         Summary of Other Terms: This Option is defined in the Stock Option

to this Option Certificate (the "Certificate") as Annex I. This Certificate
summarizes certain of the provisions of the Option Agreement for your
information, but is not complete. Your rights are governed by the Option

review the full Option Agreement prior to signing this Certificate or exercising
the Option.

         Among the terms of the Option Agreement are the following:

your death. See Paragraph 7.

certificate to you for the Shares you have purchased. You are under no
obligation to exercise the Option. See Paragraph 4.

         Anti-dilution Provisions: The Option contains provisions which adjust
your Option to reflect stock splits, stock dividends, mergers and other major
corporate reorganizations which would change the nature of the Shares underlying
your Option. See Paragraph 9.

         Agreement:  By signing this Certificate, you will be agreeing to all of
the terms of the Option Agreement, including those not summarized in this
Certificate.

         Withholding:  The Company may require you to make any arrangements

         WHEREAS, Optionee is a consultant to the Company;

         WHEREAS, the execution of a nonqualified stock option agreement in the
form hereof has been duly authorized by a resolution of the Board of Directors
(the "Administrator") of the Company (the date of such authorization, the "Date
of Grant") and incorporated herein by reference; and

         WHEREAS, the option granted hereunder is intended as a nonqualified
stock option and shall not be treated as an "incentive stock option" ("Incentive
Stock Option") within the meaning of that term under Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code").

         NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements herein contained, the parties hereto hereby agree as follows:

         1.   Definitions. Capitalized terms used and not defined herein shall
              -----------
have the meanings given to them in the Company's 1996 Consultants Warrant Stock
Plan (the "Plan"). For the purposes of this Agreement, the following additional
terms have the following meanings:

              (a)      "Cause" means:

                   (i)     the failure or refusal by Optionee to perform his or
         her duties to the Company, a Parent or Subsidiary; or

                   (ii)    Optionee's willful disobedience of any orders or
         directives of the Board or any officers thereof acting under the
         authority thereof or Optionee's deliberate interference with the
         compliance by employees of, or other consultants to, the Company, a
         Parent or Subsidiary with any such orders or directives; or

                   (iii)   the failure or refusal of Optionee to abide by or
         comply with the written policies, standard procedures or regulations of
         the Company, a Parent or Subsidiary; or

                   (iv)    any willful or continued act or course of conduct by
         Optionee that the Administrator in good faith determines might
         reasonably be expected to have a material detrimental effect on the
         Company, a Parent or Subsidiary or the business, operations, affairs or
         financial position thereof; or

                                      I-2
<PAGE>

                    (v)       the committing by the Optionee of any fraud,
         theft, embezzlement or other dishonest act against the Company, a
         Parent or Subsidiary; or

                    (vi)      the determination by the Administrator, in good
         faith and in the exercise of reasonable discretion, that Optionee is
         not competent to perform his or her duties as a consultant.

               (b)       "Change in Control" means the occurrence of any of the
following events:

                    (i)       The execution by the Company of an agreement for
         the merger, consolidation or reorganization into or with another
         corporation or other legal person; provided, however, that no such
         merger, consolidation or reorganization shall constitute a Change in
         Control if as a result of such merger, consolidation or reorganization
         not less than a majority of the combined voting power of the then-
         outstanding securities of such corporation or person immediately after
         such transaction are held in the aggregate by the holders of securities
         of the Company entitled to vote generally in the election of Directors
         ("Voting Stock") immediately prior to such transaction;

                    (ii)      The execution by the Company of an agreement for
         the sale or other transfer of all or substantially all of its assets to
         another corporation or other legal person; provided, however, that no
         such sale or other transfer shall constitute a Change in Control if as
         a result of such sale or transfer not less than a majority of the
         combined voting power of the then-outstanding securities of such
         corporation or person immediately after such sale or transfer is held
         in the aggregate by the holders of Voting Stock immediately prior to
         such sale or transfer.

                    (iii)     There is a report filed on Schedule 13D or
         Schedule 14D-1 (or any successor schedule, form or report), each as
         promulgated pursuant to the Exchange Act, disclosing or the Company is
         otherwise notified that any person (as the term "person" is used in
         Section 13(d)(3) or Section 14(d)(2) of the Exchange Act) has or
         intends to become the beneficial owner (as the term "beneficial owner"
         is defined under Rule 13d-3 or any successor rule or regulation
         promulgated under the Exchange Act) of securities representing 20% or
         more of the combined voting power of the then-outstanding Voting Stock,
         including, without limitation, pursuant to a tender offer or exchange
         offer; provided, however, that the following acquisitions shall not
         constitute a Change in Control: (A) any acquisition directly from the
         Company that is approved by the Incumbent Board (as defined below), (B)
         any acquisition by the Company or (C) any acquisition by any employee
         benefit plan (or related trust) sponsored or maintained by the Company
         or any Subsidiary;

                    (iv)      If, during any period of two consecutive years,
         individuals who at the beginning of any such period constitute the
         Directors of the Company (the "Incumbent Board") cease for any reason
         to constitute at least a majority thereof; provided, however, that for
         purposes of this subsection (iv) each Director who is first elected, or
         first nominated for election by the Company's stockholders, by a vote
         of at least two-thirds of the Directors of the Company (or a committee
         thereof) then still in office who were Directors of the Company at the
         beginning of any such period shall be deemed to have been a Director of
         the Company at the beginning of such period; or

                                      I-3
<PAGE>

                    (v)    except pursuant to a transaction described in the
         proviso to subsection (i) of this Section 1(b), the Company adopts a
         plan for the liquidation or dissolution of the Company.

         2.    Option. Pursuant to the Plan, the Company hereby grants to
               ------
Optionee an option (the "Option") to purchase that number of shares (the "Option
Shares") of the Company's Stock (the "Common Shares"), set forth in the
Certificate at the price per share set forth in the Certificate (the "Exercise
Price"), and agrees to cause certificates for any Common Shares purchased
hereunder to be delivered to Optionee upon payment in full of the Exercise
Price, subject to the applicable terms and conditions of the Plan and the terms
and conditions hereinafter set forth.

         3.    Vesting of Option Shares.
               ------------------------

               (a)  Unless and until terminated as hereinafter provided, the
Option shall become exercisable (in whole or in part) upon and after the dates
set forth in the Certificate under the caption "Exercise Schedule." To the
extent that the Option shall have so become exercisable, it may be exercised in
whole or in part from time to time.

               (b)  In the event of any Change in Control, the Option shall
become immediately fully exercisable to the extent of 100% of the Option Shares.
Notwithstanding the foregoing, the exercisability of the Option shall not be so
accelerated if and to the extent such Option, in connection with the Change in
Control, remains outstanding, or is assumed by the surviving corporation (or
parent thereof) or substituted with an award with substantially the same terms
by the surviving corporation (or parent thereof).

               The determination of whether a substituted award has
substantially the same terms as the Option shall be made by the Administrator,
and its determination shall be final, binding and conclusive. If the Company and
the other party to the transaction constituting a Change in Control agree that
such transaction is to be treated as a "pooling of interests" for financial
reporting purposes, and if such transaction in fact is so treated, then the
acceleration of exercisability shall not occur to the extent that the Company's
independent accountants and such other party's independent accountants
separately determine in good faith that such acceleration would preclude the use
of "pooling of interests" accounting.

               (c)  Notwithstanding the provisions of Section 3(a) above, the
Option shall become immediately exercisable to the extent of 100% of the Option
Shares upon the death or Disability of Optionee.

         4.    Exercises.
               ---------

               (a)  This Option, to the extent exercisable as provided in
Section 3, may be exercised by Optionee by delivery to the Company of (i) an
Exercise Notice in the form attached to this Agreement as Annex A, appropriately
completed and duly executed and dated by Optionee, (ii) payment in full of the
Exercise Price for the number of Option Shares which Optionee is purchasing
hereunder, and (iii) payment in full to the Company of any amounts required to
be paid pursuant to Section 4(c) below.

                                      I-4
<PAGE>

               (b)  The Exercise Price shall be payable (i) in cash or a cash
equivalent, (ii) by transfer to the Company of Common Shares, which shall be
valued at Fair Market Value on the date of exercise, that have been owned by
Optionee for the requisite period necessary to avoid a charge to the Company's
earnings, (iii) by cancellation of any indebtedness of the Company to Optionee
or (iv) by a combination of any of the foregoing methods of payment. In
addition, payment of the Exercise Price may be effected in whole or in part with
monies received from the Company at the time of exercise as a compensatory cash
payment or to the extent that the Exercise Price exceeds the par value of the
Option Shares, with monies borrowed from the Company in accordance with Section
9.5 of the Plan. The requirement of payment in cash shall be deemed satisfied if
Optionee shall have made arrangements satisfactory to the Company with a broker
who is a member of the National Association of Securities Dealers, Inc. to sell
on the date of exercise a sufficient number of the Common Shares being purchased
so that the net proceeds of the sale transaction will at least equal the
aggregate Exercise Price, plus interest at the applicable federal rate for the
period from the date of exercise to the date of payment, and pursuant to which
the broker undertakes to deliver the aggregate Exercise Price, plus such
interest, to the Company not later than the date on which the sale transaction
will settle in the ordinary course of business. If the Exercise Price is paid by
transfer to the Company of Common Shares that were originally acquired by
Optionee pursuant to the exercise of an Incentive Stock Option and that have not
been owned by the Optionee for more than one year prior to the date of exercise
and for more than two years from the date on which the option was granted, the
Common Shares so transferred will not be treated for tax purposes as shares
acquired pursuant to the exercise of an Incentive Stock Option. The
Administrator may, in its sole and absolute discretion, refuse any tender of
shares of Stock, in which case it shall promptly notify the Optionee and return
to the Optionee any shares tendered.

               (c)  If the Company is required to withhold any federal, state,
local or foreign tax in connection with an exercise of the Option, it shall be a
condition to the exercise that Optionee pay the tax or make provisions that are
satisfactory to the Company for the payment thereof as set forth in Section 5
hereof.

               (d)  Following the receipt by the Company of the Exercise Notice
and payment referred to above and upon satisfaction of all conditions to the
exercise of the Option, the Company will issue and deliver to Optionee a stock
certificate or certificate(s) evidencing the Option Shares; provided, however,
that the Company will not be obligated to issue a fraction or fractions of a
Common Share and, in the discretion of the Administrator, may eliminate such
fraction or fractions or may pay to Optionee, in cash or by check, the fair
market value of any fraction or fractions of an Option Share, which fair market
value shall be determined by the Administrator.

         5.    Withholding.
               -----------

               (a)  The Company shall be entitled to require as a condition of
delivery of any Option Shares upon exercise of any Option that the Optionee
agree to remit, at the time of such delivery or at such later date as the
Company may determine, an amount sufficient to satisfy all federal, state and
local withholding tax requirements relating thereto, and Optionee agrees to take
such other action required by the Company to satisfy such withholding
requirements.

               (b)  With the consent of the Administrator, and in accordance
with any rules and procedures from time to time adopted by the Administrator,
Optionee may elect to satisfy his or her obligations under Section 5(a) above by
directing the Company to withhold a portion of Common

                                      I-5
<PAGE>

Shares otherwise deliverable (a "Withholding Right") or tendering other shares
of the Stock which are already owned by Optionee which in all cases have a Fair
Market Value on the Tax Date equal to the amount of taxes to be paid by such
method.

               (c)    To exercise a Withholding Right, the Optionee must follow
the election procedures set forth below, together with such additional
procedures and conditions set forth in this Option Agreement or otherwise
adopted by the Administrator:

                   (i)    the Optionee must deliver to the Company his or her
         written notice of election (the "Election") and specify whether all or
         a stated percentage of the applicable taxes will be paid in accordance
         with Section 5(b) above and whether the amount so paid shall be made in
         accordance with the "flat" withholding rates for supplemental wages or
         as determined in accordance with Optionee's Form W-4 (or comparable
         state or local form);

                  (ii)    unless disapproved by the Administrator as provided
         in Subsection (iii) below, the Election once made will be irrevocable;
         and

                 (iii)    no Election is valid unless the Administrator has the
         right and power, in its sole discretion, with or without cause or
         reason therefor, to consent to the Election, to refuse to consent to
         the Election, or to disapprove the Election; and if the Administrator
         has not consented to the Election on or prior to the Tax Date, the
         Election will be deemed approved.

         6.    Termination of Option. The Option shall terminate on the earliest
               ---------------------
of the following dates:

               (a)    90 days after the date on which Optionee ceases to be a
         consultant to the Company, a Parent or a Subsidiary unless he or she
         ceases to be such a consultant in a manner described in (b) or (c)
         below.

               (b)    [30 days after] [The date upon which] Optionee's service
         as a consultant is terminated for Cause.

               (c)    One year after the date on which Optionee's service is
         terminated as a result of Optionee's death or Disability.

In the event that Optionee commits an act that the Administrator determines to
have been intentionally committed and materially inimical to the interests of
the Company, a Parent or any Subsidiary, the Option shall terminate as of the
time of the commission of that act, notwithstanding any other provision of this
Agreement.

         7.    No Transfer of Option. The Option may not be transferred except
               ---------------------
by will or the laws of descent and distribution and may not be exercised during
the lifetime of Optionee except by Optionee or Optionee's guardian or legal
representative acting on behalf of Optionee in a fiduciary capacity under state
law and court supervision.

         8.    Limitations on Exercise of Option. Notwithstanding any other
               ---------------------------------
provision of this Agreement, no shares of Stock shall be purchased or sold
hereunder unless and until (a) any then

                                      I-6
<PAGE>

applicable requirements of state or federal laws and regulatory agencies shall
have been fully complied with to the satisfaction of the Company and its counsel
and (b) if required to do so by the Company, the Optionee shall have executed
and delivered to the Company a letter of investment intent in such form and
containing such provisions as the Board or Committee may require.

         9.    Adjustments.
               -----------

               (a)  The Administrator may make or provide for such adjustments
in the number and kind of Option Shares (including shares of another issuer) and
in the Exercise Price, as the Administrator may in good faith determine to be
equitably required in order to prevent dilution or expansion of the rights of
Optionee that otherwise would result from (a) any stock dividend, stock split,
combination of shares, recapitalization or other change in the capital structure
of the Company, or (b) any merger, consolidation, spin-off, spin-out, split-off,
split-up, reorganization, partial or complete liquidation or other distribution
of assets, issuance of warrants or other rights to purchase securities or any
other corporate transaction or event having an effect similar to any of the
foregoing.

               (b)  In the event of any such transaction or event, the
Administrator may provide in substitution for the Option such alternative
consideration as it may in good faith determine to be equitable under the
circumstances and may require in connection therewith the surrender of the
Option.

         10.   No Right to Continue as a Consultant. No provision of this
               ------------------------------------
Agreement shall confer upon Optionee any right to continue to be engaged as a
consultant to the Company, a Parent or any Subsidiary or limit in any way
whatsoever any right that the Company, a Parent or any Subsidiary may have to
terminate such service of Optionee at any time.

         11.   No Rights as a Stockholder. The holder of this Option shall not
               --------------------------
be, nor have any of the rights or privileges of, a holder of Common Shares in
respect of any Option Shares unless and until certificates representing such
shares have been issued by the Company to such holder.

         12.   Required Holding Period. Notwithstanding the provisions of
               -----------------------
Section 3(b), to the extent necessary for the Option, its exercise or the sale
of Option Shares acquired thereunder to be exempt from Section 16(b) of the
Exchange Act, (a) such Option shall be held at least six months following the
Date of Grant, or (b) at least six months shall elapse from the Date of Grant to
the date of disposition of the Option Shares acquired upon exercise of the
Option.

         13.   Severability. In the event that one or more of the provisions of
               ------------
this Agreement shall be invalidated for any reason by a court of competent
jurisdiction, any provision so invalidated shall be deemed to be separable from
the other provisions hereof, and the remaining provisions hereof shall continue
to be valid and fully enforceable.

         14.   Governing Law. This Agreement is made under, and shall be
               -------------
construed in accordance with, the laws of the State of Illinois without regard
to the choice of law provisions thereof.

                                      I-7
