sheet that satisfies the requirements of Rule 434 of the Rules and Regulations.

         b. The Commission has not issued any order preventing or suspending the
use of any Preliminary  Prospectus.  When any  Preliminary  Prospectus was filed

requirements  of the Act and the Rules and  Regulations  and did not 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
light of the  circumstances  under which they were made, not misleading.  On the
Effective  Date, the date the Term Sheet,  if utilized,  is first filed with the

amendment or  supplement  did or will contain an untrue  statement of a material

         c. The Company is, and each of BTRL  Contracts and  Services,  Inc. and
BBI   North   American   Clinical   Laboratories,   Inc.   (collectively,    the

Date will be, duly  organized,  validly  existing and in good standing under the
laws of the  Commonwealth  of  Massachusetts.  The Company and the  Subsidiaries
have, and at the Closing Date and, if later,  the Option Closing Date will have,
full power and authority to conduct all the activities conducted by them, to own

business as described in the  Registration  Statement  and the  Prospectus.  The
Company is, and the Subsidiaries are, and at the Closing Date and, if later, the
Option  Closing Date they will be, duly licensed or qualified to do business and
in good  standing  as foreign  corporations  in all  jurisdictions  in which the
nature of the activities  conducted by them or the character of the assets owned
or leased by them makes such license or qualification  necessary,  except to the
extent  that the failure to be so  qualified  or be in good  standing  would not
materially  and adversely  affect the Company and its  Subsidiaries,  taken as a
whole, their business,  properties,  business prospects, condition (financial or
otherwise) net worth or results of  operations.  The  Subsidiaries  are the only
subsidiaries (as defined in the Act) of the Company.  Except as set forth in the

Date  and,  if  later,  the  Option  Closing  Date  will  not own,  directly  or

association  or other  entity and (ii) are not,  and at the Closing Date and, if

party  to any  agreement  or  understanding,  written  or  oral,  regarding  the
acquisition of an interest in any corporation, firm, partnership, joint venture,
association or other entity where such discussions, agreements or understandings
would require  amendment to the  Registration  Statement  pursuant to applicable
securities laws.  Complete and correct copies of the articles of  incorporation,
the bylaws or other organizational documents of the Company and the Subsidiaries
and all amendments  thereto have been delivered to the  Representatives,  and no
changes  therein will be made subsequent to the date hereof and prior to Closing

         d. The Company has authorized,  issued and outstanding capital stock as
set forth  under the  caption  "Capitalization"  in the  Prospectus.  All of the
outstanding shares of capital stock of the Company have been duly authorized and
validly issued, are fully paid and nonassessable, were issued in compliance with
all applicable  state and federal  securities laws, were not issued in violation
of or subject  to any  preemptive  rights or other  rights to  subscribe  for or
purchase  securities,  and conform to the description  thereof  contained in the
Prospectus; the Shares have been duly authorized and when issued and paid for as
contemplated herein will be validly issued, fully paid and nonassessable and the
Shares will conform to the description thereof contained in the Prospectus;  the
shares  of  Common  Stock  issuable  by the  Company  upon the  exercise  of the
Representatives'  Warrants have been duly authorized,  and, when issued and paid
for in  accordance  with the  terms of the  Representatives'  Warrants,  will be
validly issued, fully paid and nonassessable;  and no preemptive rights or other
rights to subscribe for or purchase  exist with respect to the issuance and sale
of the Shares or with respect to the Common Stock  issuable upon the exercise of
the Representatives'  Warrants. The Company has reserved and will keep available
for the exercise of the Representatives'  Warrants such number of authorized but
unissued  shares  of  Common  Stock  to  permit  the  exercise  in  full  of the
Representatives'  Warrants.  The description of the capital stock of the Company
in the  Registration  Statement and the  Prospectus  is, and at the Closing Date

herein. The Company owns of record and beneficially, free and clear of any lien,
adverse claim, security interest, equity or other encumbrance, the capital stock

issued by or related to the Subsidiaries.

         e. The financial  statements and schedules included in the Registration
Statement  or  the  Prospectus   comply  in  all  material   respects  with  the
requirements  of the Act and the Rules and  Regulations,  and present fairly the
financial  condition of the Company and the  Subsidiaries  as of the  respective
dates thereof and the results of operations, changes in shareholders' equity and
cash flows of the Company for the respective  periods  covered  thereby,  all in
conformity with generally accepted accounting principles applied on a consistent
basis  throughout the entire period involved.  No other financial  statements or
schedules of the Company are required by the Act or the Rules and Regulations to
be included in the Registration  Statement or the Prospectus.  Coopers & Lybrand
L.L.P.,  who have  reported on such  financial  statements  and  schedules,  are
independent  accountants  with respect to the Company as required by the Act and

Common  Stock  granted  pursuant to the  Company's  stock  option plans from the
reserves as described in the Registration Statement,  which shares received upon
exercise  will be subject to the lock-up  agreements  described  in Section 5(i)
below),  or  any  material  adverse  change,  or  any  development  which  could
reasonably be expected to involve a prospective  material adverse change, in the
business,  properties,  business prospects,  condition (financial or otherwise),
net worth or results of operations of the Company and the Subsidiaries, taken as
a  whole,  arising  for  any  reason  whatsoever,   (ii)  the  Company  and  the
Subsidiaries, taken as a whole, have not incurred nor will they incur, except in
the ordinary  course of business as described  in the  Prospectus,  any material
liabilities or obligations, direct or contingent, nor have they entered into nor
will they enter into,  except in the ordinary course of business as described in
the Prospectus,  any material transactions other than pursuant to this Agreement
and the transactions  referred to herein, and (iii) the Company has not and will
not have paid or declared any  dividends or other  distributions  of any kind on
any class of its capital stock.

or "promoter" or "principal  underwriter" for, an "investment  company," as such
terms are defined in the Investment Company Act of 1940, as amended.

         h.  There  are no  actions,  suits or  proceedings  pending  or, to the
knowledge of the  Company,  threatened  against or affecting  the Company or any
Subsidiary,  or any of their  officers in their  capacity as such, nor any basis
therefor, before or by any federal or state court, commission,  regulatory body,
administrative  agency or other governmental body, domestic or foreign,  wherein
an unfavorable ruling, decision or finding would materially and adversely affect
the  Company  and the  Subsidiaries,  taken  as a whole,  or  their  respective,
business,  properties,  business prospects,  condition (financial or otherwise),
net  worth  or  results  of  operations.  Neither  the  Company  nor  any of the
Subsidiaries is involved in any strike, job action or labor dispute,  and to the
Company's best knowledge no such action or dispute is threatened.

         i. The Company and the Subsidiaries  have, and at the Closing Date and,
if later,  the Option  Closing Date will have,  performed all their  obligations
required to be  performed  by them as of such date,  and neither the Company nor
any  Subsidiary  is, and at the Closing Date nor, if later,  the Option  Closing
Date will be, nor with the passage of time or the giving of notice or both would

debenture,  credit  agreement or any other evidence of indebtedness to which any
of them a party or by which their property is bound or affected, which violation

Subsidiaries,  taken  as  a  whole,  or  their  business,  properties,  business
prospects,   condition  (financial  or  otherwise),  net  worth  or  results  of
operations.  To the Company's best knowledge,  no other party under any contract
or other  instrument to which the Company or its  Subsidiaries are a party is in
default in any respect thereunder, which default would materially and


                                      -9-

                                                      


adversely  affect the Company and the  Subsidiaries,  taken as a whole, or their
business,  properties,  business prospects,  condition (financial or otherwise),
net worth or results of operations.  The Company and the  Subsidiaries  are not,
and at the Closing Date and, if later,  the Option  Closing Date will not be, in
violation of any provision of their respective articles of incorporation, bylaws
or other organizational documents.

         j. No consent,  approval,  authorization  or order of, or any filing or
declaration  with, any court or governmental  agency or body is required for the
issuance  and  sale of the  Shares  and  the  Representatives'  Warrants  by the
Company,  the  execution,  delivery  or  performance  of the  Agreement  and the
Representatives'  Warrants by the Company or the  consummation by the Company of
the  transactions on its part  contemplated  herein and in the  Representatives'
Warrants,  except  such as have  been  obtained  under  the Act or the Rules and
Regulations and such as may be required under state  securities or Blue Sky laws
or the bylaws and rules of the National Association of Securities Dealers,  Inc.
(the  "NASD")  in  connection   with  the  purchase  and   distribution  by  the
Underwriters of the Shares.

         k. The Company has full  corporate  power and  authority  to enter into
this Agreement and the Representatives'  Warrants,  to issue and sell the Shares
and the  Representatives'  Warrants  and to perform its  respective  obligations
thereunder.  The execution,  delivery and  performance of this Agreement and the
Representatives'  Warrants has been duly and validly  authorized by the Company,
and each of this  Agreement  and the  Representatives'  Warrants  has been  duly

agreement of the Company, enforceable against the Company in accordance with its
terms. The performance of this Agreement and the  Representatives'  Warrants and
the consummation of the transactions  contemplated  hereby and thereby will not,
with or without notice, the passage of time or both, result in the imposition of
any lien,  charge or  encumbrance  upon any of the assets of the  Company or any
Subsidiary  pursuant  to the  terms or  provisions  of, or result in a breach or
violation of any of the terms or provisions  of, or constitute a default  under,
or give any party a right to terminate any of its  obligations  under, or result

Subsidiary  or any of their  properties  is bound or  affected,  or  violate  or
conflict with any judgment,  ruling,  decree, order, statute, rule or regulation
of any court or other governmental  agency or body applicable to the business or
properties of the Company and any Subsidiary,  presently in effect,  a breach or
violation  of  which,  a  default  under  which,  a  termination  of  which,  an
acceleration  under  which,  or a  conflict  with  which  would  materially  and
adversely  affect the Company and any  Subsidiary,  taken as a whole,  and their
business,  properties,  business prospects,  condition (financial or otherwise),
net worth or results of operations.

         l. The Company and the  Subsidiaries  have good and marketable title to
all properties and assets described in the Prospectus as owned by them, free and
clear of all liens,  charges,  encumbrances or restrictions,  except such liens,
charges,  encumbrances  or  restrictions  as are described in the Prospectus and
those which,  individually  and in the aggregate,  are not material in amount or
which,  individually and in the aggregate,  do not adversely affect the use made
or  proposed  to be made of such  properties  and assets by the  Company and the
Subsidiaries.  The  Company  and  the  Subsidiaries,  as  lessees,  have  valid,
subsisting and enforceable leases for the properties described in the Prospectus
as leased by them.  The  agreements to which the Company or any Subsidiary are a
party  described in the  Prospectus  are valid  agreements,  enforceable  by the
Company or any Subsidiary (as applicable), except as the enforcement thereof may
be limited by  bankruptcy  and laws  relating  to the  rights  and  remedies  of
creditors  generally or by the availability of general equitable  remedies.  The
Company any the  Subsidiaries  own or lease all such properties as are necessary
to their operations as now conducted or as proposed to be conducted.

         m. There is no  document  or  contract  of a  character  required to be
described in the  Registration  Statement or the Prospectus or to be filed as an
exhibit  to the  Registration  Statement  which  is not  described  or  filed as
required.  All such  contracts to which the Company or any Subsidiary is a party
have  been  duly  authorized,  executed  and  delivered  by the  Company  or the
Subsidiary,  constitute  valid and  binding  agreements  of the  Company  or the
Subsidiary and are enforceable  against the Company or the Subsidiary and by the
Company or the Subsidiary  against the other parties  thereto in accordance with
the terms  thereof,  except as to (i) bankruptcy and laws relating to the rights
and  remedies of  creditors  generally  and (ii) the  availability  of equitable
remedies.

         n. No  statement,  representation,  warranty  or  covenant  made by the
Company in this  Agreement or made in any  certificate  or document  required by
Section 5 of this Agreement to be delivered to the  Underwriters was or will be,
when made, inaccurate, untrue or incorrect.

         o.  Neither  the  Company  nor  any  of  its  directors,   officers  or
controlling persons has taken,  directly or indirectly,  any action designed, or
which  might  reasonably  be  expected,  to cause or  result,  under  the Act or
otherwise,  in, or which has  constituted,  stabilization or manipulation of the
price of any  security  of the Company to  facilitate  the sale or resale of the
Shares.

         p.  No  holder  of   securities  of  the  Company  has  rights  to  the
registration  of any  securities  of the  Company  because  of the filing of the
Registration Statement or consummation of the transactions  contemplated by this
Agreement  which rights have not been validly  waived by the holder or otherwise
satisfied as of the date hereof. Except as disclosed in the Prospectus under the
caption  "Shares  Eligible For Future  Sale," no person has the right to require
registration  under  the Act of any  Common  Stock  or other  securities  of the
Company.

         q. The  Common  Stock is listed  and duly  admitted  to  trading on the
Nasdaq  National  Market (the  "NASDAQ  NATIONAL  MARKET"),  and the Company has
received  notification  that the quotation by the Nasdaq  National Market of the
Shares has been approved, subject to official notice of issuance of the Shares.

         r. (i) The Company  and the  Subsidiaries,  taken as a whole,  have all
trademarks,  trade names,  patent rights,  copyrights,  licenses,  approvals and
governmental   authorizations   necessary  to  conduct  their  business  as  now
conducted,  except  where the  failure to have any such  right  would not have a
material  and adverse  effect on the Company  and the  Subsidiaries,  taken as a
whole, or their respective business,  properties,  business prospects, condition
(financial or otherwise),  net worth or results of operations;  (ii) the Company
and the Subsidiaries  are not infringing any copyrights,  trade secrets or other
similar rights,  trademarks,  trade name rights or patent rights of others where
such  infringement  would have a material and adverse  effect on the Company and
the Subsidiaries,  taken as a whole, or their respective  business,  properties,
business prospects,  condition (financial or otherwise), net worth or results of
operations;  and (iii) no claim  has been made  against  the  Company  regarding
trademark,  trade  name,  patent,  copyright,  license,  trade  secret  or other
infringement  which would have a


                                      -12-

                                                      


material  and adverse  effect on the Company  and the  Subsidiaries,  taken as a
whole, or their respective business,  properties,  business prospects, condition
(financial or otherwise), net worth or results of operations.

         s. The Company has filed all federal,  state,  local and foreign income
tax returns which have been required to be filed, which returns are complete and
correct  in all  material  respects,  and has paid  all  taxes  and  assessments
received by it to the extent that such taxes or assessments have become due. All
payroll  withholdings  required to be made by the Company or any Subsidiary with
respect to employees have been made.  The charges,  accruals and reserves on the
books of the Company and the  Subsidiaries  in respect of any tax  liability for
any years  not  finally  determined  are  adequate  to meet any  assessments  or
reassessments  for additional taxes. The Company has no tax deficiency which has
been or might be asserted or  threatened  against the Company which could have a
material and adverse effect on the Company or its business, properties, business
prospects,   condition  (financial  or  otherwise),  net  worth  or  results  of
operations.

         t. The Company and its Subsidiaries own or possess all  authorizations,
approvals,  orders,  licenses,  registrations,  certificates  and permits of and
from,  and  have  made all  declarations  and  filings  with,  all  governmental
regulatory   officials  and  bodies  necessary  to  conduct  their  business  as
contemplated in the  Prospectus,  except where the failure to own or possess all
such authorizations,  approvals, orders, licenses,  registrations,  certificates
and permits or make such declarations and filings would not,  individually or in
the aggregate, materially and adversely affect the Company and the Subsidiaries,
taken as a whole, or their respective business, properties,  business prospects,
condition (financial or otherwise), net worth or results of operations. There is
no proceeding  pending or, to the knowledge of the Company,  threatened,  or any
basis  therefor  known  to the  Company,  which  may  cause  or  allow  any such
authorization,  approval, order, license, registration, certificate or permit to
be  revoked,  withdrawn,  canceled,  suspended  or not  renewed or result in any
material  impairment  of  the  rights  thereunder;   and  the  Company  and  its
Subsidiaries  are conducting  their business in compliance with all laws,  rules
and  regulations  applicable  thereto,  except  where any such failure to comply
would not have a material  adverse  effect on the Company and the  Subsidiaries,
taken as a whole, or their respective business, properties,  business prospects,
condition (financial or otherwise),  net worth or results of operations.  Except
as described in the  Registration  Statement  and the  Prospectus,  none of such
authorizations,  approvals,  orders,  licenses,  registrations,  certificates or
permits


                                      -13-

                                                      


contains any  restriction  that is materially  burdensome to the Company and the
Subsidiaries, taken as a whole.

         u. The Company and the Subsidiaries maintain insurance of the types and
in  the  amounts  generally  deemed  adequate  for  their  respective  business,
including,  but not limited to,  insurance  covering real and personal  property
owned or leased by the  Company  and the  Subsidiaries  against  theft,  damage,
destruction,  acts of vandalism and all other risks customarily insured against,
all of  which  insurance  is in full  force  and  effect.  The  Company  and the
Subsidiaries  are in compliance  with the terms of such policies in all material
respects.  The Company and the Subsidiaries  have not been refused any insurance
coverage sought or applied for; and the Company has no reason to believe that it
and the Subsidiaries will not be able to renew their existing insurance coverage
as and when such  coverage  expires or to obtain  similar  coverage from similar
insurers as may be necessary to continue their business at a cost that would not
have a material adverse effect on the Company and the  Subsidiaries,  taken as a
whole, or their business,  properties,  business prospects, condition (financial
or otherwise), net worth or results of operations.  There are no material claims
by the Company or any of the Subsidiaries  under any such policy as to which any
insurance  company is denying  liability or  defending  under a  reservation  of
rights clause.

         v. The Company and the  Subsidiaries are (i) in compliance with any and
all applicable foreign,  federal,  state and local laws and regulations relating
to the  protection of human health and safety,  the  environment or hazardous or
toxic substances or wastes,  pollutants or contaminants  ("ENVIRONMENTAL LAWS"),
(ii) have  received all permits,  licenses or other  approvals  required of them
under applicable  Environmental  Laws to conduct their  respective  business and
(iii)  are in  compliance  with all  terms and  conditions  of any such  permit,
license or approval,  except where such noncompliance  with Environmental  Laws,
failure to receive required  permits,  licenses or other approvals or failure to
comply with the terms and  conditions  of such  permits,  licenses or  approvals
would not,  singly or in the  aggregate,  have a material  adverse effect on the
Company and the  Subsidiaries,  taken as a whole, or their respective  business,
properties, business prospects, condition (financial or otherwise), net worth or
results of operations.

         w. In the  ordinary  course of its  business,  the  Company  conducts a
periodic review of the effect of Environmental Laws on the business,  operations
and  properties  of the Company and the  Subsidiaries  in the course of which it



                                      -14-

                                                      


identifies and evaluates  associated costs and liabilities  (including,  without
limitation, any capital or operating expenditures required for clean-up, closure
of properties or compliance with  Environmental  Laws or any permit,  license or
approval,  any related  constraints  on operating  activities  and any potential
liabilities  to third  parties).  On the basis of such  review,  the Company has
reasonably  concluded  that such  associated  costs and  liabilities  would not,
singly or in the  aggregate,  have a material  adverse effect on the Company and
the Subsidiaries,  taken as a whole, or their respective  business,  properties,
business prospects,  condition (financial or otherwise), net worth or results of
operations.

         x.  Neither  the  Company  nor any  Subsidiary  nor,  to the  Company's
knowledge,  any employee or agent of the Company or any  Subsidiary,  has at any
time  during  the last five  years  (i) made any  unlawful  contribution  to any
candidate for foreign  office,  or failed to disclose fully any  contribution in
violation of law, or (ii) made any payment to any federal or state  governmental
officer or official, or other person charged with similar public or quasi-public
duties,  other than  payments  required or  permitted  by the laws of the United
States or any jurisdiction thereof.

         y. The Company has not distributed  and, prior to the later to occur of
(i) the Closing Date or (ii) completion of the distribution of the Shares,  will
not  distribute  without  the prior  written  consent  of the  Underwriters  any
offering  material in connection  with the offering and sale of the Shares other
than the Registration Statement,  any Preliminary Prospectus,  the Prospectus or
other materials, if any, permitted by the Act and the Rules and Regulations. The
Company is not  involved  in any labor  dispute  and,  to the  knowledge  of the
Company, no such dispute is threatened.

         z. Neither the Company nor its officers, directors, employees or agents
have taken or will take,  directly  or  indirectly,  (i) any action  designed to
cause or to result in, or that has  constituted  or which  might  reasonably  be
expected to constitute,  the  stabilization  or manipulation of the price of any
security of the Company to facilitate the sale or resale of the Shares,  or (ii)
since the filing of the  Registration  Statement,  except in connection with the
sale of the Shares, (A) sold, bid for, purchased, attempted to induce any person
to purchase, or paid anyone any compensation for soliciting the purchase of, the
Shares or (B) paid or agreed to pay any person any  compensation  for soliciting
another to purchase any other securities of the Company.



                                      -15-

                                                      


         aa.  The Company has obtained from each of its  directors, officers and
the other  shareholders  specified by the  Representatives  a written  agreement
that,  for a period of 180 days from the date of the  Prospectus,  he, she or it
will not,  without  the prior  written  consent  of Oscar  Gruss,  offer,  sell,
contract  to sell,  grant any option for the sale of, or  otherwise  dispose of,
directly or indirectly,  any shares of Common Stock or any security  convertible
into,  or  exchangeable  or  exercisable  for,  shares of Common  Stock or other
securities of the Company.

         bb. The Company has complied with all  provisions of Florida  Statutes,
ss. 517.075, relating to issuers doing business with Cuba.

         cc. The Company has no liability or obligation of any nature (absolute,
accrued,  contingent  or otherwise)  which is not fully  reflected or adequately
reserved  against in the balance sheet at June 30, 1996,  except for liabilities
(i) incurred in the ordinary course of business and not required under generally
accepted  accounting  procedures  to be  reflected  on the balance  sheet,  (ii)
incurred  since June 30, 1996 in the ordinary  course of business and consistent
with past practice, or (iii) described in the Prospectus.  The Company maintains
a system of  internal  accounting  controls  sufficient  to  provide  reasonable
assurance that (A)  transactions  are executed in accordance  with  management's
general or specific  authorizations;  (B) transactions are recorded as necessary
to permit  preparation  of financial  statements  in conformity  with  generally
accepted accounting principles and to maintain accounting for assets; (C) access
to assets is permitted only in accordance with management's  general or specific
authorization;  (D) the recorded  accountability for assets is compared with the
existing  assets at reasonable  intervals and  appropriate  action is taken with
respect to any  differences and (E) reserves for obsolete  inventory,  bad debts
and sales returns and allowances are adequate.

         Any  certificate  signed by an officer of the Company and  delivered to
the Underwriters or counsel for the Underwriters at a closing hereunder shall be
deemed a  representation  and warranty of the Company to each  Underwriter as to
the matters covered thereby as of the date thereof.

4.       AGREEMENTS OF THE COMPANY

         The Company agrees with the several Underwriters as follows:


                                      -16-


                                                      


         a.  The  Company  will  not,  either  prior  to the  Effective  Date or
thereafter  during  such  period  as the  Prospectus  is  required  by law to be
delivered in connection  with sales of the Shares by an  Underwriter  or dealer,
file  any  amendment  or  supplement  to  the  Registration   Statement  or  the
Prospectus,  unless a copy  thereof  shall  first  have  been  submitted  to the
Underwriters  within a reasonable period of time prior to the filing thereof and
the Underwriters shall not have objected thereto in good faith.

         b. The  Company  will use its best  efforts  to cause the  Registration
Statement to become effective, and will notify the Underwriters and will confirm
such advice in writing, (i) when the Registration Statement has become effective
and when any  post-effective  amendment thereto becomes  effective,  (ii) of any
request by the Commission  for  amendments or  supplements  to the  Registration
Statement or the Prospectus or for additional information, (iii) of the issuance
by  the  Commission  of any  stop  order  suspending  the  effectiveness  of the
Registration  Statement or the initiation of any proceedings for that purpose or
the  threat  thereof,  (iv) of the  happening  of any event  during  the  period
mentioned in the third sentence of Section 4(e) that makes any statement made in
the Registration  Statement or the Prospectus untrue or that requires the making
of any changes in the Registration  Statement or the Prospectus in order to make
the statements therein not misleading,  and (v) of receipt by the Company or any
representative  or attorney of the Company of any other  communication  from the
Commission relating to the Company, the Registration Statement,  any preliminary
prospectus,  the Term  Sheet or the  Prospectus.  If at any time the  Commission
shall  issue  any  order  suspending  the   effectiveness  of  the  Registration
Statement,  the  Company  will  make  every  reasonable  effort  to  obtain  the
withdrawal  of such order at the earliest  possible  moment.  If the Company has
omitted any information from the Registration Statement pursuant to Rule 430A of
the Rules and Regulations,  the Company will use its best efforts to comply with
the provisions of, and make all requisite  filings with the Commission  pursuant
to,  said Rule 430A and,  if a Term  Sheet is used,  Rule 434 and to notify  the
Underwriters promptly of all such filings.

         c. The Company will furnish to the  Underwriters  without  charge three
signed copies of the Registration Statement and of any post-effective  amendment
thereto, including financial statements and schedules, and all exhibits thereto,
and will furnish to the Underwriters, without charge, for transmittal to each of
the other  Underwriters,  such number of  conformed  copies of the  Registration
Statement and


                                      -17-

                                                      


any  post-effective  amendment  thereto,   including  financial  statements  and
schedules, but without exhibits, as you may reasonably request.

         d. The Company will comply with all the provisions of any  undertakings
contained in the Registration Statement.

         e. On the Effective Date, and thereafter from time to time, the Company
will deliver to each of the Underwriters,  without charge, as many copies of the
Prospectus  or any amendment or supplement  thereto as the  Representatives  may
reasonably  request.  The Company  consents,  subject to the  provisions  of the
following sentence,  to the use of the Prospectus or any amendment or supplement
thereto by the several Underwriters and by all dealers to whom the Shares may be
sold,  both in  connection  with the  offering or sale of the Shares and for any
period of time  thereafter  during which the Prospectus is required by law to be
delivered in connection  therewith.  If during the nine-month period referred to
in Section  10(a)(3) of the Act any event  shall occur which in the  judgment of
the Company or counsel to the Underwriters should be set forth in the Prospectus
in order to make any  statement  therein,  in light of the  circumstances  under
which it was made, not misleading,  or if it is necessary to supplement or amend
the Prospectus to comply with law, the Company will  forthwith  prepare and duly
file with the Commission an  appropriate  supplement or amendment  thereto,  and
will deliver to each of the Underwriters,  without charge, such number of copies
of such  supplement or amendment to the  Prospectus as the  Representatives  may
reasonably  request  and,  in case any  Underwriter  is  required  to  deliver a
prospectus  after such nine month period,  the Company upon request,  but at the
expense of such Underwriter,  will promptly prepare such amendment or amendments
to the  Registration  Statement  and  Prospectus  as may be  necessary to permit
compliance with the requirements of Section 10(a)(3) of the Act.

         f.  Prior to any  public  offering  of the  Shares,  the  Company  will
cooperate with the  Underwriters  and counsel to the  Underwriters in connection
with the  registration or  qualification  of the Shares for offer and sale under
the securities or Blue Sky laws of such  jurisdictions  as the  Underwriters may
request;  provided that in no event shall the Company be obligated to qualify to
do business in any jurisdiction  where it is not now so qualified or to take any
action which would subject it to general service of process in any  jurisdiction
where it is not now so subject.



                                      -18-

                                                      


         g. During the period of five years  commencing on the  Effective  Date,
the Company will furnish to the Representatives,  and each other Underwriter who
may so request,  copies of such  financial  statements  and other  periodic  and
special reports as the Company may from time to time distribute generally to the
holders  of  any  class  of  its  capital   stock,   and  will  furnish  to  the
Representatives,  and each other Underwriter who may so request,  a copy of each
annual or other report it shall be required to file with the Commission.

         h.  The  Company  will  make  generally  available  to  holders  of its
securities as soon as may be practicable but in no event later than the last day
of the fifteenth full calendar month following the calendar quarter in which the
Effective Date falls, an earnings statement (which need not be audited but shall
be in reasonable detail) for the applicable  12-month period after the Effective
Date,  satisfying the provisions of Section 11(a) of the Act (including Rule 158
of the Rules and Regulations).

         i. Whether or not the  transactions  contemplated by this Agreement are
consummated or this Agreement is terminated,  the Company will pay, or reimburse
if paid by the Underwriters  all costs and expenses  incident to the performance
of the  obligations  of the  Company  under this  Agreement,  including  but not
limited to costs and  expenses of or relating to (i) the  preparation,  printing
and filing of the  Registration  Statement and exhibits to it, each  preliminary
prospectus,  Term Sheet,  Prospectus  and any  amendment  or  supplement  to the
Registration  Statement  or  Prospectus,  (ii) the  preparation  and delivery of
certificates  representing the Shares, (iii) the printing of this Agreement, the
Agreement  among  Underwriters,  any  Dealer  Agreements  and any  Underwriters'
Questionnaires,  (iv) furnishing  (including costs of shipping and mailing) such
copies of the  Registration  Statement,  the Prospectus,  the Term Sheet and any
preliminary  prospectus,  and all amendments and supplements  thereto, as may be
requested for use in connection  with the offering and sale of the Shares by the
Underwriters  or by dealers to whom  Shares may be sold,  (v) the listing of the
Shares on the Nasdaq National  Market,  (vi) any filings  required to be made by
the  Underwriters  with the NASD,  including the fees,  disbursements  and other
charges of counsel  for the  Underwriters  in  connection  therewith,  (vii) the
registration  or  qualification  of the  Shares  for  offer  and sale  under the
securities or Blue Sky laws of such jurisdictions designated pursuant to Section
4(f),  including  the fees,  disbursements  and other  charges of counsel to the
Underwriters  in  connection  therewith,  and the  preparation  and  printing of
preliminary,   supplemental   and  final  Blue  Sky   memoranda,   (viii)  fees,
disbursements



                                      -19-

                                                      


and other charges to the Company (but not those of counsel for the Underwriters,
except as otherwise  provided  herein),  (ix) the transfer agent for the Shares,
(x) informational  meetings and (xi) the "tombstone"  advertisement with respect
to the Shares.  In addition to the Company's  responsibility  for payment of the
foregoing expenses,  the Company shall pay to the Underwriters a non-accountable
expense  allowance equal to one percent (1%) of the gross proceeds from the sale
of the Shares (including in such amount the proceeds from any sale of the Option
Shares),  of  which  $40,000  has  been  paid to date.  If the  offering  is not
consummated,  the  Underwriters  will be  entitled to  reimbursement  for actual
out-of-pocket expenses, and will return to the Company any unused portion of the
$40,000. If the Offering is not consummated, the Underwriters will return to the
Company any unused portion of the pre-paid expense allowance.

         j. If this Agreement shall be terminated by the Company pursuant to any
of the provisions hereof (otherwise than pursuant to Section 8 hereof) or if for
any reason the Company shall be unable to perform its obligations hereunder, the
Company will reimburse the several Underwriters for all reasonable out-of-pocket
expenses (including the fees,  disbursements and other charges of counsel to the
Underwriters)  reasonably incurred by them in connection  herewith.  The Company
shall reimburse Oscar Gruss within five days of termination of this Agreement.

         k. The Company will not at any time,  directly or indirectly,  take any
action designed,  or which might reasonably be expected,  to cause or result in,
or which  will  constitute,  stabilization  of the price of the shares of Common
Stock to facilitate the sale or resale of any of the Shares.

         l. The Company will apply the net  proceeds  from the offering and sale
of the Shares in the manner set forth in the Prospectus under "Use of Proceeds,"
and shall file such reports with the Commission  with respect to the sale of the
Company Shares and the application of the proceeds  therefrom as may be required
in accordance with Rule 463 under the Act.

         m.  During  the  period of 180 days  commencing  at the  Closing  Date,
without the prior written consent of Oscar Gruss,  which consent may be withheld
in the sole discretion of Oscar Gruss and other than pursuant to the exercise of
outstanding  warrants and stock  options or otherwise  pursuant to the Company's
stock  option plan  disclosed  in the  Prospectus,  the Company  will not issue,
offer,  sell,  grant  options to  purchase  or  otherwise  dispose of any of the
Company's  equity



                                      -20-


                                                      


securities or any other  securities  convertible  into or exchangeable  with its

                                      -25-


                                                      


                  (xi)  the  statements  in  the  Prospectus   insofar  as  such
statements  constitute a summary of documents  referred to therein or matters of
law, fairly summarize in all material  respects the information  called for with
respect to such documents and matters of law;

                  (xii)  each  of  the  Company  and  each  Subsidiary  has  all
necessary approvals, orders, licenses,  registrations,  certificates and permits
of and from and have made all  declarations  and filings  with all  governmental
regulatory officials and bodies necessary to conduct their business as described
in the  Prospectus,  except  where the failure to have all such  authorizations,
approvals,  orders,  licenses,  registrations,  certificates and permits or make
such declarations or filings would not, individually or in the aggregate, have a
material  adverse  effect  on  the  business,  properties,  business  prospects,
condition  (financial or  otherwise),  net worth or results of operations of the
Company and the Subsidiaries taken as a whole.

                  (xiii) neither the Company nor any of the  Subsidiaries  is an

the meaning of the Investment Company Act of 1940, as amended.

                  (xiv)  to such  counsel's  knowledge,  there  are no  legal or
governmental  proceedings  pending  or  threatened  to which the  Company or any
Subsidiary  are a party or to which  any of the  properties  of the  Company  is
subject that are required to be described in the  Registration  Statement or the
Prospectus and are not so described;

                  (xv) to such counsel's  knowledge,  no holder of securities of
the  Company  has rights  which have not been  waived to require  the Company to

                  (xvi) such counsel does not know of any contracts or documents
required to be filed as exhibits to the  Registration  Statement or described in
the  Registration  Statement or  Prospectus  or any  supplements  or  amendments
thereto  which are  required to be filed and are not so filed as  required,  and
each  description  of  such  contracts  and  documents  as is  contained  in the
Registration  Statement and Prospectus  fairly presents in all material respects
the information required under the Act and the Rules and Regulations;


                                      -26-



                                                      

                  (xvii)  as  of  the  Effective  Date,  the  Shares  were  duly
authorized for quotation on the Nasdaq  National  Market upon official notice of
issuance.

         Such  counsel  shall also state that such counsel has  participated  in
conferences   with   representatives   of   the   Underwriters,   officers   and
representatives of the Company and representatives of the independent  certified
public  accountants  of the Company,  at which  conferences  the contents of the
Registration Statement and the Prospectus and related matters were discussed and
that,  although  such  counsel  is not  passing  upon and does  not  assume  any
responsibility  for the  accuracy,  completeness  or fairness of the  statements
contained in the Registration  Statement and the Prospectus (except as set forth
in Section  5(f)(xi)),  on the basis of the  foregoing,  nothing has come to the
attention of such counsel that leads them to believe that (except for  financial
statements,  schedules and financial information,  as to which such counsel need
not express any belief),  the  Registration  Statement  and the  Prospectus,  as
amended,  included  therein  at  the  time  the  Registration  Statement  became
effective  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  and  the   Prospectus,   as  amended  or
supplemented,  if applicable,  as of the date it was filed pursuant to the Rules
and  Regulations  and as of the Closing Date or the Option  Closing Date, as the
case may be,  contained  any untrue  statement of a material  fact or omitted to
state a material  fact  necessary in order to make the  statements  therein,  in
light of the circumstances under which they were made, not misleading.

         In rendering  the foregoing  opinions,  counsel may rely, to the extent
they  deem  such  reliance  proper,  on the  opinions  (in  form  and  substance
reasonably  satisfactory to Underwriters'  counsel) of other counsel  reasonably
acceptable  to  Underwriters'  counsel  as to  matters  governed  by the laws of
jurisdictions   other  than  the  United   States   and  the   Commonwealth   of
Massachusetts,  and as to matters of fact, upon  certificates of officers of the
Company and of government officials; provided that such counsel shall state that
the opinion of any other counsel is in form satisfactory to such counsel and, in
such  counsel's  opinion,  such counsel and the  Underwriters  are  justified in
relying on such  opinions  of other  counsel.  Copies of all such  opinions  and
certificates  shall be furnished to counsel to the  Underwriters  on the Closing
Date or the Option Closing Date, as the case may be.



                                      -27-


                                                      


         g. The  Underwriter  shall have received an opinion,  dated the Closing
Date  and,  with  respect  to  the  Option  Shares,  the  Option  Closing  Date,
satisfactory  in form and  substance  to the  Underwriters  and  counsel for the
Underwriters,  from  Buc and  Beardsley,  regulatory  counsel  for the  Company,
covering the following matters:

                  (i) Any statements set forth in the Registration Statement and
the  Prospectus  under  the  captions  "Risk  Factors  --  Stringent  Government
Regulation"  and "Business --  Government  Regulation"  (collectively,  the "FDA
PORTION")   constitute  an  accurate   summary  in  all  material   respects  of
restrictions applicable to the business of the Company arising under the Federal
Food, Drug, and Cosmetic Act (the "FFDCA") or the regulations  thereunder or the
FDA  regulation of the business or  operations  of the Company,  or of any legal
matters,  documents or proceedings referred to therein and relating to the FFDCA
or the FDA's  regulation  of the  business or  operations  of the Company or the
Company's compliance therewith.

                  (ii) To  counsel's  knowledge,  the Company has filed with the
FDA for and received approval of all applications,  licenses, registrations, and
permits ("REGULATORY  AUTHORIZATIONS")  necessary to conduct the business of the
Company described in the Registration Statement and the Prospectus.

                  (iii) Based upon a review of the FDA  Portion,  counsel has no
reason to  believe  that the  information  contained  in the FDA  Portion of the
Registration  Statement  and the  Prospectus  at the  time it  became  effective
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  or that on the Closing Date or the Option  Closing Date, as the
case may be, the  information  contained in the FDA Portion of the Prospectus or
any amendments or supplements to the FDA Portion of the Prospectus  contains any
untrue  statement  of a  material  fact or  omits  to state  any  material  fact
necessary in order to make the statements therein not misleading.

         h. The  Underwriters  shall have  received  from the  Company  the duly
executed Representatives' Warrants.

         i. The Underwriters  shall have received an opinion,  dated the Closing
Date and,  with respect to the Option  Shares,  the Option  Closing  Date,  from
Fulbright & Jaworski L.L.P.,  counsel to the  Underwriters,  with respect to the



                                      -28-

                                                      


Registration Statement,  the Prospectus and this Agreement,  which opinion shall
be satisfactory in all respects to the Underwriters.

         j.  The  Underwriters  shall  have  received,  on or  prior to the date
hereof, agreements from all directors,  officers and certain shareholders of the
Company in the form  attached as Exhibit B hereto  holding in the  aggregate  at
least ____ shares of Common Stock,  stating that each of such  persons,  without
the prior written  consent of Oscar Gruss,  will not offer to sell,  contract to
sell, sell,  distribute,  grant any option to purchase,  pledge,  hypothecate or
otherwise  dispose  of,  directly  or  indirectly,  any  Common  Stock,  or  any
securities  convertible  into or  exchangeable  for Common  Stock of the Company
(including,  without limitation,  Common Stock of the Company that may be deemed
to be  beneficially  owned by the  undersigned in accordance  with the rules and
regulations  of the Commission and Common Stock that may be issued upon exercise
of a stock option or warrant),  or rights to acquire  such Common  Stock,  for a
period of 180 days from the date hereof.

         k. At the  Effective  Date  and  concurrently  with the  execution  and
delivery of this Agreement, Coopers & Lybrand L.L.P. shall have furnished to the
Underwriters  a  letter,  dated  the  date  of its  delivery,  addressed  to the
Underwriters  and  in  form  and  substance  satisfactory  to  the  Underwriters
confirming that they are independent  accountants with respect to the Company as
required by the Act and the Rules and  Regulations  and with  respect to certain
financial  and other  statistical  and  numerical  information  contained in the
Registration  Statement.  At the Closing Date, and, as to the Option Shares, the
Option  Closing  Date,  Coopers & Lybrand  L.L.P.  shall have  furnished  to the
Underwriters a letter,  dated the date of its delivery,  which shall confirm, on
the basis of a review in accordance  with the procedures set forth in the letter
from each accountant, that nothing has come to their attention during the period
from  the  date of each  letter  referred  to in the  prior  sentence  to a date
(specified in each letter) not more than five days prior to the Closing Date and
the Option  Closing  Date, as the case may be, which would require any change in
their letter dated the date hereof if it were required to be dated and delivered
at the Closing Date and the Option Closing Date.

         l.  Concurrently  with the execution and delivery of this Agreement and
at the Closing Date and, with respect to the Option  Shares,  the Option Closing
Date, there shall be furnished to the Underwriters a certificate, dated the date
of its delivery,  signed by the Chief Executive  Officer and the Chief Financial
Officer of


                                      -29-

effect that:

                  (i) Each signer of such certificate has carefully examined the
Registration  Statement  and  the  Prospectus  and  (A) as of the  date  of such
certificate,  the  Registration  Statement and the Prospectus do not 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  not
misleading and (B) in the case of the certificate  delivered at the Closing Date
and the Option Closing Date, since the Effective Date no event has occurred as a
result of which it is necessary to amend or supplement  the  Prospectus in order
to make the statements therein not untrue or misleading in any material respect.

                  (ii) Each of the representations and warranties of the Company
contained in this Agreement  were,  when  originally  made, and are, at the time
such certificate is delivered, true and correct.

                  (iii) Each of the  covenants  required to be  performed by the
Company herein on or prior to the date of such certificate has been duly, timely
and fully  performed  and each  condition  herein  required to be  satisfied  or
fulfilled on or prior to the date of such certificate has been duly,  timely and
fully satisfied or fulfilled.

         m. The Shares shall be qualified for sale in such  jurisdictions as the
Underwriters  may,  pursuant  to the  provisions  of  Section  4(f),  reasonably
request,  and each such qualification  shall be in effect and not subject to any
stop order or other proceeding on the Closing Date or the Option Closing Date.

         n.  Prior  to the  Closing  Date,  the  Shares  shall  have  been  duly
authorized  for listing on the Nasdaq  National  Market upon official  notice of

                                      -30-

                                                      


of the conditions  concurrent and precedent to the obligations  hereunder of the
Underwriters.

6.       INDEMNIFICATION

         a. The Company will indemnify and hold harmless each  Underwriter,  the

if any, who controls,  within the meaning of Section 15 of the Act or Section 20
of the  Exchange  Act,  each  Underwriter,  from and against any and all losses,
claims, liabilities,  expenses and damages (including any and all investigative,
legal and other expenses  reasonably incurred in connection with, and any amount
paid in settlement of, any action,  suit or proceeding or any claim asserted) to
which they, or any of them,  may become  subject under the Act, the Exchange Act
or  other  Federal  or state  statutory  law or  regulation,  at  common  law or
otherwise, insofar as such losses, claims, liabilities,  expenses or damages (i)
arise out of or are based on any untrue statement or alleged untrue statement of
a material  fact  contained  in any  preliminary  prospectus,  the  Registration
Statement or the  Prospectus or any amendment or supplement to the  Registration
Statement or the  Prospectus,  or the  omission or alleged  omission to state in
such  document a material  fact required to be stated in it or necessary to make
the statements in it not misleading,  (ii) arise out of or are based in whole or
in part on any inaccuracy in the  representations  and warranties of the Company
contained  herein,  or (iii)  arise out of or are based upon any  failure of the
Company to perform its obligations hereunder or under law in connection with the
transactions  contemplated hereby;  provided that the Company will not be liable
to the extent that such loss,  claim,  liability,  expense or damage arises from
the sale of the Shares in the public  offering  to any person by an  Underwriter
and is based on an untrue  statement or omission or alleged untrue  statement or
omission made in reliance on and in conformity with information  relating to any
Underwriter  furnished in writing to the Company  expressly for inclusion in the
Registration  Statement,  the preliminary  prospectus or the Prospectus,  or any
amendment or supplement  thereto.  The Company  acknowledges that the statements
set forth in the first two paragraphs  under the heading  "Underwriting"  in the
preliminary  prospectus  and the  Prospectus  constitute  the  only  information
relating to any  Underwriter  furnished in writing to the Company  expressly for
inclusion in the  Registration  Statement,  the  preliminary  prospectus  or the
Prospectus. This indemnity will be in addition to any liability that the Company
might otherwise have.


                                      -31-

                                                      


         b. Each Underwriter will indemnify and hold harmless the Company,  each
director  of  the  Company  and  each  officer  of the  Company  who  signs  the
Registration Statement and each person, if any, who controls, within the meaning
of Section 15 of the Act or Section 20 of the Exchange Act, the Company,  to the
same extent as the foregoing indemnity from the Company to each Underwriter,  as
set forth in Section  6(a),  but only  insofar as losses,  claims,  liabilities,
expenses  or  damages  arise  out of or are  based on any  untrue  statement  or
omission or alleged  untrue  statement  or  omission  made in reliance on and in
conformity with information relating to any Underwriter  furnished in writing to
the Company  expressly for use in the  Registration  Statement,  the preliminary
prospectus  or the  Prospectus,  or any  amendment or  supplement  thereto.  The
Company  acknowledges  that the statements set forth in the first two paragraphs
under  the  heading   "Underwriting"  in  the  preliminary  prospectus  and  the
Prospectus constitute the only information relating to any Underwriter furnished
in writing to the Company by the  Underwriters  expressly  for  inclusion in the
Registration  Statement,  the  preliminary  prospectus or the  Prospectus.  This
indemnity  will be in  addition to any  liability  that each  Underwriter  might
otherwise have.

         c. Any party that proposes to assert the right to be indemnified  under
this Section 6 shall,  promptly after receipt of notice of  commencement  of any
action  against  such party in respect of which a claim is to be made against an
indemnifying   party  or  parties   under  this  Section  6,  notify  each  such
indemnifying party in writing of the commencement of such action, enclosing with
such  notice a copy of all papers  served,  but the  omission  so to notify such
indemnifying  party will not relieve it from any  liability  that it may have to
any indemnified  party under the foregoing  provisions of this Section 6 unless,
and only to the extent that,  such omission  results in the loss of  substantive
rights or  defenses  by the  indemnifying  party.  If any such action is brought
against any  indemnified  party and it notifies  the  indemnifying  party of its
commencement,  the indemnifying party will be entitled to participate in and, to
the extent that it elects by delivering  written notice to the indemnified party
promptly  after  receiving  notice of the  commencement  of the action  from the
indemnified party, jointly with any other indemnifying party similarly notified,
to assume the defense of the action, with counsel reasonably satisfactory to the
indemnified  party.  After notice from the indemnifying party to the indemnified
party of its election to assume the defense,  the indemnifying party will not be
liable  to the  indemnified  party  for any  legal or other  expenses  except as
provided below and except for the reasonable costs of investigation subsequently
incurred  by  the  indemnified  party  in  connection  with  the  defense.   The
indemnified


                                      -32-

                                                      


party will have the right to employ its own counsel in any such action,  but the
fees,  expenses and other charges of such counsel will be at the expense of such
indemnified  party unless (i) the employment of counsel by the indemnified party
has been authorized in writing by the indemnifying  party,  (ii) there are legal
defenses available to it or other indemnified parties that are different from or
in addition to those available to the indemnifying  party, (iii) the indemnified
party has  reasonably  concluded  that a conflict or potential  conflict  exists
(based on advice of counsel to the  indemnified  party) between the  indemnified
party and the indemnifying  party (in which case the indemnifying party will not
have the right to direct the defense of such action on behalf of the indemnified
party),  or (iv) the  indemnifying  party has not in fact  employed  counsel  to
assume the  defense of such  action  within a  reasonable  time after  receiving
notice of the commencement of the action,  in each of which cases the reasonable
fees,  disbursements  and other charges of counsel will be at the expense of the
indemnifying  party or parties.  It is understood that the indemnifying party or
parties shall not, in connection  with any proceeding or related  proceedings in
the same  jurisdiction,  be liable for the reasonable  fees,  disbursements  and
other  charges of more than one  separate  firm  admitted  to  practice  in such
jurisdiction at any one time for all such indemnified party or parties. All such
fees,  disbursements  and other charges will be  reimbursed by the  indemnifying
party promptly as they are incurred.  Any indemnifying  party will not be liable
for any settlement of any action or claim effected  without its written  consent
(which consent will not be unreasonably withheld or delayed).

         d.  In  order  to  provide  for  just  and  equitable  contribution  in
circumstances  in  which  the  indemnification  provided  for in  the  foregoing
paragraphs of this Section 6 is applicable in accordance with its terms, but for
any reason is held to be unavailable from the Company or the  Underwriters,  the
indemnifying  party will  contribute to the total losses,  claims,  liabilities,
expenses and damages  (including  any  investigative,  legal and other  expenses
reasonably  incurred in connection  with,  and any amount paid in settlement of,
any action,  suit or proceeding or any claim  asserted,  but after deducting any
contribution  received by the Company from persons other than the  Underwriters,
such as persons who control the Company within the meaning of the Act,  officers
of the  Company  who signed the  Registration  Statement  and  directors  of the
Company,  who also may be liable for  contribution) to which the Company and any
one or more of the  Underwriters  may be subject in such  proportion as shall be
appropriate  to reflect the  relative  benefits  received by the Company and the
Underwriters. The relative benefits received by the Company and the Underwriters
shall be deemed to be in the same  proportion


                                      -33-


                                                      


as the total net proceeds from the offering (before deducting expenses) received
by the  Company  bears  to the  total  underwriting  discounts  and  commissions
received  by the  Underwriters,  in each  case as set  forth in the table on the
cover page of the  Prospectus.  If, but only if, the allocation  provided by the
foregoing  sentence is not  permitted  by  applicable  law,  the  allocation  of
contribution  shall be made in such  proportion as is appropriate to reflect not
only the relative benefits referred to in the foregoing  sentence,  but also the
relative  fault  of  the  Company  and  the  Underwriters  with  respect  to the
statements or omissions which resulted in such loss, claim,  liability,  expense
or damage, or action in respect thereof, as well as any other relevant equitable
considerations  with  respect to such  offering.  Such  relative  fault shall be
determined by reference to whether the untrue or alleged  untrue  statement of a
material  fact or omission or alleged  omission to state a material fact relates
to information  supplied by the Company or the  Underwriters,  the intent of the
parties and their relative  knowledge,  access to information and opportunity to
correct or prevent such statement or omission.  The Company and the Underwriters
agree that it would not be just and equitable if contributions  pursuant to this
Section  6(d)  were  to be  determined  by  pro  rata  allocation  (even  if the
Underwriters were treated as one entity for such purpose) or by any other method
of  allocation  which does not take into  account the  equitable  considerations
referred  to herein.  The amount  paid or payable by an  indemnified  party as a
result of the loss,  claim,  liability,  expense or damage, or action in respect
thereof,  referred to above in this Section 6(d) shall be deemed to include, for
purpose of this Section 6(d), any legal or other expenses reasonably incurred by
such  indemnified  party in connection with  investigating or defending any such
action or  claim.  Notwithstanding  the  provisions  of this  Section  6(d),  no
Underwriter  shall be  required  to  contribute  any  amount  in  excess  of the
underwriting  discounts  received by it and no person found guilty of fraudulent
misrepresentation  (within  the  meaning  of  Section  11(f) of the Act) will be
entitled to  contribution  from any person who was not guilty of such fraudulent
misrepresentation.  The  Underwriters'  obligations to contribute as provided in
this Section 6(d) are several in  proportion  to their  respective  underwriting
obligations  and not joint.  For purposes of this Section  6(d),  any person who
controls a party to this  Agreement  within the meaning of the Act will have the
same rights to contribution  as that party,  and each officer of the Company who
signed the  Registration  Statement will have the same rights to contribution as
the Company,  subject in each case to the provisions  hereof. Any party entitled
to contribution,  promptly after receipt of notice of commencement of any action
against any such party in respect of which a claim for  contribution may be made
under this  Section  6(d),  will  notify  any such  party or


                                      -34-


                                                      


parties from whom  contribution  may be sought from any other  obligation  it or
they may have under this Section 6(d). No party will be liable for  contribution
with respect to any action or claim settled  without its written  consent (which
consent will not be unreasonably withheld or delayed).

         e. The indemnity and contribution  agreements contained in this Section
6 and the  representations  and  warranties  of the  Company  contained  in this
Agreement shall remain operative and in full force and effect  regardless of (i)
any investigation  made by or on behalf of the Underwriters,  (ii) acceptance of
any of the  Shares  and  payment  therefor,  or (iii)  any  termination  of this
Agreement

7.       REIMBURSEMENT OF CERTAIN EXPENSES

         In  addition  to its  other  obligations  under  Section  6(a)  of this
Agreement,  the  Company  hereby  agrees  to  reimburse  the  Underwriters  on a
quarterly  basis  for all  reasonable  legal  and  other  expenses  incurred  in
connection with  investigating  or defending any claim,  action,  investigation,
inquiry or other  proceeding  arising out of or based upon in whole or part, (i)
as described in Section 6(a), any untrue  statement or alleged untrue  statement
of a material fact contained in any  preliminary  prospectus,  the  Registration
Statement or the  Prospectus or any amendment or supplement to the  Registration
Statement or the  Prospectus,  or the  omission or alleged  omission to state in
such  document a material  fact required to be stated in it or necessary to make
the statements in it not misleading,  (ii) any inaccuracy in the representations
and  warranties  of the Company  contained  herein,  or (iii) any failure of the
Company to perform its obligations hereunder or under law in connection with the
transactions  contemplated  hereby,  notwithstanding  the  absence of a judicial
determination as to the propriety and  enforceability  of the obligations  under
this Section 7 and the  possibility  that such payment might later be held to be
improper;  provided, however, that, to the extent any such payment is ultimately
held to be improper,  the persons  receiving such payments shall promptly refund
them.

8.       TERMINATION

         The obligations of the several Underwriters under this Agreement may be
terminated  at any time on or prior to the Closing Date (or, with respect to the
Option Shares, on or prior to the Option Closing Date), by notice to the Company
from the  Underwriters,  without liability on the part of any Underwriter to the


                                      -35-


                                                      


Company if, prior to delivery and payment for the Firm Shares or Option  Shares,
as the case may be, in the sole judgment of the Underwriters, (a) trading in any
of the  equity  securities  of the  Company  shall  have been  suspended  by the
Commission or by the Nasdaq National Market, (b) trading in securities generally
on the New York Stock  Exchange or the Nasdaq  National  Market  shall have been
suspended  or limited or minimum  or maximum  prices  shall have been  generally
established on such exchange, or additional material governmental  restrictions,
not in force on the date of this Agreement, shall have been imposed upon trading
in securities  generally by such  exchange or by order of the  Commission or any
court or other  governmental  authority,  (c) a general banking moratorium shall
have been  declared  by either  Federal or New York State  authorities,  (d) any
material  adverse  change in the financial or  securities  markets in the United
States, or in political,  financial or economic  conditions in the United States
or any  outbreak or material  escalation  of  hostilities  or other  calamity or
crises,  shall have occurred,  the effect of which is such as to make it, in the
sole judgment of the Underwriters, impracticable to market the Shares, (e) there
has been a  material  adverse  change  since  the  respective  dates as of which
information  is given in the  Registration  Statement and the  Prospectus in the
general affairs, business, business prospects, properties, management, condition
(financial or  otherwise),  net worth or results of operations of the Company or
any Subsidiary,  whether or not arising from transactions in the ordinary course
of  business,  in each case other than as described  in or  contemplated  by the
Registration Statement and the Prospectus,  or (f) the Company or any Subsidiary
has sustained any material loss or interference  with its business or properties
from  fire,  explosion,  flood,  earthquake  or other  casualty,  whether or not
covered by insurance,  or from any labor dispute or any court or  legislative or
other  government  action,  order  or  decree,  which  is not  described  in the
Registration   Statement  and  the  Prospectus,   if  in  the  judgment  of  the
Underwriters  any such  development  makes it  impracticable  or  inadvisable to
consummate the sale and delivery of the Shares by the Underwriters at the public
offering price.

9.       SUBSTITUTION OF UNDERWRITERS

         If any one or more of the Underwriters shall fail or refuse to purchase
the Shares which it or they have agreed to purchase hereunder, and the aggregate
number of Shares which such defaulting  Underwriter or  Underwriters  agreed but
failed or refused to purchase is not more than one-tenth of the aggregate number
of Shares, the other Underwriters shall be obligated, severally, to purchase the


                                      -36-


                                                      

Shares which such defaulting  Underwriter or  Underwriters  agreed but failed or
refused to purchase,  in the  proportions  which the number of Shares which they
have  respectively  agreed  to  purchase  pursuant  to  Section  1 bears  to the
aggregate  number of Shares which all such  nondefaulting  Underwriters  have so
agreed  to  purchase,  or in such  other  proportions  as the  Underwriters  may
specify,  provided that in no event shall the maximum number of Shares which any
Underwriter has become obligated to purchase  pursuant to Section 1 be increased
pursuant  to this  Section 9 by more  than  one-ninth  of such  number of Shares
without the prior written  consent of such  Underwriter.  If any  Underwriter or
Underwriters  shall fail or refuse to  purchase  any  Shares  and the  aggregate
number of Shares which such defaulting  Underwriter or  Underwriters  agreed but
failed or refused to purchase  exceeds  one-tenth of the aggregate number of the
Shares and arrangements satisfactory to the Underwriters and the Company for the
purchase of such Shares are not made  within 48 hours after such  default,  this
Agreement  will  terminate  without  liability on the part of any  nondefaulting
Underwriter  or the  Company for the  purchase or sale of any Shares  under this
Agreement.  In any such  case  which  does not  result  in  termination  of this
Agreement,  either  the  Underwriters  or the  Company  shall  have the right to
postpone the Closing Date,  but in no event for longer than seven days, in order
that  the  required  changes,  if any,  in the  Registration  Statement  and the
Prospectus or in any other documents or arrangements may be effected. Any action
taken  pursuant to this Section 9 shall not relieve any  defaulting  Underwriter
from  liability  in  respect  of any  default  of such  Underwriter  under  this
Agreement.

10.      MISCELLANEOUS

         Notice given pursuant to any of the provisions of this Agreement  shall

         This  Agreement  has been and is made  solely  for the  benefit  of the
several  Underwriters,  the Company and the controlling  persons,  directors and
officers referred to in Section 6, and their respective  successors and assigns,

the  laws of the  State  of New  York  applicable  to  contracts  made and to be
performed entirely within such State.

         This  Agreement  may not be  amended  or  modified  except in a writing
signed by both parties.

         This Agreement may be signed in two or more  counterparts with the same

         In case any provision in this  Agreement  shall be invalid,  illegal or
unenforceable,  the  validity,  legality  and  enforceability  of the  remaining
provisions shall not in any way be affected or impaired thereby.

         Please  confirm that the foregoing  correctly  sets forth the Agreement
among the Company and the several Underwriters.

                                    ARTICLE 2

                        DURATION AND EXERCISE OF WARRANT

2.1      DURATION OF WARRANT

         The  Warrantholder  may exercise this Warrant at any time and from time
to time after 9:00 a.m.,  New York time, on  ____________,  1997 [one year after
the date of closing]  and before  5:00 p.m.,  New York time,  on the  Expiration
Date. If this Warrant is not exercised on the  Expiration  Date, it shall become
void, and all rights hereunder shall thereupon cease.

2.2      METHOD OF EXERCISE

                  (a) The Warrantholder  may exercise this Warrant,  in whole or
in part,  by  presentation  and  surrender of this Warrant to the Company at its
corporate office at 375 West Street, West Bridgewater,  Massachusetts  62379, or
at the  office of its stock  transfer  agent,  if any,  with the  Exercise  Form
annexed  hereto duly executed and, in the event of an exercise for cash pursuant
to Section  2.3(a),  accompanied  by payment of the full Exercise Price for each
Warrant Share to be purchased.

                  (b) Upon receipt of this Warrant with the Exercise  Form fully
executed and, in the event of an exercise for cash  pursuant to Section  2.3(a),


                                      A-5


                                                      


accompanied  by payment of the aggregate  Exercise  Price for the Warrant Shares
for which this Warrant is then being  exercised,  the Company  shall cause to be
issued  certificates  for the total  number of whole  shares of Common Stock for
which this  Warrant is being  exercised  (adjusted  to reflect the effect of the
anti-dilution  provisions contained in Article 3 hereof, if any, and as provided
in Section 2.4 hereof) in such  denominations  as are  requested for delivery to
the Warrantholder,  and the Company shall thereupon deliver such certificates to
the  Warrantholder.  A net issuance exercise pursuant to Section 2.3(b) shall be
effective  upon  receipt  by the  Company  of this  Warrant  together  with  the
aforesaid written statement,  or on such later date as is specified therein (the
"NET ISSUANCE EXERCISE DATE"), and, at the election of the Holder hereof, may be
made  contingent  upon the closing of the sale of the Warrant Shares in a Public
Offering.  The  Warrantholder  shall be deemed to be the holder of record of the
shares of Common Stock  issuable upon such exercise as of the time of receipt of
the Exercise Form and payment in accordance with the preceding sentence,  in the
case of an  exercise  for cash  pursuant  to  Section  2.3(a),  or as of the Net
Issuance  Exercise  Date,  in the case of a net  issuance  exercise  pursuant to
Section  2.3(b),  notwithstanding  that the stock  transfer books of the Company
shall then be closed or that  certificates  representing  such  shares of Common
Stock shall not then be actually delivered to the Warrantholder.  If at the time
this Warrant is exercised, a Registration Statement is not in effect to register
under the  Securities  Act the Warrant  Shares  issuable  upon  exercise of this
Warrant,  the  Company  may,  in the case of an  exercise  for cash  pursuant to
Section  2.3(a)  or in  the  case  of a  net  issuance  exercise  prior  to  the
satisfaction of any holding period  required by Rule 144  promulgated  under the
Securities Act, require the Warrantholder to make such representations,  and may
place the legends on certificates  representing  the Warrant  Shares,  as may be
reasonably  required  in the  opinion of  counsel  to the  Company to permit the
Warrant Shares to be issued without such registration.

                  (c) In case the Warrantholder shall exercise this Warrant with
respect to less than all of the Warrant Shares that may be purchased  under this
Warrant,  the Company shall  execute as of the exercise date (or, if later,  the
Net  Issuance  Exercise  Date) a new warrant in the form of this Warrant for the
balance of such Warrant Shares and deliver such new warrant to the Warrantholder
within 10 days  following  the  exercise  date (or, if later,  the Net  Issuance
Exercise Date).

                  (d) The  Company  shall  pay any and all  stock  transfer  and
similar  taxes  which may be payable in respect of the  issuance  of any Warrant
Shares.


                                      A-6


                                                      


2.3      EXERCISE OF WARRANT

                  (a) Right to Exercise for Cash.  This Warrant may be exercised
by the Holder by  delivery  of payment to the  Company,  for the  account of the
Company,  by cash, by certified or bank cashier's check or by wire transfer,  of
the Exercise  Price for the number of Warrant  Shares  specified in the Exercise
Form in lawful money of the United States of America.

                  (b) Right to  Exercise  on a Net  Issuance  Basis.  In lieu of
exercising  this Warrant for cash pursuant to Section  2.3(a),  the Holder shall
have the  right to  exercise  this  Warrant  or any  portion  thereof  (the "NET
ISSUANCE  RIGHT") into shares of Common Stock as provided in this Section 2.3(b)
at any time or from time to time  during the  period  specified  in Section  2.1
hereof by the  surrender of this Warrant to the Company with a duly executed and
completed Exercise Form marked to reflect net issuance  exercise.  Upon exercise
of the Net Issuance Right with respect to a particular  number of shares subject
to this  Warrant  and noted on the  Exercise  Form (the  "NET  ISSUANCE  WARRANT
SHARES"), the Company shall deliver to the Holder (without payment by the Holder
of any  Exercise  Price or any cash or other  consideration)  (X) that number of
shares  of fully  paid and  nonassessable  Common  Stock  equal to the  quotient
obtained by dividing the value of this Warrant (or the specified portion hereof)
on  the  Net  Issuance  Exercise  Date,  which  value  shall  be  determined  by
subtracting (A) the aggregate  Exercise Price of the Net Issuance Warrant Shares
immediately  prior  to the  exercise  of the Net  Issuance  Right  from  (B) the
aggregate  fair market value of the Net Issuance  Warrant  Shares  issuable upon
exercise of this Warrant (or the specified  portion  hereof) on the Net Issuance
Exercise  Date (as herein  defined) by (Y) the fair market value of one share of
Common Stock on the Net Issuance Exercise Date (as herein defined).

         Expressed as a formula, such net issuance exercise shall be computed as
follows:


         X =      B-A
                   Y


 Where:           X =      the  number  of  shares  of  Common Stock that may be
                           issued to the Holder


                                      A-7



                                                      


                  Y =      the fair market value  ("FMV") of one share of Common
                           Stock as of the Net Issuance Exercise Date

                  A =      the  aggregate  Exercise  Price  (i.e.,  the  product
                           determined by  multiplying  the Net Issuance  Warrant
                           Shares by the Exercise Price)

                  B =      the  aggregate  FMV  (i.e., the product determined by
                           multiplying  the  FMV  by  the  Net  Issuance Warrant
                           Shares)


                  (c)  Determination  of Fair Market Value. For purposes of this
Section  2.3,  "FAIR  MARKET  VALUE"  of a share of  Common  Stock as of the Net
Issuance Exercise Date shall mean:

                           (i)  if  the  Net  Issuance  Right  is  exercised  in
connection  with and  contingent  upon a Public  Offering,  and if the Company's
Registration  Statement  relating  to such  Public  Offering  has been  declared
effective by the SEC, then the initial "Price to Public"  specified in the final
Prospectus with respect to such offering.

                           (ii) if the Net  Issuance  Right is not  exercised in
connection with and contingent upon a Public Offering, then as follows:

                           (A) If  traded  on a  securities  exchange,  the fair
         market  value of the Common  Stock shall be deemed to be the average of
         the closing prices of the Common Stock on such exchange over the 30-day
         period  ending five  business  days prior to the Net Issuance  Exercise
         Date;

                           (B) If traded on the  Nasdaq  National  Market or the
         Nasdaq SmallCap Market, the fair market value of the Common Stock shall
         be deemed to be the average of the last  reported  sales  prices of the
         Common Stock on such Market over the 30-day period ending five business
         days prior to the Net Issuance Exercise Date;

                           (C) If  traded  over-the-counter  other  than  on the
         Nasdaq National Market or the Nasdaq SmallCap  Market,  the fair market
         value of the  Common  Stock  shall be deemed to be the  average  of the
         closing bid 


                                      A-8


                                                      

         prices of the Common Stock over the 30-day  period ending five business
         days prior to the Net Issuance Exercise Date; and

                           (D) If  there  is no  public  market  for the  Common
         Stock,  then fair market value shall be determined by mutual  agreement
         of the Warrantholder and the Company,  and if the Warrantholder and the
         Company are unable to so agree,  at the Company's  sole expense,  by an
         investment  banker of national  reputation  selected by the Company and
         reasonably acceptable to the Warrantholder.

2.4      RESERVATION OF SHARES

         The Company hereby agrees that at all times there shall be reserved for
issuance  and  delivery  upon  exercise of this Warrant such number of shares of
Common Stock or other  shares of capital  stock of the Company from time to time
issuable  upon  exercise  of  this  Warrant.  All  such  shares  shall  be  duly
authorized,  and when issued upon such exercise,  shall be validly issued, fully
paid and  non-assessable,  free  and  clear of all  liens,  security  interests,
charges and other  encumbrances  or restrictions on sale (except as contemplated
by  Sections  2.2(b)  and 5.2) and free and  clear of all  preemptive  and other
similar rights.

2.5      FRACTIONAL SHARES

         The Company  shall not be required to issue any  fraction of a share of
its capital  stock in connection  with the exercise of this Warrant,  and in any
case where the  Warrantholder  would,  except for the provisions of this Section
2.5,  be  entitled  under the terms of this  Warrant to receive a fraction  of a
share upon the exercise of this Warrant, the Company shall, upon the exercise of
this  Warrant,  pay to the  Warrantholder  an amount  in cash  equal to the fair
market value of such fractional share as of the exercise date (or, if applicable
and a later date, the Net Issuance Exercise Date).

2.6      LISTING

         Prior to the  issuance of any shares of Common  Stock upon  exercise of
this  Warrant,  the  Company  shall  secure the listing of such shares of Common
Stock upon each national  securities  exchange or automated quotation system, if
any,  upon which  shares of Common  Stock are then  listed  (subject to official
notice of

                                      A-9


                                                      

issuance upon exercise of this Warrant) and shall maintain, so long as any other
shares of Common Stock shall be so listed,  such listing of all shares of Common
Stock from time to time  issuable  upon the  exercise of this  Warrant;  and the
Company  shall  so  list on  each  national  securities  exchange  or  automated
quotation  system,  and shall  maintain  such  listing  of, any other  shares of
capital  stock of the Company  issuable upon the exercise of this Warrant if and
so long as any  shares  of the same  class  shall  be  listed  on such  national
securities exchange or automated quotation system.

                                    ARTICLE 3

                      ADJUSTMENT OF SHARES OF COMMON STOCK
                        PURCHASABLE AND OF EXERCISE PRICE

         The Exercise  Price and the number and kind of Warrant  Shares shall be
subject to adjustment  from time to time upon the happening of certain events as
provided in this Article 3.

3.1      MECHANICAL ADJUSTMENTS

                  (a) If at any time prior to the  exercise  of this  Warrant in
full,  the Company  shall (i) declare a dividend or make a  distribution  on the
Common Stock  payable in shares of its capital stock  (whether  shares of Common
Stock or of capital stock of any other  class);  (ii)  subdivide,  reclassify or
recapitalize its outstanding Common Stock into a greater number of shares; (iii)
combine,  reclassify or recapitalize its outstanding Common Stock into a smaller
number  of  shares;   or  (iv)  issue  any  shares  of  its  capital   stock  by
reclassification  of its Common Stock  (including any such  reclassification  in
connection  with a  consolidation  or a  merger  in  which  the  Company  is the
continuing corporation),  the number of Warrant Shares issuable upon exercise of
the Warrant  and/or the Exercise  Price in effect at the time of the record date
of such dividend, distribution,  subdivision,  combination,  reclassification or
recapitalization  shall be adjusted so that the Warrantholder  shall be entitled
to receive the aggregate  number and kind of shares  which,  if this Warrant had
been exercised in full immediately prior to such event, the Warrantholder  would
have owned upon such  exercise  and been  entitled  to receive by virtue of such
dividend,   distribution,   subdivision,   combination,    reclassification   or
recapitalization.  Any adjustment  required by this Section 3.1(a) shall be made
successively  immediately  after the record  date,  in the case of a


                                      A-10


                                                      


dividend or  distribution,  or the effective date, in the case of a subdivision,
combination, reclassification or recapitalization, to allow the purchase of such
aggregate number and kind of shares.

                  (b) If any time prior to the exercise of this Warrant in full,
the Company shall fix a record date for the issuance or making of a distribution
to all holders of the Common Stock  (including any such  distribution to be made
in connection with a  consolidation  or merger in which the Company is to be the
continuing  corporation) of evidences of its indebtedness,  any other securities
of the Company or any cash,  property or other assets  (excluding a combination,
reclassification or recapitalization referred to in Section 3.1(a), regular cash
dividends  or cash  distributions  paid  out of net  profits  legally  available
therefor  and in the  ordinary  course of business  if the full amount  thereof,
together with the value of other dividends and distributions  made substantially
concurrently  therewith or pursuant to a plan which includes payment thereof, is
equivalent  to not more than 5% of the  Company's  net  worth,  or  subscription
rights,  options  or  warrants  for  Common  Stock or Common  Stock  Equivalents
(excluding  those  referred to in Section  3.1(b)) (any such  nonexcluded  event
being  herein  called  a  "SPECIAL  DIVIDEND")),  the  Exercise  Price  shall be
decreased immediately after the record date for such Special Dividend to a price
determined by multiplying  the Exercise Price then in effect by a fraction,  the
numerator  of which shall be the then  current  market price of the Common Stock
(as defined in Section  3.1(e)) on such  record date less the fair market  value
(as  determined  in good faith by the Board of  Directors of the Company) of the
evidences of  indebtedness,  securities  or property,  or other assets issued or
distributed in such Special Dividend  applicable to one share of Common Stock or
of such subscription  rights or warrants applicable to one share of Common Stock
and the denominator of which shall be the then current market price per share of
Common Stock (as so determined). Any adjustments required by this Section 3.1(b)
shall be made successively whenever such a record date is fixed and in the event
that  such  distribution  is not so made,  the  Exercise  Price  shall  again be
adjusted to be the Exercise Price that was in effect  immediately  prior to such
record date.

                  (c) If at any time prior to the  exercise  of this  Warrant in
full, the Company shall make a  distribution  to all holders of the Common Stock
of stock of a subsidiary or securities  convertible into or exercisable for such
stock,  then in lieu of an  adjustment  in the  Exercise  Price or the number of
Warrant   Shares   purchasable   upon  the  exercise  of  this   Warrant,   each
Warrantholder,  upon the  exercise  hereof


                                      A-11


                                                      


at any time after  such  distribution,  shall be  entitled  to receive  from the
Company,  such subsidiary or both, as the Company shall determine,  the stock or
other  securities to which such  Warrantholder  would have been entitled if such
Warrantholder had exercised this Warrant immediately prior thereto,  all subject
to further  adjustment  as  provided in this  Article 3, and the  Company  shall
reserve,  for the life of the Warrant,  such  securities  of such  subsidiary or
other corporation; provided, however, that no adjustment in respect of dividends
or interest on such stock or other  securities  shall be made during the term of
this Warrant or upon its exercise.

                  (d) Whenever the Exercise  Price payable upon exercise of each
Warrant is adjusted  pursuant to one or more of  paragraphs  (a) and (b) of this
Section 3.1, the Warrant Shares shall  simultaneously be adjusted by multiplying
the number of Warrant Shares initially issuable upon exercise of each Warrant by
the  Exercise  Price in effect on the date  thereof and  dividing the product so
obtained by the Exercise Price, as adjusted.

                  (e) For the purpose of any computation under this Section 3.1,
the current  market  price per share of Common Stock at any date shall be deemed
to be the average of the daily closing  prices for 20  consecutive  trading days
commencing  30 trading  days  before such date.  The closing  price for each day
shall be the last sale price regular way or, in case no such reported sales take
place on such day, the average of the last reported bid and asked prices regular
way, in either case on the principal national  securities  exchange on which the
Common  Stock is admitted to trading or listed,  or if not listed or admitted to
trading on such exchange,  the  representative  closing bid price as reported by
Nasdaq,  or other similar  organization  if Nasdaq is no longer  reporting  such
information, or if not so available, the fair market price as determined in good
faith by the Board of Directors of the Company.

                  (f) No  adjustment  in the  Exercise  Price  shall be required
unless such  adjustment  would  require an increase or decrease of at least five
cents ($.05) in such price;  provided,  however,  that any adjustments  which by
reason  of this  paragraph  (f) are not  required  to be made  shall be  carried
forward and taken into account in any subsequent  adjustment.  All  calculations
under  this  Section  3.1 shall be made to the  nearest  cent or to the  nearest
one-hundredth of a share, as the case may be.  Notwithstanding  anything in this
Section 3.1 to the  contrary,  the


                                      A-12


                                                      


Exercise  Price shall not be reduced to less than the then existing par value of
the Common Stock as a result of any adjustment made hereunder.

                  (g)  In the  event  that  at  any  time,  as a  result  of any
adjustment made pursuant to Section 3.1(a),  the Warrantholder  thereafter shall
become  entitled to receive any shares of the Company  other than Common  Stock,
thereafter  the number of such other shares so  receivable  upon exercise of any
Warrant  shall be  subject  to  adjustment  from time to time in a manner and on
terms as nearly  equivalent as practicable to the provisions with respect to the
Common Stock contained in this Section 3.1.

                  (h) In case  any  event  shall  occur as to  which  the  other
provisions  of this  Article 3 are not strictly  applicable  but as to which the
failure to make any  adjustment  would not fairly  protect the  purchase  rights
represented  by this  Warrant  in  accordance  with  the  essential  intent  and
principles hereof then, in each such case, the  Warrantholders  representing the
right to purchase a majority of the Warrant  Shares  subject to all  outstanding
Warrants may appoint a firm of  independent  public  accountants  of  recognized
national standing reasonably  acceptable to the Company,  which shall give their
opinion as to the adjustment,  if any, on a basis  consistent with the essential
intent and  principles  established  herein,  necessary to preserve the purchase
rights  represented by the Warrants.  Upon receipt of such opinion,  the Company
will  promptly  mail a copy  thereof  to the  Warrantholder  and shall  make the
adjustments  described therein. The fees and expenses of such independent public
accountants shall be borne by the Company.

                  (i) If, as a result of an  adjustment  made  pursuant  to this
Article 3, the Holder of any Warrant  thereafter  surrendered for exercise shall
become  entitled to receive  shares of two or more  classes of capital  stock or
shares of Common  Stock and other  capital  stock of the  Company,  the Board of
Directors (whose  determination  shall be conclusive and shall be described in a
written  notice to the Holder of any  Warrant  promptly  after such  adjustment)
shall  determine the allocation of the adjusted  Exercise Price between or among
shares or such  classes  of  capital  stock or shares of Common  Stock and other
capital stock.

3.2      NOTICES OF ADJUSTMENT



                                      A-13


                                                      


         Whenever the number of Warrant Shares or the Exercise Price is adjusted
as herein  provided,  the Company  shall  prepare and deliver  forthwith  to the
Warrantholder a certificate signed by its President,  and by any Vice President,
Treasurer or Secretary,  setting forth the adjusted number of shares purchasable
upon the exercise of this  Warrant and the  Exercise  Price of such shares after
such  adjustment,  setting forth a brief  statement of the facts  requiring such
adjustment and setting forth the computation by which adjustment was made.

3.3      NO ADJUSTMENT FOR DIVIDENDS

         Except as provided in Section 3.1 of this  Agreement,  no adjustment in
respect of any cash  dividends  shall be made during the term of this Warrant or
upon the exercise of this Warrant.

3.4      PRESERVATION OF PURCHASE RIGHTS IN CERTAIN TRANSACTIONS

         In case of any reclassification, capital reorganization or other change
of  outstanding  shares of Common Stock (other than a subdivision or combination
of the outstanding  Common Stock and other than a change in the par value of the
Common Stock) or in case of any  consolidation  or merger of the Company with or
into  another  corporation  (other than merger  with a  subsidiary  in which the
Company  is  the  continuing  corporation  and  that  does  not  result  in  any
reclassification,  capital  reorganization or other change of outstanding shares
of Common Stock of the class  issuable  upon exercise of this Warrant) or in the
case of any sale,  lease,  transfer or conveyance to another  corporation of the
property  and  assets of the  Company  as an  entirety  or  substantially  as an
entirety,  the Holder of this Warrant shall have the right thereafter to receive
on the exercise of this Warrant the kind and amount of securities, cash or other
property  which the Holder  would have  owned or have been  entitled  to receive
immediately after such reorganization, reclassification,  consolidation, merger,
statutory  exchange,   sale  or  conveyance  had  this  Warrant  been  exercised
immediately   prior   to   the   effective   date   of   such    reorganization,
reclassification,  consolidation, merger, statutory exchange, sale or conveyance
and in any such case, if necessary,  appropriate adjustment shall be made in the
application  of the  provisions  set forth in this Article 3 with respect to the
rights and  interests  thereafter  of the Holder of this Warrant to the end that
the provisions set forth in this Article 3 shall thereafter  correspondingly  be
made  applicable,  as nearly as may  reasonably be, in relation to any shares of
stock or other securities or property thereafter  deliverable on the exercise of
this

                                      A-14


                                                      


Warrant.  The provisions of this Section 3.4 shall similarly apply to successive
reorganizations,    reclassifications,    consolidations,   mergers,   statutory
exchanges,  sales or  conveyances.  The  issuer of any  shares of stock or other
securities or property  thereafter  deliverable  on the exercise of this Warrant
shall be responsible  for all of the  agreements and  obligations of the Company
hereunder. Notice of any such reorganization,  reclassification,  consolidation,
merger,  statutory  exchange,  sale  or  conveyance  and of said  provisions  so
proposed  to be made,  shall be mailed to the Holders of the  Warrants  not less
than 30 days  prior to such  event.  A sale of all or  substantially  all of the
assets of the Company for a  consideration  consisting  primarily of  securities
shall be deemed a consolidation or merger for the foregoing purposes.

3.5      FORM OF WARRANT AFTER ADJUSTMENTS

         The form of this Warrant need not be changed because of any adjustments
in the Exercise Price or the number or kind of the Warrant Shares,  and Warrants
theretofore  or  thereafter  issued may  continue  to express the same price and
number and kind of shares as are stated in this Warrant, as initially issued.

3.6      TREATMENT OF WARRANTHOLDER

         Prior to due presentment for  registration of transfer of this Warrant,
the Company may deem and treat the  Warrantholder  as the absolute owner of this
Warrant  (notwithstanding any notation of ownership or other writing hereon) for
all purposes and shall not be affected by any notice to the contrary.

                                    ARTICLE 4

              OTHER PROVISIONS RELATING TO RIGHTS OF WARRANTHOLDER

4.1      NO RIGHTS AS SHAREHOLDERS; NOTICE TO WARRANTHOLDERS

         Nothing contained in this Warrant shall be construed as conferring upon
the Warrantholder or his, her or its transferees the right to vote or to receive
dividends or to consent or to receive  notice as a shareholder in respect of any
meeting of  shareholders  for the election of directors of the Company or of any
other matter,  or any rights  whatsoever  as  shareholders  of the Company.  The
Company shall give


                                      A-15

                                                      


notice  to the  Warrantholder  by  registered  mail if at any time  prior to the
expiration  or exercise in full of the  Warrants,  any of the  following  events
shall occur:

                  (a) the Company  shall  authorize  the payment of any dividend
         payable in any securities  upon shares of Common Stock or authorize the
         making of any  distribution  (other than a cash dividend subject to the
         parenthetical  set forth in Section  3.1(b))  to all  holders of Common
         Stock;

                  (b) the Company shall authorize the issuance to all holders of
         Common Stock of any  additional  shares of Common Stock or Common Stock
         Equivalents  or of rights,  options or  warrants  to  subscribe  for or
         purchase  Common  Stock or  Common  Stock  Equivalents  or of any other
         subscription rights, options or warrants;

                  (c) a  dissolution,  liquidation  or winding up of the Company
         shall be proposed; or

                  (d) a capital reorganization or reclassification of the Common
         Stock  (other than a  subdivision  or  combination  of the  outstanding
         Common  Stock  and other  than a change in the par value of the  Common
         Stock)  or any  consolidation  or merger  of the  Company  with or into
         another  corporation (other than a consolidation or merger in which the
         Company is the continuing  corporation  and that does not result in any
         reclassification  or change of Common Stock outstanding) or in the case
         of any sale or conveyance to another corporation of the property of the
         Company as an entirety or substantially as an entirety.

         Such notice  shall be given (i) at least 10 Business  Days prior to the
date  fixed as a record  date or  effective  date or the date of  closing of the
Company's  stock  transfer  books  for  the  determination  of the  shareholders
entitled to such  dividend,  distribution  or  subscription  rights,  or for the
determination  of the  shareholders  entitled to vote on such  proposed  merger,
consolidation,  sale, conveyance,  dissolution,  liquidation or winding up. Such
notice shall specify such record date or the date of closing the stock  transfer
books,  as the case may be.  Failure to provide such notice shall not affect the
validity of any action taken in connection  with such dividend,  distribution or
subscription  rights,  or  proposed  merger,  consolidation,  sale,  conveyance,
dissolution, liquidation or winding up.


                                      A-16



                                                      


4.2      LOST, STOLEN, MUTILATED OR DESTROYED WARRANTS

         If this Warrant is lost,  stolen,  mutilated or destroyed,  the Company
may, on such terms as to  indemnity  or  otherwise  as it may in its  reasonable
judgment  impose (which shall, in the case of a mutilated  Warrant,  include the
surrender  thereof),  issue a new Warrant of like denomination and tenor as, and
in substitution for, this Warrant.

                                    ARTICLE 5

                       SPLIT-UP, COMBINATION, EXCHANGE AND
                     TRANSFER OF WARRANTS AND WARRANT SHARES

5.1      SPLIT-UP, COMBINATION AND EXCHANGE OF WARRANTS

         This Warrant may be split up, combined or exchanged for another Warrant
or Warrants  containing  the same terms to purchase a like  aggregate  number of
Warrant Shares.  If the  Warrantholder  desires to split up, combine or exchange
this Warrant,  he, she or it shall make such request in writing delivered to the
Company and shall  surrender to the Company this Warrant and any other  Warrants
to be so  split  up,  combined  or  exchanged.  Upon any  such  surrender  for a
split-up,  combination or exchange, the Company shall execute and deliver to the
person  entitled  thereto  a  Warrant  or  Warrants,  as the case may be,  as so
requested. The Company shall not be required to effect any split-up, combination
or  exchange  which  will  result in the  issuance  of a Warrant  entitling  the
Warrantholder to purchase upon exercise a fraction of a share of Common Stock or
a fractional  Warrant.  The Company may require such  Warrantholder to pay a sum
sufficient  to cover  any tax or  governmental  charge  that may be  imposed  in
connection with any split-up, combination or exchange of Warrants.

5.2      RESTRICTIONS ON TRANSFER, RESTRICTIVE LEGENDS

         Except as otherwise  permitted by this Section 5.2,  each Warrant shall
(and each Warrant issued upon direct or indirect transfer or in substitution for
any  Warrant  issued  pursuant  to Section  5.1  shall) be stamped or  otherwise
imprinted with a legend in substantially the following form:


                                      A-17



                                                      

          "THIS  WARRANT AND ANY SHARES  ACQUIRED UPON THE EXERCISE OF THIS
     WARRANT HAVE NOT BEEN REGISTERED  UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED, AND MAY NOT BE SOLD OR OTHERWISE  TRANSFERRED EXCEPT PURSUANT
     TO AN  EFFECTIVE  REGISTRATION  STATEMENT  FILED  UNDER  SUCH  ACT  OR
     PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT."

         Except  as  otherwise   permitted  by  this  Section  5.2,  each  stock
certificate  for Warrant Shares issued upon the exercise of any Warrant and each
stock  certificate  issued  upon the  direct or  indirect  transfer  of any such
Warrant  Shares  shall be  stamped  or  otherwise  imprinted  with a  legend  in
substantially the following form:

          "THE  SHARES  REPRESENTED  BY  THIS  CERTIFICATE  HAVE  NOT  BEEN
     REGISTERED  UwNDER THE SECURITIES ACT OF 1933, AS AMENDED,  AND MAY NOT
     BE SOLD OR  OTHERWISE  TRANSFERRED  EXCEPT  PURSUANT  TO AN  EFFECTIVE
     REGISTRATION  STATEMENT  FILED  UNDER  SUCH  ACT  OR  PURSUANT  TO  AN
     EXEMPTION FROM REGISTRATION UNDER SUCH ACT."

         Notwithstanding  the  foregoing,  the  Warrantholder  may  require  the
Company to issue a Warrant or a stock  certificate for Warrant  Shares,  in each
case  without a legend,  if (i) the  issuance  of such  Warrant  Shares has been
registered  under the Securities  Act, (ii) such Warrant or such Warrant Shares,
as the case may be, have been  registered for resale under the Securities Act or
sold pursuant to Rule 144 under the Securities  Act (or a successor  thereto) or
(iii) the  Warrantholder  has  received an opinion of counsel  (who may be house
counsel for such Warrantholder) reasonably satisfactory to the Company that such
registration  is not  required  with  respect to such  Warrant  or such  Warrant
Shares, as the case may be.

                                 ARTICLE 6

               REGISTRATION UNDER THE SECURITIES ACT OF 1933

6.1      PIGGYBACK REGISTRATION

                  (a) Right to Include Registrable Securities. If at any time or
from time to time prior to the second  anniversary of the  Expiration  Date, the
Company  proposes to register any of its securities  under the Securities Act on
any form for the  registration of securities  under such Act, whether or not for
its own account  (other


                                   A-18


                                                      


than by a  registration  statement  on Form S-8 or  other  form  which  does not
include  substantially  the same  information as would be required in a form for
the  general  registration  of  securities  or would  not be  available  for the
Registrable Securities) (a "PIGGYBACK REGISTRATION"),  it shall as expeditiously
as possible give written  notice to all Holders of its intention to do so and of
such  Holders'  rights  under this  Section  6.1.  Such  rights are  referred to
hereinafter as "PIGGYBACK  REGISTRATION RIGHTS." Upon the written request of any
such Holder made within 20 days after receipt of any such notice (which  request
shall  specify  the  Registrable  Securities  intended to be disposed of by such
Holder), the Company shall include in the Registration Statement the Registrable
Securities  which the Company has been so  requested  to register by the Holders
thereof and the Company  shall keep such  registration  statement  in effect and
maintain compliance with each federal and state law or regulation for the period
necessary for such Holder to effect the proposed sale or other  disposition (but
in no event for a period greater than 90 days).

                  (b) Withdrawal of Piggyback  Registration  by Company.  If, at
any time after giving written notice of its intention to register any securities
in a  Piggyback  Registration  but prior to the  effective  date of the  related
Registration  Statement,  the  Company  shall  determine  for any  reason not to
register such securities, the Company shall give notice of such determination to
each Holder and, thereupon,  shall be relieved of its obligation to register any
Registrable Securities in connection with such Piggyback Registration.  All best
efforts  obligations  of the Company  pursuant to Section 6.4 shall cease if the
Company  determines to terminate  prior to such effective date any  registration
where Registrable Securities are being registered pursuant to this Section 6.1.

                  (c) Piggyback Registration of Underwritten Public Offering. If
a Piggyback  Registration involves an offering by or through underwriters,  then
(i) all Holders requesting to have their Registrable  Securities included in the
Company's  Registration  Statement must sell their Registrable Securities to the
underwriters  selected by the Company on the same terms and  conditions as apply
to other selling shareholders and (ii) any Holder requesting to have his, her or
its Registrable  Securities included in such Registration Statement may elect in
writing,  not later than three Business Days prior to the  effectiveness  of the
Registration  Statement filed in connection with such registration,  not to have
his  or  its  Registrable   Securities  so  included  in  connection  with  such
registration.

                                      A-19


                                                      


                  (d)   Payment   of   Registration   Expenses   for   Piggyback
Registration. The Company shall pay all Registration Expenses in connection with
each registration of Registrable  Securities  requested  pursuant to a Piggyback
Registration Right contained in this Section 6.1.

                  (e)  Priority  in  Piggyback  Registration.   If  a  Piggyback
Registration  involves  an  offering by or through  underwriters,  the  Company,
except  as  otherwise  provided  herein,   shall  not  be  required  to  include
Registrable  Shares  therein if and to the extent the  underwriter  managing the
offering reasonably believes in good faith and advises each Holder requesting to
have Registrable  Securities  included in the Company's  Registration  Statement
that such inclusion would materially  adversely affect such offering;  provided,
that (i) if other selling shareholders  without contractual  registration rights
have requested  registration of securities in the proposed offering, the Company
will reduce or eliminate such  securities held by selling  shareholders  without
registration   rights  before  any  reduction  or   elimination  of  Registrable
Securities;  and (ii) any such  reduction  or  elimination  (after  taking  into
account  the  effect  of  clause  (i))  shall be pro rata to all  other  selling
shareholders with contractual registration rights.

6.2      DEMAND REGISTRATION

                  (a)  Request  for  Registration.  If, at any time prior to the
Expiration  Date,  any 25% Holders  request that the Company file a registration
statement  under the  Securities  Act,  as soon as  practicable  thereafter  the
Company shall use its best efforts to file a registration statement with respect
to all Warrant  Shares that it has been so  requested  to include and obtain the
effectiveness  thereof,  and to take all other action necessary under federal or
state law or regulation  to permit the Warrant  Shares that are held and/or that
may be acquired  upon the exercise of the  Warrants  specified in the notices of
the  Holders  or holders  hereof to be sold or  otherwise  disposed  of, and the
Company shall maintain such  compliance with each such federal and state law and
regulation  for the period  necessary  for such Holders or holders to effect the
proposed  sale or other  disposition;  provided,  however,  the Company shall be
entitled to defer such  registration for a period of up to 60 days if and to the
extent  that its Board of  Directors  shall  determine  in good  faith that such
registration would require disclosure of information not then otherwise required
to be disclosed and that such  disclosure  would  adversely  affect any material
business  situation,  transaction or negotiation then proposed,  contemplated or
being  engaged in by the Company.  The Company  shall also


                                      A-20


                                                      


promptly  give  written  notice  to the  Holders  and the  holders  of any other
Warrants  and/or the holders of any  Warrant  Shares who or that have not made a
request to the Company  pursuant to the provisions of this Section 6.2(a) of its
intention to effect any required  registration or  qualification,  and shall use
its best efforts to effect as  expeditiously  as possible such  registration  or
qualification  of all such other  Warrant  Shares that are then held and/or that
may be acquired  upon the  exercise of the  Warrants,  the Holders or holders of
which have requested such  registration or  qualification,  within 15 days after
such  notice  has been  given  by the  Company,  as  provided  in the  preceding
sentence.   The  Company  shall  be  required  to  effect  a   registration   or
qualification pursuant to this Section 6.2(a) on one occasion only.

                  (b) Payment of Registration  Expenses for Demand Registration.
The Company shall pay all  Registration  Expenses in connection  with the Demand
Registration.

                  (c) Selection of Underwriters.  If any Demand  Registration is
requested  to  be  in  the  form  of  an  underwritten  offering,  the  managing
underwriter  shall be Oscar Gruss & Son Incorporated and the co-manager (if any)
and the independent price required under the rules of the NASD (if any) shall be
selected and  obtained by the Holders of a majority of the Warrant  Shares to be
registered.  Such  selection  shall be subject to the Company's  consent,  which
consent shall not be  unreasonably  withheld.  All fees and expenses (other than
Registration   Expenses   otherwise   required  to  be  paid)  of  any  managing
underwriter,  any co-manager or any independent underwriter or other independent
price  required  under  the  rules  of the  NASD  shall  be  paid  for  by  such
underwriters or by the Holders or holders whose shares are being registered.  If
Oscar Gruss & Son Incorporated should decline to serve as managing  underwriter,
the Holders of a majority of the Warrant  Shares to be registered may select and
obtain one or more managing underwriters. Such selection shall be subject to the
Company's consent, which shall not be unreasonably withheld.

                  (d) Procedure for Requesting Demand Registration.  Any request
for a Demand  Registration shall specify the aggregate number of the Registrable
Securities proposed to be sold and the intended method of disposition. Within 10
days after  receipt of such a request the Company  will give  written  notice of
such  registration  request to all Holders,  and,  subject to the limitations of

Securities with respect to which the Company has received  written  requests for
inclusion therein within 15

Business  Days after the date on which such notice is given.  Each such  request

         In  lieu  of  carrying  out  its  obligations  to  effect  a  Piggyback

purchase and purchasing such Registrable  Securities  requested to be registered
in an amount in cash equal to the  difference  between  (a) 95% of the last sale
price of the Common  Stock on the day the request for  registration  is made and

         If and whenever the Company is required to use its best efforts to take
action  pursuant to any Federal or state law or regulation to permit the sale or
other  disposition of any Registrable  Securities that are then held or that may
be  acquired  upon  exercise  of the  Warrants  in order to  effect or cause the

in this Article 6, the Company shall, as expeditiously as practicable:

                  (a)  prepare  and file  with the SEC,  as soon as  practicable
within  60  days  after  the  end  of  the  period  within  which  requests  for

deferral  contained  in  Section  6.2(a)  hereof) a  Registration  Statement  or
Registration  Statements  relating to the  registration on any appropriate  form
under the  Securities  Act,  which form shall be  available  for the sale of the
Registrable  Securities  in  accordance  with the intended  method or methods of
distribution  thereof,  and use its  best  efforts  to cause  such  Registration

documents incorporated by reference after the initial filing of any Registration
Statement, the Company will furnish to the Holders of the Registrable Securities
covered by such Registration  Statement and the underwriters,  if any, copies of
all such documents  proposed to be filed, which documents will be subject to the
review of such Holders and underwriters;


                                      A-22



                                                      


                  (b)  prepare  and  file  with  the  SEC  such  amendments  and
post-effective  amendments  to a  Registration  Statement as may be necessary to
keep such Registration  Statement  effective for 180 days if the offering is not
underwritten, provided, that such 180 day period shall be extended by the number
of days a Prospectus is not available  pursuant to Section 6.4(k) because of the
occurrence  of an event  set forth in  Section  6.4(c)(vi);  cause  the  related
Prospectus to be supplemented by any required Prospectus  supplement,  and as so
supplemented  to be filed  pursuant to Rule 424 under the  Securities  Act;  and
comply with the provisions of the Securities Act with respect to the disposition
of all securities  covered by such Registration  Statement during such period in
accordance  with the intended  methods of disposition by the sellers thereof set
forth in such Registration Statement or supplement to such Prospectus;

                  (c) notify the selling  Holders of Registrable  Securities and
the  managing  underwriters,  if any,  promptly,  and (if  requested by any such
Person) confirm such advice in writing,  (i) when a Prospectus or any Prospectus
supplement or  post-effective  amendment has been filed,  and, with respect to a
Registration Statement or any post-effective amendment, when the same has become
effective;  (ii) of any request by the SEC for  amendments or  supplements  to a
Registration  Statement or related  Prospectus  or for  additional  information;
(iii) of the issuance by the SEC of any stop order suspending the  effectiveness
of a  Registration  Statement  or the  initiation  of any  proceedings  for that
purpose;  (iv) if at any time the  representations and warranties of the Company
contemplated  by  paragraph  (m)  below  ceases  to be true and  correct  in all
material  respects;  (v) of the receipt by the Company of any notification  with
respect  to the  suspension  of  the  qualification  of  any of the  Registrable
Securities for sale in any  jurisdiction or the initiation or threatening of any
proceeding for such purposes;  and (vi) of the happening of any event that makes
any  statement  of a  material  fact  made in the  Registration  Statement,  the
Prospectus  or any document  incorporated  therein by reference  untrue or which
requires the making of any changes in the  Registration  Statement or Prospectus
so that they will not contain any untrue statement of a material fact or omit to
state any material fact  required to be stated  therein or necessary to make the
statements therein not misleading:

                  (d) make every  reasonable  effort to obtain the withdrawal of
any order  suspending  the  effectiveness  of a  Registration  Statement  at the
earliest possible moment;

                                      A-23



                                                      


                  (e) if  reasonably  requested  by the  managing  underwriters,
immediately  incorporate in a Prospectus supplement or post-effective  amendment
such  information  as the managing  underwriters  believe (on advice of counsel)
should be included  therein as required by applicable  law relating to such sale
of Registrable  Securities,  including,  without  limitation,  information  with
respect to the purchase price being paid for the Registrable  Securities by such
underwriters  and  with  respect  to any  other  terms of the  underwritten  (or
"best-efforts"  underwritten)  offering;  and make all required  filings of such
Prospectus  supplement  or  post-effective  amendment as soon as notified of the
matters to be  incorporated  in such  Prospectus  supplement  or  post-effective
amendment;

                  (f) furnish to each selling Holder of  Registrable  Securities
and each managing  underwriter,  without charge, at least one signed copy of the
Registration  Statement  and any  post-effective  amendment  thereto,  including
financial  statements  and  schedules,  all  documents  incorporated  therein by
reference and all exhibits (including those incorporated by reference);

                  (g) deliver to each selling Holder of  Registrable  Securities
and the  underwriters,  if any, without charge, as many copies of the Prospectus
or  Prospectuses  (including  each  preliminary  prospectus)  any  amendment  or
supplement thereto as such Persons may reasonably request;  the Company consents
to the use of such Prospectus or any amendment or supplement  thereto by each of
the selling Holders of Registrable  Securities and the underwriters,  if any, in
connection with the offering and sale of the Registrable  Securities  covered by
such Prospectus or any amendment or supplement thereto;

                  (h) prior to any public  offering of  Registrable  Securities,
cooperate with the selling Holders of Registrable Securities,  the underwriters,
if any, and their  respective  counsel in connection  with the  registration  or
qualification  of such  Registrable  Securities  for  offer  and sale  under the
securities  or Blue Sky laws of such  jurisdictions  within the United States as
any selling Holder or underwriter reasonably requests in writing, keep each such
registration  or  qualification  effective  during the period such  Registration
Statement  is  required  to be kept  effective  and do any and all other acts or
things necessary or advisable to enable the disposition in such jurisdictions of
the Registrable  Securities  covered by the applicable  Registration  Statement;
provided  that the Company will not be required to qualify to do business in any
jurisdiction  where it not then so  qualified  or to take any action which would
subject the Company to general service of process in any  jurisdiction  where it
is not at the time so subject;


                                      A-24



                                                      


                  (i)  cooperate   with  the  selling   Holders  of  Registrable
Securities  and the  managing  underwriters,  if any, to  facilitate  the timely
preparation and delivery of certificates  representing Registrable Securities to
be sold and not bearing any  restrictive  legends;  and enable such  Registrable
Securities  to be in such  denominations  and  registered  in such  names as the
managing  underwriters  may request at least two Business Days prior to any sale
of Registrable Securities to the underwriters;

                  (j) use its best efforts to cause the  Registrable  Securities
covered  by the  applicable  Registration  Statement  to be  registered  with or
approved by such other  governmental  agencies or authorities  within the United
States as may be  necessary  to enable  the  seller or  sellers  thereof  or the
underwriters,  if  any,  to  consummate  the  disposition  of  such  Registrable
Securities;

                  (k) upon the occurrence of any event  contemplated  by Section
6.4(c)(vi)  above,  prepare a  supplement  or  post-effective  amendment  to the
applicable   Registration  Statement  or  related  Prospectus  or  any  document
incorporated  therein by reference or file any other required  document so that,
as thereafter  delivered to the purchasers of the Registrable  Securities  being
sold  thereunder,  such  Prospectus  will not contain an untrue  statement  of a
material  fact or  omit  to  state  any  material  fact  necessary  to make  the
statements therein not misleading;

                  (l)  with  respect  to each  issue  or  class  of  Registrable
Securities,  use its best efforts to cause all Registrable Securities covered by
the  Registration  Statements  to be  listed  on  each  securities  exchange  or
automated  quotation system,  if any, on which similar  securities issued by the
Company are then listed if  requested by the Holders of a majority of such issue
or class of Registrable Securities;

                  (m) enter  into such  agreements  (including  an  underwriting
agreement)  and take all such other  action  reasonably  required in  connection
therewith in order to expedite or facilitate the disposition of such Registrable
Securities and in such connection,  if the registration is in connection with an
underwritten  offering  (i) make  such  representations  and  warranties  to the
underwriters  (or the Holders of the Registrable  Securities if such offering is
not underwritten),  in such form, substance and scope as are customarily made by
issuers to underwriters  in  underwritten  offerings and confirm the same if and
when  requested;  (ii)  obtain  opinions  of counsel to the  Company and updates
thereof


                                      A-25



                                                      


(which  counsel and opinions in form,  scope and  substance  shall be reasonably
satisfactory to the underwriters)  addressed to the underwriters (or the Holders
of the Registrable Securities if such offering is not underwritten) covering the
matters customarily covered in opinions requested in underwritten  offerings and
such other matters as may be reasonably  requested by such  underwriters (or the
Holders of the  Registrable  Securities if such  offering is not  underwritten);
(iii)  obtain "cold  comfort"  letters and updates  thereof  from the  Company's
accountants  addressed to the  underwriters  (or the Holders of the  Registrable
Securities  if  such  offering  is  not  underwritten),  such  letters  to be in
customary  form and covering  matters of the type  customarily  covered in "cold
comfort" letters by underwriters in connection with underwritten offerings; (iv)
set forth in full in any underwriting agreement entered into the indemnification
provisions  and  procedures of Section 6.5 hereof with respect to all parties to
be  indemnified  pursuant to said  Section;  and (v) deliver such  documents and
certificates  as may be  reasonably  requested by the  underwriters  to evidence
compliance with clause (i) above and with any customary  conditions contained in
the underwriting  agreement or other agreement entered into by the Company;  the
above shall be done at each closing under such underwriting or similar agreement
or as and to the extent required hereunder;

                  (n)   make   available   for   inspection   by  one  or   more
representatives  of the  Holders  of  Registrable  Securities  being  sold,  any
underwriter participating in any disposition pursuant to such registration,  and
any  attorney  or  accountant  retained  by such  Holders  or  underwriter,  all
financial and other records, pertinent corporate documents and properties of the
Company, and cause the Company's officers, directors and employees to supply all
information reasonably requested by any such representatives, in connection with
such; and

                  (o)  otherwise  use  its  best  efforts  to  comply  with  all
applicable Federal and state  regulations;  and take such other action as may be
reasonably  necessary  to or  advisable to enable each such Holder and each such
underwriter  to  consummate  the sale or  disposition  in such  jurisdiction  or
jurisdiction  in which any such Holder or underwriter  shall have requested that
the Registrable Securities be sold.

         Except as otherwise provided in this Agreement,  the Company shall have
sole control in connection with the preparation,  filing, withdrawal,  amendment
or supplementing of each Registration Statement,  the selection of underwriters,
and

                                      A-26



                                                      


the  distribution of any  preliminary  prospectus  included in the  Registration
Statement,  and may include  within the coverage  thereof  additional  shares of
Common Stock or other  securities  for its own account or for the account of one
or more of its other security holders.

         The Company may require  each Seller of  Registrable  Securities  as to
which  any  registration  is being  effected  to  furnish  to the  Company  such
information  regarding  the  distribution  of such  securities  and  such  other
information as may otherwise be required by the Securities Act to be included in
such Registration Statement.

6.5      INDEMNIFICATION

                  (a)  Indemnification  by  Company.  In  connection  with  each
Registration  Statement relating to disposition of Registrable  Securities,  the
Company shall indemnify and hold harmless each Holder,  its officers,  directors
and agents and each  underwriter of Registrable  Securities and each Person,  if
any, who controls such Holder or  underwriter  (within the meaning of Section 15
of the  Securities  Act or Section 20 of the  Exchange  Act) against any and all
losses,  claims,  damages  and  liabilities,  joint or  several  (including  any
reasonable investigation,  legal and other expenses incurred in connection with,
and any amount paid in settlement of any action, suit or proceeding or any claim
asserted),  to  which  they,  or any of  them,  may  become  subject  under  the
Securities Act, the Exchange Act or other federal or state law or regulation, at
common law or otherwise,  insofar as such losses, claims, damages or liabilities
arise out of or are based upon any untrue  statement or alleged untrue statement
of a material  fact  contained  in any  Registration  Statement,  Prospectus  or
preliminary  prospectus or any amendment thereof or supplement thereto, or arise
out of or are based upon any  omission or alleged  omission  to state  therein a
material fact required to be stated  therein or necessary to make the statements
therein not misleading;  provided,  however, that such indemnity shall not inure
to the  benefit of any Holder or  underwriter  (or any Person  controlling  such
Holder or underwriter  within the meaning of Section 15 of the Securities Act or
Section 20 of the  Exchange  Act) on account of any losses,  claims,  damages or
liabilities  arising from the sale of the Registrable  Securities if such untrue
statement or omission or alleged  untrue  statement or omission was made in such
Registration Statement,  Prospectus or preliminary prospectus, or such amendment
or supplement,  in reliance upon and in conformity with information furnished in
writing  to the  Company  by such  Holder or  underwriter  specifically  for

                                      A-27


                                                      


use therein.  The Company shall also indemnify selling brokers,  dealer managers
and similar securities industry professionals participating in the distribution,
their  officers and directors and each Person who controls such Persons  (within
the meaning of Section 15 of the  Securities  Act or Section 20 of the  Exchange
Act) to the same extent as provided above with respect to the indemnification of
the Holders of Registrable  Securities,  if requested.  This indemnity agreement
shall be in addition to any liability which the Company may otherwise have.

                  (b)   Indemnification  by  Holder.  In  connection  with  each
Registration  Statement,  each Holder shall indemnify, to the same extent as the
indemnification  provided by the Company in Section  6.5(a),  the  Company,  its
directors and each officer who signs the Registration  Statement and each Person
who controls the Company (within the meaning of Section 15 of the Securities Act
and Section 20 of the Exchange  Act) but only  insofar as such  losses,  claims,
damages and liabilities  arise out of or are based upon any untrue  statement or
omission  or  alleged  untrue  statement  or  omission  which  was  made  in the
Registration  Statement,   the  Prospectus  or  preliminary  prospectus  or  any
amendment thereof or supplement thereto, in reliance upon and in conformity with
information  furnished in writing by such Holder to the Company specifically for
use  therein.  In no  event  shall  the  liability  of  any  selling  Holder  of
Registrable  Securities hereunder be greater in amount than the dollar amount of
the net  proceeds  received  by such  Holder  upon the  sale of the  Registrable
Securities giving rise to such indemnification  obligation. The Company shall be
entitled to receive  indemnities  from  underwriters,  selling  brokers,  dealer
managers and similar  securities  industry  professionals  participating  in the
distribution,  to the same extent as provided above, with respect to information
so  furnished  in writing by such  Persons  specifically  for  inclusion  in any
Prospectus,  Registration  Statement or preliminary  prospectus or any amendment
thereof or supplement thereto.

                  (c)  Conduct  of  Indemnification  Procedure.  Any party  that
proposes to assert the right to be indemnified  hereunder  will,  promptly after
receipt of notice of commencement of any action, suit or proceeding against such
party in respect of which a claim is to be made against an indemnifying party or
parties  under  this  Section,  notify  each  such  indemnifying  party  of  the
commencement of such action, suit or proceeding,  enclosing a copy of all papers
served.  No  indemnification  provided for in Section  6.5(a) or 6.5(b) shall be
available to any party who shall fail to give notice as provided in this Section
6.5(c) if the party to whom notice was not given was  unaware of the  proceeding
to which such notice

                                      A-28



                                                      


would have related and was  prejudiced  by the failure to give such notice,  but
the omission so to notify such  indemnifying  party of any such action,  suit or
proceeding  shall  not  relieve  it from any  liability  that it may have to any
indemnified  party for contribution  otherwise than under this Section.  In case
any such action,  suit or proceeding  shall be brought  against any  indemnified
party and it shall notify the indemnifying  party of the  commencement  thereof,
the  indemnifying  party shall be entitled to participate in, and, to the extent
that it  shall  wish,  jointly  with  any  other  indemnifying  party  similarly
notified,  to assume the defense  thereof,  with  counsel  satisfactory  to such
indemnified  party,  and  after  notice  from  the  indemnifying  party  to such
indemnified  party of its  election  so to assume the  defense  thereof  and the
approval by the indemnified party of such counsel,  the indemnifying party shall
not be liable to such indemnified party for any legal or other expenses,  except
as  provided  below  and  except  for  the  reasonable  costs  of  investigation
subsequently  incurred by such indemnified  party in connection with the defense
thereof. The indemnified party shall have the right to employ its counsel in any
such action,  but the fees and expenses of such counsel  shall be at the expense
of  such  indemnified  party  unless  (i)  the  employment  of  counsel  by such
indemnified  party has been authorized in writing by the  indemnifying  parties,
(ii) the indemnified  party shall have reasonably  concluded that there may be a
conflict of interest between the indemnifying  parties and the indemnified party
in the  conduct of the  defense of such  action (in which case the  indemnifying
parties  shall not have the right to direct the defense of such action on behalf
of the  indemnified  party) or (iii)  the  indemnifying  parties  shall not have
employed  counsel to assume the defense of such action within a reasonable  time
after notice of the  commencement  thereof,  in each of which cases the fees and
expenses of counsel  shall be at the  expense of the  indemnifying  parties.  An
indemnified  party shall not be liable for any  settlement of any action,  suit,
proceeding or claim effected without its written consent.

                  (d)   Contribution.   In  connection  with  each  Registration
Statement  relating  to  the  disposition  of  Registrable  Securities,  if  the
indemnification  provided  for in  subsection  (a) hereof is  unavailable  to an
indemnified  party  thereunder  in respect  to any  losses,  claims,  damages or
liabilities referred to therein, then the indemnifying party shall contribute to
the amount paid or payable by such indemnified  party as a result of the losses,
claims,  damages or  liabilities  referred  to in  paragraph  (a) or (b) of this
Section 6.5 in such  proportion as is  appropriate to reflect the relative fault
of the  indemnifying  party on the one hand and of the indemnified  party on the
other in  connection  with the  statements  or omissions  that

                                      A-29



                                                      


resulted in such losses, claims,  damages or liabilities,  or actions in respect
thereof, as well as any other relevant equitable considerations.  Relative fault
shall be determined  by reference to, among other things,  whether the untrue or
alleged untrue  statement of a material fact or the omission or alleged omission
to state a material  fact relates to  information  supplied by the  indemnifying
party or the  indemnified  party and the parties'  relative  intent,  knowledge,
access to  information  and  opportunity  to  correct  or  prevent  such  untrue
statement or omission.  Notwithstanding anything to the contrary in this Section
6.5(d),  no  selling  Holder of  Registrable  Securities  shall be  required  to
contribute  any amount in excess of the net  proceeds it received in  connection
with its sale of Registrable Securities.

                  (e)  Underwriting  Agreement to Control.  Notwithstanding  the
foregoing  provisions of this Section 6.5, to the extent that the  provisions on
indemnification and contribution contained in any underwriting agreement entered
into in connection  with the  underwritten  public  offering of the  Registrable
Securities are in conflict with the foregoing provisions, the provisions in such
underwriting agreement shall control.

                  (f)   Specific   Performance.   The  Company  and  the  Holder
acknowledge  that remedies at law for the enforcement of this Section 6.5 may be
inadequate and intend that this Section 6.5 shall be specifically enforceable.

                  (g) Survival of  Obligations.  The  obligations of the Company
and the Holder  under this  Section  6.5 shall  survive  the  completion  of any
offering of Registrable  Securities  pursuant to a Registration  Statement under
this Article 6, and otherwise.

6.6      REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934

         With a view to making available to the Holders the benefits of Rule 144
promulgated under the Securities Act and any other rule or regulation of the SEC

Registrable  Securities,  forthwith upon request (i) a written  statement by the
Company that it has complied with the reporting requirements of SEC Rule 144 (at
any time  after 90 days  after  the  effective  date of the  first  registration
statement filed by the Company), the Securities Act and the Exchange Act (at any
time after it has become  subject to such  reporting  requirements),  or that it
qualifies as a registrant  whose  securities may be resold  pursuant to Form S-3
(at any time after it so  qualifies),  (ii) a copy of the most recent  annual or
quarterly report of the Company and such other reports and documents so filed by
the Company,  and (iii) such other information as may be reasonably requested in
availing  any  Holder of any rule or  regulation  of the SEC which  permits  the
selling of any such securities without registration or pursuant to such form.

                                    ARTICLE 7

Oscar Gruss & Son Incorporated
Kaufman Bros., L.P.
As Representative of the several Underwriters
c/o Oscar Gruss & Son Incorporated
74 Broad Street
New York, New York 10004

Ladies and Gentlemen:

         The  undersigned   understands  that  you  propose  to  enter  into  an
Underwriting  Agreement (the  "Underwriting  Agreement") with Boston  Biomedica,
Inc. (the  "Company")  providing for the purchase by you and certain other firms
(the  "Underwriters")  of shares (the "Shares") of Common Stock, par value $0.01
per share (the "Common Stock"), of the Company and that the Underwriters propose
to offer the Shares to the public. The undersigned  further understands that the
proposed sale of such Shares is the subject of a Registration  Statement on Form
S-1 which will be filed with the  Securities  and Exchange  Commission and which
will include a form of preliminary prospectus to be used in offering such Shares
to the public.

         In consideration of the execution of the Underwriting  Agreement by the
Underwriters,  and for other good and valuable  consideration,  the  undersigned
hereby  irrevocably agrees that without the prior written consent of Oscar Gruss
& Son  Incorporated,  which  consent may be withheld in the sole  discretion  of
Oscar  Gruss & Son  Incorporated,  the  undersigned  will not (i) offer to sell,
contract  to sell,  sell,  distribute,  grant any  option to  purchase,  pledge,
hypothecate,  or otherwise  dispose of,  directly or  indirectly,  any shares of
Common Stock, or any securities convertible into, or exercisable or exchangeable
for, shares of Common Stock for a period of 180 days after the date of the final
prospectus  relating  to  the  offering


                                      B-1



                                                      


of the Shares to the public by the  Underwriter  except for the  exercise by the
undersigned  of  outstanding  options  granted by the Company or pursuant to any
options  granted or to be granted  pursuant to employee  stock option plans (but
not the sale, distribution, pledge, hypothecation or other disposition of Common
Stock  received upon such  exercise) or (ii) in connection  with the offering of
the Shares to the public by the  Underwriter  and for 365 days after the date of
the final prospectus relating thereto exercise any registration rights,  whether
held by the undersigned on the date hereof or hereafter  acquired,  with respect
to  any  shares  of  Common  Stock,  or  any  securities  convertible  into,  or
exercisable or exchangeable for, shares of Common Stock. Prior to the expiration
of such periods,  the undersigned will not announce or disclose any intention to
do anything  after the  expiration  of such  periods  which the  undersigned  is
prohibited,  as  provided  in the  preceding  sentence,  from doing  during such
periods. After such periods, all shares of Common Stock owned by the undersigned
may be sold or registered,  as the case may be, without  restriction  hereunder,
subject to applicable securities laws and regulations.

         The  undersigned  agrees that the provisions of this Agreement shall be
binding upon the successors,  assigns, heirs and personal representatives of the
undersigned.

         In  furtherance  of the  foregoing,  the  undersigned  agrees  that the
Company  and its  transfer  agent are hereby  authorized  to decline to make any
transfer of securities if such transfer  would  constitute a violation or breach
of this Agreement.

         It is understood  that, if the  Underwriting  Agreement does not become
effective prior to  ________________,  or if the  Underwriting  Agreement (other
than the provisions  thereof which survive  termination)  shall  terminate or be
terminated  prior to payment for and delivery of the Shares,  the  undersigned's
obligations under this Agreement shall terminate.

                                                Very truly yours,
