Energy Loan Portfolio 11 Key Takeaways • $3.1 billion of outstanding balances at 9/30/2014 • 8% of loans • 34% Upstream, 31% Oilfield Service, 18% Midstream, 13% Energy Service Manufacturing, 4% Other (see slide 12) • Balances up a modest 1.7% year over year at September 30, 2014 • Internal concentration limits result in more measured growth • Conservative underwriting also contributes to more measured growth • Underwriting of upstream includes several risk mitigants (see slides 13 - 15) • Underwriting of Energy Service portfolio includes low leverage and strong, stable equity sponsors (see slide 16) • Less than 1% peak annual energy loan losses in the wake of the last large oil price decline • Balanced Production: 49% of borrowers are “Oil Intensive” (produced more oil than gas) • Internal sensitivity analysis uses prices of mid-$50s for 8 quarters • Sensitivity and portfolio analysis indicates potential risk rating downgrades may drive additional modest loan loss reserves.

Conservative Underwriting: What We Do, and What We Avoid 13 Source: Company Documents What We Do: • Upstream lending – multiple “haircuts” on oil / gas values and commodity prices to arrive at borrowing base (loan commitment amount) • Semi-annual borrowing base redeterminations and sensitivity testing to ensure proper equity cushion throughout the life of the loan • Energy services loans generally have limited leverage ratios • Sponsors are frequently long-standing, dedicated private equity firms, not generalists PE firms that may not fully understand the risks What We Avoid: • Borrowers who employ too much leverage, even if much of the debt is subordinate to ours • Borrowers with complex equity structures, especially where competing interests among equity groups/classes could delay or derail additional capital infusions • Management teams that are inexperienced and/or unproven • Energy service companies in the most cyclically sensitive parts of the industry: seismic companies, small independent drilling contractors and saltwater disposal services

Upstream (Reserve-Based) Underwriting 15 Typical Oil & Gas Reserve-Based Loan $100 - Value of oil & gas reserves using current NYMEX oil and gas prices $ 85 - Zions’ risk-adjusted value of reserves (apply risk factors to non- producing reserves) $ 77 - Apply “bank price deck” (generally ~90% of NYMEX) to determine collateral value. $ 54 - Loan commitment amount (30% haircut if 25%+ of reserves are hedged) $ 46 - Loan commitment amount (40% haircut if no hedging) Notes: • Collateral value is based on engineering firm assessment of oil/gas reserves. For lending purposes, no more than 25% of the collateral may be comprised of non- producing reserves. Cash flows from the reserves are calculated by employing engineer’s projected volumes, bank oil/gas price deck and actual operating costs, then converted to present value using a 9% discount rate. • Utilization rate typically runs near 50% on the loan commitment amount.

Energy Services – Key Credit Metrics 16 How We Mitigate Risk in Energy Service Lending • Conservative Capital Structures • Average Senior Debt / EBITDA: 2.0x or less (a covenant is generally tripped if ratio rises to 3.0x) • Average Debt / Capitalization: less than 50% • Strong sponsorship / access to capital • Private Equity firms sponsor a large portion of the energy loan portfolio; PE firms are typically dedicated to the energy industry, rather than generalists. • Dedicated PE sponsors: ~80% of total sponsors • Generalist PE sponsors: all have a significant amount of capital committed to the energy industry • Large portion of portfolio consists of publicly traded companies with strong balance sheets and access to multiple sources of capital • Geographically diversified client base with operations across most major basins • Most borrowers have significant operations in both oil and gas basins • Private companies without equity sponsors are typically very well capitalized with strong management teams (many have personal recourse or sponsorship from high net worth families) Source: Company Documents

One-Year Outlook Summary Relative to 3Q14 Results Topic Outlook Comment Loan Balances Slightly to Moderately Increasing • Prepayments remain volatile, making net loan growth difficult to forecast Net Interest Income Slightly Increasing • Primarily driven by debt reduction late in 3Q14 • Zions expects to invest approximately $1.2 billion of its money market investments into other high-quality liquid assets over the course of the next year, primarily in short- to medium-duration government agency mortgage-backed securities. Provisions Modestly Negative • Includes Provisions for Loan Losses & Reserve for Unfunded Loan Commitment • 4Q14 reserve may reflect decline in value and increase in volatility in oil prices Fee Income Increasing • Excluding securities gains/losses, fee income initiatives likely to result in moderate increase Noninterest Expense Stable • Higher expenses stemming from loan/deposit/accounting systems upgrade, offset by reduced credit-related NIE and subsiding FDIC Indemnification Asset amortization • Excludes the effect of debt extinguishment costs and provision for unfunded lending commitments 35
