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 March 31, 2007 are not
necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2007. For further information, refer to the financial statements and footnotes thereto included in the Companys Annual Report on Form 10-KSB for
the fiscal year ended December 31, 2006 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. 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 nine months of 2007 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 does not expect to have any current source of revenues and has no operations. However, management believes that its cash balance as of March 31, 2007 of approximately $3.5 million is sufficient to fund its current cash flow requirements
through at least the next twelve months.

NOTE B -- STOCK OPTIONS:

Pursuant to the Companys 1991 Qualified Stock Option and 1991 Non-Qualified Stock Option Plans, as amended (the 1991 Plan), the Company was authorized to grant options to purchase up to (i) 280,000 shares
of Common Stock to its officers and key employees, at a price not less than the fair market value per share of Common Stock on the date of grant; and (ii) 120,000 shares of Common Stock to its directors, officers, key employees and others who
rendered services to the Company at such price as fixed by the Compensation and Stock Option Committee. Options granted under the 1991 Plan generally vest to the respective option holders at the rate of 20% per year commencing on the first
anniversary date of the grant. No new grants may be made under the 1991 Plan.

The Companys 1993 Non-Employee Director Stock Option Plan allows the Company to grant options to purchase up to 70,000 shares of Common Stock. Each non-employee director is to be granted options to purchase: (i) 2,000
shares of Common Stock upon initial appointment as a director of the Company; and (ii) an additional 1,200 shares, in recurring annual increments, at a price equal to the fair market value per share of Common Stock on the date of grant. Options
under the Non-Employee Director Plan vest to the respective option holder after one year and have a term of ten years. No new grants may be made under the 1993 Plan.

The Companys 1996 Stock Option Plan authorizes the grant of both incentive (ISO) and non-qualified stock options up to a maximum of 335,000 shares of the Companys Common Stock to employees (including
officers and directors who are employees) of and consultants to the Company. The exercise price, term and vesting provision of each option grant is fixed by the Compensation and Stock Option Committee with the provision that the exercise price of an
ISO may not be less than the fair market value of the Companys Common Stock on the date of grant, and the term of an ISO may not exceed ten years. The Company has not granted any options under this plan during the three months ended March 31,
2007 and year ended Decemner 31, 2006.

Commencing January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123R, Share Based Payment (SFAS 123R), which requires all share-based payments, including grants of
stock options, to be recognized in the income statement as an operating expense, based on their fair values.

---



The Company has applied the modified prospective method in adopting SFAS 123R. Accordingly, periods prior to adoption have not been restated. Under the modified prospective method, awards that were granted, modified, or
settled on or after January 1, 2006 are measured and accounted for in accordance with SFAS 123R. Unvested equity-classified awards that were granted prior to January 1, 2006 will continue to be accounted for in accordance with SFAS 123, except that
all awards are recognized in the results of operations over the remaining vesting periods. The impact of forfeitures that may occur prior to vesting is also estimated and considered in the amount recognized. In addition, the realization of tax
benefits in excess of amounts recognized for financial reporting purposes will be recognized as a financing activity in accordance with SFAS 123R.

No tax benefits were attributed to the stock-based compensation expense because a valuation allowance was maintained for substantially all net deferred tax assets. We elected to adopt the alternative method of calculating
the historical pool of windfall tax benefits as permitted by FASB Staff Position (FSP) No. SFAS 123R-3, Transition Election Related to Accounting for the Tax Effects of Share-Based Payment Awards. This is a simplified method to determine
the pool of windfall tax benefits that is used in determining the tax effects of stock compensation in the results of operations and cash flow reporting for awards that were outstanding as of the adoption of SFAS 123R.

The following summarizes the activity of the Companys stock options for the three months ended March 31, 2007.

The Company did not grant any options during the three months period ended March 31, 2007. Stock option compensation expense was $0 for the three months ended March 31, 2007.

As of March 31, 2007 and December 31, 2006 1,000 stock options with $0.99 weighted average exercise price per share were non vested and none of the non vested stock options were granted, canceled or expired and vested.

As of March 31, 2007, there was $1,000 of total unrecognized compensation cost related to non vested share-based compensation arrangements granted under existing stock option plans.  This cost is expected to be
recognized over a weighted-average period of 0.5 years. No share options vested during the three months ended March 31, 2007.

NOTE C -- CONTINGENCIES:

Legal proceedings: The Company is not currently a party to any litigation. However, from time to time, the Company could be subject to involvement in legal actions and claims, which
management believes will be resolved without a material adverse effect on the Companys business, financial condition or results of operations.

NOTE D  INCOME PER SHARE:

The calculation of basic and diluted income per share is as follows (in 000s, except per share amounts):

Outstanding stock options of 112,800 at March 31, 2007 and 174,600 at March 31, 2006, were excluded from the computation of diluted earnings per share because their effect was anti-dilutive.

NOTE E  OTHER EVENTS

The Company adopted Financial Standards Board Interpretation No. 48 Accounting for Uncertainty in Income Taxes (FIN 48) an
interpretation of FASB Statement 109 (SFAS 109) on January 1, 2007. As a result of the implementation of FIN 48, we recognized no
material adjustment in the liability for unrecognized tax benefits. At the adoption date of January 1, 2007, we had $10,082 of
unrecognized tax benefits, all of which would affect our effective tax rate if recognized. At March 31, 2007, we have $10,082 of
unrecognized tax benefits.

We recognize interest and penalties related to uncertain tax positions in general and administrative expense. As of March 31, 2007,
we have not recorded any provisions for accrued interest and penalties related to uncertain tax positions.

Tax years 2000-2006 remain open to examination by the major taxing jurisdictions to which we are subject.

Item 2.              Managements Discussion and Analysis or 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). 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 2005 and 2004 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 nine months of 2006 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 March 31, 2007 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.

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.
