The Scotts Miracle-Gro Company, an Ohio corporation (the “Company”), is offering to exchange up to $400,000,000 in aggregate principal amount of its outstanding unregistered 6.000% Senior Notes due 2023 (the “Original Notes”) for an equal principal amount of registered 6.000% Senior Notes due 2023 (the “Exchange Notes”), upon the terms and subject to the conditions set forth in the prospectus dated             , 2017 (the “Prospectus”) and the accompanying Letter of Transmittal (the “Letter of Transmittal”). As described in the Prospectus, the terms of the Exchange Notes are substantially identical to the terms of the Original Notes, except that the Exchange Notes will not be subject to the transfer restrictions, registration rights and additional interest provisions applicable to the Original Notes. The Prospectus and the Letter of Transmittal, together, as the same may be amended, supplemented or otherwise modified from time to time, constitute the “Exchange Offer.”

We are requesting that you contact your clients for whom you hold Original Notes regarding the Exchange Offer. For your information and for forwarding to your clients for whom you hold Original Notes registered in your name or the name of your nominee, we are enclosing the following documents:

1. The Prospectus;

2. The Letter of Transmittal for your use in connection with the tender of Original Notes and for the information of your clients;

3. The Notice of Guaranteed Delivery to be used to accept the Exchange Offer if (i) certificates for Original Notes are not immediately available, (ii) the Letter of Transmittal, the Original Notes or any other required documents cannot be delivered to U.S. Bank National Association, the exchange agent for the exchange offer (the “Exchange Agent”), at or prior to the Expiration Time or (iii) the procedures for book-entry transfer cannot be completed at or prior to the Expiration Time; and

4. A form of letter that may be sent to your clients for whose account you hold Original Notes registered in your name or the name of your nominee, with space provided for obtaining such clients’ instructions with regard to the Exchange Offer.

We urge you to contact your clients as promptly as possible. Please note that the Exchange Offer will expire at 11:59 p.m., New York City time, on                 , 2017, unless extended. Original Notes validly tendered in the Exchange Offer may be withdrawn at any time prior to the Expiration Time.
