COMMON STOCK AND WARRANT PRIVATE PLACEMENT

     On September 7, 1999, the Company completed a $7.2 million private
placement of 981,119 units with each consisting of one share of the Company's
common stock, par value $0.001 (the "Common Stock") and one warrant to purchase
0.35 shares of Common Stock. The offering was made to "accredited investors"
only, as defined in Rule 501(a) of Regulation D. The investors include the
following officers and directors of the Company: Billy D. Prim, Craig J.
Duchossois, Andrew J. Filipowski, Mark Castaneda, Steven D. Devick, Richard A.
Brenner and Jerald D. Shadley, who in the aggregate purchased 438,747 of the
981,119 units sold. The price per unit was $7.375 per share, which was the
closing price of the Company's Common Stock on September 3, 1999, the final
trading day prior to the consummation of the offering. The warrants may be
exercised at a price equal to $8.48 per share at any time prior to September 7,
2004. The Company used the proceeds of this offering to pay certain expenses
associated with the offering and repay indebtedness. Lunn Partners, LLC,
received a placement fee of $120,000 in connection with this offering.

     Pursuant to the terms of the offering, the Company is required to file a
registration statement by November 5, 1999 to register the resale of the shares
issued in the offering and any shares issued upon the exercise of the warrants.
This registration statement will also cover the shares of Common Stock required
to be registered pursuant to the terms of the private offering described below.

CONVERTIBLE NOTE AND WARRANT PRIVATE PLACEMENT

     On September 22, 1999, the Company entered into an agreement with two
institutional investors (the "Investors") to issue $7,000,000 of 5% Convertible
Notes (the "Convertible Notes") and warrants to purchase Common Stock (the
"Warrants") in a private placement (the "Convertible Note Offering"). The
Company has authorized and reserved for issuance upon the conversion of the
Convertible Notes and exercise of the Warrants shares of its Common Stock equal
to 200% of the total number of shares issuable upon conversion of the
Convertible Notes as of the closing date plus the number of Shares issuable upon
the exercise of the warrants. The Convertible Notes have a two year term and
bear interest at 5% per annum, payable in full in cash at maturity. The Company
may require the holders of the Convertible Notes to convert the principal and
interest on the Convertible Notes into Common Stock subject to certain
conditions, or upon the occurrence of certain events, the holder may convert the
principal and interest on the Convertible Notes into Common Stock. The
Convertible Notes convert at the lesser of a fixed conversion price or 95% of
the Weighted Average Price of the Common Stock at the time of conversion. The
Company will use the $7.0 million of proceeds from this offering to pay expenses
associated with the offering, reduce indebtedness, acquire assets and for
working capital and general corporate purposes. Upon the repayment of $2.6
million of the indebtedness of its wholly owned subsidiary, USA Leasing, L.L.C.
to Bank of America, the bank will release Billy D. Prim, Andrew J. Filipowski,
Craig J. Duchossois and Peer Pedersen from their $650,000 guarantees of such
indebtedness.

     The following is a summary of the material terms of the Convertible Note
Offering, which terms are qualified by reference to the full text of the
underlying documents which are filed as exhibits to this Form 8-K. The
underlying documents for the Convertible Note Offering are a securities purchase
agreement ("Securities Purchase Agreement") and a registration rights

                                      -2-
<PAGE>

agreement ("Registration Rights Agreement") by and between the Company and the
Investors and a convertible note ("Convertible Note") made by the Company all
filed as exhibits to this Form 8-K. In addition, a Form of Warrant is also filed
as an exhibit to this Form 8-K. All capitalized terms used but otherwise not
defined herein have the meanings ascribed to those terms in the transaction
documents.

THE CLOSINGS. At the initial closing of the transaction (the "Initial Closing"),
the Investors purchased Convertible Notes in the aggregate principal amount of
$7,000,000. The Company also issued the Investors warrants to purchase in the
aggregate 332,203 shares of Common Stock. The warrants are exercisable for five
years at an exercise price of $8.48 per share. In the future, the Company may
also require the Investors to purchase in up to two additional closings
Convertible Notes in an amount equal in the aggregate to at least $1,000,000 but
not more than $4,900,000 if certain conditions are met. The Investors'
obligation to purchase additional Convertible Notes is conditioned upon (a) the
effectiveness of a registration statement with the Securities and Exchange
Commission ("SEC") covering the resale of the shares of Common Stock issuable
upon conversion or exercise of the Convertible Notes and the Warrant issued at
the Initial Closing and shares to be issued upon the conversion of any notes or
exercise of warrants issued at any subsequent closing, (b) the Company's Common
Stock is listed with The Nasdaq Stock Market ("Nasdaq") or the New York Stock
Exchange, (c) the Company shall not have consummated a Change of Control or
defaulted under the terms of the Securities Purchase Agreement or Convertible
Notes, (d) the stock price of the Common Stock shall be at least $8.50 per share
(adjusted for stock splits, combinations and recapitalizations effected after
the closing date), (e) the Company shall have converted at least $1,750,000 of
the balance of the initial Convertible Note into common stock, (f) the Company
shall have received stockholder approval of the issuance of the Conversion
Shares and Warrant Shares as required by the Securities Purchase Agreement and
(h) the satisfaction of certain other terms and conditions, all as more fully
set forth in the Securities Purchase Agreement.

CONVERSION. The principal and accrued interest on the Convertible Notes is
convertible, in whole or in part, by dividing the amount to be converted (the
"Conversion Amount") by the lesser of (i) a "fixed conversion price", or (ii) a
"variable conversion price". The fixed conversion price shall equal $20.00 per
share. The variable conversion price shall equal 95% of the dollar volume-
weighted average price for the Common Stock on Nasdaq (as reported by Bloomberg
Financial Markets through its "Volume at Price" function) on the conversion date
(the "Variable Conversion Price"). For a period of 18 months, the Convertible
Notes may not be converted unless: (a) the Company, subject to certain
exceptions, requires conversion, (b) the Common Stock is not listed or quoted on
Nasdaq or The New York Stock Exchange ("NYSE"), or has been suspended from
trading for more than one day, (c) a Change of Control or Triggering Event or
Event of Default shall have occurred or be pending, (d) the Company issues or
sells or is deemed to have issued or sold any Convertible Securities that are
convertible into or exercisable or exchangeable for shares of Common Stock at a
variable price, (e) the Company fails to pay any redemption amount or issue any
shares upon a conversion of the Convertible Notes or exercise of the Warrants,
(f) the Company issues additional shares of Common Stock or securities
convertible into Common Stock other than (i) up to 500,000 shares issuable in
connection with acquisitions at a value per share equal or greater than the
market price of the Common Stock, (ii) shares issuable upon the exercise of
employee,

                                      -3-
<PAGE>

director and distributor options and outstanding warrants, or (g) with respect
to the conversion of up to 25% of the total amount outstanding on the
Convertible Notes, if on or after the date which is 15 months after the Initial
Closing at least 75% of the aggregate original principal amounts of all Notes
remains outstanding. Upon the occurrence of any events in (b) through (g) above,
the holder of the Convertible Note may elect to convert all or any portion of
the Note into Common Stock. "Triggering Events" include the Company's: (a)
failure to register the shares issuable upon conversion of the Convertible Notes
or Warrants within 155 days after the Initial Closing, (b) failure to maintain
the effectiveness of such registration statement, (c) Common Stock not being
listed or quoted on Nasdaq or the NYSE, (d) failure to issue any Common Stock
upon conversion as required, (e) inability to issue any shares of Common Stock
as a result of restrictions on the issuance of shares under Nasdaq rules or (f)
failure to seek the consent of its stockholders to the issuance of Common Stock
upon conversion of the Convertible Notes and Warrants before January 31, 2000.
Upon the occurrence of a Triggering Event, in addition to converting the balance
of their Note into Common Stock, the holders of Convertible Notes could require
the Company to redeem all of the remaining principal and interest at a price
equal to 120% of the outstanding balance. In the event that the Company or its
transfer agent do not timely effect a conversion of the Convertible Notes, the
Company is subject to certain liquidated damage penalties including reductions
in the Variable Conversion Price, adjustments to the applicable fixed conversion
price and certain other penalties as more fully described in the Convertible
Note.

The holders of the Convertible Notes are prohibited from converting their notes
if after giving effect to such conversion the holder would beneficially own in
excess of 4.99% of the outstanding shares of Common Stock of the Company
following such conversion. In addition, the Convertible Notes are subordinate
subject to certain exceptions, to up to $25 million of the Company's
indebtedness to Bank of America.

The following risks are associated with Convertible Note conversions:

     .    Because the Variable Conversion Price of the Convertible Notes is a
          function of the market price of the Common Stock upon conversion, the
          lower the price of the Common Stock at the time the holder converts,
          the greater the number of shares of Common Stock received upon
          conversion;

     .    To the extent that Common Stock received upon conversion is sold into
          the market, and disregarding the manner in which such shares are sold
          as well as any other factors such as reactions to the Company's
          operating results and general market conditions which may be operative
          in the market at such time, such sales may cause a decrease in the
          market price of the Common Stock, which in turn, relative to
          additional conversions of the Convertible Notes and Warrants, would
          reduce the Variable Conversion Price and increase the number of shares
          of Common Stock issued upon conversion of the Convertible Notes and
          available for sale into the market for the Common Stock;

     .    Short sales of the Common Stock may accompany conversions and sales of
          Common Stock from conversions, which sales in the

                                      -4-
<PAGE>

          aggregate could cause downward pressure upon the price of the Common
          Stock, excluding the effect of other market factors possibly operative
          at the time; and

     .    Conversions of the Convertible Notes may result in substantial
          dilution of the interests of the other holders of Common Stock. In
          this regard, the ownership limitation which prohibits the purchasers
          from owning more than 4.99% of the Common Stock of the Company only
          applies to shares of Common Stock held at one time and does not
          prevent purchasers from converting and selling some of their holdings
          and then later converting the rest of their holdings.

     .    The Common Stock could be delisted by Nasdaq in the event that the
          Company's stock price decreases below the $1 minimum bid price as
          required by Nasdaq or the Company otherwise fails to satisfy the
          minimum listing requirements of Nasdaq. In such an event, should such
          a delisting extend for five or more consecutive trading days, a
          Triggering Event would occur and the holders of the Convertible Notes
          could require the Company to redeem the  outstanding shares of
          Convertible Notes.

INTEREST. The outstanding principal balance on the Convertible Notes bears
interest at 5% per annum.  Interest accrues until paid in full.  After and
during the continuance of an event of default, the Convertible Notes bear a
default rate of interest equal to 18%.

REGISTRATION OF SHARES; POSSIBLE ADJUSTMENT OF CONVERSION PRICE AND EXERCISE
PRICE. The Company is required to register with the SEC the resale of at least
200% of the number of shares of Common Stock issuable upon conversion of the
Convertible Notes and exercise of the Warrants and conversion of any Convertible
Notes or exercise of any warrants to be issued in any subsequent closing. The
number of shares is based on the Conversion Price at the time of the filing of
the registration statement. The Company has agreed to use its best efforts to
file the initial registration statement as soon as possible but no later than 60
days after the Initial Closing and have the registration statement declared
effective by the SEC no later than 135 days after the initial closing (the
"Scheduled Effective Date"). In addition, during the period the registration
statement is effective, the Company has agreed that the resale of at least 150%
of the shares issuable upon conversion of the Convertible Notes and the resale
of at least 100% of the shares of Common Stock issuable upon exercise of the
warrants will remain registered under the registration statement.

OTHER TERMS. The transaction documents relating to the Convertible Notes also
contain certain other representations, warranties, agreements, and
indemnification obligations of the Company.  The operative  agreements also
contain (i) a right of first refusal in favor of the investors which applies to
certain private equity financings of the Company and (ii) prohibit the Company
from entering into certain related party transactions.  The Convertible Notes
and Warrants are also subject to antidilution provisions which are triggered in
the event of certain stock splits, recapitalizations, or other dilutive
transactions, as well as issuances of Common

                                      -5-
<PAGE>

Stock at a price below the market price or the fixed conversion price in effect,
or the issuance of warrants, options, rights, or convertible securities which
have an exercise price or conversion price less than the market price on the
date of issuance or the fixed conversion price, other than for certain
previously outstanding securities and certain excluded securities. In the event
that the Company issues securities in the future which have a conversion price
or exercise price which varies with the market price and the terms of such
variable price are more favorable than the Variable Conversion Price in the
Convertible Notes, the purchasers may elect to substitute the more favorable
variable price when making conversions of the Convertible Notes.

WARRANTS. In connection with the closings of the Convertible Notes, the Company
will issue warrants to purchase Common Stock which at the time of issuance has a
market value (as determined using the average of the closing share price for the
ten days prior to the closing) equal to 35% of the principal value of the
Convertible Notes. The warrants may be exercised over five years. At the Initial
Closing, the Company will issue the Investors warrants to purchase in the
aggregate 332,203 shares of Common Stock at an exercise price of $8.48 per
share. The warrants expire on September 23, 2004. The warrants are subject to
certain antidilution provisions in the event the Company sells Common Stock or
securities convertible or exercisable into Common Stock at a price less than the
exercise price of such warrants or the market price of the Common Stock.

BISON VALVE ACQUISITION.

On September 17, 1999, the Company completed the acquisition of certain assets
related to the overfill protection device ("OPD") developed, manufactured for
and marketed by Bison Valve, L.L.C. The purchase price included $1.123 million
in cash, the offset of $732,190.23 in principal and accrued interest due to the
Company under a convertible note and a ten-year warrant to purchase 100,000
shares of the Company's Common Stock at an exercise price equal to $7.40 per
share. The acquired assets included OPD inventories, molds, dies, and all
intellectual property relating to the OPD developed by Bison Valve and its
manager, Michael A. Waters, which includes two patent applications on the OPD.
The net book value of the assets acquired and the purchase price paid did not
exceed 10 percent of the book value of the Company's assets nor does the
acquisition involve a business which is significant as defined in Rule 11-01 of
Regulation S-X.

An OPD is a device which fits inside of the valve of a grill cylinder and
prevents the overfilling of the cylinder by automatically cutting off the flow
of liquid propane gas after the amount in the cylinder reaches a certain level.
Current guidelines issued by the National Fire Protection Association require
that all grill cylinders produced or recertified after September 30, 1998, and
all grill cylinders refilled after April 1, 2002, must be fitted with an OPD.
The Company believes there are 50 million grill cylinders in use today that must
be upgraded or replaced with an OPD-equipped cylinder.

                         REGISTRATION RIGHTS AGREEMENT


     REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of September 7,
1999, by and among BLUE RHINO CORPORATION, a Delaware corporation with
headquarters located at 104 Cambridge Plaza Drive, Winston-Salem, North Carolina
27104 (the "Company"), and the undersigned Buyers (individually a "Buyer" and
collectively the "Buyers").

     WHEREAS:

     A.   In connection with the private offering of  approximately $7.2 million
of shares of the Company's common stock on September 7, 1999 (the "Offering"),
the Company has agreed to issue and sell to the Buyers (i) 981,119 shares of the
Company's common stock, par value $.001 per share (the "Common Stock") and (ii)
warrants to purchase 343,383 shares of Common Stock  (the "Initial Warrants"
and, as exercised, the "Initial Warrant Shares").

     B.   To induce the Buyers to participate in the Offering, the Company has
agreed to provide certain registration rights under the Securities Act of 1933,
as amended, and the rules and regulations thereunder, or any similar successor
statute (collectively, the "1933 Act"), and applicable state securities laws.

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and each of the Buyers
hereby agree as follows:

     1.   DEFINITIONS.
          -----------

          As used in this Agreement, the following terms shall have the
following meanings:

          a.   "Investor" means a Buyer and any transferee or assignee thereof
to whom a Buyer assigns its rights under this Agreement and who agrees to become
bound by the provisions of this Agreement in accordance with Section 9.

          b.   "Person" means a corporation, a limited liability company, an
association, a partnership, an organization, a business, an individual, a
governmental or political subdivision thereof or a governmental agency.

          c.   "Register," "registered," and "registration" refer to a
registration effected by preparing and filing one or more Registration
Statements (as defined below) in compliance with the 1933 Act and pursuant to
Rule 415 under the 1933 Act or any successor rule providing for offering
securities on a continuous or delayed basis ("Rule 415"), and the declaration or
ordering of effectiveness of such Registration Statement(s) by the United States
Securities and Exchange Commission (the "SEC").
<PAGE>

          d.   "Registrable Securities" means (i) the Common Stock purchased in
the Offering, (ii) the Common Stock issued or issuable upon the exercise of the
Warrants (the "Warrant Shares"), and (iii) any shares of capital stock issued or
issuable with respect to the Common Stock or Warrant Shares as a result of any
stock split, stock dividend, recapitalization, exchange or similar event or
otherwise.

          e.   "Registration Statement" means a registration statement or
registration statements of the Company filed under the 1933 Act covering the
Registrable Securities.

          f.   "Filing Deadline" has the meaning ascribed to it in Section
2(a)(i).

          g.   "Effectiveness Deadline" means the Initial Effectiveness Deadline
or the Additional Effectiveness Deadline, as applicable.

     2.   REGISTRATION.
          ------------

          a.   Mandatory Registration.  The Company shall prepare, and, as soon
               ----------------------
as practicable, but in no event later than 60 days after the Closing Date (as
defined in the Securities Purchase Agreement) (the "Filing Deadline") file with
the SEC an Registration Statement or Registration Statements (as necessary) on
Form S-3 covering the resale of all of the Registrable Securities.  In the event
that Form S-3 is unavailable for such a registration, the Company shall use such
other form as is available for such a registration, subject to the provisions of
Section 2(e).  Any first Registration Statement prepared pursuant hereto shall
register for resale at least that number of shares of Common Stock equal to the
sum of the number of  Shares of Common Stock, plus the number of Warrant Shares
issuable upon exercise of all of the Warrants (without regard to any limitations
on exercise) as of the date immediately preceding the date the Registration
Statement is initially filed with the SEC, subject to adjustment as provided in
Section 3(b).  The Company shall use its best efforts to cause such Registration
Statement to be declared effective by the SEC as soon as possible, but in no
event later than 120 days after the Initial Closing Date (the "Initial
Effectiveness Deadline").

          b.   Piggy-Back Registrations.  If at any time prior to the expiration
               ------------------------
of the Registration Period (as hereinafter defined), the number of shares of
Common Stock available for sale under a Registration Statement is insufficient
(as that term is used in Section 2(g)) to cover all of the Registrable
Securities and the Company proposes to file with the SEC a Registration
Statement relating to an offering for its own account or the account of others
under the 1933 Act of any of its securities (other than on Form S-4 or Form S-8
(or their equivalents at such time) relating to securities to be issued solely
in connection with any acquisition of any entity or business or equity
securities issuable in connection with stock option or other employee benefit
plans and other than in connection with the Company's Distributor Option Plan)
the Company shall promptly send to each Investor who is entitled to registration
rights under this Section 2(b) written notice of the Company's intention to file
a Registration Statement and of such Investor's rights under this Section 2(b)
and, if within twenty (20) days after receipt of such notice, such Investor
shall so request in writing, the

                                      -2-
<PAGE>

Company shall include in such Registration Statement all or any part of the
Registrable Securities such Investor requests to be registered, subject to the
priorities set forth in Section 2(b) below. No right to registration of
Registrable Securities under this Section 2(b) shall be construed to limit any
registration required under Section 2(a). The obligations of the Company under
this Section 2(b) may be waived by Investors holding a majority of the
Registrable Securities. If an offering in connection with which an Investor is
entitled to registration under this Section 2(b) is an underwritten offering,
then each Investor whose Registrable Securities are included in such
Registration Statement shall, unless otherwise agreed by the Company, offer and
sell such Registrable Securities in an underwritten offering using the same
underwriter or underwriters and, subject to the provisions of this Agreement, on
the same terms and conditions as other shares of Common Stock included in such
underwritten offering. If a registration pursuant to this Section 2(b) is to be
an underwritten public offering and the managing underwriter(s) advise the
Company in writing, that in their reasonable good faith opinion, marketing or
other factors dictate that a limitation on the number of shares of Common Stock
which may be included in the Registration Statement is necessary to facilitate
and not adversely affect the proposed offering, then the Company shall include
in such registration: (1) first, all securities the Company proposes to sell for
its own account, (2) second, up to the full number of securities proposed to be
registered for the account of the holders of securities entitled to inclusion of
their securities in the Registration Statement by reason of demand registration
rights, (3) third, the securities requested to be registered by the holders of
securities entitled to participate in the registration, as of the date hereof,
pursuant to the Amended and Restated Registration Rights Agreement, as amended
and (4) fourth, the securities requested to be registered by the Investors and
other holders of securities entitled to participate in the registration, as of
the date hereof, drawn from them pro rata based on the number each has requested
to be included in such registration including those holders of registration
rights which may be granted by the Company in connection with any sale of
Convertible Notes and Warrants which is contemplated as of the date of this
Agreement.

          c.   Allocation of Registrable Securities.  The initial number of
               ------------------------------------
Registrable Securities included in any Registration Statement and each increase
in the number of Registrable Securities included therein shall be allocated pro
rata among the Investors based on the number of Registrable Securities held by
each Investor at the time the Registration Statement covering such initial
number of Registrable Securities or increase thereof is declared effective by
the SEC.  In the event that an Investor sells or otherwise transfers any of such
Person's Registrable Securities, each transferee shall be allocated a pro rata
portion of the then remaining number of Registrable Securities included in such
Registration Statement for such transferor.  Any shares of Common Stock included
in a Registration Statement and which remain allocated to any Person which
ceases to hold any Registrable Securities covered by such Registration Statement
shall be allocated to the remaining Investors, pro rata based on the number of
Registrable Securities then held by such Investors which are covered by such
Registration Statement.

     3.   RELATED OBLIGATIONS.
          -------------------

                                      -3-
<PAGE>

     At such time as the Company is obligated to file a Registration Statement
with the SEC pursuant to Section 2(a), the Company will use its best efforts to
effect the registration of the Registrable Securities in accordance with the
intended method of disposition thereof and, pursuant thereto, the Company shall
have the following obligations:

          a.   The Company shall promptly prepare and file with the SEC a
Registration Statement with respect to the Registrable Securities (but in no
event later than the Filing Deadline) and use its best efforts to cause such
Registration Statement relating to the Registrable Securities to become
effective as soon as practicable after such filing (but in no event later than
the applicable Effectiveness Deadline).  The Company shall keep each
Registration Statement effective pursuant to Rule 415 at all times until the
earlier of (i) the date as of which the Investors may sell all of the
Registrable Securities covered by such Registration Statement without
restriction pursuant to Rule 144(k) promulgated under the 1933 Act (or successor
thereto) or (ii) the date on which the Investors shall have sold all the
Registrable Securities covered by such Registration Statement (the "Registration
Period"), which Registration Statement (including any amendments or supplements
thereto and prospectuses contained therein) shall not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein, or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading.  The term "best efforts"
as used in the first sentence of this Section 3(a) shall mean, among other
things, that the Company shall submit to the SEC, within two business days after
the Company learns that no review of a particular Registration Statement will be
made by the staff of the SEC or that the staff has no further comments on the
Registration Statement, as the case may be, a request for acceleration of
effectiveness of such Registration Statement to a time and date not later than
two business days after the submission of such request.

          b.   The Company shall prepare and file with the SEC such amendments
(including post-effective amendments) and supplements to a Registration
Statement and the prospectus used in connection with such Registration
Statement, which prospectus is to be filed pursuant to Rule 424 promulgated
under the 1933 Act, as may be necessary to keep such Registration Statement
effective at all times during the Registration Period, and, during such period,
comply with the provisions of the 1933 Act with respect to the disposition of
all Registrable Securities of the Company covered by such Registration Statement
until such time as all of such Registrable Securities shall have been disposed
of in accordance with the intended methods of disposition by the seller or
sellers thereof as set forth in such Registration Statement.  In the case of
amendments and supplements to a Registration Statement which are required to be
filed pursuant to this Agreement (including pursuant to this Section 3(b)) by
reason of the Company filing a report on Form 10-K, Form 10-Q or Form 8-K or any
analogous report under the Securities Exchange Act of 1934, as amended (the
"1934 Act"), the Company shall have incorporated such report by reference into
the Registration Statement, if applicable, or shall file such amendments or
supplements with the SEC on the same day on which the 1934 Act report is filed
which created the requirement for the Company to amend or supplement the
Registration Statement.

                                      -4-
<PAGE>

          c.   The Company shall furnish to each Investor whose Registrable
Securities are included in any Registration Statement, without charge, (i)
promptly after the same is prepared and filed with the SEC, at least one copy of
such Registration Statement and any amendment(s) thereto, including financial
statements and schedules, and all exhibits and each preliminary prospectus, (ii)
upon the effectiveness of any Registration Statement, ten (10) copies of the
prospectus included in such Registration Statement and all amendments and
supplements thereto (or such other number of copies as such Investor may
reasonably request) and (iii) such other documents, including copies of any
preliminary or final prospectus, as such Investor may reasonably request from
time to time in order to facilitate the disposition of the Registrable
Securities owned by such Investor.

          d.   The Company shall use its best efforts to (i) register and
qualify the Registrable Securities covered by a Registration Statement under all
other securities or "blue sky" laws of such jurisdictions in the United States,
(ii) prepare and file in those jurisdictions, such amendments (including post-
effective amendments) and supplements to such registrations and qualifications
as may be necessary to maintain the effectiveness thereof during the
Registration Period, (iii) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during the
Registration Period, and (iv) take all other actions reasonably necessary or
advisable to qualify the Registrable Securities for sale in such jurisdictions;
provided, however, that the Company shall not be required in connection
therewith or as a condition thereto to (w) make any change in the Company's
Certificate of Incorporation or by-laws that the Company's board of directors
determines in good faith to be contrary to the best interests of the Company and
its shareholders,  (x) qualify to do business in any jurisdiction where it would
not otherwise be required to qualify but for this Section 3(e), (y) subject
itself to general taxation in any such jurisdiction, or (z) file a general
consent to service of process in any such jurisdiction.  The Company shall
promptly notify  each Investor who holds Registrable Securities of the receipt
by the Company of any notification with respect to the suspension of the
registration or qualification of any of the Registrable Securities for sale
under the securities or "blue sky" laws of any jurisdiction in the United States
or its receipt of actual notice of the initiation or threat of any proceeding
for such purpose.

          e.   As promptly as practicable after becoming aware of such event or
development, the Company shall notify  each Investor in writing of the happening
of any event as a result of which the prospectus included in a Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omission to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, and promptly prepare a supplement or amendment to such
Registration Statement to correct such untrue statement or omission, and deliver
ten (10) copies of such supplement or amendment to  each Investor (or such other
number of copies as such Investor may reasonably request).  The Company shall
also promptly notify  each Investor in writing (i) when a prospectus or any
prospectus supplement or post-effective amendment has been filed, and when a
Registration Statement or any post-effective amendment has become effective
(notification of such effectiveness shall be delivered to  each Investor by
facsimile on the same day of such effectiveness), (ii) of any request by the SEC
for amendments or supplements to a Registration Statement or related

                                      -5-
<PAGE>

prospectus or related information, and (iii) of the Company's reasonable
determination that a post-effective amendment to a Registration Statement would
be appropriate.

          f.   The Company shall use its best efforts to prevent the issuance of
any stop order or other suspension of effectiveness of a Registration Statement,
or the suspension of the qualification of any of the Registrable Securities for
sale in any jurisdiction and, if such an order or suspension is issued, to
obtain the withdrawal of such order or suspension at the earliest possible
moment and to notify  each Investor who holds Registrable Securities being sold
of the issuance of such order and the resolution thereof or its receipt of
actual notice of the initiation or threat of any proceeding for such purpose.

          g.   The Company shall make available for inspection by any Investor
all pertinent financial and other records, and pertinent corporate documents and
properties of the Company (collectively, the "Records"), as shall be reasonably
deemed necessary by each Investor, and cause the Company's officers, directors
and employees to supply all information which any Investor may reasonably
request; provided, however, that each Investor hereby agrees to hold in strict
confidence and shall not make any disclosure (except to an Investor) or use of
any Record or other information which the Company determines in good faith to be
confidential, and of which determination the Investors are so notified, unless
(a) the disclosure of such Records is necessary to avoid or correct a
misstatement or omission in any Registration Statement or is otherwise required
under the 1933 Act, (b) the release of such Records is ordered pursuant to a
final, non-appealable subpoena or order from a court or government body of
competent jurisdiction, or (c) the information in such Records has been made
generally available to the public other than by disclosure in violation of this
or any other agreement of which the Investor has knowledge. Each Investor agrees
that it shall, upon learning that disclosure of such Records is sought in or by
a court or governmental body of competent jurisdiction or through other means,
give prompt notice to the Company and allow the Company, at its expense, to
undertake appropriate action to prevent disclosure of, or to obtain a protective
order for, the Records deemed confidential.

          h.   The Company shall hold in confidence and not make any disclosure
of information concerning an Investor provided to the Company unless (i)
disclosure of such information is necessary to comply with federal or state
securities laws, (ii) the disclosure of such information is necessary to avoid
or correct a misstatement or omission in any Registration Statement, (iii) the
release of such information is ordered pursuant to a subpoena or other final,
non-appealable order from a court or governmental body of competent
jurisdiction, or (iv) such information has been made generally available to the
public other than by disclosure in violation of this Agreement or any other
agreement, or (v) such Investor consents to the form and content of any such
disclosure.  The Company agrees that it shall, upon learning that disclosure of
such information concerning an Investor is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
written notice to such Investor and allow such Investor, at the Investor's
expense, to undertake appropriate action to prevent disclosure of, or to obtain
a protective order for, such information.

                                      -6-
<PAGE>

          i.   The Company shall use its best efforts either to (i) cause all
the Registrable Securities covered by a Registration Statement to be listed on
each securities exchange on which securities of the same class or series issued
by the Company are then listed, if any, if the listing of such Registrable
Securities is then permitted under the rules of such exchange, or (ii) secure
designation and quotation of all the Registrable Securities covered by the
Registration Statement on The Nasdaq SmallCap Market, the Nasdaq National Market
The American Stock Exchange, Inc., or The New York Stock Exchange, Inc.  The
Company shall pay all fees and expenses in connection with satisfying its
obligation under this Section 3(i).

          j.   The Company shall cooperate with the Investors who hold
Registrable Securities being offered and, to the extent applicable, to
facilitate the timely preparation and delivery of certificates (not bearing any
restrictive legend) representing the Registrable Securities to be offered
pursuant to a Registration Statement and enable such certificates to be in such
denominations or amounts, as the case may be, as the Investors may reasonably
request and registered in such names as the Investors may request.

          k.   The Company shall provide a transfer agent and registrar of all
such Registrable Securities not later than the effective date of such
Registration Statement.

          l.   If requested by an Investor, the Company shall (i) as soon as
practicable incorporate in a prospectus supplement or post-effective amendment
such information as an Investor requests to be included therein relating to the
sale and distribution of Registrable Securities, including, without limitation,
information with respect to the number of Registrable Securities being offered
or sold, the purchase price being paid therefor and any other terms of the
offering of the Registrable Securities to be sold in such offering; and (ii) as
soon as practicable make all required filings of such prospectus supplement or
post-effective amendment after being notified of the matters to be incorporated
in such prospectus supplement or post-effective amendment.

          m.   The Company shall use its best efforts to cause the Registrable
Securities covered by the applicable Registration Statement to be registered
with or approved by such other governmental agencies or authorities as may be
necessary to consummate the disposition of such Registrable Securities within
the United States.

          n.   The Company shall otherwise use its best efforts to comply with
all applicable rules and regulations of the SEC in connection with any
registration hereunder.

          o.   Within two (2) business days after a Registration Statement which
covers applicable Registrable Securities is ordered effective by the SEC, the
Company shall deliver, and shall cause legal counsel for the Company to deliver,
to the transfer agent for such Registrable Securities (with copies to the
Investors whose Registrable Securities are included in such Registration
Statement) confirmation that such Registration Statement has been declared
effective by the SEC.

                                      -7-
<PAGE>

          p.   The Company shall take all other reasonable actions necessary to
expedite and facilitate disposition by the Investors of Registrable Securities
pursuant to a Registration Statement.

          q.   Notwithstanding anything to the contrary in Section 3(f), at any
time after the applicable Registration Statement has been declared effective by
the SEC, the Company may delay the disclosure of material non-public information
concerning the Company the disclosure of which at the time is not, in the good
faith opinion of the Board of Directors of the Company and its counsel, in the
best interest of the Company and, in the opinion of counsel to the Company,
otherwise required (a "Grace Period"); provided, that the Company shall promptly
(i) notify the Investors in writing of the existence of material non-public
information giving rise to a Grace Period (provided that in each notice the
Company will not disclose the content of such material non-public information to
the Investors) and the date on which the Grace Period will begin, and (ii)
notify the Investors in writing of the date on which the Grace Period ends; and,
provided further, that no Grace Periods shall exceed 30 consecutive days and
during any consecutive 365 day period, such Grace Periods shall not exceed an
aggregate of 45 days (an "Allowable Grace Period").  For purposes of determining
the length of a Grace Period above, the Grace Period shall begin on and include
the date the holders receive the notice referred to in clause (i) and shall end
on and include the later of the date the holders receive the notice referred to
in clause (ii) and the date referred to in such notice. The provisions of
Sections 2(f) and 3(g) hereof shall not be applicable during the period of any
Allowable Grace Period.  Upon expiration of the Grace Period, the Company shall
again be bound by the first sentence of Section 3(f) with respect to the
information giving rise thereto unless such material non-public information is
no longer applicable.

     4.   OBLIGATIONS OF THE INVESTORS.
          ----------------------------

          a.   At least seven (7) days prior to the first anticipated filing
date of a Registration Statement, the Company shall notify each Investor in
writing of the information the Company requires from each such Investor if such
Investor elects to have any of such Investor's Registrable Securities included
in such Registration Statement.  It shall be a condition precedent to the
obligations of the Company to complete the registration pursuant to this
Agreement with respect to the Registrable Securities of a particular Investor
that such Investor shall furnish to the Company such information regarding
itself, the Registrable Securities held by it and the intended method of
disposition of the Registrable Securities held by it as shall be reasonably
required to effect the registration of such Registrable Securities and shall
execute such documents in connection with such registration as the Company may
reasonably request.

          b.   Each Investor by such Investor's acceptance of the Registrable
Securities agrees to cooperate with the Company as reasonably requested by the
Company in connection with the preparation and filing of any Registration
Statement hereunder, unless such Investor has notified the Company in writing of
such Investor's election to exclude all of such Investor's Registrable
Securities from such Registration Statement.

                                      -8-
<PAGE>

          c.   Each Investor agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 3(g) or
the first sentence of 3(f), such Investor will immediately discontinue
disposition of Registrable Securities pursuant to any Registration Statement(s)
covering such Registrable Securities until such Investor's receipt of the copies
of the supplemented or amended prospectus contemplated by Section 3(g) or the
first sentence of 3(f) or receipt of notice that no supplement or amendment is
required.  Notwithstanding anything to the contrary, the Company shall cause its
transfer agent to deliver unlegended shares of Common Stock to a transferee of
an Investor in accordance with the terms of the Securities Purchase Agreement in
connection with any sale of Registrable Securities with respect to which an
Investor has entered into a contract for sale prior to the Investor's receipt of
a notice from the Company of the happening of any event of the kind described in
Section 3(g) or the first sentence of 3(h) and for which the Investor has not
yet settled.

     5.   EXPENSES OF REGISTRATION.
          ------------------------

          All reasonable expenses, other than underwriting discounts and
commissions, incurred in connection with registrations, filings or
qualifications pursuant to Sections 2 and 3, including, without limitation, all
registration, listing and qualifications fees, printers and accounting fees
shall be paid by the Company.

     6.   INDEMNIFICATION.
          ---------------

          In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

          a.   To the fullest extent permitted by law, the Company will, and
hereby does, indemnify, hold harmless and defend each Investor, the directors,
officers, partners, employees, agents, representatives of, and each Person, if
any, who controls any Investor within the meaning of the 1933 Act or the
Securities Exchange Act of 1934, as amended (the "1934 Act") (each, an
"Indemnified Person"), against any losses, claims, damages, liabilities,
judgments, fines, penalties, charges, costs, reasonable attorneys' fees, amounts
paid in settlement or expenses, joint or several, (collectively, "Claims")
incurred in investigating, preparing or defending any action, claim, suit,
inquiry, proceeding, investigation or appeal taken from the foregoing by or
before any court or governmental, administrative or other regulatory agency,
body or the SEC, whether pending or threatened, whether or not an indemnified
party is or may be a party thereto ("Indemnified Damages"), to which any of them
may become subject insofar as such Claims (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based upon: (i)
any untrue statement or alleged untrue statement of a material fact in a
Registration Statement or any post-effective amendment thereto or in any filing
made in connection with the qualification of the offering under the securities
or other "blue sky" laws of any jurisdiction in which Registrable Securities are
offered ("Blue Sky Filing"), or the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, (ii) any untrue statement or alleged untrue statement of
a material fact contained in any preliminary

                                      -9-
<PAGE>

prospectus if used prior to the effective date of such Registration Statement,
or contained in the final prospectus (as amended or supplemented, if the Company
files any amendment thereof or supplement thereto with the SEC) or the omission
or alleged omission to state therein any material fact necessary to make the
statements made therein, in light of the circumstances under which the
statements therein were made, not misleading or (iii) any violation or alleged
violation by the Company of the 1933 Act, the 1934 Act, any other law,
including, without limitation, any state securities law, or any rule or
regulation thereunder relating to the offer or sale of the Registrable
Securities pursuant to a Registration Statement (the matters in the foregoing
clauses (i) through (iii) being, collectively, "Violations"). Subject to Section
6(c), the Company shall reimburse the Investors and each such controlling
person, promptly as such expenses are incurred and are due and payable, for any
legal fees or disbursements or other reasonable expenses incurred by them in
connection with investigating or defending any such Claim. Notwithstanding
anything to the contrary contained herein, the indemnification agreement
contained in this Section 6(a): (i) shall not apply to a Claim by an Indemnified
Person arising out of or based upon a Violation which occurs in reliance upon
and in conformity with information furnished in writing to the Company by such
Indemnified Person expressly for use in connection with the preparation of the
Registration Statement or any such amendment thereof or supplement thereto, if
such prospectus was timely made available by the Company pursuant to Section
3(d); (ii) shall not be available to the extent such Claim is based on a failure
of the Investor to deliver or to cause to be delivered the prospectus made
available by the Company, if such prospectus was timely made available by the
Company pursuant to Section 3(d); and (iii) shall not apply to amounts paid in
settlement of any Claim, if such settlement is effected without the prior
written consent of the Company, which consent shall not be unreasonably
withheld. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Person and shall survive
the transfer of the Registrable Securities by the Investors pursuant to Section
9.

          b.   In connection with any Registration Statement in which an
Investor is participating, each such Investor agrees to severally and not
jointly indemnify, hold harmless and defend, to the same extent and in the same
manner as is set forth in Section 6(a), the Company, each of its directors, each
of its officers who signs the Registration Statement, each of the Company's
agents or representatives and each Person, if any, who controls the Company
within the meaning of the 1933 Act or the 1934 Act (each an "Indemnified
Party"), against any Claim or Indemnified Damages to which any of them may
become subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such
Claim or Indemnified Damages arise out of or are 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 to the
Company by such Investor expressly for use in connection with such Registration
Statement; and, subject to Section 6(d), such Investor will reimburse any legal
or other expenses reasonably incurred by them in connection with investigating
or defending any such Claim; provided, however, that the indemnity agreement
contained in this Section 6(b) and the agreement with respect to contribution
contained in Section 7 shall not apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of such
Investor, which consent shall not be unreasonably withheld; provided, further,
however, that the Investor shall be liable under this Section 6(b) for only that
amount of a Claim or

                                      -10-
<PAGE>

Indemnified Damages as does not exceed the net proceeds to such Investor as a
result of the sale of Registrable Securities pursuant to such Registration
Statement. Such indemnity shall remain in full force and effect regardless of
any investigation made by or on behalf of such Indemnified Party and shall
survive the transfer of the Registrable Securities by the Investors pursuant to
Section 9. Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(b) with respect to any
prospectus shall not inure to the benefit of any Indemnified Party if the untrue
statement or omission of material fact contained in the prospectus was corrected
on a timely basis in the prospectus, as then amended or supplemented.

          c.   Promptly after receipt by an Indemnified Person or Indemnified
Party under this Section 6 of notice of the commencement of any action or
proceeding (including any governmental action or proceeding) involving a Claim,
such Indemnified Person or Indemnified Party shall, if a Claim in respect
thereof is to be made against any indemnifying party under this Section 6,
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 control of the defense thereof with counsel
mutually satisfactory to the indemnifying party and the Indemnified Person or
the Indemnified Party, as the case may be; provided, however, that an
Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses of not more than one counsel for such
Indemnified Person or Indemnified Party to be paid by the Indemnified Party or
Indemnified Person, if, in the reasonable opinion of counsel retained by the
indemnifying party, the representation by such counsel of the Indemnified Person
or Indemnified Party and the indemnifying party would be inappropriate due to
actual or potential differing  interests between such Indemnified Person or
Indemnified Party and any other party represented by such counsel in such
proceeding.  In the case of an Indemnified Person, legal counsel referred to in
the immediately preceding sentence shall be selected by the Investors holding a
majority in interest of the Registrable Securities included in the Registration
Statement to which the Claim relates.  The Indemnified Party or Indemnified
Person shall cooperate fully with the indemnifying party in connection with any
negotiation or defense of any such action or claim by the indemnifying party and
shall furnish to the indemnifying party all information reasonably available to
the Indemnified Party or Indemnified Person which relates to such action or
claim.  The indemnifying party shall keep the Indemnified Party or Indemnified
Person apprized as to the status of the defense or any settlement negotiations
with respect thereto.  No indemnifying party shall be liable for any settlement
of any action, claim or proceeding effected without its prior written consent.
No indemnifying party shall, without the prior written consent of the
Indemnified Party or Indemnified Person, consent to entry of any judgment or
enter into any settlement or other compromise which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party or Indemnified Person of a release from all liability in
respect to such claim or litigation.  Following indemnification as provided for
hereunder, the indemnifying party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms
or corporations relating to the matter for which indemnification has been made.
The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not relieve such
indemnifying party of any liability to the

                                      -11-
<PAGE>

Indemnified Person or Indemnified Party under this Section 6, except to the
extent that the indemnifying party is prejudiced in its ability to defend such
action.

          d.   The indemnification required by this Section 6 shall be made by
periodic payments of the amount thereof during the course of the investigation
or defense, as and when bills are received or Indemnified Damages are incurred.

          e.   The indemnity agreements contained herein shall be in addition to
(i) any cause of action or similar right of the Indemnified Party or Indemnified
Person against the indemnifying party or others, and (ii) any liabilities the
indemnifying party may be subject to pursuant to the law.

     7.   CONTRIBUTION.
          ------------

          To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no seller of Registrable Securities guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any seller of Registrable Securities who was not guilty of
fraudulent misrepresentation; and (ii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds received by
such seller from the sale of such Registrable Securities pursuant to such
Registration Statement.

     8.   REPORTS UNDER THE 1934 ACT.

          With a view to making available to the Investors the benefits of Rule
144 promulgated under the 1933 Act or any other similar rule or regulation of
the SEC that may at any time permit the Investors to sell securities of the
Company to the public without registration ("Rule 144"), the Company agrees to:

          a.   make and keep public information available, as those terms are
understood and defined in Rule 144;

          b.   file with the SEC in a timely manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company remains subject to such requirements (it being understood that
nothing herein shall limit the Company's obligations under Section 4(c) of the
Securities Purchase Agreement) and the filing of such reports and other
documents is required for the applicable provisions of Rule 144; and

          c.   furnish to each Investor so long as such Investor owns
Registrable Securities, promptly upon request, a written statement by the
Company that it has complied with the reporting requirements of Rule 144, the
1933 Act and the 1934 Act, and (ii) such other information as may be

                                      -12-
<PAGE>

reasonably requested to permit the investors to sell such securities pursuant to
Rule 144 without registration.

     9.   ASSIGNMENT OF REGISTRATION RIGHTS.
          ---------------------------------

          The rights under this Agreement shall be automatically assignable by
the Investors to any transferee of all or any portion of Registrable Securities
if: (i) the Investor agrees in writing with the transferee or assignee to assign
such rights, and a copy of such agreement is furnished to the Company within a
reasonable time after such assignment; (ii) the Company is, within a reasonable
time after such transfer or assignment, furnished with written notice of (a) the
name and address of such transferee or assignee, and (b) the securities with
respect to which such registration rights are being transferred or assigned;
(iii) immediately following such transfer or assignment the further disposition
of such securities by the transferee or assignee is restricted under the 1933
Act and applicable state securities laws; (iv) at or before the time the Company
receives the written notice contemplated by clause (ii) of this sentence the
transferee or assignee agrees in writing with the Company to be bound by all of
the provisions contained herein; and (v) such transfer shall have been made in
accordance with the applicable requirements of the Securities Purchase
Agreement.

     10.  AMENDMENT OF REGISTRATION RIGHTS.
          --------------------------------

          Provisions 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 Investors who then hold at least two-thirds (2/3) of the principal amount of
the Notes which are then outstanding.  Any amendment or waiver effected in
accordance with this Section 10 shall be binding upon each Investor and the
Company.  No such amendment shall be effective to the extent that it applies to
less than all of the holders of the Registrable Securities.  No consideration
shall be offered or paid to any Person to amend or consent to a waiver or
modification of any provision of any of this Agreement unless the same
consideration also is offered to all of the parties to this Agreement.

     11.  MISCELLANEOUS.
          -------------

          a.   A Person is deemed to be a holder of Registrable Securities
whenever such Person owns or is deemed to own of record such Registrable
Securities.  If the Company receives conflicting instructions, notices or
elections from two or more Persons with respect to the same Registrable
Securities, the Company shall act upon the basis of instructions, notice or
election received from the registered owner of such Registrable Securities.

          b.   Any notices, consents, waivers or other communications required
or permitted to be given under the terms of this Agreement must be in writing

validity or enforceability of any provision of this Agreement in any other
jurisdiction. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND
AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE

         a.  Mandatory Registration.
             ----------------------

             (i)    Initial Mandatory Registration. The Company shall prepare,
                    ------------------------------
and, as soon as practicable, but in no event later than 60 days after the
Closing Date (as defined in the Securities Purchase Agreement) (the "Initial
Filing Deadline") file with the SEC an Initial Registration Statement or Initial
Registration Statements (as necessary) on Form S-3 covering the resale of all of
the Initial Registrable Securities relating to the Initial Notes and Initial
Warrants which are to be issued on the Initial Closing Date (as defined in the
Securities Purchase Agreement). In the event that Form S-3 is unavailable for
such a registration, the Company shall use such other form as is available for
such a registration, subject to the provisions of Section 2(e). Any first
Registration Statement prepared pursuant hereto shall register for resale at
least that number of shares of Common Stock equal to the sum of (y) the product
of (i) 2.0 and (ii) the number of Initial Conversion Shares issuable upon
conversion of the Initial Notes (without regard to any limitations on
conversions) as of the date immediately preceding the date the Initial
Registration Statement is initially filed with the SEC, subject to adjustment as
provided in Section 3(b), plus (z) the number of Initial Warrant Shares issuable
upon exercise of the Initial Warrant (without regard to any limitations on
exercise) as of the date immediately preceding the date the Initial Registration
Statement is initially filed with the SEC, subject to adjustment as provided in
Section 3(b). The Company shall use its best efforts to cause such Registration
Statement to be declared effective by the SEC as soon as possible, but in no
event later than 135 days after the Initial Closing Date (the "Initial
Effectiveness Deadline").

             (ii)   Additional Mandatory Registration. The Company shall
                    ---------------------------------
prepare, and, as soon as practicable, but in no event later than 20 days after
the Additional Note Notice Date (as defined in the Securities Purchase
Agreement) (the "Additional Filing Deadline") file with the SEC an Additional
Registration Statement or Additional Registration Statements (as

                                       3
<PAGE>

necessary) on Form S-3 covering the resale of all of the Additional Registrable
Securities relating to the Additional Notes and Additional Warrants which are to
be issued on the Additional Closing Date (as defined in the Securities Purchase
Agreement). In the event that Form S-3 is unavailable for such a registration,
the Company shall use such other form as is available for such a registration,
subject to the provisions of Section 2(e). Any first Registration Statement
prepared pursuant hereto shall register for resale at least that number of
shares of Common Stock equal to the sum of (y) the product of (i) 2.0 and (ii)
the number of Additional Conversion Shares issuable upon conversion of the
Additional Notes to be issued on the Additional Closing Date (as if such
Additional Notes were then outstanding and without regard to any limitations on
conversions) as of the date immediately preceding the date the Additional
Registration Statement is initially filed with the SEC, subject to adjustment as
provided in Section 3(b), plus (z) the number of Additional Warrant Shares
issuable upon exercise of the Additional Warrants to be issued on the Additional
Closing Date (as if such Additional Warrants were then outstanding and without
regard to any limitations on exercise) as of the date immediately preceding the
date the Additional Registration Statement is initially filed with the SEC,
subject to adjustment as provided in Section 3(b). The Company shall use its
best efforts to cause such Registration Statement to be declared effective by
the SEC as soon as possible, but in no event later than 80 days after the
Additional Closing Date (the "Additional Effectiveness Deadline").

          b.  Piggy-Back Registrations.  If at any time prior to the expiration
              ------------------------
of the Registration Period (as hereinafter defined), the number of shares of
Common Stock available for sale under a Registration Statement is insufficient
(as that term is used in Section 2(f)) to cover all of the Registrable
Securities and the Company proposes to file with the SEC a Registration
Statement relating to an offering for its own account or the account of others
under the 1933 Act of any of its securities (other than on Form S-4, Form S-8 or
Form S-1 (or their equivalents at such time) relating to securities to be issued
solely in connection with any acquisition of any entity or business; equity
securities issuable in connection with stock option or other employee benefit
plans; or equity securities issuable to non-affiliates of the Company in
connection with the Company's "distributor option plan" approved by the board of
directors of the Company) the Company shall promptly send to each Investor who
is entitled to registration rights under this Section 2(b) written notice of the
Company's intention to file a Registration Statement and of such Investor's
rights under this Section 2(b) and, if within twenty (20) days after receipt of
such notice, such Investor shall so request in writing, the Company shall
include in such Registration Statement all or any part of the Registrable
Securities such Investor requests to be registered, subject to the priorities
set forth in Section 2(b) below.  No right to registration of Registrable
Securities under this Section 2(b) shall be construed to limit any registration
required under Section 2(a).  The obligations of the Company under this Section
2(b) may be waived by Investors holding a majority of the Registrable
Securities.  If an offering in connection with which an Investor is entitled to
registration under this Section 2(b) is an underwritten offering, then each
Investor whose Registrable Securities are included in such Registration
Statement shall, unless otherwise agreed by the Company, offer and sell such
Registrable Securities in an underwritten

                                       4
<PAGE>

offering using the same underwriter or underwriters and, subject to the
provisions of this Agreement, on the same terms and conditions as other shares
of Common Stock included in such underwritten offering. If a registration
pursuant to this Section 2(b) is to be an underwritten public offering and the
managing underwriter(s) advise the Company in writing, that in their reasonable
good faith opinion, marketing or other factors dictate that a limitation on the
number of shares of Common Stock which may be included in the Registration
Statement is necessary to facilitate and not adversely affect the proposed
offering, then the Company shall include in such registration: (1) first, all
securities the Company proposes to sell for its own account, (2) second, up to
the full number of securities proposed to be registered for the account of the
holders of securities entitled to inclusion of their securities in the
Registration Statement by reason of demand registration rights, and (3) third,
the securities requested to be registered by the holders of the securities
entitled to participate in the registration under the Amended and Restated
Registration Rights Agreement dated March 7, 1998, (4) fourth, the securities
requested to be registered by the Investors and other holders of securities
entitled to participate in the registration, as of the date hereof, drawn from
them pro rata based on the number each has requested to be included in such
registration, including those holders of registration rights pursuant to the
Registration Rights Agreement dated September 7, 1999.

          c.  Allocation of Registrable Securities.  The initial number of
              ------------------------------------
Registrable Securities included in any Registration Statement and each increase
in the number of Registrable Securities included therein shall be allocated pro
rata among the Investors based on the number of Registrable Securities held by
each Investor at the time the Registration Statement covering such initial
number of Registrable Securities or increase thereof is declared effective by
the SEC.  In the event that an Investor sells or otherwise transfers any of such
Person's Registrable Securities, each transferee shall be allocated a pro rata
portion of the then remaining number of Registrable Securities included in such
Registration Statement for such transferor.  Any shares of Common Stock included
in a Registration Statement and which remain allocated to any Person which
ceases to hold any Registrable Securities covered by such Registration Statement
shall be allocated to the remaining Investors, pro rata based on the number of
Registrable Securities then held by such Investors which are covered by such
Registration Statement.

          d.  Legal Counsel.  Subject to Section 5 hereof, the Buyers holding a
              -------------
majority of the Registrable Securities shall have the right to select one legal
counsel to review and oversee any offering pursuant to this Section 2 ("Legal
Counsel"), which shall be Katten Muchin & Zavis or such other counsel as
thereafter designated by the holders of a majority of Registrable Securities and
of which the Company and its counsel have been given prior notice.  The Company
shall reasonably cooperate with Legal Counsel in performing the Company's
obligations under this Agreement.

          e.  Ineligibility for Form S-3.  In the event that Form S-3 is not
              --------------------------
available for any registration of Registrable Securities hereunder, the Company
shall (i) register the sale of the

                                       5
<PAGE>

Registrable Securities on another appropriate form reasonably acceptable to the
holders of a majority of the Registrable Securities and (ii) undertake to
register the Registrable Securities on Form S-3 as soon as such form is
available, provided that the Company shall maintain the effectiveness of the
Registration Statement then in effect until such time as a Registration
Statement on Form S-3 covering the Registrable Securities has been declared
effective by the SEC.

          f.  Sufficient Number of Shares Registered. In the event the number of
              --------------------------------------
shares available under a Registration Statement filed pursuant to Section 2(a)
is insufficient to cover all of the Registrable Securities which such
Registration Statement is required to cover or an

                                       6
<PAGE>

Investor's allocated portion of the Registrable Securities pursuant to Section
2(c), the Company shall amend the Registration Statement, or file a new
Registration Statement (on the short form available therefor, if applicable), or
both, so as to cover at least 150% of the Registrable Securities (based on the
market price of the Common Stock on the trading day immediately preceding the
date of filing of such amendment or new Registration Statement), in each case,
as soon as practicable, but in any event not later than fifteen (15) days after
the necessity therefor arises. The Company shall use its best efforts to cause
such amendment and/or new Registration Statement to become effective as soon as
practicable following the filing thereof. For purposes of the foregoing
provision, the number of shares available under a Registration Statement shall
be deemed "insufficient to cover all of the Registrable Securities" if the
number of Registrable Securities issued or issuable upon conversion of the Notes
and exercise of the Warrants covered by such Registration Statement for five
consecutive trading days is greater than the quotient determined by dividing (i)
the number of shares of Common Stock available for resale under such
Registration Statement and (ii) 1.5. For purposes of the calculation set forth
in the foregoing sentence, any restrictions on the convertibility of the Notes
or exercise of the Warrants shall be disregarded and such calculation shall
assume that the Notes are then convertible into, and the Warrants are then
exercisable for, shares of Common Stock at the then prevailing Conversion Rate
(as defined in the Notes) or Warrant Exercise Price (as defined in the
Warrants), respectively.

     3.  RELATED OBLIGATIONS.
         -------------------

     At such time as the Company is obligated to file a Registration Statement
with the SEC pursuant to Section 2(a) or 2(f), the Company will use its best
efforts to effect the registration of the Registrable Securities in accordance
with the intended method of disposition thereof and, pursuant thereto, the
Company shall have the following obligations:

         a.  The Company shall promptly prepare and file with the SEC a
Registration Statement with respect to the Registrable Securities (but in no
event later than the Filing Deadline) and use its best efforts to cause such
Registration Statement relating to the Registrable Securities to become
effective as soon as practicable after such filing (but in no event later than
the applicable Effectiveness Deadline).  The Company shall keep each
Registration Statement effective pursuant to Rule 415 at all times until the
earlier of (i) the date as of which the Investors may sell all of the
Registrable Securities covered by such Registration Statement without
restriction pursuant to Rule 144(k) promulgated under the 1933 Act (or successor
thereto) or (ii) the date on which the Investors shall have sold all the
Registrable Securities covered by such Registration Statement (the "Registration
Period"), which Registration Statement (including any amendments or supplements
thereto and prospectuses contained therein) shall not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein, or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading.  The term "best efforts"
as used in the first sentence of this Section 3(a) shall mean, among other
things, that the Company shall submit to the SEC, within two (2) business days
after

                                       7
<PAGE>

the Company learns that no review of a particular Registration Statement will be
made by the staff of the SEC or that the staff has no further comments on the
Registration Statement, as the case may be, a request for acceleration of
effectiveness of such Registration Statement to a time and date not later than
two (2) business days after the submission of such request.

          b.  The Company shall prepare and file with the SEC such amendments
(including post-effective amendments) and supplements to a Registration
Statement and the prospectus used in connection with such Registration
Statement, which prospectus is to be filed pursuant to Rule 424 promulgated
under the 1933 Act, as may be necessary to keep such Registration Statement
effective at all times during the Registration Period, and, during such period,
comply with the provisions of the 1933 Act with respect to the disposition of
all Registrable Securities of the Company covered by such Registration Statement
until such time as all of such Registrable Securities shall have been disposed
of in accordance with the intended methods of disposition by the seller or
sellers thereof as set forth in such Registration Statement.  In the case of
amendments and supplements to a Registration Statement which are required to be
filed pursuant to this Agreement (including pursuant to this Section 3(b)) by
reason of the Company filing a report on Form 10-K, Form 10-Q or Form 8-K or any
analogous report under the Securities Exchange Act of 1934, as amended (the
"1934 Act"), the Company shall have incorporated such report by reference into
the Registration Statement, if applicable, or shall file such amendments or
supplements with the SEC on the same day on which the 1934 Act report is filed
which created the requirement for the Company to amend or supplement the
Registration Statement.

          c.  The Company shall (a) permit Legal Counsel to review and comment
upon those sections of (i) the Initial Registration Statement and the Additional
Registration Statement which are applicable to the Buyers at least five (5)
business days prior to its filing with the SEC and (ii) all other Registration
Statements and all amendments and supplements to all Registration Statements
which are applicable to the Buyers (except for Annual Reports on Form 10-K,
Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and any similar
or successor reports) within a reasonable number of days prior to the their
filing with the SEC and (b) not file any document in a form to which Legal
Counsel reasonably objects. The Company shall not submit a request for
acceleration of the effectiveness of a Registration Statement or any amendment
or supplement thereto without the prior approval of Legal Counsel, which consent
shall not be unreasonably withheld. The Company shall furnish to Legal Counsel,
without charge, (i) any correspondence from the SEC or the staff of the SEC to
the Company or its representatives relating to any Registration Statement,
provided the Investors and Legal Counsel keep such correspondence confidential,
(ii) promptly after the same is prepared and filed with the SEC, one copy of any
Registration Statement and any amendment(s) thereto, including financial
statements and schedules and all exhibits and (iii) upon the effectiveness of
any Registration Statement, one copy of the prospectus included in such
Registration Statement and all amendments and

                                       8
<PAGE>

supplements thereto. The Company shall reasonably cooperate with Legal Counsel
in performing the Company's obligations pursuant to this Section 3.

          d.  The Company shall furnish to each Investor whose Registrable
Securities are included in any Registration Statement, without charge, (i)
promptly after the same is prepared and filed with the SEC, at least one copy of
such Registration Statement and any amendment(s) thereto, including financial
statements and schedules, and all exhibits and each preliminary prospectus, (ii)
upon the effectiveness of any Registration Statement, ten (10) copies of the
prospectus included in such Registration Statement and all amendments and
supplements thereto (or such other number of copies as such Investor may
reasonably request) and (iii) such other documents, including copies of any
preliminary or final prospectus, as such Investor may reasonably request from
time to time in order to facilitate the disposition of the Registrable
Securities owned by such Investor.

          e.  The Company shall use its best efforts to (i) register and qualify
the Registrable Securities covered by a Registration Statement under all other
securities or "blue sky" laws of such jurisdictions in the United States, (ii)
prepare and file in those jurisdictions, such amendments (including post-
effective amendments) and supplements to such registrations and qualifications
as may be necessary to maintain the effectiveness thereof during the
Registration Period, (iii) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during the
Registration Period, and (iv) take all other actions reasonably necessary or
advisable to qualify the Registrable Securities for sale in such jurisdictions;
provided, however, that the Company shall not be required in connection
therewith or as a condition thereto to (w) make any change in the Company's
Certificate of Incorporation or by-laws that the Company's board of directors
determines in good faith to be contrary to the best interests of the Company and
its shareholders,  (x) qualify to do business in any jurisdiction where it would
not otherwise be required to qualify but for this Section 3(e), (y) subject
itself to general taxation in any such jurisdiction, or (z) file a general
consent to service of process in any such jurisdiction.  The Company shall
promptly notify Legal Counsel and each Investor who holds Registrable Securities
of the receipt by the Company of any notification with respect to the suspension
of the registration or qualification of any of the Registrable Securities for
sale under the securities or "blue sky" laws of any jurisdiction in the United
States or its receipt of actual notice of the initiation or threat of any
proceeding for such purpose.

          f.  As promptly as practicable after becoming aware of such event or
development, the Company shall notify Legal Counsel and each Investor in writing
of the happening of any event as a result of which the prospectus included in a
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omission to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, and promptly prepare a supplement or
amendment to such Registration Statement to correct such untrue statement or
omission, and

                                       9
<PAGE>

deliver ten (10) copies of such supplement or amendment to Legal Counsel and
each Investor (or such other number of copies as Legal Counsel or such Investor
may reasonably request). The Company shall also promptly notify Legal Counsel
and each Investor in writing (i) when a prospectus or any prospectus supplement
or post-effective amendment has been filed, and when a Registration Statement or
any post-effective amendment has become effective (notification of such
effectiveness shall be delivered to Legal Counsel and each Investor by facsimile
on the same day of such effectiveness), (ii) of any request by the SEC for
amendments or supplements to a Registration Statement or related prospectus or
related information, and (iii) of the Company's reasonable determination that a
post-effective amendment to a Registration Statement would be appropriate.

          g.  The Company shall use its best efforts to prevent the issuance of
any stop order or other suspension of effectiveness of a Registration Statement,
or the suspension of the qualification of any of the Registrable Securities for
sale in any jurisdiction and, if such an order or suspension is issued, to
obtain the withdrawal of such order or suspension at the earliest possible
moment and to notify Legal Counsel and each Investor who holds Registrable
Securities being sold of the issuance of such order and the resolution thereof
or its receipt of actual notice of the initiation or threat of any proceeding
for such purpose.

          h.  At the reasonable request of any Investor and at such Investor=s
expense, the Company shall furnish to such Investor, on the date of the
effectiveness of the Registration Statement and thereafter from time to time on
such dates as an Investor may reasonably request (i) a letter, dated such date,
from the  Company's independent certified public accountants in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, and (ii) an opinion, dated as
of such date, of counsel representing the Company for purposes of such
Registration Statement, in form, scope and substance as is customarily given in
an underwritten public offering, addressed to the Investors.

          i.  The Company shall make available for inspection by (i) any
Investor, (ii) Legal Counsel and (iii) one firm of accountants or other agents
retained by the Investors (collectively, the "Inspectors") all pertinent
financial and other records, and pertinent corporate documents and properties of
the Company (collectively, the "Records"), as shall be reasonably deemed
necessary by each Inspector, and cause the Company's officers, directors and
employees to supply all information which any Inspector may reasonably request;
provided, however, that each Inspector which is not a party hereto shall agree
in writing prior to obtaining access to any Records, and each Investor hereby
agrees, to hold in strict confidence and shall not make any disclosure (except
to an Investor) or use of any Record or other information which the Company
determines in good faith to be confidential, and of which determination the
Inspectors are so notified, unless (a) the disclosure of such Records is
necessary to avoid or correct a misstatement or omission in any Registration
Statement or is otherwise required under the 1933 Act, (b) the release of such
Records is ordered pursuant to a final, non-appealable subpoena or order from a

                                       10
<PAGE>

court or government body of competent jurisdiction, or (c) the information in
such Records has been made generally available to the public other than by
disclosure in violation of this or any other agreement of which the Inspector
has knowledge. The Company shall not be required to disclose any confidential
information in such Records to any Inspector until and unless such Inspector
shall have entered into confidentiality agreements with the Company with respect
thereto, substantially in the form of this Section 3(i). Each Investor agrees
that it shall, upon learning that disclosure of such Records is sought in or by
a court or governmental body of competent jurisdiction or through other means,
give prompt notice to the Company prior to making any such disclosure and allow
the Company, at its expense, to undertake appropriate action to prevent
disclosure of, or to obtain a protective order for, the Records deemed
confidential.

          j.  The Company shall hold in confidence and not make any disclosure
of information concerning an Investor provided to the Company unless (i)
disclosure of such information is necessary to comply with federal or state
securities laws, (ii) the disclosure of such information is necessary to avoid
or correct a misstatement or omission in any Registration Statement, (iii) the
release of such information is ordered pursuant to a subpoena or other final,
non-appealable order from a court or governmental body of competent
jurisdiction, or (iv) such information has been made generally available to the
public other than by disclosure in violation of this Agreement or any other
agreement, or (v) such Investor consents to the form and content of any such
disclosure.  The Company agrees that it shall, upon learning that disclosure of
such information concerning an Investor is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
written notice to such Investor prior to making any such disclosure and allow
such Investor, at the Investor's expense, to undertake appropriate action to
prevent disclosure of, or to obtain a protective order for, such information.

          k.  The Company shall use its best efforts either to (i) cause all the
Registrable Securities covered by a Registration Statement to be listed on each
securities exchange on which securities of the same class or series issued by
the Company are then listed, if any, if the listing of such Registrable
Securities is then permitted under the rules of such exchange, or (ii) secure
designation and quotation of all the Registrable Securities covered by the
Registration Statement on The Nasdaq SmallCap Market, the Nasdaq National Market
The American Stock Exchange, Inc., or The New York Stock Exchange, Inc.  The
Company shall pay all fees and expenses in connection with satisfying its
obligation under this Section 3(k).

          l.  The Company shall cooperate with the Investors who hold
Registrable Securities being offered and, to the extent applicable, to
facilitate the timely preparation and delivery of certificates (not bearing any
restrictive legend) representing the Registrable Securities to be offered
pursuant to a Registration Statement and enable such certificates to be in such
denominations or amounts, as the case may be, as the Investors may reasonably
request and registered in such names as the Investors may request.

                                       11
<PAGE>

          m.  The Company shall provide a transfer agent and registrar of all
such Registrable Securities not later than the effective date of such
Registration Statement.

          n.  If requested by an Investor, the Company shall (i) as soon as
practicable incorporate in a prospectus supplement or post-effective amendment
such information as an Investor requests to be included therein relating to the
Investor and the sale and distribution of Registrable Securities, including,
without limitation, information with respect to the number of Registrable
Securities being offered or sold, the purchase price being paid therefor and any
other terms of the offering of the Registrable Securities to be sold in such
offering; and (ii) as soon as practicable make all required filings of such
prospectus supplement or post-effective amendment after being notified of the
matters to be incorporated in such prospectus supplement or post-effective
amendment.

          o.  The Company shall use its best efforts to cause the Registrable
Securities covered by the applicable Registration Statement to be registered
with or approved by such other governmental agencies or authorities as may be
necessary to consummate the disposition of such Registrable Securities within
the United States.

          p.  The Company shall make generally available to its security holders
as soon as practicable, but not later than 90 days after the close of the period
covered thereby, an earnings statement (in form complying with the provisions of
Rule 158 under the 1933 Act) covering a twelve-month period beginning not later
than the first day of the Company's fiscal quarter next following the effective
date of the Registration Statement.

          q.  The Company shall otherwise use its best efforts to comply with
all applicable rules and regulations of the SEC in connection with any
registration hereunder.

          r.  Within two (2) business days after a Registration Statement which
covers applicable Registrable Securities is ordered effective by the SEC, the
Company shall deliver, and shall cause legal counsel for the Company to deliver,
to the transfer agent for such Registrable Securities (with copies to the
Investors whose Registrable Securities are included in such Registration
Statement) confirmation that such Registration Statement has been declared
effective by the SEC in the form attached hereto as Exhibit A.
                                                    ---------

          s.  Notwithstanding anything to the contrary in Section 3(f), at any
time after the applicable Registration Statement has been declared effective by
the SEC, the Company may delay the disclosure of material non-public information
concerning the Company the disclosure of which at the time is not, in the good
faith opinion of the Board of Directors of the Company and its counsel, in the
best interest of the Company and, in the opinion of counsel to the Company,
otherwise required (a "Grace Period"); provided, that the Company shall promptly
(i) notify the Investors in writing of the existence of material non-public
information giving rise to

                                       12
<PAGE>

a Grace Period (provided that in each notice the Company will not disclose the
content of such material non-public information to the Investors) and the date
on which the Grace Period will begin, and (ii) notify the Investors in writing
of the date on which the Grace Period ends; and, provided further, that no Grace
Periods shall exceed 15 consecutive days and during any consecutive 365 day
period, such Grace Periods shall not exceed an aggregate of 30 days (an
"Allowable Grace Period"). For purposes of determining the length of a Grace
Period above, the Grace Period shall begin on and include the date the holders
receive the notice referred to in clause (i) and shall end on and include the
later of the date the holders receive the notice referred to in clause (ii) and
the date referred to in such notice. The provisions of Section 3(g) hereof shall
not be applicable during the period of any Allowable Grace Period. Upon
expiration of the Grace Period, the Company shall again be bound by the first
sentence of Section 3(f) with respect to the information giving rise thereto
unless such material non-public information is no longer applicable.

     4.  OBLIGATIONS OF THE INVESTORS.
         ----------------------------

         a.  At least seven (7) days prior to the first anticipated filing date
of a Registration Statement, the Company shall notify each Investor in writing
of the information the Company requires from each such Investor if such Investor
elects to have any of such Investor's Registrable Securities included in such
Registration Statement. It shall be a condition precedent to the obligations of
the Company to complete the registration pursuant to this Agreement with respect
to the Registrable Securities of a particular Investor that such Investor shall
furnish to the Company such information regarding itself, the Registrable
Securities held by it and the intended method of disposition of the Registrable
Securities held by it as shall be reasonably required to effect the registration
of such Registrable Securities and shall execute such documents in connection
with such registration as the Company may reasonably request. If an Investor
does not provide the Company with the information it has requested pursuant to
this Section 4(a) within seven (7) days of being notified by the Company of its
necessity, then for every day after such seventh (7th) day until such date as
such Investor provided the requested information, the applicable Effectiveness
Deadline shall be extended by one (1) day for such Investor.

         b.  Each Investor by such Investor's acceptance of the Registrable
Securities agrees to cooperate with the Company as reasonably requested by the
Company in connection with the preparation and filing of any Registration
Statement hereunder, unless such Investor has notified the Company in writing of
such Investor's election to exclude all of such Investor's Registrable
Securities from such Registration Statement.

         c.  Each Investor agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 3(g) or
the first sentence of 3(f), such Investor will immediately discontinue
disposition of Registrable Securities pursuant to any Registration Statement(s)
covering such Registrable Securities until such Investor's receipt of the

                                       13
<PAGE>

copies of the supplemented or amended prospectus contemplated by Section 3(g) or
the first sentence of 3(f) or receipt of notice that no supplement or amendment
is required. Notwithstanding anything to the contrary, the Company shall cause
its transfer agent to deliver unlegended shares of Common Stock to a transferee
of an Investor in accordance with the terms of the Securities Purchase Agreement
in connection with any sale of Registrable Securities with respect to which an
Investor has entered into a contract for sale prior to the Investor's receipt of
a notice from the Company of the happening of any event of the kind described in
Section 3(g) or the first sentence of 3(h) and for which the Investor has not
yet settled.

         d.  As promptly as practicable after becoming aware of such event,
each Investor shall notify the Company in writing of the happening of any event
as a result of which the information provided in writing by such Investor to the
Company expressly for use in the Prospectus included in a Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omission to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

     5.  EXPENSES OF REGISTRATION.
         ------------------------

         All reasonable expenses, other than underwriting discounts and
commissions, incurred in connection with registrations, filings or
qualifications pursuant to Sections 2 and 3, including, without limitation, all
registration, listing and qualifications fees, printers and accounting fees
shall be paid by the Company.  In addition, the Company shall reimburse the
Investors for the reasonable fees and disbursements of Legal Counsel in
connection with registrations, filings or qualifications pursuant to Sections 2
and 3 of this Agreement, provided that the Company shall only reimburse that
amount, if any, equal to up to $10,000.

     6.  INDEMNIFICATION.
         ---------------

         In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

         a.  To the fullest extent permitted by law, the Company will, and
hereby does, indemnify, hold harmless and defend each Investor, the directors,
officers, partners, employees, agents, representatives of, and each Person, if
any, who controls any Investor within the meaning of the 1933 Act or the
Securities Exchange Act of 1934, as amended (the "1934 Act") (each, an
"Indemnified Person"), against any losses, claims, damages, liabilities,
judgments, fines, penalties, charges, costs, reasonable attorneys' fees, amounts
paid in settlement or expenses, joint or several, (collectively, "Claims")
incurred in investigating, preparing or defending any action, claim, suit,
inquiry, proceeding, investigation or appeal taken from the foregoing by or
before any court or governmental, administrative or other regulatory agency,
body or the SEC, whether

                                       14
<PAGE>

pending or threatened, whether or not an indemnified party is or may be a party
thereto ("Indemnified Damages"), to which any of them may become subject insofar
as such Claims (or actions or proceedings, whether commenced or threatened, in
respect thereof) arise out of or are based upon: (i) any untrue statement or
alleged untrue statement of a material fact in a Registration Statement or any
post-effective amendment thereto or in any filing made in connection with the
qualification of the offering under the securities or other "blue sky" laws of
any jurisdiction in which Registrable Securities are offered ("Blue Sky
Filing"), or the omission or alleged omission to state a material fact required
to be stated therein or necessary to make the statements therein not misleading,
(ii) any untrue statement or alleged untrue statement of a material fact
contained in any preliminary prospectus if used prior to the effective date of
such Registration Statement, or contained in the final prospectus (as amended or
supplemented, if the Company files any amendment thereof or supplement thereto
with the SEC) or the omission or alleged omission to state therein any material
fact necessary to make the statements made therein, in light of the
circumstances under which the statements therein were made, not misleading or
(iii) any violation or alleged violation by the Company of the 1933 Act, the
1934 Act, any other law, including, without limitation, any state securities
law, or any rule or regulation thereunder relating to the offer or sale of the
Registrable Securities pursuant to a Registration Statement (the matters in the
foregoing clauses (i) through (iii) being, collectively, "Violations"). Subject
to Section 6(c), the Company shall reimburse the Investors and each such
controlling person, promptly as such expenses are incurred and are due and
payable, for any legal fees or disbursements or other reasonable expenses
incurred by them in connection with investigating or defending any such Claim.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 6(a): (i) shall not apply to a Claim by an
Indemnified Person arising out of or based upon a Violation which occurs in
reliance upon and in conformity with information furnished in writing to the
Company by such Indemnified Person expressly for use in connection with the
preparation of the Registration Statement or any such amendment thereof or
supplement thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(d); (ii) shall not be available to the extent such Claim
is based on a failure of the Investor to deliver or to cause to be delivered the
prospectus made available by the Company, if such prospectus was timely made
available by the Company pursuant to Section 3(d); (iii) shall not apply to
amounts paid in settlement of any Claim, if such settlement is effected without
the prior written consent of the Company, which consent shall not be
unreasonably withheld and (iv) shall not apply to the cost of investigation of
any non-threatened potential claim. Such indemnity shall remain in full force
and effect regardless of any investigation made by or on behalf of the
Indemnified Person and shall survive the transfer of the Registrable Securities
by the Investors pursuant to Section 9.

         b.  In connection with any Registration Statement in which an Investor
is participating, each such Investor agrees to severally and not jointly
indemnify, hold harmless and defend, to the same extent and in the same manner
as is set forth in Section 6(a), the Company, each of its directors, each of its
officers who signs the Registration Statement, each of the Company's agents or
representatives, and each Person, if any, who controls the Company within

                                       15
<PAGE>

the meaning of the 1933 Act or the 1934 Act (each an "Indemnified Party"),
against any Claim or Indemnified Damages to which any of them may become
subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim or
Indemnified Damages arise out of or are 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 to the Company by such
Investor expressly for use in connection with such Registration Statement; and,
subject to Section 6(d), such Investor will reimburse any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such Claim; provided, however, that the indemnity agreement
contained in this Section 6(b) and the agreement with respect to contribution
contained in Section 7 shall not apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of such
Investor, which consent shall not be unreasonably withheld; provided, further,
however, that the Investor shall be liable under this Section 6(b) for only that
amount of a Claim or Indemnified Damages as does not exceed the net proceeds to
such Investor as a result of the sale of Registrable Securities pursuant to such
Registration Statement. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Indemnified Party
and shall survive the transfer of the Registrable Securities by the Investors
pursuant to Section 9. Notwithstanding anything to the contrary contained
herein, the indemnification agreement contained in this Section 6(b) with
respect to any prospectus shall not inure to the benefit of any Indemnified
Party if the untrue statement or omission of material fact contained in the
prospectus was corrected on a timely basis in the prospectus, as then amended or
supplemented.

         c.  Promptly after receipt by an Indemnified Person or Indemnified
Party under this Section 6 of notice of the commencement of any action or
proceeding (including any governmental action or proceeding) involving a Claim,
such Indemnified Person or Indemnified Party shall, if a Claim in respect
thereof is to be made against any indemnifying party under this Section 6,
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 control of the defense thereof with counsel
mutually satisfactory to the indemnifying party and the Indemnified Person or
the Indemnified Party, as the case may be; provided, however, that an
Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses of not more than one counsel for such
Indemnified Person or Indemnified Party to be paid by the indemnifying party,
if, in the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying party would be inappropriate due to actual or potential
differing  interests between such Indemnified Person or Indemnified Party and
any other party represented by such counsel in such proceeding.  In the case of
an Indemnified Person, legal counsel referred to in the immediately preceding
sentence shall be selected by the Investors holding a majority in interest of
the Registrable Securities included in the Registration Statement to which the
Claim relates.  The Indemnified Party or Indemnified Person shall cooperate
fully with the indemnifying

                                       16
<PAGE>

party in connection with any negotiation or defense of any such action or claim
by the indemnifying party and shall furnish to the indemnifying party all
information reasonably available to the Indemnified Party or Indemnified Person
which relates to such action or claim. The indemnifying party shall keep the
Indemnified Party or Indemnified Person apprised as to the status of the defense
or any settlement negotiations with respect thereto. No indemnifying party shall
be liable for any settlement of any action, claim or proceeding effected without
its prior written consent. No indemnifying party shall, without the prior
written consent of the Indemnified Party or Indemnified Person, consent to entry
of any judgment or enter into any settlement or other compromise which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party or Indemnified Person of a release from all liability
in respect of such claim or litigation. Following indemnification as provided
for hereunder, the indemnifying party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms
or corporations relating to the matter for which indemnification has been made.
The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not relieve such
indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 6, except to the extent that the indemnifying party is
prejudiced in its ability to defend such action.

         d.  The indemnification required by this Section 6 shall be made by
periodic payments of the amount thereof during the course of the investigation
or defense, as and when bills are received or Indemnified Damages are incurred.

         e.  The indemnity agreements contained herein shall be in addition to
(i) any cause of action or similar right of the Indemnified Party or Indemnified
Person against the indemnifying party or others, and (ii) any liabilities the
indemnifying party may be subject to pursuant to the law.

     7.  CONTRIBUTION.
         ------------

         To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no seller of Registrable Securities guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any seller of Registrable Securities who was not guilty of
fraudulent misrepresentation; and (ii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds received by
such seller from the sale of such Registrable Securities pursuant to such
Registration Statement.

     8.  REPORTS UNDER THE 1934 ACT.
         --------------------------

         With a view to making available to the Investors the benefits of Rule
144 promulgated under the 1933 Act or any other similar rule or regulation of
the SEC that may at any time permit the Investors to sell securities of the
Company to the public without registration ("Rule 144"), the Company agrees to:

         a.  make and keep public information available, as those terms are
understood and defined in Rule 144;

         b.  file with the SEC in a timely manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company remains subject to such requirements (it being understood that
nothing herein shall limit the Company's obligations under Section 4(c) of the
Securities Purchase Agreement) and the filing of such reports and other
documents is required for the applicable provisions of Rule 144; and

         c.  furnish to each Investor so long as such Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company that
it has complied with the reporting requirements of Rule 144, the 1933 Act and
the 1934 Act and (ii) such other information as may be reasonably requested to
permit the investors to sell such securities pursuant to Rule 144 without
registration.

     9.  ASSIGNMENT OF REGISTRATION RIGHTS.
         ---------------------------------

         The rights under this Agreement shall be automatically assignable by
the Investors to any transferee of all or any portion of Registrable Securities
in accordance with Section 2(f) of the Securities Purchase Agreement if: (i) the
Investor agrees in writing with the transferee or assignee to assign such
rights, and a copy of such agreement is furnished to the Company within a
reasonable time after such assignment; (ii) the Company is, within a  reasonable
time after such transfer or assignment, furnished with written notice of (a) the
name and address of such transferee or assignee, and (b) the securities with
respect to which such registration rights are being transferred or assigned;
(iii) immediately following such transfer or assignment the further disposition
of such securities by the transferee or assignee is restricted under the 1933
Act and applicable state securities laws; (iv) at or before the time the Company
receives the written notice contemplated by clause (ii) of this sentence the
transferee or assignee agrees in writing with the Company to be bound by all of
the provisions contained herein; and (v) such transfer shall have been made in
accordance with the applicable requirements of the Securities Purchase
Agreement. No transferee of registration rights under this Agreement shall be
entitled to include any Registrable Securities on a Registration Statement
unless it previously has provided the Company the written notice referred to in
clause (ii) of the preceding sentence.

     10. AMENDMENT OF REGISTRATION RIGHTS.
         --------------------------------

         Provisions 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 Investors who then hold at least two-thirds (2/3) of the principal amount of
the Notes which are then outstanding.  Any amendment or waiver effected in
accordance with this Section 10 shall be binding upon each Investor and the
Company.  No such amendment shall be effective to the extent that it applies to
less than all of the holders of the Registrable Securities.  No consideration
shall be offered or paid to any Person to amend or consent to a waiver or
modification of any provision of any of this Agreement unless the same
consideration also is offered to all of the parties to this Agreement.

     11. MISCELLANEOUS.
         -------------

         a.  A Person is deemed to be a holder of Registrable Securities
whenever such Person owns or is deemed to own of record such Registrable
Securities.  If the Company receives conflicting instructions, notices or
elections from two or more Persons with respect to the same Registrable
Securities, the Company shall act upon the basis of instructions, notice or
election received from the registered owner of such Registrable Securities.

         b.  Any notices, consents, waivers or other communications required or
permitted to be given under the terms of this Agreement must be in writing and
will be deemed to have been delivered:  (i) upon receipt, when delivered
personally; (ii) upon receipt, when sent by facsimile (provided confirmation of
transmission is mechanically or electronically generated and kept on file by the
sending party); or (iii) one business day after deposit with a nationally

party to receive the same.  The addresses and facsimile numbers for such

Attn:________________

          Re:  Blue Rhino Corporation
               ----------------------

Ladies and Gentlemen:

     We are counsel to Blue Rhino Corporation, a Delaware corporation (the
"Company"), and have represented the Company in connection with that certain
Securities Purchase Agreement (the "Purchase Agreement") entered into by and
among the Company and the Buyer named therein (collectively, the "Holders")
pursuant to which the Company issued to the Holders of convertible notes (the
"Notes") convertible into shares of the Company's common stock, par value $.001
per share (the "Common Stock") and the related Warrants (the "Warrants") to
acquire shares of Common Stock.  Pursuant to the Purchase Agreement, the Company
also has entered into a Registration Rights Agreement with the Holders (the
"Registration Rights Agreement") pursuant to which the Company agreed, among
other things, to register the Registrable Securities (as defined in the
Registration Rights Agreement), including the shares of Common Stock issuable
upon conversion of the Notes and exercise of the Warrants, under the Securities
Act of 1933, as amended (the "1933 Act").  In connection with the Company's
obligations under the Registration Rights Agreement, on ____________ ____,  the
Company filed a Registration Statement on Form S-3 (File No. 333-_____________)
(the "Registration Statement") with the Securities and Exchange Commission (the
"SEC") relating to the Registrable Securities which names each of the Holders as
a selling stockholder thereunder.

     In connection with the foregoing, we advise you that a member of the SEC's
staff has advised us by telephone that the SEC has entered an order declaring
the Registration Statement effective under the 1933 Act at [ENTER TIME OF
EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after
telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

                                   Very truly yours,

                                   [ISSUER'S COUNSEL]

                                                                     EXHIBIT 4.3


                            BLUE RHINO CORPORATION
                              FIRST AMENDMENT TO
              AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT


     THIS FIRST AMENDMENT TO THE AMENDED AND RESTATED REGISTRATION RIGHTS
AGREEMENT (this "Amendment") is dated as of September 7, 1999 by and among BLUE
RHINO CORPORATION, a Delaware corporation (the "Corporation"), the Persons
listed on Schedule 1 attached hereto  who are showing on the records of the
          ----------
Corporation as holders of Registrable Shares as of the date of the amendment and
restatement of this Agreement (collectively, the "Purchasers").   This Amendment
amends  that certain Registration Rights Agreement dated December 1, 1994, as
amended and restated by that certain Amended and Restated Registration Rights
Agreement dated March 1, 1997.

                                   RECITALS:

     A.   Purchasers are the record holders of unregistered shares of the
Corporation's Common Stock which are Registrable Shares subject to the Agreement
and which were issued upon the conversion of the Corporation's Series A
Convertible  Participating Preferred Stock (the "Series A Preferred Shares"),
the Common Shares and Old Warrants in connection with the Corporation's initial
public offering in May 1998.

     B.   The Corporation and Purchasers deem it desirable to enter into this
Amendment.


                                  AGREEMENTS

     In consideration of the premises and the mutual covenants herein contained
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto hereby agree as follows:

     1.   Definitions.   The definition of "Registrable Securities" is hereby
          ------------
amended as follows:

     "Registrable Shares" means at any time (i) any shares of Common Stock then
outstanding which were issued upon conversion of the Securities; (ii) any shares
of Common Stock then issuable upon conversion or exercise of the then
outstanding Securities; (iii) the Common Shares; (iv) the  September 1999 Common
Shares (v) any shares of Common Stock then outstanding which were issued as, or
were issued directly or indirectly upon the conversion or exercise of other
securities issued as, a dividend or other distribution with respect or in
replacement of any shares referred to in (i), (ii), (iii) or (iv); and (v) any
shares of Common Stock then issuable directly or indirectly upon the conversion
or exercise of other securities which were issued as a dividend or other
distribution with respect to or in replacement of any shares referred to in (i),

include any shares which have been registered pursuant to the Securities Act,
which have been sold to the public pursuant to Rule 144 of the Commission under
the Securities Act ("Rule 144"), for which certificates for such securities not

such Registrable Shares (by conversion or otherwise), whether or not such
acquisition actually has been effected.

                                    WARRANT

                                Series - 1999-A

   To Purchase ________ Shares of Common Stock (Subject to adjustment herein)

                          Expiring September __, 2004


     THIS IS TO CERTIFY THAT, for value received, _____________________
("Original Warrantholder") or his respective registered assign is entitled to
purchase from Blue Rhino Corporation, a Delaware corporation (the "Company"), at
any time and from time to time prior to 5:00 P.M., Winston-Salem, North Carolina
time, on September __, 2004, at the principal office of the Company which is
currently 104 Cambridge Plaza Drive, Winston-Salem, North Carolina 27104 (or
such other address as the Company shall specify by notice to the Holder) at the
Exercise Price, the number of shares of Common Stock, with a par value of $0.001
per share (the "Common Stock"), of the Company shown above, all subject to
adjustment and upon the terms and conditions as hereinafter provided, and is
entitled also to exercise the other appurtenant rights, powers and privileges
hereinafter described.

     Certain terms used in this Warrant are defined in Article V.

                                   ARTICLE I

                              EXERCISE OF WARRANTS

     1.1  Method of Exercise and Payment.
          ------------------------------

          (a) Method of Exercise.  To exercise this Warrant in whole or in part,
the registered holder of this Warrant (the "Holder") shall deliver to the
Company on or prior to 5:00 P.M., Winston-Salem, North Carolina time, on
September __, 2004, at the principal office of the Company, (a) this Warrant,
(b) a written notice, in substantially the form of the subscription notice (the
"Subscription Notice") attached hereto, of such Holder's election to exercise
this Warrant, which notice shall specify the number of shares of Common Stock to
be purchased or converted into, as the case may be, the denominations of the
share certificate or certificates desired and the name or names in which such
certificates are to be registered, and (c) payment to the Company of the amount
equal to the product of the then applicable Exercise Price multiplied by the
number of shares of Common Stock then being purchased pursuant to one of the
payment methods permitted under Section 1.1(b) below.

          (b) Method of Payment.  Payment shall be made either (1) by cash,
money order, certified or bank cashier's check, (2) by wire transfer, (3) by
converting the Warrant, or any portion thereof, into Common Stock pursuant to
Section 1.1(c) below ("Warrant Conversion") or (4) any combination of the
foregoing at the option of the Holder.

          (c) Payment by Warrant Conversion.  Subject to any limitations set
forth in this Warrant, the Holder may exercise the purchase right represented by
this Warrant with respect to a particular number of shares of

<PAGE>

Common Stock subject to this Warrant and elect to pay for the Underlying Common
Stock through Warrant Conversion as defined in Section 1.1(b), by specifying
such election in the Subscription Notice. In such event, the Company shall
deliver to the Holder (without payment by the Holder of any Exercise Price or
any cash or other consideration) that number of shares of Common Stock equal to
the quotient obtained by dividing (x) the value of this Warrant (or the
specified portion hereof) on the Exercise Date, which value shall be determined
by subtracting (A) the aggregate Exercise Price of the Underlying Common Stock
immediately prior to the exercise of the Warrant from (B) the aggregate Fair
Market Value of the Underlying Common Stock issuable upon exercise of this
Warrant (or the specified portion hereof) on the Exercise Date, by (y) the Fair
Market Value of one share of Common Stock on the Exercise Date. For purposes of
this Section 1, "Fair Market Value" of a share of Common Stock as of a
particular date shall mean:

               (i) If the Company's Common Stock is Publicly Traded, then the
          fair market value of a share of Common Stock shall equal the Market
          Price as of the last Business Day immediately prior to the Exercise
          Date.  "Publicly Traded" shall mean such stock is listed on any
          national securities exchange (as defined in the Exchange Act) or
          quoted on NASDAQ.

              (ii)  If the Company stock is not Publicly Traded, then as
          determined in good faith by the Board of Directors upon review of the
          relevant factors.

          (d) Mechanics.  The Company shall, as promptly as practicable and in
any event within three days after delivery of a Subscription Notice as described
above, execute and deliver or cause to be executed and delivered, in accordance
with such Subscription Notice any payment of the Exercise Price, a certificate
or certificates representing the aggregate number of shares of Common Stock
specified in said Subscription Notice.  In the event the shares of Common Stock
issuable upon the Exercise of this Warrant may, in the opinion of counsel
acceptable to the Company, be issued without the legend set forth in Section 1.4
and the Holder requests that the shares be issued via electronic book entry
format, such issuance shall be deemed to satisfy the certificate delivery
requirements of this Section.   The share certificate or certificates so
delivered shall be in such denominations as may be specified in such
Subscription Notice or, if such Subscription Notice shall not specify
denominations, in denominations of 100 shares each, and shall be issued in the
name of the Holder or such other name or names as shall be designated in such
Subscription Notice.  Such certificate or certificates shall be deemed to have
been issued (and this Warrant or the portion thereof specified in the
Subscription Notice shall be deemed to have been exercised), and such Holder or
any other Person so designated to be named therein shall be deemed for all
purposes to have become a holder of record of such shares, as of the date the
aforementioned Subscription Notice is received by the Company, or delivery
thereof is refused (the "Exercise Date").  If this Warrant shall have been
exercised only in part, the Company shall, at the time of delivery of the
certificate or certificates, deliver to the Holder a new Warrant evidencing the
rights to purchase or convert the remaining shares of Common Stock called for by
this Warrant, which new Warrant shall in all other respects be identical with
this Warrant, or, at the request of the Holder, appropriate notation may be made
on this Warrant which shall then be refunded to the Holder.  The Company shall
pay all expenses, taxes and other charges payable in connection with the
preparation, issuance and delivery of share certificates and new Warrants,
except that, if share certificates or new Warrants shall be registered in a name
or names other than the name of the Holder, funds sufficient to pay all transfer
taxes payable as a result of such transfer shall be paid by the Holder at the
time of delivering the aforementioned notice of exercise or promptly upon
receipt of a written request of the Company for payment.

     1.2  Shares to Be Fully Paid and Nonassessable.  All shares of Common Stock
issued upon the exercise of this Warrant shall be validly issued, fully paid and
nonassessable and free from all preemptive rights of any stockholder, and from
all taxes, liens and charges with respect to the issue thereof (other than
transfer taxes).

     1.3  No Fractional Shares to Be Issued.  The Company shall not be required
to issue fractions of shares of Common Stock upon exercise of this Warrant.  If
any fraction of a share would, but for this Section, be issuable upon any
exercise of this Warrant, in lieu of such fractional share the Company may pay
to the Holder, in cash, an amount equal to such fraction of the fair market
value (as determined in good faith by the Board of Directors) per


                                       2
<PAGE>

share of outstanding Common Stock of the Company in the Business Day immediately
prior to the date of such exercise.

     1.4  Share Legends.  Each certificate for shares of Common Stock issued
upon exercise of this Warrant, unless at the time of exercise such shares are
registered under the Securities Act, shall bear the following legend:

          "This security has not been registered under the Securities Act of
          1933 and may not be sold or offered for sale unless registered
          pursuant to such Act or unless the holder hereof delivers to Blue
          Rhino Corporation an opinion of counsel reasonably acceptable to Blue
          Rhino Corporation stating that an exemption from such registration is
          available."

     Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon completion
of a public distribution pursuant to a registration statement under the
Securities Act) shall also bear such legend unless, in the opinion of counsel
selected by the holder of such certificate (who may be an employee of such
holder) and reasonably acceptable to the Company, the securities represented
thereby need no longer be subject to restrictions on resale under the Securities
Act.

     1.5  Reservation; Authorization.  The Company has reserved and will keep
available for issuance upon exercise of the Warrant the total number of shares
of Common Stock deliverable upon exercise of the Warrant from time to time
outstanding.  The issuance of the shares of Common Stock upon exercise of the
Warrant has been duly and validly authorized and, when issued and sold in
accordance with the Warrant, such shares of Common Stock will be duly and
validly issued, fully paid and nonassessable.  The Company will take all such
actions as are necessary in order to insure the foregoing.

     1.6  Result of Exercise.  On the Exercise Date the rights of the holder of
such Warrant as such holder will cease and the Person or Persons in whose name
or names any certificate or certificates for shares of Common Stock are to be
issued upon such exercise will be deemed to have become the holder or holders of
record of the shares of Common Stock represented thereby.

     1.7  Not Close Books Until Exercise.  The Company will not close its books
against the transfer of this Warrant or shares of Common Stock issued or
issuable upon exercise of this Warrant in any manner which interferes with the
timely exercise of this Warrant.

                                   ARTICLE II

                             TRANSFER, EXCHANGE AND
                             REPLACEMENT OF WARRANT

     2.1  Ownership of Warrant.  The Company may deem and treat the Person in
whose name this Warrant is registered as the holder and owner hereof for all
purposes and shall not be affected by any notice to the contrary, until this
Warrant is presented for registration of transfer as provided in this Article
II.

     2.2  Transfer of Warrant.  The Company agrees to maintain books for the
registration of transfers of the Warrant, and any transfer, in whole or in part,
of this Warrant and all rights hereunder shall be registered on such books, upon
surrender of this Warrant at the principal office of the Company together with a
written assignment of this Warrant duly executed by the Holder or his, her or
its duly authorized agent or attorney.  The Warrant is transferable pursuant to
(i) public offerings registered under the Securities Act, and (ii) Rule 144 of
the Commission (or any similar rule then in force) if such rule is available.

     2.3  Division or Combination of Warrant.  This Warrant may be divided or
combined with other Warrants upon surrender hereof and of any Warrant or
Warrants with which this Warrant is to be combined at the Company, together with
a written notice specifying the names and denominations in which the new Warrant
or


                                       3
<PAGE>

Warrants are to be issued, signed by the holders hereof and thereof or their
respective duly authorized agents or attorneys.  Subject to compliance with
Section 2.2 as to any transfer which may be involved in the division or
combination, the Company shall execute and deliver a new Warrant or Warrants in
exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice.

     2.4  Loss, Theft, Destruction of Warrant Certificates.  Upon receipt of
evidence reasonably satisfactory to the Company (an affidavit of the registered
holder will be satisfactory) of the loss, theft, destruction or mutilation of
any Warrant and, in the case of any such loss, theft or destruction upon receipt
of indemnity or security reasonably satisfactory to the Company, or, in the case
of any such mutilation, upon surrender and cancellation of such Warrant, the
Company will (at its expense) make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same aggregate number of shares of Common Stock.

     2.5  Expenses of Delivery of Warrant.  The Company shall pay all expenses,
taxes (other than transfer taxes) and other charges payable in connection with
the preparation, issuance and delivery of Warrant and Underlying Common Stock
hereunder.  If, pursuant to Section 2.2, the opinion of counsel provides that
registration is not required for the proposed exercise or transfer of this
Warrant or the proposed transfer of the Underlying Common Stock and that the
proposed exercise or transfer in the absence of registration would require the
Company to take any action including executing and filing forms or other
documents with the Commission or any state securities agency, or delivering to
the Holder any form or document in order to establish the right of the Holder to
effectuate the proposed exercise or transfer, the Company agrees promptly, at
its expense, to take any such action; and provided, further, that the Company
will reimburse the Holder in full for any expenses (including but not limited to
the fees and disbursements of such counsel, but excluding brokers' commissions)
incurred by the Holder or owner of Underlying Common Stock on his, her or its
behalf in connection with such exercise or transfer of the Warrant or transfer
of Underlying Common Stock.

                                  ARTICLE III

                            ANTIDILUTION PROVISIONS

     3.1  Adjustments Generally.  The Exercise Price and the number of shares of
Common Stock (or other securities or property) issuable upon exercise of this
Warrant shall be subject to adjustment from time to time upon the occurrence of
certain events, as provided in this Article III.

     3.2  Exercise of Warrant.  At any time and from time to time, any holder of
this Warrant may exercise all or any portion of this Warrant into the number of
shares of Common Stock computed by (i) multiplying the number of shares of
Common Stock sought to be purchased pursuant to this Warrant by the Exercise
Price set forth in Section 3.3(a) and (ii) dividing the resulting product by the
Exercise Price then in effect.

     3.3  Exercise Price.  The "Exercise Price" shall be equal to 115% per share
of the Common Stock purchased by the Holder in connection with the Holder's
acquisition of this Warrant.  In order to prevent dilution of the exercise
rights granted to the Holder the Exercise Price will be subject to adjustment
from time to time pursuant to this Section 3.4 and 3.5 below.

     3.4  Subdivision or Combination of Common Stock.  If the Company at any
time subdivides (by any stock split, stock dividend, recapitalization or
otherwise) or combines (by reverse stock split or otherwise)  one or more
classes of its outstanding shares of Common Stock into a greater number of
shares, the Exercise Price in effect immediately prior to such subdivision or
combination will be adjusted by the same factor by which the Company subdivided
or combined the Common Stock so that through the application of Section 3.2, the
total number of shares of Common Stock which such Holder may purchase upon the
exercise of this Warrant shall equal the number of shares such Holder would own
had such Holder exercised this Warrant immediately prior to such
recapitalization, subdivision or combination and the Exercise Price multiplied
by the number of Underlying Common Shares shall be equal before and after such
subdivision or combination.

     3.5  Organic Change.  Prior to the consummation of any Organic Change, the
Company will make appropriate provisions to insure that the Holder of this
Warrant will thereafter have the right to acquire and receive, in lieu of or in
addition to the shares of Common Stock immediately theretofore acquirable and
receivable upon the exercise of this Warrant, such shares of stock, securities
or assets as such holder would have received in connection with such Organic
Change if the Holder had exercised this Warrant immediately prior to such
Organic Change. In any such case, the Company will make appropriate provisions
to insure that the provisions of this Section 3.5 will thereafter be applicable
to this Warrant (including, an immediate adjustment of the Exercise Price to the
value for the Common Stock reflected by the terms of such Organic Change and a
corresponding immediate adjustment in the number of shares of Common Stock
acquirable and receivable upon exercise of this Warrant, if the value so
reflected is less than the Exercise Price in effect immediately prior to such
Organic Change).  The Company will not effect any such Organic Change, unless
prior to the consummation thereof, the successor Company resulting from such
Organic Change assumes by written instrument, the obligation to deliver to each
such holder such shares of stock, securities or assets as, in accordance with
the foregoing provisions, such holder may be entitled to acquire.

     All other terms of this Warrant shall remain in full force and effect
following such an Organic Change. The provisions of this Section 3.5 shall
similarly apply to successive Organic Changes.

     3.6  Notices.
          -------

          (a) Immediately upon any adjustment of the Exercise Price, the Company
shall give written notice thereof to the Holder of this Warrant specifying the
Exercise Price in effect thereafter with respect to the particular holder.

          (b) The Company shall give written notice to the Holder of this
Warrant at least 20 days prior to the date on which the Company closes its books
or takes a record for determining rights to vote with respect to any Organic
Change, Change in Ownership, Fundamental Change or other reorganization,
dissolution or liquidation.  The Company shall also give written notice to the
Holder of this Warrant at least 20 days prior to the date on which any Organic
Change, Change in Ownership, Fundamental Change or other reorganization,
dissolution or liquidation shall occur.

     3.7  Certain Other Events.  The Company will not, by amendment of its
certificate of incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issues or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of this Warrant, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the Holder against
dilution or other impairment.  If any event occurs as to which the foregoing
provisions of this Article III are not strictly applicable or, if strictly
applicable, would not, in the good faith judgment of the Board of Directors,
fairly protect the purchase rights of this Warrant in accordance with the
essential intent and principles of such provisions, then the Board of Directors
shall make such adjustments in the application of such provisions, in accordance
with such essential intent and principles, as shall be reasonably necessary, in
the good faith opinion of the Board of Directors, to protect such purchase
rights as aforesaid, but in no event shall any such adjustment have the effect
of increasing the Exercise Price or decreasing the number of shares of Common
Stock subject to purchase upon exercise of this Warrant.

     3.8  Proceedings Prior to Any Action Requiring Adjustment.  As a condition
precedent to the taking of any action which would require an adjustment pursuant
to this Article III, the Company shall take any action which may be necessary,
including obtaining regulatory approvals or exemptions, in order that the
Company may thereafter validly and legally issue as fully paid and nonassessable
all shares of Common Stock which the Holder of this Warrant is entitled to
receive upon exercise thereof, and if all such approvals and actions are not
taken, the Company shall take any action which would cause the Company to be
able to issue to the Holder of this Warrant the full number of shares issuable
upon exercise hereof in accordance with the terms hereof.

     4.1  Liquidation or Dissolution.  In case the Company at any time while
this Warrant shall remain unexpired and unexercised, shall dissolve, liquidate,
or wind up its affairs other than in connection with an Organic Change, the
Holder shall have the right to exercise this Warrant for a period of sixty (60)
days after the later of (i) such event having occurred and (ii) receipt by the
Holder of a notice from the Company indicating the kind and amount of securities
or assets issuable or distributable to holders of shares of Common Stock with
respect to such event, and upon exercise of this Warrant during such period, the
Holder shall have the right to receive in lieu of each share of the Underlying
Common Stock, 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 of the shares of the Common Stock.

Warrant No.:__________________                         Number of Shares: _______
Date of Issuance: _________ __, _____


Blue Rhino Corporation, a Delaware corporation (the "Company"), hereby certifies
that, for Ten United States Dollars ($10.00) and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
____________________, the registered holder hereof or its permitted assigns, is
entitled, subject to the terms set forth below, to purchase from the Company
upon surrender of this Warrant, at any time or times on or after the date
hereof, but not after 11:59 P.M. Eastern Time on the Expiration Date (as defined
herein)__________ (___) fully paid nonassessable shares of Common Stock (as
defined herein) of the Company (the "Warrant Shares") at the purchase price per
share provided in Section 1(b) below; provided, however, that in no event shall
the holder be entitled to exercise this Warrant for a number of Warrant Shares
in excess of that number of Warrant Shares which, upon giving effect to such
exercise, would cause the aggregate number of shares of Common Stock
beneficially owned by the holder and its affiliates to exceed 4.99% of the
outstanding shares of the Common Stock following such exercise. For purposes of
the foregoing proviso, the aggregate number of shares of Common Stock
beneficially owned by the holder and its affiliates shall include the number of
shares of Common Stock issuable upon exercise of this Warrant with respect to
which the determination of such proviso is being made, but shall exclude shares
of Common Stock which
<PAGE>

beneficially owned by the holder and its affiliates and (ii) exercise or
conversion of the unexercised or unconverted portion of any other securities of
the Company beneficially owned by the holder and its affiliates (including,
without limitation, any convertible notes or preferred stock) subject to a
limitation on conversion or exercise analogous to the limitation contained
herein. Except as set forth in the preceding sentence, for purposes of this
paragraph, beneficial ownership shall be calculated in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this
Warrant, in determining the number of outstanding shares of Common Stock a
holder may rely on the number of outstanding shares of Common Stock as reflected
in (1) the Company's most recent Form 10-Q or Form 10-K, as the case may be, (2)
a more recent public announcement by the Company or (3) any other notice by the
Company or its transfer agent setting forth the number of shares of Common Stock
outstanding. Upon the written request of any holder, the Company shall promptly,
but in no event later than one (1) Business Day following the receipt of such
notice, confirm in writing to any such holder the number of shares of Common
Stock then outstanding. In any case, the number of outstanding shares of Common
Stock shall be determined after giving effect to conversions of the Notes (as
defined below) and exercise of Warrants (as defined below) by such holder and
its affiliates since the date as of which such number of outstanding shares of
Common Stock was reported.

     Section 2.  Exercise of Warrant.
                 -------------------

          (a)    Subject to the terms and conditions hereof, this Warrant may be
exercised by the holder hereof then registered on the books of the Company, in
whole or in part, at any time on any Business Day on or after the opening of
business on the date hereof and prior to 11:59 P.M. Eastern Time on the
Expiration Date by (i) delivery of a written notice, in the form of the
subscription notice attached as Exhibit A hereto (the "Exercise Notice"), of
                                ---------
such holder's election to exercise this Warrant, which notice shall specify the
number of Warrant Shares to be purchased, (ii) (A) payment to the Company of an
amount equal to the applicable Warrant Exercise Price multiplied by the number
of Warrant Shares as to which this Warrant is being exercised (plus any
applicable issue or transfer taxes) (the "Aggregate Exercise Price") in cash or
wire transfer of immediately available funds or (B) by notifying the Company
that this Warrant is being exercised pursuant to a Cashless Exercise (as defined
in Section 2(e)) and (iii) the surrender to a common carrier for overnight
delivery to the Company as soon as practicable following such date, this Warrant
(or an indemnification undertaking with respect to this Warrant in the case of
its loss, theft or destruction); provided, that if such Warrant Shares are to be
issued in any name other than that of the registered holder of this Warrant,
such issuance shall be deemed a transfer and the provisions of Section 7 shall
be applicable.  In the event of any exercise of the rights represented by this
Warrant in compliance with this Section 2(a), the Company shall on the second
Business Day following the date of receipt of the Exercise Notice, the Aggregate
Exercise Price (or notice of a Cashless Exercise) and this Warrant (or an
indemnification undertaking with respect to this Warrant in the case of its
loss, theft or destruction) (the "Exercise Delivery Documents"), credit such
aggregate number of shares of Common Stock to which the holder shall be entitled
to the holder's or its designee's balance account with The Depository Trust
Company; provided, however, if the holder who submitted the Exercise Notice
requested physical delivery of any or all of the Warrant Shares and such shares
cannot be delivered via the Depository Trust Company, then the Company shall, on
or before the second Business Day following receipt of the Exercise Delivery
Documents issue and surrender to a common carrier for overnight delivery to the
address specified in the Exercise Notice, a certificate, registered in the name
of the holder,

                                      -5-
<PAGE>

for the number of shares of Common Stock to which the holder shall be entitled
pursuant to such request. Upon delivery of the Exercise Notice and Aggregate
Exercise Price referred to in clause (ii)(A) above or notification to the
Company of a Cashless Exercise referred to in Section 2(e), the holder of this
Warrant shall be deemed for all corporate purposes to have become the holder of
record of the Warrant Shares with respect to which this Warrant has been
exercised, irrespective of the date of delivery of this Warrant as required by
clause (iii) above or the certificates evidencing such Warrant Shares. In the
case of a dispute as to the determination of the Warrant Exercise Price, the
Closing Sale Price or the Closing Bid Price of a security or the arithmetic
calculation of the Warrant Shares, the Company shall promptly issue to the
holder the number of shares of Common Stock that is not disputed and shall
submit the disputed determinations or arithmetic calculations to the holder via
facsimile within one Business Day of receipt of the holder's subscription
notice. If the holder and the Company are unable to agree upon the determination
of the Warrant Exercise Price, the Closing Sale Price or Closing Bid Price or
arithmetic calculation of the Warrant Shares within one day of such disputed
determination or arithmetic calculation being submitted to the holder, then the
Company shall immediately submit via facsimile (i) the disputed determination of
the Warrant Exercise Price, Closing Sale Price or the Closing Bid Price to an
independent, reputable investment banking firm or (ii) the disputed arithmetic
calculation of the Warrant Shares to its independent, outside accountant. The
Company shall cause the investment banking firm or the accountant, as the case
may be, to perform the determinations or calculations and notify the Company and
the holder of the results no later than two (2) Business Days from the time it
receives the disputed determinations or calculations. Such investment banking
firm's or accountant's determination or calculation, as the case may be, shall
be deemed conclusive absent manifest error.

          (b)  Unless the rights represented by this Warrant shall have expired
or shall have been fully exercised, the Company shall, as soon as practicable
and in no event later than five Business Days after any exercise and at its own
expense, issue a new Warrant identical in all respects to the Warrant exercised
except it shall represent rights to purchase the number of Warrant Shares
purchasable immediately prior to such exercise under the Warrant exercised, less
the number of Warrant Shares with respect to which such Warrant is exercised.

          (c)  No fractional shares of Common Stock are to be issued upon the
exercise of this Warrant, but rather the number of shares of Common Stock issued
upon exercise of this Warrant shall be rounded up or down to the nearest whole
number.

          (d)  Intentionally left blank.

                                      -6-
<PAGE>

          (e)  Notwithstanding anything contained herein to the contrary and in
addition to and not in lieu of any of the other rights and remedies to which the
holder may be entitled by reason of the Company's failure fully to meet its
obligations under the Securities Purchase Agreement or the Registration Rights
Agreement, the holder of this Warrant may, at its election exercised in its sole
discretion, exercise this Warrant in whole or in part and, in lieu of making the
cash payment otherwise contemplated to be made to the Company upon such exercise
in payment of the Aggregate Exercise Price, elect instead to receive upon such
exercise the "Net Number" of shares of Common Stock determined according to the
following formula (a "Cashless Exercise"):

     Net Number = (A x B) - (A x C)
                  -----------------
                          B
          For purposes of the foregoing formula:

               A= the total number shares with respect to which this Warrant is
               then being exercised.

               B= the Closing Sale Price of the Common Stock on the date
               immediately preceding the date of the subscription notice.

               C= the Warrant Exercise Price then in effect for the applicable
               Warrant Shares at the time of such exercise.

     Section 3.  Covenants as to Common Stock.  The Company hereby covenants and
                 ----------------------------
agrees as follows:

          (a)  This Warrant is, and any Warrants issued in substitution for or
replacement of this Warrant will upon issuance be, duly authorized and validly
issued.

          (b)  All Warrant Shares which may be issued upon the exercise of the
rights represented by this Warrant in conformity with the terms of this Warrant
will, upon issuance, be validly issued, fully paid and nonassessable and free
from all taxes, liens and charges with respect to the issue thereof.

                                      -7-
<PAGE>

          (c)  During the period within which the rights represented by this
Warrant may be exercised, the Company will at all times have authorized and
reserved at least 100% of the number of shares of Common Stock needed to provide
for the exercise of the rights then represented by this Warrant and the par
value of said shares will at all times be less than or equal to the applicable
Warrant Exercise Price.

          (d)  The Company shall promptly secure the listing of the shares of
Common Stock issuable upon exercise of this Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed (subject to official notice of issuance upon
exercise of this Warrant) and shall maintain, so long as any other shares of
Common Stock shall be so listed, such listing of all shares of Common Stock from
time to time issuable upon the exercise of this Warrant; and the Company shall
so list on each national securities exchange or automated quotation system, as
the case may be, and shall maintain such listing of, any other shares of capital
stock of the Company issuable upon the exercise of this Warrant if and so long
as any shares of the same class shall be listed on such national securities
exchange or automated quotation system.

          (e)  The Company will not, by amendment of its Certificate of
Incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other impairment, consistent with the tenor and purpose of
this Warrant.  No impairment of the preferences and rights contained in the
Company's Notes or any waiver thereof which has an adverse effect on the rights
granted hereunder shall be given effect until the Company has taken appropriate
action (satisfactory to the holders of Note Warrants representing a majority of
the shares of Common Stock issuable upon the exercise of such Note Warrants then
outstanding) to avoid such adverse effect with respect to this Warrant.  Without
limiting the generality of the foregoing, the Company (i) will not increase the
par value of any shares of Common Stock receivable upon the exercise of this
Warrant above the Warrant Exercise Price then in effect, and (ii) will take all
such actions as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and nonassessable shares of Common Stock
upon the exercise of this Warrant.

          (f)  This Warrant will be binding upon any entity succeeding to the
Company by merger, consolidation or acquisition of all or substantially all of
the Company's assets.

     Section 4.  Taxes.  The Company shall pay any and all taxes which may be
                 -----
payable with respect to the issuance and delivery of Warrant Shares upon
exercise of this Warrant (but no income, capital gain, estate or other taxes
applicable to the holder resulting from any profits realized upon such
exercise); provided, however, that the Company shall not be required to pay any
tax that may be payable in respect of any transfer involved in the issue or
delivery of Common Stock or other securities or property in a name other than
that of the registered holders

                                      -8-
<PAGE>

of this Warrant to be converted and such holder shall pay such amount, if any,
to cover any applicable transfer or similar tax.

     Section 5.  Warrant Holder Not Deemed a Stockholder.  Except as otherwise
                 ---------------------------------------
specifically provided herein, no holder, as such, of this Warrant shall be
entitled to vote or receive dividends or be deemed the holder of shares of the
Company for any purpose, nor shall anything contained in this Warrant be
construed to confer upon the holder hereof, as such, any of the rights of a
stockholder of the Company or any right to vote, give or withhold consent to any
corporate action (whether any reorganization, issue of stock, reclassification
of stock, consolidation, merger, conveyance or otherwise), receive notice of
meetings, receive dividends or subscription rights, or otherwise, prior to the
issuance to the holder of this Warrant of the Warrant Shares which he or she is
then entitled to receive upon the due exercise of this Warrant.  In addition,
nothing contained in this Warrant shall be construed as imposing any liabilities
on such holder to purchase any securities (upon exercise of this Warrant or
otherwise) or as a stockholder of the Company, whether such liabilities are
asserted by the Company or by creditors of the Company.  Notwithstanding this
Section 5, the Company will provide the holder of this Warrant with copies of
the same notices and other information given to the stockholders of the Company
generally, contemporaneously with the giving thereof to the stockholders.

     Section 6.  Representations of Holder.  The holder of this Warrant, by the
                 -------------------------
acceptance hereof, represents that it is acquiring this Warrant and the Warrant
Shares for its own account for investment only and not with a view towards, or
for resale in connection with, the public sale or distribution of this Warrant
or the Warrant Shares, except pursuant to sales registered or exempted under the
Securities Act; provided, however, that by making the representations herein,
the holder does not agree to hold this Warrant or any of the Warrant Shares for
any minimum or other specific term and reserves the right to dispose of this
Warrant and the Warrant Shares at any time in accordance with or pursuant to a
registration statement or an exemption under the Securities Act.  The holder of
this Warrant further represents, by acceptance hereof, that, as of this date,
such holder is an  "accredited investor" as such term is defined in Rule
501(a)(1) of Regulation D promulgated by the Securities and Exchange Commission
under the Securities Act (an "Accredited Investor").  Upon exercise of this
Warrant, other than pursuant to a Cashless Exercise the holder shall, if
requested by the Company, confirm in writing, in a form satisfactory to the
Company, that the Warrant Shares so purchased are being acquired solely for the
holder's own account and not as a nominee for any other party, for investment,
and not with a view toward distribution or resale and that such holder is an
Accredited Investor.  If such holder cannot make such representations because
they would be factually incorrect, it shall be a condition to such holder's
exercise of this Warrant that the Company receive such other representations as
the Company considers reasonably necessary to assure the Company that the
issuance of its securities upon exercise of this Warrant shall not violate any
United States or state securities laws.

     Section 7.  Ownership and Transfer.
                 ----------------------

          (a)  The Company shall maintain at its principal executive offices (or
such other office or agency of the Company as it may designate by notice to the
holder hereof), a register for

                                      -9-
<PAGE>

this Warrant, in which the Company shall record the name and address of the
person in whose name this Warrant has been issued, as well as the name and
address of each transferee. The Company may treat the person in whose name any
Warrant is registered on the register as the owner and holder thereof for all
purposes, notwithstanding any notice to the contrary, but in all events
recognizing any transfers made in accordance with the terms of this Warrant.

          (b)  This Warrant and the rights granted hereunder shall be assignable
in compliance with all federal securities and blue sky laws by the holder hereof
without the consent of the Company.

          (c)  The Company is obligated to register the Warrant Shares for
resale under the Securities Act pursuant to the Registration Rights Agreement
dated September 22, 1999 by and between the Company and the Buyer listed on the
signature page thereto (the "Registration Rights Agreement") and the initial
holder of this Warrant (and certain assignees thereof) is entitled to the
registration rights in respect of the Warrant Shares as set forth in the
Registration Rights Agreement.

     Section 8.  Adjustment of Warrant Exercise Price and Number of Shares.  The
                 ---------------------------------------------------------
Warrant Exercise Price and the number of shares of Common Stock issuable upon
exercise of this Warrant shall be adjusted from time to time as follows:

          (a)  Adjustment of Warrant Exercise Price and Number of Shares upon
               --------------------------------------------------------------
Issuance of Common Stock.  If and whenever on or after the date of issuance of
- ------------------------
this Warrant, the Company issues or sells, or is deemed to have issued or sold,
any shares of Common Stock (other than shares of Common Stock deemed to have
been issued by the Company in connection with an Approved Stock Plan or upon
exercise or conversion of the Other Securities) for a consideration per share
less than a price (the "Applicable Price") equal to the Warrant Exercise Price
in effect immediately prior to such issuance or sale, then immediately after
such issue or sale the Warrant Exercise Price then in effect shall be reduced to
an amount equal to such consideration per share.  Upon each such adjustment of
the Warrant Exercise Price hereunder, the number of shares of Common Stock
acquirable upon exercise of this Warrant shall be adjusted to the number of
shares determined by multiplying the Warrant Exercise Price in effect
immediately prior to such adjustment by the number of shares of Common Stock
acquirable upon exercise of this Warrant immediately prior to such adjustment
and dividing the product thereof by the Warrant Exercise Price resulting from
such adjustment.

          (b)  Effect on Warrant Exercise Price of Certain Events.  For purposes
               --------------------------------------------------
of determining the adjusted Warrant Exercise Price under Section 8(a) above, the
following shall be applicable:

               (i)  Issuance of Options. If the Company in any manner grants any
                    -------------------
Options and the lowest price per share for which one share of Common Stock is
issuable upon the exercise of any such Option or upon conversion or exchange of
any Convertible Securities issuable upon exercise of any such Option is less
than the Applicable Price, then such share of Common

                                      -10-
<PAGE>

Stock shall be deemed to be outstanding and to have been issued and sold by the
Company at the time of the granting or sale of such Option for such price per
share. For purposes of this Section 8(b)(i), the Alowest price per share for
which one share of Common Stock is issuable upon exercise of such Options or
upon conversion or exchange of such Convertible Securities shall be equal to
the sum of the lowest amounts of consideration (if any) received or receivable
by the Company with respect to any one share of Common Stock upon the granting
or sale of the Option, upon exercise of the Option and upon conversion or
exchange of any Convertible Security issuable upon exercise of such Option. No
further adjustment of the Warrant Exercise Price shall be made upon the actual
issuance of such Common Stock or of such Convertible Securities upon the
exercise of such Options or upon the actual issuance of such Common Stock upon
conversion or exchange of such Convertible Securities. Notwithstanding the
foregoing, no adjustment shall be made pursuant to this Section 8(b)(i) to the
extent that such adjustment is based solely on the fact that the Convertible
Securities issuable upon exercise of such Option are convertible into or
exchangeable for Common Stock at a price which varies with the market price of
the Common Stock.

               (ii)   Issuance of Convertible Securities. If the Company in any
                      ----------------------------------
manner issues or sells any Convertible Securities and the lowest price per share
for which one share of Common Stock is issuable upon such conversion or exchange
thereof is less than the Applicable Price, then such share of Common Stock shall
be deemed to be outstanding and to have been issued and sold by the Company at
the time of the issuance or sale of such Convertible Securities for such price
per share. For the purposes of this Section 8(b)(ii), the Alowest price per
share for which one share of Common Stock is issuable upon such conversion or
exchange@ shall be equal to the sum of the lowest amounts of consideration (if
any) received or receivable by the Company with respect to one share of Common
Stock upon the issuance or sale of the Convertible Security and upon conversion
or exchange of such Convertible Security. No further adjustment of the Warrant
Exercise Price shall be made upon the actual issuance of such Common Stock upon
conversion or exchange of such Convertible Securities, and if any such issue or
sale of such Convertible Securities is made upon exercise of any Options for
which adjustment of the Warrant Exercise Price had been or are to be made
pursuant to other provisions of this Section 8(b), no further adjustment of the
Warrant Exercise Price shall be made by reason of such issue or sale.
Notwithstanding the foregoing, no adjustment shall be made pursuant to this
Section 8(b)(ii) to the extent that such adjustment is based solely on the fact
that such Convertible Securities are convertible into or exchangeable for Common
Stock at a price which varies with the market price of the Common Stock.

               (iii)  Change in Option Price or Rate of Conversion. If the
                      --------------------------------------------
purchase price provided for in any Options, the additional consideration, if
any, payable upon the issue, conversion or exchange of any Convertible
Securities, or the rate at which any Convertible Securities are convertible into
or exchangeable for Common Stock changes at any time, the Warrant Exercise Price
in effect at the time of such change shall be adjusted to the Warrant Exercise
Price which would have been in effect at such time had such Options or
Convertible Securities provided for such changed purchase price, additional
consideration or changed conversion rate, as the case may be, at the time
initially granted, issued or sold and the number

                                     -11-
<PAGE>

of shares of Common Stock acquirable hereunder shall be correspondingly
readjusted. For purposes of this Section 8(b)(iii), if the terms of any Option
or Convertible Security that was outstanding as of the date of issuance of this
Warrant are changed in the manner described in the immediately preceding
sentence, then such Option or Convertible Security and the Common Stock deemed
issuable upon exercise, conversion or exchange thereof shall be deemed to have
been issued as of the date of such change. No adjustment pursuant to this
Section 8(b) shall be made if such adjustment would result in an increase of the
Warrant Exercise Price then in effect.

          (c)  Effect on Warrant Exercise Price of Certain Events.  For purposes
of determining the adjusted Warrant Exercise Price under Sections 8(a) and 8(b),
the following shall be applicable:

               (i)    Calculation of Consideration Received. In case any Option
is issued in connection with the issue or sale of other securities of the
Company, together comprising one integrated transaction in which no specific
consideration is allocated to such Options by the parties thereto, the Options
will be deemed to have been issued for a consideration of $.01. If any Common
Stock, Options or Convertible Securities are issued or sold or deemed to have
been issued or sold for cash, the consideration received therefor will be deemed
to be the net amount of cash received by the Company therefor. If any Common
Stock, Options or Convertible Securities are issued or sold for a consideration
other than cash, the amount of such consideration received by the Company will
be the fair value of such consideration, except where such consideration
consists of securities, in which case the amount of consideration received by
the Company will be the average of the Closing Bid Price of such securities for
the ten (10) consecutive trading days immediately preceding the date of receipt.
If any Common Stock, Options or Convertible Securities are issued to the owners
of the non-surviving entity in connection with any merger in which the Company
is the surviving entity, the amount of consideration therefor will be deemed to
be the fair value of such portion of the net assets and business of the non-
surviving entity as is attributable to such Common Stock, Options or Convertible
Securities, as the case may be. The fair value of any consideration other than
cash or securities will be determined by the Company and the holders of the Note
Warrants representing a majority of the shares of Common Stock obtainable upon
exercise of the Note Warrants then outstanding. If such parties are unable to
reach agreement within ten (10) days after the occurrence of an event requiring
valuation (the "VALUATION EVENT"), the fair value of such consideration will be
determined in good faith by the Board of Directors of the Company within five
Business Days after the tenth (10th) day following the Valuation Event. The
determination pursuant to the immediately preceding sentence made in good faith
by the Board of Directors of the Company shall be final and binding upon all
parties.

               (ii) Integrated Transactions.  In case any Option is issued in
                    -----------------------
connection with the issue or sale of other securities of the Company, together
comprising one integrated transaction in which no specific consideration is
allocated to such Options by the parties thereto, the Options will be deemed to
have been issued for a consideration of $.01.

                                     -12-
<PAGE>

               (iii)  Treasury Shares.  The number of shares of Common Stock
                      ---------------
outstanding at any given time does not include shares owned or held by or for
the account of the Company, and the disposition of any shares so owned or held
will be considered an issue or sale of Common Stock.

               (iv)   Record Date. If the Company takes a record of the holders
                      -----------
of Common Stock for the purpose of entitling them (1) to receive a dividend or
other distribution payable in Common Stock, Options or in Convertible Securities
or (2) to subscribe for or purchase Common Stock, Options or Convertible
Securities, then such record date will be deemed to be the date of the issue or
sale of the shares of Common Stock deemed to have been issued or sold upon the
declaration of such dividend or the making of such other distribution or the
date of the granting of such right of subscription or purchase, as the case may
be.

          (d)  Adjustment of Warrant Exercise Price upon Subdivision or
               --------------------------------------------------------
Combination of Common Stock. If the Company at any time after the date of
- ---------------------------
issuance of this Warrant subdivides (by any stock split, stock dividend,
recapitalization or otherwise) one or more classes of its outstanding shares of
Common Stock into a greater number of shares, any Warrant Exercise Price in
effect immediately prior to such subdivision will be proportionately reduced and
the number of shares of Common Stock obtainable upon exercise of this Warrant
will be proportionately increased. If the Company at any time after the date of
issuance of this Warrant combines (by combination, reverse stock split or
otherwise) one or more classes of its outstanding shares of Common Stock into a
smaller number of shares, any Warrant Exercise Price in effect immediately prior
to such combination will be proportionately increased and the number of shares
of Common Stock obtainable upon exercise of this Warrant will be proportionately
decreased. Any adjustment under this Section 8(d) shall become effective at the
close of business on the date the subdivision or combination becomes effective.


          (e)  Adjustment of Warrant Exercise Price for Registration Statement
               ---------------------------------------------------------------
Failures. If (A) the registration statement (the "Registration Statement")
- --------
covering the resale of the Warrant Shares required to be filed by the Company
pursuant to the Registration Rights Agreement is not filed with the SEC by the
applicable Filing Deadline (as defined in the Registration Rights Agreement) or
declared effective by the SEC on or before the applicable Effectiveness Deadline
(as defined in the Registration Rights Agreement) or (B) after the Registration
Statement has been declared effective by the SEC, sales cannot be made pursuant
to the Registration Statement (whether because of a failure to keep the
Registration Statement effective, to disclose such information as is necessary
for sales to be made pursuant to the Registration Statement, to register
sufficient shares of Common Stock or otherwise), then, as partial relief for the
damages to the holder of this Warrant by reason of any of the foregoing events
(which remedy shall not be exclusive of any other remedies available at law or
in equity), the Warrant Exercise Price in effect at such time shall be reduced
by an amount equal to the product of (I) the Warrant Exercise Price in effect as
of the date of this Warrant (subject to adjustment for stock splits, stock
dividends and other similar transactions) and (II) the sum of (A) 0.01, if the
Registration Statement is not filed with the SEC by the applicable Filing
Deadline, plus (B) 0.01, if the Registration Statement is not effective by the
applicable Effectiveness Deadline, plus (C) the product of .0005 and the sum of
(w) the number of days after the applicable Filing Deadline that the relevant
Registration Statement has not been filed with the SEC, (x) the number of days
after the applicable Effectiveness Deadline that the Registration Statement has
not been declared effective by the SEC, and (y) the number of days that sales
cannot be made pursuant to the Registration Statement in accordance with the
Registration Rights Agreement after the Registration Statement has been declared
effective.

          (f)  Adjustment of Warrant Exercise Price for Company's Failure to
               -------------------------------------------------------------
Timely Exercise.  If the Company shall fail for any reason or for no reason to
- ---------------
issue to the holder within five (5) Business Days of receipt of the Exercise
Delivery Documents (a "Share Delivery Date"), a certificate for the number of
shares of Common Stock to which the holder is entitled or to credit the holder's
balance account with The Depository Trust Company for such number of shares of
Common Stock to which the holder is entitled upon the holder's exercise of this
Warrant or a new Warrant for the number of shares of Common Stock to which such
holder is entitled pursuant to Section 2(b) hereof (A "Warrant Delivery Date"),
then, in addition to any other remedies under this Warrant or the Securities
Purchase Agreement or otherwise available to such holder, including any
indemnification under Section 8 of the Securities Purchase Agreement, the
Warrant Exercise Price in effect at such time shall be reduced by product of (I)
the Warrant Exercise Price in effect as of the date of this Warrant (subject to
adjustment for stock splits, stock dividends and other similar transactions) and
(II) the product of (A) 0.05 and the (B) the sum of (I) the number of days after
the Share Delivery Date that such Exercise is not timely effected and (II) the
number of days after the Warrant Delivery Date such new Warrant is not
delivered.

          (g)  Distribution of Assets. If the Company shall declare or make any
               ----------------------
dividend or other distribution of its assets (or rights to acquire its assets)
to holders of Common Stock, by way of return of capital or otherwise (including,
without limitation, any distribution of cash, stock or other securities,
property or options by way of a dividend, spin off, reclassification, corporate
rearrangement or other similar transaction) ("Distribution"), at any time after
the issuance of this Warrant, then, in each such case:

               (i)    any Warrant Exercise Price in effect immediately prior to
the close of business on the record date fixed for the determination of holders
of Common Stock entitled to receive the Distribution shall be reduced, effective
as of the close of business on such record date, to a price determined by
multiplying such Warrant Exercise Price by a fraction of which (A) the numerator
shall be the Closing Sale Price of the Common Stock on the trading day
immediately preceding such record date minus the value of the Distribution (as
determined in good faith by the Company's Board of Directors) applicable to one
share of Common Stock, and (B) the denominator shall be the Closing Sale Price
of the Common Stock on the trading day immediately preceding such record date;
and

                                     -13-
<PAGE>

               (ii)   either (A) the number of Warrant Shares obtainable upon
exercise of this Warrant shall be increased to a number of shares equal to a
number of shares of Common Stock obtainable immediately prior to the close
business on the record date fixed for the determination of holders of Common
Stock entitled to receive the Distribution multiplied by the reciprocal of the
fraction set forth in the immediately preceeding clause (i), or (B) in the event
that the Distibution is of common stock of a company whose common stock is
traded on a national securities exchange or a national automated quotation
system, then the holder of this Warrant shall receive an additional warrant to
purchase Common Stock, the terms of which shall be identical to those of this
Warrant, except that such warrant shall be exercisable into the amount of the
assets that would have been payable to the holder of this Warrant pursuant to
the Distribution had the holder exercised this Warrant immediately prior to such
record date and with an exercise price equal to the amount by which the exercise
price of this Warrant was decreased with respect to the Distribution pursuant to
the terms of the immediately preceding clause (i).

          (h)  Certain Events. If any event occurs of the type contemplated by
the provisions of this Section 8 but not expressly provided for by such
provisions (including, without limitation, the granting of stock appreciation
rights, phantom stock rights or other rights with equity features), then the
Company's Board of Directors will make an appropriate adjustment in the Warrant
Exercise Price and the number of shares of Common Stock obtainable upon exercise
of this Warrant so as to protect the rights of the holders of the Note Warrants;
provided that no such adjustment will increase the Warrant Exercise Price or
decrease the number of shares of Common Stock obtainable as otherwise determined
pursuant to this Section 8.

          (i)  Notices.
               -------

               (i)    Immediately upon any adjustment of a Warrant Exercise
Price, the Company will give written notice thereof to the holder of this
Warrant, setting forth in reasonable detail, and certifying, the calculation of
such adjustment.

               (ii)   The Company will give written notice to the holder of this
Warrant at least ten (10) days prior to the date on which the Company closes its
books or takes a record (A) with respect to any dividend or distribution upon
the Common Stock, (B) with respect to any pro rata subscription offer to holders
of Common Stock or (C) for determining rights to vote with respect to any
Organic Change (as defined below), dissolution or liquidation, provided that
such information shall be made known to the public prior to or in conjunction
with such notice being provided to such holder.

               (iii)  The Company will also give written notice to the holder of
this Warrant at least ten (10) days prior to the date on which any Organic
Change, dissolution or liquidation will take place, provided that such
information shall be made known to the public prior to or in conjunction with
such notice being provided to such holder.

     Section 9.  Purchase Rights; Reorganization, Reclassification,
                 --------------------------------------------------
Consolidation, Merger or Sale.  (a)  In addition to any adjustments pursuant to
- -----------------------------
Section 8 above, if at any time the

                                     -14-
<PAGE>

Company grants, issues or sells any Options, Convertible Securities or rights to
purchase stock, warrants, securities or other property pro rata to the record
holders of any class of Common Stock (the "Purchase Rights"), then the holder of
this Warrant will be entitled to acquire, upon the terms applicable to such
Purchase Rights, the aggregate Purchase Rights which such holder could have
acquired if such holder had held the number of shares of Common Stock acquirable
upon complete exercise of this Warrant immediately before the date on which a
record is taken for the grant, issuance or sale of such Purchase Rights, or, if
no such record is taken, the date as of which the record holders of Common Stock
are to be determined for the grant, issue or sale of such Purchase Rights.

          (b)     Any recapitalization, reorganization, reclassification,
consolidation, merger, sale of all or substantially all of the Company's assets
to another Person or other transaction in each case which is effected in such a
way that holders of Common Stock are entitled to receive (either directly or
upon subsequent liquidation) stock, securities or assets with respect to or in
exchange for Common Stock is referred to herein as "Organic Change."  Prior to
the consummation of any (i) sale of all or substantially all of the Company's
assets to an acquiring Person or (ii) other Organic Change following which the
Company is not a surviving entity, the Company will secure from the Person
purchasing such assets or the successor resulting from such Organic Change (in
each case, the "Acquiring Entity") written agreement (in form and substance
reasonably satisfactory to the holders of Note Warrants representing a majority
of the shares of Common Stock obtainable upon exercise of the Note Warrants then
outstanding) to deliver to each holder of Note Warrants in exchange for such
Warrants, a security of the Acquiring Entity evidenced by a written instrument
substantially similar in form and substance to this Warrant and reasonably
satisfactory to the holders of the Note Warrants (including, an adjusted warrant
exercise price equal to the value for the Common Stock reflected by the terms of
such consolidation, merger or sale, and exercisable for a corresponding number
of shares of Common Stock acquirable and receivable upon exercise of the Note
Warrants, if the value so reflected is less than any Warrant Exercise Price in
effect immediately prior to such consolidation, merger or sale).  Prior to the
consummation of any other Organic Change, the Company shall make appropriate
provision (in form and substance reasonably satisfactory to the holders of Note
Warrants representing a majority of the shares of Common Stock obtainable upon
exercise of the Note Warrants then outstanding) to insure that each of the
holders of the Note Warrants will thereafter have the right to acquire and
receive in lieu of or in addition to (as the case may be) the shares of Common
Stock immediately theretofore acquirable and receivable upon the exercise of
such holder's Note Warrants, such shares of stock, securities or assets that
would have been issued or payable in such Organic Change with respect to or in
exchange  for the number of shares of Common Stock which would have been
acquirable and receivable upon the exercise of such holder's Warrant as of the
date of such Organic Change (without taking into account any limitations or
restrictions on the exerciseability of this Warrant).

     Section 10.  Lost, Stolen, Mutilated or Destroyed Warrant.  If this Warrant
                  --------------------------------------------
is lost, stolen, mutilated or destroyed, the Company shall, on receipt of an
indemnification undertaking (or, in the case of a mutilated Warrant, the
Warrant), issue a new Warrant of like denomination and tenor as this Warrant so
lost, stolen, mutilated or destroyed.

                                     -15-
<PAGE>

     Section 11.  Notice.  Any notices, consents, waivers or other
                  ------
communications required or permitted to be given under the terms of this Warrant
must be in writing and will be deemed to have been delivered:  (i) upon receipt,
when delivered personally; (ii) upon receipt, when sent by facsimile (provided
confirmation of transmission is mechanically  or electronically generated and

                                    WARRANT

       To Purchase One Hundred Thousand (100,000) Shares of Common Stock
                         (subject to adjustment herein)

                          Expiring September 17, 2009

     THIS IS TO CERTIFY THAT, for value received, Michael A. Waters, or his
respective registered assigns is entitled to purchase from Blue Rhino
Corporation, a Delaware corporation (the "Corporation"), at any time and from
time to time after 9:00 A.M., Winston-Salem, North Carolina time, on September

September 17, 2009 (the "Exercise Period"), at the principal office of the
Corporation which is currently 104 Cambridge Plaza Drive, Winston-Salem, North
Carolina 27104 (or such other address as the Corporation shall specify by notice
to the registered holder of this Warrant) at the Exercise Price, the number of
shares of Common Stock, with a par value of $0.001 per share (the "Common
Stock"), of the Corporation shown above, all subject to adjustment and upon the
terms and conditions as hereinafter provided, and is entitled also to exercise
the other appurtenant rights, powers and privileges hereinafter described.

     Capitalized terms used in this Warrant are defined in Article V.

                                   ARTICLE I
                              EXERCISE OF WARRANTS

     1.1  Method of Exercise and Payment.
          ------------------------------

          (a) Method of Exercise. To exercise this Warrant in whole or in part,
the registered holder of this Warrant (the "Holder") shall deliver to the
principal office of the Corporation at any time during the Exercise Period (1)
this Warrant, (2) a written notice, in substantially the form of the
subscription notice (the "Subscription Notice") attached hereto, of such
Holder's election to exercise this Warrant, which notice shall specify the
number of shares of Common Stock to be purchased or converted into, as the case
may be, the denominations of the share certificate or certificates desired and
the name or names in which such certificates are to be registered, and (3)
payment to the Corporation of the amount equal to the product of the then
applicable Exercise Price multiplied by the number of shares of Common Stock
then being purchased pursuant to one of the payment methods permitted under
Section 1.1(b) below.

<PAGE>

          (b) Method of Payment. Upon receipt of the Warrant and the
Subscription Notice, the Corporation shall determine whether the shares of
Common Stock to be purchased or converted into, as the case may be, by the
exercise of this Warrant are Registered Shares or Unregistered Shares. If the
Holder elects that this Warrant is exercised for Registered Shares, payment may
only be made by either (1) cash, money order, certified check or bank cashier's
check or (2) wire transfer. If the Holder elects that this Warrant is exercised
for Unregistered Shares, payment may be made by (1) cash, money order, certified
check or bank cashier's check, (2) wire transfer or (3) converting the Warrant,
or any portion thereof, into Common Stock pursuant to Section 1.1(c).

          (c) Payment by Warrant Conversion. Subject to any limitations set
forth in this Warrant, the Holder may exercise the purchase right represented by
this Warrant with respect to a particular number of shares of Common Stock
subject to this Warrant and elect to pay for the Underlying Common Stock by
converting the Warrant, or any portion thereof, into Common Stock by specifying
such election in the Subscription Notice. In such event, the Corporation shall
deliver to the Holder (without payment by the Holder of any Exercise Price or
any cash or other consideration) that number of shares of Common Stock equal to
the quotient obtained by dividing (x) the value of this Warrant (or the
specified portion hereof) on the Exercise Date, which value shall be determined
by subtracting (A) the aggregate Exercise Price of the Underlying Common Stock
immediately prior to the exercise of the Warrant from (B) the aggregate Market
Price of the Underlying Common Stock issuable upon exercise of this Warrant (or
the specified portion hereof) on the Exercise Date, by (y) the Market Price of
one share of Common Stock on the Exercise Date.

          (d) Mechanics. Unless the Corporation elects the Buy Out permitted
under Section 1.5 below, the Corporation shall, as promptly as practicable and
in any event within fifteen (15) days after delivery of a Subscription Notice as
described above, execute and deliver or cause to be executed and delivered, in
accordance with such Subscription Notice, a certificate or certificates
representing the aggregate number of shares of Common Stock specified in said
Subscription Notice. The share certificate or certificates so delivered shall be
in such denominations as may be specified in such Subscription Notice and shall
be issued in the name of the Holder or such other name or names as shall be
designated in such Subscription Notice. Such certificate or certificates shall
be deemed to have been issued (and this Warrant or the portion thereof specified
in the Subscription Notice shall be deemed to have been exercised), and such
Holder or any other Person so designated to be named therein shall be deemed for
all purposes to have become a holder of record of such shares, as of the date
the aforementioned Subscription Notice is received by the Corporation, or
delivery thereof is refused (the "Exercise Date"). If this Warrant shall have
been exercised only in part, the Corporation shall, at the time of delivery of
the certificate or certificates, deliver to the Holder a new Warrant evidencing
the rights to purchase or convert the remaining shares of Common Stock called
for by this Warrant, which new Warrant shall in all other respects be identical
with this Warrant, or, at the request of the Holder, appropriate notation may be
made on this Warrant which shall then be refunded to the Holder. The Corporation
shall pay all expenses, taxes and other charges payable in connection with the
preparation, issuance and delivery of share certificates and new Warrants,
except that, if share certificates or new Warrants shall be registered in a name
or names other than the name of the Holder, funds sufficient to pay all transfer
taxes
                                     - 2 -
<PAGE>

payable as a result of such transfer shall be paid by the Holder at the time of
delivering the aforementioned notice of exercise or promptly upon receipt of a
written request of the Corporation for payment.

     1.2 Shares to Be Fully Paid and Nonassessable. All shares of Common Stock
issued upon the exercise of this Warrant shall be validly issued, fully paid and
nonassessable and free from all preemptive rights of any stockholder, and from
all taxes, liens and charges with respect to the issue thereof (other than
transfer taxes).

     1.3 No Fractional Shares to Be Issued. The Corporation shall not be
required to issue fractions of shares of Common Stock upon exercise of this
Warrant. If any fraction of a share would, but for this Section, be issuable
upon any exercise of this Warrant, in lieu of such fractional share the
Corporation may pay to the Holder, in cash, an amount equal to such fraction of
the Market Price per share of outstanding Common Stock of the Corporation on the
Business Day immediately prior to the date of such exercise.

     1.4 Share Legends. Each certificate for shares of Common Stock issued upon
exercise of this Warrant, unless at the time of exercise such shares are
registered under the Securities Act, shall bear the following legend:

     "This security has not been registered under the Securities Act of 1933 and
     may not be sold or offered for sale unless registered pursuant to such Act
     or unless the holder hereof delivers to Blue Rhino Corporation an opinion
     of counsel reasonably acceptable to Blue Rhino Corporation stating that an
     exemption from such registration is available."

     Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon completion
of a public distribution pursuant to a registration statement under the
Securities Act) shall also bear such legend unless, in the opinion of counsel
selected by the holder of such certificate (who may be an employee of such
holder) and reasonably acceptable to the Corporation, the securities represented
thereby need no longer be subject to restrictions on resale under the Securities
Act.

     1.5  Buy Out. On the Exercise Date or on the day that an Organizational
Change is announced (either such date is referred to herein as the "Buy Out
Date"), the Corporation, in its sole discretion, may elect to Buy Out any or all
of the Holder's interest in the Warrant. "Buy Out" means that the Corporation
shall deliver to the Holder (without payment by the Holder of any Exercise Price
or any cash or other consideration) the value of the Warrant, taking into
account the number of shares of Common Stock that the Corporation desires to Buy
Out.  The value of this Warrant (or the specified portion thereof) on the Buy
Out Date shall be determined by subtracting (x) the Exercise Price on the Buy
Out Date from (y) the Market Price of a share of the Common Stock issuable upon
exercise of this Warrant on the Buy Out Date and multiplying the remainder by
(z) the number of shares that the Corporation desires to Buy Out.

                                     - 3 -
<PAGE>

     1.6 Result of Exercise. On the Exercise Date, the rights of the Holder as a
holder of the Warrant will cease and the Person or Persons in whose name or
names any certificate or certificates for shares of Common Stock are to be
issued upon such exercise will be deemed to have become the holder or holders of
record of the shares of Common Stock represented thereby.

     1.7 Not Close Books Until Exercise. The Corporation will not close its
books against the transfer of this Warrant or shares of Common Stock issued or
issuable upon exercise of this Warrant in any manner which interferes with the
timely exercise of this Warrant.

                                   ARTICLE II
                             TRANSFER, EXCHANGE AND
                             REPLACEMENT OF WARRANT

     2.1 Ownership of Warrant. The Corporation may deem and treat the Person in
whose name this Warrant is registered as the holder and owner hereof for all
purposes and shall not be affected by any notice to the contrary, until this
Warrant is presented for registration of transfer as provided in this Article
II.

     2.2  Prohibition on Transfer of Warrant.
          ----------------------------------

          (a) Except as specifically provided in this paragraph (b) of this
Section, the Warrants may not be transferred or assigned by the Holder.

          (b) The Holder may transfer some or all of its interests in the
Warrant to the following Persons ("Permitted Assignees"):

               (i)   a trust created by it for estate planning purposes of which
                     it is a trustee;

               (ii)  a family partnership, limited liability company or
                     corporation;

               (iii) a spouse and/or children of the Holder;

               (iv)  if the Holder is a trust, then to its beneficiaries as
                     permitted under the trust instrument; and

               (v)   if the Holder is a limited liability company, to its
                     members as permitted under such limited liability company's
                     operating agreement and pursuant to the laws of its state
                     of formation.

     2.3 Division or Combination of Warrants. Subject to the limitations of
Section 2.2, this Warrant may be divided or combined with other Warrants upon
surrender hereof and of any Warrant or Warrants with which this Warrant is to be
combined to the Corporation, together with a written notice specifying the names
of the Permitted Assignees and denominations in which the new

                                     - 4 -
<PAGE>

Warrant or Warrants are to be issued, signed by the Holder or their respective
duly authorized agents or attorneys. The Corporation shall execute and deliver a
new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or
combined in accordance with such notice.

     2.4 Loss, Theft, Destruction of Warrant Certificates. Upon receipt of
evidence reasonably satisfactory to the Corporation (an affidavit of the
registered holder will be satisfactory) of the loss, theft, destruction or
mutilation of any Warrant and, in the case of any such loss, theft or
destruction upon receipt of indemnity or security reasonably satisfactory to the
Corporation, or, in the case of any such mutilation, upon surrender and
cancellation of such Warrant, the Corporation will (at its expense) make and
deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new
Warrant of like tenor and representing the right to purchase the same aggregate
number of shares of Common Stock.

     2.5 Expenses of Delivery of Warrants. The Holder shall pay all
administrative expenses and taxes payable in connection with the preparation,
issuance and delivery of Warrants and Underlying Common Stock hereunder.

                                  ARTICLE III

     3.1 Adjustments Generally. The Exercise Price and the number of shares of
Common Stock (or other securities or property) issuable upon exercise of this
Warrant shall be subject to adjustment from time to time upon the occurrence of
certain events, as provided in this Article III.

     3.2 Exercise of Warrant. At any time during the Exercise Period, any Holder
of this Warrant may exercise this Warrant to purchase all or any portion of the
number of shares of Common Stock stated on the face of this Warrant.

     3.3 Exercise Price. The "Exercise Price" shall initially be equal to $7.40
per share. In order to prevent dilution of the exercise rights granted to a
Holder, the Exercise Price will be subject to adjustment from time to time
pursuant to Section 3.4 below.

     3.4 Subdivision or Combination of Common Stock. If the Corporation at any
time subdivides (by any stock split, stock dividend, recapitalization or
otherwise) its outstanding shares of Common Stock into a greater number of
shares, the Exercise Price in effect immediately prior to such subdivision will
be proportionately reduced. If the Corporation at any time combines (by reverse
stock split, recapitalization or otherwise) one or more classes of its
outstanding shares of Common Stock into a smaller number of shares, the Exercise
Price in effect immediately prior to such combination will be proportionately
increased.

     3.5 Notices. Immediately upon any adjustment of the Exercise Price, the
Corporation shall give written notice thereof to the Holder specifying the
Exercise Price in effect thereafter with respect to the Holder.

occurred and (2) receipt by the Holder of a notice from the Company indicating
the kind and amount of securities or assets issuable or distributable to holders
of shares of Common Stock with respect to such event, and upon exercise of this
Warrant during such period, the Holder shall have the right to receive in lieu
of each share of the Underlying Common Stock, 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 of the shares of
the Common Stock.

not agree to hold any of the Securities for any minimum or other specific term

and in accordance with the provisions of Section 2(f).

         b.  Accredited Investor Status.  Such Buyer is an "accredited

such Buyer's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of such Buyer set forth herein in order to

                                       5
<PAGE>

fairness or suitability of the investment in the Securities nor have such
authorities passed upon or endorsed the merits of the offering of the
Securities.

         f.  Transfer or Resale.  Such Buyer understands that except as
             ------------------
provided in the Registration Rights Agreement: (i) the Securities have not been

and may not be offered for sale, sold, assigned or transferred unless (A)
subsequently registered thereunder, (B) such Buyer shall have delivered to the
Company an opinion of counsel, in a form reasonably satisfactory to the Company,
to the effect that such Securities to be sold, assigned or transferred may be
sold, assigned or transferred pursuant to an exemption from such registration,
or (C) such Buyer provides the Company with an opinion of counsel reasonably
acceptable to the Company that such Securities can be sold, assigned or
transferred pursuant to Rule 144 promulgated under the 1933 Act (or a successor
rule thereto) ("Rule 144"); provided, however, that the Buyer shall not be
required to provide an opinion of counsel for sales made pursuant to Rule
144(k); (ii) any sale of the Securities made in reliance on Rule 144  may be
made only in accordance with the terms of Rule 144 and further, if Rule 144 is
not applicable, any resale of the Securities under circumstances in which such
Buyer, as a seller (or the person through whom the sale is made on such Buyer's
behalf) may be deemed to be an underwriter (as that term is defined in the 1933
Act) may require compliance with some other exemption under the 1933 Act or the
rules and regulations of the SEC thereunder; and (iii) neither the Company nor
any other person is under any obligation to register such Securities under the

         g.  Legends.  Such Buyer understands that the certificates or other
             -------
instruments representing the Notes and the Warrants and, until such time as the
sale of the Conversion Shares and the Warrant Shares have been registered under
the 1933 Act as contemplated by the Registration Rights Agreement, the stock
certificates representing the Conversion Shares and the Warrant Shares, except
as set forth below, shall bear a restrictive legend in substantially the
following form (and a stop-transfer order may be placed against transfer of such
stock certificates):

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
     SECURITIES LAWS.  THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY
     NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN
     EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES
     ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS, OR AN OPINION
     OF COUNSEL, IN A FORM REASONABLY SATISFACTORY TO THE COMPANY, THAT
     REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR APPLICABLE STATE SECURITIES
     LAWS OR UNLESS SOLD PURSUANT TO RULE 144(K) UNDER SAID ACT. NOTWITHSTANDING
     THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE
     MARGIN ACCOUNT.

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Securities upon which it is
stamped, if (i) such Securities are registered for sale under the 1933 Act, (ii)
in connection with a sale transaction, such holder provides the Company with an
opinion of counsel, in a form reasonably satisfactory to the Company, to the
effect that a public sale, assignment or transfer of such Securities may be made
without registration under the 1933 Act, or (iii) such holder provides the
Company with an opinion of counsel reasonably acceptable to the Company that
such Securities can be sold pursuant to Rule 144; provided, however, that no
opinion of counsel shall be required for sales made pursuant to Rule 144(k).
Such Buyer acknowledges, covenants and agrees to sell the Securities represented
by a certificate(s) from which the legend has been removed, only pursuant to (i)
a registration statement effective under the 1933 Act, or (ii) advice of counsel
that such sale is exempt from registration required by Section 5 of the 1933
Act.

         h.  Authorization; Enforcement.  This Agreement and the Registration
             --------------------------

adopted a shareholder rights plan or similar arrangement relating to
accumulation of beneficial ownership of Common Stock or a change in control of
the Company.

          v.  Year 2000 Compliance. The Company has initiated a review and
              --------------------
assessment of all areas within its and each Subsidiary's business and operations
that could be materially adversely affected by the "Year 2000 Problem" (that is,
the risk that computer applications used by the Company or any of the
Subsidiaries may be unable to recognize and perform properly date-sensitive
functions involving certain dates prior to and any date after December 31,
1999). Based on the foregoing, the Company believes that the computer
applications that are currently material to its or any Subsidiary's business and
operations are reasonably expected to be able to perform properly date-sensitive
functions for all dates before and after January 1, 2000.

          w.  Environmental Laws. The Company and its Subsidiaries (i) are in
              ------------------
compliance in all material respects with any and all applicable foreign,
federal, state and local laws and regulations relating to the protection of
human health and safety, the environment or hazardous or toxic substances or
wastes, pollutants or contaminants ("Environmental Laws"), (ii) have received
all material permits, licenses or other approvals required of them under
applicable Environmental Laws to conduct their respective businesses and (iii)
are in compliance in all material respects with all terms and conditions of any
such permit, license or approval.

          x.  Title. The Company and its Subsidiaries have good and marketable
              -----
title in fee simple to all real property and good and marketable title to all
personal property owned by them which is material to the business of the Company
and its Subsidiaries, in each case free and clear of all liens, encumbrances and
defects except such as are described in Schedule 3(x) or such as do not
                                        -------------
materially affect the value of such property and do not interfere with the use
made and proposed to be made of such property by the Company and any of its
Subsidiaries. Any real property and facilities held under lease by the Company
and any of its Subsidiaries are held by them under valid, subsisting and
enforceable leases with such exceptions as are not material and do not interfere
with the use made and proposed to be made of such property and buildings by the
Company and its Subsidiaries.

          y.  Insurance. The Company and each of its Subsidiaries are insured
              ---------
by insurers of recognized financial responsibility against such losses and risks
and in such amounts

                                       15
<PAGE>

as management of the Company believes to be prudent and customary in the
businesses in which the Company and its Subsidiaries are engaged. Neither the
Company nor any such Subsidiaries has any reason to believe that it will not be
able to renew its existing insurance coverage as and when such coverage expires
or to obtain similar coverage from similar insurers as may be necessary to
continue its business at a cost that would not materially and adversely affect
the condition, financial or otherwise, or the earnings, business or operations
of the Company and its Subsidiaries, taken as a whole.

          z.  No Other Agreements. The Company has not, directly or indirectly,
              -------------------
made any agreements with any Buyer relating to the terms or conditions of the
transactions contemplated by the Transaction Documents except as set forth in
the Transaction Documents.

          aa. Foreign Corrupt Practices. Neither the Company, nor any of its
              -------------------------
Subsidiaries, nor any director, officer, agent, employee or other person acting
on behalf of the Company or any of its Subsidiaries has, in the course of its
actions for, or on behalf of, the Company, used any corporate funds for any
unlawful contribution, gift, entertainment or other unlawful expenses relating
to political activity; made any direct or indirect unlawful payment to any
foreign or domestic government official or employee from corporate funds;
violated or is in violation of any provision of the U.S. Foreign Corrupt
Practices Act of 1977, as amended; or made any unlawful bribe, rebate, payoff,
influence payment, kickback or other unlawful payment to any foreign or domestic
government official or employee.

          bb. No Materially Adverse Contracts. Except as specifically disclosed
              --------------------------------
in the SEC Documents, or as set forth in Schedule 3(bb), neither the Company
                                         --------------
nor any of its Subsidiaries is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation which in the
judgment of the Company's officers has or is expected in the future to have a
Material Adverse Effect.

     4.   COVENANTS.
          ---------

          a.  Best Efforts. Each party shall use its best efforts timely to
              ------------
satisfy each of the conditions to be satisfied by it as provided in Sections 6
and 7 of this Agreement.

          b.  Form D and Blue Sky. The Company agrees to file a Form D with
              -------------------
respect to the Securities as required under Regulation D and to provide a copy
thereof to each Buyer promptly after such filing. The Company shall, on or
before each of the Closing Dates, take such action as the Company shall
reasonably determine is necessary to qualify the Securities for, or obtain
exemption for the Securities for, sale to the Buyers at the each of Closings
pursuant to this Agreement under applicable securities or "Blue Sky" laws of the
states of the United States, and shall provide evidence of any such action so
taken to the Buyers on or prior to each of the Closing Dates. The Company shall
make all filings and reports relating to the offer and sale of the Securities
required under applicable securities or "Blue Sky"laws of the states of the
United States following each of the Closing Dates.

                                       16
<PAGE>

          c.  Reporting Status. Until the earlier of (i) the date which is one
              ----------------

Registration Rights Agreement) may sell all of the Conversion Shares and the
Warrant Shares without restriction pursuant to Rule 144(k) promulgated under the
1933 Act (or successor thereto) and (ii) the date on which (A) the Investors
shall have sold all the Conversion Shares and the Warrant Shares and (B) none of
the Notes or the Warrants is outstanding (the "Reporting Period"), the Company
shall file all reports required to be filed with the SEC pursuant to the 1934
Act, and the Company shall not terminate its status as an issuer required to
file reports under the 1934 Act even if the 1934 Act or the rules and
regulations thereunder would otherwise permit such termination.

          d.  Use of Proceeds. The Company will use the proceeds from the sale
              ---------------
of the Notes for substantially the same purposes and in substantially the same
amounts as indicated in Schedule 4(d).
                        -------------

          e.  Financial Information. The Company agrees to send the following
              ---------------------
to each Investor (as defined in the Registration Rights Agreement) during the
Reporting Period: (i) within two (2) days after the filing thereof with the SEC,
a copy of its Annual Reports on Form 10-K or Form 10-KSB, its Quarterly Reports
on Form 10-Q or Form 10-QSB, any Current Reports on Form 8-K and any
registration statements (other than on Form S-8) or amendments filed pursuant to
the 1933 Act; (ii) on the same day as the release thereof, facsimile copies of
all press releases issued by the Company or any of its Subsidiaries and (iii)
copies of any notices and other information made available or given to the
stockholders of the Company generally, contemporaneously with the making
available or giving thereof to the stockholders; provided, however, that the
Company will have satisfied its obligations under this Section 4(e) if the
information required by this Section 4(e) is filed on and available for
retrieval from EDGAR.

          f.  Reservation of Shares. The Company shall take all action
              ---------------------
necessary to at all times have authorized, and reserved for the purpose of
issuance, no less than the sum of (A) 200% the number of shares of Common Stock
needed to provide for the issuance of the Conversion Shares and (B) 100% the
number of shares of Common Stock needed to provide for the issuance of the
Warrant Shares (without regard to any limitations on conversions or exercise
thereof).

          g.  Right of First Refusal. Subject to the exceptions described below,
              ----------------------
during the period beginning on the date hereof and ending on, and including, the
date which is the later of (A) one year after the Initial Closing Date and (B)
the date on which none of the Notes remains outstanding, the Company and its
Subsidiaries shall not negotiate or contract with any party for any equity
financing (including any debt financing with an equity component) or issue any
equity securities of the Company or any Subsidiary or securities convertible
into or exchangeable for equity securities of the Company or any Subsidiary
(including debt securities with an equity component) in any form ("Future
Offerings"), unless it shall have first delivered to each Buyer or a designee
appointed by such Buyer written notice (the "Future Offering Notice") describing
the proposed Future Offering, including the size, terms and conditions thereof,
and providing each

                                       17
<PAGE>

Buyer an option to purchase up to its Aggregate Percentage (as defined below) of
the securities to be issued in such Future Offering, as of the date of delivery
of the Future Offering Notice (the limitations referred to in this sentence are
collectively referred to as the "Capital Raising Limitations"). For purposes of
this Section 4(g), "Aggregate Percentage" at any time with respect to any Buyer
shall mean the percentage obtained by dividing (i) the aggregate principal
amount of the Notes issued to such Buyer on the Closing Date by (ii) the
aggregate principal amount of the Notes issued to all the Buyers on the Closing
Date. A Buyer can exercise its option to participate in a Future Offering by
delivering written notice thereof to participate to the Company within three (3)
Business Days after receipt of a Future Offering Notice, which notice shall
state the quantity of securities being offered in the Future Offering that such
Buyer will purchase, up to its Aggregate Percentage, and that number of
securities it is willing to purchase in excess of its Aggregate Percentage. In
the event that one or more Buyers fail to elect to purchase up to each such
Buyer's Aggregate Percentage of the Future Offering, then each Buyer which has
indicated that it is willing to purchase a number of securities in such Future
Offering in excess of its Aggregate Percentage shall be entitled to purchase up
to its pro rata portion (determined in the same manner as described in the
preceding sentence) of the securities in the Future Offering which one or more
of the Buyers have not elected to purchase. In the event the Buyers fail to
elect to fully participate in the Future Offering within the periods described
in this Section 4(g), the Company shall have 45 days thereafter to sell the
securities of the Future Offering that the Buyers did not elect to purchase,
upon terms and conditions, no more favorable to the purchasers thereof than
specified in the Future Offering Notice. In the event the Company has not sold
such securities of the Future Offering within such 45 day period, the Company
shall not thereafter issue or sell such securities without first offering such
securities to the Buyers in the manner provided in this Section 4(g). The
Capital Raising Limitations shall not apply to (i) a loan from a commercial bank
which does not have any equity feature, (ii) the Company's issuances of
securities (A) as consideration in a merger or consolidation, (B) in connection
with any strategic partnership or joint venture (the primary purpose of which is
not to raise equity capital) or (C) as consideration for the acquisition of a
business, product, license or other assets by the Company, (iii) the issuance of
Common Stock in a firm commitment, underwritten public offering, (iv) the
issuance of securities upon exercise or conversion of the Company's options,
warrants or other convertible securities outstanding as of the date hereof
provided the terms of such securities are not amended after the date hereof, (v)
the grant of additional options or warrants, or the issuance of additional
securities, under any Company stock option plan, restricted stock plan or stock
purchase plan for the benefit of the Company's employees, officers, directors
for services provided to the Company, (vi) the issuance of Common Stock at a
discount of between 0% and 20% and not accompanied by the issuance of warrants
or any other right to acquire or receive any additional capital stock of the
Company, (vii) up to 156,704 options issued after the date of this Agreement
pursuant to the Company's "distribution option plan" approved by the board of
directors of the Company, provided such options are not issued to affiliates of
the Company and the exercise price of such options is not less than the market
price of the Common Stock on the date of issuance of such option, or (viii) the
Concurrent Private Placement. The Buyers shall not be required to participate or
exercise their right of first refusal with respect to a particular Future
Offering in order to exercise their right of first refusal with respect to later
Future Offerings.

                                       18

          h.  Listing. The Company shall promptly secure the listing of all of
              -------
the Registrable Securities (as defined in the Registration Rights Agreement)
upon each national securities exchange and automated quotation system (including
the Nasdaq National Market), if any, upon which shares of Common Stock are then
listed (subject to official notice of issuance) and shall maintain, so long as
any other shares of Common Stock shall be so listed, such listing of all
Registrable Securities from time to time issuable under the terms of the
Transaction Documents. The Company shall maintain the Common Stock's
authorization for listing on the Nasdaq National Market or the New York Stock
Exchange ("NYSE"). Neither the Company nor any of its Subsidiaries shall take
any action which may result in the delisting or suspension of the Common Stock
on the Nasdaq National Market or NYSE (other than to switch listings from the
Nasdaq National Market to NYSE). The Company shall promptly, and in no event
later than the following Business Day, offer to provide to such Buyer copies of
any notices it receives from the Nasdaq National Market or NYSE regarding the
continued eligibility of the Common Stock for listing on such automated
quotation system or securities exchange, provided that such notices shall not
contain any material non-public information. The Company shall pay all fees and
expenses in connection with satisfying its obligations under this Section 4(h).

          i.  Expenses. Subject to Section 9(l) below, at the Initial Closing,
              --------
the Company shall reimburse the Buyers for the Buyers' expenses (including legal
expenses, in connection with due diligence and negotiating and preparing the
Transaction Documents and consummating the transactions contemplated thereby) up
to an aggregate of $50,000.

          j.  Transactions With Affiliates. So long as (i) any Notes or Warrants
              ----------------------------
are outstanding or (ii) any Buyer owns Conversion Shares or Warrant Shares with
a market value of $500,000 the Company shall not, and shall cause each of its
Subsidiaries not to, enter into, amend, modify or supplement, or permit any
Subsidiary to enter into, amend, modify or supplement, any agreement,
transaction, commitment or arrangement with any of its or any Subsidiary's
officers, directors, person who were officers or directors at any time during
the previous two years, stockholders who beneficially own 5% or more of the
Common Stock, or affiliates or with any individual related by blood, marriage or
adoption to any such individual or with any entity in which any such entity or
individual owns a 5% or more beneficial interest (each a "Related Party"),
except for (a) customary employment arrangements and benefit programs on
reasonable terms, (b) any agreement, transaction, commitment or arrangement
which is approved by a majority of the disinterested directors of the Company or
(c) any agreement, transaction, commitment or arrangement on an arms-length
basis on terms no less favorable than terms which would have been obtainable
from a person other than such Related Party. For purposes hereof, any director
who is also an officer of the Company or any Subsidiary of the Company shall not
be a disinterested director with respect to any such agreement, transaction,
commitment or arrangement. "Affiliate" for purposes hereof means, with respect
to any person or entity, another person or entity that, directly or indirectly,
(i) has a 5% or more equity interest in that person or entity, (ii) has 5% or
more common ownership with that person or entity, (iii) controls that person or
entity, or (iv) shares common control with that person or entity. "Control" or
"controls" for

                                       19
<PAGE>

purposes hereof means that a person or entity has the power, direct or indirect,
to conduct or govern the policies of another person or entity.

          k.  Proxy Statement. On or before the earlier of (A) the date on which
              ---------------
the Company has its next annual meeting of stockholders or (B) January 31, 2000
(the "Stockholder Meeting Deadline"), a proxy statement, which has been
previously reviewed by the Buyers and a counsel of their choice, soliciting each
such stockholder's affirmative vote at such stockholder meeting for approval of
the Company's issuance of all of the Securities as described in this Agreement
in accordance with applicable law and the rules and regulations of the Nasdaq
National Market, and the Company shall use its best efforts to solicit its
stockholders' approval of such issuance of the Securities and cause the Board of
Directors of the Company to recommend to the stockholders that they approve such
proposal. If the Company fails to hold a meeting of its stockholders by the
Stockholder Meeting Deadline, then, as partial relief (which remedy shall not be
exclusive of any other remedies available at law or in equity), the Company
shall pay to each holder of Notes an amount in cash per $10,000 in principal
amount of the Notes equal to the product of (i) $10,000 multiplied by (ii) .015
multiplied by (iii) the quotient of (x) the number of days after the Stockholder
Meeting Deadline and prior to the date that a meeting of the Company's
stockholders is held, divided by (y) 30. The Company shall make the payments
referred to in the immediately preceding sentence within five days of the
earlier of (I) the holding of the meeting of the Company's stockholders and (II)
the last day of each 30-day period beginning on the Stockholder Meeting
Deadline.

          l.  Filing of Form 8-K. On or before the first Business Day following
              ------------------
each of the Closing Dates and the Additional Note Notice Date, the Company shall
file a Form 8-K with the SEC describing the terms of the transaction
contemplated by the Transaction Documents and consummated at such Closing, in
each case in the form required by the 1934 Act. The Company shall also file a
Form 8-K with the SEC describing the terms of the Concurrent Private Placement
on or before the first Business Day following the closing of such Concurrent
Private Placement and, in any event, prior to or concurrent with the Form 8-K
referred to in the immediately preceding sentence.

          m.  Corporate Existence. So long as any Buyer beneficially owns any
              -------------------
Notes or Warrants, the Company shall maintain its corporate existence and shall
not sell all or substantially all of the Company's assets, except in the event
of a merger or consolidation or sale of all or substantially all of the
Company's assets, where (I) the surviving or successor entity in such
transaction (i) assumes the Company's obligations hereunder and under the
agreements and instruments entered into in connection herewith and (ii) is a
publicly traded corporation whose common stock is listed for trading on the
Nasdaq National Market or NYSE, or (II) the Company has satisfied the
requirements of Sections 4(a) and 4(b) of the Note, to the extent applicable,
including the payment of the Change of Control Redemption Price (as defined in
the Note) upon the Company's receipt of a Notice of Redemption upon Change of
Control.

     5.   TRANSFER AGENT INSTRUCTIONS.
          ---------------------------

          The Company shall issue irrevocable instructions to its transfer
agent, and any subsequent transfer agent, to issue certificates, registered in
the name of each Buyer or its respective nominee(s), for the Conversion Shares
and the Warrant Shares in such amounts as specified from time to time by each
Buyer to the Company upon conversion of the Notes or exercise of the Warrants
(in the form attached hereto as Exhibit E, the "Irrevocable Transfer Agent
                                ---------
Instructions"). Prior to registration of the Conversion Shares and the Warrant
Shares under the 1933 Act, all such certificates shall bear the restrictive
legend specified in Section 2(g) of this Agreement. The Company warrants that no
instruction other than the Irrevocable Transfer Agent Instructions referred to
in this Section 5, and stop transfer instructions to give effect to Section 2(f)
hereof (in the case of the Conversion Shares and the Warrant Shares, prior to
registration of the Conversion Shares and the Warrant Shares under the 1933 Act)
will be given by the Company to its transfer agent with respect to the
Securities and that the Securities shall otherwise be freely transferable on the
books and records of the Company as and to the extent provided in this Agreement
and the Registration Rights Agreement. Nothing in this Section 5 shall affect in
any way each Buyer's obligations and agreements set forth in Section 2(g) to
comply with all applicable prospectus delivery requirements, if any, upon resale
of the Securities. If a Buyer provides the Company with an opinion of counsel,
in a form reasonable satisfactory to the Company, that registration of a resale
by such Buyer of any of such Securities is not required under the 1933 Act or
such Buyer provides the Company with an opinion of counsel reasonably acceptable
to the Company that the Securities can be sold pursuant to Rule 144 (provided,
however, that the Buyer will not be required to give an opinion of counsel for
sales made pursuant to Rule 144(k)), the Company shall permit the transfer, and,
in the case of the Conversion Shares and the Warrant Shares, promptly instruct
its transfer agent to issue one or more certificates in such name and in such
denominations as specified by such Buyer and without any restrictive legends.
The Company acknowledges that a breach by it of its obligations hereunder will
cause irreparable harm to the Buyers by vitiating the intent and purpose of the
transaction contemplated hereby. Accordingly, the Company acknowledges that the
remedy at law for a breach of its obligations under this Section 5 will be
inadequate and agrees, in the event of a breach or threatened breach by the
Company of the provisions of this Section 5, that the Buyers shall be entitled,
in addition to all other available remedies, to an injunction restraining any
breach and requiring immediate issuance and transfer, without the necessity of
showing economic loss and without any bond or other security being required.

the State of Delaware shall govern all issues concerning the relative rights of
the Company and its stockholders.  All other questions concerning the
construction, validity, enforcement and interpretation of this Agreement shall
be governed by the internal laws of the State of New York, without giving effect
to any choice of law or conflict of law provision or rule (whether of the State
of New York or any other jurisdictions) that would cause the application of the
laws of any jurisdictions other than the State of New York.  Each party hereby
irrevocably submits to the non-exclusive jurisdiction of the state and federal
courts sitting the City of New York, borough of Manhattan for the adjudication
of any dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and
agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of any such court, that such suit, action
or proceeding is brought in an inconvenient forum or that the venue of such
suit, action or proceeding is improper.  Each party hereby irrevocably waives
personal service of process and consents to process being served in any such
suit, action or proceeding by mailing a copy thereof to such party at the
address for such notices to it under this Agreement and agrees that such service
shall constitute good and sufficient service of process and notice thereof.
Nothing contained herein shall be deemed to limit in any way any right to serve
process in any manner permitted by law.  EACH PARTY HEREBY IRREVOCABLY WAIVES
ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE
ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT
OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

         b.  Counterparts.  This Agreement may be executed in two or more
             ------------
identical counterparts, all of which shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each
party and delivered to the other party; provided that a facsimile signature
shall be considered due execution and shall be binding upon

                                       27
<PAGE>

the signatory thereto with the same force and effect as if the signature were an
original, not a facsimile signature.

         c.  Headings.  The headings of this Agreement are for convenience of
             --------
reference and shall not form part of, or affect the interpretation of, this
Agreement.

         d.  Severability.  If any provision of this Agreement shall be invalid
             ------------
or unenforceable in any jurisdiction, such invalidity or unenforceability shall
not affect the validity or enforceability of the remainder of this Agreement in
that jurisdiction or the validity or enforceability of any provision of this
Agreement in any other jurisdiction.

herein or therein, neither the Company nor any Buyer makes any representation,
warranty, covenant or undertaking with respect to such matters.  No provision of

aggregate principal amount of the Initial Notes on the Initial Closing Date or,
if prior to the Initial Closing Date, the Buyers listed on the Schedule of
Buyers as being obligated to purchase at least two-thirds (2/3) of the aggregate
principal amount of the Notes proposed to be issued at the Initial Closing.  No
provision hereof may be waived other than by an instrument in writing signed by
the party against whom enforcement is sought.  No such amendment shall be
effective to the extent that it applies to less than all of the holders of the
Notes or Warrants then outstanding.  No consideration shall be offered or paid
to any person to amend or consent to a waiver or modification of any provision
of any of the Transaction Documents unless the same consideration also is
offered to all of the parties to the Transaction Documents or holders of the
Notes as the case may be.

security), to recover damages by reason of any breach of any provision of this
Agreement and to exercise all other rights granted by law.

         p.  Payment Set Aside.  To the extent that the Company makes a payment
             -----------------
or payments to any Buyer hereunder or pursuant to the Registration Rights
Agreement or the Warrants or such Buyer enforces or exercises its rights
hereunder or thereunder, and such payment or payments or the proceeds of such
enforcement or exercise or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside, recovered from, disgorged
by or are required to be refunded, repaid or otherwise restored to the Company,
a trustee, receiver or any other person under any law (including, without
limitation, any bankruptcy law, state or federal law, common law or equitable
cause of action), then to the extent of any such restoration the obligation or
part thereof originally intended to be satisfied shall be revived and continued
in full force and effect as if such payment had not been made or such
enforcement or setoff had not occurred.

Date] (the "Maturity Date"), and to pay interest ("Interest") on the unpaid
principal balance hereof at the rate of 5.0% per annum from the date hereof (the
"Issuance Date") until the same becomes due and payable, whether at maturity or
upon acceleration or by conversion or redemption in accordance with the terms
hereof or otherwise.  Interest on this Note shall commence accruing on the
Issuance Date and shall be computed on the basis of a 365-day year and actual
days elapsed and shall be payable at the time of optional or mandatory
conversion or redemption of the principal to which such interest relates in
accordance with Section 1 hereof.  Any amount of interest on this Note which is
not paid when due shall bear interest at the rate of 18% per annum from the date
thereof until the same is paid ("Default Interest").

available funds to such account as the Holder may from time to time designate by
written notice in accordance with the provisions of this Note.  Whenever any

not a Business Day (as defined below), the same shall instead be due on the next
succeeding day which is a Business Day and, in the case of any interest payment
date which is not the date on which this Note is paid in full, the extension of
the due date thereof shall not be taken into account for purposes of determining
the amount of interest due on such date.  For purposes of this Note, "Business
Day" shall mean any day other than a Saturday, Sunday or a day on which
commercial banks in The City of New York are authorized or required by law or

Purchase Agreement").  This Note and the Other Notes issued by the Company
pursuant to the Securities Purchase Agreement are collectively referred to in

          bases, the Closing Bid Price of such security on such date shall be
          the fair market value as mutually determined by the Company and the
          Holders of the Notes.  If the Company and the Holders of the Notes are
          unable to agree upon the fair market value of the Common Stock, then
          such dispute shall be resolved pursuant to Section 2(e)(iii) below

          securities exchange or trading market for such security, the dollar
          volume-weighted average price of such security on the principal
          securities exchange or trading market where such security is listed or

          function), or if the foregoing do not apply, the dollar volume-
          weighted average price of such security in the over-the-counter market

          security on such date shall be the fair market value as mutually
          determined by the Company and the Holders of the Notes.  If the

          (c)  Conversion.
               ----------

               (i)  Conversion Rate. The number of shares of Common Stock
                    ---------------
     issuable upon conversion of a Conversion Amount of this Note pursuant to
     Section 2(b) shall be determined according to the following formula (the

                              Conversion Amount
                              -----------------
                              Conversion Price

               (ii) Cash Payment of Additional Amount. Subject to the notice
                    ---------------------------------
     provisions of this Section 2(c)(ii), upon conversion pursuant to Sections
     2(b) or 2(e)(vii), the Company shall have the right to elect to pay the
     Additional Amount in cash, in lieu of conversion to Common Stock. If the

     paid simultaneously with the delivery to the Holder of the certificates
     representing the Common Stock issuable upon conversion in accordance with
     Section 2(e)(ii). In order to exercise its right to pay any Additional
     Amount in cash, the Company must advise each Holder of the Notes in writing
     (the "Cash Payment Notice") that the Additional Amount shall be paid in
     cash until such time as the Company shall terminate the Cash Payment Notice

     deemed to have been delivered pursuant to Section 25. The Termination
     Notice shall be effective on the fifth Business Day after the date the
     Termination Notice is deemed to have been delivered pursuant to Section 25
     unless a later date shall be specified in the Termination Notice.

          (d)  Limitations on Beneficial Ownership. The Company shall not effect
               -----------------------------------
     any conversion of this Note and no Holder shall have the right to convert
     any portion of this Note pursuant to Section 2(b) to the extent that after
     giving effect to such conversion such Person (together with such Person's
     affiliates) would beneficially own in excess of 4.99% of the outstanding
     shares of the Common Stock following such conversion. For purposes of the
     foregoing sentence, the number of shares of Common Stock beneficially owned
     by a Person and its affiliates shall include the number of shares of Common
     Stock issuable upon conversion of this Note with respect to which the
     determination of such sentence is being made, but shall exclude the number
     of shares of Common Stock which would be issuable upon (i) conversion of
     the remaining, nonconverted portion of this Note beneficially owned by such
     Person and its affiliates and (ii) exercise or conversion of the
     unexercised or unconverted portion of any other securities of the Company
     (including, without limitation, any warrants) subject to a limitation on
     conversion or exercise analogous to the limitation contained herein
     beneficially owned by such Person and its affiliates. Except as set forth
     in the preceding sentence, for purposes of this Section 2(d), beneficial
     ownership shall be calculated in accordance with Section 13(d) of the
     Securities Exchange Act of 1934, as amended. For purposes of this Section
     2(d), in determining the number of outstanding shares Common Stock a Holder
     may rely on the number of outstanding shares of Common Stock as reflected
     in (1) the Company's most recent Form

                                      -5-
<PAGE>

     10-Q or Form 10-K, as the case may be, (2) a more recent public
     announcement by the Company or (3) any other notice by the Company or its
     transfer agent setting forth the number of shares of Common Stock
     outstanding. For any reason at any time, upon the written or oral request
     of the Holder, the Company shall immediately confirm orally and in writing
     to the Holder the number of shares Common Stock then outstanding. In any
     case, the number of outstanding shares of Common Stock shall be determined
     after giving effect to exercises of Warrants (as defined in the Securities
     Purchase Agreement) and conversions of the Notes by the Holder and its
     affiliates since the date as of which such number of outstanding shares of
     Common Stock was reported.

          (e)  Mechanics of Conversion.  The conversion of this Note shall be
               -----------------------
     conducted in the following manner:

               (i)  Holder's Delivery Requirements.  To convert this Note into
                    ------------------------------
          shares of Common Stock on any date (the "Conversion Date"), the Holder
          hereof shall (A) transmit by facsimile (or otherwise deliver), for
          receipt on or prior to 11:59 p.m., Eastern Time on such date, a copy
          of a fully executed notice of conversion in the form attached hereto
          as Exhibit I (the "Conversion Notice") to the Company with a copy
          thereof to the Company's designated transfer agent (the "Transfer
          Agent") and (B) if required by Section 2(e)(viii), surrender to a
          common carrier for delivery to the Company as soon as practicable
          following such date the original Note being converted (or an
          indemnification undertaking with respect to such Note in the case of
          its loss, theft or destruction).

               (ii) Company's Response.  Upon receipt by the Company of a copy
                    ------------------
          of a Conversion Notice, the Company (1) shall immediately send, via
          facsimile, a confirmation of receipt of such Conversion Notice to such
          Holder and the Transfer Agent,  which confirmation shall constitute an
          instruction to the Transfer Agent to process such Conversion Notice in
          accordance with the terms herein and (2) on or before the second
          Business Day following the date of receipt by the Company of such
          Conversion Notice (the "Share Delivery Date"), (A) issue and deliver
          to the address as specified in the Conversion Notice, a certificate,
          registered in the name of the Holder or its designee, for the number
          of shares of Common Stock to which the Holder shall be entitled, or
          (B) provided the Transfer Agent is participating in The Depository
          Trust Company ("DTC") Fast Automated Securities Transfer Program, upon
          the request of the Holder, credit such aggregate number of shares of
          Common Stock to which the Holder shall be entitled to the Holder's or
          its designee's balance account with DTC through its Deposit Withdrawal
          Agent Commission system.  Subject to Section 2(e)(viii), if less than
          the Conversion Amount of this Note is submitted for conversion, then
          the Company shall, as soon as practicable and in no event later than
          three Business Days after receipt of the Note (the "Note Delivery
          Date") and at its own expense, issue and deliver to the Holder a new
          Note for the outstanding principal amount not converted.

                                      -6-

               (iii) Dispute Resolution.  In the case of a dispute as to the
                     ------------------
          determination of the Market Price or the arithmetic calculation of the
          Conversion Rate, the Company shall instruct the Transfer Agent to
          issue to the Holder the number of shares of Common Stock that is not
          disputed and shall submit the disputed determinations or arithmetic
          calculations to the Holder via facsimile within one (1) Business Day
          of receipt of such Holder's Conversion Notice.  If such Holder and the
          Company are unable to agree upon the determination of the Market Price
          or arithmetic calculation of the Conversion Rate within one (1)
          Business Day of such disputed determination or arithmetic calculation
          being submitted to the Holder, then the Company shall within one (1)
          Business Day submit via facsimile (A) the disputed determination of
          the Market Price to an independent, reputable investment bank selected
          by the Company and approved by the Holders of the Notes representing a
          majority of the Conversion Amounts of the Notes then outstanding or
          (B) the disputed arithmetic calculation of the Conversion Rate to the
          Company's independent, outside accountant.  The Company shall cause
          the investment bank or the accountant, as the case may be, to perform
          the determinations or calculations and notify the Company and the
          Holders of the results no later than forty-eight (48) hours from the
          time it receives the disputed determinations or calculations.  Such
          investment bank's or accountant's determination or calculation, as the
          case may be, shall be binding upon all parties absent manifest error.

               (iv)  Record Holder.  The person or persons entitled to receive
                     -------------
          the shares of Common Stock issuable upon a conversion of this Note
          shall be treated for all purposes as the record Holder or Holders of
          such shares of Common Stock as of the close of business on the
          Conversion Date.

               (v)   Company's Failure to Timely Convert.
                     -----------------------------------

                                      -7-
<PAGE>


                    (A)  Void Conversion Notice; Adjustment to Conversion Price.
                         ------------------------------------------------------
               If for any reason the Holder has not received all of the shares
               of Common Stock prior to the tenth (10th) Business Day after the
               expiration of the Share Delivery Date with respect to a
               conversion of this Note, then the Holder, upon written notice to
               the Company, may void its Conversion Notice with respect to, and
               retain or have returned, as the case may be, any principal amount
               of this Note that has not been converted pursuant to such
               Holder's Conversion Notice; provided that the voiding of a
                                           --------
               Holder's Conversion Notice shall not effect the Company's
               obligations to make any payments which have accrued prior to the
               date of such notice pursuant to Section 2(e)(v)(A) or otherwise.
               Thereafter, the Fixed Conversion Price of the principal amount of
               this Note returned or retained by the Holder for failure to
               timely convert shall be adjusted to the lesser of (I) the Fixed
               Conversion Price as in effect on the date on which the Holder
               voided the Conversion Notice and (II) the lowest Closing Bid
               Price during the period beginning on the Conversion Date and
               ending on the date such Holder voided the Conversion Notice,
               subject to further adjustment as provided in this Note.

                    (B)  Redemption.  If for any reason the Holder has not
                         ----------
               received all of the shares of Common Stock prior to the tenth
               (10th) Business Day after  the Share Delivery Date with respect
               to a conversion of this Note (a "Conversion Failure"), then the
               Holder, upon written notice to the Company, may require that the
               Company redeem all of the Conversion Amount of this Note,
               including the Conversion Amount previously submitted for
               conversion and with respect to which the Company has not
               delivered shares of Common Stock, in accordance with Section 3.

                                      -8-
<PAGE>

               (vi)   Pro Rata Conversion and Redemption.  In the event the
                      ----------------------------------
          Company receives a Conversion Notice from more than one Holder of the
          Notes for the same Conversion Date and the Company can convert some,
          but not all, of the Notes submitted for conversion, the Company shall
          convert from each Holder electing to have Notes converted at such time
          a pro rata amount of such Holder's Conversion Amount submitted for
          conversion based on the principal amount of the Notes submitted for
          conversion on such date by such Holder relative to the Conversion
          Amount of all Notes submitted for conversion on such date.

               (vii)  Mandatory Conversion or Redemption at Maturity.  If any
                      ----------------------------------------------
          Conversion Amount of this Note remains outstanding on the Maturity
          Date, then all of Conversion Amount, at the  Company's option, either
          (i) shall be converted at the Conversion Price for the Common Stock as
          of such date as if the Holder  had given the Conversion Notice on the
          Maturity Date (a "Maturity Date Mandatory Conversion"), or (ii) shall
          be redeemed as of such date (a "Maturity Date Mandatory Redemption")
          for an amount in cash equal to the Conversion Amount on the Maturity
          Date (the "Maturity Date Redemption Price"). The Company shall be
          deemed to have elected a Maturity Date Mandatory Redemption unless it
          delivers written notice to the Holder at least 20 Business Days prior
          to the Maturity Date of its election to effect a Maturity Date
          Mandatory Conversion.  If the Company elects a Maturity Date Mandatory
          Redemption, then on the Maturity Date the Company shall pay to each
          the Holder outstanding on the Maturity Date, by wire transfer of
          immediately available funds, an amount equal to the Maturity Date
          Redemption Price.  If the Company elects a Maturity Date Mandatory
          Redemption and shall fail to redeem all of the Conversion Amount of
          this Note outstanding on the Maturity Date by payment of the Maturity
          Date Redemption Price, then in addition to any remedy the Holder may
          have under this Note, the Securities Purchase Agreement and the
          Registration Rights Agreement, the Holder shall have the option to
          require the Company to convert any or all of the Conversion Amount
          that the Company elected to redeem under this Section 2(e)(vii) and
          for which the Maturity Date Redemption Price (together with any
          interest thereon) has not been paid into the number of shares of
          Common Stock the Holder would have received if the Holder had given a
          Conversion Notice for such Conversion Amount on the Maturity Date.

               (viii) Book-Entry.  Notwithstanding anything to the contrary set
                      ----------
          forth herein, upon conversion of any portion of this Note in
          accordance with the terms hereof, the Holder thereof shall not be
          required to physically surrender this Note to the Company unless the
          full Conversion Amount represented by this Note is being converted.
          The Holder and the Company shall maintain records showing the
          Conversion Amount so converted and the dates of such conversions or
          shall use such other method, reasonably satisfactory to the Holder and
          the Company, so as not to require physical surrender of this Note upon
          each such conversion.  In the event of any dispute or discrepancy,
          such records of the Company shall be controlling and determinative in
          the absence of manifest error.  Notwithstanding

                                      -9-
<PAGE>

          the foregoing, if this Note is converted as aforesaid, the Holder may
          not transfer this Note unless the Holder first physically surrenders
          this Note to the Company, whereupon the Company will forthwith issue
          and deliver upon the order of the Holder a new Note of like tenor,
          registered as the Holder may request, representing in the aggregate
          the remaining Conversion Amount represented by this Note. The Holder
          and any assignee, by acceptance of a this Note or such new Note,
          acknowledge and agree that, by reason of the provisions of this
          paragraph, following conversion of any portion of this Note, the
          Conversion Amount (including the principal of this Note) represented
          by this Note may be less than the principal amount and the accrued
          interest set forth on the face hereof.

          (f)  Taxes.  The Company shall pay any and all taxes that may be
               -----
     payable with respect to the issuance and delivery of Common Stock upon the
     conversion of Notes.

          (g)  Adjustments to Conversion Price -- Dilution and Other Events.  In
               ------------------------------------------------------------
     addition to any other adjustments provided herein, the Conversion Price
     will be subject to adjustment from time to time as provided in this Section
     2(g).

               (i)  Adjustment of Fixed Conversion Price upon Subdivision or
                    --------------------------------------------------------
          Combination of Common Stock.  If the Company at any time subdivides
          ---------------------------
          (by any stock split, stock dividend, recapitalization or otherwise)
          one or more classes of its outstanding shares of Common Stock into a
          greater number of shares, the Fixed Conversion Price in effect
          immediately prior to such subdivision will be proportionately reduced.
          If the Company at any time combines (by combination, reverse stock
          split or otherwise) one or more classes of its outstanding shares of
          Common Stock into a smaller number of shares, the Fixed Conversion
          Price in effect immediately prior to such combination will be
          proportionately increased.

               (ii) Holder's Right of Alternative Variable Conversion Price
                    -------------------------------------------------------
          Following Issuance of Convertible Securities.  If the Company in any
          --------------------------------------------
          manner issues or sells Convertible Securities or Options that are
          convertible into or exchangeable for Common Stock at a price which
          varies or may vary with the market price of the Common Stock,
          including by way of periodic resets to a fixed price (each of the
          formulations for such variable price being herein referred to as, a
          "Variable Price"), and such Variable Price is not calculated using the
          same formula used to calculate the Daily Market Price in effect
          immediately prior to the time of  such issue or sale, the Company
          shall provide written notice thereof via facsimile and overnight
          courier to each Holder of the Notes ("Variable Notice") on the date of
          issuance of such Convertible Securities or Options.  From and after
          the date the Company issues any such Convertible Securities with a
          Variable Price, the Holder shall have the right, but not the
          obligation, in its sole discretion to substitute a Variable Price for
          the Daily Market Price upon conversion of any part of the Notes by
          designating in the Conversion Notice delivered upon conversion of such
          Notes that solely for purposes of such conversion the Holder is
          relying on a Variable Price rather than the Daily Market Price then in
          effect.  The Holder's election to

                                      -10-
<PAGE>

          rely on a Variable Price for a particular conversion of Notes shall
          not obligate the Holder to rely on a Variable Price for any future
          conversions of Notes.

               (iii)  Adjustment of Conversion Price for Registration Statement
          Failures. If (A) the registration statement (the "Registration
          Statement") covering the resale of the shares of Common Stock issuable
          upon conversion of the Notes required to be filed by the Company
          pursuant to the Registration Rights Agreement is not filed with the
          SEC by the applicable Filing Deadline (as defined in the Registration
          Rights Agreement) or declared effective by the SEC on or before the
          applicable Effectiveness Deadline (as defined in the Registration
          Rights Agreement) or (B) after the Registration Statement has been
          declared effective by the SEC, sales cannot be made pursuant to the
          Registration Statement (whether because of a failure to keep the
          Registration Statement effective, to disclose such information as is
          necessary for sales to be made pursuant to the Registration Statement,
          to register sufficient shares of Common Stock or otherwise), then, as
          partial relief for the damages to the Holder of this Note by reason of
          any of the foregoing events (which remedy shall not be exclusive of
          any other remedies available at law or in equity), the Conversion
          Percentage in effect at such time shall be reduced by a number of
          percentage points equal to the sum of (A) 1.0, if the Registration
          Statement is not filed with the SEC by the applicable Filing Deadline,
          plus (B) 1.0, if the Registration Statement is not effective by the
          applicable Effectiveness Deadline, plus (C) the product of .05 and the
          sum of (w) the number of days after the Filing Deadline that the
          relevant Registration Statement has not been filed with the SEC, (x)
          the number of days after the applicable Effectiveness Deadline that
          the Registration Statement has not been declared effective by the SEC,
          and (y) the number of days that sales cannot be made pursuant to the
          Registration Statement in accordance with the Registration Rights
          Agreement after the Registration Statement has been declared
          effective.

               (iv) Adjustment of Conversion Price for Company's Failure to
          Timely Convert. If within five (5) Business Days after the Company's
          receipt of a facsimile or other copy of the Conversion Notice the
          Company shall fail to issue a certificate to the Holder or credit the
          Holder's balance account with DTC for the number of shares of Common
          Stock to which such Holder is entitled upon such Holder's conversion
          of this Note or, subject to Section 2(e)(viii), the Company shall fail
          to issue a new Note representing the principal amount to which such
          Holder is entitled, if any, pursuant to Section 2(e)(ii), in addition
          to all other available remedies which such Holder may pursue hereunder
          and under the Securities Purchase Agreement (including indemnification
          pursuant to Section 8 thereof), the Conversion Percentage in effect at
          such time and applying to the Conversion Amount of the Note for which
          shares of Common Stock have failed to be delivered and/or for which a
          new Note has not been delivered shall be reduced by a number of
          percentage points equal to the product of (A) 0.5 and (B) the sum of
          (I) the number of days after the Share Delivery Date such conversion
          is not timely effected and (II) the number of days after the Note
          Delivery Date such new Note is not delivered.

               (v)  Notices.
                    --------

                      (A)  Immediately upon any adjustment of the Conversion
               Price, the Company will give written notice thereof to each
               Holder of the Notes setting forth in reasonable detail, and
               certifying, the calculation of such adjustment.

                      (B)  The Company will give written notice to each Holder
               of the Notes at least ten (10) days prior to the date on which
               the Company closes its books or takes a record (I) with respect
               to any dividend or distribution upon the Common Stock, (II) with
               respect to any pro rata subscription offer to Holders of Common
               Stock or (III) for determining rights to vote with respect to any
               Organic Change (as defined in Section 4(a)), dissolution or
               liquidation, provided that such information shall be made known
               to the public prior to or in conjunction with such notice being
               provided to each such Holder.

                      (C)  The Company will also give written notice to each
               Holder of the Notes at least ten (10) days prior to the date on
               which any Organic Change, dissolution or liquidation will take
               place, provided that such information shall be made known to the
               public prior to or in conjunction with such notice being provided
               to each such Holder.

     3.   Redemption at Option of Holder.
          ------------------------------

          (a)  Redemption Option Upon Triggering Event. In addition to all other
               ---------------------------------------
     rights of the Holder contained herein, after a Triggering Event (as defined
     below), the Holder shall have the right, at the Holder's option, to require
     the Company to redeem all or a portion of this Note at a price equal to the
     greater of (i) 120% of the Conversion Amount and (ii) the product of (A)
     the Conversion Rate for the Conversion Amount to be redeemed in effect at
     such time as such Holder delivers a Notice of Redemption at Option of Buyer
     (as defined below) and (B) the Weighted Average Price of the Common Stock
     on the date immediately preceding such Triggering Event on which the
     Principal Market, or the market or exchange where the Common Stock is then
     traded, is open for trading ("Redemption Price"); provided, however, for a
     Triggering Event resulting pursuant to Sections 3(b)(vi) or 3(b)(viii)
     below, the holder shall only have the right to redeem that portion of the
     Note which the Company would not be obligated to convert pursuant to
     Section 12 if the entire Conversion Amount of the Note were converted as of
     the applicable date of determination (without regard to any limitation on
     conversion).

          (b)  "Triggering Event".  A "Triggering Event" shall be deemed to have
               ------------------
     occurred at such time as any of the following events:

                                      -11-
<PAGE>

          order) or is unavailable to the Holder for sale of all of such
          Holder's Registrable Securities (as defined in the Registration Rights
          Agreement) in accordance with the terms of the Registration Rights
          Agreement, and such lapse or unavailability continues for a period of

          Agreement) and except, in the case of a breach of a covenant which is
          curable, only if such breach continues for a period of at least 10

               (viii) upon the Company's receipt of a Conversion Notice, the
          Company shall not be obligated to issue shares of Common Stock
          issuable upon such conversion due to the provisions of Section 12.

          (c)  Mechanics of Redemption at Option of Buyer.  Within one (1)
               ------------------------------------------
     Business Day after the occurrence of a Triggering Event, the Company shall
     deliver written notice thereof via facsimile and overnight courier ("Notice
     of Triggering Event") to each Holder of the Notes. At any time after the
     earlier of the Holder's receipt of a Notice of Triggering Event and the
     Holder becoming aware of a Triggering Event, the Holder may require the
     Company to redeem all of such Holder's Notes by delivering written notice
     thereof via facsimile and overnight courier ("Notice of Redemption at
     Option of Buyer") to the Company, which notice shall include the date that
     such notice was given and to the extent such notice is given upon the
     occurrence of a Triggering Event pursuant to Sections 3(b)(iii), 3(b)(v),
     3(b)(vii) and 3(b)(viii) the date which is 120 days after the date that
     such notice is given (which period shall be referred to as "Payment Block
     Period") provided that each Notice of Redemption at Option of Buyer may
     only be sent during the period beginning on the date of the occurrence of
     the Triggering Event and ending on the later of the date which is (i) 45
     days after the date on which such Holder received a Notice of Triggering
     Event from the Company with respect to such event and (ii) the date on
     which such Triggering Event is cured, which Notice of Redemption at Option
     of Buyer shall indicate the Conversion Amount of the Notes that the Holder
     is electing to redeem. Each Buyer hereby agrees to use its best efforts to
     deliver to the Bank (as defined below) a Notice of Redemption at Option of
     Buyer promptly after sending such notice to the Company. Such notice shall
     be sent to the Bank by facsimile at (336) 721-4099 or at such other number
     provided to such Buyer by the Bank in writing at least five (5) Business
     Days prior to such Buyer's sending of a Notice of Redemption at Option of
     Buyer, provided, however, that the failure of such Buyer to send such
     notice to the Bank shall in no way limit or affect such Buyer's rights or
     remedies under this Note.

          (d)  Payment of Redemption Price.  Upon the Company's receipt of a
               ---------------------------
     Notice(s) of Redemption at Option of Buyer from any Holder of Notes, the
     Company shall immediately notify each Holder of Notes by facsimile of the
     Company's receipt of such notices. The Company shall deliver the applicable
     Redemption Price to the Holder within (A) five (5) Business Days after the
     Company's receipt of a Notice of Redemption at Option of Buyer for
     redemptions pursuant to Sections 3(b)(i), 3(b)(ii), 3(b)(iv) and 3(b)(vi)
     and (B) one (1) Business Day after the expiration of the Payment Block
     Period for redemptions pursuant to Sections 3(b)(iii), 3(b)(v), 3(b)(vii)
     and 3(b)(viii); provided that the Holder's Notes shall have been so
     delivered to the Transfer Agent. If more than one Holder of Notes submits
     Notes for redemption and the Company is unable to redeem all of the Notes
     submitted for redemption, the Company shall redeem a pro rata amount from
     each Holder of Notes based on the Conversion Amount represented by the
     Notes submitted for redemption by such Holder relative to the aggregate
     Conversion Amounts of all Notes for redemption by all Holders of Notes.

          (e)  Void Redemption.  In the event that the Company does not pay the
               ---------------
     Redemption Price within the time period set forth in Section 3(d), at any
     time thereafter and until the Company pays such unpaid applicable
     Redemption Price in full, the Holder shall have the option (the "Void
     Optional Redemption Option") to, in lieu of redemption, require the Company
     to promptly return to the Holder the Note that was submitted for redemption
     by such Holder under this Section 3 and for which the applicable Redemption
     Price (together with any interest thereon) has not been paid, by sending
     written notice thereof to the Company via facsimile (the "Void Optional
     Redemption Notice"). Upon the Company's receipt of such Void Optional
     Redemption Notice, (i) the Notice of Redemption at Option of Buyer shall be
     null and void with respect to that portion of the Note subject to the Void
     Optional Redemption Notice, and (ii) the Company shall immediately return
     the Note subject to the Void Optional Redemption Notice, and (iii) the
     Fixed Conversion Price of such portion of the Note shall be adjusted to the
     lesser of (A) the Conversion Price as in effect on the date on which the
     Void Optional Redemption

                                      -13-
<PAGE>

     Notice is delivered to the Company and (B) the lowest Closing Bid Price
     during the period beginning on the date on which the Notice of Redemption
     at Option of Buyer is delivered to the Company and ending on the date on
     which the Void Optional Redemption Notice is delivered to the Company.

          (f)  Disputes; Miscellaneous.  In the event of a dispute as to the
               -----------------------
     determination of the Weighted Average Price, the Closing Bid Price or the
     arithmetic calculation of the Redemption Price, such dispute shall be
     resolved pursuant to Section 2(e)(iii) above with the term "Closing Bid
     Price" being substituted for the term "Weighted Average Price" and the term
     "Redemption Price" being substituted for the term "Conversion Rate". The
     Holder's delivery of a Void Optional Redemption Notice and exercise of its
     rights following such notice shall not effect the Company's obligations to
     make any payments which have accrued prior to the date of such notice. In
     the event of a redemption pursuant to this Section 3 of less than all of
     the Conversion Amount of this Note, the Company shall promptly cause to be
     issued and delivered to the Holder a new Note representing the remaining
     Conversion Amount which has not been redeemed.

     4.  Other Rights of Holders.
         -----------------------

          (a) Reorganization, Reclassification, Consolidation, Merger or Sale.
              ---------------------------------------------------------------
Any recapitalization, reorganization, reclassification, consolidation, merger,
sale of all or substantially all of the Company's assets to another Person or
other transaction which is effected in such a way that Holders of Common Stock
are entitled to receive (either directly or upon subsequent liquidation) stock,
securities or assets with respect to or in exchange for Common Stock is referred
to herein as "Organic Change." Prior to the consummation of any (i) sale of all
or substantially all of the Company's assets to an acquiring Person or (ii)
other Organic Change following which the Company is not a surviving entity, the
Company will secure from the Person purchasing such assets or the successor
resulting from such Organic Change (in each case, the "Acquiring Entity") a
written agreement (in form and substance satisfactory to the Holders of the
Notes representing a majority of the Conversion Amounts of the Notes then
outstanding) to deliver to the Holder in exchange for this Note, a security of
the Acquiring Entity evidenced by a written instrument substantially similar in
form and substance to this Note, and satisfactory to the Holders the Notes
representing a majority of the Conversion Amounts of the Notes then outstanding.
Prior to the consummation of any other Organic Change, the Company shall make
appropriate provision (in form and substance satisfactory to the Holders of
Notes representing a majority of the Conversion Amounts of the Notes then
outstanding) to insure that each of the Holders will thereafter have the right
to acquire and receive in lieu of or in addition to (as the case may be) the
shares of Common Stock immediately theretofore acquirable and receivable upon
the conversion of this Note such shares of stock, securities or assets that
would have been issued or payable in such Organic Change with respect to or in
exchange for the number of shares of Common Stock which would have been
acquirable and receivable upon the conversion of this Note as of the date of
such Organic Change (without taking into account any limitations or restrictions
on the convertibility of this Note).

                                      -14-
<PAGE>

          (b)  Optional Redemption Upon Change of Control.  In addition to the
               ------------------------------------------
rights of the Holder under Section 4(a), upon a Change of Control (as defined
below) of the Company the Holder shall have the right, at the Holder's option,
to require the Company to redeem all or a portion of the Conversion Amount
represented by this Note equal to the Conversion Amount ("Change of Control
Redemption Price"). No sooner than 15 days nor later than 10 days prior to the
consummation of a Change of Control, but not prior to the public announcement of
such Change of Control, the Company shall deliver written notice thereof via
facsimile and overnight courier (a "Notice of Change of Control") to the Holder.
At any time during the period beginning after receipt of a Notice of Change of
Control (or, in the event a Notice of Change of Control is not delivered at
least 10 days prior to a Change of Control, at any time on or after the date
which is 10 days prior to a Change of Control) and ending on the date of such
Change of Control, the Holder may require the Company to redeem all or a portion
of the Conversion Amount of this Note then outstanding by delivering written
notice thereof via facsimile and overnight courier (a "Notice of Redemption Upon
Change of Control") to the Company, which Notice of Redemption Upon Change of
Control shall indicate (i) the Conversion Amount the Holder is submitting for
redemption, and (ii) the applicable Change of Control Redemption Price, as
calculated pursuant to Section this Section 4(b). Upon the Company's receipt of
a Notice(s) of Redemption Upon Change of Control from any Holder of Notes, the
Company shall promptly, but in no event later than one (1) Business Day
following such receipt, notify the Holder of this Note by facsimile of the
Company's receipt of such Notice(s) of Redemption Upon Change of Control. The
Company shall deliver the applicable Change of Control Redemption Price
simultaneous with the consummation of the Change of Control; provided that, if
required by Section 2(e)(viii), this Note shall have been so delivered to the
Company. Payments provided for in this Section 4(b) shall have priority to
payments to other stockholders in connection with a Change of Control. For
purposes of this Section 4(b), "Change of Control" means (i) the consolidation,
merger or other business combination of the Company with or into another Person
(other than (A) a consolidation, merger or other business combination in which
Holders of the Company's voting power immediately prior to the transaction
continue after the transaction to hold, directly or indirectly, the voting power
of the surviving entity or entities necessary to elect a majority of the members
of the board of directors (or their equivalent if other than a corporation) of
such entity or entities, or (B) pursuant to a migratory merger effected solely
for the purpose of changing the jurisdiction of incorporation of the Company),
(ii) the sale or transfer of all or substantially all of the Company's assets,
or (iii) a purchase, tender or exchange offer made to and accepted by the
Holders of more than the 50% of the outstanding shares of Common Stock.

          (c)  Purchase Rights.  If at any time the Company grants, issues or
               ---------------
sells any Options, Convertible Securities or rights to purchase stock, warrants,
securities or other property pro rata to the record Holders of any class of
Common Stock (the "Purchase Rights"), then the Holder will be entitled to
acquire, upon the terms applicable to such Purchase Rights, the aggregate
Purchase Rights which the Holder could have acquired if the Holder had held the
number of shares of Common Stock acquirable upon complete conversion of this
Note (without taking into account any limitations or restrictions on the
convertibility of this Note) immediately before the date on which a record is
taken for the grant, issuance or sale of such Purchase Rights,

                                      -15-
<PAGE>

or, if no such record is taken, the date as of which the record Holders of
Common Stock are to be determined for the grant, issue or sale of such Purchase
Rights.

     5.   Redemption at the Company's Election.  At any time or times during the
          ------------------------------------
period beginning on the Issuance Date and ending on and including the date which
is 549 days after such Issuance Date, the Company shall have the right, in its
sole discretion, to require that some or all of the outstanding Conversion
Amount of the outstanding Notes issued on such Issuance Date be redeemed
("Redemption at Company's Election") for consideration equal to the Conversion
Amount of such Notes to be redeemed on the Company Election Redemption Date (as
defined below) (the "Company's Election Redemption Price"); provided that the
Conditions to Redemption at the Company's Election (as set forth below) are
satisfied.  The Company shall exercise its right to Redemption at Company's
Election by providing each Holder of Notes issued on such Issuance Date written
notice ("Notice of Redemption at Company's Election") at least 15 Business Days
but not more than 20 Business Days prior to the date of consummation of such
redemption ("Company's Election Redemption Date").  If the Company elects to
require redemption of some, but not all, of the Conversion Amount of the Notes
issued on the Issuance Date then outstanding, the Company shall require
redemption of the pro rata amount from each Holder of such Notes based on the
principal amount of Notes purchased by such Holder on the Issuance Date relative
to the aggregate principal amount of all Notes purchased on such Issuance Date
(such amount with respect to the Holder being referred to herein as its "Pro
Rata Redemption Amount").  The Notice of Redemption at Company's Election shall
indicate (x) the Conversion Amount of the Notes the Company has elected to
redeem from all Holders of Notes, (y) the Company's Election Redemption Date,
and (z) each Holder's pro rata share of Conversion Amounts of the Notes selected
for redemption as determined in accordance with the immediately preceding
sentence.  If the Company has exercised its right of Redemption at Company's
Election and the conditions of this Section 5, including the Conditions to
Redemption at Company's Election, have been satisfied, then each Holder's Pro
Rata Redemption Amount shall be redeemed as of the Company's Election Redemption
Date by payment by the Company to each Holder of the Notes of the Company's
Election Redemption Price.  If required by Section 2(e)(viii), all Holders of
the Notes shall thereupon and within two (2) Business Days after the Company's
Election Redemption Date or such earlier date as the Company and each Holder of
Notes mutually agree, surrender all Notes being redeemed on such date to the
Company.  If the Company fails to pay the full Company's Election Redemption
Price with respect to this Note  then the Redemption at Company's Election shall
be null and void with respect to this Note and the Holder shall be entitled to
all the rights of a Holder of outstanding Notes.  "Conditions to Redemption at
the Company's Election" means the following conditions:  (i) during the period
beginning on the Issuance Date and ending on and including the Company's
Election Redemption Date, the Company shall have delivered Conversion Shares
upon conversion of the Notes to the Holders of the Notes on a timely basis as
set forth in Section 2(e)(ii) of this Note; (ii) on each day during the period
beginning 30 days prior to the date of Notice of Redemption at Company's
Election and ending on and including the Company's Election Redemption Date the
Registration Statement shall be effective and available for the sale of at least
all of the Registrable Securities (as defined in the Registration Rights
Agreement); (iii) on each day during the period beginning 30 days prior to the
date of  Notice of Redemption at Company's Election and ending on and including
the Company's Election Redemption Date, the Common Stock is designated for
quotation on the Nasdaq National

                                      -16-

trading (excluding suspensions of not more than one day resulting from business
announcements by the Company); and (iv) during the period beginning on the
Issuance Date and ending on and including the Company's Election Redemption
Date, there shall not have occurred a Triggering Event (which in the case of a
Triggering Event pursuant to Section 3(d)(vii) hereof, has not been cured or
waived) or an event that with the passage of time would constitute a Triggering
Event, assuming it is not cured. Notwithstanding the above, but subject to
Section 2(d) and Section 7, the Holder may convert any Conversion Amount
(including Conversion Amounts selected for redemption) into Common Stock
pursuant to Section 2(a) on or prior to the date immediately preceding the
Company's Election Redemption Date. If the Company fails to timely pay any
Company's Election Redemption Price in accordance with this Section 5, then the
Company shall not be permitted to submit another Notice of Redemption at
Company's Election without the prior written consent of the Holders of the Notes
representing at least two-thirds (2/3) of the Conversion Amounts of the Notes
then outstanding.

     6.  Conversion at the Company's Election.  On any date during the period
         ------------------------------------
beginning on the date which is 30 days after the Registration Statement has been
declared effective by the SEC and ending on the date which is 549 days after the
Issuance Date of this Note, the Company shall have the right, in its sole
discretion, to require that all or portion of the outstanding Conversion Amount
of this Note be converted ("Company's Conversion Election") at the applicable
Conversion Rate; provided that the Conditions to Conversion at the Company's
Election (as set forth below) are satisfied.  The Company shall exercise its
right to Company's Conversion Election by providing each Holder of the Notes
written notice ("Company's Conversion Election Notice") on such date by
facsimile and overnight courier.  The date on which each of the Holders of the
Notes issued on the Issuance Date receives the Company's Conversion Election
Notice is referred to in this Note as the "Company's Conversion Election Notice
Date").  If the Company elects to require conversion of some, but not all, of
the Conversion Amounts of the Notes issued on the Issuance Date then
outstanding, the Company shall require conversion of the pro rata amount from
each Holder of such Notes based on the principal amount of Notes purchased by
such Holder on the Issuance Date relative to the aggregate principal amount of
all Notes purchased on such Issuance Date (such amount with respect to the
Holder being referred to herein as its "Pro Rata Conversion Amount").  The
Company's Conversion Election Notice shall indicate (x) the Conversion Amount of
Notes held by each Holder of Notes the Company has selected for conversion, (y)
the date selected by the Company for conversion ("Company's Election Conversion
Date"), which date shall be not less than 20 or more than 60 Business Days after
the Company's Conversion Election Notice Date, and (z) each Holder's pro rata
share of Conversion Amounts of the Notes selected for conversion as determined
in accordance with the immediately preceding sentence.  Subject to the
satisfaction of all the conditions of this Section 6, on the Company's Election
Conversion Date the Holder of this Note will be deemed to have submitted a
Conversion Notice in accordance with Section 2(e)(i) for a Conversion Amount
equal to the result of (a) the Holder's Pro Rata Conversion Amount, minus (b)
the Conversion Amount of this Note converted by the Holder during the Company's
Mandatory Conversion Period (as defined below); provided, however, in no event
shall the Holder be required to convert a Conversion Amount during any Company's
Mandatory Conversion Period into a number of shares of Common Stock in excess of
the pro rata amount (determined

                                      -17-
<PAGE>

in the same manner as the Pro Rata Conversion Amount above) of 15% of the
trading volume of the Common Stock on the Principal Market (as reported by
Bloomberg) during the Company's Mandatory Conversion Period. The Company may
terminate a Conversion at Company's Election prior to the Company's Election
Conversion Date with respect to Conversion Amounts not submitted for conversion
prior to the effective date of such termination by delivering written notice
("Company's Mandatory Conversion Period Termination Notice") to each Holder of
Notes issued on the Issuance Date at least five Business Days prior to the
effective date of such termination, provided that the Company has not previously
delivered two Company's Mandatory Conversion Period Termination Notices.
"Conditions to Conversion at the Company's Election" means the following
conditions: (i) on each day during the period beginning the date the SEC

constitute a Triggering Event, or (C) the public announcement of a pending

Conversion Amounts of the Notes issued on the Issuance Date selected for
conversion by the Company as reflected in the Company's Conversion Election
Notice is at least $300,000; (v) during the period beginning on the Issuance

Warrants, respectively; and (vi) the Company otherwise has satisfied its
obligations and is not in default under this Note, the Securities Purchase

Common Stock on the date of issuance of such options, (E) the issuance of Common
Stock or warrants to purchase Common Stock as consideration for an acquisition
which shall be disclosed on a Form 8-K prior to or concurrent with the Form 8-K
required to be filed pursuant to Section 4(l) of the Securities Purchase
Agreement disclosing the Securities Purchase Agreement and the related
transactions, (F) a firm commitment, underwritten public offering, provided that
within three days of the closing of such underwritten public offering the
Company will have delivered to the Holder a Notice of Redemption at Company's
Election requiring the Company to redeem the remaining outstanding Conversion
Amount of such Holder's Note and the Company shall have fulfilled all of its
obligations under Section 5 within 20 Business Days of delivering such Notice of
Redemption of Company Election, with respect to a Conversion Amount of this Note
equal to the lesser of (I) the Holder's pro rata amount (determined as in

issuance or sale and (II) the Conversion Amount of this Note then outstanding,
and (G) the issuance of up to 500,000 shares of the Company's Common Stock as
consideration in a merger or consolidation or for the acquisition of a business,
product, license or other asset by the Company, provided that the issuance price
of such shares of Common Stock is not less than the market price of the Common
Stock on the date of issuance; (h) on and after January 31, 2000 if the Company
fails to hold a meeting of its Stockholders for the purpose of approving the
issuance of the Conversion Shares upon conversion of the Notes and the Warrant
Shares (as defined in the Securities Purchase

                                      -19-
<PAGE>

Agreement) upon exercise of the Warrants in accordance with Section 4(k) of the
Securities Purchase Agreement and the applicable laws and the rules and
regulations of the Nasdaq National Market on or prior to January 31, 2000, or
such a meeting of stockholders is held on or prior to such date but the
stockholders fail to approve of such proposal; or (i) on and after the date
which is 15 months after the Initial Closing Date if there remains outstanding
at least 75% of the aggregate original principal amounts of all Notes issued by
the Company pursuant to this Agreement and the Company's unrestricted cash, as
reflected on the balance sheet included in the Company's most recent Form 10-Q,
is less than the aggregate Conversion Amounts of all Notes outstanding on the
date which is 15 months after the Initial Closing Date, then with respect to a
Conversion Amount equal to 25% of the aggregate original principal amounts (plus
accrued interest thereon) of the Notes issued to the Holder of this Note
pursuant to the Securities Purchase Agreement.

     8.  Reservation of Shares.  The Company shall, so long as any principal
         ---------------------
amount of the Note is outstanding, reserve and keep available out of its
authorized and unissued Common Stock, solely for the purpose of effecting the
conversion of the Notes, such number of shares of Common Stock as shall from
time to time be sufficient to effect the conversion of all of the principal
amount of the Notes then outstanding; provided that the number of shares of
Common Stock so reserved shall at no time be less than 200% of the number of
shares of Common Stock for which the principal amount of the Notes are at any
time convertible.  The initial number of shares of Common Stock reserved for
conversions of the Notes and each increase in the number of shares so reserved
shall be allocated pro rata among the Holders of the Notes based on the
principal amount of the Notes held by each Holder at the time of issuance of the
Notes or increase in the number of reserved shares, as the case may be.  In the
event a Holder shall sell or otherwise transfer any of such Holder's Notes, each
transferee shall be allocated a pro rata portion of the number of reserved
shares of Common Stock reserved for such transferor.  Any shares of Common Stock
reserved and allocated to any Person which ceases to hold any Notes shall be
allocated to the remaining Holders, pro rata based on the principal amount of
the Notes then held by such Holders.

     9.  Voting Rights; Rank.  Holders shall have no voting rights, except as
         -------------------
required by law, including but not limited to the General Corporation Law of the
State of Delaware, and as expressly provided in this Note.  Payments of
principal and interest and other payments due under this Note, except as
otherwise provided herein, shall rank pari passu with and shall not be
subordinated to any other unsecured debt obligations of the Company.

     10.  Restriction on Redemption and Cash Dividends.  Until all of the
          --------------------------------------------
Conversion Amount of this Note has been converted, redeemed or otherwise
satisfied as provided herein, the Company shall not, directly or indirectly,
redeem, or declare or pay any cash dividend or distribution on, its capital
stock without the prior express written consent of the Holders of Notes
representing at least fifty-one percent (51%) of the Conversion Amount of the
Notes then outstanding, except for payments on convertible securities of the
Company outstanding on the Issuance Date pursuant to the terms of such
convertible securities as in effect on the Issuance Date.

                                      -20-
<PAGE>

     11.  Restriction on Hedging Activity.  Subject to the exceptions described
          -------------------------------
below, during the period beginning on the Initial Closing Date (as defined in
the Securities Purchase Agreement) and ending on the date which is 549 days
after the Initial Issuance Date, neither such Buyer nor any of its affiliates
shall engage, directly or  indirectly, in any transaction constituting a "short
sale" (as defined in rule 3b-3 of the Securities Exchange Act of 1934, as
"Short Sales"); provided, however, that the Holder and its affiliates are
entitled to engage in transactions which constitute Short Sales to the extent
that following such transaction the aggregate short position of the Holder and
its affiliates does not exceed the sum of (a) the number shares of Common Stock
equal to the number of shares of Common Stock the Holder and its affiliates have
the right to acquire upon exercise of the Warrants held by the Holder and its
affiliates (without regard to any limitations on exercises of the Warrants),
plus (b) during the period beginning the first day of a Company Mandatory
Conversion Period and ending on and including the date which is last day of such
Company Mandatory Conversion Period, that number of shares of Common Stock equal
to the quotient of (i) the Conversion Amount set forth in a Company's Notice of
Mandatory Conversion for such Holder and its affiliates with respect to such
Company Mandatory Conversion Period, divided by (ii) 95% of the average of the
Weighted Average Price of the Common Stock on each trading day during the period
beginning on the first day of such Company Mandatory Conversion Period and
ending on and including the earlier of (A) the last trading day of such Company
Mandatory Conversion Period and (B) the date as of which the determination is
being made for purposes of this Section 11.  Notwithstanding the foregoing, the
restriction on Short Sales set forth in the first sentence of this Section 11
shall not apply (I) on and after the first date on which there shall have
occurred a Triggering Event or an event that with the passage of time would
constitute a Triggering Event, assuming it is not cured, (II) on and after
January 31, 2000, if the Company fails to hold a meeting of its stockholders for
the purpose of approving the issuance of the Conversion Shares upon conversion
of the Notes and the Warrant Shares upon exercise of the Warrants in accordance
with Section 4(k) of the Securities Purchase Agreement and the applicable laws
and the rules and regulations of the Nasdaq National Market on or prior to
January 31, 2000, or such a meeting of stockholders is held on or prior to such
date but the stockholders fail to approve of such proposal and (III) on or after
any date on which the Company issues or sells or is deemed to have issued or
sold any Convertible Securities that are convertible into or exercisable or
exchangeable for shares of Common Stock at a Variable Price, unless such
Variable Price is subject to a minimum price, which minimum price is not subject
to adjustment and is greater than the Fixed Conversion Price.

     12.  Limitation on Number of Conversion Shares.  The Company shall not be
          -----------------------------------------
obligated to issue any shares of Common Stock upon conversion of this Note if
the issuance of such shares of Common Stock would exceed that number of shares
of Common Stock which the Company may issue upon Conversion of this Note (the
"Exchange Cap") without breaching the Company's obligations under the rules or
regulations of the Principal Market, or the market or exchange where the Common
Stock is then traded, except that such limitation shall not apply in the event
that the Company (a) obtains the approval of its stockholders as required by the
applicable rules of the Principal Market, or the market or exchange where the
Common Stock is then traded, (or any successor rule or regulation) for issuances
of Common Stock in excess of such amount, or (b) obtains a written opinion from
outside counsel to the Company that such approval is not

                                      -21-
<PAGE>

required, which opinion shall be reasonably satisfactory to the Holders of a
majority of the principal amount of the Notes then outstanding. Until such
approval or written opinion is obtained, or such action is taken by the required
number of Holders of the Notes, no purchaser of Notes pursuant to the Securities
Purchase Agreement (the "Purchasers") shall be issued, upon conversion of this
Note, shares of Common Stock in an amount greater than the product of (i) the
Exchange Cap amount multiplied by (ii) a fraction, the numerator of which is the
principal amount of the Notes issued to such Purchaser pursuant to the
Securities Purchase Agreement and the denominator of which is the aggregate
principal amount of all Notes issued to the Purchasers pursuant to the
Securities Purchase Agreement (the "Cap Allocation Amount"). In the event that
any Purchaser shall sell or otherwise transfer any of such Purchaser's Notes,
the transferee shall be allocated a pro rata portion of such Purchaser's Cap
Allocation Amount. In the event that any Holder of Notes, shall convert all of
such Holder's Notes into a number of shares of Common Stock which, in the
aggregate, is less than such Holder's Cap Allocation Amount, then the difference
between such Holder's Cap Allocation Amount and the number of shares of Common
Stock actually issued to such Holder shall be allocated to the respective Cap
Allocation Amounts of the remaining Holders of Notes on a pro rata basis in
proportion to Conversion Amount of Notes then held by each such Holder.

     13.  Reissuance of Notes.  Subject to Section 2(e)(viii) in the event of a
          -------------------
conversion or redemption pursuant to this Note of less than all of the
Conversion Amount represented by this Note, the Company shall promptly cause to
be issued and delivered to the Holder, upon tender by the Holder of the Note
converted or redeemed, a new note of like tenor representing the remaining
principal amount of this Note which has not been so converted or redeemed.

     14.  Defaults and Remedies.
          ---------------------

          (a)  Events of Default.  An "Event of Default" is:  (i) default for
               -----------------
     thirty (30) days in payment of interest or Default Interest on this Note on
     or after the Maturity Date; (ii) default in payment of the principal amount
     of this Note when and as due; (iii) failure by the Company for thirty (30)
     days after notice to it to comply with any other material provision of this
     Note; (iv) any default under or acceleration prior to maturity of any
     mortgage, indenture or instrument under which there may be issued or by
     which there may be secured or evidenced any indebtedness for money borrowed
     of at least $500,000 by the Company or for money borrowed the repayment of
     at least $500,000 of which is guaranteed by the Company, whether such
     indebtedness or guarantee now exists or shall be created hereafter, (v) if
     the Company pursuant to or within the meaning of any Bankruptcy Law; (A)
     commences a voluntary case; (B) consents to the entry of an order for
     relief against it in an involuntary case; (C) consents to the appointment
     of a Custodian of it or for all or substantially all of its property; (D)
     makes a general assignment for the benefit of its creditors; or (E) admits
     in writing that it is generally unable to pay its debts as the same become
     due; or (vi) a court of competent jurisdiction enters an order or decree
     under any Bankruptcy Law that:  (1) is for relief against the Company in an
     involuntary case; (2) appoints a Custodian of the Company or for all or
     substantially all of its property; or (3) orders the liquidation of the
     Company or any subsidiary, and the order or decree remains unstayed and in
     effect for ninety (90) days.  The Term "Bankruptcy

                                      -22-
<PAGE>

     Law" means Title 11, U.S. Code, or any similar Federal or State Law for the
     relief of debtors. The term "Custodian" means any receiver, trustee,
     assignee, liquidator or similar official under any Bankruptcy Law.

          (b)  Remedies.  If an Event of Default occurs and is continuing, the
               --------
     Holder of this Note may declare all of this Note, including any interest
     and Default Interest and other amounts due, to be due and payable
     immediately, except that in the case of an Event of Default arising from
     events described in clauses (iv) and (v) of Section 13(a), this Note shall
     become due and payable without further action or notice.  Holder may not
     enforce the provisions of this Section 14 except as provided in this
     Section 14.  In addition to any remedy such Holder of the Notes may have
     under this Note and the Securities Purchase Agreement, such unpaid amount
     shall bear interest at the rate of 1.5% per month (prorated for partial
     months) until paid in full

     15.  Vote to Change the Terms of  Notes.  This Note and any provision
          ----------------------------------
hereof may only be amended by an instrument in writing signed by the Company and
Holders of a majority of the aggregate Conversion Amount of the Notes then
outstanding.  The term "Note" and all reference thereto, as used throughout this
instrument, shall mean this instrument (and the other Notes issued pursuant to
the Securities Purchase Agreement) as originally executed, or if later amended
or supplemented, then as so amended or supplemented.

     16.  Lost or Stolen Notes.  Upon receipt by the Company of evidence
          --------------------
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Note, and, in the case of loss, theft or destruction, of an indemnification
undertaking by the Holder to the Company in a form reasonably acceptable to the
Company and, in the case of mutilation, upon surrender and cancellation of the
Notes, the Company shall execute and deliver new notes of like tenor and date;
provided, however, the Company shall not be obligated to re-issue notes if the
Holder contemporaneously requests the Company to convert such remaining
principal amount into Common Stock.

     17.  Payment of Collection, Enforcement and Other Costs.  If: (i) this Note
          --------------------------------------------------
is placed in the hands of an attorney for collection or enforcement or is
collected or enforced through any legal proceeding; or (ii) an attorney is
retained to represent the Holder of this Note in any bankruptcy, reorganization,
receivership of the Company or other proceedings affecting Company creditors'
rights and involving a claim under this Note.

     18.  Cancellation.  After all principal and accrued interest at any time
          ------------
owed on this Note has been paid in full, this Note shall automatically be deemed
canceled, shall be surrendered to the Company for cancellation and shall not be
reissued.

     19.  Note Exchangeable for Different Denominations.  This Note is
          ---------------------------------------------
exchangeable, upon the surrender hereof by the Holder at the principal office of
the Company, for a new Note or Notes (in principal amounts of at least $100,000)
containing the same terms and conditions and representing in the aggregate the
principal amount of this Note, and each such new Note will represent such
portion of such principal amount as is designated by the Holder at the time of
such

                                      -23-
<PAGE>

surrender. The date the Company initially issues this Note will be deemed to be
the "Issuance Date" hereof regardless of the number of times a new Note shall be
issued.

     20.  Waiver of Notice.  To the extent permitted by law, the Company hereby
          ----------------
waives demand, notice, protest and all other demands and notices in connection
with the delivery, acceptance, performance, default or enforcement of this Note
and the Securities Purchase Agreement.

     21.  Governing Law.  This Note shall be construed and enforced in
          -------------
accordance with, and all questions concerning the construction, validity,
interpretation and performance of this Note shall be governed by, the laws of
the State of New York, without giving effect to provisions thereof regarding
conflict of laws.

     22.  Remedies, Characterizations, Other Obligations, Breaches and
          ------------------------------------------------------------
Injunctive Relief.  The remedies provided in this Note shall be cumulative and
- -----------------
in addition to all other remedies available under this Note, at law or in equity
(including a decree of specific performance and/or other injunctive relief), no
remedy contained herein shall be deemed a waiver of compliance with the
provisions giving rise to such remedy and nothing herein shall limit a Holder's
right to pursue actual damages for any failure by the Company to comply with the
terms of this Note.  The Company covenants to each Holder of Notes that there
shall be no characterization concerning this instrument other than as expressly
provided herein.  Amounts set forth or provided for herein with respect to
payments, conversion and the like (and the computation thereof) shall be the
amounts to be received by the Holder thereof and shall not, except as expressly
provided herein, be subject to any other obligation of the Company (or the
performance thereof).  The Company acknowledges that a breach by it of its
obligations hereunder will cause irreparable harm to the Holders of the Notes
and that the remedy at law for any such breach may be inadequate.  The Company
therefore agrees that, in the event of any such breach or threatened breach, the
Holders of the Notes shall be entitled, in addition to all other available
remedies, to an injunction restraining any breach, without the necessity of
showing economic loss and without any bond or other security being required.

     23.  Specific Shall Not Limit General; Construction.  No specific provision
          ----------------------------------------------
contained in this Note shall limit or modify any more general provision
contained herein.  This Note shall be deemed to be jointly drafted by the
Company and all Holders and shall not be construed against any person as the
drafter hereof.

     24.  Failure or Indulgence Not Waiver.  No failure or delay on the part of
          --------------------------------
this Note in the exercise of any power, right or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such power, right or privilege preclude other or further exercise thereof or of
any other right, power or privilege.

     25.  Notices.  Whenever notice is required to be given under this Note,
          -------
unless otherwise provided herein, such notice shall be given in accordance with
Section 9(f) of the Securities Purchase Agreement.

                                      -24-

     26.  Subordination Provisions Generally.
          ----------------------------------

          (a) Subject to the provisions of this Section 26 and Section 27
hereof, this Note is hereby made and declared to be subject and subordinate to

"Bank") pursuant to that certain loan agreement dated as of December 31, 1998
between the Company and the Bank as amended by the amendment to loan agreement
dated June 14, 1999, and that certain loan agreement dated December 31, 1998
between the Lessor and the Bank (the "Loan Agreement") whether now existing or
hereafter incurred, including, without limitation, all principal (up to but not
exceeding Twenty-Five Million Dollars ($25,000,000)), accrued interest
(including interest accruing after the date on which the Company becomes subject
to any federal or state debtor relief statute, whether or not recoverable
against the Company or the Lessor), collection costs and other fees or expenses
incurred by the Bank in connection therewith, (collectively, the "Senior Debt").
The Bank may, at any time, in its discretion, renew, modify, or extend the time
for payment of all or any portion of the Senior Debt, or waive or release any
collateral which may be held therefor, or enter into any other agreement with
the Company and or the Lessor as Bank may deem desirable, all without any notice
to or any assent from the Holder and without in any way affecting Bank's rights
hereunder, providing, however, that the Bank shall not, either through
amendment, waiver, or separate agreement exceed the existing maximum debt limit
of $25,000,000 under the Senior Debt.

          (b)  Subject to the provisions set forth in Section 27 below limiting
     the extent of the subordination provisions set forth herein, the Holder
     hereof agrees that:

               (i) it will not ask, demand, sue for, take, receive or accept any
          payment in cash of or under this Note;

               (ii) it will not exercise any right or option hereunder to redeem
          in cash all or any part of this Note at or prior to the maturity
          hereof, unless and until the Senior Debt shall have been fully and
          indefeasibly paid and discharged; and

               (iii)  if any payment is received by the Holder on account of
          this Note prior to such full payment of this Note, such payment shall
          be held in trust by

                                      -25-

<PAGE>

     the Holder for the benefit of the Bank, and shall be delivered to the Bank
     in kind (with any necessary indorsement or instrument of transfer) to be
     applied to the Senior Debt.

          (c) Upon the distribution of any of the Company's assets, whether by
     reason of sale, reorganization, liquidation, dissolution, arrangement,
     bankruptcy, receivership, assignment for the benefit of creditors,
     foreclosure or otherwise, the Bank shall be entitled to receive payment in
     full of the Senior Debt prior to the payment of all or any part of this
     Note.  Bank is hereby irrevocably appointed attorney-in-fact for the Holder
     for the purpose of making, presenting, filing and voting such proofs of
     claim against the Company on account of all or any part of this the
     indebtedness represented by this Note as Bank deems advisable, but, such
     power of attorney does not include, nor is it intended to include, any
     ability of the Bank to amend the terms of this Note or exercise any of the
     conversion rights set forth herein.

          (d) So long as the Senior Debt is outstanding, the Holder will not,
     without the prior written consent of the Bank commence or join with any
     other creditor in commencing any bankruptcy, reorganization or insolvency
     proceeding against the Company, unless the Bank has already commenced such
     a proceeding or the Company has voluntarily initiated its own such
     proceeding.

          (e) The subordination of this Note is continuing and irrevocable, and
     is binding upon and enforceable against the Company, the Holder, and their
     successors and assigns, and shall extend to and for the benefit of the
     Bank, and any other holder of the Senior Debt.  The Company acknowledges
     that any attempted or purported termination by the Company of the
     subordination provisions of this Note shall constitute a default under the
     Senior Debt.  Any Note that renews, replaces, substitutes for or supercedes
     this Note, in whole or in part, and any modification or amendment hereof,
     shall be deemed to be subject to the subordination provisions set forth
     hereinabove, and the Company agrees that is will not issue any such Note,
     or modify or amend this Note, without the prior written approval of the
     Bank.

     27.  Limitations on Subordination Provisions Generally.  The subordination
provisions set forth in Section 26 above are limited to the extent set forth in
this Section 27:

          (a) Each of the Company and the Holder may exercise any conversion
     right or option under this Note pursuant to which all or any portion of the
     Conversion Amount of this Note may be converted to Common Stock of the
     Company.

          (b) The subordination provisions set forth in Section 26 above shall
     not, and are not intended to, prohibit the Holder of this Note from giving
     the Company notice of the occurrence of an Event of Default, a Triggering
     Event or of the intention of the Holder to convert all or a portion of the
     balance due under this Note into Common

                                      -26-
<PAGE>

     Stock.

          (c) Notwithstanding the subordination provisions set forth in Section
     26 above, upon the occurrence of a Triggering Event under Sections 3(b)(i),
     3(b)(ii), 3(b)(iv) or 3(b)(vi), the Holder may give a Notice of Redemption
     at Option of Buyer and the Holder shall be entitled to exercise all of its
     remedies hereunder, and the Company shall honor its obligations under this
     Note, including, without limitation, its obligations under Section 3
     hereof.  The Holder shall be entitled to retain for its own account,
     without regard to the subordination provisions set forth herein and without
     any obligation to account to the Bank, any amounts paid to the Holder by
     the Company pursuant to Section 3 hereof as a result of such Triggering
     Events or without any obligation to hold in trust for the Bank, any such
     amounts so received.

          (d) Notwithstanding the subordination provisions set forth in Section
     26 above, upon the occurrence of a Triggering Event under Sections
     3(b)(iii), 3(b)(v), 3(b)(vii) or 3(b)(viii), the Holder may give a Notice
     of Redemption at Option of Buyer. Any amounts received by the Holder during
     such Payment Block Period shall be subject to the provisions of Section 26
     above. Upon the expiration of any Payment Block Period, and so long as the
     Company is not the subject of any bankruptcy or insolvency proceeding, the
     Holder shall be entitled to receive any amounts paid by the Company
     hereunder without any obligation to account to the Bank for any such
     amounts or without any obligation to hold in trust for the Bank, any such
     amounts so received.

          contained in this Agreement); and

          contained in this Agreement).
