4. Denominations; Transfer; Exchange.
The Notes are in registered form, without coupons, in denominations of $2,000 and multiples of $1,000 thereafter. A Holder shall register the transfer or exchange of Notes in accordance with the Indenture. The Issuer may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Issuer need not issue, authenticate, register the transfer of or exchange any Notes or portions thereof for a period of fifteen (15) days before the mailing of a notice of redemption, nor need the Issuer register the transfer of or exchange any Note selected for redemption, in whole or in part.
5. Limitations on Liens.
The Issuer shall not issue, incur, create, assume or guarantee any Indebtedness secured by a Lien upon any Principal Property or upon any of the Capital Stock or Indebtedness of any of its Significant Subsidiaries (whether such Principal Property, or Capital Stock or Indebtedness is then existing or owed or is thereafter created or acquired) without in any such case effectively providing, concurrently with the issuance, incurrence, creation, assumption or guaranty of any such secured Indebtedness, or the grant of such Lien, that the Notes (together, if the Issuer shall so determine, with any other Indebtedness of or guarantee by the Issuer ranking equally with the Notes) shall be secured equally and ratably with (or, at the option of the Issuer, prior to) such secured Indebtedness, except:
(i) Liens existing on the Issue Date;
(ii) Liens on assets or property of a Person at the time it becomes a Subsidiary, securing Indebtedness of such Person, provided such Indebtedness was not incurred in connection with such Person or entity becoming a Subsidiary and such Liens do not extend to any assets other than those of the person becoming a Subsidiary;
(iii) Liens on property or assets of a Person existing at the time such person is merged into or consolidated with the Issuer or any of its Subsidiaries, or at the time of a sale, lease or other disposition of all or substantially all of the properties or assets of a person to the Issuer or any of its Subsidiaries, provided that such Lien was not incurred in anticipation of the merger, consolidation, or sale, lease, other disposition or other such transaction by which such Person was merged into or consolidated with the Issuer or any of its Subsidiaries;
(iv) Liens existing on assets created at the time of, or within the 12 months following, the acquisition, purchase, lease, improvement or development of such assets to secure all or a portion of the purchase price or lease for, or the costs of improvement or development of (in each case including related costs and expenses), such assets;
(v) Liens to secure any extension, renewal, refinancing or refunding (or successive extensions, renewals, refinancings or refundings), in whole or in part, of any Indebtedness secured by Liens referred to in this Section 5, so long as such Lien is limited to all or part of substantially the same property which secured the Lien extended, renewed or replaced, and the amount of Indebtedness secured is not increased (other than by the amount equal to any costs and expenses (including any premiums, fees or penalties) incurred in connection with any extension, renewal, refinancing or refunding);
