Life Sciences Announces Re-Pricing of Short Form Offering Document

CALGARY, ALBERTA--(Marketwire - April 28, 2011) - Life Sciences Institute Inc. (TSX VENTURE:LSN) ("LSN" or the "Corporation") announces that it has received TSX Venture Exchange ("TSXV") consent to re-price its previously announced short form offering document ("SFOD"). The amended SFOD will, upon filing and subsequent approval from the TSXV, allow the Corporation to complete its previously announced financing (the "SFOD Offering") of up to $2,000,000 in units of the Corporation. The Units are being offered at a price of $0.05 per unit (each, a "Unit") and each Unit will be comprised of: (i) one common share in the capital of the Corporation (a "Common Share"); and (ii) one non-transferable Common Share purchase warrant (a "Warrant"). Each Warrant will entitle the holder thereof to purchase one Common Share for a period of twenty-four (24) months from the closing date at an exercise price of $0.10 per Common Share with an accelerated expiry date, subject to notice from the Corporation, of thirty (30) days from the date such notice is provided, if the Common Shares trade and if the closing price of the Common Shares on the TSXV for any fifteen (15) consecutive trading days is equal or above $0.15 per Common Share.

As previously announced, Wolverton Securities Ltd. ("Wolverton") will act as the lead agent on the SFOD Offering. Wolverton will receive a commission equal to 8.0% of the gross proceeds received by the Corporation from sales pursuant to the Offering. Wolverton will also receive an option to acquire up to that number of units ("Agent's Units") that is equal to 8.0% of the aggregate number of Units sold pursuant to the SFOD Offering, at price of $0.05 per Agent's Unit for a period of 36 months from the date of issue. Each Agent's Unit will consist of one Common Share and one Warrant. The Warrants issuable upon the exercise of the Agent's Units will expire twenty-four (24) months from the date of issuance of the option.

The Corporation has also received TSXV consent to re-price its previously announced flow-through financing (the "FT Offering, and together with the SFOD Offering, the "Offerings") at $0.06 per unit ("FT Unit"). Each FT Unit will be comprised of: (i) one flow-through Common Share; and (ii) one-half of one non-transferable common share purchase warrant (each whole warrant, a "FT Warrant"). Each FT Warrant will entitle the holder thereof to purchase one Common Share for a period of twenty-four (24) months from the closing date at an exercise price of $0.10 per Common Share with an accelerated expiry date, subject to notice from the Corporation, of thirty (30) days from the date such notice is provided, if the Common Shares trade and if the closing price of the Common Shares on the TSXV for any fifteen (15) consecutive trading days is equal or above $0.15 per Common Share. The Corporation must issue the accelerated expiry notice to holders of each of the SFOD Warrants and the FT Warrants concurrently.

The net proceeds to be received by the Corporation from both the SFOD Offering and the FT Offering will be used by the Corporation primarily for the purposes of completing drilling programs and acquiring seismic and for general working capital purposes.

The filing of the amended SFOD with the TSXV will occur within two business days after the issuance of this press release. As announced on January 26, 2011, the Offerings must raise aggregate gross proceeds of at least $2,850,000. Once the TSXV has issued an Exchange Bulletin indicating acceptance of the SFOD, the Offerings must be closed within 30 days thereof. The Corporation has an additional 3 business days to submit final documentation to the TSXV. There is no assurance that such final documentation will be submitted and TSXV approval granted within that time period.
