Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Designation of Series B Preferred Stock

The Series B Preferred Stock issued to the Reporting Persons at the closing of the Private Placement (the “Private Placement Closing”) has the powers, designations, preferences, and other rights set forth in the Certificate of Designation of the Series B Preferred Stock (the “Certificate of Designation”). The holders of Series B Preferred Stock (each, a “Holder” and collectively, the “Holders”) are entitled to dividends on the initial liquidation preference

24

of the Series B Preferred Stock at the rate of 5.5% per annum, payable in cash or in certain circumstances, in kind using the Issuer’s Common Stock. The Holders are also entitled to participate in dividends declared or paid on the Common Stock on an as-converted basis. The Series B Preferred Stock ranks senior to the Common Stock and the Issuer’s Series A Preferred Stock, par value $0.0001 per share (the “Series A Preferred 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 B Preferred Stock will be entitled to receive the greater of (i) an amount per share equal to the initial liquidation preference of the Series B Preferred Stock, plus all accrued and unpaid dividends, and (ii) the amount the Series B Preferred Stock would be entitled to receive on an as-converted to Common Stock basis (the “Liquidation Preference”).

Conversion Rights

Each Holder will have the right, at its option, to convert its Series B Preferred Stock, in whole or in part, into fully paid and non-assessable shares of Common Stock at a conversion price equal to $24.60 per share subject to certain customary adjustments in the event of certain events affecting the price of the Common Stock (the “Conversion Price”).

Subject to certain conditions, the Issuer may, at its option, require conversion of all, but not less than all, of the outstanding shares of Series B Preferred Stock to Common Stock if the average share volume-weighted average price of the Common Stock for 15 consecutive trading days exceeds 150% of the Conversion Price.

Redemption Rights

The Issuer may redeem all or any of the Series B Preferred Stock for cash at any time beginning five years after the Private Placement Closing at a price equal to 105% of the purchase price paid by the Purchasers plus any accrued and unpaid dividends. Upon a “Fundamental Change” (involving a change of control or de-listing of the Issuer as further described in the Certificate of Designation), each Holder shall have the right to require the Issuer to redeem all or any part of the Holder’s Series B Preferred Stock for an amount equal to the Liquidation Preference (including any accrued and unpaid dividends and a customary make-whole amount).

Voting & Consent Rights

The Holders generally will be 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.

Additionally, the consent of the Holders of a majority of the outstanding shares of Series B Preferred Stock will be required for so long as any shares of the Series B Preferred Stock remain outstanding for, among other things, (i) amendments to the Certificate of Designation or the Issuer’s Certificate of Incorporation that would alter or change the powers or preferences of the Series B Preferred Stock, (ii) any increase or decrease of the authorized number of shares of Series B Preferred Stock, (iii) any issuance of shares of Series B Preferred Stock, (iv) the creation of securities that are senior to, or equal in priority with, the Series B Preferred Stock, (v) any amendments to the Issuer’s organizational documents that have an adverse effect on the Holders, (vi) any action to deregister or delist the Common Stock, or (vii) the entering into a transaction with an affiliate of the Issuer other than on terms no less favorable to the Issuer than would be obtained in an arms’ length transaction with a bona fide third party, as determined by the Board in its reasonable judgment. In addition, any action that would adversely affect the rights of any Holder of Series B Preferred Stock in a manner disproportionate to the other Holders of Series B Preferred Stock will require the consent of such affected Holder.

Preemptive Rights

So long as the Purchasers collectively own, of record or beneficially, at least 50% of the Series B Preferred Stock issued to them under the Financing Agreement, at any time the Issuer makes any non-public offering of any capital stock or securities convertible into capital stock (subject certain customary exceptions), the Purchasers shall have the right to acquire from the Issuer its pro rata portion of the stock being offered.

25

Registration Rights Agreement

On January 3, 2022, the Purchasers and the Issuer entered into a Registration Rights Agreement (the “Registration Rights Agreement”). Pursuant to the terms of the Registration Rights Agreement, Holders of Series B Preferred Stock and Common Stock issuable upon conversion of, or payments of dividends on, Series B Preferred Stock pursuant to the Financing Agreement will have certain customary registration rights with respect to such shares of Series B Preferred Stock and Common Stock.

Purchaser Governance Rights

For so long as the Purchasers collectively own, of record or beneficially, at least 50% of the Series B Preferred Stock (or shares of Common Stock issued upon conversion thereof) issued to them under the Financing Agreement, the Purchasers will have the right to nominate for election one member (the “Series B Director”) to the Board. The Purchasers’ initial nominee to serve as Series B Director was David Blitzer, and Mr. Blitzer was elected to the Board following the issuance of the Series B Preferred Stock on January 3, 2022.

Purchaser Standstill

Additionally, for so long as the Purchasers have the right to nominate the Series B Director, the Purchasers will be subject to certain standstill restrictions pursuant to which the Purchasers will be restricted, among other things and subject to certain customary exceptions, from (i) acquiring additional equity securities or securities exchangeable for or convertible into equity securities of the Issuer; (ii) seeking representation on the Board (beyond their right to elect the Series B Director); (iii) seeking to change or influence the policies or management of the Issuer (beyond their right to elect the Series B Director); (iv) submitting any stockholder proposal to the Issuer; (v) publicly proposing any change of control or other material transaction involving the Issuer; or (vi) supporting or encouraging any person in doing any of the foregoing.

Margin Loan Facility

Juno Lower Holdings and FD Juno Holdings, as co-borrowers (the “Borrowers”), entered into a Margin Loan Agreement (the “Loan Agreement” and, together with each agreement or instrument delivered pursuant to the foregoing or pursuant to the security interests and collateral granted in accordance with the foregoing, the “Loan Documents”), dated as of December 31, 2021, with the lenders from time to time party thereto (the “Lenders”) and Royal Bank of Canada, as administrative agent, pursuant to which the Borrowers agreed to pledge, effective as of January 3, 2022, (x) an aggregate of 600,000 shares of Series B Preferred Stock, and (y) any shares of Common Stock issued upon conversion of such Series B Preferred Stock or issued as a dividend thereon, as collateral to secure their obligations under the Loan Agreement. The Borrowers borrowed an aggregate of $225 million under the Loan Agreement on January 3, 2022.

The loan matures on or about January 3, 2025. Upon the occurrence of certain events that are customary for this type of loan, the Lenders may exercise their rights to require the Borrowers to pre-pay the loan proceeds or post additional collateral, or foreclose on, and dispose of, the pledged Series B Preferred Stock and/or the pledged Common Stock, as applicable, in accordance with the Loan Documents.

The description of the Financing Agreement, Certificate of Designation, Registration Rights Agreement and Loan Agreement contained in this Item 6 are not intended to be complete and are qualified in their entirety by reference to such documents. The Financing Agreement, Registration Rights Agreement and Loan Agreement are filed as exhibits hereto and incorporated by reference herein.
