~~During~~Merger the Company’s most recent fiscal years and the subsequent interim period preceding the change in principal accountants, the Company did not have any disagreements with BF Borgers on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of BF Borgers, would have caused it to make reference to the subject matter of the disagreement in connection with its report. No “reportable events” (as described in Item 304(a)(1)(v) of Regulation S-K) occurred within the Company’s most recent fiscal year or during the subsequent interim period preceding the change in principal accountants.Agreement

~~During~~The the Company’s most recent fiscal year and the subsequent interim period preceding the change in principal accountants, the Company did not consult Hudgens regarding: either the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements; or any matter that was either the subject of a disagreement (as described above) or a “reportable event” (as described in Item 304(a)(1)(v) of Regulation S-K).Transactions

~~Due~~Treatment toof ~~the~~SeeQC fact that BF Borgers is not currently permitted to appear or practice before the Commission, the Company has not furnished the disclosures in this Current Report with BF Borgers nor requested that BF Borgers provide a letter stating whether it agrees with the disclosures in this Current Report. Securities

Immediately prior to the effective time of the Merger (the “Effective Time”), all outstanding shares of preferred stock of SeeQC, par value $0.0001 per share (“SeeQC Preferred Stock”), will be mandatorily converted into shares of common stock of SeeQC, par value $0.0001 per share (“SeeQC Common Stock”), in accordance with the Company’s Certificate of Incorporation (the “Certificate of Incorporation”) in effect immediately before the Effective Time (the “SeeQC Preferred Stock Conversion”).

Immediately following the SeeQC Preferred Stock Conversion, but prior to the Effective Time, pursuant to an amendment to the Certificate of Incorporation, the outstanding shares of SeeQC Common Stock will be split, such that there the holders of Company Common Stock, as determined immediately following the Company Preferred Stock Conversion but prior to the Effective Time, will hold, in the aggregate, 200,000,0000 shares of SeeQC Common Stock (the “SeeQC Stock Split”), less the number of shares of SeeQC Common Stock issuable upon exercise, exchange or conversion of SeeQC’s derivative securities (after taking into account any adjustments to such securities as a result of the SeeQC Preferred Stock Conversion or the SeeQC Stock Split).

The stock options and restricted stock units of SeeQC outstanding as of the Effective Time will remain outstanding, subject to adjustment as necessary based on the SeeQC Stock Split.

Conversion of Allegro Securities

At the Effective Time, each share of common stock of Allegro, par value $0.0001 per share (“Allegro Common Stock”), and each right of Allegro (“Allegro Rights”), that is issued and outstanding immediately before the Effective Time (other than shares held by Allegro, SeeQC or their subsidiaries and shares as to which statutory dissenter’s rights have been exercised) will be canceled and converted into and become the right to receive one share of SeeQC Common Stock (multiplied by 1/10^th in the case of the Allegro Rights).

In connection with the Merger, Allegro will seek to amend its redeemable common stock purchase warrants, each entitling the holder thereof to purchase one share of Allegro Common Stock at an exercise price of $11.50 (collectively, “Allegro Warrants”), so that, immediately prior to the Effective Time, each of the issued and outstanding Allegro Warrants will automatically convert into the right to receive a fractional share of SeeQC Common Stock (the “Allegro Warrant Amendment”). In the event that the Allegro Warrants are not amended and the Merger is consummated, SeeQC will assume them.

SeeQC Earnout Shares

The holders of SeeQC Common Stock and the holders of certain of SeeQC’s equity compensation awards, each as of immediately prior to the Effective Time (the “Earnout Recipients”), are entitled to receive additional shares of SeeQC Common Stock if certain stock price conditions are met, as follows:

●

If, between the Closing and the first anniversary of the Closing (“Earnout Period 1”), the VWAP (as defined in the Merger Agreement) of the SeeQC Common Stock equals or exceeds $6.50 for 20 trading days within any 30 consecutive trading day period commencing after the Closing and ending on or prior to the end of such period (the “First Base Target”), then SeeQC will issue to the Earnout Recipients an aggregate of 20,000,000 shares of SeeQC Common Stock.

●

If, between the Closing and the second anniversary of the Closing (“Earnout Period 2”), the VWAP of the SeeQC Common Stock equals or exceeds $8.00 for 20 trading days within any 30 consecutive trading day period commencing after the Closing and ending on or prior to the end of such period (the “Second Base Target”), then SeeQC will issue to the Earnout Recipients an aggregate of 20,000,000 shares of SeeQC Common Stock, plus any shares not previously issued in respect of Earnout Period 1.

●

If, between the Closing and the third anniversary of the Closing (“Earnout Period 3”), the VWAP of the SeeQC Common Stock equals or exceeds $10.00 for 20 trading days within any 30 consecutive trading day period commencing after the Closing and ending on or prior to the end of such period (the “Third Base Target”), then SeeQC will issue to the Earnout Recipients an aggregate of 20,000,000 shares of SeeQC Common Stock, plus any shares not previously issued in respect of Earnout Period 1 and Earnout Period 2.

Allegro Sponsor Restricted Shares

Certain of the holders of the shares of Allegro Common Stock issued prior to Allegro’s initial public offering (such holders, the “initial stockholders,” and such shares, the “founder shares”) have agreed to restrictions on transfer with respect to 23% of the shares of SeeQC Common Stock to be received by them in the Merger and pursuant to the Allegro Warrant Amendment (other than shares of SeeQC Common Stock to be received by them in respect of the private placement units purchased by the initial stockholders simultaneously with Allegro’s initial public offering), with such restrictions to be released as follows:

●

If, during Earnout Period 1, the First Base Target is achieved, then 1/3 of the restricted shares will be released from the restrictions;

●

If, during Earnout Period 2, the Second Base Target is achieved, then 1/3 of the restricted shares will be released from the restrictions, plus any shares not released in respect of Earnout Period 1; and

●

If, during Earnout Period 3, the Third Base Target is achieved, then all of the restricted shares will be released from the restrictions.

If, at the end of Earnout Period 3, any restricted shares have not been released, then such shares will be forfeited by the initial stockholders of Allegro and cancelled by SeeQC.

There may be additional risks that none of SeeQC or Allegro presently know or currently believe are immaterial that could also cause actual results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and none of the parties or any of their representatives assumes any obligation, or intends, to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise.
