2.2. Without an opinion of counsel satisfactory to the Managing Member that the Disposition is subject to an effective registration under, or exempt from the registration requirements of, any applicable state and federal securities laws; and

2.3. Unless and until the Company receives from the Assignee the information and agreements that the Managing Member may reasonably require, including but not limited to any taxpayer identification number and any agreement that may be required by any Taxing Jurisdiction.

ARTICLE XII

DISSOCIATION OF A MEMBER

1. Dissociation—A Person will cease to be a Member on the happening of any of the following events:

1.1. The resignation or withdrawal of a Member with the consent of a Majority of the remaining Members;

1.2. The bankruptcy of a Member;

1.3. In the case of a Member who is a natural person, the death of the Member or the entry of an order by a court of competent jurisdiction adjudicating the Member incompetent to manage the Member’s personal estate;

1.4. In the case of a Member who is acting as a Member by virtue of being a trustee of a trust, the termination of the trust (but not merely the substitution of a new trustee);

1.7. In the case of an estate, the distribution by the fiduciary of the estate’s entire interest in the limited liability company.

2. Rights of Dissociating Member—In the event any Member dissociates prior to the expiration of the Term:

2.1. If the dissociation causes a dissolution and winding up of the Company under Article XIV, the Member will be entitled to participate in the winding up of the Company to the same extent as any other Member except that any Distributions to which the Member would have been entitled will be reduced by the damages sustained by the Company as a result of the Dissolution and winding up;

2.2. If the dissociation does not cause a dissolution and winding up of the Company under Article XIV, the Member will be entitled to an amount equal to the capital account attributable to the Member’s interest in the Company, to be paid without interest over a period not to exceed five years. The dissociating member will be charged with, and his or her capital account (and, thus, the payments under this Paragraph 2.2) will be reduced by, the reasonable amount of any damages sustained by the Company as a direct result of the Member’s dissociation, such as the costs of alternative capital or financing, related professional fees, filing fees and direct administrative costs.

ARTICLE XIII

ADMISSION OF ASSIGNEES AND MEMBERS

1. Rights of Assignees—The Assignee of a Membership Interest has no right to participate in the management of the business and affairs of the Company or to become a Member.

2. Admission of Substitute Members—An Assignee of a Membership Interest will be admitted as a Substitute Member and admitted to all the rights of the Member who initially assigned the Membership Interest only with the unanimous consent of the Members. If so admitted, the Substitute Member has all the rights and powers and is subject to all the restrictions and liabilities

of the Member originally assigning the Membership Interest. The admission of a Substitute Member, without more, will not release the Member originally assigning the Membership Interest from any liability to Company that may have existed prior to the approval.

ARTICLE XIV

DISSOLUTION AND WINDING UP

1. Dissolution—The Company will be dissolved and its affairs wound up, upon the first to occur of the following events, which, unless a Majority of the Members agree to continue the business, will constitute Dissolution Events:

1.1. The expiration of the Term, unless the business of the Company is continued with the consent of a majority of the Members;

1.2. The unanimous written consent of all of the Members;

1.3. The Dissociation of any Member, unless the business of the Company is continued with the consent of a majority of the Members within 90 days after the Dissociation;

1.4. The entry of a decree of judicial dissolution under the Act.

2. Lack of Consent of Majority to Continue the Business—Upon the occurrence of a Dissolution Event, if the remaining Members do not agree to continue the business by the consent of a Majority within 90 days after the occurrence of the Dissolution Event, the Members who voted to continue the business have the option to purchase the assets of the business from the Company at their fair market value, as determined by the Company’s accountant at the time the valuation is made.

3. Effect of Dissolution—Upon dissolution, the Company will cease carrying on business as distinguished from the winding up of the Company business. The Company is not terminated, but continues until the winding up of the affairs of the Company is completed and the Certificate of Dissolution has been issued by the Secretary of State of Ohio.

4. Distribution of Assets on Dissolution—Upon the winding up of the Company, the Company Property will be distributed:

4.1. To creditors, including Members who are creditors, to the extent permitted by law, in satisfaction of Company Liabilities;

4.2. To Members in accordance with positive Capital Account balances taking into account all Capital Account adjustments for the Company’s taxable year in which the liquidation occurs. Liquidation proceeds will be paid within 60 days of the end of the Company’s taxable year or, if later, within 90 days after the liquidation. These distributions will be in cash or Property (which need not be distributed proportionately) or partly in both, as determined by the Managing Member.

5. Winding Up and Certificate of Dissolution—The winding up of the Company will be completed when all debts, liabilities, and obligations of the Company have been paid and discharged or reasonably adequate provision for them has been made, and all of the remaining property and assets of the Company have been distributed to the Members. Upon the completion of winding up

the Company, a certificate of dissolution will be delivered to the Secretary of State of Ohio for filing. The certificate of dissolution will set forth the information required by the Act.

ARTICLE XV

AMENDMENT

1. Operating Agreement May be Modified—The Operating Agreement may be modified as provided in this Article XV (as that Article is from time to time amended). No Member will have any vested rights in the Operating Agreement which may not be modified through an amendment to the Operating Agreement.

3. Rights of Creditors and Third Parties under Operating Agreement—The Operating Agreement is entered into among the Company and the Members for the exclusive benefit of the Company, its Members, and their successors and assignees. The Operating Agreement is expressly not intended for the benefit of any creditor of the Company or any other Person.
