                          AGREEMENT AND PLAN OF MERGER

                  THIS AGREEMENT AND PLAN OF MERGER (the "AGREEMENT") is made as
of February 16, 1999, between Fluence Technology, Inc., a Delaware corporation
("FLUENCE" or "BUYER"), and Opmaxx, Inc., a Delaware corporation ("OPMAXX" or
the "COMPANY"). Fluence and Opmaxx are each sometimes referred to as a "PARTY"
and collectively as the "PARTIES".

                                    RECITALS

                  A. Fluence, Opmaxx, and their respective Boards of Directors
deem it advisable for Opmaxx to merge with and into Merger Sub (defined below)
in accordance with the terms and provisions of this Agreement (the "MERGER").

                  B. Holders in each class and series of issued and outstanding
Common and Preferred Stock of Opmaxx (collectively, the "OPMAXX STOCK") have
reviewed the terms of this Agreement; holders of at least a majority of the
shares of Opmaxx Class A Common, Series A Preferred, and Series B Preferred
Stock (treated as a single class) and the holders of at least two-thirds of the
Series A Preferred Stock (voting as a separate class) have executed irrevocable
proxies authorizing Douglas L. Goodman to vote their shares in favor of the
Merger.

                  C. As a result of the Merger the holders of the Shares will
receive a portion of eight million dollars ($8,000,000.00) in cash (minus the
amount required to pay in full the outstanding debt of the Company at the
Effective Time of the Merger), as more fully described in and subject to the
specific terms and provisions of this Agreement.

                  D. Immediately prior to the Effective Time of the Merger, all
outstanding vested employee stock options shall be exercised for Common Stock
(all Common Stock and Preferred Stock outstanding immediately prior to the
Effective Time of the Merger being, the "SHARES").

                  E. The transactions contemplated by this Agreement shall be
consummated only if Buyer, in its sole discretion, indicates to the Company its
desire to do so. Prior to or contemporaneously with its decision to consummate
such transactions, Fluence shall incorporate Opmaxx Acquisition Company, Inc., a
Delaware corporation, as its wholly-owned subsidiary ("MERGER SUB").

                  F. This Agreement sets forth the terms and conditions to which
the parties hereto have agreed and further contemplates the consummation of
certain related transactions hereinafter described.


                                                    Agreement and Plan of Merger
                                                                          Page 1

                                    AGREEMENT

                  NOW, THEREFORE, in consideration of the premises and the
mutual promises and covenants of the parties hereto, and subject to the terms
and conditions set forth herein, the parties herein agree as follows:

                  1.       DEFINITIONS.

                  Certain terms used in this Agreement and the Exhibits hereto
are specifically defined herein or therein. Unless elsewhere defined in this
Agreement or the Exhibits, these definitions are set forth or referred to in
EXHIBIT A of this Agreement.

                  2.       REORGANIZATION AND MERGER.

                  Subject to the terms and conditions of this Agreement, the
parties hereto agree that, following the Closing (as defined in Section 3
below), Merger Sub and Opmaxx shall execute and file the Certificate of Merger
in substantially the form attached hereto as EXHIBIT B with the Delaware
Secretary of State, whereupon Opmaxx shall be merged with and into Merger Sub
and Merger Sub shall be the surviving corporation in such merger and shall
become a wholly owned subsidiary of Fluence. The parties intend that the Merger
shall be accounted for using the purchase method of accounting.

                  2.1      SURVIVING CORPORATION.

                  Upon the effectiveness of the Merger (hereinafter referred to
as the "EFFECTIVE TIME OF THE MERGER"), Opmaxx shall be merged with and into
Merger Sub and the separate existence of Opmaxx shall cease. Merger Sub shall be
the corporation surviving the Merger.

                  2.2      CERTIFICATE OF INCORPORATION AND BYLAWS OF OPMAXX.

                  The Certificate of Incorporation and Bylaws of Merger Sub at
and immediately prior to the Effective Time of the Merger (as restated to effect
a change of name to "Opmaxx, Inc."), shall be the Certificate of Incorporation
and Bylaws of Merger Sub following the Effective Time of the Merger.

                  2.3      COMMON STOCK OF MERGER SUB.

                  Each share of the common stock of Merger Sub (the "MERGER SUB
COMMON STOCK") issued and outstanding immediately prior to the Effective Time of
the Merger shall, by virtue of the Merger and without any action on the part of
any holder thereof, continue to be one share of Merger Sub Common Stock.

                                                    Agreement and Plan of Merger
                                                                          Page 2

                  2.4      MERGER CONSIDERATION ALLOCATION AND CANCELLATION OF
                           THE SHARES.

                  Subject to the other terms of this Section 2, each of the
Shares shall, by virtue of the Merger and without any action on the part of any
holder thereof, be converted into the right to receive a portion of the
$8,000,000.00 Merger Consideration (the "MERGER CONSIDERATION"), and each of the
Shares shall be deemed canceled and retired. The Merger Consideration shall be
allocated among the outstanding debt of the Company immediately prior to the
Effective Time of the Merger, the Class A Common Stock, the Class B Common
Stock, the Series A Preferred Stock and the Series B Preferred Stock as
indicated on EXHIBIT C. The Company and the Opmaxx Common Stockholders hereby
fully exculpate and indemnify Buyer and its officers, directors, advisors,
representatives and affiliates from any and all claims in any way related to the
allocation of the Merger Consideration and the Additional Merger Consideration
amongst holders of the Shares.

                  2.5      CONVERSION OF OPMAXX OPTIONS.

                  Subject to the other terms of this Section 2, each of the
unvested options outstanding immediately prior to the Effective Time of the
Merger ("OPMAXX OPTIONS") to purchase Opmaxx Common Stock shall, by virtue of
the Merger and without any action on the part of any holder thereof, be
converted into the right to acquire that number of shares of Fluence Stock
determined by multiplying the number of shares of Opmaxx Stock into which such
Opmaxx Options are convertible immediately prior to the Effective Time of the
Merger by the Option Conversion Number (as defined below), at an exercise price
per share of Fluence Common Stock equal to the exercise price per share of such
Opmaxx Option divided by the Option Conversion Number, subject to the provisions
of Section 2.7 regarding the elimination of fractional shares. Each Opmaxx
Option and the Opmaxx 1997 Stock Option/Issuance Plan shall be assumed by
Fluence. The Option Conversion Number shall be the fair market value of a share
of Common Stock of Opmaxx, without regard to class, divided by the fair market
value of one share of Fluence Common Stock on the day of Closing. The fair
market value of one share of Common Stock of Opmaxx and Fluence on the date of
Closing shall be determined by an independent third party mutually agreeable to
Fluence and Opmaxx. If they cannot agree on an appraiser, Fluence and Opmaxx
shall each select an appraiser and those appraisers shall select a third
appraiser whose determination of fair market value shall be binding on the
parties. It is a condition to Fluence's assumption under this paragraph that
each holder of unvested options to purchase Opmaxx Common Stock shall have
furnished Fluence with a signed waiver agreement (in form and substance
satisfactory to Fluence) in which such person, as consideration for the
assumption of his or her Opmaxx Options by Fluence in the Merger, waives any and
all right he or she may otherwise have under the Agreement or the agreements
evidencing his or her Opmaxx Options or otherwise, to receive any portion of the
Merger Consideration or Additional Merger Consideration upon the subsequent
exercise of the assumed options which would reflect, or otherwise compensate
such person for, the cash consideration payable per share of Opmaxx Common Stock
to the actual holders of Opmaxx Common Stock in conversion of their shares of
such Common Stock in the Merger.


                                                    Agreement and Plan of Merger
                                                                          Page 3

                  2.6      EXCHANGE OF STOCK CERTIFICATES.

                  At the Effective Time of the Merger, Opmaxx and Fluence shall
submit to Fluence's registrar and transfer agent, Marianne Brannock at Credence
Systems Corporation, 215 Fourier Avenue, Fremont, CA 94539 (the "EXCHANGE
AGENT"), an instruction letter including a list of the names, addresses and
social security numbers/taxpayer identification numbers or other appropriate
documentation of each holder of shares of Opmaxx Stock outstanding immediately
prior to the Effective Time of the Merger. As soon as reasonably practicable
following the Effective Time of the Merger, Fluence shall cause the Exchange
Agent to cause each such Opmaxx Stockholder to receive, in exchange for the
Opmaxx Stock held by such Opmaxx Stockholder, a cash payment representing the
Opmaxx Stockholder's share of the Merger Consideration as determined by the type
or types of securities of Opmaxx held and exchanged by such stockholder and by
reference to EXHIBIT C. A holder of Opmaxx Stock whose stock certificate(s) have
been lost or destroyed shall, upon providing satisfactory evidence of ownership
of such shares and appropriate indemnification, have the right to the delivery
of the appropriate cash amount.

                  2.7      TRANSFER BOOKS.

                  The stock transfer books of Opmaxx pertaining to Opmaxx Stock
outstanding at the Effective Time of the Merger shall be closed at the Effective
Time of the Merger, and thereafter no transfer of any such shares of Opmaxx
Stock shall be recorded thereon.

                  2.8      OPMAXX DISSENTING SHARES.

                  Opmaxx Stockholders holding any shares of Opmaxx stock that
are eligible to be "DISSENTING SHARES" within the meaning of the Delaware
General Corporate Law ("DELAWARE CODE") with respect to the Merger and as to
which dissenter's rights to require the purchase of such shares have been
properly exercised will be entitled to their rights under the Delaware Code with
respect to such shares. Merger Sub shall pay all amounts to which dissenting
stockholders of Opmaxx may be entitled by reason of the Merger. Shares of Opmaxx
Stock as to which dissenting stockholders' rights of appraisal have not been
properly perfected under the Delaware Code will be converted to cash as provided
in Section 2.4 above.

                  2.9      FURTHER ASSURANCES.

                  Fluence and Opmaxx agree that if, at any time after the
Effective Time of the Merger, any further deeds, assignments or assurances are
reasonably necessary or desirable to be obtained from Opmaxx, Fluence or its
officers or directors, to consummate the Merger or to carry out the purposes of
this Agreement at or after the Effective Time of the Merger, then Fluence,
Opmaxx and their respective officers and directors shall execute and deliver all
such proper deeds, assignments and assurances and do all other things necessary
or desirable to consummate the Merger and to carry out the purposes of this
Agreement, in the name of Opmaxx, Fluence or otherwise.

                  8.       COVENANTS OF THE BUYER

                  8.1      AFFIRMATIVE COVENANTS

                  (a) Buyer agrees to extend credit to the Company up to a
maximum amount of $1,750,000. One million one hundred and fifty thousand dollars
($1,150,000) of such credit has already been provided. The remaining $600,000 of
credit will be made available to the Company immediately upon execution of this
Agreement, on a revolving basis, for use by the Company at any time, from time
to time, and for any reason, provided that the Company's withdrawals be made in
increments of $50,000 or more (or, if less than $50,000 of the original $750,000
credit facility remains, then that lesser amount). Buyer agrees to disburse the
amount requested by the Company within five (5) business days of receiving the
Company's request. The additional $600,000 in revolving credit will be evidenced
by a promissory note substantially in the form of Exhibit G attached hereto, and
secured by certain assets of the Company as provided in the existing Security
Agreement between the parties.

                  (b) Buyer agrees to forgive fifty percent (50%) of the
outstanding loan amount owed by the Company pursuant to Section 8.1(a) as of the
termination date of this Agreement indicated in Section 11.6, provided that: (i)
Buyer has not obligated itself to consummate the transactions contemplated by
this Agreement prior to such date by providing notice to the Company of its
intent to do so prior to December 31, 1999; and (ii) the Company is not in
material breach of any covenants set forth in Section 7 hereof as of the
termination date.

                  (c) During the term of this Agreement and throughout the
period in which Additional Merger Consideration may be earned pursuant to
Section 9, Buyer agrees to take necessary steps to cause the worldwide sales and
distribution organization of its parent corporation, Credence Systems
Corporation ("Credence"), to participate in sales efforts to promote the
Company's Products as it promotes Buyer's products.

                  (d) During the term of this Agreement and throughout the
period in which Additional Merger Consideration may be earned pursuant to
Section 9, Buyer agrees that its worldwide sales and distribution organization
will pursue sales of the Company's Products as it pursues sales of its own
products.

                  (e) During the term of this Agreement and throughout the
period in which Additional Merger Consideration may be earned pursuant to
Section 9, Buyer agrees that its marketing organization will promote the
Company's Products as it promotes its own products.

                  (f) During the term of this Agreement and throughout the
period in which Additional Merger Consideration may be earned pursuant to
Section 9, Buyer agrees that its marketing communications organization will
support promotion of the Company's Products through trade shows, press releases,
and the like, at no charge and as requested by the Company.

                  (g) Buyer agrees that within six (6) months after execution of
this Agreement, it will make available to the Company at no charge, four (4)
software engineers to perform

                                                    Agreement and Plan of Merger
                                                                         Page 10
<PAGE>

development work for the Company. Buyer agrees that these four engineers will be
available to the Company on an exclusive basis, and will remain so until
termination of this Agreement. Buyer further agrees that the work product of
these four engineers will be the sole and exclusive intellectual property of the
Company (notwithstanding their employment status), and that Buyer will take all
actions and execute any further agreements necessary to ensure that such work
product remains the sole and exclusive property of the Company, including,
without limitation, requiring each of such engineers to execute confidentiality
and development agreements in the Company's favor and the appropriate
assignments of intellectual property.

                  (h) During the term of this Agreement and throughout the
period in which Additional Merger Consideration may be earned pursuant to
Section 9, Buyer agrees to take necessary steps to cause Credence to provide a
source code copy of its Analog Wave Tool to the Company at no charge for
development purposes, and to license the Company to distribute binary executable
versions of the Analog Wave Tool to its customers.

                  9.  ADDITIONAL MERGER CONSIDERATION

         The Opmaxx Common Stockholders shall be entitled to receive the
following amounts in addition to the Merger Consideration:

                  9.1 DEFINITION OF NET RECEIPTS FOR PAYMENT OF ROYALTIES. The
term "NET RECEIPTS" shall mean any money actually received by Buyer from the
sale, lease, rental, license or other commercial exploitation of the Products,
including maintenance fees, but excluding fees for engineering consulting
services and after deduction of all amounts related to returns and allowances
and uncollectible accounts. The term "PRODUCTS", as used herein, shall mean the
computer software programs sold or under development by Opmaxx or on the Opmaxx
sales price list as of the Closing Date as such Products are further developed,
extended, modified, enhanced and otherwise customized after the Closing. The
term Products shall also include all present and future enhancements,
corrections, modifications, upgrades, variations, revisions, improvements,
translations in human or machine-readable languages and codes, conversions,
derivatives, new versions or releases of or to the Products at any time
developed after the Closing. Buyer agrees not to incorporate products, whether
developed by Buyer or alternative sources, into its distribution that reduces
the expected revenue stream from the Additional Merger Consideration.

                  9.2 PAYMENT OF ADDITIONAL MERGER CONSIDERATION. Subsequent to
the Closing, Buyer shall be obligated to pay to the Escrow Agent within
forty-five (45) days of the end of each calendar quarter additional Merger
Consideration (the "ADDITIONAL MERGER CONSIDERATION") equal to ten percent (10%)
of Net Receipts for sales of the Products from the Closing Date through December
31, 2003. Such payments of Additional Merger Consideration are required for all
sales made through December 31, 2003, even if payments for such sales are not
received until a later date. The Additional Merger Consideration payments will
be held, administered, and disbursed by the Escrow Agent, subject to offset
according to Section 10.3, pursuant to the terms of the Escrow Agreement.

                                                    Agreement and Plan of Merger
                                                                         Page 11
<PAGE>

                  9.3  BUNDLED SALES OF THE PRODUCTS. In the event the Company's
successor sells, rents, leases or sublets the Products in conjunction with other
products where the Products are not separately itemized and invoiced, then the
Opmaxx Common Stockholders shall be entitled to receive, and Buyer shall be
obligated to pay, Additional Merger Consideration, at the applicable rate set
forth in Section 9.2 above, based upon the proportionate percentage of the
catalog value of the Product or Products in relation to the aggregate catalog
value of the Product or Products and the other products sold and invoiced as a
bundled package.

                  9.4  RECORDS. Buyer covenants and agrees to maintain adequate
records of all transactions contemplated hereby, subject to the Nondisclosure
Agreement. The Common Stockholder Representative shall be entitled to audit and
examine the records maintained by Buyer in connection with the transactions
contemplated hereby at Buyer's principal executive offices during customary
business hours and upon five (5) business days' prior notice, and to make copies
of said financial records of Buyer reflecting transactions directly related to
sale of the Products. The Common Stockholder Representative shall pay for costs
of any audits conducted by the Common Stockholder Representative, except that if
Buyer's royalty calculations are determined to be greater than 2% in error,
Buyer shall pay the costs of such audit.

                  9.5  GOOD FAITH EFFORTS. Buyer covenants and agrees to provide
the funding, staffing and support necessary or desirable to further develop,
market, and distribute the Products at least equivalent to the funding, staffing
and support expended by the Company prior to the Merger.

                  10.  INDEMNIFICATION

                  10.1 SURVIVAL OF REPRESENTATIONS, WARRANTIES, COVENANTS AND
                       AGREEMENTS.

                  (a) Notwithstanding any investigation conducted at any time
with regard thereto by or on behalf of any party to this Agreement, all
representations and warranties of the Company and the Buyer shall survive the
execution, delivery, and performance of this Agreement until January 1, 2004. No
investigation made by or on behalf of Buyer with respect to the Company shall be
deemed to affect Buyer's reliance on the representations, warranties, covenants
and agreements made by the Company contained in this Agreement and shall not be
a waiver of Buyer's right to indemnity as herein provided for the breach or
inaccuracy of or failure to perform or comply with any of the Company's
representations, warranties, covenants or agreements in this Agreement. No
investigation made by or on behalf of the Company with respect to the Buyer
shall be deemed to affect the Company's reliance on the representations,
warranties, covenants and agreements made by the Buyer contained in this
Agreement and shall not be a waiver of the Company's right to indemnity as
herein provided for the breach or inaccuracy of or failure to perform or comply
with any of the Buyer's representations, warranties, covenants or agreements in
this Agreement.

                                                    Agreement and Plan of Merger
                                                                         Page 12
<PAGE>

                  (b) Nothing in this Agreement shall be construed as limiting
in any way the remedies that may be available to a party in the event of fraud
relating to the representations, warranties, agreements or covenants made by any
other party in this Agreement.

                  (c) Notwithstanding anything in this Agreement to the
contrary, the Company shall have liabilities and obligations for Claims and
Liabilities (as defined herein) under this Section 10 only with respect to
claims submitted or notices of claims provided to the Escrow Agent and the
Common Stockholder Representative on or before December 31, 2003.
Notwithstanding the expiration date of the representations, warranties,
covenants and agreements set forth herein, if Buyer shall notify the Escrow
Agent and the Common Stockholder Representative with respect to the submission
of a claim prior to January 1, 2004, the Company's liability or obligation for
Claims and Liabilities shall continue in full force and effect until settled in
accordance with the terms and conditions of the Escrow Agreement.

                  10.2     INDEMNIFICATION OF FLUENCE

                  Subject to the limitations contained in this section, the
Opmaxx Common Stockholders shall indemnify and hold harmless Fluence, its
affiliates, officers, directors, stockholders, employees and agents from and
against any and all losses, claims, judgments, liabilities, demands, charges,
suits, penalties, costs or expenses, including court costs and attorneys' fees
("CLAIMS AND LIABILITIES") with respect to or arising from (i) the breach of any
warranty or any inaccuracy of any representation made by Opmaxx in this
Agreement, or (ii) the breach of any covenant or agreement made by Opmaxx in
this Agreement. The Company shall not have breached a representation or warranty
in this Agreement to the extent that the Company became required to disclose a
new item or matter on the Revised Disclosure Schedule if the Company learns of
the fact, condition or circumstance requiring such disclosure after the date of
this Agreement and prior to Closing.

                  10.3     LIMITATIONS TO THE INDEMNIFICATION OF FLUENCE

                  Anything to the contrary notwithstanding, Fluence shall not be
indemnified and held harmless in respect of any Claims and Liabilities which are
covered by insurance owned by Opmaxx to the extent that any net loss is reduced
by such insurance. Fluence's recourse in respect of its right to indemnity by
and from the Opmaxx Common Stockholders shall be limited to the Additional
Merger Consideration held or to be deposited into escrow under the Escrow
Agreement; Fluence's indemnity shall not extend to Additional Merger
Consideration once it is paid out to the Opmaxx Common Stockholders pursuant to
the Escrow Agreement. Fluence shall not be permitted to enforce any claim for
indemnification under this Section 10 until the aggregate amount of Claims and
Liabilities exceeds $50,000 (the "THRESHOLD"). Once Claims and Liabilities in
excess of the Threshold have been asserted by Fluence, all Claims and
Liabilities above that amount may be pursued by Fluence unless otherwise limited
by this Agreement or the Escrow Agreement, provided, however, that the Agreement
will control in the case of any conflicts between it and the Escrow Agreement.
The parties understand and agree that: (i) the obligation of the Opmaxx Common
Stockholders to indemnify Fluence and its related parties as provided in this
Section 10 shall be the exclusive remedy for Fluence and such

                                                    Agreement and Plan of Merger
                                                                         Page 13
<PAGE>

related parties in the event of any breach of any express or implied
representation, warranty or covenant of Opmaxx under this Agreement; (ii) the
only recourse for Fluence and such related parties to enforce such
indemnification obligations shall be through the Escrow Agreement against the
Additional Merger Consideration; and (iii) the indemnity obligations of the
Opmaxx Common Stockholders under this Section 10 shall terminate after 11:59
p.m. (PST) on December 31, 2003, except insofar as Fluence has properly asserted
a claim for indemnification under this Section 10 and pursuant to the terms of
the Escrow Agreement and such claim has not been resolved in accordance with the
terms of the Escrow Agreement.

                  10.4     INDEMNIFICATION OF OPMAXX

                  Fluence shall defend, indemnify and hold harmless Opmaxx, and
its officers, directors, stockholders, employees and agents against and in
respect to all Claims and Liabilities with respect to or arising from (i) breach
of any warranty or any inaccuracy of any representation made by Fluence, or (ii)
breach of any covenant or agreement made by Fluence in this Agreement.

                  10.5     LIMITATIONS TO THE INDEMNIFICATION OF OPMAXX

                  Anything to the contrary notwithstanding, Opmaxx shall not be
indemnified and held harmless in respect of any Claims and Liabilities which are
covered by insurance owned by Fluence to the extent that any net loss is reduced
by such insurance. Opmaxx shall not be permitted to enforce any claim for
indemnification under this Section 10 until the aggregate amount of Claims and
Liabilities exceeds the Threshold indicated in Section 10.3. Once Claims and
Liabilities in excess of the Threshold have been asserted by Opmaxx, all Claims
and Liabilities above that amount may be pursued by Opmaxx unless otherwise
limited by this Agreement. The parties understand and agree that the indemnity
obligations of Fluence under this Section 10 shall terminate after 11:59 p.m.
(PST) on December 31, 2003, except insofar as Opmaxx has properly asserted a
claim for indemnification under this Section 10.

                  11.      MISCELLANEOUS

                  11.1     SUCCESSORS AND ASSIGNS.

                  The provisions of this Agreement shall inure to the benefit

remedies, obligations, or liabilities under or by reason of this Agreement,
except as expressly provided in this Agreement.

                  This Agreement shall be governed by and construed under the
laws of the State of Oregon without giving effect to any choice of law rule that

internal laws of the State of Oregon to the rights and duties

                                                    Agreement and Plan of Merger

of the Parties hereunder. Any disputes arising among the Parties in
connection with this Agreement shall be settled by the Parties amicably through
good faith discussions upon the written request of any Party. In the event that
any such dispute cannot be resolved through such discussions within a period of
sixty (60) days after delivery of such notice, the dispute shall be finally
settled by arbitration in Portland, Oregon, in accordance with the rules then in
effect of the American Arbitration Association. The arbitrator(s) shall have the
authority to grant specific performance, and to allocate between the Parties the
costs of arbitration in such equitable manner as the arbitrator(s) may
determine. The prevailing party in the arbitration shall be entitled to receive
reimbursement of its reasonable expenses incurred in connection therewith.
Judgment upon the award so rendered may be entered in any court having
jurisdiction or application may be made to such court for judicial acceptance of
any award and an order of enforcement, as the case may be.

                  If any provision in this Agreement shall be found or be held
to be invalid or unenforceable then the meaning of said provision shall be
construed, to the extent feasible, so as to render the provision enforceable,
and if no feasible interpretation would save such provision, it shall be severed
from the remainder of this Agreement which shall remain in full force and effect
unless the severed provision is essential and material to the rights or benefits
received by any Party. In such event, the Parties shall use best efforts to
negotiate, in good faith, a substitute, valid and enforceable provision or
agreement which most nearly affects the Parties' intent in entering into this
Agreement.

                  11.8     FURTHER ASSURANCES.

                  A. Opmaxx and Fluence have entered into an Agreement and Plan
of Merger dated as of February 16, 1999, (the "Plan"), pursuant to which Opmaxx
Acquisition Corporation ("Merger Sub"), a wholly-owned subsidiary of Fluence to
be formed by Fluence prior to or contemporaneously with consummation of the

Stockholders entitled to receive Additional Merger Consideration as more fully

                  B. The Plan provides that the Additional Merger Consideration

secure the indemnification obligations under Section 10 of the Plan.

                  C. The parties desire to enter into this Agreement to

                  "Termination Date" means January 1, 2004, the date on which
the parties' indemnification obligations expire pursuant to Section 10.1 of the
Plan.

                  2.       FORMATION OF ESCROW ACCOUNTS.

                  2.1      DELIVERY AND DEPOSIT OF ADDITIONAL MERGER
                           CONSIDERATION.

                  Upon the execution of this Agreement by all parties hereto,
and until the Termination Date, Fluence will deliver to the Escrow Agent the
Additional Merger Consideration in the manner specified in Section 9.2 of the
Plan. The Escrow Agent agrees to accept delivery of the above-mentioned
Additional Merger Consideration, and to hold the same in escrow in an escrow
account (the "Escrow Account"), subject to the terms and conditions of this
Agreement.

                  2.2      TREATMENT OF ADDITIONAL MERGER CONSIDERATION.

                  The Additional Merger Consideration shall be held by the
Escrow Agent and shall not be subject to any lien, attachment, trustee process
or any other judicial process of any creditor of any party hereto.

                  3.       ADMINISTRATION OF ESCROW ACCOUNT.

Consideration in an account bearing interest at a rate not less than the daily
money market rate at U.S. Bank National Association (or similar bank).

                  3.2      CLAIM NOTICE.

                  If Fluence asserts a claim for indemnification under Section
10 of the Plan on or prior to the Termination Date, then Fluence shall promptly
give written notice of such claim (a "Claim Notice"), including a copy of such
claim and/or process and all legal pleadings in connection therewith, to the
Common Stockholder Representative and the Escrow Agent in accordance with
Section 11 hereof. Each Claim Notice shall state the amount of claimed Claims
and Liabilities (the "Claimed Amount") and the basis for such claim. Fluence
shall assert any claim for indemnification promptly following its discovery of
the facts giving rise to such claim and in no event more than sixty (60) days
from such discovery so long as such period does not extend beyond the
Termination Date of this Agreement.

                                                                Escrow Agreement
                                                                          Page 2
<PAGE>

                  3.3      RESPONSE NOTICE.

                  Within thirty (30) days after delivery of a Claim Notice to
the Common Stockholder Representative, the Representative shall give to Fluence,
with a copy to the Escrow Agent, a written response (the "Response Notice") in
which the Representative shall either:

                  (a) agree to the full Claimed Amount and instruct the Escrow
Agent to release and deliver such portion of the Additional Merger Consideration
having a value equal to the full Claimed Amount from the Escrow Account to
Fluence; or

                  (b) agree to a portion of the Claimed Amount (the "Agreed
Amount") and instruct the Escrow Agent to release and deliver such portion of
the Additional Merger Consideration having a value equal to the Agreed Amount
from the Escrow Account to Fluence, and contest the remainder of the Claimed
Amount and instruct the Escrow Agent to hold present and future, if necessary,
portions of the Additional Merger Consideration equal to such contested amount
in the Escrow Account until such contested amount is resolved pursuant to
Section 4 below; or

                  (c) contest the full amount of the Claimed Amount and instruct
the Escrow Agent to hold present and future, if necessary, portions of the
Additional Merger Consideration equal to such contested amount in the Escrow
Account until such contested amount is resolved pursuant to Section 4 below.

         The Representative may contest the Claimed Amount and withhold release
of Additional Merger Consideration only based upon a good faith belief that all
or such portion of the Claimed Amount does not constitute Claims and
Liabilities, or does not constitute the actual amount of Claims and Liabilities
incurred, for which Fluence is entitled to indemnification under Section 10 of
the Plan. If no Response Notice is delivered by the Representative within such
thirty (30) day period, then the Representative shall be deemed to have agreed
that the full Claimed Amount may be released and delivered from the Escrow
Account to Fluence.

                  3.4      RELEASE WITHOUT CONTEST.

                  (a) If in his Response Notice the Representative agrees (or if
the Representative fails to deliver a Response Notice within the required time
period and as such is deemed to have agreed) that the Additional Merger
Consideration having a value equal to the full Claimed Amount may be released
from the Escrow Account to Fluence, then the Escrow Agent shall promptly
thereafter deliver to Fluence from the Escrow Account Additional Merger
Consideration having a value equal to the Claimed Amount (or such lesser amount
as is then held in the Escrow Account).

                  (b) If the Representative in the Response Notice agrees that
Additional Merger Consideration having a value equal to the Agreed Amount may be
released from the Escrow Account to Fluence in the respective amounts set forth
in the Response Notice, then the Escrow Agent shall promptly thereafter deliver
to Fluence such Agreed Amount from present and future, if necessary, portions of
the Additional Merger Consideration, and the provisions of Section 4 shall apply
to any and all of the Claimed Amount being contested by the Representative.


                                                                Escrow Agreement
                                                                          Page 3

                  4.1      ARBITRATION OF DISPUTES OVER ESCROW RELEASE.

         If the Representative gives a Response Notice contesting the release of
Additional Merger Consideration equal to all or any part of the Claimed Amount
set forth in the applicable Claim Notice, as provided in Sections 3.3(b) and (c)
above (the "Contested Amount"), then such dispute shall be settled by mandatory
binding arbitration pursuant to the terms of Section 11.2 of the Plan.

                  4.2      ACTIONS OF ESCROW AGENT PENDING ARBITRATION.

                  Upon receipt of a Claim Notice from Fluence, the Escrow Agent
shall continue to hold in the Escrow Account Additional Merger Consideration
having a value sufficient to cover the Claimed Amount from present and future,
if necessary, deposits of such from Fluence, notwithstanding the intervening
expiration of a calendar quarter or the occurrence of the Termination Date,
until: (a) receipt of a Response Notice instructing the Escrow Agent to release
and deliver an amount of such Additional Merger Consideration equal to all or a
portion of such Claimed Amount from the Escrow Account to Fluence; (b) delivery
of a copy of a settlement agreement executed by Fluence and the Representative
setting forth instructions to the Escrow Agent as to the release of such
Additional Merger Consideration that shall be made with respect to any Contested
Amount; (c) delivery of a copy of the final decision of the arbitrator setting
forth instructions to the Escrow Agent as to the release of Additional Merger
Consideration that shall be made with respect to any Contested Amount; or (d)
receipt of a court order or judgment directing Escrow Agent to act with respect
to the distribution of any Additional Merger Consideration. The Escrow Agent
shall thereupon release Additional Merger Consideration from the Escrow Account
in accordance with such Response Notice, settlement agreement, arbitrator's
instructions, court order or judgment, as applicable.

                  4.3      NO RESPONSIBILITY OF ESCROW AGENT TO RESOLVE DISPUTE.

                  If any controversy arises involving any party to this
Agreement (other than the Escrow Agent) concerning the subject matter of this
Agreement, including a Contested Amount, the Escrow Agent will not be required
to determine the controversy or to take any action until such dispute has been
resolved.

                  4.4      BURDEN OF PROOF.

                  For any claim submitted to an arbitration hereunder, the
burden of proof will be as it would be if the claim were litigated in a judicial
proceeding.

                                                                Escrow Agreement
                                                                          Page 4

                  5.       PAYMENT OF REMAINING ADDITIONAL MERGER CONSIDERATION
TO OPMAXX COMMON STOCKHOLDERS.

                  5.1      QUARTERLY DISBURSEMENTS.

                  At the end of each calendar quarter (and on the Termination
Date), the Escrow Agent shall deliver to Fluence and the Representative a
statement summarizing the Additional Merger Consideration deposited into the
Escrow Account that quarter by Fluence, the interest accrued in the Escrow
Account that quarter, and the total amount of all Claimed Amounts made pursuant
to Sections 3 or 4 hereof in connection with the Escrow Account (the excess, if
any, of such balance in such Escrow Account over the total amount of such
Claimed Amounts against such Escrow Account shall be referred to as the "
Quarterly Escrow Balance"). Fluence and the Representative each shall review the
accuracy of the Quarterly Escrow Balance and notify the Escrow Agent and each
other of any asserted discrepancy or of the absence of any discrepancy within
ten (10) business days of receipt of the foregoing statement. Upon the Escrow
Agent's notification of no discrepancy by Fluence and the Representative within
the ten (10) business day period specified in the preceding sentence, then
within ten (10) business days thereafter, the Escrow Agent shall deliver to each
of the Opmaxx Common Stockholders an amount of the Additional Merger
Consideration representing such Opmaxx Common Stockholder's share of the
Quarterly Escrow Balance less a portion of the accrued interest allocable, on a
proportional basis, to the Claimed Amounts, free and clear of the Escrow created
by this Agreement. If either Fluence or the Representative notifies the Escrow
Agent of a discrepancy, any dispute with respect to such discrepancy shall be
resolved by mandatory binding arbitration as provided in Section 4. After the
last claim shall have been resolved pursuant to Sections 3 and 4 hereof and all
Additional Merger Consideration deliverable to Fluence upon the resolution of
all such Claimed Amounts and their allocated interest have been delivered to
Fluence, the remaining balance, if any, of the Additional Merger Consideration
shall be delivered by the Escrow Agent to each Opmaxx Common Stockholders free
and clear of the Escrow created by this Agreement.

                  5.2      DISTRIBUTION OF THE ADDITIONAL MERGER CONSIDERATION.

                  All distributions of Additional Merger Consideration to the
Opmaxx Common Stockholders to be made by the Escrow Agent under this Section 5
shall be made in the amounts specified in Exhibit C to the Plan.

                  5.3      DELIVERY METHODS.

                  Delivery of Additional Merger Consideration by the Escrow
Agent shall be by registered mail or by nationally recognized overnight courier.
The Escrow Agent shall not be responsible for obtaining insurance in connection
with such delivery.

                  6.       FEES AND EXPENSES OF ESCROW AGENT.

                  6.1      ESCROW AGENT FEES.

                  All fees of the Escrow Agent for the services to be rendered
by the Escrow Agent hereunder, will be paid fifty percent (50%) by Fluence and
fifty percent (50%) by the Opmaxx

                                                                Escrow Agreement
                                                                          Page 5
<PAGE>

Common Stockholders. Fees owed by the Opmaxx Common Stockholders under this
Section 6 shall be paid out of the Additional Merger Consideration.

                  6.2      ESCROW AGENT'S EXTRAORDINARY FEES.

                  Fluence and the Representative hereby acknowledge that all
fees and usual charges for services of the Escrow Agent hereunder shall be
considered compensation for ordinary services as contemplated by this Agreement.
In the event that the Escrow Agent renders any service not provided for in this
Agreement, or if the parties hereto request a substantial modification of the
terms of this Agreement, or if any controversy arises and the Escrow Agent is
made a party to any litigation pertaining to this Agreement or its subject
matter, then the Escrow Agent shall be reasonably compensated for such
extraordinary services and reimbursed for all reasonable costs, attorney's fees
and expenses incurred by the Escrow Agent in rendering such extraordinary
services, which costs, fees and expenses shall be borne by Fluence and the
Opmaxx Common Stockholders as provided in Section 6.1 above.

                  7.       LIABILITY AND AUTHORITY OF REPRESENTATIVE; SUCCESSORS
                           AND ASSIGNEES.

                  7.1      LIMITS ON LIABILITY.

                  The Representative shall incur no liability with respect to
any action taken or suffered by him in his capacity as Representative in
reliance upon any note, direction, instruction, consent, statement or other
documents believed by him to be genuinely and duly authorized, nor for other
action or inaction except his own willful misconduct or gross negligence. The
Representative may, in all questions arising under this Escrow Agreement, rely
on the advice of counsel, and for anything done, omitted or suffered in good
faith by the Representative based on such advice, the Representative shall not
be liable to anyone.

                  7.2      SUCCESSOR REPRESENTATIVES.

                  In the event of the death or permanent disability of the
Representative, or the resignation of Representative as the representative of
the Opmaxx Common Stockholders hereunder, a successor Representative shall be
elected by a majority vote of the Opmaxx Common Stockholders. Each successor
Representative shall have all of the power, authority, rights and privileges
conferred by this Agreement upon the original Representative, and the term
"Representative" as used herein shall be deemed to include each successor
Representative. Unless and until the Escrow Agent receives written notice from
all of the Opmaxx Common Stockholders identifying a new representative, the
Escrow Agent shall at all times be entitled to assume that the Representative
set forth in this Agreement is the Representative hereunder. Upon receipt of
such written notice, the Escrow Agent shall be fully protected and not be held
liable for any instructions received by the new representative of the Escrow
Indemnitors.

                                                                Escrow Agreement
                                                                          Page 6
<PAGE>

                  7.3      AUTHORITY OF REPRESENTATIVE.

                  The Representative shall have full power and authority to
represent the Opmaxx Common Stockholders and their successors with respect to
all matters arising under this Agreement or related to the subject matter hereof
and all actions taken by the Representative hereunder shall be binding upon each
and all of the Opmaxx Common Stockholders and their successors, as if expressly
confirmed and ratified in writing by each of them. Without limiting the
generality of the foregoing, the Representative shall have full power and
authority to interpret all of the terms and provisions of this Agreement, to
compromise and settle any claims asserted hereunder and to authorize payments to
be made with respect hereto, on behalf of the Opmaxx Common Stockholders and
their successors. The Opmaxx Common Stockholders (with respect to the Additional
Merger Consideration) have consented to the appointment of the Representative as
representative of the Opmaxx Common Stockholders (with respect to the Additional
Merger Consideration) and as the attorney-in-fact and agent for and on behalf of
each Opmaxx Common Stockholder for the purposes of taking actions and executing
agreements and documents on behalf of any of the Opmaxx Common Stockholders as
provided in this Agreement, and, subject to the express limitations set forth
below, the taking by the Representative of any and all actions and the making of
any decisions required or permitted to be taken by him under this Agreement,
including, but not limited to, the exercise of the power to authorize delivery
to Fluence of Additional Merger Consideration and to take all actions necessary
in the judgment of the Representative for the accomplishment of the foregoing
and all of the other terms, conditions and limitations of this Agreement. The
Representative will have unlimited authority and power to act on behalf of each
Opmaxx Common Stockholder with respect to this Agreement and the disposition,
settlement or other handling of all claims, rights or obligations arising under
this Agreement with respect to Additional Merger Consideration so long as all
Opmaxx Common Stockholders are treated in the same manner (unless the Opmaxx
Common Stockholders otherwise consent). The Opmaxx Common Stockholders will be
bound by all actions taken by the Representative in connection with this
Agreement, and Fluence will be entitled to rely on any action or decision of the
Representative.

                  8.       LIMITATION OF ESCROW AGENT'S RESPONSIBILITY AND
                           LIABILITY.

                  8.1      LIMITATION OF RESPONSIBILITY.

                  The Escrow Agent's duties are limited to those set forth in
this Agreement, and the Escrow Agent, acting as such under this Agreement, is
not charged with knowledge of or any duties or responsibilities under any other
document or agreement, including, without limitations the Plan. The Escrow Agent
may execute any of its powers or responsibilities hereinafter and exercise any
rights hereunder either directly or by or through its agents or attorneys.
Nothing in this Escrow Agreement will be deemed to impose upon the Escrow Agent
any duty to qualify to do business or to act as a fiduciary or otherwise in any
jurisdiction. The Escrow Agent will not be responsible for, and will not be
under a duty to examine into or pass upon, the validity, binding effect,
execution or sufficiency of this Escrow Agreement or of any agreement mandatory
or supplemental hereto.

                                                                Escrow Agreement
                                                                          Page 7
<PAGE>

                  8.2      LIMITATION OF LIABILITY.

                  The Escrow Agent will incur no liability with respect to any
action taken, not taken or suffered by it in reliance upon any notice,
direction, instruction, consent, statement or other document believed by it to
be genuine and duly authorized, nor for any other action or inaction, except its
own willful misconduct or gross negligence. In all questions arising under this
Agreement, the Escrow Agent may rely on the advice of counsel, and for anything
done, omitted or suffered in good faith by the Escrow Agent based on such
advice, the Escrow Agent will not be liable to anyone. The Escrow Agent will not
be required to take any action hereunder involving any expense unless the
payment of such expense is made or provided for in a manner satisfactory to it.
The Escrow Agent will not be liable for any action taken or omitted to be taken
by it in good faith unless a court of competent jurisdiction determines that the
Escrow Agent's willful misconduct or gross negligence was the cause of any loss
to Fluence, the Representative, or any Opmaxx Common Stockholder. The Escrow
Agent will have no obligations with respect to the investment of Additional
Merger Consideration except as expressly provided in Section 3.1. Any dispute
which may arise with respect to the payment or ownership or right of possession
of all or any part of the Escrow or the Additional Merger Consideration, or the
duties of the Escrow Agent hereunder, shall be satisfied pursuant to the
provisions of Section 4. The Escrow Agent shall be under no duty to institute or
defend any proceeding unless the subject of such proceeding is part of its
duties hereunder. In the event of any dispute between the parties to this Escrow
Agreement, or between any of them and any other person, resulting in adverse
claims or demands being made upon any of the Additional Merger Consideration, or
in the event that Escrow Agent, in good faith, is in doubt as to what action it
should take hereunder, the Escrow Agent may, at its option, file a suit as
interpleader in a court of appropriate jurisdiction, or refuse to comply with
any claims or demands on it, or refuse to take any other action hereunder, so
long as such dispute shall continue or such doubt shall exist. The Escrow Agent
shall be entitled to continue so to refrain from acting until (i) the rights of
all parties have been fully and finally adjudicated by a court of appropriate
jurisdiction or (ii) all differences and doubt shall have been resolved by
agreement among all of the interested persons, and the Escrow Agent shall have
been notified thereof in writing signed by all such persons. The rights of the
Escrow Agent under this Section 8 are cumulative of all other rights which it
may have by law or otherwise.

                  8.3      INDEMNITY.

                  Fluence and the Opmaxx Common Stockholders (collectively, the
"Indemnifying Parties"; individually, an "Indemnifying Party") hereby jointly
and severally covenant and agree to reimburse, indemnify and hold harmless the
Escrow Agent and its employees and agents from and against any loss, damage or
liability suffered or incurred by or asserted against the Escrow Agent
(including amounts paid in settlement of any action, suit, proceeding, or claim
brought or threatened to be brought and including reasonable expenses of legal
counsel) arising out of, in connection with or based upon any act or omission by
the Escrow Agent relating in any way to this Agreement or the Escrow Agent's
services hereunder. This indemnity will not apply to any such loss, damage or
liability arising from the gross negligence or willful misconduct on the Escrow
Agent's part. Anything in this Agreement to the contrary notwithstanding, in no
event will the Escrow Agent be liable for special, indirect or consequential
damage or loss of any kind whatsoever (including but not limited to lost
profits), even if the Escrow Agent has been advised of the likelihood of such
loss or damage and regardless of the form of action.


                                                                Escrow Agreement
                                                                          Page 8
<PAGE>


                  8.4      PARTICIPATION IN DEFENSE OF THE ESCROW AGENT.

                  Each Indemnifying Party may participate at its own expense in
the defense of any claim or action that may be asserted against the Escrow
Agent, and if the Indemnifying Parties so elect, the Indemnifying Parties may
assume the defense of such claim or action; provided, however, that if there
exists a conflict of interest that would make it inappropriate for the same
counsel to represent both the Escrow Agent and the Indemnifying Parties, the
Escrow Agent's retention of separate counsel will be reimbursable as provided in
Section 8.3. The Escrow Agent's right to indemnification hereunder will survive
the Escrow Agent's resignation or removal as escrow agent hereunder and will
survive the termination of this Agreement by lapse of time or otherwise.

                  8.5      NOTICE OF CLAIMS AGAINST ESCROW AGENT.

                  The Escrow Agent will notify each Indemnifying Party by
letter, or by telephone or telecopy confirmed by letter sent U.S. first class
mail, registered or certified, of any receipt by the Escrow Agent of a written
assertion of a claim against the Escrow Agent related to this Agreement, or any
action commenced against the Escrow Agent, within ten (10) business days after
the Escrow Agent's receipt of written notice of such claim. However, the Escrow
Agent's failure to so notify each Indemnifying Party will not operate in any
manner whatsoever to relieve an Indemnifying Party from any liability it may
have otherwise on account of this Section 8. In the event the Escrow Agent fails
to so notify each Indemnifying Party and an Indemnifying Party is prejudiced
thereby, then such Indemnifying Party will not have liability to Escrow Agent
under this Section 8.

                  9.       SUCCESSOR ESCROW AGENT.

                  In the event the Escrow Agent becomes unavailable or unwilling
to continue in its capacity herewith, the Escrow Agent may resign at any time
and be discharged from its duties or obligations hereunder by giving a written
resignation to the parties to this Escrow Agreement, specifying not less than
thirty (30) days prior written notice of the date when such resignation shall
take effect; provided, however, that no such resignation shall become effective
until the appointment of a successor Escrow Agent and acceptance of such
appointment by such successor Escrow Agent. Fluence may appoint a successor
Escrow Agent without the consent of the Representative so long as such successor
is a bank with assets of at least Fifty Million Dollars ($50,000,000) which has
no direct depository or lending relationship with Fluence and which is qualified
to do business in the State of Oregon, and may appoint any other successor
Escrow Agent with the consent of the Representative, which shall not be
unreasonably withheld. If, within such notice period, Fluence provides to the
Escrow Agent written instructions with respect to the appointment of a successor
Escrow Agent in accordance with this Section 9 and directions for the transfer
of any Additional Merger Consideration then held by the Escrow Agent to such
successor, the Escrow Agent shall act in accordance with such instructions and
promptly transfer such Additional Merger Consideration to such designated
successor. If no successor Escrow Agent is appointed within sixty (60) days of
the date specified for the Escrow Agent's resignation

                                                                Escrow Agreement
                                                                          Page 9
<PAGE>


to take effect, the Escrow Agent shall have the right to apply to a court of
competent jurisdiction for such appointment at the expense of Fluence. Each
successor Escrow Agent shall execute and deliver an instrument accepting such
appointment and shall, without further acts, be vested in all the estates,
properties, rights, powers and duties of the Escrow Agent or any other
predecessor Escrow Agent as if originally named as Escrow Agent hereunder.

                  10.      TERMINATION.

                  This Agreement shall terminate upon the later of (a) the
Termination Date, or (b) the release by the Escrow Agent of all of the
Additional Merger Consideration in accordance with this Agreement.
Notwithstanding any termination of this Escrow Agreement, the provisions of
Sections 6.1, 7.1, and 8.3 hereof shall survive such termination and remain in
full force and effect.

                  11.      NOTICES.

                  All notices, requests, consents, and other communications
hereunder shall be in writing and shall be deemed to have been properly given or

                  12.      MISCELLANEOUS.

                  12.1     GOVERNING LAW; ASSIGNS.

                  This Agreement will be governed by and construed in accordance
with the internal laws of the State of Oregon without regard to conflict of law
principles and will be binding upon, and inure to the benefit of, the parties
hereto and their respective successors and permitted assigns.

                  12.2     COUNTERPARTS.

                  This Agreement may be executed in two or more counterparts,
each of which will be deemed an original, but all of which together will
constitute one and the same instrument.

                  12.3     ENTIRE AGREEMENT; SEVERABILITY.

                  Except as otherwise set forth in the Plan, this Agreement
constitutes the entire understanding and agreement of the parties with respect
to the subject matter of this Agreement and supersedes all prior agreements or
understandings, written or oral, between the parties with respect to the subject
matter hereof. If any provision of this Agreement is held to be illegal or
unenforceable by a tribunal of competent jurisdiction, then such provision shall
not be voided,

                                                                Escrow Agreement
                                                                         Page 11
<PAGE>

but shall be deemed modified to the extent necessary to make such provision
lawful and enforceable, and the other provisions of this Agreement shall remain
in full force and effect.

                  12.4     WAIVERS.

                  No waiver by any party hereto of any condition or of any
breach of any provision of this Agreement will be effective unless in writing.
No waiver by any party of any such condition or breach, in any one instance,
will be deemed to be a further or continuing waiver of any such condition or
breach or a waiver of any other condition or breach of any other provision
contained herein.

                  12.5     AMENDMENT.

                  This Agreement may be amended by the written agreement of
Fluence, the Escrow Agent and the Representative, provided that, if the Escrow
Agent does not agree to an amendment agreed upon by Fluence and the
Representative, the Escrow Agent will resign (which resignation shall be
effective immediately and, in any event, prior to the effective date of the
amendment) and Fluence will appoint a successor Escrow Agent in accordance with
Section 9 hereof. No such amendment may treat any one Opmaxx Common Stockholder
differently from the other Opmaxx Common Stockholders unless consented to in
writing by Opmaxx Common Stockholders having beneficial ownership in a majority
of the outstanding Additional Merger Consideration, as well as the consent of
any Opmaxx Common Stockholder who is to be treated differently.

IN WITNESS WHEREOF, the parties have duly executed this Agreement as of the day
and year first above written.
