provide consulting services hereunder is terminated by the Company without Cause
or by Dr. Roth for Good Reason, the Company will pay to Dr. Roth, if not
previously paid, all the amounts described in Section 4.4 at the times therein
specified (notwithstanding the termination of his retention).

SECTION 6. Restrictive Covenants; Remedies.

         6.1. Restrictive Covenants. In consideration of the payments and
benefits provided under this Agreement, Dr. Roth covenants that, during the
Restricted Period, he will not (except in his capacity as a consultant of the
Company) do any of the following, directly or indirectly, anywhere in the world:

              6.1.1. engage or participate in any business competitive with the
Business (as defined below);

              6.1.2. become interested in (as owner, stockholder, lender,
partner, co-venturer, director, officer, employee, agent or consultant) any
person, firm, corporation, association or other entity engaged in any business
competitive with the Business. Notwithstanding the foregoing, Dr. Roth may hold
up to 4.9% of the outstanding securities of any class of any publicly-traded
securities of any company;

              6.1.3. engage in any business, or solicit or call on any customer,
supplier, licensor, licensee, contractor, agent, representative, advisor,
strategic partner, distributor or other person with whom the Company shall have
dealt or any prospective customer, supplier, licensor, licensee, contractor,
agent, representative, advisor, strategic partner, distributor or other person
that the Company shall have identified and solicited at any time during Dr.
Roth's employment or retention by the Company for a purpose competitive with the
Business;

              6.1.4. influence or attempt to influence any employee, consultant,
customer, supplier, licensor, licensee, contractor, agent, representative,

have any other person or entity employ or retain) any person who has been
employed or retained by the Company within the 12 months preceding the
application of this provision to that person.

         6.2. Acknowledgements. Dr. Roth acknowledges that the Restrictive
Covenants are reasonable and necessary to protect the legitimate interests of
the Company and its affiliates and that the duration and geographic scope of the
Restrictive Covenants are reasonable given the nature of this Agreement and Dr.
Roth's relationship with the Company. Dr. Roth further acknowledges that the
Restrictive Covenants are included herein in order to induce the Company to
engage Dr. Roth pursuant to this Agreement and that the Company would not have
entered into this Agreement or otherwise retained Dr. Roth as a consultant in
the absence of the Restrictive Covenants.

                                       4


         6.3. Remedies and Enforcement Upon Breach.

              6.3.1. Specific Enforcement. Dr. Roth acknowledges that any breach
by him, willfully or otherwise, of the Restrictive Covenants will cause
continuing and irreparable injury to the Company for which monetary damages
would not be an adequate remedy. Dr. Roth will not, in any action or proceeding
to enforce any of the provisions of this Section 6, assert the claim or defense
that such an adequate remedy at law exists. In the event of any such breach by
Dr. Roth, the Company will have the right to enforce the Restrictive Covenants
by seeking injunctive or other relief in any court, without any requirement that
a bond or other security be posted, and this Section 6.3 will not in any way
limit remedies of law or in equity otherwise available to the Company.

         6.4. Termination of Payments and Vesting Service. If Dr. Roth breaches
Section 6.1 in any respect, then (a) he will not be entitled to any further
payments under this Agreement, (b) he will immediately cease to treated as
continuing in the service of the Company for purposes of vesting and expiration
of his Company stock options, and (c) all of his entitlements under this
Agreement will cease.

         6.5. Extension of Restricted Period. If Dr. Roth breaches Section 6.1
in any respect, the Restricted Period will be extended for a period equal to the
period that Dr. Roth was in breach.

         6.6. Accounting. If Dr. Roth breaches any of the Restrictive Covenants,
the Company will have the right and remedy to require Dr. Roth to account for
and pay over to the Company all compensation, profits, monies, accruals,
increments or other benefits derived or received by Dr. Roth as the result of
such breach. This right and remedy will be in addition to, and not in lieu of,
any other rights and remedies available to the Company under law or in equity.

         6.7. Judicial Modification. If any court determines that any of the
Restrictive Covenants, or any part thereof, is unenforceable because of the
duration or geographical scope of such provision, such court will have the power
to modify such provision and, in its modified form, such provision will then be
enforceable.

         6.8. Enforceability. If any court holds the Restrictive Covenants
unenforceable by reason of their breadth or scope or otherwise, it is the
intention of the parties hereto that such determination not bar or in any way
affect the right of the Company to the relief provided above in the courts of
any other jurisdiction within the geographic scope of such Restrictive
Covenants.

         6.9. Disclosure of Restrictive Covenants. Dr. Roth agrees to disclose
the existence and terms of the Restrictive Covenants to any entity to whom Dr.
Roth provides services during the Restricted Period.

SECTION 7. Non-Competition Agreement. At any time before March 29, 2003, Dr.
Roth, at his option, may execute the Non-Competition Agreement and become
entitled to the consideration therein provided. The Company acknowledges and
agrees that this offer to enter into the Non-Competition Agreement will remain
open until March 28, 2003 (and, if not accepted by that time, will then
terminate).

all his rights under this Agreement, (b) he has no entitlement under any other
employment, severance or similar arrangement maintained by the Company, and (c)
except as otherwise provided specifically in the Non-Competition Agreement (if
executed by Dr. Roth) or this Agreement, the Company does not and will not have
any other liability or obligation to him in respect of his employment by or
other service to the Company.

SECTION 9. Claims.

conducted by the Equal Employment Opportunity Commission (or similar state
agency); provided, however, that any claims by Dr. Roth for personal relief in
connection with such a charge or investigation (such as reinstatement or
monetary damages) would be barred.

Agreement during those seven days by providing written notice of revocation to
the Company.

the Company and its affiliates and that the duration and geographic scope of the
Restrictive Covenants are reasonable given the nature of this Agreement and Dr.
Roth's relationship with the Company. Dr. Roth further acknowledges that the
Restrictive Covenants are included herein in order to induce the Company to make
the payments provided for herein and that the Company would not have entered
into this Agreement in the absence of the Restrictive Covenants.

SECTION 5. Remedies and Enforcement Upon Breach.

         5.1. Specific Enforcement. Dr. Roth acknowledges that any breach by
him, willfully or otherwise, of the Restrictive Covenants will cause continuing
and irreparable injury to the Company for which monetary damages would not be an
adequate remedy. Dr. Roth will not, in any action or proceeding to enforce any
of the provisions of this Agreement, assert the claim or defense that such an
adequate remedy at law exists. In the event of any such breach by Dr. Roth, the
Company will have the right to enforce the Restrictive Covenants by seeking
injunctive or other relief in any court, without any requirement that a bond or
other security be posted, and this Agreement will not in any way limit remedies
of law or in equity otherwise available to the Company.

         5.2. Termination of Payments and Vesting Service. If Dr. Roth breaches
Section 3 in any respect, then (a) he will not be entitled to any further
payments under this Agreement, (b) he will immediately cease to treated as
continuing in the service of the Company for purposes of vesting and expiration
of his Company stock options, and (c) all of his entitlements under this
Agreement will cease.

         5.3. Extension of Restricted Period. If Dr. Roth breaches Section 3 in
any respect, the Restricted Period will be extended for a period equal to the
period that Dr. Roth was in breach.

         5.4. Accounting. If Dr. Roth breaches any of the Restrictive Covenants,
the Company will have the right and remedy to require Dr. Roth to account for
and pay over to the Company all compensation, profits, monies, accruals,
increments or other benefits derived or received by Dr. Roth as the result of
such breach. This right and remedy will be in addition to, and not in lieu of,
any other rights and remedies available to the Company under law or in equity.

         5.5. Judicial Modification. If any court determines that any of the
Restrictive Covenants, or any part thereof, is unenforceable because of the
duration or geographical scope of such provision, such court will have the power
to modify such provision and, in its modified form, such provision will then be
enforceable.

         5.6. Enforceability. If any court holds the Restrictive Covenants
unenforceable by reason of their breadth or scope or otherwise, it is the
intention of the parties hereto that such determination not bar or in any way
affect the right of the Company to the relief provided above in the courts of
any other jurisdiction within the geographic scope of such Restrictive
Covenants.

                                       3
