                   RIDGEFIELD ACQUISITION CORP. AND SUBSIDIARY
                          (A Development Stage Company)
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

         The unaudited financial statements included herein were prepared from
the records of the Company in accordance with accounting principles generally
accepted in the United States of America and reflect all adjustments which are,
in the opinion of management, necessary to provide a fair statement of the
results of operations and financial position for the interim periods March 31,
2007 and 2006 and cumulative amounts from January 1, 2000 through March 31,
2007. Such financial statements generally conform to the presentation reflected
in the Company's Form 10-KSB filed with the Securities and Exchange Commission
for the year ended December 31, 2006. The current interim period reported herein
should be read in conjunction with the Company's Form 10-KSB subject to
independent audit at the end of the year.

         The results of operations for the interim periods are not necessarily
indicative of the results that may be expected for the fiscal year.


NOTE 1 - ORGANIZATION AND BASIS OF PRESENTATION

Ridgefield Acquisition Corp. (the "Company") was incorporated under the laws of
the State of Colorado on October 13, 1983. Effective June 23, 2006, the Company
was reincorporated under the laws of the State of Nevada through the merger of
the Company with a wholly owned subsidiary of the Company. The Company had been
engaged in the design, manufacture and marketing of robotic workstations for the
electronics industry, including routing and depaneling workstations
predominately to entities in North America and the Pacific Rim. In November 1998
the Company entered into an Asset Purchase Agreement (the "JOT Agreement") with
JOT Automation, Inc. (JOT) a wholly owned Texas subsidiary of JOT Automation
Group OYJ, a Finnish corporation. Pursuant to the agreement, the Company sold
JOT all of its assets relating to its depaneling and routing business in
exchange for $920,000 and the assumption of the operating liabilities related to
the Company's business assets. The sale was completed on March 9, 1999.

Subsequent to the sale to JOT, the Company's sole continuing operation was the
continuation of research and development activities on a prototype micro-robotic
device to manipulate organ tissues on an extremely small scale. The Company had
filed for a patent application for the device. As of December 31, 1999, the
Company's research and development activities for the device were suspended,
pending assessment of the economic benefit of continuing research and
development activities or sale of the patent, as well as assessment of other
corporate opportunities. In June 2000, the Company decided not to pursue further
development or sale of the proto-type device and has written-off the associated
patent costs.

                                        6

NOTE 1 - ORGANIZATION AND BASIS OF PRESENTATION (Continued)

On January 31, 2006, the Board of Directors of the Company directed the officers
of the Company to take and approve certain corporate action with respect to the
Company's wholly owned subsidiary Bio-Medical Automation, Inc., a Nevada
corporation (the "Subsidiary"). Those actions included the appointment of Steven
N. Bronson, Alan Rosenberg and Louis Meade to be on the Board of Directors of
the Subsidiary for a term of one year or until their successor is appointed and
duly qualified, the appointment of Steven N. Bronson as the president, treasurer
and secretary of the Subsidiary, the opening of a bank account at Bank of
America or some other banking institution for the Subsidiary and the
ratification of the bylaws of the Subsidiary in the form that was presented to
the Board. Additionally, the Board of Directors authorized the officers of the
Company to deposit $50,000 of the Company's assets in the Subsidiary's bank
account. The Company took the foregoing action to further its plans to exploit
the Patent owned by the Subsidiary. Additionally, in furtherance of the
Company's plan to exploit the Patent, the Board of Directors of the Company
authorized the spin off of the Subsidiary to the Company's shareholders on a pro
rata basis, so that the Subsidiary may be better able to exploit the Patent, by
among other things being able to attract financing (See Note 6).


Commencing January 1, 2000, the Company is considered a development stage
company as defined by Statement of Financial Accounting Standards (SFAS) No.7,
as it has no principal operations or revenue from any source.


PRINCIPLES OF CONSOLIDATION

The consolidated financial statements of Ridgefield Acquisition Corp. include
the accounts of Bio-Medical Automation, Inc., its wholly owned subsidiary. All
inter-company transactions have been eliminated in consolidation.

The accompanying financials statements as of March 31, 2007 and for the three
and nine month periods then ended include the accounts of the Company and its
wholly owned subsidiary. All inter-company accounts and transactions have been
eliminated in consolidation.

The Company has accumulated a deficit since reentering the development stage of
$729,816 through March 31, 2007. In 1999, the Company sold all of its assets
relating to its historical line of business and in 2000 abandoned its research
and development efforts on a micro-robotic device. As of March 31, 2007, the
Company has no principal operations or revenue producing activities. The Company
is now pursuing an acquisition strategy whereby it is seeking to arrange for a
merger, acquisition or other business combination with a viable operating
entity.


Note 2 - NEW ACCOUNTING STANDARD

There are no new accounting standards that are expected to have a significant
impact on the Company.

                                        7
<PAGE>

Note 3 - INCOME TAXES

The Company adopted the provisions of FASB Interpretation No. 48, "Accounting
for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 9"
("FIN No. 48"), on January 1, 2007. FIN No. 48 requires that the impact of tax
positions be recognized in the financial statements if they are more likely than
not of being sustained upon examination, based on the technical merits of the
position. As discussed in the consolidated financial statements in the 2006 Form
10-KSB, the Company has a valuation allowance against the full amount of its net
deferred tax assets. The Company currently provides a valuation allowance
against deferred tax assets when it is more likely than not that some portion,
or all of its deferred tax assets, will not be realized. There was no impact to
the Company as a result of implementing FIN No. 48.

The Company is subject to U.S. federal income tax as well as income tax of
certain state jurisdictions. The Company has not been audited by the I.R.S. or
any states in connection with income taxes. The periods from inception -2006
remain open to examination by the I.R.S. and state authorities.

We recognize interest accrued related to unrecognized tax benefits in interest
expense. Penalties, if incurred, are recognized as a component of income tax
expense.

NOTE 4 - RELATED PARTY TRANSACTIONS

In November 2001, the Company entered into a Mergers and Acquisitions Advisory
Agreement with Catalyst Financial LLC ("Catalyst"), an entity whose owner and
principal is the President of the Company. Under the terms of the agreement,
Catalyst will earn a fee, as outlined in the agreement, in the event the Company
completes a merger. The agreement was for a three year period and terminated
November, 2004. On March 25, 2005, the Board of Directors approved the renewal
of the Mergers and Acquisitions Advisory Agreement (the "M&A Advisory
Agreement")for a period of three (3) years commencing on April 1, 2005. The M&A
Advisory Agreement was also modified to provide that Catalyst shall receive a
monthly retainer fee in the amount of $1,000 commencing on April 1, 2005 and
continuing throughout the term of the M&A Advisory Agreement. On January 31,
2006, the Board of Directors of the Company directed the officers of the Company
to amend the M&A Advisory Agreement to provide that the monthly retainer fee be
increased from $1,000 per month to $5,000 per month from February 1, 2006
through January 31, 2007. Thereafter, the Company shall pay a monthly fee in the
amount of $1,000 through March 1, 2008.

During 2003, the President was granted an option to purchase 150,000 shares of
the Company's common stock at an exercise price of 110% of the closing market
price as of the date of grant, for a period of five years. On March 25, 2005,
the Board of Directors renewed the President's employment agreement through
March 23, 2006 with the modification that the President will no longer receive
an annual salary of $48,000. The Board also agreed to pay the President's
accrued salary of $113,132 through the issuance of 107,745 shares at fair value
of the Company's common stock. On March 28, 2006, the Company entered into a new
employment agreement with Mr. Bronson, that provides Mr. Bronson will serve as
President of the Company without an annual salary.

Item 2.  Management Discussion and Analysis or Plan of Operation


Forward Looking Statements Disclosure
-------------------------------------

        This report on Form 10-QSB contains, in addition to historical
information, 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
(the "Exchange Act"). You can identify these forward-looking statements when you
see words such as "expect," "anticipate," "estimate," "may," "plans," "believe,"
and other similar expressions. These statements are not guarantees of future
performance and are subject to certain risks, uncertainties and assumptions that
are difficult to predict. Actual results could differ materially from those
projected in the forward-looking statements. Factors that could cause such a
difference include, but are not limited to, those discussed in the section
entitled "Factors Affecting Operating Results and Market Price of Stock,"
contained in the Company's Annual Report on Form 10-KSB for the year ended
December 31, 2006. Readers are cautioned not to place undo reliance on these
forward-looking statements, which speak only as of the date hereof. We undertake
no obligation to update any forward-looking statements.

        The following discussion and analysis provides information which the
Company's management believes to be relevant to an assessment and understanding
of the Company's results of operations and financial condition. This discussion
should be read together with the Company's financial statements and the notes to
financial statements, which are included in this report, as well as the
Company's Annual Report on Form 10-KSB for the year ended December 31, 2006.

        Ridgefield Acquisition Corp. (the "Company") was incorporated as a
Colorado corporation on October 13, 1983 under the name Ozo Diversified, Inc. On
June 23, 2006, the Company filed Articles of Merger with the Secretary of State
of the State of Nevada that effected the merger between the Company and a wholly
owned subsidiary formed under the laws of the State of Nevada ("RAC-NV"),
pursuant to a plan of merger, whereby RAC-NV was the surviving corporation. The
merger changed the domicile of the Company from the State of Colorado to the
State of Nevada. Furthermore, as a result of the plan of merger the Company is
authorized to issue 35,000,000 shares of capital stock consisting of 30,000,000
shares of common stock, $.001 par value per share and 5,000,000 shares of
preferred stock, $.01 par value per share.

        On March 9, 1999, the Company completed the sale of substantially all of
its assets to JOT Automation, Inc. (the "JOT Transaction"). As a result of the
JOT Transaction, the Company's historical business, the depaneling and routing
business, was considered to be a "discontinued operation" and, consequently,
provides no benefit to persons seeking to understand the Company's financial
condition or results of operations.

                                       10
<PAGE>

        Following the JOT Transaction the Company devoted its efforts to the
development of a prototype micro-robotic device (the "micro-robotic device") to
manipulate organic tissues on an extremely small scale. Due to the inability to
complete the micro-robotic device, the Company determined that it would cease
the development of the micro-robotic device and, as of June 30, 2000, the
capitalized costs related to the patent underlying the micro-robotic device were
written off by the Company. The Company never derived any revenues from the
micro-robotic device.

        Since July 2000, the Company has suspended all operations, except for
necessary administrative matters relating to the timely filing of periodic
reports as required by the Securities Exchange Act of 1934. Accordingly, during
the three month and nine month periods ended March 31, 2007 and 2006 and the
period from January 1, 2000 through March 31, 2007, the Company has earned no
revenues other than interest income and income from investments.


Acquisition Strategy
--------------------

        The Company is primarily engaged in seeking to arrange for a merger,
acquisition, business combination or other arrangement by and between the
Company and a viable operating entity. The Company has not identified a viable
operating entity and there can be no assurance that the Company will ever
successfully arrange for a merger, acquisition, business combination or other
arrangement.

        The Company anticipates that the selection of a business opportunity
will be a complex process and will involve a number of risks, because
potentially available business opportunities may occur in many different
industries and may be in various stages of development. Due in part to depressed
economic conditions in a number of geographic areas, rapid technological
advances being made in some industries and shortages of available capital,
management believes that there are numerous firms seeking either the limited
additional capital which the Company will have or the benefits of a publicly
traded corporation, or both. The perceived benefits of a publicly traded
corporation may include facilitating or improving the terms upon which
additional equity financing may be sought, providing liquidity for principal
shareholders, creating a means for providing incentive stock options or similar
benefits to key employees, and providing liquidity for all shareholders and
other factors.

        In some cases, management of the Company will have the authority to
effect acquisitions without submitting the proposal to the shareholders for
their consideration. In some instances, however, the proposed participation in a
business opportunity may be submitted to the shareholders for their
consideration, either voluntarily by the Board of Directors to seek the
shareholders' advice and consent, or because of a legal requirement to do so.

        In seeking to arrange a merger, acquisition, business combination or
other arrangement by and between the Company and a viable operating entity,
management's objective will be to obtain long-term capital appreciation for the
Company's shareholders. There can be no assurance that the Company will be able
to complete any merger, acquisition, business combination or other arrangement
by and between the Company and a viable operating entity.

        The Company may need additional funds in order to effectuate a merger,
acquisition or other arrangement by and between the Company and a viable
operating entity, although there is no assurance that the Company will be able
to obtain such additional funds, if needed. Even if the Company is able to
obtain additional funds there is no assurance that the Company will be able to
effectuate a merger, acquisition or other arrangement by and between the Company
and a viable operating entity.

                                       11

The Company's U.S. Patent
--------------------------

        On March 19, 2002, the Company was awarded United States Patent No. US
6,358,749 B1 for the "Automated System for Chromosome Microdissection and Method
of Using Same" (the "Patent").

        The Patent covers an automated system and method for microdissection of
samples such as chromosomes or other biological material, and in particular, it
relates to a robotic assisted microdissection system and method that
significantly reduces the time and skill needed for cellular and sub-cellular
dissections. Microdissection is defined as dissection under the microscope;
specifically: dissection of cells and tissues by means of fine needles that are
precisely manipulated by levers. The system and method covered by the Patent
attempts to provide reliability and ease of operation thereby making
microdissection widely available to laboratories. While the Company has never
derived any revenues from the micro-robotic device, the Company plans to attempt
to license or sell the technology covered by the Patent. There can be no
assurances that the Company will be able to successfully market the technology
covered by the Patent or that the Company will ever derive any revenues from the
Patent or the technology covered by the Patent.

        During the first quarter of 2003, the Board of Directors of the Company
authorized the formation of a wholly owned subsidiary of the Company for the
purposes of owning, developing and exploiting the Patent. On March 3, 2003, the
Company filed Articles of Incorporation with the Secretary of State of the State
of Nevada to form Bio-Medical Automation, Inc., a Nevada corporation wholly
owned by the Company ("Bio-Medical" or the "Subsidiary"). In May 2003, the
Company transferred the Patent to the Subsidiary in exchange for 5,000,000
shares of the common stock of the Subsidiary.

        On January 31, 2007, the Board of Directors of the Company, among other
things, duly appointed officers and directors for the Subsidiary. The following
table sets forth the name, age and position of each of the directors, executive
officers and significant employees of Bio-Medical as of March 31, 2007. Each
director will serve on the Board of Directors of the Subsidiary for a term of
one year or until their successor is appointed and duly qualified at the next
annual meeting of the Subsidiary's stockholders or until his or her successor
has been elected and qualified. The Subsidiary's executive officers are
appointed by, and serve at the discretion of, the Board of Directors.

Name                    Age     Position
------------------     -----    --------------------
Steven N. Bronson        41     Chairman, President, Treasurer and Secretary
Alan Rosenberg           36     Director
Louis Meade              50     Director

        The Subsidiary does not currently provide any compensation to its
officers or directors.

        In March 2006, the Company deposited $50,000 of the Company's assets
into the Subsidiary's bank account.

        The Company took the foregoing action to further its plans to exploit
the Patent owned by the Subsidiary. However, there can be no assurances that the
Subsidiary will successfully develop and/or exploit the technology covered by
the Patent.

        As of March 31, 2007, Bio-Medical had 45,000,000 shares of capital stock
authorized for issuance consisting of (1) 40,000,000 share of common stock par
value $.001 per share; and (2) 5,000,000 shares of preferred stock par value
$.01 per share. Bio-Medical has 1,140,773 shares of its common stock issued and
outstanding, all of which are owned by the Company. Bio-Medical has no shares of
preferred stock issued or outstanding. A copy of the Articles of Incorporation
and bylaws of Bio-Medical are attached to the Company's Annual Report on Form
10-KSB for the year ended December 31, 2005 as Exhibit 3.6 and Exhibit 3.7,
respectively, and such documents are incorporated herein by reference.

                                    12
<PAGE>

The Spin-Off of Bio-Medical
---------------------------

        In furtherance of the Company's plan to exploit the Patent, in April
2006, the Board of Directors of the Company authorized the spin-off of 100% of
the Company's wholly owned subsidiary Bio-Medical to the Company's shareholders
on a pro rata basis. On or about May 30, 2006, the Company mailed to its
shareholders of record as of April 28, 2006, an Information Statement containing
the information concerning the Company and the Spin Off called for by Regulation
14C under the Securities Exchange Act of 1934. The Information Statement on
Schedule 14C is incorporated herein by reference. To consummate the Spin-Off,
Bio-Medical was required to file a registration statement on Form 10-SB to
register all of the issued and outstanding shares of Bio-Medical.

         On April 27, 2007, the Board of Directors of the Company voted to
terminate the proposed spin-off of Bio-Medical, based on current market
conditions and the risks associated with the business prospects of Bio-Medical.


Investment Strategy
-------------------

        On August 25, 2003, the Board of Directors of the Company authorized the
Company to invest a portion of the Company's cash in marketable securities in an
effort to realize a greater rate of return than the Company is currently earning
in light of historically low interest rates. The Board directed that management
maintain at least $40,000 of the Company's cash in a federally insured bank or
money market account.

        The Company's future financial condition will be subject to: (1) its
ability to arrange for a merger, acquisition or a business combination with an
operating business on favorable terms that will result in profitability, or (2)
its ability to successfully develop and exploit the Patent. There can be no
assurance that the Company will be able to do so or, if it is able to do so,
that the transaction will be on favorable terms not resulting in an unreasonable
amount of dilution to the Company's existing shareholders.

        The Company may need additional funds in order to effectuate a merger,
acquisition or other arrangement by and between the Company and a viable
operating entity, although there is no assurance that the Company will be able
to obtain such additional funds, if needed. Even if the Company is able to
obtain additional funds there is no assurance that the Company will be able to
effectuate a merger, acquisition or other arrangement by and between the Company
and a viable operating entity.

conditions and the risks associated with the business prospects of Bio-Medical.
The Board of Directors of the Company had previously authorized the spin-off of
Bio-Medical, in April 2006, in an attempt to exploit the patent held by
Bio-Medical.
