HLT Energies Inc. Announces Private Placement

MONTREAL, QUEBEC (TSX VENTURE: HES) today announced the details of the proposed private placement of a $225,000 secured convertible debenture initially announced in its press release dated December 10, 2007.

The private placement will consist of a $225,000 secured convertible debenture (the "Debenture"), maturing five years from its date of issuance (the "Maturity Date") and bearing interest at an annual rate of 6%. The Debenture will be secured by a universal hypothec against the assets of HLT Energies. The Debenture will be held jointly by two arm's length private investors, in proportion to their contributions and will no longer constitute a "related party" transaction within the meaning of Regulation 61-101 respecting protection of minority security holders in special transactions.

The principal amount of the Debenture is convertible into units of HLT Energies (the "Units") as follows: (i) at a conversion price of $0.165 per Unit during the period commencing the 19th month from the date of issuance until the 24th month from the date of issuance, inclusively (the "First Term"); (ii) at a conversion price of $0.19 per Unit during the period commenting the 25th month from the date of issuance until the 36th month from the date of issuance, inclusively (the "Second Term"); (iii) at a conversion price of $0.20 per Unit during the period commencing the 37th month from the date of issuance until the 48th month from the date of issuance, inclusively (the "Third Term"); and (iv) at a conversion price of $0.22 per Unit during the period commencing the 49th month from the date of issuance until the 60th month from the date of issuance, inclusively (the "Fourth Term").

Each Unit will consist of one common share in the share capital of HLT Energies (the "Common Share") and one Common Share purchase warrant (the "Warrant"). Each Warrant will entitle the holder thereof to acquire a Common Share at an exercise price of $0.165, $0.19, $0.20 or $0.22 depending on whether the Warrant is exercised during the First Term, the Second Term, the Third Term or the Fourth Term, respectively at any time from the date of issuance of the Warrant up until the earlier of (i) two years from the date of conversion of the Debenture or (ii) the Maturity Date of the Debenture. The Warrants and the Common Shares will be subject to a 4-month hold period during the First Term.

Finally, in the event HLT Energies elects to repay the Debenture prior to the First Term, the holders of the Debenture will have the option to convert the principal amount of the Debenture into Units at a conversion price of $0.165 per Unit. The exercise price of the Warrants obtained upon conversion of the principal amount of the Debenture will be $0.165.

The anticipated closing date is on or around June 2, 2008. Closing is subject to the approval of the TSX Venture Exchange.
