Exhibit 4.3

DESCRIPTION OF THE REGISTRANT'S SECURITIES

REGISTERED PURSUANT TO SECTION 12 OF THE

SECURITIES EXCHANGE ACT OF 1934

As of the date of the Annual Report on Form 10-K of which this Exhibit 4.3 is a part, IntelGenx Technologies Corp. (the "Company", "we", "us" or "our") has one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended: the Company's common stock (the "Common Stock").

Description of Common Stock

The following description of our Common Stock is a summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to our Certificate of Incorporation, as amended, and our Bylaws, as amended, each of which are incorporated by reference as an exhibit to the Annual Report on Form 10-K of which this Exhibit 4.3 is a part.

The Company has 110,259,653 shares of Common Stock outstanding.

The holders of Common Stock are entitled to one vote per share on all matters voted on by stockholders, including the election of directors. Except as otherwise required by law, the holders of Common Stock exclusively possess all voting power. The holders of Common Stock are entitled to dividends as may be declared from time to time by our board of directors from funds available for distribution to holders. No holder of Common Stock has any pre-emptive right to subscribe to any securities of ours of any kind or class or any cumulative voting rights.

Rights Upon Dissolution or Winding Up

The Delaware General Corporation Law provides that upon dissolution, liquidation or winding-up of the Company, holders of Common Stock have the lowest priority in the distribution of assets and will only receive a distribution if all senior obligations have been paid.  If all senior obligations have been paid, the holders of shares of Common Stock will be entitled to receive our assets available for distribution proportionate to their pro rata ownership of the outstanding shares of Common Stock.

Anti-Takeover Effects of Various Provisions of Delaware Law and Our Certificate of Incorporation and By-laws

The Delaware General Corporation Law, our certificate of incorporation and our by-laws contain provisions that may have some anti-takeover effects and may delay, defer or prevent a tender offer or takeover attempt that a stockholder might consider in his, her or its best interest, including those attempts that might result in a premium over the market price for the shares held by stockholders.

Delaware Anti-Takeover Statute

We are subject to Section 203 of the Delaware General Corporation Law ("Section 203"). Subject to specific exceptions, Section 203 prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the time the stockholder becomes an interested stockholder, unless:

• the business combination, or the transaction in which the stockholder became an interested stockholder, is approved by our board of directors prior to the time the interested stockholder attained that status;
• upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding those shares owned by persons who are directors and also officers and 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 after the time a stockholder became an interested stockholder, the business combination is approved by our board of directors and authorized at an annual or special meeting of stockholders by the affirmative vote of at least two-thirds of our outstanding voting stock that is not owned by the interested stockholder.

"Business combinations" include mergers, asset sales and other transactions resulting in a financial benefit to the interested stockholder. Subject to various exceptions, in general, an "interested stockholder" is a stockholder who, together with his, her or its affiliates and associates, owns, or within three years did own, 15% or more of the shares of our outstanding voting stock. These restrictions could prohibit or delay the accomplishment of mergers or other takeover or change of control attempts with respect to us and, therefore, may discourage attempts to acquire us.
