      become irrevocable) after the Date of Termination all such Accrued Obligations;





(ii)  the
      Company shall, for a period of one year after the Date of Termination continue
      to pay the Base Salary and benefits to Executive and/or Executive’s family at
      least equal to those which would have been provided to them in accordance with
      the plans, programs, practices and policies described in Section 4(b)(iii)
      including health insurance and life insurance, in accordance with the most
      favorable plans, practices, programs or policies of the Company and its
      subsidiaries in effect on the Date of Termination; provided that the Company
      shall not be required to provide a benefit or benefits under this Section (other

(iii)  in
      addition to the foregoing, (A) all of Executive’s unvested Employee Options or
      Performance Options shall immediately vest, and (B) all of Executive’s options
      (whether arising from the Employee Options or the Performance Option) as of
      the

(f)  Good
      Reason - Change-in-Control .
      If
      Executive shall terminate his employment within six (6) months of a
      Change-in-Control:





(i)  if
      the
      termination is accompanied by any element of Good Cause set forth in Section
      5(c
      )(i) - (vi) also being present, then the Company shall pay to Executive in
      a
      lump sum in cash within thirty (30) days (or such longer period necessary for
      the release referred to in Section 9(f) to become irrevocable) after the Date
      of
      Termination all such Accrued Obligations plus three times (3x) less $1.00 of
      an
      amount equal to Executive’s average base salary and incentive payments paid to
      the Executive in the prior three years or such lesser period of time that
      Executive has been employed by the Company; in the event such termination is
      not
      accompanied by Good Cause, then the Executive shall be paid the same amount
      immediately set forth above but the multiplier in the prior sentence shall
      be
      one and one-half times (1.5x), not three (3x) times ; and





(ii)  in
      addition to the forgoing, (A) all of Executive’s unvested Employee Options or
      Performance Options shall immediately vest, and (B) all of Executive’s options
      (whether arising from the Employee Options or the Performance Option) as of
      the
      Date of Termination shall remain exercisable for two (2) years after such Date
      of Termination.





(g)  Change-in-Control .

      Options .
      With
      regard to Employee options granted to Executive pursuant to Section 4(b)(iv),
      100% of such options shall vest immediately prior to the completion of a
      Change-in-Control, unless at the time of such Change-in-Control transaction,
      the
      unvested options are substituted or continued by the acquirer, regardless of
      whether Executive’s employment is terminated.





(ii)  Performance

      With
      regard to Performance Options granted under Section 4(b)(v), such options shall
      vest as follows:





(1)  50%
      shall
      vest immediately if at anytime after the occurrence of a Change-in-Control
      or
      the announcement of a Change-in-Control the price per share of the Company’s
      common stock equals or exceeds $1.80; and





(2)  100%
      shall vest immediately if at anytime after the occurrence of a Change-in-Control
      or the announcement of a Change-in-Control the price per share of the Company’s
      common stock equals or exceeds $2.35.




9




Upon
                the completion of a Change-in-Control, any such Performance Options
                that
                remain unvested after the application of provisions (1) and (2) of
                this
                Section 6(g)(ii) shall expire.





7.  Non-exclusivity
      of Rights .
      Nothing
      in this Agreement shall prevent or limit Executive’s continuing or future
      participation in any benefit, bonus, incentive or other plans, programs,
      policies or practices, provided by Company, the Company or any of their
      respective subsidiaries and for which Executive may qualify, nor shall anything
      herein limit or otherwise affect such rights as Executive may have under any
      stock option, restricted stock or other agreements with Company, the Company
      or
      any of their respective subsidiaries. Amounts which are vested benefits or
      which
      Executive is otherwise entitled to receive under any plan, policy, practice
      or
      program of Company, the Company or any of their respective subsidiaries at
      or
      subsequent to the Date of Termination shall be payable in accordance with such
      plan, policy practice or program.





8.  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
      set-off, counterclaim, recoupment, defense or other claim, right or action
      which
      the Company may have against Executive or others. In no event shall Executive
      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.





9.  Certain
      Covenants of Executive .





(a)  As
      used
      in Section 9 and Section 10, the Company shall include the Company and each
      corporation, partnership, or other entity that controls the Company, is
      controlled by the Company, or is under common control with the Company (in
      each
      case “control” meaning the direct or indirect ownership of 50% or more of all
      outstanding equity interests).





(b)  While
      Executive is employed by the Company and, following the termination of
      Executive’s employment for any reason, until the first anniversary of the Date
      of Termination, Executive will not, directly or indirectly:





(i)  employ
      or
      attempt to employ any director, officer, or employee of the Company, or
      otherwise interfere with or disrupt any employment relationship (contractual
      or
      other) of the Company;





(ii)  solicit,
      request, advise, or induce any present or potential customer (defined by those
      companies from which the Company has either solicited business or have prepared
      marketing proposals for the solicitation of business within the past 12 months
      prior the Date of Termination), supplier, or other business contact of the
      Company to cancel, curtail, or otherwise change its relationship with the
      Company; or





(iii)  publicly
      criticize or disparage in any manner or by any means the Company or its
      management, policies, operations, products, services, practices, or
      personnel.





10


(c)  Executive
      hereby acknowledges and agrees that all non-public information and data of
      the
      Company, including without limitation that related to product and service
      formulation, customers, pricing, sales, and financial results (collectively,
      “Trade Secrets”) are of substantial value to the Company, provide it with a
      substantial competitive advantage in its business, and are and have been
      maintained in the strictest confidence as trade secrets. Except as permitted
      by
      the Board, or as appropriate in the performance of Executive’s duties in the
      normal course of business, Executive shall not at any time disclose or make
      accessible to anyone any Trade Secrets.





(d)  Executive
      acknowledges and agrees that this Section 9 and each provision hereof are
      reasonable and necessary to ensure that the Company receives the expected
      benefits of this Agreement and that violation of this Section will harm the
      Company to such an extent that monetary damages alone would be an inadequate
      remedy. Consequently, in the event of any violation or threatened violation
      by
      Executive of any provision of this Section, the Company shall be entitled to
      an
      injunction (in addition to all other remedies it may have) restraining Executive
      from committing or continuing such violation. If any provision or application
      of
      this Section is held unlawful or unenforceable in any respect, this Section
      shall be revised or applied in a manner that renders it lawful and enforceable
      to the fullest extent possible.





(e)  Upon
      termination of Executive’s employment for any reason, Executive covenants to
      resign from the Board effective no later than the Termination Date.





(f)  Prior
      to
      the payment of any amount pursuant to Section 6, Executive shall have executed
      the release in the form set forth as Exhibit A (with the blanks appropriately
      filled in) and such release shall have become irrevocable. The release shall
      exclude those claims related to Executive’s vested Employee Options, vested
      Performance Options, Accrued Obligations, the obligations in paragraph 9(g),
      and
      any rights of indemnification from third party claims that existed prior to
      Executive’s termination.





(g)  Upon
      termination of the Executive’s employment for any reason, the Company shall not
      publicly criticize or disparage in any manner or by any means the Executive.
      Upon termination of the Executive’s employment for any reason, Executive shall
      not publicly criticize or disparage in any manner or by any means the Company.





10.  Creations .





(a)  Executive
      hereby transfers and assigns to the Company (or its designee) all right, title,
      and interest of Executive in and to every idea, concept, invention, and
      improvement (whether patented or not) conceived by Executive and all copyrighted
      or copyrightable matter created by Executive during the Term hereof that relates
      to the Company’s business (collectively, “Creations”). Executive shall
      communicate promptly and disclose to the Company, in such form as the Company
      may request, all information, details, and data pertaining to each Creation.
      Every copyrightable Creation, regardless of whether copyright protection is
      sought or preserved by the Company, shall be “work for hire” as defined in 17
      U.S.C. § 101 and the Company shall own all rights in and to such matter
      throughout the world, without the payment of any royalty or other consideration
      to Executive or anyone claiming through Executive.





11


(b)  All
      right, title, and interest in and to any and all trademarks, trade names,
      service marks, and logos adopted, used, or considered for use by the Company
      during Executive’s employment (whether or not developed by Executive) to
      identify the Company’s products or services (collectively, the “Marks”) and all
      other materials, ideas, or other property conceived, created, developed,
      adopted, or improved by Executive solely or jointly during Executive’s
      employment by the Company and relating to its business, shall be owned
      exclusively by the Company. Executive shall not have, and will not claim to
      have, any right, title, or interest of any kind in or to the Marks or such
      other
      property.





(c)  Executive
      shall execute and deliver to the Company such formal transfers and assignments
      and such other documents as the Company may request to permit the Company (or
      its designee) to file and prosecute such registration applications and other
      documents it deems useful to protect its rights under this Agreement. Any idea,
      copyrightable matter, or other property relating to the Company’s business and
      disclosed by Executive prior to the first anniversary of the Date of Termination
      shall be deemed to be governed hereby unless proved by Executive to have been
      first conceived and made after the Date of Termination.





(d)  Executive
      acknowledges and understands that this Agreement does not apply to any invention
      that qualifies fully under the provisions of the Illinois Employee Patent Act,
      765 ILCS 1060 seq. (i.e., an invention for which no Company equipment, supplies,
      facility, or trade secret information was used and which was developed entirely
      on the employee’s own time and (1) does not relate to Company business and (2)
      does not result from any work performed by Executive for the
      Company).





11.  Successors .





(a)  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)  This
      Agreement shall inure to the benefit of and be binding upon Company and the
      Company and their respective successors and assigns.





(c)  The
      Company will require any successor (whether direct or indirect, by purchase,
      merger, consolidation or otherwise) to all or substantially all of its business
      and/or assets 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. As used in this Agreement, “Company”
shall mean as hereinbefore defined and any successor to its business and/or
      assets as aforesaid which assumes and agrees to perform this Agreement by
      operation of law, or otherwise.





12.  Arbitration .
      Any
      controversy or claim arising out of or relating to this Agreement, or the breach
      of this Agreement, other than claims for specific performance or injunctive
      relief pursuant to Section 9, shall be settled by arbitration before one
      arbitrator conducted in Chicago, Illinois, and judgment upon any award rendered
      by the arbitrator may be entered in any Illinois state or United States federal
      court sitting in Chicago, Illinois.





12


13.  Tax
      and Legal Considerations .





(a)  Golden
      Parachute Gross-Up Payment .
      In the
      event it shall be determined that any payments due under this Agreement would
      be
      subject to an excise tax imposed by Section 4999 of the Code, or any interest
      or
      penalties (an “Excise Tax”), then Executive shall be entitled to receive an
      additional payment (a “Gross-Up Payment”) in an amount such that after payment
      by Executive of Federal and state income tax and Excise Tax imposed upon the
      Gross-Up Payment, Executive will have received an amount of the Gross-Up Payment
      equal to the Excise Tax imposed upon such payments. All determinations required
      to be made under this Section 13(a), including whether and when a Gross-Up
      Payment is required and the amount of such Gross-Up Payment and the assumptions
      to be utilized in arriving at such determination, shall be made by the public
      accounting firm that is retained by the Company as of the date immediately
      prior
      to a Change-in-Control of the Corporation (the “Accounting Firm”) which shall
      provide detailed supporting calculations both to the Corporation and Executive.
      Any Gross-Up Payment, as determined pursuant to this Section 13(a), shall be
      paid by the Company to Executive within ten (10) days of the determination.
      The
      determination by the Accounting Firm shall be binding upon the Corporation
      and
      Executive.





(b)  Deferred
      Compensation Restrictions .
      It is
      intended that any amounts payable under this Agreement shall comply with the
      provisions of Section 409A of the Internal Revenue Code of 1986, as amended
      (the
“Code”), and the treasury regulations promulgated thereunder. To avoid any
      penalties or excise tax on Executive as imposed by Section 409A, required
      payments to Executive upon termination of his employment shall be distributed
      on
      the later of (i) the dates specified in this Agreement or (ii) six (6) months
      after Executive’s Date of Termination. The term “termination of employment” and
      other similar terms used in this Agreement shall be construed to have the same
      meaning as is given to the term “Separation from Service” in Section 409A.
      Executive and the Company agree to cooperate to make such other amendments
      to
      the terms of this Agreement as may be necessary to avoid the imposition of
      penalties and additional taxes under Section 409A of the Code.





14.  Miscellaneous .





(a)  This
      Agreement shall be governed by and construed in accordance with the laws of
      the
      State of Illinois, without reference to principles of conflict of laws. The
      captions of this Agreement are not part of the provisions hereof and shall
      have
      no force or effect. This Agreement may not be amended or modified otherwise
      than
      by a written agreement executed by the parties hereto or their respective
      successors and legal representatives.

      Retirement Income Security Act, and any other local, state or federal statutes.
      Executive acknowledges that this Release includes all claims Executive is
      legally permitted to release and as such does not apply to any claim for
      reemployment benefits, nor does it preclude Executive from filing a charge
      of
      discrimination with the state Department of Human Rights or the federal Equal
      Employment Opportunity Commission although Executive would not be able to
      recover any damages if Executive filed such a charge. This Release includes
      but
      is not limited to all claims relating to Executive’s employment and the
      separation of Executive’s employment. This Release Agreement shall be binding
      upon Executive and upon his heirs, administrators, representatives, executors,
      successors and assigns. Notwithstanding anything to the contrary contained
      herein, in no event shall this Release Agreement constitute a release by
      Executive of his rights with respect to accrued benefits to which he would
      otherwise be entitled under any of the Company’s employee benefit plans,
      programs or other employee benefit arrangements (excluding any severance plans
      or arrangements).
