(d) A Holder may convert a portion of a Security equal to $1,000 or any integral multiple thereof. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of a Security.
(e) If a Security is called for redemption pursuant to Section 3.01 of this Indenture, in order to convert such Security, the Holder must deliver the Security to the Conversion Agent (or, if the Security is held in book-entry form, complete and deliver to the Depositary appropriate instructions in accordance with the Applicable Procedures) at any time prior to the close of business on the Business Day immediately prior to the applicable Redemption Date for such Security (unless the Company shall default in paying the Redemption Price when due, in which case the conversion right shall terminate on the date such Event of Default is cured and such Security is redeemed). A Security in respect of which a Holder has delivered a Repurchase Notice pursuant to Section 3.02, or a Change in Control Repurchase Notice pursuant to Section 3.03 exercising the option of such Holder to require the Company to repurchase such Security, may be converted only if such Repurchase Notice or Change in Control Repurchase Notice, as the case may be, is withdrawn by a written notice of withdrawal delivered to the Paying Agent prior to the Repurchase Date or the Change in Control Repurchase Date, as the case may be, in accordance with Section 3.02 or Section 3.03, and Section 3.04, as applicable.
