                                   THE COMPANY

      We are a high quality, premium convenience restaurant company that owns
and operates company restaurants and offers franchises to qualified restaurant
operators. We are focused on knowing our customers and their food and dining
needs. We believe we meet our customers' needs by providing authentic,
innovative savory foods in tasteful upscale settings. We believe our customers
view us as an "affordable luxury." Our restaurant menus feature our authentic
hearth baked crackly crust flatbread, "Cosi Bread," which forms the basis for
savory sandwiches and pizzas and accompanies freshly tossed salads. We also
offer a full line of barista and blender products in addition to freshly brewed
coffees. Our food is ordered at the counter and made fresh with the convenience
of table delivery for eat-in dinner customers. We believe the combination of our
high quality, innovative menu items, inviting customer-oriented atmosphere and
multiple daypart dining convenience drives customer satisfaction and repeat
visits.

      Our principal executive offices are located at 1751 Lake Cook Road, Suite
60015, Deerfield, Illinois 60015 and our telephone number is (847) 597-8800.

                                  RISK FACTORS

      You should carefully consider each of the following risks, as well as all
of the other information contained in this prospectus, before deciding to invest
in our common stock. If any of these risks occurs, our business, financial
condition and results of operations may be adversely affected, the trading price
of our common stock could decline and you may lose part or all of your
investment.

                      Risks Related to Our Growth Strategy

We may not be able to achieve our planned expansion. If we are unable to
successfully open new restaurants, our revenue growth rate and profits may be
reduced.

      To successfully expand our business, we must open new restaurants on
schedule and in a profitable manner. In the past, we have experienced delays in
restaurant openings and we and our franchisees may experience similar delays in
the future. Delays or failures in opening new restaurants could hurt our ability
to meet our growth objectives, which may affect the expectations of securities
analysts and others and thus our stock price. We cannot guarantee that we or our
franchisees will be able to achieve our expansion goals or that new restaurants
will be operated profitably. Further, any restaurants that we or our franchisees
open may not obtain operating results similar to those of our existing
restaurants. Our ability to expand successfully will depend on a number of
factors, many of which are beyond our control. These factors include, but are
not limited to:

            o     locating suitable restaurant sites in new and existing
                  markets;

            o     negotiating acceptable lease terms;

            o     generating positive cash flow from existing and new
                  restaurants;

            o     successful operation and execution in new and existing
                  markets;

            o     recruiting, training and retaining qualified corporate and
                  restaurant personnel and management;


                                        1


            o     attracting and retaining qualified franchisees;

            o     cost effective and timely planning, design and build-out of
                  restaurants;

            o     the reliability of our customer and market studies;


            o     consumer trends;

            o     obtaining and maintaining required local, state and federal
                  governmental approvals and permits related to the construction
                  of the sites and the sale of food and alcoholic beverages;

            o     creating customer awareness of our restaurants in new markets;

            o     competition in our markets, both in our business and in
                  locating suitable restaurant sites;

            o     the cost of our principal food products and supply and
                  delivery shortages or interruptions;

            o     weather conditions; and

            o     general economic conditions.

We must identify and obtain a sufficient number of suitable new restaurant sites
for us to sustain our revenue growth rate.

      We require that all proposed restaurant sites, whether company-owned or
franchised, meet site-selection criteria established by us. We and our
franchisees may not be able to find sufficient new restaurant sites to support
our planned expansion in future periods. We face significant competition from
other restaurant companies and retailers for sites that meet our criteria and
the supply of sites may be limited in some markets. As a result of these
factors, our costs to obtain and lease sites may increase, or we may not be able
to obtain certain sites due to unacceptable costs. Our inability to obtain
suitable restaurant sites at reasonable costs may reduce our growth rate, which
may affect the expectations of securities analysts and others and thus our stock
price.

Our expansion in existing markets can cause sales in some of our existing
restaurants to decline, which could result in restaurant closures.

      As part of our expansion strategy, we and our franchisees intend to open
new restaurants in our existing markets. Since we typically draw customers from
a relatively small radius around each of our restaurants, the sales performance
and customer counts for restaurants near the area in which a new restaurant
opens may decline due to cannibalization, which could result in restaurant
closures. In addition, new restaurants added in existing markets may not achieve
the same operating performance as our existing restaurants.

Our expansion into new markets may present increased risks due to our
unfamiliarity with the area. The restaurants we open in new geographic regions
may not achieve market acceptance.

      Some of our future franchised restaurants and company-owned restaurants
will be located in areas where we have little or no meaningful experience. Those
markets may have different demographic characteristics, competitive conditions,
consumer tastes and discretionary spending patterns than our existing markets
that may cause our new restaurants to be less successful than restaurants in our
existing


                                        2


markets. An additional risk in expansion into new markets is the lack of market
awareness of the Cosi brand. Restaurants opened in new markets may open at lower
average weekly sales volumes than restaurants opened in existing markets and may
have higher restaurant-level operating expense ratios than in existing markets.
Sales at restaurants opened in new markets may take longer to reach average
annual company-owned restaurant sales, if at all, thereby affecting the
profitability of these restaurants.

We may not be able to successfully incorporate a franchising and area developer
model into our strategy.

      We are incorporating a franchising and area developer model into our
business strategy in certain selected markets. We have not used a franchising or
area developer model prior to fiscal 2004 and may not be as successful as
predicted in attracting franchisees and developers to the Cosi concept or
identifying franchisees and developers that have the business abilities or
access to financial resources necessary to open our restaurants or to
successfully develop or operate our restaurants in a manner consistent with our
standards. Incorporating a franchising and area developer model into our
strategy also requires us to devote significant management and financial
resources to support the franchise of our restaurants. Our future performance
will depend on our franchisees' ability to execute our concept and capitalize
upon our brand recognition and marketing. We may not be able to recruit
franchisees who have the business abilities or financial resources necessary to
open restaurants on schedule, or who will conduct operations in a manner
consistent with our concept and standards. Our franchisees may not be able to
operate restaurants in a profitable manner. If we are not successful in
incorporating a franchising or area developer model into our strategy, we may
experience delays in our growth or may not be able to expand and grow our
business.

If our franchisees cannot develop or finance new restaurants, build them on
suitable sites or open them on schedule, our growth and success may be impeded.

      Our growth depends in part upon our ability to establish a successful and
effective franchise program and to attract qualified franchisees. If our
franchisees are unable to locate suitable sites for new restaurants, negotiate
acceptable lease or purchase terms, obtain the necessary financial or management
resources, meet construction schedules or obtain the necessary permits and
government approvals, our growth plans may be negatively affected. We cannot
assure you that any of the restaurants our franchisees open will be profitable.

Additional foodservice strategic alliances may not be successful and may
materially adversely affect our business and results of operations.

      We may decide to enter into additional alliances with third parties to
develop foodservice strategic alliances in select markets or through select
channels. Identifying strategic partners, negotiating agreements and building
such alliances may divert management's attention away from our existing
businesses and growth plans. If we are not successful in forming additional
foodservice strategic alliances, we may experience delays in our growth and may
not be able to expand and grow our business. If we do form additional strategic
alliances, we cannot assure you that the restaurants opened pursuant to these
strategic alliances will be profitable.

Any inability to manage our growth effectively could materially adversely affect
our operating results.

      Failure to manage our growth effectively could harm our business. We have
grown significantly since our inception and intend to grow substantially in the
future both through a franchising strategy and opening new company-owned
restaurants. Our existing restaurant management systems, financial and


                                        3


management controls and information systems may not be adequate to support our
planned expansion. Our ability to manage our growth effectively will require us
to continue to enhance these systems, procedures and controls. We must attract
and retain talented operating personnel to maintain the quality and service
levels at our existing and future restaurants. We may not be able to effectively
manage these or other aspects of our expansion. We cannot assure you that we
will be able to respond on a timely basis to all of the changing demands that
our planned expansion will impose on management and on our existing
infrastructure. If we are unable to manage our growth effectively, our business,
results of operations and financial condition could be materially adversely
impacted.

If we are unable to successfully integrate future acquisitions, our business
could be negatively impacted. Any acquisitions may also be costly.

      We may consider future strategic acquisitions. Acquisitions involve
numerous risks, including difficulties assimilating new operations and products.
In addition, acquisitions may require significant management time and capital
resources. We cannot assure you that we will have access to the capital required
to finance potential acquisitions on satisfactory terms, that any acquisition
would result in long-term benefits to us, or that management would be able to
manage effectively the resulting business. Future acquisitions are likely to
result in the incurrence of additional indebtedness, which could contain
restrictive covenants, or the issuance of additional equity securities, which
could dilute our existing stockholders. We may also pay too much for a concept
that we acquire relative to the actual economic return obtained. If our
integration efforts are unsuccessful, our business and results of operations
could suffer.

                          Risks Related to Our Business

If we are unable to execute our business strategy, we could be materially
adversely affected.

      Our ability to successfully execute our business strategy will depend on a
number of factors, some of which are beyond our control, including, but not
limited to:

            o     our ability to generate positive cash flow from operations;

            o     identification and availability of suitable restaurant sites;

            o     competition for restaurant sites and customers;

            o     negotiation of favorable leases;

            o     management of construction and development costs of new and
                  renovated restaurants;

            o     securing required governmental approvals and permits;

            o     recruitment and retention of qualified operating personnel;

            o     successful operation and execution in new and existing
                  markets;

            o     recruiting, training and retaining qualified corporate and
                  restaurant personnel and management;

            o     identification of under-performing restaurants and our ability
                  to improve or efficiently close under-performing restaurants,
                  including securing favorable lease termination terms;


                                        4


            o     the rate of our internal growth, and our ability to generate
                  increased revenue from existing restaurants;

            o     our ability to incorporate a franchising and area developer
                  model into our strategy;

            o     competition in new and existing markets;

            o     the reliability of our customer and market studies;

            o     consumer trends;

            o     the cost of our principal food products and supply and
                  delivery shortages or interruptions;

            o     weather conditions; and

            o     general regional and national economic conditions.

      Each of these factors could delay or prevent us from successfully
executing our business strategy, which could adversely affect our growth,
revenues and our results of operations.

We have a limited operating history and we may be unable to achieve
profitability.

      There are currently 94 company-owned restaurants, five of which were
opened during the last quarter of fiscal 2004, one of which opened in each of
the second and third quarters of 2005, six of which opened in the fourth quarter
of 2005 and two of which opened in the first quarter of 2006. Accordingly,
limited historical information is available with which to evaluate our business
and prospects. As a result, forecasts of our future revenues, expenses and
operating results may not be as accurate as they would be if we had a longer
history of operations and of combined operations. In fiscal 2005, we incurred
net losses of $13.1 million, and, since we were formed, we have incurred net
losses of approximately $207.4 million through the end of fiscal 2005 primarily
due to funding operating losses, impairment charges, the cost of our merger in
1999, new restaurant opening expenses and lease termination costs. We intend to
continue to expend significant financial and management resources on the
development of additional restaurants, both company-owned and franchised. We
cannot predict whether we will be able to achieve or sustain revenue growth,
profitability or positive cash flow in the future. See "Management's Discussion
and Analysis of Financial Conditions and Results of Operations" and the
financial statements included in the 2005 Annual Report on Form 10-K for
information on the history of our losses.

If internally generated cash flow from our restaurants does not meet our
expectations, our business, results of operations and financial condition could
be materially adversely affected.

      Our cash resources, and therefore our liquidity, are highly dependent upon
the level of internally generated cash from operations and upon future financing
transactions. Although we believe that we have sufficient liquidity to fund our
working capital requirements for the next twelve months, if cash flows from our
existing restaurants or cash flows from new restaurants that we open do not meet
our expectations or are otherwise insufficient to satisfy our cash needs or
expansion plans, we may have to seek additional financing from external sources
to continue funding our operations or reduce or cease our plans to open or
franchise new restaurants. We cannot predict whether such financing will be
available on terms acceptable to us, or at all.

We may need additional capital in the future and it may not be available on
acceptable terms.


                                        5


      Our business may require significant additional capital in the future to,
among other things, fund our operations, increase the number of company-owned or
franchised restaurants, expand the range of services we offer and finance future
acquisitions and investments. There is no assurance that financing will be
available on terms acceptable to us, or at all. Our ability to obtain additional
financing will be subject to a number of factors, including market conditions,
our operating performance and investor sentiment. These factors may make the
timing, amount, terms and conditions of additional financings unattractive to
us. If we are unable to raise additional capital, our business, results of
operations and financial condition could be materially adversely affected.

Our franchisees could take actions that could harm our business.

      Franchisees are independent contractors and are not our employees.
Although we have developed criteria to evaluate and screen prospective
franchisees, we are limited in the amount of control we can exercise over our
licensed franchisees, and the quality of franchised restaurant operations may be
diminished by any number of factors beyond our control. Franchisees may not have
the business acumen or financial resources necessary to successfully operate
restaurants in a manner consistent with our standards and requirements and may
not hire and train qualified managers and other restaurant personnel. Poor
restaurant operations may affect each restaurant's sales. Our image and
reputation, and the image and reputation of other franchisees, may suffer
materially and system-wide sales could significantly decline if our franchisees
do not operate successfully.

We could face liability from our franchisees.

      A franchisee or government agency may bring legal action against us based
on the franchisee/franchisor relationships. Various state and federal laws
govern our relationship with our franchisees and potential sales of our
franchised restaurants. If we fail to comply with these laws, we could be liable
for damages to franchisees and fines or other penalties. Expensive litigation
with our franchisees or government agencies may adversely affect both our
profits and our important relations with our franchisees.

Our financial results are affected by the financial results of our franchisees.

      We receive royalties from our franchisees. Our financial results are
therefore somewhat contingent upon the operational and financial success of our
franchisees, including implementation of our strategic plans, as well as their
ability to secure adequate financing. If sales trends or economic conditions
worsen for our franchisees, their financial health may worsen and our collection
rates may decline. Additionally, refusal on the part of franchisees to renew
their franchise agreements may result in decreased royalties. Entering into
restructured franchise agreements may result in reduced franchise royalty rates
in the future.

Our restaurants are currently concentrated in the Northeastern and Mid-Atlantic
regions of the United States, particularly in the New York City area.
Accordingly, we are highly vulnerable to negative occurrences in these regions.

      We currently operate 59 company-owned restaurants in Northeastern and
Mid-Atlantic states, of which 16 are located in the New York City area, the
majority of which are located in New York central business districts. As a
result, we are particularly susceptible to adverse trends and economic
conditions in these areas. In addition, given our geographic concentration,
negative publicity regarding any of our restaurants could have a material
adverse effect on our business and operations, as could other regional
occurrences impacting the local economies in these markets.


                                        6


You should not rely on past increases in our average unit volumes as an
indication of our future results of operations because they may fluctuate
significantly.

      A number of factors have historically affected, and will continue to
affect, our average unit sales, including, among other factors:

            o     our ability to execute our business and growth strategy
                  effectively;

            o     introduction of new menu items;

            o     sales performance by our new and existing restaurants;

            o     competition;

            o     general regional and national economic conditions;

            o     weather conditions; and

            o     consumer trends.

      It is not reasonable to expect our average unit volumes to increase at
rates achieved over the past several years. Changes in our average unit volumes
could cause the price of our common stock to fluctuate substantially.

Seasonality, inclement weather and other variable factors may adversely affect
our sales and results of operations and could cause our quarterly results to
fluctuate and fall below expectations of securities analysts and investors,
resulting in a decline in our stock price.

      Our business is subject to significant seasonal fluctuations and weather
influences on consumer spending and dining out patterns. Inclement weather may
result in reduced frequency of dining at our restaurants. Customer counts (and
consequently revenues) are generally highest in spring and summer months and
lowest during the winter months because of the high proportion of our
restaurants located in the Northeast where inclement weather affects customer
visits. As a result, our quarterly and yearly results have varied in the past,
and we believe that our quarterly operating results will vary in the future.
Other factors such as unanticipated increases in labor, commodity, energy,
insurance or other operating costs may also cause our quarterly results to
fluctuate. For this reason, you should not rely upon our quarterly operating
results as indications of future performance.

Our operations depend on governmental licenses and we may face liability under
"dram shop" statutes.

      We are subject to extensive federal, state and local government
regulations, including regulations relating to alcoholic beverage control, the
preparation and sale of food, public health and safety, sanitation, building,
zoning and fire codes. Our business depends on obtaining and maintaining
required food service and/or liquor licenses for each of our restaurants. If we
fail to obtain or maintain all necessary licenses, we may be forced to delay or
cancel new restaurant openings and close or reduce operations at existing
locations. In addition, our sale of alcoholic beverages subjects us to "dram
shop" statutes in some states. These statutes allow an injured person to recover
damages from an establishment that served alcoholic beverages to an intoxicated
person. Although we take significant precautions to ensure that all employees
are trained in the responsible service of alcohol and maintain insurance
policies in accordance with all state regulations regarding the sale of
alcoholic beverages, the misuse of alcoholic


                                        7


beverages by customers may create considerable risks for us. If we are the
subject of a judgment substantially in excess of our insurance coverage, or if
we fail to maintain our insurance coverage, our business, financial condition,
operating results or cash flows could be materially and adversely affected. See
"Business -- Government Regulation" in the 2005 Annual Report on Form 10-K for a
discussion of the regulations with which we must comply.

Our failure or inability to enforce our trademarks or other proprietary rights
could adversely affect our competitive position or the value of our brand.

      We own certain common law trademark rights and a number of federal and
international trademark and service mark registrations, and proprietary rights
to certain of our core menu offerings. We believe that our trademarks and other
proprietary rights are important to our success and our competitive position.
We, therefore, devote appropriate resources to the protection of our trademarks
and proprietary rights. The protective actions that we take, however, may not be
enough to prevent unauthorized usage or imitation by others, which might cause
us to incur significant litigation costs and could harm our image or our brand
or competitive position.

      We also cannot assure you that third parties will not claim that our
trademarks or offerings infringe the proprietary rights of third parties. Any
such claim, whether or not it has merit, could be time-consuming, result in
costly litigation, cause product delays or require us to enter into royalty or
licensing agreements. As a result, any such claim could have a material adverse
effect on our business, results of operations and financial condition.

We hold significant amounts of illiquid assets and may have to dispose of them
on unfavorable terms.

      A certain portion of our assets, such as leasehold improvements and
equipment, are illiquid. These assets cannot be converted into cash quickly and
easily. We may be compelled to dispose of these illiquid assets on unfavorable
terms, which could have an adverse effect on our business.

We may face litigation that could have a material adverse effect on our
business, financial condition and results of operations.

      From time to time, we are a defendant in litigation arising in the
ordinary course of our business. Our customers may file complaints or lawsuits
against us alleging that we are responsible for an illness or injury they
suffered at or after a visit to a Cosi restaurant, or alleging that there was a
problem with food quality or operations at a Cosi restaurant. We may also be
subject to a variety of other claims arising in the ordinary course of our
business, including personal injury claims, contract claims, claims from
franchisees and claims alleging violations of federal and state law regarding
workplace and employment matters, discrimination and similar matters. We could
also become subject to class action lawsuits related to these matters in the
future. To date, none of such litigation, some of which is covered by insurance,
has had a material adverse effect on our consolidated financial position,
results of operations or cash flows.

      Regardless of whether any future claims against us are valid or whether we
are found to be liable, claims may be expensive to defend and may divert our
management's attention away from our operations and hurt our performance. The
outcome of litigation, particularly class action lawsuits and regulatory
actions, is difficult to assess or quantify. Plaintiffs in these types of
lawsuits may seek recovery of very large or indeterminate amounts, and the
magnitude of the potential loss relating to such lawsuits may remain unknown for
substantial periods of time. A judgment significantly in excess of our insurance
coverage for any claims could materially adversely affect our financial
condition or results of operations. There may also be adverse publicity
associated with litigation that could decrease customer acceptance of


                                        8


our services or those of our franchisees, regardless of whether the allegations
are valid or whether we are ultimately found liable. As a result, litigation may
adversely affect our business, financial condition and results of operations.
Moreover, complaints, litigation or adverse publicity experienced by one or more
of our franchisees could also hurt our business as a whole.

We have a new management team that does not have proven success with the
Company.

      Some members of our management team have been in place for only a
relatively short period of time. They do not have previous experience with us,
and we cannot assure you that they will fully integrate themselves into our
business or that they will effectively manage our business affairs. Our failure
to assimilate the new members of management, the failure of the new members of
management to perform effectively, or the loss of any of the new members of
management could have a material adverse effect on our business, financial
condition and results of operations.

If we are unable to protect our customers' credit card data, we could be exposed
to data loss, litigation and liability, and our reputation could be
significantly harmed.

      In connection with credit card sales, we transmit confidential credit card
information securely over public networks and store it in our data warehouse.
Third parties may have the technology or know-how to breach the security of this
customer information, and our security measures may not effectively prohibit
others from obtaining improper access to this information. If a person is able
to circumvent our security measures, he or she could destroy or steal valuable
information or disrupt our operations. Any security breach could expose us to
risks of data loss, litigation and liability and could seriously disrupt our
operations and any resulting negative publicity could significantly harm our
reputation.

                   Risks Relating to the Food Service Industry

Our business is affected by changes in consumer preferences.

      Our success depends, in part, upon the popularity of our food products,
our ability to develop new menu items that appeal to consumers and what we
believe is an emerging trend in consumer preferences toward premium convenience
restaurants. We depend on consumers who prefer made-to-order food in a
sophisticated environment and are willing to pay a premium price for our
products. We also depend on trends toward consumers eating away from home more
often. Shifts in consumer preferences away from our restaurants or cuisine, our
inability to develop new menu items that appeal to consumers or changes in our
menu that eliminate items popular with some consumers could harm our business
and future profitability.

General economic conditions and the effects of the war on terrorism may cause a
decline in discretionary consumer spending, which would negatively affect our
business.

      Our success depends to a significant extent on discretionary consumer
spending, which is influenced by general economic and political conditions and
the availability of discretionary income. Accordingly, we may experience
declines in sales during economic downturns or during periods of uncertainty
like that which followed the September 11, 2001 terrorist attacks on the United
States. In addition, economic uncertainty due to military action overseas, such
as in Iraq and post-war military, diplomatic or financial responses, may lead to
further declines in sales. Any decline in consumer spending or economic
conditions could reduce customer traffic or impose practical limits on pricing,
either of which could have a material adverse effect on our sales, results of
operations, business and financial condition.


                                        9


Our success depends on our ability to compete with many food service businesses.

      The restaurant industry is intensely competitive and we compete with many
well-established food service companies on the basis of taste, quality and price
of product offered, customer service, atmosphere, location and overall guest
experience. We compete with other sandwich retailers, specialty coffee
retailers, bagel shops, fast-food restaurants, delicatessens, cafes, bars,
take-out food service companies, supermarkets and convenience stores. Our
competitors change with each daypart (breakfast, lunch and dinner), ranging from
coffee bars and bakery cafes to casual dining chains. Aggressive pricing by our
competitors or the entrance of new competitors into our markets could reduce our
sales and profit margins.

      Many of our competitors or potential competitors have substantially
greater financial and other resources than we do, which may allow them to react
to changes in pricing, marketing and the quick service restaurant industry
better than we can. As competitors expand their operations, we expect
competition to intensify. We also compete with other employers in our markets
for hourly workers and may be subject to higher labor costs.

Fluctuations in coffee prices could adversely affect our operating results.

      The price of coffee, one of our main products, can be highly volatile.
Although most coffee trades on the commodity markets, coffee of the quality we
seek tends to trade on a negotiated basis at a substantial premium above
commodity coffee pricing, depending on supply and demand at the time of the
purchase. Supplies and prices of green coffee can be affected by a variety of
factors, such as weather, politics and economics in the producing countries. An
increase in pricing of specialty coffees could have a significant adverse effect
on our profitability. To mitigate the risks of increasing coffee prices and to
allow greater predictability in coffee pricing, we typically enter into
short-term purchasing arrangements for a portion of our green coffee
requirements. We cannot assure you that these activities will be successful or
that they will not result in our paying substantially more for our coffee supply
than we would have been required to pay absent such activities. We purchase
coffee through a single supplier under an agreement that expires in June 2010.

Changes in food and supply costs could adversely affect our results of
operations.

      Our profitability depends in part on our ability to anticipate and react
to changes in food and supply costs. We rely on a single primary distributor of
our food and paper goods. Although we believe that alternative distribution
sources are available, any increase in distribution prices or failure by our
distributor to perform could adversely affect our operating results. In
addition, we are susceptible to increases in food costs as a result of factors
beyond our control, such as weather conditions and government regulations.
Failure to anticipate and adjust our purchasing practices to these changes could
negatively impact our business.

The food service industry is affected by litigation and publicity concerning
food quality, health and other issues, which can cause customers to avoid our
products and result in liabilities.

      Food service businesses can be adversely affected by litigation and
complaints from customers or government authorities resulting from food quality,
illness, injury or other health concerns or operating issues stemming from one
restaurant or a limited number of restaurants. Adverse publicity about these
allegations may negatively affect us, regardless of whether the allegations are
true, by discouraging customers from buying our products. We could also incur
significant liabilities if a lawsuit or claim results in a decision against us
or if we incur litigation costs, regardless of the result.


                                       10


Our business could be adversely affected by increased labor costs or labor
shortages.

      Labor is a primary component in the cost of operating our business. We
devote significant resources to recruiting and training our managers and
employees. Increased labor costs, due to competition, increased minimum wage or
employee benefits costs or otherwise, would adversely impact our operating
expenses. In addition, our success depends on our ability to attract, motivate
and retain qualified employees, including restaurant managers and staff, to keep
pace with our needs. If we are unable to do so, our results of operations may be
adversely affected.

              CAUTIONARY NOTE REGARDING FORWARD LOOKING STATEMENTS

      We caution that any forward-looking statements (as such term is defined in
the Private Securities Litigation Reform Act of 1995) contained or incorporated
by reference in this Form S-8 or made by our management involve risks and
uncertainties and are subject to change based on various important factors, many
of which may be beyond our control. Accordingly, our future performance and
financial results may differ materially from those expressed or implied in any
such forward-looking statements. For these statements, we claim the protection
of the safe harbor for forward-looking statements contained in the Private
Securities Litigation Reform Act of 1995. Any such forward-looking statements
are subject to risks and uncertainties, including those described in this
registration statement. If any of these risks or uncertainties actually occurs,
our business, financial condition or operating results could be materially and
adversely affected, and the trading price of our common stock could decline. We
do not undertake to publicly update or revise our forward-looking statements
even if experience our future changes make it clear that any projected results
expressed or implied therein will not be realized.

            o     the cost of our principal food products and supply and
                  delivery shortages or interruptions;

            o     our ability to generate positive cash flow from existing and
                  new restaurants;

            o     fluctuations in our quarterly results due to seasonality;

            o     increased government regulation and our ability to secure
                  required governmental approvals and permits;

            o     our ability to create customer awareness of our restaurants in
                  new markets;


                                       11


            o     the reliability of our customer and market studies;

            o     our ability to recruit, train and retain qualified corporate
                  and restaurant personnel and management;

            o     market saturation due to new restaurant openings;

            o     inadequate protection of our intellectual property;

            o     adverse weather conditions which impact customer traffic at
                  our restaurants; and

            o     adverse economic conditions.

commissions or discounts received by any such broker or dealer may be deemed to
be underwriting compensation under the Securities Act. In addition, any such

Item 4. Description of Securities.

      Not applicable.

Item 5. Interests of Named Experts and Counsel.

      None.

Item 6. Indemnification of Directors and Officers.

      Section 145 of the Delaware General Corporation Law permits
indemnification of officers, directors, and other corporate agents under certain

indemnify its directors and officers, and anyone who is or was serving at the
Company's request as a director, officer, employee, fiduciary, or agent of
another corporation or of a partnership, joint venture, trust or other
enterprise, to the fullest extent permitted under Delaware law. These
indemnification provisions may be sufficiently broad to permit indemnification
of the Company's executive officers and directors for liabilities (including
reimbursement of expenses incurred) arising under the Securities Act.

      The Company maintains directors' and officers' liability insurance against
any actual or alleged error, misstatement, misleading statement, act, omission,
neglect or breach of duty by any director or officer, excluding certain matters
including fraudulent, dishonest or criminal acts or self dealing.

                                      II-1


Securities Act. Such restricted securities were issued pursuant to the Cosi,
Inc. 2005 Omnibus Long-Term Incentive Plan.

Item 9. Undertakings.

      The undersigned registrant hereby undertakes:

      (a)(1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

            (i) to include any prospectus required by Section 10(a)(3) of the
      Securities Act;

            (ii) to reflect in the prospectus any facts or events arising after
      the effective date of this Registration Statement (or the most recent
      post-effective amendment thereof) which, individually or in the aggregate,
      represent a fundamental change in the information set forth in this
      Registration Statement. Notwithstanding the foregoing, any increase or
      decrease in the volume of securities offered (if the total dollar value of
      securities offered would not exceed that which was registered) and any
      deviation from the low or high end of the estimated maximum offering range
      may be reflected in the form of prospectus filed with the SEC pursuant to
      Rule 424(b) if, in the aggregate, the changes in volume and price
      represent no more than 20 percent change in the maximum aggregate offering
      price set forth in the "Calculation of Registration Fee" table in the
      effective Registration Statement;


                                      II-2


            (iii) to include any material information with respect to the plan
      of distribution not previously disclosed in this Registration Statement or
      any material change to such information in this Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the SEC
by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act
that are incorporated by reference in the Registration Statement.

            (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time will be deemed to be the initial bona
fide offering thereof.

            (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

      (b) That, for purposes of determining any liability under the Securities
Act, each filing of the registrant's annual report pursuant to Section 13(a) or
15(d) of the Exchange Act that is incorporated by reference in this Registration
Statement shall be deemed to be a new registration statement relating to the
securities offered therein and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

      (c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the provisions referred to in this Registration
Statement, or otherwise, the registrant has been advised that in the opinion of
the SEC such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.


                                      II-3


                                   SIGNATURES

      Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this Registration
