### CHARTER AMENDMENT PROPOSAL - INCREASE IN AUTHORIZED SHARES

#### Purpose of the Charter Amendment
We are asking you to adopt an amendment to the Company’s Second Amended and Restated Certificate of Incorporation, which is attached to this Proxy Statement as Appendix A, to increase the number of shares of our Common Stock authorized for issuance from 500,000,000 to 1,000,000,000. The Board believes it is in the best interest of the Company to increase the number of authorized shares of Common Stock to provide the Company with the flexibility to issue additional shares of Common Stock for a variety of corporate purposes without the delay and expense of seeking stockholder approval at a future special meeting. These purposes may include, but are not limited to:

• Facilitating strategic partnerships, joint ventures or other collaborative arrangements;

• Financing growth initiatives and capital expenditures through equity or equity-linked offerings;

• Providing equity incentives to employees, officers and directors pursuant to the Company’s compensation plans; and

• Other general corporate purposes approved by the Board.
