Our Approach History Our Position in Agrium Work collaboratively with companies to address opportunities to unlock value for shareholders JANA’s approach “is co-operative rather than offensive.” – The Financial Times, December 10, 2009 JANA’s “victories have come largely by eschewing the aggressive public stances associates with fellow activists.” – The Wall Street Journal, October 7, 2012 Founded in April 2001 Research-intensive, value fund that manages ~$4.5bn in capital Since 2006, the average annualized return on stocks where JANA had outstanding 13D filings was 65%(1) We currently own ~$1.2bn of Agrium, ~7.5% of the company JANA is aligned with all shareholders, with the common goal to maximize shareholder value Meet JANA Partners I. Executive Summary Source: Company reports, Capital IQ. (1) Per 13D Monitor, January 31, 2013. 5

Our Solution Agrium can resolve historical problems and unlock significant value. The solution begins on Agrium’s board Agrium’s board has experience relevant to the company’s fertilizer manufacturing business (“Wholesale”), but is missing two key components that have caused Agrium to underperform its value creation potential Lack of distribution experience: Agrium’s agricultural distribution business (“Retail”), accounts for 30%+ of EBITDA, ~50% of total value and $4bn+ of acquisitions, yet Agrium has never had a single independent director with any significant ‘breaking bulk’ distribution experience Lack of shareholder orientation: Agrium’s board for years failed to pursue even the most obvious value-creation measures until pressured to do so, and continues to fight value-creating change today JANA has nominated 5 candidates who can enhance Agrium’s board by eliminating these deficiencies With the benefit of the new expertise and perspective of JANA’s nominees, Agrium can proactively address the remaining unresolved issues previously identified by JANA — the 5 C’s Retail costs Corporate costs Retail disclosure and performance targets Management incentives Capital return M&A / investment practices Retail working capital Valuation discount Operating issues Appropriate capitalization Governance missteps Appropriate experience I. Executive Summary 9

Partnered with Apollo to purchase UAP, oversaw IPO and sale to Agrium at 13x EBITDA, generating ~17x return from the Apollo LBO Past CFO of Graham Packaging, taking business from ownership under Blackstone to an IPO and eventual sale Hon.

Executive Summary 10

Favorable Reaction To JANA’s Engagement “JANA’s proposed board members possess solid retail distribution experience and could help unlock value.” – CIBC, 1/15/13 “[W]e see upside comfortably beyond $150 if the JANA slate wins, and initial downside to about $90 if the Agrium Board is re-elected.” – Credit Agricole / CLSA, 3/1/13 “After speaking with four of the five directors that JANA Partners is nominating for Agrium’s board, we came away impressed with the group’s clear industrial distribution experience and competence and their ability to articulate the kinds of operational improvements they would seek to implement at Agrium Retail.” – Barclays, 12/13/12 “While activist shareholder JANA Partners’ proposals have been met with stiff resistance from Agrium management, we believe that significant shareholder value creation may come from surfacing some of the issues raised by JANA” – Piper Jaffray, 12/2/12 “JANA is nominating a retail ‘dream team’ to Agrium’s board, which currently does not have one independent member with retail distribution experience” – Barron’s, 11/26/12 “JANA’s nominees to Agrium’s board appear highly credible to us.” – Bank of America, 1/29/13 I.

The Right Measurement End Date For Performance Comparisons Is June 1, 2012 JANA first engaged Agrium on ways to create value on May 31, 2012 Only a week later – on June 7 – Agrium reacted to JANA by increasing an already declared dividend by more than 100% Agrium’s increase of a dividend that had already been declared by the board only a few weeks earlier is such a rare event it was clearly in response to JANA’s engagement Reactions to JANA continued with a C$900 million share repurchase, a second increase of the dividend (by an additional 100%) and the introduction of significantly more new disclosure for Retail JANA began a dialog with analysts in late May / June Agrium’s sell-side analysts recognize that JANA’s impact on Agrium’s share price began in June “Investors have benefited from JANA’s actions as it sheds increasing light on the value of [Retail]. AGU shares have risen ~33% since mid-June, when JANA’s involvement in the stock became well known” – Susquehanna (10/23/12) Agrium also acknowledges JANA’s campaign and its impact since late May “JANA has been running its campaign for over eight months now.” – Agrium Board Chair, Victor Zaleschuk (2/20/13) “JANA has been trying for over nine months to obtain support” – Agrium Board Chair, Victor Zaleschuk (3/7/13) II.

Agrium’s Highly Engineered Measurement Period Disingenuous Start Date: 11/8/05 Disingenuously justified by pointing to Royster-Clark acquisition Agrium claims its $0.4bn Royster-Clark acquisition was the beginning of its Retail strategy, but it is dwarfed by Agrium’s truly transformative Retail acquisition – UAP, for $2.7bn in 2008 – which it funded in part with new equity Agrium misrepresents its Royster-Clark acquisition date. Agrium launched a hostile tender on 11/8/05, but holders did not tender until February 2006 (after Agrium extended the tender 5 times and raised the price twice, by ~20%) By opportunistically anchoring to 11/8/05, Agrium tries to take credit for the rebound in its share price following the temporary ‘shock’ in natural gas prices after Hurricane Katrina Nitrogen producers impacted as gas prices hit record highs Both Agrium and CF shares were impacted and recovered by February 1: CF up 24% and AGU up 21% from 11/8/05 Disingenuous End Date: 2/13/13 Includes more than 8 months of benefits from JANA’s engagement and its positive impact on Agrium’s stock End date within ~2% of Agrium’s all-time high and not updated for subsequent 8% share price decline before proxy was filed Agrium uses a highly engineered measurement period to claim strong absolute returns.

Retail’s Footprint Is A Prime Example Of Poor Cost Management(1) As described in Agrium’s 2007 Annual Report (page 22) and by a branch manager in this Agrium video: http://www.agrium.com/stories/1834.jsp (at 5:58). (2) Farm center and satellite locations. See page 51 for more detailed description of footprint analysis. Agrium’s Retail footprint is highly duplicative, violating the company’s own stated guidelines for branch effectiveness. Overlap: 25 Mile Radius Overlap with another location within radius No overlap within radius Farm Centers Only Farm Centers & Satellites Farm Centers & Satellites Overlap: 20 Mile Radius Memo: ~24 driving miles Memo: ~30 driving miles Farm Centers Only Agrium’s Retail distribution business is not a ‘walk-in’ traditional retailer, but is a remote order business where customers have a salesperson as their primary point of contact and rarely visit a Retail location Retail locations effectively serve as distribution centers Agrium has for years publicly stated that a Retail location typically services customers within ~25-40 miles(1), and cited a 50 mile radius for the US corn belt at its 2012 Investor Day However, Agrium’s 700+ continental US locations(2) show significant overlap at distances well within the functional radius that Agrium has cited III.

Retail Footprint: Overlap Within A 20 Mile Radius (~24 Driving Miles) Overlap within 20 miles of another location No overlap within 20 miles Note: Analysis based on Retail locations in continental U.S. listed on Agrium’s website (http://www.cpsagu.com/map/Default.aspx) as of Jan 17, 2013. Locations include only farm centers & satellites and for conservatism exclude regional & divisional offices, distribution centers, terminals, and plants which otherwise would have further increased the number of overlapping locations.

Agrium has no credible explanation for its highly duplicative footprint. Farmers select retailers based on their sales relationship, product cost and service / fill rate, not proximity to a farm center location. Customers order over the phone / through sales representatives, not at the farm center Farmers care about proximity to farm center and will switch suppliers if duplicative locations are consolidated Q: What are your key reasons for selecting your ag retailer?(1) Results of survey conducted by a leading independent global consulting firm. Results from a representative population of more than 100 U.S. farmers across geographic regions. “High Touch” and “Low Touch” customers can not receive delivery from / be serviced from the same physical farm center location “High Touch” vs. “Low Touch” is a customer / salesforce issue, not a farm center location issue Customer is agnostic, as the farmer does not go to a farm center for product – Agrium Retail delivers product directly to the farm Salesforce sells at the farm and is indifferent regarding back end logistics network as long as cost / service level is maintained Agrium Explanation Facts Overlapping Locations Optimized Location High Touch Low Touch All Touch Low Touch Sales High Touch Sales Farm Center Agrium Can Not Defend Its Highly Duplicative Footprint Not a key decision factor III.

Agrium’s Footprint Has Many Negative Impacts On Performance Redundant footprint is a significant element of cost management problems (as well as CapEx and working capital issues) and has contributed to Retail’s failure to generate operating leverage Duplicative locations have resulted in redundant direct costs (headcount, facilities, maintenance, insurance) and increased organizational costs (district and regional management layers with ~50 office locations) Redundant locations have resulted in excess capital deployment: Duplicative safety-stock inventory to support overlapping locations, while fewer branches would allow for better demand management with lower aggregate inventory Duplicative CapEx for equipment / maintenance at multiple locations Management compensation incentives and performance targets that are linked to EBITDA dollars – with no reference to return on capital – prioritize pursuit of growth at any price and disincent focus on high-return margin improvement initiatives like footprint optimization The persistence of Retail’s footprint overlap – which Agrium has previously acknowledged – illustrates the need to add distribution experience to the board to prioritize key initiatives, improve performance and unlock value “We don’t need the number of facilities we have out there we need to have fewer facilities” – Agrium Retail President, Agrium 2012 Investor Day III. Root Causes Of Underperformance Root Cause #1: Cost Management 52

Result: Declining Margins And Failure To Generate Operating Leverage Margin Decline Despite Growth In Scale Retail Margin (EBIT / Gross Profit) “Significant opportunities remain to grow organic revenues and improve operating leverage. There remains an opportunity for the retail segment (70% of revenues) to improve margins by 200bps [JANA note: represents ~$230 million EBIT] or more based on 1) reducing costs, 2) fixed asset optimization/rationalization, 3) improvements in the Australian business, and 4) an increase in private label crop protection sales.” – Credit Suisse, 3/1/13 III.

What Agrium Hides From Investors: EBIT / Gross Profit Margins (%) Comparison of Retail’s performance based on true margins – EBIT / Gross Profit – tells the real story: Agrium has not delivered on margins despite “synergistic” M&A, significant growth in scale and an improved ag environment. Agrium Defends Its Performance By Citing Misleading Metrics (Cont’d) III.

Why Would Agrium Want To Show Performance Comparisons Based On EBITDA / Revenue Margins? UAP’s wholesale business UAP had a large wholesale (two step) distribution business UAP leveraged its scale and buying power to procure products for sale to smaller retailers This was extremely attractive, because UAP captured a spread on the volume, and earning that spread required very little additional time or resources from UAP However, it was lower Gross Profit / Revenue margin than traditional ag retail distribution While wholesale was a high EBIT / Gross Profit margin and high ROIC business, its lower Gross Profit / Revenue profile weighed down UAP’s overall EBIT / Revenue margins Growth in Retail CapEx CapEx / Gross Profit was historically ~4-6% for Agrium Retail and for UAP on a reported basis (less than 4% on an adjusted basis)(1) CapEx began to grow significantly post UAP, increasing to 10% of Gross Profit in 2010 Agrium suspended Retail CapEx disclosure in 2011 By showing margins based on EBITDA rather than EBIT, Agrium does not ‘charge’ itself for the cost of increased capital deployed in Retail, even though that capital supports the generation of additional Revenue and Gross Profit III.

Agrium’s Capital Allocation Before & After JANA III. Root Causes Of Underperformance Root Cause #3: Capital Allocation Note: Dividend payout ratio reflects current annualized dividend per share / consensus NTM earnings per share as of March 6, 2013, except where noted. Earnings per share data per CapitalIQ. (1) Reflects Watsco’s 2012 actual dividend of $2.48 per share. Given uncertainties regarding potential changes to U.S. federal tax policy, in 2012 Watsco paid a one-time special dividend of $5.00 per share, pulling forward ~2 years of future dividend payments. Given the pull forward, Watsco reduced its Q1 2013 quarterly dividend to $0.25 per share (from $0.62 in 2012). Capital Allocation: 5 Years Pre-JANA Total Buybacks & Dividends Comparable Dividend Payout Ratio: Agrium vs. Retail & Wholesale Peers Prior to JANA’s involvement, Agrium prioritized growth and M&A at the expense of returning capital to shareholders.

Agrium’s Dutch Tender Share Repurchase III. Root Causes Of Underperformance Root Cause #3: Capital Allocation Agrium’s board either was not paying attention to results or elected to pursue the buyback knowing it had a negative quarterly announcement coming in only ~2 weeks By failing to pre-announce its quarter (which it had done before, as seen in Q3 2009) and extend its tender offer, Agrium missed the opportunity to repurchase a larger number of shares at a lower price Execution of the buyback under these circumstances illustrates the need for a more owner-orientated perspective on Agrium’s board 2 4 3 1 Agrium Share Price (C$) Agrium’s reckless execution of its Dutch tender – its first meaningful buyback in a decade, which came when the board faced criticism on capital allocation discipline – illustrates the board’s willingness to sacrifice shareholder capital to avoid real change. August 2, 2012: Agrium announced C$900 million Dutch tender repurchase, its first meaningful buyback in a decade, which was managed by Morgan Stanley Ahead of the repurchase, Agrium did a global roadshow to promote its performance, strategy and new commitment to transparency, but failed to pre-announce its pending earnings miss October 19, 2012: Agrium executed its C$900 million buyback at C$103 / share November 7, 2012: Agrium announced earnings that significantly missed expectations, causing a 1 day drop in the stock of 11% to C$95 4 1 2 3 66

Agrium’s Retail Comparables “Switcheroo” The Retail Comparables Switcheroo evidences that Agrium never really evaluated its structure and instead used a rigged process to argue for the status quo.

Root Causes Of Underperformance Root Cause #4: Conglomerate Structure When challenged by JANA to unlock Retail’s value, Agrium instead changed its long-standing valuation comparable set to talk down its value potential Agrium’s Original Comparables for Retail were clearly more appropriate Regularly cited by Agrium (e.g., 2011 Investor Day and 2011 ‘White Paper’ published for sell-side) Used by UAP in its 10-K to measure share price performance vs. peers (and UAP outperformed them) Valued in-line with UAP – at ~9x EBITDA – for the 2 years preceding sale to Agrium Agrium’s new lower multiple Midnight Comparables included newly public companies, micro caps with limited liquidity, controlled companies, and companies with dissimilar business mixes / cyclical exposures Prices paid for $4+ billion of M&A – including UAP at ~13x EBITDA and Landmark at ~15x – can only be justified by reference to Agrium’s Original Comparables Agrium’s switch to the Midnight Comparables means either: Agrium’s board sat idly by and allowed acquisitions at inflated valuations: Agrium commented to Reuters that the board “hadn’t really done that much work”(1) on valuing Retail before JANA Or, Agrium’s board never honestly evaluated its corporate structure with an eye to maximizing value, and instead sought to avoid a debate by deliberately talking down Retail’s value 72

Agrium’s Midnight Comparables Were Indefensible Company Key Observations On Comparability Size / Mult.(1) $2.3bn / 7.8x $0.6bn / 6.5x $3.8bn / 6.1x $5.6bn / 8.0x $1.2bn / 8.3x $6.0bn / 8.4x (1) Represents Market Capitalization and TEV / NTM EBITDA multiples as of August 2, 2012 (date Morgan Stanley and Agrium’s board reviewed Retail valuation, per Agrium’s August 20, 2012 investor update presentation). Data per CapitalIQ. Similar business model, size, liquidity, trading and index inclusion (S&P 500) characteristics Highly applicable business model comparable, ‘breaking bulk’ of products with cyclical, commodity exposure × However, an inapplicable valuation comparable, as listed in continental Europe, where valuations are typically lower than for comparable US companies × Small cap, with only $1.2 billion market cap when cited as a comp × Poor liquidity, trading ~$14 million per day at the time × End markets heavily exposed to construction cycles × End market demand very cyclical and less attractive, with high exposure to non-residential construction × Provides manufacturing services that are capital intensive and less attractive than pure distribution × Control shareholder owns 53% × Micro cap, with only ~$600 million market cap at the time cited as a comp × Poor liquidity, trading only ~$3 million per day at the time × End markets more cyclical, heavy service center component × Had been a public company for less than 4 months when cited as a comp × Control shareholder owns 77% at the time × Poor liquidity, trading ~$7 million per day at the time × End markets exposed to energy CapEx cycles “We fail to understand why the board has apparently chosen to disregard Agrium’s own list of comparable companies in favor of a newer group that appears less appropriate, more spurious and more convenient.” - Bank of America, 1/29/13 III. Root Causes Of Underperformance Root Cause #4: Conglomerate Structure 73

Agrium’s Valuation Contortions III. Root Causes Of Underperformance Root Cause #4: Conglomerate Structure (1) SOTP discount to report date share price for analysts who utilize SOTP in their primary valuation methodology. When pressed to unlock Retail’s value, Agrium first attempted to “close the valuation gap” by talking down Retail’s value by discarding long-held comps and introducing lower valued “Midnight” comps Then, Agrium attempted to talk down Wholesale’s value to argue that Retail is appropriately valued At its 2013 Investor Day, Agrium undervalued Wholesale at $8.6bn by valuing the $0.5bn+ already invested in its much-lauded Vanscoy expansion at $0, by valuing AAT / Resale at less than its invested capital, by ignoring liquidity and risk by employing a “Midnight” Russian Phosphate comp (PhosAgro) and by ignoring Agrium’s statutory tax rate advantage to certain peers Following criticism of this attempt to talk down Wholesale’s value, Agrium has resorted to specious and inconsistent arguments to justify its depressed view of Wholesale’s value (see 2/19/13 presentation) Agrium has discarded basic tenets of corporate finance in arguing that its lower statutory tax rate should not be a factor in determining an appropriate EBITDA-based valuation – even though it means Agrium generates higher after-tax free cash flow per dollar of EBITDA earned Agrium now seeks to justify valuing its $500mm+ non-productive investment in Vanscoy at $0 by asserting peer multiples must be adjusted for the full cost of their expansion projects, but Potash Corp. has completed 80% of its 2003 expansion and most of it is already on-line, and CF has not incurred material expenditures (and, unlike Vanscoy, its projects will not adversely impact operating results from required shutdowns in operations) While it attempts to discredit JANA’s critiques of its valuation contortions by pointing to sell-side analysts, Agrium chooses to employ a SOTP that is not followed by any of its analysts, who themselves show a SOTP discount of ~$20 per share(1) Agrium has shown it will employ any valuation approach necessary to avoid an unrigged review of its corporate structure. Shareholders deserve a better process. 74

Conglomerate Structure: Not Just A Valuation Question III. Root Causes Of Underperformance Root Cause #4: Conglomerate Structure (1) “Potash Forecast Trails Estimates Amid Plan for More Shutdowns”; Bloomberg; Christopher Donville; January 31, 2013. (2) Agrium quantifies benefit from integration for existing Potash production at $375mm, and states that integration has resulted in an average 104k tonnes of additional production per year over the past 3 years. Agrium values Potash at 7.5x EBITDA in its implied Retail valuation (2013 Investor Day Presentation, slide 92), implying $50mm of EBITDA generated as a result of integration. This implies $481 / tonne of realized EBITDA, almost 100% of Agrium’s realized Potash sale price in North America even before inclusion of Potash tax. Claimed synergies (market intelligence, ability to conduct superior M&A and to enter new markets more successfully) – are not evidenced in results Sub-par returns on capital, inventory write-downs, Landmark integration issues Claimed higher Potash operating rates reflect smaller size relative to Potash Corp. and Mosaic (allows Agrium to free ride on their capacity shutdowns), not integration Potash Corp’s “role as the key global swing producer often results in the company bearing a disproportionate amount of the burden when reduced global demand necessitates supply curtailments” – Susquehanna analyst Don Carson(1) Claimed value benefit to Agrium implies Potash margins of ~100% of revenues!(2) Any benefit could be replicated via commercial arrangement Limited Benefits Disadvantageous for both businesses, compromising procurement, customer relationships and flexibility Retail competes with Wholesale’s customers Wholesale competes with Retail’s key suppliers Stuffing Retail with inventory, introducing volatility into a business valued for its stability Different optimal capitalization / capital allocation Different natural investor / research analyst followings Persistent conglomerate discount Excess corporate overhead Leads to underperformance (Morgan Stanley’s view when representing CF) For these reasons, all key competitors have actively rejected the integrated model Significant Issues Agrium’s conglomerate structure has significant negative consequences while appearing to provide limited offsetting benefits. 75

Given the magnitude of the potential opportunity to unlock value from Agrium’s corporate structure, shareholders deserve an unrigged review. This is a question on which “reasonable people can disagree,” (Globe & Mail, 3/8/13) and which Agrium’s CEO called “a good question to ask.” (Globe & Mail, 1/31/13) Such a review may or may not lead to the ultimate conclusion that Retail should be spun off. We believe – based on publicly available information – that it will support a split, but our nominees will accept the results no matter what, and in any case would only be a minority of the board Agrium’s “Trojan Horse” scare tactic is presented on the basis that other current Agrium directors might agree with a new, unrigged review

Failed Board Oversight Talking Down Value (Aug. 2012): Agrium abandons its prior comp set for new lower multiple comps (“Switcheroo”), using same bankers who argued against its strategy for CF. CEO later says Agrium hired these bankers, who were billed as conducting an independent review, because they “had experience with JANA” and noted that CF’s CEO “was very happy with them” (Credit Agricole / CLSA, 11/5/12) Wasting Shareholder Capital to Fight (Oct. 2012): Agrium executes first large repurchase in years, but in an apparent effort to keep the stock price high and/or cause JANA to tender, declines to first guide shareholders to expect a known impending earnings miss (contrary to past practice) Above Explaining (Oct. – Dec. 2012): Agrium declines to respond to issues raised by JANA in any substantive detail until January, other than to cite its flawed structural review and claim JANA will fail Skewed Views on Governance (Jan. 2013): CEO says “It is not typical to bring someone on the board who tells you your strategy is flawed and indirectly tells you you’re incompetent” – (Globe & Mail 1/29/13) Later says “We also said to JANA that we have a number of members retiring and we are constantly upgrading our board, and we’ll be looking at who we want to bring on our board over the next couple of months and we’ll make those appropriate decisions” (BNN Interview 1/29/13) Refusal to Accept Even Faint Criticism (Feb. 2013): In settlement talks, Agrium refuses to commit to even watered-down language committing to simply reviewing JANA’s issues Cutting Short The Debate (Feb. 2013): At 5pm on the Friday before a holiday weekend, Agrium moves up meeting date by over a month, and CEO later publicly says “we want to get this behind us.” Non-Substantive Attacks (Feb. 2013): CEO publicly calls JANA a “pain in the arse” Padding Director Resumes (Mar. 2013): In its 2013 proxy, Agrium simply checks “Distribution” box for two long-serving directors who did not have this experience the year before and have no claim to it No Board Involvement (current): JANA has never heard from a single independent director III. Root Causes Of Underperformance Root Cause #5: Corporate Governance 79

A History Of Misleading Claims Regarding “Distribution Experience” On Agrium’s Board The Missing Years (2007 – 2012): Agrium spent over $4 billion dollars on Retail acquisitions despite not having a single board member with legitimate ‘breaking bulk’ distribution experience, incorrectly claiming in its proxy circular that directors with primarily oil and gas pipeline experience meet this need “No Shortcomings” (January 2013): When asked by the Wall Street Journal whether there were any board shortcomings related to Retail experience as JANA has pointed out, Agrium’s CEO responds “No” “Shortcomings, But We Fixed Them” (February 2013): In a reversal, Agrium then adds 2 new directors it claims address this deficiency, but neither possesses significant ‘breaking bulk’ distribution experience “We Checked This Box” (March 2013): Agrium gives up and just checks the “Distribution” box for two long-serving directors who did not have this experience the year before and have no credible claim to it Qualification Matrix – 2012 Proxy Qualification Matrix –2013 Proxy Agrium needs to stop looking for easy fixes and add real ‘breaking bulk’ distribution experience to its board. III. Root Causes Of Underperformance Root Cause #5: Corporate Governance 80

Agrium’s Refusal To Acknowledge Opportunities For Improvement Agrium has steadfastly refused to acknowledge any opportunities for improvement. III. Root Causes Of Underperformance Root Cause #5: Corporate Governance After Agrium proposed a settlement offer to JANA, we asked that: 1. Agrium’s two anonymous director candidates, once-identified, would – along with a JANA candidate – fully address the key deficiencies on Agrium’s board 2. Agrium would commit itself to addressing key issues raised by JANA Costs: Engage consultant to evaluate Retail's branch footprint and corporate overhead Controls: Review Retail senior management compensation objectives and targets Capital Allocation: Communicate a target for dividend payout ratio or some other mechanism to clarify ongoing capital return plans Corporate Structure: Retain a new investment bank to perform a review of Agrium’s corporate structure and recommend ways to enhance shareholder value Agrium said it was categorically unwilling to agree to any of the above steps When Agrium revealed the names of their two director candidates it was clear that they did not bring the experience Agrium had claimed and presumably were screened for acquiescence to the status quo David Everitt: segment manager with a manufacturing / supply chain background; does not bring ‘breaking bulk’ distribution experience Mayo Schmidt: track record of poor cost management, de minimis capital return and limited distribution experience; a dollar invested over Mr. Schmidt’s CEO tenure would be worth a fraction of that amount today 81

Defining Director “Independence” NYSE Listed Company Manual: “No director qualifies as ‘independent’ unless the board of directors affirmatively determines that the director has no material relationship with the listed company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the company)” (303A.02). NYSE Commentary: “[A]s the concern is independence from management, the Exchange does not view ownership of even a significant amount of stock, by itself, as a bar to an independence finding” Agrium’s Corporate Governance Guidelines: “A Director is an independent director if the Board has affirmatively determined that the Director has no material relationship with the Corporation (directly, through family relationships, or as a partner, shareholder, or officer of an organization that has a relationship with the Corporation)” (II.B) 2013 US & Canadian ISS Guidelines: Defines “Affiliated Outside Director” by listing numerous relationships with the company National Instrument 52-110 (Canadian Securities Regulation): “[A director] is independent if he or she has no direct or indirect material relationship with the issuer.” Director independence has always been defined by examining relationships with the management they are meant to oversee, not alignment with shareholders for good reason. III. Root Causes Of Underperformance Root Cause #5: Corporate Governance 83

Director Alignment with Shareholders Board entanglements with the management they oversee is a conflict. Board alignment with shareholders is not, provided it is no different than exposure to stock (direct ownership, options, RSU’s, DSU’s, etc.) JANA’s nominees are 100% aligned with all shareholders by virtue of: Substantial personal investments for non-JANA nominees (comparable or in some cases far higher than many current Agrium directors who have been board members for years) Sharing in a percentage of JANA’s returns for non-JANA nominees; 100% formulaic, non-discretionary, based on share price. Stock exposure, pure and simple. No obligation to JANA or to pursue any particular path, bound only by fiduciary duty to all shareholders. Directors always have different levels of stock exposure and can realize gains at various points For example, 20-year board member Frank Proto has sold all shares acquired through option exercises – in almost all cases selling his shares immediately upon exercise, and his share ownership has declined from 30,000 shares in 2003 to 8,300 currently, and 11-year board member Dr. Susan Henry exercised 10,000 options in 2010 and sold all those shares on the same day Mr. Proto and current board chair Victor Zaleschuk will see the vast majority of their equity at risk (82% and 94% respectively) be redeemed after they retire in 2014 and 2015, respectively Not a criticism, just pointing out fallacy of argument that incentives create undue ‘short term’ bias It is true that JANA bears this expense, but JANA bears every expense of this campaign which has substantially benefitted shareholders There is always a risk that directors will act on a short-term basis (and proxy rules require all relationships to be disclosed), which is why shareholders must review each nominee’s track record and reputation. Our director nominees are – and will remain – 100% aligned with all shareholders. III. Root Causes Of Underperformance Root Cause #5: Corporate Governance 84

Other Perspectives The same mix of personal investments and stock-based incentive was employed with our CNET slate, which was favorably received by shareholders, with RiskMetrics remarking that “[A] strong activist slate will gain traction with shareholders.” (2008-2009 M&A and Proxy Fight Review) Agrium has called such incentive-based alignment previously “unheard of in Canada,” which may be true, but the same considerations apply in Canada as in the US Agrium cites “board advocates” (not shareholder advocates) identified by the Globe & Mail: (1) consultant founder of “two complementary advisory firms serving an international clientele of corporate leaders,” (2) CEO of Institute of Corp. Directors (ICD), an “association representing Canadian directors and boards,” and (3) an academic who mistakenly suggests such incentives are discretionary There are many examples in Canada and elsewhere where directors actually do receive discretionary compensation from shareholders of the company (unlike JANA’s non-discretionary, formulaic approach linked entirely to share price), including companies where Agrium directors are or were on the board(1) We are not suggesting such appointments are in any way improper. We are pointing out the hypocrisy of the company’s attack. III.

New Agrium Board Appointee “Prior to approaching Viterra, Glencore struck ‘side-car’ agreements to divest some Viterra units to Agrium Inc.” The Financial Post, January 31, 2013 Appointment of Mr. Schmidt, who as Viterra’s CEO received C$30MM in a transaction which Agrium helped to facilitate which ended in Agrium buying Viterra’s distribution business, comes much closer to raising legitimate independence questions. 2013 US & Canadian ISS Guidelines: Defines “Affiliated Outside Director” by listing numerous relationships with the company, including “Former executive of the company, an affiliate, or a firm acquired within the past three years.” National Instrument 52-110 (Canadian Securities Regulation): “[A]n individual who accepts, directly or indirectly, any consulting, advisory or other compensatory fee from the issuer or any subsidiary entity of the issuer, other than as remuneration for acting in his or her capacity as a member of the board of directors or any board committee, or as a part-time chair or vice-chair of the board or any board committee is considered to have a material relationship with the issuer.” III.

Agrium’s Substantial Value Creation Potential Retail savings potential of more than $200 million (~15% of NA cost base) from optimizing footprint, associated regional/divisional offices costs and restoring margins, with additional savings from enhanced distribution practices. Corporate savings potential of $50+ million from addressing bloated cost base that has grown 14% p.a. Substantial value creation through improved disclosure, institution of appropriate performance metrics and proper alignment of management incentives with shareholder value creation Substantial value creation from more disciplined M&A and investment practices, directing additional capital toward pursuing a share shrink ahead of realizing value creation plan, a clearer commitment to prioritizing capital return and releasing at least $725 million of working capital, ~$500 million more than Agrium’s new $250 million target Fresh, unbiased review of Agrium’s structure based on all the facts could result in the elimination of Agrium’s significant and persistent conglomerate discount (~$20 / share) Given several troubling lapses in corporate governance, shareholders can only benefit from adding nominees to the board who will bring an enhanced shareholder mindset and relevant experience to protect shareholders The magnitude of the opportunities evident from the outside suggests Agrium’s true value creation potential is likely significantly larger than we have identified.

Horner Oversight: Served on board for over 8 years, thus overseeing Agrium’s relative underperformance and failure to pursue basic shareholder-friendly measures. Serves on compensation committee, which prioritized growth at any cost over profitability in setting Retail management incentives Relevance of Experience: Currently a corporate director, previously CEO of paper and forest products company (Catalyst Paper) that suffered repeated losses, prompting shareholder intervention and his departure; has cited distribution experience for years despite largely pulp and paper manufacturing experience Governance: Chair of governance committee, which condoned scorched earth defense of the status quo Member of special committee tasked with responding to the numerous issues JANA raised (which arose during his tenure); instead approved assault on a reasonable debate about unlocking shareholder value Shareholder Alignment: No purchases of stock in 5 years 97

Henry (1) Agrium attempts to portray this critique as an attack on Dr. Henry’s personal finances. This is untrue. It is simply illustrative of the fact that Dr. Henry has cashed out amounts far greater than she has personally invested. 98

Agrium’s Directors Targeted for Removal Lack Value Creation Track Records, Relevant Experience And Shareholder Orientation (Cont’d) V. JANA’s Board Nominees Mayo M. Schmidt Oversight: N/A, appointed February 2013 Relevance of Experience: Currently a corporate director, formerly Viterra CEO Does not bring significant distribution experience as Viterra retail distribution represented < 15% of EBITDA and served to support core grain handling business Like Agrium, Viterra exhibited alarming growth in corporate costs, including 20%+ growth every year from F2007 – F2011 Governance: Appointed after Agrium CEO stated that questioning Agrium’s performance or strategy was a disqualification for board service Made C$30mm+ in transaction where Agrium acquired Viterra’s retail business, further calling into question his independence Shareholder Orientation: $1 invested with Mr. Schmidt at the start of his 12-year CEO tenure would be worth cents on the dollar when he sold the Company As CEO, issued $2bn+ in equity, repurchased $0 stock and only initiated a small dividend after shareholder pressure Purchased 1,500 shares upon appointment to the board “We suspect that when Agrium went looking for its own alternatives, it probably found very few serious distribution executives interested in running against the JANA slate.” – Credit Agricole / CLSA, 2/13/13 99

JANA’s Nominees: Independent & Aligned with All Shareholders Independent Independent under Canadian securities laws, NYSE rules, and Agrium’s own guidelines “Independence” defined by relationship to company, not shareholders, for good reason Each will have a fiduciary duty once elected to serve all Agrium shareholders Aligned with All Agrium shareholders Once elected, each nominee will only gain to the extent all shareholders gain Substantial JANA investment (~$1.2 billion) Substantial personal investments by non-JANA nominees (~$14 million collectively) Incentive for non-JANA nominees based solely on Agrium stock performance Incentive is stock exposure, pure and simple 100% formulaic based on stock price, not discretionary, like a DSU or option 3-year end date JANA bears this expense, but that is true of all the expenses of this campaign, which has already been of significant benefit to all Agrium shareholders The five director nominees are aligned with all shareholders and will work with the full board to create value at Agrium.
