Introduction to Corvex • Value?based investing across the capital structure in situations with clearly identifiable catalysts • Active investing tocreate asymmetric risk/reward opportunities • 13D investments since inception include AboveNet (acquired by Zayo in March ‘12), Corrections Corporation of America (submitted private letter ruling to IRS for REIT conversion in July ‘12), and Ralcorp (Keith Meister joinedBoardin October ‘12) • Corvex owns common shares and share equivalents representing approximately 5% of ADT (13D filed today), making the investment ourlargest position since inception | 3 CORVEX MANAGEMENT LP

Company Overview • ADT is the market leader in home security monitoring in the U.S. and Canada, with approximately 6.5 million subscribers • 90% of ADT’s revenues are recurring monthly service fees ($38 ARPU),withannual attrition of13% • Holds25%marketshare,~6xthenextlargest competitor • $9.0B market cap and $11.2B TEV(1); ~$3.2B of revenue and ~$1.6B ofEBITDA (~49.2% margin(2))forthefiscalyearending 9/30/12E • EV / ‘13E EBITDA of 6.5x and ‘13E levered ‘steady?state’ free cash flowyieldof10%(basedon existing capital structure) (3) • 2007?2012E revenue and EBITDA CAGRs of ~9% and ~13%, respectively (including $2.0B Brinks acquisition) • Spin ?off from Tyco was completed on September 28 (1) Based on a closing price of $38.10 on October 23, 2012.

Investment Thesis • Unique franchise asset • Defensive, predictable business model • Strong financial profile with stable, consistent cash flows • Unappreciated secular growth tailwinds • The right asset for today’s economic and interest rate environment • Massive balance sheet optionality -Ability to increase leverage and improve capital allocation -Equity shrink story waiting to happen -Accelerate growth (organically or inorganically) -Attractive returns on invested capital Maintaining current capital structure is indefensible | 5 CORVEX MANAGEMENT LP

Why is ADT Mispriced? • Investor disappointment over capital structure post?spin • Unclear plans for capital allocation • Lack of true public comps • Market confusion over sustainability of low cash tax rate • Capital intensive but high ROIC growth • Disbelief of market penetration potential • Complicated accounting • Flow?back issues after spin?off • Sellside coverage issues We believe all of these issues are temporary / correctable | 6 CORVEX MANAGEMENT LP

Unique Franchise Asset • #1 market share in the highly fragmented home security industry • 25% market share and ~6x relative market share • Large and stably growing industry, with low penetration relative to other home services (~40% addressable market penetration) • Attractive returns on capital, with ~14?21% unlevered IRRs on new subscribers Charts per ADT Investor Day Presentation (9/18/12) . | 7 CORVEX MANAGEMENT LP

Defensive, Predictable Business Model • Services are valuable to customers: safety and security of family and property represents a non?discretionary expenditure • Recession resilient: total revenues grew 4% in 2008 and 3% in 2009 (organically); overall industry also grew in both of last recessions • Customers are generally middle and upper class homeowners with assets to protect Security Alarm Monitoring and Servicing Chart per Ascent Capital (Monitronics) presentation. Barnes Associates data, February 2012. CORVEX MANAGEMENT LP

Recurring, Contract ?Based Revenues • 90% of revenues are recurring monthly service fees • 3 year initial contract length and ~7?8 year average customer life • Upfront installation fees of several hundred dollars help screen for committed subscribers Annual Attrition 23.0% 2007 2008 2009 2010 2011 2012E ADT Verizon AT&T DirecTV DISH Cable (Industry Estimate) Source: Company filings, Wall Street Research.

The Right Asset for Today • ADT is the right asset for today’s economic and interest rate environment • Equity can be thought of as a stable stream of cash flows from the Company’s existing subscriber base, plus a differentiated platform for ongoing growth investment with attractive returnsoncapital • The value of ADT’s existing subscriber base has never been higher giventhecurrentultra?low interest rate environment -Furthermore, lowering Company’s cost of capital by increasing leverage creates immediate equityvalue • In addition, we believe ADT is currently under?earning with “Pulse” (significantly higher ARPU product) at less than 3% of its subscriber base compared to a take rate of 39% for new internally generated subslast quarter -Recovery in new household formation, which appears to be taking hold,shouldalsoliftoverallmarketgrowth | 11 CORVEX MANAGEMENT LP

Returns Summary • ADT represents an attractive risk?adjusted return investment with multiple waystowinandstrong downside protection • Our Base Case assumes: 6.0% and 7.0% recurring revenue growth in FY13 and FY14, respectively; ~200bps of margin expansion over FY13 and FY14; debt proceeds from step?up in leverage to 3.0x, leveraging ongoing EBITDA growth (? in EBITDA x3), and FCF after growthcapexusedtobuybackstock BASE UPSIDE DOWNSIDE CASE CASE CASE TARGET PRICE (ONE YEAR) $55.00 $63.00 $43.00 % Change 44.4% 65.4% 12.9% 2014E EBITDA $1,862 $1,862 $1,802 Net Debt / ‘13E EBITDA 3.0x 3.5x 1.3x Diluted Shares @ 9/30/13 156 136 235 % Change (33.6%) (42.0%) 0.0% TEV / ‘14E EBITDA 7.4x 7.8x 6.6x Levered Steady-State FCF Yield 10.1% 9.3% 9.3% Cash ‘14E P / E 12.4x 14.0x 13.7x GAAP ‘14E P / E 17.8x 20.1x 19.6x ‘14E RMR Multiple 49.9x 53.0x 44.3x CORVEX MANAGEMENT LP | 12

Valuation Summary • ADT’s business modelcreatesan annuitized streamofcashflows • We think about the stability of these cash flows similarly to REITs, utilities, MLPs,andbest?in?class consumer staples companies • Investors have gotten comfortable valuing REITs and other capital intensive industries onthebasisoffreecashflowafter maintenance capex, and then applying a multiple based on growth opportunities andreturnon investment -Steady?state free cash flow concept, which debt investors have become comfortable with,is essentially thesameasAFFO Levered Steady?State Free Cash Flow / AFFO Multiples ADT @ 3.0x ADT Current MLPs Staples REITs 9x 12x 15x 17x 22x Price @ Multiple: $61 $67 $83 | 13 CORVEX MANAGEMENT LP

Multiple Ways to Create Value • Financial outperformance -ARPU growth tailwind -Secular penetration opportunity -Margin expansion • Capital structure and capital allocation -Company’s existing debt now yields less than 3% (pre?tax) -Use balance sheet to accelerate growth organically or via M&A -3.0x net / EBITDA leverage level would enable ADT to immediately repurchase ~30% of the Company at attractive prices(1) (1)Capitalreturncouldtaketheformofshare repurchases or dividends depending onvarious considerations. | 15 CORVEX MANAGEMENT LP

Pulse and Home Automation • New interactive service offerings have the potential to transform home security product at a higher price point and expand the addressable market beyond traditional burglar alarms • ADT’s advanced “Pulse” offering consists of remote system arm / disarm, lighting and climate control, remote video monitoring and video clips, custom notifications and scheduled events, and other lifestyle features

Pulse Driving ARPU Growth Tailwind • Pulse has a 30%+ higher price point ($50+ monthly ARPU) than the Company’s existing subscriber base • Increased interactivity and higher customer satisfaction should also reduce churn, resulting in higher customer IRRs and cash flow • Less than 3% of ADT’s existing subscriber base has Pulse today; we believe this mix can rise to ~50% over time • Pulse take?rate is accelerating, reaching 39% of internal gross adds in the June quarter, compared to 35% in the prior quarter and 19% in the June quarter of last year • Pulse will begin to be offered through the dealer channel this fall, driving further adoption • ADT’s ARPU growth is accelerating, growing 2.8%, 3.5%, and 3.6% in the last 3 quarters, respectively | 17 CORVEX MANAGEMENT LP

Secular Penetration Opportunity • In addition to driving ARPU growth, home automation has the potential to increase residential penetration and drive market share gains for ADT • Pulse expands the value proposition of ADT’s services beyond the traditional security and life safety platform, increasing the size of the total addressable market -Pulse take?rates have grown more rapidly than expected, indicating strong customer interest in advanced service offerings • We estimate total addressable market penetration of only ~40% today; penetration of home automation nascent at only ~2% • New technologies will also make it more difficult for ‘mom & pops’ to compete in the historically fragmented home security industry, driving market share gains for technology and scale leaders like ADT | 18 CORVEX MANAGEMENT LP

Continued Margin Expansion EBITDA Margin % • We believe ADT’s margins will 50.0% continue to expand over time, 48.0% as they have done steadily over 46.0% the past 5 years, driving EBITDA 44.0% growth in excess of the top?line 42.0% • Management guidance of flat 40.0% ~50% EBITDA margins is 2007 2008 2009 2010 2011 2012E conservative, consistent with historical Tyco practice • Pulse results in increased upfront SAC, followed by increased ARPU flowing through at high incremental margins Chart (Cost to Serve) per ADT • Service margins in excess of 70% Investor Day Presentation (9/18/12). CORVEX MANAGEMENT LP | 19

Cost Structure Opportunity • After normalizing for estimated SAC expensed in SG&A, we estimate ADT’spre?SACSG&A represents over25%of revenues • Based on peers, we conclude that there are potentially material opportunities to improve ADT’s cost structure as a standalone public company, enhancing bothEBITDA margins andfreecashflow ($ in mm) ADT Breakdown Monitronics Breakdown Broadview Breakdown Protection One Breakdown 2009 2010 2011 2009 2010 2011 2007 2008 2009 2007 2008 2009 % Direct Sales / % Direct Dealer ~50% / ~50% 0% / 100% ~80% / ~20% ~90% / ~10% EBITDA $1,000 $1,191 $1,494 $153 $187 $217 $173 $205 $191 $107 $109 $123 Adjusted EBITDA (pre?SAC) 1,223 1,462 1,780 153 187 217 269 307 313 123 127 134 Adjusted EBITDA margin 54.4% 56.4% 57.2% 65.3% 68.8% 69.6% 55.5% 57.6% 55.4% 35.3% 34.1% 36.4% Adjustments: Expensed SAC within SG&A $223 $271 $286 NA NA NA $96 $101 $123 $15 $17 $11 Direct Comparison: SG&A 839 1,022 1,076 52 52 77 144 151 191 125 137 127 SG&A as % of Revenue 37.3% 39.4% 34.6% 22.4% 19.3% 24.6% 29.8% 28.3% 33.8% 36.0% 36.8% 34.6% Adjusted SG&A (pre?SAC) 616 751 790 NA NA NA 48 50 68 110 119 116 Adjusted SG&A as % of Revenue 27.4% 29.0% 25.4% 22.4% 19.3% 24.6% 10.0% 9.3% 12.1% 31.7% 32.1% 31.6% Advertising 76 113 152 NA NA NA 42 42 59 4 5 3 Advertising as % of Revenue 3.4% 4.4% 4.9% NA NA NA 8.6% 7.9% 10.4% 1.0% 1.3% 0.8% Memo: Revenue $2,247 $2,591 $3,110 $234 $272 $312 $484 $532 $565 $348 $372 $368 CORVEX MANAGEMENT LP Note: Protection Oneisonly~30% residential, andsmallbusiness customers typicallyhavehigherchurnandhighercosts. | 20

Financial Outperformance • Street has initially responded to management’s growth plan with skepticism • Analysts projecting ~3?5% revenue growth, compared to management’s goal of 5?7% • We believe management’s plan is achievable, and the ARPU tailwind from Pulse will lead to ADT exceeding revenue and profit estimates over time • Subscriber growth through home automation value proposition is a free call option on additional upside, with potential for both increased residential penetration and market share gains • Additional potential upside drivers include a recovery in new household formation (which appears to be happening), cost savings opportunities, and growth in small business channel | 21 CORVEX MANAGEMENT LP

Ability to Change Balance Sheet not Reflected in Current Valuation • ADT’s defensive business, predictable, contract ?based revenue stream, and high free cash flow conversion create opportunity for significant leveraging ofits balance sheet -ADT capital structure should have been an important consideration inTycospin?off rationale -Company’s existing 5?year debt literally trades at ~1.7% yield to maturity and the Company’s entire debt structure trades at a blended 2.96% yieldto maturity -There is a massive opportunity to lower ADT’s overall cost of capital by prudently increasing leverage that the Company is currently ignoring • Leverage for home security peers and cable companies is generally 2?5x EBITDA in the public markets (and, not surprisingly, often higherintheprivate markets) | 22 CORVEX MANAGEMENT LP

Optimize Capital Structure and Capital Allocation • We believe ADT should immediately increase leverage to 3.0x Net Debt / EBITDA and maintain a fixed leverage target of 3.0x going forward -3.0x level is conservative relative to home security peers, cable companies, andother alternative comps -Wouldenablethe Company to repurchase ~30%ofitsfloattoday(1) • Use debt proceeds to both return capital to shareholders and accelerate growth -Multiple accretive options exist -Changing cost of capital and buying back under?valued stock now creates significant long?termequityvalue • Use ongoing incremental debt proceeds (from leveraging EBITDA growth) and excess free cash flow to return capital to shareholders, andclearly communicate leverage targetandcapital allocation plan (1)Capitalreturncouldtaketheformofshare repurchases or dividends depending onvarious considerations. | 23 CORVEX MANAGEMENT LP

Bear Arguments • Limited FCF after growth capex • Cash tax shield going away after 2 years • Cable entry / threat | 42 CORVEX MANAGEMENT LP

Limited FCF After Growth Capex • A DCF is the best way to value ADT in our opinion • EBITDA –CapEx or FCF yield at a point in time is not a thoughtful cash flow valuation methodology -Not atypical for home security companies and other capital intensive businesses to have negative FCF -EBITDA –CapEx can be artificially inflated or deflated at any point in time by company’s level of discretionary growth capex • Equity investors should welcome growth investment by businesses with attractive returns on capital -Our analysis and field work supports the Company’s statement of ~14?21% unlevered customer IRRs -ADT should borrow at 3% and invest / re?invest in itself at ~14?21% returns as much as it can | 43 CORVEX MANAGEMENT LP

The Death of ADT’s Single?Digit Cash Tax Rate Has Been Greatly Exaggerated • The post–spin tax carryforwards along with cash tax planning opportunities will allow ADT to sustain a single?digit cash tax rate consistent with pre?spin cash tax rates (The ADT Corporation Form 10 Presentation, 4/10/12) • ADT will have significant deferred tax assets which results in the cash tax rate being significantly below the P&L rate -ADT expects to have $1.0 ?$1.2 billion of federal tax loss carry forwards at the time of the separation -In addition, ADT expects to have the ability to accelerate certain tax deductions that would allow us to minimize our cash tax rate for a period of time beyond the full utilization of the initial deferred tax assets (The ADT Corporation Investor Day Presentation, 9/18/12) | 44 CORVEX MANAGEMENT LP

Cash Taxes (cont’d) • While we will all learn more in November, our work has corroborated the existence of deferred tax assets (in addition to the inherited carry forward) which should enable ADT to preserve a low cashtaxratefor6+years • Additionally, the business should continue to generate an ongoing cash tax shield through continued subscriber growth and the upfront deduction of subscriber acquisition costs • A more appropriate capital structure will also lengthen the duration ofADT’s valuable cashtaxassets • No evidence of significant one?time “bonus depreciation” in deferred tax liabilities onADT’s balance sheet • Conspiracy theorists seem to not understand that companies are only able to make limited commentary during spin?off and while awaiting IRSrulings | 45 CORVEX MANAGEMENT LP

Cash Taxes (cont’d) • No other home security company is a significant cash tax payer • Importantly, we expect to be very efficient from a cash tax rate perspective. That’s going to be driven by two things. First, we expect that we’re going to inherit between $1 billion and $1.2 billion NOL at the time of the spin. In addition to that, we have the opportunity to accelerate certain deductions that will allow us to minimize that cash tax rate for a period of time beyond fully utilizing that initial NOL that we inherit… Overall, we expect our cash tax rate will be driven by federal AMC taxes, state taxes and Canadian income and withholding taxes resulting in an overall cash tax rate of between 6% and 8%. (Kathryn A. Mikells, 9/18/12) | 46 CORVEX MANAGEMENT LP

Cable Entry / Threat • We believe cable threat is manageable, which is not necessarily a contrarian view • Discussion of cable entering home security numerous times over the past 10?15 years, without results to date • Comcast is only cable company with a real home security product today (passes ~40% of homes in the U.S.) -Other cablecos behind Comcast; ‘science project’ stage for some • Home security companies have watched Comcast’s test markets and other test markets historically and not detected any impact • Home automation and advanced service offerings could change the opportunity for cable, but more likely to grow the overall market and threaten ‘mom & pops’ than negatively impact ADT | 47 CORVEX MANAGEMENT LP

Cable Entry / Threat (cont’d) • Cable industry would need to improve its image and devote resources to effectively compete inhome security -Muchmore complicated salesand marketing effort -Home security involves thousands of dollars of installed equipment, requiring more skilled technicians (and limiting synergies with existing truckrolls) -Need to overcome real and perceived poor customer satisfaction andlousy customer service -Cable not historically strong at selling anything other than triple play -When cable began providing landline telephony in the 1990s (a commodity product), achieved only~7?8%shareafter5years • Home security endmarketisnot material tolargecable companies -Mainareaofgrowth outside ofcoretripleplayisSMB | 48 CORVEX MANAGEMENT LP

Cable’s Relevance as Comp Group Overstated • Pay?TV is saturated / fully?penetrated industry • High speed internet still growing, but blended cable revenue growth still lower than home security by ~30?40% • Several well capitalized competitors trying to steal existing subscribers in any given market • Business model based on distributing another company’s content -Industry facing declining margins in video product due to rising content costs • Poor customer satisfaction (negative net promoter scores) • Requires centralized network maintenance capex • FCF benefitting from hiatus in growth capex after industry ?wide rollout of DOCSIS 3.0 | 49 CORVEX MANAGEMENT LP
