     13. INTERPRETATION; CONSTRUCTION.

         The headings set forth in this Agreement are for convenience of
reference only and shall not be used in interpreting this Agreement. This

Employee has been encouraged, and has consulted with, Employee's own independent
counsel and tax advisors with respect to the terms of this Agreement. The

(rather than trial by jury or court or resolution in some other forum) to the
fullest extent permitted by law. Any arbitration proceeding pursuant to this
Agreement shall be conducted by the American Arbitration Association ("AAA") in
Palo Alto, CA under the then existing employment-related AAA arbitration rules.
If for any reason all or part of this arbitration provision is held to be
invalid, illegal, or unenforceable in any respect under any applicable law or
rule in any jurisdiction, such invalidity, illegality or unenforceability will
not affect any other portion of this arbitration provision or any other
jurisdiction, but this provision will be reformed, construed and enforced in
such jurisdiction as if such invalid, illegal or unenforceable part or parts of
this provision had never been contained herein, consistent with the general
intent of the Parties insofar as possible.

I HAVE READ Section 16 AND IRREVOCABLY AGREE TO ARBITRATE ANY DISPUTE IDENTIFIED
ABOVE. ______ (EMPLOYEE'S INITIALS)

     17. INJUNCTIVE RELIEF.

         The Employee is obligated under this Agreement to render services and
comply with covenants of a special, unique, unusual and extraordinary character,
thereby giving this Agreement peculiar value, so that the loss of such service
or violation by the Employee of this Agreement, including, but not limited to,
the Proprietary Information and Inventions Agreement, could not reasonably or
adequately be compensated in damages in an action at law. Therefore,
notwithstanding Section 18 herein, in addition to any other remedies or
sanctions provided by law, whether criminal or civil, and without limiting the
right of the Company and successors or assigns to pursue all other legal and
equitable rights available to them, the Company shall have the right during the
Employee's employment hereunder (or thereafter with respect to obligations
continuing after the termination of this Agreement) to compel specific
performance hereof by the Employee or to obtain temporary and permanent
injunctive relief against violations hereof by the Employee, including, but not
limited to violations of the Proprietary Information and Inventions Agreement,
and, in furtherance thereof, to apply to any court with jurisdiction over the
Parties to enforce the provisions hereof.

     18. TRADE SECRETS OF OTHERS.

         It is the understanding of both the Company and the Employee that the
Employee shall not divulge to the Company and/or its subsidiaries any
confidential information or trade secrets belonging to others, with the
exception of Onprem Networks, Inc., nor shall the Company and/or its affiliates
seek to elicit from the Employee any such information. Consistent with the
foregoing, with the exception of Onprem Networks, Inc., the Employee shall not
provide to the Company and/or its affiliates, and the Company and/or its
affiliates shall not request, any documents or copies of documents containing
such information.

     19. ADVERTISING WAIVER.

         The Employee agrees to permit the Company and/or its affiliates, and
persons or other organizations authorized by the Company and/or its affiliates,
to use, publish and distribute advertising or sales promotional literature
concerning the products and/or services of the

                                       9.

Company and/or its affiliates, or the machinery and equipment used in the
provision thereof, in which the Employee's name and/or pictures of the Employee
taken in the course of the Employee's provision of services to the Company
and/or its affiliates, appear. The Employee hereby waives and releases any claim
or right the Employee may otherwise have arising out of such use, publication or
distribution.

                                       10.

        IN WITNESS WHEREOF, the Parties have executed this Employment Agreement
as of the date first above written.

     In consideration of the payments and other benefits set forth in Section __
of the Employment Agreement dated ___________, to which this form is attached,
I, WIL COCHRAN, hereby furnish COPPER MOUNTAIN NETWORKS, INC. (the "Company"),
with the following release and waiver ("Release and Waiver").

     I hereby release, and forever discharge the Company, its officers,
directors, agents, employees, stockholders, successors, assigns, affiliates,
parent, subsidiaries, and Benefit Plans, of and from any and all claims,
liabilities, demands, causes of action, costs, expenses, attorneys' fees,
damages, indemnities and obligations of every kind and nature, in law, equity,
or otherwise, known and unknown, suspected and unsuspected, disclosed and
undisclosed, arising at any time prior to and including my employment
Termination Date with respect to any claims relating to my employment and the
termination of my employment, including but not limited to, claims pursuant to
any federal, state or local law relating to employment, including, but not
limited to, discrimination claims, claims under the California Fair Employment
and Housing Act, and the Federal Age Discrimination in Employment Act of 1967,
as amended ("ADEA"), or claims for wrongful termination, breach of the covenant
of good faith, contract claims, tort claims, and wage or benefit claims,
including but not limited to, claims for salary, bonuses, commissions, stock,
stock options, vacation pay, fringe benefits, severance pay or any form of
compensation.

     I also acknowledge that I have read and understand Section 1542 of the
California Civil Code which reads as follows: "A GENERAL RELEASE DOES NOT EXTEND
TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT
THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY
AFFECTED HIS SETTLEMENT WITH THE DEBTOR." I hereby expressly waive and
relinquish all rights and benefits under that section and any law of any
jurisdiction of similar effect with respect to any claims I may have against the
Company.

     I acknowledge that, among other rights, I am waiving and releasing any
rights I may have under ADEA, that this Release and Waiver is knowing and
voluntary, and that the consideration given for this Release and Waiver is in
addition to anything of value to which I was already entitled as an Employee of
the Company. I further acknowledge that I have been advised, as required by the
Older Workers Benefit Protection Act, that: (a) the Release and Waiver granted
herein does not relate to claims which may arise after this Release and Waiver
is executed; (b) I have the right to consult with an attorney prior to executing
this Release and Waiver (although I may choose voluntarily not to do so); and if
I am over 40 years of age upon execution of this Release and Waiver: (c) I have
twenty-one (21) days from the date of termination of my employment with the
Company in which to consider this Release and Waiver (although I may choose
voluntarily to execute this Release and Waiver earlier); (d) I have seven (7)
days following the execution of this Release and Waiver to revoke my consent to
this Release and Waiver; and (e) this Release and Waiver shall not be effective
until the seven (7) day revocation period has expired.

MOUNTAIN NETWORKS, INC. (the "Company"), and the compensation now and hereafter
paid to me, I, WIL COCHRAN, hereby agree as follows:

     1. NONDISCLOSURE

        1.1 RECOGNITION OF COMPANY'S RIGHTS; NONDISCLOSURE. At all times during
my employment and thereafter, I will hold in strictest confidence and will not
disclose, use, lecture upon or publish any of the Company's Proprietary
Information (defined below), except as such disclosure, use or publication may
be required in connection with my work for the Company, or unless an officer of
the Company expressly authorizes such in writing. I will obtain Company's
written approval before publishing or submitting for publication any material
(written, verbal, or otherwise) that relates to my work at Company and/or
incorporates any Proprietary Information. I hereby assign to the Company any
rights I may have or acquire in such Proprietary Information and recognize that
all Proprietary Information shall be the sole property of the Company and its
assigns.

        1.2 PROPRIETARY INFORMATION. The term "PROPRIETARY INFORMATION" shall
mean any and all confidential and/or proprietary knowledge, data or information
of the Company. By way of illustration but not limitation, "PROPRIETARY
INFORMATION" includes (a) trade secrets, inventions, mask works, ideas,
processes, formulas, source and object codes, data, programs, other works of
authorship, know-how, improvements, discoveries, developments, designs and
techniques (hereinafter collectively referred to as "INVENTIONS"); and (b)
information regarding plans for research, development, new products, marketing
and selling, business plans, budgets and unpublished financial statements,
licenses, prices and costs, suppliers and customers; and (c) information
regarding the skills and compensation of other employees of the Company.
Notwithstanding the foregoing, it is understood that, at all such times, I am
free to use information which is generally known in the trade or industry, which
is not gained as result of a breach of this Agreement, and my own, skill,
knowledge, know-how and experience to whatever extent and in whichever way I
wish.

        1.3 THIRD PARTY INFORMATION. I understand, in addition, that the Company
has received and in the future will receive from third parties confidential or
proprietary information ("Third Party Information") subject to a duty on the
Company's part to maintain the confidentiality of such information and to use it
only for certain limited purposes. During the term of my employment and
thereafter, I will hold Third Party Information in the strictest confidence and
will not disclose to anyone (other than Company personnel who need to know such
information in connection with their work for the Company) or use, except in
connection with my work for the Company, Third Party Information unless
expressly authorized by an officer of the Company in writing.

        1.4 NO IMPROPER USE OF INFORMATION OF PRIOR EMPLOYERS AND OTHERS. During
my employment by the Company I will not improperly use or disclose any
confidential information or trade secrets, if any, of any former employer or any
other person to whom I have an obligation of confidentiality, and I will not
bring onto the premises of the Company any unpublished documents or any property
belonging to any former employer or any other person to whom I have an
obligation of confidentiality unless consented to in writing by that former
employer or person. I will use in the performance of my duties only information
which is generally known and used by persons with training and experience
comparable to my own, which is common knowledge in the industry or otherwise
legally in the public domain, or which is otherwise provided or developed by the
Company.

     2. ASSIGNMENT OF INVENTIONS.

        2.1 PROPRIETARY RIGHTS. The term "Proprietary Rights" shall mean all
trade secret, patent, copyright, mask work and other intellectual property
rights throughout the world.

        2.2 PRIOR INVENTIONS. Inventions, if any, patented or unpatented, which
I made prior to the

                                      14.

commencement of my employment with the Company are excluded from the scope of
this Agreement. To preclude any possible uncertainty, I have set forth on
Exhibit B-2 (Previous Inventions) attached hereto a complete list of all
Inventions that I have, alone or jointly with others, conceived, developed or
reduced to practice or caused to be conceived, developed or reduced to practice
prior to the commencement of my employment with the Company, that I consider to
be my property or the property of third parties and that I wish to have excluded
from the scope of this Agreement (collectively referred to as "Prior
Inventions"). If disclosure of any such Prior Invention would cause me to
violate any prior confidentiality agreement, I understand that I am not to list
such Prior Inventions in Exhibit B-2 but am only to disclose a cursory name for
each such invention, a listing of the party(ies) to whom it belongs and the fact
that full disclosure as to such inventions has not been made for that reason. A
space is provided on Exhibit B-2 for such purpose. If no such disclosure is
attached, I represent that there are no Prior Inventions. If, in the course of
my employment with the Company, I incorporate a Prior Invention into a Company
product, process or machine, the Company is hereby granted and shall have a
nonexclusive, royalty-free, irrevocable, perpetual, worldwide license (with
rights to sublicense through multiple tiers of sublicensees) to make, have made,
modify, use and sell such Prior Invention. Notwithstanding the foregoing, I
agree that I will not incorporate, or permit to be incorporated, Prior
Inventions in any Company Inventions without the Company's prior written
consent.

        2.3 ASSIGNMENT OF INVENTIONS. Subject to Sections 2.4 and 2.6, I hereby
assign and agree to assign in the future (when any such Inventions or
Proprietary Rights are first reduced to practice or first fixed in a tangible
medium, as applicable) to the Company all my right, title and interest in and to
any and all Inventions (and all Proprietary Rights with respect thereto) whether
or not patentable or registrable under copyright or similar statutes, made or
conceived or reduced to practice or learned by me, either alone or jointly with
others, during the period of my employment with the Company. Inventions assigned
to the Company, or to a third party as directed by the Company pursuant to this
Section 2, are hereinafter referred to as "Company Inventions".

        2.4 NONASSIGNABLE INVENTIONS. This Agreement does not apply to an
Invention which qualifies fully as a nonassignable Invention under Section 2870
of the California Labor Code (hereinafter "Section 2870"). I have reviewed the
notification on Exhibit B-1 (Limited Exclusion Notification) and agree that my
signature acknowledges receipt of the notification.

        2.5 OBLIGATION TO KEEP COMPANY INFORMED. During the period of my
employment and for six (6) months after termination of my employment with the
Company, I will promptly disclose to the Company fully and in writing all
Inventions authored, conceived or reduced to practice by me, either alone or
jointly with others. In addition, I will promptly disclose to the Company all
patent applications filed by me or on my behalf within a year after termination
of employment. At the time of each such disclosure, I will advise the Company in
writing of any Inventions that I believe fully qualify for protection under
Section 2870; and I will at that time provide to the Company in writing all
evidence necessary to substantiate that belief. The Company will keep in
confidence and will not use for any purpose or disclose to third parties without
my consent any confidential information disclosed in writing to the Company
pursuant to this Agreement relating to Inventions that qualify fully for
protection under the provisions of Section 2870. I will preserve the
confidentiality of any Invention that does not fully qualify for protection
under Section 2870.

        2.6 GOVERNMENT OR THIRD PARTY. I also agree to assign all my right,
title and interest in and to any particular Company Invention to a third party,
including without limitation the United States, as directed by the Company.

        2.7 WORKS FOR HIRE. I acknowledge that all original works of authorship
which are made by me (solely or jointly with others) within the scope of my
employment and which are protectable by copyright are "works made for hire",
pursuant to United States Copyright Act (17 U.S.C., Section 101).

        2.8 ENFORCEMENT OF PROPRIETARY RIGHTS. I will assist the Company in
every proper way to obtain, and from time to time enforce, United States and
foreign Proprietary Rights relating to Company Inventions in any and all
countries. To that end I will execute, verify and deliver such documents and
perform such other acts (including appearances as a witness) as the Company may
reasonably request for use in applying for, obtaining, perfecting, evidencing,
sustaining and enforcing such Proprietary

                                      15.

Rights and the assignment thereof. In addition, I will execute, verify and
deliver assignments of such Proprietary Rights to the Company or its designee.
My obligation to assist the Company with respect to Proprietary Rights relating
to such Company Inventions in any and all countries shall continue beyond the
termination of my employment, but the Company shall compensate me at a
reasonable rate after my termination for the time actually spent by me at the
Company's request on such assistance.

In the event the Company is unable for any reason, after reasonable effort, to
secure my signature on any document needed in connection with the actions
specified in the preceding paragraph, I hereby irrevocably designate and appoint
the Company and its duly authorized officers and agents as my agent and attorney
in fact, which appointment is coupled with an interest, to act for and in my
behalf to execute, verify and file any such documents and to do all other
lawfully permitted acts to further the purposes of the preceding paragraph with
the same legal force and effect as if executed by me. I hereby waive and
quitclaim to the Company any and all claims, of any nature whatsoever, which I
now or may hereafter have for infringement of any Proprietary Rights assigned
hereunder to the Company.

     3.  RECORDS. I agree to keep and maintain adequate and current records (in
the form of notes, sketches, drawings and in any other form that may be required
by the Company) of all Proprietary Information developed by me and all
Inventions made by me during the period of my employment at the Company, which
records shall be available to and remain the sole property of the Company at all
times.

     4.  ADDITIONAL ACTIVITIES. I agree that during the period of my employment
by the Company I will not, without the Company's express written consent, engage
in any employment or business activity which is competitive with, or would
otherwise conflict with, my employment by the Company. I agree further that for
the period of my employment by the Company and for one (l) year after the date
of termination of my employment by the Company I will not induce any employee of
the Company to leave the employ of the Company.

     5.  NO CONFLICTING OBLIGATION. I represent that my performance of all the
terms of this Agreement and as an Employee of the Company does not and will not
breach any agreement to keep in confidence information acquired by me in
confidence or in trust prior to my employment by the Company. I have not entered
into, and I agree I will not enter into, any agreement either written or oral in
conflict herewith.

     6.  RETURN OF COMPANY DOCUMENTS. When I leave the employ of the Company, I
will deliver to the Company any and all drawings, notes, memoranda,
specifications, devices, formulas, and documents, together with all copies
thereof, and any other material containing or disclosing any Company Inventions,
Third Party Information or Proprietary Information of the Company. I further
agree that any property situated on the Company's premises and owned by the
Company, including disks and other storage media, filing cabinets or other work
areas, is subject to inspection by Company personnel at any time with or without
notice. Prior to leaving, I will cooperate with the Company in completing and
signing the Company's termination statement.

     7.  LEGAL AND EQUITABLE REMEDIES. Because my services are personal and
unique and because I may have access to and become acquainted with the
Proprietary Information of the Company, the Company shall have the right to
enforce this Agreement and any of its provisions by injunction, specific
performance or other equitable relief, without bond and without prejudice to any
other rights and remedies that the Company may have for a breach of this
Agreement.

     8.  NOTICES. Any notices required or permitted hereunder shall be given to
the appropriate party at the address specified below or at such other address as
the Party shall specify in writing. Such notice shall be deemed given upon
personal delivery to the appropriate address or if sent by certified or
registered mail, three (3) days after the date of mailing.

     9.  NOTIFICATION OF NEW EMPLOYER. In the event that I leave the employ of
the Company, I hereby consent to the notification of my new employer of my
rights and obligations under this Agreement.

     10. GENERAL PROVISIONS.

         10.1 GOVERNING LAW; CONSENT TO PERSONAL JURISDICTION. This Agreement
will be governed by and construed according to the laws of the State of
California, as such laws are applied to agreements entered into and to be
performed entirely within California between California residents. I

                                      16.

hereby expressly consent to the personal jurisdiction of the state and federal
courts located in San Diego County, California for any lawsuit filed there
against me by Company arising from or related to this Agreement.

         10.2 SEVERABILITY. In case any one or more of the provisions contained
in this Agreement shall, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect the other provisions of this Agreement, and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision had
never been contained herein. If moreover, any one or more of the provisions
contained in this Agreement shall for any reason be held to be excessively broad
as to duration, geographical scope, activity or subject, it shall be construed
by limiting and reducing it, so as to be enforceable to the extent compatible
with the applicable law as it shall then appear.

         10.3 SUCCESSORS AND ASSIGNS. This Agreement will be binding upon my
heirs, executors, administrators and other legal representatives and will be for
the benefit of the Company, its successors, and its assigns.

         10.4 SURVIVAL. The provisions of this Agreement shall survive the
termination of my employment and the assignment of this Agreement by the Company
to any successor in interest or other assignee.

         10.5 EMPLOYMENT. I agree and understand that nothing in this Agreement
shall confer any right with respect to continuation of employment by the
Company, nor shall it interfere in any way with my right or the Company'S right
to terminate my employment at any time, with or without Cause.

         10.6 WAIVER. No waiver by the Company of any breach of this Agreement
shall be a waiver of any preceding or succeeding breach. No waiver by the
Company of any right under this Agreement shall be construed as a waiver of any
other right. The Company shall not be required to give notice to enforce strict
adherence to all terms of this Agreement.

         10.7 ENTIRE AGREEMENT. The obligations pursuant to Sections 1 and 2 of
this Agreement shall apply to any time during which I was previously employed,
or am in the future employed, by the Company as a consultant if no other
agreement governs nondisclosure and assignment of inventions during such period.
This Agreement is the final, complete and exclusive agreement of the Parties
with respect to the subject matter hereof and supersedes and merges all prior
discussions between us. No modification of or amendment to this Agreement, nor
any waiver of any rights under this Agreement, will be effective unless in
writing and signed by the Party to be charged. Any subsequent change or changes
in my duties, salary or compensation will not affect the validity or scope of
this Agreement.

         This Agreement shall be effective as of the first day of my employment
with the Company, namely: _______________, 20__.

         I HAVE READ THIS AGREEMENT CAREFULLY AND UNDERSTAND ITS TERMS. I HAVE
COMPLETELY FILLED OUT EXHIBIT B-1 TO THIS AGREEMENT.

                         LIMITED EXCLUSION NOTIFICATION

         THIS IS TO NOTIFY THE EMPLOYEE in accordance with Section 2872 of the
California Labor Code that the foregoing Agreement between the Employee and the
Company does not require the Employee to assign or offer to assign to the
Company any invention that the Employee developed entirely on your own time
without using the Company's equipment, supplies, facilities or trade secret
information except for those inventions that either:

         1.       RELATE AT THE TIME OF CONCEPTION OR REDUCTION TO PRACTICE OF
                  THE INVENTION TO THE COMPANY'S BUSINESS, OR ACTUAL OR
                  DEMONSTRABLY ANTICIPATED RESEARCH OR DEVELOPMENT OF THE
                  COMPANY;

         2.       RESULT FROM ANY WORK PERFORMED BY THE EMPLOYEE FOR THE
                  COMPANY.

         To the extent a provision in the foregoing Agreement purports to
require the Employee to assign an invention otherwise excluded from the
preceding paragraph, the provision is against the public policy of this state
and is unenforceable.

         This limited exclusion does not apply to any patent or invention
covered by a contract between the Company and the United States or any of its
agencies requiring full title to such patent or invention to be in the United
States.

         I ACKNOWLEDGE RECEIPT of a copy of this notification.

                            NONCOMPETITION AGREEMENT

     THIS NON-COMPETITION AGREEMENT (the "AGREEMENT") is made and entered into
as of February 29, 2000 (the "AGREEMENT DATE"), by and between COPPER MOUNTAIN
NETWORKS, INC., a Delaware corporation (the "PARENT"), ONPREM NETWORKS, INC., a
California corporation ("COMPANY"), and WIL COCHRAN ("Employee"). Capitalized
terms used herein and not otherwise defined shall have the meanings given to
them in the Merger Agreement.

                                    RECITALS

     A. As a key employee, substantial stockholder and optionholder of the
Company, Employee has obtained extensive and valuable knowledge and confidential
information concerning the business of the Company.

     B. Parent and the Company have entered into an Agreement and Plan of Merger
and Reorganization (the "MERGER AGREEMENT") of even date herewith, providing for
the acquisition by Parent of the Company pursuant to a merger of a wholly owned
subsidiary of Parent ("MERGER SUB") with and into the Company (the "MERGER").
This Agreement will become effective on the date the Merger becomes effective
(the "Closing Date").

     C. In connection with the Merger, Employee (i) will receive substantial
benefits as a result of the Merger; (ii) has been offered employment with Parent
contingent upon the occurrence of and following the Closing Date; and (iii) will
be paid four hundred thousand dollars ($400,000) during the term of this
Agreement, contingent upon Employee's continued compliance with the terms of
this Agreement. Employee will be paid one hundred twenty-five thousand dollars
($125,000) in each of the first and second years of this Agreement, in equal
monthly installments. Employee will be paid one hundred fifty thousand dollars
($150,000) during the third year of this Agreement in equal monthly
installments. The Employee's right to receive the payments provided for herein
shall cease and be rendered a nullity immediately should the Employee violate
any provision of this Agreement. Employee's right to receive the payments
provided for herein are not contingent on Employee's employment with the
Company. As an inducement to Parent and Merger Sub to consummate the Merger and
enable Parent and Merger Sub to secure more fully the benefits of the Merger and
for the additional consideration provided herein, Employee has agreed not to
compete in the manner and to the extent herein set forth in this Agreement.

     D. Employee's obligations under this Agreement are separate and independent
from Employee's obligations under the Employment Agreement which Employee will
simultaneously enter into with the Company. Employee's obligations under this
Agreement will remain in full force and effect during the term of the
Noncompetition Agreement, regardless of whether Employee remains employed with
the Company.

     E. Parent has requested, as a condition precedent to executing the Merger
Agreement and consummating the transactions contemplated by the Merger
Agreement, that Employee execute and deliver this Agreement, and Employee
desires to enter into this Agreement.

                                       1.

                                    AGREEMENT

     NOW, THEREFORE, in consideration of the mutual covenants herein
contemplated and intending to be legally bound hereby, the parties hereto agree
as follows:

     1. RESTRICTION ON COMPETITION. In order to induce the Company to consummate
the Merger and for other good and valuable consideration as provided herein,
Employee agrees that, during the Noncompetition Period, Employee shall not:

        (a) engage directly or indirectly in Competition in any Restricted
Territory; or

        (b) directly or indirectly be or become an officer, director,
stockholder, owner, co-owner, Affiliate, partner, promoter, employee, agent,
representative, designer, consultant, advisor, manager, licensor, sublicensor,
licensee or sublicensee of, for or to, or otherwise be or become associated with
or acquire or hold (of record, beneficially or otherwise) any direct or indirect
interest in, any Person that engages directly or indirectly in Competition in
any Restricted Territory;

     provided, however, that Employee may, without violating this Section 1,
own, as a passive investment, shares of capital stock of a publicly-held
corporation that engages in Competition if (i) such shares are actively traded
on an established national securities market in the United States, (ii) the
number of shares of such corporation's capital stock that are owned beneficially
(directly or indirectly) by Employee and the number of shares of such
corporation's capital stock that are owned beneficially (directly or indirectly)
by Employee's Affiliates collectively represent less than one percent of the
total number of shares of such corporation's capital stock outstanding, and
(iii) neither Employee nor any Affiliate of Employee is otherwise associated
directly or indirectly with such corporation or with any Affiliate of such
corporation.

     2. NO HIRING OR SOLICITATION OF EMPLOYEES. Employee agrees that, during the
Noncompetition Period, Employee shall not, and shall not permit any of his
Affiliates to: (a) hire any Specified Employee, or (b) directly or indirectly,
personally or through others, encourage, induce, attempt to induce, solicit or
attempt to solicit (on Employee's own behalf or on behalf of any other Person)
any Specified Employee or any other employee to leave his or her employment with
Parent, the Company or any of Parent's other subsidiaries. (For purposes of this
Section 2, "Specified Employee" shall mean any individual who (i) is or was an
employee of Parent, the Company or any of the Company's other subsidiaries on
the date of this Agreement or during the 180-day period ending on the date of
this Agreement, and (ii) remains or becomes an employee of Parent, the Company
or any of the Company's other subsidiaries on the date of this Agreement or at
any time during the Noncompetition Period.

     3. ACKNOWLEDGEMENTS BY EMPLOYEE. Employee acknowledges that by virtue of
his position with the Company he or she has developed considerable expertise in
the business operations of the Company and has had extensive access to trade
secrets and other confidential information of the Company. Employee recognizes
that Parent would be irreparably damaged, and its substantial investment in the
Company materially impaired, if Employee were to enter into an activity
competing with the business of Parent, the Company (or any subsidiary, successor
or acquiror of Parent or the Company) in violation of the terms of this
Agreement or if

                                       2.

Employee were to disclose or make unauthorized use of any confidential
information concerning the business of Parent, the Company (or any subsidiary,
successor or acquiror of Parent or the Company). Accordingly, Employee expressly
acknowledges that he or she is voluntarily entering into this Agreement and that
the terms and conditions of this Agreement are fair and reasonable to Employee
in all respects.

     4. CONFIDENTIALITY. Employee agrees that he shall hold all Confidential
Information in strict confidence and shall not at any time (whether during or
after the Noncompetition Period): (a) reveal, report, publish, disclose or
transfer any Confidential Information to any Person (other than Parent or the
Company), except in the performance of his obligations as an employee of Parent;
(b) use any Confidential Information for any purpose, except in the performance
of his obligations as an employee of Parent; or (c) use any Confidential
Information for the benefit of any Person (other than Parent or the Company.)
Employee agrees that as a condition of his employment with Parent, he will
execute the Proprietary Information & Inventions Agreement, attached to the
Employment Agreement he will enter into with Parent effective the Closing Date.

     5. REPRESENTATIONS AND WARRANTIES. Employee represents and warrants, to and
for the benefit of the Indemnitees, that: (a) he has full power and capacity to
execute and deliver, and to perform all of his obligations under, this
Agreement; and (b) neither the execution and delivery of this Agreement nor the
performance of this Agreement will result directly or indirectly in a violation
or breach of (i) any agreement or obligation by which Employee or any of his
Affiliates is or may be bound, or (ii) any law, rule or regulation. Employee's
representations and warranties shall survive the expiration of the
Noncompetition Period for an unlimited period of time.

     6. INJUNCTIVE RELIEF. Employee agrees that he is obligated under this
Agreement to render services and comply with covenants of a special, unique,
unusual and extraordinary character, thereby giving this Agreement peculiar
value so that the loss of such service or violation by Employee of this
Agreement, including but not limited to, Sections 1, 3 and 4 herein could not
reasonably or adequately be compensated in damages at law. Therefore,
notwithstanding Section 15 herein, Employee agrees that, in the event of any
breach or threatened breach by Employee of any covenant or obligation contained
in this Agreement, each of Parent, the Company and any of Parent's or the
Company's other subsidiaries and the other Indemnitees shall be entitled (in
addition to any other remedy that may be available to it, including monetary
damages) to seek and obtain (a) a decree or order of specific performance to
enforce the observance and performance of such covenant or obligation, and (b)
an injunction restraining such breach or threatened breach. Employee further
agrees that no Indemnitee shall be required to obtain, furnish or post any bond
or similar instrument in connection with or as a condition to obtaining any
remedy referred to in this Section 6, and Employee irrevocably waives any right
he may have to require any Indemnitee to obtain, furnish or post any such bond
or similarly instrument.

     7. INDEMNIFICATION. Without in any way limiting any of the rights or
remedies otherwise available to any of the Indemnitees, Employee shall indemnify
and hold harmless each Indemnitee against and from any loss, damage, injury,
harm, detriment, lost opportunity, liability, exposure, claim, demand,
settlement, judgment, award, fine, penalty, tax, fee (including attorneys'
fees), charge or expense (whether or not relating to any third-party claim) that
is

                                       3.

directly or indirectly suffered or incurred at any time (whether during or after
the Noncompetition Period) by such Indemnitee, or to which such Indemnitee
otherwise becomes subject at any time (whether during or after the
Noncompetition Period), and that arises directly or indirectly out of or by
virtue of, or relates directly or indirectly to, (a) any inaccuracy in or breach
of any representation or warranty contained in this Agreement, or (b) any
failure on the part of Employee to observe, perform or abide by, or any other
breach of, any restriction, covenant, obligation or other provision contained in
this Agreement.

     8. NON-EXCLUSIVITY. The rights and remedies of Parent, the Company, and the
other Indemnitees under this Agreement are not exclusive of or limited by any
other rights or remedies which they may have, whether at law, in equity, by
contract or otherwise, all of which shall be cumulative (and not alternative).
Without limiting the generality of the foregoing, the rights and remedies of
Parent, the Company, and the other Indemnitees under this Agreement, and the
obligations and liabilities of Employee under this Agreement, are in addition to
their respective rights, remedies, obligations and liabilities under the law of
unfair competition, under laws relating to misappropriation of trade secrets,
under other laws and common law requirements and under all applicable rules and
regulations. Nothing in this Agreement shall limit any of Employee's
obligations, or the rights or remedies of Parent, the Company or any of the
other Indemnitees, under the Merger Agreement; and nothing in the Merger
Agreement shall limit any of Employee's obligations, or any of the rights or
remedies of Parent, the Company or any of the other Indemnitees, under this
Agreement. No breach on the part of Parent, the Company or any other party of
any covenant or obligation contained in the Merger Agreement, or any other
agreement shall limit or otherwise affect any right or remedy of Parent, the
Company or any of the other Indemnitees under this Agreement.

     9. SEVERABILITY. If any provision of this Agreement or any part of any such
provision is held under any circumstances to be invalid or unenforceable in any
jurisdiction, then (a) such provision or part thereof shall, with respect to
such circumstances and in such jurisdiction, be deemed amended to conform to
applicable laws so as to be valid and enforceable to the fullest possible
extent, (b) the invalidity or unenforceability of such provision or part thereof
under such circumstances and in such jurisdiction shall not affect the validity
or enforceability of such provision or part thereof under any other
circumstances or in any other jurisdiction, and (c) the invalidity or
unenforceability of such provision or part thereof shall not affect the validity
or enforceability of the remainder of such provision or the validity or
enforceability of any other provision of this Agreement. Each provision of this
Agreement is separable from every other provision of this Agreement, and each
part of each provision of this Agreement is separable from every other part of
such provision.

     10. GOVERNING LAW. This Agreement shall be construed in accordance with,
and governed in all respects by, the laws of the State of California (without
giving effect to principles of conflicts of laws).

     11. WAIVER. No failure on the part of Parent, the Company or any other
Indemnitee to exercise any power, right, privilege or remedy under this
Agreement, and no delay on the part of Parent, the Company or any other
Indemnitee in exercising any power, right, privilege or remedy under this
Agreement, shall operate as a waiver of such power, right, privilege or remedy;
and no single or partial exercise of any such power, right, privilege or remedy
shall preclude any other or further exercise thereof or of any other power,
right, privilege or remedy.

                                       4.

No Indemnitee shall be deemed to have waived any claim of such Indemnitee
arising out of this Agreement, or any power, right, privilege or remedy of such
Indemnitee under this Agreement, unless the waiver of such claim, power, right,
privilege or remedy is expressly set forth in a written instrument duly executed
and delivered on behalf of such Indemnitee; and any such waiver shall not be
applicable or have any effect except in the specific instance in which it is
given.

     12. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and shall
inure to the benefit of Employee and his heirs, executors, estate, personal
representatives and legal representatives. This Agreement shall be binding upon
and shall inure to the benefit of Parent, the Company, and the other
Indemnitees. Each of Parent, the Company, and the other Indemnitees may freely
assign any or all of its rights under this Agreement, at any time, in whole or
in part, to any Person without obtaining the consent or approval of Employee or
of any other Person. Because of the unique and personal nature of Employee's
duties under this Agreement, neither this Agreement nor any rights or
obligations under this Agreement shall be assignable by Employee.

     13. INTEGRATION. This Agreement forms the complete and exclusive statement
of the terms of Employee's agreement with Parent and the Company regarding the
subject matter herein.

     14. FURTHER ASSURANCES. Employee shall (at Employee's sole expense) execute
and/or cause to be delivered to each Indemnitee such instruments and other
documents, and shall (at Employee's sole expense) take such other actions, as
such Indemnitee may reasonably request at any time (whether during or after the
Noncompetition Period) for the purpose of carrying out or evidencing any of the
provisions of this Agreement.

     15. ARBITRATION. To ensure rapid and economical resolution of any disputes
which may arise under this Agreement, Employee and the Company agree that any
and all disputes or controversies of any nature whatsoever, arising from or
regarding the interpretation, performance, enforcement or breach of this
Agreement shall be resolved by confidential, final and binding arbitration
(rather than trial by jury or court or resolution in some other forum) to the
fullest extent permitted by law. Any arbitration proceeding pursuant to this
Agreement shall be conducted by the American Arbitration Association ("AAA") in
Palo Alto, California under the then existing employment-related AAA arbitration
rules. If for any reason all or part of this arbitration provision is held to be
invalid, illegal, or unenforceable in any respect under any applicable law or
rule in any jurisdiction, such invalidity, illegality or unenforceability will
not affect any other portion of this arbitration provision or any other
jurisdiction, but this provision will be reformed, construed and enforced in
such jurisdiction as if such invalid, illegal or unenforceable part or parts of
this provision had never been contained herein, consistent with the general
intent of the parties insofar as possible.
