Authorized
Capital Stock


 


We
are presently authorized to issue 2,250,000 shares of common stock, $0.001 par value per share, of which 1,627,182 shares were
outstanding as of March 20, 2020. We are presently authorized to issue 10,000,000 shares of $0.001 par value preferred stock,

Preferred Stock and Series C Convertible Stock issued and outstanding, 880 shares of Series D Convertible Preferred Stock issued
and outstanding and 333.33 shares of Series E Convertible Preferred Stock issued and outstanding.


 


Common
Stock


 


We
have one class of common stock. Holders of our common stock are entitled to one vote per share on all matters to be voted upon
by stockholders and do not have cumulative voting rights in the election of directors. Holders of shares of common stock are entitled
to receive on a pro rata basis such dividends, if any, as may be declared from time to time by our board of directors in its discretion
from funds legally available for that use, subject to any preferential dividend rights of outstanding preferred stock. They are
also entitled to share on a pro rata basis in any distribution to our common stockholders upon our liquidation, dissolution or
winding up, subject to the prior rights of any outstanding preferred stock. Common stockholders do not have preemptive rights
to subscribe to any additional stock issuances by us, and they do not have the right to require the redemption of their shares
or the conversion of their shares into any other class of our stock. The rights, preferences and privileges of holders of common
stock are subject to, and may be adversely affected by, the rights of the holders of any series of preferred stock that we may
designate and issue in the future.

Public
Warrants


 


The
Public Warrants are exercisable at an exercise price of $40.00 per share, subject to certain adjustments. The Public Warrants
expire on February 21, 2022. Each Public Warrant will have a cashless exercise right in the event that shares of common stock
underlying such Warrants are not covered by an effective registration statement. As of December 31, 2019, we had 162,150 Public
Warrants outstanding.


 


Preferred
Stock


 


Under
our articles of incorporation, our board of directors has the authority, without further action by stockholders, to designate
one or more series of preferred stock and to fix the voting powers, designations, preferences, limitations, restrictions and relative
rights granted to or imposed upon the preferred stock, including dividend rights, conversion rights, voting rights, rights and
terms of redemption, liquidation preference and sinking fund terms, any or all of which may be preferential to or greater than
the rights of the common stock.


 


Our
board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect
the voting power or other rights of the holders of the common stock. The issuance of preferred stock, while providing flexibility
in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying,
deferring or preventing a change in our control and may adversely affect the market price of the common stock and the voting and
other rights of the holders of common stock.


 


In
connection with our underwritten public offering of equity securities on February 21, 2017, we created a series of Preferred Stock
called “Series A Preferred Stock.” None of such shares were issued in such offering. In our April 6, 2018 private
placement, we issued 1,000 shares of Series B Preferred Stock (“Series B Preferred”), which were convertible into
100,000 shares of common stock. All shares of our Series B Preferred have been converted and 50,000 shares of common stock issued
upon conversion of such shares are currently beneficially owned by an affiliate of a selling stockholder. In our June 26, 2018
public offering of equity securities, we issued 350 shares of Series C Preferred Stock which were initially convertible into 35,000
shares of common stock. Accordingly, as of the date of this Form 10-K, all shares of such preferred stock have been fully converted.
In connection with the private placements occurring on January 27, 2020, we created two new series of Preferred Stock: the Series
D Preferred Stock and the Series E Preferred Stock. As of the date of this Form 10-K, 880 shares of Series D Preferred Stock and
333.33 shares of Series E Preferred Stock are issued and outstanding.


 


Under
the Certificate of Designations for the Series D Preferred Stock, the Series D Preferred Stock has an initial stated value of
$1,000 per share (the “Stated Value”). Dividends accrue at a dividend rate of 9% per annum (subject to increase upon
the occurrence (and during the continuance) of certain triggering events described therein) will accrue and, on a monthly basis,
shall be payable in kind by the increase of the Stated Value of the Series D Preferred Shares by said amount. The holders of the
Series D Preferred Shares will have the right at any time to convert all or a portion of the Series D Preferred Shares (including,
without limitation, accrued and unpaid dividends and make-whole dividends through the third anniversary of the closing date) into
shares of the Company’s Common Stock at the conversion price then in effect, which initially is $10.00 (subject to adjustment
for stock splits, dividends, recapitalizations and similar events and full ratchet price protection). In addition, a holder may
at any time, alternatively, convert all, or any part, of its Series D Preferred Shares at an alternative conversion price, which
equals the lower of the applicable conversion price then in effect, and the greater of (x) $1.80 and (y) 85% of the average volume
weighted average price (“VWAP”) of the Common Stock for a five (5) trading day period prior to such conversion. Upon
the occurrence of certain triggering events, described in the Certificate of Designations, including, but not limited to payment
defaults, breaches of transaction documents, failure to maintain listing on the Nasdaq Capital Market, and other defaults set
forth therein, the Series D Preferred Shares would become subject to redemption, at the option of a holder, at a 125% premium
to the underlying value of the Series D Preferred Shares being redeemed.

The
Certificate of Designations contains a prohibition on the issuance of any shares of Common Stock upon conversion of the Series
D Preferred Shares in excess of the amount set forth in NASDAQ Listing Rule 5635(d) (20% or more of the outstanding shares of
common stock) until the Company obtains shareholder approval for issuance of shares of Common Stock in excess of such amount.
In the Institutional SPA, the Company has agreed to promptly obtain such shareholder approval and amend its article of incorporation
and/or effect a reverse split in order to have sufficient shares of Common Stock available to allow the holders of the Series
D Preferred Shares to convert in full the Series D Preferred Shares and exercise in full the Institutional Common Warrants.


 


Under
the Certificate of Designations for the Series E Preferred Stock, the Series E Preferred Shares have an initial stated value of
$1,500 per share (the “Stated Value”). Dividends at the initial rate of 9% per annum will accrue and, on a monthly
basis, shall be payable in kind by the increase of the Stated Value of the Series E Preferred Stock by said amount. The holders
of the Series E Preferred Shares have the right at any time to convert all or a portion of the Preferred Shares (including, without
limitation, accrued and unpaid dividends and make-whole dividends through the third anniversary of the closing date) into shares
of the Company’s Common Stock at an initial conversion rate determined by dividing the Conversion Amount by the Conversion
Price ($0.13 above the consolidated closing bid price for the trading day prior to the execution of the Securities Purchase Agreement,
dated January 27, 2020, between and the purchasers referenced therein). The Conversion Amount is the sum of the Stated Value of
the Series E Preferred Shares then being converted plus any other unpaid amounts payable with respect to the Series E Preferred
Shares being converted plus the “Make Whole Amount” (the amount of any dividends that, but for the conversion, would
have accrued at the dividend rate for the period through the third anniversary of the initial issuance date). The Conversion Rate
is also subject to adjustment for stock splits, dividends recapitalizations and similar events.

Anti-Takeover
Effects of Certain Provisions of Our Charter Documents


 


Our
articles of incorporation and bylaws contain provisions that could delay or prevent changes in control or changes in our management
without the consent of our board of directors. These provisions include the following:


 


	 	●	a classified
    board of directors with three-year staggered terms, which may delay the ability of stockholders to change the membership of
    a majority of our board of directors; 
	 	 	 
	 	●



	no cumulative voting
    in the election of directors, which limits the ability of minority stockholders to elect director candidates;



 






    	 	3	 



    	 



    

 


	 	●



	the exclusive right
    of our board of directors to elect a director to fill a vacancy created by the expansion of the board of directors or the
    resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of
    directors; 
	 	 	 
	 	●



	the ability of our
    board of directors to authorize the issuance of additional shares of preferred stock and to determine the terms of those shares,
    including preferences and voting rights, without stockholder approval, which could adversely affect the rights of our common
    stockholders or be used to deter a possible acquisition of our company; 
	 	 	 
	 	●



	the ability of our
    board of directors to alter our bylaws without obtaining stockholder approval; 
	 	 	 
	 	●



	the required approval
    of the holders of at least two-thirds of the shares entitled to vote at an election of directors to adopt, amend or repeal
    our bylaws or repeal the provisions of our articles of incorporation and bylaws regarding the election and removal of directors;
    
	 	 	 
	 	●



	a prohibition on stockholder
    action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;
    
	 	 	 
	 	●



	the requirement that
    a special meeting of stockholders may be called only by the chairman of the board of directors, the chief executive officer,
    the president or the board of directors, which may delay the ability of our stockholders to force consideration of a proposal
    or to take action, including the removal of directors; and 
	 	 	 
	 	●



	advance notice procedures
    that stockholders must comply with in order to nominate candidates to our board of directors or to propose matters to be acted
    upon at a stockholders’ meeting, which may discourage or deter a potential acquirer from conducting a solicitation of
    proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of us.


 


These
provisions could inhibit or prevent possible transactions that some stockholders may consider attractive.


 


NASDAQ
Capital Market


 


Our
Common Stock and Public Warrants are currently traded on the NASDAQ Capital Market under the symbols “SGLB” and “SGLBW”

Nevada
Anti-Takeover Law and Charter and Bylaws Provisions


 


NRS
sections 78.378 to 78.3793 provide state regulation over the acquisition of controlling interest in certain Nevada corporations
unless the articles of incorporation or bylaws of the corporation provide that the provisions of these sections do not apply.
This statute currently does not apply to our company because in order to be applicable, we would need to have a specified number
of Nevada residents as shareholders, and we would have to do business in Nevada directly or through an affiliate.
