1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Basis of Presentation

            The unaudited condensed financial statements of Diedrich Coffee,
      Inc. (the "Company") have been prepared in accordance with generally
      accepted accounting principles for interim financial information. In the
      opinion of management, all adjustments (consisting of normal, recurring
      adjustments and accruals) considered necessary for a fair presentation of
      the Company's financial position at April 30, 1997 and the results of
      operations and cash flows for the thirteen weeks ended April 30, 1997 and
      May 1, 1996 have been included. Results for the interim periods are not
      necessarily indicative of the results for an entire year. This information
      should be read in conjunction with the financial statements and the notes
      thereto included in the Company's latest Form 10-K.

            At April 30, 1997, the Company operated 44 coffeehouses in Southern
      California, Denver and Houston. The Company also operates roasting
      facilities in Irvine, California and Denver, Colorado. At May 1, 1996, the
      Company operated 32 coffeehouses including 18 locations acquired in
      February 1996 of which 16 were in Denver and two were in Houston. At May
      1, 1996, none of the acquired locations had been converted to the Diedrich
      Coffee format.

      Net Income (Loss) per Common Share

            The calculation of net income (loss) per share was determined by
      dividing the net income (loss) by the weighted average common and common
      equivalent shares outstanding when dilutive. In accordance with Securities
      and Exchange Commission Staff Accounting Bulletin No. 83, shares issued
      and share options granted within one year of the initial public offering
      ("IPO") have been included in the calculation of common share equivalents,
      using the treasury stock method to determine the dilutive effect of the
      issuances, as if they were outstanding for all periods presented even if
      they were antidilutive. The calculation of common share equivalents
      assumes that the proceeds of common shares and share options issued within
      one year of the IPO were used to repurchase common shares at the IPO price
      of $9.50 per share. Primary earnings per share approximates fully diluted
      earnings per share for all periods presented.

            In February 1997, the Financial Accounting Standards Board issued
      Statement of Accounting Standards ("SFAS") No. 128, "Earnings Per Share."
      SFAS 128 specifies new standards designed to improve the earnings per
      share ("EPS") information provided in financial statements by simplifying
      the existing computational guidelines, revising the disclosure
      requirements and increasing the comparability of EPS data on an
      international basis. SFAS No. 128 is effective for financial statements
      issued for periods ending after December 15, 1997, including interim
      periods. The Company does not believe the implementation of SFAS No. 128
      will have a material effect on net income (loss) per share.

3.    DEBT

            On July 19, 1996, the Company entered into a bank revolving line of
      credit agreement which provided for borrowings up to $4,100,000 with
      interest payable at the bank's reference rate plus .25% or, at the
      Company's option, certain other international interest rates established
      by the bank plus 2.25%. Upon consummation of the Company's Initial Public
      Offering in September 1996, the maturity date was extended to October 1,
      1997 and the maximum borrowings were increased to $6 million. On April 21,
      1997, the bank revolving line of credit was canceled.

            In March 1997, the Company received a commitment for a $1 million
      line of credit on arms-length terms from a significant stockholder of the
      Company. As of April 30, 1997, the Company had no outstanding borrowings
      under this commitment. The specific terms of this line of credit have not
      yet been finalized.

4.    RESTRUCTURING CHARGE

            On March 12, 1997, the Company announced that it was reviewing the
      performance of all of the Company's coffeehouses to determine which units
      were not meeting management's long-term operational expectations. At that
      time, five coffeehouses had been identified on a preliminary basis for
      possible closure in the first quarter of fiscal 1998. Subsequently, as
      announced by the Company on April 29, 1997, the board of directors has
      authorized the closure of seven additional coffeehouses during fiscal
      1998. In connection with the store closures, the Company recorded an
      impairment provision and a restructuring charge totaling approximately
      $4.6 million in the first quarter of fiscal 1998. The store closures,
      which were undertaken to streamline operations and improve profitability,
      began in late March 1997 and are expected to be substantially completed
      during fiscal 1998.

                  ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

GENERAL

      The first retail store operating under the name Diedrich Coffee commenced
operations in 1972. At the conclusion of fiscal 1997, there were forty seven
coffeehouses in operation, located in California, Colorado and Texas. As of
April 30, 1997, the Company operated a total of forty-four coffeehouses as a
result of the closure of three of the twelve locations designated for closure
under the restructuring plan as discussed below.

       Diedrich Coffee sells high quality coffee beverages made with its own
freshly roasted coffee. In addition to brewed coffee, the Company offers a broad
range of Italian-style beverages such as espresso, cappuccino, caffe latte, cafe
mocha and espresso machiato. To complement beverage sales, the Company sells
light food items and whole bean coffee through its coffeehouses.

      On March 12, 1997, the Company announced that it was reviewing the
performance of all of the Company's coffeehouses to determine which units were
not meeting management's long-term operational expectations. At that time, five
coffeehouses had been identified on a preliminary basis for possible closure in
the first quarter of fiscal 1998. Subsequently, as announced by the Company on
April 29, 1997, the Board of Directors has authorized the closure of seven 
additional coffeehouses during fiscal 1998. In connection with the store
closures, the Company recorded an impairment provision and a restructuring
charge totaling $4.6 million in the first quarter of fiscal 1998. The store
closures, which were undertaken to streamline operations and improve
profitability, began in late March 1997 and are expected to be substantially
completed during fiscal 1998.

      On March 12, 1997, the Company also announced the resignation of Steven A.
Lupinacci as its President, Chief Executive Officer, Chief Financial Officer 
and Director and the appointment of Lawrence Goelman, one of the Company's board
members, to serve as interim President and Chief Executive Officer. On April 25,
1997, the Company's Board of Directors approved the appointment of Kerry W. Coin
as President and Chief Operating Officer and the appointment of John B. Bayley
as Acting Vice President, Finance and Controller.

      In addition to historical information, management's discussion and
analysis includes certain forward-looking statements, including those related to
the Company's growth and strategies, that involve risks and uncertainties. The
Company's actual results and financial position could differ materially from
those anticipated in the forward-looking statements as a result of a number of
factors, including but not limited to, the price and availability of coffee and
other raw materials, successful execution of the Company's expansion plans, the
impact of competition, the availability of additional financing and other risks
and uncertainties as described in detail under "Certain Factors and Trends
Affecting Diedrich Coffee and Its Business" in the Company's annual report on
Form 10-K for the fiscal year ended January 29, 1997 and in reports filed by the
Company with the Securities and Exchange Commission.

RESULTS OF OPERATIONS

Thirteen Weeks Ended April 30, 1997 Compared with the Thirteen Weeks
Ended May 1, 1996

      Net sales. Net sales for the thirteen weeks ended April 30, 1997,
increased 37.3% to $5,868,000 from $4,275,000 for the thirteen weeks ended May
1, 1996. During this most recent quarter, the Company derived 91.8% of net sales
from its retail coffeehouse operations. The Company's wholesale and mail order
sales account for the remainder of net sales. Net retail sales for the thirteen
weeks ended April 30, 1997


                                        8
<PAGE>   9
increased 38.0% to $5,385,000 from $3,902,000 in the thirteen weeks ended May 1,
1996 primarily due to the opening of new coffeehouses.

      Wholesale and mail order sales combined increased 29.6% to $483,000 in the
thirteen weeks ended April 30, 1997 from $373,000 in the thirteen weeks ended
May 1, 1996. The increase was due to a more active sales effort and continued
favorable customer response from new and existing wholesale accounts. A moderate
price increase on roasted whole bean coffee was implemented during the quarter
in response to industry wide cost pressures resulting from a continuing increase
in the price of green coffee.

      The percentage decrease in comparable store sales comparing net sales for
stores open during the full period in the first quarter in fiscal 1997 to net
sales for the same stores in the first quarter of fiscal 1998 was 5.1%.  Only
12 of the Company's 44 coffeehouses were open for the full period in the first
quarter in fiscal 1997 and are therefore included in the base for comparable
store sales. On average these stores have been open for more than 4.5 years and
had sales of approximately $212,000 per store for the 13 weeks ended April 30,
1997. Management believes that the variation in comparable store sales results
in part from the over-representation of mature, revenue-stable stores in the
computation base. Furthermore, given the small number of stores included in the
base for comparable store sales, management believes that this percentage will
remain volatile until the base contains a more statistically meaningful number
of stores that more accurately reflects the overall composition of the Company.

      Cost of sales and related occupancy costs. Cost of roasted coffee, dairy,
food, paper and bar supplies, accessories and clothing (cost of sales) and rent
(related occupancy costs) for the thirteen weeks ended April 30, 1997 increased
to $3,042,000 from $1,773,000 for the thirteen weeks ended May 1, 1996. As a
percentage of retail net sales, cost of sales and related occupancy costs
increased to 56.5% in the first quarter of fiscal 1998 from 45.4% for the first
quarter of fiscal 1997. This increase was primarily the result of low sales
volume for certain stores acquired during the previous fiscal year which 
resulted in substantially higher rent as a percentage of sales and newly opened
stores with higher initial product costs during the growth period in their early
months of operations.

      Store operating expenses. Store operating expenses increased to $2,380,000
for the thirteen weeks ended April 30, 1997 from $1,735,000 for the thirteen
weeks ended May 1, 1996. As a percentage of retail net sales, store operating
expenses decreased slightly to 44.2% in the first quarter of fiscal 1998 from
44.5% in the prior fiscal year's first quarter.

      Other operating expenses. Other operating expenses (those associated with
wholesale and mail order sales) increased to $64,000 for the first quarter of
fiscal 1998 from $59,000 in the first quarter of fiscal 1997. These expenses, as
a percentage of the net sales from the wholesale division, decreased to 13.3%
from 15.9%. These decreases are a result of an increase in wholesale sales
volume that has exceeded the growth in sales and support infrastructure.

      Depreciation and Amortization. Depreciation and amortization increased to
$447,000 for the thirteen weeks ended April 30, 1997 from $154,000 for the
thirteen weeks ended May 1, 1996. As a percentage of net sales, depreciation and
amortization increased to 7.6% from 3.6% in the prior year, principally due to
the increase in depreciable assets as a result of the Company operating eight
more coffeehouses this quarter than during the first quarter in the prior fiscal
year as well as the addition of the conversion costs for the acquired locations.

      General and administrative expenses. General and administrative expenses
increased to $774,000 for the first quarter of fiscal 1998 from $337,000 for the
first quarter of fiscal 1997. As a percentage of net sales, general and
administrative expenses increased to 13.2% from 7.9 % due to the


                                        9
<PAGE>   10
adding of selected resources and personnel in order to implement the policies
and procedures necessary for the effective control of multi-state operations and
new points of distribution operating at various volume levels.

      Provision for store closings and restructuring costs. In response to
lower than expected profitability in certain of its operations the Company has
commenced a restructuring program which includes store closures, lease
terminations and the write off of fixed assets. The $4.6 million, or $.84 per
share restructuring and impairment charge reflects anticipated expenses related
to the program. The restructuring charge primarily includes lease termination
and other costs associated with store closures as well as a provision for the
impairment of long-lived assets in accordance with Statement of Financial
Accounting Standards No. 121.

      Operating (loss) income. Operating loss for the thirteen weeks ended 
April 30, 1997 was $5,390,000 compared to operating income of $216,000 for the
thirteen weeks ended May 1, 1996. This change was principally the result of the
restructuring provision discussed above as well as increases in cost of sales
and related occupancy, depreciation and amortization, and general and
administrative costs as a percentage of sales.

      Interest expense. Interest expense decreased to $0 for the thirteen weeks
ended April 30, 1997 from $39,000 for the thirteen weeks ended May 1, 1996.

      Net (loss) income. Net loss for the thirteen weeks ended April 30, 1997 
was $5,383,000 compared to net income of $107,000 for the thirteen weeks ended 
May 1, 1996. This change was essentially related to the same factors listed
above with regard to operating (loss) income.


LIQUIDITY AND CAPITAL RESOURCES

      The Company had a working capital deficiency of $1,373,000 as of April 30,
1997 compared to working capital of $1,949,000 as of January 29, 1997. Cash used
by operating activities for the thirteen weeks ended April 30, 1997 totaled
$1,304,000. In addition, the Company recorded an impairment provision of
$2,043,000 as of April 30 as a portion of the restructuring and impairment
charges discussed above.

      In July 1996, the Company entered into a revolving credit agreement with
Bank of America which permitted the Company to borrow up to $6 million upon
completion of the Company's initial public offering. The Company's credit
agreement in connection with this line of credit contained various covenants
which, among other things, required the delivery of regular financial
information, the maintenance of positive net income and the maintenance of
unencumbered liquid assets. In addition, the credit agreement imposed certain
restrictions on the Company, including restrictions with respect to the
incurrence of additional indebtedness, the payment of dividends and the ability
to make acquisitions. On March 31, 1997, the Company was notified that it was in
breach of its covenant to maintain the required level of net income pursuant to
the credit agreement. The Company had no outstanding borrowings under this line
of credit and the fact that the credit agreement continued to impose numerous
restrictions upon the Company, caused it to reconsider the agreement and the
Company determined that it was in its best interest to terminate this line of
credit on April 21, 1997.

      In March 1997, the Company received a commitment for a $1 million line of
credit on arms-length terms from a significant stockholder of the Company. At
April 30, 1997 the Company had no outstanding borrowings under this commitment.
The specific terms of this line of credit have not been finalized.


                                       10
<PAGE>   11
      The Company believes that cash from operations and the stockholder line of
credit commitment will be sufficient to satisfy the Company's working capital
needs for the remainder of the fiscal year. However, the Company anticipates it
will need to seek additional financing or equity to fund additional
acquisitions, capital expenditures for new retail locations and cash
expenditures associated with the Company's restructuring plan. The Company is
currently in negotiations with certain stockholders as well as third parties for
both secured and unsecured lines of credit that can be used for these purposes.
The Company plans to have one or more of these lines in place prior to the end
of its second fiscal quarter which ends July 30, 1997.

COFFEE PRICES AND AVAILABILITY

      In the later weeks of the fiscal quarter the coffee commodities market
experienced a substantial rise in the base price of green coffee. The Company
believes that it has adequate sources of supply of high quality arabica coffee
to meet its projected needs for the foreseeable future. The average price for
coffee acquired during the thirteen weeks ended April 30, 1997 did not increase
materially in comparison with the prior year as these cost increases occurred
late in the quarter. While the Company seeks to carefully anticipate its coffee
needs, there can be no assurance that the prices it will have to pay for the
highest quality coffee available will remain stable in the future.


SEASONALITY AND QUARTERLY RESULTS

      The Company's business is subject to seasonal fluctuations as well as
general economic trends that affect retailers in general. Historically, the
Company's net sales have not been realized ratably in each quarter, with net
sales being the highest during the last fiscal quarter which includes the
December holiday season. Quarterly results are affected by the timing of the
opening of new stores which may not occur as anticipated due to factors outside
the Company's control. As a result of the combination of the seasonality of the
retail operations, the financial results for any individual quarter may not be
indicative of the results that may be achieved for a full fiscal year.
