7. Registration of Collateral. At any time after the occurrence and during the continuance of an Event of Default, Termination Event or Additional Termination Event (any such event hereinafter an “Event of Default”), Secured Party, at its option, may have the Collateral registered in its name or that of its nominee, and upon Secured Party’s request, Highland will cause the issuer of the Collateral or, if appropriate, the Securities Intermediary to effect such registration. At such time as all Events of Default have been cured or waived, the right to exercise all voting rights with respect to the Collateral shall revert to Highland.

9. Provision with Respect to Certain Damages. Notwithstanding any provision of the Agreement or of this Security Agreement to the contrary, in the event that the Party A Final Payment or the Early Termination Settlement Amount (as the case may be) is zero, then Highland shall be deemed to be in breach of the Agreement, Secured Party shall be deemed to have incurred damages of not less than the absolute value of the difference between the Notional Amount and the Reference Portfolio Value and Secured Party shall be entitled to apply the Collateral against such damages. The parties agree that in these circumstances such amount constitutes a reasonable pre-estimate of the Secured Party’s loss and not a penalty.

10. Legal Restrictions. Highland agrees that there may be legal or practical restrictions or limitations affecting Secured Party in any attempts to dispose of certain portions of the Collateral and for enforcement of its rights. Upon the occurrence of an Event of Default, if Secured Party elects to sell any of the Collateral at public or private sale, it may sell the Collateral at such sale subject to investment letter or in any other manner which will not require the Collateral, or any part thereof, to be registered in accordance with any laws or regulations, including but not limited to the Securities Act of 1933, as amended, or the rules and regulations promulgated thereunder, or make it necessary to obtain any required approval of the purchase or the purchaser by any governmental agency or officer, at the best price reasonably obtainable by Secured Party at such sale or other disposition in the manner mentioned above. Highland agrees that Secured Party may in its discretion approach a limited number of potential purchasers and that a sale under such circumstances may yield a lower price for the Collateral, or any part or parts thereof, than would otherwise be obtainable if same were either offered to a larger number of potential purchasers, or registered and sold in the open market. At any sale, (a) Secured Party may rely upon the advice and opinion of any member firm of a national securities exchange as to the best price reasonably obtainable upon such private sale thereof, and such reliance shall be conclusive evidence that Secured Party handled such matter in a commercially reasonable manner under applicable law; (b) Secured Party has no obligation to delay sale of any Collateral to permit the issuer thereof to register it for public sale under any applicable federal or state securities laws; and (c) such a sale shall be deemed to have been made in a commercially reasonable manner.

11. Attorney-in-Fact. Highland appoints Secured Party, its successors and assigns, as Highland’s attorney-in-fact (without requiring it to act as such), with full power of substitution, to do any act which Highland is obligated by this Security Agreement to do, including, but not limited to, the power to do the following upon the occurrence and during the continuance of an Event of Default: (a) become the entitlement holder, sell, dispose of, or issue entitlement orders with respect to the Collateral as herein provided, issue such orders and instructions as are necessary or appropriate to effect the registration of the Collateral on the books of the issuer of the Collateral or of any Securities Intermediary in the name of Secured Party or to effect the sale or disposition of the Collateral; (b) endorse the name of Highland on all checks, drafts, money orders, or other instruments for the payment of monies that are payable to Highland and constitute collections of the Collateral; (c) execute in the name of Highland any schedules, assignments, instruments, documents, financing statements, amendments of financing statements, applications for registration, and other papers deemed necessary or appropriate by Secured Party to perfect, preserve, or enforce the Security Interest; (d) exercise all rights of Highland in the Collateral; (e) make extension agreements with respect to Collateral; (f) make withdrawals from and close deposit accounts and other accounts with any financial institution into which proceeds may have been deposited and apply funds so withdrawn as provided herein; (g) give notice of Secured Party’s rights under this Security Agreement; (h) enter onto Highland’s premises to inspect the Collateral; and (h) do all acts and things and execute all documents in the name of Highland or otherwise, as reasonably necessary, in connection with the preservation, perfection, and enforcement of its rights hereunder.
