         This Settlement Agreement (the "Agreement") entered into as of the last
date written below by and between Big Sky Laser Technologies, Inc. ("BSLT"), a
Montana Corporation with its principal place of business at 601 Haggarty Lane,
Bozeman, Montana, and Premier Laser Systems, Inc. ("PLSI"), a California
corporation, having its principal place of business at 3 Morgan, Irvine,
California

                                   WITNESSETH:

         WHEREAS, PLSI entered into various agreements with BSLT to purchase OEM
laser components (the "Goods") from BSLT destined to be integrated into dental
lasers produced by PLSI;

         WHEREAS, pursuant to such agreements, PLSI has not yet paid for all of
the Goods manufactured by, or manufactured and shipped to PLSI by, BSLT within
the time agreed previously by the parties; and

         WHEREAS, PLSI and BSLT wish to agree upon a payment mechanism that
would permit PLSI to pay for the Goods and to settle the difference among
themselves over the payment for the Goods in order to avoid further discussions,
potential litigation, and the additional expense of further time and money by
the parties to resolve these issues;

         NOW, THEREFORE, in consideration of the mutual promises contained
herein, IT IS HEREBY AGREED:


         1. LIQUIDATION OF DEBT. The parties hereby agree that, as of the date
of this Agreement, the total amount due and owing by PLSI to BSLT in connection
with the purchase of the Goods is the sum of Five Hundred Ninety-One Thousand
Nine Hundred Sixteen and 6/100 Dollars ($591,916.06) (hereafter the "Liquidated
Debt"). This sum may not be reduced by any claim for reduction or set-off that
PLSI may have had, has now, or will have against BSLT other than as set forth
herein; and PLSI agrees to pay this sum to BSLT pursuant to, and only pursuant
to, the terms and conditions set forth in this Agreement

         2. ISSUANCE OF CONVERTIBLE DEBENTURES.

                  2.1.     AMOUNT OF DEBENTURES ISSUED. Simultaneously with the
                           execution of this Agreement, PLSI shall issue to BSLT
                           a series of six debentures (the "Debentures") as
                           follows: five debentures in the amount of One Hundred
                           Thousand Dollars and 00/100 U.S. Dollars (US$

                           Ninety-One Thousand Nine Hundred Sixteen and 06/100
                           U.S. Dollars (US$ 91,916.00) each in the form set
                           forth in Exhibit A.




                           The Debentures shall be convertible into the Common
                           Stock of PLSI (the "Underlying Shares" or "Shares")
                           pursuant to the terms and conditions set forth in the
                           Debentures. Following the issuance of the Debentures,
                           the Debentures shall thereafter represent the
                           Liquidated Debt, and thereafter there shall be no
                           independent debt from PLSI to BSLT with respect to
                           the payment of the purchase price of the Goods.

                  2.2.     REGISTRATION OF THE DEBENTURES. Within five (5)

                           issuance of the Debentures (or in the case of
                           issuance of New Debentures as provided in
                           subparagraph 2.3 below, within five (5) days of the
                           issuance of the New Debentures), PLSI agrees to file

                           the Underlying Shares under the Act, and to
                           thereafter prosecute such application in good faith
                           and with its best efforts. A copy of all filings by
                           PLSI with respect to the Underlying Shares shall be
                           provided to BSLT by the notice procedures set forth
                           in subparagraph 10.1 below within two (2) Business
                           Days on which the filing was made with the SEC. In
                           addition, Notice of the effectiveness of such
                           registration shall be given by PLSI to BSLT within
                           two (2) Business Days of the effectiveness of such
                           Registration.

                  2.3.     APPLICABLE PROCEDURES IF LIQUIDATED DEBT IS NOT
                           SATISFIED. If, after the conversion of all the
                           Debentures and sale of all the Underlying Shares, the
                           Liquidated Debt, as reduced by the price received by
                           BSLT from the sale of the Underlying Shares and any
                           cash payments made by PLSI to BSLT in lieu of
                           conversion or under the terms of the Debentures, is
                           not reduced to an amount less than $50,000 (Fifty
                           Thousand Dollars), BSLT shall have the option, at its
                           sole discretion and after Notice as provided in
                           subparagraph 10.1 below, (a) to require PLSI to issue
                           immediately new Debentures (in the form of the
                           Debenture attached as Exhibit A) to satisfy the
                           remainder of the Liquidated Debt, (b) to pay
                           immediately in cash to BSLT the remainder of the
                           Liquidated Debt, or (c) both to issue immediately new
                           Debentures (the "New Debentures") and to pay
                           immediately in cash the Liquidated Debt, with the
                           amounts to be allocated between the new Debentures
                           and cash payments in a proportion determined at the
                           sole discretion of BSLT and as set forth in the
                           Notice. The procedure set forth in this subparagraph
                           2.3 may be repeated as many times as necessary until
                           the Liquidated Debt has been satisfied or paid in
                           full. For purposes of computing whether or not the
                           Liquidated Debt has been satisfied through the sale
                           of the Debentures, any sales of the Underlying Shares
                           more than two (2) trading days after the conversion
                           of such Underlying Shares (other than sales that were
                           made later than such period because of causes beyond
                           BSLT's control) shall be deemed to have been made at
                           the higher of (a) the closing price of the Underlying
                           Shares two (2) days after conversion or (b) the
                           actual sale price of the Underlying Shares.

                  2.4.     ABSENCE OF RESTRICTIONS ON THE NEW DEBENTURES.
                           Underlying Shares obtained by BSLT as a result of the
                           conversion of New Debentures shall not be subject to
                           the limitation set forth in paragraph 3 below.

         3. LIMITATION ON SALE OF SHARES Commencing on the effective date of the
registration of the Underlying Shares, BSLT agrees that it will not sell on any
public exchange an amount of the Underlying Shares for a sales price in excess
of Two Hundred Thousand U.S. Dollars (US$ 200,000) in any calendar month, except
as provided in subparagraph 2.4 above. For purpose of this paragraph 3, the
value of Shares sold in any calendar month shall be calculated by multiplying
the number of Shares sold during such month times the sale price of one share in
the last sale of the Shares by BSLT during that calendar month.

         4. MANDATORY CONVERSION. PLSI shall have the option, but not the
obligation, to require BSLI, upon five (5) business days notice, to convert any
or all of the Debentures, provided that

                  4.1.     The Underlying Shares are covered by a registration
                           statement freely permitting BSLI to sell the
                           Underlying Shares on a public market;

                  4.2.     The Underlying Shares shall not have been delisted
                           from NASDAQ or any other securities exchange;

                  4.3.     The Underlying Shares, at the time of conversion,
                           shall have a bid value no less than $1.50;

                  4.4.     The conversion of the Debentures will not result in
                           BSLI having sold more than $200,000 of the Underlying
                           Shares in any calendar month;

                           its Articles, By-Laws, and any other understandings
                           among its shareholders, officers and directors in

                           Convertible Debentures as provided herein.

                  7.3.     BREACH OF OTHER AGREEMENTS. Entry by PLSI into this
                           Agreement and issuance by PLSI of the Convertible
                           Debentures as provided herein will not breach any
                           rights of any third parties by law or agreement and
                           will not breach any understandings or agreements,
                           whether oral or written, by and among PLSI, its
                           parents, subsidiaries, affiliates and any third
                           parties.

                  7.4.     ABSENCE OF UNDISCLOSED LIABILITIES. PLSI does not
                           have any material liability, claim or obligation of
                           any nature (whether accrued contingent or otherwise)
                           which (a) as of the date of the latest PLSI financial
                           statements, is not disclosed or reserved for in the
                           latest PLSI financial statements and which is
                           required to be disclosed or reserved for in
                           accordance with accounting principles applied by PLSI
                           on a consistent basis in past years or (b) arose
                           after the date of latest PLSI financial statements
                           other than in the ordinary course of business.

                  7.5.     FRAUDULENT CONVEYANCE. PLSI represents and warrants
                           that neither the issuance of the Debentures to BSLT
                           nor the payment of any sums to BSLT is now, or will
                           be in the future, a fraudulent conveyance as defined
                           by applicable law and that neither the transfer of
                           the Debentures nor the payment of any sums to BSLT
                           will otherwise give rise to a claim by any other of
                           the creditors of PSLI or affiliated entities to set
                           aside and/or recover the Debentures or payments to
                           BSLT to the benefit of such creditors.

                  7.6.     COMPLIANCE WITH THE ACT. PLSI has been, is now, and
                           will continue to remain in compliance with the Act in
                           connection with the issuance of the Debentures and
                           all other actions required to be taken by it under
                           this Agreement. PLSI does not know of any fact or
                           condition that has not already been reported to
                           the Commission in its public filings and that would
                           have any bearing upon the ability of PLSI to register
                           Underlying Shares under the Act.

                  7.7.     OPINION OF COUNSEL. Simultaneously with the execution
                           of this Settlement Agreement, Rutan and Tucker will
                           provide its legal opinion, which shall be binding on
                           Rutan and Tucker as to BSLT, that the representations
                           and warranties of PSLI as set forth in sections 7.1
                           and 7.2 above, to the best of its knowledge, after
                           the exercise of due diligence, are true, accurate and
                           are not rendered misleading by the omission of PLSI
                           to disclose any additional material fact to BSLT in
                           connection with said warranties and representations
                           and that said Debentures are exempt from registration
                           under the Act.

         8. REPRESENTATIONS AND WARRANTIES OF BSLT. BSLT hereby represents and
warrants to PLSI as follows:

                  8.1.     CORPORATE QUALIFICATIONS. BSLT is a Delaware
                           corporation in good standing, is qualified to do
                           business in the State of California, and is subject
                           to no legal disability which would prevent it from
                           entering into this Agreement

                  8.2.     CORPORATE APPROVALS. BSLT has taken all steps
                           necessary to receive, and has received, all approvals
                           of shareholders, officers and directors required by
                           its Articles, By-Laws, and any other understandings
                           among its shareholders, officers and directors in
                           order to enter into this Agreement.

                  8.3.     BREACH OF OTHER AGREEMENTS. Entry by BSLT into this
                           Agreement will not breach any rights of any third
                           parties by law or agreement and will not breach any
                           understandings or agreements, whether oral or
                           written, by and among BSLT, its parents,
                           subsidiaries, affiliates and any third parties.

                  8.4.     KNOWLEGE OF, AND CAPACITY TO ASSUME, ECONOMIC RISK.
                           BSLT acknowledges and represents that:

                           8.4.1.   BSLT is an "accredited investor" as defined
                                    in 17 U.S.Css.230.501(a);

                           8.4.2.   BSLT has reviewed the annual report on form
                                    10-K/A for the fiscal year ended March 31,
                                    1999, and the quarterly report on form 10-Q
                                    for the quarter ended June 30, 1999;

                           8.4.3.   BSLT is in a financial position to hold the
                                    Shares for an indefinite period of time, is
                                    able to bear the economic risk of an
                                    investment in the Shares and is able to
                                    withstand a complete loss of its investment
                                    in the Shares;

                           8.4.4.   BSLT has the knowledge and experience in
                                    business and financial matters that make it
                                    capable of evaluating the merits and risks
                                    of an investment in the Shares;

                                        6


                           8.4.5.   BSLT understands that an investment in the
                                    Shares is highly speculative and involves a
                                    high degree of risk but believes that an
                                    investment in the Shares is suitable based
                                    upon its investment objectives and financial
                                    needs, and that it has adequate means to
                                    undertake the risk and for providing for its
                                    current financial needs and has no need for
                                    liquidity of investment with respect to the
                                    Shares;

                           8.4.6.   BSLT has been given access to full and
                                    complete information regarding PLSI and has
                                    utilized that access to its satisfaction for
                                    the purpose of obtaining information
                                    concerning PLSI, an investment in the Shares
                                    and the terms and conditions of this
                                    offering of the Shares, and has had the
                                    opportunity to ask questions of, and receive
                                    answers from, representatives of PLSI, for
                                    the purpose of obtaining any additional
                                    information to the extent reasonably
                                    available that is necessary to verify the
                                    information provided;

                           8.4.7.   BSLT recognizes that an investment in the
                                    Shares involves significant risks, including
                                    but not limited to, the risk of economic
                                    loss from the operations of PLSI due to the
                                    limited operating history of PLSI and the
                                    risk of economic loss from the operations of
                                    PLSI;

                           8.4.8.   BSLT understands that the Shares may be sold
                                    only (i) upon registration of the Shares
                                    pursuant to the Securities Act of 1933 (the
                                    "Act") or (ii) in a transaction either (a)
                                    not subject to the Act or (b) in compliance
                                    with the terms and conditions of an
                                    exemption from the Act.

                           (iv) upon actual receipt by the party to whom such
                           notice is required to be given.

                  10.2.    ASSIGNMENT. This Agreement may not be assigned in
                           whole or part by either party without the prior
                           written approval by the other party; provided that
                           the Agreement may be assigned, in the case of
                           corporate reorganization, to an entity controlled by
                           the assigning party or under common control with the
                           assigning party.

                  10.3.    ENTIRE AGREEMENT. This Agreement constitutes the
                           entire agreement among the parties and is intended
                           expressly to supercede the letter agreement signed by
                           the parties on September 1, 1999. In addition, this
                           Agreement may not be modified except by a subsequent
                           writing duly executed by all parties.

                  10.4.    GOVERNING LAW. The internal law, without regard to
                           conflicts of laws principles, of the State of
                           California will govern all questions concerning the
                           construction, validity and interpretation of this
                           Agreement and the performance of the obligations
                           imposed by this Agreement.

                  10.5.    VENUE AND JURISDICTION. All actions brought against
                           PLSI under this Agreement, including any of the
                           actions set forth in paragraph 6 above, may be
                           brought in the state or federal courts located in the
                           State of Montana. PLSI hereby irrevocably waives
                           personal service of process and consents to process
                           being served in any such suit, action or proceeding
                           by receiving a copy thereof sent to PLSI at the
                           address in effect for notices to it in subparagraph
                           10.1 above and agrees that such service shall
                           constitute good and sufficient service of process and
                           notice thereof. Nothing contained herein shall be
                           deemed to limit in any way any right by BSLT to serve
                           process in any manner permitted by law.

                  10.6.    COUNTERPARTS. This Agreement may be executed in
                           counterparts with any two counterparts signed by each
                           party having the full force, effect and authority of
                           an original document signed by all parties.

                  10.7.    NO WAIVER. No failure or delay by any party in the
                           exercise of any of its rights hereunder will be
                           deemed to be a waiver of any of its rights.

                                        9


                  10.8.    SEVERANCE. In the event that any provision or
                           provisions are found by any tribunal of competent
                           jurisdiction to be null or void, such provisions will
                           be deemed to be severed from this Agreement and the
                           remainder of the Agreement will remain in full force
                           and effect.

                  10.9.    HEADINGS. The headings contained in this Agreement
                           are for reference only and shall not be used to
                           resolve any questions of interpretation or
                           construction.

                  10.10.   RULES OF CONSTRUCTION. All parties have entered into
                           this Agreement upon the advice of counsel and with
                           full participation in the drafting of this Agreement.
                           Accordingly, the parties agree that the principle
                           that would construe a contract strictly against the
                           party who drafted such contract shall have no
                           application to this Agreement.

         IN WITNESS WHEREOF, the undersigned officers of the party, having been
duly authorized to bind their respective parties, have executed this Agreement
on behalf of their respective parties as of the date last below written.
