ABGENIX, INC.

 

CHANGE OF CONTROL
SEVERANCE AGREEMENT

 

 

This Change of Control Severance Agreement (the “Agreement”) is made
and entered into effective as of
                                        ,                    
(the “Effective Date”), by and between 
                                            
(the “Employee”) and Abgenix, Inc., a Delaware corporation (the
“Company”).  Certain capitalized terms
used in this Agreement are defined in Section 1 below.

 

R E C I T A L S

 

A.                                   It
is expected that the Company from time to time will consider the possibility of
a Change of Control.  The Board of
Directors of the Company (the “Board”) recognizes that such consideration can
be a distraction to the Employee and can cause the Employee to consider alternative
employment opportunities.

 

B.                                     The
Board believes that it is in the best interests of the Company and its
shareholders to provide the Employee with an incentive to continue his
employment and to maximize the value of the Company upon a Change of Control
for the benefit of its shareholders.

 

C.                                     In
order to provide the Employee with enhanced financial security and sufficient
encouragement to remain with the Company notwithstanding the possibility of a
Change of Control, the Board believes that it is imperative to provide the
Employee with certain severance benefits upon the Employee’s termination of
employment following a Change of Control.

 

AGREEMENT

 

In consideration of the mutual covenants herein contained and the
continued employment of Employee by the Company, the parties agree as follows:

Company with any other corporation, other than a merger or consolidation which

the Company or such surviving entity outstanding immediately after such merger

(iii)                                                     any

Securities Exchange Act of 1934, as amended) becoming the “beneficial owner”
(as defined in Rule 13d-3 under said Act), directly or indirectly, of

(iv)                                                    a

2.                                       Term

Agreement have been satisfied.

 

3.                                       At-Will
Employment.  The Company and the
Employee acknowledge that the Employee’s employment is and shall continue to be
at-will, as defined under applicable law. 
If the Employee’s employment terminates for any reason, the Employee
shall not be entitled to any payments, benefits, damages, awards or
compensation other than as provided by this Agreement, or as may otherwise be
established under the Company’s then existing employee benefit plans or
policies at the time of termination.

 

4.                                       Change
of Control and Severance Benefits.

 

(a)                                  Termination
Following A Change of Control.

 

(i)                                                           Severance
Payments.  If the Employee’s
employment with the Company terminates as a result of an Involuntary
Termination at any time within twenty four (24) months after a Change of
Control, then the Employee shall be entitled to receive continuing payments of
severance pay during the Compensation Continuation Period at a rate equal to
one hundred (100)% of the Employee’s base salary and target bonus (as in effect
immediately prior to the Change of Control). 
Such severance payments shall be paid bi-weekly in accordance with the
Company’s normal payroll practices. In addition, during the Compensation
Continuation Period, the Company shall continue to make available to the
Employee and Employee’s spouse and dependents covered under any group health
plans or life insurance plans of the Company on the date of such termination of
employment, all group health, life and other similar insurance plans in which
Employee or such Covered Dependents participate on the date of the Employee’s
termination.

 

(ii)                                                        Option
Acceleration.  If the Employee’s
employment with the Company terminates as a result of an Involuntary Termination
at any time within twenty four (24) months after a Change of Control, then each
option granted to the Employee by the Company (the “Options”) shall immediately
become vested and exercisable in full.

 

(iii)                                                     Other
Termination.  If the Employee’s
employment with the Company terminates other than as a result of an Involuntary
Termination at any time within twenty four (24) months after a Change of
Control, then the Employee shall not be entitled to receive severance or other
benefits hereunder, but may be eligible for those benefits (if any) as may then
be established under the Company’s then existing severance and benefits plans
and policies at the time of such termination.

 

(b)                                 Termination
Apart from a Change of Control.  If
the Employee’s employment with the Company terminates for any or no reason
other than within twenty four (24) months following a Change of Control, then
the Employee shall not be entitled to receive severance or other benefits
hereunder, but may be eligible for those benefits (if any) as may then be
established under the Company’s then existing severance and benefits plans and
policies at the time of such termination.

 

(c)                                  Accrued
Wages and Vacation; Expenses. 
Without regard to the reason for, or the timing of, Employee’s
termination of employment:  (i) the
Company shall pay the Employee any unpaid base salary due for periods prior to
the date of termination; (ii) the Company shall pay the 

 

3

 

Employee
all of the Employee’s accrued and unused vacation through the date of
termination; and (iii) following submission of proper expense reports by
the Employee, the Company shall reimburse the Employee for all expenses
reasonably and necessarily incurred by the Employee in connection with the business
of the Company prior to the date of termination.  These payments shall be made promptly upon termination and within
the period of time mandated by law.

 

5.                                       Golden
Parachute Excise Tax Gross-Up.  In
the event that the severance and other benefits provided for in this Agreement
or otherwise payable to Employee constitute “excess parachute payments” within
the meaning of Section 280G of the Internal Revenue Code of 1986, as amended
(the “Code”), and will be subject to the excise tax imposed by Section 4999 of
the Code (the “Excise Tax”), then Employee shall receive (i) a payment
from the Company sufficient to pay the Excise Tax, and (ii) an additional
payment from the Company sufficient to pay the Excise Tax arising from the
payments made by the Company to Employee pursuant to this sentence.  Unless the Company and Employee otherwise
agree in writing, the determination of Employee’s Excise Tax liability and the
amount required to be paid under this Section 5 shall be made in writing
by the Company’s independent public accountants (the “Accountants”).  In the event that the Excise Tax incurred by
Employee is determined by the Internal Revenue Service to be greater or lesser
than the amount determined by the Accountants, the Company and Employee agree
to promptly make such additional payment, including interest and any tax
penalties, to the other party as the Accountants reasonably determine is
appropriate to ensure that the net economic effect to Employee under this
Section 5, on an after-tax basis, is as if the Excise Tax did not apply to
Employee.  For purposes of making the
calculations required by this Section 5, the Accountants may make
reasonable assumptions and approximations concerning applicable taxes and may
rely on reasonable, good faith interpretations of the Code.  The Company and Employee shall furnish to
the Accountants such information and documents as the Accountants may
reasonably request in order to make a determination under this Section.  The Company shall bear all costs the
Accountants may reasonably incur in connection with any calculations
contemplated by this Section 5.

 

                                                The
gross-up payment to which Employee is entitled hereunder shall be paid by the
Company to Employee, in cash and in full, not later than thirty (30) calendar
days following the date Employee becomes subject to the Excise Tax.

 

6.                                       Successors.

 

(a)                                  Company’s
Successors.  Any successor to the
Company (whether direct or indirect and whether by purchase, lease, merger,
consolidation, liquidation or otherwise) to all or substantially all of the
Company’s business and/or assets shall assume the Company’s obligations under
this Agreement and agree expressly to perform the Company’s obligations under
this Agreement in the same manner and to the same extent as the Company would be
required to perform such obligations in the absence of a succession.  For all purposes under this Agreement, the
term “Company” shall include any successor to the Company’s business and/or
assets which executes and delivers the assumption agreement described in this
subsection (a) or which becomes bound by the terms of this Agreement by
operation of law.

 

(b)                                 Employee’s
Successors.    Without the written
consent of the Company, Employee shall not assign or transfer this Agreement or
any right or obligation under this Agreement to any other person or entity.
Notwithstanding the foregoing, the terms of this Agreement and all

 

4

 

rights
of Employee hereunder shall inure to the benefit of, and be enforceable by,
Employee’s personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees.

 

7.                                       Notices.

 

(a)                                  General.  Notices and all other communications
contemplated by this Agreement shall be in writing and shall be deemed to have
been duly given when personally delivered or when mailed by U.S. registered or
certified mail, return receipt requested and postage prepaid.  In the case of the Employee, mailed notices
shall be addressed to him at the home address that he most recently
communicated to the Company in writing. 
In the case of the Company, mailed notices shall be addressed to its
corporate headquarters, and all notices shall be directed to the attention of
its Secretary.

 

(b)                                 Notice
of Termination.  Any termination by
the Company for Cause or by the Employee as a result of a voluntary resignation
or an Involuntary Termination shall be communicated by a notice of termination
to the other party hereto given in accordance with this Section.  Such notice shall indicate the specific
termination provision in this Agreement relied upon, shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination under the provision so indicated. 
The failure by the Employee to include in the notice any fact or
circumstance which contributes to a showing of Involuntary Termination shall
not waive any right of the Employee hereunder or preclude the Employee from
asserting such fact or circumstance in enforcing his rights hereunder.

 

8.                                       Arbitration.

 

(a)                                  Except
as provided in Section 8(d) below, any dispute or controversy arising out
of, relating to, or in connection with this Agreement, or the interpretation,
validity, construction, performance, breach, or termination thereof, shall be
settled by binding arbitration to be held in Palo Alto, California, in
accordance with the National Rules for the Resolution of Employment Disputes
then in effect of the American Arbitration Association (the “Rules”).  The arbitrator may grant injunctions or other
relief in such dispute or controversy. 
The decision of the arbitrator shall be final, conclusive and binding on
the parties to the arbitration. 
Judgment may be entered on the arbitrator’s decision in any court having
jurisdiction.

 

(b)                                 The
arbitrator(s) shall apply California law to the merits of any dispute or claim,
without reference to conflicts of law rules. 
The arbitration proceedings shall be governed by federal arbitration law
and by the Rules, without reference to state arbitration law.  Employee hereby consents to the personal
jurisdiction of the state and federal courts located in California for any
action or proceeding arising from or relating to this Agreement or relating to
any arbitration in which the parties are participants.

 

(c)                                  Employee
understands that nothing in this Section modifies Employee’s at-will employment
status.  Either Employee or the Company
can terminate the employment relationship at any time, with or without cause.

AMENDED AND RESTATED
CHANGE OF CONTROL SEVERANCE AGREEMENT

 

 

This Change of Control Severance Agreement (the “Agreement”) is made
and entered into effective as of April 24, 2003 (the “Effective Date”), by and
between Raymond M. Withy, Ph.D. (the “Employee”) and Abgenix, Inc., a Delaware
corporation (the “Company”).  Certain
capitalized terms used in this Agreement are defined in Section 1 below.

 

R E C I T A L S

 

A.            It is expected that
the Company from time to time will consider the possibility of a Change of
Control.  The Board of Directors of the
Company (the “Board”) recognizes that such consideration can be a distraction
to the Employee and can cause the Employee to consider alternative employment
opportunities.

 

B.            The Board believes
that it is in the best interests of the Company and its shareholders to provide
the Employee with an incentive to continue his employment and to maximize the
value of the Company upon a Change of Control for the benefit of its
shareholders.

 

C.            In order to provide
the Employee with enhanced financial security and sufficient encouragement to
remain with the Company notwithstanding the possibility of a Change of Control,
the Board believes that it is imperative to provide the Employee with certain severance
benefits upon the Employee’s termination of employment following a Change of
Control.

 

D.            Dr. Withy succeeded
Mr. Greer as Chief Executive Officer of the Company in 2002 and the Board
believes that the Change of Control Severance Agreement between Dr. Withy and
the Company, dated July 1, 1999, should be amended to reflect Dr. Withy’s
current position by extending the Compensation Continuation Period.

 

AGREEMENT

 

In consideration of the mutual covenants herein contained and the
continued employment of Employee by the Company, the parties agree as follows:

 

1.             Definition

personal enrichment of the Employee, (ii) Employee’s conviction of a
felony which the Board reasonably believes has had or will have a material detrimental
effect on the Company’s reputation or business, (iii) a willful act by the
Employee which constitutes misconduct and is injurious to the Company, and
(iv) continued willful violations by the Employee of the Employee’s

performed his duties.

 

(b)           Change
of Control.  “Change of Control”
shall mean the occurrence of any of the following events:

 

(i)              the approval by shareholders of
the Company of a merger or consolidation of the Company with any other

of the total voting power represented by the voting securities of the Company
or such surviving entity outstanding immediately after such merger or
consolidation;

within twenty four (24) months after a Change of Control and ending with the
date twenty-four (24) months following the date of the Employee’s termination.

 

(d)           Involuntary
Termination.  “Involuntary
Termination” shall mean (i) without the Employee’s express written
consent, a significant reduction of the Employee’s duties, position or
responsibilities relative to the Employee’s duties, position or
responsibilities in effect immediately prior to such reduction, or the removal
of the Employee from such position, duties and responsibilities, unless the
Employee is provided with comparable duties,

(ii) without the Employee’s express written consent, a substantial reduction,
without good business reasons, of the facilities and perquisites (including

reduction; (iii) a reduction by the Company of the Employee’s base salary
or target bonus as in effect immediately prior to such reduction; (iv) a

the Employee’s express written consent, the relocation of the Employee to a
facility or a location more than thirty-five (35) miles from his current
location; (vi) any purported termination of the Employee by the Company
which is not effected for Cause or for which the grounds relied upon are not
valid; or (vii) the failure of the Company to obtain the assumption of
this Agreement by any successors contemplated in Section 6 below.

 

2.             Term
of Agreement.  This Agreement shall
terminate upon the date that all obligations of the parties hereto under this
Agreement have been satisfied.

 

3.             At-Will
Employment.  The Company and the
Employee acknowledge that the Employee’s employment is and shall continue to be
at-will, as defined under applicable law. 
If the Employee’s employment terminates for any reason, the Employee
shall not be entitled to any payments, benefits, damages, awards or
compensation other than as provided by this Agreement, or as may otherwise be
established under the Company’s then existing employee benefit plans or
policies at the time of termination.

 

4.             Change
of Control and Severance Benefits.

 

(a)           Termination
Following A Change of Control.

 

(i)              Severance Payments.  If the Employee’s employment with the
Company terminates as a result of an Involuntary Termination at any time within
twenty four (24) months after a Change of Control, then the Employee shall be
entitled to receive continuing payments of severance pay during the
Compensation Continuation Period at a rate equal to one hundred (100)% of the
Employee’s base salary and target bonus (as in effect immediately prior to the
Change of Control).  Such severance
payments shall be paid bi-weekly in accordance with the Company’s normal payroll
practices. In addition, during the Compensation Continuation Period, the
Company shall continue to make available to the Employee and Employee’s spouse
and dependents covered under any group health plans or life insurance plans of
the Company on the date of such termination of employment, all group health,
life and other similar insurance plans in which Employee or such Covered
Dependents participate on the date of the Employee’s termination.

 

(ii)             Option Acceleration.  If the Employee’s employment with the
Company terminates as a result of an Involuntary Termination at any time within
twenty four (24) months after a Change of Control, then each option granted to
the Employee by the Company (the “Options”) shall immediately become vested and
exercisable in full.

 

(iii)            Other Termination.  If the Employee’s employment with the
Company terminates other than as a result of an Involuntary Termination at any
time within twenty four (24) months after a Change of Control, then the
Employee shall not be entitled to receive severance or other benefits hereunder,
but may be eligible for those benefits (if any) as may then be established
under the Company’s then existing severance and benefits plans and policies at
the time of such termination.

 

(b)           Termination
Apart from a Change of Control.  If
the Employee’s employment with the Company terminates for any or no reason
other than within twenty four (24) months following a Change of Control, then
the Employee shall not be entitled to receive severance or other

 

3

 

benefits
hereunder, but may be eligible for those benefits (if any) as may then be
established under the Company’s then existing severance and benefits plans and
policies at the time of such termination.

 

(c)           Accrued
Wages and Vacation; Expenses.  Without
regard to the reason for, or the timing of, Employee’s termination of
employment:  (i) the Company shall
pay the Employee any unpaid base salary due for periods prior to the date of
termination; (ii) the Company shall pay the Employee all of the Employee’s
accrued and unused vacation through the date of termination; and
(iii) following submission of proper expense reports by the Employee, the
Company shall reimburse the Employee for all expenses reasonably and
necessarily incurred by the Employee in connection with the business of the
Company prior to the date of termination. 
These payments shall be made promptly upon termination and within the
period of time mandated by law.

 

5.             Golden
Parachute Excise Tax Gross-Up.  In
the event that the severance and other benefits provided for in this Agreement
or otherwise payable to Employee constitute “excess parachute payments” within
the meaning of Section 280G of the Internal Revenue Code of 1986, as amended
(the “Code”), and will be subject to the excise tax imposed by Section 4999 of
the Code (the “Excise Tax”), then Employee shall receive (i) a payment
from the Company sufficient to pay the Excise Tax, and (ii) an additional
payment from the Company sufficient to pay the Excise Tax arising from the
payments made by the Company to Employee pursuant to this sentence.  Unless the Company and Employee otherwise
agree in writing, the determination of Employee’s Excise Tax liability and the
amount required to be paid under this Section 5 shall be made in writing
by the Company’s independent public accountants (the “Accountants”).  In the event that the Excise Tax incurred by
Employee is determined by the Internal Revenue Service to be greater or lesser
than the amount determined by the Accountants, the Company and Employee agree
to promptly make such additional payment, including interest and any tax
penalties, to the other party as the Accountants reasonably determine is
appropriate to ensure that the net economic effect to Employee under this
Section 5, on an after-tax basis, is as if the Excise Tax did not apply to
Employee.  For purposes of making the
calculations required by this Section 5, the Accountants may make
reasonable assumptions and approximations concerning applicable taxes and may
rely on reasonable, good faith interpretations of the Code.  The Company and Employee shall furnish to
the Accountants such information and documents as the Accountants may
reasonably request in order to make a determination under this Section.  The Company shall bear all costs the
Accountants may reasonably incur in connection with any calculations
contemplated by this Section 5.

 

                The gross-up payment to which Employee is entitled
hereunder shall be paid by the Company to Employee, in cash and in full, not
later than thirty (30) calendar days following the date Employee becomes
subject to the Excise Tax.

 

6.             Successors.

 

(a)           Company’s
Successors.  Any successor to the
Company (whether direct or indirect and whether by purchase, lease, merger,
consolidation, liquidation or otherwise) to all or substantially all of the
Company’s business and/or assets shall assume the Company’s obligations under
this Agreement and agree expressly to perform the Company’s obligations under
this Agreement in the same manner and to the same extent as the Company would
be required to perform such obligations in the absence of a succession.  For all purposes under this Agreement, the
term

 

4

 

“Company”
shall include any successor to the Company’s business and/or assets which
executes and delivers the assumption agreement described in this
subsection (a) or which becomes bound by the terms of this Agreement by
operation of law.

 

(b)           Employee’s
Successors.    Without the written
consent of the Company, Employee shall not assign or transfer this Agreement or
any right or obligation under this Agreement to any other person or entity.
Notwithstanding the foregoing, the terms of this Agreement and all rights of
Employee hereunder shall inure to the benefit of, and be enforceable by,
Employee’s personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees.

 

7.             Notices.

 

(a)           General.  Notices and all other communications
contemplated by this Agreement shall be in writing and shall be deemed to have
been duly given when personally delivered or when mailed by U.S. registered or
certified mail, return receipt requested and postage prepaid.  In the case of the Employee, mailed notices
shall be addressed to him at the home address that he most recently
communicated to the Company in writing. 
In the case of the Company, mailed notices shall be addressed to its
corporate headquarters, and all notices shall be directed to the attention of
its Secretary.

 

(b)           Notice
of Termination.  Any termination by
the Company for Cause or by the Employee as a result of a voluntary resignation
or an Involuntary Termination shall be communicated by a notice of termination
to the other party hereto given in accordance with this Section.  Such notice shall indicate the specific
termination provision in this Agreement relied upon, shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination under the provision so indicated. 
The failure by the Employee to include in the notice any fact or
circumstance which contributes to a showing of Involuntary Termination shall
not waive any right of the Employee hereunder or preclude the Employee from
asserting such fact or circumstance in enforcing his rights hereunder.

 

8.             Arbitration.

 

(a)           Except
as provided in Section 8(d) below, any dispute or controversy arising out
of, relating to, or in connection with this Agreement, or the interpretation,
validity, construction, performance, breach, or termination thereof, shall be
settled by binding arbitration to be held in Palo Alto, California, in
accordance with the National Rules for the Resolution of Employment Disputes
then in effect of the American Arbitration Association (the “Rules”).  The arbitrator may grant injunctions or
other relief in such dispute or controversy.

the parties to the arbitration.  Judgment

and by the Rules, without reference to state arbitration law.  Employee hereby consents to the personal
jurisdiction of the state and federal courts located in California for any

arbitration in which the parties are participants.

understands that nothing in this Section modifies Employee’s at-will employment
status.  Either Employee or the Company
can terminate the employment relationship at any time, with or without cause.
