Item 2. Acquisition or Disposition of Assets

      On December 24, 1999, pursuant to an Agreement and Plan of Merger dated as
of December 14, 1999 (the "Merger Agreement"), by and among Network Equipment
Technologies, Inc., a Delaware corporation ("N.E.T."), IPNow, Inc., a California
corporation and wholly-owned subsidiary of N.E.T. ("Sub"), and FlowWise
Networks, Inc., a California corporation ("FlowWise"), Sub was merged with and
into FlowWise, with FlowWise being the surviving corporation and thereafter a
wholly-owned subsidiary of N.E.T. (the "Merger").

      FlowWise, formed in 1996 and based in San Jose, California, develops
high-performance router acceleration products that are self-configuring and
enable enterprises to enhance the performance of their networks.

      The aggregate purchase price for the outstanding shares of FlowWise
capital stock including expenses of approximately $600,000 was $16,000,000. The
source of the funds for the acquisition was N.E.T.'s working capital.

      Pursuant to the Merger Agreement, at the effective time of the Merger, (i)
each outstanding share of Common Stock of FlowWise ("FlowWise Common Stock")
(except for Dissenting Shares (as defined in the Merger Agreement), if any) was
converted into the right to receive $0.079936 in cash ($0.006395 of which is
conditional and has been withheld to secure certain indemnification obligations
(as described below)); and (ii) each outstanding share of Series A Preferred
Stock of FlowWise ("Series A Preferred Stock"), Series B Preferred Stock of
FlowWise ("Series B Preferred Stock,), and Series C Preferred Stock of FlowWise
("Series C Preferred Stock" and, with the Series A Preferred Stock and Series B
Preferred Stock, the "FlowWise Preferred Stock") (except for Dissenting Shares,
if any) was converted into the right to receive $1.82955 in cash ($0.14636 of
which is conditional and has been withheld to secure certain indemnification
obligations (as described below)). Such consideration was determined in
arm's-length negotiations between N.E.T. and FlowWise. In addition, at the
effective time of the Merger, each option to purchase shares of FlowWise Common
Stock was terminated. N.E.T. also agreed, pursuant to the terms of the Merger
Agreement, to pay certain obligations of FlowWise.

      Pursuant to the Merger Agreement, the shareholders of FlowWise have agreed
to indemnify and hold N.E.T. and its affiliates harmless from losses that N.E.T.
or its affiliates may suffer as a result of (i) any breach of, or any inaccuracy
in, its representations and warranties of FlowWise made pursuant to the Merger
Agreement (and any ancillary documents delivered in connection therewith), (ii)
any breach of any covenant or obligation of FlowWise required by the Merger
Agreement (or by any ancillary documents delivered in connection therewith), or
(iii) any legal proceeding relating to any inaccuracy, breach or expense of the
type referred to above. An aggregate of $1,280,000 of the consideration payable
to the shareholders of FlowWise (as described above) will be retained by an
escrow agent to secure these indemnification obligations.

      The Merger will be accounted for under the purchase method of accounting.

      WHEREAS, FlowWise, NET and Sub believe it is in the best interests of each
company, the stockholders of NET and the shareholders of FlowWise that NET

      WHEREAS, pursuant to the Merger, among other things, each issued and

                                      -7-
<PAGE>

                  (i) an amount in cash per share equal to the amount obtained
by dividing Nine Hundred Sixteen Thousand Eight Hundred Eighty Three Dollars and
Twelve Cents ($916,883.12) by the number of shares of FlowWise Common Stock that
are issued and outstanding immediately prior to the Effective Time (together
with the amounts payable pursuant to Sections 2.1(b)(i), the "Initial Merger
Consideration"); and

                  (ii) a conditional amount of cash per share equal to the
amount obtained by dividing Eighty Three Thousand One Hundred Sixteen Dollars
and Eighty Eight Cents ($83,116.88) by the number of shares of FlowWise Common
Stock that is issued and outstanding immediately prior to the Effective Time
(together with the amounts payable pursuant to Section 2.1(b)(ii), the "Holdback
Amount").

            (b) As of the Effective Time, each share of FlowWise Preferred Stock
that is issued and outstanding immediately prior to the Effective Time of the
Merger (except for Dissenting Shares, if any) shall, by virtue of the Merger and

            (c) The Initial Merger Consideration and the Holdback Amount (as

exist, and each holder of a certificate presenting any such shares shall cease
to have any rights with respect thereto, except the right to receive the Merger
Consideration represented by such certificate upon the surrender of such
certificate in accordance with Section 2.2, without interest. "Dissenting Share"
means any FlowWise Share in respect of which any FlowWise Shareholder has

not been exercised, shall be cancelled and Plan shall be terminated.

<PAGE>

Merger and without any action on the part of NET, Sub or FlowWise, be converted
into one share of Common Stock of the Surviving Corporation.

      2.2 Exchange of Certificates.

            (a) Exchange Agent. NET shall deposit with such bank or trust
company as may be designated by NET, subject to the reasonable approval of the
Shareholders' Representative (the "Exchange Agent"), appointed pursuant to the
terms of the Exchange Agreement substantially in the form attached hereto as
Exhibit D (the "Exchange Agreement"), for the benefit of the holders of shares
of FlowWise Capital Stock, for exchange in accordance with this Article II,
through the Exchange Agent, as of the Effective Time, cash (i) in the amount
sufficient to pay the Initial Merger Consideration, and (ii) the Holdback Amount
(collectively, such cash consideration, the "Exchange Fund"). The Exchange Fund
shall be invested by the Exchange Agent in money market funds with no less than
a AAA rating.

            (b) Exchange Procedures. As soon as practicable after the Effective
Time, but in any event no later than ten (10) business days after the Effective
Time, the Exchange Agent shall, in accordance with the terms of the Exchange
Agreement, mail to each holder of record of a Certificate or Certificates
immediately prior to the Effective Time, whose shares were converted into the
right to receive the Merger Consideration pursuant to Section 2.1, (i) a letter
of transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and shall be in such form and have such other
provisions as NET may reasonably specify), and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for the Merger
Consideration (collectively, the "Letter of Transmittal"). Upon the later of the
Effective Time or the surrender of a Certificate for cancellation to the
Exchange Agent or to such other agent or agents as may be appointed by NET,
together with such Letter of Transmittal, duly executed, and such other
documents as may be reasonably required by the Exchange Agent, the holder of
such Certificate shall be entitled to receive in exchange therefor a check in
the amount equal to the cash that such holder has the right to receive pursuant
to the provisions of this Article II in respect of the Initial Merger
Consideration payable to such holder (less the amount of any withholding taxes,
if any, required under applicable law), and the Certificate so surrendered shall
forthwith be canceled. At the expiration of the Indemnification Period, the
Holdback Amount as such amount may be adjusted in accordance with Section 2.4
below, plus interest thereon as determined in the manner set forth below, in the
Exchange Fund, shall be distributed by the Exchange Agent in accordance with the
terms of the Exchange Agreement, with accrued interest to be distributed
proportionately as the Holdback Amount is distributed. Any accrued interest on
the Holdback Amount shall be paid at the expiration of the Indemnification
Period (as provided for by the previous sentence. Until surrendered as
contemplated by this Section 2.2(b), each Certificate (other than those
representing Dissenting Shares) shall be deemed at any time after the Effective
Time to represent only the right to receive upon such surrender the Merger
Consideration which the holder thereof has the right to receive in respect of
such Certificate pursuant to this Article II. Except as set forth with respect
to the Holdback Amount, no interest will be paid or will accrue on any cash
payable to holders of Certificates pursuant to this Article II.


                                      -9-
<PAGE>

            (c) Termination of Exchange Fund. The Exchange Fund shall terminate
in accordance with the terms of the Exchange Agreement.

            (d) No Liability. None of NET, Sub, and the Exchange Agent shall be
liable to any person in respect of any shares of FlowWise Capital Stock (or any
dividends or distributions with respect thereto or with respect to any shares of
FlowWise Capital Stock theretofore represented by any Certificate) or any cash
from the Exchange Fund delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law. If any Certificate shall not have
been surrendered prior to the date on which any Merger Consideration or other
dividends or distributions payable to the holder of such Certificate pursuant to
this Article II would otherwise escheat to or become the property of any
Governmental Body, any such Merger Consideration or cash or other dividends or
distributions shall, to the extent permitted by applicable law, become the
property of the Surviving Corporation, free and clear of all claims or interests
of any person previously entitled thereto.

      2.3 Dissenting Shares. Any Dissenting Shares shall be converted into the
right to receive such consideration as may be determined to be due with respect
to such Dissenting Shares pursuant to the California Code; provided, however,
that if the status of any such shares as Dissenting Shares shall not be
perfected, or if any such shares shall lose their status as Dissenting Shares,
then, as of the later of the Effective Date or the time of the failure to
perfect such status, such shares shall automatically be converted into and shall
represent only the right to receive (upon the surrender of the Certificate or
Certificates representing such shares) cash in accordance with Section 2.1.
FlowWise shall give NET prompt notice of any demand received by FlowWise for
purchase of FlowWise Capital Stock, and NET shall have the right to participate
in all negotiations and proceedings with respect to such demand. FlowWise agrees
that, except with the prior written consent of NET or as required under Chapter
13 of the California Code, it will not voluntarily make any payment with respect
to, or settle or offer to settle, any such demand for purchase. Each holder of
Dissenting Shares ("Dissenting Shareholder") who, pursuant to the provisions of
the California Code, becomes entitled to payment of the value of shares of
FlowWise Capital Stock shall receive payment therefor from the Surviving
Corporation (but only after the value therefor shall have been agreed upon or
finally determined pursuant to such provisions).

      2.4 Post-Closing Adjustment to Holdback Amount. The Holdback Amount may be
reduced from time to time in accordance with the provisions of Article XI of
this Agreement. Any reduction to the Holdback Amount pursuant to Article XI
shall be made by the Exchange Agent paying NET the amount to which the FlowWise
Shareholders are no longer entitled. The balance of the Holdback Amount shall
paid upon the expiration of the Indemnification Period as provided in Section
2.2

      3.4 Financial Statements. FlowWise has delivered to NET the following
financial statements (collectively the "FlowWise Financial Statements"): (a)
audited balance sheets and statements of income, changes in shareholders'

equity, and cash flow (the "Most Recent Financial Statements") as of and for the

the periods covered thereby, present fairly the financial condition of FlowWise
as of such dates and the results of operations of FlowWise for such periods, are
correct and complete, and are consistent with the books and records of FlowWise
(which books and records are correct and complete); provided, however, that the
Most Recent Financial Statements are subject to normal year-end adjustments
(which will not be material individually or in the aggregate) and lack footnotes
and other presentation items. FlowWise has no Liabilities (and there is no Basis
known to FlowWise for any present or future action, suit, proceeding, hearing,

reports required to be filed by it, including all federal, foreign, state and
local tax returns and estimates which are due in the period from the date hereof

are adequate with respect to the periods covered therein, and there are no tax
liens on any property or assets of FlowWise (other than liens for taxes not yet
due and payable). There have been no audits or examinations of any tax returns
or reports by any applicable Governmental Body. No state of facts exists or has
existed which would constitute grounds for the assessment of any penalty or any
further tax Liability in a material amount, either individually or in the
aggregate, beyond that shown on the respective tax reports, returns or estimates
or accrued for or reserved on the FlowWise Financial Statements with respect to
the periods covered by such reports, returns, estimates or statements or with
respect to the period from the date hereof through and including the Effective
Date. There are no outstanding agreements or waivers extending the statutory

occurred by January 31, 2000, unless otherwise mutually agreed in writing by the

occur is the result of the failure on the part of such party to perform any of

this Article X shall be without further obligation or Liability upon any party
in favor of any other party hereto; provided, however, that if such termination
by one party shall result from the willful failure of the other party to carry

construed as limiting or denying any legal or equitable right or remedy of said
party, and said party shall be entitled to recover its costs and expenses which
are incurred in pursuing its rights and remedies (including reasonable
attorneys' fees).

      10.3 Certain Effects of Termination. In the event of the termination of
this Agreement by either FlowWise or NET as provided in Section 10.1 hereof:

such other party) in connection with the transactions contemplated hereby,
whether so obtained before or after the execution of this Agreement, and any
copies thereof which may have been made, and will cause its representatives and
others to whom such documents were furnished promptly to return such documents

the representations and warranties set forth in Article III hereof and the
representations and warranties set forth in any certificate delivered by
FlowWise in connection with this Agreement) shall survive the Closing and shall
remain in full force and effect and shall survive until the expiration of the

representations and warranties made by NET and Sub shall survive the Closing,
shall remain in full force and effect and shall survive until the expiration of
the Indemnification Period, and the FlowWise Shareholders shall be expressly
permitted to rely on such representations and warranties as third party
beneficiaries; provided, however, that the termination hereunder of the
representations and warranties made by NET and Sub shall not terminate or limit
in any manner whatsoever any rights which FlowWise or the FlowWise Shareholders
have or may have for knowing and intentional misrepresentation.

            (b) As used in this Agreement, Indemnification Period shall mean a
period of one (1) year from the Closing Date, subject to Section 11.3(e) hereof;
provided, however, that the expiration of any Indemnification Period shall not
limit the rights any Indemnitees with respect to indemnification under this
Article XI in respect of any claim commenced within the Indemnification Period.

            (c) The representations, warranties, covenants and obligations of
FlowWise, and the rights and remedies that may be exercised by the Indemnitees,
shall not be limited or otherwise affected by or as a result of any information
furnished to, or any investigation made by or knowledge of, any of the
Indemnitees or any of their representatives.

      11.2 Indemnification by FlowWise Shareholders.

            (a) From and after the Closing Date (but subject to Section
11.1(a)), the Shareholders of FlowWise shall hold harmless and indemnify each of
the Indemnitees from and against, and shall compensate and reimburse each of the
Indemnitees for, any Damages which are suffered or incurred by any of the
Indemnitees or to which any of the Indemnitees may otherwise


                                      -40-
<PAGE>

become subject (regardless of whether or not such Damages relate to any
third-party claim) and which arise from or as a result of:

                  (i) any inaccuracy in or breach of any representation or
warranty set forth in Article III hereunder or in any certificate delivered by
FlowWise in connection with this Agreement;

                  (ii) any breach of any covenant or obligation of FlowWise
hereunder,

                  (iii) any Legal Proceeding relating to any inaccuracy, breach
or expense of the type referred to in clause (i) or (ii) above (including any
Legal Proceeding commenced by any Indemnitee for the purpose of enforcing any of
its rights under this Article XI if such Indemnitee is the prevailing party in
any such Legal Proceeding).

            (b) If the Surviving Corporation suffers, incurs or otherwise
becomes subject to any Damages as a result of or in connection with any
inaccuracy in or breach of any representation, warranty, covenant or obligation
of FlowWise hereunder, then (without limiting any of the rights of the Surviving
Corporation as an Indemnitee) NET shall also be deemed, by virtue of its
ownership of the stock of the Surviving Corporation, to have incurred Damages as
a result of and in connection with such inaccuracy or breach.

      11.3 Floor; Ceiling; Exclusivity; Claims Process.

            (a) The FlowWise Shareholders shall not be required to make any
indemnification payment pursuant to Section 11.2(a) until such time as and only
to the extent that the total amount of all Damages (including the Damages
arising from any inaccuracy or breach of any representation or warranty and all
other Damages arising from any other inaccuracies in or breaches of any
representations or warranties) that have been suffered or incurred by any one or
more of the Indemnitees, or to which any one or more of the Indemnitees has or
have otherwise become subject, exceeds Twenty-Five Thousand Dollars ($25,000) in
the aggregate.

            (b) Except with respect to claims based on knowing and intentional
misrepresentations of representations and warranties, NET and Sub agree on
behalf of the Indemnitees that, after the Closing, the sole recourse of the
Indemnitees with respect to Damages shall be against the Holdback Amount in the
manner set forth in Section 2.4 of this Agreement.

            (c) In the event that an Indemnitee shall have incurred any Damages
for which Indemnitee wishes to seek adjustment to the Holdback Amount pursuant
to Section 11.1, Indemnitee shall deliver to the Shareholder Representative and
the Exchange Agent an Officer's Certificate: (i) stating that Indemnitee has
paid Damages, (ii) specifying in reasonable detail the individual items of
Damages included in the amount so stated, the date each such item was paid, and
the nature of the misrepresentation, breach of warranty or covenant or other
adjustment to the Holdback Amount to which such item is related, and (iii)
indicating that Indemnitee is seeking adjustment to the Holdback Amount under
this Article XI. Nothing in this Section 11.3(c) shall limit the right of an
Indemnitee to seek an adjustment to the Holdback Amount under this Article


                                      -41-
<PAGE>

XI in accordance with Section 11.3(e) with respect to Damages that such
Indemnitee reasonably anticipates that it will have to pay or accrue, subject to
the other provisions of this Section 11.3.

            (d) In the event that an Indemnitee has elected to pursue adjustment
to the Holdback Amount under this Article XI, the amount stated in the Officer's
Certificate shall be delivered to the Indemnitee by the Exchange Agent, unless
the Shareholder Representative contests such claim in writing within thirty (30)
days after such election. In such event, the parties will follow the procedures
set forth in Section 13.2 below (in which case the payment of the amount of the
Holdback Amount shall be made as determined pursuant to Section 13.2 with any
amounts to be paid to an Indemnitee to be paid by the Exchange Agent following
such determination and any amounts to be paid to the FlowWise Shareholders to be
paid upon the later of the expiration of the Indemnification Period or ten (10)
days after a final determination of a claim).

            (e) Notwithstanding anything to the contrary herein, no later than
the date of the expiration of the Indemnification Period, in the event that an
Indemnitee reasonably anticipates that it will have to pay or accrue Damages
relating to (i) claims for which such Indemnitee has not provided notice
pursuant to subsection (c) hereof that such Indemnitee reasonably believes are
indemnifiable under this Article XI, or (ii) claims for which such Indemnitee
has provided notice pursuant to subsection (c) of this Section 11.3 that have
not been finally resolved in accordance with this Article XI, the Indemnitee
shall deliver to the Shareholder Representative and the Exchange Agent an
Officer's Certificate setting forth the information identified in clauses (i),
(ii) and (iii) of subsection (c) of this Section 11.3 (including, without
limitation, information relating to any anticipated claims and the Basis for
such anticipated Liability). The amount stated in the Officer's Certificate
shall be delivered to the Indemnitee unless the Shareholder Representative
contest such claim in writing within ten (10) days after receipt of such notice.
In such event, as soon as practicable but in no event later than twenty (20)
days after the receipt of the notice of objection from the Shareholder
Representative, the parties shall submit the claim to the Neutral Third Party
(as defined below) for a determination to be made within sixty (60) days after
submission whether a reasonable likelihood exists that any Damages (including
attorney's fees) will be incurred or accrued by the Indemnitee for such claims.
In the event that the Neutral Third Party determines that a reasonable
likelihood does not exist, then the Holdback Amount in dispute as a result of
that claim shall be distributed to the Former Holders in accordance with the
terms of the Exchange Agreement. In the event that the Neutral Third Party
determines that a reasonable likelihood does exist that any Damages (including
attorney's fees) will be incurred or accrued by the Indemnitee for such claim,
then such amount stated in the Officer's Certificate shall remain in escrow,
subject to the Exchange Agreement, until such time as the amount of such Damages
is paid or properly accrued by the Indemnitee. At such time, the parties shall
follow the procedure set forth in subsections (c) and (d) of this Section 11.3.
The costs and expenses of the Neutral Third Party as well as any additional
amounts due under the Exchange Agreement in connection with the procedure
described herein shall be paid from the Holdback Amount.

For purposes of this Section 11.3, the Neutral Third Party shall mean a third
party selected by the parties in the following manner: within five (5) days
following receipt of the Shareholder Representative's notice of objection, NET,
on the one hand, and the Shareholder Representative, on the other hand, shall
each propose an unaffiliated third party who is qualified and experienced


                                      -42-
<PAGE>

for such determination (the "NET Nominee" and "FlowWise Nominee," respectively).
Within five (5) days thereafter, the parties may mutually agree that either the
NET Nominee or the FlowWise Nominee shall act as the Neutral Third Party. In the
event that both (i) the NET Nominee is not reasonably acceptable to FlowWise,
and (ii) the FlowWise Nominee is not reasonably acceptable to NET, then within
ten (10) days after the initial proposals, the NET Nominee and the FlowWise
Nominee shall select a third party unaffiliated with both NET and FlowWise and
such individual shall act as the Neutral Third Party. In the event that neither
party proposes an unaffiliated third party within the five-day initial proposal
period, the first party to propose an unaffiliated third party in writing
thereafter shall have the right to appoint such third party as the Neutral Third
Party.

      11.4 No Contribution. The Shareholders acknowledge and agree that they
shall not have and shall not exercise or assert (or attempt to exercise or
assert), any right of contribution, right of indemnity or other right or remedy
against the Surviving Corporation in connection with any indemnification
obligation or any other Liability to which they may become subject under or in
connection with this Agreement or any certificate delivered by FlowWise in
connection with this Agreement.

      11.5 Defense of Third Party Claims. In the event of the assertion or
commencement by any Person of any claim or Legal Proceeding (whether against the
Surviving Corporation, against NET or against any other Person) with respect to
which the Shareholders may become obligated to hold harmless, indemnify,
compensate or reimburse any Indemnitee pursuant to this Article XI, the
procedure set forth in Sections 11.6 and 11.7 below shall be followed.

      11.6 Notice. NET shall give prompt written notice to the Shareholder
Representative pursuant to Section 11.9 of the commencement of any such Legal
Proceeding against NET or the Surviving Corporation for which indemnity may be
sought under Article XI together with a description of such Legal Proceeding and
the specific bases upon which such indemnity may be sought consistent with the
provisions of this Agreement; provided, however, that any failure on the part of
NET to so notify the Shareholder Representative shall not limit any of the
obligations of the Shareholders under this Article XI (except to the extent such
failure materially prejudices the defense of such Legal Proceeding). The
Indemnification Period shall be tolled solely with respect to a particular claim
for the period beginning on the date the Shareholder Representative receives
written notice of that claim until the final resolution of such claim so long as
such claim is made within the Indemnification Period.

      11.7 Defense of Claim. The Indemnitee shall have the right to be
represented by counsel of its choice and to defend or otherwise control the
handling of any third party claim or Legal Proceeding for which indemnity is
sought. Notwithstanding the foregoing, the Shareholder Representative may elect
on behalf of the Shareholders (by written notice by the Shareholder
Representative to NET within thirty (30) days after receipt of written notice
under Section 11.6) to assume the defense of or otherwise control the handling
of any such third party claim or Legal Proceeding (other than for matters
relating to the intellectual property rights of NET (including FlowWise), or
claims by customers of NET) for which indemnity is sought so long as, and only
in the event that, the maximum amount reasonably expected to be payable with
respect to any such


                                      -43-
<PAGE>

Legal Proceeding by FlowWise or NET would not exceed the Holdback Amount in
NET's reasonable determination, subject to the further limitations provided
herein.

            (a) If the Shareholder Representative so elects to assume the
defense of any such claim or Legal Proceeding:

                  (i) the Shareholders shall proceed to defend such claim or
Legal Proceeding in a diligent manner with counsel reasonably satisfactory to
the Indemnitee;

                  (ii) the Indemnitee shall make available to the Shareholder
Representative any documents and materials in the possession of the Indemnitee
that may be necessary to the defense of such claim or Legal Proceeding;

                  (iii) the Shareholder Representative shall keep the Indemnitee
informed of all material developments and events relating to such claim or Legal
Proceeding;

                  (iv) the Indemnitee shall have the right to participate in the
defense of such claim or Legal Proceeding at the Indemnitee's expense (except
that the FlowWise Shareholders shall pay the fees and expenses of such counsel
out of the Holdback Amount to the extent that the Indemnitee reasonably
concludes that there is a conflict of interest between the Indemnitee and the
FlowWise Shareholders); and

                  (v) the Shareholder Representative shall have the right to
settle, adjust or compromise such claim or Legal Proceeding only with the
consent of NET; provided, however, that NET shall not unreasonably withhold such
consent.

            (b) If the Shareholder Representative does not (or cannot) elect to
assume the defense of any such third party claim or Legal Proceeding, the
Indemnitee may proceed with the defense of such claim or Legal Proceeding on its
own. If the Indemnitee so proceeds with the defense of any such claim or Legal
Proceeding on its own:

                  (i) all expenses relating to the defense of such claim or
Legal Proceeding (whether or not incurred by the Indemnitee) shall be borne and
paid exclusively by the Shareholders out of the Holdback Amount, provided,
however, that the Shareholders shall not be liable for the costs of more than
one counsel on behalf of the Indemnities collectively;

                  (ii) the Shareholders shall make available to the Indemnitee
any documents and materials in the possession or control of the Shareholders
that may be necessary to the defense of such claim or Legal Proceeding except
for documents or materials which are sealed by a court order or are subject to a
nondisclosure agreement prohibiting disclosure by the Shareholders;

                  (iii) the Indemnitee shall keep the Shareholder Representative
informed of all material developments and events relating to such claim or Legal
Proceeding; and


                                      -44-
<PAGE>

                  (iv) the Indemnitee shall have the right to settle, adjust or
compromise such claim or Legal Proceeding with the consent of the Shareholder
Representative; provided, however, that the Shareholder Representative shall not
unreasonably withhold such consent.

      11.8 Exercise of Remedies by Indemnitees Other than NET. No Indemnitee
(other than NET or any successor thereto or assignee thereof) shall be permitted
to assert any indemnification claim or exercise any other remedy under this
Agreement unless NET (or any successor thereto or assign thereof) shall have
consented to the assertion of such indemnification claim or the exercise of such
other remedy.

      11.9 Shareholder Representative; Approval of Shareholders.

            (a) Kenneth P. Lawler shall be constituted and appointed as agent
("Shareholder Representative") for and on behalf of the Shareholders to give and
receive notices and communications, to authorize distribution to NET of the
Holdback Amount in satisfaction of claims by NET, to object to such distribution
to NET of the Holdback Amount, to agree to, negotiate, enter into settlements
and compromises of, and demand arbitration and comply with orders of courts and
awards of arbitrators with respect to such claims, and to take all actions
necessary or appropriate in the judgment of the Shareholder Representative for
the accomplishment of the foregoing. Such agency may be changed by the
Shareholders, with the vote of the Shareholders to be determined by their pro
rata interests in the Holdback Amount from time to time upon not less than ten
(10) business days' prior written notice to NET. No bond shall be required of
the Shareholder Representative, and the Shareholder Representative shall receive
no compensation for his/her services. Notices or communications to or from the
Shareholder Representative shall constitute notice to or from each of the
Shareholders.

            (b) The Shareholder Representative shall not be liable for any act
done or omitted hereunder as Shareholder Representative while acting in good
faith and not in a manner constituting gross negligence, and any act done or
omitted pursuant to the advice of counsel shall be conclusive evidence of such
good faith. The Shareholders shall severally indemnify the Shareholder
Representative and hold him/her harmless against any loss, liability or expense
incurred without gross negligence or bad faith on the part of the Shareholder
Representative and arising out of or in connection with the acceptance or
administration of his/her duties hereunder. Subject to the prior right of NET to
make claims for damages, the Shareholder Representative, with the consent of
Shareholders entitled to a majority in interest in the Holdback Amount, may
recover from the Holdback Amount prior to any payment to the Shareholders
reasonable costs and expenses incurred by the Shareholder Representative in
connection with acting as same.

            (c) The approval by the Shareholders of the Merger shall be deemed
to be approval of the terms of the provisions of this Article XI, including the
appointment of the Shareholder Representative.

            (d) A decision, act, consent or instruction of the Shareholder
Representative shall constitute a decision of all FlowWise Shareholders and
shall be final, binding and conclusive upon each such FlowWise Shareholder, and
NET may rely upon any such decision, act, consent or instruction of the
Shareholder Representative as being the decision, act, consent or instruction


                                      -45-
<PAGE>

of each every such FlowWise Shareholder. NET is hereby relieved from any
Liability to any person for any acts done by it in accordance with such
decision, act, consent or instruction of the Shareholder Representative.

                                  ARTICLE XII
                              EMPLOYEE ARRANGEMENTS

      12.1 Transaction Bonus Agreements. NET and FlowWise acknowledge that each
of the employees of FlowWise listed on Exhibit F hereto (each a "Key Employee"
and collectively the "Key Employees") have executed and delivered a Transaction
Bonus Agreement, as amended ("Transaction Bonus Agreement"), with NET which
agreement will be effective at the Effective Time.

      12.2 Bonus Pool. In connection with the Merger, NET agrees to establish a
bonus pool for certain employees of FlowWise following the Effective Date (the
"Bonus Pool"). The Bonus Pool shall be established in accordance with and
subject to the terms of the Transaction Bonus Agreements. NET will deposit the
Bonus Pool with the Exchange Agent for distribution in accordance with the terms
of an agreement reasonably satisfactory to the Shareholder Representative.

      12.3 Employee Benefit Plans. NET and FlowWise hereby agree that to the
extent the existing Employee Benefit Plans provided by FlowWise to its employees
are terminated or merged with existing NET Employee Benefit Plans after the
Closing Date, such employees who are hired by NET shall be entitled to
participate in all benefit plans and arrangements which are available and
subsequently become available to NET's employees of similar position on the same
basis as NET's employees. For purposes of eligibility to participate and vesting
requirements in the NET Employee Benefit Plans for which any former FlowWise
employee may be eligible upon hire by NET, to the extent permissible under the
relevant plans, service by a former FlowWise employee with FlowWise shall be
deemed to have been service with NET.

      12.4 Assumption of Indemnity Obligations.

            (a) Articles of Incorporation and Bylaws. The Surviving Corporation
agrees that the obligations set forth in the Amended and Restated Articles of
Incorporation and Bylaws of FlowWise, as in effect immediately prior to the
Effective Time, to indemnify its officers and directors shall survive the
Merger, and any rights of the directors and officers to such indemnification
thereunder shall not be adversely affected by any amendment, repeal or other
modification thereto after the Effective Time.

            (b) Exclusion. Notwithstanding the foregoing, nothing in this
Section 12.4 is intended to release any director or officer of FlowWise, who is
also a shareholder of FlowWise, from its indemnification obligations under
Section 11 hereof.

                                  ARTICLE XIII
                                  MISCELLANEOUS

      13.1 Governing Laws. It is the intention of the parties hereto that the
internal laws of the State of California (irrespective of its choice of law
principles) shall govern the validity of this Agreement, the construction of its
terms, and the interpretation and enforcement of the rights and duties of the
parties hereto.

      13.2 Amicable Resolution. NET and FlowWise mutually desire that friendly
collaboration will develop between themselves. Accordingly, they shall try to
resolve in a friendly manner all disagreements and misunderstandings connected
with their respective rights and obligations under this Agreement, including any
amendments hereof.


      Excluding Intellectual Property disputes which must be brought before a
court of competent jurisdiction, to the extent that any misunderstanding or
dispute which arises after the Effective Date cannot be resolved agreeably in a
friendly manner, the dispute will be mediated by a mutually-acceptable mediator
to be chosen by NET and the Shareholder Representative within forty-five (45)
days after written notice by one of the parties demanding mediation. Neither
party may unreasonably withhold consent to the selection of a mediator, however,
by mutual agreement NET and the Shareholder Representative may postpone
mediation until each has completed specified but limited discovery with respect
to a dispute. The parties may also agree to attempt some other form of
alternative dispute resolution ("ADR") in lieu of mediation, including by way of
example and without limitation neutral fact-finding or a mini-trial.

      Any dispute that the parties cannot resolve through negotiation, mediation
or other form of ADR within six months of the date of the initial demand for it
by one of the parties may then be submitted to the courts for resolution. The
use of any ADR procedures will not be construed under the doctrines of laches,
waiver or estoppel to affect adversely the rights of either party. Nothing in
this Section 13.2 will prevent either party from resorting to judicial
proceedings if (i) good faith efforts to resolve the dispute under these
procedures have been unsuccessful or (ii) interim relief from a court is
necessary to prevent serious and irreparable injury to one party or to others.
13.3 Limitation on Liability. NOTWITHSTANDING ANY OTHER PROVISION OF THIS
AGREEMENT, IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR SPECIAL, INCIDENTAL,
INDIRECT, COLLATERAL, CONSEQUENTIAL OR PUNITIVE DAMAGES IN CONNECTION WITH ANY
CLAIMS, LOSSES, DAMAGES, OR INJURIES ARISING OUT OF THE CONDUCT OF THE PARTIES
PURSUANT TO THIS AGREEMENT.

      13.4 Binding Upon Successors and Assigns. Subject to, and unless otherwise
provided in, this Agreement, each and all of the covenants, terms, provisions,
and agreements contained herein shall be binding upon, and inure to the benefit
of, the permitted successors, executors, heirs, representatives, administrators
and assigns of the parties hereto.

      13.5 Severability. If any provision of this Agreement, or the application
thereof, shall for any reason and to any extent be invalid or unenforceable, the
remainder of this Agreement and


                                      -47-
<PAGE>

application of such provision to other persons or circumstances shall be
interpreted so as best to effect reasonably the intent of the parties hereto.
The parties further agree to replace such void or unenforceable provision of
this Agreement with a valid and enforceable provision which will achieve, to the
extent possible, the economic, business and other purposes of the void or
unenforceable provision.

      13.6 Entire Agreement; Assignment. This Agreement (with all of the
exhibits, appendices and schedules appended hereto and thereto), the FlowWise
Disclosure Statement, and the documents and instruments and other agreements
among the parties hereto referenced herein: (i) constitute the entire agreement
among the parties with respect to the subject matter hereof and supersede all
prior agreements and understandings both written and oral, among the parties
with respect to the subject matter hereof; (ii) are not intended to confer upon
any other person (including, without limitation, any employee of FlowWise or any
such employee's spouse, dependents or beneficiaries) except the Shareholder
Representative any rights or remedies hereunder; and (iii) shall not be assigned
by FlowWise whether by operation of law or otherwise without the prior written
consent of NET.

      13.7 Counterparts. This Agreement may be executed in any number of
counterparts, including counterparts transmitted by telecopier or telefax, each
of which shall be an original as against any party whose signature appears
thereon and all of which together shall constitute one and the same instrument.
This Agreement shall become binding when one or more counterparts hereof,
individually or taken together, shall bear the signatures of all of the parties
reflected hereon as signatories.

      13.8 Expenses. Whether or not the transactions herein contemplated shall
be consummated, NET will pay the fees, expenses and disbursements of NET and Sub
and its agents, representatives, accountants and counsel incurred in connection
with the subject matter of this Agreement and any amendments thereto. Whether or
not the transactions herein contemplated shall be consummated, FlowWise will pay
the fees, expenses and disbursements of FlowWise and its agents,
representatives, accountants and counsel incurred in connection with the subject
matter of this Agreement and any amendments thereto and all other costs and
expenses incurred in the performance and compliance with all conditions to be
performed by FlowWise under this Agreement. Notwithstanding the foregoing,
neither NET nor FlowWise shall be liable for any fees or expenses payable to any
broker or finder contemplated by Section 3.25 of this Agreement, except that NET
shall pay (a) the fee of Five Hundred Thousand Dollars ($500,000 to Credit
Suisse First Boston Corporation, an investment banking firm retained by FlowWise
as identified in Part 3.25 of the FlowWise Disclosure Statement, and (b) the
reasonable expenses and fees of Venture Law Group, A Professional Corporation,
in connection with its representation of FlowWise in connection herewith, if the
Merger is consummated.

      13.9 Amendment and Waivers. Any term or provision of this Agreement may be
amended, and the observance of any term of this Agreement may be waived (either
generally or in a particular instance and either retroactively or prospectively)
only by a writing signed by the party to be bound thereby. The waiver by a party
of any breach hereof for default in payment of any amount due hereunder or
default in the performance hereof shall not be deemed to constitute a waiver of
any other default or any succeeding breach or default.


                                      -48-
<PAGE>

      13.10 No Waiver. The failure of any party to enforce any of the provisions
hereof shall not be construed to be a waiver of the right of such party
thereafter to enforce such provisions.

      13.11 Notices. Any notice provided for or permitted under this Agreement
will be treated as having been given when (a) delivered personally, (b) sent by
confirmed telecopy, (c) sent by commercial overnight courier with written
verification of receipt, or (d) mailed postage prepaid by certified or
registered mail, return receipt requested, to the party to be notified, at the

<PAGE>

                                    AGREEMENT

      NOW, THEREFORE, in consideration of the entering into the Merger
Agreement, and for other good and valuable consideration, the receipt and
adequacy of which is hereby acknowledged, the parties hereby agree as follows:

      8. Exchange Services.

            8.1 Merger Consideration Schedule. On or prior to the Closing Date,
FlowWise will furnish the Exchange Agent with a copy of a schedule (the "Merger
Consideration Schedule"), substantially in the form attached hereto as Exhibit
A, showing (a) the name and address of each of the Former Holders (other than
holders of Dissenting Shares, if any), (b) the number of shares of FlowWise
Capital Stock held by each Former Holder (other than holders of Dissenting
Shares, if any) as of the Effective Time, (c) the amount of the Initial Merger
Consideration payable to each Former Holder (other than holders of Dissenting
Shares, if any) as the Effective Time, and (d) the amount of the Holdback Amount
payable to each Former Holder (other than holders of Dissenting Shares, if any)
upon the one (1) year anniversary of the Closing Date (the period from the
Closing Date to such anniversary, the "Indemnification Period") (assuming no
adjustment thereto), subject to Section 2.3(c) hereof.

            8.2 Initial Deposits by NET. On the Closing Date, NET shall deposit
with the Exchange Agent (a) the Initial Merger Consideration, and (b) the
Holdback Amount. The account into which each of the items referred to in this
Section 1.2 is to be deposited shall be referred to hereinafter as the "Exchange
Fund."

            8.3 Distribution of Transmittal Letters. As soon as practicable, but
in any event no later than ten (10) business days after the Effective Time, the
Exchange Agent will mail by first class mail, postage prepaid, to each Former
Holder (a) a letter of transmittal, substantially in the form attached hereto as
Exhibit B (the "Letter of Transmittal"), and (b) instructions for use in
effecting the surrender of a certificate or certificates which immediately prior
to the Effective Time represented a share or shares of FlowWise Capital Stock
(the "Certificates") in exchange for payments of Merger Consideration.

            8.4 Telephone Requests. The Exchange Agent will accept and comply
with all telephone requests for information relative to the exchange of
Certificates in connection with the Merger.

            8.5 Payments to Former Holders. The Exchange Agent will make the
following payments out of the Exchange Fund to the Former Holders (other than to
holders of Dissenting Shares, if any):

                  (a) Upon the later to occur of (i) the receipt by the Exchange
Agent from a Former Holder of (A) the Certificate(s) or affidavits for lost
certificate(s) as required by Section 1.10 below (the "Securities
Documentation"), together with a properly completed and executed Letter of
Transmittal, (B) a Form W-8 or W-9, as appropriate, properly completed and
signed by such Former Holder, and (C) such other documents as may be reasonably
required by


                                       -3-
<PAGE>

the Exchange Agent (each, a "Documented Former Holder"), or (ii) the Effective
Time, the Exchange Agent will pay to such Former Holder the amount of cash
payable to such Former Holder as described in Section 1.1(c) above in the manner
requested by such Former Holder in the Letter of Transmittal; provided, however,
that the Exchange Agent shall not deliver any amount described in Section 1.1(c)
above by wire transfer of immediately available funds if such amount is less
than One Hundred Thousand Dollars ($100,000). The Exchange Agent shall reserve
for future payment to each Former Holder who has not submitted completed
Securities Documentation and a Letter of Transmittal (each, an "Undocumented
Former Holder") that Former Holder's share of the Initial Merger Consideration.

                  (b) Subject to the provisions of Section 2.2(b) and Article XI
of the Merger Agreement and Section 2.3(c) hereof, as soon as practicable (but
in any event within ten (10) business days) after the expiration of the
Indemnification Period, the Exchange Agent will pay to each of the Documented
Former Holders, the amounts of the Holdback Amount payable to each such holder
as described in Section 1.1(d) hereof as such may be adjusted pursuant to
Section 2.3 hereof, plus interest thereon for the period from the Closing Date
payable in accordance with Section 2.2(b) of the Merger Agreement in the manner
requested by such Former Holder in the Letter of Transmittal or as subsequently
directed by such Former Holder in accordance with the notice provisions hereof;
provided, however, that the Exchange Agent shall not deliver any amount
described in Section 1.1(d) above by wire transfer of immediately available
funds if such amount is less than One Hundred Thousand Dollars ($100,000). The
Exchange Agent shall also reserve for each Undocumented Former Holder his or her
share of the amount referred to in this Section 1.5(b) (for payment upon
becoming a Documented Former Holder).

Notwithstanding anything contained in this Section l.5 to the contrary, the
Exchange Agent shall not issue checks to Former Holders for amounts less than
$10.00, except that the final payment under this Agreement to any Former Holder
shall have no minimum amount. Amounts less than $10.00 allocable to any Former
Holder on any scheduled payment date shall be retained in the Exchange Fund and
cumulate for the benefit of such Former Holder until the earlier of (i) the
first scheduled payment for which the funds in the Exchange Fund allocable to
such Former Holder exceed $10.00 or (ii) the final payment to such Former
Holder.

            8.6 Discrepancies. The Exchange Agent will follow its regular
procedures to reconcile any discrepancies between the number of FlowWise Shares
any Letter of Transmittal may indicate are owned by a surrendering Former Holder
and the number that the Merger Consideration Schedule indicates was owned by the
Former Holder immediately prior to the Effective Time. In any instance where the
Exchange Agent cannot reconcile such discrepancies by following such procedures,
the Exchange Agent will consult with NET for instructions as to the number of
FlowWise Shares, if any, the Exchange Agent is authorized to accept for payment.
In the absence of such instructions, the Exchange Agent is instructed not to
make any payment.

            8.7 Processing Letters of Transmittal. The Exchange Agent will
examine the Letters of Transmittal and Securities Documentation delivered or
mailed to the Exchange Agent to ascertain whether they have been completed and
executed in accordance with the instructions set forth in the Letter of
Transmittal and are in proper form for surrender. In the event any Letter of
Transmittal has not been properly completed or executed or the Securities
Documentation is


                                       -4-
<PAGE>

not in proper form for surrender or there is some other irregularity in
connection with the surrender, the Exchange Agent will follow its regular
procedures to cause such irregularity to be corrected. In instances where any
such irregularity is neither corrected nor waived, as soon as practicable, the
Exchange Agent will return to the surrendering Former Holder (by first class
mail under a blanket surety bond or insurance protecting the Exchange Agent and
Shareholder Representative or by registered mail insured separately for
replacement value, as the Exchange Agent in its sole discretion determines) any
Securities Documentation in connection therewith, together with the Letters of
Transmittal and any other documents relating thereto and a letter of notice
explaining the reasons for the return of the Securities Documentation and other
documents.

            8.8 Date and Time Stamp. Each document received by the Exchange
Agent relating to the Exchange Agent's duties under this Agreement will be date
and time stamped when received.

            8.9 Payment to Person Other than Registered Holder. If payment is to
be made by the Exchange Agent to a person other than the person in whose name
the Securities Documentation is registered, the Exchange Agent will make no
payment until the Letter of Transmittal accompanying the Securities
Documentation has been properly endorsed (or otherwise put in proper form for
transfer), with a proper form of signature guaranty, and the person requesting
such payment has established to the Exchange Agent's satisfaction either (a)
that any transfer and other taxes or governmental charges required by reason of
such payment in a name other than that of the registered holder of the
Securities Documentation have been paid or (b) that no such tax or charge is
payable.

            8.10 Lost, Stolen or Destroyed Certificates. If any Former Holder
reports to the Exchange Agent that his, her or its failure to surrender the
Certificate(s) registered in his, her or its name immediately prior to the
Effective Time according to the Merger Consideration Schedule is due to the
loss, theft or destruction of the Certificate(s), such Former Holder shall
furnish an affidavit for such lost or destroyed Certificate(s) in the form of
Exhibit C hereto (and, if required by NET, the posting by such Former Holder of
a bond in such reasonable amount as NET may direct as indemnity against any
claim that may be made against it with respect to such Certificate(s)). The
Exchange Agent will notify NET prior to making any payment under this Section
1.10, and if NET does not require the posting of a bond within ten (10) business
days of such notification, upon receipt of any such affidavit, the Exchange
Agent may effect payment to the Former Holder pursuant to Section 1.5 above as
though he, she or it had surrendered his, her or its Certificate(s) without any
liability to Exchange Agent.

            8.11 Cancellation of Certificates. Upon the payment to a Former
Holder by the Exchange Agent under Section 1.5(a) above, the Certificate(s)
surrendered by such Former Holder will be physically canceled by the Exchange
Agent and delivered to NET for posting to the shareholder records of FlowWise.

            8.12 Exchange Reports. The Exchange Agent will forward to NET and
the Shareholder Representative reports of the Securities Documentation
surrendered and the aggregate amount of cash paid therefor in the following
manner: (a) a monthly report following the first month after the Closing Date;
(b) a quarterly report following the first (3) months after


                                      -5-
<PAGE>

the Closing Date; and (c) quarterly reports thereafter. If so instructed by the
Shareholder Representative, the Exchange Agent will prepare and forward such a
report on a monthly basis.

            8.13 Tax Reporting. On or before January 31, 1999 and 2000, the
Exchange Agent will prepare and mail to each Former Holder, other than Former
Holders who demonstrate their status as nonresident aliens in accordance with
United States Treasury Regulations, a Form 1099-B and a Form 1099-INT, in
accordance with Treasury Regulations. The Exchange Agent will also prepare and
file copies of such Forms 1099-B and 1099-INT by magnetic tape with the Internal
Revenue Service, in accordance with Treasury Regulations. If the Exchange Agent
has not received notice from the surrendering Former Holder of that Former
Holder's certified taxpayer identification number, the Exchange Agent shall
deduct and withhold backup withholding tax from any cash payment pursuant to
Treasury Regulations. Should any issue arise regarding federal income tax
reporting or withholding, the Exchange Agent will take such action as NET and
the Shareholder Representative jointly instruct the Exchange Agent in writing.
The Shareholder Representative and NET jointly may modify or supplement the
federal tax reporting instructions to the Exchange Agent at any time by notice
in writing and the Exchange Agent shall comply with such modified or
supplemented instructions.

            8.14 Follow-up Letters. No later than six (6) months after the
Effective Time, the Exchange Agent will mail or cause to be mailed a follow-up
letter, substantially in the form attached hereto as Exhibit D (the "Follow-up
Letter"), to all Former Holders who did not theretofore surrender their
Certificates. The follow up letter will be mailed with a Letter of Transmittal
and return envelope.

      9. Escrow Services.

            9.1 Establishment and Investment of the Exchange Fund; Taxation of
Interest. The Exchange Agent agrees to establish the Exchange Fund and to hold
the funds deposited by NET into the Exchange Fund in escrow until such time as
it is required to disburse the funds in such Exchange Fund as herein provided.
The Exchange Agent agrees to invest and reinvest the funds in the Exchange Fund
in money market funds with no less than a AAA rating. Any interest and other
earnings on the Exchange Fund shall be paid to the Former Holders on a pro-rata
basis in accordance with the respective amounts of Merger Consideration received
by each Former Holder. The parties acknowledge that the Exchange Agent shall not
be responsible for any diminution in the Exchange Fund due to losses resulting
from investments. The Exchange Agent may use its own Bond Department in
executing purchases and sales of permissible investments.

            9.2 Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to the holders of Certificates more than six (6)
months after the expiration of the Indemnification Period shall be delivered to
NET, upon written demand, and any Former Holders who have not theretofore
complied with the requirements of Section 1.5(a) above shall thereafter look
only to NET for payment of their claim for the Merger Consideration payable to
such Former Holders pursuant to Section 2.1 of the Merger Agreement, in each
case without interest thereon, except as may apply with respect to the Holdback
Amount.

            9.3 Disposition of Holdback Amount.


                                      -6-
<PAGE>

                  (a) Term of Escrow. Except as provided in this Section 2.3,
the Holdback Amount shall not be released from escrow until the expiration of
the Indemnification Period. At such time, subject to the provisions of this
Section 2.3 and payment of the Shareholder Representative's expenses in
accordance with Section 3.3 below, the Holdback Amount shall be delivered to the
Former Holders in accordance with Section 1.5(b) hereof.

                  (b) Certification of Damages.

                        (i) In the event that NET shall have incurred any
      Damages for which NET wishes to seek adjustment to the Holdback Amount
      pursuant to Section 11.1 of the Merger Agreement, NET shall provide
      written notice to the Shareholder Representative and the Exchange Agent in
      accordance with the terms of Section 11.3(c) of the Merger Agreement. Such
      notice shall (A) state that NET has paid Damages, (B) specify in
      reasonable detail the individual items of Damages included in the amount
      so stated, the date each such item was paid, and the nature of the
      misrepresentation, breach of warranty or covenant or other adjustment to
      the Holdback Amount to which such item is related, and (C) indicate that
      NET is seeking adjustment to the Holdback Amount under Article XI of the
      Merger Agreement.

                        (ii) Within thirty (30) calendar days after delivery of
      NET's notice claiming indemnification, the Shareholder Representative may
      provide written notice to NET and the Exchange Agent that (A) the
      Shareholder Representative (on behalf of the Former Holders) disputes the
      claim for indemnification, or (B) the Shareholder Representative (on
      behalf of the Former Holders) disputes and intends to defend the claim or
      Legal Proceeding giving rise such Damages or potential Damages in
      accordance with Section 11.7 of the Merger Agreement. In either case, the
      Exchange Agent shall make payment with respect to such Damages only in
      accordance with (X) subsequent jointly-written instructions of the
      Shareholder Representative and NET, or (Y) a final non-appealable order of
      a court of competent jurisdiction together with a legal opinion of counsel
      for the presenting party satisfactory to the Exchange Agent to that effect
      that the order is final and non-appealable.

                        (iii) Unless the Shareholder Representative contests
      such claim in writing within thirty (30) calendar days in the manner
      described in subsection (ii) above, the Exchange Agent shall deliver the
      amount stated in NET's notice from (and only to extent of) the remaining
      balance of the Holdback Amount.

                  (c) Notice of Anticipated Damages Prior to Expiration of
Indemnification Period.

                        (i) Notwithstanding anything to the contrary herein, no
      later than the date of the expiration of the Indemnification Period, in
      the event that NET reasonably anticipates that it will have to pay or
      accrue Damages relating to (i) claims for which NET has not provided
      notice pursuant to subsection (b) of this Section


                                      -7-
<PAGE>

      2.3 that NET reasonably believes are indemnifiable under Article XI of the
      Merger Agreement, or (ii) claims for which NET has provided notice
      pursuant to subsection (b) of this Section 2.3 that have not been finally
      resolved in accordance with Article XI of the Merger Agreement, NET shall
      deliver to the Shareholder Representative and the Exchange Agent an
      Officer's Certificate setting forth the information identified in clauses
      (A), (B) and (C) of subsection (b)(i) of this Section 2.3 with respect to
      such claims (including, without limitation, information related to any
      anticipated claims and the Basis for such anticipated Liability).

                        (ii) Within ten (10) calendar days after delivery of
      NET's notice referenced in subsection (i) above, the Shareholder
      Representative may provide written notice to NET and the Exchange Agent
      that (A) the Shareholder Representative (on behalf of the Former Holders)
      disputes the claim for indemnification in accordance with Section 11.3(e)
      of the Merger Agreement. In such case, the Exchange Agent shall not
      deliver any of the Holdback Amount to the Former Holders or NET and shall
      continue to hold the Holdback Amount in escrow, subject to the terms
      hereof, until such time as the Exchange Agent receives written
      instructions from the Neutral Third Party as acknowledged by the
      Shareholder Representative and NET that either (A) the Holdback Amount
      shall remain in escrow and the distribution of the Holdback Amount shall
      be made pursuant to the procedure set forth in subsection (b) of this
      Section 2.3, or (B) the Holdback Amount shall be distributed to the Former
      Holders in accordance with Section 1.5(b) hereof.

                        (iii) Unless the Shareholder Representative contests
      such claim in writing within ten (10) calendar days in the manner
      described in subsection (ii) above, the Exchange Agent shall deliver the
      amount stated in NET's notice from (and only to extent of) the remaining
      balance of the Holdback Amount.

For purposes of this Section 2.3 , the term "NET" shall be deemed to include any
Indemnitee (as such term is defined in the Merger Agreement and used in Article
XI thereof).

      10. Shareholder Representative.

            10.1 Authorization; Removal. From and after the Effective Time, the
Former Holders shall be represented hereunder by the Shareholder Representative.
The Shareholder Representative has been duly authorized to act on the Former
Holder's behalf by the affirmative vote of the holders of a majority of the
shares of FlowWise Capital Stock outstanding immediately prior to the Effective
Time. The Shareholder Representative has the power and authority to bind all of
the Former Holders with respect to the Shareholder Representative's performance
of this Exchange Agreement. A decision, act, consent or instruction of the
Shareholder Representative shall constitute a decision of all Former Holders,
and NET and the Exchange Agent may rely upon any such decision, act, consent or
instruction of the Shareholder Representative as being the decision, act,
consent or instruction of each and every Former Holder. Notice or communications
to or from the Shareholder Representative shall constitute notice to or from
each of the Former Holders. The Shareholder Representative may be changed by the
Former Holders from time to time upon not less than ten (10) business days prior
written notice to NET; provided the Shareholder Representative may not be
removed unless a majority in interest of the Former Holders agree to such
removal and to the identity of the substituted Shareholder Representative.


                                      -8-
<PAGE>

In such event, the substitute Shareholder Representative shall agree in writing
to abide by the terms of this Exchange Agreement, and, upon such written
agreement, all parties hereto shall recognize the substitute as the Shareholder
Representative hereunder. No bond shall be required of the Shareholder
Representative, and the Shareholder Representative shall receive no compensation
for his or her services.

            10.2 Powers and Duties. The Shareholder Representative shall have
the following powers and duties: (a) to give and receive notices and
communications; (b) to employ accountants, attorneys, and other such agents as
the Shareholder Representative may deem available and to pay reasonable
compensation for their services; (c) to agree to, negotiate, enter into
settlements and compromises of, and demand arbitration and comply with orders of
courts and awards of arbitrators with respect to claims for damages under
Article XI of the Merger Agreement; and (d) to take all actions necessary or
appropriate in the judgment of the Shareholder Representative for the
accomplishment of the foregoing. The Shareholder Representative shall not be
liable for any act done or omitted hereunder as Shareholder Representative while
acting in good faith and in a manner not constituting gross negligence, and any
act done or omitted pursuant to the advice of counsel shall be conclusive
evidence of such good faith. The Former Holders shall severally indemnify the
Shareholder Representative and hold him or her harmless against any loss,
liability or expense incurred without gross negligence or bad faith on the part
of the Shareholder Representative and arising out of or in connection with the
acceptance or administration of the Shareholder Representative's duties
hereunder.

            10.3 Expenses of Shareholder Representative. Following the
expiration of the Indemnification Period and subject to the resolution of all
claims of NET in accordance with Section 11 of the Merger Agreement, if any
amounts remain in the Holdback Amount, the Shareholder Representative shall be
entitled to be compensated for his actual out-of-pocket expenses incurred in
connection with the fulfillment of his duties under the Merger Agreement and
hereunder, prior to the distribution of Holdback Amount.

      11. Indemnification of the Exchange Agent. NET and the Former Holders,
severally, shall reimburse, indemnify and hold harmless the Exchange Agent, its
employees and agents (referred to in this Section 4 severally and collectively
as the "Exchange Agent"), from and against any loss, damage, liability or claim
suffered, incurred by, or asserted against the Exchange Agent (including any
amounts paid in settlement of any action, suit, proceeding, or claim brought or
threatened to be brought and including expenses of legal counsel) arising out
of, in connection with or based upon any act or omission by the Exchange Agent
relating in any way to this Agreement or its services hereunder, so long as the
Exchange Agent has acted in good faith and in a manner not constituting gross
negligence. The costs and expenses of enforcing this right of indemnification
shall also be borne by NET and the Former Holders equally; provided, however,
that the Former Holders shall not be required to pay any amounts except from the
Exchange Fund (to the extent available). In the event that any amount is due to
the Exchange Agent pursuant to this Section 4, the Exchange Agent shall have the
right to deduct such amount from the Exchange Fund (to the extent available);
provided, however, that NET shall pay one-half of such amount, either directly
to the Exchange Agent or by reimbursing the Exchange Fund for such amount. If
the Exchange Fund has been distributed to the Former Holders in accordance with
Section 1.5(b) hereof or the funds available in the Exchange Fund are
insufficient to satisfy such obligation, then


                                      -9-
<PAGE>

such indemnification obligation shall be borne by NET. The right of the Exchange
Agent to indemnification hereunder shall survive its resignation or removal as
the Exchange Agent and shall survive the termination of this Agreement by lapse
of time or otherwise.

      12. Fees. All fees and costs of the Exchange Agent shall be paid or
reimbursed from NET when and as incurred. Notwithstanding the foregoing, in the
event that the term of the Indemnification Period is extended in accordance with
Section 2.3(c) hereof, an additional fees and costs incurred in connection
therewith shall be paid out of the Holdback Amount, to the extent such funds are
available, when and as incurred. A copy of the fee schedule of the Exchange
Agent is attached hereto as Exhibit E and incorporated herein by this reference.

      13. Limitations Upon the Exchange Agent's Duties.

            13.1 As the Exchange Agent under this Agreement, the Exchange Agent:

                  (a) will have no duties or obligations other than those
specifically set forth in this Agreement or in a written supplement to this
Agreement delivered by the Shareholder Representative and NET and executed by
the Exchange Agent;

                  (b) will be regarded as making no representations and having
no responsibilities as to the legality, validity, sufficiency, value or
genuineness of any Securities Documentation surrendered to the Exchange Agent
under this Agreement and will not be required to and will make no
representations as to the legality, validity, value or genuineness of the
Merger;

                  (c) will not be obligated to take any legal action under this
Agreement which might, in the Exchange Agent's sole judgment, involve any
expense or liability to it unless the Exchange Agent has been furnished with
indemnity satisfactory to the Exchange Agent;

                  (d) may rely on and be fully protected in acting upon any
certificate, instrument, opinion, notice, letter, telegram or other document or
security delivered to the Exchange Agent and reasonably believed by the Exchange
Agent to be genuine and to have been signed by the proper party or parties and
may take the statements made therein as correct without any affirmative duty of
inquiry or investigation;

                  (e) will not be liable or responsible for any recital or
statement contained in the Letter of Transmittal or any other documents which
are prepared by persons other than the Exchange Agent or its counsel;

                  (f) will not be liable or responsible for any failure on the
part of NET, FlowWise or the Shareholder Representative to comply with any of
their covenants and obligations contained in the Merger Agreement or any other
documents;

                  (g) may rely on and will be protected in acting upon the
written or oral instructions of NET, FlowWise or the Shareholder Representative
and their respective counsel, as the case may be, prior to the Effective Time of
the Merger and the Shareholder Representative or NET and its respective counsel,
as the case may be, after the Effective Time of the Merger with


                                      -10-
<PAGE>

respect to the Exchange Agent's duties under this Agreement, and will not be
liable for any action taken, suffered or omitted by the Exchange Agent under
this Agreement in accordance with any such instructions; and

                  (h) may consult with counsel satisfactory to the Exchange
Agent, and the opinion of such counsel will be full and complete authorization
and protection with respect to action taken, suffered or omitted by the Exchange
Agent under this Agreement in good faith and in accordance with the opinion of
such counsel.

            13.2 In the event any question or dispute arises with respect to the
proper interpretation of the Merger Consideration Schedule, the Merger
Agreement, the Exchange Agent's duties under this Agreement or the rights of any
party hereto or of any Former Holder under the Merger Agreement, the Exchange
Agent will not be required to act and will not be held liable for refusal to act
until the question or dispute has been judicially settled (and the Exchange
Agent may, if the Exchange Agent in its sole discretion deems it advisable, but
will not be obligated to, file a suit in interpleader or for a declaratory
judgment for such purpose) by final judgment rendered by a court of competent
jurisdiction, binding upon NET, FlowWise, the Shareholder Representative and
relevant Former Holders, which is no longer subject to review or appeal, or
settled by a written document in form and substance satisfactory to the Exchange
Agent and executed by each of such parties and Former Holders which, in the
Exchange Agent's opinion, is relevant to the matter. At the Exchange Agent's
option, the Exchange Agent may additionally require for such purpose, but will
not be obligated to require for such purpose, the execution of such written
settlement by the relevant Former Holders and any other parties that may have an
interest in the settlement. Any court order or judgment referred to above shall
be accompanied by a legal opinion of counsel for the presenting party
satisfactory to the Exchange Agent to the effect that such court order or
judgment is final and enforceable and is not subject to further appeal. The
Exchange Agent shall act on such court order and legal opinion without further
question.

      14. Termination of Exchange Agreement; Resignation of Exchange Agent. NET
and the Shareholder Representative may jointly terminate this Agreement at any
time by so notifying the Exchange Agent in writing. The Exchange Agent may
resign at any time by giving written notice thereof to the other parties hereto,
but such resignation shall not become effective until a successor Exchange Agent
shall have been appointed and shall have accepted such appointment in writing.
If an instrument of acceptance by a successor Exchange Agent shall not have been
delivered to the Exchange Agent within thirty (30) days of the giving of such
notice of resignation, the resigning Exchange Agent may petition any court of
competent jurisdiction for the appointment of a successor Exchange Agent. Unless
so terminated, this Agreement shall continue in effect until the date that the
Exchange Fund has been finally distributed pursuant to the terms of this
Agreement. In the event of a termination of this Agreement by NET prior to the
time date that the Exchange Fund has been finally distributed, NET shall appoint
a successor Exchange Agent that will be reasonably acceptable to the Shareholder
Representative and inform the Exchange Agent of the name and address of any
successor Exchange Agent, provided that no failure by NET to appoint such a
successor Exchange Agent shall affect the termination of this Agreement or the
discharge of the Exchange Agent as the Exchange Agent hereunder. Upon any such
termination, the Exchange Agent shall be relieved and discharged of any further


                                      -11-
<PAGE>

responsibilities with respect to its duties hereunder (other than the Exchange
Agent's responsibility to deliver the Former Holder's property to the
Shareholder Representative, to deliver the Exchange Fund to the new Exchange
Agreement and to forward documents to NET pursuant to the following sentence
hereof). Upon payment of all of the Exchange Agent's outstanding fees and
expenses (other than fees and expenses of counsel of the Exchange Agent arising
from any dispute under this Agreement), the Exchange Agent will, upon NET's
written instruction, deliver to the Former Holders any remaining funds which
have been deposited with the Exchange Agent pursuant to this Agreement (if any
so remain for distribution), deliver to NET any records concerning prior
payments to and distributions from the Exchange Fund and exchanges of
Certificates for Merger Consideration and promptly forward, pursuant to NET's
instructions, any Certificates, Letters of Transmittal, or other documents
relating to its previous duties hereunder that the Exchange Agent may receive
after its appointment has so terminated. In the event of a termination of the
Exchange Agent or any successor of the Exchange Agent, the Exchange Agent will
promptly notify any Former Holders who have not been paid hereunder of such
termination, and, if a successor Exchange Agent has been appointed, of the name
and address of such successor.

shall inure to the benefit of the respective parties hereto and their respective
heirs, executors, administrators, successors and permitted assigns; provided,
however, that any heirs, executors, administrators, successors and assigns shall
only be liable for any liabilities hereunder to the extent of the value of the

party may assign its duties and responsibilities hereunder without the written
consent of the other parties thereto. Any company into which the Exchange Agent
may be merged or with which it may be consolidated, or any company to whom the

            15.3 Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of California, without
reference to conflicts of laws principles.

            15.4 Amicable Resolution.

                  (a) To the extent that any misunderstanding or dispute which
arises among the parties hereto cannot be resolved agreeably in a friendly
manner, the dispute will be mediated by a mutually-acceptable mediator to be
chosen by NET, the Shareholder Representative and the Exchange Agent within
thirty (30) days after written notice by one of the parties demanding mediation.
No party may unreasonably withhold consent to the selection of a mediator,
however, by mutual agreement the parties may postpone mediation until each has
completed specified but limited discovery with respect to a dispute. The parties
may also agree to attempt some other form of alternative dispute resolution
("ADR") in lieu of mediation, including by way of example and without limitation
neutral fact-finding or a mini-trial.

                  (b) Any dispute that the parties cannot resolve through
negotiation, mediation or other form of ADR within three (3) months of the date
of the initial demand for it by one of the parties may then be submitted to the
courts for resolution. The use of any ADR procedures will not be construed under
the doctrines of laches, waiver or estoppel to affect adversely the rights of
either party. Nothing in this Section 8.4 will prevent any party from resorting
to judicial proceedings if (i) good faith efforts to resolve the dispute under
these procedures have been unsuccessful or (ii) interim relief from a court is
necessary to prevent serious and irreparable injury to a party or to others.

            15.5 Amendments. Any provision of this Agreement may be amended only
by agreement in writing signed by all of the signatories hereto.

            15.6 Counterparts. This Agreement may be executed in counterparts,
including counterparts transmitted by telecopier or telefax, each of which shall
be deemed an original, but all of which together shall constitute one
instrument.

            15.7 Attorneys' Fees. In the event that any dispute arises with
respect to the subject matter of this Agreement, including a dispute resolved
through arbitration, the prevailing party(ies) shall be entitled to recover from
the losing party(ies) its or their reasonable attorneys' fees and legal costs
and expenses incurred in resolving or settling the dispute.

                      (This space intentionally left blank)
