                                  RISK FACTORS

       Before you invest in the offered securities described in this prospectus,
you should be aware that such  investment  involves  the  assumption  of various
risks. You should consider  carefully the risk factors  described below together
with all of the other information  included in this prospectus before you decide
to purchase the offered securities.

We have  not  generated  any  substantial  operating  revenues  and may not ever
generate substantial revenues.
--------------------------------------------------------------------------------

         To date, we have not generated substantial revenues from operations. We
have  not  generated  revenues  from the jig and have  scaled  back  development
efforts for the  foreseeable  future.  We have  generated only $141,576 of sales
revenues as of  September  30, 2002 and have not  completed  exploration  of the
Tennessee  mineral  property.  We can  provide  no  assurance  that we will ever
generate revenues from the jig or the Tennessee mineral property or that we will
generate substantial revenues from the titanium processing technology.

We may continue to experience significant losses from operations.
-------------------------------------------------------------------------------

         We have  experienced a loss from  operations in every fiscal year since
our inception. Our losses from operations in 2000 were $6,647,367 and our losses
from  operations in 2001 were  $6,021,532.  We will continue to experience a net
operating loss until, and if, the titanium processing technology, the jig and/or
the Tennessee mineral property begin generating  significant  revenues.  Even if
any or all such products or projects begin generating  significant revenues, the
revenues may not exceed our costs of production and operating  expenses.  We may
not ever realize a profit from operations.

We may not be able to raise sufficient capital to meet future obligations.
--------------------------------------------------------------------------------

         As of September 30, 2002, we had $306,061 in cash and a working capital
deficit  of  $2,181,380.  Although  we  have  raised  additional  capital  since
September  30, 2002,  we do not expect that this  capital,  when  combined  with
projected  revenues  from  nanoparticle  sales,  will be  sufficient to fund our
ongoing  operations.  Accordingly,  we will need to raise significant amounts of
additional  capital in the future in order to sustain our ongoing operations and
continue  the testing and  additional  development  work  necessary to place the
titanium processing technology into continuous  operation.  In addition, we will
need additional capital for testing and development of the jig or exploration of
the Tennessee mineral property.  If we determine to construct and operate a mine
on the Tennessee mineral property,  we will need to obtain a significant  amount
of  additional  capital  to  complete  construction  of the  mine  and  commence
operations.

         We may not be able obtain the amount of  additional  capital  needed or
may be forced to pay an extremely high price for capital.  Factors affecting the
availability and price of capital may include the following:
--------------------------------------------------------------------------------


                                       2


o    market factors affecting the availability and cost of capital generally;
o    our financial results;
o    the amount of our capital needs;
o    the market's perception of nanotechnology and/or minerals stocks;
o    the economics of projects being pursued;
o    industry  perception  of our ability to  recover or produce  minerals  with
     the jig or  titanium  processing technology  or from the  Tennessee mineral
     property; and
o    the price, volatility and trading volume of our common shares.

If we are unable to obtain sufficient  capital or are forced to pay a high price
for capital,  we may be unable to meet future  obligations or adequately exploit
existing or future opportunities, and may be forced to discontinue operations.

We  have a  substantial  number  of  warrants,  options  and  other  convertible
securities  outstanding and may issue a significant  number of additional shares
upon exercise or conversion thereof.
--------------------------------------------------------------------------------

         As of December 1, 2002, there were outstanding  warrants to purchase up
to 10,653,506  common shares at a weighted  average  exercise price of $1.79 per
share and  options  to  purchase  up to  3,911,700  common  shares at a weighted
average  exercise  price of $3.98 per share.  The existence of such warrants and
options may hinder  future equity  offerings,  and the exercise of such warrants
and options may further dilute the interests of all shareholders.  Future resale
of the common  shares  issuable on the exercise of such warrants and options may
have an adverse effect on the prevailing market price of the common shares.

         In addition,  we have issued a Second Amended and Restated Secured Term
Note.  Under the Second  Amended and  Restated  Secured  Term Note, a conversion
right with  respect to $280,000 of  principal  accrues on each of March 1, 2003,
June 1, 2003,  September  1, 2003,  December  1, 2003 and March 1, 2004.  If the
amount that would be subject to a conversion  right is prepaid prior to the date
of accrual,  such conversion right does not accrue.  Once a conversion right has
accrued, the principal amount subject to that conversion right cannot be prepaid
unless all principal amounts not subject to a conversion right have been prepaid
in full. Each conversion right gives the holder the right to convert the subject
principal amount into common shares at a conversion price equal to the lesser of
(a)  $1.00  per share and (b) 70% of the  average  of the  closing  price of our
common  shares for the five trading  days ending on the trading day  immediately
preceding the date on which that conversion right accrued.

         In order to illustrate the relationship between the market price of our
common  shares and the issuance of common shares upon the exercise of conversion
rights that may accrue under the Second Amended and Restated  Secured Term Note,
the following table sets forth how many additional common shares would be issued
upon the exercise of such conversion rights if such conversion rights accrue and
the average of the closing  price of our common  stock for the five trading days
ending on the day before each conversion right accrues are (a) $1.43 or greater,
(b) $0.50 per share, (c) $0.25 per share,  and (d) $0.10 per share.  Such prices
are  selected  for  illustration  purposes  only and do not  reflect  our actual
estimate  of the  average  of the  closing  price of our  common  stock  for any
particular period.

                                       3





                                    $1.43 or         $0.50           $0.25             $0.10

          Shares Issuable(1)         280,000        800,000        1,600,000         4,000,000

Percentage of Outstanding(2)
               Common Shares           .9%            2.6%            5.1%             11.8%


         (1) Assumes that  shareholder  approval is obtained for the transaction
         in which we issued the Second  Amended and  Restated  Secured Term Note
         and all related  transactions,  that no principal is prepaid,  that all
         conversion rights accrue and are exercised at the same time and that no
         default  occurs and that no  penalties  or premiums  are required to be
         paid.

         (2)  Represents  percentage  of  outstanding  common  shares  following
         exchange assuming the 30,037,939 common shares  outstanding on December
         1, 2002 are outstanding on the date of conversion.

         The  potential  accrual of such  conversion  rights  may hinder  future
equity  offerings,  and the  exercise of any  conversion  rights that accrue may
further dilute the interests of all shareholders. The sale in the open market of
common shares issuable upon the exercise of conversion rights may place downward
pressure  on the market  price of our common  shares.  Speculative  traders  may
anticipate the exercise of conversion  rights and, in  anticipation of a decline
in the market  price of our common  shares,  engage in short sales of our common
shares. Such short sales could further negatively affect the market price of our
common shares.

Our  competitors  may be able to raise  money  and  exploit  opportunities  more
rapidly, easily and thoroughly than we can.
--------------------------------------------------------------------------------

         We have limited financial and other resources and, because of our early
stage of development,  have limited access to capital. We compete or may compete
against entities that are much larger than we are, have more extensive resources
than we do and have an established reputation and operating history.  Because of
their size,  resources,  reputation,  history and other factors,  certain of our
competitors  may have better access to capital and other  significant  resources
than we do and, as a result, may be able to exploit  acquisition and development
opportunities more rapidly, easily or thoroughly than we can.


We have  pledged  substantial  assets to secure the Second  Amended and Restated
Secured Term Note.
--------------------------------------------------------------------------------

         We have  pledged all of the  intellectual  property,  fixed  assets and
common  stock  of  Altair  Nanomaterials,  Inc.,  our  second-tier  wholly-owned
subsidiary,  to secure  repayment of a Second Amended and Restated  Secured Term
Note with a face value of  $1,400,000  and a due date of March 31, 2004.  Altair
Nanomaterials,  Inc.  owns and operates the titanium  processing  technology  we
acquired from BHP in 1999. The Second Amended and Restated  Secured Term Note is
also  secured by a pledge of the common  stock and  leasehold  assets of Mineral
Recovery Systems,  Inc., which owns and operates our leasehold  interests in the
Camden, Tennessee area. If we default on the Second Amended and Restated Secured
Term Note, severe remedies will be available to the holder of the Second Amended
and Restated Secured Term Note,  including  immediate seizure and disposition of
all pledged assets.

                                       4


We have  issued a  $3,000,000  note to secure the  purchase  of the land and the
building where our titanium processing assets are located.
--------------------------------------------------------------------------------

         In August 2002, we entered into a purchase and sale  agreement with BHP
Minerals International Inc. to purchase the land, building and fixtures in Reno,
Nevada where our titanium processing assets are located. In connection with this
transaction,  BHP also  agreed to  terminate  our  obligation  to pay  royalties
associated  with  the  sale or use of the  titanium  processing  technology.  In
return, we issued to BHP a note in the amount of $3,000,000, at an interest rate
of 7%,  secured by the  property we acquired.  The first  payment of $600,000 of
principal plus accrued interest is due February 8, 2006.  Additional payments of
$600,000  plus  accrued  interest  are due  annually on February 8, 2007 through
2010. If we fail to make the required payments on the note, BHP has the right to
foreclose and take the property.  If this should occur,  we would be required to
relocate  our titanium  processing  assets and  offices,  causing a  significant
disruption in our business.

Operations using the titanium  processing  technology,  the jig or the Tennessee
mineral property may lead to substantial environmental liability.
--------------------------------------------------------------------------------

         Virtually any proposed use of the titanium processing  technology,  the
jig or the Tennessee  mineral  property  would be subject to federal,  state and
local  environmental  laws.  Under such laws,  we may be jointly  and  severally
liable with prior property owners for the treatment, cleanup, remediation and/or
removal of any  hazardous  substances  discovered  at any  property  we use.  In
addition,  courts or government  agencies may impose  liability for, among other
things,   the  improper   release,   discharge,   storage,   use,   disposal  or
transportation of hazardous  substances.  We might use hazardous substances and,
if we do, we will be subject to substantial risks that environmental remediation
will be required.

Certain of our experts and  directors  reside in Canada and may be able to avoid
civil liability.
--------------------------------------------------------------------------------

         We are a Canadian corporation,  and a majority of our directors and our
Canadian  legal counsel are residents of Canada.  As a result,  investors may be
unable to effect  service of process upon such persons  within the United States
and may be unable to enforce  court  judgments  against such persons  predicated
upon civil  liability  provisions  of the United States  securities  laws. It is
uncertain  whether Canadian courts would (i) enforce  judgments of United States
courts  obtained  against us or such directors,  officers or experts  predicated
upon the civil  liability  provisions of United States  securities  laws or (ii)
impose liability in original  actions against Altair or its directors,  officers
or experts predicated upon United States securities laws.

We are dependent on key personnel.
--------------------------------------------------------------------------------

         Our  continued  success  will  depend  to a  significant  extent on the
services of Dr. William P. Long, our Chief Executive  Officer,  Dr. Rudi Moerck,
our President,  and Mr. C. Patrick  Costin,  our Vice President and President of
Fine Gold and MRS. The loss or  unavailability  of Dr. Long,  Dr.  Moerck or Mr.
Costin  could  have a  material  adverse  effect  on us. We do not carry key man
insurance on the lives of Dr. Long, Dr. Moerck or Mr. Costin.

                                       5


We may issue  substantial  amounts  of  additional  shares  without  stockholder
approval.
--------------------------------------------------------------------------------

         Our Articles of  Incorporation  authorize  the issuance of an unlimited
number of common  shares.  All such  shares may be issued  without any action or
approval by our stockholders.  In addition, we have two stock option plans which
have  potential for diluting the ownership  interests of our  stockholders.  The
issuance of any  additional  common shares would further  dilute the  percentage
ownership of Altair held by existing stockholders.

The market price of our common shares is extremely volatile.
--------------------------------------------------------------------------------
         Our common shares are listed on the Nasdaq SmallCap Market.  Trading in
our common shares has been characterized by a high degree of volatility. Trading
in our common shares may continue to be characterized by extreme  volatility for
numerous reasons, including the following:

o     Uncertainty regarding the viability of the titanium processing technology,
      the jig or the Tennessee mineral property;
o     Dominance of trading in our common shares by a small number of firms;
o     Positive or negative announcements by us or our competitors;
o     Uncertainty  regarding  our ability to maintain  our listing on the Nasdaq
      SmallCap Market and/or continue as a going concern;
o     Industry  trends,  general  economic  conditions  in the United  States or
      elsewhere,  or the general  markets for equity  securities,  minerals,  or
      commodities; and
o     Speculation  by short  sellers of our common  shares or other  persons who
      stand to profit  from a rapid  increase  or  decrease  in the price of our
      common shares.

We may be delisted from the Nasdaq SmallCap Market.
--------------------------------------------------------------------------------

         Our  listing  on the Nasdaq  SmallCap  Market is  conditioned  upon our
compliance with the NASD's  continued  listing  requirements  for such market by
June 2003, including the $1.00 per share minimum bid requirement.  If the market
price for our common shares has not increased to $1.00 per share for at least 10
consecutive days by June 2003, we expect to be delisted from the Nasdaq SmallCap
Market.  Delisting  from the  Nasdaq  SmallCap  Market  may  have a  significant
negative  impact on the trading price,  volume and  marketability  of our common
shares.

We have  never  declared  a cash  dividend  and do not  intend to declare a cash
dividend in the foreseeable future.
--------------------------------------------------------------------------------

         We have never declared or paid cash dividends on our common shares.  We
currently intend to retain any future earnings,  if any, for use in our business
and,  therefore,  do not anticipate paying dividends on our common shares in the
foreseeable future.

We may be unable to exploit  the  potential  pharmaceutical  application  of our
titanium processing technology.
--------------------------------------------------------------------------------

         We do not  have  the  technical  or  financial  resources  to  complete
development  of,  and take to  market,  any  pharmaceutical  application  of our
titanium  processing  technology.  In order for  Altair to get any  significant,
long-term  benefit  from  any  potential   pharmaceutical   application  of  our
technologies, the following must occur:

                                       6


o     we must enter into an  evaluation  license  or similar  agreement  with an
      existing  pharmaceutical  company under which such company would pay a fee
      for the right to evaluate a  pharmaceutical  use of our  technology  for a
      specific period of time and for an option to purchase or receive a license
      for such use of our technology;

o     tests conducted by such pharmaceutical company would have to indicate that
      the pharmaceutical  use of our technology is safe,  technically viable and
      financially viable;

o     such  pharmaceutical  company  would  have to  apply  for and  obtain  FDA
      approval  of the  pharmaceutical  use of our  technology,  or any  related
      products, which would involve extensive additional testing; and

o     such pharmaceutical  company would have to successfully market the product
      incorporating our technology.

Although we could  receive  some  revenues in various  stages of the testing and
evaluation  of the  pharmaceutical  application  of our  technology,  we are not
expecting  to  receive  significant  revenue  unless  and  until an end  product
incorporating the technology goes to market.

We may not be able to license our technology for TiO2 pigment production.
--------------------------------------------------------------------------------

         Because of our relatively small size and limited  resources,  we do not
plan to use our titanium  processing  technology for  large-scale  production of
TiO2 pigments; we have, however,  entered into discussions with various minerals
and materials  companies  about  licensing  our  technology to such entities for
large-scale  production of TiO2 pigments. We have not entered into any long-term
licensing  agreements  with  respect  to  the  use of  our  titanium  processing
technology  for  large-scale  production  of TiO2  pigments  and can  provide no
assurance  that we will be able to enter into any such an agreement.  Even if we
enter into such agreement,  we would not receive significant  revenues from such
license until feasibility testing is complete and, if the results of feasibility
testing were negative, would not receive significant revenues at any time.

We may not be able to sell nanoparticles  produced using the titanium processing
technology.
--------------------------------------------------------------------------------

         We plan to use the  titanium  processing  technology  to  produce  TiO2
nanoparticles.  TiO2  nanoparticles  and other  products we intend to  initially
produce with the titanium processing technology generally must be customized for
a specific  application  working in cooperation  with the end user. We are still
testing and customizing our TiO2 nanoparticle  products for various applications
and have no  long-term  agreements  with end users to  purchase  any of our TiO2
nanoparticle products. We may be unable to recoup our investment in the titanium
processing  technology and titanium  processing  equipment for various  reasons,
including the following:

o     we may be unable to customize our TiO2  nanoparticle  products to meet the
      distinct needs of potential customers;

o     potential  customers may purchase from competitors because of perceived or
      actual quality or compatibility differences

                                       7


o     our  marketing  and  branding  efforts  may be  insufficient  to attract a
      sufficient number of customers; and

o     because  of our  limited  funding,  we  may  be  unable  to  continue  our
      development efforts until a strong market for nanoparticles develops.

         In  addition,  the uses for such  nanoparticles  are  limited,  and the
market  for such  nanoparticles  is  small.  In light of the  small  size of the
market,  the addition of a single  manufacturer may cause the price to drop to a
point at which we cannot produce the nanoparticles at a profit.

Our costs of production may be too high to permit profitability.
--------------------------------------------------------------------------------

         We have not produced any mineral products using our titanium processing
technology and equipment on a commercial  basis.  Our actual costs of production
may exceed those of competitors  and, even if our costs of production are lower,
competitors may be able to sell TiO2 and other products at a lower price than is
economical for Altair.

         In addition, even if our initial costs are as anticipated, the titanium
processing  equipment may break down, prove unreliable or prove inefficient in a
commercial  setting. If so, related costs, delays and related problems may cause
production of TiO2 nanoparticles and related products to be unprofitable.

We have not  completed  testing  and  development  of the jig and are  presently
focusing our resources on other projects.
--------------------------------------------------------------------------------

         We have not completed  testing of, or developed a production  model of,
any series of the jig. We do not expect to complete  testing and  development of
the jig during the coming year and have  determined to focus most of our limited
resources  on the  titanium  processing  technology.  We  may  never  develop  a
production model of the jig.

Even if we complete  development of the jig, the jig may prove  unmarketable and
may not perform as anticipated in a commercial operation.
--------------------------------------------------------------------------------

         The  designed  capacity  of the  Series  12 jig is too  small  for coal
washing, heavy minerals extraction,  and most other intended applications of the
jig,  except use in small placer gold mines or similar  operations.  Even if the
Series 12 jig is completed and performs to design  specifications  in subsequent
tests or at a  commercial  facility,  we  believe  that,  because  of its  small
capacity, the potential market for the Series 12 jig is limited.

         If we complete development of and begin marketing a production model of
the Series 30 jig, it may not prove  attractive to potential  end users,  may be
rendered obsolete by competing  technologies or may not recover end product at a
commercially  viable  rate.  Even if  technology  included in the jig  initially
proves attractive to potential end users,  performance  problems and maintenance
issues may limit the market for the jig.

                                       8


The jig faces  competition  from other  jig-like  products and from  alternative
technologies.
--------------------------------------------------------------------------------

         Various   jig-like   products  and   alternative   mineral   processing
technologies  perform many functions similar or identical to those for which the
jig is designed. Results from further tests or actual operations may reveal that
these alternative  products and technologies are better adapted to any or all of
the uses for which the jig is intended.  Moreover,  regardless  of test results,
consumers may view any or all of such  alternative  products and technologies as
technically superior to, or more cost effective than, the jig.

Certain patents for the jig have expired, and those that have not expired may be
difficult to enforce.
--------------------------------------------------------------------------------

         All of the initial  patents issued on the jig have expired,  and we are
unable to prevent competitors from copying the technology once protected by such
patents. Additional patents related to the process through which water is pulsed
through the cylindrical  screen on the jig expire beginning in 2010, and patents
for an efficiency-enhancing aspect of the cylindrical screen expire during 2018.
The cost of enforcing patents is often significant,  especially outside of North
America. Accordingly, we may be unable to enforce even our patents that have not
yet expired.

We have  suspended  examining the  feasibility  of mining the Tennessee  mineral
property and may not have working capital  sufficient to again continue  testing
efforts.
--------------------------------------------------------------------------------

         Due to a shortage of working  capital,  we have  suspended  feasibility
testing of the Tennessee mineral property.  We do not expect to obtain an amount
of  working  capital  sufficient  to  again  start  feasibility  testing  of the
Tennessee mineral property in the foreseeable future.

         Even if we again commence  feasibility testing on the Tennessee mineral
property,  we are unable to provide any  assurance  that mining of the Tennessee
mineral  property is feasible or to identify all processes that we would need to
complete  before we could commence a mining  operation on the Tennessee  mineral
property.  To the extent early feasibility  testing yields positive results,  we
expect feasibility testing to involve, among other things, the following:

o     operating  a  pilot  mining   facility  to  determine   mineral   recovery
      efficiencies and the quality of end products;
o     additional drilling and sampling in order to more accurately determine the
      quantity,  quality and  continuity  of minerals on the  Tennessee  mineral
      property;
o     examining  production  costs and the market for  products  produced at the
      pilot facility;
o     designing any proposed mining facility;
o     identifying  and  applying  for the  permits  necessary  for any  proposed
      full-scale mining facility; and
o     attempting  to  secure  financing  for  any  proposed   full-scale  mining
      facility.

Our test  production  at the  pilot  plant,  economic  analysis  and  additional
exploration activities may indicate any of the following:

o     that the Tennessee  mineral  property does not contain heavy minerals of a
      sufficient quantity, quality or continuity to permit any mining;
o     that production costs exceed anticipated revenues;


                                       9


o     that  end   products   do  not  meet  market   requirements   or  customer
      expectations;
o     that  there  is an  insufficient  market  for  products  minable  from the
      Tennessee mineral property; or
o     that mining the Tennessee  mineral  property is otherwise not economically
      or technically feasible.

         Even  if we  conclude  that  mining  is  economically  and  technically
feasible  on the  Tennessee  mineral  property,  we may be unable to obtain  the
capital, resources and permits necessary to mine the Tennessee mineral property.
Market  factors,  such as a decline  in the price  of, or demand  for,  minerals
recoverable  at  the  Tennessee  mineral  property,  may  adversely  affect  the
development  of mining  operations  on such  property.  In addition,  as we move
through the testing  process,  we may identify  additional items that need to be
researched and resolved before any proposed mining operation could commence.

We cannot  forecast the life of any potential  mining  operation  located on the
Tennessee mineral property.
--------------------------------------------------------------------------------

         We have not explored and tested the Tennessee  mineral  property enough
to establish the existence of a commercially minable deposit (i.e. a reserve) on
such property.  Until such time as a reserve is established  (of which there can
be no  assurance),  we cannot  provide an estimate as to how long the  Tennessee
mineral property could sustain any proposed mining operation.

We may be  unable to  obtain  necessary  environmental  permits  and may  expend
significant resources in order to comply with environmental laws.
--------------------------------------------------------------------------------

         In order to begin  construction and commercial  mining on the Tennessee
mineral property, we must obtain additional federal, state and local permits. We
will also be required to conform our operations to the  requirements of numerous
federal,  state and local  environmental laws. Because we have not yet commenced
design of a commercial mining facility on the Tennessee mineral property, we are
not in a position  to  definitively  ascertain  which  federal,  state and local
mining  and  environmental  laws or  regulations  would  apply  to a mine on the
Tennessee  mineral property.  Nevertheless,  we anticipate having to comply with
and/or  obtain  permits  under the Clean Air Act,  Clean Water Act and  Resource
Conservation   and  Recovery  Act,  in  addition  to  numerous  state  laws  and
regulations  before  commencing  construction  or  operation  of a  mine  on the
Tennessee mineral property.  We can provide no assurance that we will be able to
comply with such laws and  regulations or obtain any such permits.  In addition,
obtaining  such  permits  and  complying  with  such   environmental   laws  and
regulations may be cost prohibitive.

The market for  commodities  produced using the jig or at the Tennessee  mineral
property may significantly decline.
--------------------------------------------------------------------------------

         If the jig is successfully  developed and  manufactured on a commercial
basis,  we intend  to use the jig,  or lease the jig for use,  to  separate  and
recover valuable,  heavy mineral particles.  Active international  markets exist
for gold, titanium,  zircon and many other minerals potentially recoverable with
the jig. Prices of such minerals  fluctuate widely and are beyond our control. A
significant  decline in the price of minerals  capable of being extracted by the
jig could have significant negative effect on the value of the jig. Similarly, a
significant  decline in the price of  minerals  expected  to be  produced on the
Tennessee  mineral  property  could have a  significant  negative  effect on the
viability of a mine or processing facility on such property.

                  Outstanding Shares and Number of Shareholders

         As of December 1, 2002,  the number of common  shares  outstanding  was
30,037,939,  held by approximately 500 holders of record. In addition, as of the
same date, we had reserved 5,241,700 common shares for issuance upon exercise of
options that have been, or may be, granted under our employee stock option plans
and  10,653,506  common  shares for issuance  upon the  exercise of  outstanding
warrants.  In addition,  we have issued the Second Amended and Restated  Secured
Term Note, pursuant to which conversion rights may begin accruing in March 2003.

                                    Dividends

         We  have  never  declared  or  paid  dividends  on our  common  shares.
Moreover,  we  currently  intend to retain  any future  earnings  for use in our
business and,  therefore,  do not anticipate  paying any dividends on our common
shares in the foreseeable future.

                          Transfer Agent and Registrar

         The  Transfer  Agent  and  Registrar  for our  common  shares is Equity
Transfer Services, Inc., Suite 420, 120 Adelaide Street West, Toronto,  Ontario,
M5H 4C3.

                        Canadian Taxation Considerations

         Dividends  paid on common shares owned by  non-residents  of Canada are
subject to Canadian  withholding  tax. The rate of withholding  tax on dividends
under the Income Tax Act (Canada) (the "Act") is 25%. However,  Article X of the
reciprocal  tax treaty  between  Canada and the  United  States of America  (the
"Treaty")  generally  limits the rate of  withholding  tax on dividends  paid to
United States residents to 15%. The Treaty further  generally limits the rate of
withholding  tax to 5% if  the  beneficial  owner  of  the  dividends  is a U.S.
corporation which owns at least 10% of the voting shares of the company.

         If the beneficial  owner of the dividend  carries on business in Canada
through a permanent  establishment  in Canada or performs in Canada  independent
personal  services  from a fixed  base in Canada  and the  shares of stock  with
respect to which the  dividends  are paid are  effectively  connected  with such
permanent  establishment  or fixed base,  the dividends are taxable in Canada as
business  profits at rates  which may exceed the 5% or 15% rates  applicable  to
dividends that are not so connected with a Canadian  permanent  establishment or
fixed base. Under the provisions of the Treaty, Canada is permitted to apply its
domestic  law  rules  for  differentiating  dividends  from  interest  and other
disbursements.

         A capital gain  realized on the  disposition  of our common shares by a
person resident in the United States (a  "Non-resident")  will be subject to tax
under the Act if the  shares  held by the  Non-resident  are  "taxable  Canadian
property." In general,  our common shares will be taxable  Canadian  property if
the particular Non-resident used (or in the case of a Non-resident insurer, used
or held) the common  shares in carrying  on business in Canada or,  where at any
time during the five-year  period  immediately  preceding the realization of the
gain,  not less than 25% of the  issued and  outstanding  shares of any class or
series of shares of the Company were owned by the  particular  Non-resident,  by
persons with whom the particular  Non-resident did not deal at arms' length,  or


                                       13


by any combination  thereof.  If the common shares  constitute  taxable Canadian
property,  relief  nevertheless  may be  available  under the Treaty.  Under the
Treaty,  gains from the alienation of common shares owned by a Non-resident  who
has never been resident in Canada generally will be exempt from Canadian capital
gains tax if the shares do not relate to a permanent establishment or fixed base
which the  Non-resident  has or had in  Canada,  and if not more than 50% of the
value of the shares was derived from real  property  (which  includes  rights to
explore for or to exploit mineral deposits) situated in Canada.

                                 USE OF PROCEEDS

         All proceeds  from any sale of offered  shares,  less  commissions  and
other customary fees and expenses,  will be received by the selling shareholders
selling the offered  shares.  We will not receive any proceeds  from the sale of
any of the offered shares.

                                    DILUTION

         Our  unaudited  net  tangible  book  value at  September  30,  2002 was
$3,038,825, or approximately $0.12 per each of the 26,203,902 common shares then
outstanding.  Accordingly,  new  investors  who  purchase  shares  may suffer an
immediate  dilution of the  difference  between the purchase price per share and
approximately $0.12 per share.

                              SELLING SHAREHOLDERS

         All of the offered  shares are to be sold by persons  who are  existing
security  holders of Altair.  The selling  shareholders  acquired  their shares,
warrants and other rights in private  placements  of (i) the Second  Amended and
Restated  Secured Term Note,  1,500,000  common shares and a warrant to purchase
750,000  common  shares that we  completed  on November 25, 2002 (and amended on
December 4, 2002) and (ii) 1,562,500  common shares and 585,938 warrants that we
completed on November 27, 2002.

         Of the common shares offered  hereby,  3,062,500 are currently owned by
the  selling  shareholders  and  1,335,938  are  issuable  upon the  exercise of
outstanding warrants. For purposes of this prospectus,  we have assumed that the
number of shares  issuable  upon  exercise of each of the warrants is the number
stated on the face  thereof.  With  respect to the Second  Amended and  Restated
Secured Term Note, we have  registered  3,804,348  common shares,  which is 1.25
times the number of common  shares  that would be issuable  were all  conversion
rights to have accrued and then been  exercised on November 25, 2002. The actual
number of shares that will be issued upon the exercise of conversion  rights may
be greater or fewer than such number.

         The  number  of shares  issuable  upon  exercise  of the  warrants  and
conversion  rights that may accrue under the Second Amended and Restated Secured
Term Note and available for resale  hereunder is subject to adjustment and could
materially  differ from the estimated  amount  depending on the  occurrence of a
stock split, stock dividend,  or similar transaction  resulting in an adjustment
in the number of shares subject to the warrants and conversion rights.

                                       14



                  Beneficial Ownership of Selling Shareholders

         The table below sets forth, as of December 1, 2002, the following:

o     the name of each selling shareholder,
o     certain  beneficial  ownership  information  with  respect to the  selling
      shareholders,
o     the  number of shares  that may be sold from time to time by each  selling
      shareholder pursuant to this prospectus, and
o     the amount (and, if one percent or more, the  percentage) of common shares
      to be owned by each selling shareholder if all offered shares are sold.

Beneficial  ownership is determined  in accordance  with SEC rules and generally
includes  voting or investment  power with respect to securities.  Common shares
that are issuable upon the exercise of  outstanding  options,  warrants or other
purchase rights, to the extent  exercisable  within 60 days of December 1, 2002,
are treated as outstanding for purposes of computing each selling  shareholder's
percentage ownership of outstanding common shares.

             Private Placement of Shares, Warrants and Secured Note

Doral 18, LLC
-------------

         On November 25, 2002, we entered into a Note Amendment  Agreement dated
November 21, 2002,  pursuant to which,  among other  things,  (1) the  principal
amount  of an  existing  secured  term  note  held by  Doral  was  reduced  from
$2,000,000  to  $1,400,000  in exchange  for the  issuance of  1,500,000  common
shares,  and (2) the secured term note was amended to extend the  maturity  date
from March 31, 2003 to March 31, 2004.  In order to effect these  amendments  to
the Secured Term Note,  the parties  entered into a Second  Amended and Restated
Secured Term Note dated  November 21, 2002,  which  supersedes the prior secured
term note.

         The Second  Amended and Restated  Secured Term Note is in the principal
amount of $1,400,000  and is due and payable on March 31, 2004.  Interest on the
Second Amended and Restated  Secured Term Note accrues at the rate 11% per annum
and is payable monthly in arrears in cash. Under the Second Amended and Restated
Secured  Term Note,  a  conversion  right with  respect to $280,000 of principal
accrues on each of March 1, 2003, June 1, 2003,  September 1, 2003,  December 1,
2003 and March 1,  2004.  If the amount  that  would be subject to a  conversion
right is prepaid prior to the date of accrual,  such  conversion  right does not
accrue.  Once a conversion  right has accrued,  the principal  amount subject to
such conversion right cannot be prepaid unless all principal amounts not subject
to a conversion right have been prepaid in full. Each conversion right gives the
holder the right to the  convert the  subject  principal  amount into our common
shares at a conversion  price equal to the lesser of, (a) $1.00,  and (b) 70% of
the average of the closing  price of our common  shares for the five (5) trading
days ending on the trading day  immediately  preceding  the date with respect to
which such  conversion  right accrued.  The Second Amended and Restated  Secured
Term Note  includes  standard  anti-dilution  provisions  pursuant  to which the
exercise  price and number of common  shares  issuable  thereunder  are adjusted
proportionately in the event of a stock split, stock dividend,  recapitalization
or similar transaction.

         In addition,  pursuant to the Note  Amendment  Agreement,  we issued to
Doral a warrant to purchase 750,000 common shares at the exercise price of $1.00
per share at any time on or before  November  21,  2007.  The  warrants  include
standard  anti-dilution  provisions  pursuant  to which the  exercise  price and
number of common shares issuable thereunder are adjusted  proportionately in the
event of a stock split, stock dividend, recapitalization or similar transaction.

         Pursuant to a Registration  Rights Agreement entered into in connection
with the Note  Amendment  Agreement,  we agreed to  register  the re-sale of all
common shares issued under the Note  Amendment  Agreement and issuable under the
Second  Amended and  Restated  Secured  Term Note and  warrant.  If such re-sale
registration  statement  is not  effective  by March  16,  2003,  we will  incur
penalties as stated in the  Registration  Rights  Agreement,  and the failure to
cause the registration statement to be effective within 180 days of December 16,
2002 is an event of default under the Second  Amended and Restated  Secured Term
Note.

         The shares that may be offered pursuant to this prospectus  include the
1,500,000  common shares issued under the Note Amendment  Agreement,  the common
shares  issuable  upon the  exercise of the warrant to purchase  750,000  common


                                       17


shares  granted in connection  with the Note  Amendment  Agreement and 3,804,348
common shares with respect to conversion rights that may accrue under the Second
Amended and Restated  Secured Term Note.  Such 3,804,348  common shares are 1.25
times the number of common  shares  that would be issuable  were all  conversion
rights to have accrued and then been  exercised on November 25, 2002. The actual
number of shares that will be issued upon the exercise of conversion  rights may
be greater or fewer than such number.

         On November 26, 2002, the selling  shareholders listed below acquired a
total of 1,562,500 common shares, together with 585,938 Series 2002I Warrants to
purchase common shares,  for an aggregate  purchase price of $625,000 ($0.40 per
unit  comprised of one share and 0.375 Series 2002I  Warrant).  The Series 2002I
Warrants are  exercisable at $1.00 per share and expire on November 26, 2007 or,
after one year from date of issue or anytime  after the  shares are  registered,
the 180th day  following  the date the closing price of the common shares equals
or exceeds  $3.00 for 10 days,  whether  or not  consecutive.  The Series  2002I
Warrants  include  standard  anti-dilution  provisions  pursuant  to  which  the
exercise  price and number of common  shares  issuable  thereunder  are adjusted
proportionately in the event of a stock split, stock dividend,  recapitalization
or similar transaction.

         The specific  acquisitions  of each selling  shareholder  that acquired
common shares and warrants in the November 26, 2002 acquisition are as follows:

-------------------------------------------------------------------------------------------------


         The shares that may be offered pursuant to this prospectus include such
1,562,500  common  shares and the common  shares  issuable upon exercise of such
585,938 warrants.

                              PLAN OF DISTRIBUTION

         The Shares. The shares offered by this prospectus may be sold from time
to time by the  selling  shareholders,  who  consist  of the  persons  named  as
"selling shareholders" above and those persons' pledgees, donees, transferees or
other  successors  in interest.  The selling  shareholders  may sell the offered
shares on the Nasdaq  SmallCap  Market,  or  otherwise,  at market  prices or at
negotiated  prices.  They  may  sell  shares  by  one  or a  combination  of the
following:

          o   a block trade in which a broker or dealer so engaged  will attempt
              to sell the offered shares as agent, but may position and resell a
              portion of the block as principal to facilitate the transaction;


                                       18


          o   purchases  by a broker or dealer as  principal  and  resale by the
              broker or dealer for its account pursuant to this prospectus;
          o   ordinary brokerage transactions and transactions in which a broker
              solicits purchasers;
          o   an  exchange  distribution  in accordance  with the  rules of such
              exchange;
          o   privately negotiated transactions;
          o   if such a sale qualifies,  in accordance with Rule 144 promulgated
              under the Securities Act rather than pursuant to this  prospectus;
              or
          o   any other method permitted pursuant to applicable law.

         The selling  shareholders may also sell shares by means of short sales.
Short sales  involve the sale by a selling  shareholder,  usually  with a future
delivery  date,  of common  shares that the seller does not own.  Covered  short
sales are sales made in an amount not greater than the number of shares  subject
to the short seller's warrant, conversion right or other right to acquire common
shares. A selling shareholder may close out any covered short position by either
exercising  its  warrants  or  conversion  rights to  acquire  common  shares or
purchasing  shares in the open market.  In  determining  the source of shares to
close  out the  covered  short  position,  a  selling  shareholder  will  likely
consider,  among other things, the price of common shares available for purchase
in the open  market as  compared  to the price at which it may  purchase  common
shares pursuant to its warrants or conversion rights.

         Naked  short  sales are any  sales in  excess  of the  number of shares
subject  to the  short  seller's  warrant,  conversion  right or other  right to
acquire common shares.  A selling  shareholder must close out any naked position
by purchasing  shares.  A naked short position is more likely to be created if a
selling  shareholder  is  concerned  that there may be downward  pressure on the
price of the common shares in the open market.

          The existence of a significant  number of short sales generally causes
the price of the common shares to decline,  in part because it indicates  that a
number of market participants are taking a position that will profitable only if
the price of the common  shares  declines.  Purchases  to cover short sales may,
however,  increase  the  demand  for the  common  shares  and have the effect of
raising or maintaining the price of the common shares.

          In  making   sales,   brokers  or  dealers   engaged  by  the  selling
shareholders may arrange for other brokers or dealers to participate. Brokers or
dealers will receive commissions or discounts from such selling  shareholders in
amounts to be negotiated  prior to the sale. Such selling  shareholders  and any
broker-dealers  that  participate  in  the  distribution  may  be  deemed  to be
"underwriters"  within the  meaning of Section  2(11) of the  Securities  Act of
1933, and any proceeds or  commissions  received by them, and any profits on the
resale  of shares  sold by  broker-dealers,  may be  deemed  to be  underwriting
discounts and commissions.  If a selling shareholder notifies us that a material
arrangement  has been entered into with a  broker-dealer  for the sale of shares
through a block trade,  special  offering,  exchange  distribution  or secondary
distribution  or a  purchase  by a broker or dealer,  we will file a  prospectus
supplement, if required pursuant to the Securities Act of 1933, setting forth:

         o   the name of each of the participating broker-dealers,
         o    the number of shares involved,

                                       19


         o    the price at which the offered shares were sold,
         o    the  commissions  paid or discounts or concessions  allowed to the
              broker-dealers, where applicable;
         o    a statement to the effect that the  broker-dealers did not conduct
              any   investigation   to  verify  the   information   set  out  or
              incorporated by reference in this prospectus, and
         o    any other facts material to the transaction.

          General.  We are paying  the  expenses  incurred  in  connection  with
preparing and filing this prospectus and the registration  statement to which it
relates,  other than selling  commissions.  In addition,  in the event a selling
shareholder  effects  a short  sale of common  shares,  this  prospectus  may be
delivered  in  connection  with such short  sale and the shares  offered by this
prospectus  may be used to cover such short sale. To the extent,  if any, that a
selling shareholder may be considered an "underwriter" within the meaning of the
Securities  Act,  the sale of the shares by the  selling  shareholders  shall be
covered by this prospectus.

         We have not retained any  underwriter,  broker or dealer to  facilitate
the  offer  or  sale of the  offered  shares  offered  hereby.  We  will  pay no
underwriting  commissions or discounts in connection therewith,  and we will not
receive any proceeds from the sale of the offered shares.

         In order to comply  with the  securities  laws of  certain  states,  if
applicable,  the  offered  securities  will be sold in such  jurisdictions  only
through  registered  or licensed  brokers or dealers.  In  addition,  in certain
states the offered  shares may not be sold unless they have been  registered  or
qualified for sale in the applicable state or an exemption from the registration
or qualification requirement is available.

Item 15. Indemnification of Directors and Officers
--------------------------------------------------

Our Bylaws

         The  Registrant's  Bylaws provide that, to the maximum extent permitted
by law, the Registrant  shall indemnify a director or officer of the Registrant,
a former director or officer of the Registrant,  or another  individual who acts
or acted at the Registrant's  request as a director or officer, or an individual
acting in a similar capacity, of another entity,  against all costs, charges and
expenses,  including  any amount paid to settle an action or satisfy a judgment,
reasonably  incurred  by the  individual  in  respect  of any  civil,  criminal,
administrative,  investigative  or other  proceeding in which the  individual is
involved because of that association with the Registrant or other entity.

The Canada Business Corporations Act

         Section 124 of the Canada Business Corporations Act provides as follows
with respect to the indemnification of directors and officers:

         (1)  A  corporation   may  indemnify  a  director  or  officer  of  the
corporation,  a  former  director  or  officer  of the  corporation  or  another


                                       II-1


individual  who acts or acted at the  corporation's  request  as a  director  or
officer,  or an  individual  acting in a similar  capacity,  of another  entity,
against all costs,  charges and expenses,  including an amount paid to settle an
action or satisfy a judgment,  reasonably  incurred by the individual in respect
of any civil,  criminal,  administrative,  investigative  or other proceeding in
which  the  individual  in  involved   because  of  that  association  with  the
corporation or other entity.

         (2) A corporation  may advance  moneys to a director,  officer or other
individual  for the costs,  charges and expenses of a proceeding  referred to in
subsection (1). The individual shall repay the moneys if the individual does not
fulfill the conditions of subsection (3).

         (3) A corporation may not indemnify an individual  under subsection (1)
unless the individual

                  (a) acted  honestly  and in good faith with a view to the best
         interests  of the  corporation,  or,  as the case  may be,  to the best
         interests  of the  other  entity  for  which  the  individual  acted as
         director  or  officer  or in a similar  capacity  at the  corporation's
         request; and

                  (b) in the case of a  criminal  or  administrative  action  or
         proceeding that is enforced by a monetary  penalty,  the individual had
         reasonable  grounds for  believing  that the  individual's  conduct was
         lawful.

         (4) A  corporation  may with the  approval  of a  court,  indemnify  an
individual  referred to in subsection  (1), or advance  moneys under  subsection
(2), in respect of an action by or on behalf of the  corporation or other entity
to procure a judgment in its  favour,  to which the  individual  is made a party
because of the individual's  association with the corporation or other entity as
described in subsection (1) against all costs,  charges and expenses  reasonably
incurred by the  individual in connection  with such action,  if the  individual
fulfills the conditions set out in subsection (3).

         (5)  Despite  subsection  (1),  an  individual   referred  to  in  that
subsection  is  entitled to  indemnity  from the  corporation  in respect of all
costs,  charges and expenses reasonably incurred by the individual in connection
with the defense of any civil, criminal, administrative,  investigative or other
proceeding  to which the  individual  is  subject  because  of the  individual's
association with the corporation or other entity as described in subsection (1),
if the individual seeking indemnity

                  (a) was not judged by the court or other  competent  authority
         to have  committed  any  fault  or  omitted  to do  anything  that  the
         individual ought to have done; and

                  (b) fulfills the conditions set out in subsection (3).

         (6) A corporation may purchase and maintain insurance of the benefit of
an individual  referred to in subsection  (1) against any liability  incurred by
the individual

                  (a) in the  individual's  capacity as a director or officer of
         the corporation; or

                                       II-2


                  (b) in the individual's  capacity as a director or officer, or
         similar capacity, of another entity, if the individual acts or acted in
         that capacity at the corporation's request.

         (7) A corporation, an individual or an entity referred to in subsection
(1) may apply to a court for an order  approving an indemnity under this section
and the court may so order and make any further order that it sees fit.

         (8) An applicant under subsection (7) shall give the Director notice of
the application and the Director is entitled to appear and be heard in person or
by counsel.

         (9) On an application  under  subsection (7) the court may order notice
to be given to any interested person and the person is entitled to appear and be
heard in person or by counsel.

Employment Agreements With Certain Officers

         Pursuant to an  employment  agreement  with William P. Long,  the Chief
Executive Officer and a director of the Registrant, the Registrant has agreed to
assume all  liability  for and to indemnify,  protect,  save,  and hold Dr. Long
harmless from and against any and all losses, costs, expenses,  attorneys' fees,
claims, demands, liability, suits, and actions of every kind and character which
may be imposed upon or incurred by Dr. Long on account of,  arising  directly or
indirectly  from,  or in any  way  connected  with  or  related  to  Dr.  Long's
activities as an officer and member of the board of directors of the Registrant,
except as arise as a result of fraud,  felonious  conduct,  gross  negligence or
acts of moral turpitude on the part of Dr. Long. In addition,  Mineral  Recovery
Systems, Inc. ("MRS"), a wholly-owned  subsidiary of the Registrant,  has agreed
to assume all liability for and to indemnify,  protect,  save, and hold harmless
Patrick Costin (Vice  President of the Registrant and President of MRS) from and
against any and all losses, costs, expenses,  attorneys' fees, claims,  demands,
liabilities,  suits and actions of every kind and character which may be imposed
on or incurred by Mr. Costin on account of, arising directly or indirectly from,
or in any way connected with Mr.  Costin's  activities as manager,  officer,  or
director of MRS or the Registrant.

Other Indemnification Information

         Indemnification may be granted pursuant to any other agreement,  bylaw,
or  vote of  shareholders  or  directors.  In  addition  to the  foregoing,  the
Registrant  maintains  insurance  through a commercial  carrier  against certain
liabilities  which may be incurred by its directors and officers.  The foregoing
description is necessarily  general and does not describe all details  regarding
the  indemnification  of  officers,  directors  or  controlling  persons  of the
Registrant.

         Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Registrant pursuant to the foregoing provisions or otherwise, the Registrant has
been  informed  that in the opinion of the SEC such  indemnification  is against
public  policy  as  expressed  in  the  Securities   Act,  and  is,   therefore,
unenforceable.  In the  event  that a claim  for  indemnification  against  such
liabilities  (other than the payment by the  Registrant of expenses  incurred or
paid by a  director,  officer or  controlling  person of the  Registrant  in the


                                       II-3


successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

         The rights of indemnification  described above are not exclusive of any
other rights of indemnification to which the persons indemnified may be entitled
under any bylaw, agreement, vote of stockholders or directors or otherwise.

Item 17. Undertakings.
----------------------

(a)      The undersigned registrant hereby undertakes:

(1)      To file,  during any period in which  offers or sales are being made of
the  securities   registered   hereby,  a   post-effective   amendment  to  this
Registration Statement:

(i)      To  include  any  prospectus   required  by  section  10(a)(3)  of  the
Securities Act;

(ii)     To  reflect in the  prospectus  any facts or events  arising  after the
effective date of this registration statement (or the most recent post-effective
amendment  thereof)  which,  individually  or  in  the  aggregate,  represent  a
fundamental change in the information set forth in this Registration  Statement;
notwithstanding the foregoing,  any increase or decrease in volume of securities
offered (if the total dollar value of  securities  offered would not exceed that
which  was  registered)  and any  deviation  from  the  low or  high  end of the
estimated  maximum  offering  range may be reflected  in the form of  prospectus
filed with the  Commission  pursuant  to Rule 424(b) if, in the  aggregate,  the
changes in volume and price  represent  no more than a 20% change in the maximum
aggregate  offering price set forth in the  "Calculation  of  Registration  Fee"
table in the effective registration statement;

(iii)    To  include  any  material  information  with  respect  to the  plan of
distribution  not  previously  disclosed in this  Registration  Statement or any
material change to such information in this  Registration  Statement;  provided,
however,   that  paragraphs  (a)(1)(i)  and  (a)(1)(ii)  do  not  apply  if  the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a  post-effective  amendment by those  paragraphs  is
contained in periodic  reports filed with or furnished to the  Commission by the
Company  pursuant to Section 13 or Section 15(d) of the Securities  Exchange Act
of 1934 that are incorporated by reference in the registration statement.

(2)      That, for the purpose of determining any liability under the Securities
Act of 1933,  each  such  post-effective  amendment  shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

(3)      To remove from registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering.

(b)      The  undersigned  Company  hereby  undertakes  that,  for  purposes  of
determining any liability under the Securities Act, each filing of the Company's
annual  report  pursuant to Section  13(a) or Section  15(d) of the Exchange Act
that is incorporated by reference in the Registration  Statement shall be deemed
to be a new Registration  Statement  relating to the securities offered therein,
and the  offering  of such  securities  at that  time  shall be deemed to be the
initial bona fide offering thereof.

(c)      Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Company,  the  Company  has been  informed  that in the  opinion of the SEC such
indemnification is against public policy as expressed in the Securities Act, and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against  such  liabilities  (other  than the  payment by the Company of expenses
incurred or paid by a director,  officer or controlling person of the Company in
the  successful  defense of any action,  suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered,  the Company  will,  unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.
