DESCRIPTION OF SECURITIES

Common Stock:

Retractable Technologies, Inc. (“RTI”) is authorized to issue 100,000,000 shares of no par value Common Stock, of which 32,674,954 shares were issued and outstanding at December 31, 2019. Our Common Stock is listed on the NYSE American stock exchange under the symbol “RVP”.

The 2008 Stock Option Plan, which authorized a total of 6,000,000 shares of Common Stock upon the exercise of stock options, expired July 25, 2018. Options for the purchase of 639,300 shares under the 2008 Stock Option Plan were outstanding as of December 31, 2019.

RTI’s Preferred Stock is convertible into Common Stock with a conversion rate of one-for-one. There were 772,945 shares of Preferred Stock outstanding on December 31, 2019.

Shares of our Common Stock have no conversion rights, no preemptive rights, no restrictions on alienation, and are fully paid and are not liable to further call or assessment. Each share of our Common Stock is entitled to share ratably in any asset available for distribution to holders of its equity securities upon liquidation of RTI, subject to the preference of the holders of each class and series of the Preferred Stock. There are no restrictions on the transfer of our Common Stock other than as imposed by applicable federal and state securities laws.

All shares of our Common Stock have equal voting rights and, when validly issued and outstanding, have one vote per share on all matters to be voted upon by stockholders. The holders of the Common Stock elect the Directors subject to certain limited voting rights of the holders of the Series II Preferred Stock if dividends are in arrears for 12 consecutive quarters. Our Board of Directors is divided into two classes currently consisting of three Class 1 members and three Class 2 members with staggered terms. Generally, Directors serve for two-year terms. Cumulative voting in the election of Directors is prohibited.

Holders of our Common Stock are entitled to receive dividends when and if declared by the Board of Directors out of funds available therefor. We have not paid any dividends on the Common Stock since RTI’s inception and presently anticipate that no dividends on our Common Stock will be declared in the foreseeable future. Any future dividends will be subject to the discretion of the Board of Directors and will depend upon, among other things, future earnings, full payment of dividends on the Preferred Stock, our operating and financial condition, our capital requirements, and general business conditions.

Preferred Stock:

Our Board of Directors is authorized to divide each class of the preferred stock into series and to set the relative rights and preferences as to and between series, including dividends, issuance of preferred stock, redemption of such shares, and the conversion of any shares of preferred stock to other or common shares. RTI is authorized to issue 5,000,000 shares of Preferred Stock Class A with a par value of One Dollar ($1.00) per share; 5,000,000 shares of Preferred Stock Class B with a par value of One Dollar ($1.00) per share; and 5,000,000 shares of Preferred Stock Class C with a par value of One Dollar ($1.00) per share.

RTI has only one class of preferred stock outstanding: the Class B Convertible Preferred Stock (the “Preferred Stock”), which has five series: Series I, Series II, Series III, Series IV, and Series V.

The Class B Stock has been allocated among Series I, II, III, IV, and V in the amounts of 96,000; 171,200; 129,245; 342,500; and 34,000 shares, respectively as of December 31, 2019. The remaining 4,227,055 authorized shares have not been assigned a series.

This summary is not intended to be complete and is subject to, and qualified in its entirety by, reference to the Certificates of Designation, Preferences, Rights, and Limitations of Series I, II, III, IV, and V Class B Convertible Preferred Stock of RTI, filed with the Secretary of the State of Texas. The Certificates of Designation were filed as an Exhibit to our Form 10-Q filed on November 15, 2010.

The Preferred Stock is not listed on any securities exchange or automated dealer quotation system. The Series I Preferred Stock was created pursuant to a Board resolution in 1995 and was priced at $5.00 per share.
