Agent, at the rate of interest equal to either (i) in the case of such Lender,

Administrative Agent in accordance with banking industry rules on interbank
compensation or (ii) in the case of the Borrower, the Applicable Rate. If such
Lender pays such amount to the Administrative Agent, then such amount shall
constitute such Lender's Loan included in such Borrowing.

described in Section 2.02(b) shall be in amounts of at least $100,000 or the

15 and February 15 of each year that this Agreement is in effect and on the
Credit Agreement Termination Date.

            (d) Exit Fee. In addition to other fees in this Section 2.04, the
Borrower shall pay to the Administrative Agent an exit fee equal to five percent
(5.00%) of the total amount of the Bridge Loans that were committed under this
Agreement on the earlier to occur of (i) the date on which Borrower has repaid
all of the Bridge Loans in full or (ii) the Bridge Loan Termination Date.

      Section 2.05 Notes. The Loans made by each Lender shall be evidenced by a
single promissory note of the Borrower in substantially the form of Exhibit A,
dated, in the case of (a) any Lender party hereto as of the date of this
Agreement, the date of this Agreement or (b) any Lender that becomes a party
hereto pursuant to an Assignment and Assumption, as of the effective date of the
Assignment and Assumption, payable to the order of such Lender in a principal
amount equal to its Commitment as in effect on such date, and otherwise duly
completed. The date, amount and interest rate of each Loan made by each Lender,
and all payments made on account of the principal thereof, shall be recorded by
such Lender on its books for its Note, and, prior to any transfer, may be
endorsed by such Lender on a schedule attached to such Note or any continuation
thereof or on any separate record maintained by such Lender. Failure to make any
such notation or to attach a schedule shall not affect any Lender's or the
Borrower's rights or obligations in respect of such Loans or affect the validity
of such transfer by any Lender of its Note. In the event that any Lender's Loan

                                       23
<PAGE>

increases or decreases for any reason (whether pursuant to Section 13.04(b) or
otherwise), upon such Lender's request, the Borrower shall deliver or cause to
be delivered on the effective date of such increase or decrease, a new Note
payable to the order of such Lender in a principal amount equal to its Loan
after giving effect to such increase or decrease, and otherwise duly completed.
The Administrative Agent shall cause each Lender to provide Borrower with
written notice of any transfer.

                                   ARTICLE III
                       Payments of Principal and Interest

      Section 3.01 Repayment of Loans.

            (a) On each Quarterly Date beginning on March 31, 2007 (each such
Quarterly Date being a "Disbursement Date") and thereafter, the Borrower shall
repay principal (to Administrative Agent by payment in cash of immediately
available funds or through Administrative Agent disbursing such funds from the
Lockbox Account when and if such Lockbox Account is established) by an amount
equal to fifty percent (50%) of Free Cash Flow. On February 28, 2006 Borrower
will make a principal payment on the Indebtedness by making a payment to
Administrative Agent in cash of immediately available funds in an amount of
$600,000.

            (b) Notwithstanding the provisions of Section 3.01(a) above, upon
the occurrence and during the continuation of any Event of Default, on each
Quarterly Date during such period the Borrower shall repay principal (to
Administrative Agent by payment in cash of immediately available funds or
through Administrative Agent disbursing such funds from the Lockbox Account when
and if such Lockbox Account is established) by an amount equal to one hundred
percent (100%) of Free Cash Flow.

            (c) Payments made pursuant to Section 3.01(a) and (b) shall be first
applied to Loans that are not Bridge Loans. The Bridge Loans shall be repaid
from equity contributions or other Debt of the Borrower only.

            (d) Notwithstanding anything herein to the contrary, if not paid
prior thereto, the Borrower hereby unconditionally promises to pay to the
Administrative Agent for the account of each Lender the then unpaid principal
amount of such Lender's Loans and the accrued and unpaid interest thereon on the
Maturity Date.

      Section 3.02 Interest.

            (a) Interest Rates. The Borrower will pay to each Lender interest on
the unpaid principal amount of its Loans for the period commencing on the date
that such Loan is made to but excluding the date such Loan shall be paid in full
at the Applicable Rate, but in no event to exceed the Highest Lawful Rate.

            (b) Post-Default Rate. Notwithstanding the foregoing, the Borrower
will pay to the Lenders interest at the Post-Default Rate on the principal of
the Loans, and (to the fullest extent permitted by law) on any fees and other
amounts payable by the Borrower hereunder, under the Notes or under any other

                                       24
<PAGE>

Loan Document, for the period commencing on the date of any Event of Default
until the same is paid in full or all Events of Default are cured or waived
(after as well as before judgment).

            (c) Due Dates. Accrued interest on the Loans shall be due and
payable on the last day of each month and on the Credit Agreement Termination
Date; provided that (i) interest accrued pursuant to Section 3.02(b) shall be
payable on demand and (ii) in the event of any repayment or prepayment of any
Loan pursuant to Section 3.03(a) or Section 3.04, accrued interest on the
principal amount repaid or prepaid shall be payable on the date of such
repayment or prepayment.

            (d) Interest Rate Computations. All interest hereunder shall be
computed on the basis of a year of 360 days, unless such computation would
exceed the Highest Lawful Rate, in which case interest shall be computed on the
basis of a year of 365 days (or 366 days in a leap year), and in each case shall
be payable for the actual number of days elapsed (including the first day but
excluding the last day).

      Section 3.03 Prepayments.

            (a) Voluntary Prepayments. The Borrower may prepay all or any
portion of the Loans upon not less than 10 Business Days prior notice to the
Lenders, which notice shall be irrevocable and shall specify the prepayment date
(which shall be a Business Day) and the amount of the prepayment (which shall be
at least the lesser of $100,000 or the remaining principal balance outstanding
on the Loans) and effective only upon receipt by each Lender, provided that
interest on the principal prepaid, accrued to the prepayment date, shall be paid
on the prepayment date. Each prepayment of the Loans shall be applied ratably to
all Loans then outstanding.

            (b) Reborrowing Prohibited; Application of Prepayments. Any
voluntary or mandatory payments or prepayments on the Loans may not be
reborrowed.

            (c) No Penalty. Prepayments permitted or required under this Article
III shall be without premium or penalty.

      Section 3.04 Mandatory Repayments.

            (a) Bridge Loan Repayment. On or prior to the Bridge Loan
Termination Date, the Borrower shall repay the Bridge Loans together with
accrued interest on such portion of the Bridge Loans so repaid in accordance
with Section 3.02(c).

            (b) Sale of Properties. In the event that the Borrower or its
Subsidiaries sell, assign or otherwise dispose of any of their Oil and Gas
Properties (other than asset sales permitted by Section 10.14(a) and (b), then
the Borrower shall prepay the Loans together with accrued interest on such
portion of the Loans so prepaid in accordance with Section 3.02(c) on the date
of such sale or other disposition of the Oil and Gas Properties occurs in an
aggregate amount equal to, unless otherwise agreed to in writing by the Lenders,
the proceeds of such sale or disposition, less the actual costs and fees
associated with such sale or disposition provided that such costs and fees are
not in excess of 4% of the proceeds from such sale or disposition or are
otherwise approved by the Lenders.

                                   ARTICLE IV
                Payments; Pro Rata Treatment; Sharing of Set-offs

      Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

            (a) Payments by the Borrower. The Borrower shall make each payment
required to be made by it hereunder (whether of principal, interest, fees, or of
amounts payable under Section 5.01, Section 5.02 or otherwise) prior to 12:00
noon, New York City time, on the date when due, in immediately available funds,
without defense, deduction, recoupment, set-off or counterclaim. Fees, once
paid, shall not be refundable unless the Administrative Agent agrees otherwise.
Any amounts received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Administrative Agent at its offices specified in Section
13.01, except that payments pursuant to Section 5.01, Section 5.02 and Section
13.03 shall be made directly to the Persons entitled thereto. The Administrative
Agent shall distribute any such payments received by it for the account of any
other Person to the appropriate recipient promptly following receipt thereof. If
any payment hereunder shall be due on a day that is not a Business Day, the date
for payment shall be extended to the next succeeding Business Day, and, in the
case of any payment accruing interest, interest thereon shall be payable for the
period of such extension. All payments hereunder shall be made in dollars.

            (b) Application of Insufficient Payments. If at any time
insufficient funds are received by and available to the Administrative Agent to
pay fully all amounts of principal, interest and fees then due hereunder, such
funds shall be applied (i) first, towards payment of interest and fees then due
hereunder, ratably among the parties entitled thereto in accordance with the
amounts of interest and fees then due to such parties, and (ii) second, towards
payment of principal then due hereunder, ratably among the parties entitled
thereto in accordance with the amounts of principal then due to such parties.

            (c) Sharing of Payments by Lenders. If any Lender shall, by
exercising any right of set-off or counterclaim or otherwise, obtain payment in
respect of any principal of or interest on any of its Loans resulting in such
Lender receiving payment of a greater proportion of the aggregate amount of its
Loans and accrued interest thereon than the proportion received by any other
Lender, then the Lender receiving such greater proportion shall purchase (for
cash at face value) participations in the Loans of other Lenders to the extent
necessary so that the benefit of all such payments shall be shared by the
Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Loans; provided that (i) if any such
participations are purchased and all or any portion of the payment giving rise
thereto is recovered, such participations shall be rescinded and the purchase
price restored to the extent of such recovery, without interest, and (ii) the
provisions of this Section 4.01(c) shall not be construed to apply to any
payment made by the Borrower pursuant to and in accordance with the express
terms of this Agreement or any payment obtained by a Lender as consideration for
the assignment of or sale of a participation in any of its Loans to any assignee
or participant, other than to the Borrower or any Subsidiary or Affiliate
thereof (as to which the provisions of this Section 4.01(c) shall apply). The
Borrower consents to the foregoing and agrees, to the extent it may effectively

                                       26
<PAGE>

do so under applicable law, that any Lender acquiring a participation pursuant
to the foregoing arrangements may exercise against the Borrower rights of
set-off and counterclaim with respect to such participation as fully as if such
Lender were a direct creditor of the Borrower in the amount of such
participation.

      Section 4.02 Presumption of Payment by the Borrower. Unless the
Administrative Agent shall have received notice from the Borrower prior to the
date on which any payment is due to the Administrative Agent for the account of
the Lenders that the Borrower will not make such payment, the Administrative
Agent may assume that the Borrower has made such payment on such date in
accordance herewith and may, in reliance upon such assumption, distribute to the
Lenders the amount due. In such event, if the Borrower has not in fact made such
payment, then each of the Lenders severally agrees to repay to the
Administrative Agent forthwith on demand the amount so distributed to such
Lenders with interest thereon, for each day from and including the date such
amount is distributed to it to but excluding the date of payment to the
Administrative Agent, at the greater of the Federal Funds Effective Rate and a
rate determined by the Administrative Agent in accordance with banking industry
rules on interbank compensation.

      Section 4.03 Certain Deductions by the Administrative Agent. If any Lender
shall fail to make any payment required to be made by it pursuant to Section
2.02(d) or Section 4.02 then the Administrative Agent may, in its discretion
(notwithstanding any contrary provision hereof), apply any amounts thereafter
received by the Administrative Agent for the account of such Lender to satisfy
such Lender's obligations under such Sections until all such unsatisfied
obligations are fully paid.

                                    ARTICLE V
                             Increased Costs; Taxes

      Section 5.01 Increased Costs.

            (a) Capital Requirements. If any Lender shall be a bank or other
Person subject to any capital adequacy rules, and such Lender reasonably
determines that any Change in Law regarding capital requirements has or would
have the effect of reducing the rate of return on such Lender's capital or on
the capital of such Lender's holding company, if any, as a consequence of this
Agreement or the Loans made by Lenders hereunder, to a level below that which
such Lender or such Lender's holding company could have achieved but for such
Change in Law (taking into consideration such Lender's policies and the policies
of such Lender's holding company with respect to capital adequacy), then from
time to time the Borrower will pay to such Lender, as the case may be, such
additional amount or amounts as will compensate such Lender or such Lender's
holding company for any such reduction in rate of return suffered with respect
to the amounts advanced under the Loans.

            (b) Certificates. A certificate of a Lender setting forth the amount
or amounts necessary to compensate such Lender or its holding company, as the
case may be, as specified in the immediately preceding subsection (a) shall be
delivered to the Borrower and shall be conclusive absent manifest error. The
Borrower shall pay such Lender the amount shown as due on any such certificate
within 10 days after receipt thereof.

                                       27
<PAGE>

            (c) Effect of Failure or Delay in Requesting Compensation. Failure
or delay on the part of any Lender to demand compensation pursuant to this
Section 5.01 shall not constitute a waiver of such Lender's right to demand such
compensation.

      Section 5.02 Taxes.

            (a) Payments Free of Taxes. Any and all payments by or on account of
any obligation of the Borrower or any Guarantor under any Loan Document shall be
made free and clear of and without deduction for any Indemnified Taxes or Other
Taxes; provided that if the Borrower or any Guarantor shall be required to
deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 5.02), the Administrative Agent or Lenders (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower or such Guarantor shall make such
deductions and (iii) the Borrower or such Guarantor shall pay the full amount
deducted to the relevant Governmental Authority in accordance with applicable
law.

            (b) Payment of Other Taxes by the Borrower. The Borrower shall pay
any Other Taxes to the relevant Governmental Authority in accordance with
applicable law.

            (c) Indemnification by the Borrower. The Borrower shall indemnify
the Administrative Agent and each Lender within 10 days after written demand
therefore, for the full amount of any Indemnified Taxes or Other Taxes paid by
the Administrative Agent or such Lender, as the case may be, on or with respect
to any payment by or on account of any obligation of the Borrower hereunder
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section 5.02) and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto,
whether or not such Indemnified Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. A certificate of the
Administrative Agent or a Lender as to the amount of such payment or liability
under this Section 5.02 shall be delivered to the Borrower and shall be
conclusive absent manifest error.

            (d) Evidence of Payments. As soon as practicable, but in any event
within 30 days after receipt of a request by the Administrative Agent of
evidence of any payment of Indemnified Taxes or Other Taxes by the Borrower or a
Guarantor to a Governmental Authority, the Borrower shall deliver to the
Administrative Agent the original or a certified copy of a receipt issued by
such Governmental Authority evidencing such payment, a copy of the return
reporting such payment or other evidence of such payment reasonably satisfactory
to the Administrative Agent.

                      Lockbox Procedures; Casualty Proceeds

      Section 6.01 Lockbox Account.

            (a) If Administrative Agent so elects, the Borrower and the
Administrative Agent shall establish within 10 days of receipt of notice of such
election, and thereafter maintain at the Borrower's expense an interest-bearing

                                       28
<PAGE>

account (the "Lockbox Account") under Administrative Agent's exclusive control
with a bank (the "Lockbox Bank") reasonably acceptable to the Lenders which has
entered into an account control agreement pursuant to which all Revenues to be
received by the Borrower or its Subsidiaries shall be deposited, and the
Borrower shall direct (and hereby agrees to direct) each payor of any Revenues
of the borrower and its Subsidiaries now and in the future to make payment to
such Lockbox Account. The Borrower hereby irrevocably appoints Administrative
Agent as its attorney-in-fact (and such appointment shall be deemed to be
coupled with an interest so long as any Loans remain outstanding) to address any
direction letter or letter-in-lieu of division order executed by the Borrower it
may hold and deliver or have delivered any such letter to any Person purchasing
Hydrocarbons from the Oil and Gas Properties that is not then directing payment
for such Hydrocarbons to the Lockbox Account.

            (b) On each Disbursement Date, Administrative Agent (on behalf of
the Lenders) shall direct the Lockbox Bank to make the following payments from
the Lockbox Account in the following order of priority and to the extent funds
remain available:

                  (i) amounts to the Borrower to (A) pay overriding royalty
interests created under any ORRI Assignment and to pay other royalties and
overriding royalty interests (1) with respect to existing Oil and Gas
Properties, to the extent such burdens exist at the time of the execution of
this Agreement and (2) with respect to Oil and Gas Properties that Borrower
acquires subsequent to the date of this Agreement to the extent such burdens
exist at the time that the Borrower acquires such Oil and Gas Properties and is
payable to non-Affiliated third parties, and (B) remit any revenues attributable
to the working interests of non-Affiliated third parties that were paid to or
received by the Borrower, in each case, as the Lenders determine is reasonably
accurate in its good faith discretion and any applicable severance tax or
ad-valorem tax attributable to all proceeds received by the Borrower;

                  (ii) payment to any third party (including Lenders or any of
their Affiliates) of any amounts due under any Swap Agreement of the Borrower
approved by the Lenders;

                  (iii) Operating Costs;

                  (iv) payment of any cash or cash equivalents representing
proceeds of insurance policies with respect to any casualty to any of the
Borrower's Property (the "Casualty Proceeds"), to the Casualty Proceeds Account
subject to and in accordance with the provisions of Section 6.03;

                  (v) payment of all fees owed to any of the Administrative
Agent or the Lenders then due and unpaid under Section 2.04;

                  (vi) payment of all interest then accrued and unpaid on the
Loans;

                  (vii) payment to the Administrative Agent and the Lenders of
any other amounts due (other than principal on the Loans) under this Agreement
and any of the other Loan Documents;

                                       29
<PAGE>

                  (viii) payment of all principal then due under Section 3.01.;
and

                  (ix) payment of any residual amount to the Borrower.

            (c) The Administrative Agent may, at its option, apply sums in the
Lockbox Account to pay directly to the ultimate payee thereof some or all of the
payments described in Section 6.01, as the Lenders elect, including advances or
prepayment to third Persons of expenditures incurred in the ordinary course of
Borrower's operation of its Properties.

            (d) Upon the Credit Agreement Termination Date, all amounts
remaining in the Lockbox Account shall be disbursed to the Borrower to the
Operating Account.

      Section 6.02 Notice. Immediately following the establishment of the
Lockbox Account, the Borrower shall send Direction Letters, to all Persons that
owe or are expected to owe Cash Receipts to the Borrower or its Subsidiaries,
directing such persons to forward all such amounts directly to the Lockbox
Account. The Borrower hereby irrevocably appoints the Administrative Agent as
its attorney-in-fact (such appointment being coupled with an interest) for
sending any such notice to any Person who is or may become obligated to make any
payment of Cash Receipts to the Borrower. After the establishment of the Lockbox
Account, with respect to Cash Receipts received directly by the Borrower, the
Borrower shall within three Business Days deposit, or cause to be deposited, all
such amounts in the Lockbox Account. If the Borrower has knowledge that any
Person is in receipt of Cash Receipts that would otherwise be properly deposited
in the Lockbox Account, the Borrower shall promptly notify such Person and the
Administrative Agent in writing of such circumstance and shall direct such
Person to deposit, or cause to be deposited, all such amounts in the Lockbox
Account.

      Section 6.03 Casualty Proceeds. All Casualty Proceeds (for collateral
purposes) are hereby assigned by the Borrower to the Administrative Agent, and
the Borrower shall have the right to collect any such payments, and such
payments shall be deposited by the Lenders or the Administrative Agent in an
account at the Lockbox Bank controlled by Administrative Agent (the "Casualty
Proceeds Account"). In the event of any casualty, the Borrower shall deliver
within 30 days, a written report from an engineering firm acceptable to the
Lenders describing the nature of the casualty, the nature of any restoration
required, and a good faith estimate of the cost of such restoration. If the
Lenders in their sole discretion determine that the remediation is not in its
best interests, given the cost of such restoration and the effect such
restoration would have on the amount and timing of repayment of the Loans, then
the Lenders may apply such Casualty Proceeds to the prepayment of the
outstanding principal balance and accrued interest of the Loans and the other
Indebtedness, whether or not such Indebtedness is then due and payable. If the
Lenders determine that such Casualty Proceeds shall be used for restoration,
then the proceeds shall be disbursed from the Casualty Proceeds Account for such
restoration in accordance with procedures reasonably determined by the Lenders
consistent with construction loan funding principles. Notwithstanding the
foregoing, if the Lenders determine that the Casualty Proceeds shall be used for
restoration and such Casualty Proceeds are less than $50,000, then such amount
shall be disbursed from the Casualty Proceeds Account to the Borrower and the
Borrower shall utilize such proceeds solely for restoration of such casualty.

subject to the provisos at the end of such definition.

welfare or the environment, and, to the knowledge of any Loan Party, all such
transport carriers and treatment and disposal facilities have been and are
operating in compliance with Environmental Laws and so as not to pose an
imminent and substantial endangerment to public health or welfare or the

action, investigation or inquiry by any Governmental Authority in connection
with any Environmental Laws.

            (f) to the extent applicable, all Property of each Loan Party
currently satisfies in all material respects any design, operation, and
equipment requirements imposed by the OPA, and no Loan Party has any reason to
believe that such Property, to the extent subject to the OPA, will not be able
to maintain compliance with the OPA requirements during the term of this
Agreement.

            (g) none of the Loan Parties has any known contingent liability or
Remedial Work in connection with any release or threatened release of any oil,
hazardous substance, solid waste or oil and gas waste into the environment.

            (h) none of the Loan Party's oil and gas operations on its Oil and

            (b) None of the Loan Parties is in default nor has any event or
circumstance occurred that, but for the expiration of any applicable grace

<PAGE>

            (i) Neither the Loan Parties nor any ERISA Affiliate is required to
provide security under section 401(a)(29) of the Code due to a Plan amendment
that results in an increase in current liability for the Plan.

information, statements, exhibits, certificates, documents or reports furnished
to either the Administrative Agent or the Lenders by the Loan Parties or any of
their Affiliates in connection with the negotiation of this Agreement and the
other Loan Documents contained any material misstatement of fact or omitted to
state a material fact or any fact necessary to make the statement contained
therein not materially misleading in the light of the circumstances in which
made, as of the time made, and with respect to the Borrower and its Affiliates
taken as a whole. There is no fact peculiar to any Loan Party or any of their
Affiliates which has a Material Adverse Effect or in the future is reasonably
likely to have a Material Adverse Effect and which has not been set forth in
this Agreement, the Loan Documents or the other documents, certificates and
statements furnished to the Administrative Agent and the Lenders by or on behalf
of the Loan Parties or their Affiliates prior to, or on, the Effective Date in
connection with the transactions contemplated hereby. There are no statements or
conclusions in any Reserve Report taken as a whole that are based upon or
include misleading information or fail to take into account material information
regarding the matters reported therein which is (i) supplied by or on behalf of
the Borrower, or (ii) though the information is not supplied by the Borrower,
the Borrower has actual knowledge of its misleading nature.

      Section 8.12 Insurance. Schedule 8.12 attached hereto contains an accurate
and complete description of all material policies of fire, liability, workmen's
compensation and other forms of insurance that are owned or held by or on behalf
of the Loan Parties. All such policies are in full force and effect, all
premiums with respect thereto covering all periods up to and including the date
of the closing have been paid (if due), and no notice of cancellation or
termination has been received with respect to any such policy. Such policies are
sufficient for compliance with all Governmental Requirements pertaining to the
business of the Borrower and all agreements to which the Loan Parties are a
party; are valid, outstanding and enforceable policies; provide adequate
insurance coverage for the assets and operations of the Loan Parties, and to the
knowledge of each Loan Party, in at least such amounts and against at least such
risks (but including in any event public liability) as are usually insured
against in the same general area by companies engaged in the same or a similar
business; will remain in full force and effect through the respective dates set
forth in Schedule 8.12; and will not in any way be affected by, or terminate or
lapse by reason of, the transactions contemplated by this Agreement and the Loan
Documents. None of the Loan Parties (nor to any Loan Parties' knowledge any
prior owner of the Oil and Gas Properties) has been refused any insurance with
respect to its assets or operations, nor has it been limited below usual and
customary policy limits, by an insurance carrier to which it has applied for any
insurance or with which it has carried insurance during the last three years.
The Administrative Agent and the Lenders have been named as additional insureds
in respect of such liability insurance policies and the Administrative Agent has
been named as loss payee with respect to property loss insurance.

      Section 8.13 Restriction on Liens. None of the Loan Parties is a party to
any material agreement or arrangement, or subject to any order, judgment, writ
or decree, that either restricts or purports to restrict its ability to grant
Liens to the Administrative Agent and the Lenders on or in respect of their
Properties to secure the Indebtedness and the Loan Documents.

      Section 8.14 Subsidiaries. Except as set forth on Schedule 8.14, the
Borrower has no Subsidiaries.

      Section 8.15 Location of Business and Offices. The Borrower's jurisdiction
of formation is Delaware; the name of the Borrower as listed in the public
records of its jurisdiction of formation is Dune Energy, Inc.; and the
organizational identification number of the Borrower in its jurisdiction of
organization is 2969625 (or, in each case, as set forth in a notice delivered to
the Administrative Agent pursuant to Section 9.01(n) in accordance with Section
13.01). The Borrower's principal place of business and chief executive offices
are located at the address specified in Section 13.01 (or as set forth in a
notice delivered pursuant to Section 9.01(n) and Section 13.01(c)). Each
Subsidiary's jurisdiction of formation, name as listed in the public records of
its jurisdiction of formation, formation identification number in its
jurisdiction of formation, and the location of its principal place of business
and chief executive office is stated on Schedule 8.14 (or as set forth in a

      Section 8.16 Properties; Titles, Etc.

            (a) After giving full effect to the Excepted Liens and except for
the ORRI Assignment, each of the Loan Parties has good and defensible title to
the Oil and Gas Properties evaluated in the most recently delivered Reserve
Report and good title to all its personal Properties. After giving full effect
to the Excepted Liens, the Loan Party specified as the owner owns the net
interests in production attributable to the Hydrocarbon Interests as reflected
in the most recently delivered Reserve Report, and the ownership of such
Properties shall not in any material respect obligate such Loan Party to bear
the costs and expenses relating to the maintenance, development and operations
of each such Property in an amount in excess of the working interest of each
Property set forth in the most recently delivered Reserve Report that is not
offset by a corresponding proportionate increase in such Loan Party's net
revenue interest in such Property. All information provided to the preparer in
the most recently delivered Reserve Report is true and correct in all material
respects as of the date thereof and to the knowledge of the Borrower, such
Reserve Report provides a reasonable estimate of the reserves of the Borrower
and its Subsidiaries as of the date such Reserve Report was prepared and based
on the then available information. No litigation or claims are currently
pending, or to the best knowledge of the Borrower, threatened which could
reasonably be expected to have a material adverse effect on any Loan Party's
title to the Oil and Gas Properties.

            (b) All leases and agreements referenced in the Initial Reserve
Report or the title information delivered in connection herewith or otherwise
are valid and subsisting, in full force and effect, and there exists no default
or event or circumstance which with the giving of notice or the passage of time
or both would give rise to a default under any such lease or leases, which would
affect in any material respect the conduct of the business of the Loan Parties.

                                       41
<PAGE>

            (c) The Property presently owned, leased or licensed by the Loan
Parties, including, without limitation, all easements and rights of way, is all
of the Property necessary to permit the Loan Parties to conduct their business
in all material respects in the manner as would a prudent operator and Borrower
and its Subsidiaries will not be required to acquire any material assets to
continue the current operations of Borrower's and its Subsidiaries' Properties

            (e) Each Loan Party owns, or is licensed to use, all trademarks,
tradenames, copyrights, patents and other intellectual Property material to its
business, and the use thereof by such Loan Party does not infringe upon the
rights of any other Person, except for any such infringements that, individually
or in the aggregate, could not reasonably be expected to result in a Material
Adverse Effect. The Loan Parties either own or have valid licenses or other
rights to use all databases, geological data, geophysical data, engineering
data, seismic data, maps, interpretations and other technical information used
or usable in the conduct of their businesses, subject to the limitations
contained in the agreements governing the use of the same, which limitations are

      Section 8.17 Maintenance of Properties. The Oil and Gas Properties (and
Properties unitized therewith) have been maintained, operated and developed in a
good and workmanlike manner and in material conformity with all Government
Requirements and in material conformity with the provisions of all leases,
subleases or other contracts comprising a part of the Hydrocarbon Interests and
other contracts and agreements forming a part of the Oil and Gas Properties.
Specifically in connection with the foregoing (a) no Oil and Gas Property is
subject to having allowable production reduced below the full and regular
allowable (including the maximum permissible tolerance) because of any
overproduction (whether or not the same was permissible at the time) and (b)
none of the wells comprising a part of the Oil and Gas Properties (or Properties
unitized therewith) is deviated from the vertical more than the maximum
permitted by Government Requirements, and such wells are, in fact, bottomed
under and are producing from, and the well bores are wholly within, the Oil and
Gas Properties (or in the case of wells located on Properties unitized
therewith, such unitized Properties). All pipelines, wells, gas processing
plants, platforms and other material improvements, fixtures and equipment owned
in whole or in part by the Loan Parties that are necessary to conduct normal
operations are being maintained in a state adequate to conduct normal
operations, and with respect to such of the foregoing that are operated by any

receiving full payment therefor. Except as set forth on Schedule 8.18, no
material gas imbalances exist with respect to any of the Oil and Gas Properties
of any Loan Party. Except as set forth in Schedule 8.18, none of the Oil and Gas

whereby payment for production therefrom is to be deferred for a substantial
period of time after the month in which such production is delivered (i.e., in
the case of oil, not in excess of 60 days, and in the case of gas, not in excess
of 90 days). Except as set forth on Schedule 8.18, none of the Oil and Gas
Properties of the Borrower and its Subsidiaries is subject to a contractual or
other arrangement for the sale of oil or gas production for a fixed price which
cannot be canceled on 90 days (or less) notice or which contains commercial

substantially in accordance with the terms of the relevant contract and are not
having deliveries curtailed substantially below the subject Property's delivery
capacity), no material agreements exist that are not cancelable on 60 days
notice or less without penalty or detriment for the sale of production from any
the Borrower's or its Subsidiaries' Hydrocarbons (including, without limitation,
calls on or other rights to purchase, production, whether or not the same are
currently being exercised) that (a) pertain to the sale of production at a fixed
price and (b) have a maturity or expiry date of longer than six (6) months from
the date hereof. All proceeds from the sale of the Borrower's or its
Subsidiaries' interests in Hydrocarbons from its Oil and Gas Properties will be
paid in full to the applicable party by the purchaser thereof on a timely basis,
and none of such proceeds are currently being held in suspense by such purchaser
or any other Person. Except as set forth in Schedule 8.19, none of the Oil and
Gas Properties of the Borrower or its Subsidiaries are subject to any
contractual or other arrangement whereby payment for production therefrom is to
be deferred for a substantial period of time after the month in which such
production is delivered (i.e., in the case of oil, not in excess of 60 days, and
in the case of gas, not in excess of 90 days).

the Administrative Agent or the Lenders to be cured within the 60-day period or
the Borrower does not comply with the requirements to provide acceptable title
information covering 90% of the value of the Oil and Gas Properties evaluated in
the most recent Reserve Report, such default shall not be a Default, but instead
the Administrative Agent shall have the right to exercise the following remedy
in its sole discretion from time to time, and any failure to so exercise this
remedy at any time shall not be a waiver as to future exercise of the remedy by
the Administrative Agent.

      Section 9.14 Additional Collateral; Additional Guarantors.

            (a) Promptly after the end of each month, the Borrower shall review
the current Collateral to ascertain whether all Oil and Gas Properties are
Collateral. If the Collateral does not represent all such Properties, then the
Borrower shall, and shall cause its Subsidiaries (if any) to, grant to the
Administrative Agent as security for the Indebtedness a senior Lien interest
(subject only to Excepted Liens of the type described in clauses (a) to (j) of
the definition thereof, but subject to the provisos at the end of such
definition) on additional Oil and Gas Properties not already subject to a Lien
of the Security Instruments such that after giving effect thereto, the
Collateral will represent all such Properties. All such Liens will be created
and perfected by and in accordance with the provisions of deeds of trust,
security agreements and financing statements or other Security Instruments, all
in form and substance reasonably satisfactory to the Administrative Agent and in
sufficient executed (and acknowledged where necessary or appropriate)
counterparts for recording purposes. In order to comply with the foregoing, if

Security Instruments.

      Section 9.15 ERISA Compliance. The Borrower will promptly furnish and will

Affiliate is taking or proposes to take with respect thereto, and, when known,
any action taken or proposed by the Internal Revenue Service, the Department of
Labor or the PBGC with respect thereto, and (c) immediately upon receipt
thereof, copies of any notice of the PBGC's intention to terminate or to have a
trustee appointed to administer any Plan. With respect to each Plan (other than
a Multiemployer Plan), the Borrower will, and will cause each Subsidiary and
ERISA Affiliate to, (i) satisfy in full and in a timely manner, without
incurring any late payment or underpayment charge or penalty and without giving
rise to any lien, all of the contribution and funding requirements of section
412 of the Code (determined without regard to subsections (d), (e), (f) and (k)
thereof) and of section 302 of ERISA (determined without regard to sections 303,
304 and 306 of ERISA), and (ii) pay, or cause to be paid, to the PBGC in a
timely manner, without incurring any late payment or underpayment charge or
penalty, all premiums required pursuant to sections 4006 and 4007 of ERISA.

      Section 9.16 Swap Agreements. The Borrower shall from time to time enter

anticipated projected production from Proved Developed Producing Reserves from
the Borrower's or its Subsidiaries' Oil and Gas Properties (net to the Borrower
or Subsidiary, as applicable) for each month during the term of this Agreement
for each of crude oil and natural gas, calculated separately. The Borrower shall
neither assign, terminate or unwind any such Swap Agreements nor sell any Swap
Agreements if the effect of such action (when taken together with any other Swap

Lenders, the Borrower agrees to and will cause any Subsidiary to, convey to the
Lenders or their designees, in undivided shares proportionate to their
respective Commitments, an overriding royalty interest in the aggregate amount
specified below in and to the Oil and Gas Properties referred to below. The
overriding royalty shall be conveyed with respect to each (i) Oil and Gas
Property currently owned by the Borrower and any Subsidiary and (ii) any
additional Oil and Gas Property acquired by the Borrower or any Subsidiary or in
which the Borrower or any Subsidiary acquires an additional interest, in each
case, after the effective date through the date this Agreement is terminated.

            (b) The overriding royalty interest in any Oil and Gas Property
required to be conveyed shall equal two percent (2.00%) of 8/8ths
(proportionately reduced to the undivided working interest owned by the Borrower
and any of its Subsidiaries therein, as such working interest may increase or
decrease from time to time in accordance with the provisions of any agreement in
effect at the time of creation of the relevant overriding royalty interest) in
each such Oil and Gas Property other than with respect to the Bayou Couba

                                       56
<PAGE>

Properties for depths below 10,000 feet in which case the overriding royalty
interest in any such Oil and Gas Property required to be conveyed shall equal
one percent (1.00%) of 8/8ths (proportionately reduced to the undivided working
interest owned by the Borrower and any of its Subsidiaries therein, as such
working interest may increase or decrease from time to time in accordance with
the provisions of any agreement in effect at the time of creation of the
relevant overriding royalty interest). In addition to the above, in the event
that the Bridge Loans have not been repaid in full prior to the Bridge Loan
Termination Date, Borrower will grant an additional one percent (1.00%)
(proportionately reduced to the undivided working interest owned by the Borrower
and any of its Subsidiaries therein, as such working interest may increase or
decrease from time to time in accordance with the provisions of any agreement in
effect at the time of creation of the relevant overriding royalty interest) in
each Oil and Gas Property of the Borrower and its Subsidiaries on the Bridge
Loan Termination Date and thereafter on each monthly anniversary date thereafter
until such time that the Bridge Loans have been repaid in full. The overriding
royalty shall be subject to the terms and conditions set forth in the form of
the ORRI Assignment, and any other agreements currently in existence as of the
time of the acquisition of such Properties and validly affecting the underlying
leases.

            (c) An overriding royalty interest required to be conveyed hereby:
(i) with respect to any currently owned Oil and Gas Property shall be effective
as to Hydrocarbons produced on and after the first day of the first calendar
month following the date upon which this Agreement is executed and with respect
to any subsequently acquired Oil and Gas Property or increased interest in a
currently owned Oil and Gas Property shall be effective as to Hydrocarbons
produced on and after the first day of the first calendar month following the
date of the relevant acquisition, (ii) shall be conveyed by a conveyance
substantially in the form of the ORRI Assignment executed by the appropriate
grantor and filed for recording by the Borrower promptly after the receipt,
delivery and recording of applicable assignments into the Borrower or any
Subsidiary establishing its interest of record in any Oil and Gas Properties and
shall be delivered by the Borrower to the Lenders or their designees promptly
after its return from recording, and (iii) shall survive any termination of this
Agreement.

            (d) If, prior to finalization of the division order process, the
Borrower or any Subsidiary receives proceeds of production from a well with
respect to which the Borrower or any Subsidiary is required to convey an
overriding royalty interest under this Section 9.17, the Borrower shall estimate
the amount of such revenue payable on account of the overriding royalty interest
and shall pay or cause the relevant subsidiary to pay such estimated proceeds to
the Lenders; provided that, upon the completion of the division order process,
if any amounts are determined to have been overpaid or underpaid to the Lenders
or their designees, the Borrower or any relevant Subsidiary and the Lenders or
their designees shall promptly make appropriate adjustments among themselves to
give effect to the correct division of interests, retroactive to the effective
date of such overriding royalty interest.

            (e) Within sixty days (60) after the end of each fiscal quarter, the
Borrower will prepare a summary of all wells spudded on the Oil and Gas
Properties of the Borrower or any Subsidiary during the preceding fiscal
quarter. Such summary shall indicate the date each well was completed (or
anticipated to be completed) and those wells for which an overriding royalty

                                       57
<PAGE>

interest pursuant to Section 9.17(c) above has been recorded in the appropriate
land records and delivered to the Lenders. For those wells where no overriding
royalty interest has been filed of record, an approximate date of when the
Borrower expects such overriding royalty interest to be recorded.

      Section 9.18 Partner Metrics. If requested by the Arranger and consented
to by the Borrower, the Borrower will cooperate with the Arranger and take all
reasonable actions as may be required in order to implement the Partner Metrics
reporting package on a timely basis.

      Section 9.19 Marketing Activities.

            (a) The Borrower will not, and will not permit any of its
Subsidiaries to, engage in marketing activities for any Hydrocarbons or enter
into any contracts related thereto other than (i) contracts for the sale of
Hydrocarbons scheduled or reasonably estimated to be produced from their proved
Oil and Gas Properties during the period of such contract, (ii) contracts for
the sale of Hydrocarbons scheduled or reasonably estimated to be produced from
proved Oil and Gas Properties of third parties during the period of such
contract associated with the Oil and Gas Properties of the Borrower and its
Subsidiaries that the Borrower or one of its Subsidiaries has the right to
market pursuant to joint operating agreements, unitization agreements or other
similar contracts that are usual and customary in the oil and gas business and
(iii) other contracts for the purchase and/or sale of Hydrocarbons of third
parties (A) that have generally offsetting provisions (i.e. corresponding
pricing mechanics, delivery dates and points and volumes) such that no
"position" is taken and (B) for which appropriate credit support has been taken
to alleviate the material credit risks of the counterparty thereto.

            (b) All Hydrocarbons produced from the Oil and Gas Properties of
Borrower and its Subsidiaries shall be marketed on an arms length basis using
one or more Persons that are not Affiliates of the Borrower.

      Within 30 days of the Effective Date, Borrower shall provide legal
opinions in form and substance reasonably satisfactory to the Administrative
Agent with respect to the Subordinated Debt.

could reasonably be expected to have a Material Adverse Effect and (B) such
Default remains unremedied for a period of 30 days after the earlier of A. the
date upon which a Responsible Officer knew or reasonably should have known of
such Default and B. the date upon which written notice thereof is given to the
Borrower by the Administrative Agent.

            (o) The Borrower or any Subsidiary fails to duly observe, perform or
comply with any agreements with any Person or any term or condition of any
instrument, if such agreement or instrument is materially significant to the
Borrower or to the Borrower and its Subsidiaries on a consolidated bases, and
such failure is not remedied within the applicable grace period (if any)
provided in such agreement or instrument.

            (p) a Change in Control shall occur.

      Section 11.02 Remedies.

            (a) In the case of an Event of Default other than one described in
Section 11.01(h), Section 11.01(i) or Section 11.01(j), at any time thereafter
during the continuance of such Event of Default, the Administrative Agent may,
and at the request of the Lenders, shall, by notice to the Borrower, declare the
Notes and the Loans then outstanding to be due and payable in whole (or in part,
in which case any principal not so declared to be due and payable may thereafter
be declared to be due and payable), and thereupon the principal of the Loans so
declared to be due and payable, together with accrued interest thereon and all
fees and other obligations of the Borrower and the Guarantors accrued hereunder
and under the Notes and the other Loan Documents, shall become due and payable
immediately, without presentment, demand, protest, notice of intent to
accelerate, notice of acceleration or other notice of any kind, all of which are
hereby waived by the Borrower and each Guarantor; and in case of an Event of
Default described in Section 11.01(h), Section 11.01(i) or Section 11.01(j), the
Notes and the principal of the Loans then outstanding, together with accrued
interest thereon and all fees and the other obligations of the Borrower and the
Guarantors accrued hereunder and under the Notes and the other Loan Documents,
shall automatically become due and payable, without presentment, demand, protest
or other notice of any kind, all of which are hereby waived by the Borrower and
each Guarantor.

            (b) In the case of the occurrence and continuance of an Event of
Default, the Administrative Agent is authorized to complete the Letters-in-Lieu
and/or Direction Letters and deliver same, and the Administrative Agent and the
Lenders will have all other rights and remedies available at law and equity.

            (c) All proceeds realized from the liquidation or other disposition
of collateral or otherwise received after maturity of the Notes, whether by
acceleration or otherwise, shall be applied: first, to reimbursement of expenses
and indemnities provided for in this Agreement and the Security Instruments;
second, to accrued interest on the Notes; third, to fees; fourth, pro rata to
principal outstanding on the Notes and Indebtedness referred to in clause (b) of
the definition of "Indebtedness" owing to a Lender or an Affiliate of a Lender;
and any excess shall be paid to the Borrower or as otherwise required by any
Governmental Requirement.

      Section 11.03 Disposition of Proceeds. The Security Instruments contain an
assignment by the Borrower and/or the Guarantors unto and in favor of the
Administrative Agent for the benefit of the Lenders of all of the Borrower's or
each Guarantor's interest in and to production and all proceeds attributable
thereto which may be produced from or allocated to the Collateral. The Security
Instruments further provide in general for the application of such proceeds to
the satisfaction of the Indebtedness and other obligations described therein and
secured thereby. Notwithstanding the assignment contained in such Security
Instruments, until the occurrence of an Event of Default, (a) the Administrative
Agent and the Lenders agree that they will neither notify the purchaser or
purchasers of such production nor take any other action to cause such proceeds
to be remitted to the Administrative Agent or the Lenders, but the Lenders will
instead permit such proceeds to be paid to the Borrower and its Subsidiaries and
(b) the Lenders hereby authorize the Administrative Agent to take such actions
as may be necessary to cause such proceeds to be paid to the Borrower and/or
such Subsidiaries.

                            The Administrative Agent

      Section 12.01 Appointment; Powers. Each of the Lenders hereby irrevocably
appoints the Administrative Agent as its agent and authorizes the Administrative
Agent to take such actions on its behalf and to exercise such powers as are
delegated to the Administrative Agent by the terms hereof and the other Loan
Documents, together with such actions and powers as are reasonably incidental
thereto.

      Section 12.02 Duties and Obligations of Administrative Agent. The
Administrative Agent shall not have any duties or obligations except those
expressly set forth in the Loan Documents. Without limiting the generality of
the foregoing, (a) the Administrative Agent shall not be subject to any
fiduciary or other implied duties, regardless of whether a Default has occurred
and is continuing, (b) the Administrative Agent shall not have any duty to take
any discretionary action or exercise any discretionary powers, except as
provided in Section 12.03, and (c) except as expressly set forth herein, the
Administrative Agent shall not have any duty to disclose, and shall not be
liable for the failure to disclose, any information relating to the Borrower or
any of its Subsidiaries that is communicated to or obtained by the entity
serving as Administrative Agent or any of its Affiliates in any capacity. The
Administrative Agent shall be deemed not to have knowledge of any Default unless
and until written notice thereof is given to the Administrative Agent by the
Borrower or a Lender, and shall not be responsible for or have any duty to
ascertain or inquire into (i) any statement, warranty or representation made in
or in connection with this Agreement or any other Loan Document, (ii) the
contents of any certificate, report or other document delivered hereunder or
under any other Loan Document or in connection herewith or therewith, (iii) the
performance or observance of any of the covenants, agreements or other terms or
conditions set forth herein or in any other Loan Document, (iv) the validity,
enforceability, effectiveness or genuineness of this Agreement, any other Loan
Document or any other agreement, instrument or document, (v) the satisfaction of
any condition set forth in Article VII or elsewhere herein, other than to
confirm receipt of items expressly required to be delivered to the
Administrative Agent or as to those conditions precedent expressly required to
be to the Administrative Agent's satisfaction, (vi) the existence, value,
perfection or priority of any collateral security or the financial or other
condition of the Borrower and its Subsidiaries or any other obligor or
guarantor, or (vii) any failure by the Borrower or any other Person (other than
itself) to perform any of its obligations hereunder or under any other Loan
Document or the performance or observance of any covenants, agreements or other
terms or conditions set forth herein or therein.

      Section 12.03 Action by Administrative Agent. The Administrative Agent
shall not have any duty to take any discretionary action or exercise any
discretionary powers, except discretionary rights and powers expressly
contemplated hereby that the Administrative Agent is required to exercise in
writing as directed by the Lenders and in all cases the Administrative Agent
shall be fully justified in failing or refusing to act hereunder or under any
other Loan Documents unless it shall (a) receive written instructions from the
Lenders specifying the action to be taken and (b) be indemnified to its
satisfaction by the Lenders against any and all liability and expenses which may
be incurred by it by reason of taking or continuing to take any such action. The
instructions as aforesaid and any action taken or failure to act pursuant
thereto by the Administrative Agent shall be binding on all of the Lenders. If a
Default has occurred and is continuing, then the Administrative Agent shall take
such action with respect to such Default as shall be directed by the Lenders in
the written instructions (with indemnities) described in this Section 12.03,

                                       70
<PAGE>

provided that, unless and until the Administrative Agent shall have received
such directions, the Administrative Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such
Default as it shall deem advisable in the best interests of the Lenders. In no
event, however, shall the Administrative Agent be required to take any action
which exposes the Administrative Agent to personal liability or which is
contrary to this Agreement, the Loan Documents or applicable law. The
Administrative Agent shall not be liable for any action taken or not taken by it
with the consent or at the request of the Lenders, and otherwise the
Administrative Agent shall not be liable for any action taken or not taken by it
hereunder or under any other Loan Document or under any other document or
instrument referred to or provided for herein or therein or in connection
herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for its own
gross negligence or willful misconduct.

      Section 12.04 Reliance by Administrative Agent. The Administrative Agent
shall be entitled to rely upon, and shall not incur any liability for relying
upon, any notice, request, certificate, consent, statement, instrument, document
or other writing believed by it to be genuine and to have been signed or sent by
the proper Person. The Administrative Agent also may rely upon any statement
made to it orally or by telephone and believed by it to be made by the proper
Person, and shall not incur any liability for relying thereon and each of the
Borrower and the Lenders hereby waives the right to dispute the Administrative
Agent's record of such statement, except in the case of gross negligence or
willful misconduct by the Administrative Agent. The Administrative Agent may
consult with legal counsel (who may be counsel for the Borrower), independent
accountants and other experts selected by it, and shall not be liable for any
action taken or not taken by it in accordance with the advice of any such
counsel, accountants or experts. The Administrative Agent may deem and treat the
payee of any Note as the holder thereof for all purposes hereof unless and until
a written notice of the assignment or transfer thereof permitted hereunder shall
have been filed with the Administrative Agent.

      Section 12.05 Subagents. The Administrative Agent may perform any and all
its duties and exercise its rights and powers by or through any one or more
sub-agents appointed by the Administrative Agent. The Administrative Agent and
any such sub-agent may perform any and all its duties and exercise its rights
and powers through their respective Related Parties. The exculpatory provisions
of the preceding Sections of this Article XII shall apply to any such sub-agent
and to the Related Parties of the Administrative Agent and any such sub-agent,
and shall apply to their respective activities in connection with the
syndication of the credit facilities provided for herein as well as activities
as Administrative Agent.

      Section 12.06 Resignation or Removal of Administrative Agent. Subject to
the appointment and acceptance of a successor Administrative Agent as provided
in this Section 12.06, the Administrative Agent may resign at any time by
notifying the Lenders and the Borrower, and the Administrative Agent may be
removed at any time with or without cause by all of the Lenders. Upon any such
resignation or removal, the Lenders shall have the right, in consultation with
the Borrower, to appoint a successor. If no successor shall have been so
appointed by the Lenders and shall have accepted such appointment within 30 days
after the retiring Administrative Agent gives notice of its resignation or
removal of the retiring Administrative Agent, then the retiring Administrative
Agent may, on behalf of the Lenders, appoint a successor Administrative Agent.
Upon the acceptance of its appointment as the Administrative Agent hereunder by

                                       71
<PAGE>

a successor, such successor shall succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent, and
the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder. The fees payable by the Borrower to a successor
Administrative Agent shall be the same as those payable to its predecessor
unless otherwise agreed between the Borrower and such successor. After the
Administrative Agent's resignation hereunder, the provisions of this Article XII
and Section 13.03 shall continue in effect for the benefit of such retiring
Administrative Agent, its sub-agents and their respective Related Parties in
respect of any actions taken or omitted to be taken by any of them while it was
acting as Administrative Agent.

      Section 12.07 Agents as Lenders. The party serving as the Administrative
Agent hereunder shall have the same rights and powers in its capacity as a
Lender as any other Lender and may exercise the same as though it were not the
Administrative Agent, and such party and its Affiliates may accept deposits
from, lend money to and generally engage in any kind of business with the
Borrower or any Consolidated Subsidiary or other Affiliate thereof as if it were
not the Administrative Agent hereunder.

      Section 12.08 No Reliance. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent or any other
Lender and based on such documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement and each
other Loan Document to which it is a party. Each Lender also acknowledges that
it will, independently and without reliance upon the Administrative Agent or any
other Lender and based on such documents and information as it shall from time
to time deem appropriate, continue to make its own decisions in taking or not
taking action under or based upon this Agreement, any other Loan Document, any
related agreement or any document furnished hereunder or thereunder. The
Administrative Agent shall not be required to keep itself informed as to the
performance or observance by the Borrower or any of its Subsidiaries of this
Agreement, the Loan Documents or any other document referred to or provided for
herein or to inspect the Properties or books of the Borrower or its
Subsidiaries. Except for notices, reports and other documents and information
expressly required to be furnished to the Lenders by the Administrative Agent
hereunder, neither the Administrative Agent nor the Arranger shall have any duty
or responsibility to provide any Lender with any credit or other information
concerning the affairs, financial condition or business of the Borrower (or any
of its Affiliates) which may come into the possession of such Agent or any of
its Affiliates. In this regard, each Lender acknowledges that Vinson & Elkins
L.L.P. is acting in this transaction as special counsel to the Administrative
Agent only, except to the extent otherwise expressly stated in any legal opinion
or any Loan Document. Each other party hereto will consult with its own legal
counsel to the extent that it deems necessary in connection with the Loan
Documents and the matters contemplated therein.

      Section 12.09 Authority of Administrative Agent to Release Collateral and
Liens. Each Lender hereby authorizes the Administrative Agent to release any
collateral that is permitted to be sold or released pursuant to the terms of the
Loan Documents. Each Lender hereby authorizes the Administrative Agent to
execute and deliver to the Borrower, at the Borrower's sole cost and expense,

                                       72
<PAGE>

any and all releases of Liens, termination statements, assignments or other
documents reasonably requested by the Borrower in connection with any sale or
other disposition of Property to the extent such sale or other disposition is
permitted by the terms of Section 10.14 or is otherwise authorized by the terms
of the Loan Documents.

unless otherwise agreed by the Administrative Agent and the applicable Lender.
The Administrative Agent or the Borrower may, in its discretion, agree to accept
notices and other communications to it hereunder by electronic communications
pursuant to procedures approved by it; provided that approval of such procedures
may be limited to particular notices or communications.

            (c) Any party hereto may change its address or telecopy number for

      Section 13.02 Waivers; Amendments.

            (a) No failure on the part of the Administrative Agent, any Lender,
or the Arranger to exercise and no delay in exercising, and no course of dealing
with respect to, any right, power or privilege, or any abandonment or
discontinuance of steps to enforce such right, power or privilege, under any of
the Loan Documents shall operate as a waiver thereof, nor shall any single or

                                       73
<PAGE>

partial exercise of any right, power or privilege under any of the Loan
Documents preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. The rights and remedies of the Administrative
Agent and the Lenders hereunder and under the other Loan Documents are
cumulative and are not exclusive of any rights or remedies that they would
otherwise have. No waiver of any provision of this Agreement or any other Loan
Document or consent to any departure by the Borrower therefrom shall in any
event be effective unless the same shall be permitted by Section 13.02(b), and
then such waiver or consent shall be effective only in the specific instance and
for the purpose for which given. Without limiting the generality of the
foregoing, the making of a Loan shall not be construed as a waiver of any
Default, regardless of whether the Administrative Agent or any Lenders may have
had notice or knowledge of such Default at the time.

            (b) Neither this Agreement nor any provision hereof nor any Security
Instrument nor any provision thereof may be waived, amended or modified except
pursuant to an agreement or agreements in writing entered into by the Borrower
and the Lenders or by the Borrower and the Administrative Agent with the consent
of all of the Lenders.

      Section 13.03 Expenses, Indemnity; Damage Waiver.

photocopy, mailing, courier, telephone and other similar expenses, and the cost
of environmental audits and surveys and appraisals, in connection with the
ongoing enforcement and performance of the credit facilities provided for herein
as Administrative Agent deems appropriate, the preparation, negotiation,
execution, delivery and administration (both before and after the execution
hereof and including advice of counsel to the Administrative Agent as to the
rights and duties of the Administrative Agent and the Lenders with respect
thereto) of this Agreement and the other Loan Documents and any amendments,
modifications or waivers of or consents related to the provisions hereof or
thereof (whether or not the transactions contemplated hereby or thereby shall be
consummated), (ii) all costs, expenses, Taxes, assessments and other charges
incurred by the Administrative Agent or any Lender in connection with any
filing, registration, recording or perfection of any security interest

Administrative Agent or any Lender, including the fees, charges and

ARRANGER, AND EACH LENDER, AND EACH RELATED PARTY OF ANY OF THE FOREGOING
PERSONS (EACH SUCH PERSON BEING CALLED AN "INDEMNITEE") AGAINST, AND HOLD EACH
INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES AND
RELATED EXPENSES, INCLUDING THE REASONABLE FEES, CHARGES AND DISBURSEMENTS OF

                                       74
<PAGE>

ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE
ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (i) THE EXECUTION OR
DELIVERY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY AGREEMENT OR
INSTRUMENT CONTEMPLATED HEREBY OR THEREBY, THE PERFORMANCE BY THE PARTIES HERETO
OR THE PARTIES TO ANY OTHER LOAN DOCUMENT OF THEIR RESPECTIVE OBLIGATIONS
HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED
HEREBY OR BY ANY OTHER LOAN DOCUMENT, (ii) THE FAILURE OF THE BORROWER OR ANY
SUBSIDIARY TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS
AGREEMENT, OR WITH ANY GOVERNMENTAL REQUIREMENT, (iii) ANY INACCURACY OF ANY

THE PROCEEDS THEREFROM, (v) ANY OTHER ASPECT OF THE LOAN DOCUMENTS, (vi) THE

OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF
THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND
REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, AND SUCH INDEMNITY
SHALL EXTEND TO EACH INDEMNITEE NOTWITHSTANDING THE SOLE OR CONCURRENT
NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE,
WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL
TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF

<PAGE>

FAULT ON ANY ONE OR MORE OF THE INDEMNITEES; PROVIDED THAT SUCH INDEMNITY SHALL
NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS,
DAMAGES, LIABILITIES OR RELATED EXPENSES ARE DETERMINED BY A COURT OF COMPETENT
JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE. PROVIDED, HOWEVER,
ADMINISTRATIVE AGENT WILL ENDEAVOR TO NOTIFY BORROWER OF ANY MATTER IN WHICH
ADMINISTRATIVE AGENT OR LENDERS WILL SEEK INDEMNIFICATION FOR UNDER THIS
AGREEMENT, BUT FAILURE TO NOTIFY BORROWER IN A TIMELY MANNER WILL NOT PREJUDICE
ADMINISTRATIVE AGENT'S OR ANY LENDER'S RIGHTS TO INDEMNIFICATION UNDER THIS
AGREEMENT IN ANY WAY.

            (c) To the extent that the Borrower fails to pay any amount required
to be paid by it to the Administrative Agent under Section 13.03(a) or (b), each
Lender severally agrees to pay to such Administrative Agent such Lender's
Applicable Percentage (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount;
provided that the unreimbursed expense or indemnified loss, claim, damage,
liability or related expense, as the case may be, was incurred by or asserted
against such Administrative Agent in its capacity as such.

            (d) To the extent permitted by applicable law, the Borrower shall
not assert, and hereby waives, any claim against any Indemnitee, on any theory
of liability, for special, indirect, consequential or punitive damages (as
opposed to direct or actual damages) arising out of, in connection with, or as a
result of, this Agreement, any other Loan Document or any agreement or
instrument contemplated hereby or thereby, the Transactions, any Loan or the use
of the proceeds thereof.

            (e) All amounts due under this Section 13.03 shall be payable
promptly after written demand therefor.

      Section 13.04 Successors and Assigns.

            (a) The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that (i) the Borrower may not assign or otherwise
transfer any of its rights or obligations hereunder without the prior written
consent of each Lender (and any attempted assignment or transfer by the Borrower
without such consent shall be null and void) and (ii) no Lender may assign or
otherwise transfer its rights or obligations hereunder except in accordance with
this Section 13.04. Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any Person (other than the parties hereto, their
respective successors and assigns permitted hereby, Participants (to the extent
provided in Section 13.04(c)) and, to the extent expressly contemplated hereby,
the Related Parties of each of the Administrative Agent and the Lenders) any
legal or equitable right, remedy or claim under or by reason of this Agreement.

            (b) (i) Subject to the conditions set forth in Section 13.04(b)(ii),
any Lender may assign to one or more assignees all or a portion of its rights
and obligations under this Agreement (including all or a portion of its
Commitment and the Loans at the time owing to it) without the prior written
consent of the Borrower.

                  (ii) Assignments shall be subject to the following conditions:

                                       76
<PAGE>

                        (A) except in the case of an assignment to a Lender or
an Affiliate of a Lender or an assignment of the entire remaining amount of the
assigning Lender's Commitment, the amount of the Commitment of the assigning
Lender subject to each such assignment (determined as of the date the Assignment
and Assumption with respect to such assignment is delivered to the
Administrative Agent) shall not be less than $100,000 unless each of the
Borrower and the Administrative Agent otherwise consent, provided that no such
consent of the Borrower shall be required if an Event of Default has occurred
and is continuing;

                        (B) each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Lender's rights and
obligations under this Agreement;

                        (C) the parties to each assignment shall execute and
deliver to the Administrative Agent an Assignment and Assumption, together with
a processing and recordation fee of $10,000 payable by the assigning party; and

                        (D) the assignee, if it shall not be a Lender, shall
deliver to the Administrative Agent any information reasonably requested by the
Administrative Agent.

                  (iii) Subject to Section 13.04(b)(iv) and the acceptance and
recording thereof, from and after the effective date specified in each
Assignment and Assumption the assignee thereunder shall be a party hereto and,
to the extent of the interest assigned by such Assignment and Assumption, have
the rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such
Assignment and Assumption, be released from its obligations under this Agreement
(and, in the case of an Assignment and Assumption covering all of the assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall continue to be entitled to the benefits of Section
5.01, Section 5.02 and Section 13.03). Any assignment or transfer by a Lender of
rights or obligations under this Agreement that does not comply with this
Section 13.04 shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
Section 13.04(c).

                  (iv) The Administrative Agent, acting for this purpose as an
agent of the Borrower, shall maintain at one of its offices a copy of each
Assignment and Assumption delivered to it and a register for the recordation of
the names and addresses of the Lenders, and the Commitment of, and principal
amount of the Loans owing to, each Lender pursuant to the terms hereof from time
to time (the "Register"). The entries in the Register shall be conclusive, and
the Borrower, the Administrative Agent, and the Lender may treat each Person
whose name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary. The Register shall be available for inspection by the Borrower, and
any Lender, at any reasonable time and from time to time upon reasonable prior
notice. In connection with any changes to the Register, if necessary, the
Administrative Agent will reflect the revisions on Annex I and forward a copy of
such revised Annex I to the Borrower and each Lender.

                  (v) Upon its receipt of a duly completed Assignment and
Assumption executed by an assigning Lender and an assignee, the assignee's
providing any information reasonably requested by the Administrative, the
processing and recordation fee referred to in Section 13.04(b) and any written

                                       77
<PAGE>

consent to such assignment required by Section 13.04(b), the Administrative
Agent shall accept such Assignment and Assumption and record the information
contained therein in the Register. No assignment shall be effective for purposes
of this Agreement unless it has been recorded in the Register as provided in
this Section 13.04(b).

            (c) (i) Any Lender may, without the consent of the Borrower or the
Administrative Agent, sell participations to one or more banks or other entities
(a "Participant") in all or a portion of such Lender's rights and obligations
under this Agreement (including all or a portion of its Commitment and the Loans
owing to it); provided that (A) such Lender's obligations under this Agreement
shall remain unchanged, (B) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations and (C) the
Borrower, the Administrative Agent, and the other Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, modification or waiver
described in the proviso to Section 13.02 that affects such Participant. In
addition such agreement must provide that the Participant be bound by the
provisions of Section 13.03. Subject to Section 13.04(c)(ii), the Borrower
agrees that each Participant shall be entitled to the benefits of Section 5.01
and Section 5.02 to the same extent as if it were a Lender and had acquired its
interest by assignment pursuant to Section 13.04(b). To the extent permitted by
law, each Participant also shall be entitled to the benefits of Section 13.08 as
though it were a Lender, provided such Participant agrees to be subject to
Section 4.01(c) as though it were a Lender.

                  (ii) A Participant shall not be entitled to receive any
greater payment under Section 5.01 or Section 5.02 than the applicable Lender
would have been entitled to receive with respect to the participation sold to
such Participant, unless the sale of the participation to such Participant is
made with the Borrower's prior written consent.

            (d) Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations
of such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank, and this Section 13.04(d) shall not apply to any such
pledge or assignment of a security interest; provided that no such pledge or
assignment of a security interest shall release a Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender
as a party hereto.

      Section 13.05 Survival; Revival; Reinstatement.

            (a) All covenants, agreements, representations and warranties made
by the Borrower herein and in the certificates or other instruments delivered in
connection with or pursuant to this Agreement or any other Loan Document shall
be considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any
Loans, regardless of any investigation made by any such other party or on its
behalf and notwithstanding that the Administrative Agent or any Lender may have
had notice or knowledge of any Default or incorrect representation or warranty
at the time any credit is extended hereunder, and shall continue in full force
and effect as long as the principal of or any accrued interest on any Loan or
any fee or any other amount payable under this Agreement is outstanding and
unpaid and so long as the Commitments have not expired or terminated. The
provisions of Section 5.01, Section 5.02 and Section 13.03 and Article XII shall
survive and remain in full force and effect regardless of the consummation of
the transactions contemplated hereby, the repayment of the Loans, and the
Commitments or the termination of this Agreement, any other Loan Document or any
provision hereof or thereof.

            (b) To the extent that any payments on the Indebtedness or proceeds
of any collateral are subsequently invalidated, declared to be fraudulent or
preferential, set aside or required to be repaid to a trustee, debtor in
possession, receiver or other Person under any bankruptcy law, common law or
equitable cause, then to such extent, the Indebtedness so satisfied shall be
revived and continue as if such payment or proceeds had not been received and
the Administrative Agent's and the Lender's Liens, security interests, rights,
powers and remedies under this Agreement and each Loan Document shall continue
in full force and effect. In such event, each Loan Document shall be
automatically reinstated and the Borrower shall take such action as may be
reasonably requested by the Administrative Agent and the Lenders to effect such
reinstatement.

      Section 13.06 Counterparts; Integration; Effectiveness.

            (a) This Agreement may be executed in counterparts (and by different
parties hereto on different counterparts), each of which shall constitute an
original, but all of which when taken together shall constitute a single
contract.

            (b) This Agreement, the other Loan Documents and any separate letter
agreements with respect to fees payable to the Administrative Agent constitute
the entire contract among the parties relating to the subject matter hereof and
thereof and supersede any and all previous agreements and understandings, oral
or written, relating to the subject matter hereof and thereof. This Agreement
and the other Loan Documents represent the final agreement among the parties
hereto and thereto and may not be contradicted by evidence of prior,
contemporaneous or subsequent oral agreements of the parties. There are no
unwritten oral agreements between the parties.

            (c) Except as provided in Section 7.01, this Agreement shall become
effective when it shall have been executed by the Administrative Agent and when
the Administrative Agent shall have received counterparts hereof which, when
taken together, bear the signatures of each of the other parties hereto, and

                                       79
<PAGE>

thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart
of a signature page of this Agreement by telecopy shall be effective as delivery
of a manually executed counterpart of this Agreement.

      Section 13.07 Severability. Any provision of this Agreement or any other
Loan Document held to be invalid, illegal or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such invalidity,
illegality or unenforceability without affecting the validity, legality and
enforceability of the remaining provisions hereof or thereof; and the invalidity
of a particular provision in a particular jurisdiction shall not invalidate such
provision in any other jurisdiction.

      Section 13.08 Right of Setoff. If an Event of Default shall have occurred
and be continuing, each Lender and each of its Affiliates is hereby authorized
at any time and from time to time, to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other obligations (of whatsoever
kind, including, without limitations obligations under Swap Agreements) at any
time owing by such Lender or Affiliate to or for the credit or the account of
the Borrower or any Subsidiary against any of and all the obligations of the
Borrower or any Subsidiary owed to such Lender now or hereafter existing under
this Agreement or any other Loan Document, irrespective of whether or not such
Lender shall have made any demand under this Agreement or any other Loan
Document and although such obligations may be unmatured. The rights of each
Lender under this Section 13.08 are in addition to other rights and remedies
(including other rights of setoff) which such Lender or its Affiliates may have.

      Section 13.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS.

            (A) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK EXCEPT TO THE EXTENT THAT
UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CONTRACT FOR, CHARGE, RECEIVE,
RESERVE OR TAKE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH
LENDER IS LOCATED.

            (B) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN
DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED
STATES OF AMERICA LOCATED IN TEXAS, AND, BY EXECUTION AND DELIVERY OF THIS
AGREEMENT, EACH PARTY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY
LAW) IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION
OF THE AFORESAID COURTS. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION,
INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON
THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS
SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE A PARTY FROM
OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE HAVING
JURISDICTION.

            (C) EACH PARTY HEREBY (i) IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR
PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY

                                       80
<PAGE>

COUNTERCLAIM THEREIN; (ii) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT
PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH
LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES
OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (iii) CERTIFIES THAT NO PARTY
HERETO NOR ANY REPRESENTATIVE OR AGENT OF COUNSEL FOR ANY PARTY HERETO HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN
THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (iv)
ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE LOAN
DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 13.09.

      Section 13.10 Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

      Section 13.11 Confidentiality. Each of the Administrative Agent and the
Lender agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such Information and
instructed to keep such Information confidential), (b) to the extent requested
by any regulatory authority, (c) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process, (d) to any other party
to this Agreement or any other Loan Document, (e) in connection with the
exercise of any remedies hereunder or under any other Loan Document or any suit,
action or proceeding relating to this Agreement or any other Loan Document or
the enforcement of rights hereunder or thereunder, (f) subject to an agreement
containing provisions substantially the same as those of this Section 13.11, to
(i) any assignee of or Participant in, or any prospective assignee of or
Participant in, any of its rights or obligations under this Agreement or (ii)
any actual or prospective counterparty (or its advisors) to any Swap Agreement
relating to the Borrower and its obligations, (g) with the consent of the
Borrower or (h) to the extent such Information (i) becomes publicly available
other than as a result of a breach of this Section 13.11 or (ii) becomes
available to the Administrative Agent or any Lender on a non-confidential basis
from a source other than the Borrower. For the purposes of this Section 13.11,
"Information" means all information received from the Borrower or any Subsidiary
relating to the Borrower or any Subsidiary and their businesses, other than any
such information that is available to the Administrative Agent or any Lender on
a non-confidential basis prior to disclosure by the Borrower or a Subsidiary;
provided that, in the case of information received from the Borrower or any
Subsidiary after the date hereof, such information is clearly identified at the
time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section 13.11 shall be
considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such
Information as such Person would accord to its own confidential information.

      Section 13.12 Interest Rate Limitation. It is the intention of the parties
hereto that each Lender shall conform strictly to usury laws applicable to it.
Accordingly, if the transactions contemplated hereby would be usurious as to any
Lender under laws applicable to it (including the laws of the United States of

                                       81
<PAGE>

America the State of New York and the State of Texas or any other jurisdiction
whose laws may be mandatorily applicable to such Lender notwithstanding the
other provisions of this Agreement), then, in that event, notwithstanding
anything to the contrary in any of the Loan Documents or any agreement entered
into in connection with or as security for the Notes, it is agreed as follows:
(i) the aggregate of all consideration which constitutes interest under law
applicable to any Lender that is contracted for, taken, reserved, charged or
received by such Lender under any of the Loan Documents or agreements or
otherwise in connection with the Notes shall under no circumstances exceed the
maximum amount allowed by such applicable law, and any excess shall be canceled
automatically and if theretofore paid shall be credited by such Lender on the
principal amount of the Indebtedness (or, to the extent that the principal
amount of the Indebtedness shall have been or would thereby be paid in full,
refunded by such Lender to the Borrower); and (ii) in the event that the
maturity of the Notes is accelerated by reason of an election of the holder
thereof resulting from any Event of Default under this Agreement or otherwise,
or in the event of any required or permitted prepayment, then such consideration
that constitutes interest under law applicable to any Lender may never include
more than the maximum amount allowed by such applicable law, and excess
interest, if any, provided for in this Agreement or otherwise shall be canceled
automatically by such Lender as of the date of such acceleration or prepayment
and, if theretofore paid, shall be credited by such Lender on the principal
amount of the Indebtedness (or, to the extent that the principal amount of the
Indebtedness shall have been or would thereby be paid in full, refunded by such
Lender to the Borrower). All sums paid or agreed to be paid to any Lender for
the use, forbearance or detention of sums due hereunder shall, to the extent
permitted by law applicable to such Lender, be amortized, prorated, allocated
and spread throughout the stated term of the Loans evidenced by the Notes until
payment in full so that the rate or amount of interest on account of any Loans
hereunder does not exceed the maximum amount allowed by such applicable law. If
at any time and from time to time (i) the amount of interest payable to any
Lender on any date shall be computed at the Highest Lawful Rate applicable to
such Lender pursuant to this Section 13.12 and (ii) in respect of any subsequent
interest computation period the amount of interest otherwise payable to such
Lender would be less than the amount of interest payable to such Lender computed
at the Highest Lawful Rate applicable to such Lender, then the amount of
interest payable to such Lender in respect of such subsequent interest
computation period shall continue to be computed at the Highest Lawful Rate
applicable to such Lender until the total amount of interest payable to such
Lender shall equal the total amount of interest which would have been payable to
such Lender if the total amount of interest had been computed without giving
effect to this Section 13.12.

      Section 13.13 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO
SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS
OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS
AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS,
CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY
INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING
ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED
THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT

                                       82
<PAGE>

AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT
IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS
RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT
IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION
OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD
NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT
"CONSPICUOUS."

      Section 13.14 Collateral Matters; Swap Agreements. The benefit of the
Security Instruments and of the provisions of this Agreement relating to any
collateral securing the Indebtedness shall also extend to and be available to
those Lenders or their Affiliates which are counterparties to any Swap Agreement
with the Borrower or any of its Subsidiaries on a pro rata basis in respect of
any obligations of the Borrower or any of its Subsidiaries which arise under any
such Swap Agreement while such Person or its Affiliate is a Lender, but only
while such Person or its Affiliate is a Lender, including any Swap Agreements
between such Persons in existence prior to the date hereof. No Lender or any
Affiliate of a Lender shall have any voting rights under any Loan Document as a
result of the existence of obligations owed to it under any such Swap
Agreements.

      Section 13.15 No Third Party Beneficiaries. This Agreement, the other Loan
Documents, and the agreement of the Lenders to make Loans hereunder are solely
for the benefit of the Borrower, and no other Person (including, without
limitation, any Subsidiary of the Borrower, any obligor, contractor,
subcontractor, supplier or materialsman) shall have any rights, claims, remedies
or privileges hereunder or under any other Loan Document against the
Administrative Agent or any Lender for any reason whatsoever. There are no third
party beneficiaries.

      Section 13.16 Securitization. The Borrower hereby acknowledges that the
Lenders and their Affiliates may sell or securitize the Loans (a
"Securitization") through the pledge of the Loans as collateral security for
loans to the Lenders or their Affiliates or through the sale of the Loans or the
issuance of direct or indirect interests in the Loans, which loans to the
Lenders or their Affiliates or direct or indirect interests will be rated by
Moody's, S&P or one or more other rating agencies (the "Rating Agencies"). The
Borrower shall cooperate with the Lenders and their Affiliates to effect the
Securitization including, without limitation, by (a) amending this Agreement and
the other Loan Documents, and executing such additional documents, as reasonably
requested by the Lenders in connection with the Securitization, provided that
(i) any such amendment or additional documentation does not impose material
additional costs on the Borrower and (ii) any such amendment or additional
documentation does not materially adversely affect the rights, or materially
increase the obligations, of the Borrower under the Loan Documents or change or
affect in a manner adverse to the Borrower the financial terms of the Loans, (b)
providing such information as may be reasonably requested by the Lenders in
connection with the rating of the Loans or the Securitization, and (c) providing
in connection with any rating of the Loans a certificate (i) agreeing to
indemnify the Lenders and their Affiliates, any of the Rating Agencies, or any
party providing credit support or otherwise participating in the Securitization
(collectively, the "Securitization Parties") for any losses, claims, damages or

                                       83
<PAGE>

liabilities (the "Liabilities") to which the Lenders, their Affiliates or such
Securitization Parties may become subject insofar as the Liabilities arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact by Borrower or any Affiliate of Borrower contained in any Loan
Document or in any writing delivered by or on behalf of the Borrower or any
Affiliate of the Borrower to the Lenders in connection with any Loan Document or
arise out of or are based upon the omission or alleged omission by Borrower or
any Affiliate of Borrower to state therein a material fact required to be stated
therein, or necessary in order to make the statements therein, in light of the
circumstances under which they were made and as of the time made not misleading,
and such indemnity shall survive any transfer by the Lenders or their successors
or assigns of the Loans and (ii) agreeing to reimburse the Lenders and their
Affiliates for any legal or other expenses reasonably incurred by such Persons
in connection with defending the Liabilities.

      Section 13.17 USA Patriot Act Notice. Each Lender hereby notifies the
Borrower that pursuant to the requirements of the USA Patriot Act (Title III of
Pub. L. 107-56 (signed into law October 26, 2001)) (the "Patriot Act"), it is
required to obtain, verify and record information that identifies the Borrower,
which information includes the name and address of the Borrower and other
information that will allow such Lender to identify the Borrower in accordance
with the Act.

Lender on its books and, prior to any transfer of this Note, may be endorsed by
the Lender on the schedules attached hereto or any continuation thereof or on

and BERNARD NATIONAL SENIOR FUNDING, LTD. ("Bernard"), and DRAWBRIDGE SPECIAL
OPPORTUNITIES FUND LP ("Drawbridge" and with "Bernard" "Grantees" and, together
with any transferee of Warrants or Warrant Stock, the "Warrantholder").

                              W I T N E S S E T H:

Recitals:

      A. Reference is made to that certain Credit Agreement, dated as of
September 26, 2006, by and among DUNE ENERGY, INC., a Delaware corporation (the
"Borrower"), the lenders signatory thereto (the "Lenders"), and D.B. ZWIRN
SPECIAL OPPORTUNITIES FUND, L.P., as Administrative Agent (the "Credit
Agreement").

      B. As a consequence of the contractual relationship among the Company, the
Lenders and the Administrative Agent under the Credit Agreement, the Company has
and will continue to receive substantial benefits from the Lenders and the
Administrative Agent making advances to Company.

      C. The Company proposes to issue to Grantees as partial consideration for
the Lenders' and the Administrative Agent's entering into the Credit Agreement,
in the aggregate 500,000 common stock purchase warrants (the "Warrants") to
purchase 500,000 shares (the "Warrant Shares") which represents 0.84% of the
Company's common stock, par value $0.001 per share (the "Common Stock"), each
Warrant entitling the holder thereof to purchase one share of Common Stock.

      NOW, THEREFORE, in consideration of the mutual agreements herein
contained, the parties hereto agree as follows:

      Section 1. Issuance of Warrants; Execution and Delivery of Warrant
Certificates.

      1.1 Issuance of Warrants. The Company will issue and deliver the Warrants
to Grantee on the Effective Date as defined in the Credit Agreement (the
"Closing Date"). The aggregate number of Warrants to be issued and delivered to
the Grantees shall be 500,000. Such Warrants shall be evidenced by a certificate
(the "Warrant Certificate") which the Company will issue and deliver to Grantees
on the Closing Date. The Warrants shall vest on the Closing Date and shall be
exercisable on or after the Closing Date.

      1.2 Execution and Delivery of Warrant Certificates. Each original Warrant
Certificate issued shall be in substantially the form set forth in Appendix A
hereto and may have such letters, numbers, or other marks of identification or
designation and such legends or endorsements printed thereon as the officers of

                                       1
<PAGE>

the Company executing the same may approve (execution thereof to be conclusive
evidence of such approval) and as are not inconsistent with this Agreement, or
as may be required to comply with any law or with any rule or regulation made
pursuant thereto. The Warrant Certificates shall be executed on behalf of the
Company by its President or one of its Vice Presidents and by its Treasurer or
its Secretary.

      In case any officer of the Company who shall have signed any Warrant
Certificate shall cease to be an officer before the Warrant Certificate so
signed shall have been delivered by the Company, such Warrant Certificate may be
delivered notwithstanding that such person ceased to be an officer of the
Company, and any Warrant Certificate may be signed on behalf of the Company by
such person as, at the actual date of the execution of the Warrant Certificate,
shall be the proper officer of the Company, even if at the date of the execution
of this Agreement such person was no such officer.

      Section 2. Warrant Price, Manner of Exercise.

      2.1 Warrant Price, Term, Expiration and Notice. Each Warrant Certificate
shall entitle the Warrantholder, subject to the provisions thereof and of this
Agreement, to purchase from the Company one share of Common Stock for each of
the Warrants evidenced thereby at a price per share equal to $1.35 per share,
subject to adjustment as provided herein (the "Warrant Price"). The
Warrantholder may exercise any Warrants issued pursuant to this Agreement at any
time or from time to time, from the date hereof and prior to 5:00 p.m., New
York, New York time, on September 27, 2015 (the "Expiration Date"). If the
Expiration Date is not a Business Day, then this Warrant may be exercised on the
next succeeding Business Day. For purposes hereof, the term "Business Day" shall
mean any day other than a Saturday or a Sunday or a day on which commercial
banking institutions in the cities of New York, New York or Houston, Texas are
authorized or required by law to be closed, and provided that any reference to
"days" (unless Business Days are specified) shall mean calendar days.

      2.2 Manner of Exercise. The vested Warrants may be exercised by the
Warrantholder, in whole or in part, during normal business hours on any Business
Day by surrender of a Warrant Certificate, together with the form of Election to
Exercise included as Appendix B hereto (or a reasonable facsimile thereof) duly
executed by such Warrantholder, to the Company at its principal office,
accompanied by the required payment of the Warrant Price as then in effect, in
cash or other immediately available funds, or as provided in Section 2.3 below,
or a combination thereof.

      2.3 Cashless Exercise. The Warrantholder shall have the right to pay all
or a portion of the Warrant Price by making a "Cashless Exercise" pursuant to
this Section 2.3, in which case the Warrantholder shall not pay the Warrant
Price in cash and the number of shares of Common Stock otherwise issuable
pursuant to the Election to Exercise shall be reduced by the total number of
shares of Common Stock otherwise issuable to the Warrantholder multiplied by the
Warrant Price and divided by the Current Market Price per share of the Common
Stock on the date of the Election to Exercise, determined as provided in Section
3.1(d)(ii) of this Agreement.

                                       2
<PAGE>

      2.4 When Exercise Deemed Effected. Each exercise of Warrants pursuant to
this Agreement shall be deemed to have been effected immediately upon surrender
of such Warrants to the Company as provided in Section 2.2, and at such time,
the person or persons in whose name or names any certificate or certificates for
shares of Common Stock shall be issuable upon such exercise as provided in
Section 2.5 shall be deemed to have become the holder of record thereof.

      2.5 Delivery of Stock Certificates, etc. As soon as practicable after the
exercise of Warrants pursuant to this Agreement, in whole or in part, the
Company at its expense will cause

            (a) a certificate or certificates for the number of duly authorized,
validly issued, fully paid and nonassessable shares of Common Stock to which the
Warrantholder shall be entitled upon such exercise, to be issued in the name of
and delivered to such Warrantholder or such other name as shall be designated by
the Warrantholder in the Election of Exercise; and

            (b) in case less than all the Warrants represented by a Warrant
Certificate are exercised, a new Warrant Certificate of the same tenor and for
the number of Warrants not exercised to be registered in such name or names as
may be directed in writing by the Warrantholder and to be delivered to the
person entitled to receive such new Warrant Certificate.

      Section 3. Adjustment of Shares of Common Stock Purchasable and Warrant
Price.

      3.1 Antidilution Provision. So long as any Warrants are outstanding and
unexercised, in whole or in part:

            (a) if the Company shall pay a dividend in Common Stock or make any
other distribution in Common Stock on or with respect to its Common Stock, the
number of shares of Common Stock purchasable upon exercise of each Warrant
outstanding and unexercised at such time shall be increased by multiplying such
number of shares by a fraction, the denominator of which shall be the number of
shares of Common Stock outstanding at the close of business on the day
immediately preceding the date of such dividend or other distribution and the
numerator of which shall be the sum of such number of shares and the total
number of shares of Common Stock constituting such dividend or other
distribution, such increase to become effective immediately after the record
date of such dividend or other distribution;

            (b) in the event outstanding shares of Common Stock shall be
subdivided into a greater number of shares of Common Stock, the number of shares
of Common Stock purchasable upon exercise of each Warrant shall be
proportionately increased, and conversely, in case outstanding shares of Common
Stock shall be combined into a smaller number of shares of Common Stock, the
number of shares of Common Stock purchasable upon exercise of each Warrant shall
be proportionately decreased, such increase or decrease, as the case may be, to
become effective immediately after the effective date of such subdivision or
combination;

            (c) if the Company issues or distributes to all holders of Common
Stock (i) rights or warrants entitling them to subscribe for or purchase shares
of any class of capital stock of the Company or (ii) evidences of its
indebtedness, cash or other assets (including cash dividends but excluding stock

                                       3
<PAGE>

dividends referred to in subsection (a) above), the Company shall issue or
distribute to each Warrantholder such rights, warrants, evidences of
indebtedness, cash or other assets that such Warrantholder would have been
entitled to receive as a stockholder if such Warrantholder had exercised all of
its Warrants immediately prior thereto; and

            (d)

                  (i) if the Company shall sell or issue shares of Common Stock
            or securities convertible or exchangeable into shares of Common
            Stock or rights, options or warrants to purchase shares of Common
            Stock, or securities convertible or exchangeable into shares of
            Common Stock (collectively, the "Additional Shares"), at a price per
            share of Common Stock lower than the Current Market Price per share
            of Common Stock immediately prior to such sale or issuance, then the
            number of shares of Common Stock issuable upon exercise of the
            Warrant shall be adjusted to that number determined by multiplying
            the number of shares of Common Stock issuable upon exercise of the
            Warrant immediately prior to such adjustment by a fraction (y) the
            numerator of which shall be number of shares of Common Stock
            outstanding immediately prior to the issuance of such Additional
            Shares plus the number of such Additional Shares to be issued and
            (z) the denominator of which shall be the number of shares of Common
            Stock outstanding immediately prior to the issuance of such
            Additional Shares plus the number of shares of Common Stock which
            the aggregate consideration for the total number of such Additional
            Shares to be issued would purchase at the Warrant Price.
            Notwithstanding the foregoing, the provisions of this Section 3.1(d)
            shall not apply to any securities issued (A) in any of the
            transactions described in Sections 3.1(a), (b) or (c), or (B) upon
            exercise of this Warrant;

                  (ii) for the purposes of this Agreement, the "Current Market
            Price" shall mean the average price per share of the Company's
            Common Stock sold on all securities exchanges located in the United
            States on which the Common Stock may at the time be listed or traded
            (including, for this purpose, the NASDAQ National Market System or
            the NASDAQ SmallCap Market System), during the fifteen (15)
            consecutive trading days immediately preceding the date as of which
            the "Current Market Price" is to be determined, or, if there shall
            have been no sales on any such exchange on such day, the average of
            the highest bid and the lowest asked prices per share on all such
            exchanges at the end of such day, or if there is no such exchange on
            which the Common Stock is so listed or traded, the average of the
            high and low bid and asked prices per share of Common Stock on such
            fifteen (15) consecutive trading days in the domestic
            over-the-counter market as reported by the National Quotation Bureau
            Incorporated, or any similar successor organization. If at any time
            the Common Stock is not listed or traded on any United States
            securities exchange (including, for this purpose, the NASDAQ
            National Market System or the NASDAQ SmallCap Market System), or
            quoted in the domestic over-the-counter market, the "Current Market
            Price" shall be the fair market value per share of the Company's
            Common Stock as determined in good faith by the Board of Directors

                                       4
<PAGE>

            of the Company. Notwithstanding the preceding, if the Common Stock
            is not then listed or traded on any United States securities
            exchange, the NASDAQ National Market System or the NASDAQ SmallCap
            Market System, or quoted in the domestic over-the-counter market,
            and if the Warrantholder shall disagree with the determination made
            by the Board of Directors of the Current Market Price, it may so
            notify the Company and a reputable investment bank or appraiser
            mutually satisfactory to the Company and the Warrantholder shall be
            appointed to make such determination. If the Company and the
            Warrantholder are unable to agree within thirty (30) days regarding
            the investment bank or appraiser to make such determination, then
            Petrie Parkman & Co. shall be appointed to make such determination.
            All expenses of such investment bank or appraiser or Petrie Parkman
            & Co. shall be paid by the Warrantholder, unless the determination
            of Current Market Price by such investment bank or appraiser or
            Petrie Parkman & Co. is greater than 103% of the average Closing
            Prices or the determination thereof made by the Board of Directors
            as applicable, in which event the expenses of such investment bank
            or appraiser shall be paid by the Company. In either event, the
            determination made by the investment bank or appraiser or Petrie
            Parkman & Co. shall be the Current Market Price for all purposes of
            this Agreement;

                  (iii) if, at any time after any adjustment of the number of
            shares of Common Stock purchasable upon exercise of each Warrant
            pursuant to this Section 3.1(d), such rights, options, warrants or
            convertible or exchangeable securities shall expire or no longer be
            outstanding and shall not have been exercised for or converted or
            exchanged into Common Stock, such previous adjustment shall be
            rescinded and annulled and the Additional Shares which are deemed to
            have been issued by virtue of the computation made in connection
            with the adjustment so rescinded and annulled, shall no longer be
            deemed to have been issued by virtue of such computation. Thereupon,
            a recomputation shall be made to give effect to the expiration or
            non-exercise of, or failure to convert, such rights, options,
            warrants or convertible or exchangeable securities.

            (e) Consolidation, Merger, Sale of Assets, Reorganization, etc. If
the stockholders of the Company shall participate in a share exchange or if the
Company shall be a party to any transaction (including, without limitation, a
merger, consolidation, sale of all or substantially all of the Company's assets,
liquidation or recapitalization of the Common Stock) in which the previously
outstanding Common Stock shall be changed into or exchanged for different
securities of the Company or common stock or other securities of another
corporation, or interests in a non-corporate entity or other property (including
cash), or any combination of the foregoing (each such transaction being herein
called a "Transaction"), then the Company, in the case of the recapitalization
or liquidation of the Common Stock, or such other corporation or entity, in the
case of a share exchange, merger, consolidation or sale of all or substantially
all of the assets, shall make lawful and adequate provision so that, upon the
exercise thereof at any time on or after the consummation of the Transaction,
each Warrantholder shall be entitled to receive, and such Warrant shall
represent the right to receive, in lieu of the Common Stock, the securities or
other property (including cash) to which the Warrantholder would have been
entitled upon the consummation of the Transaction if such Warrantholder had
exercised such Warrant immediately prior thereto, subject to adjustment from and
after the consummation date as nearly equivalent as possible to the adjustments
provided for in Section 3.1.

      3.2 Statements on Warrant Certificates. The form of Warrant Certificate
need not be changed because of any adjustment made pursuant to this Section 3
and Warrant Certificates issued after such adjustment may state the same Warrant

                                       5
<PAGE>

Price and the same number of shares of Common Stock as are stated in the Warrant
Certificates initially issued pursuant to this Agreement.

      3.3 Accountants' Report as to Adjustments. In each case of any adjustment
or readjustment in the shares of Common Stock (or other securities) issuable
upon the exercise of the Warrants, the chief financial officer of the Company at
the Company's expense will promptly compute such adjustment or readjustment in
accordance with the terms of the Warrants and prepare a report setting forth
such adjustment or readjustment and showing in reasonable detail the method of
calculation thereof and the facts upon which such adjustment or readjustment is
based. If the Warrantholder so elects, Warrantholder can request that the
Company cause independent public accountants of recognized national standing
selected by the Company to verify such computations. The Company will forthwith
mail a copy of each such report to each Warrantholder. The Company will also
keep copies of all such reports at its principal office and will cause the same
to be available for inspection at such office during normal business hours by
any Warrantholder or any prospective purchaser of a Warrant designated by the
Warrantholder.

      3.4 Successive Transactions. The provisions of this Section 3 shall
similarly apply to successive share exchanges, consolidations, mergers, sales of
all or substantially all of the assets, or successive recapitalizations and
changes of shares of Common Stock.

            Section 4. Notices of Corporate Action. In the event of:

            (a) any offer to any holders of Common Stock of rights to subscribe
for or to purchase any Additional Shares or other securities, or

            (b) any taking by the Company of a record of the holders of any
class of securities for the purpose of determining the holders thereof who are
entitled to receive any dividend or other distribution, or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

            (c) any capital reorganization of the Company, any reclassification
or recapitalization of the capital stock of the Company or any consolidation or
merger involving the Company and any other person or entity, any share exchange
involving stockholders of the Company or any transfer of all or substantially
all the assets of the Company to any other person or entity, or

            (d) any voluntary or involuntary dissolution, liquidation or winding
up of the Company,

the Company will mail to each known Warrantholder a notice specifying (i) the
terms of such offer, and (ii) the date or expected date on which any such record
is to be taken for the purpose of such dividend, distribution or right, and the
amount and character of such dividend, distribution or right, and (iii) the date
or expected date on which any such reorganization, reclassification,
recapitalization, consolidation, merger, share exchange, transfer, dissolution,
liquidation or winding up is to take place and the time, if any such time is to
be fixed, as of which the holders of record of Common Stock shall be entitled to
exchange their shares of Common Stock for the securities or other property

                                       6
<PAGE>

deliverable upon such reorganization, reclassification, recapitalization,
consolidation, merger, share exchange, transfer, dissolution, liquidation or
winding up. Such notice shall be mailed at least 20 days prior to the date
therein specified.

      Section 5. Legend on Warrant Stock. Each certificate for Warrant Shares
initially issued upon exercise of this Warrant, unless at the time of exercise
such Warrant Shares are registered under the Securities Act of 1933, as amended
from time to time (the "Securities Act"), shall bear the following legend (and
any additional legend(s) required by any securities exchange upon which such
Warrant Stock may, at the time of such exercise, be listed) on the face thereof:

            "The Warrants represented by this certificate and the shares of
      common stock issued upon exercise hereof have not been registered under
      the Securities Act of 1933, as amended, or registered or qualified under
      applicable state securities laws. Such shares and or Warrants may not be
      offered, sold, transferred, pledged or hypothecated in the absence of an
      effective registration statement in effect with respect to the shares
      under such Act and registration or qualification under any applicable
      state securities laws or an opinion of counsel reasonably satisfactory to
      the Company that such registration or qualification is not required under
      applicable federal and state securities laws."

      Section 6. Reservation of Stock.

      6.1 Reservation of Stock. The Company will at all times reserve and keep
available, solely for issuance and delivery upon exercise of the Warrants, the
number of shares of Common Stock from time to time issuable upon exercise of all
Warrants at the time outstanding. All shares of Common Stock shall be duly
authorized and, when issued upon such exercise and payment of the Warrant Price,
shall be validly issued, fully paid and nonassessable with no liability on the
part of the holders thereof.

      Section 7. Other Provisions Relating to Rights and Obligations of Holders
of Warrant Certificates.

      7.1 Lost, Stolen, Mutilated or Destroyed Warrant Certificates. Upon
receipt by the Company of evidence reasonably satisfactory to it of the
ownership of and the loss, theft, destruction or mutilation of any Warrant
Certificate and of an indemnity from the Warrantholder reasonably satisfactory
to the Company and, in the case of mutilation, upon surrender of the Warrant
Certificate to the Company for cancellation, then, in the absence of notice to
the Company that such Warrant Certificate has been acquired by a bona fide
purchaser, the Company shall execute and deliver, in exchange for or in lieu of
the lost, stolen, destroyed or mutilated Warrant Certificate, a substitute
Warrant Certificate of the same tenor and evidencing a like number of Warrants.
Upon the issuance of any substitute Warrant Certificate under this Section 7.1,
the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses in connection therewith. Every substitute Warrant Certificate executed
and delivered pursuant to this Section 7.1 in lieu of any lost, stolen or
destroyed Warrant Certificate shall represent an additional contractual

                                       7
<PAGE>

obligation of the Company, whether or not the lost, stolen or destroyed Warrant
Certificate shall be at any time enforceable by anyone, and every holder thereof
shall be entitled to the benefits of this Warrant Agreement equally and
proportionately with any and all other Warrant Certificates duly executed and
delivered hereunder.

      7.2 Warrantholder May Enforce Rights. Notwithstanding any of the
provisions of this Warrant Agreement, any Warrantholder, without the consent of
the holder of any Common Stock or the holder of any other Warrant Certificate,
may, on its own behalf and for its own benefit, enforce, and may institute and
maintain any suit, action or proceeding against the Company suitable to enforce,
or otherwise in respect of, such Warrantholder's right to exercise the Warrants
evidenced by such Warrantholder's Warrant Certificate in the manner provided in
its Warrant Certificate and in this Agreement.

      Section 8. Registration Rights.

      8.1 Requested Registration.

            (a) Request for Registration. After the exercise of at least 167,500
Warrants for Common Stock, but in no event prior to March 31, 2007, each of
Bernard and Drawbridge (or their assignees) shall have the right upon written
request to the Company (the "Demand Registration"), on at least two separate
occasions to require the Company to effect a registration of such number of
Registrable Securities as the Warrantholders may elect. Upon receipt of such
notice, the Company will:

                  (i) promptly give written notice of the proposed registration
            to all other holders of Registrable Securities, which written notice
            shall include the name or names of the underwriter or underwriters
            to be employed; and

                  (ii) use its diligent good faith efforts to effect, as soon as
            practicable, such registration (including, without limitation, the
            filing of post-effective amendments, appropriate qualification under
            the applicable blue sky or other state securities laws and
            appropriate compliance with the Securities Act and any other
            governmental requirements or regulations) as may be so requested by
            any holder of Registrable Securities within five days after written
            notice is given by the Company and as would permit or facilitate the
            sale and distribution of all or such portion of the Registrable
            Securities so requested to be included in such registration;

provided that the Company shall not be obligated to take any action to effect
any such registration pursuant to this Section 8.1.1: (a) in any particular
jurisdiction in which the Company would be required to execute a general consent
to service of process, to register as a securities broker or dealer or to cause
any officer or employee of the Company to register as a salesman in effecting
such registration or (b) after the Company has effected two such registrations
pursuant to this Section 8.1.1which have been declared or ordered effective.

      Subject to the foregoing, the Company shall prepare and file a
registration statement covering the Registrable Securities so requested to be
registered as soon as reasonably practicable and in any event within 45 days
after such request is received.

                                       8
<PAGE>

      Notwithstanding the foregoing, the Company shall not be obligated to
effect a registration, qualification or compliance under this Section 8.1.1
starting with the date 60 days prior to the Company's good faith estimate of the
date of filing of, and ending on a date 180 days following the effective date
of, a registration statement pertaining to an underwritten public offering of
securities for the account of the Company, provided that the Company is actively
employing in good faith all reasonable efforts to cause such registration
statement to become effective and such registration statement becomes effective
within three months from the date of delivery to the Company of a written
request to effect such registration, qualification or compliance.

      (b) Selection of Underwriter. If any Demand Registration is an
underwritten offering, the holders of a majority of the Registrable Securities
to be included in such registration will select a managing underwriter or
managing underwriters of nationally recognized standing which shall be
reasonably acceptable to the Company. The Company shall (together with the
holders proposing to distribute their Registrable Securities through such
underwriting) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting in the manner set
forth above.

      The holders of Registrable Securities participating in a registration
under this Section 8.1 shall, to the extent required by the managing
underwriter(s), execute and deliver a custody agreement and power of attorney
with respect to the Registrable Securities to be registered (a "Custody
Agreement" and "Power of Attorney," respectively). The Custody Agreement and
Power of Attorney will provide, among other things, that the holders will
deliver to and deposit in custody with the custodian named therein a certificate
or certificates representing such Registrable Securities (duly endorsed in blank
by the registered owner or owners thereof or accompanied by duly executed stock
powers in blank) and irrevocably appoint said custodian and attorney-in-fact
with full power and authority to act under the Custody Agreement and Power of
Attorney, respectively, on such holder's behalf with respect to matters
specified therein, including the execution and delivery of an underwriting
agreement.

      Notwithstanding any of the other provisions of this Section 8.1, if the
managing underwriter determines and advises the Company that marketing factors
require a limitation of the number of shares to be underwritten, then all
holders of Registrable Securities that have previously elected to participate in
such registration shall be advised of the same, and the number of shares of
Registrable Securities that may be included in the registration and underwriting
shall be allocated among all such holders in proportion, as nearly as practical,
to the respective amounts of Registrable Securities that were proposed to be
sold by such holders. No Registrable Securities excluded from the underwriting
by reason of the underwriter's marketing limitation shall be in such
registration.

      If any holder of Registrable Securities disapproves of the terms of the
underwriting, such holder may elect to withdraw therefrom by written notice to
the Company and the managing underwriter and the other holders who have
previously elected to participate in the registration. The Registrable
Securities so withdrawn shall also be withdrawn from registration; provided that
if by the withdrawal of such Registrable Securities a greater number of
Registrable Securities held by other holders may be included in such
registration (up to a maximum of any limitation imposed by the underwriters),

                                       9
<PAGE>

then the Company shall offer to all holders who have included Registrable
Securities in the registration the right to include additional shares in the
same proportion used in effecting the limitation referred to above in this
Section 8.1.2.

      As used in this Agreement, the term "Registrable Securities" shall mean,
collectively, the shares of Common Stock acquired or to be acquired by the
Warrantholder upon exercise of the Warrants pursuant to this Agreement and any
shares of Common Stock or other securities issued with respect to such Common
Stock by way of a stock dividend or stock split or in connection with a
combination of shares, recapitalization, merger, consolidation, share exchange,
reorganization or otherwise; provided, however, that such Common Stock (or any
part thereof) or other securities shall cease to be Registrable Securities when
(i) a registration statement with respect to the disposition of such Common
Stock or other securities shall have become effective under the Securities Act
and such securities shall have been disposed of in accordance with the plan of
distribution set forth in such registration statement, (ii) and to the extent,
such Common Stock or other securities may be sold, without restrictions on
volume, pursuant to Rule 144 (or any successor provision) under the Securities
Act, (iii) an opinion of counsel, reasonably satisfactory to the Company and the
holders of Common Stock or other securities to which the opinion relates shall
have been delivered to the Company and such holders to the effect that the
subsequent disposition of such Common Stock or other securities may be made
pursuant to Rule 144(k) (or any successor provision) under the Securities Act,
or (iv) such Common Stock or other securities shall cease to be outstanding.

      8.2 Company Registration.

            (a) Right to Inclusion. If at any time (or from time to time) the
Company shall determine to register any of its securities in an underwritten
offering, either for its own account or the account of a holder of Registrable
Securities or any other holder of securities of the Company, other than (i) a
registration pursuant to Section 8.1 hereof, (ii) a registration relating solely
to employee benefit or stock option plans, (iii) a registration relating solely
to a transaction described in Rule145 under the Securities Act, (iv) a
transaction relating solely to an exchange offering, or (v) a transaction
relating solely to an acquisition of assets or property for securities, then the
Company will:

                  (i) promptly give to each holder of Registrable Securities
            written notice thereof (which shall include a list of the
            jurisdictions in which the Company intends to attempt to qualify the
            offer and sale of such securities under the applicable blue sky or
            other state securities laws); and

                  (ii) include in such registration (and any related
            qualification under blue sky laws or other compliance), and in any
            underwriting involved therein, all the Registrable Securities
            specified in any written request or requests by any holder received
            by the Company within 15 days after such written notice is given.

            (b) Underwriting. The right of any holder of Registrable Securities
to registration pursuant to Section 8.2 (a) shall be conditioned upon such
holder's participation in the underwriting and the inclusion of such holder's
Registrable Securities in the underwriting to the extent provided herein. All
holders proposing to distribute their Registrable Securities through such

                                       10
<PAGE>

underwriting shall enter into an underwriting agreement in customary form with
the underwriter or underwriters selected for such underwriting by the Company.
Such holders of Registrable Securities shall also execute and deliver, to the
extent required by the managing underwriter, a Custody Agreement and Power of
Attorney satisfactory to the Company with respect to the Registrable Securities
to be registered. The Custody Agreement and Power of Attorney will provide,
among other things, that such holders of Registrable Securities will deliver to
and deposit in custody with the custodian named therein a certificate or
certificates representing such Registrable Securities (duly endorsed in blank by
the registered owner or owners thereof or accompanied by duly executed stock
powers in blank) and irrevocably appoint said custodian and attorney-in-fact
with full power and authority to act under the Custody Agreement and Power of
Attorney, respectively, on the holder's behalf with respect to matters specified
therein, including the execution and delivery of an underwriting agreement.

      Notwithstanding any other provisions of this Section 8.2, if the managing
underwriter determines and advises the Company that marketing factors require a
limitation on the number of shares to be underwritten, the underwriter and the
Company may limit or exclude entirely the Registrable Securities to be included
in any registration and underwriting. In such event, the Company shall so advise
all holders of Registrable Securities that would otherwise be registered and
underwritten pursuant hereto, and the number of shares of Common Stock
(including the Registrable Securities) or other securities that may be included
in the registration and underwriting shall be allocated among all holders of
Registrable Securities and any other holders of Common Stock or other securities
requesting to be registered in proportion, as nearly as practicable, to the
respective amounts of Common Stock (including the Registrable Securities) or
other securities that were proposed to be sold by all holders of Registrable
Securities and holders of Common Stock or other securities entitled to
participate therein. No Registrable Securities excluded from the underwriting by
reason of the underwriter's marketing limitation shall be included in such
registration.

      If any holder of Registrable Securities disapproves of the terms of the
underwriting, such holder may elect to withdraw therefrom by written notice to
the Company and the managing underwriter(s). The Registrable Securities so
withdrawn shall also be withdrawn from registration; provided that if by the
withdrawal of such Registrable Securities a greater number of Registrable
Securities held by other holders may be included in such registration (up to the
maximum of any limitation imposed by the underwriters), then the Company shall
offer to all holders who have included Registrable Securities in the
registration the right to include additional shares in the same proportion used
in effecting the limitation referred to above in this Section 8.2.2. With
respect to any registration withdrawal by the Company pursuant to this Section
8.2.2, the Company shall have the right to withdraw such registration at any
time at its sole discretion without the consent or approval of any stockholder,
including the holders of Registrable Securities, in such registration.

      8.3 Expenses of Registration. All expenses incurred in connection with any
registration, qualification or compliance pursuant to this Section 8, including,
without limitation, all registration, filing and qualification fees, printing
expenses, escrow fees, fees and disbursements of counsel for the Company and
fees and expenses of accountants incidental to or required by such registration,

                                       11
<PAGE>

the fees and disbursements of one special counsel retained by the holders of
Registrable Securities covered by such registration, (but excluding
underwriters' fees, discount and commissions relating to the Registrable
Securities sold), shall be borne by the Company.

      8.4 Registration Procedures. In the case of such registration,
qualification or compliance effected by the Company pursuant to this Section 8,
the Company will keep each holder of Registrable Securities participating
therein advised in writing as to the initial filing of each registration,
qualification and compliance and as to the completion thereof. At its expense,
the Company will:

            (a) keep such registration, qualification or compliance pursuant to
Sections 8.1 or 8.2 effective for a period of 180 days or until the holders of
Registrable Securities participating therein have completed the distribution
described in the registration statement relating thereto, whichever occurs
first;

            (b) furnish such number of prospectuses and other documents incident
thereto as a holder of Registrable Securities participating therein from time to
time may reasonably request;

            (c) make available, upon reasonable notice and during business
hours, for inspection by the managing underwriter all financial and other
records, pertinent corporate documents, agreements and properties of the Company
as shall be reasonably necessary to enable such managing underwriter to exercise
its due diligence responsibilities, and cause the Company's officers, directors
and employees to supply all information reasonably requested by such managing
underwriter in connection with the registration;

            (d) during the period when the registration is required to be
effective, notify the holders of the Registrable Securities participating in the
registration of the happening of any event as a result of which the prospectus
included in the registration statement contains an untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein not misleading, and the Company will
forthwith prepare a supplement or amendment to such prospectus or take other
appropriate action so that, as thereafter delivered to the purchasers of such
Registrable Securities, such prospectus will not contain an untrue statement or
a material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading;

            (e) cause such Registrable Securities included in the registration
to be listed or authorized for trading on each securities exchange (including,
for this purpose, the NASDAQ National Market System or NASDAQ SmallCap System)
on which similar securities issued by the Company are then traded; provided that
the Company is eligible to do so under applicable listing requirements; and

            (f) otherwise use its best efforts to comply with all applicable
rules and regulations of the Securities and Exchange Commission (the
"Commission") and all of the terms and provisions of this Agreement.

      8.5 Related Registration Matters. The Company shall enter into an
underwriting agreement in connection with any registration subject to the
provisions of Sections 8.1 and 8.2 hereof, which agreement shall contain such

                                       12
<PAGE>

terms, provisions and agreements as are customary and appropriate for such
registration. In connection with the registration, to the extent not provided in
the underwriting agreement related to such registration, the Company also shall:

            (a) engage a bank or other company to act as transfer agent and
registrar for the Registrable Securities;

            (b) cause customary opinions of counsel, comfort letters of
accountants and other appropriate documents to be delivered by representatives
of the Company, which documents shall be addressed to the holders of Registrable
Securities participating in the offering in addition to the Underwriters or
other parties designated as addressees in such documents; and

            (c) as soon as practicable after the effective date of the
registration statement, and, in any event, within 16 months thereafter, make
"generally available to its stockholders" within the meaning of Rule 158 under
the Securities Act) an earnings statement (which need not be audited) complying
with Section 11(a) of the Securities Act and covering a period of at least 12
consecutive months beginning after the effective date of the registration
statement.

      8.6 Indemnification and Contribution.

            (a) In the event of registration of any of the Registrable
Securities under the Securities Act, the Company will indemnify and hold
harmless each holder of Registrable Securities included in such registration and
each of its directors and officers, each underwriter of such Registrable
Securities and each of its directors and officers, and each other person and
each of its directors and officers, if any, who controls such seller or
underwriter within the meaning of the Securities Act or the Securities Exchange
Act of 1934, as amended from time to time (the "Exchange Act"), or otherwise,
against any losses, claims, damages or liabilities (or actions in respect
thereof), joint or several, to which such seller, underwriter or controlling
person (or their respective directors and officers) may become subject under the
Securities Act, the Exchange Act or otherwise, insofar as such losses, claims,
damages or liabilities (and each of its directors and officers or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such Registrable Securities were registered under the Securities
Act, any preliminary prospectus or final prospectus contained in the
registration statement, or any amendment or supplement to such registration
statement, or arise out of or are based upon the omission or alleged omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading; and the Company will reimburse such seller,
underwriter and each such controlling person (and their respective directors and
officers) for any legal or any other expenses reasonably incurred by such
seller, underwriter or controlling person (and their respective directors and
officers) in connection with investigating or defending any such loss, claim,
damage, liability or action; provided that the Company will not have any
liability (and shall not be required to provide such indemnity and hold harmless
obligation) to the extent that any such loss, claim, damage or liability arises
out of or is based upon any untrue statement or omission made in such
registration statement, preliminary prospectus or prospectus, or any such
amendment or supplement, in reliance upon and in conformity with written

                                       13
<PAGE>

information furnished to the Company through an instrument duly executed by or
on behalf of such holder of Registrable Securities or underwriter specifically
for use in preparation thereof.

            (b) In the event of any registration of any of the Registrable
Securities under the Securities Act, each holder of Registrable Securities
included in such registration, severally and not jointly, will indemnify and
hold harmless the Company, each of its directors and officers and each
underwriter (if any) and each of its directors and officers and each person and
each of its directors and officers, if any, who controls the Company or any such
underwriter within the meaning of the Securities Act or the Exchange Act,
against losses, claims, damages or liabilities (or actions in respect thereof),
joint or several, to which the Company, such directors and officers, underwriter
or controlling person (or their respective directors and officers) may become
subject under the Securities Act, Exchange Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in any registration statement under which such
Registrable Securities were registered under the Securities Act, any preliminary
prospectus or final prospectus contained in the registration statement, or any
amendment or supplement to the registration statement, or arise out of or are
based upon any omission or alleged omission to state a material fact required to
be stated therein or necessary to make the statements therein not misleading, to
the extent, and only to the extent, that such untrue statement or omission was
made in reliance upon and in conformity with information furnished in writing to
the Company by or on behalf of such holder, specifically for use in connection
with the preparation of such registration statement, prospectus, amendment or
supplement; provided the liability of each holder of Registrable Securities
pursuant to this Section 8.6(b) shall be limited to the proceeds actually
received by such holder from the disposition of the Registrable Securities
disposed of by such holder pursuant to such registration.

            (c) Each party entitled to indemnification under this Section 8.6
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld, delayed or conditioned), and the Indemnified Party may participate in
such defense at such party's expense, and provided, further, that the failure of
any Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 8.6 (except and to the
extent the rights of the Indemnifying Party are materially prejudiced thereby).
After notice from the Indemnifying Party to the Indemnified Party of its
election to assume the defense of such claim or litigation, the Indemnifying
Party will not be liable to such Indemnified Party for any legal or other
expenses subsequently incurred by such Indemnified Party in connection with the
defense thereof other than reasonable costs of investigation so long as and to
the extent the Indemnifying Party continues to defend the Indemnified Party,
unless the Indemnifying Party, in the defense of any such claim or litigation
shall, except with the consent of each Indemnified Party, consent to entry of
any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

                                       14
<PAGE>

            (d) To the extent the Company after the date hereof shall agree to
provide for contribution in any written agreement entered into with the
stockholders of the Company if the indemnification obligations are otherwise
unavailable, then the Company shall provide such similar rights to the
Warrantholders in the registration of their shares.

      8.7 Information by Stockholders. Each holder of Registrable Securities
requesting to be included in any registration shall furnish to the Company such
information regarding such holder and the distribution proposed by such holder
as the Company may request in writing and as shall be required in connection
with any registration, qualification or compliance referred to in this Section
8.

      8.8 Sales Without Registration. If, at the time of any transfer of any
Registrable Securities, such Registrable Securities shall not be registered
under the Securities Act, the Company may require, as a condition of allowing
such transfer, that the holder of Registrable Securities or transferee furnish
to the Company an opinion of legal counsel satisfactory in form and substance to
the Company to the effect that such transfer may be made without registration
under the Securities Act; provided that nothing contained in this Section 8.8
shall relieve the Company from complying with any request for registration,
qualification or compliance made pursuant to the other provisions of this
Section 8.

      8.9 Rule 144. The Company covenants that it will file the reports required
to be filed by it under the 1933 Act and the Exchange Act and the rules and
regulations adopted by the Commission thereunder so long as necessary to permit
sales of Registrable Securities under Rule 144 under the 1933 Act, and it will
take such other action as any holder of Registrable Securities may reasonably
request, all to the extent required from time to time to enable such holder to
sell Registrable Securities without registration under the 1933 Act within the
limitation of the exemptions provided by (a) Rule 144 under the 1933 Act, as
such Rule may be amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the Commission. Upon the request of any holder
of Registrable Securities, the Company will deliver to such holder a written
statement as to whether it has complied with such requirements.

      8.10 Transfer of Registration Rights. The rights to cause the Company to
register Registrable Securities granted by the Company under Section 8.1 and the
right to participate in Company registration under Section 8.2 may be assigned
by any holder of Registrable Securities to a transferee or assignee of any
Registrable Securities (if such transfer or assignment of Registrable Securities
is permitted under Section 5), unless such transferee or assignee acquires such
Registrable Securities through a transaction or chain of transactions involving
a public offering or a sale effected pursuant to Rule 144; provided that the
holder shall give the Company written notice at the time of or within ten days
after said transfer, setting forth the name and address of said transferee or
assignee and identifying the Registrable Securities with respect to which such
registration rights are being assigned.

      8.11 Post-Effective Amendments. In connection with any registration
statement filed pursuant to this Section 8, the Company shall file any
post-effective amendment or amendments to the registration statement which may
be required under the Securities Act during the period set forth in Section
8.4(a).

                                       15
<PAGE>

      8.12 Cessation of Sale Activities. The Company shall notify each
participating holder of Registrable Securities during the period any
registration statement filed pursuant to this Section 8 is required to remain
effective, or at any time when a prospectus relating thereto is required to be
delivered under the Securities Act, of the happening of any event as a result of
which such registration statement or the prospectus contained therein, as then
in effect, includes an untrue statement of a material fact or omits to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading. Each participating holder agrees, upon receipt of such
notice, forthwith to cease making offers and sales of such securities pursuant
to such registration statement or deliveries of the prospectus contained therein
for any purpose and to return to the Company the copies of such prospectus not
theretofore delivered by such holder.

      8.13 Supplements. At a participating holder's request, the Company shall
prepare and furnish to such participating holder a reasonable number of copies
of any supplement to or amendment of such prospectus that may be necessary so
that, as thereafter delivered to the purchaser of any shares of Registrable
Securities, such prospectus shall not include any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statement therein not misleading in the light of the circumstances
then existing. The Company shall promptly notify each participating holder of
any stop order or similar proceeding initiated by state or Federal regulatory
bodies and use reasonable efforts to take all necessary steps expeditiously to
remove such stop order or similar proceeding.

      Section 9. Exchange and Transfer of Warrant Certificates.

      9.1 Exchange and Transfer of Warrant Certificates. Subject to the terms
contained in this Agreement, upon surrender at the principal office of the
Company, Warrant Certificates evidencing Warrants may be exchanged for Warrant
Certificates in other denominations evidencing such Warrants or the transfer
thereof may be registered in whole or in part; provided that such other Warrant
Certificates evidence the same aggregate number of Warrants as the Warrant
Certificates so surrendered. The Company shall keep the Warrant register in
which, subject to such reasonable regulations as it may prescribe, it shall
register Warrant Certificates upon surrender of such Warrant Certificates to the
Company at its principal office for exchange or registration of transfer,
properly endorsed or accompanied by appropriate instruments of registration of
transfer and written instructions for transfer, all in form satisfactory to the
Company. No service charge shall be made for any exchange or registration of
transfer of Warrant Certificates, but the Company may require payment of a sum
sufficient to cover any stamp or other tax or other governmental charge that may
be imposed in connection with any such exchange or registration of transfer.
Whenever any Warrant Certificates are so surrendered for exchange or
registration of transfer, the authorized officers of the Company shall execute
and deliver to the person or persons entitled thereto a Warrant Certificate or
Warrant Certificates duly authorized and executed by the Company, as so
requested. All Warrant Certificates issued upon any exchange or registration of
transfer of the Warrant Certificates shall be the valid obligations of the
Company, evidencing the same obligations, and entitled to the same benefits
under this Agreement, as the Warrant Certificate surrendered for such exchange
or registration of transfer.

                                       16
<PAGE>

      9.2 Treatment of Holders of Warrant Certificates. Every holder of a
Warrant Certificate, by accepting the same, consents and agrees with the Company
and with every subsequent holder of such Warrant Certificate that until the
transfer of the Warrant Certificate is registered on the Warrant register,
before such Warrant Certificate is surrendered for transfer pursuant to Section
9.1 hereof, the Company may treat the registered holder of a Warrant Certificate
as the absolute owner thereof for any purpose and as the person entitled to
exercise the rights represented by the Warrants evidenced thereby, any notice to
the contrary notwithstanding.

      9.3 Cancellation of Warrant Certificates. Any Warrant Certificate
surrendered for exchange, registration of transfer or transfer or exercise of
the Warrants evidenced thereby shall be surrendered to the Company, and all
Warrant Certificates surrendered and so delivered to the Company shall be
promptly cancelled by the Company and shall not be reissued and, except as
expressly permitted by this Agreement, no Warrant Certificate shall be issued
hereunder in exchange or in lieu thereof.
