 and last name will receive only one copy of our proxy materials until such time as one or more of these stockholders notifies us that they want to receive separate copies. This procedure reduces duplicate mailings and saves printing costs and postage fees, as well as natural resources. Stockholders who participate in householding will continue to have access to and utilize separate proxy voting instructions.

If you receive a single set of proxy materials as a result of householding, and you would like to have separate copies of our proxy materials mailed to you, please submit a request to our Secretary at our principal executive offices, or contact Morrow Sodali, our proxy solicitor, at (800) 662-5200 or by emailing QTI@investor.sodali.com, and we will promptly send you what you have requested. You can also contact Morrow Sodali at the phone number above if you received multiple copies of the proxy materials and would prefer to receive a single copy in the future, or if you would like to opt out of householding for future mailings.
