Item 6.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Designation of Series A Preferred Stock

The Series A Preferred Stock issued at the closing of the Private Placement (the “Private Placement Closing”) has the powers, designations, preferences, and other rights set forth in the form of Certificate of Designations of the Series A Preferred Stock (the “Certificate of Designations”). The Holders (as defined below) are entitled to dividends on the original purchase price paid by the Purchaser at the rate of 4.5% per annum that (i) for the first three years after the Private Placement Closing will be paid in-kind, and (ii) after the third anniversary of the Private Placement Closing, will, at the Issuer’s election either be paid in cash, or, if not, will accrue and accumulate, in each case, accruing daily and paid quarterly in arrears. The Holders (as defined below) are also entitled to participate in dividends declared or paid on the Common Stock on an as-converted basis. The Series A Preferred Stock ranks senior to the Common Stock with respect to dividend rights and rights upon the voluntary or involuntary liquidation, dissolution, or winding up of the affairs of the Issuer (a “Liquidation”). Upon a Liquidation, each share of Series A Preferred Stock would be entitled to receive an amount per share equal to the greater of (i) the purchase price paid by the Purchaser, plus all accrued and unpaid dividends and (ii) the amount that the holder of Series A Preferred Stock (each, a “Holder” and collectively, the “Holders”) would have been entitled to receive at such time if the Series A Preferred Stock were converted into Common Stock (the “Liquidation Preference”).

Conversion Rights

The Holder has the right, at its option, to convert its Series A Preferred Stock, in whole or in part, into fully paid and non-assessable shares of Common Stock at a conversion price equal to $17.25 per share subject to certain customary adjustments in the event of certain adjustments to the Common Stock.

After the third anniversary of the Private Placement Closing, subject to certain conditions, the Issuer may, at its option, require conversion of all of the outstanding shares of Series A Preferred Stock to Common Stock if, for at least 20 trading days during the 30 consecutive trading days immediately preceding the date the Issuer notifies the Holders of the election to convert, the closing price of the Common Stock is at least 175% of the conversion price.

Redemption Rights

After the seventh anniversary of the Private Placement Closing, each Holder shall have the right to require the Issuer to redeem all or any part of the Holder’s Series A Preferred Stock for cash at a price equal to the original purchase price paid by the Purchaser plus any accrued and unpaid dividends. Upon a “Fundamental Change” (involving a change of control, bankruptcy, insolvency, liquidation or de-listing of the Issuer as further described in the Certificate of Designations), each Holder shall have the right to require the Issuer to redeem all or any part of the Holder’s Series A Preferred Stock for an amount equal to the Liquidation Preference at a repurchase price calculated in accordance with the Certificate of Designations plus any accrued and unpaid dividends.

Voting & Consent Rights

The Holders are generally entitled to vote with the holders of the shares of Common Stock on all matters submitted for a vote of holders of shares of Common Stock (voting together with the holders of shares of Common Stock as one class) on an as-converted basis, subject to certain Nasdaq voting limitations, if applicable.

Additionally, the consent of the Holders of a majority of the outstanding shares of Series A Preferred Stock is required for so long as any shares of the Series A Preferred Stock remain outstanding for (i) amendments to the Issuer’s organizational documents that have an adverse effect on the holders of Series A Preferred Stock and (ii) issuances by the Issuer of securities that are senior to, or equal in priority with, the Series A Preferred Stock. In addition, for so long as 25% of the Series A Preferred Stock issued in connection with the Financing Agreements remains outstanding, consent of the Holders of a majority of the outstanding shares of Series A Preferred Stock is required for (i) any change to the size of the Board, (ii) any voluntary dissolution, liquidation, bankruptcy, winding up or deregistration or delisting and (iii) incurrence by the Issuer of net debt in excess of $350,000,000.

Purchaser Governance Rights

For so long as the Purchasers hold 65% of the Series A Preferred Stock issued to them under the Financing Agreement, the Purchasers will have the right to nominate for election one member to the Board (the “Series A Director”), provided that the Purchasers’ initial nominee will be appointed to the Board at the Private Placement Closing as a Class I director and will not be entitled to any compensation from the Issuer for his service. The Purchasers have appointed Viral Patel as its initial nominee ot the Board.

Registration Rights Agreement

Holders of Series A Preferred Stock and Common Stock issuable upon conversion of Series A Preferred Stock issued to the Purchasers pursuant to the Financing Agreements will have certain customary registration rights with respect to such shares of Series A Preferred Stock and Common Stock issuable upon conversion of Series A Preferred Stock pursuant to the terms of the Registration Rights Agreement (the “Registration Rights Agreement”).
