                        RADIOLOGIX, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1. GENERAL:

     Radiologix, Inc. (together with its subsidiaries, "Radiologix" or the
"Company"), a Delaware corporation, is a leading provider of radiology services
in the United States through its ownership and operation of technologically
advanced, multi-modality outpatient diagnostic imaging centers. The Company's
full-service imaging centers typically offer a broad array of diagnostic imaging
procedures such as x-ray, magnetic resonance imaging ("MRI"), computed
tomography ("CT"), mammography, dual energy x-ray absorptiometry ("DEXA"),
ultrasound, nuclear medicine and positron emission tomography ("PET"), as well
as general radiography and fluoroscopy. Physicians use the diagnostic images,
which result from these procedures, and the radiology reports based on the
images, to diagnose and manage diseases and injuries of their patients. Ordering
physicians rely extensively on this type of diagnostic information in making
health care treatment decisions.

     As of September 30, 2001, the Company owns, operates or shares ownership in
imaging equipment at 120 locations and provides management services to ten
contracted radiology practices. The Company's imaging centers are located in 18
states and the District of Columbia, with concentrated geographic coverage in
markets located in California, Florida, Kansas, Maryland, New York, Texas,
Virginia and Washington, D.C.

     Physician services are provided at all of the Company's imaging centers
associated with its ten contracted radiology practices under the terms of
service agreements, seven of which expire in November 2037, with the other three
expiring in 2038. Under the terms of the service agreements, the Company
provides administrative, management, technical and non-medical services to
contracted radiology practices that provide professional services in connection
with our diagnostic imaging centers, and to hospitals and radiology practices
with which we operate joint ventures. The administrative services are intended
to improve radiology practice or joint venture profitability, efficiency and
effectiveness, and leverage our existing infrastructure. The service agreements
cannot be terminated by either party without cause, consisting primarily of
bankruptcy or material default. However, under certain conditions, the Company
can terminate the service agreement if the number of physicians in a practice
falls below a certain percentage.


2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Basis of Presentation

     The consolidated financial statements have been prepared in accordance with
accounting principles generally accepted in the United States and include the
accounts of the Company and its wholly owned and majority owned subsidiaries.
All significant intercompany accounts and transactions have been eliminated in
consolidation.

Recent Accounting Pronouncement

     Statement of Financial Accounting Standards No. 142, "Goodwill and Other
Intangible Assets" ("SFAS No. 142"), becomes effective for the Company on
January 1, 2002. SFAS No. 142 requires that goodwill and other intangible assets
with an indefinite useful life no longer be amortized as expenses of operations,
but rather carried on the balance sheet as permanent assets. These intangible
assets are to be subject to at least annual assessments for impairment by
applying a fair-value-based test. Amortization of goodwill and other
indefinite-lived intangible assets amounted to $937,400 ($562,400 on an
after-tax basis) for the first nine months of 2001 and is projected to amount to
$1,249,800 ($749,900 on an after-tax basis) for the full year of 2001. These
expense amounts, under SFAS 142, will not be recorded in years after 2001. The
Company is developing plans to determine fair values of its operations in which
goodwill and other indefinite-lived intangibles have been recorded and will
assess whether an impairment charge is warranted as of January 1, 2002, or at
any other assessment dates. The Company's service agreements, included in the
consolidated balance sheets as intangible assets, net, are not considered to
have an indefinite useful life and will continue to be amortized over a useful
life of 25 years.

Service Fee Revenues

     Service fee revenues represent contracted radiology practices revenue less
amounts retained by contracted radiology practices. The amounts retained by
contracted radiology practices represent amounts paid to the contracted
radiology practices pursuant to the service agreements between the Company and
the contracted radiology practices. Under the service agreements, the Company
provides each physician group with the facilities and equipment used in its
medical practice, assumes responsibility for the management of the operations of
the practice, and employs substantially all of the non-physician personnel
utilized by the group. The Company assists in negotiating managed care contracts
for the contracted radiology practices.

     The following table sets forth the amounts of revenue for the contracted
radiology practices and diagnostic imaging centers that would have been
presented in the consolidated statements of income had Radiologix met the
provisions of the Financial Accounting Standards Board's Emerging Issues Task
Force's abstract, Issue 97-2, "Application of FASB Statement No.94 and
Accounting Principles Board ("APB") Opinion No. 16 to Physician Practice
Management Entities and Certain Other Entities with Contractual Arrangements"

     The Company's service fee revenue is dependent upon the operating results
of its diagnostic imaging centers and the contracted radiology practices. Where
state law allows, service fees due under the service agreements are derived from
two distinct revenue streams: (1) 100% of the adjusted technical revenues as
defined in the service agreements; and (2) a negotiated percentage (typically
20% to 30%) of the adjusted professional revenues as defined in the service
agreement. In states where the law requires a flat fee structure, the Company
has negotiated a base service fee, which is equal to the fair market value of
the services provided under the service agreement and which is renegotiated each
year to equal the fair market value of the services provided under the service
agreement. The fixed fee structure results in the Company receiving
substantially the same amount of service fee as it would have received under its
negotiated percentage fee structure. Adjusted professional revenues and adjusted
technical revenues are determined by deducting certain contractually agreed-upon
expenses (non-physician salaries and benefits, rent, depreciation, insurance,
interest and other physician costs) from the contracted radiology practices'
revenue. Service fee revenues of the Company's subsidiary, Questar Imaging, Inc.
("Questar") are primarily derived from technical revenues generated from those
imaging centers.

3. LONG TERM DEBT

     On March 30, 2001, the Company and the existing bank group amended the bank
credit facility. Under the terms of the amended credit facility, the
$160,000,000 of borrowings consist of a $100,000,000 Term Loan and a $60,000,000
revolving credit facility, including a $5,000,000 Swing Line Facility. Under the
new amendment, the Company made $4,000,000 scheduled principal installments on
June 29, 2001 and September 28, 2001. Scheduled principal installments for the
fiscal year ended 2001 have been reduced from $47,100,000 under the prior
amended agreement to $12,000,000 under the new amendment. Scheduled principal
installments through September 30, 2002 consist of four quarterly installments
as follows: 1) $4,000,000 on December 31, 2001, 2) $6,000,000 on March 31, 2002,
3) $9,000,000 on June 30, 2002 and 4) $9,000,000 on September 30, 2002. Each of
the facilities will terminate on November 26, 2003. The interest rate is (i) an
adjusted LIBOR rate, plus an applicable margin which can vary from 3.00% to
4.00% dependent on certain financial ratios or (ii) the prime rate, plus an
applicable margin which can vary from 2.00% to 3.00%. In each case, the
applicable margin varies based on financial ratios maintained by the Company.
The credit facility includes certain restrictive covenants including
prohibitions on the payment of dividends, limitations on capital expenditures
and the maintenance of certain financial ratios (including minimum fixed charge
coverage ratio and maximum leverage ratio, as defined). At September 30, 2001,
the Company was in compliance with the covenants under the credit facility's
restrictive covenants. Borrowings under the credit facility are secured by all
service agreements, which the Company is, or becomes a party to, a pledge of the
stock of the Company's subsidiaries, and all of the Company's and its
wholly-owned subsidiaries' assets.

     The Company has a $23,824,263 convertible junior subordinated note, which
matures July 31, 2009, and bears interest, payable quarterly in cash or payment
in kind securities, at an annual rate of 8.0%. At August 1, 2001, the
convertible junior subordinated note was convertible into Radiologix's common
stock at the price of $7.52 per share. If by August 1, 2002 or August 1, 2003
the closing price of Radiologix's common stock has not exceeded $7.52 for 45 of
the 60 days of the determination period, the interest rate will be increased to
8.25% and 8.5%, respectively.


4. EARNINGS PER SHARE:

     Basic EPS is calculated by dividing net income available to common
stockholders by the weighted average number of common shares outstanding during
the period (including shares to be issued). Options, warrants, and other
potentially dilutive securities are excluded from the calculation of basic EPS.
Diluted EPS includes the options, warrants, and other potentially dilutive
securities that are excluded from basic EPS using the treasury stock method to
the extent that these securities are not anti-dilutive. Diluted EPS also
includes the effect of the convertible notes using the "if converted" method to
the extent the securities are not anti-dilutive.

     For the three months ended September 30, 2001 and 2000, under the "if
converted" method, approximately $286,000 and $264,000, respectively, of tax
effected interest savings and 2,866,094 and 2,318,841 weighted average shares
were included in the calculation of diluted EPS as an addition to net income and
weighted average shares outstanding, respectively. For the three months ended
September 30, 2001 and 2000, 373,671 and 318,009 shares, respectively, related
to stock options were included in the calculation of diluted EPS.

     For the nine months ended September 30, 2001 and 2000, under the "if
converted" method, approximately $832,000 and $771,000, respectively, of tax
effected interest savings and 2,501,258 and 2,318,841 weighted average shares
were included in the calculation of diluted EPS as an addition to net income and
weighted average shares outstanding, respectively. For the nine months ended
September 2001 and 2000, 303,498 and 288,967 shares, respectively, related to
stock options were included in the calculation of diluted EPS.

5. SEGMENT REPORTING:

     The Company has five reportable segments: Mid-Atlantic Region, Northeastern
Region, Central Region, Western Region and Questar. The Company's reportable
segments are strategic business units defined by management's division of
responsibilities. Each segment owns and operates imaging centers and (except for
Questar) provides management services to the imaging centers within their
respective segments.

     The accounting policies of the segments are the same as those described in
the summary of significant accounting policies except that the Company does not
allocate taxes associated with income to any of the regions. They are managed
separately because each segment operates under different contractual
arrangements, providing service to a diverse mix of patients and payors.

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

     The following discussion of the results of operations and financial
condition of the Company should be read in conjunction with the Company's
consolidated financial statements and notes thereto included in the Annual
Report on Form 10-K (as amended pursuant to Form 10-KA) for the year ended
December 31, 2000, and with the consolidated financial statements included in
this Form 10-Q.

OVERVIEW

     We are a leading provider of radiology services in the United States
through our (i) ownership and operation of technologically advanced,
multi-modality diagnostic imaging centers and (ii) provision of administrative,
management and information services to certain radiology business partners. We
derive the majority of our service fee revenues from providing the technical
component of radiology services performed at our freestanding imaging facilities
and pursuant to our out-sourced hospital relationships. In addition, we also
derive service fee revenues from providing management services to contracted
radiology practices pursuant to long-term service agreements.

     As of September 30, 2001, we owned or operated 120 imaging centers which
are located in 18 states and the District of Columbia, with concentrated
geographic coverage in markets located in California, Florida, Kansas, Maryland,
New York, Texas, Virginia and Washington D.C.


RESULTS OF OPERATIONS

     We focus on the results of operations through the division of its
contracted radiology practices into four designated regions of the United
States: Mid-Atlantic, Northeastern, Central, and Western regions. In addition,
we focus on the operations of the imaging centers of its subsidiary, Questar
Imaging, Inc. ("Questar"). Our operations in the each of the four designated
regions provide administrative, management and information services to
contracted radiology practices that provide professional services in connection
with our diagnostic imaging centers, and to hospitals and radiology practices
with which we operate joint ventures. The administrative services are intended
to improve radiology practice or joint venture profitability, efficiency and
effectiveness, and leverage our existing infrastructure. We have divided the
operations into the four regions and Questar only for purposes of the division
of internal management responsibilities, but do not focus on each of these
regions as a separate product line or make financial decisions as if they were
separate product lines. The Questar operations are looked at as a separate group
only from the perspective that the imaging centers of Questar do not have the
same type of management service agreement with physicians as we have with each
of the contracted radiology practices. In addition, any imaging centers, of
Questar that are in the same market as the operations of the contracted
radiology practices are not included in the service agreements of the contracted
radiology practices.

     The operating margin for the Mid-Atlantic was 31% and 34% for the nine
months ended September 30, 2001 and 2000, respectively. This decrease in the
operating margin was primarily a result of us acquiring more of the new
radiology equipment through leases during the third and fourth quarters of 2000
as an alternative to purchasing such equipment. The operating margin of the
Northeastern region was 26% and 29% for the nine months ended September 30, 2001
and 2000, respectively, and declined between periods as a result of a decrease
in the fixed fee recognized at one of the New York contracted practices. The
operating margin of the Central region was 34% and 36% for the nine months ended
September 30, 2001 and 2000, respectively. This decrease in the operating margin
between periods was partially due to the higher cost of certain radiology
supplies related to specialty procedures, which increased in volume during 2001.
The operating margin for the Western region was 24% and 26% for the nine months
ended September 30, 2001 and 2000, respectively. This decrease in the operating
margin between periods was primarily a result of continued managed care
pressures and the impact of economic changes related to increased salary costs.
The operating margin for Questar was 17% and 24% for the nine months ended
September 30, 2001 and 2000, respectively. This decrease was a result of
additional costs, such as maintenance agreements put in place, associated with
operating the facilities.

THREE MONTHS ENDED SEPTEMBER 30, 2001 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 2000

Service Fee Revenues

     Service fee revenues increased $6,688,000 or 10.7% for the three months
ended September 30, 2001 to $69,175,000 from $62,487,000 for the three months
ended September 30, 2000. The increase is primarily attributable to an increase
in volume. In addition, the increase in service fee revenues is attributable to
the operations maturing at the Questar imaging centers.

Field Salaries and Benefits

     Salaries and benefits increased $2,036,000 or 12.2% for the three months
ended September 30, 2001 to $18,690,000 from $16,654,000 for the three months
ended September 30, 2000. As a percentage of service fee revenues, these costs
were 27.0% and 26.7% in 2001 and 2000, respectively. The increase is primarily
due to increased benefit costs, as well as increased wage costs, primarily
technologists, experienced in certain markets, contributed to the higher
salaries and benefits.

Field Supplies

     Supplies increased $1,055,000 or 33.8% for the three months ended September
30, 2001 to $4,175,000 from $3,120,000 for the three months ended September 30,
2000. As a percentage of service fee revenues, these costs were 6.0% and 5.0% in
2001 and 2000, respectively. The increase in supplies as a percentage of service
fee revenues is primarily attributable to an increase in volume of specialty
procedures. These procedures require supplies with higher unit costs than
typically required for other types of imaging procedures.

Field Rent and Lease Expense

     Rent and lease expense increased $1,056,000 or 13.9% for the three months
ended September 30, 2001 to $8,639,000 from $7,583,000 for the three months
ended September 30, 2000. As a percentage of service fee revenues, these costs
were 12.5% and 12.1% in 2001 and 2000, respectively. The increase is primarily
the result of additional equipment operating leases entered into subsequent to
the third quarter of 2000.

Other Field Expenses

     Other field expenses, which include repairs and maintenance, equipment
service contracts, utilities and communication costs, increased $1,201,000 or
11.1% in the three months ended September 30, 2001 to $12,001,000 from
$10,800,000 for the three months ended September 30, 2000. As a percentage of
service fee revenues, these costs remained relatively constant 17.4% and 17.3%
in 2001 and 2000, respectively.

Bad Debt Expense

     Bad debt expense increased $1,003,000 or 18.8% for the three months ended
September 30, 2001 to $6,342,000 from $5,339,000 for the three months ended
September 30, 2000. This increase is primarily attributable to the increase in
revenue from contracted radiology practices and diagnostic imaging centers. As a
percentage of such revenues, bad debt expense was 6.7% and 6.1% in 2001 and
2000, respectively. As a percentage of service fee revenues, these costs were
9.2% and 8.5% in 2001 and 2000, respectively.

Corporate General and Administrative

     Corporate general and administrative expenses increased $1,725,000 or 62.0%
for the three months ended September 30, 2001 to $4,507,000 from $2,782,000 for
the three months ended September 30, 2000. As a percentage of service fee
revenues, these costs were 6.5% and 4.5% in 2001 and 2000, respectively. During
the three months ended September 30, 2001 we recorded a $1,000,000 one-time
charge for transaction costs related to the termination of a merger. The
increased expense is also partially due to additional costs incurred for the
further development of our infrastructure at the corporate office.



                                       10


Depreciation and Amortization

     Depreciation and amortization increased $307,000 or 5.6% for the three
months ended September 30, 2001 to $5,829,000 from $5,522,000 for the three
months ended September 30, 2000.

Interest Expense, net

     Interest expense, net decreased $990,000 or 21.6% for the three months
ended September 30, 2001 to $3,593,000 from $4,583,000 for the three months
ended September 30, 2000. The decrease is a result of the declining level of
debt outstanding and lower interest rates.

Income Taxes

     Our effective income tax rate for the three months ended September 30, 2001
and 2000 was 40.0%.

Net Income

     As a result of the foregoing factors, we generated net income of $3,782,000
for the three months ended September 30, 2001, or diluted income per share of
$0.18 on 22,817,000 shares outstanding, compared to net income of $4,246,000 for
the three months ended September 30, 2000, or diluted income per share of $0.20
on 22,143,000 shares outstanding.

NINE MONTHS ENDED SEPTEMBER 30, 2001 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
2000

Service Fee Revenues

     Service fee revenues increased $19,805,000 or 10.8% for the nine months
ended September 30, 2001 to $203,322,000 from $183,517,000 for the nine months
ended September 30, 2000. The increase is primarily attributable to an increase
in volume. In addition, the increase in service fee revenues is attributable to
the additional imaging centers of Questar, which were acquired, developed and
matured during the latter part of fiscal year 2000.

Field Salaries and Benefits

     Salaries and benefits increased $7,716,000 or 16.0% for the nine months
ended September 30, 2001 to $55,798,000 from $48,082,000 for the nine months
ended September 30, 2000. As a percentage of service fee revenues, these costs
were 27.4% and 26.2% in 2001 and 2000, respectively. The increase is partially
due to the additional imaging centers of Questar, which were acquired, developed
and matured during the latter part of fiscal year 2000. In addition, increased
benefit costs, as well as some effect of increased wage costs, primarily
technologists, experienced in certain markets, contributed to the higher
salaries and benefits.

Field Supplies

     Supplies increased $2,384,000 or 24.6% for the nine months ended September
30, 2001 to $12,082,000 from $9,698,000 for the nine months ended September 30,
2000. As a percentage of service fee revenues, these costs were 5.9% and 5.3% in
2001 and 2000, respectively. The increase in supplies is primarily attributable
to an increase in volume of specialty procedures. These procedures require
supplies with higher unit costs than typically required for other types of
imaging procedures.

Field Rent and Lease Expense

     Rent and lease expense increased $3,154,000 or 14.2% for the nine months
ended September 30, 2001 to $25,405,000 from $22,251,000 for the nine months
ended September 30, 2000. As a percentage of service fee revenues, these costs
were 12.5% and 12.1% in 2001 and 2000, respectively. The increase is primarily
the result of the additional equipment operating leases entered into subsequent
to the third quarter of 2000.



                                       11


Other Field Expenses

     Other field expenses, which include repairs and maintenance, equipment
service contracts, utilities and communication costs, increased $3,967,000 or
12.8% in the nine months ended September 30, 2001 to $34,925,000 from
$30,958,000 for the nine months ended September 30, 2000. As a percentage of
service fee revenues, these costs were 17.2% and 16.9% in 2001 and 2000,
respectively. The increase is a result of costs associated with the increased
service fee revenues from existing imaging centers as well as the additional
imaging centers of Questar, which were acquired, developed and matured during
the latter part of fiscal year 2000.

Bad Debt Expense

     Bad debt expense increased $3,098,000 or 19.4% for the nine months ended
September 30, 2001 to $19,074,000 from $15,976,000 for the nine months ended
September 30, 2000. This increase is primarily attributable to the increase in
revenue from contracted radiology practices and diagnostic imaging centers. As a
percentage of such revenues bad debt expense was 6.7% and 6.2% in 2001 and 2000,
respectively. As a percentage of service fee revenues, these costs were 9.4% and
8.7% in 2001 and 2000, respectively.

Corporate General and Administrative

     Corporate general and administrative expenses increased $2,685,000 or 32.2%
for the nine months ended September 30, 2001 to $11,017,000 from $8,332,000 for
the nine months ended September 30, 2000. The increase is primarily the result
of a $1,000,000 one-time charge for transaction costs related to the termination
of a merger. The increased expense is also partially due to additional costs
incurred for the further development of our infrastructure at the corporate
office. As a percentage of service fee revenues, these costs were 5.4% and 4.5%
in 2001 and 2000, respectively.

Depreciation and Amortization

     Depreciation and amortization increased $865,000 or 5.3% for the nine
months ended September 30, 2001 to $17,295,000 from $16,430,000 for the nine
months ended September 30, 2000.

Interest Expense, net

     Interest expense, net decreased $1,006,000 for the nine months ended
September 30, 2001 to $12,095,000 from $13,101,000 for the nine months ended
September 30, 2000. The decrease is a result of the declining level of debt
outstanding and lower interest rates.

Income Taxes

     Our effective tax rate for the nine months ended September 30, 2001 and
2000 was 40%.

Net Income

     As a result of the foregoing factors, we generated net income of
$11,232,000 for the nine months ended September 30, 2001, or diluted income per
share of $0.54 on 22,336,000 shares outstanding, compared to net income of
$12,702,000 for the nine months ended September 30, 2000, or diluted income per
share of $0.61 on 22,098,000 shares outstanding.


LIQUIDITY AND CAPITAL RESOURCES

     Net cash provided by operations for the nine months ended September 30,
2001 and 2000 was $30,089,000 and $10,349,000, respectively. The increase in the
cash provided by operations for the nine months ended September 30, 2001
compared to the nine months ended September 30, 2000 was primarily due to the

were $4,586,000 and $12,188,000, respectively. During the nine months ended
September 30, 2000, we invested $9,788,000 for acquisitions.

     Net cash flows used in financing activities were $26,187,000 for the nine
months ended September 30, 2001. The outstanding borrowings under the credit
facility were reduced by $19,416,000 for the nine months ended September 30,
2001. At September 30, 2001, we had outstanding borrowings of $137,584,000 under
the credit facility and an additional $37,431,000 outstanding under other credit
arrangements. Financing costs of $2,961,000 were incurred during the nine months
ended September 30, 2001 associated with the March 2001 amendment to the bank
credit facility. Net cash flows from financing activities for the nine months
ended September 30, 2000 were $10,584,000. Borrowings under the credit facility
for the nine months ended September 30, 2000 were used for the development of
centers within Questar, purchases of equipment and capital improvements, as well
as, working capital needs.

     On March 30, 2001, the bank credit facility was amended. Under the terms of
the amended credit facility, the $160,000,000 of borrowings consist of a
$100,000,000 Term Loan and a $60,000,000 revolving credit facility, including a
$5,000,000 Swing Line Facility. Under the new amendment, on June 29, 2001 and
September 28, 2001, we made $4,000,000 scheduled principal installment payments.
Scheduled principal installments for the fiscal year ended 2001 have been
reduced from $47,100,000 under the prior amended agreement to $12,000,000 under
the new amendment. Scheduled principal installments through September 30, 2002
consist of four quarterly installments as follows: 1) $4,000,000 on December 31,
2001, 2) $6,000,000 on March 31, 2002, 3) $9,000,000 on June 30, 2002 and 4)
$9,000,000 on September 30, 2002. Each of the facilities will terminate on
November 26, 2003. The interest rate is (i) an adjusted LIBOR rate, plus an
applicable margin which can vary from 3.00% to 4.00% dependent on certain
financial ratios or (ii) the prime rate, plus an applicable margin which can
vary from 2.00% to 3.00%. In each case, the applicable margin varies based on
financial ratios maintained by us. The credit facility includes certain
restrictive covenants including prohibitions on the payment of dividends,
limitations on capital expenditures and the maintenance of certain financial
ratios (including minimum fixed charge coverage ratio and maximum leverage
ratio, as defined). At September 30, 2001, we were in compliance with the
covenants under the credit facility's restrictive covenants. Borrowings under
the credit facility are secured by all service agreements, which we are, or
becomes a party to, a pledge of the stock of our subsidiaries, and all of our
wholly-owned subsidiaries' assets.

     We have a $23,824,263 convertible junior subordinated note, which matures
July 31, 2009, and bears interest, payable quarterly in cash or payment in kind
securities, at an annual rate of 8.0%. At August 1, 2001 the convertible junior
subordinated note was convertible into Radiologix's common stock at the price of
$7.52 per share. If by August 1, 2002 or August 1, 2003 the closing price of
Radiologix's common stock has not exceeded $7.52 for 45 of the 60 days of the
determination period, the interest rate will be increased to 8.25% and 8.5%,
respectively.

     Our ability to accomplish its goals and to execute its business strategy
depends on our continued ability to access capital on appropriate terms. Our
growth could be limited and its existing operations impaired unless it is able
to obtain additional capital through subsequent debt or equity financings. There
can be no assurance that borrowing capacity under the credit facility will be
available to us when needed or that we will be able to obtain additional
financing or that, if available, such financing will be on terms acceptable to
us. As a result, there can be no assurance that we will be able to implement its
business strategy successfully. However, management believes that cash flow from
operations and other available sources of liquidity will be sufficient to fund
our operations for at least the next 12 to 18 months.
