NEWS RELEASE

ISOTECHNIKA REPORTS FIRST QUARTER

2013 FINANCIAL RESULTS

Edmonton, Alberta – May 15, 2013 (ISA:TSX): Isotechnika Pharma Inc. (the “Company”) has released its financial results for the first quarter ended March 31, 2013.

Recent Developments

On February 5, 2013 the Company announced that it had signed a binding term sheet (the “Term Sheet”) with privately held Aurinia Pharmaceuticals Inc. (“Aurinia”) for the merger of the two companies, creating a clinical development stage pharmaceutical company focused on the global nephrology market.

The Term Sheet sets forth the main criteria to be incorporated into a definitive merger agreement under which the Company will acquire 100% of the outstanding securities of Aurinia. The merger is expected to be effected by an exchange of Isotechnika shares for securities of Aurinia, resulting in a 65:35 post-merger ownership split between Isotechnika and Aurinia, respectively.

In addition, the Company and Aurinia have negotiated a tripartite settlement with ILJIN Life Science Co., Ltd. (“ILJIN”) pursuant to which, upon the successful completion of the proposed merger, the combined company will re-acquire full rights to voclosporin for autoimmune indications including lupus, and transplantation in the United States, Europe and other regions of the world, outside of Canada, Israel, South Africa, China, Taiwan and Hong Kong. In return, ILJIN will be entitled to receive certain pre-defined future milestone payments in the aggregate amount of $10 million, plus up to $1.6 million upon the combined company reaching certain financing milestones. ILJIN will also own approximately 25% of the issued and outstanding shares of the combined company.

The transaction is subject to certain closing conditions including, among others, the negotiation and completion of a merger agreement, acceptance and approval by the Toronto Stock Exchange and the approval of Isotechnika’s shareholders.

The consolidation of the intellectual property through the merger and reaching a settlement agreement with ILJIN provides the combined company with a much higher probability of being able to obtain the necessary funding to continue the development of voclosporin for the lupus indication. Further, the combined company will be able to continue to explore strategic global partnership transactions for the transplant indication. Ideally, the company would advance both transplantation and lupus nephritis to optimize shareholder value. A combined company, having both the lupus nephritis and renal transplantation indications under a single corporate umbrella, would likely offer the most commercially attractive opportunity.

Subsequent to March 31, 2013, the Company entered into two agreements with Canaccord Genuity Corp (the “Agent”), pursuant to which the Agent would assist the Company in selling, on a commercially reasonable efforts basis, securities of the Company in two private placements.

The first private placement will consist of up to 44.4 million units of the Company at a price of $0.045 per unit, or approximately $2 million in gross proceeds. Each unit in the first private placement (the “Unit Offering”) will consist of one common share of the Company (a “Share”) and one warrant (each, a “Warrant”), with each whole Warrant being exercisable for one Share at a price of $0.05 for a period of up to 36 months from the date of issuance. Given the number of securities to be issued pursuant to the Unit Offering, the Warrants issuable in the Unit Offering will not be exercisable until shareholder approval for their issuance has been obtained. The second private placement (the “Subscription Receipt Offering”)

will now consist of up to 22.2 million subscription receipts of the Company at a price of $0.045 per subscription receipt, or approximately $1 million in gross proceeds with each whole Warrant being exercisable for one Share at a price of $0.05 for a period of up to 36 months from the date of issuance. Each subscription receipt will entitle the holder thereof to one Share and one-half of a whole Warrant. The conditions for the conversion of the subscription receipts include receipt of shareholder approval and regulatory approval.

In order to help fund its operations in the immediate-term, the Company completed a private placement in April, 2013 with Dr. Richard Glickman, who is a major Aurinia shareholder and ILJIN consisting of the issuance of zero-coupon promissory notes in the aggregate principal amount of $400,000. The $400,000 is intended to be repaid in connection with the private placements. Dr. Glickman and ILJIN intend to subscribe for Units in the aggregate amount of $400,000.

Financial Results

For the first quarter ended March 31, 2013, the Company reported a consolidated net loss of $793,000 or $0.004 per common share, as compared to a consolidated net loss of $454,000 or $0.003 per common share for the same period in 2012.

Revenue decreased to $89,000 for the three months ended March 31, 2013, compared to $5.8 million for the three months ended March 31, 2012. The Company, in the first quarter of 2012, recorded license revenue of $4.4 million related to the Development, Distribution and License Agreement (“DDLA”) with ILJIN Life Science Co., Ltd. (“ILJIN”) which had previously been recorded as deferred revenue and also recorded $1.3 million of other revenue on the completion of a sale agreement with its partner, Lux Biosciences, Inc. for previously manufactured Active Pharmaceutical Ingredient.

Net research and development expenses decreased to $338,000 for the three months ended March 31, 2013, compared to $802,000 for the three months ended March 31, 2012. The Company had to reduce research and development costs, including wages and benefits to the extent possible due to its financial condition as the Company focused its efforts on financing activities and arranging the merger with Aurinia.

Corporate, administration and marketing expenses decreased to $498,000 for the first quarter of 2013, compared to $986,000 for the same period in 2012. Corporate and administration expenses decreased primarily due to lower professional and consulting fees, wages and benefits and travel expenses for the three months ended March 31, 2013 compared to the same period in 2012.

Other expense (income) reflected income (net) of $38,000 for the first quarter ended March 31, 2013 compared to expense of $4.2 million for the first quarter ended March 31, 2012. Other expense for the three months ended March 31, 2012 included a non-cash loss of $4.2 million on the ILJIN derivative financial instrument. There was no similar item for the three months ended March 31, 2013.
