Exhibit 10.1 AHC I ACQUISITION CORP. 1998 STOCK OPTION PLAN A. PURPOSES AHC I ACQUISITION CORP., a Delaware corporation (the "Company"), desires to afford certain of its key employees and directors, and the key employees and directors of any parent corporation or subsidiary corporation of the Company now existing or hereafter formed or acquired, who are responsible for the continued growth of the Company, an opportunity to acquire a proprietary interest in the Company, and thus to create in such key employees an increased interest in and a greater concern for the welfare of the Company and its subsidiaries. The Company, by means of this 1998 Stock Option Plan (the "Plan"), seeks to retain the services of persons now holding key positions and to secure the services of persons capable of filling such positions. The stock options ("Options") offered pursuant to the Plan are a matter of separate inducement and are not in lieu of any salary or other compensation for the services of any key employee. The Options granted under the Plan are intended to be either incentive stock options ("Incentive Options") within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), or options that do not meet the requirements of Incentive Options ("Non-Qualified Options"). The Company makes no warranty, however, as to the qualification of any Option as an Incentive Option. 2. NUMBER OF SHARES SUBJECT TO THE PLAN The total number of shares of common stock of the Company which may be purchased or acquired pursuant to the exercise of Options granted under the Plan shall not exceed, in the aggregate, 80,000 shares of the authorized common stock, par value $.01 per share, of the Company (the "Shares"); provided, that the maximum number of Shares which may be purchased or acquired pursuant to the exercise of Options granted to one key employee or director under the Plan is 32,500. Shares available for issuance acquired under the Plan may be either authorized but unissued Shares or Shares of issued stock held in the Company's treasury, or both, at the discretion of the Company. If and to the extent that Options granted under the Plan expire or terminate without having been exercised, the Shares covered by such expired or terminated Options may again be subject to an Option under the Plan. Except as provided in Article 18 and subject to Article 3, the Company may, from time to time during the period beginning on June 17, 1998 (the "Effective Date"), the date of approval by the board of directors of the Company (the "Board of Director's"), and ending on June 16, 2008, (the "Termination Date"), grant Incentive Options and Non-Qualified Options to certain key employees of the Company or any subsidiary corporation of the Company under the terms hereinafter set forth. As used in the Plan, the terms "parent corporation" and "subsidiary corporation" shall mean a corporation within the definitions of such terms contained in Sections 424(e) and 424(f) of the Code, respectively. 3. ADMINISTRATION The Board of Directors shall administer the Plan, provided that the Board of Directors may, from time to time, designate from any of its members a Compensation Committee, which shall be the Compensation Committee of the Board of Directors (the "Committee"), to administer the Plan. A majority of the members of the Committee shall constitute a quorum, and the act of a majority of the members of the Committee shall be the act of the Committee. Any member of the Committee may be removed at any time either with or without cause by resolution adopted by the Board of Directors, and any vacancy on the Committee at any time may be filled by resolution adopted by the Board of Directors. If the Board of Directors administers the Plan, then reference herein, or in any option agreement granting Options pursuant to the Plan, to the Committee shall mean the Committee or the Board of Directors, as appropriate. Subject to the express provisions of the Plan, the Committee shall have authority, in its discretion, to determine the key employees to whom Options shall be granted (the "Optionholders"), the time when such Options shall be granted, the number of Shares which shall be subject to each Option, the purchase price or exercise price of each Option, the period(s) during which such Options shall be exercisable (whether in whole or in part) and the other terms and provisions thereof (which need not be identical). Subject to the express provisions of the Plan, the Committee also shall have authority to construe the Plan and the Options granted thereunder, to amend the Plan and the Options granted thereunder, to prescribe, amend and rescind rules and regulations relating to the Plan, to determine the terms and provisions of the Options (which need not be identical) granted thereunder and to make all other determinations necessary or advisable for administering the Plan. The Committee may establish performance standards for determining the periods during which Options shall be exercisable, including without limitation standards based on the earnings of the Company and its subsidiaries for various fiscal periods. The Committee shall define such performance criteria and, from time to time, the Committee in its sole discretion and in administering the Plan may make adjustments to such performance criteria for any fiscal period so that extraordinary or unusual charges or credits, acquisitions, mergers, consolidations, and other corporate transactions and other elements of or factors influencing the calculations of earnings or any other performance standard do not distort or affect the operation of the Plan in a manner inconsistent with the achievement of its purpose. The determination of the Committee on matters referred to in this Article 3 shall be conclusive. The Committee may employ such legal counsel, consultants and agents as it may deem desirable for the administration of the Plan and may rely upon any opinion or computation received from any such legal counsel, consultant or agent. Expenses incurred by the Committee in the engagement of such counsel, consultant or agent shall be paid by the Company. No member or former member of the Committee shall be liable for any action or determination made in good faith with respect to the Plan or any award of Options granted hereunder. 4. ELIGIBILITY Options may be granted only to key employees or directors of the Company or any parent or subsidiary corporation of the Company. The Plan does not create a right in any employee or director to participate in the Plan, nor does it create a right in any employee or director to have any Options granted to him or her. 5. OPTION PRICE AND PAYMENT The price for each Share purchasable under any Option granted hereunder shall be such amount as the Committee shall determine in good faith to be the fair market value (as defined below) per Share at the date the Option is granted; provided, however, that the exercise price shall not be less than $1.00 per share; and provided further, that in the case of an Incentive Option granted to a key employee who, at the time such Incentive Option is granted, owns stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any subsidiary corporation or parent corporation of the Company, the purchase price for each Share shall not be less than one hundred ten percent (110%) of the fair market value per Share at the date the Incentive Option is granted. In determining the stock ownership of a key employee for any purpose under the Plan, the rules of Section 424(d) of the Code shall be applied, and the Committee may rely on representations of fact made to it by the key employee and believed by it to be true. For purposes of the Plan, "fair market value," with respect to any date of determination, means: (i) if the Shares are listed or admitted to trading on a national securities exchange in the United States or reported through The Nasdaq Stock Market ("Nasdaq") then the closing sale price on such exchange or Nasdaq on such date or, if no trading occurred or quotations were available on such date, then on the closest preceding date on which the Shares were traded or quoted; or (ii) if not so listed or reported but a regular, active public market for the Shares exists (as determined in the sole discretion of the Committee, whose decision shall be conclusive and binding), then the average of the closing bid and ask quotations per Share in the over-the-counter market for such Shares in the United States on such date or, if no such quotations are available on such date, then on the closest date preceding such date. For purposes of the foregoing, a market in which trading is sporadic and the ask quotations generally exceed the bid quotations by more than 15% shall not be deemed to be a "regular, active public market." If the Committee determines that a regular, active public market does not exist for the Shares, the Committee shall determine the fair market value of the Shares in its good faith judgment based on the total number of shares of Common Stock then outstanding, taking into account all outstanding options, warrants, rights or other securities exercisable or exchangeable for, or convertible into, shares of Common Stock. For purposes of this Plan, the determination by the Committee of the fair market value of a Share shall be conclusive. Upon the exercise of an Option granted hereunder, the Company shall cause the purchased Shares to be issued only when it shall have received the full purchase price for the Shares in cash or by certified check; provided, however, that in lieu of cash, the holder of an Option may, if and to the extent the terms of such Option so provide and to the extent permitted by applicable law, exercise an Option in whole or in part, by delivering to the Company (a) shares of common stock of the Company (in proper form for transfer and accompanied by all requisite stock transfer tax stamps or cash in lieu thereof) owned by such holder having a fair market value equal to the exercise price applicable to that portion of the Option being exercised or (b) such other form of payment as the Committee shall permit in its sole discretion at the time of grant of the Option. 6. USE OF PROCEEDS The cash proceeds of the sale of Shares pursuant to the Plan are to be added to the general funds of the Company and used for its general corporate purposes as the Board of Directors shall determine. 7. TERM OF OPTIONS AND LIMITATIONS ON THE RIGHT OF EXERCISE An Option shall be exercisable at such times, in such amounts and during such period or periods as the Committee shall determine at the date of the grant of such Option; provided, however, that an Option shall not be exercisable after the expiration of ten (10) years from the date such Option is granted; and provided, further, that an Incentive Option granted to a key employee who, at the time such Incentive Option is granted, owns stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any subsidiary corporation or parent corporation of the Company, shall not be exercisable after the expiration of five (5) years from the date such Incentive Option is granted. The Committee shall have the right to accelerate, in whole or in part, from time to time, conditionally or unconditionally, rights to exercise any Option granted hereunder. To the extent that an Option is not exercised within the period of exercisability specified therein, it shall expire as to the then unexercised part. Except as otherwise provided under the Code, to the extent that the aggregate fair market value of stock for which Incentive Options (under all stock option plans of the Company and of any parent corporation or subsidiary corporation of the Company) are exercisable for the first time by a key employee during any calendar year exceeds one hundred thousand dollars ($100,000), such Options shall be treated as Non-Qualified Options. For purposes of this limitation, (a) the fair market value of the stock is determined as of the time the Option is granted, and (b) Options will be taken into account in the order in which they were granted. In no event shall an Option granted hereunder be exercised for a fraction of a Share. 8. EXERCISE OF OPTIONS Options granted under the Plan shall be exercised by the Optionholder as to all or part of the Shares covered thereby by the giving of written notice of the exercise thereof to the Corporate Secretary of the Company at the principal business office of the Company, specifying the number of Shares to be purchased and specifying a business day not more than fifteen (15) days from the date such notice is given for the payment of the purchase price against delivery of the Shares being purchased. Subject to the terms of Articles 13, 14, 15 and 16, the Company shall cause certificates for the Shares so purchased to be delivered to the Optionholder at the principal business office of the Company, against payment of the full purchase price, on the date specified in the notice of exercise. 9. NON-TRANSFERABILITY OF OPTIONS No Option granted hereunder shall be transferable, whether by operation of law or otherwise, other than by will or the laws of descent and distribution and any Option granted hereunder shall be exercisable during the lifetime of the Optionholder only by such Optionholder. Except to the extent provided above, Options may not be assigned, transferred, pledged, hypothecated or disposed of in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process, and any purported assignment in contravention hereof shall be void and of no effect. Notwithstanding the foregoing, at the discretion of the Committee, a Non-Qualified Option may be transferred by a key employee solely to such key employee's spouse, siblings, parents, children and grandchildren or trusts for the benefit of such persons or partnerships, corporations, limited liability companies or other entities owned solely by such persons, subject to any restrictions included in the award of the Non-Qualified Option. 10. TERMINATION OF EMPLOYMENT Upon termination of employment of any Optionholder with the Company and all subsidiary corporations, an Option previously granted to the Optionholder, unless otherwise specified by the Committee in the Option, shall, to the extent not theretofore exercised, terminate and become null and void, provided that: (a) if the Optionholder shall die while in the employ of such corporation or during either the six (6) month or thirty (30) day period, whichever is applicable, specified in clauses (b) and (c) below, and at a time when such Optionholder was entitled to exercise an Option as herein provided, the legal representative of such Optionholder, or such person who acquired such Option by bequest or inheritance or by reason of the death of the Optionholder, shall have the right to exercise such Option so granted, to the extent not theretofore exercised, in respect of any or all of such number of Shares that such Optionholder is entitled to purchase pursuant to such Option at the time of such Optionholder's death, at any time up to and including one (1) year after the date of death; (b) if the employment of any Optionholder to whom such Option shall have been granted shall terminate by reason of the Optionholder's disability (as defined below), and while such Optionholder is entitled to exercise such Option as herein provided, such Optionholder shall have the right to exercise such Option so granted, to the extent not theretofore exercised, in respect of any or all of such number of Shares that such Optionholder is entitled to purchase pursuant to such Option at the time of such termination, at any time up to and including six (6) months after the date of termination of employment; and (c) if the employment of any Optionholder to whom such Option shall have been granted shall terminate by reason of dismissal by the employer other than for cause (as defined below), and while such Optionholder is entitled to exercise such Option as herein provided, such Optionholder shall have the right to exercise such Option so granted, to the extent not theretofore exercised, in respect of any or all of such number of Shares that such Optionholder is entitled to purchase pursuant to such Option at the time of such termination, at any time up to and including thirty (30) days after the date of termination of employment. If an Optionholder (i) voluntarily terminates his or her employment, or (ii) is discharged for cause, any Option granted hereunder shall, unless otherwise specified by the Committee in the Option, forthwith terminate with respect to any unexercised portion thereof. If an Option granted hereunder shall be exercised by the legal representative of a deceased or disabled Optionholder, or by a person who acquired an Option granted hereunder by bequest or inheritance or by reason of death of any Optionholder, written notice of such exercise shall be accompanied by a certified copy of letters testamentary or equivalent proof of the right of such legal representative or other person to exercise such Option. For all purposes of the Plan, the term "for cause" shall mean, (i) with respect to an Optionholder who is a party to a written employment agreement with the Company, which agreement contains a definition of "for cause" or "cause" (or words of like import) for purposes of termination of employment thereunder by the Company, "for cause" or "cause" as defined in the most recent of such agreements, or (ii) in all other cases, as determined by the Committee, in its sole discretion, that one or more of the following has occurred: (A) any intentional or willful failure, or failure due to bad faith, by such Optionholder to substantially perform his or her employment duties which shall not have been corrected within 30 days following written notice thereof, (B) any misconduct by such Optionholder which is significantly injurious to the Company or any of its subsidiaries or affiliates, (C) any breach by such Optionholder of any covenant contained in the instrument pursuant to which an Option is granted, (D) such Optionholder's conviction of, or entry of a plea of nolo contendere in respect of, any felony or a misdemeanor which results in, or is reasonably expected to result in, economic or reputational injury to the Company or any of its subsidiaries or affiliates. For all purposes of the Plan, the term "disability" means (i) with respect to an Optionholder who is a party to a written employment agreement with the Company, which agreement contains a definition of "disability" or "permanent disability" (or words of like import) for purposes of termination of employment thereunder by the Company, "disability" or "permanent disability" as defined in the most recent of such agreements, or (ii) in all other cases, means such Optionholder's inability to perform substantially his or her duties and responsibilities to the Company or any of its subsidiaries by reason of physical or mental illness, injury, infirmity or condition: (A) for a continuous period for 120 days or one or more periods aggregating 150 days in any twelve-month period; (B) at such time as such Optionholder is eligible to receive disability income payments under any long-term disability insurance plan maintained by the Company or any of its subsidiaries; or (C) at such earlier time as such Optionholder or the Company submits medical evidence, in the form of a physician's certification, that such Optionholder has a physical or mental illness, injury, infirmity or condition that will likely prevent such Optionholder from substantially performing his duties and responsibilities for 120 days or longer. A termination of employment shall not be deemed to occur by reason of (i) the transfer of an Optionholder from employment by the Company to employment by a subsidiary corporation of the Company or (ii) the transfer of an Optionholder from employment by a subsidiary corporation of the Company to employment by the Company or by another subsidiary corporation of the Company. Notwithstanding anything to the contrary contained in this Article 10, in no event shall any person be entitled to exercise any Option after the expiration of the period of exercisability of such Option as specified therein. 11. ADJUSTMENT OF SHARES; EFFECT OF CERTAIN TRANSACTIONS In the event of any change in the outstanding Shares through merger, consolidation, reorganization, recapitalization, stock dividend, stock split, reverse split, split-up, split-off, spin-off, combination of shares, exchange of shares, or other like change in capital structure of the Company, the Committee shall make such adjustments to each outstanding Option that it, in its sole discretion, deems appropriate. The term "Shares" after any such change shall refer to the securities, cash and/or property then receivable upon exercise of an Option. In addition, in the event of any such change, the Committee shall make any further adjustment as may be appropriate to the maximum number of Shares which may be acquired under the Plan pursuant to the exercise of Options, the maximum number of Shares for which Options may be granted to any individual under the Plan, the minimum exercise price per Share for Options to be granted under the Plan, and the number of Shares and prices per Share subject to outstanding Options as shall be equitable to prevent dilution or enlargement of rights under such Options, and the determination of the Committee as to these matters shall be conclusive. 12. RIGHT TO TERMINATE EMPLOYMENT The Plan shall not impose any obligation on the Company or on any subsidiary corporation thereof to continue the employment of any Optionholder and it shall not impose any obligation on the part of any Optionholder to remain in the employ of the Company or of any subsidiary corporation thereof. 13. SECURITIES LAW MATTERS Except as hereinafter provided, the Committee may require an Optionholder, as a condition upon exercise of any Option granted hereunder, to execute and deliver to the Company a written statement, in form satisfactory to the Committee, in which the Optionholder represents and warrants that Shares are being acquired for such Optionholder's own account for investment only and not with a view to the resale or distribution thereof. The Optionholder shall, at the request of the Committee, be required to represent and warrant in writing that any subsequent resale or distribution of Shares by the Optionholder shall be made only pursuant to either (i) a Registration Statement on an appropriate form under the Securities Act of 1933, as amended (the "Securities Act"), which Registration Statement has become effective and is current with regard to the Shares being sold, or (ii) a specific exemption from the registration requirements of the Securities Act, but in claiming such exemption the Optionholder shall, prior to any offer of sale or sale of such Shares, obtain a prior favorable written opinion of counsel, in form and substance satisfactory to counsel for the Company, as to the application of such exemption thereto. The foregoing restriction shall not apply to (i) issuances by the Company so long as the Shares being issued are registered under the Securities Act and a prospectus in respect thereof is current or (ii) re-offerings of Shares by affiliates of the Company (as defined in Rule 405 or any successor rule or regulation promulgated under the Securities Act) if the Shares being re-offered are registered under the Securities Act and a prospectus in respect thereof is current. 14. ISSUE OF CERTIFICATES, LEGENDS, PAYMENT OF EXPENSES Subject to Articles 13, 15 and 16, upon any exercise of an Option which may be granted hereunder and payment of the purchase price, a certificate or certificates for the Shares shall be issued by the Company in the name of the person exercising the Option and shall be delivered to or upon the order of such person. The Company may endorse such legend or legends upon the certificates for Shares issued pursuant to the Plan and, if a transfer agent has been engaged by the Company, may issue such "stop transfer" instructions to its transfer agent in respect of such Shares as, in its discretion, it determines to be necessary or appropriate to (i) prevent a violation of, or to perfect an exemption from, the registration requirements of the Securities Act, or (ii) implement the provisions of the Plan and any agreement between the Company and the Optionholder with respect to such Shares, or (iii) permit the Company to determine the occurrence of a disqualifying disposition, as described in Section 421(b) of the Code, of Shares transferred upon exercise of an Incentive Option granted under the Plan. The Company shall pay all issue or transfer taxes with respect to the issuance or transfer of Shares, as well as all fees and expenses necessarily incurred by the Company in connection with such issuance or transfer. All Shares issued as provided herein shall be fully paid and non-assessable to the extent permitted by law. 15. WITHHOLDING TAXES The Company will require, as a condition to an Optionholder exercising an Option granted hereunder, that the Optionholder reimburse the corporation that employs such Optionholder for any taxes required by any government to be withheld or otherwise deducted and paid by such corporation in respect of the issuance or disposition of such Shares. In lieu thereof, the corporation that employs such Optionholder shall have the right to withhold the amount of such taxes from any other sums due or to become due from such corporation to the Optionholder upon such terms and conditions as the Committee shall prescribe. The corporation that employs such Optionholder may, in its discretion, hold the stock certificate to which such Optionholder is entitled upon the exercise of an Option as security for the payment of such withholding tax liability, until cash sufficient to pay that liability has been accumulated. 16. LISTING OF SHARES AND RELATED MATTERS The Committee may delay the issuance or delivery of Shares pursuant to any Option granted hereunder if it determines that listing, registration or qualification of Shares or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the grant of an Option under the Plan or the issuance of Shares thereunder, until such listing, registration, qualification, consent or approval shall have been effected or obtained, or otherwise provided for, free of any conditions not acceptable to the Committee. 17. AMENDMENT OF THE PLAN The Committee may, from time to time, amend the Plan, provided that no amendment shall be made, without the approval of the stockholders of the Company, that will (i) increase the total number of Shares reserved for Options under the Plan or the amount of Options that may be granted to any key employee (in each case, other than an increase resulting from an adjustment provided for in Article 11), (ii) reduce the exercise price of any Option granted hereunder below the price required by Article 5, (iii) modify the provisions of the Plan relating to eligibility, or (iv) materially increase the benefits accruing to participants under the Plan. The rights and obligations under any Option granted before amendment of the Plan or any unexercised portion of such Option shall not be adversely affected by amendment of the Plan or such Option without the consent of the holder of such Option. 18. TERMINATION OR SUSPENSION OF THE PLAN The Board of Directors may at any time suspend or terminate the Plan. The Plan, unless sooner terminated by action of the Board of Directors, shall terminate at the close of business on the Termination Date. Options may not be granted while the Plan is suspended or after it is terminated. Rights and obligations under any Option granted while the Plan is in effect shall not be altered or impaired by suspension or termination of the Plan, except upon the consent of the person to whom the Option was granted. The power of the Committee to construe and administer any Options granted prior to the termination or suspension of the Plan under Article 3 nevertheless shall continue after such termination or during such suspension. 19. GOVERNING LAW The Plan and such Options as may be granted thereunder and all related matters shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware from time to time obtaining. 20. PARTIAL INVALIDITY The invalidity or illegibility of any provision hereof shall not be deemed to affect the validity of any other provision. 21. EFFECTIVE DATE The Plan shall become effective at 9:00 a.m., New York City Time, on the Effective Date, provided the Plan is approved by the stockholders of the Company at an annual meeting or any special meeting of stockholders of the Company within 12 months of the Effective Date, and such approval of stockholders shall be a condition to the right of each eligible key employee to receive any Options under the Plan. Any Options granted under the Plan prior to such approval of stockholders shall be effective as of the date of the grant (unless, with respect to any Option, the Committee specifies otherwise at the time of the grant), but no such Option may be exercised prior to such stockholder approval, and if stockholders fail to approve the Plan as specified hereunder, any such Option shall be cancelled.
