Annual Audited Consolidated Financial Statements



For the Annual Audited Consolidated Financial
Statements for the years ended December 31, 2015 and 2014, including the Independent Auditor’s Report with
respect thereto, of Cascades Inc. (the “Registrant” or “Cascades” or the “Corporation”), see
the excerpt of Cascades’ 2015 Annual Report attached hereto as Exhibit 13.2.



Management’s Discussion and Analysis



For management’s discussion and analysis
for the years ended December 31, 2015 and 2014, see the excerpt of Cascades’ 2015 Annual Report attached hereto as Exhibit
13.3.



Disclosure Controls and Procedures



Disclosure controls and procedures means controls
and other procedures that are designed to ensure that information required to be disclosed by the Registrant in the reports that
the Registrant files or submits under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded,
processed, summarized and reported within the time periods specified under Canadian securities laws and specified in the United
States Securities and Exchange Commission’s (the “SEC”) rules and forms and that such information required to
be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management,
including the President and Chief Executive Officer and the Vice-President and Chief Financial Officer, to allow timely decisions
regarding required disclosure.



Evaluation of Disclosure Controls and Procedures



The Registrant conducted an evaluation (under
the supervision and with the participation of the Registrant’s management, including the Chief Executive Officer and Chief
Financial Officer) as of December 31, 2015, pursuant to Rule 13a-15 promulgated under the Exchange Act and under National Instrument
52-109 adopted by the Canadian Securities regulatory authorities, of the effectiveness of the design and operation of the Registrant’s
disclosure controls and procedures. Based on this evaluation, the Registrant’s Chief Executive Officer and Chief Financial
Officer concluded that such disclosure controls and procedures were effective as of December 31, 2015.



It
should be noted that while the Registrant’s Chief Executive Officer and Chief Financial Officer believe that the Registrant’s
disclosure controls and procedures provide a reasonable level of assurance that they are effective, they do not expect
that the Registrant’s disclosure controls and procedures will prevent all errors and fraud. A control system, no matter how
well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are
met.



Management’s Report on Internal Control
over Financial Reporting



Management’s Report to the shareholders
of Cascades Inc. on internal control over financial reporting for the year ended December 31, 2015 is included in Exhibit 13.2
to this Annual Report on Form 40-F.



Management conducted an assessment of the effectiveness
of the Corporation’s internal control over financial reporting, as at December 31, 2015 based on the framework and criteria
established in Internal Control-Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission
(2013 COSO Framework). Based on this evaluation, management has concluded that the Corporation’s internal control over financial
reporting was effective as at December 31, 2015.



It
should be noted that while the Registrant’s Chief Executive Officer and Chief Financial Officer believe that the Registrant’s
internal control over financial reporting provide a reasonable level of assurance that they are effective, they do not expect
that the Registrant’s internal control over financial reporting will prevent all errors and fraud. A control system, no matter
how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system
are met.











Changes in Internal Controls over Financial
Reporting





In July 2015, the Registrant initiated the first phase of the
centralization of the accounting function within its Shared Services Centre and it ensured that appropriate internal control measures
had been established and maintained with respect to financial reporting. There was no change in the Registrant’s internal
controls over financial reporting that occurred during the period covered by this report that has materially affected, or is reasonably
likely to materially affect its internal controls over financial reporting.



Code of Ethics



The Corporation has adopted a Code of Ethics
that applies to all directors, officers and employees, including the Corporation’s principal executive officer, principal
financial officer, principal accounting officer or controller, or persons performing similar functions. For a discussion of the
Corporation’s Code of Ethics, see page 11 of Cascades’ Annual Information Form for the year ended December 31, 2015
(“AIF”) attached hereto as Exhibit 13.1. There were neither amendments to nor waivers, including implicit waivers,
from any provision of the Code of Ethics during the year ended December 31, 2015 that applied to the Corporation’s principal
executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions.
The Code of Ethics is available on the Corporation’s website at www.cascades.com.



Audit Committee



The Registrant has a separately designated
standing audit committee (the “Audit and Finance Committee”) as defined in Section 3(a)(58)(A) of the Exchange Act.
The Audit and Finance Committee is composed entirely of directors who are “independent”, as such term is defined in
the listing standards of the New York Stock Exchange. All members of the Audit and Finance Committee are financially literate and
there is one “audit committee financial expert”. In considering criteria for the determination of financial literacy,
the Board of Directors considers the ability to read and understand a set of financial statements that present a breadth and level
of complexity of accounting issues that are generally comparable to the breadth and complexity of the issues that can reasonably
be expected to be raised by the Registrant’s financial statements. In determining whether Audit and Finance Committee members
are “audit committee financial experts”, the Board of Directors and the Audit and Finance Committee have considered
the attributes set forth in Form 40-F. The “audit committee financial expert” is Laurence G. Sellyn. The other members
of the Audit and Finance Committee are Georges Kobrynsky and David McAusland.

Certain statements in this Annual Report on
Form 40-F or in documents incorporated by reference herein including statements regarding future results and performance, are forward-looking
statements (as such term is defined, under the United States Private Securities Litigation Reform Act of 1995) based on current
expectations. The accuracy of such statements is subject to a number of risks, uncertainties and assumptions that may cause actual

by insurance, labor disputes, work stoppages or increased labor costs, difficulty recouping its investments in joint ventures of
other companies that Cascades does not control, difficulties associated with acquiring companies, or integrating acquired companies,
as part of Cascades’ growth strategy, the impairment of Cascades’ goodwill or other intangible assets, changes in the
control of Cascades‘ equity capital, changes in strategy or management brought about by its existing shareholders or similar
changes relating to its control and management, Cascades’ inability to retain key personnel or attract and retain other talented
employees, and fluctuations in currency exchange rates. Reference is made to the section entitled “Risk Factors” on
