EXHIBIT 10.26

EXECUTIVE EMPLOYMENT AGREEMENT

THIS EXECUTIVE EMPLOYMENT AGREEMENT (this Agreement) is made as of
January 15, 2001, between Cysive, Inc., a Delaware corporation (the Company),
and Gene Willingham (Executive).

The parties hereto agree as follows:

1.     Employment. The Company agrees to employ Executive and Executive
accepts such employment for the period beginning as of the date hereof and
ending on the fourth anniversary of the date hereof or upon Executives earlier
separation pursuant to Section 1(d)hereof (the Employment Period); provided,
however, that the Employment Period shall automatically be renewed for an
additional two year period commencing on the fourth anniversary of the date
hereof unless either the Company or the Executive gives the other at least 60
days written notice prior to the fourth anniversary of its desire to terminate
this Agreement.

(a)       Position and Duties. During the Employment Period, Executive shall
serve as Vice President of Product Solutions of the Company and shall have the
normal duties, responsibilities and authority of the Vice President of Product
Solutions, subject to the power of the Chief Executive Officer or the Companys
board of directors (the Board) to expand or limit such duties,
responsibilities and authority and to override actions of the Vice President of
Product Solutions. Executive shall report to the Chief Executive Officer and
Executive shall devote his best efforts and his full business time and
attention to the business and affairs of the Company and its subsidiaries.

(b)       Salary, Bonus and Benefits. For the calendar year 2001, the Company
will pay Executive a base salary of $160,000 per annum (the Annual Base
Salary). During 2001, Executive shall receive the Base Bonus when and if the
Company achieves certain performance targets, and, additionally, Executive may
also receive an Accelerated Bonus if and when the Company exceeds those certain
performance targets, subject to the discretion of the Chief Executive Officer
(the Bonus). The Base Bonus means an amount equal to the product of 0.75
multiplied by the Annual Base Salary and Accelerated Bonus means an additional
amount as determined by the Chief Executive Officer. Executives Annual Base
Salary and Bonus for any partial year will be prorated based upon the number of
days elapsed in such year. In addition, during the Employment Period,
Executive will be entitled to such other benefits approved by the Chief
Executive Officer and made available to the Companys senior executives,
including, but not limited to, vacation time, tuition reimbursement,
reimbursement of business expenses and healthcare benefits.

(c)       Stock Options. Executive shall be eligible to receive grants of
options to purchase the Companys common stock from time to time during the
Employment Period, the granting of which will remain subject to the sole and
absolute discretion of the Chief Executive Officer. All terms and conditions
of a grant of stock options shall be governed by the applicable stock option
grant agreement.

(d)       Separation. Executives employment by the Company during the
Employment Period will continue until Executives resignation at any time or
until Executives

disability or death or until the Chief Executive Officer terminates
Executives Employment at any time during the Employment Period (the
Separation). If the Employment Period is terminated by the Executive without
Good Reason, then the termination will be effective thirty (30) days after the
date of delivery of written notice of termination. If the Employment Period is
terminated by the Board or the Chief Executive Officer without Cause or by the
Executive with Good Reason, then the termination will be effective fifteen (15)
days after the date of delivery of written notice of termination. If the
Employment Period is terminated by the Board or the Chief Executive Officer
with Cause, termination will be effective fifteen (15) days after the date of
delivery of written notice of termination. If the Employment Period is
terminated by the Board or the Chief Executive Officer with Cause or by the
Executive without Good Reason, then the Executive shall be entitled to receive
his Annual Base Salary and all fringe benefits pro-rated through the effective
date of termination. If the Employment Period is terminated by the Board or
the Chief Executive Officer without Cause or by the Executive with Good Reason,
then the Executive shall be entitled to receive his Annual Base Salary, the
Base Bonus (in effect at the time of execution) and all fringe benefits for one
year from the effective date of termination (such payments and fringe benefits
are referred hereinafter as the Severance Payment) payable over time in
accordance with normal payroll practices. If the Employment Period is
terminated due to death, then the Annual Base Salary and medical insurance will
be continued through the next full calendar month following the month in which
the Executive died. If the Employment Period is terminated due to Disability
(as defined herein), then the Annual Base Salary, medical insurance and
disability insurance will be continued until the last day of the six-month
period following the Disability; provided, however, that such Annual Base
Salary shall be reduced by the amount of any disability income payments made to
the Executive during such six-month period from any insurance or other policies
provided by the Company. In the event Executive is owed amounts under this
Section 1(d), such amounts may be withheld by the Company upon a breach or
threatened breach of the terms and conditions of Section 3below.

2.     Confidential Information

(a)      Executive acknowledges that the Company is engaged in the business of
software engineering and it builds and implements complex and highly customized
systems supporting large scale electronic commerce businesses (the Business).
Executive further acknowledges that the Business and its continued success
depend upon the use and protection of a large body of confidential and
proprietary information, and that he holds a position of trust and confidence
by virtue of which he necessarily possesses, has access to and, as a
consequence of his signing this Agreement, will continue to possess and have
access to, highly valuable, confidential and proprietary information of the
Company not known to the public in general, and that it would be improper for
him to make use of this information for the benefit of himself and others. All
of such confidential and proprietary information now existing or to be
developed in the future will be referred to in this Agreement as Confidential
Information. This includes, without limitation, information relating to the
nature and operation of the Business or any other business conducted by the
Company, the persons, firms and corporations which are customers or active
prospects of the Company during Executives employment by the Company, the
Business development transition and transformation plans, methodology and
methods of doing business, strategic, acquisition, marketing and expansion
plans, including plans regarding planned and potential acquisitions and sales,
financial and business plans, employee lists, numbers and location of sales
representatives, new and existing programs and services (and those under

development), prices and terms, customer service, integration processes
requirements, costs of providing service, support and equipment and equipment
maintenance costs. Confidential Information shall not include any information
that has become generally known to, and available for use by, the public other
than as a result of Executives acts or omissions in contravention of the terms
and provisions of this Agreement.

(b)      Disclosure of any Confidential Information of the Company shall not be
prohibited if such disclosure is directly pursuant to a valid and existing
order of a court or other governmental body or agency within the United States;
provided, however, that (i) Executive shall first have given prompt notice to
the Company of any such possible or prospective order (or proceeding pursuant
to which any such order may result) and (ii) Executive shall afford the Company
a reasonable opportunity to prevent or limit any such disclosure.

(c)      During the Employment Period and for a period of three (3) years
thereafter, Executive will preserve and protect as confidential all of the
Confidential Information known to Executive or at any time in Executives
possession. In addition, during the Employment Period and at all times
thereafter, Executive will not disclose to any unauthorized person or use for
his own account any of such Confidential Information without the Boards or the
Chief Executive Officers written consent. Executive agrees to deliver to the
Company at a Separation, or at any other time the Company may request in
writing, all memoranda, notes, plans, records, reports and other documents (and
copies thereof) containing or otherwise relating to any of the Confidential
Information (including, without limitation, all acquisition prospects, lists
and contact information) which he may then possess or have under his control.
Executive acknowledges that all such memoranda, notes, plans, records, reports
and other documents are, and at all times shall be and shall remain, the
property of the Company.

(d)      Executive will fully comply with any agreement reasonably required by
any of the Companys customers, both actual and potential, business partners,
suppliers or contractors with respect to the protection of the confidential and
proprietary information of such persons or entities.

3.     Noncompetition and Nonsolicitation. Executive acknowledges that in the
course of his employment with the Company, he will become familiar with the
Confidential Information concerning the Company and the Business, including
without limitation customer lists and contacts, and that his services will be
of special, unique and extraordinary value to the Company. Executive agrees
that the Company has a protectable interest in the Confidential Information
acquired by Executive during the course of his employment with the Company.
Therefore, Executive agrees to the following:

(a)      Noncompetition. So long as Executive is employed or affiliated with
the Company and for an additional one (1) year thereafter, he shall not,
anywhere within 50 miles of any of the Companys offices in the United States,
directly or indirectly own, manage, control, participate in, consult with,
render services for, or in any manner engage in, any customer or any business
actually competing with the Business of the Company, in whole or in part, at
the time of termination.

(b)      Nonsolicitation. So long as Executive is employed or affiliated with
the

-3-

##### 



Company and for an additional two (2) years thereafter, the Executive
shall not directly or indirectly through another entity (i) induce or attempt
to induce any employee of the Company to leave the employ of the Company, or in
any way interfere with the relationship between the Company and any employee
thereof, (ii) hire any person who was an employee of the Company within one
year prior to the time such employee was hired by the Executive, (iii) induce
or attempt to induce any owner of a customer, supplier, licensee or other
business relation of the Company to cease doing business with the Company or in
any way interfere with the relationship between any such customer, supplier,
licensee or business relation and the Company, or (iv) directly or indirectly
acquire or attempt to acquire an interest in any business relating to the
Business of the Company and with which, to Executives knowledge, the Company
has entertained discussions or has requested and received information relating
to the acquisition of such Business by the Company in the one-year period
immediately preceding a Separation.

(c)      Enforcement. If, at the time of enforcement of Section 2or Section 3
of this Agreement, a court holds that the restrictions stated herein are
unreasonable under the circumstances then existing, the parties hereto agree
that the maximum duration, scope or geographical area reasonable under such
circumstances shall be substituted for the stated period, scope or geographical
area and that the court shall be allowed to revise the restrictions contained
herein to cover the maximum duration, scope and geographical area permitted by
law. Because Executives services are unique and because Executive has access
to Confidential Information, the parties hereto agree that money damages would
be an inadequate remedy for any breach of this Agreement. Therefore, in the
event of a breach or threatened breach of Section 2or Section 3of this
Agreement, the Company or any of its successors or assigns shall, in addition
to other rights and remedies existing in its favor, be entitled to specific
performance and/or injunctive or other relief in order to enforce, or prevent
any violations of, the provisions of Section 2or Section 3from any court of
competent jurisdiction.

(d)      Additional Acknowledgments. Executive acknowledges that the
provisions of this Section are in consideration of: (i) employment with the
Company and (ii) additional good and valuable consideration as set forth in
this Agreement. Executive expressly agrees and acknowledges that the
restrictions contained in Section 2and Section 3do not preclude Executive
from earning a livelihood, nor does it unreasonably impose limitations on
Executives ability to earn a living. In addition, Executive agrees and
acknowledges that the potential harm to the Company of its non-enforcement
outweighs any harm to the Executive of its enforcement by injunction or
otherwise. Executive acknowledges that he has carefully read this Agreement
and has given careful consideration to the restraints imposed upon the
Executive by this Agreement, and is in full accord as to their necessity for
the reasonable and proper protection of the Confidential Information.
Executive expressly acknowledges and agrees that each and every restraint
imposed by this Agreement is reasonable with respect to subject matter, time
period and geographical area.

(e)      Executives Representations and Warranties. Executive represents and
warrants that he has full right and authority to enter into this Agreement and
fully perform his obligations hereunder, that he is not subject to any
non-competition agreement that would prevent or restrict him in any way from
rendering the services hereunder anywhere in the world, and that his past,
present and anticipated future activities have not, and will not, infringe on
the proprietary rights of others. Executive further represents and warrants
that he is not obligated

under any contract (including licenses, covenants or commitments of any
nature) or other agreement, or subject to any judgment, decree or order of any
court or administrative agency which would conflict with his obligation to use
his best efforts to promote the interests of the Company or which would
conflict with the Companys business as conducted or proposed to be conducted.
Neither the execution nor delivery of this Agreement, nor the carrying on of
the Companys business as an officer, director or employee by Executive, will
conflict with or result in a breach of the terms, conditions or provisions of,
or constitute a default under, any contract, covenant or instrument under which
Executive is now obligated.

(f)      Notwithstanding the foregoing, the terms and conditions of Section
3(a)shall be inoperative and shall have no further effect, and Executive shall
have no continuing obligation with respect thereto, upon (A) the occurrence of
an event which constitutes a Change of Control (as defined herein) of the
Company and (B)(i) the termination of Executives employment without Cause (as
