Code Xxx. §4A-101 et seq.), as in effect from time to time (the “Act”), and engaging in any and all activities necessary or incidental to accomplish the foregoing.

3. Term. The existence of the Company commenced on the date a Articles of Organization was filed with the office of the Maryland Department of Assessments and Taxation under and pursuant to the Act and shall continue until the Company is dissolved pursuant to Section 13 of this Agreement.

4. Capitalization.

(a) Each Member’s interest in the Company, including such Member’s interest, if any, in the capital, income, gains, losses, deductions and expenses of the Company, and the right to vote, if any, on matters affecting the Company or such Member’s interest therein, as provided by the Act or this Agreement, shall be represented by units held by such Member.

(b) All Units issued hereunder shall be issued in uncertificated form unless otherwise determined by the Members.

The Members shall determine the terms and conditions governing the issuance of such Additional Interests, including the number and designation of such Additional Interests, the preference (with respect to distributions) over any other membership interests and any required contributions in connection therewith. Upon the issuance or sale of Additional Interests, the Members or an authorized Officer shall amend Schedule 1 without further vote, act or consent of any other Person to reflect the issuance or sale of such Additional Interests and the resulting Percentage Interests of the Members.

6. Additional Members. In order for a Person to be admitted as a Member of the Company with respect to an Additional Interest: (a) such Person shall have delivered to the Company a written undertaking to be bound by the terms and conditions of this Agreement and shall have delivered such documents and instruments as the Members determine to be necessary or appropriate in connection with the issuance of such Additional Interest to such Person or to effect such Person’s admission as a Member; and (b) the Members or an authorized Officer shall amend Schedule 1 without the further vote, act or consent of any other Person to reflect such new Person as a Member.

(i) The Company shall maintain a capital account (each, a “Capital Account”) for each Member in accordance with Treasury Regulations Section l.704-l(b)(2)(iv). For this purpose, the Company may, upon the occurrence of any of the events specified in Treasury Regulations Section 1.704-1(b)(2)(iv)(f), increase or decrease the Capital Accounts in accordance with the rules of such regulation and Treasury Regulations Section 1.704-l(b)(2)(iv)(g) to reflect a revaluation of Company property. Items of Company income, gain, loss, expense or deduction for any fiscal period shall be allocated among the Members in such manner that, as of the end of such fiscal period and to the greatest extent possible, the Capital Account of each Member shall be equal to the respective net amount, positive or negative, which would be distributed to such Member from the Company or for which such Member would be liable to the Company under this Agreement, determined as if the Company were to (x) liquidate the assets of the Company for an amount equal to their book value (determined according to the rules of Treasury Regulation Section l.704-l(b)(2)(iv)) and (y) distribute the proceeds in liquidation in accordance with Section 13(b).

In the event that any property is contributed to the Company by a Member, gain or loss on the disposition of such property, and any losses or deductions with respect to such property, shall first be shared among the Members so as to take into account the variation between the basis of the property to the Company and its fair market value at the time of contribution, all in accordance with Code Section 704(c) and Treasury Regulations thereunder.

(i) Compensation of the Members. Members, as such, shall not receive any stated salary for their services, but shall receive such reimbursement by the Company for expenses incurred to attend regular or special meetings of the Members.

Expenses, including attorneys’ fees and expenses, incurred by any such Indemnified Person in defending a proceeding shall be paid by the Company in advance of the final disposition of such proceeding, including any appeal therefrom, upon receipt of an undertaking by or on behalf of such Indemnified Person (in form and substance acceptable to the Members) to repay such amount if it shall ultimately be determined that such Indemnified Person is not entitled to be indemnified by the Company.

(b) The right to indemnification and the advancement of expenses conferred in this Section 15 shall not be exclusive of any other right which any Person may have or hereafter acquire under any statute, agreement, vote of Members or otherwise.

(c) If this Section 15 or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Company shall nevertheless indemnify and hold harmless each Indemnified Person pursuant to this Section 15 to the fullest extent permitted by any applicable portion of this Section 15 that shall not have been invalidated and to the fullest extent permitted by applicable law. The indemnification provisions set forth in this Section 15 shall be deemed to be a contract between the Company and each of the Persons constituting Indemnified Persons at any time while the provisions of this Section 15 remain in effect, whether or not such Person continues to serve in such capacity and whether or not such Person is a party hereto. In addition, this Section 15 cannot be retroactively amended to adversely affect the rights of any Indemnified Persons arising in connection with any acts, omissions, facts or circumstances occurring prior to such amendment.
