regarding the proposals made by JetBlue (which are described in detail under &#147;Background of the Solicitation&#148; below) despite the terms of the Frontier Merger Agreement which permit Spirit to engage in such discussions if the Spirit Board
concludes that the transaction with JetBlue could reasonably be expected to result in a superior proposal. As described above, our Offer is clearly financially superior. The Spirit Board nevertheless has refused to meaningfully engage in discussions
with JetBlue because it claims, without merit, that a JetBlue-Spirit transaction is not &#147;reasonably capable of being consummated&#148; due to antitrust risk. As discussed in &#147;Background of the Solicitation&#148; below, we proposed a
contractual divestiture obligation with an express covenant to litigate and to divest assets of JetBlue and Spirit up to a material adverse effect on Spirit, with a limited <FONT STYLE="white-space:nowrap">carve-out</FONT> to this divestiture
obligation for actions that would represent a &#147;Burdensome Condition&#148; under JetBlue&#146;s Northeast Alliance, a commitment that we believe is sufficient to address any concerns the applicable regulatory authorities may have with our
proposed acquisition of Spirit. Furthermore, we proposed to proactively offer to divest any assets of Spirit located in New York and Boston, designed to address the Spirit Board&#146;s concern regarding our Northeast Alliance. In addition to our
agreement to pay to Frontier the $94.2&nbsp;million <FONT STYLE="white-space:nowrap">break-up</FONT> fee set forth in the Frontier Merger Agreement, as more fully discussed in &#147;Background of the Solicitation&#148; below, JetBlue has also
offered to pay a $350&nbsp;million &#147;reverse <FONT STYLE="white-space:nowrap">break-up</FONT> fee&#148; to Spirit in the event the proposed combination failed due to antitrust reasons, an unprecedented feature in airline industry mergers,
demonstrating our confidence in our ability to obtain the required antitrust approvals and further increasing the certainty of closing. In spite of these efforts, the Spirit Board has continued to refuse to meaningfully engage with us in
discussions. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The disclosures under the heading &#147;Background of the Solicitation&#148; beginning on page 3 of the Definitive Proxy Statement are

June&nbsp;3, 2022, on June&nbsp;2, 2022, Frontier, Spirit and Frontier Merger Sub entered into an amendment to the Frontier Merger Agreement (the &#147;<B>Amendment</B>&#148;) to include a reverse termination fee of $250,000,000, payable by Frontier
to Spirit in the event that the Frontier Merger Agreement is terminated due to either (i)&nbsp;a governmental authority issuing an order or taking any other action permanently enjoining or otherwise prohibiting the Proposed Frontier Merger under
U.S. federal competition laws or (ii)&nbsp;the Proposed Frontier Merger having not occurred by the Outside Date solely to the extent that the closing condition requiring the waiting period applicable to the consummation of the Proposed Frontier
Merger under the HSR Act to have expired or been terminated has not been satisfied at a time when all other closing conditions to Frontier&#146;s obligations to consummate the Proposed Frontier Merger have been satisfied (or are capable of being
satisfied if the closing were to occur on such date of termination). </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:9%; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Amendment also amends certain provisions of the
Frontier Merger Agreement relating to efforts to obtain regulatory approval of the Proposed Frontier Merger, including to provide that Frontier and Spirit, in connection with the receipt of any necessary approval of a governmental authority
(including under the HSR Act), will be required to take any divestiture actions, including selling, holding separate or otherwise disposing of any assets of Frontier, Spirit or their respective subsidiaries, unless such action would or would
reasonably be expected to result in a material adverse effect on Frontier and its subsidiaries (including Spirit) following the closing of the Proposed Frontier Merger when measured on a scale relative to Spirit. </P>
