Item 2:  Other Events.

On May 3, 1996, Palomar Medical Technologies,  Inc., a Delaware corporation (the
"Company"),  through its  wholly-owned  subsidiary,  TTI  Acquisition  Corp., an
Arizona corporation  ("Sub"),  acquired all of the assets and business of Tissue
Technologies,  Inc.,  also an  Arizona  corporation  ("TTI"),  through a reverse
triangular  merger (the  "Merger").  TTI  manufactures  and sells a patented and
FDA-approved  carbon dioxide laser system for skin resurfacing that will augment
Palomar's family of proprietary  laser systems for medical,  dermatological  and
cosmetic treatments.  Pursuant to the Merger, the Company issued an aggregate of
3,200,000  shares  of its  common  stock,  $.01  par  value  per  share,  to the
stockholders  of TTI (the  "Palomar  Shares").  The  Merger  is  intended  to be
accounted for as a pooling of  interests.  In  connection  with the Merger,  the
Company has agreed to register the Palomar Shares.

                      AGREEMENT AND PLAN OF REORGANIZATION

         THIS AGREEMENT AND PLAN OF REORGANIZATION  (the "Agreement") is entered
into as of March 9, 1996, by and among  PALOMAR  MEDICAL  TECHNOLOGIES,  INC., a
Delaware corporation ("Palomar"),  TTI ACQUISITION CORP., an Arizona corporation
and a wholly-owned subsidiary of Palomar ("Sub"), TISSUE TECHNOLOGIES,  INC., an
Arizona   corporation   ("TTI"),   and  Mario   Barton,   an   individual   (the
"Stockholder").

                                    RECITALS

                  A. The parties desire that Palomar acquire TTI in a "statutory
merger"  pursuant to which Sub will be merged with and into TTI (the  "Merger"),
with  TTI  being  the  surviving  corporation  of  the  Merger  (the  "Surviving
Corporation")  on the terms and  conditions  set forth  herein  and in a Plan of
Merger in  substantially  the form  attached  hereto as  Exhibit A (the "Plan of
Merger").

                  B. As a result of the Merger,  TTI shall become a wholly-owned
subsidiary of Palomar and the  shareholders of TTI shall become  shareholders of
Palomar.

                  C. The Merger is  intended  to be  treated  as: (i) a tax-free
reorganization   pursuant  to  the  provisions  of  Section   368(a)(1)(A)   and
368(a)(2)(E) of the Internal Revenue Code of 1986, as amended (the "Code");  and
(ii) a "pooling of interests" for financial reporting purposes.

         NOW, THEREFORE, the parties hereto hereby agree as follows:

1.       PLAN OF REORGANIZATION

                  1.1 THE MERGER.  Subject to the terms and  conditions  of this
Agreement,  Sub will be merged with and into TTI in a statutory  merger pursuant
to the Plan of Merger and in accordance  with  applicable  provisions of Arizona
law as follows:

                  (a)  CONVERSION OF SUB SHARES.  At the  effective  time of the
Merger, as specified in the Plan of Merger (the "Effective Time"), each share of
Common Stock of Sub issued and  outstanding  immediately  prior to the Effective
Time  shall,  by virtue of the Merger and  without any action on the part of the
holder thereof,  be converted into and become one fully paid and  non-assessable
share of Common Stock of the Surviving Corporation.

                  (b)  CONVERSION  OF TTI SHARES.  At the Effective  Time,  each
share of the common stock, without par value, of TTI ("TTI Common Stock") issued
and outstanding immediately prior to the Effective Time, by virtue of the Merger
and without  any action on the part of the holder  thereof,  shall be  converted
into the right to receive  that number of shares of the common  stock,  $.01 par
value per share, of Palomar  ("Palomar  Common Stock") which equals  $20,000,000
divided by the lesser of (1) $6.25 or (2) the  average  closing  "ask" price for
Palomar  Common  Stock for the ten (10) trading  days  immediately  prior to the
Closing  (as  defined  in  Section  7.1  below),  as quoted on the  NASDAQ  (the
"Conversion  Price")  divided by




the total number of shares of TTI Common Stock  outstanding  immediately  before
the Effective Time.

                  (c) ADJUSTMENT FOR STOCK SPLITS. The Conversion Price shall be
appropriately  adjusted  for any stock split or  combination  of Palomar  Common
Stock, any  reclassification or recapitalization of Palomar Common Stock, or any
dividend on Palomar Common Stock payable in securities of Palomar, with a record
date on or after the date hereof and on or before the Effective Time.

                  1.2 FRACTIONAL  SHARES. No fractional shares of Palomar Common
Stock shall be issued in connection with the Merger.  In lieu thereof,  each TTI
shareholder  who would otherwise be entitled to receive a fraction of a share of
Palomar  Common Stock will receive from  Palomar,  promptly  after the Effective
Time, an amount of cash equal to the Conversion Price multiplied by the fraction
of a share of Palomar Common Stock to which such shareholder  would otherwise be
entitled.

                  1.3  EFFECTS OF THE MERGER.  At the  Effective  Time:  (a) the
separate  existence of Sub will cease, and Sub will be merged with and into TTI,
and TTI will be the surviving corporation,  pursuant to the terms of the Plan of
Merger;  (b) the  Articles  of  Incorporation  and  Bylaws of TTI will  continue
unchanged  as  the  Articles  of  Incorporation  and  Bylaws  of  the  Surviving
Corporation, (c) each share of Sub Common Stock outstanding immediately prior to
the  Effective  Time will be  converted  into one  share of Common  Stock of the
Surviving   Corporation;   (d)  each  share  of  TTI  Common  Stock  outstanding
immediately prior to the Effective Time will be converted into shares of Palomar
Common Stock in accordance with Section 1.1(b) hereof;  and (e) the Merger will,
from  and  after  the  Effective  Time,  have  all of the  effects  provided  by
applicable law.

                  1.4 FURTHER ASSURANCES. TTI, Sub and Palomar hereby agree that
they will  cause to be  executed  and  filed and will  record  any  document  or
documents  prescribed by the laws of the State of Arizona or any other state and
that they will cause to be performed all necessary or desirable  acts within the
State of Arizona and  elsewhere to  effectuate  the Merger  provided for herein,
including,  without  limitation,  execution,  filing and delivery of any further
deeds,  assignments  or  assurances  necessary or desirable to vest,  perfect or
confirm in the Surviving Corporation title to all property and rights of Sub and
TTI.

                  1.5 TAX FREE REORGANIZATION.  The parties intend to adopt this
Agreement as a tax-free plan of  reorganization  and to consummate the Merger in
accordance with the provisions of Sections  368(a)(1)(A) and 368(a)(2)(E) of the
Code,  and the parties  agree not to take any  position  inconsistent  with this
intention.  The Palomar Common Stock issued in the Merger shall be issued solely
in  exchange  for the TTI  Common  Stock  pursuant  to  this  Agreement,  and no
transaction other than the Merger represents, provides for or is intended to be,
an adjustment to the consideration paid for the TTI Common Stock.


                                      -2-


                  1.6 POOLING OF INTERESTS.  The parties  intend that the Merger
be treated as a "pooling of interests" for accounting purposes.

2.       REPRESENTATIONS AND WARRANTIES OF TTI.

         TTI hereby represents and warrants that, except as set forth on the TTI
Schedule of Exceptions attached hereto as Schedule 2:

                  2.1 ORGANIZATION AND GOOD STANDING.  TTI is a corporation duly
organized,  validly existing and in good standing under the laws of the State of
Arizona,  has the corporate  power and  authority to own,  operate and lease its
properties  and to carry on its business as now  conducted and as proposed to be
conducted, and is qualified as a foreign corporation in New Mexico. TTI does not
own or lease real property,  have employees or conduct intrastate business,  nor
is it required to be qualified to do business,  in any jurisdictions  other than
New Mexico.

                  2.2 POWER, AUTHORIZATION AND VALIDITY.

                  (a) TTI has the corporate right,  power and authority to enter
into and perform its  obligations  under this  Agreement,  and all agreements to
which it is or will be a party that are required to be executed pursuant to this
Agreement, including, without limitation, the Plan of Merger (the "TTI Ancillary
Agreements").  The execution, delivery and performance of this Agreement and the
TTI Ancillary  Agreements  has been duly and validly  approved and authorized by
the  Board of  Directors  of TTI and will be duly and  validly  approved  by the
unanimous vote of the shareholders of TTI prior to the Effective Time.

                  (b) No filing,  authorization  or  approval,  governmental  or
otherwise,  is  necessary  to  enable  TTI to enter  into,  and to  perform  its
obligations under, this Agreement and the TTI Ancillary Agreements,  except for:
(a) the filing of  Articles  of Merger and the Plan of Merger  with the  Arizona
Secretary  of State and the filing of  appropriate  documents  with the relevant
authorities  in New Mexico;  (b) such  filings and permits as may be required to
comply with  federal and state  securities  laws;  and (c) the  approval of this
Agreement and the Plan of Merger by the TTI shareholders.

                  (c) This  Agreement and the TTI Ancillary  Agreements  are, or
when executed by TTI will be, valid and binding  obligations of TTI  enforceable
in accordance with their respective terms,  except as to the effect, if any, of:
(a)  applicable  bankruptcy  and other  similar  laws  affecting  the  rights of
creditors generally; (b) rules of law governing specific performance, injunctive
relief and other equitable  remedies;  and (c) the  enforceability of provisions
requiring  indemnification in connection with the offering,  issuance or sale of
securities.

                  2.3  CAPITALIZATION.  The  authorized,  issued and outstanding
capital  stock of TTI is set forth on Schedule  2.3. All issued and  outstanding
shares of TTI Common Stock are owned  beneficially  and of record by the persons
set forth on Schedule 2.3 and have been duly


                                      -3-


authorized and validly issued, are fully paid and nonassessable, are not subject
to any right of rescission, and have been offered, issued, sold and delivered in
compliance with all  registration or  qualification  requirements (or applicable
exemptions therefrom) of applicable federal and state securities laws. Except as
set forth on Schedule 2.3, there are no options, warrants, conversion privileges
or preemptive or other rights or agreements outstanding to purchase or otherwise
acquire  any  of  TTI's  authorized  but  unissued  capital  stock  ("Derivative
Securities") or any agreements to issue Derivative  Securities,  and there is no
liability for dividends accrued but unpaid. Prior to the Effective Time, each of
the  Derivative  Securities  shall have been exercised for or converted into TTI
Common  Stock and the shares of TTI Common  Stock  issued upon such  exercise or
conversion  shall have been duly authorized and validly  issued,  shall be fully
paid and  nonassessable,  shall not be subject to any right of  rescission,  and
shall have been  offered,  issued,  sold and  delivered in  compliance  with all
registration or qualification  requirements (or applicable exemptions therefrom)
of applicable federal and state securities laws. There are no voting agreements,
rights of first refusal or other restrictions (other than normal restrictions on
transfer under  applicable  federal and state securities laws) applicable to any
of TTI's outstanding securities.

                  2.4  SUBSIDIARIES.  TTI has no  subsidiaries  nor  any  equity
interest, direct or indirect, in any corporation,  partnership, joint venture or
other  business  entity.  TTI is  autonomous  and has not been a  subsidiary  or
division  of another  corporation  within  two years of the date  hereof for the
purposes of Accounting Principles Board Opinion Number 16.

                  2.5 NO VIOLATION OF EXISTING AGREEMENTS. Neither the execution
nor  delivery  of  this  Agreement  or any  TTI  Ancillary  Agreement,  nor  the
consummation of the transactions  contemplated hereby or thereby,  will conflict
with,  or (with or  without  notice  or lapse  of  time,  or both)  result  in a
termination,  breach,  impairment  or  violation  of: (a) any  provision  of the
Articles of Incorporation  or Bylaws of TTI, as currently in effect;  (b) in any
material respect, any material instrument or contract to which TTI is a party or
by which TTI is bound;  or (c) any federal,  state,  local or foreign  judgment,
writ, decree, order, statute, rule or regulation applicable to TTI or its assets
or properties.  The  consummation  of the Merger will not require the consent of
any third  party and will not have a material  adverse  effect  upon any rights,
licenses, franchises, leases or agreements of TTI pursuant to the terms of those
agreements.

                  2.6  LITIGATION.  There  is no  action,  proceeding,  claim or
investigation  pending  against TTI before any court or  administrative  agency,
and, to the best of the  knowledge of TTI, no such action,  proceeding  claim or
investigation  has been  threatened.  There is no basis for any  shareholder  or
former shareholder of TTI, or any other person, firm,  corporation or entity, to
assert a claim against TTI, Sub or Palomar  based upon:  (a) ownership or rights
to  ownership  of any  shares of TTI  Common  Stock;  or (b) any rights as or to
become a TTI  shareholder,  between  TTI and any of its  shareholders  or former
shareholders in their capacity as such.

                  2.7 TTI FINANCIAL STATEMENTS.  Attached hereto as Schedule 2.7
are copies of TTI's  unaudited  balance  sheets as of December  31, 1995 and the
related unaudited statements of income, shareholders' equity and changes in cash
flow for the years then ended (collectively,


                                      -4-


"TTI  Financial  Statements").  The TTI  Financial  Statements:  (a)  have  been
prepared in accordance with generally accepted  accounting  principles  ("GAAP")
except  that the  unaudited  statements  do not  contain  notes,  and (b) fairly
present the financial condition of TTI at the respective dates therein indicated
and the results of operations for the respective periods therein specified.  TTI
has no material debt,  liability or obligations of any nature,  whether accrued,
absolute, contingent or otherwise, and whether due or to become due, that is not
reflected, reserved against or disclosed in the Balance Sheet as of December 31,
1995  (the  "Financial  Statement  Date"),  except  for (i)  those  that are not
required  to be  reported  in  accordance  with  generally  accepted  accounting
principles and are disclosed by TTI in writing to Palomar to the extent required
pursuant to Section 4.1 hereof and (ii) those that may have been incurred  after
the  Financial  Statement  Date  in  the  ordinary  course  of  TTI's  business,
consistent with past practice.

                  2.8 TAXES. TTI has filed all federal, state, local and foreign
tax and information returns required to be filed, has paid all taxes required to
be paid in  respect  of all  periods  for which  returns  have been  filed,  has
established an adequate  accrual or reserve for the payment of all taxes payable
in respect of the periods  subsequent to the periods  covered by the most recent
applicable tax returns,  has made all necessary estimated tax payments,  and has
no  liability  for taxes in excess of the amount so paid or accruals or reserves
so established in the applicable  TTI Financial  Statements.  True,  correct and
complete  copies of all such tax and  information  returns have been provided or
made  available by TTI to Palomar.  TTI is not  delinquent in the payment of any
tax or the filing of any tax returns,  and no deficiencies for any tax have been
threatened,  claimed,  proposed or assessed  which have not been settled or paid
nor is TTI  aware of any  basis  for  such.  No tax  return of TTI has ever been
audited by the Internal Revenue Service or any state taxing agency or authority.
For the  purpose  of this  Section,  the terms  "tax" and  "taxes"  include  all
federal,  excise, state, local and foreign income, gains,  franchise,  property,
sales, use, employment, license, payroll, occupation,  according, value added or
transfer  taxes,  governmental  charges,  fees,  levies or assessments  (whether
payable  directly or by  withholding),  and,  with  respect to such  taxes,  any
estimated  tax,  interest and penalties or additions to tax and interest on such
penalties and additions to tax. TTI will not, as a result of the Merger,  become
liable for any income tax not adequately  reserved  against on the TTI Financial
Statements. TTI has not filed a consent pursuant to Section 341(f) of the Code.

                  2.9 TITLE TO PROPERTIES.  TTI has good and marketable title to
all of its assets as shown on its balance  sheet as of the  Financial  Statement
Date  included  in the TTI  Financial  Statement,  free and clear of all  liens,
charges,  encumbrances  (other  than for  taxes  not yet due and  payable).  The
machinery and equipment included in such properties are in all material respects
in good  condition and repair,  normal wear and tear  excepted,  and all leases,
real or personal property to which TTI is a party are fully effective and afford
TTI, as the case may be,  peaceful  and  undisturbed  possession  of the subject
matter of the lease.  TTI is not in violation of any zoning,  building,  safety,
environmental  ordinance,  regulation or  requirement or other law or regulation
applicable to the operation of its owned or leased  properties (the violation of
which would have a material  adverse  effect on its  business),  and TTI has not
received  any notice of such  violation  with which it has not  complied  or had
waived.

                                      -5-

Date,  except as contemplated by this transaction or disclosed on Schedule 2.10,

                  2.11  AGREEMENTS AND  COMMITMENTS.  Schedule 2.11 sets forth a
true,  correct and complete list of TTI's Material Contracts (as defined below).

                  (j) Contract  containing  covenants  purporting to limit TTI's
freedom to compete in any line of business in any geographic area.

                  (k)      Warranty, indemnity or guaranty agreements.

         All agreements,  obligations  and commitments  listed in Schedule 2.11,
Schedule 2.12,  Schedule 2.15(c) or Schedule 2.15(f) (the "Material  Contracts")
are valid and in full force and effect in all  material  respects and a true and
complete copy of each has been delivered to Palomar's  counsel.  TTI is not, and
to the best  knowledge  of TTI,  no other  party is, in breach or default in any
material  respect  under  the  terms  of  any  such  agreement,   obligation  or
commitment,  which  breach or  default  may  reasonably  be  expected  to have a
material  adverse  effect  on  TTI.  TTI  is not a  party  to  any  contract  or
arrangement  which it reasonably  expects will have a material adverse effect on
its business or prospects.  TTI has no material  liability for  renegotiation of
government  contracts or  subcontracts,  if any. Each  Material  Contract can be
performed without a loss to TTI or Sub.

                  2.1  INTELLECTUAL  PROPERTY.  TTI owns all  right,  title  and
interest in, or has the right to use, free and clear of all security  interests,
liens and encumbrances,  all patents,  trademarks, trade dress, designs, service
marks, trade names, mask works, copyrights, trade secrets, know-


                                      -8-


how,  technology  and  other  intellectual   property  and  proprietary  rights,
including, without limitation, all patent, trademark and copyright registrations
and applications for the registration  thereof,  necessary to the conduct of its
business as  presently  conducted  and as proposed  to be  conducted  including,
without limitation,  the trademark  "Tru-Pulse" and all items listed in Schedule
2.12 ("Intellectual  Property"). All Intellectual Property created by or for TTI
was created  solely by full-time,  regular  employees of TTI within the scope of
their  employment and TTI has obtained from each employee an executed  agreement
pursuant  to  which  the  employee  assigned  to TTI  (and  to the  extent  such
assignment  could not be made at the time of execution of the agreement,  agreed
to assign to TTI) all of the employee's right,  title and interest in and to any
of the  Intellectual  Property  and agreed to maintain in  confidence  any trade
secrets or  confidential  information  of TTI. TTI has taken  measures  which it
believes are  reasonable to protect all  Intellectual  Property and are at least
consistent with industry  practice,  and TTI is not aware of any infringement of
such Intellectual  Property by any third party. Schedule 2.12 attached hereto is
a true and complete list of all  Intellectual  Property owned or licensed by TTI
and  such  schedule  distinguishes  Intellectual  Property  owned  by  TTI  from
Intellectual   Property  licensed  by  TTI.  No  material  loss,   cancellation,
termination or expiration of any copyright or trademark  registration  or patent
nor any  opposition to any  registration  or  application  for  registration  is
foreseeable by TTI except as set forth on Schedule 2.12. TTI represents  that it
has timely paid all maintenance fees for all patents and trademark and copyright
registrations  listed on  Schedule  2.12 and that no  patents  or  copyright  or
trademark  registrations listed on Schedule 2.12 have expired for failure to pay
maintenance  fees. TTI is not using any trademarks,  tradenames,  trade dress or
service marks in commerce  other than those listed on Schedule  2.12.  Copies of
all forms of non-disclosure or  confidentiality  agreements  utilized to protect
such Intellectual  Property have been provided or made available to Palomar. The
business of TTI as  presently  conducted  and as proposed to be conducted by TTI
does not and, to the best  knowledge  of TTI,  will not cause TTI to infringe or
violate any of the patents,  trademarks,  trade dress,  designs,  service marks,
trade names, mask works,  copyrights,  trade secrets,  know-how,  technology and
other intellectual property and proprietary rights (including without limitation
moral and personal  rights),  of any other person,  and TTI has not received any
claim or notice of infringement or potential  infringement of such rights of any
other person which could be expected to have a material  adverse effect on TTI's
business.

                  2.13   COMPLIANCE   WITH  LAWS.  TTI  has  complied  with  all
applicable  laws,  ordinances,  regulations  and rules,  and all  orders,  writs
injunctions,  awards, judgments and decrees, applicable to TTI or to its assets,
properties  and business (the  violation of which would have a material  adverse
effect upon TTI), including,  without limitation: (a) all applicable federal and
state securities laws and  regulations;  (b) all applicable  federal,  state and
local laws,  ordinances and  regulations,  and all orders,  writs,  injunctions,
awards, judgments and decrees,  pertaining to (i) the sale, licensing,  leasing,
ownership  or  management  of TTI's owned,  leased or licensed  real or personal
property, products and technical data, (ii) employment and employment practices,
terms and  conditions  of  employment,  and wages and hours,  and (iii)  safety,
health,  fire  prevention,   environmental  protection  (including  toxic  waste
disposal  and  related  matters  described  in Section  2.21  hereof),  building
standards,  zoning and other similar matters; and (c) the Export  Administration
Act and  regulations  promulgated  thereunder  and all other laws,


                                      -9-


regulations, rules, orders, writs, injunctions, judgments and decrees applicable
to  the  export  or  re-export  of  controlled  commodities  or  technical  data
controlled  under the Export  Administration  Act. TTI has received all material
permits and  approvals  from,  and have made all material  filings  with,  third
parties,  including  government agencies and authorities,  that are necessary in
connection with its present business.

                  2.14 CERTAIN TRANSACTIONS AND AGREEMENTS. None of the officers
or  directors of TTI, nor any member of any  officer's or  director's  immediate
family, has any direct or indirect ownership interest in any firm or corporation
that  competes  with TTI  (except  with  respect to any  interest  that is not a
material  portion of the assets of such  person and is less than one  percent of
the stock of any  corporation  whose  stock is  publicly  traded).  None of such
officers or directors,  or any member of any  officer's or director's  immediate
family,  is or has been  directly or  indirectly  interested  in any contract or
informal  arrangement  with  TTI,  within  the  last  three  years,  except  for
compensation  for services as an officer,  director or employee of TTI.  None of
such  officers or directors or family  members has any interest in any property,
real  or  personal,  tangible  or  intangible,  including  but  not  limited  to
Intellectual Property, used in the business of TTI, except for the normal rights
of a shareholder.

                  2.15 EMPLOYEES.

                  (a)  Schedule  2.15(a)  contains  a  list  of  all  employment
contracts  currently in effect that are not  terminable  at will without cost to
TTI  (other  than  agreements  with  the  sole  purpose  of  providing  for  the
confidentiality  of proprietary  information or assignment of  inventions).  All
officers,  employees  and  consultants  of  TTI  having  access  to  proprietary
information of TTI have executed and delivered to TTI an agreement regarding the
protection of such  proprietary  information and the assignment of inventions to
TTI.

                  (b) TTI has:  (i) never been and is not now subject to a union
organizing effort;  (ii) is not subject to any collective  bargaining  agreement
with  respect  to any of its  employees;  (iii)  is  not  subject  to any  other
contract, written or oral, with any trade or labor union, employees' association
or similar organization; and (iv) has no material current labor dispute. TTI has
good labor  relations,  and has no  knowledge of any facts  indicating  that the
consummation  of the  transactions  contemplated  hereby  will  have a  material
adverse effect on such labor relations, and has no knowledge that any of its key
employees intends to leave its employ.

                  (c)  Schedule   2.15(c)   contains  a  list  of  all  pension,
retirement, disability, medical, dental or other health plans, life insurance or
other death benefit plans,  profit sharing,  deferred  compensation  agreements,
stock, option, bonus or other incentive plans, vacation,  sick, holiday or other
paid leave  plans,  severance  plans or other  similar  employee  benefit  plans
maintained by TTI (the "Employee Plans"),  including,  without  limitation,  all
"employee  benefit plans" as defined in Section 3(3) of the Employee  Retirement
Income Security Act of 1974, as amended  ("ERISA").  Each of the Employee Plans,
and  its  operation  and  administration,  is,  in  all  material  respects,  in
compliance with all applicable federal, state, local and other


                                      -10-


governmental laws and ordinances,  orders, rules and regulations,  including the
requirements  of ERISA and the Code.  All such Employee Plans that are "employee
pension  benefit  plans" (as  defined in Section  3(2) of ERISA)  have  received
favorable  determination  letters  that such  plans  satisfy  the  qualification
requirements  of the Tax  Equity  and  Fiscal  Responsibility  Act of 1982,  the
Deficit  Reduction  Act of 1984  and  the  Retirement  Equity  Act of  1984.  In
addition, TTI has not been a participant in any "prohibited transaction," within
the  meaning of Section  406 of ERISA,  with  respect  to any  employee  pension
benefit  plan (as  defined  in  Section  3(2) of ERISA)  which TTI  sponsors  as
employer  or in which TTI  participates  as  employer,  which was not  otherwise
exempt  pursuant to Section 408 of ERISA  (including  any  individual  exemption
granted under Section  408(a) of ERISA),  or which could result in an excise tax
under the Code.  The group  health  plans,  as defined in Section  498(g) of the
Code,  that benefit  employees of TTI are in  compliance  with the  continuation
coverage  requirements  of  Subsection  4980B(g)  of  the  Code.  There  are  no
outstanding violations of Section 4090B of the Code with respect to any Employee
Plan, covered employees or qualified beneficiaries.

                  (d) To the best  knowledge  of TTI,  no  employee of TTI is in
material  violation  of:  (a)  any  term  of  any  employment  contract,  patent
disclosure agreement or noncompetition  agreement;  or (b) any other contract or
agreement,  or any  restrictive  covenant,  relating  to the  right  of any such
employee  to be  employed  by  TTI  or  to  use  trade  secrets  or  proprietary
information  of others.  To the best  knowledge  of TTI, the  employment  of any
employee of TTI does not subject TTI to any liability to any third party.

                  (e)  TTI is  not a  party  to  any:  (a)  agreement  with  any
executive  officer or other key  employee  of TTI (i) the  benefits of which are
contingent, or the terms of which are materially altered, upon the occurrence of
a  transaction   involving  TTI  in  the  nature  of  any  of  the  transactions
contemplated by this Agreement and the TTI Ancillary Agreements,  (ii) providing
any term of employment or compensation  guarantee,  or (iii) providing severance
benefits or other benefits after the  termination of employment of such employee
regardless of the reason for such termination of employment, or (b) agreement or
plan, including,  without limitation,  any stock option plan, stock appreciation
rights  plan or stock  purchase  plan,  any of the  benefits  of  which  will be
increased,  or the vesting of benefits of which will be  calculated on the basis
of any of the  transactions by this Agreement and the TTI Ancillary  Agreements.
TTI is not obligated to make any excess parachute payment, as defined in Section
280G(b)(1) of the Code, nor will any excess parachute  payment be deemed to have
occurred as a result of or arising out of the Merger.

                  (f) A list  of  ongoing  employees,  officers  and  technical,
engineering and development consultants of TTI and their current compensation is
forth on Schedule 2.15(f) attached hereto.

                  (g) All  contributions due from TTI with respect to any of the
Employee Plans have been made or accrued on TTI's financial  statements,  and no
further  contributions  will be due or will have  accrued  thereunder  as of the
Closing Date.


                                      -11-

origin,  negotiations  or  execution  of this  Agreement  or the  TTI  Ancillary
Agreements or in connection with any transaction contemplated hereby or thereby.

                  2.18  DISCLOSURE.  Neither  this  Agreement,  its exhibits and
schedules,  nor any of the  certificates  or documents to be delivered by TTI to
Palomar under this Agreement, taken together, contains any untrue statement of a
material fact or omits to state any material fact necessary in order to make the
statements  contained herein and therein,  in light of the  circumstances  under
which such statements were made, not misleading.

                  2.19 BOOKS AND RECORDS.

                  (a) The books,  records and  accounts  of TTI:  (a) are in all
material  respects  true,  complete and  correct;  (b) have been  maintained  in
accordance with good business  practices on a basis consistent with prior years;
(c) are stated in  reasonable  detail and  accurately  and  fairly  reflect  the

fairly reflect the basis for the TTI Financial Statements.

                  (b) TTI  has  devised  and  maintains  a  system  of  internal
accounting  controls  sufficient  to provide  reasonable  assurances  that:  (i)
transactions  are executed in accordance with  management's  general or specific
authorization;  (ii)  transactions  are  recorded  as  necessary  (1) to  permit
preparation  of financial  statements  in  conformity  with  generally  accepted
accounting  principles or any other criteria  applicable to such  statements and
(2) to maintain  accountability  for assets;  and (iii) the amount  recorded for
assets on the books and records of TTI is compared  with the existing  assets at
reasonable  intervals  and  appropriate  action  is taken  with  respect  to any
differences.

                  2.20 INSURANCE. TTI maintains the insurance policies listed on
Schedule 2.20. The insurance  policies listed and described  briefly on Schedule
2.20  constitute  all of the  policies  in force and  effect in  respect  of the
business,  properties and assets,  including,  without limitation,  insurance on
personnel,  of TTI. TTI is not in default  under any such policy.  The insurance
policies so listed and identified are sufficient in nature, scope and amounts to
insure adequately (and, in any event, in amounts  sufficient to prevent TTI from

                                      -12-


terms of such policies) the business,  properties and assets of TTI. TTI has not

adverse  effect upon the  business or  financial  statements  of TTI. TTI has no
knowledge  of any  presence,  disposals,  releases  or  threatened  releases  of

purpose similar to those identified above.

                  (b) None of the  properties  leased by TTI are known by TTI to
be in  material  violation  of any  federal,  state  or  local  law,  ordinance,
regulation  or order  relating  to  industrial  hygiene or to the  environmental
conditions in such  properties,  including,  but not limited to, soil and ground
water condition.

                  (c) During the time that TTI has  leased its  properties,  TTI
has  not,  nor to its best  knowledge,  has any  third  party  used,  generated,

relating to any of TTI's  contracts with any Government  Contract Party that has
led to or reasonably could lead to, either before or after the Closing Date: (i)
any material  claim or dispute  involving TTI and/or  Palomar and any Government
Contract Party; or (ii) any suspension,  debarment or contract  termination,  or
proceeding related thereto which could be reasonably expected to have a material
adverse  effect on TTI. TTI represents and warrants that it has no knowledge of,
and has no reason to know of, any acts or omissions relating to the licensing or
selling to any Government  Contract Party,  or marking,  of any of TTI technical
data or computer  software,  that has led to or reasonably could lead to, either
before or after the Closing Date,  any material  cloud on any of TTI's rights in
and to  its  technical  data  or  computer  software,  and  that  all  of  TTI's
development of technical data and computer software was developed exclusively at
private  expense.  For  purposes  of this  Section  2.22,  the term  "Government
Contract   Party"  means  any   independent  or  executive   agency,   division,
subdivision,  audit  group,  or  procuring  office  of the  federal  government,
including any prime  contractor of the federal  government  and any higher level
subcontractor of a prime contractor of the federal government, and including any

obligations  under this Agreement and the Palomar Ancillary  Agreements,  except

permits as may be required to comply with federal and state securities laws.

as to the effect,  if any, of: (i) applicable  bankruptcy and other similar laws
affecting  the  rights  of  creditors  generally;  (ii)  rules of law  governing
specific performance,  injunctive relief and other equitable remedies; and (iii)
the  enforceability of provisions  requiring  indemnification in connection with

authorized  capital  stock of Palomar  consists of  40,000,000  shares of Common
Stock  and  5,000,000  shares  of  preferred  stock.  $.01 par  value  per share

                  3.4 SEC  DOCUMENTS;  FINANCIAL  STATEMENTS.  Palomar  has made
available to TTI a true and complete copy of each report, schedule, registration
statement and definitive  proxy  statement  filed by Palomar with the Securities
Exchange  Commission  (the  "Commission")  since  December  20,  1994  (as  such
documents  have since the time of their  filing been  amended,  the "Palomar SEC
Documents"),  which are all the documents (other than preliminary material) that
Palomar was required to file with the  Commission  since such date.  As of their
respective  dates,  the Palomar SEC Documents  and any forms,  reports and other
documents  filed by Palomar  after the date of this  Agreement  complied or will
comply in all material  respects with the  requirements of the Securities Act of
1933, as amended (the "Securities Act"), or the Exchange Act of 1934, as amended
(the "Exchange  Act"),  as the case may be, and the rules and regulations of the
Commission  thereunder  applicable  to such Palomar SEC  Documents or such other
forms,  reports  or other  documents,  and  none of the  Palomar  SEC  Documents
contained, or will contain at the time they are filed, any untrue statement of a
material  fact or omitted,  or will omit at the time they are filed,  to state a
material fact required to be stated  therein or necessary to make the statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.  The  financial  statements  of Palomar  included in the Palomar SEC
Documents comply as to form in all material respects with applicable  accounting
requirements and with the published rules and regulations of the Commission with
respect  thereto,  have been  prepared  in  accordance  with GAAP  applied  on a
consistent  basis during the periods involved (except as may be indicated in the
notes thereto or, in the case of the unaudited statements,  as permitted by Form
10-Q  of the  Commission)  and  fairly  present  (subject,  in the  case  of the
unaudited  statements,  to normal,  recurring audit adjustments,  which were not
individually  or in


                                      -15-


the  aggregate  material) in all material  respects  the  financial  position of
Palomar as at the dates thereof and the results of its operations and cash flows
for the periods then ended.

                  3.5  ABSENCE  OF CERTAIN  CHANGES.  Since the date of the most
recent Palomar SEC Document,  except as contemplated  by this  transaction or as
disclosed on Schedule 3.5, there has not been with respect to Palomar or Sub any
material  adverse change in the business,  results of operations or creditors of
Palomar or Sub.

                  3.6 NO BROKERS.  Palomar is not  obligated  for the payment of
fees or expenses of any investment  banker,  broker or finder in connection with
the origin,  negotiation or execution of this Agreement or the Palomar Ancillary
Agreements,  or in  connection  with  any  transaction  contemplated  hereby  or
thereby.

                  3.7 NO VIOLATION OF EXISTING AGREEMENTS. Neither the execution
nor  delivery of this  Agreement  or any Palomar  Ancillary  Agreement,  nor the
consummation of the transactions  contemplated hereby or thereby,  will conflict
with,  or (with or  without  notice  or lapse  of  time,  or both)  result  in a
termination,  breach,  impairment  or  violation  of: (a) any  provision  of the
Certificate  of  Incorporation  or Bylaws of Palomar  or Sub,  as  currently  in
effect;  (b) in any material  respect,  any material  instrument  or contract to
which  Palomar  or Sub is a party or by which  Palomar  or Sub is bound or which
Palomar or Sub will  become a party to or be bound by prior to the  Closing;  or
(c) any federal, state, local or foreign judgment, writ, decree, order, statute,
rule or regulation applicable to Palomar or Sub or their assets or properties.

this  Agreement)  or  consummation  of the Merger,  TTI shall not, and shall not
authorize or permit any officer, director,  employee or affiliate of TTI, or any
other person, on its behalf to, directly or indirectly, solicit or encourage any

6.       INDEMNIFICATION.

                  6.1 INDEMNIFICATION.

                  (a)  TTI  and  the  Stockholder  (collectively,  the  "Selling
Parties")   hereby  agree  to  indemnify,   defend  and  hold  Palomar  and  Sub
(collectively, the "Purchasing Parties") harmless from and against the amount of
any actual (or  potential in the case of any  litigation or claims by any person
not a  party  to this  Agreement)  damage,  loss,  cost  or  expense  (including
reasonable  attorneys' fees and settlement costs) ("Loss") to Purchasing Parties
occasioned or caused by, resulting from or arising out of:

                           (i) any  failure by TTI or  Stockholder  to  perform,
abide by or fulfill any of the agreements, covenants or obligations set forth in
or  entered  into in  connection  with  this  Agreement  to be so  performed  or
fulfilled by TTI or Stockholder; and/or

                           (ii)  any  inaccuracy  in or  breach  of  any  of the
representations or warranties set forth in this Agreement, or any certificate or
Schedule or other writing furnished to Palomar or Sub pursuant hereto.

                  (b) TTI's  obligation to indemnify the  Purchasing  Parties as
set forth in Section  6.1(a)  shall  apply prior to the  Effective  Time and the
Stockholder's  obligation  to indemnify the  Purchasing  Parties as set forth in
Section 6.1(a) shall apply after the Effective Time.

                  (c)  Palomar  hereby  agrees  to  defend  and hold TTI and its
shareholders  harmless from and against the amount of any actual Loss occasioned
or caused by, resulting from or arising out of:

                           (i) any failure by Palomar or Sub to  perform,  abide
by or fulfill any of the  agreements,  covenants or obligations  set forth in or
entered into in connection  with this  Agreement to be so performed or fulfilled
by Palomar or Sub; and/or


                                      -21-


                           (ii)  any  inaccuracy  in or  breach  of  any  of the
representations or warranties set forth in this Agreement, or any certificate or
Schedule or other writing furnished to TTI pursuant hereto.

         The  amount of any Loss shall be the  amount of cash  reimbursement  or
set-off that, when received by the indemnified  party incurring such loss, shall
place such  indemnified  party in the same  financial  position it or they would
have been in if such Loss had not occurred.

                  6.2   NOTICE  OF  CLAIM.   The  party  or   parties   claiming
indemnification  under Section 6.1 above (the "Indemnified  Parties") shall give
prompt  written  notice to the party or  parties  from whom  indemnification  is
sought (the "Indemnifying Parties") of any claim (actual or threatened) or other
event  which in the  judgment of the  Indemnified  Parties  might  result or has
resulted in a Loss by the Indemnified  Parties  hereunder,  and the Indemnifying
Parties  shall  have the  right  to  assume  the  defense  of such  claim or any
litigation  resulting  therefrom;  provided  that  counsel for the  Indemnifying
Parties,  who shall  conduct the defense of such claim  (actual,  threatened  or
asserted) or litigation,  shall be reasonably  satisfactory  to the  Indemnified
Parties and the  Indemnified  Parties may  participate  in such defense at their
expense, and provided,  further, that the omission by the Indemnified Parties to
give notice as provided  herein  shall not relieve the  Indemnifying  Parties of
their obligations  hereunder except to the extent that the omission results in a
failure  of  actual  notice to the  Indemnifying  Parties  and the  Indemnifying
Parties  are  damaged  solely  as a result of the  failure  to give  notice.  No
Indemnifying  Party,  in the  defense  of any such claim or  litigation,  shall,
except with the consent of each Indemnified  Party,  consent to the entry of any
judgment  or decree or enter into any  settlement  which does not  include as an
unconditional   term  thereof  the  giving  by  the  claimant  or  plaintiff  to
Indemnified  Parties of a release from all liability in respect to such claim or
litigation,  and no Indemnifying  Party shall have liability with respect to any
payment  made  by an  Indemnified  Party  in  connection  with  the  settlement,
satisfaction  or compromise of any claim unless the  Indemnifying  Parties shall
have approved  thereof in advance in writing.  If the Indemnified  Parties shall
not have received notice that the Indemnifying  Parties shall assume the defense
of  such  claim  within  twenty  (20)  days  after  the  notice  is  sent to the
Indemnifying  Parties of the existence of such claim,  the  Indemnified  Parties
shall be free to proceed with the defense of such claim.  Each such notice shall
be accompanied (or followed as promptly as is reasonably  practicable  after the
amount  of such  Loss  becomes  determinable)  by a  certificate  signed  by the
Indemnified  Party  (the  holders  of a  majority  of the shares of TTI or their
designated  representative  or the  President of Palomar or Sub, as the case may
be) and setting forth in reasonable detail the calculation of the amount of such
Loss in accordance with the provisions  hereof, and accompanied by copies of all
relevant documents and records. The omission to give such notice or provide such
certificate by the Indemnified Parties shall not relieve Indemnifying Parties of
their  obligation  under this Section except to the extent such omission results
in a failure  of actual  notice to the  Indemnifying  Parties  and  Indemnifying
Parties  are damaged  solely by such  failure to give  notice.  No Loss shall be

Agreement  up to that number of shares  that would have a fair  market  value of

amount equal to) $1,500,000.  The  indemnification  by the Stockholder shall not
apply (i) unless the Losses arose from an  inaccuracy in or breach of any of the

further  force  and  effect  upon  the   termination  of  the   representations,
warranties, indemnities and covenants as set forth in Section 11.1.

                  12.13 FURTHER ASSURANCES. Each party agrees to cooperate fully
with each other party and to execute such  further  instruments,  documents  and
agreements  and to give such further  written  assurances  as may be  reasonably
requested by any other party to evidence and reflect the transactions  described
herein and contemplated hereby and to carry into effect the intents and purposes
of this Agreement.

                  12.14 ABSENCE OF THIRD PARTY BENEFICIARY RIGHTS. No provisions
of this Agreement are intended,  nor shall be interpreted,  to provide or create
any  third  party  beneficiary  rights  or any  other  rights of any kind in any
client,  customer,  affiliate,  stockholder,  partner or  employee  of any party
hereto or any other  person or entity  unless  specifically  provided  otherwise
herein,  and,  except as so  provided,  all  provisions  hereof will be personal
solely between the parties to this Agreement.

                  12.15  PUBLIC  ANNOUNCEMENT.  TTI will  not  issue  any  press
release or make any other  public  disclosure  regarding  the  matters set forth
herein  without the prior express  written  approval of Palomar,  which approval
shall not be unreasonably  withheld.  Palomar may issue such press releases, and
make such other disclosures  regarding the Merger, as it determines are required
under applicable  securities laws or NASD rules after  reasonable  consultation,
where possible,  with TTI. Palomar and TTI will take all reasonable  precautions
to prevent  any trading in the  securities  of Palomar by  officers,  directors,
employees and agents of Palomar or TTI, as the case may be: (a) having knowledge
of any material  information  regarding Palomar or TTI provided  hereunder until
the  information in question has been publicly  disclosed;  or (b) to the extent
that such  trading  would  adversely  affect  the  treatment  of the Merger as a
"pooling of interests" for accounting purposes.

                  12.16 INTEGRATION. This Agreement, together with all Schedules
and Exhibits, constitutes the entire agreement among the parties relating to the
subject matter hereof and supersedes all prior agreements or  understandings  of
the parties  relating  thereto,  including  without  limitation a Memorandum  of
Understanding dated February 9, 1996.

                  12.17  CONFIDENTIALITY.  The  parties  hereto  agree  that all
information, whether written or oral, concerning the other party, its customers,
personnel,  products,  financial performance or business, disclosed to the other
party  or  its  representatives  in  the  course  of  meetings,   conversations,
negotiations or due diligence investigations in connection with the transactions
contemplated by this Agreement that is marked or identified as "confidential" or
which might permit the disclosing  party to obtain a competitive  advantage over
those  who do not have  access  thereto  ("Confidential  Information"),  and the
specific  financial  terms and  conditions of this  Agreement,  shall be held in
confidence  by the receiving  party and not used by the  receiving  party or its
representatives,  except as  contemplated  by this  Agreement.  Each party shall
exercise the same standard of care to protect any  Confidential  Information  of
the other party disclosed under this Section 12.17 as it uses to protect its own
confidential information.  Confidential Information does not include information
which (a) is or becomes a part of the public  domain  through no act or omission
of the receiving party, (b) was in the receiving party's lawful possession prior
to the  disclosure  and had not been  obtained  by the  receiving  party  either
directly or indirectly  from the disclosing  party or unlawfully  from any third
party, (c) is lawfully disclosed to the receiving party by a third party without
restriction on disclosure;  or (d) is  independently  developed by the receiving
party.

                  12.18  OBSERVER  RIGHTS.  For so  long as the  Stockholder  is
obligated to indemnify  Palomar in accordance  with Section 6 of this Agreement,
the  Stockholder  shall be  permitted  to attend  each  meeting  of the Board of
Directors of Palomar and to participate in all discussions  during such meeting.
Palomar shall send to the Stockholder  notice of the time and place of each such
meeting in the same  manner and at the same time as it shall send such notice to
its directors.  In the event that the  Stockholder can not attend any meeting of
the Board of Directors  that he is permitted to attend  pursuant to this Section
12.18,  the Stockholder may designate a person to attend in his place,  provided
that the attendance of such person is approved in advance by the Chairman of the
Board of Palomar, in his sole discretion.

                  12.19 ARBITRATION.  In the event the parties hereto are unable
to resolve any dispute with respect to claims arising  hereunder  within 30 days
of written notice of such dispute by one party to the others, such dispute shall
be settled by compulsory and binding arbitration by a panel of three arbitrators
in accordance with the Commercial  Arbitration Rules of the American Arbitration
Association,  and judgment  upon the award  rendered by the  arbitrators  may be
entered  in  any  court  having  jurisdiction.   The  parties  agree  that  such
arbitration shall be held in Boston, Massachusetts.

         Re:      Palomar/Tissue Merger -- Waiver of Indemnification

Dear Mario:

         In order to insure  that the  merger of Palomar  Medical  Technologies,
Inc.'s ("Palomar's")  wholly-owned subsidiary TTI Acquisition Corp. ("Sub") with
and into Tissue Technologies, Inc. ("TTI") pursuant to the Agreement and Plan of
Reorganization among Palomar, TTI, Sub and you (the "Stockholder"),  dated March
9, 1996 (the  "Merger  Agreement"),  is treated  for  accounting  purposes  as a
pooling of interests, Palomar hereby waives its right to receive indemnification
from TTI or Stockholder in accordance with Section 6 of the Merger  Agreement to
the extent that Palomar's auditors shall determine that any such indemnification
shall be  inconsistent  with the  treatment of the  transaction  as a pooling of
interests.

                                             Sincerely,

                                             /s/ Steve Georgiev

                           a. each share of the common stock, $.01 par value per
share, of Sub ("Sub Common Stock"),  issued and outstanding immediately prior to
the Effective Time of the Merger shall,  by virtue of the Merger and without any
action on the part of the holder thereof, be converted into and become one fully
paid and  non-assessable  share of common stock,  no par value per share, of TTI
("TTI Common Stock");

                           b.  each  share  of  TTI  Common   Stock  issued  and
outstanding  immediately prior to the Effective Time of the Merger, by virtue of
the Merger and  without

                                      -2-


any action on the part of the holder thereof,  shall be converted into the right
to receive  1.232577  shares of the common stock,  $.01 par value per share,  of
Palomar ("Palomar Common Stock"); and

                           c.  each  share  of  TTI  Common  Stock  held  in the
treasury of TTI prior to the Effective Time of the Merger shall be cancelled.

                  2.  From and  after  the  Effective  Time of the  Merger,  the

         E. Surrender and Exchange of Certificates Representing TTI Common Stock

         F.  Certain  Effects of the  Merger.  The  separate  existence  and the
corporate  organization  of Sub shall cease at the Effective  Time of the Merger

rights, privileges, immunities and powers and shall be subject to all the duties
and  liabilities of a corporation  organized  under chapter 1 of Title 10 of the
Arizona General  Corporation Law; and the Surviving  Corporation shall thereupon
and thereafter possess all the rights, privileges, immunities and franchises, of
a  public  as well as of a  private  nature,  of  each of Sub and  TTI;  and all
property,  real,  personal  and mixed,  and all debts due on  whatever  account,
including  subscriptions to shares,  and all other choses in action, and all and
every other  interest of or belonging to or due to each of Sub and TTI, shall be
taken and deemed to be  transferred  to and vested in the Surviving  Corporation
without  further act or deed; and the title to any real estate,  or any interest
therein,  vested  in Sub or TTI shall not  revert or be in any way  impaired  by
reason  of the  Merger;  and the  Surviving  Corporation  shall  thenceforth  be
responsible  and liable for all the  liabilities  and obligations of each of Sub
and TTI; and any claim  existing or action or  proceeding  pending by or against
Sub or TTI may be  prosecuted  as if such  Merger had not taken  place,  or such
Surviving  Corporation  may be substituted  in its place.  Neither the rights of
creditors nor any liens upon the property of Sub or TTI shall be impaired by the
Merger.

                                      -3-


         IN WITNESS WHEREOF,  each of Palomar,  Sub and TTI has caused this Plan
of Merger to be executed as of the date first written above.
