Senior Medium-Term Notes, Series A

Reverse Exchangeable Notes

Each Linked to the Common Equity Securities of a

Single Reference Stock Issuer

This pricing supplement relates to two separate note offerings. Each issue of the notes is linked to one, and only one, Reference Stock. You may participate in either of the two offerings or, at your election, in both of the offerings. This pricing supplement does not, however, allow you to purchase a single note linked to a basket of both of the Reference Stocks described below.

The notes are designed for investors who seek an interest rate that is higher than that of a conventional debt security with the same maturity issued by us or an issuer with a comparable credit rating. Investors should be willing to forgo the potential to participate in the appreciation of the applicable Reference Stock, be willing to accept the risks of owning the common equity securities of the applicable Reference Stock Issuer, and be willing to lose some or all of their principal at maturity.

·	Investing in the notes is not equivalent to investing in the shares of any of the Reference Stocks.

Each issue of the offered notes will pay interest monthly at the fixed rate specified for that issue below. However, the notes do not guarantee any return of principal at maturity. Instead, the payment at maturity will be based on the Final Stock Price of the applicable Reference Stock and whether the closing price of the applicable Reference Stock has declined from the applicable Initial Stock Price during the Monitoring Period, as described below.

·	RevEx 0054 will have a term of approximately three months, and RevEx 0055 will have a term of approximately six months.

·	Any payment at maturity is subject to the credit risk of Bank of Montreal.

·	Payment at maturity for each $1,000 principal amount note will be either a cash payment of $1,000 or delivery of shares of the applicable Reference Stock (or, at our election, the applicable Cash Delivery Amount), in each case, together with any accrued and unpaid interest, as described below.

·	The notes will be issued in minimum denominations of $1,000 and integral multiples of $1,000.

·	Our subsidiary, BMO Capital Markets Corp., is the agent for this offering. See “Supplemental Plan of Distribution—Conflicts of Interests” below.

Investing in the notes involves risks, including those described in the “Selected Risk Considerations” section beginning on page P-3 of this pricing supplement, page PS-4 of the product supplement, page S-1 of the prospectus supplement and on page 5 of the prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these notes or passed upon the accuracy of this pricing supplement, the product supplement, the prospectus supplement or the prospectus. Any representation to the contrary is a criminal offense.

The notes will be our unsecured obligations and will not be savings accounts or deposits that are insured by the United States Federal Deposit Insurance Corporation, the Bank Insurance Fund, the Canada Deposit Insurance Corporation or any other governmental agency or instrumentality or other entity.

We expect to deliver the notes through the facilities of The Depository Trust Company on January 24, 2011.

Selected Risk Considerations

An investment in the notes involves significant risks. Investing in the notes is not equivalent to investing directly in any of the Reference Stocks. These risks are explained in more detail in the “Additional Risk Factors Relating to the Notes” section of the product supplement dated December 3, 2010.

Your investment in the notes may result in a loss. — The notes do not guarantee any return of principal. The payment at maturity will be based on the applicable Final Stock Price and whether the closing price of the applicable Reference Stock has declined from the applicable Initial Stock Price to a closing price that is less than the applicable Trigger Price on any day during the Monitoring Period. Under certain circumstances, you will receive at maturity a number of shares of the applicable Reference Stock (or, at our election, the Cash Delivery Amount). We expect that the market value of those shares or the Cash Delivery Amount will be less than the principal amount of each note and may be zero. Accordingly, you could lose up to the entire principal amount of your notes.

Your return on the notes is limited to the principal amount plus accrued interest regardless of any appreciation in the value of the applicable Reference Stock. — You will not receive a payment at maturity with a value greater than your principal amount, plus accrued and unpaid interest. This will be the case even if the Final Stock Price exceeds the Initial Stock Price by a substantial amount.

Your investment is subject to the credit risk of Bank of Montreal. — Our credit ratings and credit spreads may adversely affect the market value of the notes. Investors are dependent on our ability to pay all amounts due on the notes on each interest payment date and at maturity, and therefore investors are subject to our credit risk and to changes in the market’s view of our creditworthiness. Any decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the value of the notes.

Potential conflicts. — We and our affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the notes. We and/or our affiliates may also currently or from time to time engage in business with the Reference Stock Issuers, including extending loans to, or making equity investments in, the Reference Stock Issuers, or providing advisory services to them. In addition, one or more of our affiliates may publish research reports or otherwise express opinions with respect to the Reference Stock Issuers, and these reports may or may not recommend that investors buy or hold shares of the Reference Stocks. As a potential purchaser of the notes, you should undertake an independent investigation of the applicable Reference Stock Issuer that in your judgment is appropriate to make an informed investment decision.

The inclusion of the underwriting commission and hedging profits, if any, in the original offering price of the notes, as well as our hedging costs, is likely to adversely affect the price at which you can sell your notes. — Assuming no change in market conditions or any other relevant factors, the price, if any, at which BMO Capital Markets Corp. or any other party may be willing to purchase the notes in secondary market transactions may be lower than the initial public offering price. The initial public offering price will include, and any price quoted to you is likely to exclude, the underwriting commission paid in connection with the initial distribution. The initial public offering price may also include, and any price quoted to you would be likely to exclude, the hedging profits that we expect to earn with respect to hedging our exposure under the notes. In addition, any such price is also likely to reflect a discount to account for costs associated with establishing or unwinding any related hedge transaction, such as dealer discounts, mark-ups and other transaction costs.

You will have no ownership rights in the applicable Reference Stock. — As a holder of the notes, you will not have any ownership interest or rights in the applicable Reference Stock, such as voting rights or dividend payments. In addition, the applicable Reference Stock Issuer will not have any obligation to consider your interests as a holder of the notes in taking any corporate action that might affect the value of the applicable Reference Stock and the notes.

P-3

No affiliation with the Reference Stock Issuers. — We are not affiliated with the Reference Stock Issuers. You should make your own investigation into the Reference Stocks and the Reference Stock Issuers. We are not responsible for any Reference Stock Issuer’s public disclosure of information, whether contained in SEC filings or otherwise.

Lack of liquidity. — The notes will not be listed on any securities exchange. BMO Capital Markets Corp. may offer to purchase the notes in the secondary market, but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. Because other dealers are not likely to make a secondary market for the notes, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which BMO Capital Markets Corp. is willing to buy the notes.

Hedging and trading in the Reference Stocks. — We or any of our affiliates may carry out hedging activities related to the notes, including in the Reference Stocks or instruments related to the Reference Stock. We or our affiliates may also trade in the Reference Stocks or instruments related to one or more of the Reference Stocks from time to time. Any of these hedging or trading activities as of the pricing date and during the term of the notes could adversely affect our payment to you at maturity.

Many economic and market factors will influence the value of the notes. — In addition to the value of the applicable Reference Stock and interest rates on any trading day, the value of the notes will be affected by a number of economic and market factors that may either offset or magnify each other, and which are described in more detail in the product supplement.

The Reference Stocks

All information contained herein on the Reference Stocks and on the Reference Stock Issuers is derived from publicly available sources and is provided for informational purposes only. Companies with securities registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) are required to periodically file certain financial and other information specified by the SEC.

We do not make any representation that these publicly available documents are accurate or complete. See the section “The Reference Stock Issuers” in the product supplement for additional information.

The hypothetical examples shown below are intended to help you understand the terms of the notes. The actual amount of cash or securities that you will receive at maturity will depend upon the Final Stock Price of the applicable Reference Stock, and whether its closing price was below the applicable Trigger Price on any trading day during the applicable Monitoring Period.

Examples of the Hypothetical Payment at Maturity for a $1,000 Investment in a Note.

The following table illustrates the hypothetical payments at maturity on a $1,000 investment in a note, based on a hypothetical Initial Stock Price of $100.00, a hypothetical Trigger Price of $80.00 (80.00% of the hypothetical Initial Stock Price), and a range of hypothetical Final Stock Prices and assuming that the closing price of the Reference Stock declines in the manner set forth in the column below, “Hypothetical Lowest Closing Price during the Monitoring Period.” The numbers appearing in the following table and examples have been rounded for ease of analysis.

Hypothetical Lowest Closing Price during the Monitoring Period	Hypothetical Lowest Closing Price during the Monitoring Period Expressed as a Percentage of the Initial Stock Price	Hypothetical Final Stock Price	Hypothetical Final Stock Price Expressed as a Percentage of the Initial Stock Price	Payment at Maturity	Total Value of Payment Received at Maturity*
$70.00	70%	$110.00	110%	$1,000.00	$1,000.00
$75.00	75%	$90.00	90%	10 shares of the Reference Stock or the Cash Delivery Amount	$900.00
$100.00	100%	$100.00	100%	$1,000.00	$1,000.00
$80.00	80%	$60.00	60%	10 shares of the Reference Stock or the Cash Delivery Amount	$600.00
$80.00	80%	$85.00	85%	$1,000.00	$1,000.00
$50.00	50%	$50.00	50%	10 shares of the Reference Stock or the Cash Delivery Amount	$500.00
$25.00	25%	$25.00	25%	10 shares of the Reference Stock or the Cash Delivery Amount	$250.00
$0.00	0%	$0.00	0%	10 shares of the Reference Stock or the Cash Delivery Amount	$0.00

Note that you will receive at maturity any accrued and unpaid interest in cash, in addition to either shares of the Reference Stock (or, at our election, the Cash Delivery Amount) or the principal amount of your notes in cash. Also note that if you receive the Physical Delivery Amount, the total value of the payment received at maturity shown in the table above includes the value of any fractional shares, which will be paid in cash.

P-7

The following examples illustrate how the total value of payments received at maturity set forth in the table above are calculated.

Example 1: The lowest closing price of the Reference Stock during the Monitoring Period was $70.00 but the Final Stock Price is $110.00. Because the Final Stock Price of $110.00 is greater than the Initial Stock Price of $100.00, you will receive a payment at maturity of $1,000 per $1,000 in principal amount of the notes, even though the Reference Stock closed at a price less than the Trigger Price during the Monitoring Period.

Example 2: The lowest closing price of the Reference Stock during the Monitoring Period was $75.00, which is less than the Trigger Price, and the Final Stock Price is $90.00, which is less than the Initial Stock Price. Because the Final Stock Price of $90.00 is less than the Initial Stock Price of $100.00 and the closing price of the Reference Stock declined to a closing price that is less than the Trigger Price of $80.00 on at least one trading day during the Monitoring Period, you will receive at maturity the Physical Delivery Amount (or, at our election, the Cash Delivery Amount). Because the Final Stock Price of the Reference Stock is $90.00, the total value of your final payment at maturity, whether in cash or shares of the Reference Stock, is $900.00 per $1,000 in principal amount of the notes.

Example 3: The closing price of the Reference Stock does not decline to a closing price that is less than the Trigger Price on any trading day during the Monitoring Period prior to the Valuation Date. However, the closing price of the Reference Stock on the Valuation Date is $60.00, which is less than the Trigger Price. Because the Final Stock Price of $60.00 is less than the Initial Stock Price of $100.00 and the Final Stock Price has declined to a closing price that is less than the Trigger Price of $80.00, you will receive the Physical Delivery Amount (or, at our election, the Cash Delivery Amount) at maturity. Because the Final Stock Price of the Reference Stock is $60.00, the total value of your final payment at maturity, whether in cash or shares of the Reference Stock, is $600.00 per $1,000 in principal amount of the notes.

Example 4: The Final Stock Price of $80.00 is less than the Initial Stock Price of $100.00 and the closing price of the Reference Stock does not decline to a closing price that is less than the Trigger Price on any day during the Monitoring Period. Because the closing price of the Reference Stock has not declined to a closing price that is less than the Trigger Price of $80.00, you will receive a payment at maturity of $1,000 per $1,000 in principal amount of the notes, even though the Final Stock Price of $80.00 is less than the Initial Stock Price of $100.00.

Regardless of the performance of the Reference Stock, or of the payment that you receive at maturity, you will receive the applicable interest payments over the term of the notes.
