EXHIBIT 10.4

                                                              EXECUTION DOCUMENT

                      CHANGE IN CONTROL SEVERANCE AGREEMENT

      THIS CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Agreement") is made and
entered into as of _________________, 2008 (the "Effective Date") by and between
PAUL BOWER ("Executive") and COSI, INC., a Delaware corporation (the "Company").

                                    RECITALS:

      WHEREAS, the Board of Directors of the Company (the "Board") has approved
a Change in Control agreement to provide Executive with certain benefits upon
termination of employment (in certain circumstances).

                                   AGREEMENT:

      NOW, THEREFORE, In consideration of the mutual covenants herein contained
and the continued employment of Employee by the Company, the parties hereto
agree as follows:

      1. Term of Agreement. This Agreement shall commence on the Effective Date
and continue in effect through December 31, 2011; provided, however, the term of
this Agreement shall automatically be extended for one year beyond December 31,
2011 and successive one year periods thereafter, unless, not later than,
September 30, 2010 (for the additional year ending on December 31, 2012) or
September 30 of each year thereafter (for each subsequent extension), the
Company shall have given notice that it does not wish to extend this Agreement
for an additional year, in which event this Agreement shall continue to be
effective until the end of its then remaining term; provided, further, that
notwithstanding any such notice by the Company not to extend, if a Change in
Control shall have occurred during the original or any extended term of this
Agreement, this Agreement shall continue in effect for a period of twelve (12)
months beyond such Change of Control.

      2. Change in Control. No benefits shall be payable hereunder unless there
shall have been a Change in Control of the Company. For purposes of this
Agreement, a "Change in Control" shall mean the date on which the earlier of the
following events occur: (a) the acquisition by any entity, person or group
(other than ZAM Holdings, L.P., LJCB Nominees Pty Ltd., Charles G. Phillips, or
any entity related to any such party) of beneficial ownership, as that term is
defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended, of
more than 50% of the outstanding capital stock of the Company entitled to vote
for the election of directors ("Voting Stock"); (b) the merger or consolidation
of the Company with one or more corporations or other entity as a result of
which the holders of outstanding Voting Stock of the Company immediately prior
to such a merger or consolidation hold less than 60% of the Voting Stock of the
surviving or resulting corporation or any direct or indirect parent corporation
or entity of such surviving or resulting entity; (c) the sale or transfer of all
or substantially all of the property of the Company other than to an entity of
which the Company owns at least 80% of the Voting Stock; or (d) during any
period of twenty-four (24) consecutive months, the individuals who, at the
beginning of such period, constitute the Board of Directors (the "Incumbent
Directors") cease for any reason other than death to constitute at least a
majority thereof; provided, however, that a director who was not a director at
the beginning of such 24-month period shall be deemed to have satisfied such
24-month requirement (and be an Incumbent Director) if such director was elected
by, or on the recommendation of or with the approval of, at least two-thirds of
the directors who then qualified as Incumbent Directors either actually (because
they were directors at the beginning of such 24-month period) or through the
operation of this proviso. Notwithstanding the foregoing, a Change in Control
shall not include any acquisition in which Executive is a member of the
acquiring group or an officer or owner of the acquiring entity.

      3. Termination In Anticipation of or Following a Change in Control. If any
of the events described in Section 2 above constituting a Change in Control
shall have occurred, Executive shall be entitled to the payments and benefits
provided in Section 4(i) below upon the subsequent termination of Executive's
employment with the Company during the term of this Agreement unless such
termination is (A) a result of Executive's death, (B) by Executive without Good
Reason, or (C) by the Company for Disability or for Cause.

            (i) Disability. For purposes of this Agreement, "Disability" shall
      mean Executive's physical or mental disability such that Executive is and
      has been continuously for at least six (6) months unable to perform the
      duties and services required in the performance of Executive's job
      function, and Executive is determined to be eligible or long-term
      disability benefits under the Company's long-term disability benefits plan
      in effect from time to time.

           Any question as to the existence of Executive's Disability upon which
     Executive and the Company cannot agree shall be determined by a qualified
     independent physician selected by Executive and approved by the Company,
     said approval not to be unreasonably withheld. The determination of such
     physician made in writing to the Company and to Executive shall be final
     and conclusive for all purposes of this Agreement.

           (ii) Cause. For purposes of this Agreement, "Cause" shall mean only
     one or more of the following:

                  (A) Executive shall be convicted of, or plead guilty or nolo
            contendere to, a felony;

                  (B) Executive shall willfully neglect or fail to perform the
            duties and services required in the performance of Executive's job
            function, provided that written notice from the Company specifying
            such neglect or failure and a reasonable opportunity to cure, up to
            but not to exceed thirty (30) days, has been delivered to Executive
            and such willful neglect or failure to perform shall continue beyond
            such specified cure period; and/or

                  (C) Executive shall commit any fraud, embezzlement or other
            act of intentional dishonesty against the Company, or shall attempt
            to profit from any transaction in which the Company is a participant
            and in which Executive has an undisclosed interest adverse to the
            Company.

            (iii) Good Reason. Executive shall be entitled to terminate
      employment with Good Reason. For purposes of this Agreement, "Good Reason"
      shall mean the occurrence, without Executive's express written consent, of
      only one or more of the following circumstances unless, in the case of
      Sections 3(iii)(A), (B), (C) or (D) below, such circumstances are fully
      corrected within thirty (30) days after the date of such Notice of
      Termination (as defined in Section 3(iv) below) given in respect thereof.

                  (A) A material diminution in Executive's duties or
            responsibilities from those in effect immediately prior to the
            Change in Control, or the failure by the Company to permit Executive
            to exercise such responsibilities as are consistent with Executive's
            position (as it existed immediately prior to the Change in Control);

                  (B) A reduction in the amount of Executive's annual base
            salary (as in effect on the date hereof and as the same may be
            increased from time to time) or potential annual bonus (at the rate
            in effect on the date hereof and as the same may be increased from
            time to time) or the discontinuation by the Company of all
            healthcare and medical benefits plans in which Executive is
            participating unless the Company has increased Executive's salary to
            offset and compensate Executive for the cost of such discontinued
            healthcare and medical benefits or has otherwise provided
            substantially similar healthcare and medical benefits to Executive;

                  (C) The failure by the Company to make a bi-weekly base salary
            payment to Executive when due in accordance with the Company's
            regular payment practices in effect from time to time;

                  (D) The relocation of the Company's Support Center and
            Executive's office more than fifty (50) miles outside of the City of
            Chicago and the Chicagoland area by decision of the Board, or a
            committee thereof, where Executive was not consulted about or given
            an opportunity to participate in such decision;

                  (E) The failure of the Company to obtain a satisfactory
            agreement from any successor to assume and agree to perform this
            Agreement, as contemplated in Section 5 below; or

                  (F) Any purported termination of Executive's employment by the
            Company which is not effected pursuant to a Notice of Termination
            satisfying the requirements of Section 3(iv) below. For purposes of
            this Agreement, no such purported Termination shall be effective;

            (iv) Notice of Termination. Any purported termination of Executive's
      employment by the Company or by Executive shall be communicated by written
      Notice of Termination to the other party hereto in accordance with Section
      6 hereof. For purposes of this Agreement, a "Notice of Termination" shall
      mean a notice which shall indicate the specific termination provision in
      this Agreement relied upon and shall set forth in reasonable detail (other
      than with respect to a Good Reason termination pursuant to Section
      3(iii)(F) above) the facts and circumstances claimed to provide a basis
      for termination of Executive's employment under the provision so
      indicated.

            (v) Date of Termination. For purposes of this Agreement, "Date of
      Termination" shall mean the date specified in the Notice of Termination,
      which shall not be less than any applicable cure periods specified in
      Section 3 above.

      4. Compensation upon Termination Following a Change in Control.

            (i) Following a Change in Control of the Company, as defined in
      Section 2 above, if Executive's employment by the Company shall be
      terminated (other than for death or Disability) by (i) the Company other
      than for Cause or (ii) Executive with Good Reason, then Executive shall be
      entitled to the following payments and benefits:

                  (A) Commencing on the Date of Termination and continuing for a
            period of nine (9) months ("Compensation Continuation Period"), the
            Company shall continue to pay to Executive his or her base salary
            (as in effect immediately prior to such termination), less
            applicable withholding taxes, payable in bi-weekly installments
            (each a "Salary Continuation Payment"), provided that, if Executive
            is employed by another employer, Salary Continuation Payments made
            after payment of nine (9) bi-weekly Salary Continue Payment
            installments have been made shall be subject to reduction by the
            amount of Executive's then-current bi-weekly base salary.

                  (B) If Employee timely elects to continue medical and health
            benefits pursuant to the Consolidated Omnibus Reconciliation Act of
            1985, as amended ("COBRA"), the Company shall reimburse Executive
            for, or otherwise shall pay, the COBRA premiums from the Date of
            Termination until the earlier of (1) the nine (9) month anniversary
            of the Date of Termination or (2) the date on which Executive
            becomes eligible for healthcare benefits under a health and welfare
            plans offered by another employer. After expiration of the
            Compensation Continuation Period, in accordance with COBRA rules,
            Executive may, at Executive's option and expense, continue such
            coverage at Executive's expense without reimbursement by the
            Company.

                  (C) The Company shall also pay to Executive, no less
            frequently than monthly, all legal fees and expenses reasonably
            incurred by Executive in connection with this Agreement (including
            all such fees and expenses, if any, incurred in contesting or
            disputing the nature of any such termination for purposes of this
            Agreement or in seeking to obtain or enforce any right or benefit
            provided by this Agreement); provided, however, that if a
            determination is made by the arbitrator selected under Section 11
            hereof that Executive acted in a frivolous manner in contesting or
            disputing such termination or seeking to obtain or enforce such
            right or benefit, the Company shall not be liable to pay such legal
            fees or expenses otherwise provided for thereunder and the Company
            shall be entitled to recover from Executive any such amounts so paid
            (either directly or, except as would violate the requirements of
            Section 409A(a)(3) of the Internal Revenue Code of 1986, as amended
            (the "Code"), by setoff against any amounts then owed Executive by
            the Company). Notwithstanding the penultimate sentence of Section 7,
            no reimbursement pursuant to this Section 4(i)(C) shall be paid
            later than the last day of the tenth (10th) calendar year following
            the calendar year in which the applicable statute of limitations for
            breach of contract claims expires or, if later, the last day of the
            calendar year following the calendar year in which there is a
            settlement or other final and nonappealable resolution of the
            related contest or dispute.

            (ii) Notwithstanding the foregoing provisions of this Section 4, if,
      as of the Separation from Service Date, Executive is a Specified Employee,
      then, except to the extent that this Agreement does not provide for a
      "deferral of compensation" within the meaning of Section 409A of the Code,
      the following shall apply:

                  (A) No payments shall be made and no benefits shall be
            provided to Executive, in each case, during the period beginning on
            the Separation from Service Date and ending on the six-month
            anniversary of such date or, if earlier, the date of Executive's
            death.

                  (B) On the first business day of the first month following the
            month in which occurs the six-month anniversary of the Separation
            from Service Date or, if earlier, Executive's death, the Company
            shall make a one-time, lump-sum cash payment to the Executive in an
            amount equal to the sum of (x) the amounts otherwise payable to the
            Executive under this Agreement during the period described in
            Section 4(i)(A) above and (y) the amount of interest on the
            foregoing at the applicable federal rate for instruments of less
            than one year.

     For purposes of this Agreement, "Separation from Service Date" shall mean
the date of the Executive's "separation from service" within the meaning of
Section 409A(a)(2)(i)(A) of the Code and determined in accordance with the
default rules under Section 409A of the Code. "Specified Employee" shall mean a
"specified employee" within the meaning of Section 409A(a)(2)(B)(1) of the Code,
as determined in accordance with the uniform methodology and procedures adopted
by the Company and then in effect.

      5. Successors; Binding Agreement.

            (i) The Company will require any successor (whether direct or
      indirect, by purchase, merger, consolidation or otherwise) to all or
      substantially all of the business and/or assets of the Company to
      expressly assume and agree to perform this Agreement in the same manner
      and to the same extent that the Company is required to perform it. Failure
      of the Company to obtain such assumption and agreement prior to the
      effectiveness of any such succession shall be a breach of this Agreement
      and shall entitle Executive to compensation from the Company in the same
      amount and on the same terms as Executive would be entitled hereunder if
      Executive had terminated Executive's employment with Good Reason following
      a Change in Control, except that for purposes of implementing the
      foregoing, the date on which any such succession becomes effective shall
      be deemed the Date of Termination. As used in this Agreement, "Company"
      shall mean the Company 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.

            (ii) This Agreement shall inure to the benefit of and be enforceable
      by Executive's personal or legal representatives, executors,
      administrators, successors, heirs, distributees, devisees and legatees. If
      Executive should die while any amount would still be payable to Executive
      hereunder if Executive had continued to live, all such amounts, unless
      otherwise provided herein, shall be paid in accordance with the terms of
      this Agreement to Executive's devisee, legatee or other designee or, if
      there is no such designee, to Executive's estate.

      6. Notice. For the purpose of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
deemed to have been duly given (i) upon delivery when delivered by hand, (ii)
the next business day if sent by overnight delivery service by a nationally
recognized courier, or (iii) five (5) days after deposit in the U. S. Mail, as
evidenced by the postmark, if mailed by United States registered or certified
mail, return receipt requested, postage prepaid, addressed as follows:

      To the Company:                      To Executive:
      ---------------                      -------------

      Cosi, Inc.
      1751 Lake Cook Road, 6th Floor       At the notice address set forth
      Deerfield, IL  60015                 under Executive's signature on the
      Attn:  CORPORATE SECRETARY           signature page hereof.

      With a copy to:
      ---------------

      Cosi, Inc.
      1751 Lake Cook Road, 6th Floor
      Deerfield, IL  60015
      Attn:  GENERAL COUNSEL

or to such other address as either party may have furnished to the other in
writing in accordance herewith, except that notice of change of address shall be
effective only upon receipt.

      7. Miscellaneous. No provision of this Agreement may be modified, waived
or discharged unless such waiver, modification or discharge is agreed to in
writing and signed by Executive and such officer as may be specifically
designated by the Board. No waiver by either party hereto at any time of any
breach by the other party hereto of, or compliance with, any conditions or
provision of this Agreement to be performed by such other party shall be deemed
a waiver of similar or dissimilar provisions or conditions at the same or at any
prior or subsequent time. The validity, interpretation, construction and
performance of this Agreement shall be governed by the internal laws of the
State of Illinois, without regard to its conflict of law provisions. This
Agreement is intended to satisfy the requirements of Section 409A of the Code
with respect to amounts subject thereto and shall be interpreted and construed
and shall be performed by the parties consistent with such intent, and the
Company shall have no right to accelerate any payment or the provision of any
benefits under this Agreement or to make or provide any such payment or benefits
if such payment or provision of such benefits would, as a result, be subject to
tax under Section 409A of the Code. Any payments provided for hereunder shall be
paid net of any applicable withholding required under federal, state, local or
other applicable law. Anything in this Agreement to the contrary
notwithstanding, no reimbursement payable to Executive pursuant to any
provisions of this Agreement or pursuant to any plan or arrangement of the
Company covered by this Agreement shall be paid later than the last day of the
calendar year following the calendar year in which the related expense was
incurred, and no such reimbursement during any calendar year shall affect the
amounts eligible for reimbursement in any other calendar year, except, in each
case, to the extent that the right to reimbursement does not provide for a
"deferral of compensation" within the meaning of Section 409A of the Code. The
obligations of the Company under Section 4 shall survive the expiration of the
term of this Agreement. The Recitals set forth above are hereby incorporated
into and made an integral part of this Agreement.

      8. Validity. The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

      9. Counterparts. This Agreement may be executed in several counterparts,
each of which shall be deemed to be an original but all of which together will
constitute one and the same instrument.

      10. Arbitration; Indemnification.

            (i) Any dispute or controversy arising under or in connection with
      this Agreement shall be settled exclusively by arbitration in accordance
      with the rules of the American Arbitration Association then in effect
      applicable to disputes involving an employee and employer. Judgment may be
      entered on the arbitrator's award in any court having jurisdiction. In
      selecting the arbitrator, each of the Company and Executive would select
      one person to serve as an arbitrator, who would have to be accepted by the
      other party (such acceptance not to be unreasonably withheld). Once the
      two arbitrators had been selected, they would select a third arbitrator,
      who would have no affiliation to either of them or either party. And such
      third arbitrator shall be the arbitrator who determines the claim
      presented for arbitration.

            (ii) Following any termination of employment of Executive, the
      Company shall indemnify and hold harmless Executive in accordance with and
      to the fullest extent permitted under the Company's by-laws (as in effect
      prior to the Change in Control), any indemnification agreement between
      Executive and the Company, and applicable law.


      11. Entire Agreement. This Agreement constitutes the entire understanding
between the parties with respect to Executive's severance pay in the event of a
termination of Executive's employment with the Company, superseding all
negotiations, prior discussions and preliminary agreements, written or oral,
concerning said severance pay. Notwithstanding any provision of this Agreement,
the obligations of the Company to make payments to Executive and to make the
arrangements, provided for herein are absolute and unconditional and may not be
reduced by any circumstances, including, without limitation, any set-off,
counterclaim, recoupment, defense or other right which the Company may have
against Executive or any third-party at any time.

      12. Further Action. The Company shall take any further action necessary or
desirable to implement the provisions of this Agreement or perform its
obligations hereunder (including, without limitation, amending any stock option
or stock bonus plan, or any other applicable plan, program or arrangement or
obtaining any necessary consents or approvals in connection therewith).

      IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement
as of the date first above written.
