Attn:  E. Wyatt Cannady

Gentlemen:

     In connection with the offer and proposed issuance of up to $3,000,000 in
Common Stock and options to purchase Common Stock (the "OFFERING") by Ion Laser
Technology, Inc., a Utah corporation ("ILT" or the "COMPANY"), in reliance on

1933, as amended (the "ACT"), and similar provisions of state law, the
undersigned purchasers (collectively, the "PURCHASERS") and the Company hereby
agree as follows:


                                    Page 19 of 73
<PAGE>

          1.   PURCHASE OF SECURITIES.  Subject to the terms and conditions 
of this Agreement, each of the Purchasers hereby agrees to acquire, and the 
Company agrees to sell, the following securities (collectively the "PURCHASED 
SECURITIES"):

          1.1  COMMON STOCK.  Each of the Purchasers shall purchase and the
     Company shall sell to each such Purchaser that number of shares of the
     Company's Common Stock, par value $.001 per share (the "COMMON SHARES"),
     set forth opposite such Purchaser's name on SCHEDULE I to this Agreement. 
     The consideration for the issuance of the Common Shares shall be $7.00 per
     share.  The total purchase price (the "PURCHASE  PRICE") for the 428,572
     shares of Common Stock being purchased hereunder shall be Three Million
     Dollars ($3,000,000).  Each Purchaser shall pay his or its portion of the
     Purchase Price in full at Closing, as hereinafter defined, via wire
     transfer to the Company on or before the Closing Date, as that term is
     defined in Section 5 of this Agreement.  Wire instructions shall be
     provided to Purchasers by the Company prior to the Closing.

          1.2  OPTIONS TO ACQUIRE COMMON STOCK.  As additional consideration for
     the Purchase Price, the Company shall grant to each of the Purchasers, in
     addition to the Common Shares, options to purchase up to that number of
     shares of Common Stock set forth opposite such Purchaser's name on
     SCHEDULE I hereto over a ten-year period at a price of $9.00 per share (the
     "NEW OPTIONS").  The rights of each Purchaser to acquire Common Stock under
     the New Options shall be as set forth in written option agreements in the
     form attached to this Agreement as EXHIBIT A (the "NEW OPTION AGREEMENTS")
     and by this reference made a part hereof.

     2.   AMENDMENT OF OLD OPTIONS.  The Company hereby agrees to amend that
certain Option Agreement No. 001 dated April 1, 1996 issued to LCO Investments
Limited, relating to 773,334 shares of Common Stock, and that certain Option
Agreement No. 002 dated April 1, 1996 issued to Richard S. Braddock
("BRADDOCK"), relating to 193,333 shares of Common Stock (together the "OLD
OPTIONS"), such that: (i)  the purchase price of the shares underlying the Old
Options shall be changed from $20.00 per share to $9.00 per share, and (ii) any
provisions in the Old Options, or in the original Securities Purchase Agreement
dated April 1, 1996 between the Company and the Purchasers, purporting to
restrict by contractual agreement the resale of shares of Common Stock
underlying the Old Options for a period of two years from April 1, 1996, shall
be deleted.  The amendments to the Old Options shall be in the form set forth in
EXHIBIT B (the "AMENDED OPTION AGREEMENTS") and by this reference made a part
hereof.

     3.   DELIVERY OF SHARE CERTIFICATES AND OPTION AGREEMENTS.  At the Closing,
the Company shall deliver to Purchasers certificates representing the Common
Shares, which 


                                    Page 20 of 73
<PAGE>

shall be fully paid and nonassessable upon issuance, as well as the New Option
Agreements and the Amended Option Agreements.  The Common Shares and the New
Options shall be issued in increments and in the names of the Purchasers as set
forth in SCHEDULE I hereto.

     4.   REGISTRATION RIGHTS AND EXCHANGE FILINGS.  The Common Shares and the
shares of Common Stock underlying the exercise of the New Options shall be
subject to certain registration rights, as provided in that certain Registration
Rights Agreement attached hereto as EXHIBIT C and by reference made a part
hereof.  (Such Registration Rights Agreement, together with this Securities
Purchase Agreement, the New Option Agreements, and the Amended Option
Agreements, constitute the "TRANSACTION DOCUMENTS").  In addition, ILT shall
make appropriate filings under the rules of the American Stock Exchange ("AMEX")
in order that the Common Shares and the shares of Common Stock underlying the
New Options will be included in the Company's listing with the AMEX.

     5.   CLOSING.  Payment of the Purchase Price by the Purchasers and delivery
of the Common Shares and the fully executed New Option Agreements and Amended
Option Agreements by ILT shall be deemed to be the completion of the
transactions contemplated by this Agreement ("CLOSING").  Closing shall occur
concurrently with the execution of this Agreement (the "CLOSING DATE"), or such
later date as the parties may hereafter agree in writing (the "CLOSING DATE").

     6.   FAILURE OF ANY PURCHASER TO CLOSE.  The Company shall not be obligated
to issue and sell any of the Purchased Securities unless all 428,572 of the
Common Shares and all of the New Options to be purchased and sold hereunder are
purchased by the Purchasers.  In the event any Purchaser fails to purchase at
the Closing any of the Common Shares and New Options scheduled to be purchased
by him or it, the other Purchasers shall have the right to purchase at the
Closing (or on such other date as the Company and such Purchaser(s) shall agree)
the Common Shares and New Options that are not so purchased, and the Company
shall issue and sell such Common Shares and New Options to such other
Purchaser(s).


     7.   USE AND DISPOSITION OF PROCEEDS.  The gross proceeds of this
transaction will be Three Million Dollars ($3,000,000).  The Company intends to
use the proceeds as follows:

   Application of Proceeds                Dollar Amount       Percentage
   -----------------------                -------------       ----------

   Promote BriteSMILE products           $ 1,500,000             50%
   Equipment and improvements                300,000             10%
   Research and development                  500,000             17%
   Working capital and payment of 
   offering expenses                         700,000             23%
                                         -----------            ----
                            Total        $ 3,000,000            100%

The foregoing represents the Company's present intention and best estimates with
respect to the use of the offering proceeds.  Pending use of the net proceeds
for the above purposes, the Company intends to invest the funds in certificates
of deposit or other fully-insured investment grade securities.  Any funds
received from the exercise of the New Options will be added to working capital. 
Purchasers acknowledge and agree that the Company shall have immediate access to
such funds, according to the Company's management's discretion, following the
Closing and delivery of the Common Shares and the New Options to Purchasers.

     8.   SPECIAL COVENANTS.

          8.1  FINANCIAL REPORTS.  While any of the New Options remain
     outstanding and unexercised, ILT shall provide Purchasers with copies of
     its annual report to shareholders, annual report on Form 10-KSB (or such
     other form as ILT may be qualified to use for such purpose), quarterly
     reports on Form 10-QSB (or such other form as may properly be available to
     ILT for such reports), any report on Form 8-K, and internally prepared
     (unaudited) financial statements, to the extent prepared by ILT.  In the
     case of the reports described above which are filed with the Securities and
     Exchange Commission, copies of the same will be provided to Purchasers
     within five (5) working days of filing with the Commission.  In the case of
     the other documents, to the extent the same are prepared by ILT, they shall
     be provided on or before the 20th day following the month then ended.

          8.2  At the Closing, or as soon thereafter as practical (but in no
     event later than May 7, 1997), the Company shall deliver to Purchasers a
     Cashflow Analysis, including estimations of the rate at which the proceeds
     of this Offering will be used by the Company.

     9.   REPRESENTATIONS AND WARRANTIES OF PURCHASERS.  To induce the Company's
acceptance of this Agreement, each Purchaser hereby represents and warrants,
severally as to itself or himself and not jointly, to the Company and its agents
and attorneys as follows:

             with his/her spouse, as of the date hereof, exceeds $1,000,000.

             the Securities Exchange Act of 1934.
                                                                 ______(Initial)

                                    Page 23 of 73
<PAGE>

               (2)  Purchaser is not a "U.S. Person" as defined under Regulation
     S because (mark and complete each applicable item):

                    (a)  Purchaser is a corporation organized under the laws of
               __________________, which is outside the United States and is not
               a territory or possession of the United States and in addition to
               the foregoing, Purchaser was not formed by a U.S. Person for the
               purpose of investment in securities not registered under the Act
               and Purchaser will not purchase the Purchased Securities on
               behalf of a U.S. Person as defined by the Act.;
                                                                 ______(Initial)

                    (b)  Purchaser is a natural person resident in
               ________________ and a citizen of _____________________.
______________________________________________________________________ (Initial)

          9.2   LIQUIDITY.  Purchaser presently has sufficient liquid assets to
     pay that portion of the Purchase Price to be paid by such Purchaser
     hereunder.  Purchaser's overall commitments to investments that are not
     readily marketable is not disproportionate to Purchaser's total assets, and
     Purchaser's investment in the Company will not cause such overall
     commitment to become excessive.  Purchaser has adequate means of providing
     for its current needs and contingencies and has no need for liquidity in
     its investment in the Company or for a source of income from the Company. 
     Purchaser is capable of bearing the economic risk and the burden of the
     investment contemplated by this Agreement, including, but not limited to,
     the possibility of the complete loss of the value of the Purchased
     Securities and the limited transferability of the Purchased Securities,
     which may make the liquidation of the Purchased Securities impossible in
     the near future.

          9.3   ORGANIZATION, STANDING, AUTHORIZATION.  If not an individual,
     Purchaser is duly organized, validly existing, and in good standing under
     the laws of the country of organization described in SCHEDULE I hereto and
     has the requisite power and authority to enter into this Agreement, acquire
     the Purchased Securities and execute and deliver any documents or
     instruments in connection with this Agreement.  The execution and delivery
     of this Agreement, and all other documents and instruments executed by
     Purchaser in connection with any of the transactions contemplated by this
     Agreement have been duly authorized by all required action of Purchaser's
     members or managers.  The person executing, on Purchaser's behalf, this
     Agreement and any other documents or instruments executed by Purchaser in
     connection with this Agreement is duly authorized to do so.

<PAGE>

          9.4  ABSENCE OF CONFLICTS.  Purchaser represents and warrants that the
     execution and delivery of this Agreement and any other document or
     instrument executed in connection with this Agreement, and the consummation
     of the transactions contemplated thereby, and compliance with the
     requirements thereof, will not violate any law, rule, regulation, order,
     writ, judgment, injunction, decree or award binding on Purchaser, or the
     provision of any indenture, instrument or agreement to which  Purchaser is
     a party or is subject, or by which Purchaser or any of their properties is
     bound, or conflict with or constitute a material default thereunder, or
     result in the creation or imposition of any lien pursuant to the terms of
     any such indenture, instrument or agreement, or constitute a breach of any
     fiduciary duty owed by such Purchaser to any third party, or require the
     approval of any third-party pursuant to any material contract, agreement,
     instrument, relationship or legal obligation to which Purchaser are subject
     or to which any of their properties, operations or management may be
     subject.

          9.5  SOLE PARTY IN INTEREST.  Purchaser represents that it is the sole
     and true party in interest, and no other person or entity has or will have
     upon the issuance of the Purchased Securities any beneficial ownership
     interest in the Purchased Securities or any portion of the Purchased
     Securities, whether direct or indirect, other than the equity holders or
     beneficiaries of such Purchaser.

          9.6  INVESTMENT PURPOSE.  Purchaser represents that it is acquiring
     the Purchased Securities for its own account and for investment purposes
     and not on behalf of any other person or entity or for or with a view to
     resale or distribution.

          9.7  KNOWLEDGE AND EXPERIENCE.  Purchaser is experienced in evaluating
     and making speculative investments, and has the capacity to protect
     Purchaser's interests in connection with the acquisition of the Purchased
     Securities.  Purchaser has such knowledge and experience in financial and
     business matters in general, and investments in the laser industry in
     particular, that Purchaser is capable, on Purchaser's behalf, of evaluating
     the merits and risks of Purchaser's investment in the Company.  Purchaser
     has been informed that an investment in the Company is speculative and has
     concluded that Purchaser's proposed investment is appropriate in light of
     its overall investment objectives and financial situation.

          9.8  INVESTMENT ADVISORS.  No party has received or will receive any
     compensation or other remuneration for advising Purchaser with respect to
     this investment, and Purchaser represents that no investment advisor or
     purchaser representative has been consulted or retained in connection with
     Purchaser's decision to invest in the Company.

          9.9  DISCLOSURE, ACCESS TO INFORMATION.  Purchaser confirms that it
     has received and thoroughly read and is familiar with and understands this
     Agreement, and that all documents, records, books and other information
     pertaining to Purchaser's investment in the Company requested by Purchaser
     have been made available for inspection and copying and that there are no
     additional materials or documents that have been requested by Purchaser
     that have not been made available by the Company.  Purchaser further
     acknowledges that on behalf of the Purchasers and as Purchasers
     representatives, since May 2, 1996, Braddock and Andrew Hofmeister have
     served as members of the Board of Directors of the Company.  Purchaser
     further acknowledges that the Company is subject to the periodic reporting
     requirements of the Securities Exchange Act of 1934, as amended (the
     "EXCHANGE ACT"), and Purchaser has reviewed or received copies of any such
     reports that have been requested by it.  Without limiting the generality of
     the foregoing, Purchaser acknowledges that it has received and has reviewed
     copies of the following documents and materials, all of which are
     incorporated herein by reference:

              (1)  Articles of Incorporation of the Company, as amended;

              (2)  Bylaws of the Company, as amended;

              (3)  Asset Purchase Agreement with Brite Smile, Inc., dated as of
                   February 6, 1996;

              (4)  Annual Report on Form 10-KSB for the fiscal year ended March
                   31, 1995 and 1996;

              (5)  Quarterly Reports on Form 10-QSB for the quarters ended June
                   30, September 30, and December 31, 1995 and 1996;


          9.10  EXCLUSIVE RELIANCE ON THIS AGREEMENT.  In making the decision to
     purchase the Purchased Securities, Purchaser has relied exclusively upon
     information included in this Agreement or incorporated herein by reference
     pursuant to Section 9.9, and not on any other representations, promises or
     information, whether written or verbal, by any person.

          9.11  ACCURACY OF UNINCORPORATED DOCUMENTS AND OTHER UNINCORPORATED
     MATERIALS.  To the extent Purchaser has received documents or other
     materials, other than as expressly incorporated herein by reference
     pursuant to Section 9.9, and subject to Section 9.15 of this Agreement,
     Purchaser acknowledges the following with respect to such documents and
     materials:


                                    Page 26 of 73
<PAGE>

               (1)  Such documents and materials and any projections contained
          therein may be incomplete, may contain errors or misstatements, and do
          not purport to adequately describe the transactions contemplated by
          this Agreement or the status of the development of the Company's
          technology.  Purchaser agrees that such documents and materials cannot
          be relied upon in making a decision as to whether to purchase the
          Purchased Securities and acknowledges that there can be no assurance
          that any of the projections contained therein will be accomplished by
          the Company; and

               (2)  Purchaser has been advised and fully understands that any
          summaries, projections, forecasts or estimates included in such
          documents and materials, including those relating to product
          development schedules and projections, possible revenues, income,
          profitability of the Company or an investment therein inherently
          involve uncertainties and may be affected by circumstances in the
          future which cannot be reasonably predicted and are beyond the control
          of the Company.  Further, the projections, forecasts and estimates are
          speculative and may be optimistic, and there can be no assurance that
          any of the projections, forecasts or estimates will be reached, or
          that the Company will successfully produce a commercially viable
          product or that the Company will realize any income or profits or that
          any dividends or distributions of profits will be paid on the
          Company's securities.  The use of the words "believes," "estimates,"
          "anticipates" and similar expressions are intended to identify
          forward-looking statements, all of which are subject to certain risks
          and uncertainties that could cause actual results to differ materially
          from those projected.  Purchaser should not place undue reliance on
          such forward-looking statements, which speak only as of the date(s)
          made.  The Company undertakes no obligation to publicly release the
          result of any revisions to these forward-looking statements that may
          be made to reflect events or circumstances after the date hereof or to
          reflect the occurrence of unanticipated events.

          9.12  RESIDENCY.  Each Purchaser has its principal place of business 
     as set forth in SCHEDULE I hereto.

          9.13  ADVICE OF COUNSEL.  Purchaser understands the terms and
     conditions of this Agreement, has investigated all issues to Purchaser's
     satisfaction, has consulted with such of Purchaser's own legal counsel or
     other advisors as Purchaser deems necessary, and is not relying, and has
     not relied on the Company for an explanation of the terms or conditions of
     this Agreement or any document or instrument related to the transactions
     contemplated thereby.  Purchaser further acknowledges, understands and
     agrees that, in arranging for the 


                                    Page 27 of 73
<PAGE>

     preparation of this Agreement and all other documents and materials related
     thereto, the Company has not attempted to procure, and has not procured,
     legal representation for Purchaser.

          9.14 ACCURACY OF REPRESENTATIONS AND INFORMATION.  All representations
     made by Purchaser in this Agreement and all documents and instruments
     related to this Agreement, and all information provided by Purchaser to the
     Company concerning Purchaser and its financial position is correct and
     complete in all material respects as of the date hereof.  If there is any
     material change in such information before the actual issuance of the
     Purchased Securities, Purchaser immediately will provide such information
     to the Company.

          9.15  NO REPRESENTATIONS.  None of the following have ever been
     represented, guaranteed, or warranted to Purchaser by the Company or any of
     its employees, agents, representatives or affiliates, or any broker or any
     other person, expressly or by implication:

                    (1)  The approximate or exact length of time that Purchaser
          will be required to remain as owner of the Purchased Securities;

                    (2)  The percentage of profit or amount of or type of
          consideration, profit or loss (including tax write-offs or other
          tax benefits) to be realized, if any, as a result of an
          investment in the Purchased Securities; or

                    (3)  The past performance or experience on the part of the
          Company or any affiliate or their associates, agents or
          employees, or of any other person as being indicative of future
          results of an investment in the Purchased Securities.

          9.16  FEDERAL TAX MATTERS.  Purchaser has reviewed and understands the
     federal income tax aspects of its purchase of the Purchased Securities, and
     has received such advice in this regard as Purchaser deems necessary from
     qualified sources such as attorneys, tax advisors or accountants, and is
     not relying on any representative or employee of the Company for such
     advice.

          9.17  NO BROKERS OR FINDERS.  Purchaser represents that no third 
     person has in any way brought the parties together or been instrumental
     in the negotiation, execution, or consummation of this Agreement or any
     instrument, document or agreement related to this Agreement, or will
     receive a fee or any 


                                    Page 28 of 73
<PAGE>

     compensation for doing so.  Purchaser agrees to indemnify the Company
     against any claim by any third person for any commission, brokerage fee,
     finders fee, or other payment with respect to this Agreement or the
     transactions contemplated hereby based upon any alleged agreement or
     understanding between such party and such third person, whether expressed
     or implied, arising from the actions of such party.  The covenants set
     forth in this Section 9.17 shall survive the Closing Date and the
     consummation of the transactions contemplated by this Agreement.

     10.  CERTAIN RISK FACTORS.  Purchasers have been informed about and fully
understand that there are risks associated with an investment in the Company. 
Such risks may include, but not necessarily be limited to, the following: 

          10.1  FORWARD LOOKING STATEMENTS.  Statements contained in the
     Company's annual and quarterly reports on Forms 10-KSB and 10-QSB that are
     not purely  historical are forward looking statements within the meaning of
     Section 27A of the Securities Act of 1933 and Section 21E of the Securities
     Exchange Act of 1934.  Such statements include statements regarding the
     Company's expectations, beliefs, hopes, intentions or strategies regarding
     the future.    All forward looking statements included in such reports are
     based on information available to the Company on the date thereof and the
     Company assumes no obligation to update any such statements.  The Company
     cautions that actual results could differ materially from those in such
     forward looking statements.  Among other things, the Company's business and
     its results of operations may be affected by factors which could cause
     actual results to differ materially from those described in the forward
     looking statements contained in the reports.  Such factors include, but are
     not limited to, the following additional risks set forth in this section
     10.

          10.2  GOVERNMENT REGULATION.  The Company's products are subject to 
     the provisions of the Federal Food, Drug and Cosmetic Act (the "ACT") 
     and the Safe Medical Devices Amendment of the Act.  The Act is 
     administered by the Food and Drug Administration ("FDA") and similar 
     laws are administered by similar agencies in other countries.  The Act 
     generally classifies medical devices into categories, and establishes 
     varying degrees of labeling and marketing clearance procedures.  The 
     Company is subject to FDA standards and procedures governing the 
     manufacture of medical devices and to FDA inspection for compliance with 
     such standards.  The Company has obtained FDA clearance for the use of 
     its lasers in the tooth whitening process.  The Company is required to 
     manufacture its regulated products in accordance with Good Manufacturing 
     Procedures ("GMP") and is subject to periodic audits by the FDA.  In 
     addition, the use of the Company's products may be regulated by various 
     state agencies.  Although the Company believes it has been and is now in 
     compliance with the 

                                    Page 29 of 73
<PAGE>

     FDA's rules and GMP, there can be no assurance that the Company's products
     will be able to comply successfully with any such requirements or
     regulations.  Federal and state regulations regarding the manufacture and
     sale of medical devices are subject to future change.  The Company cannot
     predict what material impact, if any, such changes might have on its
     business.  In addition, the introduction of the Company's products in
     foreign markets will require obtaining foreign regulatory clearances. 
     There can be no assurance that the Company will be able to obtain
     regulatory clearances for all of its products in the U.S. or in foreign
     markets.  Although the Company believes that it will continue to be able to
     comply with all applicable regulations of the FDA, including GMP
     guidelines, current regulations depend heavily on administrative
     interpretations, and there can be no assurance that future interpretations
     made by the FDA or other regulatory btive effect, will not adversely affect
     the Company.

          10.3  CERTAIN RESTRICTIONS ON DENTAL TECHNICIANS RELATED TO LASER
     PROCEDURES.  Many dentists who have acquired and who desire to acquire the
     Company's laser tooth whitening system also desire to utilize a dental
     hygienist and/or dental technician to perform many aspects of the laser
     tooth whitening procedure.  The dental licensing boards or similar
     regulatory bodies in several states of the United States have recently
     promulgated or proposed rules which prohibit dental hygienists and/or
     dental technicians from operating or using lasers in connection with dental
     procedures, including tooth whitening procedures.  Dental licensing boards
     or similar regulatory bodies in other states and countries can and may
     adopt similar rules, the effect of which is to discourage some dentists
     from acquiring the Company's laser tooth whitening system because they are
     not able to utilize less expensive employees and staff (dental hygienists
     and/or dental technicians) for a significant portion of the laser tooth
     whitening procedure.  The Company has determined to challenge rules adopted
     by states prohibiting dental hygienists and/or dental technicians from
     operating laser equipment in tooth whitening procedures.  Further, the
     Company has determined to initiate rulemaking procedures in other states
     which would expressly allow dental hygienists, and in some cases, dental
     technicians, to utilize lasers in tooth whitening procedures.  However,
     there can be no assurance that the Company's efforts opposing rules
     prohibiting dental hygienists and/or dental technicians from operating
     lasers in tooth whitening procedures or advancing rules allowing such will
     be successful.  To the extent that state licensing boards or similar
     regulatory bodies in a majority of the states of the United States and/or
     in foreign countries adopt rules prohibiting dental hygienists and/or
     dental technicians from operating lasers in tooth whitening procedures, the
     Company believes that the appeal of its laser tooth whitening products as a
     s dentists engaged in cosmetic dentistry practices will be reduced.


                                    Page 30 of 73
<PAGE>

          10.4  TECHNOLOGICAL OBSOLESCENCE.  The business of designing and
     manufacturing technical products such as lasers is characterized by rapid
     technological change.  In addition, there is increasing competition in the
     creation and manufacture of tooth whitening compounds used in the tooth
     whitening process.   Although the Company has obtained or applied for
     patents on certain aspects of its technology and processes used by it,
     there can be no assurance that the Company's competitors will not develop
     or manufacture products technologically superior to those of the Company. 
     The Company also relies upon trade secrets and no assurance can be given
     that others will not independently develop substantially equivalent
     proprietary information and techniques or otherwise gain access to the
     Company's trade secrets or disclose such technology, or that the Company
     can meaningfully protect its rights to unpatented trade secrets.  The
     Company requires its key employees, consultants and advisors to execute
     confidentiality agreements upon the commencement of an employment or
     consulting relationship with the Company.

          10.5  COMPETITION.  The Company operates in a highly competitive
     industry and competes with firms which may have greater financial
     resources, broader experience and more substantial marketing operations
     than the Company.  Other laser manufacturers have also begun to market and
     use lasers in the tooth whitening process.  Although the Company believes
     its process to be superior to those of its competitors, there can be no
     assurance that the Company will be able to effectively compete with larger,
     better financed companies in the same industry.

          10.6  PRODUCT LIABILITY.  Manufacturers and distributors of products
     used in the medical industry are from time to time subject to lawsuits
     alleging product liability, negligence or related theories of recovery,
     which have become an increasingly frequent risk of doing business in these
     industries.  Although lawsuits may arise or claims may be asserted based on
     product liability or other legal theories against the Company, all such
     actions have been insured against and there are no such actions pending. 
     While the Company does not anticipate any such lawsuits, there can be no
     assurance that the Company will not be subjected to claims for and suffer
     substantial losses arising out of the use of any of its products which may
     be defective.  Such claims and losses, and the expense of defending against
     such claims, would be costly and could have a materially adverse effect on
     the Company's results of operations.  Although the Company presently
     maintains product liability insurance coverage, there can be no assurance
     that such coverage will be available for such risks in the future or that,
     if available, it would prove sufficient to cover potential claims or that
     the present amount of insurance can be maintained in force at an acceptable
     cost.  Furthermore, the assertion of such claims, regardless of their merit
     or eventual 


                                    Page 31 of 73
<PAGE>

     outcome, also may have a material adverse effect on the Company, its
     business reputation and its operations.

          10.7  DEPENDENCE UPON MARKET ACCEPTANCE OF COMPANY'S PRODUCTS.  The
     Company's ability to expand its product line and market its new products
     and processes (including the BriteSmile process) will depend upon the
     willingness of potential customers to purchase the products, in many
     instances to replace products presently purchased from the Company's
     competitors.  In addition, there can be no assurance that any new products
     or technologies developed or acquired by the Company, including those
     currently being developed by the Company, will be accepted by the industry.
     The Company currently has limited marketing capabilities and will need to
     hire additional sales and marketing personnel for the new products.  There
     can be no assurance that any sales and marketing effort undertaken by the
     Company will be successful.  Furthermore, marketing is expensive and
     amounts spent to promote the products and processes of the Company will
     affect its results of operations.

          10.8  DEPENDENCE ON PATENTS AND PROPRIETARY RIGHTS.  The Company has
     several United States patents and has filed additional patent applications
     in the U.S. Patent and Trademark Office.  These patents and pending
     applications relate to the Company's multiplexer, collinated beam delivery
     system for composite curing, laser resonator, krypton or "mixed gas" ion
     laser device, and the BriteSmile process.  The Company believes patents and
     proprietary rights have been and will continue to be important in enabling
     the Company to compete.  However, there can be no assurance that the
     pending patents will issue or, if they do issue, that they and the other
     patents of the Company will not be challenged or circumvented or will
     provide the Company with any competitive advantages or that any patents
     will issue from pending patent applications.  Failure to obtain patents in
     certain foreign countries may materially adversely affect the ability of
     the Company to compete effectively in certain international markets.  The
     Company also relies on trade secrets that it seeks to protect, in part,
     through confidentiality agreements with employees and other parties.  There
     can be no assurance that these agreements will not be breached, that the
     Company would have adequate remedies for any breach or that the Company's
     trade secrets will not otherwise become known to or independently developed
     by competitors.  The Company may become involved from time to time in
     litigation to determine the enforceability, scope and validity of
     proprietary rights.  Any such litigation could result in substantial cost
     to the Company and divert the efforts of its management and technical
     personnel and adversely affect results of operations.

          10.9  RISKS OF FOREIGN SALES; FOREIGN OPERATIONS.  The Company's
     expanded marketing strategy includes increased marketing of its products in


                                    Page 32 of 73
<PAGE>

     foreign countries.  Accordingly, the Company's business is subject to many
     of the risks of international operations, including tariff restrictions,
     foreign currency fluctuations, currency control regulations, competing or
     conflicting manufacturing standards, government regulation and approval
     policies for medical testing and therapy devices and licensing
     requirements.  In addition to the foreign sales activity of the Company,
     since 1989 the Company has been engaged in manufacturing operations in
     Shanghai, China, through its wholly-owned subsidiary, Ion Laser Technology
     Development Company and its ownership in Shanghai Laser Technology Company,
     a Chinese joint venture.  The joint venture manufactures and sells lasers
     to markets in China and other parts of the world.  In recent years, the
     political and economic climate in China has been subject to volatile
     change.  Political and economic changes in the future could adversely
     affect the Company's investment in the joint venture.

          10.10  RECENT NET LOSS; POSSIBLE FUTURE LOSSES.  Although the Company
     realized a modest net profit in its last fiscal year, the Company realized
     net losses in prior years.  The Company's operations continue to use
     significant amounts of cash as the Company endeavors to promote its
     BriteSmile tooth whitening products and services.   Although the Company
     has experienced revenue growth since its inception, there can be no
     assurance that such growth will continue or that net losses will not be
     incurred in future operating periods.

          10.11  BACKLOG; QUALITY ASSURANCE.  The Company has recently increased
     its production capacity and is in the process of adding to that capacity at
     its Salt Lake City facility.  The increased demand for its lasers and for
     the chemical reagents used in the tooth whitening process resulting from
     increased sales activity in this industry has resulted in an increase in
     orders for the Company's products.  Inventories of finished products and
     work in progress have increased substantially.  In the past nine months the
     Company has experienced delays in delivering some finished products to
     customers.  In some cases there have also been an unusually high number of
     warranty claims related to delivered product.  While some quality assurance
     problems may reasonably be expected as a new product line is started or as
     new personnel are hired and trained to meet increasing demand, warranty
     claims are a significant expense to the Company and the delays caused by
     backlogs or by quality assurance problems adversely affect operating
     results.  The Company constantly works to improve quality and to reduce
     backlog, but there can be no assurance that these trends will not continue
     in the foreseeable future.

          10.12 CHANGE IN BUSINESS FOCUS.  The Company is currently
     transitioning its business to rely more heavily on the sale of laser tooth
     whitening chemicals and lasers used in the cosmetic dental market.  In
     addition to the foregoing, 


                                    Page 33 of 73
<PAGE>

     factors that may affect the Company's results of operations include the
     volume and timing of orders received, changes in the mix of product sold,
     market acceptance of the Company's products, competitive pricing pressures,
     the Company's ability to meet increasing demand, the Company's ability to
     introduce new products on a timely basis, the timing of new product
     announcements and introductions by the Company or its competitors, changing
     customer requirements, delays in meeting new product qualifications, the
     time of research and development, and the timing and extent of expenses
     related tosuch research and development.

          10.13  FUTURE CAPITAL REQUIREMENTS.  In the course of expansion, there
     is no guarantee that the Company will be able to raise adequate capital to
     fund subsequent growth, whether via the capital markets, private
     placements, lines of credit or other means.

          10.14  ABSENCE OF DIVIDEND POLICY.  The Company has never declared or
     paid any cash dividends on its shares and does not anticipate paying cash
     dividends in the foreseeable future.

          10.15  IMMEDIATE AND SUBSTANTIAL DILUTION.  The Purchasers will incur
     immediate, substantial dilution of their interests, because the net
     tangible book value per share of the common stock after the offering will
     be substantially less than the price per share paid by the Purchasers.

     11.  MANNER OF SALE.  At no time were Purchasers presented with or
solicited by or through any leaflet, public promotional meeting, television
advertisement or any other form of general solicitation or advertising.

     12.  RESTRICTED SHARES.  Purchasers understand and acknowledge that neither
the Purchased Securities nor the Common Stock underlying the New Options have
been registered under the Act, or any state securities laws, and that they will
be issued in reliance upon certain exemptions from the registration requirements
of those laws, and thus cannot be resold unless they are registered under the
Act or unless the Company has first received an opinion of competent securities
counsel that an exemption from registration is available for such resale.  As to
certain of the Purchasers which are not U.S. persons within the meaning of
Regulation S, the offer and sale contemplated hereunder has been and will be
made in an "offshore transaction" with no "directed selling efforts" in the U.S.
(all within the meaning of Regulation S), and each such Purchaser has agreed and
hereby confirms that during the Holding Period (as defined below) commencing on
the Closing Date, no offer or sale of any Purchased Securities shall be made in
the U.S. or to a "U.S. person" (as defined in Regulation S) or for the account
or benefit of a "U.S. person."  The "Holding Period" shall expire on the 360th
day after the Closing Date.  With regard to the restrictions on resales of the
Purchased Securities or 


                                    Page 34 of 73
<PAGE>

any security underlying or into which the Purchased Securities are or may be
convertible, Purchasers are aware (i) of the limitations and applicability of
Securities and Exchange Commission Rule 144; (ii) that the Company will issue
stop transfer orders to its stock transfer agent in the event of attempts to
improperly transfer any such securities; and (iii) that a restrictive legend
will be placed on certificates representing the Purchased Securities and any
security underlying or into which any of the Purchased Securities are or will be
convertible, which legend will read substantially as follows: 


          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ISSUED
          PURSUANT TO A CLAIM OF EXEMPTION FROM THE REGISTRATION OR
          QUALIFICATION PROVISIONS OF THE SECURITIES ACT OF 1933, AS
          AMENDED (THE "ACT"), AND STATE SECURITIES LAWS AND THEREFORE HAVE
          NOT BEEN REGISTERED UNDER THE ACT OR UNDER THE SECURITIES LAWS OF
          ANY STATE.  THESE SECURITIES MAY NOT BE OFFERED, SOLD,
          TRANSFERRED, PLEDGED OR HYPOTHECATED WITHOUT COMPLIANCE WITH THE
          REGISTRATION OR QUALIFICATION PROVISIONS OF THE ACT OR APPLICABLE
          STATE LAWS, OR PURSUANT TO AN AVAILABLE EXEMPTION FROM SUCH
          REGISTRATION REQUIREMENTS  [AS TO HOLDERS WHICH ARE NOT "U.S.
          PERSONS" WITHIN THE MEANING OF REGULATION S].  SUBJECT TO CERTAIN
          REGISTRATION RIGHTS, THE HOLDER OF THESE SECURITIES HAS AGREED
          AND COVENANTED NOT TO OFFER OR SELL THESE SECURITIES IN THE
          UNITED STATES, ITS TERRITORIES OR POSSESSIONS, OR TO PERSONS
          KNOWN TO BE NATIONALS OR RESIDENTS OF THE UNITED STATES, UNTIL
          THE 361ST DAY FOLLOWING THE CLOSING DATE, 1998, AND THEREAFTER
          ONLY IF THE SHARES ARE REGISTERED UNDER THE ACT OR AN EXEMPTION
          FROM THE REGISTRATION REQUIREMENTS THEREUNDER IS AVAILABLE. 
          FURTHERMORE, THE COMPANY WILL INSTRUCT ITS STOCK TRANSFER AGENT
          NOT TO RECOGNIZE ANY SALE OF THESE SECURITIES UNLESS THE COMPANY
          HAS FIRST RECEIVED AN OPINION OF COUNSEL, SATISFACTORY TO THE
          COMPANY AND ITS SECURITIES COUNSEL, THAT AN EXEMPTION FROM SUCH
          REGISTRATION REQUIREMENTS IS AVAILABLE.


                                    Page 35 of 73

     13.  INDEMNIFICATION.  The Company agrees to indemnify each of the
Purchasers and their respective officers, employees and agents, and hold them
harmless from and against any and all liability, damage, cost or expense,
including attorney's fees, incurred on account or arising out of any inaccuracy
in or breach of the declarations, covenants, agreements, representations, and
warranties by the Company set forth herein.

     14.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company hereby
represents and warrants to Purchasers as follows:

          14.1  ORGANIZATION, STANDING, ETC.  The Company is duly organized,
     validly existing, and in good standing under the laws of the State of Utah,
     and has the requisite power and authority to enter into and perform this
     Agreement and to execute and perform under the documents, instruments and
     agreements related to this Agreement.

          14.2  AUTHORIZATION.  The execution and delivery of this Agreement and

     connection therewith constitute its legal, valid and binding obligation,
     enforceable against the Company in accordance with their respective terms,
     subject to laws of general application relating to the rights of creditors
     generally.

          14.3  ABSENCE OF CONFLICTS.  Neither the execution and delivery of the
     Transactions Documents or any other agreement or instrument to be delivered
     to the Purchasers in connection therewith, nor the consummation of the
     transactions contemplated thereby, by the Company, shall (i) conflict with
     or result in a breach of or constitute a violation or default under (A) any
     provision of the Articles of Incorporation or By-laws, each as amended to
     date, or the Company, or (B) the provision of any indenture, instrument or
     agreement to which the Company is a party or by which it or any of its
     properties is bound, or (C) any order, writ, judgment, award, injunction,
     decree, law, statute, rule or regulation, license or permit applicable to
     the Company; (ii) result in the creation or imposition of any lien pursuant
     to the terms of any such indenture, instrument or agreement, or constitute
     a breach of any fiduciary duty owned by the Company to any third party, or
     (iii) require the approval of any third party pursuant to any material
     contract, agreement, instrument, relationship or legal obligation to which
     the Company is subject or to which it or any of its properties, operations
     or management may be subject.

<PAGE>

          14.4  CAPITALIZATION.  The authorized capital stock of the Company
     consists of 50,000,000 shares of Common Stock par value $.001 per share. 
     As of April 30, 1997, 5,177,855 shares of Common Stock were issued and
     outstanding, 118,875 shares were held in the company's treasury, and
     1,862,600 shares were reserved for issuance in connection with options
     outstanding as shown on SCHEDULE II, attached.  All of the outstanding
     shares of Common Stock are, and the Common Shares and the shares of Common
     Stock to be issued to the Purchasers pursuant to exercise of the New
     Options will be, when paid for and issued, duly authorized, validly issued,
     fully paid and non-assessable and free of any preemptive rights.

          14.5  FINANCIAL STATEMENTS.  The Company, the Company's annual reports
     on Form 10-KSB for the fiscal years ended March 31, 1995 and 1996 (the
     "10-K'S"), and its quarterly reports on Form 10-QSB for the periods ended
     June 30, September 30, and December 31, 1995 and 1996 (the "10-QS"), and
     all 8-K's filed by the Company since March 31, 1995 (the "8-K'S") and its
     1995 and 1996 Annual Proxy Statements, copies of which have been filed with
     or furnished to the Securities and Exchange Commission, were when filed or
     furnished, accurate in all material respects and did not include any untrue
     statement of material fact or omit to state material facts necessary to
     make the statements therein not misleading.  The financial statements
     included in the 10-K's  and the 10-Qs present fairly the financial position
     of the Company at such dates and the results of its operations and cash
     flows for the periods then ended, in conformity with generally accepted
     accounting principles applied on a consistent basis throughout the periods
     covered by such statements.

     received formal notice of allowance for its initial patent application

     Company's technology, and (ii) such documents, materials and projections

     information concerning the Company set forth in this Agreement is complete
     and accurate in all material respects and does not contain any untrue
     statement of a material fact or omit to state a material fact required to

     were made, not misleading.  The Company is not aware of any facts or
     circumstances existing or any event which has had or which reasonably could
     be expected to have in the future a material adverse effect with respect to
     the financial condition, business, affairs or prospects of the Company

     ---------------------------------------------------------------------------

                                  OPTION TO PURCHASE
                                SHARES OF COMMON STOCK

     ---------------------------------------------------------------------------

     THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
     1933, AS AMENDED.  IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
     STATEMENT UNDER SUCH ACT, THESE SECURITIES MAY NOT BE OFFERED, SOLD,
     TRANSFERRED OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN APPLICABLE
     EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF SAID ACT AND UPON
     OBTAINING AN OPINION OF COUNSEL (WHICH MAY BE COUNSEL FOR THE
     COMPANY), SATISFACTORY TO THE COMPANY, THAT SUCH DISPOSITION MAY BE
     MADE WITHOUT REGISTRATION OF THE SECURITIES UNDER SUCH ACT, OR UNLESS
     SOLD PURSUANT TO RULE 144.  THE HOLDER OF THESE SECURITIES HAS AGREED
     AND COVENANTED NOT TO OFFER OR SELL THESE SECURITIES IN THE UNITED
     STATES, ITS TERRITORIES OR POSSESSIONS, OR TO PERSONS KNOWN TO BE
     NATIONALS OR RESIDENTS OF THE UNITED STATES, UNTIL THE EXPIRATION OF
     365 DAYS AFTER THE ISSUANCE THEREOF, AND THEREAFTER ONLY IF THE SHARES
     ARE REGISTERED UNDER THE ACT OR AN EXEMPTION FROM THE REGISTRATION
     REQUIREMENTS THEREUNDER IS AVAILABLE.


     THIS CERTIFIES THAT LCO INVESTMENTS LIMITED (the "HOLDER") is entitled to
purchase, on the terms hereof, 400,000 shares of Common Stock of ION LASER
TECHNOLOGY, INC. a Utah corporation (the "COMPANY"), subject to adjustment as
provided herein.



                                    Page 45 of 73
<PAGE>

     1.   EXERCISE OF OPTION.  The terms and conditions upon which this Option
may be exercised, and the Common Stock covered hereby (the "OPTION STOCK") may
be purchased, are as follows:

          1.1  TERM.  This Option may be exercised in whole or in part at any
time and from time to time commencing after the date hereof, but in no case may
this Option be exercised later than the close of business on May 1, 2007 (the
"TERMINATION DATE"), after which time this Option shall terminate and shall be
void and of no further force or effect.

          1.2  PURCHASE PRICE.  Except as adjusted pursuant to Section 2 hereof,
the per share purchase price for the shares of Common Stock to be issued upon
exercise of this Option shall be Nine Dollars ($9.00) per share of Common Stock
purchased.

          1.3   METHOD OF EXERCISE.  The exercise of the purchase rights
evidenced by this Option shall be effected by (a) the surrender of the Option,
together with a duly executed copy of the form of subscription attached hereto,
to the Company at its principal offices and (b) the delivery of the purchase
price by cashier's check payable to the Company's order for the number of shares
for which the purchase rights hereunder are being exercised.  In the event this
Option is exercised in part at any time and not in  whole, the Company shall
promptly issue and deliver to the Holder a replacement Option Agreement
reflecting the number of shares of Common Stock of the Company subject to such
Option after giving effect to such partial exercise.

          1.4  ISSUANCE OF SHARES.  Upon the exercise of the purchase rights
evidenced by this Option, a certificate or certificates for the purchased shares
shall be issued to the Holder as soon as practicable (and in any event within
three business days after exercise).

     2.   CERTAIN ADJUSTMENTS.

          2.1  MERGERS, CONSOLIDATIONS OR SALE OF ASSETS.  If at any time there
shall be a capital reorganization (other than a combination or subdivision of
Option Stock otherwise provided for herein), or a merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such reorganization, merger, consolidation or sale, lawful
provision shall be made so that the Holder shall thereafter be entitled to
receive upon exercise of this Option, during the period specified in this Option
and upon payment of the purchase price, the number of shares of stock or other
securities or property of the Company or the successor corporation resulting
from such reorganization, merger, consolidation or sale, to which a holder of
the Common Stock deliverable upon exercise of this Option would have been
entitled under the provisions of the agreement in such reorganization, merger,
consolidation or sale if this Option had been exercised 



                                    Page 46 of 73
<PAGE>

immediately before that reorganization, merger, consolidation or sale.  In any
such case, appropriate adjustment (as determined in good faith by the Company's
Board of Directors) shall be made in the application of the provisions of this
Option with respect to the rights and interests of the Holder after the
reorganization, merger, consolidation or sale to the end that the provisions of
this Option (including adjustment of the purchase price then in effect and the
number of shares of Option Stock) shall be applicable after that event, as near
as reasonably may be, in relation to any shares or other property deliverable
after that event upon exercise of this Option.

          2.2  SPLITS AND SUBDIVISIONS.  In the event the Company should at any
time or from time to time fix a record date for the effectuation of a split or
subdivision of the outstanding shares of Common Stock or the determination of
the holders of Common Stock entitled to receive a dividend or other distribution
payable in additional shares of Common Stock or other securities or rights
convertible into, or entitling the holder thereof to receive directly or
indirectly, additional shares of Common Stock (hereinafter referred to as the
"COMMON STOCK EQUIVALENTS") without payment of any consideration by such holder
for the additional shares of Common Stock or Common Stock Equivalents (including
the additional shares of Common Stock issuable upon conversion or exercise
thereof), then, as of such record date (or the date of such distribution, split
or subdivision if no record date is fixed), the purchase price hereunder shall
be appropriately decreased and the number of shares of Option Stock shall be
appropriately increased in proportion to such increase in outstanding shares.

          2.3  COMBINATION OF SHARES.  If the number of shares of Common Stock
outstanding at any time after the date hereof is decreased by a combination of
the outstanding shares of Common Stock, the purchase price hereunder shall be
appropriately increased and the number of shares of Option Stock shall be
appropriately decreased in proportion to such decrease in outstanding shares.

          2.4  OTHER ADJUSTMENTS.  If at any time on or before May 8, 1998 the
Company issues and sells pursuant to a public offering any shares of Common
Stock for a sale price less than $7.00 per share, or any securities convertible
into shares of Common Stock at a conversion price of less than $7.00 per share
(in either case, "DILUTIVE SECURITIES"), then, as of the date of issue of such
Dilutive Securities, the purchase price hereunder shall be appropriately
decreased to the purchase price or conversion price (as the case may be) of such
Dilutive Securities.

          2.5  CERTIFICATE AS TO ADJUSTMENTS.  In the case of each adjustment or
readjustment of the purchase price pursuant to this Section 2, the Company will
promptly compute such adjustment or readjustment in accordance with the terms
hereof and cause a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based
to be delivered to the Holder of this Option.  



                                    Page 47 of 73

The Company will, upon the written request at any time of the Holder of this
Option, furnish or cause to be furnished to such Holder a certificate setting

                              (a)  Such adjustments and readjustments;

                              (b)  The purchase price at the time in effect; and

                              (c)  The number of shares of Option Stock and the
                                   amount, if any, of other property at the time
                                   receivable upon the exercise of the Option.

     3.   FRACTIONAL SHARES.  No fractional shares shall be issued in connection
with any exercise of this Option.

     4.   RESERVATION OF COMMON STOCK.  The Company shall at all times reserve
and keep available out of its authorized but unissued shares of Common Stock,
solely for the purpose of effecting the exercise of this Option, such number of
its shares of Common Stock as shall from time to time be sufficient to effect
the exercise of this Option; and if at any time the number of authorized but
unissued shares of Common Stock shall not be sufficient to effect the exercise
of the entire Option, in addition to such other remedies as shall be available
to the Holder of this Option, the Company will use its reasonable best efforts
to take such corporate action as may, in the opinion of its counsel, be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purposes.

     5.   PRIVILEGE OF STOCK OWNERSHIP.  Prior to the exercise of this Option,
the Holder shall not be entitled, by virtue of holding this Option, to any
rights of a stockholder of the Company.

     6.   TRANSFERS AND EXCHANGES.

          6.1  Subject to the limitations set forth below and subject to
compliance with applicable federal and state securities laws, all or any part of
this Option and all rights hereunder are transferable in whole or in part by
Holder, provided such transfer is made in accordance with the provisions of that
certain Securities Purchase Agreement of even date herewith entered into by the
Holder, certain other Purchasers signatory thereto and the Company (the
"SECURITIES PURCHASE AGREEMENT").  The terms and conditions of such Securities
Purchase Agreement are hereby incorporated in and made a part of this Option
Agreement.  The transfer shall be recorded on the books of the Company upon the
surrender of this Option, properly endorsed, to the Company at its principal
offices and the payment to the Company of all transfer taxes and other
governmental charges imposed on such transfer.  In addition, the transferee
shall at the same time submit its written consent

and acknowledgment, by which the transferee shall covenant and agree to be bound
by and comply with the Securities Purchase Agreement.  In the event of a partial
transfer, the Company shall issue to the several holders one or more appropriate
new Options.  The Company may deem and treat the registered Holder as the
absolute owner of the Option (notwithstanding any notice of ownership or writing
thereon made by anyone other than the Company) for all purposes, and the Company
will not be affected by any notice to the contrary.  No rights under and by
virtue of this Option shall pass and be transferred separately and apart from
this Option.

          6.2  All new Options issued in connection with transfers, exchanges or
partial exercises shall be identical in form and provision to this Option except
as to the number of shares issuable upon exercise thereof.

     7.   SUCCESSORS AND ASSIGNS.  The terms and provisions of this Option
Agreement shall be binding upon the Company and the Holder and their respective
successors and assigns, subject at all times to the restrictions set forth in
this Option Agreement and the Securities Purchase Agreement.

     8.   LOSS, THEFT, DESTRUCTION OR MUTILATION OF OPTION.  Upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Option Agreement, and, in case of loss, theft
or destruction, of indemnity or security reasonably satisfactory to the Company,
and upon reimbursement to the Company of all reasonable expenses incidental
thereto, and upon surrender and cancellation of this Option Agreement, if
mutilated, the Company will make and deliver a new Option Agreement of like
tenor and dated as of such cancellation, in lieu of this Option Agreement.

     9.   AMENDMENT.  This Option Agreement and the terms of the Options may be
amended only with the written consent of the Holder and the Company set forth in
a writing specifying such amendment.

     10.  SATURDAYS, SUNDAYS, HOLIDAYS, ETC.  If the last or appointed day for
the taking of any action or the expiration of any right required or granted
herein shall be a Saturday or Sunday or shall be a legal holiday, then such
action may be taken or such right may be exercised, except as to the purchase
price, on the next succeeding day not a Saturday, Sunday or legal holiday.

     11.  NOTICES.  Any notice or demand authorized by this Option shall be
sufficiently given or made, if in writing and personally served, sent by
telecopy followed by written confirmation of receipt, or deposited in the United
States mail, registered or certified, return receipt requested, postage prepaid,

                                SHARES OF COMMON STOCK

         --------------------------------------------------------------------

     THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
     1933, AS AMENDED.  IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
     STATEMENT UNDER SUCH ACT, THESE SECURITIES MAY NOT BE OFFERED, SOLD,
     TRANSFERRED OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN APPLICABLE
     EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF SAID ACT AND UPON
     OBTAINING AN OPINION OF COUNSEL (WHICH MAY BE COUNSEL FOR THE
     COMPANY), SATISFACTORY TO THE COMPANY, THAT SUCH DISPOSITION MAY BE
     MADE WITHOUT REGISTRATION OF THE SECURITIES UNDER SUCH ACT, OR UNLESS
     SOLD PURSUANT TO RULE 144.


     THIS CERTIFIES THAT RICHARD S. BRADDOCK (the "HOLDER") is entitled to
purchase, on the terms hereof, 100,000 shares of Common Stock of ION LASER
TECHNOLOGY, INC. a Utah corporation (the "COMPANY"), subject to adjustment as
provided herein.

     1.   EXERCISE OF OPTION.  The terms and conditions upon which this Option
may be exercised, and the Common Stock covered hereby (the "OPTION STOCK") may
be purchased, are as follows:

          1.1  TERM.  This Option may be exercised in whole or in part at any
time and from time to time commencing after the date hereof, but in no case may
this Option be exercised later than the close of business on May 1, 2007 (the
"TERMINATION DATE"), after which time this Option shall terminate and shall be
void and of no further force or effect.

          1.2  PURCHASE PRICE.  Except as adjusted pursuant to Section 2 hereof,
the per share purchase price for the shares of Common Stock to be issued upon
exercise of this Option shall be Nine Dollars ($9.00) per share of Common Stock
purchased.

          1.3  METHOD OF EXERCISE.  The exercise of the purchase rights
evidenced by this Option shall be effected by (a) the surrender of the Option,
together with a duly executed copy of the form of subscription attached hereto,
to the Company at its 



                                    Page 52 of 73
<PAGE>

principal offices and (b) the delivery of the purchase price by cashier's check
payable to the Company's order for the number of shares for which the purchase
rights hereunder are being exercised.  In the event this Option is exercised in
part at any time and not in  whole, the Company shall promptly issue and deliver
to the Holder a replacement Option Agreement reflecting the number of shares of
Common Stock of the Company subject to such Option after giving effect to such
partial exercise.

          1.4  ISSUANCE OF SHARES.  Upon the exercise of the purchase rights
evidenced by this Option, a certificate or certificates for the purchased shares
shall be issued to the Holder as soon as practicable (and in any event within
three business days after exercise).

     2.   CERTAIN ADJUSTMENTS.

          2.1  MERGERS, CONSOLIDATIONS OR SALE OF ASSETS.  If at any time there
shall be a capital reorganization (other than a combination or subdivision of
Option Stock otherwise provided for herein), or a merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such reorganization, merger, consolidation or sale, lawful
provision shall be made so that the Holder shall thereafter be entitled to
receive upon exercise of this Option, during the period specified in this Option
and upon payment of the purchase price, the number of shares of stock or other
securities or property of the Company or the successor corporation resulting
from such reorganization, merger, consolidation or sale, to which a holder of
the Common Stock deliverable upon exercise of this Option would have been
entitled under the provisions of the agreement in such reorganization, merger,
consolidation or sale if this Option had been exercised immediately before that
reorganization, merger, consolidation or sale.  In any such case, appropriate
adjustment (as determined in good faith by the Company's Board of Directors)
shall be made in the application of the provisions of this Option with respect
to the rights and interests of the Holder after the reorganization, merger,
consolidation or sale to the end that the provisions of this Option (including
adjustment of the purchase price then in effect and the number of shares of
Option Stock) shall be applicable after that event, as near as reasonably may
be, in relation to any shares or other property deliverable after that event
upon exercise of this Option.

          2.2  SPLITS AND SUBDIVISIONS.  In the event the Company should at any
time or from time to time fix a record date for the effectuation of a split or
subdivision of the outstanding shares of Common Stock or the determination of
the holders of Common Stock entitled to receive a dividend or other distribution
payable in additional shares of Common Stock or other securities or rights
convertible into, or entitling the holder thereof to receive directly or
indirectly, additional shares of Common Stock (hereinafter referred to as the
"COMMON STOCK EQUIVALENTS") without payment of any consideration by such holder
for 



                                    Page 53 of 73
<PAGE>

the additional shares of Common Stock or Common Stock Equivalents (including the
additional shares of Common Stock issuable upon conversion or exercise thereof),
then, as of such record date (or the date of such distribution, split or
subdivision if no record date is fixed), the purchase price hereunder shall be
appropriately decreased and the number of shares of Option Stock shall be
appropriately increased in proportion to such increase in outstanding shares.

          2.3  COMBINATION OF SHARES.  If the number of shares of Common Stock
outstanding at any time after the date hereof is decreased by a combination of
the outstanding shares of Common Stock, the purchase price hereunder shall be
appropriately increased and the number of shares of Option Stock shall be
appropriately decreased in proportion to such decrease in outstanding shares.

          2.4  OTHER ADJUSTMENTS.  If at any time on or before May 1, 1998 the
Company issues and sells pursuant to a public offering any shares of Common
Stock for a sale price less than $7.00 per share, or any securities convertible
into shares of Common Stock at a conversion price of less than $7.00 per share
(in either case, "DILUTIVE SECURITIES"), then, as of the date of issue of such
Dilutive Securities, the purchase price hereunder shall be appropriately
decreased to the purchase price or conversion price (as the case may be) of such
Dilutive Securities.

          2.5  CERTIFICATE AS TO ADJUSTMENTS.  In the case of each adjustment or
readjustment of the purchase price pursuant to this Section 2, the Company will
promptly compute such adjustment or readjustment in accordance with the terms
hereof and cause a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based
to be delivered to the Holder of this Option.  The Company will, upon the
written request at any time of the Holder of this Option, furnish or cause to be
furnished to such Holder a certificate setting forth:

               (a)  Such adjustments and readjustments;

               (b)  The purchase price at the time in effect; and

               (c)  The number of shares of Option Stock and the amount, if any,
                    of other property at the time receivable upon the exercise
                    of the Option.

     3.   FRACTIONAL SHARES.  No fractional shares shall be issued in connection
with any exercise of this Option.

     4.   RESERVATION OF COMMON STOCK.  The Company shall at all times reserve
and keep available out of its authorized but unissued shares of Common Stock,
solely for the 



                                    Page 54 of 73
<PAGE>

purpose of effecting the exercise of this Option, such number of its shares of
Common Stock as shall from time to time be sufficient to effect the exercise of
this Option; and if at any time the number of authorized but unissued shares of
Common Stock shall not be sufficient to effect the exercise of the entire
Option, in addition to such other remedies as shall be available to the Holder
of this Option, the Company will use its reasonable best efforts to take such
corporate action as may, in the opinion of its counsel, be necessary to increase
its authorized but unissued shares of Common Stock to such number of shares as
shall be sufficient for such purposes.

     5.   PRIVILEGE OF STOCK OWNERSHIP.  Prior to the exercise of this Option,
the Holder shall not be entitled, by virtue of holding this Option, to any
rights of a stockholder of the Company.

     6.   TRANSFERS AND EXCHANGES.

          6.1  Subject to the limitations set forth below and subject to
compliance with applicable federal and state securities laws, all or any part of
this Option and all rights hereunder are transferable in whole or in part by
Holder, provided such transfer is made in accordance with the provisions of that
certain Securities Purchase Agreement of even date herewith entered into by the
Holder, certain other Purchasers signatory thereto and the Company (the
"SECURITIES PURCHASE AGREEMENT").  The terms and conditions of such Securities
Purchase Agreement are hereby incorporated in and made a part of this Option
Agreement.  The transfer shall be recorded on the books of the Company upon the
surrender of this Option, properly endorsed, to the Company at its principal
offices and the payment to the Company of all transfer taxes and other
governmental charges imposed on such transfer.  In addition, the transferee
shall at the same time submit its written consent and acknowledgment, by which
the transferee shall covenant and agree to be bound by and comply with the
Securities Purchase Agreement.  In the event of a partial transfer, the Company
shall issue to the several holders one or more appropriate new Options.  The
Company may deem and treat the registered Holder as the absolute owner of the
Option (notwithstanding any notice of ownership or writing thereon made by
anyone other than the Company) for all purposes, and the Company will not be
affected by any notice to the contrary.  No rights under and by virtue of this
Option shall pass and be transferred separately and apart from this Option.

          6.2  All new Options issued in connection with transfers, exchanges or
partial exercises shall be identical in form and provision to this Option except
as to the number of shares issuable upon exercise thereof.

     7.   SUCCESSORS AND ASSIGNS.  The terms and provisions of this Option
Agreement shall be binding upon the Company and the Holder and their respective 



                                    Page 55 of 73
<PAGE>

successors and assigns, subject at all times to the restrictions set forth in
this Option Agreement and the Securities Purchase Agreement.

     8.   LOSS, THEFT, DESTRUCTION OR MUTILATION OF OPTION.  Upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Option Agreement, and, in case of loss, theft
or destruction, of indemnity or security reasonably satisfactory to the Company,
and upon reimbursement to the Company of all reasonable expenses incidental
thereto, and upon surrender and cancellation of this Option Agreement, if
mutilated, the Company will make and deliver a new Option Agreement of like
tenor and dated as of such cancellation, in lieu of this Option Agreement.

     9.   AMENDMENT.  This Option Agreement and the terms of the Options may be
amended only with the written consent of the Holder and the Company set forth in
a writing specifying such amendment.

     10.  SATURDAYS, SUNDAYS, HOLIDAYS, ETC.  If the last or appointed day for
the taking of any action or the expiration of any right required or granted
herein shall be a Saturday or Sunday or shall be a legal holiday, then such
action may be taken or such right may be exercised, except as to the purchase
price, on the next succeeding day not a Saturday, Sunday or legal holiday.

     11.  NOTICES.  Any notice or demand authorized by this Option shall be
sufficiently given or made, if in writing and personally served, sent by
telecopy followed by written confirmation of receipt, or deposited in the United
States mail, registered or certified, return receipt requested, postage prepaid,

     THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
     1933, AS AMENDED.  IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
     STATEMENT UNDER SUCH ACT, THESE SECURITIES MAY NOT BE OFFERED, SOLD,
     TRANSFERRED OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN APPLICABLE
     EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF SAID ACT AND UPON
     OBTAINING AN OPINION OF COUNSEL (WHICH MAY BE COUNSEL FOR THE
     COMPANY), SATISFACTORY TO THE COMPANY, THAT SUCH DISPOSITION MAY BE
     MADE WITHOUT REGISTRATION OF THE SECURITIES UNDER SUCH ACT, OR UNLESS
     SOLD PURSUANT TO RULE 144.


     THIS CERTIFIES THAT LCO Investments Limited (the "HOLDER") is entitled to
purchase, on the terms hereof, 773,334 shares of Common Stock of ION LASER
TECHNOLOGY, INC. a Utah corporation (the "COMPANY"), subject to adjustment as
provided herein.

     1.   EXERCISE OF OPTION.  The terms and conditions upon which this Option
may be exercised, and the Common Stock covered hereby (the "OPTION STOCK") may
be purchased, are as follows:

          1.1  TERM.  This Option may be exercised in whole or in part at any
time commencing after the date hereof, but in no case may this Option be
exercised later than the close of business on March 31, 2006 (the "TERMINATION
DATE"), after which time this Option shall terminate and shall be void and of no
further force or effect.

          1.2  PURCHASE PRICE.  Except as adjusted pursuant to Section 2 hereof,
the per share purchase price for the shares of Common Stock to be issued upon
exercise of this Option shall be Nine Dollars ($9.00) per share of Common Stock

          1.3  METHOD OF EXERCISE.  The exercise of the purchase rights
evidenced by this Option shall be effected by (a) the surrender of the Option,
together with a duly executed copy of the form of subscription attached hereto,
to the Company at its principal offices and (b) the delivery of the purchase
price by cashier's check payable to the Company's order for the number of shares
for which the purchase rights hereunder are being exercised.  In the event this
Option is exercised in part at any time and not in  whole, the Company shall
promptly issue and deliver to the Holder a replacement Option Agreement 



                                    Page 60 of 73
<PAGE>

reflecting the number of shares of Common Stock of the Company subject to such
Option after giving effect to such partial exercise.

          1.4  ISSUANCE OF SHARES.  Upon the exercise of the purchase rights
evidenced by this Option, a certificate or certificates for the purchased shares
shall be issued to the Holder as soon as practicable (and in any event within
three business days after exercise).

     2.   CERTAIN ADJUSTMENTS.

          2.1  MERGERS, CONSOLIDATIONS OR SALE OF ASSETS.  If at any time there
shall be a capital reorganization (other than a combination or subdivision of
Option Stock otherwise provided for herein), or a merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such reorganization, merger, consolidation or sale, lawful
provision shall be made so that the Holder shall thereafter be entitled to
receive upon exercise of this Option, during the period specified in this Option
and upon payment of the purchase price, the number of shares of stock or other
securities or property of the Company or the successor corporation resulting
from such reorganization, merger, consolidation or sale, to which a holder of
the Common Stock deliverable upon exercise of this Option would have been
entitled under the provisions of the agreement in such reorganization, merger,
consolidation or sale if this Option had been exercised immediately before that
reorganization, merger, consolidation or sale.  In any such case, appropriate
adjustment (as determined in good faith by the Company's Board of Directors)
shall be made in the application of the provisions of this Option with respect
to the rights and interests of the Holder after the reorganization, merger,
consolidation or sale to the end that the provisions of this Option (including
adjustment of the purchase price then in effect and the number of shares of
Option Stock) shall be applicable after that event, as near as reasonably may
be, in relation to any shares or other property deliverable after that event
upon exercise of this Option.

          2.2  SPLITS AND SUBDIVISIONS.  In the event the Company should at any
time or from time to time fix a record date for the effectuation of a split or
subdivision of the outstanding shares of Common Stock or the determination of
the holders of Common Stock entitled to receive a dividend or other distribution
payable in additional shares of Common Stock or other securities or rights
convertible into, or entitling the holder thereof to receive directly or
indirectly, additional shares of Common Stock (hereinafter referred to as the
"COMMON STOCK EQUIVALENTS") without payment of any consideration by such holder
for the additional shares of Common Stock or Common Stock Equivalents (including
the additional shares of Common Stock issuable upon conversion or exercise
thereof), then, as of such record date (or the date of such distribution, split
or subdivision if no record date is fixed), the purchase price hereunder shall
be appropriately decreased and the number of 



                                    Page 61 of 73
<PAGE>

shares of Option Stock shall be appropriately increased in proportion to such
increase in outstanding shares.

          2.3  COMBINATION OF SHARES.  If the number of shares of Common Stock
outstanding at any time after the date hereof is decreased by a combination of
the outstanding shares of Common Stock, the purchase price hereunder shall be
appropriately increased and the number of shares of Option Stock shall be
appropriately decreased in proportion to such decrease in outstanding shares.

          2.4  CERTIFICATE AS TO ADJUSTMENTS.  In the case of each adjustment or
readjustment of the purchase price pursuant to this Section 2, the Company will
promptly compute such adjustment or readjustment in accordance with the terms
hereof and cause a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based
to be delivered to the Holder of this Option.  The Company will, upon the
written request at any time of the Holder of this Option, furnish or cause to be
furnished to such Holder a certificate setting forth:

              (a)  Such adjustments and readjustments;

              (b)  The purchase price at the time in effect; and

              (c)  The number of shares of Option Stock and the amount, if any,
                   of other property at the time receivable upon the exercise
                   of the Option.

     3.   FRACTIONAL SHARES.  No fractional shares shall be issued in connection
with any exercise of this Option.

     4.   RESERVATION OF COMMON STOCK.  The Company shall at all times reserve
and keep available out of its authorized but unissued shares of Common Stock,
solely for the purpose of effecting the exercise of this Option, such number of
its shares of Common Stock as shall from time to time be sufficient to effect
the exercise of this Option; and if at any time the number of authorized but
unissued shares of Common Stock shall not be sufficient to effect the exercise
of the entire Option, in addition to such other remedies as shall be available
to the Holder of this Option, the Company will use its reasonable best efforts
to take such corporate action as may, in the opinion of its counsel, be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purposes.

     5.   PRIVILEGE OF STOCK OWNERSHIP.  Prior to the exercise of this Option,
the Holder shall not be entitled, by virtue of holding this Option, to any
rights of a stockholder of the Company.

     6.   TRANSFERS AND EXCHANGES.

          6.1  Subject to the limitations set forth below and subject to
compliance with applicable federal and state securities laws, all or any part of
this Option and all rights hereunder are transferable in whole or in part by
Holder, provided such transfer is made in accordance with the provisions of that
certain Securities Purchase Agreement of even date herewith entered into by the
Holder, certain other Purchasers signatory thereto and the Company (the
"SECURITIES PURCHASE AGREEMENT").  The terms and conditions of such Securities
Purchase Agreement are hereby incorporated in and made a part of this Option
Agreement.  The transfer shall be recorded on the books of the Company upon the
surrender of this Option, properly endorsed, to the Company at its principal
offices and the payment to the Company of all transfer taxes and other
governmental charges imposed on such transfer.  In addition, the transferee
shall at the same time submit its written consent and acknowledgment, by which
the transferee shall covenant and agree to be bound by and comply with the
Securities Purchase Agreement.  In the event of a partial transfer, the Company
shall issue to the several holders one or more appropriate new Options.  The
Company may deem and treat the registered Holder as the absolute owner of the
Option (notwithstanding any notice of ownership or writing thereon made by
anyone other than the Company) for all purposes, and the Company will not be
affected by any notice to the contrary.  No rights under and by virtue of this
Option shall pass and be transferred separately and apart from this Option.

          6.2  All new Options issued in connection with transfers, exchanges or
partial exercises shall be identical in form and provision to this Option except
as to the number of shares issuable upon exercise thereof.

     7.   SUCCESSORS AND ASSIGNS.  The terms and provisions of this Option
Agreement shall be binding upon the Company and the Holder and their respective
successors and assigns, subject at all times to the restrictions set forth in
this Option Agreement and the Securities Purchase Agreement.

     8.   LOSS, THEFT, DESTRUCTION OR MUTILATION OF OPTION.  Upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Option Agreement, and, in case of loss, theft
or destruction, of indemnity or security reasonably satisfactory to the Company,
and upon reimbursement to the Company of all reasonable expenses incidental
thereto, and upon surrender and cancellation of this Option Agreement, if
mutilated, the Company will make and deliver a new Option Agreement of like
tenor and dated as of such cancellation, in lieu of this Option Agreement.

amended only with the written consent of the Holder and the Company set forth in
a writing specifying such amendment.

price, on the next succeeding day not a Saturday, Sunday or legal holiday.

be purchased, are as follows:

          1.1  TERM.  This Option may be exercised in whole or in part at any
time commencing after the date hereof, but in no case may this Option be

receive upon exercise of this Option, during the period specified in this Option
and upon payment of the purchase price, the number of shares of stock or other
securities or property of the Company or the successor corporation resulting
from such reorganization, merger, consolidation or sale, to which a holder of

indirectly, additional shares of Common Stock (hereinafter referred to as the
"COMMON STOCK EQUIVALENTS") without payment of any consideration by such holder
for the additional shares of Common Stock or Common Stock Equivalents (including
the additional shares of Common Stock issuable upon conversion or exercise
thereof), then, as of such record date (or the date of such distribution, split
or subdivision if no record date is fixed), the purchase price hereunder shall
be appropriately decreased and the number of shares of Option Stock shall be
appropriately increased in proportion to such increase in outstanding shares.

          2.3  COMBINATION OF SHARES.  If the number of shares of Common Stock
outstanding at any time after the date hereof is decreased by a combination of
the 



                                    Page 69 of 73
<PAGE>

outstanding shares of Common Stock, the purchase price hereunder shall be

appropriately decreased in proportion to such decrease in outstanding shares.

          2.4  CERTIFICATE AS TO ADJUSTMENTS.  In the case of each adjustment or
readjustment of the purchase price pursuant to this Section 2, the Company will

with any exercise of this Option.

     4.   RESERVATION OF COMMON STOCK.  The Company shall at all times reserve
and keep available out of its authorized but unissued shares of Common Stock,
solely for the purpose of effecting the exercise of this Option, such number of
its shares of Common Stock as shall from time to time be sufficient to effect
the exercise of this Option; and if at any time the number of authorized but
unissued shares of Common Stock shall not be sufficient to effect the exercise
of the entire Option, in addition to such other remedies as shall be available
to the Holder of this Option, the Company will use its reasonable best efforts
to take such corporate action as may, in the opinion of its counsel, be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purposes.

     5.   PRIVILEGE OF STOCK OWNERSHIP.  Prior to the exercise of this Option,
the Holder shall not be entitled, by virtue of holding this Option, to any
rights of a stockholder of the Company.

     6.   TRANSFERS AND EXCHANGES.

          6.1  Subject to the limitations set forth below and subject to
compliance with applicable federal and state securities laws, all or any part of
this Option 



                                    Page 70 of 73
<PAGE>

and all rights hereunder are transferable in whole or in part by Holder,
provided such transfer is made in accordance with the provisions of that certain
Securities Purchase Agreement of even date herewith entered into by the Holder,
certain other Purchasers signatory thereto and the Company (the "SECURITIES
PURCHASE AGREEMENT").  The terms and conditions of such Securities Purchase
Agreement are hereby incorporated in and made a part of this Option Agreement. 
The transfer shall be recorded on the books of the Company upon the surrender of
this Option, properly endorsed, to the Company at its principal offices and the
payment to the Company of all transfer taxes and other governmental charges
imposed on such transfer.  In addition, the transferee shall at the same time
submit its written consent and acknowledgment, by which the transferee shall
covenant and agree to be bound by and comply with the Securities Purchase
Agreement.  In the event of a partial transfer, the Company shall issue to the
several holders one or more appropriate new Options.  The Company may deem and
treat the registered Holder as the absolute owner of the Option (notwithstanding
any notice of ownership or writing thereon made by anyone other than the
Company) for all purposes, and the Company will not be affected by any notice to
the contrary.  No rights under and by virtue of this Option shall pass and be
transferred separately and apart from this Option.


          6.2  All new Options issued in connection with transfers, exchanges or
partial exercises shall be identical in form and provision to this Option except
as to the number of shares issuable upon exercise thereof.

     7.   SUCCESSORS AND ASSIGNS.  The terms and provisions of this Option
Agreement shall be binding upon the Company and the Holder and their respective
successors and assigns, subject at all times to the restrictions set forth in
this Option Agreement and the Securities Purchase Agreement.

     8.   LOSS, THEFT, DESTRUCTION OR MUTILATION OF OPTION.  Upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Option Agreement, and, in case of loss, theft
or destruction, of indemnity or security reasonably satisfactory to the Company,
and upon reimbursement to the Company of all reasonable expenses incidental
thereto, and upon surrender and cancellation of this Option Agreement, if
mutilated, the Company will make and deliver a new Option Agreement of like
tenor and dated as of such cancellation, in lieu of this Option Agreement.

     9.   AMENDMENT.  This Option Agreement and the terms of the Options may be
amended only with the written consent of the Holder and the Company set forth in
a writing specifying such amendment.

     10.  SATURDAYS, SUNDAYS, HOLIDAYS, ETC.  If the last or appointed day for
the taking of any action or the expiration of any right required or granted
herein shall be a Saturday or Sunday or shall be a legal holiday, then such
action may be taken or such right 



                                    Page 71 of 73
<PAGE>

may be exercised, except as to the purchase price, on the next succeeding day
not a Saturday, Sunday or legal holiday.

     11.  NOTICES.  Any notice or demand authorized by this Option shall be
sufficiently given or made, if in writing and personally served, sent by
telecopy followed by written confirmation of receipt, or deposited in the United
States mail, registered or certified, return receipt requested, postage prepaid,
at or to the address or telecopy number as the receiving party shall have

deemed given on the date of service if personally served or if sent by telecopy.

courier service, or on the third business day following the date mailed.

investment purposes, and not with a view to any offer or distribution thereof
