             ITEM 9: SALES OF SECURITIES PURSUANT TO REGULATION S.

     Saf T Lok, Incorporated (the "Company") closed a Regulation S offering of
1,500,000 shares of common stock and two year stock purchase warrants for a
total of 2,500,000 shares of common stock (2,000,000 shares at $2.00 per share
exercise price and 500,000 shares at $3.00 per share exercise price) for a total
purchase price of $3,000,000 to three foreign purchasers on November 12, 1997.
Of this offering, 1,250,000 shares and warrants for 2,083,333 shares were
delivered to the foreign purchasers and the Company received gross proceeds of
$2,500,000.  The balance of the offering closed in escrow with 250,000 shares
and warrants for 416,667 shares (333,334 shares at $2.00 per share exercise
price and 83,333 shares at $3.00 per share exercise price) and $500,000 being
held in escrow.  If the Company is in compliance with all applicable regulatory
requirements on December 1, 1997, the $500,000 will be released to the Company
and the 250,000 shares and warrants for 416,667 shares (333,334 shares at $2.00
per share exercise price and 83,333 shares at $3.00 per share exercise price)
will be delivered to the foreign purchaser.  If the Company is not in compliance
with applicable regulatory requirements on December 1, 1997, the shares and
warrants will be returned to the Company and the cash ($500,000) will be
returned to the foreign purchasers.

     In connection with the placement of this sale of common stock to the
foreign purchasers, the investment banking firm of State Street Securities
received a fee of 13.5% of the sales price of the common stock sold to the
investors and $60,000 for legal fees.  State Street Securities will receive a
13.5% fee of the sales price of the stock underlying the warrants if the
warrants are exercised.  As required by the Placement Agreement with State
Street Securities, the Company intends to enter into a financial and management
consulting services agreement with A.B. & Associates, Inc. for a fee of $250,000
and a financial public relations agreement with Marketing Direct Concepts for a
fee of $375,000 payable upon execution and a fee of $375,000 payable upon the
receipt by the Company of the proceeds from the exercise of a minimum of
$1,500,000 of the stock purchase warrants.

     As a result of the Company's receipt of the net proceeds from the sale of
the 1,250,000 shares, as well as the recent conversion of all of the remaining
outstanding convertible debentures, the Company's stockholders' equity as of
November 12, 1997 was $3,143,003. As of November 12, 1997, the Company's total
assets were $3,921,539. The above noted stockholders' equity and total assets
amounts are reflected in the Unaudited Consolidated Balance Sheet attached
hereto as Exhibit 99.1.

     The Company is estimating its stockholders' equity and total assets on
November 12, 1997, for the purpose of satisfying certain listing qualifications
standards for the Nasdaq SmallCap Market.

<PAGE>
 
          (c) For a period of six months after the Closing, neither the Company
nor any direct or indirect subsidiary of the Company shall sell, offer to sell
or otherwise issue any "security" if within ten (10) business days after notice
to the Placement Agent of any such proposed offering, the Placement Agent
advises the Company or any affiliate thereof, as the case may be, that the
Placement Agent has received an opinion of its counsel to the effect that such
offering would adversely affect the qualification of the offer and sale of the
Common Stock and Warrants as a private offering transaction under Regulation S.

          (d)  Prior to and after the Closing, the Company shall deliver to the
Placement Agent, upon the written request of the Placement Agent, such

first negotiation to obtain equity financing on behalf of the Company on the

Placement Agent in writing of the terms of an offer for equity financing
proposed by the Company. The Placement Agent shall then have fifteen days to
provide the Company with a funding commitment to provide such equity financing
on the same terms. If the Placement Agent fails to provide such commitment, the
Company may proceed with such proposal (the "Proposed

                                       7

Financing"). If the Proposed Financing is not completed within six (6) months
thereafter, or if the terms of the Proposed Financing are materially changed to
the detriment of the Company, the Company shall be obligated to resubmit the
proposed terms to the Placement Agent and start the process again. During the
twelve (12) month period, the failure of the Placement Agent to exercise its
right of first negotiation shall not affect its right with respect to the
proposed equity financings during the twelve month period.

      9.  Indemnification.

           -------------------
time or in part from time to time (such partial exercises to be in amounts of 
not less than 25,000 Warrant Shares), on and after October 13, 1997, but prior 
to 5:00 P.M. on October 13, 1999, by the holder of this Warrant) the ("Holder") 
by the surrender of this Warrant (with the subscription form at the end hereof 
duly executed) at the principal office of the Company at 18245 SE Federal

or checks, payable to the order of the Company. If this Warrant is exercised in 
part, this Warrant must be exercised for a number of whole Warrant Shares, and 
the Holder is entitled to receive a new Warrant covering the number of Warrant 
Shares in respect of which this Warrant has not been exercised and setting forth
the proportionate part of the Aggregate Warrant Price applicable to such Warrant
Shares. Upon such surrender of this Warrant, the Company will (a) issue a 
certificate or certificates in the name of the Holder for the largest number of

(determined in such reasonable manner as the Board of Directors of the Company 
shall determine), and (b) deliver the other securities and properties receivable
upon the exercise of this Warrant, or the proportionate part thereof if this 
Warrant is exercised in part, pursuant to the provisions of this Warrant.

           -----------------------------
expiration of this Warrant, the Company will at all times have authorized and

        ---------------------------- 
        (a) If, at any time or from time to time after the date of this Warrant,

way of a stock dividend or stock split (including, without limitation, a reverse
stock split), then, and in each such case, the Per Share Warrant Price on the 
date of such stock dividend or stock split shall be adjusted, or further 
adjusted, to a price (to the nearest cent) determined by dividing (i) an amount 
equal to the number of Common Shares outstanding immediately prior to such 
issuance multiplied by the Per Share Warrant Price in effect immediately prior 
to such issuance by (ii) the total number of Common Shares outstanding 
immediately after such issuance. Upon each adjustment in the Per Share Warrant 
Price resulting from a stock split or stock dividend, the number of Warrant 
Shares shall be adjusted by dividing the Aggregate Warrant Price by the Per 
Share Warrant Price in effect immediately after such adjustment. Notice of each 
such adjustment and each such readjustment shall be forthwith mailed to the 
Holder.

        (b) If the Company shall be consolidated with or merged into another 
corporation, or shall sell all or substantially all of its assets in part of a 
reorganization to which the Company is a party within the meaning of the 
Internal Revenue Code of 1986, as presently in effect, or shall issue a security
convertible into its Common Shares as a dividend on its Common Shares, or shall 
reclassify or reorganize its capital structure (except a stock split covered by 
Subsection 3(a) hereof), each Warrant Share shall be replaced for the purposes 
hereof by the securities or properties issuable or distributable in respect of 
one Common Share upon such consolidation, merger, sale, reclassification or 
reorganization, and adequate provisions to that effect shall be made at the time
thereof. Notice of such consolidation, merger, sale, reclassification or 
reorganization, and of said provisions so proposed to be made, shall be mailed 
to the Holder not less than 15 days prior to such event.

        (c) If the Company shall sell all or substantially all of its assets, 
other than as part of a reorganization to which the Company is a party within 
the meaning of the Internal Revenue Code of 1986, as presently in effect, or 
shall distribute its assets in dissolution or liquidation (other than as part of
such a reorganization), the Company shall mail notice thereof to the Holder and 
shall make no distribution to shareholders until the expiration of 15 days from 
the date of mailing of said notice and then only to shareholders

                                       3
<PAGE>
 
of record as of a date at least 15 days after the date of mailing of said 
notice.

        (d) If the Board of Directors of the Company shall declare any dividend 
or other distribution in cash with respect to the Common Shares, other than out 
of surplus, the Company shall mail notice thereof to the Holder not less than 15
days prior to the record date fixed for determining shareholders entitled to 
participate in such dividend or other distribution.

     4. FULLY PAID SHARES; TAXES. The Company agrees that the Common Shares 
        ------------------------
represented by each and every certificate for Warrant Shares delivered on the 
exercise of this Warrant shall, at the time of such delivery, be validly issued 
and outstanding, fully paid and non-assessable, and the Company will take all 
such actions as may be necessary to assure that the par value or stated value, 
if any, per Warrant Share is at all times equal to or less than the then Per 
Share Warrant Price. The Company further covenants and agrees that it will pay, 
when due and payable, any and all Federal and state stamp, original issue or 
similar taxes which may be payable in respect of the issue of any Warrant Share 
or certificate therefor.

     5. LOSS, ETC. OF WARRANT. Upon receipt of evidence satisfactory to the 
        ---------------------
Company of the loss, theft, destruction or mutilation of this Warrant, and of 
indemnify reasonably satisfactory to the Company, if lost, stolen or destroyed, 
and upon surrender and cancellation of this Warrant, if mutilated, and upon 
reimbursement of the Company's reasonably incidental expenses, the Company shall
execute and deliver to the Holder a new Warrant of like date, tenor and 
denomination.

     6. WARRANT HOLDER NOT SHAREHOLDER. Except as otherwise provided therein,
        ------------------------------
this Warrant does not confer upon the Holder any right to vote or to consent or 
to receive notice as a shareholder of the Company, as such, in respect of any 
matters whatsoever, or any other rights or liabilities as a shareholder, prior 
to the exercise hereof.

     7. COMMUNICATION. No notice or other communication under this Warrant

      Re: Saf T Lok Incorporated $3,000,000 Regulation S Offering

Dear Frank:

  I received your letters concerning the escrow arrangements for the $3,000,000
offering to your clients under Regulation S.  The purpose of this letter is to
clarify the terms of the transaction.

  Assuming that the Board of Directors of Saf T Lok Incorporated ("Saf T Lok")
is satisfied with its background check of A.B. & Associates, Inc., and assuming
that the Placement Agent fee is reduced to 13.5%, and assuming that your clients
understand that there is a risk that Nasdaq will delist Saf T Lok based on the
terms of this transaction, Saf T Lok agrees to the following:

  1.  A closing will take place today, November 10, 1997, or as soon as
possible thereafter for $2,500,000 with the number of shares and the stock
purchase warrants reduced proportionately from the $3,000,000 transaction.

  2.  $500,000 in cash from the investors will be held in escrow along with
stock certificates for a total of 250,000 shares and stock purchase warrants for
a total of 416,667 shares until the close of business on December 1, 1997.

  3.  If the investors and Saf T Lok agree that as of the close of business on
December 1, 1997, Saf T Lok is in compliance with all applicable regulatory
requirements, the Escrow 
<PAGE>
 
Frank R. Cohen, Esp.

November 10, 1997


Agent will release the $500,00 to Saf T Lok and deliver the stock certificates
for 250,000 shares and the stock purchase warrants of 416,667 shares to the
investors.

  If, as of the close of business on December 1, 1997, Saf T Lok and the
investors determine that Saf T Lok is not in compliance with all applicable
regulatory requirements, the Escrow Agent shall return the $500,000 to the
investors and return the stock certificates for 250,000 shares and the stock
purchase warrants for 416,667 shares to Saf T Lok.

  4.  If Saf T Lok does not receive the $500,000 from escrow, Saf T Lok shall
not be required to pay the second $375,000 to Marketing Direct Concepts, Inc.
unless and until $1,500,000 of stock purchase warrants have been exercised.

  5.  Saf T Lok has received the letters from the attorneys for each of the
investors as previously requested.

  Please advise me by fax whether or not your clients agree to the above closing
requirements.


                                       Very truly yours,

                                       /s/ William A. Grimm
