Item 5.  Other Events.

      A.    PLACEMENT OF DEBENTURES AND ISSUANCE OF WARRANTS.

      On  December  29,  1997,  pursuant to the terms of a  Securities  Purchase
Agreement   dated   December  29,  1997  (the  "Purchase   Agreement"),   Altair
International Inc. (the "Company") completed the private placement of $5,000,000
in principal amount of 5% convertible  subordinated  debentures due December 29,
2001 (the "Initial  Debentures")  and warrants to purchase  75,000 shares of the
Company's  common  stock  ("Common  Stock") on or before  December 29, 1999 at a
price equal to $16.7188 per share (the "Initial  Warrants") to a small number of
institutional  investors  (the  "Investors")  in an  offering  exempt  from  the
registration  requirements  under the  Securities  Act of 1993,  as amended (the
"Securities  Act").  The Company has also  issued to the  placement  agent which
arranged the transaction  warrants to purchase 105,000 shares of Common Stock on
or before  December  29,  1999,  at a price  equal to  $16.7188  per share  (the
"Placement Warrants").

      Subject to certain  restrictions during the first 180 days after issuance,
the Initial  Debentures are convertible into Common Stock by the holders thereof
at any  time  prior to  maturity,  unless  previously  the  subject  of a forced
conversion or redemption by the Company.  The  Debentures  are each  convertible
into the number of shares of Common  Stock equal to the  quotient of (a) the sum
of the principal  amount of such  Debenture and all accrued but unpaid  interest
and  charges,  divided  by (b) the  lesser of (i) an amount  equal to 92% of the
average  market  price  for one share of  Common  Stock  for the five  preceding
trading days and (ii)  $14.7125.  For purposes of the  conversion  formula,  the
market  price is equal  to  closing  price  of the  Common  Stock on the  Nasdaq
SmallCap Market or the Nasdaq National Market,  as applicable,  or if the Common
Stock is not listed on either such exchange, by alternative methods described in
the  Debentures.  The holders of the Debentures  have  registration  rights with
respect to the Common  Stock as set forth in a  Registration  Rights  Agreement,
pursuant  to which the  Company  has agreed to  register  for  resale  under the
Securities Act the Common Stock  issuable upon  conversion of the Debentures and
exercise of the Warrants and Placement  Warrants within 150 days of December 29,
1997.

      In  addition,  subject  to  the  terms  and  conditions  of  the  Purchase
Agreement, the Company has the right to cause the Investors to purchase up to an
additional $5,000,000 aggregate principal amount of 5% convertible  subordinated
debentures  (the  "Put  Debentures").  If  issued,  the Put  Debentures  will be
accompanied  by warrants to  purchase  an  aggregate  number of shares of Common
Stock equal to the product of (i) 75,000  multiplied by (ii) the quotient of the
principal  amount  of  all  Put  Debentures  divided  by  $5,000,000  (the  "Put
Warrants").  The exercise price for the Put Warrants shall be an amount equal to
125% of the  closing  price per share of Common  Stock on the  Nasdaq  Small Cap
Market or the Nasdaq National  Market,  as applicable,  on the date  immediately
prior to the date the Put Warrants are issued.

      The foregoing descriptions do not purport to be complete and are qualified
by reference to the  definitive  agreements,  debentures,  and warrants filed as
Exhibits herewith.

      B.    RISK FACTORS.

      The  Company  from  time to time  makes  forward-looking  statements  that
involve  risks and  uncertainties.  The  Company's  actual  results could differ
materially  from those  anticipated  in these  forward-looking  statements  as a
result of certain factors,  including those set forth in the Company's  periodic
filings with the  Securities  and Exchange  Commission,  including the Company's
Annual Report on Form 10-K for the year ended December 31, 1996, as amended.  In
evaluating the Company's  business,  prospective  investors should consider that
actual results could differ  materially  from those  anticipated for a number of
reasons,  including,  among others,  the failure of the Company's primary asset,
the Centrifugal Jig (the "CJ"), to prove  economically  attractive to end users,
the  development  of a substitute  for the CJ by a  competitor,  the need for an
unforeseen  amount of capital to complete testing and development of the CJ, and
other unanticipated factors.

      NOW THEREFORE,  in  consideration of the premises and the mutual covenants

Initial Debentures purchased by the Buyers) of the aggregate principal amount of
Put Debentures,  which aggregate  principal amount shall not exceed  $5,000,000,

(as  indicated  opposite  such  Buyer's  name on the  Schedule of Buyers),  duly
executed on behalf of the Company  and  registered  in the name of such Buyer or
its designee.

      2.    BUYER'S REPRESENTATIONS AND WARRANTIES.
            ---------------------------------------

            Each Buyer represents and warrants with respect to only itself that:

            a.  Investment  Purpose.  Such Buyer (i) is acquiring the Debentures
and the  Warrants,  (ii) upon  conversion  of the  Debentures,  will acquire the
Conversion  Shares then issuable and (iii) upon  exercise of the Warrants,  will
acquire the Warrant  Shares then issuable  (the  Debentures,  the Warrants,  the
Conversion Shares and the Warrant Shares are collectively  referred to herein as
the  "Securities"),  for its own account for investment only and not with a view
towards,  or for resale in  connection  with,  the public  sale or  distribution
thereof,  except  pursuant to sales  registered or exempted  under the 1933 Act;
provided,  however,  that  such  Buyer  reserves  the  right to  dispose  of the
Securities  at any  time  in  accordance  with  or  pursuant  to a  registration
statement or an exemption under the 1933 Act.

            b.  Accredited   Investor  Status.  Such  Buyer  is  an  "accredited
investor" as that term is defined in Rule  501(a)(3)  of  Regulation D under the
1933 Act.

            c.  Reliance  on  Exemptions.   Such  Buyer   understands  that  the
Securities  are being offered and sold to it in reliance on specific  exemptions
from the registration requirements of United States federal and state securities
laws and that the Company is relying in part upon the truth and accuracy of, and
such Buyer's  compliance  with,  the  representations,  warranties,  agreements,
acknowledgments  and  understandings  of such Buyer set forth herein in order to

Exhibit 4.1

determine the  availability of such exemptions and the eligibility of such Buyer
to acquire such Securities.

            d.  Information.  Such  Buyer and its  advisors,  if any,  have been
furnished with all materials  relating to the business,  finances and operations
of the Company and  materials  relating to the offer and sale of the  Securities
which have been requested by such Buyer, including all SEC Documents (as defined
below).  Such  Buyer  has  received  from  the  Company  the  Private  Placement
Memorandum which contains certain risk factors relating to the Company, and such
Buyer has  reviewed  the risk  factors  set forth  therein.  Such  Buyer and its
advisors,  if any, have been afforded the opportunity to review materials and to
ask questions of the Company. Neither such inquiries nor any other due diligence
investigations  conducted  by  such  Buyer  or  its  advisors,  if  any,  or its
representatives  shall modify, amend or affect such Buyer's right to rely on the
Company's  representations  and  warranties  contained  in Section 3. Such Buyer
understands  that its  investment  in the  Securities  involves a high degree of
risk.  Such Buyer has  sought  such  accounting,  legal and tax advice as it has
considered necessary to make an informed investment decision with respect to its
acquisition of the Securities.

            e. No  Government  Review.  Such  Buyer  understands  that no United
States federal or state authority or agency or any other governmental  authority
or  agency  has  passed  on or made any  recommendation  or  endorsement  of the
Securities or the fairness or  suitability  of the  investment in the Securities
nor have such authorities  passed upon or endorsed the merits of the offering of
the Securities.

            f.  Transfer  or  Resale.  Such  Buyer  understands  that  except as
provided in the Registration Rights Agreement:  (i) the Securities have not been
and are not being  registered  under the 1933 Act or any state  securities laws,
and may not be  offered  for sale,  sold,  assigned  or  transferred  unless (A)
subsequently  registered thereunder,  (B) such Buyer shall have delivered to the
Company an opinion of counsel,  in a generally  acceptable  form,  to the effect
that such Securities to be sold,  assigned or transferred may be sold,  assigned
or  transferred  pursuant to an exemption  from such  registration,  or (C) such
Buyer provides the Company with reasonable assurance that such Securities can be
sold,  assigned or transferred  pursuant to Rule 144 promulgated  under the 1933
Act (or a successor rule thereto) ("Rule 144");  (ii) any sale of the Securities
made in  reliance on Rule 144 may be made only in  accordance  with the terms of
Rule  144  and  further,  if  Rule  144 is not  applicable,  any  resale  of the
Securities  under  circumstances in which the seller (or the person through whom
the sale is made) may be deemed to be an underwriter  (as the term is defined in
the 1933 Act) may require  compliance  with some other  exemption under the 1933
Act or the rules and  regulations of the SEC  thereunder;  and (iii) neither the
Company nor any other person is under any obligation to register such Securities
under the 1933 Act or any state  securities laws or to comply with the terms and
conditions of any exemption thereunder.

Exhibit 4.1

            g. Legends.  Such Buyer  understands  that the certificates or other
instruments representing the Debentures and the Warrants and, until such time as
the sale of the Conversion  Shares and the Warrant  Shares have been  registered
under the 1933 Act, as contemplated by the Registration  Rights  Agreement,  the
certificates  representing the Conversion Shares and the Warrant Shares,  except
as set  forth  below,  shall  bear a  restrictive  legend in  substantially  the
following form (and a stop-transfer order may be placed against transfer of such
stock certificates):

      THE SECURITIES   REPRESENTED  BY  THIS  CERTIFICATE  HAVE  NOT  BEEN
      REGISTERED  UNDER THE SECURITIES ACT OF 1933, AS AMENDED,  ANY STATE
      SECURITIES  LAWS OR ANY OTHER  SECURITIES  LAWS. THE SECURITIES HAVE
      BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE OFFERED FOR SALE,  SOLD,
      TRANSFERRED   OR  ASSIGNED  IN  THE  ABSENCE  OF  (I)  AN  EFFECTIVE
      REGISTRATION  STATEMENT FOR THE SECURITIES  UNDER THE SECURITIES ACT
      OF 1933,  AS  AMENDED,  AND THE RECEIPT OF ALL  NECESSARY  STATE AND
      FOREIGN  APPROVALS  OR (II)  AN  OPINION  OF  COUNSEL,  IN FORM  AND
      SUBSTANCE  REASONABLY  ACCEPTABLE TO ALTAIR INTERNATIONAL INC., THAT
      REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR ANY APPLICABLE  STATE
      OR FOREIGN SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 UNDER
      SAID ACT.

The legend  set forth  above  shall be removed  and the  Company  shall  issue a
certificate  without such legend to the holder of any Security  upon which it is
stamped  if,  unless  otherwise  required  by state  securities  laws,  (i) such
Security is registered  for sale under the 1933 Act and all necessary  state and
foreign approvals are obtained, (ii) in connection with a sale transaction, such
holder  provides the Company with an opinion of counsel,  in form and  substance
reasonably  acceptable  to the  Company,  to the  effect  that a public  sale or
transfer of such Security may be made without  registration  under the 1933 Act,
or (iii) such holder provides the Company with  reasonable  assurances that such
Security  can be sold  pursuant to Rule 144 without  any  restriction  as to the
number  of  securities  acquired  as of a  particular  date  that  can  then  be
immediately  sold.  Each Buyer  acknowledges,  covenants  and agrees to sell all
Securities,  including those  Securities  represented by a  certificate(s)  from
which the legend has been removed, only pursuant to (i) a registration statement
with  respect  to which  the  Buyer  has been  notified  (and the  Buyer has not
received any notice to the  contrary)  is effective  under the 1933 Act, or (ii)
advice of counsel that such sale is exempt from registration required by Section
5 of the 1933 Act.

            h. Authorization;  Enforcement.  This Agreement and the Registration

Documents have been duly executed and delivered by the Company, and (iv) each of
the  Transaction  Documents  constitutes  a valid and binding  obligation of the
Company, enforceable against the Company in accordance with its terms, except as

bankruptcy, insolvency, reorganization,  moratorium, liquidation or similar laws
relating to, or affecting  generally,  the enforcement of creditors'  rights and
remedies.

            c.  Capitalization.  As of the date hereof,  the authorized  capital

Except as  disclosed in Schedule  3(c),  as of the date of this  Agreement,  (i)
there are no outstanding options,  warrants, scrip, rights to subscribe to, call
or commitments of any character  whatsoever relating to, or securities or rights
convertible into or exchangeable for, any shares of capital stock of the Company
or  any  of its  subsidiaries,  or  contracts,  commitments,  understandings  or
arrangements  by which the Company or any of its  subsidiaries  is or may become
bound to issue  additional  shares of capital stock of the Company or any of its
subsidiaries  or  options,  warrants,  scrip,  rights to  subscribe  to, call or

or  instruments  containing  anti-dilution  or similar  provisions  that will be
triggered  by the issuance of the  Securities  pursuant to this  Agreement,  the
Debentures  or the  Warrants.  The Company has  furnished to the Buyers true and
correct copies of the Company's Articles of Incorporation,  as amended and as in
effect on the date hereof (the "Articles of  Incorporation"),  and the Company's

Exhibit 4.1

            d. Issuance of Securities.  The  Debentures are duly  authorized for

set forth in Section 4(f)) have been duly  authorized  and reserved for issuance
upon  conversion of the  Debentures.  Upon issuance in accordance with the terms
and conditions of this Agreement and the Debentures,  the Conversion Shares will
be validly issued,  fully paid and nonassessable and free from all taxes,  liens
and charges with respect to the issue thereof with the holders being entitled to
all  rights  accorded  to a  holder  of  Common  Stock.  The  Warrants  are duly
authorized for issuance and sale to the Buyers by the Company  pursuant  hereto.
Sufficient  shares  of Common  Stock  (subject  to  adjustment  pursuant  to the
Company's  covenant  set forth in Section  4(f)) have been duly  authorized  and
reserved for issuance upon exercise of the Warrants. Upon exercise in accordance
with the terms and  conditions of this  Agreement and the Warrants,  the Warrant
Shares will be validly issued,  fully paid and  nonassessable  and free from all
taxes,  liens and charges  with  respect to the issue  thereof  with the holders
being entitled to all rights  accorded to a holder of Common Stock.  To the best
knowledge of the Company,  assuming the accuracy of the  representations  of the
Buyers set forth in the  Transaction  Documents,  the issuance by the Company of
the Securities is exempt from registration under the 1933 Act.

            e.  No  Conflicts.   Except  as  disclosed  in  Schedule  3(e),  the
execution,  delivery and performance of the Transaction Documents by the Company
and the  consummation by the Company of the  transactions  contemplated  thereby
(including, without limitation, the reservation for issuance and issuance of the
Conversion  Shares and the Warrant Shares) will not (i) result in a violation of
the Articles of Incorporation or the By-laws,  (ii) conflict with, or constitute
a default (or an event which with notice or lapse of time or both would become a
default)  under,  or  give to  others  any  rights  of  termination,  amendment,
acceleration or cancellation of, any agreement, indenture or instrument to which
the  Company  or any of its  subsidiaries  is a  party,  or  (iii)  result  in a
violation of any law, rule, regulation,  by-law,  directive,  order, judgment or
decree (including federal,  state,  provincial and municipal securities laws and
regulations and the rules and regulations of the principal market or exchange on
which the Common Stock is traded or listed)  applicable to the Company or any of
its  subsidiaries or by which any property or asset of the Company or any of its
subsidiaries  is bound or  affected,  except to the extent that  matters  within
clauses  (ii) and (iii)  immediately  above  would not have a  Material  Adverse
Effect.  Except as  disclosed  in  Schedule  3(e),  neither  the Company nor its
subsidiaries is in violation of any term of or in default under (i) the Articles
of  Incorporation  or the  By-laws or their  organizational  charter or by-laws,
respectively,   or  (ii)  any  contract,  agreement,   mortgage,   indebtedness,
indenture,   instrument,  judgment,  decree  or  order  or  any  statute,  rule,
regulation,  by-law or directive  applicable to the Company or its subsidiaries,
except to the extent that such  violation  or default  would not have a Material
Adverse  Effect.  The business of the Company and its  subsidiaries is not being
conducted, and shall not be conducted, in violation of any law, ordinance, rule,
regulation,   by-law  or  directive  of  any  governmental  entity.   Except  as
specifically  contemplated by this Agreement and as required under the 1933 Act,
the Company is not required to obtain any consent, authorization or order of, or

for  it to  execute,  deliver  or  perform  any  of  its  obligations  under  or
contemplated by the Transaction  Documents in accordance with the terms thereof.
Except as disclosed in Schedule  3(e),  all  consents,  authorizations,  orders,
filings and  registrations  which the Company is required to obtain  pursuant to
the  preceding  sentence  have been obtained or effected on or prior to the date
hereof.   The  Company  and  its  subsidiaries  are  unaware  of  any  facts  or
circumstances which might give rise to any of the foregoing.  The Company is not
in violation of the listing  requirements  of the Nasdaq  SmallCap Market or the
Nasdaq National  Market,  as applicable,  as in effect on the date hereof and on
each of the Closing  Dates and is not aware of any facts which would  reasonably
lead to  delisting  of the  Common  Stock by the Nasdaq  SmallCap  Market or the
Nasdaq National Market, as applicable, in the foreseeable future.

            f. SEC Documents;  Financial  Statements.  Since March 13, 1997, the
Company has filed all reports,  schedules, forms, statements and other documents
required to be filed by it with the SEC pursuant to the  reporting  requirements
of the Securities  Exchange Act of 1934, as amended (the "1934 Act") (all of the
foregoing  and all  exhibits  included  therein  and  financial  statements  and
schedules  thereto  and  documents   incorporated  by  reference  therein  being
hereinafter  referred to as the "SEC  Documents").  The Company has delivered to
each Buyer or its respective representatives true and complete copies of the SEC
Documents.  As of their  respective  dates,  the SEC  Documents  complied in all
material  respects  with the  requirements  of the 1934  Act and the  rules  and
regulations of the SEC promulgated  thereunder  applicable to the SEC Documents,
and  none of the SEC  Documents,  at the  time  they  were  filed  with the SEC,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated  therein or necessary in order to make the statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.  As of their  respective  dates,  the  financial  statements  of the
Company  included  in the SEC  Documents  complied  as to  form in all  material
respects with  applicable  accounting  requirements  and the published rules and
regulations of the SEC with respect thereto. Such financial statements have been
prepared  in  accordance   with  generally   accepted   accounting   principles,
consistently  applied,  during  the  periods  involved  (except  (i)  as  may be
otherwise  indicated in such financial  statements or the notes thereto, or (ii)
in the case of  unaudited  interim  statements,  to the extent  they may exclude
footnotes or may be condensed or summary  statements)  and fairly present in all
material  respects the  consolidated  financial  position of the Company and its
subsidiaries  as of the dates  thereof  and the  consolidated  results  of their
operations  and cash flows for the periods then ended  (subject,  in the case of
unaudited  statements,  to  normal  year-end  audit  adjustments).  To the  best
knowledge of the Company,  no other information  provided by or on behalf of the
Company to the Buyers  which is not  included in the SEC  Documents,  including,
without limitation, information referred to in Section 2(d), contains any untrue
statement of a material  fact or omits to state any material  fact  necessary in
order to make the statements  therein,  in the light of the  circumstance  under
which they are or were made, not misleading.

Exhibit 4.1

            g. Absence of Certain Changes. Except as disclosed in Schedule 3(g),
since December 31, 1996 there has been no Material  Adverse Effect.  The Company
has not taken any steps,  and does not  currently  expect to take any steps,  to
seek  protection  pursuant to any  bankruptcy law nor does the Company or any of
its  subsidiaries  have any  knowledge or reason to believe  that its  creditors
intend to initiate involuntary bankruptcy proceedings.

            h.  Absence of  Litigation.  There is no action,  suit,  proceeding,
inquiry  or  investigation  before or by any  court,  public  board,  government
agency, self-regulatory organization or body pending or, to the knowledge of the
Company or any of its subsidiaries,  threatened against or affecting the Company
or any of its subsidiaries  that could have a Material Adverse Effect.  Schedule
3(h) contains a complete list of any pending or threatened  proceeding (known to
the  Company)  against or  affecting  the  Company  or any of its  subsidiaries,
without regard to whether it would have a Material Adverse Effect.

            i.  Acknowledgment  Regarding  Buyers'  Purchase of  Debentures  and
Warrants.  The Company acknowledges and agrees that each of the Buyers is acting
solely in the capacity of arm's length purchaser with respect to the Transaction
Documents  and  the  transactions  contemplated  thereby.  The  Company  further
acknowledges  that no Buyer is acting as a financial advisor or fiduciary of the
Company (or in any similar  capacity) with respect to the Transaction  Documents
and the  transactions  contemplated  thereby and any advice  given by any of the
Buyers or any of their respective  representatives  or agents in connection with
the Transaction  Documents and the transactions  contemplated  thereby is merely
incidental  to such  Buyer's  purchase of the  Securities.  The Company  further
represents  to each  Buyer  that  the  Company's  decision  to  enter  into  the
Transaction Documents has been based solely on the independent evaluation by the
Company and its representatives.

            j. No  Undisclosed  Liabilities.  As of the date of the most  recent
balance sheet provided in Section 3(f), the Company had no material liabilities,
except for liabilities which are reflected or reserved for on such balance sheet
in  accordance  with  generally  accepted  accounting  principles  or which  are
specifically  disclosed  in the SEC  Reports.  Since the date of the most recent
balance  sheet,  the Company has  operated in the  ordinary  course of business,
consistent  with past  practices,  and has not incurred or become subject to, or
agreed to incur or become  subject  to, any  material  liability,  except in the
ordinary course of business, consistent with past practice.

            k. No General  Solicitation.  Neither  the  Company,  nor any of its
affiliates,  nor any person  acting on its or their  behalf,  has engaged in any
form of general  solicitation  or general  advertising  (within  the  meaning of
Regulation  D under  the 1933 Act) in  connection  with the offer or sale of the
Securities.

            l. No  Integrated  Offering.  Neither  the  Company,  nor any of its
affiliates,  nor any  person  acting on its or their  behalf  has,  directly  or


                                   - 11 -




<PAGE>


Exhibit 4.1

indirectly,  made any offers or sales of any security or solicited any offers to
buy any security,  under circumstances that would require registration of any of
the  Securities  under  the 1933 Act or cause  the  offering  of the  Securities
pursuant to this Agreement to be integrated  with prior offerings by the Company
for purposes of the 1933 Act or any applicable  stockholder approval provisions,
including,  without  limitation,  under the rules and  regulations of the Nasdaq
SmallCap  Market or the Nasdaq  National  Market,  as  applicable,  nor will the
Company or any of its  subsidiaries  take any action or steps that would require
registration  of the Securities  under the 1933 Act or cause the offering of the
Securities to be integrated with other offerings.

            m.  Employee   Relations.   Neither  the  Company  nor  any  of  its
subsidiaries is involved in any union labor dispute nor, to the knowledge of the
Company or any of its subsidiaries, is any such dispute threatened.  Neither the
Company  nor any of its  subsidiaries  is a  party  to a  collective  bargaining
agreement,  and the Company and its  subsidiaries  believe that  relations  with
their  employees  are  good.  Each  of the  Company  an its  subsidiaries  is in
compliance  in all  material  respects  with the  applicable  provisions  of the
Employee  Retirement Income Security Act of 1974, as amended ("ERISA"),  and the
regulations  and  published  interpretations  thereunder.  None of the following
events has occurred or is reasonably  expected to occur that when taken together
with all other such events could  reasonably be expected to result in a Material
Adverse Effect: (i) any "reportable  event," as defined in Section 4043 of ERISA
or the  regulations  issued  thereunder,  with respect to any "employee  pension
benefit  plan" as such  term is  defined  in  Section 3 of ERISA  (other  than a
Multiemployer  Plan (as defined below)) subject to the provisions of Title IV of
ERISA or Section  412 of the  Internal  Revenue  Code of 1986,  as amended  (the
"Code"), or Section 302 of ERISA (a "Plan");  (ii) the adoption of any amendment
to a Plan that would  require  the  provision  of  security  pursuant to Section
401(a)(29) of the Code or Section 307 of ERISA; (iii) the existence with respect
to any Plan of an "accumulated funding deficiency" (as defined in Section 412 of
the Code or  Section  302 of  ERISA),  whether  or not  waived;  (iv) the filing
pursuant  to  Section  412(d)  of the  Code or  Section  303(d)  of  ERISA of an
application  for a waiver of the minimum  funding  standard  with respect to any
Plan; (v) the  incurrence of any liability  under Title IV of ERISA with respect
to the  termination of any Plan or the  withdrawal or partial  withdrawal of the
Company  or any of its  subsidiaries  from any Plan or  "multiemployer  plan" as
defined in Section 4001(a)(3) of ERISA ("Multiemployer  Plan"); (vi) the receipt
by the  Company or any of its  subsidiaries  from the Pension  Benefit  Guaranty
Corporation or a plan  administrator  of any notice relating to the intention to
terminate  any Plan or Plans or to  appoint a trustee  to  administer  any Plan;
(vii) the  receipt  by the  Company  or any of its  subsidiaries  of any  notice
concerning the imposition of liability to a Multiemployer  Plan as a result of a
complete or partial withdrawal from such  Multiemployer  Plan, as such terms are
defined in Part I of Subtitle E of Title IV of ERISA or of a determination  that
a Multiemployer  Plan is, or is expected to be, insolvent or in  reorganization,
within  the  meaning  of Title IV of  ERISA;  and  (viii)  the  occurrence  of a
"prohibited  transaction"  with  respect  to  which  the  Company  or any of its
subsidiaries is a  "disqualified  person" (within the meaning of Section 4975 of
the Code) and with  respect  to which the  Company or such  subsidiary  would be
liable for the payment of an excise tax.

Exhibit 4.1


            n.  Intellectual  Property Rights.  To the knowledge of the Company,
the Company and its  subsidiaries  own or possess adequate rights or licenses to
use all  trademarks,  trade names,  service marks,  service mark  registrations,
service  names,  patents,  patent  rights,  copyrights,   inventions,  licenses,
approvals,  governmental  authorizations,  trade  secrets  and rights to conduct
their  respective  businesses  as now  conducted,  except to the extent that the
failure to possess  such  rights or licenses  would not have a Material  Adverse
Effect.  The  Company  and its  subsidiaries  do not have any  knowledge  of any
infringement by the Company or its  subsidiaries  of any trademarks,  trade name
rights, patents, patent rights, copyrights, inventions, licenses, service names,
service marks, service mark registrations,  trade secret or other similar rights
of others,  and, except as set forth on Schedule 3(n), there is no claim, action
or proceeding  being made or brought  against,  or to the  Company's  knowledge,
being threatened against,  the Company or any of its subsidiaries  regarding any
trademarks, trade names, patents, patent rights, invention,  copyright, license,
service names, service marks, service mark registrations,  trade secret or other
infringement;  and the Company and its  subsidiaries are unaware of any facts or
circumstances  which  might give rise to any of the  foregoing,  except for such
facts and circumstances which would not have a Material Adverse Effect.

            o. Environmental  Laws. (i) The Company and its subsidiaries (x) are
in  compliance  with  any and all  applicable  foreign,  provincial,  municipal,
federal,  state and local laws and  regulations  relating to the  protection  of
human health and safety or emissions, discharges, releases, threatened releases,
removal,  remediation  or abatement of  pollutants,  contaminants,  chemicals or
industrial,  hazardous or toxic  substances or wastes into or in the environment
(including  without  limitation  air,  surface water,  ground water or land), or
otherwise used in connection  with the  manufacture,  processing,  distribution,
use,  treatment,   storage,  disposal,  transport  or  handling  of  pollutants,
contaminants,  hazardous or toxic  substances  or wastes,  as defined under such
applicable laws ("Environmental Laws"), (y) have received all permits,  licenses
or other  approvals  required  of them under  applicable  Environmental  Laws to
conduct their respective businesses and (z) are in compliance with all terms and
conditions  of any such permit,  license or approval,  except to the extent that
the  matters  within  clauses  (x),  (y) or (z) above  would not have a Material
Adverse Effect.

            (ii) There is no substance designated a "hazardous substance" by any
Environmental Law, including asbestos,  petroleum,  urea formaldehyde insulation
and petroleum  by-products  ("Hazardous  Substance")  present at any of the real
property  currently  owned or leased by the Company or any of its  subsidiaries,
except to the extent that such presence could not reasonably be expected to have
a Material Adverse Effect; and with respect to such real property, there has not
occurred (x) any release or, to the  knowledge of the  Company,  any  threatened
release of a Hazardous  Substance or (y) any  discharge  or, to the knowledge of
the Company,  threatened  discharge of any Hazardous  Substance into the ground,
surface or navigable waters which discharge or threatened discharge violates any
federal,  state,  local,  provincial,   municipal  or  foreign  laws,  rules  or
regulations concerning water pollution.

<PAGE>


Exhibit 4.1

            (iii) None of the Company or any of its  subsidiaries  has  disposed
of, transported, or arranged for the transportation or disposal of any Hazardous
Substance where such disposal,  transportation or arrangement would give rise to
liability pursuant to any Environmental Law other than any such liabilities that
could not reasonably be expected to have a Material Adverse Effect.

            (iv) There are no  underground  storage  tanks,  asbestos-containing
materials,  polychlorinated  biphenyls or urea formaldehyde insulation at any of
the  real  property  currently  owned or  leased  by the  Company  or any of its
subsidiaries in violation of any Environmental Law.

            p. Title. The Company and its subsidiaries  have good and marketable
title in fee simple to all real  property and good and  marketable  title to all
personal  property owned by them,  except to the extent that the failure to have
good and marketable title would not have a Material Adverse Effect, in each case
free  and  clear of all  liens,  encumbrances  and  defects  except  such as are
described in Schedule 3(p) or such as do not materially affect the value of such
property and do not interfere  with the use made and proposed to be made of such
property  by the  Company  or any of its  subsidiaries.  Any real  property  and
facilities held under lease by the Company or any of its  subsidiaries  are held
by them under valid,  subsisting and enforceable  leases with such exceptions as
are not material and do not interfere  with the use made and proposed to be made
of such property and buildings by the Company and its subsidiaries.

            q. Insurance.  The Company and each of its  subsidiaries are insured
by insurers of recognized financial responsibility against such losses and risks
and in such  amounts as  management  of the  Company  believes to be prudent and
customary  in the  businesses  in which the  Company  and its  subsidiaries  are
engaged.  Neither  the  Company  nor any of its  subsidiaries  has any reason to
believe that it will not be able to renew its existing insurance coverage as and
when such coverage  expires or to obtain similar  coverage from similar insurers
as may be  necessary  to continue  its  business at a cost that would not have a
Material Adverse Effect.

            r.  Regulatory  Permits.  Except as set forth on Schedule  3(e), the
Company  and  its  subsidiaries   possess  all   certificates,   authorizations,
approvals,  licenses, easements,  rights-of-way,  orders and permits ("Permits")
issued by the  appropriate  federal,  state,  provincial,  municipal  or foreign
regulatory authorities necessary to conduct their respective businesses,  except
to the extent that the failure to possess such certificates,  authorizations and
permits would not have a Material  Adverse  Effect;  and neither the Company nor
any such  subsidiary  has  received  any notice of  proceedings  relating to the
revocation or modification of any such Permit.

            s.  Compliance  With Law. Except as set forth on Schedule 3(s), each
of the Company and its  subsidiaries  has  complied  with,  has not received any
notice of violation  of, and has no knowledge of any facts which with or without
notice could  reasonably  be expected to  constitute  a violation  of, any laws,


                                   - 14 -

Exhibit 4.1

ordinances,   rules,  regulations,   by-laws,   directives,   orders,  judgment,
injunctions,  awards or decrees of any  governmental  entity  applicable  to the
Company and its subsidiaries and their  properties,  except for any violation or
failure so to comply which could not  reasonably  be expected to have a Material
Adverse Effect.

            t.  Internal  Accounting  Controls.  The  Company  and  each  of its
subsidiaries  maintain a system of internal  accounting  controls  sufficient to
provide  reasonable  assurance that (i)  transactions are executed in accordance
with  management's  general or specific  authorizations,  (ii)  transactions are
recorded  as  necessary  to  permit  preparation  of  financial   statements  in
conformity with generally accepted  accounting  principles and to maintain asset
accountability,  (iii) access to assets is  permitted  only in  accordance  with
management's   general  or  specific   authorization   and  (iv)  the   recorded
accountability  for assets is compared  with the existing  assets at  reasonable
intervals and appropriate action is taken with respect to any differences.

            u. No Materially Adverse Contracts, Etc. Neither the Company nor any
of its  subsidiaries  is  subject  to any  charter,  corporate  or  other  legal
restriction,  or any judgment,  decree,  order,  rule or regulation which in the
reasonable  judgment of the Company's  officers has or is expected in the future
to have a Material Adverse Effect.

            v. Tax Status. Except as set forth on Schedule 3(v), the Company and
each of its  subsidiaries has made or filed all federal,  state,  provincial and
municipal income and all other tax returns, reports and declarations required by
any  jurisdiction to which it is subject (unless and only to the extent that the
Company  and each of its  subsidiaries  has set  aside on its  books  provisions
reasonably  adequate for the payment of all unpaid and unreported taxes) and has
paid all taxes and other governmental  assessments and charges that are material
in  amount,  shown  or  determined  to be  due  on  such  returns,  reports  and
declarations,  except  those being  contested in good faith and has set aside on
its books provision reasonably adequate for the payment of all taxes for periods
subsequent to the periods to which such returns,  reports or declarations apply.
There are no unpaid taxes in any material amount claimed to be due by the taxing
authority of any jurisdiction,  and the officers of the Company know of no basis
for any such claim.

            w. Dilutive Effect.  The Company  understands and acknowledges  that
the number of Conversion  Shares  issuable upon conversion of the Debentures and
the number of  Warrant  Shares  issuable  upon  exercise  of the  Warrants  will
increase in certain  circumstances.  The Company further  acknowledges  that its
obligations to issue Conversion  Shares upon conversion of the Debentures and to
issue  Warrant  Shares upon  exercise of the  Warrants in  accordance  with this
Agreement,  the Debentures and the Warrants (subject to the terms and conditions
thereof),  as the case may be, are absolute and unconditional  regardless of the
dilutive effect that such issuances may have on the ownership interests of other
stockholders of the Company.

made any agreements  with any Buyers  relating to the terms or conditions of the

            y.  No  Material  Misstatement.   None  of  the  representations  or
warranties of the Company contained herein and none of the information contained

applicable  securities or "Blue Sky" laws of the states of the United States and
under applicable  securities laws of the applicable provinces and municipalities
of Canada,  and shall provide evidence of any such action so taken to the Buyers

under this Section 4(b).

            c. Reporting  Status.  Until the earlier of (i) the date as of which
the Investors (as that term is defined in the Registration Rights Agreement) may
sell all of the Conversion  Shares without  restriction  pursuant to Rule 144(k)

(A) the Investors  shall have sold all of the  Conversion  Shares and all of the
Warrant Shares and (B) none of the  Debentures and Warrants is outstanding  (the
"Registration  Period"), the Company shall file all reports required to be filed
with the SEC pursuant to the 1934 Act, and the Company  shall not  terminate its
status as an issuer required to file reports under the 1934 Act even if the 1934
Act  or the  rules  and  regulations  thereunder  would  otherwise  permit  such
termination.

            d. Use of Proceeds.  The Company will use the proceeds from the sale
of the  Debentures and the Warrants for  substantially  the same purposes and in
substantially the same amounts as indicated in Schedule 4(d).

term is defined in the Registration  Rights Agreement),  during the Registration
Period: (i) within two (2) days after the filing thereof with the SEC, a copy of
its Annual Reports on Form 10-K, its Quarterly Reports on Form 10-Q, any Current

necessary  to at all times have  authorized,  and  reserved  for the  purpose of
issuance,  no less than 150% of the number of shares of Common  Stock  needed to
provide for the issuance of the Conversion Shares and the Warrant Shares.

            g. Right of First  Refusal.  So long as an aggregate of at least ten
percent (10%) of the Debentures issued at the Closings remains outstanding,  but
subject to the exceptions  described  below,  the Company shall not enter into a
binding  agreement  or  otherwise  agree with any party for or  otherwise  issue
securities in connection with any debt financing with an equity  component,  any
equity  financing  at a fixed  discount in excess of 10% of the Market Value (as
defined  below)  of such  securities,  or any sale or  issuance  of  convertible
preferred stock ("Future  Offerings") during the period beginning on the Initial
Closing  Date and ending on and  including  the date which is 365 days after the
Initial Closing Date,  unless it shall have first delivered to Angelo,  Gordon &
Co. written notice (the "Future Offering Notice") describing the proposed Future
Offering,  including the terms and  conditions  thereof,  and providing  Angelo,
Gordon & Co. a  non-assignable  option to purchase up to the Maximum  Amount (as
defined below), as of the date of delivery of the Future Offering Notice, in the
Future  Offering  on the same  terms  and  conditions  set  forth in the  Future
Offering Notice (the  limitations  referred to in this sentence are collectively
referred to as the "Capital Raising  Limitation").  For purposes of this Section
4(g), "Market Value" shall mean the average of the closing prices on the Alberta
Stock Exchange,  the Nasdaq SmallCap  Market or the Nasdaq National  Market,  as
selected by the Company,  for the Common Stock for the ten  consecutive  trading
days immediately preceding (i) if the Company selects the Alberta Stock Exchange
as the basis for the calculation of the Market Value,  the date of the Company's
filing with the Alberta Stock  Exchange of a notice of the proposed  transaction
or the trading date  immediately  preceding  the date of such notice,  whichever
date is selected by the Alberta Stock  Exchange,  or (ii) if the Company selects

calculation of the Market Value,  the date of the Future Offering Notice (or, if
the Company is not required to send a Future Offering Notice,  the date on which
the Company enters into an agreement to sell  securities in the Future  Offering
to the purchasers thereof); provided, however, that the Company shall not select
the Alberta Stock Exchange as the basis for the  calculation of the Market Value
unless the  Company is required  to do so by rule or  regulation  of the Alberta
Stock Exchange.  For purposes of this Section 4(g),  "Maximum Amount" shall mean
the  aggregate  amount  invested  by  Angelo,  Gordon  &  Co. and its affiliates

Exhibit 4.1

in the Company pursuant to this Agreement. Angelo, Gordon & Co. can exercise its
option to participate in a Future Offering by delivering  written notice thereof
to  participate  to the Company  within ten (10)  business  days of receipt of a
Future  Offering  Notice,  which notice  shall state the quantity of  securities
being offered in the Future  Offering that it will  purchase,  up to the Maximum
Amount.  In the  event  Angelo,  Gordon  & Co.  purchases  less  than all of the
securities available in the Future Offering within the periods described in this
Section  4(g),  the Company  shall have sixty (60) days  thereafter  to sell the
securities of the Future Offering respecting which the rights of Angelo,  Gordon
& Co.  were  not  exercised  upon  terms  and  conditions  (as set  forth in the
applicable  transaction  documents) no more favorable to the purchasers  thereof
than the terms and conditions  specified in the Future Offering  Notice.  In the
event the Company has not sold such  securities  of the Future  Offering  within
such  60-day  period,  the  Company  shall  not  thereafter  issue or sell  such
securities without first offering such securities to Angelo, Gordon & Co. in the
manner provided in this Section 4(g).  Angelo,  Gordon & Co. shall purchase such
securities  on the date of  consummation  of the Future  Offering.  The  Capital
Raising  Limitation  shall not apply to (i) a loan from a commercial  bank, (ii)
any  transaction   involving  the  Company's  issuances  of  securities  (A)  as
consideration in a merger or consolidation, (B) in connection with any strategic
partnership or joint venture,  or (C) as consideration  for the acquisition of a
business,  product or license by the Company, (iii) the issuance of Common Stock
in an  underwritten  public  offering,  (iv) the  issuance  of  securities  upon
exercise or conversion of the Company's  options,  warrants or other convertible
securities  outstanding  as of the date  hereof,  (v) the  grant  of  additional
options or warrants, or the issuance of additional securities, under any Company
stock  option  or  restricted  stock  plan  for  the  benefit  of the  Company's
employees,  directors  or  consultants,  (vi) a single  issuance  by the Company
consisting  solely of Common Stock provided that the  consideration  received by
the  Company  for each such  share of Common  Stock  issued is not less than the
greater  of (A) the  closing  price of a share  of  Common  Stock on the  Nasdaq
SmallCap Market or the Nasdaq National Market,  as applicable,  on the day prior
to the date of issuance of such shares and (B) the average of the closing prices
on the Nasdaq SmallCap Market or the Nasdaq National Market, as applicable,  for
the Common Stock for the 20 consecutive  trading days immediately  preceding the
date of issuance of such shares,  or (vii) a  fixed-discount  offering of equity
securities  in which the discount  applied to such  offering does not exceed ten
percent (10%) of the Market Value of such securities. Angelo, Gordon & Co. shall
not be required to  participate  or exercise  their right of first  refusal with
respect to a  particular  Future  Offering in order to  exercise  their right of
first refusal with respect to later Future Offerings.

            h.  Listing.  The Company  shall  promptly  use its best  efforts to
secure  the  listing of all of the  Registrable  Securities  (as  defined in the
Registration  Rights  Agreement)  upon the Nasdaq  SmallCap Market or the Nasdaq
National  Market,  as  applicable,  upon which shares of Common Stock are listed
(subject to official  notice of  issuance)  and shall  maintain,  so long as any
other shares of Common Stock shall be so listed, such listing of all Registrable
Securities  from  time to time  issuable  under  the  terms  of the  Transaction
Documents.  The Company  shall  maintain the Common  Stock's  authorization  for

applicable. The Company shall promptly provide to Angelo, Gordon & Co., as agent
for the  Buyers,  copies of any  notices it  receives  from the Nasdaq  SmallCap
Market or the Nasdaq  National  Market,  as applicable,  regarding the continued
eligibility of the Common Stock for listing on such automated  quotation  system
or  securities  exchange.  The  Company  shall  pay all  fees  and  expenses  in
connection with satisfying its obligations under this Section 4(h).

            i. Expenses. Subject to Section 9(l), following the Initial Closing,
the Company shall reimburse the Buyers for the Buyers' reasonable attorneys fees
and expenses in  connection  with  negotiating  and  preparing  the  Transaction
Documents and  consummating  the  transactions  contemplated  thereby,  up to an
aggregate of $20,000.

            j.  Filing  of Form 8-K.  On or  before  the  fifteenth  (15th)  day
following each of the Closing Dates,  the Company shall file a Form 8-K with the
SEC  describing the terms of the  transaction  contemplated  by the  Transaction
Documents and consummated at such Closing,  in each case in the form required by
the 1934 Act.

            k.    Sale Restrictions.

            (i)  Prior  to  conversion  of any or all of the  Debentures  or the
exercise of any or all of the Warrants, without the prior written consent of the
Company, no Buyer shall enter into any short position involving the Common Stock
in an amount such that the aggregate  short  position of all Buyers  exceeds the
greatest of (i) 20% of the average daily  trading  volume of the Common Stock on
the Nasdaq SmallCap Market or the Nasdaq National Market, as applicable, for the
five  trading  days  immediately  preceding  the date of  sale,  (ii) 20% of the
trading volume of the Common Stock on the Nasdaq  SmallCap  Market or the Nasdaq
National Market, as applicable,  on the day prior to the date of sale; and (iii)
50,000 shares.

            (ii) Following the conversion of any or all of the Debentures or the
exercise of any or all of the Warrants, without the prior written consent of the
Company,  no Buyer will sell at any time any Conversion Shares or Warrant Shares
in an amount such that the total number of Conversion  Shares and Warrant Shares
sold by all Buyers  exceeds the greatest of (i) 10% of the average daily trading
volume of the Common Stock on the Nasdaq  SmallCap Market or the Nasdaq National
Market, as applicable,  for the five trading days immediately preceding the date
of sale;  (ii) 10% of the  trading  volume  of the  Common  Stock on the  Nasdaq
SmallCap Market or the Nasdaq National Market,  as applicable,  on the day prior
to the date of sale; and (iii) 35,000 shares.

            l. Underwriting  Lock-Up  Agreements.  At any time during the period
beginning on and including the Initial Closing Date and ending on the date which
is eighteen  months after the Initial Closing Date, the Company may require that
all,  but not less than all, of the holders of the  Debentures  and the Warrants


                                   - 19 -




<PAGE>


Exhibit 4.1

agree to sign a "lock-up"  agreement with the  underwriters of a public offering
of the Common Stock  pursuant to which the holders would agree that,  during the
period beginning on the date designated by the Company,  which date shall be not
less than ten (10) days after the holders' receipt of such notice, and ending on
the date which is the earlier of the  closing  date of such  offering  and sixty
(60) days after the beginning of the lock-up period as designated by the Company
(the "Underwriting Lock-Up Period"),  such holders would not sell any Conversion
Shares issued to the holders  pursuant to a Conversion  Notice  delivered to the
Company or any Warrant Shares issued to the holders . The Company shall exercise
this right by delivering  written notice (the "Lock-Up  Request Notice") of such
request to all of the holders of the Debentures and Warrants then outstanding at
least 10 days prior to the date on which the  Underwriting  Lock-Up  Period will
begin,  but in no event prior to the filing of the  registration  statement  for
such  proposed  offering.  The Lock-up  Request  Notice shall state (i) that the
underwriters  of such offering have requested that the holders of the Debentures
and the Warrants  enter into  "lock-up"  agreements,  (ii) the date on which the
Underwriting  Lock-Up  Period  will  begin and  (iii)  the name of the  managing
underwriters  of the  proposed  offering.  Notwithstanding  the  foregoing,  the
Company  shall not be  entitled  to require  the  holders to enter into  lock-up
agreements unless (A) the Underwriting  Lock-Up Period is not more than 60 days,
(B) the  Underwriting  Lock-Up  Period  shall  terminate  immediately  upon  the
termination or abandonment or indefinite delay of the underwritten offering, (C)
the  managing  underwriters  for such  proposed  offering  are  included  on the
Schedule  of  Underwriters  attached  to this  Agreement,  (D)  the  preliminary
prospectus for such  underwritten  public offering reflects a price per share to
the public of not less than $10.00 per share and an aggregate  gross proceeds to
the Company of at least  $20,000,000,  (E) there has been no other  Underwriting
Lock-Up Period in the 365 days prior to the date of the Lock-Up  Request Notice,
and (F) there has been no Grace  Period (as defined in the  Registration  Rights
Agreement)  during the period  beginning on and  including the date which is ten
days prior to the filing of the registration statement for the proposed offering
and ending on and including the first day of the Underwriting Lock-Up Period. If
the  Company  delivers  a Lock-Up  Request  Notice and the  underwritten  public
offering is not consummated  within 90 days of the first day of the Underwriting
Lock-Up  Period and such failure to consummate the offering is due to any action
of the Company or any  failure of the  Company to act,  then the Company may not
require any  additional  Underwriting  Lock-Up  Period  pursuant to this Section
4(l).

      5.    TRANSFER AGENT INSTRUCTIONS.
            ----------------------------

            The Company  shall issue  irrevocable  instructions  to its transfer
agent, and any subsequent transfer agent, to issue  certificates,  registered in
the name of each  Buyer or its  respective  nominee(s),  for (i) the  Conversion
Shares in such  amounts  as  specified  from  time to time by each  Buyer to the
Company upon  conversion  of the  Debentures  in  accordance  with the terms and
conditions  of the  Transaction  Documents  and (ii) the Warrant  Shares in such
amounts  as  specified  from  time to time by each  Buyer  to the  Company  upon
exercise of the  Warrants in  accordance  with the terms and  conditions  of the
Transaction Documents (the "Irrevocable Transfer Agent Instructions").  Prior to


                                   - 20 -




<PAGE>


Exhibit 4.1

registration of the Conversion Shares and the Warrant Shares under the 1933 Act,
all such  certificates  shall bear the restrictive  legend  specified in Section
2(g).  The  Company  warrants  that,  except  as set  forth  in the  Transaction
Documents, no instruction other than the Irrevocable Transfer Agent Instructions
referred to in this Section 5, and stop transfer  instructions to give effect to
Section 2(f) (prior to registration of the Conversion  Shares and Warrant Shares
under the 1933 Act), will be given by the Company to its transfer agent and that
the Securities  shall otherwise be freely  transferable on the books and records
of the  Company  as and to  the  extent  provided  in  this  Agreement  and  the
Registration Rights Agreement. Nothing in this Section 5 shall affect in any way
each Buyer's obligations and agreements set forth in Section 2(g) to comply with
all  applicable  prospectus  delivery  requirements,  if any, upon resale of the
Conversion Shares or the Warrant Shares. If a Buyer provides the Company with an
opinion  of  counsel,  reasonably  satisfactory  in form  and  substance  to the
Company,  that  registration of a resale by such Buyer of any of such Securities
is not required  under the 1933 Act, the Company shall permit the transfer,  and
promptly  instruct its transfer agent to issue one or more  certificates in such
name and in such  denominations  as  specified  by such  Buyer and  without  any
restrictive  legends.  The  Company  acknowledges  that  a  breach  by it of its
obligations  arising  under this  Section 5 will cause  irreparable  harm to the
Buyers by  vitiating  the intent and  purpose  of the  transaction  contemplated
hereby.  Accordingly,  the  Company  acknowledges  that the  remedy at law for a
breach of its obligations under this Section 5 will be inadequate and agrees, in
the event of a breach or threatened  breach by the Company of the  provisions of
this  Section 5, that the Buyers  shall be  entitled,  in  addition to all other
available  remedies,  to an  injunction  restraining  any breach  and  requiring
immediate issuance and transfer,  without the necessity of showing economic loss
and without any bond or other security being required.

      6. CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.
         -----------------------------------------------

            a. Initial Closing Date. The obligation of the Company  hereunder to
issue and sell the Initial  Debentures and Initial Warrants to each Buyer at the
Initial Closing is subject to the satisfaction, at or before the Initial Closing

      amendments required for the consummation of the transactions  contemplated

Closing  is  subject  to the  Company's  delivery  of the  Put  Notice  and  the
satisfaction,  at or  before  the Put  Closing  Date,  of each of the  following
conditions,  provided that these  conditions  are for the Company's sole benefit
and may be waived by the Company at any time in its sole discretion by providing
each Buyer with written notice thereof:

      Price for the Put  Debentures  and Put  Warrants  being  purchased by such
      Buyer at the Put Closing by wire transfer of immediately  available  funds

      (except for  representations  and  warranties  that speak as of a specific
      date), and such Buyer shall have performed,  satisfied and complied in all
      material respects with the covenants,  agreements and conditions  required
      by the Transaction  Documents to be performed,  satisfied or complied with
      by such Buyer at or prior to the Put Closing Date.

            (iii) No suit,  action or other proceeding shall have been commenced
      (and be pending)  which seeks to  restrain  or prohibit or  questions  the
      validity or legality of the  transactions  contemplated by the Transaction
      Documents, nor shall any such suit, action or proceeding be threatened.

including  reasonable  attorneys' fees and disbursements (the "Buyer Indemnified
Liabilities"),  incurred by any Buyer  Indemnitee as a result of, or arising out

      outstanding are not altered by such  reorganization  or  readjustment)  on
      account  of the  indebtedness  evidenced  by the  Debentures  to which the
      holders of the Debentures  would be entitled  except for the provisions of
      this Paragraph 1, shall be paid or delivered by the trustee in bankruptcy,

      making  such  payment or  distribution  directly  to the holders of Senior

      or  trustees  under  any  indenture  pursuant  to  which  any  instruments
      evidencing any of such Senior Indebtedness may have been issued, pro rata,
      as their respective interests may appear for application to the payment of
      all Senior  Indebtedness  remaining  unpaid to the extent necessary to pay

of the  Debentures,  for the purpose of  ascertaining  the  persons  entitled to

        (d) In the event that any direct or indirect  payment or distribution of
assets of the  Company of any kind or  character,  whether in cash,  property or

securities  of the Company or any other  corporation  provided  for by a plan of
reorganization or readjustment the payment of which is subordinate,  at least to
the extent provided in this Paragraph 1 with respect to the  Debentures,  to the
payment of all indebtedness of the nature of Senior Indebtedness,  provided that
the rights of the holders of Senior Indebtedness at the time outstanding are not

Debentures  shall  be  subrogated  to  the  rights  of  the  holders  of  Senior
Indebtedness to receive  payments or distributions of assets of the Company made
on the Senior  Indebtedness  until the  Debentures and interest shall be paid in
full, and for purposes of such subrogation, no such payments or distributions to
the  holders of Senior  Indebtedness  of cash,  property  or  securities,  which
otherwise  would be payable or  distributable  to the holders of the Debentures,
shall,  as between the Company,  its creditors  other than the holders of Senior
Indebtedness,  and the holders of the  Debentures,  be deemed to be a payment by
the Company to or on account of Senior  Indebtedness,  it being  understood that
the provisions of this  Paragraph 1 are and are intended  solely for the purpose
of defining the  relative  rights of the holders of the  Debentures,  on the one
hand, and the holders of Senior Indebtedness, on the other hand.

or in the  Purchase  Agreement  is intended to or shall  impair,  as between the
Company,  its creditors  other than the holders of Senior  Indebtedness  and the
holders of the Debentures,  the obligation of the Company, which is absolute and
unconditional,  to pay to the holders of the  Debentures  the  principal  of the
Debentures,  premium,  if any, and interest thereon,  as and when the same shall
become due and payable in accordance with their terms, or to affect the relative
rights of the holders of the  Debentures and creditors of the Company other than
the holders of Senior Indebtedness, nor shall anything herein or therein prevent
the holder of any Debentures from exercising all remedies otherwise permitted by
applicable law upon default under this Debenture, subject to the rights, if any,
under this Paragraph 1 of the holders of Senior Indebtedness in respect of cash,
property or  securities  of the Company  received  upon the exercise of any such
remedy.

        (g) No direct or indirect  payment (in cash,  property,  securities,  by
set-off  or  otherwise)  shall be made or  agreed to be made on  account  of the
principal of the Debentures, premium, if any, or interest thereon, or in respect
of any  redemption,  retirement,  purchase  or other  acquisition  of any of the
Debentures,  and no  holder of any  Debentures  shall be  entitled  to demand or
receive  any such  payment  (i)  unless all  amounts  then due and  payable  for
principal of (premium,  if any) and  interest on all Senior  Indebtedness  shall
have been paid in full or (ii) if at the time of such  payment  or after  giving
effect  thereto there shall have occurred and be continuing any event of default
under any Senior  Indebtedness  or under any agreement or indenture  pursuant to
which any  instruments  evidencing  any such Senior  Indebtedness  may have been
issued and the maturity of such Senior  Indebtedness shall have been accelerated
as a result of such default.

        Notwithstanding the foregoing,  the Company may make payments on account
of the  principal  of,  premium,  if any, or interest on the  Debentures,  or in
respect of any redemption,  retirement,  purchase or other acquisition of any of
the  Debentures  when (a) the Company  has  received a notice of a default or an
event of default under any agreement  governing Senior  Indebtedness (other than
notice of a default or event of default  relating  to  payment of  principal  or
interest,  either at maturity,  upon  redemption,  by acceleration or otherwise)
(the receipt of such notice being referred to herein as a "Blockage Event"), and
(b) 179 days pass after the  earliest  date on which such  notice was given with
respect to such default or event of default (the "Payment Blockage Period"),  so
long as this  Paragraph  1  otherwise  permits  payment at that time;  provided,
however,  that only one  Payment  Blockage  Period may be  commenced  within any
consecutive 365-day period with respect to the Debentures.  For purposes of this
paragraph,  no event of default which  existed or was  continuing on the date of
the  commencement  of any Payment  Blockage  Period  with  respect to the Senior
Indebtedness  initiating such Payment  Blockage Period shall be, or be made, the
basis  for  the   commencement  of  a  second  Payment   Blockage  Period  by  a
representative  of  such  Senior  Indebtedness,  whether  or not within a period

      1 to 45 days after Closing Date                         0%
      46 to 90 days after Closing Date                       25%

The foregoing  conversion  restrictions  shall  immediately  terminate,  and the
Holder shall be permitted to convert all or any part of this  Debenture  without
regard  to the  conversion  restrictions,  upon the  occurrence  of any Event of
Default,  Paragraph 4 Transaction or upon the  commencement by any person (other
than the Holder) of any tender offer for shares of Common Stock.

                  (ii) Company's Right to Force Conversion.  (A) The Company may
require  conversion  of all or  any  part  of the  Outstanding  Amount  of  this
Debenture from time to time into fully paid,  validly  issued and  nonassessable
shares of Common Stock; provided, that

                        (1)  prior  to the date on which the Company may require
such  conversion,  the Registration  Statement  contemplated by the Registration
Rights Agreement shall have been declared effective (and not subject to any stop

permit the sale thereunder of not less than the Minimum Number of Shares;

                        (2)  the Registration Statement shall be effective  (and
not subject to any stop  orders or other  prohibitions  on sale of Common  Stock
thereunder)  as of the date of delivery of the Forced  Conversion  Notice and on
each trading day commencing  with the date of delivery of the Forced  Conversion
Notice and ending on the Forced  Conversion  Date for the sale thereunder of not
less than the Minimum Number of Shares;

                        (3)  the average closing price per share of Common Stock
for the five  trading  days  immediately  preceding  the  delivery of the Forced
Conversion Notice shall have been greater than or equal to 130% of the Ceiling;

                        (4)  (A) no  Event  of  Default  as specified in Section
17(c),  (d),  (e),  (f),  (g) or (h) shall  have  occurred  prior to the  Forced
Conversion Date and (B) no Event of Default as specified in Section 17(a) or (b)
shall have occurred and be continuing as of the Forced Conversion Date;

                        (5)  no Conversion Deficiency  shall have occurred prior
to the Forced Conversion Date; and

                        (6)  any  such  required  conversion  shall be made from
each Holder,  pro rata according to the portion of the total Outstanding  Amount
of all Debentures held by each Holder.

            (B) Notwithstanding clause (A) of this Paragraph 5(a)(ii), after the
second  anniversary of the Closing Date,  the Company may require  conversion of
all or any part of this  Debenture  from time to time into fully  paid,  validly
issued and nonassessable shares of Common Stock; provided, that

                        (1)  (A) no  Event  of  Default  as specified in Section

Exhibit 4.2


                        (2)  no  Conversion Deficiency shall have occurred prior
to the Forced Conversion Date; and

                        (3)  any  such  required  conversion  shall be made from
each Holder,  pro rata according to the portion of the total Outstanding  Amount
of all Debentures held by each Holder.

                  (iii)  Automatic   Conversion.   At  the  Maturity  Date,  the
Outstanding  Amount of this  Debenture  plus any unpaid charges or amounts shall
automatically  be converted into fully paid,  validly  issued and  nonassessable
shares of Common Stock and,  except for the Holder's right to receive the Common
Stock into which this Debenture is  automatically  so converted,  and except for
any  portion  of  this  Debenture  which  cannot  be  converted  because  of the
limitations  contained in  Paragraphs  5(d) and 9(b),  this  Debenture  shall be
deemed to have been  canceled  whether or not  surrendered  upon such  automatic
conversion.

                  (iv) Accrued But Unpaid Interest.  Notwithstanding anything in
this Debenture to the contrary,  the Outstanding Amount of this Debenture on any
Holder  Conversion Date or any Forced Conversion Date, as the case may be, shall
include,  without  limitation,  all  accrued  but  unpaid  interest  under  this
Debenture through such date.

            (b) Conversion  Price for Holder Converted  Shares.  The Outstanding
Amount of this Debenture shall be convertible into the number of validly issued,
fully paid and  non-assessable  shares of Common Stock  determined in accordance
with the following formula:

                                     P + I
                          -------------------------
                         Conversion Date Market Price

         P =    principal amount of this Debenture submitted for conversion

         I =    accrued  but  unpaid  interest on the  principal  amount of this
                Debenture  submitted for  conversion  plus any unpaid charges or
                amounts through the Holder  Conversion Date or Forced Conversion
                Date, as the case may be.

      The number of shares of Common Stock into which the Outstanding  Amount of
this Debenture may be converted pursuant to this paragraph is herein referred to
as the "Conversion Rate."

                  (c) (i) Mechanics of Conversion by Holder. In order to convert
this  Debenture  (in whole or in part) into shares of Common  Stock,  the Holder
shall surrender this Debenture,  duly endorsed,  by either overnight  courier or
two-day  courier,  to the Company,  and, in case of any  conversion  pursuant to


                                   - 10 -




<PAGE>


Exhibit 4.2

Paragraph  5(a)(i),  shall give  written  notice in the form of Exhibit A hereto
(the  "Conversion  Notice")  by  facsimile  (with the  original  of such  notice
forwarded  with the foregoing  courier) to the Company that the Holder elects to
convert all or the portion of the Outstanding Amount of this Debenture specified
therein, which notice and election shall be irrevocable by the Holder unless the
Company  shall  default  in or fail  to  fulfill  any or all of its  obligations
arising  hereunder or  otherwise by reason of such notice or election,  in which
case, in addition to and not in lieu of any and all other rights and remedies to
which the Holder may thereby be and become  entitled,  such notice and election,
by further notice to the Company may be revoked and rescinded at the election of
the Holder exercised in its sole discretion; provided, however, that the Company
shall not be obligated  to issue  certificates  evidencing  the shares of Common
Stock  issuable  upon  conversion  unless this  Debenture  with  evidence of the
principal  amount hereof to be converted is delivered to the Company as provided
above,  or the Holder  notifies the Company that this  Debenture  has been lost,
stolen or destroyed and promptly executes an agreement  reasonably  satisfactory
to the Company to  indemnify  the Company from any loss which may be incurred by
it  in  connection  with  this  Debenture;  and  provided,  further,  that  each
Conversion  Notice shall provide for the Holder's election to convert either (A)
at least $250,000 of the Outstanding  Amount of this  Debenture,  or (B) if such
Outstanding  Amount  shall then be less than  $250,000,  the entire  Outstanding
Amount.  The date on which a Conversion Notice is given (the "Holder  Conversion
Date")  shall be deemed to be the date the  Company  received by  facsimile  the
Conversion Notice, as evidenced by a printed confirmation of receipt received by
the Holder and  confirmed  by  telephone  conference  between the Holder and the
Company.  Upon receipt of any Conversion  Notice,  the Company shall immediately
verify the  Holder's  calculation  of the  Conversion  Rate.  Unless the Company
objects, in writing,  to the Holder's  calculation within four (4) business days
after the Holder  Conversion  Date,  the Company will be deemed to have accepted
such calculation.

                (ii)  Mechanics  of Forced  Conversion  by Company.  In order to
require conversion of this Debenture pursuant to Paragraph 5(a)(ii), the Company
shall  give  written  notice  in the form of  Exhibit  B  hereto,  appropriately
completed (the "Forced Conversion  Notice"),  by facsimile (with the original of
such notice forwarded with the foregoing  courier) to each Holder of Debentures.
Such Forced  Conversion  Notice  shall  state that the  Company  elects to force
conversion  of all or a  specified  portion  of the  Outstanding  Amount  of the
Debentures of each Holder, which notice and election shall be irrevocable by the
Company  and shall be  delivered  at least 10 trading  days prior to the date of
conversion  specified in the Forced  Conversion  Notice (the "Forced  Conversion
Date").  Each Holder will,  within two business days after the Forced Conversion
Date, to the extent the Debenture has not been converted by such Holder prior to
the Forced  Conversion Date,  deliver such Debenture  evidencing the Outstanding
Amount of such  Debenture  to be converted to the  Company,  duly  endorsed,  by
either  overnight  courier or two-day  courier,  or notify the Company that such
Debenture has been lost,  stolen or destroyed and promptly  execute an agreement
reasonably  satisfactory  to the Company to indemnify  the Company from any loss


                                   - 11 -




<PAGE>


Exhibit 4.2

which may be incurred by it in connection with such  Debenture.  Notwithstanding
anything  herein to the  contrary,  any Holder may  convert  any  portion of its
Debentures prior to the Forced Conversion Date.

               (iii)  Issuance of  Certificates.  In the case of any  Conversion
Notice given by the Holder or any Forced Conversion Notice given by the Company,
the Company shall use its best efforts to cause the Company's transfer agent for
the Common Stock to issue and deliver as promptly as practicable and in no event
later than two (2) business days after delivery to the Company of the Debenture,
or after receipt of such agreement and indemnification, to such Holder or to its
designee, a certificate or certificates for the number of shares of Common Stock
to which  the  Holder  shall be  entitled,  together  with a  Debenture  for the
principal amount not submitted for conversion or forced to convert,  as the case
may be. The person or persons  entitled  to receive  the shares of Common  Stock
issuable upon conversion  shall be treated for all purposes as the record holder
or holders of such shares of Common Stock on the Holder  Conversion  Date or the
Forced  Conversion  Date,  as the case may be. If the Company shall not have the
requisite  number of shares of Common  Stock  issuable  upon  conversion  of the
Debentures by any Holder,  then,  without  limiting the Company's  obligation to
convert all of the Debentures,  such  conversion  shall be made for each Holder,
pro rata according to the portion of the total Outstanding Amount of the portion
of the Debentures  sought to be converted.  At the Holder's option,  the request
for conversion by the Holder or the required  conversion by the Company shall be
null and void for any portion of the  Debentures  for which the Company does not
have shares of Common Stock issuable upon conversion as of the Holder Conversion
Date or the Forced Conversion Date.

      6.  Redemption.
          -----------

            (a)   Company Option To Redeem.  Any  portion  of this Debenture may
be redeemed at the Company's option expressed by a written notice (a "Redemption
Notice") to the Holder; provided that

                  (i) the  closing  price per share of Common  Stock for each of
the ten (10) consecutive trading days immediately  preceding the delivery of the
Redemption  Notice  shall have been less than $6.50 per share,  such price to be
proportionately  adjusted in the event of a subdivision,  split-up,  spin-off or
combination in accordance with Section 7(a);

                  (ii) the Redemption  Notice  delivered by the Company shall be
received by the Holder at least ten (10)  trading  days (but not more than forty
(40) trading days) prior to the date (the "Redemption Date") of redemption;

                (iii) at all  times  from and after  the  effective  date of the
Registration  Statement  contemplated by the Registration Rights Agreement,  the


                                   - 12 -




<PAGE>


Exhibit 4.2

Registration  Statement  shall have been effective for sale  thereunder  (except
pursuant  to  suspension  periods   contemplated  by  the  Registration   Rights
Agreement) of not less than the Minimum Number of Shares;

               (iv)  the  Registration  Statement  shall be  effective  (and not
subject  to any  stop  orders  or other  prohibitions  on sale of  Common  Stock
thereunder)  on the date of  delivery of the  Redemption  Notice and on each day
from  the  date of such  delivery  through  the  Redemption  Date  for the  sale
thereunder of not less than the Minimum Number of Shares;

                (v) on the date of the Redemption Notice, the Company shall have
deposited at least seventy  percent (70%) of the  Redemption  Price in an escrow
account  reasonably  satisfactory  to the Holder,  and shall have  notified  the
Holder in writing  that the Company  shall have  adequate  liquidity  to pay the
Redemption  Price on the Redemption  Date, and shall not be prohibited under the
terms of any financing or other  agreements or applicable law from redeeming the
Debentures on the Redemption Date; and

                  (vi) no Conversion  Deficiency,  as defined in Paragraph 9(b),
shall have occurred prior to the Redemption Date.

            (b) Company's  Obligation  To Redeem.  Upon a  determination  by the
Holders of more than 50% of the principal amount of Debentures then outstanding,
the Holders of the  Debentures  shall have the right to demand from the Company,
upon written  notice to the Company at any time after the  occurrence  of any of
the following  events,  redemption of all  Debentures in cash at the  Redemption
Price pursuant to this Paragraph 6 in the event of the following:

                  (i) the  Registration  Statement  shall not have been declared
effective within 180 days after the Closing Date; or

                  (ii) the failure of the  Company to comply  with a  Conversion
Notice, other than pursuant to Paragraph 9(b) hereof.

            (c) Redemption  Price.  The redemption price for the portion of this
Debenture  being  redeemed,  except  as  provided  in  the  Registration  Rights
Agreement,  shall  equal  110%  of the  outstanding  principal  amount  of  this
Debenture  being so redeemed,  plus all accrued but unpaid interest and all late
payment  charges and all other  amounts  accrued  under this  Debenture  and not
previously paid (the "Redemption  Price"). The Redemption Price shall be payable
in cash in United States Dollars.

            (d)  Mechanics of  Redemption.  If less than all of the  Outstanding
Amount of Debentures are to be redeemed at any time, selection of Debentures for
redemption  will be made by the  Company on a pro rata  basis.  In the event the


                                   - 13 -




<PAGE>


Exhibit 4.2

Company shall be required or elects to redeem any part or all of the Outstanding
Amount of the Debentures,  the Company shall send by either overnight courier or
two-day   courier  (with  a  copy  sent  by  facsimile)   confirmation  of  such
determination  or  obligation  to the  record  Holders of the  Debentures  being
redeemed (the "Redemption Debentures"),  which confirmation shall be included in
the  Redemption  Notice,  if the  redemption is made pursuant to Paragraph  6(a)
above. Such  confirmation  shall specify the Redemption Date, which shall be (i)
no later than seven (7)  business  days after the  receipt by the Company of the
notice requiring  redemption  pursuant to Paragraph 6(b) above, or (ii) at least
20 trading days (but not more than 40 trading  days) after receipt by the Holder
of the Redemption Notice, as applicable.  On the Redemption Date, the Redemption
Debentures  shall be redeemed  automatically  without any further  action by the
Holders of such  Debentures and whether or not the Debentures are surrendered to
the  Company  (but  only to the  extent  that  the  Company  complies  with  its
obligation to pay the Redemption  Price  therefor);  provided,  that the Company
shall  be  obligated  to pay the  cash  consideration  due to a  Holder  of such
Debentures  upon  redemption  when such  Debentures are either  delivered to the
principal  office of the Company or the Holder  notifies  the Company  that such
Debentures  have been  lost,  stolen or  destroyed  and  executes  an  agreement
reasonably  satisfactory  to the Company to indemnify  the Company from any loss
which may be incurred by it in connection with such Debenture.  Thereupon, there
shall be promptly issued and delivered to such Holder, within seven (7) business
days after the Redemption  Date and delivery to the Company of such  Debentures,
or after receipt of such agreement and  indemnification,  at the address of such
Holder on the books of the Company,  payment in immediately  available  funds to
the name as shown on the books of the  Company in the  amount of the  Redemption
Price as  calculated  as set forth in Paragraph  6(c).  If the Company shall not
have the funds available to pay the aggregate Redemption Price of all Redemption
Debentures,  then,  without  limiting  the  Company's  obligation  to redeem all
Redemption Debentures,  such redemption shall be made from each Holder, pro rata
according  to the  portion  of the total  Outstanding  Amount of all  Redemption
Debentures  then held by each Holder and the Company  shall not be  permitted to
require any further redemption in accordance with Paragraph 6(a).

      Notwithstanding  anything to the contrary  contained herein,  the Holders'
rights of conversion  pursuant to Paragraph 5 hereof shall not be limited in any
manner by the Company's rights of redemption pursuant to this Paragraph 6.

            (e) Failure to Redeem. In the event that the Company fails to redeem
any portion of the Outstanding Amount of the Debentures  required to be redeemed
on any  Redemption  Date, the Company shall pay, in cash, to each Holder on such
Redemption Date, and on the last day of each 30-day period  thereafter until the
Company redeems such unredeemed  portion, an amount equal to two percent (2%) of
the  unredeemed  portion of the  Outstanding  Amount of the  Debentures  of such
Holder.  This amount shall be deemed to be  liquidated  damages and shall not be
credited against the Redemption Price.

Exhibit 4.2

      7.    Stock Splits, Dividends, Reorganizations.
            ------------- ---------- ----------------

            (a) Adjustment for Subdivisions,  Combinations,  etc. If the Company
shall  subdivide  its  outstanding  Common  Stock,  by  split-up,  spin-off,  or
otherwise,  or combine its outstanding Common Stock, then the Conversion Rate in
effect as of the date of such subdivision,  split-up,  spin-off,  or combination
shall forthwith be proportionately adjusted.

            (b)  Adjustment  for Dividends and  Distributions.  In the event the
Company at any time or from time to time after the Closing Date makes,  or fixes
a record  date for the  determination  of holders of Common  Stock  entitled  to
receive, a dividend or other distribution  payable in Common Stock (or rights to
acquire Common Stock),  then and in each such event  provision  shall be made so
that the Holders of Debentures shall receive upon conversion thereof pursuant to
Paragraph  5 hereof,  in  addition  to the  number  of  shares  of Common  Stock
receivable  thereupon,  the amount of such other  securities  of the  Company to
which a Holder on the relevant  record or payment  date, as  applicable,  of the
number of shares of Common Stock so receivable upon  conversion  would have been
entitled,  plus any  dividends  or other  distributions  which  would  have been
received with respect to such securities, had such Holder thereafter, during the
period from the date of such event to and including the Holder  Conversion  Date
or Forced Conversion Date, as the case may be, retained such securities, subject
to all other  adjustments  called for during such period under this  Paragraph 7
with  respect to the rights of the Holders of the  Debentures.  For  purposes of
this  Paragraph  7(b),  the number of shares of Common Stock so receivable  upon
conversion  shall be  deemed  to be that  number  which the  Holder  would  have
received upon conversion of the entire  Outstanding  Amount hereof if the Holder
Conversion Date or Forced  Conversion Date, as the case may be, had been the day
preceding the date upon which the Company  announced the making of such dividend
or other distribution.

            (c) Adjustment for Merger, Reorganization; etc. In the event that at
any time or from time to time after the Closing Date,  the Common Stock issuable
upon conversion of the Debentures is changed into the same or a different number
of shares of any class or classes of stock,  whether in connection with a merger
or  consolidation,  by  recapitalization,  reclassification,  reorganization  or
otherwise (other than a subdivision,  or combination of shares or stock dividend
or reorganization  provided for elsewhere in this Paragraph 7), then and in each
such  event each  Holder of  Debentures  shall  have the right,  for a period of
fifteen (15) days following  receipt of the Company's notice of such adjustment,
to convert such Debentures into the kind of securities receivable by a holder of
Common  Stock  upon such  merger,  recapitalization,  reclassification  or other
change,  all subject to further  adjustment as provided  herein.  In the event a
Holder does not elect to convert all of its  Debentures  during the  fifteen-day
period described in the preceding sentence,  the Company may, in its discretion,
elect to redeem all unconverted  Debentures of the Holders at a redemption price
equal to 120% of the  Outstanding  Amount of the  Debentures  being so redeemed,


                                   - 15 -




<PAGE>


Exhibit 4.2

plus all late payment charges and all other amounts accrued under the Debentures
and not  previously  paid.  Such  redemption  price  shall be payable in cash in
United States Dollars. The Company shall make such redemption in accordance with
Paragraph 6(d).

            (d)  Certificate  as to  Adjustments.  Upon  each  occurrence  of an
adjustment  pursuant  to this  Paragraph  7, the  Company at its  expense  shall
furnish to each Holder a certificate  setting forth (i) in reasonable detail the
facts  upon  which such  adjustment  is based,  and (ii) the number of shares of
Common Stock and the amount of other  property or  securities  that after giving
effect  thereto  would  be  received  by the  Holder  upon  conversion  of  this
Debenture.

            (e)  Disputes.  In the event of a  reasonable,  good  faith  dispute
between a Holder of Debentures  and the Company with respect to the  adjustments
required  by  Paragraphs  7(a),  (b) or (c),  then,  at the option of either the
Holders  of  Debentures  evidencing  50% or more of the  principal  indebtedness
evidenced  by all  Debentures  held by Holders  involved in such  dispute or the
Company, the dispute shall be submitted to the American Arbitration  Association
for resolution  according to the then applicable rules thereof. The cost of such
proceeding shall be borne by the  non-prevailing  party,  except that each party
shall bear its own legal and other expenses.

      8.  Fractional  Shares.  No  fractional  shares of  Common  Stock or scrip
representing fractional shares of Common Stock shall be issuable hereunder.  The
number of shares of Common Stock that are issuable upon any conversion  shall be
rounded up or down to the nearest whole share.

      9.    Reservation of Stock Issuable Upon Conversion.
            ----------------------------------------------

            (a)  Reservation  Requirement.  The  Company  has  reserved  and the
Company  shall  continue to reserve  and keep  available  at all times,  free of
preemptive  rights,  shares of Common  Stock for the  purpose  of  enabling  the
Company to  satisfy  any  obligation  to issue  shares of its Common  Stock upon
conversion of the Debentures. The number of shares so reserved may be reduced by
the number of shares  actually  delivered  pursuant to  conversion of Debentures
(provided  that in no event  shall the number of shares so reserved be less than
the Minimum  Number of Shares  applicable  to any  Debenture)  and the number of
shares so reserved  shall be increased or  decreased  proportionally  to reflect
stock splits,  stock  dividends and other  distributions.  In the event that the
number of shares so reserved  (either in the  aggregate or as to any  Debenture)
shall be insufficient  for issuance upon  conversion of the Debentures  (without
giving effect to an applicable  conversion  restrictions),  or if the Holders of
the  Debentures  would at any time upon  conversion  thereof be  entitled to the
issuance of shares of Common  Stock in excess of the  limitation  in  Paragraphs
5(d) and 9(b) herein, then in either case, upon receipt by the Company of notice
from any Holder, the Company shall use its best efforts and all due diligence to
increase  the  number  of  shares  so  reserved  (without  giving  effect to any


                                   - 16 -




<PAGE>


Exhibit 4.2

applicable conversion restrictions) to cure all such deficiencies (either in the
aggregate or as to any Debenture)  and, if necessary,  to obtain the approval by
its shareholders therefor, including the authorization of such additional number
of shares of Common  Stock as may be  required to issue such shares in excess of
the number so reserved  (either in the  aggregate or as to any  Debenture) or in
excess of such limitation, as the case may be.

            (b) Conversion Deficiency.  If, upon receipt of a Conversion Notice,
the  Company  does not have a  sufficient  number  of  shares  of  Common  Stock
available  to satisfy  the  Company's  obligations  to issue  Common  Stock upon
conversion  of all or any of the  Debentures  to be so converted (a  "Conversion
Deficiency"),  any Holder of the Debentures  shall have the right to demand from
the Company  immediate  redemption of any portion of the Debentures with respect
to which the Company  does not have a sufficient  number of shares  available to
satisfy such conversion obligations, in cash at the Redemption Price pursuant to
Paragraph 6 hereof,  without  regard to Paragraphs  6(d) or 6(e) hereof.  Within
three business days of the occurrence of any Conversion Deficiency,  the Company
shall notify each Holder in writing of such occurrence.

      Within three business days of the receipt of written demand for redemption
from any Holder  pursuant to this Paragraph  9(b), the Company shall notify each
such Holder whether the Company has adequate liquidity to redeem such portion of
the Debentures as required by the foregoing paragraph (and, if requested by such
Holder,  will provide  reasonable  written support for its position with respect
thereto within ten business days of the occurrence of any Conversion Deficiency)
and whether such  redemption is  prohibited  under the terms of any financing or
other agreements or applicable law.

      In the event that the  Company  notifies  the  Holder in writing  that the
Company has adequate  liquidity and is not otherwise  restricted  from redeeming
such portion of this  Debenture,  then the Company  shall pay, in cash,  to such
Holder within three business days after which a Conversion Deficiency shall have
occurred  and on the last  day of each  30-day  period  for  which a  Conversion
Deficiency is  continuing,  an amount equal to one percent (1%) of the amount of
such portion of the Debentures which such Holder does not require the Company to
redeem, for a maximum of three percent (3%) for such Conversion Deficiency.

      In the event that the Company  does not notify the Holder in writing  that
the Company has adequate  liquidity to redeem such portion of the  Debentures or
that the Company is not otherwise restricted from redeeming such portion of this
Debenture,  the Company shall pay, in cash, to such Holder within three business
days after which a Conversion Deficiency shall have occurred and on the last day
of each 30-day period for which a Conversion  Deficiency is continuing (or until
the Company  establishes to the reasonable  satisfaction  of the Holder that the
Company has adequate liquidity to and is not otherwise prohibited from redeeming
such  Holder's  Debentures,  in  which  case  the  provisions  of the  foregoing

paragraph  shall govern),  two percent (2%) of the amount of such portion of the
Debentures which such Holder does not require the Company to redeem.

      10. Other Covenants of the Company.
          -------------------------------

            (a) The Company shall not intentionally  take any action which would
be  reasonably  likely to impair the  contractual  rights and  privileges of the
Debentures set forth herein or of the Holders thereof.

            (b) The  Company  shall not  incur,  create,  assume,  guarantee  or
otherwise  become liable for any  indebtedness  that is subordinate or junior in
right of payment to any Senior  Indebtedness  of the  Company  and senior in any
respect in right of payment to the Debentures.

            (c) The Company  shall not redeem  (other than pursuant to Paragraph
6), retire,  purchase or otherwise acquire,  directly or indirectly,  Debentures
held by any holder  unless the  Company  shall have  offered to redeem,  retire,
purchase or otherwise  acquire,  as the case may be, the same  proportion of the
aggregate principal amount of Debentures held by each other holder of Debentures
at the time  outstanding upon the same terms and conditions and such offer shall
remain open for a period of at least twenty (20) business days.

      11.  Holders'  Rights if Shares are Delisted or if Trading in Common Stock
is Suspended. In the event that at any time on or after the date hereof, trading
in the shares of the Company's  Common Stock is suspended on the Nasdaq SmallCap
Market or the  Nasdaq  National  Market,  as  applicable,  for a period of seven
consecutive trading days, other than as a result of the suspension of trading in
securities  in general,  or if such Shares are delisted and not relisted  within
twenty (20) trading days  thereafter,  then, at a Holder's  option,  the Company
shall redeem such Holder's  Debentures on a Redemption  Date  designated by such
Holder, and at the Redemption Price and in accordance with Paragraph 6 hereof.

      12.  Limitations  on  Holder's  Obligation  to  Convert.   Notwithstanding
anything  to the  contrary  contained  herein,  no Holder  shall be  required to
convert any part of this  Debenture  in excess of the portion  then  convertible
into  that  number  of  shares  of  Common  Stock   specified  in  the  Holder's
representation  to the Company  that,  after giving  effect to the shares of the
Common Stock to be issued pursuant to such Conversion  Notice,  the total number
of shares of Common Stock deemed beneficially owned by the Holder, together with
all  shares  of the  Common  Stock  deemed  beneficially  owned by the  Holder's
affiliates"  as defined in Rule 144 of the Act,  would  exceed 4.9% of the total
issued and outstanding shares of the Common Stock.

      13.  Obligations  Absolute.  No  provision of this  Debenture,  other than
conversion  as  provided  herein,  shall alter or impair the  obligation  of the


                                   - 18 -




<PAGE>


Exhibit 4.2

Company,  which is absolute  and  unconditional,  to pay the  principal  of, and
interest  on, this  Debenture  at the time,  place and rate,  and in the manner,
herein prescribed.

      14. Waivers of Demand, Etc. The Company hereby expressly waives demand and
presentment  for  payment,  notice of  nonpayment,  protest,  notice of protest,
notice of dishonor, notice of intent to accelerate,  prior notice of bringing of
suit and diligence in taking any action to collect  amounts called for hereunder
and will be directly and primarily liable for the payments of all sums owing and
to be owing hereon,  regardless of and without any notice (except as required by
law),  diligence,  act or omission as or with respect to the  collection  of any
amount called for hereunder.

      15.  Replacement  Debentures.  In the event that the Holder  notifies  the
Company that its  Debenture has been lost,  stolen or  destroyed,  a replacement
Debenture  identical  in all  respects  to the  original  Debenture  (except for
registration  number and Outstanding Amount, if different than that shown on the
original  Debenture)  shall be issued to the  Holder,  provided  that the Holder
executes and delivers to the Company an agreement reasonably satisfactory to the
Company to indemnify the Company from any loss incurred by it in connection with
the  Debenture and provided that the Company is provided a form of Debenture for
such replacement purposes.

      16.  Limitation  on Number of  Conversion  Shares.  In the event that upon
conversion  of the  Debentures  the  Company  would  be  obligated  to  issue an
aggregate amount of shares of Common Stock which exceeds 19.99% of the number of
shares of Common  Stock  outstanding  on the  Closing  Date  (such  amount to be
proportionately  and equitably  adjusted from time to time in the event of stock
dividends,    subdivisions,     combinations,     reclassifications,     capital
reorganizations  and similar events relating to the Common Stock) (the "Exchange
Cap") and such issuance would  constitute a breach of the Company's  obligations
under the rules or  regulations  of the  Nasdaq  SmallCap  Market or the  Nasdaq
National Market, as applicable,  or any other principal  securities  exchange or
market upon which the Common Stock is or becomes  traded,  the Company may elect
to  redeem  in  accordance  with  Paragraph  6 only  that  principal  amount  of
Debentures  which,  if converted,  would result in the issuance of more than the
Exchange Cap. The Exchange Cap shall be allocated  among the Debentures pro rata
based on the total principal amount of Debentures then outstanding.

      17. Defaults.  If one or more of the following events  hereinafter  called
"Events of Default") shall occur:

            (a)   Any of the  representations  or warranties made by the Company
                  herein, in the Purchase Agreement,  in the Registration Rights
                  Agreement,  in  any  other  Transaction  Document,  or in  any
                  certificate or financial  statements of the Company  furnished

then, or at any time thereafter prior to the date on which all continuing Events
of Default have been cured,  and in each and every such case,  unless such Event
of Default  shall have been waived in writing by the Holder  (which waiver shall
not be deemed to be a waiver of any  subsequent  default)  at the  option of the
Holder and in the  Holder's  sole  discretion,  the Holder may, by notice to the
Company declare this Debenture  immediately due and payable,  and the Holder may
immediately,  and without expiration of any period of grace, enforce any and all

Paragraph 6(c).

      18. Savings  Clause.  In case any provision of this Debenture is held by a
court of competent jurisdiction to be excessive in scope or otherwise invalid or
unenforceable, such provision shall be adjusted rather than voided, if possible,
so that it is enforceable to the maximum extent  possible,  and the validity and
enforceability of the remaining provisions of this Debenture will not in any way
be affected or impaired thereby.

      19. Entire  Agreement.  This Debenture and the  agreements  referred to in
this  Debenture  constitute  the full and  entire  understanding  and  agreement
between the Company and the Holder with respect to the subject  hereof.  Neither

Purchase  Agreement,  without  notice,  transfer or assign this Debenture or any
interest  herein  (but  in no  event  in  an  amount  less  than  $1,000,000  in

transfer is exempt from the registration  requirements under the Securities Act.
Each such  assignee or transferee  shall have all of the rights and  obligations
of, the  Holder  under this  Debenture.  The  Company  agrees  that,  subject to
compliance with the Purchase Agreement,  after receipt by the Company of written
notice  of  assignment  from the  Holder  or from  the  Holders'  assignee,  all
principal,  interest, and other amounts which are then due and thereafter become
due under this Debenture  shall be paid to such assignee at the place of payment
designated in such notice.  This Debenture shall be binding upon the Company and
its  successors  and shall inure to the benefit of the Holder and its successors
and assigns.

      21. No Waiver.  No failure on the part of the Holder to  exercise,  and no
delay in exercising,  any right,  remedy or power  hereunder  shall operate as a
waiver  thereof,  nor shall any single or partial  exercise by the Holder of any
right,  remedy or power  hereunder  preclude any other or future exercise of any
other  right,  remedy or power.  Each and every  right,  remedy or power  hereby
granted  to the  Holder  or  allowed  it by  law or  other  agreement  shall  be
cumulative  and not  exclusive of any other,  and may be exercised by the Holder

Statements  in  compliance  with the 1933 Act and pursuant to Rule 415 under the

      (b)   REGISTRATION.
            -------------

            (i) Mandatory  Registration.  The Company shall prepare,  and, on or
prior to 90 days after the date of issuance of the relevant Debentures, Warrants
and  Placement  Warrants,   file  with  the  SEC  a  Registration  Statement  or
Registration  Statements  (as is  necessary)  on Form S-3 (or,  if such  form is
unavailable for such a registration, on such other form as is available for such
a  registration,  subject to the consent of the Investors  holding a majority of
the  Registrable  Securities and the  provisions of Section 2(c),  which consent
will  not  be  unreasonably  withheld),  covering  the  resale  of  all  of  the
Registrable  Securities,  which  Registration  Statement(s) shall state that, in
accordance  with Rule 416  promulgated  under the 1933  Act,  such  Registration
Statement(s) also covers such intermediate number of additional shares of Common
Stock as may become issuable upon conversion of the Debentures and upon exercise
of the Warrants and Placement  Warrants (i) to prevent  dilution  resulting from


                                   - 2 -




<PAGE>


Exhibit 4.3

stock  splits,  stock  dividends or similar  transactions  and (ii) by reason of
changes in the  Conversion  Price or Conversion  Rate of the  Debentures and the
Exercise Price of the Warrants and the Exercise Price of the Placement  Warrants
in  accordance  with  the  terms  thereof.  Such  Registration  Statement  shall
initially  register  for resale at least such  number of shares of Common  Stock
equal to the number of relevant Conversion Shares,  Warrant Shares and Placement
Warrant  Shares,  subject  to  adjustment  as  provided  in Section  3(b).  Such
registered  shares of Common Stock shall be allocated  among the  Investors  pro
rata based on the total number of Registrable  Securities  issued or issuable as
of each date that a Registration Statement,  as amended,  relating to the resale
of the  Registrable  Securities  is declared  effective  by the SEC. The Company
shall  use its best  efforts  to have  the  Registration  Statement(s)  declared
effective by the SEC as soon as practicable, but in no event later than 150 days
after the issuance of the relevant Debentures,  Warrants and Placement Warrants.
The Company or any other holder of the Company's securities who has registration
rights (other than the Investors and their assignees or transferees) may include
its securities in an aggregate  amount not to exceed 100,000 in any registration
effected pursuant to this Section 2(a); provided,  however, that at such time as
the total number of  Registrable  Securities  held by the Investors is less than
ten  percent  (10%)  of an  amount  equal to the  total  number  of  Registrable
Securities  covered by the Registration  Statement(s)  described in this Section
2(a) less the number of  securities  of the  Company or any other  holder of the
Company's  securities  included in such Registration  Statement(s) as previously
described,  the Company  shall not be limited in any manner with  respect to the
number of securities to be covered by such Registration Statement(s).

            (ii)  Counsel  and  Investment  Bankers.  Subject  to  Section 5, in
connection with any offering pursuant to Section 2, the Investors shall have the
right to select  one legal  counsel  and an  investment  banker or  bankers  and
manager  or  managers  to  administer  their  interest  in the  offering,  which
investment  banker  or  bankers  or  manager  or  managers  shall be  reasonably
satisfactory  to the Company.  The Company shall  reasonably  cooperate with any
such counsel and  investment  bankers.  The Investors  shall pay all expenses of
such counsel, investment bankers and managers.

            (iii)  Piggy-Back  Registrations.  If a  Registration  Statement  in
compliance with this Agreement is not effective,  and prior to the expiration of
the Registration Period (as hereinafter  defined),  the Company proposes to file
with  the SEC a  Registration  Statement  relating  to an  offering  for its own
account  or the  account of others  under the 1933 Act of any of its  securities
(other than (i) a  Registration  Statement on Form S-4 or Form S-8 or their then
equivalents  relating to securities  to be issued solely in connection  with any
acquisition  of any entity or business  securities  issuable in connection  with
stock option or other employee  benefit plans or (ii) a  Registration  Statement
relating to the sale of securities  pursuant to Rule 145  promulgated  under the
1933 Act),  the Company shall  promptly send to each Investor who is entitled to
registration  rights under this Section 2(c), at least twenty (20) days prior to
the  anticipated  date of filing,  written notice of the Company's  intention to


                                   - 3 -




<PAGE>


Exhibit 4.3

file a Registration  Statement and of such Investor's  rights under this Section
2(c) and, if within twenty (20) days after receipt of such notice, such Investor
shall so request in writing,  the  Company  shall  include in such  Registration
Statement the Registrable  Securities  such Investor  requests to be registered,
subject to the priorities set forth in Section 2(d). No right to registration of
Registrable  Securities  under this Section 2(c) shall be construed to limit any
registration  required under Section 2(a). The  obligations of the Company under
this  Section  2(c)  may be  waived  by  Investors  holding  a  majority  of the
Registrable  Securities.  If an offering in connection with which an Investor is
entitled to registration  under this Section 2(c) is an  underwritten  offering,
then  each  Investor   whose   Registrable   Securities  are  included  in  such
Registration  Statement shall unless otherwise agreed by the Company,  offer and
sell such  Registrable  Securities in an  underwritten  offering  using the same
underwriter or underwriters and, subject to the provisions of this Agreement, on
the same terms and  conditions as other shares of Common Stock  included in such
underwritten offering.

            (iv) Priority in Piggy-Back  Registration  Rights in connection with
Registrations  for Company Account.  If the registration  referred to in Section
2(c) is to be an underwritten  public  offering and the managing  underwriter(s)
advise the  Company in writing,  that in their  reasonable  good faith  opinion,
marketing or other factors  dictate that a limitation on the number of shares of
Common  Stock  which may be included in the  Registration  Statement  (which may
include a total  "cut-back"  of all  Registrable  Securities)  is  necessary  to
facilitate  and not  adversely  affect the proposed  offering,  then the Company
shall  include in such  registration:  (1) first,  all  securities  the  Company
proposes  to sell for its own  account,  (2)  second,  up to the full  number of
securities  proposed  to be  registered  for  the  account  of  the  holders  of
securities  entitled  to  inclusion  of  their  securities  in the  Registration
Statement by reason of demand registration rights, and (3) third, the securities
requested to be  registered  by the  Investors  and other  holders of securities
entitled to participate in the registration,  as of the date hereof,  drawn from
them pro rata based on the number  each has  requested  to be  included  in such
registration.

            (v)  Eligibility  for Form S-3.  In the  event  that Form S-3 is not
available for the sale by the Investors of the Registrable Securities,  then the
Company  (i) with  the  consent  of the  Investors  holding  a  majority  of the
Registrable  Securities  pursuant to Section 2(a),  shall,  in  accordance  with
Section  2(a),  register  the  sale of the  Registrable  Securities  on  another
appropriate   form  and  (ii)  the  Company  shall  undertake  to  register  the
Registrable  Securities on Form S-3 as soon as such form is available,  provided
that the Company shall maintain the effectiveness of the Registration  Statement
then in effect, if any, until such time as a Registration  Statement on Form S-3
covering the Registrable Securities has been declared effective by the SEC.

            (vi) Liquidated  Damages. If pursuant to Section 2(a) a Registration
Statement is not (i) filed with the SEC on or prior to 90 days after the date of
issuance of the relevant Debentures,  the Warrants and the Placement Warrants or


                                   - 4 -




<PAGE>


Exhibit 4.3

(ii)  declared  effective  within  150 days  after the date of  issuance  of the
relevant  Debentures,  Warrants and  Placement  Warrants  (each a  "Registration
Default"),  the  Company  agrees  to pay to  each  Investor  liquidated  damages
("Liquidated  Damages") in an amount equal to two percent (2%) of the  principal
amount of the relevant  Debentures  per month.  All accrued  Liquidated  Damages
shall be paid to the  affected  Investors  by the  Company by wire  transfer  of
immediately available funds on the first calendar day of each month, except that
if such date is not a  business  day,  then the next  business  day  immediately
following  such date.  As of the date of the cure of all  Registration  Defaults
relating to any  particular  Registrable  Securities,  the accrual of Liquidated
Damages with respect to such Registrable Securities will cease.

            (vii) Limitation on Registration  Rights.  Notwithstanding  anything
contained in this Agreement to the contrary,  when, in the opinion of counsel to
the Company  (which  counsel shall be  experienced  in securities  law matters),
registration of the  Registrable  Securities is not required by the 1933 Act and
other  applicable  securities  laws in  connection  with a proposed sale of such
Registrable  Securities,  an  Investor  shall  have no rights  pursuant  to this
Section 2 to request registration in connection with such proposed sale, and the
Company shall promptly  provide to the transfer agent and the Investor's  broker
in  connection  with any sale  transaction  an  opinion  to the effect set forth
above.

      (c)   RELATED OBLIGATIONS.
            --------------------

      Whenever an Investor has  requested  that any  Registrable  Securities  be
registered  pursuant to Section 2(c) or at such time as the Company is obligated
to file a  Registration  Statement  with the SEC pursuant to Section  2(a),  the
Company will use its best efforts to effect the  registration of the Registrable
Securities in accordance  with the intended  method of disposition  thereof and,
pursuant thereto, the Company shall have the following obligations:

            (i) The  Company  shall  promptly  prepare  and file  with the SEC a
Registration Statement with respect to the Registrable Securities on or prior to
the ninetieth (90th) day after the date of issuance of any Debentures,  Warrants
and Placement Warrants for the registration of Registrable  Securities  pursuant
to Section  2(a) and use its best efforts to cause such  Registration  Statement
relating to the Registrable  Securities to become  effective as soon as possible
after such filing (but in no event later than 150 days after the issuance of any
Debentures,  Warrants and Placement Warrants for the registration of Registrable
Securities  pursuant  to Section  2(a)),  and keep such  Registration  Statement
effective pursuant to Rule 415 at all times until the earlier of (i) the date as
of  which  the  Investors  may sell all of the  Registrable  Securities  without
restriction  pursuant to Rule 144(k) (or its then equivalent)  promulgated under
the 1933 Act or (ii) the date on which (A) the Investors shall have sold all the
Registrable  Securities and (B) none of the  Debentures,  Warrants and Placement
Warrants  is  outstanding  (the  "Registration   Period"),   which  Registration
Statement  (including  any amendments or  supplements  thereto and  prospectuses


                                   - 5 -




<PAGE>


Exhibit 4.3

contained  therein) shall not contain any untrue statement of a material fact or
omit to state a material  fact  required to be stated  therein,  or necessary to
make the statements  therein,  in light of the  circumstances in which they were
made, not misleading.

            (ii) Subject to Section  3(f),  the Company  shall  prepare and file
with  the  SEC  such  amendments  (including   post-effective   amendments)  and
supplements  to a Registration  Statement and the  prospectus  forming a part of
such  Registration  Statement,  which prospectus is to be filed pursuant to Rule
424  promulgated  under  the  1933  Act,  as  may  be  necessary  to  keep  such
Registration  Statement  effective at all times during the Registration  Period,
and, during such period, comply with the provisions of the 1933 Act with respect
to the disposition of all Registrable  Securities of the Company covered by such
Registration Statement until such time as such Registrable Securities shall have
been disposed of in accordance  with the intended  methods of disposition by the
seller or sellers thereof as set forth in such  Registration  Statement.  In the
event the  number of  shares  available  under a  Registration  Statement  filed
pursuant  to this  Agreement  is  insufficient  to cover all of the  Registrable
Securities,  the Company shall amend such Registration  Statement, or file a new
Registration Statement (on the short form available therefor, if applicable), or
both, so as to cover all of the Registrable Securities, in each case, as soon as
practicable,  but in any event  within  fifteen  (15)  business  days  after the
necessity  therefor  arises  (based on the market  price of the Common Stock and
other  relevant  factors on which the Company  reasonably  elects to rely).  The
Company  shall  use  its  best  efforts  to  cause  such  amendment  and/or  new
Registration  Statement to become  effective as soon as  reasonably  practicable
following  the filing  thereof.  For purposes of the  foregoing  provision,  the
number  of  shares  available  under a  Registration  Statement  shall be deemed
"insufficient  to cover all of the  Registrable  Securities"  if at any time the
number of  Registrable  Securities  issued or issuable  upon  conversion  of the
Debentures, the Warrants and the Placement Warrants is greater than the quotient
determined  by dividing (i) the number of shares of Common Stock  available  for
resale  under such  Registration  Statement  by (ii) 1.5.  For  purposes  of the
calculation  set  forth  in the  foregoing  sentence,  any  restrictions  on the
convertibility  of the  Debentures  and the  exercise  of the  Warrants  and the
Placement  Warrants shall be disregarded and such calculation  shall assume that
the  Debentures  are then  convertible  into shares of Common  Stock at the then
prevailing  Conversion  Rate (as  defined in the  certificate  representing  the
Debentures)  and the Warrants and the  Placement  Warrants are then  exercisable
into shares of Common Stock at the prevailing  Exercise Price, as applicable (as
defined  in the  certificate  representing  the  Warrants  and  the  certificate
representing the Placement Warrants).

            (iii) The Company shall furnish to each Investor  whose  Registrable
Securities  are included in any  Registration  Statement  and its legal  counsel
without charge (i) promptly after the same is prepared and filed with the SEC at
least one copy of such  Registration  Statement  and any  amendment(s)  thereto,
including financial statements and schedules, all documents incorporated therein
by reference  and all exhibits,  the  prospectus  included in such  Registration
Statement  (including  each  preliminary  prospectus)  and,  with regard to such


                                   - 6 -

Registration Statement(s),  any correspondence by or on behalf of the Company to
the SEC or the staff of the SEC and any correspondence from the SEC or the staff
of the SEC to the Company or its representatives, (ii) upon the effectiveness of
any Registration  Statement,  ten (10) copies of the prospectus included in such
Registration Statement and all amendments and supplements thereto (or such other
number of copies as such Investor may  reasonably  request) and (iii) such other
documents, including any preliminary prospectus, as such Investor may reasonably
request in order to facilitate  the  disposition of the  Registrable  Securities
owned by such Investor.

            (iv) The Company  shall use  reasonable  efforts to (i) register and
qualify the  Registrable  Securities  covered by a Registration  Statement under
such other  securities  or "blue sky" laws of such  jurisdictions  in the United
States as any  Investor  reasonably  requests,  (ii)  prepare  and file in those
jurisdictions,   such  amendments  (including  post-effective   amendments)  and
supplements  to such  registrations  and  qualifications  as may be necessary to
maintain the effectiveness  thereof during the Registration  Period,  (iii) take
such other  actions as may be  necessary  to  maintain  such  registrations  and
qualifications in effect at all times during the Registration  Period,  and (iv)
take all  other  actions  reasonably  necessary  or  advisable  to  qualify  the
Registrable Securities for sale in such jurisdictions;  provided,  however, that
the  Company  shall not be required in  connection  therewith  or as a condition
thereto to (x)  qualify to do business  in any  jurisdiction  where it would not
otherwise be required to qualify but for this Section 3(d),  (y) subject  itself
to general taxation in any such  jurisdiction,  or (z) file a general consent to
service of process in any such  jurisdiction.  The Company shall promptly notify
each Investor who holds Registrable  Securities of the receipt by the Company of
any  notification  with  respect  to  the  suspension  of  the  registration  or
qualification of any of the Registrable Securities for sale under the securities
or "blue sky" laws of any  jurisdiction  in the United  States or its receipt of
actual  notice of the  initiation  or  threatening  of any  proceeding  for such
purpose.

            (v) Intentionally omitted.

            (vi) As promptly as practicable  after becoming aware of such event,
the Company  shall notify each Investor in writing of the happening of any event
as a result of which the  prospectus  included in a Registration  Statement,  as
then in effect,  includes an untrue  statement of a material fact or omission to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein,  in light of the circumstances  under which they were made,
not  misleading,  and  promptly  prepare  a  supplement  or  amendment  to  such
Registration Statement to correct such untrue statement or omission, and deliver
ten (10) copies of such  supplement or amendment to each Investor (or such other
number of copies as such  Investor may  reasonably  request).  The Company shall
also  promptly  notify each  Investor in writing  (i) when a  prospectus  or any
prospectus  supplement or  post-effective  amendment has been filed,  and when a
Registration  Statement or any  post-effective  amendment  has become  effective
(notification  of such  effectiveness  shall be  delivered  to each  Investor by
facsimile on the same day of such  effectiveness and by overnight mail), (ii) of


                                   - 7 -

Exhibit 4.3

any request by the SEC for amendments or supplements to a Registration Statement
or  related  prospectus  or  related  information,  and  (iii) of the  Company's
reasonable  determination  that a  post-effective  amendment  to a  Registration
Statement would be appropriate. Notwithstanding anything to the contrary in this
Section  3(f),  at any time after the  Registration  Statement has been declared
effective,  the Company may delay the disclosure of any  information  concerning
the Company if the Board of  Directors of the Company  determines  in good faith
that in its reasonable  business judgment such disclosure would interfere in any
material respect with any financing,  acquisition,  corporate  reorganization or
other  transaction or  development  involving the Company that in the reasonable
good faith business  judgment of such board is a transaction or development that
is or would be  material  to the  Company  and, in the opinion of counsel to the
Company, such disclosure is not otherwise required (a "Grace Period"); provided,
that the  Company  shall  promptly  (i) notify the  Investors  in writing of the
existence of material  non-public  information giving rise to a Grace Period and
the date on which the Grace Period will begin,  and (ii) notify the Investors in
writing of the date on which the Grace Period ends; and, provided further,  that
(A) during any  consecutive  120 day period,  the Grace  Period shall not exceed
thirty (30) calendar days in the aggregate,  and (B) during any  consecutive 365
day period,  the Grace Period shall not exceed  forty-five (45) calendar days in
the aggregate, and (C) there has been no Underwriting Lock-Up Period (as defined
in  the  Securities  Purchase  Agreement)  in the 20  day  period  prior  to the
Company's notice to the Investors of a Grace Period. For purposes of determining
the length of a Grace Period above,  the Grace Period shall begin on and include
the date the  holders  receive  the  notice  referred  to in clause  (i) of this
Section  3(f) and shall end on and  include  the date the  holders  receive  the
notice  referred to in clause (ii) of this Section 3(f).  Upon expiration of the
Grace  Period,  the Company  shall again be bound by the first  sentence of this
Section 3(f) with respect to the information giving rise thereto.

            (vii) The Company shall use its best efforts to prevent the issuance
of any  stop  order or  other  suspension  of  effectiveness  of a  Registration
Statement,  or the  suspension of the  qualification  of any of the  Registrable
Securities for sale in any  jurisdiction  and, if such an order or suspension is
issued,  to obtain the  withdrawal  of such order or  suspension at the earliest
possible  moment and to notify each  Investor who holds  Registrable  Securities
being  sold of the  issuance  of such  order and the  resolution  thereof or its
receipt of actual notice of the  initiation or threat of any proceeding for such
purpose.

            (viii) The Company  shall permit each  Investor and a single firm of
counsel,  initially Kramer,  Levin,  Naftalis & Frankel or such other counsel as
thereafter designated as selling stockholders' counsel by the Investors who hold
a majority of the Registrable  Securities being sold, to review and comment upon
a Registration  Statement and all amendments  and  supplements  thereto at least
seven business days prior to their filing with the SEC.

            (ix) At the  request of the  Investors  who hold a  majority  of the
Registrable  Securities  being sold,  the Company  shall use its best efforts to


                                   - 8 -

Exhibit 4.3

furnish,  on the date that  Registrable  Securities  are  delivered  for sale in
connection with the Registration Statement an opinion, dated as of such date, of
counsel  representing the Company for purposes of such  Registration  Statement,
addressed to the Investors.

            (x) The Company shall make  reasonably  available for  inspection by
(i) any Investor, (ii) any underwriter participating in any disposition pursuant
to a  Registration  Statement,  (iii)  one  firm of  attorneys  and one  firm of
accountants  or other  agents  retained by the  Investors,  and (iv) one firm of
attorneys retained by all such underwriters (collectively, the "Inspectors") all
pertinent  financial and other records,  and pertinent  corporate  documents and
properties of the Company  (collectively the "Records"),  as shall be reasonably
deemed  necessary by each Inspector to enable each Inspector to exercise its due
diligence  responsibility,  and  cause the  Company's  officers,  directors  and
employees to supply all information  which any Inspector may reasonably  request
for purposes of such due diligence; provided, however, that each Inspector shall
hold in confidence and shall not make any disclosure  (except to an Investor) or
use of any Record or other  information  which the  Company  determines  in good
faith to be  confidential,  and of which  determination  the  Inspectors  are so
notified in writing,  unless (a) the  disclosure of such Records is necessary to
avoid or correct a misstatement or omission in any Registration  Statement or is
otherwise  required  under the 1933 Act,  (b) the  release  of such  Records  is
ordered  pursuant to a final,  non-appealable  subpoena or order from a court or
government  body  of  competent  jurisdiction,  or (c) the  information  in such
Records has been made generally available to the public other than by disclosure
in  violation  of this  or any  other  agreement  of  which  the  Inspector  has
knowledge.  The  Company  shall not be required  to  disclose  any  confidential
information in such Record to an Inspector unless and until such Inspector shall
have  entered  into a  confidentiality  agreement  with the Company with respect
thereto,  substantially  in accordance with the provisions of this Section 3(j).
Each Investor shall agree that, upon learning that disclosure of such Records is
sought  in or by a court  or  governmental  body of  competent  jurisdiction  or
through  other  means,  it will give prompt  notice to the Company and allow the
Company, at its expense,  to undertake  appropriate action to prevent disclosure
of, or to obtain a protective  order for, the Records deemed  confidential.  The
Investors shall pay all costs and expenses incurred by the Company in connection
with its obligations under this Section 3(j).

            (xi)  The  Company  shall  hold  in  confidence  and  not  make  any
disclosure of information  concerning an Investor provided to the Company unless
(i)  disclosure of such  information  is necessary to comply with any federal or
state  securities  law, (ii) the disclosure of such  information is necessary to
avoid or correct a misstatement or omission in any Registration Statement, (iii)
the  release of such  information  is ordered  pursuant  to a subpoena  or other
final,  non-appealable  order  from a court or  governmental  body of  competent
jurisdiction,  or (iv) such information has been made generally available to the
public other than by  disclosure  in  violation  of this  Agreement or any other
agreement.  The Company agrees that it shall,  upon learning that  disclosure of


                                   - 9 -

Exhibit 4.3

such  information  concerning  an  Investor  is  sought  in  or  by a  court  or
governmental body of competent  jurisdiction or through other means, give prompt
written  notice to such  Investor  and allow such  Investor,  at the  Investor's
expense, to undertake  appropriate action to prevent disclosure of, or to obtain
a protective order for, such information.

            (xii) The  Company  shall  use its best  efforts  (i) to secure  the
inclusion for  quotation on the Nasdaq  SmallCap  Market or the Nasdaq  National
Market,  as  applicable,  for  all  the  Registrable  Securities  covered  by  a
Registration Statement and, without limiting the generality of the foregoing, to
arrange for at least two market makers to register with the National Association
of Securities Dealers, Inc. as such with respect to such Registrable  Securities
or (ii) to cause  such  Registrable  Securities  to be  listed or traded on each
securities  exchange or automated  quotation  system on which  securities of the
same class or series issued by the Company are then listed or traded, if any, if
the listing or trading of such  Registrable  Securities is then permitted  under
the rules of such exchange or automated  quotation system. The Company shall pay
all fees and expenses in connection  with  satisfying its obligation  under this
section 3(l).

            (xiii) The  Company  shall  cooperate  with the  Investors  who hold
Registrable  Securities  being offered to facilitate the timely  preparation and
delivery of certificates (not bearing any restrictive  legend)  representing the
Registrable  Securities to be offered  pursuant to a Registration  Statement and
enable such certificates to be in such denominations or amounts, as the case may
be, as the Investors may reasonably  request and registered in such names as the
Investors may request.

            (xiv) The Company shall  provide a transfer  agent and registrar for
all such  Registrable  Securities  not  later  than the  effective  date of such
Registration Statement.

            (xv) If requested by Investors holding a majority of the Registrable
Securities,  the  Company  shall (i)  immediately  incorporate  in a  prospectus
supplement  or  post-effective  amendment  such  information  as  the  Investors
reasonably   agree  should  be  included   therein  relating  to  the  sale  and
distribution of Registrable  Securities;  (ii) make all required filings of such
prospectus  supplement  or  post-effective  amendment as soon as notified of the
matters to be  incorporated  in such  prospectus  supplement  or  post-effective
amendment; and (iii) supplement or make amendments to any Registration Statement
if requested by Investors holding a majority of the Registrable Securities.

            (xvi)  The  Company   shall  use  its  best  efforts  to  cause  the
Registrable  Securities covered by the applicable  Registration  Statement to be
registered with or approved by such other  governmental  agencies or authorities
as  may  be  necessary  to  consummate  the  disposition  of  such   Registrable
Securities.

Exhibit 4.3

            (xvii) The Company  shall make  generally  available to its security
holders as soon as practical,  but not later than 90 days after the close of the
period  covered  thereby,  an earnings  statement  (in form  complying  with the
provisions of Section 11(a) of the 1933 Act and Rule 158 promulgated thereunder)
covering a  twelve-month  period  beginning  not later than the first day of the
Company's  fiscal quarter next following the effective date of the  Registration

Company shall deliver, and shall cause legal counsel for the Company to deliver,

Investors  whose  Registrable  Securities  are  included  in  such  Registration
Statement)  confirmation  that the  Registration  Statement  has  been  declared
effective by the SEC in the form attached hereto as Exhibit A.

      (d)   OBLIGATIONS OF THE INVESTORS.
            -----------------------------

            (i) At least  seven (7) days prior to the first  anticipated  filing
date of a  Registration  Statement,  the Company  shall notify each  Investor in
writing of the information the Company  requires from each such Investor if such
Investor elects to have any of such Investor's  Registrable  Securities included
in such  Registration  Statement.  It  shall  be a  condition  precedent  to the
obligations  of the  Company  to  complete  the  registration  pursuant  to this
Agreement with respect to the  Registrable  Securities of a particular  Investor
that such  Investor  shall  furnish to the Company  such  information  regarding
itself,  the  Registrable  Securities  held by it and  the  intended  method  of
disposition  of the  Registrable  Securities  held by it as shall be  reasonably
required to effect the  registration  of such  Registrable  Securities and shall
execute such documents in connection  with such  registration as the Company may
reasonably request.

            (ii) Each Investor, by such Investor's acceptance of the Registrable
Securities,  agrees to cooperate with the Company as reasonably requested by the
Company  in  connection  with the  preparation  and  filing of any  Registration

such  Investor's  election  to  exclude  all  of  such  Investor's   Registrable
Securities from such Registration Statement.

            (iii)  In  the  event  any  Investor  elects  to  participate  in an
underwritten public offering pursuant to Section 2, each such Investor agrees to
enter  into and  perform  such  Investor's  obligations  under  an  underwriting
agreement, in usual and customary form, including, without limitation, customary
indemnification  and contribution  obligations  (only with respect to violations
which occur in reliance upon and in  conformity  with  information  furnished in
writing to the Company by such Investor  expressly  for use in the  Registration

of such offering and take such other actions as are  reasonably  required by the
Company in order to expedite or facilitate the  disposition  of the  Registrable
Securities,  unless  such  Investor  notifies  the  Company  in  writing of such
Investor's  election to exclude all of such  Investor's  Registrable  Securities
from such Registration Statement.

            (iv) Each Investor  agrees that, upon receipt of any notice from the
Company of the  happening of any event of the kind  described in Section 3(g) or
the  first  sentence  of  3(f),  such  Investor  will  immediately   discontinue
disposition of Registrable Securities pursuant to any Registration  Statement(s)
covering such Registrable Securities until such Investor's receipt of the copies
of the  supplemented or amended  prospectus  contemplated by Section 3(g) or the
first sentence of 3(f).

            (v) No Investor may  participate  in any  underwritten  registration
hereunder  unless such Investor (i) agrees to sell such  Investor's  Registrable
Securities on the basis provided in any  underwriting  arrangements  approved by
the Company and the Investors  entitled  hereunder to approve such arrangements,
(ii) completes and executes all questionnaires, powers of attorney, indemnities,
underwriting  agreements and other documents reasonably required under the terms
of such underwriting arrangements, and (iii) agrees to pay its pro rata share of
all underwriting discounts and commissions.

      (e)   EXPENSES OF REGISTRATION.
            -------------------------

            Except as  otherwise  provided  in this  Agreement,  all  reasonable
expenses  incurred in connection with  registrations,  filings or qualifications
pursuant to Sections 2 and 3, including,  without limitation,  all registration,
listing  and  qualifications  fees,  printers  and  accounting  fees,  fees  and
disbursements  of counsel and  accountants  for the Company shall be paid by the
Company,  whether or not any registration  statement becomes  effective.  In the

offering of any Registrable Securities, all fees, costs, charges and expenses of
such underwriters in the offering shall be paid by the Investors. Any fees to be
paid by the  Investors  pursuant to this  Agreement  shall be paid on a pro rata
basis among the Investors.

      (f)   INDEMNIFICATION.
            ----------------

            In  the  event  any   Registrable   Securities  are  included  in  a
Registration Statement under this Agreement:

            (i) To the fullest  extent  permitted by law, the Company will,  and
hereby does,  indemnify,  hold  harmless and defend each Investor who holds such

and each Person,  if any, who controls,  any Investor  within the meaning of the
1933 Act or the  Securities  Exchange  Act of 1934,  as amended (the "1934 Act")
(each,  an  "Indemnified  Person"),   against  any  losses,   claims,   damages,
liabilities,  judgments,  fines,  penalties,  charges,  costs,  attorneys' fees,
amounts  paid in  settlement  or  expenses,  joint  or  several,  (collectively,
"Claims") incurred in investigating,  preparing or defending any action,  claim,
suit, inquiry,  proceeding,  investigation or appeal taken from the foregoing by
or before any court or governmental,  administrative or other regulatory agency,
body or the SEC,  whether  pending or threatened,  whether or not an indemnified
party is or may be a party thereto ("Indemnified Damages"), to which any of them
may become subject  insofar as such Claims (or actions or  proceedings,  whether
commenced or threatened, in respect thereof) arise out of or are based upon: (i)
any  untrue  statement  or alleged  untrue  statement  of a  material  fact in a
Registration Statement or any post-effective  amendment thereto or in any filing
made in connection with the  qualification  of the offering under the securities
or other "blue sky" laws of any jurisdiction in which Registrable Securities are
offered  ("Blue Sky  Filing"),  or the  omission or alleged  omission to state a
material fact required to be stated  therein or necessary to make the statements
therein,  in light of the circumstances  under which the statements therein were
made, not misleading, (ii) any untrue statement or alleged untrue statement of a
material  fact  contained  in any  preliminary  prospectus  if used prior to the
effective  date  of such  Registration  Statement,  or  contained  in the  final
prospectus  (as  amended or  supplemented,  if the Company  files any  amendment
thereof or supplement  thereto with the SEC) or the omission or alleged omission
to state  therein  any  material  fact  necessary  to make the  statements  made
therein,  in light of the circumstances  under which the statements therein were
made, not misleading, or (iii) any violation or alleged violation by the Company
of the 1933 Act, the 1934 Act, any other law, including, without limitation, any
state securities law, or any rule or regulation thereunder relating to the offer
or sale of the Registrable  Securities pursuant to a Registration Statement (the
matters  in  the  foregoing  clauses  (i)  through  (iii)  being,  collectively,
"Violations").  Subject  to the  restrictions  set  forth in  Section  6(d) with
respect  to the  number  of legal  counsel,  the  Company  shall  reimburse  the
Indemnified  Persons  promptly as such  expenses  are  incurred  and are due and
payable,  for any reasonable legal fees or other reasonable expenses incurred by
them  in   connection   with   investigating   or  defending   any  such  Claim.
Notwithstanding  anything to the contrary contained herein, the  indemnification
agreement contained in this Section 6(a): (i) shall not apply to a Claim arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with information  furnished in writing to the Company by any Indemnified  Person
or its  counsel,  agent  or  representative  for  use  in  connection  with  the
preparation  of the  Registration  Statement  or any such  amendment  thereof or
supplement  thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c); and (ii) shall not apply to amounts paid in settlement
of any Claim if such settlement is effected without the prior written consent of
the Company,  which consent shall not be unreasonably  withheld.  Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on behalf of the  Indemnified  Person  and shall  survive  the  transfer  of the
Registrable  Securities by the Investors pursuant to Section 9.  Notwithstanding
anything  to  the  contrary  contained  herein,  the  indemnification  agreement


                                   - 13 -




<PAGE>


Exhibit 4.3

contained in this Section 6(a) with respect to any preliminary  prospectus shall
not inure to the benefit of any  Indemnified  Person if the untrue  statement or
omission of material fact contained in the preliminary  prospectus was corrected
on a timely basis in the prospectus, as then amended or supplemented.

            (ii) In  connection  with  any  Registration  Statement  in which an
Investor  is  participating,  each such  Investor  agrees to  severally  and not
jointly indemnify,  hold harmless and defend, to the same extent and in the same
manner as is set forth in Section 6(a), the Company, each of its directors, each
of its officers who signs the Registration  Statement,  each Person, if any, who
controls  the  Company  within  the  meaning  of the  1933  Act or the  1934 Act
(collectively and together with an Indemnified Person, an "Indemnified  Party"),
against  any  Claim  or  Indemnified  Damages  to which  any of them may  become
subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim or
Indemnified  Damages arise out of or are based upon (i) any  Violation,  in each
case to the  extent,  and only to the  extent,  that  such  Violation  occurs in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by such Investor for use in connection with such Registration  Statement
or (ii) any action or failure to act of an underwriter selected by the Investors
pursuant to Section  2(b);  and,  subject to Section  6(d),  such  Investor will
reimburse any legal or other expenses  reasonably incurred by them in connection
with  investigating  or defending any such Claim;  provided,  however,  that the
indemnity  agreement  contained  in this  Section  6(b) and the  agreement  with
respect to  contribution  contained in Section 7 shall not apply to amounts paid
in  settlement  of any Claim if such  settlement  is effected  without the prior
written  consent  of such  Investor,  which  consent  shall not be  unreasonably
withheld;  provided,  further,  however, that the Investor shall be liable under
this Section 6(b) for only that amount of a Claim or Indemnified Damages as does
not  exceed  the net  proceeds  to such  Investor  as a  result  of the  sale of
Registrable Securities pursuant to such Registration  Statement.  Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on  behalf of such  Indemnified  Party and shall  survive  the  transfer  of the
Registrable  Securities by the Investors pursuant to Section 9.  Notwithstanding
anything  to  the  contrary  contained  herein,  the  indemnification  agreement
contained in this Section 6(b) with respect to any preliminary  prospectus shall
not inure to the benefit of any  Indemnified  Party if the untrue  statement  or
omission of material fact contained in the preliminary  prospectus was corrected
on a timely basis in the prospectus, as then amended or supplemented.

            (iii) The  Company  shall be entitled  to receive  indemnities  from
underwriters,  selling brokers,  dealer managers and similar securities industry
professionals participating in any distribution,  to the same extent as provided
above,  with  respect  to  information  such  persons  so  furnished  in writing
expressly for inclusion in the Registration Statement.

            (iv) Promptly after receipt by an Indemnified  Person or Indemnified
Party  under  this  Section  6 of notice of the  commencement  of any  action or
proceeding  (including any governmental action or proceeding) involving a Claim,


                                   - 14 -

Exhibit 4.3

such  Indemnified  Person or  Indemnified  Party  shall,  if a Claim in  respect
thereof is to be made  against  any  indemnifying  party  under this  Section 6,
deliver to the indemnifying party a written notice of the commencement  thereof,
and the  indemnifying  party shall have the right to participate in, and, to the
extent the indemnifying  party so desires,  jointly with any other  indemnifying
party similarly  noticed,  to assume control of the defense thereof with counsel
mutually  satisfactory to the indemnifying  party and the Indemnified  Person or
the  Indemnified  Party,  as  the  case  may  be;  provided,  however,  that  an
Indemnified  Person or Indemnified  Party shall have the right to retain its own
counsel with the fees and expenses to be paid by the indemnifying  party, if, in
the  reasonable  opinion of counsel  retained  by the  indemnifying  party,  the
representation  by such counsel of the Indemnified  Person or Indemnified  Party
and the  indemnifying  party would be  inappropriate  due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party  represented by such counsel in such  proceeding.  The Company shall
pay reasonable  fees for only one separate legal counsel for the Investors,  and
such legal  counsel  shall be  selected by the  Investors  holding a majority in
interest of the Registrable Securities included in the Registration Statement to
which the Claim  relates.  The  Indemnified  Party or  Indemnified  Person shall
cooperate fully with the  indemnifying  party in connection with any negotiation
or  defense  of any such  action  or claim by the  indemnifying  party and shall
furnish to the indemnifying  party all information  reasonably  available to the
Indemnified  Party or Indemnified  Person which relates to such action or claim.
The indemnifying  party shall keep the Indemnified  Party or Indemnified  Person
fully  apprised at all times as to the status of the  defense or any  settlement
negotiations with respect thereto. No indemnifying party shall be liable for any
settlement of any action,  claim, suit,  inquiry,  proceeding,  investigation or
appeal taken from the foregoing effected without its written consent,  provided,
however, that the indemnifying party shall not unreasonably  withhold,  delay or
condition its consent.  No indemnifying party shall,  without the consent of the
Indemnified  Party or  Indemnified  Person,  consent to entry of any judgment or
enter into any  settlement  or other  compromise  which  does not  include as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
Indemnified  Party or  Indemnified  Person of a release  from all  liability  in
respect to such action,  claim,  suit,  inquiry,  proceeding,  investigation  or
appeal  taken from the  foregoing.  Following  indemnification  as provided  for
hereunder,  the  indemnifying  party  shall be  subrogated  to all rights of the
Indemnified Party or Indemnified  Person with respect to all Persons relating to
the  matter for which  indemnification  has been  made.  The  failure to deliver
written  notice  to the  indemnifying  party  within  a  reasonable  time of the
commencement of any such action shall not relieve such indemnifying party of any
liability to the Indemnified  Person or Indemnified  Party under this Section 6,
except to the extent that the indemnifying party is materially prejudiced in its
ability to defend such action.

            (v) The indemnification  required by this Section 6 shall be made by
periodic  payments of the amount thereof during the course of the  investigation
or defense, as and when bills are received or Indemnified Damages are incurred.

Exhibit 4.3

            (vi) The indemnity  agreements contained herein shall be in addition
to (i) any  cause  of  action  or  similar  right  of the  Indemnified  Party or
Indemnified  Person  against  the  indemnifying  party or  others,  and (ii) any
liabilities the indemnifying party may be subject to pursuant to the law.

      (g)   CONTRIBUTION.
            -------------

            To the  extent  any  indemnification  by an  indemnifying  party  is
prohibited or limited by law, the indemnifying  party agrees to make the maximum
contribution  with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no contribution shall be made under  circumstances where the maker would not
have been  liable for  indemnification  under the fault  standards  set forth in
Section  6; (ii) no  seller  of  Registrable  Securities  guilty  of  fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution  from any seller of Registrable  Securities who was not
guilty of fraudulent misrepresentation;  and (ill) contribution by any seller of
Registrable  Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities.

      (h)   REPORTS UNDER THE 1934 ACT.

Rule 144 promulgated  under the 1933 Act or any other similar rule or regulation
of the SEC that may at any time permit the  Investors to sell  securities of the

            (i) make and keep public information  available,  as those terms are
understood and defined in Rule 144;

            (ii)  file with the SEC in a timely  manner  all  reports  and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company  remains  subject to such  requirements  (it being  understood  that
nothing herein shall limit the Company's  obligations  under Section 4(c) of the
Securities  Purchase  Agreement)  and the  filing  of  such  reports  and  other
documents is required for the applicable provisions of Rule 144; and

            (iii) furnish to Angelo,  Gordon & Co., as agent for the Buyers, and
the  Placement  Agent,  so long as any  Investor  owns  Registrable  Securities,
promptly  upon  request,  (i) a written  statement  by the  Company  that it has
complied  with the  reporting  requirements  of the 1934 Act, (ii) a copy of the

be reasonably requested to permit the Investors to sell such securities pursuant
to Rule 144 without registration.

      (i)   ASSIGNMENT OF REGISTRATION RIGHTS.
            ----------------------------------

            The rights under this Agreement shall be automatically assignable by
the Investors to any transferee of all or any portion of Registrable  Securities
if:  (i) the  Company  is,  within a  reasonable  time after  such  transfer  or
assignment,  furnished  with written  notice of (a) the name and address of such
transferee  or  assignee,  and (b) the  securities  with  respect  to which such
registration  rights are being  transferred  or assigned in accordance  with the
terms of the  Securities  Purchase  Agreement;  (ii) at or  before  the time the
Company  receives  such  written  notice the  transferee  or assignee  agrees in
writing with the Company to be bound by all of the provisions  contained herein,
including providing the Company with a current address for all required notices;
(iii) such  transfer  shall  have been made in  accordance  with the  applicable
requirements of the Securities Purchase Agreement, the Debentures,  the Warrants
and the Placement  Warrants;  and (iv) such  transferee  shall be an "accredited
investor" as that term is defined in Rule 501 of Regulation D promulgated  under
the 1933 Act.

      (j)   AMENDMENT OF REGISTRATION RIGHTS.
            ---------------------------------

            Provisions  of this  Agreement  may be  amended  and the  observance
thereof may be waived (either  generally or in a particular  instance and either
retroactively  or  prospectively),  only with the written consent of the Company
and Investors  who hold  two-thirds  (2/3) of the  Registrable  Securities.  Any
amendment or waiver effected in accordance with this Section 10 shall be binding
upon each Investor and the Company.

      (k)   MISCELLANEOUS.
            --------------

            (i) A person or  entity  is  deemed  to be a holder  of  Registrable
Securities  whenever  such  person or entity  owns of  record  such  Registrable
Securities.  If  the  Company  receives  conflicting  instructions,  notices  or
elections  from  two or more  persons  or  entities  with  respect  to the  same
Registrable  Securities,  the Company shall act upon the basis of  instructions,
notice  or  election  received  from the  registered  owner of such  Registrable
Securities.

            (ii) Any notices, consents, waivers or other communications required
or  permitted to be given under the terms of this  Agreement  must be in writing
and will be deemed to have  been  delivered  (i) upon  receipt,  when  delivered
personally;  (ii) upon receipt,  when sent by facsimile (provided a confirmation
of  transmission  is  mechanically  generated  and  kept on file by the  sending
party);  (iii) three (3) days after being sent by U.S.  certified  mail,  return

change in  address,  phone  number or  facsimile  number or the  person to whose
attention notices are to be sent.

            (iii)  Failure of any party to  exercise  any right or remedy  under
this  Agreement or otherwise,  or delay by a party in  exercising  such right or
remedy, shall not operate as a waiver thereof.

            (iv)  This  Agreement  shall  be  governed  by  and  interpreted  in
accordance  with  the  laws of the  State  of New  York  without  regard  to the
principles  of conflict of laws.  Each party hereby  irrevocably  submits to the
non-exclusive  jurisdiction  of the state and federal courts sitting in the City

or in  connection  herewith  or with  any  transaction  contemplated  hereby  or
discussed herein, and hereby irrevocably waives, and agrees not to assert in any
suit, action or proceeding,  any claim that it is not personally  subject to the

improper.  Each party hereby  irrevocably waives personal service of process and
consents  to process  being  served in any such suit,  action or  proceeding  by
mailing a copy thereof to such party at the address for such notices to it under
this Agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof.  Nothing contained herein shall be deemed
to limit in any way any right to serve  process in any manner  permitted by law.
If any  provision of this  Agreement  shall be invalid or  unenforceable  in any
jurisdiction,  such invalidity or unenforceability shall not affect the validity
or enforceability of the remainder of this Agreement in that jurisdiction or the

forth or referred to herein and therein. This Agreement, the Securities Purchase
Agreement,  the Debentures and the Warrants  supersede all prior  agreements and
understandings  among the  Company  and the Buyers  with  respect to the subject
matter hereof and thereof.  This Agreement and the Placement Warrants constitute
the entire agreement between the Company and the Placement Agent with respect to

Agreement.

            (viii)  This  Agreement  may be  executed  in two or more  identical
counterparts,  each of which shall be deemed an original  but all of which shall

performed,  all such further acts and things,  and shall execute and deliver all
such other  agreements,  certificates,  instruments and documents,  as the other
party may reasonably request in order to carry out the intent and accomplish the

Securities,  determined as if all of the Debentures then  outstanding  have been
converted  into,  all of the Warrants  have been  exercised  for, and all of the
Placement Warrants have been exercised for, Registrable Securities.

            (xi) The language  used in this  Agreement  will be deemed to be the
language  chosen by the parties to express  their mutual  intent and no rules of

                        FORM OF NOTICE OF EFFECTIVENESS

Attn:

        Re:  Altair International Inc.
             -------------------------

Ladies and Gentlemen:

      We are counsel to Altair  International  Inc., an Ontario corporation (the
"Company"),  and have  represented  the Company in connection  with that certain
Securities  Purchase  Agreement (the "Purchase  Agreement")  entered into by and
among the Company and the buyers named  therein  (collectively,  the  "Holders")
pursuant  to  which  the  Company  issued  to the  Holders  its  5%  Convertible
Subordinated  Debentures due December __, 2001 (the  "Debentures"),  convertible
into shares of the Company's  common shares,  no par value (the "Common Stock"),
and warrants (the  "Warrants") to purchase  shares of Common Stock.  Pursuant to
the Purchase Agreement,  the Company also has entered into a Registration Rights
Agreement  with  the  Holders  and  Prudential   Securities   Incorporated  (the
"Registration  Rights  Agreement")  pursuant to which the Company agreed,  among
other  things,  to  register  the  Registrable  Securities  (as  defined  in the
Registration  Rights  Agreement),  including the shares of Common Stock issuable
upon  conversion of the  Debentures and the shares of Common Stock issuable upon
exercise  of  the  Warrants  and  the  Placement  Warrants  (as  defined  in the
Registration  Rights  Agreement),  under the  Securities Act of 1933, as amended
(the  "1933  Act").  In  connection  with the  Company's  obligations  under the
Registration Rights Agreement,  the Company filed a Registration  Statement (the
"Registration  Statement")  with the  Securities  and Exchange  Commission  (the
"SEC")  relating to the Registrable  Securities  which names each of the Holders
and Prudential Securities Incorporated as a selling stockholder thereunder.

      In connection with the foregoing, we advise you that a member of the SEC's
staff has advised us by  telephone  that the SEC has entered an order  declaring
the  Registration  Statement  effective  under  the 1933 Act at  [ENTER  TIME OF
EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,  after
telephonic  inquiry  of a  member  of the  SEC's  staff,  that  any  stop  order
suspending its  effectiveness  has been issued or that any  proceedings for that
purpose  are  pending  before,  or  threatened  by, the SEC and the  Registrable
Securities  are  available  for  resale  under  the  1933  Act  pursuant  to the
Registration Statement.

                                    Very truly yours,

                                    [   ]


                                    By:_________________________________________







                                  Exhibit 4.4

THE  WARRANT  REPRESENTED  BY THIS  CERTIFICATE  AND THE  SHARES  ISSUABLE  UPON
EXERCISE  HEREOF HAVE NOT BEEN  REGISTERED  UNDER THE SECURITIES ACT OF 1933, AS
AMENDED,  ANY STATE SECURITIES LAWS OR ANY OTHER SECURITIES LAWS. THE SECURITIES
HAVE BEEN  ACQUIRED  FOR  INVESTMENT  AND MAY NOT BE  OFFERED  FOR  SALE,  SOLD,
TRANSFERRED  OR  ASSIGNED  IN  THE  ABSENCE  OF (I)  AN  EFFECTIVE  REGISTRATION
STATEMENT FOR THE SECURITIES  UNDER THE SECURITIES ACT OF 1933, AS AMENDED,  AND
THE RECEIPT OF ALL NECESSARY  STATE AND FOREIGN  APPROVALS OR (II) AN OPINION OF
COUNSEL,  IN FORM AND SUBSTANCE  REASONABLY  ACCEPTABLE TO ALTAIR  INTERNATIONAL
INC., THAT  REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR ANY APPLICABLE  STATE
OR FOREIGN SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID ACT.

                        THE TRANSFER OF THIS WARRANT IS
                        RESTRICTED AS DESCRIBED HEREIN.

                           ALTAIR INTERNATIONAL INC.
           (INCORPORATED UNDER THE LAWS OF THE PROVINCE OF ONTARIO)

                  Warrant for the Purchase of Common Shares,
                                 no par value


                   THIS WARRANT EXPIRES ON DECEMBER 29, 1999


No. __                                                        _________ Shares

         THIS CERTIFIES that, for value received, ______________ with an address
at _____________________________________________________________________________
(including  any  transferee,  the  "Holder"),  is entitled to subscribe  for and
purchase from Altair International Inc., an Ontario corporation (the "Company"),
upon the terms and conditions set forth herein, at any time or from time to time
before 5:00 P.M. on December 29, 1999,  New York time (the  "Exercise  Period"),
______ of the Company's Common Shares, no par value ("Common Stock"), at a price
equal to $16.7188,  which  represents 125% of the closing price per share of the
Common Stock on the Nasdaq  SmallCap Market or the Nasdaq  National  Market,  as
applicable,  on the date  immediately  prior to the date of issuance hereof (the
"Exercise Price").

         This  Warrant  is the  warrant  or one of the  warrants  (collectively,
including any warrants issued upon the exercise or transfer of any such warrants
in whole or in part, the "Warrants") issued pursuant to the Securities  Purchase
Agreement (the "Securities Purchase Agreement") by and among the Company and the
purchasers of the original issue of the Warrants,  pursuant to which the Company
has  agreed to issue and sell its 5%  Convertible  Subordinated  Debentures  due
December 29, 2001 (the  "Debentures")  and warrants to purchase shares of Common
Stock.  As used  herein the term "this  Warrant"  shall  mean and  include  this
Warrant and any Warrant or Warrants  hereafter  issued as a  consequence  of the
exercise or transfer of this Warrant in whole or in part.

         The number of shares of Common  Stock  issuable  upon  exercise  of the
Warrants (the "Warrant Shares") and the Exercise Price may be adjusted from time
to time as hereinafter set forth.

         1. This Warrant may be exercised during the Exercise Period,  as to the
whole or any lesser  number of whole  Warrant  Shares  equal to or greater  than
25,000  Warrant  Shares,  by the surrender of this Warrant (with the election at
the  end  hereof  duly  executed)  to  the  Company  at  its  office  at  Altair
International Inc., 1725 Sheridan Avenue,  Suite 140, Cody, Wyoming 82414, or at
such other  place as is  designated  in writing by the  Company.  Such  executed
election must be accompanied by payment in an amount equal to the Exercise Price
multiplied  by the  number of Warrant  Shares  for which  this  Warrant is being
exercised. Such payment may be made by certified or bank cashier's check payable
to the order of the Company.

Exhibit 4.4


         2. Upon each exercise of the Holder's rights to purchase Warrant Shares
and the  Company's  receipt of the full amount of the Exercise  Price payable in
connection  therewith,  the Holder shall be deemed to be the holder of record of
the  Warrant  Shares  issuable  upon  such  exercise,  notwithstanding  that the
transfer books of the Company shall then be closed or certificates  representing
such Warrant  Shares shall not then have been actually  delivered to the Holder.
As soon as reasonably  practicable after each such exercise of this Warrant, the
Company shall issue and deliver to the Holder a certificate or certificates  for
the Warrant Shares  issuable upon such  exercise,  registered in the name of the
Holder or its designee.  If this Warrant  should be exercised in part only,  the
Company  shall,  upon  surrender of this Warrant for  cancellation,  execute and
deliver a new Warrant evidencing the right of the Holder to purchase the balance
of the Warrant Shares (or portions thereof) subject to purchase hereunder.

         3. (a) Any  Warrants  issued  upon the  transfer or exercise in part of
this Warrant shall be numbered and shall be registered in a Warrant  Register as
they are issued. The Company shall be entitled to treat the registered holder of
any  Warrant  on the  Warrant  Register  as the  owner in fact  thereof  for all
purposes and shall not be bound to recognize  any equitable or other claim to or
interest  in such  Warrant  on the part of any  other  person,  and shall not be
liable for any  registration  or transfer of Warrants which are registered or to
be  registered  in the name of a fiduciary or the nominee of a fiduciary  unless
made with the actual  knowledge  that a  fiduciary  or nominee is  committing  a
breach of trust in requesting such registration or transfer,  or with the actual
knowledge  of such facts that its  participation  therein  amounts to bad faith.
This Warrant  shall be  transferable  only (i) in  increments  with respect to a
number of Warrant Shares equal to or greater than 25,000 Warrant Shares and (ii)
on the books of the Company upon delivery thereof duly endorsed by the Holder or
by its duly  authorized  attorney or  representative,  or  accompanied by proper
evidence of succession,  assignment,  or authority to transfer.  In all cases of
transfer  by an  attorney,  executor,  administrator,  guardian,  or other legal
representative,  duly  authenticated  evidence of his or its authority  shall be
produced.  Upon any  registration  of transfer,  the Company shall deliver a new
Warrant  or  Warrants  to the  person  entitled  thereto.  This  Warrant  may be
exchanged,  at the option of the Holder thereof,  for another Warrant,  or other
Warrants  of  different  denominations,  of like tenor and  representing  in the
aggregate  the right to  purchase a like number of Warrant  Shares (or  portions
thereof),   upon  surrender  to  the  Company  or  its  duly  authorized  agent.
Notwithstanding  the  foregoing,  the Company  shall have no obligation to cause
Warrants  to be  transferred  on its books to any person  if, in the  opinion of
counsel to the Company, such transfer does not comply with the provisions of the
Securities  Act of 1933, as amended (the "Act"),  and the rules and  regulations
thereunder.  Upon receipt by the Company of evidence reasonably  satisfactory to
it of the loss, theft,  destruction or mutilation of a Warrant,  and, in case of
loss, theft or destruction,  of indemnity or security reasonably satisfactory to
it and  reimbursement  to the  Company  of all  reasonable  expenses  incidental
thereto,  and upon surrender and  cancellation of the Warrant if mutilated,  the
Company  will make and  deliver a new  Warrant of like  tenor to the  registered
owner in lieu of the Warrant so lost, stolen, destroyed or mutilated.

            (b) The Holder  acknowledges that it has been advised by the Company
that neither this Warrant nor the Warrant Shares have been registered  under the
Act, that this Warrant is being or has been issued and the Warrant Shares may be
issued on the basis of the statutory  exemption  provided by Section 4(2) of the
Act or Regulation D promulgated thereunder, or both, relating to transactions by
an issuer not involving  any public  offering,  and that the Company's  reliance
thereon is based in part upon the representations made by the original Holder in
the Securities  Purchase  Agreement.  The Holder  acknowledges  that he has been
informed by the Company of, or is  otherwise  familiar  with,  the nature of the


                                   - 2 -



<PAGE>


Exhibit 4.4

limitations  imposed by the Act and the rules and regulations  thereunder on the
transfer  of  securities.  In  particular,  the  Holder  agrees  that  no  sale,
assignment  or transfer  of this  Warrant or the Warrant  Shares  issuable  upon
exercise  hereof  shall be valid or  effective,  and the  Company  shall  not be
required to give any effect to any such sale, assignment or transfer, unless (i)
the sale,  assignment  or transfer  of this  Warrant or such  Warrant  Shares is
registered under the Act, it being understood that neither this Warrant nor such
Warrant  Shares are  currently  registered  for sale and that the Company has no
obligation  or  intention to so register  this  Warrant or such  Warrant  Shares
except as  specifically  provided in the  Registration  Rights  Agreement by and
among the Company and the purchasers of the original  issue of the Warrants,  or
(ii) this Warrant or such Warrant  Shares are sold,  assigned or  transferred in
accordance with all the  requirements and limitations of Rule 144 under the Act,
it being  understood  that Rule 144 is not available at the time of the original
issuance of this Warrant for the sale of this Warrant or such Warrant Shares and
that  there can be no  assurance  that Rule 144 sales will be  available  at any
subsequent time, or (iii) such sale,  assignment or transfer is otherwise exempt
from registration under the Act.

            (c) Following any  assignment  or other  transfer  permitted by this
Warrant and the  Securities  Purchase  Agreement that results in the issuance of
warrants to  purchase  Warrant  Shares  purchasable  hereunder  to more than one
person or  entity,  all  elections  that may be made by the  Holders  under such
warrants  shall be made by  written  notice of  Holders  representing  rights to
purchase a majority  of the  Warrant  Shares  for which such  warrants  are then
exercisable.

         4. The Company shall at all times reserve and keep available out of its
authorized  and unissued  Common Stock,  solely for the purpose of providing for
the exercise of the rights to purchase all Warrant  Shares  granted  pursuant to
the Warrants, such number of shares of Common Stock as shall, from time to time,
be sufficient  therefor.  The Company  covenants that all shares of Common Stock
issuable upon exercise of this Warrant,  upon receipt by the Company of the full
Exercise Price therefor, shall be validly issued, fully paid, nonassessable, and
free of  preemptive  rights.  The Company  shall  provide for and  maintain  the
listing of the Common  Stock,  including  the  Warrant  Shares,  upon the Nasdaq
SmallCap  Market or the Nasdaq  National  Market,  as  applicable  (or any other
securities  exchange  or  automated  quotation  system  which  is the  principal
exchange or system on which the Common Stock is then traded or listed).

         5.  (a) In case the  Company  shall at any  time  after  the date  this
Warrant is first issued (i) declare a dividend on the  outstanding  Common Stock
payable  in  shares of Common  Stock or in  rights to  acquire  shares of Common
Stock,  (ii)  subdivide  the  outstanding  Common  Stock,  or (iii)  combine the
outstanding  Common Stock into a smaller  number of shares,  then,  in each such
case,  the  Exercise  Price,  and the number of  Warrant  Shares  issuable  upon
exercise  of this  Warrant,  in effect at the time of the  record  date for such
dividend or of the effective date of such  subdivision or combination,  shall be
proportionately adjusted so that the Holder after such time shall be entitled to
receive the aggregate number and kind of shares for such consideration which, if
such  Warrant  had  been  exercised  immediately  prior  to  such  time  at  the
then-current  exercise  price,  he would have owned upon such  exercise and been
entitled to receive by virtue of such dividend, subdivision or combination. Such
adjustment  shall be made  successively  whenever  any event  listed above shall
occur.

            (b) In case the  Company  shall  issue or fix a record  date for the
issuance  to all  holders of Common  Stock of rights,  options,  or  warrants to
subscribe  for or  purchase  Common  Stock (or  securities  convertible  into or
exchangeable  for Common  Stock) at a price per share (or having a conversion or


                                   - 3 -



<PAGE>


Exhibit 4.4

exchange price per share, if a security  convertible  into or  exchangeable  for
Common Stock) less than the lesser of the Exercise  Price or the Current  Market
Price per share of Common Stock on such record  date,  then,  in each case,  the
Exercise  Price shall be adjusted by  multiplying  the Exercise  Price in effect
immediately  prior to such  record date by a fraction,  the  numerator  of which
shall be the number of shares of Common  Stock  outstanding  on such record date
plus the number of shares of Common Stock which the aggregate  offering price of
the total  number of shares of Common  Stock so to be offered (or the  aggregate
initial  conversion  or  exchange  price  of  the  convertible  or  exchangeable
securities so to be offered)  would  purchase at such Exercise  Price or Current
Market Price, as applicable, and the denominator of which shall be the number of
shares  of Common  Stock  outstanding  on such  record  date plus the  number of
additional shares of Common Stock to be offered for subscription or purchase (or
into which the  convertible  or  exchangeable  securities  so to be offered  are
initially  convertible  or  exchangeable);   provided,  however,  that  no  such
adjustment  pursuant  to this  Section  5(b) shall be made  which  results in an
increase in the Exercise Price.  Such adjustment  shall become  effective at the
close of business on such record date;  provided,  however,  that, to the extent
the shares of Common Stock (or securities  convertible  into or exchangeable for
shares of Common Stock) are not delivered,  or if securities convertible into or
exchangeable for shares of Common Stock are delivered but are not converted into
or exchanged for shares of Common Stock,  the Exercise Price shall be readjusted
after the expiration of such rights, options, or warrants (but only with respect
to Warrants exercised after such expiration),  to the Exercise Price which would
then be in effect had the  adjustments  made upon the  issuance of such  rights,
options,  or warrants been made upon the basis of delivery of only the number of
shares of Common  Stock (or  securities  convertible  into or  exchangeable  for
shares of Common Stock) actually issued.  In case any subscription  price may be
paid in a consideration part or all of which shall be in a form other than cash,
the value of such  consideration  shall be as  determined  in good  faith by the
board of directors  of the  Company,  whose  determination  shall be  conclusive
absent manifest  error.  Shares of Common Stock owned by or held for the account
of the Company or any majority-owned  subsidiary shall not be deemed outstanding
for the purpose of any such computation.

            (c) For the  purpose  of any  computation  under  this  Section 5 or
Section 1, the Current  Market Price per share of Common Stock on any date shall
be deemed to be the average of the daily closing  prices of the Common Stock for
the 10 consecutive trading days immediately preceding the date in question.  The
closing  price  for  each  day  shall  be the  closing  price  on the  principal
securities exchange (including,  for purposes hereof, the Nasdaq SmallCap Market
or the Nasdaq  National  Market,  as  applicable)  on which the Common  Stock is
listed or admitted to trading or, if the Common  Stock is not listed or admitted
to trading on any securities  exchange,  the highest  reported bid price for the
Common Stock as furnished by the National  Association  of  Securities  Dealers,
Inc.  through Nasdaq or a similar  organization if Nasdaq is no longer reporting
such information. If on any such date the Common Stock is not listed or admitted
to trading on any securities exchange and is not quoted by Nasdaq or any similar
organization,  the fair  value  of a share of  Common  Stock  on such  date,  as
determined  in good  faith  by the  board of  directors  of the  Company,  whose
determination shall be conclusive absent manifest error, shall be used.

            (d) No  adjustment  in the Exercise  Price shall be required if such
adjustment is less than $.05; provided,  however,  that any adjustments which by
reason of this  Section 5 are not  required to be made shall be carried  forward
and taken into account in any subsequent adjustment. All calculations under this
Section 5 shall be made to the nearest cent or to the nearest  one-thousandth of
a share,  as the case may be (with 0.005 being  rounded to 0.01 and 0.0005 being
rounded to 0.001).

                                   - 4 -

Exhibit 4.4


            (e) In any  case in  which  this  Section  5 shall  require  that an
adjustment  in the  Exercise  Price be made  effective as of a record date for a
specified  event,  the Company may elect to defer,  until the occurrence of such
event,  issuing to the Holder,  if the Holder  exercised this Warrant after such
record date,  the shares of Common  Stock,  if any,  issuable upon such exercise
over and above the shares of Common Stock,  if any,  issuable upon such exercise
on the basis of the Exercise Price in effect prior to such adjustment; provided,
however,  that  the  Company  shall  deliver  to the  Holder a due bill or other
appropriate  instrument evidencing the Holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.

            (f) Upon each  adjustment  of the Exercise  Price as a result of the
calculations made in Section 5(b) hereof, this Warrant shall thereafter evidence
the right to purchase,  at the adjusted  Exercise  Price,  that number of shares
(calculated  to the nearest  thousandth)  obtained  by dividing  (A) the product
obtained by multiplying the number of shares  purchasable  upon exercise of this
Warrant  prior to  adjustment  of the number of shares by the Exercise  Price in
effect prior to  adjustment of the Exercise  Price by (B) the Exercise  Price in
effect after such adjustment of the Exercise Price.

            (g)  Whenever  there  shall be an  adjustment  as  provided  in this
Section 5, the Company shall promptly cause written notice thereof to be sent by
certified  mail,  postage  prepaid,  to the  Holder,  at its address as it shall
appear  in the  Warrant  Register,  which  notice  shall  be  accompanied  by an
officer's  certificate  setting forth the number of Warrant  Shares  purchasable
upon the exercise of this Warrant and the Exercise  Price after such  adjustment
and setting forth a brief  statement of the facts  requiring such adjustment and
the  computation  thereof,  which  officer's  certificate  shall  be  conclusive
evidence of the correctness of any such adjustment absent manifest error.

            (h) The Company shall not be required to issue a fraction of a share
of Common Stock or other  capital stock of the Company upon the exercise of this
Warrant.  If any  fraction of a share would be issuable on the  exercise of this
Warrant (or  specified  portions  thereof),  the  Company  shall  purchase  such
fraction for an amount in cash equal to the same fraction of the Current  Market
Price of such share of Common Stock on the date of exercise of this Warrant.

         6. (a) In case of any  consolidation  of the Company with, or merger of
the  Company  with  or  into,  another  corporation  (other  than  a  merger  or
consolidation in which the Company is the surviving or continuing  corporation),
or in case of any  sale,  lease or  conveyance  to  another  corporation  of the
property and assets of any nature of the Company as an entirety or substantially
as an entirety, such successor,  leasing or purchasing corporation,  as the case
may be, shall (i) execute and deliver to the Holder an agreement  providing that
the Holder  shall have the right  thereafter  to receive  upon  exercise of this
Warrant  solely  the kind and  amount of  shares of stock and other  securities,
property,  cash or any combination  thereof receivable upon such  consolidation,
merger,  sale, lease or conveyance by a holder of the number of shares of Common
Stock for which this Warrant might have been exercised immediately prior to such
consolidation,  merger,  sale,  lease or  conveyance,  and (ii)  make  effective
provision in its certificate of  incorporation  or otherwise,  if necessary,  to
effect such agreement.  Such agreement shall provide for adjustments which shall
be as nearly equivalent as practicable to the adjustments in Section 5.

Exhibit 4.4

            (b) In case of any  reclassification  or  change  of the  shares  of
Common Stock  issuable upon exercise of this Warrant (other than a change in par
value or from no par  value  to a  specified  par  value,  or as a  result  of a
subdivision or  combination,  but including any change in the shares into two or
more classes or series of shares),  or in case of any consolidation or merger of
another  corporation  into the  Company in which the  Company is the  continuing
corporation  and in which there is a  reclassification  or change  (including  a
change to the right to receive shares of stock (other than Common Stock),  other
securities, property or cash) of the shares of Common Stock (other than a change
in par value, or from no par value to a specified par value, or as a result of a
subdivision or  combination,  but including any change in the shares into two or
more classes or series of shares), the Holder shall have the right thereafter to
receive upon  exercise of this  Warrant  solely the kind and amount of shares of

FOR IMMEDIATE RELEASE: December 30, 1997

                   ALTAIR COMPLETES $10 MILLION CONVERTIBLE
             DEBT FINANCING OFFERED THROUGH PRUDENTIAL SECURITIES

CODY, WY -- Altair International Inc. (NASDAQ:ALTIF/ASE:AIL) today announced the
closing of a $10  million  convertible  debt  financing.  Under the terms of the
financing,  funding  will be made in two blocks - $5 million at closing with the
additional $5 million available  between eight and ten months after closing,  at
Altair's option. Financing was provided by an institutional investor. Prudential
Securities  Incorporated  acted as  placement  agent and  financial  advisor  to
Altair.

"This financing gives Altair  increased  financial  strength to proceed with our
Tennessee  property and bring the  centrifugal  jig to market," said Dr. William
Long, Altair's President.

The debt  conversion  price is  determined  by using a formula based on Altair's
stock price at the time of conversion.  The convertible debt accrues interest at
5%,  payable in cash or common  stock.  The  investors  also  received  two year
warrants to purchase up to 150,000 shares of the company's  common stock at 125%
of the  common  stock  price on the day  prior  to  closing.  Altair  will fie a
registration  statement for the necessary  shares of common stock underlying the
convertible  debt and  warrants.  Final  documentation  will be  filed  with the
Alberta Stock Exchange.

Prudential  Securities  Incorporated is a fully  diversified,  global securities
firm based in New York City,  serving  clients in the U.S. and overseas  through
approximately 6,000 Financial Advisors. The fifth-largest  brokerage firm in the
U.S.,  Prudential Securities is a subsidiary of the Prudential Insurance Company
of America.

Altair  International  is  in  the  development  stage  of  commercializing  its
state-of-the-art technology, the Centrifugal Jig, which recovers extremely fine,
heavy particulate matter using a combination of a mechanical jig and centrifugal
force. Potential  applications include gold/mineral recovery,  coal cleaning and
environmental  remediation.  Altair is the 100% owner of a large titanium/zircon
mineral deposit in Tennessee.
