Article VIII hereof.

    E.   The Company, Parent, Merger Sub, and the Affiliate Stockholders desire
to make certain representations and warranties and other agreements in
connection with the Merger.

    F.   The parties intend, by executing this Agreement, to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended (the "Code").

<PAGE>

    NOW, THEREFORE, in consideration of the covenants, promises, and
representations set forth herein, and for other good and valuable consideration,
intending to be legally bound hereby, the parties agree as follows:


                                   ARTICLE I

                                  THE MERGER

    1.1  THE MERGER.  At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement and the
applicable provisions of the Delaware General Corporation Law ("Delaware Law"),
Merger Sub shall be merged with and into the Company, the separate corporate
existence of Merger Sub shall cease, and the Company shall continue as the
surviving corporation and as a wholly-owned subsidiary of Parent.  The Company
as the surviving corporation after the Merger is hereinafter sometimes referred
to as the "SURVIVING CORPORATION."

    1.2  EFFECTIVE TIME.  Unless this Agreement is earlier terminated pursuant
to Article X, the closing of the Merger (the "CLOSING") will take place as
promptly as practicable but no later than five (5) business days following
satisfaction or waiver of the conditions set forth in Article VII at the offices
of Wilson Sonsini Goodrich & Rosati, Professional Corporation, 650 Page Mill
Road, Palo Alto, California 94304-1050, unless another place or time is agreed
to by Parent and the Company.  The date upon which the Closing actually occurs
is referred to herein as the "CLOSING DATE."  On the Closing Date, the parties
hereto shall cause the Merger to be consummated by filing a Certificate of
Merger (or like instrument) with the Secretary of State of the State of Delaware
(the "CERTIFICATE OF MERGER"), in accordance with the relevant provisions of
applicable law (the time of acceptance by the Secretary of State of Delaware of
such filing being referred to herein as the "EFFECTIVE TIME").  

    1.3  EFFECT OF THE MERGER.  At the Effective Time, the effect of the Merger
shall be as provided in the applicable provisions of Delaware Law.  Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, all the property, rights, privileges, powers, and franchises of the
Company and Merger Sub shall vest in the Surviving Corporation, and all debts,
liabilities and duties of the Company and Merger Sub shall become the debts,
liabilities, and duties of the Surviving Corporation.

    1.4  CERTIFICATE OF INCORPORATION; BYLAWS.

         (a)  Unless otherwise determined by Parent prior to the Effective
Time, at the Effective Time, the Certificate of Incorporation of Merger Sub
shall be the Certificate of Incorporation of the Surviving Corporation until
thereafter amended as provided by law and such Certificate of Incorporation;
PROVIDED, HOWEVER, that Article I of the Certificate of Incorporation of the
Surviving Corporation shall be amended to read as follows:  "The name of the
corporation is Peregrine Asset Management Corporation."

                                      -2-

<PAGE>

         (b)  The Bylaws of Merger Sub, as in effect immediately prior to the 
Effective Time, shall be the Bylaws of the Surviving Corporation until 
thereafter amended.

    1.5  DIRECTORS AND OFFICERS.  The director(s) of Merger Sub immediately 
prior to the Effective Time shall be the initial director(s) of the Surviving 
Corporation, each to hold office in accordance with the Certificate of 
Incorporation and Bylaws of the Surviving Corporation.  The officers of 
Merger Sub immediately prior to the Effective Time shall be the initial 
officers of the Surviving Corporation, each to hold office in accordance with 
the Bylaws of the Surviving Corporation.

    1.6  EFFECT ON CAPITAL STOCK.  Subject to the terms and conditions of 
this Agreement, as of the Effective Time, by virtue of the Merger and without 
any action on the part of Merger Sub, the Company, or the holder of any 
shares of the Company Capital Stock, the following shall occur:

         (a)  AGGREGATE SHARES OF PARENT COMMON STOCK.   The aggregate 
maximum number of shares of Parent Common Stock to be issued (including 
Parent Common Stock to be reserved for issuance upon exercise of any of the 
Company's options and warrants to be assumed by Parent) in exchange for the 
acquisition by Parent of all outstanding Company Capital Stock and all 
unexpired and unexercised options and warrants to acquire Company Capital 
Stock (the "AGGREGATE SHARES OF PARENT COMMON STOCK") shall not exceed the 
sum of (i) 1,891,051 and (ii) the number of shares of Incremental Parent 
Common Stock (as defined below).

         (b)  CONVERSION OF COMPANY COMMON STOCK.  Each share of Common Stock 
of the Company ("COMPANY COMMON STOCK") issued and outstanding immediately 
prior to the Effective Time, including all shares of Common Stock issued and 
outstanding as a result of the conversion of the Company's Series A Preferred 
Stock or Series B Preferred Stock (collectively, the "COMPANY PREFERRED 
STOCK") immediately prior to the Effective Time as contemplated by Section 
6.1(b) but excluding any shares of Company Capital Stock to be cancelled 
pursuant to Section 1.6(d) and any Dissenting Shares (as defined and to the 
extent provided in Section 1.7(a)), will be cancelled and extinguished and 
will be converted automatically into the right to receive 0.234829 shares of 
Parent Common Stock (the "BASE EXCHANGE RATIO"). 

         Of the total shares of Parent Common Stock issued pursuant to this 
Section 1.6(b), ten percent (10%) shall be subject to the Escrow pursuant to 
Article VIII below (with fractional shares as to any Stockholder to be 
rounded down to a whole share) (the "ESCROW AMOUNT").

         (c)  INCREMENTAL EXCHANGE RATIO.  In addition to the shares of 
Parent Common Stock to be issued based on the Base Exchange Ratio in 
accordance with the provisions of Section 1.6(b) above, each share of Company 
Common Stock issued and outstanding immediately prior to the Effective Time, 
including all shares issued and outstanding as a result of the conversion of 
the Company Preferred Stock immediately prior to the Effective Time as 
contemplated by Section 6.1(b) but excluding any shares of Company Capital 
Stock to be cancelled pursuant to Section 1.6 (d) and any Dissenting Shares, 
will be entitled to receive that fraction of a share of Parent Common Stock as


                                       3

<PAGE>

is equal to the Incremental Exchange Ratio (as defined herein), none of 
which shares (the "INCREMENTAL PARENT COMMON STOCK") shall be included in the 
Escrow Amount.  The Incremental Exchange Ratio as used herein shall mean the 
quotient (expressed as a decimal and rounded out to the nearest millionth of 
a share of Parent Common Stock) that results from a fraction, the denominator 
of which is the Total Company Common Stock (as defined herein) and the 
numerator of which is itself a fraction, the numerator of which is Five 
Hundred Thousand Dollars ($500,000) and the denominator of which is the per 
share closing price of Parent Common Stock as of the second day immediately 
preceding the Effective Time as reported on the Nasdaq National Market.  The 
Total Company Common Stock as used herein shall mean the aggregate Company 
Common Stock outstanding immediately prior to the Effective Time, including 
(i) all Company Common Stock issued as a result of the conversion of the then 
outstanding Company Preferred Stock, (ii) all Company Common Stock issuable 
upon exercise of the then outstanding options and other rights to acquire 
Company Common Stock (whether or not they are exercisable) and (iii) all 
Company Common Stock that would be issuable on a one-for-one basis in respect 
of the 68,000 shares of Common Stock of Apsylog (as defined in Section 6.15) 
held by the Apsylog Minority Stockholder (as defined in Section 6.15(a) 
below).  For purposes of this Agreement, reference to the Parent Common Stock 
to be issued in connection with the Merger at the Effective Time shall be 
deemed to include the Incremental Parent Common Stock, unless otherwise 
specified.  The "Base Exchange Ratio" and the "Incremental Exchange Ratio," 
when cumulated and added together, are referred to herein as the "COMMON 
EXCHANGE RATIO."

         (d)  CANCELLATION OF PARENT-OWNED AND COMPANY-OWNED STOCK.  Each 
share of Company Capital Stock owned by Merger Sub, Parent, the Company or 
any direct or indirect wholly-owned subsidiary of Parent or subsidiary of the 
Company immediately prior to the Effective Time shall be cancelled and 
extinguished without any conversion thereof.

         (e)  STOCK OPTIONS.  At the Effective Time, all options and stock 
purchase rights to purchase Company Common Stock (each a "Company Option") 
then outstanding under the Company's 1997 Stock Plan (the "OPTION PLAN") 
(whether or not exercisable and whether or not vested), or otherwise, shall 
remain outstanding following the Effective Time and shall be assumed by 
Parent in accordance with provisions described below.

              (i)   Each Company Option so assumed by Parent under this 
Agreement shall continue to have, and be subject to, the same terms and 
conditions set forth in the Option Plan and/or as provided in the respective 
option agreements including any amendments thereto permitted by the Agreement 
governing such Company Option immediately prior to the Effective Time, except 
that (A) such Company Option shall be exercisable for that number of whole 
shares of Parent Common Stock equal to the product of the number of shares of 
Company Common Stock that were issuable upon exercise of such Company Option 
immediately prior to the Effective Time multiplied by the Common Exchange 
Ratio, rounded up to the nearest whole number of shares of Parent Common 
Stock and (B) the per share exercise price for the shares of Parent Common 
Stock issuable upon exercise of such assumed Company Option shall be equal to 
the quotient determined by dividing the exercise price per share of Company 
Common Stock at which such Company Option was exercisable 


                                       4

<PAGE>

immediately prior to the Effective Time by the Common Exchange Ratio, rounded 
up to the nearest whole cent.  Parent acknowledges and agrees that the 
Company and each optionee will amend each Company Option prior to the 
Effective Time to provide that such Company Options will become fully vested 
and exercisable with respect to all shares subject thereto immediately prior 
to the Effective Time.

              (ii)  It is the intention of the parties that the Company 
Options assumed by Parent qualify following the Effective Time as incentive 
stock options as defined in Section 422 of the Code to the extent the Company 
Options qualified as incentive stock options immediately prior to the 
Effective Time.

              (iii) Promptly following the Effective Time, Parent will issue 
to each holder of an outstanding Company Option a document evidencing the 
foregoing assumption of such Company Option by Parent. 

              (iv)  Prior to the Effective Time, the Company shall deliver to 
each holder of shares of Company Capital Stock outstanding immediately prior 
to the Effective Time which are then unvested or subject to a repurchase 
option, risk of forfeiture, or other condition under any applicable 
restricted stock purchase agreement or other agreement with the Company, a 
written notice to the effect that the Company has waived its right (and 
terminated such holder's obligations with respect) to such repurchase option, 
risk of forfeiture, or similar condition such that such shares shall be fully 
vested immediately prior to the Effective Time.  The Company shall also 
deliver to each holder of unvested Company Options written notice that such 
Company Options shall become fully vested and exercisable with respect to all 
shares subject thereto immediately prior to the Effective Time. 

              (v)   Notwithstanding anything to the contrary in this Section 
1.6, in lieu of assuming outstanding Company Options in accordance with 
Section 1.6(d), Parent may, at its election, cause such outstanding Company 
Options to be replaced by issuing substantially equivalent replacement stock 
options in substitution therefor.

         (f)  CAPITAL STOCK OF MERGER SUB.  Each share of Common Stock of 
Merger Sub issued and outstanding immediately prior to the Effective Time 
shall be converted into and exchanged for one validly issued, fully paid, and 
nonassessable share of Common Stock of the Surviving Corporation.  Each stock 
certificate of Merger Sub evidencing ownership of any such shares shall 
continue to evidence ownership of such shares of capital stock of the 
Surviving Corporation.

         (g)  ADJUSTMENTS TO EXCHANGE RATIOS.  The Common Exchange Ratio 
shall be adjusted to reflect fully the effect of any stock split, reverse 
split, stock dividend (including any dividend or distribution of securities 
convertible into Parent Common Stock or Company Capital Stock), 
reorganization, recapitalization or other like change with respect to Parent 
Common Stock or Company Capital Stock occurring after the date hereof and 
prior to the Effective Time, other than the


                                       5

<PAGE>


conversion of the Company Preferred Stock into Company Common Stock prior to 
the Effective Time.

         (h)  FRACTIONAL SHARES.  No fraction of a share of Parent Common 
Stock will be issued, but in lieu thereof, each holder of shares of Company 
Capital Stock who would otherwise be entitled to a fraction of a share of 
Parent Common Stock (after aggregating all fractional shares of Parent Common 
Stock to be received by such holder) shall be entitled to receive from Parent 
an amount of cash (rounded to the nearest whole cent) equal to the product of 
(i) such fraction and (ii) the Parent Price Per Share (as defined in Section 
8.2(d)(ii)).

    1.7  APPRAISAL RIGHTS.
    
         (a)  Notwithstanding any provision of this Agreement to the 
contrary, any shares of Company Capital Stock held by a holder who has 
demanded and perfected appraisal rights for such shares in accordance with 
Delaware Law and who, as of the Effective Time, has not effectively withdrawn 
or lost such appraisal rights ("DISSENTING SHARES"), shall not be converted 
into or represent a right to receive Parent Common Stock pursuant to Section 
1.6, but the holder thereof shall only be entitled to such rights as are 
granted by Delaware Law.
    
         (b)  Notwithstanding the provisions of subsection (a), if any holder 
of shares of Company Capital Stock who demands appraisal of such shares under 
Delaware Law shall effectively withdraw or lose (through failure to perfect 
or otherwise) the right to appraisal, then, as of the later of the Effective 
Time or the occurrence of such event, such holder's shares shall 
automatically be converted into and represent only the right to receive 
Parent Common Stock and fractional shares as provided in Section 1.6, without 
interest thereon, upon surrender of the certificate representing such shares 
of Company Capital Stock.
    
         (c)  The Company shall give Parent (i) prompt notice of any written 
demands for appraisal of any shares of Company Capital Stock, withdrawals of 
such demands, and any other instruments served pursuant to Delaware Law and 
received by the Company and (ii) the opportunity to participate in all 
negotiations and proceedings with respect to demands for appraisal under 
Delaware Law.  The Company shall not, except with the prior written consent 
of Parent, voluntarily make any payment with respect to any demands for 
appraisal of Company Capital Stock or offer to settle or settle any such 
demands.
    
    1.8  SURRENDER OF CERTIFICATES.
    
         (a)  EXCHANGE AGENT.  ChaseMellon Shareholder Services, LLC shall 
act as exchange agent (the "EXCHANGE AGENT") in the Merger.
    
         (b)  PARENT TO PROVIDE COMMON STOCK.  Promptly after the Effective 
Time, Parent shall make available to the Exchange Agent for exchange in 
accordance with this Article I, the aggregate number of shares of Parent 
Common Stock issued pursuant to Section 1.6 in exchange for 


                                       6

<PAGE>


outstanding shares of Company Capital Stock; provided that, on behalf of the 
holders of Company Capital Stock, Parent shall deposit into an escrow account 
a number of shares of Parent Common Stock equal to the Escrow Amount out of 
the aggregate number of shares of Parent Common Stock otherwise issuable 
pursuant to Section 1.6(b). The portion of the Escrow Amount contributed on 
behalf of each holder of Company Capital Stock shall be in proportion to the 
aggregate number of shares of Parent Common Stock which such holder would 
otherwise be entitled to receive under Section 1.6(b) by virtue of ownership 
of outstanding shares of Company Capital Stock immediately prior to the 
Effective Time.
    
         (c)  EXCHANGE PROCEDURES.  Promptly after the Effective Time, the 
Surviving Corporation shall cause to be mailed to each holder of record of a 
certificate or certificates (the "CERTIFICATES") which immediately prior to 
the Effective Time represented outstanding shares of Company Capital Stock 
whose shares were converted into the right to receive shares of Parent Common 
Stock pursuant to Section 1.6, (i) a letter of transmittal (which shall 
specify that delivery shall be effected, and risk of loss and title to the 
Certificates shall pass, only upon delivery of the Certificates to the 
Exchange Agent and shall be in such form and have such other provisions as 
Parent may reasonably specify) and (ii) instructions for use in effecting the 
surrender of the Certificates in exchange for certificates representing 
shares of Parent Common Stock.  Upon surrender of a Certificate for 
cancellation to the Exchange Agent or to such other agent or agents as may be 
appointed by Parent, together with such letter of transmittal, duly completed 
and validly executed in accordance with the instructions thereto, the holder 
of such Certificate shall be entitled to receive in exchange therefor a 
certificate representing the number of whole shares of Parent Common Stock 
(less the number of shares of Parent Common Stock, if any, to be deposited in 
the Escrow Fund (as defined in Section 8.2) on such holder's behalf pursuant 
to Article VIII hereof), plus cash in lieu of fractional shares in accordance 
with Section 1.6, to which such holder is entitled pursuant to Section 1.6, 
and the Certificate so surrendered shall forthwith be cancelled.  As soon as 
practicable after the Effective Time, and subject to and in accordance with 
the provisions of Article VIII hereof, Parent shall cause to be distributed 
to the Escrow Agent (as defined in Article VIII) a certificate or 
certificates representing that number of shares of Parent Common Stock equal 
to the Escrow Amount which shall be registered in the name of the Escrow 
Agent.  Such shares shall be beneficially owned by the holders on whose 
behalf such shares were deposited in the Escrow Fund and shall be available 
to compensate Parent as provided in Article VIII.  Until so surrendered, each 
outstanding Certificate that, prior to the Effective Time, represented shares 
of Company Capital Stock will be deemed from and after the Effective Time, 
for all corporate purposes, to evidence the ownership of the number of full 
shares of Parent Common Stock into which such shares of Company Capital Stock 
shall have been so converted and the right to receive an amount in cash in 
lieu of the issuance of any fractional share in accordance with Section 1.6.
    
         (d)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No dividends 
or other distributions declared or made after the Effective Time with respect 
to Parent Common Stock with a record date after the Effective Time will be 
paid to the holder of any unsurrendered Certificate with respect to the 
shares of Parent Common Stock represented thereby until the holder of record 
of such Certificate shall surrender such Certificate.  Subject to applicable 
law, following surrender of any 


                                       7

<PAGE>

such Certificate, there shall be paid to the record holder of the 
certificates representing whole shares of Parent Common Stock issued in 
exchange therefor, without interest, at the time of such surrender, the 
amount of dividends or other distributions with a record date after the 
Effective Time theretofore paid with respect to such whole shares of Parent 
Common Stock.
    
         (e)  TRANSFERS OF OWNERSHIP.  If any certificate for shares of 
Parent Common Stock is to be issued in a name other than that in which the 
certificate surrendered in exchange therefor is registered, it will be a 
condition of the issuance thereof that the certificate so surrendered will be 
properly endorsed and otherwise in proper form for transfer and that the 
person requesting such exchange will have paid to Parent or any agent 
designated by it any transfer or other taxes required by reason of the 
issuance of a certificate for shares of Parent Common Stock in any name other 
than that of the registered holder of the certificate surrendered, or 
established to the satisfaction of Parent or any agent designated by it that 
such tax has been paid or is not payable.
    
         (f)  NO LIABILITY.  Notwithstanding anything to the contrary in this 
Section 1.8, none of the Exchange Agent, the Surviving Corporation, or any 
party hereto shall be liable to a holder of shares of Parent Common Stock or 
Company Capital Stock for any amount properly paid to a public official 
pursuant to any applicable abandoned property, escheat, or similar law.
    
    1.9  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  All shares of 
Parent Common Stock issued upon the surrender for exchange of shares of 
Company Common Stock in accordance with the terms hereof (including any cash 
paid in respect thereof) shall be deemed to have been issued in full 
satisfaction of all rights pertaining to such shares of Company Common Stock, 
and there shall be no further registration of transfers on the records of the 
Surviving Corporation of shares of Company Common Stock which were 
outstanding immediately prior to the Effective Time.  If, after the Effective 
Time, Certificates are presented to the Surviving Corporation for any reason, 
they shall be cancelled and exchanged as provided in this Article I.
    
    1.10 LOST, STOLEN, OR DESTROYED CERTIFICATES.  In the event any 
certificate evidencing shares of Company Capital Stock shall have been lost, 
stolen, or destroyed, the Exchange Agent shall issue in exchange for such 
lost, stolen or destroyed certificate, upon the making of an affidavit of 
that fact by the holder thereof, such shares of Parent Common Stock and cash 
for fractional share, if any, as may be required pursuant to Section 1.6; 
PROVIDED, HOWEVER, that Parent may, in its discretion and as a condition 
precedent to the issuance thereof, require the owner of such lost, stolen or 
destroyed certificate to deliver a bond in such sum as it may reasonably 
direct as indemnity against any claim that may be made against Parent or the 
Exchange Agent with respect to the certificate alleged to have been lost, 
stolen or destroyed.
    
    1.11 TAX AND ACCOUNTING CONSEQUENCES.  It is intended by the parties 
hereto that the Merger shall (i) constitute a reorganization within the 
meaning of Section 368 of the Code and (ii) qualify for accounting treatment 
as a purchase.

    1.12 TAKING OF NECESSARY ACTION; FURTHER ACTION.  If, at any time after 
the Effective Time, any such further action is necessary or desirable to 
carry out the purposes of this Agreement and to vest the Surviving 
Corporation with full right, title, and possession to all assets, property, 
rights, privileges, powers, and franchises of the Company and Merger Sub, the 
officers and directors of the Company and Merger Sub are fully authorized in 
the names of their respective corporations or otherwise to take, and will 
take, all such lawful and necessary action.


                                  ARTICLE II
                                       
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
                        AND THE AFFILIATE STOCKHOLDERS
                                       
    The Company hereby represents and warrants, and, for purposes of Sections 
2.1(b) and 2.2,  the Company and, to the best of their knowledge, each of the 
Affiliate Stockholders, severally, hereby represent and warrant, and, for 
purposes of Section 2.3(b), each Affiliate Stockholder severally hereby 
represents and warrants with respect to such Affiliate Stockholder, to Parent 
and Merger Sub, subject to the specific exceptions disclosed in the 
disclosure letter and schedules thereto (each referencing the appropriate 
section numbers of this Article II as to which an exception exists) delivered 
by the Company and the Affiliate Stockholders to Parent (the "Company 
Schedules") and dated as of the date hereof, as follows:
    
    2.1  ORGANIZATION OF THE COMPANY.

         (a)  The Company is a corporation duly organized, validly existing, 
and in good standing under the laws of the State of Delaware, and each 
Subsidiary (as defined herein) is a corporation duly organized, validly 
existing, and in good standing under the laws of its respective jurisdiction 
of incorporation.  The Company and each Subsidiary has the corporate power 
and authority to own, lease, and operate its assets and property and to carry 
on its business as now being conducted and as proposed to be conducted and is 
duly qualified or licensed to do business and is in good standing in each 
jurisdiction where the character of the properties owned, leased, or operated 
by it or the nature of its activities makes such qualification or licensing 
necessary, except where the failure to be so qualified would not have a 
material adverse effect on the condition (financial or otherwise), business, 
net worth, assets (including intangible assets), properties, operations, 
obligations, liabilities (fixed or contingent), or prospects ("Material 
Adverse Effect") of the Company or such Subsidiary.

         (b)  Schedule 2.1(b) sets forth a complete list of each corporation, 
partnership, limited liability company, joint venture, business trust or 
association, or other entity in which the Company, directly or indirectly, 
holds an equity interest (each, a "Subsidiary" and collectively, the 
"Subsidiaries"). The term "Subsidiary" shall not include Apsylog (UK) Ltd., a 
corporation organized under the laws of England and, except for the 
representations made in this Section 2.1(b), A-Net and Net (as defined in 
Section 6.15(a)).  Schedule 2.1(b) identifies for each Subsidiary the issued 
and 


                                       9

<PAGE>


outstanding capital stock, the identity and address of each holder of the 
issued and outstanding capital stock of such Subsidiary, and the number of 
shares of capital stock of each Subsidiary held by such holder (as updated 
prior to the Closing to reflect the transactions contemplated by Section 
6.15(a)).  Except as set forth in Schedule 2.1(b), and in any event without 
exception prior to the Closing, all of the outstanding shares of the capital 
stock of each Subsidiary have been duly authorized and validly issued, are 
fully paid and nonassessable, and are wholly owned by the Company, directly 
or indirectly through a Subsidiary, free and clear of any lien, adverse 
claim, security interest, equity or other encumbrance.  Except as described 
in Schedule 2.1(b), there are no options, warrants, calls, rights, 
commitments or agreements of any character, written or oral, to which any 
Subsidiary is a party or by which any Subsidiary is bound, obligating such 
Subsidiary to issue, deliver, sell, repurchase or redeem, or cause to be 
issued, delivered, sold, repurchased or redeemed, any shares of such 
Subsidiary's capital stock.

         (c)  The Company has made available to Parent a true and correct 
copy of its Certificate of Incorporation and Bylaws and similar constituent 
documents of each Subsidiary, each as amended to date, and each such 
instrument is in full force and effect.  Neither the Company nor any 
Subsidiary is in violation of any of the provisions of its Certificate of 
Incorporation or Bylaws or equivalent governing instruments.
    
    2.2  COMPANY CAPITAL STRUCTURE.
    
         (a)  The authorized Company Capital Stock consists of 15,000,000 
shares of authorized Common Stock, par value $0.001 per share, of which 
1,941,066 shares are issued and outstanding, and 10,000,000 shares of 
authorized Preferred Stock, par value $0.001 per share.  Of the authorized 
Preferred Stock, 3,898,084 shares have been designated as Series A Preferred 
Stock, of which 819,101 shares are issued and outstanding, and 2,009,530 
shares have been designated as Series B Preferred Stock, of which 2,009,530 
shares are issued and outstanding.  The Company Capital Stock is held of 
record by the persons with the addresses of record and in the amounts 
identified on Schedule 2.2(a). Immediately after giving effect to the 
transactions contemplated by Section 6.15(a) of this Agreement, the Company 
will have issued and outstanding 1,941,066 shares of Common Stock (not 
including 68,000 shares which may be issued to the Apsylog Minority Holder as 
defined in Section 6.15(a) below), 3,898,084 shares of Series A Preferred 
Stock, and 2,009,530 shares of Series B Preferred Stock.  All outstanding 
shares of Company Capital Stock are (and any shares issued pursuant to the 
transactions contemplated by Section 6.15(a) will be) duly authorized, 
validly issued, fully paid, and non-assessable and not subject to preemptive 
rights created by statute, the Certificate of Incorporation or Bylaws of the 
Company or any agreement or document to which the Company is a party or by 
which it is bound.  Each outstanding share of Company Preferred Stock is 
presently convertible into one share of Company Common Stock. Except as 
described in Schedule 2.2(b) or Schedule 2.2(c), there are no options, 
warrants, calls, rights, commitments or agreements of any character, written 
or oral, to which the Company is a party or by which it is bound obligating 
the Company to issue, deliver, sell, repurchase or redeem, or cause to be 
issued, delivered, sold, repurchased or redeemed, any shares of Company 
Capital Stock. 


                                       10

<PAGE>

         (b)  Of the 1,941,066 shares of Company Common Stock outstanding, 
1,563,708 shares were issued pursuant to restricted stock purchase agreements 
granting repurchase options in favor of the Company in the event of a 
termination of employment ("Restricted Stock").  Schedule 2.2(b) identifies 
each employee of the Company or any Subsidiary who holds Restricted Stock and 
specifies the vesting schedule for such Restricted Stock, the extent to which 
such shares of Restricted Stock are vested to date, and whether the vesting 
of such Restricted Stock will accelerate as a result of the transactions 
contemplated by this Agreement.
    
         (c)  The Company has reserved 1,000,000 shares of Common Stock for 
issuance to employees and consultants pursuant to the Option Plan, of which 
134,500 shares are subject to outstanding, unexercised options and 488,142 
shares remain available for future grant.  Schedule 2.2(c) sets forth for 
each outstanding Company Option the name of the holder of such option, the 
address of such holder, the number of shares of Common Stock subject to such 
option, the exercise price and the vesting schedule of such option, including 
the extent vested to date, and whether the exercisability of such option will 
be accelerated and become exercisable by the transactions contemplated by 
this Agreement.  Except as described in Schedule 2.2(c), there are no 
options, warrants, calls, rights, commitments or agreements of any character, 
written or oral, to which the Company is a party or by which it is bound 
obligating the Company to grant, extend, accelerate the vesting of, change 
the price of, otherwise amend or enter into any such option, warrant, call, 
right, commitment, or agreement.  The holders of Company Options or any other 
options or rights set forth in Schedule 2.2(c) have been or will be given, or 
shall have properly waived, any required notice prior to the Merger.

         (d)  As a result of the Merger, Parent will be the record and sole 
beneficial owner of all outstanding Company Capital Stock and all rights to 
acquire or receive Company Capital Stock.  At or before the Effective Time, 
any rights of any holder or prospective holder of the Company's securities to 
cause such securities to be registered under the United States Securities Act 
of 1933, as amended (the "Securities Act"), and any information rights, 
voting rights, rights of co-sale, rights to maintain equity percentage, 
rights of first refusal and the like that may exist for the benefit of any 
such holder or prospective holder shall have been terminated, except as 
expressly contemplated by this Agreement.  
    
    2.3  AUTHORITY. 

         (a)  The Company has all requisite corporate power and authority to 
enter into this Agreement and to consummate the transactions contemplated 
hereby.  The execution and delivery of this Agreement and the consummation of 
the transactions contemplated hereby have been duly authorized by all 
necessary corporate action on the part of the Company, subject only to the 
approval of the Merger by the Company's stockholders.  The vote required of 
the Company's stockholders to duly approve the Merger is a majority of the 
outstanding shares of Company Common Stock and a majority of the outstanding 
shares of Company Preferred Stock, each voting as a separate class (in each 
case with each share of Company Preferred Stock being entitled to a number of 
votes equal to the number of whole shares of Company Common Stock into which 
such share of Company 


                                       11

<PAGE>


Preferred Stock could be converted on the  record date for the vote).  The 
Company's Board of Directors has unanimously approved the Merger and this 
Agreement.  This Agreement has been duly executed and delivered by the 
Company and constitutes the valid and binding obligation of the Company, 
enforceable in accordance with its terms.  Except as set forth on Schedule 
2.3(a), subject only to the approval of the Merger by the Company's 
stockholders, the execution and delivery of this Agreement by the Company and 
the Affiliate Stockholders does not, and, as of the Effective Time, the 
consummation of the transactions contemplated hereby will not, conflict with, 
or result in any violation of, or default under (with or without notice or 
lapse of time, or both), or give rise to a right of termination, cancellation 
or acceleration of any obligation or loss of any benefit under (any such 
event, a "CONFLICT") (i) any provision of the Certificate of Incorporation or 
Bylaws of the Company or (ii) any mortgage, indenture, lease, contract or 
other agreement or instrument, permit, concession, franchise, license,

    2.4  COMPANY FINANCIAL STATEMENTS.

         (a)  (i) The audited unconsolidated statements of income of each 
Subsidiary for each of the fiscal years ended December 31, 1995 and December 
31, 1996, (ii) the audited unconsolidated balance sheets of each Subsidiary 
at December 31 for each such fiscal year, (iii) the unaudited consolidated 
statements of income of Apsylog for the six months ended June 30, 1997, and 
(iv) the audited consolidated balance sheet of Apsylog at June 30, 1997 are 
complete and correct in all material respects, have been prepared in 
accordance with generally accepted accounting principles ("GAAP") in France 
applied on a consistent basis throughout the periods indicated (except that 
the financial statements do not have notes thereto), and fairly present the 
consolidated financial position of Apsylog and its consolidated results of 
operations and the financial position and results of operations of each 
Subsidiary, as the case may be, as of the respective dates and for the 
respective periods indicated, subject, in the case of the unaudited financial 
statements, to normal year-end adjustments.  The Company's audited balance 
sheet at June 30, 1997 is hereinafter referred to as the "Company Balance 
Sheet," and all such financial statements are hereinafter referred to as the 
"Company Financial Statements."

         (b)  No Subsidiary has any liability, indebtedness, obligation, 
expense, claim, deficiency, guaranty or endorsement of any type, whether 
accrued, absolute, contingent, matured, unmatured or other (whether or not 
required to be reflected in the Company Financial Statements in accordance 
with GAAP) which (i) has not been reflected in the Company Balance Sheet or 
(ii) has not arisen in the ordinary course of the Company's business since 
June 30, 1997 consistent in nature and amount with past practices and which 
does not exceed $15,000 individually or $45,000 in the aggregate.

         (c)  A true and correct copy of the Company Financial Statements is 
attached to the Company Schedules as Schedule 2.4 (c).

         (d)  For purposes only of this Section 2.4, the term "Subsidiary" 
shall not include Apsylog GmbH, a corporation organized under the laws of 
Germany.  Neither the Company nor Apsylog GmbH has engaged in any material 
business operations since its incorporation.  The only assets of the Company 
consist of shares of the capital stock of Apsylog.  Neither Apsylog GmbH nor 
the Company has any material liabilities, and Apyslog GmbH has no material 
assets.

    2.5  ACCOUNTS RECEIVABLE.  All accounts receivable shown on the Company 
Balance Sheet (net of reserves indicated on the Company Balance Sheet) or 
thereafter acquired until the Effective Time (net of reserves accrued in the 
normal course of business and consistent with past practice) arose and are 
collectible within 180 days from the date recorded, except that the value of 
any account receivable, the collection of which is doubtful or which is 
subject to a defense or set-off, has been written down to an amount not in 
excess of net realizable value or adequate reserves or allowances

                                       -13-
<PAGE>

therefor have been provided. The values at which accounts receivable are 
carried reflect the accounts receivable valuation policy of the Company, 
which is consistent with its past practice and in accordance with GAAP 
applied on a consistent basis.  None of the receivables of the Company or any 
Subsidiary is subject to any claim of offset, recoupment, set off, or 
counterclaim, and, to the knowledge of the Company, there are no facts or 
circumstances (whether asserted or unasserted) that would give rise to any 
claim.  No receivables are contingent upon the performance by the Company or 
any Subsidiary of any obligation or contract. No person or entity has any 
lien, charge, pledge, security interest, or other encumbrance on any such 
receivables, and no agreement for deduction or discount has been made with 
respect to any of such receivables.

such other date specifically set forth herein), except as otherwise

usual course and, without limiting the generality of the foregoing:

(whether or not covered by insurance) that would result in a Material Adverse
Effect on the Company or any Subsidiary.

         (b)  There have been no changes in the condition (financial or
otherwise), business, net worth, assets, properties, operations, obligations,
liabilities (fixed or contingent), or prospects of the Company or any Subsidiary
which, individually or in the aggregate, have resulted or may be reasonably
expected (whether before or after the Effective Time) to result in a Material
Adverse Effect on the Company or any Subsidiary.

         (c)  Neither the Company nor any Subsidiary has issued, or authorized
for issuance, any equity security, bond, note or other security, except for
shares of Company Common Stock issued upon the exercise of outstanding Company
Options, except for shares of Company Common Stock and Company Options listed in
Schedule 2.2, or accelerated the vesting of any employee stock benefits
(including vesting under stock purchase agreements or exercisability of Company
Options).  Neither the Company nor any Subsidiary has granted or entered into
any commitment or obligation to issue or sell any such equity security, bond,
note or other security of the Company or such Subsidiary, whether pursuant to
offers, stock option agreements, stock bonus agreements, stock purchase plans,
incentive compensation plans, warrants, calls, conversion rights or otherwise,
except for shares of Company Common issued upon the exercise of the Company

    2.7  TAX AND OTHER RETURNS AND REPORTS.
    
         (a)  DEFINITION OF TAXES.  For the purposes of this Agreement, "TAX"
or, collectively, "TAXES" means any and all federal, state, local, and foreign

profits, sales, use and occupation, and value added, ad valorem, transfer,
franchise, withholding, payroll, recapture, employment, excise and property
taxes, together with all interest, penalties and additions imposed with respect

decree binding upon the Company or any

                                       -18-
<PAGE>

Subsidiary of the Company which has or reasonably could be expected to have 
the effect of prohibiting or impairing any business practice of the Company 
or any Subsidiary, any acquisition of property (tangible or intangible) by 
the Company or any Subsidiary, or the conduct of business by the Company or 
any Subsidiary.  Without limiting the foregoing, neither the Company nor any 
Subsidiary has entered into any agreement under which the Company or any 
Subsidiary is restricted from selling, licensing or otherwise distributing 
any of its products to any class of customers, in any geographic area, during 
any period of time or in any segment of the market.
    
                                       
    2.9  TITLE TO PROPERTIES; ABSENCE OF LIENS AND ENCUMBRANCES; CONDITION OF
EQUIPMENT.
    
         (a)  Neither the Company nor any Subsidiary owns any real property, 
nor has the Company or any Subsidiary ever owned any real property. Schedule 
2.9(a) sets forth a list of all real property currently leased by the Company 
and the Subsidiaries, the name of the lessor, and the date of the lease and 
each amendment thereto.  All such current leases are in full force and 
effect, are valid and effective in accordance with their respective terms, 
and there is not, under any of such leases, any material existing default or 
event of default (or event which with notice or lapse of time, or both, would 
constitute a material default).  To the knowledge of the Company, neither its 
operations nor the operation of the Subsidiaries on any such real property, 
nor such real property, including improvements thereon, violate any 
applicable building code, zoning requirement, or classification, or pollution 
control ordinance or state relating to the particular property to such 
operations, and such non-violation is not dependent, in any instance, on 
so-called non-conforming use exceptions.
    
         (b)  The Company and the Subsidiaries have good and valid title to,
or, in the case of leased properties and assets, valid leasehold interests in,
all of their tangible properties and assets, real, personal and mixed, used or
held for use in their business, free and clear of any Liens, except as reflected
in the Company Financial Statements, except for liens created by the lessors of
such properties or assets, and except for Liens for Taxes not yet due and
payable and such imperfections of title and encumbrances, if any, which are not
material in character, amount or extent, and which do not materially detract
from the value, or materially interfere with the present use, of the property
subject thereto or affected thereby.

         (c)  All equipment owned or leased by the Company and the Subsidiaries
is listed in Schedule 2.9(c), except individual pieces of equipment owned by the
Company or a Subsidiary with an individual book value of less than $5,000.  All
facilities, machinery, equipment, fixtures, vehicles, and other properties
owned, leased, or used by the Company and the Subsidiaries are in good operating
condition, except for ordinary wear and tear, and repair and are reasonably fit
and usable for the purposes for which they are being used, except where a
failure to be in such condition would not have a Material Adverse Effect on the
Company or any Subsidiary.

    2.10 INTELLECTUAL PROPERTY.
    
         (a)  The Company or one of the Subsidiaries owns, or is validly
licensed to use, all patents, trademarks, trade names, service marks,
copyrights, and any applications therefor, maskworks, net lists, schematics,
technology, know-how, computer software programs or applications (in both source
code and object code form), and tangible or intangible proprietary information
or material that are used in the business of the Company and the Subsidiaries
(excluding Commercial Software Rights (as defined herein)) as currently
conducted or as proposed to be conducted (the "COMPANY INTELLECTUAL PROPERTY
RIGHTS").  Neither the Company nor any Subsidiary uses or is licensed to use,
and none of their products include or incorporate, any (i) software distributed
free of charge on a trial basis for which a paid license would be required for
commercial distribution, (ii) software whose ownership has been retained by a
third party who controls its distribution, or (iii) any other code obtained from
the public domain.
    
         (b)  Schedule 2.10(b) sets forth a complete list of all patents,
registered and material unregistered trademarks, registered and material
unregistered copyrights, trade names and service marks, and any applications
therefor, included in the Company Intellectual Property Rights, and specifies
the jurisdictions in which each such Company Intellectual Property Right has
been issued or registered or in which an application for such issuance and
registration has been filed, including the respective registration or
application numbers and the names of all registered owners, together with a list
of all software products currently marketed by the Company and the Subsidiaries
and an indication as to which, if any, of such software products have been
registered for copyright protection with the United States Copyright Office and
any foreign offices and by whom such items have been registered.

         (c)  Schedule 2.10(c) sets forth a complete list of (i) any requests
the Company or any Subsidiary has received to make any such registration,
including the identity of the requestor and the item requested to be so
registered and the jurisdiction for which such request has been made and (ii)
all licenses, sublicenses, and other agreements to which the Company or any
Subsidiary is a party and pursuant to which the Company, any Subsidiary, or any
other person is authorized to use any Company Intellectual Property Right or
trade secret material to the Company or any Subsidiary, and includes the
identity of all parties thereto, a description of the nature and subject matter
thereof, the applicable royalty, and the term thereof (other than standard
customer, distributor, and reseller software license agreements entered into by
the Company or any Subsidiary in the ordinary course of business).  The
execution and delivery of this Agreement by the Company, and the consummation of
the transactions contemplated hereby, will cause neither the Company nor any
Subsidiary to be in violation or default under any such license, sublicense or
agreement, nor entitle any other party to any such license, sublicense or
agreement to terminate or modify such license, sublicense or agreement.

         (d)  The Company or a Subsidiary is the sole and exclusive owner or
licensee of, with all right, title and interest in and to (free and clear of any
liens or encumbrances), the Company Intellectual Property Rights, and has sole
and exclusive rights (and is not contractually obligated to

                                       -20-
<PAGE>

pay any compensation to any third party in respect thereof) to the use 
thereof or the material covered thereby in connection with the services or 
products in respect of which the Company Intellectual Property Rights are 
being used.  No claims with respect to the Company Intellectual Property 
Rights have been asserted or, to the Company's knowledge, are threatened by 
any person, nor to the Company's knowledge are there any valid grounds for 
any bona fide claims (i) to the effect that the manufacture, sale, licensing 
or use of any of the products of the Company and the Subsidiaries infringes 
on any copyright, patent, trademark, service mark, trade secret or other 
proprietary right, (ii) against the use by the Company or any Subsidiary of 
any trademarks, service marks, trade names, trade secrets, copyrights, 
maskworks, patents, technology, know-how or computer software programs and 
applications used in the business of the Company and the Subsidiaries as 
currently conducted or as proposed to be conducted, or (iii) challenging the 
ownership by the Company or any Subsidiary, validity or effectiveness of any 
of the Company Intellectual Property Rights.  All registered trademarks, 
service marks and copyrights held by the Company and the Subsidiaries are 
valid and subsisting.  The business of the Company and the Subsidiaries as 
currently conducted or as proposed to be conducted has not and does not 
infringe on any proprietary right of any third party.  To the Company's 
knowledge, there is no unauthorized use, infringement or misappropriation of 
any of the Company Intellectual Property Rights by any third party, including 
any employee or former employee of the Company or any Subsidiary. 

         (e)  Neither the Company nor any Subsidiary has been sued or charged
as a defendant in any claim, suit, action, or proceeding which involves a claim
of infringement of any patents, trademarks, service marks, copyrights, or
violation of any trade secret or other proprietary right of any third party and
which has not been finally terminated prior to the date hereof nor does the
Company have any knowledge of any such charge or claim, and there is not any
infringement liability with respect to, or infringement or violation by, the

            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB
                                       
    Parent and Merger Sub represent and warrant to the Company as follows:
    
    3.1   ORGANIZATION OF PARENT AND MERGER SUB.  Parent is a corporation 
duly organized, validly existing, and in good standing under the laws of the 
State of Delaware.  Merger Sub is a corporation duly organized, validly 
existing, and in good standing under the laws of the State of Delaware.  Each 
of Parent and Merger Sub has the corporate power to own its properties and to 
carry on its business as now being conducted and is duly qualified to do 
business and is in good standing in each jurisdiction in which the failure to 
be so qualified would have a material adverse effect on the ability of Parent 
and Merger Sub to consummate the transactions contemplated hereby.
    
    3.2   AUTHORITY.  Parent and Merger Sub have all requisite corporate 
power and authority to enter into this Agreement and to consummate the 
transactions contemplated hereby.  The execution and delivery of this 
Agreement and the consummation of the transactions contemplated hereby have 
been duly authorized by all necessary corporate action on the part of Parent 
and Merger Sub.  This Agreement has been duly executed and delivered by 
Parent and Merger Sub and constitutes the valid and binding obligation of 
Parent and Merger Sub, enforceable in accordance with its terms.  The 
execution and delivery of this Agreement does not, and the consummation of 
the transactions contemplated hereby and thereby will not, conflict with, or 
result in any violation of, or default (with or without notice or lapse of 
time, or both), or give rise to a right of termination, cancellation or 
acceleration of any obligation or to loss of a benefit under any provision of 
the Certificate of Incorporation or Bylaws of Parent or Merger Sub or (ii) 
any mortgage, indenture, lease, contract or other agreement or instrument, 
permit, concession, franchise, license, judgment, order, decree, statute, 
law, ordinance, rule or representation applicable to Parent or on which 
Parent's business, financial condition, operations or prospects is 
substantially dependent, the breach, violation, default, termination or 
forfeiture of which would result in a material adverse effect upon the 
ability of Parent 

                                     -31-
<PAGE>

or Merger Sub to consummate the Merger, or a Material Adverse Effect on 
Parent or Merger Sub.  No consent, approval, order or authorization of, or 
registration, declaration or filing with, any Governmental Entity, is 
required by or with respect to Parent or Merger Sub in connection with the 
execution and delivery of this Agreement by Parent and Merger Sub or the 
consummation by Parent and Merger Sub of the transactions contemplated hereby 
except for (i) the filing of the Certificate of Merger with the Secretary of 
State of the State of Delaware or (ii) such consents, approvals, order, 
authorizations, registrations, declarations and filings as may be required 
under applicable state and federal securities laws.
    
    3.3   PARENT COMMON STOCK.  The shares of Parent Common Stock to be 
issued pursuant to the Merger will, when issued and delivered in accordance 
with this Agreement, be duly authorized, validly issued, fully paid, and 
non-assessable; PROVIDED, HOWEVER, that the Parent Common Stock to be issued 
hereunder will be subject to restrictions on transfer under applicable 
federal and state securities laws.
    
    3.4   SEC DOCUMENTS; PARENT FINANCIAL STATEMENTS.  Parent has filed all 
forms, reports, and documents required to be filed by Parent with the United 
States Securities and Exchange Commission (the "SEC") and has furnished or 
made available to the Company true and complete copies of its Annual Report 
on Form 10-K for the fiscal year ended March 31, 1997 and its Quarterly 
Report on Form 10-Q for the quarter ended June 30, 1997 (collectively, the 
"SEC DOCUMENTS"), which Parent filed with the SEC under the United States 
Securities Exchange Act of 1934 (the "EXCHANGE ACT").  As of their respective 
filing dates, the SEC Documents complied in all material respects with the 
requirements of the Exchange Act, and none of the SEC Documents contained any 
untrue statement of a material fact or omitted to state a material fact 
required to be stated therein or necessary to make the statements made 
therein, in light of the circumstances in which they were made, not 
misleading, except to the extent corrected by a document subsequently filed 
with the SEC.  The consolidated financial statements of Parent, including the 
notes thereto, included in the SEC Documents (the "PARENT FINANCIAL 
STATEMENTS") comply as to form in all material respects with applicable 
accounting requirements and with the published rules and regulations of the 
SEC with respect thereto, have been prepared in accordance with United States 
GAAP consistently applied (except as may be indicated in the notes thereto 
or, in the case of unaudited statements, as permitted by Form 10-Q of the 
SEC), and fairly present the consolidated financial position of Parent and 
the results of its operations and cash flows as of  the respective dates and 
for the periods indicated therein (subject, in the case of unaudited 
statements, to normal audit adjustments).  There has been no change in 
Parent's accounting policies except as described in the notes to the Parent 
Financial Statements.
    
    3.5   NO MATERIAL ADVERSE CHANGE.  Since June 30, 1997, Parent has 
conducted its business in the ordinary course and there has not occurred:  
(a) any material adverse change in the financial condition, results of 
operations, liabilities, assets (including intangible assets), business, or 
prospects of Parent and its subsidiaries, taken as a whole; (b) any amendment 
or change in the Certificate of Incorporation or Bylaws of Parent; or (c) any 
damage to, destruction or loss of any assets of the 

                                     -32-
<PAGE>

Parent (whether or not covered by insurance) that materially and adversely 
affects the financial condition or business of Parent and its subsidiaries, 
taken as a whole.

    3.6   LITIGATION.  There is no action, suit or proceeding of any nature 
pending or to Parent's knowledge threatened against Parent, nor, to the 
knowledge of Parent, is there any reasonable basis therefor which could 
reasonably be expected to result in a Material Adverse Effect on Parent.  

    3.7   BROKERS' AND FINDERS' FEES.  Parent has not incurred, nor will it 
incur, directly or indirectly, any liability for brokerage or finders' fees 
or agents' commissions or any similar charges in connection with this 
Agreement or any transaction contemplated hereby. 

    3.8   SECURITIES ACT EXEMPTION.  Subject to the accuracy of

representations, warranties, certifications, and additional information as 
Parent may reasonably request to ensure the availability of an exemption from 
the registration requirements of the Securities Act.

applicable state securities laws or by any contract which continues in effect

with Parent=s transfer agent), stating substantially as follows:

                                     -33-
<PAGE>

         COMMISSION. 

    4.3  STOCKHOLDERS' REPRESENTATIONS REGARDING SECURITIES LAW MATTERS. Each 
stockholder of the Company, by virtue of the Merger and the conversion into 
Parent Common Stock of the Company Capital Stock held by such stockholder, 
shall be bound by the following provisions:
    
         (a)  Such stockholder will not offer, sell, or otherwise dispose of 
any shares of Parent Common Stock except in compliance with the Securities 
Act and the rules and regulations thereunder.
    
         (b)  Such stockholder will not sell, transfer or otherwise dispose 
of any shares of Parent Common Stock unless (i) such sale, transfer or other 
disposition is within the limitations of and in compliance with Rule 144 or 
Rule 145, as applicable, promulgated by the SEC under the Securities Act and 
the Stockholder furnishes Parent with reasonable proof of compliance with 
such Rule, (ii) in the opinion of counsel, reasonably satisfactory to Parent 
and its counsel, some other exemption from registration under the Securities 
Act is available with respect to any such proposed sale, transfer, or other

Common Stock is registered under the Securities Act.
    
    4.4  REGISTRATION RIGHTS.

         (a)  Parent agrees that the stockholders of the Company receiving 
Parent Common Stock in the Merger shall be entitled to the registration 
rights set forth in the Declaration of Registration Rights of even date 
herewith in the form attached hereto as EXHIBIT B.

         (b)  On or before the 45th day after the Effective Time, Parent will 
determine whether to  proceed with an Underwritten Sale (as defined in

holders of the Registrable Securities (as defined in the Declaration of 
Registration Rights) to include Registrable Securities in a registration in 
accordance

6.1 of this Agreement, the Company will request, and the stockholders will be 
required to state in writing the number of shares of Registrable Securities 
which they request Parent to cause to be registered in accordance with the 
provisions of the Declaration of Registration Rights. The failure of any 
Company stockholder to make such request shall be deemed to be a statement of 
no intent by such stockholder to include any Registrable Securities in such 
registration.

    6.15 COMPANY CAPITAL STRUCTURE; SUBSIDIARIES.

         (a)   The Company shall (i) use its best efforts  to cause holders 
of the outstanding call option set forth in the Option Purchase Agreement 
dated April 16, 1997 between the Company and certain shareholders of Apsylog 
SA, a corporation organized under the laws of the Republic of France 
("Apsylog"), to exercise such option or (ii) exercise the put option held by 
the Company as set forth in the Put Agreement dated April 16, 1997 between 
the Company and such purchasers, in either case such that immediately after 
such exercises and prior to the Closing, (A) the Company will hold all the 
outstanding share capital of Apsylog (other than director's qualifying shares 
and 68,000 shares held of record by Philippe Haustete (the "Apsylog Minority 
Holder")) and (B) no further right to acquire or obligation to issue shares 
of Company Capital Stock shall be outstanding (other than the Company Options 
and the conversion rights of the Company Preferred Stock).

         (b)  On or before thirty (30) days following the  Effective Time, 
Parent and the Participating Stockholders (as defined herein) shall enter 
into an agreement or agreements as necessary to provide for the sale (the 
"Stock Sale") by Parent to the Participating Stockholders of all of the 
outstanding shares held by Apsylog SA, a French corporation ("Apsylog"), in 
each of APSYNet, a French corporation ("A-Net"), and Netform, a French 
corporation ("Net", and collectively with A-Net, the "Subs").  Such agreement 
or agreements shall provide for the Stock Sale on substantially the following 
terms:

              (i)   The Securityholder Agent (as defined in Article VIII) 
shall, promptly following the Effective Time, notify in writing each holder 
of record of the Certificates (as defined in Section 1.8(c) above) of the 
principal terms set forth in this Section 6.15(b) of the opportunity to 
participate in the Stock Sale, pro rata in the proportion of the shares of 
Company Common Stock represented by the Certificates held by such holder 
bears to the total shares of all of the outstanding Company Common Stock 
outstanding immediately prior to the Effective Time (including any shares in 
Apsylog which may have then been held by the Apsylog Minority Stockholder) 
AND which elect to participate in the Stock Sale.  The Participating 
Stockholders shall at a minimum include those stockholders identified in 
Schedule 6.15 attached hereto, each of whom shall be required to agree to the 
terms of this Section 6.15(b) concurrently with the execution of this 
Agreement as an inducement to Parent to enter into this Agreement.  

              (ii)  Each such holder who elects to participate in the Stock Sale
(the "Participating Stockholders") shall, jointly with all Participating
Stockholders, purchase all of the outstanding shares of the Subs held by Apsylog
for aggregate consideration equal to $500,000, payable either by cash or through
promissory notes duly executed and delivered by the Participating Stockholders
(the "Notes").  The Notes may be prepaid at any time, and shall bear minimal
interest 

                                      48

<PAGE>

(as necessary to avoid the imputation of interest), mature as to principal 
and interest 180 days following their issue date, and be secured by Parent 
Common Stock issued in connection with the Merger (but not included as part 
of the Escrow Fund) having a fair market value equal to not less 120% of the 
principal amount of the Notes on the issue date.  The shares of Parent Common 
Stock securing the Notes shall be held in an escrow (independent of the 
Escrow Fund) by Parent.  Upon the sale of any shares of Parent Common Stock 
held by a Participating Stockholder (whether or not such shares may 
constitute collateral for a Note), the Participating Stockholder will be 
obligated to remit to Parent the proceeds of such sale as necessary to repay 
all principal and interest under the Note, with any excess proceeds to be 
retained by the Participating Stockholder.  Any sales or transfer taxes 
resulting from the Stock Sale shall be paid by the Participating Stockholders.

              (iii) Parent agrees that pending the completion of the 
Stock Sale, Parent will (except to the extent that the Securityholder Agent 
otherwise agrees in writing) conduct the business of the Subs in the usual, 
regular and ordinary course in substantially the same manner as heretofore 
conducted. Subject to the foregoing, Parent shall have no responsibility or 
obligation to any Participating Stockholder or any other holder of Company 
Common Stock outstanding immediately prior to the Effective Time for any 
adverse event, condition or circumstance that may occur in connection with 
the conduct of the business of the Subs or the condition of the business or 
operations of the Subs, and Parent shall not be obligated to provide any 
representation or warranty to the Participating Stockholders concerning such 
conduct in connection with the Stock Sale.  Upon completion of the Stock 
Sale, none of Parent, the Company nor any Subsidiary shall have any liability 
or obligation to the Subs or to any stockholder, purchaser, creditor, 
employee, vendor or customer of either Sub or of Parent, the Company or any 
Subsidiary, and the Participating Stockholders will agree to indemnify Parent 
and its affiliates against any claims alleging such liability or obligation.

         (c)   The Company and Parent shall use their best efforts to cause the
Apsylog Minority Holder, prior to the Closing, to convert his equity interest in
Apsylog into shares of Company Capital Stock on the same terms and conditions as
set forth in the Series A and Series B Preferred Stock Purchase Agreement dated
April 16, 1997 among the Company and certain prior holders of Apsylog's capital
stock.

    6.16 TERMINATION OF UNITED KINGDOM DISTRIBUTORSHIP.  Prior to the Closing,
the Company shall provide written notice to Apsylog (UK) Ltd., a corporation
organized under the laws of England (the "Distributor"), advising of the
Company's intent to terminate the exclusivity provisions of its International
Master Reseller Agreement with the Distributor dated as of July 19, 1996 (the
"Distribution Agreement"), and following the Effective Time, the Company and
Gilles Queru on behalf of the Company Stockholders (as defined in Article VIII)
shall use their best and lawful efforts (which shall not be construed to require
any monetary payment to Distributor) to terminate such exclusivity provisions
(which may be accomplished by terminating the Distribution Agreement in its
entirety)  in consultation with, and in a manner reasonably acceptable to,
Parent. Neither of the Company, Gilles Queru, or any Company Stockholder shall
have any liability to Parent under the provisions of Article VIII in the event
that the Distributor cures any default under the Distribution 

                                      49

<PAGE>

Agreement in accordance with its terms, or in the event that the 
Securityholder Agent is unable to lawfully terminate the exclusivity 
provisions of the Distribution Agreement.

    6.17 COMPLETION OF AUDIT.  The Company shall use its best efforts to assist
Coopers & Lybrand LLP to complete its audit of the Company Financial Statements
prior to the Closing.

    6.18 FILING OF TAX RETURNS; PAYMENT OF TAXES. Prior to the Closing, the
Company shall accurately complete its United States federal and California state
tax returns for the fiscal year ended December 31, 1996 and pay any amounts
indicated thereon as being due.

    6.19 EMPLOYMENT AGREEMENTS.  Prior to the Closing, Parent (or a Subsidiary,
as appropriate) and each of Gilles Queru, Nicholas Bourveau, and Stephane
Dehoche shall enter into amendments to their respective employment agreements
with Apsylog, and Daniel Callahan and the Company shall have entered into an
agreement terminating the offer letter dated March 22, 1996 between Apsylog, a
California corporation, and Mr. Callahan (collectively, the "EMPLOYMENT
AGREEMENTS").

    6.20 NO SOLICITATION.  From and after the date of this Agreement until 
the earlier to occur of the Effective Time or termination of this Agreement 
pursuant to its terms, neither the Company, any Subsidiary, or any Affiliate 
Stockholder will, and the Company, the Subsidiaries, and the Affiliate 
Stockholders will instruct their respective directors, officers, employees, 
representatives, investment bankers, agents, and affiliates not to, directly 
or indirectly (i) solicit or encourage submission of any Acquisition Proposal 
(as defined herein) by any person, entity, or group (other than Parent and 
its affiliates, agents, and representatives) or (ii) participate in any 
discussions or negotiations with, or disclose any non-public information 
concerning the Company or any Subsidiary to, or afford access to the 
properties, books, or records of the Company or any Subsidiary to, or 
otherwise assist or facilitate, or enter into any agreement or understanding 
with, any person, entity, or group (other than Parent and its affiliates, 
agents, and representatives) in connection with any Acquisition Proposal with 
respect to the Company or any Subsidiary.  For purposes of this Agreement, an 
"Acquisition Proposal" means any proposal or offer relating to (i) any 
merger, consolidation, sale or license of substantial assets or similar 
transactions involving the Company or any Subsidiary (other than sales or 
licenses of assets or inventory in the ordinary course of business or as 
permitted by this Agreement) or (ii) sales by the Company or any Subsidiary 
of any shares of its capital stock (including, without limitation, by way of 
a tender offer or an exchange offer and except as contemplated pursuant to 
Section 6.15 and upon exercise of Company Options).  The Company, the 
Subsidiaries, and the Affiliate Stockholders will immediately cease any and 
all existing activities, discussion, or negotiations with any parties 
conducted heretofore with respect to any of the foregoing.  The Company and 
the Affiliate Stockholders will promptly (i) notify Parent if it receives any 
proposal or written inquiry or written request for information in connection 
with an Acquisition Proposal or potential Acquisition Proposal and (ii) 
notify Parent of the significant terms and conditions of any such Acquisition 
Proposal.  In addition, from and after the date of this Agreement, until the 
earlier to occur of the Effective Time or termination of this Agreement 
pursuant to its terms, the Company, the Subsidiaries, and the Affiliate 
Stockholders will not, and will instruct their 

                                      50

<PAGE>

respective directors, officers, employees, representatives, investment 
bankers, agents, and affiliates not to, directly or indirectly, make or 
authorize any public statement, recommendation, or solicitation in support of 
any Acquisition Proposal made by any person, entity, or group (other than 
Parent).

has delivered to Parent, concurrently with the execution of this Agreement, 
an executed Indemnity Agreement in the form attached hereto as EXHIBIT F (the 
"INDEMNITY AGREEMENTS").

    6.22 BENEFIT ARRANGEMENTS.  Parent covenants and agrees that to the 
extent permitted by applicable law and to the extent the existing benefit 
plans and arrangements provided by Company and any Subsidiary to its 
employees are terminated on or after the Effective Time, such employees shall 
be entitled to comparable benefits which are available or subsequently become 
available to Parent's employees in the country of employment.  For purposes 
of satisfying the terms and conditions of such plans, Parent shall give full 
credit for eligibility, vesting or benefit accrual for each participant's 
period of service at the Company or any Subsidiary prior to the Effective 
Time. 

    6.23 REORGANIZATION.  No party to the Agreement shall take any action, 
either prior to or subsequent to the Closing, that would cause the Merger to 
fail to qualify as a "reorganization" under Section 368(a) of the code, and 
each party agrees to file all Returns consistent with such treatment.

its affiliates (including the Surviving Corporation) for any claims, losses, 
liabilities, damages, deficiencies, costs and expenses, including reasonable 
attorneys= fees and expenses and expenses of investigation and defense 
incurred by Parent, its officers, directors or affiliates (including the 
Surviving Corporation) (i) directly or indirectly as a result of any 
inaccuracy or breach of a representation or warranty of the Company or of any 
Affiliate Stockholder contained herein, or in any certificate, instrument, 
schedule or document delivered by the Company or any Affiliate Stockholder at 
the Closing in connection with this Agreement or the Merger, or any failure 
by the Company or any Affiliate Stockholder prior to the Closing to perform 
or comply with any covenant contained herein or (ii) in the event the Company 
prior to the Closing, or the Securityholder Agent after the Closing, agrees 
to any cash settlement with the Distributor for the purposes of terminating 
the exclusivity provisions of the Distribution Agreement as provided in 
Section 6.16 above (hereinafter individually a ALOSS@ and collectively 
"LOSSES"), provided that claims arising out of an inaccuracy or breach of any 
representations and warranties and any covenant of the Company or the 
Affiliate Stockholders contained in this Agreement and in any certificate, 
instrument, schedule or document delivered by the Company or the Affiliate 
Stockholders at the Closing in connection with this Agreement or the Merger 
must be asserted on or before 5:00 p.m. (California Time) on the date that is 
one year following the Closing Date and provided further, that a Loss for 
purposes of clause (ii) above shall be deemed to include only the amount of 
such cash settlement, exclusive of any expenses or costs incurred in 
attorneys' fees or other expenses or costs incidental to such cash 
settlement.  No portion of the Escrow Amount shall be contributed in respect 
of any Company Options.  Except as provided in Section 11.2 relating to Third 
Party Expenses (as defined therein) exceeding $150,000, which excess shall be 
payable from the Escrow Fund, Parent may not receive any shares from the 
Escrow Fund unless and until Officer=s Certificates (as defined in paragraph 
(d) below) identifying Losses, the aggregate amount of which exceed $75,000 
(of which no individual

                                       49

<PAGE>

Loss shall be less than $5,000), have been delivered to the Escrow Agent as 
provided in paragraph (d) and either there is no objection thereto or any 
objection has been resolved in accordance with the provisions of this Article 
VIII; in such case, Parent may recover from the Escrow Fund all Losses 
(including any Losses within the $75,000 threshold and any individual Losses 
that may be less than $5,000) for which there is no objection or any 
objection had been resolved in accordance with the provisions of this Article 
VIII in accordance with the provisions of this Section 8.2.

         (b)  ESCROW PERIOD; DISTRIBUTION UPON TERMINATION OF ESCROW PERIOD. 
Subject to the following requirements, the Escrow Fund shall be in existence 
immediately following the Effective Time and shall terminate at 5:00 p.m. 
(California Time) on the date that is one year following the Closing Date, 
both such dates to be certified to the Escrow Agent in an Officer's 
Certificate (the "ESCROW PERIOD").  Such amount (or some portion thereof) 
that is necessary in the reasonable judgment of Parent, subject to the 
objection of the Securityholder Agent and the subsequent arbitration of the 
matter in the manner provided in Section 8.2(f) hereof, to satisfy any 
unsatisfied claims concerning facts and circumstances existing prior to the 
termination of such Escrow Period as are specified in any Officer's 
Certificate delivered to the Escrow Agent prior to termination of such Escrow 
Period, may be retained in the Escrow Fund after termination of the Escrow 
Period.  As soon as any or all such claims have been resolved as evidenced by 
the written memorandum of the Securityholder Agent and Parent, the Escrow 
Agent shall deliver to the Company Stockholders the remaining portion of the 
Escrow Fund that is not required to satisfy such claims.  If no Officer's 
Certificate pertaining to unsatisfied claims is delivered to the Escrow Agent 
prior to the termination of the Escrow Period, upon termination of the Escrow 
Period, the Escrow Agent, without further authorization or instruction, shall 
distribute the remainder of the Escrow Fund to the Company Stockholders in 
accordance with the provisions of this Section 8.2(b).  Deliveries of Escrow 
Amounts to the Company Stockholders pursuant to this Section 8.2(b) shall be 
made in proportion to their respective original contributions to the Escrow 
Fund (as set forth on EXHIBIT K attached hereto).

         (c)  PROTECTION OF ESCROW FUND.  

              (i)  The Escrow Agent shall hold and safeguard the Escrow Fund 
during the Escrow Period, shall treat such fund as a trust fund in accordance 
with the terms of this Agreement and not as the property of Parent and shall 
hold and dispose of the Escrow Fund only in accordance with the terms hereof.

              (ii) Any shares of Parent Common Stock or other equity 
securities issued or distributed by Parent (including shares issued upon a 
stock dividend or split) ("NEW SHARES") in respect of Parent Common Stock in 
the Escrow Fund which have not been released from the Escrow Fund shall be 
deposited with the Escrow Agent and added to the Escrow Fund and become a 
part thereof.  New Shares issued in respect of shares of Parent Common Stock 
which have been released from the Escrow Fund shall not be added to the 
Escrow Fund but shall be distributed to the recordholders thereof.  Cash 
dividends on Parent Common Stock held in the Escrow Fund shall not be added 
to the Escrow Fund but shall be distributed to the recordholders thereof.

                                       50

<PAGE>

              (iii)     Each Company Stockholder shall have voting rights 
with respect to the shares of Parent Common Stock contributed to the Escrow 
Fund by such Company Stockholder (and on any voting securities and other 
dividends added to the Escrow Fund in respect of such shares of Parent Common 
Stock).

         (d)  CLAIMS UPON ESCROW FUND. 

              (i)  Upon receipt by the Escrow Agent at any time on or before 
the last day of the Escrow Period of a certificate signed by any officer of 
Parent (an "OFFICER'S CERTIFICATE"): (A) stating that Parent has paid or 
properly accrued or reasonably anticipates that it will have to pay or accrue 
Losses, and (B) specifying in reasonable detail the individual items of 
Losses included in the amount so stated, the date each such item was paid or 
properly accrued, or the basis for such anticipated liability, and the nature 
of the misrepresentation, breach of warranty or covenant to which such item 
is related, the Escrow Agent shall, subject to the provisions of Section 
8.2(e) hereof, deliver to Parent out of the Escrow Fund, as promptly as 
practicable, shares of Parent Common Stock held in the Escrow Fund in an 
amount equal to such Losses.

              (ii) For the purposes of determining the number of shares of 
Parent Common Stock to be delivered to Parent out of the Escrow Fund pursuant 
to Section 8.2(d)(i) hereof, the shares of Parent Common Stock shall be 
valued at a price of $15.25 per share (the "Parent Price Per Share").

         (e)  OBJECTIONS TO CLAIMS.  At the time of delivery of any Officer's 
Certificate to the Escrow Agent, a duplicate copy of such certificate shall 
be delivered to the Securityholder Agent and for a period of thirty (30) days 
after receipt of such Officer's Certificate, the Escrow Agent shall make no 
delivery to Parent of any Escrow Amounts pursuant to Section 8.2(d) hereof 
unless the Escrow Agent shall have received written authorization from the 
Securityholder Agent to make such delivery.  After the expiration of such 
thirty (30) day period, the Escrow Agent shall make delivery of shares of 
Parent Common Stock from the Escrow Fund in accordance with Section 8.2(d) 
hereof, provided that no such payment or delivery may be made if the 
Securityholder Agent shall object in a written statement to the claim made in 
the Officer's Certificate, and such statement shall have been delivered to 
the Escrow Agent prior to the expiration of such thirty (30) day period.

         (f)  RESOLUTION OF CONFLICTS; ARBITRATION.

                   (i)  In case the Securityholder Agent shall so object in 
writing to any claim or claims made in any Officer's Certificate, the 
Securityholder Agent and Parent shall attempt in good faith to agree upon the 
rights of the respective parties with respect to each of such claims.  If the 
Securityholder Agent and Parent should so agree, a memorandum setting forth 
such agreement shall be prepared and signed by both parties and shall be 
furnished to the Escrow Agent.  The Escrow Agent shall be entitled to rely on 
any such memorandum and distribute shares of Parent Common Stock from the 
Escrow Fund in accordance with the terms thereof.

                                       51

<PAGE>

                   (ii)  If no such agreement can be reached after good faith 
negotiation, either Parent or the Securityholder Agent may demand arbitration 
of the matter unless the amount of the damage or loss is at issue in pending 
litigation with a third party, in which event arbitration shall not be 
commenced until such amount is ascertained or both parties agree to 
arbitration; and in either such event the matter shall be settled by 
arbitration conducted by three arbitrators.  Parent and the Securityholder 
Agent shall each select one arbitrator, and the two arbitrators so selected 
shall select a third arbitrator, each of which arbitrators shall be 
independent and have at least ten years relevant experience.  The arbitrators 
shall set a limited time period and establish procedures designed to reduce 
the cost and time for discovery while allowing the parties an opportunity, 
adequate in the sole judgment of the arbitrators, to discover relevant 
information from the opposing parties about the subject matter of the 
dispute.  The arbitrators shall rule upon motions to compel or limit 
discovery and shall have the authority to impose sanctions, including 
attorneys fees and costs, to the same extent as a court of competent law or 
equity, should the arbitrators determine that discovery was sought without 
substantial justification or that discovery was refused or objected to 
without substantial justification.  The decision of a majority of the three 
arbitrators as to the validity and amount of any claim in such Officer's 
Certificate shall be binding and conclusive upon the parties to this 
Agreement, and notwithstanding anything in Section 8.2(e) hereof, the Escrow 
Agent shall be entitled to act in accordance with such decision and make or 
withhold payments out of the Escrow Fund 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.

                   (iii) Any such arbitration shall be held in San Diego 
County, California and shall be conducted by, and under the rules then in 
effect, of the Judicial Arbitration and Mediation Services, Inc.  For 
purposes of this Section 8.2(f), in any arbitration hereunder in which any 
claim or the amount is at issue, Parent shall be deemed to be the 
Non-Prevailing Party in the event that the arbitrators award Parent less than 
the sum of one-half (1/2) of the disputed amount plus any amounts not in 
dispute; otherwise, the Company Stockholders as represented by the 
Securityholder Agent shall be deemed to be the Non-Prevailing Party.  The 
Non-Prevailing Party to an arbitration shall pay its own expenses, the fees 
of each arbitrator, the administrative costs of the arbitration, and the 
expenses, including without limitation, reasonable attorneys' fees and costs, 
incurred by the other party to the arbitration. Judgment upon any award 
rendered by the arbitrators may be entered in any court having jurisdiction.  
The Securityholder Agent may pay such amounts contemplated under this Section 
8.2(f)(iii) and Section 8.2(i)(ii) or other amounts contemplated in this 
Section 8.2 (including without limitation unreimbursed expenses of counsel 
for the Company Stockholders and Parent, arbitrator fees and administrative 
costs) by distributing shares of Parent Common Stock from the Escrow Fund 
with respect to which Parent has not made a claim; PROVIDED, HOWEVER, that no 
shares of Parent Common Stock may be distributed from the Escrow Fund prior 
to the termination of the Escrow Period and such shares may be distributed 
only to the extent that such shares are not required to satisfy any claim for 
Losses.

         (g)  SECURITYHOLDER AGENT OF THE COMPANY STOCKHOLDERS; POWER OF
ATTORNEY.
    
              (i)  In the event that the Merger is approved, effective upon 
such vote, and without further act of any Company Stockholder, Vincent Worms 
shall be appointed as agent and attorney-in-fact (the "SECURITYHOLDER AGENT") 
for each Company Stockholder (except such Company Stockholders, if any, as 
shall have perfected their appraisal rights under Delaware Law), for and on 
behalf of Company Stockholders, to give and receive notices and 
communications, to authorize delivery to Parent of shares of Parent Common 
Stock from the Escrow Fund in satisfaction of claims by Parent, 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 Securityholder Agent for the 
accomplishment of the foregoing.  Such agency may be changed by the Company 
Stockholders from time to time upon not less than thirty (30) days prior 
written notice to Parent and Escrow Agent; provided that the Securityholder 
Agent may not be removed unless holders of a two-thirds interest of the 
Escrow Fund agree to such removal and to the identity of the substituted 
agent.  Any vacancy in the position of Securityholder Agent may be filled by 
approval of the holders of a majority in interest of the Escrow Fund. No bond 
shall be required of the Securityholder Agent, and the Securityholder Agent 
shall not receive compensation for his or her services.  Notices or 
communications to or from the Securityholder Agent shall constitute notice to 
or from each of the Company Stockholders.

              (ii) The Securityholder Agent shall not be liable for any act 
done or omitted hereunder as Securityholder Agent while acting in good faith 
and in a manner that is not grossly negligent. 

         (h)  ACTIONS OF THE SECURITYHOLDER AGENT.  A decision, act, consent 
or instruction of the Securityholder Agent shall constitute a decision of all 
the Company Stockholders for whom a portion of the Escrow Amount otherwise 
issuable to them is deposited in the Escrow Fund and shall be final, binding 
and conclusive upon each of such Company Stockholders, and the Escrow Agent 
and Parent may rely upon any such decision, act, consent or instruction of 
the Securityholder Agent as being the decision, act, consent or instruction 
of each and every such Company Stockholder of the Company.  The Escrow Agent 
and Parent are hereby relieved from any liability to any person for any acts 
done by them in accordance with such decision, act, consent or instruction of 
the Securityholder Agent.  The Company Stockholders agree jointly and 
severally to indemnify and hold the Securityholder Agent harmless against any 
and all losses, claims, damages, liabilities, and expenses, including 
reasonable costs of investigation, counsel fees, and disbursements that may 
be imposed on Securityholder Agent or incurred by him on behalf of the 
Company Stockholders in the connection with his actions taken under this 
Agreement, including without limitation expenses incurred as contemplated by 
Sections 8.2(f)(iii) and 8.2(i)(ii).  

         (i)  THIRD-PARTY CLAIMS. (i) If any third party shall notify Parent 
or its affiliates hereto with respect to any matter (hereinafter referred to 
as a "Third Party Claim"), which may give rise to a claim by Parent against 
the Escrow Fund, then Parent shall give notice to the Securityholder

                                       53

<PAGE>

Agent within 30 days of Parent becoming aware of any such Third Party Claim 
or of facts upon which any such Third Party Claim will be based setting forth 
such material information with respect to the Third party Claim as is 
reasonably available to Parent; PROVIDED, HOWEVER, that no delay or failure 
on the part of Parent in notifying the Securityholder Agent shall relieve the 
Securityholder Agent and the Company Stockholders from any obligation 
hereunder unless the Securityholder Agent and the Company Stockholders are 
thereby materially prejudiced (and then solely to the extent of such 
prejudice).  The Securityholder Agent and the Company Stockholders shall not 
be liable for any attorneys fees and expenses incurred by Parent prior to 
Parent's giving notice to the Securityholder Agent of a Third Party Claim.  
The notice from Parent to the Securityholder Agent shall set forth such 
material information with respect to the Third Party Claim as is then 
reasonably available to Parent. 

              (ii) In case any Third Party Claim is asserted against Parent 
or its affiliates, and Parent notifies the Securityholder Agent thereof 
pursuant to Section 8.2(i)(a) hereinabove, the Securityholder Agent and the 
Company Stockholders will be entitled, if the Securityholder Agent so elects 
by written notice delivered to Parent within 30 days after receiving Parent's 
notice, to assume the defense thereof, at the expense of the Company 
Stockholders independent of the Escrow Fund, with counsel reasonably 
satisfactory to Parent so long as: 

                   a)   Parent has reasonably determined that Losses which 
may be incurred as a result of the Third Party Claim do not exceed either 
individually, or when aggregated with all other Third Party Claims, the total 
dollar value of the Escrow Fund determined in accordance with Section 
8.2(d)(ii) hereof; 

                   b)   the Third Party Claim involves only money damages and 
does not seek an injunction or other equitable relief; 

                   c)   settlement of, or an adverse judgment with respect 
to, the Third Party Claim is not, in the good faith judgment of Parent, 
likely to establish a precedential custom or practice adverse to the 
continuing business interests of Parent which could have a material adverse 
effect on the business or operations of Parent; and 

                   d)   counsel selected by the Securityholder Agent is 
reasonably acceptable to Parent.

    If the Securityholder Agent and the Company Stockholders so assume any 
such defense, the Securityholder Agent and the Company Stockholders shall 
conduct the defense of the Third Party Claim actively and diligently.  The 
Securityholder Agent and the Company Stockholders shall not compromise or 
settle such Third Party Claim or consent to entry of any judgment in respect 
thereof without the prior written consent of Parent and/or its affiliates, as 
applicable.  

              (iii)     In the event that the Securityholder Agent assumes 
the defense of the Third Party Claim in accordance with Section 8.2(i)(ii) 
above, Parent or its affiliates may retain 

                                       54
<PAGE>

separate counsel and participate in the defense of the Third Party Claim, but 
the fees and expenses of such counsel shall be at the expense of Parent 
unless Parent or its affiliates shall reasonably determine that there is a 
material conflict of interest between or among Parent or its affiliates and 
the Securityholder Agent and the Company Stockholders with respect to such 
Third Party Claim, in which case the reasonable fees and expenses of such 
counsel will be borne by the Securityholder Agent and the Company 
Stockholders out of the Escrow Fund.  Parent or its affiliates will not 
consent to the entry of any judgment or enter into any settlement with 
respect to the Third Party Claim without the prior written consent of the 
Securityholder Agent.  Parent will cooperate in the defense of the Third 
Party Claim and will provide full access to documents, assets, properties, 
books and records reasonably requested by Securityholder Agent and material 
to the claim and will make available all officers, directors and employees 
reasonably requested by Securityholder Agent for investigation, depositions 
and trial. 

          (iv) In the event that the Securityholder Agent fails or elects not 
to assume the defense of Parent or its affiliates against such Third Party 
Claim, which Securityholder Agent had the right to assume under Section 
8.2(i)(ii) above, a) Parent or its affiliates shall have the right to 
undertake the defense and b) Parent shall not compromise or settle such Third 
Party Claim or consent to entry of any judgment in respect thereof without 
the prior written consent of Securityholder Agent.  In the event that the 
Securityholder Agent is not entitled to assume the defense of Parent or its 
affiliates against such Third Party Claim pursuant to Section 8.2(i)(ii) 
above, Parent or its affiliates shall have the right to undertake the 
defense, consent to the entry of any judgment or enter into any settlement 
with respect to the Third Party Claim in any manner it may deem appropriate 
(and Parent or its affiliates need not consult with, or obtain any consent 
from, the Securityholder Agent or the Company Stockholders in connection 
therewith); provided, however, that except with the written consent of the 
Securityholder Agent, no settlement of any such claim or consent to the entry 
of any judgment with respect to such Third Party Claim shall alone be 
determinative of the validity of the claim against the Escrow Fund.  In each 
case, Parent or its affiliates shall conduct the defense of the Third Party 
Claim actively and diligently, and the Securityholder Agent and the Company 
Stockholders will cooperate with Parent or its affiliates in the defense of 
that claim and will provide full access to documents, assets, properties, 
books and records reasonably requested by Parent and material to the claim 
and will make available all individuals reasonably requested by Parent for 
investigation, depositions and trial. 
    
     (j)  ESCROW AGENT'S DUTIES.
    
           (i)  The Escrow Agent shall be obligated only for the performance 
of such duties as are specifically set forth in this Article VIII, and as set 
forth in any additional written escrow instructions which the Escrow Agent 
may receive after the date of this Agreement which are signed by an officer 
of Parent and the Securityholder Agent and approved by the Escrow Agent, and 
may rely and shall be protected in relying or refraining from acting on any 
Officer's Certificate, memorandum, instruction or other instrument reasonably 
believed to be genuine and to have been signed or presented by the proper 
party or parties.  The Escrow Agent shall not be liable for any act done or 
omitted hereunder as Escrow Agent while acting in good faith and in the 
exercise of 


                                      -55-
<PAGE>

reasonable judgment, and any act done or omitted pursuant to the advice of 
counsel shall be conclusive evidence of such good faith.
    
           (ii)  The Escrow Agent is hereby expressly authorized to disregard 
any and all warnings given by any of the parties hereto or by any other 
person, excepting only orders or process of courts of law, and is hereby 
expressly authorized to comply with and obey orders, judgments or decrees of 
any court. In case the Escrow Agent obeys or complies with any such order, 
judgment or decree of any court, the Escrow Agent shall not be liable to any 
of the parties hereto or to any other person by reason of such compliance, 
notwithstanding any such order, judgment or decree being subsequently 
reversed, modified, annulled, set aside, vacated or found to have been 
entered without jurisdiction.
    
          (iii)  The Escrow Agent shall not be liable in any respect on 
account of the identity, authority or rights of the parties executing or 
delivering or purporting to execute or deliver this Agreement or any 
documents or papers deposited or called for hereunder.
    
           (iv)  The Escrow Agent shall not be liable for the expiration of 
any rights under any statute of limitations with respect to this Agreement or 
any documents deposited with the Escrow Agent.
    
            (v)  In performing any duties under the Agreement, the Escrow 
Agent shall not be liable to any party for damages, losses, or expenses, 
except for gross negligence or willful misconduct on the part of the Escrow 
Agent.  The Escrow Agent shall not incur any such liability for (A) any act 
or failure to act made or omitted in good faith, or (B) any action taken or 
omitted in reliance upon any instrument, including any written statement or 
affidavit provided for in this Agreement that the Escrow Agent shall in good 
faith believe to be genuine, nor will the Escrow Agent be liable or 
responsible for forgeries, fraud, impersonations, or determining the scope of 
any representative authority. In addition, the Escrow Agent may consult with 
legal counsel in connection with Escrow Agent's duties under this Agreement 
and shall be fully protected in any act taken, suffered, or permitted by 
him/her in good faith in accordance with the advice of counsel.  The Escrow 
Agent is not responsible for determining and verifying the authority of any 
person acting or purporting to act on behalf of any party to this Agreement.
    
           (vi)  If any controversy arises between the parties to this 
Agreement, or with any other party, concerning the subject matter of this 
Agreement, its terms or conditions, the Escrow Agent will not be required to 
determine the controversy or to take any action regarding it.  The Escrow 
Agent may hold all documents and shares of Parent Common Stock and may wait 
for settlement of any such controversy by final appropriate legal proceedings 
or other means as, in the Escrow Agent's discretion, may be required, despite 
what may be set forth elsewhere in this Agreement.  In such event, the Escrow 
Agent will not be liable for damage.
    
     Furthermore, the Escrow Agent may at its option, file an action of 
interpleader requiring the parties to answer and litigate any claims and 
rights among themselves.  The Escrow Agent is 


                                      -56-
<PAGE>

authorized to deposit with the clerk of the court all documents and shares of 
Parent Common Stock held in escrow, except all costs, expenses, charges and 
reasonable attorney fees incurred by the Escrow Agent due to the 
interpleader.  The parties jointly and severally agree to immediately pay the 
Escrow Agent, to the extent not previously reimbursed, such amounts so 
incurred by the Escrow Agent upon the Escrow Agent's demand therefor, which 
demand may be made at any time before or after completion of such action of 
interpleader.  Upon initiating such action, the Escrow Agent shall be fully 
released and discharged of and from all obligations and liability imposed by 
the terms of this Agreement.
    
          (vii)  Parent and the Surviving Corporation agree jointly and 
severally to indemnify and hold the Escrow Agent harmless against any and all 
losses, claims, damages, liabilities, and expenses, including reasonable 
costs of investigation, counsel fees, and disbursements that may be imposed 
on Escrow Agent or incurred by Escrow Agent in connection with the 
performance of his/her duties under this Agreement, including but not limited 
to any litigation arising from this Agreement or involving its subject 
matter; provided, however, that in the event the Escrow Agent shall be the 
Non-Prevailing Party in connection with any claim or action initiated by a 
Company Stockholder or Company Stockholders, then such Company Stockholder or 
Company Stockholders shall be responsible for the indemnification of the 
Escrow Agent to the full extent provided by this paragraph.
    
          (viii) The Escrow Agent may resign at any time upon giving at least 
thirty (30) days written notice to Parent and the Securityholder Agent; 
provided, however, that no such resignation shall become effective until the 
appointment of a successor escrow agent which shall be accomplished as 
follows: Parent and the Securityholder Agent shall use their best efforts to 
mutually agree on a successor escrow agent within thirty (30) days after 
receiving such notice.  If Parent and the Securityholder Agent fail to agree 
upon a successor escrow agent within such time, the Escrow Agent shall have 
the right to appoint a successor escrow agent authorized to do business in 
the state of California. The successor escrow agent shall execute and deliver 
an instrument accepting such appointment and it shall, without further acts, 
be vested with all the estates, properties, rights, powers, and duties of the 
predecessor escrow agent as if originally named as escrow agent.  Thereafter, 
the predecessor escrow agent shall be discharged from any further duties and 
liability under this Agreement.
    
     (k)  FEES.  All fees of the Escrow Agent for performance of its duties
hereunder shall be paid by Parent.  It is understood that the fees and usual
charges agreed upon for services of the Escrow Agent shall be considered
compensation for ordinary services as contemplated by this Agreement.  In the
event that the conditions of this Agreement are not promptly fulfilled, or if
the Escrow Agent renders any service not provided for in this Agreement, or if
the parties request a substantial modification of its terms, or if any
controversy arises, or if the Escrow Agent is made a party to, or intervenes in,
any litigation pertaining to this escrow or its subject matter, the Escrow Agent
shall be reasonably compensated for such extraordinary services and reimbursed
for all costs, attorney's fees, and expenses occasioned thereby.  Parent
promises to pay these sums upon demand.


                                      -57-
<PAGE>

     (l)  CONSEQUENTIAL DAMAGES.  In no event shall the Escrow Agent be 
liable for special, indirect or consequential loss or damage of any kind 
whatsoever (including but not limited to lost profits), even if the Escrow 
Agent has been advised of the likelihood of such loss or damage and 
regardless of the form of action.


                                  ARTICLE IX
                                       
                            LIMITATION OF LIABILITY
                                       
    9.1  LIMITATION.  The maximum liability of the Company Stockholders for 
Losses incurred by Parent and/or the Surviving Corporation shall be limited 
to the Escrow Fund (the "Maximum Liability for Losses") and resort to the 
Escrow Fund shall be the exclusive right and remedy of Parent and/or the 
Surviving Corporation for Losses; PROVIDED, HOWEVER, that notwithstanding any 
provision of this Article IX, the maximum liability of the Affiliate 
Stockholders for Losses shall be determined pursuant to the Indemnity 
Agreements.  Any claim by Parent or the Surviving Corporation against any or 
all of the Company Stockholders must be made on or before the first 
anniversary of the Closing and may only be made pursuant to the procedures 
set forth in Article VIII.  The maximum liability of each Company Stockholder 
for any Losses incurred by Parent and/or the Surviving Corporation shall be 
an amount equal to the product obtained by multiplying (x) the lesser of the 
Maximum Liability for Losses or the amount of such Losses actually incurred 
by Parent or the Surviving Corporation by (y) the ratio of (a) the total 
number of shares of Parent Common Stock received by such person at the 
Closing to (b) the aggregate number of shares of Parent Common Stock issued 
at the Effective Time and shall only be payable out of the Escrow Fund in 
shares. Parent agrees to present any claims for Losses solely against the 
Escrow Fund established under Article VIII, except as may be otherwise 
permitted under the Indemnity Agreements.

                       TERMINATION, AMENDMENT AND WAIVER
                                       
    10.1  TERMINATION.  Except as provided in Section 10.2 below, this 
Agreement may be terminated and the Merger abandoned at any time prior to the 
Effective Time:
    
          (a)  by mutual consent of the Company and Parent;
    
          (b)  by Parent or the Company if:  (i) the Effective Time has not 
occurred by October 31, 1997 (provided that the right to terminate this 
Agreement under this clause 10.1(b)(i) shall not be available to any party 
whose willful failure to fulfill any obligation hereunder has been the cause 
of, or resulted in, the failure of the Effective Time to occur on or before 
such date); (ii) there shall be a final nonappealable order of a federal or 
state court in effect preventing consummation of the Merger; or (iii) there 
shall be any statute, rule, regulation or order enacted, 


                                      -58-
<PAGE>

promulgated or issued or deemed applicable to the Merger by any Governmental 
Entity that would make consummation of the Merger illegal; 
    
          (c)  by Parent if there shall be any action taken, or any statute, 
rule, regulation or order enacted, promulgated or issued or deemed applicable 
to the Merger, by any Governmental Entity, which would:  (i) prohibit 
Parent's or the Company's ownership or operation of  any portion of the 
business of the Company or (ii) compel Parent or the Company to dispose of or 
hold separate, as a result of the Merger, any portion of the business or 
assets of the Company or Parent; in either case, the unavailability of which 
assets or business would have a Material Adverse Effect on Parent or would 
reasonably be expected to have a Material Adverse Effect on Parent's ability 
to realize the benefits expected from the Merger.
    
          (d)  by Parent if it is not in material breach of its obligations 
under this Agreement and there has been a breach of any representation, 
warranty, covenant or agreement contained in this Agreement on the part of 
the Company or any Affiliate Stockholder and as a result of such breach the 
conditions set forth in Section 7.3(a), 7.3(b), 7.3(c), or 7.3(e), as the 
case may be, would not then be satisfied; PROVIDED, HOWEVER, that if such 
breach is curable by the Company within thirty (30) days through the exercise 
of its reasonable best efforts, then for so long as the Company continues to 
exercise such reasonable best efforts Parent may not terminate this Agreement 
under this Section 10.1(d) unless such breach is not cured within thirty (30) 
days (but no cure period shall be required for a breach which by its nature 
cannot be cured);
    
          (e)  by the Company if it is not in material breach of its 
obligations under this Agreement and there has been a breach of any 
representation, warranty, covenant or agreement contained in this Agreement 
on the part of Parent or Merger Sub and as a result of such breach the 
conditions set forth in Section 7.2(a) or 7.2(b), as the case may be, would 
not then be satisfied; PROVIDED, HOWEVER, that if such breach is curable by 
Parent or Merger Sub within thirty (30) days through the exercise of its 
reasonable best efforts, then for so long as Parent or Merger Sub continues 
to exercise such reasonable best efforts the Company may not terminate this 
Agreement under this Section 10.1(e) unless such breach is not cured within 
thirty (30) days (but no cure period shall be required for a breach which by 
its nature cannot be cured);

          (f)  by Parent upon the occurrence of a Material Adverse Effect on 
the Company or any Subsidiary (it being understood that a deterioration of 
general economic conditions or conditions affecting the Company's business 
generally shall not, in and of itself, constitute an event, fact, or 
condition having a Material Adverse Effect for purposes of this Section 
10.1(f)); or

          (g)  by the Company upon the occurrence of a Material Adverse 
Effect on Parent (it being understood that a decline in Parent's stock price 
or a deterioration of general economic conditions or conditions affecting 
Parent's industry generally shall not, in and of itself, constitute an event, 
fact, or condition having a Material Adverse Effect for purposes of this 
Section 10.1(g)).

     Where action is taken to terminate this Agreement pursuant to Section 
10.1, it shall be sufficient for such action to be authorized by the Board of 
Directors (as applicable) of the party taking such action.
    
     10.2 EFFECT OF TERMINATION.  In the event of termination of this 
Agreement as provided in Section 10.1, this Agreement shall forthwith become 
void and, there shall be no liability or obligation on the part of Parent, 
Merger Sub or the Company, or their respective officers, directors or 
stockholders, provided that (i) the provisions of Section 6.3 
(Confidentiality) and this Article X shall remain in full force and effect 
and survive any termination of this Agreement, and (ii) the termination of 
this Agreement shall not relieve any party from any liability for any willful 
and knowing breach of this Agreement.
    
     10.3 AMENDMENT.  Except as is otherwise required by applicable law, 
prior to the Closing, this Agreement may be amended by the parties hereto at 
any time by execution of an instrument in writing signed by Parent, the 
Company, and, in respect of matters under this Agreement that expressly 
relate to the Affiliate Stockholders, Affiliate Stockholders holding a 
majority of the outstanding Company Capital Stock held by the Affiliate 
Stockholders. Except as is otherwise required by applicable law, after the 
Closing, this Agreement may be amended by the parties hereto at any time by 
execution of an instrument in writing signed by Parent and by Company 
Stockholders who receive more than 50% of the Parent Common Stock issued or 
to be issued pursuant to Section 1.6, or by all of the Company Stockholders 
in the case of an amendment to Articles VIII or IX. 
    
     10.4 EXTENSION; WAIVER.  At any time prior to the Effective Time, Parent 
and Merger Sub, on the one hand, and the Company, on the other, may, to the 
extent legally allowed, (i) extend the time for the performance of any of the 
obligations of the other party hereto, (ii) waive any inaccuracies in the 
representations and warranties made to such party contained herein or in any 
document delivered pursuant hereto, and (iii) waive compliance with any of 
the agreements or conditions for the benefit of such party contained herein.  
Any agreement on the part of a party hereto to any such extension or waiver 
shall be valid only if set forth in an instrument in writing signed on behalf 
of such party.

     11.2 EXPENSES.  In the event the Merger is not consummated, all fees and 
expenses incurred in connection with the Merger including, without 
limitation, all legal, accounting, financial advisory, consulting and all 
other fees and expenses of third parties ("THIRD PARTY EXPENSES") incurred by 
a party in connection with the negotiation and effectuation of the terms and 
conditions of this Agreement and the transactions contemplated hereby, shall 
be the obligation of the respective party incurring such fees and expenses.  
In the event the Merger is consummated, the Surviving Corporation shall be 
responsible for the payment of all Third Party Expenses, including Third 
Party Expenses incurred by the Company and its subsidiaries; PROVIDED, 
HOWEVER, that to the extent Third Party Expenses incurred by the Company and 
its subsidiaries exceed $150,000, such excess shall be deemed a "Loss" for 
purposes of Article VIII and shall be reimbursable to Parent in accordance 
with Article VIII (without regard to the $75,000 minimum threshold for Losses 
set forth in Section 8.2(a)).  For purposes of this Agreement, the phrase 
"Third Party Expenses incurred by the Company and its subsidiaries" shall 
include all legal, accounting, financial advisory, consulting and all other 
fees and expenses of third parties incurred by the Company or any subsidiary 
of the Company in connection with the transactions contemplated by Section 
6.15(b).
    
     11.3 INTERPRETATION.  The words "include," "includes" and "including" 
when used herein shall be deemed in each case to be followed by the words 
"without limitation."  The word "agreement" when used herein shall be deemed 
in each case to mean any contract, commitment or other agreement, whether 
oral or written, that is legally binding.  The table of contents and headings 
contained in this Agreement are for reference purposes only and shall not 
affect in any way the meaning or interpretation of this Agreement.  
    
     11.4 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 


                                      -62-
<PAGE>

counterparts have been signed by each of the parties and delivered to the 
other party, it being understood that all parties need not sign the same 
counterpart.
    
     11.5 ENTIRE AGREEMENT; ASSIGNMENT.  This Agreement, the schedules and 
exhibits hereto, and the documents and instruments and other agreements among 
the parties hereto referenced herein:  (a) constitute the entire agreement 
among the parties with respect to the subject matter hereof and supersede all 
prior agreements and understandings, both written and oral, among the parties 
with respect to the subject matter hereof, including without limitation the 
Letter of Intent dated August 29, 1997 between the Company and Parent; (b) 
are not intended to confer upon any other person any rights or remedies 
hereunder; and (c) shall not be assigned by operation of law or otherwise 
except as otherwise specifically provided.
    
     11.6 SEVERABILITY.  In the event that any provision of this Agreement or 
the application thereof, becomes or is declared by a court of competent 
jurisdiction to be illegal, void or unenforceable, the remainder of this 
Agreement will continue in full force and effect and the application of such 
provision to other persons or circumstances will be interpreted so as 
reasonably to effect the intent of the parties hereto.  The parties further 
agree to replace such void or unenforceable provision of this Agreement with 
a valid and enforceable provision that will achieve, to the extent possible, 
the economic, business and other purposes of such void or unenforceable 
provision.
    
     11.7 OTHER REMEDIES.  Except as otherwise provided herein, any and all 
remedies herein expressly conferred upon a party will be deemed cumulative 
with and not exclusive of any other remedy conferred hereby, or by law or 
equity upon such party, and the exercise by a party of any one remedy will 
not preclude the exercise of any other remedy.
    
     11.8 GOVERNING LAW.  This Agreement shall be governed by and construed 
in accordance with the laws of the State of California, regardless of the 
laws that might otherwise govern under applicable principles of conflicts of 
laws thereof. Each of the parties hereto agrees that process may be served 
upon them in any manner authorized by the laws of the State of California for 
such persons and waives and covenants not to assert or plead any objection 
which they might otherwise have to such jurisdiction and such process.

     11.9 CURRENCY.  All references to "$" or "dollars" in this Agreement 
refer to the lawful currency of the United States of America.
    
     11.10     RULES OF CONSTRUCTION.  The Company and Parent hereto agree 
that they have been represented by counsel during the negotiation and 
execution of this Agreement and, therefore, waive the application of any law, 
regulation, holding or rule of construction providing that ambiguities in an 
agreement or other document will be construed against the party drafting such 
agreement or document.

     11.11     SPECIFIC PERFORMANCE.  The parties hereto agree that 
irreparable damage will occur in the event that any of the provisions of this 
Agreement are not performed in accordance with their specific terms or are 
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 hereof in any 
court of the United States or any state having jurisdiction, this being in 
addition to any other remedy to which they are entitled at law or in equity.

("Merger Sub"), and pursuant to the related Agreement of Merger (the "Agreement
of Merger") between the Company and Merger Sub and in consideration of such

<PAGE>

    13.  HOLDER REGISTRATION.  

         (a)  Parent shall use its best efforts to cause the Registrable
Securities held by each Holder to be registered under the Securities Act so as
to permit the sale thereof, and in connection therewith shall prepare and file
with the SEC within forty-five (45) days following the Effective Time a
registration statement in such form as is then available under the Securities
Act covering that number of Registrable Securities as may be requested in
writing by the Holders at the Effective Time and in accordance with
Section 4.4(b) of the Reorganization Agreement; PROVIDED, HOWEVER, that each
Holder shall provide all such information and materials and take all such action
as may be required in order to permit Parent to comply with all applicable
requirements of the Securities Act, the Exchange Act, and of the SEC, and to
obtain any desired acceleration of the effective date of such registration
statement, such provision of information and materials to be a condition
precedent to the obligations of Parent pursuant to this Declaration to register
the Registrable Securities held by each such Holder.  The offerings made
pursuant to such registration shall not be underwritten.

         (b)  Parent shall (i) prepare and file with the SEC the registration
statement in accordance with Section 2 hereof with respect to the Registrable
Securities and shall use its best efforts to cause such registration statement
to become effective as promptly as practicable after filing and to keep such
registration statement effective until the sooner to occur of (A) the date on
which all Registrable Securities included within such registration statement
have been sold or (B) the expiration of ninety (90) days after the day on which
such registration statement has been declared effective; (ii) prepare and file
with the SEC such amendments to such registration statement and amendments or
supplements to the prospectus used in connection therewith as may be necessary
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all securities registered by such registration statement;
(iii) furnish to each Holder such number of copies of any prospectus (including
any preliminary prospectus and any amended or supplemented prospectus) in
conformity with the requirements of the Securities Act, and such other
documents, as each Holder may reasonably request in order to effect the offering
and sale of the Registrable Securities to be offered and sold, but only while
Parent shall be required under the provisions hereof to cause the registration
statement to remain effective; (iv) use its best efforts to register or qualify
the Registrable Securities covered by such registration statement under the
securities or blue sky laws of such jurisdictions as each Holder shall
reasonably request (provided that Parent 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 jurisdiction where it has not
been qualified), and do any and all other acts or things which may be necessary
or advisable to enable each Holder to consummate the public sale or other
disposition of such Registrable Securities in such jurisdictions; and (v) notify
each Holder, promptly after it shall receive notice thereof, of the date and
time the registration statement and each post-effective amendment thereto has
become effective or a supplement to any prospectus forming a part of such
registration statement has been filed;


                                        -2-
<PAGE>


    3.  UNDERWRITTEN SALE.

        (a)  On or before the 45th day after the Effective Time, Parent may
determine to provide for the firmly underwritten sale of Parent Common Stock for
its own account and/or the account of other stockholders, and in connection with
such determination, shall file on or before the 45th day after the Effective
Date with the SEC a registration statement to register such Common Stock (an
"Underwritten Sale").  In the event of such determination, Parent will promptly
give to each Holder written notice thereof, and will include in the Underwritten
Sale (and any related qualification under blue sky laws or  other related
compliance) all the Registrable Securities specified by the Holders in their
notice to Parent in accordance with Section 4.4(b) of the Reorganization
Agreement, subject, however, to the marketing limitation set forth in this
Section 3.  An Underwritten Sale, including the form of underwriting agreement
to be entered into by Parent, the underwriter(s) and any selling stockholders,
shall be on customary terms.  The underwriter(s) for an Underwritten Sale shall
be selected by Parent in its sole discretion.

        (b)  The right of any Holder to registration pursuant to this Section
3 shall be conditioned upon such Holder's participation in the Underwritten Sale
and the inclusion of Registrable Securities in the Underwritten Sale to the
extent provided herein.  All Holders shall (together with Parent and the other
holders distributing their securities through the Underwritten Sale) enter into
an underwriting agreement in customary form with the managing underwriter. 
Notwithstanding any other provision of this Section 3, if the managing
underwriter determines that marketing factors require a limitation of the number
of shares to be underwritten, the managing underwriter may limit the Registrable
Securities to be included in such registration to a minimum of 30% of the total
shares to be included in the Underwritten Sale, allocated among the Holders in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities requested to be included by such Holders in accordance with
Section 4.4(b) of the Reorganization Agreement.  To facilitate the allocation of
shares in accordance with the above provision, Parent or the underwriters may
round the number of shares allocated to any Holder to the nearest 100 shares. 
If any Holder disapproves of the terms of the Underwritten Sale, he or she may
elect to withdraw therefrom by written notice to Parent and the managing
underwriter.

        (c)  The completion by Parent of an Underwritten Sale in accordance
with the provisions of this Section 3 shall be in lieu of the registration
requirements under Section 2 above and shall relieve Parent of its obligation
under Section 2, provided that the registration statement for the Underwritten
Sale has been filed on or before the 45th day after the Effective Time and that
such Underwritten Sale has been completed on or before the 75th day after the
Effective Time.  In addition, any withdrawal from or failure to participate in
the Underwritten Sale by a Holder or Holders shall also relieve Parent of its
obligations under Section 2.  In the event of a determination by Parent to
proceed with an Underwritten Sale and such Underwritten Sale for any reason
shall not be completed on or before the 75th day after the Effective Time, the
obligations of Parent to the Holders under Section 2 above shall be unaffected,
with the exception that Parent shall have an additional ten days to complete the
preparation and filing of the registration statement required thereby.


                                        -3-
<PAGE>


    4.  REGISTRATION ON FORM S-3.

        (a)  A Holder or Holders may request in writing that Parent file, at
any time after April 9, 1998 but before July 31, 1998, a registration statement
on Form S-3 (or any successor form to Form S-3) for a public offering of the
Registrable Securities, the reasonably anticipated aggregate price to the public
of which would exceed $3,000,000 (or any lesser amount if the aggregate number
of Registrable Securities to be included in such registration is not less than
200,000  shares).  Parent shall use its best efforts to cause such Registrable
Securities to be registered for the offering on such form.  Parent will
(i) promptly give written notice of the proposed registration to all other
Holders, and (ii) as soon as practicable, use its best efforts to effect such
registration as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request, together with all or such portion of the Registrable
Securities of any Holder or Holders joining in such request as are specified in
a written request received by Parent within fifteen (15) days after receipt of
such written notice from Parent.  The substantive provisions of Section 2(b)
shall be applicable to the registration initiated under this Section 4(a), with
the exception that Parent shall have no obligation to maintain the effectiveness
of such registration beyond the first anniversary of the Effective Time.

        (b)  Notwithstanding the foregoing, Parent shall not be obligated to
take any action pursuant to this Section 4: (i) in any particular jurisdiction
in which Parent would be required to execute a general consent to service of
process in effecting such registration, qualification or compliance unless
Parent is already subject to service in such jurisdiction and except as may be
required by the Securities Act; (ii) if Parent shall furnish to the Holders a
certificate signed by the President of Parent stating that, in the good faith
judgment of the Board of Directors, it would be seriously detrimental to Parent
or its stockholders for registration statements to be filed in the near future,
then Parent's obligation to use its best efforts to file a registration
statement shall be deferred for a single period not to exceed forty-five (45)
days from the receipt of the request to file such registration by a Holder or
Holders; or (iii) in the event that Parent notifies the Holders that it has
determined, in consultation with legal counsel, that restrictions on transfer
are no longer applicable under United States securities laws and such
Registrable Securities are then freely tradeable.

    5.  SUSPENSION OF PROSPECTUS.  Under any registration statement filed
pursuant to Section 2 or Section 4 hereof, Parent may restrict disposition of
Registrable Securities, and a Holder will not be able to dispose of such
Registrable Securities, if Parent shall have delivered a notice in writing to
such Holder stating that a delay in the disposition of such Registrable
Securities is necessary because Parent, in its reasonable judgment, has
determined that such sales would require public disclosure by Parent of material
nonpublic information that is not included in such registration statement.  In
the event of the delivery of the notice described above by Parent, Parent shall
use its best efforts to amend such registration statement and/or amend or
supplement the related prospectus if necessary and to take all other actions
necessary to allow the proposed sale to take place as promptly as possible,
subject, however, to the right of Parent to delay further sales of Registrable
Securities until the conditions or circumstances referred to in the notice have
ceased to exist or have been disclosed.  Such right to delay sales of
Registrable Securities shall not exceed thirty (30) days, and may not be
exercised by Parent more 


                                        -4-
<PAGE>


than once for each registration under Section 2 and Section 4.  Any such 
delay shall result in a corresponding extension of the period of time that 
Parent is required to maintain the effectiveness of the registration 
statement under Section 2 and Section 4.

     6.  EXPENSES.  All of the out-of-pocket expenses incurred in connection
with any registration of Registrable Securities pursuant to this Declaration,
including, without limitation, all SEC, Nasdaq National Market and blue sky
registration and filing fees, printing expenses, transfer agents' and
registrars' fees, and the reasonable fees and disbursements of Parent's outside
counsel and independent accountants and a single counsel for all of the Holders,
shall be paid:  (i) in respect of a registration under Section 2, one-half by
Parent and one-half by the Holders in the proportion of the Registrable
Securities included in such registration; (ii) in respect of an Underwritten
Sale under Section 3, by Parent; and (iii) in respect of a registration under
Section 4, by the Holders in the proportion of the Registrable Securities
included in such registration.  Underwriting discounts and commissions shall be
paid by the Holders.

     7.  INDEMNIFICATION.  In the event of any offering registered pursuant to
this Declaration:

         (a)  Parent will indemnify each Holder, each of its officers,
directors and partners and such Holder's legal counsel and independent
accountants, and each person controlling such Holder within the meaning of
Section 15 of the Securities Act, with respect to which registration,
qualification or compliance has been effected pursuant to this Declaration, and
each underwriter, if any, and each person who controls any underwriter within
the meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages and liabilities (or actions in respect thereof), including any
of the foregoing incurred in settlement of any litigation, commenced or
threatened, arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any registration statement,
prospectus, offering circular or other document, or any amendment or supplement
thereto, incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they are made, not misleading, or any
violation by Parent of any rule or regulation promulgated under the Securities
Act, or state securities laws, or common law, applicable to Parent in connection
with any such registration, qualification or compliance, and will reimburse each
such Holder, each of its officers, directors and partners and such Holder's
legal counsel and independent accountants, and each person controlling such
Holder, each such underwriter and each person who controls any such underwriter,
for any legal and any other expenses reasonably incurred in connection with
investigating, preparing or defending any such claim, loss, damage, liability or
action, provided that Parent will not be liable in any such case to the extent
that any such claim, loss, damage, liability or expense arises out of or is
based in any untrue statement or omission or alleged untrue statement or
omission, made in reliance upon and in conformity with written information
furnished to Parent in an instrument duly executed by such Holder or underwriter
and stated to be specifically for use therein.

         (b)  Each Holder will, if Registrable Securities held by such Holder
are included in the securities as to which such registration, qualification or
compliance is being effected, indemnify 


                                        -5-
<PAGE>


Parent, each of its directors and officers and its legal counsel and 
independent accountants, each underwriter, if any, of Parent's securities 
covered by such a registration statement, each person who controls Parent or 
such underwriter within the meaning of Section 15 of the Securities Act, and 
each other such Holder, each of its officers and directors and each person 
controlling such Holder within the meaning of Section 15 of the Securities 
Act, against all claims, losses, damages and liabilities (or actions in 
respect thereof) arising out of or based on any untrue statement (or alleged 
untrue statement) of a material fact contained in any such registration 
statement, prospectus, offering circular or other document, or any omission 
(or alleged omission) to state therein a material fact required to be stated 
therein or necessary to make the statements therein not misleading, and will 
reimburse Parent, such Holders, such directors, officers, legal counsel, 
independent accountants, underwriters or control persons for any legal or any 
other expenses reasonably incurred in connection with investigating or 
defending any such claim, loss, damage, liability or action, in each case to 
the extent, but only to the extent, that such untrue statement (or alleged 
untrue statement) or omission (or alleged omission) is made in such 
registration statement, prospectus, offering circular or other document in 
reliance upon and in conformity with written information furnished to Parent 
by an instrument duly executed by such Holder and stated to be specifically 
for use therein; provided, however, that the obligations of such Holders 
hereunder shall be limited to an amount equal to the gross proceeds before 
expenses and commissions to each such Holder of Registrable Securities sold 
as contemplated herein.

         (c)  Each party entitled to indemnification under this Section 7 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has written notice of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations under this Declaration, except to the extent, but only to the
extent, that the Indemnifying Party's ability to defend against such claim or
litigation is impaired as a result of such failure to give notice.  No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter any settlement which does not include as an unconditional term
thereof the giving by the claimant or plaintiff to the Indemnified Party of a
release from all liability in respect to such claim or litigation.

         (d)  The obligations of Parent and each Holder under this Section 7
shall survive the completion of any offering of Registrable Securities in a
registration statement under this Declaration and otherwise.

         (e)  Notwithstanding the foregoing, to the extent the provisions of
this Section 7 are inconsistent with or conflict with the terms of any
underwriting, indemnification, selling or similar agreement entered into by a
Holder in connection with the offer and sale of Registrable Securities 


                                        -6-
<PAGE>


pursuant to a registration effected pursuant to this Declaration, the terms 
of such agreement shall govern and shall supersede the provisions of this 
Declaration.

     8.  REPORTS UNDER EXCHANGE ACT.  Parent agrees to:

         (a)  use its commercially reasonable efforts to file with the SEC in a
timely manner all reports and other documents required of Parent under the
Securities Act and the Exchange Act; and

         (b)  furnish to each Holder, forthwith upon request (i) a written
statement by Parent that it has complied with the reporting requirements of 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), and (ii) a copy of the most recent annual or quarterly report of
Parent.

     9.  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause Parent to
register Registrable Securities pursuant to this Declaration may be assigned by
a Holder to a transferee of Registrable Securities only if: (a) Parent is, prior
to such transfer, furnished with written notice of the name and address of such
transferee and the Registrable Securities with respect to which such
registration rights are being assigned and a copy of a duly executed written
instrument in form reasonably satisfactory to Parent by which such transferee
assumes all of the obligations and liabilities of its transferor hereunder and
agrees itself to be bound hereby; (b) immediately following such transfer the
disposition of such Registrable Securities by the transferee is restricted under
the Securities Act; and (c) such assignment includes all of the Registrable
Securities originally issued to the transferee, or such lesser amount if not
less than 10,000 shares of Registrable Securities; PROVIDED, HOWEVER, that such
10,000 share limitation shall not apply to transfers by a Holder to
shareholders, partners, retired partners of the Holder (including spouses and
ancestors, lineal descendants, and siblings of such partners or spouses who
acquire Registrable Securities by right, will, or intestate succession) if all
such transferees or assignees agree in writing to appoint a single
representative as their attorney-in-fact for the purpose of receiving any
notices and exercising their rights under this Declaration..

     10. ESCROW SHARES.  Shares of Parent Common Stock which are subject to the
Escrow in accordance with Article VIII of the Reorganization Agreement are
eligible for inclusion as registrable Securities hereunder, but only to the
extent that (i) the Holder agrees to remit all proceeds resulting from the sale
of such shares to the Escrow Agent as substitute collateral and (ii) the per
share amount of such proceeds is not less than the Parent Price Per Share.

     11. AMENDMENT OF REGISTRATION RIGHTS.  Holders of a majority of the
Registrable Securities from time to time outstanding may, with the consent of
Parent, amend the registration rights granted hereunder.

                             AFFILIATES AGREEMENT
<PAGE>

                              AFFILIATE AGREEMENT


    This Affiliate Agreement ("Agreement") is made and entered into as of
September ___, 1997, between Peregrine Systems, Inc., a Delaware corporation
("Parent"), and the undersigned stockholder ("Stockholder") of United Software,
Inc., a Delaware corporation (the "Company").

    A. Parent and the Company propose to enter into an Agreement and Plan of 
Reorganization (the "Reorganization Agreement") pursuant to which a 
subsidiary of Parent will merge with and into the Company (the "Merger"), and 
the Company will become a subsidiary of Parent (capitalized terms not 
otherwise defined herein shall have the meanings ascribed to them in the 
Reorganization Agreement);

    B. Pursuant to the Merger, at the Effective Time outstanding shares of 
Company Capital Stock, including shares owned by Stockholder, will be 
converted into the right to receive shares of Parent Common Stock;

    C. The execution and delivery of this Agreement by Stockholder is a 
material inducement to Parent to enter into the Reorganization Agreement; and

    D. Stockholder has been advised that Stockholder may be deemed to be an 
"affiliate" of the Company, as the term "affiliate" is used for purposes of 
paragraphs (c) and (d) of Rule 145 of the Rules and Regulations (the "Rules 
and Regulations") of the Securities and Exchange Commission (the "SEC") under 
the Securities Act of 1933, as amended (the "Securities Act"), although 
nothing contained herein shall be construed as an admission by Stockholder 
that Stockholder is in fact an affiliate of the Company.

    NOW, THEREFORE, intending to be legally bound, the parties hereby agree as
follows:

    1. ACKNOWLEDGMENT BY STOCKHOLDER.  Stockholder acknowledges and
understands that the representations, warranties and covenants by Stockholder
set forth herein will be relied upon by Parent and the Company.

    2. COMPLIANCE WITH RULE 145 AND THE SECURITIES ACT.

         (a)  Stockholder has been advised that (i) the issuance of shares of 
Parent Common Stock in connection with the Merger initially will not be 
registered under the Securities Act, (ii) Parent will use its best efforts to 
prepare and file a registration statement covering certain of the shares of 
Parent Common Stock issued in connection with the Merger within forty-five 
(45) days after the Effective Time, all in accordance with the Declaration of 
Registration Rights delivered by the Company pursuant to the Reorganization 
Agreement, (iii) Stockholder may be deemed to be an affiliate of the Company, 
and (iv)  no sale, transfer or other disposition by Stockholder of Parent 
Common Stock will be registered under the Securities Act (except in 
accordance with the Declaration of Registration Rights).  Accordingly, 
Stockholder agrees not to sell, transfer or otherwise dispose of Parent 
Common Stock issued to Stockholder in the Merger (except pursuant to a 
registration) unless (i) such sale, transfer or other disposition is made in 
conformity with the requirements of Rule 145(d) promulgated under the 


<PAGE>


Securities Act, or (ii) Stockholder delivers to Parent a written opinion of 
counsel, reasonably acceptable to Parent in form and substance, that such 
sale, transfer or other disposition is otherwise exempt from registration 
under the Securities Act.  

         (b)  (i)  Parent will give stop transfer instructions to its transfer
agent with respect to the Parent Common Stock received by Stockholder pursuant
to the Merger and there will be placed on the certificates representing such
Common Stock, or any substitutions therefor, a legend stating in substance:

         "The shares represented by this certificate were issued in a
         transaction to which Rule 145 applies and may only be transferred
         in conformity with Rule 145(d) or in accordance with a written
         opinion of counsel, reasonably acceptable to the issuer in form
         and substance, that such transfer is exempt from registration
         under the Securities Act of 1933." 

              (ii) In addition to the foregoing legend, shares of Parent Common
Stock issued in reliance on the exemption from the registration requirements of
the Securities Act set forth in Regulation S thereof will bear the following
legend:

         "The shares represented by this certificate have been issued
         in a transaction exempt from the registration requirements
         of the United States Securities Act of 1933, as amended,
         pursuant to Regulation S thereunder and may not be sold,
         transferred, assigned, or hypothecated absent registration
         except in compliance with Regulation S, Rule 144, or an
         opinion counsel, satisfactory to the Company, that such
         registration is not required under the Act, or a no-action
         letter from the United States Securities and Exchange
         Commission.

              (iii)     The foregoing legends shall be removed (by delivery of
a substitute certificate without such legend) if Stockholder delivers to Parent
(i) satisfactory written evidence that the shares have been sold in compliance
with Regulation S or Rule 145 (in which case, the substitute certificate will be
issued in the name of the transferee), or (ii) an opinion of counsel, in form
and substance reasonably satisfactory to Parent, to the effect that public sale
of the shares by the holder thereof is no longer subject to Rule 145.

    3.   MARKET STAND-OFF AGREEMENT  The Stockholder agrees, in connection with
any Underwritten Sale (as defined in the Declaration of Registration Rights),
regardless of whether the Stockholder elects to exercise its right to
participate therein pursuant to the Declaration of Registration Rights, that he,
she, or it will not sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of any securities of Parent (other than those
included in the Underwritten Sale) without the prior written consent of the
Company and the underwriters of the Underwritten Sale, for such period of time
(not to exceed 180 days and in no event to extend beyond April 8, 1998) from the
effective date of such registration as the Company and the underwriters may
specify.  The Stockholder


                                      -2-
<PAGE>


agrees that the Company may instruct its transfer agent to place 
stop-transfer notations in its records to enforce the provisions of this 
section.

    4.   REPRESENTATIONS, WARRANTIES AND COVENANTS RELATED TO TAX EFFECTS OF

partner's risk of ownership by short sale or otherwise, or other disposition,
directly or indirectly (such actions being collectively referred to herein as a
"Sale") of any shares of Parent Common Stock to be received by Stockholder or
its partners in the Merger such that the aggregate fair market value, as of the
Effective Time, of the shares subject to such Sale would exceed 40% of the
aggregate fair market value of all shares of outstanding Company Common Stock,
immediately prior to the Merger held by Stockholder or its partners, as
applicable.  For purposes of the preceding sentence, shares of Company Capital
Stock (or the portion thereof) (i) with respect to which Stockholder will

without limitation, cash to be received in lieu of fractional shares of Parent
Common Stock) and/or (ii) with respect to which a Sale (A) occurred after
January 1, 1997 or otherwise in contemplation of the Merger or (B) will occur

a Plan;

         (d)  Stockholder will not exercise dissenters' rights in connection
with the Merger;

         (e)  Stockholder is not aware of, or participating in, and is not

stockholders of the Company to engage in a Sale or Sales of the Parent Common
Stock to be received in the Merger such that the aggregate fair market value, as
of the Effective Time, of the shares subject to such Sales would exceed 40% of
the aggregate fair market value of all shares of outstanding Company Capital
Stock immediately prior to the Merger.  For purposes of the preceding sentence,
shares of Company Capital Stock (or the portion thereof) (i) with respect to
which a Company stockholder receives consideration in the Merger other than
Parent Common Stock (including, without limitation, cash received pursuant to
the exercise of dissenters' rights or in lieu of fractional shares of Parent
Common Stock) or (ii) with respect to which a Sale occurs prior to and in
contemplation of the Merger, shall be considered shares of outstanding Company
Capital Stock exchanged for Parent Common Stock in the Merger and then disposed
of pursuant to a Plan.


                                      -3-
<PAGE>


         (f)  Except to the extent written notification to the contrary is
received by Parent from Stockholder prior to the Merger, the representations
contained herein shall be true and correct at all times from the date hereof
through the Effective Time.

         (g)  Stockholder understands that the Company, Parent and their
respective stockholders, as well as legal counsel to the Company and Parent (in
connection with rendering their opinions that the Merger will be a
"reorganization" within the meaning of Section 368(a) of the Code) will be
relying on (a) the truth and accuracy of the representations contained herein
and (b) Stockholder's performance of the obligations set forth herein.

         (h)  Except for the Company Capital Stock and options to purchase
Company Common Stock set forth in Appendix A hereto, Stockholder does not

any equity securities of the Company.

    5.   MISCELLANEOUS.

         (a)  For the convenience of the parties hereto, 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 document.

         (b)  This Agreement shall be enforceable by, and shall inure to the
benefit of and be binding upon, the parties hereto and their respective
successors and assigns.  As used herein, the term "successors and assigns" shall
mean, where the context so permits, heirs, executors, administrators, trustees
and successor trustees, and personal and other representatives.

         (c)  This Agreement shall be governed by and construed, interpreted
and enforced in accordance with the internal laws of the State of California.

         (d)  If a court of competent jurisdiction determines that any
provision of this Agreement is not enforceable or enforceable only if limited in
time and/or scope, this Agreement shall continue in full force and effect with
such provision stricken or so limited.

         (e)  Counsel to the parties to the Reorganization Agreement shall be
entitled to rely upon this Agreement as needed.

         (f)  This Agreement shall not be modified or amended, or any right
hereunder waived or any obligation excused, except by a written agreement signed
by both parties.

<PAGE>

                               VOTING AGREEMENT

    This Voting Agreement ("Agreement") is made and entered into as of 
September ___, 1997, between Peregrine Systems, Inc., a Delaware corporation 
("Parent"), and the undersigned stockholder ("Stockholder") of United 
Software, Inc., a Delaware corporation (the "Company").

                                   RECITALS

    A.   Concurrently with the execution of this Agreement, Parent, the 
Company and  French Acquisition Corporation, a Delaware corporation and a 
wholly owned subsidiary of Parent ("Merger Sub"), have entered into an 
Agreement and Plan of Reorganization (the "Reorganization Agreement") which 
provides for the merger (the "Merger") of Merger Sub with and into the 
Company.  Pursuant to the Merger, shares of capital stock of the Company will 
be converted into Common Stock of Parent on the basis described in the 
Reorganization Agreement.

    B.   Stockholder is the record holder and beneficial owner (as defined in 
Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the 
"Exchange Act")) of such number of shares of the outstanding Common Stock of 
the Company as is indicated on the final page of this Agreement (the 
"Shares").

    C.   Parent desires Stockholder to agree, and Stockholder is willing to 
agree, not to transfer or otherwise dispose of any of the Shares, or any 
other shares of capital stock of the Company acquired hereafter and prior to 
the Expiration Date (as defined in Section 1.1 below, except as otherwise 
permitted hereby), and to vote the Shares and any other such shares of 
capital stock of the Company so as to facilitate consummation of the Merger.

    NOW, THEREFORE, intending to be legally bound, the parties agree as 
follows:

    1.  AGREEMENT TO RETAIN SHARES.

         1.1  TRANSFER AND ENCUMBRANCE.  Stockholder agrees not to transfer 
(except as may be specifically required by court order or approved in writing 
in advance by Parent), sell, exchange, pledge or otherwise dispose of or 
encumber any of the Shares or any New Shares as defined in Section 1.2 below, 
or to make any offer or agreement relating thereto, at any time prior to the 
Expiration Date.  As used herein, the term "Expiration Date" shall mean the 
earlier to occur of (i) such date and time as the Merger shall become 
effective in accordance with the terms and provisions of the Reorganization 
Agreement, and (ii) such date and time as the Reorganization Agreement shall 
be terminated pursuant to Article X thereof.

         1.2  ADDITIONAL PURCHASES.  Stockholder agrees that any shares of 
capital stock of the Company that Stockholder purchases or with respect to 
which Stockholder otherwise acquires beneficial 


                                       

<PAGE>

ownership after the execution 
of this Agreement and prior to the Expiration Date ("New Shares") shall be 
subject to the terms and conditions of this Agreement to the same extent as 
if they constituted Shares.

    2.  AGREEMENT TO VOTE SHARES.  At every meeting of the stockholders of 
the Company called with respect to any of the following, and at every 
adjournment thereof, and on every action or approval by written consent of 
the stockholders of the Company with respect to any of the following, 
Stockholder shall vote the Shares and any New Shares:  (i) in favor of 
approval of the Reorganization Agreement and the Merger and any matter that 
could reasonably be expected to facilitate the Merger (including without 
limitation the conversion of any shares of Preferred Stock of the Company 
into Common Stock of the Company immediately prior to or at the effective 
time of the Merger, consistent with the provisions of the Company's 
Certificate of Incorporation) and (ii) against approval of any proposal made 
in opposition to or in competition with consummation of the Merger and 
against any merger, consolidation, sale of assets, reorganization or 
recapitalization, with any party other than with Parent and its affiliates 
and against any liquidation or winding up of the Company (each of the 
foregoing is hereinafter referred to as an "Opposing Proposal").  Stockholder 
agrees not to take any actions contrary to Stockholder's obligations under 
this Agreement.

    3.  OTHER STOCKHOLDER AGREEMENTS.  In connection with the Merger, the 
Stockholder also agrees (i) to waive in writing any notice or other similar 
provision necessary to effect the Merger or the transactions contemplated 
thereby, including, without limitation, waiver of the notice provision in the 
Put Agreement dated April 16, 1997 between the Purchaser and the Company, 
(ii) to waive in writing any applicable rights set forth in the Stockholders' 
Agreement dated April 16, 1997 or the undated Investors' Rights Agreement 
among the Company and the stockholders identified therein and to agree to 
terminate such agreements upon consummation of the Merger, and (iii) to 
execute a written notice of elective conversion of all shares of Preferred 
Stock of the Company held by such Stockholder immediately prior to the 
closing of the Merger.

    4.  IRREVOCABLE PROXY.  Concurrently with the execution of this 
Agreement, Stockholder agrees to deliver to Parent 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 the Company beneficially owned 
(as such term is defined in Rule 13d-3 under the Exchange Act) by Stockholder 
set forth therein.

    5.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF STOCKHOLDER.  
Stockholder hereby represents, warrants and covenants to Parent as follows:

         5.1  OWNERSHIP OF SHARES.  Stockholder (i) is the beneficial owner 
of the Shares, which at the date hereof and at all times up until the 
Expiration Date will be free and clear of any liens, claims, options, charges 
or other encumbrances except for any rights of repurchase or rights of first 
refusal granted to the Company; (ii) does not beneficially own any shares of 
capital stock of the Company other than the Shares; and (iii) has full power 
and authority to make, enter into and carry out the terms of this Agreement 
and the Proxy.

<PAGE>


         5.2  NO PROXY SOLICITATIONS.  Stockholder will not, and will not 
permit any entity under Stockholder's control to:  (i) solicit proxies or 
become a "participant" in a "solicitation" (as such terms are defined in 
Regulation 14A under the Exchange Act) with respect to an Opposing Proposal 
or otherwise encourage or assist any party in taking or planning any action 
that would compete with, restrain or otherwise serve to interfere with or 
inhibit the timely consummation of the Merger in accordance with the terms of 
the Reorganization Agreement; (ii) initiate a stockholders' vote or action by 
consent of the Company stockholders with respect to an Opposing Proposal; or 
(iii) become a member of a "group" (as such term is used in Section 13(d) of 
the Exchange Act) with respect to any voting securities of the Company with 
respect to an Opposing Proposal.

    6.  ADDITIONAL DOCUMENTS.  Stockholder hereby covenants and agrees to 
execute and deliver any additional documents necessary or desirable, in the 
reasonable opinion of Parent, to carry out the intent of this Agreement.

    7.  CONSENT AND WAIVER.  Stockholder hereby gives any consents or waivers 
that are reasonably required for the consummation of the Merger under the 
terms of any agreements to which Stockholder is a party or pursuant to any 
rights Stockholder may have.

    8.  TERMINATION.  This Agreement and the Proxy delivered in connection 
herewith shall terminate and shall have no further force or effect as of the 
Expiration Date.

    9.  MISCELLANEOUS.

         9.1  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.

         9.2  BINDING EFFECT AND ASSIGNMENT.  This Agreement and all of the 
provisions hereof shall be binding upon and inure to the benefit of the 
parties hereto and their respective successors and permitted assigns, but, 
except as otherwise specifically provided herein, neither this Agreement nor 
any of the rights, interests or obligations of the parties hereto may be 
assigned by either of the parties without prior written consent of the other.

         9.3  AMENDMENTS AND MODIFICATION.  This Agreement may not be 
modified, amended, altered or supplemented except upon the execution and 
delivery of a written agreement executed by the parties hereto.

         9.4  SPECIFIC PERFORMANCE; INJUNCTIVE RELIEF.  The parties hereto 
acknowledge that Parent will be irreparably harmed and that there will be no 
adequate remedy at law for a violation of any of the covenants or agreement 
of Stockholder set forth herein.  Therefore, it is agreed that, in addition

<PAGE>

                           NON-COMPETITION AGREEMENT



    This Agreement is entered into by and between Peregrine Systems, Inc.
("Parent"), United Software, Inc., a Delaware corporation (the "Company") and
__________________ ("Stockholder") as of September __, 1997.

                                   RECITALS
                                       
    A.   Pursuant to that certain Agreement and Plan of Reorganization (the 
"Reorganization Agreement") dated as of September  __, 1997 by and between 
Parent, French Acquisition Corporation ("Merger Sub") and the Company, Merger 
Sub will merge with and into the Company (the "Merger") and any shares of 
Company capital stock owned by Stockholder will be exchanged for Parent 
Common Stock and any options and stock purchase rights to acquire Company 
Common Stock will be assumed by Parent and become options or stock purchase 
rights to acquire Parent Common Stock;

    B.   Stockholder owns an equity interest in the Company (whether through
outstanding capital stock or options to purchase capital stock), has served as
its __________________________________ and has gained substantial knowledge and
expertise in connection with the Company's products, organization and customers;

    C.   Parent and Stockholder acknowledge that it would be detrimental to
Parent if Stockholder would compete with Parent following the Merger;

    D.   The Company is engaged in the design, development, marketing,
distribution and licensing of management application software that automates
information infrastructures.

    E.   It is a covenant of the Company pursuant to the Reorganization
Agreement that certain key Stockholders of the Company, including Stockholder,
enter into this Agreement;

    F.   As inducement to Parent to consummate the Merger, and in consideration
of the amounts paid to shareholders of the Company under the Merger Agreement,
Stockholder desires to agree with Parent as further provided herein;

    NOW, THEREFORE, intending to be legally bound hereby, the parties hereto
agree as follows:


<PAGE>

    1.   ACKNOWLEDGMENTS BY STOCKHOLDER.  Stockholder acknowledges that the
promises and restrictive covenants that Stockholder is providing in this
Agreement are reasonable and necessary to the protection of Parent's business
and Parent's legitimate interests in its acquisition of the Company (including
the Company's goodwill) pursuant to the Reorganization Agreement.

    2.   NON-COMPETITION.  

         (a)  The parties understand and agree that this Agreement is entered
into in connection with the Merger.  The parties further understand and agree
that Stockholder is a key and significant member of the Company, owns a
significant number of shares (or rights to acquire a significant number of
shares) of the Company and that the Merger is contingent upon Stockholder
entering into this Agreement, including this non-competition provision.   In
addition, the parties understand that prior to the Merger, the Company was
engaged in or intends to engage in business in each of the fifty states of the
United States, Europe, ____________ and ________________.  The parties further
understand that Parent is currently engaged in business in each of the fifty
states of the United States, and elsewhere on a worldwide basis (with resources
currently deployed in Europe, Latin America, and the Pacific Rim).  (The United
States and the regions set forth above in the preceding two sentences shall
hereafter be referred to as the "Geographic Scope of the Business".) 
Stockholder further acknowledges that the Company and Parent following the
Merger will continue conducting such business in all parts of the Geographic
Scope of the Business.

         (b)  During the period commencing on the closing date of the Merger
and ending eighteen (18) months thereafter (the "Restriction Period"), without
the prior written consent of the Chief Executive Officer of Parent, Stockholder
shall not either as an individual or as an Stockholder, agent, consultant,
advisor, independent contractor, general partner, officer, director, shareholder
or investor of any person, firm, corporation, partnership or other entity:

                (i)  participate or engage in an enterprise whose business is
the design, development, marketing, distribution and/or licensing of asset
management or consolidated service desk application software ("Competitive
Activity").  Enterprise shall refer to the subsidiary, division, company or
other entity at which Stockholder is employed. 

               (ii)  induce or attempt to induce any person who at the time of
such inducement is an Stockholder of the Company or Parent to perform work or
services for any other person or entity other than the Company or Parent; or

         Notwithstanding the foregoing, Stockholder may purchase, directly or
indirectly, up to 2% of any class of "publicly traded securities" of any person
or entity which owns a Business engaged in a Competitive Activity or be employed
by or act as a consultant to a subsidiary or division of a corporation engaged
in a Competitive Activity so long as such subsidiary or division is not engaged
in a Competitive Activity and such employment or consulting is not with respect
to a Competitive Activity.  For the purposes of this Section 1.1, the term
"publicly traded securities" shall mean securities that are traded on a national
securities exchange in the United States or listed on the Nasdaq National
Market. 

                                       -2-
<PAGE>

         If any restriction set forth in this Section 2 above is held to be
unreasonable or unenforceable, then Stockholder agrees, and hereby submits, to
the reduction and limitation of such prohibition to such area or period as shall
be deemed reasonable. 

    3.   NONSOLICITATION.  Stockholder further agrees that, during the
Restriction Period, Stockholder will not:

         (a)  personally or through others, encourage, induce, attempt to
induce, solicit or attempt to solicit (on Stockholder's own behalf or on behalf
of any other person or entity) any employee of the Company, Parent or any of
Parent's subsidiaries to leave his or her employment with the Company, Parent or
any of Parent's subsidiaries;

         (b)  employ, or permit any entity over which Stockholder exercises
voting control to employ, any person who shall have terminated his or her
employment with the Company, Parent or any of Parent's subsidiaries during the
Restriction Period; or

         (c)  personally or through others, interfere or attempt to interfere
with the relationship or prospective relationship of the Company, Parent or any
of Parent's subsidiaries with any person or entity that is, was or is expected
to become a customer or client of the Company, Parent or any of Parent's
subsidiaries.

    4.   INDEPENDENCE OF OBLIGATIONS.  The covenants and obligations of
Stockholder set forth in this Agreement shall be construed as independent of any
other agreement or arrangement between Stockholder, on the one hand, and the
Company or Parent, on the other.

    5.   SPECIFIC PERFORMANCE.  Stockholder agrees that in the event of any
breach by Stockholder of any covenant, obligation or other provision contained
in this Agreement, Parent and the Company shall be entitled (in addition to any
other remedy that may be available to them) to the extent permitted by
applicable law (a) a decree or order of specific performance to enforce the
observance and performance of such covenant, obligation or other provision, and
(b) an injunction restraining such breach or threatened breach.

    6.   NON-EXCLUSIVITY.  The rights and remedies of Parent and the Company
hereunder are not exclusive of or limited by any other rights or remedies which
Parent or the Company may have, whether at law, in equity, by contract or
otherwise, all of which shall be cumulative (and not alternative).  Without
limiting the generality of the foregoing, the rights and remedies of Parent and
the Company hereunder, and the obligations and liabilities of Stockholder
hereunder, are in addition to their respective rights, remedies, obligations and
liabilities under the law of unfair competition, misappropriation of trade
secrets and the like.

    7.   SUCCESSORS, ASSIGNS, MERGER.  This Agreement shall be binding upon and
shall inure to the benefit of Parent, the Company and their respective
successors and assigns.  This Agreement shall 

                                       -3-
<PAGE>

be binding upon Stockholder and shall inure to his benefit and to the benefit 
of his heirs, executors, administrators and legal representatives, but shall 
not be assignable by Stockholder.

    8.   ENTIRE AGREEMENT.  This Agreement constitutes the entire agreement
between Parent and Stockholder relating to the matters herein provided for. 
This Agreement supersedes and replaces any prior verbal or written agreements
between the parties.  This Agreement may be amended or altered only in a writing
signed by the Chief Executive Officer of Parent and Stockholder.

    9.   APPLICABLE LAW; SEVERABILITY.  This Agreement shall be construed and
interpreted in accordance with the laws of the State of California without
regard to conflicts of laws and principles.  Each provision of this Agreement is
severable from the others, and if any provision hereof shall be to any extent
unenforceable it and the other provisions hereof shall continue to be
enforceable to the full extent allowable, as if such offending provision had not
been a part of this Agreement.

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

                   AFFILIATE STOCKHOLDER INDEMNITY AGREEMENT

<PAGE>

                              INDEMNITY AGREEMENT

    This Indemnity Agreement (the "Indemnity Agreement") is entered into as of
September __, 1997, by and among Peregrine Systems, Inc., a Delaware corporation
("Parent"), and each of the stockholders of United Software, Inc., a Delaware
corporation (the "Company"), identified on SCHEDULE A attached hereto
(collectively, the "Selling Stockholders" and individually a "Selling
Stockholder").

                                   RECITALS

    A.   Each of the Selling Stockholders is a stockholder of the Company;

    B.   Parent, French Acquisition Corporation, a Delaware corporation and a
wholly-owned subsidiary of Parent ("Merger Sub"), and the Company have entered
into an Agreement and Plan of Reorganization, effective as of August 29, 1997
(the "Reorganization Agreement"), providing for the merger of Merger Sub into
the Company (the "Merger").  The Reorganization Agreement contemplates that,
upon consummation of the Merger, (i) holders of shares of the capital stock of
the Company will receive shares of common stock of Parent ("Parent Common
Stock") in exchange for their shares of capital stock of the Company and (ii)
the Company will become a wholly owned subsidiary of Parent.  It is accordingly
contemplated that the Selling Stockholders will receive shares of Parent Common
Stock in the Merger;

    C.   As a condition precedent to Parent's execution of the Reorganization
Agreement and related agreements, Parent has required that each of the Selling
Stockholders enter into this Indemnity Agreement; and

    D.   Each of the Selling Stockholders has agreed to enter into this
Indemnity Agreement in order to induce Parent to consummate the Merger.

    NOW, THEREFORE, the parties to this Indemnity Agreement, intending to be
legally bound, agree as follows:

    1.    DEFINED TERMS.

    Capitalized terms used and not otherwise defined in this Indemnity
Agreement shall have the meanings assigned to them in the Reorganization
Agreement.

    2.    REPRESENTATIONS AND WARRANTIES.  Each of the Selling Stockholders
severally represents and warrants, to the best of his, her, or its knowledge, to
and for the benefit of the Indemnitees (as defined in Section 4.2), as of the
date of this Indemnity Agreement as follows:

          2.1  Schedule 2.1(b) of the Reorganization Agreement identifies for 
each Subsidiary the authorized capital stock, the identity and address of 
each holder of capital stock of such Subsidiary, and the number of shares of 
capital stock of each Subsidiary held by such holder (as updated prior to the 

<PAGE>


Closing to reflect the transactions contemplated by Section 6.15 of the 
Reorganization Agreement).  Except as set forth in Schedule 2.1(b),  all of 
the outstanding shares of the capital stock of each Subsidiary have been duly 
authorized and validly issued, are fully paid and nonassessable, and are 
wholly owned by the Company, directly or indirectly through a Subsidiary, 
free and clear of any lien, adverse claim, security interest, equity or other 
encumbrance.  Except as described in Schedule 2.1(b), there are no options, 
warrants, calls, rights, commitments or agreements of any character, written 
or oral, to which any Subsidiary is a party or by which any Subsidiary is 
bound, obligating such Subsidiary to issue, deliver, sell, repurchase or 
redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any 
shares of such Subsidiary's capital stock.

         2.2  The authorized Company Capital Stock consists of 15,000,000 
shares of authorized Common Stock, par value $0.001 per share, of which 
1,563,708 shares are issued and outstanding, and 10,000,000 shares of 
authorized Preferred Stock, par value $0.001 per share.  Of the authorized 
Preferred Stock, 3,898,084 shares have been designated as Series A Preferred 
Stock, of which 819,101 shares are issued and outstanding, and 2,009,530 
shares have been designated as Series B Preferred Stock, all of which shares 
are issued and outstanding.  The Company Capital Stock is held of record by 
the persons with the addresses of record and in the amounts identified on 
Schedule 2.2(a) of the Reorganization Agreement.  Immediately after giving 
effect to the transactions contemplated by Section 6.15 of the Reorganization 
Agreement, the Company will have issued and outstanding 1,563,708 shares of 
Common Stock, 3,898,084 shares of Series A Preferred Stock, and 2,009,530 
shares of Series B Preferred Stock. All outstanding shares of Company Capital 
Stock are (and any shares issued pursuant to the transactions contemplated by 
Section 6.15 of the Reorganization Agreement will be) duly authorized, 
validly issued, fully paid, and non-assessable and not subject to preemptive 
rights created by statute, the Certificate of Incorporation or Bylaws of the 
Company or any agreement or document to which the Company is a party or by 
which it is bound.  Each outstanding share of Company Preferred Stock is 
presently convertible into one share of Company Common Stock.  Except as 
described in Schedule 2.2(b) or Schedule 2.2(c) of the Reorganization 
Agreement, there are no options, warrants, calls, rights, commitments or 
agreements of any character, written or oral, to which the Company is a party 
or by which it is bound obligating the Company to issue, deliver, sell, 
repurchase or redeem, or cause to be issued, delivered, sold, repurchased or 
redeemed, any shares of Company Capital Stock. 

         2.3  Of the 1,563,708 shares of Company Common Stock outstanding, all
shares were issued pursuant to restricted stock purchase agreements granting
repurchase options in favor of the Company in the event of a termination of
employment ("Restricted Stock").  Schedule 2.2(b) of the Reorganization
Agreement identifies each employee of the Company or any Subsidiary who holds
Restricted Stock and specifies the vesting schedule for such Restricted Stock,
the extent to which such shares of Restricted Stock are vested to date, and
whether the vesting of such Restricted Stock will accelerate as a result of the
transactions contemplated by this Agreement.
    
         2.4  The Company has reserved 1,000,000 shares of Common Stock for
issuance to employees and consultants pursuant to the Option Plan, of which
511,858 shares are subject to outstanding, unexercised options and 488,142
shares remain available for future grant.  Schedule 2.2(c) of the Reorganization
Agreement sets forth for each outstanding Company Option the name of the holder
of such option, the address of such holder, the number of shares of Common Stock
subject to such 


                                        -2-
<PAGE>


option, the exercise price and the vesting schedule of such option, including 
the extent vested to date, and whether the exercisability of such option will 
be accelerated and become exercisable by the transactions contemplated by 
this Agreement.  Except as described in Schedule 2.2(c), there are no 
options, warrants, calls, rights, commitments or agreements of any character, 
written or oral, to which the Company is a party or by which it is bound 
obligating the Company to grant, extend, accelerate the vesting of, change 
the price of, otherwise amend or enter into any such option, warrant, call, 
right, commitment, or agreement.  The holders of Company Options or any other 
options or rights set forth in Schedule 2.2(c) have been or will be given, or 
shall have properly waived, any required notice prior to the Merger.

         2.5  As a result of the Merger, Parent will be the record and sole 
beneficial owner of all outstanding Company Capital Stock and all rights to 
acquire or receive Company Capital Stock.  At or before the Effective Time, 
any rights of any holder or prospective holder of the Company's securities to 
cause such securities to be registered under the United States Securities Act 
of 1933, as amended (the "Securities Act"), and any information rights, 
voting rights, rights of co-sale, rights to maintain equity percentage, 
rights of first refusal and the like that may exist for the benefit of any 
such holder or prospective holder shall have been terminated, except as 
expressly contemplated by this Agreement.

    3.   CLOSING CERTIFICATE.  The Selling Stockholders shall deliver to
Parent on the Closing Date a certificate (the "Closing Certificate") setting
forth each Selling Stockholder's representations and warranties that each of the
representations and warranties set forth in Section 2 is accurate in all
respects as of Closing Date as if made on the Closing Date.

    4.   INDEMNIFICATION BY THE SELLING STOCKHOLDERS.

         4.1  Each Selling Stockholder, severally in proportion to the amount 
of Parent Common Stock set forth opposite his, her, or its name on SCHEDULE A 
hereto, but not jointly, shall hold harmless and indemnify each of the 
Indemnitees from and against, and shall compensate and reimburse each of the 
Indemnitees for, any Losses (as defined in Section 4.3) which are suffered or 
incurred by any of the Indemnitees or to which any of the Indemnitees may 
otherwise become subject at any time only to the extent (i) such Losses 
relate to a third-party claim and (ii) arise from or as a result of, or are 
connected with any fraudulent knowing or intentional breach of or inaccuracy 
in, or any knowing or intentional misrepresentation made with respect to, any 
of the representations and warranties made by such Selling Stockholder in 
Section 2 of this Agreement or in the Closing Certificate (each such breach a 
"Specified Breach").  A Selling Stockholder required to indemnify an 
Indemnitee under this Section 4.1 shall be referred to as an "Indemnifying 
Selling Stockholder."

         4.2  The term "Indemnitees" shall mean: (a) Parent; (b) each direct
and indirect subsidiary of Parent (including the Company); (c) the respective
officers and directors of each of the entities referred to in clauses "(a)" and
"(b)" of this Section 4.2; and (d) the respective successors and assigns of each
of the entities and persons referred to in clauses "(a)" through "(c)" of this
Section 4.2; PROVIDED, HOWEVER, that (i) no Indemnitee shall be entitled to
exercise any rights as an Indemnitee prior to the Effective Time and (ii)
neither of the Selling Stockholders nor any other officers or directors of the
Company prior to the Effective Time shall be deemed to be "Indemnitees."


                                        -3-
<PAGE>

         4.3  The term "Losses" shall include any loss, damage, injury,
liability, claim, demand, settlement, judgment , award, fine, penalty, Tax, fee
(including any legal fee, expert fee, accounting fee or advisory fee), charge,
cost (including any cost of investigation) or expense of any nature.

         4.4  The Selling Stockholders acknowledge and agree that, if there is
a Specified Breach and an Indemnitee shall recover any Losses pursuant to this
Indemnity Agreement resulting therefrom, then Parent itself shall be deemed, by
virtue of its ownership of common stock of the Company, to have incurred Losses
as a result of such Specified Breach.

         4.5  Each Indemnifying Selling Stockholder waives, and acknowledges
and agrees that such Indemnifying Selling Stockholder shall not have and shall
not exercise or assert or attempt to exercise or assert, any right of
contribution or right of  indemnity or any other right or remedy against the
Company or any other Selling Stockholder in connection with any indemnification
obligation or any other liability to which such Indemnifying Selling Stockholder
may become subject under this Indemnity Agreement.

         4.6  In the event of the assertion or commencement by any Person of
any claim or Legal Proceeding (whether against the Company, against any other
Indemnitee or against any other Person) with respect to which any of the Selling
Stockholders may become obligated to indemnify, hold harmless, compensate or
reimburse any Indemnitee pursuant to this Section 4, Parent shall be entitled to
defend such claim or Legal Proceeding.  In connection with the defense of such
claim:

         (a)  the Selling Stockholders shall make available to Parent any
    documents and materials in the possession or control of  any of the Selling
    Stockholders that may be necessary to the defense of such claim or Legal
    Proceeding;

         (b)  Parent shall keep the Selling Stockholders informed of all
    material developments and events relating to such claim or Legal Proceeding
    and shall permit the Selling Stockholders, at their own expense, to
    participate in the defense thereof; and

         (c)  Parent shall have the right to settle, adjust or compromise such
    claim or Legal Proceeding; PROVIDED, HOWEVER, that any such settlement,
    adjustment or compromise, if entered into without the consent of the
    Selling Stockholders (which consent shall not be unreasonably withheld),
    shall not be deemed to be conclusive of any Specified Breach or amount of
    Losses related thereto.

         4.7  No Indemnitee (other than Parent or any successor thereto or
assign thereof) shall be permitted to assert any indemnification claim or
exercise any other remedy under this Indemnity Agreement unless Parent (or any
successor thereto or assign thereof) shall have consented to the assertion of
such indemnification claim or the exercise of such other remedy.

         4.8  Parent (and any permitted Indemnitee in accordance with Section
4.7 above) shall have the right, at its election and in its sole discretion, to
seek recourse for any Losses hereunder either through the Escrow Fund or through
the provisions of this Indemnity Agreement, or both, and a claim 


                                        -4-
<PAGE>


by Parent (and any permitted Indemnitee in accordance with Section 4.7 above) 
initially through one avenue of recourse shall not preclude a later claim by 
Parent (and any permitted Indemnitee in accordance with Section 4.7 above) 
through the other, nor through any other avenue of legal or equitable relief 
available to Parent, subject to the requirements of Section 4.9 below.

         4.9  The scope and nature of the rights of the Indemnitees hereunder
shall be subject to the following:

              (i)    Any claim or Legal Proceeding hereunder must be asserted 
on or before 5:00 p.m. (California Time) on the date that is one year 
following the Closing Date.

              (ii)   No claim or Legal Proceeding hereunder may be asserted 
unless and until Parent has identified Losses, the aggregate amount of which 
exceed $75,000 (of which no individual Loss shall be less than $5,000), 
whether pursuant to the Escrow Agent in accordance with the provisions of 
Article VIII of the Reorganization Agreement or in writing to the Selling 
Stockholders pursuant hereto, in which event Parent may thereupon recover all 
Losses, without regard to the $75,000 limitation (or the $5,000 limitation in 
respect of any individual Loss).

              (iii)  In the event Indemnitees seek recourse for Losses 
through the provisions of this Indemnity Agreement, such recourse shall not 
limit the liability of the Indemnifying Selling Stockholders under the 
provisions of Article VIII of the Reorganization Agreement.

              (iv)   Any assertion of a claim for Losses through the delivery 
to the Escrow Agent of an Officer's Certificate in accordance with the 
provisions of Article VIII of the Reorganization Agreement shall be 
sufficient for the assertion of a claim or Legal Proceeding under this 
Indemnity Agreement.

              (v)    Any of the parties hereto may demand arbitration of any 
claim or Legal Proceeding initiated hereunder unless the amount of the damage 
or loss is at issue in pending litigation with a third party, in which event 
arbitration shall not be commenced until such amount is ascertained or Parent 
and Selling Stockholders holding a majority of the originally issued Parent 
Common Stock agree to arbitration; and in either such event the matter shall 
be settled by arbitration conducted in accordance with the provisions of 
Section 8.2(f)(ii) and the first sentence of Section 8.2(f)(iii).

              (vi)   Any decision or award as a result of such arbitration 
shall include the assessment of costs, expenses and reasonable attorneys' 
fees payable to the prevailing party in any such arbitration.               

              (vii)  Not withstanding anything to the contrary set forth in 
this Agreement, the  liability of each Indemnifying Selling Stockholder under 
this Indemnity Agreement shall not exceed the number of shares of Peregrine 
Common Stock to which the Indemnifying Selling Stockholder is entitled under 
Section 1.6(b) of the Reorganization multiplied by $15.25.

    5.   GENERAL.

         5.1  Except as specifically set forth herein, nothing in this 
Indemnity Agreement is intended to limit any of Parent's or the Selling 
Stockholders' rights, or any obligation of any Selling Stockholder, or of 
Parent under the Reorganization Agreement (or any agreement entered into in 
connection with the transactions contemplated by the Reorganization 
Agreement).

         5.2  This Indemnity Agreement shall be governed by and construed in 
accordance with the laws of the State of California.

         5.3  No party hereto may assign any of its rights or obligations 
hereunder without the prior written consent of the other party hereto.  This 
Indemnity Agreement will be binding upon and inure to the benefit of the 
parties hereto and their respective successors and permitted assigns.

         5.4  If any provision of this Indemnity Agreement, or the 
application thereof, is for any reason and to any extent invalid or 
unenforceable, the remainder of this Indemnity Agreement and application of 
such provision to other persons or circumstances will be interpreted so as 
reasonably to effect the intent of the parties hereto.  The parties further 
agree to replace such void or unenforceable provision of this Indemnity 
Agreement with a valid and enforceable provision that will achieve, to the 
greatest extent possible, the economic, business and other purposes of the 
void or unenforceable provision.

         5.5  This Indemnity Agreement may be executed in any number of 
counterparts, each of which shall be deemed to be an original and all of 
which shall constitute one and the same instrument.  This Indemnity Agreement 
will become binding when one or more counterparts thereof, individually or 
taken together, bear the signatures of all the parties reflected hereon as 
assignatories.

         5.6  Any term or provision of this Indemnity Agreement may be amended,
and the observance of any term of this Indemnity Agreement may be waived (either
generally or in a particular instance and either retroactively or prospectively)
only by a writing signed by the party to be bound thereby.  Notwithstanding any
rights that may be created in any third party under the terms of this Indemnity
Agreement, no such amendment or waiver will require the consent of such third
party to be effective.  The waiver by a party of any breach hereof or default in
the performance hereof will not be deemed to constitute a waiver of any other
default or any succeeding breach or default.

         5.7  Any request, communication, or other notice required or permitted
hereunder shall be in writing and shall be deemed to have been duly given if
sent by facsimile or delivered by recognized overnight or international courier
service or personal delivery (as the situation may require) at the respective
address or facsimile number of the party receiving notice as set forth below. 
Any party hereto may by notice so given change its address or facsimile number
for future notice hereunder.  All such notices and other communications
hereunder shall be deemed given (i) upon confirmation of delivery, 


                                        -6-

if sent by facsimile and (ii) upon delivery, if sent by recognized overnight

contemplated hereby and to carry into effect the intents and purposes of this

or any other rights of any kind in any client, customer, affiliate, 
stockholder or partner of any party hereto or any other person or entity 
unless specifically provided otherwise herein, and, except as so provided, 
all provisions hereof will be personal solely between the parties of this

<PAGE>

                                   EXHIBIT H

                FORM OF LEGAL OPINION OF THE VENTURE LAW GROUP


    1.   The Company is a corporation duly organized, validly existing, and 
in good standing under the laws of the State of Delaware, and Apsylog (the 
"Subsidiary") is a corporation duly organized, validly existing, and in good 
standing under the laws of the State of California. The Company and the 
Subsidiary each has the corporate power and authority to own, lease, and 
operate its assets and property and to carry on its business as now being 
conducted and is duly qualified or licensed to do business and is in good 
standing in each jurisdiction where the character of the properties owned, 
leased, or operated by it or the nature of its activities makes such 
qualification or licensing necessary, except where the failure to be so 
qualified would not have a Material Adverse Effect on the Company or the 
Subsidiary.

    2.   The authorized Company Capital Stock consists of 15,000,000 shares 
of authorized Common Stock, par value $0.001 per share, of which 
[_____________]shares are issued and outstanding, and 10,000,000 shares of 
authorized Preferred Stock, par value $0.001 per share. Of the authorized 
Preferred Stock, 3,898,084 shares have been designated as Series A Preferred 
Stock, of which [___________]shares are issued and outstanding, and 2,009,530 
shares have been designated as Series B Preferred Stock, of which 
[____________] shares are issued and outstanding. All outstanding shares of 
Company Capital Stock are duly authorized, validly issued, fully paid, and 
non-assessable and not subject to preemptive rights created by statute, the 
Certificate of Incorporation or Bylaws of the Company or any agreement or 
document to which the Company is a party or by which it is bound. Each 
outstanding share of Company Preferred Stock is presently convertible into 
one share of Company Common Stock. Except as described in the Agreement, to 
our knowledge, there are no options, warrants, calls, rights, commitments or 
agreements of any character, written or oral, to which the Company is a party 
or by which it is bound obligating the Company to issue, deliver, sell, 
repurchase or redeem, or cause to be issued, delivered, sold, repurchased or 
redeemed, any shares of Company Capital Stock. The Company has reserved 
[_____________] shares of Common Stock for issuance to employees and 
consultants pursuant to the Option Plan, of which [_____________] shares are 
subject to outstanding, unexercised options and [_____________] shares remain 
available for future grant.  

    3.   All of the outstanding shares of the capital stock of each 
Subsidiary have been duly authorized and validly issued, are fully paid and 
nonassessable, and are wholly owned by Apsylog S.A.  Except as described in 
the Agreement, to our knowledge, there are no options, warrants, calls, 
rights, commitments or agreements which the Subsidiary is a party or by which 
the Subsidiary is bound, obligating the Subsidiary to issue, deliver, sell, 
repurchase or redeem, or cause to be issued, delivered, sold, repurchased or 
redeemed, any shares of such Subsidiary's capital stock.

    4.   At or before the Effective Time, to our knowledge, any rights of any 
holder or prospective holder of the Company's securities to cause such 
securities to be registered under the 

<PAGE>

Securities Act, and any information rights, voting rights, rights of co-sale, 
rights to maintain equity percentage, rights of first refusal and the like 
that may exist for the benefit of any such holder or prospective holder shall 
have been terminated, except as expressly contemplated by the Agreement.  

    5.   The Company has all requisite corporate power and authority to enter 
into the Agreement and to consummate the transactions contemplated thereby.  
The execution and delivery of the Agreement and the consummation of the 
transactions contemplated thereby have been duly authorized by all necessary 
corporate action on the part of the Company, its Board of Directors and its 
stockholders.  The vote required of the Company's stockholders to duly 
approve the Merger is a majority of the outstanding shares of Company Common 
Stock and a majority of the outstanding shares of Company Preferred Stock, 
each voting as a separate class. The Agreement has been duly executed and 
delivered by the Company and constitutes the valid and binding obligation of 
the Company, enforceable in accordance with its terms.  Except as set forth 
in the Agreement, the execution and delivery of the Agreement by the Company 
does not, and, as of the Effective Time, the consummation of the transactions 
contemplated hereby will not result in any violation of, or default under 
(with or without notice or lapse of time, or both), or give rise to a right 
of termination, cancellation or acceleration of any obligation or loss of any 
benefit under (any such event, a "CONFLICT") (i) any provision of the 
Certificate of Incorporation or Bylaws of the Company or the Subsidiary or 
(ii) any material contract or agreement listed in a schedule attached hereto 
or to our knowledge, any judgment, order, decree, statute, law, ordinance, 
rule or regulation applicable to the Company, the Subsidiary or their 
respective properties or assets.  No consent, waiver, approval, order, or 
authorization of, or registration, declaration or filing with, any court, 
administrative agency or commission or other federal, state, county, local or 
foreign governmental authority, instrumentality, agency or commission 
("GOVERNMENTAL ENTITY") or any third party (so as not to trigger any 
Conflict), is required by or with respect to the Company or the Subsidiary, 
in connection with the execution and delivery of this Agreement or the 
consummation of the transactions contemplated hereby, except for (i) the 
filing of the Certificate of Merger with the Delaware Secretary of State, 
(ii) such consents, waivers, approvals, orders, authorizations, 
registrations, declarations and filings as may be required under applicable 
federal and state securities laws and the laws of any foreign country, and 
(iii) such other consents, waivers, authorizations, filings, approvals, and 
registrations which if not obtained or made would not have a Material Adverse 
Effect on the Company or the Subsidiary.

    6.   Except as disclosed in the Agreement, to our knowledge, there is no 
action, suit, proceeding, claim, arbitration, or investigation pending before 
any court or administrative agency against the Company or any Subsidiary.

     4.   that the obligations of US Inc. and of the Affiliate

          We are rendering the opinions expressed below solely on
the basis and upon matters of French law and regulations.

          Based upon and subject to the foregoing, to any matter
not disclosed to us by the parties concerned, and to the
reservations and qualifications set forth below, and having regard
to such legal considerations as we deem relevant, we are of the
opinion that under the laws of the Republic of France as in effect
on the date hereof:

1.        Each of the Companies is a corporation duly organized,
validly existing under the laws of France.  Each of the Companies
has the corporate power and authority to own, lease, and operate
its assets and property.

2.        Except as set forth in the Agreement, all of the issued
shares of the capital stock of each of the Companies have been duly
authorized and validly issued and are fully paid.  To our
knowledge, none of the Companies has decided or authorized the
issue of options, warrants, convertible bonds or securities defined
in article 339-1 of the law no. 66-537 of July 24, 1966 on
commercial companies and none of the Companies has decided or
authorized the repurchase or the redemption of its own shares.


                                         -3-
<PAGE>

3.        APSYLOG  S.A. is, to our knowledge, the owner of 1,255
shares of AGDS out of the 2,500 shares of FF. 100 nominal value
each issued by AGDS.

4.        Except as set forth in the Agreement, no consent,
approval, authorization, order, registration, designation,
declaration, filing, qualification, license or permit of any French
court or any French public, governmental, administrative or
regulatory agency or body is required for the consummation by the
US Inc. of the transactions contemplated by the Agreement.

5.        Except as disclosed in the Agreement, and to our
knowledge, there is no action, suit, proceeding, claim or
arbitration pending before any court or administrative agency
against APSYLOG S.A. and AGDS.

6.        The Amendment has been duly executed by or on behalf of
the parties thereto and constitutes a legal, valid and binding
obligation of the parties thereto and is enforceable against the
parties thereto in accordance with its terms subject as to
enforcement, bankruptcy, insolvency, fraudulent transfer,
reorganisation, moratorium and similar laws of general
applicability relating to or affecting creditors' rights.

7.        Subject to full payment by APSYLOG S.A. of the price of
the 1,245 shares (the < < Shares > >) of AGDS to each one of the
selling party, subject to the remittance by each one of the selling
parties of the transfer forms as provided in the Amendment, and
subject to full compliance by the selling parties with the terms of
the Protocole du 2 avril 1996 and of the Amendment APSYLOG S.A.
will obtain good and valid title to the Shares.

          The opinions expressed above are subject to the following
reservations:

     (i)       where any party to the Amendment is vested with
               discretion, French law requires that such discretion
               is not abused;

     (ii)      any enforcement against any party to the Amendment
               may be limited by the provisions of French law
               giving discretionary powers to the French courts
               such as the discretion to limit or increase the
               amount of payments due under any penalty or
               indemnity clause which, taking into consideration
               the respective positions of the parties, is
               considered by such courts to be manifestly excessive
               or nominal, and such as the discretion to grant a
               grace period of up to two years or to reduce the
               rate of interest applicable to deferred payments;

     (iii)     we express no opinion as to the availability under
               French law or before a French court of the
               enforcement of a performance obligation or any other
               remedy other than those culminating in a judgement
               for the payment of money; and

     (iv) this opinion is subject to the application of any
          applicable bankruptcy, liquidation, winding-up,
          insolvency or similar laws affecting the rights of
          creditors generally.
