Many factors could cause WiLAN's actual results, performance or achievements to differ materially from those expressed or implied by the forward-looking statements, including, without limitation, the following risks: certain WiLAN patents may be found to be invalid, unenforceable and/or not infringed by any specific third party; the Company may be required to establish the enforceability of certain patents in court in order to obtain material licensing revenues; certain WiLAN patents are, and others may be, subject to administrative proceedings that could invalidate or limit the scope of those patents; licensing the Company's patents can take an extremely long time and may be subject to variable cycles; WiLAN is currently reliant on licensees paying royalties under existing licensing agreements and on the additional licensing of its patent portfolio to generate future revenues and increased cash flows; reduced spending by consumers due to the uncertainty of economic and geopolitical conditions may negatively affect the Company; changes in patent or other applicable laws or in the interpretation or application of those laws could materially adversely affect WiLAN; the Company needs to acquire or develop new patents to continue and grow its business; WiLAN may not be able to compete effectively against others to acquire patent assets – any failure to compete effectively could harm its business and results of operations; the Company has made and may make future acquisitions of technologies or businesses which could materially adversely affect it;

WiLAN's acquisitions of patents are time consuming, complex and costly, which could adversely affect its operating results; the Company's quarterly revenue and operating results can be difficult to predict and can fluctuate substantially; WiLAN may require investment to translate its intellectual property position into sustainable profit in the market; the generation of future V-Chip revenues and the likelihood of our signing additional V-Chip licenses could be negatively impacted by changes in government regulation; there can be no assurance as to the payment of future dividends; the Company's ability to recruit and retain management and other qualified personnel is crucial to its ability to develop, market and license its patented technologies; and WiLAN's actual financial results may vary from its publicly disclosed forecasts.
