Employment Agreement - MedImmune Inc. and Wayne T. Hockmeyer

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.

                          AMENDED EMPLOYMENT AGREEMENT

                  This AMENDED EMPLOYMENT  AGREEMENT,  dated as of May 31, 2000,
is by and between WAYNE T. HOCKMEYER (the  "Executive")  and MEDIMMUNE,  INC., a
Delaware corporation (the "Company").

                  WHEREAS,   the   Executive  has  entered  into  an  employment
agreement with the Employer,  dated as of November 1, 1998 (the "1998 Employment
Agreement"),  which  provides that the  Executive  will serve the Company as its
Chairman and Chief Executive Officer;

                  WHEREAS,  at a date to be determined  by the Executive  within
the next 12 months (the  "Transition  Date"),  the Executive will elect to cease
functioning as the Chief Executive Officer of the Company and will so notify the
Company's Board of Directors (the "Board"),  but will thereafter  continue to be
employed by the Company as its  Chairman of the Board and as its Chairman of the
executive  committee of the Board (the  "Executive  Committee")  for a period of
three years following the Transition Date, subject to earlier termination as set
forth below; and

                  WHEREAS,  the Company and the  Executive  wish to set forth in
this  Amended  Employment  Agreement  the terms and  conditions  upon  which the
Executive  shall be  employed  by the  Company as its  Chairman of the Board and
Chairman of the Executive Committee for such three-year period.

                  NOW,  THEREFORE,  in  consideration  of the  premises  and the
mutual  agreements  hereinafter  contained,  the  parties do hereby  agree that,
effective as of the Transition Date, the Executive will cease functioning as the
Chief Executive  Officer of the Company,  the 1998 Employment  Agreement will be
terminated with no further force or effect,  this Amended  Employment  Agreement
shall become effective and the Executive shall commence employment solely as the
Chairman of the Board and Chairman of the Executive  Committee of the Company on
the following terms and conditions:

1.  Employment.  The Company  employs the Executive,  and the Executive  accepts
employment by the Company, upon the terms and conditions  hereinafter set forth.

2. Term.  Subject to the provisions for earlier  termination as herein provided,
the employment of the Executive  hereunder will be for the period  commencing on
the Transition Date and ending on the third anniversary of such date. The period
of the Executive's  employment under this Agreement,  as it may be terminated or
extended from time to time as provided  herein,  is referred to hereafter as the
"Employment  Period."

3. Duties and Responsibilities. The Executive will be employed by the Company as
its Chairman of the Board and Chairman of the Executive Committee. The Executive
shall be an officer of the Company and shall be  responsible  for (i)  convening
meetings  of the Board  and/or  its  executive  committee,  at such times as the
Executive  deems  appropriate,  and to establish  the agendas for and to conduct
such meetings,  (ii) working in conjunction with the Chief Executive  Officer of
the Company to set the Company's  strategic  objectives,  subject to approval of
the  Board,  and  to  assess  strategic   corporate   opportunities   and  (iii)
representing  the  Company  on matters  of public  policy  and  public  affairs,
including representation at industry-level associations and conferences,  and to
represent the interests of the Company and its stockholders on political issues,
all in consultation with the Chief Executive Officer of the Company.

4. Time to be Devoted to Employment.  Except for vacation in accordance with the
Company's  policy in  effect  from time to time and  absences  due to  temporary
illness,  the  Executive  shall devote  significant  time,  attention and energy
during the Employment Period to the business of the Company,  with the amount of
such time being  determined  by the  Executive  in  consultation  with the Chief
Executive Officer of the Company.  During the Employment  Period,  the Executive
will not be engaged in any other  business  activity  which,  in the  reasonable
judgment of the Chief Executive Officer or the Board,  conflicts with the duties
of the  Executive  hereunder,  whether or not such activity is pursued for gain,
profit or other  pecuniary  advantage,  it being  understood that serving on the
board of directors of companies that are not direct competitors with the Company
does not create such a conflict.

                                       13

5. Compensation;  Reimbursement. (a) Base Salary. From the Transition Date until
the first  anniversary of the Transition Date, the Company (or, at the Company's
option, any subsidiary or affiliate thereof) will pay to the Executive an annual
base salary of $650,000,  payable semi-monthly.  Following the first anniversary
of the Transition Date, the Company (or, at the Company's option, any subsidiary
or  affiliate  thereof)  will pay to the  Executive  an  annual  base  salary of
$1,000,000,  payable  semi-monthly.  (b) Bonus.  For the calendar year 2000, the
Executive  shall be  eligible  to  receive  a cash  bonus as  determined  by the
Compensation Committee of the Board (the "Compensation Committee").  Thereafter,
it is not anticipated that the Executive would receive a bonus. (c) Benefits. In
addition to the salary and cash bonus referred to above,  the Executive shall be
entitled  during the Employment  Period to participate in such employee  benefit
plans or programs  of the  Company,  and shall be entitled to such other  fringe
benefits,  as are from time to time made  available by the Company  generally to
its senior  officers.  Except to the extent provided in the next paragraph,  the
Executive  acknowledges  and agrees  that the  Company  does not  guarantee  the
adoption or continuance of any  particular  employee  benefit plan or program or
other fringe benefit  during the Employment  Period,  and  participation  by the
Executive  in any  such  plan or  program  shall be  subject  to the  rules  and
regulations applicable thereto.

                  As the founder of the Company, the Executive shall be entitled
to  lifetime  continuation  of  Company-provided  medical  and  dental  benefits
coverage  for  himself  and his  eligible  dependants  with such  coverage to be
provided  at the same  level  and  subject  to the  same  terms  and  conditions
(including,  without limitation, any applicable co-pay obligations) as in effect
from time to time for officers of the Company  generally.  Such  coverage  shall
remain in effect for the lifetime of the  Executive and for each of his eligible
dependants  and shall  not be  affected  by any  termination  of his  employment
relationship with the Company at any time for any reason. The foregoing coverage
shall be secondary to any Medicare coverage that the Executive or his dependants
become  eligible to receive.  The  Company  may provide the  foregoing  coverage
outside the terms of the applicable  benefits plan for employees,  provided that
coverage  for  the  Executive  is  identical  and the  tax  consequences  to the
Executive are neutral.

(d) Expenses.  The Company will reimburse the Executive,  in accordance with the
practices in effect from time to time for other  officers or staff  personnel of
the Company,  for all  reasonable  and  necessary  traveling  expenses and other
disbursements  incurred by the  Executive for or on behalf of the Company in the
performance  of the  Executive's  duties  hereunder,  upon  presentation  by the
Executive to the Company of appropriate vouchers.

6. Death;  Disability.  If the Executive dies or is incapacitated or disabled by
accident,  sickness  or  otherwise,  so as to render the  Executive  mentally or
physically  incapable of performing the services required to be performed by the
Executive  under this Agreement for a period that would entitle the Executive to
qualify for  long-term  disability  benefits  under the  Company's  then-current
long-term disability insurance program or, in the absence of such a program, for
a period of 90 consecutive  days or longer (such condition being herein referred
to as a  "Disability"),  then  (i) in the  case of the  Executive's  death,  the
Executive's  employment  shall  be  deemed  to  terminate  on  the  date  of the
Executive's  death  or (ii) in the case of a  Disability,  the  Company,  at its
option,  may terminate the  employment  of the  Executive  under this  Agreement
immediately upon giving the Executive notice to that effect. Disability shall be
determined  by the Board or the Board's  designee.  In the case of a Disability,
until the Company shall have terminated the Executive's  employment hereunder in
accordance  with the  foregoing,  the  Executive  shall be  entitled  to receive
compensation  provided for herein  notwithstanding  any such  physical or mental
disability.

7.  Termination  For Cause.  The Company may, with the approval of a majority of
the Board,  terminate  the  employment  of the  Executive  hereunder at any time
during the Employment  Period for "cause" (such  termination  being  hereinafter
called a  "Termination  for  Cause")  by  giving  the  Executive  notice of such
termination,  upon the  giving  of  which  such  termination  will  take  effect
immediately.  For purposes of this Agreement,  "cause" means (i) the Executive's
willful and substantial misconduct, (ii) the Executive's repeated, after written
notice  from the  Company,  neglect  of  duties  or  failure  to act  which  can
reasonably  be expected  to affect  materially  and  adversely  the  business or
affairs  of the  Company  or any  subsidiary  or  affiliate  thereof,  (iii) the
Executive's  material breach of any of the agreements  contained in Sections 13,
14 or 15 hereof, (iv) the commission by the Executive of any material fraudulent
act with respect to the business and affairs of the Company or any subsidiary or
affiliate  thereof  or (v)  the  Executive's  conviction  of (or  plea  of  nolo
contendere to) a crime constituting a felony.

8.  Termination  Without Cause.  The Company may terminate the employment of the
Executive  hereunder  at  any  time  without  "cause"  (such  termination  being
hereinafter called a "Termination Without Cause") by giving the Executive notice
of such termination,  upon the giving of which such termination will take effect
not later than 30 days from the date such notice is given.

9.  Voluntary  Termination.  Any  termination of the employment of the Executive
hereunder,  otherwise than as a result of death or Disability, a Termination For
Cause, a Termination  Without Cause or a termination for Good Reason (as defined
below) following a Change in Control (as defined below),  will be deemed to be a
"Voluntary  Termination." A Voluntary Termination will be deemed to be effective
immediately upon such termination.

10. Effect of Termination of Employment. (a) Voluntary Termination;  Termination
For Cause. Upon the termination of the Executive's employment hereunder pursuant
to a Voluntary Termination or a Termination For Cause, neither the Executive nor
the Executive's  beneficiaries  or estate will have any further rights or claims
against the  Company  under this  Agreement  except the right to receive (i) the
unpaid portion of the base salary provided for in Section 5(a) hereof,  computed
on a pro rata basis to the date of termination,  (ii) payment of his accrued but
unpaid rights in accordance with the terms of any incentive compensation,  stock
option, retirement, employee welfare or other employee benefit plans or programs
of the Company in which the Executive is then  participating  in accordance with
Sections 5(b) and 5(c) hereof,  (iii)  reimbursement  for any expenses for which
the Executive shall not have  theretofore been reimbursed as provided in Section
5(d) hereof,  and (iv)  continuation of his rights in accordance with the second
paragraph of Section 5(c) hereof.
(b)  Termination   Without  Cause.  Upon  the  termination  of  the  Executive's
employment  as a  Termination  Without  Cause,  neither  the  Executive  nor the
Executive's  beneficiaries  or  estate  will have any  further  rights or claims
against the  Company  under this  Agreement  except the right to receive (i) the
payments  and  other  rights  provided  for in  Section  10(a)  hereof  and (ii)
severance  payments in the form of semi-monthly  payment of the Executive's base
salary (as in effect  immediately prior to such termination) and of the Pro-Rata
Bonus  Amount  (as  defined  below)  for a period  of 24  months  following  the
effective  date  of  such  termination.  For the  purposes  of  this  Agreement,
"Pro-Rata Bonus Amount" shall mean one-twenty-fourth  (1/24th) of the greater of
(a) the most recent annual cash bonus paid to the Executive prior to the date of
his termination, or (b) the average of the three most recent annual cash bonuses
paid to the Executive prior to the date of his termination.

(c) Death and Disability.  Upon the  termination of the  Executive's  employment
hereunder  as a result of death or  Disability,  neither the  Executive  nor the
Executive's  beneficiaries  or  estate  will have any  further  rights or claims
against the  Company  under this  Agreement  except the right to receive (i) the
payments  and other  rights  provided  for in  Section  10(a)  hereof and (ii) a
lump-sum  payment,  within 15 days after the effective date of such termination,
equal to the  aggregate  amount  of the  Executive's  base  salary  as in effect
immediately  prior to such termination that would be payable over a period of 12
months following the effective date of such termination.

(d)  Forfeiture  of Rights.  In the event that,  subsequent  to  termination  of
employment  hereunder,  the  Executive  (i)  breaches any of the  provisions  of
Section 13, 14 or 15 hereof or (ii) directly or indirectly  makes or facilitates
the making of any adverse public  statements or disclosures  with respect to the
business or  securities  of the Company,  all payments and benefits to which the
Executive may otherwise have been entitled  pursuant to Section 10(a),  10(b) or
11 hereof shall immediately terminate and be forfeited,  and any portion of such
amounts as may have been paid to the  Executive  shall  forthwith be returned to
the Company.

11. Change in Control Provisions.

                                       15
<PAGE>

(a) Effect of Change in Control.  In the event of a Change in Control during the
Employment  Period,  all options held by the Executive to purchase shares of the
Company's  stock  that  are  not  then  vested  and  exercisable   shall  become
immediately  and fully vested and  exercisable  as of the effective  date of the
Change in Control.

(b) Effect of Termination  Following Change in Control. In the event of a Change
in Control  during the  Employment  Period and a subsequent  termination  of the
Executive's employment,  either by the Company as a Termination Without Cause or
by the Executive for Good Reason,  whether or not such termination is during the
Employment  Period,  the Executive shall be entitled to receive (i) the payments
and other rights  provided in Section 10(a) hereof and (ii) a severance  payment
in the form a cash lump sum,  which  shall be paid within 15 days of the date of
termination, equal to the sum of the Executive's semi-monthly base salary (as in
effect  immediately prior to such termination) and the Pro-Rata Bonus Amount (as
determined  under Section 10(b) above)  multiplied by 48 (i.e.,  that would have
been  payable  on a  semi-monthly  basis  during  the 24 months  following  such
termination), but discounted to present value from the dates such payments would
be made if paid on a semi-monthly  basis for such 24-month period,  based on the
100%  short-term  Applicable  Federal Rate  (compounded  annually) under Section
1274(d) of the  Internal  Revenue  Code of 1986,  as amended  (the "Code") as in
effect at the time of payment.  In addition,  upon any such Termination  Without
Cause or for Good Reason that occurs  within six months  following the effective
date of a Change in Control,  the  Executive  shall retain the right to exercise
any options to purchase  shares of the Company's  stock until the earlier of (a)
36 months  following the date of such  termination  or (b) the expiration of the
original full term of each such option.

(c) Definition of Change in Control.  For purposes of this Agreement,  a "Change
in Control" shall be deemed to have occurred upon:
     (i) an acquisition  subsequent to the date hereof by any person,  entity or
         group (within the meaning of Section 13(d)(3) or 14(d)(2) of the
         Securities  Exchange  Act of 1934,  as  amended  (the
         "Exchange  Act")) (a  "Person"),  of beneficial  ownership  (within the
         meaning of Rule 13d-3  promulgated  under the  Exchange  Act) of 30% or
         more of either (A) the then  outstanding  shares of common stock of the
         Company  ("Common  Stock") or (B) the combined voting power of the then
         outstanding voting securities of the Company entitled to vote generally
         in  the  election  of  directors  (the   "Outstanding   Company  Voting
         Securities");  excluding,  however, the following:  (1) any acquisition
         directly from the Company,  other than an  acquisition by virtue of the
         exercise  of a  conversion  privilege  unless  the  security  being  so
         converted  was  itself  acquired  directly  from the  Company,  (2) any
         acquisition  by the  Company  and (3) any  acquisition  by an  employee
         benefit plan (or related trust) sponsored or maintained by the Company;

                                       16
<PAGE>

(ii)     a change in the composition of the Board such that during any period of
         two consecutive years,  individuals who at the beginning of such period
         constitute  the  Board,  and any new  director  (other  than a director
         designated  by a person  who has  entered  into an  agreement  with the
         Company to effect a transaction described in clause (i), (iii), or (iv)
         of this  paragraph)  whose  election  by the  Board or  nomination  for
         election by the  Company's  stockholders  was  approved by a vote of at
         least  two-thirds of the directors then still in office who either were
         directors  at  the  beginning  of  the  period  or  whose  election  or
         nomination  for election  was  previously  so  approved,  cease for any
         reason to constitute at least a majority of the members thereof;

(iii)    the  approval  by  the   stockholders  of  the  Company  of  a  merger,
         consolidation, reorganization or similar corporate transaction, whether
         or not the Company is the surviving corporation in such transaction, in
         which outstanding  shares of Common Stock are converted into (A) shares
         of stock of another  company,  other than a  conversion  into shares of
         voting common stock of the successor  corporation (or a holding company
         thereof)  representing  80% of the voting  power of all  capital  stock
         thereof  outstanding  immediately  after the merger or consolidation or
         (B) other securities (of either the Company or another company) or cash
         or other property;

(iv)     the approval by  stockholders  of the Company of the issuance of shares
         of  Common   Stock  in   connection   with  a  merger,   consolidation,
         reorganization or similar corporate  transaction in an amount in excess
         of 40% of the number of shares of Common Stock outstanding  immediately
         prior to the consummation of such transaction;

(v)      the  approval  by the  stockholders  of the  Company of (A) the sale or
         other disposition of all or substantially all of the assets of the
         Company or (B) a complete liquidation or dissolution of the Company; or
(vi)     the adoption by the Board of a resolution to the effect that any person
         has  acquired  effective  control of the  business  and  affairs of the
         Company.

(d) Good Reason  Following  Change in Control.  For purposes of this  Agreement,
termination  for "Good  Reason" shall mean  termination  by the Executive of his
employment with the Company, within six months immediately following a Change in
Control, based on:

(i)      any diminution in the Executive's  position,  title,  responsibilities
         or authority from those in effect immediately prior to such Change in
         Control; or
(ii)     the breach by the Company of any of its material obligations under
         this Agreement.

12.      Parachute Tax Indemnity

                                       17
<PAGE>

(a) If it shall be determined  that any amount paid,  distributed  or treated as
paid or distributed by the Company to or for the  Executive's  benefit  (whether
paid or payable or  distributed or  distributable  pursuant to the terms of this
Agreement or otherwise, but determined without regard to any additional payments
required under this Section 12) (a "Payment") would be subject to the excise tax
imposed by Section 4999 of the Code,  or any interest or penalties  are incurred
by the Executive with respect to such excise tax (such excise tax, together with
any such interest and penalties,  being hereinafter  collectively referred to as
the "Excise Tax"), then the Executive shall be entitled to receive an additional
payment (a  "Gross-Up  Payment")  in an amount  such that  after  payment by the
Executive  of all  federal,  state and local taxes  (including  any  interest or
penalties imposed with respect to such taxes),  including,  without  limitation,
any income taxes (and any interest and penalties  imposed with respect  thereto)
and Excise Tax imposed  upon the  Gross-Up  Payment,  the  Executive  retains an
amount of the  Gross-Up  Payment  equal to the Excise Tax  imposed  upon all the
Payments.

(b) All  determinations  required to be made under this  Section  12,  including
whether and when a Gross-Up  Payment is required and the amount of such Gross-Up
Payment and the  assumptions  to be utilized in arriving at such  determination,
shall be made by a nationally recognized accounting firm as may be designated by
the Executive (the "Accounting  Firm") which shall provide  detailed  supporting
calculations  both to the Company and the  Executive  within 15 business days of
the receipt of notice from the Executive that there has been a Payment,  or such
earlier time as is requested  by the Company.  In the event that the  Accounting
Firm is serving as  accountant  or auditor for the  individual,  entity or group
effecting the change in control,  the Executive shall appoint another nationally
recognized accounting firm to make the determinations  required hereunder (which
accounting firm shall then be referred to as the Accounting Firm hereunder). All
fees and  expenses of the  Accounting  Firm shall be borne by the  Company.  Any
Gross-Up  Payment,  as determined  pursuant to this Section 12, shall be paid by
the Company to the Executive  within five days of the receipt of the  Accounting
Firm's determination.  Any determination by the Accounting Firm shall be binding
upon the  Company  and the  Executive.  As a result  of the  uncertainty  in the
application of Section 4999 of the Code at the time of the initial determination
by the Accounting  Firm hereunder,  it is possible that Gross-Up  Payments which
will not have been made by the Company  should have been made  ("Underpayment"),
consistent with the  calculations  required to be made  hereunder.  In the event
that the Company  exhausts  its  remedies  pursuant  to this  Section 12 and the
Executive  thereafter  is  required  to make a payment  of any Excise  Tax,  the
Accounting Firm shall determine the amount of the Underpayment that has occurred
and any such  Underpayment  shall be promptly  paid by the Company to or for the
Executive's benefit.

                                       18
<PAGE>

(c) The  Executive  shall  notify  the  Company  in  writing of any claim by the
Internal  Revenue Service that, if successful,  would require the payment by the
Company of the Gross-Up  Payment.  Such  notification  shall be given as soon as
practicable  but no later then ten business days after the Executive is informed
in  writing of such claim and shall  apprise  the  Company of the nature of such
claim and the date on which such claim is  requested to be paid.  The  Executive
shall not pay such claim prior to the expiration of the 30-day period  following
the date on which it gives such notice to the Company  (or such  shorter  period
ending on the date that any payment of taxes with respect to such claim is due).
If the Company notifies the Executive in writing prior to the expiration of such
period that it desires to contest such claim, the Executive shall:

(i)      give the Company any information reasonably requested by the Company
         relating to such claim,
(ii)     take such  action  in  connection  with  contesting  such  claim as the
         Company  shall  reasonably  request  in  writing  from  time  to  time,
         including,  without  limitation,  accepting legal  representation  with
         respect  to  such  claim  by an  attorney  reasonably  selected  by the
         Company,

(iii)    cooperate with the Company in good faith in order to effectively
         contest such claim, and
(iv)     permit the Company to participate  in any  proceeding  relating to such
         claim; provided,  however, that the Company shall bear and pay directly
         all costs and expenses  (including  additional  interest and penalties)
         incurred in connection  with  such  contest  and  shall  indemnify  and
         hold  the  Executive harmless, on an after-tax  basis,  from any Excise
         Tax or income tax (including interest  and  penalties  with  respect
         thereto)  imposed  as a result  of such representation  and  payment of
         costs and  expense.  Without  limitation  on the foregoing  provisions
         of  this  Section  12,  the  Company  shall  control  all proceedings
         taken in connection with such contest and, at its sole option,  may
         pursue or forego any and all administrative appeals,  proceedings,
         hearings and conferences  with the taxing  authority in respect of such
         claim and may, at its sole option,  either  direct the  Executive to
         pay the tax claimed and sue for a refund or contest the claim in any
         permissible  manner, and the Executive agrees to prosecute such contest
         to a determination before any administrative tribunal, in a court of
         initial  jurisdiction and in one or more appellate  courts, as the
         Company shall  determine;  provided,  however,  that if the Company
         directs the Executive to pay such claim and sue for a refund,  the
         Company shall advance the amount of such payment to the Executive,  on
         an  interest-free  basis, and shall indemnify  and hold the  Executive
         harmless,  on an after-tax  basis,  from any Excise Tax or income tax
         (including  interest or penalties with respect thereto)imposed with
         respect to such advance or with respect to any imputed  income with
         respect to such advance;  and further provided that any extension of
         the statute of  limitations  relating to payment of taxes for the
         Executive's  taxable year with  respect  to which  such  contested
         amount is claimed to be due is limited solely to such  contested
         amount.  Furthermore,  the  Company's  control of the contest  shall be
         limited  to issues  with  respect to which a Gross-Up  Payment would be
         payable  hereunder  and the  Executive  shall be  entitled to settle or
         contest,  as the case may be, any other  issue  raised by the  Internal
         Revenue Service or any other taxing authority.
(d) If,  after the  Executive's  receipt of an amount  advanced  by the  Company
pursuant  to this  Section  12, the  Executive  becomes  entitled to receive any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with the  requirements of this Section 12) promptly pay to the Company
the amount of such refund  (together with any interest paid or credited  thereon
after taxes applicable thereto).  If, after the Executive's receipt of an amount
advanced by the Company  pursuant to this  Section 12, a  determination  is made
that the  Executive  shall not be entitled  to any refund  with  respect to such
claim and the Company does not notify the  Executive in writing of its intent to
contest  such  denial of refund  prior to the  expiration  of 30 days after such
determination,  then such advance shall be forgiven and shall not be required to
be repaid and the amount of such advance  shall offset,  to the extent  thereof,
the amount of Gross-Up Payment required to be paid. (e) The foregoing provisions
of this Section 12 are intended to supersede  the  provisions of Section 7(d) of
the Company's 1991 Stock Option Plan as applied to the Executive.

13.  Disclosure of  Information.  The Executive  will not, at any time during or
after the Employment Period,  disclose to any person, firm, corporation or other
business  entity,  except  as  required  by  law,  any  non-public   information
concerning  the  business,  products,  clients or affairs of the  Company or any
subsidiary or affiliate thereof for any reason or purpose  whatsoever,  nor will
the  Executive  make  use of any of such  non-public  information  for  personal
purposes or for the benefit of any person,  firm,  corporation or other business
entity  except  the  Company  or  any  subsidiary  or  affiliate  thereof.

14.  Restrictive  Covenant(a)  .  (a)  The  Executive  hereby  acknowledges  and
recognizes that,  during the Employment  Period,  the Executive will be privy to
trade secrets and confidential proprietary information critical to the Company's
business and the Executive further  acknowledges and recognizes that the Company
would find it extremely  difficult or impossible  to replace the Executive  and,
accordingly,  the Executive  agrees that, in consideration of the benefits to be
received by the Executive hereunder,  the Executive will not, from and after the
date hereof until the first  anniversary  of the  termination  of the Employment
Period (or six months after the  termination  of the  Employment  Period if such
termination is as a result of a termination  for Good Reason  following a Change
in Control),  (i) directly or indirectly engage in the development,  production,
marketing or sale of products  that compete (or, upon  commercialization,  would
compete)  with  products  of the  Company  being  developed  (so  long  as  such
development  has not  been  abandoned),  marketed  or  sold  at the  time of the
Executive's  termination (such business or activity being  hereinafter  called a
"Competing Business") whether such engagement shall be as an officer,  director,
owner,  employee,  partner,  affiliate  or other  participant  in any  Competing
Business, (ii) assist others in engaging in any Competing Business in the manner
described in the  foregoing  clause (i), or (iii) induce other  employees of the
Company or any subsidiary thereof to terminate their employment with the Company
or any subsidiary thereof or engage in any Competing  Business.  Notwithstanding
the foregoing,  the term "Competing  Business" shall not include any business or
activity that was not conducted by the Company prior to the effective  date of a
Change in Control.

(b) The  Executive  understands  that the foregoing  restrictions  may limit the
ability of the  Executive  to earn a  livelihood  in a  business  similar to the
business of the  Company,  but  nevertheless  believes  that the  Executive  has
received and will receive  sufficient  consideration  and other benefits,  as an
employee of the Company and as  otherwise  provided  hereunder,  to justify such
restrictions which, in any event (given the education, skills and ability of the
Executive),  the Executive believes would not prevent the Executive from earning
a living.

15. Company Right to Inventions. The Executive will promptly disclose, grant and
assign to the  Company,  for its sole use and benefit,  any and all  inventions,
improvements,  technical  information and suggestions relating in any way to the
business of the Company which the  Executive  may develop or acquire  during the
Employment Period (whether or not during usual working hours), together with all
patent applications, letters patent, copyrights and reissues thereof that may at
any time be granted for or upon any such  invention,  improvement  or  technical
information. In connection therewith:

(i)      the Executive shall, without charge, but at the expense of the Company,
         promptly at all times hereafter execute and deliver such  applications,
         assignments,  descriptions and other instruments as may be necessary or
         proper  in the  opinion  of the  Company  to  vest  title  to any  such
         inventions,  improvements,  technical information, patent applications,
         patents, copyrights or reissues thereof in the Company and to enable it
         to obtain and maintain the entire  right and title  thereto  throughout
         the world; and

(ii)     the Executive shall render to the Company,  at its expense (including a
         reasonable  payment for the time  involved in case the Executive is not
         then in its  employ),  all such  assistance  as it may  require  in the
         prosecution of  applications  for said patents,  copyrights or reissues
         thereof,  in the prosecution or defense of  interferences  which may be
         declared involving any said applications,  patents or copyrights and in
         any  litigation  in which the Company  may be involved  relating to any
         such patents, inventions, improvements or technical information.

16.  Enforcement.  It is the desire and intent of the  parties  hereto  that the
provisions of this Agreement be  enforceable  to the fullest extent  permissible
under  the  laws and  public  policies  applied  in each  jurisdiction  in which
enforcement is sought.  Accordingly,  to the extent that a restriction contained
in  this  Agreement  is  more  restrictive  than  permitted  by the  laws of any
jurisdiction  where this Agreement may be subject to review and  interpretation,
the terms of such  restriction,  for the purpose  only of the  operation of such
restriction in such jurisdiction, will be the maximum restriction allowed by the
laws of such  jurisdiction  and such  restriction  will be  deemed  to have been
revised accordingly herein.

17. Remedies;  Survival(a) . (a) The Executive acknowledges and understands that
the provisions of the covenants  contained in Sections 13, 14 and 15 hereof, the
violation of which cannot be accurately  compensated for in damages by an action
at law,  are of  crucial  importance  to the  Company,  and that the  breach  or
threatened  breach of the provisions of this  Agreement  would cause the Company
irreparable harm. In the event of a breach or threatened breach by the Executive
of the  provisions of Section 13, 14 or 15 hereof,  the Company will be entitled
to an injunction  restraining  the Executive  from such breach.  Nothing  herein
contained will be construed as  prohibiting  the Company from pursuing any other
remedies available for any breach or threatened breach of this Agreement.

this Agreement until, by their terms, such provisions are no longer operative.
