RECONVEYANCE Upon payment in full of all Secured Obligations, the Agent shall transfer to the Company and Pledgor at the Company's and Pledgor's expense, and the Company and Pledgor shall accept the transfer of, all Pledged Securities then held by or to the order of the Agent and the Agent shall co-operate in procuring the registration of such Pledged Securities in the name of the Company and Pledgor or as it shall direct. 11. PROTECTION OF SECURITY (1) The security created by this Deed shall be a continuing security notwithstanding any settlement of account or other matter or thing whatsoever, and in particular (but without prejudice to the generality of the foregoing) shall not be considered satisfied by an intermediate repayment or satisfaction of part only of the Secured Obligations and shall continue in full force and effect until total and irrevocable satisfaction of all the Secured Obligation. (2) The security created by this Deed shall be in addition to and shall not in any way prejudice or be prejudiced by any collateral or other security, right or remedy which the Agent may now or at any time hereafter hold for all or any part of the Secured Obligations. (3) No failure on the part of the Agent or any Lender to exercise and no delay on its part in exercising any right, remedy, power or privilege under or pursuant to this Deed or any other document relating to or securing all or any part of the Secured Obligations will operate -8- as a waiver thereof, nor will any single or partial exercise of any right or remedy preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies provided in this Deed and any such other document are cumulative and not exclusive of any right or remedies provided by law. (4) Each of the provisions in this Deed shall be severable and distinct from one another and if at any time any one or more of such provisions is or becomes or is declared null and void, invalid, illegal or unenforceable in any respect under any law or otherwise howsoever the validity, legality and unenforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby. (5) If any of the Agent, the Lender, the Note Trustee or the Note Holders receives or is deemed to be affected by notice whether actual or constructive of any subsequent security or other interest affecting any part of the Pledged Securities and/or the proceeds or sale thereof, any of the Agent, the Lender, the Note Trustee or the Note Holders may open a new account or accounts with the Company and Pledgor. If the Agent or such Lenders does not open a new account it shall nevertheless be treated as if it had done so at the time when it received or was deemed to have received notice and as from that time all payments made to the Agent or such Lender, the Note Trustee or the Note Holder shall be credited or be treated as having been credited to the new account and shall not operate to reduce the amount for which this Deed is security. (6) Neither the security created by this Deed nor the rights, powers, discretions and remedies conferred upon the Agent by this Deed or by law shall be discharged, impaired or otherwise affected by reason of: (a) any present or future security, guarantee, indemnity or other right or remedy held by or available to any of Agent, the Lenders, the Note Trustee or the Note Holders being or becoming wholly or in part void, voidable or unenforceable on any ground whatsoever or by any of Agent, the Lenders, the Note Trustee or the Note Holders from time to time exchanging, varying, realizing, releasing or failing to perfect or enforce any of the same; or (b) the Agent or any Lender or the Note Trustee or any Note Holder compounding with, discharging or releasing or varying the liability of, or granting -9- any time, indulgence or concession to, the Company and Pledgor or any other person or renewing, determining, varying or increasing any accommodation or transaction in any manner whatsoever or concurring in accepting or varying any compromise, arrangement or settlement or omitting to claim or enforce payment from the Company and Pledgor or any other person; or (c) any act or omission which would not have discharged or affected the liability of the Company and Pledgor had it been a principal debtor instead of cautioner or by anything done or omitted which but for this provision might operate to exonerate the Company and Pledgor from the Secured Obligations; or (d) any legal limitation, disability, incapacity or other similar circumstance relating to the Company and Pledgor. (7) The Agent shall not be obliged, before exercising any of the rights, powers or remedies conferred upon it by or pursuant to this Deed or by law, to: (a) take any action or obtain judgment or decree in any Court against the Company and Pledgor; (b) make or file any claims to rank in a winding-up or liquidation of the Company and Pledgor; or (c) enforce or seek to enforce any other security taken, or exercise any right or plea available to the Agent, in respect of any of the Company's and Pledgor's obligations under any document other than this Deed. 12.
