Exhibit 4.6
                                                                     -----------

                             INTERCELL CORPORATION
                         REGISTRATION RIGHTS AGREEMENT

     THIS REGISTRATION RIGHTS AGREEMENT ("Agreement") is entered into as of July
1, 1996, by and among INTERCELL CORPORATION, a Colorado corporation ("Company"),
and the subscribers ("Subscribers") to the Company's offering ("Offering") of up
to Ten Million ($10,000,000) of Series B Preferred Stock ("Preferred Stock")
pursuant to the Regulation S Subscription Agreement between the Company and the
Subscribers of even date herewith ("Subscription Agreement").

1.   DEFINITIONS.

     For purposes of this Agreement:

          (a) The terms "register," "registered," and "registration" refer to a
     registration effected by preparing and filing a registration statement or
     similar document in compliance with the Securities Act of 1933 (the "Act"),
     and pursuant to Rule 415 under the Act or any successor rule, and the
     declaration or ordering of effectiveness of such registration statement or
     document;

          (b) For purposes of the Required Registration under Section 2 hereof,
     the term "Registrable Securities" means the Company's Common Stock
     (together with any capital stock issued as a dividend on, in replacement
     of, in exchange for, or otherwise in respect of such Common Stock or issued
     pursuant to Section 17 hereof, the "Common Stock") issuable or issued upon
     conversion of the Preferred Stock and exercise of the Warrants.  For
     purposes of a Demand Registration under Section 3 hereof or a Piggyback
     Registration under Section 4 hereof, the term "Registrable Securities"
     means the Company's Common Stock issuable or issued upon conversion of the
     Preferred Stock and exercise of the Warrants; provided, however, that after
     the expiration of the Restricted Period (as defined in the Subscription
     Agreement), for purposes of Section 3 and Section 4, shares of Common Stock
     obtainable on conversion of the Preferred Stock and exercise of the
     Warrants (in whole or in part) shall not constitute Registrable Securities,
     if those shares of Common Stock may be immediately sold or transferred in
     the U.S. by the Holder free of any restrictive legend, including without
     limitation under Rule 144;

          (c) The number of shares of "Registrable Securities then outstanding"
     shall be determined by the number of shares of Common Stock which have been
     issued or are issuable upon conversion of the Preferred Stock or exercise
     of the Warrants at the time of such determination;

          (d) The term "Holder" means any person owning or having the right to
     acquire Registrable Securities or any permitted assignee thereof;

 
          (e) The terms "Warrant" and "Warrants" refer to the warrant or
     warrants issued to Subscribers as securities in connection with the
     Offering; and

          (f) The term "Due Date" means the date which is ninety (90) days after
     the Last Closing (as defined in the Subscription Agreement) of the
     Offering.

2.   REQUIRED REGISTRATION.

          (a) Within ninety (90) days after the Last Closing (as defined in the
     Subscription Agreement) of the Offering, the Company shall file a
     registration statement ("Registration Statement") on Form S-1, Form SB-2 or
     Form S-3 (if filing on Form S-3 is available to Company) (or other suitable
     form), covering the resale of all shares of Registrable Securities then
     outstanding.

          (b) The Registration Statement shall be prepared as a "shelf"
     registration statement under Rule 415, and shall be maintained effective
     until the distribution described in the Registration Statement is
     completed.  The Company shall use its best efforts to have the Registration
     Statement declared effective as soon as possible after filing.

          (c) The Holders have the right to convert the Preferred Stock into
     Common Stock pursuant to the terms of the Subscription Agreement and the
     Certificate of Designation of Series B Preferred Stock of the Company and
     sell the Common Stock under Regulation S and applicable exemptions until
     such time that the Registration Statement becomes effective.

          (d) Notwithstanding anything to the contrary contained herein, any
     Holder (together with any assignee of its rights) (collectively referred to
     as "Excluded Holders") shall be entitled, by written notice to the Company
     delivered at any time prior to the filing of the Registration Statement
     contemplated by this Section 2, to elect to have the Registrable Securities
     issued or issuable to it excluded from the Registration Statement.  In the
     event a Holder elects not to have its Registrable Securities included in
     the Registration Statement, the Holder shall, nonetheless, and
     notwithstanding anything herein to the contrary, have the right (i) upon
     written notice to the Company from Holders of at least  twenty-five (25%)
     of the Registrable Securities not subject to another registration statement
     then on file with the Securities and Exchange Commission, at any time
     following the expiration of the ninety (90) day period following the Last
     Closing, to cause the Company to effect a Demand Registration (as defined
     in Section 3) registering the Registrable Securities held by such Holders
     on Form S-1 or Form SB-2 or, if available, Form S-3 (or other suitable
     form, subject to the approval of such Holders), and (ii) at any time
     following the Due Date, to have its shares included in any Piggyback
     Registration (as defined in Section 4), in each case in accordance with the
     provisions of Sections 3 and 4 hereof.  In connection with a Demand
     Registration initiated by the Excluded Holders under this Subsection 2(d),
     the Company shall pay all costs and expenses of Demand Registration in
     accordance with Section 9.

 
3.   DEMAND REGISTRATION.

          (a) If the Registration Statement described in Section 2 is not filed
     by the Due Date, or if such Registration Statement is filed timely but is
     not effective within a reasonable time thereafter, the Holders of
     Registrable Securities obtained or obtainable upon conversion of at least
     twenty-five percent (25%) of the shares of the Preferred Stock outstanding
     may notify the Company in writing that they demand that the Company file a
     registration statement under the Act covering the registration of all of
     the Registrable Securities then outstanding on Form S-1 or Form SB-2, or if
     available, Form S-3.  Upon receipt of such notice, the Company shall,
     within ten (10) days, give written notice of such request to all Holders
     and shall, subject to the limitations of subsection 3(b), effect as soon as
     practicable, and in any event within thirty (30) days of the receipt of
     such request, the registration under the Act of all Registrable Securities
     which the Holders request, by notice given to the Company within ten (10)
     days of receipt of the Company's notice, to be registered as expeditiously
     as reasonably possible after the mailing of such notice by the Company (a
     "Demand Registration").

          (b) If the Holders initiating the registration request hereunder
     ("Initiating Holders") intend to distribute the Registrable Securities
     covered by their request by means of an underwriting, they shall so advise
     the Company as a part of their request made pursuant to this Section 3 and
     the Company shall include such information in the written notice referred
     to in subsection 3(a). In such event, the right of any Holder to include
     his Registrable Securities in such registration shall be conditioned upon
     such Holder's participation in such underwriting and the inclusion of such
     Holder's Registrable Securities in the underwriting (unless otherwise
     mutually agreed by a majority in interest of the Initiating Holders and
     such Holder) to the extent provided herein. All Holders proposing to
     distribute their securities through such underwriting shall (together with
     the Company as provided in subsection 7(f)) enter into an underwriting
     agreement in customary form with the underwriter or underwriters selected
     for such underwriting by a majority in interest of the Initiating Holders,
     and reasonably acceptable to the Company; provided that no Holder shall be
     required to make any representations other than with respect to its
     ownership of Registered Securities and its intended method of distribution.

          (c) The Company agrees to include all Registrable Securities held by
     all Holders in such Registration Statement without cutback or reduction. In
     the event the Company breaches its obligation of the preceding sentences,
     any Holders of the Registrable Securities which were not included in such
     Registration Statement shall be entitled to additional Demand Registrations
     for such excluded securities on the same terms as the Demand Registration
     described in this Agreement.  In the event the Company breaches its
     obligations to effect and maintain any registration statement filed
     pursuant to the terms of this Agreement, any Holders of Registrable
     Securities which were not sold because of such breach shall be entitled to
     additional Demand Registrations for such securities which shall be
     maintained until such time as the securities are sold.

 
          (d) The Company is not obligated to effect a demand registration under
     this Section 3 if in the written opinion of counsel to the Company
     reasonably acceptable to the person or persons from whom written request
     for registration has been received (and satisfactory to the Company's
     transfer agent to permit the transfer) that registration under the Act is
     not required for the immediate transfer of the Registrable Securities
     pursuant to Rule 144 or other applicable provision.

          (e) The Company represents that it is eligible to effect the
     registration contemplated hereby on Form S-1 or Form SB-2 and will continue
     to take such actions as are necessary to maintain such eligibility.  The
     Company will use its best efforts to become eligible to use Form S-3 and
     maintain such eligibility.

4.   PIGGYBACK REGISTRATION.

     If the Registration Statement described in Section 2 is not effective by
the Due Date, and no demand for a Demand Registration has been made pursuant to
Section 3, and if (but without any obligation to do so), the Company proposes to
register (including for this purpose a registration effected by the Company for
shareholders other than the Holders) any of its Common Stock under the Act in
connection with the public offering of such securities (other than a
registration relating solely to the sale of securities to participants in a
Company stock plan or a registration on Form S-4 promulgated under the Act or
any successor or similar form registering stock issuable upon a
reclassification, upon a business combination involving an exchange of
securities or upon an exchange offer for securities of the issuer or another
entity), the Company shall, at such time, promptly give each Holder written
notice of such registration. Upon the written request of each Holder given by
fax within ten (10) days after mailing of such notice by the Company, which
request shall state the intended method of disposition of such shares by such
Holder, the Company shall cause to be registered under the Act all of the
Registrable Securities that each such Holder has requested to be registered (a
"Piggyback Registration").

5.   LIMITATION ON OBLIGATIONS TO REGISTER.

          (a) In the case of a Piggyback Registration on an underwritten public
     offering by the Company, if the managing underwriter determines and advises
     in writing that the inclusion in the registration statement of all
     Registrable Securities proposed to be included would interfere with the
     successful marketing of the securities proposed to be registered by the
     Company, then the number of such Registrable Securities to be included in
     the registration statement shall be allocated among all Holders who had
     requested Piggyback Registration, in the proportion that the number of
     Registrable Securities which each such Holder seeks to register bears to
     the total number of Registrable Securities sought to be included by all
     Holders; provided that in no event shall the number of Registrable
     Securities be less than thirty-five percent (35%) pro-rata of the total
     number of shares included in such registration.

          (b) Notwithstanding anything to the contrary herein, the Company shall
     have the right (i) to defer the initial filing or request for acceleration
     of effectiveness of any

 
     Demand Registration or Piggyback Registration or (ii) after effectiveness,
     to suspend effectiveness of any such registration statement, if, in the
     good faith judgment of the board of directors of the Company and upon the
     advice of counsel of the managing underwriter (if any) of the offering,
     such delay in filing or requesting acceleration of effectiveness or such
     suspension of effectiveness is necessary in light of the existence of
     material non-public information (financial or otherwise) concerning the
     Company disclosure of which at the time is not, in the opinion of the board
     of directors of the Company upon the advice of counsel, (A) otherwise
     required and (B) in the best interests of the Company; provided however
     that the Company will use its best efforts to terminate such delay or
     suspension as soon as practicable and, in any event will not delay
     effectiveness of such registration for more than two (2) months from the
     date of the demand or suspend effectiveness for more than twenty (20) days,
     unless it is then engaged in an acquisition that would make such
     registration impracticable, in which case it will use its best efforts to
     eliminate such impracticability as soon as possible.

6.   OBLIGATIONS TO INCREASE AVAILABLE SHARES.

     In the event that the number of shares available under a registration
statement filed pursuant to Section 3 is insufficient to cover all of the
Registrable Securities then outstanding, the Company shall amend that
registration statement, or file a new registration statement, or both, so as to
cover all shares of Registrable Securities then outstanding.  The Company shall
effect such amendment or new registration within sixty (60) days of the date the
registration statement filed under Section 3 is insufficient to cover all the
shares of Registrable Securities then outstanding.  Any Registration Statement
filed hereunder shall, to the extent permissible by the Rules of the Securities
and Exchange Commission ("SEC"), state that, in accordance with Rule 416 under
the Act, such Registration Statement also covers such indeterminate numbers of
additional shares of Common Stock as may become issuable upon conversion of the
Preferred Stock to prevent dilution resulting from stock changes or by reason of
changes in the conversion price in accordance with the terms thereof.

7.   OBLIGATIONS OF THE COMPANY.

     Whenever required under this Agreement to effect the registration of any
Registrable Securities, the Company shall, as expeditiously as reasonably
possible:

          (a) Prepare and file with the SEC a registration statement with
     respect to such Registrable Securities and use its best efforts to cause
     such registration statement to become effective.

          (b) Prepare and file with the SEC such amendments and supplements to
     such registration statement and the prospectus used in connection with such
     registration statement as may be necessary to comply with the provisions of
     the Act with respect to the disposition of all securities covered by such
     registration statement.

          (c) With respect to any Demand Registration, use best efforts to keep
     such registration statement effective until the Holders of Registrable
     Securities covered by

 
     such registration statement have completed the distribution described in
     the registration statement.

          (d) Furnish to the Holders (i) such numbers of copies of a prospectus,
     including a preliminary prospectus, in conformity with the requirements of
     the Act, and such other documents as they may reasonably request in order
     to facilitate the disposition of Registrable Securities owned by them and
     (ii) copies of all correspondence to or with the SEC.  Each Holder shall be
     furnished with copies of drafts of all filings (including amendments and
     supplements) prior to filing and given sufficient time to provide comments
     thereon.

          (e) Use its best efforts to register and qualify the securities
     covered by such registration statement under such other securities or Blue
     Sky laws of such jurisdictions as shall be reasonably requested by the
     Holders of the Registrable Securities covered by such registration
     statement, provided that the Company shall not be required in connection
     therewith or as a condition thereto to qualify to do business or to file a
     general consent to service of process in any such states or jurisdictions.

          (f) In the event of any underwritten public offering, enter into and
     perform its obligations under an underwriting agreement, in usual and
     customary form, with the managing underwriter of such offering. Each Holder
     participating in such underwriting shall also enter into and perform its
     obligations under such an agreement.

          (g) Notify each Holder of Registrable Securities covered by such
     registration statement at any time when a prospectus relating thereto is
     required to be delivered under the Act upon the happening of any event as a
     result of which the prospectus included in such registration statement, as
     then in effect, includes an untrue statement of a material fact or omits to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in the light of the circumstances
     then existing.

          (h) Furnish, at the request of any Holder whose shares are being
     registered pursuant to this Agreement, on the date that such Registrable
     Securities are delivered to the underwriters for sale in connection with a
     registration pursuant to this Agreement, if such securities are being sold
     through underwriters, or, if such securities are not being sold through
     underwriters, on the date that the registration statement with respect to
     such securities becomes effective, (i) an opinion, dated such date, of the
     counsel representing the Company for the purposes of such registration, in
     form and substance as is customarily given to underwriters in an
     underwritten public offering, addressed to the underwriters, if any, and to
     the Holders requesting registration of Registrable Securities and (ii) a
     letter dated such date, from the independent certified public accountants
     of the Company, in form and substance as is customarily given by
     independent certified public accountants to underwriters in an underwritten
     public offering, addressed to the underwriters, if any, and to the Holders
     requesting registration of Registrable Securities.

          (i) Maintain the listing of the Common Stock on the OTC Bulletin Board
     or other automated quotation system or a national securities exchange.

 
8.   FURNISH INFORMATION.

     It shall be a condition precedent to the obligations of the Company to take
any action pursuant to this Agreement that the selling Holders shall furnish to
the Company such information regarding themselves, the Registrable Securities
held by them, and the intended method of disposition of such securities as shall
be required to effect the registration of their Registrable Securities or to
determine that registration is not required pursuant to Rule 144 or other
applicable provision of the Act.

9.   EXPENSES OF REQUIRED OR DEMAND REGISTRATION.

     All expenses other than underwriting discounts and commissions incurred in
connection with registrations, filings or qualifications pursuant to Sections 2
or 3, including (without limitation) all registration, filing and qualification
fees, printers' and accounting fees, fees and disbursements of counsel for the
Company, and including the reasonable fees and disbursements incurred of only
one counsel for the selling Holders shall be borne by the Company; provided,
however, that the Company shall not be required to pay for any expenses of any
registration proceeding begun pursuant to Sections 2 or 3 if the registration
request is subsequently withdrawn at the request of the Holders of a majority of
the Registrable Securities to be registered (in which case all Holders who had
requested such registration shall bear such expenses); provided further,
however, that if at the time of such withdrawal, the Holders have learned of a
material adverse change in the condition, business, or prospects of the Company
from that known to the Holders at the time of their request, then the Holders
shall not be required to pay any of such expenses and shall retain their rights
pursuant to Sections 2 and 3.

10.  EXPENSES OF COMPANY REGISTRATION.

     The Company shall bear and pay all expenses incurred in connection with any
registration, filing or qualification of Registrable Securities with respect to
the registrations pursuant to Section 4 for each Holder, including (without
limitation) all registration, filing, and qualification fees, printers and
accounting fees relating or apportionable thereto (and including the reasonable
fees and disbursements incurred of only one counsel for the selling Holders
selected by them), but excluding underwriting discounts and commissions relating
to Registrable Securities.

11.  INDEMNIFICATION.

     In the event any Registrable Securities are included in a registration
statement under this Agreement:

          (a) To the extent permitted by law, the Company will indemnify and
     hold harmless each "Holder Indemnified Persons" (defined for purposes of
     this Section 11 as each Holder, the officers and directors of each Holder
     acting in their capacity as such, any underwriter (as defined in the Act)
     for such Holder and each person, if any, who controls such Holder or
     underwriter within the meaning of the Act or the Securities Exchange Act of
     1934, as amended (the "1934 Act")), against any losses, claims,

 
     damages, expenses, or liabilities (joint or several) (hereinafter referred
     to singularly as "Loss" and collectively as "Losses") to which they may
     become subject under the Act, the 1934 Act or other federal or state law,
     insofar as such Losses (or actions in respect thereof) arise out of or are
     based upon any of the following statements, omissions or violations
     (collectively a "Violation"): (i) any untrue statement, or alleged untrue
     statement, of a material fact contained in such registration statement,
     including any preliminary prospectus or final prospectus contained therein
     or any amendments or supplements thereto, (ii) the omission, or alleged
     omission, to state therein a material fact required to be stated therein,
     or necessary to make the statements therein not misleading, or (iii) any
     violation by the Company of the Act, the 1934 Act, any state securities law
     or any rule or regulation promulgated under the Act, the 1934 Act or any
     state securities law; and the Company will reimburse each such Holder
     Indemnified Person  for any legal or other expenses reasonably incurred by
     them in connection with investigating or defending any such Loss or action;
     provided, however, that the indemnity agreement contained in this
     subsection 11(a) shall not apply to amounts paid in settlement of any such
     Loss or action if such settlement is effected without the consent of the
     Company (which consent shall not be unreasonably withheld), nor shall the
     Company be liable in any such case to an Indemnified Person for any such
     Loss or action to the extent that it arises out of or is based upon a
     Violation which occurs (i) in reliance upon and in conformity with written
     information furnished expressly for use in connection with such
     registration by such Holder Indemnified Person or (ii) based upon a
     prospectus which included a Violation after the Company has advised such
     Indemnified Person not to sell pursuant to such prospectus, and has made
     available to such Indemnified Person an amended or supplemental prospectus
     that corrects such Violation.

          (b) To the extent permitted by law, each selling Holder will indemnify
     and hold harmless the "Company Indemnified Persons" (defined for the
     purpose of this Section 11 as the Company, each of its directors in their
     capacity as such, each of its officers who have signed the registration
     statement in their capacity as such, each person, if any, who controls the
     Company within the meaning of the Act in their capacity as such, any
     underwriter and any other Holder Indemnified Person selling securities in
     such registration statement), against any Loss (joint or several) to which
     the Company or any such director, officer, controlling person, or
     underwriter or controlling person, or other such Holder Indemnified Person
     may become subject, under the Act, the 1934 Act or other federal or state
     law, insofar as such Loss (or actions in respect thereto) arises out of or
     is based upon any Violation, in each case to the extent (and only to the
     extent) that such Violation occurs in reliance upon and in conformity with
     written information furnished by such Holder expressly for use in
     connection with such registration; and each such Holder will reimburse any
     legal or other expenses reasonably incurred by the Company and any such
     Company Indemnified Person in connection with investigating or defending
     any such Loss or action; provided, however, that the indemnity agreement
     contained in this subsection 11(b) shall not apply to amounts paid in
     settlement of any such Loss or action if such settlement is effected
     without the consent of the Holder, which consent shall not be unreasonably
     withheld; provided, that, in no event shall any indemnity under this
     subsection 11(b) exceed the gross proceeds from the offering received by
     such Holder.

 
         (c) Promptly after receipt by an indemnified party under this Section
     11 of notice of the commencement of any action (including any governmental
     action), such indemnified party will, if a claim in respect thereof is to
     be made against any indemnifying party under this Section 11, deliver to
     the indemnifying party a written notice of the commencement thereof and the
     indemnifying party shall have the right to participate in, and, to the
     extent the indemnifying party so desires, jointly with any other
     indemnifying party similarly noticed, to assume the defense thereof with
     counsel mutually satisfactory to the parties; provided, however, that an
     indemnified party shall have the right to retain its own counsel, with the
     reasonably incurred fees and expenses to be paid by the indemnifying party,
     if representation of such indemnified party by the counsel retained by the
     indemnifying party would be inappropriate due to actual or potential
     differing interests between such indemnified party and any other party
     represented by such counsel in such proceeding. The failure to deliver
     written notice to the indemnifying party within a reasonable time of the
     commencement of any such action, if prejudicial to its ability to defend
     such action, shall relieve such indemnifying party of any liability to the
     indemnified party under this Section 11, but the omission so to deliver
     written notice to the indemnifying party will not relieve it of any
     liability that it may have to any indemnified party otherwise than under
     this Section 11 to the extent it is prejudicial.

          (d) The obligations of the Company and Holders under this Section 11
     shall survive the redemption and conversion, if any, of the Preferred
     Stock, the completion of any offering of Registrable Securities in a
     registration statement under this Agreement, and otherwise.

12.  REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934.

     With a view to making available to the Holders the benefits of Rule 144
promulgated under the Act and any other rule or regulation of the SEC that may
at any time permit a Holder to sell securities of the Company to the public
without registration, the Company agrees to:

          (a) make and keep public information available, as those terms are
     understood and defined in SEC Rule 144, at all times;

          (b) file with the SEC in a timely manner all reports and other
     documents required of the Company under the Act and the 1934 Act; and

          (c) furnish to any Holder, so long as the Holder owns any Registrable
     Securities, forthwith upon request (i) a written statement by the Company,
     if true, that it has complied with the reporting requirements of SEC Rule
     144 (at any time after ninety (90) days after the effective date of the
     first registration statement filed by the Company), the Act and the 1934
     Act, (ii) a copy of the most recent annual or quarterly report of the
     Company and such other reports and documents so filed by the Company, and
     (iii) such other information as may be reasonably requested in availing any
     Holder of any rule or regulation of the SEC which permits the selling of
     any such securities without registration.

 
13.  AMENDMENT OF REGISTRATION RIGHTS.

     Any provision of this Agreement may be amended and the observance thereof
may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company,
and the holders of a majority of the Registrable Securities then outstanding.
Any amendment or waiver effected in accordance with this paragraph shall be
binding upon each Holder, each future Holder, and the Company; provided,
however, that no amendment or waiver that materially and adversely affects the
rights of any Holder shall be effective against such Holder unless such Holder
agrees thereto.

14.  NOTICES.

17.  PAYMENTS FOR FAILURE TO REGISTER OR FAILURE TO LIST.

     If the Registration Statement required under Section 2 hereof is not filed
on or prior to ninety (90) days after the Last Closing or if a registration
statement filed pursuant to Section 3 is not effective within ninety (90) days
of demand, or if the Company fails to respond to any request for information
from the SEC related to such Registration Statement within fifteen (15) days of
such request, then the Company shall pay to all Holders of outstanding Preferred
Stock an aggregate amount equal to two percent (2%) per month of the aggregate
amount of Preferred Stock sold in the Offering, compounded monthly, and accruing
daily, payable in Common Stock, which Common Stock shall also be deemed
"Registrable Securities" hereunder.  If, the Company is not eligible to effect a
Registration under Form S-1 or SB-2 or S-3, or other appropriate registration
statement, at the time of a Demand Registration under the terms of this
agreement solely through the act or failure to act by the Company, and not due
to a change in statute or regulation or other fact circumstance not under the
Company's control, then the Company shall pay to all Holders of outstanding
Preferred Stock an aggregate penalty equal to the amount of the Conversion
Default Payment ("Conversion Default Payment") set forth in Section 7.6 of the
Regulation S Subscription Agreement between the Company and the Subscribers
("Subscription Agreement") for each day beyond sixty (60) days of the receipt of
a request for a Demand Registration until such registration is complete.  If, on
the date (the "Conversion Eligibility Date") that Preferred Stock becomes
eligible for conversion into Common Stock or the Warrants are exercisable, the
Common Stock is not listed on the OTC Bulletin Board or other national stock
exchange or automated quotation system, then the Company shall pay to all
Holders of outstanding Preferred Stock that are eligible for immediate
conversion and to all Holders of unexercised Warrants a penalty equal to the
amount of the Conversion Default Payment ("Conversion Default Payment") set
forth in Section 7.6 of the Regulation S Subscription Agreement between the
Company and the Subscribers ("Subscription Agreement") for each day beyond the
Conversion Eligibility Date until such listing is complete.
