The actual number of shares of Common Stock into which the Redeemable Prepaid Warrant (and warrants issuable to the Selling Stockholders upon certain redemptions thereof by the Company) are exercisable will depend upon future market conditions. Based upon current market conditions, as of November 14, 1997, the outstanding warrants being registered hereunder would be exercisable into approximately 699,362 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 securities issuable upon exercise of the Redeemable Prepaid Warrant (and warrants issuable to the Selling Stockholders upon certain redemptions thereof by the Company) to purchase Common Stock, 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 $5,000,000 REDEEMABLE PREPAID WARRANT AND WARRANTS ISSUABLE UPON CERTAIN REDEMPTIONS THEREOF This Prospectus relates to the sale from time to time by certain stockholders (the "Selling Stockholders") of Research Frontiers Incorporated, a Delaware corporation (the "Company") of an indeterminate number of shares of common stock, $0.0001 par value per share, of the Company issuable upon exercise of a $5,000,000 Redeemable Prepaid Warrant and warrants issuable to the Selling Stockholders upon certain redemptions thereof by the Company (the "Shares"). The actual number of shares of Common Stock into which the Redeemable Prepaid Warrant (and warrants issuable to the Selling Stockholders upon certain redemptions thereof by the Company) are exercisable will depend upon future market conditions. Based upon current market conditions, as of the date of this Prospectus, such warrants would be exercisable into approximately [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 Stockholders 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 Stockholders 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 STOCKHOLDERS" and "PLAN OF DISTRIBUTION". The Company has received $5,000,000 from the Selling Stockholders upon issuance of the Redeemable Prepaid Warrant, which amount will be credited toward payment of the exercise price of the Redeemable Prepaid Warrant, and the Company may receive in the future the exercise price of any warrants issuable to the Selling Stockholders upon certain redemptions by the Company of the Redeemable Prepaid Warrant, if any. The Company will not receive any proceeds from the sale of Common Stock by the Selling Stockholders. 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 $18,500. The Company has also agreed to indemnify the Selling Stockholders against certain liabilities, including liabilities arising under the Securities Act. The Company's Common Stock trades on the Nasdaq SmallCap Market under the symbol "REFR". On [November 14, 1997] as reported by Nasdaq, the last sales price of a share of Common Stock was [$8.50].

RISK FACTORS An investment in the Shares 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 short-term investments to fund its research and development of SPD 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 four 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, 2 pending patent applications in the United States, 24 foreign patents, and 66 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 Stockholders will only receive the $5,000,000 aggregate exercise price of the Redeemable Prepaid Warrant being registered hereunder which has already been received by the Company, or the exercise price of any warrants issuable to the Selling Stockholders in the event the Company makes certain redemptions thereof, if any. 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 [10,229,510] 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 and goggles, 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 Stockholders and will only receive the $5,000,000 aggregate exercise price of the Redeemable Prepaid Warrant which has already been received by the Company, or the exercise price of any warrants issuable to the Selling Stockholders in the event that the Company makes certain redemptions thereof, if any. The Company expects that any net proceeds from the exercise of the warrants will be used for working capital and general corporate purposes, including research and development. Pending utilization, the Company intends to invest such funds in money market funds and other interest-bearing obligations. SELLING STOCKHOLDERS The following table sets forth certain information regarding beneficial ownership of the Company's Common Stock as of [November __, 1997], adjusted to reflect the sale of the Common Stock by each Selling Stockholder. The persons named in the table have sole voting and investment power with respect to all Common Stock shown as beneficially owned by them, subject to community property laws where applicable. The information given assumes that all Common Stock received upon exercise of the warrants described herein which are held by the Selling Stockholders are sold. The Common Stock offered by the Selling Stockholders 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 Stockholders may sell all, a part, or none of the number of Common Stock offered by this Prospectus. None of the Selling Stockholders has 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 Redeemable Prepaid Warrant (and warrants issuable to the Selling Stockholders upon certain redemptions thereof by the Company) are exercisable into depends 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 Redeemable Prepaid Warrant. Therefore, the aggregate exercise price of the Redeemable Prepaid Warrant subscribed for by each 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 each Selling Stockholder.

Because the number of Shares into which the Redeemable Prepaid Warrant (and warrants issuable to the Selling Stockholders upon certain redemptions thereof by the Company) are exercisable into depends 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 Redeemable Prepaid Warrant. 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 after all obligations to the holders of Redeemable Prepaid Warrant have been satisfied; 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. On October 29, 1997, the Company sold pursuant to a private placement to the Selling Stockholders who are all accredited investors, Redeemable Prepaid Warrant with the aggregate exercise price of $5,000,000 which was paid to the Company at the closing. The Redeemable Prepaid Warrant is exercisable for a period of five years (which period may be extended under certain circumstances). The exercise price of the Redeemable Prepaid Warrant is the lesser of (a) 110% of the average of the high and low trading prices of the Company's Common Stock for the seven trading days prior to the closing date, and (b) 82% (subject to adjustment under certain circumstances) of the average of the high and low trading prices of the Company's Common Stock for the five trading days prior to any exercise date. The holder of a Redeemable Prepaid Warrant may not exercise such warrant at any time that the exercise price is less than or equal to $5.10 (the "Floor Price"); provided, however, that in the event that the closing price of the Company's Common Stock is less than or equal to the Floor Price for 60 consecutive calendar days, the foregoing prohibition on exercise will, upon the expiration of such 60-day period, be inoperative, subject to reinstatement in the event that subsequently the exercise price is equal to or greater than $8.37 for a period of ten consecutive trading days. Also, if the closing bid price of the Company's Common Stock is less than or equal to $3.00 on an exercise date, in lieu of issuing the shares of Common Stock to which the warrant holder is entitled, the Company has the option to pay the warrant holder an amount equal to the product of (x) the closing bid price of the Common Stock on the exercise date and (y) the number of shares which would have been issued upon such exercise. In addition, if the closing price per share of Common Stock is less than or equal to $6.00 for fifteen (15) consecutive trading days , the Company may redeem the warrant, in whole or in part, at a redemption price equal to 105% of the then outstanding amount of the warrants being redeemed payable in cash, together with one new five year Common Stock purchase warrant for every three shares of Common Stock underlying the unexercised portion of such redeemed warrant, with such new warrant having an exercise price of 115% of the bid price for the Common Stock on the day of redemption. If the closing price per share of Common Stock is greater than or equal to $14.00 for any fifteen (15) consecutive trading days after the registration statement of which this Prospectus is a part shall be declared effective, the Company may redeem the warrant, in whole or in part, at a redemption price equal to 100% of the then outstanding amount of the warrants (unless exercised by the Selling Stockholders prior to redemption) being redeemed upon 120 days' notice, such notice not to be given earlier than October 29, 1999. The Company is obligated to register the issuance of all shares of Common Stock issuable upon exercise of the Redeemable Prepaid Warrant (and warrants issuable to the Selling Stockholders upon certain redemptions thereof by the Company). Also, under certain circumstances, the Company may be required to redeem the outstanding warrants at a premium over the then outstanding amount, which amount shall equal 115% of the then outstanding amount in the event of a merger, consolidation, spin off or other extraordinary corporate action, and at an amount equal to 125% of the then outstanding amount if the Company defaults on certain obligations to the Selling Stockholders. 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. PLAN OF DISTRIBUTION The Selling Stockholders are entitled to distribute from time to time the Common Stock issuable upon exercise of the Redeemable Prepaid Warrant (and warrants issuable to the Selling Stockholders upon certain redemptions thereof by the Company). Based upon current market conditions, as of [November __, 1997], the outstanding warrants being registered hereunder would be exercisable into approximately [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 such warrants. The Company will not receive any proceeds from the sale of Common Stock by the Selling Stockholders who hold Redeemable Prepaid Warrant and will only receive the $5,000,000 aggregate exercise price of the Redeemable Prepaid Warrant being registered hereunder which has already been received by the Company, or the exercise price of any warrants issuable to the Selling Stockholders upon certain redemptions thereof by the Company, if any. The distribution of the Common Stock by the Selling Stockholders 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 Stockholders 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 Stockholders 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.

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.

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.

Right to Purchase Shares of Common Stock of Research Frontiers Incorporated _____________________________ Common Stock Prepaid Warrant Research Frontiers Incorporated, a Delaware corporation having an address at 240 Crossways Park Drive, Woodbury, New York 11797- 2033 (the "Company"), hereby certifies that the entity listed below or any other Warrant Holder is entitled, on the terms and conditions set forth below, to purchase from the Company at any time after the date hereof and ending sixty (60) months after the date hereof (as such period may be extended pursuant to Section 5A of the Registration Rights Agreement) (the "Termination Date") fully paid and nonassessable shares of Common Stock, $.0001 par value, of the Company together with any associated Common Stock purchase rights issued under the Stockholder Rights Plan dated February 16, 1993 or any similar stockholder rights plan of the Company adopted after the date hereof (the "Common Stock"). The aggregated purchase price of the Warrants is $5,000,000 (the "Outstanding Amount"). 1. Definitions. (a) the term "Exercise Price" shall mean the lesser of (i) the Initial Exercise Price or (ii) 82% of the average of the high and low trading prices on the Nasdaq SmallCap Market (or the Nasdaq National Market if the Common Stock is included therein) for each of the previous five trading days as of the date of exercise (the "Valuation Period"); provided, however, that in the event that the Registration Statement referred to in Section 2(b) of the Registration Rights Agreement is not declared effective by the Commission by the 120th day following the Closing Date, the Initial Exercise Price shall be reduced by 2% for each month or portion thereof that the Registration Statement shall not be declared effective, such reduction pursuant to this proviso not to exceed 8% or, in lieu of such reduction, the Company may elect, by irrevocable notice to the Warrant Holder received not later than the 120th day following the Closing Date, to pay the Warrant Holder an amount equal to 2% of the Outstanding Amount in shares of Common Stock for each month or portion thereof that the Registration Statement shall not be declared effective, such shares of Common Stock to be valued at the average of the high and low trading prices on the Nasdaq SmallCap Market (or the Nasdaq National Market if the Common Stock is included therein) for each of the five trading days immediately preceding the end of each such month (or, if the Registration Statement is declared effective during such month, for each of the five trading days immediately preceding the date the Registration Statement is declared effective) and to be issued within five (5) days after the end of each such month or effective date, as the case may be. (b) the term "Initial Exercise Price" shall mean $10.21. (c) the term "Warrant Holder" shall mean the Purchaser or any permitted assignee under the Subscription Agreement of all or any portion of this Warrant at any given time. (d) the term "Warrant Shares" shall mean the shares of Common Stock or other securities issuable upon exercise of this Warrant. (e) other terms used herein which are defined in the Subscription Agreement, dated as of October 29, 1997 (the "Agreement"), or the Registration Rights Agreement, dated as of October 29, 1997 (the "Registration Rights Agreement"), shall have the same meanings herein as therein. 2. Exercise at the Option of the Warrant Holder. The Holder of this Warrant shall have the following exercise rights. (a) Holder's Right to Exercise. This Warrant shall be exercisable at any time after the Closing Date, in whole or in part, at the option of the Warrant Holder, into fully paid, validly issued and nonassessable shares of Common Stock. If this Warrant is exercised in part, the portion of this Warrant not so exercised shall remain entitled to the exercise rights provided herein. (b) Exercise Price. Except as stated in paragraphs 2(d) and 9 of this Warrant, the Outstanding Amount of this Warrant that is exercised into shares of Common Stock at the option of the Holder shall be exercised into the number of shares of Common Stock which results from application of the following formula: P ============== Exercise Price P = Outstanding Amount of this Warrant submitted for exercise The number of shares of Common Stock into which the Outstanding Amount of this Warrant hereto may be exercised pursuant to this Section 2 is hereinafter referred to as the "Exercise Rate." (c) Paragraph 4 Transaction Redemption. In the event that there is a definitive agreement executed for a Paragraph 4 Transaction (as hereinafter defined) the Company shall notify the Warrant Holder in writing of the execution of such a definitive agreement, and the Warrant Holder may elect at any time up to 5 days prior to the effective date of such Paragraph 4 Transaction to cause the Company to redeem this Warrant, in whole or in part, at a redemption price equal to 115% of the Outstanding Amount at the time of election. (d) Soft Floor Provision. The Warrant Holder may not exercise this Warrant at any time that the Exercise Price is less than or equal to $5.10 (the "Floor Price"); provided, however, that in the event that the closing price of the Common Stock on the Nasdaq SmallCap Market (or the Nasdaq National Market if the Common Stock is included therein) is less than or equal to the Floor Price for sixty (60) consecutive calendar days, the prohibition on exercise set forth in this Section 2(d) will, upon the expiration of such sixty (60) day period, be inoperative, subject to reinstatement in the event that the Exercise Price is equal to or greater than $8.37 for a period of ten (10) consecutive trading days. (e) Mechanics of Exercise. In order to exercise this Warrant (in whole or in part) into full shares of Common Stock, the Warrant Holder shall surrender this Warrant, duly endorsed, by either overnight or 2-day courier, to the principal office of the Company, and shall give written notice in the form of EXHIBIT 1 hereto (the "Notice of Exercise") by facsimile (with the original of the Notice of Exercise forwarded with the foregoing courier) to the Company at such office (by 12:00 noon on the Holder Exercise Date (defined below) if the trading price of the Common Stock is less than or equal to $3.00 at such time) that the Holder elects to exercise the Outstanding Amount specified therein, which Notice of Exercise and election shall be irrevocable by the Holder; provided, however, that the Company shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon such exercise unless either the Warrant evidencing the Outstanding Amount is delivered to the Company as provided above, or the Warrant Holder notifies the Company that such Warrant(s) have been lost, stolen or destroyed and executes an agreement reasonably satisfactory to the Company to indemnify the Company from any loss incurred by it in connection with such Warrants. The Company shall use its best efforts to issue and deliver within three business days after delivery to the Company of such Warrant(s), or after receipt of such agreement and indemnification, to such Warrant Holder at the address of the Warrant Holder, or to its designee, a certificate or certificates for the number of shares of Common Stock to which the Warrant Holder shall be entitled as aforesaid, together with a calculation of the Exercise Rate and a Warrant or Warrants for the Outstanding Amount not submitted for exercise. The effective date of exercise (the "Holder Exercise Date") shall be deemed to be the date on which the Company receives by facsimile the Notice of Exercise, and the person or persons entitled to receive the shares of Common Stock issuable upon such exercise shall be treated for all purposes as the record holder or holders of such shares of Common Stock on such date. (f) Company Cash Election. Notwithstanding the provisions of this Section 2, in the event that the closing bid price of the Common Stock on the Nasdaq SmallCap Market (or the Nasdaq National Market if the Common Stock is included therein) is less than or equal to $3.00 on the Holder Exercise Date, in lieu of issuing the shares of Common Stock to which the Warrant Holder is entitled pursuant to this Section 2, the Company shall have the option, upon irrevocable notice received by the Warrant Holder by facsimile not later than 1:00 p.m. on the Holder Exercise Date, to pay the Warrant Holder an amount (the "Cash Election Amount") equal to the product of (x) the closing bid price of the Common Stock on the Holder Exercise Date and (y) the number of shares of Common Stock to which the Warrant Holder would have been entitled pursuant to this Section 2 but for the provisions of this Section 2(f). 3. Exercise on Termination Date. At the Termination Date, the then Outstanding Amount of Warrants shall be automatically exercised for Common Stock in accordance with the terms of this Warrant without notice. The Company shall use its best efforts to issue and deliver within three business days after delivery to the Company of this Warrant, or after receipt of the agreement and indemnification described in paragraph 2(e) above, to the Warrant Holder at the address of the Warrant Holder, or to its designee, a certificate or certificates for the number of shares of Common Stock to which the Warrant Holder shall be entitled hereunder. The person or persons entitled to receive the shares of Common Stock issuable upon such exercise shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Termination Date. The Termination Date shall be a "Holder Exercise Date" for purposes of this Warrant. 4. Paragraph 4 Transactions. If at any time (i) there occurs any consolidation or merger of the Company with or into any other corporation or other entity or person (whether or not the Company is the surviving corporation) or there occurs any other corporate reorganization or transaction or series of related transactions, and as a result thereof the stockholders of the Company pursuant to such merger, consolidation, reorganization or other transaction shall own in the aggregate less than 50% of the voting power and common equity of Company or the ultimate parent corporation or other entity surviving or resulting from such merger, consolidation, reorganization or other transaction, (ii) the Company transfers all or substantially all of the Company's assets to another corporation or other entity or person or (iii) the Company shall fix a record date for the declaration of a material distribution or dividend (x) payable in securities or assets (other than shares of Common Stock) or (y) payable in cash but other than out of the surplus of the Company in accordance with the Delaware General Corporation Law (each a "Paragraph 4 Transaction"), then, if the Warrant Holder shall not have elected pursuant paragraph 2(c) hereof to cause this Warrant to be redeemed by the Company, the Warrant Holder may (by exercising this Warrant pursuant to paragraph 2 hereof) participate in any such Transaction as a class with holders of Common Stock on the same basis as if this Warrant had been exercised one day prior to the effective date (or record date for such distribution or dividend) of such Transaction and the Company shall make provision for the rights of the Warrant Holder specified in this paragraph 4 in any such Paragraph 4 Transaction. 5. Redemption at the Option of the Company. This Warrant may not be redeemed at the option of the Company except in accordance with the terms of this Section 5. (a) To the extent the Company shall have funds legally available for such payment, the Company may, provided the closing price per share of Common Stock is less than or equal to $6.00 for fifteen (15) consecutive trading days immediately prior to the date of redemption, redeem this Warrant, in whole or in part, at a redemption price equal to 105% of the then Outstanding Amount of the Warrants being redeemed upon 30 days' notice and payable in cash, together with one new five year Common Stock Purchase Warrant containing the same terms and conditions as this Warrant for every three shares of Common Stock underlying the unexercised portion of such redeemed Warrant, with an exercise price of 115% of the bid price for the Common Stock on the Nasdaq SmallCap Market (or the Nasdaq National Market if the Common Stock is included therein) on the day of redemption (the "Redemption Warrant"), such Redemption Warrants, as a condition to such redemption, to be reasonably satisfactory to the Warrant Holder. (b) To the extent the Company shall have funds legally available for such payment, the Company may, provided the closing price per share of Common Stock is greater than or equal to $14.00 for any fifteen (15) consecutive trading days after the Registration Statement shall be declared effective, redeem this Warrant, in whole or in part, at a redemption price equal to 100% of the then Outstanding Amount of the Warrants being redeemed upon 120 days' notice, such notice not to be given earlier than the second anniversary of the Closing Date and payable in cash, provided that the Registration Statement shall be effective on the date of redemption. (c) Upon irrevocable notice to the Warrant Holder of the redemption of this Warrant, this Warrant shall be redeemed by the Company at the redemption price herein specified. In the event that less than the Outstanding Amount of this Warrant is redeemed, then the Company shall issue and deliver within three (3) business days after delivery to the Company of this Warrant, to such Warrant Holder at the address of the Warrant Holder, a Warrant for the Outstanding Amount of this Warrant not redeemed by the Company. 6.

(a) Subject to the terms and conditions of this Warrant, as soon as practicable after the exercise of this Warrant in full or in part, and in any event within three (3) trading days thereafter, the Company at its expense (including, without limitation, the payment by it of any applicable issue taxes) will cause to be issued in the name of and delivered to the Warrant Holder, or as the Warrant Holder (upon payment by the Warrant Holder of any applicable transfer taxes) may lawfully direct, a certificate or certificates for the number of fully paid and non-assessable shares of Common Stock to which the Warrant Holder shall be entitled on such exercise, together with any other stock or other securities or property (including cash, where applicable) to which the Warrant Holder is entitled upon such exercise. 7. Fractional Shares. No fractional shares of Common Stock or scrip representing fractional shares of Common Stock shall be issuable hereunder. 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. 8. Covenants of the Company. (a) The Company will not take any action specified in paragraph 4(iii) (y) hereof without the Warrant Holder's prior written consent. (b) The Company shall use its reasonable best efforts to insure that a Registration Statement under the Act covering the issuance of the Warrant Shares and the resale or other disposition thereof by the Warrant Holder is effective as provided in the Registration Rights Agreement. (c) The Company shall take all necessary actions and proceedings as may be required and permitted by applicable law, rule and regulation, including, without limitation, those of the NASD, for the legal and valid issuance of this Warrant and the Warrant Shares to the Warrant Holder under this Warrant. (d) From the date hereof through the Termination Date, the Company shall take all steps reasonably necessary to insure that the Common Stock remains included in the Nasdaq SmallCap Market (or the Nasdaq National Market if the Common Stock is included therein). (e) The Company shall not amend its Certificate of Incorporation or Bylaws so as to constitute a breach of the Company's obligations hereunder. (f) The Company shall at all times reserve and keep available, solely for issuance and delivery as Warrant Shares hereunder, such shares of Common Stock as shall from time to time be issuable as Warrant Shares; provided, however, that the number of shares so reserved shall at all times be at least 1,000,000 shares. The number of shares so reserved may be reduced by the number of shares actually delivered pursuant to exercise of the Warrants (provided that in no event shall the number of shares so reserved be less than the number required to satisfy the remaining exercise rights on the outstanding Warrants and the Redemption Warrants) and the number of shares so reserved shall be increased to reflect stock splits and stock dividends and distributions. (g) The Warrant Shares, when issued in accordance with the terms hereof, will be duly authorized, validly issued, fully paid and non-assessable. The Company has authorized and reserved for issuance to the Warrant Holder the requisite number of shares of Common Stock to be issued pursuant to this Warrant. (h) With a view to making available to the Warrant Holder the benefits of Rule 144 promulgated under the Act and any other rule or regulation of the SEC that may at any time permit the Warrant Holder to sell securities of the Company to the public without registration, the Company agrees to use its reasonable best efforts to: (i) make and keep public information available, as those terms are understood and defined in Rule 144, at all times; (ii) file with the SEC in a timely manner all reports and other documents required of the Company under the Act and the Exchange Act; and (iii) furnish to any Warrant Holder forthwith upon request a written statement by the Company that it has complied with the reporting requirements of Rule 144 and of the Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as may be reasonably requested to permit any such Warrant Holder to take advantage of any rule or regulation of the SEC permitting the selling of any such securities without registration. 9. Adjustment of Exercise Price and Number of Shares. The number of, and kind of, securities purchasable upon exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time if: (a) Subdivisions, Combinations and Other Issuances. The Company shall subdivide its outstanding securities as to which exercise rights under this Warrant exist, by split-up, spin-off, or otherwise, or combine its outstanding securities as to which exercise rights under this Warrant exist. In such event, the number of Warrant Shares as to which this Warrant is exercisable as of the date of such subdivision, split-up, spin- off or combination shall be proportionately increased in the case of a subdivision, or proportionately decreased in the case of a combination. (b) Stock Dividend. The Company declares a dividend or other distribution on Common Stock payable in Common Stock or other securities or rights convertible into Common Stock ("Common Stock Equivalents") without payment of any consideration by holders of Common Stock for the additional shares of Common Stock or Common Stock Equivalents (including the additional shares of Common Stock issuable upon exercise or conversion thereof). In such event, the number of shares of Common Stock for which this Warrant may be exercised shall be increased as of the record date (or the date of such dividend distribution if no record date is set) for determining which holders of Common Stock shall be entitled to receive such dividends, in proportion to the increase in the number of outstanding shares (and shares of Common Stock issuable upon conversion of all such securities convertible into Common Stock) of Common Stock as a result of such dividend, and the Exercise Price shall be adjusted so that the aggregate number of all the Warrant Shares issuable hereunder immediately after the record date (or on the date of such distribution, if applicable), for such dividend shall equal the aggregate number so issuable immediately before such record date (or on the date of such distribution, if applicable). (c) Other Distributions. The Company distributes to holders of its Common Stock, other than as part of its dissolution, liquidation or the winding up of its affairs, any shares of its capital stock, any evidence of indebtedness or any of its assets (other than cash, Common Stock or securities exercisable into Common Stock). In such event, the Exercise Price of this Warrant shall be adjusted in good faith by the Company's Board of Directors to reflect the value distributed on each share of Common Stock. (d) Merger, etc. There shall be, through any means, a merger or consolidation of the Company with or into or, through any means, a transfer of all or substantially all of the assets of the Company to another entity. In such event, the Warrant Holder shall be entitled to receive upon such transfer, merger or consolidation becoming effective, the number of shares or other securities or property of the Company or of the successor corporation resulting from such merger or consolidation, which would have been received by the Warrant Holder for the shares of stock subject to this Warrant had this Warrant been exercised just prior to such transfer, merger or consolidation becoming effective or to the applicable record date thereof, as the case may be. (e) Reclassification etc. There shall be, through any means, a reorganization or reclassification of the securities as to which exercise rights under this Warrant exist into the same or a different number of securities of any other class or classes. In such event, the Warrant Holder shall thereafter be entitled to receive upon exercise of this Warrant the number of shares or other securities or property resulting from such reorganization or reclassification, which would have been received by the Warrant Holder for the shares of stock subject to this Warrant had this Warrant at such time been exercised. 10. Reservation of Stock Issuable Upon Exercise. (a) Reservation Requirement. The Company shall 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 of Common Stock upon exercise of all of the Warrants pursuant hereto. (b) Default. If the Company does not have a sufficient number of shares of Common Stock available to satisfy the Company's obligations to a Warrant Holder upon receipt of a Notice of Exercise or is otherwise unable to issue such shares of Common Stock in accordance with the terms of this Warrant and such condition shall remain unremedied for a period of forty-five (45) days after the Company's receipt of a Notice of Exercise (an "Exercise Default"), then from and after the fifth (5th) day following an Exercise Default, the Company shall be obligated to pay each Warrant Holder 2% per month of the then Outstanding Amount of this Warrant for which an Exercise Notice has been sent (the "Default Charge") in cash on or prior to the fifth day after the end of the month for which the Default Charge is payable. In addition, in the event that an Exercise Default is not cured within 180 days after the date of the Notice of Exercise or the Default Charge is not paid within 5 days after the end of each month for which it is due, this Warrant may, at the Warrant Holder's option, be redeemed in whole or in part at a redemption price equal to 125% of the Outstanding Amount thereof, together with any unpaid Default Charge. 11. No Reissuance of Warrants. No Warrants acquired by the Company by reason by redemption, purchase, exercise or otherwise shall be reissued, and all such Warrants shall be retired. 12. Holder's Rights if Shares are Delisted or if Trading in Common Stock is Suspended. In the event that at any time on or after the date hereof, and prior to the Termination Date, trading in the shares of the Common Stock is suspended on the Nasdaq SmallCap Market (or the Nasdaq National Market if the Common Stock is included therein) for a period of five consecutive trading days, other than as a result of the suspension of trading in securities in general, or if such shares are delisted from the Nasdaq SmallCap Market (or the Nasdaq National Market if the Common Stock is included thereon) then, at the Warrant Holder's option, upon notice to the Company, the Company shall redeem such Holder's Warrants at a redemption date designated by such Holder, and at the redemption price equal to 125% of the then Outstanding Amount of the Warrant. 13. Limitations on Holder's Right to Exercise. Notwithstanding anything to the contrary contained herein, each Exercise Notice shall be deemed to contain a representation that, after giving effect to the shares of the Common Stock to be issued pursuant to such Exercise Notice, the total number of shares of the Common Stock deemed beneficially owned by the Warrant Holder, together with all shares of the Common Stock deemed beneficially owned by the Warrant Holder'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. 14. Registration Suspension. In the event that at any time or from time to time any registration statement with respect to the Common Stock issuable upon conversion of this Warrant is suspended or trading in the Common Stock on the Nasdaq SmallCap Market (or the Nasdaq National Market if the Common Stock is included therein) is suspended for a period of time ("Blackout Period"), the Termination Date hereunder shall be extended for a period equal to 1.5 times the number of days in such Blackout Period. Furthermore, additional provisions pertaining to the suspension of effectiveness of such registration statement set forth in Paragraph 5A of the Registration Rights Agreement, shall be applicable in the event of a Blackout Period, and are specifically incorporated by reference herein. 15. Payment of Expenses. The Company agrees to pay all reasonable fees and expenses, including reasonable attorneys' fees, which may be incurred by the Warrant Holder in enforcing the provisions of this Warrant, the Subscription Agreement or the Registration Rights Agreement (as defined in the Subscription Agreement). 16. Defaults. The following shall constitute "Events of Default": (a) The Company refuses at any time to honor any Notice of Exercise issued in accordance with the terms of Paragraph 2 hereof; or (b) Any of the representations or warranties made by the Company herein, in the Subscription Agreement, or in any certificate or financial or other statements heretofore or hereafter furnished by or on behalf of the Company in connection with the execution and delivery of this Warrant or the Subscription Agreement shall be false or misleading in any material respect and such condition (to the extent capable of being cured) shall continue uncured for a period of ten (10) business days after the Company has become aware thereof or, in the exercise of reasonable care, should have become aware thereof; or (c) The Company shall fail to perform or observe in any material respect any covenant or agreement in the Subscription Agreement, or any other covenant, term, provision, condition, agreement or obligation of the Company under this Warrant (except Section 10(a) hereof) and such failure shall continue uncured for a period of ten (10) business days after the Company has become aware thereof or, in the exercise of reasonable case, should have become aware thereof; or (d) The Company shall (1) become insolvent; (2) admit in writing its inability to pay its debts generally as they mature; (3) make an assignment for the benefit of creditors or commence proceedings for its dissolution; or (4) apply for or consent to the appointment of a trustee, liquidator or receiver for it or for a substantial part of its property or business; or (e) A trustee, liquidator or receiver shall be appointed for the Company or for a substantial part of its property or business without its consent and shall not be discharged within ninety (90) days after such appointment; or (f) Any governmental agency or any court of competent jurisdiction at the instance of any governmental agency shall assume custody or control of the whole or any substantial portion of the properties or assets of the Company and shall not be dismissed within ninety (90) days thereafter; or (g) Any money judgment (including any arbitration award, but only if reduced to a judgment), writ or warrant of attachment, or similar process in excess of Two Hundred and Fifty Thousand Dollars ($250,000) in the aggregate shall be entered or filed against the Company or any of its properties or other assets and shall remain unpaid, unvacated, unbonded or unstayed for a period of sixty (60) days or in any event later than ten (10) days prior to the date of any proposed sale thereunder; and (h) Bankruptcy, reorganization, insolvency or liquidation proceedings or other similar proceedings, or relief under any bankruptcy law or any law for the relief of debt, shall be instituted by or against the Company and, if instituted against the Company, shall not be dismissed within sixty (60) days after such institution or the Company shall by any action or answer approve of, consent to, or acquiesce in any such proceedings or admit to any allegations of, or default in answering a petition filed in any such proceeding. Unless an Event of Default shall have been waived in writing by the Warrant Holder (which waiver shall not be deemed to be a waiver of any subsequent default) at the option of and on notice by the Warrant Holder and in the Warrant Holder's sole discretion, this Warrant shall be redeemed at a redemption price equal to 125% of the Outstanding Amount of the Warrant, the Company's obligation to redeem this Warrant having arisen immediately prior to the occurrence of such Event of Default. 17. Bankruptcy. The Company and the Warrant Holder agree that the rights of the Warrant Holder under this Warrant shall, upon the occurrence of any Event of Default specified in paragraph 16(d), (e), (f) or (h) or upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, rank prior and in preference to the rights of the holders of Common Stock. 18. No Impairment. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Warrant Holder against impairment. Without limiting the generality of the foregoing, the Company (a) will not increase the par value of any Warrant Shares above the amount payable therefor on such exercise, (b) will take all such action as may be reasonably necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares on the exercise of this Warrant and (c) comply fully with all of the provisions of this Warrant, including but not limited to the non- impairment provisions of paragraphs 4 and 9(a)-(e). 19. Notice of Adjustments; Notices. Whenever the Exercise Price shall be adjusted pursuant to the terms hereof, the Company shall execute and deliver to the Warrant Holder a certificate setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated and the Exercise Price hereunder after giving effect to such adjustment, and shall cause a copy of such certificate to be mailed (by first class mail, postage prepaid) to the Warrant Holder. 20. Rights as Stockholder. Prior to exercise of this Warrant, the Warrant Holder shall not be entitled to any rights as a stockholder of the Company with respect to the Warrant Shares, including without limitation, the right to vote such shares, receive dividends or other distributions thereon or be notified of stockholder meetings. However, in the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution, any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right, the Company shall mail to each Warrant Holder, at least 10 days prior to the date specified therein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and the amount and character of such dividend, distribution or right. 21. Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement or security reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, on surrender and cancellation of such Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like tenor. 22. Specific Enforcement; Consent to Jurisdiction; Waiver of Jury Trial.

Such best efforts by the Company shall include without limitation the following: (a) The Company shall, as soon as practicable after the date hereof but in no event later than thirty (30) days after the date hereof, file (i) a registration statement with the Commission pursuant to Rule 415 under the Securities Act 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 Registrable Securities so requested to be registered by the Holder ("Registration Statement"); (ii) such blue sky filings as shall have been requested by the Holder; and (iii) any required filings with the National Association of Securities Dealers, Inc. or exchange or market where the Shares are traded. Thereafter the Company shall use its best efforts to have such Registration Statement and other filings declared effective as promptly as practicable. (b) (i) If the Company fails to file a Registration Statement complying with the requirements of this Registration Rights Agreement within 30 days from the date hereof or if such Registration Statement has not become effective within 270 days from the Closing Date, the Holder shall have, in addition to and without limiting any other rights it may have at law, in equity or under the Warrants, the Agreement or this Registration Rights Agreement (including the right to specific performance), the right to receive, as liquidated damages, the payments as provided in subparagraph (ii) of this section. (ii) If after 270 days from the Closing Date the Registration Statement has not been declared effective by the Commission, then upon demand of such Holder, the Company shall redeem all the Warrants held by such Holder at a redemption price equal to 115% of the Outstanding Amount of the Warrants. (c) The Company shall enter into such customary agreements and take all such other reasonable actions in connection therewith in order to expedite or facilitate the disposition of such Registrable Securities and, in such connection: (i) make such representations and warranties to the Holder as the Holder may reasonably request; (ii) cause to be delivered to the sellers of Registrable Securities opinions of counsel to the Company, dated the effective date of the Registration Statement (which counsel, and opinions (in form, scope and substance), shall be reasonably satisfactory to the appointed representative or counsel of the Holder), addressed to the Holder covering the matters customarily covered in opinions requested in secondary underwritten offerings; and (iii) the Company shall deliver such documents and certificates as may be reasonably requested by the Holder to evidence compliance with clause (i) above and with any customary conditions contained in any agreement entered into by the Company in connection herewith; the foregoing in this paragraph 2(c) shall be done at each closing as and to the extent required thereunder; provided, however, the foregoing in paragraph 2(c) shall not be required on more than two (2) occasions. (d) The Company shall make available for inspection by a representative or representatives of the Holder and any attorney or accountant retained by such Holder, all financial and other records customary for such purposes, pertinent corporate documents and properties of the Company, and cause the Company's officers, directors and employees to supply all information reasonably requested by any such representative, attorney or accountant in connection with such Registration Statement. The Holder will agree to keep all non-public information supplied to it confidential until such information is included in the Registration Statement. 3. Expenses of Registration. Subject to the provisions of Section 10.2 of the Agreement, all Registration Expenses incurred in connection with any registration, qualification or compliance with registration pursuant to this Agreement shall be borne by the Company, and all Selling Expenses shall be borne by the Holder. 4. Registration on Form S-3. The Company shall use its best efforts to qualify for registration on Form S-3 or any comparable or successor form or forms, or in the event that the Company is ineligible to use such form, such form as the Company is eligible to use under the Securities Act. The foregoing is not intended to require the Company to pay dividends in order to use Form S-3. 5. Registration Procedures. In the case of each registration effected by the Company pursuant to this Agreement, the Company will keep the Holder advised in writing as to the initiation of each registration and as to the completion thereof. At its expense, the Company will use its best efforts to: (a) Keep such registration effective for the period ending sixty (60) months, as extended pursuant to Section 5A hereof, after the Date of Issue (in the case of the Registration Statement for the Shares issuable upon exercise of the Warrants) or until the Holder has completed the distribution of the Shares issuable upon exercise of the Warrants, whichever first occurs. (b) Furnish such number of prospectuses, amendments and supplements thereto, and other documents incident- thereto, as the Holder from time to time may reasonably request. (c) Prepare and file with the Commission such amendments and posteffective amendments to a Registration Statement as may be necessary to keep such Registration Statement effective for the applicable period; cause the related Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act; and comply with the provisions of the Securities Act applicable to it with respect to the disposition of all securities covered by such Registration Statement during the applicable period in accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement or supplement to such Prospectus; (d) Notify each Holder of Registrable Securities included in the Registration Statement and their counsel and (if requested by any such Person) confirm such notice (a "Notice") in writing, (1) when a Prospectus or any Prospectus supplement or post- effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective, (2) of any request by the Commission for amendments or supplements to a Registration Statement or related Prospectus or for additional information, (3) of the issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purposes, (4) if at any time the representations and warranties of the Company contained in agreements contemplated by Section 2(c) cease to be true and correct, (5) of the receipt by the Company of any notification with respect to the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, (6) of the happening of any event as a result of which the Prospectus included in the Registration Statement (as then in effect) contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus or any preliminary Prospectus, in light of the circumstances under which they were made) not misleading and (7) of the Company's reasonable determination that a post-effective amendment to a Registration Statement would be appropriate or that there exist circumstances not yet disclosed to the public which make further sales under such Registration Statement inadvisable pending such disclosure and post-effective amendment; (e) Upon the occurrence of any event contemplated by Section 5(d)(2)-(7) and immediately upon the expiration of any Blocking Period (as defined in Section 5A), prepare, if the occurrence of such event or period requires such preparation, a supplement or post-effective amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, such Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading; (f) Make every reasonable effort to obtain the withdrawal of any order suspending the effectiveness of the Registration Statement, or the lifting of any suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction, at the earliest possible moment; (g) Insure that all Registrable Securities subject to the Registration Statement shall at all times be registered or qualified for offer and sale under the securities or blue sky laws of such jurisdictions as any Holder reasonably requests in writing; use its best efforts to keep each such registration or qualification effective, including through new filings or amendments or renewals, during the period such Registration Statement is required to be kept effective and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by the applicable Registration Statement; provided, however, that the Company will not be required to qualify to do business or take any action that would subject it to taxation or general service of process in any jurisdiction where it is not then so qualified or subject; (h) Use its best efforts to cause the Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of such Registrable Securities in accordance with the chosen method or methods of distribution; and (i) Cause all Registrable Securities included in such Registration Statement to be listed, by the date of first sale of Registrable Securities pursuant to such Registration Statement, on the principal securities exchange or automated interdealer system on which the same type of securities of the Company are then listed or traded. 5A. Suspension of Effectiveness. The Company may suspend dispositions under the Registration Statement and notify the Holder that it may not sell the Registrable Securities pursuant to any Registration Statement or Prospectus (a "Blocking Notice") if the Company's management determines in its reasonable good faith judgment that the Company's obligation to ensure that such Registration Statement and Prospectus are current and complete would require the Company to take actions that might reasonably be expected to have a materially adverse detrimental effect on the Company and its stockholders; provided that such suspension pursuant to a Blocking Notice or the Notice described below or as a result of the circumstances described in 5(d)(2)-(7) may not exceed sixty (60) days (whether or not consecutive) in any twelve (12) month period. The Holder agrees by acquisition of the Registrable Securities that, upon receipt of a Blocking Notice or "Notice" from the Company of the existence of any fact of the kind described in the following sentence, such Holder shall not dispose of, sell or offer for sale the Registrable Securities pursuant to the Registration Statement until such Holder receives (i) copies of the supplemented or amended Prospectus, or until counsel for the Company shall have determined that such disclosure is not required due to subsequent events, (ii) notice in writing (the "Advice") from the Company that the use of the Prospectus may be resumed and (iii) copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. Pursuant to the immediately preceding sentence, the Company may provide such Notice to the Holder upon the determination by the Company of the existence of any fact or the happening or any event that makes any statement of a material fact made in the Registration Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue in any material respect, or that requires the making of any additions to or changes in the Registration Statement or the Prospectus, in order to make the statements therein not misleading in any material respect. If so directed by the Company in connection with any such notice, each Holder will deliver to the Company (at the Company's expense) all copies, other than permanent file copies then in such Holder's possession, of the Prospectus covering such Registrable Securities that was current immediately prior to the time of receipt of such notice. In the event the Company shall give any such Blocking Notice or Notice, the time regarding the effectiveness of such Registration Statement set forth in Section 5(a) and the final exercise date of the Warrant shall be extended by one and one-half (1-1/2) times the number of days during the period from and including the date of the giving of such Blocking Notice or Notice to and including the date when the Holder shall have received the copies of the supplemented or amended Prospectus, the Advice and any additional or supplemental filings that are incorporated by reference in the Prospectus. Delivery of a Blocking Notice or Notice and the related suspension of any Registration Statement shall not constitute a default under this Agreement and shall not create any obligation to pay liquidated damages under Section 2 hereof. However, if the Holder's ability to sell under the Registration Statement is suspended for more than the 60 day periods described above (an "Excess Blocking Period"), then the Company shall pay to the Investor two percent (2%) of the Outstanding Amount of the Warrants for each 30 day period commencing on the first day of the thirty (30) day period (or part thereof) following the beginning of an Excess Blocking Period until the Excess Blocking Period terminates. Such payment will be payable at the option of the Company made upon irrevocable notice to the Investor not later than the first day following the beginning of a Excess Blocking Period, either in cash or in Shares valued at the average of the high and low trading prices of the Shares on the Nasdaq Small Cap Market (or the Nasdaq National Market if the Shares are included therein) for each of the five trading days immediately preceding the first day following the beginning of the Excess Blocking Period, in each case within five (5) business days of the end of each 30 day period. In addition, if the Excess Blocking Period continues for more than an aggregate of 180 days in any 360-day period, or the payment is not made within 5 business days of the end of each 30 day period, then at Holder's option, the Company shall redeem Holder's Warrants at a redemption price equal to 125% of the Outstanding Amount of the Warrants together with all payments due under this paragraph and under the Warrant and the Agreement. 6. Indemnification. (a) Company Indemnity. The Company will indemnify the Holder, each of its officers, directors and partners, and each person controlling Holder, within the meaning of Section 15 of the Securities Act and the rules and regulations thereunder with respect to which registration, qualification or compliance has been effected pursuant to this Agreement, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular or other document (including any related registration statement, notification or the like) incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or any state securities law or, in either case, any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse the Holder, each of its officers, directors and partners, and each person controlling such Holder, for any legal and any other expenses reasonably incurred in connection with investigating and defending any such claim, loss, damage, liability or action, provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission (or alleged untrue statement or omission) that is made in reliance upon and in conformity with written information furnished to the Company by the Holder and stated to be specifically for use therein. In addition to any other information furnished in writing to the Company by the Holder, the information in the Registration Statement concerning the Holder under the captions "Selling Shareholders" (or any similarly captioned section containing the information required pursuant to Item 507 of Regulation S-K promulgated pursuant to the Securities Act) and "Plan of Distribution" (or any similarly captioned section containing information required pursuant to Item 508 of Regulation S-K) shall be deemed information furnished in writing to the Company by the Holder to the extent it conforms to information actually supplied in writing by the Holder. The indemnity agreement contained in this Section 6(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent will not be unreasonably withheld). (b) Holder Indemnity. The Holder will, if Registrable Securities held by it are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, each of its directors, officers, partners, each person who controls the Company within the meaning of Section 15 of the Securities Act and the rules and regulations thereunder, each other Holder (if any), and each of their officers, directors and partners, and each person controlling such other Holder against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statement therein not misleading, and will reimburse the Company and such other Holders and their directors, officers and partners, or control persons for any legal or any other expenses reasonably incurred in connection with investigating and defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus or other document in reliance upon and in conformity with written information furnished to the Company by the Holder and stated to be specifically for use therein, and provided that no Holder shall be liable under this indemnity for an amount in excess of the proceeds received by the Holder from the sale of the Registrable Securities pursuant to such registration statement. In addition to any other information furnished in writing to the Company by the Holder, the information in the Registration Statement concerning the Holder under the captions "Selling Shareholders" (or any similarly captioned section containing the information required pursuant to Item 507 of Regulation S-K promulgated pursuant to the Securities Act) and "Plan of Distribution" (or any similarly captioned section containing information required pursuant to Item 508 of Regulation S-K) shall be deemed information furnished in writing to the Company by the Holder to the extent it conforms to information actually supplied in writing by the Holder. The indemnity agreement contained in this Section 6(b) shall not apply to amounts paid in settlement of any such claims, losses, damages or liabilities if such settlement is effected without the consent of the Holder (which consent shall not be unreasonably withheld). (c) Procedure. Each party entitled to indemnification under this Article (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim in any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld), and the Indemnified Party may participate in such defense at such party's expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Article except to the extent that the Indemnifying Party is materially and adversely affected by such failure to provide notice. The Indemnifying Party shall not, in connection with any one such action or proceeding or separate but substantially similar or related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for such Indemnified Party, provided, however, that if separate firm(s) of attorneys are required due to a conflict of interest, then the Indemnifying Party shall be liable for the reasonable fees and expenses of each such separate firm. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with the defense of such claim and litigation resulting therefrom. 7. Contribution. If the indemnification provided for in Section 6 herein is unavailable to the Indemnified Parties in respect of any losses, claims, damages or liabilities referred to herein (other than by reason of the exceptions provided therein), then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of the Company and of the Holder in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Holder on the other shall be deemed to be in the same proportion as the proceeds from the offering (net of discounts and commissions but before deducting expenses) received by the Company from the initial sale of the Registrable Securities by the Company to the Holder pursuant to this Registration Rights Agreement bear to the proceeds received by the Holder from the sale of Registrable Securities pursuant to the registration statement. The relative fault of the Company on the one hand and of the Holder, on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, by the Holder or by the underwriters. In no event shall the obligation of any Indemnifying Party to contribute under this Section 7 exceed the amount that such Indemnifying Party would have been obligated to pay by way of indemnification if the indemnification provided for under Sections 6(a) or 6(b) hereof had been available under the circumstances. The Company and the Holder agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraphs. The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraphs shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section, no Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities offered by such Holder and distributed to the public, or offered to the public, exceed the amount paid by such Holder for the underlying Warrants converted into such shares of Common Stock. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 8. Survival. The indemnity and contribution agreements contained in Sections 6 and 7 and the representations and warranties of the Company contained herein shall remain operative and in full force and effect regardless of (i) any termination of the Agreement or any underwriting agreement, (ii) any investigation made by or on behalf of any Indemnified Party or by or on behalf of the Company and (iii) the consummation of the sale or successive resales of the Registrable Securities. 9. Information by Holder. The Holder shall promptly furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Agreement. All information provided to the Company by the Holder shall be accurate and complete in all material respects and the Holder shall promptly notify the Company if any such information becomes incorrect or incomplete. If the Holder does not timely provide all such reasonably requested information, the Holder shall not be entitled to the liquidated damages contemplated by paragraph 2(b)(ii) to the extent that such delay in the Registration Statement becoming effective is caused by such failure to timely provide information unless such Holder shall be able to demonstrate to the Company's reasonable satisfaction that such failure to timely provide did not proportionately contribute to the event giving rise to the indemnity obligation. 10. Transfer or Assignment of Registration Rights. The rights granted to the Purchaser by the Company under this Registration Rights Agreement to cause the Company to register Registrable Securities may be transferred or assigned to a transferee or assignee of not less than $500,000 in Outstanding Amount of the Warrants or any permitted transferee or assignee of the Warrants, provided that the Company is given written notice by the Holder at the time of or within a reasonable time after said transfer or assignment, stating the name and address of said transferee or assignee and identifying the securities with respect to which such registration rights are being transferred or assigned; and provided that the transferee or assignee of such rights agrees to be bound by this Registration Rights Agreement. 11. Miscellaneous. (a) Entire Agreement. This Registration Rights Agreement contains the entire understanding and agreement of the parties, and may not be modified or terminated except by a written agreement signed by both parties. (b) Notices. Any notice or other communication given or permitted under this Agreement shall be in writing and shall be deemed to have been duly given if personally delivered or sent by registered or certified mail, return receipt requested, postage prepaid or by air courier, (a) if to Purchaser, at its address set forth in the Warrants, (b) if to the Company, to Research Frontiers Incorporated, at its address hereinabove set forth, and (c) if to a Holder other than Purchaser, at the address thereof furnished by like notice to the Company, or (d) to any such addresses at such other address or addresses as shall be so furnished to the other parties by like notice. (c) Gender of Terms. All terms used herein shall be deemed to include the feminine and the neuter, and the singular and the plural, as the context requires. (d) Governing Law, Consent of Jurisdiction; Waiver of Tax-Trial. This Registration Rights Agreement and the validity and performance of the terms hereof shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflicts of law or choice of law, except to the extent that the law of Delaware regulates the Company's issuance of securities. The parties hereto hereby agree that all actions or proceedings arising directly or indirectly from or in connection with this Registration Rights Agreement shall be litigated only in the Supreme Court of the State of New York or the United States District Court for the Southern District of New York located in New York County, New York. To the extent permitted by applicable law, the parties hereto consent to the jurisdiction and venue of the foregoing courts and consent that any process or notice of motion or other application to either of said courts or a judge thereof may be served inside or outside the State of New York or the Southern District of New York by registered mail, return receipt requested, directed to the such party at its address set forth in this Registration Rights Agreement (and service so made shall be deemed complete five (5) days after the same has been posted as aforesaid) or by personal service or in such other manner as may be permissible under the rules of said courts. The parties hereto hereby waive any right to a jury trial in connection with any litigation arising out of this Registration Rights Agreement. (e) Limitation of Registration Rights. Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be required to include in any registration statement filed pursuant to this Agreement any Registrable Securities held by a Holder if, in the opinion of counsel to the Company concurred in by counsel to such Holder, all of such Registrable Securities may be sold by such Holder pursuant to Rule 144(k) under the Securities Act (or any successor rule) within a period of not more than 30 days from the date of such opinion. Titles. The titles used in this Registration Rights Agreement are used for convenience only and are not to be considered in construing or interpreting this Registration Rights Agreement. IN WITNESS WHEREOF, the parties hereto have caused this Registration Rights Agreement to be duly executed as of the date first above written. PURCHASERS RAMIUS CAPITAL GROUP, L.L.C.
