Dear John:

        This letter sets forth the understanding between you and Diedrich
Coffee, Inc., a Delaware corporation (the "Company"), regarding your role in the
management of the Company (the "Agreement"). Subject to the terms and conditions
set forth herein, we agree as follows:

        1. You are hereby appointed and agree to serve as a director of the
Company and as Chairman of the Board of the Company. Upon your acceptance of
this Agreement, I will resign as Chairman and remain a member of the Company's
Board of Directors (the "Board"). You will be compensated for serving as
Chairman of the Board of the Company with a base salary of $8,333.33 per month
(less all amounts required by law to be withheld or deducted), payable on the
last day of each month (or any pro rata portion thereof for any month of partial
service), for so long as you continue in the role of Chairman of the Board. You
will not be entitled to any other employee benefits and this compensation shall
be in lieu of any other compensation to which you would otherwise be entitled as
a member of the Board, including but not limited to the grant of options under
the Company's Non-Employee Directors Stock Option Plan. You will serve in this
role at the discretion of the Board and your service and compensation may be
terminated by the Board at any time for any reason or no reason, without penalty
or further obligation to you by the Company except as set forth in your Stock
Option Plan and Agreement.

        2. In light of your significant time commitment to the Company and the
fact that you will not have an office at the Company's principal executive
offices, the Company agrees to employ a full-time executive assistant for you at
an annual salary not to exceed $72,000 (less all amounts required by law to be
withheld or deducted). In addition, your executive assistant shall be eligible
for benefits commensurate with other employees in similar positions with the
Company.

        3. Timothy J. Ryan, whom you have introduced to the Board, will be
offered employment as Chief Executive Officer of the Company (the "CEO"),
replacing me as interim Chief Executive Officer. The CEO will enter into a
mutually agreeable employment agreement with the Company which will provide for
compensation of $200,000 per year with an annual incentive program.

        4. The Company shall pay or reimburse you for all reasonable and
necessary travel and other business expenses incurred or paid by you in
connection with the performance of services under this Agreement, consistent
with the Company's policies for other senior executives of the Company.

        5. You and the Company will enter into a Stock Option Plan and
Agreement, in substantially the form attached as Exhibit A hereto, pursuant to
which the Company will grant to you, upon the terms and subject to approval by
the stockholders of the Company and the other conditions set forth therein,
options to purchase 850,000 shares of the Company's Common Stock.

        6. Pursuant to a stock purchase agreement in form satisfactory to you
and the Company, the Company will issue and sell to you and you will purchase
333,333 shares of Common Stock of the Company at $3.00 per share.

        7. In connection with the consummation of the transactions described
above, you and the CEO will be nominated to the Board. The Company will enter
into indemnification agreements with each of you in the form provided to each of
the other directors and executive officers of the Company and you will be
entitled to coverage by the Company's directors and officers insurance policy to
the same extent as other directors and officers of the Company.

        8. The Company shall reimburse you for your reasonable legal and
accounting fees incurred in connection with the negotiation and execution of
this Agreement in an amount not to exceed $10,000.

        9. The Company recognizes that you are presently involved in substantial
other business activities and anticipate becoming involved in additional
business activities while serving as Chairman of the Board of the Company.
Notwithstanding that these other business activities may compete for your time,
the Company agrees that you may in your discretion devote as much of your time
as you determine in business activities other than that of serving as an officer
of the Company. You have, however, indicated to the Company that while serving
as Chairman of the Board of the Company, you anticipate taking an active role in
developing recommendations for Company policies and strategies, communicating
regularly with the executive officers of the Company and supervising the
implementation of such policies and strategies. The Company further recognizes
that your other business interests may involve or relate to restaurants
(although not restaurants whose principal business activity is the sale and
serving of coffee drinks) and that while other business opportunities involving
the restaurant business (other than the coffeehouse business or other businesses
in which the principal activity involves the sale of coffee and coffee
beverages) may become available to you, you will not have any obligation to make
such opportunities available to the Company. The Company hereby waives any and
all rights and claims which it may otherwise have to such business
opportunities.

                                            Chairman of the Board and
