                  862,667 shares of (no par value) common stock


         The securityholders listed in this Prospectus under the section
"Registered Securityholders" may offer and sell a total of 862,667 shares of our
company's common stock, no par value, which shares are issuable upon conversion
of convertible debentures (the "Debentures") previously issued to such
securityholders. This Prospectus has been prepared for the purposes of
registering the shares under the Securities Act of 1933, as amended (the
"Securities Act"), and to allow the Registered Securityholders to make future
sales to the public without restriction. To our knowledge, the Registered
Securityholders have made no arrangement with any brokerage firm for the sale of
the shares.

         The Registered Securityholders may sell their shares of common stock
described in this Prospectus for their own benefit in public or private
transactions, on or off the Nasdaq National Market, at prevailing market prices,
or at privately negotiated prices. The Registered Securityholders may sell the
shares directly to purchasers or through brokers or dealers. Brokers or dealers
may receive compensation in the form of discounts, concessions or commissions
from the Registered Securityholders. The compensation to a particular
underwriter, broker-dealer or agent may be in excess of customary commissions.
The Registered Securityholders will pay all commissions, transfer taxes and
other expenses associated with their sales of the shares. We will pay the
expenses of the preparation of this Prospectus. We have also agreed to indemnify
certain Registered Securityholders against certain liabilities, including,
without limitation, liabilities arising under the Securities Act. We will not
receive any of the proceeds from the Registered Securityholders' sales of the
shares. In addition to sales under this Prospectus, the Registered
Securityholders may also engage in other sales of shares under Rule 144 or other
exempt resale transactions. There can be no assurance that any or all of the
Registered Securityholders will sell any or all of the shares offered pursuant
this Prospectus. More information is provided in the section titled "Plan of
Distribution."

         Our common stock is listed on the Nasdaq National Market under the
symbol "PLSIA." On December 3, 1999, the last reported sale price of our common
stock on the Nasdaq National Market was $1.75 per share.

                                  RISK FACTORS

         Before you invest in our common stock, you should be aware that there
are various risks, including those described below. You should carefully
consider these risk factors, together with all the other information included in
this prospectus, before you decide whether to purchase shares of our common
stock.

THERE ARE RISKS ASSOCIATED WITH FORWARD-LOOKING STATEMENTS MADE BY US AND ACTUAL
RESULTS MAY DIFFER.

         Some of the information in this prospectus contains forward-looking
statements that involve substantial risks and uncertainties. You can identify
these statements by forward-looking words such as "may," "will," "expect,"
"anticipate," "believe," "estimate," and "continue" or similar words. You should
read statements that contain these words carefully because they:

         o        discuss our future expectations

         o        contain projections of our future results of operations or of
                  our financial condition

         o        state other "forward-looking" information

         We believe it is important to communicate our expectations to our
investors. However, there may be events in the future that we are not able to
accurately predict or over which we have no control. The risk factors listed in
this section, as well as any cautionary language in this prospectus, provide
examples of risks, uncertainties and events that may cause our actual results to
differ materially from the expectations we describe in our forward-looking
statements. Before you invest in our common stock, you should be aware that the
occurrence of the events described in these risk factors and elsewhere in this
prospectus could have a material adverse effect on our business, results of
operations and financial condition.

RISKS RELATED TO OUR BUSINESS

IF WE ARE UNABLE TO SECURE ADDITIONAL FINANCING IN THE FUTURE, WE WILL HAVE
SEVERE DIFFICULTIES FINANCING OUR BUSINESS.

         In the future, we will require substantial additional funds for
operating expenses, research and development programs, preclinical and clinical
testing, development of our sales and distribution force, operating expenses,
regulatory processes and manufacturing and marketing programs. Our capital
requirements may vary, and will depend on both internal and external factors.
Internal factors affecting our capital requirements include:

         o        our ability to generate profits and cash flow from operations

         o        the progress of research and development programs

                                        2
<PAGE>

         o        results of preclinical and clinical testing

         o        the cost of filing, prosecuting, defending and enforcing any
                  patent claims and other intellectual property rights

         o        developments and changes in our existing research

         o        licensing and other relationships

         o        the terms of any new collaborative, licensing and other
                  arrangements that we may establish

         o        the amount of legal, accounting and administrative costs
                  incurred in connection with pending litigation

         External factors affecting our capital requirements include:

         o        competing technological and market developments

         o        the time and cost involved in obtaining regulatory approvals

         Our available short-term assets and investment income will not be
sufficient to meet our operating expenses and capital expenditures through the
current fiscal year, and we are currently seeking additional financing. We do
not know if additional financing will be available when needed, or if it is
available, if it will be available on acceptable terms. Insufficient funds may
prevent us from implementing our business strategy or may require us to delay,
scale back or eliminate research and product development programs or to license
to third parties rights to commercialize products or technologies that we would
otherwise seek to develop internally.

WE HAVE INCURRED NET LOSSES IN THE PAST AND EXPECT TO INCUR FUTURE LOSSES WHICH
MAY NEGATIVELY IMPACT OUR ABILITY TO SUSTAIN OUR OPERATIONS.

         We incurred net losses of approximately $76,343,000 from April 1, 1995
through March 31, 1999, and approximately $30,841,000 for the year ended March
31, 1999. As of September 30, 1999, we had an accumulated deficit of
approximately $94,301,996. We expect to continue to incur net losses until
product sales generate sufficient revenues to fund our continuing operations. We
may fail to achieve significant revenues from sales or achieve or sustain
profitability. Our ability to achieve profitability in the future will depend in
part on our ability to continue to successfully develop clinical applications,
obtain regulatory approvals for our products and sell these products on a wide
scale. These risks apply to both our laser products and our ophthalmic
diagnostic products.

THE HIGH COST OF DENTAL LASERS, SAFETY AND EFFICACY CONCERNS OF DENTISTS AND
PATIENTS AND THE SUBSTANTIAL MARKET ACCEPTANCE OF DENTAL DRILLS MAY PREVENT US
FROM ACHIEVING THE BROAD MARKET ACCEPTANCE WHICH IS NECESSARY FOR OUR SUCCESS.

         Our products may not be accepted by the medical or dental community or
by patients. We do not know if these products can be successfully commercialized
on a broad basis. The acceptance of dental lasers may be adversely affected by
their high cost, concerns by patients and dentists relating to their safety and
efficacy, and the substantial market acceptance and penetration of alternative
dental tools such as the dental drill. Our future sales and profitability depend
in part on our ability to demonstrate to dentists, ophthalmologists,
optometrists and other physicians the potential cost and performance advantages
of our laser systems, diagnostic products and other products over traditional
methods of treatment and over competitive products. Current economic pressure
may make doctors and dentists reluctant to purchase substantial capital

                                        3
<PAGE>

equipment or invest in new technology. We currently have a limited sales force
and will need to hire additional sales and marketing personnel to increase the
general acceptance of our products. Of all the factors impacting our
profitability, the failure of our products to achieve broad market acceptance
would have the greatest negative impact on our business, financial condition and
results of operations and our profitability.

WE ARE INVOLVED IN PENDING LITIGATION AND A REGULATORY INVESTIGATION AND MAY BE
ADVERSELY AFFECTED BY AN ADVERSE OUTCOME IN THE LAWSUIT OR BY THE COSTS OF
DEFENDING THIS LAWSUIT.

         We have been sued in a number of related securities class action
matters, generally relating to allegations of misrepresentations during the
period from May 7, 1997 to April 15, 1998. We have reached an agreement in
principle to settle this litigation and recorded an expense in the quarter ended
December 31, 1998, relating to this settlement. In the quarter ended March 31,
1999, we recorded an additional expenses of $250,000 to cover continuing legal
fees incurred in connection with this settlement. However, this settlement is
subject to several conditions, and it is possible that it may not be completed,
in which case the litigation would continue. An adverse judgment entered in this
litigation could materially and adversely affect our business and results of
operations. In addition, the Securities and Exchange Commission has commenced an
investigation of our practices and procedures relating to revenue recognition
issues and related matters. The Securities and Exchange Commission has begun
taking depositions of past and present employees as well as our outside
accountants. The costs of our continuing defense of the litigation matters and
responses to the regulatory investigations, including accounting and legal fees
as well as management time and effort, will be substantial, and we expect these
costs to materially and adversely affect our results of operations until these
matters are resolved. We do not know when these matters will be resolved.

         In addition, the Securities and Exchange Commission is empowered to
assess substantial penalties against us in connection with its findings in the
pending investigation. The imposition of any of these penalties could materially
and adversely affect our business, financial condition and results of
operations.

IF WE ARE UNABLE TO SUCCESSFULLY INTEGRATE THE OPHTHALMIC IMAGING SYSTEMS
("OIS") BUSINESS WITH OUR OTHER OPERATIONS, WE MAY INCUR SUBSTANTIAL AND
UNANTICIPATED EXPENSES AND OPERATING INEFFICIENCIES.

         We acquired a majority of the outstanding common stock of OIS in 1998.
In March 1999, we agreed to manufacture OIS's products on an outsourcing basis.
In addition, we have agreed with OIS to acquire the remaining outstanding stock
of OIS, subject to satisfaction of certain conditions. We are not sure if the
synergies of the two entities will allow us to reduce expenses in such a way as
to make OIS profitable. In addition, members of our management will have to
continue to expend time and effort on new activities relating to the OIS
operations, which will detract from their time available to attend to our other
activities. We cannot assure you that the expenses or dislocations that we may
suffer as a result of the coordination of these businesses will not be material.

BECAUSE SOME OF THE COMPONENTS WE USE ARE NOT WIDELY AVAILABLE, THERE IS A RISK
THAT WE MAY NOT ALWAYS BE ABLE TO OBTAIN THESE COMPONENTS, WHICH COULD PREVENT
US FROM FILLING ORDERS ON TIME AND REDUCE OUR SALES.

         We purchase some of the raw materials, components and subassemblies
included in our products from a limited group of qualified suppliers and do not
maintain long-term supply contracts with any of our key suppliers. Some of the
components used by OIS are manufactured by a sole vendor, including Foresight
Imaging for its prism card and Kodak for its 12 bit camera. In addition, our
Arago laser product is manufactured for us by one supplier, LaserMed, Inc.
Further, our components are subject to rapid innovation and obsolescence. The
discontinuance of the manufacturing of these components may require us to
redesign some of the hardware and software used in our products to accommodate a

                                        4
<PAGE>

replacement component. While we believe that suppliers could be found for all of
our components and products, we cannot assure you that any supplier could be
replaced in a timely manner. Any interruption in the supply of key components
could materially harm our ability to manufacture our products and our business,
financial condition and results of operations.

IN ORDER TO CONTINUE TO SELL OUR PRODUCTS IN FOREIGN MARKETS, WE MUST DEVELOP
AND MAINTAIN FOREIGN SALES DISTRIBUTION CHANNELS AND MANAGE POLITICAL AND
ECONOMIC INSTABILITY IN FOREIGN MARKETS AND DEAL WITH GOVERNMENTAL QUOTAS AND
OTHER REGULATIONS.

         A substantial portion of our sales are made in foreign markets. The
primary risks to which we are exposed due to our foreign sales are the
difficulty and expense of maintaining foreign sales distribution channels,
political and economic instability in foreign markets and governmental quotas
and other regulations.

         The regulation of medical devices worldwide also continues to develop,
and it is possible that new laws or regulations could be enacted which would
have an adverse effect on our business. In addition, we may experience
additional difficulties in providing prompt and cost effective service of our
medical lasers in foreign countries. We do not carry insurance against these
risks. The occurrence of any one or more of these events may individually or in
the aggregate have a material adverse effect upon our business, financial
condition and results of operations.

IF WE CANNOT ADAPT TO TECHNOLOGICAL ADVANCES, OUR PRODUCTS MAY BECOME
TECHNOLOGICALLY OBSOLETE AND OUR PRODUCT SALES COULD SIGNIFICANTLY DECLINE.

         The markets in which our medical products compete are subject to rapid
technological change as well as the potential development of alternative
surgical techniques or new pharmaceutical products. These changes could render
our products uncompetitive or obsolete. We will be required to invest in
research and development to attempt to maintain and enhance our existing
products and develop new products. We do not know if our research and
development efforts will result in the introduction of new products or product
improvements.

IF WE ARE UNABLE TO PROTECT OUR PATENTS AND PROPRIETARY TECHNOLOGY WE MAY NOT BE
ABLE TO COMPETE EFFECTIVELY.

         Our success will depend in part on our ability to obtain patent
protection for products and processes, to preserve our trade secrets and to
operate without infringing the proprietary rights of third parties. While we
hold a number of U.S. and foreign patents and have other patent applications
pending in the United States and foreign countries, we cannot assure you that
any additional patents will be issued, that the scope of any patent protection
will exclude competitors or that any of our patents will be held valid if
subsequently challenged. Further, other companies may independently develop
similar products, duplicate our products or design products that circumvent our
patents. We are aware of certain patents which, along with other patents that
may exist or be granted in the future, could restrict our right to market some
of our technologies without a license, including, among others, patents relating
to our lens emulsification product and ophthalmic probes for the Er:YAG laser.

         We also rely upon unpatented trade secrets, and we cannot assure you
that others will not independently develop or otherwise acquire substantially
equivalent trade secrets. In addition, at each balance sheet date, we are
required to review the value of our intangible assets based on various factors,
such as changes in technology. Any adjustment downward in the value of our
intangible assets may result in a write-off of the intangible asset and a
substantial charge to earnings, which would adversely affect our operating
results in the future.

                                        5
<PAGE>

IN OUR BUSINESS, WE COULD BECOME INVOLVED IN PATENT AND INTELLECTUAL PROPERTY
LITIGATION, IN WHICH AN ADVERSE DETERMINATION COULD SUBJECT US TO SIGNIFICANT
LIABILITIES AND RESTRICT OUR MANUFACTURING RIGHTS.

         In the past, we have received allegations that some of our laser and
diagnostic products infringe on other patents. There has been significant patent
litigation in the medical device industry. Adverse determinations in litigation
or other patent proceedings to which we may become a party could subject us to
significant legal judgments or other liabilities to third parties and could
require us to seek licenses from third parties that may or may not be
economically viable. We cannot assure you that any licenses required under these
or any other patents or proprietary rights would be available on terms
acceptable to us. If we do not obtain these licenses, we could encounter delays
in product introductions while we attempt to design around these patents, or we
could find that the development, manufacture or sale of products requiring such
licenses could be enjoined.

OUR BUSINESS IS SUBJECT TO GOVERNMENTAL REGULATION WHICH IMPOSES SIGNIFICANT
COSTS ON US AND IF NOT COMPLIED WITH COULD LEAD TO THE ASSESSMENT OF PENALTIES.

         Our products are regulated as medical devices by the United States Food
& Drug Administration. As such, these devices require either Section 510(k)
premarket clearance or approval of a premarket approval application by the FDA
prior to commercialization. Satisfaction of regulatory requirements is expensive
and may take several years to complete. We cannot assure you that further
clinical trials of our medical products or of any future products will be
successfully completed or, if they are completed, that any requisite FDA or
foreign governmental approvals will be obtained.

         FDA or other governmental approvals of products we may develop in the
future may require substantial filing fees which could limit the number of
applications we seek and may entail limitations on the indicated uses for which
our products may be marketed. In addition, approved or cleared products may be
subject to additional testing and surveillance programs required by the FDA and
other regulatory agencies, and product approvals and clearances could be
withdrawn for failure to comply with regulatory standards or by the occurrence
of unforeseen problems following initial marketing. Also, we have made
modifications to some of our existing products which we do not believe require
the submission of a new 510(k) notification to the FDA. However, we cannot
assure you that the FDA would agree with our determination. If the FDA did not
agree with our determination, they could require us to cease marketing one or
more of the modified devices until the devices have been cleared.

         We are also required to adhere to a wide variety of other regulations
governing the operation of our business. Noncompliance with state, local,
federal or foreign requirements can result in serious penalties that could harm
our business.

THE INTENSE COMPETITION WE FACE COULD RESULT IN REDUCED SALES AND DOWNWARD
PRESSURE ON THE PRICES OF OUR PRODUCTS.

         We are, and will continue to be, subject to intense competition in our
targeted markets, principally from businesses providing other traditional
surgical and nonsurgical treatments, including existing and developing
technologies, and competitive products. Many of our competitors have
substantially greater financial, marketing and manufacturing resources and
experience than us. In addition, we expect that other companies will enter the
laser market, particularly as medical lasers gain increasing market acceptance.
Significant competitive factors which will affect future sales in the
marketplace include regulatory approvals, performance, pricing and general
market acceptance.

         The ophthalmic diagnostic market is also highly competitive. There are
many companies engaged in this market, some with significantly greater resources
than ours. Our competitors may be able to develop technologies, procedures or
products that are more effective or economical than ours, or that would render
our products obsolete or noncompetitive.

                                        6
<PAGE>

         To continue to remain competitive, we must develop new software and
hardware meeting the needs of ophthalmologists and optometrists. Our future
revenues will depend, in part, on our ability to develop and commercialize these
new products as well as on the success of development and commercialization
efforts of our competitors.

A SUCCESSFUL PRODUCT LIABILITY CLAIM ASSERTED AGAINST US DUE TO A DEFECT IN ONE
OF OUR PRODUCTS IN EXCESS OF OUR INSURANCE COVERAGE WOULD HARM OUR BUSINESS.

         The sale of our medical products involves the inherent risk of product
liability claims against us. We currently maintain product liability insurance
coverage in the amount of $5 million per occurrence and $5 million in the
aggregate, but this insurance is expensive, subject to various coverage
exclusions and may not be obtainable in the future on terms acceptable to us. We
do not know whether claims against us arising with respect to our products will
be successfully defended or that our insurance will be sufficient to cover
liabilities arising from these claims. A successful claim against us in excess
of our insurance coverage could materially harm our business.

THERE IS UNCERTAINTY RELATING TO THIRD PARTY REIMBURSEMENT WHICH IS CRITICAL TO
MARKET ACCEPTANCE OF OUR PRODUCTS.

         Our laser systems and other products are generally purchased by
physicians, dentists and surgical centers which then bill various third party
payors, such as government programs and private insurance plans, for the
procedures conducted using these products. Third-party payors carefully review
and are increasingly challenging the prices charged for medical products and
services, and scrutinizing whether to cover new products and evaluating the
level of reimbursement for covered products. While we believe that the
procedures using our products have generally been reimbursed, payors may deny
coverage and reimbursement for our products if they determine that the device
was not reasonable and necessary for the purpose for which it was used, was
investigational or not cost-effective. As a result, we cannot assure you that
reimbursement from third party payors for these procedures will be available or
if available, that reimbursement will not be limited. If third party
reimbursement of these procedures is not available, it will be more difficult
for us to sell our products on a profitable basis. Moreover, we are unable to
predict what legislation or regulation, if any, relating to the health care
industry or third-party coverage and reimbursement may be enacted in the future,
or what effect such legislation or regulation may have on us.

THE COVERAGE AND SPENDING LIMITATIONS CONTAINED IN HEALTH CARE REFORM PROPOSALS
WOULD, IF ADOPTED, REDUCE DEMAND FOR OUR PRODUCTS.

         Several states and the United States government are investigating a
variety of alternatives to reform the health care delivery system and further
reduce and control health care spending. These reform efforts include proposals
to limit spending on health care items and services, limit coverage for new
technology and limit or control the price health care providers and drug and
device manufacturers may charge for their services and products. If adopted and
implemented, such reforms could have a material adverse effect on our business,
financial condition and results of operations.

IF WE EXPERIENCE PROBLEMS WITH YEAR 2000 COMPLIANCE OUR OPERATIONS MAY BE
DISRUPTED.

         Many existing computer programs use only two digits to identify the
year in the date field. These programs were designed and developed without
considering the impact of the upcoming change in the century. As a result, any
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the Year 2000. This could result in system
failure or miscalculations, causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices or
engage in similar normal business activities.

                                        7
<PAGE>

         We are heavily dependent upon the proper functioning of our own
computer and data-dependent systems. This includes, but it not limited to, our
support/administrative and operational/production systems. Any failure or
malfunctioning on the part of these or other systems could harm our business in
ways that we currently do not know and cannot discern, quantify or otherwise
anticipate. In addition, if our key vendors experience Year 2000 compliance
issues, then our business could be harmed. Due to the interrelated nature of
international commerce, if there is a failure in Year 2000 compliance by us or
one of our direct or indirect business partners, we could suffer major
disruptions in our ability to call on customers, obtain orders from customers,
obtain parts from suppliers, manufacture products for sale, ship products to our
customers, or receive payment for our sales.

         We are currently in the final phase of identifying and evaluating the
potential impacts of the Year 2000 on our systems. We design, manufacture and
sell medical products which contain computer chips and we utilize software
developed by other companies. We rely on external business partners. As such,
there can be no assurance that our business will not be negatively affected by
Year 2000 problems experienced by these business partners.

RISKS RELATED TO THIS OFFERING

CHANGES IN REVENUE AND OPERATING RESULTS MAY CAUSE THE MARKET PRICE OF OUR STOCK
TO FLUCTUATE, WHICH MAY ADVERSELY AFFECT OUR ABILITY TO RAISE ADDITIONAL
CAPITAL.

         Due to the relatively high sales price of our products and low sales
unit volume, minor timing differences in receipt of customer orders have
produced and could continue to produce significant fluctuations in quarterly
results. In addition, if anticipated sales and shipments in any quarter do not
occur when expected, expenditures and inventory levels could be
disproportionately high, and our operating results for that quarter, and
potentially for future quarters, would be adversely affected. Quarterly results
may also fluctuate based on a variety of other factors. The important factors
which may cause our quarterly results to fluctuate are seasonality and
production delays. During the past four fiscal quarters, our net loss has
fluctuated from a low of $2.1 million to a high of $12.9 million. Such
fluctuations may cause our stock price to decline and adversely affect our
ability to raise additional capital.

THE VOLATILITY OF OUR STOCK PRICE MAKES THESE SECURITIES RISKY FOR THOSE SEEKING
A STABLE INVESTMENT.

         The market price of our common stock is very volatile, and our common
stock therefore may not be a suitable investment for those who seek stable
investment prices over the short or long term. Our common stock was first
publicly traded in December 1994 and has had last reported closing sale prices
ranging from a low of $1.38 per share in August 1999 to a high of $14.00 per
share in May 1997. The market price of our common stock could continue to
fluctuate substantially due to a variety of risk factors, including those
described elsewhere in this prospectus. The market price for our common stock
may also be affected by our ability to meet analysts' expectations. Any failure
to meet these expectations, even slightly, could have an adverse effect on the
market price of our common stock. In addition, the market prices of securities
issued by many companies may change for reasons unrelated to the operating
performance of these companies. In the past, following periods of volatility in
the market price of a company's securities, securities class action litigation
has often been instituted against the company. If similar litigation were
instituted against us, it could result in substantial costs and a diversion of
our management's attention and resources, which could have an adverse effect on
our business, results of operations and financial condition.

<PAGE>

A SIGNIFICANT NUMBER OF SHARES ARE ELIGIBLE FOR SALE, AND IF SOLD, THESE SHARES
MAY CREATE EXCESS SUPPLY IN THE MARKET CAUSING OUR STOCK PRICE TO DECLINE.

         Sales of a substantial number of our shares of common stock in the
public market could adversely affect the market price for our common stock. At
this time, approximately 7.6 million shares of our common stock are issuable
upon the full exercise of our outstanding Class B Warrants, and over 7.4 million
shares of our common stock are issuable upon exercise of other outstanding
warrants and options and conversion of outstanding debentures. The existence of
these outstanding warrants and options could adversely affect our ability to
obtain future financing. We have also reserved 2,250,000 shares of our common
stock for issuance in connection with the proposed settlement of outstanding
litigation. The consummation of this settlement will require satisfaction of a
number of conditions, and we cannot assure you that the settlement will be
completed.

         The price which we may receive for our common stock issued upon
exercise of outstanding options and warrants will likely be less than the market
price of our common stock at the time these options and warrants are exercised.
Moreover, the holders of the options and warrants might be expected to exercise
them at a time when we would, in all likelihood, be able to obtain needed
capital by a new offering of our securities on terms more favorable than those
provided for by the options and warrants.

OUR PREFERRED STOCK MAY DELAY OR PREVENT A TAKEOVER OF OUR COMPANY POSSIBLY
PREVENTING YOU FROM OBTAINING HIGHER SHARE PRICES.

         Our articles of incorporation authorize the issuance of 8,850,000
shares of "blank check" preferred stock, which will have terms as may be
determined from time to time by the board of directors. Accordingly, the board
of directors is empowered, without shareholder approval, to issue preferred
stock with terms which could adversely affect the rights of the holders of the
common stock. The preferred stock could also be utilized, under certain
circumstances, as a method of discouraging, delaying or preventing a change in
control of Premier. This could have the effect of preventing others from seeking
to acquire your shares in transactions at premium prices.

         In March 1998, we adopted a Shareholder Rights Plan, which entitles
certain of our shareholders to purchase our Series A Junior Participating
Preferred Stock. These rights are not exercisable until the acquisition by a
person or affiliated group of 15% or more of the outstanding shares of our
common stock, or the commencement or announcement of a tender offer or exchange
offer which would result in the acquisition of 15% or more of our outstanding
shares. Upon request, we will provide you with a copy of the Shareholder Rights
Plan. The Shareholder Rights Plan may have the effect of discouraging, delaying
or preventing a change of control of Premier.

SHORT SELLING OF OUR COMMON STOCK COULD ADVERSELY AFFECT OUR STOCK PRICE.

         If a significant number of shares of common stock which are issued upon
conversion of the debentures and payment of interest thereon are then sold in
the market, the price of our common stock could be depressed due to the presence
of these additional shares in the market. This downward pressure could encourage
short sales of common stock by the selling shareholders or others. By increasing
the number of shares offered for sale, material amounts of short selling could
place further downward pressure on the market price of the common stock.

                              ABOUT THIS PROSPECTUS

         This Prospectus is part of a Registration Statement we filed with the
Securities and Exchange Commission (the "SEC"). You should rely only on the
information incorporated by reference or provided in this Prospectus. We have
not authorized anyone else to provide you with different information. The
Registered Securityholders will not make an offer of the shares in any state
where the offer is not permitted. You should not assume that the information in
this Prospectus is accurate as of any date other than the date on the front of
the document.


                                 USE OF PROCEEDS

         The Registered Securityholders will directly receive the proceeds from
the sale of the shares. We will not receive any proceeds from the sale of the
shares offered by this Prospectus.


                                    DILUTION


         The following discussion and table treats our Class A Common Stock,
Class E-1 Common Stock and Class E-2 Common Stock as a single class.

         As of September 30, 1999, we had a net tangible book value of
$(2,600,000), or $(0.15) per share of common stock. Net tangible book value per
share represents the amount of total tangible assets less the amount of our
total liabilities, divided by the number of shares of common stock outstanding.
After giving effect to the issuance and conversion of the debentures and
exercise of the warrants, our adjusted pro forma net tangible book value as of
September 30, 1999 would have been $(1,317,000), or $(0.07) per share of common
stock. This amount represents an immediate increase in pro forma net tangible
book value of $0.08 per share to our existing shareholders and an immediate
dilution to the persons converting the debentures and exercising the warrants of
approximately $1.57 per share. Dilution is determined by subtracting pro forma
net tangible book value per share of common stock after this offering from the
price paid by new investors for a share of our common stock. The following table
illustrates this dilution on a per share basis and assume that all of the
warrants will be exercised:

(1)      The debentures are convertible into common stock based on the closing
         sale price of the common stock on the day the debenture is converted.
         Accordingly, the conversion price for the debentures will fluctuate on
         a daily basis. For purposes of this dilution table, we have assumed a
         conversion price of $1.50 per share and, based on such assumed price,
         the outstanding debentures would be convertible into approximately
         862,667 shares of common stock. The assumed average price per share
         equals the total amount that would be received upon conversion of the
         debentures and exercise of the warrants, divided by this assumed number
         of shares into which the debentures would have been convertible plus
         the number of shares issuable upon exercise of the warrants.

(1)      Beneficial ownership is determined in accordance with the rules of the
         SEC and generally includes voting or investment power with respect to
         securities. All of the securities being registered consist of shares of
         Class A Common Stock. The number of shares of common stock issuable
         upon conversion of the debentures is calculated by dividing the amount
         of the debenture by the closing sale price of the common stock on the
         day before the debenture is converted. For purposes of this Prospectus
         and the Registration Statement, we have assumed a closing sale price of
         $1.50 per share. For each of the Registered Securityholders, the number
         of shares of common stock beneficially owned and being offered under
         the Prospectus represents the number of shares of our common stock
         issuable upon conversion of convertible debentures within 60 days.
(2)      Assumes that all of the shares are sold pursuant to this Prospectus.

         Other than broker discounts and commissions, if any, we have agreed to
pay the expenses in connection with this Prospectus.

                              PLAN OF DISTRIBUTION

         The Registered Securityholders have advised us that they will offer for
sale, from time to time, all or a portion of the shares offered by this
Prospectus in one or more private or negotiated transactions, in open market
transactions on the Nasdaq National Market, in settlement of short sale
transactions, in settlement of option transactions, or otherwise, or a
combination of these methods, at prices and terms then obtainable, at fixed
prices, at prices then prevailing at the time of sale, at prices related to such
prevailing prices, or at negotiated prices or otherwise. The Registered
Securityholders may effect these transactions by selling the shares (i) to or
through underwriters; (ii) through broker-dealers or agents, which may include
underwriters, including: (a) in a block trade in which the broker or dealer so
engaged will attempt to sell the shares of common stock as agent, but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) in purchases by a broker or dealer and resale by such broker or
dealer as a principal for its account pursuant to this Prospectus; (c) in
ordinary brokerage transactions and (d) in transactions in which the broker
solicits purchasers; or (iii) directly to one or more purchasers. THE REGISTERED
SECURITYHOLDERS AND ANY UNDERWRITERS, DEALERS, BROKERS OR AGENTS EXECUTING
SELLING ORDERS ON BEHALF OF THE REGISTERED SECURITYHOLDERS MAY BE DEEMED TO BE
"UNDERWRITERS" WITHIN THE MEANING OF THE SECURITIES ACT AND ANY PROFITS ON THE
SALE OF THE SHARES BY THEM AND ANY DISCOUNTS, COMMISSIONS OR CONCESSIONS
RECEIVED BY SUCH UNDERWRITERS, DEALERS, BROKERS OR AGENTS MAY BE DEEMED TO BE
UNDERWRITING DISCOUNTS AND COMMISSIONS UNDER THE SECURITIES ACT. The
compensation to a particular underwriter, broker-dealer or agent may be in
excess of customary commissions. To our knowledge, the Registered
Securityholders have made no arrangement with any brokerage firm for the sale of
the shares.

         Any broker-dealer participating in such transactions as agent may
receive commissions from the Registered Securityholders and, if they act as
agent for the purchaser of such shares, from such purchaser. Broker-dealers may
agree with the Registered Securityholders to sell a specified number of shares
at a stipulated price per share and, to the extent such a broker-dealer is
unable to do so acting as agent for the Registered Securityholder, to purchase
as principal any unsold shares at the price required to fulfill the
broker-dealer commitment to the Registered Securityholder. Broker-dealers who
acquire shares as principal may thereafter resell such shares from time to time
in transactions, which may involve crosses and block transactions and which may
involve sales to and through other broker-dealers, including transactions of the
nature described above, in the over-the-counter market, in negotiated
transactions or otherwise at market prices prevailing at the time of sale or at
negotiated prices, and in connection with such resales may pay to or receive
from the purchasers of such shares commissions computed as described above. To
the extent required under the Securities Act, a supplemental prospectus will be
filed, disclosing (a) the name of any such broker-dealers; (b) the number of
shares involved; (c) the price at which such shares are to be sold; (d) the
commissions paid or discounts or concessions allowed to such broker-dealers,
where applicable; (e) that such broker-dealers did not conduct any investigation
to verify the information set out or incorporated by reference in this
Prospectus, as supplemented; and (f) other facts material to the transaction.

         The Registered Securityholders will act independently from Premier in
making decisions concerning the sale of the shares, provided, however, that
Premier and each of the Registered Securityholders have agreed to a maximum
value of shares of common stock that each Registered Securityholder may sell in
any calendar month.

                                       12
<PAGE>

         Under applicable rules and regulations under the Securities Exchange
Act of 1934, as amended, any person engaged in a distribution of the shares may
not simultaneously engage in market making activities with respect to the shares
for a period beginning when such person becomes a distribution participant and
ending upon such person's completion of participation in the distribution,
including stabilization activities in the common stock to effect covering
transactions, to impose penalty bids or to effect passive marketing making bids.
In addition to and without limiting the foregoing, in connection with
transactions in the shares, the Registered Securityholders and any underwriters,
dealers, brokers or agents executing selling orders on behalf of the Registered
Securityholders may be subject to applicable provisions of the Securities
Exchange Act of 1934,as amended, and the rules and regulations thereunder,
including, without limitation, Rule 10b-5 thereof and, insofar as Premier and
the Registered Securityholders are distribution participants, Regulation M and
Rules 100, 101, 102, 103, 104 and 105 thereof. All of the foregoing may affect
the marketability of the shares.

         The Registered Securityholders will pay all commissions, transfer taxes
and other expenses associated with their sales of the shares. The shares offered
hereby are being registered pursuant to our contractual obligations, and we have
agreed to pay the expenses of the preparation of this Prospectus and the filing
of the Registration Statement. We have also agreed to indemnify certain
Registered Securityholders against certain liabilities, including, without
limitation, liabilities arising under the Securities Act. We will not receive
any of the proceeds from the sale of the shares by the Registered
Securityholders.

         Total expenses incurred in connection with the preparation of this
Prospectus, consisting primarily of legal, accounting, and filing fees, are
estimated to be approximately $10,900.

         In order to comply with the securities laws of certain states, if
applicable, the shares may be sold in these jurisdictions only through
registered or licensed brokers or dealers. In addition, in certain states the
shares may not be sold unless the shares have been registered or qualified for
sale in these states or an exemption from registration or qualification is
available and complied with.

         Our common stock is currently traded on the Nasdaq National Market
under the symbol "PLSIA." Concurrently with sales under this Prospectus, the
Registered Securityholders may effect other sales of shares under Rule 144 or
other exempt resale transactions. There can be no assurance that the Registered
Securityholders, or any of them, will sell any or all of the shares offered
hereunder.


                      DESCRIPTION OF CONVERTIBLE DEBENTURES

         The securities being offered by the Registered Securityholders consist
of shares of our Class A Common Stock which are issuable upon the conversion of
convertible debentures. We are not required to pay interest on the principal sum
of the debentures.

         The debentures are convertible, at the option of the holder, into
shares of our Class A Common Stock at any time and from time to time from the
date they were issued. In addition, under certain circumstances, we may require
the Registered Securityholders to convert their debentures into shares of common
stock. The number of shares of our common stock issuable upon conversion is

                                       13
<PAGE>

determined by dividing the outstanding principal amount of the debenture to be
converted by the closing sale price of the common stock on the date the
conversion is to be effective, which date may not be prior to the date the
notice of conversion is deemed to have been delivered to us under the terms of
the debenture agreement. However, under certain circumstances the conversion
price may not be less than $1.50. Notwithstanding the foregoing, we may not
issue upon conversion a number of shares that exceeds 19.999% of the number of
shares of common stock outstanding immediately prior to the issuance of the
debenture, unless the common stock is then listed for trading on the Nasdaq or
the Nasdaq SmallCap Market and we have obtained shareholder approval for such
issuance.

         Since the number of shares of common stock issuable upon conversion of
the debentures is dependent in part upon the market price of the common stock
prior to the conversion, the actual number of shares of common stock that will
then be issued in respect of such conversions and, consequently, offered for
sale pursuant to this Prospectus, cannot be determined at this time. Therefore,
for purposes of this Prospectus, we have assumed a conversion rate of $1.50 per
share and, therefore, based upon an aggregate principal amount of the debentures
of $1,294,000, we are registering an aggregate of 862,667 shares of our common
stock.

         Each of the Registered Securityholders has agreed to a maximum value of
shares of common stock that each Registered Securityholder may sell in any
calendar month.


                                  LEGAL MATTERS

         The validity of the shares offered pursuant to this Prospectus will be
passed upon for us by Rutan & Tucker, LLP, Costa Mesa, California. As of
December 3, 1999, Rutan & Tucker, LLP held convertible debentures issued by
Premier in the aggregate amount of $211,000. Based upon an assumed closing sale
price of our common stock of $1.50 per share, such debentures would be
convertible into approximately 140,667 shares of our common stock, and Rutan &
Tucker, LLP would be deemed to beneficially own approximately 140,667 shares of
our common stock.

                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The California General Corporations Law provides that California
corporations may include provisions in their articles of incorporation relieving
directors of monetary liability for breach of their fiduciary duty as directors,
except for the liability of a director resulting from (i) any transaction from
which the director derives an improper personal benefit, (ii) acts or omissions
involving intentional misconduct or a knowing and culpable violation of law,
(iii) acts or omissions that a director believes to be contrary to the best
interests of the registrant or its shareholders or that involves the absence of
good faith on the part of the director, (iv) acts or omissions constituting an
unexcused pattern of inattention that amounts to an abdication of the director's
duty to the registrant or its shareholders, (v) acts or omissions showing a
reckless disregard for the director's duty to the registrant or its shareholders
in circumstances in which the director was aware or should have been aware, in
the ordinary course of performing a director's duties, of a risk of serious
injury to the registrant or its shareholders, (vi) any improper transaction
between a director and the registrant in which the director has a material
financial interest, or (vii) the making of an illegal distribution to
shareholders or an illegal loan or guaranty. Our Articles of Incorporation
provide that our directors are not liable to us or our shareholders for monetary
damages for breach of their fiduciary duties to the fullest extent permitted by
California law.

         The inclusion of the above provision in the Articles of Incorporation
may have the effect of reducing the likelihood of derivative litigation against
directors and may discourage or deter shareholders or management from bringing a
lawsuit against directors for breach of their duty of care, even though such an
action, if successful, might otherwise have benefitted us and our shareholders.

         Our Articles of Incorporation and bylaws provide that we will indemnify
our directors and officers to the fullest extent permitted by California law,
including circumstances in which indemnification is otherwise discretionary
under California law. Since the California statute is nonexclusive, it is
possible that certain claims beyond the scope of the statute may be
indemnifiable. Accordingly, we have also entered into an indemnification
agreement (the "Indemnification Agreement") with certain of our directors and
officers that requires us to indemnify such directors and officers to the
fullest extent permitted by law.

         Set forth below is a description of the principal provisions of the
Indemnification Agreement:

         First, the Indemnification Agreement imposes upon us the burden of
proving that the indemnified party has not met the applicable standard of
conduct required for indemnification. The California statute requires a finding
by the Board of Directors, independent legal counsel, or the shareholders that
the applicable standard of conduct has been met.

         Second, the Indemnification Agreement provides that litigation expenses
shall be advanced to an indemnified party at his request, against an undertaking
to repay the amount advanced if it is ultimately determined that he is not
entitled to indemnification for such expenses. The California statute provides
that such expenses may be advanced against such an undertaking, upon
authorization by the Board of Directors.

                                       16
<PAGE>

         Third, in the event we do not pay a requested indemnification amount,
the Indemnification Agreement allows such indemnified party to contest this
determination by petitioning a court to make an independent determination of
whether such indemnified party is entitled to indemnification under the
Indemnification Agreement. The California statute does not set forth the
procedure for contesting a corporation's determination of a party's right to
indemnification.

         Finally, the Indemnification Agreement explicitly provides that actions
by an Indemnified Party at our request as a director, officer or agent of an
employee benefit plan, corporation, partnership, joint venture or other
enterprise owned or controlled by us shall be covered by the indemnification.
The California statute does not specifically address this issue. It does,
however, provide that to the extent that an indemnified party has been
successful on the merits, he shall be entitled to such indemnification.

         We are currently engaged in class action litigation in which certain
current and former directors are seeking indemnification, and for which we have
agreed to provide indemnification.

         We are also empowered under our bylaws to purchase insurance on behalf
of any person we are required or permitted to indemnify.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers or controlling persons pursuant to
the foregoing provisions, or otherwise, Premier has been advised that in the
opinion of the Securities and Exchange Commission, such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The California General Corporations Law provides that California
corporations may include provisions in their articles of incorporation relieving
directors of monetary liability for breach of their fiduciary duty as directors,
except for the liability of a director resulting from (i) any transaction from
which the director derives an improper personal benefit, (ii) acts or omissions
involving intentional misconduct or a knowing and culpable violation of law,
(iii) acts or omissions that a director believes to be contrary to the best
interests of the Registrant or its shareholders or that involves the absence of
good faith on the part of the director, (iv) acts or omissions constituting an
unexcused pattern of inattention that amounts to an abdication of the director's
duty to the Registrant or its shareholders, (v) acts or omissions showing a
reckless disregard for the director's duty to the Registrant or its shareholders
in circumstances in which the director was aware or should have been aware, in
the ordinary course of performing a director's duties, of a risk of serious
injury to the Registrant or its shareholders, (vi) any improper transaction
between a director and the Registrant in which the director has a material
financial interest, or (vii) the making of an illegal distribution to
shareholders or an illegal loan or guaranty. The Registrant's Articles of
Incorporation provide that the Registrant's directors are not liable to the
Registrant or its shareholders for monetary damages for breach of their
fiduciary duties to the fullest extent permitted by California law.

         The inclusion of the above provision in the Articles of Incorporation
may have the effect of reducing the likelihood of derivative litigation against
directors and may discourage or deter shareholders or management from bringing a
lawsuit against directors for breach of their duty of care, even though such an
action, if successful, might otherwise have benefitted the Registrant and its
shareholders.

         The Registrant's Articles of Incorporation and bylaws provide that the
Registrant shall indemnify its directors and officers to the fullest extent

(a)      The undersigned Registrant hereby undertakes:

         (1)      To file, during any period in which offers or sales are being
                  made, a post-effective amendment to this registration
                  statement:

                  (i)      To include any prospectus required by Section
                           10(a)(3) of the Securities Act;

                  (ii)     To reflect in the prospectus any facts or events
                           arising after the effective date of the Registration
                           Statement (or the most recent post-effective
                           amendment thereof) which, individually or in the
                           aggregate, represent a fundamental change in the
                           information set forth in the Registration Statement.
                           Notwithstanding the foregoing, any increase or
                           decrease in volume of securities offered (if the
                           total value of securities offered would not exceed
                           that which was registered) and any deviation from the
                           low or high end of the estimated maximum offering
                           range may be reflected in the form of prospectus
                           filed with the SEC pursuant to Rule 424(b) if, in the
                           aggregate, the changes in volume and price present no
                           more than a 20% change in the maximum aggregate
                           offering price set forth in the "Calculation of
                           Registration Fee" table in the effective Registration
                           Statement;

                  (iii)    To include any material information with respect to
                           the plan of distribution not previously disclosed in

         PROVIDED, HOWEVER, that paragraphs (1)(i) and (1)(ii) do not apply if
         the information required to be included in a post-effective amendment
         by those paragraphs is contained in periodic reports filed with or
         furnished to the SEC by the Registrant pursuant to Section 13 or
         Section 15(d) of the Securities of 1934, as amended, that are
         incorporated by reference in the Registration Statement.

         (2)      That, for the purpose of determining any liability under the
                  Securities Act, each such post-effective amendment shall be
                  deemed to be a new registration statement relating to the
                  securities offered therein, and the offering of such
                  securities at that time shall be deemed to be the initial BONA
                  FIDE offering thereof.

         (3)      To remove from registration by means of a post-effective
                  amendment any of the securities being registered which remain
                  unsold at the termination of the offering.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
of 1934, as amended (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at the time shall be deemed to be
the initial BONA FIDE offering thereof.

         The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the

amended; and, where interim financial information requires to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

resale of the Common Stock into which this Debenture is convertible, but no

representations of the Holder set forth in a separate agreement being entered
into concurrently with this Debenture, and may be transferred or exchanged only
in compliance with applicable securities laws. Prior to due presentment to the
Company for transfer of this Debenture, the Company and any agent of the Company

                  in any of the foregoing; or any corporate or other action is
                  taken by the Company or any subsidiary thereof for the purpose
                  of effecting any of the foregoing;

                           (iv) the Common Stock shall be either delisted from
                  the NASDAQ or suspended from trading on the NASDAQ without
                  resuming trading and/or being relisted thereon or on a

                  (5) consecutive Trading Days or eight (8) Trading Days in the
                  aggregate (which need not be consecutive days);

                           (v) the Company shall fail for any reason to deliver
                  certificates to a Holder prior to the twelfth (12th) day after
                  a Conversion Date pursuant to and in accordance with Section
                  4(b) or the Company shall provide notice to the Holder,
                  including by way of public announcement, at any time, of its

                  Debentures in accordance with the terms hereof;

                                        2
<PAGE>

                  (b) If any Event of Default occurs and is continuing, the full
         principal amount of this Debenture (and, at the Holder's option, all
         other Debentures then held by such Holder), together with other amounts
         owing in respect thereof, to the date of acceleration shall become,
         immediately due and payable in cash. The aggregate amount payable upon
         an Event of Default shall be equal to the entire unpaid principal
         amount of this Debenture. The Holder need not provide and the Company
         hereby waives any presentment, demand, protest or other notice of any
         kind, and the Holder may immediately and without expiration of any
         grace period enforce any and all of its rights and remedies hereunder
         and all other remedies available to it under applicable law. Such
         declaration may be rescinded and annulled by Holder at any time prior
         to payment hereunder. No such rescission or annulment shall affect any
         subsequent Event of Default or impair any right consequent thereon.

                  (c) If the Company has not registered the resale by Holder of
         the Common Stock into which this Debenture is convertible under the
         Securities Act of 1933, as amended, on or prior to that date ninety
         (90) days from the date of this Debenture, the Holder will have the
         option to require the Company to immediately repay upon expiration of
         such ninety (90) day period or refusal of registration by the SEC,
         whichever is earlier, the outstanding principal balance of the
         Debentures in monthly installments. Such payments will be made
         retroactively to July 1, 1999, with the first monthly payment being
         [Monthly Amount] and the remainder being [Monthly Amount] per month,
         i.e., the amounts for monthly payments between July 1, 1999 and the
         date of such obligation to pay the outstanding balance in monthly
         installments shall be immediately due and payable with the remainder of
         such payments to be made on the first of the following months until the
         principal balance of the Debentures has been fully paid.

         SECTION 4. CONVERSION.

                  (a) (i) CONVERSION AT OPTION OF HOLDER. This Debenture shall
                  be convertible into shares of Common Stock at the option of
                  the Holder, in whole or in part at any time and from time to
                  time, after the Original Issue Date (subject to the
                  limitations on conversion set forth in Section 4(a)(ii)
                  hereof). The number of shares of Common Stock issuable upon a
                  conversion hereunder shall be determined by dividing the
                  outstanding principal amount of this Debenture to be
                  converted, by the Conversion Price. The Holder shall effect
                  conversions by surrendering the Debentures (or such portions
                  thereof) to be converted, together with the form of conversion
                  notice attached hereto as EXHIBIT A (a "CONVERSION NOTICE") to
                  the Company. Each Conversion Notice shall specify the
                  principal amount of Debentures to be converted and the date on
                  which such conversion is to be effected, which date may not be
                  prior to the date such Conversion Notice is deemed to have
                  been delivered hereunder (a "CONVERSION DATE"). If no
                  Conversion Date is specified in a Conversion Notice, the
                  Conversion Date shall be the date that such Conversion Notice
                  is deemed delivered hereunder. Subject to Section 4(b), each
                  Conversion Notice, once given, shall be irrevocable. If the
                  Holder is converting less than all of the principal amount
                  represented by the Debenture(s) tendered by the Holder with
                  the Conversion Notice, or if a conversion hereunder cannot be
                  effected in full for any reason, the Company shall honor such
                  conversion to the extent permissible hereunder and shall
                  promptly deliver to such Holder (in the manner and within the
                  time set forth in Section 4(b)) a new Debenture for such
                  principal amount as has not been converted.

                      (ii) CERTAIN CONVERSION RESTRICTIONS

                               (A) If the Common Stock is then listed for
                           trading on the NASDAQ or the Nasdaq SmallCap Market
                           and the Company has not obtained the Shareholder
                           Approval (as defined below), then the Company may not
                           issue in excess of 3,184,676 shares of Common Stock
                           upon conversions of Debentures or as payment of
                           interest thereon in shares of Common Stock, which
                           number shall be subject to adjustment pursuant to
                           Sections 4(c)(ii), (iii), (v), (vi) and (x) (such
                           number of shares, the "ISSUABLE MAXIMUM"). The
                           Issuable Maximum equals 19.999% of the number of
                           shares of Common Stock outstanding immediately prior
                           to the issuance of this Debenture. If on any
                           Conversion Date (A) the Common Stock is listed for
                           trading on the NASDAQ or the Nasdaq SmallCap Market,
                           (B) the Conversion Price then in effect is such that
                           the aggregate number of shares of Common Stock that
                           would then be issuable upon conversion in full of all
                           then outstanding Debentures held by Holder, together
                           with any shares of Common Stock previously issued
                           upon conversion of Debentures would exceed the
                           Issuable Maximum, and (C) the Company shall not have
                           previously obtained any vote of shareholders that may
                           be required by the applicable rules and regulations
                           of the Nasdaq Stock Market (or any successor entity)
                           applicable to approve the issuance of shares of
                           Common Stock in excess of the Issuable Maximum
                           pursuant to the terms hereof (the "SHAREHOLDER
                           APPROVAL"), then the Company shall issue to the
                           Holder requesting a conversion a number of shares of
                           Common Stock equal to the Issuable Maximum and, with
                           respect to the remainder of the principal amount of
                           Debentures then held by such Holder for which a
                           conversion in accordance with the Conversion Price
                           would result in an issuance of shares of Common Stock
                           in excess of the Issuable Maximum (the "EXCESS
                           PRINCIPAL"), the converting Holder shall have the
                           option to require the Company to pay cash to the
                           converting Holder in an amount equal to the
                           Conversion Price for all shares of Common Stock
                           constituting the Excess Principal (the "MANDATORY
                           PREPAYMENT AMOUNT"). If the Company fails to pay the
                           Mandatory Prepayment Amount in full pursuant to this
                           Section, the Company will pay interest thereon at a
                           rate of 15% per annum to the converting Holder,
                           accruing daily from the Conversion Date until such
                           amount, plus all such interest thereon, is paid in
                           full.

                  (b) (i) Not later than three (3) Trading Days after any
                  Conversion Date, the Company will deliver to the Holder (i) a
                  certificate or certificates which shall be free of restrictive
                  legends and trading restrictions (other than those required
                  under applicable securities laws) representing the number of
                  shares of Common Stock being acquired upon the conversion of
                  Debentures (subject to the limitations set forth in Section
                  4(a)(ii) hereof), and (ii) Debentures in a principal amount
                  equal to the principal amount of Debentures not converted;
                  PROVIDED, that the Company shall not be obligated to issue
                  certificates evidencing the shares of Common Stock issuable
                  upon conversion of the principal amount of Debentures until
                  Debentures are delivered for conversion to the Company, or the
                  Holder notifies the Company that such Debentures have been
                  lost, stolen or destroyed and provides a bond (or other
                  adequate security) reasonably satisfactory to the Company to
                  indemnify the Company from any loss incurred by it in
                  connection therewith. The Company shall, upon request of the
                  Holder, if available, use its best efforts to deliver any
                  certificate or certificates required to be delivered by the
                  Company under this Section electronically through the

                                        4

<PAGE>

                  Depository Trust Corporation or another established clearing
                  corporation performing similar functions. If in the case of
                  any Conversion Notice such certificate or certificates are not
                  delivered to or as directed by the applicable Holder by the
                  third (3rd) Trading Day after the Conversion Date, the Holder
                  shall be entitled by written notice to the Company at any time
                  on or before its receipt of such certificate or certificates
                  thereafter, to rescind such conversion, in which event the
                  Company shall immediately return the certificates representing
                  the principal amount of Debentures tendered for conversion.

                      (ii) If the Company fails to deliver to the Holder
                  such certificate or certificates pursuant to Section 4(b)(i),
                  by the third (3rd) Trading Day after the Conversion Date, the
                  Company shall pay to such Holder, in cash, as liquidated
                  damages and not as a penalty, $5,000 for each Trading Day
                  after such third (3rd) Trading Day until such certificates are
                  delivered. Nothing herein shall limit a Holder's right to
                  pursue actual damages for the Company's failure to deliver
                  certificates representing shares of Common Stock upon
                  conversion within the period specified herein and such Holder
                  shall have the right to pursue all remedies available to it at
                  law or in equity including, without limitation, a decree of
                  specific performance and/or injunctive relief. The exercise of
                  any such rights shall not prohibit the Holders from seeking to
                  enforce damages pursuant to any other Section hereof or under
                  applicable law. Further, if the Company shall not have
                  delivered any cash due in respect of conversions of Debentures
                  by the third (3rd) Trading Day after the Conversion Date, the
                  Holder may, by notice to the Company, require the Company to
                  issue shares of Common Stock pursuant to Section 4(c), except
                  that for such purpose the Conversion Price applicable thereto
                  shall be the lesser of the Conversion Price on the Conversion
                  Date and the Conversion Price on the date of such Holder
                  demand. Any such shares will be subject to the provision of
                  this Section.

                           (iii) In addition to any other rights available to
                  the Holder, if the Company fails to deliver to the Holder such
                  certificate or certificates pursuant to Section 4(b)(i), by
                  the third (3rd) Trading Day after the Conversion Date, and if
                  after such third (3rd) Trading Day the Holder purchases (in an
                  open market transaction or otherwise) Common Stock to deliver
                  in satisfaction of a sale by such Holder of the Underlying
                  Shares which the Holder anticipated receiving upon such
                  conversion (a "BUY-IN"), then the Company shall (A) pay in
                  cash to the Holder (in addition to any remedies available to
                  or elected by the Holder) the amount by which (x) the Holder's
                  total purchase price (including brokerage commissions, if any)
                  for the Common Stock so purchased exceeds (y) the product of
                  (1) the aggregate number of shares of Common Stock that such
                  Holder anticipated receiving from the conversion at issue
                  multiplied by (2) the market price of the Common Stock at the
                  time of the sale giving rise to such purchase obligation and
                  (B) at the option of the Holder, either reissue Debentures in
                  principal amount equal the principal amount of the attempted
                  conversion or deliver to the Holder the number of shares of
                  Common Stock that would have been issued had the Company
                  timely complied with its delivery requirements under Section
                  4(b)(i). For example, if the Holder purchases Common Stock
                  having a total purchase price of $11,000 to cover a Buy-In
                  with respect to an attempted conversion of Debentures with
                  respect to which the market price of the Underlying Shares on
                  the date of conversion was a total of $10,000 under clause (A)
                  of the immediately preceding sentence, the Company shall be
                  required to pay the Holder $1,000. The Holder shall provide
                  the Company written notice indicating the amounts payable to
                  the Holder in respect of the Buy-In. Notwithstanding anything
                  contained herein to the contrary, if a Holder requires the

                                        5
<PAGE>

                  Company to make payment in respect of a Buy- In for the
                  failure to timely deliver certificates hereunder and the
                  Company timely pays in full such payment, the Company shall
                  not be required to pay such Holder liquidated damages under
                  Section 4(b)(ii) in respect of the certificates resulting in
                  such Buy-In.

                  (c)      (i) The conversion price (the "CONVERSION PRICE") in
                  effect on any Conversion Date shall be the closing sale price
                  of the Common Stock on the Conversion Date which must be a
                  Trading Day. Notwithstanding the foregoing, the Conversion
                  Price shall not be less than the Floor (as defined in Section
                  7) for so long as the Floor remains in effect in accordance
                  with Section 6; PROVIDED, that the Floor shall be subject to
                  reduction due to operation of this Section 4(c).

                           (ii) In case of any reclassification of the Common
                  Stock or any compulsory share exchange pursuant to which the
                  Common Stock is converted into other securities, cash or
                  property, the Holders shall have the right thereafter to, at
                  their option, (A) convert the then outstanding principal
                  amount only into the shares of stock and other securities,
                  cash and property receivable upon or deemed to be held by
                  holders of the Common Stock following such reclassification or
                  share exchange, and the Holders of the Debentures shall be
                  entitled upon such event to receive such amount of securities,
                  cash or property as the shares of the Common Stock of the
                  Company into which the then outstanding principal amount could
                  have been converted immediately prior to such reclassification
                  or share exchange would have been entitled or (B) require the
                  Company to prepay the aggregate of its outstanding principal
                  amount of Debentures. The entire prepayment price shall be
                  paid in cash. This provision shall similarly apply to
                  successive reclassifications or share exchanges.

                           (iii) All calculations under this Section 4 shall be
                  made to the nearest cent or the nearest 1/100th of a share, as
                  the case may be.

                           (iv) If (A) the Company shall declare a special
                  nonrecurring cash dividend on or a redemption of the Common
                  Stock; (B) the Company shall authorize the granting to all
                  holders of the Common Stock rights or warrants to subscribe
                  for or purchase any shares of capital stock of any class or of
                  any rights; (C) the approval of any stockholders of the
                  Company shall be required in connection with any
                  reclassification of the Common Stock, any consolidation or
                  merger to which the Company is a party, any sale or transfer
                  of all or substantially all of the assets of the Company, of
                  any compulsory share exchange whereby the Common Stock is
                  converted into other securities, cash or property; (D) the
                  Company shall authorize the voluntary or involuntary
                  dissolution, liquidation or winding up of the affairs of the
                  Company; then, in each case, the Company shall give notice to
                  the Holders as provided in subsection (g) below at least 20
                  calendar days prior to the applicable record or effective date
                  hereinafter specified, a notice stating (x) the date on which
                  a record is to be taken for the purpose of such dividend,
                  distribution, redemption, rights or warrants, or if a record
                  is not to be taken, the date as of which the holders of the
                  Common Stock of record to be entitled to such dividend,
                  distributions, redemption, rights or warrants are to be
                  determined or (y) the date on which such reclassification,
                  consolidation, merger, sale, transfer or share exchange is
                  expected to become effective or close, and the date as of
                  which it is expected that holders of the Common Stock of
                  record shall be entitled to exchange their shares of the
                  Common Stock for securities, cash or other property
                  deliverable upon such reclassification, consolidation, merger,
                  sale, transfer or share exchange; PROVIDED, HOWEVER, that the

                                        6
<PAGE>

                  failure to mail such notice or any defect therein or in the
                  mailing thereof shall not affect the validity of the corporate
                  action required to be specified in such notice. The failure to
                  provide such notice shall constitute an Event of Default under
                  Section 3(a)(ii) above unless the Holder is otherwise provided
                  the opportunity, upon conversion, to receive the dividend,
                  redemption rights, subscription rights or warrants, voting or
                  approval rights, securities or other consideration that would
                  be payable or provided to Holder had Holder converted the
                  Debentures into Common Stock prior to the consummation of any
                  of the actions or events identified in clauses (A) through (D)
                  above. Holders are entitled to convert Debentures during the
                  20-day period commencing the date of such notice to the
                  effective date of the event triggering such notice.

                           (v) In case of any (1) merger or consolidation of the
                  Company with or into another Person that would constitute a
                  Change of Control Transaction, or (2) sale by the Company of
                  more than one-half of the assets of the Company (on an as
                  valued basis) in one or a series of related transactions, or
                  (3) tender or other offer or exchange (whether by the Company
                  or another Person) pursuant to which holders of Common Stock
                  are permitted to tender or exchange their shares for other
                  securities, stock, cash or property of the Company or another
                  Person; then a Holder shall have the right to (A) convert its
                  aggregate principal amount of Debentures then outstanding into
                  the shares of stock and other securities, cash and property
                  receivable upon or deemed to be held by holders of Common
                  Stock following such merger, consolidation or sale, and such
                  Holder shall be entitled upon such event or series of related
                  events to receive such amount of securities, cash and property
                  as the shares of Common Stock into which such aggregate
                  principal amount of Debentures could have been converted
                  immediately prior to such merger, consolidation or sales would
                  have been entitled, (B) in the case of a merger or
                  consolidation, (x) require the surviving entity to issue
                  convertible debentures in a principal amount equal to the
                  aggregate principal amount of Debentures then held by such
                  Holder, which newly issued debentures shall have terms
                  identical (including with respect to conversion) to the terms
                  of this Debenture and shall be entitled to all of the rights
                  and privileges of a Holder of Debentures set forth herein, and
                  (y) simultaneously with the issuance of such convertible
                  debentures, shall have the right to convert such instrument
                  only into shares of stock and other securities, cash and
                  property receivable upon or deemed to be held by holders of
                  Common Stock following such merger or consolidation, or (C) in
                  the event of an exchange or tender offer or other transaction
                  contemplated by clause (3) of this Section, tender or exchange
                  its aggregate principal amount of Debentures for such
                  securities, stock, cash and other property receivable upon or
                  deemed to be held by holders of Common Stock that have
                  tendered or exchanged their shares of Common Stock following
                  such tender or exchange, and such Holder shall be entitled
                  upon such exchange or tender to receive such amount of
                  securities, cash and property as the shares of Common Stock
                  into which such aggregate principal amount of Debentures could
                  have been converted immediately prior to such tender or
                  exchange would have been entitled as would have been issued.
                  In the case of clause (B), the conversion price applicable for
                  the newly issued convertible debentures shall be based upon
                  the amount of securities, cash and property that each share of
                  Common Stock would receive in such transaction and the
                  Conversion Price in effect immediately prior to the
                  effectiveness or closing date for such transaction. The terms
                  of any such merger, sale, consolidation, tender or exchange
                  shall include such terms so as to continue to give the Holders
                  of Debentures the right to receive the securities, cash
                  and property set forth in this Section upon any conversion or
                  redemption following such event. This provision shall
                  similarly apply to successive such events.

                  (d) The Company covenants that it will at all times reserve
         and keep available out of its authorized and unissued shares of Common
         Stock solely for the purpose of issuance upon conversion of the
         Debentures, free from preemptive rights or any other actual contingent
         purchase rights of persons other than the Holders, not less than such
         number of shares of the Common Stock as shall be issuable (taking into
         account the adjustments and restrictions of Section 4(b)) upon the
         conversion of the outstanding principal amount of the Debentures and
         payment of interest hereunder. The Company covenants that all shares of
         Common Stock that shall be so issuable shall, upon issue, be duly and
         validly authorized, issued and fully paid, nonassessable and, if a
         Registration Statement has been declared effective under the Securities
         Act, registered for public sale in accordance with such Registration
         Statement.

                  (e) Upon a conversion hereunder the Company shall not be
         required to issue stock certificates representing fractions of shares
         of the Common Stock, but may if otherwise permitted, make a cash
         payment in respect of any final fraction of a share based on the market
         value of a share of Common Stock at such time. If the Company elects
         not, or is unable, to make such a cash payment, the Holder shall be
         entitled to receive, in lieu of the final fraction of a share, one
         whole share of Common Stock.

                  (f) The issuance of certificates for shares of the Common
         Stock on conversion of the Debentures shall be made without charge to
         the Holders thereof for any documentary stamp or similar taxes that may
         be payable in respect of the issue or delivery of such certificate,
         provided that the Company shall not be required to pay any tax that may
         be payable in respect of any transfer involved in the issuance and
         delivery of any such certificate upon conversion in a name other than
         that of the Holder of such Debentures so converted and the Company
         shall not be required to issue or deliver such certificates unless or
         until the person or persons requesting the issuance thereof shall have
         paid to the Company the amount of such tax or shall have established to

         owing in respect thereof, to the date of acceleration shall become,
         immediately due and payable in cash. The aggregate amount payable upon
         an Event of Default shall be equal to the entire unpaid principal
         amount of this Debenture. The Holder need not provide and the Company
         hereby waives any presentment, demand, protest or other notice of any
         kind, and the Holder may immediately and without expiration of any
         grace period enforce any and all of its rights and remedies hereunder
         and all other remedies available to it under applicable law. Such
         declaration may be rescinded and annulled by Holder at any time prior
         to payment hereunder. No such rescission or annulment shall affect any
         subsequent Event of Default or impair any right consequent thereon.

                  (c) If the Company has not registered the resale by Holder of
         the Common Stock into which this Debenture is convertible under the
         Securities Act of 1933, as amended, on or prior to that date ninety
         (90) days from the date of this Debenture, the Holder will have the
         option to require the Company to immediately repay upon expiration of
         such ninety (90) day period or refusal of registration by the SEC,
         whichever is earlier, the outstanding principal balance of the
         Debentures in monthly installments. Such payments will be made monthly
         commencing ____________, 2000, with each monthly payment being [MONTHLY
         AMOUNT] until the principal balance of the Debentures has been fully
         paid.

         SECTION 4. CONVERSION.

                  (a) (i) CONVERSION AT OPTION OF HOLDER. This Debenture shall
                  be convertible into shares of Common Stock at the option of
                  the Holder, in whole or in part at any time and from time to
                  time, after the Original Issue Date (subject to the
                  limitations on conversion set forth in Section 4(a)(ii)
                  hereof). The number of shares of Common Stock issuable upon a
                  conversion hereunder shall be determined by dividing the
                  outstanding principal amount of this Debenture to be
                  converted, by the Conversion Price. The Holder shall effect
                  conversions by surrendering the Debentures (or such portions
                  thereof) to be converted, together with the form of conversion
                  notice attached hereto as EXHIBIT A (a "CONVERSION NOTICE") to
                  the Company. Each Conversion Notice shall specify the
                  principal amount of Debentures to be converted and the date on
                  which such conversion is to be effected, which date may not be
                  prior to the date such Conversion Notice is deemed to have
                  been delivered hereunder (a "CONVERSION DATE"). If no
                  Conversion Date is specified in a Conversion Notice, the
                  Conversion Date shall be the date that such Conversion Notice
                  is deemed delivered hereunder. Subject to Section 4(b), each
                  Conversion Notice, once given, shall be irrevocable. If the
                  Holder is converting less than all of the principal amount
                  represented by the Debenture(s) tendered by the Holder with
                  the Conversion Notice, or if a conversion hereunder cannot be
                  effected in full for any reason, the Company shall honor such
                  conversion to the extent permissible hereunder and shall
                  promptly deliver to such Holder (in the manner and within the
                  time set forth in Section 4(b)) a new Debenture for such
                  principal amount as has not been converted.

                           (ii)     CERTAIN CONVERSION RESTRICTIONS

                                    (A) If the Common Stock is then listed for
                           trading on the NASDAQ or the Nasdaq SmallCap Market
                           and the Company has not obtained the Shareholder
                           Approval (as defined below), then the Company may not
                           issue in excess of ___________ shares of Common Stock
                           upon conversions of Debentures or as payment of
                           interest thereon in shares of Common Stock, which
                           number shall be subject to adjustment pursuant to
                           Sections 4(c)(ii), (iii), (v), (vi) and (x) (such
                           number of shares, the "ISSUABLE MAXIMUM"). The
                           Issuable Maximum equals 19.999% of the number of
                           shares of Common Stock outstanding immediately prior
                           to the issuance of this Debenture. If on any
                           Conversion Date (A) the Common Stock is listed for
                           trading on the NASDAQ or the Nasdaq SmallCap Market,
                           (B) the Conversion Price then in effect is such that
                           the aggregate number of shares of Common Stock that
                           would then be issuable upon conversion in full of all
                           then outstanding Debentures held by Holder, together
                           with any shares of Common Stock previously issued
                           upon conversion of Debentures would exceed the
                           Issuable Maximum, and (C) the Company shall not have
                           previously obtained any vote of shareholders that may
                           be required by the applicable rules and regulations
                           of the Nasdaq Stock Market (or any successor entity)
                           applicable to approve the issuance of shares of
                           Common Stock in excess of the Issuable Maximum
                           pursuant to the terms hereof (the "SHAREHOLDER
                           APPROVAL"), then the Company shall issue to the
                           Holder requesting a conversion a number of shares of
                           Common Stock equal to the Issuable Maximum and, with
                           respect to the remainder of the principal amount of
                           Debentures then held by such Holder for which a
                           conversion in accordance with the Conversion Price
                           would result in an issuance of shares of Common Stock
                           in excess of the Issuable Maximum (the "EXCESS
                           PRINCIPAL"), the converting Holder shall have the
                           option to require the Company to pay cash to the
                           converting Holder in an amount equal to the
                           Conversion Price for all shares of Common Stock
                           constituting the Excess Principal (the "MANDATORY
                           PREPAYMENT AMOUNT"). If the Company fails to pay the
                           Mandatory Prepayment Amount in full pursuant to this
                           Section, the Company will pay interest thereon at a
                           rate of 15% per annum to the converting Holder,
                           accruing daily from the Conversion Date until such
                           amount, plus all such interest thereon, is paid in
                           full.

                  (b)      (i) Not later than three (3) Trading Days after
                  any Conversion Date, the Company will deliver to the Holder
                  (i) a certificate or certificates which shall be free of
                  restrictive legends and trading restrictions (other than those
                  required under applicable securities laws) representing the
                  number of shares of Common Stock being acquired upon the
                  conversion of Debentures (subject to the limitations set forth
                  in Section 4(a)(ii) hereof), and (ii) Debentures in a
                  principal amount equal to the principal amount of Debentures
                  not converted; PROVIDED, that the Company shall not be
                  obligated to issue certificates evidencing the shares of
                  Common Stock issuable upon conversion of the principal amount
                  of Debentures until Debentures are delivered for conversion to
                  the Company, or the Holder notifies the Company that such
                  Debentures have been lost, stolen or destroyed and provides a
                  bond (or other adequate security) reasonably satisfactory to
                  the Company to indemnify the Company from any loss incurred by
                  it in connection therewith. The Company shall, upon request of
                  the Holder, if available, use its best efforts to deliver any
                  certificate or certificates required to be delivered by the
                  Company under this Section electronically through the
                  Depository Trust Corporation or another established clearing
                  corporation performing similar functions. If in the case of
                  any Conversion Notice such certificate or certificates are not
                  delivered to or as directed by the applicable Holder by the
                  third (3rd) Trading Day after the Conversion Date, the Holder
                  shall be entitled by written notice to the Company at any time
                  on or before its receipt of such certificate or certificates
                  thereafter, to rescind such conversion, in which event the
                  Company shall immediately return the certificates representing
                  the principal amount of Debentures tendered for conversion.

                           (ii) If the Company fails to deliver to the Holder
                  such certificate or certificates pursuant to Section 4(b)(i),
                  by the third (3rd) Trading Day after the Conversion Date, the
                  Company shall pay to such Holder, in cash, as liquidated
                  damages and not as a penalty, $1,000 for each Trading Day
                  after such third (3rd) Trading Day until such certificates are
                  delivered. Nothing herein shall limit a Holder's right to
                  pursue actual damages for the Company's failure to deliver
                  certificates representing shares of Common Stock upon
                  conversion within the period specified herein and such Holder
                  shall have the right to pursue all remedies available to it at
                  law or in equity including, without limitation, a decree of
                  specific performance and/or injunctive relief. The exercise of
                  any such rights shall not prohibit the Holders from seeking to
                  enforce damages pursuant to any other Section hereof or under
                  applicable law. Further, if the Company shall not have
                  delivered any cash due in respect of conversions of Debentures
                  by the third (3rd) Trading Day after the Conversion Date, the
                  Holder may, by notice to the Company, require the Company to
                  issue shares of Common Stock pursuant to Section 4(c), except
                  that for such purpose the Conversion Price applicable thereto
                  shall be the lesser of the Conversion Price on the Conversion
                  Date and the Conversion Price on the date of such Holder
                  demand. Any such shares will be subject to the provision of
                  this Section.

                           (iii) In addition to any other rights available to
                  the Holder, if the Company fails to deliver to the Holder such
                  certificate or certificates pursuant to Section 4(b)(i), by
                  the third (3rd) Trading Day after the Conversion Date, and if
                  after such third (3rd) Trading Day the Holder purchases (in an
                  open market transaction or otherwise) Common Stock to deliver
                  in satisfaction of a sale by such Holder of the Underlying
                  Shares which the Holder anticipated receiving upon such
                  conversion (a "BUY-IN"), then the Company shall (A) pay in
                  cash to the Holder (in addition to any remedies available to
                  or elected by the Holder) the amount by which (x) the Holder's

                                       -5-
<PAGE>

                  total purchase price (including brokerage commissions, if any)
                  for the Common Stock so purchased exceeds (y) the product of
                  (1) the aggregate number of shares of Common Stock that such
                  Holder anticipated receiving from the conversion at issue
                  multiplied by (2) the market price of the Common Stock at the
                  time of the sale giving rise to such purchase obligation and
                  (B) at the option of the Holder, either reissue Debentures in
                  principal amount equal the principal amount of the attempted
                  conversion or deliver to the Holder the number of shares of
                  Common Stock that would have been issued had the Company
                  timely complied with its delivery requirements under Section
                  4(b)(i). For example, if the Holder purchases Common Stock
                  having a total purchase price of $11,000 to cover a Buy-In
                  with respect to an attempted conversion of Debentures with
                  respect to which the market price of the Underlying Shares on
                  the date of conversion was a total of $10,000 under clause (A)
                  of the immediately preceding sentence, the Company shall be
                  required to pay the Holder $1,000. The Holder shall provide
                  the Company written notice indicating the amounts payable to
                  the Holder in respect of the Buy-In. Notwithstanding anything
                  contained herein to the contrary, if a Holder requires the
                  Company to make payment in respect of a Buy-In for the failure
                  to timely deliver certificates hereunder and the Company
                  timely pays in full such payment, the Company shall not be
                  required to pay such Holder liquidated damages under Section
                  4(b)(ii) in respect of the certificates resulting in such
                  Buy-In.

                  (c)      (i) The conversion price (the "CONVERSION PRICE") in
                  effect on any Conversion Date shall be the closing sale price
                  of the Common Stock on the Conversion Date which must be a
                  Trading Day. Notwithstanding the foregoing, the Conversion
                  Price shall not be less than the Floor (as defined in Section
                  7) for so long as the Floor remains in effect in accordance
                  with Section 6; PROVIDED, that the Floor shall be subject to
                  reduction due to operation of this Section 4(c).

                           (ii) In case of any reclassification of the Common
                  Stock or any compulsory share exchange pursuant to which the
                  Common Stock is converted into other securities, cash or
                  property, the Holders shall have the right thereafter to, at
                  their option, (A) convert the then outstanding principal
                  amount only into the shares of stock and other securities,
                  cash and property receivable upon or deemed to be held by
                  holders of the Common Stock following such reclassification or
                  share exchange, and the Holders of the Debentures shall be
                  entitled upon such event to receive such amount of securities,
                  cash or property as the shares of the Common Stock of the
                  Company into which the then outstanding principal amount could
                  have been converted immediately prior to such reclassification
                  or share exchange would have been entitled or (B) require the
                  Company to prepay the aggregate of its outstanding principal
                  amount of Debentures. The entire prepayment price shall be
                  paid in cash. This provision shall similarly apply to
                  successive reclassifications or share exchanges.

                           (iii) All calculations under this Section 4 shall be
                  made to the nearest cent or the nearest 1/100th of a share, as
                  the case may be.

                           (iv) If (A) the Company shall declare a special
                  nonrecurring cash dividend on or a redemption of the Common
                  Stock; (B) the Company shall authorize the granting to all
                  holders of the Common Stock rights or warrants to subscribe
                  for or purchase any shares of capital stock of any class or of
                  any rights; (C) the approval of any stockholders of the
                  Company shall be required in connection with any
                  reclassification of the Common Stock, any consolidation or
                  merger to which the Company is a party, any sale or transfer
                  of all or substantially all of the assets of the Company, of
                  any compulsory share exchange whereby the Common Stock is
                  converted into other securities, cash or property; (D) the
                  Company shall authorize the voluntary or involuntary
                  dissolution, liquidation or winding up of the affairs of the
                  Company; then, in each case, the Company shall give notice to
                  the Holders as provided in subsection (g) below at least 20
                  calendar days prior to the applicable record or effective date
                  hereinafter specified, a notice stating (x) the date on which
                  a record is to be taken for the purpose of such dividend,
                  distribution, redemption, rights or warrants, or if a record
                  is not to be taken, the date as of which the holders of the
                  Common Stock of record to be entitled to such dividend,
                  distributions, redemption, rights or warrants are to be
                  determined or (y) the date on which such reclassification,

                  of this Debenture and shall be entitled to all of the rights
                  and privileges of a Holder of Debentures set forth herein, and

                  have been converted immediately prior to such tender or

                  Common Stock would receive in such transaction and the
                  Conversion Price in effect immediately prior to the
                  effectiveness or closing date for such transaction. The terms
                  of any such merger, sale, consolidation, tender or exchange
                  shall include such terms so as to continue to give the Holders
                  of Debentures the right to receive the securities, cash and
                  property set forth in this Section upon any conversion or
                  redemption following such event. This provision shall

         payment of interest hereunder. The Company covenants that all shares of
         Common Stock that shall be so issuable shall, upon issue, be duly and

         value of a share of Common Stock at such time. If the Company elects

         the Holders thereof for any documentary stamp or similar taxes that may
         be payable in respect of the issue or delivery of such certificate,
         provided that the Company shall not be required to pay any tax that may
         be payable in respect of any transfer involved in the issuance and
         delivery of any such certificate upon conversion in a name other than
         that of the Holder of such Debentures so converted and the Company
         shall not be required to issue or deliver such certificates unless or

this Debenture. The failure of the Company or the Holder to insist upon strict
adherence to any term of this Debenture on one or more occasions shall not be

provision is inapplicable to any person or circumstance, it shall nevertheless
remain applicable to all other persons and circumstances.

due on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day.

         Re:  REGISTRATION STATEMENT ON FORM S-3
         ---  ----------------------------------

Ladies and Gentlemen:

         At your request, we have examined the form of Registration Statement on
Form S-3 (the "Registration Statement") to be filed by Premier Laser Systems,
Inc. (the "Company") with the Securities and Exchange Commission pursuant to the
Securities Act of 1933, as amended, for the purpose of registering the sale of
certain shares of Class A Common Stock of the Company (the "Common Stock") by
the securityholders set forth therein. We are familiar with the proceedings
taken and proposed to be taken in connection with the issuance and sale of the
securities in the manner set forth in the Registration Statement. Subject to
completion of the proceedings contemplated in connection with the foregoing
matters, we are of the opinion that all of the Common Stock to be sold pursuant
to the Registration Statement has been duly authorized and, when issued and sold
in the manner set forth in the Registration Statement will, upon such issuance
and sale, be validly and legally issued, fully paid and nonassessable.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement or any amendment thereto.

                                                     Respectfully submitted,


                                                     /s/ RUTAN & TUCKER, LLP









                                                                    Exhibit 10.1

                              SETTLEMENT AGREEMENT
                              --------------------


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

                                   WITNESSETH:

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

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

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

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


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

         2. ISSUANCE OF CONVERTIBLE DEBENTURES.

                  2.1.     AMOUNT OF DEBENTURES ISSUED. Simultaneously with the
                           execution of this Agreement, PLSI shall issue to BSLT
                           a series of six debentures (the "Debentures") as
                           follows: five debentures in the amount of One Hundred
                           Thousand Dollars and 00/100 U.S. Dollars (US$
                           100,000.00) and one debenture in the amount of
                           Ninety-One Thousand Nine Hundred Sixteen and 06/100
                           U.S. Dollars (US$ 91,916.00) each in the form set
                           forth in Exhibit A.


<PAGE>

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

                  2.2.     REGISTRATION OF THE DEBENTURES. Within five (5)
                           Business Days of the execution of this Agreement and
                           issuance of the Debentures (or in the case of
                           issuance of New Debentures as provided in
                           subparagraph 2.3 below, within five (5) days of the
                           issuance of the New Debentures), PLSI agrees to file
                           the necessary documentation with the SEC to register
                           the Underlying Shares under the Act, and to
                           thereafter prosecute such application in good faith
                           and with its best efforts. A copy of all filings by
                           PLSI with respect to the Underlying Shares shall be
                           provided to BSLT by the notice procedures set forth
                           in subparagraph 10.1 below within two (2) Business
                           Days on which the filing was made with the SEC. In
                           addition, Notice of the effectiveness of such
                           registration shall be given by PLSI to BSLT within
                           two (2) Business Days of the effectiveness of such
                           Registration.

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

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

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

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

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

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

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

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

                           Goods that BSLT has previously delivered to PLSI, or

                  5.2.     RELEASE BY BSLT. Upon issuance of the Debentures to

                                    Shares for an indefinite period of time, is
                                    able to bear the economic risk of an
                                    investment in the Shares and is able to
                                    withstand a complete loss of its investment

<PAGE>

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

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

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

                           8.4.8.   BSLT understands that the Shares may be sold
                                    only (i) upon registration of the Shares
                                    pursuant to the Securities Act of 1933 (the

                  10.2.    ASSIGNMENT. This Agreement may not be assigned in

                           written approval by the other party; provided that
                           the Agreement may be assigned, in the case of
                           corporate reorganization, to an entity controlled by
                           the assigning party or under common control with the
                           assigning party.

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

                  10.4.    GOVERNING LAW. The internal law, without regard to
                           conflicts of laws principles, of the State of

                           construction, validity and interpretation of this
                           Agreement and the performance of the obligations
                           imposed by this Agreement.

                  10.5.    VENUE AND JURISDICTION. All actions brought against
                           PLSI under this Agreement, including any of the

                           brought in the state or federal courts located in the
                           State of Montana. PLSI hereby irrevocably waives
                           personal service of process and consents to process
                           being served in any such suit, action or proceeding
                           by receiving a copy thereof sent to PLSI at the

                           10.1 above and agrees that such service shall
                           constitute good and sufficient service of process and
                           notice thereof. Nothing contained herein shall be
                           deemed to limit in any way any right by BSLT to serve
                           process in any manner permitted by law.

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

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

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

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

                  10.10.   RULES OF CONSTRUCTION. All parties have entered into
                           this Agreement upon the advice of counsel and with

                           Accordingly, the parties agree that the principle
                           that would construe a contract strictly against the
                           party who drafted such contract shall have no
                           application to this Agreement.

         IN WITNESS WHEREOF, the undersigned officers of the party, having been
duly authorized to bind their respective parties, have executed this Agreement

                               EXCHANGE AGREEMENT
                               ------------------


         This Exchange Agreement (the "AGREEMENT") entered into as of the last
date written below by and between ___________________ ("CREDITOR"), a California
limited liability partnership with its principal place of business at __________
________________________________________, and Premier Laser Systems,
Inc. ("PLSI"), a California corporation, having its principal place of business
at 3 Morgan, Irvine, California.

                                   WITNESSETH:

         WHEREAS, PLSI is indebted to Creditor in an amount in excess of
____________ as a result of products or services provided by Creditor to PLSI;

         WHEREAS, PLSI and Creditor wish to agree upon a payment mechanism that
would permit PLSI to pay a portion of such debt;

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

1.       LIQUIDATION OF DEBT.

         The parties hereby agree that, as of the date of this Agreement, the
total amount due and owing by PLSI to Creditor is at least equal to the sum of
_________________________ (___________) (such sum being hereafter referred to as
the "LIQUIDATED DEBT"). PLSI agrees to pay the Liquidated Debt to Creditor
pursuant to the terms and conditions set forth in this Agreement. As used
herein, the term "Liquidated Debt" does NOT refer to any amount of debt in
excess of __________________________ (___________).

2.       ISSUANCE OF CONVERTIBLE DEBENTURES.

         2.1      AMOUNT OF DEBENTURES ISSUED. Simultaneously with the execution
                  of this Agreement, PLSI shall issue to Creditor a series of
                  ____ (_) convertible debentures (the "DEBENTURES") in the
                  amount of __________________ Dollars and 00/100 U.S. Dollars
                  (US$______) each in the form set forth in EXHIBIT A. The
                  Debentures shall be convertible into the Common Stock of PLSI
                  (the "UNDERLYING SHARES" or "SHARES") pursuant to the terms
                  and conditions set forth in the Debentures. Following the
                  issuance of the Debentures, the Debentures shall thereafter
                  represent the Liquidated Debt, and thereafter there shall be
                  no independent debt from PLSI to Creditor with respect to the
                  Liquidated Debt. The parties acknowledge, however, that the
                  total indebtedness of PLSI to Creditor may exceed the
                  Liquidated Debt, and the exchange of the Debentures for the
                  Liquidated Debt shall not extinguish or otherwise affect any
                  additional indebtedness that PLSI may have to Creditor.

         2.2      REGISTRATION OF THE UNDERLYING SHARES. Within ten (10)
                  Business Days of the execution of this Agreement and issuance
                  of the Debentures, PLSI agrees to file a Registration
                  Statement with the Commission to register the resale of the
                  Underlying Shares under the Act, and to thereafter prosecute
                  such application in good faith and with its best efforts. PLSI
                  will keep such Registration Statement effective until the
                  earlier of that date 18 months from its effective date or the
                  date that the selling securityholders named therein have
                  converted all of the Debentures held by them AND sold all of
                  the Common Stock received by them upon conversion. During this
                  period, PLSI shall amend the Registration Statement and the
                  prospectus included therein, and any documents incorporated by
                  reference therein, as necessary to ensure that it does include
                  any misstatement of a material fact or omit to state a fact
                  necessary to make the other statements contained therein not
                  misleading. A copy of all filings by PLSI with respect to the
                  Underlying Shares shall be provided to Creditor by the notice
                  procedures set forth in subparagraph 8.1 below within five (5)
                  Business Days on which the filing was made with the
                  Commission. In addition, Notice of the effectiveness of such
                  registration shall be given by PLSI to Creditor within five
                  (5) Business Days of the effectiveness of such Registration.

         2.3      INDEMNIFICATION. PLSI agrees to indemnify and hold harmless
                  Creditor and its officers, directors, agents, partners and any
                  person who may be deemed to control Creditor under the Act or
                  the Securities Exchange Act of 1934, to the fullest extent
                  permitted by law, from and against any and all losses, claims,
                  damages, liabilities, costs and expenses (including without
                  limitation attorneys' fees), as incurred, arising out or
                  relating to any untrue or alleged untrue statement of a
                  material fact contained in the Registration Statement or the
                  prospectus contained therein, or arising out of or relating to
                  any omission or alleged omission of a material fact required
                  to be stated therein or necessary to make the statements
                  therein not misleading, except to the extent, but only to the
                  extent, that such untrue statements or omissions are based
                  solely upon information regarding the Creditor furnished in
                  writing by the Creditor to PLSI expressly for use therein.

3.       LIMITATION ON SALE OF SHARES.

         Commencing on the effective date of the registration of the Underlying
Shares, Creditor agrees that it will not sell on any public exchange (including
without limitation the Nasdaq National Market) an amount of the Underlying
Shares for an aggregate sales price in excess of ______________ U.S. Dollars
(US$________) in any calendar month.

4.       MANDATORY CONVERSION.

         PLSI shall have the option, but not the obligation, to require
Creditor, upon five (5) business days notice, to convert any or all of the
Debentures, provided that:

         4.1      The Underlying Shares are covered by an effective registration
                  statement freely permitting Creditor to sell the Underlying
                  Shares on a public market;

         4.2      The Common Stock of PLSI is listed on the NASDAQ National
                  Market or Nasdaq Small Cap Market;

                                        2
<PAGE>

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

         4.4      The conversion of the Debentures in accordance with such
                  notice from PLSI will not result in Creditor having converted
                  more that $______ of the Debentures in any calendar month.

5.       REPRESENTATIONS AND WARRANTIES OF PLSI.

         PLSI hereby represents and warrants to Creditor as follows:

                  good standing, is qualified to do business in the State of

                  shareholders, officers and directors required by its Articles,

                  Agreement and to issue the Debentures as provided herein. The
                  Debentures, when issued in accordance herewith, shall be the
                  valid and binding obligations of PLSI, enforceable in
                  accordance with their terms. The issuance of the Underlying
                  Shares upon the conversion of the Debentures in accordance
                  with their terms has been approved by all necessary corporate
                  action on the part of PLSI, and upon such conversion the
                  Underlying Shares shall be duly and validly authorized, fully

         6.3      KNOWLEDGE OF, AND CAPACITY TO ASSUME, ECONOMIC RISK. Creditor
                  acknowledges and represents that:

                  6.3.1    Creditor is an "accredited investor" as defined in
                           Exhibit B hereto;

                  6.3.2    Creditor has received and reviewed PLSI's Annual
                           Report on Form 10-K/A for the fiscal year ended March

<PAGE>

                  6.3.4    Creditor has such knowledge and experience in
                           business and financial matters that make it capable

                  6.3.5    Creditor understands that an investment in the Shares
                           is highly speculative and involves a high degree of
                           risk but believes that an investment in the Shares is
                           suitable based upon its investment objectives and
                           financial needs, and that it has adequate means to
                           undertake the risk and to provide for its current
                           financial needs and has no need for liquidity of
                           investment with respect to the Shares; Creditor has
                           reviewed and understands the Risk Factors attached
                           hereto as EXHIBIT A;

                  6.3.6    Creditor has had the opportunity to ask questions of,
                           and receive answers from, representatives of PLSI,
                           for the purpose of obtaining any additional
                           information to the extent reasonably available that
                           is necessary to verify the information provided;

                  6.3.7    Creditor understands that the Shares may be resold by
                           it only (i) upon registration of the Shares pursuant
                           to the Act or (ii) in a transaction that is exempt
                           from registration under the Act. Creditor understands
                           that until the resale of the Underlying Shares is
                           registered under the Act, the certificates
                           representing the Underlying Shares will bear a legend
                           restricting the sale or other disposition thereof.

                  6.3.8    Creditor is acquiring the Debentures and the
                           Underlying Shares for purposes of investment, and
                           without a view to the distribution or resale thereof
                           except where such distribution or resale is
                           registered under the Act or otherwise permitted by
                           applicable securities laws.

                  6.3.9    Creditor is a resident of or domiciled in the state
                           set forth under its name in Section 8.1 hereof.

                                    EXHIBIT C

                                  RISK FACTORS


         RISKS RELATED TO OUR BUSINESS

IF WE ARE UNABLE TO SECURE ADDITIONAL FINANCING IN THE FUTURE, WE WILL HAVE TO
DELAY OR HALT OUR PRODUCT DEVELOPMENT PROGRAMS.

         In the future, we will require substantial additional funds for
research and development programs, preclinical and clinical testing, development
of our sales and distribution force, operating expenses, regulatory processes
and manufacturing and marketing programs. Our capital requirements may vary, and
will depend on both internal and external factors. Internal factors affecting
our capital requirements include:

         o        the progress of research and development programs

         o        results of preclinical and clinical testing

         o        the cost of filing, prosecuting, defending and enforcing any
                  patent claims and other intellectual property rights

         o        developments and changes in our existing research

         o        licensing and other relationships

         o        the terms of any new collaborative, licensing and other
                  arrangements that we may establish.

         o        the amount of legal, accounting and administrative costs
                  incurred in connection with pending litigation

         External factors affecting our capital requirements include:

         o        competing technological and market developments

         o        the time and cost involved in obtaining regulatory approvals

         OUR AVAILABLE SHORT-TERM ASSETS AND INVESTMENT INCOME WILL NOT BE
SUFFICIENT TO MEET OUR OPERATING EXPENSES AND CAPITAL EXPENDITURES THROUGH THE
CURRENT FISCAL YEAR. WE ARE CURRENTLY IN THE PROCESS OF SEEKING ADDITIONAL
FINANCING. WE DO NOT KNOW IF ADDITIONAL FINANCING WILL BE AVAILABLE WHEN NEEDED,
OR IF IT IS AVAILABLE, IF IT WILL BE AVAILABLE ON ACCEPTABLE TERMS. INSUFFICIENT
FUNDS MAY PREVENT US FROM IMPLEMENTING OUR BUSINESS STRATEGY OR MAY REQUIRE US
TO DELAY, SCALE BACK OR ELIMINATE RESEARCH AND PRODUCT DEVELOPMENT PROGRAMS OR
TO LICENSE TO THIRD PARTIES RIGHTS TO COMMERCIALIZE PRODUCTS OR TECHNOLOGIES
THAT WE WOULD OTHERWISE SEEK TO DEVELOP INTERNALLY.

WE HAVE INCURRED NET LOSSES IN THE PAST AND EXPECT TO INCUR FUTURE LOSSES WHICH
MAY NEGATIVELY IMPACT OUR ABILITY TO SUSTAIN OUR OPERATIONS.

                                        9
<PAGE>

         We incurred net losses of approximately $76,343,000 from April 1, 1995
through March 31, 1999, and approximately $30,841,000 for the year ended March
31, 1999. As of March 31, 1999, we had an accumulated deficit of approximately
$89,207,000. We have incurred additional losses since that date, and expect to
continue to incur net losses until product sales generate sufficient revenues to
fund our continuing operations. We may fail to achieve significant revenues from
sales or achieve or sustain profitability. Our ability to achieve profitability
in the future will depend in part on our ability to continue to successfully
develop clinical applications, obtain regulatory approvals for our products and
sell these products on a wide scale. These risks apply to both our laser
products and our ophthalmic diagnostic products.

THE HIGH COST OF DENTAL LASERS, SAFETY AND EFFICACY CONCERNS OF DENTISTS AND
PATIENTS AND THE SUBSTANTIAL MARKET ACCEPTANCE OF DENTAL DRILLS MAY PREVENT US
FROM ACHIEVING THE BROAD MARKET ACCEPTANCE WHICH IS NECESSARY FOR OUR SUCCESS.

         Our products may not be accepted by the medical or dental community or
by patients. We do not know if these products can be successfully commercialized
on a broad basis. The acceptance of dental lasers may be adversely affected by
their high cost, concerns by patients and dentists relating to their safety and
efficacy, and the substantial market acceptance and penetration of alternative
dental tools such as the dental drill. Our future sales and profitability depend
in part on our ability to demonstrate to dentists, ophthalmologists,
optometrists and other physicians the potential cost and performance advantages
of our laser systems, diagnostic products and other products over traditional
methods of treatment and over competitive products. Current economic pressure
may make doctors and dentists reluctant to purchase substantial capital
equipment or invest in new technology. We currently have a limited sales force
and will need to hire additional sales and marketing personnel to increase the
general acceptance of our products. Of all the factors impacting our
profitability, the failure of our products to achieve broad market acceptance
would have the greatest negative impact on our business, financial condition and
results of operations and our profitability.

WE ARE INVOLVED IN PENDING LITIGATION AND A REGULATORY INVESTIGATION AND MAY BE
ADVERSELY AFFECTED BY AN ADVERSE OUTCOME IN THE LAWSUIT OR BY THE COSTS OF
DEFENDING THIS LAWSUIT.

         We have been sued in a number of related securities class action
matters, generally relating to allegations of misrepresentations during the
period from May 7, 1997 to April 15, 1998. In addition, the Securities and
Exchange Commission has commenced an investigation of our practices and
procedures relating to revenue recognition issues and related matters. The costs
of our continuing defense of the litigation matters and responses to the
regulatory investigations, including accounting and legal fees as well as
management time and effort, will be substantial, and we expect these costs to
materially and adversely affect our results of operations until these matters
are resolved. We do not know when these matters will be resolved. We have
reached an agreement in principle to settle the class action litigation and
recorded an expense in the quarter ended December 31, 1998, relating to this
settlement. We have recorded substantial additional expense since that date to
cover continuing legal fees incurred in connection with this settlement.
However, this settlement is subject to several conditions, and it is possible
that it may not be completed, in which case the litigation would continue. An
adverse judgment entered in this litigation could materially and adversely
affect our business and results of operations.

         In addition, the Securities and Exchange Commission is empowered to
assess substantial penalties against us in connection with its findings in the
pending investigation. The imposition of any of these penalties could materially
and adversely affect our business, financial condition and results of
operations.

                                       10
<PAGE>

IF WE ARE UNABLE TO SUCCESSFULLY INTEGRATE THE OPHTHALMIC IMAGING SYSTEMS
("OIS") BUSINESS WITH OUR OTHER OPERATIONS, WE MAY INCUR SUBSTANTIAL AND
UNANTICIPATED EXPENSES AND OPERATING INEFFICIENCIES.

         We acquired a majority of the outstanding common stock of OIS in 1998.
In March 1999, we agreed to manufacture OIS's products on an outsourcing basis.
In addition, we have agreed with OIS to acquire the remaining outstanding stock
of OIS, subject to satisfaction of certain conditions. We are not sure if the
synergies of the two entities will allow us to reduce expenses in such a way as
to make OIS profitable. In addition, members of our management will have to
continue to expend time and effort on new activities relating to the OIS
operations, which will detract from their time available to attend to our other
activities. We cannot assure you that the expenses or dislocations that we may
suffer as a result of the coordination of these businesses will not be material.

BECAUSE SOME OF THE COMPONENTS WE USE ARE NOT WIDELY AVAILABLE, THERE IS A RISK
THAT WE MAY NOT ALWAYS BE ABLE TO OBTAIN THESE COMPONENTS, WHICH COULD PREVENT
US FROM FILLING ORDERS ON TIME AND REDUCE OUR SALES.

         We purchase some of the raw materials, components and subassemblies
included in our products from a limited group of qualified suppliers and do not
maintain long-term supply contracts with any of our key suppliers. Some of the
components used by OIS are manufactured by a sole vendor, including Foresight
Imaging for its prism card and Kodak for its 12 bit camera. In addition, our
Arago laser product is manufactured for us by one supplier, LaserMed, Inc.
Further, our components are subject to rapid innovation and obsolescence. The
discontinuance of the manufacturing of these components may require us to
redesign some of the hardware and software used in our products to accommodate a
replacement component. While we believe that suppliers could be found for all of
our components and products, we cannot assure you that any supplier could be
replaced in a timely manner. Any interruption in the supply of key components
could materially harm our ability to manufacture our products and our business,
financial condition and results of operations.

IN ORDER TO CONTINUE TO SELL OUR PRODUCTS IN FOREIGN MARKETS, WE MUST DEVELOP
AND MAINTAIN FOREIGN SALES DISTRIBUTION CHANNELS AND MANAGE POLITICAL AND
ECONOMIC INSTABILITY IN FOREIGN MARKETS AND DEAL WITH GOVERNMENTAL QUOTAS AND
OTHER REGULATIONS.

         A substantial portion of our sales are made in foreign markets. The
primary risks to which we are exposed due to our foreign sales are the
difficulty and expense of maintaining foreign sales distribution channels,
political and economic instability in foreign markets and governmental quotas
and other regulations.

         The regulation of medical devices worldwide also continues to develop,
and it is possible that new laws or regulations could be enacted which would
have an adverse effect on our business. In addition, we may experience
additional difficulties in providing prompt and cost effective service of our
medical lasers in foreign countries. We do not carry insurance against these
risks. The occurrence of any one or more of these events may individually or in
the aggregate have a material adverse effect upon our business, financial
condition and results of operations.

IF WE CANNOT ADAPT TO TECHNOLOGICAL ADVANCES, OUR PRODUCTS MAY BECOME
TECHNOLOGICALLY OBSOLETE AND OUR PRODUCT SALES COULD SIGNIFICANTLY DECLINE.

                                       11
<PAGE>

         The markets in which our medical products compete are subject to rapid
technological change as well as the potential development of alternative
surgical techniques or new pharmaceutical products. These changes could render
our products uncompetitive or obsolete. We will be required to invest in
research and development to attempt to maintain and enhance our existing
products and develop new products. We do not know if our research and
development efforts will result in the introduction of new products or product
improvements.

IF WE ARE UNABLE TO PROTECT OUR PATENTS AND PROPRIETARY TECHNOLOGY WE MAY NOT BE
ABLE TO COMPETE EFFECTIVELY.

         Our success will depend in part on our ability to obtain patent
protection for products and processes, to preserve our trade secrets and to
operate without infringing the proprietary rights of third parties. While we
hold a number of U.S. and foreign patents and have other patent applications
pending in the United States and foreign countries, we cannot assure you that
any additional patents will be issued, that the scope of any patent protection
will exclude competitors or that any of our patents will be held valid if
subsequently challenged. Further, other companies may independently develop
similar products, duplicate our products or design products that circumvent our
patents. We are aware of certain patents which, along with other patents that
may exist or be granted in the future, could restrict our right to market some
of our technologies without a license, including, among others, patents relating
to our lens emulsification product and ophthalmic probes for the Er:YAG laser.

         We also rely upon unpatented trade secrets, and we cannot assure you
that others will not independently develop or otherwise acquire substantially
equivalent trade secrets. In addition, at each balance sheet date, we are
required to review the value of our intangible assets based on various factors,
such as changes in technology. Any adjustment downward in the value of our
intangible assets may result in a write-off of the intangible asset and a
substantial charge to earnings, which would adversely affect our operating
results in the future.

IN OUR BUSINESS, WE COULD BECOME INVOLVED IN PATENT AND INTELLECTUAL PROPERTY
LITIGATION, IN WHICH AN ADVERSE DETERMINATION COULD SUBJECT US TO SIGNIFICANT
LIABILITIES AND RESTRICT OUR MANUFACTURING RIGHTS.

         In the past, we have received allegations that some of our laser and
diagnostic products infringe on other patents. There has been significant patent
litigation in the medical device industry. Adverse determinations in litigation
or other patent proceedings to which we may become a party could subject us to
significant legal judgments or other liabilities to third parties and could
require us to seek licenses from third parties that may or may not be
economically viable. We cannot assure you that any licenses required under these
or any other patents or proprietary rights would be available on terms
acceptable to us. If we do not obtain these licenses, we could encounter delays
in product introductions while we attempt to design around these patents, or we
could find that the development, manufacture or sale of products requiring such
licenses could be enjoined.

OUR BUSINESS IS SUBJECT TO GOVERNMENTAL REGULATION WHICH IMPOSES SIGNIFICANT
COSTS ON US AND IF NOT COMPLIED WITH COULD LEAD TO THE ASSESSMENT OF PENALTIES.

         Our products are regulated as medical devices by the United States Food
& Drug Administration. As such, these devices require either Section 510(k)
premarket clearance or approval of a premarket approval application by the FDA
prior to commercialization. Satisfaction of regulatory requirements is expensive
and may take several years to complete. We cannot assure you that further
clinical trials of our medical products or of any future products will be
successfully completed or, if they are completed, that any requisite FDA or
foreign governmental approvals will be obtained.

                                       12
<PAGE>

         FDA or other governmental approvals of products we may develop in the
future may require substantial filing fees which could limit the number of
applications we seek and may entail limitations on the indicated uses for which
our products may be marketed. In addition, approved or cleared products may be
subject to additional testing and surveillance programs required by the FDA and
other regulatory agencies, and product approvals and clearances could be
withdrawn for failure to comply with regulatory standards or by the occurrence
of unforeseen problems following initial marketing. Also, we have made
modifications to some of our existing products which we do not believe require
the submission of a new 510(k) notification to the FDA. However, we cannot
assure you that the FDA would agree with our determination. If the FDA did not
agree with our determination, they could require us to cease marketing one or
more of the modified devices until the devices have been cleared.

         We are also required to adhere to a wide variety of other regulations
governing the operation of our business. Noncompliance with state, local,
federal or foreign requirements can result in serious penalties that could harm
our business.

THE INTENSE COMPETITION WE FACE COULD RESULT IN REDUCED SALES AND DOWNWARD
PRESSURE ON THE PRICES OF OUR PRODUCTS.

         We are, and will continue to be, subject to intense competition in our
targeted markets, principally from businesses providing other traditional
surgical and nonsurgical treatments, including existing and developing
technologies, and competitive products. Many of our competitors have
substantially greater financial, marketing and manufacturing resources and
experience than us. In addition, we expect that other companies will enter the
laser market, particularly as medical lasers gain increasing market acceptance.
Significant competitive factors which will affect future sales in the
marketplace include regulatory approvals, performance, pricing and general
market acceptance.

         The ophthalmic diagnostic market is also highly competitive. There are
many companies engaged in this market, some with significantly greater resources
than ours. Our competitors may be able to develop technologies, procedures or
products that are more effective or economical than ours, or that would render
our products obsolete or noncompetitive.

         To continue to remain competitive, we must develop new software and
hardware meeting the needs of ophthalmologists and optometrists. Our future
revenues will depend, in part, on our ability to develop and commercialize these
new products as well as on the success of development and commercialization
efforts of our competitors.

A SUCCESSFUL PRODUCT LIABILITY CLAIM ASSERTED AGAINST US DUE TO A DEFECT IN ONE
OF OUR PRODUCTS IN EXCESS OF OUR INSURANCE COVERAGE WOULD HARM OUR BUSINESS.

         The sale of our medical products involves the inherent risk of product
liability claims against us. We currently maintain product liability insurance
coverage in the amount of $5 million per occurrence and $5 million in the
aggregate, but this insurance is expensive, subject to various coverage
exclusions and may not be obtainable in the future on terms acceptable to us. We
do not know whether claims against us arising with respect to our products will
be successfully defended or that our insurance will be sufficient to cover
liabilities arising from these claims. A successful claim against us in excess
of our insurance coverage could materially harm our business.

                                       13
<PAGE>

THERE IS UNCERTAINTY RELATING TO THIRD PARTY REIMBURSEMENT WHICH IS CRITICAL TO
MARKET ACCEPTANCE OF OUR PRODUCTS.

         Our laser systems and other products are generally purchased by
physicians, dentists and surgical centers which then bill various third party
payors, such as government programs and private insurance plans, for the
procedures conducted using these products. Third-party payors carefully review
and are increasingly challenging the prices charged for medical products and
services, and scrutinizing whether to cover new products and evaluating the
level of reimbursement for covered products. While we believe that the laser
procedures using our products have generally been reimbursed, payors may deny
coverage and reimbursement for our products if they determine that the device
was not reasonable and necessary for the purpose for which it was used, was
investigational or not cost-effective. As a result, we cannot assure you that
reimbursement from third party payors for these procedures will be available or
if available, that reimbursement will not be limited. If third party
reimbursement of these procedures is not available, it will be more difficult
for us to sell our products on a profitable basis. Moreover, we are unable to
predict what legislation or regulation, if any, relating to the health care
industry or third-party coverage and reimbursement may be enacted in the future,
or what effect such legislation or regulation may have on us.

THE COVERAGE AND SPENDING LIMITATIONS CONTAINED IN HEALTH CARE REFORM PROPOSALS
WOULD, IF ADOPTED, REDUCE DEMAND FOR OUR PRODUCTS.

         Several states and the United States government are investigating a
variety of alternatives to reform the health care delivery system and further
reduce and control health care spending. These reform efforts include proposals
to limit spending on health care items and services, limit coverage for new
technology and limit or control the price health care providers and drug and
device manufacturers may charge for their services and products. If adopted and
implemented, such reforms could have a material adverse effect on our business,
financial condition and results of operations.

IF WE EXPERIENCE PROBLEMS WITH YEAR 2000 COMPLIANCE OUR OPERATIONS MAY BE
DISRUPTED.

         Many existing computer programs use only two digits to identify the
year in the date field. These programs were designed and developed without
considering the impact of the upcoming change in the century. As a result, any
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the Year 2000. This could result in system
failure or miscalculations, causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices or
engage in similar normal business activities.

         We are heavily dependent upon the proper functioning of our own
computer and data- dependent systems. This includes, but it not limited to, our
support/administrative and operational/production systems. Any failure or
malfunctioning on the part of these or other systems could harm our business in
ways that we currently do not know and cannot discern, quantify or otherwise
anticipate. In addition, if our key vendors experience Year 2000 compliance
issues, then our business could be harmed. Due to the interrelated nature of
international commerce, if there is a failure in Year 2000 compliance by us or
one of our direct or indirect business partners, we could suffer major
disruptions in our ability to call on customers, obtain orders from customers,
obtain parts from suppliers, manufacture products for sale, ship products to our
customers, or receive payment for our sales.

                                       14
<PAGE>

         We have not developed a formal assessment of all potential impacts of
the Year 2000. We design, manufacture and sell medical products which contain
computer chips and we utilize software developed by other companies. While our
engineers are developing new software which they expect to complete by December
31, 1999, there can be no assurance that their efforts will be successful. We
rely on external business partners. As such, there can be no assurance that our
business will not be negatively affected by Year 2000 problems experienced by
these business partners.

RISKS RELATED TO THIS OFFERING

CHANGES IN REVENUE AND OPERATING RESULTS MAY CAUSE THE MARKET PRICE OF OUR STOCK
TO FLUCTUATE, WHICH MAY ADVERSELY AFFECT OUR ABILITY TO RAISE ADDITIONAL
CAPITAL.

         Due to the relatively high sales price of our products and low sales
unit volume, minor timing differences in receipt of customer orders have
produced and could continue to produce significant fluctuations in quarterly
results. In addition, if anticipated sales and shipments in any quarter do not
occur when expected, expenditures and inventory levels could be
disproportionately high, and our operating results for that quarter, and
potentially for future quarters, would be adversely affected. Quarterly results
may also fluctuate based on a variety of other factors. The important factors
which may cause our quarterly results to fluctuate are seasonality and
production delays. During the past four fiscal quarters, our net loss has
fluctuated from a low of $2.1 million to a high of $12.9 million. Such
fluctuations may cause our stock price to decline and adversely affect our
ability to raise additional capital.

THE VOLATILITY OF OUR STOCK PRICE MAKES THESE SECURITIES RISKY FOR THOSE SEEKING
A STABLE INVESTMENT.

         The market price of our common stock is very volatile, and our common
stock therefore may not be a suitable investment for those who seek stable
investment prices over the short or long term. Our common stock was first
publicly traded in December 1994 and has had last reported closing sale prices
ranging from a low of $1.38 per share in August 1999 to a high of $14.00 per
share in May 1997. The market price of our common stock could continue to
fluctuate substantially due to a variety of risk factors, including those
described elsewhere in this prospectus. The market price for our common stock
may also be affected by our ability to meet analysts' expectations. Any failure
to meet these expectations, even slightly, could have an adverse effect on the
market price of our common stock. In addition, the market prices of securities
issued by many companies may change for reasons unrelated to the operating
performance of these companies. In the past, following periods of volatility in
the market price of a company's securities, securities class action litigation
has often been instituted against the company. If similar litigation were
instituted against us, it could result in substantial costs and a diversion of
our management's attention and resources, which could have an adverse effect on
our business, results of operations and financial condition.

A SIGNIFICANT NUMBER OF SHARES ARE ELIGIBLE FOR SALE, AND IF SOLD, THESE SHARES
MAY CREATE EXCESS SUPPLY IN THE MARKET CAUSING OUR STOCK PRICE TO DECLINE.

         Sales of a substantial number of our shares of common stock in the
public market could adversely affect the market price for our common stock. At
this time, approximately 7.6 million shares of our common stock are issuable
upon the full exercise of our outstanding Class B Warrants, and over 6.4 million
shares of our common stock are issuable upon exercise of other outstanding
warrants and options and conversion of outstanding debentures. The existence of
these outstanding warrants and options could adversely affect our ability to
obtain future financing. We have also reserved 2,250,000 shares of our common
stock for issuance in connection with the proposed settlement of outstanding
litigation. The consummation of this settlement will require satisfaction of a
number of conditions, and we cannot assure you that the settlement will be
completed.

                                       15
<PAGE>

         The price which we may receive for our common stock issued upon
exercise of outstanding options and warrants will likely be less than the market
price of our common stock at the time these options and warrants are exercised.
Moreover, the holders of the options and warrants might be expected to exercise
them at a time when we would, in all likelihood, be able to obtain needed
capital by a new offering of our securities on terms more favorable than those
provided for by the options and warrants.

OUR PREFERRED STOCK MAY DELAY OR PREVENT A TAKEOVER OF OUR COMPANY POSSIBLY
PREVENTING YOU FROM OBTAINING HIGHER SHARE PRICES.

         Our articles of incorporation authorize the issuance of 8,850,000
shares of "blank check" preferred stock, which will have terms as may be
determined from time to time by the board of directors. Accordingly, the board
of directors is empowered, without shareholder approval, to issue preferred
stock with terms which could adversely affect the rights of the holders of the
common stock. The preferred stock could also be utilized, under certain
circumstances, as a method of discouraging, delaying or preventing a change in
control of Premier. This could have the effect of preventing others from seeking
to acquire your shares in transactions at premium prices.

         In March 1998, we adopted a Shareholder Rights Plan, which entitles
certain of our shareholders to purchase our Series A Junior Participating
Preferred Stock. These rights are not exercisable until the acquisition by a
person or affiliated group of 15% or more of the outstanding shares of our
common stock, or the commencement or announcement of a tender offer or exchange
offer which would result in the acquisition of 15% or more of our outstanding
shares. Upon request, we will provide you with a copy of the Shareholder Rights
Plan. The Shareholder Rights Plan may have the effect of discouraging, delaying
or preventing a change of control of Premier.

SHORT SELLING OF OUR COMMON STOCK COULD ADVERSELY AFFECT OUR STOCK PRICE.

         If a significant number of shares of common stock which are issued upon
conversion of the debentures and payment of interest thereon are then sold in
the market, the price of our common stock could be depressed due to the presence
of these additional shares in the market. This downward pressure could encourage
short sales of common stock by the selling shareholders or others. By increasing
the number of shares offered for sale, material amounts of short selling could
place further downward pressure on the market price of the common stock.
