change.

|WELLS FARGO BANK |  | REVOLVING LINE OF CREDIT NOTE
|---------------- |  | -----------------------------
|                
|$10,000,000.00   |  | Reno, Nevada
April 2, 2002   

FOR VALUE RECEIVED, the undersignedGameTech International, Inc. and Bingo Technologies Corporation("Borrower")
promises to pay to the order of WELLS FARGO BANK, NATIONAL ASSOCIATION ("Bank") at its office atReno RCBO, 5340 Kietzke Lane, Suite 201, Reno, NV
89511, or at such other place as the holder hereof may designate, in lawful money of the United States of America and in immediately available funds, the principal sum of $10,000,000.00, or so much thereof as may be advanced and be outstanding, with interest thereon, to be computed on each advance from the date of its
disbursement as set forth herein.

DEFINITIONS:

As used herein, the following terms shall have the meanings set forth after each, and any other term defined in this Note shall have the meaning set forth at the
place defined:

(a)  "Business
Day" means any day except a Saturday, Sunday or any other day on which commercial banks in Nevada are authorized or required by law to close.

(b)  "Fixed
Rate Term" means a period commencing on a Business Day and continuing for1, 2 or 3 months, as designated by
Borrower, during which all or a portion of the outstanding principal balance of this Note bears interest determined in relation to LIBOR; provided however, that no Fixed Rate Term may be selected for
a principal amount less than$500,000.00; and provided further, that no Fixed Rate Term shall extend beyond the scheduled maturity date hereof. If any
Fixed Rate Term would end
on a day which is not a Business Day, then such Fixed Rate Term shall be extended to the next succeeding Business Day.

(c)  "LIBOR"
means the rate per annum (rounded upward, if necessary, to the nearest whole 1/8 of 1%) determined by dividing Base LIBOR by a percentage equal to 100% less any
LIBOR Reserve Percentage.



(d)  "Prime
Rate" means at any time the rate of interest most recently announced within Bank at its principal office as its Prime Rate, with the understanding that the Prime
Rate is one of Bank's base rates and serves as the basis upon which effective rates of interest are calculated for those loans

making reference thereto, and is evidenced by the recording thereof after its announcement in such internal publication or publications as Bank may designate.

INTEREST:

(a)Interest.The outstanding principal balance of this Note shall bear interest (computed on the basis of a 360-day year, actual days elapsed) either (i) at a
fluctuating rate per annumequal tothe Prime
Rate in effect from time to time, or (ii) at a fixed rate per annum determined by Bank to be2.00000%above LIBOR in effect on the first day of
the applicable Fixed Rate Term. When interest is determined in relation to the Prime Rate, each change in the rate of interest hereunder shall become effective on the date each Prime Rate change is
announced within Bank. With respect to each LIBOR selection option
selected hereunder, Bank is hereby authorized to note the date, principal amount, interest rate and Fixed Rate Term applicable thereto and any payments made thereon on Bank's books and records (either
manually or by electronic entry) and/or on any schedule attached to this Note, which notations shall be prima facie evidence of the accuracy of the information noted.

(b)Selection of Interest Rate Options.At any time any portion of this Note bears interest determined in relation to LIBOR,
it may be continued by Borrower at the end of the Fixed Rate Term applicable thereto so that all or a portion thereof bears interest determined in relation to the Prime Rate or to LIBOR for a new
Fixed Rate Term designated by Borrower. At any time any portion of this Note bears interest determined in relation to the Prime Rate, Borrower may convert all or a portion thereof so that it bears
interest determined in relation to LIBOR for a Fixed Rate Term designated by Borrower. At such time as Borrower requests an advance hereunder or wishes to select a LIBOR option for all or a portion of
the outstanding principal balance hereof, and at the end of each Fixed Rate Term, Borrower shall give Bank notice specifying: (i) the interest rate option selected by Borrower; (ii) the
principal amount subject thereto; and (iii) for each LIBOR selection, the length of the applicable Fixed Rate Term. Any such notice may be given by telephone (or such other electronic method as
Bank may permit) so long as, with respect to each LIBOR selection, (A) if requested by Bank, Borrower provides to Bank written confirmation thereof not later than three (3) Business Days after
such notice is given, and (B) such notice is given to Bank prior to 10:00 a.m. on the first day of the Fixed Rate Term, or at a later time during any Business Day if Bank, at it's sole
option but without obligation to do so, accepts Borrower's notice and quotes a fixed rate to Borrower. If Borrower does not immediately accept a fixed rate when quoted by Bank, the quoted rate shall
expire and any subsequent LIBOR request from Borrower shall be subject to a redetermination by Bank of the applicable fixed rate. If no specific designation of interest is made at the time any advance
is requested hereunder or at the end of any Fixed Rate Term, Borrower shall be deemed to have made a Prime Rate interest selection for such advance or the principal amount to which such Fixed Rate
Term applied.

(c)Taxes and Regulatory Costs.Borrower shall pay to Bank immediately upon demand, in addition to any other amounts due or
to become due hereunder, any and all (i) withholdings, interest equalization taxes, stamp taxes or other taxes (except income and franchise taxes) imposed by any domestic or foreign
governmental authority and related in any manner to LIBOR, and (ii) future, supplemental, emergency or other changes in the LIBOR Reserve Percentage, assessment rates imposed by the Federal
Deposit Insurance Corporation, or similar requirements or costs imposed by any domestic or foreign governmental authority or resulting from compliance by Bank with any request or directive (whether or
not having the force of law) from any central bank or other governmental authority and related in any manner to LIBOR to the extent they are not included in the calculation of LIBOR. In determining
which of the foregoing are attributable to any LIBOR option available to Borrower hereunder, any reasonable allocation made by Bank among its operations shall be conclusive and binding upon Borrower.

2

---

(d)Payment of Interest.Interest accrued on this Note shall be payable on the2ndday of eachmonth, commencingMay 2, 2002.

(e)Default Interest.From and after the maturity date of this Note, or such earlier date as all principal owing hereunder
becomes due and payable by acceleration or otherwise, the outstanding principal balance of this Note shall bear interest until paid in full at an increased rate per annum (computed on the basis of a 360-day year, actual days elapsed) equal to 4% above the rate of interest from time to time applicable to this Note.

BORROWING AND REPAYMENT:

(a)Borrowing and Repayment.Borrower may from time to time during the term of this Note borrow, partially or wholly repay
its outstanding borrowings, and reborrow, subject to all of the limitations, terms and conditions of this Note and of any document executed in connection with or governing this Note; provided however,
that the total outstanding borrowings under this Note shall not at any time exceed the principal amount stated above. The unpaid principal balance of this obligation at any time shall be the total
amounts advanced hereunder by the holder hereof less the amount of principal payments made hereon by or for any Borrower, which balance may be endorsed hereon from time to time by the holder. The
outstanding principal balance of this Note shall be due and payable in full onApril 2, 2003.

(b)Advances.Advances hereunder, to the total amount of the principal sum available hereunder, may be made by the holder at
the oral or written request of (i)Chief Executive Officer or Chief Financial Officer, any one acting alone, who are authorized to request
advances and direct the disposition of any advances until written notice of the revocation of such authority is received by the holder at the office designated above, or (ii) any person, with
respect to advances deposited to the credit of any deposit account of any Borrower, which advances, when so deposited, shall be conclusively presumed to have been made to or for the benefit of each
Borrower regardless of the fact that persons other than those authorized to request advances may have authority to draw against such account. The holder shall have no obligation to determine whether
any person requesting an advance is or has been authorized by any Borrower.

(c)Application of Payments.Each payment made on this Note shall be credited first, to any interest then due and second, to
the outstanding principal balance hereof. All payments credited to principal shall be applied first, to the outstanding principal balance of this Note which bears interest determined in relation to
the Prime Rate, if any, and second, to the outstanding principal balance of this Note which bears interest determined in relation to LIBOR, with such payments applied to the oldest Fixed Rate Term
first.

PREPAYMENT:

(a)Prime Rate.Borrower may repay principal on any portion of this Note which bears interest determined in relation to the
Prime Rate at any time, in any amount and without penalty.

(b)LIBOR.Borrower may prepay principal on any portion of this Note which bears interest determined in relation to LIBOR at
any time and in the minimum amount of$500,000.00; provide however, that if the outstanding principal balance of such portion of this Note is less than
said amount, the minimum prepayment amount shall be the entire outstanding principal balance thereof. In consideration of Bank providing this prepayment option to Borrower, or if any such portion of
this Note shall become due and payable at any time prior to the last day of the Fixed Rate Term applicable thereto by acceleration or otherwise, Borrower shall pay to Bank immediately upon demand a
fee which is the sum of the discounted monthly differences for each month from the month of prepayment through the month in which such Fixed Rate Term matures, calculated as follows for each such
month:

3

---



Each
Borrower acknowledges that prepayment of such amount may result in Bank incurring additional costs, expenses and/or liabilities, and that it is difficult to ascertain the full extent of such
costs, expenses and/or liabilities. Each Borrower, therefore, agrees to pay the above-described prepayment fee and agrees that said amount represents a reasonable estimate of the prepayment costs,
expenses and/or liabilities of Bank. If Borrower fails to pay any prepayment fee when due, the amount of such prepayment fee shall thereafter bear interest until paid at a rate per annum 2.000%above
the Prime Rate in effect from time to time (computed on the basis of a360-day year,
actual days elapsed). Each
change in the rate of interest on any such past due prepayment fee shall become effective on the date each Prime Rate change is announced within Bank.

EVENTS OF DEFAULT:

The occurrence of any of the following shall constitute an "Event of Default" under this Note:

(a)  The
failure to pay any principal, interest, fees or other charges when due hereunder or under any contact, instrument or document executed in connection with this Note.

(b)  The
filing of a petition by or against any Borrower, any guarantor of this Note or any general partner or joint venturer in any Borrower which is a partnership or a
joint venture (with each such guarantor, general partner and/or joint venturer referred to herein as a "Third Party Obligor") under any provisions of the Bankruptcy Reform Act, Title 11 of the
United States Code, as amended or recodified from time to time, or under any similar or other law relating to bankruptcy, insolvency, reorganization or other relief for debtors; the appointment of a

which any Borrower or Third Party Obligor has incurred any obligation for borrowed money, any purchase obligation, or any other liability of any kind to any person or entity, including the holder.

(e)  Any
financial statement provided by any Borrower or Third Party Obligor to Bank proves to be incorrect, false or misleading in any material respect.

sums of principal and interest outstanding hereunder to be immediately due and payable without presentment, demand, notice of nonperformance, notice of protest, protest or notice of dishonor, all of
which are expressly waived by each Borrower, and the obligation, if any, of the holder to extend any further credit hereunder shall immediately cease and terminate. Each Borrower shall pay to the
holder immediately upon demand the full amount of all payments, advances, charges, costs and expenses, including reasonable attorneys' fees (to include outside counsel fees and all allocated costs of

this Note, and the prosecution or defense of any action in any way related to this Note, including without limitation, any action for declaratory relief, whether incurred at the trial or appellate
level, in an arbitration proceeding or otherwise, and including any of the foregoing incurred in connection with any bankruptcy proceeding (including without limitation, any adversary proceeding,
contested matter or motion brought by Bank or any other person) relating to any Borrower or any other person or entity.
