respects with U.S. GAAP, except for those items disclosed in note 17 to the
notes to the Consolidated Financial Statements.

Currency and Exchange Rates

The financial statements of the Company are all expressed in United States
dollars. All other financial data appearing in this Form 20-F are expressed in
United States dollars ("US $"), with the exception of certain limited cases when
reference is made to instruments denominated in Canadian dollars ("CDN $").

Transactions that were conducted in Canadian dollars or other foreign currencies
have been converted into United States dollars at the rate of exchange
prevailing at the date of such transactions, and assets and liabilities
denominated in Canadian dollars or other foreign currencies but expressed in
this Form 20-F in United States dollars have been converted into United States
dollars at the rate of exchange prevailing on the date of the applicable
financial statement.

The following table sets forth, for the periods indicated, the high, low, end of

Not

C.        Reasons for the Offer and Use of

Not
Applicable.

D.        Risk Factors

The Company and the Company's investors face a number of significant risks,
which are described below.



Going Concern

There
is substantial doubt about the Company's ability to continue as a going concern
because of the substantial losses incurred in the development state. In addition
the Company is still in the development state and it will be necessary to raise
additional funds for the continuing development, testing and commercial
exploitation of its technologies. The sources of these funds have not yet been
identified and there can be no certainty that sources will be available in the
future. As such, the realization of the Company's assets and discharge of its
liabilities is subject to significant uncertainty.



The Company's ability to continue as a going concern is dependent upon
completing the development of its technology for a particular application,
achieving profitable operations, obtaining additional financing and successfully
bringing its technologies to the market. The outcome of these matters cannot be
predicted at this time. The consolidated financial statements have been prepared
on a going concern basis and do not include any adjustments to the amounts and
classifications of the assets and liabilities that might be necessary should the
Company be unable to continue in business.



The Company Currently Has No Operating Revenue



The Company has no revenues and it does not expect to generate revenues in the
near future. If the Company fails to enter into any license agreements it will
have no revenues and even if it enters into such agreements the amount of the
revenues it receives will depend on the terms it is able to get from each
licensee and the ability of each licensee to compete in its particular market.



The Company's Technology is under Development



The
Company's technology is currently under development and is therefore not yet
proven to be commercially viable. In order that the Company may be able to
procure revenue generating licensing arrangements, significant development work
remains to be completed.



Products Using the Technology Have Not Yet Been Manufactured



The
Company's success depends on whether its technology can be manufactured in large
quantities at competitive prices. Failure to be able to manufacture large
quantities at competitive prices will seriously hurt the Company's ability to
generate revenues.



Competitors are seeking to develop Other Magnetic based Memory Technologies

Most of the major producers of memory components and devices are reported to be
conducting research directed towards the development of other non-volatile
random access memory technologies. While information concerning such research is
difficult to obtain, reports indicate that very large sums of money are being
spent and that major companies such as IBM, Motorola and Honeywell, that have
enormous resources at their disposal, are involved.



Failure To Receive Continued Financing Will Cause the Business to Suffer

Since the Company expects no revenues in the near future, the Company will need
additional financing to continue the research and development and to
successfully market the technology to potential licensees. While the Company has
had sufficient funds thus far to meet its requirements, there is no assurance it
will be able to continue to do so, and failure to raise sufficient funds in the
future will affect its ability to develop and market the technology.





Because Much of the Company's Success and Value
      Depends On Its Ownership and Use of Intellectual Property the Company's
      Failure to Protect That Property Could Adversely Affect Its Future Growth
      and Success






The
Company's success will depend on its ability to protect its intellectual
property. The Company relies primarily on patent, copyright, trademark and trade
secret laws, as well as nondisclosure agreements and other methods to protect
its proprietary technologies and processes. Despite its efforts to protect its
proprietary technologies and processes, unauthorized parties may attempt to copy
or otherwise obtain and use its products or technology without authorization,
develop similar technology independently or design around its patents. Policing
unauthorized use of the Company's products is expensive and difficult, and the
Company cannot be certain that the steps it has taken will prevent
misappropriation or infringement of its intellectual property.

Intellectual Property
      Claims Against the Company, No Matter How Groundless, Could Cause Its
      Business To Suffer












There is no assurance that any of the pending applications will be issued as
patents or that any issued patent will not be determined to be invalid at a
later date.



No Foreseeable Dividends



Micromem has never paid a dividend on its securities. Micromem does not
anticipate paying dividends in the foreseeable future.



Issuance of Additional Securities and Dilution



The board of directors of Micromem has the authority to issue additional Common
Shares or other securities of Micromem without the prior consent or vote of
Micromem's shareholders. The issuance of additional Common Shares may have the
effect of diluting the proportionate equity interest and voting power of holders
of Shares.



Dependence on Key Personnel



The Company's success will depend on its ability to retain certain of its senior
management and key technical personnel. It will also depend, to a large extent,
on its ability to attract and retain additional highly skilled personnel in the
future.

The Company may be materially affected by global economic and political
conditions

The
Company's ability to generate revenue may be adversely affected by the slowdown
in the global economy as companies delayed their purchase decisions, reduced
their technology spending budgets, increased their purchase authorization
approval requirements, and reduced their capital expenditures by maximizing the
current capacities of their data storage equipment. The Company does not
currently anticipate any significant improvement in technology spending during
2003. During 2002, the Company implemented various cost-saving measures to help
mitigate the adverse effects of the slowdown in the global economy. The Company
cannot provide any assurance that a prolonged economic downturn will not have
additional adverse effects on the Company's financial condition, results of
operations, or our ability to generate revenue growth. Furthermore, the Company
cannot provide any assurance that our cost-saving measures will be successful or
sufficient to allow the Company to continue to generate improved operating
results in future periods.

The Company's financial condition and results of operations could also be
materially affected by unstable global political conditions. Terrorist attacks
or acts of war could significantly disrupt the Company's operations and the
operations of the Company's future customers, suppliers, distributors, or
resellers. The Company cannot predict the potential impact on its financial
condition or results of operations should such events occur.

The
Company may be materially affected by aggressive competition

The memory and data storage industry is highly competitive, and customers make
their decisions based on a number of competitive factors, including the
following:

• Functionality 
    •Technology 
    •Performance 
    • Reliability 
    •System scalability 
    •Price 
    • Quality 
    • Product availability 
    • Customer service 
    •Brand recognition

The Company must address each of these factors effectively in order to
successfully compete. If the Company is unable to adapt its products and
services to changes in these competitive factors, it may never gain market
share.

The
Company may be materially affected by rapid technological change and evolving
industry standards

Short product life cycles are inherent in high-technology industries due to
rapid technological change and evolving industry standards. The Company's future
financial condition and results of operations depend on its ability to respond
effectively to these changes. The Company cannot provide any assurance that it
will be able to successfully develop, manufacture, and market innovative new
products or adapt its current products to new technologies or new industry
standards. In addition, customers may be reluctant to adopt new technologies and
standards, or they may prefer competing technologies and standards. Because the
technology market changes so rapidly it is difficult to predict the rate
adoption of its ferromagnetic memory technology.

The Company may be materially affected by risks associated with new product
development

New product research and development is complex and requires the investigation
and evaluation of multiple alternatives, as well as planning the design and
manufacture of those alternatives selected for further development. Research and
development efforts could be adversely affected by any of the following:

• Hardware and software design flaws 
    • Product development delays 
    • Changes in data storage technology 
    • Changes in operating systems 
    • Changes in industry standards

Manufacturing new products involves integrating complex designs and processes,
coordinating with suppliers for parts and components, and managing manufacturing
capacities to accommodate forecasted demand. Failure to obtain sufficient
quantities of parts and components, as well as other manufacturing delays or
constraints, could adversely affect the timing of new product introductions. The
Company has experienced product development delays in the past that adversely
affected its financial position.

The
Company may be materially affected by the risks associated with developing and
protecting intellectual property

The Company depends on its ability to develop new intellectual property that
does not infringe on the rights of others. The Company cannot provide any
assurance that it will be able to continue to develop such new intellectual
property.

The Company relies on a combination of U.S. patent, copyright, trademark, and
trade secret laws to protect its intellectual property rights. The Company
enters into confidentiality agreements relating to its intellectual property
with its employees and consultants.

Due to financial constraints, the Company has determined not to file patent and
trademark registration applications with foreign governments; this may expose us
and our technologies to infringement in foreign jurisdictions.

Despite all of the Company's efforts to protect its intellectual property
rights, unauthorized parties may attempt to copy or otherwise obtain or use its
intellectual property. Monitoring the unauthorized use of the Company's
intellectual property is difficult, particularly in foreign countries. The
Company cannot provide any assurance that it will be able to adequately protect
its intellectual property.

The
Company may be materially affected if it is unable to attract, retain, and
motivate key employees

The Company's future success depends in large part on its ability to attract,
retain, and motivate its key employees. The Company faces significant
competition for individuals who possess the skills required to design, develop,
manufacture, and market the Company's technologies. An inability to successfully
attract, retain, and motivate these employees in the future could have an
adverse effect on the Company's future financial condition and results of
operations.

Volatility of Common Share Price and Volume

Shareholders of Micromem may be unable to sell significant numbers of common
shares of Micromem on the NASD OTC-BB (where the common shares are currently
traded) without a significant reduction in the price of the shares, if at all.

Furthermore, there can be no assurance that the Company will be able to meet the
listing requirements of, or achieve listing on, any other stock exchange. The
market price of the common shares of the Company may be affected significantly
by factors such as fluctuations in the Company's operating results,
announcements of technological innovations or new products by the Company or its
competitors, action by governmental agencies against the Company or the industry
in general, developments with respect to patents or proprietary rights, public
concern as to the safety of products developed by the Company or others, the
interest of investors, traders and others in public companies such as the
Company and general market conditions. In recent years, the securities markets
in the United States and Canada have experienced a high level of price and
volume volatility, and the market price of securities of many companies,
particularly small capitalization companies, have experienced fluctuations which
have not necessarily been related to the operating performances, underlying
asset values or prospects of such companies.

ITEM 4.         INFORMATION ON THE
COMPANY

A.         History and Development of
the Company

Micromem is a corporation formed under the laws of the Province of Ontario,
Canada, with principal executive offices at 777 Bay Street, Suite 1910, Toronto,
Ontario M5G 2E4. Formerly known as AvantiCorp International Inc., Micromem
changed its name to Micromem Technologies Inc. on January 14, 1999. Micromem was
incorporated under the laws of the Province of Ontario, Canada, on October 21,
1985 as Mine Lake Minerals Inc. It subsequently changed its name to Avanti
Capital Corp. on June 23, 1988 and to AvantiCorp International Inc. on April 30,
1992 before becoming Micromem Technologies Inc. on January 14, 1999 in
connection with its acquisition of Pageant International.

Purchase of Pageant Technologies Incorporated

On January 11, 1999, Micromem completed the acquisition of 100% of the
capital stock of Pageant International, in exchange for 32,000,000 Common Shares
and warrants for the purchase of an additional 1,000,000 Common Shares (the
"Warrants"), representing 88.94% of the outstanding Common Shares of Micromem
(89.24% assuming exercise of all the Warrants). The acquisition was completed
pursuant to an agreement, dated December 7, 1998, among Micromem, as the
purchaser, and Ataraxia Corp., as the vendor, and Pageant International. The
Warrants were exercisable at CDN $2.00 per share through January 11, 2000 and
thereafter at CDN $2.30 per share through January 12, 2001 on which date the
Warrants remaining unexercised expired. The total purchase price for the Pageant
International Common Stock was $30,000,000. The value of the Common Shares used
to pay the purchase price was determined through arm's length negotiations using
as a point of reference the price per Common Share of $1.16 on September 23,
1998 less an agreed upon discount.

The primary asset of Pageant International was an undivided 50% interest in
patents, issued in the United States and Europe, with a corresponding
application in Japan, for nonvolatile random access memory technology which was,
at the time, called MAGRAM and which is, today, called VEMRAMTM1 (the
"VEMRAMTM Patents"). The VEMRAMTM technology also includes certain improvements to
the VEMRAMTM Patents, many of which are the subject of pending patent
applications. The undivided 50% interest in the VEMRAMTM Patents was originally
conveyed to Ataraxia Corp. by Estancia Limited, a company incorporated under the
laws of the Turks & Caicos Islands ("Estancia"), pursuant to a Joint
Ownership and Licensing Agreement dated September 17, 1997 (the "Joint
Ownership and Licensing Agreement") which Ataraxia Corp. assigned to Pageant
International on October 22, 1997 with the written consent of Estancia. In
addition to the undivided 50% interest in the VEMRAMTM Patents, under the Joint
Ownership and Licensing Agreement Pageant International was granted an exclusive
worldwide license to develop, manufacture and sell the VEMRAMTMtechnology. The
Joint Ownership and Licensing Agreement requires Pageant International to pay
Estancia or its nominee a royalty of 40% of the gross profits less expenses
agreed by the parties for each technology license sold. Additionally, Pageant
International would be required to pay Estancia Limited 40% of any per unit
royalty received by Pageant less properly documented reasonable expenses
directly related to the obtaining of those royalties and as agreed by the
parties in writing.

___________________________1VEMRAMTM is a trade-mark of Memtech International Inc., a Bahamas
corporation wholly-owned by Micromem, and is used under license by Micromem and
other corporations affiliated with Micromem.



The Joint Ownership and Licensing Agreement also provided that if Pageant
International, as approved assignee of Ataraxia Corp., sold the rights to the
VEMRAMTM technology to a third party not owned or controlled by it, it would have
to pay Estancia 50% of the proceeds from such transaction. This provision makes
it clear that in the event of the sale of all of the VEMRAMTM technology rights,
50% of the proceeds would go to Estancia, reflecting its 50% undivided interest
in the technology, rather than 40% reflecting its royalty rights under the
VEMRAMTM License. Estancia is controlled by John Zammit. Mr. Zammit has no direct
control relationship with Micromem, and the management of Micromem is not aware
that Mr. Zammit has any indirect control relationship with Micromem or any
control relationship, direct or indirect, with Ataraxia Corp.

See "Item 4. Information on the Company – B. Business Overview - Recent
Developments –  Agreement to Purchase Estancia Interests".



The acquisition of Pageant International was treated as a reverse takeover for
accounting purposes. A reverse takeover is deemed to have occurred when a
company uses so much of its voting stock to purchase another company that the
former stockholders of the acquired company could be said to have ended up
controlling the company doing the acquiring. In the case of the purchase of
Pageant International by Micromem, the two former shareholders of Pageant
International ended up with a greater number of voting shares than did the
pre-acquisition Micromem shareholders and therefore have been deemed to have
apparent control. The consolidated financial statements of Micromem are
presented as a continuation of the financial position and results of Pageant
International, even though Micromem remains the legal parent and Pageant
International remains the legal subsidiary. The primary consequence of the
application of this treatment to the acquisition is that the patent rights are
recorded at $100, the historical value at which they were carried on the Pageant
International balance sheet, rather than being increased to reflect a
significantly greater valuation.



Changes to Board of Directors and Management

On January 11, 1999, immediately following the acquisition, Stephen Fleming, who
had been serving as President and Chief Executive Officer of Pageant USA, was
elected to Micromem's Board to join Salvatore Fuda and Ross McGroarty, who had
served as directors since 1992 and 1988, respectively. The Board then elected
Mr. Fuda as Chairman, Mr. Fleming as President and Chief Executive Officer, and
Mr. McGroarty, who had been serving as President, as Executive Vice President
and Secretary of Micromem. Subsequently, on March 18, 1999, Robert Patterson,
who had been serving as Chairman of the Board and Vice President of Corporate
Development of Pageant USA, was elected President and Chief Executive Officer of
Micromem to replace Mr. Fleming. On November 15, 1999, Antonio Lopes was
appointed Chief Financial Officer of Micromem. On June 15, 2000, Mr. McGroarty
resigned as Executive Vice-President of Micromem.



At the annual meeting of shareholders of Micromem held on June 29, 2000, the
following individuals were elected as directors of Micromem: Andrew Brandt,

B.         Business Overview

The Company is engaged in the development of memory technologies having the
characteristic of non-volatility, which is the ability to retain information
after power has been shut off.

The Company's Technology (as defined in the next paragraph below) is based on
ferromagnetism, which consists of microscopic magnetic elements and Hall effect
sensors deposited on a substrate of silicon or glass. Each magnetic element
stores one bit of data based on its ability to alternate between states of
magnetic polarization, which states are determined by a Hall effect sensor
normal to the magnetic field. The Company's Technology represents "1"s and "0"s
by the different polarization of magnets; for example, a magnet oriented
north/south is a "1" and a magnet oriented south/north is a "0". The magnetic
field strength and direction do not decay when power is switched off; therefore,
the memory is non-volatile.



Micromem has been pursuing the development of its two unique memory technologies
(collectively, the "Company's Technology"): (i) a memory design with the
magnetic bit aligned horizontally to the substrate (known as "HEMRAMTM 2");
and (ii) a memory design with the magnetic bit aligned vertically to the
substrate ("VEMRAMTM "). During the 2002 fiscal year, Micromem's Chief Operating
Officer oversaw an R&D team focused on the further development of the thin film
horizontal element magnetic devices and applications of this technology. The
inventor under the patent for the VEMRAMTM technology has been contracted to
assist Pageant USA in the development of the vertical element magnetic
technology. The Company has a portfolio of patents and patent applications
protecting the technologies that it is developing.

Industry Background



The
semiconductor memory industry is principally driven by the requirements of the
computing industry. The nature of the memory manufacturing industry is that it
is capital intensive, cyclical, rapidly changing and depends significantly on
patent protection.

The semiconductor industry is intensely competitive. Both low-density and
high-density nonvolatile memory products are manufactured and marketed by major
corporations possessing worldwide wafer manufacturing and integrated circuit
production facilities and by specialized product companies.



Company's Technology



The various characteristics of the Company's Technology can be better understood
by describing the three basic types of memory used by present day computers,
Random Access Memory (RAM), Read Only Memory (ROM), and secondary storage
devices such as floppy and hard disks. The three types of memory are described
below:



Random Access Memory (RAM) is memory that can be both read and
written randomly, which means that its storage locations can be accessed in any
order. Thus a computer using RAM can find and go directly to the selected
location rather than performing a sequential search. Semiconductor RAM is
usually the primary memory associated with the computer's central processing
unit (CPU), the computational unit of the computer responsible for
interpreting and executing instructions. However, RAM is volatile which
means that all stored information vanishes once the power supply is removed and
must be restored from a secondary storage device each time the power is resumed.



Two typical examples of RAM are Dynamic Random Access Memory and Static Random
Access Memory. Dynamic Random Access Memory (DRAM) uses integrated
circuits containing capacitors to achieve significant storage capacity and
speed. DRAM can be written and read in the speed range of less than 100
nanoseconds. DRAM has a major drawback in that its capacitors lose their charge
over time and therefore information contained in DRAM must be continually
refreshed. Basically, this means that on average DRAM must stop operations every
16-30 milliseconds and restore all of the data it contains or the data will
disappear. During this refresh time, the processor has no access to the
information being refreshed. Static Random Access Memory (SRAM) differs
from DRAM in that it stores information in a logic circuit referred to as a
flip-flop, rather than in a capacitor. SRAM memory does not need to be refreshed
while the power is on, but also loses its information once the power is turned
off.



Read Only Memory (ROM), like RAM, can be read randomly, but
cannot be written randomly. Unlike RAM, however, it is non-volatile and
therefore does not lose its information when a computer's power is cut off. ROM
is typically employed to store vital program information required during the
first moments after a computer is powered on. It may be used for such purposes
as forcing system test routines, directing the processor to input/output devices
or for controlling access to certain computer subsystems such as hard drives. EPROMs (erasable programmable read-only memory) and EEPROMs
(electrically erasable read-only memory) are read only memories that can be
erased and rewritten, but must be written "en masse," rather than at the
individual word level. "Flash" memory is a form of EEPROM that is widely used
today in such devices as cell phones, modems and personal digital assistants.
The drawbacks to Flash memory are that write times are slower, the number of
read/write cycles are limited and the requirement for significantly higher power
than DRAM to store data.

Secondary Storage Devices include Floppy Disks, which are
light and portable and are written and read by a motor driven mechanical drive.
They normally have a storage capacity in the low megabyte range. Hard Disks
far exceed floppy disks in storage capacity and have become the standard for
mass storage of data to be written and read by the processor. Both Floppy Disks
and Hard Disks are non-volatile and can be both written and read. However, since
they are serial (as opposed to parallel) devices, they are considerably slower
than RAM.



Micromem's horizontal element magnetic memory technology, HEMRAMTM , involves
producing hybrid memories based on in-plane magnetization mechanism of
horizontally oriented micron scale ferromagnetic thin films that act as storage
elements. An in-plane magnetization generates a spatially inhomogeneous field
profile with a narrow fringe field normal to the substrate. This fringe field
results in a measurable Hall voltage across the probe terminals when a current
flows through the sensor. Changing current direction will lead to a reversed
Hall voltage. This intrinsically bipolar output forms the basis of nonvolatile
storage, logic gate and field sensing.



Micromem's vertical element magnetic memory technology, VEMRAMTM, uses a novel
hybrid Hall effect MRAM scheme which utilizes out-of-plane magnetization induced
by vertically oriented high-aspect-ratio ferromagnetic posts. The VEMRAMTM cell
comprises two parts: a high-aspect-ratio ferromagnetic storage post or "bit"
(memory element) and a patterned high-mobility thin film Hall sensing element (InAs
or InSb) underneath the bit. The bit is vertically positioned or normal to the
probe surface, which is necessary to suppress so-called "N" rotation, a tendency
for the magnetic field in a ferromagnet to rotate away from its set direction
under the influence of an external perturbing magnetic field. The memory bits
and driving circuits can be directly constructed on a wafer where Hall sensors
have already been produced by direct implantation or by epitaxial growth and
patterned etching. In the writing operation, each bit is coerced to change its
magnetic states by the drive current flowing along the surrounding single-turn
electrical loop. When the drive current is reversed, the remnant state switches
from one state to the other to store a new binary number. The reading process
remains essentially the same as in the in-plane magnetization arrangement.



Competition

The Company is aware of others conducting research and development in
the magnetic non-volatile memory area. These include IBM Research (San Jose,
California), Ovonyx, Inc. (Troy, Michigan), Hewlett-Packard (Palo Alto,
California), Honeywell (Plymouth, Minnesota) and Motorola (Phoenix, Arizona).



In February 2002, Cypress Semiconductor Corp. formed a subsidiary to develop
magnetic RAM in association with NVE and has allocated $22 million in research
and development to bring a product to market.



The basic MRAM cell consists of one transistor and one magnetic tunneling
junction. Reading the cell involves passing a current through the magnetic
tunneling junction (MTJ) stack. Two main centers of MRAM research are at IBM and
Infineon. IBM and Infineon have alternative MRAM technologies based on the giant
magneto resistance (GMR) principle. GMR memory elements consist of two
ferromagnetic layers separated by a conductive nonmagnetic interlayer. The
electrical resistance is high in the absence of external magnetic field;
however, an applied external field forces the initially anti-parallel
magnetization in the coupled films into parallel alignment and the resistance
drops. The high or low resistance determines the data storage state. MTJ cells
have similar sandwiched structures but the interlayer is insulating instead of
conducting. In contrast to GMR structures in which the sense current usually
flows parallel to the layers, the current in MTJ flows perpendicularly to the
layers of the stack.



Neither
the current stages of development of these companies' non-volatile technologies
nor their projected development completion dates are known.



Micromem's technology is based on a variety of realizations of low-cost hybrid
Hall effect magnetic cells. Unlike GMR and MTJ, hybrid Hall effect magnetic
memory cells combine a ferromagnetic storage element and an integrated Hall
effect device to read information by sensing magnetization polarities. For
example, a high-mobility thin film Hall sensor (also called a Hall cross due to
four perpendicularly oriented leads connected to the sensor) can be used as an
excellent local magnetometer for measuring the strength of field generated by
ferromagnetic films or structures due to its high sensitivity and tolerance of
broad range of temperatures. This concept utilizes the well-known Hall effect.
When a current flows through a semiconductor in the presence of a transverse
magnetic field, the mobile charges drift in a direction perpendicular to both
the electric and magnetic fields because of the Lorentz force. This gives rise
to a transverse voltage difference called Hall voltage. The reversed magnetic
field also alters the polarity of the voltage, making the Hall probe a suitable
tool for recording binary information.



The Company will face intense competition when its technologies are developed to
a point at which they may be sold and/or licensed. The Company will be required
to introduce its technologies into a well developed market and compete with
major corporations who manufacture, sell and license existing memory products
such as DRAM, SRAM, EPROM, EEPROM and Flash memory. The market for memory
technologies is dominated by major corporations who have established market
segments for their memory technologies and products, and have significantly
greater financial and other resources which are required to design, develop,
manufacture, market, sell and license their products and technologies. Many of
these major corporations have worldwide wafer manufacturing and integrated
circuit production facilities.



The success of the Company's Technology will be determined by the following
factors for which it has not yet been tested or measured: (i) the ability to
build fully functional sub-micron scale devices for specific applications; (ii)
the ability of manufacturers to incorporate the technology into existing
manufacturing capabilities without significant retooling and material costs;
(iii) price competitiveness; and (iv) availability and costs of raw materials.



After completion of the development of the company's Technology, the ability of
the Company to compete successfully will depend on elements outside of its
control, including the rate at which customers incorporate the Company's
Technology into their products, the success of such customers in selling those
products, the Company's protection of its intellectual property, the number,
nature and success of competitors and their product introductions, and general
market and economic conditions. In addition, the Company's success will depend
on its ability to develop, introduce, and license or sell in a timely manner its
technology or products incorporating its technology and to compete effectively
on the basis of factors such as speed, density, die size and packaging.



Recent Developments



In June 2002, the Company's management determined that its research and
development operations required restructuring due to financial constraints, in
order to continue the development of its magnetic non-volatile memory
technology. Accordingly, the Company commenced restructuring its operations in
July 2002 to achieve an orderly transition of its R&D program. As part of this
restructuring, Pageant USA closed its Lee's Summit, MO facility by August 31,
2002 and Micromem downsized its head office in Toronto by end of the fiscal
year, October 31, 2002. Micromem and Pageant USA terminated Dr. Dale Hensley as
Chief Operating Officer effective as of September 24, 2002. Pageant USA
terminated all of its other employees by October 31, 2002. Dr. Hensley resigned
as a director of Micromem on October 9, 2002 and as a director of Pageant USA on
September 26, 2002. In September 2002, Pageant USA terminated its agreement with
Townsend Capital Inc. pursuant to which Pageant USA occupied the offices,
laboratory and clean room it had occupied at Summit Technology Campus, Lee's
Summit, Missouri.



Infrastructure Agreements with University of Toronto



On November 1, 2002 ("effective date"), Micromem entered into an Infrastructure
Agreement with the University of Toronto, to fund the assembly of a facility for
research and development and fabrication of Magnetic Memory ("MMF").



Under the terms of the agreement, Micromem has committed to contribute $231,140
(CDN$360,000) in cash to fund the direct costs of MMF. The sum is payable to
University of Toronto as follows:

i.            $120,000 on
execution of agreement, which was paid on November 28, 2002;
            ii.          
$120,000 at end of the two months following the effective date; and
            iii.         
$120,000 at end of the four months following the effective date.

University of Toronto and MMO



On October 24, 2002, Micromem entered into a 2-year research collaboration
agreement ("U of T Research Collaboration Agreement") with Materials and
Manufacturing Ontario ("MMO"), the University of Toronto, and Dr. Harry Ruda,
Chair Professor in Nanotechnology. Through the collaboration, Micromem will
continue its involvement in the research and development of magnetic memory
technology, which will be carried out by a highly skilled research team headed
and assembled by Dr. Ruda. Under the agreement, Micromem and MMO will each
provide (CDN) $272,000 of funding and the combined (CDN) $544,000 will be used
to cover the operating expenses of the research collaboration over a term of two
years. Under the agreement, Micromem will maintain its ownership of its
portfolio of patents and intellectual property to date.

Micromem will have the first right to an exclusive and perpetual worldwide
sub-license for all uses of the technology developed under the collaboration
(except that the University may use the technology for educational and research
purposes). MMO will be entitled to receive a royalty on Micromem's manufacturing
revenues from the sale of products incorporating the technology developed under
the collaboration. A separate royalty will be negotiated in the future on
revenues to be generated by Micromem from sub-licenses of the technology
developed under the collaboration.



The research collaboration agreement contemplates a number of milestones under a
comprehensive research plan. The research will be carried out from research
facilities at the University of Toronto.

MMO is one of four Ontario Centres of Excellence (OCE) established by the
provincial government to promote commercial research partnerships between
universities and industry. The OCE program is funded by the Ministry of
Enterprise, Opportunity and Innovation; and is part of the provincial
government's $2 billion investment in Ontario's knowledge economy making Ontario
more competitive through innovation in science and technology

FabTech Inc.



On
May 1, 2001, Pageant Technologies (USA) Inc., a wholly owned subsidiary of
Micromem, entered into a support services agreement ("Fabtech Agreement") with
Fabtech Inc. located in Lee's Summit, Missouri. Under the agreement, as amended
from time to time, during the 2002 fiscal year, FabTech provided access to its
equipment and facilities and assigned engineering and other technical staff to
work directly with Micromem's research and development team at FabTech's
facilities. The objective of the relationship was to facilitate the fabrication
of samples using Micromem's HEMRAMTM memory design. Pageant USA terminated the
Fabtech Agreement effective as of August 31, 2002.

Honeywell FM&T

On December 9, 1999, Pageant USA, a subsidiary of Micromem, entered into an
Agreement (the "DOE Agreement") with AlliedSignal Federal Manufacturing &
Technologies ("AlliedSignal") operating under contract with the US Department of
Energy ("DOE") to conduct an engineering evaluation of the Company's technology.
AlliedSignal was subsequently acquired by Honeywell, Inc., which assumed
responsibility for both performance of the DOE Agreement and management of the
DOE Facility through Honeywell Federal Manufacturing & Technologies ("Honeywell
FM&T"). The DOE Agreement was subsequently amended on July 10, 2000 to expand
the scope of work to be completed by Honeywell FM&T. Pursuant to the amended DOE
Agreement, Honeywell FM&T agreed that, in addition to providing an evaluation of
the technology, it would provide engineering and manufacturing services to
Pageant. The DOE Agreement terminated in August 2002.



Agreement to Purchase Estancia Interests

On December 10, 2000, Micromem and Pageant International entered into an
agreement (the "Purchase Agreement") with Estancia Limited and Richard M. Lienau
("Lienau") to purchase from Estancia and Lienau all interests (the "Estancia
Interests") in the VEMRAMTM Patents and the VEMRAMTM technology and all other
rights, interests and entitlements held by Estancia and Lienau as set forth in
the Joint Ownership and Licensing Agreement. The Purchase Agreement is subject
to all required approvals from securities regulatory authorities.



Under the Purchase Agreement which closed on March 9, 2001, Pageant
International agreed to pay a purchase price of $50.0 million (the "Purchase
Price") to Estancia, as follows:

|i.   |  | $10.0 million was paid on closing
    (after receipt of regulatory approvals), in the form of 2,007,831 common
    shares of Micromem (or $8.0 million worth of Micromem's common shares ("Micromem
    Shares") based on the close price on the closing date, being $3.98 per
    share) and $2.0 million in cash;                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
|---- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|ii.  |  | $20.0 million, will be paid
    if and when either: (a) certification is received from Honeywell Federal
    Manufacturing & Technologies that fully integrated, randomly addressable
    memory matrices of VEMRAMTM technology have met certain stipulated
    performance standards, or (b) Micromem or any of its affiliates executes a
    definitive agreement for the sale or licensing of the VEMRAMTM technology to
    an arm's length third party for any commercial purposes other than testing
    or evaluation of the technology; payable in the form of cash and Micromem
    Shares to be determined by Pageant International provided that a minimum of
    50% of the $20.0 million shall be paid in Micromem Shares valued at the
    close of trading on the date of such certification receipt, sale or
    licensing; and
|iii. |  | $20.0 million, will be paid
    if and when Micromem or any of its affiliates executes a definitive
    agreement for the sale or licensing of any technology (including the VEMRAMTM
    Technology) owned by Micromem to an arm's length third party for any
    commercial purposes other than testing or evaluation of the technology;
    payable in the form of cash and Micromem Shares to be determined by Pageant
    International provided that a minimum of 50% of the $20.0 million shall be
    paid in Micromem Shares valued at the close of trading on the date of
    execution of the license.                                                                                                                                                                                                                              

Notwithstanding the provisions triggering the two $20.0 million payments (the
"Trigger Events"), Pageant International has the right to pay any portion or all
of the Purchase Price at any time following the Closing Date through a
combination of cash and a number of common shares of Micromem, provided that a
minimum of 50% of such payment shall be through the issuance of common shares of
Micromem. In the event that one or both of the Trigger Events do not occur prior
to three years following the Closing Date, Pageant International shall be deemed
to have caused a proportionate interest in the Estancia Interests to be conveyed
to Estancia where the proportionate interest is calculated as the ratio of the
portion of the Purchase Price remaining unpaid at such date over $50.0 million.
In the event that Pageant International or Micromem default in the payment of
any portion or all of the Purchase Price when due, Pageant International shall
be deemed to have caused a proportionate interest in the Estancia Interests to
be conveyed to Estancia where the proportionate interest is calculated as the
ratio of the portion of the Purchase Price remaining due and unpaid at such date
over $50.0 million.



At the closing of the Purchase Agreement, on March 9, 2001, Estancia was
required to and it did enter into a three year technology development agreement
with Pageant International for the provision of the services of Richard Lienau
in respect of the continued development of VEMRAMTM technology (the "Technology
DevelopmentAgreement"). The Technology Development Agreement provides
for fees to Estancia of $215,000 per annum and a budget for the continued
development of VEMRAMTM of up to $500,000 per annum. Effective April 23, 2002,
the Technology Development Agreement was amended to extend the term of the
agreement for an additional eight months commencing March 9, 2004 through to
November 9, 2004, and to provide a reduction of the monthly fees payable to
Estancia to $107,500 during the periods from June 1 to December 2002, and during
the extended period.



The acquisition of the Estancia Interests under the Purchase Agreement could
result in additional payments of cash by Pageant International and additional
issuances of Common Shares by Micromem. The amount of cash, if any, to be paid
to Estancia and the number of Common Shares, if any, to be issued will depend
upon several factors including whether or not the Trigger Events occur prior to
three years following the Closing Date and the market price of Micromem's Common
Shares on the date of each Trigger Event. The table below sets forth the amount
of cash and the number of Common Shares of Micromem that will be required to be
paid and issued if both Trigger Events occur, prior to three years following the
Closing Date, based on assumed market prices of Micromem's Common Shares of
$4.00, $6.00 and $8.00 on both dates on which the Trigger Events occur. The data
presented in the table is also based upon the assumption that 25% of the portion
of the purchase price due upon each Trigger Event will be paid in cash and the
balance of 75% will be paid through the issuance of Common Shares. The actual
amounts of cash to be paid and the number of Common Shares to be issued may vary
significantly from the amounts and numbers set forth in the table below if one
or more of the Trigger Events does not occur prior to three years following the
Closing Date, if the market prices of Micromem's Common Shares on the dates of
the Trigger Events are different than those assumed in the table below or if the
percentage of the Purchase Price payable upon a Trigger Event which is paid in
the form of cash or shares varies from 25% and 75% respectively.

Fiscal 2002 Compared to Fiscal 2001

The
Company had no operating revenue, its only activities being the development of
its memory technologies. Its only income during 2002 was $165,892 (2001:
$196,520) being principally the interest it earned on excess funds deployed in
short-term deposits and revenue generated through an engineering services
contract.



Costs and expenses have increased from $4,725,931 in 2001 to $12,934,444 in
2002. The increase includes a $10,000,000 write down of royalty rights, which,
when excluded from costs and expenses would result in a decrease of 37.9% of
costs and expenses when compared to similar costs and expenses in 2001.



In March 2001, Micromem's wholly-owned subsidiary, Pageant International,
purchased a 40% gross profits royalty ("Estancia Royalty") related to patents
and patent applications for VEMRAMTM technology ("VEMRAM Patents") and the
remaining 50% interest in the VEMRAMTM Patents and all rights, entitlements and
interests held by Estancia Limited and Richard Lienau under the Joint Ownership
and Licensing Agreement dated as of September 17, 1997 pursuant to an asset
purchase agreement (the "Asset Purchase Agreement") among Micromem, Pageant
International and Estancia Limited and Richard Lienau for a purchase price of
$10 million (which was paid at closing) and a further maximum of $40 million to
be paid upon certain stipulated milestones being met. During the year, the
Company decided to restructure its operations by closing its research and
development facility and adopted a plan to continue its research and development
program through a research collaboration with the University of Toronto.
Micromem determined that there was significant uncertainty that any amounts
would have become payable in respect of the Estancia Royalty. Accordingly, it
was determined that a write down of the Estancia Royalty rights in the amount of
$10,000,000 was appropriate under current generally accepted accounting
principles. Notwithstanding the write down, Micromem is committed to continue
its research and development of magnetic memory technology through its research
collaboration with the University of Toronto.

During
the year, the Company expended $1,601,624 (2001: $2,212,679) related to its
efforts on research and development of its memory technologies, representing
54.6% (2001: 46.8%) of total expenditures (excluding the royalty rights write
down). During the fourth quarter of 2002, Micromem entered into a two year
research collaboration agreement whereby researchers at the University of
Toronto will undertake the research and development of magnetic memory
technology in collaboration with Micromem. Furthermore, Micromem was successful
in obtaining matching funds from Materials and Manufacturing Ontario (MMO – a
non profit organization) pursuant to a research collaboration agreement among
Micromem, the University of Toronto, Dr. Harry Ruda and MMO. Over the two-year
period, Micromem will provide CDN$272,000 (approximately $175,000) with matching
contributions from the MMO towards the research and development to be undertaken
under the research collaboration. In the fourth quarter of 2002, Micromem paid
$87,432 (CDN$136,000) against its commitment. Micromem will have the first right
to an exclusive and perpetual worldwide sub-license for all uses of the
technology developed under the collaboration. MMO will be entitled to receive a
royalty on Micromem's manufacturing revenues from the sale of products
incorporating the technology developed under the collaboration.



The Company has also continued its efforts to reduce administrative expenses in
all areas of operation. The Company's facilities in Lee's Summit have been
closed and all employees at the facility were terminated. The Company has also
undertaken to control costs performed by outside service providers by performing
the work in-house. Furthermore, Micromem has downsized its head office which
will continue to reduce costs into the future. As a result of these efforts,
general administration expenses decreased by 13.9% from $403,178 in 2001 to
$347,256 in 2002; professional fees decreased by 44.5% from $473,653 in 2001 to
$262,927 in 2002; travel and entertainment decreased by 64.3% from $205,757 in
2001 to $73,385 in 2002.



Wages and salaries decreased 59.0% from $1,372,375 in 2001 to $562,532 in 2002
as a result of decreasing employee levels (as discussed above) and as a result
of changes to the Chairman and CEO's 2001 employment agreement, with effect from
November 1, 2001. Effective February 13, 2002, Mr. Fuda resigned as President
and Chief Executive Officer of Micromem but continued as Chairman and a director
of Micromem and as a director of certain subsidiaries of Micromem. Mr. Fuda's
compensation was reduced, with effect from November 1, 2001, to $1.00 per year.



Amortization of patents and trademarks commenced in 2002 amounting to an expense
of $31,338. Patents and trademarks will be amortized over 10 years.



Amortization
of capital assets decreased from $65,298 in 2001 to $40,635 in 2002 as a result
of dispositions of assets due to downsizing.



Micromem had a net loss of $12,733,015 for 2002 or $0.27 loss per share compared
to a net loss of $4,559,625 in 2001 or $0.10 per share. The effect on loss per
share of the royalty write down in 2002 was $0.22 per share.



Fiscal 2001 Compared to Fiscal 2000



The Company had no operating revenue, its only activities being the development
of its memory technologies. Its only income during 2001 was $196,520 being
principally the interest it earned on excess funds held in short-term deposits.



Costs and expenses decreased 35.9% to $4,725,931 during 2001 from $7,374,587
during 2000.



The Company continued to focus its efforts in progressing the research and
development of its memory technologies by incurring $2,212,679 during 2001
(2000: $1,205,777) that is 84% higher than what was expended during 2000. Since
inception, the Company had expended a total of $3,923,744 as direct costs
relating to the research and development of its memory technologies by the end
of 2001. The Company had entered into a services agreement with Fabtech Inc., a
semi-conductor company, to support the further development of the Company's
technologies. In the last 4 months of 2001, the Company employed 5 additional
research engineers with varied skills and experience, to expand the development
efforts.



The share compensation costs of $754,125 (2000: $3,247,721), included in Wages
and Salaries, relate to options exercised by the Chairman that were granted
under his 2000 Employment and Option Agreement ("2000 Employment Agreement") and
the value of shares that are accrued under his new employment agreement ("2001
Agreement") that commenced on January 1, 2001 and that was approved at the
annual meeting of shareholders of the Company on March 14, 2001. The Chairman
exercised 714,686 options that were granted to him under the 2000 Employment
Agreement on January 17, 2001. The compensation cost under the 2000 Employment
Agreement for 2001 includes a credit of $677,420. An accrual of $1,431,545 has
been made for the value of shares that are accrued but not issued under the 2001
Agreement at October 31, 2001. The 2000 share compensation costs of $3,247,721
relate to compensation agreements the Company had with the Chairman and Mast
Holding (Bermuda) Ltd., a company controlled by the former President and Chief
Executive Officer of the Company.



Professional
fees decreased 57% to $473,653 in 2001 from $1,086,839 in 2000 reflecting
primarily legal and accounting fees incurred in 2000 related to the preparation
and filing of the Company's registration statement under US securities laws. The
reduction in professional fees is also attributable to the addition of a General
Counsel and a Chief Financial Officer to the management team.



Wages and salaries (excluding the share compensation costs) increased 41% to
$618,250 in 2001 from $440,578 in 2000 principally due to the hiring of
additional employees to meet the requirements of an expanding operation.



Amortization expenses increased in line with the increase in capital assets
acquired to help the progress of the research and development efforts, excluding
the one-time impairment loss of $140,000 recorded in 2000.



Micromem had a net loss of $4,559,625 for 2001 or $0.10 per share, a decrease of
38% over the net loss of $7,259,356 for 2000 or $0.19 per share.



Unaudited quarterly financial information

(all amounts in United States dollars)

|Quarter ended,      | October 31, | July 31, | April 31, | January 31, | October 31, | July 31,  | April 31, | January 31,
|------------------- | ----------- | -------- | --------- | ----------- | ----------- | --------- | --------- | -----------
|                    |             | 2002     |           |             | 2001        |          
|Total Revenue       | 57,743      | 27,931   | 66,547    | 13,671      | 49,147      | 39,643    | 57,020    | 50,710     
|Loss for the period | 10,423,341  | 628,603  | 797,439   | 883,632     | 501,722     | 1,343,816 | 1,351,559 | 1,362,528  
|Loss per share:     | 0.22        | 0.01     | 0.02      | 0.02        | 0.01        | 0.03      | 0.03      | 0.03       
|Basic and diluted   |             |          |           |             |             |           |           |            

Notes:

1. The decrease in the loss for the quarter ended October
  31, 2001 is principally due to the reversal of $677,420 in this quarter,
  relating to the 2000 compensation agreement with the Chairman, due to the
  decline in stock price between October 31, 2000 and the vesting date of
  January 2, 2001.

2. The increase in the loss for the quarter ended October
  31, 2002 is due to a $10,000,000 write down of royalty rights, the effect of
  which is $0.22 per share.

B.          Liquidity and
Capital Resources

Liquidity

The Company currently has no cash flow from operations and will have none until
it is in a position to either license or directly produce and sell products
utilizing its memory technologies.



Micromem currently has no lines of credit in place and must obtain equity
financing from investors and from persons who hold outstanding options in order
to meet its cash flow needs until it can generate revenues.



Micromem has granted to its directors, officers and other employees a number of
options to purchase shares at prices that are at or above market price on the
date of grant. None of the optionees has any obligation to exercise his options
and there can be no assurance that Micromem will realize any funds.



Capital Resources



Micromem had no material commitments for capital expenditures as of October 31,
2002 or 2001. In March 2001, Micromem and its wholly owned subsidiary, Pageant
International, completed the Asset Purchase Agreement described above. The total
consideration payable in respect of the purchased assets under the Asset
Purchase Agreement is $50 million in the form of cash and shares. Of this
amount, $10 million was paid at closing through a cash payment of $2.0 million
and the issuance by Micromem of 2,007,831 common shares valued at $3.98 per
share. The balance of $40 million is payable in two equal amounts of $20 million
each upon achievement of certain stipulated milestones provided that a minimum
of 50% of each $20 million payment shall be in the form of shares of Micromem.
None of the stipulated milestones have been met and therefore no amounts have
been paid toward the balance of the $40 million purchase price. If no further
payments toward the purchase price are made to Estancia under the Asset Purchase
Agreement, Pageant is deemed to have conveyed back a percentage of the VEMRAMTM
Patents and to have granted a gross profits royalty to Estancia Limited such
that Pageant would remain holding a 60% interest in the VEMRAMTM Patents and it
would be required to pay a 32% gross profits royalty to Estancia Limited in
respect of the VEMRAMTM technology.



Subsequent to the year end, Micromem entered into an infrastructure agreement
with the University of Toronto to fund the assembly of a facility for research
and development and fabrication of magnetic memory, which, among other things,
will be used for research and development related to collaborations between the
University and Micromem. Micromem has committed to contribute $231,140 ($360,000
in Canadian funds) in 2003 pursuant to the agreement.



Change in accounting policy



Effective
November 1, 2001, the Company changed its accounting policy for patents and
trademarks to be recorded at cost less accumulated amortization which is
provided on a straight-line basis over ten years. In prior years, the Company
accounted for its patents and trademarks at cost and amortization was to
commence on an appropriate basis to charge off the cost over the future benefit,
not exceeding the legal life, when sales commence. There was no material impact
on prior years consolidated financial statements and accordingly, the
comparative consolidated financial statements have not been restated.



For the year ended October 31, 2002, the change in accounting policy resulted in
an increase in amortization expense and net loss by $31,338 and there was no
material impact on net loss per share.



Critical accounting policies



The preparation of the Company's consolidated financial statements is based on
the selection and application of critical accounting policies, some of which
require management to make significant estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets
and liabilities at the date of the consolidated financial statements and the
reported amounts of revenue and expenses during the reporting periods. Actual
results could differ from these estimates. The Company believes that the
following are some of the critical judgment areas in the application of its
accounting policies that currently affect the Company's financial condition and
results of operations.



The Company had royalty rights capitalized as an intangible asset on its balance
sheet. The determination of the recoverability of this amount and whether or not
this asset is impaired involves significant judgments. In assessing the
recoverability of this intangible assets, the Company considered whether the
recoverability of the asset was probable or imminent to assess the future
benefit, also considered the degree of certainty to justify carrying the
intangible asset forward. Notwithstanding the fact that management has not
abandoned the continued development of the technology and is working to pursue
the development through recent arrangements with the University of Toronto, and
management anticipated it will achieve commercialization, for accounting
purposes an impairment in the asset exists based on the significant uncertainty
that royalties would be payable to Estancia in the foreseeable future.
Accordingly, management has written down the balance of the royalty rights.

  Articles of Incorporation
  Incorporation Details and Objects of Micromem
  Micromem was incorporated under the laws of the Province of Ontario, Canada,
  on October 21, 1985 as Mine Lake Minerals Inc. It subsequently changed its
  name to Avanti Capital Corp. by filing Articles of Amendment on June 23, 1988
  and to AvantiCorp International Inc. on April 30, 1992 before becoming
  Micromem Technologies Inc. on January 14, 1999. The Articles of Incorporation
  of Micromem provide that there are no restrictions on the nature of the
  business to be carried on by Micromem.

Summary of Directors Powers and Authorities
  The
  rights, duties, powers and authorities of the Board of Directors of Micromem
  are set out in the Articles of Incorporation (the "Articles") and by-laws (the
  "By-Laws") of Micromem and the statutory provisions of the Business
  Corporations Act (Ontario) ("OBCA"). The following is a selected summary
  of the Articles, By-Laws and applicable provisions of the OBCA as they relate
  to selected rights, duties, powers and authorities of the Board of Directors
  of Micromem.
  The Articles of Micromem provide for a minimum of three and a maximum of 12
  directors. The OBCA prescribes that an offering corporation must have a
  minimum of three directors, a majority of whom are Canadian residents and at
  least one third of whom are not officers or employees of Micromem or its
  affiliates. The Board of Directors may, between annual shareholders meetings,
  appoint one or more additional directors to serve until the next annual
  shareholders meeting provided that the number of directors so added may not
  exceed by one-third (1/3) the number of directors required to have been electd
  at the last annual meeting of shareholders.
  The Chairman of the Board of Directors or any one director may call a meeting
  upon the provision of forty-eight hours notice to each director in the manner
  prescribed in the By-Laws. Any such notice shall include the items of business
  to be considered at the meeting. A majority of the directors constitute a
  quorum provided that half of those directors present are Canadian residents.
  Business cannot be transacted without a quorum. A quorum of directors may vote
  on any matter of business properly brought before the meeting provided that
  where a director is a party to a material contract or proposed material
  contract or has a material interest in the matter to be considered, such
  director must disclose his or her interest at the earliest possible date,
  request the conflict be noted in the minutes of the meeting, and with a few
  limited exceptions enumerated in the By-Laws, refrain from voting on the
  matter in which the director has a material interest. There is no limitation
  on the Board of Directors to vote on matters of their remuneration provided
  such remuneration is disclosed in the financial statements and annual
  shareholder proxy materials.
  The Board of Directors has broad borrowing powers and may, without
  authorization from the shareholders, (a) borrow money on the credit of
  Micromem; (b) issue, re-issue, sell or pledge debt obligations of Micromem;
  (c) subject to restrictions respecting financial assistance prescribed in the
  OBCA, give a guarantee on behalf ofMicromem to secure the performance
  of an obligation of any person; and (d) mortgage, hypothecate, pledge or
  otherwise create a security interest in all or any property of Micromem, owned
  or subsequently acquired, to secure any obligation of Micromem.
  
  A person is qualified to be or stand for election as a director provided such
  person is at least 18 years of age, is not a bankrupt and is not found to be
  of unsound mind by a court in Canada or elsewhere. There is no requirement for
  a director to hold shares of Micromem.

Securities of Micromem
  The authorized capital of Micromem consists of an unlimited number of common
  shares "Common Shares"), of which 46,700,937 shares were issued and
  outstanding as of October 31, 2002, and 2,000,000 special, redeemable, voting
  preference shares ("Special Shares"), none of which were outstanding, as of
  October 31, 2002.
  Holders of Common Shares will be entitled to receive notice of, attend and
  vote at all meetings of the shareholders of Micromem. Each Common Share
  carries one vote at such meetings. In the event of the voluntary or
  involuntary liquidation, dissolution or winding-up of Micromem, after payment
  of all outstanding debts, the remaining assets of Micromem available for
  distribution will be distributed to the holders of Common Shares. Dividends
  may be declared and paid on the Common Shares in such amounts and at such
  times as the directors shall determine in their discretion in accordance with
  the OBCA. There are no pre-emptive rights, conversion rights, redemption
  provisions or sinking fund provisions attaching to the Common Shares. Common
  Shares are not liable to further calls or to assessment by Micromem; provided,
  however, that pursuant to the provisions of the OBCA, Micromem has a lien on
  any Common Share registered in the name of a shareholder or the shareholder's
  legal representative for a debt owed by the shareholder to Micromem.
  Holders of Special Shares are entitled to receive notice of, attend and vote
  at all meetings of the shareholders of Micromem. Each Special Share carries
  one vote at such meetings. In the event of the voluntary or involuntary
  liquidation, dissolution or winding-up of Micromem, after payment of all
  outstanding debts, the holders of the Special Shares shall be entitled to
  receive, before any distribution of any part of the assets of Micromem among
  the holders of any other shares, the amount paid up on the Special Shares. The
  Special Shares are redeemable at the option of Micromem for the amount paid up
  on the shares. Dividends may not be declared or paid on the Special Shares and
  transfer of the Special Shares is restricted without the approval of the
  Directors of Micromem and the prior written consent of the Ontario Securities
  Commission. The number of Special Shares that may be issued and outstanding at
  any time is limited to 500,000. There are no pre-emptive rights, conversion
  rights or sinking fund provisions attaching to the Special Shares. Special
  Shares are not liable to further calls or to assessment by Micromem; provided,
  however, that pursuant to the provisions of the OBCA, Micromem has a lien on
  any Special Share registered in the name of a shareholder or the shareholder's
  legal representative for a debt owed by the shareholder to Micromem.

Rights and Privileges of Shareholders
  Only the registered holders of common shares and special preference shares on
  the record date are entitled to receive notice of and vote at annual and
  special meetings of shareholders. Where the items of business affect the
  rights of shareholders other than common shareholders, a special majority of
  two-thirds of the votes cast by the affected shareholders at the meeting
  called for such purpose is required to approve the item of business.
  Beneficial holders of common shares and special preference shares are also
  entitled to receive proxy materials in respect of meetings of shareholders in
  accordance with Canadian Securities Administrators National Instrument 54-101,
  provided that such proxies are limited in scope to instructing the registered
  shareholder (usually a brokerage house) on how to vote on behalf of the
  beneficial shareholder. There are no restrictions on the number of shares that
  may be held by non-residents other than restrictions set out in the Investment Canada Act (Canada). See "Additional Information - D. Exchange
  Controls".
  There are no provisions in the By-laws regarding public disclosure of
  individual shareholdings. Notwithstanding this, applicable Canadian securities
  legislation requires certain public disclosure of persons owning or acquiring
  common shares in excess of 10% of a corporation's issued and outstanding share
  capital.

  Micromem on the right of nonresidents of Canada or persons who are not
  Canadian citizens to hold and/or vote the Common Shares of Micromem.

E.         Taxation
  Certain Canadian Income Tax Consequences
  This
  discussion under this heading summarizes the .principal Canadian federal
  income tax consequences of acquiring, holding and disposing of common stock of
  Micromem for a shareholder of Micromem who is not a resident of Canada but is
  a resident of the United States and who will acquire and hold a share of
  common stock of Micromem as capital property for the purposes of the Income
  Tax Canada (Canada) (the "Canadian Tax Act"). This summary does not apply to a
  shareholder who carries on business in Canada through a permanent
  establishment situated in Canada or performs independent personal services in
  Canada through a fixed base in Canada if the shareholders of Micromem is
  effectively connected with such permanent establishment or fixed base. This
  summary is based on the provisions of the Canadian Tax Act and the regulations
  thereunder and on an understanding of the administrative practices of Canada
  Customs & Revenue Agency, and takes into account all specific proposals to
  amend the Canadian Tax Act or regulations made by the Minister of Finance of
  Canada s of the date hereof. It has been assumed that there will be no other
  relevant amendments of any governing law although no assurance can be given in
  this respect. This discussion is general only and is not a substitute for
  independent advice from a shareholder's own Canadian and US tax advisors.


  
  The provisions of the Canadian Tax Act are subject to income tax treaties to
  which Canada is a party, including the Canada- United States Income Tax
  Convention (1980), as amended (the "Convention").


  Dividends on Common Shares and Other Income
  
  
  Under
  the Canadian Tax Act, a non-resident of Canada is generally subject to
  Canadian withholding tax at the rate of 25 percent on dividends paid or deemed
  to have been paid to him or her by a corporation resident in Canada. Micromem
  is responsible for withholding of tax at the source. The Convention limits the
  rate to 15 percent if the shareholder is a resident of the United States and
  the dividends are beneficially owned by and paid to such shareholder, and to 5
  percent if the shareholder is also a corporation that beneficially owns at
  least 10 percent of the voting stock of the payor corporation.


  
  The amount of a stock dividend (for tax purposes) would generally be equal to
  the amount by which the paid up or stated capital of Micromem and increased by
  reason of the payment of such dividend. Micromem will furnish additional tax
  information to shareholders in the event of such a dividend. Interest paid or
  deemed to be paid on Micromem's debt securities held by non-Canadian residents
  may also be subject to Canadian withholding tax, depending upon the terms and
  provisions of such securities and any applicable tax treaty.


  
  The Convention generally exempts from Canadian income tax dividends paid to a
  religious, scientific, literary, educational or charitable organization or to
  an organization constituted and operated exclusively to administer a pension,
  retirement or employee benefit fund or plan, if the organization is a resident
  of the United States and is exempt from income tax under the laws of the
  United States.


  Dispositions of Common Shares
  
  
  Under
  the Canadian Tax Act, a non-resident of Canada is subject to Canadian tax on
  taxable capital gains, and may deduct allowable capital losses, realized on a
  disposition of "taxable Canadian property". Shares of common stock of Micromem
  will constitute taxable Canadian property of a shareholder at a particular
  time if the shareholder used the shares in carrying on business in Canada, or
  if at any time in the five years immediately preceding the disposition 25
  percent or more of the issued shares of any class or series in the capital
  stock of Micromem belonged to one or more persons in a group comprising the
  shareholder and persons with whom the shareholder and persons with whom the
  shareholder did not deal at "arm's length and in certain other circumstances.


  
  The Convention relieves United States residents from liability for Canadian
  tax on capital gains derived on a disposition of shares unless:


  the value of the shares is derived
        principally from "real property" in Canada, including the right to
        explore for or exploit natural resources and rights to amounts computed
        by reference to production, the shareholder was resident in Canada for
        120 months during any period of 20 consecutive years preceding, a and at
        anytime during the 10 years immediately preceding, the disposition and
        the shares were owned by them when they ceased to be resident in Canada,
        or the shares formed part of the business property of a "permanent
        establishment" that the holder has or had in Canada within the 12 months
        preceding the disposition.
  Certain United States Federal Income Tax
  Consequences
  The following is a general discussion of certain possible United States
  federal income tax consequences, under current law, generally applicable to a
  US Holder (as defined below) of the Company's common shares. This discussion
  does not address all potentially relevant federal income tax matters
  (including but not limited to alternative minimum tax considerations) and it
  does not address consequences peculiar to persons subject to special
  provisions of federal income tax law, such as those described below as
  excluded from the definition of a US Holder. In addition, this discussion does
  not cover any state, local or foreign tax consequences. See "Certain
  Canadian Income Tax Consequences" above.


  
  The following discussion is based upon the sections of the Internal Revenue
  Code of 1986, as amended (the "Code"), Treasury Regulations, published
  Internal Revenue Service ("IRS") rulings, published administrative positions
  of the IRS and court decisions that are currently applicable, any or all of
  which could be materially and adversely changed, possibly on a retroactive
  basis, at any time. This discussion does not consider the potential effects,
  both adverse and beneficial, of any recently proposed legislation which, if
  enacted, could be applied, possibly on a retroactive basis, at any time. This
  discussion is for general information only and it is not intended to be, nor
  should it be construed to be, legal or tax advice to any holder or prospective
  holder of the Company's common shares and no opinion or representation with
  respect to tax consequences to any such holder or prospective holders is made.


  Accordingly, holders and prospective holders of the Company's common shares
  should consult their own tax advisors about the federal, state, local, and
  foreign tax consequences of purchasing, owning and disposing of the Company's
  common shares.

US Holders
  As used herein, a "US Holder" means a holder of the Company's common shares
  who is a citizen or individual resident (as defined under U.S. tax laws) of
  the United States, or, generally a corporation limited liability company, or a
  partnership created or organized in or under the laws of the United States or
  of any political subdivision thereof, or a trust whose income is taxable in
  the United States irrespective of source. This summary does not address the
  tax consequences to, and a US Holder does not include, persons subject to
  special provisions of federal income tax law, such as tax-exempt
  organizations, qualified retirement plans, individual retirement accounts and
  other tax-deferred accounts, financial institutions, insurance companies, real
  estate investment trusts, regulated investment companies, broker-dealers,
  non-resident alien individuals, persons or entities that have a "functional
  currency" other than the US dollar, shareholders who hold common stock as part
  of a "straddle", hedging or a conversion transaction and shareholders who
  acquired their stock through the exercise of employee stock options or
  otherwise as compensation for services. This discussion is limited to US
  Holders who hold the common shares as capital assets. This discussion does not
  address the consequences to a person or entity holding an interest in a US
  Holder or the consequence to a person of the ownership, exercise or
  disposition of any warrants, options or other rights to acquire common shares.

Distributions on Common Shares
  Subject to the discussion below at "Other Considerations", US Holders
  receiving dividend distributions (including but not limited to constructive
  dividends) with respect to the Company's common shares generally are required
  to include in gross income for United States federal income tax purposes the
  gross amount of such distributions equal to the US dollar value of each
  dividends on the date of receipt (based on the exchange rate on such date) to
  the extent that the Company has current or accumulated earnings and profits,
  without reduction for any Canadian income tax withheld from such
  distributions. Such Canadian tax withheld may be credited, subject to certain
  limitations, against the US Holder's United States federal income tax
  liability or, alternatively, may be deducted in computing the US Holder's
  United States federal taxable income by those who itemize deductions. (See
  more detailed discussion at "Foreign Tax Credit" below.) To the extent
  that distributions exceed current or accumulated earnings and profits of the
  Company, they will be treated first as a return of capital up to the US
  Holder's adjusted basis in the common shares and thereafter as gain from the
  sale or exchange of the common shares. Preferential tax rates for long-term
  capital gains are applicable to a US Holder which is an individual, estate or
  trust. There are currently no preferential tax rates for long-term capital
  gains for a US Holder which is a corporation.


  
  In the case of foreign currency received as a dividend that is not converted
  by the recipient into US dollars on the date of the receipt, a US Holder will
  have a tax basis in the foreign currency equal to its US dollar value on the
  date of receipt. Generally, any gain or loss recognized upon a subsequent sale
  or other disposition of the foreign currency, including an exchange for US
  dollars, will be ordinary income or loss.
  Dividends paid on the Company's common shares will not generally be eligible
  for the dividends received deduction provided to corporations receiving
  dividends from certain United States corporations. A US Holder which is a
  corporation may, under certain circumstances, be entitled to a 70 per cent
  deduction of the United States source portion of dividends received from the
  Company (unless the Company qualifies as a "foreign personal holding company"
  or a "passive foreign investment company," as defined below) if such US Holder
  owns common shares representing at least 10 per cent of the voting power and
  value of the Company. The availability of this deduction is subject to several
  complex limitations which are beyond the scope of this discussion.

Foreign Tax Credit
  
  A US Holder who pays (or has withheld from distributions) Canadian income tax
  with respect to the ownership of the Company's common shares may be entitled,
  at the option of the US Holder, to either a deduction or a tax credit for such
  foreign tax paid or withheld. Generally, it will be more advantageous to claim
  a credit because a credit reduces United States federal income tax on a
  dollar-for-dollar basis, while a deduction merely reduces the taxpayer's
  income subject to tax. This election is made on a year-by-year basis and
  generally applies to all foreign taxes paid by (or withheld from) the US
  Holder during that year. There are significant and complex limitations which
  apply to the credit, among which is the general limitation that the credit
  cannot exceed the proportionate share of the US Holder's United States income
  tax liability that the US Holder's foreign source income bears to his/her or
  its worldwide income. In the determination of the application of this
  limitation, the various items of income and deduction must be classified into
  foreign and domestic sources. Complex rules govern this classification
  process. In addition, this limitation is calculated separately with respect to
  specific classes of income such as "passive income," "high withholding tax
  interest," "financial services income," "shipping income," and certain other
  classifications of income. The availability of the foreign tax credit and the
  application of the limitations on the credit are fact specific, and holders
  and prospective holders of the Company's common shares should consult their
  own tax advisors regarding their own circumstances.

Disposition of Common Shares
  Subject to the discussion below at "Other Considerations", a US Holder will
  generally recognize gain or loss upon the sale or other disposition of common
  shares equal to the difference, if any, between (i) the amount of cash plus
  the fair market value of any property received, and (ii) the shareholder's tax
  basis in the Company's common shares. This gain or loss will be capital gain
  or loss if the common shares are a capital asset in the hands of the US Holder
  (and if the stock is not "Section 306 Stock"), which will be a long-term
  capital gain or loss if the common shares of the Company are held for more
  than one year and which may be entitled to a preferential tax rate. Deductions
  for net capital losses generally may be carried over to be used in later tax
  years until such net capital loss is thereby exhausted. For US Holders which
  are corporations (other than corporations subject to Subchapter S of the
  Code), generally an unused net capital loss may be carried back three years
  from the loss year and carried forward five years from the loss year to be
  offset against capital gains until such net capital loss is thereby exhausted.

Other Considerations
  In
  the following circumstances, the above sections of this discussion may not
  describe the United States federal income tax consequences resulting from the
  holding and disposition of common shares:

Foreign Personal Holding Company
  If at any time during a taxable year more than 50 per cent of the total
  combined voting power or the total value of the Company's outstanding shares
  is owned, directly or indirectly (including by attribution), by five or fewer
  individuals who are citizens or residents of the United States and 60 per cent
  or more of the Company's gross income for such year (50 per cent in subsequent
  years) was derived from certain passive sources (e.g., dividends, interests,
  rents, royalties, etc.), the Company may be treated as a "foreign personal
  holding company." In that event, US Holders that hold common shares would be
  required to include in gross income for such year their allocable portions of
  the Company's taxable income to the extent the Company does not actually
  distribute such income.

Foreign Investment Company
  
  If 50 per cent or more of the combined voting power or total value of the
  Company's outstanding common shares are held, directly or indirectly
  (including through attribution), by citizens or residents of the United
  States, United States domestic partnerships or corporations, or estates or
  trusts other than foreign estates or trusts (as defined by Code Section
  7701(a) (31)), the Company is found to be engaged primarily in the business of
  investing, reinvesting, or trading in securities, commodities, or any interest
  therein, and certain other conditions are met, the Company may be treated as a
  "foreign investment company" as defined in Section 1246 of the Code, causing
  all or part of any gain realized by a US Holder selling or exchanging common
  shares to be treated as ordinary income rather than capital gain.

Passive Foreign Investment Company
  As a foreign corporation with US Holders, the Company could potentially be
  treated as a passive foreign investment company ("PFIC"), as defined in
  Section 1297 of the Code, depending upon the percentage of the Company's
  income which is passive, or the percentage of the Company's assets which is
  producing passive income. Generally, on certain distributions and on
  disposition, US Holders owning common shares of a PFIC are subject to a
  special tax regime imposing the highest U.S. ordinary income tax rate plus an
  interest charge based on the value of deferral of tax for the period during
  which the common shares of the PFIC are owned. However, if the US Holder makes
  a timely election to treat a PFIC as a qualified electing fund ("QEF") with
  respect to such shareholder's interest therein, the above-described rules
  generally will not apply. Instead, the electing US Holder would include
  annually in gross income his/her or its pro rata share of the PFIC's ordinary
  earnings and net capital gain regardless of whether such income or gain was
  actually distributed. A US Holder making a QEF election can, however, under
  certain circumstances elect to defer the payment of United States federal
  income tax on such income inclusions subject to an interest charge on the
  amount of deferred taxes. Special rules apply to US Holders who own their
  interests in a PFIC through intermediate entities or persons. In addition,
  subject to certain limitations, US Holders owning (actually or constructively)
  marketable stock in a PFIC will be permitted to elect to mark that stock to
  market annually, rather than be subject to the tax regime described above.
  Amounts included in or deducted from income under this alternative (and actual
  gains and losses realized upon disposition, subject to certain limitations)
  will be treated as ordinary gains or losses.


  
  The Company has not determined whether it is or has been a PFIC in earlier
  years. US Holders of the Company's common shares should consult with their own
  tax advisor concerning the possible application of the PFIC provisions in
  their circumstances.

Controlled Foreign Corporation
  If
  more than 50 per cent of the voting power of all classes of stock or the total
  value of the stock of the Company is owned, directly or indirectly (including
  through attribution), by citizens or residents of the United States, United
  States domestic partnerships and corporations or estates or trusts other than
  foreign estates or trusts, each of whom own 10 per cent or more of the total
  combined voting power of all classes of stock of the Company ("United States
  Shareholder"), the Company is a "controlled foreign corporation". This
  classification generally results in the inclusion of certain income of a CFC
  in the US Shareholders' US income as a deemed dividend. In addition, under
  Section 1248 of the Code, gain from the sale or exchange of stock by a holder
  of common shares who is or was a United States Shareholder at any time during
  the five year period ending with the sale or exchange may be treated as
  ordinary dividend income.

  FINANCIAL STATEMENTS
  The financial statements required by Item 17 appear commencing on the next
  page: Consolidated Financial Statements 
            (Expressed in United States dollars)MICROMEM TECHNOLOGIES INC.(A DEVELOPMENT STAGE COMPANY)October 31, 2002  AUDITORS' REPORT  To the Shareholders of
  Micromem Technologies Inc. We have audited the consolidated balance sheet of Micromem
  Technologies Inc. (a Development Stage Company) as at October 31, 2002 and the
  consolidated statements of operations and deficit, cash flows and
  shareholders' equity for the year ended October 31, 2002 and for the
  cumulative period from September 3, 1997 to October 31, 2002. These financial
  statements are the responsibility of the Company's management. Our
  responsibility is to express an opinion on these financial statements based on
  our audit.






  
  We conducted our audit in accordance with Canadian and
  United States generally accepted auditing standards. Those standards require
  that we plan and perform an audit to obtain reasonable assurance whether the
  financial statements are free of material misstatement. An audit includes
  examining, on a test basis, evidence supporting the amounts and disclosures in
  the financial statements. An audit also includes assessing the accounting
  principles used and significant estimates made by management, as well as
  evaluating the overall financial statement presentation.






  
  In our opinion, these consolidated financial statements
  present fairly, in all material respects, the financial position of the
  Company as at October 31, 2002 and the results of its operations and its cash
  flows for the year then ended and for the cumulative period from September
  3,1997 to October 31, 2002 in accordance with Canadian generally accepted
  accounting principles.






  
  As discussed in note 3 to the consolidated financial
  statements, during 2002 the Company changed its method of accounting for
  patents and trademarks.






  
  The financial statements as at October 31, 2001 and for the
  year then ended and for the cumulative period from September 3, 1997 to
  October 31, 2001 were audited by other auditors who expressed opinions without
  reservation on those statements in their reports dated December 20, 1999 and
  November 16, 2001. Toronto, Canada,
      January 27, 2003.
      /s/ Ernst & Young LLPChartered Accountants  COMMENTS BY AUDITORS FOR U.S. READERS ON CANADA-U.S. REPORTING DIFFERENCE  In the United States, reporting standards for auditors
  require the addition of an explanatory paragraph (following the opinion
  paragraph) when the financial statements are affected by conditions and events
  that cast substantial doubt on the Company's ability to continue as a going
  concern, such as those described in note 2 to the consolidated financial
  statements. Our report to the shareholders dated January 27, 2003 is expressed
  in accordance with Canadian reporting standards which do not permit a
  reference to such events and conditions in the auditors' report when these are
  adequately disclosed in the consolidated financial statements.  Toronto, Canada,

MICROMEM TECHNOLOGIES INC.
(A DEVELOPMENT STAGE COMPANY)  Notes to
Consolidated Financial Statements (Expressed in United States
dollars)  October 31, 2002 1.     Nature of Business: Micromem
Technologies Inc. ("Micromem"
or the "Company") is a corporation incorporated under the laws of the
Province of Ontario, Canada. By Articles
of Amendment dated January 14, 1999, the Company changed its name from
Avanticorp International Inc. to Micromem Technologies Inc.
On January 11, 1999, the Company
acquired all the outstanding shares of Pageant Technologies Inc.
("Pageant"), a company subsisting under the laws of Barbados.
This acquisition, as described in note 3(b),
was recorded as a reverse takeover under Canadian generally accepted accounting
principles (“Canadian GAAP”).

The Company
currently operates in a single segment as a developer of non-volatile magnetic
memory technology. To October 31, 2002, the Company has not generated
significant revenue and is devoting substantially all its efforts to the
development of its technologies. Accordingly,
for financial reporting purposes, the Company is a development stage enterprise
and, through its wholly-owned subsidiaries, is engaged in the development and
testing of its non-volatile memory technologies. 2.      Going Concern: These consolidated financial statements have been prepared on the
"going concern" basis, which presumes that the Company will be able
to realize its assets and discharge its liabilities in the normal course of
business for the foreseeable future.

The Company has
incurred substantial losses in its development stage and is still in the
development stage.  It will be necessary to raise additional funds for the
continuing development, testing and commercial exploitation of its
technologies.  The sources of these funds have not yet been
identified and there can be no certainty that sources will be available in the
future.

The Company's ability to continue as a
going concern is dependent upon completing the development of its technology for
a particular application, achieving profitable operations, obtaining additional
financing, and successfully bringing its technologies to the market. The
outcome of these matters cannot be predicted at this time. The consolidated financial statements have
been prepared on a going concern basis and do not include any adjustments to
the amounts and classifications of the assets and liabilities that might be
necessary should the Company be unable to continue in business. MICROMEM TECHNOLOGIES INC.
(A DEVELOPMENT STAGE COMPANY) Notes to Consolidated Financial Statements

(Expressed
in United States dollars)



October 31, 20023.     Summary of significant accounting
policies:

These
consolidated financial statements have been prepared in accordance with
Canadian GAAP and are stated in United States dollars. These principles are also in conformity in
all material respects with United States generally accepted accounting
principles ["U.S. GAAP"] except as described in note 17 to the
consolidated financial statements. The
most significant accounting policies are as follows:

(a) Principles of consolidation

These consolidated financial statements include
the accounts of the Company and its wholly-owned subsidiaries, Memtech
International Inc., Memtech International (USA) Inc., Micromem Technologies
B.V., Micromem Technologies S.p.A., Pageant Technologies Inc. and Pageant
Technologies (U.S.A.) Inc. All
significant intercompany balances and transactions have been eliminated upon
consolidation.

(b) Basis of presentation:
  On January 11, 1999, the Company issued 32,000,000 common shares
and 1,000,000 warrants to acquire all of the issued and outstanding shares of
Pageant. On that date, the total number
of the Company shares outstanding was 3,980,643 shares. As a result of this transaction, the
shareholders of Pageant owned 88.9% of the outstanding common shares of the
Company and, accordingly, the purchase of Pageant was accounted for as a
reverse takeover transaction.

Application of reverse takeover accounting results in the following:

(i)  the consolidated financial
statements of the combined entity are issued under the name of the legal
parent, Micromem, but are considered a continuation of the financial statements
of Pageant, the legal subsidiary;

(ii)  as Pageant is deemed to be
the acquirer for accounting purposes, its assets and liabilities are included in
the consolidated financial statements at their historical carrying values;

    (iii)   
the
comparative financial statements for the period from September 3, 1997 to
October 31, 1998 are those of Pageant;
  MICROMEM TECHNOLOGIES INC.(A DEVELOPMENT STAGE COMPANY)  Notes to
Consolidated Financial Statements (Expressed in United States
dollars) October 31, 2002 3.     Summary of significant accounting
policies (continued): (iv) control of the assets and operations of the
Company is deemed to be acquired by Pageant effective January 11,
1999. For purposes of this transaction,
the deemed consideration is $549,140 ascribed to the net assets of the Company
outstanding immediately prior to the business combination; and

(v)  Pageant became a wholly-owned subsidiary of
the Company. For accounting purposes, at
January 11, 1999, the outstanding shares of the Company, the continuing
consolidated entity, consisted of the number of Micromem Shares issued to that
date with an assigned value equal to the share capital of the continuing
consolidated entity at that date as computed below.

The transaction
was accounted for by the purchase method with the results of operations
included in the financial statements from the date of acquisition. Details of the Company’s net assets acquired
and the assigned fair values of net assets at acquisition are as follows:  Cash
    $
    168,084Non-cash current assets
    
    115,629Investments
    
    371,471655,184Less current liabilities
    
    106,044Assigned fair value of net assets
    $
    549,140 (c) Use of estimates: The preparation of consolidated financial statements in conformity
with Canadian GAAP requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities, the disclosure of
contingent assets and liabilities at the date of the consolidated financial
statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could
differ from those estimates. (d) Cash
and cash equivalents: Cash and cash
equivalents consist of all bank accounts and all highly liquid investments with
original maturities of three months or less at the date of purchase.  MICROMEM TECHNOLOGIES INC.(A DEVELOPMENT STAGE COMPANY)  Notes to
Consolidated Financial Statements (Expressed in United States
dollars) October 31, 2002 3.     Summary
of significant accounting policies (continued): (e) Capital
assets: Capital assets
are recorded at cost less accumulated amortization. Amortization is provided on capital assets on
a straight-line basis for a period of up to three years. Capital assets are reviewed for impairment
whenever events or changes in circumstances indicate that the carrying amount
may not be recoverable. When
circumstances dictate, an impairment loss is calculated as equal to the excess
of the carrying value of the assets over their undiscounted estimated future
net cash flow. (f)  Patents
and trademarks: Effective
November 1, 2001, the Company changed its accounting policy for patents and
trademarks to be recorded at cost less accumulated amortization which is
provided on a straight-line basis over ten years. In prior years the
Company accounted for its patents and trademarks at cost and amortization was
to commence on an appropriate basis to charge off the cost over the future benefit,
not exceeding the legal life, when sales commence. There was no material impact on prior years
consolidated financial statements and accordingly, the comparative consolidated
financial statements have not been restated.

For the year ended October 31, 2002, the change in accounting
policy resulted in an increase in amortization expense and net loss by $31,338
and there was no material impact on net loss per share.

Patents and
trademarks are reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount may not be recoverable. When circumstances dictate, an impairment
loss is calculated as equal to the excess of the carrying value of the assets
over their undiscounted estimated future net cash flow. (g) Research and development expenses: Research costs are expensed in the period incurred.  Development expenses are expensed as incurred
unless they meet the criteria for deferral and amortization under Canadian GAAP. The Company has determined that no
development costs have met these criteria at the financial reporting date.  MICROMEM TECHNOLOGIES INC.(A DEVELOPMENT STAGE COMPANY)  Notes to
Consolidated Financial Statements (Expressed in United States
dollars)  October 31, 2002  3.     Summary
of significant accounting policies (continued): (h)      Stock-based compensation:

  The Company has a stock-based compensation plan, which is
described in note 9. Stock-based compensation is recognized by the intrinsic
value method, whereby compensation is recorded to the extent that the exercise
price is not based on the market value of the Company’s common shares at the
date of grant. Any compensatory benefit
recorded is recognized initially as deferred compensation in the consolidated
statements of shareholders’ equity, and then charged against income over the
contractual or vesting period.

(i)       Income
taxes:

  The Company accounts for income taxes by the asset and liability
method. Under the asset and liability
method, future tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Future tax assets and liabilities
are measured using substantively enacted tax rates and laws that are expected
to apply when the asset is realized or the liability settled. To the extent that it is not considered to be
more likely than not that a future income tax asset will be realized, a
valuation allowance is provided.

(j)       Foreign currency translation:

  The functional
currency of the Company is the United States dollar. The Company's wholly-owned
subsidiaries are integrated foreign operations and therefore, the Company uses
the temporal method whereby monetary assets and liabilities are translated into
Canadian dollars using the rate of exchange at the consolidated balance sheet
dates. Non-monetary assets and
liabilities are translated at historical rates. 
Revenue and expenses are translated at rates of exchange prevailing at
the transaction dates. Gains or losses
resulting from translation are included in the determination of net loss for
the period.  MICROMEM TECHNOLOGIES INC.(A DEVELOPMENT STAGE COMPANY)  Notes to
Consolidated Financial Statements (Expressed in United States
dollars)  October 31, 2002 3.      Summary of significant accounting
policies (continued): The Company's monetary assets and liabilities denominated in
foreign currencies are translated into United States dollars at the exchange
rate in effect at the consolidated balance sheet dates. Non-monetary assets and liabilities that are
denominated in currencies other than United States dollars are translated into
United States dollars using the historical rate of exchange in effect on the
date the transaction occurred. Revenue
and expense items are translated at the exchange rate in effect at the date of
the transaction. Resulting exchange
gains or losses are included in net loss for the period.  MICROMEM TECHNOLOGIES INC.(A DEVELOPMENT STAGE COMPANY)  Notes to Consolidated
Financial Statements (Expressed in United States
dollars)  October 31, 2002 4.       Acquisition
of royalty rights and remaining interest in technology from Estancia Limited On December 9, 2000, the Company and
its subsidiary, Pageant, entered into an Asset Purchase Agreement (the
“Agreement”) with Estancia Limited (“Estancia”) and Richard Lienau (“Lienau”) to purchase the
remaining 50% interests in the patents which the Company did not own, and a 40%
gross profit royalty (“Estancia Royalty”), in respect of certain ferromagnetic memory technology known as VEMRAM
(previously known as MAGRAM) and covered by U.S. Patent #5,295,097 and the
related patent applications (the “VEMRAM Patents”) described in the agreement
and all rights (the “VEMRAM Technology”) held by Estancia and Lienau under the
Joint Ownership and Licensing Agreement dated September 17, 1997 among
Estancia, Lienau and Pageant. Under the terms of the Agreement:

(i)   the Company would be required to pay a
maximum purchase price of $50,000,000 to Estancia as follows:

(a)     $10,000,000 was
paid on closing (after receipt of regulatory approvals), in the form of
$8,000,000 in common shares of the Company (“Micromem Shares”) (based on the
close price on the closing date) and $2,000,000 in cash;

(b)     $20,000,000 if and
when either (i) certification is received from Honeywell Federal Manufacturing
& Technologies (“Honeywell”) and that fully integrated, randomly
addressable memory matrices of the Technology have met certain stipulated
performance standards, or (ii) the Company or any of its affiliates executes a
definitive agreement for the sale or licensing of the Technology to an arm’s
length third party for any commercial purposes other than testing or evaluation
of the Technology; payable in the form of cash and Micromem Shares to be
determined by Pageant provided that a minimum of 50% of the $20,000,000 shall
be paid in Micromem Shares valued at the close of trading on the date of
receipt of such certification, sale or licensing; and

(c)     $20,000,000 if and
when the Company or any of its affiliates executes a definitive agreement for
the sale or licensing with respect to any technology (including the Technology)
owned by the Company to an arm’s length third party for any commercial purposes
other than testing or evaluation of the technology, payable in the form of cash
and Micromem Shares to be determined by Pageant provided that a minimum of 50%
of the $20,000,000 shall be paid in Micromem Shares valued at the close of
trading on the date of execution of such sale or licensing.  MICROMEM TECHNOLOGIES INC.(A DEVELOPMENT STAGE COMPANY)  Notes to
Consolidated Financial Statements (Expressed in United States
dollars)  October 31, 2002   4.       Acquisition
of royalty rights and remaining interest in technology from Estancia Limited Limited (continued): (ii)  In
the event that the amounts contemplated by 4(i)(b) and/or (c) above are not
payable to Estancia by the third anniversary date of the closing date and
provided that Estancia and Lienau are not in material breach of the terms and
conditions of this agreement, Micromem shall be deemed to have conveyed and
agreed, as of such date, and there shall automatically revert, without further
action and notwithstanding any recordation requirements, to Estancia:

  (a)  an
undivided interest equal to 50% of the percentage determined by dividing (i)
the remaining unpaid amount due pursuant to 4(i)(b) and/or (c) above by (ii)
$50,000,000 (the “Final Payment Percentage Balance”) in the VEMRAM Patents; and

(b)  an
undivided interest (“Royalty”) equal to 40% of the Final Payment Percentage
Balance in:

(1)   the gross profit, less expenses
agreed to by the parties, for each license of the VEMRAM Patents sold or
otherwise transferred by Pageant; and

(2)   the amount of all royalties received
by Pageant as a result of the license or sale of the VEMRAM Patents less
reasonable expenses directly related to obtaining of said royalties.

Estancia has a first charge security interest against the assets
of Pageant’s wholly-owned subsidiary which holds a 40% interest in the VEMRAM
Patents and a 32% interest in the Royalty.

The Company paid $2,000,000 in cash and issued 2,007,831 shares,
being the equivalent of $8,000,000, the first installment payable under the
terms described above, on approval by its shareholders in the annual
shareholder meeting held on March 14, 2001. The amount of $10,000,000 paid in the form of
cash and shares, has been recorded as royalty rights in these consolidated
financial statements. During fiscal
2002, the amount was written-down to nil (note 11).

The
consideration noted in note 4(i)(b) and (c) above will be recorded when the
milestones triggering the Company’s obligations to pay said consideration, as
described in the agreement, have been achieved.

10.     Contributed surplus:

> Ataraxia Corp., the former parent
> company of Pageant, forgave $544,891 of indebtedness it was owed during fiscal
> year 1999.  This forgiven debt was treated as contributed surplus, a
> separate component of shareholders' deficiency, as this balance was between
> related parties.

11.    
Restructuring and write-down of royalty rights:

> On July 29, 2002, the Company
> restructured its operations by closing its research and development facility and
> adopted a plan to focus its current resources to outsource its research and
> development activities as described in note 14 (a).  No major costs were
> associated with this restructuring.  The Company is still at the research
> and development stage.  The development of this technology is contingent
> upon raising additional funds.  Currently there is no assurance that
> Micromem will be able to raise such funds.
> As a result of the restructuring, the
> Company determined that there was significant uncertainty that any amounts that
> would have been payable to Estancia in the foreseeable future in respect of the
> Estancia Royalty (that was purchased by Pageant under the Asset Purchase
> Agreement). Accordingly the Estancia Royalty rights acquired in the amount of
> $10,000,000 were written off in the statements of operations and deficit.

taxes:

Contingencies:

> Pageant Technologies (U.S.A.) Inc. has
> been named as a defendant in legal actions relating to tenant improvements on a
> leased property, including an action claiming dues of approximately $880,000
> alleging breach of contract under a construction contract entered into by Clear
> Blue Laboratories, Inc. [“Clear Blue”].  The landlord of the property is
> also claiming damages from Pageant Technologies (U.S.A.) Inc.  Pageant
> Technologies (U.S.A.) Inc. assigned its rights under the lease to Clear Blue,
> however Pageant Technologies (U.S.A.) Inc. is allegedly obligated to pay the
> lease payments should the assignee default under the contract.  The
> landlord is claiming damages of approximately $887,000.
> The outcome of these actions is
> uncertain and Pageant Technologies (U.S.A.) Inc. is vigorously defending all
> actions in which it is named as a defendant.  It is, therefore, not
> possible to provide an estimate of the financial effects, if any, of the
> actions.  No losses related to these actions have been accrued in these
> consolidated financial statements.  It is possible that the outcome of
> these claims could represent a material amount.
> In the normal course of business, the
> Company and its subsidiaries are involved in various legal actions.  In
> management's opinion, the ultimate disposition of these actions, individually or
> in aggregate, will not have a material adverse effect on the financial condition
> of the Company.

17.       Reconciliation between Canadian GAAP and U.S. GAAP (continued):

For the purposes of
reporting under U.S. GAAP, companies are required under SFAS 123 to calculate
and disclose on a pro formabasis, the compensation expense related to
the fair value of the stock options granted during the year in the notes to the
consolidated financial statements.  Accordingly, for the purpose of
reporting under U.S. GAAP, the Company's net loss applicable to common shares
and loss per common share would be increased to the pro formaamounts as
follows:

Period fromSeptember 3,1997 toOctober 31,2002

        0.21
        
        0.38
        
        1.00


There were no options granted during
2002.  The fair values of all options granted during 2001 and 2000 were
estimated as of the date of grant using the black-Scholes option pricing model
with the following assumptions:

> 2002
>       2001
>       2000Dividend yield
>       –
>       –%
>       –%Expected volatility
>       –
>       100%
>       100%Risk-free interest rate
>       –
>       3.97% - 5.52%
>       4.87% - 6.36%Expected option life
>       –
>       2 - 3 years
>       1 - 4 years

The effects of the
pro forma disclosures are not likely to be representative of the effects on
reported net income for future years, because options vest over several years
and additional awards may be made in future years.
