The indemnification obligation under this Section 3.1 shall continue until the expiration of the statute of limitations (including extension) relating to the filing by the Predecessor Companies of all Tax Returns relating to the Formation Transactions.

Section 3.2 Indemnification by CFSI LLC for an NOL Limitation Event.

(a) Upon the occurrence of an NOL Limitation Event, CFSI LLC or its successor shall indemnify, defend and hold harmless the Partnership Entities for any increases in federal, state and local income Tax liabilities of the Partnership Entities attributable to the reduction or elimination of NOL Carryovers otherwise available to the Partnership Entities on the Closing Date. The indemnification obligations under this Section 3.2 shall continue until the expiration of the statute of limitations (including extension) relating to the filing by the Predecessor Companies of all Tax Returns relating to the Formation Transactions.

(b) The indemnification obligations under this Section 3.2 shall be an amount equal to:

(i) The positive difference, if any, of (A) the Actual Aggregate Income Tax Due of the Partnership Entities and (B) the Notional Aggregate Income Tax Due of the Partnership Entities. The indemnification obligations under this Section 3.2(b)(i) shall be calculated, measured and applied for each taxable year of the Partnership Entities, including taxable years prior to, during and after the taxable year in which the NOL Limitation Event occurs, until the expiration of the NOL Carryover Period (measured from the earliest period affected by the NOL Limitation Event); or

(ii) At the option of CFSI LLC, CFSI LLC may make a one-time payment in satisfaction of its indemnification obligation under this Section 3.2 equal to the

5

present value of the positive difference, if any, of (A) the Partnership Tax Model Projected Income Tax Due and (B) the Partnership Tax Model Revised Projected Income Tax Due assuming (X) the NOL Carryover would otherwise have been calculated, measured and applied in the manner, amount and time period as shown in the Partnership Tax Model and (Y) the amount of such positive difference, if any, is adjusted using a discount rate of [_]% per annum compounded [quarterly] from the last day of each calendar year 2004 through 2008 shown on the Partnership Tax Model to the Closing Date.

Section 3.3 Indemnification by the Partnership Entities. The Partnership Entities shall, jointly and severally, indemnify, defend and hold harmless the MDC Entities from and against all Losses suffered or incurred by the MDC Entities arising out of or relating to the Conveyed Assets, whether before, on or after the Closing Date, except with respect to matters for which the Partnership Entities are entitled to indemnification therefor under Section 3.1 and Section 3.2 (without regard to any limitations as to time).

Section 3.4 Indemnification Procedures.

(a) As used in this Section 3.4, the term “Indemnifying Party” refers to CFSI LLC, in the case of any indemnification obligation arising under Section 3.1 or Section 3.2, and to the Partnership Entities, in the case of any indemnification obligation arising under Section 3.3, and the term “Indemnified Party” refers to the Partnership Entities, in the case of any indemnification obligation arising under Section 3.1 or Section 3.2, and to the MDC Entities, in the case of any indemnification obligation arising under Section 3.3.

(b) The Indemnified Party agrees that promptly after it becomes aware of facts giving rise to a claim for indemnification under Section 3.1 or Section 3.3, it will provide notice thereof in writing to the Indemnifying Party, specifying the nature of and specific basis for such claim.

(c) Under Section 3.2, the Indemnifying Party shall promptly notify the Indemnified Party upon the occurrence of any inquiry from or instigation of proceedings by a Governmental Authority that could reasonably be expected to lead to or result in an NOL Limitation Event. Thereafter, the Indemnifying Party agrees to keep the Indemnified Party informed as to the status of such inquiry or proceeding. Upon the occurrence of an NOL Limitation Event, the Indemnifying Party shall promptly provide notice thereof in writing to the Indemnified Party. The Indemnifying Party shall have (30) thirty days from the date of the occurrence of an NOL Limitation Event to deliver to the Indemnified Party its written notice to elect to make a one-time payment pursuant to Section 3.2(b)(ii) in satisfaction of its indemnification obligation under Section 3.2. The Indemnified Party shall then have (90) ninety days to deliver to the Indemnifying Party its good faith written notice of the amount to be indemnified against under Section 3.2(b)(ii) with respect to such taxable periods. If the Indemnifying Party does not elect to make a one-time payment pursuant to Section 3.2(b)(ii) and to the extent the indemnification obligation under Section 3.2 relates to taxable periods prior to the taxable period in which the NOL Limitation Event occurs, the Indemnified Party shall then have (90) ninety days to deliver to the Indemnifying Party its good faith written notice of the amount to be indemnified against under Section 3.2(b)(i) with respect to such prior taxable period. To the extent the indemnification obligation under Section 3.2 relates to taxable periods

6

during or after the taxable period in which the NOL Limitation Event occurs, the Indemnified Party shall then have (120) one hundred twenty days after the end of each such taxable year to deliver to the Indemnifying Party its good faith written notice of the amount to be indemnified against under Section 3.2(b)(i) with respect to such taxable periods. Receipt of any such notices setting out the amounts to be indemnified against by the Indemnifying Party under Section 3.2(b)(i) or Section 3.2(b)(ii) shall be conclusive against the Indemnifying Party in all respects (20) twenty days after receipt by the Indemnifying Party of such notices and the Indemnifying Party shall promptly pay the Indemnified Party the amount to be indemnified against under Section 3.2(b)(i) or Section 3.2(b)(ii), unless within such period the Indemnifying Party sends the Indemnified Party a notice disputing the amount of such claim. Such notice of dispute shall describe the basis for such objection and the amount of the claim as to which the Indemnifying Party does not believe should be subject to indemnification. Upon receipt of any such notice of objection, both the Indemnified Party and the Indemnifying Party shall use all reasonable efforts to cooperate and arrive at a mutually acceptable resolution of such dispute with the next (30) thirty days. If a mutually acceptable resolution cannot be reached between the Indemnified Party and the Indemnifying Party within such 30-day period, the matter shall be referred to the CPA Mediator. Within (30) thirty days after the date of such referral, the CPA Mediator shall render its decision with respect to the differences, and such decision shall be final and binding on the Indemnified Party and the Indemnifying Party.

(d) The Indemnifying Party shall have the right to control, at its sole cost and expense, all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification provisions under this Article III, including, without limitation, the selection of counsel, determination of whether to appeal any decision of any Governmental Authority and the settling of any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent of the Indemnified Party (which consent shall not be unreasonably withheld) unless it includes a full release of the Indemnified Party from such matter or issues, as the case may be.

(e) The Indemnified Party agrees to cooperate fully with the Indemnifying Party with respect to all aspects of the defense of any claims covered by the indemnification provisions under this Article III, including, without limitation, the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection with such defense, the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party that the Indemnifying Party considers relevant to such defense and the making available to the Indemnifying Party of any employees of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records, and other information furnished by the Indemnified Party pursuant to this Section 3.4. In no event shall the obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article III; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as

7

to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control over such defense.

(f) In determining the amount of any loss, cost, damage or expense for which the Indemnified Party is entitled to indemnification under this Agreement, (i) the gross amount of the indemnification will be reduced by (A) any insurance proceeds realized by the Indemnified Party, and such correlative insurance benefit shall be net of any incremental insurance premium that becomes due and payable by the Indemnified Party as a result of such claim and (B) all amounts recovered by the Indemnified Party under contractual indemnities from third Persons and (ii) the extent of the Losses suffered by the Indemnified Party with respect to claims under Section 3.1 shall be established by the entry of a final nonappealable judgment or decree by a court or the execution of a final and binding settlement agreement with any Governmental Authority having jurisdiction thereof.

(g) The date on which written notification of a claim for indemnification is received by the Indemnifying Party shall determine whether such claim is timely made within the limitations specified in Section 3.1. No claim for indemnification pursuant to Section 3.1 shall be brought or made unless, prior to thirty (30) days after the expiration of the applicable time period set forth in Section 3.1, the Indemnified Party shall have delivered to the Indemnifying Party a good faith written notice to the effect that the Indemnified Party has incurred Losses entitled to be indemnified against under Section 3.1, which notice specifies in reasonable detail the amount of such Losses and the nature and specific basis of such claim.

Section 3.5 Existence of CFSI LLC. CFSI LLC shall remain in existence until the later of (i) the expiration of the statute of limitations (including extension) relating to the filing by the Predecessor Companies of all Tax Returns relating to the Formation Transactions or (ii) the ultimate resolution of an inquiry from or instigation of proceedings by a Government Authority for which notice was required to be given by the Indemnifying Party pursuant to Section 3.4(c).
