As also previously reported on a Current Report on Form 8-K of GigCapital2, filed with the SEC on November 23, 2020, GigCapital2 announced that it executed a Business Combination Agreement, dated as of November 20, 2020, with Cloudbreak Health, LLC, a Delaware limited liability company (“Cloudbreak”), Cloudbreak Merger Sub, LLC, a Delaware limited liability company, solely with respect to Section 7.15 thereof, Chirinjeev Kathuria and Mariya Pylypiv and UpHealth, and Shareholder Representative Services LLC, a Colorado limited liability company, solely in its capacity as the representative, agent and attorney-in-fact of the Cloudbreak members (such business combination agreement, the “Cloudbreak BCA,” and, together with the UpHealth BCA, the “BCAs” and such business combination, the “Cloudbreak Combination” and, together with the UpHealth Combination, the “Business Combinations”).

This Current Report on Form 8-K provides a summary of other agreements entered into (and certain agreements to be entered into) in connection with the aforementioned Business Combinations. The descriptions of these agreements do not purport to be complete and are qualified in their entirety by the terms and conditions of such agreements or the forms thereof, as applicable, copies of which are filed as Exhibits 10.1 and 10.2 hereto and are incorporated by reference herein.

PIPE Subscription Agreement

On January 20, 2021, GigCapital2 entered into subscription agreements (the “PIPE Subscription Agreements”), each dated January 20, 2021, with certain institutional investors (the “PIPE Investors”), including Oppenheimer & Co. Inc., the placement agent for the private placements under the PIPE Subscription Agreements, pursuant to which, among other things, GigCapital2 agreed to issue and sell, in private placements to close immediately prior to the closing of the Business Combinations, an aggregate of 3,000,000 shares (the “PIPE Shares”) of GigCapital2’s common stock (the “Common Stock”) to the PIPE Investors at $10.00 per share.

The obligations to consummate the subscriptions are conditioned upon, among other things, all conditions precedent to the closing of the transactions contemplated by the Note Subscription Agreements (as defined below) having been satisfied or waived, and the closing of the transaction contemplated by the PIPE Subscription Agreements occurring concurrently with the closing of the transactions contemplated by the Note Subscription Agreements.

Pursuant to the PIPE Subscription Agreements, GigCapital2 agreed that, prior to the closing of the Business Combinations, GigCapital2 will file with the SEC (at GigCapital2’s sole cost and expense) a registration statement registering the resale of the PIPE Shares (the “Resale Registration Statement”), and GigCapital2 will use its commercially reasonable efforts to have the Resale Registration Statement declared effective upon the closing of the Business Combinations, but no later than 60 calendar days (or 90 calendar days if the SEC notifies GigCapital2 that it will not review the Resale Registration Statement) after the closing of the Business Combinations, subject to customary conditions and covenants.

The foregoing description of the PIPE Subscription Agreements and the transactions contemplated thereby is not complete and is subject to, and qualified in its entirety by reference to, the agreed upon form of PIPE Subscription Agreements, a copy of which is filed with this Current Report on Form 8-K as Exhibit 10.1, and the terms of which are incorporated herein by reference.

Notes Subscription Agreements and Indenture

On January 20, 2021, GigCapital2 also entered into convertible note subscription agreements (the “Note Subscription Agreements”), each dated January 20, 2021, with certain institutional investors (the “Note Investors”), pursuant to which GigCapital2 agreed to issue and sell, in a private placements to close immediately prior to the closing of the Business Combinations, $255,000,000 aggregate principal amount of unsecured convertible notes (the “Notes”).

The Notes are to be issued under an indenture to be entered into in connection with the closing of the Business Combinations, between UpHealth, Inc. (formerly GigCapital2) and Wilmington Trust, National Association, a national banking association, in its capacity as trustee thereunder (the “Indenture”).

The Notes will bear interest at a rate of 6.25% per annum, payable semi-annually, and be convertible into shares of Common Stock at a conversion price of $11.50 per share of Common Stock in accordance with the terms of the Indenture, and will mature five years after their issuance.

GigCapital2 may, at its election, force conversion of the Notes after the first anniversary of the issuance of the Notes, subject to a holder’s prior right to convert, if the last reported sale price of the Common Stock exceeds 130% of the conversion price for at least 20 trading days during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter, and the 30-day average daily trading volume of the Common Stock ending on, and including, the last trading day of the applicable exercise period is greater than or equal to $2,000,000. Following certain corporate events that occur prior to the maturity date or if GigCapital2 forces a mandatory conversion, GigCapital2 will, in certain circumstances, increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event or has its notes mandatorily converted, as the case may be. In addition, in the event that a holder of the Notes elects to convert its Notes prior to the second anniversary of the issuance of the Notes, GigCapital2 will be obligated to pay an amount equal to twelve months of interest, or if on or after such second anniversary of the issuance of the Notes, any remaining amounts that would be owed to, but excluding, the third anniversary of the issuance of the Notes (the “Interest Make-Whole Payment”). The Interest Make-Whole Payment will be payable in cash or shares of the Common Stock as set forth in the Indenture.

GigCapital2 will be obligated to register the shares issuable upon conversion of the Notes. GigCapital2 agreed that, within 45 days after the consummation of the Business Combinations (the “Convertible Note Resale Registration Filing Deadline”), GigCapital2 will file with the SEC a registration statement (the “Convertible Note Resale Registration Statement”) registering the resale of the shares of Common Stock issuable upon conversion of the Notes (the “Convertible Note Registrable Securities”), and GigCapital2 will use its commercially reasonable efforts to have the Convertible Note Resale Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the 60th calendar day (or 90th calendar day if the SEC notifies GigCapital2 that it will “review” the Convertible Note Resale Registration Statement) following the Convertible Note Resale Registration Filing Deadline.

The obligations of the Note Investors to consummate the subscriptions provided for in the Note Subscription Agreements are conditioned upon, among other things, GigCapital2 (i) having received cash and cash equivalents from the issuance and sale of the Notes of an aggregate amount not less than $150,000,000 and from the issuance and sale of the Common Stock of an aggregate amount not less than $30,000,000 and (ii) having at least $50,000,000 in the trust account after giving effect to any redemptions, and all conditions precedent to the closing of the transactions contemplated by the PIPE Subscription Agreements having been satisfied or waived, and the closing under the Note Subscription Agreements occurring concurrently with the investment by the PIPE Investors.
