CALL OPTION AGREEMENT

     This Call Option Agreement (the "Agreement") is entered into this 10th day
of April, 1996, by and between THE BEARD COMPANY, an Oklahoma corporation
("Beard"), and Richard R. Dunning, Larry D. Hartzog, and Michael C. Black (with
said individuals being hereafter referred to collectively as the
"Shareholders"). Beard hereby grants to Shareholders an option (the "Option") to
purchase One Hundred Forty-Four Thousand (144,000) shares of the voting common
stock (the "Shares") of Cibola Corporation, a Wyoming corporation ("Cibola"),
which Shares are currently owned by Beard and represent Eighty Percent (80%) of
the issued and outstanding voting common stock of Cibola, at the price and on
the terms set forth herein.

     NOW, THEREFORE, in consideration of the mutual agreements contained herein,
the sum of One Thousand Dollars ($1,000) in cash paid by the Shareholders (in
the aggregate) to Beard, and other good and valuable consideration, the receipt
of which is hereby acknowledged, the parties agree as follows:

     1. Date of Grant; Term of Option. The Option is granted as of April 10,
1996, and it may not be exercised later than June 29, 2006 unless extended by
the mutual agreement of Beard and Shareholders.

     2. Option Exercise Price. Shareholders may exercise the Option by paying to
Beard the following amounts: (i) an amount equal to the greater of (A) the
then-outstanding balance of principal and accrued interest on that certain
Nonrecourse Secured Promissory Note, dated April 10, 1996, and payable by Beard
to Cibola (the "Note") or (B) the then fair market value of the Shares,
determined with reference to the amount to which the holder of the Shares would
be entitled in the event Cibola was liquidated on the effective date of the
exercise of the Option, taking into account all amounts necessary to pay all
debts of Cibola and make all required liquidating distributions to preferred
shareholders of Cibola; and (ii) all amounts owed by Cibola to Beard on any
other agreements between the parties hereto, to the extent such amounts are due
and payable within six months after the Option exercise date.

     3. Exercise of Option. The Option shall be exercisable during its term only
in accordance with the provisions of this Agreement, as follows:

          (a) Right to Exercise. Shareholders shall be entitled to exercise the
     Option provided herein upon the occurrence of any one or more of the
     following:

               (i) If Beard ceases to file consolidated income tax returns for
          federal income tax purposes, or if Beard notifies Cibola of its intent
          to either cease filing such consolidated returns or voluntarily take
          any action which would preclude the filing of such consolidated
          returns; notwithstanding any other provision of this Agreement, or any
          other agreement between the parties hereto, Beard hereby agrees to
          notify Cibola of its intent to cease filing, or to take any action
          that would cause Beard to cease qualifying to file, consolidated
          federal income tax returns on or before that date which is six (6)
          months prior to the last day of the final consolidated return year of
          Beard that includes the results of Cibola's operations;

               (ii) If a Change of Control occurs with regard to Beard; for this
          purpose, "Change of Control" shall mean (A) the acquisition, in one or
          more transactions, by any "person" (as that term is used for purposes
          of Sections 13(d) or 14(d) of the Securities Exchange Act of 1934, as
          amended) of the beneficial ownership of 50% or more of the combined
          voting power of Beard's then-outstanding voting securities, or (B)
          approval by shareholders of Beard of a merger, reorganization or
          consolidation involving Beard if the shareholders of Beard immediately
          before such merger, reorganization or consolidation do not or will not
          directly or indirectly, immediately following such merger,
          reorganization or consolidation, own more than 50% of the combined
          voting power of the outstanding voting securities of Beard resulting
          from or surviving such merger, reorganization or consolidation, or (C)
          approval by shareholders of Beard of a complete liquidation or
          dissolution of Beard, or (D) approval by shareholders of Beard of an
          agreement for the sale or other disposition of all or substantially
          all of the assets of Beard, or (E) acceptance by shareholders of Beard
          of shares in a reorganization or share exchange pursuant to which
          shareholders of Beard immediately before such transaction do not or
          will not, directly or indirectly, immediately following such
          transaction own more than 50% of the combined voting power of the
          outstanding voting securities of Beard resulting from or surviving
          such transaction; or

               (iii) If, regardless of whether any of the above-described events
          have occurred or circumstances exist, Shareholders provide Beard five
          (5) business days' notice of their intent to exercise the Option
          provided for herein.

          (b) Method of Exercise. The Option shall be exercisable by written
     notice, given at least five (5) business days prior to the effective date
     of exercise, which shall recite Shareholders' election to exercise the
     Option for all of the Shares covered hereby, and shall provide a
     representation and agreement by Shareholders as to their investment intent
     with respect to the Shares to be purchased pursuant to this Agreement. Such
     written notice shall be signed by all of the Shareholders, or by persons
     authorized to act on their behalf, and shall be given to Beard in the
     manner provided for herein. The written notice shall be accompanied by
     payment, or arrangements for payment satisfactory to Beard, of the purchase
     price provided for herein. The certificates for the Shares as to which the
     Option is exercised shall be registered in the name of the Shareholders in
     accordance with their respective ownership thereof and shall be legended if
     and as required under applicable law.

          (c) Restrictions on Exercise. The Option may not be exercised if the
     transfer of the Shares upon such exercise would constitute a violation of
     any applicable federal or state securities laws or other laws or
     regulations. As a condition to the exercise of the Option, Beard may
     require Shareholders to make any reasonable representation and warranty
     which is required by applicable law.

     4. Investment Representations. Unless the Shares have been registered under
the Securities Act of 1933, in connection with the acquisition of the Option,
Shareholders represent and warrant as follows:

          (a) Shareholders are acquiring the Option, and upon exercise of the
     Option, they will be acquiring the Shares, for investment for their own
     account, not as a nominee or agent, and not with a view toward, or for
     resale in connection with, any redistribution thereof.

          (b) Shareholders have preexisting business relationships and
     sufficient business experience to allow Shareholders to be reasonably
     assumed to have the capacity to protect their interests in connection with
     the acquisition of the Option and the Shares.

     5. Assignment of Option. The Option may be assigned by Shareholders without
the prior consent or knowledge of Beard.

     6. Rights as a Shareholder. Shareholders shall have no rights as owners of
the Shares, and shall not have the right to vote or receive dividends or other
remuneration with regard to the Shares subject to the Option, until the Option
has been exercised.

     7. No Obligation to Exercise Option. The granting of the Option shall
impose no obligation upon Shareholders to exercise such Option. No failure of
Shareholders to exercise the Option upon the occurrence of any event described
in Section 3(a) shall be deemed to constitute a waiver of Shareholders' right to
exercise the Option at any time thereafter during the term of this Agreement.

     8. Indemnification. In the event Shareholders exercise the Option, they
shall either (i) jointly and severally guarantee the prompt and full payment of
all obligations of Cibola under that certain Tax Sharing Agreement among Beard,
Cibola and Shareholders of even date herewith or (ii) provide collateral
security reasonably acceptable to Beard.

     9. Notices. Any notice given to a party hereto shall be addressed to such
party at the address or facsimile number below, or at such other address as such
party may hereafter designate in writing to the other party hereto. Such notices
may be given personally, by first-class or certified mail (postage prepaid), or

                    CONVERTIBLE SUBORDINATED PROMISSORY NOTE

$_________________                                  _________________, 2005

FOR VALUE RECEIVED, the undersigned, THE BEARD COMPANY, an Oklahoma corporation
(the "Company"), promises to pay to the order of __________________ (the payee,
its successors and permitted assigns are hereinafter called the "Holder"), at
Suite 320, 5600 North May Avenue, Oklahoma City, Oklahoma 73112, or at such
other place as may be designated in writing by the Holder, the principal sum of
_____________ DOLLARS ($______________), together with interest thereon pursuant
to the terms stated below:

RECITAL:

A. This Note is a statement of the rights of the Holder and the conditions to
which the Note is subject and the Holder, by acceptance hereof, agrees as set
forth below.

B. This Note is part of a series of Notes issued in connection with a private
offering (the "Private Placement Offering") made by the Company pursuant to a
Private Placement Memorandum dated June 29, 2005.

                              1. Terms of the Note

     1.1  Payment of Principal and Interest.

     (a) Prior to Default the unpaid principal balance of this Note will bear
interest at the per annum rate equal to twelve percent (12%). Interest will be
paid semi-annually on February 28th and August 31st of each year, commencing on
February 28, 2006, until this Note is paid in full. All interest will be
computed on the basis of a 360-day year of 12 months of 30 days.

     (b) At the time of the issuance of this Note, the Holder may elect in the
subscription agreement entered into between Holder and the Company subscribing
to the Note (the "Subscription Agreement") to have the interest paid either (i)
in cash, or (ii) in shares of the Company's Common Stock (defined below).
Holder's election in the Subscription Agreement regarding the form of interest
payment is irrevocable once made; provided, however, that the Company reserves
the right to pay the interest on the Notes in cash, notwithstanding a Note
holder's election to receive their interest in Common Stock, if, in the opinion
of the Company the issuance of such Common Stock could result in a violation of
federal or state securities laws or any other applicable laws.

     If Holder elects to receive interest payments in the form of Common Stock,
the number of shares Holder will receive, as of each interest payment date will
be determined by dividing the applicable interest payment by the weighted
average closing price of the Company's Common Stock during the 20 trading days
preceding the interest payment date multiplied by 85%. No fractional shares of
Common Stock shall be issued as payment of interest on the Note. If any
fractional share of Common Stock would be issuable upon an interest payment, the
Company shall make an adjustment thereof in cash at the current market value
thereof. For these purposes, the current market value of a share of Common Stock
shall be the closing price on the first business day immediately preceding the
day on which the interest payment was due.

     (c) The entire unpaid principal balance of this Note plus all accrued and
unpaid interest thereon will be due and payable on the Maturity Date.

     1.2 Maturity Date. As used in this Note, "Maturity Date" means the earlier
of: (a) the date the Holder notifies the Company that the unpaid principal
balance of this Note is due based on the occurrence of an Event of Default
(defined below); or (b) August 31, 2009.

     1.3 Allocation of Payments. All payments on this Note will be applied first
to the payment of accrued interest and the balance will be applied in reduction
of the principal balance hereof.

     1.4 Payments. If any payment under this Note becomes due and payable on a
day other than a business day, the maturity thereof will be extended to the next
succeeding business day and such extension of time will in such case be included
in the computation of payments of interest.

     1.5 Expenses. The Company agrees that if, and as often as, this Note is
placed in the hands of an attorney for collection or to defend or enforce any of
the Holder's rights hereunder or under any instrument securing payment of this
Note, the Company will pay the Holder's reasonable attorneys' fees, all court
costs and all other expenses incurred by the Holder in connection therewith.

     1.6 Default Interest. Any sum not paid when due, by acceleration or
otherwise, will bear interest at the per annum rate equal to twelve percent
(14%) (the "Default Interest") and all the Default Interest shall be paid at the
time of and as a condition precedent to curing any Event of Default hereunder.

     1.7 Events of Default. Events of Default include: (a) default for 30 days
in payment when due of the principal on the Notes; (b) default for 30 days in
the payment when due of interest on the Notes; or (c) default in the performance
of Section 2.9 of this Agreement.

                           2. Conversion of the Note

     2.1 Conversion Agent. The Company shall initially serve as its own
conversion agent. The Company may appoint another Conversion Agent at any time.

     2.2 Conversion Privilege. At any time following the date of original
issuance of this Note and prior to the close of business on the business day
immediately preceding August 31, 2009, the Holder of this Note may convert such
Note or any portion thereof into shares of the Company's common stock (the
"Common Stock") (the shares of Common Stock issuable upon such conversion along
with the shares of Common Stock paid as interest on the Note pursuant to Section
1.1(b) of this Note are referred to herein collectively as the "Conversion
Shares"), at the Conversion Price then in effect. The number of shares of Common
Stock issuable upon conversion of this Note shall be determined by dividing the
principal amount of the Note or portion thereof surrendered for conversion by
the Conversion Price in effect on the conversion date. The initial conversion
price of the Note shall be $_____ per share (the "Conversion Price") and is
subject to adjustment as provided in Section 2.7.

     Upon conversion of only a portion of the principal balance of the Notes
surrendered for conversion, the Company shall issue and deliver upon the written
order of the Holder, at the expense of the Company, a new Note for any remaining
unpaid principal balance so surrendered as well as a certificate or certificates
for the number of shares of Common Stock to which such Holder is entitled, as
provided below. The Holder is not entitled to any rights of a holder of Common
Stock until such Holder has converted this Note into Common Stock.

     2.3 Conversion Procedure. To convert this Note, the Holder must (i)
complete and manually sign the Conversion Notice, a form of which is attached
hereto as Exhibit A and deliver it to the Company (ii) surrender the Note to the
Company, (iii) furnish appropriate endorsements and transfer documents to the
Company and (iv) pay any transfer or other tax, if required. The date on which
the Holder satisfies all of the foregoing requirements is the conversion date.
As soon as practicable after the conversion date, the Company shall deliver to
the Holder through its transfer agent a certificate for the number of whole
shares of Common Stock issuable upon the conversion.

     No fractional shares of Common shall be issued upon conversion of the Note.
If more than one Note shall be surrendered for conversion at one time by the
same holder, the number of full shares which shall be issuable upon conversion
shall be computed on the basis of the aggregate principal amount of the Notes
(or specified portions thereof to the extent permitted hereby) so surrendered.
If any fractional share of Common Stock would be issuable upon the conversion of
any Note or Notes, the Company shall make an adjustment thereof in cash at the
current market value thereof. For these purposes, the current market value of a
share of Common Stock shall be the closing price on the first business day
immediately preceding the day on which the Note or Notes are deemed to have been
converted.

     The person in whose name the certificate is registered shall be deemed to
be a stockholder of record on the conversion date; provided, however, that no
surrender of this Note on any date when the stock transfer books of the Company
shall be closed shall be effective to constitute the person or persons entitled
to receive the shares of Common Stock upon such conversion as the record holder
or holders of such shares of Common Stock on such date, but such surrender shall
be effective to constitute the person or persons entitled to receive such shares
of Common Stock as the record holder or holders thereof for all purposes at the
close of business on the next succeeding day on which such stock transfer books
are open; provided, further, that such conversion shall be at the Conversion
Price in effect on the date that this Note shall have been surrendered for
conversion, as if the stock transfer books of the Company had not been closed.
Upon conversion of this Note, Holder shall no longer be a Holder of this Note.

     No payment or adjustment will be made for accrued interest on a converted
Note or for dividends or distributions on shares of Common Stock issued upon
conversion of a Note, but if any Holder surrenders this Note for conversion
between the record date for the payment of an installment of interest and the
next interest payment date, then, notwithstanding such conversion, the interest
payable on such interest payment date shall be paid to the Holder on such record
date.

     If the Holder converts more than one Note at the same time, the number of
shares of Common Stock issuable upon the conversion shall be based on the
aggregate principal amount of Notes converted.

     2.4 Forced Conversion. At any time after February 28, 2007, if the weighted
average closing price of the Company's common stock has been more than two times
the Conversion Price for sixty (60) consecutive trading days, the Company may
give the Note holders written notice that they must convert their Notes within
thirty (30) days after the date of such notice or that the Notes will terminate
and become void as of 5:00 p.m., New York time on the thirty-first (31st) day
(the "Forced Conversion Date") after the date of such notice.

     Upon such Forced Conversion, the person or persons entitled to receive the
shares of Common Stock issuable upon such conversion will be treated for all
purposes as the record holder or holders of such Common Stock on the Forced
Conversion Date whether or not such holder or holders shall have surrendered
their Notes to the Company. Upon the Forced Conversion Date, the principal
balance of the Notes shall be deemed paid and all interest on the Notes shall
cease to accrue. As soon as practicable after the surrender in accordance with
the procedures set forth in Section 2.3, the Company shall then issue and
deliver, at the office of the Company to such holder a certificate or
certificates for the number of shares of Common Stock to which such holder shall
be entitled.

     2.5 Taxes on Conversion. If the Holder converts a Note, he shall pay any
documentary, stamp or similar issue or transfer tax due on the issue of shares
of Common Stock upon such conversion. The Company may refuse to deliver the
certificates representing the Common Stock being issued in a name other than the
Holder's name until the Company receives a sum sufficient to pay any tax which
will be due because the shares are to be issued in a name other than the
Holder's name. Nothing herein shall preclude any tax withholding required by law
or regulations.

     2.6 Company To Provide Stock. The Company shall reserve out of its
authorized but unissued Common Stock a sufficient number of shares of Common
Stock to permit the conversion of all outstanding Notes for shares of Common
Stock. The shares of Common Stock or other securities issued upon conversion of
this Notes shall bear the following legend:

          THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER ANY FEDERAL OR STATE
          SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR
          OTHERWISE DISPOSED OF ABSENT REGISTRATION UNDER THE SECURITIES ACT OF
          1933 AND ANY APPLICABLE STATE SECURITIES LAWS UNLESS AND UNTIL THE
          HOLDER HEREOF PROVIDES (i) INFORMATION REASONABLY NECESSARY TO CONFIRM
          THAT SUCH REGISTRATION IS NOT REQUIRED OR (ii) AN OPINION OF COUNSEL
          TO THE EFFECT THAT SUCH REGISTRATION IS NOT REQUIRED.

     The Company covenants that all shares of Common Stock delivered upon
conversion of the Notes, shall be duly authorized, validly issued, fully paid
and non-assessable and shall be free from preemptive rights and free of any lien
or adverse claim.

     2.7 Adjustment of Conversion Price. The Conversion Price shall be that
price set forth in Section 2.2 of this Note and shall be adjusted from time to
time by the Company in the event the Company shall (i) pay a dividend or other
distribution in shares of Common Stock to holders of Common Stock, (ii)
subdivide its outstanding Common Stock into a greater number of shares, (iii)
combine its outstanding Common Stock into a smaller number of shares or (iv)
reclassify its outstanding Common Stock, the Conversion Price in effect
immediately prior thereto shall be adjusted so that the Holder of any Note
thereafter surrendered for conversion shall be entitled to receive the number of
shares of Common Stock which it would have owned or have been entitled to
receive had such Note been converted immediately prior to the happening of such
event. An adjustment made pursuant to this Section 2.7 shall become effective
immediately after the record date in the case of a dividend or distribution and
shall become effective immediately after the effective date in the case of
subdivision, combination or reclassification.

     2.8 Notice of Adjustment. Whenever the Conversion Price is adjusted the
Company shall promptly mail to the Holder a notice of the adjustment briefly
stating the facts requiring the adjustment and the manner of computing it.

     2.9 Notice of Certain Transactions. In case:

     (a) the Company shall declare a dividend (or any other distribution) on its
Common Stock (other than in cash out of retained earnings); or

     (b) of any reclassification of the Common Stock of the Company (other than
a subdivision or combination of its outstanding Common Stock, or a change in par
value, or from par value to no par value, or from no par value to par value), or
of any consolidation or merger to which the Company is a party and for which
approval of any stockholders of the Company is required, or of the sale or
transfer of all or substantially all of the assets of the Company; or

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

the Company shall cause to be mailed to each the Holder at its address appearing
below or such other address as specified by the Holder, as promptly as possible
but in any event at least ten days prior to the applicable date hereinafter
specified, a notice stating (i) the date on which a record is to be taken for
the purpose of a dividend, or, if a record is not to be taken, the date as of
which the holders of Common Stock of record to be entitled to such dividend is
to be determined, or (ii) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is
expected to become effective or occur, and the date as of which it is expected
that holders of Common Stock of record shall be entitled to exchange their
Common Stock for securities or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up. Failure to give such notice, or any defect therein,
shall not affect the legality or validity of such dividend, distribution,
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up.

     2.10 Effect of Reclassification, Consolidation, Merger or Sale on
Conversion Privilege. If any of the following shall occur, namely: (i) any
reclassification or change of outstanding shares of Common Stock (other than a
change in par value, or from par value to no par value, or from no par value to
par value, or as a result of a subdivision or combination); (ii) any
consolidation, combination or merger to which the Company is a party other than
a merger in which the Company is the continuing corporation and which does not
result in any reclassification of, or change (other than a change in name, or
par value, or from par value to no par value, or from no par value to par value,
or as a result of a subdivision or combination) in, outstanding shares of Common
Stock; or (iii) any sale or conveyance of all or substantially all of the assets
of the Company ("Asset Sale"), then lawful provision shall be made so that the
Holder shall thereafter be entitled to receive upon conversion of the Note, at a
per share valuation equal to the Conversion Price then in effect, the number of
shares of stock or other securities or property of the successor Company
resulting from such reclassification, consolidation, combination, merger, or
Asset Sale that the Holder of the would have been entitled to receive in such
reclassification, consolidation, combination, merger, or Asset Sale if the Note
had been converted immediately before such reclassification, consolidation,
combination, merger, or Asset Sale, all subject to further adjustment as
provided herein. The foregoing provisions of this Section 2.10 shall similarly
apply to successive reorganizations, consolidations, mergers, sales and
transfers and to the stock or securities of any other Company that are at the
time receivable upon the conversion of the Notes.

                          3. Subordination of the Note

     3.1 Note Subordinate to Senior Indebtedness. The Company covenants and
agrees, and the Holder, by its acceptance thereof, likewise covenants and
agrees, that, to the extent and in the manner hereinafter set forth, the payment
of the principal of and interest on this Note is hereby expressly made
subordinate and subject in right of payment to the prior payment in full of all
Senior Indebtedness (as such term is defined in Section 3.3); provided, that so
long as there is no default on the Senior Indebtedness and the payment would not
result in a default thereunder, this Note may be paid in accordance with its
terms when due. The provisions of this Section 3.1 are made for the benefit of
the holders of Senior Indebtedness and such holders are made obligees hereunder
and any one or more of them may enforce such provisions. Holders of Senior
Indebtedness need not prove reliance on the subordination provisions hereof.

     3.2 Default on Senior Indebtedness. In the event and during the
continuation of any default in the payment of principal, premium, interest or
any other payment due on any Senior Indebtedness, or in the event that any event
of default with respect to any Senior Indebtedness shall have occurred and be
continuing and shall have resulted in such Senior Indebtedness becoming or being
declared due and payable prior to the date on which it would otherwise have
become due and payable (unless and until such event of default shall have been
cured or waived or shall have ceased to exist and such acceleration shall have
been rescinded or annulled) or in the event any judicial proceeding such event
of default, then no payment shall be made by the Company with respect to the
principal of, or interest on, this Note; provided, however, nothing in this
Section shall prohibit the Holder from accelerating the Obligations due under
this Note. In the event that, notwithstanding the foregoing, any payment shall
be received by the Holder when such payment is prohibited by this Section 3.2,
such payment shall be held in trust for the benefit of, and shall be paid over
or delivered to, the holders of Senior Indebtedness or their respective
representatives, or to the trustee or trustees under any indenture pursuant to
which any of such Senior Indebtedness may have been issued, as their respective
interests may appear, but only to the extent that the holders of the Senior
Indebtedness (or their representative or representatives or a trustee) notify
the Holder within 30 days of such payment of the amounts then due and owing on
the Senior Indebtedness and only the amounts specified in such notice to the
Holder shall be paid to the holders of Senior Indebtedness; provided, however,
that holders of Senior Indebtedness shall not be entitled to receive payment of
any such amounts to the extent that such holders would be required by the
subordination provisions of such Senior Indebtedness to pay such amounts over to
the obligees on trade accounts payable or other liabilities arising in the
ordinary course of the Company's business.

     3.3 Definition of Senior Indebtedness. "Senior Indebtedness" means, unless
expressly subordinated to or made on a parity with the amounts due under this
Note, the principal of (and premium, if any), unpaid interest on, penalties,
amounts reimbursable, fees, expenses, costs of enforcement and any other amounts
due in connection with (i) indebtedness of the Company, or with respect to which
the Company is a guarantor, to banks, commercial finance lenders, insurance
companies, leasing or equipment financing institutions or other lending
institutions regularly engaged in the business of lending money (excluding
venture capital, investment banking or similar institutions which sometimes
engage in lending activities but which are primarily engaged in investments in
equity securities), which is for money borrowed, or purchase or leasing of
equipment in the case of lease or other equipment financing, whether or not
secured, and (ii) any such indebtedness or any debentures, notes or other
evidence of indebtedness issued in exchange for such Senior Indebtedness, or any
indebtedness arising from the satisfaction of such Senior Indebtedness by a
guarantor.

                        4. Piggyback Registration Rights

     4.1 Participation. Subject to Section 4.2 and 4.3 hereof, if at any time
after the date hereof the Company proposes to file a Registration Statement
(other than a registration on Form S-4 or S-8 or any successor form to such
Forms or any registration of securities as it relates to an offering and sale to
management of the Company pursuant to any employee stock plan or other employee
benefit plan arrangement) with respect to an offering that includes any shares
of Common Stock, then the Company shall give notice of the proposed filing (the
"Piggyback Notice") to all holders of Conversion Shares issued pursuant to
Section 2.2 or Section 2.4 of this Note (the "Registerable Security Holders") as
promptly as practicable (but in no event less than fifteen (15) days before the
anticipated filing date). The Piggyback Notice shall offer the Registerable
Security Holders the opportunity to register such number of Conversion Shares as
the Registerable Security Holders may request and shall set forth (i) the
anticipated filing date of such Registration Statement and (ii) the number of
shares of Common Stock that is proposed to be included in such Registration
Statement. The Company shall include in such Registration Statement such shares
of Conversion Shares for which it has received written requests to register such
shares within ten (10) days after the Piggyback Notice has been given.

     4.2 Underwriter's Cutback. Notwithstanding the foregoing, if a Registration
pursuant to this Article 4 involves an underwritten offering ("Underwritten
Offering") and the managing underwriter or underwriters of such proposed
underwritten offering delivers an opinion to the Registerable Security Holders
that the total or kind of securities which such Registerable Security Holders
and any other persons or entities intend to include in such offering are
reasonably likely to significantly adversely affect the price, timing or
distribution of the securities offered in such offering, then the Company shall
include in such Registration:

     (a) If such Registration was a primary registration by the Company of its
securities, the Company will include in such Registration to the extent of the
number of securities which the managing underwriter advises can be sold in such
Underwritten Offering: first, the securities proposed by the Company to be sold
for its own account; second, any Conversion Shares requested to be included in
such Registration by the Registerable Security Holders, pro rata on the basis of
the number of securities sought to be sold by the requesting Registerable
Security Holders; and third, other securities of the Company proposed to be
included in such Registration, allocated among the Company and the holders
thereof in accordance with the priorities then existing among the Company and
such holders.

     (b) If such Registration was requested other than by the Registerable
Security Holders or the Company, the Company will include in such Registration
to the extent of the number of securities which the managing underwriter advises
can be sold in such Underwritten Offering: first, the securities proposed to be
sold by the security holder initiating the Registration; second, any Conversion
Shares requested to be included in such Registration, pro rata on the basis of
the number of securities sought to be sold by the requesting Registerable
Security Holders; third, any securities of the Company proposed by any other
Persons to be included in such Registration, pro rata on the basis of the number
of securities proposed to be sold by the requesting Persons; and fourth the
securities proposed by the Company to be sold for its own account.

     4.3 Limitation on Participation. Holders of Conversion Shares that are able
to sell 100% of their Conversion Shares without registration under Rule 144 of
the Securities Act of 1933, as amended, within a period of three consecutive
months are not entitled to any Piggyback Registration Rights under this Article
4.

     4.4 Expenses. The Company will pay all Registration Expenses in connection
with each registration of Conversion Shares requested pursuant to this Article
4.

     4.5 Company Control. The Company may decline to file a Registration
Statement after giving the Piggyback Notice, or withdraw a Registration
Statement after filing and after such Piggyback Notice, but prior to the
effectiveness of the Registration Statement, provided that the Company shall
promptly notify each Registerable Security Holder in writing of any such action
and provided further that the Company shall bear all reasonable expenses
incurred by such Registerable Security Holder or otherwise in connection with
such withdrawn Registration Statement.

                                5. Miscellaneous

to the Company or, in the case of mutilation, on surrender and cancellation of

the other Notes issued by the Company in the Private Placement Offering. In the
event the Holder receives payments in excess of its pro rata share of Company's
payments to the holders of all of the Notes, then the Holder shall hold in trust
all such excess payments for the benefit of the holders of the other Notes and
shall pay such amounts held in trust to such other holders upon demand by such
holders.

     5.4 Payment. All payments under this Note shall be made in lawful tender of
the United States.

     5.5 Usury. In the event any interest is paid on this Note which is deemed
