EXECUTIVE EMPLOYMENT AGREEMENT

EXHIBIT 10.24

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 John Carbonell (“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 the Customer Practice Group of the Company and shall have the normal duties, responsibilities and authority of the Vice President of the Customer Practice Group, 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 the Customer Practice Group. 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

-1-

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 termination) 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 3 below.

     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

-2-

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 2 or 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 2 or Section 3 of 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 2 or Section 3 from 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 2 and Section 3 do 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

-4-

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 defined herein) or (ii) termination of employment by Executive with Good Reason (as defined herein), in either case within one (1) year of the date on which the Change of Control takes place.
