escrows or similar arrangements. If, as disclosed in Section 3.9(i) of the

Third Party Technology") is Year 2000 Compliant. The Company's business,
financial condition and results of operations will not be materially adversely
affected by Year 2000 Compliance related issues. The term "Year 2000 Compliant"

Technology records, stores, processes, calculates and presents calendar dates on
or before any Millennial Date, and (ii) the Millennial Dates will not adversely
affect the operation of such Company Technology, and to the Company's Knowledge,
such Incorporated Third Party Technology, with respect to date-dependent data or

                  6.2 Post-Closing Covenants of the Parties.

                      (a) Directors of Quentra. From and after the Closing
(i)(A) so long as Enterprises and/or its Affiliates collectively beneficially
owns (within the meaning of Rule 13d-3 under the Exchange Act) ("Beneficially
Owns") a number of shares of Quentra Common Stock equal to or greater than fifty
percent (50%) of the number of shares of Series C Preferred Stock issued to
Enterprises at the Closing (subject to adjustment in the event of stock splits,
stock dividends and other similar events), Enterprises shall be entitled to
designate for nomination by the Board of Directors of Quentra, and the Board of
Directors of Quentra shall so nominate for election by Quentra's stockholders,
two directors (in accordance with Section 6.2 of this Agreement), (B) so long as
Enterprises and/or its Affiliates collectively Beneficially Own a number of
shares of Quentra Common Stock equal to or greater than twenty five percent
(25%) but less than fifty percent (50%) of the number of shares of Series C
Preferred Stock issued to Enterprises at the Closing (subject to adjustment in
the event of stock splits, stock dividends and other similar events),
Enterprises shall be entitled to designate for nomination by the Board of
Directors of Quentra, and the Board of Directors of Quentra shall so nominate
for election by Quentra's stockholders, one director and (ii) so long as Conrad
Beneficially Owns a number of shares of Quentra Common Stock equal to or greater
than thirty three percent (33%) of the number of shares of Quentra Common Stock
issued to Conrad at the Closing (subject to adjustment in the event of stock
splits, stock dividends and other similar events), Conrad shall be entitled to
designate for nomination by the Board of Directors of Quentra, and the Board of
Directors of Quentra shall so nominate for election by Quentra's stockholders,
one director. The rights of each Shareholder under this Section 6.2(a) are
freely transferable to any Person to whom or to which all of the shares of
Series C Preferred Stock and Quentra Common Stock then Beneficially Owned by
such Shareholder and its Affiliates are transferred; provided, however, that in
the case of a transfer of all of the shares of Series C Preferred Stock and
Quentra Common Stock Beneficially Owned by a Shareholder and its Affiliates, the
rights of such Shareholder under this Section 6.2(a) shall not be transferable
to such transferee unless such transferee is first approved by Quentra, such
approval not to be unreasonably withheld, conditioned or delayed; and provided,
further, that a transfer by a Shareholder (or any of its Affiliates) of shares
of Series C Preferred Stock and Quentra Common Stock and the rights of that
Shareholder under this Section 6.2(a) to the other Shareholder (or any of its
Affiliates) shall not require the prior approval of Quentra. Any disputes
between a Shareholder and Quentra pursuant to the preceding sentence shall be
resolved in accordance with the provisions of Section 10.2. So long as a
Shareholder has rights to designate a director under this Section 6.2(a), that
Shareholder shall be entitled to designate a successor to the director or
directors designated by him or it in the case of any vacancy resulting from the
death, resignation or removal of such designee prior to the expiration of his or
her term. For so long as either Shareholder has the right to designate one or
more directors for nomination pursuant to this Section 6.2(a), Quentra shall
take all actions necessary to maintain the number of directors at seven (7) and
shall not expand the Board of Directors or otherwise take any action to increase
the number of directors to a


                                       39
<PAGE>   44

number greater than seven (7), in each case without the prior written consent of
each Shareholder. Within thirty (30) days after the date that Enterprises or
Conrad loses the right to designate for nomination a director or directors to
the Board of Directors of Quentra as set forth in this Section 6.2(a),
Enterprises or Conrad, as the case may be, shall cause that number of directors
that it no longer has the right to designate to resign from the Board of
Directors of Quentra and the remaining directors shall appoint a new director or
directors to fill the vacancy created by such resignation(s). From and after the
Closing, Quentra shall indemnify each director designated pursuant to this
Section 6.2(a) (collectively, the "Shareholder Designees") to the fullest extent
permitted by applicable Law with respect to any and all liabilities arising from
or related to acts or omissions arising out of such individuals' services as
directors of Quentra. Without limiting the foregoing, if any Shareholder
Designee is or becomes involved in any capacity in any action, proceeding or
investigation in connection with any matter, including the transactions
contemplated by this Agreement, occurring on or after the Closing, Quentra shall
pay as incurred such Shareholder Designee's reasonable legal and other expenses
(including the cost of any investigation and preparation) incurred in connection
therewith in the same manner as the directors of Quentra that are not
Shareholder Designee's. From and after the Closing, Quentra shall maintain in
effect directors' and officers' liability insurance in favor of the Shareholder
Designees.

                      (b) Voting Agreements. From and after the Closing and for
so long as either Shareholder has the right to designate a director pursuant to
Section 6.2(a), Quentra shall use its best efforts to cause each person who
becomes a director of Quentra (other than any Shareholder Designee) to execute a
Voting Agreement.

                      (c) Strategic Relationships. After the Closing and until
the fourth anniversary of the Closing Date, Enterprises shall use its
commercially reasonable efforts to cause the utilities and non-regulated
businesses with which it is affiliated, and those with which it is not
affiliated but with which it has relationships, to participate in the rolling
out of the Surviving Corporation's services as such services exist on the
Closing Date.

                      (d) Additional Compensation. After the Effective Time, and
for a period of four (4)years from the Closing Date, Quentra shall issue to the
Shareholders, collectively (and for allocation between the Shareholders $7.00 to
Conrad and $3.00 to Enterprises), $10.00 for every customer obtained by the
Surviving Corporation (or any Affiliate thereof) following the Closing (the
"Customer Payment"); provided, however, that each such customer shall be subject
to the prior approval of Quentra (which approval shall not be unreasonably
withheld, conditioned or delayed) and provided, further, that each such customer
shall purchase merchandise and/or services through the Surviving Corporation's
electronic commerce systems with an aggregate retail price of $100 or more
during any continuous thirty (30) month period before the Customer Payment shall
be made under this Section 26.2(d) with respect to that customer. For purposes
of this Section 6.2, a "customer" includes, but is not limited to, a subscriber
to the Surviving Corporation's electronic commerce system (whether or not such
customer is then a customer or prospect of the Surviving Corporation,
Enterprises or the current or future Affiliates of Enterprises). Customer
Payments pursuant to this Section 6.2(d) shall be made to the Shareholders on a
quarterly basis, in arrears, and not later than the tenth Business Day after the
end of each calendar quarter. Notwithstanding the foregoing, no


                                       40
<PAGE>   45

Customer Payment shall be made (i) for any customer obtained on or after the
four (4) year anniversary of the Closing Date, or (ii) for any customers in
excess of 5.6 million customers.

                      (e) Registration of Registrable Securities.

                          (i) Within 120 days after the Closing Date, Quentra
shall file with the SEC a shelf registration statement under Rule 415 of the
Securities Act on Form S-1 (or any successor form thereto) covering the sale or
other distribution of all of the Registrable Securities, and shall keep such
shelf registration statement effective until all Registrable Securities have
been sold. If such shelf registration statement is not filed within 120 days
after the Closing Date, or if such shelf registration statement is not declared
effective by the SEC before the first anniversary of the Closing Date, then
Quentra shall pay to each Shareholder on the fifth Business Day following such
first anniversary of the Closing Date cash in an amount equal to (x) such number
of additional shares of Quentra Common Stock as is equal to twelve percent (12%)
of the aggregate number of Registrable Securities held by such Shareholder on
such first anniversary of the Closing Date multiplied by (y) the average closing
sales price of the Quentra Common Stock for the five (5) Business Days
immediately preceding the date such registration statement should have been
filed or declared effective, as applicable, up to a maximum price of $6.00 per
share) (the "Liquidation Payment"). Quentra shall amend the shelf registration
statement from time to time at the request of either Shareholder to include in
such registration statement Registrable Securities issued to such Shareholder
subsequent to the filing of the registration statement (or any amendment
thereto) with the SEC. Quentra shall notify each Shareholder promptly (A) when
the shelf registration statement or any amendment or supplement thereto has been
filed and when the same (as amended or supplemented, as the case may be) has
become effective, (B) of the issuance by the SEC or any state securities
authority of any stop order suspending the effectiveness of such registration
statement or the initiation of any proceedings for that purpose, (C) of the
receipt by Quentra of any notification with respect to the suspension of the
qualification of the Registrable Securities for sale in any jurisdiction or the
initiation or threatening of any proceeding for such purpose and (D) of the
happening of any event or the discovery of any facts that makes any statement
made in the registration statement, the prospectus constituting a part thereof
or any document incorporated therein by reference untrue in any material respect
or that requires the making of any changes in the registration statement, the
prospectus constituting a part thereof or any document incorporated therein by
reference in order to make the statements therein not contain an untrue
statement of a material fact or omit to state any material fact necessary to
make the statements therein not misleading. Quentra shall make every effort to
obtain the withdrawal of any order suspending the effectiveness of such
registration statement at the earliest possible time. Quentra shall timely file
all reports required to be filed by it under Section 13 or Section 15(d) of the
Exchange Act. The payment of the Liquidation Payment shall not constitute a
waiver of Shareholders' right to seek specific performance of this Section
6.2(e). The parties hereto acknowledge that the Liquidation Payment is not a
penalty, but constitutes liquidated damages.

                          (ii) The Shareholders agree that no Shareholder may
participate in or have its shares of Quentra Common Stock included in any such
shelf registration statement unless such Shareholder completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms


                                       41
<PAGE>   46

of such underwriting arrangements or to ensure compliance with the requirements
of the Securities Act.

                          (iii) In addition to the information required to be
provided in a notice and questionnaire by each Shareholder to Quentra, Quentra
may require each Shareholder to furnish to Quentra such additional information
regarding each Shareholder and such Shareholder's intended method of
distribution of the Quentra Common Stock as Quentra may from time to time
reasonably request in writing, but only to the extent that such information is
required in order to comply with the Securities Act. Each Shareholder agrees to
notify Quentra as promptly as practicable of any inaccuracy or change in
information previously furnished by such Shareholder to Quentra or of the
occurrence of any event in either case as a result of which any prospectus
relating to such registration contains or would contain an untrue statement of a
material fact regarding such Shareholder or such Shareholder's intended method
of disposition of the Quentra Common Stock or omits to state any material fact
regarding such Shareholder or such Shareholder's intended method of disposition
of the Quentra Common Stock required to be stated therein or necessary to make
statements therein not misleading in light of the circumstances then existing,
and promptly to furnish to Quentra any additional information required to
correct and update any previously furnished information or required so that such
prospectus shall not contain, with respect to such Shareholder or the
disposition of the applicable Quentra Common Stock an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances then existing.

                      (f) Future Agreements. Quentra shall not enter into any
contract, agreement or other instrument, whether or not written, or any
amendment thereto, which in any way materially adversely affects any right or
rights of the Shareholders or any of them hereunder, including without
limitation the rights of the Shareholders set forth under paragraph (a) of this
Section 6.2, without the express prior written consent of the Shareholders.

                  6.3 Expenses. Whether or not the Merger is consummated, all
Expenses incurred in connection with this Agreement and the Merger and the other
transactions contemplated hereby shall be paid by the Party incurring such
Expense; provided, however, that the expenses incurred by the Company shall be
paid by the Shareholders. For purposes of this Agreement, "Expenses" consist of
all out-of-pocket expenses (including, all reasonable fees and expenses of
counsel, accountants, investment bankers, experts and consultants to a Party
hereto and its Affiliates) incurred by a Party or on its behalf in connection
with or related to the authorization, preparation, negotiation, execution and
performance of this Agreement, and all other matters related to the closing of
the transactions contemplated hereby.

                  6.4 Lock-Up Agreement. None of (i) James R. McCullough, (ii)
KRJ, LLC or (iii) First Venture Leasing shall directly or indirectly sell,
dispose of, encumber, pledge, hypothecate or otherwise transfer (a "Transfer")
any shares of the capital stock of Quentra (or any securities convertible into
or exchangeable for shares of the capital stock of Quentra); except in
connection with (A) the sale or merger of Quentra in a single transaction or a
series of related transactions (excluding the transaction contemplated at the
Closing), or (B) a tender offer pursuant to Regulation 13D-G, Regulation 14D or
Regulation 14E of the Exchange Act or until the later of (x) nine (9) months
after the Closing or (y) ninety (90) days after the effective date of


                                       42

the shelf registration statement referred to in Section 6.2(e) of this
Agreement, but in no event longer than the first anniversary of the Closing
Date.

<PAGE>   49

representations and warranties or the breach of any of its covenants or
agreements set forth in this Agreement.

                                    ARTICLE 9

                            SURVIVAL; INDEMNIFICATION

                  9.1 Survival. All representations and warranties set forth
herein shall survive the Closing, but no claim may be made with respect to any
breach of any representation or warranty hereunder after the twenty-fourth
(24th) month anniversary of the Closing Date; provided, however, that the
representations and warranties contained in Sections 3.1, 4.1, 4.2, 5.3 and 5.5
shall survive without limitation as to time. The agreements and covenants of the
Parties set forth in Sections 6.3 and 6.6 and Article 9 of this Agreement shall

                  9.2 Indemnification by the Shareholders.

                      (a) By Enterprises. Subject to Section 9.6 below,
Enterprises shall severally indemnify, defend, save and hold Quentra and its
officers, directors, employees, Affiliates and agents (including, after the
Closing, the Surviving Corporation) (collectively, "Quentra Indemnitees")
harmless from and against all demands, claims, actions or causes of action,
assessments, losses, damages, deficiencies, liabilities, costs and expenses,
including reasonable attorneys' fees (collectively, "Quentra Damages") asserted
against, imposed upon, resulting to or incurred by any of the Quentra
Indemnitees, directly or indirectly, in connection with, or arising out of, or
resulting from (i) a breach of any of the representations and warranties made by
Enterprises in this Agreement, but only if a claim with respect thereto is made
within the time limits, if any, prescribed by the first sentence of Section 9.1
or (ii) a breach of any of the covenants or agreements made by Enterprises in or
pursuant to this Agreement and in any Transaction Document to which Enterprises
is a party.

                      (b) By Conrad and Employee. Subject to Section 9.6 below,
Employee and Conrad shall jointly and severally indemnify, defend, save and hold

Indemnitees, directly or indirectly, in connection with, or arising out of, or
resulting from (i) a breach of any of the representations and warranties


                                       45
<PAGE>   50

made by the Company, Employee or Conrad in this Agreement, but only if a claim
with respect thereto is made within the time limits, if any, prescribed by the
first sentence of Section 9.1, (ii) a breach of any of the covenants or
agreements made by the Company, Employee or Conrad in or pursuant to this
Agreement and in any Transaction Document to which the Company, Employee or
Conrad is a party, (iii) the Memorandum of Understanding between SMI and PBNV
executed on July 30, 1999, or (iv) a breach of the covenants and agreements set
forth in the nondisclosure agreements transferred to the Company pursuant to the
terms of the Assignment and Assumption Agreement dated May 1, 2000 between the
Company and HomeAccess MicroWeb, LLC, which occur prior to the Closing Date, or
any other liabilities incurred by the Quentra Indemnitees under such agreements
after the Closing Date, which liabilities are not the result of or caused by the
actions or inaction of the Quentra Indemnitees; provided, however, that Conrad
and her Affiliates, other than Employee, shall not be required to indemnify the
Quentra Indemnitees under the Promissory Note and the Personal Services
Agreement except to the extent set forth in the Pledge Agreement.

                  9.3 Indemnification by Quentra. Subject to Section 9.6 below,
Quentra shall indemnify, defend, save and hold each Shareholder and their
respective officers, directors, employees, Affiliates and agents (collectively,
"Shareholder Indemnitees") harmless from and against any and all demands,
claims, actions or causes of action, assessments, losses, damages, deficiencies,
liabilities, costs and expenses, including reasonable attorneys' fees
(collectively, "Shareholder Damages") asserted against, imposed upon, resulting
to or incurred by any of the Shareholder Indemnitees, directly or indirectly, in
connection with, or arising out of, or resulting from, (i) a breach of any of
the representations and warranties made by Quentra in this Agreement, but only
if a claim with respect thereto is made within the time limits, if any,
prescribed by the first sentence of Section 9.1 or (ii) a breach of any of the
covenants or agreements made by Quentra in or pursuant to this Agreement and in
any Transaction Document to which Quentra is a party.

                  9.4 Notice of Claims. If any Quentra Indemnitee or Shareholder
Indemnitee (an "Indemnified Party") believes that it has suffered or incurred or
will suffer or incur any Quentra Damages or Shareholder Damages ("Damages") for
which it is entitled to indemnification under this Article 9, or if any legal,
governmental or administrative proceeding which may result in such damages is
threatened or asserted, such Indemnified Party shall so notify the party or
parties from whom indemnification is being claimed (the "Indemnifying Party")
with reasonable promptness and reasonable particularity in light of the
circumstances then existing. If any action at law or suit in equity is
instituted by or against a third party with respect to which any Indemnified
Party intends to claim any Damages, such Indemnified Party shall promptly notify
the Indemnifying Party of such action or suit. The failure of an Indemnified
Party to give any notice required by this Section 9.4 shall not affect any of
such party's rights under this Article 9 except to the extent such failure is
actually prejudicial to the rights or obligations of the Indemnifying Party.

                  9.5 Third Party Claims. In case any legal, governmental or
administrative proceeding which may result in such Damages is instituted,
threatened or asserted by or against a third party with respect to which an
Indemnified Party intends to claim any Damages and the Indemnified Party
notifies the Indemnifying Party of such proceeding as provided in Section 9.4,
the Indemnifying Party shall be entitled to participate therein and, to the
extent that it may wish,


                                       46
<PAGE>   51

jointly with any other Indemnifying Party similarly notified, to assume the
defense thereof, with counsel satisfactory to such Indemnified Party (who may be
counsel to the Indemnifying Party), and after notice from the Indemnifying Party
to such Indemnified Party of its election so to assume the defense thereof, the
Indemnifying Party will not be liable to such Indemnified Party under this
Article 9 for any legal or other expenses subsequently incurred by such
Indemnified Party in connection with the defense thereof. No Indemnifying Party
shall, without the prior written consent of the Indemnified Party, effect any
settlement of any pending or threatened action in respect of which any
Indemnified Party is or could have been a party and indemnity could have been
sought hereunder by such Indemnified Party unless such settlement includes an
unconditional release of such Indemnified Party from all liability on any claims
that are the subject matter of such proceeding.

                  9.6 Limitation on Damages. Notwithstanding any provision under
this Article 9 to the contrary, no Party shall have any indemnity liability with
respect to a breach of any of the representations and warranties made by that
Party in this Agreement until the aggregate amount of Damages incurred by the
other Party with respect to such breaches by the first Party exceeds the sum of
$50,000, but if the aggregate amount of such Damages exceeds $50,000,
indemnification shall be made to the full extent of Damages; provided, however,
that, the foregoing limitations shall not apply to any matter relating to title
to the Company Common Stock, the Company Preferred Stock, the Series C Preferred
Stock or the Quentra Common Stock. In no event shall the liability of
Enterprises under this Article 9 exceed One Million Two Hundred Seventy Five
Thousand Dollars ($1,275,000) and in no event shall the liability of Conrad and
Employee under this Article 9 exceed Two Million Nine Hundred Seventy Five
Thousand Dollars ($2,975,000) in the aggregate; provided, however, that the
limitations on the liability of any Indemnifying Party set forth in this Article
9 shall not apply, and no other remedy at law or in equity that an Indemnified
Party may have against an Indemnifying Party but for the provisions of this
Article 9 shall be limited or restricted, in the event of such Indemnifying
Party's actual fraud; and provided, further, that any claims by Enterprises
arising out of or related to its purchase of securities from the Company shall
be made solely against Conrad and Employee and not the Company or Quentra. All
Damages payable hereunder shall be paid promptly in cash. The Parties
acknowledge and agree that the provisions of this Article 9 shall be the sole
and exclusive remedy of any Party for any and all breaches of the
representations and warranties of any other Party or the failure of any other
Party to perform any covenant or other agreement set forth in this Agreement;
provided, however, that the foregoing shall not constitute a waiver of any
Party's right to seek specific performance of any provisions of this Agreement.

                  9.8 No Circular Recovery. No Shareholder will be entitled to
make any claim for indemnification against the Surviving Corporation or any of
its Affiliates by reason of the fact that such Shareholder (or any of his, her
or its officers, directors, agents or other representatives) was a controlling
person, director, officer, employee, agent or other representative of the
Company or of any of its Affiliates or was serving as such for another Person at
the request of the Company or any of its shareholders or Affiliates (whether
such claim is for losses of any kind or otherwise and whether such claim is
pursuant to any statute, charter, by-law, contractual obligation or otherwise)
with respect to any action brought by Quentra or the Surviving Corporation
against such Shareholder or the Shareholders generally (whether such action is
pursuant to this Agreement, applicable law, or otherwise).

                                  MISCELLANEOUS

                  10.1 Representations. Each Party agrees that, except for the
representations and warranties contained in this Agreement, no Party has made
any other representations and warranties, and each Party disclaims any other
representations and warranties, made by itself or any of its officers,
directors, employees, agents, financial and legal advisors or other
representatives with respect to the execution and delivery of this Agreement or
the transactions contemplated by this Agreement, notwithstanding the delivery of
disclosure to any other Party or any Party's representatives of any
documentation or other information with respect to any one or more of the
foregoing.

                  10.2 Dispute Resolution. Any dispute between a Shareholder and
Quentra under Section 6.2(a) shall be settled by arbitration in accordance with
the Commercial Arbitration Rules of the American Arbitration Association in Los
Angeles, California. The arbitration proceeding shall be conducted by one
arbitrator selected in accordance with the Commercial Arbitration Rules of the
American Arbitration Association. The arbitration shall be conducted in
accordance with the following procedures and time schedules unless otherwise
mutually agreed to by such Shareholder and Quentra: (i) within ten (10) days
after the appointment of the arbitrator, such Shareholder and Quentra shall
provide the arbitrator with all documents, records and supporting information
reasonably necessary to resolve the dispute and a hearing on such dispute shall
be held; (ii) within three (3) days after the hearing, the arbitrator shall
render his or her decision; (iii) such Shareholder and Quentra shall each be
entitled to present the testimony of up to two (2) individuals, which testimony
shall not exceed four (4) hours in the aggregate; and (iv) no discovery shall be
allowed. The decision or award of the arbitrator shall be final and binding upon
such Shareholder and Quentra to same extent and to the same degree as if the
matter had been adjudicated by a court of competent jurisdiction and shall be
enforceable under the Federal Arbitrations Act. The costs and expenses of the
arbitration and of the prevailing party (including reasonable attorneys' fees)
shall be paid by the non-prevailing party.

                  10.3 Waiver. Except as expressly provided in this Agreement,
neither the failure nor any delay on the part of any Party in exercising any
right, power or remedy hereunder shall operate as a waiver thereof, or of any
other right, power or remedy; nor shall any single or partial exercise of any
right, power or remedy preclude any further or other exercise thereof, or the
exercise of any other right, power or remedy. Except as expressly provided
herein, no waiver of any of the provisions of this Agreement shall be valid
unless it is in writing and signed by the Party against whom the waiver is
sought to be enforced.

                  10.4 Assignment. This Agreement (and all rights hereunder)
shall be binding on and inure to the benefit of the Parties hereto and their
successors and assigns.

                  10.5 Notices. Any and all notices or other communications
required or permitted under this Agreement shall be given in writing and
delivered in Person or sent by United States certified or registered mail,
postage prepaid, return receipt requested, or by overnight express mail, or by
telex, facsimile or telecopy to the address of such party set forth

                  Any Party may, by notice so delivered, change its address for
notice purposes hereunder.

                  10.6 Further Assurances. After the Closing each Party hereto
at the reasonable request of the other Party hereto and without additional
consideration, shall execute and deliver, or shall cause to be executed and
delivered, from time to time, such further certificates, agreements or
instruments of conveyance and transfer, assumption, release and acquittance and
shall take such other action as the other Party hereto may reasonably request,
to consummate or implement the transactions contemplated by this Agreement.

                  10.7 Severability. If any provision of this Agreement is
invalid, illegal or unenforceable, the balance of this Agreement shall remain in
full force and effect and this Agreement shall be construed in all respects as
if such invalid, illegal or unenforceable provision were omitted. If any
provision is inapplicable to any Person or circumstance, it shall, nevertheless,
remain applicable to all other Persons and circumstances.

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

                  10.9 Construction. Any section headings in this Agreement are
for convenience of reference only, and shall be given no effect in the
construction or interpretation of this Agreement or any provisions thereof. No
provision of this Agreement will be interpreted in favor of, or against, any
Party by reason of the extent to which any such Party or its counsel
participated in the doing thereof or by reason of the extent to which any such
provision is inconsistent with any prior draft hereof or thereof.

                  10.10 Entire Agreement; Amendment. This Agreement, the
exhibits hereto, each of which is deemed to be a part hereof, and any other
agreements, instruments or documents executed and delivered by the Parties (or
their Subsidiaries) pursuant to the express terms of this Agreement, constitute
the entire agreement and understanding between the Parties, and it is understood
and agreed that all previous undertakings, negotiations and agreements between
the Parties regarding the subject matter hereof are merged herein; provided,
however, that the confidentiality agreement entered into between the Company and
Quentra shall remain in full force and effect. Without limitation of the
foregoing, (i) the Letter of Intent dated April 3, 2000, as amended by the
letter agreement dated April 27, 2000, and (ii) the Existing Agreement is hereby
terminated of no further force or effect. This Agreement may not be modified
orally, but only by an agreement in writing signed by each of the Parties.

                  10.11 No Third Party Beneficiaries. Nothing in this Agreement
shall provide any benefit to any third party or entitle any third party to any
claim, cause of action, remedy or right of any kind, it being the intent of the
Parties that this Agreement shall not be construed as a third party beneficiary
contract.

                  10.12 Public Announcements. Quentra and the Company shall
consult with each other before issuing any press release with respect to the
Merger or this Agreement and shall not issue any such press release or make any
such public statement until the content thereof has been approved by the other
party, which approval shall not be unreasonably withheld; provided, however,
that a party may, without the prior consent of the other party, issue such press
release or make such public statement as may upon the advice of counsel be
required by law or the Nasdaq National Market if it has used reasonable efforts
to consult with the other party. Each of Quentra and the Company shall make all
necessary filings with Governmental Authority and shall promptly provide the
other party with copies of filings made by such party between the date hereof
and the Effective Time. Notwithstanding the foregoing, no Party shall (and each
Party shall cause its Affiliates and Associates to not) issue any press release
or make any public statement that directly or indirectly refers to (i) any other
Party or any of its respective Affiliates (by name or otherwise) without the
prior written consent of such second Party, which consent may be withheld in the
sole discretion of such second Party or (ii) the Company (by name or otherwise)
without the prior written consent of the Shareholders, which consent may be
withheld in the sole discretion of each Shareholder; provided, however, that a
Party may, without the prior written consent required above, issue such press
release or make such public statement as may upon the advice of counsel be
required by law or the Nasdaq National Market if it has used reasonable efforts
to consult with the other Party.

                  10.13 Waiver and Release. Except as specifically set forth in
this Agreement and in the agreements contemplated hereby, each of the Parties
hereby releases and forever discharges the other Parties, and their respective
directors, officers, employees, agents, successors and assigns from and against
any and all claims, demands, liabilities, obligations, damages, costs, expenses,
actions and causes of action, in law or in equity, known or unknown, which such
Party ever had, now has or may have against the other Parties as of the date
hereof, arising out of or related to the Existing Agreement.
