EXHIBIT 10.32
                FORM OF CHANGE IN CONTROL EMPLOYMENT AGREEMENT
     AGREEMENT by and between PathoGenesis Corporation, a Delaware corporation
(the "Company"), and _______________________ ("Executive"), dated as of
_____________, 199___ (the "Agreement Date").
                                   Recitals
     A.   The Board of Directors of the Company (the "Board") has determined
that it is in the best interests of the Company and its shareholders to assure
that the Company will have the continued dedication of Executive,
notwithstanding the possibility, threat, or occurrence of a Change in Control
(as defined below) of the Company.
     B.   The Board believes it is imperative to diminish the inevitable
distraction of Executive by virtue of the personal uncertainties and risks
created by a pending or threatened Change in Control, to encourage Executive's
full attention and dedication to the Company, and to provide Executive with
compensation and benefits arrangements upon a Change in Control which (i) will
satisfy Executive's compensation and benefits expectations and (ii) are
competitive with those of other public corporations.

     (a)  Position and Duties.
          (i)  During the Employment Period, (A) Executive's position (including
     status, offices and titles), authority, duties and responsibilities shall
     be at least commensurate in all material respects with the most significant
     of those held or exercised by or assigned to Executive at any time during
     the 90-day period immediately preceding the Effective Date and (B)
     Executive's services shall be performed at the location where Executive was
     employed immediately preceding the Effective Date or any office or location
     less than 50 miles from such location.
          (ii) During the Employment Period, and excluding any periods of
     vacation, sick leave and disability to which Executive is entitled,
     Executive shall devote reasonable attention and time during normal business
     hours to the business and affairs of the Company and, to the extent
     necessary to discharge the responsibilities assigned to Executive
     hereunder, to use Executive's reasonable best efforts to perform faithfully
     and efficiently such responsibilities. During the Employment Period,
     Executive may (A) serve on corporate, civic or charitable boards or
     committees, (B) deliver lectures, fulfill speaking engagements or teach at
     educational institutions and (C) manage personal investments, so long as
     such activities are consistent with the policies of the Company at the
     Effective Date and do not significantly interfere with the performance of
     Executive's responsibilities (as set forth in this Agreement) as an
     employee of the Company. To the extent that any such activities have been
     conducted by Executive prior to the Effective Date and were consistent with
     the policies of the Company at the Effective Date, the continued conduct of
     such activities (or the conduct of activities similar in nature and scope
     thereto) subsequent to the Effective Date shall not thereafter be deemed to
     interfere with the performance of Executive's responsibilities to the
     Company.
     (b)  Compensation.
          (i)  Base Salary.  During the Employment Period, Executive shall
     receive an annual base salary in cash ("Annual Base Salary"), which shall
     be paid in a manner consistent with the Company's payroll practices
     immediately preceding the Effective Date at a rate at least equal to 12
     times the monthly base salary (unreduced by any salary reductions or
     deferrals pursuant to a plan maintained under Section 401(k) of the Code or
     any similar plan) paid or payable to Executive by the Company for the
     calendar month immediately preceding the month in which the Effective Date
     occurs. During the Employment Period, the Company shall review the Annual
     Base Salary at least annually and shall increase Annual Base Salary at any
     time and from time to time as shall be substantially consistent with
     increases in base salary awarded in the ordinary course of business to peer
     executives of the Company. Any increase in Annual Base Salary shall not
     serve to limit or reduce any other obligation to Executive under this
     Agreement. Annual Base Salary shall not be reduced after any such increase
     and the term "Annual Base Salary" shall refer to Annual Base Salary as so
     increased.
          (ii) Annual Bonus.  In addition to Annual Base Salary, Executive shall
     be awarded, for each fiscal year part or all of which is included in the
     Employment Period, an annual bonus (the "Annual Bonus") in cash which is at
     least equal to the greater of
                                       5
 
     (A)  the amount of annual bonus actually paid to Executive during the
     fiscal year immediately preceding the Effective Date or (B) the target
     bonus for the Executive for the fiscal year that includes the Effective
     Date (or, if not yet determined for the current fiscal year, for the
     immediately preceding fiscal year) previously determined by the Board or
     the compensation committee of the Board (in either case (A) or (B), any
     such annual bonus amount to be annualized for any fiscal year consisting of
     less than 12 full months or with respect to which Executive has been
     employed by the Company for less than 12 full months). The Company shall
     pay each such Annual Bonus in cash no later than 90 days after the end of
     the fiscal year for which the Annual Bonus is awarded, unless Executive
     shall elect to defer the receipt of such Annual Bonus.
          (iii)  Incentive, Savings and Other Plans.  In addition to Annual Base
     Salary and Annual Bonus payable as hereinabove provided, Executive shall be
     entitled to participate during the Employment Period in all incentive,
     stock option, savings and other plans and Policies applicable to peer
     executives of the Company, but in no event shall such plans and Policies
     provide Executive with incentive or other benefits opportunities, in each
     case, less favorable, in the aggregate, than the most favorable of those
     provided by the Company for Executive under such plans and Policies as in
     effect at any time during the 90-day period immediately preceding the
     Effective Date.
          (iv)   Welfare Benefit Plans.  During the Employment Period, Executive
     and/or Executive's family, as the case may be, shall be eligible to
     participate in and shall receive all benefits under welfare benefit plans
     and Policies provided by the Company and applicable to peer executives of
     the Company, but in no event shall such plans and Policies provide benefits
     which are less favorable, in the aggregate, than the most favorable of such
     plans and Policies in effect at any time during the 90-day period
     immediately preceding the Effective Date.
          (v)    Expenses.  During the Employment Period, Executive shall be
     entitled to prompt reimbursement for all reasonable expenses incurred by
     Executive in accordance with the most favorable Policies of the Company in
     effect at any time during the 90-day period immediately preceding the
     Effective Date or, if more favorable to Executive, as in effect at any time
     thereafter with respect to peer executives of the Company.
          (vi)   Fringe Benefits.  During the Employment Period, Executive shall
     be entitled to fringe benefits in accordance with the most favorable plans
     and Policies of the Company in effect at any time during the 90-day period
     immediately preceding the Effective Date or, if more favorable to
     Executive, as in effect at any time thereafter with respect to peer
     executives of the Company.
          (vii)  Office; Support Staff.  During the Employment Period, Executive
     shall be entitled to an office or offices of a size and with furnishings
     and other appointments, and to personal secretarial and other assistance,
     at least equal to the most favorable of the foregoing provided to Executive
     by the Company at any time during the 90-day period immediately preceding
     the Effective Date or, if more favorable to Executive, as provided at any
     time thereafter with respect to peer executives of the Company.
          (viii) Vacation.  During the Employment Period, Executive shall be
     entitled to paid vacation in accordance with the most favorable plans and
     Policies of the Company
                                       6
 
     as in effect at any time during the 90-day period immediately preceding the
     Effective Date or, if more favorable to Executive, as in effect at any time
     thereafter with respect to peer executives of the Company.
          (ix)   Affiliated Companies.  To the extent that, immediately prior to
     the Effective Date, Executive has been on the payroll of, and participated
     in the bonus, incentive or employee benefit plans of, an Affiliated
     Company, the references to the Company contained in Sections 2(b)(i)
     through 2(b)(viii) and elsewhere in this Agreement referring to benefits to
     which Executive may be entitled shall also refer to such Affiliated
     Company.
     3.   Termination of Employment.
          (a)  Death or Disability.  Executive's employment shall terminate
automatically upon Executive's death during the Employment Period. If the
Company determines in good faith that the Disability of Executive has occurred
during the Employment Period, it may give to Executive written notice of its
intention to terminate Executive's employment. In such event, Executive's
employment with the Company shall terminate as of the 30th day after Executive's
receipt of such notice (the "Disability Effective Date"); provided that, within
the 30 days after such receipt, Executive shall not have returned to full-time
performance of Executive's duties. "Disability" means the absence of Executive
from Executive's duties with the Company on a full-time basis for a period of
time equal to the Waiting Period as a result of incapacity due to mental or
physical illness that is determined to be total and permanent by a physician
selected by the Company or its insurers and reasonably acceptable to Executive
or Executive's legal representative. "Waiting Period" means the waiting period
under a long-term disability plan of the Company that is applicable to Executive
and satisfies the requirements of Section 2(b)(iv).
     (b)  Cause.  The Company may terminate Executive's employment for Cause
during the Employment Period. "Cause" means the occurrence of any one or more of
the following actions or failures to act as determined by the Board in its
reasonable judgment and in good faith:
          (i)    embezzlement, fraud or theft by Executive with respect to the
     property of the Company or a conviction of Executive for any felony
     involving moral turpitude or causing material harm, financial or otherwise,
     to the Company;
          (ii)   habitual neglect in the performance of Executive's significant
     duties (other than on account of incapacity due to physical or mental
     illness or Disability); or
          (iii)  a demonstrably deliberate act or failure to act of Executive,
     including a violation of the rules or policies of the Company, which causes
     a material financial or other loss, damage or injury to the property,
     reputation or employees of the Company; provided, however, that, unless
     such act or failure to act was done by Executive in bad faith or without a
     reasonable belief that Executive's act or failure to act, as the case may
     be, was in the best interest of the Company or was required by applicable
     law, such act or failure to act shall not constitute Cause if, within 20
     days after the Board or the Chief Executive Officer of the Company gives
     Executive written notice of such act or failure to act that specifically
     refers to this Section, Executive cures such act or failure to act to the
     fullest extent that it is curable;
                                       7
 
provided, however, that:
          (A)  "Cause" shall not mean (x) bad judgment or negligence other than
     habitual neglect of significant duties or (y) any act or omission in
     respect of which the Board could have properly determined that Executive
     met the applicable standard of conduct for the indemnification or
     reimbursement under the by-laws of the Company or applicable law, in each
     case as in effect at the time of such act or omission; and
          (B)  a termination of Executive's employment shall not be deemed to be
     for Cause unless each of the following conditions is satisfied:
               (1)  The Company provides Executive a written notice (a "Notice
          of Intent to Terminate") not less than 30 days prior to the Date of
          Termination setting forth the Company's intention to consider
          terminating Executive's employment. Such Notice shall include a
          statement of the intended Date of Termination and a detailed
          description of the specific facts that the Company believes to
          constitute Cause.
               (2)  Any act or omission of Executive alleged to constitute Cause
          shall have occurred not more than 12 months before the earliest date
          on which any member of the Board who is not a party to the act or
          omission knew or in the reasonable exercise of his or her duties as a
          director should have know of such act or omission.
               (3)  Executive is offered an opportunity to respond to such
          Notice of Intent to Terminate by appearing in person, together with
          Executive's legal counsel, before the Board on a date specified in the
          Notice of Intent to Terminate, which date shall be at least 25 days
          after Executive's receipt of the Notice of Intent to Terminate and, in
          any event, at least five days prior to the Date of Termination
          proposed in such Notice.
               (4)  By a vote of the Board that includes the affirmative vote of
          at least 75% of the Non-Employee Directors, the Board determines that
          the actions of Executive specified in the Notice of Intent to
          Terminate constitute Cause and that Executive's employment should
          accordingly be terminated for Cause.
               (5)  The Company provides Executive with a copy of the Board's
          written determination pursuant to clause (4) setting forth in detail
          (a) the specific basis for such termination for Cause and (b) the Date
          of Termination (which date shall be not more than 15 days after the
          giving of such notice).
By determination of the Board, the Company may suspend Executive from
Executive's duties for a period of up to 30 days with full pay and benefits
thereunder during the period of time in which the Board is determining whether
to terminate Executive for Cause. Any purported termination for Cause by the
Company that does not satisfy each substantive and procedural requirement of
this Section 3(b) shall be treated for all purposes under this Agreement as a
termination by the Company without Cause.
                                       8
 
     (c)  Good Reason.  Executive may terminate Executive's employment at any
time during the Employment Period for Good Reason. "Good Reason" means any one
or more of the following:
          (i)    the assignment to Executive of any duties inconsistent in any
     respect with Executive's position (including status, offices and titles),
     authority, duties or responsibilities as contemplated by Section 2(a), or
     any other action by the Company which results in a diminution in such
     position, authority, duties or responsibilities, excluding an isolated,
     insubstantial and inadvertent action not taken in bad faith and which is
     remedied by the Company promptly after receipt of notice thereof given by
     Executive;
          (ii)   any failure by the Company to comply with any of the provisions
     of Section 2(b), other than an isolated, insubstantial and inadvertent
     failure not occurring in bad faith and which is remedied by the Company
     promptly after receipt of notice thereof given by Executive;
          (iii)  any requirement that Executive be based at any office or
     location other than the location specified in Section 2(a)(i)(B);
          (iv)   any purported termination by the Company of Executive's
     employment otherwise than as expressly permitted by this Agreement (it
     being understood that any such purported termination shall not be effective
     for any other purpose of this Agreement); or
          (v)    any failure by the Company to comply with Section 10(c).
          Any good faith determination of Good Reason made by Executive shall be
     conclusive.
     (d)  Notice of Termination.  Any termination of Executive's employment by
the Company or by Executive shall be communicated by Notice of Termination to
the other party hereto. "Notice of Termination" means a written notice which (i)
indicates the specific termination provision in this Agreement relied upon, (ii)
sets forth in reasonable detail the facts and circumstances claimed to provide a
basis for termination of Executive's employment under the provision so indicated
and (iii) specifies the Date of Termination (which date shall be not more than
15 days after the giving of such notice). The failure by Executive to set forth
in the Notice of Termination any fact or circumstance which contributes to a
showing of Good Reason shall not waive any right of Executive hereunder or
preclude Executive from asserting such fact or circumstance in enforcing
Executive's rights thereunder.
     4.   Obligations of the Company upon Termination.
     (a)  Good Reason; Other Than for Cause, Death or Disability.
          (i)    If, during the Employment Period, Executive's employment shall
     be terminated by the Company other than for Cause, or by reason of death or
     Disability, or by Executive for Good Reason, then the Company shall have
     all of the following obligations:
                                       9
 
               (A)  The Company shall pay to Executive the following amounts in
          a lump sum in cash within 10 days after the Date of Termination:
                    (1)  an amount equal to the sum of the Accrued Base Salary,
               the Accrued Annual Bonus, any compensation previously deferred by
               Executive under any non-qualified deferred compensation plan or
               arrangement (together with any accrued interest or earnings
               thereon) and accrued but unpaid vacation pay (collectively, the
               "Accrued Obligations"),
                    (2)  the Prorated Annual Bonus, and
                    (3)  the product of [two] [three] times the sum of (x) the
               Annual Base Salary and (y) the Annual Bonus.
               (B)  Any stock options or similar equity incentive rights
          previously granted to Executive that are not then fully vested and
          exercisable pursuant to their terms shall become fully vested and
          immediately exercisable on the Date of Termination and, together with
          any stock options or similar equity incentive rights that vested on
          the Effective Date (to the extent such options or rights have not
          expired pursuant to their terms and are unexercised), remain
          exercisable until the earlier of (x) expiration in accordance with
          their terms or (y) the first anniversary of the Date of Termination.
          As to any other types of equity-based incentive awards previously
          granted to Executive under any equity-based incentive compensation
          plan or arrangement of the Company, any restrictions on exercise,
          payment or transfer shall immediately lapse, and (unless waived or
          deferred by Executive) Executive shall be paid any cash or property
          underlying such award, within 10 days after the Date of Termination,
          in all respect as though any vesting requirements or any corporate or
          individual performance goals associated with such awards had been met
          as of the Date of Termination.
               (C)  (1)  During the period commencing on the Date of Termination
               and continuing thereafter for two years, or such longer period as
               provided in any plan or Policy in which Executive is a
               participant as of the Date of Termination (such eligibility to be
               determined based on the terms of such plan or Policy as in effect
               on the Effective Date or, if more favorable to Executive, the
               terms of such plan or Policy as in effect on the Date of
               Termination), the Company shall continue to provide, at no cost
               to Executive, medical, dental and similar health care benefits
               (or, if such benefits are not available, the after-tax economic
               value thereof determined pursuant to paragraph (3) of this
               Section 4(a)(i)(C)) to Executive and Executive's family.
                    (2)  The terms of such benefits shall be at least as
               favorable to Executive as the terms of the most favorable plans
               or Policies of the Company applicable to peer executives at
               Executive's Date of Termination, but in no event less favorable
               to Executive than the most favorable plans or Policies of the
               Company applicable to peer executives during the 90-day period
               immediately preceding the Effective Date.
                                       10
 
                    (3)  The after-tax economic value of any benefit to be
               provided pursuant to paragraph (i) above shall be deemed to be
               the present value of the premiums expected to be paid for all
               such benefits that are to be provided on an insured basis. The
               after-tax economic value of all other benefits shall be deemed to
               be the present value of the expected net cost to the Company of
               providing such benefits.
               (D)  The Company shall cause Executive to receive, at the
          Company's expense, standard outplacement services from a nationally-
          recognized firm selected by Executive; provided that the cost to the
          Company of such services shall not exceed 15% of the sum of (x) Annual
          Base Salary and (y) the Annual Bonus in effect on the Date of
          Termination.
          (ii)   If the present value as of the Effective Date, determined in
     accordance with Sections 280G(b)(2)(ii) and 280G(d)(4) of the Code (the
     "Present Value"), of the payments and distributions by the Company to or
     for the benefit of Executive (whether paid or payable or distributed or
     distributable pursuant to the terms of this Agreement or otherwise) in
     connection with, or arising out of, Executive's employment with the Company
     or a change in ownership or effective control of the Company or a
     substantial portion of its assets ("Payments") exceeds 110% of the greatest
     Present Value of Payments (the "Safe Harbor Cap") that could be paid to
     Executive such that the receipt thereof would not give rise to any excise
     tax, then at Executive's option the Company shall reduce the maximum
     amounts payable under this Agreement to the maximum amount that could be
     paid to Executive such that the Present Value of the Payments does not
     exceed the Safe Harbor Cap. The reduction of the amounts payable hereunder,
     if applicable, shall be made by reducing the payments as elected by
     Executive. For purposes of reducing the Payments to the Safe Harbor Cap,
     only amounts payable under this Agreement (and no other Payments) shall be
     reduced. If the reduction of the amounts payable hereunder would not result
     in a reduction of the Present Value of the Payments to the Safe Harbor Cap,
     no amounts payable under this Agreement shall be reduced pursuant to this
     paragraph.
          (iii)  All determinations required to be made under the first sentence
     of paragraph (ii) above shall be made by a nationally recognized certified
     public accounting firm (which shall not be the firm serving as accountant
     or auditor for the individual, entity or group effecting the Change in
     Control) designated by Executive, which shall provide detailed supporting
     calculations both to the Company and Executive within 15 business days
     after delivery by Executive to the Company of a written request for
     determination.  All fees and expenses of said accounting firm shall be
     borne solely by the Company.  Any determination by the accounting firm
     shall be binding upon the Company and Executive.
     (b)  Cause; Other than for Good Reason.  If, during the Employment Period,
Executive's employment is terminated (i) by the Company for Cause or (ii) by
Executive other than for Good Reason, the Company shall pay to Executive in a
lump sum in cash within 10 days after the Date of Termination any unpaid salary
earned, and any unpaid accrued vacation pay, as of the Date of Termination.
                                       11
 
     (c)  Death or Disability.  If, during the Employment Period, Executive's
employment is terminated by reason of Executive's death or Disability, the
Company shall pay an amount equal to all Accrued Obligations to Executive or
Executive's estate or beneficiary, as applicable, in cash a lump sum within 10
days after the Date of Termination.
     5.   Non-Exclusivity of Rights.  If Executive receives payments pursuant to
Section 4(a), Executive hereby waives the right to receive severance payments
under any other plan, policy or agreement of the Company. Except as provided in
the previous sentence, nothing in this Agreement shall prevent or limit
Executive's continuing or future participation in any benefit, bonus, incentive
or other plans or Policies provided by the Company or any of its Affiliated
Companies and for which Executive may qualify, nor shall anything herein limit
or otherwise affect such rights as Executive may have under any other agreements
with the Company or any of its Affiliated Companies.
     6.   Conflicts.  In the event of a conflict between the provisions of this
Agreement and the terms of any written agreement between the Company and
Executive evidencing any equity-based incentive awards with respect to a payment
or benefit to be made or provided to Executive this Agreement, whichever of the
provisions of this Agreement or such written agreement that are most favorable
to Executive will control.
     7.   Full Settlement.  The Company's obligation to make the payments
provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any circumstances, including set-off,
counterclaim, recoupment, defense or other claim, right or action that the
Company may have against Executive or others.
     8.   No Duty to Mitigate.  Executive shall not be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to Executive under any of the provisions of this Agreement, nor shall the amount
of any payment hereunder be reduced by any compensation earned by Executive as
result of employment by another employer or by any retirement benefits which may
be paid or payable to Executive; provided, however, that any continued welfare
benefits provided for pursuant to Section 4(a)(i)(C) shall not duplicate any
benefits that are provided to Executive and Executive's family by such other
employer and shall be second to any coverage provided by such other employer.
     9.   Enforcement.
     (a)  Reimbursement of Expenses.  If Executive incurs legal, accounting,
expert witness or other fees and expenses in an effort to establish entitlement
to compensation and benefits under this Agreement, the Company shall, regardless
of the outcome of such effort, pay or reimburse Executive for such fees and
expenses, together with an additional amount such that, after providing for the
Taxes payable by Executive in respect of such additional amount, there remains a
balance sufficient to pay the Taxes payable by Executive in respect of such
payment or reimbursement of fees and expenses by the Company. The Company shall
reimburse Executive for such fees and expenses on a monthly basis within 10 days
after its receipt of Executive's request for reimbursement accompanied by
reasonable evidence that the fees and expenses were incurred.
     (b)  Refund.  If Executive does not prevail (after exhaustion of all
available judicial remedies), and the Company establishes before a court of
competent jurisdiction that Executive
                                       12
 
had no reasonable basis for bringing an action hereunder and acted in bad faith
in doing so, no further reimbursement for legal fees and expenses shall be due
to Executive and Executive shall refund any amounts previously reimbursed
hereunder with respect to such action.
     (c)  Interest.  If the Company fails to pay any amount provided under this
Agreement when due, the Company shall pay interest on such amount at a rate
equal to 200 basis points over the prime commercial lending rate published from
time to time in The Wall Street Journal (Midwest Edition); provided, however,
that the interest rate determined in accordance with this Section shall in no
event exceed the highest legally-permissible interest rate.
     10.  Successors.
     (a)  Successors to Executive.  This Agreement is personal to Executive and
without the prior written consent of the Company shall not be assignable by
Executive otherwise than by will or the laws of descent and distribution. This
Agreement shall inure to the benefit of and be enforceable by Executive's legal
representatives.
     (b)  Successors to Company.  The Company may not assign its rights and
obligations under this Agreement without the prior written consent of Executive
except to a successor which has satisfied the provisions of Section 10(c).  This
Agreement shall inure to the benefit of the Company and such permitted assigns.
     (c)  Obligations of Company's Successors.  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 assume expressly and agree to perform this 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.  All references to the Company shall also
refer to any such successor, and the Company and such successor shall be jointly
and severally liable for all obligations of the Company under this Agreement.
     11.  Miscellaneous.
     (a)  Applicable Law.  This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, without reference to such
State's principles of conflict of laws.

     (c)  Severability.  If any part of this Agreement is declared by any court
or governmental authority to be unlawful or invalid, such unlawfulness or
invalidity shall not serve to invalidate any part of this Agreement not declared
to be unlawful or invalid. Any paragraph or part of a paragraph so declared to
be unlawful or invalid shall, if possible, be construed in a manner which will
give effect to the terms of such paragraph or part of a paragraph to the fullest
extent possible while remaining lawful and valid.

any default shall not result in a waiver of any later default.

the Company and Executive with respect to the subject matter hereof, and shall
supersede all prior agreements, promises and representations of the parties
regarding employment or severance, whether in writing or otherwise.

together will constitute one and the same instrument.
