AGREEMENT

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by each of the parties hereto, the parties agree as follows:

1.           Amendments.

a.           The definition of “Book Value” contained in Article 1 of the Operating Agreement is hereby amended and restated in its entirety and replaced with the following:

““Book Value” means, with respect to any Company asset, the adjusted basis of such asset for federal income tax purposes, except as follows:

b.           Section 4.4 of the Operating Agreement is hereby amended and restated in its entirety and replaced with the following:

“4.4 Tax Allocations; Code Section 704(c). The income, gains, losses, deductions and expenses of the Company shall be allocated, for federal, state and local income tax purposes, among the Members in accordance with the allocation of such income, gains, losses, deductions and expenses among such Members for computing their Capital Accounts, except that if any such allocation is not permitted by the Code or other applicable law, the Company’s subsequent income, gains, losses, deductions and expenses shall be allocated among the Members for tax purposes to the extent permitted by the Code and other applicable law, so as to reflect as nearly as possible the allocation set forth herein in computing their Capital Accounts.

Notwithstanding the previous sentence, such items shall be allocated among the Members in a different manner to the extent required by Code Section 704(c) and the Treasury Regulations thereunder (dealing with contributed property), Treasury Regulations Sections 1.704-1(b)(2)(iv)(f) (dealing with property having a book value different than its tax basis) and 1.704-1(b)(4)(ii) (dealing with tax credit items). The Members agree that, for purposes of Section 704(c) of the Code, with respect to tax items attributable to any book-tax differences (whether from property contributed to the Company or resulting from revaluations of Company property), the Company will use the “remedial method” as described in Treasury Regulations Section 1.704-3(d) unless the Board directs (subject to Section 6.12.2.4) the Company to use a method other than the remedial method. Allocations pursuant to this Section 4.4 are solely for purposes of federal, state and local taxes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of profits, losses, other items or distributions pursuant to any provisions of this Agreement.”

c.           Section 6.12.2.3 of the Operating Agreement is hereby deleted, and the following new Sections 6.12.2.3, 6.12.2.4 and 6.12.2.5 are added:

“6.12.2.3             Determining that an adjustment to Book Value for one of the events listed in Section (ii)a of the definition of Book Value is not necessary to reflect the relative economic interests of the Members in the Company.

6.12.2.4               Directing the Company to use a method of allocation other than the “remedial method” with respect to tax items attributable to any book-tax differences under Section 4.4.

6.12.2.5               Entering into an agreement to do any of the foregoing set forth in this Section 6.12.2.”

2.           Except as expressly provided herein, nothing in this Amendment shall be deemed to waive or modify any of the other provisions of the Operating Agreement. In the event of any conflict between the Operating Agreement, any previous amendment of the Operating Agreement, this Amendment and any subsequent amendment, the document later in time shall prevail.

3.           This Amendment shall be binding upon and shall inure to the benefit of the successors in interest of the parties hereto.

IN WITNESS WHEREOF, the undersigned has caused this Amendment to be executed as of the date first hereinabove set forth.
