RAPTOR PHARMACEUTICAL CORP.

Raptor Pharmaceutical Corp., or Raptor, was initially incorporated in Nevada on July 29, 1997 as Axonyx Inc. In October 2006, Axonyx Inc. and its then wholly-owned subsidiary completed a reverse merger, business combination with TorreyPines Therapeutics, Inc., reincorporated in Delaware and changed its name to TorreyPines Therapeutics, Inc. In September 2009, we and our wholly-owned subsidiary completed a reverse merger, business combination with Raptor Pharmaceuticals Corp., pursuant to which Raptor Pharmaceuticals Corp. became our wholly-owned subsidiary. Immediately prior to the merger, we changed our corporate name from TorreyPines Therapeutics, Inc. to Raptor Pharmaceutical Corp. Raptor’s principal executive offices are located at 9 Commercial Blvd., Suite 200, Novato, CA 94949, and Raptor’s telephone number is (415) 382-8111. Raptor is a NASDAQ-listed development-stage biotechnology company dedicated to speeding the delivery of new treatment options to patients by working to improve existing therapeutics through the application of highly specialized drug targeting platforms and formulation expertise. Raptor focuses on underserved patient populations where it believes that it can have the greatest potential impact. Raptor is developing drug therapies for the potential treatment of: genetic diseases including nephropathic cystinosis, or cystinosis, and Huntington’s Disease, or HD; metabolic diseases including non-alcoholic steatohepatitis, or NASH, and aldehyde dehydrogenase, or ALDH2, deficiency, or Ethanol Intolerance; and liver diseases including primary liver cancer or hepatocellular carcinoma, or HCC, and hepatitis. Raptor is also researching a non-opioid solution designed to treat chronic pain and potentially thrombotic disorder.

We have not sought the consent of the sources to refer to their reports appearing or incorporated by reference in this prospectus.

RESALE OFFERING


Issuer:		Raptor Pharmaceutical Corp.

Selling Stockholders:		Selling stockholders of the Company named in this prospectus who purchased shares of common stock and warrants to purchase shares of common stock of Raptor Pharmaceuticals Corp., a Delaware corporation and our wholly-owned subsidiary, in private placements in August 2009 and May and June 2008, which such shares of common stock and warrants were subsequently exchanged for shares of our common stock and warrants to purchase shares of our common stock pursuant to the merger described under the heading “Raptor Pharmaceutical Corp.”

Securities offered by Selling Stockholders:		5,557,865 shares of our common stock, which includes 1,764,226 issuable to the selling stockholders named in this prospectus upon the exercise of warrants sold in the private placements described above.

Use of Proceeds:		The selling stockholders will receive all net proceeds from any resale of our common stock covered by this prospectus. We will not receive any proceeds from any such resale. Any proceeds we receive from the exercise of warrants to purchase the shares included in the shares that are being offered by the selling stockholders hereunder will be used to continue the development of our product candidates and to expand the development of our drug pipeline and for general working capital. See “Use of Proceeds” on page 5.

NASDAQ Ticker:		RPTP

USE OF PROCEEDS

All of our common stock covered by this prospectus is being sold by or for the account of the selling stockholders. We will receive no proceeds from the sale from time to time of our common stock by the selling stockholders. However, this prospectus covers the offer of shares of common stock issuable in the future upon the exercise of warrants to purchase up to an aggregate of 1,764,226 shares of our common stock, as described below under the heading “Selling Stockholders” in this prospectus, at the following exercise prices: two-year warrants to purchase up to 299,563 shares of our common stock are exercisable at $3.86 per share; two-year warrants to purchase up to 869,114 shares of our common stock are exercisable at $2.57 per share during the first year of issuance and $3.21 per share during the second year of issuance; five-year warrants to purchase up to 465,816 and 129,733 shares of our common stock are exercisable at $2.36 and $1.50 per share, respectively, but contain a cashless (net exercise) feature that allows the holders, under certain circumstances, to exercise such warrants without making any cash payment to us. If all of these warrants are exercised in full for cash during the second year of the warrant term, we would receive aggregate gross proceeds of approximately $5.2 million or $3.9 million excluding the warrants with the cashless (net exercise) feature. There can be no assurance any of these warrants will be exercised by the selling stockholders at all or that those warrants containing a cashless (net exercise) feature will be exercised for cash rather than pursuant to the cashless (net exercise) feature. We expect to use proceeds, if any, from exercise of these warrants for general corporate purposes, including, without limitation, development of our product candidates and expansion of our drug pipeline, capital expenditures, possible acquisitions, investments, and for any other corporate purposes that we may specify in any prospectus supplement. We cannot assure that any selling stockholder will sell any or all of the shares of common stock registered pursuant to the registration statement of which this prospectus is a part. The selling security holders will pay any brokerage commissions or similar charges incurred for the sale of such shares of our common stock.

DETERMINATION OF OFFERING PRICE

The selling stockholders will determine at what price they may sell our common stock covered by this prospectus, and such sales may be made at prevailing market prices, or at privately negotiated prices.

DILUTION

The common stock to be sold by the selling stockholders is common stock that is currently issued and outstanding or is issuable on exercise of warrants that have already been issued. Accordingly, there will be no dilution to our existing stockholders from the sale of any of the shares registered by this prospectus.

SELLING STOCKHOLDERS

On September 29, 2009, we completed our business combination with Raptor Pharmaceuticals Corp. in accordance with the terms of that certain Agreement and Plan of Merger and Reorganization, dated July 27, 2009, by and among us, ECP Acquisition, Inc. (“ECP”), our then-wholly-owned subsidiary, and Raptor Pharmaceuticals Corp., pursuant to which ECP merged with and into Raptor Pharmaceuticals Corp., with Raptor Pharmaceuticals Corp. continuing as the surviving corporation and a wholly-owned subsidiary of us. Immediately prior to the effective time of such merger and in connection therewith, we effected a 1-for-17 reverse stock split of our common stock and changed our corporate name to “Raptor Pharmaceutical Corp.”

During May and June 2008, prior to the merger described above, Raptor Pharmaceuticals Corp., issued an aggregate of 20,000,000 units of its securities, each unit comprised of one share of its common stock and one warrant to purchase one half of one share of its common stock, at a unit purchase price of $0.50 per unit, in a private placement with various accredited investors. The warrants, exercisable for two years from closing of such private placement, as initially issued, entitled such investors to purchase up to an aggregate of 10,000,000 shares of Raptor Pharmaceuticals Corp.’s common stock at an exercise price of $0.75 per share during the first year and $0.90 per share during the second year. In connection with this private placement, Raptor Pharmaceuticals Corp. issued placement agents warrants to purchase in the aggregate 2,100,000 shares of its common stock at an exercise price of $0.55 per share for a five year term and it paid to such placement agents cash fees totaling $700,000. Such placement agent warrants contain a cashless (net exercise) feature that allows its holders, under certain circumstances, to exercise such warrants without making any cash payment. Of the placement agents compensated, Limetree Capital was issued warrants to purchase 1,882,650 shares of Raptor Pharmaceuticals Corp.’s common stock and was paid cash commissions of $627,550. Erich Sager, one of our board members, serves on the board of directors of Limetree Capital and is a founding partner thereof. In connection with this private placement, Raptor Pharmaceuticals Corp. granted registration rights to the investors in the financing, pursuant to which it agreed to file a registration statement with the SEC covering the resale of the common stock and all shares of common stock issuable upon the exercise of the warrants no later than 60 days following the initial closing of such financing and agreed to use its commercially reasonable efforts to keep such registration continuously effective, with certain exceptions, with respect to a given investor until the earlier of the following: (i) the second anniversary of the closing date of such financing, (ii) the date all the purchased securities held by such investor in such financing may be sold under Rule 144 during any 90-day period and (iii) such time as all of the purchased securities held by such investor have been publicly sold. Pursuant to the terms of the purchase agreement governing such private placement, Raptor Pharmaceuticals Corp. may require an investor party thereto to suspend the sales of the securities held by the investor pursuant to such purchase agreement and covered by a given prospectus upon the occurrence of any event that makes any statement in such prospectus or the related registration statement of which it forms a part untrue in any material respect or that requires the changing of statements in such documents in order to make statements in such documents not misleading.

In July 2009, prior to the merger described above, Raptor Pharmaceuticals Corp. closed a warrant exchange offer with those investor-warrant holders who were holders of the warrants to purchase its common stock issued in connection with its May and June 2008 private placement, as described above, of the right to exchange such warrants and subscribe for new warrants to purchase shares of the Raptor Pharmaceuticals Corp.’s common stock at an exercise price of $0.30 per share (to the extent such new warrants were exercised (in whole or in part) on or before July 17, 2009). Pursuant to such warrant exchange, new warrants were exercised for an aggregate amount of 8,715,000 shares of Raptor Pharmaceuticals Corp.’s common stock which resulted in aggregate proceeds to Raptor Pharmaceuticals Corp. of $2,614,500.

In August 2009, prior to the merger described above, Raptor Pharmaceuticals Corp., issued an aggregate of 7,456,250 units of its securities, each unit comprised of one share of its common stock and one warrant to purchase one half of one share of its common stock, at a unit purchase price of $0.32 per unit, in a private placement with various accredited investors. The warrants, exercisable for two years from closing of such private placement, as initially issued, entitled such investors to purchase up to an aggregate of 3,728,125 shares of Raptor Pharmaceuticals Corp.’s common stock at an exercise price of $0.60 per share during the first year and $0.75 per share during the second year. In connection with this private placement, Raptor Pharmaceuticals Corp. issued Limetree Capital, the placement agent in such private placement, warrants to purchase in the aggregate 556,500 shares of its common stock at an exercise price of $0.35 per share for a five year term and it paid to such placement agent cash fees totaling $59,360. Such placement agent warrants contain a cashless (net exercise) feature that allows its holders, under certain circumstances, to exercise such warrants without making any cash payment. In connection with this private placement, Raptor Pharmaceuticals Corp. granted registration rights to the investors in the financing, pursuant to which it agreed to file a registration statement with the SEC covering the resale of the common stock and all shares of common stock issuable upon the exercise of the warrants no later than 75 days following the initial closing of such financing. Pursuant to the terms of the purchase agreement governing such private placement, Raptor Pharmaceuticals Corp. may require an investor party thereto to suspend the sales of the securities held by the investor pursuant to such purchase agreement and covered by a given prospectus upon the occurrence of any event that makes any statement in such prospectus or the related registration statement of which it forms a part untrue in any material respect or that requires the changing of statements in such documents in order to make statements in such documents not misleading.

As a result of the merger and in accordance with the Agreement and Plan of Merger and Reorganization, (i) the 20,000,000 shares of Raptor Pharmaceuticals Corp.’s common stock issued in the 2008 private placement, the 8,715,000 shares of Raptor Pharmaceuticals Corp.’s common stock issued as a result of the warrant exchange, and the 7,456,250 shares of Raptor Pharmaceuticals Corp.’s common stock issued in the 2009 private placement, were converted into the right to receive an aggregate of 8,432,364 shares of our common stock, (ii) the warrants issued in the 2008 private placement to investors to purchase 10,000,000 shares of Raptor Pharmaceuticals Corp.’s common stock at exercise prices of $0.75 and $0.90 per share, depending on when exercised, which, after the warrant exchange, were reduced to warrants to purchase 1,285,000 shares of Raptor Pharmaceuticals Corp.’s common stock, and the warrants issued in the 2009 private placement to investors to purchase 3,728,125 shares of Raptor Pharmaceuticals Corp.’s common stock at exercise prices of $0.60 and $0.75 per share, depending on when exercised, were converted into the right to receive warrants to purchase 299,563 shares of our common stock at exercise prices of $3.21 and $3.86 per share, depending on when exercised, and warrants to purchase 869,114 shares of our common stock at exercise prices of $2.57 and $3.21 per share, depending on when exercised, respectively, and (iii) the warrants issued in the 2008 private placement to such placement agents to purchase 2,100,000 shares of Raptor Pharmaceuticals Corp.’s common stock at an exercise price of $0.55 per share (after the exercise by a certain placement agent of a warrant to purchase 101,850 shares of Raptor Pharmaceuticals Corp.’s common stock but prior to the effective time of the merger), and the warrants issued in the 2009 private placement to such placement agent to purchase 556,500 shares of Raptor Pharmaceuticals Corp.’s common stock at an exercise price of $0.35 per share, were converted into the right to receive warrants to purchase 465,816 shares of our common stock at an exercise price of $2.36, 23,744 shares of our common stock, and warrants to purchase 129,733 shares of our common stock at an exercise price of $1.50, respectively. Other than as described herein, none of the other provisions of such warrants were changed, including, with respect to the placement agent warrants, the cashless (net exercise) feature.

We have included in this prospectus and related registration statement certain of the common stock (including common stock issuable upon exercise of warrants) issued in the private placements described above to the selling stockholders. The term “selling stockholder” includes the stockholders listed below and their transferees, pledgees, donees or other successors in interest selling shares received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other non-sale related transfer. Information concerning the selling stockholders may change after the date of this prospectus and changed information will be presented in a supplement to this prospectus if and when required.

The following table sets forth to our knowledge as of October 6, 2009:

	•		the name of each of the selling stockholders;

	•		the number of shares of our common stock beneficially owned (as determined in accordance with the rules of the SEC) by each selling stockholder prior to this offering;

	•		the percentage (if one percent or more) of our common stock owned by each such selling stockholder prior to this offering;

	•		the number of outstanding shares of our common stock being offered by each such selling stockholder pursuant to this prospectus;

	•		the number of shares of our common stock issuable upon exercise by each such selling stockholder of the warrants being offered pursuant to this prospectus;

	•		the number of shares of our common stock beneficially owned (as determined in accordance with the rules of the SEC) by each such selling stockholder upon completion of this offering; and

	•		the percentage (if one percent or more) of common stock owned by each such selling stockholder upon completion of this offering.

The information in the table below was prepared based solely on information supplied to us by or on behalf of the selling stockholders, and we have not independently verified such information. The aggregate number of shares of common stock in the columns “Number of Outstanding Shares Being Offered” and “Shares Issuable Upon Exercise of Warrants Being Offered” represents the total shares of common stock that a selling stockholder may offer under this prospectus. Each selling stockholder may offer and sell, from time to time, some, all or none of its shares included in this prospectus. The number of shares in the column “Shares of Common Stock Beneficially Owned After Offering” assumes that the selling stockholder sells all of the shares covered by this prospectus as we have assumed for purposes of such table that none of the shares covered by this prospectus will be held by the selling stockholders after the completion of their resales.

We do not know how long the selling stockholder will hold such shares before selling them, and we currently have no agreements, arrangements or understandings with the selling security holders regarding the sale of any of the shares. Because the selling stockholders may offer all or only some portion of the 5,557,865 shares of common stock to be registered, no estimate can be given as to the amount or percentage of these shares of common stock that will be held by the selling stockholders upon termination of their resales. The selling stockholders may have sold or transferred, in transactions exempt from the registration requirements of the

Securities Act, some or all of such shares since the date on which the information in the table is presented. Information about the selling security holders may change over time.

Except as noted in the footnotes to the table below, to our knowledge, none of the selling stockholders has held any position or office or had any other material relationship with us or any of our predecessors or affiliates within the past three years other than as a result of the ownership of our securities. We may amend or supplement this prospectus from time to time to update the disclosure set forth in it.

PLAN OF DISTRIBUTION

Each selling stockholder of the common stock and any of their transferees, pledgees, donees or other successors in interest may, from time to time, sell any or all of their shares of common stock on NASDAQ or any other stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. A selling stockholder may use any one or more of the following methods when selling shares:

•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•

block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•

an exchange distribution in accordance with the rules of the applicable exchange;

•

privately negotiated transactions;

•

settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;

•

broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

•

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•

a combination of any such methods of sale; or

•

any other method permitted pursuant to applicable law.

The selling stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus. Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with NASDR Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with NASDR IM–2440. In connection with the sale of the common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of the common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or

other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

Pursuant to the terms of the purchase agreement governing the private placements described under the heading “Selling Stockholders” in this prospectus, Raptor Pharmaceuticals Corp. agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act, and agreed to keep a prospectus effective with respect to the common stock issued or issuable pursuant to the 2008 private placement until the earlier of the following: (i) the second anniversary of the closing date of such financing, (ii) the date all the purchased securities held by such investor in such financing may be sold under Rule 144 during any 90-day period and (iii) such time as all of the purchased securities held by such investor have been publicly sold. The shares will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Because selling stockholders may be deemed to be “underwriters” within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act including Rule 172 thereunder. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this prospectus. There is no underwriter or coordinating broker acting in connection with the proposed sale of the shares by the selling stockholders.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the shares may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of shares of the common stock by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

DESCRIPTION OF OUR CAPITAL STOCK

Authorized and Outstanding Capital Stock

Under our certificate of incorporation, as amended, our authorized capital stock consists of 150,000,000 shares of common stock, par value $0.001 per share and 15,000,000 shares of preferred stock, par value $0.001 per share. As of October 6, 2009, there were 18,822,421 shares of common stock outstanding, 3,321,916 shares of common stock reserved for issuance upon exercise of outstanding stock options and warrants to purchase common stock, and no shares of preferred stock outstanding.

The following summary description of our capital stock is based on the applicable provisions of the Delaware General Corporation Law, or DGCL, and on the provisions of our certificate of incorporation, as amended, and our bylaws, as amended. This information is qualified entirely by reference to the applicable provisions of the Delaware General Corporation Law and our certificate of incorporation, as amended, and our bylaws, as amended. For information on how to obtain copies of such documents, please refer to the heading “Where You Can Find More Information” in this prospectus.

Common Stock

Dividend Rights

Dividends from our capital stock, subject to the provisions of our certificate of incorporation, as amended, and applicable law, if any, may be declared by our board of directors pursuant to law at any regular or annual meeting. Dividends may be paid in cash, in property, or in shares of the capital stock, subject to the provisions of the certificate of incorporation, as amended, and applicable law.

Voting Rights

For the purpose of determining those stockholders entitled to vote at any meeting of our stockholders, except as otherwise provided by law, only persons in whose names stand on the stock records of the corporation on the record date, as provided in Section 12 of our bylaws, as amended, shall be entitled to vote at any meeting of stockholders. Every person entitled to vote shall have the right to do so either in person, by remote communication, if applicable, or by an agent or agents authorized by a proxy granted in accordance with Delaware law. An agent so appointed need not be a stockholder. No proxy shall be voted after three (3) years from its

date of creation unless the proxy provides for a longer period. Each share of our common stock has identical rights and privileges in every respect.

Our bylaws, as amended, provide that holders of shares of our common stock have the power to adopt, amend or repeal the bylaws of the corporation; provided, that in addition to any vote of the holders of any class or series of stock of the corporation required by law or by our certificate of incorporation, as amended, such action by stockholders shall require the affirmative vote of the holders of at least 66-2/3% of the voting power of all of the then-outstanding shares of our capital stock entitled to vote generally in the election of directors, voting together as a single class. In addition, our certificate of incorporation, as amended, and bylaws, as amended, provide that a director may be removed at any time without cause by the affirmative vote of the holders of 66-2/3% of all of our then-outstanding shares of voting stock entitled to vote at an election of directors.

No Preemptive or Similar Rights

Our common stock is not entitled to preemptive rights and is not subject to conversion or redemption.

Right to Receive Liquidation Distributions

If we voluntarily or involuntarily liquidate, dissolve or wind-up, the holders of our common stock will be entitled to receive after distribution in full of the preferential amounts, if any, to be distributed to the holders of preferred stock or any series of preferred stock, all of the remaining assets available for distribution ratably in proportion to the number of shares of our common stock held by them. Holders of our common stock have no preferences or any preemptive conversion or exchange rights. Our outstanding common stock is fully paid and non-assessable. The rights, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock, which our board of directors may designate and issue in the future.

Anti-Takeover Provisions

Under the provisions of the DGCL, our certificate of incorporation, as amended, and bylaws, as amended, may have the effect of delaying, deferring, or discouraging another person from acquiring control of us. Such provisions could limit the price that some investors might be willing to pay in the future for our common stock. These provisions of the DGCL and our certificate of incorporation, as amended, and bylaws, as amended, may also have the effect of discouraging or preventing certain types of transactions involving an actual or threatened change of control of us, including unsolicited takeover attempts, even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price.

We are subject to Section 203 of the DGCL, which, subject to certain exceptions, prohibits a Delaware corporation from engaging in any “business combination” with an “interested stockholder” for a period of three years following the time that such stockholder became an interested stockholder, unless:

•

the board of directors of the corporation approves either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder, prior to the time the interested stockholder attained that status;

•

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

•

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

With certain exceptions, an “interested stockholder” is a person or group who or which owns 15% or more of the corporation’s outstanding voting stock (including any rights to acquire stock pursuant to an option, warrant, agreement, arrangement or understanding, or upon the exercise of conversion or exchange rights, and stock with respect to which the person has voting rights only), or is an affiliate or associate of the corporation and was the owner of 15% or more of such voting stock at any time within the previous three years.

In general, Section 203 defines a business combination to include:

•

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

•

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

•

subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

•

any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or

•

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

A Delaware corporation may “opt out” of this provision with an express provision in its original certificate of incorporation or an express provision in its amended and restated certificate of incorporation or bylaws resulting from a stockholders’ amendment approved by at least a majority of the outstanding voting shares. However, we have not “opted out” of this provision. Section 203 could prohibit or delay mergers or other takeover or change-in-control attempts and, accordingly, may discourage attempts to acquire us.

Our certificate of incorporation, as amended, and bylaws, as amended, provide that its board will have one class of directors serving concurrent, one-year terms. Subject to the rights of the holders of any outstanding series of our preferred stock, our certificate of incorporation, as amended, authorizes only our board of directors to fill vacancies, including newly created directorships. Accordingly, this provision could prevent a stockholder from obtaining majority representation on the board of directors by enlarging the board of directors and filling the new directorships with its own nominees. Our certificate of incorporation, as amended, also provides that directors may be removed by stockholders for cause by the affirmative vote of the holders of a majority of the outstanding shares of voting stock or without cause by the affirmative vote of the holders of 66-2/3% of the outstanding shares of voting stock.

Our certificate of incorporation, as amended, also provides that stockholders may not take action by written consent, but may only take action at duly called annual or special meetings of stockholders. Our certificate of incorporation, as amended, further provides that special meetings of our stockholders may be called only by the chairman of the board of directors, the chief executive officer or a majority of the board of directors. This limitation on the right of stockholders to call a special meeting could make it more difficult for stockholders to initiate actions that are opposed by our board of directors. These actions could include the removal of an incumbent director or the election of a stockholder nominee as a director. They could also include the implementation of a rule requiring stockholder ratification of specific defensive strategies that have been adopted by our board of directors with respect to unsolicited takeover bids. In addition, the limited ability of our stockholders to call a special meeting of stockholders may make it more difficult to change the existing board and management.

Our bylaws, as amended, provide that stockholders seeking to bring business before an annual meeting of stockholders, or to nominate candidates for election as directors at an annual meeting of stockholders, must provide timely notice thereof in writing. To be timely, a stockholder’s notice must be delivered to or mailed and received at our principal executive offices not less than 120 days prior to the date of our annual meeting. Our bylaws, as amended, also specify certain requirements as to the form and content of a stockholder’s notice. These provisions may preclude stockholders from bringing matters before an annual meeting of stockholders or from making nominations for directors at an annual meeting of stockholders.

The authorized but unissued shares of our common stock and preferred stock are available for future issuance without stockholder approval. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions, employee benefit plans and “poison pill” rights plans. This could result in our management being able to issue more shares without further stockholder approval and could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Transfer Agent

The transfer agent for our common stock is American Stock Transfer & Trust Company.

Listing

Our common stock is listed on the NASDAQ Capital Market under the symbol “RPTP.”

Preferred Stock

Our board of directors is authorized to provide for the issuance of shares of preferred stock in one or more series, and to fix for each series voting rights, if any, designations, preferences and relative, participating, optional or other special rights and such qualifications, limitations or restrictions as provided in a resolution or resolutions adopted by our board of directors. Our board of directors has authorized the issuance of Series A participating preferred stock which includes terms and conditions which could discourage a takeover or other transaction that holders of some or a majority of common stock might believe to be in their best interests. In addition, our board of directors may authorize the issuance of preferred stock in which holders of preferred stock might receive a premium for their shares over the then market price. We have no present plans to issue any shares of preferred stock.

Series A Participating Preferred Stock

Each outstanding share of our common stock has attached to it one preferred share purchase right that entitles the registered holder to purchase from us a unit of one one-thousandth of a share of its Series A participating preferred stock, which is referred to herein as the Junior Preferred Stock, at a price of $15.00 per unit. The description and terms of the rights are set forth in a rights agreement dated as of May 13, 2005, as amended, by and between American Stock Transfer & Trust Company, as rights agent, and us, which is referred to herein as the Raptor Rights Agreement.

Subject to certain exceptions, until the earlier to occur of (i) the close of business on the tenth day after a public announcement that a person or group of affiliated or associated persons has acquired beneficial ownership of 15% or more of our outstanding common stock, subject to certain exceptions, or (ii) 10 business days (or such later date as may be determined by action of our board of directors prior to such time as any person becomes an acquiring person) following the commencement of, or announcement of an intention to make, a tender offer or exchange offer the consummation of which would result in the beneficial ownership by a person or group of 15% or more of such outstanding common stock (the earlier of such dates is the distribution date), the rights will be evidenced by our common stock certificates.

The Raptor Rights Agreement provides that, until the distribution date, the rights will be transferred with and only with our common stock. Until the distribution date (or earlier redemption or expiration of the rights), our common stock certificates, upon transfer or new issuance of common stock will contain a notation incorporating the Raptor Rights Agreement by reference. Until the distribution date (or earlier redemption or expiration of the rights), the surrender for transfer of any certificates of our common stock will also constitute the transfer of the rights associated with the common stock represented by such certificate. As soon as practicable following the distribution date, if any, separate certificates evidencing the rights will be mailed to holders of record of our common stock as of the close of business on the distribution date and such separate rights certificates alone will evidence the rights.

The rights are not exercisable until the distribution date. The rights will expire at the close of business on May 15, 2015 unless that final expiration date is extended or unless the rights are earlier redeemed or exchanged by us, in each case as described below.

The purchase price payable, and the number of units of Junior Preferred Stock or other securities or property issuable, upon exercise of the rights are subject to adjustment from time to time to prevent dilution (a) in the event of a stock dividend on, or a subdivision, combination or reclassification of, the Junior Preferred Stock, (b) upon the grant to holders of the units of Junior Preferred Stock of certain rights or warrants to subscribe for or purchase units of Junior Preferred Stock at a price, or securities convertible into units of Junior Preferred Stock with a conversion price, less than the then current market price of the units of Junior Preferred Stock, or (c) upon the distribution to holders of the units of Junior Preferred Stock of evidences of indebtedness or assets (excluding regular periodic cash dividends paid out of earnings or retained earnings or dividends payable in units of Junior Preferred Stock) or of subscription rights or warrants other than those referred to above.

The number of outstanding rights and the number of units of Junior Preferred Stock issuable upon exercise of each right are also subject to adjustment in the event of a stock split of our common stock or a stock dividend on the common stock payable in common stock or subdivisions, consolidations or combinations of the common stock occurring, in any such case, prior to the distribution date.

The Junior Preferred Stock purchasable upon exercise of the rights will not be redeemable. Each share of Junior Preferred Stock will be entitled to an aggregate dividend of 1,000 times the dividend declared per share of our common stock. In the event of liquidation, the holders of the shares of Junior Preferred Stock will be entitled to an aggregate payment of 1,000 times the payment made per share of our common stock. Each share of Junior Preferred Stock will have 1,000 votes, voting together with our common stock. Finally, in the event of any merger, consolidation or other transaction in which shares of our common stock are exchanged, each share of Junior Preferred Stock will be exchanged or changed in an amount per share equal to 1,000 times the amount received per share of common stock. These rights are protected by customary anti-dilution provisions.

Because of the nature of the dividend, liquidation and voting rights, the value of each unit of Junior Preferred Stock purchasable upon exercise of each right should approximate the value of one share of common stock.

If, after the rights become exercisable, we are acquired in a merger or other business combination transaction with an acquiring person or one of its affiliates, or 50% or more of our consolidated assets or earning power are sold to an acquiring person or one of its affiliates, proper provision will be made so that each holder of a right will thereafter have the right to receive, upon exercise thereof at the then current exercise price of the right, that number of shares of common stock of the acquiring company which at the time of such transaction will have a market value of two times the exercise price of the right.

If any person or group of affiliated or associated persons becomes the beneficial owner of 15% or more of the outstanding shares of our common stock, subject to certain exceptions, proper provision will be made so that each holder of a right, other than rights beneficially owned by the acquiring person (which will thereafter be unexercisable), will have the right to receive upon exercise that number of shares of our common stock or units of Junior Preferred Stock (or cash, other securities or property) having a market value of two times the exercise price of the right.

At any time after the acquisition by a person or group of affiliated or associated persons of beneficial ownership of 15% or more of the outstanding shares of our common stock, subject to certain exceptions, and prior to the acquisition by such person or group of 50% or more of the outstanding common stock, our board of directors may exchange the rights (other than rights owned by such person or group which have become void), in whole or in part, at an exchange ratio per unit of Junior Preferred Stock equal to the purchase price divided by the then current market price per unit of Junior Preferred Stock on the earlier of (i) the date on which any person becomes an acquiring person and (ii) the date on which a tender or exchange offer is announced which, if consummated would result in the offerer being the beneficial owner of 15% or more of the shares of our common stock then outstanding.

With certain exceptions, no adjustment in the purchase price will be required until cumulative adjustments require an adjustment of at least 1% in the purchase price. No fractional shares of Junior Preferred Stock will be issued (other than fractions which are integral multiples of one one-thousandth of a share of Junior Preferred Stock, which may, at our election, be evidenced by depositary receipts) and, in lieu thereof, an adjustment in cash will be made based on the market price of the units of Junior Preferred Stock on the last trading day prior to the date of exercise.

At any time on or prior to the earlier of (i) the close of business on the tenth day after a public announcement that a person or group of affiliated or associated persons acquires beneficial ownership of 15% or more of the outstanding our common stock (unless the board of directors extends the ten day period) or (ii) the tenth business day after a person commences, or announces its intention to commence, a tender offer or exchange offer that would result in the bidder’s beneficial ownership of 15% or more of the shares of our common stock, our board of directors may redeem the rights in whole, but not in part, at a price of $0.01 per right. The redemption of the rights may be made effective at such time, on such basis and with such conditions as our board of directors in its sole discretion may establish. Immediately upon any redemption of the rights, the right to exercise the rights will terminate and the only right of the holders of rights will receive the redemption price. The rights are also redeemable under other circumstances as specified in the Raptor Rights Agreement.

The terms of the rights may be amended by our board of directors without the consent of the holders of the rights except that from and after such time that there is an acquiring person no amendment may adversely affect the interests of the holders of the rights.

Until a right is exercised, the holder of a right will have no rights by virtue of ownership as our stockholder, other than those accruing as a result of the holder’s ownership in our common stock, including, without limitation, the right to vote or to receive dividends.

The rights have certain anti-takeover effects. The rights will cause substantial dilution to a person or group that attempts to acquire us on terms not approved by our board of directors, except pursuant to an offer conditioned on a substantial number of rights being acquired. The rights should not interfere with any merger or other business combination approved by our board of directors since the rights may be redeemed by us at the redemption price prior to the occurrence of a distribution date. The foregoing description of the rights is qualified in its entirety by reference to the Raptor Rights Agreement.
