                   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. 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, 2004. 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 three month and nine month periods
ended September 30, 2005 are not necessarily indicative of the results that may
be expected for the year ending December 31, 2005.


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. 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.

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.

Certain reclassifications have been made to the consolidated statements of cash
flows to conform with the current presentation.

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 September 30, 2005 and for the
three month 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.


                                        7

PRINCIPLES OF CONSOLIDATION (cont.)

The Company has accumulated a deficit since reentering the development stage, on
January 1, 2000, of $566,062 through September 30, 2005. 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
September 30, 2005, 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

In December 2004, the Financial Accounting Standards Board issued SFAS No. 123
(revised 2004), "Share-Based Payment". SFAS 123 (revised 2004) requires
companies to recognize in the statement of operations the grant-date fair value
of stock options and other equity-based compensation. That cost will be
recognized over the period during which an employee is required to provide
service in exchange for the award, usually the vesting period. Subsequent
changes in fair value during the requisite service period, measured at each
reporting date, will be recognized as compensation cost over that period. In
April 2005, the SEC extended the effective date for SFAS No. 123 (revised 2004)
for public companies, to the beginning of a registrant's next fiscal year that
begins after June 15, 2005. The Company will be required to adopt SFAS No. 123
(revised 2004) in its first quarter of fiscal 2006. Adoption of this SFAS is not
expected to have a material impact on the Company's consolidated financial
condition or results of operations.

NOTE 3 - RELATED PARTY TRANSACTIONS

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 25, 2005, the Board of Directors approved the renewal of the Mergers
and Acquisitions Advisory Agreement (the "M&A Advisory Agreement") between the
Company and Catalyst Financial LLC ("Catalyst") for a period of three (3) years
commencing on April 1, 2005 and modified the M&A Advisory Agreement 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 March 25, 2005, the Company issued an option to purchase 10,000 shares of the
Company's common stock at the purchase price of $1.16, which was 110% percent of
the closing bid price on March 25, 2005, to Leonard Hagan one of the Company's
independent directors, for his services to the Company. On March 25, 2005, the
Company issued an option to purchase 10,000 shares of the Company's common stock
at the purchase price of $1.16, which was 110% percent of the closing bid price
on March 25, 2005, to Kenneth Schwartz one of the Company's independent
directors, for his services to the Company. Such options are exercisable for a
period of 5 years commencing on March 25, 2005. On March 25, 2005, the Company
issued to Steven N. Bronson, the Company's President, an option to purchase
100,000 shares of the Company's common stock at the purchase price of $1.16,
which was 110% percent of the closing bid price on March 25, 2005. All of the
above described options are exercisable for a period of 5 years and resulted in
no expense to the Company.

Since January 5, 2004, for its principal office the Company is using a portion
of the premises occupied by Catalyst Financial LLC, located at 100 Mill Plain
Road, Danbury, Connecticut 06811. Steven N. Bronson, the President of the
Company, is the principal and owner of Catalyst Financial LLC. Catalyst
Financial LLC has agreed to waive the payment of any rent by the Company for use
of the offices. The Company has not paid any rent for its principal office for
the three month and nine month periods ended September 30, 2005 and 2004.

Item 2.  Management Discussion and Analysis or Plan of Operation

         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, 2004.

         Ridgefield Acquisition Corp. ("RAC" or the "Company") was incorporated
as a Colorado corporation on October 13, 1983. 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, is 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.

         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 have
been written off by the Company. The Company has 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 September 30, 2005 and 2004 and the
period from January 1, 2000 through September 30, 2005, the Company has earned
no revenues other than interest income from cash 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 requirement of state law 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.

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

         Following the sale of substantially all of the Company's assets in
1999, 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 for microdissection. The Company filed a patent
application in February 1998, to protect certain features of the system and
method of the micro-robotic device. However, due to the inability of the Company
to complete the micro-robotic device, the Company determined that it would cease
development of the micro-robotic device and, as of June 30, 2000, the
capitalized costs related to the patent underlying the micro-robotic device have
been written off by the Company.

         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 (the "Subsidiary"). A copy of the Articles of Incorporation
of Bio-Medical Automation, Inc. a Nevada corporation are attached as an Exhibit
to the Company's Current Report on Form 8-K filed on March 7, 2003 which is
incorporated herein by reference. The Board of Directors of the Company has
authorized management of the Company to transfer the Patent to the Subsidiary in
exchange for 5,000,000 shares of the common stock of the Subsidiary. The
transfer of the Patent to the Subsidiary became effective in the quarter ended
June 30, 2003. The Company plans to develop and exploit the Patent through the
Subsidiary. There can be no assurances that the Subsidiary will successfully
develop and/or exploit the technology covered by the Patent.


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.

                                       11
<PAGE>

         In furtherance of the Company's investment strategy the Company opened
a brokerage account with Catalyst Financial LLC ("Catalyst"), a broker-dealer
registered with the U.S. Securities and Exchange Commission and a member in good
standing with the National Association of Securities Dealers, Inc. Catalyst is
owned and controlled by Steven N. Bronson, the Company's President. Catalyst has
agreed to charge the Company commissions of no more that $.02 per share with a
minimum of $75 per trade on securities transactions. The Board approved the
commission structure to be charged by Catalyst. Mr. Bronson abstained from
voting on all Board resolutions concerning the Company's investment strategy and
the Company's arrangements with Catalyst.

          The Company has investments in a brokerage account with Catalyst. As
of September 30, 2005, the Company owned securities valued at $81,200. Such
securities had an accumulated other comprehensive loss totaling $6,834 at
September 30, 2005. The Company's investment in securities is subject to all of
the risks associated with equity investing, including a loss of monies invested.
There can be no assurance that the Company will be able to obtain a profitable
return on its investments.


Results of Operations
---------------------

       For the three months ended September 30, 2005, the Company has earned
revenues, from interest income of $988 and realized gains of $6,382. For the
same period the Company incurred general and administrative expenses of $11,716
resulting in a net loss from operations equal to $4,346. General and
administrative expenses were and have been directed to maintaining the Company's
status as a public company, including (without limitation) filing reports with
the Securities and Exchange Commission. On September 30, 2005, the Company had
invested $81,200 in accordance with its Investment Strategy. Such securities had
an unrealized gain of $19,067 for the three months ended September 30, 2005.

     For the nine month periods ended September 30, 2005 and 2004, the Company
had revenues, from interest income of $2,729 and $625, respectively and realized
gains of $6,382 and $11,454, respectively. Operating expenses for the nine month
periods ended September 30, 2005 and 2004 were $34,817 and $56,562,
respectively. For the nine month periods ended September 30, 2005 and 2004, the
Company had net operating losses of $25,706 and $44,483 respectively.


Liquidity and Capital Resources
-------------------------------

         During the nine months ended September 30, 2005, the Company satisfied
its working capital needs from cash on hand and cash generated from interest
income during the year. As of September 30, 2005, the Company had on hand cash
in the amount of $191,579.

       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
