Please furnish copies of the enclosed materials to those of your clients for whose accounts you hold Shares registered in your name or in the name of your nominee.

In order to take advantage of the Offer, (i) a duly executed and properly completed Letter of Transmittal and any required signature guarantees, or an Agent's Message (as defined in Section 2—"Acceptance for Payment and Payment for Shares" of the Offer to Purchase) in connection with a book-entry delivery of Shares, and other required documents should be sent to the Depositary and

Shareholders whose Share Certificates are not immediately available or who cannot deliver such certificates, or who cannot complete the procedure for delivery by book-entry transfer on a timely basis or who cannot deliver all other required documents to the Depositary prior to the expiration of the Offer (the "Expiration Date") may tender their Shares by properly completing and duly executing notice of guaranteed delivery enclosed with the Offer to Purchase (the "Notice of Guaranteed Delivery") pursuant to the guaranteed delivery procedure set forth in Section 3—"Procedures for Accepting the Offer and Tendering Shares"—of the Offer to Purchase.

Neither Parent nor the Offeror will pay any fees or commissions to any broker or dealer or to any other person (other than to the undersigned and the Depositary) in connection with the solicitation of tenders of Shares pursuant to the Offer. The Offeror will, however, upon request, reimburse you for customary mailing and handling costs incurred by you in forwarding the enclosed materials to your clients. The Offeror will pay or cause to be paid all stock transfer taxes applicable to its purchase of Shares pursuant to the Offer, except as otherwise provided in Instruction 6 of the Letter of Transmittal.

We urge you to contact your clients as promptly as possible. Please note that the Offer and withdrawal rights will expire at 5:00 p.m., Eastern time, on Wednesday, January 21, 2015, unless the Offer is extended or earlier terminated. Previously tendered Shares may be withdrawn at any time prior to the Expiration Date and, if Offeror has not accepted such Shares for payment by February 17, 2015, such Shares may be withdrawn at any time after that date until Offeror accepts Shares for payment.
