         Progressive Telecommunications Corporation, a Nevada corporation (the

Clearwater, Florida 33755, for value received, hereby promises to pay the
registered holder hereof (the "Holder") the principal sum set forth above on
December 1, 2001 (the "Maturity Date"), in such coin or currency of the United
States of America as at the time of payment shall be the legal tender for the
payment of public and private debts, and to pay interest, less any amounts
required by law to be deducted or withheld, computed on the basis of a 360-day
year, on the unpaid principal balance hereof from the date hereof (the
"Original Issue Date"), at the rate of 9% per year, until such principal sum
shall have become due and payable, or has been converted by the Holder pursuant
to Section 5, below. Interest payments will be made in such number of shares of
the Company's common stock, $.001 par value ("Common Stock"), computed in
accordance with Section 5.1 below and shall be paid semi-annually commencing
June 15, 2000, or if the principal of the debenture is earlier converted, upon
conversion pursuant to Section 5, below. All references herein to dollar
amounts refers to U.S. dollars.

         By acceptance and purchase of this Debenture, the registered holder
hereof agrees with the Company that the Debenture shall be subject to the
following terms and conditions:

         1. Authorization of Debentures. The Company has authorized the issue
and sale of its 9% Convertible Subordinated Debentures due December 1, 2001
(the "Debentures," such term includes any debentures which may be issued in
exchange or in replacement thereof) in the aggregate principal amount of not
more than U.S. $3,000,000, issued in multiples of $50,000 in principal amount.

         2. Warrants. For each one dollar and fifty cents ($1.50) invested, the
Company shall issue the Holder one (1) Common Stock Purchase Warrant (up to
2,000,000). Each Warrant shall be exercisable for a period of three years from
the date of issuance at the rate of $1.50 per share.

         3. Transfer or Exchange. Prior to due presentation to the Company for
transfer of this Debenture, the Company and any agent of the Company may treat
the person in whose name this Debenture is duly registered on the Company's
Debenture Register as the owner hereof for the purpose of receiving payment as
herein provided and for all other purposes. Neither the Debenture nor the
shares issuable upon conversion hereof may not be offered, sold, pledged or
otherwise transferred unless and until registered under the Securities Act of
1933, as amended (the "Act") or unless the Company has received an opinion of
counsel acceptable to it that such registration is not required.

         4. Current Market Price:

            4.1 For purposes of this Debenture, "Current Market Price" of the
Common stock means:

            (a) If traded on a securities exchange or the NASDAQ National
                Market, the closing price of the Common Stock on such exchange;
                or

            (b) If traded over the counter, the high closing bid price reported
                by Bloomberg from the NASDAQ the Small Cap Market OTC Bulletin
                Board or pink sheets (as the case may be);

         In all other events, the market price determined by the Board of
directors of the Company in good faith.

         5. Conversion of Debentures.

            5.1 Right to Convert the Debenture: The record holder of this
Debenture shall be entitled, on or after the Date of Original Issuance, at the
option of the Holder, to convert this Debenture, in whole or in part, into the
number of fully-paid and non-assessable shares of Common Stock determined by
dividing the amount or principal or interest to be converted by $1.50
("Conversion Price").

            5.2 Exercise of Conversion Privilege. In order to exercise the
conversion privilege, the Holder shall surrender such Debenture, together with
the Notice of Conversion annexed hereto as Exhibit 1 appropriately endorsed to
the Company at its principal office, accompanied by written notice to the
Company (a) stating that the Holder elects to convert the Debenture or a
portion thereof, and if a portion, the amount of such portion in multiples of
$1,000 in principal amount, and (b) setting forth the name or names (with
address) in which the certificate or certificates for shares of Common Stock
issuable upon such conversion shall be issued. Provided the Debenture is
received properly endorsed promptly by the Company, the date of conversion of
such Debenture shall be deemed to be the date of receipt of Notice of
Conversion, even if the Company's stock transfer books are at that time closed,
and the converting Holder shall be deemed to have become, on the date of
conversion, the record holder of the shares of Common Stock deliverable upon
such conversion. If the Debenture is not received, properly endorsed by the
fifth business day following the date the Company receives

                                       2
<PAGE>   3

Notice of Conversion, the date of conversion shall be deemed to be the date the
Debenture is received, provided that such later receipt will not lower the
Conversion Price stated in the Notice of Conversion.

         Within five business days after the date of conversion, the Company
shall issue and deliver to such converting Holder a certificate or certificates
for the number of shares of Common Stock due on such conversion. No adjustments
in respect of interest or cash dividends shall be made upon the conversion of
any Debenture or Debentures.

         Upon conversion of the Debenture in part, the Company shall execute
and deliver to the Holder thereof, at the expense of the Company, a new
Debenture, in aggregate principal amount equal to the unconverted portion of
such Debenture. Such new Debenture shall have the same terms and provisions
other than the principal amount as the Debenture or Debentures surrendered for
conversion.

            5.3 Duration of Conversion Privilege. The right to subscribe for
and purchase shares of Common Stock pursuant to the Conversion privilege
granted herein shall commence on the Original Issue Date and shall expire at
5:00 p.m., New York time on December 1, 2001.

            5.4 Stock Fully Paid; Not Restricted. The Company convenants and
agrees that:

            (a) all shares which may be issued upon the exercise of the
                conversion privilege granted herein will, upon issuance in
                accordance with the terms hereof, be fully paid, nonassessable,
                and free from all taxes, liens and charges (except for taxes,
                if any, upon the income of the Holder) with respect to the
                issue thereof, and that the issuance thereof shall not give
                rise to any preemptive rights on the part of the stockholders;
                and

            (b) all shares issued after the effective date of the Registration
                Statement (defined below) which will be issued upon the
                conversion privilege granted herein will be free of all
                restrictions under the Securities Act of 1933; and will not
                bear any legends or be the subject of any stop transfer
                restrictions;

            5.5 Antidilution Provisions. The following provisions apply to the
Debenture:

            (a) In case the Company shall (i) pay a dividend or make a
                distribution in shares of Common Stock, (ii) subdivide its
                outstanding shares of Common Stock into a greater number of
                shares of Common Stock, (iii) combine its outstanding shares of
                Common Stock into a smaller number of shares of Common Stock,
                (iv) make a distribution on its Common Stock in shares of its
                capital stock other than Common Stock, or (v) issue by
                reclassification of its Common Stock other securities of the
                Company, the conversion privilege of the Debenture and the
                Conversion Price then in effect immediately prior thereto shall
                be adjusted so that the Holder shall be entitled to receive the
                kind and number of shares of Common Stock and

                                       3
<PAGE>   4

                other securities of the Company which it would have owned or
                would have been entitled to receive after the happening of any
                of the events described above, had the Debenture been converted
                immediately prior to the happening of such event or any record
                date with respect thereto. Any adjustment made pursuant to this
                paragraph (a) shall become effective immediately after the
                effective date of such event retroactive to the record date, if
                any, for such event.

            (b) In case the Company shall distribute to all holders of its
                shares of Common Stock (i) debt securities or other evidences
                of its indebtedness which are not convertible into Common Stock
                or (ii) assets (excluding cash dividends or distributions out
                of earnings), then the Conversion Price shall be determined by
                dividing the then current Conversion Price by a fraction, of
                which the numerator shall be the higher of the then Current
                Market Price, or the Conversion Price on the date of such
                distribution, and of which the denominator shall be such
                Current Market Price, or such Conversion Price on such date
                minus the then fair value of the portion of the assets or
                evidences of indebtedness so distributed applicable to one
                share of Common Stock. Such adjustment shall be made whenever
                any such distribution is made and shall become effective on the
                date of distribution retroactive to the record date for the
                determination of stockholders entitled to receive such
                distribution. The fair value of such assets shall be determined
                in good faith by the Board of Directors of the Company.

            (c) No adjustment in the Conversion Price shall be required in the
                following events:

                (i)  If the amount of such adjustment would be less than $.05
                     per share; provided, however, that any adjustment which by
                     reason of this paragraph 5.5(c)(i) is not required to be
                     made immediately shall be carried forward and taken into
                     account in any subsequent adjustment; or

                (ii) The issuance of options under the Company's existing stock
                     option plans and future stock option plans approved by the
                     Company's shareholders.

            (d) When the number of shares of Common Stock or the Conversion
                Price is adjusted as herein provided, the Company shall cause
                to be promptly mailed to the Holder by first class mail,
                postage prepaid, notice of such adjustment or adjustments and a
                certificate from the Company's Chief Financial Officer setting
                forth the number of shares of Common Stock and the Conversion
                Price after such adjustment, a brief statement of the facts
                requiring such adjustment and the computation by which such
                adjustment was made.

                                       4

            (e) For the purpose of this Section 5.5, the following shall apply:

                (i)  The term "Common Stock" shall mean (A) the class of stock
                     designated as the Common Stock of the Company at the date
                     of this Debenture or (B) any other class of stock
                     resulting from successive changes or reclassification of
                     such Common Stock consisting solely of changes in par
                     value, or from par value to no par value, or from no par
                     value to par value. In the event that any time, as a
                     result of an adjustment made pursuant to this Section 5.5,
                     the Holder shall become entitled to receive any securities
                     upon conversion of the Company other than shares of Common
                     Stock thereafter the number of such other securities and
                     the Conversion Price of such securities shall be subject
                     to adjustment from time to time in a manner and on terms
                     as nearly equivalent as practicable to the provisions with
                     respect to the Common Stock contained in this Section 5.5.

                (ii) If the Common Stock is traded on a securities exchange or
                     over the counter, the "Current Market Price: for purposes
                     of this section 5.5 shall mean the average of the Current
                     Market Prices for the five consecutive trading days
                     immediately prior to the date of the event which
                     necessitates an adjustment to the Conversion Price.

            5.6 No Adjustment for Dividends. Except as provided in Section 5.5,
no adjustment in respect to any dividends paid shall be made during the term of
the Debenture or upon the Exercise of the Debenture.

            5.7 Preservation of Purchase Rights Upon Reclassification
Consolidation, etc. In the case of any consolidation of the Company with or
merger of the Company into another corporation or in the case of any sale or
conveyance to another corporation of all or substantially all of the property,
assets or business of the Company, the Company or such successor or purchasing
corporation, as the case may be, shall provide that the Holder shall have the
right thereafter upon payment of the Conversion Price in effect immediately
prior to such action to purchase upon conversion of the Debenture the kind and
amount of shares and other securities and property which the Holder would have
owned or have been entitled to receive after the happening of such
consolidation, merger, sale or conveyance had the Debenture been converted
immediately prior to such action. Such agreement shall provide for adjustments,
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Section 5. The provisions of this Section 5.7 shall
similarly apply to successive consolidations, mergers, sales or conveyances.

            5.8 Par Value of Common Stock. Before taking any action which would
cause an adjustment reducing the Conversion Price below the then par value of
the shares of Common Stock issuable upon conversion of the Debenture, the
Company will take any corporate action which may, in the opinion of its
counsel, be necessary in order that the Company may

                                       5
<PAGE>   6

validly and legally issue fully paid and nonassessable shares of Common Stock
at such adjusted Conversion Price.

            5.9 Statement on Debenture Certificates. Irrespective of any
adjustments in the Conversion Price or the number of securities convertible,
this Debenture certificate or any certificates hereafter issued may continue to
express the same price and number of securities as are stated in this Debenture
certificate. However, the Company may at any time in its sole discretion (which
shall be conclusive) make any change in the form of the Debenture certificate
that it may deem appropriate and that does not affect the substance thereof;
and any Debenture certificate thereafter issued, whether upon registration or
transfer of, or in exchange or substitution for, an outstanding Debenture
certificate, may be in the form so changed.

         6. Registration Rights: Liquidated Damages. The Holder will be
entitled to registration rights in respect of the shares of Common Stock
issuable upon conversion of the Debentures and exercise of the Warrants (the
terms of which are set forth below) as follows: (1) The Company shall prepare
and file, within 90 days of the initial Closing Date, Registration Statement on
Form S-3, if eligible, or Form S-1 or SB-2, whichever is applicable (the
"Registration Statement") with the Securities and Exchange Commission (the
"Commission") covering the resale of the shares of Common Stock issuable upon
conversion of the Debentures and issuable upon the exercise of the Warrants.
The Company shall use its best efforts to cause the Registration Statement to
be declared effective by the Commission no later than 150 days following the
initial Closing Date and shall promptly deliver to Holder copies of all
amendments to such Registration Statement and correspondence with the
Commission with respect thereto. The Company shall maintain the effectiveness
of the Registration Statement until all of the Common Stock issuable or issued
upon conversion or exercise of the Warrants has been sold. The Company shall
pay all expenses of registration (other than underwriting fees and discounts in
respect of shares of Common Stock offered and sold under such Registration
Statement by the Holder, if any). (2) If the Registration Statement is not
declared effective by the Commission during the 150 day period mentioned above,
the Company shall pay promptly in cash or free trading common stock valued at
the Conversion Price, as hereinafter defined, to the Holder, as liquidated
damages and not as a penalty, an amount equal to one percent (1%) per month
commencing 150 and ending 180 days after the initial Closing of the outstanding
principal amount of the Debentures, in the event that the Registration
Statement is not declared effective by the Commission by the 180th day,
liquidated damages shall be increased to two percent (2%) per month from 180
days after the Closing date until the Registration Statement is declared
effective.

         7. Fractional Shares. No Fractional shares of Common Stock will be
issued in connection with any conversion hereunder but in lieu of such
fractional shares, the Company shall make a cash payment therefor equal in
amount to the product of the applicable fraction multiplied by the Conversion
Price then in effect.

         8. Subordination. Any right of the Holder to payment of principal or
interest from the Company shall be subordinated to the claims and rights of the
holders of the Senior Debt ("Senior Debt Holders"), "Senior Debt" means all
Indebtedness of the Company other than the Debentures, whether outstanding on
the date of execution of this Debenture or thereafter created,

                                       6
<PAGE>   7

incurred or assumed, except (x) any such Indebtedness that by the terms of the
instrument or instruments by which such Indebtedness was created, assumed or
incurred expressly provides that it (i) is junior in right of payment to the
Debentures or (ii) ranks pari passu in right of payment with the Debentures and
(y) any amendments, modifications or supplements to, or any renewals,
extensions, deferrals, refinancing and refunding of, any of the foregoing. Any
cash payment of principal or interest to the Holder shall be collected,
enforced or received by the Holder as trustee for the Senior Debt Holders and
paid over to the Senior Debt Holders. The Holder agrees that in the event of
any payment of principal or interest by the Company to the Holder by reason of
any receivership, insolvency or bankruptcy proceeding, or proceeding for
reorganization or readjustment of the Company or its properties, or otherwise,
then, in any such event, the Senior Debt Holders shall be preferred in the
payment of their claims over the claim of the Holder to payment of principal or
interest against the Company or its properties, and the claims of the Senior
Debt Holders shall be first paid and satisfied in full before any payment or
distribution of any kind or character, whether in cash or property, shall be
made to the Holder. Provided, however, that this Section 8 shall not apply to
any payment of principal or interest made to the Holder while the Company is
solvent and not in default with respect to its Senior Debt.

         9. Replacement of Debenture Certificate. Upon receipt of evidence
satisfactory to the Company of the certificate loss, theft, destruction or
mutilation of the Debenture certificate and, in the case of any such loss,
theft or destruction, upon delivery of a bond of indemnity satisfactory to the
Company, or, in the case of any such mutilation, upon surrender and
cancellation of the Debenture certificate, the Company will issue a new
Debenture certificate, of like tenor, in lieu of such lost, stolen, destroyed
or mutilated Debenture certificate.

        10. Covenants of the Company. So long as any of the Debentures remain
outstanding, the Company shall not, without the consent of the holder hereof,
which consent will not be unreasonably withheld:

            (a) At all times keep reserved the total number of shares of Common
                Stock necessary for the conversion of all of the then
                outstanding Debentures at the then current Conversion Rate;

            (b) Not pay any dividends in cash and/or property or other assets
                of the Company in respect of its Common Stock or otherwise.

            (c) Not issue any debentures of the Company other than the
                Debentures unless the rights of the holders of such debentures
                are pari passu or subordinate to the Debentures;

            (d) Not without the consent of Holder enter into a loan secured by
                the property and/or assets of the Company or any of its
                subsidiaries with (i) any director, officer or 5% stockholder
                of the Company, (ii) any entity in which a director, officer of
                5% stockholder has an interest as an officer,

                                       7
<PAGE>   8

                director, partner, beneficiary of a trust or is a 5% or more
                equity holder of such entity, or (iii) any parent, spouse,
                child or grandchild of an officer, director or 5% stockholder
                of the Company upon terms no less favorable to the Company than
                those which could be obtained from an "arms-length" lender; and

            (e) Not redeem, repurchase or otherwise acquire any shares of the
                common or preferred stock of the Company.

        11. Default. If any of the following events (herein called "Events of
Default") shall occur:

            (a) if the Company shall default in the payment or prepayment of
                any part of the principal of any of the Debentures after the
                same shall become due and payable, whether at maturity or at a
                date fixed for prepayment or by acceleration or otherwise, and
                such default shall continue for more than 30 days; or

            (b) if the Company shall default in the payment of any installment
                of interest on any of the Debentures for more than 30 days
                after the same shall become due and payable; or

            (c) if the Company shall make an assignment for the benefit of
                creditors or shall be unable to pay its debts as they become
                due; or

            (d) if the Company shall dissolve; terminate its existence (except
                in the case of a merger or consolidation); become insolvent on
                a balance sheet basis; commence a voluntary case under the

                generally to pay its debts as such debts become due; or

            (e) if the Company shall default in the performance of or
                compliance with any agreement, condition or term contained in
                this Debenture or any of the other Debentures and such default
                shall not have been cured within 30 days after such default; or

then and in any such event the Holder of this Debenture shall have the option
(unless the default shall have theretofore been cured) by written notice to the
Company to declare the Debenture to be due and payable, whereupon the Debenture
shall forthwith mature and become due and payable, at the applicable prepayment
price on the date of such notice, without presentment, demand, protest or
further notice of any kind, all of which are hereby expressly waived, anything
contained in this Debenture to the contrary notwithstanding. Upon the
occurrence of an Event of

                                       8
<PAGE>   9

Default, the Company shall promptly notify the Holder of this Debenture in
writing setting out the nature of the default in reasonable detail.

        12. Remedies on Default; Notice to Other Holders. In case any one or
more of the Events of Default shall occur, the Holder may proceed to protect
and enforce his or her rights by a suit in equity, action at law or other
appropriate proceeding, whether, to the extent permitted by law, for the
specific performance of any agreement of the Company contained herein or in aid
of the exercise of any power granted hereby. If any Holder of one or more of
the Debentures shall declare the same due and payable or take any other action
against the Company in respect of an Event of Default, the Company will
forthwith give written notice to the Holder of this Debenture, specifying such
action and the nature of the default alleged.

        13. Amendments. With the consent of the Holders of more than 50% in
aggregate principal amount of the Debentures at the time outstanding, the
Company, when authorized by a resolution of its Board of Directors, may enter
into a supplementary agreement for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Debenture
or of any supplemental agreement or modifying in any manner the rights and
obligations of the holders of Debentures or Common Stock issued upon conversion
of the Debentures, and of the Company, provided, however, that no such
supplemental agreement shall (a) extend the fixed maturity of any Debenture, or
reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or alter or impair the right to convert the same
into Common Stock at the rates and upon the terms provided in this Debenture,
without the consent of the Holder of each of the Debentures so affected, or (b)
reduce the aforesaid percentage of Debentures, the Holders of which are
required to consent to any supplemental agreement, without the consent of the
Holders of all Debentures then outstanding.

        14. Changes, Waivers, etc. Neither this Debenture nor any provisions
hereof may be changed, waived, discharged or terminated orally, but only by a
statement in writing signed by the party against which enforcement of the
change, waiver, discharge or termination is sought, except to the extent
provided in Section 13 of this Debenture.

        15. Entire Agreement. This Debenture embodies the entire agreement and
understanding between the Holder and the Company and supercedes all prior
agreements and understandings relating to the subject matter hereof.

        16. Governing Law, Jurisdiction, etc.

            (a) It is the intention of the parties that the laws of the State
                of Florida shall govern the validity of this Debenture, the
                construction of its terms and the interpretation of the rights
                and duties of the parties.

            (b) In the event of any dispute, question, controversy or claim
                arising among the parties hereto which shall arise out of or in
                connection with this Debenture, the parties shall keep the
                proceeding related to such controversy in strict confidence and
                shall not disclose the nature of said dispute, the status of
                the proceeding or any testimony, documents or

                   PROGRESSIVE TELECOMMUNICATIONS CORPORATION

              THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE
               UPON THE EXERCISE OF THIS WARRANT ARE TRANSFERABLE

           Void after 5:00 P.M., New York Time, on December 31, 2002

                              Warrant to Purchase
                               __________ Shares
                                of Common Stock

                        WARRANT TO PURCHASE COMMON STOCK

This is to Certify That, FOR VALUE RECEIVED, __________________________________,
a____________________________________________________________, having an office
at ________________________________________________________________________(the
"Holder") is entitled to purchase, subject to the provisions of this Warrant,
from Progressive Telecommunications Corporation, a company organized under the
laws of the State of Nevada, having an office at 601 Cleveland Street, Suite
930, Clearwater, Florida 33755 (the "Company"), the number of shares set forth
above (the "Warrant Shares") of the Company's Common Stock, $.001 par value
("Common Stock") at a price of $1.50 per share (or such other price computed by
applying all adjustments made on or before December 31, 2002, in accordance
with Section F hereof, to $1.50 as if it had been the initial Exercise Price
per share hereunder) at any time on or after December 31, 1999 until 5:00 P.M.
New York Time, on December 31, 2002. The number of shares of Common Stock to be
received upon the exercise of this Warrant and the price to be paid for a share
of Common Stock may be adjusted from time to time as hereinafter set forth. The
shares of Common Stock deliverable upon such exercise, and as adjusted from
time to time, are hereinafter sometimes referred to as "Warrant Shares" and the
exercise price of a share of Common Stock in effect at any time and as adjusted
from time to time is hereinafter sometimes referred to as the "Exercise Price."

The Warrants represented by the Certificate are part of an authorized class of
2,000,000 Warrants.

A. EXERCISE OF WARRANT. Subject to the following conditions precedent and the
   provisions of Section H hereof, this Warrant may be exercised in whole or in
   part at any time or from time to time on or after December 31, 1999, and
   before 5:00 P.M. New York Time on December 31, 2002, or, if either such day
   is a day on which banking institutions are authorized by law to close, then
   on the next succeeding day which shall not be such a day, by presentation
   and surrender hereof to the Company at any office maintained by it in
   Clearwater, Florida, or at the office of its Warrant Agent, if any, with

                                       1
<PAGE>   2

   the Purchase Form annexed hereto duly executed and accompanied by payment of
   the Exercise Price for the number of shares specified in such form. 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 rights of the Holder hereof to purchase the balance of the
   shares purchasable hereunder. Upon receipt by the Company of this Warrant at
   its office, or by the Warrant Agent of the Company at its office, in proper
   form for exercise, the Holder shall be deemed to be the holder of record of
   the shares of Common Stock issuable upon such exercise, notwithstanding that
   the stock transfer books of the Company shall then be closed or that
   certificate representing such shares of Common Stock shall not then be
   actually delivered to the Holder.

B. RESERVATION OF SHARES. The Company hereby agrees that at all times there
   shall be reserved for issuance and/or delivery upon exercise of this Warrant
   such number of shares of its Common Stock as shall be required for issuance
   of delivery upon exercise of this Warrant.

C. FRACTIONAL SHARES. No fractional shares or scrip representing fractional
   shares shall be issued upon the exercise of this Warrant. With respect to
   any fraction of a share called for upon exercise hereof, the Company shall
   issue to the Holder the next whole share.

D. EXCHANGE, ASSIGNMENT OR LOSS OF WARRANT. This Warrant is exchangeable,
   without expense, at the option of the Holder, upon presentation and
   surrender hereof to the Company or at the office of the Warrant Agent for
   other Warrants of different denominations entitling the holder thereof to
   purchase in aggregate the same number of shares of Common Stock purchasable
   hereunder. The term Warrant as used herein includes any Warrants into which
   this Warrant may be divided or exchanged. Upon receipt by the Company of
   evidence reasonably satisfactory to it of the loss, theft, destruction, or
   mutilation of this Warrant, and (in the case of loss, theft or destruction)
   of reasonably satisfactory indemnification, and upon surrender and
   cancellation of this Warrant, if mutilated, the Company will execute and
   deliver a new Warrant of like tenor and date. Any such new warrant executed
   and delivered shall constitute an additional contractual obligation on the
   part of the Company, whether or not this Warrant so lost stolen, destroyed,
   or mutilated shall be at any time enforceable by anyone.

E. RIGHTS OF THE HOLDER. The Holder shall not, by virtue here of, be entitled
   to any rights of a shareholder in the Company, either at law or equity, and
   the rights of the Holder are limited to those expressed in the Warrant and
   are not enforceable against the Company except to the extent set forth
   herein.

F. STOCK DIVIDENDS, RECLASSIFICATION, REORGANIZATION, ANTI-DILUTION PROVISIONS,
   ETC. This Warrant is subject to the following further provisions:

                                       2
<PAGE>   3

   1. In case, prior to the expiration of this Warrant by exercise or by its
      terms, the Company shall issue any shares of its Common Stock as a stock
      dividend or subdivide the number of outstanding shares of Common Stock
      into a greater number of shares, then, in either of such cases, the
      Exercise Price per share of the Warrant Shares purchasable pursuant to
      this Warrant in effect at the time of such action shall be
      proportionately reduced and the number of Warrant Shares at that time
      purchasable pursuant to this Warrant shall be proportionately increased;
      and conversely, in the event the Company shall contract the number of
      outstanding shares of Common Stock by combining such shares into a
      smaller number of shares, then, in such case, the Exercise Price per
      share of the Warrant Shares purchasable pursuant to this Warrant in
      effect at the time of such action shall be proportionately increased and
      the number of Warrant Shares at that time purchasable pursuant to this
      Warrant shall be proportionately decreased. Provided however, the maximum
      Exercise Price shall not exceed $15.00 and the corresponding minimum
      number of Warrant Shares issuable upon exercise hereof shall equal the
      number determined by multiplying the initial number of Warrant Shares
      which could be obtained upon exercise by $1.50 and dividing the product
      so obtained by $15.00. Any dividend paid or distributed upon the Common
      Stock in stock of any other class of securities convertible into shares
      of Common Stock shall be treated as a dividend paid in Common Stock to
      the extent that shares of Common Stock are issuable upon the conversion
      thereof.

   2. In case, prior to the expiration of this Warrant by exercise or by its
      terms, the Company shall be recapitalized by reclassifying its
      outstanding Common Stock, $.001 par value, into stock with a different
      par value or by changing its outstanding Common Stock with par value to
      stock without par, the Company or a successor corporation shall be
      consolidated or merge with or convey all or substantially all of its or
      of any successor corporation's property and assets to any other
      corporation or corporations (any such corporation being included within
      the meaning of the term successor corporation in the event of any
      consolidation or merger of any such corporation with, or the sale of all
      or substantially all of the property of any such corporation to, another
      corporation or corporations), in exchange for stock or securities of a
      successor corporation, the holder of this Warrant shall thereafter have
      the right to purchase upon the terms and conditions and during the time
      specified in this Warrant, in lieu of the Warrant Shares theretofore
      purchasable upon the exercise of this Warrant, the kind and amount of
      shares of stock and other securities receivable upon such
      recapitalization or consolidation, merger or conveyance by a holder of
      the number of shares of Common Stock which the holder of this Warrant
      might have purchased immediately prior to such recapitalization or
      consolidation, merger or conveyance.

   3. Upon the occurrence of each event requiring an adjustment of the Exercise
      Price and of the number of Warrant Shares purchasable at such adjusted
      Exercise Price by reason of such event in accordance with the provisions
      of this Section F, the

                                       3
<PAGE>   4

      Company shall compute the adjusted Exercise Price and the adjusted number
      of Warrant Shares purchasable at such adjusted Exercise Price by reason
      of such event in accordance with the provisions of this Section F and
      shall prepare a certificate setting forth such adjusted Exercise Price
      and the adjusted number of Warrant Shares and showing in detail the facts
      upon which such conclusions are based. The Company shall mail forthwith
      to each holder of this Warrant a copy of such certificate, and thereafter
      said certificate shall be conclusive and shall be binding upon such
      holder unless contested by such holder by written notice to the Company
      within thirty (30) days after receipt of the certificate by such holder.

   4. In case:

      (a) the Company shall take a record of the holders of its Common Stock
          for the purpose of entitling them to receive a dividend or any other
          distribution in respect of the Common Stock (including cash),
          pursuant to without limitation, any spin-off, split-off or
          distribution of the Company's assets; or

      (b) the Company shall take a record of the holders of its Common Stock
          for the purpose of entitling them to subscribe for or purchase any
          shares of stock of any class or to receive any other rights; or

      (c) of any classification, reclassification or other reorganization of
          the capital stock of the Company, consolidation or merger of the
          Company with or into another corporation, or conveyance of all or
          substantially all of the assets of the Company; or

      (d) of the voluntary or involuntary dissolution, liquidation or winding
          up of the Company;

      then, and in any such case, the Company shall mail to the Holder, at
      least twenty (20) days prior thereto, a notice stating the date or
      expected date on which a record is to be taken for the purpose of such
      dividend or distribution of rights, or the date on which such
      classification, reclassification, reorganization, consolidation, merger,
      conveyance, dissolution, liquidation, or winding up is to take place, as
      the case may be. Such notice shall also specify the date or expected
      date, if any is to be fixed, as of which holders of Common Stock of
      record shall be entitled to participate in said dividend or distribution
      of rights, or shall be entitled to exchange their shares of Common stock
      for securities or other property deliverable upon such classification,
      reclassification, reorganization, consolidation, merger, conveyance,
      dissolution, liquidation, or winding up, as the case may be. The failure
      to give such notice shall not affect the validity of any such proceeding
      or transaction and shall not affect the right of the holder of this
      Warrant to participate in said dividend, distribution of rights, or any
      such exchange and acquire the kind and amount of cash, securities or
      other property as

                                       4
<PAGE>   5

      the Holder would have been entitled to acquire if it was the record
      holder of the Warrant Shares which could be obtained upon the exercise of
      the Warrants immediately before such proceeding or transaction; provided
      that, the Holder exercises the Warrants within 30 days after discovery
      that such action or proceeding has taken place.

   5. In case the Company at any time while this Warrant shall remain unexpired
      and unexercised, shall dissolve, liquidate, or wind up its affairs, the
      holder of this Warrant may thereafter receive upon exercise hereof in
      lieu of each share of Common Stock of the Company which it would have
      been entitled to receive, the same kind and amount of any securities or
      assets as may be issuable, distributable or payable upon any such
      dissolution, liquidation or winding up with respect to each share of
      Common Stock of the Company.

G. OFFICER'S CERTIFICATE. Whenever the Exercise Price shall be adjusted as
   required by the provisions of the foregoing Section, the Company shall
   forthwith file in the custody of its Secretary at its principal office and
   with the Warrant Agent, if any, an officer's certificate showing the
   adjusted Exercise Price determined as therein provided, setting forth in
   reasonable detail the facts requiring such adjustment, including a statement
   of the number of additional shares of Common Stock, if any, the
   consideration for such shares, determined as provided in such Section F, and
   such other facts as shall be necessary to show the reason for and the manner
   of computing such adjustment. Each such officer's certificate shall be made
   available at all reasonable times for inspection by the holder and the
   Company shall, forthwith after each such adjustment, mail a copy of such
   certificate to the holder.

H. TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933. Neither this Warrant,
   the Warrant Shares, nor any other security issued or issuable upon exercise
   of this Warrant may be sold or otherwise disposed or except as follows:

   1. to a person who, in the opinion of counsel reasonably satisfactory to the
      Company, is a person to whom the Warrant or Warrant Shares may legally be
      transferred without registration and without the delivery of a current
      prospectus under the Securities Act of 1933, as amended (the "Act") with
      respect thereto and then only against receipt of an agreement of such
      person to comply with the provisions of this Section H with respect to
      any resale or other disposition of such securities; or

   2. to any person upon delivery of a prospectus then meeting the requirements
      of the Act relating to such securities and the offering thereof for such
      sale or disposition.

I. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

   The Company represents and warrants to the holder as follows:

                                       5
<PAGE>   6

   1. The Company is duly organized and, as of the date of the original
      issuance hereof, validly existing and in good standing under the laws of
      the State of Nevada.

   2. The Company shall at all times reserve and keep available out of its
      authorized shares of Common Stock, solely for the purpose of issuing
      Warrant Shares upon the exercise of this Warrant, such shares as may be
      issuable upon the exercise hereof.

   3. Warrant Shares, when issued and paid for in accordance with the terms of
      this Warrant, will be fully paid and not assessable.

   4. This Warrant has been duly authorized and approved by all required
      corporate action by the Company and does not violate the certificate of
      incorporation or by-laws of the Company.

J. REGISTRATION RIGHTS: LIQUIDATED DAMAGES. The Holder will be entitled to
   registration rights in respect of the shares of Common Stock issuable upon
   conversion of the Debentures and exercise of the Warrants (the terms of
   which are set forth below) as follows: (1) The Company shall prepare and
   file, within 90 days of the initial Closing Date, Registration Statement on
   Form S-3 or such other applicable Registration Statement (the "Registration
   Statement") with the Securities and Exchange Commission (the "Commission")
   covering the resale of the shares of Common Stock issuable upon the exercise
   of the Warrants. The Company shall use its best efforts to cause the
   Registration Statement to be declared effective by the Commission no later
   than 150 days following the initial Closing Date and shall promptly deliver
   to Purchaser copies of all amendments to such Registration Statement and
   correspondence with the Commission with respect thereto. The Company shall
   maintain the effectiveness of the Registration Statement until all of the
   Common Stock issuable or issued upon conversion or exercise of the Warrants
   has been sold. The Company shall pay all expenses of registration (other
   than underwriting fees and discounts in respect of shares of Common Stock
   offered and sold under such Registration Statement by the Purchaser, if
   any). (2) If the Registration Statement is not declared effect by the
   Commission during the 150 day period mentioned above, the Company shall pay
   promptly in cash or free trading common stock valued at the Conversion
   Price, as hereinafter defined, to the Holder, as liquidated damages and not
   as a penalty, an amount equal to one percent (1%) per month commencing 150
   and ending 180 days after the initial Closing of the outstanding principal
   amount of the Debentures, in the event that the Registration Statement is
   not declared effective by the Commission by the 180th day, liquidated
   damages shall be increased to two percent (2%) per month from 180 days after
   the Closing date until the Registration Statement is declared effective.
