                                 November , 2003

American Stock Transfer & Trust Company
59 Maiden Lane
New York, New York 10038


Ladies and Gentlemen:

In connection with your appointment as Subscription Agent in the transaction
described herein, pursuant to this Subscription Agent Agreement (this
"Agreement"), Cosi, Inc. (the Company), hereby confirms its arrangements with
you as follows:


1.    RIGHTS OFFERING - The Company is offering (the "Rights offering") to
      the holders of shares of its Common Stock, par value $0.01 per share
      ("Common Stock"), on November 24, 2003 (the "Record Date"), the right
      ("Rights") to subscribe for shares of its Common Stock. Each Right
      entitles the holder to subscribe for and purchase a number of shares of
      Common Stock having a value equal to an aggregate of $0.6776, at a
      purchase price per share equal to the lesser of (i) $1.50 and (ii) 85% of
      the weighted average price per share of our common stock as reported on
      the Nasdaq National Market for the 15-trading-day period ending three
      business days prior to December 19, 2003. Except as set forth under
      Paragraphs 8 and 9 below, the Rights shall cease to be exercisable at 5:00
      p.m., New York City time, on December 19, 2003 or such later date of which
      the Company notifies you orally and confirms in writing (the "Expiration
      Date"). One Right is being issued for each share of Common Stock held on
      the Record Date. Rights are evidenced by non-transferable rights
      certificates in registered form ("Rights Certificates"). Each holder of
      Rights Certificate(s) who exercises the holder's right to subscribe for
      all shares of Common Stock that can be subscribed for with the Rights
      evidenced by such Rights Certificate(s) (the "Basic Subscription Right")
      will have the right to subscribe for additional shares of Common Stock, if
      any, available as a result of any unexercised Rights (such additional
      subscription right being referred to hereafter as the "Over-Subscription
      Privilege"). The maximum number of shares for which a holder will be able
      to subscribe pursuant to the Over-Subscription Privilege will equal such
      holder's pro rata share of the total amount of shares of Common Stock
      available for over-subscription. A holder's pro rata share will be based
      upon the total number of shares of Common Stock and warrants to purchase
      shares of Common Stock owned by such holder compared to the total number
      of shares of Common Stock and warrants to purchase shares of Common Stock
      owned by (i) all stockholders who exercised their Over-Subscription
      privilege and (ii) Eric J. Gleacher, Charles G. Phillips, LJCB Nominees
      Pty Ltd and ZAM Holdings, L.P. (collectively, the "Funding Parties"). If
      there is an insufficient number of shares of Common Stock remaining unsold
      after holders have exercised their basic subscription rights to satisfy in
      full all subscriptions received for



                                       1

      additional shares, you will allocate the available shares among the
      holders who exercise their Over-Subscription privilege on a pro rata basis
      according to their respective holdings, up to the amount such holder has
      subscribed for through the exercise of such holder's over-subscription
      privilege. The Rights Offering will be conducted in the manner and upon
      the terms set forth in the Company's Prospectus, relating to the Rights
      Offering, filed with the Securities and Exchange Commission pursuant to
      Rule 424, promulgated under the Securities Act of 1933, as amended, (the
      "Prospectus"), which is incorporated herein by reference and made a part
      hereof as if set forth in full herein.


2.    APPOINTMENT OF SUBSCRIPTION AGENT - You are hereby appointed as
      Subscription Agent to effect the Rights Offering in accordance with the
      Prospectus. Each reference to you in this letter is to you in your
      capacity as Subscription Agent unless the context indicates otherwise.


3.    DELIVERY OF DOCUMENTS - Enclosed herewith are the following, the receipt
      of which you acknowledge by your execution hereof:

      (a)   a copy of the Prospectus;


      (b)   the form of Rights Certificate (with instructions);


      (c)   resolutions adopted by the Board of Directors of the Company in
            connection with the Rights Offering, certified by the secretary of
            the Company; and

      (d)   Notice of Guaranteed Delivery.


      As soon as is reasonably practical, you shall mail or cause to be mailed
      to each holder of Common Stock at the close of business on the Record Date
      a Rights Certificate evidencing the Total Aggregate Share Value for which
      such holder is entitled to subscribe, a Notice of Guaranteed Delivery, a
      Prospectus and an envelope addressed to you. Prior to mailing, the Company
      will provide you with blank Rights Certificates which you will prepare and
      issue in the names of holders of Common Stock of record at the close of
      business on the Record Date and evidencing the Total Aggregate Share Value
      for which they are entitled to subscribe. The Company will also provide
      you with a sufficient number of copies of each of the documents to be
      mailed with the Rights Certificates.


4.    SUBSCRIPTION PROCEDURE -


      (a) Upon your receipt prior to 5:00 p.m., New York City time, on the
      Expiration Date (by mail or delivery), as Subscription Agent, of (ii) any
      Rights Certificate completed and endorsed for exercise, as provided on the
      reverse side of the Rights Certificate (except as provided in paragraph 8
      hereof), and (ii) payment in full of the Subscription Price in U.S. funds
      by check, bank draft or money order payable at par (without deduction for
      bank service charges or otherwise) to the order of American Stock Transfer
      & Trust Company, you shall as soon as practicable after the Expiration
      Date, but after performing the procedures described in subparagraphs (b)
      and (c) below, mail to the subscriber's registered address on the books of
      the Company certificates representing the securities underlying each Unit
      duly subscribed for (pursuant to the Basic Subscription Right and the
      Over-Subscription Privilege) and furnish a list of all such information to
      the Company.


      (b) As soon as reasonably practical following the Expiration Date you
      shall calculate the number of shares of Common Stock to which each
      subscriber is entitled pursuant to the


                                       2

      Over-Subscription Privilege. The Over-Subscription Privilege may only be
      exercised by holders who fully exercise their Basic Subscription Right.
      The maximum amount of shares of Common Stock available pursuant to the
      Over-Subscription Privilege shall equal that number of shares, at a price
      per share equal to the Subscription Price, having a value equal to $7.5
      million reduced by the aggregate value of shares subscribed for pursuant
      to the Basic Subscription Right. Where there are sufficient shares of
      Common Stock remaining unsold, subject to the limitation described above,
      to satisfy all Over-Subscriptions by holders exercising their rights under
      the Over-Subscription Privilege, each holder shall be allotted the number
      of shares of Common Stock, at the Subscription Price, having a value equal
      to the amount subscribed for. If there is an insufficient number of shares
      of Common Stock remaining unsold after holders have exercised their basic
      subscription rights to satisfy in full all subscriptions received for
      additional shares, you will allocate the available shares, subject to the
      limitation described above, among the holders who exercise their
      Over-Subscription privilege on a pro rata basis according to their
      respective holdings, up to the amount such holder has subscribed for
      through the exercise of such holder's over-subscription privilege. Any
      fractional shares of Common Stock to which persons exercising their
      Over-Subscription Privilege would otherwise be entitled pursuant to such
      allocation shall be rounded down to the next whole share of Common Stock.

      (c) Upon calculating the number of shares of Common Stock to which each
      subscriber is entitled pursuant to the Over-Subscription Privilege and the
      amount overpaid, if any, by each subscriber, you shall, as soon as
      practicable, furnish a list of all such information to the Company.

      (d) Upon calculating the number of shares of Common Stock to which each
      subscriber is entitled pursuant to the Over-Subscription Privilege and
      assuming payment for the additional shares of Common Stock subscribed for
      has been delivered, you shall mail, as contemplated in subparagraph (a)
      above, the certificates representing the additional securities which the
      subscriber has been allotted. If a lesser number of shares of Common Stock
      is allotted to a subscriber under the Over-Subscription Privilege than the
      subscriber has tendered payment for, you shall remit the difference to the
      subscriber without interest or deduction at the same time as certificates
      representing the securities allotted pursuant to the Over-Subscription
      Privilege are mailed.

      (e) Funds received by you pursuant to the Basic Subscription Right and the
      Over-Subscription Privilege shall be held by you in a segregated account.
      Upon mailing certificates representing the securities and refunding
      subscribers for additional shares of Common Stock subscribed for but not
      allocated, if any, you shall promptly remit to the Company all funds
      received in payment of the Subscription Price for shares of Common Stock
      sold in the Rights Offering.


5.    DEFECTIVE EXERCISE OF RIGHTS; LOST RIGHTS CERTIFICATES - The Company shall
      have the absolute right to reject any defective exercise of Rights or to
      waive any defect in exercise. Unless requested to do so by the Company,
      you shall not be under any duty to give notification to holders of Rights
      Certificates of any defects or irregularities in subscriptions.
      Subscriptions will not be deemed to have been made until any such defects
      or irregularities have been cured or waived within such time as the
      Company shall determine. You shall as soon as practicable return Rights
      Certificates with the



                                       3


      defects or irregularities which have not been cured or waived to the
      holder of the Rights. If any Rights Certificate is alleged to have
      been lost, stolen or destroyed, you should follow the same procedures
      followed for lost stock certificates representing Common Stock you use in
      your capacity as transfer agent for the Company's Common Stock.



6.    LATE DELIVERY - If prior to 5:00 p.m., New York City time, on the
      Expiration Date you receive (i) payment in full of the Subscription Price
      for shares of Common Stock being subscribed for and (ii) a guarantee
      notice substantially in the form of the Notice of Guaranteed Delivery
      delivered with the Rights Certificate, from a financial institution having
      an office or correspondent in the United States, or a member firm of any
      registered United States national securities exchange or of the National
      Association of Securities Dealers, Inc. stating the certificate number of
      the Rights Certificate relating to the Rights, the name and address of the
      exercising subscriber, the number of Rights represented by the Rights
      Certificate held by such exercising subscriber, the aggregate value of
      shares of Common Stock being subscribed for pursuant to the Rights and
      guaranteeing the delivery to you of the Rights Certificate evidencing such
      Rights within three NASDAQ National Market ("NNM") trading days following
      the date of the Notice of Guaranteed Delivery, then the Rights may be
      exercised even though the Rights Certificate was not delivered to you
      prior to 5:00 p.m., New York City time, on the Expiration Date, provided
      that within three NNM trading days following the date of the Notice of
      Guaranteed Delivery you receive the properly completed Rights Certificate
      evidencing the Rights being exercised, with signatures guaranteed if
      required.



7.    DELIVERY - You shall deliver to the Company copies of the exercised Rights
      Certificates in accordance with written directions received from the
      Company and shall deliver to the subscribers who have duly exercised
      Rights at their registered addresses certificates representing the
      securities subscribed for as instructed on the reverse side of the Rights
      Certificates.



8.    REPORTS - You shall notify the Company by telephone on and before the
      close of business on each business day during the period commencing 5
      business days after the mailing of the Rights and ending at the Expiration
      Date (and in the case of guaranteed deliveries ending three NNM trading
      days after the Expiration Date) (a "daily notice"), which notice shall
      thereafter be confirmed in writing, of (i) the aggregate value of Rights
      exercised on the day covered by such daily notice, (ii) the aggregate
      value of Rights subject to guaranteed exercises on the day covered by such
      daily notice, (iii) the aggregate value of Rights for which defective
      exercises have been received on the day covered by such daily notice, and
      (iv) the cumulative total of the information set forth in clauses (i)
      through (iii) above. At or before 5:00 p.m., New York City time, on the
      first NNM trading day following the Expiration Date you shall certify in
      writing to the Company the cumulative total through the Expiration Date of
      all the information set forth in clauses (i) through (iii) above. At or
      before 10:00 a.m., New York City time, on the fourth NNM trading day
      following the Expiration Date you will execute and deliver to the Company
      a certificate setting forth the aggregate value of Rights exercised
      pursuant to a Notice of Guaranteed Delivery and as to which Rights
      Certificates have been timely received. You shall also maintain and update
      a listing of holders who have fully or partially exercised their Rights,
      and holders who have not exercised their Rights. You shall provide the
      Company or its designees with such information compiled by you
