of the  outstanding  Common Stock,  the  applicable  Conversion  Price in effect
immediately prior to the stock split shall be proportionately  decreased. If the
Company shall at any time or from time to time after the Issuance Date,  combine

Any  adjustments  under this Section  4(c)(i) shall be effective at the close of
business on the date the stock split or combination occurs.

         (ii)  Adjustments  for  Certain  Dividends  and  Distributions.  If the
Company shall at any time or from time after the Issuance Date, make or issue or
set a record date for the  determination  of holders of Common Stock entitled to
receive a dividend  or other  distribution  payable  in shares of Common  Stock,
then, and in each event, the applicable  Conversion Price in effect  immediately
prior to such event shall be  decreased  as of the time of such  issuance or, in
the event such a record date shall have been fixed,  as of the close of business
on such record date, by multiplying,  as applicable,  the applicable  Conversion
Price then in effect by a fraction;

                  (A) the numerator of which shall be the total number of shares
of Common Stock  issued and  outstanding  immediately  prior to the time of such
issuance or the close of business on such record date; and

shall at any time or from time to time after the Issuance Date, make or issue or

receive a dividend or other distribution  payable in other than shares of Common
Stock, then, and in each event, an appropriate  revision to the Conversion Price
shall be made and  provision  shall be made (by  adjustments  of the  Conversion
Price  or  otherwise)  so that  the  holder  of this  Note  shall  receive  upon
conversions  thereof,  in  addition  to the  number of  shares  of Common  Stock
receivable  thereon,  the number of  securities  of the Company which they would
have received had this Note been converted into Common Stock on the date of such
event and had  thereafter,  during the period from the date of such event to and
including the  Conversion  Date,  retained such  securities  (together  with any
distributions  payable  thereon during such period),  giving  application to all
adjustments  called for during such period  under this  Section  4(c)(iii)  with
respect to the rights of the holders of the Note.

         (iv) Adjustments for Reclassification, Exchange or Substitution. If the

exchange,  substitution  or  otherwise  (other  than by way of a stock  split or
combination of shares or stock dividends provided for in Sections 4(c)(i),  (ii)
and  (iii),  or a  reorganization,  merger,  consolidation,  or sale  of  assets
provided  for in Section  4(c)(v)),  then,  and in each  event,  an  appropriate
revision to the Conversion  Price shall by made and provisions shall be made (by
adjustments  of the  Conversion  Price of  otherwise) so that the holder of this
Note shall  have the right  thereafter  to  convert  such Note into the kind and
amount of shares of stock and other securities receivable upon reclassification,
exchange,  substitution  or other change,  by holders of the number of shares of
Common Stock into which such Note might have been converted immediately prior to
such  reclassification,  exchange,  substitution or other change, all subject to
further adjustment as provided herein.

         (v) Adjustments for Reorganization,  Merger,  Consolidation or Sales of
Assets. If at any time or from time to time after the  Issuance Date there shall
be a capital reorganization of the Company

(other than by way of a stock split or combination of shares or stock  dividends
or  distributions  provided  for  in  Section  4(c)(i),  (ii)  and  (iii),  or a
reclassification,  exchange or  substitution  of shares  provided for in Section
4(c)(iv)),  or a merger or  consolidation  of the Company  with or into  another
corporation, or the sale of all or substantially all of the Company's properties
or assets to any other person,  then as a part of such  reorganization,  merger,
consolidation, or sale, an appropriate revision to the Conversion Price shall be
made and provision  shall be made (by  adjustments  of the  Conversion  Price or
otherwise)  so that the holder of this Note shall have the right  thereafter  to
convert  this  Note  into the kind and  amount  of  shares  of stock  and  other
securities  or property of the Company or any  successor  corporation  resulting
from such reorganization,  merger, consolidation,  or sale, to which a holder of
Common Stock deliverable upon conversion of such shares would have been entitled
upon such reorganization,  merger, consolidation,  or sale, to which a holder of
Common Stock deliverable upon conversion of such shares would have been entitled
upon such  reorganization,  merger,  consolidation,  or sale.  In any such case,
appropriate  adjustment  shall be made in the  application  of the provisions of
this  Section  4(c)(v)  with  respect to the rights of the  holders of this Note
after the  reorganization,  merger,  consolidation,  or sale to the end that the
provisions of this Section  4(c)(v)  (including any adjustment in the applicable
Conversion  Ratio  then in  effect  and the  number  of shares of stock or other
securities deliverable upon conversion of this Note) shall be applied after that
event in as nearly an equivalent manner as may be practicable.

d) No  Impediment.  The Company  shall not, by amendment of its  Certificate  of
Incorporation or through any reorganization,  transfer of assets, consolidation,
merger, dissolution,  issue or sale of securities or any other voluntary action,
avoid or seek to avoid the  observance or  performance of any of the terms to be
observed or performed  hereunder  by the Company,  but will at all times in good
faith, assist in the carrying out of all the provisions of this Section 4 and in
the taking of all such action as may be  necessary  or  Appropriate  in order to
protect the Conversion Rights of the holders of the Note against impairment.

readjustment  of the  Conversion  Price or number  of  shares  of  Common  Stock
issuable upon conversion of the Note pursuant to this Section 4,

the  Company  at  its  expense  shall  promptly   compute  such   adjustment  or
readjustment  in  accordance  with the terms  hereof and furnish  notice to each
holder  of  such  Note,  a  certificate   setting  forth  such   adjustment  and
readjustment,  showing  in detail  the  facts  upon  which  such  adjustment  or
readjustment is based. The Company shall,  upon written request of the holder of
this Note,  at any time,  furnish or cause to be furnished to such holder a like
certificate  setting forth such  adjustments and  readjustments,  the applicable
Conversion  Price in effect at the time and the number of shares of Common Stock
and the amount,  if any, of other securities or property which at the time would
be received upon the conversion of such Note. Notwithstanding the foregoing, the
Company shall not be obligated to deliver a certificate  unless such certificate
would  reflect an increase or decrease of at least one percent of such  adjusted
amount.

f) Issue  Taxes.  The  Company  shall pay any and all  issue  and  other  taxes,
excluding  federal,  state or local income taxes, that may be payable in respect
of any issue or delivery of shares of Common  Stock on  conversion  of this Note

pay any transfer taxes  resulting  from any transfer  requested by any holder in
connection with any such conversion.

g)  Notices  and  Delivery  of  Shares.  All  notices  and other  communications
hereunder shall be in writing and shall be deemed given (i) on the same date, if
delivered  personally  or by facsimile by not later than 7:00 p.m. New York time

certificates evidencing Note surrendered for conversion, certificates evidencing
all shares of Common Stock into which this Note shall be converted.

h) Fractional  Shares. No fractional shares of Common Stock shall be issued upon
conversion  of the Note.  In lieu of any  fractional  shares to which the holder
would otherwise be entitled, the Company shall pay

cash equal to the product of such fraction multiplied by the Conversion Price of
one share of the Company's Common Stock on the applicable Conversion Date.

i) Reservation of Common Stock.  The Company shall at all times reserve and keep
available,  out of its authorized but unused shares of Common Stock,  solely for
the purpose of effecting the  conversion of the Note,  the full number of shares
deliverable upon conversion of all the Note from time to time  outstanding.  The
Company  shall,  from  time to time in  accordance  with  the  Colorado  General
Corporations Law, as amended, increase the authorized number of shares of Common
Stock if at any  time the  unused  number  of  authorized  shares  shall  not be
sufficient to permit the conversion of all of the Note at the time  outstanding.
In such connection, the Company shall hold a special meeting of stockholders for
the purpose of authorizing  additional shares of Common Stork not later than 120
days  after any date in which the  Company  shall  have  insufficient  shares of
Common Stock so reserved.

effected on the  applicable  Conversion  Date.  The  converting  holder shall be
deemed  to have  become a  stockholder  of  record  of the  Common  Stock on the
applicable  Conversion Date. Upon conversion of only a portion of this Note, the
Company  shall issue and  deliver to such holder at the expense of the  Company,
against receipt of the original note delivered for partial  cancellation,  a new
Note representing the unconverted portion of this Note so surrendered.

k)       Regulatory Compliance.

conversion of this Note require  registration or listing with or approval of any
government authority,  stock exchange or other regulatory body under any federal
or state law or regulation or otherwise before such shares may be validly issued
or delivered upon  conversion,  the Company shall, at its sole cost and expense,
in good  faith  and as  expeditiously  as  possible,  endeavor  to  secure  such
registration, listing or approval, as the case may be.

         (ii) The shares of Common Stock  issuable  upon the election to convert
shall be Rule 144 restricted shares (the "Restricted

Securities").  After  issuance  of the  Shares,  Company  agrees to use its best
efforts to assist holder in registering the Restricted Securities or to register
the Restricted Securities under the Act subject to the rules,  regulations,  and
other provisions of said Act.

         (iii) In the event the  holder  elects to  convert  into  ownership  of
shares of the Company  Stock,  at the time of such  conversation,  the holder of
such shares shall have the following piggyback rights with reference:

                  (A) At any time that the  Company  proposes  to file a Company
registration  statement on Form S-1, including the pending Form S-1 registration
filed on January 8, 1998,  under the Act (the  "Registrations  Statement"),  the
Company shall cause to be included in such registration statement any securities
issued or subject to issuance in this transaction;  provided,  however, that if,
at any time  after  giving  written  notice of its  intention  to  register  any
securities and prior to the effective date of the Company Registration Statement
filed in connection with such registration,  the Company shall determine for any
reason  not  to  register  or  to  delay  registration  of  holder's  Restricted
Securities,  the  Company  may, at its  election,  give  written  notice of such
determination to holder and, thereupon:

                           (1) in the ease of a determination not to register,
shall be relieved of its obligation to register holder's  Restricted  Securities
in connection  with such  registration  (but not from its  obligation to pay the
registration expenses in connection therewith), and

                           (2) in the case of a delay in registering, shall be
permitted  to delay  registering  holder's  Restricted  Securities  for the same
period as the delay in registering such other securities.

                  (B) The Company's obligation to include Restricted  Securities
in a Company's  Registration Statement pursuant to Section 7(a) shall be subject
to the following limitations:

                           (1) The Company may elect, at its sole option and for
any reason, not to register holder's Restricted Shares,  provided however,  that
this right is limited to one (1) time and relative to

one (1) particular Company Registration Statement.

                           (2) The Company shall not be obligated to include any
Restricted Securities in a registration statement filed on Form S-4, Form S-8 or
such other similar successor forms then in effect under the Securities Act.

                           (3) If a Company Registration Statement involves an
underwritten  offering  and the  managing  underwriter  advises  the  Company in
writing that in its opinion,  the number of securities  requested to be included
in such Company  Registration  Statement exceeds the number which can be sold in
such  offering  without  adversely  affecting  the  offering,  the Company shall
include in such Company  Registration  Statement  the number of such  securities
which the Company is so advised can be sold in such offering  without  adversely
affecting the offering, determined as follows:

                               (i) first, the securities proposed by the Company
to be sold for it own account, and

                               (ii) second, any Restricted Securities  requested
to be included in such  registration  and any other securities of the Company in
accordance with the  priorities,  if and then existing among the holders of such
securities pro rata among the holders thereof  requesting  such  registration on
the basis of the number of shares of such securities requested to be included by
such holders.

                           (4) The  Company  shall  not  be obligated to include
Restricted Securities in more than one (1) Company Registration Statement.

                  (C) To the extent holder's Restricted  Securities are intended
to be included in a Company  Registration  Statement,  holder may include any of
its Restricted  Securities in such Company  Registration  Statement  pursuant to
this  Agreement only if holder  furnishes to the Company in writing,  within ten
(10) business days after receipt of a written request therefor, such information
specified in Item 507 of Regulation S-K under the Act or such other  information
as the Company may  reasonably  request for use in  connection  with the Company
Registration  Statement or Prospectus or preliminary Prospectus included therein
and in any application to the NASD. Holder as to which the Company  Registration
Statement  is being  effected  agrees to furnish  promptly  to the  Company  all
information

required to be disclosed in order to make all information  previously  furnished
to the Company by holder not materially misleading.

l) Limitations on Amount of Conversion.  Notwithstanding  anything  contained in
this Note to the  contrary,  in no event shall any holder of Note be entitled or
required to convert  this Note in excess of that number of shares of Note which,
upon  giving  effect to such  conversion,  would cause the  aggregate  number of
shares of Common Stock  beneficially  owned by the holder and its  affiliates to
exceed 4.9% of the outstanding  shares of the Company's Common Stock immediately
following such conversion.  For purposes of the foregoing proviso, the aggregate
number of  shares  of Common  Stock  beneficially  owned by the  holder  and its
affiliates  shall  include the number of shares of Common  Stock  issuable  upon
conversion of this Note with respect to which the  determination of such proviso
is being  made,  but shall  exclude  the number of shares of Common  Stock which
would be  issuable  upon  (i)  conversion  of the  remaining,  unconverted  Note
beneficially  owned by such  holder and its  affiliates,  and (ii)  exercise  or
conversion of the unexercised or unconverted  portion of any other securities of
the Company  (including  without limitation any warrants) which are beneficially
owned by the holder and its  affiliates and which are subject to a limitation on
conversion or exercise analogous to the limitation  contained herein.  Except as
set forth in the preceding sentence, for purposes of this paragraph,  beneficial
ownership shall be calculated in accordance with Section 13(d) of the Securities
Exchange  Act of 1934,  as amended.  Any holder of Note may waive the  foregoing
limitations  set forth in this  paragraph by written  notice to the Company upon
not less than 30 days prior notice (with such waiver taking effect only upon the
expiration of such 30-day notice period).

9. SUBORDINATION TO SENIOR DEBT.

a) Payment of the principal of and interest on this Note is subordinated, to the
extent  and  in  the  manner  provided  herein,  to  the  prior  payment  of all
indebtedness of the Company and/or all  Subsidiaries  of the Company,  for money
borrowed  or  other   obligations   which  is  now  or  may  hereafter  be  owed
(collectively,  "Senior Debt") to any bank, commercial finance company,  factor,
insurance company or other  institution the lending  activities are regulated by
law (individually, a "Senior Lender" and collectively,  "Senior Lenders"), which
may,  hereafter on any one or more occasions provide financing to the Company or
any of its Subsidiaries, secured by liens on any of the assets and properties of
the Company and/or any of its Subsidiaries  (individually and  collectively,  an
"Institutional Borrower").

b) Upon any payment or distribution of assets or securities of the Institutional
Borrower,  as the  case  may be,  of any  kind or  character,  whether  in cash,
property or securities,  upon any  dissolution or winding up or total or partial
liquidation or reorganization of the Institutional  Borrower,  whether voluntary
or involuntary or in bankruptcy, insolvency,  receivership or other proceedings,
all amounts  payable  under Senior Debt shall first be paid in full in cash,  or
payment provided for in cash or cash equivalents, before the holder hereof shall
be entitled to receive  any  payment on account of  principal  of or interest on
this Note. Before any payment may be made by the  Institutional  Borrower of the
principal of or interest on this

Note upon any such  dissolution or winding up or liquidation or  reorganization,
any  payment  or  distribution  of assets  or  securities  of the  Institutional
Borrower of any kind of character,  whether in cash, property or securities,  to
which the holder  hereof would be entitled,  except for the  provisions  of this
Section  9,  shall be made by the  Institutional  Borrower  or by any  receiver,
trustee in bankruptcy,  liquidating  trustee,  agent or other person making such
payment  or  distribution,  directly  to the  holders  of  Senior  Debt or their
representatives  to the extent  necessary  to pay all such  Senior  Debt in full
after giving effect to any concurrent  payment or distribution to the holders of
such Senior Debt.

c) Upon the  happening of any default in payment of the principal of or interest
on any Senior Debt, then, unless and until such default shall have been cured or
waived or shall have  ceased to exist,  no direct or  indirect  payment in cash,
property or securities,  by set-off or otherwise,  shall be made or agreed to be
made by the Institutional Borrower on account of the principal of or interest on
this Note.

d) Upon the  happening  of an event of default  (other than under  circumstances
when the terms of Section 9(c) above are applicable)  with respect to any Senior
Debt  pursuant to which the holder  thereof is entitled  under the terms of such
Senior Debt to accelerate the maturity thereof,  and upon written notice thereof
given to each of the Institutional  Borrower and the holder of this Note by such
holder of Senior Debt ("Payment  Notice"),  then, unless and until such event of
default shall have been cured or waived or shall have ceased to exist, no action
shall or may be taken for  collection  of any  amounts  under this Note,  and no
direct or  indirect  payment  in cash,  property  or  securities,  by set-off or
otherwise,  shall be made or agreed to be made by the Institutional  Borrower an
account of the  principal of or interest on this Note until such Senior Debt has
been paid in full accordance with its terms.

e) In the event than,  notwithstanding  the  provisions  of this  Section 9, any
payment shall be made on account of the principal of or interest on this Note in
contravention  of such  provisions,  then  such  payment  shall  be held for the
benefit of, and shall be paid over and  delivered to, the holders of such Senior
Debt remaining unpaid to the

extent necessary to pay in fall in cash or cash equivalents the principal of and
interest on such Senior Debt in accordance with its terms after giving effect to
any concurrent payment or distribution to the holders of such Senior Debt.

f)       Nothing contained in this Section 9 shall

         (i) impair the conversion rights of the holder hereof referred to
in Section 4 above,

         (ii)  impair,  as between the Company and the holder of this Note,  the
obligation of the Company,  which is absolute and  unconditional,  to pay to the
holder  hereof  principal and interest as the same shall become due and payable,
or (iii)  prevent the holder  hereof  from  exercising  all  rights,  powers and
remedies  otherwise  provided  herein or by  applicable  law, all subject to the
express limitations provided herein.

g) Upon the occurrence of an Event of Default,  if any Senior Debt shall then be
outstanding,  no  acceleration  of the  maturity of this Note shall be effective
until the earlier of (i) ten (10) days shall have passed  following  the date of
delivery to the  Institutional  Borrower by a Senior Lender(s) of written notice
of acceleration of any Senior Debt, or (ii) the maturity of any then outstanding
Senior  Debt  shall have been  accelerated  by reason of a default  hereon.  The
Company may pay the holder  hereof any  defaulted  payment and all other amounts
due following any such acceleration of the maturity of this Note if this Section
9 would not prohibit such payment to be made at that time.

h) Upon  payment  in full of all  Senior  Debt,  the Payee of this Note shall be
subrogated  to the rights of the holder or holders of Senior Debt to receive all
payments or  distributions  applicable on Senior Debt to the extent of the prior
application  thereto of moneys or other assets which would have been received in
respect  of this  Note,  but  for  these  subordination  provisions,  until  the
principal of, and interest on, this Note shall have been paid in full.

i)       The Payee, by accepting this Note

         (i) shall be bound by all of the foregoing subordination
provisions;

         (ii) agrees expressly for the benefit of the present and future holders
of  Senior  Debt  that  this  Note is  subject  to the  foregoing  subordination
provisions;  (iii) authorizes such persons as shall be designated by all holders
of Senior Debt at any given  time,  on his or its benefit to execute and deliver
such agreements, assignments, proofs of claim and other documents appropriate to
effectuate the foregoing subordination provisions;  and (iv) hereby appoints the
person so designated his or its attorney-in-fact for such purpose.

j) The  foregoing  subordination  provisions  shall  be for the  benefit  of all
holders of Senior Debt from time to time  outstanding,  and each of such holders
may proceed to enforce such provisions either directly against the holder hereof
or in any other manner provided by law.

k)  Notwithstanding  anything to the  contrary  set forth in this Section 9, the
security interest of the holder of this Note (as specified in Section 10 hereof)
is subject and subordinated  only to the prior first lien and security  interest
of any  holder  of  Senior  Debt  of the  Company,  unless  otherwise  expressly
consented to in writing by the Payee.

10. PERMITTED PAYMENTS.

Notwithstanding  the  provisions of Section 9 of this Note, and provided that no
default or event of default (or event which,  with the passage of time or giving
of notice  or both)  has  occurred,  will  occur as a result  of the  "Permitted
Payment" (herein  defined),  or will occur with the passage of time or giving of
notice or both,  under any document or instrument  evidencing  such Senior Debt,
the Company may pay to the Payee, and the Payee may accept from the Company, the
principal  payments of, and/or interest  payments on, the outstanding  principal
amount of this  Note  when due on an  unaccelerated  basis  (herein,  "Permitted
Payments");  it being  understood and agreed by the Payee by accepting this Note
that neither:

a) the payment terms set forth in Section l of this Note;

b) the subordination provisions contained in Section 9 of this Note,
nor

c) the provisions of this Section 10 of this Note, may be modified or
amended without the prior written consent of each and every holder of
