Each of Magma, CEOC and San Felipe is duly qualified to do business and is in good standing in the State of California and each other jurisdiction in which the character of the properties owned or leased by it or in which the transaction of its business as presently conducted or proposed to be conducted makes such qualification necessary or desirable. Pledgor has full corporate power and authority to own its property and to carry on its business as now being conducted and as proposed to be conducted. .2. Authority, Enforceability. Pledgor has full corporate power and authority to enter into and perform the Partnership Agreement and this Pledge Agreement and the entering into and performance of each such agreement by Pledgor has been duly authorized by all proper and necessary corporate action. Each such agreement, when executed and delivered by Pledgor and any other party thereto, will constitute the legal, valid and binding obligations of Pledgor, enforceable in accordance with its respective terms. .3. Title: No Other Liens. Pledgor is the legal and beneficial owner of the Collateral in existence on the date hereof and will be the sole owner of the Collateral hereafter acquired, free and clear of any and all Liens or claims of others except for Permitted Liens, and Pledgor has full corporate power and authority to grant the liens and security interests in and to the Collateral hereunder.

Perfection; Registration of Lien. Financing statements or other appropriate instruments have been filed or deposited for filing pursuant to the Code in such public 4 offices as may be necessary to perfect any Security Interest granted or purported to be granted hereby to the extent any such Security Interest may be perfected by the filing of a financing statement.

Subject to the requirements contained in the Code with respect to the filing of continuation statements, this Pledge Agreement constitutes a valid and continuing Lien on and perfected Security Interest (subject only to Permitted Liens) in the Collateral in favor of Collateral Agent for the equal and ratable benefit of the Secured Parties and the Funding Corporation, superior and prior to the rights of all Persons (subject only to Permitted Liens), whether the Collateral subject to the Security Interest is now owned by Pledgor or is hereafter acquired. .5.

This indemnity and any other obligations of Pledgor under any of the Financing Documents shall be made only against, and shall be limited to the extent of, the Collateral pledged hereunder. 5 . Pledgor's Obligations Upon Event of Default. If an Event of Default under the Partnership Credit Agreement or the Partnership Guarantee shall occur and be continuing (a) all payments received by Pledgor under or in connection with any of the Collateral shall be held by Pledgor in trust for Collateral Agent, shall be segregated from other funds of Pledgor and shall, forthwith upon receipt by Pledgor, be turned over to Collateral Agent or its designee in the same form as received by Pledgor (duly endorsed by Pledgor to Collateral Agent, if requested), and (b) any and all such payments so received by Collateral Agent or its designee (whether from Pledgor or otherwise) may, in the sole discretion of Collateral Agent or its designee, be held by Collateral Agent or such designee as collateral security for, and/or then or at any time thereafter be applied, subject only to the relevant provisions of the Intercreditor Agreement and the Depositary Agreement or as otherwise may be required by applicable law, in whole or in part by Collateral Agent or its designee in the manner specified in Section 7. 6 . Remedies; Rights Upon Event of Default. Upon the occurrence and during the continuance of an Event of Default under the Partnership Credit Agreement or Partnership Guarantee, Collateral Agent, for the equal and ratable benefit of and on behalf of the Secured Parties and the Funding Corporation, may, subject to the provisions of the Intercreditor Agreement and the other Financing Documents, do one or more of the following: .1 declare, without presentment, demand, protest or notice of any kind, all of which Pledgor hereby expressly waives, the entire amount of Obligations to be immediately due and payable, whereupon all of such Obligations declared due and payable shall be and become immediately due and payable; provided, however, if, with respect to the Partnership Guarantors, an Event of Default occurs pursuant to Section 5.1 of the Partnership Credit Agreement, then the acceleration provided for in this Section 6.1 shall be deemed to have been made upon the occurrence of such Event of Default without declaration or any other action by Collateral Agent; .2 upon notice to Pledgor, which notice need not be in writing, make such payments and do such acts as Collateral Agent may deem necessary to protect, perfect or continue the perfection of the Secured Parties' and the Funding Corporation's Security Interest in the Collateral, including, without limitation, paying, purchasing, contesting or compromising any Lien which is, or purports to be, prior to or superior to the Security Interest granted hereunder, and commencing, appearing or otherwise participating in or controlling any action or proceeding purporting to affect the Secured Parties' and the Funding Corporation's Security Interest in or ownership of the Collateral; .3 foreclose on the Collateral as herein provided or in any manner permitted by law and exercise any and all of the rights and remedies conferred upon the Secured Parties and the Funding Corporation by the Security Documents either concurrently or in such order as Collateral Agent may determine without affecting the rights or remedies to which the Secured Parties and the Funding Corporation may be entitled under any Security Documents. Pledgor hereby waives, to the extent permitted by applicable law, notice and judicial hearing in connection with Collateral Agent's taking 7 possession or collection, recovery, receipt, appropriation, repossession, retention, set-off, sale, leasing, conveyance, assignment, transfer or other disposition of or realization upon any or all of the Collateral, including, without limitation, any and all prior notice and hearing for any prejudgment remedy or remedies and any such right which Pledgor would otherwise have under the constitution or any statute or other law of the United States of America or of any state; .4 without notice, except as specified below, sell the Collateral, or any part thereof, in one or more parcels at public or private sale, at any of Collateral Agent's offices or elsewhere, at such time or times, for cash, on credit or for future delivery, and at a commercially reasonable price or prices and on other commercially reasonable terms. Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten (10) days' notice to Pledgor of the time and the place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. At any sale of the Collateral, if permitted by law, Collateral Agent may bid (which bid may be, in whole or in part, in the form of cancellation of indebtedness) for the purchase of the Collateral or any portion thereof for the account of Collateral Agent on behalf of the Secured Parties and the Funding Corporation. Collateral Agent shall not be obligated to make any sale of the Collateral regardless of notice of sale having been given. Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. Collateral Agent shall incur no liability as a result of the manner of sale of the Collateral, or any part thereof, at any private sale conducted in a commercially reasonable manner. Pledgor hereby waives, to the extent permitted by applicable law, any claims against Collateral Agent arising by reason of the fact that the price at which the Collateral, or any part thereof, may have been sold at a private sale was less than the price which might have been obtained at public sale or was less than the aggregate amount of the Obligations, even if Collateral Agent accepts the first offer received which Collateral Agent in good faith deems to be commercially reasonable under the circumstances and does not offer the Collateral to more than one offeree. To the full extent permitted by law, Pledgor shall have the burden of proving that any such sale of the Collateral was conducted in a commercially unreasonable manner. To the extent permitted by law, Pledgor hereby specifically waives all rights of redemption, stay or appraisal which it has or may have under any law now existing or hereafter enacted. Pledgor authorizes Collateral Agent, at any time and from time to time, to execute, in connection with a sale of the Collateral pursuant to the provisions of this Pledge Agreement, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral; .5 upon notice to Pledgor, register the Collateral in the name of Collateral Agent or its nominee as pledgee or otherwise take such action as Collateral Agent shall in its sole discretion deem necessary or desirable with respect to the Collateral, and Collateral Agent or its nominee may thereafter, in its sole discretion, without notice, exercise all voting, consent, managerial and other rights relating to the Collateral and exercise any and all rights of conversion, exchange, subscription or any other rights, privileges or options pertaining to the Collateral as if it were the absolute owner thereof, including, without limitation, all rights of Pledgor under the Partnership Agreement, including, without limitation, the right to (i) receive all permitted distributions, if any, made for the account of Pledgor under the Partnership Agreement and (ii) exchange any and all of the Collateral upon the merger, consolidation, reorganization, recapitalization or other readjustment of Leathers, all without liability except to account for property actually received by Collateral Agent, but Collateral Agent shall have no duty to exercise any of the aforesaid rights, privileges or options and shall not be responsible for any failure to do so or delay in so doing; and 8 .6 exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party after default under the Code. 7. Application of Proceeds. The net proceeds of any foreclosure, collection, recovery, receipt, appropriation, realization or sale of the Collateral shall be applied in the order of priority specified in the Intercreditor Agreement. If all Obligations and any other amounts due under this Pledge Agreement and the Intercreditor Agreement have been indefeasibly paid, satisfied and discharged in full, any surplus then remaining shall be paid to Pledgor, if it is lawfully entitled to receive the same or shall be paid to whomsoever a court of competent jurisdiction may direct. 8 . Security Interest Absolute. All the rights of Collateral Agent and any of the other Secured Parties and the Funding Corporation hereunder and the Security Interest and all obligations of Pledgor hereunder shall be absolute and unconditional irrespective of: .1. any lack of validity or enforceability of the Project Documents or the Partnership Agreement or the Financing Documents or any other agreement or instrument relating thereto; .2. any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to any departure from the Project Documents, the Partnership Agreement or the Financing Documents; .3. any exchange or release of any Collateral or any other collateral, or the non-perfection of any of the Security Interest, or any release or amendment or waiver of or consent to or departure from any guaranty, for all or any of the Obligations; .4. to the full extent permitted by law, any other circumstance that might otherwise constitute a defense available to, or a discharge of, Pledgor or any third party pledgor; or .5 the failure by any of the Pledgors to fulfill its obligations under this Pledge Agreement. 9. Collateral Agent Appointed Attorney-in-Fact. .1. Powers. Pledgor hereby irrevocably constitutes and appoints Collateral Agent and any officer or agent thereof, with full power of substitution, as Pledgor's true and lawful attorney-in-fact (which appointment as attorney-in-fact shall be coupled with an interest), with full authority in the place and stead of Pledgor and in the name of Pledgor or otherwise, from time to time upon the occurrence and during the continuance of any Event of Default under the Partnership Credit Agreement or the Partnership Guarantee in Collateral Agent's discretion, to take any action and to execute any and all documents and instruments which Collateral Agent may deem necessary or advisable to accomplish the purposes of this Pledge Agreement, without notice to Pledgor, including, without limitation: .1 to exercise all partnership rights, powers and privileges to the same extent Pledgor shall have been entitled under the Partnership Agreement and in 9 accordance with applicable law, including, without limitation, all voting rights of Pledgor as partner of Leathers; .2. to receive, endorse and collect all instruments made payable to Pledgor representing any interest payment or other distribution in respect of the Collateral or any part thereof and to give full discharge for the same and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by Collateral Agent for the purpose of collecting any and all of such dividends, payments or other distributions; .3. to pay or discharge taxes and liens levied or placed on the Collateral; and .4 . (a) to direct any party liable for any payment in respect of or arising out of any of the Collateral to make payment of any and all moneys due or to become due in connection therewith directly to Collateral Agent or as Collateral Agent shall otherwise direct, (b) to ask or make demand for, collect, receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral, (c) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any part thereof and to enforce any other right in respect of any Collateral, (d) to defend any suit, action or proceeding brought against Pledgor with respect to any Collateral, (e) to settle, compromise or adjust any suit, action or proceeding described in clause (d) above and, in connection therewith, to give such discharges or releases as Collateral Agent acting in good faith may deem appropriate and (f) generally, to sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though Collateral Agent were the absolute owner thereof for all purposes, and (g) to do, at Collateral Agent's option and at Pledgor's expense, at any time, or from time to time, all acts and things which Collateral Agent acting in good faith deems necessary to protect, preserve or realize upon the Collateral and the Security Interest granted herein and to effect the intent of this Pledge Agreement, all as fully and effectively as Pledgor might do. .2 . Other Powers. Pledgor further authorizes Collateral Agent, at any time and from time to time (i) to execute, in connection with any sale provided for hereunder, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral and (ii) to the full extent permitted by applicable law, to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral without the signature of Pledgor. 10 . Collateral Agent May Perform. Upon the occurrence and during the continuance of an Event of Default under the Partnership Credit Agreement or the Partnership Guarantee, Collateral Agent, without releasing Pledgor from any obligation, covenant or condition hereof, itself may make any payment or perform, or cause the performance of, any such obligation, covenant, condition or agreement or any other action in such manner and to such extent as Collateral Agent may deem necessary to protect, perfect or continue the perfection of the Secured Parties' and the Funding Corporation's Security Interest in the Collateral. Any costs or expenses incurred by Collateral Agent in connection with the foregoing shall be governed by the Indenture and the Financing Documents and constitute Obligations secured hereby. 10 11. No Duty on Collateral Agent's Part, Limitation on Collateral Agent's Obligations. .1. No Duty on Collateral Agent's Part. The powers conferred on Collateral Agent hereunder are solely to protect Collateral Agent's interests in the Collateral and shall not impose any duty upon it to exercise any such powers. Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers. .2. Limitations on Obligations. Without limiting the effectiveness of Section 30 hereof, anything herein to the contrary notwithstanding, Pledgor shall remain liable under the Partnership Agreement and any other Project Document or Financing Document to which it is a party to the extent set forth therein to perform all of its duties and obligations thereunder, to the same extent as if this Pledge Agreement had not been executed. The exercise by Collateral Agent of any of the rights or remedies hereunder shall not release Pledgor from any of its duties or obligations under the Partnership Agreement or any other Project Document or Financing Document to which it is a party. All of the Collateral is hereby assigned to Collateral Agent solely as security, and Collateral Agent shall have no duty, liability or obligation whatsoever with respect to any of the Collateral, unless Collateral Agent so elects in writing consistent with its rights under this Pledge Agreement. 12. Reasonable Care. Collateral Agent shall exercise the same degree of care hereunder as it exercises in connection with similar transactions for its own account. Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which Collateral Agent accords or would accord collateral held by Collateral Agent in similar transactions for its own account. Without limiting the generality of the foregoing and except as otherwise provided by applicable law, Collateral Agent shall not be required to marshall any collateral, including, without limitation, the Collateral subject to the Security Interest created hereby and any guaranties of the Obligations, or to resort to any item of Collateral or guaranties in any particular order; and all of Collateral Agent's rights hereunder and in respect of such Collateral and guaranties shall be cumulative and in addition to all other rights, however existing or arising. To the extent that Pledgor lawfully may, Pledgor hereby (a) agrees that it will not invoke any law relating to the marshalling of collateral which might cause delay in or impede the enforcement of Collateral Agent's rights under this Pledge Agreement or under any other instrument evidencing any of the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or guaranteed and (b) irrevocably waives the benefits of all Laws and any and all rights to equity of redemption or other rights of redemption that it may have in equity or at law with respect to the Collateral. 13. Role of Collateral Agent. The rights, duties, liabilities and immunities of Collateral Agent and its appointment and replacement hereunder shall be governed by the Intercreditor Agreement. 14.

Survival of Representations and Warranties. All agreements, representations and warranties made herein shall survive the execution and delivery of this Pledge Agreement and the other Financing Documents and repayment of the Obligations, and shall be deemed to be material and to have been relied upon by Collateral Agent and any of the other Secured Parties and the Funding Corporation, regardless of any investigation made by or on behalf of any of Collateral Agent and any of the other Secured Parties and the Funding Corporation.

Where provisions of any law or regulation resulting in such prohibition or unenforceability may be waived they are hereby waived by Pledgor and Collateral Agent to the full extent permitted by law so that this Pledge Agreement shall be deemed a valid, binding agreement, and the Security Interest created hereby shall constitute a continuing first lien on and first perfected security interest in the Collateral, in each case enforceable in accordance with its terms. 20.

Neither Collateral Agent, the Funding Corporation nor any other Secured Party, nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates (the "Exculpated Parties") shall be liable to Pledgor for any action taken or omitted to be taken by it or them under or in connection with this Pledge Agreement, the Partnership Agreement or any other Project Document or Financing Document to which Pledgor is a party, except for the Exculpated Parties' own gross negligence or willful misconduct, or responsible in any manner to any Person for any recitals, statements, representations or warranties made by Pledgor or any officer thereof contained in this Pledge Agreement, the Partnership Agreement or any other Project Document or Financing Document to which Pledgor is a party or in any certificate, report, statement or other document referred to or provided for in, or received by Collateral Agent, Funding Corporation or any other Secured Party under or in connection with, this Pledge Agreement, the Partnership Agreement or any other Project Document or Financing Document to which Pledgor is a party or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Pledge Agreement, the Partnership Agreement or any other Project Document or Financing Document to which Pledgor is a party or for any failure of Pledgor to perform any of the Obligations. Neither Collateral Agent, Funding Corporation nor any other Secured Party shall be under any obligation to any Person to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Pledge Agreement, the Partnership Agreement or any other Project Document or Financing Document to which Pledgor is a party, or to inspect the properties or records of Pledgor. .2 .

Notwithstanding the foregoing, if any amount shall be paid to Pledgor on account of such subrogation, reimbursement, indemnity, exoneration or contribution rights at any time, such amount shall be held by Pledgor in trust for the Secured Parties and the Funding Corporation, segregated from other funds of Pledgor, and shall be turned over to Collateral Agent for the benefit of the Secured Parties and the Funding Corporation, in the exact form received by Pledgor (duly endorsed by Pledgor to Collateral Agent for the benefit of the Secured Parties and the Funding Corporation, if required), to be applied against such amounts in such order as Collateral Agent may elect. 25.

This Pledge Agreement shall create a continuing assignment, pledge and first priority Security Interest in the Collateral, subject only to Permitted Liens, and shall remain in full force and effect for the benefit of Collateral Agent and the other Secured Parties and the Funding Corporation until all Obligations to be paid or performed by Partnership Guarantors under the Partnership Credit Agreement and the Partnership Guarantee have been paid and performed in full. Upon the happening of such event, the Security Interest granted hereby shall terminate. Upon such termination, Collateral Agent shall, upon the request and at the 14 expense of Pledgor, execute and deliver to Pledgor such documents as Pledgor shall reasonably request to evidence such termination or expiration. 28. Payments Set Aside. To the extent that Pledgor or the Partnership Guarantors or any other Person on behalf of Pledgor or the Partnership Guarantors makes a payment or payments to Collateral Agent and/or any other Secured Party, or Collateral Agent and/or any other Secured Party enforce the Security Interests or Collateral Agent exercises its right of set-off, and such payment or payments or the proceeds of such enforcement or set-off or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other party under any bankruptcy law, state or federal law, common law or equitable cause, then to the extent of such recovery, the Obligations or any part thereof originally intended to be satisfied, and this Pledge Agreement and all Liens, rights and remedies therefor, shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or set-off had not occurred. 29.
