(ff) The Company is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which they are engaged. The Company has no reason to believe that it will not be able to renew its 14 existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers at a cost that would not have a Material Adverse Effect. (gg) The Company maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management's general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management's general or specific authorization and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

Under applicable zoning and use laws, ordinances, rules and regulations, the Riviera Black Hawk may be used for the purposes contemplated in the Offering Circular, the Indenture and the Collateral Documents, and all necessary approvals have been obtained therefor, except for approvals which the Company would not customarily possess at the date hereof but which will be obtained in the ordinary course of development of the Riviera Black Hawk. (jj) Upon execution and delivery of the Collateral Documents (other than the Pledge Agreement and the Pledge and Assignment Agreement) by the parties thereto and completion of the filings and recordings contemplated thereby, the security interests created for the benefit of the Trustee and the holders of the Notes pursuant to the Collateral Documents (other than the Pledge Agreement and the Pledge and Assignment Agreement) will constitute valid, perfected first priority security interests in the collateral subject thereto subject to "Permitted Liens" as defined in the Indenture. (kk) All notice filings to be made pursuant to the Collateral Documents (including without limitation all financing statements) are in proper form to be filed in order to perfect a security interest in the collateral described therein. (ll) At all times after execution and delivery of the Pledge and Assignment and the Account Agreement (as defined therein) and completion of the filings and recordings contemplated thereby, the security interests created for the benefit of the Trustee and the holders of the Notes pursuant to the Pledge and Assignment Agreement will constitute valid, perfected 15 first priority security interests in the collateral subject thereto. (mm) The Initial Purchaser has been furnished with a copy of the plans and specifications for the construction of the improvements of the Riviera Black Hawk and other necessary expenditures. Such plans and specifications are satisfactory to the Company.

The Company is not aware of any material defects in such improvements. In addition, each of the other amounts set forth in the section entitled "Sources and Uses of Funds" under the caption "Use of Proceeds" in the Offering Circular are based upon reasonable assumptions as to all matters material to the estimates set forth therein and are not expected by the Company to exceed the amounts set forth for such items. (nn) The Company has prepared the Construction Disbursement Budget (as defined in the Cash Collateral and Disbursement Agreement) and the Construction Schedule (as defined in the Cash Collateral and Disbursement Agreement) and has developed the assumptions on which the Construction Disbursement Budget and Construction Schedule are based. The Construction Disbursement Budget and the Construction Schedule are, as of the Closing Date, (i) in the opinion of the Company, based on reasonable assumptions as to all legal and factual matters material to the estimates set forth therein, (ii) call for the construction of the Minimum Facilities (as defined in the Indenture) on or prior to the Operating Deadline and (iii) consistent with the provisions of the Indenture and the other Operative Documents. (oo) The Company acknowledges that the Initial Purchaser and, for purposes of the opinions to be delivered to the Initial Purchaser pursuant to Section 10 hereof, counsel to the Company and counsel to the Initial Purchaser, will rely upon the accuracy and truth of the foregoing representations and hereby consents to such reliance. 7.

Indemnification (a) The Company and Riviera Holdings (collectively, the "Riviera Entities"), jointly and severally, agree to indemnify and hold harmless the Initial Purchaser, its directors, its officers and each person, if any, who controls such Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and judgments (including, without limitation, any legal or other expenses incurred in connection with investigating or defending any matter, including any action, that could give rise to any such losses, claims, damages, liabilities or judgments) caused by any untrue statement or alleged untrue statement of a material fact contained in the Final Offering Circular (or any amendment or supplement thereto), the Preliminary Offering Circular or any Rule 144A Information provided by the Company to any holder or prospective purchaser of Series A Notes pursuant to Section 5(i) hereof or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to the Initial Purchaser furnished in writing to the Company by such Initial Purchaser. (b) The Initial Purchaser agrees to indemnify and hold harmless each of the Riviera Entities, and their respective directors and officers and each person, if any, who controls (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act) any of the Riviera Entities, to the same extent as the foregoing indemnity from the Riviera Entities to the Initial 20 Purchaser but only with reference to information relating to the Initial Purchaser furnished in writing to the Company by the Initial Purchaser expressly for use in the Preliminary Offering Circular or the Final Offering Circular, which includes only the first sentence of the third paragraph, the third sentence of the fourth paragraph and the fifth paragraph, in each case under the caption "Plan of Distribution" appearing of page 98 of the Final Offering Circular. (c) In case any action shall be commenced involving any person in respect of which indemnity may be sought pursuant to Section 9(a) or 9(b) (the "indemnified party"), the indemnified party shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing and the indemnifying party shall assume the defense of such action, including the employment of counsel reasonably satisfactory to the indemnified party and the payment of all fees and expenses of such counsel, as incurred (except that in the case of any action in respect of which indemnity may be sought pursuant to both Sections 9(a) and 9(b), the Initial Purchaser shall not be required to assume the defense of such action pursuant to this Section 9(c), but may employ separate counsel and participate in the defense thereof, but the fees and expenses of such counsel, except as provided below, shall be at the expense of the Initial Purchaser). Any indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified party unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense of such action or employ counsel reasonably satisfactory to the indemnified party or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and the indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party). In any such case, the indemnifying party shall not, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties and all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Initial Purchaser, in the case of the parties indemnified pursuant to Section 9(a), and by the Riviera Entities, in the case of parties indemnified pursuant to Section 9(b). The indemnifying party shall indemnify and hold harmless the indemnified party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action (i) effected with its written consent or (ii) effected without its written consent if the settlement is entered into more than twenty business days after the indemnifying party shall have received a request from the indemnified party for reimbursement for the fees and expenses of counsel (in any case where such fees and expenses are at the expense of the indemnifying party) and, prior to the date of such settlement, the indemnifying party shall have failed to comply with such reimbursement request. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened action in respect of which the indemnified party is or could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes 21 an unconditional release of the indemnified party from all liability on claims that are or could have been the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of the indemnified party. (d) To the extent the indemnification provided for in this Section 9 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial Purchaser on the other hand from the offering of the Series A Notes or (ii) if the allocation provided by clause 9(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 9(d)(i) above but also the relative fault of the Company, on the one hand, and the Initial Purchaser, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand and the Initial Purchaser, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering of the Series A Notes (after underwriting discounts and commissions, but before deducting expenses) received by the Company, and the total discounts and commissions received by the Initial Purchaser bear to the total price to investors of the Series A Notes, in each case as set forth in the table on the cover page of the Offering Circular. The relative fault of the Company, on the one hand, and the Initial Purchaser, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Initial Purchaser, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. (e) The Riviera Entities and the Initial Purchaser agree that it would not be just and equitable if contribution pursuant to Section 9(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such indemnified party in connection with investigating or defending any matter, including any action, that could have given rise to such losses, claims, damages, liabilities or judgments. Notwithstanding the provisions of this Section 9, the Initial Purchaser shall not be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser exceeds the amount of any damages which the Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (f) The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in 22 equity. 10.
