Item 1.01.
Entry into a Material Definitive Agreement.
 
As previously disclosed, Gran Tierra Energy Inc. (“Gran Tierra”) sold an aggregate of 50,000,000 units of Gran Tierra’s securities at a price of $1.50 per unit in a private offering for gross proceeds of $75 million (the “Purchase Price”), pursuant to three separate Securities Purchase Agreements, dated June 20, 2006, and one Securities Purchase Agreement, dated June 30, 2006 (collectively, the “2006 Offering”). Each unit comprised one share of Gran Tierra’s common stock and one warrant to purchase one-half of a share of Gran Tierra’s common stock at an exercise price of $1.75 for a period of five years, resulting in the issuance of 50,000,000 shares of Gran Tierra’s common stock and warrants to purchase 25,000,000 shares of Gran Tierra’s common stock. In connection with the issuance of these securities, Gran Tierra entered into four separate Registration Rights Agreements with the investors pursuant to which Gran Tierra agreed to register for resale the shares (and shares issuable pursuant to the warrants) issued to the investors in the offering by November 17, 2006 (the “Mandatory Effective Date”). Since the registration statement was not declared effective by the Securities and Exchange Commission by that date, Gran Tierra accrued approximately USD $7.75 Million in liquidated damages.
 
On June 27, 2007, under the terms of the Registration Rights Agreements, Gran Tierra obtained a sufficient number of consents from the signatories to the agreements waiving Gran Tierra’s obligation to pay in cash the accrued liquidated damages. Gran Tierra agreed to amend the terms of the warrants issued in the 2006 Offering by reducing the exercise price of the warrants to $1.05 and extending the life of the warrants by one year.
 
Item 8.01.
Other Events.
 
On June 29, 2007, Gran Tierra issued a press release announcing the waiver. A copy of the press release is attached as Exhibit 99.1 to this current report and is incorporated herein by reference.
