Attention:  Mr. Wayne Smith

Dear Sirs:

Revolving Line of Credit

On  the  basis  of  information   provided  by  Imagis  Technologies  Inc.  (the
"Borrower"),  Altaf Nazerali (the "Lender") hereby  establishes in favour of the
Borrower a revolving  line of credit  (the "Line of  Credit")  on the  following
terms and conditions:

Maximum Credit Amount:  The lesser of Cdn.  $200,000 or the total of the current
outstanding  Trade  Account  Receivables  (as defined in the Security  Agreement
(hereinafter  defined) that are expected to be  collectible  within 60 days (the
"Maximum Credit Amount")

Borrowing and Repayment:  The Borrower may borrow,  repay and reborrow up to the
Maximum  Credit Amount  outstanding  at any one time,  provided that any amounts
received from the  collection of Trade  Account  Receivables  are applied to any
outstanding balance of the Line of Credit.

Purpose:  The Borrower  will use the proceeds of the Line of Credit to assist in
its cash flow management.

Term:  The term of the Line of Credit  shall  commence  on  February 1, 2003 and
expire on the earlier of May 31, 2003 or on  completion  of an equity  financing
and the Borrower  will repay the Line of Credit and interest  thereon in full on
the earlier of May 31, 2003 or receipt of funds pursuant to an equity financing.

Interest Rate: The Borrower shall pay interest on the outstanding  daily balance
of the Line of Credit at a  floating  rate  equal at all times to the Prime Rate
plus 2.0% per annum calculated  monthly,  not in advance, on the basis of a year
of 365 days.  The  interest  rate  shall  fluctuate  as and when the Prime  Rate
fluctuates.

Default  Interest Rate:  Notwithstanding  the previous  paragraph,  the Borrower
shall pay  interest on any amount of principal or interest on the Line of Credit
which is not paid  when  due at the  Prime  Rate  plus 5% per  annum  calculated
monthly not in advance, on the basis of a year of 365 days. The default interest
shall fluctuate as and when the Prime Rate fluctuates.

Prime Rate: In this agreement,  "Prime Rate" means the floating  commercial loan
reference rate of Royal Bank of Canada  publicly  announced from time to time as
its "prime rate" or "reference

<PAGE>

                                     - 2 -

rate"  (calculated  on the basis of actual number of days elapsed over a year of
365 days),  with any change in the Prime  Rate to be  effective  on the date the
"prime  rate" or  "reference  rate"  changes.  For the  purposes  of the  Canada
Interest  Act,  the annual rate of  interest to which an interest  rate which is
calculated on the basis of a year of 365 days is equivalent is the interest rate
multiplied by the number of days in the year and divided by 365.

Payment of Business  Interest:  The Borrower shall pay interest  accruing due in
each calendar month on the 10th business day of the next calendar month.

Evidence of  Indebtedness:  As evidence  of the  indebtedness  under the Line of
Credit,  the  Borrower  will deliver to the Lender a grid  promissory  note (the
"Note") in the principal amount of $200,000.  The Lender is hereby authorized to
record on the Note all  advances  by the Lender  under the Line of  Credit,  all
interest accrued thereon and all payments of principal and interest thereon made
by the Borrower. The Note will constitute prima facie evidence of the amounts of
all such advances,  interest and payments and the  indebtedness  of the Borrower
under the Line of Credit from time to time.

Security:  As security for its  obligations to the Lender in connection with the
Line of Credit,  the Borrower  will  deliver to the Lender a Security  Agreement
(the  "Security  Agreement")  creating a security  interest over the  Borrower's
trade account receivables,  subject only to the security interests held by Royal
Bank of Canada and AIG Credit Corporation of Canada ("Permitted Encumbrances").

Reporting Requirements: The Borrower will deliver to the Lender a monthly report
of outstanding  receivables with a reconciliation  of payments made and received
to substantiate all amounts deposited by the Borrower into the Line of Credit.

Other Covenants: The Borrower will:

     (a)  not grant,  create,  assume or permit to exist any  mortgage,  charge,
          lien,  pledge,  security  interest  or other  encumbrance  against any
          assets or rights of the Borrower or guarantee or become liable for the
          obligations  of any other person,  corporation  or other entity except
          those that are Permitted Encumbrances; and

     (b)  conduct  its  business  in  compliance  with all  applicable  laws and
          regulations,   including  without   limitation  laws  and  regulations
          relating  to  the  environment  and  hazardous,   toxic  or  dangerous
          substances.

Default: The following shall constitute events of default by the Borrower:

     (a)  non-payment  within 10  business  days  after the due date  thereof of
          principal,  interest and any other  amounts due under this  Agreement,
          the Note or the Security Agreement;

     (b)  a breach or default by the Borrower under this Agreement, the Security
          or any other agreement with the Lender which is not remedied within 14
          days after the date of such occurrence;

<PAGE>

                                     - 3 -

     (c)  if the Borrower  defaults under any other obligation to repay borrowed
          money;

     (d)  if in the opinion of the Lender there is a material  adverse change in
          the financial condition, ownership or operation of the Borrower;

     (e)  if proceedings for the  dissolution,  liquidation or winding-up of the
          Borrower or for the  suspension of the  operations of the Borrower are
          commenced,  unless such  proceedings are being actively and diligently
          contested by the Borrower in good faith; or

     (f)  in the  event of the  bankruptcy,  liquidation  or  insolvency  of the
          Borrower or if a receiver or  receiver-manager is appointed for all or
          any part of the business or assets of the Borrower; and

     (g)  if the Borrower ceases to carry on business.

Upon the occurrence of one or more events of default, the Lender may declare the
outstanding  principal  and  accrued  interest  under  the Line of  Credit to be
immediately  due and payable and the Lender may exercise its remedies  under the
Security Agreement or otherwise available to the Lender at law or in equity.

Expenses:  The Borrower  will pay all costs and expenses  incurred  from time to
time  in  preparation,  negotiation  and  execution  of this  Agreement  and the
Security,  and  any  costs  and  expenses  incurred  in  the  administration  or
enforcement of this Agreement or any other agreement relating to this Agreement.

Attention:  Mr. Wayne Smith

Dear Sirs:

Amended and Restated Loan Agreement: Revolving Line of Credit

Further to the loan agreement made between  Imagis  Technologies  Inc. and Altaf
Nazerali  dated  February 21, 2003 (the "Loan  Agreement"),  Altaf Nazerali (the
"Lender")  wishes to increase the maximum  amount of credit  available to Imagis
Technologies   Inc.  (the  "Borrower)   under  the  Loan  Agreement  and  hereby
establishes  in favour of the  Borrower an amended and restated  loan  agreement
(the "Amended and Restated Loan  Agreement") for a revolving line of credit (the
"Extended Line of Credit") on the following terms and conditions:

Maximum Credit Amount: Cdn. $500,000 (the "Maximum Credit Amount")

Borrowing and Repayment:  The Borrower may borrow,  repay and reborrow up to the
Maximum  Credit Amount  outstanding  at any one time,  provided that any amounts
paid to and received are applied to any outstanding balance of the Extended Line
of Credit.

Purpose:  The Borrower  will use the proceeds of the Extended  Line of Credit to
assist in its cash flow management and general working capital.

Term:  The term of the Extended Line of Credit shall  commence on April 15, 2003
and  expire  on the  earlier  of May 31,  2003  or on  completion  of an  equity
financing  and the Borrower  will repay the Extended Line of Credit and interest
thereon in full on the earlier of May 31,  2003 or receipt of funds  pursuant to
an equity financing.

Interest Rate: The Borrower shall pay interest on the outstanding  daily balance
of the  Extended  Line of Credit at a  floating  rate  equal at all times to the
Prime Rate plus 2.0% per annum calculated monthly,  not in advance, on the basis
of a year of 365 days.  The interest rate shall  fluctuate as and when the Prime
Rate fluctuates.

Default  Interest Rate:  Notwithstanding  the previous  paragraph,  the Borrower
shall pay interest on any amount of  principal or interest on the Extended  Line
of  Credit  which  is not paid  when due at the  Prime  Rate  plus 5% per  annum
calculated  monthly  not in  advance,  on the basis of a year of 365  days.  The
default interest shall fluctuate as and when the Prime Rate fluctuates.

Prime Rate: In this agreement,  "Prime Rate" means the floating  commercial loan
reference rate of Royal Bank of Canada  publicly  announced from time to time as
its "prime rate" or "reference  rate"  (calculated on the basis of actual number
of days elapsed  over a year of 365 days),  with any change in the Prime Rate to
be effective on the date the "prime rate" or "reference rate" changes.

<PAGE>

                                     - 2 -

For the  purposes  of the Canada  Interest  Act,  the annual rate of interest to
which an interest rate which is calculated on the basis of a year of 365 days is
equivalent is the interest rate multiplied by the number of days in the year and
divided by 365.

Payment of Business  Interest:  The Borrower shall pay interest  accruing due in
each calendar month on the 10th business day of the next calendar month.

Evidence of  Indebtedness:  As evidence of the  indebtedness  under the Extended
Line of Credit,  the Borrower will deliver to the Lender an amended and restated
grid  promissory  note (the "Note") in the  principal  amount of  $500,000.  The
Lender is hereby  authorized  to record on the Note all  advances  by the Lender
under the Extended Line of Credit, all interest accrued thereon and all payments
of principal and interest thereon made by the Borrower. The Note will constitute
prima facie evidence of the amounts of all such advances,  interest and payments
and the indebtedness of the Borrower under the Extended Line of Credit from time
to time. The Note will amend and restate the grid promissory note dated February
21, 2003, created and issued by the Borrower to the Lender.

Security:  As security for its  obligations to the Lender in connection with the
Extended  Line of  Credit,  the  Borrower  will  deliver to the Lender a General
Security Agreement (the "Security  Agreement") creating a security interest over
all of the  Borrower's  present  and  after-acquired  personal  property  and an
uncrystalized  floating  charge on land,  subject only to the existing  security
interests  held by Royal Bank of Canada as security  for  corporate  Visa credit
cards for a maximum credit amount of $56,000 ("Permitted  Encumbrances"),  which
security  interests  are  currently in good  standing and not in default and the
Borrower has not received any notice of default thereunder.

Additional  Security:  As additional  collateral security for the obligations to
the Lender,  the Borrower will execute and deliver to the Lender the Source Code
Escrow Agreement dated April 15, 2003.

Reporting Requirements: The Borrower will deliver to the Lender a monthly report
of outstanding  receivables with a reconciliation  of payments made and received
to substantiate all amounts  deposited by the Borrower into the Extended Line of
Credit.

Other Covenants: The Borrower will:

     (a)  not grant,  create,  assume or permit to exist any  mortgage,  charge,
          lien,  pledge,  security  interest  or other  encumbrance  against any
          assets or rights of the Borrower or guarantee or become liable for the
          obligations  of any other person,  corporation  or other entity except
          those that are Permitted Encumbrances; and

     (b)  conduct  its  business  in  compliance  with all  applicable  laws and
          regulations,   including  without   limitation  laws  and  regulations
          relating  to  the  environment  and  hazardous,   toxic  or  dangerous
          substances.

Mutual  Covenants:  The Borrower and Lender will within 5 business days from the
date hereof,  execute and deliver to the Escrow Agent appointed  pursuant to the
provisions  of the Source  Code  Escrow  Agreement  hereinabove  referred  to, a

Escrow Agent in accordance with the terms, conditions and

will consist of an appropriate  form of licence  containing the essential  terms
described in Schedule A hereto.

          principal,  interest and any other  amounts due under this  Agreement,
          the Note or the Security Agreement;

     (b)  a breach or default by the Borrower under this Agreement, the Security
          or any other agreement with the Lender which is not remedied within 14
          days after the date of such occurrence;

     (c)  if the Borrower  defaults under any other obligation to repay borrowed
          money; (d) if in the opinion of the Lender there is a material adverse
          change in the financial  condition,  ownership,  effective  control or
          operation of the Borrower;

     (e)  if proceedings for the  dissolution,  liquidation or winding-up of the
          Borrower or for the  suspension of the  operations of the Borrower are
          commenced,  unless such  proceedings are being actively and diligently
          contested by the Borrower in good faith; or

     (f)  in the  event of the  bankruptcy,  liquidation  or  insolvency  of the
          Borrower or if a receiver or  receiver-manager is appointed for all or
          any part of the business or assets of the Borrower; and

     (g)  if the Borrower ceases to carry on business.

Upon the occurrence of one or more events of default, the Lender may declare the

be  immediately  due and payable and the Lender may exercise its remedies  under
the Security Agreement or otherwise available to the Lender at law or in equity.
