7.     SEVERANCE BENEFITS.

       (a)    TERMINATION NOT FOR CAUSE.  Except as provided in Section 7(b), if
the Board of Directors terminates Key Executive's employment for any reason
other than Cause, or Key Executive's employment is terminated by Constructive
Termination as defined in this Agreement, the Key Executive shall be entitled to
receive the following severance benefits:

              (1)    GUARANTEED SEVERANCE PAYMENTS.  Subject to Key Executive
       entering into a Release of Claims (in a form substantially similar to the
       form of release of claims attached as Exhibit A), Key Executive shall be
       entitled to receive severance payments for twelve (12) months from the
       date of termination at Key Executive's then current base salary, which
       may be greater than, but will not be less than the Base Compensation (the
       "Guaranteed Severance Payment").  The Guaranteed Severance Payment will
       be paid to Key Executive in accordance with the Company's standard
       payroll practices.   Upon termination, Key Executive will also be
       entitled to receive a pro-rated portion of his then current targeted
       bonus for the fiscal year of his termination as described in Section 3(b)
       based on the date that Key Executive's employment is terminated.

              (2)     MEDICAL BENEFITS. The Company, at the Company's sole
       expense, shall provide Key Executive  (and, if applicable, his eligible
       dependents) with the same level of health coverage and benefits as in
       effect for Key Executive (and, if applicable, his eligible dependents) on
       the day immediately preceding the day of the Key Executive's termination
       of employment (the "Company-Paid Coverage"); provided, however, that: (i)
       Key Executive and each eligible dependent constitutes a qualified
       beneficiary, as defined in Section 4980B(g)(1) of the Internal Revenue
       Code of 1986, as amended (collectively, "Qualified Beneficiaries"); (ii)
       each Qualified Beneficiary elects continuation coverage under the
       Consolidated Omnibus Budget Reconciliation Act of 1985, as amended
       ("COBRA"), within the time period prescribed pursuant to COBRA; and (iii)
       if the health coverage is no longer offered by the Company to its current
       employees, then the Company shall be under no obligation to continue the
       existing coverage for Key Executive (and, if applicable, his eligible
       dependents).  Such Company-Paid Coverage shall continue in effect for
       each Qualified Beneficiary until the earlier of (i) the Qualified
       Beneficiary is no longer eligible to receive continuation coverage under
       COBRA, or (ii) thirty (30) months following termination of employment.

Except as described in subsection (2)(ii) above, the Company's obligations under
paragraphs 1 and 2 of this Section 7(a) shall terminate upon Key Executive's
breach of his agreements under Section 8 hereof.

       (b)    DISABILITY; DEATH.  If the Company terminates the Key
Executive's employment as a result of the Key Executive's Disability or if
the Key Executive's employment terminates due to the death of the Key
Executive, then the Key Executive shall not be entitled to receive severance
or other benefits pursuant to this Agreement, unless the Company has no
benefit plan in place to account for death or disability of employees, in
which case Key Executive will be entitled to receive the Guaranteed Severance
Payment specified in Section 7(a)(1).  Key Executive shall remain eligible
for those severance and other benefits (if any) as may then be available
under the Company's then existing severance and benefits plans and policies
at the time of Key Executive's termination or death.

                                                                             4
<PAGE>

        (c)   STOCK OPTIONS.  All of Key Executive's options not
otherwise forfeited under the terms of this Agreement will continue to vest
during the twelve month Severance Benefits Period.  Key Executive will
forfeit options that have not vested as of the end of the twelve month
Severance Benefits Period.  Key Executive and the Company will negotiate a
consulting agreement under which Key Executive will provide advisory services
to the Company's Key Executive management or board of directors during the
twelve months after his termination. In the event the Company undergoes a
Change in Control, or other material event in which the Company or Key
Executive's position undergoes a material change as a result of the material
event, Key Executive's stock options will accelerate vesting such that fifty
percent  (50%) of the options will vest at the completion of the Change in
Control, or material event, and the remaining fifty percent (50%) will vest
90 days thereafter. If there is an inconsistency between this Agreement and
the Company's stock option plans or a stock option agreement, the terms of
this Agreement shall prevail.

       (d)    INSIDER TRADING.  While Key Executive receives severance payments,
Key Executive will no longer be deemed a Section 16(b) officer, but agrees to be
considered an "insider" and comply with the Company's Insider Trading Policy,
unless otherwise agreed to in writing by the Company for matters related to
reduction of Key Executive's stock holding.

8.     COVENANTS NOT TO COMPETE AND NOT TO SOLICIT.

       (a)    While employed by the Company, Key Executive agrees that he shall
not, directly or indirectly, engage on his own behalf, or as owner, manager,
advisor, principal, agent, partner, employee consultant, director, officer,
stockholder or other proprietor owning more than a five percent (5%) interest,
in any firm, corporation, partnership or other organization which is in the
business of manufacturing, selling or distributing products in competition with
the products of the Company.  In case of any such ownership or participation,
Key Executive shall furnish a detailed statement thereof to the Board of
Directors of the Company, and, as from time to time requested by said Board,
resubmit for approval a detailed statement thereof, which statement may be
approved by said Board as not constituting such a violation or conflict, and in
the event said Board determines that such violation or conflict exists, Key
Executive shall immediately divest himself of such ownership or participation
(or of representing or promoting others engaged in any such business).  It is
intended and agreed that during the term of this Agreement, Key Executive will
not knowingly perform any act  which may confer any competitive benefit or
advantage upon any enterprise competing with the Company or any successor.

       (b)    Upon the termination of the Key Executive 's employment with
the Company within the terms of Section 7(a) and for a period of  eighteen
(18) months thereafter, Key Executive agrees that he shall not, on his own
behalf, or as owner, manager, advisor, principal, agent, partner, employee
consultant, director, officer, stockholder or other proprietor owning more
than a five percent (5%) interest of any business entity, or otherwise, in
any territory in which the Company is actively engaged in business: (i) open
or operate any business which is in competition with any business of the
Company, (ii) act as an employee, agent, advisor or consultant of any
competitor of the Company, (iii)  take any action to or do anything
reasonably intended to divert business from the Company or influence or
attempt to influence any existing customers of the Company to cease doing
business with the Company or to alter its business relationship with the
Company, or (iv) take any action or do anything reasonably intended to
influence any suppliers of the Company to cease doing business with the
Company or to alter its business relationship with the Company.  Key
Executive further covenants and agrees that he will not

                                                                             5
<PAGE>

for himself or on behalf of any other person, partnership, firm, association
or corporation in any territory served by the Company, directly or indirectly
solicit or accept business from any of the Company's existing customers for
the purchase or sale of products or services of a like kind to those sold or
provided the Company. The foregoing covenant shall not be deemed to prohibit
Key Executive from acquiring an investment not more than one percent (1%) of
the capital stock of a competing business, whose stock is traded on a
national securities exchange or through the automated quotation system of a
registered securities association.

       (c)    While employed by the Company and upon the termination of the Key
Executive's employment with the Company within the terms of Section 7(a) and for
a period of eighteen (18) months thereafter, Key Executive agrees that he shall
not either directly solicit, induce, attempt to hire, recruit, encourage, take
away, hire any employee of the Company or cause any employee of the Company to
leave his or her employment either for Key Executive or for any other entity or
person.

       (d)    Key Executive represents that he (i) is familiar with the
foregoing covenants not to compete and not to directly solicit, and (ii) is
fully aware of his obligations hereunder, including, without limitation, the
reasonableness of the length of time, scope and geographic coverage of these
covenants. Key Executive agrees that the provisions of this Section 8 contain
restrictions that are not greater than necessary to protect the interests of the
Company.  In the event of the breach or threatened breach by Key Executive of
this Section 8, the Company, in addition to all other remedies available to it
at law or in equity, will be entitled to seek injunctive relief and/or specific
performance to enforce this Section 8.

       (e)    Company will respond within 14 days to any written request by  to
exclude a particular company or business entity from the scope of this Section
8.  Company will not unreasonably deny such a request.  The parties agree that a
passive financial investment by Key Executive in a third party will not
constitute competition within the scope of this Section 8.

Agreement shall have the following meanings for the purposes of this Agreement
only:

4.     OTHER BUSINESS AFFILIATIONS.   In addition to Executive's obligations
under Section 8, Executive agrees that, without the approval of the Company,

business expenses incurred in the performance of his duties hereunder on

Company's then existing severance and benefit plans and policies at the time
of Executive's termination.

       (c)    TERMINATION NOT FOR CAUSE   If the Company terminates
Executive's employment for any reason other than Cause, or Executive's
employment is terminated by Constructive Termination as defined in this
Agreement, the Executive shall be entitled to receive the severance benefits

writing its waiver of the forgoing.

7.     SEVERANCE BENEFITS.

       (a)    TERMINATION NOT FOR CAUSE.  Except as provided in Section 7(b),
if the Board of Directors terminates Executive's employment for any reason

Termination as defined in this Agreement, the Executive shall be entitled to
receive the following severance benefits:

                     (1)    GUARANTEED SEVERANCE PAYMENTS.  Subject to Executive
       entering into a Release of Claims (in a form substantially similar to the
       form of release of claims attached as Exhibit A), Executive shall be
       entitled to receive severance payments for twelve (12) months from the
       date of termination at Executive's then current base salary, which may be
       greater than, but will not be less than the Base Compensation (the
       "Guaranteed Severance Payment").  The Guaranteed Severance Payment will
       be paid to Executive in accordance with the Company's standard payroll
       practices.   Upon termination, Executive will also be entitled to receive
       a pro-

                                                                             3
<PAGE>

       rated portion of his then current targeted bonus for the fiscal year
       of his termination as described in Section 3(b) based on the date that
       Executive's employment is terminated.

                     (2)    MEDICAL BENEFITS. The Company, at the Company's
       sole expense, shall provide Executive  (and, if applicable, his
       eligible dependents) with the same level of health coverage and
       benefits as in effect for Executive (and, if applicable, his eligible
       dependents) on the day immediately preceding the day of the
       Executive's termination of employment (the "Company-Paid Coverage");
       provided, however, that: (i) Executive and each eligible dependent
       constitutes a qualified beneficiary, as defined in Section 4980B(g)(1)
       of the Internal Revenue Code of 1986, as amended (collectively,
       "Qualified Beneficiaries"); (ii) each Qualified Beneficiary elects
       continuation coverage under the Consolidated Omnibus Budget
       Reconciliation Act of 1985, as amended ("COBRA"), within the time
       period prescribed pursuant to COBRA; and (iii) if the health coverage
       is no longer offered by the Company to its current employees, then the
       Company shall be under no obligation to continue the existing coverage
       for Executive (and, if applicable, his eligible dependents).  Such
       Company-Paid Coverage shall continue in effect for each Qualified
       Beneficiary until the earlier of (i) the Qualified Beneficiary is no
       longer eligible to receive continuation coverage under COBRA, or (ii)
       thirty (30) months following termination of employment.

Except for those obligations in subsection (2)(ii) above, the Company's
obligations under paragraphs 1 and 2 of this Section 7(a) shall terminate
upon Executive's breach of his agreements under Section 8 hereof.

       (b)    DISABILITY; DEATH.  If the Company terminates the Executive's
employment as a result of the Executive's Disability or if the Executive's
employment terminates due to the death of the Executive, then the Executive
shall not be entitled to receive severance or other benefits pursuant to this
Agreement, unless the Company has no benefit plan in place to account for
death or disability of employees, in which case Executive will be entitled to
receive the Guaranteed Severance Payment specified in Section 7(a)(1).
Executive shall remain eligible for those severance and other benefits (if
any) as may then be available under the Company's then existing severance and
benefits plans and policies at the time of Executive's termination or death.

        (c)   STOCK OPTIONS.  All of Executive's options not otherwise
forfeited under the terms of this Agreement will continue to vest during the
twelve month Severance Benefits Period.  Executive will forfeit options that
have not vested as of the end of the twelve month Severance Benefits Period.
Executive and the Company will negotiate a consulting agreement under which
Executive will provide advisory services to the Company's executive
management or board of directors during the 12 months after his termination.
If there is an inconsistency between this Agreement and the Company's stock
option plans or a stock option agreement, the terms of this Agreement will
prevail.

       (d)    INSIDER TRADING.  While Executive receives severance payments,
Executive will no longer be deemed a Section 16(b) officer, but agrees to be
considered an "insider" and comply with the Company's Insider Trading Policy,
unless otherwise agreed to in writing by the Company for matters related to
reduction of Executive's stock holding.

                                                                             4

8.     COVENANTS NOT TO COMPETE AND NOT TO SOLICIT.

       (a)    While employed by the Company, Executive agrees that he shall
not, directly or indirectly, engage on his own behalf, or as owner, manager,
advisor, principal, agent, partner, employee consultant, director, officer,
stockholder or other proprietor owning more than a five percent (5%)
interest, in any firm, corporation, partnership or other organization which
is in the business of manufacturing, selling or distributing products in
competition with the products of the Company.  In case of any such ownership
or participation, Executive shall furnish a detailed statement thereof to the
Board of Directors of the Company, and, as from time to time requested by
said Board, resubmit for approval a detailed statement thereof, which
statement may be approved by said Board as not constituting such a violation
or conflict, and in the event said Board determines that such violation or
conflict exists, Executive shall immediately divest himself of such ownership
or participation (or of representing or promoting others engaged in any such
business).  It is intended and agreed that during the term of this Agreement,
Executive will not knowingly perform any act which may confer any competitive
benefit or advantage upon any enterprise competing with the Company or any
successor.

       (b)    Upon the termination of the Executive 's employment with the
Company within the terms of Section 7(a) and for a period of eighteen (18)
months thereafter, Executive agrees that he shall not, on his own behalf, or
as owner, manager, advisor, principal, agent, partner, employee consultant,
director, officer, stockholder or other proprietor owning more than a five
percent (5%) interest of any business entity, or otherwise, in any territory
in which the Company is actively engaged in business: (i) open or operate any
business which is in competition with any business of the Company, (ii) act
as an employee, agent, advisor or consultant of any competitor of the
Company, (iii)  take any action to or do anything reasonably intended to
divert business from the Company or influence or attempt to influence any
existing customers of the Company to cease doing business with the Company or
to alter its business relationship with the Company, or (iv) take any action
or do anything reasonably intended to influence any suppliers of the Company
to cease doing business with the Company or to alter its business
relationship with the Company.  Executive further covenants and agrees that
he will not for himself or on behalf of any other person, partnership, firm,
association or corporation in any territory served by the Company, directly
or indirectly solicit or accept business from any of the Company's existing
customers for the purchase or sale of products or services of a like kind to
those sold or provided the Company. The foregoing covenant shall not be
deemed to prohibit Executive from acquiring an investment not more than one
percent (1%) of the capital stock of a competing business, whose stock is
traded on a national securities exchange or through the automated quotation
system of a registered securities association.

       (c)    While employed by the Company and upon the termination of the
Executive's employment with the Company within the terms of Section 7(a) and
for a period of eighteen (18) months thereafter, Executive agrees that he
shall not either directly solicit, induce, attempt to hire, recruit,
encourage, take away, hire any employee of the Company or cause any employee
of the Company to leave his or her employment either for Executive or for any
other entity or person.

       (d)    Executive represents that he (i) is familiar with the foregoing
covenants not to compete and not to directly solicit, and (ii) is fully aware
of his obligations hereunder, including, without limitation, the
reasonableness of the length of time, scope and geographic coverage of these
covenants. Executive agrees that the provisions of this Section 8 contain
restrictions that are not greater than necessary to protect the interests of
the Company.  In the event of the breach or threatened breach by

                                                                             5
<PAGE>

Executive of this Section 8, the Company, in addition to all other remedies
available to it at law or in equity, will be entitled to seek injunctive
relief and/or specific performance to enforce this Section 8.

       (e)    Company will respond within 14 days to any written request by
Executive to exclude a particular company or business entity from the scope
of this Section 8.  Company will not unreasonably deny such a request.  The
parties agree that a passive financial investment by Executive in a third
party will not constitute competition within the scope of this Section 8.

EXHIBIT A

       In consideration for Executive accepting the benefits under his
Executive Officer Severance Agreement dated November 30, 1999, Executive
agrees to release Company of all claims arising from or relating to his
employment as set forth below.

       Executive hereby forever waives for himself, his attorneys, heirs,
executors, administrators, successors and assigns any claim against Company,
including its subsidiaries, affiliates, insurers, shareholders, officers,
directors and employees (the "Parties Released"), for any action, loss,
expense or any damages arising from any occurrence from the beginning of time
until the date of the signing of this Agreement and arising or in any way
resulting from Executive's employment with Company or the termination
thereof.  The only exceptions to the above waiver are claims by Employee
under any worker's compensation or unemployment statutes and any right
arising under this Agreement.  Employee represents that he has no current
intention to assert any claim on any basis against the Parties Released.
Company releases its claims on intellectual property created by Employee
after the date of execution of this Agreement.

       EXECUTIVE ACKNOWLEDGES THAT HE HAS BEEN GIVEN AT LEAST TWENTY-ONE (21)
DAYS WITHIN WHICH TO CONSIDER SIGNING THIS RELEASE. EXECUTIVE MAY REVOKE THIS
AGREEMENT BY WRITTEN NOTICE TO COMPANY WITHIN SEVEN DAYS FOLLOWING ITS
EXECUTION.  THIS RELEASE SHALL NOT BECOME EFFECTIVE AND BINDING UNTIL SUCH
PERIOD HAS EXPIRED.  EXECUTIVE WILL RETURN ALL CONSIDERATION AND BENEFITS
PROVIDED IN CONNECTION WITH THE GRANTING OF THIS RELEASE IF HE REVOKES THE
RELEASE.

       In the event of breach of this Agreement by Company, Executive's
exclusive remedy for such breach shall be limited to the enforcement of the
terms of this Agreement.
