                  created by this Agreement and the Permitted Liens in the
                  Collateral, each of the Companies shall at its own expense

                                       11


                  defend the Collateral against any and all liens, claims,
                  security interests and other encumbrances or interests,
                  howsoever arising and shall maintain and preserve the security
                  interest granted hereunder with respect to the Collateral as
                  long as this Agreement shall remain in full force and effect.
                  None of the Companies shall make any other pledge, assignment,
                  mortgage, hypothecation or transfer of the Collateral except
                  as permitted hereunder or under the Restructured O&G
                  Agreement.

                           (f) Each of the Companies shall at all times keep
                  accurate and complete records with respect to the Collateral,
                  including, without limitation, records of all payments made,
                  credit granted and proceeds received in connection therewith.

                           (g) None of the Companies shall relocate its
                  principal place of business or chief executive office to a
                  county or state other than that specified in Section 3(a) of
                  this Agreement unless such Company gives 30 days' prior
                  written notice to the Secured Party, which notice shall
                  specify the county and state into which such relocation is to
                  be made. The Collateral, to the extent not delivered to the
                  Secured Party pursuant to Section 2, will be kept at those
                  locations listed on the Perfection Certificate delivered to
                  the Secured Party herewith in the form attached as Exhibit A
                  hereto and none of the Companies will remove the Collateral
                  from such locations, without providing at least 30 days' prior
                  written notice to the Secured Party.

                           (h) Each of the Companies will keep the Collateral in
                  good order and repair, except in situations where not to do so
                  would not be material, and will not use the same in violation
                  of law or any policy of insurance thereon. The Secured Party,
                  or its designee, may inspect the Collateral at any reasonable
                  time, wherever located.

                           (i) The Secured Party, or its representative, shall
                  at all times have full and free access during normal business
                  hours to all of the books, correspondence and records of each
                  of the Companies relating to the Collateral (other than
                  information that is privileged and confidential) and the
                  Secured Party and its representatives may examine the same,
                  make abstracts therefrom and make photocopies thereof, and the
                  Companies agrees to render to the Secured Party, at the
                  Companies' cost and expense, such clerical and other
                  assistance as may be reasonably requested by the Secured Party
                  with regard thereto.

                           (j) The Companies shall not permit any of the Pledged
                  Subsidiaries to issue to the Companies any securities of the
                  type required to be pledged hereunder unless such securities
                  are promptly pledged and delivered hereunder to the Secured
                  Party or its designated agent in accordance with Section 2(b).

                           (k) If, while this Agreement is in effect, any stock
                  dividend, stock split, reclassification, readjustment,
                  reorganization, merger, consolidation, exchange offer, tender
                  offer or other change in the capital structure, including the
                  creation of any subscription or other rights relating to the
                  Pledged Securities, is declared or made, or proposed to be
                  declared or made, by any of the Pledged Subsidiaries or any
                  other issuer of the Collateral, all substituted and additional
                  securities or interest issued with respect to the Collateral
                  and evidenced by certificates shall be endorsed in blank by
                  the applicable Companies promptly upon receipt thereof or
                  otherwise appropriately transferred to the

                                       12


                  Secured Party in negotiable form, and all certificates or
                  instruments evidencing such securities shall be delivered to
                  the Secured Party to be held under the terms of this Agreement
                  in the same manner as, and as a part of, the Collateral. All
                  Pledged Securities shall be evidenced by one or more
                  certificates. Any securities that may be issued upon exercise
                  of any subscription or other rights relating to the Pledged
                  Securities shall be endorsed in blank and delivered to the
                  Secured Party with any necessary powers.

                  Section 5. Powers of the Secured Party.

                           (a) Each of the Companies hereby irrevocably
                  designates and appoints the Secured Party as its
                  attorney-in-fact, with full power of substitution, for the
                  purposes of carrying out the provisions of this Agreement and
                  taking any action and executing any instrument, including,
                  without limitation, any financing statement or continuation
                  statement, and taking any other action to maintain the
                  validity, perfection, priority and enforcement of the security
                  interest intended to be created hereunder, that the Secured
                  Party may reasonably deem necessary or advisable to accomplish
                  the purposes hereof, which appointment as attorney-in-fact is
                  irrevocable and coupled with an interest.

                           (b) Without limiting the generality of Section 5(a)
                  hereof, each of the Companies hereby irrevocably authorizes
                  and empowers the Secured Party, upon the occurrence and during
                  the continuation of any Event of Default, at the expense of
                  such Companies, either in the Secured Party's own name or in
                  the name of any Companies, at any time and from time to time:

                                    (i) to ask, demand, receive, issue a receipt
                           for, give acquittance for, settle and compromise any
                           and all monies which may be or become due or payable
                           or remain unpaid at any time or times to any of the
                           Companies, and any and all other property which may
                           be or become deliverable at any time or times to any
                           of the Companies, under or with respect to the
                           Collateral;

                                    (ii) to endorse any drafts, checks, orders
                           or other instruments for the payment of money payable
                           to any of the Companies on account of the Collateral
                           (including any such draft, check, order or instrument
                           issued by any insurance company payable jointly to
                           any of the Companies and the Secured Party); and

                                    (iii) to settle, compromise, prosecute or
                           defend any action, claim or proceeding, or take any
                           other action, all either in its own name or in the
                           name of any of the Companies or otherwise, which the
                           Secured Party may deem to be necessary or advisable
                           for the purpose of exercising and enforcing its
                           powers and rights under this Agreement or in
                           furtherance of the purposes hereof, including any
                           action which by the terms of this Agreement is to be
                           taken by any of the Companies.

                           (c) Nothing in this Agreement shall be construed as
                  requiring or obligating the Secured Party to make any
                  commitment or to make any inquiry as to the nature or
                  sufficiency of any payment received by it, or to present or
                  file any claim or notice, or to take any other action with
                  respect to any of the Collateral or any part thereof or the
                  amounts due or to become due in respect thereof or any
                  property covered thereby, or to

                                       13


                  collect or enforce the payment of any amounts assigned to it
                  or to which it may otherwise be entitled hereunder at any time
                  or times other than to account for amounts or Collateral
                  received.

                           (d) The Secured Party shall be entitled at any time
                  to file this Agreement, or a carbon, photographic or any other
                  reproduction of this Agreement, as a financing statement, but
                  the failure of the Secured Party to do so shall not impair the
                  validity or enforceability of this Agreement. The Secured
                  Party shall have no duty to comply with any recording, filing
                  or other legal requirements necessary to establish or maintain
                  the validity, priority or enforceability of, or the Secured
                  Party's rights in or to, any of the Collateral.

                           (e) In its discretion, the Secured Party may
                  discharge taxes and other encumbrances at any time levied or
                  placed on any of the Collateral, make repairs thereto and pay
                  any necessary filing fees. Each of the Companies agrees to
                  reimburse the Secured Party on demand for any and all
                  reasonable expenditures so made with interest on unpaid
                  amounts at the maximum rate permitted by law. The Secured
                  Party shall have no obligation to any of the Companies to make
                  any such expenditures, nor shall the making thereof relieve
                  any of the Companies of any default.

                           (f) Anything herein to the contrary notwithstanding,
                  each of the Companies shall remain liable under each contract
                  or agreement comprised in the Collateral to be observed or
                  performed by such Companies thereunder. The Secured Party
                  shall not have any obligation or liability under any such
                  contract or agreement by reason of or arising out of this
                  Agreement or the receipt by the Secured Party of any payment
                  relating to any of the Collateral, nor shall the Secured Party
                  be obligated in any manner to perform any of the obligations
                  of any of the Companies under or pursuant to any such contract
                  or agreement, to make inquiry as to the nature or sufficiency
                  of any payment received by the Secured Party in respect of the
                  Collateral or as to the sufficiency of any performance by any
                  party under any such contract or agreement, to present or file
                  any claim, to take any action to enforce any performance or to
                  collect the payment of any amounts which may have been
                  assigned to the Secured Party or to which the Secured Party
                  may be entitled at any time or times other than to account for
                  amounts or Collateral received, and no action taken or omitted
                  shall give rise to any defense, counterclaim or right of
                  action against the Secured Party, unless the Secured Party's
                  actions are taken or omitted to be taken with gross negligence
                  or bad faith or constitute willful misconduct. The Secured
                  Party's sole duty with respect to the custody, safe keeping
                  and physical preservation of the Collateral in its possession,
                  under Section 9-207 of the UCC or otherwise, shall be to deal
                  with such Collateral in the same manner as the Secured Party
                  deals with similar property for its own account.

                           (g) If an Event of Default has occurred and is
                  continuing, the Secured Party may at any time, at its option,
                  transfer to itself or any nominee any securities constituting
                  the Pledged Securities, receive any income thereon and hold
                  such income as additional Collateral or apply it to the
                  Obligations. Regardless of whether any Obligations are due,
                  the Secured Party may demand, sue for, collect, or make any
                  settlement or compromise, which it deems desirable with
                  respect to the Collateral. Regardless of the adequacy of

                                       14


                  Collateral or any other security for the Obligations, any
                  deposits or other sums at any time credited by or due from the
                  Secured Party to any of the Companies may at any time be
                  applied to or setoff against any of the Obligations.

                           (h) If an Event of Default has occurred and is
                  continuing, the Secured Party shall have all of the rights
                  with respect to the UCC Collateral as may be available to
                  secured parties under the UCC.

                           (i) If an Event of Default shall have occurred and be
                  continuing, each of the Companies shall, at the request of the
                  Secured Party, notify obligors on chattel paper and general
                  intangibles of the Companies and obligors on instruments for
                  which any of the Companies is an obligee of the security
                  interest of the Secured Party in any chattel paper, general
                  intangible or instrument and that payment thereof is to be
                  made directly to the Secured Party or to any financial
                  institution designated by the Secured Party as the Secured
                  Party's agent therefor, and the Secured Party may itself, if
                  an Event of Default shall have occurred and be continuing,
                  without notice to or demand upon the Companies, so notify said
                  obligors. After the making of such a request or the giving of
                  any such notification, each of the Companies shall hold any
                  proceeds of collection of chattel paper, general intangibles
                  and instruments received by such Companies as trustee for the
                  Secured Party without commingling the same with other funds of
                  such Companies and shall turn the same over to the Secured
                  Party in the identical form received, together with any
                  necessary endorsements or assignments. The Secured Party shall
                  apply the proceeds of collection of chattel paper, general
                  intangibles and instruments received by the Secured Party to
                  the Obligations, such proceeds to be immediately entered after
                  final payment in cash of the items giving rise to them.

                  Section 6. Voting Rights, Dividends, Etc.

                           (a) Until an Event of Default shall have occurred and
                  be continuing:

                                    (i) except as otherwise provided in this
                           Agreement, each of the Companies shall be entitled to
                           exercise any and all voting or consensual rights and
                           powers, including subscription rights, in relation to
                           the Pledged Securities; provided, however, that no
                           vote shall be cast or consent, waiver or ratification
                           given or action taken which would materially impair
                           the securities or the value thereof or violate any
                           provision of this Agreement, the Restructured O&G
                           Agreement or any other ancillary document;

                                    (ii) except as otherwise provided in this
                           Agreement, each of the Companies shall be entitled to
                           receive and retain any and all dividends,
                           distributions or other payments in respect of the
                           Pledged Securities and the Secured Party, upon
                           receipt of any of the foregoing, shall promptly pay
                           or distribute the same to the applicable Companies,
                           and, to the extent so permitted, any distributions
                           received by such Companies and transferred to other
                           persons shall pass free and clear of the lien and
                           security interest hereof; and

                                    (iii) the Secured Party shall execute and
                           deliver to each of the Companies or cause to be
                           executed and delivered to such Companies, all such

                                       15


                           proxies, powers of attorney, dividend orders and
                           other instruments as such Companies may reasonably
                           request for the purpose of enabling it to exercise
                           the voting or consensual rights and powers which such
                           Companies is entitled to exercise pursuant to the
                           foregoing Section 6(a)(i) or to receive the
                           dividends, distributions or other payments which such
                           Companies is authorized to retain pursuant to the
                           foregoing Section 6(a)(ii).

                           (b) Upon the occurrence and during the continuance of
                  an Event of Default, all rights of each of the Companies to
                  exercise the voting or consensual rights and powers which it
                  would otherwise be entitled to exercise pursuant to Section
                  6(a)(i) and to receive the dividends, distributions and other
                  payments which the Pledgor would otherwise be authorized to
                  receive and retain pursuant to Section 6(a)(ii) shall
                  automatically cease, and all such rights shall thereupon
                  become vested in the Secured Party, which shall then have the
                  sole and exclusive right and authority to exercise, in its
                  sole discretion, all such voting and consensual rights and
                  powers and to receive and retain as Collateral all such
                  dividends, distributions and other payments. Without limiting
                  the foregoing, in such event the Secured Party may exercise
                  all voting and corporate rights at any meeting of any
                  corporation issuing any such securities and any and all rights
                  of conversion, exchange, subscription or any other rights,
                  privileges or options pertaining to any such securities as if
                  it were the absolute owner thereof, including, without
                  limitation, the rights to exchange at its discretion, any and
                  all such securities upon the merger, consolidation,
                  reorganization, recapitalization or other readjustment of any
                  corporation issuing any such securities or upon the exercise
                  by any such issuer or the Secured Party of any right,
                  privilege or option pertaining to any such securities, and, in
                  connection therewith, to deposit and deliver any and all
                  securities with any committee, depository, transfer agent,
                  registrar or other designated agency upon such terms and
                  conditions as it may determine, all without liability except
                  to account for the property actually received by it, but the
                  Secured Party shall have no duty to exercise any of the
                  aforesaid rights, privileges or options and the Secured Party
                  shall not be responsible for any failure to do so or delay in
                  so doing.

                  Section 7. Default.

                           (a) It shall constitute a Default or an Event of
                  Default under this Agreement if a "Default" or an "Event of
                  Default" shall occur under the Restructured O&G Agreement.

                           (b) If an Event of Default shall have occurred and is
                  continuing and if the Obligations are accelerated under the
                  provisions of the Restructured O&G Agreement, in addition to
                  any other rights and remedies that may be available to the
                  Secured Party under the UCC or the Restructured O&G Agreement
                  or under Section 5 of this Agreement or otherwise under this
                  Agreement or at law, the Secured Party shall also have the
                  following rights and powers:

                                    (i) The Secured Party may, without being
                           required to give any notice except as hereinafter
                           provided, sell the Collateral, or any part thereof,
                           at public or private sale, for cash, upon credit or
                           for future delivery and at such price or prices

                                       16


                           as the Secured Party deems satisfactory, and the
                           Secured Party and/or its collateral agent may be the
                           purchaser of any or all of the Collateral so sold and
                           thereafter hold the same absolutely free from any
                           right or claim of whatsoever kind, and the
                           Obligations or any portion of the Obligations may be
                           applied as a credit against the purchase price.

                                    (ii) Upon any such sale, the Secured Party
                           shall have the right to deliver, assign and transfer
                           to the purchaser thereof the Collateral so sold. Each
                           purchaser at any such sale shall hold the property
                           sold absolutely free from any claim or right of
                           whatsoever kind by or on behalf of any of the
                           Companies, including any equity or rights of
                           redemption of any of the Companies, and each of the
                           Companies hereby specifically waives, to the full
                           extent permitted by applicable law, all rights of
                           redemption, stay or appraisal which it has or may
                           have under any rule or law or statute now existing or
                           hereafter adopted.

                                    (iii) The Secured Party shall give each of
                           the Companies ten (10) business days' written notice
                           (which each of the Companies agrees is reasonable
                           notification within the meaning of Section 9-611 of
                           the UCC) of its intention to make any such public or
                           private sale. Such notice, in case of public sale,
                           shall state the time and place fixed for such sale
                           and, in case of a private sale, shall state the date
                           after which such sale is to be made.

                                    (iv) Any such public sale shall be held at
                           such time or times within ordinary business hours and
                           at such places as the Secured Party may fix in the
                           notices of such sale. At any such sale the Collateral
                           may be sold in one lot as an entirety or in separate
                           parcels, as the Secured Party may, in its sole
                           discretion, determine.

                                    (v) The Secured Party shall not be obligated
                           to make any sale of the Collateral of any part
                           thereof if it shall determine not to do so,
                           regardless of the fact that notice of sale of the
                           Collateral may have been given. The Secured Party
                           may, without notice or publication, adjourn any
                           public or private sale or cause the same to be
                           adjourned from time to time by announcement at the
                           time and place fixed for the sale, and such sale may,
                           without further notice, be made at any time or place
                           to which the same shall be so adjourned.

                                    (vi) In case of any sale of all or any part
                           of the Collateral on credit or for future delivery,
                           the Collateral so sold may be retained by the Secured
                           Party until the selling price is paid by the
                           purchaser thereof, but the Secured Party shall not
                           incur any liability in case of the failure of such
                           purchaser to take up and pay for the Collateral so
                           sold and, in case of any such failure, such
                           Collateral may again be sold upon like notice.

                                    (vii) The Secured Party, instead of
                           exercising the power of sale herein conferred upon
                           it, may proceed by a suit or suits at law or in
                           equity to exercise its remedies regarding the
                           Collateral and sell the Collateral, or any portion
                           thereof, under a judgment or decree of a court or
                           courts of competent jurisdiction.

                                       17


                                    (viii) Each of the Companies agrees that if
                           any Event of Default shall have occurred and be
                           continuing, then the Secured Party shall have the
                           right to take possession of the Collateral, and for
                           that purpose the Secured Party may, so far as any of
                           the Companies can give authority therefor, enter upon
                           any premises on which the Collateral may be situated
                           and remove the same therefrom with or without notice
                           or process of law. Each of the Companies waives any
                           and all rights that it may have to a judicial hearing
                           in advance of the enforcement of any of the Secured
                           Party's rights hereunder, including, without
                           limitation, its right following an Event of Default
                           to take immediate possession of the Collateral and to
                           exercise its rights with respect thereto.

                                    (ix) If under mandatory requirements of
                           applicable law, the Secured Party shall be required
                           to make disposition of the Collateral within a period
                           of time that does not permit the giving of notice to
                           the Companies as hereinbefore provided, the Secured
                           Party need give each of the Companies only such
                           notice of disposition as shall be reasonably
                           practicable in view of such mandatory requirements of
                           law.

                                    (x) The Secured Party may instruct the
                           obligor or obligors on any agreement, instrument or
                           other obligation constituting the Collateral to make
                           any payment or render any performance required by the
                           terms of such agreement, instrument or obligation
                           directly to the Secured Party or its designee.

                           (c) The Secured Party shall incur no liability as a
                  result of the sale of the Collateral, or any part thereof, at
                  any private sale other than for its own gross negligence,
                  willful misconduct or bad faith. Each of the Companies hereby
                  waives, to the maximum extent permitted by applicable law, any
                  claims against the Secured Party arising by reason of the fact
                  that the price at which the Collateral may have been sold at
                  such private sale was less than the price which might have
                  been obtained at a public sale or was less than the aggregate
                  amount of the Obligations, even if the Secured Party accepts
                  the first offer received and does not offer such Collateral to
                  more than one offeree.

                           (d) The Secured Party shall not be obligated to
                  pursue or exhaust its rights and remedies against any
                  particular Collateral or other security for the Obligations
                  before pursuing or enforcing its rights and remedies against
                  any other Collateral or other security for the Obligations.

                           (e) To the extent permitted by law, each of the
                  Companies hereby waives (i) any rights to require the Secured
                  Party to proceed first against any other Person, to exhaust
                  its rights in the Collateral or other security for the
                  Obligations or to pursue any other right that the Secured
                  Party might have, (ii) with respect to the Note, presentment
                  and demand for payment, protest, notice of protest and
                  nonpayment, notice of dishonor, notice of the intention to
                  accelerate and notice of acceleration (except as otherwise set
                  forth in the Restructured O&G Agreement), and (iii) all rights
                  of marshaling in respect of any and all of the Collateral.

                           (f) Without precluding any other methods of sale,
                  each of the Companies acknowledges that the sale of the
                  Collateral shall have been made in a commercially

                                       18


                  reasonable manner if conducted in conformity with reasonable
                  commercial practices of institutional lenders disposing of
                  similar property. The Secured Party shall not be liable for
                  any depreciation in the value of the Collateral.

                           (g) Each of the Companies agrees that its obligation
                  to deliver the Collateral is of the essence of this Agreement
                  and that accordingly, upon application to a court of equity
                  having jurisdiction, the Secured Party shall be entitled to a
                  decree requiring specific performance by the Companies of such
                  obligation.

                           (h) Remedies of the Secured Party are cumulative and
                  the exercise of any one or more of the remedies provided
                  herein shall not be construed as a waiver of any of the other
                  remedies of the Secured Party.

                           (i) If an Event of Default shall have occurred and be
                  continuing, the proceeds of any sale of or other realization
                  upon all or any part of the Collateral and any other amounts
                  held by the Secured Party under this Agreement shall be
                  applied by the Secured Party as provided in the Restructured
                  O&G Agreement.

                           Any amounts remaining after such applications and the
                  payment in full of the Note with respect to the Obligations
                  shall be remitted to the Companies, its successors or assigns,
                  or as a court of competent jurisdiction may otherwise direct.

                  Section 8. General Provisions.

                           (a) Continuing Security Interest; Binding Effect.
                  This Agreement shall create a continuing security interest in
                  the Collateral and shall (i) remain in full force and effect
                  until termination of the obligations of the Companies under
                  the Restructured O&G Agreement and the indefeasible payment in
                  full thereafter of the Obligations; (ii) be binding upon each
                  of the Companies and its successors and assigns; and (iii)
                  inure to the benefit of the Secured Party and its successors,
                  transferees and assigns. Without limiting the generality of
                  the foregoing clause (iii), the Secured Party may assign or
                  otherwise transfer any of its rights under this Agreement to
                  any other Person, and such Person shall thereupon become
                  vested with all the benefits in respect thereof granted herein
                  or otherwise to the Secured Party. Upon the termination of the
                  obligations of the Secured Party under the Restructured O&G
                  Agreement and the indefeasible payment in full thereafter of
                  the Obligations, each of the Companies shall be entitled to
                  the return, upon its request and at its expense, of such of
                  the Collateral as is in the Secured Party's possession and as
                  shall not have been sold or otherwise disposed of pursuant to
                  the terms hereof.

                           (b) Security Interest Absolute. The lien and security
                  interest created hereunder and the Companies' obligations
                  hereunder and the Secured Party's rights hereunder shall not
                  be released, diminished, impaired or adversely affected by the
                  occurrence of any one or more of the following events:

                                    (vii) any other circumstance (other than
                           payment in full of the Obligations) that might
                           otherwise constitute a defense available to, or a
                           discharge of, the Companies or any party to any
                           document in respect of the Obligations.

                           (c) Amendments. This Agreement or any term hereof may
                  be amended or changed only by an instrument in writing
                  executed jointly by each of the Companies and the Secured
                  Party and in accordance with the Restructured O&G Agreement.

                           (d) Remedies Cumulative. Each right, power and remedy
                  herein specifically granted to the Secured Party or otherwise
                  available to it or now or hereafter existing in law or in
                  equity shall be cumulative and concurrent, and shall be in
                  addition to every other right, power and remedy herein
                  specifically given or now or hereafter existing at law, in
                  equity, or otherwise (including, without limitation, all
                  rights, powers and remedies granted to a secured party under
                  the UCC), and each such right, power and remedy, whether
                  specifically granted herein or otherwise existing, may be
                  exercised at any time and from time to time as often and in
                  such order as may be deemed expedient by the Secured Party in
                  its sole and complete discretion. The provisions of this
                  Agreement may only be waived by an instrument in writing
                  signed by the Secured Party, and no failure on the part of the
                  Secured Party to exercise, and no delay in exercising, and no
                  course of dealing with respect to, any such right, power or
                  remedy, shall operate as a waiver thereof, nor shall any
                  single or partial exercise of any such right, power or remedy
                  preclude any other or further exercise thereof or the exercise
                  of any other right. No notice to or demand on any of the
                  Companies hereunder shall, of itself, entitle any of the
                  Companies to any other or further notice or demand in the same
                  or similar circumstances.

                           (e) Assignment. Neither this Agreement nor any
                  interest herein or in the Collateral, or any part thereof, may
                  be assigned by any of the Companies without the

                                       20


                  prior written consent of the Secured Party, except as
                  expressly permitted herein or in the Restructured O&G
                  Agreement.

                           (f) Headings. The descriptive headings of the several
                  sections of this Agreement are inserted for convenience only
                  and shall not control or affect the meaning or construction of
                  any of the provisions hereof.

                           (g) Severability. Any provision of this Agreement
                  that is prohibited or unenforceable in any jurisdiction shall,
                  as to such jurisdiction, be ineffective to the extent of such
                  prohibition or unenforceability without invalidating the
                  remaining provisions hereof or affecting the validity of
                  enforceability or such provision in any other jurisdiction.

                           (h) Survival. All representations and warranties
                  contained herein, in the Restructured O&G Agreement or made in
                  writing by any of the Companies in connection herewith or
                  therewith, shall survive the execution and delivery of this
                  Agreement, the Restructured O&G Agreement and any documents
                  executed in connection herewith or therewith.

                           (i) Counterparts; Facsimiles. This Agreement may be
                  executed in any number of counterparts and by different
                  parties in separate counterparts, each of which when so
                  executed and delivered shall be deemed to be an original, but
                  all of which when taken together shall constitute one and the
                  same instrument. A complete set of counterparts shall be
                  lodged with the Secured Party. Any signature delivered by fax
                  shall be deemed an original signature hereto.

                           (j) Waiver. To the extent permitted by applicable law
                  each of the Companies hereby waives promptness, diligence,
                  notice of acceptance and any other notice with respect to any
                  of the Restructured O&G Agreement obligations and this
                  Agreement and any requirement that the Secured Party protect,
                  secure, perfect or insure any security interest or any
                  property subject thereto or exhaust any right or take any
                  action against any of the Companies or any other person or
                  entity; provided however, that the Secured Party shall in any
                  event take such care in the handling of any Collateral in its
                  possession as it takes with respect to its own property of a
                  similar nature in its possession.

                           (k) Notices. Any notices or other communications
                  required or permitted hereunder shall be made in the manner
                  provided in the Restructured O&G Agreement.

                           (l) Conflicting Terms. In the event of any conflict
                  or inconsistency between the terms, covenants, conditions and
                  provisions set forth in this Agreement and the terms,
                  covenants, conditions and provisions set forth in the
                  Restructured O&G Agreement, the terms, covenants, conditions
                  and provisions of the Restructured O&G Agreement shall
                  prevail.

                  BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
