              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 8, 2000
                                   (UNAUDITED)



1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Basis of Presentation

         The unaudited condensed consolidated financial statements of Diedrich
Coffee, Inc. (the "Company") and its subsidiaries have been prepared in
accordance with generally accepted accounting principles, the instructions to
Form 10-Q and Article 10 of Regulation S-X. Information relating to the periods
ending prior to July 7, 1999 included in this report relates to the historical
operations of Diedrich Coffee, Inc. and, except as otherwise indicated, does not
reflect the operations of Coffee People, Inc. ("Coffee People"), which the
Company acquired on July 7, 1999. These statements should be read in conjunction
with the financial statements and the notes thereto included in the Company's
Annual Report on Form 10-K for the year ended January 27, 1999 and the Company's
transition report on Form 10-Q for the transition period January 28, 1999 to
June 30, 1999.

         In the opinion of management, all adjustments (consisting of normal,
recurring adjustments and accruals) considered necessary for a fair presentation
have been included. Operating results for interim periods are not necessarily
indicative of the results expected for a full year.

         Change in Fiscal Year

         In an effort to align its fiscal year with that of Coffee People, the
Company changed its year-end from a fiscal year ending on the Wednesday nearest
January 31 to a fiscal year ending on the Wednesday nearest June 30.
Accordingly, the condensed statements of operations and cash flows for the
twelve and thirty-six weeks ended March 8, 2000 are not necessarily comparable
to the accompanying thirteen and thirty-nine weeks ended April 28, 1999.

2.       ACQUISITION OF COFFEE PEOPLE, INC.

         On July 7, 1999, the Company acquired Coffee People pursuant to an
Agreement and Plan of Merger. The acquisition was affected through the merger of
CP Acquisition Corp., an indirect wholly owned subsidiary of the Company, with
and into Coffee People. As a result of the acquisition, each share of Coffee
People common stock was converted into the right to receive $2.11 in cash and
0.14 share of the Company's common stock. At the time of the acquisition, Coffee
People owned 67 retail stores and franchised 253 retail stores in 36 states and
7 foreign countries under the names Gloria Jean's, Coffee People and Coffee
Plantation.

         The Company, in recording the fair value of assets acquired and
liabilities assumed, has made certain estimates. These estimates consist
primarily of (i) recording property and equipment at estimated fair value and
(ii) providing for contractual lease obligations on negative operating cash
flows on certain underperforming stores. The acquisition has been accounted for
as a purchase and the resulting estimated costs in excess of net assets acquired
in the amount of $30,658,394 are being amortized using the straight-line method
over a 40 year period. The allocation of purchase price to the fair value of
assets acquired and liabilities assumed is dependent upon certain valuations and
other studies that have not progressed to a stage where there is sufficient
information to make a definitive allocation. Although the purchase price
allocation is preliminary, management is unaware of any significant changes
necessary to arrive at a final allocation.

         The assets acquired, including the costs in excess of net assets
acquired, and liabilities assumed in the acquisition of Coffee People are
summarized in the following table.

                                                         ============

         In conjunction with the transaction, the Company acquired 31 corporate
owned Gloria Jean's stores, of which 8 will continue to operate as corporate
owned Gloria Jean's stores, 9 have been sold to Gloria Jean's franchisees, 5
have been closed and there are 9 which we intend to close or dispose of by June
28, 2000. Under the provisions of Emerging Issues Task Force 87-11 Allocation of
Purchase Price to Assets to Be Sold, the Company has excluded the operating
results of the 23 stores from the condensed consolidated statement of operations
for the twelve and thirty-six weeks ended March 8, 2000. Additionally, the
Company established a reserve of $1.6 million for the estimated net cash holding
costs of these stores until the estimated date of closure or disposal.

         The total revenues excluded from the Company's condensed consolidated
statement of operations for the twelve and thirty-six weeks ended March 8, 2000
totaled $0.8 million and $2.8 million, respectively, and the related net losses
totaled $68,708 and $346,515, respectively. Such net losses have been charged
against the reserve for the disposal of stores.

         The following table presents selected unaudited pro forma results of
operations for the Company, assuming the Coffee People acquisition had occurred
on July 1, 1998. The unaudited pro forma results of operations do not include
the operating results of the 23 Gloria Jean's Company-owned stores to be closed
or disposed of. The pro forma results of operations are not indicative of the
results of operations of the combined companies that would have occurred had the
acquisition occurred on July 1, 1998, nor are they indicative of future
operating results.

FORWARD LOOKING STATEMENTS

         We make forward-looking statements in this document that are subject to
risks and uncertainties. These forward-looking statements include information
about possible or assumed future results of Diedrich Coffee's financial
condition, operations, plans, objectives and performance. Additionally, when we
use the words "believe," "expect," "anticipate," "estimate" or similar
expressions, we are making forward-looking statements. Many possible events or
factors could affect our future financial results and performance. This could
cause our results or performance to differ materially from those expressed in
our forward-looking statements. You should consider these risks when you review
this document, along with the following possible events or factors:

         o  our growth strategy may not be as successful as we expect if we are
            unable to attract franchise area developers or single store
            franchisees;

         o  our growth strategy may not be as successful if franchisees are
            unable to secure attractive real estate;

         o  we may encounter difficulties and incur additional expenses as we
            integrate Diedrich Coffee's and Coffee People's business, brands or
            operating systems or retaining key personnel;

         o  competition within the retail specialty coffee market may intensify;

         o  inclement weather or adverse political changes in the countries
            where we source our green coffee may significantly increase our
            coffee costs; and

         o  adverse changes may occur in the securities or financial markets.


         Foreseeable risks and uncertainties are described elsewhere in this
report and in detail under "Risk Factors and Trends Affecting Diedrich Coffee
and Its Business" in our Annual Report on Form 10-K for the fiscal year ended
April 28, 1999 and in reports that we file with the Securities and Exchange
Commission.

GENERAL

         The first retail store operating under the name of Diedrich Coffee
commenced operations in 1972. Following our acquisition of Coffee People on July
7, 1999, we became the second largest specialty coffee retailer in the United
States with annual systemwide sales of more than $150 million. We currently own,
operate or franchise 362 retail locations in 38 states and 9 foreign countries.
Our primary brands are Diedrich Coffee coffeehouses and Gloria Jean's, the
nation's largest chain of mall coffee stores. We sell specialty brewed coffee
and espresso-based beverages such as cappuccinos, lattes, mochas and espressos
and various blended drinks through these company-owned and franchised retail
locations. To complement beverage sales, we also sell light food items, whole
bean coffee and accessories at our retail locations. In addition, we have a
strong wholesale division that markets its products directly to independent and
chain food service establishments, as well as to businesses for office coffee
systems through brokers and sales representatives. We also sell our products
directly to customers through mail orders and our website.

         Coffee People Acquisition. On July 7, 1999, we completed our
acquisition of Coffee People pursuant to an Agreement and Plan of Merger, dated
as of March 16, 1999. The acquisition was effected by way of a merger of CP
Acquisition Corp., an indirect wholly owned subsidiary of Diedrich Coffee, with
and into Coffee People. As a result of the merger, each share of Coffee People
common stock was converted into the right to receive $2.11 in cash and 0.14
share of our common stock. The cash payment to Coffee People stockholders was
financed by a portion of the net proceeds of a public equity offering of
4,930,000 shares of our common stock at a price of $6.00 per share.

         On July 7, 1999, we entered into a credit agreement with BankBoston,
N.A. that is secured by pledges of all of our assets and our subsidiaries' stock
and provides for a $12 million term loan and a $3 million revolving credit
facility, payable in quarterly installments with final maturity in July 2004. We
used the proceeds of the term loan to repay existing indebtedness and to pay
expenses related to the acquisition of Coffee People and our public equity
offering. When we draw down the revolving credit facility, we intend to use the
proceeds to finance additional and remodel existing company-owned retail
locations and for general corporate purposes. Amounts outstanding under the
credit agreement bear interest, at our option, at BankBoston's base rate plus
1.25% or an adjusted Eurodollar rate plus 3.0%

         Franchise Area Development Agreements. Management's franchise area
development goal is to enter into franchise area development agreements covering
most major U. S. markets. Presently, we have nine franchise area development
agreements calling for the development of up to 351 Diedrich coffeehouses, as
well as carts and kiosks, over the next 5 to 7 years. In addition, two of these
agreements contain options to develop an additional 143 coffeehouses.

         Since July 1, 1999, the start of our current fiscal year, we have
entered into four area development agreements and terminated one area
development agreement. The terminated area development agreement covered the
states of Kentucky and Tennessee. On August 23, 1999, we announced a franchise
area development agreement which calls for the development of 50 coffeehouses in
Wyoming, Montana and Colorado. On October 19, 1999 we announced a franchise area
development agreement which provides for the development of 50 coffeehouses in
various counties in Southern California including Kern, San Luis Obispo, Ventura
and Santa Barbara as well as portions of Los Angeles, San Bernardino, Riverside
and Orange. On January 20, 2000, we announced a franchise area development
agreement which calls for the development of 50 coffeehouses in Connecticut,
Western Massachusetts and upstate New York. On March 20, 2000, we announced a
franchise area development agreement which call for the development of 17
coffeehouses in Nevada. We are currently in various stages of discussion and
negotiations with several additional potential area developers.

         On November 2, 1999, we announced that our Gloria Jean's Coffees
Division signed a franchise area development agreement which provides for the
development of 30 Gloria Jean's brand stores in South East Asian countries
including Malaysia, Singapore and Brunei.

         Year 2000. The year 2000 problem was the result of computer programs
being written using two digits rather than four to define the applicable year.
Miscalculations or system failures could have occurred to any of our programs on
or after January 1, 2000 that had time-sensitive software if they had recognized
dates using "00" as the year 1900 rather than the year 2000. Based on our review
of our business since January 1, 2000, we have not experienced any material
effects of the year 2000 problem. Although we have not been informed of any
material risks associated with the year 2000 problem from third parties, there
can be no assurance that they may not impact our business in the future. We are
continuously monitoring our business applications and have constant
communication with significant suppliers and key business partners so that we
may resolve any year 2000 problems that arise in the future.

         Seasonality and Quarterly Results. Our business is subject to seasonal
fluctuations as well as economic trends that affect retailers in general.
Historically, our net revenues have not been realized proportionately in each
quarter, with net revenues being the highest during the December holiday season.
Hot weather tends to reduce revenues. Quarterly results are affected by the
timing of the opening of new stores, which may not occur as anticipated due to
events outside our control. As a result of these factors, and of the other
contingencies and risk factors described elsewhere in this report, our Annual
Report on Form 10-K and our Transition Report on Form 10-Q, the financial
results for any individual quarter may not be indicative of the results that may
be achieved in a full fiscal year.

RESULTS OF OPERATIONS

         Coffee People Acquisition. On July 7, 1999, we acquired Coffee People
in a transaction that was accounted for using the purchase method of accounting;
and accordingly, the assets acquired and liabilities assumed were recorded as of
their fair values on that date. The results of operations for the periods ended
March 8, 2000 and April 28, 1999 differ significantly because of the acquisition
of Coffee People in July 1999. The resulting estimated costs in excess of net
assets of the business acquired in the amount of $30,658,394 are being amortized
using the straight-line method over a 40 year period.

         Change in Fiscal Year. In an effort to align our fiscal year with that
of Coffee People which we acquired on July 7, 1999, we changed our year end from
a fiscal year ending on the Wednesday nearest January 31 to a fiscal year ending
on the Wednesday nearest June 30. Accordingly, the condensed consolidated
financial statements for the twelve and thirty-six weeks ended March 8, 2000 are
not necessarily comparable to the accompanying condensed consolidated financial
statements for the thirteen and thirty-nine weeks ended April 28, 1999.

Twelve and Thirty-Six Weeks Ended March 8, 2000 Compared with the Thirteen and
Thirty-Nine Weeks Ended April 28, 1999

         Total revenues. Total revenues for the twelve weeks ended March 8, 2000
increased 175% to $16,745,000 from $6,098,000 for the thirteen weeks ended April
28, 1999. Total revenues for the thirty-six weeks ended March 8, 2000 increased
184% to $52,151,000 from $18,361,000 for the thirty-nine weeks ended April 28,
1999. These increases were principally due to the acquisition of Coffee People
and also due to an increase in comparable store sales for the Diedrich Coffee
coffeehouses and the Coffee People coffeehouses. During this most recent
quarter, we derived 67.1% of total revenues from our retail coffeehouse
operations. In addition, wholesale and mail order revenue accounted for 20.6 %
of total revenues and franchise revenues counted for 12.3% of total revenues.

         Retail revenues for the twelve weeks ended March 8, 2000 increased 116%
to $11,235,000 from $5,190,000 for the thirteen weeks ended April 28, 1999. This
increase was primarily a result of the acquisition of Coffee People and also due
to an increase in comparable store sales for the Diedrich Coffee coffeehouses
and the Coffee People coffeehouses. As of March 8, 2000, we operated 100 retail
locations; whereas on April 28, 1999, we operated 40 retail locations. The
percentage increase (decrease) in system-wide comparable store sales was 4.7%
for the Diedrich Coffee coffeehouses, (7.1)% for the Gloria Jean's coffee
stores, 2.1% for the Coffee People concept, and (6.4)% for the Coffee Plantation
concept during the twelve weeks ended March 8, 2000.

         Retail revenues for the thirty-six weeks ended March 8, 2000 increased
107% to $32,670,000 from $15,809,000 for the thirty-nine weeks ended April 28,
1999, principally due to the acquisition of Coffee People and also due to an
increase in comparable store sales for the Diedrich Coffee coffeehouses, the
Gloria Jean's coffee stores and the Coffee People coffeehouses. The percentage
increase (decrease) in system-wide comparable store sales was 5.4% for the
Diedrich Coffee coffeehouses, 2.4% for the Gloria Jean's coffee stores, 0.8% for
the Coffee People concept, and (2.4)% for the Coffee Plantation concept during
the thirty-six weeks ended March 8, 2000.

         Wholesale and other revenues increased 301% to $3,443,000 in the twelve
weeks ended March 8, 2000 from $858,000 for the thirteen weeks ended April 28,
1999. Wholesale and other revenues increased 516% to $14,184,000 in the
thirty-six weeks ended March 8, 2000 from $2,301,000 for the thirty-nine weeks
ended April 28, 1999. These increases reflect the addition of the Gloria Jean's
franchisee operations, which purchase roasted coffee from Diedrich Coffee.

         Franchise revenue increased to $2,067,000 for the twelve weeks ended
March 8, 2000, from $50,000 for the thirteen weeks ended April 28, 1999.
Franchise revenue increased to $5,297,000 for the thirty-six weeks ended March
8, 2000 from $250,000 for the thirty-nine weeks ended April 28, 1999. Franchise
revenue consists of initial franchise fees, franchisee renewal fees, area
development fees and royalties received on sales made at each franchised
location. As of March 8, 2000, we had 2 franchised neighborhood coffeehouses and
260 franchised mall coffee stores. The increase in franchise revenue is
principally due to the franchised coffee stores obtained in our acquisition of
Coffee People.

         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 twelve weeks ended March 8, 2000
increased to $7,890,000 from $2,758,000 for the thirteen weeks ended April 28,
1999. As a percentage of total revenue, cost of sales and related occupancy
costs increased to 47.1% in the twelve weeks ended March 8, 2000 from 45.2% for
the thirteen weeks ended April 28, 1999. Cost of sales and related occupancy
costs for the thirty-six weeks ended March 8, 2000 increased to $25,487,000 from
$8,318,000 for the thirty-nine weeks ended April 28, 1999. As a percentage of
total revenue, cost of sales and related occupancy costs increased to 48.9% in
the thirty-six weeks ended March 8, 2000 from 45.3% for the thirty-nine weeks
ended April 28, 1999. These increases are primarily related to the smaller
margins received on coffee and products sold to franchisees than those sold to
wholesale accounts.

         Store Operating Expenses. Store operating expenses increased to
$5,349,000 for the twelve weeks ended March 8, 2000 from $2,288,000 for the
thirteen weeks ended April 28, 1999. As a percentage of retail and franchise
revenues, store operating expenses decreased to 40.2% in the twelve weeks ended
March 8, 2000 from 43.7% in the thirteen weeks ended April 28, 1999. For the
thirty-six weeks ended March 8, 2000, store operating expenses increased to
$15,971,000 from $6,667,000 for the thirty-nine weeks ended April 28, 1999. As a
percentage of retail and franchise revenues, store operating expenses increased
to 42.1% in the thirty-six weeks ended March 8, 2000 from 41.5% in the
thirty-nine weeks ended April 28, 1999. This increase can be attributed to an
increase in labor expenses due to additional staff training at the store level
as well as the addition of the Coffee People stores located in Oregon. Oregon
has a higher minimum wage compared to states in which we were operating during
the prior year.

         Other Operating Expenses. Other operating expenses (those associated
with wholesale and other revenues) increased to $375,000 for the twelve weeks
ended March 8, 2000 from $158,000 for the thirteen weeks ended April 28, 1999.
These expenses, as a percentage of the revenues from the wholesale division,
decreased to 10.9% from 18.3%. For the thirty-six weeks ended March 8, 2000,
other operating expenses, as a percentage of the revenues from the wholesale
division, decreased to 7.4% from 21.6% for the thirty-nine weeks ended April 28,
1999. These decreases can be primarily attributed to a larger revenue base with
the addition of the Gloria Jean's franchisees.

         Depreciation and Amortization. Depreciation and amortization increased
to $901,000 for the twelve weeks ended March 8, 2000 from $507,000 for the
thirteen weeks ended April 28, 1999. As a percentage of total revenue,
depreciation and amortization decreased to 5.4% in comparison to 8.3% for the
thirteen weeks ended April 28, 1999. Depreciation and amortization increased to
$2,540,000 for the thirty-six weeks ended March 8, 2000 from $1,504,000 for the
thirty-nine weeks ended April 28, 1999. As a percentage of total revenue,
depreciation and amortization decreased to 4.9% for the thirty-six weeks ended
March 8, 2000 in comparison to 8.2% for the thirty-nine weeks ended April 28,
1999.

         General and Administrative Expenses. General and administrative
expenses increased to $1,919,000 for the twelve weeks ended March 8, 2000 from
$857,000 for the thirteen weeks ended April 28, 1999. As a percentage of total
revenue, general and administrative expenses decreased to 11.5% from 14.1% in
the thirteen weeks ended April 28, 1999. As a percentage of net revenues,
general and administrative expenses decreased to 11.6% for the thirty-six weeks
ended March 8, 2000 from 15.2% for the thirty-nine weeks ended April 28, 1999.
These decreases in general and administrative expenses as a percentage of total
revenue were primarily a result of cost savings incurred with the acquisition
due to the result of the elimination of management personnel who were not
essential to our growth strategy.

         Interest Expense. Interest expense increased to $279,000 for the twelve
weeks ended March 8, 2000 from $96,000 for the thirteen weeks ended April 28,
1999. For the thirty-six weeks ended March 8, 2000, interest expense increased
to $893,000 from $283,000 for the thirty-nine weeks ended April 28, 1999. These
increases are a result of the $12 million term loan, which funded on July 7,
1999.

LIQUIDITY AND CAPITAL RESOURCES

         We have funded our capital requirements in recent years principally
through public and private placements of our common stock and long-term debt. We
had working capital deficit of $832,349 as of March 8, 2000 compared to working
capital deficit of $2,439,000 as of June 30, 1999. Cash provided by (used in)
operating activities for the thirty-six weeks ended March 8, 2000 totaled
$217,476 as compared to ($656,558) for the thirty-nine weeks ended April 28,
1999.


                                       14
<PAGE>   15

         Net cash used in investing activities for the thirty-six weeks ended
March 8, 2000 totaled $25,346,875 which was primarily used for the acquisition
of Coffee People. Net cash provided by financing activities for the thirty-six
weeks ended March 8, 2000 totaled $28,645,953 which consisted of proceeds from
the issuance of common stock and long-term debt, reduced by the $8,308,000
repayment of long-term debt and capital lease obligations.

         Our management has continued to focus on our long-term growth strategy
which has resulted in certain operating expenses. We recently added several key
executives to our management team to help us achieve these long-term goals. As a
result, we incurred additional operating expenses in the twelve weeks ended
March 8, 2000, and it is not likely that we will be profitable for fiscal year
2000. We plan to continue our review of every aspect of our consolidated
operations to determine where changes, improvements and investments need to be
made to build a stronger company.

         As of March 8, 2000, we had $11.3 million of long-term debt, including
current installments, that consisted of a term loan with BankBoston, N.A. that
is secured by pledges of all of our assets and our subsidiaries' stock and was
bearing interest at a rate of 9.03%. The credit agreement with BankBoston, N.A.
also provides for a $3 million revolving credit facility, which we have not
presently drawn down. The term loan and the revolving credit facility both
require quarterly payments and have a final maturity in July 2004. The Company
used the proceeds of the term loan to repay existing indebtedness and to pay
expenses related to the acquisition of Coffee People. The Company intends to use
the remaining proceeds from the revolving credit facility to finance additional
and remodel existing company-owned retail locations and for general corporate
purposes. Amounts outstanding under the credit agreement bear interest, at the
Company's option, at BankBoston's base rate plus 1.25% or an adjusted Eurodollar
rate plus 3.00%. Diedrich Coffee may change the interest rate from the
BankBoston base rate to the adjusted Eurodollar rate at any time with 3 day's
notice and from the adjusted Eurodollar rate to the BankBoston base rate at the
end of each calendar quarter.

         We believe that the credit facility described above will be sufficient
to satisfy our working capital needs at the anticipated operating levels for the
next twelve months.

                      ITEM 3. QUANTITATIVE AND QUALITATIVE
                          DISCLOSURES ABOUT MARKET RISK

         Derivative Instruments. We did not invest in market risk sensitive
instruments in fiscal 1999, the transition period ended June 30, 1999 nor in the
thirty-six weeks ended March 8, 2000. From time to time, however, we enter into
agreements to purchase green coffee in the future at prices to be determined
within two to twelve months of the time of actual purchase. At March 8, 2000
these commitments totaled $3,084,000. These agreements are tied to specific
market prices (defined by both the origin of the coffee and the month of
delivery) but we have significant flexibility in selecting the date of the
market price to be used in each contract. We do not use commodity based
financial instruments to hedge coffee or any other commodity, as we believe
there will continue to be a high probability of maintaining a strong correlation
between increases in green coffee prices and the final selling prices of our
products.

         We have not used derivative financial instruments for any purpose,
including hedging or mitigating interest rate risk.

         New Accounting Pronouncements. In June 1998, the Financial Accounting
Standards Board issues Statement of Financial Accounting Standards No. 133,
"Accounting for Derivative Instruments and Hedging Activities" (SFAS 133). SFAS
133 establishes accounting and reporting standards for derivative instruments
embedded in other contracts and hedging activities. SFAS 133 is effective for
all fiscal quarters of fiscal years beginning after June 15, 2000. Application
of SFAS 133 is not expected to have a material impact on our business, results
of operations or liquidity.

         Market Risk. Our market risk exposure with regard to financial
instruments outstanding as of March 8, 2000 was to changes in an adjusted
Eurodollar rate. We borrowed $12 million on July 7, 1999 in connection with our
acquisition of Coffee People, which bears interest at our option, at
BankBoston's base rate plus 1.25%, or an adjusted Eurodollar rate plus 3.0%.
Diedrich Coffee may convert the interest rate from the BankBoston base rate to
the adjusted Eurodollar rate at anytime with 3 day's notice. We may convert the
interest rate from the adjusted Eurodollar rate to the BankBoston base rate at
the end of each calendar quarter. The $12 million outstanding under the term
loan was bearing interest at the BankBoston base rate plus 1.25% from July 7,
1999 to July 10, 1999 at which time the interest was converted to the adjusted
Eurodollar rate plus 3.0%. At March 8, 2000, the adjusted Eurodollar rate was
6.03%. At March 8, 2000, a hypothetical 100 basis point increase in the rate
would result in additional interest expense of $113,333 on an annualized basis.
The additional interest expense is based upon the outstanding balance of our
long-term debt, and assumes no change in the volume or composition of debt at
March 8, 2000. The credit agreement also provides for a $3 million revolving
line of credit which also bears interest at our option, at BankBoston's base
rate plus 1.25%, or an adjusted Eurodollar rate plus 3.00%. We have not
presently drawn down this revolving line of credit.

                           PART II- OTHER INFORMATION

                            ITEM 1. LEGAL PROCEEDINGS

         In the ordinary course of our business, we may become involved in legal
proceedings from time to time. During the thirty-six week period ending March 8,
2000, no material developments occurred in any material pending legal
proceedings. A discussion of our material pending legal proceedings appears in
our registration statement on Form S-1 (Reg. No. 333-78083) under the heading
"Business - Legal Proceedings."

                            ITEM 5. OTHER INFORMATION

         Minimum Advance Notice of Stockholder Proposals. Diedrich Coffee
stockholders are advised that we must be notified by April 25, 2000, which is 45
days prior to the month and day of mailing last year's proxy statement, of any
proposal or solicitation that any stockholder intends to present at the next
annual meeting of stockholders and which the stockholder has not sought to have
included in our proxy statement for the meeting in accordance with Rule 14a-8
under the Securities Exchange Act of 1934. If a proponent fails to notify us
before the required deadline, management proxies will be allowed to use their
discretionary voting authority when the proposal is raised at the annual
meeting, without any discussion of the matter in the proxy statement.
