                      AGREEMENT AND PLAN OF REORGANIZATION


        Agreement and Plan of Reorganization, dated as of November 7, 1994, by
and among IMRS Inc., a Delaware corporation ("Parent"), IP Merger, Inc., a
California corporation and a wholly-owned subsidiary of Parent ("Merger Sub"),
and Pillar Corporation, a California corporation (the "Company"), and, with
respect to the matters set forth in Article VII hereof only, American Stock
Transfer and Trust Company (the "Indemnification Escrow Agent").


                                  ARTICLE I
                                      
                                  THE MERGER

        Section 1.1  THE MERGER.  Subject to the terms and conditions hereof,
and in accordance with the California General Corporation Law (the "CCL"),
Merger Sub will be merged with and into the Company (the "Merger"), as soon as
practicable following the satisfaction or waiver of the conditions set forth in
Article VI hereof.  Following the Merger, the Company shall continue as the
surviving corporation (the "Surviving Corporation"), and the separate corporate
existence of Merger Sub shall cease.

        Section 1.2  EFFECTIVE TIME.  The Merger shall become effective upon
the filing of a duly executed Agreement and Plan of Merger substantially in the
form of Exhibit A hereto (the "Agreement of Merger") and the required officers'
certificates (the "Officers' Certificates") with the Secretary of State of the
State of California (the date and time of such filing being hereinafter
referred to as the "Effective Time").

        Section 1.3  EFFECTS OF THE MERGER.  The Merger shall have the effects
set forth in Section 1107 of the CCL.  As of the Effective Time, the Company
shall be a wholly-owned subsidiary of Parent.  The Merger is intended to be a
reorganization within the meaning of Section 368(a)(2)(E) of the Internal
Revenue Code of 1986, as amended (the "Code").

        Section 1.4  ARTICLES OF INCORPORATION AND BY-LAWS.  The Articles of
Incorporation of the Surviving Corporation shall, at the Effective Time, be
amended so as to read in its entirety as attached to the Agreement of Merger as
Exhibit A thereto.  The By-laws of the Surviving Corporation shall, at the
Effective Time, be amended so as to read in its entirety as the By-laws of
Merger Sub as in effect immediately prior to the Effective Time.

        Section 1.5  DIRECTORS AND OFFICERS OF THE SURVIVING CORPORATION.  At
the Effective Time, each director of the Company shall cease to hold such
office, and the directors of the

   6

                                      -2-

Surviving Corporation shall be the following individuals, each of whom shall
hold such office until the next annual meeting of shareholders of the Surviving
Corporation and until his successor shall have been elected or appointed and
qualify to serve, or otherwise as provided in the Articles of Incorporation or
By-laws of the Surviving Corporation:


                    James Perakis
                    David Sample
                    Lucy Ricciardi

        At the Effective Time, the officers of Merger Sub immediately prior to
the Effective Time shall be the officers of the Surviving Corporation, in the
same capacity or capacities, to serve until his or her successor shall have been
duly elected and qualified to serve.

        Section 1.6  WRITTEN CONSENT OF THE SHAREHOLDERS OF THE COMPANY.  The
Company will take all action necessary in accordance with applicable law and its
Amended and Restated Articles of Incorporation and by-laws to solicit the
approval of this Agreement, the Merger and all the transactions contemplated
hereby, by all shareholders of the Company, by means of a Written Consent of
Shareholders (the "Company's Shareholders' Consent"). The Company shall use its
best efforts to obtain such shareholder approval.  The Company represents and
warrants that its Board of Directors, at a meeting duly called and held, has (i)
determined that the Merger is fair to and in the best interests of the
shareholders of the Company (the "Company Shareholders") and (ii) resolved to
recommend to the shareholders of the Company that they approve this Agreement,
the Merger and all the transactions contemplated hereby.

Section 1.7  CLOSING; CONSUMMATION OF THE MERGER.

        (a)  The closing of the transactions contemplated by this Agreement (the
"Closing") shall take place, subject to the provisions of Section 1.7(b), 
below: (a) at the offices of Testa, Hurwitz & Thibeault, 53 State Street,
Boston, Massachusetts 02109, on November 18, 1994, or (b) at such other date and
place as Parent and the Company may agree (but in no event later than November
30, 1994, in the case that such parties are unable to agree).  The date of the
Closing, determined pursuant to this Section 1.7, is hereinafter referred to as
the "Closing Date."  If all conditions set forth in Article VI hereof are
determined to be satisfied (or duly waived) at the Closing, as soon as
practicable the parties hereto will cause the Merger to be consummated by the
filing of the Agreement of Merger and Officers' Certificates with the Secretary
of State of the State of California, in such form as required by and executed in
accordance with the requirements of the CCL and the Closing shall be
consummated.

                                      -3-

        (b)  Notwithstanding Section 1.7(a) above, if the Closing shall not
occur by November 30, 1994, solely as a result of an inability to satisfy the
Closing condition contained in Section 6.3(j), then the Closing shall occur at
such date and place as Parent and the Company shall agree (but in no event later
than December 31, 1994).  In the event that the Closing still has not occurred
by December 31, 1994 solely because of the inability to satisfy Section 6.3(j),
Parent and the Company shall cooperate in the preparation of a Registration
Statement on Form S-4 under the Securities Act of 1933 pursuant to Section 5.14
hereof to be mailed to the Company's Shareholders in connection with the
approval of the transactions contemplated hereby and the Closing shall occur at
such date and place as Parent and the Company may agree after the completion of
the Company's shareholder solicitation (but in no event later than March 31,
1995, in the case that such parties are unable to agree).


                                   ARTICLE II

          CONVERSION OF SHARES; EXCHANGE OF SHARES; DISSENTING SHARES


Section 2.1  CONVERSION OF COMPANY SHARES.

        (a)  Subject, without limitation, to the provisions of Section 2.2
hereof, at the Effective Time all of the shares of common stock, $.001 par value
per share, of the Company (the "Company Common Shares") and all of the shares of
preferred stock, $.001 par value per share, of the Company (the "Company
Preferred Shares") (the Company Common Shares and the Company Preferred Shares
shall be collectively referred to as the "Company Shares") issued and
outstanding immediately prior to the Effective Time (excluding any Company
Shares held by Parent or Merger Sub or any other subsidiary of Parent or by the
Company, which shares shall be cancelled in the Merger and Dissenting Company
Shares (as defined in Section 2.2 hereof)) shall automatically, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into, on a pro rata basis, shares of common stock, $.01 par value per share, of
Parent (the "Parent Common Stock") based on the Conversion Ratio (as defined in
Section 2.1(c) below), and cash (rounded to the nearest whole cent) in lieu of
fractional shares, if any, pursuant to Section 2.4 below (such Parent Common
Stock and cash being referred to herein as the "Merger Consideration").  The
Company Shares that are actually issued and outstanding immediately prior to the
Effective Time are sometimes referred to herein as the "Outstanding Company
Shares."  Employee stock options and stock purchase rights, and any other
rights, warrants or options to acquire Company Shares and securities convertible
into Company Shares which are outstanding immediately prior to the Effective
Time and do not expire pursuant to their terms on
   8

                                      -4-

or before the Closing (each of which is specifically identified in Section 4.2
of the Company Disclosure Schedule (as defined  below), and are sometimes
referred to herein as the "Outstanding Company Options.")

        (b)  The maximum number of shares of Parent Common Stock to be issued
(which maximum number includes Parent Common Stock to be reserved for issuance
upon exercise of the Outstanding Company Options assumed by Parent) in exchange
for the acquisition of all outstanding Company Common Shares, Company Preferred
Shares and assumption of all Outstanding Company Options, shall be 607,297,
provided that such maximum number shall be adjusted to the extent required by
Sections 2.1(c) and 2.5 herein.

        (c)  The ratio at which one outstanding Company Share will be converted
into shares of Parent Common Stock at the Effective Time is herein called the
"Conversion Ratio" and shall be calculated as set forth in this Section 2.1(c). 
At the Effective Time, each Outstanding Company Share shall be converted into
the right to receive that number (which may be a fraction) of shares of Parent
Common Stock that equals the quotient obtained by dividing 607,297 (as may be
adjusted, the "Numerator") by the sum of (A) the number of outstanding Company
Shares immediately prior to the Effective Time and (B) the number of Company
Shares issuable (without giving effect to any vesting provisions) upon the
exercise of Outstanding Company Options immediately prior to the Effective Time;
PROVIDED, however, that if the Average Price (as defined below) is greater than
$34.00 per share of Parent Common Stock, then the Numerator shall be adjusted to
a number equal to (i) the Transaction Value (as defined herein) divided by (ii)
the Average Price (subject to a possible further adjustment pursuant to the
second paragraph of this subsection (c) below).  The "Transaction Value" shall
equal the sum of (A) $20,648,100 and (B) a number equal to 607,297 multiplied by
one-half of the difference between the Average Price and $34.00.  Each holder of
Company Shares shall have the right to receive that aggregate number of shares
of Parent Common Stock equal to the foregoing quotient multiplied by the number
of Company Shares held by such holder immediately prior to the Effective Time,
subject to Section 2.4 herein.  "Average Price" means the average (rounded to
the nearest penny), for the six (6) consecutive trading days ending on and
including the second trading day preceding the Closing Date, of the last
reported sale price of shares of Parent Common Stock on The Nasdaq Stock
Market's Nasdaq National Market ("NNM").

        In the event that the Closing takes place at any time after December 31,
1994, and Parent shall not have delivered the Special Notice (as defined in
Section 5.17) to the Indemnification Escrow Agent pursuant to Section 5.17, then
the Numerator shall be reduced (in addition to any reduction in the Numerator
pursuant to the foregoing paragraph) by that number of
   9

                                      -5-

shares of Parent Common Stock which is equal to the number calculated by        
dividing $1,500,000 by the Average Price.

        By way of example and illustration only:  (i) if the Closing were to
occur on January 2, 1995 and the Average Price calculated for such date were
$38.00, and Parent shall not have delivered the Special Notice to the
Indemnification Escrow Agent pursuant to Section 5.17, then the Numerator would
be calculated as follows:

[(20,648,100) + (50% x 4)(607,297)]  -  (1,500,000)
- -----------------------------------     -----------
               38                           38       =  535,860.37

(ii) If the facts from example (i) were true, except that the Average Price
were $32.00, then the Numerator would be calculated as follows:

        607,297 - (1,500,000)
                  -----------
                       38      = 567,824

        (d)  At the Effective Time, each Company Share held by the Company shall
automatically, by virtue of the Merger, be cancelled without payment of any
consideration therefor and without any conversion thereof.

        (e)  At the Effective Time, each Company Share held by Parent or Merger
Sub or any other subsidiary of Parent shall automatically, by virtue of the
Merger, be cancelled without payment of any consideration therefor and without
any conversion thereof.

        (f)  At the Effective Time, each share of common stock, no par value per
share, of Merger Sub issued and outstanding immediately prior to the Effective
Time shall, by virtue of the Merger and without any action on the part of the
holder hereof, be converted into and exchangeable for one share of common stock,
no par value per share, of the Surviving Corporation.

        (g)  At the Effective Time, Parent shall assume in accordance with
Section 425(a) of the Internal Revenue Code and the regulations promulgated
thereunder the Company's rights and obligations with respect to each Outstanding
Company Option issued under the Company's 1988 Stock Option Plan and 1992 Long-
Term Equity Incentive Plan (together, the "Option Plans") and each holder shall
thereby be entitled to acquire on substantially the same terms (including the
dates and extent of exercisability) and subject to substantially the same
conditions as such option, the number of shares of Parent Common Stock
determined by multiplying the number of Company Shares subject to such option
immediately prior to the Effective Time by the Conversion Ratio (rounded down to
the nearest whole share), at an exercise price per share of Parent Common Stock
(rounded up to the nearest whole cent) determined by dividing the exercise price
per Company Share
   10

                                      -6-

of such option immediately prior to the Effective Time by the Conversion
Ratio.

        (h)  At the Effective Time, Parent shall assume in accordance with the
provisions thereof, those Outstanding Company Options not assumed by Parent
under Section 2.1(g) and each holder thereof shall thereby be entitled to
acquire on substantially the same terms (including the dates and extent of
exercisability) and subject to substantially the same conditions as such
security, the number of shares of Parent Common Stock determined by multiplying
the number of Company Shares subject to such security immediately prior to the
Effective Time by the Conversion Ratio (rounded down to the nearest whole
share), at an exercise price per share of Parent Common Stock (rounded up to the
nearest whole cent) determined by dividing the exercise price per Company Share
of such security immediately prior to the Effective Time by the Conversion
Ratio.

        Section 2.2  DELIVERY OF MERGER CONSIDERATION.

        (a) Promptly after the Effective Time, Parent, on behalf of the
Surviving Corporation, shall deposit with American Stock Transfer & Trust
Company, as Exchange Agent (the "Exchange Agent"), in trust for Company
Shareholders, the certificates representing the shares of Parent Common Stock
and the cash (in immediately available funds) to which holders of Outstanding
Company Shares shall be entitled pursuant to Section 2.1 hereof.

        (b) Promptly after the Effective Time, each holder of record (other than
Parent or Merger Sub or any other subsidiary of Parent) of a certificate or
certificates which immediately prior to the Effective Time represented issued
and outstanding Company Shares (individually a "Certificate" and collectively
the "Certificates") shall deliver to the Exchange Agent such shareholder's
Certificates.  Upon surrender by a holder of Outstanding Company Shares of a
Certificate or Certificates for cancellation to the Exchange Agent or of a lost
certificate indemnity agreement with respect thereto and any other documentation
required by the Exchange Agent or Parent's transfer agent, the holder of such
Certificate(s) shall be entitled to receive in exchange therefor all of the
shares of Parent Common Stock (excluding those shares being placed in escrow)
and all the cash, if any, that such holder is entitled to receive pursuant to
Section 2.1 hereof.  Of the shares otherwise issuable to the Shareholders, an
aggregate number of shares equal to the sum of (i) 10% of the maximum number of
shares of Parent Common Stock issuable to the Company Shareholders hereunder
(the "Indemnification Escrow Shares") and (ii) an aggregate number of shares
equal to $1,500,000 divided by the Average Price (the "Special Escrow Shares")
(PROVIDED, HOWEVER, that in the event that the Numerator is adjusted pursuant to
the terms of the second paragraph of Section 2.1(c), the number of Special
Escrow Shares shall be zero) shall be transferred from the Exchange
   11

                                      -7-

Agent referred to in Section 2.2(a) to the Indemnification Escrow Agent, to be
held in escrow pursuant to Article VII hereof and disposed of by the
Indemnification Escrow Agent in accordance with the terms and provisions of
Article VII hereof.  The delivery of the Indemnification Escrow Shares and the
Special Escrow Shares (if any) shall be made on behalf of the Company
Shareholders in accordance with the provisions hereof, with the same force and
effect as if such shares had been delivered by Parent directly to such holders
and subsequently delivered by such holders to the Indemnification Escrow Agent. 
The shares so deposited shall be evidenced by separate certificates in the names
of the Company Shareholders and shall not be assignable or transferable except
as provided in Article VII hereof.  B.J. Cassin has been selected by the Company
Shareholders as the initial representative of the Company Shareholders (the
"Indemnification Representative") and, in the event of the inability or
unwillingness prior to the execution of the Indemnification Escrow Agreement of
B.J. Cassin to act as Indemnification Representative, a substitute
Indemnification Representative will be similarly selected.  Such Indemnification
Representative is authorized by this Agreement, as a specific term of the Merger
provided for herein, to act as Indemnification Representative of the Company
Shareholders in accordance with the provisions hereof, with the powers and
authority provided for in Article VII hereof.  The adoption of this Agreement by
the Company Shareholders shall also constitute their approval of the terms and
provisions of Section 5.17 and Article VII, including the indemnification
provided for therein, their confirmation of the appointment of American Stock
Transfer & Trust Company to act as Indemnification Escrow Agent, and their
approval of the terms and provisions herein relating to the Indemnification
Representative, including the provisions relating to the appointment of
replacements, and their confirmation of the appointment of B.J. Cassin to act as
the initial Indemnification Representative.

        (c)  Until surrendered, each Certificate shall, after the Effective
Time, represent only the right to receive shares of Parent Common Stock and the
right to receive cash into which the Company Shares formerly represented thereby
shall have been converted pursuant to Section 2.1 hereof.  Any dividends or
other distribution declared after the Effective Time with respect to Parent
Common Stock shall be paid to the holder of any Certificate when the holder
thereof surrenders such Certificate.

        (d)  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
   12

                                      -8-

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.

        (e)  Any funds or Parent Common Stock remaining with the Exchange Agent
upon the publication of Parent's audited financial statements for the year ended
June 30, 1995 shall be released and repaid by the Exchange Agent to the
Surviving Corporation, after which time persons entitled thereto may look,
subject to applicable escheat laws and other similar laws, only to the Surviving
Corporation for the payment thereof.  Notwithstanding anything to the contrary
in this Section 2.2, 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 Shares for any amount properly paid to a public official pursuant to
applicable escheat or similar laws.

        (f)  After the Effective Time there shall be no transfers on the stock
transfer books of either the Company (the stock transfer books of which shall be
closed) or the Surviving Corporation of the Company Shares which were
outstanding immediately prior to the Effective Time.  If, after the Effective
Time, Certificates are presented for transfer to the Exchange Agent or the
Surviving Corporation, they shall be cancelled and exchanged for the Merger
Consideration as provided in this Article II.

        Section 2.3  DISSENTING COMPANY SHARES.  Company Shares for which the
Company's Shareholders' Consent has not been executed and delivered and with
respect to which a demand for payment and appraisal shall have been properly
made in accordance with the CCL ("Dissenting Company Shares") shall not be
converted into the right to receive the Merger Consideration at or after the
Effective Time unless and until the holder of such Company Shares withdraws his
or her demand or becomes ineligible for such payment and appraisal.  If a holder
of Dissenting Company Shares shall withdraw his or her demand for such payment
and appraisal or shall become ineligible for such payment and appraisal, then,
as of the Effective Time or the occurrence of such event of withdrawal or
ineligibility, whichever last occurs, such holder's Dissenting Company Shares
shall cease to be Dissenting Company Shares and shall be converted into the
right to receive, and shall be exchangeable for, the Merger Consideration into
which such Dissenting Company Shares would have been converted pursuant to
Section 2.1 hereof.

        Section 2.4  NO FRACTIONAL SHARES.  No certificates or scrip for
fractional shares of Parent Common Stock will be issued, no Parent stock split
or dividend shall be paid in respect of any fractional share interest, and no
such fractional shares interest shall entitle the owner thereof to vote or to
any rights of or as
   13

                                      -9-

a stockholder of Parent.  In lieu of such fractional shares, any holder of
Company Shares 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) will be paid the cash value of such
fraction, which shall be equal to the fraction multiplied by a dollar amount
equal to (i) the Transaction Value divided by 607,297 if the Average Price is
greater than $34.00 per share or (ii) the Average Price in all other cases.

        Section 2.5  ADJUSTMENTS.  If, between the date hereof and the Effective
Time, all outstanding shares of Parent Common Stock shall be changed into a
different number of shares or a different class by reason of any
reclassification, recapitalization, split- up, exchange of shares or
readjustment, or if a stock dividend thereon shall be declared with a record
date within such period, the number of shares of Parent Common Stock to be
issued and delivered in the Merger for each outstanding Company Share as
provided in this Agreement shall be correspondingly adjusted.


                                  ARTICLE III

            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

        Except as set forth in the disclosure letter of Parent dated as of the
date hereof and delivered herewith to the Company (the "Parent Disclosure
Schedule") (it being agreed that (i) any item set forth in the Parent Disclosure
Schedule having relevance to more than one of the following sections of this
Agreement shall be recited in full or cross-referenced in each corresponding
section of the Parent Disclosure Schedule and (ii) the term "Material Adverse
Effect," as used in this Article III, shall mean a material adverse effect on
the business, assets, condition (financial or otherwise) or result of operations
of Parent and its subsidiaries taken as a whole), Parent and Merger Sub
represent and warrant to the Company as follows:

        Section 3.1  ORGANIZATION AND QUALIFICATION.  Each of Parent and Merger
Sub is a corporation duly organized, validly existing and in good standing under
the laws of its jurisdiction of incorporation and has the requisite corporate
power and all material governmental licenses, authorizations, consents and
approvals required to carry on its business as it is now being conducted. 
Parent is duly qualified as a foreign corporation to do business, and is in good
standing, in each jurisdiction where the character of its properties owned or
leased or the nature of its activities makes such qualification necessary,
except where the failure to be so qualified will not have, individually or in
the aggregate, a Material Adverse Effect.

        Section 3.2  CAPITALIZATION.  The authorized capital stock of Parent
consists of 1,000,000 shares of preferred stock, $.01 par
   14

                                     -10-

value per share, of which no shares are issued or outstanding or held in
Parent's treasury, 15,000,000 shares of Parent Common Stock, of which, as of
September 30, 1994, (a) 7,201,651 shares were validly issued and
outstanding, fully paid and nonassessable, (b) 2,160,420 shares were held in
Parent's treasury and (c) 2,841,995 shares were reserved for issuance pursuant
to Parent's stock option and stock purchase plans for its employees and
directors.  Except as set forth in the Parent Disclosure Schedule, there are no
options, warrants or other rights, agreements or commitments (contingent or
otherwise) obligating Parent to issue shares of its capital stock or any other
securities convertible into or evidencing the right to subscribe to shares of
its capital stock.

        Section 3.3  AUTHORITY RELATIVE TO THIS AGREEMENT.  Each of Parent and
Merger Sub has the requisite corporate power and authority to enter into this
Agreement and to carry out its obligations hereunder.  The execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby have been duly authorized by the respective Boards of Directors of Parent
and Merger Sub, and no other corporate proceedings on the part of Parent or
Merger Sub are necessary to authorize this Agreement and the transactions
contemplated hereby.  This Agreement has been duly and validly executed and
delivered by each of Parent and Merger Sub and, assuming this Agreement
constitutes a valid and binding obligation of the Company and the Company
Shareholders, this Agreement constitutes a valid and binding agreement of each
of Parent and Merger Sub enforceable against each of Parent and Merger Sub in
accordance with its terms, except as the enforceability hereof may be subject to
or limited by bankruptcy, insolvency, reorganization, arrangement or similar
laws affecting the rights of creditors generally, judicial limitations upon the
specific performance of certain types of obligations and public policy.

        Section 3.4  NON-CONTRAVENTION.  Neither Parent nor Merger Sub is
subject to or obligated under any charter, by-law or contract provision or any
license, franchise or permit, or any order, writ, injunction, decree, statute,
rule or regulation which would be breached or violated or in respect of which a
right of acceleration would be created by its executing and carrying out this
Agreement, other than any such breach, violation or right which (a) will not
have, individually or in the aggregate, a Material Adverse Effect.  or (b) will
be cured, waived or terminated prior to the Effective Time.

        Section 3.5  REPORTS AND FINANCIAL STATEMENTS.  Parent has previously
furnished to the Company true and correct copies of its (i) Form 10-K for the
period ended June 30, 1994, (ii) its Quarterly Reports on Form 10-Q for the
periods ended September 30, 1993, December 31, 1993 and March 31, 1994 and (iii)
all other reports or registration statements filed by it with the U.S.
Securities and Exchange Commission (the
   15

                                     -11-

"Commission") under the Exchange Act since January 1, 1994 all in the form
(including exhibits) so filed (collectively, the "REPORTS").  As of their
respective dates, the Reports complied in all material respects with the then
applicable published rules      and regulations of the Commission with respect
thereto at the date of their issuance and did not contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.  As of the date
hereof, no additional filings or amendments to previously filed Reports are
required pursuant to such rules and regulations.  Each of the audited
consolidated financial statements and unaudited interim financial statements
included in Parent's Reports has been prepared in accordance with generally
accepted accounting principles applied on a consistent basis (except as may be
indicated therein or in the notes thereto) and fairly presents the financial
position of the entity or entities to which it relates as at its date or the
results of operations, stockholders equity or cash flows, subject to normal
year-end adjustments and any other adjustments described therein, which
adjustments will not be material in amount or effect.

        Section 3.6  VALIDITY OF PARENT COMMON STOCK.  The shares of Parent
Common Stock to be issued in the Merger will, when issued, be validly issued,
fully paid and nonassessable.

        Section 3.7  CONSENTS AND APPROVALS OF GOVERNMENTAL AUTHORITIES. 
Except for (a) the requirements of state securities (or "Blue Sky") laws, (b)
the filing and recording of appropriate documents as provided by the laws of the
State of California, (c) the filing of appropriate documents with the NNM and
(d) the filing of a Form D with the United States Securities and Exchange
Commission, if applicable, no consent, approval or authorization of, or
declaration, filing or registration with, any governmental or regulatory
authority is required to be made or obtained by Parent or Merger Sub in
connection with the execution, delivery and performance of this Agreement or the
consummation of the transactions contemplated hereby.

        Section 3.8  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since June 30, 1994,
there has not been any material adverse change in the business, assets,
condition (financial or otherwise), result of operations or prospects of Parent
and its subsidiaries, taken as a whole.

        Section 3.9  ACCURACY OF INFORMATION.  The Reports, the information
supplied by Parent for inclusion in the information statement to be sent to the
Company Shareholders in connection with the consideration and approval of the
Merger, this Agreement and the transactions contemplated hereby, and all other
certificates, documents and instruments furnished by the Company (or any of its
directors, officers or employees) in connection with this Agreement or the
Merger, or any other transaction
   16

                                     -12-

contemplated by this Agreement, and represented as being so furnished, are true
and correct, and, when taken as a whole, do not contain any untrue statement of
a material fact or knowingly omit to state any material fact necessary in
order to make the statements included herein or therein, in light of the
circumstances under which they were made, not misleading. Notwithstanding the
foregoing, Parent makes no representation or warranty with respect to any
information supplied by the Company or any of the Company Shareholders or their
affiliates which is contained in any of the foregoing documents.


                                  ARTICLE IV
                                       
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

        Except as set forth in the disclosure schedules of the Company dated as
of the date hereof and delivered herewith to Parent (the "Company Disclosure
Schedule") (it being agreed that (i) any item set forth in the Company
Disclosure Schedule having relevance to more than one of the following sections
of this Agreement shall be recited in full or cross-referenced in each
corresponding section of the Company Disclosure Schedule, (ii) the term
"Material Adverse Effect," as used in this Article IV, shall mean a material
adverse effect on the business, assets, condition (financial or otherwise) or
result of operations of the Company, and (iii) the term "Material Adverse
Change," as used in this Article IV shall mean a material adverse change in the
business, assets, condition (financial or otherwise) or result of operations of
the Company), the Company represents and warrants to Parent and Merger Sub as
follows:

        Section 4.1  ORGANIZATION AND QUALIFICATION.  The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of California and has the requisite corporate power and all
material governmental licenses, authorizations, consents and approvals required
for the ownership and operation of its properties and the carrying on of its
business as it is now being conducted and as it is now proposed to be conducted
through the Closing.  The Company is duly qualified as a foreign corporation to
do business, and is in good standing, in each jurisdiction where the character
of its properties owned or leased or the nature of its activities makes such
qualification necessary, except where the failure to be so qualified will not,
individually or in the aggregate, have a Material Adverse Effect.

        Section 4.2  CAPITALIZATION.  As of the date hereof, the authorized
capital stock of the Company is as set forth on Section 4.2 of the Company
Disclosure Schedule.  As of the date hereof, no Company Common Shares and no
Company Preferred Shares are held in the Company's treasury.  The Company
Preferred Shares are convertible into the number of Company Common Shares set
   17

                                     -13-

forth on Section 4.2 of the Company Disclosure Schedule. Section 4.2 of the
Company Disclosure Schedule also indicates how  many shares of each holder were
subject to repurchase upon termination of employment as of the date of execution
of this Agreement.  All outstanding Company Shares are duly authorized, validly
issued, fully paid and nonassessable and not subject to preemptive rights
created by statute, the Amended and Restated Articles of Incorporation or
by-laws of the Company or any agreement to which the Company is a party or is
bound.  The Company has reserved 4,306,500 Company Common Shares for issuance
pursuant to the Option Plans, of which 1,084,407 shares have been exercised,
2,749,132 shares are subject to outstanding, unexercised options and 472,961
shares remain available for future grant.  Section 4.2 of the Company Disclosure
Schedule sets forth for each outstanding option the name of the holder of such
option, the number of shares subject to such option, the exercise price of such
option, the numbers of shares as to which such option is exercisable and, if the
exercisability of such option will be accelerated in any way by the transactions
contemplated by this Agreement, an indication of the extent of such
acceleration.  Section 4.2 of the Company Disclosure Schedule also describes any
repricing of options which has taken place since January 1, 1991.  Except as set
forth in Section 4.2 of the Company Disclosure Schedule, there are no other
options, warrants, calls, rights, commitments or agreements of any character 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 the capital stock of the Company or
obligating the Company to grant, extend or enter into any such option, warrant,
call, right, commitment or agreement.

        Section 4.3  SUBSIDIARIES.  The Company has never had, nor does it
currently have, any subsidiaries.  Except as disclosed in Section 4.3 of the
Company Disclosure Schedule, the Company has never owned, nor does it currently
own, directly or indirectly, any capital stock or other equity securities of any
corporation or have direct or indirect equity or ownership interest in any
association, partnership, joint venture or other entity.

        Section 4.4  AUTHORITY RELATIVE TO THIS AGREEMENT.  The Company has the
requisite corporate power and authority to enter into this Agreement and to
carry out its obligations hereunder. The execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby have been
duly authorized by the Company's Board of Directors and, except for the approval
of its shareholders, no other corporate proceedings on the part of the Company
are necessary to authorize this Agreement and the transactions contemplated
hereby.  This Agreement has been duly and validly executed and delivered by the
Company and, assuming this Agreement constitutes a valid and binding obligation
of each of Parent, Merger Sub and the Company Shareholders, this Agreement
constitutes a valid and binding agreement of the
   18

                                     -14-


Company, enforceable against the Company in accordance with its terms, except as
the enforceability hereof may be subject to or limited by bankruptcy,
insolvency, reorganization, arrangement or similar laws affecting the
rights of creditors generally, judicial limitations upon the specific
performance of certain types of obligations and public policy.

        Section 4.5  NON-CONTRAVENTION.  Subject to the approval of this
Agreement by the shareholders of the Company and assuming the receipt of all
Required Consents and Other Consents (each as defined in Section 4.6 below),
neither the execution, delivery or performance of this Agreement by the Company,
nor the consummation of the Merger or any other transaction described herein,
does or will, after the giving of notice, or the lapse of time, or otherwise:

        (a)  conflict with, result in a breach of, or constitute a default
under, the Amended and Restated Articles of Incorporation or the by-laws of the
Company or any federal, foreign, state or local court or administrative order or
process, or any contract, agreement or commitment to which the Company is a
party, or under which the Company is obligated, or by which the Company or any
of the rights, properties or assets of the Company are subject or bound;

        (b)  result in the creation of any mortgage, pledge, lien, claim,
charge, encumbrance or assessment upon, or otherwise adversely affect, any of
the rights, properties or assets of the Company;

        (c)  terminate, amend or modify, or give any party the right to
terminate, amend, modify, abandon or refuse to perform or comply with, any
contract, agreement or commitment to which the Company is a party, or under
which the Company is obligated, or by which the Company or any of the rights,
properties or assets of the Company are subject or bound; or

        (d)  accelerate, postpone or modify, or give any party the right to
accelerate, postpone or modify, the time within which, or the terms and
conditions under which, any liabilities, duties or obligations are to be
satisfied or performed, or any rights or benefits are to be received, under any
contract, agreement or commitment to which the Company is a party, or under
which the Company may be obligated, or by which the Company or any of the
rights, properties or assets of the Company are subject or bound.

Section 4.6  REQUIRED AND OTHER CONSENTS.

        (a) Section 4.6(a) of the Company Disclosure Schedule sets forth each
agreement, contract or other instrument binding upon the Company or any Permit
(as defined in Section 4.15 below) requiring a consent as a result of the
execution, delivery and
   19

                                     -15-

performance of this Agreement and the consummation of the transactions
contemplated hereby and thereby (each such consent, a "Required Consent"),
except such consents as would not, individually or in the aggregate, result
in a Material Adverse Change if not received by the Closing Date.

        (b) Section 4.6(b) of the Company Disclosure Schedule sets forth every
other consent (each such consent, an "Other Consent") under such agreements,
contracts or other instruments or such Permits that are necessary with respect
to the execution, delivery and performance of this Agreement and the
consummation of the transactions contemplated hereby and thereby.

        Section 4.7  FINANCIAL STATEMENTS AND REPORTS.  The Company has
previously furnished Parent with a true and complete copy of (a) the audited
balance sheets of the Company as of September 30, 1993 and 1992, and the audited
statements of operations, changes in shareholders' equity and changes in
financial position of the Company for the two fiscal years ended September 30,
1993 and (b) the unaudited statements of operations, changes in shareholder's
equity and changes in financial position of the Company for the fiscal year
ended September 30, 1994 and the unaudited balance sheet of the Company as of
September 30, 1994, and unaudited statements of income, changes in shareholders'
equity and changes in financial position of the Company for the twelve-month
period then ended (collectively, the "Company Financial Statements"). Each of
the balance sheets included in the Company Financial Statements (including any
related notes) fairly presents the financial position of the Company as of its
date and the other statements included in the Company Financial Statements
(including any related notes) fairly present the results of operations,
shareholders' equity and changes in financial position, as the case may be, of
the Company for the periods therein set forth, in each case in accordance with
generally accepted accounting principles consistently applied during the periods
involved (except as otherwise stated therein (or in any related notes)).  The
business plan previously prepared by the Company and delivered to Parent (the
"Projection"), was prepared in good faith, based on assumptions the Company
deems reasonable, was prepared for planning purposes, and no assurances are
given that the Company will engage in the activities described therein or
achieve the results projected therein.

        Section 4.8  TITLE TO PROPERTIES AND ASSETS.  On September 30, 1994 (the
"Balance Sheet Date"), the Company had, and now has, good and marketable title
to all of the properties and assets, tangible or intangible, or owned or used by
it, whether or not reflected in the balance sheet dated the Balance Sheet Date
(the "Balance Sheet") or subsequently acquired by it, subject to no mortgages,
pledges, liens, liens for taxes and governmental charges not yet due,
encumbrances or other charges of any kind except for those mortgages, pledges,
liens, encumbrances or charges disclosed in Section 4.8 of the Company

   20

                                     -16-

Disclosure Schedule.  Except as aforesaid, the assets and properties owned by
the Company at the Effective Time shall be free and clear of mortgages, pledges,
liens, encumbrances or charges of any kind, except for mechanics', carriers',
workmens' and other similar liens, liens for taxes and governmental charges not
yet due, rights of way, building or use restrictions and other
limitations of any kind which are not substantial in amount and do not
materially detract from the value of or materially interfere with the use of any
of the assets or properties subject thereto.  There is no material asset used or
required by the Company in the conduct of its business as presently operated
which is not either owned by it or licensed or leased to it under one of the
licenses or leases listed in Section 4.8 of the Company Disclosure Schedule. 
All of the fixtures, machinery, equipment, tools and other personal property
owned, leased or licensed by the Company are, and at the Effective Time will be,
in normal operating condition and repair, normal ordinary wear and tear
excepted.

        Section 4.9  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since the Balance
Sheet Date, there has not been:

        (a)  any Material Adverse Change and the Company has no knowledge of any
fact or anticipated event unique to the Company which, individually or in the
aggregate, may reasonably be expected to give rise to any Material Adverse
Change;

        (b)  any change in any method of accounting or accounting practice of
the Company;

        (c)  any declaration, setting aside or payment of any dividend or other
distribution with respect to any shares of capital stock of the Company, or any

outstanding shares of capital stock or other securities of, or other equity or
ownership interests in, the Company;

        (d)  any change in the Amended and Restated Articles of Incorporation
and by-laws of the Company or any amendment of any term of any outstanding
security (including the acceleration of option vesting and other terms relating
to exercisability) of the Company;

        (e)  any incurrence, assumption or guarantee by the Company of any
indebtedness for borrowed money other than in the ordinary course of business
and in amounts and on terms consistent with past practices, and under existing
agreements;

        (f)  any creation or assumption by the Company of any lien on any asset,
other than liens that do not in the aggregate materially detract from the value
of such assets or
   21

materially impair the use thereof in the operation of the business of the
Company;

        (g)  any making of any loan, advance or capital contributions to, or
investment in, any person;

        (h)  any sale, lease, pledge, transfer or other disposition of any
capital asset for aggregate consideration in excess of $25,000;

        (i)  any transaction or commitment made, or any contract or agreement
entered into, by the Company relating to its assets or business (including the
acquisition or disposition of any assets) or any relinquishment by the Company
of any contract or other right, in either case, material to the Company, other
than transactions, commitments and relinquishments in the ordinary course of
business consistent with past practices and those contemplated by this
Agreement;

        (j)  any (A) grant of any severance or termination pay to any director
or officer of the Company, (B) grant of any severance or termination pay prior

extended prior to the date hereof (each of which employees and offerees is
identified in the Company Disclosure Schedule), (y) employees for which offers
of employment are not in effect but whose employment is in the ordinary course
of the Company's business, consistent with past practices and the Company's
planning budget, and (z) as permitted by Parent in writing, (D) change in
benefits payable under existing severance or termination pay policies or
employment, severance, management, consulting or other similar agreements, (E)

        (a) No person, firm, corporation or entity who is a party to any
material contract, agreement, commitment or plan to which the Company is a party
has a valid defense, on account of non-performance or malfeasance by the
Company, which would make any such contracts, agreements, commitments and plans
not valid and binding upon or enforceable against such parties in accordance
with their terms, except to the extent such enforceability may be subject to or
limited by bankruptcy, insolvency, reorganization, arrangement or similar laws
affecting the rights of creditors generally and usual equity principles or would

the Company is a party, and no event or action has occurred, is pending, or, to
the best knowledge of the Company, is threatened, which, after the giving of
notice, or the lapse of time, or otherwise, would constitute a breach or a
default by the Company or, to the best knowledge of the Company, any other
person, firm, corporation or entity, under any contract, agreement, arrangement,
commitment or plan to which the Company is a party, except for any breach,
violation or default, which would not have, either individually or in the

its Agents, (ii) were available to the Company on a nonconfidential basis prior

contractual, legal or fiduciary obligation).  The Company will not release or
disclose such information or documents to any persons other than its Agents in

sale of the Company's capital stock or a merger, consolidation, sale of all or a
substantial portion of the assets of the Company or any similar transaction.

Company Shareholders and Company Affiliates listed on Exhibit C hereto (the

Code for the performance of their duties in connection with such use.

        (b)  The Company shall cause all Company employees who have access to
any Source Code to observe and comply with all provisions of this Agreement
prohibiting the use or disclosure of the Source Code.

        (c)  The Company will not, and shall not permit any of its employees to,

   46
                                     -42-


reason to any unauthorized Company personnel or to any other individual, firm,

obligation under a contract in effect as of the date hereof and disclosed on
the Company Disclosure Schedule.

        (d)  The Company shall not, and shall not permit any of its employees to
(i) reproduce or copy any Source Code, except as expressly permitted herein or
(ii) remove any copyright or proprietary notice contained or included in the

agreements.

        (f)  The Company shall use its reasonable efforts to identify and
prevent any use or disclosure of the Source Code by any present or former
employee of the Company in any manner which is not expressly permitted by this
Agreement.  Without limitation of the foregoing, the Company shall promptly
advise Parent if the Company learns that any employee or former employee who has
had access to the Source Code has violated or may violate any confidential
information agreement signed by such employee and shall cooperate with Parent in
seeking injunctive or other equitable relief, in the name of the Company,
against such employee.

        (g)  The Company shall use its best efforts to maintain and protect its
Source Code and shall make "back-up" copies of such Source Code from time to
time in accordance with good business practices.  The Company shall promptly and
from time to time provide Parent with the opportunity to review and approve the

and with respect to all other employee benefit programs (including dental
benefits programs) Parent, in its sole discretion, shall, during such period,
offer programs substantially similar to those offered by the Company on the date
hereof or to those offered by Parent to its U.S.-based employees; provided,
however, that Parent may integrate such employee benefit programs into Parents'
employee benefit programs.

        Section 5.14  FORM S-4.  In the event that the Closing does not occur by
December 31, 1994 solely as a result of the failure to satisfy Section 6.3(j)
hereof, then as promptly as practicable after December 31, 1994, the Company and
Parent shall cooperate in the preparation, and the Parent shall file with the
SEC, shareholder solicitation and other materials relating to the approval of
the Merger, this Agreement and the transactions contemplated hereby which will
be included within a Form S-4 Registration Statement (or such other or successor
form as shall be appropriate) (the "Form S-4"), which complies in form with
applicable SEC requirements and shall use all reasonable efforts to cause the
Registration Statement, in substantially the form so filed, to become effective
as soon thereafter as practicable. When the Form S-4 or any post-effective
amendment thereto shall become effective, and at all times subsequent to such
effectiveness, up to and including the delivery of the Company's Shareholders'
Consents, such Form S-4 and shareholder solicitation materials and all
amendments or supplements thereto, with respect to all information set forth
therein furnished or to be furnished by any party with respect to itself or its
affiliates, (i) will comply in all material respects with the applicable
provisions of the Securities Act of 1933 and the rules and regulations
promulgated by the Commission thereunder and (ii) will not contain any untrue
statement of a material fact or omit to state a material fact required to be

untrue statement of a material fact or omission to state a material fact in the
Form S-4 and shareholder solicitation materials made in reliance upon, and in
conformity with, written information concerning any other party hereto furnished
by such other party specifically for use in the Form S- 4 and shareholder
solicitation materials.  Each party hereto shall advise the other party hereto
promptly of the happening of any event which makes untrue any statement of a
material fact contained in the Form S-4 or shareholder solicitation materials or
any amendment or supplement thereto in order to make any material misstatement
therein not misleading.

        Section 5.15  INFORMATION DISCLOSURE.  At any time prior to the
Effective Time and any termination of this Agreement, Parent shall notify the

to herein, together with any other information delivered by the Company to
Parent or its independent public accountants on or before the date hereof, as
the "Information").  Such letter shall also contain a description of the
analysis to be applied to the Information by such accountants and shall identify
a conclusion regarding Code Section 382 that such accountants are requested to
confirm based upon their analysis of the Information (such conclusion is
referred to herein as the "IRC Conclusion"). The Company agrees to use its best
efforts to obtain the Information and to take, or cause to be taken, all things
necessary, proper or advisable to assist such accountants in their analysis of
the Information.  After a review of the Information by such accountants on the
terms described in the Letter, on or before December 31, 1994 Parent shall
inform the Company (or the Indemnification Representative if the Closing has
occurred prior to such date) in writing whether the IRC Conclusion has been
confirmed by such accountants.  Any determination by such accountants as to the
IRC Conclusion shall be final and not subject to appeal and shall not be subject
to arbitration under the terms of Section 7.8.  In the case that such
accountants do not confirm, after receipt of all requested Information, the IRC
Conclusion by December 31, 1994, Parent shall promptly deliver to the
Indemnification Escrow Agent a notice instructing the Indemnification Escrow
Agent to release the Special Escrow Shares (if any) to the Company Shareholders

Parent and the Indemnification Representative (on behalf of the Company
Shareholders) agree that
   49
                                     -45-


the Special Escrow Shares shall be returned to Parent under the terms of Article
VII (or if the Closing has not yet occurred, withheld from the merger
consideration pursuant to the adjustments set forth in the second paragraph of
Section 2.1(c)) and Parent shall promptly notify the Company, the
Indemnification Escrow Agent and the Indemnification Representative of such
fact. Notwithstanding the foregoing, in the case that the Closing occurs prior
to December 31, 1994, the Company shall make binding arrangements with a third
party or parties to assume the obligations of the Company under this Section
5.17, and the Company and the Indemnification Representative (on behalf of the
Company Shareholders) covenant and agree that Parent shall be in no way
obligated as a successor or by operation of law to perform any of such
obligations of the Company described in this Section 5.17.

        organized, validly existing and in good standing under the laws of the
        State of Delaware and the State of California, respectively, with
        corporate power to own its property and to conduct its business as now

        and Merger Sub, as applicable, to execute and deliver this Agreement,
        the Agreement of Merger and the Registration Rights Agreement (as
        defined below), and to perform their obligations hereunder and
        thereunder;

                (iii)  The execution and delivery of this Agreement, the
        Agreement of Merger and the Registration Rights Agreement by Parent and
        Merger Sub, and the performance of their obligations hereunder and
        thereunder will not result in the violation of any order or decree known
        to such counsel of any court binding upon Parent or Merger Sub or their
        property;

   51
                                     -47-


                (iv)  Each of this Agreement, the Agreement of Merger and the
        Registration Rights Agreement has been duly authorized, executed and
        delivered by Parent and Merger Sub, as applicable, and is binding upon
        and enforceable against Parent and Merger Sub, as applicable, in
        accordance with its terms, except as the enforceability hereof or
        thereof may be subject to or limited by bankruptcy, insolvency,
        reorganization, arrangement or similar laws affecting the rights of
        creditors generally, judicial limitations upon the specific performance
        of certain types of obligations and public policy;

                (v)  All authorizations, consents and approvals of all

        the Registration Rights Agreement have been obtained (it being
        understood that such counsel need not express an opinion with respect to
        antitrust and trade regulation laws or state "blue sky" laws);

                (vi)  The Shares of Parent Common Stock deliverable pursuant to
        this Agreement and the Agreement of Merger at the Closing are, and the
        Shares of Parent Common Stock issuable upon exercise of the Options
        after assumption thereof by Parent will upon issuance be, duly
        authorized, validly issued, fully paid and nonassessable, and are and
        will be, as the case may be, not subject to any preemptive rights or
        rights of first refusal either arising pursuant to any agreement or

Company Shareholders and holders of those Outstanding Company Options not issued

        effect and are all the resolutions adopted in connection with the
        transactions contemplated by this Agreement and the Agreement of Merger;
        (C) that the certificate of incorporation and articles of incorporation
        of Parent and Merger Sub, as the case may be, have not been amended

subsequent Closing shall not in any way limit Parent's or the Surviving
Corporation's right to indemnification pursuant to Article VII; and at the
Closing Parent and Merger Sub shall have received a certificate executed by the
President of the Company to the foregoing effects;

        (b)  No investigation, action, suit or proceeding by any governmental or
regulatory commission, agency, body or authority, and no action, suit or
proceeding by any other person, firm, corporation or entity, shall be pending on
the Closing Date which challenges, or might reasonably be expected to result in
a challenge to, this Agreement or the Merger or any other transaction
contemplated hereby, or which claims, or might reasonably be expected to give
rise to a claim for, damages in a material amount as a result of the
consummation of the Merger or any other transaction contemplated hereby;

                                     -50-


        (c)  At the Closing, there shall be delivered to Parent and Merger Sub
the opinion of Fenwick & West, counsel for the Company, dated the Closing Date,
in form and substance satisfactory to Parent and Merger Sub and their counsel,
to the effect that:

                (i)  The Company is a corporation duly organized, validly
        existing and in good standing under the laws of the state of its
        incorporation with corporate power to own its property and to conduct
        its business as now conducted and is duly licensed or qualified to do
        business and is in good standing as a foreign corporation in all
        jurisdictions in which character of the assets owned or leased by it
        makes such license or qualification necessary;

                (ii)  The authorized, issued and outstanding capital stock of
        the Company on the Closing Date is as set forth in such opinion. 
        Immediately prior to the Closing, except as set forth in the Company
        Disclosure Schedule, to the knowledge of such counsel, no subscription,
        warrant, option, convertible security, or other right (contingent or
        other) to purchase or acquire equity securities of the Company will be
        authorized or outstanding and there will be no commitment by the Company
        to issue shares, subscriptions, warrants, options, convertible
        securities, or other such rights or to distribute to holders of any of
        its equity securities any evidence of indebtedness or asset.  Except as
        set forth in the Company Disclosure Schedule or as provided for in the
        Amended and Restated Articles of Incorporation of the Company, to the
        knowledge of such counsel the Company has no obligation (contingent or
        other) to purchase, redeem or otherwise acquire any of its equity
        securities or any interest therein or to pay any dividend or make any
        other distribution in respect thereof

                (iii)  The issued and outstanding shares of capital stock of the
        Company have been duly and validly issued and are fully paid and
        nonassessable;  all of the outstanding shares of capital stock of the
        Company did not require registration under the Securities Act (assuming
        the accuracy of representations made by purchasers of such stock) except
        as set forth on the Company Disclosure Schedule;

                (iv)  There is no litigation, action, suit, investigation, or
        proceeding pending, or threatened, against or affecting the Company
        which, individually or in the aggregate, might result in any Material
        Adverse Change (as defined in Article IV) except as set forth in the
        Company Disclosure Schedule;

                (v)  All requisite corporate action has been taken by the
        Company under its Amended and Restated Articles of Incorporation and
        by-laws and the laws of the State of
   55
                                     -51-


        California to enable the Company to execute and deliver this    
        Agreement and the Agreement of Merger and to perform its obligations
        hereunder and thereunder;

                (vi)  The execution of this Agreement and the Agreement of
        Merger by the Company, and the performance of its obligations hereunder
        and thereunder, will not result in the violation of any order or decree
        known to such counsel of any court binding upon the Company or its
        property, or conflict with or constitute a default under, the Company's
        articles of incorporation or by-laws or under any note, debt instrument,
        security agreement or mortgage, or any other material agreement or
        commitment; identified by the Company by which the Company is bound, or
        result in the creation or imposition of any lien or encumbrance in favor
        of any third person upon any of the property of the Company;

                (vii)  This Agreement and the Agreement of Merger have been duly
        authorized, executed and delivered by the Company, as applicable, and
        are binding upon and enforceable against the Company in accordance with
        their respective terms, except as the enforceability hereof or thereof
        may be subject to or limited by bankruptcy, insolvency, reorganization,
        arrangement or similar laws affecting the rights of creditors generally,
        judicial limitations upon the specific performance of certain types of
        obligations and public policy;

                (viii)  All authorizations, consents and approvals of all
        governmental agencies and authorities of the United States, the State of
        California and the State of Delaware required in order to permit
        consummation by the Company of the transactions contemplated by this
        Agreement and Agreement of Merger have been obtained (it being
        understood that such counsel need not express an opinion with respect to
        antitrust and trade regulation laws or respecting the availability of an
        exemption from the registration requirements of the Securities Act or
        applicable state securities laws); and

                (ix)  Upon the filing of the Agreement of Merger and Officers'
        Certificates at the Effective Time, the Merger shall be effective under
        the laws of the State of California.

In rendering such opinion, Fenwick & West may rely as to matters governed by the
laws of the states other than the State of California or the State of
Delaware on local counsel in such jurisdictions.

        (d)  Parent shall have received an unqualified written opinion from
Ernst & Young, Parent's independent accountants, that Parent should account for
the Merger as a "pooling of interests" under applicable rules and regulations of
the Commission.

   56
                                     -52-


        (e)  Employment agreements in forms previously approved by Parent and
the Company shall have been entered into with each of Kenneth Ross, Beverly
Powell, Lee Harris and Kimberly Weins (the "Employment Agreements");

        (f)  The Company shall have received all Required Consents and all
consents, authorizations or approvals from the governmental agencies, as well as
all consents and waivers required under the Company's articles of incorporation,
(including as pertains to the Merger not constituting a liquidation event under
such articles of incorporation and those set forth in section 4.4 of the Company
Disclosure Schedule) in each case in form and substance satisfactory to Parent
and Merger Sub and their counsel, and no such consent, authorization or approval
shall have been withdrawn.

        (g)  Holders of Company Shares representing at least ninety-five percent
(95%) of the voting power of Company Shares entitled to approve the Merger and
this Agreement shall have executed and delivered the Company's Shareholders'
Consent in favor of the transactions contemplated herein and the Participation
Agreements shall have been entered into by each of the parties identified in
Section 5.7.

        (h)  All corporate and other proceedings to be taken by the Company in
connection with the transactions contemplated hereby and all documents incident
thereto shall be satisfactory in form and substance to Parent and Merger Sub and
their counsel, and Parent and Merger Sub and their counsel shall have received
all such counterpart originals or certified or other copies of such documents as
they reasonably may request.

        (i)  At or prior to the Closing, Parent and Merger Sub and their counsel
shall have received copies of the following documents:

                (i)   (A) the articles of incorporation of the Company,
        certified as of a recent date by the Secretary of State of the State of

        a certificate of the Franchise Tax Board as to the payment of all
        franchise taxes by the Company;

                (ii)  a certificate of the Secretary or an Assistant Secretary
        of the Company dated the Closing Date and certifying:  (A) that attached
        thereto is a true and complete copy of the By-laws of the Company as in
        effect on the date of such certification; (B) that attached thereto is a
        true and complete copy of all resolutions adopted by the Board of

                                     -53-


        Agreement of Merger, and that all such resolutions are in full force and
        effect and are all the resolutions adopted in connection with the       
        transactions contemplated by this Agreement and the Agreement of 
        Merger; (C) that the articles of incorporation of the Company have not
        been amended since the date of the last amendment referred to in the
        certificate delivered pursuant to clause (i)(B) above; and (D) as to 
        the incumbency and specimen signature of each officer of the Company

        officer of the Company as to the incumbency and signature of the officer
        signing the certificate referred to in this clause (ii); and

                (iii)  such additional supporting documents and other
        information with respect to the operations and affairs of the Company as
        Parent and Merger Sub or their counsel reasonably may request.

        (j)  Parent shall be satisfied, in its sole discretion, that the
approval of the Merger, this Agreement and all associated transactions by the
Company Shareholders and the issuance of Parent Common Stock hereunder shall
have been conducted in compliance with Regulation D of the Securities Act of
1933, as amended.

        (k)  The Company shall have furnished Parent with a true and complete

the audited statements of operations, changes in shareholders' equity and
changes in financial position of the Company for the fiscal year ended September

                                  ARTICLE VII

             SURVIVAL OF REPRESENTATIONS, WARRANTIES and COVENANTS;
                                INDEMNIFICATION

        Section 7.1  SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.  All
representations, warranties and covenants of the Company, Parent and Merger Sub
contained herein or in any schedule, document, written statement, certificate or
other instrument delivered by or on behalf of the Company in connection with the
transactions contemplated hereby shall survive the execution and delivery of
this Agreement, any investigation by or on behalf of the Company, Parent or
Merger Sub, as the case may be, and the completion of the transactions
contemplated hereby and shall terminate upon the publication of Parent's audited
financial results for the year ended June 30, 1995; provided, however, that the
sole method of enforcing liability against the Company Shareholders, or any of
them, under this Agreement, and any recovery of losses against such persons
shall be subject to the terms of this Article VII.

        Section 7.2  INDEMNIFICATION.

        (a)  Parent and the Surviving Corporation shall be indemnified and held
harmless until the publication of Parent's audited financial results for the
year ended June 30, 1995 (the "Escrow Termination Date") from and against any
loss, expense, liability or other damage (including reasonable legal and
accounting fees and costs) suffered by Parent or the Surviving Corporation
resulting from:

        (i)  any breach by the Company of this Agreement; or

        (ii)  any inaccuracy in or breach of any of the representations,
warranties, or covenants made by the Company in this Agreement as modified and
supplemented by the Company Disclosure Schedule; or

        (iii)  any inaccuracy or misrepresentation in a document, certificate or
affidavit delivered by the Company or in accordance with the provisions of this
Agreement.

        (b)  Parent's and the Surviving Corporation's right to make claims
against the Indemnification Escrow Shares hereunder shall provide the sole
method of enforcing the right to indemnification pursuant to Section 7.2(a);
provided, however, that nothing in this Agreement shall be deemed to limit any
right or remedy of Parent or the Surviving Corporation for criminal activity or
fraud, or breaches of covenants or inaccuracies in any representations or
warranties set forth in the Participation Agreement.

   59
                                     -55-


        (c)  Parent and the Surviving Corporation shall not be entitled to
indemnification hereunder (out of the Indemnification Escrow Shares) until the
aggregate amount of all losses, expenses, liabilities and other damages suffered
by Parent or the Surviving Corporation exceeds $100,000 (including attorney's
fees and expenses incurred in connection therewith) (the "Threshold") whereupon
Parent and the Surviving Corporation shall be entitled to indemnification
hereunder (out of the Indemnification Escrow Shares) for the aggregate amount of
all of such losses, expenses, liabilities and other damages suffered by Parent
or the Surviving Corporation, without taking into account the Threshold but in
no event exceeding the Indemnification Escrow Shares (except as set forth in
Section 7.2(b)).

        Section 7.3  DISTRIBUTIONS AND CLAIMS.

        (a)  Upon obtaining knowledge of any state of facts, claim or demand
which has given rise to, or could reasonably give rise to, a claim for
indemnification hereunder (referred to herein as an "Indemnification Claim"),
Parent shall give written notice of such state of facts, claim or demand
("Notice of Claim") to the Indemnification Representative and to the
Indemnification Escrow Agent.  A Notice of Claim shall be given whether or not
the Threshold has been reached.  Parent shall not be entitled to give a Notice
of Claim after the Escrow Termination Date except with respect to any matter
which was the subject of a Notice of Claim given prior to such date.  The Notice
of Claim shall set forth the amount of the loss, expense, liability or other
damage suffered, or which may be suffered, by Parent or the Surviving
Corporation.  Parent shall furnish to the Indemnification Representative in
reasonable detail such information, correspondence and documentation as Parent
may have with respect to such Indemnification Claim.  So long as the Notice of
Claim is given by Parent prior to the Escrow Termination Date, no failure or
delay by Parent in the performance of the foregoing shall reduce or otherwise
affect Parent's or the Surviving Corporation's right to indemnification
hereunder except to the extent that the Company Shareholders (as beneficial
owners of the Indemnification Escrow Shares) have been prejudiced thereby.  The
date that a Notice of Claim shall be deemed to be made hereunder shall be:

         (x) the second business day after the date of the postmark on the
             registered or certified mail containing the Notice of Claim; or

         (y) if the Notice of Claim is personally delivered, the date of
             such personal delivery.

        (b)(i)  Upon receipt by the Indemnification Escrow Agent at any time
prior to the Escrow Termination Date of a Notice of Claim, the Indemnification
Escrow Agent shall, subject to the provisions of Section 7.3(b)(ii) hereof,
deliver to Parent
   60
                                     -56-


out of the Escrow Fund, as promptly as practicable after expiration of the
twenty-day notice period related to a Challenged Claim, Indemnification Escrow
Shares having a market value equal to the amount set forth in the Notice of
Claim.  The market value of an Indemnification Escrow Share, for the purpose    
of this Section 7.3, shall be equal to (i) the Transaction Value divided by
607,297 if the Average Price is greater than $34.00 per share and (ii) the
Average Price in all other cases.

        (ii)  The Indemnification Representative shall have twenty (20) days
from the date of a Notice of Claim within which to object, by written notice of
objection given to Parent and the Indemnification Escrow Agent, to any
Indemnification Claim (a "Challenged Claim").  If notice of objection to any
such claim is not provided by the Indemnification Representative, the validity
and stated amount of the claim will be deemed to have been accepted (such claims
being referred to herein as "Accepted Claims").  The parties shall submit the
matter of a Challenged Claim to arbitration in accordance with Section 7.8
hereof.  If a Notice of Claim sets forth a claim or demand asserted by a third
party (a "Third Party Claim"), the Indemnification Representative shall have the
right, at the expense of the Company Shareholders as set forth herein, to
participate in but not assume control of the defense of such claim (which
defense shall be controlled by Parent).  If the Indemnification Representative
does not elect to participate in the defense of such third-party claim, the
Company Shareholders shall nevertheless be bound by the results of such claim or
litigation.  In the event that the Indemnification Representative shall
undertake to participate in any such matter, he shall promptly notify Parent and
the Company Shareholders of his intention to do so, and Parent agrees to
cooperate with the Indemnification Representative in the compromise of, or
defense against, any such matter (at the expense of the Company Shareholders);
PROVIDED, HOWEVER, that neither Parent, the Indemnification Representative nor
the Company Shareholders shall agree to a settlement of any such matter without
the prior written consent of both Parent and the Indemnification Representative,
which consent will not be unreasonably withheld.

        (iii)  The Indemnification Escrow Agent shall retain in escrow after the
Escrow Termination Date the number of Indemnification Escrow Shares (computed to
the nearest whole share) having a market value equal to the sum of (i) the
dollar amount of all Challenged Claims and pending or threatened Indemnification
Claims of this Section which have not been finally determined and (ii) the
anticipated expenses of the Indemnification Representative, as estimated by the
Indemnification Representative.  The "dollar amount" of any Indemnification
Claim shall be calculated assuming the maximum possible exposure, EXCEPT,
however, that, with respect to an Indemnification Claim for which legal action
has not been taken against Parent or the Surviving Corporation within two years
following the Notice of Claim (the "Period"), then the dollar

   61
                                     -57-


amount of such Indemnification Claim shall be as agreed upon by Parent and the
Indemnification Representative, and if they cannot agree within 90 days of the
end of the Period, then such dollar amount shall be determined by       
arbitration in accordance with Section 7.8 herein.

        (iv)  On the Escrow Termination Date, the Indemnification Escrow Agent
shall deliver to the Company Shareholders the balance of the Indemnification
Escrow Shares not delivered to Parent or the Surviving Corporation, as
applicable, or retained in escrow pursuant to Section 7.3(b)(iii) or delivered
to the Indemnification Representative as reimbursement for expenses.  Each
Company Shareholder shall receive his proportional share interest in such
distribution, to be determined as follows:  the number of Indemnification Escrow
Shares to be distributed to each Company Shareholder shall be multiplied by a
fraction, the numerator of which is the number of shares of Parent Common Stock
(including fractional shares) delivered to the Indemnification Escrow Agent for
such Company Shareholder's account at the Effective Time of the Merger, and the
denominator of which is the aggregate number of Indemnification Escrow Shares
delivered to the Indemnification Escrow Agent at the Effective Time of the
Merger.  If any Indemnification Escrow Shares are retained to provide for
pending Indemnification Claims and expenses, then each Company Shareholder's
distributed interest shall be rounded down to the next number of whole shares,
and fractional shares shall be retained in escrow.  If no Indemnification Escrow
Shares are retained, then the distribution to each Company Shareholder shall
include each cash payment by Parent in lieu of fractional shares as provided in
subparagraph (c) of this Section 7.3.

        (c)  Indemnification Escrow Shares that are not distributed to the
Company Shareholders on the Escrow Termination Date because they have been
retained pursuant to Section 7.3(b)(iii) shall be distributed (as appropriate)
as promptly as practicable after disposition of each such Indemnification
Claim.  Upon the date after which the last of all Challenged Claims and all
other Indemnification Claims has been finally determined and the final
distribution has been made to Parent (and to the Indemnification
Representative, if applicable) (the "Termination Date"), the balance of all
Indemnification Escrow Shares shall be delivered to the Company Shareholders,
subject to cash payment by Parent in lieu of fractional shares as hereinafter
provided, and the escrow shall be terminated.  In lieu of such fractional
shares, any Company Shareholder who would otherwise be entitled to a fraction
of an Indemnification Escrow Share (after aggregating all fractional
Indemnification Escrow Shares to be received by such holder) will be paid the
cash value of such fraction, which shall be equal to the fraction multiplied by
an amount equal to (i) the Transaction Value divided by 607,297 if the Average
Price is greater than $34.00 per share and (ii) the Average Price in all other
cases.  Parent shall make a

   62

                                     -58-

cash payment to the Indemnification Representative in an amount equal to the
aggregate of all cash distributions to Company  Shareholders.

        (d)  In the event that Parent shall deliver the Special Notice to the
Indemnification Escrow Agent pursuant to the terms of Section 5.17, the
Indemnification Escrow Agent shall promptly deliver the Special Escrow Shares
(if any) to the Company Shareholders.  In the event of such distribution of the
Special Escrow Shares to the Company Shareholders, each Company Shareholder
shall receive its proportional share interest of such distribution (determined
in the same manner as in subsection (b) above), subject to cash payment by
Parent in lieu of fractional shares as follows:  any Company Shareholder who
would otherwise be entitled to a fraction of a Special Escrow Share (after
aggregating all fractional Special Escrow Shares to be received by such holder)
will be paid the cash value of such fraction, which shall be equal to the
fraction multiplied by an amount equal to (i) the Transaction Value divided by
607,297, if the Average Price is greater than $34.00 per share and (ii) the
Average Price in all other cases.  Parent shall make a cash payment to the
Indemnification Representative in an amount equal to the aggregate of all cash
distributions to Company Shareholders.

        If the Special Notice is not delivered to the Indemnification Escrow
Agent pursuant to the terms of Section 5.17, the Indemnification Escrow Agent
shall promptly deliver all of the Special Escrow Shares (if any) to Parent.

        Section 7.4  VOTING RIGHTS AND DISTRIBUTIONS.

        (a)  The Indemnification Escrow Shares and the Special Escrow Shares (if
any), unless and until delivered to Parent pursuant to this Agreement, or
distributed to the Indemnification Representative or to the Company
Shareholders, shall be registered in the respective names of the Company
Shareholders, who shall be entitled to vote their respective Indemnification
Escrow Shares and the Special Escrow Shares (if any).  All cash dividends or
distributions of assets declared by Parent with respect to its Common Stock
prior to the Termination Date, shall be payable to the Company Shareholders as
if each had received all of the shares of Parent Common Stock deliverable to him
at the Effective Time of the Merger and no shares had been placed into escrow
under this Agreement (subject to reduction to reflect the delivery of
Indemnification Escrow Shares and/or Special Escrow Shares (if any) to Parent,
the Surviving Corporation or the Indemnification Representative (as
reimbursement of expenses) under this Agreement).

        (b)  All shares of Parent Common Stock relating to Indemnification
Escrow Shares and the Special Escrow Shares (if any) still held by the
Indemnification Escrow Agent under this
   63
                                     -59-


Agreement and resulting from conversion, stock dividend, stock split,
reclassification, recapitalization or corporate reorganization of Parent, shall
be delivered to the Indemnification Escrow Agent when deliverable to holders of
other outstanding shares of Parent Common Stock, shall be credited to the
accounts of the Company Shareholders and shall constitute additional
Indemnification Escrow Shares or Special Escrow Shares (if any), as the case may
be.

        Section 7.5  THE INDEMNIFICATION REPRESENTATIVE.

        (a)  As long as there are shares held in escrow pursuant to this
Agreement, the Company Shareholders, and each of them, will be represented by
the Indemnification Representative to receive any notice under this Agreement
for the Company Shareholders, and each of them, and to give any and all notices
and instructions and take any and all action for and on behalf of the Company
Shareholders, and each of them, under this Agreement. The Company Shareholders
will have the right to remove the Indemnification Representative and, upon such
removal or, in the event of the Indemnification Representative's death or
resignation, to appoint as the new Indemnification Representative any Company
Shareholder at any time and from time to time during the period when any shares
are held in escrow, by a vote of Company Shareholders holding a majority
interest in the Indemnification Escrow Shares held in escrow at such time
evidenced by a writing executed by such majority Company Shareholders.  The
appointment of a new Indemnification Representative will be of no force or
effect whatsoever upon Parent or the Indemnification Escrow Agent or otherwise
under this Agreement until three days after the later of the dates when Parent
or the Indemnification Escrow Agent receives written notice of such appointment,
which notice must include at least: (i) the identity and address of the new
Indemnification Representative and a statement that such Indemnification
Representative has been appointed by a vote of Company Shareholders holding a
majority interest in the Indemnification Escrow Shares then held in escrow; (ii)
the duly acknowledged signatures of each of the Company Shareholders voting for
the new Indemnification Representative; and (iii) a statement that any
non-signing Company Shareholder has been notified in writing of the appointment
of the new Indemnification Representative. Parent and the Indemnification Escrow
Agent will be entitled to rely on any notice received in such form without
conducting an investigation of the contents thereof.  Any notice given to the
Indemnification Representative will constitute notice to each and all of the
Company Shareholders at the time notice is given to the Indemnification
Representative.  Any action taken by, or notice or instruction received from,
the Indemnification Representative will be deemed to be action by, or notice or
instruction from, each and all of the Company Shareholders. Parent may and the
Indemnification Escrow Agent will disregard any notice or instruction received
from any Company Shareholder other than the then acting Indemnification
Representative with regard to this Agreement.

   64
                                     -60-


        (b)  The Indemnification Representative shall not suffer any liability
or loss for any act performed or omitted to be performed by him under this
Agreement in the absence of gross negligence or willful misconduct.  The
Indemnification Representative may consult with counsel in connection with his
duties hereunder and shall be fully protected by any act taken, suffered,
permitted, or omitted in good faith in accordance with the advice of counsel. 
The Indemnification Representative shall not be responsible for the sufficiency
or accuracy of the form, execution, validity or genuineness of documents or
securities now or hereafter deposited hereunder, or of any endorsement thereof
or for any lack of endorsement thereon, or for any description therein, nor
shall he be responsible or liable in any respect on account of the identity,
authority or rights of the persons executing or delivering or purporting to
execute or deliver any such document, security or endorsement, and the
Indemnification Representative shall be fully protected in relying upon any
written notice, demand, certificate or document which he in good faith believes
to be genuine.

        (c)  The Indemnification Representative shall be entitled to employ such
legal counsel and other experts as he may deem necessary to advise him properly
with respect to his rights and obligations hereunder and to evaluate
Indemnification Claims and to pursue challenges to Indemnification Claims or to
defend Third Party Claims.  The reasonable expenses and fees of such counsel and
experts, and any reasonable, documented out of pocket expenses which the
Indemnification Representative incurs under Section 7.3 or hereunder in relation
to evaluating, challenging or contesting claims, shall be reimbursed by Parent.
Reimbursement of such expenses of the Indemnification Representative shall occur
within thirty (30) days of delivery of an invoice to Parent and the
Indemnification Escrow Agent; provided, however, that the Indemnification
Representative shall not be entitled to reimbursement for expenses incurred in
excess of $25,000 in the aggregate without the prior written consent of Parent,
which consent will not be unreasonably withheld.

        (d)  The Indemnification Representative hereby agrees to do such other
acts, and execute such further documents, as the Indemnification Escrow Agent or
Parent shall deem necessary to carry out the provisions of this Agreement or to
transfer any Indemnification Escrow Shares and Special Escrow Shares (if any)
pursuant to the terms hereof.

        Section 7.6  INTEREST IN ESCROW SHARES.  The interest of the Company
Shareholders in the Indemnification Escrow Shares and the Special Escrow Shares

        Section 7.7  PROVISIONS CONCERNING THE ESCROW AGENT.

        (a)  The Indemnification Escrow Agent shall be entitled to reasonable
compensation for all services rendered and expenses incurred by it in the
performance of its obligations hereunder. The Indemnification Escrow Agent shall
be entitled to employ such legal counsel and other experts as it may deem
necessary to properly advise it in connection with its obligations hereunder,
and may rely on the advice of such counsel, and may pay them reasonable
compensation therefor.  The Indemnification Escrow Agent and such legal
counsel's and other expert's fees and expenses shall be borne by Parent;
PROVIDED, however, that if the aggregate amount of all Indemnification Claims
exceeds the Threshold, then such fees and expenses shall be shared one-half by
Parent and one-half by the Company Shareholders out of the Indemnification
Escrow Shares.

        (b)  The Indemnification Escrow Agent shall not be liable for any
diminution of value of the Indemnification Escrow Shares or Special Escrow
Shares (if any).  The Indemnification Escrow Agent shall have no authority to
sell or otherwise dispose of or encumber the Indemnification Escrow Shares and
the Special Escrow Shares (if any) except as provided herein.

        (c)  Notwithstanding any other provisions herein contained, the
Indemnification Escrow Agent may at all times act upon and in accordance with
the joint written instructions of Parent and the Indemnification
Representative.  The Indemnification Escrow Agent shall not be liable for any
act done or omitted by it in accordance with such instructions or pursuant to
the advice of counsel of its selection.

        (d)  The duties and responsibilities of the Indemnification Escrow Agent
shall be limited to those expressly set forth in this Agreement and instructions
given to the Indemnification Escrow Agent pursuant to this Agreement, and the
Indemnification Escrow Agent shall not be subject to, nor obligated to
recognize, any other agreement between any or all of the parties hereto even
though reference thereto may be made herein; PROVIDED, HOWEVER, with the written
consent of the Indemnification Escrow Agent, this Agreement may be amended at
any time by an instrument in writing signed by Parent and the Indemnification
Representative.  The Indemnification Escrow Agent shall advise Parent from time
to time, upon request, as to (i) the number of Indemnification Escrow Shares or
Special Escrow Shares (if any) represented by certificates surrendered to the
Indemnification Escrow Agent, and (ii) the number of Indemnification Escrow

        (e)  The Indemnification Escrow Agent shall not be responsible for the
sufficiency or accuracy of the form, execution, validity or genuineness of
documents or securities now or hereafter deposited hereunder, or of any
endorsement thereof, or for any lack of endorsement thereon, or for any
description therein, nor shall it be responsible or liable in any respect on
account of the identity, authority or rights of the persons executing or
delivering or purporting to execute or deliver any such document, security or
endorsement of this Agreement, and the Indemnification Escrow Agent shall be
fully protected in relying upon any written notice, demand, certificate or
document which it in good faith believes to be genuine.

        (f)  The Indemnification Escrow Agent is authorized, in its sole
discretion, to disregard any and all notices or instructions given by any of the
undersigned or by any other person, firm or corporation, except only such
notices or instructions as are herein provided for and orders or process of any
court entered or issued with or without jurisdiction.  If any property subject
hereto is at any time attached, garnished or levied upon under any court order,
or in case the payment, assignment, transfer, conveyance or delivery of any such
property shall be stayed or enjoined by any court order, or in case any order,
judgment or decree shall be made or entered by any court affecting such property
or any part thereof, then and in any of such events, the Indemnification Escrow
Agent is authorized, in its sole discretion, to rely upon and comply with any
such order, writ, judgment or decree which the Indemnification Escrow Agent is
advised by legal counsel of its own choosing is binding upon it; and if the
Indemnification Escrow Agent complies with any such order, writ, judgment or
decree, it shall not be liable to any of the parties hereto or to any other
person, firm or corporation by reason of such compliance even though such order
writ, judgment or decree may be subsequently reversed, modified, annulled, set
aside or vacated.

        (g)  The Indemnification Escrow Agent may resign by giving sixty (60)
days' advance written notice to Parent and the Indemnification Representative
and thereafter shall deliver the Indemnification Escrow Shares (and the Special
Escrow Shares (if any) if not yet delivered from escrow) to such substitute
escrow agent as Parent and the Indemnification Representative shall jointly
direct in writing.  If such discretion to deliver to a substitute escrow agent
is not received by the Indemnification Escrow Agent within sixty (60) days after
mailing such notice of resignation, it is unconditionally and irrevocably
authorized, directed and empowered to deliver all items held by it to any other
bank or trust company in the City of New York with capital and surplus of at
least $20,000,000 which is selected by the Indemnification Escrow Agent; such
bank or trust company then shall hold the same as the Indemnification Escrow
Agent, subject to the provisions hereof.

   67
                                     -63-


        (h)  In consideration of its acceptance of the appointment as the
Indemnification Escrow Agent, the Parent agrees to indemnify and hold the
Indemnification Escrow Agent harmless as to any liability incurred by it to any
person, firm or corporation by reason of its having accepted the same or in
carrying out any of the terms hereof (except as such liability may arrive out of
or be bared upon the gross negligence or willful misconduct of the
Indemnification Escrow Agent), and to reimburse the Escrow Agent for all its
reasonable expenses, including, among other things, counsel fees and court
costs, incurred by reason of its position hereunder or actions taken pursuant
hereto.

        Section 7.8  ARBITRATION.  All disputes related to the indemnification
obligations of the Company Shareholders under the provisions of this Article VII
shall be submitted to, and settled by, arbitration in New York, New York, in
accordance with the Rules of the American Arbitration Association.  The dispute
shall be submitted to one arbitrator agreed to by Parent or the Surviving
Corporation and the Indemnification Representative.  If Parent or the Surviving
Corporation and the Indemnification Representative cannot agree on one
arbitrator, one arbitrator will be selected by each party, with the two selected
arbitrators then selecting a third arbitrator.  The fees of the arbitration or
arbitrators shall be shared one-half by Parent or the Surviving Corporation and
one-half by the Company Shareholders. Any arbitration award may be entered in
and enforced by any court having jurisdiction thereover and the parties hereby
consent and commit themselves to the jurisdiction of the courts of the State of
California for the purposes of the enforcement of any arbitration award.

              owned by you or otherwise issuable to you by Pillar in
              connection with the transactions contemplated by the Acquisition
              Agreement.

        4.  SECURITIES ACT MATTERS.  You acknowledge and agree that the Common
Shares to be issued to you have not been (and at the time of acquisition by you,
will not have been) registered under the Securities Act or under the securities
laws of any state, in reliance upon certain exemptive provisions of such
statutes.  You recognize and acknowledge that such claims of exemption are
based, in part, upon your representations contained in this Agreement.  You
further recognize and acknowledge that, because the Common Shares are
unregistered under federal and state laws, they are not presently eligible for
resale, and may only be resold in the future pursuant to an effective
registration statement under the Securities Act and any applicable state
securities laws, or pursuant to a valid exemption from such registration
requirements.  You recognize and acknowledge that Rule 144 promulgated under the
Securities Act (which facilitates
   76
                                      -3-


routine sales of securities in accordance with the terms and conditions of that
Rule, including a holding period requirement) is not now be available to you for
resale of the Common Shares,    and you recognize and acknowledge that, in the
absence of the availability of Rule 144, a sale pursuant to a claim of exemption
from registration under the Securities Act would require compliance with some
other exemption under the Securities Act, none of which may be available for
resale of the Common Shares by you.  You recognize and acknowledge that, except
as set forth in this Agreement, the Company is under no obligation to register
the Common Shares, either pursuant to the Securities Act or the securities laws
of any state.

        5.  RESTRICTIVE LEGEND.  Each certificate representing Common Shares
shall, except as otherwise provided in this Section 5 or in Section 6, be
stamped or otherwise imprinted with a legend substantially in the following
form:

        "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933
        AND MAY NOT BE TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS IT HAS BEEN  
        REGISTERED UNDER THAT ACT OR AN EXEMPTION FROM REGISTRATION IS
        AVAILABLE.  THE HOLDER OF THIS SECURITY IS ENTITLED TO CERTAIN
        REGISTRATION RIGHTS SET FORTH IN A RESTRICTED SECURITIES AND
        REGISTRATION RIGHTS AGREEMENT DATED NOVEMBER __, 1994, A COPY OF WHICH
        MAY BE OBTAINED FROM THE SECRETARY OF THE CORPORATION."

Such certificates shall not bear such legend if in the opinion of counsel
satisfactory to the Company the securities being sold thereby may be publicly
sold without registration under the Securities Act or if such securities have
been sold pursuant to Rule 144 or an effective registration statement.

        6.  NOTICE OF PROPOSED TRANSFER.  Prior to any proposed transfer of any
Common Shares (other than under the circumstances described in Section 8), the
holder thereof shall give written notice to the Company of its intention to
effect such transfer. Each such notice shall describe the manner of the proposed
transfer and, if requested by the Company, shall be accompanied by an opinion of
counsel satisfactory to the Company to the effect that the proposed transfer may
be effected without registration under the Securities Act, whereupon the holder
of such security shall be entitled to transfer such security in accordance with
the terms of its notice; provided, however, that no prior notice or opinion of
counsel shall be required if the sale is made in compliance with Rule 144 or if
such transfer is to one or more partners of the transferor (in the case of a
transferor that is a partnership) (a "Distribution").  Each certificate for
Common Shares transferred as above provided shall bear the legend set forth in
Section 5, except that such certificate shall not bear such legend if (i) such
transfer is in
   77
                                      -4-


accordance with the provisions of Rule 144 (or any other rule permitting public
sale without registration under the Securities Act) or (ii) the opinion of
counsel referred to above is to the further effect that the transferee and any
subsequent transferee   (other than an affiliate of the Company) would be
entitled to transfer such securities in a public sale without registration under
the Securities Act.  The restrictions provided for in this Section 6 shall not
apply to securities which are not required to bear the legend prescribed by
Section 5 in accordance with the provisions of that Section.

        7.  REGISTRATION.  The Company agrees to cause a registration statement
under the Securities Act on an appropriate form (which shall be Form S-3, if
available) relating to all shares of Restricted Stock to be filed (i) no later
than December 20, 1994 in the case that the closing under the Acquisition
Agreement occurs on or before November 30, 1994 and (ii) within 30 days after
the date of any other such closing and further agrees to use all reasonable
efforts to cause such registration statement to be declared effective by the
Commission as soon as reasonably practicable.

        8.  REGISTRATION PROCEDURES.  In using its efforts to effect the
registration of any shares of Restricted Stock under the Securities Act, the
Company will, as expeditiously as possible:

        (a)  prepare and file with the Commission a registration statement with
respect to such securities on or before the date specified in Section 7 above
and use all reasonable efforts to cause such registration statement to become
effective on or before the date specified in Section 7 above and to remain
effective until the earlier of the sale of all Restricted Stock covered thereby
or two years after the Closing Date (as defined in the Acquisition Agreement),
PROVIDED, however, that the Company may suspend sales at any time under the
registration statement immediately upon notice to the undersigned at the last
known address of the undersigned, for a period or periods of time not to exceed
in the aggregate 60 days during any 12-month period, if there then exists
material, non-public information relating to the Company which, in the
reasonable opinion of the Company, would not be appropriate for disclosure
during that time;

        (b)  prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
the period specified in paragraph (a) above;

        (c)  furnish to each seller of Restricted Stock such number of copies of
the registration statement and each such amendment and supplement thereto (in
each case including exhibits) and the prospectus included therein (including
each
   78
                                      -5-


preliminary prospectus) as such persons reasonably may request in order to
facilitate the public sale or other disposition of the Restricted Stock covered
by such registration statement;

        (d)  use all reasonable efforts to register or qualify the Restricted
Stock covered by such registration statement under the securities or "blue sky"
laws of California and of such other jurisdictions as the sellers of Restricted
Stock reasonably shall request, provided, however, that the Company shall not
for any such purpose be required to qualify generally to transact business as a
foreign corporation in any jurisdiction where it is not so qualified or to
consent to general service of process in any such jurisdiction;

        (e)  use all reasonable efforts to have the Restricted Stock covered by
such registration statement subject to quotation on the Nasdaq National Market;
and

        (f) notify each seller of Restricted Stock under such registration
statement (at any time when a prospectus relating thereto is required to be
delivered under the Securities Act), of the happening of any event of which the
Company has knowledge as a result of which the prospectus contained in such
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances then existing, and promptly prepare and furnish to such seller a
reasonable number of copies of a prospectus supplemented or amended so that, as
thereafter delivered to the purchasers of such Restricted Stock, such prospectus
shall not include an untrue statement of material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances then existing.

        In connection with each registration hereunder, the sellers of
Restricted Stock will furnish to the Company in writing such information
requested by the Company with respect to themselves and the proposed
distribution by them as shall be necessary in order to assure compliance with
federal and applicable state securities laws.

        If the registration pursuant to Section 7 involves an underwritten
public offering, the Company and each seller who wishes to participate in such
underwriting agree to enter into a written agreement with the managing
underwriter in such form and containing such provisions as are customary in the
securities business for such an arrangement between such underwriter and
companies of the Company's size and investment stature.  Holders of Restricted
Stock shall not be required to participate in an underwriting; shares of
Restricted Stock held by such non- participating holders shall be registered as
required by this Agreement but shall not be included in the underwriting.

   79
                                      -6-

        9.  EXPENSES.  All expenses incurred by the Company in complying with
Sections 7 and 8, including, without limitation, all registration and filing
fees, printing expenses, fees and disbursements of counsel and independent
public accountants for the Company, fees and expenses (including reasonable fees
and disbursements of one counsel selected by the selling stockholders) incurred
in connection with complying with state securities or "blue sky" laws, fees of
the National Association of Securities Dealers, Inc., transfer taxes, fees of
transfer agents and registrars, and costs of issuance, but excluding any Selling
Expenses, are called "Registration Expenses".  All underwriting discounts (if
any) and selling commissions applicable to the sale of Restricted Stock are
called "Selling Expenses".

        The Company will pay all Registration Expenses in connection with the
registration statement under Section 7.  All Selling Expenses in connection with
the registration statement under Section 7 shall be borne by the participating
sellers in proportion to the number of shares sold by each.

        10.  INDEMNIFICATION AND CONTRIBUTION.

        (a)  In connection with the registration of the Restricted Stock under
the Securities Act pursuant to Section 7, the Company will indemnify and hold
harmless each seller of such Restricted Stock thereunder, its officers and
directors, each underwriter of such Restricted Stock thereunder and each other
person, if any, who controls such seller or underwriter within the meaning of
the Securities Act, against any losses, claims, damages or liabilities, joint or
several, to which such seller, officer, director, underwriter or controlling
person may become subject under the Securities Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon (i) any untrue statement or alleged untrue statement of
material fact contained in the registration statement under which such
Restricted Stock was registered under the Securities Act pursuant to Section 7,
any preliminary prospectus or final prospectus contained therein, or any
amendment or supplement thereto, (ii) the omission or alleged omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading or (iii) any violation by the Company or its agents of
any rule or regulation promulgated under the Securities Act applicable to the
Company or its agents and relating to action or inaction required of the Company
in connection with such registration, and the Company will reimburse each such
seller, each such officer and director, each such underwriter and each such
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action, provided, however, that the Company will not be liable in
any such case if any to the extent that any such loss, claim, damage or
liability arises out of or is based
   80
                                      -7-


upon an untrue statement or alleged untrue statement or omission or alleged
omission so made in conformity with information furnished by any such seller,
any such underwriter or any such controlling person in writing specifically for
use in such registration statement or prospectus.

        (b)  In connection with the registration of the Restricted Stock under
the Securities Act pursuant to Section 7, each seller of such Restricted Stock
thereunder, severally and not jointly, will indemnify and hold harmless the
Company, each person, if any, who controls the Company within the meaning of the
Securities Act, each officer of the Company who signs the registration
statement, each director of the Company, each underwriter and each person who
controls any underwriter within the meaning of the Securities Act, against all
losses, claims, damages or liabilities, joint or several, to which the Company
or such officer, director, underwriter or controlling person may become subject
under the Securities Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) the failure of such seller to comply with the provisions of Section 12
herein or (ii) any untrue statement or alleged untrue statement of any material
fact contained in the registration statement, any preliminary prospectus or
final prospectus contained therein, or any amendment or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse the Company and each such
officer, director, underwriter and-controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action, PROVIDED, HOWEVER,
that such seller will be liable hereunder in any such case if and only to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in reliance upon and in conformity with information pertaining to
such seller, as such, furnished in writing to the Company by such seller
specifically for use in such registration statement or prospectus.

        (c)  Promptly after receipt by an indemnified party hereunder of notice
of the commencement of any action, such indemnified party shall, if a claim in
respect thereof is to be made against the indemnifying party hereunder, notify
the indemnifying party in writing thereof, but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
such indemnified party other than under this Section 10 and shall only relieve
it from any liability which it may have to such indemnified party under this
Section 10 if and to the extent the indemnifying party is prejudiced by such
omission.  In case any such action shall be brought against any indemnified
party and it shall notify the
   81
                                      -8-


indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate in and, to the extent it shall wish, to assume and
undertake the defense thereof with counsel satisfactory to such indemnified
party, and, after notice from the indemnifying party to such indemnified party
of its election so to assume and undertake the defense thereof and the approval
by the indemnified party of the counsel chosen by the indemnifying party, the
indemnifying party shall not be liable to such indemnified party under this
Section 10 for any legal expenses subsequently incurred by such indemnified
party in connection with the defense thereof other than reasonable costs of
investigation and of liaison with counsel so selected, PROVIDED, HOWEVER, that,
if the defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be reasonable defenses available to it which are different
from or additional to those available to the indemnifying party or if the
interests of the indemnified party reasonably may be deemed to conflict with the
interests of the indemnifying party, the indemnified party shall have the right
to select a separate counsel and to assume such legal defenses and otherwise to
participate in the defense of such action, with the expenses and fees of such
separate counsel and other expenses related to such participation to be
reimbursed by the indemnifying party as incurred.

        (d)  In order to provide for just and equitable contribution to joint
liability under the Securities Act in any case in which either (i) any holder of
Restricted Stock exercising rights under this Agreement, or any controlling
person of any such holder, makes a claim for indemnification pursuant to this
Section 10 but it is judicially determined (by the entry of a final judgment or
decree by a court of competent jurisdiction and the expiration of time to appeal
or the denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 10 provides for
indemnification in such case, or (ii) contribution under the Securities Act may
be required on the part of any such selling holder or any such controlling
person in circumstances for which indemnification is provided under this Section
10; then, and in each such case, the Company and such holder will contribute to
the aggregate losses, claims, damages or liabilities to which they may be
subject (after contribution from others) in proportion to the relative fault of
the Company, on the one hand, and each holder, severally, on the other hand;
PROVIDED, HOWEVER, that, in any such case, no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) will be entitled to contribution from any person or entity who
was not guilty of such fraudulent misrepresentation.

        (e)  The indemnities provided in this Section 10 shall survive the
transfer of any Restricted Stock by such holder.

   82
                                      -9-


        11.  CHANGES IN COMMON STOCK.  If, and as often as, there is any change
in the Common stock by way of a stock split, stock dividend, combination or
reclassification, or through a merger, consolidation, reorganization or
recapitalization, or by any other means, appropriate adjustment shall be made in
the provisions hereof so that the rights and privileges granted hereby shall
continue with respect to the Common Stock as so changed.

        12.  SELLERS' CONDUCT.  You understand and agree as follows:

        (a)  You will carefully review the information concerning you contained
in the registration statement (if any) and will promptly notify the Company if

        (b)  You agree to sell your Common Shares only in the manner set forth

behalf of any of the parties hereto shall bind and inure to the benefit of the
respective successors and assigns of the parties hereto (including without
limitation transferees of any Restricted Stock), whether so expressed or not. 
If you are a partnership and transfer Common Shares in a Distribution, each such
transferee shall have the rights and obligations under this Agreement as if such
transferee were the distributing partnership, PROVIDED, that such transferee
executes a counterpart signature page to this Agreement.

        14.  REPRESENTATIONS.  You hereby represent and warrant to the Company
as follows:

     (a)  YOU UNDERSTAND THAT YOUR INVESTMENT IN THE SECURITIES IS ONE OF
          HIGH RISK.  YOU ARE ABLE TO BEAR THE TOTAL LOSS OF HIS INVESTMENT IN 
          THE COMPANY.

     (b)  YOU HAVE CONSULTED YOUR OWN ATTORNEY, ACCOUNTANT OR
          INVESTMENT ADVISOR WITH RESPECT TO THE INVESTMENT CONTEMPLATED HEREBY
          AND ITS SUITABILITY FOR YOU.  ANY SPECIFIC ACKNOWLEDGMENT SET FORTH
          BELOW WITH RESPECT TO ANY STATEMENT OR INFORMATION FURNISHED YOU TO
          SHALL NOT BE DEEMED TO LIMIT THE GENERALITY OF THIS REPRESENTATION AND
          WARRANTY.

     (c)  The Company has made available to you, during the course of this
          transaction and prior to the acquisition of the Common Stock and other
          rights to purchase Common Stock (collectively, the "Securities"), the
          opportunity to ask questions of and receive complete and correct
          answers from representatives of the Company concerning the terms and
          conditions of the Securities and to obtain any additional information
          relating to the financial condition and business of the Company.

     (d)  You understand that you must bear the economic risk of this
          investment until such time as the Securities are registered; that the
          Securities are not currently registered under the Securities Act, and,
          therefore, cannot be resold unless it is subsequently registered under
          the Securities Act or unless an exemption from such
          registration is available; that you are purchasing the Securities for
          investment for your account and not with any present view toward
          resale or other distribution thereof; that you agree not to resell or
          otherwise dispose of all or any part of the Securities, except as
          permitted by law, including, without limitation, any and all
          applicable provisions of the Acquisition Agreement and this Agreement
          and any regulations under the Securities Act and applicable state
          securities laws; that except as provided in the Acquisition Agreement
          and this Agreement, the Company is under no obligation to register the
          Securities under the Securities Act or any state securities law or to
          supply the information which may be necessary to enable you to sell
          the Securities; and that Rule 144 under the Securities Act is not now
          available as a basis for exemption from registration of any Securities
          hereunder.

     (e)  You have adequate means of providing for your current needs and
          personal contingencies and have no need for liquidity in connection
          with this investment in the   Securities.

   85
                                     -12-

    (f)   Your overall commitment to investments which are not readily
          marketable is not disproportionate to your net worth and your
          investment in the Securities will not cause such overall commitment to
          become excessive.  The acquisition of the Securities by you is
          consistent with your general investment objectives.

    (g)   If you are not an accredited investor (as defined in Rule 501(a)
          under the Securities Act and as set forth by any of the categories on
