ProSep Provides Details on its Delay in Filing Annual Disclosure Documents

MONTREAL, QUEBEC--(Marketwired - April 12, 2013) - ProSep Inc. (TSX:PRP) ("ProSep" or the "Company"), dedicated to providing process solutions to the oil and gas industry, today wishes to provide more details on the previously disclosed delay of the Company in filing its annual audited financial statements (and related CEO and CFO certifications as required by National Instrument 52-109 Certification of Disclosure in Issuers' Annual and Interim Filings), the accompanying management's discussion and analysis as well as its annual information form for the year ended December 31, 2012 (collectively, the "2012 Annual Disclosure Documents") and on the steps taken by the Company in order to meet its disclosure obligations.

As previously disclosed on April 1, 2013, the Company was not able to file the 2012 Annual Disclosure Documents within the period prescribed for the filing of such documents under Parts 4, 5 and 6 of National Instrument 51-102 respecting Continuous Disclosure Obligations, namely within 90 days from its year end date.

Despite substantial efforts, the Company is still not in a position to file its 2012 Annual Disclosure Documents, primarily due to additional delays required to complete the closing of the sale of the Company's interest in ProSep Kolon Company Ltd. (the "Transaction") and the evaluation of the effects of new conditions proposed by one of the Company's subsidiary's lender pursuant to a breach of covenant under its credit facility (as disclosed in a press release dated March 19, 2013), together with additional delays required to clarify with its auditors the work assumptions in relation with their audit of the 2012 Annual Disclosure Documents.

ProSep's board of directors and its management are working expeditiously to meet the Company's obligations relating to the filing of the 2012 Annual Disclosure Documents and address the matters outlined above. More particularly, the Company is working towards completing the Transaction, evaluating the effects of the new conditions proposed by such lender and clarifying the work assumptions in relation with the audit of the 2012 Annual Disclosure Documents with its auditors. In light of these continuous efforts and steps to be taken, the Company expects to file the 2012 Annual Disclosure Documents on or about May 15, 2013.

The Autorité des Marchés Financiers (the "AMF") has issued today a management cease trade order (the "MCTO") which restricts all trading in securities of the Corporation, whether direct or indirect, by management and insiders of the Company. The MCTO is valid for a period of 15 days. The issuance of a MCTO does not affect the ability of persons who are not insiders of the Company to trade in the Company's securities.

In particular, forward-looking statements regarding ProSep's plans for its business development strategy, anticipated customer orders, sales and revenues, financial and operational projections and anticipated results, anticipated results of field testing with potential customers and expected benefits of ProSep's proprietary technologies; and anticipated impact on ProSep of the factors discussed under the heading "Selected Risks" in the latest management discussion and analysis document ("MD&A"). These forward-looking statements are based on, among other things, management's assumptions, expectations, estimates, objectives, plans and intentions as of the date hereof pertaining to, but not limited to demand for ProSep's solutions, projected revenues and expenses, the economic and industry environments in which the Company operates or which could affect its activities, the Company's ability to attract new customers, projected operating costs and cost of raw materials and energy supply, expected timing and amount of capital expenditures program of ProSep's potential customers, target market acceptance of ProSep's solutions, current and future solutions performance, evolving market conditions for oil & gas producers; and success of commercialization approach and strategic partnership initiatives. Although ProSep believes that the expectations and assumptions on which the forward-looking statements are based are reasonable, undue reliance should not be placed on the forward-looking statements because ProSep can give no assurance that they will prove to be correct.

ProSep cannot assure investors that any of these forward-looking statements will prove to be accurate. Further, if any of these statements are inaccurate, the inaccuracy may be material. Actual performance and results could differ materially from those currently anticipated in the forward-looking statements due to a number of factors and risks. Some of the factors that could cause such differences include, but are not limited to uncertainty as to market acceptance of new solutions and possible technological change, competition, economic environment and especially conditions in the oil & gas industry, legislative or regulatory developments, ProSep's ability to penetrate core markets, expand into new markets and manage future growth, the need for additional financing and uncertainties as to access to sufficient capital financing on acceptable terms, uncertainty as to achievement of profitability and ability to meet cash requirements, availability and retention of management and key personnel, the long sales and implementation cycles for ProSep's solutions, reliance on major customers, manufacturing, project execution, product defect and product liability risks, dependence on third party suppliers, exchange rate and currency fluctuations, protection of ProSep's intellectual property rights; and risks related to ProSep's foreign operations and compliance with anti-corruption and anti-bribery laws. Assumptions, expectations and estimates made in the preparation of forward-looking statements and risks that could cause actual results to differ materially from current expectations are further discussed under " Selected Risks" in the latest MD&A. In light of the significant risks and uncertainties in these forward-looking statements, investors should not place undue reliance on or regard these statements as a representation or warranty by the Company or any other person that the Company will achieve its objectives, strategies and plans in any specified time frame, if at all.
