          (ii)  any failure by the Company to comply with any of the

                              CONSULTING AGREEMENT

         This Consulting Agreement (this "Agreement") is entered into as of this
1st day of SEPTEMBER, 2004 by and between CTI MOLECULAR IMAGING, INC. ("CTI"), a
Delaware corporation, and THOMAS J. HOOK ("Hook"), a resident of Knoxville,
Tennessee.

                                   WITNESSETH:

         WHEREAS, Hook is employed by CTI as President of P.E.T.Net
Pharmaceuticals, Inc., President of CTI Solutions Group and Corporate Vice
President of CTI pursuant to an employment contract entered into on July 19,
2002 (the "Contract"); and

         WHEREAS, Hook has elected to resign his employment with CTI because he
is more interested in the device and capital equipment business than in the
future bio-marker business anticipated of CTI, he has an important family need
to live in Buffalo, New York, and he believes he can continue to make the
maximum contribution to CTI by assuming a strategic advisory role in the
Company; and

         WHEREAS, CTI accepts Hook's resignation; and

         WHEREAS, the directors of CTI would like to recognize the high level of
contributions of Hook to CTI by offering him a severance package and placing him
in a strategic consulting role.

         NOW, THEREFORE, in consideration of the severance payments and other
benefits as set forth herein, the mutual covenants and premises herein contained
and for other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the parties hereto agree as follows:

         1.     RESIGNATION. Hook hereby resigns his employment with CTI and as
President of P.E.T.Net Pharmaceuticals, Inc., President of CTI Solutions Group
and Corporate Vice President of CTI, effective September 1, 2004. The Contract
is hereby terminated and Hook forfeits all rights and benefits pursuant to the
Contract, unless expressly provided to the contrary in this Agreement.

         2.     SEVERANCE PAYMENT. In consideration of the release of claims and
other promises by Hook as set forth herein, CTI will pay Hook One Hundred Fifty
Thousand Dollars ($150,000.00), less all applicable withholdings, on October 1,
2004 as severance pay. This $150,000.00 includes all accrued unused paid time
off and vacation to which Hook may be entitled. CTI will also continue to pay
for Hook's health insurance, under the same terms and conditions that applied on
September 1, 2004, through September 30, 2004. After September 30, 2004, Hook
will have the right to continue his health insurance under the CTI health
insurance plan pursuant to the applicable COBRA requirements. In addition, CTI
will continue to pay for Hook's apartment in Knoxville and the storage of his
personal property in Knoxville until October 1, 2004. The compensation and
benefits set forth in this paragraph represent complete and final payment to
Hook for his services as an employee of CTI, and Hook agrees that he is not
entitled to any further payments or benefits from CTI as a result of his
employment (non-consultant) relationship.

                                       1
<PAGE>

         3.     CONSULTING ROLE. Effective September 1, 2004, Hook will serve as
Strategic Advisor to the President and CEO of CTI. Hook will remain in this
capacity from September 1, 2004 until September 1, 2006, unless either party
terminates the relationship pursuant to written notice sent thirty (30) days in
advance of the date of termination. As Strategic Advisor, Hook will work a
minimum of twenty-five (25) hours per month for CTI. Throughout his service as
Strategic Advisor, Hook will provide his best efforts to CTI and will publicly
and privately provide positive support to CTI and its officers and directors.

         Hook's initial work plan as Strategic Advisor shall include, but may
not be limited to, the following tasks:

         a.       Continue to participate on Company two strategic plans;

         b.       Finalize CTI Solutions' budget for fiscal year 2005; and

         c.       Prepare a retention plan for Joe Sardano, Tom Welch, Joan
Washburn and Chris Behrenbruch.

The work plan will be redefined quarterly based on a review between the
President and CEO of CTI and Hook. Additionally, Hook will perform such other
tasks as Strategic Advisor as may be assigned to him from time to time by the
President and CEO of CTI. The parties agree that, by serving in this capacity,
Hook will be providing substantial services to CTI.

         4.     COMPENSATION. As Strategic Advisor, Hook will be paid the amount
of Twenty-Five Thousand Dollars ($25,000.00) in a lump sum at the end of each
quarter. In the event either party terminates the Agreement prior to the
expiration of a quarter, Hook's compensation will be reduced on a pro-rata basis
for that quarter. All payments sent to Hook pursuant to this Agreement will be
sent to Hook's address as provided herein. Except for reasonable expenses that
may be incurred pursuant to paragraph 14 herein, the compensation described in
this paragraph includes all amounts to be paid by CTI to Hook for his work as
Strategic Advisor, and Hook shall not be entitled to any other payments from
CTI. CTI will reimburse Tom Hook for any reasonable expenses associated with his
consulting.

         5.     STATUS AS INDEPENDENT CONTRACTOR. While serving CTI as Strategic
Advisor, Hook will be an independent contractor. As such, Hook will not be
considered an employee of CTI for federal tax purposes or any other purposes.
CTI shall not deduct withholding taxes, FICA or any taxes required to be
deducted by an employer, and Hook agrees that he shall be responsible to pay any
and all such taxes as an independent contractor. CTI will have no obligations
with respect to Hook that it might otherwise have at law with respect to regular
employees. Hook will not be entitled, among other things, to share in employee
benefits available for regular employees of CTI, including but not limited to,
fringe benefits, pension, retirement, profit-sharing, bonus plans, unemployment
benefits or workers' compensation. CTI agrees to record Hook's annual earnings
at the end of the year on an Internal Revenue Service Form 1099. A copy of the
Form 1099 will be provided to the Internal Revenue Service and to Hook.

         6.     STOCK OPTIONS. Effective September 1, 2004, Hook will forfeit
all vested and unvested unrestricted stock options that have not yet been
exercised. Hook will retain the

                                       2
<PAGE>

unvested portion of the restricted stock granted to him in the Contract.
One-half of these unvested restricted shares will vest on September 1, 2005 and
the other half will vest on September 1, 2006, provided that Hook has fully and
completely complied with the first two years of the covenant not to compete set
forth in paragraph 12 herein. If Hook violates any aspect of the covenant not to
compete, Hook will forfeit all remaining unvested restricted shares of stock.
Hook hereby forfeits, waives and releases his right to the cash bonus guarantee
for restricted stock as set forth in the Contract. The parties hereby
acknowledge and agree that this covenant not to compete constitutes a
substantial risk of forfeiture of unvested restricted stock because of, among
other factors, Hook's age, 41; the availability of alternative employment
opportunities for Hook; the likelihood of Hook obtaining other employment; the
degree of skill possessed by Hook and Hook's health.

         7.     RELEASE OF ALL CLAIMS AND POTENTIAL CLAIMS AND COVENANT NOT TO
SUE. In consideration of the severance payment and all other benefits, covenants
and promises contained in this Agreement, Hook, on behalf of himself and his
agents, personal representatives, heirs, successors and assigns, hereby
UNCONDITIONALLY RELEASES AND FOREVER DISCHARGES CTI, and its successors,
subsidiaries, parent corporations, affiliates, divisions, agents, legal
representatives, attorneys, employees, officers, directors, insurers, successors
and assigns, individually and in their representative capacities, together with
their successors and assigns (hereinafter collectively referred to as "CTI")
from and against any and all claims, demands, damages, liabilities and causes of
action of every kind or character, whether known or unknown, fixed or
contingent, legal or equitable, that Hook may have or claim to have against CTI
for any reason, including, without limitation, those past, present and future,
accruing or accrued at any time prior to the date of the signing of this
Agreement, and

         a.     any and all claims arising from Hook's employment with, or

agreements, bonus plans, incentive pay plans and any other agreement entered

reasonable and properly documented expenses that Hook may incur in providing the
requested assistance.

         15.    NON-WAIVER. The failure by either party to exercise any of its

prevent either party from later enforcing strict compliance with this Agreement
as to such breach or any subsequent breach.

no term or provision of this Agreement is to be interpreted as waiving or

         17.    SEVERABILITY. If any provision of this Agreement is held by a
court of competent jurisdiction to be void or unenforceable for any reason, such
