Employment Agreement - Celgene Corp. and Sol J. Barer

Employment Forms

  • Employment Contract. Employers can customize an employment agreement that states the salary, benefits, working hours and other important provisions for their new or existing employee.
  • Consulting Agreement. Answer simple questions to build a contract with a consultant. Specify the services rendered, when payment is due, as well as IP rights.
  • Commission Agreement. Employers who compensate their sales employees based on commissions can prepare an agreement to reduce misunderstandings by specifying the base salary and how commissions are calculated.
  • Executive Employment Agreement. Companies may offer their business executives a contract that is different from the one provided to their regular employees. Executive employment agreements may be more complex because the compensation structure may include a combination of salary and commissions, provide for bonuses based on sales, stock or other financial targets, and include non-compete, confidentiality and severance provisions.
  • Sales Representative Contract. Independent sales representatives offer companies the potential to increase the sale of products or services without the burden of increasing headcount. Both parties should understand how commissions are calculated, when commissions will be paid, as well as how the representative will treat confidential information from the company and whether the representative may also sell a competing line of products or services.

right to disclose such information.

     9. Life  Insurance.  If requested by the Company,  Employee shall submit to
such  physical  examinations  and  otherwise  take such  actions and execute and

     Employee's conviction of a crime involving moral turpitude or a felony, (B)
     Employee's acts or omissions taken in bad faith and to the detriment of the

     to Employee by the Company, which demand specifically identifies the manner

     the injury to the Company, and after Employee's failure to correct such act
     or omission  within ten (10) days  following  such written  demand,  or (C)
     Employee's  breach of any material  term of this  Agreement  after  written
     demand for substantial performance is delivered to Employee by the Company,
     which  demand  specifically  identifies  the  manner in which  the  Company
     believes Employee has breached this Agreement, and after Employee's failure
     to correct such breach within ten (10) days following such written demand.

          (ii)  Employee's  death, in which case, this Agreement shall terminate
     on the date of Employee's death,  whereupon  Employee or his estate, as the
     case may be,  shall be  entitled to receive a lump sum payment in an amount
     equal to Employee's  annual base salary (at the rate in effect, or required
     to be in effect, immediately prior to the date of Employee's death) and the
     portion of  Employee's  annual  target bonus (as provided in Section  3(b))
     pro-rated  up to  Employee's  date of death  (assuming  the target has been
     met).

          (iii) Nothing contained in this Section 10(a) shall be deemed to limit
     any other  right the Company may have to  terminate  Employee's  employment
     hereunder upon any ground permitted by law.

     of  Employee's   employment,   whether  during  the  Employment  Period  or
     thereafter,  Employee shall be entitled to receive a lump sum payment in an
     amount equal to  Employee's  annual base salary (at the rate in effect,  or
     required  to be in  effect,  immediately  prior to the  date of  Employee's
     termination) and the portion of Employee's annual target bonus (as provided
     in  Section  3(b))   pro-rated  up  to  Employee's   date  of   disability,
     incapacitation or termination (assuming the target has been met).

          (v) In the event of the  Employee's  termination  for any reason under
     this Agreement or otherwise,  the Company shall pay and provide to Employee
     (in  addition  to  any  other  payments  or  benefits  payable  under  this
     Agreement):  (A) any  incurred  but  reimbursed  business  expenses for the
     period prior to the  termination  payable in accordance  with the Company's
     policies;  (B) any base  salary,  bonus,  vacation  pay or  other  deferred
     compensation  accrued  or  earned  under  law  or in  accordance  with  the
     Company's  policies  applicable  to Employee but not yet paid;  and (C) any
     other  amounts  or  benefits  due under  the  terms of the then  applicable
     employee  benefit,  equity or incentive plans of the Company  applicable to
     Employee (the "Accrued Benefits").

          (vi)  Payments of any amounts or benefits  hereunder  shall be made no
     later  than ten (10) days after  Employee's  termination  date,  other than
     benefits under a plan with the terms which do not require or permit payment
     within such ten (10) day period.

     (b) During the ninety (90) day period  prior to Change in Control or during
the one (1) year period  following a Change in Control,  Employee may  terminate
his employment by written notice to the Company within thirty (30) calendar days

          (ii) a significant  change in the nature or scope of the  authorities,
     powers,   functions,   duties  or  responsibilities  normally  attached  to
     Employee's position as President and Chief Operating Officer or as a member
     of the Board,  except in each case in connection  with the  termination  of
     Employee's  employment  for Cause or as a result of  Employee's  death,  or
     temporarily as a result of Employee's illness or other absence;

          (iii) a determination by Employee made in good faith that, as a result
     of a  Change  in  Control,  he is  unable  effectively  to  carry  out  the
     authorities,  powers,


                                       6

<PAGE>


     functions, duties or responsibilities attached to his position as President
     and Chief  Operating  Officer or as a member of the Board and the situation
     is not  remedied  within 30 calendar  days after  receipt by the Company of
     written notice from Employee of such determination;

          (iv) a  breach  by the  Company  of any  material  provision  of  this
     Agreement  (not covered by clause (i), (ii) or (iii) of this Section 10(b))
     or of any other  agreement,  which is not remedied  within 30 calendar days

     breach;

          (v) a reduction in Employee's annual base salary;

     welfare plan,  employee benefit plan,  pension plan, fringe benefit plan or
     compensation   plan  in  which  Employee  (and  eligible   dependents)  are
     participating  immediately  prior to a Change in Control,  unless  Employee
     (and  eligible  dependents)  are  permitted to  participate  in other plans
     providing Employee (and eligible dependents) with substantially  comparable
     benefits  at  no  greater   after-tax   cost  to  Employee   (and  eligible
     dependents),  or the  taking  of any  action  by the  Company  which  would
     adversely affect the Employee's (and eligible dependents)  participation in
     or reduce  Employee's  (and eligible  dependents)  benefits  under any such
     plan; or

          (viii) failure of a successor to assume this Agreement.

     An election by Employee to terminate his employment under the provisions of
this Section 10(b) shall not  constitute a breach by Employee of this  Agreement
and shall not be deemed a voluntary  termination  of  employment by Employee for
the purpose of  interpreting  the  provisions of any of the  Company's  employee
benefit plans, programs or policies.

     (c) Upon the  occurrence  of a Change in  Control  and  thereafter:  (A) if

Employee with Good Reason at any time during the period beginning on the date of
the Change in Control  and ending one (1) year after the date of such  Change in
Control,  or (B) if Employee's  employment with the Company is terminated by the
Company  without  Cause or by Employee for Good Reason  within  ninety (90) days

     within ten (10) days after the  Change in  Control)  equal to (A) three (3)
     times  Employee's  base  salary in  effect,  or  required  to be in effect,
     immediately  prior to the  Change in  Control,

     Employee within three (3) years prior to the Change in Control;

          (ii)  within  ten  (10)  days  after  such  termination  (or,  if such

     after the Change in Control) equal to the Accrued Benefits;

          (iii)  payment by the Company of the premiums for Employee  (except in

     the  occurrence  of a  Change  in  Control  or the date of  termination  of
     Employee's  employment,  under the Company's health and welfare plans which
     cover the senior  executives of the Company or materially  similar benefits
     ("Continuation  Coverage"),  subject to  Employee's  payment  of  customary
     premiums (if any) in effect prior to the Change in Control;

     Payments under (iii) above may, at the  discretion of the Company,  be made
by continuing Employee's  participation in the plan as a terminee or by covering
Employee and Employee's dependents under substitute arrangements, provided that,
notwithstanding  anything herein to the contrary,  to the extent Employee incurs
tax that Employee  would not have incurred as an active  employee as a result of
the aforementioned coverage or the benefits provided thereunder,  Employee shall
receive  from the  Company  an  additional  grossed  up  payment  in the  amount
necessary so that Employee will have no additional cost for receiving such items
or any  additional  payment.  Notwithstanding  anything  herein to the contrary,
Employee  (and his  eligible  dependents)  shall  retain  all  rights  under the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA") and

          (ii) the merger,  consolidation  or other business  combination of the
     Company (a "Transaction"),  other than (A) a Transaction involving only the
     Company  and  one  or  more  of  its  subsidiaries,  or  (B) a  Transaction
     immediately  following which the  stockholders  of the Company  immediately
     prior to the Transaction continue to have a majority of the voting power in
     the  resulting  entity  and no person  (other  than  those  covered  by the
     exceptions in (a) above) becomes the beneficial  owner of securities of the
     resulting entity  representing  more than twenty-five  percent (25%) of the
     voting power in the resulting entity;

          (iii) during any period of two (2)  consecutive  years beginning on or
     after  the  date  hereof,  the  persons  who  were  members  of  the  Board
     immediately before the beginning of such period (the "Incumbent Directors")
     ceasing (for any reason other than death) to constitute at least a majority
     of the Board or the board of  directors  of any  successor  to the Company,
     provided  that,  any  director who was not a director as of the date hereof
     shall be deemed to be an Incumbent Director if such director was elected to
     the board of directors by, or on the recommendation of or with the approval
     of, at least  two-thirds of the  directors who then  qualified as Incumbent
     Directors  either  actually or by prior  operation of the foregoing  unless
     such election,  recommendation  or approval occurs as a result of an actual
     or threatened  election  contest (as such terms are used in Rule 14a- 11 of
     Regulation  14A  promulgated  under  the  Exchange  Act  or  any  successor
     provision)  or other  actual  or  threatened  solicitation  of  proxies  or
     contests by or on behalf of a person other than a member of the Board; or

          (iv) the  approval by the  stockholders  of the Company of any plan of
     complete  liquidation of the Company or an agreement for the sale of all or
     substantially  all of the  Company's  assets  other than the sale of all or
     substantially  all of the assets of the  Company to a person or persons who
     beneficially own,  directly or indirectly,  at least fifty percent (50%) or
     more of the combined voting power of the outstanding  voting  securities of
     the Company at the time of such sale.

          (v) To the extent that  Employee is entitled to payment  under Section
     10(c) upon a Change in Control due to Employee's  termination without Cause
     or for Good  Reason  within  ninety (90) days prior to a Change in Control,
     any such payments under Section 10(c) shall be reduced by any payments made
     to  Employee  prior to a Change in Control  under  Sections  10(a)(iv)  and
     10(a)(v).

     11.  Limitation on Payments.

     (a) In the event that Employee shall become entitled to the payments and/or
benefits provided by Section 10(c) or any other amounts (whether pursuant to the
terms of this  Agreement or any other plan,  arrangement  or agreement  with the
Company,  any person whose  actions  result in a change of ownership  covered by
Section 280G(b)(2) of the Internal Revenue Code of 1986, as amended (the "Code")
or any  person  affiliated  with the  Company  or such  person) as a result of a
Change of  Control  (collectively  the  "Company  Payments"),  and such  Company
Payments  will be subject to the tax (the "Excise  Tax") imposed by Section 4999
of


                                       9

<PAGE>


the Code (and any similar tax that may  hereafter be imposed) the Company  shall
pay to Employee at the time  specified  in  subsection  (d) below an  additional
amount (the "Gross-up  Payment") such that the net amount  retained by Employee,
after  deduction  of any Excise Tax on the  Company  Payments  and any  federal,
state,  and local income or payroll tax upon the Gross-up  Payment pro vided for
by this paragraph (a), but before  deduction for any federal,  state,  and local
income or payroll  tax on the  Company  Payments,  shall be equal to the Company
Payments.  Notwithstanding  the  foregoing  provisions of this Section 11 to the
contrary,  if it shall be  determined  that  Employee  is entitled to a Gross-up
Payment,  but the Company Payments do not exceed one hundred five percent (105%)
of the greatest  amount that could be paid to Employee  such that the receipt of
Company  Payments would not give rise to any Excise Tax (the "Reduced  Amount"),
then no Gross-up Payment shall be made to Employee and the Company Payments,  in
the aggregate, shall be reduced to the Reduced Amount.

     (b) For  purposes of  determining  whether any of the Company  Payments and
Gross-up  Payments  (collectively  the "Total  Payments") will be subject to the
Excise Tax and determining the amount of such Excise Tax: (i) the Total Payments
shall  be  treated  as  "parachute  payments"  within  the  meaning  of  Section
280G(b)(2)  of the Code,  and all  "parachute  payments"  in excess of the "base
amount" (as defined under Code Section  280G(b)(3) of the Code) shall be treated
as subject  to the Excise  Tax,  unless  and except to the extent  that,  in the
opinion of the Company's  independent  certified  public  accountants  appointed
prior to any change in ownership (as defined under Code Section  280G(b)(2))  or
tax counsel selected by such accountants (the "Accountants") such Total Payments
(in whole or in part), (A) do not constitute "parachute payments," (B) represent
reasonable  compensation  for services  actually  rendered within the meaning of
Section  280G(b)(4)  of the Code" or (C) are otherwise not subject to the Excise
Tax;  and (ii) the value of any  non-cash  benefits or any  deferred  payment or
benefit shall be determined by the Accountants in accordance with the principles
of Section 280G of the Code.

     (c) For  purposes  of  determining  the  amount  of the  Gross-up  Payment,
Employee  shall be deemed to pay federal  income  taxes at the highest  marginal
rate of federal  income  taxation  in the  calendar  year in which the  Gross-up
Payment is to be made and state and local income  taxes at the highest  marginal
rate of  taxation  in the state and  locality of  Employee's  residence  for the
calendar  year in which the  Company  Payment is to be made,  net of the maximum
reduction in federal income taxes which could be obtained from deduction of such
state and local taxes if paid in such year.  In the event that the Excise Tax is
subsequently determined by the Accountants to be less than the amount taken into
account hereunder at the time the Gross-up Payment is made, Employee shall repay
to the Company,  at the time that the amount of such  reduction in Excise Tax is
finally  determined,  the portion of the prior Gross-up Payment  attributable to
such reduction  (plus the portion of the Gross-up  Payment  attributable  to the
Excise Tax and federal, state and local income tax imposed on the portion of the
Gross-up  Payment  being  repaid by  Employee  if such  repayment  results  in a
reduction  in Excise Tax or a federal,  state and local  income tax  deduction),
plus  interest on the amount of such  repayment at the rate  provided in Section
1274(b)(2)(B)  of the  Code.  Notwithstanding  the  foregoing,  in the event any
portion of the  Gross-up  Payment to be refunded to the Company has been paid to
any  federal,  state and local tax  authority,  repayment  thereof  (and related
amounts) shall not be


                                       10

<PAGE>


required  until  actual  refund  or  credit  of such  portion  has been  made to
Employee,  and  interest  payable to the Company  shall not exceed the  interest
received or credited  to Employee by such tax  authority  for the period it held
such portion.  Employee and the Company shall  mutually agree upon the course of
action to be pursued  (and the method of  allocating  the  expense  thereof)  if
Employee's claim for refund or credit is denied.

     In the event that the Excise Tax is later  determined by the Accountants or
the Internal  Revenue Service to exceed the amount taken into account  hereunder
at the time the Gross-up Payment is made (including by reason of any payment the
existence  or amount of which cannot be  determined  at the time of the Gross-up
Payment),  the Company shall make an additional  Gross-up  Payment in respect of
such excess (plus any interest or penalties payable with respect to such excess)
at the time that the amount of such excess is finally determined.

     (d) The Gross-up  Payment or portion thereof provided for in subsection (c)
above shall be paid not later than the  thirtieth  (30th) day following an event
occurring which sub jects Employee to the Excise Tax; provided, however, that if
the  amount of such  Gross-up  Payment  or  portion  thereof  cannot be  finally
determined  on or before such day, the Company shall pay to Employee on such day
an estimate,  as  determined  in good faith by the  Accountants,  of the minimum
amount of such payments and shall pay the  remainder of such payments  (together
with interest at the rate provided in Code Section  1274(b)(2)(B)  of the Code),
subject to further  payments  pursuant to subsection (c) hereof,  as soon as the
amount  thereof can  reasonably  be  determined,  but in no event later than the
ninetieth  (90th) day after the occurrence of the event  subjecting  Employee to
the Excise Tax. In the event that the amount of the estimated  payments  exceeds
the  amount  subsequently  determined  to  have  been  due,  such  excess  shall
constitute  a loan by the  Company to  Employee,  payable on the fifth (5th) day
after  demand by the Company  (together  with  interest at the rate  provided in
Section 1274(b)(2)(B) of the Code).

     (e) In the event of any controversy  with the Internal  Revenue Service (or
other taxing authority) under this Section 11, Employee shall permit the Company
to control  issues  related to this Section 11 (at its  expense),  provided that
such  issues  do not  potentially  materially  adversely  affect  Employee,  but
Employee  shall  control  any  other  issues.   In  the  event  the  issues  are
interrelated,  Employee and the Company shall in good faith  cooperate so as not
to  jeopardize  resolution  of either  issue,  but if the parties  cannot agree,
Employee shall make the final  determination  with regard to the issues.  In the
event of any  conference  with any  taxing  authority  as to the  Excise  Tax or
associated income taxes, Employee shall permit the representative of the Company
to accompany him, and Employee and his  representative  shall cooperate with the
Company and its representative.

     (f) The Company shall be responsible for all charges of the Accountants.

     12.  Successors.  In  addition to any  obligations  imposed by law upon any
successor to the Company, the Company will require any successor (whether direct
or  indirect,  by  purchase,  merger,  consolidation  or  otherwise)  to  all or
substantially  all of the  business  and/or  assets of the Company to  expressly
assume and agree in writing to perform this


                                       11

<PAGE>


Agreement  in the same manner and to the same  extent that the Company  would be
required to perform it if no such succession had taken place.

     13. Survival.  The covenants,  agreements,  representations  and warranties
contained  in or  made  pursuant  to this  Agreement  shall  survive  Employee's
termination of employment.

     14. Entire  Agreement;  Modification.  This Agreement sets forth the entire
understanding  of the  parties  with  respect  to  the  subject  matter  hereof,
supersedes all existing  agreements  between them concerning such subject matter
(including,  without limitation, the employment agreement in effect prior to the
date hereof) and may be modified only by a written  instrument  duly executed by
each party.

     15. Notices. Any notice or other communication  required or permitted to be
given  hereunder  shall be in  writing  and shall be mailed by  certified  mail,
return receipt  requested,  or delivered against receipt to the party to whom it
is to be given at the  address of such party set forth in the  preamble  to this
Agreement (or to such other address as the party shall have furnished in writing
in accordance  with the provisions of this Section 15).  Notice to the estate of
Employee  shall be  sufficient  if  addressed  to  Employee  as provided in this
Section 15. Any notice or other  communication  given by certified mail shall be
deemed given three days after the time of  certification  thereof,  except for a
notice  changing a party's  address  which shall be deemed  given at the time of
receipt thereof.

     16. Waiver. Any waiver by either party of a breach of any provision of this
Agreement  shall  not  operate  as or be  construed  to be a waiver of any other
breach  of such  provision  or of any  breach  of any  other  provision  of this
Agreement. The failure of a party to insist upon strict adherence to any term of
this  Agreement  on one or more  occasions  shall not be  considered a waiver or
deprive that party of the right  thereafter  to insist upon strict  adherence to
that term or any other term of this  Agreement.  Any waiver  must be in writing,
signed by the party giving such waiver.

     17. Binding Effect.  Employee's rights and obligations under this Agreement
shall not be transferable  by assignment or otherwise,  such rights shall not be
subject to commutation,  encumbrance or the claims of Employee's creditors,  and
any attempt to do any of the  foregoing  shall be void.  The  provisions of this
Agreement  shall be binding  upon and inure to the benefit of  Employee  and his
heirs and personal  representatives,  and shall be binding upon and inure to the
benefit of the Company and its successors and its assigns under Section 12.

     18. No Third Party Beneficiaries. This Agreement does not create, and shall
not be construed as creating,  any rights  enforceable by any person not a party
to this Agreement (except as provided in Sections 12 and 17).

     19. Legal Fees. To the fullest  extent  permitted by law, the Company shall
promptly pay upon  submission  of  statements  all legal and other  professional
fees, costs of litigation,  prejudgment interest, and other expenses incurred in
connection with any dispute


                                       12

<PAGE>


concerning payments,  benefits and other entitlements to which Employee may have
under this  Agreement;  provided,  however,  the Company  shall be reimbursed by
Employee for the fees and expenses advanced in the event Employee's claim is, in
a material  manner,  in bad faith or frivolous and the  arbitrator or court,  as
applicable,  determines  that the  reimbursement  of such fees and  expenses  is
appropriate.

     20.  Pooling of  Interests;  Severability.  In the event that the Company's
independent  public  accountants  determine in good faith that any  provision of
this  Agreement  would preclude  "pooling of interests"  accounting and provided
that the Company engages in a transaction  which utilizes "pooling of interests"
accounting, such provision shall be deemed invalid and inoperative solely to the
extent necessary to permit "pooling of interests"  transactions.  If any portion
of this Agreement is held invalid or inoperative  (including a determination  by
the Company's independent public accountants in good faith that any provision of
this Agreement  would  preclude  "pooling of interests"  accounting),  the other
provisions of this  Agreement  shall be deemed to be valid and operative and, so
far as is  reasonable  and  possible,  effect  shall  be  given  to  the  intent
manifested by the portion held valid or inoperative.

     21. No Duty to  Mitigate/No  Offset.  The Company agrees that if Employee's
employment with the Company is terminated  pursuant to this Agreement during the
term of this Agreement,  Employee shall not be required to seek other employment
or to attempt  in any way to reduce  any  amounts  payable  to  Employee  by the
Company  pursuant  to this  Agreement.  Further,  the  amount of any  payment or
benefit  provided for in this Agreement shall not be reduced by any compensation
earned by Employee or benefit  provided to Employee as the result of  employment
by another employer or otherwise. The Company's obligations to make the payments
provided  for in  this  Agreement  and  otherwise  to  perform  its  obligations
hereunder  shall  not  be  affected  by  any  circumstances,  including  without
limitation, any set-off, counterclaim,  recoupment, defense or other right which
the Company may have against Employee.  Notwithstanding the foregoing,  payments
and benefits  under the  Agreement  will cease to be paid and may be recouped by
the Company in the event Employee breaches any of the terms of Section 6, 7 or 8
hereunder.

     22.  Counterparts;  Governing  Law.  This  Agreement may be executed in any
number of  counterparts,  each of which shall be deemed an original,  but all of
which  together  shall  constitute  one and the  same  instrument.  It  shall be
governed  by and  construed  in  accordance  with the  laws of the  State of New
Jersey, without giving effect to the conflict of laws.
