The section titled “Same-Sex Marriages” in your prospectus is deleted and replaced with the following:

Same-Sex Marriages
Before June 26, 2013, pursuant to Section 3 of the federal Defense of Marriage Act (“DOMA”), same-sex marriages
were not recognized for purposes of federal law. On that date the U.S. Supreme Court held in United States v.
Windsor that Section 3 of DOMA is unconstitutional. While valid same-sex marriages are now recognized under
federal law and the favorable income-deferral options afforded by federal tax law to an opposite-sex spouse under
Tax Code sections 72(s) and 401(a)(9) are now available to a same-sex spouse, there are still unanswered questions
regarding the scope and impact of the Windsor decision. Consequently, if you are married to a same-sex spouse you
should contact a qualified tax adviser regarding your spouse’s rights and benefits under the contract described in this
prospectus and your particular tax situation.
