EXPLANATORY NOTE

DragonWave Inc. ("we", "us", "our", the "Company" or the "Registrant") is a Canadian issuer eligible to file its annual report pursuant to Section 13 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, on Form 40-F pursuant to the multi-jurisdictional disclosure system of the Exchange Act. We are a "foreign private issuer" as defined in Rule 3b-4 under the Exchange Act. Our equity securities are accordingly exempt from Sections 14(a), 14(b), 14(c), 14(f) and 16 of the Exchange Act pursuant to Rule 3a12-3.

INCORPORATION BY REFERENCE

This Annual Report on Form 40-F shall be incorporated by reference into the Registrant's Form S-8, SEC File No. 333-167806, filed on June 25, 2010.

FORWARD-LOOKING STATEMENTS

This annual report on Form 40-F and the documents incorporated herein by reference, contain forward-looking statements and forward-looking information within the meaning of applicable securities laws. Such forward-looking statements or forward-looking information include, but are not limited to statements with respect to strategic plans and corporate goals and objectives.

Forward-looking statements, which involve assumptions and describe the future plans, strategies and expectations of the Company, are generally identifiable by use of the words "may", "will", "should", "continue", "expect", "anticipate", "estimate", "believe", "intend", "plan" or "project" or the negative of these words or other variations on these words or comparable terminology. Forward-looking statements include, without limitation, statements regarding strategic plans, and corporate goals and objectives. There can be no assurance that forward-looking statements will prove to be accurate and actual results such as the goals and objectives of the Company's compensation programs for executives and directors, performance, achievements or developments and future events could differ materially from those expressed or implied in such statements. The following are some of the important risk factors relating to DragonWave and its business that could cause actual results, performance, achievements or developments to differ materially from those discussed in the forward-looking statements:

• ability to successfully complete and integrate acquisitions of products or businesses, including the proposed acquisition of Nokia Siemens Networks, into our existing product lines and businesses and other risks associated with acquisitions;

• dependence on the development and growth of the market for high-capacity wireless communications services;

• reliance on a small number of customers for a large percentage of revenue;

• intense competition from several competitors;

• competition from indirect competitors;

• dependence on the ability to develop new products and enhance existing products;

• ability to successfully manage growth;

• a history of losses;

• dependence on establishing and maintaining relationships with channel partners;

• quarterly revenue and operating results which are difficult to predict and can fluctuate substantially;

• impact that the recent general economic downturn may still be having on customers;

• disruption resulting from economic and geopolitical uncertainty;

• currency fluctuations;

• exposure to credit risk for accounts receivable;

• pressure on DragonWave's pricing models;

• the allocation of radio spectrum and regulatory approvals for DragonWave's products;

• the ability of DragonWave's customers to secure a license for applicable radio spectrum;

• changes in government regulation or industry standards that may limit the potential market for DragonWave's products;

• risks associated with the possible loss of DragonWave's foreign private issuer status;

• risks and expenses associated with DragonWave's status as a public company;

• reliance on outsourced manufacturing;

• reliance on suppliers of components;

• ability to protect its own intellectual property and potential harm to DragonWave's business if it infringes the intellectual property rights of others;

• risks associated with software licensed by DragonWave;

• a lengthy and variable sales cycle;

Page 5: Dragonwave AR

• dependence on DragonWave's ability to recruit and retain management and other qualified personnel;

• exposure to risks resulting from its international sales and operations, including the requirement to comply with export control and economic sanctions laws; and

• product defects, product liability claims, or health and safety risks relating to wireless products.

The risks and uncertainties related to the risk factors listed above, and the materializing of such risk and uncertainties, may be materially increased by the completion of the anticipated acquisition by us of the microwave transport business of Nokia Siemens Networks. In particular, material risks and uncertainties following and contingent upon closing of the acquisition will include, without limitation:

• reliance on Nokia Siemens Networks for a large percentage of our revenues;

• increased cash requirements to fund acquired operations, and associated requirements to comply with debt financing covenants with our lenders, which should be understood in light of our history of losses noted above;

• increased exposure to global currency fluctuations;

• increased regulatory compliance obligations, including financial reporting obligations associated with completing a significant acquisition; and

• risks associated with acquisitions generally as detailed on in our most recently filed Annual Information Form, or AIF.

Although we have attempted to identify factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements and forward-looking information, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. Forward-looking statements and forward-looking information are based upon management's beliefs, estimates and opinions at the time they are made and we undertake no obligation to update forward-looking statements and forward-looking information if these beliefs, estimates and opinions or circumstances should change, except as required by applicable law. There can be no assurance that forward-looking statements and forward-looking information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements and information. Accordingly, readers should not place undue reliance on forward-looking statements and forward-looking information.

The list above is not exhaustive of the factors that may affect our forward-looking statements and forward-looking information. Some of the important risks and uncertainties that could affect forward-looking statements and forward-looking information are described further in the exhibits attached to this annual report on Form 40-F. In light of these risks, uncertainties and assumptions, the forward looking events discussed in this annual report on Form 40-F and the documents incorporated herein by reference, including, without limitation, our published financial guidance, may not occur.

Unless specifically stated otherwise, all dollar amounts in this annual report on Form 40-F are in U.S. dollars.

CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

At the end of the period covered by this annual report for the fiscal year ended February 29, 2012, an evaluation was carried out under the supervision of, and with the participation of, our management, including our Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO, which are our principal executive officer and principal financial officer, respectively, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act). Based upon that evaluation, our CEO and CFO have concluded that our disclosure controls and procedures were effective as at February 29, 2012, to give reasonable assurance that the information we are required to disclose in reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and (ii) accumulated and communicated to management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Management's Report on Internal Control over Financial Reporting

Our management is also responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f) as well as National Instrument 52-109 of the Canadian Securities Administration. These controls are designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control — Integrated Framework, our management concluded that our internal control over financial reporting was effective as of February 29, 2012.

Attestation Report of Independent Registered Public Accounting Firm

The attestation report of Ernst & Young LLP ("EY") is included in EY's report, dated May 2, 2012, to the shareholders of the Company, which accompanies the Registrant's audited consolidated financial statements for the fiscal year ended February 29, 2012, which is attached as Exhibit 99.1 to this annual report on Form 40-F and incorporated by reference herein.

Changes in Internal Control over Financial Reporting

During the period covered by this Annual Report on Form 40-F, no changes occurred in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

AUDIT COMMITTEE

Audit Committee

We have a separately designated standing Audit Committee established in accordance with section 3(a)(58)(A) of the Exchange Act and NASDAQ Rule 5605(c)(2). Our Audit Committee is composed of Tom Manley (Chair), Claude Haw, and Jean-Paul Cossart, each of whom, in the opinion of the directors, is financially literate and independent as determined under National Instrument 52-110 (Audit Committees) ("NI 52-110"), Rule 10A-3 of the Exchange Act and NASDAQ Rule 5605(a)(2). Information regarding the members of our Audit Committee can be found under "Audit Committee" in our most recently filed AIF.

The Audit Committee assists the board of directors in fulfilling its responsibilities for oversight of financial and accounting matters. In addition to recommending the auditors to be nominated and reviewing the compensation of the auditors, the Audit Committee is responsible for overseeing the work of the auditors and pre-approving non-audit services. The Audit Committee also reviews our annual and interim financial statements and news releases containing information taken from our financial statements prior to their release. The Audit Committee is responsible for reviewing the acceptability and quality of our financial reporting and accounting standards and principles and any proposed material changes to them or their application.

The Audit Committee has a published charter, which is available at www.sedar.com and on our website, www.dragonwaveinc.com .

Audit Committee Financial Expert

Our Board of Directors has determined that Thomas Manley qualifies as an "audit committee financial expert" within the meaning of the SEC's rules and each of the members of the audit committee is independent as determined under Exchange Act Rule 10A-3 and NASDAQ Rule 5605(a)(2). Information regarding each audit committee member's qualifications and experience can be found under "Audit Committee" in our most recently filed AIF.

The following table sets out the fees billed to us by Ernst & Young LLP and its affiliates for professional services for the year ended February 29, 2012 and the year ended February 28, 2011. During these years, E&Y was our only external auditor.

PRE-APPROVAL OF AUDIT AND NON-AUDIT SERVICES PROVID ED BY INDEPENDENT AUDITORS

In addition to recommending the auditors to be nominated and reviewing the compensation of the auditors, the Audit Committee is responsible for overseeing the work of the auditors and pre-approving non-audit services. As a matter of practice, the Audit Committee, and/or the Audit Committee Chairman acting on behalf of the Audit Committee, will generally pre-approve all audit and permitted non-audit services to be performed by our external auditors. None of the fees reported above under the heading "External Auditor Service Fees" that were paid to Ernst & Young LLP were approved by our Audit Committee pursuant to the de minimus exception provided by Section (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

OFF-BALANCE SHEET ARRANGEMENTS

CONTRACTUAL OBLIGATIONS

The following table presents a breakdown of our known outstanding contractual obligations by maturity as of February 29, 2012:

The amounts in the table above do not reflect the future tax consequences attributable to such amounts because we are unable to reasonably estimate the amount of such tax consequences.

NOTICES PURSUANT TO REGULATION BTR

We did not send any notices to directors and executive officers during the period covered by this annual report as required by Rule 104 of Regulation BTR concerning any equity securities in a pension or retirement plan subject to a blackout period and, generally, these requirements are inapplicable to us.

NASDAQ CORPORATE GOVERNANCE

Our common shares are quoted for trading on the NASDAQ Global Select Market under the symbol DRWI. NASDAQ Marketplace Rule 5615(a)(3) permits a foreign private issuer to follow its home country practice in lieu of certain of the requirements of the Rule 5600 Series. A foreign private issuer that follows a home country practice in lieu of one or more provisions of the Rule 5600 Series is required to disclose in its annual report filed with the SEC, or on its website, each requirement of the Rule 5600 Series that it does not follow and describe the home country practice followed by the issuer in lieu of such NASDAQ corporate governance requirements.

We do not follow Marketplace Rule 5620(c), but instead follow our home country practice. The NASDAQ minimum quorum requirement under Rule 5620(c) for a meeting of shareholders is 33.33% of the outstanding common shares. In addition, Rule 5620(c) requires that an issuer listed on NASDAQ state its quorum requirement in its governing documents. Our quorum requirement is set forth in our by-laws. A quorum for a meeting of our shareholders is two persons present in person or by proxy who, in the aggregate, hold at least 25% of the issued shares entitled to be voted at the meeting. The foregoing is consistent with the laws, customs and practices in Canada and the rules of the Toronto Stock Exchange.

INTERACTIVE DATA FILE

Concurrent with this filing, we have submitted to the SEC and posted on our corporate website, an Interactive Data File.

UNDERTAKING

We undertake to make available, in person or by telephone, representatives to respond to inquiries made by the SEC's staff, and to furnish promptly, when requested to do so by the SEC staff, information relating to: the securities registered pursuant to Form 40-F; the securities in relation to which the obligation to file an annual report on Form 40-F arises; or transactions in said securities.

CONSENT TO SERVICE OF PROCESS

We previously filed an Appointment of Agent for Service of Process and Undertaking on Form F-X with the SEC on May 6, 2010, with respect to the class of securities in relation to which the obligation to file this annual report on Form 40-F arises.

INDEPENDENT AUDITORS' REPORT OF REGISTERED PUBLIC A CCOUNTING FIRM

To the Shareholders of DragonWave Inc.

We have audited the accompanying consolidated financial statements of DragonWave Inc. , which comprise the consolidated balance sheets as at February 29, 2012 and February 28, 2011, and the consolidated statements of operations and comprehensive income (loss), changes in shareholders' equity and cash flows for each of the years in the two-year period ended February 29, 2012, and a summary of significant accounting policies and other explanatory information.

Management's responsibility for the consolidated financial statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with United States generally accepted accounting principles, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditors' responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditors' judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, the auditors consider internal control relevant to the entity's preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of DragonWave Inc. as at February 29, 2012 and February 28, 2011, and the results of its operations and its cash flows for each of the years in the two-year period ended February 29, 2012 in accordance with United States generally accepted accounting principles.

Other matter

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), DragonWave's internal control over financial reporting as of February 29, 2012, based on the criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated May 2, 2012 expressed an unqualified opinion on DragonWave Inc.'s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of: DragonWave Inc.

We have audited DragonWave Inc.'s internal control over financial reporting as of February 29, 2012, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). DragonWave Inc.'s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying reports from management. Our responsibility is to express an opinion on the company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, DragonWave Inc. maintained, in all material respects, effective internal control over financial reporting as of February 29, 2012 based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of DragonWave Inc. as of February 29, 2012 and February 28, 2011 and the related consolidated statements of operations and comprehensive income (loss), changes in shareholders' equity and cash flows for each of the two years in the period ended February 29, 2012 of DragonWave Inc. and our report dated May 2, 2012 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

[Expressed in US $000's except share and per share amounts]

1. NATURE OF BUSINESS AND BASIS OF PRESENTATION

DragonWave Inc. [the "Company"], incorporated under the Canada Business Corporations Act in February 2000, is in the business of developing next-generation broadband wireless backhaul and pseudowire equipment.

The Company's common shares are traded on the Toronto Stock Exchange under the trading symbol DWI and on NASDAQ Global Market under the symbol DRWI.

These consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, DragonWave Corp., incorporated in the state of Delaware, USA, DragonWave PTE Limited, incorporated in Singapore, 4472314 Canada Inc., incorporated in Canada, Axerra Networks Inc., incorporated in the state of Delaware, USA, DragonWave Networks Ltd., incorporated in Israel, DragonWave S.r.l, incorporated in Italy, DragonWave S.A.R.L., incorporated in Luxembourg, DragonWave LTDA, incorporated in Brazil, Axerra GMBH, incorporated in Germany, Axerra Networks Asia Pacific Limited, incorporated in Hong Kong, and its majority owned subsidiary, DragonWave HFCL India Private Limited. All intercompany accounts and transactions have been eliminated upon consolidation.

The consolidated financial statements of the Company have been prepared in United States dollars following United States Generally Accepted Accounting Principles ["U.S. GAAP"], as further discussed in note 2.

In the opinion of management, the consolidated financial statements reflect all adjustments, which consist only of normal and recurring adjustments, necessary to present fairly the financial position as at February 29, 2012 and February 28, 2011 and the results of operations, cash flows and changes in equity for the years ended February 29, 2012 and February 28, 2011.

2. SIGNIFICANT ACCOUNTING POLICIES

Adoption of United States Generally Accepted Accounting Principles

In February 2008, the Canadian Accounting Standards Board confirmed the transition from Canadian GAAP to International Financial Reporting Standards ["IFRS"] for all publicly accountable entities no later than fiscal years commencing on or after January 1, 2011. As a result, management undertook a detailed review of the implications of the Company having to report under IFRS and also examined the alternative available to the Company, as a Foreign Private Issuer in the United States, of filing its primary financial statements in Canada using U.S. GAAP, as permitted by the Canadian Securities Administrators' National Instrument 51-102, "Continuous Disclosure Obligations".

As a result of this analysis, management determined that the Company would adopt U.S. GAAP as its primary basis of financial reporting commencing March 1, 2011 on a retrospective basis. All comparative financial information contained in the consolidated financial statements has been revised to reflect the Company's results as if they had been historically reported in accordance with U.S. GAAP.

The adoption of U.S. GAAP did not have a material change on the Company's accounting policies or financial results. An adjustment in the amount of $154 was made to increase deficit as calculated by Canadian GAAP as at February 28, 2011 due to the adoption of U.S. GAAP.

Under Canadian GAAP, Investment Tax Credits (ITC's) were recognized as a reduction to the Company's Research and development expense. Under US GAAP, ITC's are recognized as a reduction to Income tax expense. During fiscal 2011, under Canadian GAAP, the Company recognized $380 as a reduction to research and development expense. Under US GAAP, the prior year results were impacted as follows: the Company's Income before taxes was adjusted $2,428 and the Company's tax expense was $421 as opposed to $2,808 and

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

$801 respectively as was stated under Canadian GAAP. The GAAP difference had no impact on the Company's consolidated Net and Comprehensive Income in the prior fiscal year.

Use of accounting estimates

The preparation of the consolidated financial statements in conformity with GAAP requires the Company's management to make estimates that affect the reported amounts of assets and liabilities and disclosure of contingent amounts of assets and liabilities as at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods presented. Actual results could differ from the estimates made by management.

The following include estimates by management: allowance for doubtful accounts, inventory allocations, inventory provisions, accrued liabilities, warranty provisions, contingent royalty, tax valuation allowance, impairment of intangible assets and goodwill, vendor specific objective evidence, estimated selling price and estimated returns as it relates to revenue recognition, and stock-based compensation.

These estimates and assumptions are based on management's historical experience, best knowledge of current events and conditions and actions that the Company may undertake in the future. Certain of these estimates require subjective or complex judgments by management about matters that are uncertain and changes in those estimates could materially impact the amounts reported in the consolidated financial statements and accompanying notes.

Foreign currency translation

The Company's operations and balances denominated in foreign currencies, including those of its foreign subsidiaries which are considered financially and operationally integrated, are translated into US dollars (USD) using the temporal method of translation: monetary assets and liabilities are translated at the period end exchange rate, non-monetary assets are translated at the historical exchange rate, and revenue and expense items are translated at the average exchange rate. Gains or losses resulting from the translation adjustments are included in income (loss).

The cumulative foreign currency translation adjustment included under accumulated other comprehensive loss within shareholders' equity on the consolidated balance sheets relates to the Company's adoption of USD as the functional and reporting currency which was effective March 1, 2010 and unrealized foreign currency translation gains or losses of our self-sustaining foreign subsidiary which are translated into USD using the current rate method. Under the current rate method, assets and liabilities are translated at the rate of exchange prevailing at the balance sheet date. Revenue and expenses are translated at the average exchange rate prevailing during the period.

Revenue recognition

The Company derives revenue from the sale of broadband wireless backhaul equipment which includes embedded software and a license to use said software and extended product warranties. Software is considered to be incidental to the product. Services range from installation and training to basic consulting. Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred and there are no significant remaining vendor obligations, collection of receivables is reasonably assured and the fee is fixed and determinable. Where final acceptance of the product is specified by the customer, revenue is deferred until acceptance criteria have been met.

[Expressed in US $000's except share and per share amounts]

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

The Company's business agreements may also contain multiple elements. Accordingly, the Company is required to determine the appropriate accounting, including whether the deliverables specified in a multiple element arrangement should be treated as separate units of accounting for revenue recognition purposes, the fair value of these separate units of accounting and when to recognize revenue for each element. For arrangements involving multiple elements, the Company allocates revenues to each element based on a selling price hierarchy. The selling price for a deliverable is based on its vendor specific objective evidence ("VSOE") if available, third party evidence ("TPE") if VSOE is not available, or estimated selling price ("ESP") if neither VSOE nor TPE is available. In multiple element arrangements, revenues are allocated to each separate unit of accounting for each of the deliverables using the relative estimated selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy. The Company has determined the selling price for the undelivered items using VSOE and the delivered items using ESP.

The Company generates revenue through direct sales and sales to distributors. The Company defers the recognition of a portion of sales to distributors based estimated sale returns and stock rotation granted to customers on products in the same period the related revenues are recorded. These estimates are based on historical sales returns; stock rotations and other known factors. During the current fiscal year the Company determined that there was sufficient history to base its estimates on and adapted our policy accordingly.

Revenue associated with extended warranty and advanced replacement warranty is recognized rateably over the life of the contracted service.

Revenue from engineering services or development agreements is recognized according to the specific terms and acceptance criteria as services are rendered.

The Company accrues estimated potential product liability as warranty costs when revenue on the sale of equipment is recognized. Warranty costs are calculated on a percentage of revenue per month based on current actual warranty costs and return experience.

Shipping and handling costs borne by the Company are recorded in cost of sales. Shipping and handling costs charged to customers are recorded as revenue, if billed at the time of shipment. Costs charged to customers after delivery are recorded in cost of sales.

The Company generates revenue through royalty agreements as a result of the use of its Intellectual Property. Royalty revenue is recognized as it is earned.

Cash and cash equivalents

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.

Short term investments

The Company has classified its short term investments as held for trading, which are carried at fair value with both realized and unrealized gains and losses included in net income (loss).

Financial instruments

The Company classifies its financial instruments as held-for-trading, held-to-maturity, available-for-sale, loans and receivables and other financial liabilities. The classification depends on the purpose for which the financial instruments were acquired, their characteristics and management's intent. Management determines the classification of financial assets and liabilities at initial recognition and the classification is not changed

subsequent to initial recognition. The Company designated its cash and cash equivalents and short term investments as held-for-trading which are measured at fair value, with changes in fair value being recorded in net earnings. Trade receivables and other receivables have been classified as loans and receivables which are measured at amortized cost. Accounts payable and accrued liabilities have been classified as other financial liabilities, which are measured at amortized cost.

Transaction costs directly attributable to the acquisition of financial assets are recorded in net income (loss)in the period in which they are incurred.

Inventory

Inventory is valued at the lower of cost and net realizable value ["NRV."] The cost of inventory is calculated on a standard cost basis, which approximates average actual cost. NRV is determined as the market value for finished goods, replacement cost for raw materials, and finished goods market value less cost to complete for work in progress inventory. Indirect manufacturing costs and direct labour expenses are allocated systematically to the total production inventory.

Income taxes

Income taxes are accounted for using the liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities are determined based on differences between the tax and accounting bases of assets and liabilities as well as for the benefit of losses available to be carried forward to future years for tax purposes that are more likely than not to be realized. Deferred income tax assets and liabilities are measured using enacted tax rates that apply to taxable income in the years in which temporary differences are expected to be recovered or settled. The Company provides a valuation allowance against its deferred tax assets when it believes that it is more likely than not that the assets will not be realized.

The Company determines whether it is more likely than not that an uncertain tax position will be sustained upon examination by the tax authorities. The tax benefit of any uncertain tax position that meets the more-likely-than-not recognition threshold is calculated as the largest amount that is more than 50% likely of being realized upon successful resolution. To the extent a full benefit is not expected to be realized, an income tax liability is effectively established. The Company recognizes accrued interest and penalties on unrecognized tax benefits as interest expense.

Management periodically reviews the Company's provision for income taxes and valuation allowance to determine whether the overall tax estimates are reasonable. When management performs its quarterly assessments of the provision and valuation allowance, it may be determined that an adjustment is required. This adjustment may have a material impact on the Company's financial position and results of operations.

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

Property and equipment

Property and equipment are stated at cost. Amortization is calculated using the straight-line method over the anticipated useful lives of the assets as follows:

Management evaluates the carrying value of its property and equipment assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. To the extent the estimated undiscounted future net cash inflows attributable to the asset are less than the carrying amount, an impairment loss is recognized. The amount of impairment loss to be recorded is the difference between the asset's carrying value and the net discounted estimated future cash flows.

Goodwill and intangible assets

Intangible assets include computer software, infrastructure systems software, customer relationships and developed technology, and are amortized over their estimated useful lives of 2 years, 3 years, 8 years, and 6 years respectively. Management evaluates the carrying value of its intangible assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. To the extent the estimated undiscounted future net cash inflows attributable to the asset are less than the carrying amount, an impairment loss is recognized. The amount of impairment loss to be recorded is the difference between the asset's carrying value and the net discounted estimated future cash flows.

Goodwill represents the excess of the purchase price over the estimated fair value of net tangible and intangible assets acquired in business combinations. The Company reviews the carrying value of goodwill on an annual basis or more frequently if circumstances indicate that it is more likely than not that the fair value of the goodwill is below its carrying amount. The goodwill impairment test is a three-step process which requires management to make judgmental assumptions regarding fair value. The first step in the impairment test is to assess qualitative factors to determine whether it is necessary to perform the subsequent two steps of the goodwill impairment test. The second step consists of estimating the fair value of our aggregated reporting unit. When the fair value of our reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not to be impaired and the third step of the impairment test is unnecessary. If the fair value is less than the carrying amount, the Company compares the implied fair value of the goodwill, determined as if a purchase had just occurred, to the carrying amount to determine the amount of impairment charge to be recorded. Changes in the estimates and assumptions used in assessing the projected cash flows could materially affect the results of management's evaluation.

Contingent royalty

In the event of an acquisition, the Company identifies any contingent royalties and recognizes the fair value of those liabilities based on the discounted expected cash outflows. Subsequent to the initial recognition and until the liabilities are settled, cancelled or expire, the Company accretes the liabilities using the initial discount

rate and subsequently amortizes the liability into cost of sales based on the forecasted sales over the liability's expected life.

Stock option plan and employee share purchase plan

The Company has a stock option plan and an employee share purchase plan which is described in note 12. The Company accounts for stock options granted to employees using the fair value method. In accordance with the fair value method, the Company recognizes estimated compensation expense related to stock options over the vesting period of the options granted, with the related credit being charged to contributed surplus.

The Company launched an employee share purchase plan on October 20, 2008. The plan includes provisions to allow employees to purchase Common shares. The Company will match the employees' contribution at a rate of 25%. Proceeds from employees and the cost of the matching shares are recorded in share capital and contributed surplus at the time the shares are issued. The shares contributed by the Company will vest 12 months after issuance with a corresponding compensation expense recognized in income (loss).

Expenses

The Company defined general and administration expenses to be administrative, finance, and operational costs. Sales and marketing expenses are defined as costs related to worldwide sales, marketing and product management. Research and development costs are defined as costs related to research and development related activities.

Research and development

Research costs are expensed as incurred. Development costs are expensed as incurred unless they meet generally accepted accounting criteria for deferral and amortization. Development costs incurred prior to establishment of technological feasibility do not meet these criteria, and are expensed as incurred.

Income per share

Basic income per share is calculated by dividing net income available to Common shareholders by the weighted average number of Common shares outstanding during the period. For all periods presented, the net income available to Common shareholders equates to the net income (loss).

In the computation of diluted earnings per share, the Company includes the number of additional common shares that would have been outstanding if the dilutive potential equity instruments had been issued.

Non-controlling interest

Non-controlling interest consists of the minority owned portion of the Company's 50.1% owned subsidiary, DragonWave HFCL India Private Limited.

ACCOUNTING POLICIES ADOPTED IN THE CURRENT FISCAL Y EAR

Non-Controlling Interest

The Company adopted ASC 810-10-65, Non-controlling Interests in Consolidated Financial Statements, which governs the accounting for and reporting of (1) non-controlling interest in partially owned consolidated subsidiaries and (2) the loss of control of subsidiaries. Significant changes to the accounting for non-controlling interests include (a) the inclusion of non-controlling interests in the equity section of the controlling entity's

consolidated balance sheets rather than in the mezzanine section and (b) the requirement that changes in the controlling entity's interest in the non-controlling interest, without a change in control, be recognized in the controlling entity's equity rather than being accounted for by the purchase method, which accounting under the purchase method would have given rise to goodwill.

Additionally, the adoption of ASC 810-10-65 requires that net income, as previously reported prior to the adoption of ASC 810-10-65, be adjusted to include the net income attributable to the non-controlling interest, and that a new separate caption for net income attributable to common shareholders of the Company be presented in the consolidated statements of operations. ASC 810-10-65 also requires similar disclosure regarding comprehensive income (loss). The Company has disclosed the consolidated balance sheets and consolidated statements of operations and comprehensive income (loss) in accordance with this ASC.

Multiple-deliverable revenue arrangements

In November 2009, the FASB issued ASU 2009-13, which amends the guidance in ASC 605-25 on multiple element revenue arrangements. The amendment eliminates the residual method of allocation and requires that any arrangement consideration be allocated to all deliverables using the relative selling price method with any discounts allocated proportionally to each deliverable. The amendment also establishes a selling price hierarchy for determining the selling price of each deliverable. The selling price, formally referred to as fair value, will be based on vendor-specific objective evidence if available, third-party evidence if vendor specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. For the Company, this ASU is effective for revenue arrangements entered into or materially modified on or after March 1, 2011. This change did not have any material impact on the consolidated financial statements.

Impairment of goodwill

On December 17, 2010, the FASB issued ASU 2010-28, the new standard requires entities with a zero or negative carrying value to assess, considering qualitative factors such as those listed in ASC 350, whether it is more likely than not that a goodwill impairment exists. If an entity concludes that it is more likely than not that a goodwill impairment exists, the entity must perform step 2 of the goodwill impairment test. This change did not have any material impact on the consolidated financial statements.

Intangible assets, goodwill and other

In August 2011, the FASB issued Accounting Standards Update No. 2011-08, Intangibles – Goodwill and Other, which discusses the new Qualitative Assessment Option for testing goodwill impairment. Under this update, the Company may first assess qualitative factors to determine whether it is necessary to perform the two-step goodwill impairment test. If the assessment resulted in more than 50% likelihood that the fair value of a reporting unit is less than the carrying amount, then the Company must continue to apply the two-step impairment test. If the fair value exceeds the carrying amount, then neither of the two steps in the current Goodwill impairment test is required. The Company adopted the standard, effective February 29, 2012. The impact of the adoption has been described in Note 9.

Fair value measurements

In January 2010, the Financial Accounting Standards Board (the "FASB") issued authoritative guidance to improve disclosures about fair value measurements. This new authoritative guidance became effective for interim and annual periods beginning after December 15, 2009, except for the requirement to separately disclose

purchases, sales, issuances, and settlements in the Level 3 reconciliation, which became effective for interim and annual periods beginning after December 15, 2010. The Company adopted the authoritative guidance to improve disclosures about fair value measurements and the authoritative guidance requiring separate disclosure on purchases, sales, issuances, and settlements in the Level 3 reconciliation in the first quarter of fiscal 2012. The adoption did not have a material impact on the Company's results of operations, financial condition or the Company's disclosures.

FUTURE ACCOUNTING CHANGES

Fair value measurements

In May 2011, the FASB, as a result of work performed with the International Accounting Standards Board ["IASB"], issued authoritative guidance to achieve common fair value measurement and disclosure requirements in U.S. GAAP and International Financial Reporting Standards ["IFRS"]. The guidance is expected to improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. GAAP and IFRS. The guidance presents certain amendments to clarify existing fair value measurements and disclosure requirements such as clarifying the application of the highest and best use and valuation premise concepts, measuring the fair value of an instrument classified in a reporting entity's shareholders' equity and clarifying that a reporting entity should disclose quantitative information about the unobservable inputs used in a fair value measurements that is categorized within Level 3 of the fair value hierarchy. Furthermore, the guidance amends previous literature by requiring additional disclosures about fair value measurements, specifically requesting more information about the valuation processes used for fair value measurements categorized within Level 3 of the fair value hierarchy as well as presenting sensitivity of the fair value measurements to changes in unobservable inputs in Level 3 valuations. The guidance also amends previous literature around measuring the fair value of financial instruments that are managed within a portfolio as well as the application of premiums and discounts in a fair value measurement. The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2011. The Company will adopt the guidance in the first quarter of fiscal 2013 and is currently evaluating the impact that the adoption of this guidance will have on its results of operations, financial condition and disclosures.

Presentation of comprehensive income

On June 16, 2011, the FASB issued ASU 2011-05, which revises the manner in which entities present comprehensive income in their financial statements. The new guidance removes the presentation options in ASC 220 and requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. The ASU does not change the items that must be reported in other comprehensive income. The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2011.

On December 23, 2011, the FASB issued ASU 2011-12, which defers certain provisions of ASU 2011-05. One of ASU 2011-05's provisions required entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented (for both interim and annual financial statements). Accordingly, this requirement is indefinitely deferred by ASU 2011-12 and will be further deliberated by the FASB at a future date. The Company will adopt the guidance in the first quarter of fiscal 2013 and is currently evaluating the impact that the adoption of this guidance will have on the presentation of comprehensive income.

3. MERGERS, ACQUISITIONS AND OTHER RELATED ACTIVITI ES

Dragonwave HFCL India Private Limited

On March 10, 2011, DragonWave and Himachal Futuristic Communications Ltd. (HFCL) finalized the incorporation of DragonWave HFCL India Private Limited [DW-HFCL]. DragonWave invested $560 in return for 50.1% ownership of the newly formed company. The results of the newly formed subsidiary have been consolidated in the financial statements of the Company as of March 10, 2011. The Company is consolidating the results of DW-HFCL because they have majority control and hold substantive participating rights in the operations of DW-HFCL.

Non-controlling interest consists of the minority owned portion of DragonWave HFCL India Private Limited.

Prior Year Acquisition

On October 13, 2010, the Company acquired all of the outstanding shares of Axerra Networks Inc. ("Axerra"), a leader in pseudowire technology, under a share purchase agreement dated October 13, 2010. The total potential purchase price was up to $25,000 which included $9,500 paid in cash on October 13, 2010 and a potential earn-out of $15,500, based on additional sales performance over the subsequent 16 months, which could have been paid-out in either cash, or the Company's shares at the Company's option. As at the purchase date, the Company recorded $23,770 for the purchase which included cash consideration of $9,500 and the potential earn-out of $15,500 discounted to $14,270 using a risk-free rate of return, adjusted for a risk premium.

The acquisition was accounted for in accordance with ASC 805, where the deemed purchase price was allocated to the underlying tangible and identifiable assets and liabilities acquired based on their respective fair values on the acquisition date, with any excess purchase price allocated to goodwill. The results of operations of the acquired business were consolidated with those of the Company effective October 14, 2010.

3. MERGERS, ACQUISITIONS AND OTHER RELATED ACTIVITI ES (Continued)

The estimated fair values of the assets acquired and liabilities assumed in the Axerra acquisition were as follows:

The Company allocated $14,525 to intangible assets, including customer relationships and developed technology based on the relative fair values at the date of purchase. These intangible assets are being amortized over their estimated useful lives of 8 years and 6 years, respectively. The useful lives of the intangible assets were determined as the period of time over which the assets are anticipated to contribute to the Company's future cash flows. None of the goodwill and intangible assets are deductible for tax purposes.

The primary reason for the acquisition, and the factors that contributed to the recognition of goodwill, related to Axerra's position as a leader in pseudowire technology, and its product portfolio that allows carriers to address the increasing need to carry legacy TDM traffic over a packet based network.

5. TRADE RECEIVABLES

The Company is exposed to credit risk with respect to trade receivables in the event that its counterparties do not meet their obligations. The Company minimizes its credit risk with respect to trade receivables by performing credit reviews for each of its customers.

The Company's allowance for doubtful accounts reflects the Company's assessment of collectability across its global customer base. The Company defines past due based on agreed upon terms with each individual customer. The following table illustrates the balances which are at least 1 day past due and the allowance for doubtful accounts deemed appropriate.

As at February 29, 2012, two customers exceeded 10% of the total receivable balance. These customers represented 37% of the trade receivables balance. [February 28, 2011 – two customers represented 31% of the trade receivables balance].

Included in general and administrative expenses is $215 related to bad debt expense for the year ended February 29, 2012 respectively [year ended February 28, 2011 – $122].

6. INVENTORY

Inventory is comprised of the following:

Cost of sales for the year ended February 29, 2012 was $29,255 [year ended February 28, 2011 – $67,460], which included $27,180 [year ended February 28, 2011 – $60,351] of costs associated with inventory. The remaining costs of $2,075 [year ended February 28, 2011 – $7,190] related principally to freight, warranty and other direct costs of sales.

For the year ended February 29, 2012, the Company recognized an impairment loss on inventory of $2,020 [year ended February 28, 2011 – $3,285].

9. INTANGIBLE ASSETS AND GOODWILL (Continued)

For the year ended February 29, 2012, the Company recognized amortization of intangible assets of $1,986 and [year ended February 28, 2011 – $893]. The Company estimated that it will recognize $1,817, $1,793, $1,216, $607, and $472 respectively for the next five succeeding years.

During the current fiscal year, the Company performed an analysis of its intangible assets in order to determine whether the carrying value of those assets exceeded the estimated future cash flows expected to result from the use or disposition of those assets. Based upon this analysis, management of the Company determined that the carrying value of the intangible assets were in excess of the estimated future cash flows expected to result from their use or disposition. In each case where the fair value of the asset was less than the carrying value, the Company wrote the asset down to its fair value and recorded a corresponding impairment charge. As a result, the Company has recorded an impairment charge on intangible assets of $8,315 during the nine months ended February 29, 2012.

Goodwill

The goodwill impairment test is a three-step process which requires management to make judgmental assumptions regarding fair value. The first step in the impairment test is to assess qualitative factors to determine whether it is necessary to perform the two-step goodwill impairment test. Because the Company impaired its intangible assets with finite lives, the Company believed there were qualitative factors in-place that would suggest that the subsequent two steps of the goodwill impairment test would need to be performed. The second step consisted of estimating the fair value of the Company's aggregated reporting unit using the market value of our common stock as at February 29, 2012, multiplied by the number of outstanding common shares (market capitalization). Management compared the estimated fair value of the reporting unit to its carrying value which includes goodwill. The results of the initial market capitalization test produced results which were above the aggregated reporting unit carrying value; the third step was not required.

10. ACCOUNTS PAYABLES AND ACCRUED LIABILITIES

Accounts Payable and Accrued Liabilities are apportioned as follows:

Warranty accrual:

Within its accrued liabilities, the Company records a liability for future warranty costs based on management's best estimate of probable claims within the Company's product warranties. The accrual is based on the terms of the warranty which vary by customer, product, or service and historical experience. The Company regularly evaluates the appropriateness of the remaining accrual.

developed with funds provided by the OCS, up to an amount equal to 100% of the OCS grants, bearing interest at the rate of LIBOR. The obligation to pay these royalties is contingent on actual sales of the products and in the absence of such sales, no payment is required.

During the fiscal year the Company adjusted the contingent royalty liability based on a change in estimate. A corresponding gain of $1,850 was made to recognize the change in estimate in the consolidated statement of operations and comprehensive income (loss) in the year ended February 29, 2012. The fair value represents the discounted, most probable obligation to the Company. After consideration of the liability currently recognized in the consolidated balance sheet of $1,711, the Company has a maximum potential obligation of an additional $13,938.

16. INCOME TAXES (Continued)

The Company's deferred tax assets and liabilities include the following significant components:

As at February 29, 2012, the Company had cumulative tax loss carryforwards in the following jurisdictions: Canada – $52,847, Israel – $44,637, United States – $9,237.

The losses in Canada expire starting in Fiscal 2029 until Fiscal 2032. The losses in Israel can be carried forward indefinitely. The losses in Israel were obtained by the Company as a result of the acquisition of Axerra Networks, Inc. in October 2010. Income tax benefits relating to the losses in Canada and Israel have not been recognized in the consolidated financial statements as the recognition requirements under the liability method of accounting for income taxes have not been met.

The losses in the U.S. expire between 2021 and 2032. Internal Revenue Code Section 382 imposes an annual limitation on the use of a company's net operating loss carryforwards when a company has an ownership change. The acquisition of Axerra Networks, Inc by the Company resulted in an ownership change as understood by Section 382. As a result, the annual restriction of the amount of losses of Axerra Networks, Inc that may be used has been calculated as $521.

The net change in the valuation allowance over the prior year of $13,789 relates primarily to the research and development tax credits in Canada and tax losses in the United States, as management believes it is more likely than not that the related deferred tax assets will not be realized. The valuation allowance related to deferred tax assets in the United States increased during the year by $1,777 due to a change in circumstances that has caused a change in judgement about the amount of deferred tax assets that will be realized in future.

As at February 29, 2012, the Company had $12,327 of investment tax credits available to reduce future federal Canadian income taxes payable. These investment tax credits begin to expire in 2021. In addition, the Company had provincial research and development tax credits of $1,782, which are available to reduce future provincial income taxes payable. These provincial tax credits begin to expire in 2029. The tax benefit of the federal and provincial tax credits has not been recognized in the consolidated financial statements.

16. INCOME TAXES (Continued)

The Company had a transitional tax credit of $1,079, arising from Federal/Ontario Corporate Tax Harmonization, which is available to reduce future Ontario income tax and expires in 2014. A tax benefit for this credit has not been recognized in the consolidated financial statements.

During the year, the Company recorded an increase to contributed surplus in the amount of $189 that resulted from an adjustment made to prior year tax returns. The adjustment made to prior year tax returns resulted in a tax benefit that exceeded the related deferred tax asset. According to US GAAP, the excess tax benefit is required to be recorded to contributed surplus.

As of February 29, 2012, the Company has not recorded any liabilities associated with unrecognized tax benefits.

The Company remains subject to examination by tax authorities in Canada for tax years 2005 to 2012 and in the United States for tax years 2009 to 2012.

No deferred income taxes have been provided on undistributed earnings or relating to cash held in foreign jurisdictions, as the Company has determined that any income or withholding taxes on repatriation would not be significant.

17. RELATED PARTY TRANSACTIONS

The Company leases premises from a real estate company controlled by a member of the Board of Directors. During the year ended February 29, 2012, the Company paid $1,705 [year ended February 28, 2011 – $1,463], relating to the rent, operating costs, and leasehold improvements associated with this real estate, and the value owing for net purchases at February 29, 2012 was $3 [February 28, 2011 – $30].

The Company also purchased services from a company controlled or significantly influenced by a Board member. Total net services purchased for the year ended February 29, 2012 was $119 [year ended February 28, 2011 – $250]. These amounts have been allocated amongst various expense accounts and prepaid expenses.

During the prior year the Company purchased products and services from a company controlled or significantly influenced by a Board member in the amount of $2,794. The company ceased to be a related party on May 28, 2010.

Details of the related party transaction amounts included in the consolidated statements of operations and comprehensive income (loss) are as follows:

All transactions are in the normal course of business and have been recorded at the exchange amount.

18. FINANCIAL INSTRUMENTS

Financial instruments are classified into one of the following categories: held-for-trading, held-to-maturity, available-for-sale, loans and receivables, or other financial liabilities.

Fair Value

The following table summarizes the carrying values of the Company's financial instruments:

Cash and cash equivalents, restricted cash, short term investments, trade receivables, other receivables, accounts payable and accrued liabilities are short term financial instruments whose fair value approximates the carrying amount given that they will mature shortly. As at the consolidated balance sheet dates, there are no significant differences between the carrying values of these items and their estimated fair values. All financial instruments have been measured using Level 1 inputs.

Interest rate risk

Cash and cash equivalents and short term investments with fixed interest rates expose the Company to interest rate risk on these financial instruments. Interest income of $393 was recognized during the year ended February 29, 2012 on the Company's cash, cash equivalents and short term investments [year ended February 28, 2011 – $233].

Credit risk

In addition to trade receivables and other receivables, the Company is exposed to credit risk on its cash and cash equivalents, restricted cash, and short term investments in the event that its counterparties do not meet their obligations. The Company does not use credit derivatives or similar instruments to mitigate this risk and, as such, the maximum exposure is the full carrying value or fair value of the financial instrument. The Company minimizes credit risk on cash and cash equivalents and short term investments by transacting with only reputable financial institutions and customers.

18. FINANCIAL INSTRUMENTS (Continued)

Foreign exchange risk

The following table summarizes the currency distribution of the Company's financial instruments in US dollars, as at February 29, 2012 and February 28, 2011:

Foreign exchange risk arises because of fluctuations in exchange rates. The Company does not currently use derivative financial instruments to mitigate this risk.

If the US dollar had appreciated 1% against all foreign currencies at February 29, 2012, with all other variables held constant, the impact of this foreign currency change on the Company's foreign denominated financial instruments would have resulted in a decrease in after-tax net income of $67 for the year ended February 29, 2012 [year ended February 28, 2011 – $84], with an equal and opposite effect if the US dollar had depreciated 1 percent against all foreign currencies at February 29, 2012.

Liquidity risk

A risk exists that the Company will not be able to meet its financial obligations as they become due. Based on the Company's recent performance, current revenue expectations and strong current ratio, management believes that liquidity risk is low.

19. SEGMENTS AND GEOGRAPHICAL INFORMATION

The Company operates in one reportable segment – broadband wireless backhaul equipment.

21. EXPENSES

22. SUBSEQUENT EVENTS

Settlement of Contingent Consideration

On October 13, 2010, the Company acquired all of the outstanding shares of Axerra Networks Inc. ["Axerra"], a leader in pseudowire technology, under a share purchase agreement dated October 13, 2010. The total potential purchase price was up to $25,000 which included $9,500 paid in cash on October 13, 2010 and a potential earn-out of $15,500, based on sales performance over the following 16 months, which could have been paid-out in either cash, or the Company's shares at the Company's option.

The earn-out phase of the acquisition was completed on February 13, 2012 and, based on actual sales, the earn-out amount was determined to be $1,884. Subsequent to February 29, 2012, at DragonWave's option, $84 of the earn-out was paid in cash, and the balance of the earn-out was paid with 400,983 common shares of DragonWave, valued at $4.49 per common share based on a 20 day volume weighted average price.

During the year ended February 29, 2012, the Company recognized $557 of accretion expense with regards to the contingent consideration liability [year ended February 28, 2011 – $352].

• ability to successfully complete and integrate acquisitions of products or businesses, including the proposed acquisition of Nokia Siemens Networks, into our existing product lines and businesses and other risks associated with acquisitions;

• dependence on the development and growth of the market for high-capacity wireless communications services; • reliance on a small number of customers for a large percentage of revenue; • intense competition from several competitors; • competition from indirect competitors; • a history of losses; • dependence on the ability to develop new products and enhance existing products; • our ability to successfully manage growth; • dependence on establishing and maintaining relationships with channel partners; • quarterly revenue and operating results which are difficult to predict and can fluctuate substantially; • the impact of the general economic downturn on our customers; • disruption resulting from economic and geopolitical uncertainty; • currency fluctuations; • exposure to credit risk for accounts receivable; • pressure on our pricing models from existing and potential customers and as a result of competition; • the allocation of radio spectrum and regulatory approvals for our products; • our customers' ability to secure a license for applicable radio spectrum; • changes in government regulation or industry standards that may limit the potential market for our products; • risks associated with possible loss of our foreign private issuer status; • risks and expenses associated with being a public company; • reliance on outsourced manufacturing and third party component suppliers; • our ability to protect our own intellectual property and potential harm to our business if we infringe the intellectual property rights of others; • risks associated with software licensed by us; • a lengthy and variable sales cycle; • dependence on our ability to recruit and retain management and other qualified personnel; • exposure to risks resulting from international sales and operations, including the requirement to comply with export control and economic sanctions laws; and • product defects, product liability claims, or health and safety risks relating to wireless products.

The risks and uncertainties listed above, and the impact of those risks and uncertainties materializing, may be materially increased by the completion of the anticipated acquisition by us of the microwave transport business of Nokia Siemens Networks. In particular, material risks and uncertainties following closing of the acquisition will include, without limitation:

• reliance on Nokia Siemens Networks for a large percentage of our revenues;

• increased cash requirements to fund acquired operations, and associated requirements to comply with debt financing covenants with our lenders, which should be understood in light of our history of losses noted above;

• increased exposure to global currency fluctuations; • increased regulatory compliance obligations, including financial reporting obligations associated with completing a significant acquisition; and • risks associated with acquisitions generally as detailed in our most recently filed Annual Information Form.

Forward-looking statements relating to the anticipated acquisition by us of the microwave transport business of Nokia Siemens Networks are also based on certain assumptions, including the parties' beliefs regarding the industry and markets in which the parties operate; successful completion of the proposed transaction; and expectations regarding potential synergies and prospects for the business if the transaction is closed. The proposed transaction is subject to risks, including: the risks that the parties will not proceed with the transaction for any reason; that the ultimate terms of the transaction will differ from those that are currently contemplated; that if the transaction is completed, that expected synergies will not materialize; that unexpected costs will be incurred to integrate the business; or that end-customer demand will not meet expectations. In particular, the completion of the proposed transaction is subject to a number of terms and conditions, including, without limitation, no occurrence of a material adverse effect. These conditions to the transaction may not be satisfied, in which case the proposed transaction could be modified, restructured or terminated. Other risks relating to Nokia Corporation including Nokia Siemens Networks are specified in Nokia's annual report Form 20-F for the year ended December 31, 2011 under item 3D "Risk Factors".

Readers are also referred to "Risk Factors" in the Company's most recently filed AIF, and in particular to risks detailed therein associated with acquisitions generally. The Company's most recently filed AIF is available at http://www.sedar.com and http://www.sec.gov/edgar/searchedgar/companysearch.html . Although we have attempted to identify important factors that could cause our actual results to differ materially from our expectations, intentions, estimates or forecasts, there may be other factors that could cause our results to differ from what we currently anticipate, estimate or intend.

For the three and twelve months ended February 29, 2012 Tables are expressed in USD $000's except share and per share amounts unless otherwise indicated

The change in the results between 2012, 2011 and 2010 can be attributed to a number of factors including:

1) The revenue decrease over the disclosed periods relates primarily to lower revenue levels from a US-based national carrier.

2) Gross profit was impacted in the fourth quarter of fiscal 2012 by a $1.7 million inventory provision taken against finished goods inventory of older technologies which are increasingly being replaced. The gross profit percentages when compared over the time period between fiscal 2010, fiscal 2011 and fiscal 2012 have remained relatively consistent when adjusted for inventory provisions despite the decrease in volumes (gross profit percentage adjusted for inventory provisions: fiscal 2012 — 40%; fiscal 2011 — 46%; fiscal 2010 — 42%).

3) Our operating expenses have increased over the periods presented as a result of the following factors: the acquisition of Axerra Networks, Inc. ("Axerra") in the third quarter of fiscal 2011; the relatively weaker USD in fiscal 2012, which caused the largely Canadian dollar ("CAD") based operating costs to be reflected as more expensive in USD; and lower overall production volumes. Because we are operating below capacity more of the fixed costs are impacting operating expenses versus cost of goods sold.

SELECTED CONSOLIDATED QUARTERLY FINANCIAL INFORMATI ON

The following table sets out selected financial information for each of our most recent eight fiscal quarters. In the opinion of management, this information has been prepared on the same basis as our audited consolidated financial statements, and all necessary adjustments have been included in the amounts stated below to present fairly the unaudited quarterly results when read in conjunction with our consolidated financial statements and related notes thereto.

Historically, our operating results have fluctuated on a quarterly basis and we expect that quarterly financial results will continue to fluctuate in the future. The results of operations for interim periods should not be relied upon as an indication of the results to be expected or achieved in any future period or any fiscal year as a whole. Fluctuations in results relate to the project nature of the network installations of our end-customers. In addition, results may vary as a result of the timing of staffing, infrastructure additions required to support growth, and material costs required to support design initiatives. Operating results may not follow past trends for other reasons, including strategic decisions by us such as acquisitions of complementary products or businesses.

function as a wireless extension to an existing fiber and global optic core telecommunications network. The principal application for our products is the backhaul function in a wireless communications network.

The key messages surrounding our results of operations for the fourth quarter and full year of fiscal 2012 when comparing those results to the same periods in the previous fiscal year include the following:

• Revenue decreased by $6.0 million between the fourth quarter of fiscal 2012 and the fourth quarter in the previous fiscal year and by $72.4 million when comparing the revenues for the full twelve months of fiscal 2012 and the same twelve month period in fiscal 2011. The primary factors contributing to the revenue changes are: • A decrease in sales to a US-based service provider (fourth quarter decrease — $1.9 million; full year decrease — $65.6 million).

• A decrease in sales to a US-based Multiple System Operator ("MSO") (fourth quarter decrease — $3.6 million; full year decrease — $4.7 million).

• Although we achieved growth in sales from certain North American distributors and recognized a new greater than 10% of sales customer in Europe,

reduction in sales in other areas eroded those gains resulting in a net decrease to sales (fourth quarter decrease — $0.5 million; full year decrease — $2.1 million).

• Gross profit percentage was examined both before and after the inventory provision taken in the fourth quarter of both fiscal 2012 and fiscal 2011. Inventory provisions taken in the fourth quarter of fiscal 2012 had a 19% negative impact on the gross profit percentage for the quarter and a 4.4% impact for the full year of fiscal 2012 (impact of inventory provisions on the fourth quarter of fiscal 2011 — 13.5%; impact for the full year — 2.7%). Excluding the inventory provisions in both years, the gross profit percentage was 40.4% in fiscal 2012 and 45.6% in fiscal 2011.

• Operating expenses increased by $0.6 million for the fourth quarter of fiscal year 2012 when compared to the fourth quarter of 2011, and by $7.2 million when comparing to the full year of fiscal 2012 to the same period in the previous fiscal year. The key factors contributing to the changes include:

• A reduction in the estimated liability associated with the earn-out related to the Axerra acquisition, as well as other Axerra related intangible asset impairment charges and accretion expenses, resulted in a gain on the profit and loss statement (fourth quarter — $0.6 million; full year gain — $6.2 million).

• As a result of the factors described above, we incurred a net loss applicable to shareholders of $13.4 million in the three months ended February 29, 2012 and a $33.5 million net loss applicable to shareholders in the twelve months ending on the same date.

• Cash (including cash and cash equivalents, short term investments and restricted cash) decreased by $7.2 million when comparing the three months ended February 28, 2011 to the three months ended February 29, 2012. Between February 28, 2011 and our year ended February 29, 2012 we used $36.7 million of cash. Our cash balance at February 29, 2012 was $53.0 million.

Our Priorities:

Our predominant focus is on revenue growth, both organically and through continued efforts to identify appropriate acquisition targets and partnerships.

The Merger & Acquisition Growth Strategy

Acquisition of NSN's Microwave Transport Business

This section includes forward-looking statements related to our planned acquisition of the microwave transport business of Nokia Siemens Networks ("NSN"). See "Forward Looking Statements" and "Risks and Uncertainties."

On November 4, 2011, we announced the planned acquisition of the microwave transport business of NSN (the "Business") pursuant to a Master Acquisition Agreement dated as of November 4, 2011 between Nokia Siemens Networks B.V., DragonWave and our wholly-owned subsidiary DragonWave S.A.R.L. The details of proposed acquisition of the Business were disclosed in the press release of the Corporation dated November 4, 2011 and in a material change report of the Corporation dated November 14, 2011.

On May 3, 2012 we announced that we have reached an amended agreement with NSN for DragonWave's acquisition of NSN's microwave transport business including its associated operational support system (OSS) and related support functions. The amended agreement simplifies the transaction, provides both companies with greater flexibility to adapt to changing market environments and enhances the delivery of customer-valued product features, while minimizing disruption in the team. The planned closing date is June 1, 2012, to align with NSN's fiscal calendar.

Under the terms of the amended agreement, we will become the preferred strategic supplier of packet microwave and related products to NSN and the two companies will jointly coordinate technology development activities. The NSN employees based in Italy will not transfer to DragonWave under the revised agreement. We will enter into a services agreement with NSN (Italy) for outsourced R&D, product management, sales support and operations functions. The services agreement contemplates the potential transfer of the Italian business including its employees to DragonWave at the end of the services agreement. This will enhance our ability to continue to deliver on critical customer deliveries.

We believe the acquisition and associated supply agreements will accelerate innovation in backhaul products, supporting world-class microwave solutions for mobile operators. Under the terms of the amended agreement, NSN retains responsibility for its existing solution sales and associated services for microwave

transport, while DragonWave is responsible for the microwave transport product line, including R&D, product management and operation functions.

The Business will be acquired through one of DragonWave's wholly-owned subsidiaries, DragonWave S.à.r.l. and other indirect wholly-owned subsidiaries. The purchase price paid on closing will include approximately € 11.8 million in cash, subject to customary purchase price adjustments, and common shares of DragonWave with a value of € 5.0 million which are subject to a lock-up restricting sale or disposition of the shares (subject to customary exceptions). DragonWave will also acquire other assets under capital asset lease or other deferred sale arrangements with a value of approximately €3.6 million over 24 months. In keeping with the simplification of the transaction, the sales performance based earn-out payments have been eliminated.

We will finance the transaction through a combination of cash on our balance sheet and increased debt facilities provided by Comerica Bank and Export Development Canada.

The acquisition of NSN's Chinese operations is expected to be formally completed in the second half of 2012, once all of the licenses and permissions to do so are in place. Approximately 130 employees of NSN based in Shanghai will transfer to DragonWave at that time. We believe that this acquisition provides transferring employees with attractive new opportunities in a solid, technologically advanced company, with its focus on their core areas of expertise.

We believe that the acquisition will be a "significant acquisition" for us under applicable securities laws and, accordingly, we will file a Business Acquisition Report within 75 days of closing.

Axerra

During the third quarter of fiscal 2011 we acquired Axerra, a leader in pseudowire technology. We believe that Axerra's complementary technology and existing customer base will continue to integrate well with our own. The purchase agreement was structured such that we acquired all of the outstanding shares of Axerra. The total potential purchase price was up to $25.0 million which included $9.5 million paid in cash on October 13, 2010, and a potential earn-out of $15.5 million based on sales performance over a 16 month period (between October 13, 2010 and February 13, 2012). Axerra has historically had a single customer which accounted for a large percentage of its revenue. This customer is a US based MSO which accounted for more than 80% of its revenue. Sales to this customer have dropped significantly since the acquisition date due primarily to uncertainty surrounding merger discussions between major US service providers. Between the date of the acquisition and February 29, 2012, Axerra recognized revenue of $11.5 million. On December 19, 2011, DragonWave announced that it had eliminated 38 positions from its Israeli operations. The staff reduction, which included both full time and contract staff, is intended to better align the company's global sales force with existing DragonWave resources as well as the planned acquisition of NSN's microwave transport business. DragonWave will continue to support R&D, customer support, finance, and operations functions in Israel.

The earn-out phase of the acquisition was completed on February 13, 2012 and, based on actual sales, the earn-out amount was determined to be $1.9 million. Subsequent to February 29, 2012, at DragonWave's option, $84 thousand of the earn-out was paid in cash, and the balance of the earn-out was paid with 400,983 common shares of DragonWave, valued at $4.49 per common share based on a 20 day volume weighted average price.

On February 27, 2012, we merged Axerra with and into our wholly-owned subsidiary, DragonWave Corp., with DragonWave Corp. surviving the merger.

HFCL — India Update

The market opportunities for wireless backhaul in India continue to be a strong area of interest for DragonWave. Through our 50.1% owned subsidiary, jointly owned with Himachal Futuristic Communications Ltd. ("HFCL"), we are trialing our equipment with major internet service providers in the country. The time from first discussions with a new carrier to the receipt of purchase orders, can often take eighteen months or longer, as they plan their network and acquire sites. We remain optimistic about DragonWave — HFCL's prospects for deployments in the country.

The Organic Growth Strategy

We continue to believe strongly that our growth will come through relationships with partners in a variety of regions throughout the world. We are supporting trials of our equipment at original equipment manufacturer ("OEM") locations in the United States and Europe and it is through these relationships that we believe we can best take advantage of the major network builds and upgrades planned by national carriers. We also continue to work closely with our distributors and resellers who provide an important link into regional network operators.

We believe strongly that to successfully attract major service providers we need to design products that address the economic pressures of operating networks. Our research and development focuses heavily on products that maximize spectral efficiency and bandwidth capacity, while minimizing operating costs. In addition, we are working diligently to remain a leader with innovative solutions that meet the requirements for smaller cell sizes and data traffic management.

Revenue and Expenses

Revenue

We consider that we have one reportable segment, namely, broadband wireless backhaul equipment. The vast majority of our sales come from the shipment of equipment either through direct sales, through sales to distributors, or through OEMs.

We evaluate the revenue performance of this segment over three main geographic regions. The table below breaks down the revenue earned by region for the three month period ending February 29, 2012 and the twelve month period ending February 29, 2012 and compares these figures to the same period in the prior fiscal year.

Cost of Sales and Expenses

A large component of our cost of sales is the cost of product purchased from outsourced manufacturers. In addition to the cost of product payable to outsourced manufacturers, we incur expenses associated with final configuration, testing, logistics and warranty activities. Final test and assembly for the links sold by us is carried

on both at our premises and at the premises of our contract manufacturers. We use primarily the services of three outsourced contract manufacturers with locations in North America, Israel and Malaysia.

Research and development costs relate mainly to the compensation of our engineering group and the material consumption associated with prototyping activities.

Selling and marketing expenses include the remuneration of sales staff, travel and trade show activities and customer support services.

General and administrative expenses relate to the remuneration of related personnel, professional fees associated with tax, accounting and legal advice, and insurance costs.

Occupancy and information systems costs are related to our leasing costs and communications networks and are accumulated and allocated, based on headcount, to all functional areas in our business. Our Ottawa based facilities are leased from a related party that is controlled by one of our directors and shareholders. Our management believes the terms of the lease reflect fair market terms and payment provisions.

The three most significant factors contributing to the decline in gross profit in the fourth quarter of fiscal 2012, and correspondingly in the full year's gross profit percentage when compared to the same periods in the previous fiscal year, were: i) the inclusion of a $1.7 million inventory provision in the fourth quarter of fiscal 2012, ii) higher costs associated with a specific European contract, and iii) lower sales volumes.

The inventory provision was primarily taken against certain finished goods AirPair inventory which has become less marketable as comparable Quantum variants have been developed.

Customer and product mix changes continue to result in variances in margin each quarter. Higher costs associated with a specific European customer in the fourth quarter of fiscal 2012 placed downward pressure on margin in the period.

Finally lower sales volumes have impacted the gross margin in a variety of ways including reducing our ability to get favourable material pricing. In addition, lower revenue levels have increased overhead as a percentage of revenue because our fixed costs are leveraged over fewer units of output. We continue to reduce costs wherever possible to align the business with current sales volume levels.

Expenses

Three and Twelve Months Ended February 29, 2012 vs. Three and Twelve Months Ended February 28, 2011

Approximately 90% of our operating expenses including compensation-related spending, rent, and professional fees are paid in non-USD currencies. For financial statement presentation purposes, these costs are translated into USD. As the USD weakens, the value of these expenses in USD terms increases. The CAD, which accounts for more than 60% of all expenditures, strengthened significantly during the reporting period

Changes to General and Administrative Expenses

Government Assistance

The $0.9 million credit for the twelve months ending February 29, 2012 reflects research and development funding received through the Office of the Chief Scientist ("OCS") of the Ministry of Industry and Trade in Israel. In connection with this funding, we will be required to pay royalties at the rate of 3% — 3.5% of sales of products developed with funds provided by the OCS, up to an amount equal to 100% of the OCS grants, bearing interest at the rate of LIBOR. The obligation to pay these royalties is contingent on actual sales of the products and in the absence of such sales, no payment is required. This funding did not exist prior to the acquisition of Axerra and therefore was present in our fiscal 2011 financial statements for only the time period from October 13, 2010 to February 28, 2011. There was no funding in the fourth quarter of fiscal 2012 because we have decided not to pursue additional OCS funding at this time.

Amortization of Intangible Assets

In fiscal 2012, the amount in the table above reflects both the amortization of the intangible assets acquired with the acquisition of Axerra and the amortization of computer software. As a consequence of the revaluation

of the intangible assets acquired with the acquisition of Axerra, which took place in the second quarter of fiscal 2012, amortization expense was lower in the second half of fiscal 2012 than it was in the first half of the same fiscal year. The amortization of intangible assets acquired with the acquisition of Axerra impacted only the three months ended February 28, 2011 and not the full twelve month comparative period.

Accretion (Expense)

As part of the acquisition of Axerra, we agreed to pay a potential earn-out of $15.5 million based on sales performance over a sixteen month period. The potential liability that this reflects was recorded on the balance sheet at the time of the acquisition at its fair value using a discount rate equal to the risk free rate of return adjusted for a risk premium.

The earn-out phase of the acquisition of Axerra was completed on February 13, 2012 and, based on sales the earn-out amount was determined to be $1.9 million. Subsequent to February 29, 2012, at DragonWave's option, $84 thousand of the earn-out was paid in cash, and the balance of the earn-out was paid with 400,983 common shares of DragonWave, valued at $4.49 per common share based on a 20 day volume weighted average price.

During the three months and twelve months ended February 29, 2012 we recognized $38 thousand, and $650 thousand of accretion expense that related to the contingent consideration and OCS liabilities.

Interest

Interest revenue reflects the earnings on the highly liquid low risk investments made by us during the period in question. Interest rates remain low, and returns on investment are therefore minimal. At February 29, 2012 all short term investments had been converted into cash in preparation for the possible requirements of the contemplated Nokia Siemens transaction.

We make short term investments which carry a fixed yield and term to maturity. Because these investments are reflected on the balance sheet at their fair value, changes in market interest rates for similar instruments necessitate that the investment is either increased in value or decreased. Because interest rates have decreased since the time that the fixed yield investment held prior to February 29, 2012 was purchased, an investment gain was recorded.

Impairment of Intangible Assets & Gain on Change in Estimated Liabilities

The amounts identified in the table above relate to the acquisition of Axerra.

During the current fiscal year, we performed an analysis of our intangible assets in order to determine whether the carrying value of those assets exceeded the estimated future cash flows expected to result from the use or disposition of those assets. Based upon this analysis, we determined that the carrying value of the intangible assets were in excess of the estimated future cash flows expected to result from their use or disposition. In each case where the fair value of the asset was less than the carrying value, the Company wrote the asset down to its fair value and recorded a corresponding impairment charge. As a result, we recorded an impairment charge on intangible assets of $8.3 million during the twelve months ended February 29, 2012.

The gain on change in estimate reflects a revaluation of two different liabilities. During the fiscal year the Company adjusted the contingent royalty liability associated with the OCS based on a change in estimate. A corresponding charge of $1.9 million was made to recognize the change in estimate in the consolidated statement of operations and comprehensive income in the year ended February 29, 2012. The second liability adjustment related to the earn-out obligations for DragonWave associated with the acquisition of Axerra. The earn-out phase of the acquisition was completed on February 13, 2012 and, based on sales the earn-out amount was determined to be $1.9 million. During the year ended February 29, 2012, the Company recognized $0.6 million of accretion expense with regards to the contingent consideration liability. During the year ended February 29, 2012 the Company recognized a gain on a change in estimate with regards to the contingent consideration in the amount of $13.3 million. The total of both adjustments was $15.1 million.

Foreign Exchange Gain

The foreign exchange gain recognized in the fourth quarter of fiscal 2012 and the gain recognized in the twelve month period ending February 29, 2012 resulted from the translation of monetary accounts denominated

Income Taxes Expense (Recovery)

Income tax recovery for 2012 was ($0.1) million, compared to a tax expense of $0.4 million for the prior year. The year-over-year change relates primarily to the overall operating loss for 2012, the tax benefit of which has not been recognized, as well as recoveries of prior years' taxes during the year resulting from amendments made to prior years' tax returns.

Cash and Cash Equivalents, Restricted Cash and Short Term Investments

As at February 29, 2012, we had $53.0 million in cash and cash equivalents, restricted cash, and short term investments (collectively "Cash") representing an $36.7 million decrease from the Cash balance at February 28, 2011.

Sources and Uses of Cash:

The operating losses (driven by operating expense levels for an organization which was sized to support a larger revenue stream) are the key factor in the cash usage of $7.2 million in the three months ended February 29, 2012 and $36.7 million in the twelve month period ending fiscal 2012.

We limited the growth in non-cash working capital throughout the year, worked hard to collect accounts receivable as quickly as possible and pushed our vendors to accept more favourable payment terms. Growth in inventory levels was also limited in the year. Similarly, investment in capital assets and software was restricted, limited to only $1.2 million in the three months ended February 29, 2012 and in the fiscal year 2012 to $2.7 million.

The proceeds from option exercises provide funds to us. Option exercise prices range from $1.34 to $13.74 and in the three months ended February 29, 2012, 5,414 options were exercised (net proceeds, including

Working Capital

Trade Receivables:

The trade receivables balance decreased by $1.7 million between February 28, 2011 and February 29, 2012 (February 28, 2011 — $11.6 million; February 29, 2012 — $9.9 million). The days sales outstanding in accounts receivable changed, increasing from 69 days at February 28, 2011 to 107 days at February 29, 2012. The increase in the balance and corresponding days sales outstanding was driven by longer payment terms negotiated for special circumstances with certain customers. Our allowance for doubtful accounts provision remains low, accounting for only 0.7% of our accounts receivable balance.

Inventory:

The inventory balance decreased by $1.2 million between February 28, 2011 and February 29, 2012. In the face of lower sales levels, our inventory levels continue to be higher than desired. However, our production inventory is made up of product variants which are continuing to generate significant global interest. Approximately 90% of our inventory relates to our current platforms including Quantum, Fusion, and Horizon Compact. Only a limited portion of our inventory continues to relate to AirPair radios and Duo modems, which are now sold less frequently.

Accounts Payable and Accrued Liabilities:

The accounts payable and accrued liabilities balance decreased from $16.0 million at February 28, 2011 to $ 12.7 million at February 29, 2012. The reduction reflects lower overall purchasing activity as it relates to material purchases for production and engineering prototype development.

Liquidity and Capital Resource Requirements

Based on our recent performance and current revenue expectations, our management believes cash resources will be available to satisfy working capital needs for at least the next 12 months.

Commitments as at February 29, 2012

Future minimum operating lease payments as at February 29, 2012 per fiscal year are as follows:

In the normal course of our business activities, we are subject to claims and legal actions. We recognize a provision for estimated loss contingencies when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In management's opinion, adequate provisions have been made for all current and future claims.

Royalty Commitments

Under research and development agreements assumed in connection with the acquisition of Axerra, the Company received and accrued participation payments from the OSC in the amount of $0.9 million in the year ended February 29, 2012. DragonWave is required to pay royalties at the rate of 3% – 3.5% of sales of products developed with funds provided by the OCS, up to an amount equal to 100% of the OCS grants, bearing interest at the rate of LIBOR. The obligation to pay these royalties is contingent on actual sales of the products and in the absence of such sales, no payment is required.

During the fiscal year, the Company adjusted the contingent royalty liability based on a change in estimate. A corresponding charge of $1.9 million was made to recognize the change in estimate in the consolidated statement of operations and comprehensive income in the year ended February 29, 2012. The fair value represents the discounted, most probable obligation of DragonWave. After consideration of the liability currently recognized in the consolidated balance sheet of $1.7 million, the Company has a maximum potential obligation of an additional $13.9 million.

Off-Balance Sheet Arrangements:

(USD in Dollars)

The leases are arranged at market pricing levels in all jurisdictions and the lease periods listed above represent a commitment for the time period indicated. We may or may not be able to sub-lease in these locations should we chose to change locations, and as a result the monthly lease commitments may represent an obligation for the time periods noted above.

We use an outsourced manufacturing model whereby most of the component acquisition and assembly of our products is executed by third parties. Generally, we provide the supplier with a purchase order 90 days in advance of expected delivery. We are responsible for the financial impact of any changes to the product requirements within this period. In some cases when a product has been purchased by a contract manufacturer but not pulled on for a build for an amount of time we provide a deposit against that inventory, but do not take ownership of it.

Our contract manufacturers currently have inventory intended for use in the production of our products, and we have purchase orders in place for raw materials and manufactured products with these contract manufacturers as well. All of this material is considered to be part of the normal production process and is expected to be fully used based on current forecasts and projections. As mentioned previously, we would be responsible for the cost of the material approved to be purchased on behalf of our Company by our contract manufacturers should those forecasts or projections change.

Financial Instruments

Under US GAAP, financial instruments are classified into one of the following categories: held for trading, held-to-maturity, available-for-sale, receivables, or other liabilities.

DragonWave Inc. Management's Discussion and Analysis

For the three and twelve months ended February 29, 2012 Tables are expressed in USD $000's except share and per share amounts unless otherwise indicated

Fair Value

The following table summarizes the carrying values of our financial instruments:

Cash and cash equivalents, restricted cash, short term investments, trade receivables, other receivables, accounts payable and accrued liabilities are short term financial instruments whose fair value approximates the carrying amount given that they will mature shortly. As at the balance sheet date, there are no significant differences between the carrying value of these items and their estimated fair values.

Interest rate risk

Cash and cash equivalents and short term investments with fixed interest rates expose DragonWave to interest rate risk on these financial instruments. Interest income of $0.4 million was recognized during the year ended February 29, 2012 on the Company's cash, cash equivalents and short term investments (year ended February 28, 2011 — $0.2 million).

Credit risk

In addition to trade receivables and other receivables, the Company is exposed to credit risk on its cash and cash equivalents, restricted cash, and short term investments in the event that its counterparties do not meet their obligations. The Company does not use credit derivatives or similar instruments to mitigate this risk and, as such, the maximum exposure is the full carrying value or face value of the financial instrument.

DragonWave Inc. Management's Discussion and Analysis

For the three and twelve months ended February 29, 2012 Tables are expressed in USD $000's except share and per share amounts unless otherwise indicated

Foreign exchange risk arises because of fluctuations in exchange rates. The Company does not currently use derivative financial instruments to mitigate this risk.

If the USD had appreciated 1% against all foreign currencies at February 29, 2012, with all other variables held constant, the impact of this foreign currency change on the Company's foreign denominated financial instruments would have resulted in a decrease in after-tax net income of $67 thousand for the year ended February 29, 2012 (year ended February 28, 2011 — $84 thousand), with an equal and opposite effect if the USD had depreciated 1% against all foreign currencies at February 29, 2012.

Transactions with Related Parties

We lease premises from a real estate company controlled by a member of the Board of Directors. During the three and twelve months ended February 29, 2012, we paid $0.3 million and $1.7 million respectively (three months and twelve months ended February 28, 2011 — $0.3 million and $1.5 million respectively), relating to the rent, operating costs, and leasehold improvements associated with this real estate, and the value owing for net purchases at February 29, 2012 was $3 thousand (February 28, 2011 — $30 thousand). These amounts have been allocated amongst various expense accounts, except for leasehold improvements which have been allocated to property and equipment.

The Company also purchased services from a company controlled or significantly influenced by a Board member. Total net services purchased for the three and twelve months ended February 29, 2012 was nil and $119 thousand respectively (three and twelve months ended February 28, 2011 — nil). This amount was allocated to sales and marketing. The amount related to a one time sponsorship of a sporting event.

All transactions are in the normal course of business and have been recorded at the exchange amount.

Controls and Procedures

At the end of the period covered by MD&A (such period being the fiscal year ended February 29, 2012), an evaluation was carried out under the supervision of, and with the participation of, our management, including our Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO, which are our principal executive officer and principal financial officer, respectively, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")). Based upon that evaluation, our CEO and CFO have concluded that our disclosure controls and procedures were effective as at February 29, 2012 to give reasonable assurance that the information we are required to disclose in reports that we file or submit under the Exchange Act and/or applicable Canadian securities legislation is (i) recorded, processed, summarized and reported, within the time periods specified in the U.S. Securities and Exchange Commission's as well as in accordance with applicable Canadian securities legislation rules and forms, and (ii) accumulated and communicated to management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

DragonWave Inc. Management's Discussion and Analysis

For the three and twelve months ended February 29, 2012 Tables are expressed in USD $000's except share and per share amounts unless otherwise indicated

Our management is also responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f) as well as National Instrument 52-109 of the Canadian Securities Administration. These controls are designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes. Under the supervision and with the participation of our management, including our principal executive officer, our CEO, and principal financial officer, our CFO, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control — Integrated Framework, our management concluded that our internal control over financial reporting was effective as of February 29, 2012.

Ernst & Young LLP, the independent registered public accounting firm that audited the consolidated financial statements filed on SEDAR, has also audited the effectiveness of our internal control over financial reporting as of February 29, 2012, as stated in their report which is included in the financial statements.

Changes in Internal Control over Financial Reporting

During the period covered by this report, no changes occurred in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Critical Accounting Policies and Estimates

Inventory

Inventory is valued at the lower of cost and net realizable value ("NRV"). The cost of inventory is calculated on a standard cost basis, which approximates average actual cost. NRV is determined as the market value for finished goods, replacement cost for raw materials, and finished goods market value less cost to complete for work in progress inventory. Indirect manufacturing costs and direct labour expenses are allocated systematically to the total production inventory.

Revenue recognition

The Company derives revenue from the sale of broadband wireless backhaul equipment which includes embedded software and a license to use said software and extended product warranties. Software is considered to be incidental to the product. Services range from installation and training to basic consulting. Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred and there are no significant remaining vendor obligations, collection of receivables is reasonably assured and the fee is fixed and determinable. Where final acceptance of the product is specified by the customer, revenue is deferred until acceptance criteria have been met.

The Company's business agreements may also contain multiple elements. Accordingly, the Company is required to determine the appropriate accounting, including whether the deliverables specified in a multiple element arrangement should be treated as separate units of accounting for revenue recognition purposes, the fair value of these separate units of accounting and when to recognize revenue for each element. For arrangements involving multiple elements, the Company allocates revenues to each element based on a selling price hierarchy. The selling price for a deliverable is based on its vendor specific objective evidence ("VSOE") if available, third party evidence ("TPE") if VSOE is not available, or estimated selling price ("ESP") if neither

26

DragonWave Inc. Management's Discussion and Analysis

For the three and twelve months ended February 29, 2012 Tables are expressed in USD $000's except share and per share amounts unless otherwise indicated

VSOE nor TPE is available. In multiple element arrangements, revenues are allocated to each separate unit of accounting for each of the deliverables using the relative estimated selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy. The Company has determined the selling price for the undelivered items using VSOE and the delivered items using ESP.

The Company generates revenue through direct sales and sales to distributors. The Company defers the recognition of a portion of sales to distributors based estimated sale returns and stock rotation granted to customers on products in the same period the related revenues are recorded. These estimates are based on historical sales returns; stock rotations and other known factors. During the current fiscal year the Company determined that there was sufficient history to base its estimates on and adapted our policy accordingly.

Revenue associated with extended warranty and advanced replacement warranty is recognized rateably over the life of the contracted service.

Revenue from engineering services or development agreements is recognized according to the specific terms and acceptance criteria as services are rendered.

The Company accrues estimated potential product liability as warranty costs when revenue on the sale of equipment is recognized. Warranty costs are calculated on a percentage of revenue per month based on current actual warranty costs and return experience.

Shipping and handling costs borne by the Company are recorded in cost of sales. Shipping and handling costs charged to customers are recorded as revenue, if billed at the time of shipment. Costs charged to customers after delivery are recorded in cost of sales.

The Company generates revenue through royalty agreements as a result of the use of its Intellectual Property. Royalty revenue is recognized as it is earned.

Advanced Replacement and Extended Warranty

Advanced replacement and extended warranty contracts are services offered by us to our customers as an option to purchase either at the time the goods are shipped or at any time after shipment takes place. Many customers wait to purchase extended warranty coverage until their standard warranty period ends.

Advanced replacement is a service we sell which provides to customers the benefit of having a replacement radio or modem shipped to them when a unit they own has been confirmed by us to be malfunctioning. When the customer receives the replacement radio or modem, they ship the malfunctioning unit back to us. We repair and keep the returned unit.

Standard warranty for customers generally varies between twelve and thirty-six months. Our extended warranty programs enable customers to continue to have repairs and customer support guidance beyond the standard warranty period.

Training

We earn a minimal portion of our total revenue from the sale of training services primarily to installation companies. Only in rare circumstances do we provide or sub-contract installation services (see below), as the customers to whom we sell microwave equipment outsource the installation to specialized companies. As a result, installation training revenue is generally not sold as a bundled service because it is sold to a different customer base. Further, any training that is provided is not essential to the functionality of our product offerings,

For the three and twelve months ended February 29, 2012 Tables are expressed in USD $000's except share and per share amounts unless otherwise indicated

and is thus considered an insignificant deliverable to the overall arrangement and not considered a separate unit of accounting.

Installation

We do not offer installation services. Periodically, a customer may request that we arrange for the installation of the equipment through a fourth party service provider as a condition of the sale. In this case, a separate services agreement is created between DragonWave and the end-user of our equipment, and we sub-contract the installation to a qualified installer. Evidence that the revenue associated with the installation service represents the fair value of the offering is provided by the sub-contracted value of the installation.

Research and development

Our research costs are expensed as incurred. Our development costs other than property and equipment are expensed as incurred unless they meet generally accepted accounting criteria for deferral and amortization. Development costs incurred prior to establishment of technological feasibility do not meet these criteria, and are expensed as incurred.

Income taxes

Income taxes are accounted for using the liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities are determined based on differences between the tax and accounting basis of assets and liabilities as well as for the benefit of losses available to be carried forward to future years for tax purposes that are more likely than not to be realized. Deferred income tax assets and liabilities are measured using enacted tax rates that apply to taxable income in the years in which temporary differences are expected to be recovered or settled. The Company provides a valuation allowance against its deferred tax assets when it believes that it is more likely than not that the assets will not be realized.

The Company determines whether it is more likely than not that an uncertain tax position will be sustained upon examination by the tax authorities. The tax benefit of any uncertain tax position that meets the more-likely-than-not recognition threshold is calculated as the largest amount that is more than 50% likely of being realized upon successful resolution. To the extent a full benefit is not expected to be realized, an income tax liability is effectively established. The Company recognizes accrued interest and penalties on unrecognized tax benefits as interest expense.

Management periodically reviews the Company's provision for income taxes and valuation allowance to determine whether the overall tax estimates are reasonable. When management performs its quarterly assessments of the provision and valuation allowance, it may be determined that an adjustment is required. This adjustment may have a material impact on the Company's financial position and results of operations.

Adoption of United States Generally Accepted Accounting Principles

In February 2008, the Canadian Accounting Standards Board confirmed the transition from Canadian GAAP to International Financial Reporting Standards ("IFRS") for all publicly accountable entities no later than fiscal years commencing on or after January 1, 2011. As a result, management undertook a detailed review of the implications of the Company having to report under IFRS and also examined the alternative available to the Company, as a Foreign Private Issuer in the United States, of filing its primary financial statements in

28

DragonWave Inc. Management's Discussion and Analysis

Canada using U.S. GAAP, as permitted by the Canadian Securities Administrators' National Instrument 51-102, "Continuous Disclosure Obligations".

As a result of this analysis, management determined that the Company would adopt U.S. GAAP as its primary basis of financial reporting commencing March 1, 2011 on a retrospective basis. All comparative financial information contained in the consolidated financial statements to which this MD&A relates has been revised to reflect the Company's results as if they had been historically reported in accordance with U.S. GAAP.

The adoption of U.S. GAAP did not have a material change on the Company's accounting policies or financial results. An adjustment of $154 thousand was made to increase deficit as calculated by Canadian GAAP as at February 28, 2011 due to the adoption of U.S. GAAP.

Under Canadian GAAP, Investment Tax Credits ("ITCs") were recognized as a reduction to the Company's Research and development expense. Under US GAAP, ITC's are recognized as a reduction to Income tax expense. During fiscal 2011, under Canadian GAAP, the Company recognized $0.4 million as a reduction to research and development expense. Under US GAAP, the prior year results were impacted as follows: the Company's income before taxes was adjusted $2.4 million and the Company's tax expense was $0.4 million as opposed to $2.8 million and $0.8 million respectively as was stated under Canadian GAAP. The GAAP difference had no impact on the Company's consolidated Net and Comprehensive Income in the prior fiscal year.

FOR IMMEDIATE RELEASE

FOURTH QUARTER AND FULL FISCAL YEAR 2012

OTTAWA, Canada, May 3, 2012 — DragonWave Inc. (TSX: DWI; NASDAQ: DRWI) a leading global supplier of packet microwave radio systems for mobile and access networks, today announced financial results for the fourth quarter and full fiscal year 2012, ended February 29, 2012. All figures are in U.S. dollars and were prepared in accordance with U.S. generally accepted accounting principles.

Revenue for the fourth quarter of fiscal year 2012 was $9.2 million, compared with $11.8 million in the third quarter of fiscal year 2012 and $15.1 million in the fourth quarter of fiscal year 2011. Revenue from customers within North America was $4.8 million, compared with $8.2 million in the third quarter of this fiscal year and $10.2 million in the fourth quarter of fiscal year 2011. DragonWave had 2 customers who each contributed more than 10% of revenue in the fourth quarter.

Gross margin for the fourth quarter of fiscal year 2012 was 13%, compared with 41% in the third quarter of fiscal year 2012 and 29% in the fourth quarter of fiscal year 2011. The gross margins in the fourth quarters of fiscal years 2012 and 2011 reflect the inclusion of inventory impairment provisions of $1.7 million and $2.0 million respectively.

Revenue for the full fiscal year 2012 was $45.7 million, compared with $118.0 million for the prior fiscal year. Net and comprehensive loss applicable to shareholders for the full fiscal year 2012 was $33.5 million or ($0.94) per basic and diluted share.

• Network deployment plans by DragonWave's existing and potential customers are capital intensive and the timing of such deployments is affected by such customers' access to capital.

• DragonWave faces intense competition from several competitors and if it does not compete effectively with these competitors, its revenues may not grow and could decline. DragonWave also faces competition from indirect competitors.

• DragonWave relies on its suppliers to supply components for its products and the Company is exposed to the risk that these suppliers will not be able to supply components on a timely basis, or at all.

• DragonWave's success depends on its ability to develop new products and enhance existing products.

• DragonWave's quarterly revenue and operating results can be difficult to predict and can fluctuate substantially.

• If DragonWave is required to change its pricing models to compete successfully, its margins and operating results may be adversely affected.

• DragonWave has a lengthy and variable sales cycle.
