Investor Presentation May 2018 NYSE:PLT

FORWARD LOOKING STATEMENTS This presentation, together with other statements and information publicly disseminated by Plantronics, contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended , including statements relating to: (i) potential accretion from the transaction; (ii) expected synergies; (iii) benefits to our business that we expect from the combination; (iv) expectations regarding key assumptions and timing; and (v) expectations regarding liquidity, strength of balance sheet and debt repayments, in addition to other matters discussed in this presentation that are not purely historical data. We do not assume any obligation to update or revise any such forward-looking statements, whether as the result of new developments or otherwise. Forward-looking statements involve risks and uncertainties that may cause actual results to differ materially from those contemplated by such statements. Among the factors that could cause actual results to differ materially from those contemplated are: • the ability to: (i) realize expected synergies or operating efficiencies in connection with the proposed transaction within the expected time-frames or not at all and (ii) integrate Polycom's business in a timely and cost-efficient manner without adversely impacting operations, including expectations for new and existing product and services launches; • the effect of the announcement of the proposed transaction on (i) Polycom's and Plantronics' relationships with their respective customers, suppliers and strategic partners and their operating results and businesses generally (including the diversion of management time on transaction-related issues) and (ii) Polycom's and Plantronics' ability to retain and hire key personnel; • the possibility that legal and regulatory enforcement matters that are pending at Polycom may adversely impact the results of the combined company despite indemnification that Siris Capital is providing; • the risk that the financing that Plantronics must receive to consummate the proposed transaction is not obtained on the terms that we anticipate or that it is not available at all, which is magnified by the absence of a financing condition, the risks associated with the increased leverage that the company will have as a result of the transaction, and the risk the company is unable to obtain an affirmation of its credit rating and/or a favorable rating for financing the transaction from rating agencies; • the potential negative effects of the announcement of the proposed transaction on the market price of the company’s common stock, particularly in light of the issuance of stock in the transaction; • uncertainties associated with any aspect of the proposed transaction, including: (i) the risk that not all conditions to closing of the proposed transaction will be satisfied or waived; (ii) uncertainties related to transaction costs; (iii) uncertainties related to the anticipated timing of filings and approvals relating to the proposed transaction; and (iv) the possibility that the proposed transaction does not close when expected or at all; • risks relating to our financial reporting including those resulting from the adoption of new accounting pronouncements and associated system implementation in the context of the transaction, our ability to forecast financial results of the combined company and the risk that reporting system integration could impact our ability to make timely and accurate SEC filings; • the potential impact of the transaction on our future tax rate and payments based on the consolidation of the global group and our ability to quickly integrate foreign operations; • the challenges of integrating the supply chains of the two companies; • the potential that our due diligence did not uncover risks and potential liabilities associated with the acquired business; • our ability to realize and achieve positive financial results projected to arise in the Enterprise market from UC adoption could be adversely affected by a variety of factors including the following: (i) as UC becomes more widely adopted, the risk that competitors will offer solutions that will effectively commoditize our headsets which, in turn, will reduce the sales prices for our headsets; (ii) our plans are dependent upon adoption of our UC solution by major platform providers and strategic partners such as Microsoft Corporation, Cisco Systems, Inc., Avaya, Inc., Alcatel-Lucent, and Huawei, and our influence over such providers with respect to the functionality of their platforms or their product offerings, their rate of deployment, and their willingness to integrate their platforms and product offerings with our solutions is limited; (iii) delays or limitations on our ability to timely introduce solutions that are cost effective, feature-rich, stable, and attractive to our customers within forecasted development budgets; (iv) our successful implementation and execution of new and different processes involving the design, development, and manufacturing of complex electronic systems composed of hardware, firmware, and software that works seamlessly and continuously in a wide variety of environments and with multiple devices; (v) failure of UC solutions generally, or our solutions in particular, to be adopted with the breadth and speed we anticipate (vi) our sales model and expertise must successfully evolve to support complex integration of hardware and software with UC infrastructure consistent with changing customer purchasing expectations; (vii) as UC becomes more widely adopted we anticipate that competition for market share will increase, particularly given that some competitors may have superior technical and economic resources; (vii) (viii) sales cycles for more complex UC deployments are longer as compared to our traditional Enterprise products; (ix) our inability to timely and cost-effectively adapt to changing business requirements may impact our profitability in this market and our overall margins; and (x) our failure to expand our technical support capabilities to support the complex and proprietary platforms in which our UC products are and will be integrated; • volatility in prices from our suppliers, including our manufacturers located in China, have in the past and could in the future negatively affect our profitability and/or market share; • fluctuations in foreign exchange rates; • the bankruptcy or financial weakness of distributors or key customers, or the bankruptcy of or reduction in capacity of our key suppliers; • seasonality in one or more of our product categories; • general global macroeconomic and geo-political conditions, including but not limited to, fluctuations in the stock markets generally; and • slowdowns or downturns in economic conditions generally and in the market for consumer electronics, including voice, video and content solutions. For more information concerning these and other possible risks, please refer to our Annual Report on Form 10-K filed with the Securities and Exchange Commission on May 10, 2017 and other filings with the Securities and Exchange Commission, as well as recent press releases.

USE OF NON-GAAP INFORMATION The financial estimates provided for Polycom’s quarter ended March 31, 2018 are based on Polycom’s preliminary financial results for that period, which have not been audited or reviewed by an independent accounting firm or by Plantronics. Final financial statements are not yet available for such period. Accordingly, the financial estimates provided for Polycom’s quarter ended March 31, 2018 have been prepared on a non-GAAP basis and the results remain subject to completion of Polycom’s quarterly close and review procedures. Guidance for non-GAAP financial measures excludes acquisition related costs, restructuring costs, amortization expense of acquired intangible assets, amortization of goodwill, litigation-related charges including legal settlements, facility exit costs, and certain other non-recurring expenses. Adjusted EBITDA additionally excludes depreciation and amortization, net interest expense, tax expense, charges for excess and obsolete inventories, gains and losses on disposal of property and equipment, and certain other non-recurring expenses. We have not reconciled non-GAAP guidance information presented here because we would not be able to present the various reconciling cash and non-cash items between GAAP and non-GAAP without unreasonable effort. The actual amounts of such reconciling items will have a significant impact on the company’s GAAP financial information. © Plantronics 2018. All Rights Reserved. 3

USE OF NON-GAAP INFORMATION To supplement our condensed consolidated financial statements presented on a GAAP basis, we use non-GAAP measures of operating results, including non-GAAP gross profit, non-GAAP operating income, non-GAAP net income, non-GAAP diluted EPS, and adjusted EBITDA, which exclude certain non-cash expenses and charges that are included in the most directly comparable GAAP measure. These non-GAAP charges are detailed in our GAAP to non-GAAP reconciliation tables shown on slides 52-54 of this presentation. Certain forward looking Non-GAAP measures as projected for FY19 through FY23 exclude items that pertain to future events and are not currently estimable with a reasonable degree of accuracy. Therefore, a reconciliation to GAAP amounts has not been provided. We exclude the expenses detailed in these reconciliation tables from our non-GAAP measures primarily because Plantronics’ management does not believe they are part of our target operating model. We believe that the use of non-GAAP financial measures provides meaningful supplemental information regarding our performance and liquidity and helps investors compare actual results with our long-term target operating model goals. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting and analyzing future periods; however, non-GAAP financial measures are not meant to be considered in isolation or as a substitute for, or superior to, gross margin, operating income, operating margin, net income or EPS prepared in accordance with GAAP.

POLYCOM FINANCIAL PERFORMANCE COMMENTARY Revenue • Product revenues in 2017 grew 4.8% in 2017 relative to 2016, with particularly strong YoY growth in the second half of 2017. This is in large part due to growth in voice revenues, reflecting the Company’s high market share in both voice end points and voice conferencing markets as well as recent product launches including the refresh of the Trio voice conferencing product • Service revenue has been impacted by a steady decline in legacy maintenance revenues compared to growth from new products and managed services. Services revenue was down 5.3% in 2017 relative to 2017 • Revenue in Q1 2017 was above plan by ~$12 million due to one-time changes to commercial terms which impacted the timing of revenue, with stronger than expected SoundStation conference phone sales and higher Group Series sales in North America. Platform also performed above plan due to strong China sales. • Q1 2018 will see a normalization of revenue performance. Although financial statements have not yet been finalized, Q1 2018 revenue is expected to be approximately $271 million, consisting of Product revenues of $192 million and Services revenues of approximately $79 million. Polycom is expected to file financial statements for their fiscal Q1 2018 ended March 31 on May 30, 2018 Gross Margin • Gross margin in the product division improved from 52.3% in 2016 to 53.9% in 2017 • Gross margin in the services division improved from 62.2% in 2016 to 63.5% in 2017 • Continued gross margin improvements are the result of ongoing initiatives to shift headcount to lower cost geographies, eliminate headcount in certain areas of the business (MediaSuite) and logistics optimization • Q1 2017 Gross profit was ~$12.5 million above plan driven by stronger mix in video and lower discount claims. Reduced channel rebates in North America and EMEA and lower product unit costs also favorably impacted gross margin which is likely to normalize in Q1 2018 Operating Expenses & Non-GAAP Operating Income • Sales and Marketing expense as a percentage of revenue declined from 28.2% in 2016 to 23.7% in 2017. This decline was driven primarily by a reduction in program spend and optimization of marketing costs • Research and development expense as a percentage of revenue declined from 14.7% in 2016 to 11.9% in 2017. The reduction was driven primarily by consolidation and downsized R&D resources working on Platform focused programs • General and administrative expense dropped from 8.0% in 2016 to 6.0% in 2017, a dip driven by the elimination of public company costs, downsizing, and the subleasing of vacant office space • Q1 2017 operating expenses benefitted from lower than anticipated expenses primarily driven from delayed program spend in Engineering, higher attrition, slower hiring ramp, and lower overall IT and Facilities spend. • Q1 2018 Non-GAAP Operating Income is estimated to be $42 million vs.$45.8 million in Q1 2017 Adj. EBITDA • Adj. EBITDA in recent periods has grown due to prudent expense management initiatives. Primary costs for Polycom include costs of products/services, sales and marketing, research and development, and general and administrative. Cost of products/services has decreased in recent periods due in part to the favorable shift in product mix to voice end points. Sales and marketing, research and development, and general and administrative costs have declined in recent periods driven mainly by lower headcount-related costs including compensation and related benefits in addition to facilities and IT cost rationalization initiatives implemented by Siris to streamline the business • Q1 2018 Adj. EBITDA is estimated to be approxiately $51 million, up from their annual operating plan for the quarter of $43.8 million © Plantronics 2018. All Rights Reserved. 57
