Any purported or attempted assignment, sale or transfer of all or any part of a Holder’s Ownership Interest made in violation of this Agreement shall be null and void.

Section 2.2. No Separate Transfers of Company Ownership and Partnership Ownership Interests. The provisions of this Section 2.2 shall apply to all assignments, sales or other transfer of Ownership Interests, whether or not permitted under any other provision of this Agreement. It is the intent of the parties hereto that assignments, sales and other transfers of Company Ownership Interests and Partnership Ownership Interests be made only as a unit so that the ownership of the Company Ownership Interests and the Partnership Ownership Interests are held in the same relative proportions by the Holders or other owners thereof. Accordingly, no Holder may assign, sell or otherwise transfer all or any portion of a Company Ownership Interest or a Partnership Ownership Interest to any Person, including, without limitation, pursuant to an assignment, sale or other transfer permitted under other provisions of this Agreement, unless the Holder also simultaneously assigns, sells or transfers to the same Person the same relative portion of his respective Partnership Ownership Interest or Company Ownership Interest.

Section 2.3. Securities Laws Restrictions. Notwithstanding any other provision of this Agreement, no transfer of an Ownership Interest may be made if the transfer would violate any federal or state securities laws. The Company or the Partnership may require evidence satisfactory to it in its reasonable discretion of compliance with such laws.

Section 2.4. Continuation of Restrictions After Transfer. In the event of any permitted transfer of an Ownership Interest pursuant to this Agreement, the interest so transferred shall remain subject to all terms and provisions of this Agreement, including this Section 2.4, and the transferee shall be deemed, by accepting the interest so transferred, to have assumed all the liabilities and unperformed obligations, under this Agreement or otherwise, which are appurtenant to the interest so transferred; shall hold such interest subject to all unperformed obligations of the transferor Holder; and shall agree in writing to the foregoing if requested by the Company or any Holder.

III. PERMITTED TRANSFERS

Section 3.1. Permitted Affiliate Transfers. Notwithstanding Section 2.1 hereof, but subject to Sections 2.2 and 2.3 and Article V hereof, without the consent of the other Holders and without compliance with Articles IV or VI, any Holder may transfer any or all of its Ownership Interest to:

(i) any Affiliate of such Holder; or

(ii) any liquidating trust or other trust if a Person or Group of Persons who beneficially own all of the equity ownership interests in the Holder are collectively the beneficiaries of eighty percent (80%) or more of the assets of such trust.

A transfer permitted under this Section 3.1 is referred to herein as an “Affiliate Transfer”.

Section 3.2. Permitted Familial Transfers. Notwithstanding Section 2.1 hereof, but subject to Sections 2.2 and 2.3 and Article V hereof, without the consent of the other Holders and without compliance with Articles IV or VI, any Holder may transfer any or all of its Ownership Interest to:

(ii) any partnership, limited partnership, limited liability company, corporation or other entity or organization eighty percent (80%) or more of the equity ownership interests of which are beneficially owned, collectively, by one or more Family Member(s) of such Holder or of a Person who is the beneficial owner of a majority of the equity ownership interests of such Holder; or

(iii) any trust, if one or more Family Members of such Holder or of a Person who is the beneficial owner of a majority of the equity ownership interests in such Holder are collectively the beneficiaries of eighty percent (80%) or more of the assets of such trust.

The provisions of this Section 3.2 shall not be applicable to transfers that are also subject to Section 5.1(x) hereof. A transfer permitted under this Section 3.2 is referred to herein as a “Familial Transfer”.

Section 3.3. Pledges and Security Interests. Notwithstanding Section 2.1 hereof, but subject to Sections 2.2, 2.3 and Article V hereof, without the consent of the other Holders and without compliance with Articles IV and VI, any Holder may pledge or grant a security interest in its Ownership Interest to a bank or other lending institution to secure an obligation for borrowed money created in a bona fide financing transaction (a “Pledge”) provided that the pledgee or holder of the security interest shall agree in writing, for the benefit of the other Holders, (i) that the Ownership Interest that is the subject of such pledge or security interest is subject to this Agreement, (ii) to give each Member not less than sixty (60) days prior written notice of any proposed foreclosure, sale, taking or other disposition of any Ownership Interest pursuant to, as a result of or in connection with such Pledge, and (iii) that the rights of the Members under Article V hereof, including, without limitation, Sections 5.1(xii) and 5.11 thereof, shall apply to any such proposed foreclosure, sale, taking or other disposition and to the Ownership Interest subject to such Pledge.

IV. PERMITTED SALES SUBJECT TO RIGHT OF FIRST REFUSAL

Section 4.1. Sale of Ownership Interests. If the Selling Holder desires to effect a Sale, as hereinafter defined, of all or a part of its Ownership Interest to any Person other than pursuant to Sections 3.1 or 3.2 hereof, then, in addition to obtaining Holder Consent pursuant to Section 2.1, the Selling Holder shall comply with the provisions of this Article IV. For purposes of this Agreement, the term “Sale” shall mean any transfer for value of any Ownership Interests, directly or indirectly, including, without limitation, any such transfer pursuant to a transaction, or a series of related transactions, as a consequence of which any Ownership Interests are assigned or transferred to an Affiliate of the transferor of such Ownership Interests, which Affiliate simultaneously or subsequently engages in any business combination with a Person which is not an Affiliate of the original transferor of such Ownership Interest.

If the Electing Purchasers cannot agree upon the portion of the Offered Interest that each shall purchase, each Electing Purchaser may send a separate Acceptance Notice agreeing to purchase its Pro Rata Portion of the Offered Interest. In that case, each Electing Purchaser shall be entitled to purchase its Pro Rata Portion of the Company Ownership Interest and Partnership Ownership Interest comprising the Offered Interest.

Section 4.6. Closing of Sale. The closing of the sale of the Offered Interest to the Electing Purchasers shall take place at the principal place of business of the Company ten (10) days after the end of the Option Period (or, if such day is not a Business Day, the following Business Day), or at such other place and time as agreed to by the Selling Holder and the Electing Purchasers.

Section 4.7. Failure to Exercise Option. Subject to Section 2.5 hereof, if the right of first refusal option under this Article IV is not exercised within the Option Period as to all of the Offered Interest, or if the Electing Purchasers default on their obligation to purchase all of the Offered Interest, the Selling Holder may sell or transfer all but not less than all of the Offered Interest within ten (10) days thereafter to the prospective purchaser named in the RFR Notice at a price and on terms no more favorable to such purchaser than described in the RFR Notice, during which time such transfer shall be considered a permitted transfer hereunder and the prospective purchaser a permitted transferee hereunder.

Section 5.2. Notice of Sale. As soon as reasonably practicable following the occurrence of a Purchase Event, the Selling Holder shall give written notice (the “Purchase Event Notice”) of the Purchase Event to all Remaining Holders. If the Selling Holder shall fail or refuse to give the Purchase Event Notice, the Company may, but shall have no obligation to, give the Purchase Event Notice.

Section 5.3. Purchase Option. During the sixty (60) day period following receipt of the Purchase Event Notice, the Remaining Holders may elect to exercise their right to purchase the Selling Holder’s Ownership Interest (an “Offered Interest”) under this Section 5.3 (an “Option Period”). Then upon the expiration of the Option Period such right to purchase the Selling Holder’s Ownership Interest hereunder shall terminate, unless and until another Purchase Event shall occur with respect to the Selling Holder at which time the provisions of this Article V shall again be applicable to such Selling Holder’s Ownership Interest.

Section 5.4. Exercise of Purchase Option. The Remaining Holders shall give written notice to the Selling Holder prior to the expiration of the Option Period (an “Acceptance Notice”), if they desire to exercise their option to purchase the Offered Interest.

Section 5.5. Allocation of Interest Among Remaining Holders. The Acceptance Notice shall specify the portion of the Offered Interest that each Remaining Holders who elects to participate (an “Electing Purchaser”) in the purchase shall purchase. The Electing Purchasers, collectively, may not purchase less than all of the Offered Interest. If the Electing Purchasers cannot agree upon the portion of the Offered Interest that each shall purchase, each Electing Purchasers may send a separate Acceptance Notice agreeing to purchase its Pro Rata Portion of the Offered Interest. In that case, each Electing Purchaser shall be entitled to purchase its Pro Rata Portion of the Company Ownership Interest and Partnership Ownership Interest comprising the Offered Interest.

Section 5.6. Closing of Sale. The closing of the sale of the Offered Interest to the Electing Purchasers shall take place at the principal place of business of the Company thirty (30) days after the end of (i) the Option Period (or, if such day is not a Business Day, the following Business Day), or (ii) such longer period as may be required to complete the appraisal under Section 5.9, or at such other place and time as agreed to by the Selling Holder and the Electing Purchaser.

Section 5.7. Failure to Exercise Option. If the purchase option under this Article V is not exercised within the Option Period as to all of the Offered Interest, or if the Electing

Purchasers default on their obligation to purchase all of the Offered Interest, the Selling Holder shall not otherwise sell or transfer any of the Offered Interest to any Person without again complying with the terms of this Agreement.

Section 5.8. Purchase Price. The amount of the purchase price for the Selling Holder’s Ownership Interest (unless agreed upon by the Selling Holder and the Remaining Holders electing to participate in the purchase) shall be determined in accordance with Section 5.9 hereof.

Section 5.9. Procedure for Appraisal and Determination of Fair Market Value. Unless the Electing Purchasers and Selling Holder shall mutually agree upon the value for the Offered Interest, the value of the Offered Interest shall be determined by appraisal hereunder. The appraised value of the Offered Interest shall be determined within thirty (30) days after selection, by a single independent appraiser selected by agreement between the Electing Purchasers and Selling Holder (or its estate or representative) and such appraiser in turn may rely on other experts. If the Electing Purchasers and Selling Holder (or its estate or representative) cannot agree on a single independent appraiser within thirty (30) days after the delivery of the Acceptance Notice by the Electing Purchasers to the Selling Holder, then the Electing Purchasers, as a group, and the Selling Holder (or its estate or representative) shall each designate an independent appraiser, which appraisers shall meet within ten (10) days after their designation and proceed to determine the value of the Offered Interest within thirty (30) days of such initial meeting. If, during such thirty (30) day period, the two appraisers cannot reach agreement on the value of the Offered Interest, then, if the higher appraisal does not equal or exceed 105% of the lower appraisal, the arithmetic average of the appraisals designated by the appraisers shall be deemed to be the value of the Offered Interest; provided, however, that if the higher appraisal exceeds 105% of the lower appraisal, then the appraisers shall jointly appoint a third appraiser (the “Third Appraiser”) within ten (10) days after the expiration of such thirty (30) day period, whereupon the appraisal that is neither the highest nor the lowest of the three (3) appraisals shall be deemed to be the value of the Offered Interest and be binding and conclusive on the parties hereto. If any appraiser shall fail, refuse or become unable to act, a new appraiser shall be appointed in his place following the same method as was originally followed with respect to the appraiser to be replaced. If a single independent appraiser is selected by agreement between the Electing Purchasers, as a group, and the Selling Holder (or its estate or representative), the fees and expenses of such appraiser shall be borne equally by such parties; if the Electing Purchasers, as a group, and the Selling Holder (or its estate or representative) each designate appraisers, the fees and expenses of each such designated appraiser shall be borne by the party designating same; and if a Third Appraiser is designated, the fees and expenses of such Third Appraiser shall be borne equally by the Electing Purchasers and the Selling Holder (or its estate or representative). Any appraiser designated to serve in accordance with this Section 5.9 shall be independent of the party designating such appraiser. The determination of the value of the Offered Interest hereunder shall be conclusive on all parties. At any time during or following the determination of the value of the Offered Interest by any appraiser, the Electing Purchasers may elect to terminate their exercise of the option to purchase the Offered Interest, but in that case, the Electing Purchasers shall pay the fees and expenses of the appraiser selected by the Selling Holder and Third Appraiser, as well as its own appraiser.

Section 5.10. Effect on Seller’s Interest. Without limiting the generality of any other provision of this Agreement, upon the sale of the Offered Interest under this Article V, the

Selling Holder, without further action, will have no rights in the Partnership or the Company or against the Partnership or the Company or any Member or Partner other than the right to receive payment for the Offered Interest in accordance with this Article.

Section 5.11. Applicability to Transferees. The rights of the Remaining Holders under this Article V shall not be affected or diminished by any assignment, sale or transfer of an Ownership Interest effected in connection with any Purchase Event or any order purporting to effect or to require any such assignment, sale or transfer, and any such Ownership Interest shall remain subject to the provisions of this Agreement irrespective of any such assignment, sale or transfer, whether or not completed, and the assignee, purchaser or transferee shall take subject to the provisions of this Agreement and shall be bound thereby to the same extent as the Selling Holder.

VI. TAKE ALONG RIGHT

Section 6.1. Transactions Covered. In the event that one or more Holders who collectively hold a majority of the Ownership Interests (“Majority Seller”) propose to transfer all or any part of its or their Ownership Interests constituting majority of all the Ownership Interests in a single transaction or a series of related transactions to any Person other than pursuant to an Affiliate Transfer, a Familial Transfer or a Pledge, then such Holder or Holders shall first comply with this Article VI in addition to compliance with Article IV hereof.

Section 6.2. Notice. The Majority Seller shall give written notice (the “Take Along Notice”) to each Remaining Holder, contemporaneously with the RFR Notice under Section 4.2 and, to the extent not specified therein, identifying that portion of the Majority Seller’s Ownership Interest which it desires to transfer (the “Subject Interest”), the intended method of the transfer, the price the Majority Seller desires to receive for the Subject Interest, the proposed transfer date, and all other pertinent terms thereof, including, if known, the identity of any proposed buyer or buyers of the Subject Interest.

Section 6.3. Election to Participate. Any Remaining Holder may elect to participate in the contemplated transfer by delivering a written notice to the Majority Seller, within sixty (60) days (the “Take-Along Option Period”) after receipt of the Take Along Notice, specifying that portion of the Remaining Holder’s Ownership Interest (which may be all of such Ownership Interest) which such Remaining Holder elects to sell. Each such Remaining Holder who so elects (an “Electing Participant”) shall have the right to transfer in the contemplated transaction, at the same price and on the same terms, all or any portion of its Ownership Interest, except as limited in the following sentence. If the Electing Participants and the Majority Seller (singularly, a “Selling Party”, and collectively, the “Selling Parties”) in the aggregate elect to sell a larger portion of the Ownership Interest than the proposed buyer or buyers wish to purchase, then each Selling Party shall be entitled to sell to such buyer or buyers that percentage of its Ownership Interest which is equal to the percentage of the Ownership Interest to be so purchased by such buyer or buyers from all the Selling Parties multiplied by a fraction the numerator of which is the percentage of the Ownership Interest such Selling Party has specified in its notice under the first sentence of this Section that it elects to sell (without reference to the limitation imposed by this sentence) and the denominator of which is the aggregate percentage of the Ownership Interests
