Vote NO on S.P. Richards Merger We urge ESND shareholders to vote NO on the proposed merger with S.P. Richards The S.P Richards (“SPR”) merger presents multiple risks that could destroy value for ESND shareholders: Substantial risk that antitrust approval is not received Secular industry headwinds for both ESND and SPR that will lead to continued underperformance Significant business integration hurdles and inability to achieve unrealistic synergy assumptions   We urge ESND’s Board to recommend Staples’ cash offer of $11.50 per share The Staples offer presents benefits to ESND shareholders: Offers greater certainty of closing due to less antitrust risk Cash consideration eliminates risk of continued underperformance Offer is not contingent on financing We believe Staples’ proposal represents a superior value to ESND shareholders

Key Risks the SPR / ESND Merger Creates for ESND Shareholders This presentation addresses a number of key risks of the proposed SPR merger that ESND shareholders should be concerned about: Risk #1: SPR Merger Has Significant Risk of Not Closing Due to Antitrust Issues Risk #2: ESND Shares Are Currently Inflated Due to Speculation About Staples’ Proposal Risk #3: The SPR Merger Requires Faith in Unrealistic Assumptions About the Go-Forward Company; Staples’ All-Cash Offer Provides Certainty of Value

Risk #1 SPR Merger Has Significant Risk of Not Closing Due to Antitrust Issues

ESND / SPR Unlikely to Obtain Antitrust Clearance ESND / SPR is a “merger to monopoly” Challenges levied by the FTC will not be remedied by synergy arguments ESND / SPR will be subject to a very long review process Staples’ proposal offers the clearest path to completion Staples’ proposal also offers a $20 million termination fee, which is at the higher end of precedents and payable to ESND if the transaction with Staples is terminated due to failure to receive antitrust clearance

ESND’s Stock Price Would Plunge if Shareholders Approve the SPR Deal and it is Then Blocked… 10 days prior to announcing the SPR deal, ESND hit its YTD low closing price of $7.44(1) ___________________________ Represents closing price on 4/2/2018. As of the unaffected share price of $8.47 on 4/11/2018.

ESND (77%) S&P 500 +66% ESND shares fell 77% in the 5 years leading up to the SPR merger announcement Declining industry trends will continue to pressure ESND regardless of whether the SPR merger is completed Indexed Stock Performance

…With Potential Downside to ~$4 per Share Based on Recent Performance If the SPR deal is blocked and ESND trades at its pre-announcement EV/EBITDA multiple of 6.9x, the implied price would be $4.22 ___________________________ Represents closing price 1 day prior to announcement of SPR transaction on 4/11/2018.

Risk #2 ESND Shares Are Currently Inflated Due to Speculation About Staples’ Proposal

Investors Valued Pro Forma Combination at Below $10 per Share ESND’s Current Trading Levels Are Based on Takeover Speculation ESND never traded above $10 post announcement of transaction and pre-Staples investment 4/12/18 Announcement of S.P. Richards Deal 4/25/18 Reported disappointing Q1 EPS ($0.19) worse than consensus 4/26/18 Staples / Sycamore begin building stake in ESND 5/16/18 Staples / Sycamore files 13D with $11.50 per share offer Staples Current Proposal: $11.50 ___________________________ Source: Capital IQ.

ESND’s Stock Price is Inflated by Staples’ Actions Over 81% of the gains in ESND stock price can be attributed to (1) Staples’ / Sycamore’s purchases of ESND shares and (2) the public announcement of Staples’ acquisition interest ___________________________ Source: Company Filings, S&P Capital IQ. If ESND shareholders approve the SPR merger and Staples withdraws its offer and sells its shares, ESND shares could lose significant value Staples’ / Sycamore’s purchases comprised 36% of trading volume during this period Higher trading levels post 13D filing despite decline in Q2 financial performance versus prior year and no improvement in business trends or SPR transaction terms. Current trading price based on takeover speculation and unrealistic price expectations

Risk #3 The SPR Merger Requires Faith in Unrealistic Assumptions About the Go-Forward Company… …Staples’ All-Cash Offer Provides Certainty of Value

ESND Management’s Poor Track Record Meeting Guidance / Expectations ESND and SPR Both Face Long-Term Secular Industry Headwinds ~35% of the Target Pro Forma 2020 EBITDA is Comprised of Synergies / Cost Cutting The SPR Merger Offers Unjustifiable and Less Certain Value vs. Staples’ All-Cash Offer Key Considerations for ESND Shareholders 1 2 3 4

ESND’s Management Has Consistently Cited Secular Industry Decline to Explain Underperformance 2 “Looking ahead, we continue to face a challenging industry dynamic, which will impact our business in 2017… Over time, we expect to fundamentally improve the value we bring to the marketplace and the profitability of our business. While we are focusing on executing phase 1 in 2017, this is a multiyear effort. We also expect the challenging industry dynamic we operate in to persist…” FY2016 Earnings Call 2/28/2017 – Robert Aiken, Former President and CEO “…it’s clear that we face significant challenges and that we need to do more to improve our business. Our ongoing initiatives are progressing as planned. But as I stated on our Q2 call, there’s simply not enough to offset the industry headwinds that we’re experiencing.” Q3 FY2017 Earnings Call 10/26/2017 – Richard Phillips, President and CEO “Sales with independent resellers were up year-over-year, primarily due to lower margin sales of technology and cut-sheet paper… Countering these sales gains, secular declines continue to provide headwinds in this channel.” Q1 FY2018 Earnings Call 4/26/2018 – Janet Zelenka, CFO FY2016 FY2017 FY2018 FY2019 Will the script be any different in 2019 and beyond?
