                            INVESTOR RIGHTS AGREEMENT

         This Investor Rights Agreement dated as of June 15, 2001 is entered
into by and among Blue Rhino Corporation, a Delaware corporation (the
"Corporation"), Allied Capital Corporation, a Maryland corporation ("Allied")
and the stockholders of the Corporation listed on Exhibit A hereto
(collectively, the "Stockholders" and individually, a "Stockholder").

                                    Recitals

         A. The Corporation, Allied and certain subsidiaries of the Corporation
have entered into an Investment Agreement of even date herewith (the "Investment
Agreement"), whereby the Corporation shall issue and sell, and Allied shall
purchase, subordinated debentures (the "Debentures") in the aggregate principal
amount of $15,000,000 and a warrant (the "Warrant" and to the extent divided,
collectively, the "Warrants") to purchase up to 1,372,071 shares (the "Warrant
Shares") of common stock, par value $.001 per share, of the Corporation ("Common
Stock");

         B. The execution of this Agreement is a condition to the obligations of
Allied under the Investment Agreement and the parties hereto are willing to
execute this Agreement and to be bound by the provisions hereof; and

         C. The Corporation, Allied and the Stockholders desire to provide for
certain arrangements with respect to (i) information rights, (ii) registration
rights, (iii) special rights of the Investors (as defined herein), and (iv)
other related matters;

         NOW, THEREFORE, in consideration of the mutual promises and covenants
contained in this Agreement, the parties hereto agree as follows:

         1. Definitions. Capitalized terms used herein, but not defined herein,
shall have the respective meanings as set forth in the Investment Agreement. As
used in this Agreement, the following terms shall have the following respective
meanings:

                  1.1 "Equity Issuance" means the issuance by the Corporation or
any of its Subsidiaries of any equity securities to any Person (other than: (a)
any securities issued in connection with a stock split, reverse stock split,
stock dividend or reclassification or similar organic change involving the
Corporation's Capital Stock; (b) any securities issuable upon conversion,
exercise or exchange of securities outstanding or issued as of the date hereof;
(c) warrants, options or other rights to purchase securities or securities
convertible into or exchangeable for securities issued to employees, officers,
directors, distributors, consultants or other persons performing services for or
on behalf of the Corporation (or securities issued upon exercise or conversion
thereof) in each case to the extent issued solely in its status as such and not
as part of an offering of the Corporation's securities, pursuant to any stock
option plan, stock purchase plan, management incentive plan, consulting
agreement or other contract or arrangement approved by the board of directors of
the Corporation; (d) any securities issuable as

                                      -1-
<PAGE>   2

an inducement to lenders of the Corporation to advance sums or otherwise to make
financial accommodations, or as compensation to lenders for advancing sums or
otherwise making financial accommodations, to the Corporation or one or more of
its Subsidiaries, to the extent such issuance is approved by the board of
directors of the Corporation; (e) any securities issuable as compensation to
vendors or lessors of the Corporation in connection with, or as an inducement to
vendors or lessors of the Corporation to enter into, agreements with the
Corporation and not as part of an offering of the Corporation's securities, to
the extent such issuance is approved by the board of directors of the
Corporation; (f) any securities issued solely in consideration for the
acquisition (by merger, consolidation, purchase or otherwise) by the Corporation
of the assets or capital stock or other equity interests of, or in connection
with a joint venture with, any other entity or business segment of any other
entity, to the extent such issuance is approved by the board of directors of the
Corporation; provided, that such issuance (after giving effect thereto), when
aggregated with all other issuances contemplated by this clause (f), does not
constitute a number of shares of Common Stock (on a fully diluted, as-converted
basis and as equitably adjusted in the event of a stock split, reverse stock
split, stock dividend, combination or other similar recapitalization) greater
than 1,577,020).

                  1.2 "Fair Market Value" shall have the meaning set forth in
Section 3.2(c).

                  1.3 "Investors" means Allied and any other holder of the
Warrants or any Warrant Shares, who acquired the Warrants or the Warrant Shares
other than in a public offering.

                  1.4 "Registrable Securities" means: (i) all of the shares of
Common Stock constituting Warrant Shares; and (ii) all of the shares of Common
Stock issued or issuable, directly or indirectly, with respect to the securities
referred to in clause (i) by way of a stock dividend or stock split in
connection with a combination of shares, recapitalization, merger, consolidation
or other reorganization. As to any particular Registrable Securities of a
holder, such securities will cease to be Registrable Securities upon the earlier
of (a) when they have been registered under the Securities Act, (b) the later of
five years or such time as they are transferable without limitation or
restriction by the holder thereof in a single brokerage transaction under the
provisions of Rule 144 or any similar rule then in effect, or (c) if the Warrant
Shares issued or issuable to the Investors constitute less than 3% of the Common
Stock outstanding on the date such determination is made, such time as they are
transferable without limitation or restriction by the holder thereof in a single
brokerage transaction under the provisions of Rule 144 or any similar rule then
in effect.

                  1.5 "SEC" means the U.S. Securities and Exchange Commission.

                  1.6 "Securities Act" means the Securities Act of 1933, as
amended, or any successor federal statute, and the rules and regulations of the
SEC issued under such Act, as they each may, from time to time, be in effect.

         2. Registration Rights.

                  2.1 Effective Date. The rights of the Investors that hold
Registrable Securities under this Section 2, (i) are effective as of the date
hereof, and (ii) shall remain in full force and

                                      -2-
<PAGE>   3

effect for so long as any Investor continues to hold any Registrable Securities.

                  2.2 Demand Registrations.

                           (a) REQUESTS FOR REGISTRATION. Subject to
subparagraphs (b), (c) and (d) of this Section 2.2, the holders of not less than
the portion of the outstanding Registrable Securities as set forth in
subparagraphs (c) and (d) of this Section 2.2 may at any time, request
registration under the Securities Act of all or part of their Registrable
Securities on Form S-1 or any similar long-form registration ("Long-Form
Registrations"), or on Form S-3 or any similar short-form registration ("Short
Form Registrations"), if available, and the Corporation shall use its best
efforts to have such registration statement declared effective as soon as
practicable after the filing date. Each request for such registration must
specify the number of Registrable Securities requested to be registered and the
minimum desired price per share in such offering. Within 10 days after receipt
of any such request, the Corporation will give written notice (the "Notification
of a Demand") of such request to all other holders of Registrable Securities and
will include in such registration all Registrable Securities with respect to
which the Corporation has received written requests for inclusion therein within
20 days after the receipt of the Corporation's notice. All registrations
requested pursuant to this subparagraph (a) are referred to herein as "Demand
Registrations."

                           (b) LIMIT ON NUMBER OF DEMAND REGISTRATIONS. The
holders of Registrable Securities shall be limited (i) to one Long-Form
Registration under Section 2.2(d) and (ii) to no more than two Short-Form
Registrations under Section 2.2(a) during any consecutive 12-month period.

                           (c) LONG-FORM REGISTRATIONS. Subject to the
limitation imposed under Section 2.2(b), the holders of at least 50% of the
Registrable Securities then outstanding will be entitled to request a Demand
Registration; provided, however, that the anticipated aggregate offering price
of the Registrable Securities requested to be registered in any Long-Form
Registration must equal at least $5,000,000. Except as provided in Section
2.6(a), a registration will not count as the permitted Demand Registration until
it has become effective and only if the holders of Registrable Securities are
able to register and sell at least 90% of the Registrable Securities requested
to be included in such registration.

                           (d) SHORT-FORM REGISTRATIONS. Subject to the
limitation imposed under Section 2.2(b) and in addition to the right to request
a Demand Registration under Section 2.2(c), the holders of at least 25% of the
Registrable Securities then in existence will be entitled to request a
Short-Form Registration (if available); provided, however, that the anticipated
aggregate offering price of the Registrable Securities requested to be
registered in any Short-Form Registration must equal at least $500,000.

                           (e) PRIORITY ON DEMAND REGISTRATIONS. The Corporation
will not include in any Demand Registration any securities (other than
securities included pursuant to contractual registration rights outstanding on
the date hereof) that are not Registrable Securities without the prior written
consent of the holders of at least 75% of the Registrable Securities requesting
such registration. If a Demand Registration is an underwritten offering and the

                                      -3-
<PAGE>   4

managing underwriters advise the Corporation in writing that in their opinion
the number of Registrable Securities and other securities requested to be
included therein exceeds the number of Registrable Securities and other
securities which can be sold in such offering without adversely affecting the
marketability of the offering allocated, the Corporation will include in such
registration, prior to the inclusion of other securities, the number of
Registrable Securities, and other securities held by Persons with contractual
registration rights outstanding on the date hereof, requested to be included,
which in the opinion of such underwriters can be sold without adversely
affecting the marketability of the offering, allocated pro rata on the basis of
the number of shares requested to be included therein by such Persons and
holders of Registrable Securities.

                           (f) RESTRICTIONS ON DEMAND REGISTRATIONS. The
Corporation will not be obligated to effect any Long-Form Registration within
six months after the effective date of a previous Demand Registration or a
previous Piggyback Registration in which Registrable Securities were sold or
could have been sold.

                           (g) SELECTION OF UNDERWRITERS. The Corporation will
have the right to select the investment banker(s) and manager(s), if any, to
administer any Demand Registration, subject to the approval of holders of a
majority of the Registrable Securities included in such Demand Registration
(which approval will not be unreasonably withheld or delayed).

                           (h) DEFERRAL OF REGISTRATION. Notwithstanding the
foregoing, if the Corporation shall furnish to the holders of Registrable
Securities requesting a registration statement pursuant to this Section 2.2, a
certificate signed by the President or Chief Executive Officer of the
Corporation stating that, in the good faith judgment of the Board of Directors
of the Corporation, it would be materially detrimental to the Corporation and
its stockholders generally for such registration statement to be filed (a "Valid
Business Reason"), the Corporation shall have the right to defer such filing for
a period of not more than 90 days after receipt of the request of the holders of
the Registrable Securities seeking the registration. In addition, if a
registration statement has already been filed and the Corporation shall furnish
to the holders of Registrable Securities who requested a registration statement
pursuant to this Section 2.2, a certificate signed by the President or Chief
Executive Officer of the Corporation setting forth a Valid Business Reason, the
Corporation may cause such registration statement to be withdrawn and its
effectiveness terminated or may postpone amending or supplementing such
registration statement for a period of not more than 90 days. The Corporation
may not utilize the right set forth in this subparagraph (h) more than once in
any 12-month period or more than twice during the term of the this Agreement.

                  2.3 Piggyback Registrations.

                           (a) RIGHT TO PIGGYBACK. Whenever the Corporation
proposes to register any of its securities under the Securities Act (other than
pursuant to a Demand Registration, a registration on Form S-8 or Form S-4 or any
successor forms, a registration covering only an employee benefit plan (as
defined in Rule 405 of the Securities Act) or a registration covering only
securities proposed to be issued in exchange for securities or assets of another
corporation) and the registration form to be used may be used for the
registration of Registrable Securities (a "Piggyback Registration"), the
Corporation will give prompt written notice to all holders of

                                      -4-
<PAGE>   5

Registrable Securities and (subject to subparagraphs (b) and (c) below) shall
include in such registration all Registrable Securities with respect to which
the Corporation has received written requests for inclusion therein within 20
days after the day on which the Corporation's notice is deemed delivered as
provided in Section 6.6.

                           (b) PRIORITY ON PRIMARY REGISTRATION. If a Piggyback
Registration is an underwritten primary registration on behalf of the
Corporation, and the managing underwriters advise the Corporation in writing
that in their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in such offering without
adversely affecting the marketability of the offering, the Corporation will
include in such registration only the amount of securities which the managing
underwriters have advised can be sold, and will allocate such amount as follows:
(i) first, to securities the Corporation proposes to sell; (ii) second, to the
extent an amount of additional securities are to be included in the
registration, to the Registrable Securities requested to be included in such
registration and any securities requested to be included therein by other
Persons with contractual registration rights, pro rata on the basis of the
number of shares requested to be included therein by such Persons and holders of
Registrable Securities; and (iii) third, to any other securities requested to be
included in such registration.

                           (c) PRIORITY ON SECONDARY REGISTRATIONS. If a
Piggyback Registration is an underwritten secondary registration on behalf of
holders of the Corporation's securities, and the managing underwriters advise
the Corporation in writing that in their opinion the number of securities
requested to be included in such registration exceeds the number which can be
sold in such offering without adversely affecting the marketability of the
offering, the Corporation will include in such registration only the amount of
securities which the managing underwriters have advised can be sold, and will
allocate such amount as follows: (i) first, to securities held by Persons with
contractual demand registration rights outstanding on the date hereof, if such
Persons have requested such secondary registration; (ii) second, to the
Registrable Securities requested to be included in such registration and any
securities requested to be included therein by other Persons with contractual
piggyback registration rights, pro rata on the basis of the number of shares
requested to be included therein by such Persons and holders of Registrable
Securities; and (iii) third, to any other securities requested to be included in
such registration.

                  2.4 Undertakings of the Corporation. The Corporation agrees:
(i) not to effect any public sale or distribution (including sales pursuant to
Rule 144) of its equity securities, or any securities convertible into or
exchangeable or exercisable for such securities, during the seven days prior to
and during the 90-day period beginning on the effective date of any underwritten
Demand Registration or any underwritten Piggyback Registration (except as part
of such underwritten registration or pursuant to registrations on Form S-8 or
Form S-4 or any successor form, a registration covering only an employee benefit
plan (as defined in Rule 405 of the Securities Act) or a registration covering
only securities proposed to be issued in exchange for securities or assets of
another corporation), unless the underwriters managing the registered public
offering otherwise agree; and (ii) to provide in any agreements entered into
after the date of this Agreement pursuant to which equity securities of the
Corporation are purchased to require

                                      -5-
<PAGE>   6

each holder thereof to agree that at such time as such holder owns at least one
percent (on a fully-diluted basis) of the Common Stock (including any securities
convertible into or exchangeable or exercisable for Common Stock purchased from
the Corporation pursuant to agreements entered into at any time after the date
of this Agreement (other than in a registered public offering)), in connection
with any underwritten Demand Registration or any underwritten Piggyback
Registration, such holder shall not effect any public sale or distribution of
any such shares for the period of time requested by the managing underwriter,
for a period not to exceed 180 days, unless the managing underwriters of the
registered public offering otherwise agree.

                  2.5 Registration Procedures. Whenever the holders of
Registrable Securities have requested that any Registrable Securities be
registered pursuant to this Agreement, the Corporation will use its best efforts
to effect the registration of such Registrable Securities, and pursuant thereto,
the Corporation will, as expeditiously as possible, do all of the following:

                           (a) REGISTRATION STATEMENT. Prepare and file with the
SEC, a registration statement with respect to such Registrable Securities and
use its best efforts to cause such registration statement to become effective
(provided that before filing a registration statement or prospectus or any
amendments or supplements thereto, the Corporation will furnish to the counsel
selected by the holders of a majority of the Registrable Securities covered by
such registration statement copies of all such documents proposed to be filed,
which documents will be subject to the review and comment of such counsel) and
use its best efforts to avoid the issuance of (or if issued, obtain the
withdrawal of) any order suspending the effectiveness of a registration
statement, or the lifting of any suspension of the qualification (or exemption
from qualification) of any of the Registrable Securities for sale in any
jurisdiction as soon as possible;

                           (b) AMENDMENTS & SUPPLEMENTS. Prepare and file with
the SEC such amendments and supplements to such registration statement and the
prospectus used in connection therewith as may be necessary to keep such
registration statement effective until the earlier of the date on which all
securities covered by such registration statement have been sold or six months;

                           (c) FURNISH COPIES. Furnish to each seller of
Registrable Securities such number of copies of such registration statement,
each amendment and supplement thereto, the prospectus included in such
registration statement (including each preliminary prospectus) and such other
documents as such seller may reasonably request in order to facilitate the
disposition of the Registrable Securities covered by such registration
statement;

                           (d) BLUE SKY COMPLIANCE. Use its best efforts to
register or qualify such Registrable Securities under such other securities or
blue sky laws of such United States jurisdictions as any seller reasonably
requests and do any and all other acts and things which may be reasonably
necessary or advisable to enable such seller to consummate the disposition in
such jurisdictions of the Registrable Securities owned by such seller (provided
that the Corporation will not be required to (i) qualify generally to do
business in any jurisdiction where it would not otherwise be required to qualify
for this subparagraph, (ii) subject itself to taxation in any such jurisdiction,
or (iii) consent to general service of process in any such jurisdiction);

                                      -6-
<PAGE>   7

                           (e) NOTIFICATIONS. Notify each seller of Registrable
Securities at any time when a registration statement related thereto is
effective under the Securities Act, of the happening of any event as a result of
which the prospectus included in such registration statement contains an untrue
statement of a material fact or omits any fact necessary to make the statements
therein not misleading, in light of the circumstances then existing, and, at the
request of any such seller, the Corporation will prepare a supplement or
amendment to such prospectus so that, as thereafter delivered to the purchasers
of such Registrable Securities, such prospectus will not contain an untrue
statement of a material fact or omit to state any fact necessary to make the
statements therein not misleading;

                           (f) LISTING. Cause all such Registrable Securities to
be listed on a national securities exchange or on the Nasdaq National Market, if
applicable, on which similar securities issued by the Corporation are then
listed;

                           (g) TRANSFER AGENT; REGISTRAR. Provide a transfer
agent and registrar for all such Registrable Securities not later than the
effective date of such registration statement;

                           (h) UNDERWRITING AGREEMENTS, ETC. In the event of an
underwritten public offering, enter into and perform its obligations under such
customary agreements (including underwriting agreements in customary form) and
take all such other actions as the holders of a majority of the Registrable
Securities being sold or the underwriters, if any, reasonably request in order
to expedite or facilitate the disposition of such Registrable Securities
(including, without limitation, effecting a stock split or a combination of
shares, if the same can be effected without the approval of the Corporation's
stockholders);

                           (i) SUPPLY INFORMATION. Make available for inspection
by any seller of Registrable Securities, underwriter participating in any
disposition pursuant to such registration statement, and any attorney,
accountant or other agent retained by any such seller or underwriter, all
financial and other records, pertinent corporate documents and properties of the
Corporation, and cause the Corporation's officers, directors, employees and
independent accountants to supply all information reasonably requested by any
such seller, underwriter, attorney, accountant or agent in connection with such
registration statement; and

                           (j) OBTAIN COLD COMFORT LETTER. In the event of an
underwritten public offering, obtain a cold comfort letter from the
Corporation's independent public accountants in customary form, and covering
such matters as are customarily given or covered by independent public
accountants in an underwritten public offering of securities, addressed to the
underwriter(s) or the sellers of Registrable Securities.

                  2.6 Registration Expenses.

                           (a) EXPENSES OF DEMAND REGISTRATION. All expenses
other than underwriting discounts and commissions relating to Registrable
Securities incurred in connection with the registration, filings or
qualifications pursuant to Section 2.2 above, including, without limitation, all
registration, filing and qualification fees, printing and accounting fees,
listing fees and expenses, fees and expenses of compliance with securities or
blue sky laws, fees and

                                      -7-
<PAGE>   8

disbursements of counsel for the Corporation, and the reasonable fees and
disbursements of one counsel for the selling holders of Registrable Securities
(not to exceed $25,000) shall be borne by the Corporation; provided, however,
that if (i) the registration request is subsequently withdrawn at any time at
the request of the holders of 50% of the Registrable Securities to be registered
(other than as a result of information concerning the business or financial
condition of the Corporation that is made known to such holders after the date
on which such registration was requested) and (ii) the participant holders bear
all expenses for such withdrawn registration, such registration shall not count
as a Demand Registration under Section 2.2). Underwriting discounts and
commissions relating to Registrable Securities will be borne and paid ratably by
the Corporation and the holders of such Registrable Securities.

                           (b) EXPENSES OF CORPORATION REGISTRATION. The
Corporation shall bear and pay all expenses incurred in connection with any
registration, filing or qualification of Registrable Securities with respect to
the registrations pursuant to Section 2.3 above, including, without limitation,
all registration, filing and qualification fees, printing and accounting fees,
listing fees and expenses, fees and expenses of compliance with securities or
blue sky laws, fees and disbursements of counsel for the Corporation and the
reasonable fees and disbursements of one counsel for the selling holders of
Registrable Securities (not to exceed $25,000). Underwriting discounts and
commissions relating to Registrable Securities will be borne and paid ratably by
the Corporation and the holders of such Registrable Securities.

                  2.7 Indemnification Provisions.

                           (a) INDEMNITY OF HOLDERS OF REGISTRABLE SECURITIES.
The Corporation agrees to indemnify, to the extent permitted by law, each holder
of Registrable Securities, its officers and directors and each Person who
controls such holder (within the meaning of the Securities Act) against all
losses, claims, damages, liabilities and expenses caused by any untrue or
alleged untrue statement of material fact contained in any registration
statement, prospectus or preliminary prospectus or any amendment thereof or
supplement thereto or any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as the same are caused by or contained in any
information furnished in writing to the Corporation or any underwriter by such
holder expressly for use therein or by such holder's failure to deliver to the
Corporation in writing the information and affidavits required by Section 2.7(b)
after the Corporation has furnished such holder with a sufficient number of
copies of the registration statement or prospectus or any amendments or
supplements thereto.

                           (b) DISCLOSURE AND INDEMNIFICATION BY HOLDERS OF
REGISTRABLE SECURITIES. In connection with any registration statement in which a
holder of Registrable Securities is participating, each such holder will furnish
to the Corporation in writing such information and affidavits relating to
disclosure concerning such holder as the Corporation reasonably requests for
inclusion or otherwise use in connection with any such registration statement or
prospectus and, to the extent permitted by law, will indemnify the Corporation,
its directors and officers and each Person who controls the Corporation (within
the meaning of the Securities Act) against any losses, claims, damages,
liabilities and expenses resulting from any

                                      -8-
<PAGE>   9

untrue or alleged untrue statement of material fact contained in the
registration statement, prospectus or preliminary prospectus or any amendment
thereof or supplement thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading, but only to the extent that such untrue statement or omission is
contained in any information or affidavit so furnished in writing by such
holder; provided, however, that the obligation to indemnify will be several, not
joint and several, among such holders; and, provided, further, however, that the
liability of each holder will be in proportion to and limited to the net amount
received by such holder from the sale of Registrable Securities pursuant to such
registration statement.

                           (c) NOTICE AND DEFENSE. Any person entitled to
indemnification hereunder will: (i) give prompt written notice to the
indemnifying party of any claim with respect to which it seeks indemnification;
and (ii) unless in the reasonable opinion of such indemnified party's counsel, a
conflict of interest between such indemnified and indemnifying parties exists
with respect to such claim, permit such indemnifying party to assume the defense
of such claim with counsel reasonably satisfactory to the indemnified party. The
failure to give timely notice will not relieve the receiving party of any
obligation unless such delay unduly prejudices such party's ability to defend
such claim. In any event, the indemnifying party will not be subject to any
liability for any settlement made by the indemnified party without its consent
(but such consent will not be unreasonably withheld). An indemnifying party who
is not entitled to, or elects not to, assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one counsel for all parties
indemnified by such indemnifying party with respect to such claim, unless in the
reasonable judgment of any indemnified party a conflict of interest may exist
between such indemnified party and any other of such indemnified parties with
respect to such claim.

                           (d) CONTINUING AND SURVIVING OBLIGATIONS; RIGHT OF
CONTRIBUTION. The indemnification provided for under this Agreement will remain
in full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director, or controlling person of such
indemnified party and will survive the transfer of securities after the
completion of the offering. If, for any reason, the indemnity provided in this
Section 2.7 is unavailable to hold harmless an indemnified party under
subparagraphs (a) or (b), then each indemnifying party shall contribute to the
amount paid or payable to such indemnified party as a result of any claim in
such proportion as is appropriate to reflect the relative fault of the
indemnifying party, on the one hand, and the indemnified party, on the other
hand, with respect to such offering of securities. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the indemnifying party or the
indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such untrue statement or
omission. If, however, the allocation provided in the second preceding sentence
is not permitted by applicable law, then each indemnifying party shall
contribute to the amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative faults but also
the relative benefits of the indemnifying party and the indemnified party as
well as any other relevant equitable considerations. Notwithstanding anything
herein to the contrary, (i) no Person

                                      -9-
<PAGE>   10

guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation and (ii) no holder of
Registrable Securities shall be required pursuant to this subparagraph (h) to
contribute any amount in excess of the net proceeds received by such holder from
the sale of Registrable Securities in the offering to which the losses, claims,
damages or liabilities of the indemnified parties relate, less the amount of any
indemnification payment made by such holder pursuant to subparagraph (b).

                  2.8 Rule 144 Reporting. With a view to making available the
benefits of certain rules and regulations of the SEC which may at any time
permit the sale of the Registrable Securities to the public without
registration, the Corporation agrees to:

                           (a) make and keep public information available, as
defined for purposes of Rule 144(c) under the Securities Act;

                           (b) file with the SEC in a timely manner all reports
and other documents required of the Corporation to be filed under the Securities
Act and the Securities Exchange Act of 1934, as amended (the "Exchange Act")
(provided it is subject to such reporting requirements); and

                           (c) furnish to any holder of Registrable Securities,
upon request, a written statement by the Corporation as to its compliance with
the reporting requirements of Rule 144 and of the Securities Act and the
Exchange Act (provided it is subject to such reporting requirements), a copy of
the most recent annual or quarterly report of the Corporation, and such other
reports and documents of the Corporation as such holder may reasonable request
to avail itself of any similar rule or regulation of the SEC allowing it to sell
any such securities without registration.

                  2.9 Mergers, Etc. The Corporation shall not, directly or
indirectly, enter into any merger, consolidation, or reorganization in which the
Corporation shall not be the surviving corporation unless the proposed surviving
corporation shall, prior to such merger, consolidation, or reorganization, agree
in writing to assume the obligations of the Corporation under this Agreement,
and for that purpose references hereunder to "Registrable Securities" shall be
deemed to be references to the securities that an Investor would be entitled to
receive in exchange for Registrable Securities under any such merger,
consolidation, or reorganization; provided, however, that the provisions of this
Agreement shall not apply in the event of any merger, consolidation, or
reorganization in which the Corporation is not the surviving corporation if all
Investors holding Registrable Securities are entitled to receive in exchange for
their Registrable Securities consideration consisting solely of (i) cash, (ii)
securities of the acquiring corporation that may be immediately sold to the
public without registration under the Securities Act, or (iii) securities of the
acquiring corporation that the acquiring corporation has agreed to register
within 120 days of completion of the transaction for resale to the public
pursuant to the Securities Act.

                  2.10 Miscellaneous.

                           (a) EFFECTIVE DATE. The rights of the Investors under
this Section 2 are effective as of the date hereof and shall remain in full
force and effect as to any Investor for so long as such Investor continues to
hold any Registrable Securities or securities exercisable for Registrable
Securities.

                           (b) ADJUSTMENTS AFFECTING REGISTRABLE SECURITIES. The
Corporation will not take any action, or permit any change to occur, with
respect to its securities which would materially and adversely affect the
ability of the Investors to include Registrable Securities in a registration
undertaken pursuant to this Agreement or which would materially and adversely
affect the marketability of such Registrable Securities in any such
registration.

                           (c) OTHER REGISTRATION RIGHTS. Except as provided in
this Agreement, the Corporation will not grant to any Person the right to
request the Corporation to register any equity securities of the Corporation, or
any securities convertible or exchangeable into or exercisable for such
securities, without the prior written consent of the holders of a majority of
the Registrable Securities in existence at the time of such consent, except to
the extent such registration rights are not inconsistent with the rights granted
this Agreement.

                           (d) REMEDIES. Any Person having rights under this
Section 2 will be entitled to enforce such rights specifically (without posting
any bond or other security), to recover damages caused by reason of any breach
of any provision of this Section 2, and to exercise all other rights granted by
law; provided that this Section 2.10(d) shall not entitle any Person to
injunctive relief with respect to a registration statement in which such Person
does not participate.

         3. Special Rights of Investors.

                  3.1 Co-Sale Rights.

                           (a) GENERAL. If, at any time, any Stockholder or any
of his permitted successors and assigns or any immediate family members of such
Stockholder (the transferring party or parties are collectively referred to
herein as the "Transferring Party"), proposes to Transfer any or all of his
Capital Stock in the Corporation (or securities convertible into Capital Stock
of the Corporation) to one or more Persons (the "Purchasers"), other than in
connection with a Permitted Transfer (as defined in Section 3.1(d) below) then
the Transferring Party shall provide not less than 20 days notice complying with
Section 3.1(c) below (the "Co-Sale Notice") to each of the Investors.
Thereafter, upon the written request of any of the Investors, the Transferring
Party covenants and agrees to include as part of the Transferring Party's
proposed Transfer, such number of Warrant Shares then held by such Investor as
determined in accordance with Section 3.1(b) below, and each of the Investors
shall be entitled to sell such Warrant Shares, for a price and upon other terms
and conditions that are identical to the proposed price and terms and conditions
under which the Transferring Party proposes to Transfer its Capital Stock.
Notwithstanding any provision to the contrary, at the option of any Investor, an
Investor may Transfer all or any portion of a Warrant in substitution of
transferring Warrant Shares. In such

                                      -11-
<PAGE>   12

event, the Warrant or portion thereof to be Transferred shall be deemed
exercised by the Purchasers upon such Transfer; and, proceeds otherwise payable
to the Investor for such Transfer in an amount equal to the aggregate exercise
price for such Warrant Shares shall be paid to the Corporation. This Section 3.1
shall not be deemed to authorize any Transfer by any Stockholder or any of his
permitted successors and assigns of any of its Capital Stock.

                           (b) DETERMINATION OF SHARE AMOUNT. Each Investor may
sell all or any part of that number of Warrant Shares held by it equal to the
product obtained by multiplying (i) the aggregate number of shares of Capital
Stock the Transferring Party proposes to Transfer, by (ii) a fraction, the
numerator of which is the number of Warrant Shares owned by such Investor on the
date of the Co-Sale Notice (assuming the exercise of all outstanding Warrants)
and the denominator of which is the sum as of the date of the Co-Sale Notice of
(A) the total number of shares of Capital Stock owned by the Transferring Party,
(B) the Warrant Shares of those Investors that have exercised their co-sale
rights under this Section 3.1 with respect to the proposed Transfer, and (C) the
total number of shares of Capital Stock (including all shares issuable upon
conversion or exercise of outstanding securities) owned by all other
stockholders that have exercised their contractual co-sale rights with respect
to the proposed Transfer.

                           (c) NOTICE. The Co-Sale Notice shall set forth (i)
the number of shares of Capital Stock - proposed to be Transferred by the
Transferring Party, (ii) the name and address of the Purchasers, (iii) the
proposed amount and type of consideration payable for the Capital Stock and the
terms and conditions of payment, and (iv) that the Purchasers have been informed
of the co-sale rights provided for in this Section 3.1 and have agreed to
purchase shares of shares of Capital Stock held by the Investors in accordance
with the terms of this Section 3.1. Upon receipt of a Co-Sale Notice, each
Investor may elect to exercise its co-sale rights to sell shares of Capital
Stock to the Purchasers on the terms set forth in the Co-Sale Notice at any time
within twenty (20) days by delivering a written notice of acceptance (the
"Co-Sale Notice of Acceptance") that sets the number of shares of Capital Stock
(up to the maximum amount set forth in Section 3.1(b)) that the Investor wishes
to sell. Upon expiration of the 20-day period, the Transferring Party will use
reasonable efforts to convince the Purchasers to purchase all the Capital Stock
that he and the Investors are interested in selling; provided, that to the
extent that any Purchaser refuses to purchase all of the Capital Stock that the
Investors have indicated on the Co-Sale Notice of Acceptance that they desire to
sell, the Transferring Party shall not sell to such Purchasers any shares of
Capital Stock unless and until, simultaneously with such sale, the Transferring
Party shall purchase such shares of Capital Stock from such Investors in an
amount not less than their right as set forth in Section 3.1(b) and for the same
consideration and on the same terms and conditions as the proposed transfer
described in the Co-Sale Notice.

                           (d) For purposes of this Agreement, a "Permitted
Transfer" shall mean:

                                    (i) Any repurchase of Common Stock by the
Corporation pursuant to a right of repurchase upon the termination of the
transferring Stockholder's employment or consulting relationship with the
Corporation;

                                      -12-
<PAGE>   13

                                    (ii) Any bona fide gift to a charitable
organization;

                                    (iii) Any Transfer to the transferring
Stockholder's Affiliate (including, without limitation, a wholly owned (either
directly or through an unbroken chain of entities each of which is wholly owned)
subsidiary of such Stockholder), ancestor, descendant, sibling or spouse or to a
trust for their benefit or a partnership that is owned entirely by the
transferring Stockholder and/or his ancestors, descendants, siblings or spouse;
and

                                    (iv) Any Transfer pursuant to a valid
registration statement of the Corporation;

                           provided, that in the case of subparagraphs (i) -
(iii) above, that the pledgee, transferee or donee (each a "Permitted
Transferee") shall furnish the Corporation, the Investors and the Stockholders
with a written agreement to be bound by and comply with all provisions of this
Agreement. Any Permitted Transferee of a Stockholder shall be deemed a
"Stockholder" for all purposes of this Agreement. The Investors may Transfer any
of their respective Warrants or Warrant Shares at any time without limitation,
so long as the Transfer is in compliance with applicable securities laws.

                           (e) PROHIBITED TRANSFERS.

                                    (i) In the event any Transferring Party
should Transfer any shares of Capital Stock in contravention of the co-sale
rights of the Investors as set forth in this Section 3.1 (a "Prohibited
Transfer"), to the extent such Transfer is valid and recorded on the books of
and recognized by the Corporation, the Investors, in addition to such other
remedies as may be available at law, in equity or hereunder, shall have the put
option provided below, and such Transferring Party shall be bound by the
applicable provisions of such option.

                                    (ii) In the event of a Prohibited Transfer,
each Investor shall have the right to sell to the Transferring Party the type
and number of shares of Common Stock equal to the number of shares each Investor
would have been entitled to transfer to the Purchasers above had the Prohibited
Transfer been effected pursuant to and in compliance with the terms hereof. Such
sale shall be made on the following terms and conditions:

                                             (1) The price per share at which
the shares are to be sold to the Transferring Party shall be equal to the price
per share paid by the Purchasers to the Transferring Party in the Prohibited
Transfer.

                                             (2) Within 30 days after the later
of the dates on which the Investor (A) received notice of the Prohibited
Transfer or (B) otherwise became aware of the Prohibited Transfer, each Investor
shall, if exercising the option created hereby, deliver to the Transferring
Party the certificate or certificates representing shares to be sold, each
certificate to be properly endorsed for transfer.

                                             (3) The Transferring Party shall,
upon receipt of the certificate or certificates for the shares to be sold by an
Investor pay the aggregate purchase price therefor in cash or by other means
acceptable to the Investor.

                                      -13-
<PAGE>   14

                           (f) CLASS OF STOCK. Notwithstanding the foregoing, if
a proposed Transfer relates to the sale of Capital Stock other than Common
Stock, the Transferring Party shall not Transfer such shares of Capital Stock
unless the Transferring Party shall make provisions satisfactory to the
Investors for the sale to and purchase by the Purchasers of shares of Common
Stock in addition to any shares of such Capital Stock, to enable all Investors
to participate in such Transfer on the basis contemplated by Section 3.1(a), and
each Investor may participate in the proposed Transfer by selling shares of
Warrant Shares.

                  3.2 Put Rights.

                           (a) The Corporation hereby grants to each Investor
the right, at any time after the fifth anniversary of the date hereof if the
Common Stock is not then traded on a securities exchange, the Nasdaq Stock
Market or over-the-counter and there is otherwise no active public market for
the Common Stock, to require the Corporation to repurchase all or any part of
the Warrants or the Warrant Shares then held or issuable to such Investor, in
accordance with the terms of this Section 3.2 for a purchase price equal to the
Fair Market Value per share (as determined in accordance with subparagraph (c)
below) of the Warrants or Warrant Shares then held by such Investor. In the
event that an Investor desires to sell the Warrants or Warrant Shares to the
Corporation, such Investor shall deliver to the Corporation a written notice
(the "Put Notice") specifying the number of Warrant Shares (or Warrant Shares
underlying Warrants in the event that Warrants are to be repurchased) to be
repurchased from such Investor (the "Put Shares"). Within five days after
receipt of a Put Notice, the Corporation shall deliver a copy of the Put Notice
to the other holders of Warrants and Warrant Shares.

                           (b) Within 60 days after the delivery of the Put
Notice, the Corporation will purchase, and the Investors exercising rights under
this Section 3.2 (the "Selling Investors") will sell all or any portion of, the
Warrants or Warrant Shares, as the case may be, at a mutually agreeable time and
place (the "Put Closing"). At the Put Closing, the Selling Investors shall
deliver to the Corporation the Warrants or certificates representing the Warrant
Shares to be repurchased by the Corporation, and the Corporation shall deliver
to the Selling Investors' the Fair Market Value per share by cashier's or
certified check payable to the Selling Investors or by wire transfer of
immediately available funds.

                           (c) The determination of the Fair Market Value of the
Warrants or Warrant Shares, as applicable, shall be based upon the following:

                                    (i) The Fair Market Value shall initially be
determined by an independent appraiser selected by the board of directors of the
Corporation (the "Board Appraiser"), which determination (including a copy of
the Board Appraiser's written appraisal) shall be provided to the Selling
Investors within 30 days of the Put Notice (the "Board Appraisal").

                                    (ii) If the Selling Investors disagree with
the Board Appraisal, such Selling Investors shall notify the Corporation of such
disagreement within ten days of delivery of the Board Appraisal. In the event of
such disagreement, the Selling Investors delivering such a notice, at such the
Selling Investors' own expense shall retain an independent

                                      -14-
<PAGE>   15

appraiser (the "Investors' Appraiser") to perform a second determination of Fair
Market Value (the "Investors' Appraisal"). Upon completion of the Investors'
Appraisal (but in no event later than 45 days after the delivery of the Board
Appraisal), the Selling Investors shall provide a copy of the Investors'
Appraisal to the Corporation. If the Investors' Appraisal differs by less than
10% in value from the Board Appraisal, the Fair Market Value shall be the
arithmetic mean of the Investors' Appraisal and the Board Appraisal.

                                    (iii) If the Investors' Appraisal and the
Board Appraisal differ by 10% or more in value, then the Investors' Appraiser
and Board Appraiser shall jointly select a third independent appraiser to choose
either the Fair Market Value estimate contained in the Board Appraisal or the
Investors' Appraisal, which decision shall be made within 30 days after the
completion of the Investors' Appraisal. The cost of the third independent
appraiser shall be borne equally by the Corporation, on the one hand, and by the
Investors, on the other hand.

                                    (iv) In determining Fair Market Value, the
parties agree that the Board Appraiser, Investors' Appraiser and third
independent appraiser shall be instructed to consider, among standard
assumptions, that the Fair Market Value of the Warrants or Warrant Shares, as
the case may be, shall be determined without any reduction in value for lack of
control or the inherent lack of liquidity of non-public minority interests.

                                    (v) At any time prior to the date that is 15
days following the date that Fair Market Value is finally determined in
accordance with this Section 3.2(d), if applicable, any Selling Investor that
has exercised the put rights granted herein may rescind such exercise upon
written notice to the Corporation; provided that such rescission shall only be
effective if the Selling Investor reimburses the Corporation for all costs and
expenses actually incurred in connection with the Selling Investors' initial
exercise of put rights. Any such rescission shall not affect the right of any
Investor to exercise the put rights granted herein at any time thereafter prior
to expiration of the put rights hereunder.

                  3.3 Right of First Refusal.

                           (a) GENERAL. In the event that the Corporation
intends to consummate an Equity Issuance, the Corporation shall provide each
Investor with a right of first refusal to purchase all or any part of its pro
rata portion of such Equity Issuance, on the terms and conditions offered by the
Corporation. The Investors' pro rata portion is equal to the (i) the number of
Warrant Shares issued or issuable to all of the Investors immediately prior to
such Equity Issuance, divided by (ii) the total number of shares of the
Corporation's Common Stock outstanding immediately prior to such issuance
(assuming the conversion of all outstanding preferred stock of the Corporation
and the exercise of all outstanding options, warrants or similar rights)
(collectively, the "Investors' Pro Rata Share").

                           (b) PROCEDURE. The Corporation shall provide
Investors 20 days prior written notice (the "Offer Notice") of such Equity
Issuance, together with the details and terms of such intended transaction. Each
Investor shall respond to the Corporation within 15 days of receiving the Offer
Notice by notifying the Corporation whether or not it desires to purchase equity
securities in such Equity Issuance, stating the number of such securities such
Investor

                                      -15-
<PAGE>   16

desires to purchase. In the event that the Investors who have elected to
exercise their rights under this Section 3.3 (the "Participating Investors")
elect to purchase in the aggregate more than the Investors' Pro Rata Share (the
"Excess Amount"), the number of shares that may be purchased by each
Participating Investor pursuant to this Section 3.3 shall be reduced by an
amount equal to the product obtained by multiplying the Excess Amount by a
fraction, the numerator of which is the number of Warrant Shares which such
Participating Investor holds immediately prior to such issuance, and the
denominator of which is the total number of Warrant Shares which all of the
Participating Investors hold immediately prior to such issuance (in each case
assuming the exercise of all outstanding Warrants).

                           (c) UNSUBSCRIBED SHARES. In the event that the
Investors fail to exercise in full the right of first refusal within the
applicable time period, then, with respect to the issuance of such unsubscribed
shares, the rights of such Investors under this Section 3.3 shall expire and the
Corporation shall have 120 days thereafter to contract to sell such equity
securities at a price and upon general terms not more favorable to the
purchasers thereof than specified in the Offer Notice. In the event that the
Corporation has not contracted to sell such equity securities within such
120-day period, then the Corporation shall not thereafter issue or sell any such
securities without again first offering them to the Investors pursuant to this
Section 3.3.

                  3.4 Termination. The rights of each of the Investors under
this Section 3 shall become effective as of the date hereof and shall survive
the termination or expiration of the Investment Agreement and the repayment in
full by the Corporation of all amounts owed under the Debentures and all other
monetary Obligations and shall remain in full force and effect until such time
as no Warrants or Warrant Shares are outstanding.

         4. Covenants. Notwithstanding the termination of the Investment
Agreement or the payment of any amounts due under any Loan Documents, unless
Allied shall otherwise consent in writing, the Corporation covenants and agrees
to comply with the following:

                  4.1 Financial Information. The Corporation shall furnish to
each Investor:

                           (a) within 90 days after the end of each fiscal year,

operations, stockholders' equity and cash flows, showing the financial condition
of the Corporation and its Subsidiaries, as of the close of such fiscal year and
the results of its operations during such year, such Consolidated statements to
be audited by an independent public accountant of recognized national or
regional standing reasonably acceptable to Allied and accompanied by an opinion
of such accountant (which shall not be qualified in any material respect) that
such financial statements fairly present the financial condition and results of
operations of the Corporation and its Subsidiaries on a Consolidated basis in
accordance with GAAP;

                           (b) within 30 days after the end of each month, the

for the corresponding month and fiscal year-to-date period of the preceding
fiscal year and the corresponding figures for the corresponding month and fiscal
year-

<PAGE>   17

to-date period of the annual forecast, all certified by its Financial Officer as
fairly presenting in all material respects the financial condition and results
of operations of the Corporation and its Subsidiaries on a Consolidated basis in
accordance with GAAP (but without footnotes), subject to normal year-end audit
adjustments, together with a brief management summary description of operations;

                           (c) at least 15 days prior to the end of each fiscal
year, an annual financial plan and budget of the Corporation and its
Subsidiaries (detailed on a month-to-month basis) for the next succeeding fiscal
year (by major product line) and projections of the Corporation's monthly
financial statements (by major product line) for the next succeeding three
fiscal years, in a form consistent with past practices, which financial plan and
budget shall have been approved by the board of directors of the Corporation;

                           (d) concurrently with delivery to the Investors (as
defined in that certain Amended and Restated Stockholders Agreement dated
October 25, 1999 by and among the Corporation and certain of its stockholders
party thereto (the "Stockholders Agreement")) any documents or other information
delivered to such Investors pursuant to Section 3 of the Stockholders Agreement;
and

                           (e) promptly, from time to time, such other
information (in writing if so requested) regarding the operations, business
affairs and financial condition of the Corporation or any of its Subsidiaries,
as any Investor may reasonably be request or to otherwise enable such Investor
to file any form required by any Governmental Authority.

                  The Investors agree to hold all information received pursuant
to this Agreement in confidence, to the extent required under Section 6.1
hereto.

                  4.2 Existence; Businesses and Properties.

                           (a) The Corporation will do or cause to be done all
things necessary to preserve, renew and keep in full force and effect its legal
existence.

                           (b) The Corporation will do or cause to be done all
things necessary to obtain, preserve, renew, extend and keep in full force and
effect the rights, licenses, permits, franchises, authorizations, patents,

in all jurisdictions in which the Corporation or its Subsidiaries currently
conducts business; comply in all material respects with all applicable laws,
rules, regulations and decrees and orders of any Governmental Authority, whether
now in effect or hereafter enacted; and at all times maintain and preserve all
property material to the conduct of such business and keep such property in good
repair, working order and condition (ordinary wear and tear excepted) and from
time to time make, or cause to be made, all needful and proper repairs,
renewals, additions, improvements and replacements thereto necessary in order
that the business carried on in connection therewith may be properly conducted
at all times.

                  4.3 Maintaining Records; Access to Properties and Inspections.
The Corporation will keep, and will cause its Subsidiaries to keep, proper books
of record and

                                      -17-
<PAGE>   18

account in which full and correct entries (in all material respects) in
conformity with GAAP are made of all dealings and transactions in relation to
its business and activities. The Corporation will permit any representatives
designated by the Investors to visit and inspect the financial records and the
properties of the Corporation and its Subsidiaries at reasonable times during
normal business hours and as often as reasonably requested and to make extracts
from and copies of such financial records, and permit any representatives
designated by the Investors to discuss the affairs, finances and condition of
the Corporation and its Subsidiaries with the officers thereof and independent
accountants therefor; provided, in each such case, that such visit and
inspection can be accomplished without unreasonable disruption to the business
of the Corporation or any Subsidiary. The Investors will provide prior notice to
the Corporation of any planned discussions with its independent accountants and
will permit an officer of the Corporation to be present.

                  4.4 Board Meetings/Observation Rights. So long as Debentures
remain outstanding or Warrant Shares then outstanding or issuable pursuant to
Warrants then outstanding constitute, in the aggregate, more than 5% of the
Corporation's outstanding Capital Stock on an as-converted, fully diluted basis,
the Corporation shall permit one authorized representative of Allied (or any
transferee of Allied with the consent of the Corporation, which consent shall
not be unreasonably withheld) to attend and participate (but not vote) in all
meetings of its board of directors and any committee thereof (other than the
Audit Committee and the Compensation Committee), whether in person, by telephone
or otherwise, and shall provide such representative with such notice and other
information with respect to such meetings as are delivered to the directors of
the Corporation and at the same time.

                  4.5 Reservation of Warrant Shares. So long as any Warrants are
outstanding, the Corporation shall at all times reserve and keep available out
of its authorized but unissued shares of Common Stock, solely for the purpose of
issuance upon the exercise of the Warrants, such number of shares of Common
Stock issuable upon the exercise of all outstanding Warrants. All Warrant Shares
which are so issuable shall, when issued, be duly and validly issued, fully paid
and nonassessable and free from all taxes, Liens and charges (except those based
on the income, revenues or capital gains of the Investors). The Corporation
shall take all such reasonable action as may be necessary to assure that all
such shares of Common Stock may be so issued without violation of any applicable
law or governmental regulation or any requirements of any domestic securities
exchange upon which shares of Common Stock may be listed (except for official
notice of issuance which shall be immediately transmitted by the Corporation
upon issuance).

                  4.6 Replacement of Warrants. So long as any Warrants are
outstanding, the Corporation shall perform all acts required under the Warrants,
including the re-issuance or replacement of Warrants to any of the Investors
upon transfer, exchange, loss or destruction thereof (upon provision of
reasonable indemnification and affidavit).

                  4.7 Amendment of Charter Documents. The Corporation shall not
amend the Corporation's Certificate of Incorporation in a manner that amends,
reclassifies or alters the rights, powers or preferences of the Common Stock,
without the prior written consent of the

                                      -18-
<PAGE>   19

holders of a majority of the Warrant Shares (assuming the conversion of all
outstanding Warrants); provided, that nothing in this Section 4.7 shall be
construed to require any consent for the Corporation to create or issue
preferred stock, without regard to the various terms, rights or preferences
thereof.

                  4.8 Further Assurances. The Corporation will execute, and will
cause its Subsidiaries to execute, any and all further documents, agreements and
instruments, and take all further reasonable action that may be required under
applicable law, or that any Investor may reasonably request, in order to
effectuate the transactions contemplated hereby. The Corporation shall deliver
or cause to be delivered to the Investors all such instruments and documents as
any Investor may reasonably request to evidence compliance with this Section.

                  4.9 Litigation. Within 10 days after the Corporation learns of
the filing or commencement, or receives a written threat of commencement or
filing, of any material litigation or proceeding against the Corporation, or any
of its respective assets, the Corporation will provide the Investors with
written notice of the nature and extent of such litigation or proceeding and,
upon request by the Investors, copies of all pleadings related thereto.

                  4.10 Defaults. Within 10 days after the receipt by the
Corporation of written notice of a default by the Corporation under any material
contract, agreement or document (including loans and leases) to which the
Corporation is a party or by which it is bound, the Corporation will provide the
Investors with written notice of the nature and extent of such default.

                  4.11 Regulatory Filings; Press Releases. Within 10 days after
filing, copies of all reports or other material documents filed by the
Corporation with the SEC pursuant to Section 13 or Section 15(d) of the Exchange
Act, or with any Governmental Authority, including, without limitation, the U.S.
Internal Revenue Service, the U.S. Environmental Protection Agency (or any state
equivalent), the U.S. Occupational Safety Health Administration, shall be
furnished or made available in electronic form to the Investors; and, promptly
upon the request of any Investor, the Corporation shall furnish or make
available in electronic form to such Investor, as the case may be, copies of any
press releases and other documents that the Corporation shall have released to
the press during the preceding 90 days.

                  4.12 Accountant's Reports. Promptly upon becoming available,
the Corporation shall furnish to the Investors copies of all reports prepared
for or delivered to the management of the Corporation by its outside
accountants.

                  4.13 Suspension of Rights; Termination. The obligations of the
Company under this Section 4 shall be suspended and of no effect during any
period in which (i) the Corporation's Common Stock is publicly-traded on a
nationally recognized exchange and (ii) the Warrant Shares then outstanding or
issuable pursuant to Warrants then outstanding constitute, in the aggregate,
less than 5% of the Corporation's outstanding Capital Stock on an as-converted,
fully diluted basis. The provisions of this Section 4 shall terminate at such
time as no Warrants or Warrant Shares are outstanding.

                           FOR NON-EMPLOYEE DIRECTORS
                 (AS AMENDED AND RESTATED THROUGH MAY 17, 2001)

                             BLUE RHINO CORPORATION

                     AMENDED AND RESTATED STOCK OPTION PLAN
                           FOR NON-EMPLOYEE DIRECTORS
                 (AS AMENDED AND RESTATED THROUGH MAY 17, 2001)

         This Amended and Restated Stock Option Plan for Non-Employee Directors
amends and restates in its entirety as of May 17, 2001, that certain Stock
Option Plan for Non-Employee Directors of Blue Rhino Corporation, which was
originally effective on May 18, 1998 and previously amended and restated as of
December 30, 1998.

         SECTION 1. PURPOSE. The purpose of the Stock Option Plan for
Non-Employee Directors (the "Plan") is to attract and retain persons of
exceptional ability to serve as members of the Board of Directors of Blue Rhino
Corporation (the "Company"), and to align the interests of the Company's
non-employee directors with that of the stockholders in enhancing the value of
the Company's capital stock. This purpose will be carried out through the
granting of nonqualified stock options (individually, an "option," and
collectively, "options") to eligible non-employee directors of the Company.

         SECTION 2. ADMINISTRATION.

                  (a) The Plan shall be administered by the Board of Directors
         of the Company (the "Board" or the "Board of Directors"), unless the
         Board delegates all or part of its discretion to administer the Plan to
         the Compensation Committee of the Board or such successor committee of
         the Board that is designated by the Board to administer the Plan
         (collectively, the "Committee"). The Committee shall be comprised of
         such number of "non-employee directors," as such term is defined in
         Rule 16b-3 adopted under the Securities Exchange Act of 1934, as
         amended (the "Exchange Act"), as may be necessary to comply with Rule
         16b-3, unless otherwise determined by the Board. For the purposes
         herein, the Board, and, upon delegation of authority to the Committee,
         the Committee, shall be referred to herein collectively as the
         "Administrator."

                  (b) Any action of the Administrator may be taken by a written
         instrument signed by all of the members of the Board or the Committee,
         as the case may be, and any action so taken by written consent shall be
         as fully effective as if it had been taken by a majority of the members
         at a meeting duly held and called. Subject to the provisions of the
         Plan, the Administrator shall have full and final authority, in its
         discretion, to establish, amend and rescind rules and regulations for
         the administration of the Plan; to construe and interpret the Plan, the
         rules and regulations, and the agreements evidencing options granted
         under the Plan; and to make all other determinations deemed necessary
         or advisable for administering the Plan. Notwithstanding any other
         provision herein, (i) the Administrator also shall have authority, in
         its discretion, to accelerate the date that any option which was not
         otherwise exercisable or vested shall become exercisable or vested in
         whole or in part, and (ii) the Administrator shall also have authority,
         in its discretion, to extend the period during which an option may be
         exercised. To the extent, if any,

<PAGE>   3

         necessary to comply with Rule 16b-3, provisions in Section 6 of the
         Plan relating to the grant of options following the annual meeting of
         stockholders of the Company, and the amount, price and timing of such
         options, shall not be subject to the discretion of the Administrator or
         any other person. No member of the Administrator shall be liable for
         any action or determination made in good faith with respect to the
         Plan. The Administrator may delegate to an officer or officers of the
         Company the authorization to execute and deliver on behalf of the
         Company any document or instrument required to be delivered under this
         Plan.

         SECTION 3. TYPE OF OPTIONS. Options granted pursuant to the Plan shall
be nonstatutory options which are not intended to meet the requirements of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code").

         SECTION 4. ELIGIBILITY. Directors of the Company who, at the time of
grant, are not employees or officers of the Company ("Eligible Directors") shall
be eligible to participate in the Plan. Each Eligible Director to whom options
are granted shall be referred to herein as a "Participant" in the Plan.

         SECTION 5. SHARES AVAILABLE UNDER THE PLAN. Subject to adjustment as
provided in Section 10 below, an aggregate of 400,000 shares of the Company's
Common Stock, par value $0.001 (the "Common Stock"), shall be available for
issuance pursuant to the provisions of the Plan. Such shares may be authorized
and unissued shares or may be shares issued and thereafter acquired by the
Company. If an option granted under the Plan shall expire or terminate for any
reason without having been exercised in whole or in part, the unpurchased shares
subject to such option shall again be available for subsequent option grants
under the Plan.

         SECTION 6. AUTOMATIC GRANT OF OPTIONS.

                  (a) On December 30, 1998 each Eligible Director shall receive
         options to purchase 8,000 shares of Common Stock, and on an annual
         basis thereafter on the first business day after the annual meeting of
         the stockholders of the Company as designated in the notice of annual
         meeting of stockholders, each Eligible Director of the Company shall
         receive options to purchase 4,000 shares of Common Stock. The date of
         grant of an option (the "Grant Date") shall be December 30, 1998 with
         respect to the options granted on that date and the first business day
         after each subsequent annual meeting of the stockholders with respect
         to the options granted on such dates.

                  (b) Notwithstanding the provisions of Section 6(a) herein, in
         the event that a Participant fails to attend four Board meetings
         between the Grant Date and the date of the next annual meeting of the
         stockholders of the Company, the Participant shall forfeit options to
         purchase 1,000 shares for each meeting less than four which the
         Participant attends; provided, however, that in the event the
         Participant fails to attend at least two Board meetings between the
         Grant Date and the date of the next annual meeting, the Participant
         shall forfeit all options granted to him or her on the previous Grant
         Date. Participation by conference telephone or by other
         telecommunications equipment will be

                                       2
<PAGE>   4

         deemed attendance at a Board meeting for the purpose of receiving
         options under this Plan.

         SECTION 7. TERMS AND CONDITIONS OF OPTIONS.

         7.1 Exercise and Term of Options.

                  (a) Each option granted under the Plan shall be exercisable at
         the rate of one-third (1/3) per year commencing on the first
         anniversary of the Grant Date, such that the option shall become
         exercisable in full on the third anniversary of each Grant Date,
         subject to the provisions of Section 7.1(b) and Section 9 hereof.
         Options granted under the Plan shall expire ten years from the date on
         which the option is granted, unless terminated earlier in accordance
         with the Plan.

                  (b) Notwithstanding the provisions of Section 7.1(a) above, an
         option granted to any Participant shall become immediately exercisable
         in full upon the first to occur of:

                           (i) The death of the Participant, in which case the
                  option may be exercised by the Participant's executor or
                  administrator, or if not so exercised, by the legatees or
                  distributees of his or her estate or by such other person or
                  persons to whom the Participant's rights under the option
                  shall pass by will or by the applicable laws of descent and
                  distribution;

                           (ii) Such time as the Participant ceases to be a
                  director of the Company by reason of his or her permanent
                  disability (as determined by the Administrator);

                           (iii) Such time as the Participant ceases to be a
                  director of the Company as a result of retirement from the
                  Board of Directors on or after attaining age 65; or

                           (iv) Such time as a Participant ceases to be eligible
                  to participate in this Plan by reason of his or her becoming
                  an employee of the Company or any of its subsidiaries.

                  (c) In the event a Participant ceases to be a director of the
         Company by reason of death as described in Section 7.1(b)(i), any
         option granted to such Participant hereunder shall expire 90 days from
         the date the Participant ceases to be a director of the Company, but in
         no event later than the day preceding the tenth anniversary of the
         Grant Date of such option.

                  (d) In the event that the Participant ceases to be a director
         of the Company due to disability, retirement or becoming an employee of
         the Company or a subsidiary as described in Sections 7.1(b)(ii) through
         (iv), and after his or her option has become exercisable in whole or in
         part, such option shall remain exercisable in whole or in part, as the
         case may be, in accordance with the terms hereof for a period of 30
         days from the

                                       3
<PAGE>   5

         date the Participant ceases to be a director, but in no event later
         than the day preceding the tenth anniversary of the Grant Date of such
         option.

                  (e) In the event that the services of a Participant as a
         director of the Company terminate for a reason other than due to death,
         disability, retirement or becoming an employee of the Company as
         provided in Section 7.1(b)(i) through (iv) above, then his options
         shall terminate at the time of his termination of service; provided,
         however, that no portion of the option may be exercised later than the
         day preceding the tenth anniversary of the Grant Date of such option.

         7.2 Exercise Price. The exercise price of each share of Common Stock
subject to an option shall be the "Fair Market Value" of a share of Common Stock
on the Grant Date of the option. "Fair Market Value" means the value determined
on the basis of the good faith determination of the Administrator, without
regard to whether the Common Stock is restricted or represents a minority
interest, pursuant to the applicable method described below:

                  (a) If the Common Stock is listed on a national securities
         exchange or quoted on The Nasdaq Stock Market ("NASDAQ"), the "Fair
         Market Value" shall be the closing price per share of the Common Stock
         on the date on which the option is granted or other determination is
         made (each, a "valuation date") or the most recent trading date
         preceding the valuation date for which such information is available,
         as reported by the principal national exchange on which such shares are
         traded (in the case of an exchange) or by the NASDAQ, as the case may
         be;

                  (b) If the Common Stock is not listed on a national securities
         exchange or quoted on the NASDAQ, but is actively traded in the
         over-the-counter market, the "Fair Market Value" shall be the average
         of the closing bid and asked prices for the Common Stock on the
         valuation date, or the most recent trading date preceding the valuation
         date for which such quotations are reported; and

                  (c) If, on the relevant date, the Common Stock is not publicly
         traded or reported as described in Section 7.2(a) or (b) herein, the
         "Fair Market Value" shall be determined in good faith by the
         Administrator.

         7.3 Payment of Exercise Price; Tax Withholding.

                  (a) Subject to the terms and conditions of the Plan, an option
         granted hereunder shall, to the extent then exercisable, be exercisable
         in whole or in part by giving written notice to the Company's Secretary
         stating the number of shares with respect to which the option is being
         exercised, accompanied by payment in full for such shares.

                  (b) An option may be exercised by providing payment (i) in
         cash or check and (ii) if approved by the Administrator, payment in
         full or in part may also be made (A) by delivering Common Stock already
         owned by the Participant having a total Fair Market Value on the date
         of such delivery equal to the Option Price; (B) by authorizing the

                                       4
<PAGE>   6

         Company to retain shares of Common Stock which would otherwise be
         issuable upon exercise of the Option having a total Fair Market Value
         on the date of delivery equal to the Option Price; (C) by the delivery
         of cash by a broker-dealer to whom the Participant has submitted a
         notice of exercise (in accordance with Part 220, Chapter II, Title 12
         of the Code of Federal Regulations, so-called "cashless" exercise); or
         (D) by any combination of the foregoing. No shares of Common Stock will
         be issued until full payment therefor has been made.

                  (c) The Participant shall pay the Company an amount sufficient
         to cover withholding required by law for any federal, state, local or
         foreign taxes, if any, in connection with an exercise of options
         herewith. A Participant may elect in lieu of paying cash to deliver
         shares of Common Stock or direct the Company that shares of Common
         Stock be withheld to satisfy required tax withholding and such shares
         shall be valued at the Fair Market Value as of the exercise date and
         the Administrator shall determine the timing and other terms and
         conditions in which the use of shares of Common Stock to satisfy tax
         withholding may take place.

         7.4 Rights as a Stockholder. No person will have any rights of a
stockholder as to shares of Common Stock subject to an option until, after
proper exercise of the option or other action required, such shares have been
recorded on the Company's official stockholder records as having been issued or
transferred. Upon exercise of the option or any portion thereof, the Company
will have thirty (30) days in which to issue the shares, and the Participant
will not be treated as a stockholder for any purpose whatsoever prior to such
issuance. No adjustment will be made for cash dividends or other rights for
which the record date is prior to the date such shares are recorded as issued or
transferred in the Company's official stockholder records, except as provided
herein or in an option agreement.

         7.5 Documentation of Option Grants. Option grants shall be evidenced by
written instruments prescribed by the Administrator from time to time. The
instruments may be in the form of agreements to be executed by both the
Participant and the president or any vice president of the Company or in the
form of certificates, letters or similar instruments, which need not be executed
by the Participant but acceptance of which will evidence agreement to the terms
of the grant.

         7.6 Nontransferability of Options. Except as otherwise provided in this
Section 7.6, no option granted under the Plan shall be assignable or
transferable by the Participant to whom it is granted, either voluntarily or by
operation of law, except (a) by will or the laws of descent and distribution or
(b) to the extent permitted by the Administrator in a manner consistent with the
registration provisions of the Securities Act of 1933, as amended (the
"Securities Act"), during the lifetime of the Participant, to (i) the spouse or
lineal descendants of the Participant ("Immediate Family Members"), (ii) a trust
or trusts maintained for the exclusive benefit of the Participant and/or such
Immediate Family Members, or (iii) a limited partnership or limited liability
company in which the only partners or members are the Participant and/or such
Immediate Family Members, formed for estate planning purposes; provided, that
(y) the stock option agreement or any amendment thereto executed by the
Administrator pursuant to which such option is granted must expressly provide
for the transferability in a manner consistent with

                                       5
<PAGE>   7

this Section, and (z) subsequent transfers of a transferred option shall be
prohibited (except as otherwise provided in this Section 7.6), and except that
distributions may be made to the Participant and/or such Immediate Family
members from trusts, family limited partnerships or family limited liability
companies described herein). Following a transfer permitted herein, any such
option shall continue to be subject to the same terms and conditions as were
applicable immediately prior to transfer, provided, that for the purposes of
Sections 7.3 and 7.4 of this Plan, the term "Participant" shall be deemed to
refer to the permitted transferee with respect of the options so transferred.
The events contained in Sections 7.1(b), 7.1(c) 7.1(d) and 7.1(e) shall continue
to be applied with respect to the original Participant, and transferred options
shall expire at or after the date the original Participant ceases to be a
director of the Company as provided in Sections 7.1(c), 7.1(d) and 7.1(e) and
shall otherwise be exercisable by the transferee only to the extent and for the
periods specified in Sections 7.1 and 7.3.

         7.7 Approvals. The effectiveness of the Plan and any options granted
hereunder are subject to the approval of the Plan by affirmative vote of a
majority of the shares of the Common Stock present in person or by proxy and
entitled to vote at an annual or special meeting of the stockholders or by
written consent as provided in the Company's charter or by-laws. In the event
that the Plan is not approved by the stockholders, the Plan and any options
granted hereunder shall be void as of no effect.

         The Company's obligation to sell and deliver shares of Common Stock
under the Plan is subject to the approval of any governmental authority required
in connection with the authorization, issuance or sale of the Common Stock.

         SECTION 8. REGULATORY COMPLIANCE AND LISTING. The issuance or delivery
of any shares of stock subject to exercisable options hereunder may be postponed
by the Administrator for such period as may be required to comply with any
applicable requirements under federal securities laws, any applicable listing
requirements of any national securities exchange or similar organization or any
requirements under any law or regulation applicable to the issuance or delivery
of such shares. The Company shall not be obligated to issue or deliver any such
shares if the issuance or delivery thereof would constitute a violation of any
provision of any law or of any regulation of any governmental authority or any
rule of any national securities exchange or similar organization.

         SECTION 9. CHANGE IN CONTROL. Notwithstanding anything to the contrary
in the Plan, the following shall apply to all outstanding options granted under
the Plan:

         9.1 Definitions. The following definitions shall apply to this Section
9:

                  (a) A "Change in Control" shall mean:

                           (i) The acquisition by any individual entity or group
                  (within the meaning of Section 13(d)(3) or 14(d)(2) of the
                  1934 Act) or beneficial ownership (within the meaning of Rule
                  13d-3 promulgated under the 1934 Act) of 50% or more of the
                  combined voting power of the then outstanding voting
                  securities of the Company entitled to vote generally in the
                  election of directors (the

                                       6
<PAGE>   8

                  "Outstanding Voting Securities"); provided, however, that the
                  following acquisitions shall not constitute a Change of
                  Control: (A) any acquisition directly from the Company or any
                  of its subsidiaries, (B) any acquisition by the Company or any
                  of its subsidiaries, (C) any acquisition by any employee
                  benefit plan (or related trust) sponsored or maintained by the
                  Company or any of its subsidiaries, (D) any acquisition by any
                  corporation with respect to which, following such acquisition,
                  more than 50% of, respectively, the then outstanding shares of
                  common stock of such corporation and the combined voting power
                  of the then outstanding voting securities of such corporation
                  entitled to vote generally in the election of directors is
                  then beneficially owned, directly or indirectly, by
                  individuals, entities or groups who were the beneficial
                  owners, respectively, of at least 50% of the Outstanding
                  Voting Securities immediately prior to such acquisition in
                  substantially the same proportions as their ownership,
                  immediately prior to such acquisition, of the Outstanding
                  Voting Securities, or (E) the acquisition by any individual,
                  entity or group which on the date this Plan was adopted by the
                  Board owned 50% or more of the Outstanding Voting Securities.

                           (ii) Approval by the stockholders of the Company of a
                  reorganization, merger or consolidation, in each case, with
                  respect to which all or substantially all of the individuals
                  and entities who were the beneficial owners, respectively, of
                  the Outstanding Voting Securities immediately prior to such
                  reorganization, merger or consolidation do not, following such
                  reorganization, merger or consolidation, beneficially own,
                  directly or indirectly, more than 50% of the combined voting
                  power of the then outstanding voting securities entitled to
                  vote generally in the election of directors, as the case may
                  be, of the corporation resulting from such reorganization,
                  merger or consolidation in substantially the same proportions
                  as their ownership, immediately prior to such reorganization,
                  merger or consolidation, of the Outstanding Voting Securities;
                  or

                           (iii) Approval by the stockholders of the Company of
                  (A) a complete liquidation or dissolution of the Company or
                  (B) the sale or other disposition of all or substantially all
                  of the assets of the Company other than to a corporation, with
                  respect to which following such sale or other disposition,
                  more than 50% of, respectively, the then outstanding shares of
                  common stock of such corporation and the combined voting power
                  for the then outstanding voting securities of such corporation
                  entitled to vote generally in the election of directors is
                  then beneficially owned, directly or indirectly, by all or
                  substantially all of the individuals and entities who were the
                  beneficial owners, respectively, of the Outstanding Voting
                  Securities immediately prior to such sale or other disposition
                  in substantially the same proportion as their ownership,
                  immediately prior to such sale or other disposition, of the
                  Outstanding Voting Securities.

                  (b) "CIC Price" shall mean the higher of (i) the highest price
         paid for a share of Common Stock in the transaction or series of
         transactions pursuant to which a Change in Control of the Company shall
         have occurred, or (ii) the highest reported sales price of

                                       7
<PAGE>   9

         a share of Common Stock during the 60-day period immediately preceding
         the date upon which the event constituting a Change in Control shall
         have occurred.

         9.2 Acceleration of Vesting and Payment of Stock Options.

                  (a) Upon the occurrence of an event constituting a Change in
         Control, all options outstanding on such date shall become 100% vested
         and exercisable and shall be repurchased by the Company by making a
         cash payment to the Participant for such options as soon as may be
         practicable. Upon such payment, such stock options shall be canceled.

                  (b) The amount of cash to be paid to a Participant shall be
         determined by multiplying the number of shares subject to the
         Participant's outstanding options by the difference between the
         exercise price per share and the CIC Price, if higher.

                  (c) Notwithstanding Section 9.2(a) and 9.2(b) herein, if the
         exercise price of options held by a Participant exceeds the CIC Price
         or the Fair Market Value on the date on which the first event
         constituting a Change in Control (as defined in Section 9.1 herein)
         occurs, as the case may be, such option shall be 100% vested and
         exercisable but shall not be canceled.

         SECTION 10. ADJUSTMENT IN EVENT OF CHANGES IN CAPITALIZATION. In the
event of a stock dividend, stock split or combination of shares,
recapitalization or other change in the Company's capitalization, or other
distribution with respect to holders of the Common Stock (other than normal cash
dividends), automatic adjustment shall be made in the number and kind of shares
as to which outstanding options or portions thereof then unexercised shall be
exercisable and in the available shares set forth in Section 5 hereof, to the
end that the proportionate interest of the option holder shall be maintained as
before the occurrence of such event. Such adjustment in outstanding options
shall be made without change in the total price applicable to the unexercised
portion of such options and with a corresponding adjustment in the option price
per share. Automatic adjustment shall also be made in the number and kind of
shares subject to options subsequently granted under the Plan.

         SECTION 11. NO RIGHT TO REELECTION. Nothing in the Plan shall be deemed
to create any obligation on the part of the Board to nominate any non-employee
director for reelection by the Company's stockholders, nor confer upon any
non-employee director the right to remain a member of the Board for any period
of time or at any particular rate of compensation.

         SECTION 12. AMENDMENT AND TERMINATION.

                  (a) The Board may amend, modify or terminate the Plan at any
         time and from time to time; provided, however, that unless required by
         law, no such amendment or modification shall (i) materially adversely
         affect any right or obligation with respect to any outstanding option
         without the consent of the holder of the option, or (ii) unless
         previously approved by the stockholders, increase the number of shares
         of Common

                                       8
<PAGE>   10

         Stock available for grants as provided in Section 5 hereof other than
         an adjustment pursuant to Section 10 hereof. In addition, no such
         amendment shall, unless previously approved by the stockholders (where
         such approval is necessary to satisfy then applicable requirements of
         federal securities laws, the Code or rules of any stock exchange on
         which the Company's Common Stock is listed) (i) in any manner affect
         the eligibility requirements set forth in Section 4 hereof, (ii)
         increase the number of shares of Common Stock subject to any option,
         (iii) change the purchase price of the shares of Common Stock subject
         to any option, (iv) extend the period during which options may be
         granted under the Plan, or (v) materially increase the benefits to
         Participants under the Plan.

                  (b) Unless earlier terminated by the Board of Directors, or
         the shares reserved under the Plan shall have all been committed for
         options granted pursuant to the Plan, the Plan shall terminate on
         December 31, 2008; provided, however, that options which are granted on
         or before this date shall remain exercisable in accordance with their
         respective terms after the termination of the Plan.

         SECTION 13. SUCCESSORS AND ASSIGNS. The Plan shall be binding on all
successors and permitted assigns of a Participant, including but not limited to,
the estate of such Participant and the executor, administrator or trustee of
such estate, the guardian or legal representative of the Participant.

         SECTION 14. GOVERNING LAW. The validity, construction and effect of the
Plan and any action taken or relating to the Plan shall be determined in
accordance with the laws of the State of Delaware, without regard to the
principles of conflicts of laws, and applicable federal law.

         SECTION 15. SECTION 16(B) COMPLIANCE. It is the intention of the
Company that transactions by Eligible Directors under the Plan shall comply with
Rule 16b-3 under the Exchange Act. If any Plan provision is later found not to
be in compliance with Section 16 of the Exchange Act, then, unless the
Administrator shall determine otherwise, the provision shall be deemed null and
void or otherwise construed in such a manner as to enable transactions under the
Plan to meet the requirements of Rule 16b-3 or any successor rule.

         IN WITNESS WHEREOF, this Amended and Restated Stock Option Plan for
