Blonder Tongue's product line can be separated, according to function, into the following categories: (i) headend products used by a system operator for signal acquisition, processing and manipulation for further transmission ("Headend Products"), (ii) distribution products used to permit signals to travel to their ultimate destination in a home, apartment unit, hotel room, office or other terminal location ("Distribution Products"), (iii) subscriber products (which include interdiction products) used to control access to programming at the subscriber's location and to split and amplify incoming signals for transmission to multiple sites and for multiple television sets within a site ("Subscriber Products") and (iv) microwave products used to transmit the output of Headend Products to multiple locations using point-to-point communication links in the 18 Ghz range of frequencies ("Microwave Products"). The Company's principal customers are system integrators, primarily in the Private Cable market, which design, package, install and in most instances operate cable systems. Blonder Tongue is a recognized leader in the Private Cable market, offering Private Cable integrators "one-stop shop" convenience in the form of a complete range of high performance, quality products at reasonable prices as well as product engineering, design and support. The Company offers its customers all components necessary to build a cable system, from Headend Products which serve as the core of any system, to ancillary components of the system which transmit, distribute and control access to cable signals. The Company was incorporated in November 1988, under the laws of the State of Delaware as a successor toGPS Acquisition Corp. for the purpose of acquiring the business of Blonder-Tongue Laboratories, Inc., a New Jersey corporation, operating under the same name, which was originally founded in 1950 by Ben H. Tongue and Isaac S. Blonder to design, manufacture and supply a line of electronics and systems equipment principally for the private cable industry. Following the acquisition, we changed our name to Blonder Tongue Laboratories, Inc. Blonder Tongue completed the initial public offering of its shares of common stock in 1950.December 1995.

Today, Blonder Tongue is a technology research and development (“R&D”) company with U.S.-based manufacturing, that delivers a wide range of products and services to major telecommunications, cable and fiber optic service delivery operators, as well as broadcasters and media production companies. For over 70 years, our products have provided the latest technology for telecom company Central Offices (COs), cable operator headends, broadcaster studios (together “Telecom”), as well as to lodging/hospitality, multi-dwelling units/apartments (“MDU”) and a range of business to business (“B-B”) customers at a wide range of locations including university campuses, healthcare/hospitals, fitness centers, government facilities, military bases, prisons, airports, sports stadiums/arenas, entertainment venues/casinos, retail stores, and small-medium businesses. These applications are also variously described as commercial, institutional, and/or enterprise environments and will be referred to herein collectively as “CIE.” The Company'scustomers we serve also include business entities distributing and installing private data delivery, broadband and video networks in these environments, including the world’s largest cable television operators, telecommunications providers and satellite providers, as well as integrators, architects, engineers or the next generation of Internet Protocol Television (“IPTV”) streaming video service providers.

We continue to be focused on the needs of an expanding group of customers, providing high quality, ultra-high reliability technology products to meet their needs and supporting those products following deployment. For over 70 years we have provided innovative solutions based on continually advancing technology. Since our founding, Blonder Tongue has continued to keep abreast of evolving technologies, from analog to digital television, Hybrid-Fiber Coax (“HFC”) networks with Quadrature Amplitude Modulation (“QAM”) edge devices, High Definition (“HD”) and Ultra HD (“4K”) and (“UHD”) encoding and transcoding, IPTV processing and distribution, multiscreen Adaptive Bit Rate (“ABR”) technologies and high-speed data delivery technologies.

Beginning in January 2020, Blonder Tongue has been implementing a strategic plan to improve operating results towards increasing shareholder value. This plan consists of:

oAdapting operating expenses in line with expected revenue and income levels.
oFocusing R&D on short-term high confidence opportunities with compelling ROI.
oExpanding sales and marketing efforts directly to service operators.
oStreamlining manufacturing operations and simplifying product offerings.
oIncreasing gross margins.

In 2019, Blonder Tongue initiated a consumer premise equipment (“CPE”) sales initiative. The products sold in 2019 comprise primarily Android-based IPTV set top boxes targeted to the Tier 2 and Tier 3 telecommunications and fiber optics-based service providers. Total CPE product sales, including product accessories and replacement parts, were $4,165,000 in 2020 and $3,977,000 in 2019.

Like many businesses throughout the United States and the world, we have been affected by the COVID-19 outbreak. Because there are daily developments regarding the outbreak, we are continually assessing the current and anticipated future effects on our business, including how these developments are impacting or may impact our customers, employees and business partners. In our core CIE business, we have experienced a noticeable decline in sales, as many of our customers have significantly reduced their business operations. In our CPE business we have experienced a more substantial reduction in sales, again as a result of our customers’ significant decrease in their business activities. With uncertainties surrounding the extent to which the COVID-19 outbreak will affect the economy generally, and our customers and business partners in particular, it is impossible for us to predict when conditions will improve to the point that we can reasonably forecast when our sales might return to historical levels. However, we are currently taking steps to significantly reduce our expenses, including adjustments in our staffing (in the form of furloughs) and reductions in manufacturing activities, which we believe will improve our ability to continue our operations at current levels and meet our obligations to our customers.

Our manufacturing is allocated primarily between its facility in Old Bridge, New Jersey (“Old Bridge Facility”) and key contract manufacturing located in the People’s Republic of China (“PRC”) as well as South Korea, Taiwan and Ohio. We currently manufacture most of our digital products, including the NXG product line and latest encoder, transcoder and EdgeQAM collections at the Old Bridge Facility. Since 2007 we have transitioned and continue to manufacture certain high volume, labor intensive products, including many of our analog and other products, in the PRC, pursuant to manufacturing agreements that govern the production of products that may from time to time be the subject of purchase orders submitted by (and in the discretion of) Blonder Tongue. Although we do not currently anticipate the transfer of any additional products to the PRC or other countries for manufacture, we may do so if business and market conditions make it advantageous to do so. Manufacturing products both at the Old Bridge Facility as well as in the PRC, South Korea, Taiwan and Ohio enables Blonder Tongue to realize cost reductions while maintaining a competitive position and time-to-market advantage.

The Company may, from time to time, provide manufacturing, research and development and product support services for other companies’ products. In 2015, the Company entered into an agreement with VBrick Systems, Inc. (“VBrick”) to provide procurement, manufacturing, warehousing and fulfillment support to VBrick for a line of high-end encoder products and sub-assemblies. Sales to VBrick of encoder products were approximately $145,000 and $602,000 in 2020 and 2019, respectively. Sales to VBrick for sub-assemblies were not material in 2020 or 2019.

The prospectus supplement will also contain information, where applicable, about material United States federal income tax considerations relating to the offered securities, and the securities exchange, if any, on which the offered securities will be listed. The descriptions herein and in the applicable prospectus supplement do not contain all of the information that you may find useful or that may be important to you. You should refer to the provisions of the actual documents whose terms are summarized herein and in the applicable prospectus supplement, because those documents, and not the summaries, define your rights as holders of the relevant securities. For more information, please review the forms of these documents, which are or will be filed with the SEC and are or will be available as described under the heading “Where You Can Find More Information” below.


DESCRIPTION OF COMMON STOCK

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the common stock that we may offer under this prospectus or any prospectus supplement. The following description provides a summary of the terms of our common stock, but does not purport to be complete and is subject to and qualified by reference to our certificate of incorporation and bylaws, as amended to date, which have been filed with or incorporated by reference in the registration statement of which this prospectus is a part.

The description below does not contain all of the information that you might find useful or that might be important to you. You should refer to the provisions of our certificate of incorporation and bylaws because they, and not the summaries, define the rights of holders of shares of our common stock. These documents are available as described under the heading “Where You Can Find More Information.”

General

Our certificate of incorporation authorizes the issuance of up to 25,000,000 shares of common stock and 5,000,000 shares of preferred stock. The rights and preferences of the preferred stock may be established from time to time by our board of directors. As of April 16, 2021, there were 11,960,505 shares of common stock issued and outstanding and no shares of preferred stock issued and outstanding.

Voting Rights

Except as otherwise indicated,required by law and except as usedprovided by the terms of any other class or series of stock, holders of common stock have the exclusive power to vote on all matters presented to our stockholders, including the election of directors. Each holder of common stock is entitled to one vote per share, and each holder does not have cumulative voting rights. Accordingly, the holders of a majority of the shares of common stock entitled to vote in this Prospectus,any election of directors can elect all of the "Company"directors standing for election if they so choose. All matters are decided by the vote of a majority in voting interest of the stockholders present in person or by proxy and "Blonder Tongue" refervoting at any meeting of the stockholders during which a quorum is present, except as otherwise provided in our certificate of incorporation, our bylaws or by applicable law.

Because our certificate of incorporation permits our board of directors to Blonder Tongue Laboratories, Inc.set the voting rights of preferred stock, it is possible that holders of one or more series of preferred stock issued in the future could have voting rights that might limit the effect of the voting rights of holders of common stock.

Dividend Rights; Liquidation Rights

Subject to preferences that may be applicable to any then outstanding preferred stock, holders of common stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by the board of directors out of legally available funds. In addition, we may be party to one or more agreements, such as loan agreements and its subsidiaries. RISK FACTORS credit facilities, that will contractually limit our ability to pay dividends.

Because our certificate of incorporation permit our board of directors to set the dividend rights of preferred shares, it is possible that holders of one or more series of preferred shares issued in the future could have dividend rights that differ from those of the holders of our common stock. If the holders of a class or series of preferred stock is given dividend rights, the right of holders of preferred shares to receive dividends could have priority over the right of holders of our common stock to receive dividends.

We have followed and presently intend to continue following a policy of retaining earnings, if any. We have not historically declared or paid dividends on our common stock, and we do not expect to do so in the foreseeable future. Any future determination relating to our dividend policy will be made at the discretion of our board of directors and will depend on a number of factors, including our earnings and financial condition, liquidity and capital requirements, the general economic and regulatory climate, our ability to service any equity or debt obligations senior to our common stock, and other factors deemed relevant by our board of directors. 


In evaluating the Company's businessevent of our liquidation, dissolution or winding up, holders of common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and in making a decision to purchase Common Stock, prospective investors should carefully considerother liabilities and the following factors in additionsatisfaction of any liquidation preference granted to the holders of any outstanding shares of preferred stock.

The effects of products (beyond outstanding purchase orders) or to provide the Company with binding forecasts of product purchases for any future period. The complement of leading customers may shift as the most efficient and better financed integrators grow more rapidly than others. The Company believes that many integrators will grow rapidly, and, as such, the Company's success will depend in part on the viability of those customers and on the Company's ability to maintain its position in the overall marketplace by shifting its emphasis to those customers with the greatest growth and growth prospects. Any substantial decrease or delay in sales toissuing preferred stock could include one or more of the Company's leading customers, the financial failurefollowing:

decreasing the amount of earnings and assets available for distribution to holders of common stock; 

restricting dividends on the common stock;

diluting the voting power of the common stock;

impairing the liquidation rights of the common stock; or

Effect of anyCertain Provisions of these entities, or the Company's inability to develop solid relationships with the integrators which may replace the present leading customers, could have a material adverse effect on the Company's resultsour Certificate of operationsIncorporation and financial condition. 4 Need to Manage Growth; Scientific Acquisition The Company has recently experienced a period of significant growth which has placed, and could continue to place, a significant strain on the Company's resources, including its working capital. Cash flow from operations has been insufficient to finance this growthBylaws and the Company has relied upon a lineDelaware Anti-Takeover Statute

Some provisions of credit to supplement cash generated from operations to finance working capital requirements. The Company's ability to manage growth effectively will require it to continue to improveDelaware law and expand its operations, including its financialour certificate of incorporation and management information systems and its manufacturing operations and to recruit and retain executive staff and key employees. There can be no assurance thatbylaws could make the Company's operations will generate sufficient cash flow or that adequate financing will be available to finance continued growth. The Company's inability to obtain needed equity or debt financing could have a material adverse effect on the Company's results of operations and financial condition. In addition, there can be no assurance that the Company will be able to continue to improve and expand its operations or to recruit and retain high quality executives and key employees. The failure to manage growth effectively would have a material adverse effect on the Company's results of operations and financial condition. In March, 1998, the Company acquired Scientific's interdiction business, including its interdiction product line (the "Acquisition"). The total purchase price consisted of (i) $19 million in cash, (ii) 67,889 shares of the Company's Common Stock, (iii) a Warrant to purchase 150,000 additional shares of the Company's Common Stock at an exercise price of $14.25 per share and (iv) assumption by the Company of certain obligations under executory contracts with vendors and customers and certain warranty obligations and other current liabilities of Scientific's interdiction business. As a result of the Acquisition, the Company acquired a new interdiction product line (the "SMI Product Line") which the Company believes will complement its current interdiction products and will enable it to increase sales in the CATV market. The success of the SMI Product Line will, however, be dependent upon the Company's ability to timely integrate the new products into the Company's existing operations, obtain manufacturing efficiencies, and maintain and increase market share in the CATV market. There can be no assurance that the new products will be successfully integrated by the Company or that such integration will not strain the Company's available management, manufacturing, financial and other resources. There can be no assurance that the Company will maintain the level of sales of the SMI Product Line in the CATV market or that increased sales of the SMI Product Line will not decrease sales of the Company's other products, including the Company's VideoMask(TM) interdiction product line. The Company's inability to integrate the SMI Product Line in a timely manner could have a material adverse effect on the Company's results of operations and financial condition. The Company currently has no commitments with respect to any future acquisitions. The Company, however, frequently evaluates the strategic opportunities available to it and, as part of its strategy to increase growth through acquisition, may in the future pursue acquisitions of additional complementary products, technologies and businesses. Such acquisitions by the Company may result in the diversion of management's attention from the day-to-day operations of the Company's business and may include numerous other risks, including difficulties in the integration of the operations and products, integration and retention of personnel of the acquired companies and certain financial risks. Future acquisitions by the Company may result in dilutive issuances of equity securities, the incurrence of additional debt, reduction of existing cash balances, amortization expenses related to goodwill and other intangible assets and other charges to operations that could have a material adverse effect on the Company's results of operations and financial condition. Changes in Technologies, Industry Standards and Customers' Needs Both the Private Cable industry and the CATV industry are characterized by the continuing advancement of technology, evolving industry standards and changing customer needs. To be successful, the Company must anticipate the evolution of industry standards and changes in customer needs, through the timely development and introduction of new products, enhancement of existing products and licensing of new technology from third parties. Although the Company depends primarily on its own research and development efforts to develop new products and enhancements to its existing products, the Company has and may continue to seek licenses for new technology from third parties when the Company believes that it can obtain such technologyfollowing transactions more quickly and/or cost-effectively from such third parties than the Company could otherwise develop on its own, or when the desired technology has already been patented by a third party. There can, however, be no assurance that new technology or such licenses will be available on terms acceptable to the Company. There can be no assurance that the Company will anticipate the evolution of industry standards in Private Cable, CATV or the communications industry generally, changes in the market and customer needs, or that technologies and applications under development by the Company will be successfully developed, or if they are successfully developed, that they will achieve market acceptance. If the Company is unable for technological or other reasons to develop and introduce products and applications or to obtain licenses for new technologies from third parties in a timely manner in response to changing market conditions or customer requirements, the Company's results of operations and financial condition would be materially adversely affected. 5 Highly Competitive Market Place All aspects of the Company's business are highly competitive. The Company competes with national, regional and local manufacturers and distributors, including companies larger than itself which have substantially greater resources. Various manufacturers who are suppliers to the Company sell directly as well as through distributors into the CATV and Private Cable marketplaces. Because of the convergence of the cable, telecommunications and computer industries and rapid technological development, new competitors may seek to enter the principal markets served by the Company. Many of these potential competitors have significantly greater financial, technical, manufacturing, marketing, sales and other resources than the Company. The Company expects that direct and indirect competition will increase in the future. Additional competition could have a material adverse effect on the Company's results of operations and financial condition through price reductions, loss of market share and delays in the timing of customer orders and an inability to increase its penetration into the CATV market. Dependence on Cable Industry Capital Spending The Company estimates that approximately 80% of its revenues in fiscal years 1995, 1996 and 1997 came from worldwide sales of its products for use primarily in Private Cable systems. Demand for the Company's products depends to a large extent upon capital spending on Private Cable systems and specifically by Private Cable operators for constructing, rebuilding, maintaining or upgrading their systems. Capital spending by Private Cable operators and, therefore, the Company's sales and profitability, are dependent on a variety of factors, including access by Private Cable operators to financing, demand for their cable services, availability of alternative video delivery technologies, and general economic conditions. In addition, since a principal strategy of the Company's growth plan anticipates deeper penetration into the CATV market, the Company's sales and profitability may in the future be more dependent on capital spending by traditional franchise cable system operators as well as by new entrants to this market planning to over-build existing cable system infrastructures, for constructing, rebuilding, maintaining and upgrading their systems. There can be no assurance that system operators in Private Cable or CATV will continue capital spending for constructing, rebuilding, maintaining, or upgrading their systems. Any substantial decrease or delay in capital spending by Private Cable or CATV operators would have a material adverse effect on the Company's results of operations and financial condition. Dependence on Single Manufacturing Facility The Company operates out of one manufacturing facility in Old Bridge, New Jersey (the "Old Bridge Facility"). While the Company maintains a limited amount of business interruption insurance, a casualty that results in a lengthy interruption of the ability to manufacture at that facility would have a material adverse effect on the Company's results of operations and financial condition. Dependence on Third Party Suppliers The Company purchases several products from sole suppliers for which alternative sources are not available, such as the VideoCipher(R) and DigiCipher(R) encryption systems manufactured by General Instrument Corporation, which are standard encryption methodology employed on United States C-Band and Ku-Band transponders, certain components of EchoStar digital satellite receiver decoders, which are specifically designed to work with the DISH Network(TM), and certain components of Hughes Network Systems digital satellite receivers which are specifically designed to work with DIRECTV(R) programming. Presently, the subscriber modules used in the Company's SMI Product Line acquired from Scientific in March, 1998, are manufactured for the Company by Matsushita Electronic Components Co., Ltd. pursuant to a supply contract. While the Company intends to develop this capability, there are no assurances that it will successfully be able to do so. An inability to timely obtain sufficient quantities of these components could have a material adverse effect on the Company's results of operations and financial condition. In addition, results of operations and financial condition could be materially adversely affected by receipt of a significant number of defective components, an increase in component prices or the inability of the Company to obtain lower component prices in response to competitive pressures on the pricing of the Company's products. Dependence on Internal Sales Force The Company historically maintained contractual relationships with numerous independent sales representatives; however, in February, 1998, the Company terminated almost all of its contractual relationships with its independent sales representatives. The Company intends to retain independent sales representatives only in particular geographic areas, such as the European market, or targeted to specific customer prospects. While management believes its internal sales force has the capacity to maintain or increase sales formerly made through independent sales representatives without the necessity of paying sales commissions, there can be no assurance that the internal sales force can maintain the historic levels of sales formerly made through the independent sales representatives or that additional employees will not need to be hired by the Company to expand the internal sales force. The Company's results of operations and financial condition could be 6 materially adversely affected if the internal sales force cannot maintain and increase the amount of sales formerly produced by the independent sales representatives. Risks of International Operations Sales to customers outside of the United States represented approximately 9%, 5% and 3% of the Company's revenues in fiscal years 1995, 1996 and 1997, respectively. Such sales are subject to certain risks such as changes in foreign government regulations and telecommunications standards, export license requirements, tariffs and taxes, other trade barriers, fluctuations in foreign currency exchange rates, difficulties in staffing and managing foreign operations, and political and economic instability. Fluctuations in currency exchange rates could cause the Company's products to become relatively more expensive to customers in a particular country, leading to a reduction in sales or profitability in that country. There can be no assurance that sales to customers outside the United States will reach or exceed historical levels in the future, or that international markets will continue to develop or that the Company will receive additional contracts to supply its products for use in systems and equipment in international markets. The Company's results of operations and financial condition could be materially adversely affected if international markets do not continue to develop, the Company does not continue to receive additional contracts to supply its products for use in systems and equipment in international markets or the Company's international sales are affected by the other risks of international operations. Limited Proprietary Protection Other than the SMI Product Line acquired by the Company from Scientific, the underlying technology for which is covered by numerous U.S. and international patents, the Company possesses limited patent or registered intellectual property rights with respect to its technology. The Company relies on a combination of contractual rights and trade secret laws to protect its proprietary technology and know-how. There can be no assurance that the Company will be able to protect its technology and know-how or that third parties will not be able to develop similar technology independently. Therefore, existing and potential competitors may be able to develop similar products which compete with the Company's products. Such competition could adversely affect the prices for the Company's products or the Company's market share and could have a material adverse effect upon the Company's results of operations and financial condition. Risk of Patent Infringement Claims While the Company does not believe that its products (including products and technologies licensed from others) infringe the proprietary rights of any third parties, there can be no assurance that infringement or invalidity claims (or claims for indemnification resulting from infringement claims) will not be asserted against the Company or its customers. Damages for violation of third party proprietary rights could be substantial, in some instances are trebled, and could have a material adverse effect on the Company's financial condition and results of operation. Regardless of the validity or the successful assertion of any such claims, the Company would incur significant costs and diversion of resources with respect to the defense thereof which could have a material adverse effect on the Company's financial condition and results of operations. If the Company is unsuccessful in defending any claims or actions that are asserted against the Company or its customers, the Company may seek to obtain a license under a third party's intellectual property rights. There can be no assurance, however, that under such circumstances, a license would be available under reasonable terms or at all. The failure to obtain a license to a third party's intellectual property rights on commercially reasonable terms could have a material adverse effect on the Company's results of operations and financial condition. Risks of Governmental Regulation Private Cable (estimated by the Company to represent approximately 80% of its business), while in some cases subject to certain FCC licensing requirements, is not presently burdened with extensive government regulations. difficult:

acquisition of us by means of a non-negotiated tender offer or similar transaction; 

a change of control by means of a proxy contest or other; or 

removal of our incumbent directors.


It is possible however, that regulations could be adopted in the future which impose burdensome restrictions on Private Cable operators resulting in, among other things, barriers to the entry of new competitors or limitations on capital expenditures by Private Cable operators. Any such regulations, if adopted, could have a material adverse effect on the Company's results of operations and financial condition. Operators in the CATV market (estimated by the Company to represent approximately 20% of its business) had been subject to extensive government regulation pursuant to the Cable Television Consumer Protection and Competition Act of 1992, which among other things provided for rate rollbacks for basic tier cable service, further rate reductions under certain circumstances and limitations on future rate increases. The Telecommunications Act of 1996 has deregulated many aspects of CATV system operation and has opened the door to competition among cable operators and telephone companies in each of their respective industries. The Company believes that this legislation will increase the base of potential customers for the Company's products. It is possible, however, that regulations could be adopted in the future which would re-impose burdensome restrictions on CATV operators resulting in, among other things, the grant of exclusive rights or franchises within certain geographical areas. Any increased regulation of CATV could have a material adverse effect on the Company's results of operations and financial condition. 7 Environmental Regulations The Company is subject to a variety of federal, state and local governmental regulations related to the storage, use, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in its manufacturing processes. The Company does not anticipate material capital expenditures during the remainder of its current fiscal year or during 1999, for compliance with federal, state and local environmental laws and regulations. There can be no assurance, however, that changes in environmental regulations will not result in the need for additional capital expenditures or otherwise impose additional financial burdens on the Company. Further, such regulations could restrict the Company's ability to expand its operations. Any failure by the Company to obtain required permits for, control the use of, or adequately restrict the discharge of, hazardous substances under present or future regulations could subject the Company to substantial liability or could cause its manufacturing operations to be suspended. Such liability or suspension of manufacturing operations could have a material adverse effect on the Company's results of operations and financial condition. Dependence on Key Personnel The Company's future success depends in large part on the continued service of its key executives and technical and management personnel, including James A. Luksch, Chief Executive Officer and President, and Robert J. Palle, Executive Vice President and Chief Operating Officer. The Company maintains and is the beneficiary of $1,000,000 of key man life insurance on each of Mr. Luksch and Mr. Palle. The Company's future success also depends on its ability to continue to attract and retain highly-skilled engineering, manufacturing, marketing and managerial personnel. The competition for such personnel is intense, and the loss of key employees, in particular the principal members of its management and technical staff, could have a material adverse effect on the Company's results of operations and financial condition. Control of the Company by Principal Stockholders, Officers and Directors Immediately following this offering, the Company's principal stockholders, officers and directors will beneficially own approximately 63% of the outstanding shares of the Company's Common Stock. As a result, such persons, acting together, would have the ability to control all matters requiring stockholder approval. The concentration of ownership could have the effect of discouraging offers to acquire the Company or otherwise inhibiting a change in control of the Company, and as a result, may deprive stockholders of an opportunity to sell their stock at higher prices. Potential Issuance of Preferred Stock and other Anti-Takeover Measures The Board of Directors has the authority to issue up to 5,000,000 shares of undesignated Preferred Stock, to determine the powers, preferences and rights and the qualifications, limitations or restrictions granted to or imposed upon any unissued series of undesignated Preferred Stock and to fix the number of shares constituting any series and the designation of such series, without any further vote or action by the Company's stockholders. The Preferred Stock could be issued with voting, liquidation, dividend and other rights superior to the rights of the Common Stock. Furthermore, such Preferred Stock may have other rights, including economic rights, senior to the Common Stock, and as a result, the issuance of such stock could have a material adverse effect on the market value of the Common Stock. In addition, the Company's Restated Certificate of Incorporation eliminates the right of stockholders to act without a meeting, does not provide cumulative voting for the election of directors or the right of stockholders to call special meetings, provides for a classified board of directors, and imposes various procedural requirements whichthese provisions could make it more difficult to accomplish or could deter transactions that shareholders may otherwise consider to be in their best interest or in our best interest, including transactions which provide for such stockholders to affect certain corporate actions. payment of a premium over the market price for our shares.

These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the Board'sbenefits of the increased protection of our potential ability to issue Preferred Stocknegotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.

Provisions of Our Governing Documents. Our certificate of incorporation and bylaws include provisions that may have the effecteffects summarized above. These provisions:

empower our board of directors, without stockholder approval, to issue preferred stock, the terms of which, including voting power, are set by our board of directors; 

divide our board of directors into three classes serving staggered three-year terms; 

restrict the ability of stockholders to remove directors; 

prohibit action by the stockholders without a stockholder meeting; 

eliminate cumulative voting in elections of directors; 

require that shares representing at least two-thirds of the total voting power approve any amendment to or repeal of our bylaws; 

require advance notice of nominations for the election of directors and the presentation of stockholder proposals at meetings of stockholders; and 

allow the board of directors to increase or decrease the number of directors.

Provisions of deterring hostile takeovers or offers from third partiesApplicable Law – Delaware Anti-Takeover Statute. We are subject to acquire the Company, preventing stockholders from receiving a premium for their shares of the Company's Common Stock, or delaying or preventing changes in control or management of the Company. The Company is also afforded the protection of Section 203 of the Delaware General Corporation Law which could delay or prevent(“DGCL”). This law prohibits a changepublicly held Delaware corporation from engaging in controlany business combination with any interested stockholder for a period of three years following the date that the stockholder became an “interested stockholder” unless:

prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; 

upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned by persons who are directors and also officers and by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or 

on or subsequent to the date of the transaction, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.



Section 203 defines “business combination” to include:

any merger or consolidation involving the corporation and the interested stockholder;

any sale, transfer, pledge or other disposition of 10% or more of our assets involving the interested stockholder;

in general, any transaction that results in the issuance or transfer by us of any of our stock to the interested stockholder; or 

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 of the Company, impedeDGCL defines an “interested stockholder” as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

Limitation of Liability and Indemnification

Section 145 of the DGCL allows us to indemnify any person who was or is a merger, consolidationparty or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was our director, officer, employee or agent, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other business combination involvingenterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the Companyperson in connection with such action, suit or discourageproceeding if the person acted in good faith and in a potential acquirormanner the person reasonably believed to be in or not opposed to our best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. Section 145 further allows us to indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in our favor, by reason of the fact that the person is or was our director, officer, employee or agent, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to our best interests and except that no indemnification is permitted in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to us, unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought determines that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court deems proper.

Section 102(b)(7) of the DGCL permits us to include in our certificate of incorporation a provision eliminating or limiting the personal liability of a director to us or our stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to unlawful payment of dividends and unlawful stock purchase and redemption) or (iv) for any transaction from makingwhich the director derived an improper personal benefit.


Our certificate of incorporation provides that our directors shall not be liable to Blonder Tongue or our stockholders for monetary damages for breach of fiduciary duty as a tender offerdirector except to the extent that exculpation from liabilities is not permitted under the DGCL as in effect at the time such liability is determined. In addition, our certificate of incorporation and our bylaws each include provisions requiring us to indemnify directors and officers to the fullest extent permitted by the DGCL. Our certificate of incorporation and bylaws provide that any person made a party or threatened to be made a party to a threatened, pending or completed action, suit or proceeding by reason of the fact that such person is or was a director or officer of ours, is or was serving at our request as a director or officer of another corporation or enterprise, including service with respect to an employee benefit plan, shall be indemnified by us against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding to the fullest extent authorized from time to time by the DGCL. The rights of indemnification are not exclusive of any other rights to which those seeking indemnification may be entitled and shall continue as to a person who ceases to be a director, officer, employee or agent.

We have obtained director and officer liability insurance under which, subject to the limitations of such policies, coverage will be provided (a) to directors and officers against loss arising from claims made by reason of breach of fiduciary duty or other wrongful acts as a director or officer, including claims relating to public securities matters and (b) to us with respect to payments which we may make to our directors and officers pursuant to the indemnification provisions summarized above or otherwise attemptingas a matter of law.

We also have entered into indemnification agreements with our directors and officers. The indemnification agreements provide directors and officers with further indemnification to obtain controlthe maximum extent permitted by the DGCL.

We believe that the foregoing policies and provisions of our governing documents are necessary to attract and retain qualified officers and directors. Insofar as indemnification for liabilities arising under the Securities Act may be permitted with respect to our directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the Company.SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

DESCRIPTION OF PREFERRED STOCK

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the preferred stock that we may offer under this prospectus. While the terms summarized below will apply generally to any shares of preferred stock that we may offer, we will describe the particular terms of any series of preferred stock in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any shares of preferred stock offered under that prospectus supplement may differ from the terms described below. Specific certificates of designation will contain additional important terms and provisions and will be incorporated by reference as an exhibit to the registration statement that includes this prospectus. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the certificate of designation that contains the specific terms of the shares of any preferred stock we offer for sale.

General

Under the terms of our certificate of incorporation, our board of directors is authorized, subject to any limitations prescribed by law, without stockholder approval, to issue up to a maximum of 5,000,000 shares of preferred stock in one or more series, with such rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, as determined by the board of directors. As of the date of this prospectus, we do not have any shares of preferred stock outstanding.

The rights and privileges relating to any shares preferred stock we issue will be set forth in a certificate of designation. If we do issue any shares of preferred stock, we will make available the related certificate of designation. The terms included in the certificate of designation will provide additional detail and may be different than those summarized below. Because the certificate of designation will govern the shares of any preferred stock we issue, you should review the certificate of designation as that document, and not this summary, will define the rights and privileges of such shares.

In authorizing the issuance of any additional shares of our preferred stock, our board of directors may determine the following:

the voting powers, if any, of the holders of shares of such series in addition to any voting rights affirmatively required by law; 

the rights of stockholders in respect of dividends, including, without limitation, the rate or rates per annum and the time or times at which (or the formula or other method pursuant to which such rate or rates and such time or times may be determined) and conditions upon which the holders of shares of such series will be entitled to receive dividends and other distributions, and whether any such dividends will be cumulative or noncumulative and, if cumulative, the terms upon which such dividends will be cumulative; 

whether the shares of each such series shall be redeemable by us at our option or the holder of the shares, and, if redeemable, the terms and conditions upon which the shares of such series may be redeemed; 

the amount payable and the rights or preferences to which the holders of the shares of such series will be entitled upon any voluntary or involuntary liquidation, dissolution or winding-up;
the terms, if any, upon which shares of such series will be convertible into, or exchangeable for, shares of any other class or classes or of any other series of the same or any other class or classes, including the price or prices or the rate or rates of conversion or exchange and the terms of adjustment, if any; and
any other designations, preferences, and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof, so far as they are not inconsistent with the provisions of our certificate of incorporation and to the full extent now or hereafter permitted under Delaware law.


Terms

You should read the applicable prospectus supplement relating to the particular series of preferred stock being offered and issued and the related certificate of designation for specific terms of the shares of preferred stock of such series, including, where applicable:

the title of the series, stated value and liquidation preferences, the number of shares constituting the series and the number of shares of the series that are being offered; 

the price or other consideration for which the shares will be issued; 

the dividend rate(s) (or method of calculation), the dividend periods, the dates on which dividends shall be payable and whether the dividends will be cumulative or noncumulative and, if cumulative, the dates at which the dividends shall begin to cumulate, and the participating and other rights, if any, with respect to dividends; 

the redemption or sinking fund provisions, if any;
whether the shares will be convertible into, or exchangeable for, shares of any other class or series and, if so, the provisions relating to conversion or exchange rights;
the voting powers, full or limited, if any, of the shares offered; and
such other powers, preferences, rights, qualifications, limitations and restrictions thereof as our board of directors may deem advisable.

When we issue shares of preferred stock, the shares will be fully paid and nonassessable, which means the full purchase price of the shares will have been paid and holders of the shares will not be assessed any additional monies for the shares. Unless the applicable prospectus supplement indicates otherwise, each series of the preferred stock will rank equally with any outstanding shares of our preferred stock and each other series of the preferred stock. Unless the applicable prospectus supplement states otherwise, the preferred stock will have no preemptive rights to subscribe for any additional securities which are issued by us, meaning, the holders of shares of preferred stock will have no right to buy any portion of the issued securities.

In addition, unless the applicable prospectus supplement indicates otherwise, we will have the right to “reopen” a previous issue of a series of preferred stock by issuing additional preferred stock of such series.

The transfer agent, registrar, dividend disbursing agent, calculation agent and redemption agent for shares of each series of preferred stock will be named in the prospectus supplement relating to such series.

Dividends

The holders of the preferred stock of each series will be entitled to receive cash dividends out of funds legally available, when, as and if, declared by our board of directors or a duly authorized committee of the board, at the rates and on the dates stated in the applicable prospectus supplement. These rates may be fixed, or variable, or both. If the dividend rate is variable, the applicable prospectus supplement will describe the formula used to determine the dividend rate for each dividend period. We will pay dividends to the holders of record as they appear on our stock books on the record dates determined by our board of directors or an authorized committee of our board.


Voting Rights

Holders of shares of preferred stock will have no voting rights, except as (i) otherwise stated in the applicable prospectus supplement, (ii) as otherwise stated in the certificate of designations establishing such series or (iii) as required by applicable law.

Redemption

A series of the preferred stock may be redeemable, in whole or in part, at our option, and may be subject to mandatory redemption under a sinking fund or otherwise as described in the applicable prospectus supplement. If a series of preferred stock is redeemable at our option, that applicable prospectus supplement will specify the conditions to such redemption and any restrictions, whether pursuant to the terms of the preferred stock or other securities or obligations of our, or pursuant to regulatory requirements, on our ability to redeem. If a series of preferred stock is subject to mandatory redemption, the applicable prospectus supplement will specify the number of shares that we will redeem, the time or times for such redemption, the redemption price per share and other obligations of ours in connection with the redemption. In each case, the applicable prospectus supplement will indicate whether the redemption price can be paid in cash or other property. Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of such shares will terminate except for the right to receive the redemption price.

Conversion and Exchange

If any series of preferred stock we propose to offer and issue is convertible into or exchangeable for any other class or series of our capital stock or any other securities of ours, the applicable prospectus supplement relating to that series will describe the terms and conditions governing the conversions and exchanges.

Liquidation Rights

If we voluntarily or involuntarily liquidate, dissolve or wind up our business, the holders of shares of each series of preferred stock and any other securities that have rights equal to that series of preferred stock under these circumstances, will be entitled to receive out of our assets that are available for distribution to stockholders a distribution in the amount provided in certificate of designations and will receive such distributions (if any) before any distribution to holders of common stock or of any securities ranking junior to the series of preferred stock. If our assets are insufficient to pay all amounts to which holders of preferred stock are entitled, we will make no distribution on the preferred stock or on any other securities ranking equal to the preferred stock unless we make a pro rata distribution to those holders. After we pay the full amount of the liquidation distribution to which the holders are entitled, the holders will have no right or claim to any of our remaining assets.

Unless otherwise stated in the applicable prospectus supplement or the certificate of designations, neither the sale of all or any part of our property and business, nor our merger into or consolidation with any other corporation, nor the merger or consolidation of any other corporation with or into us, will be deemed to be a dissolution, liquidation or winding up.

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the warrants that we may offer under this prospectus, and the related warrant agreements and warrant certificates. While the terms summarized below will apply generally to any warrants that we may offer, we will describe the particular terms of any warrants in more detail in the applicable prospectus supplement.

Exercise of Warrants

Each warrant will entitle the holder to purchase such shares of common stock or preferred stock, as the case may be, at such exercise price as shall in each case be set forth in, or calculable from, the prospectus supplement relating to the warrants we propose to offer and issue.

While the terms summarized below will apply generally to any units that we may offer, we will describe the particular terms of any units in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any units offered under that prospectus supplement may differ from the terms described below. Specific unit agreements and/or unit certificates will contain additional important terms and provisions and will be incorporated by reference as an exhibit to the registration statement that includes this prospectus. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the unit agreement and/or unit certificate that contains the specific terms of the units we offer for sale.

We may issue units comprised of two or more of the other securities described in this prospectus in any combination and in one or more series. We may evidence each series of units by unit certificates that we will issue under a separate agreement. We may enter into unit agreements with a unit agent. Each unit agent will be a bank or trust company that we select. We will indicate the name and address of the unit agent, if any. in the applicable prospectus supplement relating to a particular series of units.

PLAN OF DISTRIBUTION

We may sell the securities being offered hereby in one or more of the following ways from time to time:

to underwriters for resale to the public or to investors;

through agents to the public or to investors; 

in “at the market” offerings, within the meaning of Rule 415(a)(4) of the Securities Act, to or through a market maker or into an existing trading market on an exchange or otherwise;

through dealers; 

directly to investors; or 

through a combination of any of these methods or any other method permitted by law.

We may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. In the prospectus supplement relating to such offering, we will name any agent that could be viewed as an underwriter under the Securities Act and describe any commissions that we are obligated to pay to any such agent. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis.

This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

Each time that we use this prospectus to sell our securities, we will provide a prospectus supplement that describes the method of distribution of the securities and will set forth the specific terms of the offering of securities, including, as applicable:

the terms of the offering;
the name or names of any underwriter, dealer or agent;
the public offering or purchase price of the securities and the proceeds we will receive from the sale;
any discounts and commissions to be allowed or paid to the underwriter or agent;
all other items constituting underwriting compensation;
any discounts and commissions to be allowed or reallowed or paid to dealers;
any over-allotment option we grant to the underwriter under which the underwriter may purchase additional securities from us; and
any securities exchanges on which the securities will be listed.

If an underwriter is utilized in the sale of the securities being offered by this prospectus or any prospectus supplement, an underwriting agreement will be executed under which the underwriter will make resales of the securities to the public. In connection with the sale of the securities, we or the purchasers of securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriter and/or commissions from the purchasers for which they may act as agent. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis. If a dealer is utilized in the sale of the securities being offered by this prospectus or any prospectus supplement, the securities will be sold to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.


Any compensation paid to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers will be provided in the applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. In addition, we may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any resales thereof.

We may enter into agreements to indemnify underwriters, agents and dealers against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof and to reimburse those persons for certain expenses.

Certain underwriters, agents and dealers, and their associates and affiliates, may be customers of, have borrowing relationships with, engage in other transactions with, or perform services, including investment banking services, for us or one or more of our respective affiliates in the ordinary course of business.

The sale and distribution of the securities may be effected from time to time in one or more transactions:

at a fixed price or prices, which may be changed;
at market prices prevailing at the time of sale;
at prices related to such prevailing market prices; or
at negotiated prices.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may over allot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. In any offering of the securities through a syndicate of underwriters, the underwriting syndicate also may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these provisions whichactivities may have the effect of delayingstabilize or preventing a change in control of the Company could have a material adverse effect on the market value of the Company's Common Stock. Dividends Unlikely The Company intends to retain its earnings to finance the growth of its business and therefore does not intend to pay dividends on its Common Stock in the foreseeable future. Potential Volatility of Stock Price Factors such as announcements of technological innovations or new products by the Company, its competitors or third parties, quarterly variations in the Company's actual or anticipated results of operations, failure of revenues or earnings in any quarter to meet the investment community's expectations, and market conditions for emerging growth stocks 8 or cable industry stocks in general may causemaintain the market price of the Company's Common Stocksecurities above independent market levels. Any such underwriters are not required to fluctuate significantly. The stock priceengage in these activities and may also be affected by broader market trends unrelated to the Company's performance. These fluctuationsend any of these activities at any time.

We may adversely affectengage in at the market price of the Company's Common Stock. Risk of Labor Negotiations All of the Company's direct labor employees are members of the International Brotherhood of Electrical Workers Union, Local 2066, under a collective bargaining agreement which expiresofferings into an existing trading market in February, 1999. Delays or difficulties in negotiating and executing a new agreement, which may result in work stoppages, could have a material adverse effect on the Company's results of operations and financial condition. Shares Eligible for Future Sale; Possible Adverse Effect on Market Price Sales of a substantial number of shares of Common Stock in the public market after this offering could adversely affect the market price of the Common Stock and could impair the Company's future ability to raise capital through an offering of its equity securities. Each of the Company's principal stockholders holds a significant portion of the Company's outstanding Common Stock, and a decision by one or more of these stockholders to sell a significant portion of his shares could adversely affect the market price of the Common Stock. Following the offering, an additional 317,889 shares will be immediately available for resale in the public market without restriction, unless such shares are held by "affiliates" of the Company, as that term is defined inaccordance with Rule 144415(a)(4) under the Securities Act. USEIn addition, we may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be named in the applicable prospectus supplement or a post-effective amendment. In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus and an applicable prospectus supplement. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

Any underwriters who purchase securities from us for public offering and sale may make a market in those securities, but these underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot assure you that there will be a trading market for any securities, and, if a trading market for any securities does develop, we cannot assure you that such market will be liquid.

The specific terms of any lock-up provisions in respect of any given offering will be described in the applicable prospectus supplement.


LEGAL MATTERS

Blonder Tongue Laboratories, Inc.

Blonder Tongue was incorporated in November 1988, under the laws of Delaware as GPS Acquisition Corp. for the purpose of acquiring the business of Blonder-Tongue Laboratories, Inc., a New Jersey corporation, which was founded in 1950 by Ben H. Tongue and Isaac S. Blonder to design, manufacture and supply a line of electronics and systems equipment principally for the private cable industry. Following the acquisition, we changed our name to Blonder Tongue Laboratories, Inc. Blonder Tongue completed the initial public offering of its shares of common stock in December 1995.

Today, Blonder Tongue is a technology research and development (“R&D”) company with U.S.-based manufacturing, that delivers a wide range of products and services to major telecommunications, cable and fiber optic service delivery operators, as well as broadcasters and media production companies. For over 70 years, our products have provided the latest technology for telecom company Central Offices (COs), cable operator headends, broadcaster studios (together “Telecom”), as well as to lodging/hospitality, multi-dwelling units/apartments (“MDU”) and a range of business to business (“B-B”) customers at a wide range of locations including university campuses, healthcare/hospitals, fitness centers, government facilities, military bases, prisons, airports, sports stadiums/arenas, entertainment venues/casinos, retail stores, and smallmedium businesses. These applications are also variously described as commercial, institutional, and/or enterprise environments and will be referred to herein collectively as “CIE.” The customers we serve also include business entities distributing and installing private data delivery, broadband and video networks in these environments, including the world’s largest cable television operators, telecommunications providers and satellite providers, as well as integrators, architects, engineers or the next generation of Internet Protocol Television (“IPTV”) streaming video service providers.

We continue to be focused on the needs of an expanding group of customers, providing high quality, ultra-high reliability technology products to meet their needs and supporting those products following deployment. For over 70 years we have provided innovative solutions based on continually advancing technology. Since our founding, Blonder Tongue has continued to keep abreast of evolving technologies, from analog to digital television, Hybrid-Fiber Coax (“HFC”) networks with Quadrature Amplitude Modulation (“QAM”) edge devices, High Definition (“HD”) and Ultra HD (“4K”) and (“UHD”) encoding and transcoding, IPTV processing and distribution, multiscreen Adaptive Bit Rate (“ABR”) technologies and high-speed data delivery technologies.

Beginning in January 2020, Blonder Tongue has been implementing a strategic plan to improve operating results towards increasing shareholder value. This plan consists of:

oAdapting operating expenses in line with expected revenue and income levels.

oFocusing R&D on short-term high confidence opportunities with compelling ROI.

oExpanding sales and marketing efforts directly to service operators.

oStreamlining manufacturing operations and simplifying product offerings.

oIncreasing gross margins.

In 2019, Blonder Tongue initiated a consumer premise equipment (“CPE”) sales initiative. The products sold in 2019 comprise primarily Android-based IPTV set top boxes targeted to the Tier 2 and Tier 3 telecommunications and fiber optics-based service providers. Total CPE product sales, including product accessories and replacement parts, were $4,165,000 in 2020 and $3,977,000 in 2019.


Like many businesses throughout the United States and the world, we have been affected by the COVID-19 outbreak. Because there are daily developments regarding the outbreak, we are continually assessing the current and anticipated future effects on our business, including how these developments are impacting or may impact our customers, employees and business partners. In our core CIE business, we have experienced a noticeable decline in sales, as many of our customers have significantly reduced their business operations. In our CPE business we have experienced a more substantial reduction in sales, again as a result of our customers’ significant decrease in their business activities. With uncertainties surrounding the extent to which the COVID-19 outbreak will affect the economy generally, and our customers and business partners in particular, it is impossible for us to predict when conditions will improve to the point that we can reasonably forecast when our sales might return to historical levels. However, we are currently taking steps to significantly reduce our expenses, including adjustments in our staffing (in the form of furloughs) and reductions in manufacturing activities, which we believe will improve our ability to continue our operations at current levels and meet our obligations to our customers.

Our manufacturing is allocated primarily between its facility in Old Bridge, New Jersey (“Old Bridge Facility”) and key contract manufacturing located in the People’s Republic of China (“PRC”) as well as South Korea, Taiwan and Ohio. We currently manufacture most of our digital products, including the NXG product line and latest encoder, transcoder and EdgeQAM collections at the Old Bridge Facility. Since 2007 we have transitioned and continue to manufacture certain high volume, labor intensive products, including many of our analog and other products, in the PRC, pursuant to manufacturing agreements that govern the production of products that may from time to time be the subject of purchase orders submitted by (and in the discretion of) Blonder Tongue. Although we do not currently anticipate the transfer of any additional products to the PRC or other countries for manufacture, we may do so if business and market conditions make it advantageous to do so. Manufacturing products both at the Old Bridge Facility as well as in the PRC, South Korea, Taiwan and Ohio enables Blonder Tongue to realize cost reductions while maintaining a competitive position and time-to-market advantage.

The Company may, from time to time, provide manufacturing, research and development and product support services for other companies’ products. In 2015, the Company entered into an agreement with VBrick Systems, Inc. (“VBrick”) to provide procurement, manufacturing, warehousing and fulfillment support to VBrick for a line of high-end encoder products and sub-assemblies. Sales to VBrick of encoder products were approximately $145,000 and $602,000 in 2020 and 2019, respectively. Sales to VBrick for sub-assemblies were not material in 2020 or 2019.

DESCRIPTION OF SECURITIES

The following description summarizes the material terms of the common stock that may be offered and sold by the selling securityholders under this prospectus. The following description provides a summary of the terms of our common stock, but does not purport to be complete and is subject to and qualified by reference to our certificate of incorporation and bylaws, as amended to date, which have been filed with or incorporated by reference in the registration statement of which this prospectus is a part.

The description below does not contain all of the information that you might find useful or that might be important to you. You should refer to the provisions of our certificate of incorporation and bylaws because they, and not the summaries, define the rights of holders of shares of our common stock. These documents are available as described under the heading “Where You Can Find More Information.”

General

Our certificate of incorporation authorizes the issuance of up to 25,000,000 shares of common stock and 5,000,000 shares of preferred stock. The rights and preferences of the preferred stock may be established from time to time by our board of directors. As of April 16, 2021, there were 11,960,505 shares of common stock issued and outstanding and no shares of preferred stock issued and outstanding.

Voting Rights

Except as otherwise required by law and except as provided by the terms of any other class or series of stock, holders of common stock have the exclusive power to vote on all matters presented to our stockholders, including the election of directors. Each holder of common stock is entitled to one vote per share, and each holder does not have cumulative voting rights. Accordingly, the holders of a majority of the shares of common stock entitled to vote in any election of directors can elect all of the directors standing for election if they so choose. All matters are decided by the vote of a majority in voting interest of the stockholders present in person or by proxy and voting at any meeting of the stockholders during which a quorum is present, except as otherwise provided in our certificate of incorporation, our bylaws or by applicable law.

Because our certificate of incorporation permits our board of directors to set the voting rights of preferred stock, it is possible that holders of one or more series of preferred stock issued in the future could have voting rights that might limit the effect of the voting rights of holders of common stock.

Dividend Rights; Liquidation Rights

Subject to preferences that may be applicable to any then outstanding preferred stock, holders of common stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by the board of directors out of legally available funds. In addition, we may be party to one or more agreements, such as loan agreements and credit facilities, that will contractually limit our ability to pay dividends.

Because our certificate of incorporation permit our board of directors to set the dividend rights of preferred shares, it is possible that holders of one or more series of preferred shares issued in the future could have dividend rights that differ from those of the holders of our common stock. If the holders of a class or series of preferred stock is given dividend rights, the right of holders of preferred shares to receive dividends could have priority over the right of holders of our common stock to receive dividends.

We have followed and presently intend to continue following a policy of retaining earnings, if any. We have not historically declared or paid dividends on our common stock, and we do not expect to do so in the foreseeable future. Any future determination relating to our dividend policy will be made at the discretion of our board of directors and will depend on a number of factors, including our earnings and financial condition, liquidity and capital requirements, the general economic and regulatory climate, our ability to service any equity or debt obligations senior to our common stock, and other factors deemed relevant by our board of directors.


In the event of our liquidation, dissolution or winding up, holders of common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any outstanding shares of preferred stock.

Redemption, Preemptive Rights and Repurchase Provisions

Holders of common stock have no preemptive or conversion rights or other subscription rights, and there are no redemption, repurchase or sinking fund provisions applicable to the common stock. Discretionary repurchases of our common stock may be subject to contractual prohibitions or limitations, including prohibitions or limitations included in loan agreements and credit facilities.

Potential Effects of Issuance of Preferred Stock

Under the terms of our certificate of incorporation, the board of directors is authorized, subject to any limitations prescribed by law, without stockholder approval, to issue shares of preferred stock in one or more series. Each such series of preferred stock will have such rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, as shall be determined by the board of directors.

The purpose of authorizing the board of directors to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing desirable flexibility in connection with a variety of corporate purposes, could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of our outstanding voting stock.

The effects of issuing preferred stock could include one or more of the following:

decreasing the amount of earnings and assets available for distribution to holders of common stock; 
restricting dividends on the common stock;
diluting the voting power of the common stock;
impairing the liquidation rights of the common stock; or
delaying, deferring or preventing changes in our control or management.

Effect of Certain Provisions of our Certificate of Incorporation and Bylaws and the Delaware Anti-Takeover Statute

Some provisions of Delaware law and our certificate of incorporation and bylaws could make the following transactions more difficult:

acquisition of us by means of a non-negotiated tender offer or similar transaction; 
a change of control by means of a proxy contest or other; or 
removal of our incumbent directors.

It is possible that these provisions could make it more difficult to accomplish or could deter transactions that shareholders may otherwise consider to be in their best interest or in our best interest, including transactions which provide for payment of a premium over the market price for our shares.

These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of the increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms. 


Provisions of Our Governing Documents. Our certificate of incorporation and bylaws include provisions that may have the effects summarized above. These provisions:

empower our board of directors, without stockholder approval, to issue preferred stock, the terms of which, including voting power, are set by our board of directors; 
divide our board of directors into three classes serving staggered three-year terms; 
restrict the ability of stockholders to remove directors; 
prohibit action by the stockholders without a stockholder meeting; 
eliminate cumulative voting in elections of directors; 
require that shares representing at least two-thirds of the total voting power approve any amendment to or repeal of our bylaws; 
require advance notice of nominations for the election of directors and the presentation of stockholder proposals at meetings of stockholders; and 
allow the board of directors to increase or decrease the number of directors.

Provisions of Applicable Law – Delaware Anti-Takeover Statute. We are subject to Section 203 of the Delaware General Corporation Law (“DGCL”). This law prohibits a publicly held Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an “interested stockholder” unless:

prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; 
upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned by persons who are directors and also officers and by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or 
on or subsequent to the date of the transaction, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.

Section 203 defines “business combination” to include:

any merger or consolidation involving the corporation and the interested stockholder;
any sale, transfer, pledge or other disposition of 10% or more of our assets involving the interested stockholder;


in general, any transaction that results in the issuance or transfer by us of any of our stock to the interested stockholder; or 
the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 of the DGCL defines an “interested stockholder” as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

Limitation of Liability and Indemnification

Section 145 of the DGCL allows us to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was our director, officer, employee or agent, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to our best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. Section 145 further allows us to indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in our favor, by reason of the fact that the person is or was our director, officer, employee or agent, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to our best interests and except that no indemnification is permitted in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to us, unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought determines that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court deems proper.

Section 102(b)(7) of the DGCL permits us to include in our certificate of incorporation a provision eliminating or limiting the personal liability of a director to us or our stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to unlawful payment of dividends and unlawful stock purchase and redemption) or (iv) for any transaction from which the director derived an improper personal benefit.

Our certificate of incorporation provides that our directors shall not be liable to Blonder Tongue or our stockholders for monetary damages for breach of fiduciary duty as a director except to the extent that exculpation from liabilities is not permitted under the DGCL as in effect at the time such liability is determined. In addition, our certificate of incorporation and our bylaws each include provisions requiring us to indemnify directors and officers to the fullest extent permitted by the DGCL. Our certificate of incorporation and bylaws provide that any person made a party or threatened to be made a party to a threatened, pending or completed action, suit or proceeding by reason of the fact that such person is or was a director or officer of ours, is or was serving at our request as a director or officer of another corporation or enterprise, including service with respect to an employee benefit plan, shall be indemnified by us against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding to the fullest extent authorized from time to time by the DGCL. The rights of indemnification are not exclusive of any other rights to which those seeking indemnification may be entitled and shall continue as to a person who ceases to be a director, officer, employee or agent.


We have obtained director and officer liability insurance under which, subject to the limitations of such policies, coverage will be provided (a) to directors and officers against loss arising from claims made by reason of breach of fiduciary duty or other wrongful acts as a director or officer, including claims relating to public securities matters and (b) to us with respect to payments which we may make to our directors and officers pursuant to the indemnification provisions summarized above or otherwise as a matter of law.

We also have entered into indemnification agreements with our directors and officers. The indemnification agreements provide directors and officers with further indemnification to the maximum extent permitted by the DGCL.

We believe that the foregoing policies and provisions of our governing documents are necessary to attract and retain qualified officers and directors. Insofar as indemnification for liabilities arising under the Securities Act may be permitted with respect to our directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Section 145 further provides that a corporation similarly may indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor, by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall notbe made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Companycorporation unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court shall deem proper.

Section 102(b)(7) of the DGCL permits a corporation to include in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a Director.

II-1

The effect of the provision of the Company'sregistrant’s Restated Certificate of Incorporation isprovides that the registrant’s directors shall not be liable to eliminate the rights ofregistrant or the Company and itsregistrant’s stockholders (through stockholders' derivative suits on behalf of the Company) to recoverfor monetary damages against a director for breach of the fiduciary duty of care as a director (including breaches resultingexcept to the extent that exculpation from negligent or grossly negligent behavior) exceptliabilities is not permitted under the DGCL as in effect at the situations described in clauses (i) through (iv) above. This provision does not limit or eliminatetime such liability is determined. The registrant’s Restated Certificate of Incorporation and Amended and Restated Bylaws each also include provisions requiring the rights of the Company or any stockholderregistrant to seek nonmonetary relief such as a injunction or rescission in the event of a breach of a director's duty of care.
