statement by the Company to shareholders requesting an affirmative vote

that 40 percent or more of its outstanding common stock has been acquired by any
person (as defined under the 1934 Act), the Company shall contribute to an
irrevocable grantor trust (a "Rabbi Trust") an amount sufficient to enable all
potential amounts due to Employee under this Section to be paid. The Company
shall provide Employee with a certification of the payment to such trust of all
such amounts. All such amounts which are due to Employee shall be paid using the
assets of said trust except to the extent its terms preclude such payment, in
which event payment shall be made by the Company from its own funds, or unless
the Company elects to pay any or all such amounts from its own funds.

     10. PARACHUTES.

     (a) APPLICATION. If all, or any portion, of the payments provided under
this Agreement, and/or any other payments and benefits that Employee receives or
is entitled to receive from Sabratek, including, but not limited to, amounts
generated from the exercise and sale of options granted to Employee, constitutes
an excess "parachute payment" within the meaning of Section 280G(b) of the Code,
whether or not under an existing plan, arrangement or other agreement (each such
parachute payment, a "Parachute Payment") and will result in the imposition on
Employee of an excise tax under Section 4999 of the Code, then, in addition to
any other benefits to which



                                       12


<PAGE>   13



Employee is entitled under this Agreement, Sabratek shall pay him an amount in
cash equal to the sum of the excise taxes payable by him by reason of receiving
such Parachute Payments, plus the amount necessary to put him in the same
after-tax position (taking into account any and all applicable federal, state
and local excise, income or other taxes at the highest possible applicable rates
on such Parachute Payments (including without limitation any payments under this
Section 10) as if no excise taxes had been imposed with respect to Parachute
Payments (the "Parachute Gross-up").

     (b) COMPUTATION. The amount of any payment under this Section 10 shall be
computed by Sabratek's certified public accounting firm in consultation with
legal counsel acceptable to Employee. Employee and Sabratek shall provide the
accounting firm with all information that it reasonably deems necessary in order
to compute the Parachute Gross-up. The cost and expenses of the accounting firm
retained to perform the computations shall be borne by Sabratek.

     (c) PAYMENT. In any event, Sabratek shall pay to Employee, or pay on his
behalf, the Parachute Gross-up as computed by the accounting firm by the time
any taxes payable by him as a result of the Parachute Payments become due.

     In the event that the Internal Revenue Service ("IRS") determines that the
amount of excise taxes thereon initially paid was insufficient to discharge
Employee's excise tax liability, Sabratek shall make additional payments to him
as may be necessary to reimburse him for discharging the full liability.

<PAGE>   14


     11. CONFIDENTIALITY AND LOYALTY.

     (a) GENERAL.

          (i)   Employee hereby acknowledges that as a result of his employment
with Sabratek he has produced and had access to, and may hereafter produce and
have access to, material, records, data, trade secrets, inventions and
information not generally available to the public (collectively, "Confidential
Information") regarding Sabratek and that any such Confidential Information is
the exclusive property of Sabratek.

          (ii)  Accordingly, Employee hereby agrees that, during and subsequent
to the Term, he shall hold in confidence and not directly or indirectly
disclose, use, copy or make lists of any such Confidential Information, except
to the extent that such information is or thereafter becomes lawfully available
from public sources, or such disclosure is authorized in writing by Sabratek,
required by a law or any competent administrative agency or judicial authority,
or otherwise as reasonably necessary or appropriate in connection with
performance by Employee of his duties hereunder.

     (b) RETURN OF DOCUMENTS. All records, files, documents and other materials
or copies thereof relating to Sabratek's business that Employee prepares or uses
shall be and remain the sole property of Sabratek and shall not be removed from
Sabratek's premises without its written consent. Upon termination of Employee's
employment with Sabratek for any reason, he shall promptly deliver to Sabratek
all such items that are then in his possession or control.

     (c) DUTY OF LOYALTY. Employee hereby agrees to abide by Sabratek's
reasonable policies, as in effect from time to time, respecting avoidance of
interests conflicting with those of Sabratek.




                                       14


<PAGE>   15


     (d) REMEDIES AND SANCTIONS. In the event that Employee is found to be in
violation of Section 11(a), (b) or (c), Sabratek shall be entitled to relief as
provided in Section 13 below.

     12. NONCOMPETITION/NONSOLICITATION.

     (a) RESTRICTIVE COVENANT. Employee hereby agrees that, except with the
express prior written consent of Sabratek, for a period of one year after
termination of his employment with Sabratek for any reason (the "Restrictive
Period"), he will not directly or indirectly compete with the business of
Sabratek as conducted on the date of such termination, including, but not by way
of limitation, by (i) directly or indirectly owning, managing, operating,
controlling, financing, (ii) directly or indirectly serving as an employee,
officer or director of or consultant to, or (iii) soliciting or inducing, or
attempting to solicit or induce, any employee or agent of Sabratek to terminate
employment with Sabratek and become employed by, any person, firm, partnership,
corporation, trust or other entity that owns or operates an entity that is
engaged in the same or similar business as Sabratek as conducted on the date of
such termination (the "Restrictive Covenant").

     If Employee violates the Restrictive Covenant and Sabratek brings legal
action for injunctive or other relief, Sabratek shall not, as a result of the
time involved in obtaining such relief, be deprived of the benefit of the full
period of the Restrictive Covenant. Accordingly, the Restrictive Covenant shall
be deemed to endure for the period specified in this Section 12(a), computed
from the date the relief is granted but reduced by the time between the period
when the Restrictive Period began to run and the date of the first violation of
the Restrictive Covenant by Employee.

     (b) EXCEPTIONS. Notwithstanding anything to the contrary in Section 12(a),
the Restrictive Covenant shall not:




                                       15

<PAGE>   16


         (i)  apply if Sabratek terminates Employee's employment without Cause,
as provided in Section 9(f) above; or

         (ii) prohibit Employee from owning directly or indirectly capital stock
or similar securities which do not represent more than five percent of the
outstanding capital stock of any business similar to that of Sabratek as
conducted on the date of such termination.

     (c) REMEDIES AND SANCTIONS. In the event that Employee is found to be in
violation of Section 12(a) above, Sabratek shall be entitled to relief as
provided in Section 13 below.

     13. REMEDIES/SANCTIONS.

     Employee hereby acknowledges that the restrictions contained in Sections 11
(a), (b) and (c) and 12(a) above are reasonable and necessary for the protection
of the legitimate business interests of Sabratek, for which monetary damages
alone may not provide an adequate remedy, that any violation of these
restrictions would cause substantial injury to Sabratek and such interests, that
Sabratek would not have entered into this Agreement without receiving the
additional consideration offered by Employee in binding himself to these
restrictions and that such restrictions were a material inducement to Sabratek
to enter into this Agreement.

     In the event of any violation or threatened violation of these
restrictions, Sabratek (a) shall be relieved of any further obligations under
the Agreement, (b) shall be entitled to monetary damages resulting from such
violation, and (c) in addition to and not in limitation of, any other rights,
remedies or damages available to Sabratek under this Agreement or otherwise at
law or in equity, shall be entitled to preliminary and permanent injunctive

     14. BENEFICIARIES/REFERENCES.

     Employee shall be entitled to select (and change, to the extent permitted
under any applicable law) a Beneficiary or Beneficiaries to receive any
compensation or benefit payable under this Agreement following his death by
giving Sabratek written notice thereof. In the event of Employee's death, or of
a judicial determination of his incompetence, reference in this Agreement to
Employee shall be deemed to refer, as appropriate, to his Beneficiary, estate or
other legal representative.

     15. WITHHOLDING TAXES.

     All payments to Employee or his Beneficiary under this Agreement shall be
subject to withholding on account of federal, state and local taxes as required
by law.

     16. INDEMNIFICATION AND LIABILITY INSURANCE.

     Nothing herein is intended to limit Sabratek's indemnification of Employee,
and Sabratek shall indemnify him to the fullest extent permitted by applicable
law consistent with Sabratek's Certificate of Incorporation and By-Laws as in
effect at the beginning of the Term, with respect to any action or failure to
act on his part while he is an officer, director or employee of Sabratek.
Sabratek shall cause Employee to be covered at all times by directors' and
officers' liability insurance on terms no less favorable than the directors' and
officers' liability insurance maintained by Sabratek in effect on the date
hereof in terms of coverage and amounts. Sabratek shall continue to indemnify
Employee as provided above and maintain such liability insurance coverage for
him after the Term for any claims that may be made against him with respect to
his service as a director or officer of Sabratek.

     17. EFFECT OF AGREEMENT ON OTHER BENEFITS.

     The existence of this Agreement shall not prohibit or restrict Employee's
entitlement to participate fully in compensation, employee benefit and other
plans of Sabratek in which senior executives are eligible to participate.

     18. ASSIGNABILITY; BINDING NATURE.

     This Agreement shall be binding upon and inure to the benefit of the
Parties and their respective successors, heirs (in the case of Employee) and
assigns. No rights or obligations of Sabratek under this Agreement may be
assigned or transferred by Sabratek except pursuant to (a) a merger or
consolidation or (b) sale or liquidation of all or substantially all of the
assets of Sabratek, provided that the surviving entity or assignee or transferee
is the successor to all or substantially all of the assets of Sabratek and, in
the case of a sale or other transfer of assets or a merger in which Sabratek is
not the surviving entity, such surviving entity or assignee or transferee agrees
in writing to assume the liabilities, obligations and duties of Sabratek under
this Agreement. Notwithstanding such assignment, Sabratek shall remain liable
and responsible for fulfillment of the terms and conditions of this Agreement;
and provided further, that in no event shall such assignment of this Agreement
adversely affect Employee's right upon a Change in Control, as provided in
Section 9(i) above. No rights or obligations of Employee under this Agreement
may be assigned or transferred by him.

     19. REPRESENTATIONS.

     The Parties respectively represent and warrant that each is fully
authorized and empowered to enter into this Agreement and that the performance
of its or his obligations, as the case may be, under this Agreement will not
violate any agreement between such Party and any other person, firm



                                       18

or organization. Sabratek represents and warrants that this Agreement has been
duly authorized by all necessary corporate action and is valid, binding and
enforceable in accordance with its terms.

     20. ENTIRE AGREEMENT.

     Except to the extent otherwise provided herein, this Agreement contains the
entire understanding and agreement between the Parties concerning the subject
matter hereof and supersedes any prior agreements, whether written or oral,
between the Parties concerning the subject matter hereof, provided that the
execution of this Agreement shall not adversely affect (i) any award previously
made to Employee under any compensation plan maintained by Sabratek, or (ii) any
statements regarding the vesting of options or other benefits in such prior
agreements. Payments and benefits provided under this Agreement are in lieu of
any payments or other benefits under any severance program or policy of Sabratek
to which Employee would otherwise be entitled.

     21. AMENDMENT OR WAIVER.

     No provision in this Agreement may be amended unless such amendment is
agreed to in writing and signed by both Employee and an authorized officer of
Sabratek. No waiver by either Party of any breach by the other Party of any
condition or provision contained in this Agreement to be performed by such other
Party shall be deemed a waiver of a similar or dissimilar condition or provision
at the same or any prior or subsequent time. Any waiver must be in writing and
signed by the Party to be charged with the waiver. No delay by either Party in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof.

     22. SEVERABILITY.

     In the event that any provision or portion of this Agreement shall be
determined to be invalid or unenforceable for any reason, in whole or in part,
the remaining provisions of this Agreement



                                       19

<PAGE>   20



shall be unaffected thereby and shall remain in full force and effect to the
fullest extent permitted by law.

     23. SURVIVAL.

     The respective rights and obligations of the Parties under this Agreement
shall survive any termination of Employee's employment with Sabratek.

     24. GOVERNING LAW/JURISDICTION.

     This Agreement shall be governed by and construed and interpreted in
accordance with the laws of Illinois, without reference to principles of
conflict of laws.

     25. ARBITRATION.

     Any dispute or controversy other than a dispute or controversy arising
under Sections 11 or 12 hereof (actions regarding which may be brought in any
court (i) having situs within Cook County, Illinois and (ii) having jurisdiction
over the dispute or controversy) arising under or in connection with this
Agreement shall be settled exclusively by arbitration, conducted before a panel
of three arbitrators sitting in a location selected by Employee within thirty
(30) miles from the main office of Sabratek, in accordance with the rules of the
American Arbitration Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction; provided, however, that the
Executive shall be entitled to seek specific performance of his right to be paid
through the date of termination during the pendency of any dispute or
controversy arising under or in connection with this Agreement.

     26. LEGAL FEES.

     All reasonable expenses and legal fees paid or incurred by Employee
pursuant to any bona fide dispute or question of interpretation relating to this
Agreement, including all such expenses and

<PAGE>   21



fees, if any, incurred in contesting any termination of this Agreement by
Sabratek or in seeking to obtain or enforce any right or benefit provided by
this Agreement, shall be paid or reimbursed by Sabratek, provided, however, that
if this Agreement is terminated for Cause or if this Agreement is terminated
voluntarily by Employee other than due to a breach of this Agreement by
Sabratek, Sabratek shall be obligated to pay any of Employee's expenses and
legal fees arising therefrom only if Employee is successful on the merits
pursuant to a legal judgment, arbitration or settlement.
