                    CELLULAR TECHNICAL SERVICES COMPANY, INC.
                         
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE A -- BASIS OF PRESENTATION AND LIQUIDITY:

The accompanying unaudited condensed consolidated financial statements of
Cellular Technical Services Company, Inc. ("CTS" or the "Company") have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-QSB. Accordingly,
they do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the opinion
of management, all adjustments (consisting of normal recurring accruals)
considered necessary for a fair presentation have been included. The operating
results for the three month period ended June 30, 2005 are not necessarily
indicative of the results that may be expected for the fiscal year ending
December 31, 2005. For further information, refer to the financial statements
and footnotes thereto included in the Company's Annual Report on Form 10-KSB for
the year ended December 31, 2004 and in the Company's other filings with the
Securities and Exchange Commission. Unless the context otherwise requires, all
references to "CTS" or the "Company" herein include Cellular Technical Services
Company, Inc. and any entity over which it has or shares operational control.

CTS has no current business. Management currently has no plan to liquidate the
Company and distribute the remaining assets to stockholders. As of early 2004,
the Company may be considered as a dormant enterprise in accordance with
Statement of Financial Accounting Standards No. 7. The Company has been and will
be evaluating alternative businesses and acquisitions. There is no assurance
that such alternative businesses and acquisitions can be accomplished before CTS
spends all of its remaining cash balances, that CTS will be able to raise money
at acceptable terms, if at all, to fund the acquisitions and/or the operating
activities of the businesses it may acquire, and that the acquired businesses
will represent viable business strategies and/or will be consistent with the
expectations and risk profiles of CTS' stockholders.

Based on management plans, these financial statements have been prepared under
the "going concern" assumption which presumes that the Company will continue its
existence.

Management expects that during the remaining six months of 2005 the Company will
incur costs of approximately $0.30 million, primarily related to costs of
maintaining the business as a public entity and insurance. The Company does not
expect to have any current source of revenues and has de minimis operations.
Accordingly, management believes that its cash balances as of June 30, 2005 of
approximately $3.5 million are sufficient to fund its current cash flow
requirements through at least the next twelve months.

NOTE B -- STOCK OPTIONS

As provided for by FAS No. 123 - Accounting for Stock-Based Compensation, the
Company has chosen to measure stock-based compensation cost under the
intrinsic-value method prescribed under Accounting Principles Board Opinion No.
25 and has adopted only the disclosure provisions of FAS 123. As the Company
issues options with exercise prices equal to market value on the date of grant,
compensation expense is not recognized. Stock compensation expense for options
granted to non-employees has been determined in accordance with FAS 123 and
Emerging Issues Task Force ("EITF") Issue No. 96-18 as the fair value of the
consideration received or the fair value of the equity instruments issued,
whichever is more reliably measured. The fair value of options granted to
non-employees is periodically re-measured as the underlying options vest.

The pro forma information regarding net income (loss) and earnings (loss) per
share is required by FAS 123, which has been updated by FAS No. 148 - Accounting
for Stock-Based Compensation - Transition and Disclosure, and has been
determined as if the Company had accounted for its employee stock options under
the fair value method of those statements. In that regard, the fair value for
options granted during the period June 30, 2004 was estimated at the date of
grant using a Black-Scholes option-pricing model with the following
weighted-average assumptions: (No options were granted during the period ended
June 30, 2005)

NOTE C -- CONTINGENCIES:

Legal proceedings: From time to time, the Company is involved with or could be
subject to involvement with legal actions and claims which arise in the ordinary
course of business which management believes will be resolved without a material
adverse effect on the Company's business, financial condition or results of
operations. On October 25, 2001, New England Telecom, Inc. and Paul Gregory, a
former employee, filed a claim in the Superior Court of Massachusetts (the
"Court") against the Company its Chairman, and Isis Tele-Communications, Inc
("Isis"), a majority owned subsidiary of the Company, alleging, among other
things, that the Company breached a purchase agreement and a related employment
contract. The agreement included a two-year earn-out with a maximum contingent
total payout of $1.5 million. During December 2004, the Court dismissed all
claims against the Company and its Chairman. During May 2005, this case was
settled out of court by payment of a nominal sum to Mr. Gregory. The expense has
been included in General and Administrative Expenses on the Statement of
Operations.

Outstanding stock options of 192,800 and 191,065 at June 30, 2005 and 2004,
respectively, were excluded from the computation of diluted earnings per share
because their effect was anti-dilutive.

NOTE E - OTHER EVENTS

On April 12, 2005 the Company entered into a Securities Purchase Agreement (the
"Agreement") with Frost Gamma Investments Trust (the "Frost Trust"), Dr. Jane
Hsiao and Richard C. Pfenniger, Jr., among others. Pursuant to the Agreement,
the Company sold an aggregate of 2,100,000 shares of the Common Stock of the
Company. The purchase price for the sale of the Common Stock was $0.75 per share
in cash for an aggregate price of $1,575,000. The Company's cost for this
transaction was $15,000, resulting in an increase in Cash of $1,560,000.
Pursuant to the Agreement, the Frost Trust, Dr. Hsiao and Mr. Pfenniger
purchased 1,400,000 shares, 200,000 shares and 100,000 shares, respectively, of

Item 2. Management's Plan of Operations

Special Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-QSB contains certain forward-looking statements
within the meaning of the Private Securities Litigation Reform Act of 1995 that
reflect the Company's views with respect to future events and financial
performance. The Company uses words and phrases such as "anticipate," "expect,"
"intend," "the Company believes," "future," and similar words and phrases to
identify forward-looking statements. Reliance should not be placed on these
forward-looking statements. These forward-looking statements are based on
current expectations and are subject to risks, uncertainties and assumptions
that could cause, or contribute to causing, actual results to differ materially
from those expressed or implied in the applicable statements. Readers should pay
particular attention to the descriptions of risks and uncertainties described in
this report and in the Company's other filings with the Securities and Exchange
Commission. All forward-looking statements included in this report are based on
information available to the Company on the date of this report. The Company
assumes no obligation or duty to update any such forward-looking statements.


The Company files its periodic reports with the SEC in compliance with the
"small business issuer" provisions of Regulation S-B, under the Securities
Exchange Act of 1934 (the "Exchange Act"). Prior to the quarter ended March 31,
2004, the Company had filed its periodic reports under Regulation S-K and
Regulation S-X, under the Exchange Act. Generally, a Small Business Issuer
cannot file under Regulation S-B if its annual revenues or public float exceed
$25.0 million for two consecutive years. The Company qualifies as a Regulation
S-B filer since its annual revenues for both 2004 and 2003 were less than $25.0
million and its public float has not exceeded $25.0 million. Regulation S-B is
tailored for the small business issuer, and although it requires accurate and
complete disclosure, it does not require certain specific disclosures which are
required under Regulation S-K and Regulation S-X. 

Management expects that during the last six months of 2005 the Company will 
incur costs of approximately $0.3 million, primarily related to costs of 
maintaining the business as a public entity and insurance. The Company is not 
expected to have any significant revenues or operations. There can be no 
assurance that the Company's operations will be profitable on a quarterly or 
annual basis in the future or that revenue levels can be enhanced. Existing 
revenue levels should not be considered indicative of future operating results.
Accordingly, subject to a potential acquisition or other investment, management
believes that its cash balances as of June 30, 2005 are sufficient to fund its 
current cash flow requirements through at least the next twelve months; 
however, unanticipated changes may require additional financing.

The Company has no current business. It is not engaged in any planned product
research and development and it does not anticipate doing so in the future. The
Company has disposed of all of its equipment, and has one part time employee.
                
On April 12, 2005 the Company entered into a Securities Purchase Agreement (the
"Agreement") with Frost Gamma Investments Trust (the "Frost Trust"), Dr. Jane
Hsiao and Richard C. Pfenniger, Jr., among others. Pursuant to the Agreement,
the Company sold an aggregate of 2,100,000 shares of the Common Stock of the
Company. The purchase price for the sale of the Common Stock was $0.75 per share
in cash for an aggregate price of $1,575,000. The Company's cost for this
transaction was $15,000, resulting in an increase in Cash of $1,560,000.
Pursuant to the Agreement, the Frost Trust, Dr. Hsiao and Mr. Pfenniger
purchased 1,400,000 shares, 200,000 shares and 100,000 shares, respectively, of
Common Stock. Dr. Phillip Frost controls the Frost Trust. Dr. Frost, Dr. Hsiao
and Mr. Pfenniger were elected to the board of directors of the Company pursuant
to the provisions of the Agreement.

Item 3. Controls and Procedures

The Company maintains a system of disclosure controls and procedures that is
designed to provide reasonable assurance that information, which is required to
be disclosed by the Company in the reports that it files or submits under the
Exchange Act, is accumulated and communicated to management in a timely manner.
The Company's Chief Executive Officer and Chief Financial Officer have evaluated
this system of disclosure controls and procedures as of the end of the period
covered by this quarterly report, and believe that the system is operating
effectively to ensure appropriate disclosure. There have been no changes in the
Company's internal control over financial reporting during the most recent
fiscal quarter that have materially affected, or are reasonably likely to
materially affect, the Company's internal control over financial reporting.
