Litigation and Other Proceedings. (a) Unless Grantor determines in the exercise of its reasonable business judgment that (i) the Trademark at issue is of immaterial value and (ii) loss of the exclusive use of such Trademark would not have a material adverse effect on Grantor's condition (financial or otherwise) or on the collateral, Grantor shall have the obligation to commence and diligently prosecute such suits, proceedings or other actions for infringement or other damage, or reexamination or reissue proceedings, or opposition or cancellation proceedings as are reasonable to protect any of the Trademarks. No such suit, proceeding or other actions shall be settled or voluntarily dismissed, nor shall any party be released or excused of any claims of or liability for infringement, without the prior written consent of Lender, which consent shall not be - 5 - unreasonably withheld. (b) Upon the occurrence and during the continuation of an Event of Default, Lender shall have the right but not the obligation to bring suit or institute proceedings in the name of Grantor or Lender to enforce any rights in the Collateral, including any license thereunder, in which event Grantor shall at the request of Lender do any and all lawful acts and execute any and all documents required by Lender in aid of such enforcement. If Lender elects not to bring suit to enforce any right under the Collateral, including any license thereunder, Grantor agrees to use all reasonable measures, whether by suit, proceeding or other action, to prevent the infringement of any right under the Collateral by any Person and for that purpose agrees to diligently maintain any action, suit or proceeding against any Person so infringing necessary to prevent such infringement. 7. Default and Remedies. (a) Grantor shall be deemed in default under this Security Agreement upon the occurrence of an Event of Default. Upon the occurrence and during the continuation of any such Event of Default, Lender may, at its option, and (except if otherwise specified below) without notice to or demand on Grantor, and in addition to all rights and remedies available to Lender under the Guaranty or the other loan documents, do any one or more of the following: (i) upon ten (10) days' prior notice to Grantor, direct Grantor not to make any further use of the Trademarks (or any mark similar thereto) for any purpose; (ii) at any time and from time to time, upon ten (10) days' prior notice to Grantor, license, whether general, special or otherwise, and whether on an exclusive or nonexclusive basis, any of the Trademarks throughout the world for such term or terms, on such conditions, and in such manner, as Lender shall in its sole discretion determine; (iii) at any time and from time to time, enforce (and upon notice to Grantor have the exclusive right to enforce) against any licensee or sublicensee all rights and remedies of Grantor in, to and under any one or more license agreements with respect to the Collateral (without assuming any obligations or liability thereunder), and take or refrain from taking any action under any thereof; (iv) at any time and from time to time, upon ten (10) days' prior - 6 - notice to Grantor, assign, sell, or otherwise dispose of, the Collateral or any of it, either with or without special or other conditions or stipulations, with power to buy the Collateral or any part of it, and with power also to execute assurances, and do all other acts and things for completing the assignment, sale or disposition which Lender shall, in its sole discretion, deem appropriate or proper; and (v) in addition to the foregoing, in order to implement the assignment, sale or other disposal of any of the Collateral pursuant to clause (a)(iv) hereof, Lender may, at any time, pursuant to the authority granted in the Power of Attorney executed pursuant to Subparagraph 5(b) hereof, execute and deliver on behalf of Grantor, one or more instruments of assignment of the Trademarks (or any application for registration thereof), in form suitable for filing, recording or registration in any country. (b) Grantor agrees to pay when due all reasonable costs incurred in any such transfer of the Trademarks, including, without limitation, any taxes, fees and reasonable attorneys' fees and expenses, and all such costs shall be added to the Obligations. Lender may apply the proceeds actually received from any such license, assignment, sale or other disposition to the reasonable costs and expenses thereof, including, without limitation, reasonable attorneys' fees and all legal, travel and other expenses which may be incurred by Lender, and then to the Obligations, in such order as to principal or interest as Lender may desire; and Grantor shall remain liable and will pay Lender on demand any deficiency remaining, together with interest thereon at a rate equal to the highest rate then payable on the Obligations and the balance of any expenses unpaid. Nothing herein contained shall be construed as requiring Lender to take any such action at any time. In the event of any such license, assignment, sale or other disposition of the Collateral, or any of it, after the occurrence or continuation as hereinabove provided of an Event of Default, Grantor shall supply its know-how and expertise relating to the manufacture and sale of the products bearing the Trademarks or in connection with which the Trademarks are used, and its consumer or customer lists and other records relating to the Trademarks and to the distribution of products or the provisions of services, to Lender or its designee. - 7 - (c) In furtherance of Lender's rights hereunder, Grantor hereby grants to Lender an irrevocable, non-exclusive license (exercisable without royalty or other payment by Lender) to use, license or sublicense any Trademark in which Grantor now or hereafter has any right, title or interest together with the right of access to all media in which any Trademark may be recorded or stored. Such license shall be exercisable only upon the occurrence and during the continuation of an Event of Default (after any applicable cure periods have expired). 8. Reassignment. Upon the payment in full of the Obligations and the termination of the Guaranty and Lender's obligation to provide advances thereunder, Lender shall execute and deliver to Grantor (at no expense to Lender) all assignments and other instruments as may be necessary to vest in Grantor full right, title and interest in and to the Collateral, subject to any disposition thereof which may have been made by Lender pursuant to the provisions of this Security Agreement. 9. Indemnification and Release. (a) Grantor assumes all responsibility and liability arising from the use of the Trademarks, and Grantor shall indemnify and hold Lender and its directors, officers, employees, agents and any of their respective Affiliates ("Indemnitees") harmless from and against any claim, suit, loss, damage or expense (including, without limitation, reasonable attorneys' fees and expenses) arising out of or in connection with any alleged infringement of any trademark or alleged defect in any product manufactured, promoted or sold by Grantor (or any Affiliate of Grantor) in connection with any Trademark, or out of the manufacture, promotion, labeling, sale or advertisement of any product or service by Grantor (or any Affiliate of Grantor). Grantor agrees that Lender does not assume, and shall have no responsibility for, the payment of any sums due or to become due under any agreement or contract included in the Collateral or the performance of any obligations to be performed under or with respect to any such agreement or contract by Grantor, and Grantor hereby agrees to indemnify and hold each Indemnitee harmless with respect to any and all claims by any Person relating thereto. (b) Grantor agrees to indemnify and hold each Indemnitee harmless from and against any claim, suit, loss, damage or expense (including, without limitation, reasonable attorneys' fees and expenses) arising out of or in connection with any action taken or omitted to be taken by Lender pursuant to clause 7(a)(iii) hereof with respect to any license agreement of Grantor.
