10.           Transfer of a Member’s Interest.  This Section 10 shall apply if and when there are two or more Members of the Company.

10.1.        Voluntary Transfer.

10.1.1.        A Member may voluntarily assign or transfer that Member’s interest in the Company to another person, provided that Member first receives a bona fide offer to purchase from a third party and then gives to all of the other Members the right to purchase the interest to be assigned or transferred.  The remaining Members shall be entitled to purchase that interest only if one or more of these remaining Members elect to purchase all of that interest in accordance with the procedure set forth in this Section 10.1.1.  The purchase price to the

7

remaining Members for that interest shall equal the price offered by the proposed assignee or transferee (expressed in U.S. currency, as commonly available).  The other terms for that purchase shall be the same as the terms offered by the proposed assignee or transferee.  The remaining Members shall have the right to accept the offer to purchase that interest at any time within sixty (60) days after receiving notice from the assigning or transferring Member that the interest is available for purchase.  Each purchasing Member shall be entitled to purchase its pro rata share of that interest, or such lesser share as it shall elect.  The pro rata shares shall be based on the relative percentage interests of the purchasing Members in the profits of the Company.  If any portion of that interest is unsubscribed because one or more of the purchasing Members does not elect to purchase its pro rata share of the interest, the unsubscribed portion may be purchased by the remaining purchasing Members, with each such Member being entitled to purchase its pro rata share.

10.1.2.        If the remaining Members purchase the interest under Section 10.1.1, their respective interests in the Company shall be increased by their respective shares of the interest purchased.  The Members and the Managers shall execute such consents as shall be necessary to accomplish the provisions of the preceding sentence.  If the remaining Members shall fail to accept the offer within the 60-day period, such interest may during the following 60 days be disposed of; provided, however, that the purchase price for such interest shall not be less and the terms of purchase for such interest shall not be more favorable than the purchase price and terms of purchase that would have been applicable to the remaining Members had the remaining Members purchased the interest.  Any interest not so disposed of within the 60-day period shall thereafter remain subject to the terms of this Operating Agreement.  If the remaining Members do not purchase the interest and the interest is transferred or assigned to a third party, that third-party assignee or transferee shall become a substitute Member having all the attributes of a Member if the conditions of Section 10.3 are satisfied.

10.1.3.        If a Member voluntarily assigns or transfers its interest to another person without giving the remaining Members the right to purchase the interest as provided in Section 10.1.1 or if the conditions of Section 10.3 are not satisfied as provided in Section 10.1.2, the third-party assignee or transferee shall not become a substitute Member but shall be deemed a transferee for whom consent was not given under Section 10.2.

10.2.        Involuntary Transfer.  No Member’s interest in the Company may be assigned or transferred involuntarily unless remaining Members entitled to receive a majority of the nontransferred profits of the Company consent to the assignment or transfer and the conditions of Section 10.3 are satisfied.  If such consent is not given or if the conditions of Section 10.3 are not satisfied:

10.2.1.        the transferee of the Member’s interest has no right to (i) vote or participate in the management of the business and affairs of the Company or (ii) become a Member;

10.2.2.        the transferee is entitled to receive only the share of profits or other compensation by way of income and the return of contributions to which that transferor Member would otherwise be entitled; and

8

10.2.3.        the consent, approval or agreement of the transferor Member or the transferee shall not be required or considered for any action by the Company or the Members.

For purposes of this Agreement, an involuntary transfer includes without limitation any transfer arising as the result of the death, divorce or bankruptcy of a Member or the attachment of a Member’s interest by a creditor.

10.3.        Substitute Member.  An assignee or transferee who is eligible to be a substitute Member under Sections 10.1 or 10.2 (the “Transferee”) shall be admitted as a substitute Member having all of the rights and powers of a Member if the following conditions are met:

10.3.1.        the Transferee shall deliver to the Managers documentation reasonably satisfactory to the Managers showing that the Transferee is entitled to the interest of the Member that was transferred;

10.3.2.        the Transferee shall execute and deliver to the Managers a written agreement, in form reasonably satisfactory to the Managers, pursuant to which the Transferee agrees to be bound by this Agreement; and

10.3.3.        the costs incurred by the Company associated with the admission of the substitute Member (including reasonable attorneys’ fees) shall be paid in advance by the Transferee.

10.4.        Effective Date of Transfer to Substitute Member.  In the event a transfer to a substitute Member is made in accordance with the foregoing terms of this Section 10, unless otherwise required by the Act or the Internal Revenue Code of 1986:

10.4.1.        the effective date of such transfer shall be the date the conditions described in Section 10.3 are satisfied; and

10.4.2.        the Company shall incur no liability for distributions or allocations made in good faith to a predecessor-in-interest of that substitute Member until such time as the conditions described in Section 10.3 are satisfied.

10.5.        Effective Date of Other Transfer.  In the event a transfer is made to a person who does not qualify as a substitute Member as provided in this Section 10, the Company shall incur no liability for distributions or allocations made in good faith to a predecessor-in-interest of that person until such time as the Managers shall have received written documentation which, in their sole discretion, verifies that the interest has been so transferred to that person.

11.           Dissolution.

11.1.        Events of Dissolution.  The Company shall be dissolved upon the occurrence of any of the following events:

11.3.        Articles of Dissolution.  When all debts, liabilities and obligations of the Company have been paid or discharged, or adequate provision has been made to do so, and all of the remaining property and assets of the Company have been distributed to the Members, articles of dissolution shall be executed and duly filed with the State of Utah.
