references in Sections 2.2(b)(ii), 2.2(b)(iv) and 2.2(b)(v) to the "number of 
Merger Securities" to be issued and to the "Per Share Value" shall be deemed 
to refer to the respective numbers of each type of Premier securities

                    (i)  Except as set forth in Section 2.2(c)(iv) below, 
EyeSys may, at its election, determine whether the securities so issuable 
shall be Premier Common Stock, Premier Class AA Options or Premier Class BB 
Options; provided, however, that unless waived by Premier in its sole 
discretion the maximum aggregate amount of Premier Class AA Options and 
Premier Class BB Options shall not exceed options to purchase 335,000 shares 
of Premier Common Stock.  

                   (ii)  Such securities shall be issuable under this Section
2.2(c) only if EyeSys shall, prior to or within 90 days of the Closing Date (the
"CONTINGENCY TERMINATION DATE"), execute a definitive license agreement with
Nidek Company, Ltd. and/or Marco Ophthalmic, Inc., on terms reasonably
acceptable to Premier (the "FUTURE LICENSE AGREEMENTS"), and which provides for
the payment of at least 10% of the Future License Fees (as defined below) on or
prior to the Contingency Termination Date.  The aggregate amount of securities
issuable under this Section 2.2(c) (the "CONTINGENT CONSIDERATION") shall be
calculated by reference to the noncontingent license fees (the "FUTURE LICENSE
FEES") paid or payable to EyeSys under the Future License Agreements, which
amounts shall have been actually received by EyeSys before the Contingency
Termination Date or which are contractually required to be paid within one year
from the date hereof.  The value of the securities issuable under this Section
2.2(c) shall be equal to the sum of:  (i) .78 times the amount of the Future
License Fees, for the first $1,500,000 of such Future License Fees; plus (iii)
 .5 times the amount of the Future License Fees in excess of $1,500,000.

                  (iii)  For purposes of this Section 2.2(c), with respect to 
that amount of the Future License Fees which is received prior to the Closing 
Date, Premier Common Stock shall be valued at the Per Share Value used in 
connection with the Merger, and Premier Class AA Options and Premier Class BB 
Options shall be deemed to have the same value as Premier's outstanding 
publicly traded Class A Warrants and Class B Warrants computed in the same 
manner as the Per Share Value and over the same measuring periods, 
respectively, used in the calculation of the Per Share Value (but without 
adjustment for the differences in terms between such securities).  With 
respect to that amount of the Future License Fees which is received after the 
Closing Date, the Premier Common Stock, Premier Class AA Options and Premier 
Class BB Options shall be valued using the same measuring period selected by 
Premier in computing the Per Share Value, but substituting the date of 
receipt of such additional Future License Fees for the date of the "Closing" 
in such definition.

                   (iv)  In no event shall Premier be obligated to issue 
Premier Common Stock under this Section 2.2(c) if the total number of shares 
so issuable, when taken together with all other Premier Common Stock issued 
in connection with the Merger, shall exceed the maximum number of shares 
issuable in the Merger without the approval of the Merger by Premier 
shareholders in accordance with the California Corporations Code (the 
"MAXIMUM AMOUNT"); provided, however, that in the event the number of shares 
of Premier Common Stock issuable hereunder exceeds the Maximum Amount, 
Premier shall have the option of delivering, in lieu of the shares that would 
be in excess of the Maximum Amount, either cash, Premier Class AA Options or 
Premier Class BB Options, such that the total amount of consideration paid by 
Premier hereunder is equal to the amount required to be paid under Section 
2.2(c)(ii) above.

                                        -11-



                    (v)  If any part of the Future License Fees with respect 
to which the Contingent Consideration has been calculated is not paid when 
due by the party obligated to pay such amounts, then the Contingent 
Consideration shall be recalculated using the amount of Future License Fees 
actually received within the one-year period after the Closing Date and the 
Per Share Value and/or warrant prices specified in Section 2.2(c)(iii) used 
to calculate the number of shares or options issued in the Contingent 
Consideration (the "ORIGINAL VALUES"), and the excess of the amount of 
Contingent Consideration actually paid or delivered over the amount of 
Contingent Consideration as recalculated shall be reimbursed to Premier out 
of the Escrow Shares (using the Original Values). Section 2.3 shall govern 
the reallocation of the Merger Securities among the holders of Interests in 
EyeSys, in the event that Merger Securities shall  be returned to Premier out 
of the Escrow pursuant to this Section 2.2(c)(v). 

               (d)  The conversion of the EyeSys Notes and exchange of Merger 
Securities for Nonincluded Costs (other than Stay Bonuses) shall be effected 
at the Closing.  The amount and type of securities into which the Interests 
in EyeSys (other than the EyeSys Notes) shall be converted hereunder shall be 
calculated immediately after the Contingency Termination Date, when the total 
amount of the Contingent Consideration is known.  Accordingly, within 3 
business days after the Contingency Termination Date, the EyeSys 
Representative selected pursuant to Section 9.13 shall notify Premier of the 
type of securities EyeSys has elected to issue under Section 2.2(c)(i), and 
shall calculate the total amount and type of the securities issuable 
hereunder and shall notify Premier in writing of such calculation.  Premier 
shall have 3 business days from the receipt of such notice to review the 
calculations contained therein, and unless Premier gives the EyeSys 
Representative notice in writing within such 3 day period of Premier's 
disapproval of such calculation, it shall be deemed final, absent manifest 
error. If Premier disapproves such calculation, it shall provide the EyeSys 
Representative with written notice of the reasons for such disapproval.  The 
parties shall thereafter confer in a good faith effort to resolve such 
dispute.  If such dispute cannot be resolved within two weeks after the date 
of Premier's notice of disapproval, the matter shall be submitted to binding 
arbitration in accordance with the procedures set forth in the Escrow 
Agreement.  After the allocation of the Merger Securities has been agreed 
upon, or determined according to such arbitration procedures, Premier shall 
promptly forward certificates representing the Merger Securities, in 
accordance with such allocation.

               (e)  For purposes of this Section 2.2(e) only, the Premier 
Options included in the Shareholder Consideration shall be deemed to have a 
value of $3.00 per option.  Premier shall issue to the holders of all 
then-outstanding EyeSys Options and EyeSys Common Warrants, and to the 
persons entitled to the Stay Bonuses, an aggregate of 165,000 Premier 
Options, as follows:

                    (i)  The value of outstanding and unexercised EyeSys 
Options shall be equal to the value of the EyeSys Common Stock issuable upon 
exercise thereof (using the Per Share Value of the Premier Common Stock into 
which such EyeSys Common Stock would be converted in this Merger), less the 
exercise price of such options.  Each EyeSys Option shall be exchanged for 
that number of Premier Options as is equal to the value determined under the 
foregoing sentence, divided by $3.00.  In the event that the Contingent 
Consideration is payable hereunder and there are no further Premier Options 
issuable in exchange for the full value of an Eyesys Option, determined in 
accordance with the second 

                                        -12-



preceding sentence, then the holder thereof shall be entitled to receive the 
balance of such value in Merger Securities.

                    (ii)  If any Premier Options remain after EyeSys Options 
are exchanged under Section 2.2(e)(i) above, the remaining Premier Options 
shall then be issued in exchange for outstanding EyeSys Common Warrants.  
Each outstanding and unexercised EyeSys Common Warrant shall be exchanged for 
that number of Premier Options as is equal to the value of the EyeSys Common 
Stock issuable upon the "net exercise" thereof (using the Per Share Value of 
the Premier Common Stock into which such EyeSys Common Stock would be 
converted in this Merger), divided by $3.00.  In the event that the 
Contingent Consideration is payable hereunder and there are no further 
Premier Options issuable in exchange for the full value of an EyeSys Common 
Warrant, determined in accordance with the second preceding sentence, then 
the holder thereof shall be entitled to receive the balance of such value in 
Merger Securities.

                   (iii)  If any Premier Options remain after the application 
of sections 2.2(e)(i) and 2.2(e)(ii) above, the remaining Premier Options 
shall be issued to the persons entitled to the holders of the Stay Bonuses, 
in satisfaction of such Stay Bonuses, at the rate of $3.00 of Stay Bonus 
forgiven for each Premier Option so issued.  EyeSys shall determine which 
persons shall receive Premier Options under this Section 2.2(e)(iii).

                    (iv)  EyeSys shall make arrangements for agreements with 
the holders of the EyeSys Options and EyeSys Common Warrants and the persons 
entitled to the Stay Bonuses to exchange such securities or claims for the 
Premier Options in accordance with this Section 2.2(e), and for the 
termination of any EyeSys Option or EyeSys Common Warrant, or payment of any 
Stay Bonus, that is not exchanged or paid as set forth above.  Premier will 
issue the Premier Options within three (3) business days after the 
determination of the allocation of the Merger Securities as set forth in 
Section 2.2(d).

               (f)  Notwithstanding anything herein, with respect to each 
holder of Interests in EyeSys, if the aggregate number of shares of Premier 
Common Stock collectively issuable to such a holder for conversion of all of 
such holder's EyeSys Common Stock, Preferred Stock and EyeSys Notes pursuant 
to Section 2.2(b) includes a fractional share, such fractional share shall be 
rounded to the nearest whole number.  The aggregate number of shares of 
Premier Common Stock purchasable under Premier Options issued in exchange for 
EyeSys Options and EysSys Common Warrants shall be rounded to the nearest 
whole number and the aggregate exercise price (but not the exercise price per 
share thereof) shall be adjusted accordingly.  To the extent that any of the 
holders of Interests in EyeSys have presently outstanding rights to purchase 
shares of EyeSys capital stock that expire in whole or in part unexercised, 
the exchange ratios set forth above with respect to the exchange of Interests 
in EyeSys into shares of Premier Common Stock or Premier Options shall not be 
adjusted after the Effective Time of the Merger.  All shares of EyeSys Common 
Stock or EyeSys Preferred Stock that are owned by EyeSys shall be canceled, 
and no securities of Premier or other consideration shall be delivered in 
exchange therefor.

               (g)  At the Effective Time, by virtue of the Merger and 
without any action on the part of any shareholder of PAI, each issued and 
outstanding share of capital stock 

                                        -13-



of PAI shall continue to be issued and shall be converted into one share of 
Common Stock of EyeSys, as the surviving corporation in the Merger.  Each 
stock certificate of PAI evidencing ownership of any such shares shall 
continue to evidence ownership of such shares of capital stock of EyeSys, as 
the surviving corporation in the Merger.

          2.3  ESCROW.

               (a)  Twenty percent of all securities otherwise issuable in 
respect of EyeSys Common Stock, Preferred Stock and the EyeSys Notes pursuant 
to Sections 2.2(b) (collectively, the "ESCROW SHARES") shall be deducted from 
the Merger Shares on a pro rata basis among the holders of EyeSys Common 
Stock, Preferred Stock and the EyeSys Notes and placed in an escrow for a one 
(1)-year period as the source of payment for the indemnification obligations 
of EyeSys, pursuant to Article 7 of this Agreement and the Escrow Agreement.

               (b)  In addition to the shares described in Section 2.3(a) 
above, there shall be deposited into the Escrow that number of shares of 
Premier Common Stock (the "ESCROWED DISSENTING SHARES") equal to the number 
of shares that would be issuable to any EyeSys stockholders who have 
perfected their Appraisal Rights at the Closing Date in accordance with 
Delaware law.  To the extent that the Principal Shareholder sells shares of 
Premier Common Stock under Section 5.22, the Escrowed Dissenting Shares so 
deposited in the Escrow shall be immediately released to the Principal 
Shareholder, in an amount equal to the amounts of Premier Common Stock sold 
by it, and shall be subject to the Lock-Up Agreement executed by the 
Principal Shareholder.  At such time as the claims of dissenting shareholders 
have been paid, all of the Escrowed Dissenting Shares that have not been 
released to the Principal Shareholder shall be returned to Premier.  The 
Interests in Eyesys held by the Principal Shareholder shall be deemed 
converted, upon consummation of the Merger, into the right to receive that 
number of the Escrowed Dissenting Shares required to be delivered under this 
Section 2.3(b).

               (c)  Upon the distribution out of the Escrow of any remaining 
securities to the holders of Interests in EyeSys, such securities shall be 
distributed to such holders in such amounts as would provide such holders 
with that amount of the Merger Securities that they would have received under 
Section 2.2(b) had the aggregate amount of Merger Securities originally 
issued been only the total amount of Merger Securities outstanding after any 
reimbursement to Premier of Merger Securities required to be made under this 
Agreement.

          2.4  THE CLOSING.  Subject to termination of this Agreement as 
provided in Article 8 below, the closing of the Merger shall take place at 
the offices of Rutan & Tucker, 611 Anton Boulevard, Suite 1400, Costa Mesa, 
California 92626, at 10:00 a.m. on the business day that is three (3) 
business days after the Merger has been approved by the EyeSys shareholders, 
or such other place, time and date as Premier, PAI and EyeSys may mutually 
select (the "CLOSING").

          2.5  EFFECTIVE TIME.  Upon the complete satisfaction or satisfactory
waiver of all conditions set forth in Article 6 of this Agreement, the
Certificate of Merger shall be executed and filed as set forth herein. 
Simultaneously with the Closing, the Certificate of Merger shall be submitted
for filing in the office of the Secretary of State for the State of 


                                        -14-



Delaware. The Merger shall become effective immediately upon the filing of 
the Certificate of Merger in the office of the Secretary of State for the 
State of Delaware (the "EFFECTIVE TIME").

          2.6  REGISTRATION RIGHTS.

               (a)  The Merger Shares, the Premier Options, the Premier Class 
AA Options, the Premier Class BB Options, the securities issuable upon 
exercise of any of such options and the Cowen Shares shall be registered, 
pursuant to the Registration Statement to be filed with the Securities and 
Exchange Commission.  EyeSys shall furnish its shareholders with a Proxy 
Statement/Prospectus for a special meeting of the shareholders of such 
company, to be held on or about June 15, 1997, or as soon thereafter as is 
practicable.

               (b)  EyeSys shall provide Premier with such audited financial 
statements and other information concerning EyeSys (including updated 
financial information, if required by applicable securities laws) as may be 
required in order to accurately prepare the Registration Statement, and 
Premier shall have no obligation to file the Registration Statement until 
such information has been provided.

          2.7  RESTRICTIONS ON SECURITIES.  The Premier Common Stock, Premier
Class AA Options, Premier Class BB Options, and Premier Options issued to
certain holders of Interests in EyeSys shall be subject to the following
agreements:

               (a)  the Lock-Up Agreement, executed by the EyeSys 
stockholders listed on Schedule 2.7 (the "EYESYS STOCKHOLDERS") in the forms 
attached hereto as EXHIBIT C-1 (for holders of 5% or more of the EyeSys 
Shares, on an as-converted basis) or EXHIBIT C-2 (for holders of less than 5% 
of the EyeSys Shares, on an as-converted basis) (collectively, the "EYESYS 
LOCK-UP AGREEMENTS"); and

               (b)  the Escrow Agreement.

          2.8  SURRENDER AND EXCHANGE OF OUTSTANDING CERTIFICATES, PREMIER
WARRANTS FOR EYESYS WARRANTS AND PREMIER OPTIONS FOR EYESYS OPTIONS; STATUS OF
OUTSTANDING CERTIFICATES.  The conversion of the EyeSys Notes, the EyeSys Common
Stock and Preferred Stock into the right to receive Merger Shares and additional
securities under Section 2.2(d), as provided for by this Agreement, shall occur
automatically at the Effective Time without further action by the holders
thereof.  Until surrendered, each certificate that prior to the Effective Time
represented shares of EyeSys Common Stock and Preferred Stock, as well as each
EyeSys Note, will be deemed to evidence the right to receive the number of
shares of Premier Common Stock or additional securities into which such EyeSys
Common Stock, Preferred Stock or EyeSys Note have been converted.  Premier
shall, within ten (10) business days after the Effective Time, use reasonable
efforts to notify each holder of a certificate or certificates theretofore
representing a share or shares of EyeSys Common Stock, Preferred Stock and
EyeSys Notes to surrender all of such holder's certificates or EyeSys Notes, as
the case may be, to Premier; and upon such surrender such holder shall be
entitled to receive in exchange a certificate or certificates representing the
Premier Common Stock into which such shares or EyeSys Notes have been converted.


                                        -15-



          2.9  APPRAISAL RIGHTS.  Holders of EyeSys Common Stock or Preferred
Stock who have complied with all requirements for perfecting the appraisal
rights as set forth in the Delaware General Corporation Law shall be entitled to
their rights under such laws.  EyeSys shall give Premier prompt written notice
of any written demands for appraisal, withdrawals of demands for appraisal and
any other instrument in respect thereof received by EyeSys.

          2.10 REORGANIZATION.  The parties intend to adopt the Agreement as a
plan of reorganization and to consummate the Merger in accordance with
Section 368(a) of the Code.  To the best of its knowledge, EyeSys believes that
(a) the fair market value of the Merger Shares and other consideration received
by each EyeSys shareholder from Premier in respect of the Merger is
approximately equal to the fair market value of the Interests in EyeSys
surrendered in the exchange, and (b) that the fair market value of the assets of
EyeSys after the Effective Time will equal or exceed the sum of the liabilities
to which the transferred assets are subject.

          2.11 ARTICLES AND CERTIFICATE OF INCORPORATION; BYLAWS; DIRECTORS AND
OFFICERS OF PREMIER AND THE SURVIVING CORPORATION. 

               (a)  The Articles of Incorporation of Premier as in effect as 
of the date of this Agreement shall be the Articles of Incorporation of 
Premier after the Merger, unless and until thereafter amended.  The 
Certificate of Incorporation of EyeSys, modified as indicated in the 
Certificate of Merger, shall be the Certificate of Incorporation of EyeSys as 
the surviving corporation after the Merger, unless and until thereafter 
amended.

               (b)  The Bylaws of Premier as in effect immediately prior to 
the Effective Time shall be the Bylaws of Premier after the Merger, unless 
and until thereafter amended.  The Bylaws of PAI in effect immediately prior 
to the Merger shall be the Bylaws of EyeSys as the surviving corporation 
after the Merger, unless and until thereafter amended.

               (c)  The directors and officers of Premier immediately 
following the Effective Time of the Merger shall be the same as the directors 
and officers of Premier immediately prior to the Merger, until their 
successors are elected or appointed and qualified, except as set forth in 
Section 5.15.

               (d)  The officers of EyeSys as the surviving corporation 
immediately following the Effective Time of the Merger shall be as follows 
until their successors are elected or appointed and qualified:

          Rom Rao             President and Director

          Michael Hiebert     Secretary and Chief Financial Officer

The directors of EyeSys as the surviving corporation immediately following the

                                      ARTICLE 3

                        REPRESENTATIONS AND WARRANTIES OF EYESYS

          Except as set forth in the EyeSys Letter, which disclosures shall be
deemed representations and warranties hereunder, EyeSys represents and warrants
to Premier and PAI as follows:

          3.1  ORGANIZATION AND STANDING.

               (a)  EyeSys is a corporation duly organized, validly existing 
and in good standing under the laws of the State of Delaware, has all 
requisite corporate power and authority to own, operate and lease its 
properties and carry on its business as now conducted, and is duly qualified 
to do business and is in good standing as a foreign corporation in each 
jurisdiction in which the failure to so qualify would have a Material Adverse 
Effect.

               (b)  EyeSys has delivered to Premier and PAI complete and 
accurate copies of its current Certificate of Incorporation and Bylaws, and 
minutes of all of its directors' and shareholders' meetings.  EyeSys' stock 
books provided to Premier and PAI are complete and accurate as of the date 
hereof

          3.2  CAPITALIZATION.

               (a)  EyeSys' current outstanding capitalization (common stock, 
preferred stock, warrants and options and any other issued or granted 
security) is as set forth in the EyeSys Letter.  The EyeSys Letter accurately 
describes the vesting schedules associated with EyeSys Options and states the 
number of shares of EyeSys Common Stock which may be acquired pursuant to 
unvested EyeSys Options.  EyeSys has advised Premier in writing of the 
residence of any holder of an Interest in EyeSys if such residence is outside 
of the United States.  EyeSys does not have in effect any stock appreciation 
rights plan and no stock appreciation rights are currently outstanding.

               (b)  Other than as set forth in the EyeSys Letter, EyeSys does 
not have outstanding any preemptive or subscription rights, options, 
warrants, rights to convert, capital stock equivalents or other  rights to 
purchase or otherwise acquire any of EyeSys' capital stock or other 
securities.

               (c)  All of the issued and outstanding shares of EyeSys Common 
Stock and EyeSys Preferred Stock have been duly authorized and validly issued 
and are fully paid and non-assessable, and such common and preferred stock 
has been issued in full compliance with all applicable federal and state 
securities laws.  All of EyeSys' incentive stock options have been issued in 
compliance with all laws, rules and regulations necessary to preserve such 
incentive stock option treatment.  All EyeSys Options have been issued in 
accordance with EyeSys' current stock option plan.

               (d)  Except for any restrictions imposed by applicable state 
and federal securities laws, and except as set forth in the EyeSys Letter, 
there is no right of first refusal, 


                                        -17-



co-sale right, right of participation, right of first offer, option or other 
restriction on transfer applicable to any shares of EyeSys Common or 
Preferred Stock.

               (e)  Except as set forth in the EyeSys Letter, (i) none of the 
holders of EyeSys Option or EyeSys Warrants has registration rights, and (ii) 
EyeSys is not and will not be under any obligation to register under the 
Securities Act any shares of EyeSys Common or Preferred Stock or any other of 
its securities that might be issued in the future if the Merger were not 
consummated.

               (f)  Except as set forth in the EyeSys Letter, EyeSys is 
neither a party nor subject to any agreement or understanding, and, to 
EyeSys' knowledge, there is no agreement or understanding between or among 
any persons that affects or relates to the voting or giving of written 
consent with respect to any security.

               (g)  Except as set forth in the EyeSys Letter, there have
not been and nor are there outstanding any adjustments made or required to be
made to the conversion prices of the Preferred Stock from those set forth in
EyeSys' Restated Certificate of Incorporation (the "EYESYS CERTIFICATE OF
INCORPORATION").  The number of Merger Securities into which each share of
EyeSys Common Stock, Preferred Stock and the EyeSys Notes convert pursuant to
Section 2.2 of this Agreement is consistent with that which the holders of the
respective Interests in EyeSys are entitled to under the amendments to the
EyeSys Notes and the First Amendment to the Restated Certificate of
Incorporation of EyeSys.  Upon obtaining the approvals and consents described in
Section 2. 1 (a) of this Agreement, (i) the EyeSys Notes shall have been duly
amended and such amended EyeSys Notes shall be the legal, valid and binding
obligation of EyeSys and the holders of the EyeSys Notes, and (ii) the First
Amendment to the Restated Certificate of Incorporation of EyeSys shall have been
duly adopted in accordance with Delaware Law upon the filing with the Secretary
of State for the State of Delaware.

          3.3  SUBSIDIARIES.  EyeSys neither owns nor controls, directly or
indirectly, any corporation, partnership, business, trust or other entity.

          3.4  AUTHORITY, APPROVAL AND ENFORCEABILITY.

               (a)  Subject to obtaining the approval of the holders of 
EyeSys Common Stock, Preferred Stock and the holders of the EyeSys Notes 
required pursuant to Section 2.1(a), EyeSys has full corporate power and 
authority to execute, deliver and perform its obligations under this 
Agreement and all corporate action on its part necessary for such execution, 
delivery and performance has been duly taken.

               (b)  Subject to obtaining all necessary consents, the 
execution and delivery by it of this Agreement do not, and the performance 
and consummation of the transactions contemplated by this Agreement shall 
not, result in any conflict with, breach or violation of or default, 
termination or forfeiture under (or upon the failure to give notice or the 
lapse of time, or both, result in any conflict with, breach or violation of 
or default, termination or forfeiture under) any terms or provisions of the 
EyeSys Certificate of Incorporation, the First Amendment to the Restated 
Certificate of Incorporation of EyeSys or its Bylaws, or any statute, rule, 
regulation, judicial, governmental, regulatory or administrative decree, 
order or judgment, or 

                                        -18-



any agreement, lease, license, permit or other instrument to which it is a 
party or to which any of its assets is subject, the breach, violation, 
default, termination or forfeiture of which could or would result in a 
Material Adverse Effect.

               (c)  No consent, approval, authorization, order, registration, 
qualification or filing of or with any court or any regulatory authority or 
any other governmental or administrative body is required on its part for the 
consummation by it of the transactions contemplated by this Agreement, except 
the filing of the First Amendment to the Restated Certificate of 
Incorporation of EyeSys and the Certificate of Merger in the office of the 
Secretary of State of the State of Delaware.

               (d)  Subject to Premier, PAI and EyeSys obtaining the 
approvals identified in Section 2.1, this Agreement is the legal, valid and 
binding obligation of EyeSys, enforceable against EyeSys in accordance with 
its terms, except as may be limited by applicable bankruptcy, insolvency, 
reorganization, moratorium or similar laws affecting creditors' rights 
generally and subject to the availability of equitable remedies.

          3.5  FINANCIAL STATEMENTS.

               (a)  Except as set forth in the EyeSys Letter, EyeSys has 
delivered to Premier and PAI complete copies of its consolidated balance 
sheets as at December 31 for calendar years 1991 through 1995 and the related 
statements of operations, shareholders' equity and cash flows for the 
calendar years 1990 through 1995 and the notes thereto, accompanied by the 
auditors' report containing the unqualified opinion of its independent 
certified public accountants.  Prior to the Closing, EyeSys shall deliver to 
Premier and PAI a complete copy of its consolidated balance sheets as at 
December 31, 1996, and the related statements of operations, shareholders 
equity and cash flows for the calendar year 1996 and the notes thereto, 
accompanied by the auditor's report containing the opinion of its independent 
certified public accountants, containing a "going concern" qualification (the 
"1996 FINANCIALS").  The financial statements described above are referred to 
herein, collectively as the "AUDITED FINANCIALS."  EyeSys' Audited Financials 
are (or, with respect to the 1996 Financials, will be) complete and correct 
in all material respects and present fairly its consolidated financial 
position as of those dates and the results of its operations and cash flows 
for the years then ended, in conformity with GAAP applied on a consistent 
basis.

               (b)  EyeSys has delivered to Premier and PAI an unaudited 
consolidated balance sheet as of December 31, 1996 and the related unaudited 
statements of operations, shareholders' equity and cash flows for the twelve 
(12) months then ended (the "INTERIM FINANCIALS").  EyeSys' Interim 
Financials are complete and correct in all material respects (notwithstanding 
any annotations in the EyeSys Letter schedule of accounts receivable) and 
present fairly its financial condition as of December 31, 1996 and the 
results of its operations and cash flows for the twelve (12) months then 
ended, in conformity with GAAP applied on a basis consistent with its Audited 
Financials (except for the absence of notes thereto and subject to normal 
year-end audit adjustments, which are not material).  The Audited Financials 
and the Interim Financials are hereinafter collectively referred to as the 
"EYESYS FINANCIALS."

                                        -19-



               (c)  There are no debts, liabilities or claims against EyeSys 
as of the dates of the EyeSys Financials that are not currently reflected in 
such EyeSys Financials, contingent or otherwise, which are or would be of a 
nature required to be reflected in a balance sheet prepared in accordance 
with GAAP.  All deferred taxes of EyeSys are properly accounted for in the 
EyeSys Financials, in accordance with GAAP.  EyeSys' revenue recognition 
policies with respect to the EyeSys Financials have been made in accordance 
with GAAP.  All of EyeSys' general ledgers, books and records are located at 
EyeSys' principal place of business.  EyeSys does not have any of its 
records, systems, controls, data or information recorded, stored, maintained, 
operated or otherwise wholly or partly dependent upon or held by any means 
(including any electronic, mechanical or photographic process, whether 
computerized or not) that (including all means of access thereto and 
therefrom) are not under the exclusive ownership and direct control of EyeSys.

               (d)  Subject to any reserves set forth in the EyeSys 
Financials, all of the accounts receivable and notes receivable owing to 
EyeSys, as of the date hereof, constitute and as of the Effective Time will 
constitute, valid and enforceable claims arising from bona fide transactions 
in the ordinary course of business, and there are no known or asserted 
claims, refusals to pay, or other rights of set-off against any thereof.  
Except as set forth in the EyeSys Letter, there is (i) no account debtor nor 
note debtor delinquent in its payment by more than 60 days, (ii) no account 
debtor nor note debtor that has refused (or, to the best knowledge of EyeSys, 
threatened to refuse) to pay its currently outstanding obligations to EyeSys 
for any reason, (iii) to the best knowledge of EyeSys, no account debtor nor 
note debtor that is insolvent or bankrupt, and (iv) no account receivable nor 
note receivable pledged to any third party by EyeSys.

               (e)  Except for any Transaction Costs, all accounts payable 
and notes payable by EyeSys to third parties as of the date hereof arose, and 
as of the Closing will have arisen, in the ordinary course of business, and, 
there is no such account payable nor note payable delinquent in its payment, 
except as set forth in the EyeSys Letter, or any update thereto prior to the 
Closing.

          3.6  MATERIAL CHANGES.  Since December 31, 1996, except as set forth
in the EyeSys Letter, there has not been:

               (a)  any material change in its assets, liabilities, financial 
condition, or operating results from that reflected in the Financials, except 
changes in the ordinary course of business that have not been, in the 
aggregate, material; nor any damage, destruction or loss, whether or not 
covered by insurance, materially adversely affecting its business, 
properties, prospects, or financial condition (as such business is presently 
conducted and as it is proposed to be conducted);

               (b)  any waiver or compromise by it of a valuable right or of 
a debt owed to it; nor any satisfaction or discharge of any lien, claim, or 
encumbrance or payment of any obligation by it, except in the ordinary course 
of business and that is not material to its business, properties, prospects, 
or financial condition (as such business is presently conducted and as it is 
proposed to be conducted);

                                        -20-



               (c)  any material change to a material contract or material 
arrangement by which it or any of its material assets is bound or subject; 
any material change in any compensation arrangement or agreement with any 
employee, consultant, officer, director or shareholder; any sale, assignment, 
or transfer of any patents, trademarks, copyrights, trade secrets, or other 
intangible assets; nor notification that there has been a loss of or material 
order or contract cancellation by any of its customers;

               (d)  any resignation or termination of employment of any of 
its key officers or employees; and EyeSys, to the best of its knowledge, does 
not know of the impending resignation or termination of employment of any 
such officer or employee;

               (e)  any mortgage, pledge, transfer of a security interest in, 
or lien created by it, with respect to any of its material properties or 
assets, except liens for taxes not yet due or payable; any loans or 
guarantees made by it to or for the benefit of its employees, officers, or 
directors, or any members of their immediate families, other than travel 
advances and other advances made in the ordinary course of its business; nor 
any declaration, setting aside or payment or other distribution in respect of 
any of its capital stock, nor any direct or indirect redemption, purchase, or 
other acquisition of any of such stock by it;

               (f)  any other event or condition of any character that would 
result in a Material Adverse Effect; nor (other than in the ordinary course 
of business) any agreement or commitment by it to do any of the things 
described in this Section 3.6.

          3.7  RETURNS.  EyeSys has not had any of its products returned by a 
purchaser or user thereof other than for minor, nonrecurring warranty 
problems. Except as set forth in the EyeSys Letter, EyeSys is not aware of 
any pending warranty claims.  The reserves reflected on the EyeSys Financials 
for future warranty claims are adequate to provide for future warranty claims 
on products sold by EyeSys through the date of the EyeSys Financials.

          3.8  PROPERTIES AND INVENTORIES.

               (a)  EyeSys has good and marketable title to and the right to 
use all of the assets used in its operations or necessary for the conduct of 
its business, as reflected in the EyeSys Financials, free and clear of any 
mortgages, pledges, security interests, licenses, encumbrances, restrictions 
or adverse claims, except as disclosed in the notes to its Financials, except 
for the lien of taxes not yet due and payable, and except as set forth in the 
EyeSys Letter.  All of the physical assets reflected on its balance sheets 
included in the EyeSys Financials are valued therein at the lower of fair 
market value or the amount computed under other EyeSys financial reporting 
policies (and, for such purposes, taking into account any obsolescence of 
such assets), are in the possession of EyeSys, and will be in the possession 
of EyeSys at the Closing (except for inventory sold in the ordinary course of 
business).  All of such physical assets are in good operating condition, 
normal wear and tear excepted. 

               (b)  Since September 30, 1996, there has not occurred any 
transfer of title other than in the ordinary course of business, any 
abandonment, any pilferage or any other material loss with respect to, any of 
its property, plant or equipment.


                                        -21-



               (c)  Included in the EyeSys Letter is a true and correct list 
of all of the physical assets (including fixed assets) owned by EyeSys having 
a net book value in excess of $5,000.  EyeSys does not own any real property. 
 All improvements on leased property used in the business of EyeSys and the 
present use thereof are in accordance with all applicable laws.  The net book 
value of any fixed assets owned by EyeSys has not been written up nor down, 
other than pursuant to depreciation or amortization expense in accordance 
with its historical practice.

               (d)  The EyeSys Letter lists all real property leases to which 
EyeSys is a party.  Assuming due authorization, execution and delivery by the 
other parties thereto, such leases are legal, valid, binding and enforceable 
in accordance with their respective terms (except as limited by bankruptcy, 
insolvency, reorganization or other laws of general application affecting 
creditors' rights generally).  EyeSys has a valid and subsisting leasehold 
interest in its leased real property, free and clear of all material 
encumbrances.  Neither EyeSys nor, to the knowledge of EyeSys, any other 
party to any of such leases, is in material default under any of such leases, 
or has performed any act or omitted to perform any act which act or omission, 
with notice or lapse of time or both, will become a material default 
thereunder.

          3.9   INSURANCE.  EyeSys maintains policies of insurance covering 
its assets, properties, business and liabilities in types and amounts 
customary for similarly sized companies engaged in similar businesses.  
EyeSys is in compliance with each of such policies, such that none of the 
coverage provided under such policies has been invalidated.  EyeSys has fully 
paid all premiums and other payments which have become due to its insurers.  
The EyeSys Letter contains a complete and accurate list of all insurance 
policies, bonds and surety instruments.  To the knowledge of EyeSys, there is 
no threat by any of the insurers to terminate or materially increase the 
premiums payable under any of such insurance policies due to the activities 
or loss experience of EyeSys.

          3.10  PURCHASE, SALE AND OTHER AGREEMENTS.

                (a)  Except as described in the EyeSys Letter, EyeSys is not

or 

                    (xi)  agreements of indebtedness, capital equipment leases
or guarantees of the obligations of others.

                (b)  To the best of EyeSys' knowledge, except as set forth in 
the EyeSys Letter, no party to any such contract, agreement or arrangement 
intends to cancel, withdraw, modify or amend such agreement or arrangement or 
return a product for reimbursement or discontinue any provision of 
agreed-upon services.

                (c)  Except as described in the EyeSys Letter, EyeSys has 
performed all material obligations required to be performed by it on or prior 
to the date hereof under each contract, obligation, commitment, agreement, 
undertaking, arrangement or lease referred to in this Agreement (including, 
without limitation, the Loan Agreement) or the EyeSys Letter, and it is not 
in default, breach nor violation thereunder, or under any other agreements to 
which it is a party, except for such defaults, breaches, or violations under 
such instruments or obligations that would not have a Material Adverse Effect.


                                        -23-


          3.11 INTELLECTUAL PROPERTY RIGHTS.

               (a)  EyeSys has complete and undisputed title and ownership 
and the right to utilize all patents, trademarks, license rights, service 
marks, trade names, copyrights, trade secrets, information, proprietary 
rights and processes (collectively, "INTELLECTUAL PROPERTY") necessary for or 
used in its business as now conducted and as proposed to be conducted without 
any conflict with or infringement of the rights of others.  All of EyeSys' 
patents, trademarks, license rights, service marks, trade names and 
copyrights, whether or not registered, are identified in the EyeSys Letter.  
Except as disclosed in the EyeSys Letter, there are no outstanding options, 
licenses, or agreements of any kind relating to the foregoing, nor is it 
bound by or a party to any options, licenses or agreements of any kind with 
respect to the Intellectual Property of any other person or entity.  It has 
not received any communications nor is it aware of any entity alleging that 
it has violated or, by conducting its business as proposed, would violate any 
Intellectual Property of any other person or entity.  It is not aware that 
any of its employees or consultants is obligated under any contract 
(including licenses, covenants or commitments of any nature) or other 
agreement, or subject to any judgment, decree or order of any court or 
administrative agency, that would interfere with the use of his or her best 
efforts to promote the interests of EyeSys or that would conflict with its 
business as proposed to be conducted.  EyeSys does not believe it is or will 
be necessary to utilize any inventions of any of its employees or consultants 
(or persons it currently intends to hire as service providers) made prior to 
their employment by it.  The EyeSys Letter sets forth all patents, patent 
applications, trademarks (registered or unregistered), license agreements, 
independent contractor or consulting agreements and any other Intellectual 
Property that requires a consent or waiver to consummate the transactions 
contemplated in this Agreement.  All of EyeSys' license agreements with 
respect to its Intellectual Property are in writing and evidence legitimate 
ownership of such rights in EyeSys.  All royalty obligations of EyeSys are 
listed in the EyeSys Letter.  No claims for royalties have been, are or will 
be asserted against EyeSys.  No invention that is shown as being owned by any 
individual service provider of EyeSys is necessary for the conduct of EyeSys' 
business.

               (b)  EyeSys is not making use of any confidential information 
of third parties nor any confidential information in which any of its present 
or, to its actual knowledge, past employees or other service providers, has 
claimed a proprietary interest; and EyeSys is not actually aware of any facts 
that would give rise to such a claim.

               (c)  Without limiting the generality of the foregoing 
representations, except as described in the EyeSys Letter, EyeSys expressly 
represents and warrants that:

                    (i)  EyeSys has satisfied all obligations pursuant to any
and all consulting agreements;

                   (ii)  EyeSys has no present or future liability under any
agreement to (x) provide indemnification for infringement of any third-party
rights or otherwise; or (y) provide updates, enhancements, modifications, bug
fixes, support, maintenance or the like of any products, or technology;


                                        -24-



                  (iii)  Except as disclosed in the EyeSys Letter, as of the
date of this Agreement, EyeSys has not entered into nor negotiated with others
to enter into any consulting agreements, software development agreements,
license agreements or similar agreements; 

                   (iv)  EyeSys has retained all rights, title and interest
(including, without limitation, rights to derivatives, modifications, updates
and enhancements) to the components necessary for its business as now conducted
and as proposed to be conducted in the future;

                    (v)  EyeSys knows of no facts or circumstances which would
materially and adversely affect the validity or enforceability of any of its
patents, trademarks, or copyrights;

                   (vi)  All fees and filings necessary to keep the patents,
copyrights and trademarks of EyeSys in full force and effect, including without
limitation, patent maintenance fees and annuity fees, have been duly and
properly paid or executed;

                  (vii)  All applications of EyeSys for patents, trademark
registrations and copyright registrations were properly filed in compliance with
the applicable laws of the countries in which they were filed;

                 (viii)  All information known to EyeSys to be material to the
patentability of the claims of EyeSys' U.S. patents and U.S. patent applicable
was submitted to the United States Patent and Trademark Office in accordance
with the duty of candor and good faith set forth in 37 C.F.R. Section 1.56;

                   (ix)  EyeSys has taken reasonable precautions to safeguard
the confidentiality of its trade secrets;

                    (x)  All copyrightable material used in EyeSys products
were either authored solely by employees of EyeSys within the scope or their
employment or authored by nonemployees with the copyright rights assigned in
writing to EyeSys; and

                   (xi)  The manufacturing, distribution, promotion and/or
activities of EyeSys as its business is presently conducted or proposed to be
conducted, does not violate any intellectual property rights, including without
limitation patent rights, of any other person or entity.

          3.12 EMPLOYEES AND EMPLOYEE BENEFIT PLANS.

               (a)  Other than as set forth in the EyeSys Letter regarding 
employee benefit plans, programs or arrangements maintained or sponsored by 
EyeSys (such plans, the "EMPLOYEE PLANS"), neither EyeSys nor any entity or 
trade or business which together with EyeSys is treated as a single employer 
under Sections 414(b), (c), (m) or (o) of the Code (its "ERISA AFFILIATES") 
is a party to any pension, profit sharing, savings, retirement or other 
deferred compensation plan, any bonus (whether payable in cash or stock), 
stock option, stock 


                                        -25-



purchase or incentive program, or any group health plan (whether insured or 
self-funded), or any disability or group life insurance plan, severance or 
other employee benefit plan (as defined in Section 3(3) of the Employee 
Retirement Income Security Act of 1974, as amended ("ERISA")), or to any 
collective bargaining agreement or other agreement, written or oral, with any 
trade or labor union, employees' association or similar organization.  EyeSys 
is not a party to, nor has made any contribution to or otherwise incurred any 
obligation under, any "multiemployer plan" as defined in Section 3(37) of 
ERISA.

          With respect to each such Employee Plan, EyeSys has furnished to 
Premier and PAI or their counsel complete and accurate copies of the plan 
documents (including plan amendments currently under consideration, trust 
documents, insurance policies or contracts, employee booklets, summary plan 
descriptions and other authorizing documents, and any material employee 
communications), and all IRS Forms 5500 filed with respect to any Employee 
Plans.

               (b)  With respect to each of the Employee Plans subject to 
ERISA as either an employee pension benefit plan within the meaning of 
Section 3(2) of ERISA or an employee welfare benefit plan within the meaning 
of Section 3(l) of ERISA, EyeSys has prepared in good faith and timely filed 
all requisite governmental reports, and has properly and timely posted or 
distributed all notices and reports to employees required to be filed, posted 
or distributed with respect to each such Employee Plan.

               (c)  Each such Employee Plan has at all times been operated 
and administered in all material respects in accordance with its terms and 
all applicable laws, including but not limited to, ERISA and the Code.

               (d)  Each Employee Plan that is intended to be qualified under 
Code Section 401(a) ("EYESYS PENSION PLAN") has received a favorable 
determination letter from the Internal Revenue Service that such Employee 
Plan is qualified under Code Section 401(a) and that the trust under such 
Employee Plan is exempt from tax under Code Section 501(a).  EyeSys knows of 
no reasonable basis for the disqualification of any EyeSys Pension Plan from 
exemption under Section 401(a) of the Code.

               (e)  Neither EyeSys nor any EyeSys Pension Plan, nor any 
fiduciary, trustee thereof nor, to the best knowledge of EyeSys, the 
administrator thereof or any party in interest (as defined in Section 3(14) 
of ERISA) or disqualified person (as defined in Section, 4975(e)(2) of the 
Code) with respect to such plan has engaged in any transaction which would 
subject EyeSys, the EyeSys Pension Plan, any trust created under such plan, 
or any trustee or administrator thereof, or any party dealing with such 
EyeSys Pension Plan or any such trust, to either civil liability or a civil 
penalty assessed pursuant to Section 409 or 502 of ERISA, or a tax imposed 
pursuant to Section 4975, 4976 or 4979 of the Code.  EyeSys has no knowledge 
of any breach of fiduciary duties owed to EyeSys Pension Plan participants 
pursuant to the provisions of Part 4 of Title I of ERISA.

               (f)  There are no pending claims by or on behalf of any of the 
EyeSys Employee Plans, by any employee or beneficiary covered under any such 
EyeSys Employee 

                                        -26-



Plan, or otherwise involving any such EyeSys Employee Plan (other than claims 
for benefits in the ordinary course).

               (g)  No EyeSys Pension Plan is subject to Section 412 of the
Code nor Title IV of ERISA.

               (h)  There are no strikes or labor disputes pending or 
threatened by nor any attempts at union organization of any EyeSys employees.

               (i)  The EyeSys Letter includes a full and complete list of 
all directors, officers and employees of EyeSys as of the date of this 
Agreement, specifying their names and job titles.  The EyeSys Letter provides 
accurate information to Premier and PAI regarding the total amount of base 
salary, whether it is fixed or commission or a combination thereof with 
respect to each of the foregoing.  Except as set forth in the EyeSys Letter, 
the employment of each of EyeSys' employees is "at will" employment, except 
as may be required to the contrary under applicable law.  Except as set forth 
in the EyeSys Letter, EyeSys does not have any obligation (i) to provide any 
particular form or period of notice prior to termination, or (ii) to pay any 
of such employees any severance benefits in connection with their termination 
of employment or service.  In addition, except as set forth in the EyeSys 
Letter, no severance pay will become due to any EyeSys employees under any 
EyeSys agreement, plan or program as a result of the Merger.  EyeSys does not 
owe and has not accrued any bonuses or vacation pay or retirement benefits to 
employees or former employees, other than as set forth on the payroll records 
delivered by EyeSys to Premier and PAI prior to the Closing.

               (j)  EyeSys has not violated any of the health care 
continuation coverage requirements of the Consolidated Omnibus Budget 
Reconciliation Act of 1985 ("COBRA") applicable to its employees prior to the 
Effective Time of the Merger.

          3.13 ENVIRONMENTAL AND SAFETY LAWS.  Except as described in the
EyeSys Letter, there are no Hazardous Substances (as hereinafter defined) at any
of the facilities owned or used by EyeSys.  The EyeSys Letter describes the way
in which EyeSys disposes of any Hazardous Substances used by it, including the
names and locations of any offsite storage or disposal facilities used by
EyeSys.  EyeSys has not released, discharged nor disposed of Hazardous
Substances on or under any of such facilities or on or under any premises
previously occupied by EyeSys during the period in which such facilities have
been owned or used by EyeSys.  The facilities owned or used by EyeSys do not now
contain, nor did such facilities or any premises previously occupied by EyeSys
contain, any underground storage tanks for any Hazardous Substances.  EyeSys has
complied and is in compliance with all applicable local, state and federal
environmental laws, regulations, ordinances and administrative and judicial
orders relating to the generation, recycling, use, sale, storage, handling,
transfer and disposal of any Hazardous Substances.  EyeSys has not been alleged
to be in violation of, nor been subject to any administrative, judicial or
regulatory proceeding pursuant to, such laws or regulations either now or any
time during the past twenty-four months.  No Claims have been or are currently
asserted against EyeSys nor, to EyeSys' knowledge, will be asserted against
EyeSys after the Effective Time, based on EyeSys' acts or failures to act prior
to the Effective Time with respect to Hazardous Substances.


                                        -27-



          3.14 PROPRIETARY INFORMATION AND INVENTIONS AND CONFIDENTIALITY 
AGREEMENTS.  Each employee, officer and director of EyeSys has executed a 
confidentiality agreement and all of the employees, officers and directors 
(not including non-employee directors) of EyeSys have executed a proprietary 
information and inventions agreement.  Copies of such agreements have been 
provided to counsel to Premier and PAI.  EyeSys is not aware that any of such 
persons is in violation thereof.

          3.15 POWERS OF ATTORNEY.  Except as set forth in the EyeSys Letter, 
no person holds a power of attorney from EyeSys.

          3.16 COMPLIANCE WITH LAWS AND PERMITS; REGULATORY MATTERS.  Except 
where the failure to so comply would not have a Material Adverse Effect, 
EyeSys has all valid and current permits, licenses, orders, authorizations, 
registrations, approvals and other analogous instruments (and each is in full 
force and effect) and EyeSys has made all filings and registrations and the 
like necessary or required by law to conduct its business as presently 
conducted. EyeSys has not received any governmental notice within two years 
of the date hereof of any violation by EyeSys of any such laws, rules, 
regulations or orders.  Except where the failure to comply would not have a 
Material Adverse Effect, (a) EyeSys is not in default or noncompliance under 
any such permits, consents, or similar instruments, and (b) the business and 
operations of EyeSys are in compliance with all foreign, federal, state, 
local and county laws, ordinances, regulations, judgments, orders, decrees or 
rules of any court, arbitrator or governmental, regulatory or administrative 
agency or entity. Without limiting the generality of the foregoing, all of 
the products presently marketed by EyeSys have been approved or cleared to 
market pursuant to valid and subsisting Premarket Approval or Section 510(k) 
Clearances issued by the United States Food and Drug Administration ("FDA").  
EyeSys has never conducted any clinical trials which have required 
Investigational Device Exemptions ("IDE's"). EyeSys is unaware of any medical 
complications arising in connection with or resulting from clinical trials 
conducted by EyeSys either directly or under its direction, or from the use 
of its products following FDA approval or clearance, except as set forth in 
the EyeSys Letter.  No complaints have been received by EyeSys with respect 
to such procedures, and no Medical Device Reports have been filed by EyeSys 
or have been required to be filed.  The design, manufacture and distribution 
of all of EyeSys' products has been conducted, and shall continue through the 
Closing Date to be conducted, in accordance with "good manufacturing 
practices" as required by the FDA.

          3.17 ABSENCE OF LITIGATION.  Except as disclosed in the EyeSys
Letter, neither EyeSys nor, to the best of its knowledge, any of its officers or
directors is engaged in, or has been threatened with, any litigation,
arbitration, investigation or other proceeding relating to it, its employee
benefit plans, property, business, assets, licenses, permits or goodwill, or
against or affecting the Merger or the actions taken or contemplated in
connection therewith, nor, to the best of its knowledge, is there any reasonable
basis therefor.  There is no action, suit, proceeding or investigation pending
or threatened against EyeSys that questions the validity of this Agreement or
the Agreement of Merger or the right of EyeSys to enter into this Agreement or
the Agreement of Merger or to consummate the transactions contemplated hereby or
thereby or which might result in any Material Adverse Effect.  The foregoing
includes actions pending or threatened (or any reasonable basis therefor known
to it) involving any dispute with its consultants or the prior employment of any
of its employees, their use in connection with its 


                                        -28-



business of any information or techniques allegedly proprietary to any of 
their former employers, or their obligations under any agreements with prior 
employers.  There is no action, suit, proceeding or investigation by EyeSys 
currently pending, nor which it intends to initiate.  Neither EyeSys nor, to 
the best of its knowledge, any of its officers or directors is bound by any 
judgment, decree, injunction, ruling or order of any court, governmental, 
regulatory or administrative department, commission, agency or 
instrumentality, arbitrator or any other person which would have a Material 
Adverse Effect.

          3.18  NO BROKERS.  Except with respect to the fees payable to Cowen 
which are included in the Transactional Costs, EyeSys is not obligated for 
the payment of fees or expenses of any broker or finder in connection with 
the origin, negotiation or execution of this Agreement or the Agreement of 
Merger nor in connection with any transaction contemplated hereby or thereby.

          3.19  THE REGISTRATION STATEMENT AND PROXY STATEMENT/PROSPECTUS.  
The information supplied by EyeSys for inclusion in the Registration 
Statement shall not at the time the Registration Statement is declared 
effective by the SEC contain any untrue statement of a material fact nor omit 
to state any material fact required to be stated therein or necessary in 
order to make the statements therein, in the light of the circumstances under 
which they were made, not misleading.  The information supplied by EyeSys for 
inclusion in the Proxy Statement/Prospectus to be sent to the holders of 
interests in EyeSys will not, on the date the Proxy Statement/Prospectus (or 
any amendment thereof or supplement thereto) is first mailed to holders of 
Interests in EyeSys, at the time of the EyeSys Stockholder Meeting, or at the 
Effective Time, contain any statement which, at such time and in light of the 
circumstances under which it shall be made, is false or misleading with 
respect to any material fact, or shall omit to state any material fact 
necessary in order to make the statement made therein not false or 
misleading.  If at any time prior to the Effective Time any event relating to 
EyeSys or any of its respective affiliates, officers or directors should be 
discovered by EyeSys which should be set forth in an amendment to the 
Registration Statement or a supplement to the Proxy Statement/ Prospectus, 
EyeSys shall promptly inform Premier and PAI.  The Proxy 
Statement/Prospectus, including all financial statements of EyeSys required 
to be included therein, shall comply in all material respects as to form with 
the requirements of the Securities Act, the Exchange Act and the rules and 
regulations thereunder.  Notwithstanding the foregoing, EyeSys makes no 
representation or warranty with respect to any information supplied or 
required to be supplied by Premier or PAI which is contained in any of the 
foregoing documents.

granted.  EyeSys will properly complete and file on a timely basis all 
Returns required to be filed on or prior to the Closing.

                (c)  With respect to all Taxes imposed upon EyeSys, or for 
which EyeSys is or was liable, whether to taxing authorities (as, for 
example, under law) or to other persons or entities (as, for example, under 
tax allocation agreements), with respect to all taxable periods or portions 
of periods ending on or before the date of Closing, EyeSys has fully complied 
with all applicable tax laws and agreements, and except as set forth in the 
EyeSys Letter, all such amounts required to be paid by EyeSys to taxing 
authorities, on or before the date of this Agreement, have been paid.  EyeSys 
does not owe any taxes on compensation paid to any of its employees.

                (d)  No issues have been raised (nor are currently pending) 
by any taxing authority in connection with any of the Returns.  No extensions 
nor waivers of statutes of limitations with respect to the Returns have been 
given by or requested from EyeSys.  Except to the extent indicated in the 
EyeSys Letter, all deficiencies asserted or assessments made as a result of 
any state or federal income tax examinations have been fully paid, or are 
fully reflected as a liability in the Financials of EyeSys, or are being 
contested and an adequate reserve therefor has been established and is fully 
reflected in the Financials of EyeSys.

                (e)  Except as set forth in the EyeSys Letter, there are no 
liens for Taxes (other than for current Taxes not yet due and payable) upon 
the assets of EyeSys.  EyeSys is not a party to or bound by (nor will EyeSys 
become a party to or bound by) any tax indemnity, tax sharing or tax 
allocation agreement.  EyeSys has never been a member of an affiliated group 
of corporations, within the meaning of Section 1504 of the Code.  EyeSys has 
not filed a consent pursuant to the collapsible corporation provisions of 
Section 341(f) of the Code (or any corresponding provision of state, local or 
foreign income Tax law) nor agreed to have Section 341(f)(2) of the Code (or 
any corresponding provision of state, local or foreign income Tax law) apply 
to any disposition of any asset owned by it.

                (f)  EyeSys has not elected to be treated as an S Corporation 
pursuant to Section 1362(a) of the Code.  None of the assets of EyeSys is 
property that EyeSys is 

                                        -30-



required to treat as being owned by any other person pursuant to the 
so-called "safe harbor lease" provisions of former Section 168(f)(8) of the 
Code.  None of the assets of EyeSys directly or indirectly secures any debt 
the interest on which is tax-exempt under Section 103 (a) of the Code.  None 
of the assets of EyeSys is "tax-exempt use property" within the meaning of 
Section 168(h) of the Code.

                (g)  EyeSys has not made and has not agreed to make a deemed 
dividend election under Treas. Reg. Section 1.1502-32(f)(2) nor a consent 
dividend election under Section 565 of the Code.  EyeSys has not agreed to 
make, nor is it required to make, any adjustment under Sections 481(a) or 
263A of the Code or any comparable provision of any applicable state or 
foreign tax laws by reason of a change in accounting method or otherwise.  
EyeSys has not participated in (and has not agreed to participate in) an 
international boycott within the meaning of Section 999 of the Code.  

                (h)  EyeSys is not a party to any agreement, contract, 
arrangement or plan that has resulted or would result, whether separately or 
in the aggregate, in connection with the Merger, or with any change of 
control of EyeSys or any other transaction contemplated by this Agreement, in 
the payment of any "excess parachute payments" within the meaning of Section 
28OG of the Code.  To the best knowledge of EyeSys, except as set forth in 
the EyeSys Letter, no Shareholder of EyeSys is other than a United States 
person within the meaning of the Code.  EyeSys does not have and has not had 
a permanent establishment in any foreign country, as defined in any 
applicable Tax treaty or convention between the United States of America and 
such foreign country, and EyeSys has not engaged in a trade or business 
within any foreign country.

                (i)  Except as set forth in the EyeSys Letter, EyeSys is not 
party to any joint venture, partnership, or other arrangement or contract 
which is treated as a partnership for federal income tax purposes.

                (j)  The unpaid Taxes of EyeSys do not exceed any reserve for 
Tax liability (excluding any reserve for deferred Taxes established to 
reflect timing differences between book and Tax income) set forth or included 
in EyeSys' balance sheets as at December 31, 1995 and September 30, 1996, as 
adjusted for the passage of time through the Effective Time in good faith in 
accordance with the past custom and practice of EyeSys.  No Tax liability of 
EyeSys has been incurred since December 31, 1995, other than in the ordinary 
course of business, and an adequate reserve on the Financials has been made 
for all Taxes since that date.

                (k)  After the date of this Agreement, no material election 
with respect to Taxes shall be made by EyeSys without the prior written 
consent of Premier and PAI.

                (l)  The liabilities of EyeSys to which the transferred 
assets of EyeSys are subject were incurred by EyeSys in the ordinary course 
of its business.

                (m)  To the best knowledge of EyeSys, there is no plan or 
intention on the part of the shareholders of EyeSys to sell, exchange, or 
otherwise dispose of such number of the Merger Shares as would reduce the 
EyeSys shareholders' ownership of shares of Premier 


                                        -31-



Common Stock to a number of shares having a value, determined as of the 
Effective Time, of less than 50% of the value, determined as of the Effective 
Time, of all of the shares of EyeSys Common and Preferred Stock outstanding 
immediately prior to the Effective Time. For purposes of this representation, 
shares of EyeSys Common or Preferred Stock exchanged for cash or other 
property surrendered by dissenters, shall be treated as outstanding EyeSys 
Common or Preferred Stock at the Effective Time of the Merger.  Moreover, 
shares of EyeSys Common or Preferred Stock and shares of Premier Common Stock 
held by EyeSys shareholders as of the date hereof and otherwise sold, 
redeemed, or disposed of prior or subsequent to the Merger will be considered 
in making this representation.

               (n)  EyeSys is not an investment company as defined in Section 
368(a)(2)(F)(iii) and (iv) of the Code.

               (o)  At least ninety percent (90%) of the fair market value of 
the net assets and at least seventy percent (70%) of the fair market value of 
the gross assets held by EyeSys immediately prior to the Merger will be held 
by the surviving corporation immediately after the Merger.  For the purpose 
of determining the percentage of EyeSys' net and gross assets held by the 
surviving corporation immediately following the Merger, the following assets 
will be treated as property held by EyeSys immediately prior to the Merger 
that is not held by the surviving corporation subsequent to the Merger:  (i) 
assets disposed of by EyeSys prior to the Merger and in contemplation thereof 
(including, without limitation, any asset disposed of by EyeSys, other than 
in the ordinary course of business, pursuant to a plan or intent existing 
during the period ending on the Effective Time of the Merger and beginning 
with the commencement of negotiations (whether formal or informal) with 
Premier regarding the Merger); (ii) assets disposed of after the Merger 
pursuant to a binding obligation entered into by EyeSys before the Merger and 
in contemplation thereof, other than in the ordinary course of business; 
(iii) assets used by EyeSys to pay shareholders perfecting dissenters' rights 
or other expenses or liabilities incurred in connection with the Merger; and 
(iv) assets used to make distribution, redemption or other payments in 
respect of EyeSys capital stock or rights to acquire such stock (including 
payments treated as such for tax purposes) that are made in contemplation of 
the Merger or related thereto.

               (p)  EyeSys has not sold, exchanged or discontinued any line 
or lines of business with a value representing in the aggregate more than 25% 
of the current fair market value of the total assets of EyeSys as of the 
Closing.

          3.21 OTHER TAXES.

               (a)  The hours worked by and payments made to EyeSys' 
employees have not been in violation of the Fair Labor Standards Act or any 
other applicable federal, foreign, state or local labor laws.

               (b)  All payments due from EyeSys on account of employee 
health and welfare insurance have been paid or accrued as a liability on its 
balance sheets included in the EyeSys Financials.


                                        -32-



               (c)  All severance and vacation payments which are or were due 
and payable by EyeSys under the terms of any agreement have been paid or 
accrued as a liability on its balance sheets included in the EyeSys 
Financials.

          3.22 COMPLIANCE WITH INSTRUMENTS.  EyeSys is not in violation of or
conflict with, breach of or in default under (either with the giving of notice
or the passage of time or both) any term or provision of the EyeSys Certificate
of Incorporation or its Bylaws.

          3.23 FOREIGN STATUS.  EyeSys is not a foreign corporation, foreign
partnership, foreign trust or foreign establishment (as each such term is
defined in the Code).

          3.24 CONSENTS AND APPROVALS.  The EyeSys Letter lists all consents
and approvals required for the execution and delivery of this Agreement by
EyeSys and the consummation of the Merger by EyeSys, including those that are
necessary because of the transactions contemplated by this Agreement or those
which are necessary to avoid the loss of the rights to use EyeSys' Intellectual
Property or other rights.

          3.25 ACCOUNTS RECEIVABLE.  The EyeSys Letter lists all accounts
receivable, unbilled invoices and other debts due or recorded in the records of
EyeSys, as of April 7, 1997.  Notwithstanding any annotations in the EyeSys
Letter schedule of accounts receivable, at least 95% of the amount of all
accounts receivable, unbilled invoices and other debts due or recorded in the
records and books of account of EyeSys as being due to EyeSys as at the date of
this Agreement will be good, payable and collectible in full in the ordinary
course of business within ninety (90) days after the Closing (or one hundred
twenty (120) days, with respect to receivables, invoices and debts due from
foreign (non-U.S.) payors), net of applicable reserves as recorded on EyeSys'
books on the date hereof; no contest with respect to the amount or validity of
any amount is pending; and none of such accounts receivable or other debts is or
will at the Closing be subject to any counterclaim or set-off.  The values at
which accounts receivable are carried reflect the accounts receivable valuation
policy of EyeSys which is consistent with GAAP applied on a consistent basis.

          3.26 INVENTORY.  The inventories shown on the Financials as of
December 31, 1995 and September 30, 1996 or thereafter acquired by EyeSys,
consisted of items of a quantity and quality usable or salable in the ordinary
course of business.  The inventories are valued at the lower of cost or market
value, determined in accordance with generally accepted accounting principles
consistently applied and on a basis which is consistent with the past practices
of EyeSys.  Since December 31, 1996, EyeSys has continued to replenish
inventories in a normal and customary manner consistent with past practices. 
EyeSys has not received written or oral notice that it will experience in the
foreseeable future any difficulty in obtaining, in the desired quantity and
quality and at a reasonable price and upon reasonable terms and conditions, the
raw materials, supplies or component products required for the manufacture,
assembly or production of its products.  Except as disclosed in the EyeSys
Letter, EyeSys does not have any sole source suppliers and has been and is able
to acquire component parts from multiple sources on a timely basis.  The values
at which inventories are carried reflect the inventory valuation policy of
EyeSys which is consistent with its past practice and in accordance with GAAP
applied on a consistent basis.


                                        -33-



          3.27 NO UNDISCLOSED LIABILITIES.  Except as set forth in the EyeSys 
Letter, there is no outstanding claim, liability or obligation of any nature, 
whether absolute, accrued, contingent or otherwise, other than: (a) the 
liabilities and obligations that are fully reflected, accrued or reserved 
against on the Financials for which the reserves are appropriate and 
reasonable; (b) liabilities incurred in the ordinary course of business since 
the date of the Financials, (c) Transactional Costs, or (d) contractual 
liabilities or obligations not required to be disclosed in the Financials 
prepared in accordance with GAAP.

          3.28 RELATED PARTY TRANSACTIONS.  Except as set forth in the EyeSys
Letter, or otherwise reflected in the Capitalization Table included in the
EyeSys Letter, no employee, officer or director of EyeSys or member of his or
her immediate family is indebted to EyeSys, nor is EyeSys indebted (or committed
to make loans or extend or guarantee credit) to any of them.  Except as set
forth in the EyeSys Letter, to the best of EyeSys' knowledge, none of such
persons has any direct or indirect ownership interest in any firm or corporation
with which EyeSys is affiliated or with which EyeSys has a business
relationship, or any firm or corporation that competes with EyeSys, except that
the employees, officers or directors of EyeSys and members of their immediate
families may own stock in publicly traded companies that may compete with
EyeSys.  No member of the immediate family of any officer or director of EyeSys
is directly interested in any material contract with EyeSys.

          3.29 DISTRIBUTION.  All of EyeSys' international distributors for 
its products are identified in the EyeSys Letter.  EyeSys has entered into 
written distribution agreements with each of such distributors, copies of 
which have been delivered to Premier.  All of such agreements are in full 
force and effect. To EyeSys' knowledge, no such distributor intends or 
expects to materially reduce the volume of purchases of EyeSys' products from 
the amounts purchased during the fiscal year ended December 31, 1996.

When used in this Article 3, "KNOWLEDGE" means information actually known or
which should have been known by any one of the directors of EyeSys or any of the
following:  Youssef Wakil, Kenneth Carbonari, David Harley, Michel Ulsas, David
Liu or Henry Kuehn after inquiry by such persons of EyeSys personnel who report
to them.

                                    ARTICLE 4

                 REPRESENTATIONS AND WARRANTIES OF PREMIER AND PAI

          Except as set forth in Premier Letter, which disclosures shall be 
deemed representations and warranties hereunder, each of Premier and PAI 
represents and warrants to EyeSys as follows:

          4.1  ORGANIZATION AND STANDING.

                                        -34-



corporation in each jurisdiction in which the failure to so qualify could or 
would have a Material Adverse Effect.

               (b)  Prior to Closing, each of Premier and PAI shall have 
delivered or made available to EyeSys complete and accurate copies of its 
current Certificates of Incorporation and Bylaws, as the case may be.

          4.3  AUTHORITY, APPROVAL AND ENFORCEABILITY.

               (a)  Subject to obtaining any required approvals of their 
respective stockholders, each of Premier and PAI has full corporate power and 
authority to execute, deliver and perform its obligations under this 
Agreement, and all corporate action on their respective parts necessary for

               (b)  Subject to obtaining all necessary consents, the

upon the failure to give notice or the lapse of time, or both, result in any 
conflict with, breach or violation of or default, termination or forfeiture 
under) any terms or provisions of its current Articles of Incorporation or 
Bylaws, as the case may be, or any statute, rule, regulation, judicial, 
governmental, regulatory or administrative decree, order or judgment, or any

               (c)  No consent, approval, authorization, order, registration, 
qualification or filing of or with any court or any regulatory authority or 
any other governmental or administrative body is required on its part for the

transactions contemplated by this Agreement, except the filing of the First

Certificate of Merger in the offices of the Secretaries of State of the 
States of Delaware and California.

               (d)  Subject to Premier, PAI and EyeSys obtaining the

insolvency, reorganization, moratorium or similar laws affecting creditors'
rights generally and subject to the availability of equitable remedies.

          4.4  FINANCIAL STATEMENTS.

               (a)  Premier has delivered or made available to EyeSys 
complete copies of its consolidated balance sheets as at March 31 for the 
fiscal years 1994 through 1996 and the 


                                        -35-



related statements of operations, shareholders' equity and cash flows for the 
years ended on each March 31 for the years 1994 through 1996 and the notes 
thereto (collectively, the "PREMIER AUDITED FINANCIALS") accompanied by the 
auditors' report and the opinion of its independent certified public 
accountants.  Premier's Audited Financials present fairly its consolidated 
financial position as of those dates and the results of its operations and 
cash flows for the years then ended, in conformity with GAAP applied on a 
consistent basis.

               (b)  Premier has delivered to EyeSys an unaudited consolidated 
balance sheet as of December 31, 1996 and the related unaudited statements of 
operations for the nine (9) months then ended (the "PREMIER INTERIM 
FINANCIALS").  Premier's Interim Financials present fairly its financial 
condition as of December 31, 1996 and the results of its operations and cash 
flows for the nine (9) months then ended, in conformity with GAAP applied on 
a basis consistent with the Premier Audited Financials (except for the 
absence of notes thereto and subject to normal year-end audit adjustments 
which are not material).  The Audited Financials and the Interim Financials 
are hereinafter collectively referred to as the "PREMIER FINANCIALS."

          4.5  MATERIAL CHANGES.  Since December 31, 1996, there has not been
any material change in Premier's assets, liabilities, financial condition or
operating results from that reflected in the Premier Financials or the
Registration Statement, except changes in the ordinary course of business that
have not been, in the aggregate, material.

          4.6  ABSENCE OF LITIGATION.  Neither Premier nor, to the best of its
knowledge, any of its officers or directors is engaged in, or has been
threatened with, any litigation, arbitration, investigation or other proceeding
relating to it, its employee benefit plans, property, business, assets,
licenses, permits or goodwill, or against or affecting the Merger or the actions
taken or contemplated in connection therewith, nor, to the best of its
knowledge, is there any reasonable basis therefor.  There is no action, suit,
proceeding or investigation pending or threatened against Premier that questions
the validity of this Agreement or the right of Premier or PAI to enter into this
Agreement or to consummate the transactions contemplated hereby or thereby or
which might result in any Material Adverse Effect.  The foregoing includes,
without limitation, actions pending or threatened (or any reasonable basis
therefor known to Premier) involving the prior employment of any of its
employees, their use in connection with its business of any information or
techniques allegedly proprietary to any of their former employers, or their
obligations under any agreements with prior employers.  There is no action,
suit, proceeding or investigation by Premier currently pending or which it
intends to initiate.  Neither Premier nor, to the best of its knowledge, any of
its officers or directors is bound by any judgment, decree, injunction, ruling
or order of any court, governmental, regulatory or administrative department,
commission, agency or instrumentality, arbitrator or any other person which
would or could have a Material Adverse Effect.

          4.7  NO BROKERS.  Except with respect to the fees payable to Cowen
pursuant to Section 5.21, Premier is not obligated for the payment of fees or
expenses of any broker or finder in connection with the origin, negotiation or
execution of this Agreement or in connection with any transaction contemplated
hereby.

          4.8  INSURANCE.  Premier maintains policies of insurance covering its
assets, properties and business in types and amounts customary for similarly
sized companies engaged 

                                        -36-



in similar businesses.  Premier is in compliance with each of such policies 
such that none of the coverage provided under such policies has been 
invalidated.  Premier has fully paid all premiums and other payments which 
may be due to its insurers.  The Premier Letter contains a complete and 
accurate list of all insurance policies, bonds and surety instruments.  There 
is no threat by any of the insurers to terminate or materially increase the 
premiums payable under any of such insurance policies due to the activities 
or loss experience of Premier.

          4.9  CAPITALIZATION.

               (a)  Premier's capitalization (common stock, preferred stock, 
warrants and options and any other issued or granted security) is as set 
forth in the Premier Letter.  Premier does not have in effect any stock 
appreciation rights plan and no stock appreciation rights are currently 
outstanding.

               (b)  Other than as set forth in the Premier Letter, Premier 
does not have outstanding any preemptive or subscription rights, options, 
warrants, rights to convert, capital stock equivalents or other rights to 
purchase or otherwise acquire any of Premier's capital stock or other 
securities.

               (c)  All of the issued and outstanding shares of Premier's 
capital stock have been duly authorized, validly issued, are fully paid and 
nonassessable, and such capital stock has been issued in full compliance with 
all applicable federal and state securities laws.  All of Premier's incentive 
stock options have been issued in compliance with all laws, rules and 
regulations necessary to preserve such incentive stock option treatment.  All 
of Premier's options have been issued in accordance with Premier's current 
stock option plans.  None of Premier's options are entitled to be accelerated 
as a result of the Merger.

               (d)  Except for any restrictions imposed by applicable state 
and federal securities laws, there is no right of first refusal, co-sale 
right, right of participation, right of first offer, or other restriction on 
transfer applicable to any shares of Premier capital stock.

               (e)  Except as described in the Premier Letter, Premier is not 
and will not be under any obligation to register under the Securities Act any 
shares of its capital stock or any other of its securities that might be 
issued in the future if the Merger were not consummated.

               (f)  Premier is not a party or subject to any agreement or 
understanding, and, to Premier's knowledge, there is no agreement or 
understanding between or among any persons that affects or relates to the 
voting or giving of written consent with respect to any security.

          4.10 COMPLIANCE WITH LAWS.  The business and operations of Premier
and PAI are in compliance with all foreign, federal, state, local and county
laws, ordinances, regulations, judgments, orders, decrees or rules of any court,
arbitrator or governmental, regulatory or administrative agency or entity,
except where the failure so to comply would not have a Material Adverse Effect. 
Each of Premier and Premier PAI has all valid and current permits, licenses,
orders, authorizations, registrations, approvals and other analogous instruments
(and each is in 

                                        -37-



full force and effect) and each of Premier and PAI has made all filings and 
registrations and the like necessary or required by law to conduct its 
business as presently conducted, except where the failure to maintain such 
permits and other instruments or to make such filings and registrations would 
not have a Material Adverse Effect.  Neither Premier nor PAI has received any 
governmental notice within two years of the date hereof of any violation by 
it of any such laws, rules, regulation or orders.  Neither Premier nor PAI is 
in material default or material noncompliance under any such permits, 
consents, or similar instruments.

          4.11 THE REGISTRATION STATEMENT AND PROXY STATEMENT/PROSPECTUS.  The
Registration Statement pursuant to which the Premier Common Stock to be issued
in the Merger will be registered with the SEC shall not, at the time the
Registration Statement is declared effective by the SEC, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading.  The
information supplied by Premier and PAI for inclusion in the Proxy
Statement/Prospectus to be sent to the holders of Interests in EyeSys will not,
on the date the Proxy Statement/Prospectus (or any amendment thereof or
supplement thereto) is first mailed to holders of Interests in EyeSys, at the
time of the EyeSys Stockholder Meeting or at the Effective Time, contain any
statement which, at such time and in light of the circumstances under which it
shall be made, is false or misleading with respect to any material fact, or
shall omit to state any material fact necessary in order to make the statement
made therein not false or misleading.  If at any time prior to the Effective
Time any event relating to Premier or PAI or any of their respective affiliates,
officers or directors should be discovered by Premier or PAI which should be set
forth in an amendment to the Registration Statement or a supplement to the Proxy
Statement/Prospectus, Premier and PAI shall promptly inform EyeSys.  The Proxy
Statement/Prospectus, including all financial statements of Premier and PAI
required to be included therein, shall comply in all material respects as to
form with the requirements of the Securities Act, the Exchange Act and the rules
and regulations thereunder.  Notwithstanding the foregoing, Premier and PAI make
no representation or warranty with respect to any information supplied by EyeSys
which is contained in any of the foregoing documents.

          4.12 TAXES.

               (a)  Prior to the Merger, Premier will be in control of PAI 
within the meaning of Section 368(c) of the Code.  Premier shall not cause or 
permit PAI to issue additional shares of its stock that would result in 
Premier losing control of PAI within the meaning of Section 368(c) of the 
Code.  No stock of PAI will be issued in the Merger.

               (b)  During its corporate existence, PAI has owned no assets, 
and prior to the Merger shall not own any assets other than the Merger Shares 
of Premier to be distributed in the Merger.

               (c)  As of the date hereof and as of the Effective Time, 
Premier has no plan or intention to reacquire any of its stock issued in the 
Merger, other than the possible acquisition of the Escrow Shares pursuant to 
Article 7 hereof.

                                        -38-



               (d)  Premier shall not: liquidate PAI; merge PAI with or into 
another corporation; sell or otherwise dispose of the stock of PAI in any 
transaction other than this Merger, nor cause PAI to sell or otherwise 
dispose of any of the assets of EyeSys acquired in the Merger, except for 
dispositions made in the ordinary course of business transfers described in 
Section 368(a) of the Code, or other liquidations, dispositions or transfers 
which may be made without disqualifying the Merger as a tax-free 
reorganization under the Code. Following the Merger, Premier will cause 
EyeSys to continue the historic business of EyeSys or to use a significant 
portion of EyeSys' business assets in a business.

               (e)  There is no intercorporate indebtedness existing between 
EyeSys and Premier nor between EyeSys and PAI that was issued, acquired, or 
will be settled at a discount.  Premier is not an investment company as 
defined in Section 368(a)(2)(F)(iii) and (iv) of the Code.

          4.13 SHARES FULLY PAID AND NON-ASSESSABLE.  The shares of Premier
Common Stock issuable to holders of Interests in EyeSys pursuant to Section 2.2,
when issued as contemplated by this Agreement, will be duly authorized, validly
issued, fully paid and nonassessable and free of any preemptive rights of any
security holder of Premier.

          4.14 SEC DOCUMENTS.  Premier has furnished, or within 10 days of the
date hereof shall furnish, EyeSys with a true and complete copy of each report,
schedule, registration statement and definitive proxy statement filed by Premier
with the SEC since November 1, 1994 (the "SEC DOCUMENTS"), which are all the
documents that Premier was required to file with the SEC under the Exchange Act
since that date.  The SEC Documents as of their respective dates complied in all
material respects with the requirements of the Exchange Act and the rules and
regulations of the SEC thereunder, applicable to such SEC Documents, and none of
the SEC Documents as of the date thereof contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading.  Except to the
extent that the information contained in Premier's Annual Report on Form 10-K
for its fiscal year ended March 31, 1996 ("FORM 10-K") has been revised or
superseded by a later-filed SEC Document, or except as set forth in the
Registration Statement or the Premier Letter, the Form 10-K does not currently
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.  The financial statements of Premier included in the SEC Documents
as of their respective dates complied as to form in all material respects with
applicable accounting requirements and the rules and regulations of the SEC with
respect thereto and have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods involved,
except as may be indicated in the notes thereto or, in the case of unaudited
statements, as permitted by Form 10-Q and subject to normally recurring audit
adjustments.

                                        -39-


                                 ARTICLE 5

                     COVENANTS OF PREMIER, PAI AND EYESYS

          Each of Premier, PAI and EyeSys, as the case may be, covenants to the
other, except as expressly provided otherwise herein, as follows:

          5.1  MAINTENANCE OF BUSINESS.

               (a)  During the period from the date hereof to the Effective 
Time, it shall carry on and preserve its business, goodwill and its 
relationships with distributors, customers, suppliers, officers, employees, 
agents and others in substantially the same manner as it did prior to the 
date of this Agreement.  It will use its reasonable efforts to keep and 
maintain the existing favorable business relationship with each of such 
distributors, customers, suppliers, officers, employees and agents.  If it 
becomes aware of a deterioration in a relationship with any distributor, 
customer, supplier, officer, employee or agent which is material to its 
business or prospects, it will promptly bring such information to the 
attention of the other and will use its best efforts to restore such 
relationship or establish a reasonable replacement relationship, as may be 
appropriate.  EyeSys recognizes that Premier and PAI intend to continue 
certain of EyeSys' existing businesses after the Effective Date and that 
Premier and PAI intend to continue EyeSys' current relationships with its 
customers and other parties.

               (b)  EyeSys agrees to consult with Premier concerning any 
material operating decisions (including, without limitation, proposed 
employee hiring layoff and termination decisions).  Notwithstanding the 
foregoing, EyeSys expressly acknowledges that EyeSys alone shall make such 
operating decisions and shall be solely responsible for their implementation, 
consequences and liabilities, if any.

          5.2  ABSENCE OF CERTAIN CHANGES.  Prior to the Closing, except as 
expressly permitted or contemplated hereby, or except as set forth in the 
EyeSys Letter or the Premier Letter, as the case may be, neither party shall, 
without the prior written consent of the other party:

               (a)  incur any additional indebtedness for money borrowed or 
guarantee any indebtedness or obligation of any other party; set aside or pay 
any dividend or distribution of assets to, or repurchase any of its stock 
from any of its shareholders; issue or grant any securities or securities 
convertible into capital stock or grant or issue any options, warrants or 
rights to subscribe for its capital stock or securities convertible into its 
capital stock;

               (b)  enter into, amend or terminate any employment or 
consulting agreement or any similar agreement or arrangement; increase the 
compensation payable or to become payable to any of its officers, employees 
or agents above the amount payable as of December 31, 1996, or adopt or amend 
any employee benefit plan or arrangement;

               (c)  acquire or dispose of any properties or assets used in 
its business except in the ordinary course of business; permit any change in 
the nature of business or the manner in which its books and records are 
maintained;

                                    -40-



               (d)  waive any statute of limitations so as to extend any tax 
or other liability; create or suffer to be imposed any lien, mortgage, 
security interest or other charge on or against its properties or assets; or 
enter into, amend or terminate any lease of real or personal property 
otherwise than in the ordinary course of business;

               (e)  except as contemplated by Section 2.1, amend its 
Certificate of Incorporation or Bylaws; engage in any activities or 
transactions outside the ordinary course of its business as conducted at the 
date hereof; make any amendments or changes in any instruments, agreements, 
other documents or written information delivered by it or its representatives 
to the other or its representatives; or accelerate the vesting of any 
employee stock benefit (including vesting under stock purchase agreements or 
the exercisability of stock options).

          5.3  ACTIONS CONTRARY TO STATED INTENT.  Each party will use its 
best efforts to cause the Merger to qualify as a tax-free reorganization 
under Section 368(a) of the Code and accordingly will not, either before or 
after consummation of the Merger, take any action or fail to take any action 
that would prevent the Merger from so qualifying as a tax-free reorganization 
under Section 368(a) of the Code, or that would be inconsistent with such 
qualification.

          5.4  ACCESS TO INFORMATION.  Each party will give to the other 
party and their respective accountants, legal counsel and other 
representatives full access, during normal business hours throughout the 
period prior to the Closing, to all of the properties, books, contracts, 
commitments and records relating to its business, assets and liabilities, and 
each party will furnish to the other party, their respective accountants, 
legal counsel and other representatives during such period all such 
information concerning its affairs as the other may reasonably request but 
subject to Section 9.10 below; provided, that any furnishing of such 
information pursuant hereto or any investigation by each party hereto shall 
not affect such party's right to rely on the representations, warranties, 
agreements and covenants made by the other party in this Agreement.

          5.5  OTHER DISCUSSIONS.  From the date hereof until the Closing or 
the termination of this Agreement in accordance with Article 8 hereof, 
whichever occurs first, neither EyeSys nor any officer, director, 
shareholder, agent or representative of EyeSys will discuss or negotiate, or 
authorize any person or entity to discuss or negotiate on its or their 
behalf, with any other party, concerning the possible disposition of EyeSys' 
business, assets or capital stock, except that such persons may discuss and 
negotiate back-up offers to sell or otherwise dispose of EyeSys' business, 
assets or capital stock in case the Merger is not consummated pursuant to 
this Agreement, provided that EyeSys must inform any potential purchaser or 
acquirer that EyeSys has entered into this definitive Agreement with Premier.

          5.6  EYESYS LOCK-UP AGREEMENTS.  EyeSys shall use its reasonable 
best efforts to cause the EyeSys Shareholders to execute and deliver to 
Premier the EyeSys Lock-Up Agreements.

          5.7  REASONABLE BEST EFFORTS.  Each party will use its reasonable 
best efforts to cause all conditions to the Closing to be satisfied, 
including obtaining any of its consents 

                                    -41-



necessary or desirable in connection with the consummation of the 
transactions contemplated by this Agreement.

          5.8  REGISTRATION STATEMENT AND PROXY STATEMENT/PROSPECTUS.  As 
promptly as practicable, Premier, PAI and EyeSys shall prepare and file with 
the SEC preliminary proxy materials which shall constitute the Proxy 
Statement/Prospectus and the Registration Statement of Premier with respect 
to the Premier Common Stock to be issued in connection with the Merger and 
shall use all reasonable efforts to cause the Registration Statement to 
become effective as soon as practicable, and to mail the Proxy 
Statement/Prospectus to EyeSys shareholders, as soon thereafter as 
practicable.  The Proxy Statement/Prospectus shall include the recommendation 
of the Boards of Directors of Premier and EyeSys in favor of the Merger; 
provided, that the Boards of Directors of Premier or EyeSys may, at any time 
prior to the Effective Time, withdraw, modify or change such recommendation 
if, in the opinion of either such Board of Directors, the Board determines in 
good faith that there is a reasonable possibility that the failure to 
withdraw, modify or change such recommendation could be a breach of its 
fiduciary duties under applicable law. EyeSys shall call and hold a 
shareholder meeting as promptly as practicable after the date on which the 
Registration Statement becomes effective and in accordance with applicable 
laws for the purpose of obtaining the approvals required herein.

          5.9  EYESYS PAYABLES.  EyeSys shall pay its accounts payable, 
including (without limitation) its payroll, amounts due under equipment and 
facilities leases, loan agreements and similar leases and agreements, sales 
and payroll taxes and trade payables, and all other taxes, in a timely manner.

          5.10 TAX FORMS.  EyeSys shall not make or change any material Tax 
election, adopt or change any material Return or any amendment to a material 
Return, enter into any closing agreement, settle any Tax claim or assessment, 
file any state or federal income tax return, or consent to any extension or 
waiver of limitation period applicable to any Tax claim or assessment, 
without the prior consent of Premier, which consent will not be unreasonably 
withheld.

          5.11 NOTIFICATION OF CERTAIN MATTERS.  EyeSys shall give prompt 
notice to Premier, and Premier and PAI shall give prompt notice to EyeSys, of 
(a) the occurrence or nonoccurrence of any event the occurrence or 
nonoccurrence of which would be likely to cause any representation or 
warranty of the notifying party contained in this Agreement to become 
materially untrue or inaccurate, or (b) any failure of the notifying party to 
materially comply with or to satisfy any covenant, condition or agreement to 
be complied with or satisfied by it hereunder.

          5.12 MERGER EXPENSES.  EyeSys will use its best efforts to limit 
all of its non merger-related fees and expenses to be incurred by it prior to 
or on the Closing.


          5.13 ASSUMPTION OF BANK LOAN AGREEMENT.  EyeSys and the Silicon 
Valley Bank ("BANK") have entered into that certain Bank Loan Agreement, 
dated as of March 11, 1995, as amended, pursuant to which the Bank agreed to 
loan EyeSys up to $2,100,000 (the "LOAN AGREEMENT").  Up to $650,000 of such 
loan has been guaranteed by each of Frontenac VI Limited Partnership and 
American Healthcare Fund II, L.P., shareholders of EyeSys (the 

                                    -42-



"SHAREHOLDER GUARANTEES"). EyeSys shall use its reasonable best efforts to 
obtain the agreement of the Bank, or another lender acceptable to Premier, to 
agree to advance at least $2,100,000 for at least one year after Closing at 
advance rates no greater than those specified in the Loan Agreement, with 
such adjustments to the loan covenants as reflect the merged companies and 
are acceptable to Premier. Premier agrees to provide to Bank the corporate 
guaranty of Premier with respect to $300,000 principal amount of indebtedness 
of EyeSys to Bank; provided, however, that (i) Bank's recourse under such 
guaranty shall be limited to Premier's accounts receivable, inventory and 
fixed assets; (ii) Premier's obligation to provide such guaranty is subject 
to the condition that Frontenac Company and/or other shareholders reasonably 
acceptable to Premier shall have agreed that in the event the Merger is 
terminated for any reason, Frontenac and such other shareholders shall 
provide a guaranty to Bank in substitution for the guaranty provided by 
Premier; and (iii) Bank shall have agreed to accept such substitute guaranty 
in lieu of the Premier guaranty.

          5.14 PREMIER COVENANT REGARDING SEC FILINGS.  For the benefit of 
affiliates of EyeSys, Premier agrees to make all filings it is required to 
make pursuant to the Exchange Act through 1998 on a timely basis; provided, 
however, that Premier shall be entitled to cure any late filings in 
accordance with the Exchange Act and the rules and regulations promulgated 
thereunder.

          5.15 PREMIER BOARD SEAT.  Commencing with the next annual meeting 
of Premier shareholders at which directors are to be elected after the 
Closing (or at such earlier time as there may be a vacancy on Premier Board 
of Directors), Premier shall nominate for election to its Board of Directors 
a person who is designated from time to time by Frontenac Co., and who is 
reasonably acceptable to Premier.  The foregoing obligation shall terminate 
on the earlier of:  (i) three (3) years from the Closing Date of the Merger; 
or (ii) at such time as the persons receiving Premier Common Stock in the 
Merger hold in the aggregate less than five percent (5%) of the outstanding 
Premier voting stock.

          5.16 FUNDING FOR EYESYS.  From the date hereof until the earlier of 
the Closing or the termination of the Merger in accordance with Article 8 
below, Premier will loan to EyeSys, pursuant to a Demand Promissory Note 
bearing interest at the rate of 10.5% per annum (or, if less, the maximum 
rate permitted by law) and secured by substantially all of the assets of 
EyeSys, the Reasonable Cash Requirements of EyeSys; provided that Premier's 
obligation to provide such loan shall be subject to the conditions that:  (i) 
all necessary approvals of shareholders of EyeSys with respect to the Merger 
and the transactions contemplated hereby shall have been obtained and shall 
be irrevocable (provided that for this purpose, the delivery of irrevocable 
written consents to the Merger by those EyeSys shareholders holding 
sufficient votes to approve the Merger under its charter documents and 
applicable law shall be deemed to satisfy this condition); (ii) EyeSys shall 
not be in breach of any material representation, warranty or covenant set 
forth in this Agreement; (iii) no regulatory approvals or licenses shall be 
required as a condition to the Closing (other than approval of the Securities 
and Exchange Commission of the Registration Statement); (iv) the condition 
set forth in Section 6.17 concerning the Bank's credit facilities shall have 
been met, and (v) the employees of EyeSys identified on Schedule 5.16 shall 
have agreed to be employed by Premier after the Closing.  For purposes 
hereof, the term "REASONABLE CASH REQUIREMENTS" shall mean the monthly cash 
requirements of EyeSys following the execution of this Agreement as set forth 
in that certain 

                                    -43-



operating plan of EyeSys attached hereto as Exhibit G (the "OPERATING PLAN"), 
but in no event shall exceed $100,000 per month.

          5.17 NONINCLUDED COSTS.  EyeSys shall make arrangements for the 
payment of the Nonincluded Costs either out of the Merger Shares or from the 
proceeds received by EyeSys after the date hereof from the exercise of any 
option or warrant, but in no event from the funds or other assets of EyeSys.

          5.18 OPTIONS AND WARRANTS.  Prior to the Closing, EyeSys shall make 
arrangements for the exercise, termination or exchange of the EyeSys Options 
and EyeSys Warrants, as set forth herein.  Any cash proceeds received as a 
result of such exercise may be applied by EyeSys to the payment of the 
Nonincluded Costs.

          5.19 MARCH 31, 1997 FINANCIAL STATEMENTS.  Prior to the Closing, 
EyeSys shall prepare and forward to Premier unaudited financial statements 
for the three-month period ended March 31, 1997, which statements shall be 
prepared in accordance with GAAP, and shall be subject to normal audit 
adjustments, but shall reflect accounting policies and conventions with 
respect to reserves, write-offs and other similar matters approved by 
Premier.  Prior to the Closing, Premier shall prepare and forward to EyeSys 
unaudited financial statements for the year ended March 31, 1997, which shall 
be prepared in accordance with GAAP but shall be subject to normal audit 
adjustments, and shall further deliver, upon completion, copies of its 
audited financial statements for such fiscal year (provided that EyeSys shall 
maintain such financial statements as confidential until such time as a press 
release or other public announcement concerning Premier's results of 
operations for such fiscal year has been published).

          5.20 "STAY BONUSES," RSS PAYABLE.  Prior to the Closing, EyeSys 
shall make arrangements for the termination and/or satisfaction of all 
bonuses or other consideration payable to EyeSys employees, consultants or 
advisers in order to induce them to remain in the employ of, or to continue 
to render services to, EyeSys  (the "Stay Bonuses").  Prior the Closing, 
EyeSys shall also make arrangements for the compromise and payment of all 
amounts due by EyeSys to RSS, LLC.  Any amounts payable in connection with 
the foregoing arrangements shall be paid from the Merger Shares or the 
proceeds thereof.

          5.21 TRANSACTIONAL COSTS.  EyeSys shall deliver to Premier at least 
two business days prior to the Closing a list of the transactional fees 
claimed by the parties listed on Schedule 5.21 in connection with the Merger. 
 At the Effective Time, Premier shall pay the lesser of: (i) the 
Transactional Costs of such parties, or (ii) the amount of $100,000, to be 
applied to the Transactional Costs other than the fees payable to Cowen.  In 
addition, Premier shall pay a cash payment to Cowen of the lesser of 
(i) $75,000 or (ii) one-fourth of the investment banking fee of Cowen (the 
"COWEN FEES"), and shall issue the Cowen Shares to Cowen, all of which shall 
be in payment of one-half of the investment fee due Cowen.  EyeSys shall be 
responsible for paying the remaining portion of such transactional costs and 
remaining portion of the Cowen Fee, pursuant to Section 5.17 hereof.   At the 
Effective Time, Premier also shall repay on behalf of EyeSys the amount of 
$72,500 in full satisfaction of the Frontenac Payable.

                                    -44-



          5.22 REIMBURSEMENT OF AMOUNTS PAID TO DISSENTING SHAREHOLDERS.  The 
Principal Shareholder agrees that if the total amount payable to Dissenting 
Shareholders under the Delaware General Corporation Law ("APPRAISAL RIGHTS"), 
as a result of the exercise of their Appraisal Rights, exceeds $250,000, the 
Principal Shareholder shall sell Premier Common Stock received by it in the 
Merger, in a manner reasonably acceptable to Premier, until the net proceeds 
from such sale(s) equals the total amount payable to such Dissenting 
Shareholders, and shall remit such net proceeds to Premier to reimburse it 
for the amounts so paid to Dissenting Shareholders.  The Principal 
Shareholder shall be released from its Lock Up Agreements to the extent 
necessary to sell Premier Common Stock under this Section 5.22.  The maximum 
number of shares that the Principal Shareholder shall sell hereunder is equal 
to the number of Escrowed Dissenting Shares.

                                          INDEMNITY

          7.1  INDEMNIFICATION.  EyeSys agrees to indemnify, defend and hold 
harmless Premier and PAI from and against and shall reimburse Premier and PAI 
against and in respect of any and all claims, demands, losses, costs, 
expenses, obligations, liabilities, damages, remedies and penalties, 
including interest, penalties and reasonable attorneys' fees and expenses 
(collectively, "LOSSES") that Premier or PAI shall incur or suffer and which 
arise from or are attributable to by reason of or in connection with any 
breach or inaccuracy of or any failure to perform or comply with any of 
EyeSys' representations, warranties, agreements or covenants contained in 
this Agreement (including any exhibit, letter, schedule or certificate 
referred to herein) or in the Escrow Agreement.  Notwithstanding the 
foregoing, in the absence of fraud, EyeSys shall have no obligations under 
this Section 7.1 with respect to Losses that would otherwise be deemed to 
have incurred:  (a) due to a breach of a representation or warranty by EyeSys 
with respect to its inventory, or (b) as a result of the condition of its 
fixed assets, so 

                                    -48-



long as the representations and warranties set forth in the first two 
sentences of Section 3.8(a) hereof are true and correct.

          7.2  ESCROW AGREEMENT.  The indemnity obligations of EyeSys 
hereunder shall be met pursuant to the terms and conditions of the Escrow 
Agreement.  The indemnification made pursuant to Section 7.1 and the 
representations, warranties, covenants and other agreements set forth in this 
Agreement and in the Escrow Agreement, shall survive Closing for a period of 
twelve (12) months after the Effective Time, except that indemnity for Losses 
for which claim has been made pursuant to the terms of the Escrow Agreement 
against the Escrow Shares within such twelve (12)-month period shall survive 
until resolved pursuant to the terms of the Escrow Agreement.  As set forth 
herein, the indemnity obligations of EyeSys under this Article 7 (together 
with all of EyeSys' representations, warranties, covenants and other 
agreements) set forth herein shall survive the Closing and, absent fraud, 
shall be satisfied solely and exclusively by recourse against the Escrow 
Shares in accordance with the Escrow Agreement and this Agreement.

          7.3  NO WAIVER.  No investigation made by or on behalf of Premier 
or PAI with respect to EyeSys shall be deemed to affect Premier's or PAI's 
reliance on the representations, warranties, covenants and agreements made by 
EyeSys contained in this Agreement and shall not be a waiver of Premier's or 
PAI's rights to indemnity as herein provided for the breach or inaccuracy of 
or failure to perform or comply with any of EyeSys' representations, 
warranties, covenants or agreements under this Agreement or the Escrow 
Agreement.

          7.4  INDEMNIFICATION OF EYESYS AGENTS.  Premier agrees that until 
six (6) years from the Effective Time, Premier shall maintain all rights to 
indemnification existing in favor of the present and former directors, 
officers, employees, fiduciaries and agents of EyeSys under the terms of its 
charter and bylaws in effect immediately prior to the Effective Time, and 
that the charter and bylaws of EyeSys as the surviving corporation, or any 
successor in interest of EyeSys, shall not be amended to reduce or limit the 
rights of indemnity afforded to such persons.

          7.5  INDEMNIFICATION REGARDING SECURITIES ACT ISSUES.  In connection
with the registration by Premier of any of its securities under the Securities
Act pursuant to this Agreement, EyeSys shall indemnify and hold harmless
Premier, each underwriter (as defined in the Securities Act) and each
controlling person of any holder or underwriter, if any (within the meaning of
the Securities Act), against any losses, claims, damages of liabilities, joint
or several (or actions in respect thereof), to which Premier, such underwriter
or controlling person may be subject under the Securities Act, under any other
statute or at common law, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon (i) any untrue
statement (or alleged untrue statement) of any material fact contained in any
registration statement under which such securities were registered under the
Securities Act, any preliminary proxy statement/prospectus or final proxy
statement/prospectus contained therein, or any amendment to supplement thereto,
or any other document, or (ii) any omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or (iii) any violation by EyeSys of the Securities Act or any Blue
Sky law, or any rule or regulation promulgated under the Securities Act or any
Blue Sky law, or any other 

                                    -49-



law, applicable to Premier in connection with any such registration, 
qualification or compliance, and shall reimburse each such holder, 
underwriter or controlling person for any legal or other expenses reasonably 
incurred by such holder, underwriter or controlling person in connection with 
investigating or defending any such loss, claim, damage, liability or action; 
provided, however, that EyeSys shall not be liable to Premier, any 
underwriter or any controlling person in any such case unless and to the 
extent that any such loss, claim, damage or liability arises out of or is 
based upon any such untrue statement or omission made in such registration 
statement, preliminary prospectus, summary prospectus, prospectus, or 
amendment or supplement thereto, or any other document, in reliance upon and 
in conformity with written information furnished to Premier by EyeSys 
specifically for use therein.  The indemnity provided for herein shall remain 
in full force and effect regardless of any investigation made by or on behalf 
of Premier or such underwriter or controlling person.

          2.   INDEMNIFICATION.  Pursuant to Article 7 of the Merger Agreement,
EyeSys has entered into the following indemnification agreement:

     "EyeSys agrees to indemnify, defend and hold harmless Premier and PAI
     from and against and shall reimburse Premier and PAI against and in
     respect of any and all claims, demands, losses, costs, expenses,
     obligations, liabilities, damages, 

                                    -2-



     remedies and penalties, including interest, penalties and reasonable 
     attorneys' fees and expenses (collectively, "LOSSES") that Premier or 
     PAI shall incur or suffer and which arise from or are attributable 
     to by reason of or in connection with any breach or inaccuracy of or 
     any failure to perform or comply with any of EyeSys' representations,
     warranties, agreements or covenants contained in this Agreement 
     (including any exhibit, letter, schedule or certificate referred to 
     herein) or in the Escrow Agreement.  Notwithstanding the foregoing, 
     in the absence of fraud, EyeSys shall have no obligations under this 
     Section 7.1 with respect to Losses that would otherwise be deemed to 
     have incurred:  (a) due to a breach of a representation or warranty 
     by EyeSys with respect to its inventory, or (b) as a result of the 
     condition of its fixed assets, so long as the representations and 
     warranties set forth in the first two sentences of Section 3.8(a) 
     hereof are true and correct."
     
     EyeSys has also agreed in the Agreement that in the circumstances set 
forth in Section 2.2(c)(vi) of the Agreement, it may be required to return 
certain Escrow Shares to Premier.  Any claim by Premier that it is entitled 
to the receipt of such securities under Section 2.2(c)(vi) shall be deemed a 
"claim for indemnification" hereunder, and the amount of Escrow Shares 
Premier believes it is entitled to as a result thereof shall be treated as a 
"LOSS" hereunder. 

          3.   ESCROW HOLDER.  Pursuant to Section 1.3 of the Merger 
Agreement, as of the Effective Time, Premier shall cause the Escrow Shares to 
be deposited with Escrow Holder.  Escrow Holder shall hold, safeguard, and 
distribute the Escrow Shares in accordance with the terms and instructions 
set forth in this Agreement.

          4.   ESCROW PERIOD.  The Escrow Shares shall be held in escrow by 
the Escrow Holder for a period of twelve (12) months after the Effective 
Time, except that if any notice of a claim for indemnification has been given 
to Escrow Holder by Premier against the Escrow Shares within such twelve 
(12)-month period, such number of Escrow Shares as may be necessary to 
satisfy the claim for indemnification (as determined pursuant to Section 10 
below) shall remain in escrow until such time as all of such indemnification 
claims have been resolved pursuant to Section 8 or Section 9 of this 
Agreement (the "ESCROW PERIOD").

          5.   THE EYESYS REPRESENTATIVE.  The EyeSys Representative shall 
act as the agent of EyeSys and the Escrow Shareholders, for the purpose of 
receiving all notices, giving all approvals, and doing all other things and 
exercising all other rights of EyeSys and the Escrow Shareholders pursuant to 
this Agreement. The EyeSys Representative has agreed to waive the right to 
any fees for performing such services.  Any costs or expenses incurred by the 
EyeSys Representative in performance of his obligations under this Agreement 
shall be reimbursed from the Escrow Shares at the expiration of the Escrow 
Period, subject to the prior satisfaction of any rights of Premier to 
reimbursement from the Escrow Shares.

          6.   PREMIER CERTIFICATION.  In the event that Premier believes in 
good faith that it is entitled to indemnification pursuant to the Merger 
Agreement, or to receive Escrow Shares under Section 2.2(c)(vi) of the Merger 
Agreement, Premier shall deliver a notice (the "PREMIER NOTICE") to the 
Escrow Holder and the EyeSys Representative which:

                                    -3-



               (a)  states that Premier anticipates that it may sustain 
Losses for which it is entitled to indemnification pursuant to the Merger 
Agreement; and the nature of the misrepresentation, breach of warranty or 
covenant, or other basis upon which the claim for indemnification is based; 
and

               (b)  provides a good faith estimate of the amount of Losses 
which Premier may sustain, if Premier has sufficient information upon which 
to estimate reasonably the amount of the Losses, including any amounts paid 
or accrued as of the date of the Premier Certificate, if applicable.

At such time as Premier has determined the exact amount of any claim for 
Losses, Premier shall deliver a certificate signed by the chief executive 
officer, president or any vice president of Premier to Escrow Holder and the 
EyeSys Representative ("PREMIER CERTIFICATE") which certifies that Premier is 
entitled to payment of the amount specified pursuant to this Merger Agreement 
and this Agreement.

          7.   DISTRIBUTIONS TO PREMIER OF THE ESCROW SHARES.  Subject to the 
provisions of Section 8 of this Agreement, within no more than forty-five 
(45) days after receipt of a Premier Certificate which makes claim for a 
specific amount, Escrow Holder shall distribute to Premier such number of the 
Escrow Shares, based upon the Share Price, as is equal to the amount claimed 
by Premier in the Premier Certificate.  To the extent that the Escrow Shares 
consist of different types of securities (e.g., Common Stock or different 
types of options), Premier shall be entitled to specify which types of such 
securities are to be distributed to it under this Section 7.

          8.   OBJECTIONS TO DISTRIBUTIONS.  Notwithstanding Section 7 of 
this Agreement, Escrow Holder shall not make any distribution of Escrow 
Shares claimed by Premier unless Escrow Holder either (a) has received 
written authorization from the EyeSys Representative to make the 
distribution, or (b) at least thirty (30) days have elapsed from the date 
that Escrow Holder determines that a Premier Certificate was delivered to the 
EyeSys Representative without any response from the EyeSys Representative.  
Escrow Holder shall distribute such number of Escrow Shares to Premier as is 
required pursuant to Section 7 no later than five (5) days after receipt of 
authorization from the EyeSys Representative or expiration of the thirty 
(30)-day period.  If the EyeSys Representative has a reasonable basis for 
objecting to a claim for Losses from Premier and has provided the Escrow 
Holder with written notice of an objection ("NOTICE OF OBJECTION") within 
such thirty (30)-day period, Escrow Holder shall make a distribution of the 
Escrow Shares only when permitted pursuant to Section 9 of this Agreement.

          9.   SETTLEMENT OF DISPUTED CLAIMS; ARBITRATION.

               (a)  If the EyeSys Representative delivers a Notice of 
Objection to the reimbursement of Premier for any claim made in any Premier 
Certificate, the EyeSys Representative and Premier shall attempt in good 
faith to agree on the rights of the respective parties regarding any disputed 
claims.  At such time as the EyeSys Representative and Premier may reach 
agreement, a memorandum setting forth the agreement shall be prepared and 
signed by both parties and shall be furnished to Escrow Holder.  Escrow 
Holder shall be entitled to rely 

                                    -4-



on any such memorandum, and shall promptly make distributions of the Escrow 
Shares in accordance with the terms of such a memorandum.

               (b)  If no such agreement has been reached within fifteen (15) 
days after a Notice of Objection from the EyeSys Representative, such 
disputed claim may be sent to mediation in accordance with such mediation 
procedures as the parties may agree.  If the dispute has not been resolved 
within sixty (60) days after issuance of a Notice of Objection from the 
EyeSys Representative, the dispute shall be submitted to arbitration as set 
forth below.  The mediator of any dispute submitted to mediation under this 
section shall not serve as arbitrator of such dispute unless otherwise agreed 
to by all of the parties to the arbitration.  In addition to resolving 
pending disputes, the mediator shall provide assistance with respect to 
allocating responsibility for the costs of mediation.

               (c)  If, and to the extent that, any disputed claim is not 
resolved through good faith negotiation or through mediation in accordance 
with subsections (a) and (b) above, such disputed claim shall, upon demand of 
a party, be submitted to and decided by binding arbitration.  The arbitration 
shall be conducted pursuant to Part 3, Title 9 of the California CODE OF 
CIVIL PROCEDURE (Sections 1280-1288.8).  Discovery, including depositions for 
the purpose of discovery, shall be broadly permitted, and the provisions of 
CODE OF CIVIL PROCEDURE Section 1283.05 shall apply.  Any demand to 
arbitrate, for purposes of the statute of limitations, shall have the same 
effect as if suit had been filed on the date the demand is made.  The 
arbitration shall occur in Orange County, California.  The parties shall 
agree upon an arbitrator twenty-one (21) days after the demand is made, and 
if the parties fail to so agree, then any of them may apply to the court for 
an order appointing an arbitrator meeting the requirements of this section.  
The decision of the arbitrator shall be final and binding, and shall be 
subject to confirmation, correction or vacation in accordance with the 
provisions of Code of Civil Procedure Sections 1285-1287.4.  Any application, 
petition or other proceeding (i) to enforce the award or the provisions of 
this Agreement, (ii) to the extent that the arbitrator does not have the 
power or authority to resolve or grant the relief sought, and/or (iii) for 
provisional or equitable relief pending appointment of the arbitrator, shall 
be commenced in the appropriate state or federal courts having jurisdiction 
in Orange County, California and the parties hereby consent to jurisdiction 
and venue in such courts.  The decision of the arbitrator about the validity 
of any claim in a Premier Certificate shall be binding and conclusive on the 
parties to this Agreement; and notwithstanding anything to the contrary in 
this Escrow Agreement, Escrow Holder shall make or withhold distributions of 
the Escrow Shares or otherwise act in accordance with the arbitrator's 
decision.  The prevailing party in the arbitration, as determined by the 
arbitrator, shall be entitled to reimbursement of any costs or expenses 
incurred by it in connection with any mediation or arbitration hereunder, 
except to the extent decided to the contrary by the arbitrator.  Judgment on 
any award rendered by the arbitrator may be entered in any court having 
jurisdiction over the matter.

          10.  FINAL DISTRIBUTION OF ESCROW SHARES.  Upon expiration of the 
Escrow Period and receipt of written authorization from Premier, Escrow 
Holder shall distribute to Escrow Shareholders all shares then remaining in 
the escrow, except (a) such number of Escrow Shares as are sufficient, in the 
reasonable judgment of Premier to satisfy any unsatisfied claims specified in 
any Premier Notice or Premier Certificate previously delivered to Escrow 
Holder; (b) such number of Escrow Shares as are sufficient, in the reasonable 
judgment of the EyeSys 

                                    -5-



Representative to pay the costs and expenses incurred or likely to be 
incurred by the EyeSys Representative, and (c) the fees and disbursements of 
the Escrow Holder.  As soon as all claims have been resolved, Escrow Holder 
shall distribute to the EyeSys Shareholders all shares then remaining in the 
escrow not required to satisfy those claims, amounts due to the EyeSys 
Representative and the unpaid fees and disbursements of the Escrow Holder.  
Distributions of the remaining Escrow Shares to the EyeSys Shareholders 
pursuant to this Escrow Agreement, whenever made, shall be proportionate to 
the EyeSys Shareholders respective interests as determined pursuant to 
Section 2.2 of the Merger Agreement.

          11.  DISPOSITION OF ESCROWED DISSENTING SHARES.  In the event the 
Principal Shareholder (as defined in the Merger Agreement) sells any shares 
and remits the proceeds thereof to Premier pursuant to Section 5.22 of the 
Merger Agreement, upon the notification to Escrow Holder of such sale and 
acknowledgment of receipt by Premier of such proceeds, Escrow Holder shall 
distribute to the Principal Shareholder, out of the Escrowed Dissenting 
Shares, shares of Premier Class A Common Stock in an amount equal to the 
number of shares sold by the Principal Shareholder.  At such time as the 
Principal Shareholder has no further obligations under Section 5.22 of the 
Merger Agreement, all of the Escrowed Dissenting Shares then remaining in the 
Escrow shall be returned to Premier.

          12.  LIABILITY AND INDEMNIFICATION OF ESCROW HOLDER AND THE EYESYS
REPRESENTATIVE.

               (a)  In performing any duties under this Escrow Agreement, 
neither Escrow Holder nor the EyeSys Representative shall be liable to any 
party hereto for damages, losses or expenses, except for gross negligence or 
willful misconduct on the part of the Escrow Holder.  Escrow Holder shall not 
incur any such liability for (i) any act or failure to act made or omitted in 
good faith, or (ii) any action taken or omitted in reliance upon any 
instrument, including any written statement or affidavit provided for in this 
Agreement, that Escrow Holder shall in good faith believe to be genuine, nor 
shall Escrow Holder be liable or responsible for forgeries, fraud, 
impersonations, or determining the scope of any representative authority.  
Escrow Holder is not responsible for determining and verifying the authority 
of any person acting or purporting to act on behalf of any party to this 
Escrow Agreement.

               (b)  The parties hereto agree jointly and severally to 
indemnify and hold Escrow Holder harmless against any and all losses, claims, 
damages, liabilities, and expenses, including reasonable costs of 
investigation, reasonable attorneys' fees and disbursements that may be 
imposed on or incurred by Escrow Holder in connection with the performance of 
Escrow Holder's duties under this Agreement, including but not limited to any 
litigation arising from this Agreement or involving its subject matter, but 
excluding any losses, claims, damages, liabilities and expenses (including 
costs of investigation, attorneys' fees and disbursements) resulting from 
Escrow Holder's negligence or willful misconduct.

               (c)  Notwithstanding the foregoing, the EyeSys Representative 
shall have no personal responsibility with respect to any actions taken or 
not taken in connection with the performance of his obligations hereunder.  
To the extent that the EyeSys Representative may incur costs or expenses 
under this Agreement, including with respect to the indemnity provided 

                                    -6-



to the Escrow Holder, such obligations shall be satisfied solely by the 
Escrow Shares, subject to the prior satisfaction of any rights of Premier to 
reimbursement from the Escrow Shares.

Ladies and Gentlemen:

     The undersigned understands that you have entered into that certain 
Agreement and Plan of Merger dated as of ______________, 1997, by and among 
Premier Laser Systems, Inc., a California corporation ("PREMIER"), Premier 
Acquisition, Inc., a California corporation, and a wholly owned subsidiary of 
Premier, and EyeSys Technologies, Inc., a Delaware corporation (the "MERGER 
AGREEMENT"), which provides for the issuance of Class A Common Stock, no par 
value, of Premier ("COMMON STOCK") pursuant to Premier's Registration 
Statement on Form S-4 filed with the Securities and Exchange Commission on 
____________, 1997 (Registration No. 333-_______) (as may be amended or 
supplemented, the "REGISTRATION STATEMENT").  For purposes hereof, the term 
"PRIMARY EYESYS SHAREHOLDER GROUP" shall mean the ___ former holders of 
EyeSys securities who receive the largest number of shares of Common Stock as 
a result of the transactions described in the Merger Agreement.

     In consideration of the foregoing and in acknowledgment of the benefit 
therefrom to the undersigned, and for other good and valuable consideration, 
receipt of which is hereby acknowledged, the undersigned hereby agrees:  
(i) for a period of four and one-half (4 1/2) months from the Effective Time 
(as defined in the Merger Agreement), not to offer for sale, sell or 
otherwise dispose of (or enter into any transaction which is designed to, or 
could be expected to, result in the disposition by any person of), directly 
or indirectly (collectively, a "DISPOSITION") any of the shares of Common 
Stock, any then-vested options or any then-vested warrants to purchase any 
shares of Common Stock or any securities convertible into or exchangeable for 
shares of Common Stock (collectively, "SECURITIES"), now owned by the 
undersigned; and (ii) for a period commencing at the end of such four and 
one-half (4 1/2) month period and ending November 30, 1997, an amount which, 
when added to all other Dispositions by the Primary EyeSys Shareholder Group, 
does not exceed 65,000 shares per month, and thereafter, during each month, 
an amount equal to one-ninth (1/9) of the number of shares held by such 
person on November 30, 1997; provided, however, that if at any time Premier 
notifies the undersigned that it will commence within thirty (30) days a 
"call" with respect to Premier's outstanding Class A or Class B Warrants, the 
undersigned will not make any further Dispositions until the termination of 
such call (provided that the foregoing suspension of dispositions shall 



not exceed ninety (90) days in length).  The restrictions set forth in 
section (i) above are expressly agreed to preclude the holder of the 
Securities from engaging in any hedging or other transaction which is 
designed to or reasonably expected to lead to or result in a Disposition of 
Securities during the four and one-half (4 1/2) month lock-up period, even if 
such Securities would be disposed of by someone other than the undersigned.

     Notwithstanding any other provision of this Agreement to the contrary, 
in no event shall the undersigned offer for sale, sell or otherwise dispose 
of any Securities received pursuant to the Merger Agreement in an amount or 
manner which violates Rule 145(d) promulgated under the Securities Act of 
1933, as amended.

     Furthermore, the undersigned hereby agrees and consents to the entry of 
stop-transfer instructions with Premier's transfer agent against the transfer 
of the Securities held by the undersigned except in compliance with this 
Lock-Up Agreement.
