Capitalized terms used in this Current Report on Form 8-K but not otherwise defined herein have the meanings given to them in the proxy statement/prospectus, dated December 12, 2022, that was filed by Tailwind with the SEC and distributed to its stockholders (the "Proxy Statement").

Additional Company Note

On December 14, 2022, Nuburu issued the New Company Note to NPIC Limited, an affiliate of Polar Asset Management Partners Inc., in the amount of $2.0 million. As previously disclosed in the Proxy Statement, the issuance of the New Company Note by Nuburu (and any other Company Notes in an aggregate amount not to exceed $50.0 million in the aggregate) is permitted under the terms of the Business Combination Agreement. As set forth in the Business Combination Agreement and as previously disclosed in the Proxy Statement, theNew Company Note will be (together with all other Company Notes) canceled and converted into shares of Nuburu Common Stock in accordance with the terms of such Company Note as of immediately prior to the Effective Time, which shares shall then be outstanding as of immediately prior to the Effective Time and subsequently converted into New Nuburu Common Stock (and with such shares being entitled to participate in the Preferred Stock Issuance).

Final Exchange Ratios

Tailwind and Nuburu have determined the Preferred Stock Exchange Ratios and Common Stock Exchange Ratio as of the anticipated date for Closing in accordance with the terms of the Business Combination Agreement.

As of the anticipated date for Closing, we currently estimate that the Common Stock Exchange Ratio and the Preferred Stock Exchange Ratios will be as follows.

Nuburu Series A-1 Preferred Stock 0.610
Nuburu Series B Preferred Stock 0.847
Nuburu Series B-1 Preferred Stock 0.525
Nuburu Series C Preferred Stock 1.032

Pursuant to the terms of the Business Combination Agreement, the final exchange ratios may differ from the foregoing, including if the Closing Date is more than 15 business days after the anticipated date for Closing.

These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Nothing in this report should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made.
