----- Start of picture text ----- KEY TERMSThe Notes offer the potential for a variable return while providing contingent protection against a slight to moderate decline in the Solactive CanadaInsurance AR Index (the “ Reference Index ”) over the term of the Notes. The Principal Amount is NOT protected under these Notes.AnnualAutoCall  Issuer: Bank of Montreal. Medium Term: 7-year term to maturity (subject to the Notes being automatically called by the Bank).Feature  Reference Index: The Solactive Canada Insurance AR Index is an adjusted return index. It aims to track the gross total return performance ofthe Solactive Canada Insurance Index TR (the “ Underlying Index ”), calculated in CAD less an adjusted return factor of 120 index points perannum that will be calculated daily in arrears (the “Adjusted Return Factor” ). The Closing Level on January 31, 2022 was 3,041.10. TheAdjusted Return Factor divided by the Closing Level was therefore equal to 3.95% on January 31, 2022. Over the term of the Notes, the sum ofthe Adjusted Return Factor will be approximately 841 index points, representing 27.64% of the Closing Level on January 31, 2022. TheLinked to Underlying Index is a gross total return index that reflects the price changes of its constituent securities and the reinvestment in the index ofSolactive Canada any dividends and distributions paid in respect of such securities. For the calculation of the level of the Underlying Index, any dividends orother distributions paid on the constituent securities of the Underlying Index are assumed to be reinvested across all the constituent securitiesInsurance AR Indexof the Underlying Index. AutoCall Feature: The Notes will be automatically called by the Bank if the Closing Level is equal to or above the AutoCall Level (i.e., 100% ofthe Initial Level) on any Valuation Date. If the automatic call feature is triggered, Holders will receive payment of the Principal Amount, plus aVariable Return that increases each Valuation Date. If the Closing Level is never equal to or above the AutoCall Level on any Valuation Date, theNotes will not be automatically called by the Bank and there will be no Variable Return paid on the Notes.Potential  Potential Variable Return: The Notes will be automatically called by the Bank if the Closing Level is equal to or above the AutoCall Level on anyVariable Return Valuation Date. If the automatic call feature is triggered, Holders will receive payment of the Principal Amount plus a Variable Return thatincreases each Valuation Date. Fixed Return: in Year 1: 9.00%; Year 2: 18.00%; Year 3: 27.00%; Year 4: 36.00%; Year 5: 45.00%; Year 6: 54.00%; Year 7: 63.00% ; (or anannualized return of 9.00%, 8.59%, 8.28%, 7.98%, 7.71%, 7.45% and 7.22%, respectively). Contingent Protection: If the Index Return is negative, the Principal Amount will be protected so long as the Final Level is equal to or above theBarrier Level (i.e., 75% of the Initial Level) . If the Final Level is below the Barrier Level, the Maturity Payment will be equal to the PrincipalAmount reduced by an amount equal to the Index Return (which will be a negative amount reflecting the decline in the Closing Level), subject25% Contingent to the Minimum Payment Amount. The calculation and timing of the payments at Maturity may be adjusted upon the occurrence of certainspecial circumstances.Protection Daily Secondary Market: Provided by BMO Capital Markets (may be subject to an early trading charge of up to 3.00% declining to zero afterat Maturity 180 days from the Issue Date and other limitations as described in the Prospectus).

Variable Return

Subject to the occurrence of an Extraordinary Event, if the Closing Level is equal to or above the AutoCall Level on any Valuation Date, a Holder will be entitled to receive a Variable Return calculated using the following formula:

Principal Amount × (Fixed Return + Excess Return)

Valuation Date	Fixed Return	Annualized Return	Excess Return(Index Return > Fixed Return)
Call Valuation Date(Year 1)	9.00%	9.00%	(Index Return - 9.00%)× 5.00%
Call Valuation Date(Year 2)	18.00%	8.59%	(Index Return - 18.00%)× 5.00%
Call Valuation Date(Year 3)	27.00%	8.28%	(Index Return - 27.00%)× 5.00%
Call Valuation Date(Year 4)	36.00%	7.98%	(Index Return - 36.00%)× 5.00%
Call Valuation Date(Year 5)	45.00%	7.71%	(Index Return - 45.00%)× 5.00%
Call Valuation Date(Year 6)	54.00%	7.45%	(Index Return - 54.00%)× 5.00%
Final Valuation Date(Year 7)	63.00%	7.22%	(Index Return - 63.00%)× 5.00%

If the Index Return is less than or equal to the Fixed Return and the Closing Level is equal to or above the AutoCall Level on the relevant Valuation Date, then the Excess Return will be zero and the Variable Return will equal the Principal Amount multiplied by the relevant Fixed Return. See “Description of the Notes — Variable Return” and “Additional Risk Factors Specific to the Notes” in the Prospectus.

BMO AutoCallable Notes, Series 1887 (CAD) Linked to Solactive Canada Insurance AR Index

HOW DO THE NOTES WORK?

The following hypothetical examples demonstrate how the Maturity Payment will be calculated and determined under four different scenarios. In each scenario below, it has been assumed that an investor purchased and continues to hold $10,000.00 worth of Notes (or 100 Notes). The hypothetical Closing Levels used in these examples are for illustrative purposes only and should not be construed in any way as estimates or forecasts of the future performance of the Reference Index or the return that a Holder might realize on the Notes. All hypothetical examples assume that no events described under “Special Circumstances” in the Prospectus, have occurred during the term.

Initial Level = 2,900.00 Barrier Level = 2,175.00 (75% of the Initial Level) AutoCall Level = 2,900.00 (100.00% of the Initial Level)

Example 1: Principal Loss at Maturity

==> picture [290 x 120] intentionally omitted <==

==> picture [186 x 8] intentionally omitted <==

----- Start of picture text ----- — Reference Index  Closing Level on Valuation Date----- End of picture text -----

Valuation Date	Closing Level
1	1,711.00
2	841.00
3	812.00
4	928.00
5	899.00
6	986.00
7	1,015.00

In this hypothetical scenario, the Final Level is below the Barrier Level, so a Holder will receive a Maturity Payment equal to the Principal Amount reduced by an amount equal to the Index Return on the Final Valuation Date (which will be a negative amount reflecting the decline in the Closing Level), subject to the Minimum Payment Amount.

Closing Level on Final Valuation Date = 1,015.00

Index Return = (Final Level – Initial Level) / Initial Level

= (1,015.00 - 2,900.00) / 2,900.00 = -65.00%

Maturity Payment = Principal Amount + (Principal Amount × Index Return)

= $100.00 + ($100.00 × -65.00%) = $35.00 per Note.

Assuming a principal investment of $10,000.00 (or 100 Notes), a Holder will receive a Maturity Payment of $3,500.00 on the Maturity Date (equal to a 65.00% loss on the $10,000.00 principal investment or an annualized loss of 13.92%).

Example 2: Contingent Protection at Maturity

==> picture [290 x 119] intentionally omitted <==

==> picture [186 x 8] intentionally omitted <==

----- Start of picture text ----- — Reference Index  Closing Level on Valuation Date----- End of picture text -----

Valuation Date	Closing Level
1	1,711.00
2	841.00
3	812.00
4	754.00
5	2,204.00
6	2,610.00
7	2,508.50

In this hypothetical scenario, the Final Level is below the AutoCall Level, but above the Barrier Level, so there is no Variable Return payable on the Notes and a Holder will receive a Maturity Payment equal to the Principal Amount.

Closing Level on Final Valuation Date = 2,508.50

Index Return = (Final Level – Initial Level) / Initial Level

= (2,508.50 - 2,900.00) / 2,900.00 = -13.50%

Maturity Payment = Principal Amount = $100.00 per Note.

Assuming a principal investment of $10,000.00 (or 100 Notes), a Holder will receive a Maturity Payment of $10,000.00 on the Maturity Date (or an annualized return of 0.00%).

3	2,552.00
4	2,436.00
5	2,407.00
6	2,871.00
7	3,857.00

In this hypothetical scenario, the Final Level is above the AutoCall Level, thus triggering the Notes to be automatically called by the Bank. A Holder will receive a Maturity Payment equal to the Principal Amount, plus the Variable Return.

Fixed Return on Final Valuation Date = 63.00%

Index Return = (Final Level – Initial Level) / Initial Level

= (3,857.00 - 2,900.00) / 2,900.00 = 33.00%

An Index Return of 33.00% is less than the Fixed Return on the Final Valuation Date, so there is no Excess Return reflected in the Variable Return payable on the Maturity Date.

Variable Return = Principal Amount × (Fixed Return + Excess Return)

= $100.00 × (63.00% + 0.00%) = $63.00

Maturity Payment = Principal Amount + Variable Return = $100.00 + $63.00 = $163.00 per Note.

Assuming a principal investment of $10,000.00 (or 100 Notes), a Holder will receive a Maturity Payment of $16,300.00 on the Maturity Date (or an annualized return of 7.22%).

Example 4: Note Automatically Called before Maturity

Valuation Date	Closing Level
1	1,276.00
2	3,770.00

----- Start of picture text ----- — Reference Index  Closing Level on Valuation Date----- End of picture text -----

In this hypothetical scenario, the Final Level is above the AutoCall Level on the second Call Valuation Date, thus triggering the Notes to be automatically called by the Bank. A Holder will receive a Maturity Payment equal to the Principal Amount, plus the Variable Return on the Call Date.

Fixed Return on second Call Valuation Date = 18.00%

Index Return = (Final Level – Initial Level) / Initial Level

= (3,770.00 - 2,900.00) / 2,900.00 = 30.00%

An Index Return of 30.00% is higher than the Fixed Return on the second Call Valuation Date. Holder will benefit from the Excess Return reflected in the Variable Return payable on the Call Date.

Excess Return = (Index Return – Fixed Return) × Participation Rate

= (30.00% - 18.00%) × 5.00% = 0.60%

Variable Return = Principal Amount × (Fixed Return + Excess Return)

= $100.00 × (18.00% + 0.60%) = $18.60

Maturity Payment = Principal Amount + Variable Return = $100.00 + $18.60 = $118.60 per Note.

Assuming a principal investment of $10,000.00 (or 100 Notes), a Holder will receive a Maturity Payment of $11,860.00 on the Call Date (or an annualized return of 8.87%). The Notes will be cancelled and a Holder will not be entitled to receive any subsequent payments in respect of the Notes.
