Dear Juniper Stockholder,

Juniper Networks, Inc. has filed its annual proxy statement in anticipation of our 2013 annual meeting of stockholders on May 21, 2013. We know that proxy season is a very busy time and we are committed to ensuring that our proxy communications and related materials are transparent and reflect our accountability to our stockholders.

The purpose of this note is to thank you in advance for your continued support of Juniper and to bring your attention to an important proposal in this year’s proxy. The proposal seeks a non-binding advisory vote in favor of our executive compensation program. Known as a “say on pay” proposal, the vote is an opportunity for Juniper’s board and compensation committee to review stockholder feedback as it makes future executive compensation decisions.

The attached supplementary materials will provide you with more information with regard to our say on pay proposal. We recognize your support of Juniper is essential to our future growth. We hope we can count on your vote.
