I. Executive Summary

5

Executive Summary

International Paper (“IP”) believes its $30.60 all-cash offer for Temple-Inland (“TIN”) is highly compelling, representing a 46% premium to TIN’s share price on the announcement date of June 6, 2011

Analyst expectations for TIN have declined considerably since announcement, with consensus estimates for TIN’s 2011 and 2012 EBITDA having declined 9.3% and 6.0%, respectively

IP believes TIN’s per share value, not taking into account IP’s proposed transaction, is at best near its pre-announcement share price of $21.01

As a result of flat Q2 2011 performance, TIN’s H2 results must significantly outperform its H1 results in order to meet these reduced consensus estimates for FY 2011

IP believes its offer reflects TIN’s current prospects as a standalone company and compensates TIN’s shareholders for over 50% of the estimated synergies

TIN management has been unwilling to engage in meaningful discussions, only maintaining that IP’s offer grossly undervalues TIN

IP remains committed to this transaction and stands by its current offer

TIN’s Average EBITDA Multiple Has Been 6.1x

IP Views

Since 1/1/08, the “new” Temple-Inland has traded at an average forward EBITDA multiple of 6.1x

TIN’s 2011E EBITDA of $466 million and 2012E EBITDA of $601 million are well above 5-year historical average of $434 million In a cyclical industry, investors typically do not apply average multiples to above average EBITDA

Before the offer announcement, TIN was trading at 5.1x 2012E EBITDA and analyst price targets ranged from $25-$29 per share (with an average of $26.88, present value of $23.57)

Multiples Comparison

IP believes its offer is especially compelling when viewed relative to TIN’s average TEV / 1-Year Forward EBITDA multiple of 6.1x and the average peer TEV / 2012E EBITDA multiple of 5.5x 1 Applying TIN’s average TEV / 1-Year Forward EBITDA multiple (6.1x) to TIN’s average annual EBITDA over the last 5 years ($434mm) results in an implied price per share of approximately $17 Applying the consensus estimate for TIN’s 2012E EBITDA ($601mm) to the average current TEV / 2012E EBITDA multiple of comparable companies (5.5x) results in an implied price per share of approximately $22

Valuation Conclusion

IP believes its $30.60 all-cash offer for TIN is highly compelling IP’s proposal shares over 50% of synergy value with TIN shareholders At $30.60 per share, the offer represents a 46% premium, which IP believes is already very large for low-growth, established industries such as containerboard As a result of reductions in 2011 EBITDA estimates for TIN, IP has effectively increased its offer of $30.60 by 10% TIN’s Timber Tax Liability is real; IP considered TIN AMT tax attributes separately IP’s offer represents a high valuation multiple relative to trading and precedent transactions

Comparison of IP and TIN Timber Tax Liability Calculation

Apples to apples comparison of Timber Tax Liability views, IP vs TIN, is $385 million vs $184 million TIN deducts $250 million for utilization of AMT credits

IP has separately valued (outside of the Timber Tax Liability) all of TIN’s tax attributes and that value is reflected in IP’s proposal The $201 million difference is predicated on different calculation assumptions; IP stands by its assumptions absent additional information from TIN

IP is likely understating liabilities as its net debt does not include the $441 million of underfunded pension and postretirement obligations

Notes $ in millions

TIN View of Timber

Tax (Liability) / Asset (184)

Adjustments:

Earnings on net equity are used to offset net interest expense of the liability on an annual basis. As such, the NPV of the net equity should be included Net Equity Offset (147) • The value from the net equity will not be realized until the facility is unwound in November 2027

TIN did not PV the ~$243MM. Discounting at TIN’s 4.5% for 16 years = $96MM. The difference is $147mm

TIN put in a backstop facility in 2010

Backstop Costs (51)

TIN currently pays $5MM in backstop costs annually, which we assume will be renewed in the future. The NPV of this cost is $51MM, which TIN does not include in its analysis

Analysts Believe the Product Pricing Environment Has Become More Negative

“Expectations of the next price increase have again been pushed back… The number of contacts that now think there will be no price increase in 2011 jumped to 18% from 5% last month. Interesting, the vast majority was independent converters and overall, 33% of independents surveyed held this view. They pointed to an unfavorable supply/demand balance, an economic slowdown and some reports of price discounting.”

– Joshua Zaret, Longbow Research, 6/13/11

“Macro indicators have pointed to a potential slowing in the economy and containerboard markets are not quite as tight as we had thought they might be at this juncture. May industry data was a bit soft and expectations of a summer price increase have faded. The stocks, in the meantime, have been fading and are all well below highs from earlier this year with IP down 18%, PKG down 14%, and RKT down 20%. We are taking our EPS numbers down a bit as we push back our price hike expectation from August to October.”

– Mark Weintraub, The Buckingham Research Group, 6/21/11

“Our valuation for TIN would be roughly $28 using our pre-IP/TIN announcement forecast of increased containerboard pricing (it had been $80/ton over 2H11-2012; since the announcement we now assume no pricing until 1Q12) and some initial Box Plant Transformation Program II (BPT2) benefits (about $5-10/ton) in 2011-12. As such, IP’s point that its current cash offer of $30.60 includes value for future benefits to accrue to TIN shareowners has merit in our view.”

– George Staphos, Bank of America Merrill Lynch, 6/21/11

“May numbers raise the “degree of difficulty” on any prospective price hike. With cost pressures intensifying, H2 margins are apt to be under pressure… While there has been speculation that IP’s bid for TIN could table any price initiative, we’d keep the main focus on supply/demand. These numbers don’t help that case. Moreover, based on commentary at DB’s Industrials Conference, it doesn’t appear that Rock-Tenn will be making any supply cuts before late summer.”

– Mark Wilde, Deutsche Bank, 6/15/11

“Recent industry data have improved, and commentary around April sounds solid, supporting our view of a summer price increase. That said, we think this is now baked into Street models, so incremental upside would need to come from more extended above-average volume growth, tough in a slower macro environment.”

– Phil Gresh, J.P. Morgan, 4/20/11
