1. The first paragraph under the heading “COMMUNICATING TO US ABOUT YOUR CONTRACT” is hereby deleted and replaced with the following:

All materials sent to us, including Purchase Payments, must be sent to our Annuity Mailing Address as set forth at the beginning of this Prospectus. For all telephone communications, you must call (800) 752-7215. We may accept certain communications or transaction requests from your authorized registered representative of the broker-dealer of record over the Internet on our broker website, but only after the registered representative has consented to our online terms of use.

2. The following is added under the heading “COMMUNICATING TO US ABOUT YOUR CONTRACT:

Electronic Account Information

You may elect to receive prospectuses, transaction confirmations, reports and other communications in electronic format, instead of receiving paper copies of these documents.  You may enroll in this optional electronic delivery service by visiting www.sunlife.com, selecting "Individuals" from the "Access your account" dropdown, and consenting to electronic delivery.  The electronic delivery service is subject to various terms and conditions, including a requirement that you promptly notify us of any change in your e-mail address, in order to avoid any disruption of deliveries to you. You may obtain more information and assistance at the above-mentioned internet location or by writing us at our Annuity Mailing Address or by telephone at (800) 752-7215.

3. The “Request for Transfers” section under the heading “Transfer Privilege” is hereby deleted and replaced with the following:

Requests for Transfers

You, your authorized registered representative of the broker-dealer of record, or another authorized third party may request transfers in writing or by telephone. Subject to availability and only after your authorized registered representative has consented to our online terms of use, we may also permit your authorized registered representative to request transfers electronically over the Internet on our broker website. If a written, telephone, or electronic transfer request is received before the earlier of (a) 4:00 p.m. Eastern Time on a Business Day, or (b) the close of the New York Stock Exchange on days that the Stock Exchange closes before 4:00 p.m., the transfer will be effective that day. The telephone transfer privilege is available automatically during regular business hours before 4:00 p.m. Eastern Time, and does not require your written election. We have established procedures reasonably designed to confirm that instructions communicated to us by telephone or electronically are genuine. These procedures may require any person requesting a transfer by telephone or electronically to provide personal identifying information. We will not be liable for following instructions communicated by telephone or electronically that we reasonably believe are genuine. We reserve the right to deny any and all transfer requests made by telephone or electronically and to require that certain transfer requests be submitted in writing. We also reserve the right to suspend, modify, restrict, or terminate the telephone or electronic transfer privilege at any time. Your ability (or the ability of your authorized registered representative or another authorized third party) to request transfers by telephone and/or electronically may be limited due to circumstances beyond our control, such as during system outages or periods of high volume.

A transfer request will be effective as of the close of the Business Day if we receive the transfer request, in good order, before the earlier of (a) 4:00 p.m. Eastern Time on a Business Day, or (b) the close of the New York Stock Exchange on days that the Stock Exchange closes before 4:00 p.m. Otherwise, the transfer request will be effective on the next Business Day.

Certain transfer requests may result in the modification or cancellation of one or more of the Contract’s optional programs or features that require, or are based on, specific allocations among the available Sub-Accounts or Guarantee Periods as described more particularly elsewhere in this Prospectus (and in the Appendices hereto).

No more than one transfer request of Account Values may be made on the same Business Day regardless of whether the request is made by you, your authorized registered representative, or another authorized third party, and regardless of whether the request is submitted in writing, by telephone, or electronically. The Company has established reasonable procedures for handling multiple transfer requests received on the same Business Day, including processing the first transfer request received in good order on a Business Day (unless otherwise cancelled in accordance with the cancellation procedures described below in the next paragraph).

You, your authorized registered representative, or another authorized third party may cancel a transfer request by contacting us by telephone at (800) 752-7215 before the end of the Business Day during which the transfer request was submitted.  Subject to availability, we may permit your authorized registered representative to request cancellation of a transfer request electronically over the Internet, provided we receive the electronic request before the end of the Business Day during which the transfer request was submitted.

4. The following is hereby added as the fourth paragraph under the heading “Reports to Owners.”

If you have enrolled in the electronic delivery service and consented to receive documents electronically, we will send you an email at the address you provided notifying you when we have posted your confirmations, statements, and reports on our website.

THIS SUPPLEMENT SHOULD BE READ AND RETAINED FOR FUTURE REFERENCE.
