                                      -5-
   10
tive rights or rights of first refusal on behalf of any person in existence
either on the date hereof or immediately prior to the Closing.

         2.4     No Conflict.  Subject to compliance with the HSR Act, and
except for the failure to obtain stockholder approval, if required, of the
issuance of the Shares in accordance with the policies of the NASD, the
execution and delivery of this Agreement and the Registration Rights Agreement
do not, and the consummation of the transactions contemplated hereby and
thereby will not, conflict with, or result in any violation of, or default
(with or without notice or lapse of time, or both), or give rise to a right of
termination, cancellation or acceleration of any obligation or to a loss of a
material benefit, under, any provision of the Certificate of Incorporation or
By-laws of the Company or any mortgage, indenture, lease or other agreement or
instrument, permit, concession, franchise, license, judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to the Company, its
properties or assets, the effect of which would have a material adverse effect
on the Company or materially impair or restrict its power to perform its
obligations as contemplated hereby or thereby.

         2.5     Accuracy of Reports.  All reports (the "SEC Reports") required
to be filed by the Company during the period from June 30, 1989 to the date of
this Agreement under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), copies of which have been furnished to the Purchasers, have
been duly filed, were in substantial compliance with the requirements of their
respective





                                      -6-
   11
forms, were complete and correct in all material respects as of the dates at
which the information was furnished, and none contained (as of such dates) any
untrue statement of a material fact nor omitted to state a material fact
necessary in order to make the statements made therein, in light of the
circumstances in which made, not misleading.

         2.6     Financial Statements and Changes.  The Company has delivered
to the Purchasers consolidated balance sheets as of June 30, 1989 and 1990 and
the related statements of operations, stockholders' equity and changes in
financial position and notes thereto for the fiscal years ended on June 30,
1988, 1989 and 1990, all of which are accompanied by the related audit opinion
of the Company's independent certified public accountants, Ernst & Young (or
its predecessor) (collectively, the "Financial Statements").  The Financial
Statements, with the notes thereto, have been prepared in accordance with
generally accepted accounting principles applied on a consistent basis
throughout the fiscal years covered by such statements (except as may be stated
in the notes to such statements or the related report of independent
accountants) and present fairly the Company's financial condition and results
of operations and changes in financial position as of the dates and for the
fiscal years indicated.  Except as otherwise disclosed herein, in the Financial
Statements or in the SEC Reports, since June 30, 1990, there has not been:

                 (a)      any change in the assets, liabilities, financial
condition or operations of the Company from that reflected in the





                                      -7-
   12
Financial Statements except changes in the ordinary course of business which
have not been, either in any individual case or in the aggregate, materially
adverse;

                 (b)      any change, except in the ordinary course of
business, in the contingent obligations of the Company, whether by way of
guaranty, endorsement, indemnity, warranty or otherwise;

                 (c)      any damage, destruction or loss, whether or not
covered by insurance, materially and adversely affecting the properties or
business of the Company;

                 (d)      any declaration or payment of any dividend (other
than the rights distribution described in Section 2.2 hereof) or other
distribution of the assets of the Company;

                 (e)      any labor organization activity; or

                 (f)      to the best of the Company's knowledge, any other
event or condition of any character which has materially and adversely affected
the Company's assets, liabilities, financial condition or operations.

         2.7     Registration Rights.  Except as set forth in this Agreement or
the Registration Rights Agreement, and except for the continuing practice of
the Company to register its employee stock plans on Form S-8, the Company is
not under any obligation to register any of its presently outstanding
securities or any of its securities which may hereafter be issued.

         2.8     Governmental Consent, etc.  No consent, approval or
authorization of or designation, declaration or filing with any governmental
authority on the part of the Company is required in





                                      -8-
   13
connection with the valid execution and delivery of this Agreement, or the
offer, sale or issuance of the Shares, or the consummation of any other
transaction contemplated hereby, except the filing of such forms with the
United States Department of Justice and the Federal Trade Commission as shall
be required by the HSR Act and the expiration of any waiting periods thereunder
and such filings as may be required to be made with the Securities and Exchange
Commission ("SEC") and the NASD and filings, if any, to be made in compliance
with applicable blue sky requirements.

         2.9     Disclosure.  No representation or warranty of the Company
contained in this Agreement or the exhibits attached hereto (when read together
and taken as a whole) contains any untrue statement of a material fact or omits
to state a material fact necessary in order to make the statements contained
herein or therein, in light of the circumstances under which they were made,
not misleading.

         2.10    Amendment to Rights Agreement.  All action required under the
Rights Agreement to amend the Rights Agreement has been taken (or will have
been taken prior to the Closing) so that the issuance of the Shares shall not
cause either of the Purchasers to become an "Acquiring Person" or cause a
"Shares Acquisition Date", "Distribution Date" or "Triggering Event" to occur
(each as defined in the Rights Agreement).

                                  SECTION 3

                                      -9-
   14
         Each of the Purchasers hereby represents and warrants to the Company,
as to itself alone and not jointly with the other Purchaser, as follows:

         3.1     Investment.  The Purchaser will acquire the Shares and any
other shares purchased from the Company pursuant to this Agreement for
investment for its own account, not as a nominee or agent, and not with a view
to, or for resale in connection with, any distribution thereof.  Purchaser
understands that the Shares and any other shares purchased by it from the
Company pursuant to this Agreement have not been, and will not be, registered
(unless sold in connection with a public offering by the Company) under the
Securities Act by reason of a specific exemption from the registration
provisions of the Securities Act which depends upon, among other things, the
bona fide nature of the Purchaser's investment intent and the accuracy of the
Purchaser's representations as expressed herein.

         3.2     Organization.  The Purchaser is a corporation duly organized
and validly existing and in good standing under the laws of the state of its
incorporation, with all requisite corporate power and authority to own, lease
and operate its properties and assets and to carry on its business as presently
conducted and as proposed to be conducted.

         3.3     Authority.  The Purchaser has all corporate right, power and
authority to enter into this Agreement and the Registration Rights Agreement
and to consummate the transactions contemplated hereby and thereby.  The
execution and delivery of this Agreement





                                      -10-
   15
and the Registration Rights Agreement by the Purchaser and the consummation by
the Purchaser of the transactions contemplated hereby and thereby have been
duly authorized by all necessary corporate action on behalf of the Purchaser.
This Agreement and the Registration Rights Agreement have been duly executed
and delivered by the Purchaser and constitute legal, valid and binding
obligations of the Purchaser, enforceable in accordance with their respective
terms, subject to laws of general application relating to bankruptcy,
insolvency and the relief of debtors and rules of law governing specific
performance, injunctive relief or other equitable remedies, and to limitations
of public policy as they may apply to Section 4 of the Registration Rights
Agreement.  Subject to compliance with the HSR Act and such filings as may be
required to be made with the SEC and any exchange or quotation system on which
the Purchaser's securities are listed or designated, the execution and delivery
of this Agreement and the Registration Rights Agreement do not, and the
consummation of the transactions contemplated hereby and thereby will not,
conflict with or result in any violation of any obligation under any provision
of the Certificate or Articles of Incorporation or By-laws of the Purchaser or
any judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to the Purchaser.

         3.4     Government Consents, etc.  No consent, approval or
authorization of or designation, declaration or filing with any governmental
authority on the part of the Purchaser is required in connection with the valid
execution and delivery of this Agreement,





                                      -11-
   16
or the offer, sale or issuance of the Shares or the consummation of any other
transaction contemplated hereby, except the filing of such forms with the
United States Department of Justice and the Federal Trade Commission as shall
be required by the HSR Act and the expiration of any waiting periods thereunder
and such filings as may be required to be made with the SEC and any exchange or
quotation system on which the Purchaser's securities are listed or principally
traded.

         3.5     Investigation.  The Purchaser has had a reasonable opportunity
to discuss the Company's business, management and financial affairs with the
Company's management and the Purchaser has received satisfactory responses from
management of the Company to the Purchaser's inquiries.

         3.6     Financing.  The Purchaser has the funds, or has written
commitments from responsible financial institutions, to provide the Company
with the funds necessary to consummate the transactions to occur at the
Closing.


                                   SECTION 4

                                   SECTION 6

                            Covenants of the Company

         Until the termination of this Agreement in accordance with Section 9.2
hereof or the particular covenant, as the case may be:





                                      -15-
   20
         6.1     No Objection.  In the case of either Purchaser, provided the
Purchaser is in compliance with and has performed all covenants, agreements and
conditions contained in this Agreement to be performed by the Purchaser, the
Company shall not interpose any objection or take any legal action as a
plaintiff in connection with the acquisition by the Purchaser of such number of
shares of Common Stock as is permitted to be owned by the Purchaser pursuant to
this Agreement.

         6.2     Notice of Acquisition.

                 (a)      The Company shall give the Purchasers prompt notice
of the receipt by the Company of (i) any written notice from any person or
group couched in such terms as to put the Company reasonably on notice of the
likelihood that such person or group has acquired or is proposing to acquire
any shares of Voting Stock which results in, or, if successful, would result
in, such person or group owning or having the right to acquire more than 5% of
the Total Voting Power of the Company, (ii) any notice under the HSR Act, and
(iii) any statement on Schedule 13D or Schedule 14D-1 (or any successor
schedule or form to such schedules) under the Exchange Act.

                 (b)      In the event the Company should engage or propose to
engage in any significant discussions of any proposed offer from any person
relating to any merger, consolidation or acquisition involving the sale or
transfer of all or substantially all of the assets of, or any substantial
equity interest in, the Company, the Company will advise the Purchaser of such
discussions at the





                                      -16-
   21
earliest opportunity, but only to the extent the giving of such advice, in the
opinion of legal counsel to the Company, is not inconsistent with the fiduciary
obligations of the Company's Board of Directors.

         6.3     Sale of Additional Shares.  The Company shall take such action
as is reasonably necessary, subject to compliance with applicable law, to issue
and sell to the Purchasers any additional shares which the Purchasers shall be
entitled to purchase from the Company pursuant to this Agreement.

         6.4     Membership on the Board of Directors.

                 (a)      Upon the Closing of the transactions contemplated
hereby, the Company shall permit each of the Purchasers, upon its request, to
have an observer designated by the Purchaser, reasonably satisfactory to the
Company, present at all meetings of the Company's Board of Directors, including
any meetings of any committee designated by the Board.  The Company's
obligation to so permit an observer designated by a Purchaser shall terminate
if such Purchaser's percentage interest in the Total Voting Power of the
Company, after adjustment for the exercise, or failure to exercise, of the
right to maintain by such Purchaser pursuant to Section 7.8 below (except in
the event of a delaying notice pursuant to Section 7.8(e)), is less than 5%
(even if such Purchaser's percentage interest should subsequently increase for
any reason to 5% or more).  A Purchaser may not exercise its right to
representation on the Company's Board of Directors under paragraph (b) below
for so





                                      -17-
   22
long as the Purchaser shall have designated an observer as permitted herein.

                 (b)      Upon the Closing of the transactions contemplated
hereby, the Company shall cause to be appointed to the Company's Board of
Directors, upon the request of a Purchaser, any person designated by such
Purchaser and approved by the Company, which approval shall not unreasonably be
withheld.  Any such person shall serve until his successor has been duly
elected and qualified.  Thereafter, the Company shall include in the slate of
nominees recommended by the Company's Board of Directors or management to
stockholders for election as directors at each annual meeting of stockholders
of the Company any person designated pursuant to this paragraph, or such
substitute as may be designated by a Purchaser and who is reasonably acceptable
to the Company, and the Company shall use its best efforts to cause the shares
for which the Company's management or directors hold proxies or are otherwise
entitled to vote to be voted in favor of the election of such designee to the
extent necessary to ensure his election assuming that all Voting Stock
beneficially owned by the Purchaser is voted for such designee.  In the event
that any such designee shall cease to serve as a director for any reason, the
Company shall use its best efforts to fill such vacancy by a designee of the
Purchaser reasonably acceptable to the Company.  The Company shall not
unreasonably withhold its acceptance of any such designee.  Notwithstanding the
foregoing, the Company's obligation under this paragraph shall terminate as to
a Purchaser if the percentage





                                      -18-
   23
interest of such Purchaser in the Total Voting Power of the Company, after
adjustment for the exercise, or failure to exercise, of the right to maintain
by such Purchaser pursuant to Section 7.8 below (except in the event of a
delaying notice pursuant to Section 7.8(e)) is less than 8% (even if such
Purchaser's percentage interest should subsequently increase for any reason to
8% or more).  A Purchaser may not exercise its right to have an observer attend
meetings of the Company's Board of Directors under paragraph  (a) above for so
long as the Purchaser shall have exercised the right to Board representation as
permitted herein.

                 (c)      Any designee of a Purchaser, whether acting as an
observer or as a director on the Board of Directors, shall be entitled to
except himself from all discussions and deliberations of the Board of Directors
of the Company (or any committee constituted by the Board) concerning
competitors of the Purchaser or relationships between the Company and either of
the Purchasers.  Upon notice to a Purchaser's designee, the Company may refrain
from sending or providing to the Purchaser, or the Purchaser may refuse to
receive, any information otherwise disseminated to the directors of the Company
concerning competitors of the Purchaser or relationships between the Company
and either of the Purchasers.  The Company shall not be obligated to compensate
a designee-director of a Purchaser on the same terms as other outside directors
(except for any designee-director of the other Purchaser) but shall provide all
rights and benefits of indemnity to such designee-director as are provided such
other directors.

   24
         6.5     Equity Method Accounting.  If either of the Purchasers desires
at some date after the Closing to account for its investment in the Company
pursuant to the equity method, the Company shall furnish to such Purchaser all
information that is required by generally accepted accounting principles to
enable such Purchaser so to account, to the extent reasonably available to the
Company.  To the extent requested by such Purchaser, the Company shall provide
information, to the extent reasonably available, regarding the Company to, and
otherwise cooperate with, such Purchaser so as to enable such Purchaser to
prepare financial statements in accordance with generally accepted accounting
principles and to comply with its reporting requirements under applicable
United States securities laws and regulations.

         6.6     Registration Rights.  The Company will comply with the
provisions regarding registration rights contained in the Registration Rights
Agreement attached as Exhibit A hereto.

         6.7     HP Marketing Agreement.  On or before the execution date
hereof, the Company will have entered in to a marketing agreement with HP on
terms mutually acceptable to the Company and HP.

         6.8     EDS Agreements.  On or before the execution date hereof, "the
Company shall have executed and delivered to EDS an amendment to that certain
Software License and Services Agreement dated March 29, 1990 between the
Company and EDS on terms mutually acceptable to the Company and EDS, which
amendment will include agreements regarding EDS' designation by the Company as
a preferred systems integrator of Company software products.  In addition, the
Company





                                      -20-
   25
and EDS agree to continue negotiating in good faith and expeditiously the terms
of a facilities management contract as contemplated by that certain letter of
intent dated August 8, 1990 between the Company and EDS, it being understood
that such contract will be executed by October 15, 1990.

         6.9     Inspection Rights.

                 (a)      Between the date hereof and the Closing, upon the
request of a Purchaser, the Company shall permit the Purchaser and any of its
authorized agents, at the Purchaser's expense, to visit and inspect any of the
properties of the Company, to examine its books of account and records relating
to the business and affairs of the Company, and to discuss the affairs,
finances and accounts with the Company's officers and other principal
executives, all at such reasonable times as may be reasonably requested.

                 (b)      Until the termination of this Agreement in accordance
with Section 9.2 hereof, the Company shall furnish to each of the Purchasers,
promptly upon filing thereof with the SEC, copies of all reports and documents
required to be filed by the Company with the SEC (other than preliminary
material) under the Securities Act and Exchange Act and the rules and
regulations thereunder.


                                   SECTION 7

                          Covenants of the Purchasers 

         Until the termination of this Agreement in accordance with Section 9.2
hereof:





                                      -21-
   26
         7.1     Limitation on Ownership of Voting Stock.  Neither of the
Purchasers shall (and neither Purchaser shall permit any of its subsidiaries
to) acquire, directly or indirectly, beneficial ownership of any Voting Stock,
any securities convertible into or exchangeable for Voting Stock, or any other
right to acquire Voting Stock (except, in any case, as provided herein or by
way of stock dividends or other distributions or offerings made available to
holders of any Voting Stock generally) or authorize or make a tender, exchange
or other offer, without the written consent of the Company, if the effect of
such acquisition or offer would be to increase the Voting Power of all Voting
Stock then owned by such Purchaser or which it has a right to acquire to more
than the percentage of the Total Voting Power of the Company which such
Purchaser is entitled to hold at such time as provided in this Section 7.1:

                 (a)      EDS and HP shall be entitled to hold Voting Stock up
to, and not to exceed except as permitted by this Agreement, 22% and 11%,
respectively, of the Total Voting Power of the Company.  Subject to such
limitation, shares of Voting Stock not acquired by a Purchaser from the Company
under Section 7.8 may be acquired by such Purchaser in the open market or from
third parties.

                 (b)      Either of the Purchasers may acquire Voting Stock
without regard to the limitations in this Section 7.1 if a tender offer is made
(as evidenced by the filing with the SEC of a Schedule 14D-1 (or any successor
schedule or form promulgated or adopted for such purpose by the SEC) and the
actual dissemination





                                      -22-
   27
of tender offer materials to security holders) by another person or group to
purchase or exchange for cash or other consideration any Voting Stock which, if
successful, would result in such person or group owning or having the right to
acquire shares of Voting Stock with aggregate Voting Power of at least 40% of
the Total Voting Power of the Company then in effect; provided, however, that
this provision shall not be effective until such time as the Purchaser in the
exercise of the reasonable judgment of its Board of Directors, after
consultation with its investment bankers and those of the Company (who shall
make themselves promptly available) shall reasonably conclude that such tender
offeror can finance such tender offer.  If an offer or proposed acquisition is
made by any person or group which pursuant to this Section 7.1(b) releases a
Purchaser from the limitations set forth herein, which offer or proposed
acquisition subsequently expires, is enjoined or terminated prior to any
purchases thereunder or is otherwise withdrawn, then the limitations of this
Section 7.1(b) shall be reimposed, except that the Purchaser shall not be
obligated to dispose of any Voting Stock acquired of record or beneficially
during the pendency of such offer or proposed acquisition.

                 (c)      Either of the Purchasers may acquire Voting Stock (or
rights to acquire Voting Stock) without regard to the limitations in this
Section 7.1 if it is publicly disclosed or such Purchaser otherwise learns that
another person or group has acquired any Voting Stock (or rights to acquire
Voting Stock), without the affirmative support of the Company's Board of Direc-





                                      -23-
   28
tors, which results in such person or group owning or having the right to
acquire Voting Stock with Total Voting Power of not less than 20%; provided,
however, that the Purchasers shall have no rights under this paragraph if the
person acquiring Voting Stock (or rights to acquire Voting Stock) is the
Affiliate.

                 (d)      No Purchaser will be obligated to dispose of any
shares of Voting Stock if the aggregate percentage ownership of such Purchaser
in the Total Voting Power of the Company is increased as a result of a
recapitalization of the Company or a repurchase of securities by the Company or
any other action taken by the Company or its affiliates, but the Purchasers
shall not acquire any additional Voting Stock unless such acquisition would
otherwise be permitted under this Agreement.  If, after either or both of the
Purchasers have acquired Voting Stock in response to the acquisition of Voting
Stock by another person or group, as permitted by this Section 7.1, then such
Purchasers shall not be obligated to dispose of any shares of Voting Stock if
the aggregate percentage ownership of such third party or group is thereafter
reduced.

         7.2     Voting.  Each Purchaser shall take such action as may be
required so that all shares of Voting Stock owned by the Purchasers are voted
for nominees to the Board of Directors of the Company in accordance with the
recommendation of the Board of Directors consistent with the provisions of
Section 6.4.  Unless the Company otherwise consents in writing, each Purchaser
shall take such action as may be required so that all shares of Voting Stock
owned





                                      -24-
   29
by the Purchaser are voted in accordance with the recommendations of the Board
of Directors on all other matters to be voted on by holders of Voting Stock in
not less than the same proportion as the votes cast by the other holders of
Voting Stock (other than the other Purchasers) with respect to such matters;
provided, however, that Voting Stock owned by a Purchaser may be voted as the
Purchaser determines in its sole discretion on any Significant Event (as
defined in Section 9.1 below) presented to be voted on by the holders of Voting
Stock.  Each Purchaser, as the holder of shares of Voting Stock, shall be
present, in person or by proxy, at all meetings of stockholders of the Company
so that all shares of Voting Stock beneficially owned by the Purchasers may be
counted for the purposes of determining the presence of a quorum at such
meetings.

         7.3     Voting Trust, etc.  No Purchaser shall deposit any shares of
Voting Stock in a voting trust or, except as otherwise provided herein, subject
any Voting Stock to any arrangement or agreement with respect to the voting of
such Voting Stock.

         7.4     Solicitation of Proxies.  Without the Company's prior written
consent, no Purchaser shall solicit proxies with respect to any Voting Stock,
or become a "participant" in any "election contest" (as such terms are used in
Rule 14a-11 of Regulation 14A under the Exchange Act relating to the election
of directors of the Company); provided, however, that a Purchaser shall not be
deemed to be a "participant" by reason of the exercise of any right permitted
by Section 6.4.





                                      -25-
   30
         7.5     Acts in Concert with Others.  No Purchaser shall join a
partnership, limited partnership, syndicate or other group, or otherwise act in
concert with any third person, for the purpose of acquiring, holding, or
disposing of Voting Stock.

         7.6     Restrictions on Transfer of Voting Stock.  No Purchaser shall,
directly or indirectly, sell or transfer any Voting Stock except (i) to the
Company or any person or group approved by the Company; or (ii) to any
subsidiary of the Purchaser, all of the Voting Stock of which is owned by the
Purchaser (a "Wholly Owned Subsidiary"); or (iii) pursuant to a bona fide
public offering (which shall be structured to distribute such shares or rights
through an underwriter or otherwise in such a manner, to the best ability of
the Purchaser or Purchasers, as will not result in a sale or sales, by either
or both of the Purchasers, of beneficial ownership of Voting Stock with
aggregate Voting Power of 5% or more of the Total Voting Power of the Company
then in effect being transferred to a single person or group) registered under
the Securities Act of either Voting Stock or securities exchangeable or
exercisable for Voting Stock or pursuant to a rights offering or a dividend or
other ratable distribution to shareholders of the Purchaser; or (iv) pursuant
to Rule 144 under the Securities Act (but only to the extent the sale or
transfer of Voting Stock at any time is in compliance with the volume
limitations under paragraph (e) thereunder); or (v) subject to the Company's
right of first refusal as set forth in Section 8.1 hereof, in transactions not
otherwise described herein so long as such transactions do not,





                                      -26-
   31
directly or indirectly, result, to the best knowledge of the Purchaser, after
reasonable inquiry, in any single person or group owning or having the right to
acquire Voting Stock with aggregate Voting Power of 5% or more of the Total
Voting Power of the Company then in effect; or (vi) in response to (1) an offer
to purchase or exchange for cash or other consideration any Voting Stock (a)
which is made by or on behalf of the Company or (b) which is made by another
person or group and is not opposed by the Board of Directors of the Company
within the time such Board is required, pursuant to regulations under the
Exchange Act, to advise the Company's stockholders of such Board's position on
such offer, or (2) subject to the Company's right of first refusal as set forth
in Section 8.2, any other offer made by another person or group to purchase or
exchange for cash or other consideration any Voting Stock which, if successful,
would result in such person or group owning or having the right to acquire
Voting Stock with aggregate Voting Power of more than 40% of the Total Voting
Power of the Company then in effect.

         7.7     Confidential Information.  The Company may from time to time
pursuant to this Agreement (including pursuant to Section 6.4 hereof) disclose
to a Purchaser certain strategic, technical, financial or other information
which the Company deems to be confidential.  The Purchaser agrees that all such
confidential information will be kept confidential unless such information (i)
is already lawfully in the Purchaser's possession, (ii) becomes generally
available to the public other than as a result of a





                                      -27-
   32
disclosure by the Purchaser or any of its directors, officers, employees,
agents or advisors, (iii) becomes available to the Purchaser on a
non-confidential basis from a source other than the Company or its advisors,
provided that such source is not known to the Purchaser to be bound by a
confidentiality agreement with or other obligation of secrecy to the Company or
another party, (iv) is required to be disclosed by the Purchaser by operation
of law, (v) is disclosed by the Purchaser with the Company's prior written
approval, or (vi) has been held by the Purchaser for not less than three (3)
years from the date of receipt, provided, that the confidentiality of
confidential information furnished to an individual designated by the Purchaser
as an observer or director on the Company's Board of Directors (and not
additionally furnished to other representatives of the Purchaser) shall not
lapse by virtue of this clause.  Notwithstanding anything to the contrary, the
Purchaser may disclose such confidential information to its directors,
officers, employees, agents or advisors so long as it takes appropriate
measures to protect the confidentiality thereof, which measures shall include
at least the same degree of care that the Purchaser uses to protect its own
confidential information of a similar nature.  In the event that a Purchaser or
any of its representatives is requested or required to disclose any of the
confidential information referred to above, the Purchaser will provide the
Company with prompt notice of such request or requirement so that the Company
may seek a protective order or waive the Purchaser's compliance with this
Section 7.7, as





                                      -28-
   33
appropriate.  Each Purchaser further acknowledges and understands that any
information so obtained which may be considered "insider" non-public
information will not be utilized by the Purchaser in connection with purchases
and/or sales of the Company's securities except in compliance with applicable
state and federal securities laws.

         7.8     Right to Maintain.

                 (a)      If the percentage interest of a Purchaser in the
Total Voting Power of the Company is at or less than the Standstill Limit and
is reduced as a result of an issuance by the Company of any Voting Stock
(including any issuance following conversion of any security convertible into
or exchangeable for Voting Stock or upon exercise of any option, warrant or
other right to acquire any Voting Stock), the Purchaser shall have the right to
purchase from the Company for cash upon the terms set forth in this Section 7.8
that number of shares of Voting Stock which, if purchased by the Purchaser,
would result in the Purchaser's retaining the percentage interest in the Total
Voting Power of the Company held by the Purchaser immediately prior to such
reduction of the Purchaser's interest.

                 (b)      The purchase price per share at which the Purchaser
shall be entitled to purchase Voting Stock under this Section 7.8 shall be
determined as follows:

                          (i)     If the event giving rise to the Purchaser's
rights is one or more issuances of Voting Stock (including any issuance
resulting from the conversion or exercise of any security





                                      -29-
   34
or other right to acquire Voting Stock) pursuant to the Company's present or
future stock option, stock purchase or other stock plans for the benefit of
employees, directors, consultants or others, the price shall be the Average
Market Price per share of Voting Stock determined as of the date of the
issuance and sale of such Voting Stock.

                          (ii)    If the event giving rise to the Purchaser's
rights is a sale or issuance of Voting Stock for cash or property, including
without limitation, for securities or assets or by way of merger in connection
with the acquisition of another company, and is not treated under paragraph
7.8(b)(i) above, the price shall be the price per share specified in the
agreement relating to such issuance or, if no such price is specified, the
Average Market Price per share of Voting Stock determined as of the date of
issuance and sale of such Voting Stock;

                          (iii)   If the event giving rise to the Purchaser's
right is an issuance of Common Stock upon conversion of any security
convertible into or exchangeable for Common Stock or upon exercise of any
option, warrant or right to acquire any Common Stock, and is not treated under
paragraph 7.8(b)(i) or (ii) above, the price shall be the Average Market Price
per share of Common Stock determined as of the date of such conversion or
exercise.

                          (iv)    If the event giving rise to the Purchaser's
rights is an underwritten public offering or an institutional private
placement, the price shall be the price per share at which the Voting Stock was
sold by the Company.





                                      -30-
   35
                          (v)     In all other cases, the price shall be the
Average Market Price per share of Voting Stock determined as of the date of the
issuance and sale of such Voting Stock.

                 (c)      The Company shall notify the Purchaser by written,
dated notice not later than ten (10) business days after an issuance giving
rise to the Purchaser's rights under this Section 7.8 and, if such offer is
accepted in writing within thirty (30) days of such offer (except as provided
in the next sentence), effect the sale of the securities to the Purchaser in
accordance with this paragraph.  If the event giving rise to the Purchaser's
rights is an underwritten public offering or an institutional private placement
of securities by the Company, and if the Company gives the Purchaser notice of
such offering at least fifteen (15) days in advance of the effective date of
the offering, then unless the Purchaser notifies the Company of its irrevocable
acceptance of such offer within the first ten (10) days of such 15-day period
(for the purpose of permitting the Company to disclose the fact of the
Purchaser's intention in the prospectus relating to such underwritten public
offering or institutional private placement), the Company shall be under no
obligation to sell securities to the Purchaser under this Section 7.8 as a
result of such underwritten public offering or institutional private placement.

                 (d)      The purchase and sale of any shares of Voting Stock
pursuant to any offer made under this Section 7.8 that is accepted by the
Purchaser shall take place at 10:00 a.m. on the third business day following
the expiration or early termination of all





                                      -31-
   36
waiting periods imposed on such purchase and sale by the HSR Act and the
receipt of all other applicable regulatory approvals, or, if no waiting period
is imposed on such purchase and sale by the HSR Act, on the third business day
following the Purchaser's acceptance of such offer and compliance with
applicable laws and regulations, at the offices of the Company located at the
address set forth in this Agreement, or at such other time and place as the
Company and the Purchaser may agree.  The purchase price shall be payable by
wire transfer in same day funds.  The Company and the Purchaser shall comply
with all federal and state laws and regulations and requirements of the NASD
(subject to the right of the Company to elect to decline to comply with any
applicable stockholder approval requirement if the only effect thereof is a
loss of status of the Voting Stock as a National Market System-designated
security), or any securities exchange on which the Company's securities may
then be listed, applicable to any purchase and sale of shares of Voting Stock
under this Section 7.8.

                 (e)      Notwithstanding the foregoing, if any issuance of
securities requiring the Company to make an offer of Voting Stock to a
Purchaser under this Section 7.8 shall be for a number of securities
representing less than 2% of the Total Voting Power of the Company immediately
following such issuance, the Company shall have the right to delay giving the
notice otherwise required by Section 7.8(c) until the earlier of (i) the next
issuance which, together with all issuances after which notice was delayed
pursuant to this sentence, shall represent an aggregate of 2% or more of the





                                      -32-
   37
Total Voting Power of the Company then in effect or (ii) the 45th calendar day
preceding the last day of the Company's fiscal year for accounting purposes,
and, thereupon, the Company shall give such notice with respect to all shares
of Voting Stock which it shall be obligated to offer to sell to the Purchaser
at the price determined in Section 7.8(b) hereof and which shall not have been
the subject of a previous notice pursuant to Section 7.8(c); provided, however,
that the Purchaser shall have the right to request the purchase of all shares
of Voting Stock which the Purchaser has a right to acquire under this Section
7.8 at any time (a) if a bona fide tender or exchange offer is made by another
person or group to purchase or exchange for cash or other consideration any
Voting Stock from the Company's stockholders generally, or (b) upon the
Company's publication or setting of a record date of its stockholders; and, in
either such event and upon the receipt of such request, the Company shall use
its reasonable efforts to issue all such shares to the Purchaser pursuant to
the provisions of this Section 7.8.

                 (f)      If a Purchaser sells any Voting Stock, or fails to
exercise its right to acquire additional Voting Stock as permitted in this
Section 7.8 within the time period prescribed, the percentage ownership in the
Total Voting Power of the Company which such Purchaser is then entitled to
maintain under this Section 7.8 shall be reduced to the Purchaser's percentage
ownership that results immediately following such sale or failure to exercise.





                                      -33-
   38
                 (g)      The Purchaser shall forfeit all rights under this
Section 7.8 if at any time the Purchaser's Voting Stock represents less than
five percent (5%) (inclusive of the shares the Purchaser is entitled to
purchase under an outstanding offer pursuant to this Section 7.8) of the Total
Voting Power the Company (even if such Purchaser's percentage interest should
subsequently increase for any reason to 5% or more).

         7.9     Acquisition of Stock.  Each Purchaser shall advise management
of the Company as to the Purchaser's general plans to acquire any additional
shares of Voting Stock, or rights thereto, reasonably in advance of any such
acquisitions; provided, however, that if advance notice of acquisitions of
Voting Stock, or rights thereto, in the open market is not reasonably
practicable, notice of any such acquisition shall be made promptly following
such acquisition.  All of such Purchaser's purchases of Voting Stock shall be
in compliance with applicable laws and regulations and the provisions of this
Agreement.


                                   SECTION 8

                         Company Right of First Refusal

         8.1     Right of First Refusal.  Prior to making any sale or transfer
of Voting Stock of the Company pursuant to Section 7.6(v), each Purchaser shall
give the Company the opportunity to purchase such Voting Stock in the following
manner:

                 (a)      The Purchaser shall give notice (the "Transfer
Notice") to the Company in writing of such intention specifying the





                                      -34-
   39
names of the proposed purchasers or transferees, the amount of Voting Stock
proposed to be sold or transferred, the proposed price per share therefor (the
"Transfer Price") and the other material terms upon which such disposition is
proposed to be made.

                 (b)      The Company shall have the right, exercisable by
written notice given by the Company to the Purchaser within twenty (20) days
after receipt of such Transfer Notice, to purchase all but not part (unless
otherwise agreed) of the Voting Stock specified in such Transfer Notice for
cash per share equal to the Transfer Price.

                 (c)      If the Company exercises its right of first refusal
hereunder, the closing of the purchase of the Voting Stock with respect to
which such right has been exercised shall take place within ninety (90) days
after the Company gives notice of such exercise, which period of time shall be
extended if necessary to comply with applicable securities laws and
regulations.  Upon exercise of its right of first refusal, the Company and the
Purchaser shall be legally obligated to consummate the purchase contemplated
thereby and shall use their best efforts to secure any approvals required in
connection therewith.

                 (d)      If the Company does not exercise its right of first
refusal hereunder within the time specified for such exercise, the Purchaser
shall be free, during the period of 90 days following the expiration of such
time for exercise, to sell the Voting Stock specified in such Transfer Notice
on terms no less favorable to the Purchaser than the terms specified in such
Transfer Notice.  The





                                      -35-
   40
transferee shall acquire such Voting Stock free from any of the provisions of
this Agreement, provided, however, such Voting Stock shall be subject to any
restrictions imposed under applicable securities laws and regulations.

         8.2     Tender Offer Sale.  Prior to making any sale or exchange of
Voting Stock pursuant to Section 7.6(vi)(2) in response to a tender or exchange
offer, each Purchaser shall give the Company the opportunity to purchase such
Voting Stock in the following manner:

                 (a)      The Purchaser shall give notice (the "Tender Notice")
to the Company in writing of such intention no later than ten (10) days prior
to the latest time (as the same may be extended) by which Voting Stock must be
tendered in order to be accepted pursuant to such offer or to qualify for any
proration applicable to such offer (the "Tender Date"), specifying the amount
of Voting Stock proposed to be tendered.  For purposes hereof, a tender offer
to purchase Voting Stock shall be deemed to be an offer at the price specified
therein, without regard to any provisions thereof with respect to proration or
conditions to the offeror's obligation to purchase (assuming such conditions
are not impossible of performance when the offer is made, without giving effect
to the Company's right of first refusal).

                 (b)      If the Tender Notice is given, the Company shall have
the right, exercisable by giving notice (the "Purchase Notice") to the
Purchaser at least three (3) business days prior to the Tender Date, to
purchase all but not part of the Voting Stock specified in the Tender Notice
for cash.  If the Company exercises





                                      -36-
   41
such right by giving such notice, the closing of the purchase of such Voting
Stock shall take place on the fifth business day after the tender offer is
consummated, or such earlier time as the Company shall agree; provided that the
Company's obligation to purchase such shares of Voting Stock following delivery
of any Purchase Notice shall be contingent on consummation of the tender offer
referred to in the corresponding Tender Notice.  As a condition to the
effectiveness of any exercise by the Company of its rights to purchase under
this Section 8.2, at the time the Company delivers a Purchase Notice, it shall
have provided for the payment to the Purchaser of the purchase price for such
shares by an escrow of funds, letter of credit facility, bank guarantee or
similar arrangement reasonably acceptable to the Purchaser.  If the purchase
price specified in the tender offer includes any property other than cash, the
value of any property included in the purchase price, for purposes of
determining the amount to be provided for by the Company pursuant to the
preceding sentence only, shall be determined by a nationally recognized
investment banking firm selected by the Company.  Upon exercise of the right of
first refusal (including provision for payment as described above), the Company
and the Purchaser shall be legally obligated to consummate the purchase
contemplated thereby and shall use their best efforts to secure any approvals
required in connection therewith, subject only to consummation of the tender
offer referred to in the corresponding Tender Notice.





                                      -37-
   42
                 (c)      The purchase price to be paid by the Company pursuant
to this Section 8.2, if such tender offer is consummated, shall be the purchase
price that the Purchaser would have received if it had tendered the Voting
Stock purchased by the Company and all such Voting Stock had been purchased in
such tender offer, including any increases in the price paid by the tender
offeror after exercise by the Company of its right of first refusal hereunder.
If the purchase price paid by the tender offeror includes any property other
than cash, the value of such property shall be jointly determined by a
nationally recognized investment banking firm selected by the Company and the
Purchaser or, in the event such firms are unable to agree, a third nationally
recognized investment banking firm to be selected by such two firms.  The
Company and the Purchaser shall use their best efforts to cause any
determination of the value of any such property included in the purchase price
to be made within two (2) business days after consummation of the tender offer.
If the firms selected by the Company and the Purchaser are unable to agree upon
the value of any such securities within such 2-day period, the firms shall
promptly select a third firm whose determination shall be made promptly and
shall be conclusive.  The Company and the Purchaser shall each bear the cost of
its own investment banking firm and shall share equally the costs of any third
firm selected hereunder.

                 (d)      If the Company does not exercise such right by giving
such notice or fails to complete the purchase, then the





                                      -38-
   43
Purchaser shall be free to accept the tender offer with respect to which the
Tender Notice was given.

         8.3     Assignment of Rights.  In the event that the Company elects to
exercise a right of first refusal under this Section 8, the Company may specify
prior to closing such purchase another person as its designee to purchase all
or part of the Voting Stock to which such notice relates.  Any such designee
shall be subject to the approval of the Purchaser proposing to sell or tender,
as the case may be, any of its Shares, which approval shall not unreasonably be
withheld.  If the Company shall designate another person as the purchaser
pursuant to this Section 8, the giving of notice of acceptance of the right of
first refusal by the Company shall constitute a legally binding obligation of
the Company to complete such purchase if such person shall fail to do so.


                                   SECTION 9
