SIEBERT THIS AGREEMENT is entered into effective as of the date of signing by and between CIMA LABS INC., a Delaware corporation (the "Company"), and John M. Siebert, Ph.D. (the "Employee"). WHEREAS the Company desires to engage the Employee in the position of President and Chief Executive Officer to render services for the Company on the terms and conditions set forth in this Agreement; WHEREAS, the Employee desires to be retained by the Company as its President and Chief Executive Officer; and WHEREAS, both parties recognize the critical importance to the Company, its employees, and its investors of preserving the confidentiality of the Company's trade secrets and confidential information and of protecting the Company against competition from former executives or other key employees of the Company following their separation from the Company; NOW, THEREFORE, in consideration of the foregoing premises and the parties' mutual covenants and undertakings contained in this Agreement, the sufficiency of which is hereby acknowledged, the Company and the Employee agree as follows: 1. EMPLOYMENT AND TERM. Subject to the terms and conditions herein provided, the Company hereby continues employment of the Employee, and the Employee hereby accepts employment by the Company, for a term continuing as of January 1, 2001 and thereafter for three (3) years to January 1, 2004. The employment 2 EXHIBIT 10.23 term of the Employee will expire at the expiration of this (3) year employment continuation term, without further obligation for either party. On or before January 1, 2003, the Company expects to indicate to the Employee whether the Company is interested in continuing employment of the Employee with respect to a new employment agreement. Notwithstanding the foregoing, the Company may terminate the Employee's employment for cause and without notice and without further obligation of any kind to the Employee. For purposes of this Agreement, "cause" means: (a) any felony conviction; (b) use of intoxicating beverages or chemical abuse that negatively affects job performance (following at least one written warning); (c) an act or acts of personal dishonesty taken by the Employee and intended to result in personal enrichment of the Employee at the expense of the Company; (d) any material breach of the Employee's obligations under this Agreement; (e) the willful misconduct or gross negligence of the Employee in connection with the performance of his duties, responsibilities, agreements, and covenants hereunder, or his failure to comply with the reasonable rules, regulations, policies, directions, and restrictions as may be established from time to time by the Board of Directors, and which misconduct, negligence, or failure shall continue for a period of thirty (30) days after written notice to the Employee; or 2 3 EXHIBIT 10.23 (f) willful conduct of the Employee which brings discredit to the Company, its products, or its services. It is further agreed that the term of the Employee's employment under this Agreement shall automatically terminate in the event of the Employee's death. In the event the Employee becomes mentally or physically disabled during the term of employment hereunder, his employment under this Agreement shall terminate as of the date such disability is established. As used in this paragraph, the term "disabled" shall have the meaning as set forth in the Americans with Disabilities Act, as amended. Upon termination for disability, the Employee shall be entitled to receive continuation of his base salary (as herein defined) for a period of one hundred eighty (180) days. Upon termination in the event of the Employee's death, the Company shall continue to pay the Employee's base salary (as herein defined) for a period of one hundred eighty (180) days. 2. DUTIES AND REPRESENTATIONS OF THE EMPLOYEE. During the Employee's employment hereunder, he shall serve as the Company's President and Chief Executive Officer. The Employee shall devote his full time, attention, knowledge, and skill exclusively to the loyal service of the Company. The Employee represents and warrants to the Company that: (a) his acceptance of employment under this Agreement and his performance of the duties contemplated herein are not in conflict with any obligation, undertaking, or agreement between the Employee and any third party; and (b) he has not and will not, during the course of his employment with the Company, disclose or utilize without permission, any confidential or proprietary information, trade 3 4 EXHIBIT 10.23 secrets, materials, documents, or property owned by any third party. The Company through the Compensation Committee expects to evaluate the Employee's performance every twelve (12) months during the term of this Agreement. 3. COMPENSATION. The Company shall pay to the Employee the following compensation: (a) BASE SALARY. The Company shall pay to the Employee an annual base salary of $305,000 beginning January 1, 2001, less legally required deductions and withholdings, payable in periodic installments in accordance with the standard payroll practices of the Company in effect from time-to-time. On January 1, 2002, the annual base salary will be adjusted upwards by 5%. On January 1, 2003, the annual base salary will be adjusted upwards from the 2002 increase by an incremental 5%. In the event of change of control of the Company which leads to the termination or separation of the Employee (1) because the position is eliminated, (2) because continuing to work in the position would require the Employee to transfer to a work site outside a 100-mile radius of his work location at the time of change in control and Employee is unwilling to relocate, or because his responsibilities change so substantially that the Employee has effectively been removed from the position held by him prior to the change in control, the Employee will automatically get an additional twelve (12) months of compensation or the remainder of his contract (less any amount of salary received in a subsequent job during such twelve (12) month period or remainder of contract, as applicable), whichever is longer, in addition to the benefits of any corporate severance plan, during which time the terms of the Agreement will remain in full force and effect. 4 5 EXHIBIT 10.23 (b) INCENTIVE BONUS. The Employee will be entitled to receive an incentive bonus award of up to seventy percent (70%) of his base salary depending upon the achievement of objectives defined and agreed to by the Compensation Committee of the Board of Directors prior to the last Board meeting of each calendar year. The award for achievement that occurs against objectives in that year will be agreed-upon by the Compensation Committee and paid before February 1 of the next year. The determination of whether and when any of the objectives are achieved shall be in the reasonable discretion of the Compensation Committee. The determination of any additional incentive bonus programs shall be in the sole discretion of the Compensation Committee. In the event of change of control of the Company, a minimum bonus of $150,000 will be paid for each year of compensation remaining under the terms of this Agreement for which a bonus has not yet been paid. (c) PARTICIPATION IN BENEFIT PLANS. The Employee shall also be entitled to participate in all employee benefit plans or programs of the Company, including any disability and life insurance group plans, to the extent that his position, title, tenure, salary, age, health, and other qualifications make him eligible to participate. The Company will provide a life insurance policy with minimum payout of $500,000 in the event the Employee is killed or disabled during travel which is undertaken in the course of business. (d) VACATION. During the term of the Employee's employment under this Agreement, the Employee shall be entitled to take twenty-five (25) days of vacation per year with pay, at such times as shall be mutually convenient to the Company and the 5 6 EXHIBIT 10.23 Employee. Vacation time may be accumulated throughout the term of this and any prior Agreements. Two weeks before the final Board meeting of each year, the Vice President, CFO will provide the Compensation Committee with a report outlining the Employee's paid time off (PTO) taken and remaining for that year. (e) EMPLOYMENT-RELATED EXPENSES. The Company shall pay or reimburse the Employee for all reasonable and necessary out-of-pocket expenses incurred by him in the performance of his duties under this Agreement, subject to the presentment of appropriate vouchers in accordance with the Company's normal policies for expenses verification. (f) CAR ALLOWANCE. The Employee will be paid a car allowance in the amount of six hundred fifty dollars ($650.00) per month, consistent with the Company's payroll and accounting practices. (g) STOCK OPTION. Subject to the terms of the Company's Equity Incentive Plan, and subject to the Employee executing this document, the Company shall issue to the Employee an incentive stock option to purchase one hundred thousand (100,000) shares of common stock in the Company effective at the date of signing this Agreement. This award will vest as follows: (i) thirty-three percent (34%) of the shares subject to the option will vest on December 31, 2002; (ii) thirty-three percent (33%) of the shares subject to the option will vest on December 31, 2003; (iii) thirty-three percent (33%) of the shares subject to the option will vest on December 31, 2004; subject to accelerated vesting as provided in the Equity Incentive Plan. 6 7 EXHIBIT 10.23 Any payment or benefit hereunder shall be reduced to the extent that, due to the excise tax on excess parachute payments under Section 4999 of the Internal Revenue Code of 1986, such reduction would increase the Employee's after-tax income. The Employee shall determine which payments or benefits shall be so reduced." 4. CONFIDENTIAL INFORMATION. Except as permitted or directed by the Company's Board of Directors, during the term of this Agreement or at any time thereafter, the Employee shall not divulge, furnish, or make accessible to anyone or use in any way (other than in the ordinary course of business of the Compete) any confidential or secret knowledge of the Company which the Employee has acquired or become acquainted with or will acquire or become acquainted with prior to the termination of the period of his employment by the Company, whether developed by himself or by others, concerning any trade secrets, confidential or secret designs, processes, formulae, plans, devices, or materials (whether or not patented or patentable), directly or indirectly useful in any aspect of the business of the Company, any customer or supplier list of the Company, any confidential or secret development or research work of the Company, or any other confidential information or secret aspects of the business of the Company. The Employee acknowledges that the above-described knowledge or information constitutes a unique and valuable asset of the Company and represents a substantial investment of time and expense by the Company and its predecessors, and that any disclosure or other use of such knowledge or information other than for the sole benefit of the Company would be wrong and would cause irreparable harm to the Company. Both during and after the 7 8 EXHIBIT 10.23 term of this Agreement, the Employee will refrain from any acts or omissions that would reduce the value of such knowledge or information to the Company. The foregoing obligations of confidentiality, however, shall not apply to any knowledge or information which is now published or which subsequently becomes generally publicly known in the form in which it was obtained from the Company, other than as a direct or indirect result of a breach of this Agreement by the Employee. 5. RETURN OF PROPRIETARY PROPERTY. The Employee agrees that all property in the Employee's possession belonging to the Company, including without limitation, all documents, reports, manuals, memoranda, computer print-outs, customer lists, credit cards, keys, identification, products, access cards, and all other property relating in any way to the business of the Company are the exclusive property of the Company, even if the Employee authored, created, or assisted in authoring or creating such property. The Employee shall return to the Company all such documents and property immediately upon termination of employment or at such earlier time as the Company may reasonably request. 6. RESTRICTIVE COVENANT. The Employee acknowledges that the Company needs to be protected against the potential for unfair competition and impairment of the Company's good will by the Employee's use of the Company's training, assistance, confidential information, and trade secrets in direct competition with the Company. The Employee therefore agrees that for a period of one (1) year from the date of termination of his employment hereunder, the Employee shall not operate, join, control, be employed by, or participate in ownership, management, operation, or control of, or be 8 9 EXHIBIT 10.23 connected in any manner as an independent contractor, consultant, or otherwise, with any person or organization engaged in any business activity which is the same as, or directly competitive with any business of the Company or any successor of the Company as of the date of the termination of his employment hereunder within the states of the United States of America. The Employee expressly agrees that the provisions of this paragraph 6 shall survive the termination of the Employee's employment hereunder or the termination of this Agreement for a period of one (1) year, whether such termination be voluntary or involuntary or with or without cause. 7. COVENANT NOT TO RECRUIT. The Employee recognizes that the Company's work force constitutes an important and vital aspect of its business. The Employee agrees that for a period of one (1) year following the termination of his employment hereunder or the termination of this Agreement for any reason whatsoever, he shall not recruit, or assist anyone else in the solicitation of, any of the Company's then current employees to terminate their employment with the Company and to become employed by any business enterprise with which the Employee may then be associated or connected, whether as an owner, employee, partner, agent, investor, consultant, contractor or otherwise. 8. ASSIGNMENT. The rights and obligations of the Company under this Agreement shall inure to the benefit of and shall be binding upon the successors and assigns of the Company.

CONSTRUCTION AND SEVERABILITY. The validity, interpretation, performance, and enforcement of this Agreement shall be governed by the laws of the State of Minnesota. In the event any provision of this Agreement shall be held illegal or invalid for any reason, said illegality or invalidity will not in any way affect the legality or validity of any other provision hereof.
