Pursuant to this Endorsement, UniGroup agrees to the following during the term of this Agreement:

     (a) Notifying Agents and Independent Owner-Operators. No later than fifteen (15) Business Days following the date hereof and at least once during each six (6)-month period thereafter, UniGroup agrees to inform the Van Lines Agents in writing that the Vanliner Companies are the Designated Exclusively-Endorsed Insurance Provider of

Vanliner Products with respect to the U.S. M&S Business. Additionally, with respect to new Van Lines Agents, UniGroup agrees to inform such Van Lines Agents in writing, as part of the standard information package provided to new Van Lines Agents, that the Vanliner Companies are the Designated Exclusively-Endorsed Insurance Provider of Vanliner Products with respect to the U.S. M&S Business.

     (b) Agents and Owner-Operators Seeking Insurance Information. UniGroup agrees that when a Van Lines Agent or an Independent Owner-Operator asks or otherwise seeks information on insurance placement for Vanliner Products from UniGroup, UniGroup will direct such Van Lines Agent or Independent Owner-Operator to contact Vanliner’s Designated Representative.

     (c) Participation in Events and Meetings. UniGroup agrees that the Vanliner Companies, at their own cost and discretion (which costs charged by UniGroup shall be determined in substantially the same manner as such costs have historically been determined by UniGroup for such participation, including by allowing historically consistent discounts to the amount of fees charged to the Vanliner Companies), shall be permitted to participate as the exclusive vendor of Vanliner Products in the following Van Lines Agents events (in each case, to the same extent the Vanliner Companies were historically permitted to participate, e.g., the Vanliner Companies will generally be permitted to participate in social events held during such events, but the Vanliner Companies will not be permitted to participate in any business or other shareholder sessions):

     (i) the Annual Convention;

     (ii) the Annual Learning Conference;

     (iii) the District Shareholder Meetings; and

     (iv) the Annual Shareholder Meeting.

UniGroup shall use its commercially reasonable efforts to notify the Vanliner Companies of such events in writing at least sixty (60) days in advance thereof or, if such sixty (60) day notice period is impracticable given the timing of the scheduling of any such event, with as much prior notice as is reasonably practicable, but in no event less than fourteen (14) days prior to the date of such event.

     (d) Posting Information on UniGroup Website. UniGroup agrees that, to the extent UniGroup maintains an internet website that may be accessed by Van Lines Agents, UniGroup will (i) include a hyperlink on its website to the Vanliner Companies’

     (e) Quarterly Reports. Subject to applicable Law and UniGroup’s applicable privacy policies (which privacy policies the parties acknowledge may be amended or otherwise changed by UniGroup at any time and from time to time in its sole discretion; provided that such amendments or changes are not made in bad faith for the purpose of prohibiting or restricting the performance by UniGroup of its obligations hereunder), UniGroup agrees that, within fifteen (15) Business Days following the closing of each calendar quarter, it will give Vanliner’s Designated Representative a written notice of the business name, contact name and updated contact information (e.g., mailing address, phone number and email address) for each then current Van Lines Agent and each then current Independent Owner-Operator; provided that, with regard to any such Independent Owner-Operators, the obligations of this Section 2(e) shall cease in the event that the Vanliner Companies cease to offer specialized insurance policies and insurance coverage to such Independent Owner-Operators.

     (f) Submissions for Publications. UniGroup shall allow the Vanliner Companies to purchase advertising space and submit articles to be considered for inclusion in newsletters, announcements and other publications that UniGroup sends or provides to the Van Lines Agents. Any advertising space or rights purchased by the Vanliner Companies shall be at rates determined in a manner substantially similar to the manner in which such rates historically have been determined by UniGroup (for the Vanliner Companies) for similar space, impressions and duration.
