           5.3   For the purposes of this Agreement, a "Change in Control" of
the Company  shall mean and be  deemed to have  occurred if (a) any "person" (as
such term is used in Sections 13(d) and 14(d) of the Securities  Exchange Act of
1934 as  amended  (Exchange Act))  is  or  becomes  the  "beneficial  owner" (as
defined  in  Rule  13d-3  under  the  Exchange Act), directly  or indirectly, of
securities of the Company  representing 50% or more of the combined voting power
of the Company's then outstanding securities;  (b) at any time a majority of the
directors of the Company are persons who were not nominated  for election by the
Board;  (c) the stockholders  of the Company  approve a merger or  consolidation
of the Company with any other  corporation, other than a merger or consolidation
which  would  result in  the  voting  securities   of  the  Company  outstanding
immediately   prior  thereto  continuing  to  represent  (either  by   remaining
outstanding  or  by  being converted  into voting  securities of  the  surviving
entity) at least 50% of the combined  voting power of the  voting  securities of
the Company or such surviving entity outstanding immediately  after such  merger
or  consolidation;  (d) the Company shall  sell or otherwise  dispose of, in one
transaction  or a series of related  transactions, assets aggregating  more than
50% of the  assets of the Company  and  its  subsidiaries  consolidated;  or (e)
the  stockholders  of the Company  approve a plan of complete liquidation of the
Company or any agreement for the sale or  disposition  by the  Company of all or
substantially  all the Company's  assets.  At  the time of the  occurrence  of a
Change of  Control  all options to  purchase  shares  of  the Company  that have
been  granted to Employee pursuant to the  Company's  Stock Option Plans  and/or


                                       2




agreements,  but not yet vested,  will  immediately  vest  and Employee shall be
entitled to exercise such  options in accordance  with the plans and  agreements
relating to such options, provided,  however that the options  granted under the
Share Price  Appreciation Vesting  Non-Qualified  Option  Agreement  dated as of
February 4, 2000  between  Employee  and  the  Company  shall  not  vest  on  an
accelerated  basis  upon the occurrence  of  a Change of Control of  the Company
except as expressly set forth in that option  agreement.  At any time within one
(1) year after the occurrence of a Change in Control of the  Company, either the
Company or  Employee may terminate this Agreement upon at least thirty (30) days
notice.

           5.4   Employee may  terminate  this Agreement upon at least thirty
(30) days notice  upon the occurrence  of a constructive  dismissal of Employee.
For the purposes of this  Agreement,  "constructive dismissal" includes, without
limiting  the  generality  of  any  action  by  the  Company  which  constitutes
constructive dismissal,  unless consented to by Employee in writing,  any of the
following actions by the Company:

           (i)   any  material reduction  in  Employee's  positions,  duties,
                 responsibilities,   powers  or reporting relationships;

           (ii)  any reduction in the annual compensation of Employee;

           (iii) prior to the occurrence of a Change in Control of the Company,
                 any requirement to relocate to another city, state or country,
                 provided, however, that this provision shall not be applicable
                 if the principal executive offices of the Company are being
                 relocated to such city, state or country;

           (iv)  subsequent to the occurrence of a Change in Control of the
                 Company, any requirement to relocate to another city, state or
                 country; and

           (v)   any material reduction in the value of Employee's benefits
                 plans and programs, including, without limiting the generality
                 of the foregoing, bonus arrangements.

           5.5   The Company may terminate  this  Agreement  immediately  for
Employee's failure to perform her material job duties or responsibilities  which
failure could reasonably be expected to result in damage to the Company, willful
misconduct,  or the  commission of a felony by the  Employee,  in which case all
rights under this Agreement shall end as of the date of such termination.

           5.6   If this Agreement is terminated by the Company under Section
4 or Section 5.3, the Company  shall pay Employee a termination fee in an amount
equal to two (2) times the  aggregate  amount of her annual base salary plus her
targeted  annual bonus plus the annual  value of her  benefits and  perquisites.
Such  termination  fee will be paid in a lump sum within  fifteen (15) days from
the date of  termination.  If this  Agreement is  terminated  by Employee  under
Section 5.4, the Company  will pay Employee a  termination  fee equal to one (1)
times the  aggregate  amount of her annual base salary plus her targeted  annual
bonus plus the annual value of her benefits and  perquisites.  Such  termination
fee  will be paid in a lump  sum  within  fifteen  (15)  days  from  the date of
termination. In addition, if the Company terminates this Agreement under Section
4 or Employee  terminates  this Agreement  under Section 5.3 or Section 5.4, all
options to purchase  shares of the Company  and/or  stock  awards that have been
granted to Employee,  but not yet vested,  will  immediately vest on the date of
termination  and  Employee  will be entitled to exercise all options held by the
Employee  for a  period  of six (6)  months  after  the date of  termination  in
accordance  with the plans and  agreements  relating to such options,  provided,
however,  the  options  granted  under  the  Share  Price  Appreciation  Vesting


                                       3





Non-Qualified  Option  Agreement dated February 4, 2000 between Employee and the
Company shall not vest on an accelerated  basis upon  Employee's  termination of
employment except as expressly set forth in that option agreement.  If the terms
of this Section 5.6 and the terms of the plans and  agreements  relating to such
stock options and/or awards conflict, the terms of the option plans and/or award
agreements shall control.

           5.7   The Company shall be responsible for any gross-up payment
required to off-set any excise taxes placed on Employee if any payments made to
Employee under this Section 5 are considered "parachute payments" within the
meaning of Section 280g of the Internal Revenue Code.

     6.    Non-Compete and Non-Interference.

           6.1   During  the  Term  of  this  Agreement   and, if  Employee's
employment with the Company is terminated  under Section 4 or Section 5.3, for a
period  of twelve (12)  months  after  such  termination,  Employee  shall  not,
directly or  indirectly,  own,  manage,  operate,  control,  be employed  by, or
participate in the  ownership,  management,  operation or control of, a business
that  is  engaged  in  the  same  business   as  the  Company  within  any  area
constituting, during the term of Employee's employment or at the time Employee's
employment is terminated, a Relevant Area.  A "Relevant  Area"  shall be defined
for the  purposes of this Agreement as any area located  within, or within fifty
(50) miles of, the  legal  boundaries  or limits  of any city  within which  the
Company is engaged in business or in which the Company  has  publicly  announced
or  privately  disclosed to Employee  that it plans to  engage in  business. If,
within one (1) year of a Change of Control of the Company, Employee's employment
is  terminated by the Company  under Section 4 or Section 5.3 or by the Employee
under  Section 5.4, this Section shall not apply.

           6.2.  During  the Term of  this Agreement and  for a period of two
(2) years after termination of this Agreement,  Employee shall  not (i) directly
or indirectly cause or attempt to cause any  employee of  the Company or  any of
its affiliates to leave the employ of the Company or any affiliate,  (ii) in any
way  interfere with  the relationship  between  the Company and any  employee or
between an affiliate and  any employee  of the affiliate,  or (iii) interfere or
attempt to interfere  with  any transaction  in which  the Company or any of its
affiliates was involved during the Term of this Agreement.  If, within  one  (1)
year of a Change of Control of the Company,  Employee's employment is terminated
by the Company under Section 4 or Section 5.3 or by the  Employee  under Section
5.4,  this Section shall not apply.

           6.3   Employee  agrees that, because of the nature and sensitivity
of the information to which he will be privy and because of the nature and scope
of the Company's business, the restrictions contained in this Section 6 are fair
and reasonable.

     7.    Confidential Information.

           7.1   The relationship between the Company and  Employee is one of
confidence  and  trust.  This  relationship  and the rights  granted  and duties

means  any inventions,   discoveries, concepts  and  ideas,  whether  patentable


                                       4





or  not,  including,  without  limitation,  processes,  methods, formulas,   and
techniques (as well as  related  improvements  and  knowledge) that are based on
or  related to  Confidential   Information,   that  pertain  in  any  manner  to
the  Company's technology, expertise or business  and that are made or conceived
by Employee, either solely or jointly  with others,  and while  employed  by the
Company or within six (6) months thereafter,  whether  or not made or  conceived
during working  hours or with  the  use of the  Company's facilities,  materials
or personnel.

           7.3   Employee agrees that  he shall at no time during the Term of
this Agreement or at any time thereafter disclose  any Confidential  Information
to any person,  firm or  corporation  to any extent or for any reason or purpose
or use any  Confidential  Information  for any  purpose  other than the  conduct
of the Company's business.

           7.4   Any Confidential Information that is directly or  indirectly

Information then in her possession, whether prepared by him or not.

breach  by  Employee  of  any  of  the  provisions  of  Sections 6 or 7 of  this

from such breach.  Nothing herein shall be construed as prohibiting  the Company
from pursuing any other remedies for such breach or threatened breach, including
recovery of damages from Employee.

     9.    No Waiver.  A waiver by the  Company of a breach of any  provision
of this  Agreement  by Employee shall not operate or be construed as a waiver of
any subsequent or other breach by Employee.

     10.   Severability.  It is the desire and intent of the parties that the
provisions of this Agreement shall be enforced to the fullest extent permissible
under  the  laws and  public  policies  applied  in each  jurisdiction  in which
enforcement is sought.  Accordingly,  if any particular  provision or portion of
this  Agreement  shall be  adjudicated  to be  invalid  or  unenforceable,  this
Agreement  shall  be  deemed  amended  to  delete  therefrom  the  portion  thus
adjudicated  to be invalid or  unenforceable,  such  deletion to apply only with
respect to the operation of such  provision in the  particular  jurisdiction  in
which such adjudication is made.

     11.   Notices.  All communications, requests, consents and other notices
provided for in this Agreement  shall be in writing and shall be deemed given if
delivered by hand or mailed by first class mail,  postage  prepaid,  to the last
