Creditor, by acceptance thereof whether upon original issuance, transfer,
assignment or exchange, agrees to be bound by the provisions of this Agreement.

         Section 3. Certain Events of Defaults; Principal Payments. Second Lien
Creditor agrees as follows:

                  (a)      If any Default under the Senior Credit Agreement
occurs or exists, then if Senior Secured Creditor elects, in Senior Secured
Creditor's sole and absolute discretion to do so, Senior Secured Creditor may
send a stop payment notice as described in this Section 3(a) and (i) the rights
of Second Lien Creditor to receive any payments or other distributions with
respect to the Second Lien Debt shall be suspended from and after the date that
the Second Lien Creditor receives notice thereof from the Senior Secured
Creditor or a copy of the notice of such default from the Senior Secured
Creditor that Senior Secured Creditor sent to Borrower (each such notice being
hereinafter called a "Stop Payment Notice"), and (ii) except subsequent to a Buy
Back by the Second Lien Creditor of the Senior Secured Debt as set forth in
Section 3(b), no payment or distribution of any character, whether in cash,
securities or other property shall be made by any Loan Party, or received or
accepted by Second Lien Creditor, on account of the Second Lien Debt, or in
respect of the redemption, retirement, purchase or other acquisition thereof,
unless and until Second Lien Creditor shall have received notice from Senior
Secured Creditor that such default shall have been cured or waived.

                  (b)      In the event that the Senior Secured Creditor sends a
Stop Payment Notice as described hereinabove to the Second Lien Creditor, the
Second Lien Creditor may, in Second Lien Creditor's sole and absolute
discretion, send a notice to buy the Senior Secured Debt and Liens securing same
from the Senior Secured Creditor upon the following terms and conditions: (i)
the Second Lien Creditor shall give written notice to the Senior Secured
Creditor, informing the Senior Secured Creditor of the Second Lien Creditor's
election to buy the Senior Secured Debt and Liens securing same related thereto
(the purchase hereinafter called a "Buy Back" and any such notice being
hereinafter called a "Buy Back Notice"), (ii) the Second Lien Creditor shall
have forty-five (45) days from the date of the Stop Payment Notice to purchase
the Senior Secured Debt for an amount equal to the outstanding Senior Secured
Debt (including, without limitation, principal, interest, fees, and expenses
(reimbursable under the Senior Loan Documents) outstanding on the date of the
purchase), (iii) said Buy Back shall not occur (at Senior Secured Creditor's
election) if the Default that precipitated the Stop Payment Notice has been
waived or cured prior to the consummation of the Buy Back, and (iv) upon receipt
of

                                      -4-
<PAGE>

payment of all of the Senior Secured Debt as described above, the Senior Secured
Creditor will execute an assignment of the Senior Secured Debt and Liens
securing same to the Second Lien Creditor without recourse and without
representation or warranty (either express or implied), other than to the effect
that the Senior Secured Creditor at the closing of the Buy Back has not sold or
assigned the Second Lien Debt and Liens securing same and the amount of the
Senior Secured Debt. Contemporaneously with the consummation of the Buy Back,
the Borrower and the Guarantors shall acknowledge such assignment and shall do
all things necessary to give full force and effect thereto.

                  (c)      Notwithstanding anything to the contrary contained
above in Sections 3(a) and 3(b), (i) Borrower may pay and Second Lien Creditor
may take and retain any regularly scheduled interest (but not principal) payment
on the Second Lien Debt received by Second Lien Creditor before receipt by
Second Lien Creditor of a Stop Payment Notice, and (ii) Borrower shall be
entitled to resume the making of any payments otherwise prohibited under this
Section 3, including any payments previously suspended, at such time as Second
Lien Creditor shall have received notice from Senior Secured Creditor that the
default giving rise to such prohibition shall have been cured or waived.

                  (d)      Notwithstanding any other provision in this entire
Agreement to the contrary, except if Second Lien Creditor exercises and
completes Buy Back under Section 3(b) or 5(b) in this Agreement, in no event
shall any Loan Party pay or Second Lien Creditor take and retain any payment of
principal on the Second Lien Debt until the Senior Secured Debt shall have been
paid in full in cash.

         Section 4. Events of Insolvency, etc. Second Lien Creditor agrees that,
in the event and during the continuation of any Proceeding, until all Senior
Secured Debt shall first have been finally and irrevocably paid in full, in
cash, any payment or distribution in any such Proceeding of any kind or
character, whether in cash, securities or other property which would otherwise
(but for this Agreement) be payable or deliverable in respect of any Second Lien
Debt shall, unless otherwise agreed in writing, signed by the Senior Secured
Creditor and the Second Lien Creditor, be paid or delivered by the person making
such distribution or payment, whether a trustee in bankruptcy, receiver,
assignee for the benefit of creditors, liquidating trustee or agent, or
otherwise, directly to the Senior Secured Creditor, for application in payment
of the Senior Secured Debt in accordance with the priorities then existing among
such holders, to the extent necessary to pay in full all Senior Secured Debt
then remaining unpaid, after giving effect to any concurrent payment or
distribution to the holders of Senior Secured Debt. Should Second Lien Creditor
receive any such payment, it will promptly turn over such payment to Senior
Secured Creditor.

         Section 5. Standstill. (a) Second Lien Creditor agrees to promptly send
to Senior Secured Creditor a notice of any default that occurs and is continuing
under the Second Lien Loan Documents and further agrees that Second Lien
Creditor shall not accelerate any of the amounts due with respect to the Second
Lien Debt or exercise any rights or remedies or take any enforcement action
available upon the occurrence of a default or an event of default or otherwise
under the Second Lien Loan Documents or take any action toward the collection of
any Second Lien Debt until the earliest of (i) 180 days following receipt by
Senior Secured Creditor of a written Enforcement Notice from Second Lien
Creditor stating that it is the formal Enforcement

                                      -5-
<PAGE>

Notice required under this Agreement, (ii) the date Senior Secured Creditor
accelerates the maturity of the Senior Secured Debt or the date Senior Secured
Creditor exercises any foreclosure remedies or proceedings available to it upon
a default or event of default with respect to the Senior Secured Debt, (iii) the
occurrence of a Proceeding, or (iv) all of the Senior Secured Debt shall have
been paid in full in cash. The failure to make a payment of principal of,
interest on, or fees, costs or expenses relative to any of the Second Lien Debt
by reason of any provision of this Agreement shall not be construed as
preventing the occurrence of a default or event of default with respect to such
Second Lien Debt as a result of such failure. After the earliest to occur of the
events described in clauses (i) through (iv) above, Second Lien Creditor shall
be permitted, to the extent it is authorized to do so under the Second Lien Loan
Documents and applicable law and subject to the provisions of Section 3, to
accelerate the maturity and demand payment of the Second Lien Debt, commence
suit against any Loan Party, obtain a judgment lien, and otherwise seek to
collect the Second Lien Debt and enforce the Second Lien Loan Documents;
provided, however, that Second Lien Creditor's right to take any action in
respect of any of the Collateral or Proceeds shall be limited as set forth in
Section 9 hereof.

                  (b)      In the event that the Second Lien Creditor sends a
notice of default as described in subsection (a) above to the Senior Secured
Creditor, the Second Lien Creditor may, in the Second Lien Creditor's sole and
absolute discretion, buy the Debt and Liens securing same from the Senior
Secured Creditor upon the following terms and conditions: (i) the Second Lien
Creditor shall give a written notice to the Senior Secured Creditor, informing
the Senior Secured Creditor of the Second Lien Creditor's election to buy the
Senior Secured Debt and Liens securing same related thereto (the purchase
hereinafter called a "Standstill Buyback" and such notice being hereinafter
called a "Standstill Buy Back Notice"), (ii) the Second Lien Creditor may,
within forty-five (45) days of the date of the Standstill Buy Back Notice, and
so long as the default that gave rise to such notice is continuing, purchase the
Senior Secured Debt for an amount equal to the outstanding Senior Secured Debt
(including, without limitation, principal, interest, fees, and expenses
outstanding on the date of the purchase) and (iii) upon receipt of the payment
as described above, the Senior Secured Creditor will execute an assignment of
the Senior Secured Debt and Liens securing same to the Second Lien Creditor
without recourse and without representation or warranty (either express or
implied), other than to the effect that the Senior Secured Creditor at the
closing of the Standstill Buy Back has not otherwise sold or assigned the Senior
Secured Debt and Liens securing same and the amount of the Senior Secured Debt.
Contemporaneously with the consummation of the Standstill Buy Back, the Borrower
and the Guarantors shall acknowledge such assignment and shall do all things
necessary to give full force and effect thereto.

         Section 6. Payments Notwithstanding. No payment or distribution of any
character, whether in cash, securities or other property to which Second Lien
Creditor would have been entitled except for the provisions of this Agreement
and that shall have been made to or for the account of Senior Secured Creditor
shall, as between each Loan Party and its creditors (other than Senior Secured
Creditor), be deemed to be a payment or distribution by such Loan Party to or
for the account of Senior Secured Creditor, and from and after the payment in
full in cash of all Senior Secured Debt, Second Lien Creditor shall be
subrogated to all rights of Senior Secured Creditor to receive any further
payments or distribution applicable to the Senior Secured Debt until the
principal of and interest on the Second Lien Debt shall be paid in full in cash,
and no

                                      -6-
<PAGE>

such payment or distribution made pursuant to such rights of subrogation to
Second Lien Creditor that otherwise would be payable or distributable to or for
the account of Senior Secured Creditor shall, as between each Loan Party and its
creditors (other than Second Lien Creditor), be deemed to be a payment or
distribution by such Loan Party to Second Lien Creditor or on account of the
Second Lien Debt.

         Section 7. No Prejudice or Impairment. The provisions of this Agreement
are solely for the purposes of defining the relative rights of Senior Secured
Creditor, on the one hand and Second Lien Creditor, on the other hand. Senior
Secured Creditor shall not be prejudiced in the right to enforce the terms of
this Agreement by any act or failure to act by any Loan Party or anyone in
custody of its assets or property. Nothing herein shall impair, as between each
Loan Party and Second Lien Creditor, the obligation of such Loan Party, which is
unconditional and absolute, to pay to Second Lien Creditor the principal of and
interest on the Second Lien Debt as and when the same shall become due in
accordance with their terms, nor shall anything herein prevent Second Lien
Creditor from exercising all remedies otherwise permitted by applicable law upon
default under the Second Lien Loan Documents, subject, however, to the
provisions of this Agreement and the rights of Senior Secured Creditor to the
extent provided herein. Second Lien Creditor shall not at any time be charged
with knowledge of the existence of any facts which would prohibit the making of
any payment to Second Lien Creditor or, except as otherwise provided in Section
5, the taking of any other action under this Agreement unless and until Second
Lien Creditor shall have received written notice from Senior Secured Creditor
and, prior to the receipt of any such notice, Second Lien Creditor shall be
entitled to assume conclusively that no such facts exist.

         Section 8. Turnover of Payments. If any payment, distribution,
security, or the proceeds of any thereof, shall be collected or received by
Second Lien Creditor in contravention of any of the terms of this Agreement and
prior to the irrevocable payment in full in cash of Senior Secured Debt at the
time outstanding, the holder thereof will forthwith deliver such payment,
distribution, security or proceeds to Senior Secured Creditor and, until so
delivered, the same shall be held in trust by such holder as the property of
Senior Secured Creditor.

         Section 9. Priorities Regarding Collateral. Any and every Lien and
security interest in the Collateral (whether now or hereafter existing) in favor
of or held for the benefit of Senior Secured Creditor has and shall have
priority over any Lien or security interest that Second Lien Creditor now has or
may hereafter acquire in the Collateral notwithstanding any statement or
provision contained in the Second Lien Loan Documents or otherwise to the
contrary, and irrespective of whether the Senior Lender has a perfected security
interest in the Collateral or not, and irrespective of the time or order of
obtaining a judgment or filing or recording of financing statements, deeds of
trust, mortgages or other notices of security interests, Liens or assignments
granted pursuant thereto, and irrespective of anything contained in any filing
or agreement to which any party hereto or its respective successors and assigns
may now or hereafter be a party, and irrespective of the ordinary rules for
determining priorities under the UCC or under any other law governing the
relative priorities of secured and lien creditors. Second Lien Creditor shall be
entitled to rely upon any final, non-appealable order or decree made by any
court of competent jurisdiction in which proceedings are pending, or a
certificate of the liquidating trustee or other person making any distribution
to Second Lien Creditor, for the

                                      -7-
<PAGE>

purpose of ascertaining the persons entitled to participate in such
distribution, the Senior Secured Creditor and the holders of other debt of
Borrowers, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Agreement;
provided, however, that to give effect to this provision the Senior Secured
Creditor shall have filed all financing statements in the manner and at the
locations required to perfect its security interests in the Collateral prior to
the close of business, five (5) business days immediately following the Closing
Date and shall have promptly notified the Collateral Agent to that effect.

         Notwithstanding anything contained in this Section 9 or elsewhere in
this Agreement, during the term of this Agreement: (a) in no event shall Second
Lien Creditor seek to attach, garnish, levy or execute upon or otherwise seek to
enforce any Lien upon assets of any Loan Party, and Second Lien Creditor shall
be barred from taking any such enforcement action with respect to any of the
Collateral or Proceeds; and (b) in no event shall Second Lien Creditor seek or
take a Lien on any assets of any of the Loan Parties unless Senior Secured
Creditor also has a Lien on such assets that is superior to any Lien that Second
Lien Creditor has covering such assets and is made subject to the terms of this
Agreement. Should any such Liens exist, either now or in the future, by this
document they shall be deemed to be fully subordinated to the Liens of the
Senior Secured Creditor pursuant to the terms hereof and any funds received by
the Second Lien Creditor with respect to such assets shall be held in trust for
the benefit of the Senior Secured Creditor. Senior Secured Creditor agrees that,
upon payment in full of the Senior Secured Debt and upon termination of the
security interests and Liens securing the Senior Secured Debt, the Senior
Secured Creditor shall deliver all Collateral in its possession or under its
control to Second Lien Creditor.

         Nothing in this Section 9 or elsewhere in this Agreement is intended
(and shall not be construed) to permit a court or other authority to disregard
or modify in its discretion payment or Lien priorities set forth in this
Agreement, but rather is intended simply to indicate that Second Lien Creditor
may rely on the interpretation of a court of competent jurisdiction regarding
interpretation of this Agreement and the appropriate payment priorities in
accordance with this Agreement.

         Section 10. Benefit of Agreement, Amendments of Certain Documents, etc.
This Agreement shall constitute a continuing offer to all persons who, in
reliance upon such provisions, become a Senior Secured Creditor, and such
provisions are made for the benefit of each Senior Secured Creditor and each of
them may enforce such provisions. Neither Senior Secured Creditor nor Second
Lien Creditor shall have any obligation to preserve rights in the Collateral
against any prior parties or to marshal any of the Collateral for the benefit of
any person. No failure to exercise, and no delay in exercising on the part of
any party hereto, any right, power or privilege under this Agreement shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, power or privilege under this Agreement preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The
rights and remedies provided in this Agreement are cumulative and shall not be
exclusive of any rights or remedies provided by law. Any agreements, promissory
notes, documents or instruments which at anytime evidence the Second Lien Debt
or any part thereof shall be marked with a conspicuous legend in bold print
stating that payment hereunder is subject to the terms and

                                      -8-
<PAGE>

provisions of this Agreement. In no event shall any Second Lien Creditor (i)
initiate or prosecute or encourage any other person to initiate or prosecute any
claim, action or other proceeding challenging the enforceability of the Senior
Secured Debt or any Liens and security interests securing the Senior Secured
Debt or (ii) contest the enforceability of this Agreement.

         Section 11. Senior Secured Creditor's Freedom of Dealing. Second Lien
Creditor agrees, with respect to the Senior Secured Debt and any and all
Collateral therefor and guaranties thereof, that each Loan Party and Senior
Secured Creditor may agree to increase the amount of the Senior Secured Debt
provided that the Borrowing Base shall not be increased above Sixty-Five Million
and no/100 Dollars ($65,000,000.00) without the prior written consent of Second
Lien Creditor) or (except as expressly limited by Section 12(b)) change the
amount, manner, place or terms of payment or otherwise modify the terms of any
of the Senior Secured Debt, and (except as expressly limited by Section 12(b))
Senior Secured Creditor may grant extensions of the time of payment or
performance to and make compromises, including sales, exchanges and releases of
Collateral or guaranties, and settlements with any Loan Party and all other
persons, and may exercise or refrain from exercising any rights against any Loan
Party and others, in each case without the consent of Second Lien Creditor and
without affecting the agreements of the Second Lien Creditor contained in this
Agreement. No compromise, alteration, amendment, modification, extension,
renewal or other change of, or waiver, consent or other action in respect of any
liabilities or obligations under or in respect of any of the terms, covenants,
or conditions of any Senior Loan Document, whether or not in accordance with the
provisions of any applicable document, shall in any way alter or affect any of
the provisions of this Agreement.

         Section 12. Modification and Assignment of Debt.

                  (a)      Modification of Second Lien Debt. Second Lien
Creditor agrees that it will not: (i) amend or modify any of the Second Lien
Loan Documents to add any covenant thereto; or (ii) amend or otherwise change
the terms of any Second Lien Debt or accept any payment consistent with an
amendment or change thereto, if the effect of such amendment or change is to
increase the interest rate on such Second Lien Debt, change any date on which a
payment of principal or interest is due thereon to an earlier date or increase
the amount of any such payment, change any default or condition to a default
with respect to such Second Lien Debt, change the redemption provisions thereof
to an earlier date, take any Collateral or make any other change which, together
with all other amendments or changes made, increase materially the obligations
of the obligor or confer additional rights on the holder of such Second Lien
Debt that would be adverse to any Loan Party or Senior Secured Creditor.
Notwithstanding any other provision in this Agreement to the contrary, Second
Lien Creditor represents, warrants, and agrees that the Second Lien Loan
Documents do not and will not, without the prior written consent of Senior
Secured Creditor (1) provide for any principal amortization of the Second Lien
Debt prior to the maturity of the Senior Secured Debt, (2) include financial
covenants or events of default which are not included in the Senior Loan
Documents and any such included financial covenants or events of default shall
be no more stringent from those contained in the Senior Loan Documents, as
determined by Senior Secured Creditor, (3) mature less than twelve (12) months
after the maturity of the Senior Secured Debt, and (4) have interest payments
more than monthly.

                  (b)      Assignment of Senior Secured Debt and/or Second Lien
Debt. Neither Senior Secured Creditor nor Second Lien Creditor will sell,
transfer, pledge, assign, hypothecate

                                      -9-
<PAGE>

or otherwise dispose of any or all of the Senior Secured Debt or Second Lien
Debt, as the case may be, to any person other than a person who executes a
counterpart of this Agreement (or in the case of a Senior Secured Creditor
agrees to be bound hereto in the assignment and acceptance delivered pursuant to
the Senior Credit Agreement) and becomes a party hereto, thereby succeeding to
the rights and agreeing to be bound by all of the obligations of such Senior
Secured Creditor or Second Lien Creditor hereunder.

         Section 13. Reservation of Security Interests as Against Third Parties.
Nothing contained in this Agreement is intended to affect or limit in any way
the security interests and/or Liens Second Lien Creditor and Senior Secured
Creditor has in or on any or all of the property and assets of any Loan Party,
whether tangible or intangible, insofar as any Loan Party and third parties are
concerned. Second Lien Creditor and Senior Secured Creditor hereto specifically
reserve all respective security interests and/or Liens and rights to assert such
security interests and/or Liens as against any Loan Party and third parties.

         Section 14. Priority of Security Interests. Irrespective of (a) the
time, order, manner or method of creation, attachment or perfection of the
respective security interests and/or Liens granted to Second Lien Creditor or
Senior Secured Creditor in or on any or all of the property or assets of
Borrower, (b) the time or manner of the filing, failure to file, or the filing
in the wrong place of their respective financing statements, (c) whether Second
Lien Creditor or Senior Secured Creditor or any bailee or agent thereof holds
possession of any or all of the property or assets of Borrower, (d) the dating,
execution or delivery of any agreement, document or instrument granting Second
Lien Creditor or Senior Secured Creditor security interests and/or Liens in or
on any or all of the property or assets of Borrower, (e) the giving or failure
to give notice of the acquisition or expected acquisition of any purchase money
or other security interests, and (f) any provision of the UCC or any other
applicable law to the contrary, any and all security interests, Liens, rights
and interests of Second Lien Creditor, whether now or hereafter arising and
howsoever existing, in or on any or all of the Collateral shall be and hereby
are subordinated to any and all security interests, Liens, rights and interests
of Senior Secured Creditor in and to the Collateral. For purposes of the
foregoing allocation of priorities, any claim of a right of setoff shall be
treated in all respects as a security interest and no claimed right of setoff
shall be asserted to defeat or diminish the rights or priorities provided for
herein.

         Section 15. Release of Senior Secured Creditor Collateral. Second Lien
Creditor agrees that any collection, sale or disposition of any or all of the
Collateral by Senior Secured Creditor (whether pursuant to the UCC or otherwise)
shall be free and clear of any and all security interests, Liens, claims, and/or
rights of Second Lien Creditor in such Collateral. At the request of Senior
Secured Creditor, Second Lien Creditor shall promptly provide Senior Secured
Creditor with any necessary or appropriate releases to permit the collection,
sale or other disposition of any or all of the Collateral free and clear of
Second Lien Creditor's security interests and Liens, so long as the proceeds
thereof are applied, first, to the payment of amounts payable with respect to
the Senior Secured Debt until the Senior Secured Debt is fully repaid and
second, to the payment of amounts payable with respect to the Second Lien Debt
to the extent the same is secured by Collateral.. In addition, at the request of
Senior Secured Creditor, Second Lien Creditor shall promptly release, at the
consummation of the sale or other disposition of any Collateral, any and all
security interests, Liens, claims and/or rights which it may have on or in

                                      -10-
<PAGE>

the applicable Collateral to facilitate the collection, sale or other
disposition of such Collateral by Borrower so long as the proceeds thereof are
applied first to the payment of the Senior Secured Debt and any excess is then
applied to the payment of the Second Lien Debt to the extent the same is secured
by the Collateral.

         Section 16. Non-avoidability and Perfection. The subordinations and
relative priority arrangements set forth in this Agreement are applicable
regardless of whether the security interest and/or Lien to which another
security interest and/or Lien is subordinated is not perfected or is voidable
for any reason.

         Section 17. Insurance Proceeds. In the event of the occurrence of any
casualty with respect to any of the Collateral, Second Lien Creditor and Senior
Secured Creditor agree that Senior Secured Creditor shall have the sole and
exclusive right to adjust, compromise or settle any such loss with the insurer
thereof, and to collect and receive the proceeds from such insurer to the extent
of the Senior Secured Debt until the Senior Secured Debt has been paid in full.
Any insurer shall be fully protected if it acts in reliance on the provisions of
this paragraph.

         Section 18. Assignment of Second Lien Debt. Second Lien Creditor
represents and warrants to Senior Secured Creditor that it has not previously
assigned any interest in any of the Second Lien Debt, that no other party owns
an interest in any of the Second Lien Debt other than Second Lien Creditor
(whether as joint holders of the Second Lien Debt, as participants or otherwise)
and that the entire Second Lien Debt is owed only to Second Lien Creditor.
Second Lien Creditor covenants and agrees with Senior Secured Creditor that the
entire Second Lien Debt shall continue to be owing only to Second Lien Creditor,
unless such indebtedness is assigned expressly subject to the terms, provisions
and conditions of this Agreement, the assignee of such indebtedness agrees in
writing to be bound by the terms, provisions and conditions of this Agreement,
and Second Lien Creditor shall have delivered such executed assignment and
assumption agreements to Senior Secured Creditor.

         Section 19. Amendment of Senior Secured Debt; Release of Collateral.
Senior Secured Creditor may at any time and from time to time (a) enter into
such agreements with Borrower as Senior Secured Creditor may deem proper (i)
increasing or decreasing the principal amount of, extending the time of payment
of and/or renewing or otherwise amending or altering the terms (including,
without limitation, the interest rates) of any or all of the Senior Secured
Debt, (ii) increase or decrease the Borrowing Base (provided that such amount
shall not be increased above Sixty-Five Million and no/100 Dollars
($65,000,000.00) without the prior written consent of Second Lien Creditor),
and/or (iii) amending, modifying or otherwise altering the terms of the Senior
Loan Documents and (b) exchange, sell, release, surrender or otherwise deal with
any or all of the Collateral, all without in any way compromising or affecting
this Agreement.

         Section 20. Reliance by Senior Secured Creditor; Waiver of Notices; No
Representations by Senior Secured Creditor; Management of Credit Facilities by
Senior Secured Creditor. All of the Senior Secured Debt shall be deemed to have
been made or incurred in reliance upon this Agreement. Second Lien Creditor
expressly waives all notice of the acceptance by Senior Secured Creditor of the
provisions of this Agreement and all other notices not specifically required
pursuant to the terms of this Agreement. Second Lien Creditor agrees

                                      -11-
<PAGE>

that neither Senior Secured Creditor nor its officers, directors, employees, or
attorneys have made any representation or warranty with respect to the due
execution, legality, validity, completeness or enforceability of any of the
Senior Loan Documents, the perfection or priority of any security interest or
Lien or description of, or title to, or the value of any of the Collateral
securing any or all of the Senior Secured Debt or the Second Lien Debt, or the
collectibility of any of the Senior Secured Debt or the Second Lien Debt. Senior
Secured Creditor shall be entitled to manage and supervise its credit facilities
with Borrower in accordance with applicable law and its usual business
practices, modified from time to time as it deems appropriate under the
circumstances, without regard to the existence of any rights that Second Lien
Creditor may have now or hereafter in or to any of the property or assets of
Borrower or any other Loan Party, and Senior Secured Creditor shall have no
liability to Second Lien Creditor for any loss, claim or damage allegedly
suffered by Second Lien Creditor in any proceeding by Senior Secured Creditor to
foreclose or otherwise enforce any of its security interests in and/or Liens on
any of the Collateral.

         Section 21. Financial Condition of Borrower and Guarantors. Second Lien
Creditor hereby assumes responsibility for keeping itself informed of the
condition (whether financial or otherwise) of Borrower, any and all Guarantors,
and the description of, title to or value of any of the Collateral and the
perfection and priority or any security interest or Lien securing any or all of
the Senior Secured Debt or the Second Lien Debt, and of all other circumstances
bearing upon the risk of non-payment of the Second Lien Debt that diligent
inquiry would reveal and Second Lien Creditor hereby agrees that Senior Secured
Creditor shall have no duty to advise Second Lien Creditor of any information
regarding such condition or any such circumstances.

         Section 22. Representations and Warranties. Each of the parties hereto
hereby represents and warrants that (a) it has full power, authority and legal
right to make and perform this Agreement, and (b) this Agreement is its legal,
valid and binding obligation, enforceable against it in accordance with its
terms.

         Section 23. Amendment. Neither this Agreement nor any of the terms
hereof may be amended, waived, discharged or terminated unless such amendment,
waiver, discharge or termination is in writing signed by Senior Secured Creditor
and Second Lien Creditor.

         Section 24. Successors and Assigns. This Agreement, and the terms,
covenants and conditions hereof, shall be binding upon, and inure to the benefit
of the successors and assigns of Senior Secured Creditor, Second Lien Creditor,
and Guarantors, regardless of whether Senior Secured Creditor, Second Lien
Creditor or Guarantors comply with the provisions of Section 12(b).

         Section 25. GOVERNING LAW. IN ALL RESPECTS, INCLUDING ALL MATTERS OF
CONSTRUCTION, VALIDITY, AND PERFORMANCE, THIS AGREEMENT AND THE OBLIGATIONS
ARISING HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF TEXAS APPLICABLE TO CONTRACTS MADE AND PERFORMED

<PAGE>

agreements, documents and instruments as may be necessary or as Senior Secured
Creditor may from time to time reasonably request to effect provisions of this
Agreement. The Second Lien Creditor hereby agrees to make reference in all
Second Lien Loan Documents to its obligations under this Agreement including,
without limitation, that all the liens and security interests created by the
Second Lien Loan Documents are subordinate to the liens and security interests
created by the Senior Lien Documents.

         Section 28. Modifications in Writing. No amendment, modification,
supplement, termination, consent or waiver of or to any provision of this
Agreement nor any consent to any departure therefrom shall in any event be
effective unless the same shall be in writing and signed by or on behalf of each
party hereto. Any waiver of any provision of this Agreement, and any consent to
any departure from the terms of any provision of this Agreement, shall be
effective only in the specific instance and for the specific purpose for which
given.

         Section 29. Severability. Whenever possible, each provision of this
Agreement shall be interpreted in such a manner as to be effective and valid
under applicable law, but if any provision of this Agreement shall be prohibited
by or invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of such provisions or the remaining provisions of this Agreement.

         Section 30. Equitable Remedies. Each party to this Agreement
acknowledges that the breach by it of any of the provisions of this Agreement is
likely to cause irreparable damage to the other party. Therefore, the relief to
which any party shall be entitled in the event of any such breach or threatened
breach shall include, but not be limited to, a mandatory injunction for specific
performance, injunctive or other judicial relief to prevent a violation of any
of the provisions of this Agreement, damages and any other relief to which it
may be entitled at law or in equity.

         Section 31. Revival. Second Lien Creditor further agrees that, to the
extent that any Loan Party makes a payment or payments to Senior Secured
Creditor, which payment or payments or any parts thereof are subsequently
invalidated, avoided, declared to be fraudulent or preferential, set aside, or
required to be repaid to a debtor in possession, a trustee, a receiver or any
other party under Title 11, United States Code, any state or federal law, common
law, or equitable cause, then to the extent of such payment or repayment, the
obligation or part thereof intended to be satisfied shall be revived and
continued in full force and effect as a part of the obligations of the Loan
Parties under the Senior Secured Debt as if such payment had not been made, and
shall be subject in all respects to the subordination and other provisions in
favor of Senior Secured Creditor hereunder.

         Section 32. Exculpation Provisions. Each of the parties hereto
specifically agrees that it has a duty to read this Agreement and the Security
Instruments and agrees that it is charged with notice and knowledge of the terms
of this Agreement and the Security Instruments; 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 independently made its
own analysis of the financial condition of the Borrower and the Guarantors and
their assets including, without limitation, their Collateral; that it has been
represented by independent legal counsel of its choice throughout the
negotiations preceding its execution of this Agreement and the Security

                                      -15-
<PAGE>

Instruments; and has received the advice of its attorney in entering into this
Agreement and the Security Instruments; and that it recognizes that certain of
the terms of this Agreement and the Security Instruments 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 Security Instruments on the
basis that the party had no notice or knowledge of such provision or that the
provision is not "conspicuous."

         Section 33. WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN
CONNECTION WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY
RESOLVED BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE
FEDERAL AND STATE LAWS TO APPLY, TO THE EXTENT THAT THE PROVISIONS OF SECTION 35
HEREOF ARE DETERMINED TO BE UNENFORCEABLE, THE PARTIES DESIRE THAT THEIR
DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO
ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF
ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
SUIT, OR PROCEEDING BROUGHT TO ENFORCE OR DEFEND ANY RIGHTS OR REMEDIES UNDER
THIS AGREEMENT.

         Section 34. NO ORAL AGREEMENTS. THIS AGREEMENT AND THE LOAN DOCUMENTS
EMBODY THE ENTIRE AGREEMENT AND UNDERSTANDING BETWEEN THE PARTIES AND SUPERSEDE
ALL OTHER AGREEMENTS AND UNDERSTANDINGS BETWEEN SUCH PARTIES RELATING TO THE
SUBJECT MATTER HEREOF AND THEREOF. THIS AGREEMENT AND THE LOAN DOCUMENTS
REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES 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.

         Section 35. Arbitration.

                  (a)      Arbitration. The parties hereto agree, upon demand by
any party, to submit to binding arbitration all claims, disputes and
controversies between or among them (and their respective employees, officers,
directors, attorneys, and other agents), whether in tort, contract or otherwise
arising out of or relating to in any way (i) this Agreement and related
documents which are the subject of this Agreement and its negotiation,
execution, collateralization, administration, repayment, modification,
extension, substitution, formation, inducement, enforcement, default or
termination; or (ii) requests for additional credit.

                  (b)      Governing Rules. Any arbitration proceeding will (i)
proceed in a location in Texas selected by the American Arbitration Association
("AAA"); (ii) be governed by the Federal Arbitration Act (Title 9 of the United
States Code), notwithstanding any conflicting choice of law provision in any of
the documents between the parties; and (iii) be conducted by the AAA, or such
other administrator as the parties shall mutually agree upon, in accordance with
the AAA's commercial dispute resolution procedures, unless the claim or
counterclaim is at least $1,000,000.00 exclusive of claimed interest,
arbitration fees and costs in which case the arbitration shall be conducted in
accordance with the AAA's optional procedures for large,

                                      -16-
<PAGE>

complex commercial disputes (the commercial dispute resolution procedures or the
optional procedures for large, complex commercial disputes to be referred to, as
applicable, as the "Rules"). If there is any inconsistency between the terms
hereof and the Rules, the terms and procedures set forth herein shall control.
Any party who fails or refuses to submit to arbitration following a demand by
any other party shall bear all costs and expenses incurred by such other party
in compelling arbitration of any dispute. Nothing contained herein shall be
deemed to be a waiver by any party that is a bank of the protections afforded to
it under 12 U.S.C. Section 91 or any similar applicable state law.

                  (c)      No Waiver of Provisional Remedies, Self-Help and
Foreclosure. The arbitration requirement does not limit the right of any party
(unless prohibited by the terms of this Agreement) to (i) foreclose against real
or personal property collateral; (ii) exercise self-help remedies relating to
collateral or proceeds of collateral such as setoff or repossession; or (iii)
obtain provisional or ancillary remedies such as replevin, injunctive relief,
attachment or the appointment of a receiver, before during or after the pendency
of any arbitration proceeding. This exclusion does not constitute a waiver of
the right or obligation of any party to submit any dispute to arbitration or
reference hereunder, including those arising from the exercise of the actions
detailed in Sections (i), (ii) and (iii) of this paragraph.

                  (d)      Arbitrator Qualifications and Powers. Any arbitration
proceeding in which the amount in controversy is $5,000,000.00 or less will be
decided by a single arbitrator selected according to the Rules, and who shall
not render an award of greater than $5,000,000.00. Any dispute in which the
amount in controversy exceeds $5,000,000.00 shall be decided by majority vote of
a panel of three arbitrators; provided, however, that all three arbitrators must
actively participate in all hearings and deliberations. The arbitrator will be a
neutral attorney licensed in the State of Texas with a minimum of ten years
experience in the substantive law applicable to the subject matter of the
dispute to be arbitrated. The arbitrator will determine whether or not an issue
is arbitratable and will give effect to the statutes of limitation in
determining any claim. In any arbitration proceeding the arbitrator will decide
(by documents only or with a hearing at the arbitrator's discretion) any
pre-hearing motions which are similar to motions to dismiss for failure to state
a claim or motions for summary adjudication. The arbitrator shall resolve all
disputes in accordance with the substantive law of Texas and may grant any
remedy or relief that a court of such state could order or grant within the
scope hereof and such ancillary relief as is necessary to make effective any
award. The arbitrator shall also have the power to award recovery of all costs
and fees, to impose sanctions and to take such other action as the arbitrator
deems necessary to the same extent a judge could pursuant to the Federal Rules
of Civil Procedure, the Texas Rules of Civil Procedure or other applicable law.
Judgment upon the award rendered by the arbitrator may be entered in any court
having jurisdiction. The institution and maintenance of an action for judicial
relief or pursuit of a provisional or ancillary remedy shall not constitute a
waiver of the right of any party, including the plaintiff, to submit the
controversy or claim to arbitration if any other party contests such action for
judicial relief.

                  (e)      Discovery. In any arbitration proceeding discovery
will be permitted in accordance with the Rules. All discovery shall be expressly
limited to matters directly relevant to the dispute being arbitrated and must be
completed no later than twenty (20) days before the

                                      -17-
<PAGE>

hearing date and within one hundred and eighty (180) days of the filing of the
dispute with the AAA. Any requests for an extension of the discovery periods, or
any discovery disputes, will be subject to final determination by the arbitrator
upon a showing that the request for discovery is essential for the party's
presentation and that no alternative means for obtaining information is
available.

                  (f)      Class Proceedings and Consolidations. The resolution
of any dispute arising pursuant to the terms of this Agreement shall be
determined by a separate arbitration proceeding and such dispute shall not be
consolidated with other disputes or included in any class proceeding.

                  (g)      Payment of Arbitration Costs and Fees. The arbitrator
shall award all costs and expenses of the arbitration proceeding.

                  (h)      Miscellaneous. To the maximum extent practicable, the
AAA, the arbitrators and the parties shall take all action required to conclude
any arbitration proceeding within one hundred and eighty (180) days of the
filing of the dispute with the AAA. No arbitrator or other party to an
arbitration proceeding may disclose the existence, content or results thereof,
except for disclosures of information by a party required in the ordinary course
of its business or by applicable law or regulation. If more than one agreement
for arbitration by or between the parties potentially applies to a dispute, the
arbitration provision most directly related to this Agreement or the subject
matter of the dispute shall control. This arbitration provision shall survive
termination, amendment or expiration of this Agreement, any document executed in
connection herewith, or any relationship between the parties.

         Section 36. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. Signatures given by
facsimile or other electronic transmission shall be binding and effective as
originals.

                              CONSULTING AGREEMENT

         This Consulting Agreement ("Agreement") is made effective and entered
into as of December 1, 2003, by and between SAVE THE WORLD AIR, INC., a Nevada
corporation (the "Company"), and JOSEPH HELLEIS ("Consultant"), with reference
to the following facts:

                                    RECITALS

          A.   The Company has developed proprietary technologies for reducing
               harmful emissions from fuel combustion engines and improving fuel
               efficiency, among other benefits and is currently in process of
               organizational development as it prepares to bring its products
               to market.

          B.   The Company desires to engage the services of Consultant as an
               independent contractor to assist with organizational and
               administrative matters, as specified by the Company from time to
               time during its transitional period of development.

          C.   Consultant has expertise in the area of the Company's business
               requirements and desires to provide consulting services for the
               Company upon the terms and conditions contained herein.

         NOW, THEREFORE, the Company and Consultant hereby mutually agree as
follows:

         Section 1. Scope of Services to be provided. Development of Company
         Policies and Procedures and such policies' implementation and
         administration when deemed appropriate by the Company.

               (a)  Consultant shall undertake and perform the tasks outlined.
                    in Section 1 and such additional or other responsibilities
                    as may be reasonably assigned to Consultant from time to
                    time by the Company's Chief Executive Officer, President and
                    Chief Operating Officer.

               (b)  Consultant shall keep confidential any proprietary or
                    confidential information of the Company, including without
                    limitation all information that may constitute a trade
                    secret or otherwise confer strategic or competitive
                    advantages to the Company, by use of passwords, locked
                    cabinets, identification of such information and materials
                    as "Confidential" and other limits on access as may be
                    customary or appropriate or set forth in Company policies.

         Section 2. Non-Disclosure Obligations. Concurrently with the parties'
                    execution of this Agreement, Consultant shall execute and
                    deliver to the Company the Confidentiality Agreement
                    attached hereto as Annex B (the "Confidentiality
                    Agreement"), the provisions of which are incorporated herein
                    by this reference.

<PAGE>

         Section 3. Consultant's Representations and Covenants. Consultant
                    represents, warrants and covenants to the Company that:

               (a)  Consultant shall devote such time, energy, interest,
                    ability, and skill as may be fairly and reasonably necessary
                    to provide to the Company the services described in Section
                    1 above.

               (b)  Consultant shall not, during the term of this Agreement,
                    directly or indirectly, promote, participate, or engage in
                    any business activity that would materially interfere with
                    the performance of Consultant's duties under this Agreement
                    or which is competitive with the Company's or any Company
                    Affiliate's business, including, without limitation, any
                    involvement as a shareholder, director, officer, employee,
                    partner, joint venturer, consultant, advisor, individual
                    proprietor, lender, or agent of any business, without the
                    prior written consent of the Company. The term "Affiliate"
                    shall mean, with respect to any person or entity, any other
                    person or entity which, directly or indirectly through one
                    or more intermediaries, is in control of, is controlled by
                    or is under common control with, such person or entity.
                    "Control of," "controlled by" and "under common control
                    with" mean the possession, directly or indirectly, of the
                    power to direct or cause the direction of the management
                    policies of a person or entity, by contract or credit
                    arrangement, as trustee or executor, or otherwise. The term
                    "Affiliate" includes, but is not limited to, each and every
                    subsidiary of the Company.

               (c)  During the term of this Agreement and for a period of one
                    year after the termination of this Agreement, Consultant
                    shall not solicit, attempt to solicit, or cause to be
                    solicited any customers of the Company for purposes of
                    promoting or selling products or services which are
                    competitive with those of the Company, nor shall Consultant
                    solicit, attempt to solicit, or cause to be solicited any
                    employees, agents, or other independent contractors of the
                    Company to cease their relationship with the Company.

               (d)  Consultant does not have any agreements with or commitments
                    to any other person or entity which conflict with any of
                    Consultant's obligations to the Company arising under this
                    Agreement.

               (e)  Consultant shall maintain any and all licenses and permits
                    as may be required for Consultant to provide the consulting
                    services contemplated hereby. In the event Consultant shall
                    utilize the services or shall acquire any products in order
                    to render the consulting services contemplated hereby,
                    Consultant shall be solely responsible for the payment for
                    such services and products, except to the extent
                    reimbursable by the Company in accordance with 0 below.
                    Consultant shall be solely responsible for any and all
                    income and other taxes that may be due to any state, local
                    or federal governmental authorities in respect of the

                    supersede all prior agreements, written or oral, on the
                    subject matter hereof. Neither party hereto shall have a

        Section 17. Severability of Provisions. Any provision in this
                    Agreement that is held to be inoperative, unenforceable, or
                    invalid in any jurisdiction shall be, as to that
                    jurisdiction only, inoperative, unenforceable, or invalid
                    without affecting the remaining provisions in that
                    jurisdiction or the operation, enforceability, or validity
                    of those provisions in any other jurisdiction, and to this
                    end the provisions of this Agreement shall be severable.

        Section 18. Headings. Headings of this Agreement are included for
                    convenience only and shall not be considered a part of this

        Section 19. Attorneys' Fees. In the event of any litigation or other
                    dispute arising as a result of or by reason of this
                    Agreement, the prevailing party in any such litigation or
                    other dispute shall be entitled to, in addition to any other
                    damages assessed, its reasonable attorneys' fees, and all
                    other costs and expenses incurred in connection with
                    settling or resolving such dispute. The attorneys' fees
                    which the prevailing party is entitled to recover shall
                    include fees for prosecuting or defending any appeal and
                    shall be awarded for any supplemental proceedings until the
                    final judgment is satisfied in full. In addition to the
                    foregoing award of attorneys' fees to the prevailing party,
                    the prevailing party in any lawsuit on this Agreement shall
                    be entitled to its reasonable attorneys' fees incurred in
                    any post judgment proceedings to collect or enforce the
                    judgment. This attorneys' fees provision is separate and
                    several and shall survive the merger of this Agreement into
                    any judgment.

        Section 20. Waiver; Rights and Remedies. Neither Consultant's nor the
                    Company's failure to exercise any right under this Agreement
                    shall constitute a waiver of any other term or condition of
                    this Agreement with respect to any other preceding,
                    concurrent, or subsequent breach, nor shall it constitute a
                    waiver by the Company or Consultant of its rights at any
                    time thereafter to require exact and strict compliance with
                    any of the terms of this Agreement. The rights and remedies
                    set forth in this Agreement shall be in addition to any
                    other rights or remedies which may be granted by law.

                           certain Consulting Agreement of even date herewith,
                           between the Company and Consultant ("Consulting
                           Agreement").

         B.                The Company has retained the services of Consultant
                           to provide Policies and Procedures and other services

         C.                The Company desires to protect various proprietary
                           and confidential information that it uses in its
                           business.

         Therefore, the parties hereto do hereby agree as follows:

         1.       Definition of Confidential Information.

                  (a)      For the purposes of this Agreement, the term
"Confidential Information" shall mean information, material and trade secrets
(i) proprietary to the Company or to any Affiliate (as defined below) of the
Company or (ii) designated as confidential by the Company, whether or not owned
or developed by the Company, which Consultant may obtain knowledge of or access
to, through or as a result of, Consultant's relationship with the Company or
with any Affiliate of the Company.

                  (b)      Without limiting the generality of the foregoing,
Confidential Information shall include, but is not limited to, the following
types of information and other information of a similar nature (whether or not
reduced to writing or still in development):

                  (iv)     Any information described above which Company obtains

the power to direct or cause the direction of the management policies of a

DEEMED PART OF THE CONFIDENTIAL INFORMATION.

                  (f)      Any capitalized terms used and not otherwise defined

Agreement.

         2.       Confidential Treatment. Consultant hereby agrees, during the
term of his consulting arrangement with Company and at all times thereafter, to
hold in confidence and not to directly or indirectly reveal, report, publish,
disclose or transfer any of the Confidential Information to any person or
entity, or utilize any of the Confidential Information for any purpose, except
in the course of Consultant's services for Company, without the prior written
consent of the chief executive officer of Company. Consultant agrees that, as
between Consultant and Company, Company owns all of the Confidential
Information, and Consultant hereby agrees to regard and preserve as confidential
all Confidential Information. Consultant hereby agrees not to take, retain or
copy, without the prior written consent of the chief executive officer of
Company, any or all of the Confidential Information. Without limiting the
generality of the foregoing, during the term hereof and after termination of
Consultant's employment with the Company, Consultant shall not use, build,
reverse-engineer, decompile, modify for use or disassemble any of the
Technology.

         3.       Ownership. The Technology including without limitations any
and all Creations shall be the sole and exclusive property of the Company. At
any time upon the request of the Company, Consultant shall: (i) assign, without
charge to the Company, all his rights, title, and interests in any of the
Creations to the Company; (ii) execute, acknowledge, and deliver any and all
instruments necessary to confirm the Company's complete ownership of the
Creations; and (iii) perform all other reasonable acts which may be necessary to
perfect and to protect the Company's ownership rights in the Creations.
Consultant hereby assigns to the Company all of his right, title and inters in
and to the Creations. Consultant shall disclose promptly and only to

                                       -2-
<PAGE>

the Company, and shall make an adequate record of, any and all Creations
conceived or developed by Consultant (either alone or jointly with others)
during the term of this Agreement and within one year thereafter, whether or not
the property of the Company.

         4.       Return of Materials and Copies. All notes, data, reference
materials, sketches, drawings, memoranda, documentation and records in any way
incorporating or reflecting any of the Confidential Information and all
proprietary rights therein, including copyrights, shall belong exclusively to
Company, and Consultant hereby agrees to turn over promptly all copies of such
materials in Consultant's control to Company upon Company's request or upon
termination of Consultant's employment by Company.

         5.       Non-Competition and Non-Solicitation. During the Company's
employment of Consultant and for a period of two (2) years following the term of
the Consulting Agreement, Consultant shall not assist, become employed by or
engage in any consulting or other services for any person or entity that is
engaged in any business or other activity in competition with the Company, nor
solicit or entice any of the Company's employees to do any of the foregoing.
During the Company's employment of Consultant and for a period of two (2) years
following the term of the Consulting Agreement, Consultant shall not set up or
take preliminary steps to set up or engage in any business enterprise that would
be in competition with the Company and Consultant shall disclose to the Company,
any and all competitive plans that Consultant may have, without regard to
Consultant's intent to act or not act on such plans.

         6.       Fiduciary Obligations. Nothing in this Agreement is intended
to limit Consultant's obligations to Company in any capacity, and Consultant
shall be bound by all fiduciary and other obligations to Company which may arise
by reason of Consultant's employment, capacity or other duties to the Company.

         7.       Injunctive Relief. Due to the unique nature of the
Confidential Information, Consultant understands and hereby agrees that Company
will suffer irreparable harm in the event that Consultant fails to comply with
any of Consultant's obligations under Section 2 or 3 above and that monetary
damages will be inadequate to compensate Company for such breach. Accordingly,
Consultant hereby agrees that Company will be entitled, in addition to any other
remedies available to it at law or in equity, to injunctive relief to enforce
the terms of Sections 2 and 3 above.

         8.       Amendments; Consents. No amendment, modification, supplement,
termination or waiver of any provision in this Agreement, and no consent to any
departure therefrom, shall be effective unless in writing and signed by both
Consultant and Company and then only in the specific instance and for the
specific purpose given.

         9.       Notice. Any notices required or permitted to be given in
writing and will be deemed received when personally delivered or, if earlier,
ten (10) days after mailing by registered or certified United States mail,
postage prepaid, and with return receipt requested. Notice to the Company is
valid if sent to the Company's principal place of business and notice to
Consultant is valid if sent to Consultant at Consultant's address as it appears
in the Company's records.

         10.      Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, and all such
counterparts when taken together shall be deemed to be but one and the same
instrument.

obligations hereunder, shall not be assigned or transferred by Consultant
without the prior written consent of Company.

Consulting Agreement) shall comprise the complete and integrated agreement of
the Company and Consultant and shall supersede all prior agreements, written or
oral, on the subject matter hereof. Neither party hereto shall have a provision
construed against it by reason of such party having drafted the same.

         13.      Governing Law. This Agreement shall be governed by, and
construed and enforced in accordance with, the laws of the State of California.

         14.      Severability of Provisions. Any provision in this Agreement
that is held to be inoperative, unenforceable or invalid in any jurisdiction
shall be, as to that jurisdiction only, inoperative, unenforceable or invalid
without affecting the remaining provisions in that jurisdiction or the
operation, enforceability or validity of those provisions in any other
jurisdiction, and to this end the provisions of this Agreement shall be
