                   RIDGEFIELD ACQUISITION CORP. AND SUBSIDIARY

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - ORGANIZATION AND BASIS OF PRESENTATION

     The unaudited condensed consolidated financial statements included herein
were prepared pursuant to the rules and regulations of the Securities and
Exchange Commission. Certain information and footnote disclosure normally
included in financial statements prepared in accordance with accounting
principles generally accepted in the United States of America have been
condensed or omitted pursuant to such rules and regulations. In the opinion of
management, disclosures made are adequate to make the information not
misleading. These condensed consolidated financial statements should be read in
conjunction with the financial statements and notes included in the Company's
Form 10-K for the year ended December 31, 2009.

     In the opinion of management, the interim data includes all normally
recurring adjustments, necessary for a fair presentation of the results for the
interim period. The results of operations for the interim periods are not
necessarily indicative of the results that may be expected for the fiscal year.


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 financial statements as of September 30, 2010 and for the three
and nine months then ended include the accounts of the Company and its
wholly-owned subsidiary.

As of September 30, 2010, the Company has no principal operations or revenue
from its operations. 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.


ASSETS AND LIABILITIES MEASURED AT FAIR VALUE

Fair value measurements should be determined based on the assumptions that
market participants would use in pricing the asset or liability. A fair value
hierarchy has been established that distinguishes between market participant
assumptions based on market data obtained from sources independent of the
reporting entity (observable inputs that are classified within Levels 1 and 2 of
the hierarchy) and the reporting entity's own assumptions about market
participant assumptions (unobservable inputs classified within Level 3 of the
hierarchy).


                                        6
<PAGE>

                   RIDGEFIELD ACQUISITION CORP. AND SUBSIDIARY

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


            ASSETS AND LIABILITIES MEASURED AT FAIR VALUE (continued)

Level 1 inputs utilize quoted prices (unadjusted) in active markets for
identical assets or liabilities that the Company has the ability to access.
Level 2 inputs are inputs other than quoted prices included in Level 1 that are
observable for the asset or liability, either directly or indirectly. Level 2
inputs may include quoted prices for similar assets and liabilities in active
markets, as well as inputs that are observable for the asset or liability (other
than quoted prices), such as interest rates, foreign exchange rates, and yield
curves that are observable at commonly quoted intervals. Level 3 inputs are
unobservable inputs for the asset or liability which are typically based on an
entity's own assumptions, as there is little, if any, related market activity.
In instances where the determination of the fair value measurement is based on
inputs from different levels of the fair value hierarchy, the level in the fair
value hierarchy within which the entire fair value measurement falls is based on
the lowest level input that is significant to the fair value measurement in its
entirety. The Company's assessment of the significance of a particular input to
the fair value measurement in its entirety requires judgment, and considers
factors specific to the asset liability.


NOTE 2 - GOING CONCERN

The accompanying consolidated financial statements have been prepared on the
basis of accounting principles applicable to a going concern which contemplates
the realization of assets and extinguishment of liabilities in the normal course
of business. As shown in the accompanying consolidated financial statements, the
Company has accumulated a deficit of $1,384,879 through September 30, 2010. As
of September 30, 2010, the Company has no principal operations or revenue
producing activities.

These factors indicate that the Company may be unable to continue in existence.
The Company's financial statements do not include any adjustments related to the
carrying value of assets or the amount and classification of liabilities that
might be necessary should the Company be unable to continue in existence. The
Company's ability to establish itself as a going concern is dependent on its
ability to merge with another entity or acquire revenue producing activities.


NOTE 3 - NEW ACCOUNTING STANDARDS

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

NOTE 4 - RELATED PARTY TRANSACTIONS

The Company occupies a portion of the premises occupied by BKF Capital Group,
Inc. at 225 N.E. Mizner Boulevard, Suite 400 Boca Raton, Florida 33432 on a
month to month basis for a monthly fee of $100 per month paid to BKF Capital
Group, Inc. Steven N. Bronson, the Company's president, is the president of BKF
Capital Group, Inc.

On March 28, 2006, the Company entered into an employment agreement with Mr.
Bronson, that provides Mr. Bronson will serve as President of the Company
without an annual salary.

Pursuant to the Consulting Agreement, dated June 6, 2008, between the Company
and Catalyst Financial, LLC, during the nine months ended September 30, 2010,
the Company issued Catalyst Financial 6,000 shares of the Company's common
stock. The agreement expired on January 31, 2010.

NOTE 5 - INVESTMENTS

Investments are classified as available for sale. Accordingly, the investments
are carried at fair value with unrealized gains and losses reported separately
in other comprehensive income. Realized gains and losses are calculated using
the original cost of those investments. On July 2, 2009 the Company purchased
50,000 shares of common stock of FCStone Group, Inc, at a price of $4.0015 a
share or $200,575. On October 1, 2009, the previously announced merger between
International Assets Holding Corporation ("IAAC") and FCStone was completed and
each outstanding share of FCStone was exchanged for .2950 shares of IAAC.
Accordingly, on October 1, 2009, the Company received 14,750 share of IAAC in
exchange for its 50,000 shares of FCStone. On March 10, 2010, the Company sold
4,750 shares of IAAC for gross proceeds of approximately $80,936. On April 21,
2010, the Company sold the remaining 10,000 shares of IAAC for gross proceeds of
approximately $162,121.

During January 2010 the Company sold its remaining shares of Argan, Inc. for
gross proceeds of $365,845 and thus the Company held no investments at September
30, 2010.

The valuation of such stock is based on quoted prices (unadjusted) and as a
result the investments were classified within Level 1 of the fair-value
hierarchy.

Money Market Funds          $893,140   $   --    $    --         $893,140

The Company does not have any fair value measurements within Level 2 or Level 3
of the fair value hierarchy as of September 30, 2010.


NOTE 7 - INCOME TAXES

The estimate of the effective tax rate is based on projections of income taxes
for the full fiscal year. The estimated expense for the period ended September
30, 2010 did not result in a recorded tax provision due to the availability of
net operating loss carryforwards.

Item 2.   Management's Discussion and Analysis of Financial Condition and
          Results of Operations


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

This Quarterly Report on Form 10-Q contains certain statements that are not
historical facts, including, most importantly, information concerning possible
or assumed future results of operations of Ridgefield Acquisition Corp. (the
"Company") and statements preceded by, followed by or that include the words
"may," "believes," "expects," "anticipates," or the negation thereof, or similar
expressions, which constitute "forward-looking statements" within the meaning of
the Section 27A of the Securities Act of 1933 and Section 21E (the "Reform Act")
of the Securities Exchange Act of 1934 (the "Exchange Act"). For those
statements, the Company claims the protection of the safe harbor for
forward-looking statements contained in the Reform Act. These forward-looking
statements are based on the Company's current expectations and are susceptible
to a number of risks, uncertainties and other factors, including the risks
specifically enumerated in Company's Annual Report on Form 10-K for the year
ended December 31, 2009, and the Company's actual results, performance and
achievements may differ materially from any future results, performance or
achievements expressed or implied by such forward-looking statements. The
Company will not undertake and specifically declines any obligation to publicly
release the result of any revisions, which may be made to any forward-looking
statements to reflect events or circumstances after the date of such statements
or to reflect the occurrence of anticipated or unanticipated events. In
addition, it is the Company's policy generally not to make any specific
projections as to future earnings, and the Company does not endorse any
projections regarding future performance that may be made by third parties.

     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-K for the year ended December 31, 2009.


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

     The Company's plan of operation is 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 for a merger, acquisition, business combination or other arrangement, and
there can be no assurance that the Company will ever successfully arrange for a
merger, acquisition, business combination or other arrangement by and between
the Company and a viable operating entity.


                                       10
<PAGE>

     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,
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.


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 had been 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 presently does not hold any securities of any
publicly traded company.

     At September 30, 2010 the Company did not hold any investment securities.

     While the Company endeavors to invest in securities that have a potential
for gain, there can be no assurances that the Company will not suffer losses
based on its Investment Strategy.

                                       11

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

     For the three months ended September 30, 2010, the Company has not earned
any revenues, except for interest income of $1,588. For the same period, the
Company incurredgeneral and administrative expenses of $4,101 resulting in a net
loss from operations equal to $2,513. General and administrative expenses for
the three months ended September 30, 2010 consisted of costs associated with
maintaining the Company's status as a public company including (without
limitation) filing reports with the Securities and Exchange Commission.

     For the nine months ended September 30, 2010, the Company had revenues from
interest income of $2,405 and realized gains of $272,134 from the sale of shares
of IAAC and Argan stocks. For the same period, the Company incurred general and
Administrative expenses of $25,375 resulting in a net gain from operations of
$249,164. General and administrative expenses for the nine months ended
September 30, 2010 include costs associated with maintaining the Company's
status as a public company including (without limitation) filing reports with
the Securities and Exchange Commission and our agreement with Catalyst
Financial.


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

     During the three months ended September 30, 2010, the Company satisfied its
working capital needs from cash on hand, cash generated from interest income and
sales of investments. As of September 30, 2010, the Company had cash and cash
equivalents on hand in the amount of $893,140.

     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. 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.

Item 4T. Controls and Procedures

     We maintain "disclosure controls and procedures," as defined in Rules
13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to ensure that
information required to be disclosed by us in reports we file or submit under
the Exchange Act is recorded, processed, summarized and reported within the time
periods specified in the SEC's rules and forms, and that such information is
accumulated and communicated to our principal executive officer to allow timely
decisions regarding required disclosure.

     Evaluation of disclosure and controls and procedures.

     As of September 30, 2010, the Company carried out an evaluation, under the
supervision and with the participation of our Principal Executive Officer, of
the effectiveness of the design and operation of the Company's disclosure
controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the
Exchange Act). Based on the evaluation, the Company's Principal Executive
Officer has concluded that the Company's disclosure controls and procedures are
designed to provide reasonable assurance that information required to be
disclosed by the Company in the reports that it files or submits under the
Exchange Act is recorded, processed, summarized and reported within the time
periods specified in the SEC's rules and forms and are operating in an effective
manner.

     Changes in internal controls over financial reporting.

     There have been no changes in Company's internal control over financial
reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act)
that occurred during Company's most recent quarter that has materially affected,
or is reasonably likely to materially affect, Company's internal control over
financial reporting.

     It should be noted that any system of controls, however well designed and
operated, can provide only reasonable, and not absolute, assurance that the
objectives of the system are met. In addition, the design of any control system
is based in part upon certain assumptions about the likelihood of future events.
Because of these and other inherent limitations of control systems, there is
only reasonable assurance that the Company's controls will succeed in achieving
their stated goals under all potential future conditions.
