PART II


ITEM 3.


The SEC allows us to “incorporate by reference” the information we file with them, which means that we can disclose important information to you by referring you to those documents.  The information incorporated by reference is an important part of this registration statement, and information that we file later with the SEC will automatically update and supersede this information.  We incorporate by reference in this registration statement the documents listed below and any future filings made with the SEC since the end of the fiscal year covered by the annual report referred to below under Sections 13(a) or 15(d) of the Securities Exchange Act of 1934.


(a)  The Company’s Annual Report on Form 20-F for its fiscal year ended March 31, 2005 filed September 12, 2005 (Commission File No. 0-30314), as amended;


(b)  All other reports filed by the Company with the SEC pursuant to Sections 13(a) or 15(d) of the Securities Exchange Act of 1934 subsequent to March 31, 2005; and


(c)  The description of the Company’s Common Stock contained in the Company’s Registration Statement on Form 20-F, as amended, as filed on August 1, 2000.


All documents subsequently filed by us pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, prior to the filing of a post-effective amendment which indicates that all securities offered have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference in this Registration Statement and to be part hereof from the date of filing such documents.


ITEM 4.  DESCRIPTION OF SECURITIES.


Not Applicable.



ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.



Not Applicable.



ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.


Under the Business Corporations Act (Ontario) (the “Act”), the Company may indemnify a present or former director or officer or a person who acts or acted at the Company’s request as a director or officer or of another corporation of which the Company is or was a shareholder or creditor, and his heirs and legal representatives, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by him in respect of any civil, criminal or administrative action or proceeding to which he is made a party by reason of being or having been such a director or officer if the director or officer acted honestly and in good faith with a view to the best interest of the Company and, in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, had reasonable grounds for believing that his conduct was lawful.  A director or officer is entitled to indemnification from the Company as a matter of right in respects of all costs, charges and expenses reasonably incurred by him in connection with the defense of any civil, criminal or administrative proceeding to which he is a party by reason of being or having been a director or officer of such corporation if he was substantially successful on the merits and fulfilled the conditions set forth above.


The by-laws of the Company provide that each director, each officer, each former director, each former officer and each person who acts or acted at the Company’s request as a director or officer or of a body corporate of which the Company is or was a shareholder or creditor, and his heirs and legal representatives, shall be indemnified and saved harmless by the Company from and against all costs, charges and expenses, including without limitation, each amount paid to settle an action or satisfy a judgment, reasonably incurred by him in respect of any civil, criminal or administrative action or proceeding to which his is made a party by reason or being or having been a director or officer of the Company or such body corporation, if he acted honestly and in good faith with a view to the Company’s best interest and in the case of a criminal or administrative action or proceeding that is enforced by a monetary pena lty he had reasonable grounds for believing his conduct was lawful.  In certain circumstances the Company has provided its Directors or its subsidiaries’ Directors with a written indemnification confirming the indemnification available under its by-laws.


The Company currently does not maintain directors’ and officers’ liability insurance.


Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended may be permitted to directors, officers or persons controlling the Company pursuant to the foregoing provisions, the Company has been informed that, in the opinion of the U.S. Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act of 1933, as amended and is therefore unenforceable.

ITEM 9.  UNDERTAKINGS.


1.  The undersigned registrant hereby undertakes:


(a)  To file, during the period in which offers or sales are being made, a post-effective amendment to this registration statement:


(i)  To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;


(ii)  To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement.  Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and


(iii)  To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;


Provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the issuer pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference herein.


(b)  That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.


(c)  To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering.


2.  The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 159d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.


3.  Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is again public policy as expressed in the Securities 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 or 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 Securities Act and will be governed by the final adjudication of such issue.


SIGNATURES


Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Toronto, Province of Ontario, Canada, on December 5, 2005

BONTAN CORPORATION INC.


2005 STOCK OPTION PLAN

1.  PURPOSE OF THE PLAN


The purpose of this stock option plan (the “Plan”) is to develop the interest of the directors, officers, employees and consultants who provide on-going services (other than services rendered in connection with the offer and sale of securities in a capital raising transaction) (collectively, “Optionees”) to Bontan Corporation Inc. (the “Corporation”) and its subsidiaries in the growth and development of the Corporation by providing such persons with the opportunity to acquire an increased proprietary interest in the Corporation and to better enable the Corporation and its subsidiaries to attract and retain persons of desired experience and ability.


2.  ADMINISTRATION


This Plan shall be administered by the board of directors of the Corporation (the “Directors”).


3.  GRANTING


The Directors may from time to time and in their discretion grant by way of resolution one or more stock options (“Stock Options”) to purchase voting common shares of the Corporation (“Common Shares”) to any one or more Optionees.


4.  NUMBER


The number of Common Shares reserved for issuance at any time pursuant to this Plan shall be 1,000,000 Common Shares in the capital of the Corporation.


Common Shares optioned under Stock Options that expire or otherwise terminate in accordance with the terms of the Plan shall be available to be optioned under subsequent grants of Stock Options.


5.  EXERCISE PRICES


The Directors shall fix the exercise price thereof (the “Exercise Price”), in their sole discretion at the time of grant of a Stock Option.


6.  VESTING


At the time of grant of a Stock Option, the Directors shall fix the date or dates on which the Optionee shall be entitled to exercise part or all of such Stock Option (the “Vesting Dates”).


7.  EXPIRTY DATE


At the time of grant of a Stock Option, the Directors shall fix the date on which such Stock Option shall expire (the “Expiry Date”), provided that such date shall be no later than five (5) years from the date of grant.


8.  STOCK OPTION AGREEEMENT


A written agreement shall be entered into between the Corporation and each Optionee to whom a Stock Option has been granted under this Plan, which such agreement shall set out the number of Common Shares under option, the Exercise Price, the Vesting Dates, the Expiry Date and such other terms as the Directors determine to be necessary or desirable, all of which shall be in accordance with the provisions of this Plan (the “Stock Option Agreement”).  The Stock Option Agreement will be in such form as the Directors may from time to time approve and may be executed and delivered for and on behalf of the Corporation by any one of the Chief Executive Officer or Chief Financial Officer of the Corporation or such other officer or director of the Corporation as the Directors may authorize.


9.  NO RIGHT OF ASSIGNMENT


All Stock Options granted pursuant to this Plan shall be personal to the Optionee and shall not be assignable or otherwise transferable except by will or the laws of descent and distribution.


10.  NO RIGHT AS SHAREHOLDER


An Optionee shall have no rights whatsoever as a shareholder in respect of any Common Shares under option to such Optionee unless and until he/she has exercised the related Stock Option in respect of such Common Shares.


11.  EXERCISE


A Stock Option may be exercised in whole or in part by the delivery to the Corporation at its head office of a written notice (the “Notice”) that specifies the number of Common Shares in respect of which such Stock Option is being exercised together with payment in an amount equal to the Exercise Price thereof multiplied by such number of Common Shares.


Upon the exercise of a Stock Option in whole or in part, the Corporation shall cause to be delivered to the Optionee a certificate registered in the name of such Optionee representing the number of Common Shares specified in the Notice.


Common Shares issued upon the valid exercise of a Stock Option shall be validly issued as fully paid and non-assessable.  The issuance of such Common Shares shall not require any further resolution or approval of the Directors and shall be deemed to have occurred on the date that the related Stock Option was exercised.


12.  VARIATIONS IN NUMBER


In the event that the Corporation:


(a)  declares a stock dividend or makes a distribution on the Common Shares in Common Shares;


(b)  subdivides or consolidates the issued and outstanding Common Shares into a greater or smaller number of Common Shares;


(c)  issues rights to all or substantially all of the holders of the Common Shares to purchase additional Common Shares at a price below the closing trading price of the Common Shares on the record date associated with such issuance; or


(d)  effects any transaction through which the Common Shares as a class are converted into or rendered exchangeable for any other securities,


then the Directors may make such substitution or adjustments in the aggregate number and class of shares reserved for issuance under the Plan and in the number, kind, and Exercise Price of shares subject to outstanding Stock Options and/or such other equitable substitution or adjustments as it may determine to be appropriate in its sole discretion; provided; however, that the number of shares subject to any Stock Option shall always be a whole number.


13.  VARIATIONS IN VESTING


In the event that an Optionee dies, such Optionee’s executor or executrix shall have the right to exercise part or all of all then outstanding and vested Stock Options on behalf of the Optionee’s estate until the earlier of the date set by the Directors at the time of the grant of such Stock Options (such date not to exceed one year after the date of death of the Optionee) or the Expiry Date.  All Stock Options not exercised by such date shall immediately and automatically terminate.  The Directors shall have the right, in their sole discretion, to provide at the time of the grant of the Stock Options of an Optionee, that all Stock Options granted to such Optionee shall be deemed to fully vest on the day prior to the Optionee’s death.  If the Directors do so, such Optionee’s executor or executrix shall have the right to exercise all of the outstanding Stock Options of such Optionee in a ccordance with the above.


In the event that an Optionee retires or resigns from his or her office and employment with the Corporation and all of its subsidiaries or is removed from such office and employment (whether with or without cause) or otherwise ceases to hold such office or employment for any reason (otherwise than as a result of the death of the Optionee or for cause), such Optionee shall have the right to exercise part or all of his or her then outstanding and vested Stock Options until the earlier of the date set out by the Directors at the time of the grant of such Stock Options in the Stock Option Agreement (such date not to exceed 90 days after the date such Optionee retires or is removed from such office) or the Expiry Date.  All such Stock Options not exercised by such date shall immediately and automatically terminate.  The Directors shall have the right, in their sole discretion, to provide at the time of the grant of the Stock Options of an Optionee, that all Stock Options granted to such Optionee shall be deemed to fully vest on the day prior to the resignation or removal of the Optionee from such office or employment.  If the Directors do so, such Optionee shall have the right to exercise all of the outstanding Stock Options of such Optionee in accordance with the above.  Notwithstanding the foregoing, in the event that an Option is removed from employment for cause, all then outstanding and unvested Stock Options granted to such Optionee shall immediately and automatically terminate.


In the event that:


(a)  the Directors determine that there is a reasonable probability that the Corporation will be reorganized, amalgamated or merged with, consolidated into or in any way combined with, another corporation;


(b)  the shareholders of the Corporation approve the liquidation, dissolution or winding-up of the Corporation or the sale, lease, exchange or other disposition of all or substantially all of the property of the Corporation;


(c)  a take-over bid, which is a “formal bid” (as that term is defined by the Securities Act (Ontario)), is made for any voting or equity securities of the Corporation; or


(d)  the Directors determine that there is a reasonable probability that the Corporation will experience a change of control (as determined by the Directors)


then the Directors may by resolution determine that all or any part of the outstanding and unvested Stock Options granted to any one or more Optionees shall vest on a date specified by such resolution and all such Stock Options shall be deemed to have vested on the date so specified.


14.  AMENDMENT OR DISCONTINUANCE OF PLAN


This Plan is subject to the rules of the stock exchange or exchange facility through which the Common Shares may at any time be traded (the “Rules”).  To the extent that any provision of this Plan conflicts with any Rule, such Rule shall govern and this Plan shall be deemed to be amended to be consistent therewith.


The Directors may amend or discontinue this Plan at any time (upon receipt of the approval of the Exchange), provided that no such amendment or discontinuance may, without the consent of any affected Optionee, alter or impair any Stock Options previously granted to such Optionee under this Plan.


15.  EFFECTIVE DATE


     This Plan is effective as of September 27, 2005.

          Re:          Issuance of Securities

Ladies and Gentlemen:

You have requested our opinion as your special U.S. securities counsel with respect to certain matters in connection with the filing by Bontan Corporation Inc. (the “Company”) of the Registration Statement on Form S-8 (the “Registration Statement”) with the Securities and Exchange Commission covering the sale of up to 3,100,000 shares of the Company’s common stock (the “Common Stock”) for possible issuance under the Company’s Robinson Stock Option Plan 2005 (collectively, the “Plans”.

In connection with this opinion, we have examined the Registration Statement and such other documents, records, certificates, memoranda and other instruments, as we deem necessary as a basis for this opinion.  We have assumed the genuineness and authenticity of all documents submitted to us as originals, the conformity to originals of all documents submitted to us as copies thereof and execution and delivery of all documents, where execution and delivery are a pre-requisite to the effectiveness thereof.

We advise you that we are licensed to practice in Minnesota.  Accordingly, our opinion assumes that the provincial laws of Ontario and the federal laws of Canada would yield the same opinion as application of the laws of the State of Minnesota and the federal laws of the United States.

On the basis of the foregoing, and in reliance thereon, we are of the opinion that the Common Stock, when issued in accordance with the Plans and the Registration Statement, will be validly issued, fully paid and non-assessable.

We consent to the filing of this opinion as an exhibit to the Registration Statement.

Very truly yours,

2.  The Option is 100% vested as of the date of this Agreement and you may exercise this Option from time to time for that number of Option Shares as you desire from the date of this Agreement until five years from the date of this Agreement at which point the Option shall expire (the “Expiration Date”).


3.  You may exercise this Option in whole or in part by the delivery to Bontan at its head office of a written notice (the “Notice”) specifying the number of Option Shares for which this Option is being exercised together with payment equal to such number of Option Shares times the Exercise Price.  Upon the timely exercise of this Option in whole or in part and receipt of the Exercise Price therefore, Bontan shall deliver to you a certificate registered in your name representing the number of Option Shares specified in the Notice which have been fully paid for.  Option Shares issued upon the valid exercise of this Option shall be validly issued as fully paid and non-assessable.  The issuance of such Option Shares shall not require any further resolution or approval of the Board of Directors of Bontan (the “Board”) and shall be deemed to have occurred on the date that this Option wa s exercised with respect to such Option Shares.


4.  In the event that Bontan:  (a) declares a stock dividend or makes a distribution on its common shares in common shares; (b) subdivides or consolidates the issued and outstanding common shares into a greater or smaller number of common shares; (c) effects any transaction through which its common shares as a class are converted into or rendered exchangeable for any other securities, then the Board may make such substitution or adjustments in the number and Exercise Price of common shares subject to this Option and/or such other equitable substitution or adjustments as the Board may determine to be appropriate in its sole discretion.


5.  In the event of your death, your executor or executrix shall have the right to exercise this Option with respect to any or all unexercised Option Shares on behalf of your estate until the earlier of the one year after the date of death or the Expiration Date.  The Option and Option Shares not exercised by such date shall immediately and automatically terminate.
