     before the Expiration Date.

          (b) If the Optionee ceases to be an Employee because of death, the
     Optionee's vested Options shall be exercised, if at all, by the person or
     entity (including the Optionee's estate) that has obtained the Optionee's
     rights under the Option by will or under the laws of descent and
     distribution, at any time before the Expiration Date.

     Option upon or immediately before the effectiveness of such event.

          (f) Notwithstanding anything else in this Agreement to the contrary,
     in no event shall the Optionee exercise this Option until the Company,
     pursuant to the terms of its restated certificate of incorporation, has
     authorized for issuance the shares issuable upon exercise of this Option.

     6.   Exercise of Option.
          ------------------

          (a) During the Optionee's lifetime, this Option shall be exercisable
     only by the Optionee or his or her legal representative or guardian.  In
     the event of the Optionee's death, this Option shall be exercisable by the
     person or entity (including the Optionee's estate) that has obtained the
     Optionee's rights under the Option by will or under the laws of descent and
     distribution.

<PAGE>

     representations, covenants, and other undertakings that the Company may
     prescribe pursuant to the VSRA, the Equity Sales Program of the Partner
     Compensation Program, or any other source, or to satisfy securities laws
     and regulations or other requirements, and (3) a personal, certified or
     bank cashier's check payable to the order of the Company in an amount equal
     to the full purchase price of the Option Shares to be purchased.

          (c) Notwithstanding the foregoing, if permitted by the Committee,
     payment of such purchase price may be made in (i) previously owned whole
     shares of Stock (for which the Optionee has good title, free and clear of
     all liens and encumbrances), having a value determined by the closing price
     of a share of Stock on the NASDAQ National Market System (the "NASDAQ
     Price") on the date of exercise, the total amount being equal to the
     aggregate purchase price of the Option Shares to be purchased, (ii) by
     authorizing the Company to retain whole shares having a value determined by
     the NASDAQ Price on the date of exercise, the total amount being equal to
     the aggregate purchase price of the Option Shares to be purchased, which
     whole shares would otherwise be issuable upon exercise of the Option, (iii)
     in cash by a broker-dealer to whom the Optionee has submitted an
     irrevocable notice of exercise, or (iv) a combination of cash, (i) and
     (ii).

          (d) Upon consent of the Committee, the Optionee may elect to defer
     delivery of the Option Shares by notifying the Committee and acting in
     accordance with rules and procedures established by the Committee.  Prior
     to delivery of the deferred Option Shares to the Optionee: (i) the Option
     Shares may not be sold, assigned, transferred, pledged or otherwise
     encumbered, other than by will or the laws of descent and distribution;
     (ii) the Optionee shall have none of the rights of a shareholder with
     respect to the Option Shares; and (iii) nothing contained in this Agreement
     shall give any rights to the Optionee that are greater than those of a
     general creditor of the Company.


     7.   Modification of Option.
          ----------------------

     At any time and from time to time the Committee may modify, extend or renew
this Option, provided that no such modification, extension or renewal shall
impair in any respect the benefit of the Option to the Optionee without the
consent of the Optionee.

     8.   Stockholder Rights.
          ------------------

     The Optionee shall have none of the rights of a stockholder with respect to
the Option Shares until: (i) the transfer of such shares to the Optionee has
been duly recorded on the stock transfer books of the Company upon the exercise
of the Option; and (ii) the Optionee shall execute and deliver to the Company,
in the form prescribed by the Company, either a counterpart of the VSRA or an
agreement under which the Optionee adopts and agrees to be bound by the VSRA.
The certificates representing the Option Shares purchased shall bear the legends
provided in the VSRA, the Partner Compensation Program, and other required
legends.

     9.   Incentive Stock Option.
          ----------------------

                                      20
<PAGE>

     If the Notice of Grant states that the Option is an incentive stock option,
this Option is intended to be and shall for all purposes be treated as an
incentive stock option under Section 422 of the Internal Revenue Code (the
"Code").  To the extent that the aggregate Fair Market Value (as of the Date of
Grant) of the Option Shares issuable under all Options (including this Option)
granted to an individual which are exercisable for the first time by such
individual during any calendar year exceeds $100,000, such Options shall be
treated as Options that are not "incentive stock options" under the Code.

     In the event that the Committee modifies the vesting of the Option or some
other action occurs which affects the tax-advantaged treatment of the Option,
negatively or positively, or the laws relating to the Option change, this Option
shall be treated as an incentive stock option to the maximum extent allowed by
law.

     10.  Other Documents.
          ---------------

     The Optionee acknowledges receipt of copies of the Plan, the VSRA and the
Partner Compensation Program, and agrees to all of the respective terms,
conditions, restrictions and limitations contained therein.

     11.  Stockholder Approval of Plan.
          ----------------------------

     This Option is subject to the approval of the Plan by the stockholders of
the Company at the 1998 annual meeting of the stockholders of the Company or an
adjournment thereof.  If such approval is not granted, then this Option is void
in its entirety, regardless of any vesting which shall have occurred hereunder.
Until approval of the Plan by the stockholders of the Company, no exercise of
Options shall be allowed.

     12.  Notices.
          -------

     All notices by one party to the other under this Agreement shall be in
writing.  Any notice under this Agreement to the Committee or to the Company
shall be addressed to the Company at Suite 3000, 875 N. Michigan Avenue,
Chicago, Illinois 60611, and any notice to the Optionee shall be addressed to
the Optionee at the address listed on the Notice of Grant.  If mailed by United
States mail, properly addressed and proper postage prepaid or if sent by
recognized overnight courier service, notice shall be effective on the date of
mailing or delivery to such courier.  If served personally, notice shall be
effective as of the date of delivery to the address of the party to whom the
notice is addressed.  If the effective date as provided above is not a business
day, the effective date shall be the next regular business day.  Either party
may at any time notify the other in writing of a new address for service of
notice upon that party.

     13.  Severability.
          ------------

     If any provision of this Agreement for any reason should be found by any
arbitrator or court of competent jurisdiction to be invalid, illegal or
unenforceable, in whole or in part, such declaration shall not affect the
validity, legality, or enforceability of any remaining provision or portion
hereof, which remaining provision or portion shall remain in full force and
effect as if this Agreement had been adopted with the invalid, illegal or
unenforceable provision or portion eliminated.

                                      21

     14.  Agreed Forum.
          ------------

     All acts required to be performed by the Optionee hereunder shall be deemed
to be performed in Chicago, Cook County, Illinois, and the Optionee hereby
submits to the jurisdiction of any state or Federal court located in Chicago,
Illinois and waives any and all objections to the jurisdiction of such courts
and the venue of any action brought therein.

     15.  Arbitration.
          -----------

     In the event of a dispute relating to this Stock Option Agreement, the
parties agree to attempt in good faith to resolve the dispute among themselves.
If this is unsuccessful, the parties shall attempt to mutually agree on an
alternative dispute resolution mechanism.  If the parties cannot so agree on an
alternative dispute resolution mechanism, then the parties shall submit this
dispute to binding arbitration under the Commercial Rules of the American
Arbitration Association.  The parties shall each bear one-half (1/2) of the
costs of the alternative dispute resolution mechanism.

In the event arbitration is chosen, each party shall select an arbitrator of its
choice within 20 days of the giving or receipt of notice of arbitration.  The
two, in turn, shall choose a third presiding arbitrator.  If the two shall be
unable to agree upon the presiding arbitrators or if any party fails or refuses
to appoint an arbitrator, the appointing authority shall have the power to make
an appointment.

The award of the arbitrators, which shall be in writing and furnished within
thirty days of the last day of the hearing, shall be final and binding upon the
parties and neither party shall appeal the award to any court.  Judgement for
enforcement of the award of the arbitrators may be entered in any court having
jurisdiction thereof.  The parties acknowledge that this provision and any award
rendered pursuant to it shall be governed by the federal Uniform Arbitration
Act.

     16.  Equitable Relief.
          ----------------

     The Company shall be entitled to enforce the terms and provisions of this
Agreement by an action for injunction or specific performance or an action for
damages or all of them, or may be made the subject of the arbitration
proceedings described in the preceding section.

     17.  Applicable State Law.
          --------------------

     This Agreement shall be governed by and construed and enforced in
accordance with the laws of the State of Illinois.
