If the proposed offering upon which the holders of Registrable Securities exercise their piggyback rights shall be an underwritten offering, then, in the event that the managing underwriter or managing underwriters of such offering advise the Partnership and the Holders electing to exercise piggyback rights in writing that in their opinion the inclusion of all or some of such Holder's Partnership Securities would adversely and materially affect the success of the offering, the Partnership shall include in such offering only that number or amount, if any, of securities held by such Holder which, in the opinion of the managing underwriter or managing underwriters, will not so adversely and materially affect the offering. The Partnership will cause a demand registration to remain effective for 180 days, unless all securities covered by such registration have been sold (Section 2.1(a)(ii). The Partnership may postpone a demand registration 90 days if such postponement is in the best interests of the Partnership and its partners due a pending transaction, investigation or event (Section 2). In the event a demand registration involves an underwritten offering, the underwriter(s) shall be selected by the Holders and reasonably acceptable to the Partnership (Section 2.1(d)). Registration rights will not terminate until the later of (i) December 31, 2010, (ii) 2 years following the withdrawal of the General Partner as the general partner of the Partnership or (iii) the termination of registration rights granted to the General Partner and its affiliates (Section 2.3). The Partnership represents and covenants that any registration statement covering sales by a Holder pursuant to the Registration Rights Agreement will not contain material misstatements or omissions. The obligation of the Partnership to amend or supplement a prospectus to keep a registration statement available for use may be suspended for up to 30 consecutive and 60 non-consecutive days if the amendment or supplement would require the disclosure of information that the Partnership has a bona fide business purpose for keeping confidential (Section 3(b)). The Holders will agree to market-standoff for a period of 180 days from the date of request to standoff (Section 5(a)). Holders will not be required to indemnify, provide contribution to, the Partnership for losses arising from the registration of securities pursuant to the Registration Rights Agreement (Section 6(b) and Section 6(d)). Each Holder represents and covenants that any information provided by such Holder with respect to a registration pursuant to the Registration Rights Agreement will not contain material misstatements or omissions (Section 6(b)). Each Holder may assign or subdivide its rights pursuant to the Registration Rights Agreement directly to no more than 2 Persons without prior written consent of the Partnership (Section 8). The Partnership agrees to enter into customary underwriting agreements, cooperate in any due diligence conducted by underwriters, and deliver or cause to be delivered to the Holders and the underwriters, if any, any certificates, opinions or comfort letters customarily required. The Partnership agrees to facilitate the delivery of the Registrable Securities upon any sale by a Holder pursuant to the Registration Rights Agreement. The undersigned parties agree that the foregoing will be effective for all purposes under the Combination Agreement and the agreements contemplated by it. The undersigned parties shall amend and restate the documents referred to above that have previously been executed and will revise such documents that are to be executed at closing, each in a manner consistent with the foregoing, and shall execute such documents as amended and restated or revised, as applicable, at the closing of the combination transaction.

Raley EXHIBIT A The following shall be inserted as a new Section 13.4 of the Partnership Agreement and the subsequent sections shall be renumbered. SECTION 13.4. Annual Meetings. (a) Beginning in 2004, an annual meeting of Limited Partners shall be held for the election of the members of the Advisory Committee, on the first Wednesday of May if not a legal holiday, and if a legal holiday then on the next business day following, at 10:00 a.m., or at such date and time as may be designated by resolution of the Board of Managers from time to time and stated in the notice of the meeting, at which the Limited Partners shall by a plurality elect the members of the Advisory Committee and to transact such other business as is properly brought before the meeting in accordance with this Agreement. Annual meetings of Limited Partners shall be held at such place, either within or without the State of Delaware, as shall be designated from time to time by the Board of Managers and stated in the notice of the meeting. Written notice of the annual meeting stating the place, date and hour of the meeting shall be given to each Limited Partner entitled to vote at such meeting not less than ten (10) nor more than sixty (60) days before the date of the meeting. (b) To be properly brought before an annual meeting, business must be either (i) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Managers, (ii) otherwise properly brought before the meeting by or at the direction of the Board of Managers, or (iii) otherwise (A) be properly requested to be brought before the meeting by a Limited Partner of record entitled to vote in the election of the members of the Advisory Committee generally and (B) constitute a proper subject to be brought before the meeting. In order for business (other than the election of the members of the Advisory Committee) to be properly brought before the annual meeting of Limited Partners by a Limited Partner, the business must be legally proper, and written notice of such Limited Partner's intent to bring such matter before the annual meeting of Limited Partners must be delivered, either by personal delivery or by United States mail, postage prepaid, to the General Partner of the Partnership. Such notice must be received by the General Partner not later than 60 days in advance of such meeting if such meeting is to be held on a day which is within 30 days preceding the anniversary of the previous year's annual meeting, or 90 days in advance of such meeting if such meeting is to be held on or after the anniversary of the previous year's annual meeting. A Limited Partner's notice to the General Partner shall set forth as to each matter the Limited Partner proposes to bring before the annual meeting of Limited Partners: (i) a brief description of the business desired to be brought before the meeting and the reasons for conducting such business at the meeting, (ii) the name and address, as they appear on the Partnership's books, of the Limited Partner proposing such business, (iii) the class and number of Limited Partnership Interests of the Partnership which are owned by such Limited Partner and (iv) any material interest of the Limited Partner in such business. No business brought by a Limited Partner shall be conducted at the annual meeting of Limited Partners except in accordance with the procedures set forth in this Section 13.4(b). The filing of a Limited Partner notice as required by this Section 13.4(b) shall not, in and of itself, constitute the bringing of the business described therein before the annual meeting. The chairman of the meeting shall, if the facts warrant, determine that (1) the business proposed to be brought before the meeting is not a proper subject therefor and/or (2) such business was not properly brought before the meeting in accordance with the provisions hereof, and if he should so determine, he shall declare to the meeting that (1) the business proposed to be brought before the meeting is not a proper subject thereof and/or (2) such business was not properly brought before the meeting and shall not be transacted. (c) Nominations for the election of the members of the Advisory Committee shall be made by the General Partner and may be made by any Limited Partner entitled to vote for the election of the members of the Advisory Committee. Any Limited Partner entitled to vote for the election of the members of the Advisory Committee at a meeting (i.e., any Limited Partner of record) may nominate persons for election as a member of the Advisory Committee only if written notice of such Limited Partner's intent to make such nomination is given, either by personal delivery or by United States mail, postage prepaid, to the General Partner of the Partnership not later 90 days in advance of such meeting. Each such notice shall set forth: (1) the name and address of the Limited Partner who intends to make the nomination of the person or persons to be nominated; (2) the name of the person or persons to be nominated; (3) a representation that the Limited Partner is a holder of record of Limited Partnership Interests of the Partnership entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice; (4) a description of all arrangements or understandings between the Limited Partner and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the Limited Partner; (5) such other information regarding each nominee proposed by such Limited Partner as would have been required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission had each nominee been nominated, or intended to be nominated, by the General Partner; and (6) the written consent of each nominee to serve as a member of the Advisory Committee if so elected. The filing of a Limited Partner notice as required by this Section 13.4(c) shall not, in and of itself, constitute the making of the nomination(s) described therein. The chairman of the meeting may refuse to acknowledge the nomination of any person not made in compliance with the foregoing procedure. (d) Newly created memberships on the Advisory Committee resulting from any increase in the authorized number of members of the Advisory Committee may be filled by the General Partner in accordance with the limited liability company agreement of its general partner. In the event of a vacancy on the Advisory Committee, the member of the general partner of the General Partner that held the appointment or nomination right, as applicable, with respect to such vacating member shall have the right, pursuant to the limited liability company agreement of the general partner of the General Partner, to nominate, and cause the General Partner to appoint, a replacement member of the Advisory Committee. A member of the Advisory Committee appointed to fill a newly created membership or a vacancy in accordance with the foregoing shall serve until the next annual meeting of limited partners. (e) In addition to any other applicable requirements, for a Limited Partner proposal to be considered for inclusion in the Partnership's proxy statement for the annual meeting, the Limited Partner must have satisfied all of the conditions set forth in Rule 14a-8 promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or any successor rule thereto (the "Proxy Rules"), including particularly the requirement that the Limited Partner give timely written notice of the proposal to the Partnership. The following shall be inserted into Section 13.10, as renumbered. Members of the Advisory Committee shall be elected by a plurality of the votes of the Outstanding Limited Interests present in person or by proxy at the meeting and entitled to vote on the election of the members of the Advisory Committee. The following shall be inserted into Section 13.5, as renumbered.

No business brought by a Limited Partner shall be conducted at the annual meeting of Limited Partners except in accordance with the procedures set forth in this Section 13.5. Notwithstanding anything to the contrary, the Limited Partners shall only be entitled to call one special meeting every twelve (12) months. The following shall be inserted into Section 13.11, as renumbered. Notwithstanding anything in this Agreement to the contrary, no business shall be conducted at a meeting except in accordance with the procedures and conditions set forth in this Article XIII, and the Proxy Rules; provided, however, that nothing in this Article XIII or the Proxy Rules shall be deemed to preclude discussion of any business properly brought before a meeting. The chairman of the meeting shall, if the facts warrant, determine and declare to the meeting that business was not properly brought before the meeting in accordance with the provisions of this Article XIII, and if he should so determine, he shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted.
