(e)take any action that would have an adverse effect on the rights of Licensor in the Capstone Trademarks, or that would diminish or dilute the value, reputation or goodwill of the Capstone Trademarks or that would otherwise denigrate the image and reputation of Licensor or in any other way diminish or adversely affect the validity or enforceability of the Capstone Trademarks or Licensor’s rights therein; provided that,

(f)in the event that Licensee or any of its Affiliates (other than Licensor) nevertheless registers, files or prosecutes any application or other filing for any Trademarks incorporating or confusingly similar to a Capstone Trademarks, in Licensee’s (or its Affiliates’ (other than Licensor’s)) own name, Licensee hereby assigns, and shall cause its applicable Affiliates (other than Licensor) to assign, such Trademark to Licensor for no additional consideration.

Article III – QUALITY CONTROL

Section 3.1Quality Control. Licensee is familiar with and recognizes Licensor’s reputation as a provider of high quality products and services, and the reputation of Licensor’s offerings in connection with the Capstone Trademarks. Licensee shall maintain the same (or higher) standards of quality for its products and services. At Licensor’s request, Licensee shall promptly cease any use of the Capstone Trademarks that Licensor believes is not in compliance with this Agreement and take any corrective measures reasonably requested by Licensor. In the event that Licensor becomes aware of a failure to maintain or meet such quality standards, Licensor shall notify Licensee in writing and Licensee shall have thirty (30) days to cure such failure. If Licensee fails to meet the required quality standards to Licensor’s satisfaction within such period, Licensor may immediately suspend Licensee’s right to use the Capstone Trademarks in connection with the specific use that does not meet the quality standards, and if Licensee fails to meet the quality standards to Licensor’s satisfaction within the following sixty (60) day period, such failure shall be deemed a material breach for purposes of Section 5.2(b) of this Agreement.

Section 3.2Licensee’s Obligations of Compliance and Use.

(a)Licensee shall use and display the Capstone Trademarks in the same form, font, color and style as Licensor’s own use and display thereof, or in a manner substantially consistent with Licensor’s use and display during the twelve (12) month period prior to the Effective Date, or as otherwise approved by Licensor in writing in advance. Licensee shall not use or display the Capstone Trademarks in any manner that would reasonably be expected to (i) materially harm, degrade, disparage, tarnish, dilute or adversely affect the validity or enforceability of any Capstone Trademark, or (ii) imply that the Capstone Trademarks are owned by Licensee.

(b)All uses of the Capstone Trademarks by Licensee shall include the designation “®”, to the extent legally required or reasonably necessary for the enforcement of Trademark rights or as specifically directed otherwise by Licensor in writing. Licensor shall have the right to revise the above designation requirements upon written notice to Licensee from time to time.

(c)From time to time, at Licensor’s request and for the purpose of verifying compliance with this Article III of this Agreement, Licensee shall provide samples of Licensee’s use of public-facing materials bearing the Capstone Trademarks (including samples of advertising or marketing material), and any other further information reasonably requested by Licensor for that purpose.

Article IV – INTELLECTUAL PROPERTY PROTECTION

Section 4.1Notice of Infringement. Licensee shall promptly notify Licensor in writing of any infringement of the Capstone Trademarks by others which come to Licensee’s attention. Licensor shall have the sole right, but not the obligation, to determine what, if any, actions shall be taken on account of any such infringement, and, at Licensor’s sole cost and expense, Licensee shall reasonably cooperate in connection therewith.

Section 4.2Equitable Relief. Licensee acknowledges that the Capstone Trademarks and the goodwill associated therewith possess special, unique, and extraordinary characteristics, which make difficult the assessment of monetary damages which Licensor would sustain by Licensee’s unauthorized use. Licensee recognizes that Licensor would suffer irreparable injury by such unauthorized use and agrees that injunctive and other equitable relief is appropriate in the event of a breach of this Agreement by Licensee. Such remedy shall not be exclusive of any other remedies available to Licensor, nor shall it be deemed an election of remedies by Licensor.

Article V – TERM; TERMINATiON

Section 5.1Term. This Agreement shall commence on the Effective Date and shall continue in effect unless earlier terminated pursuant to Error! Reference source not found. (the “Term”).

Section 5.2Termination. This Agreement may be terminated solely (a) upon the written agreement of Licensor and Licensee, (b) by Licensor, if Licensee materially breaches this Agreement and does not cure such breach within thirty (30) days of receipt of notice from Licensor of such breach or (c) by Licensee, upon written notice to Licensor. If Licensor desires to assign any of its right, title and interest in and to the Capstone Trademarks to a third party that is not an Affiliate of Licensor, Licensor may do so solely with Licensee’s consent, not to be unreasonably withheld, delayed or conditioned (provided that, for the avoidance of doubt, Licensee’s withholding of consent for any assignment to a then competitor of Licensee would not be unreasonable). If Licensor does not use any of the Capstone Trademarks for a period of six (6) consecutive months, then all of Licensor’s right, title and interest in and to the Capstone Trademarks shall be promptly assigned to Licensee for no further consideration (provided that, for purposes of this Section 5.2, “use” of the Capstone Trademarks will mean conducting the Distributor Support Services business, using the name “Capstone”, including as a legal entity name, trade name, corporate name, “d/b/a” or business name (even if none of the Capstone Trademarks are used on any specific products or services), or using the name “Capstone” in any marketing related to such business).

Section 5.3Effect of Termination.

(a)Upon any expiration or termination of this Agreement, Licensee shall immediately cease all use of the Capstone Trademarks; provided that nothing in this Agreement shall prevent or restrict Licensee from making any use of the Capstone Trademarks that would constitute “fair use” or otherwise not be prohibited under Applicable Law if such use were made by a third party.

(b)Survival. Upon any expiration or termination of this Agreement, Error! Reference source not found., Error! Reference source not found., Error! Reference source not found., Article VII and Article VII shall survive and continue in full force and effect.

Article VI – indemnification

Section 6.1Indemnity. Licensee shall defend, indemnify and hold harmless Licensor, its Affiliates and each of its and their respective directors, officers, employees and agents (each, a “Licensor Indemnified Party”) from and against any and all losses, damages and liabilities (including attorneys’ fees) (“Losses”) to the extent resulting from or arising out of (a) any breach of this Agreement by Licensee or (b) use of the Capstone Trademarks (collectively, the “Licensed Rights”) by Licensee, except to the extent such Losses result from any claim of Trademark infringement arising from Licensee’s use of the Licensed Rights as authorized by this Agreement, provided that such use is in the same jurisdiction in which, and in connection with the same goods or services in connection with which, Licensor used such Licensed Rights prior to the Effective Date.

Section 6.2Indemnity Procedure. Licensor shall promptly provide Licensee with timely written notice of any and all claims that are within the scope of Licensee’s indemnity hereunder; provided that any failure to give such notice shall not affect the rights of Licensor under Section 6.1, except to the extent that such failure actually prejudices Licensee. Licensee shall not settle or compromise any claims against Licensor without Licensor’s prior written consent (which consent shall not be unreasonably withheld or delayed), unless such settlement or compromise: (i) includes an unconditional release of Licensor from all liability arising out of such claims; (ii) is solely monetary in nature; and (iii) does not include remedial or equitable measures or relief (including any injunction), a statement as to, or an admission of, fault, culpability or failure to act by or on behalf of, Licensor or otherwise materially adversely affect Licensor. Licensor shall furnish Licensee with such assistance as Licensee shall reasonably request in connection with the defense, settlement and/or discharge of any and all such claims.
