Executive Summary

Executive Summary Acacia is a leading patent licensing and enforcement company operating in an industry that is facing dramatically impaired market conditions . Legislation and court decisions have had a significant negative effect on the traditional patent licensing industry . Prospects and stock prices of all patent licensing and enforcement companies have declined significantly over the past few years . Patent licensing companies cannot simply exit the patent business (or distribute assets) due to ongoing litigation and partnerships with patent owners Acacia and its Board are utilizing their technology expertise, investment experience, tax assets and cash to transform the business, increase profitability, and preserve and increase stockholder value Acacia has aggressively pursued its new business strategy, including changes to management, the Board and compensation practices . Substantially streamlined the patent enforcement business, settling litigation and cutting headcount and operating costs . Significant management and Board changes have been made to ensure the right skills and expertise are available to help accelerate our new strategic plan; Compensation programs redesigned to better align pay with performance . Generated $280 million in revenue since 2016 Acacia has the right Board to execute the transition to the new business strategy . Acacia’s Director nominees are both significant investors, having invested more than $7 million in Acacia shares . The Board has recruited four new members since 2016 with needed skill sets, including technology investing and audit expertise Sidus/BLR are short-term focused and will likely seek to distribute the company’s cash or liquidate the business, which is neither in stockholders’ best long-term interests nor feasible . Ongoing litigation prevents the company from liquidating or distributing a significant portion of its cash . Sidus/BLR’s nominees have no current experience in the patent business or with investing in private technology companies . Sidus/BLR’s nominees own no stock . To minimize business distraction, we offered to add Mr. Tobia and one additional mutually agreed upon director onto the Board; Sidus/BLR rejected the offer and have insisted that both of their nominees join the Board 6

Legislative and Legal Changes Have Significantly Impacted the Industry “We’ve gone full circle from a very pro-licensing environment to an anti-licensing environment.” (David Pridham, CEO Dominion Harbor Group, in Bloomberg, 2016)  A new federal law substantially impairs the ability of “Non-practicing entity (NPE) litigation filings in non-practicing entities to enforce patents 2017 continued an erratic downward slide from their peak in 2011” (RPX, 2018)  The new Patent Trial and Appeal Board (PTAB) makes invalidating patents easier for defendants “It has become increasingly difficult for PIPCOs  Various legal opinions made patent prosecution to successfully enforce their patents, harder and challenges to patents easier causing many PIPCO valuations to plummet.” (Intellectual Asset Management, 2016) “The U.S. patent system has fallen to 12th place… [on the U.S. Chamber of Commerce Global Innovation Policy Center Index]. This comes after last year's surprising fall from first to 10th place, tied with Hungary.” (Licensing Executives Society (USA and Canada), Inc., 2018) Cases brought by patent licensing and enforcement companies have dropped by more than half since 2011* This has had a direct and significant effect on the profitability and value of these companies *Source RPX See Appendix for a list of new laws and legal precedents on patent enforcement 13

Part II: Acacia’s Decisive Response to a Changing Industry

The Acacia Board is Extremely Active and Engaged In 2016 and 2017, Acacia’s Board met numerous times through informal board meetings, committee calls and formal in-person board meetings to evaluate alternative paths for the business • The Board is committed to leveraging Acacia’s existing assets and expertise to create stockholder value while not jeopardizing the Company’s IP assets and revenue streams • In February 2018, the Board formalized its Strategic Review Committee, with Ted Walsh as Chairman, to identify, review and evaluate potential strategic opportunities • The Company has engaged a leading technology-focused investment bank to assist in executing its strategy and advise on potential transactions 18

Significant Restructuring of the Patent Licensing Business . In the face of industry headwinds, Acacia has transformed its patent licensing business . Acacia has found it increasingly difficult to find attractive patent portfolios for acquisition - It has become more difficult to value portfolios and to generate revenue from them - Acacia has reduced the number of patent portfolio acquisitions; few meet our strict investment criteria . Acacia “triaged” its patent litigation cases, successfully resolving and maximizing revenue from dozens of portfolios - Acacia is still pursuing numerous portfolio licensing programs with good prospects - Acacia is also a defendant or counter-claim defendant in a number of patent and related cases . Acacia has dramatically reduced its fixed operating expenses and reduced headcount - Significantly reduced operating expenses - 56% cut in fixed G&A run-rate expense - 70% reduction in headcount - 33% reduction in litigation expenses as a percentage of revenue - $108 million of cash from operations generated since 2016* Since 2016 Acacia has undertaken an extensive operational and organization restructuring to reduce costs and efficiently monetize existing IP assets * Does not include impact of March 31, 2018 current liabilities of $49 million 19

Acacia’s Diversification Strategy: Value-Added Technology Investments Technology Investing Has Been Part of Acacia’s DNA Since it Was Founded in 1993 . Acacia’s Key Strengths − Understanding complex technologies and their commercial applications − Evaluating and investing in technology patents − Securing and protecting technology IP from patent violations − Strong referral network of technology industry experts, entrepreneurs and C-suite executives − Deep financial and operational experience − Cash balance of $180 million − Significant tax assets: $172 million in NOLs and $52 million in foreign tax credits . The Opportunity in Partnering and Investing in Growth Technology Companies − Acacia’s referral network provides excellent and early access to technology investment opportunities − The Board’s and management's technology investing experience is supplemented by long-standing relationships with other technology investors, scientists, entrepreneurs and business leaders − The current fast pace of disruptive technological evolution is creating attractive investment opportunities for Acacia in AI, robotics, blockchain and many other dynamic areas of high-tech growth − Acacia has deep experience and expertise that makes us a value-added investor, including: identifying key technologies, securing intellectual property rights, valuing intellectual property, structuring financing, building high-performance organizations and cultivating a sophisticated investor base Acacia identifies many of its investment opportunities through the vast network of relationships the Company has built since 1993 as a leader in patent licensing and enforcement 20

Acacia's Targeted Technology Sector and Investment Criteria . Due to the radical pace of change in many high-tech sectors, Acacia believes that this is a very good time to be a value-added investor . Based on Acacia’s depth of expertise and the insights obtained from Acacia’s research and relationships, the Company is focusing its investing efforts in the following sectors: − Artificial Intelligence (AI) − Machine Learning − Machine Vision − Robotics − Blockchain Technologies . Within these sectors Acacia has developed strict criteria to apply in its investment decision process − Proprietary, proven technology; strong preference for patentable technologies or patent protection − Large addressable market for application of the technology − Identified and enthusiastic customer base − Outstanding management team with strong track record and capital invested − High quality co-investors − Institutional quality IT/MIS, compliance systems − Organizational ability to execute business plan − Ability of Acacia to add synergistic value for growth − An investment not otherwise available to Acacia stockholders 21

Acacia’s Corporate Governance . Carefully developed, independent, Board with skills and experience in critical areas − Appropriate balance between longer serving and newer members − Added investing and audit skills as part of transformation strategy − The Board worked methodically over 18 months to identify and vet two new board members before their appointment in 2018 . Board and management collectively own 11% of Acacia’s stock − Mr. Graziadio has purchased $5.4 million of Acacia stock in the open market − Mr. Walsh has purchased $1.6 million of Acacia stock in the open market . Our staggered Board has historically been necessary to protect stockholders because of the nature of our patent business − Acacia is regularly in litigation with much larger companies (e.g. Apple, Alcatel, Motorola) which could threaten to take over companies like Acacia as part of their litigation defense and general IP management strategy − Acacia’s Board is committed to eliminating the classified board structure in the future when it is determined to no longer be necessary to protect Acacia’s IP assets Acacia's Board emphasizes highly qualified, independent Board members, active refreshment of the Board, share ownership by Board and management, pay-for-performance, equity oriented/incentive based compensation, open dialogue with all stockholders and rigorous oversight by the Board 25

Acacia’s Compensation Philosophy . In 2015, we retained a compensation expert and engaged in a rigorous review of our compensation policies − Extensive stockholder engagement and outreach in 2015 and 2016, focused on compensation − In-person meetings and conference calls with key institutional stockholders − Engaged Pearl Meyer, a nationally recognized executive compensation advisory firm − Close alignment of executive compensation with corporate performance − Established specific performance milestones and targets − Designed new performance-based cash and equity executive compensation programs . Our entire compensation program was replaced, including the following changes: − We no longer use stock awards (which reward management even if the stock does not appreciate) − We often use options that only vest if Acacia’s stock price appreciates significantly Say on Pay Vote Results We received strong stockholder support for our 94% FOR 97% FOR compensation programs following these changes: 100% 80%  94% Vote FOR our compensation plan in 2016 60% 40%  97% Vote FOR our compensation plan in 2017 20% 0% 2016 2017 Acacia is committed to implementing a best-in-class executive compensation program tied to clear, high-value goals and stockholder value creation 26

Louis Graziadio’s Compensation . Mr. Graziadio has been our Executive Chairman since August 1, 2016 − In December 2015, our CEO and President resigned − The Board formed an Office of the Chairman, including Mr. Graziadio, to assist our interim CEO − On August 1, 2016, the Board disbanded the Office of the Chairman and appointed Mr. Graziadio Executive Chairman − Mr. Graziadio has been working nearly full-time since December 21, 2015, effectively acting as the Company’s chief executive without taking a salary . During the period that the Office of the Chairman was active, Mr. Graziadio devoted time and energy far in excess of what is customary for a director and received no direct compensation (other than standard Director fees) − Mr. Graziadio’s company, Second Southern, also incurred substantial direct costs for office space, admin services, IT, etc. − Consequently, in August 2016, the Board approved a $250,000 payment to reimburse Second Southern for expenses incurred from December 2015 through August 2016 . When appointed Executive Chairman, the Board approved the following compensation for Mr. Graziadio − No direct salary − 700,000 options as an onboarding grant that vests on the achievement of stock performance targets* − $250,000 per year in annual estimated expense reimbursement to Second Southern . $125,000 in 2016 for expenses from August through December .

The Importance of Maintaining A Healthy Cash Balance . As of March 31, 2018 Acacia held $180 million in cash, cash equivalents and short-term investments . Our business requires us to maintain a robust cash balance for several reasons, including: – To effectively advance Acacia’s patent licensing and enforcement business . The counterparties to our litigation are large, well-financed companies with substantially greater resources . To be regarded as a credible plaintiff, it is essential that we have sufficient capital to pursue litigation through trial and a possible appeal process – We are contractually obligated to enforce our licensed IP and therefore must pursue all reasonable licensing opportunities – Acacia is a defendant in several cases it must defend – Cash may be needed for unexpected adverse court judgments – For strategic investments into high-growth companies in potentially disruptive technology areas . Acacia announced a $20 million stock repurchase program on February 13, 2018 – Repurchase represents 10% of Acacia’s market capitalization – Stock purchases will be funded through cash on-hand and operational cash-flow Acacia has repurchased approximately $4 million worth of ACTG stock under the new $20 million buyback program 30

Summary of Results Under Acacia’s New Leadership . Strong results from patent licensing business − $280 million of revenue since 2016; $62 million generated in Q1 2018 − $108 million of cash from operations generated since 2016* .

Part III: Sidus/BLR's Misleading Accusations and Self-Serving Agenda

We Have Attempted to Maintain a Constructive Dialogue with Sidus/BLR . . Over the last six months there have been Acacia believes that its nominees are much numerous discussions in person, by phone and better suited to help create long-term via email stockholder value than Sidus/BLR’s nominees − Discussions have been frank and cordial − Patent prosecution and high-tech investing experience − Sidus/BLR have failed to provide any thoughtful ideas − Senior management and business operating experience about improving Acacia − Long-term view on value creation − Substantial personal share ownership . We have worked hard to avoid a contested election: . Sidus/BLR have been wrong about Veritone − Attempted to provide Sidus/BLR with a better − They wanted us to sell Veritone understanding of our business . Sidus referred to it as an “awful co. … could be a $0” − Offered an open invitation (four times) for Sidus/BLR . Mr. Press referred to it as a “Misbegotten enterprise” nominees to meet with Acacia’s Board with “hopeless prospects” − Explained Acacia’s compensation plan − Veritone stock has since increased by more than 50% − Offered to put Alfred Tobia from Sidus and a mutually to approximately $22 per share, creating $50M+ in agreed upon Director on the Board; offer declined value for Acacia Acacia’s Board and management team have spent a significant amount of time with Sidus/BLR Sidus/BLR have not identified any skills missing from Acacia’s Board and failed to articulate any strategy to create long-term, sustainable value We offered to add Alfred Tobia and another mutually agreed upon second director to the Board but the offer was rejected 33

Sidus/BLR’s Agenda is Wrong for Acacia During the many discussions with Sidus/BLR, the only proposal they have made is to execute a large share repurchase program funded by current cash and proceeds from the proposed sale of Veritone shares . A prudent cash balance is a critically important asset for Acacia’s patent licensing and enforcement business − Gives Acacia credibility in conducting litigation to enforce patents against well capitalized counterparties − Enables Acacia to fulfill our obligations with our patent partners and to robustly defend patent claims and counterclaims − Ensures Acacia can manage through any unexpected litigation related liabilities . Cash availability is also an essential asset for our partnership/investment business − Enables Acacia to exploit our key strengths and capitalize on technology partnerships and investing opportunities . Sidus/BLR’s agenda is short sighted and driven purely by a short-term, speculator’s mindset − Proposals reflect a desire to create a short-term rise in price and volume − Demonstrates a lack of understanding of the capital requirements that are distinct to Acacia − Acacia would be left with high financial risk and a fundamentally weaker patent and partnership businesses . Acacia has a $20 million share repurchase program already in place − Approximately 1.0 million shares, worth $3.7 million have been repurchased since May 3, 2018 Sidus/BLR’s proposal is fundamentally flawed and, in our opinion, will destroy long-term value 34

Acacia and its Board are utilizing their technology expertise, investment experience, tax assets and cash to transform the business, increase profitability, and preserve and increase stockholder value  Acacia is a leading patent licensing company operating in an industry that is facing dramatically impaired market conditions  Acacia has aggressively pursued its new business strategy, including changes to management, the Board and compensation  Acacia has the right Board to execute the transition to the new business strategy  Sidus/BLR are short-term focused and will likely seek to distribute the company’s cash or liquidate the business, which is neither in stockholders’ best long-term interests nor feasible  Sidus/BLR’s nominees have NO relevant knowledge about our business or industry and have NO plan for building long-term value In our opinion, the replacement of Acacia’s two engaged and shareholder-aligned Directors with Sidus/BLR’s nominees will destroy value 43
