EXHIBIT A DiamondCluster International, Inc Partner Compensation Program (as amended through November 13, 2003)  1.
    
    Purpose. The purpose of the Companys Partner Compensation Program (the
Program) is to retain and motivate the Companys Partners (as defined
below), provide incentives directly linked to the achievement of the
Companys financial and strategic goals, maintain equity ownership in the
Company by the Partners, and ensure the orderly and disciplined sale of
the Companys shares by the Partners. Any changes to this Program shall
be reviewed and approved by the Board of Directors as provided in Section
9 hereof.2.
    
    Eligibility. Participation in the Program is limited to all individuals
who at the time of such participation have been admitted as Partners (the
Partners) pursuant to the procedures set forth in the Amended and
Restated Partners Operating Agreement, dated the date hereof (the
Partners Operating Agreement). The term Partners shall mean all
Partners affiliated with North America/UK operations. 3. Annual Compensation.  3.1
    
    Base Salary. Each Partner will receive a base salary that is
commensurate with his or her experience and contribution to the Company.
In general, the base salary levels established for the Partners will fall
within the levels set forth on Exhibit A hereto, as amended from time to
time.3.2
    
    Bonus. The Executive Committee (the Executive Committee), with advice
from the Management Committee and , subject to approval by the Board of
Directors or its compensation committee, will determine the amount of any
annual cash bonus available to be distributed to the Partners. Such bonus
will be based on a combination of the Companys and the individual
Partners performance (Bonus).3.3
    
    Target Bonus. Set forth on Appendix A are the target bonuses as a
percentage of base salary and the relative percentages of Company and
individual performance upon which such bonuses will be based established
for each of the Partner levels. The Executive Committee, with the advice
of the Management Committee and subject to approval by the Board of
Directors or its compensation committee, may change the Target Bonus set
forth on Appendix A; provided, that the Partners shall be notified of the
change prior to the beginning of the fiscal year in which such change will
take effect; and provided, further, that any change that is more than ten
percentage points (10%) higher or lower than the previous Target Bonus
shall be approved by a majority of the Partners.3.4
    
    Bonus Pool. Subject to adjustment by the Executive Committee as described
below, the amounts allocated towards payment of the Partners Bonuses (the
Bonus Pool) will generally be funded

subject to approval by the Board of Directors or its compensation
committee, may adjust the funding of the formula described above based on
the Companys financial performance in any given quarter.3.5
    
    Bonus Payments. Any Bonuses paid to the Partners will be based on the
actual funds available in the Bonus Pool, regardless of whether such
amount is less than the Target Bonus. A Partner who commences employment
with the Company or becomes a Partner after the start of the Companys
fiscal year will receive a prorated Bonus, if any is paid, based on the
number of days such Partner is actually employed by Diamond during such
fiscal year. An individual must be an employee and Partner of the Company
on the last day of the fiscal year to which a Bonus relates in order to
qualify for and receive such Bonus.3.6
    
    Shares. Each Partner is eligible to receive an annual grant of Shares,

    Minimum Ownership Requirements. As a general guideline, each Partner
should own throughout the period in which he or she is a Partner a minimum
number of shares of common stock of the Company having an aggregate market
value at least equal to 10% of his or her then current base salary times
the number of years such individual has been a Partner.  6.
    
    Partners Equity Sales Program.  6.1
    
    Objective. The objective of the Partners Equity Sales Program (the
Sales Program) is to provide an orderly and disciplined market for the
sale of Partners Shares. The Sales Program allows Partners to sell their
Shares quarterly in conjunction with the Companys policy of permitting
trades only during specified periods occurring after the public release of
quarterly earnings.6.2
    
    Affiliates and Non-Affiliates. In order to facilitate compliance with
Rule 144 of the Securities Act of 1933, as amended (the Act) for
purposes of the Sales Program the Partners are classified as either
affiliates or non-affiliates within the meaning of Rule 144 of the Act.
The Board of Directors will designate from time to time those Partners who
will be classified as affiliates for these purposes. All other Partners
and former Partners shall be deemed non-affiliates for purposes of Rule
144 of the Act and the Sales Program.6.3
    
    Sales Limitations for Affiliates. All shares of Common stock, including
Pre-Partner Shares (as defined in Section 6.10), owned by Partners who are
classified as affiliates are subject to the Sales Program. The aggregate
amount of such shares that can be sold as part of the Sales Program shall
not exceed (i) any internal limits set by the Company, or (ii) the time
and volume limitations imposed by Rule 144(e)(1) of the Act.6.4
    
    Sales Limitations for Non-Affiliates. For non-affiliate partners, only
            shares of Common Stock, not including any Pre-Partner Shares or open
market purchase shares (which include Employee Stock Purchase Plan shares),
are subject to the Sales Program. Any such shares sold through
the Sales Program must either be registered with the Securities and
Exchange Commission or held for at least two years in order to qualify for
sales pursuant to Rule 144(k) of the Act. The aggregate amount of Shares
that can be sold as part of the Sales Program shall not exceed any
internal limits set by the Company.6.5
    
    Sales Procedure. Prior to the commencement of the Companys quarterly
trading window, any Partner interested in selling Shares through the Sales
Program shall indicate his or her interest in writing, via e-mail, to the
Chief Financial Officer, or such other employee of the Company as may be
designated from time to time, stating the amount of Shares and the minimum
sales price for which that Partner would be interested in selling such
Shares. After public announcement of the Companys earnings press
release, such Partner will be required to confirm, reduce, increase or
decline his or her participation in the Sales Program and indicate the
number of Shares, if any, such Partner is interested in selling. In the
event the aggregate participation level indicated by the Partners is in
excess of the internal limits established by the Company for either the
affiliates and non-affiliates as a single group or as two separate groups
(in each case, a Group), such Partners will participate pro rata based
on the percentage derived by dividing the number of Shares such Partner
desires to sell by the aggregate number of Shares all




---



##### 



participating Partners in a Group desire to sell. In the event the aggregate
participation level indicated by Partners who are affiliates is in excess of
the time and volume limitations set forth in Rule 144 (e)(1) of the Act, such
Partners will participate pro rata among the affiliate group.6.6
    
    Manner of Sale. All Shares sold through the Sales Program will be sold
over a period of up to six-weeks in brokers transactions in compliance
with Rule 144(f) of the Act through a broker or brokers designated by the
Company. The sales price attributed to each Share sold will be the
average price received for all Shares sold during such six-week period.6.7
    
    Transfer Restrictions; Gifts. No Partner shall transfer, assign, pledge
or hypothecate any of his or her Shares in any way, except that a Partner
may transfer any vested Shares (other than Options) by way of gift, will
or trust to a spouse, lineal descendant or ancestor (an Estate
Transfer); provided, that any Estate Transfer shall, unless otherwise
determined by the Executive Committee, be made in accordance with and
subject to the limitations of the Sales Program with the Estate Transferee
agreeing to be bound by the terms of the Sales Program.6.8
    
    Death or Disability of a Partner. Upon the death or permanent disability
of a Partner, such Partners Shares will cease to be subject to the terms
of the Sales Program.6.9
    
    Termination. Upon termination of a Partners employment for any reason,
vested Shares will continue to be subject to the terms of the Sales
Program, except that any unvested Options and Units will expire
immediately. A Partner that was required to purchase Restricted Shares
upon his or her promotion to partner will be reimbursed for all such
unvested Restricted Stock at the lower of (i) the purchase price paid for
such Restricted Stock pursuant to Section 5.1, together with interest, or
(ii) the average of the closing price of one share of Common Stock on the
NASDAQ National Market System for the ten trading days immediately
preceding such Partners last day of employment.6.10
    
    Pre-Partner and Open Market Purchase Shares. Any shares owned by a
Partner and acquired prior to such individual becoming a Partner or
through the exercise of Options received prior to such individual becoming
a Partner (Pre-Partner Shares) and any shares purchased by a Partner in
an open market transaction (including for these purposes shares purchased
under the Companys Employee Stock Purchase Plan), are not, unless
otherwise specified, subject to the terms of the Sales Program.6.11
    
    Exemption for De Minimus Amounts held by Former Partners. Any Partner
who has ceased to be a Partner of the Company or an Affiliate for at least
three years (Former Partner), will no longer be subject to the Sales
Program if he or she satisfies the following de minimus holding
thresholds: Number of years not a Partner

    <50,0004 years
    
    <75,0005 years

longer be subject to the Sales Program.

    Rule 10b5-1 Plans. Any Partner may enter into a sales plan with his or
her broker that complies with the requirements of Rule 10b5-1(c)(1)(i)(B)
under the Securities Exchange Act of 1934, provided that such plan is
approved by the Executive Committee and establishes sales volumes in any
given quarterly period that are in accordance with and subject to the
limitations required by the Sales Program.7.
    
    Involuntary Termination. Upon involuntary termination of a Partners
employment (as hereinafter defined), in addition to the terms set forth in
Section 6.9 above, such Partners vesting schedule for any unvested Shares
that were issued upon election as a Partner will be accelerated by one
year as of the date of notice of termination. For purposes of the
Program, involuntary termination means termination for reasons other
than resignation or Cause. A Partner will be deemed to have been
terminated for Cause if terminated for: (i) gross insubordination or a
policy violation that is not cured within 15 days after such Partners
having received notice from the Chief Executive Officer, (ii) criminal
acts relating to the Company or its client affairs, or (iii) intentional
acts which are materially injurious to the Company, including disclosing
confidential information to an unauthorized third party.8.
    
    Administration. The Program shall be administered and interpreted by
the Management Committee. The Management Committee shall be responsible
for the management, operation and administration of the Program. The
Management Committee may designate persons who are Company employees to
oversee the day to day administration of the Program.9.
    
    Amendment. The Program may be amended from time to time by
recommendation of the Executive Committee to the Board of Directors and by
