A. All Tax Items shall be allocated to all Record Holders in accordance with their respective Units in the Company. All Outstanding Units shall be treated equally.

B. Notwithstanding anything to the contrary in this Section 4.2, any Capital Gain recognized by the Company shall be allocated first to those Record Holders, if any, to take into account the provisions of Section 4.2.D below, next to those Record Holders who have negative Capital Accounts to restore such Capital Accounts to zero and further, to any Record Holders in order to cause such Capital Accounts of all Record Holders to be equalized. The purpose of this method of allocation is to give “substantial economic effect” to the allocations and Capital Accounts hereunder in accordance with Section 704(b) of the Code and Treasury Regulations thereunder.

C. If during any fiscal year of the Company, any Record Holder unexpectedly receives an adjustment, allocation, or distribution of the type described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4),(5), or (6), that Record Holder shall be allocated items of Income in an amount and manner sufficient to eliminate that Record Holder’s deficit Capital Account balance as quickly as possible.

The Members shall have the power to make such elections, adopt such conventions, and allocate Capital Gain, Income and Loss as each of them deems appropriate to comply with Section 704(c) of the Code and any Treasury Regulations promulgated thereunder and to preserve, to the extent possible, uniformity of the Units. Any items allocated under this Section 4.2.D shall not be debited or credited to Capital Accounts to the extent that item is already taken into account (upon formation or otherwise) in determining a Record Holder’s Capital Account.

E. Upon the transfer of a Unit, Income, Capital Gain and Loss attributable to the transferred Unit, shall, for federal income tax purposes, be allocated to the owners of such Unit on the basis of the Income or Loss for each month that such Person was the owner of such Units, determined on an interim closing of the books method.

Anything herein to the contrary notwithstanding, except as otherwise expressly agreed in writing, a Member shall not be personally liable for any debts, liabilities, or obligations of the Company, whether to the Company, to any of the other Members, to creditors of the Company, or to any other Person. The failure of the Company to observe any formalities or requirements relating to the exercise of its powers or management of its business or affairs under the Agreement or the Act shall not be grounds for imposing personal liability on the Members for liabilities of the Company.
