The actual number of shares of Common Stock into which the Class A Warrant is exercisable will depend upon whether the Company requires the holder of the Class A Warrant to exercise all of part of such Class A Warrant and will also depend upon future market conditions. If the Company required the holder of the Class A Warrant to fully exercise such warrant, based upon current market conditions, as of September 30, 1998, the Class A Warrant being registered hereunder would be exercisable into approximately [2,248,876] shares of Common Stock. In accordance with Rule 416 under the Securities Act of 1933, Common Stock offered hereby shall also be deemed to cover an indeterminate number of securities to be offered or issued to prevent dilution resulting from stock splits, stock dividends or similar transactions, as well as an indeterminate number of shares of Common Stock issuable upon exercise of the Class A Warrant, and is deemed to include any additional shares of Common Stock that may be issuable upon such exercise as a result of the antidilution provisions thereof or as a result of any adjustment to the exercise price. The Registrant hereby amends this Registration Statement on such date or dates as may be necessary to delay its effective date until the Registrant shall file a further amendment which specifically states that this Registration Statement shall thereafter become effective in accordance with Section 8(a) of the Securities Act of 1933 or until the Registration Statement shall become effective on such date as the Commission, acting pursuant to said Section 8(a), may determine. PROSPECTUS RESEARCH FRONTIERS INCORPORATED COMMON STOCK ISSUABLE UPON EXERCISE OF CLASS A WARRANT AND CLASS B WARRANT (THE "WARRANTS") This Prospectus relates to the sale from time to time by the selling stockholder (the "Selling Stockholder") of an indeterminate number of shares of common stock, $0.0001 par value per share (the "Common Stock"), of Research Frontiers Incorporated, a Delaware corporation (the "Company") issuable upon exercise of a Class A Warrant and 131,000 shares of Common Stock warrants issuable ) issuable upon exercise of a Class B Warrant (collectively, the "Shares"). The actual number of shares of Common Stock into which the Class A Warrant is exercisable will depend upon whether the Company requires the holder of the Class A Warrant to exercise all of part of such Class A Warrant and will also depend upon future market conditions. If the Company requires the holder of the Class A Warrant to fully exercise such warrant, based upon current market conditions, as of the date of this Prospectus, such Class A Warrant would be exercisable into approximately [x,xxx,xxx] shares of Common Stock. It is anticipated that the Shares will be offered from time to time in brokerage transactions (which may include block transactions), in the over- the-counter market or negotiated transactions at prices and terms prevailing at the times of such sales, at prices related to such market prices or at negotiated prices. Such shares may be sold directly to purchasers, through broker-dealers acting as agents for the Selling Stockholder or to broker- dealers who may purchase the Selling Stockholder's Shares as principals and thereafter sell the Shares from time to time in the over-the-counter market, in negotiated transactions or otherwise, or by a combination of these methods. Broker-dealers who effect these transactions may receive compensation in the form of discounts or commissions from the Selling Stockholder or from the purchasers of the Shares for whom the broker- dealers may act as an agent or to whom they may sell as a principal, or both. See "Selling Stockholder" and "PLAN OF DISTRIBUTION". The Company may receive in the future the exercise price of the Warrants. The Company will not receive any proceeds from the sale of Common Stock by the Selling Stockholder. Broker-dealers, if any, acting in connection with such sales, might be deemed to be "underwriters" within the meaning of Section 2(11) of the Securities Act of 1933, as amended (the "Securities Act") and any commission received by them and any profit on the resale of such securities might be deemed to be underwriting discounts and commissions under the Securities Act. The Company has agreed to bear all of the expenses in connection with the registration and sale of the Shares (other than selling commissions and fees), estimated to be $50,000. The Company has also agreed to indemnify the Selling Stockholder against certain liabilities, including liabilities arising under the Securities Act. The Company's Common Stock trades on the Nasdaq National Market System under the symbol "REFR". On September 30, 1998 as reported by Nasdaq, the last sales price of a share of Common Stock was $6.9375. THE SECURITIES OFFERED BY THIS PROSPECTUS ARE SPECULATIVE AND INVOLVE A HIGH DEGREE OF RISK.

RISK FACTORS An investment in the securities described herein entails a number of significant risks. Because of these risks, funds should only be invested by persons who are able to bear the risk of and withstand the loss of their entire investment. Prospective investors should also consider the following before making an investment decision. History of Operating Losses and Accumulated Deficit. Since inception, the Company has been primarily engaged in research and development activities. To date, the Company's revenues have been insufficient to fund operating expenses, and operating losses can be expected for the foreseeable future. There can be no assurance the Company will ever be profitable, or that if additional funding is necessary to fund the Company's operations, that additional funding will be available when needed, or if available, that its terms will be favorable or acceptable to the Company. Need for Additional Funds. The Company has been dependent upon the proceeds of equity financings to fund operations. The Company expects to use its cash and the proceeds from maturities of its investments to fund its research and development of SPD (suspended particle device) light valves and for other working capital purposes. The Company's working capital and capital requirements depend upon numerous factors, including the results of research and development activities, competitive and technological developments, the timing and cost of patent filings, and the development of new licensees and changes in the Company's relationships with its existing licensees. The degree of dependence of the Company's working capital requirements on each of the foregoing factors cannot be quantified; increased research and development activities and related costs would increase such requirements; the addition of new licensees may provide additional working capital or working capital requirements, and changes in relationships with existing licensees would have a favorable or negative impact depending upon the nature of such changes. Based upon existing levels of expenditures, assumed ten percent annual increases therein, existing cash reserves and budgeted revenues, the Company believes that it would not require additional funding for at least the next three years. There can be no assurance that expenditures will not exceed the anticipated amounts or that additional financing, if required, will be available when needed or, if available, that its terms will be favorable or acceptable to the Company. Eventual success of the Company and generation of positive cash flow will be dependent upon the commercialization of products using the Company's technology by the Company's licensees and payments of continuing royalties on account thereof. Research and Development Company; Unproven Technology. The Company is subject to all of the risks inherent in the development of new technologies and products. There can be no assurance that the Company's future operations will generate significant revenues or be profitable. The likelihood of the Company's success must be considered in light of the problems, expenses and delays frequently encountered in the commercialization and marketing of new technologies and the competitive environment in which the Company operates. All Products Being Developed Depend on Viability of the Company's Light Valve Technology. All products being developed by the Company's licensees depend on the viability of the Company's light valve technology. No commercial products have yet been produced for sale. The Company has not developed any other technology. Thus, if commercially acceptable products cannot be developed from the Company's light valve technology, the Company will not be successful. Absence of Manufacturing and Marketing Capability. The Company's light valve technology is currently licensed to eight companies and is being evaluated by others for possible exploitation in various commercial applications. In the past, some entities have evaluated the Company's technology without proceeding to enter into further negotiations or agreements with the Company. The Company intends to continue to exploit its light valve technology by licensing it to manufacturers of end products and to one or more other companies to manufacture the Company's light-controlling films. The Company anticipates that its licensee(s) would have primary responsibility for marketing and manufacturing activities. There can be, however, no assurance that any definitive future agreements or arrangements will materialize. To date, neither the Company nor any of its licensees has produced a commercial product incorporating the Company's light valve technology. The Company cannot control the activities of its licensees. There can be no assurance as to when or whether the licensees will produce any commercial product using the Company's light valve technology or, if produced, that such product will become commercially viable. Dependence on Key Personnel. The success of the Company is dependent on, among other things, the services of its senior management, the loss of whose services could have a material adverse effect upon the prospects of the Company. Competition with Proven Technologies. The Company's light valve technology will compete with other light control and display technologies which are being commercially exploited with great success, such as LEDs, plasma displays, and LCDs. Companies with liquid crystal, electrochromic and possibly other technologies are now competing or probably will compete against the Company in the field of so-called "smart windows." In general, the companies which will compete against the Company have substantially greater financial, marketing, technical and other resources and name recognition than the Company. There can be no assurance that the Company's light valves (whose performance and long-term reliability have not yet been fully ascertained) will be able to displace other devices being used commercially or otherwise find a niche for commercial application. Technological Obsolescence. While the Company believes that its light valves will have certain advantages over some existing display devices, other types of so-called "smart windows" and photochromic eyeglasses, there can be no assurance that one or more of the numerous existing companies which manufacture or may manufacture such products, or any company formed after the date hereof, will not be able to develop products using alternative technologies that would render the Company's products difficult to market or technologically or otherwise obsolete. Uncertain Patent Protection. Although aspects of the Company's technology are covered by 19 United States patents, 3 pending patent applications in the United States, 32 foreign patents, and 59 foreign patent applications, a number of those patents cover earlier versions and features of the Company's light valves which the Company does not intend to exploit. Moreover, the issuance of a patent does not carry any certainty of successful application or commercial success. There can be no assurance that these patents will be upheld if the Company seeks to enforce its patent rights against an infringer or that the Company will have sufficient resources to prosecute its rights. The Company also relies, to a lesser extent, on trade secrets and confidential disclosure agreements to protect its technology. Neither the issuance of patents nor the use of trade secrets will necessarily protect the Company from other persons using technologies similar to those covered by the Company's patents or trade secrets. In addition, there can be no assurance that any particular aspect of the Company's technology will not be found to infringe the claims of other existing patents. No Cash Dividends. The Company has never paid any cash dividends and does not anticipate paying any cash dividends for the foreseeable future. Volatility of Stock Price. Since the initial public offering of the Company's securities in July 1986, the market for the Company's securities has been volatile. The trading price of the Company's securities may continue to fluctuate significantly based on, among other things, announcements by the Company and its competitors and price and volume fluctuations relating to high-technology companies generally. No Use of Proceeds. The Company will not receive any proceeds from the sale of Common Stock by the Selling Stockholder. The Company will only receive the aggregate exercise price of the Warrants if such Warrants are exercised by the Selling Stockholder. Such exercise may depend upon whether the Company requires the Selling Stockholder to exercise all of part of the Class A Warrant issued to it, and will also depend upon future market conditions. Authorization of Additional Securities. The Company is authorized to issue 100,000,000 shares of Common Stock. As of the date of this Prospectus, there were [11,007,468] shares of Common Stock issued and outstanding. The Company's Board of Directors has the power to issue any and all unissued shares without stockholder approval. To the extent that additional shares of Common Stock are issued, dilution to the interests of the Company's stockholders will occur. See "DESCRIPTION OF SECURITIES." THE COMPANY General Research Frontiers Incorporated (the "Company") was incorporated in New York in 1965 and reincorporated in Delaware in 1989. Since its inception, the Company has primarily engaged in the development and licensing of suspended particle technology and devices to control the transmission of light. Such suspended particle devices, often referred to as "SPDs" or "light valves" use a suspension of microscopic particles that is either in the form of a liquid suspension or a film, which is usually enclosed between two conductively-coated glass or plastic plates, at least one of which is transparent. When an electrical voltage is applied, the microscopic particles are aligned, thereby permitting a range of transparency within which light transmission can be rapidly varied to any degree desired depending upon the voltage applied. The first light valve of this type was invented by Dr. Edwin Land of Polaroid Corporation in 1934. Since its incorporation the Company has developed its own technology embodied in patents, trade secrets and know- how. Light valves using the Company's proprietary suspensions and related technology may have wide commercial applications in devices of many types where variable light transmission is desired, such as "smart" windows, variable light transmission eyewear such as goggles and sunglasses, self-dimmable automotive sunroofs, sun visors and mirrors, and flat panel information displays for use in computers, televisions, telephones and other electronic instruments. DIVIDENDS The Company has never paid any cash dividends and does not anticipate paying any cash dividends for the foreseeable future. USE OF PROCEEDS The Company will not receive any proceeds from the sale of Common Stock by the Selling Stockholder. The Company will only receive the aggregate exercise price of the Warrants if such Warrants are exercised by the Selling Stockholder. Such exercise may depend upon whether the Company requires the Selling Stockholder to exercise all of part of the Class A Warrant issued to it, and will also depend upon future market conditions. The Company expects that any net proceeds from the exercise of the Warrants will be used for research and development, working capital, acquisitions, and for general corporate purposes, in such amounts as the Company, in its discretion, deems appropriate. Pending utilization, the Company intends to invest such funds in money market funds and other interest-bearing obligations. Selling Stockholder The following table sets forth certain information regarding beneficial ownership of the Company's Common Stock as of the date of this Prospectus, adjusted to reflect the sale of the Common Stock by the Selling Stockholder. The Selling Stockholder named in the table has sole voting and investment power with respect to all Common Stock shown as beneficially owned by it. The information given assumes that all Common Stock received upon exercise of the Warrants described herein which are held by the Selling Stockholder are sold. The Common Stock offered by the Selling Stockholder may be offered for sale from time to time at market prices prevailing at the time of sale or at negotiated prices, and without payment of any underwriting discounts or commissions except for usual and customary selling commissions paid to brokers or dealers. The Selling Stockholder may sell all, a part, or none of the number of shares of Common Stock offered by this Prospectus. The Selling Stockholder has not held any position, office or other material relationship with the Company (or had any such position, office or material relationship within the past three (3) years). Because the number of Shares into which the Class A Warrant are exercisable into depends upon whether the Company requires the Selling Stockholder to exercise all of part of the Class A Warrant issued to it, and will also depend upon the market price of the Company's common stock from time to time, it is not possible to calculate the number of shares of Common Stock which will be ultimately issued upon exercise of the Class A Warrant. Therefore, the aggregate exercise price of the Class A Warrant subscribed for by the Selling Stockholder is listed below in place of the number of shares beneficially owned by such Selling Stockholder prior to this offering and in place of the number of Shares offered by such Selling Stockholder. Because of this, it is not possible to calculate the percentage of the Company's outstanding Common Stock beneficially owned by the Selling Stockholder. Under the terms of the Class A Warrant, the total number of shares of Common Stock of the Company deemed beneficially owned by the Selling Stockholder, together with all shares of the common stock of the Company deemed beneficially owned by the Selling Stockholder's "affiliates" as defined in Rule 144 of the Securities Act of 1933, as amended, may never exceed 4.9% of the total issued and outstanding shares of the Common Stock of the Company. Aggregate Warrant Shares Beneficially Exercise Price ($) or Owned After Offering Number of Shares Under- by Selling Stockholder Beneficial Owner lying Class B Warrant Number % Ailouros Ltd. (Class A Warrant) $15,000,000 0 0 Ailouros Ltd. (Class B Warrant) 131,000 0 0 DESCRIPTION OF SECURITIES Common Stock The Company is authorized to issue 100,000,000 shares of Common Stock, $0.0001 par value per share, of which [11,007,468] shares were outstanding as of the date of this Prospectus. On October 1, 1998, the Company sold the Class A Warrant and the Class B Warrant pursuant to a private placement to the Selling Stockholder which is an accredited investor. The Company is obligated to register the issuance of all shares of Common Stock issuable upon exercise of the Warrants. Under the terms of their agreement with the Company, at no time will a Selling Stockholder and their affiliates own in excess of 4.9% of the total issued and outstanding shares of the Common Stock. The Class A Warrant, which expires on December 31, 2001, entitles the Selling Stockholder to purchase from the Company at the Exercise Price a certain number of Shares based upon an amount set by the Company from time to time over the life of the Class A Warrant. Before the beginning of each of a series of three-month periods specified by the Company, the Company determines the amount of Common Stock that the Company wishes to issue to the Selling Stockholder during such three month period. The Company also sets the minimum or "floor" price per share at which such Common Stock is to be issued. The amount of Common Stock and the floor price can be reset by the Company in its sole discretion prior to the beginning of any such three month period. Therefore, at the beginning of each three month period , it is within the Company's control the aggregate amount of Common Stock to be issued pursuant to the Class A Warrant (which can range from $0 to $1.5 million during such three month period), and the minimum price per Share for such issuance. The Company may also choose not to issue any shares of Common Stock pursuant to the Class A Warrant. If the Company does decide to require the Selling Stockholder to purchase the amount specified by the Company, the Selling Stockholder may then exercise the Class A Warrant during such three month period into the number of Shares which equals the amount specified by the Company divided by the applicable Exercise Price. On a date or dates during such three month period in which the Selling Stockholder wishes to exercise all or part of the Class A Warrant, the Selling Stockholder is required to send a Notice of Exercise to the Company. The "Exercise Price" per share shall mean the lesser of (i) $15.00 or (ii) 92% of the average of the high and low trading prices on the Nasdaq National Market (or other exchange or market if the Shares are traded thereon) for each of the seven trading days preceding the date that a Notice of Exercise is given. The Exercise Price in effect during any three month period specified by the Company may never be lower than the floor price specified by the Company prior to the beginning of such three month period, and the Selling Stockholder's obligation to exercise the Class A Warrant during such three month period shall be suspended for so long as the Exercise Price is lower than the floor price specified by the Company. Unless otherwise agreed to by the Company and the Selling Stockholder, no more than $15 million may be raised by the Company pursuant to the exercise of the Class A Warrant. Because the number of Shares into which the Class A Warrant are exercisable into depends upon whether the Company requires the Selling Stockholder to exercise all of part of the Class A Warrant issued to it, and will also depend upon the market price of the Company's common stock from time to time, it is not possible to calculate the number of shares of Common Stock which will be ultimately issued upon exercise of the Class A Warrant. The Class B Warrant is initially exercisable into 65,500 Shares. If the Company has not sent the Selling Stockholder at least three Put Notices (as that term is defined in the Class A Warrant) by December 31, 2001, under certain circumstances the Class B Warrant will be exercisable into an additional 65,500 Shares. The Class B Warrant expires on September 30, 2008. The exercise price per Share of the Class B Warrant is $8.25 which represents 120% of average of the closing bid and ask price on the closing date on the date of the Class B Warrant's issuance. Holders of Common Stock are entitled (i) to receive ratable dividends from funds legally available for distribution when and if declared by the board of directors; (ii) to share ratably in all of the Company's assets available for distribution upon liquidation, dissolution or winding up of the Company; and (iii) to one vote for each share held of record on each matter submitted to a vote of stockholders. All outstanding shares of Common Stock are fully paid for and non-assessable. Holders of Common Stock do not have cumulative voting rights; therefore, a minority stockholder may be less able to gain representation on the Board of Directors of the Company. The Common Stock has no preemptive or similar rights. PLAN OF DISTRIBUTION The Selling Stockholder is entitled to distribute from time to time the Common Stock issuable upon exercise of the Warrants. Based upon current market conditions, as of the date of this Prospectus, the outstanding Warrants would be exercisable for an aggregate exercise price of $16,080,000 into approximately [x,xxx,xxx] shares of Common Stock, representing approximately [x.x%] of the issued and outstanding Common Stock of the Company after taking into account the issuance of such Common Stock upon exercise of the Warrants. The Company will not receive any proceeds from the sale of Common Stock by the Selling Stockholder. The Company will only receive the aggregate exercise price of the Warrants if such Warrants are exercised by the Selling Stockholder. Such exercise may depend upon whether the Company requires the Selling Stockholder to exercise all of part of the Class A Warrant issued to it, and will also depend upon future market conditions. The distribution of the Common Stock by the Selling Stockholder may be effected from time to time in one or more transactions (which may involve block transactions) on NASDAQ, on any exchange on which the Common Stock may then be listed, in the over-the-counter market, in negotiated transactions, through the writing of options on shares, or a combination of such methods of sale, at market prices prevailing prices or at negotiated prices. The Selling Stockholder may effect such transactions by selling shares to or through broker-dealers, and such broker-dealers may receive compensation in the form of underwriting discounts, concessions or commissions from the Selling Stockholder and/or purchasers of Common Stock for whom they may act as agent (which compensation may be in excess of customary commissions). Participating brokers and dealers may be deemed to be "underwriters" within the meaning of the Securities Act, and any commissions received by them and any profit on the resale of the Common Stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. To comply with certain states' securities laws, if applicable, the Common Stock will not be offered or sold in a particular state unless the Common Stock has been registered or qualified for sale in such state or an exemption from registration or qualification is available and complied with.

PART II INFORMATION NOT REQUIRED IN THE PROSPECTUS Item 13. Disclosure of Commission Position on Indemnification for Securities Act Liabilities. As described in Item 15, the Certificate of Incorporation of the Company provide for the indemnification of certain persons. Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the "Act") may be permitted to directors, officers and controlling persons of the registrant pursuant to the Certificate of Incorporation or By-Laws of the Company, or otherwise, the registrant has been informed that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. Item 14. Other Expenses of Issuance and Distribution. Estimated expenses relating to the distribution of the Common Stock registered herein are set forth below. Such expenses will be paid by the Company.

Item 15. Indemnification of Directors and Officers. Article EIGHTH of the Company's Certificate of Incorporation provides for the indemnification of the Company's officers and directors to the fullest extent permitted by Section 145 of the Delaware General Corporation Law (the "GCL"). Section 145 of the GCL provides as follows: 145 Indemnification of Officers, Directors, Employees and Agents; Insurance (a) A corporation may 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, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he 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), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful. (b) A corporation may indemnify any person 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 he 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 him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the 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 Court of Chancery or such other court shall deem proper. (c) To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) of this section, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith. (d) Any indemnification under subsections (a) and (b) of this section (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in subsections (a) and (b) of this section. Such determination shall be made (1) by the board of directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (3) by the stockholders. (e) Expenses (including attorneys' fees) incurred by an officer or director in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the corporation as authorized in this section. Such expenses (including attorneys' fees) incurred by other employees and agents may be so paid upon such terms and conditions, if any, as the board of directors deems appropriate. (f) The indemnification and advancement of expenses provided by, or granted pursuant to, the other subsections of this section shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office. (g) A corporation shall have power to purchase and maintain insurance on behalf of any person who 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 any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify him against such liability under this section. (h) For purposes of this section, references to "the corporation" shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this section with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued. (i) For purposes of this section references to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a person with respect to any employee benefit plan; and references to "serving at the request of the corporation" shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by, such director, officer, employee, or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interests of the corporation" as referred to in this section. (j) The indemnification and advancement of expenses provided by, or granted pursuant to, this section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person. Article NINTH of the Company's Certificate of Incorporation provides for the elimination of any personal liability for monetary damages of directors to the Corporation or its stockholders for breach of fiduciary duty, for negligence or for taking or omitting to take any action to the fullest extent permitted by Section 102(b) (7) of the GCL. Section 102(b) (7) of the GCL provides as follows: (b) In addition to the matters required to be set forth in the certificate of incorporation by subsection (a) of this section, the certificate of incorporation may also contain any or all of the following matters: (7) 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, 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 to the corporation or its stockholders, (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 this Title or (iv) for any transaction from which the director derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision becomes effective. All references in this subsection to a director shall also be deemed to refer to a member of the governing body of a corporation which is not authorized to issue capital stock. Item 16.

EXHIBIT 4.1 RESEARCH FRONTIERS INCORPORATED SUBSCRIPTION AGREEMENT October 1, 1998 Research Frontiers Incorporated 240 Crossways Park Drive Woodbury, New York 11797-2033 Attention: Robert L. Saxe, President Gentlemen: This Subscription Agreement is made by and between Research Frontiers Incorporated, a Delaware corporation (the "Company"), and the undersigned (the "Subscriber"), in connection with the offering (the "Offering") of certain warrants to purchase shares of common stock of the Company, $.0001 par value per share (the "Shares") pursuant to Regulation D ("Regulation D") promulgated under the Securities Act of 1933, as amended (the "Securities Act"). A. Subscription 1. Subscriber hereby irrevocably subscribes to purchase the Class A 1998 Warrants and the Class B 1998 Warrants (collectively, the "Warrants") in the form attached hereto as Exhibits B and C respectively for a price equal to $10,000 (the "Subscription Price"). 2. As part of the subscription, Subscriber herewith tenders: (a) two copies of this Agreement duly completed and executed by Subscriber. (b) payment of the Subscription Price made by wire transfer of immediately available funds in U.S. Dollars to the account of Research Frontiers Incorporated at Chase Manhattan Bank, 1064 Old Country Road, Plainview, New York 11803, Account No.: 904-709361, ABA Wire Code No.: 021 000 021. 3. Subscriber understands and agrees that the subscription contained herein shall not be deemed binding upon the Company until it is accepted by the Company and that the subscription may be rejected by the Company in its sole discretion for any reason. Subscriber further acknowledges and agrees that, subject to applicable law, this subscription is irrevocable. 4. If this subscription is not accepted by the Company, all Subscription Funds and the documents herewith delivered to the Company by Subscriber will be returned promptly to Subscriber. In such event, all proceeds theretofore received by the Company from the Subscriber will be refunded in full, without interest or deduction. 5. If this subscription is accepted by the Company, then the Company shall promptly countersign both copies of this Agreement and return one fully executed copy to Subscriber. All Subscription Funds of Subscriber shall be applied to the purchase of the Warrants which Warrants shall then be delivered to the Subscriber. All Subscription Funds of Subscriber shall be used for research and development, working capital, acquisitions, and for general corporate purposes in such amounts as the Company, in its discretion, deems appropriate. The Company may also, in its discretion, apply such Subscription Funds towards the development of products using the Company's technology through an investment by the Company in one or more joint ventures with third parties set up for such purposes, or may directly apply Subscription Funds to product development. B. Investor Representations 6. In order to induce the Company to accept the subscription hereby made, and recognizing that the Company will be relying thereon in determining whether to accept such subscription, Subscriber hereby represents and warrants to the Company as of the date of this subscription as follows: (a) Subscriber understands that the Warrants are a highly speculative investment and that Subscriber's financial situation is such that (i) Subscriber can afford to hold the Warrants for an indefinite period of time and to sustain a complete loss of its investment, and (ii) Subscriber has adequate means of providing for Subscriber's current needs and possible contingencies and has no need for liquidity in this investment in the Company. (b) Subscriber has received and carefully read the Company's 1997 Annual Report; the Company's Proxy Statement dated April 30, 1998; the Company's Annual Report on Form 10-K for the fiscal year ending December 31, 1997; and the Company's Quarterly Reports on Form 10-Q for the fiscal quarters ending March 31, 1998 and June 30, 1998 (collectively, the "Reports"). The Company has also made available to Subscriber all other documents and information that Subscriber has requested relating to an investment in the Company. (c) By virtue of Subscriber's knowledge and experience in financial and business matters, Subscriber is capable of evaluating the merits and risks of an investment in the Warrants. Subscriber has taken full cognizance of and understands all the risk factors related to the purchase of the Warrants, including, but not limited to, those set forth in the Company's reports and registration statements filed with the Securities and Exchange Commission or attached hereto as Exhibit A. (d) Subscriber understands that the Warrants are being offered and sold to Subscriber in reliance on specific provisions of federal and state securities laws of the United States of America and that the Company is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of Subscriber set forth herein in order to determine the applicability of such provisions. Accordingly, Subscriber agrees to notify the Company of any events which would cause the representation and warranties of Subscriber to be untrue or breached at any time after the execution of this Agreement by Subscriber. Subscriber understands that certificates representing the Warrants, and until the effectiveness of the Registration Statement, Shares issuable pursuant to the exercise of the Warrants, shall be stamped or otherwise imprinted with a legend substantially in the following form (in addition to any legend required under any applicable state securities laws): THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED PURSUANT TO THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS THERE IS A REGISTRATION STATEMENT THEN IN EFFECT COVERING SUCH SECURITIES OR AN EFFECTIVE EXEMPTION FROM SUCH REGISTRATION OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT UNDER THE CIRCUMSTANCES REGISTRATION IS NOT NECESSARY. (e) Subscriber is an "accredited investor" as defined in Rule 501 promulgated under the Securities Act of 1933, as amended. (f) Subscriber, and any person acting in concert with Subscriber, currently has no existing short position, and during the last 20 trading days had no short position, with respect to the common stock of the Company and agrees not to enter into any short sales or other hedging transactions with respect to any securities of the Company at any time after the execution of this Agreement by Subscriber and so long as any Warrants are held by or for the benefit of Subscriber or its affiliates or persons acting in concert with Subscriber or its affiliates or any Warrants are outstanding. (g) In evaluating the suitability of an investment in the Company, Subscriber has not relied upon any representations or other information (whether oral or written) from the Company, and its officers, directors, agents, employees or representatives, other than as set forth in the Reports. With respect to tax and other economic considerations of this investment, Subscriber is not relying for advice on the Company, or any officers, directors, employees or agents thereof. (h) Subscriber understands that Subscriber's subscription hereunder is not transferable or assignable, either before or after acceptance thereof by the Company, and that Warrants will only be issued in the name of Subscriber and may not be assigned without the consent of the Company. (i) The Warrants will be acquired for Subscriber's own account, for investment purposes only, and not with a view to distribution, assignment or resale to others. (j) Subscriber understands that no federal or state agency has made any finding or determination as to the fairness of this offering or any recommendation or endorsement relating to the Warrants. (k) The address heretofore provided to the Company by the Subscriber is the true and correct residence of the Subscriber, and Subscriber has no present intention of becoming a resident of any other state or jurisdiction. (If a corporation, trust or partnership, the Subscriber has its principal place of business at the address set forth below and was not organized for the specific purpose of acquiring the Warrants). (l) Subscriber acknowledges that any delivery of offering materials relating to the Warrants prior to the determination by the Company of Subscriber's suitability as an investor shall not constitute an offer of Warrants until such determination of suitability shall be made. (m) This Agreement has been duly authorized, validly executed, and delivered on behalf of Subscriber and is a valid and binding agreement enforceable in accordance with its terms, subject to general principles of equity and to bankruptcy or other laws affecting the enforcement of creditors' rights generally. (n) Subscriber has not taken any action that would cause the Company to be subject to any claim for commission or other fee or remuneration by any broker, finder, or other person and Subscriber hereby indemnifies the Company, and its officers, directors, shareholders and representatives, and each of their affiliates against any such claim caused by the actions of Subscriber or any of its employees or agents. (o) Subscriber will not make any offers or sales of the Shares other than pursuant to a registration statement under the Securities Act or pursuant to an exemption from registration under the Securities Act. The Subscriber will comply with applicable prospectus delivery requirements under the Exchange Act, and with all applicable securities laws upon resale of the Shares. (p) Subscriber will not, directly or through any affiliate or person acting in concert with Subscriber, (i) create the lowest reported sales price on the NASDAQ National Market, (or other exchange or market if the Shares are traded thereon) for the common stock of the Company on any trading day or (ii) offer to sell shares of such common stock at a price lower than the then prevailing bid price for the common stock on such market. (q) Subscriber hereby agrees to indemnify and hold harmless the Company, its directors, officers, agents, representatives, and each of their affiliates against any and all loss, liability, claim, damage and expense (including reasonable fees of attorneys and experts) as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), in reliance upon and in conformity with information furnished to the Company by Subscriber. C. Company Representations and Warranties 7. The Company hereby represents and warrants to the Subscriber that: (a) The Company is validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to enter into and to carry out and perform its obligations under this Agreement. (b) When issued and paid for on the date of closing, the Warrants will be validly issued, fully paid and non- assessable. (c) When and if executed by the Company, this Agreement will have been duly authorized, validly executed, and delivered on behalf of the Company and will be a valid and binding agreement enforceable in accordance with its terms, subject to general principles of equity and to bankruptcy or other laws affecting the enforcement of creditors' rights generally. (d) If this subscription is accepted by the Company, the Company will issue the Warrants in the name of Subscriber. Nothing in this section shall affect in any way Subscriber's obligations and agreement to comply with all applicable securities laws upon resale of the Warrants. (e) The Company will file and use its best efforts to cause to become effective, as promptly as possible, a registration statement ("Registration Statement") on Form S-3 under the Securities Act (or in the event that the Company is ineligible to use such form, such other form as the Company is eligible to use under the Securities Act) covering the resale of the Shares and shall take all action reasonably necessary to qualify the Shares under all applicable state "blue sky" laws. (f) As of the date hereof, the Company has reserved and the Company shall continue to reserve and keep available at all times, free of preemptive rights, shares of common stock for the purpose of enabling the Company to satisfy any obligation to issue Shares upon exercise of the Warrants. (g) The Company shall reimburse Subscriber for all reasonable costs and expenses relating to ongoing and periodic due diligence regarding the Company in connection with its investment in the Warrants, but not to exceed $25,000 in the aggregate. Upon request of the Company, the Subscriber will supply the Company with reasonable documentation supporting such expenses. D. Miscellaneous 8.

IN WITNESS WHEREOF, the Subscriber has executed this Subscription Agreement this 1st day of October, 1998. AILOUROS LTD., an Antigua and Barbuda corporation By:____________________________________________ Managing Director Accepted and Agreed To: RESEARCH FRONTIERS INCORPORATED By:____________________________________________ Robert L. Saxe, President By:____________________________________________ Joseph M. Harary, Vice President and General Counsel Date of Acceptance: October 1, 1998 EXHIBIT A RISK FACTORS Purchase of the Warrants involves a high degree of risk. In addition to the other information set forth in the Public Documents, prospective investors should carefully consider the following risk factors before making a decision to purchase the Warrants: History of Operating Losses and Accumulated Deficit Since inception, the Company has been primarily engaged in research and development activities. To date, the Company's revenues have been insufficient to fund operating expenses, and operating losses can be expected for the foreseeable future. There can be no assurance the Company will ever be profitable, or that if additional funding is necessary to fund the Company's operations, that additional funding will be available when needed, or if available, that its terms will be favorable or acceptable to the Company. Research and Development Company; Unproven Technology The Company is subject to all of the risks inherent in the development of new technologies and products. There can be no assurance that the Company's future operations will generate significant revenues or be profitable. The likelihood of the Company's success must be considered in light of the problems, expenses and delays frequently encountered in the commercialization and marketing of new technologies and the competitive environment in which the Company operates. All Products Being Developed Depend on Viability of the Company's Light Valve Technology All products being developed by the Company's licensees depend on the viability of the Company's light valve technology. No commercial products have been produced for sale. The Company has not developed any other technology. Thus, if commercially acceptable products cannot be developed from the Company's light valve technology, the Company will not be successful. Absence of Manufacturing and Marketing Capability The Company's light valve technology is currently licensed to eight companies and is being evaluated by others for possible exploitation in various commercial applications. In the past, some entities have evaluated the Company's technology without proceeding to enter into further negotiations or agreements with the Company. The Company intends to continue to exploit its light valve technology by licensing it to manufacturers of end products and to one or more other companies to manufacture the Company's light-controlling fluid suspensions and films. The Company anticipates that its licensee(s) would have primary responsibility for marketing and manufacturing activities. There can be, however, no assurance that any definitive future agreements or arrangements will materialize. To date, neither the Company nor any of its licensees has produced a commercial product incorporating the Company's light valve technology. The Company cannot control the activities of its licensees. There can be no assurance as to when or whether the licensees will produce any commercial product using the Company's light valve technology or, if produced, that such product will become commercially viable. Dependence on Key Personnel The success of the Company is dependent on, among other things, the services of its senior management, the loss of whose services could have a material adverse effect upon the prospects of the Company. Competition with Proven Technologies The Company's light valve technology will compete with other light control and display technologies which are being commercially exploited with great success, such as LEDs and LCDs. Companies with liquid crystal, electrochromic and possibly other technologies are now competing or probably will compete against the Company in the field of so-called "smart windows." In general, the companies which will compete against the Company have substantially greater financial, marketing, technical and other resources and name recognition than the Company. There can be no assurance that the Company's light valves (whose performance and long-term reliability have not yet been fully ascertained) will be able to displace other devices being used commercially or otherwise find a niche for commercial application. Technological Obsolescence While the Company believes that its light valves will have certain advantages over some existing display devices, other types of so-called "smart windows" and photochromic eyeglasses, there can be no assurance that one or more of the numerous existing companies which manufacture or may manufacture such products, or any company formed after the date hereof, will not be able to develop products using alternative technologies that would render the Company's products difficult to market or technologically or otherwise obsolete. Uncertain Patent Protection Although aspects of the Company's technology are covered by 19 United States patents, 3 pending patent applications in the United States, 32 foreign patents, and 59 foreign patent applications, a number of those patents cover earlier versions and features of the Company's light valves which the Company does not intend to exploit. Moreover, the issuance of a patent does not carry any certainty of successful application or commercial success. There can be no assurance that these patents will be upheld if the Company seeks to enforce its patent rights against an infringer or that the Company will have sufficient resources to prosecute its rights. The Company also relies, to a lesser extent, on trade secrets and confidential disclosure agreements to protect its technology. Neither the issuance of patents nor the use of trade secrets will necessarily protect the Company from other persons using technologies similar to those covered by the Company's patents or trade secrets. In addition, there can be no assurance that any particular aspect of the Company's technology will not be found to infringe the claims of other existing patents. No Cash Dividends The Company has never paid any cash dividends and does not anticipate paying any cash dividends for the foreseeable future. Volatility of Stock Price Since the initial public offering of the Company's securities in July 1986, the market for the Company's securities has been volatile. The trading price of the Company's securities may continue to fluctuate significantly based on, among other things, announcements by the Company and its competitors and price and volume fluctuations relating to high-technology companies generally. Dilution There will be immediate and substantial dilution to the purchasers of the Warrants offered hereby because the net tangible book value per share of the Common Stock after completion of the offering could be substantially less than the Exercise Price of the Warrants.

Exercise of Warrants. 1.1 During any Quarter and prior to 4:30 p.m. New York time on the Expiration Date, the Warrantholder shall during such Quarter exercise the Outstanding Amount of this Warrant by delivering to the Company a Notice of Exercise duly executed and completed by Warrantholder, at the office of the Company, 240 Crossways Park Drive, Woodbury, New York 11797-2033, Attention: Joseph M. Harary, together with payment in full in lawful money of the United States, of the portion of the Outstanding Amount of the Warrant being exercised by such Notice of Exercise. Such payment shall be made by wire transfer of immediately available funds to the account of Research Frontiers Incorporated at Chemical Bank, 1064 Old Country Road, Plainview, New York 11803, Account No.: 904-709361, ABA Wire Code No.: 021 000 021, or to such other account or place, as the Company may specify. Upon exercise, the Warrantholder shall receive the number of Shares equal to the Outstanding Amount being exercised divided by the applicable Exercise Price. Upon receipt of the aforesaid payment, the Company shall issue instructions to its transfer agent to issue such Shares to the Warrantholder within three business days of the Company's receipt of such payment. Provided that the entire Outstanding Amount during any Quarter has been exercised, and subject to the other restrictions contained in this Warrant or in the Subscription Agreement dated October 1, 1998 between the Company and the Warrantholder, the timing and number of Notices of Exercise delivered by the Warrantholder to the Company shall be at the discretion of the Warrantholder. The Company may treat any Notice of Exercise received by it by facsimile after 4:30 p.m. New York time to be received on the next business day. 1.2 The following definitions shall apply: 1.2.1 The "Exercise Price" shall mean the lesser of (i) $15.00 or (ii) 92% of the average of the high and low trading prices on the Nasdaq National Market (or other exchange or market if the Shares are traded thereon) for each of the seven trading days preceding the date that a Notice of Exercise is given. The Exercise Price in effect during a Quarter specified in a Put Notice may never be lower than the Floor Price specified by the Company in such Put Notice, and the Warrantholder's obligation to exercise this Warrant shall be suspended for so long as the Exercise Price is lower than the Floor Price. Nothing contained in the preceding sentence shall prevent the Warrantholder from voluntarily electing to exercise this Warrant at a price per Share equal to or greater than the Exercise Price, provided that such price is at least as high as the Floor Price. 1.2.2 "Notice of Exercise" shall mean a notice or notices delivered by the Warrantholder to the Company indicating (A) the portion of the Outstanding Amount of this Warrant being exercised, (B) the Warrantholder's Deposit/Withdrawal At Custodian (DWAC) instructions for delivery of the Shares, and (C) specifying the Warrantholder's calculation of (1) number of Shares to be issued to such Warrantholder, (2) the Exercise Price in effect for such Notice of Exercise, and (3) the remaining balance of the Outstanding Amount. Notwithstanding anything to the contrary contained herein, unless otherwise agreed to by the Company in writing, each Notice of Exercise shall be deemed to contain a representation by Warrantholder that, after giving effect to the Shares to be issued pursuant to such Notice of Exercise, the total number of shares of common stock of the Company deemed beneficially owned by the Warrantholder, together with all shares of the common stock of the Company deemed beneficially owned by the Warrantholder's "affiliates" as defined in Rule 144 of the Act, will not exceed 4.9% of the total issued and outstanding shares of the common stock of the Company. 1.2.3 The "Outstanding Amount" of this Warrant shall be the amount specified in any Put Notice given by the Company from time to time, reduced by the amount of this Warrant exercised by the Warrantholder during the Quarter specified in such Put Notice to which the Put Notice relates. Unless waived by the Company and the Warrantholder, the Outstanding Amount in any Quarter shall automatically be reduced to equal the lesser of: (1) an amount equal to (A) 7% of the daily dollar trading volume in the Company's common stock for the three month period ending on the day prior to the beginning of the Quarter specified in the Put Notice multiplied by (B) the number of trading days in the Quarter specified in the Put Notice, or (2) an amount equal to (A) 7% of the daily dollar trading volume in the Company's common stock for the three month period ending on the day prior to the beginning of the three month period specified in Section 1.2.3(1)(A) above, multiplied by (B) the number of trading days in the Quarter specified in the Put Notice. Unless waived by the Company in writing, on the last day of any Quarter and on the Expiration Date, the Warrantholder shall be deemed to have given a Notice of Exercise for any Outstanding Amount remaining on such date. 1.2.4 "Put Notice" shall mean the notice given to the Warrantholder or its specified agent by the Company and signed by an executive officer of the Company setting forth: (A) the amount chosen by the Company (which may be any amount from $0.00 to $1.5 million) to be the Outstanding Amount of this Warrant to be exercised by the Warrantholder during the Quarter, (B) the exact dates of the Quarter which shall be specified by the Company, (C) the Floor Price specified by the Company. The Company shall give the Warrantholder a Put Notice at least 30 days prior to the beginning of any Quarter specified in such Put Notice. The Company may amend any terms specified in such Put Notice (except that the Outstanding Amount may not be increased by the Company without the Warrantholder's consent) by delivery of an amendment to such Put Notice to the Warrantholder at any time prior to the beginning of such Quarter. Unless mutually agreed to in writing, the Company may not specify an Outstanding Amount which, when exercised in full, would result in the Warrantholder having exercised more than $15 million. As of the date of this Warrant, the Outstanding Amount shall be $0.00. If no Put Notice is given by the Company, the Outstanding Amount after the expiration of the Quarter specified in any prior Put Notice shall be $0.00. 1.2.5 "Quarter" shall mean any three-month period specified in a Put Notice. 1.3 Certificates representing Shares issued hereunder shall be stamped or otherwise imprinted with a legend substantially in the following form (in addition to any legend required under any applicable state securities laws): THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED PURSUANT TO THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS THERE IS A REGISTRATION STATEMENT THEN IN EFFECT COVERING SUCH SHARES OR AN EFFECTIVE EXEMPTION FROM SUCH REGISTRATION OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT UNDER THE CIRCUMSTANCES REGISTRATION IS NOT NECESSARY. Provided, however, that if the issuance of the Shares pursuant to the exercise of this Warrant are subject to an effective registration statement pursuant to Section 5 of the Securities Act of 1933, as amended, certificates representing the Shares shall not bear any restrictive legend. 2. Reclassification, Fractional Shares; Change in Management. 2.1 The Floor Price specified in any Put Notice, and the daily trading price of the common stock of the Company for any trading day used to calculate the Exercise Price, shall be adjusted proportionally to reflect any stock splits, stock dividends, reclassifications, combinations and similar transactions involving the common stock. 2.2 No fractional shares of common stock shall be issued upon the exercise of any Warrants evidenced hereby, but in lieu thereof the number of shares of common stock that are issuable upon any exercise shall be rounded up or down to the nearest whole share. 2.3 Either party may terminate this Warrant prior to the Expiration Date if there has been a change in management of the other party by providing such party with written notice of such election to terminate. 3. Prior Notice as to Certain Events. The Company shall mail to Warrantholder not less than ten (10) days prior to the date on which (a) a record will be taken for the purpose of determining the holders of Capital Stock entitled to subscription rights, or (b) a record will be taken (or in lieu thereof, the transfer books will be closed) for the purpose of determining the holders of Capital Stock entitled to notice of and to vote at the meeting of stockholders at which any consolidation, merger, dissolution, liquidation, winding up or sale of the Company shall be considered and acted upon. 4.
