                              W I T N E S S E T H :
                              ---------------------

         WHEREAS, the Company, through its wholly owned subsidiary, Premier
P.E.T. Imaging International, Inc. ("Premier") owns, operates and/or manages
several outpatient medical diagnostic imaging centers in New York, New Jersey,
Kansas and Florida (the "PET Centers") and intends to acquire or open additional
diagnostic imaging centers throughout the United States (the "Additional PET
Centers"), including diagnostic imaging centers in the State of Florida (the
"New Florida Centers"); and

         WHEREAS, the PET Centers utilize positron emission tomography ("PET")
or PET/computed tomography ("CT") imaging scanners, and the Company contemplates
that the Additional PET Centers (including the contemplated New Florida
Centers), will also utilize PET or PET/CT imaging scanners; and

         WHEREAS, Radiologist has special expertise in radiology and nuclear
medicine and has been and is currently engaged in rendering reading and
interpretative radiological vices with respect to diagnostic imaging scans
produced by a variety of medical diagnostic imaging equipment, including PET and
PET/CT imaging scanners; and

         WHEREAS, the Company is desirous of engaging the services of
Radiologist to perform radiology and related professional services for the New
Florida Centers, and certain of the PET Centers and Additional PET Centers, and
Radiologist is willing to be engaged to perform such services, all on and
subject to the terms and conditions hereinafter set forth.

         NOW, THEREFORE, in consideration of the mutual covenants herein and
other good and valuable consideration, the parties hereto do hereby agree as
follows:

                                    ARTICLE 1
                            RETENTION OF RADIOLOGIST
                            ------------------------

         1.1.     During the Term (hereinafter defined) of this Agreement and
subject to the terms and conditions hereof (including the non-compete
restrictions referred to in Section 11.4 hereof), the Company hereby retains
Radiologist, and Radiologist hereby agrees to such retention, to perform all

                                      -1-
<PAGE>

Services (hereinafter defined) for all New Florida Centers, and any of the PET
Centers and/or Additional PET Centers as may be designated by the Company from
time to time during the Term of this Agreement (all such imaging centers for
which Radiologist will perform Services under this Agreement are referred to
herein as the "Covered PET Centers"). Radiologist will render all radiology
services (i.e., reading and interpreting all PET, CT, PET/CT, or other imaging
modality scans), exclusively for the Company during the Term of this Agreement,
will devote such portion of his business time, effort and attention as is
necessary to perform the Services provided for under this Agreement and will not
render any such radiology services to any third party during the Term of this
Agreement (except as provided in Section 1.3 below).

         1.2.     During the period that the restrictive covenant contained in
that certain Professional Services Agreement dated as of October 22, 2002
between National PET Management Scan, L.L.C. ("National PET") and Radiologist
remains in force and effect and binding upon Radiologist, Radiologist will
select (subject to the Company's approval), train and supervise another
qualified radiologist to read and interpret all PET and/or PET/CT scans that are
performed at any New Florida Center which is located within the geographical
area covered by such restrictive covenant. Radiologist will notify the Company,
in writing, of the date on which the aforementioned restrictive covenant is no
longer in force and effect and binding upon Radiologist.

         1.3.     Consistent with the exclusivity provisions contained in
Section 1.1 hereof, Radiologist will, on the date hereof, provide a
one-hundred-eighty (180) day notice to RCOA of the termination of that certain
Professional Services Agreement dated as of May 1, 2005 between Advanced
Diagnostic Imaging Professional Services, P.L.L.C. ("ADIP") and RCOA (the "RCOA
Professional Services Agreement") (and will provide a copy of such notice to the
Company). Radiologist will use his best efforts to hire, train and supervise
another radiologist to perform and render all services required of ADIP under
the RCOA Professional Services Agreement, and will discontinue, as soon as
possible after the date hereof (but not later than sixty (60) days from the date
hereof), providing any radiology services to ADIP pursuant to the RCOA
Professional Services Agreement. Radiologist will notify the Company when he
discontinues reading and interpreting imaging scans, as aforesaid.
Notwithstanding the foregoing, Radiologist will discontinue all such radiology,
training and supervisory services to ADIP upon the earlier of the end of the
term of the RCOA Professional Services Agreement, or the date on which the
restrictive covenant by which Radiologist is bound under the RCOA Agreement is
no longer in force and effect (the "RCOA Termination Date"). Furthermore,
notwithstanding the foregoing, Radiologist will cause ADIP to provide notice to
RCOA Florida of any breach or default of RCOA Florida under the RCOA
Professional Services Agreement upon the occurrence thereof (and will provide a
copy of such notice to the Company) and, if any such breach or default is not
cured by RCOA Florida pursuant to the terms of such agreement, Radiologist will
cause ADIP to terminate the RCOA Professional Services Agreement (and will
advise the Company of the date of any such termination).

         1.4.     In consideration of the time and effort you will be required
to expend in connection with the training and supervising activities provided
for in Section 1.3 hereof, the Company will pay to you a fee of $100 for each
imaging scan read and interpreted by the other radiologist referred to in
Section 1.3 (the "Training Fee"), for so long as such other radiologist reads
and interprets such imaging scans, which Training Fee will be payable to you
monthly, within 15 days after the end of each month during the Term hereof,
subject to Radiologist providing the Company with a report of all such imaging
scans read and interpreted by such other radiologist on or before the fifth day
of the month immediately following the month in which such imaging scans were
read and interpreted by such other radiologist. Radiologist will notify the
Company, in writing, upon the occurrence of the RCOA Termination Date.

Company's request).

         2.3.     Radiologist will read and interpret all Imaging Scans from
Radiologist's Florida residence or, upon the Company's request, from any
facility hereafter acquired or established by it which is located in Broward or
Palm Beach County, Florida and will not be required to be present on site
outside of Florida for such purposes.

         2.4.     Radiologist will be available to the Company to respond to
questions and inquiries pertaining to all Imaging Scans and Radiologist's
reports with respect thereto and will consult with the Company and make
recommendations with respect to the operating procedures and protocols in regard

         2.5.     At all times during the Term hereof, Radiologist will
maintain, at his expense, all medical and other licenses and certifications
required to perform the Services, including such licenses and certifications as

Radiologist will not have any authority to bind or otherwise obligate the
Company (or Premier or any other subsidiary of the Company or any entity which
owns, operates or manages any of the Covered PET Centers) and will be solely
responsible for all withholding, income, unemployment insurance, social security
and other like Federal and state taxes with respect to the compensation paid to
the Radiologist by the Company under this Agreement.

aforementioned bills will be the sole and exclusive property of the Company (or
such entity) and Radiologist will execute and deliver to the Company all forms

the Company (or such entity) to collect such payments or other revenues. In the

Services are received by Radiologist (or any entity with which Radiologist is

entity), together with back-up documentation with respect thereto.

         3.2.     Radiologist is a participant in various third party payment
plans and programs including, without limitation, Medicare, Medicaid, health
maintenance organizations and preferred provider organizations. Radiologist

the Company, and the entity that is conducting its medical practice at the
Covered PET Center, or which otherwise owns, operates or manages any such

                                      -4-

                                  COMPENSATION
                                  ------------

         6.1.     In consideration of the performance of Radiologist's Services
under this Agreement, the Company will pay Radiologist a fee of Two Hundred
Fifty Thousand Dollars ($250,000) in each year of the Term hereof (the "Annual
Fee"), such fee being payable to Radiologist in equal monthly installments, in
arrears. The first and last monthly installments of the Annual Fee shall be
prorated based upon the number of days in each of such months (and the prorated
Annual Fee for October 2005 in the amount of $6,164.38 will be paid to
Radiologist on or before November 1, 2005).

         6.2.     In addition to the Annual Fee, the Company will pay
Radiologist a fee of $170 for each Imaging Scan read and interpreted by
Radiologist in each year of the Term hereof in excess of the Threshold Amount
(the "Additional Fee"). For purposes of this Agreement, the term "Threshold
Amount" shall mean 1,470 PET scans. If, however, the total number of PET scans
read and interpreted by Radiologist in each such year is less than 1,470 (the
"Shortfall"), the Shortfall will be reduced by (i) calculating the difference
between $250,000 and an amount equal to the number of PET scans read and
interpreted by Radiologist during that period multiplied by $170 (the
"Deficiency") and (ii) reducing the Deficiency an amount equal to the number of
body part CT scans read and interpreted by Radiologist in such year multiplied
by $75 per body part CT scan, until the Deficiency is eliminated (at which time
the Threshold Amount will be achieved). At such time as the Threshold Amount has
been achieved, Radiologist will receive, as part of the Additional Fee, an
amount equal to $75 for each body part CT scan read and interpreted by
Radiologist in each such year of the Term hereof in excess of those body part CT
scans, if any, utilized in calculating the Threshold Amount, as aforesaid, (if
no such body part CT scans are utilized in so calculating the Threshold Amount,
Radiologist will receive payment, as part of the Additional Fee, in an amount
equal to $75 multiplied by all body part CT scans read and interpreted by
Radiologist in each such year).

         6.3.     The Additional Fee shall be payable to Radiologist within the
earlier of thirty (30) days after the end of each year during the Term hereof,
or within thirty (30) days after the Threshold Amount is reached, if such event
occurs prior to the end of any such year. If, however, the number of PET scans
read and interpreted by Radiologist for two successive quarters exceeds 367 PET
scans per quarter (and the Threshold Amount has not then been reached), the
Company will pay Radiologist an advance against the Additional Fee in an amount
equal to $170 times the number of such excess scans for the preceding quarter.
If, at the end of any such year, such advance(s) exceeds the Additional Fee
payable to Radiologist for such year, the amount of such excess will be deducted
from the Annual Fee payable to Radiologist in the following year. Radiologist
will provide the Company, within fifteen (15) business days after the end of
each month during the Term of this Agreement, with a report setting forth the
number of Imaging Scans read and interpreted by Radiologist in the prior month.

         6.4.     Upon the expiration or any earlier termination of this
Agreement (except for any such termination pursuant to Sections 4.3(c), (d), (e)
or (f) but, with respect to Section 4.3(f), only if such termination results
from a breach or default by Radiologist thereunder), and subject to the fee
advance provisions in Section 6.3 above. Radiologist shall be entitled to
receive the Additional Fee with respect to all Imaging Scans which have been
read and interpreted by Radiologist as of such date to the extent that the
number of such Imaging Scans exceeds the Threshold Amount as of such date. Any
such Additional Fee payable to Radiologist will be paid to Radiologist within
thirty (30) days after any such expiration or termination of this Agreement (and
any amount, if any, owed by Radiologist to the Company in the last year of the
Term hereof pursuant to the advance fee provisions of Section 6.3 above will be
paid to the Company by Radiologist within thirty (30) days after the end of the
Term hereof).

                                   ----------

         Each of the parties hereto shall have the right to inspect and copy the
books and records of the other pertaining to the compensation payable to
Radiologist hereunder and the number of Imaging Scans read and interpreted by
Radiologist hereunder upon reasonable prior notice and during normal business
hours. Any such inspection shall be conducted at the expense of the party
conducting any such inspection and all information and documentation obtained in
connection therewith will be subject to the confidentiality provisions contained
in Article 9 hereof.

                                   ---------

         For and in consideration of Radiologist's services hereunder, the
Company shall and hereby does agree to provide, at the Company's sole cost and
expense, professional and general liability insurance in the following minimum
coverage amounts and types. The Company shall provide professional liability
insurance coverage in the minimum coverage amounts of $1,000,000 per occurrence
and $3,000,000 in the aggregate (or such higher amounts as required by third
party payors and/or governmental entities with which the Company desires to
contract) with deductible limits customary and appropriate for the community
served by the Company and the Radiologist. Such insurance coverage will be in
the name of the Radiologist and, in the discretion of the Company, the Company
may purchase and acquire a separate binder that includes the Company as an
additional insured. Such professional malpractice insurance shall include 'full
prior acts coverage' in effect to the last day of Radiologist's employment with
the University of Florida School of Medicine, which is on or about June 30,
2000, or, in the Company's sole and exclusive discretion, the Company may
purchase one or more 'tail' policies to any and all professional malpractice
insurance policies in effect for or on behalf of Radiologist since the last day
of Radiologist's employment with the University of Florida School of Medicine.
Such professional malpractice coverage shall be continued throughout the Term of
this Agreement and shall be maintained by the Company for a period following the
expiration or termination of this Agreement, for any or no reason, equal to the
then applicable statute of limitations in the State of Florida; provided,
however, that the Company shall, in its sole and exclusive discretion, meet this

                                      -9-
<PAGE>

obligation by (a) maintaining this professional malpractice insurance coverage
following the termination or expiration of this Agreement for the then
applicable period of the statute of limitations, (b) the purchase of 'tail'
insurance if, at the time of the expiration or termination of the Agreement, the
Company has then purchased 'claims made' insurance on behalf of the Radiologist
or (c) the purchase of 'occurrences' based' insurance by and on behalf of the
Radiologist. Notwithstanding anything else contained herein to the contrary, the
parties acknowledge and agree that Radiologist's contract with National PET
dated October 22, 2002 and as amended by that First Amendment dated effective
January 1, 2004 requires, in Section 4.10 of that document, National to purchase
ongoing professional malpractice insurance following the termination of that
document effective as of October 22, 2005. Therefore, the Company shall be and
hereby is subrogated to any and all claims by Radiologist for such insurance to
the extent that Radiologist may transfer his rights thereunder. Finally, the
Company shall, during the Term of this Agreement, provide general liability
insurance coverage for Radiologist in minimum coverage amounts of $1,000,000 per
occurrence and $1,000,000 in the aggregate with coverage binders to include (a)
patient injury liability coverage and (b) hired/non-owned vehicle coverage.

                              PERMANENT DISABILITY
                              --------------------

         Notwithstanding anything to the contrary contained in this Agreement,
if, during the Term hereof, Radiologist suffers a Permanent Disability
(hereinafter defined), the Company shall continue to pay Radiologist the Annual
Fee during the period of such disability, provided, however, that in the event
Radiologist is so disabled for a period of sixty (60) consecutive days or ninety
(90) days in any year during the Term hereof (the "Disability Period") -1- , the
Company may terminate this Agreement at any time after any such Disability
Period. The term "Permanent Disability" shall mean the inability of Radiologist
to perform a material portion of his Services under this Agreement as determined
by an independent physician selected by the Company.

                                   ARTICLE 10
                   CONFIDENTIALITY AND NON-DISCLOSURE COVENANT
                   -------------------------------------------

         During the Term of this Agreement, Radiologist hereby acknowledges that
he will obtain and be entrusted with unpublished and material confidential and
proprietary information relating to the Company's (for purposes of this Section
10, this shall include Premier, any affiliated entity, and any entity which
owns, operates or manages a Covered PET Center), prospective locations or sites
for Additional PET Centers, present and proposed business and operations of the
Company and the PET Centers and Additional PET Centers, including, without
limitation, financial information relating to the present and proposed business
and operations with respect to the Company, Premier and such imaging centers,
the cost and pricing of the Company's and Premier's services, proposed
acquisitions of the Company, the terms of all material agreements to which the

                                      -10-
<PAGE>

Company or Premier are parties and/or otherwise relating to all of such imaging
centers, and the sources and terms of the Company's and Premier's existing or
proposed debt, equity or equipment financing. All of such information that may
be obtained by Radiologist shall, for purposes hereof, be referred to herein as
"Confidential Information". Radiologist hereby agrees that, unless the
Confidential Information becomes publicly known through legitimate origin not
involving any improper act or omission of Radiologist, neither he, nor any
entity or person owned or controlled directly or indirectly by him, shall,
during the Term of this Agreement or thereafter, use for his own benefit or for
the benefit of others for any purpose and in any manner whatsoever, divulge to
any person, firm, corporation or other entity or otherwise publish or disclose
any Confidential Information (except as necessary in connection with the
performance of Radiologist's services under this Agreement). This Section 10
shall survive the expiration or termination of this Agreement. Notwithstanding
the foregoing, Radiologist shall not be in breach of this covenant with respect
to any use or disclosure of any Confidential Information by him which is or
becomes available in the public domain or is required as a result of any legal
process served upon him in any judicial or administrative proceeding (provided
that Radiologist provides prompt notice of any such process served upon him in
order to enable the Company to timely contest the same, at its expense), or was
obtained by Radiologist from a third party without such third party's breach of
agreement or obligation of trust.

                                   ARTICLE 11
                        NON-COMPETITION; NON-SOLICITATION
                        ---------------------------------

         11.1.    Radiologist acknowledges and recognizes the highly competitive
nature of the business and proposed business of the Company and hereby agrees
that, during the Term hereof and for a period of one year after the expiration
or any earlier termination of the Term of this Agreement (other than any such
earlier termination by Radiologist pursuant to the provisions of Section 4.3(g)
hereof) (such period to be referred to hereinafter as the "Applicable Period"),
he will not, directly or indirectly, on his own behalf or in the service of or
on behalf of others, whether as an officer, director, stockholder, partner,
trustee, principal, employee, consultant, agent, or owner of any capital stock,
partnership interest or other interest in any corporation, partnership or other
entity, or in any other capacity, own an interest in, perform any services or
conduct any activity for or on behalf of any entity (including any institution)
which is engaged in reading and interpreting diagnostic imaging scans for any
entity which owns, operates, or manages a diagnostic imaging center or other
facility providing PET and/or magnetic resonance imaging services ("MRI") and
which is located or provides services to patients within an area consisting of a
twenty-five (25) mile radius of any facility which is owned and/or operated
and/or managed, in whole or in part, by the Company (for these purposes to
include Premier, and any subsidiary or affiliate of the Company or Premier) (a
"Facility"), (such prohibited activities being referred to herein as a
"Precluded Business Activity"). Radiologist acknowledges that, due to the nature
of the Company's business, it is essential to provide for as broad a
geographical limitation as possible with respect to the aforementioned covenant
inasmuch as the Company will make substantial capital investments in and
commitments for each of its aforementioned Facilities. Without limiting the
generality of the foregoing, it is expressly understood and agreed that although

                                      -11-
<PAGE>

Radiologist and the Company consider the restrictions contained in this Section
11.1 to be reasonable, the Radiologist agrees that in the event it is finally
judicially determined by a court of competent jurisdiction that the specified
time period or geographical area or scope of the foregoing restriction is
unreasonable, arbitrary, or against public policy, contrary to law, invalid and
unenforceable, the remaining provisions of this Agreement (including the
remaining provisions of this Section) shall not be rendered void, shall not be
affected thereby and shall remain in full force and effect and the provisions
hereof which are the subject of any such judicial determination shall be deemed
amended to apply to any such lesser time period, geographical area, or scope
which is judicially determined or indicated to be reasonable, non-arbitrary and
not violative of public policy, not contrary to law, invalid and/or
unenforceable and such provisions, as modified, may be enforced by the Company
against the Radiologist in accordance with the terms hereof. Notwithstanding the
foregoing, nothing contained in this Section is intended to nor shall preclude
the ownership by Radiologist of not more than five (5%) percent of the
outstanding securities of any publicly owned corporation or other entity engaged
in a Precluded Business Activity, provided that such ownership is solely for
investment purposes and is not coupled with any working relationship between
Radiologist and such corporation or entity.

         11.2.    Radiologist will not, at any time during or after the Term
hereof, directly or indirectly, (i) solicit the business of any referring
physician, client or customer or partner (i.e., any equity owner of any imaging
facility owned, operated or managed by the Company, Premier, or any subsidiary
or affiliate of the Company) of the Company for purposes of performing PET or
MRI procedures, or (ii) solicit, interfere with, or endeavor either to cause any
employee, agent, consultant, customer or supplier of the Company or any such
entity to leave his or her employment with the Company, or terminate its
relationship with the Company or any such entity, or (iii) induce or attempt to
induce any such employee, agent, consultant, customer or supplier to breach any
employment agreement or other agreement or arrangement that such employee,
agent, consultant, customer, or supplier may have with the Company or any such
entity.

         11.3.    Radiologist hereby acknowledges that the provisions of Section
10 and of this Section 11 are necessary for the protection of the Company's
business and goodwill and are considered by Radiologist to be fair and
reasonable. Radiologist further acknowledges that he has fully and carefully
reviewed, considered and understands all of the restrictions imposed upon him
under Section 10 and this Section 11. Accordingly, Radiologist hereby
acknowledges and agrees that in the event of any actual or threatened breach by
him of the provisions of Section 10 and/or this Section 11, there will be no
adequate remedy at law for any such breach or threatened breach and that any
such breach or threatened breach may cause irreparable harm to the Company and,
therefore, Radiologist hereby consents in any such instance to the granting of
injunctive or other equitable relief to the Company, as a non-exclusive remedy,
in any court of competent jurisdiction, without the necessity of showing any
actual damage or that monetary damages would not provide an adequate remedy at a
law or posting a bond therefor.

         11.4.    Radiologist hereby represents and warrants to the Company that
the only restrictive covenants that Radiologist is bound by as of the date
hereof are set forth on Exhibit A hereto.

                                   ARTICLE 12
                                     RECORDS
                                     -------

         The ownership and right of control of all books, records, reports and
supporting documents prepared in connection with the interpretation of all
Imaging Scans and all documents in support of or relating thereto shall be and
remain the sole property of the Company. Radiologist hereby agrees that, upon
the termination or expiration of this Agreement, it will promptly return to the
Company all such books, records, reports and supporting documents which are then
in Radiologist's possession or under its control. During and after the Term of
this Agreement, the Company shall, consistent with applicable laws, rules and
regulations, cooperate with Radiologist's requests for access to such records
and shall provide copies of such records at no charge to the Radiologist as the
Radiologist may reasonably require from time to time in order to evaluate a case
at the request of a patient, answer a subpoena, or defend a lawsuit (except as
otherwise prohibited by applicable law).

                                   ARTICLE 13
                                 INDEMNIFICATION
                                 ---------------

         13.1.    The Company shall indemnify and fully defend, save and hold
harmless Radiologist, if Radiologist shall at any time or from time to time
during the Term hereof suffer any damage, liability, loss, cost or expense
(including all reasonable attorneys' fees and expenses of counsel reasonably
satisfactory to the Company) (collectively, the "Losses") arising out of or
resulting from:

                  (a)      any untruth or inaccuracy in any representation or
warranty of the Company, or the breach of any representation or warranty of the
Company, contained in this Agreement; or

                  (b)      any failure of the Company to perform or observe any
term, provision, covenant or agreement contained in this Agreement.

         13.2.    Radiologist shall indemnify and fully defend, save and hold
harmless the Company and Premier, if the Company or Premier shall at any time or
from time to time suffer any Losses arising out of or resulting from:

                  (a)      any untruth or inaccuracy in any representation or
warranty of Radiologist, or the breach of any representation or warranty of
Radiologist, contained in this Agreement; or

                                      -13-
<PAGE>

                  (b)      any failure of Radiologist to properly perform his
Services under this Agreement, or any failure to perform or observe any term,
provision, covenant or agreement contained in this Agreement.

         13.3.    If, with respect to a third party, an event occurs or is
alleged to have occurred and either party hereto asserts that the other has
become obligated to provide indemnification under this Article 13 (an "Indemnity
Claim"), the party seeking indemnification (the "Indemnitee") shall give written
notice promptly to the indemnifying party (the "Indemnitor"). The failure to so
notify Indemnitor shall not, however, release Indemnitor from any obligation or
liability it may have to such Indemnitee under this Section unless such failure
materially prejudices Indemnitor. Indemnitor agrees to defend, contest or
otherwise protect the Indemnitee against any Indemnity Claim at Indemnitor's
sole cost and expense. The Indemnitee shall have the right, but not the
obligation, to participate at its own expense in the defense thereof by counsel
of the Indemnitee's choice and shall in any event cooperate with and assist
Indemnitor to the extent reasonably possible. If Indemnitor fails to timely
defend, contest or otherwise protect against such Indemnity Claim, the
Indemnitee shall have the right to do so, including, without limitation, the
right to make any compromise or settlement thereof, and the Indemnitee shall be
entitled to recover the entire cost thereof from Indemnitor, including, without
limitation, reasonable attorneys' fees, disbursements and amounts paid as the
result of such Indemnity Claim , and Indemnitor shall be bound by any
determination made in such Indemnity Claim or any compromise or settlement
effected by the Indemnitee. If Indemnitor assumes the defense of any Indemnity
Claim , (a) it will be conclusively established for purposes of this Agreement
that the claims made in that Indemnity Claim are within the scope of and subject
to indemnification hereunder, (b) no compromise or settlement of such claims may
be effected by Indemnitor without the Indemnitee's written consent unless (i)
there is no finding or admission of any violation of federal, state, local,
municipal, foreign, international, multinational or other administrative order,
law, ordinance, principal of common law, regulation, statute or treaty or any
violation of the rights of any person and no effect on any other claims that may
be made against the Indemnitee and (ii) the sole relief provided is monetary
damages that are paid in full by Indemnitor; and (c) the Indemnitee will have no
liability with respect to any compromise or settlement of such claims effected
without its written consent. Notwithstanding anything to the contrary contained
in Sections 13.1, 13.2 or in this Section 13.3, if any Indemnitee settles or
compromises any Indemnity Claim without Indemnitor's prior written consent,
Indemnitor shall have no obligation for indemnification under Sections 13.1,
13.2 or this Section 13.3.

                                   ARTICLE 14
                                  MISCELLANEOUS
                                  -------------

         14.1.    This Agreement constitutes the sole and entire agreement
between the parties hereto with respect to the subject matter hereof and
supersedes all prior agreements, representations, warranties, statements,
promises, information, arrangements and understandings, whether oral or written,
express or implied, between the parties hereto with respect to the subject
matter hereof (including that certain Letter of Intent dated as of October 11,
2005 between Radiologist and the Company). This Agreement may not be changed or
modified except by an instrument in writing signed by the party to be bound
thereby.

         14.3.    Neither party hereto may assign this Agreement or their

writing and signed by the party to be bound thereby. The waiver by either party
hereto of a breach of any provision of this Agreement, or of any representation,

                                    ---------

                     RADIOLOGIST'S NON-COMPETE RESTRICTIONS
                     --------------------------------------

         (a)      Pursuant to that certain Professional Services Agreement dated
effective as of May 1, 2005 by and between RCOA Florida I, LLC ("RCOA Florida")
and ADIP, Radiologist is bound by a covenant not to solicit that will be valid
and in full force and effect from two (2) years following the date on which such
agreement is terminated, and that prohibits ADIP and its employed or retained
radiologists including Radiologist from (i) soliciting or inducing employees or
agents of RCOA Florida to terminate their relationship with RCOA Florida or to
engage in any activity that would violate any of the following, (ii) soliciting
or inducing hospitals, diagnostic imaging centers, physicians, patients,
providers or other current customers of RCOA Florida ("Clients") to terminate
their relationship with RCOA Florida, or to do business with any other entity
engaged in any aspect of the providing of mobile or fixed-site PET/CT imaging
services, (iii) interfering with or disrupting or attempting to disrupt, or the
taking of any action that could reasonably be expected to disrupt any past or
present or prospective relationship, contractual or otherwise, between RCOA
Florida and a Client or any other entity with which RCOA Florida or any of its
subsidiaries do business or (iv) assisting others to engage in any of the
foregoing activities. These provisions have no effect on the activities of
Radiologist outside a fifteen (15) mile radius of the center (the "Territory")
located at 16110 Jog Road, Suite 200, Delray Beach, Florida (the "Center")
provided the solicitations of Clients inside the Territory are confined to
