Exhibit 1 to Amendment to Rights Agreement

EXHIBIT C

TRICO BANCSHARES

SUMMARY OF SERIES AA PREFERRED STOCK
PURCHASE RIGHTS

On June 12, 2001, the Board of Directors of TriCo Bancshares (the “Company”) declared a dividend of one preferred share purchase right (a “Right”) for each outstanding share of common stock, no par value (the “Common Stock”). The dividend is payable to the stockholders of record on July 10, 2001.

Our Board has adopted the Rights Agreement (as amended, the “Rights Agreement”) to protect stockholders from coercive or otherwise unfair takeover tactics. In general terms, it works by imposing a significant penalty upon any person or group that acquires 15% or more of our outstanding common stock without the approval of our Board. The Rights Agreement should not interfere with any merger or other business combination approved by our Board. For those interested in the specific terms of the Rights Agreement as made between our Company and Mellon Investor Services LLC (operating with the service name BNY Mellon Shareowner Services), a New Jersey limited liability company as the Rights Agent, on June 25, 2001, as amended, we provide the following summary description. Please note, however, that this description is only a summary, and is not complete, and should be read together with the entire Rights Agreement, which has been filed with the Securities and Exchange Commission as an exhibit to a Registration Statement on Form 8-A dated July 8, 2011. A copy of the Rights Agreement is available free of charge from our Company.

THE RIGHTS.

Our Board authorized the issuance of a Right with respect to each share of Common Stock outstanding on July 10, 2001. The Rights will initially trade with, and will be inseparable from, the Common Stock. New Rights will accompany any new shares of Common Stock we issue after July 10, 2001, until the Distribution Date described below.

EXERCISE PRICE.

Each Right will allow its holder to purchase from our Company one one-hundredth of a share of Series AA Junior Participating Preferred Stock (“Preferred Stock”) for $49.00, once the Rights become exercisable. This portion of a share of Preferred Stock will give the shareholder approximately the same dividend, voting, and liquidation rights as would one share of Common Stock. Prior to exercise, the Right does not give its holder any dividend, voting, or liquidation rights.

EXERCISABILITY.

The Rights will not be exercisable until:

•

10 days after the public announcement that a person or group has become an “Acquiring Person” by obtaining beneficial ownership of 15% or more of our outstanding Common Stock, or, if earlier,

•

10 business days (or a later date determined by our Board before any person or group becomes an Acquiring Person) after a person or group begins a tender or exchange offer which, if completed, would result in that person or group becoming an Acquiring Person.

We refer to the date when the Rights become exercisable as the “Distribution Date.” Until that date, the Common Stock certificates will also evidence the Rights, and any transfer of shares of Common Stock will constitute a transfer of Rights. After that date, the Rights will separate from the Common Stock and be evidenced by book-entry credits or by Rights certificates that we will mail to all eligible holders of Common Stock. Any Rights held by an Acquiring Person are void and may not be exercised.

CONSEQUENCES OF A PERSON OR GROUP BECOMING AN ACQUIRING PERSON.

•

FLIP IN. If a person or group becomes an Acquiring Person, all holders of Rights except the Acquiring Person may, for $49.00, purchase shares of our Common Stock with a market value of $98.00, based on the market price of the Common Stock prior to such acquisition.

•

FLIP OVER. If our Company is later acquired in a merger or similar transaction after the Rights Distribution Date, all holders of Rights except the Acquiring Person may, for $49.00, purchase shares of the acquiring corporation with a market value of $98.00, based on the market price of the acquiring corporation’s stock, prior to such merger.

PREFERRED STOCK PROVISIONS.

Each whole share of Preferred Stock, if issued:

•

will not be redeemable.

•

will entitle holders to quarterly dividend payments of $1 per share, or an amount equal to 100 times the dividend paid on one share of Common Stock, whichever is greater.

•

will entitle holders upon liquidation either to receive $100 per share or an amount equal to 100 times the payment made on one share of Common Stock, whichever is greater. will have the same voting power as 100 shares of Common Stock and will vote as a single class with the Common Stock.

•

if shares of our Common Stock are exchanged via merger, consolidation, or a similar transaction, will entitle holders to a per share payment equal to the payment made on one hundred shares of Common Stock.

The value of one one-hundredth interest in a share of Preferred Stock should approximate the value of one share of Common Stock.

EXPIRATION.

The Rights will expire on July 10, 2021.

REDEMPTION.

Our Board may redeem the Rights for $0.01 per Right at any time before any person or group becomes an Acquiring Person. If our Board redeems any Rights, it must redeem all of the Rights. Once the Rights are redeemed, the only right of the holders of Rights will be to receive the redemption price of $0.01 per Right. The redemption price will be adjusted if we have a stock split or stock dividends of our Common Stock.

EXCHANGE.

After a person or group becomes an Acquiring Person, but before an Acquiring Person owns 50% or more of our outstanding Common Stock, our Board may extinguish the Rights by exchanging one share of Common Stock or an equivalent security for each Right, other than Rights held by the Acquiring Person.

ANTI-DILUTION PROVISIONS.

Our Board may adjust the purchase price of the Preferred Stock, the number of shares of Preferred Stock issuable and the number of outstanding Rights to prevent dilution that may occur from a stock dividend, a stock split, a reclassification of the Preferred Stock or Common Stock. Adjustments to the purchase price of less than 1% will be deferred until the earlier of three years after the transaction requiring the adjustment or the date the right to exercise the Rights expires.

AMENDMENTS.

The terms of the Rights Agreement may be amended by our Board without the consent of the holders of the Rights. After a person or group becomes an Acquiring Person, our Board may not amend the Rights Agreement in any way that adversely affects the holders of the Rights.
