To:	  	All Mitel employees	
From:	  	Message from Rich McBee <sent by Jordan Rudow/Denise Hogberg>	
Send:	  	06:15 AM ET – announcement day <gated by publication of the press release>	
Subject:	  	Mitel announces agreement to acquire Polycom	
Moments ago, we issued a press release <<link>> announcing that we have entered into a definitive agreement to acquire Polycom, a global leader in conference and video collaboration technology. I wanted to be the first to share this news with you, our employees in every corner of the world, whose efforts have put us in the strong position that enabled today’s announcement.
I’ve talked frequently about the fact that we are in an unprecedented period of technology, industry and market convergence. I’ve also talked openly about Mitel’s intention and strategy to lead consolidation. This proposed acquisition of Polycom, which we anticipate completing in the third quarter, is the next step on that journey.
A new company with the vision, technology, and talent to provide seamless communications and collaboration
Our vision is simple – to provide customers with seamless communications and collaboration. Mitel is globally recognized as a leader in voice communications. Polycom is one of the world’s most respected brands in conferencing and video collaboration. Combining our two companies will create a new global leader and the only company across enterprise, cloud and mobile with a complete solution – voice and video, communications and collaboration – making us uniquely able to deliver a rich, complete offering to our customers and a truly seamless experience across all environments. In addition, with a global footprint and complete portfolio, we gain significant expansion opportunities to cross-sell into our respective customer bases as Mitel pulls Polycom into the mid-market, and Polycom pulls Mitel into the enterprise market and substantially expands our presence in APAC.
A new company with market leadership and global scale
Once the proposed transaction is completed, the combined company will be able to offer customers a complete and unique integrated technology experience supported by an impressive ecosystem of technology partners. Customers and partners of the combined company will benefit from access to a broad range of technology solutions backed by an impressive array of market-leading positions:
 
 	•	 	#1 in business cloud communications	
 
 	•	 	#1 in IP/PBX extensions in Europe	
 
 	•	 	#1 in conference phones	
 
 	•	 	#1 in open SIP sets	
 
 	•	 	#2 in video conferencing	

 	•	 	#2 in installed audio	
 
 	•	 	An installed customer base in more than 82% of Fortune 500 companies	
 
 	•	 	Deep product integration with Microsoft solutions	
 
 	•	 	Mobile deployments in 47 of the world’s top 50 economies	
 
 	•	 	More than 2,100 patents granted and more than 500 patents pending combined	
As a combined company, with a global footprint across five continents and approximately 7,700 employees worldwide, customers will have greater access to industry solutions and employee expertise than ever before.
A new company with an enhanced platform for profitable growth
As we continue to transform Mitel with this acquisition, we are once again positioning to double the size of our company. Once the proposed transaction is completed, we believe that the combined company will have a significantly stronger financial platform with the technology, scale and operating leverage needed to strategically expand in an actively evolving market, including:
 
 	•	 	Pro Forma $2.5 billion in diversified annual sales	
 
 	•	 	Pro Forma annual EBITDA of approximately $350 million	
 
 	•	 	Significant reduction in net debt leverage for Mitel from 3.8x to 2.1x	
 
 	•	 	Strong free cash flow generation	
An exciting day but business as usual
There is no doubt that bringing together Polycom’s world-leading conferencing and video collaboration and Mitel’s communications leadership and expertise can create a formidable market and technology leader. Mitel acquisition and integration activities have been an accelerator to our overall business performance and I know we are all eager to get started, but it is important to remember that until the transaction is complete, it is business as usual. The acquisition is subject to shareholder and regulatory approvals and other customary closing conditions.
Both Mitel and Polycom must continue to operate independently of each other and avoid acting as one company. Outside of a small team of senior leaders from both organizations, who will work with the Integration Management Office (IMO) to consider how to best combine our companies, all Mitel employees must refrain from exchanging information or connecting to their counterparts at Polycom, including via social media. Do not post, comment, or retweet about this proposed acquisition AT ALL. Your management team has been briefed on these rules; reach out to your manager if you have any questions or if you are contacted by anyone outside of Mitel with questions about the proposed acquisition. I also ask all employees to review the FAQ document <<link>.

In the meantime, I cannot stress enough how important it is that you stay focused on doing your job, meeting your objectives and driving our current business. We know how to do this well. Through a long history of acquisitions, Mitel employees are well versed in how to focus on the job at hand, with no disruption to the business or to our customers, as we move through transaction close and toward the integration process.
All-employee Town Hall today
I know employees will have many questions. As always, I am committed to communicating as openly and transparently as possible and I will be hosting a special Town Hall meeting day. Details are provided below. We have also established a special internal employee email address – whatisthedeal@mitel.com  – so that we can address your questions on an ongoing basis.
I look forward to discussing and celebrating this major Mitel milestone later today.

Customers

 	•	 	drive productivity across their organizations	
 
 	•	 	reduce the number of vendors and equipment they need to consider and string together, simplifying their purchasing and vendor management strategies	
 
 	•	 	further anchor the relationships they can build with their customers and business partners	
 
 	•	 	Upon closing of this proposed transaction, Mitel will be unique in its ability to make communications and collaboration seamless across any environment, whether mobile, cloud, or premises, and for any size of customer, from the smallest of businesses to the largest of service providers. We look forward to helping current and future customers overcome the challenges they face in trying to integrate disparate tools and resources.	
Competitors
 
 	•	 	We believe that our traditional enterprise competitors will be put on the defensive. We believe that they will have to explain how a string of pearls approach will be better than a cohesive, purpose-built holistic approach to communications and collaboration.	
 
 	•	 	For cloud competitors , we believe a Mitel-Polycom transaction will require them to explain why anything less than HD quality voice and video solutions is acceptable.

 	•	 	Large enterprise competitors will, we believe, have to answer how they plan to seamlessly leverage voice and video collaboration across not only the premises environment but also the cloud and mobile environments.	
 
 	•	 	Service provider competitors will, we believe, have to explain how they can compete with market-leading video technology that is now being coupled with market-leading real-time voice, cloud and 4G LTE mobile technologies.	
 
 	•	 	Traditional video competitors will, we believe, have to outline how they serve customers beyond the conference room, as those customers increasingly move to mobile cloud environments.	
 
17.	Is there opportunity for sales growth via new solutions or cross-selling?	
 
 	•	 	Absolutely. Upon closing of the proposed transaction, there will be significant opportunity to cross sell into our respective customer bases.	
 
 	•	 	Mitel will gain access to Polycom’s global installed base of 400,000 customers in many of the world’s largest companies, including 82% of the Fortune 500. Similarly, Polycom will gain access to Mitel’s installed base of 60 million end user customers and entrenched footprint with mobile service providers around the world.	
 
 	•	 	Ultimately, all customers would have a richer, more complete portfolio from which to choose.	
 
18.	Are the companies concerned that Polycom customers will stop purchasing Polycom products as a result of this proposed acquisition?	
 
 	•	 	That was an obvious consideration we identified when we went through the due diligence process. As part of that process, we conducted independent third-party research with the customer community and with many of their customers. We were pleasantly surprised by the response; the concerns of both customers and their customers’ centered on Polycom’s strong brand recognition and renowned product quality. This deal is structured to help protect both of those assets – retain a valued brand and do nothing to disrupt the supply chain for customers.	
 
19.	How will the combined company manage the acquisition?	
 
 	•	 	From now until the transaction is completed, it is business as usual. Both companies continue to operate independently of each other. All employees of both companies are subject to strict anti-trust regulations and competition laws.	
 
 	•	 	During this period, a small joint integration team, led by Mitel’s Integration Management Office (IMO) and including a mix of senior leaders from both companies, will take the time to do the careful and thoughtful analysis required to review the functions of each business and lay the path to a seamless integration.	
 
 	•	 	Mitel has a long history of successfully integrating companies, and employs a highly disciplined methodology.	
 
 	•	 	Mitel will bring its extensive experience in integration to bear on this acquisition, including:	
 
 	•	 	understanding that there is no cookie-cutter formula; each acquisition is unique	
 
 	•	 	moving quickly but carefully, minimizing any disruption to ongoing business	
 
 	•	 	communicating early and often with staff, partners, and customers	

 
Mitel Proprietary Information	  	•    For Internal Use	  	 	7	  	

 
 	•	 	assessing company culture and ensuring cultural considerations inform the integration plan	
 
20.	How many employees do you expect the combined company to have? How many sites around the world?	
 
 	•	 	In 2014, when Mitel acquired Aastra, the company doubled in size overnight – going from $600 million in revenue to $1.2 billion – and significantly expanded its workforce and global presence.	
 
 	•	 	Mitel will double again with the acquisition of Polycom, growing to approximately $2.5 billion in revenue, and with:	
 
 	•	 	approx. 7,700 employees across North America, Europe and Asia	
 
 	•	 	more than 170 offices on five continents, including a much expanded presence in APAC	
 
21.	How much of the benefits of the transaction would come from cost savings?	
As we indicated in the press release announcing the transaction, we anticipate total aggregate synergies from all sources to be approx. $160 million by 2018.
 
22.	Does the company plan more acquisitions as a result of this announcement?	
The company’s M&A funnel is always full. Mitel is continuously evaluating potential opportunities that would enable the company to lead in a rapidly consolidating marketplace, grow the business, and help customers solve their communications problems.
 
23.	What happens to Polycom leadership?	
 
 	•	 	Rich McBee will become the CEO of the combined company. Mitel’s CFO, Steve Spooner, will continue in that role. For the balance of management, we are not in a position to make any decisions. However, we can say that the combined company will bring together the best of both Mitel and Polycom technology, products, processes, and teams.	
 
 	•	 	Further announcements related to management appointments for the combined organization will be made after that transaction is closed.	
 
 	•	 	It is too early in the process to discuss what the organization would look like post close. When we have more information to share, we will.	
 
24.	This must mean layoffs as you think of product and functional overlaps. Where will the impacts be greatest?	
 
 	•	 	As in all acquisitions of this magnitude, there will be duplication of some functions. While there will be economies of scale arising from combining the two companies, it is expected that the bulk of employees will be unaffected.	
 
 	•	 	It is too early in the process to discuss specifics about operations of the combined company, including staff and office locations. No specific decisions have been made at this time and will not	

 
Mitel Proprietary Information	  	•    For Internal Use	  	 	8	  	

 
 	be made until the integration process gets underway following close of the transaction, expected in Q3 this year.	
 
25.	How much of an advantage does this give you to better compete with Cisco, Avaya, and new entrants like Slack in the enterprise?	
As a result of the proposed acquisition with Polycom, the combined company will have significantly greater scale and presence in the marketplace, as well as become the [only] company able to bring a complete communications and collaboration portfolio – voice and video, communications and collaboration – across the enterprise, cloud and mobile environments. With the industry’s broadest portfolio, and leadership across that portfolio, we believe that the combined company will be considered by more and more customers, and invited to submit more RFPs.
 
26.	Polycom recently reported challenges with its business. Why is it that Mitel can overcome these and Polycom could not?	
 
 	•	 	Mitel cannot speak on behalf of Polycom’s business.	
 
 	•	 	What we can say is that Mitel has a very clear vision for the combined company, and a strategy to leverage the portfolio of products. The two organizations complement each other well. For example, Polycom’s strong presence and critical mass in Asia-Pacific will give the combined company an entrenched position in that region; while Mitel’s leadership in cloud and mobile will enable us to rapidly deliver integrated video capabilities to customer in those segments.	
 
27.	Polycom has a large service provider network. How will Mitel engage/retain this important customer base?	
 
 	•	 	As part of our due diligence, we conducted independent third-party research with the service provider community and with many of their customers. We were pleasantly surprised by the response; both service providers’ and end customers’ concerns centered on Polycom’s strong brand recognition and renowned product quality. This deal is structured to help protect both of those assets – retain a valued brand and do nothing to disrupt the supply chain for customers.	
 
 	•	 	Following the close of the proposed transaction, we will continue to support those premium products and serve that customer base with a robust product portfolio.	
 
28.	You’ve been talking about your vision – the Mobile Enterprise. Does this mean you now can help companies get there? Could you not before? So, the Polycom technology was the missing link?	
Our Mobile Enterprise strategy is all about taking the different ways people communicate and collaborate, and making it seamless – across devices, technologies, environments. Adding

 
Mitel Proprietary Information	  	•    For Internal Use	  	 	9	  	

 
conferencing and video collaboration will complete that picture and will bring a richer, more integrated seamless experience.
 
29.	What happens to your relationship with Vidyo, who used to provide your video capabilities?	
 
 	•	 	It is business as usual. There are no current plans to change our portfolio or to the solutions we offer customers and we plan to continue to sell and support Vidyo solutions.	
 
 	•	 	We continue to work closely with Vidyo on joint development projects to ensure we can continue to offer customers a complete Mitel UC solution integrating Vidyo capabilities.	
 
30.	How does this agreement truly help you or Polycom in the regions such as EMEA, APAC, or other emerging economies? Are there any notable regional benefits for either company where there were previous customer weaknesses?	
The two organizations complement each other well. For example, we believe Polycom’s strong presence and critical mass in Asia-Pacific will give the combined company an entrenched position in that region; while we believe Mitel’s leadership in cloud and mobile will enable us to rapidly deliver integrated video capabilities to customer in those segments.

(CUSTOMER ADDRESS)
(DATE)
RE: Mitel’s Intent to Purchase Polycom
Dear (Customer/Prospect Name),
As you may have read or heard, Mitel has entered into a definitive agreement to acquire Polycom, a global leader in conference and video collaboration technology. To help communicate the importance of this announcement, I wanted to reach out to you personally and offer my thanks in enabling Mitel to make this transaction possible. Upon deal close, the combination of Mitel and Polycom will forge a company with both the vision and technology to make communications and collaboration seamless. The acquisition is subject to shareholder and regulatory approvals and other customary closing conditions.
Making Communications and Collaboration Seamless
Over the past few years, Mitel has been vocal about our intent to capitalize on the changing technology environment with an ambitious and proactive strategy to bring together disparate technologies by leading industry consolidation. The proposed acquisition of Polycom, which we anticipate completing in the third quarter, is the next step on that journey. You have come to trust Mitel as a global leader in voice communications. Polycom is one of the world’s most respected brands in conference and video collaboration. Combining the two companies will create the only provider across the enterprise, cloud and mobile environments with all the technology pieces – voice and video, communications and collaboration – to deliver a rich, complete offering to our customers and a truly seamless experience. This transaction also establishes a new company operating model with the strategic scope and global scale to meet customer needs across all segments – wherever they are and whatever they may be.
A Comprehensive Footprint, Expansive Real-Time Communications Capabilities
Once the proposed transaction is completed, I will be able to share more specifics on how we plan to offer customers a complete and unique integrated technology experience. As a combined company, with a comprehensive footprint across five continents and approximately 7,700 employees, Mitel customers worldwide will have greater access to industry leading solutions, including:
 
 	•	 	#1 in business cloud communications	
 
 	•	 	#1 in IP/PBX extensions in Europe	
 
 	•	 	#1 in conference phones	
 
 	•	 	#1 in Open SIP sets	
 
 	•	 	#2 in video conferencing	
 
 	•	 	#2 in installed audio	
 
 	•	 	Installed customer base in more than 82% of Fortune 500 companies	
 
 	•	 	Deep product integration with Microsoft solutions	
 
 	•	 	Mobility deployments in 47 of the world’s top 50 economies	

A Firm Financial Foundation to Rely On
The new company will aim to provide an enhanced platform for Mitel’s operational growth as well. With this acquisition, Mitel will be positioned to double the size of our company. Once the proposed transaction is completed, we believe that the combined company will have a significantly larger financial platform with the scope, scale and operating leverage needed to strategically expand in an actively evolving market, including:
 
 	•	 	Pro-forma $2.5 billion in diversified annual sales (as of CY2015)	
 
 	•	 	Pro-forma annual EBITDA approximately $350 million (as of CY2015)	
 
 	•	 	Significant reduction in net debt leverage for Mitel from 3.8x to 2.1x	
 
 	•	 	Strong free cash flow generation	
Business as Usual
As of today, it is business as usual. Until the transaction closes, both Mitel and Polycom must continue to operate independently of each other and avoid acting as one company. During this time, you should continue to work with Mitel just as you do today, knowing that we are committed to serving your business and the users you support.
Thank you for the chance to earn your business each day and I look forward to speaking soon.
Sincerely,

Non-GAAP Financial Measures
In an effort to provide investors with additional information regarding the company’s results as determined by generally accepted accounting principles (GAAP), the company also discusses, in its press releases and presentation materials, non-GAAP information which management believes provides useful information to investors, including Adjusted EBITDA, non-GAAP net

income, non-GAAP operating expenses, non-GAAP Revenues and non-GAAP Gross Margin. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similar measures presented by other companies. We use these non-GAAP financial measures to assist management and investors in understanding our past financial performance and prospects for the future, including changes in our operating results, trends and marketplace performance, exclusive of unusual events or factors which do not directly affect what we consider to be our core operating performance. Non-GAAP measures are among the primary indicators management uses as a basis for our planning and forecasting of future periods. Investors are cautioned that non-GAAP financial measures should not be relied upon as a substitute for financial measures prepared in accordance with generally accepted accounting principles. Mitel provides a reconciliation between GAAP and non-GAAP financial information in our quarterly results announcements and in the supplemental slides used in conjunction with the company’s quarterly calls. This information is available on our website at www.mitel.com under the “Investor Relations” section http://investor.mitel.com/events.cfm.
