                             CONVERSION OF DEBENTURE

         SECTION 3.1 Conversion; Conversion Price; Valuation Event.

         (a)  Subject  to  the  filing  of a  certificate  of  amendment  to the
certificate of incorporation of the Company,  at the option of the Holder,  this
Debenture may be converted, either in whole or in part, up to the full Principal
Amount hereof (in  increments of $1,000 in Principal  Amount) into Common Shares
(calculated as to each such  conversion to the nearest  1/100th of a share),  at
any time and from time to time on any Business Day,  subject to compliance  with
Section  3.2.  The number of Common  Shares  into which  this  Debenture  may be
converted  is  equal to the  dollar  amount  of the  Debenture  being  converted
multiplied by eleven,  minus the product of the Conversion  Price  multiplied by
ten times the dollar amount of the  Debenture  being  converted,  and the entire
foregoing  result shall be divided by the  Conversion  Price.  In addition,  the
Company shall pay to the Holder on the Conversion Date, in cash, any accrued and
unpaid  interest on the Debenture  being converted not included at the option of
the Holder in clause (i) of the immediately preceding sentence.  The "Conversion
Price" shall be equal to the lesser of (i) $0.20,  or (ii) eighty  percent (80%)
of the average of the 3 lowest Volume Weighted  Average Prices during the twenty
(20)  Trading   Days  prior  to  Holder's   election  to  convert  (a  "Discount
Multiplier");  provided,  that in the event the  Registration  Statement has not
been  declared  effective  by the SEC by the  Deadline  or, if the  Registration
Statement  has  theretofore  been  declared  effective  but  is  not  thereafter
effective,  then the  applicable  Discount  Multiplier  shall  decrease by three
percentage  points  (3%) for each month or  partial  month  occurring  after the
Deadline that the Registration Statement is not effective.

Beginning in the first full calendar month after the  Registration  Statement is
declared  effective,  Holder shall  convert at least 5% of the face value of the
Debenture per calendar  month into Common  Shares of the Company,  provided that
the Common  Shares are  available,  registered  and freely  tradable.  If Holder
converts more than 5% of the face value of the Debenture in any calendar  month,
the excess over 5% shall be credited against the next month's minimum conversion
amount. In the event Holder does not convert at least 5% of the Debenture in any
particular  calendar month,  Holder shall not be entitled to collect interest on
the Debenture for that month.

If the Holder elects to convert a portion of the Debenture  and, on the day that
the election is made,  the Volume  Weighted  Average  Price is below $0.05,  the
Company shall have the right to prepay that portion of the Debenture that Holder
elected  to  convert,  plus any  accrued  and unpaid  interest,  at 150% of such
amount.  In the event  that the  Company  elects to prepay  that  portion of the
Debenture, Holder shall have the right to withdraw its Conversion Notice.

<PAGE>

         (b)  Notwithstanding the provisions of Section 3.1(a), in the event the
Company's Registration Statement has not been declared effective by the Deadline
or, if the Registration Statement has theretofore been declared effective but is
not  thereafter  effective,  the  following  will also apply in  addition to any
damages incurred by the Holder as a result thereof:

              (i) The Holder  may  demand  repayment  of one  hundred  and fifty
percent  (150%) of the  Principal  Amount of the  Debenture,  together  with all
accrued and unpaid interest thereon, in cash, at any time prior to the Company's
Registration  Statement being declared effective by the SEC or during the period
that the Company's Registration Statement is not effective, such repayment to be
made  within  three (3)  business  days of such  demand.  In the event  that the
Debenture  is so  accelerated,  in addition to the  repayment of one hundred and
fifty percent (150%) of the Principal  Amount together with accrued  interest as
aforesaid,  the Company shall  immediately issue and pay, as the case may be, to
the Holder  50,000  Shares of Common  Stock and $15,000 for each thirty (30) day
period,  or  portion  thereof,  during  which the  Principal  Amount,  including
interest thereon, remains unpaid, with the monthly payment amount to increase to
$20,000 for each thirty (30) day  period,  or portion  thereof,  after the first
ninety (90) day period;

              (ii) If the Holder does not elect to accelerate the Debenture, the
Company  shall  immediately  issue or pay, as the case may be, to Holder  50,000
Shares of Common  Stock and $15,000 for each thirty (30) day period,  or portion
thereof,  that the  Registration  Statement is not  effective,  with the monthly
payment  amount to increase  to $20,000  for each  thirty  (30) day  period,  or
portion thereof, after the first ninety (90) day period.

              (iii)  If  the  SEC  indicates  that  the  Company's  Registration
Statement  will be  declared  effective  upon  request by the  Company,  and the
Company does not, within 3 business days of the SEC indication, request that the
Registration  Statement become  effective,  the amounts set forth in subsections
(ii) and (iii) above shall double.

         SECTION 3.2 Exercise of Conversion  Privilege.  (a)  Conversion of this
Debenture may be exercised on any Business Day by the Holder by  telecopying  an
executed and completed  Conversion  Notice to the Company.  Each date on which a
Conversion Notice is telecopied to the Company in accordance with the provisions
of this  Section 3.2 shall  constitute  a  Conversion  Date.  The Company  shall
convert this  Debenture  and issue the Common Stock Issued at  Conversion in the
manner  provided  below in this  Section  3.2,  and all voting and other  rights
associated  with  the  beneficial  ownership  of  the  Common  Stock  Issued  at

the time specified in the Conversion  Notice.  The Conversion  Notice also shall
state the name or names  (with  addresses)  of the persons who are to become the
holders  of the  Common  Stock  Issued at  Conversion  in  connection  with such
conversion.  As promptly  as  practicable  after the  receipt of the  Conversion
Notice as  aforesaid,  but in any event not more than  three (3)  Business  Days
after the Company's  receipt of such  Conversion  Notice,  the Company shall (i)
issue the Common Stock Issued at Conversion in accordance with the provisions of
this Article 3 and (ii) cause to be mailed for delivery by overnight courier, or

<PAGE>

Common Share  deliverable  upon such conversion and (z) cash or shares of Common
Stock, as applicable,  representing the amount of accrued and unpaid interest on
this Debenture as of the Conversion  Date.  Such  conversion  shall be deemed to
have been effected at the time at which the Conversion Notice indicates,  and at
such time the rights of the Holder of this Debenture,  as such (except if and to
the extent that any Principal Amount thereof remains  unconverted),  shall cease
and the Person and  Persons  in whose name or names the Common  Stock  Issued at
Conversion  shall be  issuable  shall be deemed  to have  become  the  holder or
holders of record of the Common Shares represented  thereby,  and all voting and
other rights  associated  with the  beneficial  ownership of such Common  Shares
shall at such time vest with such Person or Persons. The Conversion Notice shall
constitute  a contract  between the Holder and the  Company,  whereby the Holder
shall be deemed to  subscribe  for the number of Common  Shares which it will be
entitled to receive upon such  conversion  and, in payment and  satisfaction  of
such  subscription (and for any cash adjustment to which it is entitled pursuant
to Section 3.4), to surrender this Debenture and to release the Company from all
liability thereon (except if and to the extent that any Principal Amount thereof
remains  unconverted).  No cash  payment  aggregating  less than $1.00  shall be
required to be given unless specifically requested by the Holder.

                 (b) If, at any time after the date of this  Debenture,  (i) the
Company challenges,  disputes or denies the right of the Holder hereof to effect
the conversion of this  Debenture  into Common Shares or otherwise  dishonors or
rejects any Conversion  Notice  delivered in accordance with this Section 3.2 or
(ii) any third  party who is not and has never been an  Affiliate  of the Holder
commences any lawsuit or legal proceeding or otherwise  asserts any claim before
any court or public or governmental  authority  which seeks to challenge,  deny,
enjoin, limit, modify, delay or dispute the right of the Holder hereof to effect
the conversion of this Debenture into Common Shares,  then the Holder shall have
the right, by written notice to the Company,  to require the Company to promptly
redeem this  Debenture for cash at one hundred and fifty (150%) of the Principal
Amount  thereof,  together with all accrued and unpaid  interest  thereon to the
date of redemption.  Under any of the circumstances set forth above, the Company
shall be  responsible  for the payment of all costs and  expenses of the Holder,
including reasonable legal fees and expenses,  as and when incurred in defending
itself in any such action or pursuing its rights  hereunder  (in addition to any
other rights of the Holder).

                 (c) The Holder  shall be entitled to  exercise  its  conversion
privilege  notwithstanding  the  commencement  of any case under the  Bankruptcy
Code.  In the event the  Company  is a debtor  under the  Bankruptcy  Code,  the
Company  hereby waives to the fullest  extent  permitted any rights to relief it
may  have  under  11  U.S.C.  ss.  362 in  respect  of the  Holder's  conversion
privilege.  The Company hereby waives to the fullest extent permitted any rights

U.S.C. ss. 362.

         SECTION 3.3  Fractional  Shares.  No fractional  Common Shares or scrip
representing fractional Common Shares shall be delivered upon conversion of this
Debenture.  Instead of any  fractional  Common Shares which  otherwise  would be
delivered  upon  conversion  of this  Debenture,  the  Company  shall pay a cash
adjustment  in respect of such  fraction in an amount equal to the same fraction
multiplied by the Current Market Price on the Conversion Date. No

<PAGE>

cash  payment  of  less  than  $1.00  shall  be  required  to  be  given  unless
specifically requested by the Holder.

         SECTION 3.4 Adjustments.  The Conversion Price and the number of shares
deliverable  upon  conversion of this  Debenture are subject to adjustment  from

in or  distribution  with  respect to the Common  Stock of the  Company),  sell,
convey,  transfer or otherwise dispose of all or substantially all its property,
assets or business to another  Person,  or effectuate a transaction or series of
related  transactions in which more than fifty percent (50%) of the voting power

pursuant to the terms of such  Fundamental  Corporate  Change,  shares of common
stock of the successor or acquiring corporation, or any cash, shares of stock or
other  securities or property of any nature  whatsoever  (including  warrants or
other subscription or purchase rights) in addition to or in lieu of common stock
of the successor or acquiring  corporation ("Other Property") are to be received
by or distributed to the holders of Common Stock of the Company, then the Holder
of this Debenture shall have the right  thereafter,  at its sole option,  to (x)
require the Company to prepay this  Debenture  for cash at one hundred and fifty
percent (150%) of the Principal  Amount  thereof,  together with all accrued and
unpaid  interest  thereon to the date of  prepayment,  (y) receive the number of
shares of common  stock of the  successor  or  acquiring  corporation  or of the
Company, if it is the surviving corporation, and Other Property as is receivable
upon or as a result  of such  Fundamental  Corporate  Change  by a holder of the
number of shares of Common  Stock  into  which the  outstanding  portion of this
Debenture may be converted at the Conversion Price applicable  immediately prior
to such  Fundamental  Corporate  Change  or (z)  require  the  Company,  or such
successor,  resulting or purchasing corporation, as the case may be, to, without
benefit of any  additional  consideration  therefor,  execute and deliver to the
Holder a  debenture  with  substantial  identical  rights,  privileges,  powers,
restrictions  and other terms as this Debenture in an amount equal to the amount
outstanding under this Debenture immediately prior to such Fundamental Corporate
Change.  For  purposes  hereof,  "common  stock of the  successor  or  acquiring
corporation"  shall include stock of such  corporation of any class which is not
preferred  as to  dividends  or  assets  over any  other  class of stock of such
corporation  and which is not subject to  prepayment  and shall also include any
evidences  of  indebtedness,  shares  of  stock or other  securities  which  are
convertible into or exchangeable for any such stock,  either immediately or upon
the arrival of a specified  date or the  happening of a specified  event and any
warrants  or other  rights to  subscribe  for or purchase  any such  stock.  The
foregoing provisions shall similarly apply to successive  Fundamental  Corporate
Changes.

         SECTION 3.5 Certain Conversion Limits.

         Notwithstanding  anything herein to the contrary,  if and to the extent
that, on any date, the holding by the Holder of this  Debenture  would result in
the Holder's  being deemed the  beneficial  owner of more than 4.99% of the then
Outstanding  shares of Common  Stock,  then the Holder shall not have the right,
and the Company  shall not have the  obligation,  to convert any portion of this
Debenture as shall cause such Holder to be deemed the  beneficial  owner of more
than 4.99%

<PAGE>

of the then  Outstanding  shares of  Common  Stock.  If any  court of  competent
jurisdiction  shall  determine  that the foregoing  limitation is ineffective to
prevent a Holder from being  deemed the  beneficial  owner of more than 4.99% of
the then Outstanding  shares of Common Stock, then the Company shall prepay such
portion  of this  Debenture  as shall  cause  such  Holder  not to be deemed the
beneficial  owner of more than  4.99% of the then  Outstanding  shares of Common
Stock. Upon such determination by a court of competent jurisdiction,  the Holder
shall have no interest in or rights under such portion of the Debenture. Any and
all interest paid on or prior to the date of such determination  shall be deemed
interest paid on the  remaining  portion of this  Debenture  held by the Holder.
Such prepayment shall be for cash at a prepayment price of one hundred and fifty
percent (150%) of the Principal  Amount  thereof,  together with all accrued and
unpaid interest thereon to the date of prepayment.

         SECTION  3.6  Surrender  of  Debentures.  Upon any  redemption  of this

Section  2.4, the Holder  shall  either  deliver  this  Debenture by hand to the
Company at its principal  executive offices or surrender the same to the Company
at such  address by  nationally  recognized  overnight  courier.  Payment of the
redemption  price or the amount due on maturity  specified in Section 2.4, shall
be made by the  Company to the Holder  against  receipt  of this  Debenture  (as
provided in this Section 3.5) by wire transfer of immediately available funds to
such account(s) as the Holder shall specify by written notice to the Company. If
payment of such redemption  price is not made in full by the redemption date, or
the amount due on maturity is not paid in full by the Maturity  Date, the Holder
shall again have the right to convert  this  Debenture  as provided in Article 3
hereof or to declare an Event of Default.

the SEC.

         SECTION  5.2 Notice of Default.  If any one or more events  occur which

that the  Company  obtains  any  other  financing  (either  debt,  equity,  or a
combination thereof) which is to close during the term of this Debenture, Holder
shall be  entitled  to a right of first  refusal  to enable  it to, at  Holder's
option,  either:  (i)  match  the  terms  of the  other  financing,  or (ii) add
additional  principal to this Debenture,  in the amount of such other financing,

Event of  Default  occurs  and is  continuing,  then and in every  such case the
Holder  may,  by a notice in writing to the  Company,  rescind  any  outstanding

declaration this Debenture shall become immediately due and payable in cash at a
price of one hundred and fifty percent (150%) of the Principal  Amount  thereof,

the contrary, if at any time the applicable interest rate as provided for herein
shall exceed the maximum lawful rate which may be contracted for, charged, taken
or received by the Holder in accordance  with any  applicable  law (the "Maximum

Company  hereby waives and agrees not to allege or claim that any  provisions of
this Note could give rise to or result in any actual or  potential  violation of
any applicable usury laws.

         SECTION  6.5  Remedies  Not  Waived.  No course of dealing  between the
Company and the Holder or any delay in  exercising  any rights  hereunder  shall
operate as a waiver by the Holder.

         SECTION 6.6 Remedies.  The Company  acknowledges that a breach by it of
its  obligations  hereunder  will  cause  irreparable  harm  to the  Holder,  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 Debenture will be inadequate and agrees, in the event of
a  breach  or  threatened  breach  by the  Company  of the  provisions  of  this
Debenture,  that the Holder shall be entitled to all other available remedies at
law or in equity,  and in addition to the  penalties  assessable  herein,  to an
injunction or injunctions  restraining,  preventing or curing any breach of this
Debenture and to enforce specifically the terms and provisions thereof,  without
the necessity of showing  economic  loss and without any bond or other  security
being required.

         SECTION  6.7  Payment of Certain  Amounts.  Whenever  pursuant  to this
Debenture  the Company is  required to pay an amount in excess of the  Principal
Amount plus accrued and unpaid  interest,  the Company and the Holder agree that
the  actual  damages  to the Holder  from the  receipt  of cash  payment on this
Debenture  may be  difficult  to  determine  and the amount to be so paid by the
Company  represents  stipulated  damages  and not a penalty  and is  intended to
compensate  the  Holder  in part for loss of the  opportunity  to  convert  this
Debenture and to earn a

<PAGE>

return from the sale of shares of Common Stock acquired upon  conversion of this
Debenture  at a price in excess of that price paid for such  shares  pursuant to
this  Debenture.  The  Company and the Holder  hereby  agree that such amount of
stipulated  damages is not  disproportionate  to the possible loss to the Holder
from the receipt of a cash  payment  without  the  opportunity  to convert  this
Debenture into shares of Common Stock.

sale transfer, dissolution, liquidation or winding-up.

         SECTION 7.2 Register.  The Company shall keep at its principal office a

La Jolla Cove Investors, Inc. ("Holder").

         1.1 Warrants. The Company hereby grants to Holder the right to purchase
3,000,000 shares of the Company's Common Stock (the "Shares" or "Warrant Shares.
For  avoidance  of doubt,  this Warrant may be  exercised  concurrently  with or

referred to as the  "Conversion  Date."  Defined terms not defined  herein shall

that the Common Shares are available,  registered and freely tradable. If Holder
exercises more than 5% of the Warrants in any calendar month, the excess over 5%
shall be credited against the next month's minimum exercise amount. In the event
Holder does not exercise at least 5% of the Warrants in any particular  calendar
month,  Holder shall not be entitled to collect  interest on the  Debenture  for
that month.

This  Warrant  shall  expire and Holder  shall no longer be able to purchase the

                                    ARTICLE 2
                                    EXERCISE

         2.1 Method of Exercise.  Holder may exercise this Warrant by delivering
a duly executed Warrant Notice of Exercise in substantially the form attached as
Appendix 1 to the principal office of the Company.

         2.2 Delivery of Certificate and New Warrant. As promptly as practicable
after the receipt of the Warrant  Notice of Exercise,  but in any event not more
than three (3) Business Days after the Company's  receipt of the Warrant  Notice
of  Exercise,  the  Company  shall  issue the  Shares and cause to be mailed for
delivery by  overnight  courier,  or if a  Registration  Statement  covering the
Shares  has  been  declared  effective  by the SEC  cause  to be  electronically
transferred,  to Holder a certificate  representing  the Shares acquired and, if
this Warrant has not been fully  exercised  and has not  expired,  a new Warrant
substantially in the form of this Warrant  representing the right to acquire the
portion of the Shares not so acquired.

         2.3  Replacement  of  Warrants.   On  receipt  of  evidence  reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this Warrant and, in the case of loss,  theft or destruction,  on delivery of an
indemnity  agreement  reasonably  satisfactory in form and amount to the Company
or, in the case of mutilation,  or surrender and  cancellation  of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

         2.4 Exercise Price. The Exercise Price of this Warrant shall $1.00.

         2.5  Cashless  Exercise.   Notwithstanding  anything  to  the  contrary
contained in this Warrant,  if the resale of the Warrant Shares by Holder is not
then  registered  pursuant  to an  effective  Registration  Statement,  upon the
expiration  of one year from the Issue Date,  this  Warrant may be  exercised by
presentation  and  surrender  of this  Warrant to the  Company at its  principal
executive  offices  with a written  notice  of  Holder's  intention  to effect a
cashless  exercise,  including a  calculation  of the number of shares of Common
Stock to be issued upon such  exercise in  accordance  with the terms hereof ( a
"Cashless Exercise"). In the event of a Cashless Exercise, in lieu of paying the
Exercise Price in cash,  Holder shall  surrender this Warrant for that number of
shares of Common Stock determined by multiplying the number of Warrant Shares to
which it otherwise would be entitled by a fraction, the numerator of which shall
be the difference  between the then current Market Price per share of the Common
Stock and the Exercise  Price,  and the  denominator  or which shall be the then
current Market Price per share of Common Stock.

                                   ARTICLE 3
                            ADJUSTMENT TO THE SHARES

         The number of Shares  purchasable upon the exercise of this Warrant and
the  Exercise  Price shall be subject to  adjustment  form time to time upon the
occurrence of certain events, as follows:

<PAGE>

         3.1  Reclassification.  In case of any  reclassification  or  change of
outstanding securities of the class issuable upon exercise of this Warrant then,
and in any such case, the Holder, upon the exercise hereof at any time after the
consummation of such reclassification or change, shall be entitled to receive in
lieu of each Share theretofore  issuable upon exercise of this Warrant, the kind
and amount of shares of stock, other securities,  money and/or property received
upon such reclassification or change by a holder of one Share. The provisions of
this  Section  2.1 shall  similarly  apply to  successive  reclassifications  or
changes.

         3.2  Subdivision or  Combination of Shares.  If the Company at any time
while this Warrant remains  outstanding and unexpired shall subdivide or combine
its Shares, the Exercise Price shall be proportionately decreased in the case of
a subdivision or increased in the case of a combination.

         3.3 Stock Dividends.  If the Company, at any time while this Warrant is
outstanding  shall pay a dividend with respect to its Shares  payable in Shares,
or make any other  distribution  of Shares  with  respect to Shares  (except any
distribution  specifically  provided  for in Section 2.1 and Section 2.2 above),
then the Exercise Price shall be adjusted,  effective from and after the date of
determination   of   shareholders   entitled  to  received   such   dividend  or
distribution,  to that price  determined by  multiplying  the Exercise  Price in
effect  immediately  prior to such date of determination by a fraction,  (a) the
numerator of which shall be the total number of Shares  outstanding  immediately
prior to such dividend or  distribution,  and (b) the denominator of which shall
be the total number of Shares  outstanding  immediately  after such  dividend or
distribution.

         3.4 Non-Cash  Dividends.  If the Company at any time while this Warrant
is outstanding shall pay a dividend with respect to Shares payable in securities
other than Shares or other non-cash property,  or make any other distribution of
such  securities  or property  with respect to Shares  (except any  distribution
specifically  provided  for in Section 2.1 and  Section  2.2  above),  then this
Warrant shall  represent the right to acquire upon exercise of this Warrant such
securities  or  property  which a holder of Shares  would have been  entitled to
receive upon such dividend or distribution, without the payment by the Holder of
any additional consideration for such securities or property.

         3.5 Effect of Reorganization and Asset Sales. If any (i) reorganization
or  reclassification  of the Common  Stock (ii)  consolidation  or merger of the
Company with or into another corporation,  or (iii) sale or all or substantially
all of the  Company's  operating  assets to another  corporation  followed  by a
liquidation of the Company (any such transaction  shall be referred to herein as
an "Event"), is effected in such a way that holders of common Stock are entitled
to receive securities and/or assets as a result of their Common Stock ownership,
the Holder,  upon  exercise of this  Warrant,  shall be entitled to receive such
shares of stock securities or assets which the Holder would have received had it
fully  exercised  this  Warrant on or prior the record date for such Event.  The
Company shall not merge into or consolidate with another corporation or sell all
of its assets to another corporation for a consideration consisting primarily of
securities of such corporation,  unless the successor or acquiring  corporation,
as the case may be, shall expressly  assume the due and punctual  observance and
performance  of each and every  covenant  and  condition  of this  Warrant to be
performed or observed by the Company and all of the  obligations and liabilities
hereunder,  subject to such  modification  as shall be  necessary to provide for
adjustments   which  shall  be  as  nearly  equivalent  as  practicable  to  the
adjustments  provided  for in this  Section 2. The  foregoing  provisions  shall
similarly apply to successive mergers, consolidations or sales of assets.

<PAGE>

         3.6  Adjustment  of  Number of  Shares.  Upon  each  adjustment  in the
Exercise  Price,  the number of Shares shall be adjusted,  to the nearest  whole
share, to the product obtained by multiplying the number of Shares,  purchasable
immediately prior to such adjustment by a fraction, the numerator of which shall
be the Exercise Price  immediately  prior to such adjustment and the denominator
of which shall be the Exercise Price immediately thereafter.

         3.7 No Impairment.  The Company shall not, by amendment of its articles
of incorporation or through a 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 under this Warrant by the Company,  but shall at all times
in good faith assist in carrying out all of the  provisions  of this Warrant and
in taking all such  action as may be  reasonably  necessary  or  appropriate  to
protect Holder's rights hereunder against  impairment.  If the Company takes any
action  affecting its Common Stock other than as described  above that adversely
affects Holder's rights under this Warrant, the Exercise Price shall be adjusted
downward and the number of Shares  issuable  upon exercise of this Warrant shall
be adjusted  upward in such a manner that the aggregate  Exercise  Price of this
Warrant is unchanged.

         3.8 Fractional  Shares. No fractional Shares shall be issuable upon the
exercise of this Warrant, and the number of Shares to be issued shall be rounded
down to the nearest whole Share.

         3.9 Certificate as to Adjustments.  Upon any adjustment of the Exercise
Price,  the Company,  at its expense,  shall compute such adjustment and furnish
Holder with a  certificate  of its Chief  Financial  Officer  setting forth such
adjustment and the facts upon which such adjustment is based. The Company shall,
upon written  request,  furnish Holder a certificate  setting forth the Exercise
Price in effect upon the date thereof and the series of  adjustments  leading to
such Exercise Price.

         3.10 No Rights of Shareholders. This Warrant does not entitle Holder to
any voting rights or any other rights as a  shareholder  of the Company prior to
the exercise of Holder's right to purchase Shares as provided herein.

                                   ARTICLE 4

                  REPRESENTATIONS AND COVENANTS OF THE COMPANY

         4.1 Representations  and Warranties.  The Company hereby represents and
warrants to Holder that all Shares  which may be issued upon the exercise of the
purchase  right  represented  by this Warrant,  shall,  upon  issuance,  be duly
authorized,  validly issued, fully paid and nonasessable,  and free of any liens
and encumbrances.

<PAGE>

         4.2 Notice of Certain Events.  If the company  proposes at any time (a)
to declare any dividend or distribution upon its Common Stock,  whether in cash,
property, stock, or other securities and whether or not a regular cash dividend;
(b) to offer for  subscription pro rata to the holders of any class or series of
its stock any additional shares of stock of any class or series or other rights;
(c) to effect any  reclassification  or recapitalization of Common Stock; (d) to

license,  or convey all or  substantially  all of its assets,  or to  liquidate,
dissolve or wind up; or (e) offer holders of registration rights the opportunity
to participate in an underwritten  public  offering of the Company's  securities
for cash,  then,  in  connection  with each such event,  the Company  shall give
Holder (1) at least 20 days prior  written  notice of the date on which a record
will be taken for such  dividend,  distribution,  or  subscription  rights  (and
specifying  the date on which the  holders  of  Common  Stock  will be  entitled
thereto) or for  determining  rights to vote,  if any, in respect of the matters
referred to in (c) and (d) above;  (2) in the case of the matters referred to in
(c) and (d)  above at least 20 days  prior  written  notice of the date when the
same will take place  (and  specifying  the date on which the  holders of Common
Stock will be entitled to exchange  their Common Stock for  securities  or other
property  deliverable upon the occurrence of such event); and (3) in the case of
the matter referred to in (e) above,  the same notice as is given to the holders
of such registration rights.

         4.3 Information Rights. So long as Holder holds this Warrant and/or any
of the Shares,  the company shall deliver to Holder (a) promptly  after mailing,
copies of all notices or other written communications to the shareholders of the
Company,  (b) within ninety (90) days of their availability,  the annual audited
financial  statements of the Company certified by independent public accountants
of recognized  standing,  and (c) within  forty-five  (45) days after the end of
each fiscal  quarter or each fiscal year,  the  Company's  quarterly,  unaudited
financial statements.

         4.4  Reservation  of  Warrant  Shares.  Subject  to  the  filing  of  a
certificate of amendment to the certificate of incorporation of the Company, the
Company has reserved and will keep available, out of the authorized and unissued
shares of Common Stock, the full number of shares  sufficient to provide for the
exercise of the rights of purchase represented by this Warrant.

         4.5 Registration Rights. If Holder exercises this Warrant and purchases
some or all of the Shares,  Holder shall have the Registration  Rights set forth
in that certain Registration Rights Agreement executed concurrently therewith.

                                   ARTICLE 5

                   REPRESENTATIONS AND COVENANTS OF THE HOLDER

         5.1 Private Issue. Holder understands (i) that the Shares issuable upon
exercise of Holder's  rights  contained in the Warrant are not registered  under
the Act or qualified under  applicable  state securities laws on the ground that
the issuance  contemplated  by the Warrant will be exempt from the  registration
and qualifications requirements thereof, and (ii) that the Company's reliance on
such  exemption  is  predicated  on Holder's  representations  set forth in this
Article 5.

<PAGE>

         5.2  Financial  Risk.  Holder  has such  knowledge  and  experience  in
financial  and business  matters as to be capable of  evaluating  the merits and
risks of its  investment  and has the ability to bear the economic  risks of its
investment.

         5.3 Risk of No  Registration.  Holder  understands  that if the Company
does not  register  with the  Securities  and  Exchange  Commission  pursuant to
Section  12 of the Act,  or file  reports  pursuant  to  Section  15(d),  of the
Securities Exchange Act of 1934 (the "1934 Act"), or if a registration statement
covering the  securities  under the Act is not in effect when it desires to sell
(i) the right to purchase  Shares  pursuant to the  Warrant,  or (ii) the Shares
issuable upon exercise of the right to purchase, it may be required to hold such
securities for an indefinite period.

         5.4 Accredited  Investor.  Holder is an "accredited  investor," as such
term is defined in Regulation D promulgated pursuant to the Act. ARTICLE 6

be  transferred  or  assigned  in  whole  or in  part  without  compliance  with
applicable  federal  and  state  securities  laws  by  the  transferor  and  the
transferee   (including,   without   limitation,   the  delivery  of  investment
representation  letters  and  legal  opinions  reasonably  satisfactory  to  the
Company, as reasonably requested by the Company).  The Company shall not require
Holder to provide an opinion of counsel if the  transfer is to an  affiliate  of
Holder.

         6.3 Transfer Procedure. Holder shall have the right without the consent
of the Company to  transfer  or assign in whole or in part this  Warrant and the
Shares  issuable upon exercise of this Warrant.  Holder agrees that unless there
is in effect a  registration  statement  under  the Act  covering  the  proposed
transfer of all or part of this Warrant, prior to any such proposed transfer the
Holder shall give written notice  thereof to the Company (a "Transfer  Notice").
Each Transfer Notice shall describe the manner and circumstances of the proposed
transfer  in  reasonable  detail  and,  if the  company  so  requests,  shall be
accompanied by an opinion of legal counsel, in a form reasonably satisfactory to
the Company,  to the effect that the proposed  transfer may be effected  without
registration  under the Act; provided that the Company will not require opinions
of counsel for  transactions  involving  transfers to  affiliates or pursuant to
Rule 144  promulgated by the Securities and Exchange  Commission  under the act,
except in unusual circumstances.

obligations  hereunder will cause  irreparable harm to the Holder,  by vitiating
the intent and  purpose of the  transactions  hereby.  Accordingly,  the Company
acknowledges  that the remedy at law for a breach of its obligations  under this
Warrant will be  inadequate  and agrees,  in the event of a breach or threatened
breach by the Company of the  provisions of this Warrant,  that the Holder shall
be entitled,  in addition to all other  available  remedies at law or in equity,
and  in  addition  to the  penalties  assessable  herein,  to an  injunction  or
