                           CONVERTIBLE PROMISSORY NOTE

                         (NEXTRON COMMUNICATIONS, INC.)

$5,000,000                                                     September 7, 2000

       FOR VALUE RECEIVED, the undersigned, Nextron Communications, Inc., a
California corporation (the "Maker"), does hereby unconditionally promise to pay
to Safeguard 2000 Capital, L.P., a Delaware limited partnership, or its
registered assigns (the "Holder") on September 30, 2001 (the "Maturity Date")
the principal sum of FIVE MILLION DOLLARS ($5,000,000), together with interest
thereon at the rate and payable as hereinafter set forth.

       1. Payment of Interest and Principal. Payments of principal and interest
on this promissory note (the "Note") shall be payable in accordance with the
terms hereof. Principal and interest shall be payable on the Maturity Date.
Interest on principal amount outstanding under this Note shall accrue from the
date hereof at an annual rate equal to the announced prime rate of PNC Bank,
N.A. (the "Prime Rate") plus one percent (1%). Such interest rate shall be
changed when and as the Prime Rate changes. Interest shall be calculated for
actual days elapsed on the basis of a 360-day year.

       Notwithstanding anything in this Note, the interest rate charged hereon
shall not exceed the maximum rate allowable by applicable law. If any stated
interest rate herein exceeds the maximum allowable rate, then the interest rate
shall be reduced to the maximum allowable rate, and any excess payment of
interest made by the Maker at any time shall be applied to the unpaid balance of
any outstanding principal of this Note

       2. Prepayment Limitations. The outstanding principal amount of this Note
may be prepaid by the Maker, in whole or in part, solely with the consent of the
Holder; provided, however, that if the Holder elects not to exercise its right
when it arises to convert the outstanding balance due under this Note into New
Stock (as hereinafter defined) pursuant to Paragraph 4 below, the outstanding
principal amount of this Note may thereafter be prepaid in whole at any time or
in part from time to time without any prepayment penalty or premium or the need
to obtain the consent of the Holder; provided, that upon such payment any
interest due to the date of such prepayment on such prepaid amount shall also be
paid.

\
       3. Method and Application Payments. All amounts payable hereunder shall
be paid by the Maker in lawful money of the United States of America by
certified check or wire transfer in immediately available and freely
transferable funds at the place designated by Holder in writing to Maker for
such payment. All payments made on this Note (including, without limitation,
prepayments) shall be applied, at the option of the Holder, first to late
charges and collection costs, if any, then to accrued interest, and then to
principal.

       4. Conversion. The outstanding balance due under this Note (including,
without limitation, principal and accrued interest due and unpaid hereunder)
shall automatically convert into stock of the class issued in the next round of
equity financing ("New Stock"), whether private or public, raising not less than
$5,000,000 from investors other than the Holder, at a conversion price equal to
the average price per share paid by such third party investors. Such conversion
shall be effective immediately upon the closing of the sale of such New Stock to
the third party investors. Upon any such conversion, this Note will be
surrendered to the Maker at its principal office as set forth in Paragraph 8
hereof. In addition:

              (a) the Maker shall reserve and keep available out of its
authorized but unissued stock, solely for the issuance and delivery upon the
conversion of this Note and all similar Notes, such number of its duly
authorized shares of preferred and common stock as from time to time shall be
issuable upon the conversion of this Note and all similar Notes at the time
outstanding or upon the conversion of the New Stock issued upon conversion of
any such Note, and all of such shares of stock so issuable, when issued and
delivered in accordance with the terms hereof or the terms of the New Stock,
will be duly authorized, validly issued, fully-paid and non-assessable; and

              (b) all of the provisions of Section 2 - "Registration Rights" in
the Investors' Rights Agreement dated as of November 24, 1999 between the
Company and the Purchaser (the "Investors' Rights Agreement") shall apply
equally to the shares of New Stock or the shares of common stock issuable upon
conversion of the New Stock that is issuable upon conversion of this Note or any
similar Notes, and each reference in the Investors' Rights Agreement to
"Registrable Shares" shall mean the Registrable Shares as defined in that
agreement and the shares of New Stock or common stock issuable upon conversion
of the New Stock so issuable, collectively as a single class.

If there is no financing which consists of such issuance of New Stock on or
prior to the Maturity Date, on or after the Maturity Date, this Note shall
become due and payable in cash as otherwise provided herein.

       5. Events or Default. Each of following events shall constitute an event
of default (an "Event of Default") hereunder:

              (a) If the Maker shall fail to pay when due any interest or
principal or any other sum payable to the Holder hereunder and with respect to
payments of interest only, such failure shall continue incurred for five days
after the due date thereof.

                                       2
<PAGE>   3

              (b) If the Maker shall default in the performance of any other
agreement or covenant contained herein and such default shall continue uncured
for 10 days after written notice thereof to the Maker given by the Holder (or,
if such default cannot reasonably be cured within such 10 day period and, the
Maker is proceeding to cure with reasonable diligence, such period of time as
shall be reasonably necessary to cure such default, but in no event more than
30 days).

              (c) If Maker shall become insolvent, bankrupt or shall generally
fail to pay its debts as such debts become due; or if Maker shall admit in
writing its inability to pay its debts; or if Maker shall suffer a receiver or
trustee for it or substantially all of its property to be appointed; or if Maker
makes an assignment for the benefit of creditors; or if proceedings under any
law related to bankruptcy or insolvency or the reorganization or the release of
debtors are instituted against the Maker and are not dismissed or stayed within
60 days; or if a receiver or trustee for Maker or substantially all of its
property shall be appointed without Maker's consent and such receiver or trustee
shall not be discharged within 60 days; or if proceedings relating to the Maker
under any law related to bankruptcy or insolvency or the reorganization or the
release of debtors are instituted or commenced by the Maker.

              (d) If any judgment, writ, warrant of attachment or execution or
similar process which calls for payment or presents liability in excess of
$25,000 individually, or $100,000 in the aggregate, (not covered by insurance)
shall be rendered or issued against or levied against the Maker or Maker's
property and such process shall not be paid, waived, stayed, vacated,
discharged, settled, satisfied or fully bonded within 10 days after its issuance
or levy.

              (e) If there shall occur a default by the Maker under any
document, agreement or instrument to which the Maker is a party now or hereafter
evidencing or securing any indebtedness pursuant to which the Maker has borrowed
at least $25,000, after giving effect to any applicable grace period therein.

       6. Remedies. Upon the happening of any Event of Default and at any time
thereafter, by notice by the Holder to the Maker (except if any Event of Default
described in Paragraph 5(c) shall occur in which case acceleration shall occur
automatically and without notice), the Holder may declare the entire unpaid
balance, principal and interest, of all indebtedness of the Maker to the Holder
hereunder to be immediately due and payable, even if prior to the Maturity Date.
Upon such declaration, the Holder shall have the immediate right to exercise all
rights granted hereunder and all rights and remedies granted by any applicable
law, all of which shall be cumulative in nature. In addition, upon the
occurrence of any Event of Default, interest shall automatically and without
notice begin to accrue on the outstanding balance of this Note at the Prime Rate
plus three percent (3%).

       7. Dispute Resolution. Any action, suit or proceeding where the amount in
controversy as to at least one party, exclusive of interest and costs, exceeds
$100,000 ("Summary Proceeding"), arising out of or relating to the Obligations
or the Documents (as such terms are defined in the Pledge Agreement), or the
breach, termination or validity thereof, shall be litigated

                                       3
<PAGE>   4

exclusively in the Superior Court of the State of Delaware (the "Delaware
Superior Court") as a summary proceeding pursuant to Rules 124-131 of the
Delaware Superior Court, or any successor rules (the "Summary Proceeding
Rules"). Each of the parties hereto hereby irrevocably and unconditionally (i)
submits to the jurisdiction of the Delaware Superior Court for any Summary
Proceeding, (ii) agrees not to commence any Summary Proceeding except in the
Delaware Superior Court, (iii) waives, and agrees not to plead or to make, any
objection to the venue of any Summary Proceeding in the Delaware Superior Court,
(iv) waives, and agrees not to plead or to make, any claim that any Summary
Proceeding brought in the Delaware Superior Court has been brought in an
improper or otherwise inconvenient forum, (v) waives, and agrees not to plead or
to make, any claim that the Delaware Superior Court lacks personal jurisdiction
over it, (vi) waives its right to remove any Summary Proceeding to the federal
courts except where such courts are vested with sole and exclusive jurisdiction
by statute and (vii) understands and agrees that it shall not seek a jury trial
or punitive damages in any Summary Proceeding based upon or arising out of or
otherwise related to the Obligations or the Documents and waives any and all
rights to any such jury trial or to seek punitive damages.

       In the event any action, suit or proceeding where the amount in
controversy as to at least one party, exclusive of interest and costs, does not
exceed $100,000 (a "Proceeding") arising out of or relating to the Obligations
or the Documents or the breach, termination or validity thereof is brought, the
parties to such Proceeding agree to make application to the Delaware Superior
Court to proceed under the Summary Proceeding Rules. Until such time as such
application is rejected, such Proceeding shall be treated as a Summary
Proceeding and all of the foregoing provisions relating to Summary Proceedings
shall apply to such Proceeding.

       If a Summary Proceeding is not available to resolve any dispute
hereunder, the controversy or claim shall be settled by arbitration conducted on
a confidential basis, under the U.S. Arbitration Act, if applicable, and the
then current Commercial Arbitration Rules of the American Arbitration
Association (the "Association") strictly in accordance with the terms of this
Note and the substantive law of the State of Delaware. The arbitration shall be
conducted at the Association's regional office located closest to the Holder's
principal place of business by three arbitrators, at least one of whom shall be
an attorney with substantial experience in creditor-debtor law. Judgment upon
the arbitrators' award may be entered and enforced in any court of competent
jurisdiction. Neither party shall institute a proceeding hereunder unless at
least 60 days prior thereto such party shall have given written notice to the
other party of its intent to do so.

       Neither party shall be precluded hereby from securing equitable remedies
in courts of any jurisdiction, including, but not limited to, temporary
restraining orders and preliminary injunctions to protect its rights and
interests but such shall not be sought as a means to avoid or stay arbitration
or Summary Proceedings.

       8. Miscellaneous. The Maker hereby waives presentment, demand, protest
and notice of dishonor and protest, and also waives all other exemptions; and
agrees that extension or extensions of the time of payment of this Note or any
installment or part thereof may be made before, at or after maturity by
agreement by the Holder. Upon an event of default hereunder, the

                                       4
<PAGE>   5

Holder shall have the right to offset the amount owed by the Maker against any
amounts owed by the Holder in any capacity to the Maker, whether or not due, and
the Holder shall be deemed to have exercised such right of offset and to have
made a charge against any such account or amounts immediately upon the
occurrence of an event of default hereunder even though such charge is made or
entered on the books of the Holder subsequent thereto. The Maker shall pay to
the Holder, upon demand, all costs and expenses, including, without limitation,
attorneys' fees and legal expenses, that may be incurred by the Holder in
connection with the enforcement of this Note.

       Notices required to be given hereunder shall be deemed validly given (i)
three business days after sent, postage prepaid, by certified mail, return
receipt requested, (ii) one business day after sent, charges paid by the sender,
by Federal Express Next Day Delivery or other guaranteed delivery service, (iii)
when sent by facsimile transmission, or (iv) when delivered by hand:

illegal, invalid or unenforceable for any reason whatsoever shall not affect the

                                                                   EXHIBIT 10.12

                               INDEMNITY AGREEMENT

        THIS AGREEMENT is made and entered into as of _________, 2000 by and
between Nextron Communications, Inc., a California corporation (the
"Corporation"), and ____________ ("Agent").

                                    RECITALS

        WHEREAS, Agent performs a valuable service to the Corporation in his
capacity as a director or officer of the Corporation;

        WHEREAS, the shareholders of the Corporation have adopted bylaws (the
"Bylaws") providing for the indemnification of the directors, officers,
employees and other agents of the Corporation, including persons serving at the
request of the Corporation in such capacities with other corporations or
enterprises, as authorized by the California General Corporation Law, as amended
(the "Code");

        WHEREAS, the Bylaws and the Code, by their non-exclusive nature, permit
contracts between the Corporation and its directors, officers, employees and
other agents with respect to indemnification of such persons; and

        WHEREAS, in order to induce Agent to continue to serve in the capacity
set forth above, the Corporation has determined and agreed to enter into this
Agreement with Agent;

        NOW, THEREFORE, in consideration of Agent's continued service in the
capacity set forth above after the date hereof, the parties hereto agree as
follows:

                                    AGREEMENT

        1. Service to the Corporation. Agent will serve, at the will of the
Corporation or under separate contract, if any such contract exists, as a
director, officer or agent of the Corporation or as a director, officer or other
fiduciary of an affiliate of the Corporation (including any employee benefit
plan of the Corporation) faithfully and to the best of his ability so long as he
is duly elected and qualified in accordance with the provisions of the Bylaws or
other applicable charter documents of the Corporation or such affiliate;
provided, however, that Agent may at any time and for any reason resign from
such position (subject to any contractual obligation that Agent may have assumed
apart from this Agreement) and that the Corporation or any affiliate shall have
no obligation under this Agreement to continue Agent in any such position.

        2. Maintenance of Liability Insurance.

            (a) The Corporation hereby covenants and agrees that, so long as the
Agent shall continue to serve as an agent of the Corporation and thereafter so
long as the Agent shall be

<PAGE>   2

subject to any possible action, suit or proceeding by reason of the fact that
the Agent was an agent of the Corporation, the Corporation, subject to Section
2(c), shall promptly obtain and maintain in full force and effect directors' and
officers' liability insurance ("D&O Insurance") in reasonable amounts from
established and reputable insurers.

            (b) In all policies of D&O Insurance, the Agent shall be named as an
insured in such a manner as to provide the Agent the same rights and benefits as
are accorded to the most favorably insured of the Corporation's directors, if
the Agent is a director; or of the Corporation's officers, if the Agent is not a
director of the Corporation but is an officer; or of the Corporation's key
employees, if the Agent is not an officer or director but is a key employee or
other agent.

            (c) Notwithstanding the foregoing, the Corporation shall have no
obligation to obtain or maintain D&O Insurance if the Corporation determines in
good faith that such insurance is not available at a reasonable price, the
premium costs for such insurance are disproportionate to the amount of coverage
provided, the coverage provided by such insurance is limited by exclusions so as
to provide an insufficient benefit, or the Agent is covered by similar insurance
maintained by a subsidiary of the Corporation.

        3. Indemnity of Agent. The Corporation hereby agrees to hold harmless
and indemnify Agent to the fullest extent authorized or permitted by the
provision of the Bylaws and the Code.

        4. Additional Indemnity. In addition to and not in limitation of the
indemnification otherwise provided for herein, and subject only to the
exclusions set forth in Section 5 hereof, the Corporation hereby further agrees
to hold harmless and indemnify Agent:

            (a) against any and all expenses (including attorneys' fees),
witness fees, damages, judgments, fines and amounts paid in settlement and any
other amounts that Agent becomes legally obligated to pay because of any claim
or claims made against or by him in connection with any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, arbitrational,
administrative or investigative (including an action by or in the right of the
Corporation) to which Agent is, was or at any time becomes a party, or is
threatened to be made a party, by reason of the fact that Agent is, was or at
any time becomes a director, officer, employee or other agent of the
Corporation, or is or was serving or at any time serves at the request of the
Corporation as a director, officer, employee or other agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, or was a director, officer, employee or agent of a corporation which
was a predecessor corporation of the Corporation or of another enterprise at the
request of such predecessor corporation; and

            (b) otherwise to the fullest extent as may be provided to Agent by
the Corporation under the non-exclusivity provisions of Article VI of the Bylaws
and the Code.

        5. Limitations on Additional Indemnity. No indemnity pursuant to Section
4 hereof shall be paid by the Corporation:

                                       2
<PAGE>   3

            (a) on account of any claim against Agent for an accounting of
profits made from the purchase or sale by Agent of securities of the Corporation
pursuant to the provisions of Section 16(b) of the Securities Exchange Act of
1934 and amendments thereto or similar provisions of any federal, state or local
statutory law;

            (b) for which payment is actually made to Agent under a valid and
collectible insurance policy or under a valid and enforceable indemnity clause,
by-law or agreement, except in respect of any excess beyond payment under such
insurance, clause, by-law or agreement;

            (c) if indemnification is not lawful (and, in this respect, both the
Corporation and Agent have been advised that the Securities and Exchange
Commission believes that indemnification for liabilities arising under the
federal securities laws is against public policy and is, therefore,
unenforceable and that claims for indemnification should be submitted to
appropriate courts for adjudication);

            (d) in connection with any proceeding (or part thereof) initiated by
Agent, or any proceeding by Agent against the Corporation or its directors,
officers, employees or other agents, unless (i) such indemnification is
expressly required to be made by law, (ii) the proceeding was authorized by the
Board of Directors of the Corporation, (iii) such indemnification is provided by
the Corporation, in its sole discretion, pursuant to the powers vested in the
Corporation under the Code, or (iv) the proceeding is initiated pursuant to
Section 10 hereof;

            (e) on account of Agent's acts or omissions that involve intentional
misconduct or a knowing and culpable violation of law;

            (f) on account of Agent's acts or omissions that Agent believes to
be contrary to the best interests of the Corporation or its shareholders or that
involve the absence of good faith on the part of the Agent;

            (g) in respect of any action brought by or in the right of the
Corporation for breach of Agent's duties to the Corporation and its
shareholders:

                (i) on account of any transaction from which Agent derived an
improper personal benefit.

                (ii) on account of Agent's acts or omissions that show a
reckless disregard for the Agent's duty to the Corporation or its shareholders
in circumstances in which Agent was aware, or should have been aware, in the
ordinary course of performing Agent's duties, of a risk of serious injury to the
Corporation or its shareholders.

                (iii) on account of Agent's acts or omissions that constitute an
unexcused pattern of inattention that amounts to an abdication of Agent's duty
to the Corporation or its shareholders.

                (iv) on account of any liability of Agent under Section 310 of
the Code.

                                       3
<PAGE>   4

                (v) on account of any liability of Agent under Section 316 of
the Code.

                (vi) on account of any act or omission of Agent occurring prior
to the date when a provision in the Corporation's Articles of Incorporation
eliminating or limiting the personal liability of the Corporation's directors
for monetary damages in actions brought by or in the right of the Corporation,
as authorized by Section 204(a)(10) of the Code, first became effective;

            (h) in respect of any action by or in the right of the Corporation
to procure a judgment in its favor:

                (i) in respect of any claim, issue or matter as to which Agent
shall have been adjudged to be liable to the Corporation in the performance of
Agent's duty to the Corporation and its shareholders, unless and only to the
extent that the court in which such proceeding is or was pending shall determine
upon application that, in view of all of the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for expenses and then only
to the extent the court shall determine.

                (ii) of amounts paid in settling or otherwise disposing of a
pending action without court approval.

                (iii) of expenses incurred in defending a pending action which
is settled or otherwise disposed of without court approval; or

            (i) except as provided in subdivision (d) or paragraph (4) of
subdivision (e) of Section 317 of the Code, in any circumstance where it
appears:

                (i) that it would be inconsistent with a provision of the
Corporation's Articles of Incorporation or Bylaws, a resolution of the
Corporation's shareholders or an agreement in effect at the time of the accrual
of the alleged cause of action asserted in the proceeding in which the expenses
were incurred or other amounts were paid, which prohibits or otherwise limits
indemnification.

                (ii) that it would be inconsistent with any condition expressly
imposed by a court in approving a settlement.

        6. Continuation of Indemnity. All agreements and obligations of the
Corporation contained herein shall continue during the period Agent is a
director, officer, employee or other agent of the Corporation (or is or was
serving at the request of the Corporation as a director, officer, employee or
other agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise) and shall continue thereafter so long as Agent
shall be subject to any possible claim or threatened, pending or completed
action, suit or proceeding, whether civil, criminal, arbitrational,
administrative or investigative, by reason of the fact that Agent was serving in
the capacity referred to herein.

                                       4
<PAGE>   5

        7. Partial Indemnification. Agent shall be entitled under this Agreement
to indemnification by the Corporation for a portion of the expenses (including
attorneys' fees), witness fees, damages, judgments, fines and amounts paid in
settlement and any other amounts that Agent becomes legally obligated to pay in
connection with any action, suit or proceeding referred to in Section 4 hereof
even if not entitled hereunder to indemnification for the total amount thereof,
and the Corporation shall indemnify Agent for the portion thereof to which Agent
is entitled.

        8. Notice and Other Indemnification Procedures.

            (a) Promptly after receipt by the Agent of notice of the
commencement of or the threat of commencement of any action, suit or proceeding,
the Agent shall, if the Agent believes that indemnification with respect thereto
may be sought from the Corporation under this Agreement, notify the Corporation
of the commencement or threat of commencement thereof; provided, however, that
failure of Agent to provide such notice will not relieve the Corporation of its
liability hereunder if the Corporation receives notice of such action, suit or
proceeding from any other source.

            (b) If, at the time of the receipt of a notice of commencement of an
action, suit or proceeding pursuant to Section 8(a) hereof, the Corporation has
D&O Insurance in effect, the Corporation shall give prompt notice of the
commencement of such action, suit or proceeding to the insurers in accordance
with the procedures set forth in the respective policies. The Corporation shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of the Agent, all amounts payable as a result of such action, suit or
proceeding in accordance with the terms of such policies.

            (c) In the event the Corporation shall be obligated to pay the
expenses of any action, suit or proceeding against the Agent, the Corporation,
if appropriate, shall be entitled to assume the defense of such action, suit or
proceeding, with counsel approved by the Agent, upon the delivery to the Agent
of written notice of its election so to do. After delivery of such notice,
approval of such counsel by the Agent and the retention of such counsel by the
Corporation, the Corporation will not be liable to the Agent under this
Agreement for any fees of counsel subsequently incurred by the Agent with
respect to the same action, suit or proceeding except for reasonable costs of
investigation, provided that (i) the Agent shall have the right to employ his
counsel in any such action, suit or proceeding at the Agent's expense; and (ii)
if (A) the employment of counsel by the Agent has been previously authorized by
the Corporation, (B) the Agent shall have reasonably concluded that there may be
a conflict of interest between the Corporation and the Agent in the conduct of
any such defense or (C) the Corporation shall not, in fact, have employed
counsel to assume the defense of such action, suit or proceeding, the fees and
expenses of Agent's counsel shall be at the expense of the Corporation.

            (d) the Corporation shall not be liable to indemnify Agent under
this Agreement for any amounts paid in settlement of any action or claim
effected without its written consent, which shall not be unreasonably withheld.
The Corporation shall be permitted to settle any action except that it shall not
settle any action or claim in any manner which would impose

                                       5

any penalty or limitation on Agent without Agent's written consent, which may be
given or withheld in Agent's sole discretion.

        9. Expenses. The Corporation shall advance, prior to the final
disposition of any proceeding, promptly following request therefor, all expenses
incurred by Agent in connection with such proceeding upon receipt of an
undertaking by or on behalf of Agent to repay said amounts if it shall be
determined ultimately by a court of last resort that Agent is not entitled to be
indemnified under the provisions of this Agreement, the Bylaws, the Code or
otherwise; provided, however, that no advance shall be paid by the Corporation
in circumstances in which no indemnity shall be payable by the Corporation under
Section 5(i) hereof.

        10. Enforcement. Any right to indemnification or advances granted by
this Agreement to Agent shall be enforceable by or on behalf of Agent in any
court of competent jurisdiction if (i) the claim for indemnification or advances
is denied, in whole or in part, or (ii) no disposition of such claim is made
within ninety (90) days of request therefor. Agent, in such enforcement action,
if successful in whole or in part, shall be entitled to be paid also the expense
of prosecuting his claim. It shall be a defense to any action for which a claim
for indemnification is made under Section 4 hereof (other than an action brought
to enforce a claim for expenses pursuant to Section 9 hereof, provided that the
required undertaking has been tendered to the Corporation) that Agent is not
entitled to indemnification because of the limitations set forth in Section 5
hereof. Neither the failure of the Corporation (including its Board of Directors
or its shareholders) to have made a determination prior to the commencement of
such enforcement action that indemnification of Agent is proper in the
circumstances, nor an actual determination by the Corporation (including its
Board of Directors or its shareholders) that such indemnification is improper
shall be a defense to the action or create a presumption that Agent is not
entitled to indemnification under this Agreement or otherwise.

        11. Subrogation. In the event of payment under this Agreement, the
Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of Agent, who shall execute all documents required and shall
do all acts that may be necessary to secure such rights and to enable the
Corporation effectively to bring suit to enforce such rights.

        12. Non-Exclusivity of Rights. The rights conferred on Agent by this
Agreement shall not be exclusive of any other right which Agent may have or
hereafter acquire under any statute, provision of the Corporation's Articles of
Incorporation or Bylaws, agreement, vote of shareholders or directors, or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding office.

        13. Survival of Rights.

            (a) The rights conferred on Agent by this Agreement shall continue
after Agent has ceased to be a director, officer, employee or other agent of the
Corporation or to serve at the request of the Corporation as a director,
officer, employee or other agent of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise and shall inure to the
benefit of Agent's heirs, executors and administrators.

            (b) The Corporation shall require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Corporation, expressly to
assume and agree to perform this Agreement in the same manner and to the same
extent that the Corporation would be required to perform if no such succession
had taken place.

        14. Interpretation of Agreement. It is understood that the parties
hereto intend this Agreement to be interpreted and enforced so as to provide
indemnification to the Agent to the fullest extent permitted by law.

        15. Severability. If any provision or provisions of this Agreement shall
be held to be invalid, illegal or unenforceable for any reason whatsoever, (i)
the validity, legality and enforceability of the remaining provisions of the
Agreement (including without limitation, all portions of any paragraphs of this
Agreement containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby, and (ii) to the fullest extent
possible, the provisions of this Agreement (including, without limitation, all
portion of any paragraph of this agreement containing any such provision held to
be invalid, illegal or unenforceable, that are not themselves invalid, illegal
or unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable and to give
effect to Section 14 hereof.

        16. Successors and Assigns. The terms of this Agreement shall bind, and
shall inure to the benefit of, the successors and assigns of the parties hereto.

        17. Governing Law. This Agreement shall be governed exclusively by and
construed according to the laws of the State of California as applied to
contracts between California residents entered into and to be performed entirely
within California.

        18. Amendment and Termination. No amendment, modification, termination
or cancellation of this Agreement shall be effective unless in writing signed by
both parties hereto.

        19. Identical Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall for all purposes be deemed to be an
original but all of which together shall constitute but one and the same
Agreement. Only one such counterpart need be produced to evidence the existence
of this Agreement.

        20. Headings. The headings of the sections of this Agreement are
inserted for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction hereof.

        21. Notices. All notices, requests, demands and other communications
hereunder shall be in writing and shall be deemed to have been duly given (i)
upon delivery if delivered by hand to the party to whom such communication was
directed or (ii) upon the third business day after the date on which such
communication was mailed if mailed by certified or registered mail with postage
prepaid:
