Mr. Tom Hook
2710 Wynfield Lane
Brookfield, Wisconsin 53045

Dear Tom:

The following is an update to our previous offers of employment dated July 16,
2002 and July 18, 2002 and supersedes all prior offers and discussions.

We are very pleased to offer you employment as the President of CTI Services,
Inc. (You may want to change the name of CTI Services to be more descriptive.)
and Senior Vice President of CTI Molecular Imaging, Inc (CTI), the parent
company of CTI Services. In this position, you will report to the CTI Chairman
and CEO and serve with the Senior Leadership Team (SLT) of CTI in providing the
strategic and operational leadership for CTI and the CTI companies. Other
members of the CTI SLT include Ron Nutt, the President of CTI PET Systems, Inc.
(CPS), Mark Rhoads, the President of PETNet Pharmaceuticals, Inc. (PETNet),
David Gill, Chief Financial Officer and CTI Senior Vice President, Mike Phelps,
CTI Director, and Terry Douglass, Chairman and CEO of CTI. The Effective Date
of your employment will be July 22, 2002.

As discussed, your direct responsibilities and reports initially will include
the CTI Distribution Company (which provides marketing, sales, and service for
the CPS ECAT scanner products, CTI RDS cyclotron, and CTI PowerSolutions
products), the CTI Sources business, CTI Service Solutions, and CTI, GmbH. In
the near future, you may want to also pick up direct responsibility for CTI
Cyclotron Systems (which develops and manufactures our RDS cyclotron and
chemistry production systems), ACT, Inc. (which produces BGO), and CTI Detector
Materials (which develops and produces LSO). You will also be the CTI Officer
responsible for our new investment and operational initiatives with the PET and
PET/CT provider community.

We believe you have the background, skills, and energy to make a significant
contribution to our long-term success, and that you will play an important role
in helping CTI achieve our goals and objectives. We also believe that CTI
provides a unique environment and career challenges that will stimulate your
continued personal

<PAGE>
and professional development and that will provide significant financial rewards
as we are successful in the implementation of our mission and strategies.

Subject to the approval of the CTI Board of Directors, we are offering you a
comprehensive compensation package which includes the following elements:

- Base salary of $250,000 a year, paid every two weeks. Your salary will be
  reviewed annually by the Board of Directors of CTI.

- A professional expense and car allowance of $12,000 per year, paid every two
  weeks.

- Participation in the executive incentive pay program. Basically, you can earn
  up to 150% of your base salary in incentive pay compensation. For a "normal"
  year, e.g. one in which we make plan, you could earn a cash bonus of 50% of
  base pay for the year. For a "very good" year, you could earn up to an
  additional 50% of base pay with 50% of the amount in cash and 50% in stock
  options. For an "outstanding" year, you could earn up to an additional 50% of
  base pay all of which would be in stock options. The number of shares in the
  options would be determined from the dollar amount of the applicable bonus and
  the FMV of the stock at the time of the award. The parameters defining a
  normal, very good, and outstanding year will be defined at the beginning of
  the year by the Officer Compensation Committee of the Board.

- An Incentive Stock Option grant of 600,000 CTI shares* at the CTI closing
  price of the stock on the Effective Date of your employment with CTI. (*These
  will be incentive stock options to the extent permitted by law. The remainder
  will be non-qualified options.) Twenty-five percent of the options would vest
  on your start date and 25% would vest on each anniversary of your start date.
  Obviously, the potential for significant returns from the growth in value of
  CTI is very high, and you will be a major contributor to making that happen.

- A Restricted Stock grant equal to the number of CTI shares that would be
  equivalent in value to $2,000,000 at the CTI closing price on the Effective
  Date of your employment with CTI. These shares will vest subject to your
  continued employment with CTI at a rate of 25% per year commencing on the
  first anniversary of your Effective Date of employment. On the four successive
  anniversary dates of your Effective Date of employment with CTI, if the
  closing price of CTI stock is less than the closing price on the Effective
  Date of your employment, you will receive a cash bonus equal to the difference
  between $500,000 and the value of the restricted shares that vest on such
  anniversary.

<PAGE>
-        A loan option from CTI not to exceed $2,000,000. We agree that we will
         allow you to borrow funds from CTI at market rates up to an amount not
         to exceed $2,000,000 in principal value. The company's obligation to
         make this loan is expressly subject to your demonstrated financial
         ability to repay the obligation on the date of grant and throughout the
         period that the loan remains outstanding. Any loan from the company
         will be secured by a pledge of the restricted stock award and will be a
         recourse obligation.

-        An excellent Fringe Benefits Program, which includes a medical and
         dental plan, life insurance, and a 401(k) Plan. The CTI Benefits
         Program provides a number of individual options, including the
         opportunity to achieve tax savings through Flexible Spending and
         Dependent Care Accounts. We have provided some additional information
         that will help to quantify the value of your personal CTI benefits
         package.

-        Three weeks of vacation per year and ten paid holidays.

-        A relocation package which includes the relocation of your household
         goods with our current carrier, Kwick-Way Transportation, temporary
         housing and storage for up to twelve months with Corporate Quarters,
         and reimbursement of the following items relating to your relocation:

         -        Closing costs on the sell of your current home, including
                  realtor fees

         -        Closing costs on the purchase of a new home in Knoxville
                  including realtor fees if purchased within 18 months of your
                  CTI hire date

         -        House hunting trip to Knoxville

         -        Travel expenses to Knoxville to begin employment

         -        Travel expenses to Wisconsin to close on current home

         -        Fees for driver's license fee, car registration, and utility
                  connections if done within 18 months of your CTI hire date

         -        If your home doesn't sell within 12 months, we will provide
                  duplicate housing (lesser of your two payments) for an
                  additional 6 months

         -        A relocation allowance of $50,000 to cover other transition
                  expenses and to cover IRS taxes on the relocation package.

Much of the cost of the relocation is considered income to you and must be
reported to the IRS and state taxing authorities. Only shipping of your
household goods and autos, storage of your household goods for 30 days, and
final moving expenses (except meals) are excludable or adjustable from income.
Should you voluntarily leave CTI prior to 12 months from your hire date, you
must reimburse CTI for the total cost of relocation.

This offer is contingent on your ability to pass a drug screening test
administered by a licensed physician designated by and compensated by CTI. This
offer is also
<PAGE>
contingent on your agreement to CTI's "Guidelines for Protection of
Confidential and Proprietary Information" which is attached. You should sign
and return these guidelines to us with the signed copy of the offer letter.

In the event that, CTI terminates your employment for any reason other than
Cause or disability, then you shall be entitled to receive the following
payment: CTI shall pay you following the date of your employment termination
and over the succeeding six (6) months, in accordance with standard payroll
procedures, an amount equal to six (6) months of your base salary in effect on
the date of the employment termination.

CTI may terminate your employment for "Cause." "Cause" will exist in the event
you are convicted of a felony, or in carrying out your duties, you are guilty
of gross negligence or gross misconduct resulting, in either case in material
harm to CTI. In the event your employment is terminated for Cause or
disability, you will be entitled to any unpaid salary through the date of
termination due you, and you will be entitled to no other compensation
hereunder from CTI and your deferred compensation will be forfeited.

We want you to know how much we hope that you decide to join us. If you have
any questions or we can assist you in any way, please let us know.


Regards,


     /s/ Terry Douglass                                /s/ Traci Etherton
