           VOID AFTER 3:30 P.M., MOUNTAIN TIME, ON THE EXPIRATION DATE

                        WARRANT TO PURCHASE COMMON SHARES

                                POPMAIL.COM, INC.
Warrant No. EB-2

         This is to Certify That, FOR VALUE RECEIVED, AMERICAN FRONTEER
FINANCIAL CORPORATION, 1700 Lincoln Street, 32nd Floor, Denver, Colorado 80203
("Holder"), is entitled to purchase, subject to the provisions of this Warrant,
from POPMAIL.COM, INC. ("Company"), a Minnesota corporation, at any time until
3:30 P.M., Mountain Time, on December 10, 2004 ("Expiration Date"), 19,500
Common Shares of the Company. Notwithstanding the foregoing, the Holder shall be
required to exercise this Warrant during the thirty (30) days after the last
trading day that the closing bid price of a Common Share exceeds $6.00 (as
adjusted in the same manner that adjustments in the Exercise Price are made as
provided herein) for twenty (20) consecutive trading days. If not exercised
during such thirty (30) day period, the Expiration Date shall be the thirtieth
day. The purchase price per Common Share shall initially be $2.00. The number of
Common Shares to be received upon the exercise of this Warrant and the price to
be paid for a Common Share may be adjusted from time to time as hereinafter set
forth. The purchase price of a Common Share in effect at any time and as
adjusted from time to time is hereinafter sometimes referred to as the "Exercise
Price." This Warrant is or may be one of a series of warrants identical in form
issued by the Company to purchase Common Shares of the Company and the term
"Warrants" as used herein means all such Warrants (including this Warrant). The
Common Shares, as adjusted from time to time, underlying the Warrants are
hereinafter sometimes referred to as "Warrant Shares" and include all Common
Shares that have been issued upon the exercise of the Warrants and all unissued
Common Shares underlying the Warrants.

         (A) EXERCISE OF WARRANT. This Warrant may be exercised in whole or in
part at any time or from time to time until the Expiration Date or if the
Expiration Date 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 or at the office of its stock
transfer agent, if any, with the Purchase Form annexed hereto duly executed and
accompanied by payment of the Exercise Price for the number of Common Shares
specified in such Form, together with all federal and state taxes applicable
upon such exercise. The Company agrees not to merge, reorganize or take any
action that would terminate this Warrant unless provisions are made as part of
such merger, reorganization or other action which would provide the holders of
this Warrant with an equivalent of this Warrant as specified in Section (i)
hereof. The Company agrees to provide notice to the Holder that any tender offer
is being made for the Company's Common Shares no later than three business days
after the day the Company becomes aware that any tender offer is being made for
outstanding Common Shares of the Company. If this Warrant should be exercised in
part only, the Company shall, upon surrender of this Warrant for cancellation,
execute and deliver a new Warrant evidencing the right of the Holder to purchase
the balance of the Common Shares purchasable hereunder. Upon receipt by the
Company of this Warrant at the office of the Company or at the office of the
Company's stock transfer agent, in proper form for exercise and accompanied by
the

<PAGE>   2

Purchase Form and the Exercise Price, the Holder shall be deemed to be the
holder of record of the Common Shares issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such Common Shares 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 Common Shares as shall be required for issuance or
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 Common Share called for upon any exercise hereof,
the Company shall, upon receipt by the Company or the Company's stock transfer
agent of the Exercise Price on such fractional share, pay to the Holder an
amount in cash equal to such fraction multiplied by the current value of such
fractional share, determined as follows:

                  (1) If the Common Shares are listed on a national securities
         exchange or a foreign exchange, are admitted to unlisted trading
         privileges on such an exchange, or are listed for trading on a trading
         system of the National Association of Securities Dealers, Inc. ("NASD")
         such as The Nasdaq SmallCap Market ("SCM") or the Nasdaq National
         Market ("NNM") or the OTC Bulletin Board, then the current value shall
         be the last reported sale price of the Common Shares on such an
         exchange or system on the last business day prior to the date of
         exercise of this Warrant or if no such sale is made on such day, the
         average of the closing bid prices for the Common Shares for such day on
         such exchange or such system shall be used; or

                  (2) If the Common Shares are not so listed on such exchange or
         system or admitted to unlisted trading privileges, the current value
         shall be the average of the last reported bid prices reported by the
         National Quotation Bureau, Inc. on the last business day prior to the
         date of the exercise of this Warrant; or

                  (3) If the Common Shares are not so listed or admitted to
         unlisted trading privileges and if bid prices are not so reported, the
         current value shall be an amount, not less than book value, determined
         in such reasonable manner as may be prescribed by the board of
         directors of the Company.

         (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 its stock transfer
agent, if any, for other Warrants of different denominations entitling the
Holder thereof to purchase (under the same terms and conditions as provided by
this Warrant) in the aggregate the same number of Common Shares purchasable
hereunder. This Warrant may not be sold, transferred, assigned, or hypothecated
except in compliance with federal and state securities laws. Any transfer or
assignment shall be made by surrender of this Warrant to the Company or at the
office of its stock transfer agent, if any, with the Assignment Form annexed
hereto duly executed and with funds sufficient to pay any transfer tax;

                                       2

<PAGE>   3

whereupon the Company shall, without charge, execute and deliver a new Warrant
in the name of the assignee named in such instrument of assignment and this
Warrant shall promptly be canceled. This Warrant may be divided or combined with
other Warrants which carry the same rights upon presentation hereof at the
office of the Company or at the office of its stock transfer agent, if any,
together with a written notice specifying the names and denominations in which
new Warrants are to be issued and signed by the Holder hereof. The term
"Warrant" as used herein includes any warrants issued in substitution for or
replacement of this Warrant, or into which this Warrant may be divided or
exchanged. Upon receipt by the Company of evidence 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. Subject to such right
of indemnification, 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 hereof, 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)      ADJUSTMENT PROVISIONS.

                  (1)      Adjustments of the Exercise Price.

                           (A) If the Company subdivides its outstanding Common
                  Shares into a greater number of Common Shares, the Exercise
                  Price in effect immediately prior to such subdivision shall be
                  proportionately reduced. Conversely, if the Company combines
                  its outstanding Common Shares into a lesser number of Common
                  Shares, the Exercise Price in effect immediately prior to such
                  combination shall be proportionally increased. In case of a
                  subdivision or combination, the adjustment of the Exercise
                  Price shall be made as of the effective date of the applicable
                  event. A distribution on Common Shares, including a
                  distribution of Convertible Securities, to shareholders of the
                  Company on a pro rata basis shall be considered a subdivision
                  of Common Shares for the purposes of this subsection (1)(A) of
                  this Section, except that the adjustment will be made as of
                  the record date for such distribution and any such
                  distribution of Convertible Securities shall be deemed to be a
                  distribution of the Common Shares underlying such Convertible
                  Securities.

                           (B) If the Company shall at any time distribute or
                  cause to be distributed to its shareholders, on a pro rata
                  basis, cash, assets, or securities of any entity other than
                  the Company, then the Exercise Price in effect immediately
                  prior to such distribution shall automatically be reduced by
                  an amount determined by dividing (x) the amount (if cash) or
                  the value (if assets or securities) of the holders' of
                  Warrants (as such term is defined in the first paragraph
                  hereof) pro rata share of such distribution determined
                  assuming that all holders of Warrants had exercised their

                                       3

<PAGE>   4

                  Warrants on the day prior to such distribution, by (y) the
                  number of Common Shares issuable upon the exercise of Warrants
                  (as such term is defined in the first paragraph hereof) by the
                  holders thereof on the day prior to such distribution.

                           (C) If the Company defaults in making any payment
                  required pursuant to a promissory note dated December 10,
                  1999, in the amount of $325,000 from the Company to eBanker
                  USA.com, Inc., the Exercise Price shall be reduced to $0.01.

                  (3) No Adjustment for Small Amounts. Anything in this Section
         (f) to the contrary notwithstanding, the Company shall not be required
         to give effect to any adjustment in the Exercise Price unless and until
         the net effect of one or more adjustments, determined as above
         provided, shall have required a change of the Exercise Price by at
         least one cent, but when the cumulative net effect of more than one
         adjustment so determined shall be to change the actual Exercise Price
         by at least one cent, such change in the Exercise Price shall thereupon
         be given effect.

                  (4) Number of Shares Adjusted. Upon any adjustment of the
         Exercise Price pursuant to subsection (1)(A) or (B) of this Section,
         the Holder of this Warrant shall thereafter (until another such
         adjustment) be entitled to purchase, at the new Exercise Price, the
         number of Common Shares, calculated to the nearest full share, obtained
         by multiplying the number of Common Shares initially issuable upon
         exercise of this Warrant by the Exercise Price specified in the first
         paragraph hereof and dividing the product so obtained by the new
         Exercise Price.

                  (5)      Definitions.

                           (A) Whenever reference is made in this Section (f) to
                  the distribution of Common Shares, the term "Common Shares"
                  shall mean the Common Shares of the Company authorized as of
                  the date hereof and any other class of stock ranking on a
                  parity with such Common Shares. However, subject to the
                  provisions of Section (i) hereof, Common Shares issuable upon
                  exercise hereof shall include only Common Shares of the class
                  designated as Common Shares of the Company as of the date
                  hereof.

                           (B) Whenever reference is made in this Section (f) to
                  the distribution of Convertible Securities, the term
                  "Convertible Securities" shall mean options or warrants or
                  rights for the purchase of Common Shares of the Company or for
                  the purchase of any stock or other securities convertible into
                  or exchangeable for Common Shares of the Company.

                  (6) Determination of Date of Issue. In case the Company shall
         take a record of the holders of Common Shares for the purpose of
         entitling them to receive a dividend or other distribution payable in
         Common Shares or in Convertible Securities, then such record date shall
         be deemed to be the date of the issue of the Common Shares deemed to
         have been

                                       4
<PAGE>   5

         issued upon the declaration of such dividend or the making of such
         other distribution, as the case may be.

                  (7)      Treasury  Shares.  For the purpose of this Section
         (f), Common Shares at any relevant time owned or held by, or for the
         account of, the Company shall not be deemed outstanding.

         (G) OFFICER'S CERTIFICATE. Whenever the Exercise Price shall be
adjusted as required by the provisions of Section (f) hereof, the Company shall
forthwith file in the custody of its Secretary or an Assistant Secretary at its
principal office, and with its stock transfer and warrant agent, if any, an
officer's certificate showing the adjusted Exercise Price determined as herein
provided and setting forth in reasonable detail the facts requiring 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, deliver a copy of such certificate to the Holder.

         (H) NOTICES TO HOLDERS. So long as this Warrant shall be outstanding
and unexercised (i) if the Company shall pay any dividend or make any
distribution upon the Common Shares or (ii) if the Company shall offer to the
holders of Common Shares for subscription or purchase by them any shares of
stock of any class or any other rights or (iii) if any capital reorganization of
the Company, reclassification of the capital stock of the Company, consolidation
or merger of the Company with or into another corporation, sale, lease or
transfer of all or substantially all of the property and assets of the Company
to another corporation, or voluntary or involuntary dissolution, liquidation or
winding up of the Company shall be effected, then, in any such case, the Company
shall cause to be delivered to the Holder, at least 10 days prior to the date
specified in (x) or (y) below, as the case may be, a notice containing a brief
description of the proposed action and stating the date on which (x) a record is
to be taken for the purpose of such dividend, distribution or rights, or (y)
such reclassification, reorganization, consolidation, merger, conveyance, lease,
dissolution, liquidation or winding up is to take place and the date, if any is
to be fixed, as of which the holders of Common Shares of record shall be
entitled to exchange their Common Shares for securities or other property
deliverable upon such reclassification, reorganization, consolidation, merger,
conveyance, dissolution, liquidation or winding up.

         (I) RECLASSIFICATION, REORGANIZATION OR MERGER. In case of any
reclassification, capital reorganization or other change of outstanding Common
Shares of the Company (other than a change in par value, or from par value to no
par value, or from no par value to par value, or as a result of an issuance of
Common Shares by way of dividend or other distribution or of a subdivision or
combination), or in case of any consolidation or merger of the Company with or
into another corporation (other than a merger with a subsidiary in which merger
the Company is the continuing corporation and which does not result in any
reclassification, capital reorganization or other change of outstanding Common
Shares of the class issuable upon exercise of this Warrant) or in case of any
sale or conveyance to another corporation of the property of the Company as an
entirety or substantially as an entirety, the Company shall cause effective
provision to be made so that the Holder shall have the right thereafter, by
exercising this Warrant, to purchase the kind and amount of shares of stock and
other securities and property which the Holder would have received upon such
reclassification, capital reorganization or other change, consolidation, merger,
sale or

                                       5
<PAGE>   6

conveyance had this Warrant been exercised prior to the consummation of
such transaction. Any such provision shall include provision for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Warrant. The foregoing provisions of this Section (i) shall
similarly apply to successive reclassifications, capital reorganizations and
changes of Common Shares and to successive consolidations, mergers, sales or
conveyances. In the event the Company spins off a subsidiary by distributing to
the shareholders of the Company as a dividend or otherwise the stock of the
subsidiary, the Company shall reserve for the life of this Warrant, shares of
the subsidiary to be delivered to the Holders of the Warrants upon exercise to
the same extent as if they were owners of record of the Warrant Shares on the
record date for distribution of the shares of the subsidiary.

         (J)      REGISTRATION UNDER THE SECURITIES ACT OF 1933.

                  (1) By no later than March 10, 2000, the Company will file and
         have declared effective a registration statement under the Securities
         Act of 1933, as amended (the "Act"), registering the Warrant Shares for
         resale. If for any reason such registration statement is not declared
         effective on or before March 10, 2000, the Exercise Price shall be
         reduced to $1.50. If such registration statement is not declared
         effective on or after March 11, 2000 and on or before April 9, 2000,
         the Exercise Price shall be reduced to $1.25 commencing April 10, 2000.
         The Exercise Price shall be reduced an additional $0.25 for each thirty
         (30) day period or portion thereof commencing May 10, 2000, that such
         registration statement is not declared effective; provided that, the
         Exercise Price shall not be reduced to below $0.25. Upon any reduction
         in the Exercise Price pursuant to this Section (j)(1), the number of
         Warrant Shares the Holder of this Warrant shall be entitled to purchase
         shall be increased to such number as is determined by dividing $39,000
         by the reduced Exercise Price. Nothing contained herein shall relieve
         the Company of the requirement to file and have declared effective such
         registration statement by March 10, 2000, or relieve the Company for
         liability for any damages that the Holder may incur as a result of the
         failure of the Company to comply with such requirement.

                  (2) In connection with such registration statement, the
         Company shall:

                           (A) Supply to each selling Holder a copy of the
                  registration statement and a reasonable number of copies of
                  the preliminary, final and other prospectus in conformity with
                  requirements of the Act and the Rules and Regulations
                  promulgated thereunder and such other documents as the Holders
                  shall reasonably request.

                           (B) Bear the complete cost and expense (other than
                  any selling commissions relating to the sale of the Warrant
                  Shares, which shall be paid by the sellers thereof) of such
                  registration statement.

                           (C) Keep effective such registration statement until
                  the first of the following events occur: (i) 12 months have
                  elapsed after the effective date of such registration
                  statement or (ii) all of the registered Warrant Shares issued
                  by the

                                       6

<PAGE>   7

                  Company either before or after the effective date of such
                  registration statement have been publicly sold under such
                  registration statement.

                           (D) Use its best efforts to register or qualify the
                  Warrant Shares for sale in those states requested by the
                  person selling the Warrant Shares; provided that, the Company
                  shall not be required to register or qualify Warrant Shares
                  for sale in any state in which the sale of the Warrant Shares
                  by the person selling the Warrant Shares would be exempt from
                  having to be registered or qualified in such state. The
                  determination of whether or not such an exemption exists shall
                  be made by counsel for the Company and such determination
                  shall be provided in writing to the person desiring to sell
                  Warrant Shares in a state.

                           (E) Indemnify and hold harmless each such Holder and
                  each underwriter, within the meaning of the Act, who may
                  purchase from or sell for any such Holder, any Warrant Shares,
                  from and against any and all losses, claims, damages, and
                  liabilities (including but not limited to, any and all
                  expenses whatsoever reasonably incurred in investigating,
                  preparing, defending or settling any claim) arising from (i)
                  any untrue or alleged untrue statement of a material fact
                  contained in any registration statement furnished pursuant to
                  clause (A) of this subsection, or any prospectus included
                  therein or (ii) any omission or alleged omission to state
                  therein a material fact required to be stated therein or
                  necessary to make the statements therein not misleading
                  (unless such untrue statement or omission or such alleged
                  untrue statement or omission was based upon information
                  furnished or required to be furnished in writing to the
                  Company by such Holder or underwriter expressly for use
                  therein), which indemnification shall include each person, if
                  any, who controls any such Holder or underwriter within the
                  meaning of the Act; provided, however, that the Company shall
                  not be so obligated to indemnify any such Holder or
                  underwriter or controlling person unless such Holder and
                  underwriter shall at the same time indemnify the Company, its
                  directors, each officer signing any registration statement or
                  any amendment to any registration statement and each person,
                  if any, who controls the Company within the meaning of the
                  Act, from and against any and all losses, claims, damages and
                  liabilities (including, but not limited to, any and all
                  expenses whatsoever reasonably incurred in investigating,
                  preparing, defending or settling any claim) arising from (i)
                  any untrue or alleged untrue statement of a material fact
                  contained in any registration statement or prospectus
                  furnished pursuant to Clause (A) of this subsection, or (ii)
                  any omission or alleged omission to state therein a material
                  fact required to be stated therein or necessary to make the
                  statements therein not misleading, but the indemnity of such
                  Holder, underwriter or controlling person shall be limited to
                  liability based upon information furnished, or required to be
                  furnished, in writing to the Company by such Holder or
                  underwriter or controlling person expressly for use therein.
                  The Company shall not be liable for amounts paid in settlement
                  of any such litigation if such settlement was effected without
                  the consent of the Company. The indemnity agreement of the
                  Company herein shall not inure to the benefit of any such
                  underwriter (or to the benefit of any person who controls such
                  underwriter) on account of any losses, claims, damages,

                  liabilities (or actions or proceedings in respect thereof)
                  arising from the sale of any of such Warrant Shares by such
                  underwriter to a person if such underwriter failed to send or
                  give a copy of the prospectus furnished pursuant to Clause (A)
                  of this subsection, as the same may then be supplemented or
                  amended (if such supplement or amendment shall have been
                  furnished to the Holders pursuant to said Clause (A)), to such
                  person with or prior to the written confirmation of the sale
                  involved.

                  (3) Each Holder shall supply such information as the Company
         may reasonably require from such Holder, or any underwriter for such
         Holders, for inclusion in such registration statement or posteffective
         amendment.

                  (4) The Company's agreements with respect to the Warrant
         Shares in this Section will continue in effect regardless of the
         exercise or surrender of this Warrant.

                  (5) Any notices or certificates by the Company to the Holder
         and by the Holder to the Company shall be deemed delivered if in
         writing and delivered personally or sent by certified mail, return
         receipt requested, to the Holder, addressed to the Holder at the
         Holder's address as set forth on the Warrant or stockholder register of
         the Company, or, if the Holder has designated, by notice in writing to
         the Company, any other address, to such other address, and, if to the
         Company, addressed to it at 4801 West 81st Street, Suite 112,
         Bloomington, Minnesota 55437. The Company may change its address by
         written notice to the Holder.

         (K) TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933. The Company may
cause the following legend, or one similar thereto, to be set forth on the
Warrants and on each certificate representing Warrant Shares or any other
security issued or issuable upon exercise of this Warrant not theretofore
distributed to the public or sold to underwriters for distribution to the public
pursuant to Section (j) hereof; unless legal counsel for the Company is of the
opinion as to any such certificate that such legend, or one similar thereto, is
unnecessary:

         "The securities represented by this certificate may not be offered for
         sale, sold or otherwise transferred except pursuant to an effective
         registration statement made under the Securities Act of 1933 (the
         "Act") and under any applicable state securities law, or pursuant to an
         exemption from registration under the Act and under any applicable
         state securities law, the availability of which is to be established to
         the satisfaction of the Company."

         (L)      EXCHANGE PROVISIONS.

                  (1) For purposes of this Section (l), this Warrant shall be
         deemed to represent the same number of Warrants as there are Warrant
         Shares underlying this Warrant. For example, if there are 10,000
         Warrant Shares underlying this Warrant, then for purposes of this
         Section (l) the Holder shall be deemed to hold 10,000 Warrants.

                  (2) For purposes of this Section (l), the following terms
         shall have the following meanings:

                           (A) "Current Market Value of a Warrant Share" shall
                  be the current value of a Warrant Share as determined under
                  Section (c)(1) or (2) hereof except that the time of the
                  determination thereunder shall be the last business day prior
                  to the day the Company receives a notice from the Holder under
                  this Section (l).

                           (B) "Warrant Value" shall mean the Current Market
                  Value of a Warrant Share minus or less the Exercise Price
                  payable under this Warrant as of the close of business on the
                  last business day prior to the day the Company receives a
                  notice from the Holder under this Section (l).

                  (3) The Holder shall have the right to exchange, in a cashless
         transaction, all or part of the Holder's Warrants for Common Shares
         issued by the Company at anytime prior to the Expiration Date of such
         Warrants by providing written notice ("Notice") to the Company.

                  (4) Within 10 days after receipt of such Notice by the
         Company, the Company shall issue the number of Common Shares of the
         Company to the Holder which is determined by dividing the Warrant Value
         of the Warrants being exchanged by the Current Market Value of a
         Warrant Share as of the date the Notice is received by the Company.

                  (5) The Holder shall surrender the Warrant which the Holder is
         exchanging for Common Shares upon receipt thereof. If the entire
         Warrant is being exchanged by the Holder for Common Shares, the Company
         shall cancel the entire Warrant. If less than the entire Warrant is
         being exchanged for Common Shares, the Company shall issue a new
         Warrant to the Holder representing the portion of this Warrant which
         was not exchanged for Common Shares.

         (M) APPLICABLE LAW. This Warrant shall be governed by, and construed in
accordance with, the laws of the state of Colorado.
