3.    Compensation and Benefits

      3.1   Compensation.

            (a)   Base Salary. The Company shall pay Executive an annual salary
                  of $180,000.00, payable in bi-weekly installments, in arrears
                  (the "Base Salary"). The Base Salary shall be reviewed
                  annually by the Company's President (or, if Executive is in
                  the future designated as an executive officer of Curative
                  Health Services, Inc., then by its Board of Directors) and may
                  be increased, but not decreased (unless mutually agreed upon
                  by Executive and the Company).

            (b)   Bonus Plan. Executive shall be entitled to participate in the
                  Company's Annual Corporate Bonus Plan, in accordance with and
                  subject to the terms and provisions thereof.

            (c)   Stock Option Grant. On the Effective Date, Curative shall
                  issue and Executive shall receive a non-qualified stock option
                  to purchase 50,000 shares of Curative's Common Stock, pursuant
                  to Curative's 2001 Broad-Based Stock Incentive Plan, as
                  amended (the "Plan"). The terms and conditions of said stock
                  option shall be set forth in and governed entirely by
                  Curative's standard stock option agreement, which Executive
                  shall sign as a condition of receiving said stock option, and
                  nothing contained in this Agreement is intended to alter the
                  provisions of such stock option agreement or the Plan. The
                  exercise price of the Common Stock underlying this stock
                  option shall equal the closing sales price of Curative's
                  Common Stock as quoted on the NASDAQ National Market System on
                  the Effective Date.

      3.2 Participation in Benefit Plans. Executive shall be entitled to
participate in all employee benefit plans or programs of the Company to the
extent that his position, title, tenure (treating Executive's prior service for
Critical Care Services, Inc. as if it were service for the Company), salary,
active employment status and other qualifications make him eligible to
participate. The Company does not guarantee the continuance of any particular
employee benefit plan or program during the Term, and Executive's participation
in any such plan or program shall be subject to all terms, provisions, rules and
regulations applicable thereto. Executive will be entitled to twenty (20) days
of vacation per year, to be used in accordance with the Company's vacation
policy for senior executives as it may change from time to time. For the Benefit
Period, if any, (as hereinafter defined), the Company will arrange to provide
Executive with welfare benefits (including life and health insurance benefits)
of substantially similar design and cost to Executive as the welfare benefits
and other employee benefits available to Executive prior to Executive's or the
Company's, as the case may be, receipt of a Notice of Termination (as
hereinafter defined). In the event that Executive shall obtain full-time
employment providing welfare benefits during the Benefit Period, such benefits
as otherwise receivable hereunder by Executive shall be discontinued.

reasonable and necessary out-of-pocket expenses incurred by him in the
performance of his duties under this Agreement. Executive shall keep detailed

his duties hereunder and reimbursement therefore shall be in accordance with
policies and procedures to be established from time to time by the Board.

Company's automobile policy, Executive shall be reimbursed by the Company for
the monthly lease expense for an automobile leased in the name of the Executive,

notice to the Company. Executive's right to terminate his employment pursuant to
this Section 4.4 shall not be affected by incapacity due to physical or mental
illness. Executive's continued employment following a Change of Control shall
not constitute consent to, or a waiver of rights with respect to, any
circumstance constituting Good Reason hereunder.

      4.5 Compensation Upon Termination.

            (a) Termination Prior to Change of Control. In the event the Company
terminates (or elects not to renew) this Agreement without Cause, and such
termination (or nonrenewal) without Cause occurs prior to any Change of Control,
or in the event Executive terminates (or elects not to renew) this Agreement for
Good Reason described in Section 4.1 (d)(i) or (iii) (even though such reason
occurs prior to a Change of Control), Executive shall be entitled to receive his
Base Salary through the Date of Termination, the welfare benefits described in
Section 3.2 for the Benefit Period, and not later than thirty (30) days after
the Date of Termination, a lump sum severance payment equal to the sum of six
(6) months of Executive's then current Base Salary plus a pro-rated bonus based
on Executive's performance in the fiscal year in which the Date of Termination
occurs. In addition, to the extent not otherwise required under the Company's
Stock Option Plan or any award agreement with Executive, any unvested stock
option awards theretofore awarded to Executive which would otherwise vest and
become exercisable during the twelve (12) month period commencing on the Date of
Termination shall vest and become exercisable beginning on the Date of
Termination in accordance with the applicable option agreement. In the event
this Agreement is terminated (or not renewed) for any reason other than by the
Company without Cause or by Executive for Good Reason described in Section 4.1
(d)(i) or (iii), and such termination (or nonrenewal) occurs prior to a Change
of Control, Executive shall not be entitled to the continuation of any
compensation, bonuses or benefits provided hereunder, or any other payments
following the Date of Termination, other than Base Salary earned through such
Date of Termination.

            (b) Termination Following Change of Control. If this Agreement is
terminated (or not renewed) (i) by the Company without Cause, or (ii) by
Executive for Good Reason during the twelve (12) month period immediately
following a Change of Control, and such termination (or nonrenewal) occurs
following a Change of Control, Executive shall be entitled to receive his full
Base Salary through the Date of Termination, the welfare benefits described in
Section 3.2 for the Benefit Period and, not later than thirty (30) days after
the Date of Termination, a lump sum severance payment equal to the sum of
Executive's then current Base Salary plus a pro-rated bonus based on Executive's
performance in the fiscal year in which the Date of Termination occurs. In
addition, to the extent not otherwise required under the Company's Stock Option
Plan or any award agreement with Executive, any unvested stock option awards
theretofore awarded to Executive shall vest and become immediately exercisable
in full. In the event this Agreement is terminated (or not renewed) for any
reason other than (i) by the Company without Cause, or (ii) by Executive for
Good Reason, and such termination (or nonrenewal) occurs following a Change of
Control, Executive shall not be entitled to the continuation of any
compensation, bonuses or benefits provided hereunder, or any other payments
following the Date of Termination, other than Base Salary earned through the
Date of Termination.

            (c) At Executive's option to be exercised by written notice to the
Company, the severance benefits payable under this Section 4.5 shall be paid in
accordance with the Company's normal payroll procedures over the six (6) or
twelve (12) month period, as the case may be, corresponding to the amount of the
payments instead of in a lump sum.

            (d) Anything to the contrary contained herein notwithstanding, as a
condition to Executive receiving severance benefits to be paid pursuant to this
Section 4.5, Executive shall execute and deliver to the Company a general
release in form and substance reasonably satisfactory to the Company releasing
the Company, its subsidiaries, affiliates and their respective officers,
directors, employees and agents from all liabilities, claims and obligations of
any nature whatsoever, excepting only the Company's obligations under this
Agreement, under any Stock Option Agreements, and under any other employee
benefit plans or programs in which Executive participates under Section 3.2
hereof, subject to all terms and conditions of such plans or programs and this
Agreement.

            (e) Anything to the contrary contained herein notwithstanding, in
the event that any payment or benefit received or to be received by Executive in
connection with a Change in Control of the Company or termination of Executive's
employment (whether payable pursuant to the terms of this Agreement or any other
plan, contract, agreement or arrangement with the Company, with any person whose
actions result in a Change in Control of the Company or with any person
constituting a member of an "affiliated group" as defined in Section 280G(d)(5)
of the Internal Revenue Code of 1986, as amended (the "Code"), with the Company
or with any person whose actions result in a Change in Control of the Company
(collectively, the "Total Payments") would not be deductible (in whole or in
part) by the Company or such other person making such payment or providing such
benefit solely as a result of Section 280G of the Code, the amount payable to
Executive pursuant to this Section 4.5 shall be reduced until no portion of the
Total Payments is not deductible solely as a result of Section 280G of the Code
or such amount payable to Executive pursuant to Section 4.5 is reduced to zero.
For purposes of this limitation, (a) no portion of the Total Payments the
receipt or enjoyment of which Executive shall have effectively waived in writing
prior to the date of payment of the amount pursuant to Section 4.5 shall be
taken into account; (b) no portion of the Total Payments shall be taken into
account which in the opinion of tax counsel selected by the Company and
reasonably acceptable to Executive does not constitute a "parachute payment"
within the meaning of Section 280G(b)(2) of the Code; (c) the payment pursuant
to Section 4.5 shall be reduced only to the extent necessary so that the Total
Payments (other than those referred to in the immediately preceding clause (b))
in their entirety constitute reasonable compensation within the meaning of
Section 280G(b)(4)(B) of the Code, in the opinion of the tax counsel referred to
in the immediately preceding clause (b); and (d) the value of any other non-cash
benefit or of any deferred cash payment included in the Total Payments shall be
determined by the Company's independent auditors in accordance with the
principles of Sections 280G(d)(3) and (4) of the Code.

of the new employer or affiliation. Without limiting the foregoing, Executive's
obligation to give notice under this Section 5.4 shall apply to any business
ventures in which Executive proposes to engage, even if not with a third-party
employer (such as, without limitation, a joint venture, partnership or sole
proprietorship). Executive hereby consents to the Company notifying any such new
employer or business venture of the terms of the covenants in this Section 5.4.

      5.5 Restricted Period. As used in this Section 5, "Restricted Period"
shall mean the period between the Effective Date and 12 months after the
termination of Executive's employment with the Company for any reason (whether
such termination is occasioned by Executive or the Company). If Executive
violates this Agreement, then the duration of the restrictions contained in
paragraph 5 shall be extended for an amount of time equal to the period of time
during which Employee was in violation of the Agreement.

      5.6 Judicial Action. Executive and the Company agree that, if the period
of time or the scope of the restrictive covenant not to compete contained in
this Section 5 shall be adjudged unreasonable in any court proceeding, then the
period of time and/or scope shall be reduced accordingly, so that this covenant
may be enforced in such scope and during such period of time as is judged by the
court to be reasonable. In the event of a breach or violation of this Section 5
by Executive, the parties agree than in addition to all other remedies, the
Company shall be entitled to equitable relief for specific performance, and
Executive hereby agrees and acknowledges that the Company has no adequate remedy
at law for the breach of the covenants contained herein.

      5.7 Exclusivity of Employment. During the Term, Executive shall not
directly or indirectly engage in any activity competitive with or adverse to the
Company's business or welfare or render a material level of services of a
business, professional or commercial nature to any other person or firm, whether
for compensation or otherwise.

6.    Confidential Information

      In consideration for the Company's promises under this Agreement and
because Executive's duties as an employee will necessitate having access to and
being entrusted with confidential and proprietary information relating to the
Company's business and customers, Executive agrees that during employment with
Executive and thereafter, Executive shall not disclose to a third party or use
for Executive's personal benefit Confidential Information of the Company.
"Confidential Information" means


                                       9
<PAGE>

all information written (or generated/stored on magnetic, digital, photographic
or other media) or oral, relating to any aspect of the Company's existing
business or future strategic or business plans which is disclosed to Executive
or conceived, discovered or developed by Executive, and which is not generally
known by or available through legal means to the public or proprietary to the
Company, including any such information relating to any subsidiary or affiliate
of the Company. Confidential Information includes, without limitation, the
Company's strategic and other business plans, designs, customers, suppliers,
manufacturers, distributors and the Company's marketing, accounting,
merchandising, and information-gathering techniques and methods, and all
accumulated data, listings, or similar recorded matter used or useful in the
Company's business, including but not limited to technical or non-technical
data, formulas, patterns, compilations, programs, devices, methods, business
forms, techniques, drawings, processes, pricing information, financial data,
financial plans, products plans, or lists of actual or potential customers,
clients, distributees or licensees, referral sources, information concerning the
Company's finances, services, staff, contemplated acquisitions, marketing
investigations and surveys. All information disclosed to Executive or to which
Executive has access during the period of this employment, for which there is
any reasonable basis to believe is, or which appears to be treated by Executive
as Confidential Information, shall be presumed to be Confidential Information
under this Agreement. In addition, Executive shall comply with the terms of any
Confidentiality Agreement by which Executive is bound to a third party. For
purposes of this Section 6, the Company shall include any parents, subsidiaries
and affiliates of the Company.

7.    Inventions

      7.1 Invention Defined. As used in this Section, the term "Invention" means
all inventions, discoveries, improvements, processes, developments, designs,
know-how, data, computer programs and formulae, designed or conceived by
Executive during the Term of this Agreement which reasonably relate to the
Company's business or result from duties Executive performs for Company, or
result from use of any premises or property owned, leased, licensed or
contracted for by Company, whether patentable or unpatentable or protectable by
copyright or other intellectual property law.

      7.2 Disclosure and Assignment of Inventions. Executive agrees that
Executive's services on behalf of the Company are works made for hire and
Executive shall communicate to the Company as promptly and fully as practicable
all Inventions made, conceived, reduced to practice or originated by Executive,
either solely or jointly with others, during the Term of Executive's employment
with the Company and to assign, transfer, and convey to Executive or its
authorized representatives, both during or subsequent to the Term of Executive's
employment with the Company, upon request all right, title, and interest in and
to all such Inventions. In addition, Executive shall communicate to the Company
as promptly and fully as practicable all Inventions which are (or were)
conceived or reduced to practice by Executive (alone or jointly with others)
within one (1) year following the termination of Executive's employment with the
Company for any reason, and whether occasioned by Executive or the Company.

      7.3 Participation in Protecting Inventions. Executive shall furnish to the
Company, upon its request and at its expense, all written assignments,
transfers, affidavits, certifications and other documents the Company may
request in order to confirm the fact of the Company's


                                       10
<PAGE>

ownership of any of its property. Upon reasonable request, Executive shall
assist the Company and/or its nominees (without charge but at no expense to
Executive) at any time and in every proper way to obtain for its and/or their
own benefits, patents and copyrights for all such Inventions anywhere in the
world and to enforce its and/or their rights in any Invention in legal
proceedings. In the event the Company is unable to secure Executive's assistance
after the Company's reasonable request with regard to executing or filing any
document needed to apply for or prosecute any patent, copyright, trademark,
trade secret or other right or protection relating to an Invention, Executive
hereby irrevocably designates and appoints the Company and each of its duly
authorized officers and agents as Executive's agent and attorney-in-fact to act
for and in Executive's behalf and stead to execute and file any document and to
do all other lawfully permitted acts to further the prosecution, issuance, and
enforcement of patents, copyrights and other proprietary rights in any way
relating to an Invention with the same force and effect as if executed and
delivered by Executive.

      7.4 Disclosure of Existing Inventions. Executive agrees to provide, in
conjunction with this Agreement, a complete list and brief description of all
Inventions made, conceived, and reduced to practice by Executive prior to
commencing employment with the Company and which Executive does not intend to
include in the assignment provision set forth in Section 7.2. Except as so
listed, Executive agrees not to assert any rights under any Inventions made or
acquired by Executive prior to commencing employment with the Company. The
Company further agrees to provide a detailed description and/or working model of
any Invention so listed, at the request of the Company.

      7.5 Inventions Excluded. Any provision in this Section requiring Executive
to assign Executive's rights in any Invention does not apply to an Invention
which qualifies for exclusion under state law, which, if applicable, provides
that that the requirement to assign shall not apply to an Invention that
Executive developed entirely on Executive's own time without using the Company's
equipment, supplies, facilities or trade secret information except for those
Inventions that either: (1) relate at the time of conception or reduction to
practice to the Company's business, or actual or demonstrably anticipated
research or development of the Company; or (2) result from any work performed by
Executive for the Company. Executive further understands that Executive bears
the burden of proving that an Invention qualifies for exclusion under these
provisions.
