                  latter date; and

                           (v) to the extent not therefore exercisable, the

<PAGE>   4
                  date of this Agreement) occurs, if the Employee's full-time
                  employment by the Company continues until that date, provided
                  that, if such Change in Control occurs less than six months
                  after the date on which the option is granted (the "Grant
                  Date"), the Employee agrees in writing (if requested to do so
                  by the Administrator) to remain in the employ of the Company
                  or a subsidiary at least through the date which is six months

                  duties, authority, reporting relationships and compensation as
                  on the day immediately preceding such Change in Control; and

                           (vi) the $26 Option, the $41 Option and the $65
                  Option shall each expire on the eighth anniversary of the
                  Commencement Date and the At-Market Option shall expire on the
                  tenth anniversary of the Commencement Date unless the
                  Employee's employment terminates before the applicable
                  foregoing expiration date, in which case each Option shall
                  expire upon such termination of employment or within such
                  period of time thereafter as the Administrator may specify;

                  (e) the business and personal use of an automobile at Company

                  (f) participation in all Company health, welfare, savings and

events to the terms and conditions of such plans as in effect from time to time.
Nothing in this paragraph (f) shall preclude the Company from amending or
terminating any such plan at any time. The plans covered by this paragraph (f)
shall not include the annual incentive or stock option plans, which are covered
by paragraphs (b) and (d) above; and

                  (g) the Company shall pay, or reimburse the Employee for, the
premiums she incurs to maintain her current medical malpractice insurance
coverage (or equivalent coverage) during the term, such premiums payable or
reimburseable by the Company in no event to exceed $15,000 per year of the term.

         5.       Termination of Employment.

                  (a) Termination by the Company without Good Cause or by the
Employee for Good Reason.

                           (i) If during the term of this Agreement the
Employee's employment with the Company is terminated by the Company without Good
Cause or is terminated by the Employee for Good Reason other than at or after
the expiration of the term of this Agreement as the same may have been extended
in accordance with the


                                       4
<PAGE>   5
provisions of paragraph 2 above, the Company, subject to compliance by the
Employee with the provisions of paragraph 6 below, relating to confidential
information, shall, as liquidated damages, and as additional consideration for
the Employee's undertakings under paragraph 6 below, (A) pay the Employee a lump
sum amount of money equal to 1.5 times the Employee's Base Salary, and (B) if
such employment termination occurs before the Retention Payment referred to in
paragraph 4(c) above has been paid to the Employee, pay the Retention Payment.

                           (ii) If the term of this Agreement as the same may
have been extended in accordance with the provisions of paragraph 2 above is not
extended or further extended because the Company gives written notice of
non-extension to the Employee as provided in paragraph 2 above, and the Company
does not have Good Cause for termination of the Employee's employment at the
time of giving such notice, then the Company, subject to fulfillment by the
Employee of her obligations under this Agreement during the balance of the term
and her compliance with the provisions of paragraph 6 below, relating to
confidential information, shall, as non-renewal compensation, and as additional
consideration for the Employee's undertakings under this Agreement including
paragraph 6 below, pay the Employee a lump sum amount of money equal to 1.0
times the Employee's Base Salary. The Company shall pay such amount upon the
expiration of the term that is in effect at the time the Company gives such
written notice of non-extension to the Employee.

                           (iii) The foregoing provisions of this paragraph 5(a)
shall be in lieu of any severance pay that may be payable under any plan or
practice of the Company.

                  (b) Termination by the Company for Good Cause or by the
Employee without Good Reason. If, during the term of this Agreement, the
Employee's employment by the Company is terminated by the Company for Good Cause
or by the Employee without Good Reason, the Employee shall not be entitled to
receive any compensation under paragraph 4 above acruing after the date of such
termination or any payment under paragraph 5(a) above. The provisions of this
paragraph 6(b) shall be in addition to, and not in lieu of, any other rights and
remedies the Company may have at law or in equity or under any other provision
of this Agreement (including without limitation paragraph 4(c) above) in respect
of such termination of employment.

                  (c) Good Cause Defined. For purposes of this Agreement, the
Company shall have "Good Cause" to terminate the Employee's employment during
the term of this Agreement if:

                           (i) the Employee fails to substantially perform her
duties hereunder for any reason or fails to devote substantially all her
business time exclusively to the affairs of the Company, and such failure is not
discontinued within a reasonable period of time, in no event to exceed 30 days,
after the Employee receives written notice from the Company of such failure; or


                                       5
<PAGE>   6
                           (ii) the Employee commits an act of dishonesty
resulting or intended to result directly or indirectly in gain or personal
enrichment at the expense of the Company; or

                           (iii) the Employee is grossly negligent or engages in
willful misconduct or insubordination in the performance of her duties
hereunder; or

                           (iv) the Employee breaches her obligations under
paragraph 6 below, relating to confidential information.

                  (d) Good Reason Defined. For purposes of this Agreement, the
Employee shall have "Good Reason" to terminate her employment during the term of
this Agreement only if:

                           (i) the Company fails to provide compensation or
benefits that the Company is obligated to provide under paragraph 4 above and
the failure is not remedied within 30 days after the Company receives written
notice from the Employee of such failure; or

                           (ii) the Company assigns the Employee duties,
responsibilities or reporting relationships not contemplated by paragraph 3
above without her consent, or limits her duties or responsibilities contemplated
by paragraph 3 above in any respect materially detrimental to her, and in either
case the situation is not remedied within 30 days after the Company receives
written notice from the Employee of the situation; or

                           (iii) she is removed from, or not elected or
reelected to, the position of President of Barr Research, or the Board, and the
Company does not have Good Cause for doing so; or

                           (iv) the Company relocates her office outside of a
forty (40) mile radius from her residence on the date of this Agreement without
her consent and the situation is not remedied within 30 days after the Company
receives written notice from the Employee of the situation.

         6. Confidential Information. The Employee agrees not to disclose,
either while in the Company's employ or at any time thereafter, to any person
not employed by the Company, or not engaged to render services to the Company,
except with the prior written consent of an authorized officer of the Company or
as necessary or appropriate for the performance of her duties hereunder, any
confidential information obtained by her while in the employ of the Company,
including, without limitation, information relating to any of the inventions,
processes, formulae, plans, devices, compilations of information, research,
methods of distribution, suppliers, customers, client relationships, marketing
strategies or trade secrets of the Company or any subsidiary thereof; provided,
however, that this provision shall not preclude the Employee from use or
disclosure of information known generally to the public or of information not
considered confidential by persons engaged in the businesses conducted by the
Company or any subsidiary thereof, or from


                                       6
<PAGE>   7
disclosure required by law or court order. The Employee also agrees that upon
leaving the Company's employ she will not take with her, without the prior
written consent of an authorized officer of the Company, and she will surrender
to the Company, any record, list, drawing, blueprint, specification or other
document or property of the Company or any subsidiary thereof, together with any
copy or reproduction thereof, mechanical or otherwise, which is of a
confidential nature relating to the Company or any subsidiary thereof, or
without limitation, relating to its or their methods of distribution, suppliers,
customers, client relationships, marketing strategies or any description of any
formulae or secret processes, or which was obtained by him or entrusted to her
during the course of her employment with the Company.

         7.       Severability

                  (a) In the event that any provision of this Agreement shall be
determined to be invalid or unenforceable for any reason, the remaining
provisions of this Agreement not so invalid or unenforceable shall be unaffected
thereby and shall remain in full force and effect to the fullest extent
permitted by law; and

                  (b) Any provision of the Agreement which may for any reason be
invalid or unenforceable in any jurisdiction shall remain in effect and be
enforceable in any jurisdiction in which such provision shall be valid and
enforceable.

         8. General Provisions.

                  (a) No right or interest to or in any payments to be made
under this Agreement shall be subject to anticipation, alienation, sale,
assignment, encumbrance, pledge, charge or hypothecation or to execution,
attachment, levy or similar process, or assignment by operation of law. All
payments to be made by the Company hereunder, including the sign-on bonus and
Retention Payment referred to in paragraph 4(c) above, shall be subject to the
withholding of such amounts as the Company may determine it is required to
withhold under the laws or regulations of any governmental authority, whether
foreign, federal, state or local.

                  (b) To the extent that the Employee acquires a right to
receive payments from the Company under this Agreement, such right shall be no
greater than the right of an unsecured general creditor of the Company. All
payments to be made hereunder shall be paid from the general funds of the
Company and no special or separate fund shall be established and no segregation
of assets shall be made to assure payment of any amount hereunder.

                  (c) This Agreement shall be governed by and construed and
enforced in accordance with the laws of the State of New York, without giving
effect to the principles of conflicts of laws of that State.
