                           ACCOUNTANTS' REVIEW REPORT


TO THE BOARD OF DIRECTORS
Mobile P.E.T. Systems, Inc.

We have reviewed the accompanying consolidated balance sheets of Mobile P.E.T.
Systems, Inc. and subsidiaries as of September 30, 2000 and 1999, and the
related consolidated statements of operations and cash flows for the three
months then ended, in accordance with Statements on Standards for Accounting and
Review Services issued by the American Institute of Certified Public
Accountants. All information included in these consolidated financial statements
is the representation of the management of Mobile P.E.T. Systems, Inc. and
subsidiaries.

A review consists principally of inquiries of Company personnel and analytical
procedures applied to financial data. It is substantially less in scope than an
audit in accordance with generally accepted auditing standards, the objective of
which is the expression of an opinion regarding the consolidated financial
statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying consolidated financial statements in order for them
to be in conformity with generally accepted accounting principles.

                  MOBILE P.E.T. SYSTEMS, INC. AND SUBSIDIARIES
                    For the quarter ended September 30, 2000

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - THE COMPANY

     Mobile P.E.T. Systems, Inc. (the "Company") and subsidiaries were organized
     to provide Positron Emission Tomography (PET) systems and services to
     hospitals and other health care providers on a mobile, shared user basis.
     The Company's PET services include the provision of high technology imaging
     systems, technologists to operate the imaging systems, the management of
     day-to-day operations and educational and marketing support. The Company
     has operations in the United States and the United Kingdom.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Presentation

     The consolidated financial statements include the accounts of the Company
     and its wholly owned subsidiaries. All significant intercompany
     transactions have been eliminated in consolidation.

     Cash and Cash Equivalents

     The Company considers all highly liquid debt instruments purchased with a
     maturity of three months or less to be cash and cash equivalents.

     Property, Equipment and Leasehold Improvements

     Property and equipment are recorded at cost less depreciation and
     amortization. Depreciation and amortization are accounted for on the
     straight-line method based on estimated useful lives. The amortization of
     leasehold improvements is based on the shorter of the lease term or the
     life of the improvement. Betterments and large renewals, which extend the
     life of an asset, are capitalized; whereas, maintenance and repairs and
     small renewals are expensed as incurred.

     Foreign Currency Translation

     The financial statements of all foreign subsidiaries were prepared in their
     respective local currencies and translated into U.S. dollars based on the
     current exchange rate at the end of the period for the balance sheet and a
     weighted-average rate for the period on the statement of operations.
     Translation adjustments are reflected as foreign currency translation
     adjustments in shareholders' equity and accordingly have no effect on net
     loss. Transaction adjustments for all foreign subsidiaries are included in
     the statements of operation.

     Estimates

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities, and
     disclosure of contingent assets and liabilities at the date of the
     financial statements, and the reported amounts of revenue and expenses
     during the reporting period. Actual results could differ from those
     estimates.

     Income Taxes

     The Company accounts for income taxes under Statement of Financial
     Accounting Standards No. 109, "Accounting for Income Taxes." This statement
     requires an asset and liability approach to account for


                                       7
<PAGE>   10

     income taxes. The Company provides deferred income taxes for temporary
     differences that will result in taxable or deductible amounts in future
     years based on the reporting of certain costs in different periods for
     financial and income tax purposes.

     Stock Option Plans

     The Company has adopted SFAS No. 123 "Accounting for Stock-Based
     Compensation," which permits entities to recognize as expense over the
     vesting period the fair value of all stock-based awards on the date of
     grant. Alternatively, SFAS No. 123 also allows entities to continue to
     apply the provisions of APB Opinion No. 25 "Accounting for Stock Issued to
     Employees," and provide pro forma net income and pro forma earnings per
     share disclosures for employee stock option grants as if the
     fair-value-based method defined in SFAS No. 123 has been applied. The
     Company has elected to apply the provisions of APB Opinion No. 25 and
     provide the pro forma disclosure provisions of SFAS No. 123.

NOTE 3 - ACQUISITIONS

     Mobile P.E.T. Systems, Inc. was incorporated in the State of Nevada on
     December 1, 1998. On December 22, 1998, Mobile P.E.T Systems, Inc.'s
     shareholders exchanged all of the 7,000,000 shares of outstanding common
     stock for 7,000,000 shares of common stock in Colony International
     Incorporated, prior to that named American Coin and Stamp, Inc.,
     incorporated in the State of Delaware on August 21, 1995 and its wholly
     owned subsidiary Colony International Incorporated, incorporated in the
     State of Nevada on April 25, 1995. This exchange of shares has been
     accounted for as a reverse merger, under the purchase method of accounting.
     Accordingly, the combination of the Mobile P.E.T. Systems, Inc. and Colony
     International Incorporated and subsidiary is recorded as a recapitalization
     of the shareholders' equity of Mobile P.E.T. Systems, Inc., the surviving
     corporation and for accounting purposes the financial statements presented
     are those of Mobile P.E.T. Systems, Inc. Accordingly, pro-forma information
     has not been presented. Mobile P.E.T Systems, Inc. reported no sales and a
     net loss of $15,200 prior to the acquisition. The other individual
     companies reported no net sales and no net income or loss prior to the
     acquisition.

     On December 10, 1999, the Company incorporated a wholly owned subsidiary,
     The London P.E.T. Centre Limited, a United Kingdom private limited company.
     On December 17, 1999 the Company incorporated two wholly owned
     subsidiaries, Mobile P.E.T. Leasing Limited, a United Kingdom private
     limited company and Mobile P.E.T. Systems (UK) Limited, a United Kingdom
     private limited company.

     (10,000,000) shares of preferred stock having one hundredth of a cent
     ($0.0001) par value per share. On March 1, 2000 the Company designated and
     issued sixty (60) shares 8% Cumulative Convertible Redeemable Preferred,
     Series A Stock for cash in the amount of $2,700,000, net of acquisition
     fees. These shares of 8% Cumulative Convertible Redeemable Preferred,
     Series A Stock have no voting rights, have a liquidation value of $50,000
     per share, and accrue dividends at a rate of eight percent (8%) per annum
     per share on the liquidation value payable upon conversion. The total
     liquidation value of the shares outstanding at September 30, 2000 in the
     amount of $3,000,000 is classified on the Company's balance sheet as
     preferred stock. Cumulative preferred dividends are payable upon conversion

     Stock shall be paid the liquidation value plus all accrued dividends at the
     date of liquidation, dissolution or winding up of the affairs before any
     payment to other shareholders. At the option of the holders, the 8%
     Cumulative Convertible Redeemable Preferred, Series A Stock and the
     cumulative preferred dividends in arrears are convertible into shares of
     common stock determined by dividing $50,000 by the conversion price of the
     lesser of $5 or 75% of the average of the closing bid price of common stock

     The Company accounts for stock-based compensation using the intrinsic value
     method prescribed by Accounting Principles Board Opinion No. 25,
     "Accounting for Stock Issued to Employees," under which no compensation
     cost for stock options is recognized for the stock option awards granted at
     or above fair market value. During the three month period ended September
     30, 2000, the Company recognized compensation expense of $92,331. During
     the three month period ended September 30, 1999, the Company did not
     recognize any compensation expense.

     Had compensation expense for the Company's 1999 Stock Option Plan been
     determined based upon fair values at the grant dates for awards under the
     plan in accordance with SFAS No. 123, "Accounting for Stock-Based
     Compensation," the Company's net loss and loss per share would have been
     increased to the pro forma amounts indicated below. Additional stock option
     awards are anticipated in future years.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

The following discussion and analysis of our financial condition and results of
operations should be read in conjunction with the financial statements and the
related notes. This quarterly report of Form 10-QSB contains forward-looking
statements based upon current expectations that involve risks and uncertainties,
such as our plans, objectives, expectations and intentions. For this purpose,
any statements contained in it that are not statements of historical fact should
be regarded as forward-looking statements within the meaning of Section 27A of
the Securities Act of 1933 and Section 21E of the Securities Exchange Act of
1934. For example, the words "believes," "anticipates," "plans," "intends,"
"will," "may" and "expects," or any variation of these words including the
negative of these words, are intended to identify forward-looking statements.
For a more detailed description of these risk factors, please see Item 1
"Business - Risk Factors" of our annual report on Form 10-KSB filed with the
Securities and Exchange Commission on October 11, 2000.

OVERVIEW

Our company and our subsidiaries are a medical service provider operating mobile
Positron Emission Tomography, or PET, molecular imaging systems for hospitals
and other health care providers on a mobile, shared user basis in selected
marketplaces in the United States. We provide the PET imaging system housed in a
mobile coach or in a dedicated facility. We also provide the technical personnel
who operate the equipment and implement the PET procedure under the direction of
hospital physicians. Our PET services include the management of day-to-day
operations and educational and marketing support. Our services enable leading as
well as small to mid-size hospitals to gain access to advanced diagnostic
imaging technology and related value-added services without making a substantial
investment in equipment and personal.

We have operations in the United States and a dedicated PET facility in the
United Kingdom. We believe there may be opportunities for shared mobile PET
services in the United Kingdom and certain European markets. On December 10,
1999, we incorporated a wholly owned subsidiary, The London P.E.T. Centre
Limited, a United Kingdom private limited company. On December 17, 1999, we
incorporated two wholly owned subsidiaries, Mobile P.E.T. Leasing Limited, a
United Kingdom private limited company and Mobile P.E.T. Systems (UK) Limited, a
United Kingdom private limited company.

We have measured the financial position and results of operations of our United
Kingdom subsidiaries using local currency as the functional currency. We have
translated our assets and liabilities into U.S. dollars at the rates of exchange
at the balance sheet date. We have translated our statements of operations items
using the average exchange rates prevailing throughout the reporting period. We
have accumulated the translation gains or losses resulting from the changes in
the exchange rates from quarter-to-quarter in a separate component of
shareholders' equity. We have reflected the transaction gains and losses in the
cash flow as the effect of exchange rate changes on cash.

Our consolidated revenues for our first quarter ending September 30, 2000
approximated $841,000 compared to our first quarter of operations ended
September 30, 1999, in which we had revenues of $80,000 as we emerged from our
development stage period in the United States establishing the management and
operating infrastructure to provide PET systems and services to hospitals and
other health care providers on a mobile, shared user basis. The London P.E.T.
Centre Limited, our wholly owned United Kingdom subsidiary, emerged from the
development stage late in the fourth quarter ended June 30, 2000 and prior to
that our efforts were principally devoted to organizational activities,
marketing efforts and placing the first fixed site PET system into service in
London.

                                       19
<PAGE>   22

We continue our development and expansion efforts of organizational activities,
infrastructure, capital, marketing, and the placement of additional mobile and
fixed site PET systems. We anticipate we will incur additional losses as we
pursue our development efforts into the first half of this fiscal year at which
time we expect that cash flow from revenues will become sufficient to cover our
cost of services on a monthly basis going forward.

Our future revenues will principally be a function of the number of mobile units
in service, scan volumes and fees per scan. We generate substantially all of our
revenues from exclusive five-year contracts with hospitals and health care
providers. While we have not written off an account to date there can be no
assurance that this trend will continue and accordingly, we have established a
conservative allowance for uncollectable accounts receivable.

The principal component of our operating costs includes salaries and benefits
paid to technologists and drivers, marketing, equipment leasing, system
maintenance, insurance and transportation costs. Because a majority of these are
fixed, increased revenues as a result of higher scan volumes may significantly
improve our future profitability potential, while lower scan volumes may result
in lower profitability.

Since our inception, we have incurred significant losses and through September
30, 2000, we have incurred a consolidated net loss approximating $10,678,800.
For the quarter ended September 30, 2000, we experienced a consolidated net loss
from operations of $2,263,000. We expect to experience operating losses and
negative cash flow from operations until later this fiscal year 2001, when we
anticipate reaching and exceeding break even on a monthly basis. We anticipate
our losses during this next quarter may increase from current levels as we incur
costs and expenses related to infrastructure development and staffing, marketing
and sales activities and other capital expenditures. As a result, in order to
achieve and maintain profitability, we will need to continue to generate
significant revenues.

We raised approximately $1.5 million dollars of new equity capital through the
issuance of preferred stock in a domestic and international private placement in
two tranches. During the first quarter ended September 30, 2000, we designated
thirty shares and issued twenty shares of cumulative convertible redeemable
Series B preferred stock, along with 50,000 warrants to purchase shares of
common stock at an exercise price of $3 per share, for $885,000, net of issuing
costs, as the first tranche of the financing. During November 2000, we issued an
additional ten shares of cumulative convertible redeemable Series B preferred
stock, along with 29,851 warrants to purchase shares of common stock at an
exercise price of $2.5125 per share for $500,000, as the second tranche of the
financing. During the prior year ended June 30, 2000, we designated and issued
sixty shares of cumulative convertible redeemable Series A preferred stock for
$2,700,000 net of issuance costs and 120,000 warrants to purchase shares of
common stock at an exercise price of $5 per share. Both Series A and Series B
preferred shares have no voting rights, have a liquidation value of $50,000 per
share, and accrue dividends at a rate of 8% on the liquidation value payable
upon conversion. The investor of the Series A preferred stock also agreed to
purchase shares of common stock of the Company with a value of up to $10,000,000
in tranches for a purchase price of approximately eighty five percent of the
average closing bid price of the five prior days per share. In October 2000, we
issued 25,000 shares of common stock for $1.90 per share, pursuant to the
exercise of an outstanding option.

We have a limited operating history on which to base an evaluation of our
business and prospects. You must consider our prospects in light of the risks,
expenses and difficulties frequently encountered by companies in their early
stage of development. To address these risks, we must establish, maintain and
expand our customer base, implement and successfully execute our business and
marketing strategy, provide superior customer service, anticipate and respond to
competitive developments and attract, retain and motivate qualified personnel.
We cannot assure you that we will be successful in addressing these risks, and
our failure to do so could have a negative impact on our business, operating
results and financial condition.

RESULTS OF OPERATIONS

The prior quarter ended September 30, 1999 was our first quarter of operations.
During the quarter ended September 30, 1999, we placed our first mobile unit
into operation, which generated revenues and incurred operating costs in
addition to those related to establishing the management and operating
infrastructure to provide PET systems and services to health care providers on a
mobile, shared user basis. These factors make it difficult to draw informative
conclusions by comparing the quarter ended September 30, 1999 and the quarter
ended September 30, 2000.

For the quarter ended September 30, 2000

Our net loss from operations was $2,263,000 and our net loss available to common
shareholders, after preferred stock dividend, was $2,539,400 or $0.18 per share
for the quarter ended September 30, 2000, compared to the net loss approximating
$704,800 or $0.05 per share for the quarter ended September 30, 1999.

We took delivery on our first PET unit in July 1999 and began accruing revenues
in August 1999. For the quarter ended September 30, 2000, we had five units
accepted and placed into service, generating revenues of $841,000 and incurring
cost of services of $612,800, or 73%, compared to $80,000 in revenues and
$43,500, or 54%, in cost of services for the quarter ended September 30, 1999.
As a result of these activities, accounts receivables increased to $567,500, net
of allowances for doubtful accounts, as of September 30, 2000, as compared to
accounts receivables of $135,600 for the prior quarter ended September 30, 1999.
The costs of service revenues represent salaries paid to technologists and
drivers, depreciation on capital leases, system maintenance, transportation and
insurance on our mobile PET systems.

General and administrative expenses for the quarter ended September 30, 2000
were $2,252,700, as compared to $700,000 for the quarter ended September 30,
1999. We incurred increased general and administrative expenses due primarily to
the growth in staff and related expenses incurred in operating our five Mobile
PET units compared to our one unit in the quarter ended September 30, 1999. In
addition, we continue to incur costs in building our infrastructure and incur
costs incurred in advertising and marketing our mobile PET services.

Our interest income was $13,300 for the quarter ended September 30, 2000, as
compared to $6,700 for the quarter ended September 30, 1999. Our $6,600 increase
in interest income for the quarter ended September 30, 2000 was the result of
quarterly accrued interest on the $200,000, 15% Subordinated Equity
Participation Agreement and money market funds. Our $6,700 interest income for
the quarter ended September 30, 1999 was the result of invested funds. Our
increased interest expense of $244,600 for the quarter ended September 30, 2000,
as compared to the interest expense of $47,000 for the quarter ended September
30, 1999, was principally due to the capitalization of our equipment leases of
image scanners, coaches and computer equipment.

LIQUIDITY AND CAPITAL RESOURCES

At September 30, 2000, our total assets were $12,710,800, compared to $3,815,600
at September 30, 1999. Our current assets at September 30, 2000 totaled
$2,809,000 and our current liabilities were $3,199,400, as compared to September
30, 1999 that reflected current assets of $1,551,000 and current liabilities of
$77,300. Shareholders' equity at September 30, 2000 increased to $2,458,600 from
$2,303,700, due primarily to the issuance of 20 shares of Series B Convertible
Preferred Stock in the amount of $885,000, net of issuance costs, stock
subscriptions of $547,500 and a net loss of $2,263,000 incurred in the quarter
ended September 30, 2000. In the comparable quarter ended September 30, 1999,
shareholders' equity was primarily the result of 51 shares of common stock
issued from subscriptions paid in the amount of $285,000, net of offering costs
and a quarterly net loss of $704,800.

                                       21

<PAGE>   24

Our foreign currency translation adjustment in shareholders' equity amounted to
$30,200 at September 30, 2000 and there was no comparable adjustment at
September 30, 1999. We have reflected the transaction gains and losses in the
cash flow as the effect of exchange rate changes on cash of $73,100 for the
quarter ended September 30, 2000, with no comparable cash flow effect at
September 30, 1999.

Our net cash used in investing activities for the quarter ended September 30,
2000 was $100,600, as compared to $300,400 in the prior quarter ended September
30, 1999. This difference is primarily a result of the $111,400 we invested in
computers and related equipment for our business and personnel growth. In July
1999, we purchased a coach for $273,400 and made a deposit of $637,500 for our
second mobile PET system. We sold them to a leasing company in late December
1999, as part of a five year lease agreement, resulting in a financing lease for
the coach and the imaging system, consistent with the capitalization of our
mobile system equipment leases. In August 2000, we accepted and entered into two
financing leases, approximating $3 million for the coach and the imaging system,
as part of a five-year lease agreement with a leasing company for our fourth and
fifth mobile PET systems.

The net cash provided by our financing activities for the quarter ended
September 30, 2000 was $868,800, a result of the private placement and issuance
of 20 shares of Series B Convertible Preferred Stock in the amount of $885,000;
the proceeds from a $200,000 bridge financing and payments of $216,200 on
obligations under capital leases, as compared to $285,000 for the quarter ended
September 30, 1999, a result of the issuance of 515,000 shares of common stock,
net of issuing costs.

We have experienced a substantial increase in our capital expenditures since our
inception, consistent with our growth in operations and staffing, and we
anticipate that this will continue for the foreseeable future. Additionally, we
continue to evaluate business investments, geographic service expansion and
service offerings. We cannot be certain that the underlying assumed levels of
revenues and expenses will prove to be accurate. While we do not have any
binding commitments for any additional funding, we may seek to obtain additional
funding through public or private financings or other arrangements. If we are
unable to obtain such funding or if such funding is insufficient, we may be
unable to develop or enhance our services, take advantage of business
opportunities or respond to competitive pressures, any of which could have a
materially adverse impact on our business, operating results and financial
condition.

ITEM 2. CHANGES IN SECURITIES

On September 21, 2000, we entered into a Securities Purchase Agreement. As part
