The Option shall become exercisable to purchase, and shall vest with respect to, that number of Option Shares as provided in the Vesting Schedule provided below. PARTICIPANT: MICHAEL A. CARENZO DATE OF GRANT: April 23, 1996 NUMBER OF SHARES PURCHASABLE: 900,000 EXERCISE PRICE PER SHARE: $2.30 EXPIRATION DATE: April 22, 2001 VESTING SCHEDULE: A total of 50,000 Option Shares shall vest and become exercisable on the date Participant is appointed or elected a Director of the Company, an additional 40,000 Options Shares shall vest and become exercisable on the date of commencement of Participant's employment as President and CEO of the Company. The balance of the Options Shares shall vest monthly, at month end, commencing July 31, 1996 at the rate of 22,500 Option Shares per month, conditioned on Participant's continued Employment. In the event the closing price of the Common Stock exceeds five dollars ($5.00) per share for ten consecutive trading days at any time prior to December 31, 1997, then 50% of any unvested options shall vest with the balance vesting in equal installments monthly over the balance of the 36 month vesting term.

The Board of Directors or the Committee may accelerate the vesting of options at its discretion. IRRESPECTIVE OF THE VESTING SCHEDULE ABOVE OR THE TERMS HEREIN, THE OPTION MAY NOT BE EXERCISED BEFORE THE APPROVAL OF THE PLAN BY THE SHAREHOLDERS OF THE COMPANY ON OR BEFORE THE EXPIRATION OF TWELVE MONTHS FROM THE DATE OF ADOPTION OF THE PLAN BY THE BOARD OF DIRECTORS AND IF SUCH APPROVAL IS NOT OBTAINED THEN THIS OPTION SHALL BE VOID.

The balance of this Option and any Option Shares determined not to qualify are not intended to be treated as an incentive stock option under Section 422 of the Internal Revenue Code (an "Incentive Stock Option") and shall be non-qualified ("Nonqualified Stock Option"). 2.

All notices and other communications required or permitted to be given pursuant to this Agreement shall be in writing and shall be deemed given if delivered personally or five days after mailing by certified or registered mail, postage prepaid, return receipt requested, to the Company at 12875 Brookprinter Place, Suite #300, Poway, California 92064, Attention: Robert Putnam, or to Participant at the address set forth beneath his or her signature on the signature page hereto, or at such other addresses as they may designate by written notice in the manner aforesaid. 8. APPLICABLE LAWS. Notwithstanding anything to the contrary in this Agreement, no shares of stock purchased upon exercise of the Option, and no certificate representing all or any part of such shares, shall be issued or delivered if in the opinion of counsel to the Company, such issuance or delivery would cause the Company to be in violation of or to incur liability under any federal, state or other securities law, or any requirement of any stock exchange listing agreement to which the Company is a party, or any other requirement of law or of any administrative or regulatory body having jurisdiction over the Company. The issuance of any unregistered Shares upon the exercise of an Option shall be conditioned upon the Participant providing to the Committee a written representation that, at the time of exercise, it is the intent of the Participant to acquire the Shares for investment only and not with a view toward distribution. Any unregistered Shares shall be restricted as to transfer by the Company unless the Company receives an opinion of counsel satisfactory to the Company to the effect that such restriction is not necessary. 9. NONTRANSFERABILITY. Neither the Option nor any interest therein may be sold, assigned, conveyed, gifted, pledged, hypothecated or otherwise transferred in any manner other than by will or the laws of descent and distribution. 10. PLAN. The Option is granted pursuant to the Plan, as in effect on the Date of Grant, and is subject to all the terms and conditions of the Plan, as the same may be amended from time to time; provided, however, that no such amendment shall deprive Participant, without his or her consent, of the Option or of any of Participant's rights under this Agreement. The interpretation and construction by the Committee of the Plan, this Agreement, the Option and such rules and regulations as may be adopted by the Committee for the purpose of administering the Plan shall be final and binding upon Participant. Until the Option shall expire, terminate or be exercised in full, the Company shall, upon written request therefor, send a copy of the Plan, in its then-current form, to Participant or any other person or entity then entitled to exercise the Option. 11. SHAREHOLDER RIGHTS. No person or entity shall be entitled to vote, receive dividends or be deemed for any purpose the holder of any Option Shares until the Option shall have been duly exercised to purchase such Option Shares in accordance with the provisions of this Agreement. 12. UNEMPLOYMENT OR CONTRACT RIGHTS. No provision of this Agreement or of the Option granted hereunder shall (a) confer upon Participant any right to continue in the employ of or contract with the Company or any of its subsidiaries, (b) affect the right of the Company and each of its subsidiaries to terminate the employment or contract of Participant, with or without cause, or (c) confer upon Participant any right to participate in any employee welfare or benefit plan or other program of the Company or any of its subsidiaries other than the Plan. PARTICIPANT HEREBY ACKNOWLEDGES AND AGREES THAT THE COMPANY AND EACH OF ITS SUBSIDIARIES MAY TERMINATE THE EMPLOYMENT OR CONTRACT OF PARTICIPANT AT ANY TIME AND FOR ANY REASON, OR FOR NO REASON, UNLESS PARTICIPANT AND THE COMPANY OR SUCH SUBSIDIARY ARE PARTY TO A WRITTEN EMPLOYMENT, CONSULTING OR OTHER AGREEMENT THAT EXPRESSLY PROVIDES OTHERWISE. 13. SURVIVORSHIP. The respective rights and obligations of the Parties hereunder shall survive any termination of this Agreement to the extent necessary to the intended preservation of such rights and obligations. 14. CONFLICTS. If there are any conflicts between the terms and conditions of this Agreement and the terms and conditions of any Employment Agreement with the Participant, then the terms and conditions of the Employment Agreement shall govern. 15. SEVERABILITY. In the event that any provision or portion of this Agreement shall be determined to be invalid or unenforceable for any reason, in whole or in part, the remaining provisions of this Agreement shall be unaffected thereby and shall remain in full force and effect to the fullest extent permitted by law. 9 11 16. GOVERNING LAW.
