THIS AGREEMENT (this
Agreement) is made and entered into as of this 30thday of October 2006 (the Effective
Date), by and between Optical Molecular Imaging, Inc., a Delaware corporation (the Company), and David Wohlberg (Wohlberg).

WHEREAS, the Company and Wohlberg desire to enter into a relationship whereby the Company will continue to engage Wohlberg, and Wohlberg will provide services as the President and Chief Operating Officer of the
Company pursuant to the terms and provisions contained herein;

NOW, THEREFORE, in consideration of the mutual promises set forth herein,
the Company and Wohlberg hereby agree as follows:

1. Services. Wohlberg agrees to continue to provide to the Company services in
the capacity of the Companys President and Chief Operating Officer (the Services). The Services will be those customarily performed by a president and chief operating officer for a company such as the Company, and Wohlberg shall be
responsible for the day-to-day management of the Company and the implementation of all policies and directives of the Companys Board of Directors. Wohlberg will report directly to and be responsible to the Companys Chairman of the Board
or, if there is no Chairman, to the Companys Board of Directors. Wohlberg will perform the Services primarily at the Companys office, and, if required in particular circumstances, from time to time at such other locations as the Board of
Directors may reasonably request. Wohlberg shall perform the Services on a part-time basis during the Companys normal business hours, spending a majority of his business time on the Companys business.

2. Term. The term of this Agreement shall commence as of October 30, 2006 and shall terminate on October 29, 2007, unless sooner
terminated by Wohlberg or the Company as set forth in Section 8 hereof.

3. Compensation.

3.1 Compensation. As payment in full for Wohlbergs services as the Companys President and Chief Operating Officer for the period from
May 1, 2006 through October 29, 2006, the Company shall grant to Wohlberg fully vested stock options (the Interim Options) to purchase 90,000 shares of the Companys common stock and pay to Wohlberg salary of $2,000 per
month, all payable within 15 days of the execution of this Agreement. As payment in full for the Services during the term of this Agreement, the Company shall grant to Wohlberg options to purchase 95,000 shares of the Companys common stock
(the New Options), which shall vest quarterly over the one-year term of this Agreement, and a salary of $2,000 per month, which shall increase to $2,500 per month immediately upon the Company signing the definitive License Agreement with
Cedars-Sinai Medical Center. Cash compensation shall be paid monthly on the last business day of each month. The Interim Options and the New Options will have a seven-year term, commencing on the date of grant; an exercise price of $1.00 per share;
will be exercisable within the term

of those options during the period that Wohlberg provides services to the Company and for 24 months after termination for any reason except termination for
cause by the Company; and will have such other terms and conditions as are included in the Companys standard Stock Option Agreement under its Stock Option Plan. All options previously granted to Wohlberg shall also be amended to provide for
exercisability of those options within the term of those options during the period that Wohlberg provides services to the Company and for 24 months after termination of those services for any reason other than termination for cause by the Company.

3.2 Cash Payments. While this Agreement is in effect, the Company will make all cash payments on the last business day of each
month.

4. Outside Activities; Corporate Opportunity. The Company hereby acknowledges that Wohlberg is an attorney, licensed to
practice law in the State of California, and is of counsel for Troy & Gould Professional Corporation. As such, he provides legal services and business advice to companies and individuals other than the Company. Wohlberg may
continue to perform such services for others, and such performance shall not be deemed to constitute a usurpation of a corporate opportunity of the Company or a breach of Wohlbergs obligations hereunder; provided, however, that
such activities do not materially impair his ability to perform all of his duties under this Agreement and do not relate directly to products or potential products based on immunocellular technologies for medical purposes. The Company shall neither
request nor will Wohlberg under any circumstances provide legal advice or legal services for the Company.

5. Proprietary Rights.
All inventions, improvements, discoveries, copyrightable or patentable works, intellectual property, whether or not patentable or copyrightable, and all other work performed and all materials developed or prepared by Wohlberg, within the scope of
his engagement by the Company, whether developed or prepared solely or jointly by Wohlberg with others, are the property of the Company and all rights, title and interest therein shall vest in the Company and shall be deemed to be works made for
hire and made in the course of the services rendered hereunder. To the extent that title to any such works may not, by operation of law, vest in the Company or such works may not be considered works made for hire, all rights, title and interest
therein are hereby irrevocably assigned to the Company. All such materials shall belong exclusively to the Company, and the Company shall have the right to obtain and to hold in its own name, copyrights, trademarks, patents, other registrations, or
such other protection as may be appropriate to the subject matter, and any extensions and renewals thereof. Wohlberg agrees to give the Company and any person designated by the Company such reasonable assistance, at the Companys expense, as is
required to perfect the rights defined in this Section 5. Wohlberg agrees to return to the Company all materials developed or prepared for the Company by Wohlberg upon the termination of this Agreement, along with all materials and other
