"Affiliate" means, as to any Person, any other Person which, directly or indirectly, is in control of, is controlled by, or is under common control with, such Person. A Person shall be deemed to control another Person if the controlling Person possesses, directly or indirectly, the power to direct or cause the direction of the management and policies of the other Person, whether through the ownership of voting securities, membership interests, by contract, or otherwise.

"Agreement" means this credit agreement.

References to amounts on particular exhibits, schedules, lines, pages and columns of the Annual Statement are based on the format promulgated by the NAIC for 2005 Property and Casualty Company Annual Statements. If such format is changed in future years so that different information is contained in such items or they no longer exist, it is understood that the reference is to information consistent with that reported in the referenced item in the 2005 Annual Statement of such Insurance Subsidiary.

"Applicable Insurance Code" shall mean, as to any Insurance Subsidiary, the insurance code of any state where such Insurance Subsidiary is domiciled or doing insurance business and any successor statute of similar import, together with the regulations thereunder, as amended or otherwise modified and in effect from time to time.

Any adjustment in the Applicable Margin as a result of a change in the Company's implied counterparty credit rating by S&P and/or the implied rating of the Company's non-credit-enhanced,

senior unsecured long-term debt by ▇▇▇▇▇'▇ shall be effective as of the effective date of the change in such rating. In the event the rating by S&P and ▇▇▇▇▇'▇ do not fall in the same category provided above, the Applicable Margin shall be determined by adding one level to the lower of the two rating levels. In the event S&P does not provide an implied counterparty credit rating for the Company and ▇▇▇▇▇'▇ does not provide an implied rating of the Company's non-credit-enhanced, senior unsecured long-term debt, the Applicable Margin shall remain unchanged for a period of 90 days thereafter, during which period the Bank and the Company shall negotiate in good faith to agree upon a substitute means for determining the Applicable Margin.

All accrued commitment fees to, but not including the effective date of any reduction or termination of the Commitment, shall be paid on the effective date of such reduction or termination.

2.6 Optional Prepayments. Subject to Section 3.4, the Company may, at any time or from time to time, upon not less than two (2) Business Days' irrevocable notice to the Bank in the case of Eurodollar Rate Loans and upon same day irrevocable notice to the Bank in the case of Base Rate Loans, prepay Loans in whole or in part, in minimum amounts of $250,000 or any multiple of $10,000 in excess thereof (or, if less, the outstanding amount of such Loans).

incurred hereunder or incurred in the ordinary course of business), the net cash proceeds realized by the Company from such incurrence or issuance shall be applied first to prepay the outstanding principal amount of all Loans, together with accrued interest thereon, until such amounts are repaid in full, then to the use by the Company of such net cash proceeds for any other purpose allowed hereunder (it being understood that any prepayment made pursuant to this Section 2.7(b) shall not affect the Commitment in any respect).

(c) Equity Issuances.

2.8 Interest.

(a) Each Loan shall bear interest on the outstanding principal amount thereof from the applicable Borrowing Date at a rate per annum equal to the Eurodollar Rate or the Base Rate, as the case may be (and subject to the Company's right to convert to other Types of Loans under Section 2.4), plus the Applicable Margin.

(b) Interest on each Loan shall be paid in arrears on each Interest Payment Date. Interest shall also be paid on the date of any prepayment of Loans under Section 2.6 for the portion of the Loans so prepaid and upon payment (including prepayment) in full thereof and, during the existence of any Event of Default, interest shall be paid on demand of the Bank.

(c) If any amount payable by the Company under any Loan Document is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount (if the principal of a Loan) shall thereafter bear interest at a rate per annum determined by adding 2% per annum to the Applicable Margin then in effect for such Loan and, in the case of Obligations not subject to an Applicable Margin, at a rate per annum equal to the Base Rate plus 2%. Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand.

(d) Anything herein to the contrary notwithstanding, the obligations of the Company to the Bank hereunder shall be subject to the limitation that payments of interest shall not be required, for any period for which interest is computed hereunder, to the extent (but only to the extent) that contracting for or receiving such payment by the Bank would be contrary to the provisions of any law applicable to the Bank limiting the highest rate of interest that may be lawfully contracted for, charged or received by the Bank, and in such event the Company shall pay the Bank interest at the highest rate permitted by applicable law.

2.9 Commitment Fee. The Company shall pay to the Bank a commitment fee on the average daily unused portion of the Commitment, computed on a quarterly basis in arrears on the last Business Day of each calendar quarter based upon the daily utilization for that quarter as calculated by the Bank, equal to the applicable per annum rate set forth in the table below based on the Company's

implied counterparty credit rating by S&P and/or the implied rating of the Company's non-credit-enhanced, senior unsecured long-term debt by Moody's:

Debt Rating	Commitment Fee
BBB+/Baa1 or higher	.20	%
BBB/Baa2	.25	%
BBB-/Baa3	.30	%
BB+/Ba1 or lower	.35	%

Any adjustment to the commitment fee as a result of a change in the implied rating of the Company's implied counterparty credit rating by S&P and/or the Company's non-credit-enhanced, senior unsecured long-term debt by Moody's shall be effective as of the effective date of the change in such rating. In the event the rating by S&P and Moody's do not fall in the same category provided above, the commitment fee shall be determined by adding one level to the lower of the two rating levels. In the event S&P does not provide an implied counterparty credit rating for the Company and Moody's does not provide an implied rating of the Company's non-credit-enhanced, senior unsecured long-term debt, the commitment fee shall remain unchanged for a period of 90 days thereafter, during which period the Bank and the Company shall negotiate in good faith to agree upon a substitute means for determining the commitment fee. In the event such agreement is not reached in such 90-day period, the commitment fee shall, after such 90^th day, be .35%.

Such commitment fee shall accrue from the Closing Date to the Termination Date, and shall be due and payable quarterly in arrears on the last Business Day of each fiscal quarter of the Company commencing on March 30, 2007 through such Termination Date, with the final payment to be made on the Termination Date; provided, that in connection with any reduction or termination of the Commitment under Section 2.5, the accrued commitment fee calculated for the period ending on such date shall also be paid on the date of such reduction or termination, with the following quarterly payment being calculated on the basis of the period from such reduction or termination date to such quarterly payment date. The commitment fee provided in this subsection shall accrue at all times after the above-mentioned commencement date, including at any time during which one or more conditions in Article IV are not met.

2.10 Computation of Fees and Interest.

(a) All computations of interest for Base Rate Loans when the Base Rate is determined by the Bank's "prime rate" shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more interest being paid than if computed on the basis of a 365-day year). Interest and fees shall accrue during each period during which interest or such fees are computed from the first day thereof to the last day thereof.

(b) Each determination of an interest rate by the Bank shall be conclusive and binding on the Company unless the Company objects in writing to such determination within thirty days of having notice thereof. The Bank will, at the request of the Company, deliver to the Company a statement showing the quotations used by the Bank in determining any interest rate and the resulting interest rate.

2.11 Payments by the Company.

(a) All payments to be made by the Company shall be made without condition or deduction for any counterclaim, defense, recoupment or set-off. Except as otherwise expressly provided herein, all payments by the Company shall be made to the Bank at the Payment Office, and shall be made in dollars and in immediately available funds, no later than 3:00 p.m. (Dallas time) on the date specified herein. Any payment received by the Bank later than 3:00 p.m. (Dallas time) on

such date shall be deemed to have been received on the following Business Day and any applicable interest or fee shall continue to accrue.

(b) Subject to the provisions set forth in the definition of "Interest Period" herein, whenever any payment is due on a day other than a Business Day, such payment shall be made on the following Business Day, and such extension of time shall in such case be included in the computation of interest or fees, as the case may be.

3.2 Illegality.

(a) If the Bank determines that the introduction of any Requirement of Law, or any change in any Requirement of Law, or in the interpretation or administration of any Requirement of Law, has made it unlawful, or that any central bank or other Governmental Authority has asserted that

(c) Before giving any notice under this Section, the Bank shall designate a different Lending Office with respect to its Eurodollar Rate Loans if such designation will avoid the need for giving such notice or making such demand and will not, in the judgment of the Bank, be illegal or otherwise disadvantageous to the Bank.

(a) If the Bank determines that, due to either (i) the introduction of or any change (other than any change by way of imposition of or increase in reserve requirements included in the calculation of the Eurodollar Rate or in respect of the assessment rate payable by the Bank to the FDIC for insuring U.S. deposits) in or in the interpretation of any law or regulation or (ii) the compliance by the Bank with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to the Bank of agreeing to make or making, funding or maintaining any Eurodollar Rate Loans, then the Company shall be liable for, and shall from time to time, upon demand, pay to the Bank, additional amounts as are sufficient to reimburse the Bank for the costs associated with such increased costs.

For purposes of calculating amounts payable by the Company to the Bank under this Section and under Section 3.3(a), each Eurodollar Rate Loan made by the Bank (and each related reserve, special deposit or similar requirement) shall be conclusively deemed to have been funded at the Eurodollar Base Rate used in determining the Eurodollar Rate for such Eurodollar Rate Loan by a matching deposit or other borrowing in the interbank eurodollar market for a comparable amount and for a comparable period, whether or not such Eurodollar Rate Loan is in fact so funded.

3.5 Inability to Determine Rates If the Bank determines that for any reason adequate and reasonable means do not exist for determining the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan, or that the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan does not adequately and fairly reflect the cost to the Bank of funding such Loan, the Bank will promptly so notify the Company.

Company's prior written consent. A Participant that is not a "United States person" within the meaning of Section 7701(a)(30) of the Code shall not be entitled to the benefits of Section 3.1 unless the Company is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Company, to provide to the Bank such tax forms prescribed by the IRS as are necessary or desirable to establish an exemption from, or reduction of, U.S. withholding tax.

any breach of, or constitute a default under, any indenture, mortgage, deed of trust, credit agreement, loan agreement or other agreement, contract or instrument binding on it, or (iii) result in the creation or imposition of (or the obligation to create or impose) any Lien (except for Permitted Liens) upon any of the property or assets of the Company pursuant to the terms of any of the indentures, mortgages, deeds of trust, credit agreements, loan agreements or other agreements, contracts or instruments to which the Company is a party, or (iv) contravene or conflict with any of the articles of incorporation or by-laws of the Company.
