FULL DESCRIPTION OF MATERIAL CHANGE

5.1

Full Description of Material Change:

On December 15, 2016, Catalyst gave an update on the terms of its previously announced Recapitalization plan. The Recapitalization would result in an exchange of the Company's PIK Toggle Senior Secured Notes due 2017 (the "Notes") for:

(i)

a new secured term loan in the principal amount of US$135 million, plus accrued and unpaid interest on the Notes from November 1, 2016 to but excluding the effective date of the Recapitalization, which will mature five years from the effective date of the Recapitalization (the "New Secured Term Loan"); and

(ii)

Common Shares representing approximately 95% of the outstanding Common Shares after giving effect to the Recapitalization.

Moreover, in connection with the Recapitalization, the minority shareholders of Catalyst will have an opportunity to vote on the Privatization Transaction pursuant to which all existing Common Shares outstanding before the Recapitalization, other than the Common Shares held by the Supporting Parties, would be repurchased for cancellation by Catalyst for cash consideration equal to C$0.50 per Common Share. Total consideration payable by Catalyst in connection with the Privatization Transaction would be approximately C$2.2 million in the aggregate.

The Privatization Transaction is subject to approval by the minority shareholders of Catalyst pursuant to a vote separate from the vote with respect to the Recapitalization. Completion of the Recapitalization is not conditioned upon approval by the minority shareholders of the Privatization Transaction. In addition, the completion of the Privatization Transaction is further conditioned upon receipt of discretionary exemptive orders from the Canadian securities regulatory authorities to the effect that Catalyst would cease to be a reporting issuer following the completion of such Privatization Transaction.

Support for the Recapitalization and the Privatization Transaction includes the Recapitalization Support Agreement dated October 30, 2016, as amended, entered into by the Company and certain funds and entities managed or controlled by Oaktree Capital Management, L.P. ("Oaktree"), Mudrick Capital Management, L.P. ("Mudrick") and Cyrus Capital Partners, L.P. ("Cyrus") (collectively, the "Supporting Parties"), whereby the Supporting Parties undertook to vote Common Shares representing approximately 70% of the issued and outstanding Common Shares and Notes representing approximately 87% of the outstanding Notes, in each case in favor of the Recapitalization and the Privatization Transaction.

The Recapitalization Support Agreement was amended on December 14, 2016 to provide that the Supporting Parties shall also vote in favour of the Privatization Transaction in addition to voting in favour of the Recapitalization.

In addition, certain funds and entities managed or controlled by Stonehill Capital Management, LLC have entered into support agreements on December 14, 2016 pursuant to which they have agreed to vote Common Shares representing approximately 9.98% of the issued and outstanding Common Shares in favor of both the Recapitalization and the Privatization Transaction.

PricewaterhouseCoopers LLP ("PwC") has provided opinions (the "Fairness Opinions") to the Independent Committee and the Board to the effect that, as of October 31, 2016: (a) the Recapitalization is fair, from a financial point of view, to the Company, the minority shareholders of the Company and the Noteholders, and (b) the Privatization Transaction is fair, from a financial point of view, to the minority shareholders of the Company.

Additionally, PwC provided the Independent Committee and the Board with a formal valuation (the "Formal Valuation") pursuant to Multilateral Instrument 61-101 – Protection of Minority Securityholders in Special Transactions, which concluded that the fair market value of the Common Shares, as at October 31, 2016, was $NIL. The Formal Valuation also concluded that the fair market value of the Common Shares after the Recapitalization, as at the valuation date of October 31, 2016, is in the range of $2 million to $45 million, which implies a per Common Share value in the range of $0.01 to $0.15, with a mid-point of $0.08 per Common Share.

The PwC report containing the Fairness Opinions and the Formal Valuation was prepared for the sole use of the independent committee and the Board and is subject to the scope of review, assumptions and limitations set forth therein. The Formal Valuation and Fairness Opinion are one factor, among others, considered by the independent committee and the Board in making their recommendations to shareholders and the holders of Notes to vote in favour of the Recapitalization and the Privatization Transaction. The PwC report is appended to the Management Information Circular referred to below and should be read in its entirety.

Additionally, in connection with the Recapitalization, the Company has obtained commitments from its lenders under each of the its asset based loan facility ("ABL Credit Facility") and senior secured term loan (the "Existing Senior Secured Term Loan") in order to extend the maturity date of such facilities to July 31, 2020, conditional upon the completion of the Recapitalization on or before January 31, 2017.

Management of Catalyst and the Board believe that the Recapitalization would have the following benefits:

(a)

the Recapitalization would improve the Company's financial strength and liquidity and reduce its financing risk by:

extinguishing approximately US$125 million of debt;

relieving the Company from its obligation to pay the accrued and unpaid interest on the Notes for the period up to the November 1, 2016 interest payment date, in the amount of US$14.3 million;

allowing the Company to pay in kind all of the interest on the New Secured Term Loan during the first year following the effective date of the Recapitalization, with the Company's option to pay in kind up to 50% of interest for all subsequent years (or, with the consent of the lenders, all of the interest may be paid-in-kind during the second year after the effective date), thereby substantially reducing annual cash interest payments; and

positioning the Company to utilize the resulting enhancement in liquidity to make investments in the Company that could enable the Company to transition from its reliance on existing product offerings to product offerings that would provide improved valued-added opportunities;

(b)

provide Catalyst with the opportunity to pursue a viable alternative, failing which it would have been at greater risk of not repaying or refinancing certain of its debt obligations as they came due in July and October 2017, which would have a negative impact on Catalyst; and

(c)

Catalyst's trade vendors and other suppliers would not be adversely impacted.

Additionally, management of Catalyst and the Board believe that the Privatization Transaction would have the following benefits:

(a)

the Privatization Transaction would allow the Company to substantially reduce its reporting costs; and

(b)

given that Catalyst may not be able to satisfy the continued listing requirements of the Toronto Stock Exchange following the completion of the Recapitalization, the Privatization Transaction would provide liquidity to the minority shareholders that may not otherwise be available.

To the knowledge of Catalyst and assuming that a total of 276,023,849 Common Shares are issued under the Recapitalization (based on the number of Common Shares issued and outstanding and the principal amount of the Notes outstanding), after giving effect to the Recapitalization but before giving effect to the Privatization Transaction, there will be three shareholders who will beneficially own or exercise control or direction over, directly or indirectly, voting shares of Catalyst carrying more than 10% of the voting rights attached to all outstanding Common Shares, as follows:

(a)

Oaktree, which will hold approximately 97,171,160 Common Shares, representing approximately 33.4% of the outstanding Common Shares after the Recapitalization but before giving effect to the Privatization Transaction;

(b)

Cyrus, which will hold approximately 95,470,813 Common Shares, representing approximately 32.9% of the outstanding Common Shares after the Recapitalization but before giving effect to the Privatization Transaction; and

(c)

Mudrick, which will hold approximately 56,952,648 Common Shares, representing approximately 19.6% of the outstanding Common Shares after the Recapitalization but before giving effect to the Privatization Transaction.

Finally, the Company also reported that it was informed by the Supporting Parties that they terminated on December 14, 2016 the support agreement entered into with KGI in accordance with its terms. Pursuant to such support agreement, the Supporting Parties would have voted in favor of the proposal by KGI to acquire Catalyst.

Approvals by the shareholders and the holders of Notes will be sought at meetings to be held on January 17, 2017. Completion of the Recapitalization is subject to certain approvals, including those of the Toronto Stock Exchange and the Supreme Court of British Columbia, as well as certain other customary closing conditions. Assuming the receipt of all required approvals and the satisfaction of the closing conditions, it is anticipated that the Recapitalization will be completed and become effective by the end of January 2017.

The foregoing description of the Recapitalization and the Privatization Transaction does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Management Information Circular. A copy of the Management Information Circular was mailed to the holders of Common Shares and Notes of Catalyst, and was filed on Catalyst's SEDAR profile at www.sedar.com on December 16, 2016.
