| | |
|:---|:---|
| **Item 3.** | **Source or Amount of Funds or Other Consideration.** |

---

No funds were needed for the GRAT to acquire the shares common stock, as the shares were contributed to the GRAT by Dr. Vahaviolos as a gift for estate planning purposes. Dr. Vahaviolos owned the Shares contributed to the GRAT for over 13 years prior to the establishment of the GRAT. The shares of Common Stock owned by Ms. Foglia and members of her immediate family were not acquired in connection with the creation of the GRAT.

---

The transaction involves the contribution via gift by Dr. Vahaviolos of 6,734,718 shares of Common Stock to the GRAT for estate planning purposes.

The Reporting Persons have no present intention to make any dispositions of the shares of Common Stock in the GRAT, other than (i) to make annuity payments in the form of shares of Common Stock to Dr. Vahaviolos in

------

accordance with the terms of the GRAT, and (ii) upon the termination of the GRAT on or about the second anniversary date of its establishment, to make distributions in accordance with the terms of the GRAT of any shares of Common Stock remaining in the GRAT to the beneficiaries. Notwithstanding the foregoing, the Reporting Persons reserve the right to change their intention and may at any time, or from time to time, decide to dispose of all or a portion of the shares of Common Stock owned by the GRAT in the open market, in privately negotiated transactions or otherwise. The Reporting Persons have no present plans or proposals that relate to or that would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D. Ms. Foglia, as trustee, and Dr. Vahaviolos, as grantor, have agreed with the Issuer that the shares of Common Stock held by the GRAT will be subject to the Issuer's insider trading compliance policy.
